    Full Text Available Abstract Background Chronic pain is prevalent among young people and negatively influences their quality of life. Furthermore, chronic pain in adolescence may persist into adulthood. Therefore, it is important early on to promote the self-management skills of adolescents with chronic pain by improving signaling, referral, and treatment of these youngsters. In this study protocol we describe the designs of two complementary studies: a signaling study and an intervention study. Methods and design The signaling study evaluates the Pain Barometer, a self-assessed signaling instrument for chronic pain in adolescents. To evaluate the feasibility of the Pain Barometer, the experiences of youth-health care nurses will be evaluated in semi-structured interviews. Also, we will explore the frequencies of referral per health-care provider. The intervention study evaluates Move It Now, a guided self-help intervention via the Internet for teenagers with chronic pain. This intervention uses cognitive behavioural techniques, including relaxation exercises and positive thinking. The objective of the intervention is to improve the ability of adolescents to cope with pain. The efficacy of Move It Now will be examined in a randomized controlled trial, in which 60 adolescents will be randomly assigned to an experimental condition or a waiting list control condition. Discussion If the Pain Barometer is proven to be feasible and Move It Now appears to be efficacious, a health care pathway can be created to provide the best tailored treatment promptly to adolescents with chronic pain. Move It Now can be easily implemented throughout the Netherlands, as the intervention is Internet based. Trial registration Dutch Trial Register NTR1926

    Full Text Available Purpose Adolescents are often cited as having poor rates of compliance with medical regimens and research protocols. We quantified compliance in a cohort of urban adolescents participating in a complex research protocol in which measures were obtained without direct supervision by research personnel. Methods A total of 54 early adolescents ages 10-13 were asked to wear a vest containing a personal air pollutant exposure monitor for two 24-hour periods and to perform daily peak expiratory flow (PEF for six consecutive days. Compliance with wearing the vest was measured by comparing accelerometer data from a device within the vest to one worn continuously on the child's wrist. Daily PEF data were recorded using an electronic meter. Results A priori definition of compliance was met by 85% of the adolescents by wearing the exposure monitoring vest and 72% by performing PEF. Conclusions These findings suggest that early adolescents can be compliant with complex research protocols that are needed to help bridge gaps in pediatric asthma research.

    Full Text Available Abstract Background Determining risky behaviours of adolescents provides valuable information for designing appropriate intervention programmes for advancing adolescent’s health. However, these behaviours are not fully addressed by researchers in a comprehensive approach. We report the protocol of a mixed methods study designed to investigate the health risk behaviours of Moroccan adolescents with the goal of identifying suitable strategies to address their health concerns. Methods We used a sequential two-phase explanatory mixed method study design. The approach begins with the collection of quantitative data, followed by the collection of qualitative data to explain and enrich the quantitative findings. In the first phase, the global school-based student health survey (GSHS was administered to 800 students who were between 14 and 19 years of age. The second phase engaged adolescents, parents and teachers in focus groups and assessed education documents to explore the level of coverage of health education in the programme learnt in the middle school. To obtain opinions about strategies to reduce Moroccan adolescents’ health risk behaviours, a nominal group technique will be used. Discussion The findings of this mixed methods sequential explanatory study provide insights into the risk behaviours that need to be considered if intervention programmes and preventive strategies are to be designed to promote adolescent’s health in the Moroccan school.

    Previous research shows that adolescents with autism spectrum disorder (ASD) run several risks in their psychosexual development and that these adolescents can have limited access to reliable information on puberty and sexuality, emphasizing the need for specific guidance of adolescents with ASD in their psychosexual development. Few studies have investigated the effects of psychosexual training programs for adolescents with ASD and to date no randomized controlled trials are available to study the effects of psychosexual interventions for this target group. The randomized controlled trial (RCT) described in this study protocol aims to investigate the effects of the Tackling Teenage Training (TTT) program on the psychosexual development of adolescents with ASD. This parallel clinical trial, conducted in the South-West of the Netherlands, has a simple equal randomization design with an intervention and a waiting-list control condition. Two hundred adolescents and their parents participate in this study. We assess the participants in both conditions using self-report as well as parent-report questionnaires at three time points during 1 year: at baseline (T1), post-treatment (T2), and for follow-up (T3). To our knowledge, the current study is the first that uses a randomized controlled design to study the effects of a psychosexual training program for adolescents with ASD. It has a number of methodological strengths, namely a large sample size, a wide range of functionally relevant outcome measures, the use of multiple informants, and a standardized research and intervention protocol. Also some limitations of the described study are identified, for instance not making a comparison between two treatment conditions, and no use of blinded observational measures to investigate the ecological validity of the research results.

    Adolescents with low motor competence participate less in physical activity and tend to exhibit decreased physical fitness compared to their peers with high motor competence. It is therefore essential to identify new methods of enhancing physical fitness in this population. Active video games (AVG) have been shown to improve motor performance, yet investigations of its impact on physical fitness are limited. The objective of this study was to examine the impact of the graded Wii protocol in adolescent girls with probable Developmental Coordination Disorder (p-DCD). A single-group pre-post design was conducted to assess the impact of a newly developed Wii protocol in adolescent girls attending school in a low income community of Cape Town, South Africa. Sixteen participants (aged 13-16 years) with p-DCD (≤16th percentile on the MABC-2 test) were recruited. Participants received 45 min Wii training for 14 weeks. Outcome measures included the six-minute walk distance and repeated sprint ability. Information on heart rate, enjoyment and perceived exertion ratings were also collected. Significant improvements in aerobic and anaerobic fitness were observed. The participants reported high enjoyment scores and low perceived exertion ratings. The graded Wii protocol was easily adaptable and required little resources (space, equipment and expertise) to administer. The findings provide preliminary evidence to support the use of the graded Wii protocol for promoting physical fitness in adolescent girls with p-DCD. Further studies are needed to confirm these results and to validate the clinical efficacy of the protocol in a larger sample with a more robust design.

    The impact of severe malnutrition and medical instability in adolescent Anorexia Nervosa (AN) on immediate health and long-term development underscores the need for safe and efficient methods of refeeding. Current refeeding guidelines in AN advocate low initial caloric intake with slow increases in energy intake to avoid refeeding syndrome. This study demonstrates the potential for more rapid refeeding to promote initial weight recovery and correct medical instability in adolescent AN. Seventy-eight adolescents with AN (12-18 years), hospitalised in two specialist paediatric eating disorder units, for medical instability (bradycardia, hypotension, hypothermia, orthostatic instability and/or cardiac arrhythmia) were followed during a 2.5 week admission. Patients were refed using a standardised protocol commencing with 24-72 hours of continuous nasogastric feeds (ceased with daytime medical stability) and routine oral phosphate supplementation, followed by nocturnal feeds and a meal plan of 1200-2400 kcal/day aiming for a total caloric intake of 2400-3000 kcal/day. Along with indicators of medical stability, weight, phosphate and glucose levels were recorded. All patients gained weight in week one (M = 2.79 kg, SD = 1.27 kg) and at subsequent measurement points with an average gain of 5.12 kg (SD = 2.96) at 2.5 weeks. No patient developed hypophosphatemia, hypoglycaemia, or stigmata of the refeeding syndrome. The refeeding protocol resulted in immediate weight gain and was well tolerated with no indicators of refeeding syndrome. There were no significant differences in outcomes between the treatment sites, suggesting the protocol is replicable. Australian Clinical Trials Register number: ACTRN012607000009415.

    Advances in care and treatment of adolescents/young adults with HIV infection have made survival into adulthood possible, requiring transition to adult care. Researchers have documented that the transition process is challenging for adolescents/young adults. To ensure successful transition, a formal transition protocol is needed. Despite existing research, little quantitative evaluation of the transition process has been conducted. The purpose of the study was to pilot test the "Movin' Out" Transitioning Protocol, a formalized protocol developed to assist transition to adult care. A retrospective medical/nursing record review was conducted with 38 clients enrolled in the "Movin' Out" Transitioning Protocol at a university-based adolescent medicine clinic providing care to adolescents/young adults with HIV infection. Almost half of the participants were able to successfully transition to adult care. Reasons for failure to transition included relocation, attrition, lost to follow-up, and transfer to another adult service. Failure to transition to adult care was not related to adherence issues, X(2) (1, N=38)=2.49, p=.288; substance use, X(2) (1, N=38)=1.71, p=.474; mental health issues, X(2) (1, N=38)=2.23, p=.322; or pregnancy/childrearing, X(2) (1, N=38)=0.00, p=.627). Despite the small sample size, the "Movin' Out" Transitioning Protocol appears to be useful in guiding the transition process of adolescents/young adults with HIV infection to adult care. More research is needed with a larger sample to fully evaluate the "Movin' Out" Transitioning Protocol. Copyright © 2015 Elsevier Inc. All rights reserved.

    Most studies comparing prevalence of periodontal disease and risk factors by using partial protocols were performed in adult populations, with several studies being conducted in clinical settings. The aim of this study is to assess the accuracy of partial protocols in estimating the prevalence of periodontal outcomes in adolescents and young adults from two population-based birth cohorts from Pelotas, Brazil, and to assess differences in the estimation and strength of the effect measures when partial protocols are adopted compared to full-mouth examination. Gingival bleeding at probing among adolescents (n = 339) and young adults (n = 720) and dental calculus and periodontal probing depth among young adults were assessed using full-mouth examinations and four partial protocols: Ramfjord teeth (RT), community periodontal index (CPI), and two random diagonal quadrants (1 and 3, 2 and 4). Socioeconomic, demographic, and periodontal health-related variables were also collected. Sensitivity, absolute and relative bias, and inflation factors were calculated. Prevalence ratio for each periodontal outcome for the risk factors was estimated. Two diagonal quadrants showed better accuracy; RT had the worst, whereas CPI presented an intermediate pattern when compared to full-mouth examination. For bleeding assessment in adolescence, RT and CPI underestimated by 18.4% and 16.2%, respectively, the true outcome prevalence, whereas among young adults, all partial protocols underestimated the prevalence. All partial protocols presented similar magnitude of association measures for all investigated periodontal potential risk factors. Two diagonal quadrants protocol may be effective in identifying the risk factors for the most relevant periodontal outcomes in adolescence and in young adulthood.

    The superiority of the pediatric protocol for adolescents with acute lymphoblastic leukemia (ALL) has already been demonstrated, however, its efficacy in young adults remains unclear. The ALL202-U protocol was conducted to examine the efficacy and feasibility of a pediatric protocol in adolescents and young adults (AYAs) with BCR–ABL-negative ALL. Patients aged 15–24 years (n=139) were treated with the same protocol used for pediatric B-ALL. The primary objective of this study was to assess the disease-free survival (DFS) rate and its secondary aims were to assess toxicity, the complete remission (CR) rate and the overall survival (OS) rate. The CR rate was 94%. The 5-year DFS and OS rates were 67% (95% confidence interval (CI) 58–75%) and 73% (95% CI 64–80%), respectively. Severe adverse events were observed at a frequency that was similar to or lower than that in children treated with the same protocol. Only insufficient maintenance therapy significantly worsened the DFS (hazard ratio 5.60, P<0.001). These results indicate that this protocol may be a feasible and highly effective treatment for AYA with BCR–ABL-negative ALL

    To compare the performance of partial-mouth periodontal examination (PMPE) protocols with different cut-off points to the full-mouth examination (FME) in the assessment of the prevalence and extent of gingival bleeding in adolescents. A cross-sectional study was conducted involving 12-year-old adolescents. Following a systematic two-stage cluster sampling process, 1134 individuals were evaluated. Different PMPE protocols were compared to the FME with six sites per tooth. Sensitivity, specificity, area under the ROC curve (AUC), intraclass correlation coefficient (ICC), relative and absolute biases and the inflation factor were assessed for each PMPE protocol with different cut-off points for the severity of gingival bleeding. The highest AUC values were found for the six-site two-diagonal quadrant (2-4) (0.97), six-site random half-mouth (0.95) and Community Periodontal Index (0.95) protocols. The assessment of three sites [mesiobuccal (MB), buccal (B) and distolingual (DL)] in two diagonal quadrants and the random half-mouth protocol had higher sensitivity and lower specificity than the same protocols with distobuccal (DB) sites. However, the use of DB sites led to better specificity and improved the balance between sensitivity and specificity, except for the two-diagonal quadrant (1-3) protocol. The ≥1 cut-off point led to the most discrepant results from the FME. Six-site two-diagonal quadrant (2-4) and random half-mouth assessments perform better in the evaluation of gingival bleeding in adolescents. However, when a faster protocol is needed, a two-diagonal quadrant assessment using only MB, B and DL sites can be used with no important loss of information. © 2017 John Wiley & Sons A/S.

    Full Text Available Abstract Background This protocol is for a study of a new program to improve outcomes in children suffering from chronic pain disorders, such as fibromyalgia, recurrent headache, or recurrent abdominal pain. Although teaching active pain self-management skills through cognitive-behavioral therapy (CBT or a complementary program such as hypnotherapy or yoga has been shown to improve pain and functioning, children with low expectations of skill-building programs may lack motivation to comply with therapists' recommendations. This study will develop and test a new manualized peer-mentorship program which will provide modeling and reinforcement by peers to other adolescents with chronic pain (the mentored participants. The mentorship program will encourage mentored participants to engage in therapies that promote the learning of pain self-management skills and to support the mentored participants' practice of these skills. The study will examine the feasibility of this intervention for both mentors and mentored participants, and will assess the preliminary effectiveness of this program on mentored participants' pain and functional disability. Methods This protocol will recruit adolescents ages 12-17 with chronic pain and randomly assign them to either peer mentorship or a treatment-as-usual control group. Mentored participants will be matched with peer mentors of similar age (ages 14-18 who have actively participated in various treatment modalities through the UCLA Pediatric Pain Program and have learned to function successfully with a chronic pain disorder. The mentors will present information to mentored participants in a supervised and monitored telephone interaction for 2 months to encourage participation in skill-building programs. The control group will receive usual care but without the mentorship intervention. Mentored and control subjects' pain and functioning will be assessed at 2 months (end of intervention for mentored participants and

    Impairments in macrovascular, microvascular and autonomic function are present in asymptomatic youths with clustered cardiovascular disease risk factors. This study determines the within-day reliability and between-day reliability of a single protocol to non-invasively assess these outcomes in adolescents. Forty 12- to 15-year-old adolescents (20 boys) visited the laboratory in a fasted state on two occasions, approximately 1 week apart. One hour after a standardized cereal breakfast, macrovascular function was determined via flow-mediated dilation (FMD). Heart rate variability (root mean square of successive R-R intervals; RMSSD) was determined from the ECG-gated ultrasound images acquired during the FMD protocol prior to cuff occlusion. Microvascular function was simultaneously quantified as the peak (PRH) and total (TRH) hyperaemic response to occlusion in the cutaneous circulation of the forearm via laser Doppler imaging. To address within-day reliability, a subset of twenty adolescents (10 boys) repeated these measures 90 min afterwards on one occasion. The within-day typical error and between-day typical error expressed as a coefficient of variation of these outcomes are as follows: ratio-scaled FMD, 5·1% and 10·6%; allometrically scaled FMD, 4·4% and 9·4%; PRH, 11% and 13·3%; TRH, 29·9% and 23·1%; and RMSSD, 17·6% and 17·6%. The within- and between-day test-retest correlation coefficients for these outcomes were all significant (r > 0·54 for all). Macrovascular, microvascular and autonomic functions can be simultaneously and non-invasively determined in adolescents using a single protocol with an appropriate degree of reproducibility. Determining these outcomes may provide greater understanding of the progression of cardiovascular disease and aid early intervention. © 2016 Scandinavian Society of Clinical Physiology and Nuclear Medicine.

    Obesity, eating disorders and unhealthy weight-loss practices have been associated with diminished growth in adolescents worldwide. Interventions that address relevant behavioural dimensions have been lacking in Malaysia. This paper describes the protocol of an integrated health education intervention namely 'Eat Right, Be Positive About Your Body and Live Actively' (EPaL), a primary prevention which aimed to promote healthy lifestyle in preventing overweight and disordered eating among secondary school adolescents aged 13-14 years old. Following quasi-experimental design, the intervention is conducted in two secondary schools located in the district of Hulu Langat, Selangor, Malaysia. Adolescents aged 13-14 years will be included in the study. A peer-education strategy is adopted to convey knowledge and teach skills relevant to achieving a healthy lifestyle. The intervention mainly promoted: healthy eating, positive body image and active lifestyle. The following parameters will be assessed: body weight, disordered eating status, stages of change (for healthy diet, breakfast, food portion size, screen viewing and physical activity), body image, health-related quality of life, self-esteem, eating and physical activity behaviours; and knowledge, attitude and practice towards a healthy lifestyle. Assessment will be conducted at three time points: baseline, post-intervention and 3-month follow-up. It is hypothesized that EPaL intervention will contribute in preventing overweight and disordered eating by giving the positive effects on body weight status, healthy lifestyle behaviour, as well as health-related quality of life of peer educators and participants. It may serve as a model for similar future interventions designed for the Malaysian community, specifically adolescents. UMIN Clinical Trial Registration UMIN000024349 (Date of registration: 11th.

    Full Text Available The challenge of combining elite sport and education into a dual career pathway remains to be a source of concern for many high-performance athletes. Previous research findings suggest that committed participation in both domains is highly demanding and success in one pursuit often comes at the expense of the other. There are emergent studies, however, that argue for the beneficial and complementary nature of dual career pathways. Consequently, we emphasize the importance of understanding the processes underlying differences in the development of athletes’ life trajectories. This article presents a study protocol to explore new methodological and analytical approaches that may extend current understandings of the ways psychological and sociocultural processes are interconnected in the construction of adolescent athletes’ identities, motivation, well-being, and career aspirations in the transitory social world.

    Full Text Available Abstract Background There is a need to develop sustainable and clinically effective weight management interventions that are suitable for delivery in community settings where the vast majority of overweight and obese adolescents should be treated. This study aims to evaluate the effect of additional therapeutic contact as an adjunct to the Loozit® group program – a community-based, lifestyle intervention for overweight and lower grade obesity in adolescents. The additional therapeutic contact is provided via telephone coaching and either mobile phone Short Message Service or electronic mail, or both. Methods and design The study design is a two-arm randomised controlled trial that aims to recruit 168 overweight and obese 13–16 year olds (Body Mass Index z-score 1.0 to 2.5 in Sydney, Australia. Adolescents with secondary causes of obesity or significant medical illness are excluded. Participants are recruited via schools, media coverage, health professionals and several community organisations. Study arm one receives the Loozit® group weight management program (G. Study arm two receives the same Loozit® group weight management program plus additional therapeutic contact (G+ATC. The 'G' intervention consists of two phases. Phase 1 involves seven weekly group sessions held separately for adolescents and their parents. This is followed by phase 2 that involves a further seven group sessions held regularly, for adolescents only, until two years follow-up. Additional therapeutic contact is provided to adolescents in the 'G+ATC' study arm approximately once per fortnight during phase 2 only. Outcome measurements are assessed at 2, 12 and 24 months post-baseline and include: BMI z-score, waist z-score, metabolic profile indicators, physical activity, sedentary behaviour, eating patterns, and psychosocial well-being.

    Full Text Available Abstract Background Adolescents in less developed countries such as Zambia often face multi-faceted challenges for achieving successful transitions through adolescence to early adulthood. The literature has noted the need to introduce interventions during this period, particularly for adolescent girls, with the perspective that such investments have significant economic, social and health returns to society. The Adolescent Girls Empowerment Programme (AGEP was an intervention designed as a catalyst for change for adolescent girls through themselves, to their family and community. Methods/design AGEP was a multi-sectoral intervention targeting over 10,000 vulnerable adolescent girls ages 10–19 in rural and urban areas, in four of the ten provinces of Zambia. At the core of AGEP were mentor-led, weekly girls’ group meetings of 20 to 30 adolescent girls participating over two years. Three curricula ― sexual and reproductive health and lifeskills, financial literacy, and nutrition ― guided the meetings. An engaging and participatory pedagogical approach was used. Two additional program components, a health voucher and a bank account, were offered to some girls to provide direct mechanisms to improve access to health and financial services. Embedded within AGEP was a rigorous multi-arm randomised cluster trial with randomization to different combinations of programme arms. The study was powered to assess the impact across a set of key longer-term outcomes, including early marriage and first birth, contraceptive use, educational attainment and acquisition of HIV and HSV-2. Baseline behavioural surveys and biological specimen collection were initiated in 2013. Impact was evaluated immediately after the program ended in 2015 and will be evaluated again after two additional years of follow-up in 2017. The primary analysis is intent-to-treat. Qualitative data are being collected in 2013, 2015 and 2017 to inform the programme implementation and the

    Full Text Available Background: Bullying perpetration and victimization is associated with significant academic, psychosocial and health related problems among adolescents. There is a need to develop effective interventions to prevent bullying among adolescents, especially in low and middle income countries. This paper presents the study protocol to develop, and evaluate the effect of multi-component school based prevention program for bullying in India. Design: Quasi-experimental study. Methods: The study will be conducted among 846 students of grade 7th and 8th in the intervention and control schools in Chandigarh, Union Territory, North India. A government and a private school will be selected purposively in each of the intervention and control arm. The intervention is based on socio-ecological model, and will be administered at individual, relationship (parents and teachers and school level. The primary study outcome will be the proportion of students experiencing any kind of bullying (bullying, victimization, or both, in each study arm. The effectiveness of the intervention will be measured by performing difference in difference analysis and generalized estimating equations. Expected impact for public health: Bullying is an aggressive behaviour with significant morbidities, including psychological or physical trauma, affecting individuals not only in their adolescence, but also later in their adulthood. This quasi-experimental study is expected to provide evidence on whether multi-component bullying prevention intervention program, can reduce the burden of bullying perpetration and victimization among school adolescents in India. The results of the study will add in the exiting literature on bullying intervention program, especially, from the low middle-income countries, as there are limited studies available on this topic in these countries.

    2013-01-01

    Introduction Demineralization of the dental enamel is a finding associated with fixed orthodontic treatment. When an indirect bonding procedure is used in children and adolescents the area beneath the bracket base may be affected. Aim To evaluate if the addition of an extra layer of a hydrophilic resin, to a conventional indirect bonding protocol, can reduce the incidence of demineralization beneath the bracket base. Methods 40 patients under 18 years of age were treated with completely customized lingual appliances. Two different bonding protocols were used either with or without the application of an additional layer of hydrophilic resin. Demineralization beneath the bracket base, after de-bonding, was evaluated by standardized intra-oral photographs. Results The addition of an extra layer of a hydrophilic resin helps to reduce the number of demineralized areas beneath the bracket bases significantly (three times less). The severity of the few remaining defects were minor and without any clinical consequence. Conclusion When bonding a completely customized lingual appliance in children and adolescents, an extra layer of a hydrophilic resin should be added to the teeth. PMID:24025345

    Full Text Available Abstract Background Although young people's transition from Child and Adolescent Mental Health Services (CAMHS to Adult Mental Health Services (AMHS in England is a significant health issue for service users, commissioners and providers, there is little evidence available to guide service development. The TRACK study aims to identify factors which facilitate or impede effective transition from CAHMS to AMHS. This paper presents findings from a survey of transition protocols in Greater London. Methods A questionnaire survey (Jan-April 2005 of Greater London CAMHS to identify transition protocols and collect data on team size, structure, transition protocols, population served and referral rates to AMHS. Identified transition protocols were subjected to content analysis. Results Forty two of the 65 teams contacted (65% responded to the survey. Teams varied in type (generic/targeted/in-patient, catchment area (locality-based, wider or national and transition boundaries with AMHS. Estimated annual average number of cases considered suitable for transfer to AMHS, per CAMHS team (mean 12.3, range 0–70, SD 14.5, n = 37 was greater than the annual average number of cases actually accepted by AMHS (mean 8.3, range 0–50, SD 9.5, n = 33. In April 2005, there were 13 active and 2 draft protocols in Greater London. Protocols were largely similar in stated aims and policies, but differed in key procedural details, such as joint working between CAHMS and AMHS and whether protocols were shared at Trust or locality level. While the centrality of service users' involvement in the transition process was identified, no protocol specified how users should be prepared for transition. A major omission from protocols was procedures to ensure continuity of care for patients not accepted by AMHS. Conclusion At least 13 transition protocols were in operation in Greater London in April 2005. Not all protocols meet all requirements set by government policy. Variation in

    Full Text Available Objectives. Adolescence is associated with increased depressive symptoms and decreased aerobic exercise, yet the relationship between exercise and clinical depression among adolescents requires further examination. This study assessed the feasibility of a 12-week intervention designed to increase exercise for adolescents with depressive disorders: Will a teenager with depression exercise? Methods. Participants were 13 adolescents with depression reporting low levels of aerobic exercise. They completed a 12-week intervention (15 supervised exercise sessions and 21 independent sessions. Exercise was measured through the aerobic exercise Questionnaire, actigraphy, and heart-rate monitoring. Depression was measured with the Children’s Depression Rating Scale, Revised, and Quick Inventory of Depressive Symptomatology, Self-Report. Results. All participants who started the intervention completed the protocol, attending all supervised exercise sessions. Actigraphy verified 81% adherence to the protocol’s independent sessions. Analysis of secondary outcomes showed a significant increase in exercise levels and a significant decrease in depression severity. Initially, ten participants were overweight or obese, and three were healthy weight. After 12 weeks of exercise, the number of participants in the healthy-weight category doubled. Conclusions. Adolescents suffering from depression can complete a rigorous protocol requiring structured increases in aerobic exercise. Participants showed significant increases in exercise, and significant decreases in depressive symptoms.

    Full Text Available Abstract Background Many adolescent girls in Kenya and elsewhere face considerable risks and vulnerabilities that affect their well-being and hinder a safe, healthy, and productive transition into early adulthood. Early adolescence provides a critical window of opportunity to intervene at a time when girls are experiencing many challenges, but before those challenges have resulted in deleterious outcomes that may be irreversible. The Adolescent Girls Initiative-Kenya (AGI-K is built on these insights and designed to address these risks for young adolescent girls. The long-term goal of AGI-K is to delay childbearing for adolescent girls by improving their well-being. Intervention AGI-K comprises nested combinations of different single-sector interventions (violence prevention, education, health, and wealth creation. It will deliver interventions to over 6000 girls between the ages of 11 and 14 years in two marginalized areas of Kenya: 1 Kibera in Nairobi and 2 Wajir County in Northeastern Kenya. The program will use a combination of girl-, household- and community-level interventions. The violence prevention intervention will use community conversations and planning focused on enhancing the value of girls in the community. The educational intervention includes a cash transfer to the household conditioned on school enrollment and attendance. The health intervention is culturally relevant, age-appropriate sexual and reproductive health education delivered in a group setting once a week over the course of 2 years. Lastly, the wealth creation intervention provides savings and financial education, as well as start-up savings. Methods/Design A randomized trial will be used to compare the impact of four different packages of interventions, in order to assess if and how intervening in early adolescence improves girls’ lives after four years. The project will be evaluated using data from behavioural surveys conducted before the start of the program

    Purpose Current refeeding recommendations for adolescents hospitalized with anorexia nervosa (AN) are conservative, starting with low calories and advancing slowly to avoid refeeding syndrome. The purpose of this study was to examine weight change and clinical outcomes in hospitalized adolescents with AN on a recommended refeeding protocol. Methods Adolescents aged 13.1–20.5 years were followed during hospitalization for AN. Weight, vital signs, electrolytes, and 24-hour fluid balance were measured daily. Percent median body mass index (%MBMI) was calculated as 50th percentile BMI for age and gender. Calories were prescribed on admission and were increased every other day. Results Thirty-five subjects with a mean (SD) age of 16.2 (1.9) years participated over 16.7 (6.4) days. Calories increased from 1,205 (289) to 2,668 (387). No subjects had refeeding syndrome; 20% had low serum phosphorus. Percent MBMI increased from 80.1 (11.5) to 84.5 (9.6); overall gain was 2.10 (1.98) kg. However, 83% of subjects initially lost weight. Mean %MBMI did not increase significantly until day 8. Higher calories prescribed at baseline were significantly associated with faster weight gain (p = .003) and shorter hospital stay (p = .030) in multivariate regression models adjusted for %MBMI and lowest heart rate on admission. Conclusions Hospitalized adolescents with AN demonstrated initial weight loss and slow weight gain on a recommended refeeding protocol. Higher calorie diets instituted at admission predicted faster weight gain and shorter hospital stay. These findings support the development of more aggressive feeding strategies in adolescents hospitalized with AN. Further research is needed to identify caloric and supplementation regimens to maximize weight gain safely while avoiding refeeding syndrome. PMID:22188830

    Raising cancer awareness among adolescents has potential to increase their knowledge and confidence in identifying cancer symptoms and seeking timely medical help in adolescence and adulthood. Detecting cancer at an early stage is important because it reduces the risk of dying of some cancers and thereby contributes to improved cancer survival. Adolescents may also play an important role in increasing cancer communication within families. However, there are no randomised controlled trials (RCT) of the effectiveness of school-based educational interventions to increase adolescents' cancer awareness, and little is known about the role of adolescents in the upward diffusion of cancer knowledge to parents/carers. The aim of this study is to determine the effectiveness of a school-based educational intervention to raise adolescent and parent cancer awareness and adolescent-parent cancer communication. The Adolescent Cancer Education (ACE) study is a school-based, cluster RCT. Twenty secondary schools in the area covered by Glasgow City Council will be recruited. Special schools for adolescents whose additional needs cannot be met in mainstream education are excluded. Schools are randomised to receive a presentation delivered by a Teenage Cancer Trust educator in Autumn 2013 (intervention group) or Spring 2014 following completion of six-month follow-up measures (control group). Participants will be students recruited at the end of their first year of secondary education (S1) (age 12 to 13 years) and one parent/carer for each student, of the student's choice. The primary outcome is recognition of cancer symptoms two weeks post-intervention. Secondary outcomes are parents' cancer awareness and adolescent-parent cancer communication. Outcomes will be assessed at baseline (when adolescents are in the final term of S1), two-week, and six-month follow-up (when adolescents are in S2, age 13 to 14 years). Differences in outcomes between trial arms will be tested using

    The Interdisciplinary Orofacial Examination Protocol for Children and Adolescents (Protocolo de exploración interdisciplinaria orofacial para niños y adolescents, Barcelona, 2008) is very useful in providing a fast, initial, expedient detection of possible morphological and functional disorders, and to guide the patient toward the appropriate professionals. With this tool it is possible to detect the risk factors which can negatively affect morphological and functional harmony and guide patients toward the necessary treatment as early as possible. This Protocol, developed by 4 orthodontists, 1 ENT and 3 speech language therapists, also contributes to the unification of concepts and nomenclature used by distinct specialists, thus making professional understanding easier and more dynamic.

    It is not clear how using partial-mouth periodontal examination (PMPE) protocols affects estimates of the association between gingival bleeding (GB) and oral health-related quality of life (OHRQoL). The aim of the present study is to assess impact of different PMPEs on the association between GB and OHRQoL in 12-year-old adolescents. A total of 1,134 adolescents were evaluated for clinical and subjective variables. GB was determined by full-mouth examination (FME) of six sites (disto-buccal [DB], mid-buccal [B], mesio-buccal [MB], disto-lingual [DL], mid-lingual, and mesio-lingual [ML]) and different PMPEs were calculated using a 15% cut-off point: 1) full-mouth (MB-B-DB/MB-B-DL); 2) two diagonal quadrants (six sites/MB-B-DB/MB-B-DL); 3) two randomly selected half-mouth quadrants (six sites/MB-B-DB/ MB-B-DL/MB-DB-ML-DL); and 4) the community periodontal index. OHRQoL was assessed using the Child Perceptions Questionnaire (CPQ 11-14 ). Adjusted negative binomial regression models were used to calculate the rate ratio of CPQ 11-14 scores for each PMPE. Adolescents with GB showed significantly poorer OHRQoL than their counterparts when FME was used. In contrast, more than half of PMPE protocols did not detect significant associations between GB and CPQ 11-14 scores in the adjusted analysis. Using PMPE to assess GB in adolescents significantly affects associations with OHRQoL outcomes, depending on the protocol used. PMPEs that evaluated MB-B-DL sites of randomly selected half-mouth quadrants (1 or 2 and 3 or 4) achieved results closer to those obtained with FME.

    Human papillomavirus (HPV)-related cancers are a significant burden on the US health care system that can be prevented through adolescent HPV vaccination. Despite guidelines recommending vaccination, coverage among US adolescents is suboptimal particularly among underserved patients (uninsured, low income, racial, and ethnic minorities) seen in safety-net health care settings. Many parents are ambivalent about the vaccine and delay making a decision or talking with a provider about it. Self-persuasion-generating one's own arguments for a health behavior-may be particularly effective for parents who are undecided or not motivated to make a vaccine decision. Through a 3-stage mixed-methods protocol, we will identify an optimal and feasible self-persuasion intervention strategy to promote adolescent HPV vaccination in safety-net clinics. In Stage 1, we will define content for a tablet-based self-persuasion app by characterizing (1) parents' self-generated arguments through cognitive interviews conducted with parents (n=50) of patients and (2) parent-provider HPV vaccine discussions through audio recordings of clinic visits (n=50). In Stage 2, we will compare the effects of the four self-persuasion intervention conditions that vary by cognitive processing level (parents verbalize vs listen to arguments) and choice of argument topics (parents choose vs are assigned topics) on parental vaccine intentions in a 2 × 2 factorial design randomized controlled trial (n=160). This proof-of-concept trial design will identify which intervention condition is optimal by quantitatively examining basic self-persuasion mechanisms (cognitive processing and choice) and qualitatively exploring parent experiences with intervention tasks. In Stage 3, we will conduct a pilot trial (n=90) in the safety-net clinics to assess feasibility of the optimal intervention condition identified in Stage 2. We will also assess its impact on parent-provider discussions. This paper describes the study

    Optimal psychological development is dependent upon a complex interplay between individual and situational factors. Investigating the development of these factors in adolescence will help to improve understanding of emotional vulnerability and resilience. The CogBIAS longitudinal study (CogBIAS-L-S) aims to combine cognitive and genetic approaches to investigate risk and protective factors associated with the development of mood and impulsivity-related outcomes in an adolescent sample. CogBIAS-L-S is a three-wave longitudinal study of typically developing adolescents conducted over 4 years, with data collection at age 12, 14 and 16. At each wave participants will undergo multiple assessments including a range of selective cognitive processing tasks (e.g. attention bias, interpretation bias, memory bias) and psychological self-report measures (e.g. anxiety, depression, resilience). Saliva samples will also be collected at the baseline assessment for genetic analyses. Multilevel statistical analyses will be performed to investigate the developmental trajectory of cognitive biases on psychological functioning, as well as the influence of genetic moderation on these relationships. CogBIAS-L-S represents the first longitudinal study to assess multiple cognitive biases across adolescent development and the largest study of its kind to collect genetic data. It therefore provides a unique opportunity to understand how genes and the environment influence the development and maintenance of cognitive biases and provide insight into risk and protective factors that may be key targets for intervention.

    Early marriages, pregnancies and births are the major cause of school drop-out among adolescent girls in sub-Saharan Africa. Birth complications are also one of the leading causes of death among adolescent girls. This paper outlines a protocol for a cost-benefit analysis (CBA) and an extended cost-effectiveness analysis (ECEA) of a comprehensive adolescent pregnancy prevention program in Zambia. It aims to estimate the expected costs, monetary and non-monetary benefits associated with health-related and non-health outcomes, as well as their distribution across populations with different standards of living. The study will be conducted alongside a cluster-randomized controlled trial, which is testing the hypothesis that economic support with or without community dialogue is an effective strategy for reducing adolescent childbearing rates. The CBA will estimate net benefits by comparing total costs with monetary benefits of health-related and non-health outcomes for each intervention package. The ECEA will estimate the costs of the intervention packages per unit health and non-health gain stratified by the standards of living. Cost data include program implementation costs, healthcare costs (i.e. costs associated with adolescent pregnancy and birth complications such as low birth weight, pre-term birth, eclampsia, medical abortion procedures and post-abortion complications) and costs of education and participation in community and youth club meetings. Monetary benefits are returns to education and averted healthcare costs. For the ECEA, health gains include reduced rate of adolescent childbirths and non-health gains include averted out-of-pocket expenditure and financial risk protection. The economic evaluations will be conducted from program and societal perspectives. While the planned intervention is both comprehensive and expensive, it has the potential to produce substantial short-term and long-term health and non-health benefits. These benefits should be

    Full Text Available Abstract Background Most skin cancers are preventable by encouraging consistent use of sun protective behaviour. In Australia, adolescents have high levels of knowledge and awareness of the risks of skin cancer but exhibit significantly lower sun protection behaviours than adults. There is limited research aimed at understanding why people do or do not engage in sun protective behaviour, and an associated absence of theory-based interventions to improve sun safe behaviour. This paper presents the study protocol for a school-based intervention which aims to improve the sun safe behaviour of adolescents. Methods/design Approximately 400 adolescents (aged 12-17 years will be recruited through Queensland, Australia public and private schools and randomized to the intervention (n = 200 or 'wait-list' control group (n = 200. The intervention focuses on encouraging supportive sun protective attitudes and beliefs, fostering perceptions of normative support for sun protection behaviour, and increasing perceptions of control/self-efficacy over using sun protection. It will be delivered during three × one hour sessions over a three week period from a trained facilitator during class time. Data will be collected one week pre-intervention (Time 1, and at one week (Time 2 and four weeks (Time 3 post-intervention. Primary outcomes are intentions to sun protect and sun protection behaviour. Secondary outcomes include attitudes toward performing sun protective behaviours (i.e., attitudes, perceptions of normative support to sun protect (i.e., subjective norms, group norms, and image norms, and perceived control over performing sun protective behaviours (i.e., perceived behavioural control. Discussion The study will provide valuable information about the effectiveness of the intervention in improving the sun protective behaviour of adolescents.

    Policies internationally endorse the recovery paradigm as the appropriate foundation for youth mental health services. However, given that this paradigm is grounded in the views of adults with severe mental illness, applicability to youth services and relevance to young people is uncertain, particularly as little is known about young people's views. A comprehensive understanding of the experiences and expectations of young people is critical to developing youth mental health services that are acceptable, accessible, effective and relevant. To inform development of policy and youth services, the study described in this protocol aims to develop a comprehensive account of the experiences and expectations of 12-17 year olds as they encounter mental disorders and transition through specialist mental health services. Data will be analysed to model recovery from the adolescents' perspective. This grounded theory study will use quantitative and qualitative data collected in interviews with 12-17 year olds engaged with specialist Child/Youth Mental Health Service in Queensland, Australia. Interviews will explore adolescents' expectations and experiences of mental disorder, and of services, as they transition through specialist mental health services, including the meaning of their experiences and ideas of 'recovery' and how their experiences and expectations are shaped. Data collection and analysis will use grounded theory methods. Adolescents' experiences will be presented as a mid-range theory. The research will provide tangible recommendations for youth-focused mental health policy and practice. Findings will be disseminated within academic literature and beyond to participants, health professionals, mental health advocacy groups and policy and decision makers via publications, research summaries, conferences and workshops targeting different audiences. Ethical and research governance approvals have been obtained from relevant Human Research Ethics committees and all

    Full Text Available Abstract Background The prevalence of childhood obesity is increasing at a high rate in Brazil, making prevention a health priority. Schools are the central focus of interventions aiming the prevention and treatment of childhood obesity, however, randomized trials and cohort studies have not yet provided clear evidence of strategies to reduce prevalence of obesity. The aim of this study is to present a protocol to evaluate the efficacy of combining school and household level interventions to reduce excessive weight gain among students. Methods The intervention target fifth and sixth graders from 18 public schools (9 interventions and 9 controls in the municipality of Duque de Caxias, metropolitan area of Rio de Janeiro, Brazil. A sample size of 2500 students will be evaluated at school for their weight status and those from the intervention group who are overweight or obese will be followed monthly at home by community health agents. Demographic, socioeconomic, anthropometric, eating behavior and food consumption data will be collected at school using a standardized questionnaire programmed in personal digital assistant. At school, all students from the intervention group will be encouraged to change eating habits and food consumption and to increase physical activity and reducing sedentary behavior. Discussion This study will provide evidence whether integration of school with primary health care can prevent excessive weight gain among adolescents. Positive results will inform a sustainable strategy to be disseminated in the health care system in Brazil. Trial registration ClinicalTrials.gov, NCT02711488 . Date of registration: March 11, 2016.

    Current research shows that overall numbers for cannabis use among adolescents and young adults dropped in recent years. However, this trend is much less pronounced in continuous cannabis use. With regard to the heightened risk for detrimental health- and development-related outcomes, adolescents and young adults with continuous cannabis use need special attention. The health services structure for adolescents and young adults with substance related problems in Germany, is multifaceted, because different communal, medical and judicial agencies are involved. This results in a rather decentralized organizational structure of the help system. This and further system-inherent characteristics make the threshold for young cannabis users rather high. Because of this, there is a need to establish evidence-based low-threshold help options for young cannabis users, which can be easily disseminated. Therefore, a training programme for young cannabis users (age 14-21) was developed in the "CAN Stop" project. Within the project, we seek to implement and evaluate the training programme within different institutions of the help system. The evaluation is sensitive to the different help systems and their specific prerequisites. Moreover, within this study, we also test the practicability of a training provision through laypersons. The CAN Stop study is a four-armed randomized wait-list controlled trial. The four arms are needed for the different help system settings, in which the CAN Stop training programme is evaluated: (a) the drug addiction aid and youth welfare system, (b) the out-patient medical system, (c) the in-patient medical system and (d) prisons for juvenile offenders. Data are collected at three points, before and after the training or a treatment as usual, and six months after the end of either intervention. The CAN Stop study is expected to provide an evidence-based programme for young cannabis users seeking to reduce or quit their cannabis use. Moreover, we seek to

    Prior studies addressing the impacts of regular physical activity or sedentary habits on the immune system have been conducted in adults and laboratory settings. Thus, it is practically unknown how a healthy active lifestyle could affect low-grade inflammation processes, infections or allergies in young persons. The AFINOS Study was designed to determine the relationship between the regular physical activity levels of adolescents and overweight, infection, and allergies along with the presence of metabolic and immunological biomarkers of a deteriorated health status. A further objective of the AFINOS Study is to assess the health status and lifestyle habits of an adolescent population in an effort to identify any protective factors that could be used as preventive measures, since many chronic diseases and their associated co-morbidities often persist from adolescence into adulthood. This study was conducted as three separate sub-studies in three different populations as follows: (a) Study 1 was performed on a population sample of adolescents; (b) Study 2 on the adolescents' parents; and (c) Study 3 on a subset of the adolescents from Study 1. Study 1 assessed health and lifestyle indicators through a questionnaire administered to a representative sample of adolescents from the Madrid Region (n = 2400) aged 13 to 16 years. In Study 2, the parents of the teenagers participating in Study 1 were required to fill out a questionnaire. Finally in Study 3, body composition, physical activity, health-related physical fitness, and blood measurements were determined in a subset (n = 200) of the individuals included in Study 1. This paper describes the rationale, design, and methodologies used in the AFINOS Study. This multidisciplinary, multicenter study seeks to evaluate several aspects of existing relationships between routine physical activity/sedentary behaviour and several health status markers, specifically those related to the immune system.

    Imaging plays a key role in adolescent idiopathic scoliosis (AIS) to determine the prognosis and accordingly define the best therapeutic strategy to follow. Conventional radiographs with ionizing radiation have been associated with 1-2 % increased lifetime risk of developing cancer in children, and physicians, therefore, need a sensitive but harmless way to explore patients at risk, according to the "as low as reasonably achievable" concept. The EOS system (EOS imaging, Paris, France) is available in routine clinical use since 2007, and allows 3D reconstructions of the trunk in standing position with significant radiation reduction. With recent technical advances, further dose reduction can be obtained, but at the cost of image quality that might alter the reliability of 3D reconstructions. The aim of the present study was to analyze the reproducibility of a "microdose" protocol, and evaluate its use in clinical practice. 32 consecutive patients followed for AIS were prospectively included. Biplanar radiographs were obtained with the EOS system according to the new microdose protocol. From the microdose images obtained, three experienced operators performed 3D reconstructions, two times for each subject in a random order (total, 192 reconstructions). The intraoperator repeatability and interoperator reproducibility were evaluated, as recommended by the International Organization for Standardization, for the most clinically relevant 3D radiological parameters. The identification of the required anatomical landmarks for the "fast spine" reconstruction process was possible in all cases. None of the patients required a second acquisition for 3D analysis. Mean time for reconstruction was 5 ± 2 min. The intraoperator repeatability was better than interoperator reproducibility for all parameters, with values ranging between 3° and 8° for frontal and sagittal spinal parameters, and between 1° and 8° for pelvic measurements. The agreement was very good for all clinical

    Full Text Available Abstract Background Substance use is highly prevalent among Dutch adolescents. The Healthy School and Drugs program is a nationally implemented school-based prevention program aimed at reducing early and excessive substance use among adolescents. Although the program's effectiveness was tested in a quasi-experimental design before, many program changes were made afterwards. The present study, therefore, aims to test the effects of this widely used, renewed universal prevention program. Methods/Design A randomized clustered trial will be conducted among 3,784 adolescents of 23 secondary schools in The Netherlands. The trial has three conditions; two intervention conditions (i.e., e-learning and integral and a control condition. The e-learning condition consists of three digital learning modules (i.e., about alcohol, tobacco, and marijuana that are sequentially offered over the course of three school years (i.e., grade 1, grade 2, and grade 3. The integral condition consists of parental participation in a parental meeting on substance use, regulation of substance use, and monitoring and counseling of students' substance use at school, over and above the three digital modules. The control condition is characterized as business as usual. Participating schools were randomly assigned to either an intervention or control condition. Participants filled out a digital questionnaire at baseline and will fill out the same questionnaire three more times at follow-up measurements (8, 20, and 32 months after baseline. Outcome variables included in the questionnaire are the percentage of binge drinking (more than five drinks per occasion, the average weekly number of drinks, and the percentage of adolescents who ever drunk a glass of alcohol and the percentage of adolescents who ever smoked a cigarette or a joint respectively for tobacco and marijuana.

    To assess the efficacy of cognitive behavioral therapy (CBT) for managing adolescent ADHD. A total of 68 adolescents with ADHD and associated psychiatric comorbidities completed a manualized CBT treatment protocol. The intervention used in the study was a downward extension of the Safren et al. program for adults with ADHD who have symptoms unresolved by medication. Outcome variables consisted of narrow band (ADHD) and broadband (e.g., mood, anxiety, conduct) symptom measures (Behavior Assessment System for Children-2nd edition and ADHD-Rating Scales) as well as functioning measures (parent/teacher ratings and several ecologically real-world measures). Treatment effects emerged on the medication dosage, parent rating of pharmacotherapy adherence, adolescent self-report of personal adjustment (e.g., self-esteem), parent and teacher ratings of inattentive symptoms, school attendance, school tardiness, parent report of peer, family and academic functioning and teacher report of adolescent relationship with teacher, academic progress, and adolescent self-esteem. Adolescents with ADHD with oppositional defiant disorder were rated by parents and teachers as benefiting less from the CBT intervention. Adolescents with ADHD and comorbid anxiety/depression were rated by parents and teachers as benefiting more from the CBT intervention. A downward extension of an empirically validated adult ADHD CBT protocol can benefit some adolescents with ADHD. © 2012 SAGE Publications.

    Maintaining contact with and collecting outcome data from adolescent study participants can present a significant challenge for researchers conducting longitudinal studies. Establishing an organized and effective protocol for participant follow-up is crucial to reduce attrition and maintain high retention rates. This paper describes our methods in using and adapting the evidence-based Engagement, Verification, Maintenance, and Confirmation (EVMC) model to follow up with adolescents 6 and 12 months after implementation of a health program. It extends previous research by focusing on two key modifications to the model: (1) the central role of cell phones and texting to maintain contact with study participants throughout the EVMC process and, (2) use of responsive two-way communication between staff and participants and flexible administration modes and methods in the confirmation phase to ensure that busy teens not only respond to contacts, but also complete data collection. These strategies have resulted in high overall retention rates (87-91%) with adolescent study participants at each follow-up data collection point without the utilization of other, more involved tracking measures. The methods and findings presented may be valuable for other researchers with limited resources planning for or engaged in collecting follow-up outcome data from adolescents enrolled in longitudinal studies.

    Childhood maltreatment represents an important public health concern, as it is often associated with a host of negative outcomes across development. In recent years, researchers have begun to examine the link between negative health-related behaviors and history of childhood maltreatment. The current study considers the relationship between history of childhood maltreatment and sleep disturbances in adolescence. Further, the role of psychological distress is considered as an explanatory link between childhood maltreatment and adolescent sleep disturbances. The current study is a secondary analysis using a subsample (N=73) of child welfare-involved youth who participated in the initial and 2-year time-point of the Maltreatment and Adolescent Pathways (MAP) Longitudinal Study on the variables of interest. Youth reported on lifetime maltreatment experiences, psychological distress, and sleep disturbances, in addition to the other measures administered as part of the larger MAP study protocol. More severe childhood maltreatment was related to increased sleep disturbances during adolescence, and psychological distress was a significant mediator of the childhood maltreatment-adolescent sleep disturbance association. The results demonstrate that a history of childhood maltreatment represents a risk factor for sleep disturbances in adolescence. The findings highlight the importance of inquiring about health-related behaviors in child welfare youth and the need to promote psychological well-being within this population.

    Growing evidence points for the need to publish study protocols in the health field. To observe whether the growing interest in publishing study protocols in the broader health field has been translated into increased publications of rehabilitation study protocols. Observational study using publication data and its indexation in PubMed. Not applicable. Not applicable. PubMed was searched with appropriate combinations of Medical Subject Headings up to December 2014. The effective presence of study protocols was manually screened. Regression models analyzed the yearly growth of publications. Two-sample Z-tests analyzed whether the proportion of Systematic Reviews (SRs) and Randomized Controlled Trials (RCTs) among study protocols differed from that of the same designs for the broader rehabilitation research. Up to December 2014, 746 publications of rehabilitation study protocols were identified, with an exponential growth since 2005 (r2=0.981; p<0.001). RCT protocols were the most common among rehabilitation study protocols (83%), while RCTs were significantly more prevalent among study protocols than among the broader rehabilitation research (83% vs. 35.8%; p<0.001). For SRs, the picture was reversed: significantly less common among study protocols (2.8% vs. 9.3%; p<0.001). Funding was more often reported by rehabilitation study protocols than the broader rehabilitation research (90% vs. 53.1%; p<0.001). Rehabilitation journals published a significantly lower share of rehabilitation study protocols than they did for the broader rehabilitation research (1.8% vs.16.7%; p<0.001). Identifying the reasons for these discrepancies and reverting unwarranted disparities (e.g. low rate of publication for rehabilitation SR protocols) are likely new avenues for rehabilitation research and its publication. SRs, particularly those aggregating RCT results, are considered the best standard of evidence to guide rehabilitation clinical practice; however, that standard can be improved

    Published experimental sleep manipulation protocols for adolescents have been limited to the summer, limiting causal conclusions about how short sleep affects them on school nights, when they are most likely to restrict their sleep. This study assesses the feasibility and emotional impact of a school-night sleep manipulation protocol to test the effects of lengthening sleep in habitually short-sleeping adolescents. High school students aged 14-18 years who habitually slept 5-7 hours on school nights participated in a 5-week experimental sleep manipulation protocol. Participants completed a baseline week followed in randomized counterbalanced order by two experimental conditions lasting 2 weeks each: prescribed habitual sleep (HAB; sleep time set to match baseline) and sleep extension (EXT; 1.5-hour increase in time in bed from HAB). All sleep was obtained at home, monitored with actigraphy. Data on adherence, protocol acceptability, mood and behavior were collected at the end of each condition. Seventy-six adolescents enrolled in the study, with 54 retained through all 5 weeks. Compared to HAB, during EXT, participants averaged an additional 72.6 minutes/night of sleep (p sleep manipulation protocol can be feasibly implemented which directly tests the potential protective effects of lengthening sleep. Many short-sleeping adolescents would benefit emotionally from sleeping longer, supporting public health efforts to promote adolescent sleep on school nights. © Sleep Research Society 2017.

    The rapid increase in mobile phone use in young people has generated concern about possible health effects of exposure to radiofrequency (RF) and extremely low frequency (ELF) electromagnetic fields (EMF). MOBI-Kids, a multinational case–control study, investigates the potential effects of childhood and adolescent exposure to EMF from mobile communications technologies on brain tumor risk in 14 countries. The study, which aims to include approximately 1,000 brain tumor cases aged 10–24 years and two individually matched controls for each case, follows a common protocol and builds upon the methodological experience of the INTERPHONE study. The design and conduct of a study on EMF exposure and brain tumor risk in young people in a large number of countries is complex and poses methodological challenges. This manuscript discusses the design of MOBI-Kids and describes the challenges and approaches chosen to address them, including: (1) the choice of controls operated for suspected appendicitis, to reduce potential selection bias related to low response rates among population controls; (2) investigating a young study population spanning a relatively wide age range; (3) conducting a large, multinational epidemiological study, while adhering to increasingly stricter ethics requirements; (4) investigating a rare and potentially fatal disease; and (5) assessing exposure to EMF from communication technologies. Our experience in thus far developing and implementing the study protocol indicates that MOBI-Kids is feasible and will generate results that will contribute to the understanding of potential brain tumor risks associated with use of mobile phones and other wireless communications technologies among young people.

    Various regulations and guidelines stipulate the importance of involving adolescents in decision-making concerning research participation. Several studies have shown that in the context of pediatric oncology this involvement is difficult to achieve due to emotional stress, the complexity of research protocols and limited time. Still, up to 80% of adolescents with cancer enter onto a trial during their illness. The aim of this study was to determine clinicians' views and attitudes towards enrolling adolescents in research, considering the difficulties surrounding their involvement in decision-making. A qualitative multicenter study was performed, using in-depth semi-structured interviews on the informed consent process with 15 pediatric hemato-oncologists. Four central themes emerged that characterize clinicians' attitudes towards involving adolescents in the decision-making process: (1) clinicians regard most adolescents as not capable of participating meaningfully in discussions regarding research; (2) clinicians do not always provide adolescents with all information; (3) proxy consent from parents is obtained and is deemed sufficient; (4) clinician-investigator integrity: clinicians judge research protocols as not being harmful and even in the best interest of the adolescent. Clinicians justify not involving adolescents in research discussions by referring to best interest arguments (adolescents' incompetence, proxy consent, and investigator integrity), although this is not in line with legal regulations and ethical guidelines.

    Background Binge eating disorder is a prevalent adolescent disorder, associated with increased eating disorder and general psychopathology as well as an increased risk for overweight and obesity. As opposed to binge eating disorder in adults, there is a lack of validated psychological treatments for this condition in adolescents. The goal of this research project is therefore to determine the efficacy of age-adapted cognitive-behavioral therapy in adolescents with binge eating disorder ? the ...

    Over 1.6 million adolescents in the United States meet criteria for substance use disorders (SUDs). While there are promising treatments for SUDs, adolescents respond to these treatments differentially in part based on the setting in which treatments are delivered. One way to address such individualized response to treatment is through the development of adaptive interventions (AIs): sequences of decision rules for altering treatment based on an individual's needs. This protocol describes a project with the overarching goal of beginning the development of AIs that provide recommendations for altering the setting of an adolescent's substance use treatment. This project has three discrete aims: (1) explore the views of various stakeholders (parents, providers, policymakers, and researchers) on deciding the setting of substance use treatment for an adolescent based on individualized need, (2) generate hypotheses concerning candidate AIs, and (3) compare the relative effectiveness among candidate AIs and non-adaptive interventions commonly used in everyday practice. This project uses a mixed-methods approach. First, we will conduct an iterative stakeholder engagement process, using RAND's ExpertLens online system, to assess the importance of considering specific individual needs and clinical outcomes when deciding the setting for an adolescent's substance use treatment. Second, we will use results from the stakeholder engagement process to analyze an observational longitudinal data set of 15,656 adolescents in substance use treatment, supported by the Substance Abuse and Mental Health Services Administration, using the Global Appraisal of Individual Needs questionnaire. We will utilize methods based on Q-learning regression to generate hypotheses about candidate AIs. Third, we will use robust statistical methods that aim to appropriately handle casemix adjustment on a large number of covariates (marginal structural modeling and inverse probability of treatment weights

    Borderline personality disorder (BPD) is being increasingly recognized by clinicians working with adolescents, and the reliability and validity of the diagnosis have been established in the adolescent population. Adolescence is known to be a period of high risk for BPD development as most patients identify the onset of their symptoms to be in the adolescent period. As with other mental health disorders, personality disorder, are thought to result from the interaction between biological and environmental factors. Functional neuroimaging studies are reporting an increasing amount of data on abnormal neuronal functions in BPD adult patients. However, no functional neuroimaging studies have been conducted in adolescents with BPD.Objectives This pilot project aims to evaluate the feasibility of a functional magnetic resonance imaging (fMRI) study coupled with clinical and psychological measures in adolescent girls with a diagnosis of BPD. It also aims to identify neuronal regions of interest (ROI) for the study of BPD in adolescent girls.Method Six female adolescents meeting DSM-IV criteria for BPD and 6 female adolescents without psychiatric disorder were recruited. Both groups were evaluated for BPD symptoms, depressive symptoms, impulsivity, affective lability, and other potential psychiatric comorbidities. We used fMRI to compare patterns of regional brain activation between these two groups as they viewed 20 positive, 20 negative and 20 neutral emotion-inducing pictures, which were presented in random order.Results Participants were recruited over a period of 22 months. The protocol was well tolerated by participants. Mean age of the BPD group and control group was 15.8 ± 0.9 years-old and 15.5 ± 1.2 years-old respectively. Psychiatric comorbidity and use of medication was common among participants in the BPD group. This group showed higher impulsivity and affective lability scores. For the fMRI task, BPD patients demonstrated greater differences in activation

    In Europe, the number of females exhibiting oppositional defiant disorder (ODD) and conduct disorder (CD) is growing. Many of these females live in youth welfare institutions. Consequently, there is a great need for evidence-based interventions within youth welfare settings. A recently developed approach targeting the specific needs of girls with ODD and CD in residential care is START NOW. The aim of this group-based behavioural skills training programme is to specifically enhance emotional regulation capacities to enable females with CD or ODD to appropriately deal with daily-life demands. It is intended to enhance psychosocial adjustment and well-being as well as reduce oppositional and aggressive behaviour. We present the study protocol (version 4.1; 10 February 2016) of the FemNAT-CD intervention trial titled 'Group-Based Treatment of Adolescent Female Conduct Disorders: The Central Role of Emotion Regulation'. The study is a prospective, confirmatory, cluster-randomised, parallel-group, multi-centre, randomised controlled trial with 128 institutionalised female adolescents who fulfil the diagnostic criteria of ODD and/or CD. Institutions/wards will be randomised either to provide the 12-week skills training as an add-on intervention or to provide treatment as usual. Once the first cycle is completed, each institution will run a second cycle with the opposite condition. Primary endpoints are the pre-post change in number of CD/ODD symptoms as assessed by a standardised, semi-structured psychiatric interview (Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime, CD/ODD section) between baseline and the end of intervention, as well as between baseline and a 3-month follow-up point. Secondary objectives include pre-post change in CD/ODD-related outcome measures, most notably emotional regulation on a behavioural and neurobiological level after completion of START NOW compared with treatment as usual.

    Family-based treatment is an efficacious outpatient intervention for medically stable adolescents with anorexia nervosa. Previous research suggests family-based treatment may be more effective for some families when parents and adolescents attend separate therapy sessions compared to conjoint sessions. Our service developed a novel separated model of family-based treatment, parent-focused treatment, and is undertaking a randomised controlled trial to compare parent-focused treatment to conjoint family-based treatment. This randomised controlled trial will recruit 100 adolescents aged 12-18 years with DSM-IV anorexia nervosa or eating disorder not otherwise specified (anorexia nervosa type). The trial commenced in 2010 and is expected to be completed in 2015. Participants are recruited from the Royal Children's Hospital Eating Disorders Program, Melbourne, Australia. Following a multidisciplinary intake assessment, eligible families who provide written informed consent are randomly allocated to either parent-focused treatment or conjoint family-based treatment. In parent-focused treatment, the adolescent sees a clinical nurse consultant and the parents see a trained mental health clinician. In conjoint family-based treatment, the whole family attends sessions with the mental health clinician. Both groups receive 18 treatment sessions over 6 months and regular medical monitoring by a paediatrician. The primary outcome is remission at end of treatment and 6 and 12 month follow up, with remission defined as being ≥ 95% expected body weight and having an eating disorder symptom score within one standard deviation of community norms. The secondary outcomes include partial remission and changes in eating pathology, depressive symptoms and self-esteem. Moderating and mediating factors will also be explored. This will be first randomised controlled trial of a parent-focused model of family-based treatment of adolescent anorexia nervosa. If found to be efficacious, parent

The aim of the present study is to describe the characteristic clinical features of adolescents with DSH according to our local context (Lisbon, Portugal, using easily available information from clinical settings. A case control study was constructed from a sample of 100 adolescents (aged 12 to 21 years. The sample was divided into two groups: adolescents with and without DSH. Case files were examined and data was completed by clinical interviews. Demographic, psychosocial, and psychopathological data were assessed and compared. Ninety-eight subjects completed the protocol. The DSH group was associated with the following: suicidal ideation or suicidal behavior as consultation motive, emergency room referral, previous follow-up attempts, suicidal ideation, psychosocial difficulties, or lack of therapeutic goals. There was a nonsignificant trend towards diagnosis of depression in the DSH group. These results reflect our clinical practice with adolescents and add data about teenagers who self-harm to the literature. Prevention and early recognition of DSH (and frequently associated depression in adolescents are essential and could be life-saving measures. An integrated approach, which takes into account psychosocial difficulties, family dysfunction, and negative expectations, seems to be of great importance.Keywords: deliberate self-harm, suicide, adolescents, suicide risk, case control

    Obesity is not only a highly prevalent disease but also poses a considerable burden on children and their families. Evidence is increasing that a lack of self-regulation skills may play a role in the etiology and maintenance of obesity. Our goal with this currently ongoing trial is to examine whether training that focuses on the enhancement of self-regulation skills may increase the sustainability of a complex lifestyle intervention. In a multicenter, prospective, parallel group, randomized controlled superiority trial, 226 obese children and adolescents aged 8 to 16 years will be allocated either to a newly developed computer-training program to improve their self-regulation abilities or to a placebo control group. Randomization occurs centrally and blockwise at a 1:1 allocation ratio for each center. This study is performed in pediatric inpatient rehabilitation facilities specialized in the treatment of obesity. Observer-blind assessments of outcome variables take place at four times: at the beginning of the rehabilitation (pre), at the end of the training in the rehabilitation (post), and 6 and 12 months post-rehabilitation intervention. The primary outcome is the course of BMI-SDS over 1 year after the end of the inpatient rehabilitation. Secondary endpoints are the self-regulation skills. In addition, health-related quality of life, and snack intake will be analyzed. The computer-based training programs might be a feasible and attractive tool to increase the sustainability of the weight loss reached during inpatient rehabilitation. The present study protocol was registered on 13 July 2015 at German Clinical Trials Register: DRKS00007879 .

    Binge eating disorder is a prevalent adolescent disorder, associated with increased eating disorder and general psychopathology as well as an increased risk for overweight and obesity. As opposed to binge eating disorder in adults, there is a lack of validated psychological treatments for this condition in adolescents. The goal of this research project is therefore to determine the efficacy of age-adapted cognitive-behavioral therapy in adolescents with binge eating disorder - the gold standard treatment for adults with binge eating disorder. In a single-center efficacy trial, 60 12- to 20-year-old adolescents meeting diagnostic criteria of binge eating disorder (full-syndrome or subthreshold) according to the Diagnostic and Statistical Manual of Mental Disorders 4th or 5th Edition, will be centrally randomized to 4 months of cognitive-behavioral therapy (n = 30) or a waiting-list control condition (n = 30). Using an observer-blind design, patients are assessed at baseline, mid-treatment, post-treatment, and at 6- and 12-month follow-ups after the end of treatment. In 20 individual outpatient sessions, cognitive-behavioral therapy for adolescents focuses on eating behavior, body image, and stress; parents receive psychoeducation on these topics. Primary endpoint is the number of episodes with binge eating over the previous 28 days at post-treatment using a state-of-the art clinical interview. Secondary outcome measures address the specific eating disorder psychopathology, general psychopathology, mental comorbidity, self-esteem, quality of life, and body weight. This trial will allow us to determine the short- and long-term efficacy of cognitive-behavioral therapy in adolescent binge eating disorder, to determine cost-effectiveness, and to identify predictors of treatment outcome. Evidence will be gathered regarding whether this treatment will help to prevent excessive weight gain. If efficacy can be demonstrated, the results from this trial will enhance

    Full Text Available Background: Monitored physical activities in patients with adolescent idiopathic scoliosis (AIS have been shown to improve physical performance, endurance and cardiopulmonary function and may be assessed by the 6-min walk test (6MWT. We aimed to evaluate the long-term results of the 6MWT after a rehabilitation protocol employed before surgical correction for AIS. Methods: This prospective randomized clinical trial studied the impact of a 4-month pre-operative physical rehabilitation protocol on post-operative cardiopulmonary function and physical endurance, by using the 6MWT, in patients with AIS submitted to surgical correction, comparing them to matched controls without physical rehabilitation. Studied variables were heart and respiratory rate, systolic and diastolic blood pressure, peripheral blood oxygen saturation, Borg score, and distance walked. Patients were assessed at baseline, after 4 months of rehabilitation, and 3, 6 and 12 months post-operatively. Results: A total of 50 patients with AIS were included in the study and allocated blindly, by simple randomization, into either one of the two groups, with 25 patients each: study group (pre-operative physical rehabilitation and control group. The physical rehabilitation protocol promoted significant progressive improvement in heart and respiratory rate, peripheral blood oxygen saturation, distance walked, and level of effort assessed by the Borg scale after surgery. Conclusions: Post-surgical recovery, evaluated by 6MWT, was significantly better in patients who underwent a 4-month pre-operative physical rehabilitation protocol.

    An estimated one billion children experience child abuse each year, with the highest rates in low- and middle-income countries. The Sinovuyo Teen programme is part of Parenting for Lifelong Health, a WHO/UNICEF initiative to develop and test violence-prevention programmes for implementation in low-resource contexts. The objectives of this parenting support programme are to prevent the abuse of adolescents, improve parenting and reduce adolescent behavioural problems. This trial aims to evaluate the effectiveness of Sinovuyo Teen compared to an attention-control group of a water hygiene programme. This is a pragmatic cluster randomised controlled trial, with stratified randomisation of 37 settlements (rural and peri-urban) with 40 study clusters in the Eastern Cape of South Africa. Settlements receive either a 14-session parenting support programme or a 1-day water hygiene programme. The primary outcomes are child abuse and parenting practices, and secondary outcomes include adolescent behavioural problems, mental health and social support. Concurrent process evaluation and qualitative research are conducted. Outcomes are reported by both primary caregivers and adolescents. Brief follow-up measures are collected immediately after the intervention, and full follow-up measures collected at 3-8 months post-intervention. A 15-24-month follow-up is planned, but this will depend on the financial and practical feasibility given delays related to high levels of ongoing civil and political violence in the research sites. This is the first known trial of a parenting programme to prevent abuse of adolescents in a low- or middle-income country. The study will also examine potential mediating pathways and moderating factors. Pan-African Clinical Trials Registry PACTR201507001119966. Registered on 27 April 2015.

    The Adolescent Medicine Trials Network Protocol 113 (ATN113) is an open-label, multisite demonstration project and Phase II safety study of human immunodeficiency virus (HIV) preexposure prophylaxis with 15- to 17-year-old young men who have sex with men that requires adolescent consent for participation. The purpose of this study was to examine factors related to the process by which Institutional Review Boards (IRBs) and researchers made decisions regarding whether to approve and implement ATN113 so as to inform future biomedical HIV prevention research with high-risk adolescent populations. Participants included 17 researchers at 13 sites in 12 states considering ATN113 implementation. Qualitative descriptive methods were used. Data sources included interviews and documents generated during the initiation process. A common process for initiating ATN113 emerged, and informants described how they identified and addressed practical, ethical, and legal challenges that arose. Informants described the process as responding to the protocol, preparing for IRB submission, abstaining from or proceeding with submission, responding to IRB concerns, and reacting to the outcomes. A complex array of factors impacting approval and implementation were identified, and ATN113 was ultimately implemented in seven of 13 sites. Informants also reflected on lessons learned that may help inform future biomedical HIV prevention research with high-risk adolescent populations. The results illustrate factors for consideration in determining whether to implement such trials, demonstrate that such protocols have the potential to be approved, and highlight a need for clearer standards regarding biomedical HIV prevention research with high-risk adolescent populations.

    Intolerance of the esophageal manometry catheter may prolong high-resolution manometry (HRM) studies and increase patient distress. We assessed the impact of obtaining the landmark phase at the end of the study when the patient has acclimatized to the HRM catheter. 366 patients (mean age 55.4 ± 0.8 years, 62.0% female) undergoing esophageal HRM over a 1-year period were studied. The standard protocol consisted of the landmark phase, 10 5 mL water swallows 20-30 s apart, and multiple rapid swallows where 4-6 2 mL swallows were administered in rapid succession. The modified protocol consisted of the landmark phase at the end of the study after test swallows. Study duration, technical characteristics, indications, and motor findings were compared between standard and modified protocols. Of the 366 patients, 89.6% underwent the standard protocol (study duration 12.9 ± 0.3 min). In 10.4% with poor catheter tolerance undergoing the modified protocol, study duration was significantly longer (15.6 ± 1.0 min, p = 0.004) despite similar duration of study maneuvers. Only elevated upper esophageal sphincter basal pressures at the beginning of the study segregated modified protocol patients. The 95th percentile time to landmark phase in the standard protocol patients was 6.1 min; as many as 31.4% of modified protocol patients could not obtain their first study maneuver within this period (p = 0.0003). Interpretation was not impacted by shifting the landmark phase to the end of the study. Modification of the HRM study protocol with the landmark phase obtained at the end of the study optimizes study duration without compromising quality. © 2014 John Wiley & Sons Ltd.

    To maximize positive health outcomes for youth with HIV as they transition from youth to adult care, clinical staff need strategies and protocols to help youth maintain clinic engagement and medication adherence. Accordingly, this paper describe transition processes across twelve clinics within the Adolescent Medicine Trials Network for HIV/AIDS Interventions (ATN) to provide lessons learned and inform the development of transition protocols to improve health outcomes as youth shift from adolescent to adult HIV care. During a large multi-method Care Initiative program evaluation, three annual visits were completed at each site from 2010-2012 and conducted 174 semi-structured interviews with clinical and program staff (baseline n=64, year 1 n=56, year 2=54). The results underscore the value of adhering to recent American Academy of Pediatrics (AAP) transition recommendations, including: developing formal transition protocols, preparing youth for transition, facilitating youth's connection to the adult clinic, and identifying necessary strategies for transition evaluation. Transitioning youth with HIV involves targeting individual-, provider-, and system-level factors. Acknowledging and addressing key barriers is essential for developing streamlined, comprehensive, and context-specific transition protocols. Adolescent and adult clinic involvement in transition is essential to reduce service fragmentation, provide coordinated and continuous care, and support individual and community level health.

    Full Text Available To generate reference values for two inspiratory muscle endurance (IME protocols in healthy children and adolescents.This is an observational, cross-sectional study, in healthy children and adolescents from 4 to 18 years of age. Weight, height, maximal inspiratory pressure (MIP and IME were measured using two protocols. A fixed load of 30% of MIP with a 10% increment every 2 minutes was used in the incremental threshold loading protocol. As for the maximal loading protocol, a fixed load of 70% of MIP was used and the time limit (Tlim achieved until fatigue was measured.A total of 462 participants were included, 281 corresponding to the incremental loading protocol and 181 to maximal loading. There were moderate and positive correlations between IME and age, MIP, weight and height in the incremental threshold loading. However, the regression model demonstrated that MIP and age were the best variables to predict the IME. Otherwise, weak and positive correlations with age, weight and height were found in the maximal loading. Only age and height influenced endurance in the regression model. The predictive power (r2 of the incremental threshold loading protocol was 0.65, while the maximal loading was 0.15. The reproducibility measured by the intraclass correlation coefficient (ICC was higher in the incremental loading (0.96 compared to the maximal loading test (0.69.IME in healthy children and adolescents can be explained by age, height and MIP. The incremental threshold loading protocol showed more reliable results and should be the model of choice to evaluate IME in the pediatric age group.

    The reduction of prevalence rates of Internet Use Disorder (IUD) and its effective treatment are at high priority in both public health and educational policies. School-based preventive interventions facilitate a low-threshold approach for individuals with IUD, who are typically characterized by high therapy avoidance. Moreover, indicated approaches which target adolescents at high-risk show larger effects than universal prevention programs. Simultaneously, they reduce unnecessary burden for the majority of high-school students that is not at-risk. The PROTECT group intervention for indicated prevention of IUD in school settings was developed based on these preventive strategies. Three-hundred and forty adolescents, aged 12-18 years, from 40 secondary schools in Germany, screened for high-risk of IUD onset, are randomly assigned to a) PROTECT preventive intervention group or b) assessment only control group. The tested intervention consists of a cognitive-behavioral 4-session brief-protocol. Follow-up assessments are at 1, 4 and 12 months after admission. Primary outcome is the 12-months incidence rate of IUD. Secondary outcomes are the reduction of IUD and comorbid symptoms as well as the promotion of problem solving, cognitive restructuring and emotion regulation skills. The indicated preventive intervention PROTECT follows the APA-guidelines for psychological prevention, i.e., it is theory- and evidence-based and addresses both risk-reduction and strength-promotion, it considers current research and epidemiology and ethical standards such as professional secrecy and is designed as a systemic intervention at the school-level. It is expected that the intervention decreases risk of IUD onset (incidence rate). ClinicalTrials.gov: NCT02907658.

    Given the effect of musical training on the rate and accuracy of processing auditory information, therapeutic uses of music may potentially have remedial benefits for individuals with neurodevelopmental deficits. However, additional studies are needed to establish efficacy of music therapy interventions for attention skills in children/adolescents with neurodevelopmental disabilities including those with Autism Spectrum Disorders (ASD). To establish feasibility and preliminary efficacy of a group music therapy protocol to improve attention skills (sustained, selective, attentional control/switching) in adolescents diagnosed with autism and/or developmental delays. This single group pretest/posttest study took place in a private school for high functioning adolescents with neurodevelopmental delays. Nine students (4 males, 5 females), ages 13 to 20, participated in the study. Autism severity was assessed using the CARS2-HF and indicated the following distribution for study participants: severe (n = 3), mild (n = 4), or minimal/no (n = 2) symptoms. We assessed feasibility of implementing a 45-min Musical Attention Control Training (MACT) intervention delivered by a board-certified music therapist eight times over 6 weeks in a school setting. We also examined preliminary efficacy of the MACT to improve attention skills using the Test of Everyday Attention for Children (TEA-Ch). Parental consent rate was 100%. All nine participants successfully completed testing measures and 6 weeks of the intervention. Average participation rate was 97%. Data analysis showed positive trends and improvements on measures of attentional control/switching and selective attention. The results showed that the intervention and testing measures were feasible to implement and acceptable to the participants who all completed the protocol.

    Full Text Available The primary objective of this review was to update and discuss the current concepts andthe results of the treatment of acute lymphoblastic leukemia (ALL in adolescents and young adults(AYA. After a brief consideration of the epidemiologic and clinicobiologic characteristics of ALLin the AYA population, the main retrospective comparative studies stating the superiority ofpediatric over adult-based protocols were reviewed. The most important prospective studies inyoung adults using pediatric inspired or pediatric unmodified protocols were also reviewedemphasizing their feasibility at least up to the age of 40 yr and their promising results, with eventfreesurvival rates of 60-65% or greater. Results of trials from pediatric groups have shown that theunfavourable prognosis of adolescents is no more adequate. The majority of the older adolescentswith ALL can be cured with risk-adjusted and minimal residual disease-guided intensivechemotherapy, without stem cell transplantation. However, some specific subgroups, which aremore frequent in adolescents than in children (e.g., early pre-T, iAMP21, and BCR-ABL-like,deserve particular attention. In summary, the advances in treatment of ALL in adolescents havebeen translated to young adults, and that explains the significant improvement in survival of thesepatients in recent years.

    Study Objectives: The ability to recall facts is improved when learning takes place at spaced intervals, or when sleep follows shortly after learning. However, many students cram for exams and trade sleep for other activities. The aim of this study was to examine the interaction of study spacing and time in bed (TIB) for sleep on vocabulary learning in adolescents. Methods: In the Need for Sleep Study, which used a parallel-group design, 56 adolescents aged 15–19 years were randomly assigned to a week of either 5 h or 9 h of TIB for sleep each night as part of a 14-day protocol conducted at a boarding school. During the sleep manipulation period, participants studied 40 Graduate Record Examination (GRE)-type English words using digital flashcards. Word pairs were presented over 4 consecutive days (spaced items), or all at once during single study sessions (massed items), with total study time kept constant across conditions. Recall performance was examined 0 h, 24 h, and 120 h after all items were studied. Results: For all retention intervals examined, recall of massed items was impaired by a greater amount in adolescents exposed to sleep restriction. In contrast, cued recall performance on spaced items was similar between sleep groups. Conclusions: Spaced learning conferred strong protection against the effects of sleep restriction on recall performance, whereas students who had insufficient sleep were more likely to forget items studied over short time intervals. These findings in adolescents demonstrate the importance of combining good study habits and good sleep habits to optimize learning outcomes.

    Full Text Available Abstract Background Adolescents with cerebral palsy (CP show a reduced physical activity (PA. Currently there are no interventions for adolescents with CP in this critical life phase that optimise and maintain the individuals' physical activity in the long term. To develop such a program it is important to fully understand the factors that influence physical activity behaviours in adolescents with CP. The aim of this study is to explore what makes it easy or hard for adolescents with CP to be and to become physically active. Methods/Design A qualitative research method is chosen to allow adolescents to voice their own opinion. Because we will investigate the lived experiences this study has a phenomenological approach. Thirty ambulatory and non-ambulatory adolescents (aged 10-18 years with CP, classified as level I to IV on the Gross Motor Function Classification System and 30 parents of adolescents with CP will be invited to participate in one of the 6 focus groups or an individual interview. Therapists from all Children's Treatment Centres in Ontario, Canada, will be asked to fill in a survey. Focus groups will be audio- and videotaped and will approximately take 1.5 hours. The focus groups will be conducted by a facilitator and an assistant. In preparation of the focus groups, participants will fill in a demographic form with additional questions on physical activity. The information gathered from these questions and recent research on barriers and facilitators to physical activity will be used as a starting point for the content of the focus groups. Recordings of the focus groups will be transcribed and a content analysis approach will be used to code the transcripts. A preliminary summary of the coded data will be shared with the participants before themes will be refined. Discussion This study will help us gain insight and understanding of the participants' experiences and perspectives in PA, which can be of great importance when planning

    Hodgkin lymphoma (HL) treatment protocols for children, adolescents and young adults traditionally differ, but the biological and clinical justification for this remains uncertain. We compared age-dependent clinical presentation and treatment and outcome for 1072 classical HL patients 0-24 years diagnosed in Denmark (1990-2010) and Sweden (1992-2009) in pediatric (n = 315, Denmark clinical characteristics was assessed with Pearson's chi 2 -test and Mantel-Haenszel trend test. The Kaplan-Meier method was used for survival analyses. Hazard ratios (HR) were used to compare the different treatment groups and calculated using Cox regression. Children (0-9 years) less often presented with advanced disease than adolescents (10-17 years) and young adults (18-24 years) (stage IIB-IV: children 32% vs. adolescents 50%, and adults 55%; p clinical presentation suggesting a rationale of harmonized treatment for these groups. Both adult and pediatric protocols provided high OS with no significant difference between the departments. The less frequent use of radiotherapy in Danish pediatric patients corresponded to a lower EFS, but comparable OS in all groups confirmed effective rescue strategies for the relapsing patients.

    Introduction The prevalence of paediatric obesity is increasing, and with it, lifestyle-related diseases in children and adolescents. High-intensity interval training (HIIT) has recently been explored as an alternate to traditional moderate-intensity continuous training (MICT) in adults with chronic disease and has been shown to induce a rapid reversal of subclinical disease markers in obese children and adolescents. The primary aim of this study is to compare the effects of HIIT with MICT on myocardial function in obese children and adolescents. Methods and analysis Multicentre randomised controlled trial of 100 obese children and adolescents in the cities of Trondheim (Norway) and Brisbane (Australia). The trial will examine the efficacy of HIIT to improve cardiometabolic outcomes in obese children and adolescents. Participants will be randomised to (1) HIIT and nutrition advice, (2) MICT and nutrition advice or (3) nutrition advice. Participants will partake in supervised exercise training and/or nutrition sessions for 3 months. Measurements for study end points will occur at baseline, 3 months (postintervention) and 12 months (follow-up). The primary end point is myocardial function (peak systolic tissue velocity). Secondary end points include vascular function (flow-mediated dilation assessment), quantity of visceral and subcutaneous adipose tissue, myocardial structure and function, body composition, cardiorespiratory fitness, autonomic function, blood biochemistry, physical activity and nutrition. Lean, healthy children and adolescents will complete measurements for all study end points at one time point for comparative cross-sectional analyses. Ethics and dissemination This randomised controlled trial will generate substantial information regarding the effects of exercise intensity on paediatric obesity, specifically the cardiometabolic health of this at-risk population. It is expected that communication of results will allow for the development of

    Full Text Available Background and Objectives: Various extraction protocols have been followed for successful orthodontic treatment. The purpose of this study was to evaluate the extraction protocols in patients who had previously undergone orthodontic treatment and also who had reported for continuing orthodontic treatment from other clinics. Materials and Methods: One hundred thirty eight patients who registered for orthodontic treatment at the Faculty of Dentistry were divided into 10 extraction protocols based on the Orthodontic treatment protocol given by Janson et al. and were evaluated for statistical significance. Results: The descriptive statistics of the study revealed a total of 40 (29% patients in protocol 1, 43 (31.2% in protocol 2, 18 (13% in protocol 3, 16 (11.6% in protocol 5, and 12 (8.7% in Type 3 category of protocol 9. The Type 3 category in protocol 9 was statistically significant compared to other studies. Midline shift and collapse of the arch form were noticed in these individuals. Conclusion: Extraction of permanent teeth such as canine and lateral incisors without rational reasons could have devastating consequences on the entire occlusion. The percentage of cases wherein extraction of permanent teeth in the crowded region was adopted as a treatment option instead of orthodontic treatment is still prevalent in dental practice. The shortage of orthodontists in Malaysia, the long waiting period, and lack of subjective need for orthodontic treatment at an earlier age group were the reasons for the patient's to choose extraction of the mal-aligned teeth such as the maxillary canine or maxillary lateral incisors.

    There is now substantial evidence of a social gradient in bone health. Social stressors, related to socioeconomic status, are suggested to produce an inflammatory response marked by increased levels of proinflammatory cytokines. Here we focus on the particular role in the years before the achievement of peak bone mass, encompassing childhood, adolescence and young adulthood. An examination of such associations will help explain how social factors such as occupation, level of education and income may affect later-life bone disorders. This paper presents the protocol for a systematic review of existing literature regarding associations between socioeconomic factors and proinflammatory cytokines in those aged 6-30 years. We will conduct a systematic search of PubMed, OVID and CINAHL databases to identify articles that examine associations between socioeconomic factors and levels of proinflammatory cytokines, known to influence bone health, during childhood, adolescence or young adulthood. The findings of this review have implications for the equitable development of peak bone mass regardless of socioeconomic factors. Two independent reviewers will determine the eligibility of studies according to predetermined criteria, and studies will be assessed for methodological quality using a published scoring system. Should statistical heterogeneity be non-significant, we will conduct a meta-analysis; however, if heterogeneity prevent numerical syntheses, we will undertake a best-evidence analysis to determine whether socioeconomic differences exist in the levels of proinflammatory cytokines from childhood through to young adulthood. This study will be a systematic review of published data, and thus ethics approval is not required. In addition to peer-reviewed publication, these findings will be presented at professional conferences in national and international arenas. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    In 2013, the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) proposed nine internet gaming disorder (IGD) diagnostic criteria as a condition warranting further empirical and clinical research. The aim of this study is to clarify the natural and clinical courses of IGD proposed DSM-5 in adolescents and to evaluate its risk and protective factors. The Internet user Cohort for Unbiased Recognition of gaming disorder in Early Adolescence (iCURE) study is an ongoing multidisciplinary, prospective, longitudinal cohort study conducted in 21 schools in Korea. Participant recruitment commenced in March 2015 with the goal of registering 3000 adolescents. The baseline assessment included surveys on emotional, social and environmental characteristics. A parent or guardian completed questionnaires and a structured psychiatric comorbidity diagnostic interview regarding their children. Adolescents with the Internet Game Use-Elicited Symptom Screen total scores of 6 or higher were asked to participate in the clinical diagnostic interview. Two subcohorts of adolescents were constructed: a representative subcohort and a clinical evaluation subcohort. The representative subcohort comprises a randomly selected 10% of the iCURE to investigate the clinical course of IGD based on clinical diagnosis and to estimate the false negative rate. The clinical evaluation subcohort comprised participants meeting three or more of the nine IGD criteria, determined by clinical diagnostic interview, to show the clinical course of IGD. Follow-up data will be collected annually for the 3 years following the baseline assessments. The primary endpoint is 2-year incidence, remission and recurrence rates of IGD. Cross-sectional and longitudinal associations between exposures and outcomes as well as mediation factors will be evaluated. This study is approved by the Institutional Review Board of the Catholic University of Korea. Results will be published in peer

    Studies suggest that the quality of parent-adolescent communication about sex uniquely predicts adolescent sexual behavior. Previous studies have relied predominantly on self-report data. Observational methods, which are not susceptible to self-report biases, may be useful in examining the associations between the quality of parent-adolescent communication about sex and adolescent sexual behavior more objectively. With a sample of adolescents (N = 55, 58% male, 44% white, Mage = 15.8) and their parents, we used hierarchical logistic regression analyses to examine the associations between the observed quality of parent-adolescent communication about dating and sex and the likelihood of adolescents' sexual intercourse. The quality of parent-adolescent communication about dating and sex predicted sexual behavior. Specifically, lecturing was associated with a higher likelihood of adolescents having had sexual intercourse. The quality of parent-adolescent communication about sex is a unique correlate of adolescent sexual behavior and warrants further investigation. Thus, it serves as a potential target of preventive interventions that aim to foster adolescent sexual health behaviors. Copyright © 2015 Society for Adolescent Health and Medicine.

    Cognitive training has received increasing attention as a non-pharmacological approach for the treatment of attention deficit/hyperactivity disorder (ADHD) in children and adolescents. Few studies have assessed cognitive training as add-on treatment to medication in randomized placebo controlled trials. The purpose of this preliminary study was to explore the feasibility of implementing a computerized cognitive training program for ADHD in our environment, describe its main characteristics and potential efficacy in a small pilot study. Six ADHD patients aged 10-12-years old receiving stimulants and presenting residual symptoms were enrolled in a randomized clinical trial to either a standard cognitive training program or a controlled placebo condition for 12 weeks. The primary outcome was core ADHD symptoms measured using the Swanson, Nolan and Pelham Questionnaire (SNAP-IV scale). We faced higher resistance than expected to patient enrollment due to logistic issues to attend face-to-face sessions in the hospital and to fill the requirement of medication status and absence of some comorbidities. Both groups showed decrease in parent reported ADHD symptoms without statistical difference between them. In addition, improvements on neuropsychological tests were observed in both groups - mainly on trained tasks. This protocol revealed the need for new strategies to better assess the effectiveness of cognitive training such as the need to implement the intervention in a school environment to have an assessment with more external validity. Given the small sample size of this pilot study, definitive conclusions on the effects of cognitive training as add-on treatment to stimulants would be premature.

    Medical stabilization through inpatient nutritional rehabilitation is often necessary for patients with eating disorders (EDs) but includes the inherent risk of refeeding syndrome. Here we describe our experience of implementing and sustaining an inpatient nutritional rehabilitation protocol designed to strategically prepare patients with EDs and their families for discharge to a home setting in an efficient and effective manner from a general adolescent medicine unit. We report outcomes at admission, discharge, and 4-weeks follow-up. Protocol development, implementation, and unique features of the protocol, are described. Data were collected retrospectively as part of a continuous quality improvement (QI) initiative. Safety outcomes were the clinical need for phosphorus, potassium, and magnesium supplementation, other evidence of refeeding syndrome, and unexpected readmissions within one month of discharge. The value outcome was length of stay (LOS). Treatment outcomes were the percentage median BMI (MBMI) change from admission to discharge, and from discharge to 4-weeks follow-up visit. A total of 215 patients (88% F, 12% M) were included. Patients averaged 15.3 years old (5.8-23.2y); 64% had AN, 18% had atypical anorexia (AtAN), 6% bulimia nervosa (BN), 5% purging disorder (PD), 4% avoidant-restrictive food intake disorder (ARFID), and 3% had an unspecified food and eating disorder (UFED). Average LOS was 11 days. Initial mean calorie level for patients at admission was 1466 and at discharge 3800 kcals/day. Phosphorus supplementation for refeeding hypophosphatemia (RH) was needed in 14% of inpatients; full-threshold refeeding syndrome did not occur. Only 3.8% were rehospitalized in the thirty days after discharge. Patients averaged 86.1% of a median MBMI for age and gender, 91.4% MBMI at discharge, and 100.9% MBMI at 4-weeks follow-up. Mean percentage MBMI differences between time points were significantly different (admission-discharge: 5.3%, p  <0

    There is considerable ethical and legal ambiguity surrounding the role of adolescents in the decision-making process for research participation. Depending on the nature of the study and the regulations involved, adolescents may have independent responsibility for providing informed consent, they may be asked to provide their assent, or they may be completely excluded from the decision-making process. This study examined parent and adolescent perceptions of decision-making authority and sources of influence on adolescent research participation decisions, and examined whether perceptions of influence differed based on adolescent gender and level of research risk. Adolescents (n = 36) with asthma and their parents reviewed 9 pediatric research protocols, decided whether they would choose to participate, rated the extent they would be responsible for the actual decision, and indicated the ability of family and physician to influence their decisions. Multivariate analyses of variance were used to evaluate differences in perceptions of decision-making authority and sources of influence on the decisions. Adolescents were less willing to cede decision making authority to parents than parents anticipated. Parents and adolescents acknowledged a greater openness to influence from physicians than from family for above minimal risk studies. Parents were more willing to consider opinions from male adolescents. Adolescents desire responsibility for research participation decisions, though parents may not share these views. Physicians' views on research participation are important to families, especially for above minimal risk studies. Parents may grant more decision-making autonomy to adolescent males than to females. Researchers, physicians, and institutions play a key role in facilitating the ethical enrollment of adolescents into biomedical research.

    Family-based treatment is an efficacious treatment available for adolescents with anorexia nervosa. Yet the implementation of this treatment, at least in the United States, is challenging due to a limited number of trained family-based treatment therapists and the concentration of these therapists in a limited number of urban centers. The use of telemedicine in the delivery of family-based treatment can increase access to this therapy for this patient population. This two-year treatment development study (December 2013-November 2015) follows a two-wave iterative case series design. The study is ongoing and addresses the treatment needs of families in remote, rural, or underrepresented parts of the United States by delivering family-based treatment via telemedicine (video chat). The first six months of the study was dedicated to selecting a cloud-based secure telemedicine portal for use with participants. Recruitment for the first of two consecutive case series (N = 5) began during month seven. After these five patients completed treatment, a systematic review of treatment via feedback from participants and therapists related to the delivery of this model and use of technology was completed. A second wave of recruitment is underway (N = 5). At the end of both waves (N = 10), and after a second review of treatment, we should be able to establish the feasibility and acceptability of family-based treatment delivered via telemedicine for this patient population. This study is the first attempt to deliver family-based treatment for adolescents with anorexia nervosa via telemedicine. If delivering family-based treatment in this format is feasible, it will provide access to an evidence-based treatment for families heretofore unable to participate in specialist treatment for their child's eating disorder.

    User involvement has become a growing importance in healthcare. The United Nations state that adolescents have a right to be heard, and user involvement in healthcare is a legal right in many countries. Some research provides an insight into the field of user involvement in somatic and mental healthcare for adults, but little is known about user involvement in adolescents' mental healthcare, and no overview of the existing research evidence exists. The aim of this systematic review is to provide an overview of existing research reporting on experiences with and the effectiveness and safety issues associated with user involvement for adolescents' mental healthcare at the individual and organisational level. A systematic literature search and assessment of published research in the field of user involvement in adolescents' mental healthcare will be carried out. Established guidelines will be used for data extraction (Cochrane Collaboration guidelines, Strengthening the Reporting of Observational studies in Epidemiology and Critical Appraisal Skills Programme (CASP)), critical appraisal (Cochrane Collaboration guidelines and Pragmatic-Explanatory Continuum Indicator Summary) and reporting of results (Preferred Reporting Items for Systematic reviews and Meta-Analyses, Consolidated Standards of Reporting Trials and CASP). Confidence in the research evidence will be assessed using the Grading of Recommendations Assessment, Development and Evaluation approach. Adolescents are included as coresearchers for the planning and carrying out of this systematic review. This systematic review will provide an overview of the existing research literature and thereby fill a knowledge gap. It may provide various stakeholders, including decision-makers, professionals, individuals and their families, with an overview of existing knowledge in an underexplored field of research. Ethics approval is not required for this systematic review as we are not collecting primary data. The results

    The purpose of this article is to present findings from two parallel qualitative studies that used focus groups to explore adolescent views of psychological wellness and healthy bodies. Nine focus groups were held with 46 adolescents aged 16-19 years from two Mid-Western Canadian high schools. Both studies were designed with an interpretive humanist perspective and then a 6-step thematic approach was used to analyze the data. Common themes emerging in the focus group discussions in both studies included the negative impact of media on adolescent body image and pressure to conform to the Western views of physical appearance. These findings illustrate the need for nurses to understand the influence of the media on adolescents' views of their body image and to incorporate protocols for assessment, education, and counseling of adolescents on the healthy usage of media into their pediatric clinical practice. Through consistent participation in the development and implementation of health policies, nurses play a critical role in supporting adolescents to develop healthy views of body image.

    Rodent models provide valuable insight into mechanisms that underlie vulnerability to adverse effects of early-life challenges. Few studies have evaluated sex differences in anxiogenic or depressogenic effects of adolescent social stress in a rodent model. Furthermore, adolescent stress studies often use genetically heterogeneous outbred rodents which can lead to variable results. The current study evaluated the effects of adolescent social stress in male and female inbred (BALB/cJ) mice. Adolescent mice were exposed to repeat cycles of alternating social isolation and social novelty for 4 weeks. Adolescent social stress increased anxiety-related behaviors in both sexes and depression-related behavior in females. Locomotion/exploratory behavior was also decreased in both sexes by stress. Previously stressed adult mice produced less basal fecal corticosteroids than controls. Overall, the novel protocol induced sex-specific changes in anxiety- and depression-related behaviors and corticoid production in inbred mice. The chronic variable social stress protocol used here may be beneficial to systematically investigate sex-specific neurobiological mechanisms underlying adolescent stress vulnerability where genetic background can be controlled. © 2017 Wiley Periodicals, Inc.

    Physical activity levels are low amongst adolescent girls, and this population faces specific barriers to being active. Peer influences on health behaviours are important in adolescence, and peer-led interventions might hold promise to change behaviour. This paper describes the protocol for a feasibility cluster randomised controlled trial of Peer-Led physical Activity iNtervention for Adolescent girls (PLAN-A), a peer-led intervention aimed at increasing adolescent girls' physical activity levels. In addition, this paper describes an update that has been made to the protocol for the PLAN-A feasibility cluster randomised controlled trial. A two-arm cluster randomised feasibility trial will be conducted in six secondary schools (intervention n  = 4; control n  = 2) with year 8 (12-13 years old) girls. The intervention will operate at a year group level and consist of year 8 girls nominating influential peers within their year group to become peer supporters. Approximately 15% of the cohort will receive 3 days of training about physical activity and interpersonal communication skills. Peer supporters will then informally diffuse messages about physical activity amongst their friends for 10 weeks. Data will be collected at baseline (time 0 (T0)), immediately after the intervention (time 1 (T1)) and 12 months after baseline measures (time 2 (T2)). In this feasibility trial, the primary interest is in the recruitment of schools and participants (both year 8 girls and peer supporters), delivery and receipt of the intervention, data provision rates and identifying the cost categories for future economic analysis. Physical activity will be assessed using 7-day accelerometry, with the likely primary outcome in a fully powered trial being daily minutes of moderate-to-vigorous physical activity. Participants will also complete psychosocial questionnaires at each time point: assessing motivation, self-esteem and peer physical activity norms. Data analysis will be

    Data communication between nodes is carried out under Medium Access Control (MAC) protocol which is defined at data link layer. The MAC protocols are responsible to communicate and coordinate between nodes according to the defined standards in WSN (Wireless Sensor Networks). The design of a MAC protocol should also address the issues of energy efficiency and transmission efficiency. There are number of MAC protocols that exist in the literature proposed for WSN. In this paper, nine MAC protocols which includes S-MAC, T-MAC, Wise-MAC, Mu-MAC, Z-MAC, A-MAC, D-MAC, B-MAC and B-MAC+ for WSN have been explored, studied and analyzed. These nine protocols are classified in contention based and hybrid (combination of contention and schedule based) MAC protocols. The goal of this comparative study is to provide a basis for MAC protocols and to highlight different mechanisms used with respect to parameters for the evaluation of energy and transmission efficiency in WSN. This study also aims to give reader a better understanding of the concepts, processes and flow of information used in these MAC protocols for WSN. A comparison with respect to energy reservation scheme, idle listening avoidance, latency, fairness, data synchronization, and throughput maximization has been presented. It was analyzed that contention based MAC protocols are less energy efficient as compared to hybrid MAC protocols. From the analysis of contention based MAC protocols in term of energy consumption, it was being observed that protocols based on preamble sampling consume lesser energy than protocols based on static or dynamic sleep schedule.

    Psychiatric disorders are amongst the most prevalent and impairing conditions in childhood and adolescence. Unfortunately, it is well known that general practitioners (GPs) and other frontline health providers (i.e., child protection workers, public health nurses, and pediatricians) are not adequately trained to address these ubiquitous problems (Braddick et al. Child and Adolescent mental health in Europe: infrastructures, policy and programmes, European Communities, 2009; Levav et al. Eur Child Adolesc Psychiatry 13:395-401, 2004). Advances in technology may offer a solution to this problem with clinical decision support systems (CDSS) that are designed to help professionals make sound clinical decisions in real time. This paper offers a systematic review of currently available CDSS for child and adolescent mental health disorders prepared according to the PRISMA-Protocols (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols). Applying strict eligibility criteria, the identified studies (n = 5048) were screened. Ten studies, describing eight original clinical decision support systems for child and adolescent psychiatric disorders, fulfilled inclusion criteria. Based on this systematic review, there appears to be a need for a new, readily available CDSS for child neuropsychiatric disorder which promotes evidence-based, best practices, while enabling consideration of national variation in practices by leveraging data-reuse to generate predictions regarding treatment outcome, addressing a broader cluster of clinical disorders, and targeting frontline practice environments.

    Full Text Available Abstract Background Cognitive training has received increasing attention as a non-pharmacological approach for the treatment of attention deficit/hyperactivity disorder (ADHD in children and adolescents. Few studies have assessed cognitive training as add-on treatment to medication in randomized placebo controlled trials. The purpose of this preliminary study was to explore the feasibility of implementing a computerized cognitive training program for ADHD in our environment, describe its main characteristics and potential efficacy in a small pilot study. Methods Six ADHD patients aged 10-12-years old receiving stimulants and presenting residual symptoms were enrolled in a randomized clinical trial to either a standard cognitive training program or a controlled placebo condition for 12 weeks. The primary outcome was core ADHD symptoms measured using the Swanson, Nolan and Pelham Questionnaire (SNAP-IV scale. Results We faced higher resistance than expected to patient enrollment due to logistic issues to attend face-to-face sessions in the hospital and to fill the requirement of medication status and absence of some comorbidities. Both groups showed decrease in parent reported ADHD symptoms without statistical difference between them. In addition, improvements on neuropsychological tests were observed in both groups – mainly on trained tasks. Conclusions This protocol revealed the need for new strategies to better assess the effectiveness of cognitive training such as the need to implement the intervention in a school environment to have an assessment with more external validity. Given the small sample size of this pilot study, definitive conclusions on the effects of cognitive training as add-on treatment to stimulants would be premature.

    Overweight and obesity are significant public health concerns that are prevalent in younger age cohorts. Preventive or therapeutic interventions are difficult to implement and maintain over time. On the other hand, the majority of adolescents in the United States have a smartphone, representing a huge potential for innovative digitized interventions, such as weight loss programs delivered via smartphone applications. Although the number of available smartphone applications is increasing, evidence for their effectiveness in weight loss is insufficient. Therefore, the proposed study aims to assess the efficacy of a gamification-based smartphone application for weight loss in overweight and obese adolescents. The trial is designed to be a phase II, single-centre, two-arm, triple-blinded, randomized controlled trial (RCT) with a duration of 6 months. The intervention consists of a smartphone application that provides both tracking and gamification elements, while the control arm consists of an identically designed application solely with tracking features of health information. The proposed trial will be conducted in an urban primary care clinic of an academic centre in the United States of America, with expertise in the management of overweight and obese adolescents. Eligible adolescents will be followed for 6 months. Changes in body mass index z score from baseline to 6 months will be the primary outcome. Secondary objectives will explore the effects of the gamification-based application on adherence, as well as anthropometric, metabolic and behavioural changes. A required sample size of 108 participants (54 participants per group) was calculated. The benefits of the proposed study include mid-term effects in weight reduction for overweight and obese adolescents. The current proposal will contribute to fill a gap in the literature on the mid-term effects of gamification-based interventions to control weight in adolescents. This trial is a well-designed RCT that is in

    This longitudinal study examines the relationship between parenting behavior and adolescent adjustment (psychological well-being, substance abuse and delinquent behavior) in Chinese adolescents with economic disadvantage (N = 199). Results showed that parenting characteristics were concurrently and longitudinally related to measures of adolescent adjustment, particularly adolescent problem behavior. Compared with the norm based on adolescents of a community sample, poor adolescents perceived parenting characteristics to be more negative and they had relatively lower life satisfaction. Paternal parenting was perceived to be more negative than maternal parenting and parenting behavior was perceived to deteriorate over time.

    Full Text Available Context: Substance Use Disorders (SUDs are highly prevalent among inpatient adolescents with psychiatric disorders. In this population, substance use and other psychiatric outcomes can reinforce one another. Despite the need for integrated interventions in youths with dual diagnoses, few specific instruments are available. App-based technologies have shown promising results to help reduce substance use in adolescents, but their applicability in youths with associated severe psychiatric disorders is poorly documented. We aim to evaluate the feasibility of an ecological momentary assessment (EMA intervention for all substance users, and of a smart-phone application for cannabis users (Stop-Cannabis, for outpatient treatment after hospital discharge. Methods and analysis: All inpatient adolescents with psychiatric disorders hospitalized between 2016 and 2018 in a university hospital will be systematically screened for SUD and, if positive, will be assessed by an independent specialist addiction team. Participants with confirmed SUDs will be invited and helped to download an EMA app and, if required, the Stop-Cannabis app the week preceding hospital discharge. Information about the acceptability and use of both apps and the validity of EMA data in comparison to clinical assessments will be assessed after 6 months and one year.Discussion: This research has been designed to raise specific issues for consideration regarding the sequence between substance use, contextual factors, and other psychiatric symptoms among adolescents with comorbid severe psychiatric disorders. A better understanding of the mechanisms involved will inform the development of integrated treatment for dual disorders at that age.Ethics and dissemination: The study has already been approved and granted. Dissemination will include presentations at international congresses as well as publications in peer-reviewed journals.Trial registration: European Clinical Trials Database: Number

    Full Text Available Abstract Background Adolescent idiopathic scoliosis (AIS remains the most common deforming orthopedic condition in children. Increasingly, both adults and children are seeking complementary and alternative therapy, including chiropractic treatment, for a wide variety of health concerns. The scientific evidence supporting the use chiropractic intervention is inadequate. The purpose of this study was to conduct a pilot study and explore issues of safety, patient recruitment and compliance, treatment standardization, sham treatment refinement, inter-professional cooperation, quality assurance, and outcome measure selection. Methods Six patients participated in this 6-month study, 5 of whom were female. One female was braced. The mean age of these patients was 14 years, and the mean Cobb angle was 22.2 degrees. The study design was a randomized controlled clinical trial with two independent and blinded observers. Three patients were treated by standard medical care (observation or brace treatment, two were treated with standard medical care plus chiropractic manipulation, and one was treated with standard medical care plus sham manipulation. The primary outcome measure was Cobb, and the psychosocial measure was Scoliosis Quality of Life Index. Results Orthopedic surgeons and chiropractors were easily recruited and worked cooperatively throughout the trial. Patient recruitment and compliance was good. Chiropractic treatments were safely employed, and research protocols were successful. Conclusion Overall, our pilot study showed the viability for a larger randomized trial. This pilot confirms the strength of existing protocols with amendments for use in a full randomized controlled trial.

    Clemes, Stacy A; Biddle, Stuart J H

    2013-02-01

    Pedometers are increasingly being used to measure physical activity in children and adolescents. This review provides an overview of common measurement issues relating to their use. Studies addressing the following measurement issues in children/adolescents (aged 3-18 years) were included: pedometer validity and reliability, monitoring period, wear time, reactivity, and data treatment and reporting. Pedometer surveillance studies in children/adolescents (aged: 4-18 years) were also included to enable common measurement protocols to be highlighted. In children > 5 years, pedometers provide a valid and reliable, objective measure of ambulatory activity. Further evidence is required on pedometer validity in preschool children. Across all ages, optimal monitoring frames to detect habitual activity have yet to be determined; most surveillance studies use 7 days. It is recommended that standardized wear time criteria are established for different age groups, and that wear times are reported. As activity varies between weekdays and weekend days, researchers interested in habitual activity should include both types of day in surveillance studies. There is conflicting evidence on the presence of reactivity to pedometers. Pedometers are a suitable tool to objectively assess ambulatory activity in children (> 5 years) and adolescents. This review provides recommendations to enhance the standardization of measurement protocols.

    Sexual violence is a public health problem in Puerto Rico (PR), with an incidence of 7.4 cases for every 10,000 people during 2005-2006 (Departamento de Salud Secretaría Auxiliar de Salud Familiar y Servicios Integrados, 2007). Findings from the literature review indicated that the traditional model of care provided to the victims of sexual violence in the Emergency Department is incomplete; furthermore, it may cause revictimization because of the attitudes, behaviors, and practices of the community service providers, resulting in additional trauma. Emerging evidence demonstrates that Sexual Assault Nurse Examiner (SANE) programs are providing effective quality care. In PR, SANEs do not intervene in sexual assault cases; nevertheless, the Department of Health of PR has recognized the importance of SANE intervention. Consequently, there is a need for current evidence-based protocols and standards of care to describe the procedures, roles, and responsibilities for the provision of quality care to victims. This project involves the implementation of the Stufflebeam's Context-Input-Process-Product Model in the creation of the Commonwealth of Puerto Rico National Protocol for the Management of Victims of Sexual Violence: Adults/Adolescents.

    Handball is a physical contact sport that includes frequent overhead throwing, and this combination leads to a high rate of shoulder injuries. Several factors have been associated with shoulder injuries in overhead athletes, but strong scientific evidence is lacking for most suggested risk factors. We therefore designed the Karolinska Handball Study (KHAST) with the aim to identify risk factors for shoulder injuries in adolescent male and female elite handball players studying at handball-profiled secondary schools in Sweden. Secondary objectives are to investigate whether shoulder function changes during the competition season and whether the physical profile of the players changes during their time in secondary school. Players aged 15 to 19 years were included during the pre-season period of the 2014-2015 and the 2015-2016 seasons. At inclusion, players signed informed consent and filled in a questionnaire regarding playing position, playing level, previous handball experience, history of shoulder problems and athletic identity. Players also completed a detailed test battery at baseline evaluating the shoulder, neck and trunk. Players were then prospectively monitored weekly during the 2014-2015 and/or 2015-2016 competitive seasons regarding injuries and training/match workload. Results from the annual routine physical tests in the secondary school curriculum including bench press, deep squat, hand grip strength, clean lifts, squat jumps, counter movement jumps, handball players and a reduction of these injuries is therefore warranted. However, in order to introduce appropriate preventive measures, a detailed understanding of the underlying risk factors is needed. Our study has a high potential to identify important risk factors for shoulder injuries in adolescent elite handball players owing to a large study sample, a high response rate, data collection during consecutive seasons, and recording of potential confounding factors.

    This study examined how motor limitations in terms of reduced possibilities to move influence aggression, starting from the fact that motor skills and movement have an important place in the expression of aggression, as well as the tendency of adolescents to "body language". Adolescent with motor deficit is hindered in gaining experience of one's own body, which is reflected in the formation of complete experience of himself, or constitution of the self. In many of the functions of motor skills and movement aggression has a significant place that we wanted to determine without deeper analysis of whether the origin of aggression is instinctive or it is always just the result of frustration. The sample on which testing was performed consisted of 100 randomly selected subjects of both genders aged 16-18 years. Fifty subjects had motor limitations due to illness or injury, and another fifty subjects had intact motor functions. The study used three instruments: 1) A-87 questionnaire for aggressiveness examination; 2) structured interview; and 3) protocol for observation under natural conditions. Results of the analysis of data obtained in total score, as well as in all five subscales of the A-87 questionnaire for aggressiveness examination showed that the two groups were not significantly different. The results obtained by structured interview showed the adolescents with motor limitations to demonstrate greater verbal aggressiveness, then latent physical aggressiveness. A statistically significant between-group difference was obtained on the factor of self-destructiveness, which implies that adolescents with motor limitations are somewhat more self-destructive compared to those in control group. From the results obtained by the protocol for systematic observation in natural conditions, it was evident that there were significant differences on most of perceptual conducts between control and experimental group, whereby adolescents with motor limitations were more

    Spiritual struggles are associated with poorer health outcomes, including depression, which has higher prevalence among transgender individuals than the general population. This study's objective was to improve the quality of care in an outpatient transgender clinic by screening patients and caregivers for spiritual struggle and future intervention. The quality improvement questions addressed were whether screening for spiritual struggle was feasible and acceptable; and whether the sensitivity and specificity of the Rush Protocol were acceptable. Revision of the screening was based on cognitive interviews with the 115 adolescents and caregivers who were screened. Prevalence of spiritual struggle was 38-47%. Compared to the Negative R-COPE, the Rush Protocol screener had sensitivities of 44-80% and specificities of 60-74%. The Rush Protocol was acceptable to adolescents seen in a transgender clinic, caregivers, and clinic staff; was feasible to deliver during outpatient clinic visits, and offers a straightforward means of identifying transgender persons and caregivers experiencing spiritual struggle.

    Analysis of the association between exposure to electromagnetic fields of non-ionising radiation (EMF-NIR) and health in children and adolescents is hindered by the limited availability of data, mainly due to the difficulties on the exposure assessment. This study protocol describes the methodologies used for characterising exposure of children to EMF-NIR in the INMA (INfancia y Medio Ambiente- Environment and Childhood) Project, a prospective cohort study. Indirect (proximity to emission sources, questionnaires on sources use and geospatial propagation models) and direct methods (spot and fixed longer-term measurements and personal measurements) were conducted in order to assess exposure levels of study participants aged between 7 and 18 years old. The methodology used varies depending on the frequency of the EMF-NIR and the environment (homes, schools and parks). Questionnaires assessed the use of sources contributing both to Extremely Low Frequency (ELF) and Radiofrequency (RF) exposure levels. Geospatial propagation models (NISMap) are implemented and validated for environmental outdoor sources of RFs using spot measurements.

    Full Text Available Abstract Background Analysis of the association between exposure to electromagnetic fields of non-ionising radiation (EMF-NIR and health in children and adolescents is hindered by the limited availability of data, mainly due to the difficulties on the exposure assessment. This study protocol describes the methodologies used for characterising exposure of children to EMF-NIR in the INMA (INfancia y Medio Ambiente- Environment and Childhood Project, a prospective cohort study. Methods/Design Indirect (proximity to emission sources, questionnaires on sources use and geospatial propagation models and direct methods (spot and fixed longer-term measurements and personal measurements were conducted in order to assess exposure levels of study participants aged between 7 and 18 years old. The methodology used varies depending on the frequency of the EMF-NIR and the environment (homes, schools and parks. Questionnaires assessed the use of sources contributing both to Extremely Low Frequency (ELF and Radiofrequency (RF exposure levels. Geospatial propagation models (NISMap are implemented and validated for environmental outdoor sources of RFs using spot measurements.

    Research investigating the effectiveness of universal interventions to reduce the risk of mental health problems remains limited. Schools are a promising setting within which adolescents can receive interventions aimed at promoting their mental health. The aim of this study is to assess the effectiveness of a resilience-based prevention-focused intervention in reducing the risk of mental health problems among adolescents attending secondary school in socio-economically disadvantaged areas. A cluster randomised control trial will be conducted, with schools as the unit of randomisation. Initially, 32 secondary schools will be randomly allocated to a control or intervention group (12 control and 20 intervention). An intervention focused on improving student internal and external resilience factors will be implemented in intervention schools. A survey of students in Grade 7 in both intervention and control schools will be conducted (baseline) and repeated three years later when the students are in Grade 10. The Strengths and Difficulties Questionnaire will be used to measure the risk of mental health problems. At follow-up, the risk of mental health problems will be compared between Grade 10 students in intervention and control schools to determine intervention effectiveness. The study presents an opportunity to determine the effectiveness of a comprehensive resilience-based intervention in reducing the risk of mental health problems in adolescents attending secondary schools. The outcomes of the trial are of importance to youth, schools, mental health clinicians and policymakers.

    The aim of this study was to characterize the diet of Uruguayan adolescents and demographic aspects that influence it. The data come from the National Survey of Adolescents and Youth in 2008 which worked with 2,943 cases, representative sample of all adolescents in Uruguay. The characteristics of feeding studied were: consumption of fruits and vegetables, soft drinks, fast food, added salt to meals served at the table and meal times shared with a parent. These variables were also studied in aggregate to determine a pattern of eating behavior. It was found that 89% of adolescents did not meet the recommendation of 5 servings of fruits and vegetables a day, 50% consumed daily soft drinks, fast foods ingested 24% 2 or more times per week and 13% added salt at all preparations. We also found that 31% did not share mealtimes with parents daily. By adding the variables studied, we observed that 58% were inadequately fed, and is higher among older adolescents (p economic situation and residents within the country..

    Adolescent pregnancies pose a risk to the young mothers and their babies. In Zambia, 35% of young girls in rural areas have given birth by the age of 18 years. Pregnancy rates are particularly high among out-of-school girls. Poverty, low enrolment in secondary school, myths and community norms all contribute to early childbearing. This protocol describes a trial aiming to measure the effect on early childbearing rates in a rural Zambian context of (1) economic support to girls and their families, and (2) combining economic support with a community intervention to enhance knowledge about sexual and reproductive health and supportive community norms. This cluster randomized controlled trial (CRCT) will have three arms. The clusters are rural schools with surrounding communities. Approximately 4900 girls in grade 7 in 2016 will be recruited from 157 schools in 12 districts. In one intervention arm, participating girls and their guardians will be offered cash transfers and payment of school fees. In the second intervention arm, there will be both economic support and a community intervention. The interventions will be implemented for approximately 2 years. The final survey will be 4.5 years after recruitment. The primary outcomes will be "incidence of births within 8 months of the end of the intervention period", "incidence of births before girls' 18th birthday" and "proportion of girls who sit for the grade 9 exam". Final survey interviewers will be unaware of the intervention status of respondents. Analysis will be by intention-to-treat and adjusted for cluster design and confounders. Qualitative process evaluation will be conducted. This is the first CRCT to measure the effect of combining economic support with a community intervention to prevent adolescent childbearing in a low- or middle-income country. We have designed a programme that will be sustainable and feasible to scale up. The findings will be relevant for programmes for adolescent reproductive health in

    Earthquakes, which can cause widespread territorial and socio-economic destruction, are life-threatening, unexpected, unpredictable, and uncontrollable events caused by the shaking of the surface of the earth. The psychological consequences, such as PTSD, anxiety, depression, and suicidal ideation, are well-known to clinicians and researchers. This study was conducted with the aim of evaluating the use of the Eye Movement Desensitization and Reprocessing (EMDR) Integrative Group Treatment Protocol on a sample of adolescents, after the earthquake in Central Italy on 24 August 2016. The objective of the EMDR intervention was to reduce PTSD symptoms. Before and after EMDR, specific assessment to find changes in PTSD symptoms was made using the Impact of Event Scale-Revised and through the analyses of the Subjective Units of Disturbance. The EMDR treatment was given in three sessions (T1, T2, and T3), each lasting 90 min, and the results at follow-up phase (T4) were also monitored. The results are very encouraging, showing significantly reduced PTSD symptoms in the majority of the subjects. The clinical implications and limitations will be discussed.

    The negative consequences of unhealthy weight gain and the high likelihood of pediatric obesity tracking into adulthood highlight the importance of targeting youth who are 'at risk' of obesity. The aim of this paper is to report the rationale and study protocol for the 'Active Teen Leaders Avoiding Screen-time' (ATLAS) obesity prevention intervention for adolescent boys living in low-income communities. The ATLAS intervention will be evaluated using a cluster randomized controlled trial in 14 secondary schools in the state of New South Wales (NSW), Australia (2012 to 2014). ATLAS is an 8-month multi-component, school-based program informed by self-determination theory and social cognitive theory. The intervention consists of teacher professional development, enhanced school-sport sessions, researcher-led seminars, lunch-time physical activity mentoring sessions, pedometers for self-monitoring, provision of equipment to schools, parental newsletters, and a smartphone application and website. Assessments were conducted at baseline and will be completed again at 9- and 18-months from baseline. Primary outcomes are body mass index (BMI) and waist circumference. Secondary outcomes include BMI z-scores, body fat (bioelectrical impedance analysis), physical activity (accelerometers), muscular fitness (grip strength and push-ups), screen-time, sugar-sweetened beverage consumption, resistance training skill competency, daytime sleepiness, subjective well-being, physical self-perception, pathological video gaming, and aggression. Hypothesized mediators of behavior change will also be explored. ATLAS is an innovative school-based intervention designed to improve the health behaviors and related outcomes of adolescent males in low-income communities. Copyright © 2013 Elsevier Inc.

    Few studies have reported long-term follow-up data in adults and even fewer in adolescents. The purpose of this work is to report on the longest follow-up assessment in the literature on treatments for adolescents with social phobia. A 5-year follow-up assessment was conducted with subjects who originally received either Cognitive Behavioral Group Therapy for Adolescents (CBGT-A), Social Effectiveness Therapy for Adolescents--Spanish version (SET-Asv), or Intervención en Adolescentes con Fobia Social--Treatment for Adolescents with Social Phobia (IAFS) in a controlled clinical trial. Twenty-three subjects completing the treatment conditions were available for the 5-year follow-up. Results demonstrate that subjects treated either with CBGT-A, SET-Asv and IAFS continued to maintain their gains after treatments were terminated. Either the CBGT-A, SET-Asv and IAFS can provide lasting effects to the majority of adolescents with social anxiety. Issues that may contribute to future research and clinical implications are discussed.

    Full Text Available Abstract Background Alcohol misuse amongst young people is a serious concern. The need for effective prevention is clear, yet there appear to be few evidenced-based programs that prevent alcohol misuse and none that target both high and low-risk youth. The CAP study addresses this gap by evaluating the efficacy of an integrated approach to alcohol misuse prevention, which combines the effective universal internet-based Climate Schools program with the effective selective personality-targeted Preventure program. This article describes the development and protocol of the CAP study which aims to prevent alcohol misuse and related harms in Australian adolescents. Methods/Design A cluster randomized controlled trial (RCT is being conducted with Year 8 students aged 13 to 14-years-old from 27 secondary schools in New South Wales and Victoria, Australia. Blocked randomisation was used to assign schools to one of four groups; Climate Schools only, Preventure only, CAP (Climate Schools and Preventure, or Control (alcohol, drug and health education as usual. The primary outcomes of the trial will be the uptake and harmful use of alcohol and alcohol related harms. Secondary outcomes will include alcohol and cannabis related knowledge, cannabis related harms, intentions to use, and mental health symptomatology. All participants will complete assessments on five occasions; baseline; immediately post intervention, and at 12, 24 and 36 months post baseline. Discussion This study protocol presents the design and current implementation of a cluster RCT to evaluate the efficacy of the CAP study; an integrated universal and selective approach to prevent alcohol use and related harms among adolescents. Compared to students who receive the stand-alone universal Climate Schools program or alcohol and drug education as usual (Controls, we expect the students who receive the CAP intervention to have significantly less uptake of alcohol use, a reduction in average

    Full Text Available The transition from pediatric to adult medical services has a greater impact on the care of adolescents or young adults with chronic diseases such as cystinosis. This transition period is a time of psychosocial development and new responsibilities placing these patients at increased risk of non-adherence. This can lead to serious adverse effects such as graft loss and progression of the disease. Our transition protocol will provide patients, families, physicians, and all those involved a structured guide to transitioning cystinosis patients. This structured protocol depends on four areas of competency: Recognition, Insight, Self-reliance, and Establishment of healthy habits (RISE. This protocol has not been tested and therefore challenges not realized. With a focus on medical, social, and educational/vocational aspects, we aim to improve transition for cystinosis patients in all aspects of their lives.

    Mid to late adolescence is characterised by a vulnerability to problematic substance use since the consumption of alcohol and illicit drugs is frequently initiated and increased in this life period. While the detrimental long- and short-term effects of problematic consumption patterns in adolescence pose a major public health concern, current prevention programs targeting alcohol- and other substance-using adolescents are scarce. The study described in this protocol will test the effectiveness of a web-based brief intervention aimed at reducing problematic alcohol use and promoting abstinence from illegal drugs in adolescents with risky substance use aged 16 to 18 years old in four EU-countries. To determine the effectiveness of our web-BI, we apply a two-arm randomized controlled trial (RCT) study design, with baseline assessment at study entry and a three month follow-up assessment. Adolescents aged 16 to 18 years from Belgium, the Czech Republic, Germany, and Sweden will be randomly assigned to either the fully electronically delivered brief intervention group (N = 400) or an assessment only control group (N = 400) depending on their screening for risky substance use (using the CRAFFT). Recruitment, informed consent, randomization, intervention and follow-up will be implemented online. Primary outcomes are reductions in frequency and quantity of use of alcohol and drugs other than alcohol over a 30 day period, as well as consumption per typical occasion. Secondary outcomes concern changes in substance use related cognitions including the constructs of the Theory of Planned Behaviour, implementation intentions, and stages of change. Moreover the study addresses a number of moderator variables, including age of first use, general psychopathology and quality of parent-child relationship. The trial is expected to contribute to the growing literature on theory- and web-based brief interventions for adolescents. We will explore the potential of using web

    This article is a case study of a Puerto Rican adolescent with suicidal behavior. The adolescent began a Socio-Cognitive Behavioral Therapy for Suicidal Behavior (SCBT), an ambulatory treatment, after being hospitalized for a suicide attempt. The SCBT incorporates an ecological and developmental perspective to CBT. She initially presented low self-esteem, and significant depressive and anxiety symptoms. At the end of treatment, the adolescent revealed a significant change in symptoms, and a better use of her coping skills. No suicidal ideation was presented during previous months, neither during follow up. Case analysis allowed treatment protocol modifications, particularly family sessions and communication skills, thus contributing to its further feasibility.

    Full Text Available The authors define adolescence and developmental dysplasia of the hip (DDH. Special attention is paid to pathological findings characteristic of DDH in adolescence (unrecognized and untreated DDH; treated DDH, but non-terminated treatment; DDH diagnosed with delay, inadequately treated, with complications. The authors emphasise that DDH treatment has to be successfully terminated well before the adolescence; possibilities are explained on management modes at the time of adolescence, and possible persons guilty for the persistence of later hip problems are indicated. Based on the authors' experience and having in mind all surgical possibilities for the treatment (pelvic osteotomies, femoral osteotomies, trochanteroplasties, leg length equalization procedures the authors propose treatment protocols. The intention is to provide better treatment results and to prevent secondary hip arthrosis. Furthermore, how to improve the struggle against DDH is suggested.

Methods Following a brief review of the acute outcomes of the CAMS trial, as well as the psychosocial and pharmacologic treatment literature for pediatric anxiety disorders, the design and methods of the CAMS trial are described. Results CAMS was a six-year, six-site, randomized controlled trial. Four hundred eighty-eight (N = 488 children and adolescents (ages 7-17 years with DSM-IV-TR diagnoses of SAD, GAD, or SoP were randomly assigned to one of four treatment conditions: CBT, SRT, COMB, or PBO. Assessments of anxiety symptoms, safety, and functional outcomes, as well as putative mediators and moderators of treatment response were completed in a multi-measure, multi-informant fashion. Manual-based therapies, trained clinicians and independent evaluators were used to ensure treatment and assessment fidelity. A multi-layered administrative structure with representation from all sites facilitated cross-site coordination of the entire trial, study protocols and quality assurance. Conclusions CAMS offers a model for clinical trials methods applicable to psychosocial and psychopharmacological comparative treatment trials by using state-of-the-art methods and rigorous cross-site quality controls. CAMS also provided a large-scale examination of the relative and combined efficacy and safety of the best evidenced-based psychosocial (CBT and pharmacologic (SSRI treatments to date for the most commonly occurring pediatric anxiety disorders.

The aim of this study was to investigate the association of cardiometabolic risk factors with H. pylori infection in Iranian adolescents. Materials and Methods: The current study was conducted along with the third survey of a national school-based surveillance system in Iran, entitled "Childhood and Adolescence Surveillance and Prevention of Adult Non-communicable Disease" (CASPIAN study. Detailed questionnaires on demographic, socioeconomic, dietary, and health-related information of the participants were filled by one of the parents under supervision of trained health-care workers. Trained healthcare professionals measured anthropometric indices, blood pressures according to standard protocols. Fasting venous blood was examined for fasting blood sugar and lipid profile. Results: Overall 882 serum samples were suitable for testing. H. pylori antibody was found in 643 serum samples (72.9%. Among cardiometabolic risk factors, only the mean weight of participants was different between two groups (44.6±11.8 in H. pylori positive and 42.8±11.3 in H. pylori negative group; p=0.04. Overall, 5.1% of adolescents with positive H. pylori tests were overweight or obese, while 1.7% of negative ones were so (p=0.02. In the multivariate regression model, H. pyloriseropositivity increased the risk of overweight (OR, 3.3; 95%CI, 1.2-9.3; p= 0.03. In the multivariate model, association of other cardiometabolic risk factors with H. pylori infection was not statistically significant (p>0.05. Conclusion: Results of present study showed that H. pylori infection was associated with excess weight in adolescents. H. pylori eradication may be decrease the risk of obesity.

    Providing e-learning modules can be an effective strategy for enhancing gatekeepers' knowledge, self-confidence and skills in adolescent suicide prevention. The aim of this study was to test the effectiveness of an online training program called Mental Health Online which consists of eight short e-learning modules, each capturing an important aspect of the process of recognition, guidance and referral of suicidal adolescents (12-20 years). The primary outcomes of this study are participant's ratings on perceived knowledge, perceived self-confidence, and actual knowledge regarding adolescent suicidality. A randomized controlled trial will be carried out among 154 gatekeepers. After completing the first assessment (pre-test), participants will be randomly assigned to either the experimental group or the waitlist control group. One week after completing the first assessment the experimental group will have access to the website Mental Health Online containing the eight e-learning modules and additional information on adolescent suicide prevention. Participants in both conditions will be assessed 4 weeks after completing the first assessment (post-test), and 12 weeks after completing the post-test (follow-up). At post-test, participants from the experimental group are asked to complete an evaluation questionnaire on the modules. The waitlist control group will have access to the modules and additional information on the website after completing the follow-up assessment. Gatekeepers can benefit from e-learning modules on adolescent suicide prevention. This approach allows them to learn about this sensitive subject at their own pace and from any given location, as long as they have access to the Internet. Given the flexible nature of the program, each participant can compose his/her own training creating an instant customized course with the required steps in adolescent suicide prevention.

    Scholars have identified dating violence as a public health issue among adolescents. Yet, minimal research has detailed adolescents' perceptions of dating violence, specifically gender differences in perceptions. Research suggests that in order for dating violence prevention and intervention to be effective, services need to be delivered in a manner that is understood by adolescents. Therefore, this study used a qualitative phenomenology study to investigate adolescents' perceptions of dating violence, including gender differences in adolescents' perceptions. Thirty adolescents between the ages of 14 and 19 from a Midwest public high school participated in focus groups. Focus group participants were asked semistructured interview questions regarding the definition of dating violence, risk and protective factors for dating violence, support for victims and perpetrators, and prevention efforts. Data were analyzed using qualitative content analysis methods, and common themes were identified. Adolescents' language revealed gender differences in perceptions toward dating violence. Males perceive dating violence through action, perpetration, and physical consequences. Females discuss dating violence by relating to the victim and the victim's emotions. Although gender differences existed in participants' perceptions, both males and females explained that dating violence is more often perpetrated by females, despite the view from society that males are more likely to perpetrate dating violence. Findings suggest that schools, practitioners, and policy makers are not meeting the needs of adolescents in regard to dating violence prevention and intervention. Prevention and intervention efforts could be improved by delivering education and services using language that adolescents find relevant. Findings also suggest that adolescents may benefit from prevention and intervention with gender specific components.

    The National Human Papillomavirus (HPV) Vaccination Program in Australia commenced in 2007 for females and in 2013 for males, using the quadrivalent HPV vaccine (HPV 6,11,16,18). Thus far, we have demonstrated very substantial reductions in genital warts and in the prevalence of HPV among young Australian women, providing early evidence for the success of this public health initiative. Australia has a long history of school-based vaccination programs for adolescents, with comparatively high coverage. However, it is not clear what factors promote success in a school vaccination program. The HPV.edu study aims to examine: 1) student knowledge about HPV vaccination; 2) psycho-social outcomes and 3) vaccination uptake. HPV.edu is a cluster randomised trial of a complex intervention in schools aiming to recruit 40 schools with year-8 enrolments above 100 students (approximately 4400 students). The schools will be stratified by Government, Catholic, and Independent sectors and geographical location, with up to 20 schools recruited in each of two states, Western Australia (WA) and South Australia (SA), and randomly allocated to intervention or control (usual practice). Intervention schools will receive the complex intervention which includes an adolescent intervention (education and distraction); a decisional support tool for parents and adolescents and logistical strategies (consent form returns strategies, in-school mop-up vaccination and vaccination-day guidelines).

    Supportive parent involvement for adolescents' type 1 diabetes (T1D) self-management promotes optimal diabetes outcomes. However, family conflict is common and can interfere with collaborative family teamwork. Few interventions have used explicitly strengths-based approaches to help reinforce desired management behaviors and promote positive family interactions around diabetes care. The aim of this protocol was to describe the development of a new, strengths-based behavioral intervention for parents of adolescents with T1D delivered via a mobile-friendly Web app called Type 1 Doing Well. Ten adolescent-parent dyads and 5 diabetes care providers participated in a series of qualitative interviews to inform the design of the app. The 3- to 4-month pilot intervention will involve 82 parents receiving daily prompts to use the app, in which they will mark the diabetes-related strength behaviors (ie, positive attitudes or behaviors related to living with or managing T1D) their teen engaged in that day. Parents will also receive training on how to observe diabetes strengths and how to offer teen-friendly praise via the app. Each week, the app will generate a summary of the teen's most frequent strengths from the previous week based on parent reports, and parents will be encouraged to praise their teen either in person or from a library of reinforcing text messages (short message service, SMS). The major outcomes of this pilot study will include intervention feasibility and satisfaction data. Clinical and behavioral outcomes will include glycemic control, regimen adherence, family relationships and conflict, diabetes burden, and health-related quality of life. This strengths-based, mobile health (mHealth) intervention aims to help parents increase their awareness of and efforts to support their adolescents' engagement in positive diabetes-related behaviors. If efficacious, this intervention has the potential to reduce the risk of family conflict, enhance collaborative

    Facebook continues to grow in popularity among adolescents as well as adolescent researchers. Guidance on conducting research using Facebook with appropriate attention to privacy and ethics is scarce. To inform such research efforts, the purpose of this study was to determine older adolescents' responses after learning that they were participants in a research study that involved identification of participants using Facebook. Public Facebook profiles of older adolescents aged 18-19 years from a large state university were examined. Profile owners were then interviewed. During the interview, participants were informed that they were identified by examining publicly available Facebook profiles. Participants were asked to discuss their views on this research method. A total of 132 participants completed the interview (70% response rate); the average age was 18.4 years (SD = .5); and our sample included 64 male participants (48.5%). Participant responses included endorsement (19.7%), fine (36.4%), neutral (28.8%), uneasy (9.1%), and concerned (6.1%). Among participants who were uneasy or concerned, the majority voiced confusion regarding their current profile security settings (p = .00). The majority of adolescent participants viewed the use of Facebook for research positively. These findings are consistent with the approach taken by many U.S. courts. Researchers may consider these findings when developing research protocols involving Facebook. Copyright © 2012 Society for Adolescent Health and Medicine. Published by Elsevier Inc.

    Physiological and behavioral aspects of masticatory function may have an impact on nutritional status, which has been little studied. The aim was to perform a comprehensive evaluation of objective, subjective and behavioral aspects of masticatory function in 231 adolescents, aged 14-17 years and compare these parameters between normal-weight (n = 115) and adolescents with overweight/obesity (n = 116). Objective aspects were examined by the Oro-facial Myofunctional Evaluation-expanded protocol (OMES-e), determining the masticatory type, chewing time/frequency, abnormal movements, and other; masticatory performance (color changeable chewing gum) and bite force were also explored. The subjective and behavioral evaluations were assessed using the Quality of Mastication Function Questionnaire, which explores the masticatory behavior and frequency/intensity of difficulty in chewing different types of foods. Results were submitted to normality tests, Chi-square, unpaired t-test and Mann-Whitney. A multiple linear regression model was used to evaluate which of the variables under study contributed to the variation in Percent Body Fat (α = 0.05). The results showed that OMES-e total score differed significantly between groups, that is, individuals with overweight showed more changes in oro-facial myofunctional aspects than normal-weight ones. Unilateral mastication was more frequent among females with overweight/obesity. They also showed greater difficulty on Habits and Fruit domains, reporting the need of adding sauce to the meal to facilitate swallowing and peeling and cutting fruit (apples) in small pieces in order to better chew them. OMES-e total score also showed a significant relationship with Percent Body Fat. Masticatory performance evaluated by chewing gum and bite force did not differ between groups. This study showed that adolescents with excess weight presented changes in masticatory behavior and greater difficulty in performing the masticatory function

    Full Text Available Adolescent depression is a prevalent disorder with substantial morbidity and mortality. Current treatment interventions do not target relevant pathophysiology and are frequently ineffective, thereby leading to a substantial burden for individuals, families, and society. During adolescence, the prefrontal cortex undergoes extensive structural and functional changes. Recent work suggests that frontolimbic development in depressed adolescents is delayed or aberrant. The judicious application of non-invasive brain stimulation techniques to the prefrontal cortex may present a promising opportunity for durable interventions in adolescent depression. Transcranial direct current stimulation (tDCS applies a low-intensity, continuous current that alters cortical excitability. While this modality does not elicit action potentials, it is thought to manipulate neuronal activity and neuroplasticity. Specifically, tDCS may modulate N-methyl-d-aspartate receptors and L-type voltage-gated calcium channels and effect changes through long-term potentiation or long-term depression-like mechanisms. This mini-review considers the neurobiological rationale for developing tDCS protocols in adolescent depression, reviews existing work in adult mood disorders, surveys the existing tDCS literature in adolescent populations, reviews safety studies, and discusses distinct ethical considerations in work with adolescents.

    2013-03-01

    The diagnosis of personality disorders in adolescents has been a topic of debate in recent years. This manuscript reviews the case of an adolescent girl admitted for a medium length combined inpatient and partial hospitalization program. This program has developed protocols to assess for Axis I and II pathology as well as various psychological processes. Comprehensive outcome measures were administered to the patient at discharge and follow-up. Diagnosis of a personality disorder in adolescence appears to be associated with psychological processes usually identified in adults. Against the background of an emerging debate about the need to reform a culture of ultra-short inpatient care, this case study provides some support for more thorough assessment, diagnosis, and treatment of adolescents who appear to have comorbid Axis I and II disorders.

  16. A Study of Shared-Memory Mutual Exclusion Protocols Using CADP

    Mateescu, Radu; Serwe, Wendelin

    Mutual exclusion protocols are an essential building block of concurrent systems: indeed, such a protocol is required whenever a shared resource has to be protected against concurrent non-atomic accesses. Hence, many variants of mutual exclusion protocols exist in the shared-memory setting, such as Peterson's or Dekker's well-known protocols. Although the functional correctness of these protocols has been studied extensively, relatively little attention has been paid to their non-functional aspects, such as their performance in the long run. In this paper, we report on experiments with the performance evaluation of mutual exclusion protocols using Interactive Markov Chains. Steady-state analysis provides an additional criterion for comparing protocols, which complements the verification of their functional properties. We also carefully re-examined the functional properties, whose accurate formulation as temporal logic formulas in the action-based setting turns out to be quite involved.

    Coping is a psychological process that prompts the individual to adapt to stressful situations. The Adolescent Coping Scale is a widely used research and clinical tool. This study aimed to develop a Portuguese version of the Adolescent Coping Scale and to analyze the strategies and coping styles of young people in our sample. An anonymous questionnaire comprising the Adolescent Coping Scale was submitted and replied by 1 713 students (56% female, from 12 to 20 years, average age 16) The validity study of the scale included: principal component and reliability analysis; confirmatory analysis using structural equation modelling Subsequently, a gender comparison of both the strategies and the coping styles was conducted through independent samples t tests. The final structure of the Adolescent Coping Scale adaptation retained 70 items assessing 16 coping strategies grouped into three major styles. The scales showed good internal consistency (Cronbach alpha values between 0.63. and 0.86, with the exception of one dimension that as shown a value of 0.55) and the confirmatory model showed a good fit (goodness of fit index values between 0.94 e 0.96). Two coping strategies were eliminated on statistical grounds (insufficient saturations of items in the corresponding dimensions). We found that the style of coping focused on problem solving is the most used by youths from our sample, in both sexes. Females had higher mean values in non-productive coping style and reference to others. This adapted version has high similarity with the original scale, with expectable minor changes, given that coping is influenced by cultural, geographical and socio-economic variables. The present study represents an important part of the validation protocol Portuguese Adolescent Coping Scale, including its linguistic adaptation and its internal consistency and factor structure studies.

    Methylphenidate is the most frequently used medication for the treatment of attention-deficit/hyperactivity disorder (ADHD) in Europe. Following concerns about its safety, the European Commission called for research into the long-term effects of methylphenidate on children and adolescents with ADHD. The Attention Deficit Hyperactivity Disorder Drugs Use Chronic Effects (ADDUCE) research programme was designed to address this call. At the heart of this programme is a 2-year longitudinal naturalistic pharmacovigilance study being conducted in 27 European sites. 3 cohorts of children and adolescents (aged 6-17) living in the UK, Germany, Italy and Hungary are being recruited:Group 1 (Medicated ADHD): 800 ADHD medication-naive children and adolescents with a clinical diagnosis of ADHD about to start methylphenidate treatment for the first time.Group 2 (Unmedicated ADHD): 400 children and adolescents with a clinical diagnosis of ADHD who have never been treated with ADHD medication and have no intention of beginning medication.Group 3 (Non-ADHD): 400 children and adolescents without ADHD who are siblings of individuals in either group 1 or 2.All participants will be assessed 5 times during their 2-year follow-up period for growth and development, psychiatric, neurological and cardiovascular health. The primary outcome measure will be the height velocity SD score. Ethical approval for the study has been granted by the East of Scotland Research Ethics Service. Following this approval, patient information leaflets and consent forms were translated as necessary and submissions made by lead sites in each of the other 3 countries to their own ethics committees. Following ethical approval in each country, local ethical permissions at each site were sought and obtained as needed.

    Full Text Available Abstract Background Suicide is the leading cause of death among Japanese adolescents, and they may commit suicide differently from adults. However, there are few studies in medical-based data concerning adolescent patients seriously attempting suicide. We aimed to explore the characteristics of serious suicide attempts in Japanese adolescents, comparing them with those in adults. Methods We investigated adolescents who seriously attempted suicide and were treated at the Critical Care Medical Center (CCMC of Nippon Medical School Hospital between 2000 and 2010, and we compared them with adult suicide attempters treated during 2009. We retrospectively studied medical records and collected clinical data and socio-demographic factors, including age, sex, psychiatric symptoms or diagnosis, methods of suicide attempt, motives for suicide attempt, previous deliberate self-harm, previous psychiatric history, parent loss experience, and previous psychiatric history in the family. Results Adolescent attempters were 15 males and 44 females, 13 to 18 years old (mean 16.39. Adult attempters were 37 males and 65 females, 19 to 79 years old (mean 39.45. In comparison to adult attempters, adolescent attempters were more frequently diagnosed with Borderline Personality Disorder (BPD, had more school problems and parent loss experience, but they had less financial problems. Gender differences between adolescents and adults were examined, and male adolescent attempters were found to be more frequently diagnosed with schizophrenia and had less financial problems than their adult counterparts, while female adolescent attempters were more frequently diagnosed with BPD, had more school problems and parent loss, but they had less previous psychiatric history than their adult counterparts. Conclusions Our findings indicated that adolescent attempters were more frequently diagnosed with BPD and had more school problems and parent loss experience but had less financial

    Full Text Available Earthquakes, which can cause widespread territorial and socio-economic destruction, are life-threatening, unexpected, unpredictable, and uncontrollable events caused by the shaking of the surface of the earth. The psychological consequences, such as PTSD, anxiety, depression, and suicidal ideation, are well-known to clinicians and researchers. This study was conducted with the aim of evaluating the use of the Eye Movement Desensitization and Reprocessing (EMDR Integrative Group Treatment Protocol on a sample of adolescents, after the earthquake in Central Italy on 24 August 2016. The objective of the EMDR intervention was to reduce PTSD symptoms. Before and after EMDR, specific assessment to find changes in PTSD symptoms was made using the Impact of Event Scale-Revised and through the analyses of the Subjective Units of Disturbance. The EMDR treatment was given in three sessions (T1, T2, and T3, each lasting 90 min, and the results at follow-up phase (T4 were also monitored. The results are very encouraging, showing significantly reduced PTSD symptoms in the majority of the subjects. The clinical implications and limitations will be discussed.

    2016-01-01

    This purpose of this study was to provide a theoretical account of how adolescents aged 13 to 18 years process the experience of having an ostomy. Qualitative study using grounded theory design. The sample comprised of 12 English-speaking adolescents aged 13-18 years: 10 with an ostomy and 2 with medical management of their disease. Respondents completed audio-recorded interviews that were transcribed verbatim. Data were analyzed using the constant comparative method until data saturation occurred. Dedoose, a Web-based qualitative methods management tool, was used to capture major themes arising from the data. Study results indicate that for adolescents between 13 and 18 years of age, processing the experience of having an ostomy includes concepts of the "physical self" and "social self" with the goal of "normalizing." Subcategories of physical self include (a) changing reality, (b) learning, and (c) adapting. Subcategories of social self include (a) reentering and (b) disclosing. This study sheds light on how adolescents process the experience of having an ostomy and how health care providers can assist adolescents to move through the process to get back to their desired "normal" state. Health care providers can facilitate the adolescent through the ostomy experience by being proactive in conversations not only about care issues but also about school and family concerns and spirituality. Further research is needed in understanding how parents process their adolescents' ostomy surgery experience and how spirituality assists adolescents in coping and adjustment with body-altering events.

    Physical activity levels are low amongst adolescent girls, and this population faces specific barriers to being active. Peer influences on health behaviours are important in adolescence and peer-led interventions might hold promise to change behaviour. This paper describes the protocol for a feasibility cluster randomised controlled trial of Peer-Led physical Activity iNtervention for Adolescent girls (PLAN-A), a peer-led intervention aimed at increasing adolescent girls' physical activity levels. A two-arm cluster randomised feasibility trial will be conducted in six secondary schools (intervention n  = 4; control n  = 2) with year 8 (12-13 years old) girls. The intervention will operate at a year group level and consist of year 8 girls nominating influential peers within their year group to become peer-supporters. Approximately 15 % of the cohort will receive 3 days of training about physical activity and interpersonal communication skills. Peer-supporters will then informally diffuse messages about physical activity amongst their friends for 10 weeks. Data will be collected at baseline (time 0 (T0)), immediately after the intervention (time 1 (T1)) and 12 months after baseline measures (time 2 (T2)). In this feasibility trial, the primary interest is in the recruitment of schools and participants (both year 8 girls and peer-supporters), delivery and receipt of the intervention, data provision rates and identifying the cost categories for future economic analysis. Physical activity will be assessed using 7-day accelerometry, with the likely primary outcome in a fully-powered trial being daily minutes of moderate-to-vigorous physical activity. Participants will also complete psychosocial questionnaires at each time point: assessing motivation, self-esteem and peer physical activity norms. Data analysis will be largely descriptive and focus on recruitment, attendance and data provision rates. The findings will inform the sample size required for a

    2014-06-01

    Full Text Available Aim: The orthodontic movement is associated with a process of tissue remodeling together with the release of several chemical mediators in periodontal tissues. Each mediator is a potential marker of tooth movement and expresses biological processes as: tissue inflammation and bone remodeling. Different amounts of every mediator are present in several tissues and fluids of the oral cavity. Therefore, there are different methods that allow sampling with several degrees of invasiveness. Chemical mediators are also substances of different molecular nature, and multiple kind of analysis methods allow detection. The purpose of this study was to draft the best research protocol for an optimal study on orthodontic movement efficiency. Methods: An analysis of the international literature have been made, to identify the gold standard of each aspect of the protocol: type of mediator, source and method of sampling and analysis method. Results: From the analysis of the international literature was created an original research protocol for the study and the assessment of the orthodontic movement, by using the biomarkers of the tooth movement. Conclusions: The protocol created is based on the choice of the gold standard of every aspect already analyzed in the literature and in existing protocols for the monitoring of orthodontic tooth movement through the markers of tooth movement. Clinical trials re required for the evaluation and validation of the protocol created.

    Full Text Available Internet Addiction (IA is associated with adverse psychosocial development and mental disorders. The study aims were to evaluate the psychosocial profiles and psychiatric comorbidities associated with IA among adolescents. A case-control study was conducted among 129 adolescents in the outpatient setting of the Adolescent Health Unit of the Second University Department of Pediatrics in Athens, Greece. The case group consisted of 86 adolescents with IA as evaluated following psychiatric interview with two independent examiners. The control group consisted of 43 adolescents without IA, frequency matched for age and gender with case group participants. The study findings indicated that adolescents with IA were significantly more likely to have divorced parents (p = 0.012 and/or dysfunctional familial relationships (p < 0.0001. The proportion of adolescents with poor academic performance (p < 0.0001 and unexcused school absences (p = 0.004 was greater among those with IA. Moreover, approximately two-thirds of the adolescents with IA were engaged in high-risk behaviors (p < 0.0001. Finally, adolescents with IA were 3.89 times more likely to present with comorbid psychiatric conditions (CI 95%: 1.19–12.70, including depression (10.5 vs. 0%; p = 0.022. Adolescent IA is associated with deterred familial functions, poor academic performance, engagement in high-risk behaviors, and an augmented likelihood for depression.

    2012-09-01

    Full Text Available Abstract Background Mid to late adolescence is characterised by a vulnerability to problematic substance use since the consumption of alcohol and illicit drugs is frequently initiated and increased in this life period. While the detrimental long- and short-term effects of problematic consumption patterns in adolescence pose a major public health concern, current prevention programs targeting alcohol- and other substance-using adolescents are scarce. The study described in this protocol will test the effectiveness of a web-based brief intervention aimed at reducing problematic alcohol use and promoting abstinence from illegal drugs in adolescents with risky substance use aged 16 to 18 years old in four EU-countries. Methods/design To determine the effectiveness of our web-BI, we apply a two-arm randomized controlled trial (RCT study design, with baseline assessment at study entry and a three month follow-up assessment. Adolescents aged 16 to 18 years from Belgium, the Czech Republic, Germany, and Sweden will be randomly assigned to either the fully electronically delivered brief intervention group (N = 400 or an assessment only control group (N = 400 depending on their screening for risky substance use (using the CRAFFT. Recruitment, informed consent, randomization, intervention and follow-up will be implemented online. Primary outcomes are reductions in frequency and quantity of use of alcohol and drugs other than alcohol over a 30 day period, as well as consumption per typical occasion. Secondary outcomes concern changes in substance use related cognitions including the constructs of the Theory of Planned Behaviour, implementation intentions, and stages of change. Moreover the study addresses a number of moderator variables, including age of first use, general psychopathology and quality of parent–child relationship. Discussion The trial is expected to contribute to the growing literature on theory- and web-based brief interventions

    Full Text Available BACKGROUND Electroconvulsive Therapy (ECT among adolescent psychiatric patient is rarely used and studies in this regard are also rare, while its need is of great importance. Aim of this study was to study the prevalence of ECT in common psychiatric illnesses among adolescent age group, where it is indicated and outcome of ECT in those psychiatric patients. MATERIALS AND METHODS All data were collected retrospectively from the chart review for those adolescents aged between 12 to 18 years who received ECT during the period of 2008 - 2012. During the study period a total of 554 patients received ECT, among whom 104 were adolescents. RESULTS Adolescent patients were 18.77% in the whole ECT sample; the average age of the adolescents was 16.33 years and number of patients were more with older age. Among all the patients, 48.08% had positive family history of mental illness and 81.73% were from lower Socioeconomic Class. The use of ECT was more with schizophrenia (n= 63, 60.57% and acute and transient psychotic disorder (n= 30, 28.85%. The most common indication was agitation and aggression (n= 29, 27.88% followed by poor medication response (n= 19, 18.27%. Good response is found in most of the cases (n= 88, 84.62%, only a few percentage of cases showed minor and transient adverse event. CONCLUSION The result of our study suggests that prevalence of ECT among adolescent psychiatric patients is quite high and ECT is a safe and effective method of treatment in the adolescent psychiatric patients, especially those patients who are severely ill and poorly responding to medication.

Three study groups were selected from three different girls’ school by random sampling method. Statistical analysis was done with SPSS. Result & Conclusion: Overall prevalence was 58.4% among adolescent schoolgirls. Prevalence of anemia was dependent on the knowledge about prevention of anemia, literacy level, food habits, birth order & also frequency of Iron rich source viz. green leafy vegetable & non vegetarian diet. While there was no significant relation of anemia with duration of menstrual flow but there was significant (P<0.05 difference in number of anaemic cases with age at menarche i.e. with higher age at menarche; there was more chances of anemia. Level of anemia was higher (p<0.05 in early adolescent (10 -13 Years age group (81% as compared to middle (58.3% and late adolescent (17-19 years age group girls (48.7%.

    Some sedatives used in children and adolescents can affect memory function. Memory impairment of traumatic experience can minimize the chance of future psychological trauma. Knowledge about the potential of different sedatives to produce amnesia can help in the decision-making process of choosing a sedative regimen. The aim of this systematic review is to evaluate the effect of different sedatives on memory of perioperative events in children and adolescents. Electronic databases and other sources, such as trial registers, gray literature, and conference abstracts will be searched. Randomized controlled trials will be included that assess memory of perioperative events in children and adolescents 2-19 years old receiving sedative drugs as premedication or as agents for procedural sedation in a medical or dental settings. The outcomes will be loss of memory after and before sedative administration (anterograde and retrograde amnesia). Two independent reviewers will perform screening, study selection, and data extraction. Disagreement at all levels will be resolved by consensus or by involving a third reviewer. Assessment of the risk of bias of included studies will be performed according to "Cochrane Collaboration's Tool for Assessing Risk of Bias in Randomized Trials." Clinical and methodological heterogeneity across studies will be evaluated to determine if it is possible to combine or not combine study results in a meta-analysis. To the best of our knowledge, there is no systematic review that specifically addresses this question. Findings from the review will be useful in the decision-making process about the best sedative for minimizing recall of the medical/dental event and possible psychological trauma.

    Full Text Available Abstract Background An inverse social gradient in overweight among adolescents has been shown in developed countries, but few studies have examined whether weight gain and the development of overweight differs among adolescents from different socioeconomic groups in a longitudinal study. The objective was to identify the possible association between parental socioeconomic position, weight change and the risk of developing overweight among adolescents between the ages 15 to 21. Methods Prospective cohort study conducted in Denmark with baseline examination in 1996 and follow-up questionnaire in 2003 with a mean follow-up time of 6.4 years. A sample of 1,656 adolescents participated in both baseline (mean age 14.8 and follow-up (mean age 21.3. Of these, 1,402 had a body mass index (BMI = weight/height2kg/m2 corresponding to a value below 25 at baseline when adjusted for age and gender according to guidelines from International Obesity Taskforce, and were at risk of developing overweight during the study period. The exposure was parental occupational status. The main outcome measures were change in BMI and development of overweight (from BMI = 25. Results Average BMI increased from 21.3 to 22.7 for girls and from 20.6 to 23.6 in boys during follow-up. An inverse social gradient in overweight was seen for girls at baseline and follow-up and for boys at follow-up. In the full population there was a tendency to an inverse social gradient in the overall increase in BMI for girls, but not for boys. A total of 13.4% developed overweight during the follow-up period. Girls of lower parental socioeconomic position had a higher risk of developing overweight (OR's between 4.72; CI 1.31 to 17.04 and 2.03; CI 1.10-3.74 when compared to girls of high parental socioeconomic position. A tendency for an inverse social gradient in the development of overweight for boys was seen, but it did not meet the significance criteria Conclusions The levels of overweight and

    To understand adolescents' and parents' willingness to participate (WTP) in a hypothetical phase I prevention study of sexually transmitted infections, discordance within adolescent-parent dyads, and expectations of each other during decision-making. Adolescent-parent dyads were recruited to participate in a longitudinal study about research participation attitudes. Adolescents (14-17 years old) and their parents (n = 301 dyads) participated. None. Individual interviews at baseline assessed WTP on a 6-level Likert scale. WTP was dichotomized (willing/unwilling) to assess discordance. WTP was reported by 60% (182 of 301) of adolescents and 52% (156 of 300) of parents. In bivariate analyses, older adolescent age, sexual experience, and less involvement of parents in research processes were associated with higher level of WTP for adolescents; only sexual experience remained in the multivariable analysis. For parents, older adolescent age, perceived adolescent sexual experience, and conversations about sexual health were significant; only conversations remained. Dyadic discordance (44%, 132 of 300) was more likely in dyads in which the parent reported previous research experience, and less likely when parents reported higher family expressiveness. Adolescents (83%, 248 of 299) and parents (88%, 263 of 300) thought that the other would have similar views, influence their decision (adolescents 66%, 199 of 300; parents 75%, 224 of 300), and listen (adolescents 90%, 270 of 300; parents 96%, 287 of 300). There were no relationships between these perceptions and discordance. Inclusion of adolescents in phase I clinical trials is necessary to ensure that new methods are safe, effective, and acceptable for them. Because these trials currently require parental consent, strategies that manage adolescent-parent discordance and support adolescent independence and parental guidance are critically needed.

    A number of studies have concluded that parents of children with ASD experience high levels of parenting stress. However, little is known about their parenting behaviors. Especially few studies investigated parenting in adolescence, although this period is associated with additional challenges for both adolescents and their parents. In the present study, a multi-method approach was used, combining data from a self-report questionnaire and observation of mother-child interactions during different semi-structured (e.g., inventing and building a vehicle of the future with construction toys) and structured tasks (e.g., solving marble maze). Linear mixed models (LMM) were used to compare the means of parenting behaviors among mothers of adolescents with (n = 44) and without ASD (n = 38), aged 12 to 16 years old. During the observations, mothers of adolescents with ASD showed more sensitivity and creativity, compared to the general population control group. In addition, mothers in the ASD group reported on the self-report questionnaire to adapt the environment more, for example, by establishing routines. Furthermore, this study investigated the role of maternal characteristics, that is, ASD characteristics and parenting stress. Parenting stress was associated with less self-reported positive parenting. Higher levels of ASD characteristics of the mother were related to more negativity and less sensitivity during the observation, and more self-reported harsh punishment and adapting the environment. This study additionally examined whether the impact of these maternal characteristics was the same across the two groups. Whereas group by parenting stress interaction effects were not significant for any of the observed and self-reported parenting behaviors, significant group by ASD characteristics interaction effects were noticed for self-reported harsh punishment and adapting the environment.

    Full Text Available Background:KwaZulu-Natal had no dedicated in-patient adolescent psychiatric service during the study period and adolescents were admitted to general psychiatric wards. Aim of Study: This is a descriptive review of adolescents admitted with psychotic symptoms to a psychiatric hospital. It aims to describe their demographic profile, associated risk factors, clinical profile and management strategies utilized. Method: The files of all adolescent patients with psychotic symptoms, aged twelve to eighteen years old, admitted to a psychiatric hospital from July 2005 to June 2007 were reviewed. Results: 70 adolescents with psychosis were admitted to adult psychiatric wards over the 2 year period. The age range was 13 to 18 years old. 80% of the adolescent patients were male, 37% reported a positive family history of mental illness, 50% smoked nicotine and 61.4% reported cannabis use. The most common diagnoses were schizophrenia (30% and schizophreniform disorder (27.1%. 85.5%(60 of adolescent patients had a trial on a first generation antipsychotic and 10 patients were initiated on a second generation antipsychotic de- novo. The average length of stay in hospital was 27.8 days. 40% defaulted follow up post discharge. Conclusion: Schizophrenia was the most common diagnosis. There were high rates of cannabis use. The adolescents were managed in psychiatric wards for significant periods and the majority of patients were initiated on first-generation antipsychotics. There is a need to develop specialized inpatient adolescent psychiatric facilities and services, as well as to address the issues of co-morbid substance use and non-adherence to treatment.

    Overweight youngsters are better in absolute strength exercises than their normal-weight counterparts; a physiological phenomenon with promising psychological impact. In this paper we describe the study protocol of the Dutch, school-based program 'Focus on Strength' that aims to improve body composition of 11-13 year old students, and with that to ultimately improve their quality of life. The development of this intervention is based on the Intervention Mapping (IM) protocol, which starts from a needs assessment, uses theory and empirical research to develop a detailed intervention plan, and anticipates program implementation and evaluation. This novel intervention targets first year students in preparatory secondary vocational education (11-13 years of age). Teachers are the program implementers. One part of the intervention involves a 30 % increase of strength exercises in the physical education lessons. The other part is based on Motivational Interviewing, promoting autonomous motivation of students to become more physically active outside school. Performance and change objectives are described for both teachers and students. The effectiveness of the intervention will be tested in a Randomized Controlled Trial in 9 Dutch high schools. Intervention Mapping is a useful framework for program planning a school-based program to improve body composition and motivation to exercise in 11-13 year old adolescents by a "Focus on Strength".

    Full Text Available Context: Adolescence is a period of biological, cognitive and social transition of such magnitude and rapidity that it is no surprise to find that it is associated with the onset or exacerbation of a number of health-related problems. It is the level of self-awareness among adolescents, which enables them to see where their thoughts and emotions take them. Aims: The aim of this study was to assess the extent of awareness regarding adolescent changes/problems among school going adolescents. Settings and Design: It was a cross-sectional study and was carried out in Block Beri, District, Jhajjar (Haryana. Materials and Methods: A sample of 320 adolescent students of 9 th -12 th classes (80 from each school were selected from four randomly chosen large Government senior secondary schools with strength of more than 250 students (two girls and two boys/co-ed senior secondary schools. Data were collected on predesigned, pre-tested and semi-structured schedules by conducting in-depth interviews of selected study adolescents by the investigator. Statistical Analysis Used: Percentages, proportions, Chi-square test, Chi-square test with Yate′s correction and t-test. Results: Out of 320, 212 (66.3% study adolescents were aware of at least one adolescent change(s whereas, when probed and further asked to enumerate the changes taking place in them, 272/320 (85% adolescents could narrate at least one such change. Out of those 272, 24 (8.82% (95% CI 6.0-12.79 adolescents either did not consider these changes as normal or they did not know whether the changes were normal or abnormal. Conclusions: Adolescents greatly lack correct information related to their bodies′ physiological, psychological and sexual changes. There is an urgent need for regular adolescent friendly information, education and communication activities covering different aspects of adolescent knowledge needs/problems.

    Full Text Available Alcohol, psychoactive substance, harmful to health, has been widely accepted and consumed by society in a premature manner. The Brazilian contemporaneous reality has demonstrated a high number of adolescents who consume alcohol on regularly basis, and nowadays, its damages start to be evident, hence the importance of contextualizing this issue in relation to adolescents. This study aims to determine the profile of alcohol consumption in adolescent students of a public high school in a city of the inland of Bahia, Brazil. It is a descriptive study with quantitative approach, conducted with 98 male and female students, and a structured questionnaire used to collect data, which was analyzed with aid of descriptive statistics. The survey was approved by the Ethics inResearch Committee Involving Human Beings, of the State University of Southwest Bahia –campus of Jequié-Bahia, Brazil under Protocol 179/2009. It was perceived that most of the teenagers had already consumed alcohol prematurely, with minimal difference between male and female gender. Several of these adolescents continue consuming too much and too often, influenced by friends, family and media. It can be concluded that it is imperative to insert educational methodological proposals at schools which shouldinstruct about premature and indiscriminate alcohol consumption, addressing principally risk factors and possible biopsychosocial complications.

    Previous neuroimaging studies link both alcohol use disorder (AUD) and early adversity to neurobiological differences in the adult brain. However, the association between AUD and childhood adversity and effects on the developing adolescent brain are less clear, due in part to the confound of psychiatric comorbidity. Here we examine early life adversity and its association with brain volume in a unique sample of 116 South African adolescents (aged 12-16) with AUD but without psychiatric comorbidity. Participants were 58 adolescents with DSM-IV alcohol dependence and with no other psychiatric comorbidities, and 58 age-, gender- and protocol-matched light/non-drinking controls (HC). Assessments included the Childhood Trauma Questionnaire (CTQ). MR images were acquired on a 3T Siemens Magnetom Allegra scanner. Volumes of global and regional structures were estimated using SPM8 Voxel Based Morphometry (VBM), with analysis of covariance (ANCOVA) and regression analyses. In whole brain ANCOVA analyses, a main effect of group when examining the AUD effect after covarying out CTQ was observed on brain volume in bilateral superior temporal gyrus. Subsequent regression analyses to examine how childhood trauma scores are linked to brain volumes in the total cohort revealed a negative correlation in the left hippocampus and right precentral gyrus. Furthermore, bilateral (but most significantly left) hippocampal volume was negatively associated with sub-scores on the CTQ in the total cohort. These findings support our view that some alterations found in brain volumes in studies of adolescent AUD may reflect the impact of confounding factors such as psychiatric comorbidity rather than the effects of alcohol per se. In particular, early life adversity may influence the developing adolescent brain in specific brain regions, such as the hippocampus.

    Full Text Available Functional gastrointestinal disorders (FGID, including irritable bowel syndrome, functional dyspepsia and functional abdominal pain, are common in adolescents and are associated with substantially decreased quality of life. Cognitive behavior therapy for children and adolescents with FGID is one of few treatments that have shown effect, but treatment access is limited. In adults with irritable bowel syndrome, exposure-based internet-delivered CBT (ICBT leads to reduced symptoms and increased quality of life, but studies in children are lacking. This open pilot aimed to evaluate feasibility and the potential efficacy of an exposure-based ICBT-program for adolescents with pain-predominant FGID. Twenty-nine adolescents (age 13–17, with FGID were included. The ICBT-program lasted for 8 weeks with weekly online therapist support. The protocol for adolescents included exposure to abdominal symptoms, while the protocol for parents aimed at increasing parents' attention to adolescent healthy behaviors. Assessment points were baseline, post-treatment and 6-month follow-up. The primary outcome was the Gastrointestinal Symptoms Rating Scale-IBS (GSRS-IBS. Effect sizes were calculated using Cohen's d in an intent to treat analysis. GSRS-IBS improved significantly from baseline to post-treatment (mean difference 6.48; 95% CI [2.37–10.58] and to follow-up (mean difference 7.82; 95% CI [3.43–12.21], corresponding to moderate effect sizes (within-group Cohen's d = 0.50; 95% CI [0.16–0.84] and d = 0.63; 95% CI [0.24–1.02], respectively. Treatment adherence was high with 22 of 29 (76% adolescents completing the entire treatment period. High adherence indicates acceptability of format and content, while symptomatic improvement suggests potential efficacy for this ICBT intervention in adolescents with FGID.

    This research aims to understand the circumstances associated with school dropout in a cohort of Puerto Rican adolescents. The study collected data from adolescents and their parents. Information related to school dropout among adolescents was obtained from the second year follow-up data from the longitudinal study funded by NIDA "Risky Families Embedded in Risky Environments" (Grant No. R01 DA 15301). Data was collected employing a self-administered and a face-to-face interview protocol. Prediction of school dropout was assessed throughout adolescent characteristics, family background, school experiences and behaviors. During the second follow-up, two years after the baseline assessment, approximately 6.2% of the adolescents reported dropping out from school. Logistic regression analysis indicates that older adolescents (OR = 6.6, 1.37-31.67), whose mother used drugs during pregnancy (OR = 4.9, 1.31-17.91), who reported high rates of absenteeism (OR = 4.8, 1.63-14.13), high school grade retention (OR = 3.7, 1.14-12.05), and attended school where teachers were attacked or wounded by students (O R =7.0, 1.44-34.17) were more likely to dropout of school. : These findings emphasize the need to further understand the effects of different elements of adolescents' environment such as family and school. It has been posited that dropping out of school is a process whose characteristics can be detected long before it occurs. The fact that students who dropout are more likely to report skip classes and grade retention can be relevant elements in prevention and early intervention for teachers and other school personnel.

    Using a qualitative method, the purpose of this study was to: (1) obtain information directly from the adolescents on their attitudes and knowledge regarding emergency contraception; and (2) investigate the presence of differences between male and female participants' attitudes and knowledge. This study consisted of 24 single-sex focus groups with 160 adolescents (male = 46.3% (74 of 160); female = 53.7% (86 of 160)) aged 15-19 years conducted among high schools in 3 regions of Italy. Data were analyzed through thematic analysis taking into account gender differences and 2 main themes emerged. The first was labeled "Adolescents' attitudes toward emergency contraception" and it was divided into 3 subthemes: You should be aware; It's a life line; and Everything but a child. The second theme was labeled "Adolescents' knowledge toward emergency contraception" and it was divided into 3 subthemes: False myths; Baseline information; and Just take it. Italian adolescents believed it is important to prevent the risk of unprotected sex by using contraceptive methods and their motivation to use emergency contraception is related to critical attitudes toward the consequences of irresponsible/ineffective contraception. Although adolescents have an awareness of emergency contraception, more comprehensive knowledge is needed. These findings can inform specific interventions aimed at educating adolescents in need of emergency contraception. Copyright © 2016 North American Society for Pediatric and Adolescent Gynecology.

    Osteoporosis is a skeletal disease associated with high morbidity, mortality and increased economic costs. Early prevention during adolescence appears to be one of the most beneficial practices. Exercise is an effective approach for developing bone mass during puberty, but some sports may have a positive or negative impact on bone mass accrual. Plyometric jump training has been suggested as a type of exercise that can augment bone, but its effects on adolescent bone mass have not been rigorously assessed. The aims of the PRO-BONE study are to: 1) longitudinally assess bone health and its metabolism in adolescents engaged in osteogenic (football), non-osteogenic (cycling and swimming) sports and in a control group, and 2) examine the effect of a 9 month plyometric jump training programme on bone related outcomes in the sport groups. This study will recruit 105 males aged 12-14 years who have participated in sport specific training for at least 3 hours per week during the last 3 years in the following sports groups: football (n = 30), cycling (n = 30) and swimming (n = 30). An age-matched control group (n = 15) that does not engage in these sports more than 3 hours per week will also be recruited. Participants will be measured on 5 occasions: 1) at baseline; 2) after 12 months of sport specific training where each sport group will be randomly allocated into two sub-groups: intervention group (sport + plyometric jump training) and sport group (sport only); 3) exactly after the 9 months of intervention; 4) 6 months following the intervention; 5) 12 months following the intervention. Body composition (dual energy X-ray absorptiometry, air displacement plethysmography and bioelectrical impedance), bone stiffness index (ultrasounds), physical activity (accelerometers), diet (24 h recall questionnaire), pubertal maturation (Tanner stage), physical fitness (cardiorespiratory and muscular), bone turnover markers and vitamin D will be measured at each visit.

    In adolescence, youth antisocial behaviors reach a peak. Parents can use different strategies, such as parental solicitation and control, to monitor their children’s activities and try to prevent or reduce their antisocial behaviors. However, it is still unclear if, and for which adolescents, these parental monitoring behaviors are effective. The aim of this study was to examine if the impact of parental solicitation and control on adolescent antisocial behaviors depends on adolescent empathy. In order to comprehensively address this aim, we tested the moderating effects of multiple dimensions (affective and cognitive) of both trait and state empathy. Participants were 379 Dutch adolescents (55.9% males) involved in a longitudinal study with their fathers and mothers. At T1 (conducted when adolescents were 17-year-old) adolescents filled self-report measures of antisocial behaviors and trait empathy during one home visit, while their state empathy was rated during a laboratory session. Furthermore, parents reported their own monitoring behaviors. At T2 (conducted 1 year later, when adolescents were 18-year-old), adolescents reported again on their antisocial behaviors. Moderation analyses indicated that both affective and cognitive state empathy moderated the effects of parental solicitation on adolescent antisocial behaviors. Results highlighted that solicitation had unfavorable effects on antisocial behaviors in adolescents with high empathy whereas the opposite effect was found for adolescents with low empathy. In contrast, neither state nor trait empathy moderated the effects of control on adolescent antisocial behaviors. Theoretical and practical implications of these findings are discussed.

Aims: This study aims to study the effect of implementing a protocol-based pain management in the ED on (1 time to analgesia and (2 adequacy of analgesia obtained. Settings and Design: Cross-sectional study in the ED. Methods: Patients aged 18–65 years of age with pain of numeric rating scale (NRS ≥4 were included. A series of 100 patients presenting before introduction of the protocol-based pain management were grouped “pre-protocol,” and managed as per existing practice. Following this, a protocol for management of all patients presenting to ED with pain was implemented. Another series of 100 were grouped as “post-protocol” and managed as per the new pain management protocol. The data of patients from both the groups were collected and analyzed. Statistical Analysis Used: Descriptive statistical tests such as percentage, mean and standard deviation and inferential statistical tests such as Pearson coefficient, Student's t-test were applied. Differences were interpreted as significant when P < 0.05. Results: Mean time to administer analgesic was significantly lesser in the postprotocol group (preprotocol 20.30 min vs. postprotocol 13.05 min; P < 0.001. There was significant difference in the pain relief achieved (change in NRS between the two groups, with greater pain relief achieved in the postprotocol group (preprotocol group 4.6800 vs. postprotocol group 5.3600; P < 0.001. Patients' rating of pain relief (assessed on E5 scale was significantly higher in the postprotocol group (preprotocol 3.91 vs. postprotocol 4.27; P = 0.001. Patients' satisfaction (North American Spine Society scale with the overall treatment was also compared and found to be significantly higher in postprotocol group (mean: preprotocol 1.59 vs. postprotocol 1.39; P = 0.008.

    To investigate the effects of sleep restriction (7 nights of 5 h time in bed [TIB]) on cognitive performance, subjective sleepiness, and mood in adolescents. A parallel-group design was adopted in the Need for Sleep Study. Fifty-six healthy adolescents (25 males, age = 15-19 y) who studied in top high schools and were not habitual short sleepers were randomly assigned to Sleep Restriction (SR) or Control groups. Participants underwent a 2-w protocol consisting of 3 baseline nights (TIB = 9 h), 7 nights of sleep opportunity manipulation (TIB = 5 h for the SR and 9 h for the control groups), and 3 nights of recovery sleep (TIB = 9 h) at a boarding school. A cognitive test battery was administered three times each day. During the manipulation period, the SR group demonstrated incremental deterioration in sustained attention, working memory and executive function, increase in subjective sleepiness, and decrease in positive mood. Subjective sleepiness and sustained attention did not return to baseline levels even after 2 recovery nights. In contrast, the control group maintained baseline levels of cognitive performance, subjective sleepiness, and mood throughout the study. Incremental improvement in speed of processing, as a result of repeated testing and learning, was observed in the control group but was attenuated in the sleep-restricted participants, who, despite two recovery sleep episodes, continued to perform worse than the control participants. A week of partial sleep deprivation impairs a wide range of cognitive functions, subjective alertness, and mood even in high-performing high school adolescents. Some measures do not recover fully even after 2 nights of recovery sleep. A commentary on this article appears in this issue on page 497. © 2016 Associated Professional Sleep Societies, LLC.

    Physical activity (PA) reduces symptoms of Attention Deficit Hyperactivity Disorder (ADHD); interventions to increase PA may improve functioning and health for adolescents with ADHD. Mobile health (mHealth) technology and social media constitute promising interactive modalities for engaging adolescents-who are at highest risk for ADHD treatment drop-out-in interventions to increase PA. The current pilot study evaluated feasibility and acceptability of an innovative intervention incorporating an mHealth-linked wearable activity tracker (Fitbit Flex) and a Facebook group to increase PA among adolescents with ADHD. 11 adolescents diagnosed with ADHD (age 14-18, m = 15.5; 54% female) participated in a 4-week trial utilizing the Fitbit Flex in conjunction with (1) weekly personalized step count goals (2) social support through a Facebook group and (3) daily text messages about PA. The study took place in the greater Seattle, Washington area in the fall of 2015. Adolescents completed online surveys twice per week to rate their ADHD symptoms and positive and negative mood states, and parents rated adolescent ADHD symptoms weekly. Participants were adherent to the study protocol and acceptability of the intervention was high. Linear mixed models indicated that participants significantly increased their average weekly steps over the course of the study and demonstrated improvements in both adolescent and parent-reported ADHD Inattentive symptoms. Results indicate that this mHealth intervention is engaging and promising for increasing PA among adolescents with ADHD, and warrant further study. Implications for improving ADHD symptoms and overall functioning for this undertreated population are discussed.

    Attacks executed on Spanning Tree Protocol (STP) expose the weakness of link layer protocols and put the higher layers in jeopardy. Although the problems have been studied for many years and various solutions have been proposed, many security issues remain. To enhance the security and credibility of layer-2 network, we propose a trust-based spanning tree protocol aiming at achieving a higher credibility of LAN switch with a simple and lightweight authentication mechanism. If correctly implemented in each trusted switch, the authentication of trust-based STP can guarantee the credibility of topology information that is announced to other switch in the LAN. To verify the enforcement of the trusted protocol, we present a new trust evaluation method of the STP using a specification-based state model. We implement a prototype of trust-based STP to investigate its practicality. Experiment shows that the trusted protocol can achieve security goals and effectively avoid STP attacks with a lower computation overhead and good convergence performance.

    Lymphoma is one of the most frequent cancers in adolescent and young adults. Hodgkin Lymphoma is curable in more than 90% of cases. Recent pediatric and adults protocols aimed to decrease long term toxicities (mostly gonadic and cardiovascular) and secondary malignancies, reducing the use of alkylating agents and limiting radiation fields. Risk-adapted strategies, using positron emission tomography staging, are about to become a standard, both in adult and pediatric protocols. These approaches allow obtaining excellent results in adolescents with Hodgkin lymphoma. On the other hand, treatment of adolescents with diffuse large B-cell lymphoma raises some questions. Even through children have good outcomes when treated with risk-adapted strategies, adolescents who are between 15 and 18 years old seem to experience poorer survivals, whereas patients older than 18 years old have globally the same outcome than older adults. This category of patient needs a particular care, based on a tight coordination between adults and pediatric oncologists. Primary mediastinal lymphomas, a subtype of BLDCL frequent in young adult population, exhibits poorer outcomes in children or young adolescent population than in older ones. Taking together, B-cell lymphoma benefited from recent advances in immunotherapy (in particular with the extended utilization of rituximab) and metabolic response-adapted strategies. In conclusion, adolescent and young adult's lymphomas are very curable diseases but require a personalized management in onco-hematological units. Copyright © 2016 Société Française du Cancer.

    HIV-infected adolescents have disproportionately low rates of care retention and viral suppression. Approximately half disengage from care while transitioning to adult clinics, in part due to fragmented care systems and lack of streamlined protocols. We conducted 58 qualitative interviews with social service and health care providers across 14 Adolescent Trials Network clinics (n = 28) and 20 adult clinics that receive transitioning adolescents (n = 30) from August 2015-June 2016. We used the constant comparative approach to examine processes, barriers, and facilitators of adult care transition. Transition barriers coalesced around three levels. Structural: insurance eligibility, transportation, and HIV-related stigma; Clinical: inter-clinic communication, differences in care cultures, and resource/personnel limitations; and Individual: adolescents' transition readiness and developmental capacity. Staff-initiated solutions (e.g., grant-funded transportation) were often unsustainable and applied individual-level solutions to structural-level barriers. Comprehensive initiatives, which develop collaborative policies and protocols that support providers' ability to match the solution and barrier level (i.e., structural-to-structural), are sorely needed. These initiatives should also support local systematic planning to facilitate inter-clinic structures and communication. Such approaches will help HIV-infected adolescents transition to adult care and improve long-term health outcomes.

    Full Text Available Background: Youth between the ages of 15 years to 24 years account for almost half of new HIV infections in South Africa. Objectives: To describe the study details of the Botsha Bophelo Adolescent Health Study (BBAHS which was an investigation of HIV risk among adolescents living in Soweto, South Africa. Methods: Eligibility criteria for the BBAHS included being 14 years – 19 years old and living in one of the 41 identified formal and informal areas in the township of Soweto. A cross-sectional survey was developed between investigators and an adolescent community advisory board consisting of previously validated scales and original questions including demographics, sexual and reproductive health, health service utilisation and psychosocial behaviours. Results: Between 2010 and 2012, interviewers administered surveys among 830 adolescents (57% females, whose median age was 17 years (Q1, Q3: 16, 18, and found that 43% of participants identified their ethnicity as Zulu, 52% reported high food insecurity, 37% reported at least one parent had died, 15% reported living in a shack and 83% identified as heterosexual. Over half of the participants (55% reported ever having sex (49% of females and 64% of males, 11% of whom initiated sex at < 15 years of age (3% females and 21% males. Almost half (47% reported ever testing for HIV, 3% (n = 12 of whom self-reported being HIV-positive and 33% (n = 4 were on antiretroviral therapy. Conclusion: Our study highlights important individual, relational and structural level determinants of HIV risk for adolescent men and women growing up within HIV hyperendemic settings.

    This study examined functioning of the Hypothalamic Pituitary Adrenal (HPA) axis, a neurobiological stress system centrally implicated in depression, as a predictor of treatment response to Interpersonal Psychotherapy for Depressed Adolescents (IPT-A; Mufson et al., 2004. Interpersonal psychotherapy for depressed adolescents. (second ed.). New York, Guilford Press). The sample consisted of fifteen depressed adolescents (age 12-17; mean age=15.2; 86.7% female) experiencing high levels of conflict with their parents who were recruited to participate in a pilot study of individual IPT-A and IPT-A delivered with greater and more structured involvement of parents. Adolescents came primarily from low-income Latino (93.3%) families. Prior to treatment, adolescents participated in a 15 min conflict negotiation task with their parents in which salivary cortisol was collected prior to and 10, 20, and 30 min post-conflict. Adolescents' depression symptoms were assessed pre-treatment and post-treatment (week 16) using the Children's Depression Rating Scale (CDRS-R). Higher levels of cortisol 30 min after the conflict task were associated with greater improvement in depression symptoms with IPT-A, controlling for baseline levels of depression. The study has a small sample size. This is the first study to examine HPA functioning as a predictor of depressed adolescents' response to a psychotherapeutic intervention. If replicated with larger samples, these results have important implications for advancing the use of neurobiological markers to personalize psychotherapeutic interventions for depressed adolescents. © 2013 Elsevier B.V.

    School absenteeism is linked to a range of health concerns, health risk behaviors and school dropout. It is therefore important to evaluate the extent to which adolescents with absenteeism are in contact with health care and other services. The aim of the current study was to investigate service use of Norwegian adolescents with moderate and high absenteeism in comparison to students with lower rates of absence. The study employs data from a population-based study from 2012 targeting all pupils in upper secondary education in Hordaland County, Norway (the youth@hordaland-survey). A total of 8988 adolescents between the ages of 16 and 18 were included in the present study. Information on service use was based on adolescent self-report data collected in the youth@hordaland-survey. Absence data was collected using administrative data provided by the Hordaland County Council. High absence (defined as being absent 15% or more the past semester) was found among 10.1% of the adolescents. Compared to their peers with low absence (less than 3% absence the past semester), adolescents with high absence were more likely to be in contact with all the services studied, including mental health services (odds ratio (OR) 3.96), adolescent health clinics (OR 2.11) and their general practitioner (GP) (OR 1.94). Frequency of contact was higher among adolescents with moderate and high absence and there seems to be a gradient of service use corresponding to the level of absence. Still, 40% of the adolescents with high absence had not been in contact with any services. Adolescents with high absence had increased use of services, although a group of youth at risk seems to be without such contact. This finding suggests a potential to address school absenteeism through systematic collaboration between schools and health personnel.

    Adolescents and young adults with cancer face significant challenges during the course of their medical treatment and recovery from illness. Many adolescents and young adults struggle with long-term complications in the physical, psychosocial, economic, and academic domains. Mobile health (mHealth) interventions provide an innovative platform for delivering supportive care, particularly through the utilization of apps on smartphones and tablets. To create a successful mHealth intervention for adolescents and young adults, youth input and feedback is essential. The process of cocreation, in which the target app user has a direct role in dictating design and function, was utilized to create the prototype smartphone app for adolescents and young adults with cancer, "Kræftværket." The objective of this paper is to describe the protocol for the evaluation of the Kræftværket app, a prototype app designed via cocreation, to support and improve health-related quality of life for adolescents and young adults with cancer. The Kræftværket app has three primary features, (1) a symptom and activity diary, (2) a supportive communication network between app users, and (3) a "one-stop shop" information bank with practical information as well as links to patient organizations and other resources. The app will be evaluated in two phases, a pilot test and an implementation test. In the pilot test, the app will be launched to a test group of 20 adolescents and young adults aged 15 to 29 years, selected for equal representation amongst age group and treatment status. Patients will be allowed to utilize the app over the course of six weeks and will complete a baseline and follow-up European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) health-related quality of life inventory. In addition, participant focus group interviews will be conducted according to a semistructured interview guide. Resulting data will be analyzed

  5. Mind-Body Practices and the Adolescent Brain: Clinical Neuroimaging Studies.

    Sharma, Anup; Newberg, Andrew B

    Mind-Body practices constitute a large and diverse group of practices that can substantially affect neurophysiology in both healthy individuals and those with various psychiatric disorders. In spite of the growing literature on the clinical and physiological effects of mind-body practices, very little is known about their impact on central nervous system (CNS) structure and function in adolescents with psychiatric disorders. This overview highlights findings in a select group of mind-body practices including yoga postures, yoga breathing techniques and meditation practices. Mind-body practices offer novel therapeutic approaches for adolescents with psychiatric disorders. Findings from these studies provide insights into the design and implementation of neuroimaging studies for adolescents with psychiatric disorders. Clinical neuroimaging studies will be critical in understanding how different practices affect disease pathogenesis and symptomatology in adolescents. Neuroimaging of mind-body practices on adolescents with psychiatric disorders will certainly be an open and exciting area of investigation.

    Full Text Available Abstract Background Adequate levels of physical activity are part of a healthy lifestyle and in this way linked to better health outcomes. For children and adolescents, the physical activity guideline recommends at least 60 minutes of moderate-to-vigorous physical activity every day. However, many adolescents are not physically active enough and they spend a lot of their time on sedentary activities (such as video games. A new generation of video games that require body movements to play them, so-called "active games", could serve to increase physical activity in adolescents. The activity level while playing these games is comparable to light-to-moderate intensity physical activity. The current study aims to increase our understanding of 1 the demographic characteristics of adolescents who play active games regularly (≥ 1 hour per week and non-regularly ( Methods A cross-sectional survey was conducted in a Dutch internet panel, questioning adolescents in conjunction with one of their parents. A random sample of 320 households (with stratification on gender of the parent and the adolescent, the age of the adolescent and the region of the household was selected that owned a console or application for active video games and that had a child aged 12 through 16 years. 201 child–parent couples (63% response completed an internet survey with questions about demographics, physical activity and sedentary behaviour, and gaming behaviour. The questionnaire also contained questions designed to assess whether and how active gaming replaces other activities. Besides descriptive analyses, independent t-test, Pearson’s chi-square and Mann–Whitney test (when data were not normally distributed were used for comparisons between regular and non-regular active gamers. Results Eleven percent of the adolescents with an active game in their household never used the game. There were no significant differences in gender, education level (of adolescent and

    The aim of this study was to explore dental fear in a multicultural population of child and adolescent dental patients, with background, gender, age, and socioeconomic status taken into account. A specific aim was to investigate whether the level of DF differed between patients with a non- Swedish background and patients with a Swedish background. In conjunction with a routine visit to the dental clinic, 301 patients (8-19 years old) assessed their dental fear on the Children's Fear Survey Schedule - Dental Subscale, using self-ratings. Following an interview protocol, patients' and their parents' country of birth, and parents' education and occupation/employment were registered. An interpreter was present when needed. Self-rated dental fear was almost equal among patients coming from a non-Swedish background and patients with a Swedish background. Girls scored higher than boys and younger children scored slightly higher compared to older children, but the pattern of dental fear variation was inconsistent. Socioeconomic status differed between the groups with a non-Swedish vs. a Swedish background, but no impact on dental fear was revealed. When children and adolescents with a non-Swedish vs. a Swedish background were modelled separately, female gender and younger age had an impact on dental fear only in the group with a Swedish background. No differences in dental fear were found between children and adolescents from non-Swedish vs. Swedish backgrounds. Dental fear variations according to gender and age were more pronounced in the group with a Swedish background compared to the group with a non-Swedish background. No impact of socioeconomic status could be revealed.

    Studies have shown that adolescents with a history of both suicide attempts and non-suicidal self-harm report more mental health problems and other psychosocial problems than adolescents who report only one or none of these types of self-harm. The current study aimed to examine the use of child and adolescent psychiatric services by adolescents with both suicide attempts and non-suicidal self-harm, compared to other adolescents, and to assess the psychosocial variables that characterize adolescents with both suicide attempts and non-suicidal self-harm who report contact. Data on lifetime self-harm, contact with child and adolescent psychiatric services, and various psychosocial risk factors were collected in a cross-sectional sample (response rate = 92.7%) of 11,440 adolescents aged 14-17 years who participated in a school survey in Oslo, Norway. Adolescents who reported any self-harm were more likely than other adolescents to have used child and adolescent psychiatric services, with a particularly elevated likelihood among those with both suicide attempts and non-suicidal self-harm (OR = 9.3). This finding remained significant even when controlling for psychosocial variables. In adolescents with both suicide attempts and non-suicidal self-harm, symptoms of depression, eating problems, and the use of illicit drugs were associated with a higher likelihood of contact with child and adolescent psychiatric services, whereas a non-Western immigrant background was associated with a lower likelihood. In this study, adolescents who reported self-harm were significantly more likely than other adolescents to have used child and adolescent psychiatric services, and adolescents who reported a history of both suicide attempts and non-suicidal self-harm were more likely to have used such services, even after controlling for other psychosocial risk factors. In this high-risk subsample, various psychosocial problems increased the probability of contact with child and

    Low IQ is associated with high BMI in childhood. There are inconsistent findings on the association between low SES and high BMI. Youth with low IQ have been reported to have poorer health behaviors, such as poor nutrition and less physical activity. Low IQ is significantly associated with obesity for both male and female adolescents, though more strongly for female adolescents. Physical activity has a mediating effect on the association between low IQ and obesity among both male and female adolescents, though more strongly for male adolescents. The association between low IQ and obesity is strongest among adolescents from high SES backgrounds. Previous studies have shown an association between low intelligence quotient (IQ), high body mass index and low socioeconomic status (SES). This study examined the cross-sectional association between IQ and obesity, exploring the roles of gender, SES and physical activity in this association. Subjects were 235,663 male and 169,259 female adolescents assessed by the Israeli military draft board. Low IQ was significantly associated with increased odds of obesity among male (odds ratio [OR] = 1.44, 95% confidence interval [CI] = 1.36-1.52) and female adolescents (OR = 1.61, 95% CI = 1.51-1.73); this association was significantly stronger among female adolescents. Sobel tests indicated that physical activity had a significant mediating effect on this association for male and female adolescents, although more strongly for male adolescents. Dividing the sample according to SES, the association between low IQ and obesity was strongest in the high SES group (male adolescents: OR = 1.26, 95% CI = 1.10-1.43, female adolescents: OR = 1.61, 95% CI = 1.38-1.89), even when controlling for physical activity. The findings suggest that low IQ is associated with increased odds of obesity, particularly in female adolescents and in adolescents with high SES. Physical activity has a mediating effect on this

    To evaluate the influence of an app-based approach in a protocol for domestic oral hygiene maintenance in a group of adolescent patients wearing fixed multibracket appliances. Eighty adolescent patients scheduled to start an orthodontic multibracket treatment were randomly divided into two groups of 40. Plaque index (PI), gingival index (GI), white spots (WS), and caries presence were recorded in all patients, and they were instructed regarding domestic oral hygiene maintenance on the day of braces application (t0) and every 3 months (t1, t2, t3, t4) during the first year of treatment. Study group (SG) patients were enrolled in a WhatsApp chat room-based competition and instructed to share monthly with the other participants two self-photographs (selfies) showing their oral hygiene status. SG patient participation in the chat room was regular and active throughout the observation period. At t2, t3, and t4, SG patients had significantly lower values of both PI and GI and a lower incidence of new WS and caries, compared with the control group. Integration of new "social" technologies in a standard oral hygiene motivation protocol is effective in improving compliance of adolescent patients and in improving their oral health status during orthodontic multibracket treatment.

    Full Text Available Alcohol, psychoactive substance, harmful to health, has been widely accepted and consumed by society in a premature manner. The Brazilian contemporaneous reality has demonstrated a high number of adolescents who consume alcohol on regularly basis, and nowadays, its damages start to be evident, hence the importance of contextualizing this issue in relation to adolescents. This study aims to determine the profile of alcohol consumption in adolescent students of a public high school in a city of the inland of Bahia, Brazil. It is a descriptive study with quantitative approach, conducted with 98 male and female students, and a structured questionnaire used to collect data, which was analyzed with aid of descriptive statistics. The survey was approved by the Ethics in Research Committee Involving Human Beings, of the State Perfil do consumo de bebidas alcoólicas por adolescentes University of Southwest Bahia – campus of Jequié-Bahia, Brazil under Protocol 179/2009. It was perceived that most of the teenagers had already consumed alcohol prematurely, with minimaldifference between male and female gender. Several of these adolescents continue consuming too much and too often, influenced by friends, family and media. It can be concluded that it is imperative to insert educational methodological proposals at schools which should instruct about premature and indiscriminate alcohol consumption, addressing principally risk factors and possible biopsychosocial complications

    Full Text Available Recent developments in the area of micro-sensor devices have accelerated advances in the sensor networks field leading to many new protocols specifically designed for wireless sensor networks (WSNs. Wireless sensor networks with hundreds to thousands of sensor nodes can gather information from an unattended location and transmit the gathered data to a particular user, depending on the application. These sensor nodes have some constraints due to their limited energy, storage capacity and computing power. Data are routed from one node to other using different routing protocols. There are a number of routing protocols for wireless sensor networks. In this review article, we discuss the architecture of wireless sensor networks. Further, we categorize the routing protocols according to some key factors and summarize their mode of operation. Finally, we provide a comparative study on these various protocols.

    Growing interest in emotion regulation is reflected in the studies of cognitive and social development. However, the extant studies mainly highlight how emotion regulation develops based on a western value system. This study utilised a longitudinal design to examine the development of emotion regulation and explored the contributions of different regulatory strategies to emotion experience regarding the early adolescent development period in a Chinese population. A total of 303 Chinese adolescents (age range = 10-14 years) were followed up in a three-phase longitudinal study for 3 years. In each phase of the study, participants completed Adolescents Emotion Regulation Questionnaire and Daily Emotion Scale. Results of hierarchical linear regressions revealed that Chinese adolescents reported more down-regulation. Down-regulation is more effective than up-regulation in enhancing desirable emotion experience and reducing undesirable emotion experience during adolescents' development. Also, the adaptive functions of emotional regulatory strategies in Chinese background were discussed. © 2014 International Union of Psychological Science.

    To compare parent and adolescent reports in exploring adolescent sleep problems and to identify the factors associated with adolescent sleep problem disclosures. Parent (n = 5185) and adolescent reports (n = 5171, age=13.9 ± 0.3 years), from a birth cohort were used to explore adolescent sleep problems. Kappa coefficients were used to assess the agreement, whereas, conditional agreement and disagreement ratios were used to identify the optimal informant. Logistic regression analysis was used to determine the factors affecting adolescent sleep problem disclosure. Parental reports identified only about one-third of the sleep problems reported by adolescents. Whereas adolescent reports identified up to two-thirds of the sleep problems reported by parents. Combined reports of parents and adolescent did not show any considerable difference from the adolescent report. Adolescent and parent health, maternal depression, and family communication were significantly associated with adolescents sleep problem disclosures. Adolescent reports could be used as the preferred source to explore adolescent sleep problems. Parental reports should be used when parents as observers are more reliable reporters, or where adolescents are cognitively unable to report sleep problems. Additionally, the impact of poor health, maternal depression and family communication on sleep problems disclosure should be considered for adolescent sleep problem diagnosis. ©2016 Foundation Acta Paediatrica.

    Full Text Available Abstract Background Physical inactivity is increasing among adolescents in the U.S., especially among girls. Despite growing evidence that parents are an important influence on adolescent health, few longitudinal studies have explored the causal relationship between parental influence and physical activity. This study examines how the relationships between parental influences and adolescent physical activity differ by gender and tests whether these relationships are mediated by adolescents' self-esteem and depression. Methods Data are from the National Longitudinal Study of Adolescent Health. The sample includes 13,246 youth, grades 7 to 12, interviewed in 1995 and again 1 year later. Logit models were used to evaluate parental influences on achieving five or more bouts of moderate to vigorous physical activity per week [MVPA] and whether the relationship between parental influence and MVPA was mediated by adolescents' level of self-esteem and depression. Results Family cohesion, parent-child communication and parental engagement positively predicted MVPA for both genders one year later (odds ratios and 95% confidence intervals for females, 1.09 [1.05–1.12], 1.13 [1.07–1.19], 1.25 [1.17–1.33] and males, 1.08 [1.04–1.11], 1.14 [1.07–1.23], 1.23 [1.14–1.33], respectively; however, parental monitoring did not (odds ratio and confidence intervals for females and males, 1.02 [.97–1.07]. For both females and males, self-esteem mediated the relationship between parental influence and physical activity. Depressive symptoms were only a mediator among males. Females reported higher levels of parent-child communication and lower family cohesion compared with males. There were no gender differences in levels of parental monitoring and engagement. Females had significantly lower levels of self-esteem and higher levels of depressive symptoms than males. Conclusion Strategies to promote physical activity among adolescents should focus on

    Eczema is a common chronic or chronically relapsing, inflammatory skin disease that exerts a substantial negative impact on quality of life (QoL). The Harmonising Outcome Measures for Eczema (HOME) initiative has used a consensus-based process which identified QoL as one of the four core outcome domains to be assessed in all eczema clinical trials. A number of measurement instruments exist to measure QoL in infants, children, and adolescents with eczema, and there is a great variability in both content and quality of the instruments used. Therefore, the objective of the proposed research is to comprehensively and systematically assess the measurement properties of the existing measurement instruments that were developed and/or validated for the measurement of patient-reported QoL in infants, children, and adolescents with eczema. This study is a systematic review of the measurement properties of patient-reported measures of QoL developed and/or validated for infants, children, and adolescents with eczema. A systematic literature search will be carried out in MEDLINE via PubMed and EMBASE using a selection of relevant search terms. Eligible studies will be primary empirical studies evaluating, describing, or comparing measurement properties of QoL instruments for infants, children, and adolescents with eczema. Two reviewers will independently perform eligibility assessment and data abstraction. Evidence tables will be used to record study characteristics, instrument characteristics, measurement properties, and interpretability. The adequacy of the measurement properties will be assessed using predefined criteria. The COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist will be used to evaluate the methodological quality of included studies. A best evidence synthesis will be undertaken if more than one study has examined a particular measurement property. The proposed systematic review will yield a comprehensive assessment

    Full Text Available Reward/behavioral approach system hypersensitivity is implicated in bipolar disorders (BD and in normative development during adolescence. Pediatric onset of BD is associated with a more severe illness course. However, little is known about neural processing of rewards in adolescents with BD or developmental (i.e., age associations with activation of these neural systems. The present study aims to address this knowledge gap. The present sample included 21 adolescents with BD and 26 healthy adolescents, ages 13 to 19. Participants completed a functional magnetic resonance imaging (fMRI protocol using the Monetary Incentive Delay (MID task. Behavioral performance was similar between groups. Group differences in BOLD activation during target anticipation and feedback anticipation periods of the task were examined using whole-brain analyses, as were group differences in age effects. During both target anticipation and feedback anticipation, adolescents with BD, compared to adolescents without psychopathology, exhibited decreased engagement of frontal regions involved in cognitive control (i.e., dorsolateral prefrontal cortex. Healthy adolescents exhibited age-related decreases, while adolescents with BD exhibited age-related increases, in activity of other cognitive control frontal areas (i.e., right inferior frontal gyrus, suggesting altered development in the BD group. Longitudinal research is needed to examine potentially abnormal development of cognitive control during reward pursuit in adolescent BD and whether early therapeutic interventions can prevent these potential deviations from normative development.

    Objectives: To determine the existing knowledge, attitude and behavior about reproductive and sexual health in adolescents of Karachi and seek their opinion about reproductive health education. Study type, settings and duration: A cross sectional study was conducted on adolescents (17-19 years) of both gender studying in colleges of Karachi during 2010. Subject sand Methods: Using stratified sampling procedure, a cross sectional study was carried out. After informed consent and ensuring confidentiality an anonymous quantitative questionnaire was completed to ascertain the knowledge of adolescents on reproductive health. Results: A total of 912 adolescents (470 males and 442 females) of 12 public and private sector colleges of Karachi participated in the study. Acquaintance to reproductive health was present in 75% males and 71% females and most participants confirmed discussing reproductive health issues with friends. About 81% males and 91 % females affirmed for a need for enhanced reproductive health education and awareness while over 50% of the respondents were of the opinion that the right age for reproductive health education was 16 to 18 years. Confining sexual activity to one partner and avoiding exposure to blood and needles for the prevention of AIDS was known to 38% males and 44% females but the prevention of sexually transmitted infections using condoms, was known to only 1/3 rd of the respondents. Although 70% of the respondents of both genders knew that pregnancy can be avoided but only 20% knew about contraceptives. Conclusions: Most adolescents' knew about the reproductive cycle but were not well aware of how to avoid exposures to sexually transmitted infections and pregnancies. Policy message: Reproductive health education is insufficient in adolescents should be gender specific and socio culturally sensitive. (author)

    To describe sedentary behaviors in adolescents and to examine the influence of media availability on TV viewing. The study assessed 3278 adolescents (1537 males and 1741 females, 12.5-17.5 years) involved in the HELENA study (2007). Adolescents reported hours of TV viewing, computer games, console, internet for study and non-study reasons, and study, as well as availability of TVs, computers and consoles. Time spent in sedentary behaviors was higher during weekends (all p or = 15 years at weekends), playing computer games and console games while females spent more time studying and surfing for non-study reasons. During weekdays, one third of adolescents exceeded the screen time guidelines (>2h/day) based solely on TV viewing, whereas around 60% exceeded it at weekends. Having a TV or a console in the bedroom was associated with higher TV viewing (OR=2.66; 95% CI 2.23-3.18; and OR=1.92; 95% CI 1.61-2.28, respectively) whereas the presence of computer reduced it (OR=0.57; 95% CI 0.48-0.68). Adolescents living in Europe are not meeting media recommendations, especially during weekend. The absence of a TV in the adolescents' bedroom might reduce TV viewing. Further studies are needed to confirm or contrast our findings. Copyright 2010 Elsevier Inc. All rights reserved.

    Health maintenance and promotion are the fundamental prerequisites to community development. The best time for establishing healthy lifestyle habits is during adolescence. Due to importance of health promotion behaviors in adolescents, this study was conducted to investigate health-promoting behaviors and its associated factors among high school students in Rasht, Iran. A cross-sectional descriptive study was conducted on 424 students during the first semester of the year 2012. We employed the multistage sampling design to recruit from private and public high schools in Rasht, Iran. The data collection instrument was a self-report questionnaire consisting of two parts. The first part of instrument was consisted of demographic questionnaire and the second part was adolescent health promotion scale (AHPS) questionnaire. AHPS questionnaire was consisted of six dimensions (nutrition, social support, health responsibility, life appreciation, physical activity, and stress management) to measure health promoting lifestyles. Statistical analysis was performed by SPSS 16 software employing ANOVA (analysis of variance) test, t-test, Mann-Whitney, and the Kruskal-Wallis. The score of total Adolescent Health Promotion Scale were 3.58 ± 0.52 (possible range was 1-5). The highest score was in life appreciation dimension (3.99 ± 0.068) and the lowest score was in health responsibility dimension. Moreover, Significant associations were found between the adolescent health promotion Scale with age (P school grade (P health instructors, schoolteachers, and families must pay more attention to these students. Moreover, as most of lifelong healthy and unhealthy lifestyle habits are established during adolescence, developing effective health promotion and disease prevention strategies for adolescents seems crucial.

    Voluntary consent/assent with adolescents invited to participate in research raises challenging problems. No studies to date have attempted to manipulate autonomy in relation to assent/consent processes. This study evaluated the effects of an autonomy-enhanced individualized assent/consent procedure embedded within a randomized pediatric asthma clinical trial. Families were randomly assigned to remain together or separated during a consent/assent process; the latter we characterize as an autonomy-enhanced assent/consent procedure. We hypothesized that separating adolescents from their parents would improve adolescent assent by increasing knowledge and appreciation of the clinical trial and willingness to participate. Sixty-four adolescent-parent dyads completed procedures. The together versus separate randomization made no difference in adolescent or parent willingness to participate. However, significant differences were found in both parent and adolescent knowledge of the asthma clinical trial based on the assent/consent procedure and adolescent age. The separate assent/consent procedure improved knowledge of study risks and benefits for older adolescents and their parents but not for the younger youth or their parents. Regardless of the assent/consent process, younger adolescents had lower comprehension of information associated with the study medication and research risks and benefits, but not study procedures or their research rights and privileges. The use of an autonomy-enhanced assent/consent procedure for adolescents may improve their and their parent's informed assent/consent without impacting research participation decisions. Traditional assent/consent procedures may result in a "diffusion of responsibility" effect between parents and older adolescents, specifically in attending to key information associated with study risks and benefits.

    To compare depression identification and management perceptions and practices between professions and disciplines in primary care and examine factors that increase the likelihood of administering a standardized depression screening instrument, asking about patients' depressive symptoms, and using best practice when managing depressed adolescents. Data came from an online survey of clinicians in Minnesota (20% response rate). Analyses involved bivariate tests and linear regressions. The analytic sample comprised 260 family medicine physicians, 127 pediatricians, 96 family nurse practitioners, and 54 pediatric nurse practitioners. Overall, few differences emerged between physicians and nurse practitioners or family and pediatric clinicians regarding addressing depression among adolescents. Two factors associated with administering a standardized instrument included having clear protocols for follow-up after depression screening and feeling better prepared to address depression among adolescents. Enhancing clinicians' competence to address depression and developing postscreening protocols could help providers implement universal screening in primary care.

    Treatment and rehabilitation interventions in juvenile justice institutions aim to prevent criminal reoffending by adolescents and to enhance their prospects of successful social reintegration. There is evidence that these goals are best achieved when the institution adopts a family-centered approach, involving the parents of the adolescents. The Academic Workplace Forensic Care for Youth has developed two programs for family-centered care for youth detained in groups for short-term and long-term stay, respectively. The overall aim of our study is to evaluate the family-centered care program in the first two years after the first steps of its implementation in short-term stay groups of two juvenile justice institutions in the Netherlands. The current paper discusses our study design. Based on a quantitative pilot study, we opted for a study with an explanatory sequential mixed methods design. This pilot is considered the first stage of our study. The second stage of our study includes concurrent quantitative and qualitative approaches. The quantitative part of our study is a pre-post quasi-experimental comparison of family-centered care with usual care in short-term stay groups. The qualitative part of our study involves in-depth interviews with adolescents, parents, and group workers to elaborate on the preceding quantitative pilot study and to help interpret the outcomes of the quasi-experimental quantitative part of the study. We believe that our study will result in the following findings. In the quantitative comparison of usual care with family-centered care, we assume that in the latter group, parents will be more involved with their child and with the institution, and that parents and adolescents will be more motivated to take part in therapy. In addition, we expect family-centered care to improve family interactions, to decrease parenting stress, and to reduce problem behavior among the adolescents. Finally, we assume that adolescents, parents, and the

    Most studies about informant agreements on adolescents' emotional and behavioral problems have been conducted in Western countries, but this subject has not been well researched in China. The aim of this study was to evaluate the pattern of parent-adolescent agreement on adolescents' problems and its associated factors among school-age adolescents in China. This cross-sectional study was conducted in November and December of 2010. A questionnaire including the Child Behavior Checklist (CBCL), the Youth Self-Report (YSR), the Family Environment Scale (FES) and the characteristics of the child (age and gender), parents (parent-adolescent relationship and parental expectations) and family (family structure, negative life events) was distributed to our study population. A total of 2,199 Chinese adolescents (aged 11-18) from 15 public schools in Liaoning Province, who completed the questionnaire, became our final participants. Pearson's correlation coefficient was used to assess parent-adolescent agreement, and linear regression analysis was used to explore the associated factors of parent-adolescent discrepancies on emotional and behavioral problems. The parent-adolescent agreement on emotional and behavioral problems was high (mean r = 0.6). The scores of YSR were higher than those of CBCL. Factors that increased informant discrepancies on emotional and behavioral problems were boys, older age, the experience of negative life events, low levels of cohesion and organization, and high levels of conflict in the family. A high level of parent-adolescent agreement on emotional and behavioral problems was found. Adolescents reported more problems than their parents did. Family environment is an important factor to be considered when interpreting informant discrepancies on the mental health of Chinese adolescents.

    Full Text Available Many clinical studies are ultimately not fully published in peer-reviewed journals. Underreporting of clinical research is wasteful and can result in biased estimates of treatment effect or harm, leading to recommendations that are inappropriate or even dangerous.We assembled a cohort of clinical studies approved 2000-2002 by the Research Ethics Committee of the University of Freiburg, Germany. Published full articles were searched in electronic databases and investigators contacted. Data on study characteristics were extracted from protocols and corresponding publications. We characterized the cohort, quantified its publication outcome and compared protocols and publications for selected aspects.Of 917 approved studies, 807 were started and 110 were not, either locally or as a whole. Of the started studies, 576 (71% were completed according to protocol, 128 (16% discontinued and 42 (5% are still ongoing; for 61 (8% there was no information about their course. We identified 782 full publications corresponding to 419 of the 807 initiated studies; the publication proportion was 52% (95% CI: 0.48-0.55. Study design was not significantly associated with subsequent publication. Multicentre status, international collaboration, large sample size and commercial or non-commercial funding were positively associated with subsequent publication. Commercial funding was mentioned in 203 (48% protocols and in 205 (49% of the publications. In most published studies (339; 81% this information corresponded between protocol and publication.

    Full Text Available Adolescents' behavior is often a matter of concern, given their increased likelihood of enacting antisocial behaviors, which cause disruptions in the social order and are potentially harmful for the adolescents themselves and for the people around them. In this six-wave longitudinal study we sought to examine the interplay among maternal empathy, multiple indicators of mother-adolescent relationship quality (i.e., balanced relatedness, conflict, and support, and adolescent antisocial behaviors rated both by adolescents and their mothers. Participants for the current study were 497 Dutch adolescents (56.9% males followed from age 13 to 18, and their mothers. A series of cross-lagged panel models revealed reciprocal associations between maternal empathy and mother-adolescent relationship quality and between mother-adolescent relationship quality and adolescent antisocial behaviors. Interestingly, we also found some indirect effects of adolescent antisocial behaviors on maternal empathy mediated by mother-adolescent relationship quality. Overall, this study further highlights a process of reciprocal influences within mother-adolescent dyads.

    Full Text Available Self-management of diabetes is challenging, especially for adolescents who face multiple changes, including closer peer relationships. Few studies have explored how friends can provide constructive support in this effort. The present research investigated, in two qualitative studies, the perceptions of adolescents with diabetes and their friends with respect to the positive social support that friends can offer. In study 1, 28 adolescents aged 12–15 with type 1 diabetes participated in online focus groups. In study 2, 11 of these adolescents were interviewed in person together with their best friends. The data were analysed by means of content analysis. In study 1, the adolescents with diabetes identified various supportive behaviours of friends, particularly concerning emotional support: treating them normally, showing interest, having fun, providing a distraction, and taking their diabetes into account. They differed in their attitude towards support, and this influenced which behaviours they perceived as supportive. Study 2 showed that the adolescents with diabetes and their friends often had similar opinions on the desired degree of support. Fear of stigmatization and sense of autonomy withheld some adolescents with diabetes from soliciting more support. These insights can be useful in patient education aiming to promote social support.

    The mental health of children and adolescents is a key area of health concern internationally. Previous empirical studies suggest that resilience may act as a protective mechanism towards the development of mental health problems. Resilience refers to the ability to employ a collection of protective factors to return to or maintain positive mental health following disadvantage or adversity. Schools represent a potential setting within which protective factors of all children and adolescents may be fostered through resilience-focussed interventions. Despite this potential, limited research has investigated the effectiveness of universal school-based resilience-focussed interventions on mental health outcomes in children and adolescents. The objective of the present review is to assess the effects of universal school-based resilience-focussed interventions, relative to a comparison group, on mental health outcomes in children and adolescents. Eligible studies will be randomised (including cluster-randomised) controlled trials of universal interventions explicitly described as resilience-focussed or comprising strategies to strengthen a minimum of three internal protective factors, targeting children aged 5 to 18 years, implemented within schools, and reporting a mental health outcome. Screening for studies will be conducted across six electronic databases: MEDLINE, PsycINFO, Educational Resources Information Center (ERIC), Excerpta Medica database (EMBASE), Cumulative Index to Nursing and Allied Health Literature (CINAHL), and the Cochrane Central Register of Controlled Trials (CENTRAL). Two reviewers will retrieve eligible articles, assess risk of bias, and extract data. Where studies are sufficiently homogenous and reported outcomes are amenable for pooled synthesis, meta-analysis will be performed. Narrative description will be used to synthesise trial outcome data where data cannot be combined or heterogeneity exists. This review will aid in building an evidence

A retrospective study of patients' records of the Glomerulopathy Section, UNIFESP (Brazil), was performed Among 72 adolescents (12-18 years) with GP, 15.6 +/- 1.5 years, 58.3% females, the most frequent clinical manifestation was nephrotic syndrome (NS, 71%) and focal segmental glomerulosclerosis (FSGS) was the main histological pattern (24%), followed by minimal change disease (MCD, 19.5%). After comparing the main causes of NS in adolescents with those of adults, we found no statistically significant differences in clinical presentation or outcome. Renal failure-free survival of 1 and 5 years for all GP corresponded to 87.9 and 73.6%, respectively (88.5 and 76.3% for NS). NS was the main manifestation; FSGS and MCD were the most common histological diagnoses. Our data suggest the GP and particularly the NS pattern in adolescents is similar to that of adults, pointing to the need for an adaptation in diagnostic and treatment protocols for this age group, a pattern which corresponds more closely to that of adults.

    To evaluate the prevalence of elevated glycated haemoglobin (HbA1c) levels in a population of adolescents participating in the Study of Cardiovascular Risk in Adolescents. This is a school-based cross-sectional study based on a complex sample of adolescents 12-17years old representative at the national and macro-regional levels and for each Brazilian state capital. Blood was collected in schools and then evaluated in a single laboratory. HbA1c levels were considered elevated if ⩾5.7% (39mmol/mol) and were analyzed according to sex, age, macro-region, type of school, skin color, and nutritional status. Data from 37,804 adolescents were analyzed. The mean level of HbA1c was 5.4% (95%CI 5.4-5.4) (36mmol/mol [95%CI 36-36]), and 20.5% (95%CI 19.1-22.0) of adolescents presented values ⩾5.7% (⩾39mmol/mol). Among males, 23.6% (95%CI 21.8-25.6) showed elevated HbA1c levels compared to 17.5% (95%CI 15.9-19.2) observed in females. The prevalence of elevated levels of HbA1c was higher in adolescents with black skin color (27.6%; 95%CI 23.2-32.4) vs. white skin color (16.9%; 95%CI 15.4-18.5), and higher in those who studied in public schools (21.6%; 95%CI 20.0-23.4) vs. private schools (16.7%; 95%CI 14.7-19.0). Among obese adolescents, 29.7% (95%CI 25.4-34.3) had elevated levels of HbA1c, compared to 19.3% (95%CI 18.0-20.7) in normal weight students and 19.7% (95%CI 17.1-22.6) in overweight adolescents. Obese male adolescents of lower socioeconomic status had a higher prevalence of elevated HbA1c levels. Our findings highlight the importance of focusing on this high risk group for interventions to prevent diabetes. Copyright © 2017 Elsevier B.V. All rights reserved.

    Adolescents’ behavior is often a matter of concern, given their increased likelihood of enacting antisocial behaviors, which cause disruptions in the social order and are potentially harmful for the adolescents themselves and for the people around them. In this six-wave longitudinal study we sought to examine the interplay among maternal empathy, multiple indicators of mother-adolescent relationship quality (i.e., balanced relatedness, conflict, and support), and adolescent antisocial behaviors rated both by adolescents and their mothers. Participants for the current study were 497 Dutch adolescents (56.9% males) followed from age 13 to 18, and their mothers. A series of cross-lagged panel models revealed reciprocal associations between maternal empathy and mother-adolescent relationship quality and between mother-adolescent relationship quality and adolescent antisocial behaviors. Interestingly, we also found some indirect effects of adolescent antisocial behaviors on maternal empathy mediated by mother-adolescent relationship quality. Overall, this study further highlights a process of reciprocal influences within mother-adolescent dyads. PMID:26990191

    Background There is limited data on objectively determined habitual physical activity (PA) in 16-year old South African adolescents. The purpose of this study was to objectively determine the habitual PA of adolescents from the North West Province of South Africa by race and gender. Methods Adolescents (137 girls, 89 boys) from the ongoing Physical Activity and Health Longitudinal Study (PAHL study), participated in the present study. Habitual PA was objectively recorded by means of the Actiheart® over a period of 7 days. Time spent in moderate-to-vigorous intensity physical activity (MVPA) was assessed. Results Average MVPA for the study sample was 50.9 ± 40.3 minutes/day. Girls were significantly more active than boys expending more time in MVPA (61.13 ± 52.2 minutes/day; p Physical activity varies by both gender and race in adolescents from the North West Province of South Africa. Objectively determined data from our study indicates that girls habitually spend more time in MVPA per day than boys, and that white adolescents habitually engage in more MVPA than black adolescents. Seeing as the average MVPA per day for the entire study sample falls below the recommended daily average of 60minutes/day, adolescents should be the foremost targets of interventions aimed at enhancing habitual PA.

    Full Text Available Context: Amidst the uncertainty in childhood blood pressure (BP thresholds, besides the ambiguity in levels and duration of BP elevation causing organ damage, hypertension is present in substantial number of asymptomatic children and adolescents with only a few studies disclosing the setup. With projection of deaths due to noncommunicable diseases in 2030 rising to 52 million, it is necessary to know about the knowledge of present adolescents about BP and its modifiable risk factors. Aims: (1 To assess the prevalence of elevated BP among adolescents and to ascertain the associated risk factors. (2 To assess adolescent's knowledge about BP and its modifiable factors. Settings and Design: A community-based cross-sectional study was conducted on school going adolescents of Lucknow, from September 2014 to August 2015. Subjects and Methods: BP, height, and weight were measured following standard protocols, Centers for Disease Control and Prevention charts for finding respective cut-off values and oral questionnaire for assessing lifestyle risk factors were used. Statistical Analysis: Chi-square, unpaired t-test, and logistic regression were used. Results: Of the 1041 participants, elevated BP (BP percentile ≥90 was prevalent in 24.2%. On regression, factors such as obesity (adjusted odds ratio [aOR] = 5.8, 95% confidence interval [CI] = 3.6–9.4, low fruit diet (aOR = 3.3, 95% CI = 2.1–5.4, and frequent junk food consumption (aOR = 1.9, 95% CI = 1.3–2.8 raised the odds of elevated BP while it was lowered by being physically active (aOR = 0.67, 95% CI = 0.46–0.97. Of 86.3% of children (n = 898 who were fathomed of BP, only less than third (33% and 21.9% acquainted of BP raising and lowering practices, respectively. Conclusions: Prevalence of high BP is colossal with only a few children knowing its amendable nature. Strenuous efforts targeting detrimental behaviors and imparting the sense of healthy lifestyle enhancing practices are vital to

    In The Netherlands, excessive alcohol use (e.g., binge drinking) is prevalent among adolescents. Alcohol use in general and binge drinking in particular comes with various immediate and long term health risks. Thus, reducing binge drinking among this target group is very important. This article describes a two-arm Cluster Randomized Controlled Trial (CRCT) of an intervention aimed at reducing binge drinking in this target group. The intervention is a Web-based, computer-tailored game in which adolescents receive personalized feedback on their drinking behavior aimed at changing motivational determinants related to this behavior. The development of the game is grounded in the I-Change Model. A CRTC is conducted to test the effectiveness of the game. Adolescents are recruited through schools, and schools are randomized into the experimental condition and the control condition. The experimental condition fills in a baseline questionnaire assessing demographic variables, motivational determinants of behavior (attitude, social influences, self-efficacy, intention) and alcohol use. They are also asked to invite their parents to take part in a short parental component that focusses on setting rules and communicating about alcohol. After completing the baseline questionnaire, the experimental condition continues playing the first of three game scenarios. The primary follow-up measurement takes place after four months and a second follow-up after eight months. The control condition only fills in the baseline, four and eight month follow-up measurement and then receives access to the game (i.e., a waiting list control condition). The effectiveness of the intervention to reduce binge drinking in the previous 30 days and alcohol use in the last week will be assessed. Furthermore, intention to drink and binge drink are assessed. Besides main effects, potential subgroup differences pertaining to gender, age, and educational background are explored. The study described in this

    Adolescence represents an important period for the development of executive functions, which are a set of important cognitive processes including attentional control. However, very little is known regarding the associations of nutrition with components of executive functions in adolescence. Thus, the aim of this study was to investigate associations of dietary patterns and macronutrient composition with attention capacity in European adolescents. This cross-sectional study included 384 (165 boys and 219 girls) adolescents, aged 12·5-17·5 years, from five European countries in the Healthy Lifestyle in Europe by Nutrition in Adolescence study. Attention capacity was examined using the d2 Test of Attention. Dietary intake was assessed through two non-consecutive 24 h recalls using a computer-based self-administered tool. Three dietary patterns (diet quality index, ideal diet score and Mediterranean diet score) and macronutrient/fibre intakes were calculated. Linear regression analysis was conducted adjusting for age, sex, BMI, maternal education, family affluence scale, study centre and energy intake (only for Mediterranean diet score). In these adjusted regression analyses, higher diet quality index for adolescents and ideal diet score were associated with a higher attention capacity (standardised β=0·16, P=0·002 and β=0·15, P=0·005, respectively). Conversely, Mediterranean diet score or macronutrient/fibre intake were not associated with attention capacity (P>0·05). Our results suggest that healthier dietary patterns, as indicated by higher diet quality index and ideal diet score, were associated with attention capacity in adolescence. Intervention studies investigating a causal relationship between diet quality and attention are warranted.

    To investigate the influence of parenting styles (overprotection, emotional warmth, and rejection) in early adolescence on regular alcohol use in late adolescence. We analyzed data from the first three waves (mean ages: 11.09, 13.56, and 16.27 years, respectively) of a population-based prospective cohort study of 2,230 adolescents, conducted between 2001 and 2007. Adolescents reported on parental overprotection, emotional warmth, and rejection (T1). Regular alcohol use was defined as six and seven glasses or more a week for girls and boys, respectively. We further assessed family socioeconomic status, parental divorce, parental alcohol use, educational level of the adolescent, and alcohol use at baseline. Parental overprotection had the strongest relationship to regular alcohol use: adolescents who perceived more parental overprotection were at increased risk of developing regular alcohol use, even after adjustment for several confounders. Rejection was not related to adolescents' alcohol use and, after adjustment for the other variables, neither was emotional warmth. Overprotective parenting is a determinant of future regular adolescent alcohol use and therefore health professionals should pay particular attention to those adolescents who have overprotective parents. The role of adolescent characteristics in the relationship between overprotection and alcohol use deserves further study. Copyright © 2012 S. Karger AG, Basel.

    Early adolescence is characterized by increases in parent-adolescent hostility, yet little is known about what predicts these changes. Utilizing a fairly large sample (N = 416, 51 % girls, 91 % European American), this study examined the conjoint and unique influences of adolescent social anxiety symptoms and parental intrusiveness on changes in parent-adolescent hostility across early adolescence. Higher mother and father intrusiveness were associated with increased mother- and father-adolescent hostility. An examination of reciprocal effects revealed that mother- and father-adolescent hostility predicted increased mother and father intrusiveness. Significant associations were not substantiated for adolescent social anxiety symptoms. These findings suggest that intrusive parenting has important implications for subsequent parent-adolescent interactions and that similar patterns may characterize some aspects of mother- and father-adolescent relationships.

    Full Text Available Due to the scale up of antiretroviral therapy, increasing numbers of HIV-infected children are living into adolescence. As these children grow and surpass the immediate threat of death, the issue of informing them of their HIV status arises. This study aimed to understand how perinatally-infected adolescents learn about their HIV-status as well as to examine their preferences for the disclosure process.In-depth interviews were conducted with 31 (14 male, 17 female perinatally-infected adolescents aged 16-20 at an HIV clinic in Harare, Zimbabwe, and focused on adolescents' experiences of disclosure. In addition, 15 (1 male, 14 female healthcare workers participated in two focus groups that were centred on healthcare workers' practices surrounding disclosure in the clinic. Purposive sampling was used to recruit participants. A coding frame was developed and major themes were extracted using grounded theory methods.Healthcare workers encouraged caregivers to initiate disclosure in the home environment. However, many adolescents preferred disclosure to take place in the presence of healthcare workers at the clinic because it gave them access to accurate information as well as an environment that made test results seem more credible. Adolescents learned more specific information about living with an HIV-positive status and the meaning of that status from shared experiences among peers at the clinic.HIV-status disclosure to adolescents is distinct from disclosure to younger children and requires tailored, age-appropriate guidelines. Disclosure to this age group in a healthcare setting may help overcome some of the barriers associated with caregivers disclosing in the home environment and make the HIV status seem more credible to an adolescent. The study also highlights the value of peer support among adolescents, which could help reduce the burden of psychosocial care on caregivers and healthcare workers.

    Adolescents with autism spectrum disorder (ASD) spend more time using electronic screen media than neurotypical peers; preliminary evidence suggests that computer-assisted or Web-based interventions may be beneficial for social skills acquisition. The current generation of adolescents accesses the Internet through computers or phones almost daily, and Facebook is the most frequently used social media platform among teenagers. This is the first research study to explore the use of Facebook as a therapeutic tool for adolescents with ASD. To study the feasibility and clinical impact of using a Web-based social platform in combination with social skills training for adolescents with ASD. This pilot study enrolled 6 participants (all males; mean age 14.1 years) in an online social skills training group using Facebook. Data was collected on the participants' social and behavioral functioning at the start and conclusion of the intervention. Outcome measures included the Social Responsiveness Scale-2, the Social Skills Improvement System Rating Scale, and the Project Rex Parent Survey. Participants were surveyed at the conclusion of the intervention regarding their experience. No statistically significant differences in measurable outcomes were observed. However, the online addition of Facebook was well received by participants and their parents. The Facebook intervention was able to be executed with a careful privacy protocol in place and at minimal safety risk to participants. The utilization of Facebook to facilitate delivery of social skills training for adolescents with ASD appears to be feasible, although the clinical impact of such an addition is still unclear. It is important to note that social difficulties of participants persisted with the addition of the online platform and participants still required assistance to engage with peers in an online environment. A Web-based intervention such as the one utilized in this study has the potential to reach a mass number

    Full Text Available Background: Physical activity is important for adolescent health. The current study aimed to explore factors that predict physical activity among adolescents. Methods: This was a cross-sectional study of physical activity among a sample of adolescents in Tabriz, Iran. Information on physical activity was collected using a modified version of the Adolescent Physical Activity and Recall Questionnaire (APARQ. In addition, a self-administrated questionnaire was used to collect data on demographic characteristics, perceived family support, and self-efficacy. Both univariate and multivariate logistic regression analyses were performed to examine the association between physical activity and independent variables including gender and psychosocial predictors. Results: In all, 402 students were studied. The mean age of adolescents was 12.93 (SD=0.49 years; 51.5% were female. The mean time of moderate and vigorous physical activity for all adolescents was 44.64 (SD=23.24 Metabolic Equivalent (MET min per day. This figure for female adolescents was 38.77 (SD=19.94 MET min per day and for males it was 50.87 (SD=24.88 (P<0.001. The results obtained from multiple logistic regression analysis indicated that female gender (OR=2.59, 95% CI=1.46–4.57, P=0.001 and poor family support (OR=1.10, 95% CI=1.03–1.20, P=0.038 were the most significant contributing factors to low level physical activity in adolescents. Other variables studied did not show any significant results. Conclusion: The findings from the current study indicated that female adolescents were at risk of lower level of physical activity. In addition, it was found that the lack of family support represented an increased risk for low-level physical activity. It seems that family support should be an integrated part of any health education/promotion programs for improving physical activity among young adolescents in general and for female adolescents in particular.

    Group-based social skills training (SST) has repeatedly been recommended as treatment of choice in high-functioning autism spectrum disorder (HFASD). To date, no sufficiently powered randomised controlled trial has been performed to establish efficacy and safety of SST in children and adolescents with HFASD. In this randomised, multi-centre, controlled trial with 220 children and adolescents with HFASD it is hypothesized, that add-on group-based SST using the 12 weeks manualised SOSTA-FRA program will result in improved social responsiveness (measured by the parent rated social responsiveness scale, SRS) compared to treatment as usual (TAU). It is further expected, that parent and self reported anxiety and depressive symptoms will decline and pro-social behaviour will increase in the treatment group. A neurophysiological study in the Frankfurt HFASD subgroup will be performed pre- and post treatment to assess changes in neural function induced by SST versus TAU. The SOSTA - net trial is designed as a prospective, randomised, multi-centre, controlled trial with two parallel groups. The primary outcome is change in SRS score directly after the intervention and at 3 months follow-up. Several secondary outcome measures are also obtained. The target sample consists of 220 individuals with ASD, included at the six study centres. This study is currently one of the largest trials on SST in children and adolescents with HFASD worldwide. Compared to recent randomised controlled studies, our study shows several advantages with regard to in- and exclusion criteria, study methods, and the therapeutic approach chosen, which can be easily implemented in non-university-based clinical settings.

    2009-11-01

    Full Text Available Abstract Background Childhood obesity is a serious health concern affecting over 155 million children in developed countries worldwide. Childhood obesity is associated with significantly increased risk for development of type 2 diabetes, cardiovascular disease and psychosocial functioning problems (i.e., depression and decreased quality of life. The two major strategies for management of obesity and associated metabolic abnormalities are lifestyle modification and pharmacologic therapy. This paper will provide the background rationale and methods of the REACH childhood obesity treatment program. Methods/design The REACH study is a 2-year multidisciplinary, family-based, childhood obesity treatment program. Seventy-two obese adolescents (aged 10-16 years and their parents are being recruited to participate in this randomized placebo controlled trial. Participants are randomized to receive either metformin or placebo, and are then randomized to a moderate or a vigorous intensity supervised exercise program for the first 12-weeks. After the 12-week exercise program, participants engage in weekly exercise sessions with an exercise facilitator at a local community center. Participants engage in treatment sessions with a dietitian and social worker monthly for the first year, and then every three months for the second year. The primary outcome measure is change in body mass index and the secondary outcome measures are changes in body composition, risk factors for type 2 diabetes and cardiovascular disease, changes in diet, physical activity, and psychosocial well-being (e.g., quality of life. It is hypothesized that participants who take metformin and engage in vigorous intensity exercise will show the greatest improvements in body mass index. In addition, it is hypothesized that participants who adhere to the REACH program will show improvements in body composition, physical activity, diet, psychosocial functioning and risk factor profiles for type 2

    Full Text Available Background. Data regarding depression and resilience among adolescents is still lacking. Objective. To assess depressive symptoms and resilience among pregnant adolescents. Method. Depressive symptoms and resilience were assessed using two validated inventories, the 10-item Center for Epidemiologic Studies Short Depression Scale (CESD-10 and the 14-item Wagnild and Young Resilience Scale (RS, respectively. A case-control approach was used to compare differences between adolescents and adults. Results. A total of 302 pregnant women were enrolled in the study, 151 assigned to each group. Overall, 56.6% of gravids presented total CESD-10 scores 10 or more indicating depressed mood. Despite this, total CESD-10 scores and depressed mood rate did not differ among studied groups. Adolescents did however display lower resilience reflected by lower total RS scores and a higher rate of scores below the calculated median (P<.05. Logistic regression analysis could not establish any risk factor for depressed mood among studied subjects; however, having an adolescent partner (OR, 2.0 CI 95% 1.06–4.0, P=.03 and a preterm delivery (OR, 3.0 CI 95% 1.43–6.55, P=.004 related to a higher risk for lower resilience. Conclusion. In light of the findings of the present study, programs oriented at giving adolescents support before, during, and after pregnancy should be encouraged.

    Most studies on parent-adolescent sexual health communication come from developed countries and are based on either parents' or children's reports. In developing countries, there is little evidence about the agreement among reports of all parties involved in parent-adolescent sexual health communication. The objective of this study is to explore the congruence (agreement) between adolescents and their parents about how frequently they discuss on selected sexual health topics. A total of 1606 parent-adolescent dyads of adolescents attending the first year in public high schools and their parents, in Morelos, Mexico were sampled in this study. The participants completed a self-administered questionnaire that included the frequency of parent-adolescent communication about eight sexual health topics. An ordinal logistic threshold model was used to estimate intra-class correlation coefficients within parent-adolescent dyads (as a measure of congruence) and to test if thresholds were equal between parents and adolescents. Congruence in reported frequency of parent-adolescent sexual health communication ranged from 0.205 (menstruation) to 0.307 (condoms) for mother-adolescent dyads, and from 0.103 (ejaculation) to 0.380 (condoms) for father-adolescent dyads. The thresholds (i.e., the cutoff points that define the categories in the observed ordinal variable) differed between parents and adolescents for each of the sexual health topics explored (pcongruence between parents' and adolescents' reports on parent-adolescent sexual health communication. This might be due to interpretation of frequency and intensity of sexual health communication which differs between parents and adolescents.

However, only few works have considered what happens when the established keys are actually used—to run some protocol securely over the established “channel”. We call this a vertical protocol.......e., that the combination cannot introduce attacks that the individual protocols in isolation do not have. In this work, we prove a composability result in the symbolic model that allows for arbitrary vertical composition (including self-composition).

B-mode ultrasound was employed to study 40 ovarian lesions in 37 girls between the age of 6 and 17 years complaining of acute pelvic pain of ovarian origin. Thirteen of the lesions were also assessed by color Doppler ultrasound. We found 25 cases of hemorrhagic cysts, 8 of simple cyst and 7 of ovarian torsion. Surgical and pathological correlation was established in 17 cases (7 cases hemorrhagic cyst, 3 of simple cysts and 7 of ovarian torsion). The remaining lesions are being followed by clinical and ultrasonographic monitoring. Simple and hemorrhagic cysts presenting the so called hematocrit effect are easily diagnosed by B-mode ultrasound. The ultrasonographic features of torsion and certain hemorrhagic cysts are similar on occasion, and surgery and histologic assessment are necessary for the definitive diagnosis. Doppler ultrasound provides no additional information to aid in the diagnosis of these lesions. (Author) 28 refs

    We study the effect of routing protocols on the performance of media access control (MAC) protocols in wireless radio networks. Three well known MAC protocols: 802.11, CSMA, and MACA are considered. Similarly three recently proposed routing protocols: AODV, DSR and LAR scheme 1 are considered. The experimental analysis was carried out using GloMoSim: a tool for simulating wireless networks. The main focus of our experiments was to study how the routing protocols affect the performance of the MAC protocols when the underlying network and traffic parameters are varied. The performance of the protocols was measured w.r.t. five important parameters: (i) number of received packets, (ii) average latency of each packet, (iii) throughput (iv) long term fairness and (v) number of control packets at the MAC layer level. Our results show that combinations of routing and MAC protocols yield varying performance under varying network topology and traffic situations. The result has an important implication; no combination of routing protocol and MAC protocol is the best over all situations. Also, the performance analysis of protocols at a given level in the protocol stack needs to be studied not locally in isolation but as a part of the complete protocol stack. A novel aspect of our work is the use of statistical technique, ANOVA (Analysis of Variance) to characterize the effect of routing protocols on MAC protocols. This technique is of independent interest and can be utilized in several other simulation and empirical studies.

    Chinese adolescents are increasingly engaging in romantic experiences and high-risk sexual behaviors within a rapidly-changing cultural and socio-economic context. Parental communication about sexuality has been recognized as protective for adolescents to make informed decisions about sexual practice. In this study, we explored what was discussed about adolescent romantic experience between parents and adolescents in China. Twenty-seven parents and 38 adolescents from a northern-eastern city of China were interviewed. Interviews were transcribed verbatim and thematically analyzed using a social constructionism framework. Four themes were identified: (i) detriments of romantic experience to education and future prospect; (ii) health and sociocultural risks of romantic and sexual engagement; (iii) ways of handling romantic experience; and (iv) marriage and family building. The messages were mainly prohibitive and consequence oriented in nature, and lacked specific romantic and sexual information. These messages reflected sociocultural beliefs in education, sexuality, marriage, and family in China, but did not meet the needs of current adolescents. External support from health professionals, such as nurses, is important for parents and adolescents to improve their sexual knowledge and communication skills. © 2017 John Wiley & Sons Australia, Ltd.

    Adolescent mental health problems are associated with a range of adverse outcomes in adulthood but little is known about the effects on adult parenting practices. This study aimed to examine prospective associations between adolescent conduct and emotional problems and subsequent parenting behaviours in adulthood. The study sample comprised 1110 members from the MRC National Survey of Health and Development. Prospective data were collected from teacher reports of conduct and emotional problems at age 13 and 15 years and adult outcome measures of parenting included intellectual environment, cognitive stimulation, coercive discipline, parental interest and parental aspiration. In regression models adjusted for the confounding effects of social background, cognition and education, adolescent conduct problems predicted coercive parenting behaviours in adulthood. The effects of adolescent emotional problems on the development of coercive discipline practices were explained by covariates. Likewise, the inability of parents who displayed conduct problems in adolescence to provide an intellectually stimulating home environment was fully explained by the adjustment for education. Adolescents who exhibit conduct problems are more likely to develop coercive styles of parenting.

    Purpose: Cardiomyopathy is a rare but life-threatening disease in children and adolescents. Recent studies reported morphological, functional or metabolic alterations of the heart. We discuss a combined MR imaging and 31 P MR spectroscopy (MRS) protocol allowing the analysis of interdependencies between these parameters. Since normal values of cardiac MR parameters in this age group are not available, we included studies of age-matched healthy adolescents. Materials and Methods: 2D-CINE was used to assess left ventricular (LV) parameters. Additional 3D-Chemical Shift Imaging (3D-CSI) and Spectral Localization with Optimal Pointspread Function (SLOOP) reconstruction allowed quantification of the cardiac energy metabolism. Patients (n = 4; all male; age 16.8 ± 2.9 years) were included on the basis of an echocardiographic diagnosis of possible cardiomyopathy. The same protocol was applied to healthy young volunteers (n = 4; 1 female, 3 male; age 15.5 ± 0.6 years). Results: The patients had a significantly higher LV mass index compared to the control group (147 ± 41 g/m2 versus 97 ± 16 g/m2; p = 0.04). The other LV parameters (including LV EF with 59 ± 22 % versus 67 ± 10 %) showed no significant differences. The phosphocreatine to adenosine triphosphate ratio (PCr/ATP-ratio) of the patients was reduced to 1.71 ± 0.40 versus 2.44 ± 0.30 (p = 0.01), combined with a tendency towards decreased PCr concentrations of 9.1 ± 2.5 versus 7.9 ± 1.0 mmol/kg. Conclusion: The combination of 31 P MR spectroscopy and MR imaging allows quantitative determination of morphologic, functional and metabolic alterations in adolescents with suspected cardiomyopathy in one examination procedure. The reduction of energy metabolism combined with unaltered global function may indicate a primary role of metabolism in the pathogenesis of cardiomyopathies in adolescents. (orig.)

    The prognosis, in the long term, of adolescents and young adults with acute de novo lymphoblastic leukemia, treated with a pediatric type protocol. To analyze the efficacy and tolerability of a chemotherapy regimen of pediatric type on patients 15-35 years old with de novo acute lymphoblastic leukemia, Ph(-). A retrospective study of patients received from 2001 to 2013, without initial infiltration of the central nervous system. They received the regimen called LALÍN. Terminal goals: frequency of initial remission, probability of survival free of leukemia and event-free survival for five years. We included 101 patients; there were 29 relapses and 19 deaths. There was initial remission in 97% of the cases; survival free of leukemia of 0.58 and event-free survival 0.44. No difference in patients aged 16-21 years vs. 22-35 (p > 0.55). Negative prognostic factors: abnormal karyotypes, except hyperdiploids (p = 0.001); > 5% of blasts, on 14 day induction (p = 0. 0001); delay in the punctuality of the courses of the chemotherapy regimen (p = 0.0001). A pediatric type regimen is applicable to patients aged from 16 to 35 years with acute lymphoblastic leukemia, without greater toxicity and a best survival free of leukemia. The count of > 5% of blasts and the delay in the execution of the stages of the chemotherapy regimen are the stronger negative prognostic factors.

    Previous studies have indicated the parent-adolescent relationship has a correlation to adolescents' premarital sex behavior risk. Therefore, the aim of this study was to discover the influence of parent-adolescent communication on adolescents' risk of sexual issues. This was a quantitative study with a cross-sectional design. The population of this study consisted of students from a high school in Jakarta. A purposive sampling technique was used, which resulted in the selection of 253 students as samples. A PACS (Parent-Adolescent Communication Scale) questionnaire was applied. The results showed that 59.3% of the adolescents studied were at risk for engaging in premarital sex, while the risk for adolescents with positive communication with their parents was 56.5%. Bivariate analysis also showed a significant correlation between gender and parent-adolescent communication and the risk of adolescent premarital sex behavior (α adolescents. Communication must align with adolescents' developmental tasks. Nurses can also create a promotion program on the topic of communication for parents and adolescents.

    Full Text Available Abstract Background Group-based social skills training (SST has repeatedly been recommended as treatment of choice in high-functioning autism spectrum disorder (HFASD. To date, no sufficiently powered randomised controlled trial has been performed to establish efficacy and safety of SST in children and adolescents with HFASD. In this randomised, multi-centre, controlled trial with 220 children and adolescents with HFASD it is hypothesized, that add-on group-based SST using the 12 weeks manualised SOSTA–FRA program will result in improved social responsiveness (measured by the parent rated social responsiveness scale, SRS compared to treatment as usual (TAU. It is further expected, that parent and self reported anxiety and depressive symptoms will decline and pro-social behaviour will increase in the treatment group. A neurophysiological study in the Frankfurt HFASD subgroup will be performed pre- and post treatment to assess changes in neural function induced by SST versus TAU. Methods/design The SOSTA – net trial is designed as a prospective, randomised, multi-centre, controlled trial with two parallel groups. The primary outcome is change in SRS score directly after the intervention and at 3 months follow-up. Several secondary outcome measures are also obtained. The target sample consists of 220 individuals with ASD, included at the six study centres. Discussion This study is currently one of the largest trials on SST in children and adolescents with HFASD worldwide. Compared to recent randomised controlled studies, our study shows several advantages with regard to in- and exclusion criteria, study methods, and the therapeutic approach chosen, which can be easily implemented in non-university-based clinical settings.

    Background Although the number of smokers has declined in the last decade, smoking is still a major health problem among youngsters and adolescents. For this reason, there is a need for effective smoking prevention programmes targeting primary school children. A web-based computer-tailored feedback programme may be an effective intervention to stimulate youngsters not to start smoking, and increase their knowledge about the adverse effects of smoking and their attitudes and self-efficacy regarding non-smoking. Methods & design This paper describes the development and evaluation protocol of a web-based out-of-school smoking prevention programme for primary school children (age 10-13 years) entitled ‘Fun without Smokes’. It is a transformation of a postal mailed intervention to a web-based intervention. Besides this transformation the effects of prompts will be examined. This web-based intervention will be evaluated in a 2-year cluster randomised controlled trial (c-RCT) with three study arms. An intervention and intervention + prompt condition will be evaluated for effects on smoking behaviour, compared with a no information control condition. Information about pupils’ smoking status and other factors related to smoking will be obtained using a web-based questionnaire. After completing the questionnaire pupils in both intervention conditions will receive three computer-tailored feedback letters in their personal e-mail box. Attitudes, social influences and self-efficacy expectations will be the content of these personalised feedback letters. Pupils in the intervention + prompt condition will - in addition to the personalised feedback letters - receive e-mail and SMS messages prompting them to revisit the ‘Fun without Smokes’ website. The main outcome measures will be ever smoking and the utilisation of the ‘Fun without Smokes’ website. Measurements will be carried out at baseline, 12 months and 24 months of follow-up.

    Many studies of sexual messages in media utilize content analysis methods. At times, this research assumes that researchers and trained coders using content analysis methods and the intended audience view and interpret media content similarly. This article compares adolescents' perceptions of the presence or absence of sexual content on television to those of researchers using three different coding schemes. Results from this formative research study suggest that participants and researchers are most likely to agree with content categories assessing manifest content, and that differences exist among adolescents who view sexual messages on television. Researchers using content analysis methods to examine sexual content in media and media effects on sexual behavior should consider identifying how audience characteristics may affect interpretation of content and account for audience perspectives in content analysis study protocols when appropriate for study goals.

This study evaluates the impact and sustainability of a competitive voucher program on the quality of SRH care for poor and underserved female adolescents and the usefulness of the simulated patient (SP method for such evaluation. Methods 28,711 vouchers were distributed to adolescents in disadvantaged areas of Managua that gave free-of-charge access to SRH care in 4 public, 10 non-governmental and 5 private clinics. Providers received training and guidelines, treatment protocols, and financial incentives for each adolescent attended. All clinics were visited by female adolescent SPs requesting contraception. SPs were sent one week before, during (with voucher and one month after the intervention. After each consultation they were interviewed with a standardized questionnaire. Twenty-one criteria were scored and grouped into four categories. Clinics' scores were compared using non-parametric statistical methods (paired design: before-during and before-after. Also the influence of doctors' characteristics was tested using non-parametric statistical methods. Results Some aspects of service quality improved during the voucher program. Before the program started 8 of the 16 SPs returned 'empty handed', although all were eligible contraceptive users. During the program 16/17 left with a contraceptive method (p = 0.01. Furthermore, more SPs were involved in the contraceptive method choice (13/17 vs.5/16, p = 0.02. Shared decision-making on contraceptive method as well as condom promotion had significantly increased after the program ended. Female doctors had best scores before- during and after the intervention. The improvements were more pronounced among male doctors and doctors older than 40, though these improvements did not sustain after the program ended. Conclusion This study illustrates provider

    The National Health & Morbidity Survey (NHMS) IV (2011) observed that the prevalence of obese children aged less than 18 years in Malaysia is 6.1% compared to 5.4% overweight and obese in NHMS III (2006). As such, this observation is of public health importance as obesity is a forewarning risk factor for chronic diseases such as type-2 diabetes, cardiovascular diseases (CVD) and certain types of cancers. This MyHeART (Malaysian Health and Adolescents longitudinal Research Team) study aims to examine risk factors of non-communicable diseases (NCD) among adolescents. The MyHeART study is longitudinal cohort study of 1361 schoolchildren (13-years old) attending 15 public secondary schools from the central (Kuala Lumpur and Selangor) and northern (Perak) regions of Peninsular Malaysia. The study used a stratified sampling design to select the study participants. Data collected at baseline included socio-economic, lifestyle (e.g. smoking, physical activity assessment, fitness assessment, seven-day diet history), and environmental information, anthropometric measurements, blood pressure, handgrip strength and bone mineral density. Blood samples for fasting blood glucose and lipid profiles, full blood count, renal profile, as well as bone profile and serum vitamin D were taken. This study cohort will be followed up again when participants turn 15, 17 and lastly, after a period of ten years (around the age of 27). Nine percent of the adolescents from this study were obese. More male participants smoked compared to female participants (15.4% vs. 4.7%). Adolescent males had higher fasting blood glucose but the female participants had lower high density lipoprotein (HDL-cholesterol) and higher low density lipoprotein (LDL-cholesterol). In addition, adolescents from the rural area had higher fasting blood glucose, diastolic blood pressure, total cholesterol and LDL-cholesterol. Our results demonstrated that adolescents from the rural area are at higher risk of NCDs compared to

    Optimal nutrition is essential for healthy growth during adolescence. This study aims to investigate the baseline nutritional intake of Malaysian adolescents by gender, body mass index, and places of residence, both urban and rural. A cohort study was conducted consisting of 794 adolescents (aged 13-years) attending 15 public secondary schools from the Central (Kuala Lumpur and Selangor) and Northern (Perak) Regions of Peninsular Malaysia. Qualified dietitians conducted a 7-day historical assessment of habitual food intakes. Facilitated by flipcharts and household measurement tools, detailed information on portion sizes and meal contents were recorded. Nutritionist Pro™ Diet Analysis software was also used to analyze the dietary records.The mean age of the adolescents was 12.86 ± 0.33 y; the mean energy intake was 1659.0 ± 329.6 kcal/d. Males had significantly (P < .001) higher energy intake than females (1774.0 ± 369.8 vs 1595.2 ± 320.6 kcal/d); adolescents in rural schools consumed more energy and cholesterol (P < .001) compared to adolescents in urban schools (1706.1 ± 377.7 kcal/d and 244.1 ± 100.2 mg/d, respectively). Obese adolescents in rural schools consumed more energy and sugar (1987.6 ± 374.0 kcal/d and 48.9 ± 23.0 g/d) (p-value <0.001).The dietary intake of normal weight versus obese adolescents differs by the location of their school. Thus, the implementation of a structured and tailored intervention is recommended to help minimize this nutritional inequality.

    There are minimal data on the use of electroconvulsive therapy (ECT) in adolescents from India. The present study aimed to evaluate the clinical profile and effectiveness of ECT in adolescents (aged 13-18 years). A retrospective chart review was carried out to identify adolescents (aged 13-18 years) who had received ECT during the period 1999-2011. During the study period, 39 such patients received ECT; complete records of 25 patients were available. Details regarding their sociodemographic, clinical, and treatment data were extracted from these records for the present study. During the study period, 658 patients received ECT, of which 39 were aged 18 or younger (5.9%). Schizophrenia (n = 14; 56%) was the commonest diagnosis for which ECT was used in adolescents, followed by depression (n = 3; 12%). Catatonic symptoms (n = 17; 68%) were the most common symptoms among these subjects. Electroconvulsive therapy was considered as a treatment of choice taking the clinical picture account in about three fourths of the patients (n = 19; 76%). The mean (SD) numbers of ECTs administered per patient were 10.1 (4.87) (range, 2-21). The mean (SD) response rate to ECT was 76% (23.3%) (range, 31%-100%). Response rates according to diagnosis were the following: 76.3% for schizophrenia, 87.2% for depression, 81.8% for psychosis (not otherwise specified), and 77.7% for acute and transient psychosis. Response rate in patients with catatonia was 91.6%. Prolonged seizures, nausea and vomiting, and headache were reported in 2 cases each. Electroconvulsive therapy is used less frequently in children and adolescents compared to the older patients. This study shows that ECT is effective in the treatment of severe psychiatric disorders in adolescents and is associated with the same frequency of adverse effects as the adults.

    There is a high incidence of anterior cruciate ligament (ACL) injury in adolescents participating in pivoting sports such as soccer, basketball, and handball. Most ACL injuries in athletes are noncontact injuries, with a mechanism of sudden deceleration, change in direction, or landing from a jump. These mechanisms coupled with an increase in contraction of the quadriceps have been shown as risk factors for ACL injuries. Injuries to the ACL may require surgery, a long rehabilitation, and the potential for reinjury. Studies have shown reductions in lower extremity injury rates using training protocols that focus on landing mechanics, balance training, strength training, and/or agility training. There has been some thought that starting preventive training programs with adolescent athletes may be the most effective approach to reducing adolescent ACL injuries. Can lower extremity injury-prevention programs effectively reduce ACL injury rates in adolescent athletes?

    We have limited understanding of the precursors of academic achievement in resettled adolescents from refugee backgrounds. To date, no clear model has been developed to conceptualise the academic trajectories of adolescents from refugee backgrounds at postsettlement. The current review had two aims. First, to propose an integrated adaptive model to conceptualise the impact of individual, premigration, and postsettlement factors on academic achievement at postsettlement; and second, to critically examine the literature on factors that predict academic achievement in adolescents from refugee backgrounds in relation to the proposed model and highlight issues deserving future exploration. Following the protocol of a systematic literature review, 13 studies were identified for full-text review. Gender, ethnicity, English proficiency, psychological distress, premigration trauma, premigration loss, postsettlement social support, and postsettlement school connectedness, were found to predict academic achievement in adolescents from refugee backgrounds.

    Full Text Available Abstract Background It is currently unknown if school-based social norms interventions are effective in preventing harmful alcohol consumption and other drug use among adolescents in Denmark. This paper describes the social norms-based programme The GOOD life and the design of a cluster-randomized controlled trial to test its effectiveness. Methods/Design The intervention The GOOD life is composed of three social norms components representing three different communication channels, namely face-to-face communication (normative feedback session, print communication (posters and interactive media (web application. The intervention period of 8 weeks is preceded and followed by data collection, with the follow-up taking place 3 months after baseline. Public schools in the Region of Southern Denmark with grades 8 and 9 are invited to participate in the study and participating schools are randomly allocated to either intervention or control schools. The aim is to recruit a total of 39 schools and a sample of 1.400 pupils for the trial. An online questionnaire is conducted to examine the use of alcohol, tobacco and marijuana as well as the perceived frequency of use among peers of their own grade, which is measured before and after the intervention. Baseline data is used to develop social norms messages which are included in the three intervention components. Primary outcomes are binge drinking (more than 5 units at one occasion and perceived frequency of binge drinking among peers, while smoking, marijuana use and alcohol-related harm will be assessed as secondary outcomes. Discussion The GOOD life study will provide necessary insights on descriptive and injunctive norms regarding alcohol and other drug use among Danish adolescents. In addition, it will provide new knowledge and insight on the feasibility, implementation context and effectiveness of a newly developed social norms intervention in the Danish school context.

    Practice-based studies are needed to assess how physicians communicate health messages about weight to overweight/obese adolescent patients, but successful recruitment to such studies is challenging. This paper describes challenges, solutions, and lessons learned to recruit physicians and adolescents to the Teen Communicating Health Analyzing Talk (CHAT) study, a randomized controlled trial of a communication skills intervention for primary care physicians to enhance communication about weight with overweight/obese adolescents. A "peer-to-peer" approach was used to recruit physicians, including the use of "clinic champions" who liaised between study leaders and physicians. Consistent rapport and cooperative working relationships with physicians and clinic staff were developed and maintained. Adolescent clinic files were reviewed (HIPAA waiver) to assess eligibility. Parents could elect to opt-out for their children. To encourage enrollment, confidentiality of audio recordings was emphasized, and financial incentives were offered to all participants. We recruited 49 physicians and audio-recorded 391 of their overweight/obese adolescents' visits. Recruitment challenges included 1) physician reticence to participate; 2) variability in clinic operating procedures; 3) variability in adolescent accrual rates; 4) clinic open access scheduling; and 5) establishing communication with parents and adolescents. Key solutions included the use of a "clinic champion" to help recruit physicians, pro-active, consistent communication with clinic staff, and adapting calling times to reach parents and adolescents. Recruiting physicians and adolescents to audio-recorded, practice-based health communication studies can be successful. Anticipated challenges to recruiting can be met with advanced planning; however, optimal solutions to challenges evolve as recruitment progresses.

  20. Changes in adolescents' conflict responses associated with consecutive presentation of hypothetical conflict situations.

    The advantages of using hypothetical situations are one reason they have been widely used to examine adolescents' responses to conflict situations. One frequently used research protocol involves presenting several conflict scenarios to participants during a single session. However, in real-life situations multiple conflicts rarely occur within short periods of time, and the nature of this presentation may be associated with changes in adolescents' reports of conflict behaviors. Trend analyses of emotional, conflict goal, and conflict tactic responses from grade 8, 10, 12, and college students to consecutively presented conflict situations showed that responses were associated with presentation of the hypothetical situations. Findings revealed an increase in reports of assertive conflict behaviors and a decrease in reports of constructive conflict behaviors with successive situation presentation. Results from the current study suggest that researchers must consider trends in responses when examining findings from successive situation presentation methodologies because adolescent reports of conflict behavior may change as situation presentation proceeds.

    Menstruation is a natural phenomenon that occurs throughout the reproductive life of every woman. The aim of this study was to explore knowledge and self-care practices among Palestinian adolescent girls during their menstrual period. Reproductive health issues in adolescent girls is an important but neglected area of Palestinian research. For this cross-sectional study we recruited girls from grades seven, eight, and nine in the three biggest schools for girls in Nablus district. Participants were given a self-administered questionnaire that included questions about diet habits, daily activity, medication usage, and social norms related to the menstrual period. Data were analysed using SPSS version 17. The study protocol was approved ethically by Ibn Sina College for Health Sciences board. Verbal informed consent was obtained from the participants. 100 girls completed the questionnaire. 68 (68%) respondents referred to their mothers as the main source of information about dealing with menstrual periods. 52 (52%) respondents believed that salty food affects adversely on their health during the menstrual period, and 85 (85%) answered that showering is important during menstruation and that no harm comes from touching things during menstruation. 38 (38%) girls did not change food quality or quantity during menstruation, and 36 (36%) girls often take hot herbal drinks to relieve menstrual pain, whereas 63 (63%) girls reported use of analgesics. 94 (94%) respondents had a proper way of disposing of dirty pads. 45 (45%) girls said they used school toilets, 70 (70%) mentioned the availability of private doors, and 60 (60%) reported the availability of soap and water. Self-care practices during menstruation could be improved in adolescent Palestinian girls by establishing comprehensive puberty education programmes in schools and providing appropriate sanitation conditions in school toilets.

    The aim of this study was to compare the effects of Animal-Assisted Therapy (AAT) with a standard treatment protocol in children and adolescents admitted to the psychiatry hospital for acute mental disorders. We used a methodology involving high quality standards for AAT research. A pre-post experimental design with a randomized controlled trial (RCT) in 34 hospitalized patients (17 treatment, 17 control) was carried out. The study focused on improvement in clinical status including, global functioning measured by the Children Global Assessment Scale (C GAS), format of care and ordinary school attendance measured by a rating scale. Our results indicate a statistically significant improvement in global functioning, reduction in format of care and increased ordinary school attendance in the treatment group, but not in the control group. Our results verify that AAT can have significant positive effects on therapeutic progress and the recovery process. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available Studies suggest marijuana impacts gray and white matter neural tissue development, however few prospective studies have determined the relationship between cortical thickness and cannabis use spanning adolescence to young adulthood. This study aimed to understand how heavy marijuana use influences cortical thickness trajectories across adolescence. Subjects were adolescents with heavy marijuana use and concomitant alcohol use (MJ + ALC, n = 30 and controls (CON, n = 38 with limited substance use histories. Participants underwent magnetic resonance imaging and comprehensive substance use assessment at three independent time points. Repeated measures analysis of covariance was used to look at main effects of group, time, and Group × Time interactions on cortical thickness. MJ + ALC showed thicker cortical estimates across the brain (23 regions, particularly in frontal and parietal lobes (ps < .05. More cumulative marijuana use was associated with increased thickness estimates by 3-year follow-up (ps < .05. Heavy marijuana use during adolescence and into young adulthood may be associated with altered neural tissue development and interference with neuromaturation that can have neurobehavioral consequences. Continued follow-up of adolescent marijuana users will help understand ongoing neural changes that are associated with development of problematic use into adulthood, as well as potential for neural recovery with cessation of use.

    Although concurrent influences on adolescent physical activity are well documented, longitudinal studies offer additional insights about early life antecedents of participation. The aim of this study was to examine associations between childhood and contemporaneous factors and patterns of physical activity participation during adolescence. Physical activity participation at ages 15 and 18 was assessed among members of the Dunedin Multidisciplinary Health and Development Study cohort using the interview-based Minnesota Leisure Time Physical Activity Questionnaire. Logistic regression was used to examine associations between childhood factors (socioeconomic status, family "active-recreation" orientation, home activities, motor ability, intelligence, and psychiatric disorder), contemporaneous factors (parental health, body mass index, predicted VO(2 max), general health, television viewing, smoking, and alcohol use) and "persistent inactivity," "declining participation," or "persistent activity" during adolescence. In multivariate models, persistent inactivity during adolescence was associated with lower childhood family active-recreation orientation, and poorer cardiorespiratory fitness and general health during adolescence. Declining participation was more likely among those who reported fewer activities at home during childhood. Persistent activity was associated with better cardiorespiratory fitness and watching less television during adolescence. This study found that childhood and contemporaneous factors were associated with persistent inactivity, persistent activity and declining participation during adolescence. The findings highlight several factors from the family and home environment of potential importance in early intervention programs to support adolescent participation in physical activity.

    Body dysmorphic disorder (BDD) is a relatively common and severe disorder that typically onsets in adolescence, but often goes unrecognized. Despite BDD's severity and early onset, treatment outcome research on adolescent BDD is scarce. Cognitive-behavioral therapy is the gold-standard psychosocial treatment for BDD in adults and has shown promise in adolescents. The current study examined the development and testing of a new CBT for adolescents with BDD. We tested feasibility, acceptability, and treatment outcome in a sample of 13 adolescents (mean age 15.23years, range: 13-17) with primary BDD. Treatment was delivered in 12-22 weekly individual sessions. Standardized clinician ratings and self-report measures were used to assess BDD and related symptoms pre- and posttreatment and at 3- and 6-months follow-up. At posttreatment, BDD and related symptoms (e.g., insight, mood) were significantly improved. Scores on the Yale-Brown Obsessive Compulsive Scale for BDD indicated a 50% (intent-to-treat) and 68% (completer) improvement in BDD symptoms. Seventy-five percent of adolescents who started treatment and 100% of completers were considered treatment responders. Treatment gains were maintained at follow-up. High patient satisfaction ratings and patient feedback indicated that treatment was acceptable. This represents the largest study of a psychosocial treatment for adolescent BDD. Copyright © 2015.

    Videofluoroscopic swallow study (VFSS) is the gold standard for diagnosis of dysphagia in veterinary medicine but lacks standardized protocols that emulate physiologic feeding practices. Age impacts swallow function in humans but has not been evaluated by VFSS in dogs. To develop a protocol with custom kennels designed to allow free-feeding of 3 optimized formulations of contrast media and diets that address limitations of current VFSS protocols. We hypothesized that dogs evaluated by a free-feeding VFSS protocol would show differences in objective swallow metrics based on age. Healthy juvenile, adult, and geriatric dogs (n = 24). Prospective, experimental study. Custom kennels were developed to maintain natural feeding behaviors during VFSS. Three food consistencies (thin liquid, pureed food, and dry kibble) were formulated with either iohexol or barium to maximize palatability and voluntary prehension. Dogs were evaluated by 16 swallow metrics and compared across age groups. Development of a standardized VFSS protocol resulted in successful collection of swallow data in healthy dogs. No significant differences in swallow metrics were observed among age groups. Substantial variability was observed in healthy dogs when evaluated under these physiologic conditions. Features typically attributed to pathologic states, such as gastric reflux, were seen in healthy dogs. Development of a VFSS protocol that reflects natural feeding practices may allow emulation of physiology resulting in clinical signs of dysphagia. Age did not result in significant changes in swallow metrics, but additional studies are needed, particularly in light of substantial normal variation. Copyright © 2017 The Authors.

    This study investigated young adolescents' perceptions of their peers' prosocial behaviours. In eight focus groups, 53 11- to 13-year olds described specific prosocial acts of their peers. Results suggest that traditional research has not addressed the diversity of prosocial behaviours that youth enact, nor emphasized behaviours that are salient to young adolescents. Such behaviours included standing up for others, encouraging others, helping others develop skills, including others who are left out, and being humorous. Facilitating emotional regulation of others emerged as an important component of prosocial behaviour. These data can help guide future research on prosocial development to include a broader array of authentic behaviours of young adolescents.

    Pain in adolescence is associated with mental health problems, the main reason for work disability in young adults. This study explores the relationship between multisite musculoskeletal pain in adolescence and later medical (sickness and medical rehabilitation benefits) and social welfare benefits, adjusted for sociodemographic, adolescent psychosocial and mental health problems. Data were obtained by linkage between the National Insurance Registry (2003-11) and the Norwegian Arctic Adolescent Health Study, a school-based survey in North Norway (2003-05), accepted by 3987 fifteen- to sixteen-year-olds (68% of the total population). The start of the follow-up time was July 1st of the corresponding year the participants responded to the health study. Musculoskeletal pain was measured by the number of musculoskeletal pain sites. We found a positive linear relationship between adolescent musculoskeletal pain sites and the occurrence of medical and social welfare benefits in young adulthood (p ≤ 0.001). Adolescent musculoskeletal pain was a significant predictor of sickness (p adolescent psychosocial and mental health problems. The most important adolescent psychosocial predictors were externalizing problems, less parental involvement and adverse life events. Adolescent multisite musculoskeletal pain was found to be an important predictor of later sickness and social welfare benefit receipt from adolescence to young adulthood. Adolescents with multisite musculoskeletal pain are at substantially increased risk of health and social difficulties into young adulthood. Identification and interventions for these adolescent problems could alleviate this risk and be a sound socioeconomic investment. © 2017 European Pain Federation - EFIC®.

    Despite the promising evidence supporting positive effects of high-intensity interval training (HIIT) on the metabolic profile in adults, there is limited research targeting adolescents. Given the rising burden of chronic disease, it is essential to implement strategies to improve the cardiometabolic health in adolescence, as this is a key stage in the development of healthy lifestyle behaviours. This narrative review summarises evidence of the relative efficacy of HIIT regarding the metabolic health of adolescents. Methodological inconsistencies confound our ability to draw conclusions; however, there is meaningful evidence supporting HIIT as a potentially efficacious exercise modality for use in the adolescent cohort. Future research must examine the effects of various HIIT protocols to determine the optimum strategy to deliver cardiometabolic health benefits. Researchers should explicitly show between-group differences for HIIT intervention and steady-state exercise or control groups, as the magnitude of difference between HIIT and other exercise modalities is of key interest to public health. There is scope for research to examine the palatability of HIIT as an exercise modality for adolescents through investigating perceived enjoyment during and after HIIT, and consequent long-term exercise adherence.

    Social participation is challenging for people with visual impairments. As a result, on average, social networks are smaller, romantic relationships formed later, educational achievements lower, and career prospects limited. Adolescents on their way towards achieving these goals may benefit from the knowledge and experience of adults who have overcome similar difficulties. Therefore, a mentoring intervention, called Mentor Support, will be set up and studied in which adolescents with visual impairments are matched with successfully social participating adults with and without visual impairments. The main objective of this study is to evaluate the effectiveness of Mentor Support. Secondary aims are to distinguish the importance of the disability-specific experience of mentors, predictors of success, and mediating factors. The effect of Mentor Support will be tested in a randomized clinical trial, using pre-test one week before starting, post-test after 12 months, and follow-up after 18 months. Participants will be referred to one of the experimental groups or the control group, and this randomization will be stratified according to country region. Three groups are included in the trial: 40 participants will receive Mentor Support by mentors with a visual impairment in combination with care-as-usual, 40 participants will receive Mentor Support by mentors without visual impairments in combination with care-as-usual, and 40 participants will receive care-as-usual only. Mentor Support consists of 12 face-to-face meetings of the mentee with a mentor with an overall time period of one year. On a weekly basis, dyads have contact via email, the Internet, or telephone. The primary outcome measure is improved social participation within three domains (work/school, leisure activities, and social relationships). Mediator variables are psychosocial functioning and self-determination. Predictors such as demographics and personality are also investigated in order to distinguish

    Family-based intervention is essential for adolescents with behavioral problems. However, limited data are available on the relationship between family-based factors and adolescent internet addiction (AIA). We aimed to examine this relationship using a representative sample of Shanghai adolescents. In October 2007, a total of 5122 adolescents were investigated from 16 high schools via stratified-random sampling in Shanghai. Self-reported and anonymous questionnaires were used to assess parent-adolescent interaction and family environments. AIA was assessed by DRM-52 Scale, developed from Young's Internet-addiction Scale, using seven subscales to evaluate psychological symptoms of AIA. Adjusting for adolescents' ages, genders, socio-economic status, school performances and levels of the consumption expenditure, strong parental disapproval of internet-use was associated with AIA (vs. parental approval, OR = 2.20, 95% CI: 1.24-3.91). Worse mother-adolescent relationships were more significantly associated with AIA (OR = 3.79, 95% CI: 2.22-6.48) than worse father-adolescent relationships (OR = 1.76, 95% CI: 1.10-2.80). Marital status of "married-but-separated" and family structure of "left-behind adolescents" were associated with symptoms of some subscales. When having high monthly allowance, resident students tended to develop AIA but commuter students did not. Family social-economic status was not associated with the development of AIA. The quality of parent-adolescent relationship/communication was closely associated with the development of AIA, and maternal factors were more significantly associated with development of AIA than paternal factors. Family social-economic status moderated adolescent internet-use levels but not the development of AIA.

    Depression has a heightened prevalence in adolescence, with approximately 15 % of adolescents experiencing a major depressive episode by age 18. Depression in adolescence also poses a risk for future distress and impairment. Despite treatment advances, many adolescents relapse after initial remission. Family context may be an important factor in the developmental trajectory of adolescent depression, and thus in enhancing treatment. This study examined concurrent change over time in adolescent and maternal depressive symptoms in the context of the Treatment of Resistant Depression in Adolescents study. Participants were 334 adolescents (mean age: 16; SD: 1.6; 70 % female, 84 % Caucasian), and their mothers (n = 241). All adolescents were clinically depressed when they entered the study and had received previous selective serotonin reuptake inhibitor (SSRI) treatment. Adolescents received acute treatment for 12 weeks and additional treatment for 12 more weeks. Adolescent depression and suicidal ideation were assessed at 0, 6, 12, 24, 48 and 72 weeks, while maternal depressive symptoms were assessed at 0, 12, 24, 48 and 72 weeks. Latent basis growth curve analyses showed a significant correlation over 72 weeks between trajectories of maternal and adolescent depressive symptoms, supporting the hypothesis of concurrent patterns of change in these variables. The trajectories were correlated more strongly in a subsample that included only dyads in which mothers reported at least one depressive symptom at baseline. Results did not show a correlation between trajectories of maternal depressive symptoms and adolescent suicidal ideation. These findings suggest that adolescent and maternal depressive symptoms change in tandem, and that treatment for adolescent depression can benefit the wider family system. Notably, most mothers in this sample had subclinical depressive symptoms. Future research might explore these trajectories in dyads with more severely depressed mothers.

    Attachment, affect, and sex shape responsivity to psychosocial stress. Concurrent social contexts influence cortisol secretion, a stress hormone and biological marker of hypothalamic–pituitary–adrenal axis activity. Patterns of attachment, emotion status, and sex were hypothesized to relate to bifurcated, that is, accentuated and attenuated, cortisol reactivity. The theoretical framework for this study posits that multiple individual differences mediate a cortisol stress response. The effects of two psychosocial stress interventions, a modified Trier Social Stress Test for Teens and the Frustration Social Stressor for Adolescents were developed and investigated with early adolescents. Both of these protocols induced a significant stress reaction and evoked predicted bifurcation in cortisol responses; an increase or decrease from baseline to reactivity. In Study I, 120 predominantly middle-class, Euro-Canadian early adolescents with a mean age of 13.43 years were studied. The girls' attenuated cortisol reactivity to the public performance stressor related significantly to their self-reported lower maternal-attachment and higher trait-anger. In Study II, a community sample of 146 predominantly Euro-Canadian middle-class youth, with an average age of 14.5 years participated. Their self-reports of higher trait-anger and trait-anxiety, and lower parental attachment by both sexes related differentially to accentuated and attenuated cortisol reactivity to the frustration stressor. Thus, attachment, affect, sex, and the stressor contextual factors were associated with the adrenal-cortical responses of these adolescents through complex interactions. Further studies of individual differences in physiological responses to stress are called for in order to clarify the identities of concurrent protective and risk factors in the psychosocial stress and physiological stress responses of early adolescents.

    Background There exists a dearth of prospective adolescent eating disorder studies with samples that are large enough to detect small or medium sized effects for risk factors, that are generalizable to the broader population, and that follow adolescents long enough to fully capture the period of development when the risk of eating disorder symptoms occurring is highest. As a result, the purpose of this study was to examine psychosocial risk factors for purging for weight control in a national...

    Full Text Available Most of human aggressive behavior occurs in the context of a romantic relationship. Adolescents are not an exception: research show a significant prevalence of dating violence, revealing the need for further study, especially in Latin America, given the lack of research on this topic. This study aims at strengthening knowledge about aggressive behavior in adolescent dating relationships in Costa Rica, taking into account different aggressive behaviors, not only physical or sexual abuse; differences by gender are also analyzed. Based on an ex post facto design, a standardized instrument was used to measure five types of aggressive behavior (i.e., verbal-emotional, physical, sexual, relational and threats in a sample of 468 adolescents from Heredia (Costa Rica. Results show that most participants had committed or suffered aggressions in dating relationships, especially verbal-emotional or both verbal-emotional and sexual abuse, but the mean frequency of reported aggression was low; some significant intersex differences were also found. Results obtained indicate that adolescents have difficulties to deal with conflicts in their romantic relationship; thus this problem needs to be addressed holistically in order to increase the impact of prevention programs for youth.

    At present there is no systematic observation protocol for the assessment of the multi-factorial aspects of physical exposure related to the back used within the constraints of occupational epidemiological research. In this context, a new preliminary systematic observation protocol is proposed to assess exposure to physical loading of the back using nine categories of physical risk factors: the SOPE back protocol. The objective of this study was to investigate whether the new protocol can correctly identify the level of exposure related to measured physical loading of the back. The subjects of this closed cohort study were 451 manual workers at a natural gas distribution company. The assessment of exposure was made with the protocol using groups with different job titles. The workers were followed for a 2 yr period to establish the risk of a new occurrence of complete disability related to the back (NOCD back injury) in each job grouping. Based on the median of the total scores derived from the protocol, two levels of exposure were identified (high and low). Taking into account the limitations of this study, the protocol in development may be a good tool to establish two levels of exposure to physical loading of the back in large epidemiological studies of occupational low back pain. Further research is needed to replicate these results with larger samples and to test the reliability and predictive validity of the protocol.

    The aim of this study was to investigate the influence of ingesting a carbohydrate (CHO) gel on the intermittent endurance capacity and sprint performance of adolescent team games players. Eleven participants [mean age 13.5 ± 0.7 years, height 1.72 ± 0.08 m, body mass (BM) 62.1 ± 9.4 kg] performed two trials separated by 3-7 days. In each trial, they completed four 15 min periods of part A of the Loughborough Intermittent Shuttle Test (LIST), followed by an intermittent run to exhaustion (part B). In the 5 min pre-exercise, participants consumed 0.818 mL kg(-1) BM of a CHO or a non-CHO placebo gel, and a further 0.327 mL kg(-1) BM every 15 min during part A of the LIST (38.0 ± 5.5 g CHO h(-1) in the CHO trial). Intermittent endurance capacity was increased by 21.1% during part B when the CHO gel was ingested (4.6 ± 2.0 vs. 3.8 ± 2.4 min, P games players during a simulated team games protocol.

    2017-01-01

    Background Adolescents increasingly use the Internet for communication, education, entertainment, and other purposes in varying degrees. Given their vulnerable age, they may be prone to Internet addiction. Objective Our aim was to identify possible differences in the purpose of Internet use among adolescents with respect to age subgroup, country of residence, and gender and the distribution of Internet addiction across age subgroups. Another aim was to determine if there is a correlation between the purpose of Internet use and age and if this interaction influences the level of addiction to the Internet. Methods The study included a simple random sample of 1078 adolescents—534 boys and 525 girls—aged 11-18 years attending elementary and grammar schools in Croatia, Finland, and Poland. Adolescents were asked to complete an anonymous questionnaire and provide data on age, gender, country of residence, and purpose of Internet use (ie, school/work or entertainment). Collected data were analyzed with the chi-square test for correlations. Results Adolescents mostly used the Internet for entertainment (905/1078, 84.00%). More female than male adolescents used it for school/work (105/525, 20.0% vs 64/534, 12.0%, respectively). Internet for the purpose of school/work was mostly used by Polish adolescents (71/296, 24.0%), followed by Croatian (78/486, 16.0%) and Finnish (24/296, 8.0%) adolescents. The level of Internet addiction was the highest among the 15-16-year-old age subgroup and was lowest in the 11-12-year-old age subgroup. There was a weak but positive correlation between Internet addiction and age subgroup (P=.004). Male adolescents mostly contributed to the correlation between the age subgroup and level of addiction to the Internet (P=.001). Conclusions Adolescents aged 15-16 years, especially male adolescents, are the most prone to the development of Internet addiction, whereas adolescents aged 11-12 years show the lowest level of Internet addiction.

    In 2013, an estimated 2.1 million adolescents (age 10-19 years) were living with HIV globally. The extent to which health facilities provide appropriate treatment and care was unknown. To support understanding of service availability in 2014, Paediatric-Adolescent Treatment Africa (PATA), a non-governmental organisation (NGO) supporting a network of health facilities across sub-Saharan Africa, undertook a facility-level situational analysis of adolescent HIV treatment and care services in 23 countries. Two hundred and eighteen facilities, responsible for an estimated 80,072 HIV-infected adolescents in care, were surveyed. Sixty per cent of the sample were from PATA's network, with the remaining gathered via local NGO partners and snowball sampling. Data were analysed using descriptive statistics and coding to describe central tendencies and identify themes. Respondents represented three subregions: West and Central Africa ( n  = 59; 27%), East Africa ( n  = 77, 35%) and southern Africa ( n  = 82, 38%). Half (50%) of the facilities were in urban areas, 17% peri-urban and 33% rural settings. Insufficient data disaggregation and outcomes monitoring were critical issues. A quarter of facilities did not have a working definition of adolescence. Facilities reported non-adherence as their key challenge in adolescent service provision, but had insufficient protocols for determining and managing poor adherence and loss to follow-up. Adherence counselling focused on implications of non-adherence rather than its drivers. Facilities recommended peer support as an effective adherence and retention intervention, yet not all offered these services. Almost two-thirds reported attending to adolescents with adults and/or children, and half had no transitioning protocols. Of those with transitioning protocols, 21% moved pregnant adolescents into adult services earlier than their peers. There was limited sexual and reproductive health integration, with 63% of facilities

    There is only scarce number of studies available describing the lifestyle of adolescents living in Arab countries. Hence, we described physical activity (PA) and sedentary behaviors patterns among Kuwaiti adolescents and the associations with parental education. Cross-sectional data from 435 adolescents (201 boys and 234 girls) were collected from the Study of Health and Activity among Adolescents in Kuwait conducted between 2012 and 2013. Outcome variables included PA (ActiGraph GT1M accelerometers) and sedentary behaviors. Exposure variable was parental education. Descriptive and multiple logistic regression analyses were used to examine the association between parental education and outcome variables. Total sedentary time (minutes per day) was higher in girls [568.2 (111.6)] than in boys [500.0 (102.0)], whereas boys accumulated more minutes in light, moderate, and vigorous PA (all Ps ≤ .001). In total, 3.4% of adolescents spent ≥60 minutes per day of moderate to vigorous PA (by accelerometry), while only 21% met the screen time guidelines. Low/medium maternal education was associated with a higher odds of exceeding screen time guidelines (odds ratio = 2.09; 95% confidence interval, 1.09-4.02). Most Kuwaiti adolescents in this sample were physically inactive and exceeded screen time guidelines. Objective PA was not socially patterned, yet an inverse association between maternal education and screen time behaviors was found.

    2011-11-01

    This study compared the communication of two older male adolescents (aged 17 and 19 years) with each other (peer interaction) and with a teacher (non-peer interaction) in three different types of activity (casual conversation, providing/listening to a recount and collaborative problem-solving). Conversation analysis, selected analyses from the perspective of systemic functional linguistics and social psychology (communication accommodation theory) were applied in data analysis. Peer interaction showed fewer questions, fewer challenging moves and the absence of divergent accommodation strategies. In the non-peer interaction, the teacher's higher number of turns, questions and interruptions appeared to influence the opportunity for adolescent contribution to the interactions. Some aspects of language use by each adolescent - mean turn length, use of one-word utterances and sarcasm - were consistent across communication partner and activity. The methodology is suggested to provide a suitable procedure for use in similar research with older adolescents who have traumatic brain injury.

    Full Text Available Background: Perceived body image is an important potential predictor of nutritional status. Body image misconception during adolescence is unexplored field in Indian girls. Objectives: To study the consciousness of adolescent girls about their body image. Materials and Methods: This multistage observational study was conducted on 586 adolescent girls of age 10-19 years in Lucknow district (151 from rural, 150 from slum, and 286 from urban area of Uttar Pradesh, India. Information on desired and actual body size was collected with the help of predesigned questionnaire. Results: 20.5% of studied girls show aspiration to become thin, who already perceived their body image as too thin. 73.4% adolescent girls were satisfied with their body image, while 26.6% were dissatisfied. The dissatisfaction was higher among girls of urban (30.2% and slum (40.0% areas in comparison to rural (22.5% area. Percentage of satisfied girls was less in the 13-15 years (69.9% age groups in comparison to 10-12 years (76.5% and 16-19 years (76.4%. Among girls satisfied with their body image, 32.8% girls were found underweight, and 38.4% were stunted. Underweight girls (42.1% and stunted girls (64.9% were higher in number within satisfied girls of slum area. Among all of these adolescent girls, 32.8% of girls had overestimated their weight, while only 4.9% of girls had underestimated their weight. Conclusions: This study concludes that desire to become thin is higher in adolescent girls, even in those who already perceived their body image as too thin.

    This meta-analysis evaluated the effects of the expressive writing intervention (EW; Pennebaker & Beall, 1986) among adolescents. Twenty-one independent studies that assessed the efficacy of expressive writing on youth samples aged 10-18 ears were collected and analyzed. Results indicated an overall mean g-effect size that was positive in direction but relatively small (0.127), as well as significant g-effect sizes ranging from 0.107 to 0.246 for the outcome domains of Emotional Distress, Problem Behavior, Social Adjustment, and School Participation. Few significant effects were found within specific outcome domains for putative moderator variables that included characteristics of the participants, intervention instructions, or research design. Studies involving adolescents with high levels of emotional problems at baseline reported larger effects on school performance. Studies that implemented a higher dosage intervention (i.e., greater number and, to some extent, greater spacing of sessions) reported larger effects on somatic complaints. Overall, the findings suggest that expressive writing tends to produce small yet significant improvements on adolescents' well-being. The findings highlight the importance of modifying the traditional expressive writing protocol to enhance its efficacy and reduce potential detrimental effects. At this stage of research the evidence on expressive writing as a viable intervention for adolescents is promising but not decisive. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Studies suggest marijuana impacts gray and white matter neural tissue development, however few prospective studies have determined the relationship between cortical thickness and cannabis use spanning adolescence to young adulthood. This study aimed to understand how heavy marijuana use influences cortical thickness trajectories across adolescence. Subjects were adolescents with heavy marijuana use and concomitant alcohol use (MJ+ALC, n=30) and controls (CON, n=38) with limited substance use histories. Participants underwent magnetic resonance imaging and comprehensive substance use assessment at three independent time points. Repeated measures analysis of covariance was used to look at main effects of group, time, and Group × Time interactions on cortical thickness. MJ+ALC showed thicker cortical estimates across the brain (23 regions), particularly in frontal and parietal lobes (psadolescence and into young adulthood may be associated with altered neural tissue development and interference with neuromaturation that can have neurobehavioral consequences. Continued follow-up of adolescent marijuana users will help understand ongoing neural changes that are associated with development of problematic use into adulthood, as well as potential for neural recovery with cessation of use.

    The Global Early Adolescent Study (GEAS) was launched in 2014 with the primary goal of understanding the factors in early adolescence that predispose young people to subsequent sexual risks, and conversely, those that promote healthy sexuality across different cultural contexts. The present article describes the methodology that was used for the first phase of GEAS, which consisted of conducting qualitative research to understand the gendered transitions into adolescence and the role that gender norms play within the key relationships of adolescents. Researchers from each of the sites that had completed data collection were also elicited for their feedback on the key strengths, challenges, and lessons learned from conducting research among 11- to 14-year-old adolescents. The purpose of this article is to present the description of each of the methods that were used in GEAS, as well as the researchers' perspectives of using the methods among early adolescents in their sites. The GEAS is being implemented through a collaboration of university and nongovernmental institutions from 15 cities: Assiut (Egypt) Baltimore (U.S.), Blantyre (Malawi), Cape Town (South Africa), Cochabomba (Bolivia), Cuenca (Ecuador), Edinburgh (Scotland), Ghent (Belgium), Hanoi (Vietnam), Ile-Ife (Nigeria), Kinshasa (DRC), Nairobi (Kenya), New Delhi (India), Ouagadougou (Burkina Faso), and Shanghai (China). Approximately 30 in-depth interviews among adolescents and 30 in-depth interviews with their parent/guardian were conducted at each site, with adults and adolescents interviewed separately. To build trust and increase engagement among the adolescent participants, we used two different visual research methods: (1) timeline exercise which was small group based and (2) the Venn diagram exercise which was conducted individually and used at the start of the in-depth interview. The visual aspects of both the timeline and the Venn diagrams not only helped to produce data for the purposes of the

    To investigate sleep EEG changes in adolescents across 7 nights of sleep restriction to 5 h time in bed [TIB]) and 3 recovery nights of 9 h TIB. A parallel-group design, quasi-laboratory study was conducted in a boarding school. Fifty-five healthy adolescents (25 males, age = 15-19 y) who reported habitual TIBs of approximately 6 h on week nights (group average) but extended their sleep on weekends were randomly assigned to Sleep Restriction (SR) or Control groups. Participants underwent a 2-week protocol comprising 3 baseline nights (TIB = 9 h), 7 nights of sleep opportunity manipulation (TIB = 5 h for the SR and 9 h for the Control group), and 3 nights of recovery sleep (TIB = 9 h). Polysomnography was obtained on two baseline, three manipulation, and two recovery nights. Across the sleep restriction nights, total SWS duration was preserved relative to the 9 h baseline sleep opportunity, while other sleep stages were reduced. Considering only the first 5 h of sleep opportunity, SR participants had reduced N1 duration and wake after sleep onset (WASO), and increased total sleep time (TST), rapid eye movement (REM) sleep, and slow wave sleep (SWS) relative to baseline. Total REM sleep, N2, and TST duration remained above baseline levels by the third recovery sleep episode. In spite of preservation of SWS duration over multiple nights of sleep restriction, adolescents accustomed to curtailing nocturnal sleep on school day nights evidence residual effects on sleep macro-structure, even after three nights of recovery sleep. Older teenagers may not be as resilient to successive nights of sleep restriction as is commonly believed. © 2016 Associated Professional Sleep Societies, LLC.

    Full Text Available Background: Management of poor-responding patients is still major challenge in assisted reproductive techniques (ART. Delayed-start GnRH antagonist protocol is recommended to these patients, but little is known in this regards. Objective: The goal of this study was assessment of delayed-start GnRH antagonist protocol in poor responders, and in vitro fertilization (IVF outcomes. Materials and Methods: This randomized clinical trial included sixty infertile women with Bologna criteria for ovarian poor responders who were candidate for IVF. In case group (n=30, delayed-start GnRH antagonist protocol administered estrogen priming followed by early follicular-phase GnRH antagonist treatment for 7 days before ovarian stimulation with gonadotropin. Control group (n=30 treated with estrogen priming antagonist protocol. Finally, endometrial thickness, the rates of oocytes maturation, , embryo formation, and pregnancy were compared between two groups. Results: Rates of implantation, chemical, clinical, and ongoing pregnancy in delayed-start cycles were higher although was not statistically significant. Endometrial thickness was significantly higher in case group. There were no statistically significant differences in the rates of oocyte maturation, embryo formation, and IVF outcomes between two groups. Conclusion: There is no significant difference between delayed-start GnRH antagonist protocol versus GnRH antagonist protocol.

    Full Text Available Introduction: The swimmer is a high level athlete, with long limbs, and whose musculoskeletal components are important in sporting success. However, the fat component is paradoxical because of its relationship with the buoyancy and displacement of the body in the water. The aim of this study is to describe the anthropometric profile of adolescent competition swimmers.Material and methods: A total of 17 adolescent swimmers were evaluated, 10 boys (13.2 ±1.32 years and 7 girls (15±1.83 years. A qualified anthropometrist took anthropometric measures according to the protocol of the Society for the Advancement of Kinanthropometry (ISAK, with approved materials according to the methodology of Marfell-Jones et al, 2003. Body composition was calculated according to the consensus of Kinanthropometry and somatotype with Heath-Carter´s method.Results: Of all the variables studied (weight, height, folds, circumferences, diameters and lengths, significant differences were found (P<.05 between the sexes in height, arm span, skinfolds (triceps, subscapular, crestailiaca, ileo-spinal, abdominal, thigh, leg, sum of skinfolds, biacromial-bi-iliac index, bone body mass, muscle and fat, ectomorphy, and endomorphy.Conclusions: There are significant anthropometric differences between genders in adolescent swimmers (P<.05. Such differences, resulting in the development of both sexes, might be highly related to athletic performance of young athletes.

    There is a significant link between insecure attachment and the development of psychopathology in adolescence. We investigated the relationship between adolescent attachment styles and the development of emotional and behavioral problems among adolescents in Kenya. We also examined the modifying influence of socio-economic-status (SES). One hundred and thirty-seven adolescents who were attending two schools participated in the study. One school (low SES school) catered for children from predominantly low-income households, while the second school (middle SES school) catered for children from predominantly middle-income households. The data were collected using three instruments: researcher designed questionnaire to obtain socio-demographic information, the Strength and Difficulties Questionnaire (SDQ) that is designed to assess symptoms of disorder, and the Vulnerable Attachment Scale Questionnaire (VASQ) that is designed to measure attachment style. Adolescents from the low SES school had higher vulnerable attachment scores than those from the middle SES school ( t (135) = - 2.5, P  =  0.02 ). Male students had higher vulnerable attachment scores than females ( P  =  0.03 ). Adolescents who had experienced adversity in childhood had higher vulnerable attachment scores than those who had not ( P  attachment insecurity and emotional and behavioral problems with participants who had higher emotional symptoms (r = 0.47, P  attachment insecurity than those with lower scores. This study supports the notion that attachment insecurity increases the adolescents' susceptibility to develop psychological problems.

    The Wireless Sensor Network (WSN) is composed of a large number of sensor nodes with limited computation communication, and battery facilities. One of the common applications of this network is environment monitoring through sensing motion, measuring temperature, humidity and radiation. One of the basic activities in WSN is data gathering which represents a great challenge. Many routing protocols are proposed for that network to collect and aggregate the data. The most popular ones are hierarchy and data centric routing protocols. The main goal of this study is to identify the most preferable routing protocol, to be used in each mobility model. This paper studies the performance of LEACH (Low Energy Adaptive Clustering Hierarchy) from hierarchy routing protocol and direct diffusion from data centric routing protocol which is not clarified until now. Moreover, a comparison between LEACH and direct diffusion protocol using NS2 simulator will be made, and an analysis of these protocols will be conducted. The comparison includes packet delivery ratio, throughput, average energy ratio, average delay, network lifetime, and routing overhead. The performance is evaluated by varying the number of sensor nodes under three mobility models Reference Point Group Mobility Model (RPGM), Manhattan and random waypoint mobility model. Simulation results show that LEACH routing protocol has a good performance in RPGM and Manhattan than random waypoint mobility model. Direct diffusion has a good performance in random waypoint mobility model than in RPGM and Manhattan mobility model

    This study examined the prevalence and correlates of suicidal ideation and behaviour (SI/B) among adolescents receiving bariatric surgery. Charts of 206 adolescents receiving bariatric surgery were reviewed. Cases with SI/B (current/lifetime reported at baseline or event occurring in the programme n = 31, 15%) were case matched on gender, age and surgery type to 31 adolescents reporting current or past psychiatric treatment and 31 adolescents denying lifetime SI/B or psychiatric treatment. Before surgery, adolescents with SI/B reported significantly lower total levels of health-related quality of life (p = 0.01) and greater depressive symptoms (p = 0.004) in comparison with candidates who never received psychiatric treatment. No significant differences were found between groups for the change in depressive symptoms or body mass index following surgery. As in studies of adults, a notable subset of adolescents receiving bariatric surgery indicated pre-operative or post-operative SI/B. It is critical that clinicians evaluate and monitor adolescent patients undergoing bariatric surgery for risk of SI/B. Copyright © 2015 John Wiley & Sons, Ltd and Eating Disorders Association.

Cases with SI/B (current/lifetime reported at baseline or event occurring in the program n= 31, 15%) were case-matched on gender, age, and surgery type to 31 adolescents reporting current or past psychiatric treatment, and 31 adolescents denying lifetime SI/B or psychiatric treatment. Results Before surgery, adolescents with SI/B reported significantly lower total levels of health-related quality of life (p=0.01) and greater depressive symptoms (p=0.004) in comparison to candidates who never received psychiatric treatment. No significant differences were found between groups for the change in depressive symptoms or body mass index following surgery. Conclusions As in studies of adults, a notable subset of adolescents receiving bariatric surgery indicated pre- or post-operative SI/B. It is critical that clinicians evaluate and monitor adolescent patients undergoing bariatric surgery for risk of SI/B. PMID:26377705

    Given the increasing prevalence of obesity among Iranian adolescents and the role of consumption of unhealthy snacks in this issue, interventions that focus on factors influencing food choice are needed. This study was designed to delineate factors associated with unhealthy snack use among female Iranian adolescents. The theory of Planned Behavior served as the framework of the study. Qualitative data were collected via nine focus group discussions in two middle schools (6(th) to 8(th) grades) in a socio-economically diverse district in the city of Tehran in spring 2008. The study sample included 90 female adolescents aged 12-15 years. The sampling strategy was purposive method. Data analyzed using the "framework" method. Major factors identified by the respondents were taste, peer pressure, parental influence, easy access to unhealthy snacks, limited availability of healthy snacks, appeal of snacks, habit, high price of healthy snacks, and media advertisements. Nutritional value and healthiness was not one of the first priorities when buying snacks, as adolescents thought it was too early for them to worry about illness and adverse consequences of eating junk foods. For developing culturally sensitive evidence-based interventions that can motivate adolescents to choose healthy snacks, a broad range of factors should be taken into account.

    The transitional phase encompassing the physiological and psychological changes during our lifespan is termed as adolescence. Adolescents get mislead to substance use, violence related activities, dating relationships, unhealthy lifestyle. Minimal studies are conducted in India to identify the parenting factors that affect an adolescent's mind. The aim of our study was to explore the role of parenting and social surroundings on - adolescent's mental health and involvement in violence related activities. Cross sectional study design was adopted. Semi structured questionnaire was used. Data obtained was entered and analyzed using SPSS 15. Proportions were used to report the findings. Chi-square test was used to find associations between mental health issues, involvement in violence related activities and Interpersonal Relationship (IPR) Status. Multiple logistic regressions were done to identify independent predictors of mental health. A total of 1770 adolescents participated. Proportion of adolescents with good IPR with parents reported to be having a better mental health status and low involvement in violent related activities. Schools also displayed similar effects. Neighborhood, peers did not display any significant effect on adolescent's mental health. Most significant predictor for adolescent mental health was IPR with parents and at school. The study highlights the need of a cordial environment at places which does influence the adolescent's mental health. Interventions enhancing the relationship status of adolescents with parents, at school must be carried out to observe the change in adolescent behavior.

    Full Text Available Abstract Introduction: Inspiratory muscle training (IMT is a resource widely used in pediatrics. However, there is great variability in relation to the characteristics of the protocols used. Objective: To identify the main clinical conditions and IMT protocols used in the pediatric age group. Methods: Integrative review of the literature by searching on Pubmed, Scielo, PEDro and EMBASE databases using the following strategy: threshold OR inspiratory muscle training OR muscle endurance OR muscle resistance OR endurance training OR maximal inspiratory pressure AND respiratory muscle. We have selected clinical trials that performed IMT in children and adolescents (0 to 18 years old, with a clinical diagnosis, and published in English, Portuguese and Spanish. Results: 17 studies were included. From these, 11 underwent IMT in patients with some neuromuscular disorder, being Duchenne Muscular Dystrophy the most common. The selected articles included a total sample of 327 participants. As for the characteristics of the protocols, 7 performed strength training, 5 endurance and 5 strength and endurance. The training load ranged from 30 to 80% of maximal inspiratory pressure. Moreover, 8 studies performed IMT twice daily and the session duration and the training period varied between 10 and 30 minutes, and from 3 weeks to 24 months, respectively. Conclusion: The IMT was used more frequently in patients with some neuromuscular disorder. Although there is no consensus as to the characteristics of the protocols, the choice of the load should take into account the purpose of IMT and the disease severity.

    Adolescents at-risk for problem behaviors can have more difficulties in developing a firm sense of personal identity. Hence the purpose of this prospective longitudinal study was to scrutinize how externalizing problems in early adolescence impact identity development in middle to late adolescence. Participants were 443 (43.12% female) Dutch adolescents. Teachers rated their externalizing problem behaviors when participants were 11 or 12 years old and their identity formation was studied during five consecutive years (from 14 to 18 years of age). The sample was divided into four groups: boys and girls with a high versus a low-risk for externalizing problem behaviors. Participants completed a self-report measure of identity commitment, in-depth exploration, and reconsideration of commitment. Multi-group Latent Growth Curve and profile stability analyses were used to evaluate identity development across adolescence. Findings indicated that high-risk boys and girls reported a less structured identity, with lower levels of commitment and higher levels of reconsideration of commitment. Since externalizing problems behaviors and lack of a coherent sense of identity might reinforce each other, early intervention for high-risk adolescents might foster positive youth development.

    Background: Perceived body image is an important potential predictor of nutritional status. Body image misconception during adolescence is unexplored field in Indian girls. Objectives: To study the consciousness of adolescent girls about their body image. Materials and Methods: This multistage observational study was conducted on 586 adolescent girls of age 10–19 years in Lucknow district (151 from rural, 150 from slum, and 286 from urban area) of Uttar Pradesh, India. Information on desired and actual body size was collected with the help of predesigned questionnaire. Results: 20.5% of studied girls show aspiration to become thin, who already perceived their body image as too thin. 73.4% adolescent girls were satisfied with their body image, while 26.6% were dissatisfied. The dissatisfaction was higher among girls of urban (30.2%) and slum (40.0%) areas in comparison to rural (22.5%) area. Percentage of satisfied girls was less in the 13–15 years (69.9%) age groups in comparison to 10–12 years (76.5%) and 16–19 years (76.4%). Among girls satisfied with their body image, 32.8% girls were found underweight, and 38.4% were stunted. Underweight girls (42.1%) and stunted girls (64.9%) were higher in number within satisfied girls of slum area. Among all of these adolescent girls, 32.8% of girls had overestimated their weight, while only 4.9% of girls had underestimated their weight. Conclusions: This study concludes that desire to become thin is higher in adolescent girls, even in those who already perceived their body image as too thin. PMID:22090673

    The amount of bone accrued during adolescence is an important determinant of later osteoporosis risk. Little is known about the influence of dietary patterns (DPs) on the bone during adolescence and their potential long-term implications into adulthood. We examined the role of adolescent DPs on adolescent and young adult bone and change in DPs from adolescence to young adulthood. We recruited participants from the Saskatchewan Pediatric Bone Mineral Accrual Study (1991-2011). Data from 125 participants (53 females) for adolescent analysis (age 12.7 ± 2 years) and 115 participants (51 females) for adult analysis (age 28.2 ± 3 years) were included. Bone mineral content (BMC) and areal bone mineral density (aBMD) of total body (TB), femoral neck (FN) and lumbar spine (LS) were measured using dual-energy X-ray absorptiometry. Adolescent dietary intake data from multiple 24-h recalls were summarized into 25 food group intakes and were used in the principal component analysis to derive DPs during adolescence. Associations between adolescent DPs and adolescent or adult BMC/BMD were analyzed using multiple linear regression and multivariate analysis of covariance while adjusting for sex, age, the age of peak height velocity, height, weight, physical activity and total energy intake. Generalized estimating equations were used for tracking DPs. We derived five DPs including "Vegetarian-style", "Western-like", "High-fat, high-protein", "Mixed" and "Snack" DPs. The "Vegetarian-style" DP was a positive independent predictor of adolescent TBBMC, and adult TBBMC, TBaBMD (P adolescent TBaBMD and young adult TBBMC, TBaBMD, FNBMC and FNaBMD were 5%, 8.5%, 6%, 10.6% and 9% higher, respectively, in third quartile of "Vegetarian-style" DP compared to first quartile (P adolescence to adulthood. There were an upward trend in adherence to "Vegetarian-style" DP and an downward trend in adherence to "High-fat, high-protein" DP from adolescence to young adulthood (P adolescence

    The A&D TM-2430 ambulatory blood pressure (BP) monitor has been validated in adults but not in a young population. We sought to validate the device monitoring in children and adolescents, according to the British Hypertension Society (BHS) protocol. The A&D TM-2430 is an automated oscillometric upper-arm device for ambulatory BP monitoring. Nine consecutive measurements were taken in 61 children (mean age, 9.8 years; range, 5-15 years) according to the BHS criteria. Overseen by an independent supervisor, measurements were recorded by two observers blinded from each other's readings and from the device readings. The mean difference ± SD between the observers and device measurements was 0.73 ± 1.64 mmHg for systolic blood pressure (SBP) and -1.23 ± 1.65 mmHg for diastolic blood pressure (DBP), respectively, with an interobserver difference of 4 mmHg. The cumulative percentages of differences within 5, 10, and 15 mmHg were 89, 95, and 98% for SBP and 67, 88, and 98% for DBP. The device achieved a grade A rating for SBP and a B grade for DBP. The A&D TM-2430 upper-arm BP monitor has fulfilled the required BHS standards and can be recommended for measuring ambulatory BP in children and adolescent populations.

    Full Text Available Abstract Background Given the increase in overweight and obesity prevalence in adolescents in the last decade, effective prevention strategies for these conditions in adolescents are urgently needed. The PRALIMAP (Promotion de l'ALImentation et de l'Activité Physique trial aims to evaluate the effectiveness for these conditions of 3 health promotion strategies -- educational, screening and environmental -- applied singly or in combination in high schools over a 2-year intervention period. Methods PRALIMAP is a stratified 2 × 2 × 2 factorial cluster randomised controlled trial including 24 state high schools in Lorraine, northeastern France, in 2 waves: 8 schools in 2006 (wave 1 and 16 in 2007 (wave 2. Students entering the selected high schools in the 4 academic years from 2006 to 2009 are eligible for data collection. Interventional strategies are organized over 2 academic years. The follow-up consists of 3 visits: at the entry of grade 10 (T0, grade 11 (T1 and grade 12 (T2. At T0, 5,458 (85.7% adolescents participated. The educational strategy consists of nutritional lessons, working groups and a final party. The screening strategy consists in detecting overweight/obesity and eating disorders in adolescents and proposing, if necessary, an adapted care management program of 7 group educational sessions. The environmental strategy consists in improving dietary and physical activity offerings in high schools and facilities, especially catering. The main outcomes are body size evolution over time, nutritional behaviour and knowledge, health and quality of life. An evaluation process documents how each intervention strategy is implemented in the schools and estimates the dose of the intervention, allowing for a per protocol analysis after the main intention-to-treat analysis. Discussion PRALIMAP aims at improving the prevention and management of overweight and obesity in adolescents by translating current evidence into public health practice

    Laboratory social stress tests involving public speaking challenges are widely used for eliciting an acute stress response in older children, adolescents, and adults. Recently, a group protocol for a social stress test (the Trier Social Stress Test for Groups, TSST-G) was shown to be effective in adults and is dramatically less time-consuming and resource-intensive compared to the single-subject version of the task. The present study sought to test the feasibility and effectiveness of an adapted group public speaking task conducted with a racially diverse, urban sample of U.S. adolescents (N=191; 52.4% female) between the ages of 11 and 18 (M=14.4 years, SD=1.93). Analyses revealed that this Group Public Speaking Task for Adolescents (GPST-A) provoked a significant increase in cortisol production (on average, approximately 60% above baseline) and in self-reported negative affect, while at the same time avoiding excessive stress responses that would raise ethical concerns or provoke substantial participant attrition. Approximately 63.4% of participants exhibited an increase in cortisol levels in response to the task, with 59.2% of the total sample showing a 10% or greater increase from baseline. Results also suggested that groups of five adolescents might be ideal for achieving more uniform cortisol responses across various serial positions for speech delivery. Basal cortisol levels increased with age and participants belonging to U.S. national minorities tended to have either lower basal cortisol or diminished cortisol reactivity compared to non-Hispanic Whites. This protocol facilitates the recruitment of larger sample sizes compared to prior research and may show great utility in answering new questions about adolescent stress reactivity and development.

    The present study aimed to investigate the level of self-esteem among religious minority adolescents (Christians and Hindus) by making a comparison with their dominant counterparts (Muslims) in Pakistan. It was hypothesized that adolescents of religious minorities would have lower level of self-esteem than their dominant counterparts. In the present study 320 adolescents participated, in which 160 adolescents belonged to minority religious groups (i.e. 76 Christians and 84 Hindus) and 160 adolescents belonged to dominant religious group i.e. Muslims. To assess self-esteem of the participants, Rosenberg Self-Esteem Scale (Rosenberg in Society and the adolescent self image, Princeton University Press, Princeton, NJ, 1965) was used. One Way Analysis of Variance reveals that religious minority adolescents (Christians and Hindus) inclined to have lower self-esteem as compared to their dominant counterpart (Muslim adolescents).

    The media, mainly TV, play a significant social and cultural role and may affect the prevalence and incidence of eating disorders such as bulimia and anorexia nervosa. Their influence acts mainly by favoring a tall and thin body as the only fashionable for female adolescents: your social success depends primarily and totally by your physical appearance and you can, (and must), shape your body as you like better. Our research aims t analyze the attitude of adolescent people toward the TV and to investigate on: 1) time spent watching TV programs; 2) the influence of TV on the personal choices of goods to buy; 3) the ideal body images; 4) choice of TV programs. Sixty-seven healthy adolescents (36 F-31 M) were included in our study as controls together with 24 female adolescents with eating disorders (DCA) diagnosed according to the DSM-IV and EAT/26 criteria. Our results show a psychological dependence of DCA adolescents from the TV (longer period of time spent watching TV programs, buying attitudes more influenced by TV advertising). The thin and tall body image is preferred by the DCA girls as well as by the controls; however the body appearance and proportions have a predominant and utmost importance only for the eating disorder females. The masculine subjects instead have a preference for a female and masculine opulent body appearance. To prevent the observed increase in prevalence and incidence of eating disorders among adolescents, it is appropriate to control the messages, myths and false hood propagated by media, TV in particular.

    Population-based studies estimating prevalence's of white-coat, masked and sustained hypertension in non-European adolescents are needed, particularly in developing countries. Aiming to determine these estimates and, additionally identify factors associated to these conditions this study was conducted. Cross-sectional study with a representative sample of secondary school students from a Brazilian state capital. Office measurements were performed with validated semi-automatic devices. Home BP (blood pressure) monitoring protocol included two day-time and two evening-time measurements over 6 days. Adolescents' were classified as: normotensives (office and home BP coat hypertensives (office BP ≥95th percentile and home BP coat, masked and sustained hypertension. In a sample of 1024 adolescents, prevalence of white-coat, masked and sustained hypertension was 7.5%, 2.2% and 1.7%, respectively. Male sex was positively associated with white-coat hypertension (OR 2.68; 95%CI 1.58-4.54; p coat (OR 1.23; 95%CI 1.16-1.30; p coat hypertension, masked and sustained hypertension in a population of non-European adolescents assessed by home BP monitoring was 7.5%, 2.2% and 1.7% respectively. Male sex was positively associated with white-coat hypertension in these adolescents while BMI was positively associated with both white-coat and sustained hypertension.

    `The gradual reduction in the incidence of AIDS among men who have sex with men has not occurred in the youngest age group; on the contrary, it is growing. This paper examines the vulnerabilities of adolescent males at risk of HIV infection. This is a qualitative study conducted through interviews with HIV positive young men undergoing treatment, whose diagnosis was made during adolescence. The interviews were recorded and transcribed in full. They were analyzed by intensive reading, classified by issues, and interpreted from a hermeneutic-dialectic perspective in dialogue with the literature. We interviewed 16 young men whose diagnosis occurred between the ages of 11 and 19 and for all of them the method of HIV transmission was sexual; 12 of the men were homosexual and 4 were heterosexual. It was evident that vulnerable situations included disbelief in the possibility of contamination, subjection to sex, homophobia and commercial sexual exploitation. This study demonstrates the importance of the formulation of public policies on sexual and reproductive health, which include adolescents and young men. These policies should embody the perspective of masculinity in all its widest aspects, as well as actions in favor of sexual diversity.

    The aim of the current study was to examine sleep patterns and rates of insomnia in a population-based study of adolescents aged 16-19 years. Gender differences in sleep patterns and insomnia, as well as a comparison of insomnia rates according to DSM-IV, DSM-V and quantitative criteria for insomnia (Behav. Res. Ther., 41, 2003, 427), were explored. We used a large population-based study in Hordaland county in Norway, conducted in 2012. The sample included 10,220 adolescents aged 16-18 years (54% girls). Self-reported sleep measurements included bedtime, rise time, time in bed, sleep duration, sleep efficiency, sleep onset latency, wake after sleep onset, rate and frequency and duration of difficulties initiating and maintaining sleep and rate and frequency of tiredness and sleepiness. The adolescents reported short sleep duration on weekdays (mean 6:25 hours), resulting in a sleep deficiency of about 2 h. A majority of the adolescents (65%) reported sleep onset latency exceeding 30 min. Girls reported longer sleep onset latency and a higher rate of insomnia than boys, while boys reported later bedtimes and a larger weekday-weekend discrepancy on several sleep parameters. Insomnia prevalence rates ranged from a total prevalence of 23.8 (DSM-IV criteria), 18.5 (DSM-V criteria) and 13.6% (quantitative criteria for insomnia). We conclude that short sleep duration, long sleep onset latency and insomnia were prevalent in adolescents. This warrants attention as a public health concern in this age group. © 2013 European Sleep Research Society.

Terminological difficulties which overcoming represents a relevant scientific and practical task are discussed. Adolescent dating violence is treated as a specific phenomenon which should be distinguished from bullying, school violence, etc. The data characterizing frequency of violence in the teenage romantic relations are systematized; it is established that up to 2/3 teenagers in foreign countries have experience of adolescent dating violence either as offenders, or as victims, in structure of the discussed phenomenon into the forefront psychological violence acts. Biographic, individual and psychological and social and environmental predictors of adolescent dating violence are considered. Process of transformation of behavior within adolescent dating violence with transition to more mature, partner or marriage, to the relations is tracked. Special attention is paid to sexual differences in predisposition to commission of adolescent dating violence and also his influence on character of the subsequent "adult" relations.

    To measure the degree to which childhood and adolescent ratings of aggression, attention, and delinquency are related to adolescent substance use outcomes in youth diagnosed with attention-deficit/hyperactivity disorder (ADHD). Childhood externalizing disorders have been shown to predict adolescent maladaptive substance use, but few studies have examined the differential predictive utility of two distinct dimensions of externalizing behavior: aggression and delinquency. Ninety-seven clinically referred children with ADHD initially took part in this research protocol when they were on average 9.05 years of age, and were seen again on average 9.30 years later. Participants' parents were administered the Child Behavior Checklist (CBCL) at baseline and follow-up, and youth completed the Youth Self Report (YSR) in adolescence. At follow-up, substance use severity and diagnosis were assessed using semi-structured psychiatric interviews administered separately to parents and adolescents. Linear and binary logistic regressions were used to determine the association of CBCL- and YSR-rated attention problems, aggression, and delinquency to adolescent substance use. Childhood and adolescent delinquency, but not aggression, as rated by parents and youths, predicted adolescent substance use disorders and substance use severity (all p delinquency and aggression with adolescent substance use, ratings of attention problems in childhood and adolescence were negatively associated with substance use outcome. Children with ADHD who exhibit high rates of delinquency are at risk for later substance use and may require targeted prevention, intervention, and follow-up services.

    Data about the predictors of smoking among adolescents in Greece are sparse. We tried to identify factors associated with current cigarette smoking among in-school adolescents in Greece in the context of GYTS study. A secondary analysis of data from a questionnaire study using the Global Youth Tobacco Survey methodology was conducted to identify factors associated with smoking among adolescents in Greece. Data were collected in 2004-2005. The outcome variable was cigarette smoking within the past 30 days preceding the survey while independent variables included age, gender, parental educational status, parental smoking, perception of harmfulness of smoking, and the amount of pocket money at the adolescent's disposal. 6141 adolescents (51.5% males and 48.5% females) participated in the study. In multivariate analysis, cigarette smoking was associated with male gender (OR: 1.62; 95% CI: 1, 08-3.08), parental smoking (OR: 2.59; 95% CI: 1.45-5.89), and having pocket money > or = 16 Euros (OR: 2.64; 95% CI: 1.19-5.98). Male gender, parental smoking, and having pocket-money > or = 16 Euros were independently associated with current smoking among Greek students. These findings could be taken into account in order to formulate a comprehensive anti-smoking strategy in Greece.

    Smoking represents a public health problem, one which begins during adolescence. The main objective of this study was to analyze the association between smoking and parental and school factors. The study sample consisted of the students from the 20 secondary schools in the region of Osona, Barcelona, Spain. A self-report questionnaire was used to obtain information on the following variables: smoking habit, age of initiation, frequency, type of school (state school or private-subsidized), sex, age, persons living in the home, town, whether the student had lunch at school, whether the student often had lunch or dinner alone at home. A total of 2280 students participated in the study (91%). Mean age was 15.5 years. Of the participants, 20% said they were smokers; 5%, ex-smokers; 34% had tried smoking at least once, and 41% had never smoked. Factors significantly associated with smoking in the multivariate analysis were age, rural town, state school, single parent family, eating alone, and not lunching at school. Smoking prevalence is high among adolescents in our society and there is no gender difference. Our results show that family structure and dynamics can influence smoking in adolescents. Smoking is less prevalent among adolescents who have lunch at school.

    Adolescents with chronic pain often report inattention and poor memory. There has been little research on cognitive function in this population. The goal of this preliminary pilot study was to examine differences in cognitive function between adolescents with chronic pain to pain-free adolescents. All participants completed baseline assessments of pain, school absences, depression, anxiety, and sleep habits. Standardized neurocognitive tests were used to examine cognitive function with a focus on working memory and attention. Recruitment from the chronic pain clinic resulted in a female sample of 13 individuals (largely reflective of the clinical population). Pain-free age-matched and sex-matched individuals (n=12) were therefore also recruited as controls. Individuals with chronic pain had significantly lower working memory scores than controls. Differences were found between groups on the most difficult selective attention task and not on tests of sustained attention, divided attention, or attentional switching. In a stepwise regression with baseline characteristics entered in the first step, pain accounted for approximately 15% of the variance in working memory and medication score counted for 49% of the variance. This pilot study is the first study to examine differences in working memory and attention between participants with chronic pain and pain-free adolescents. Our findings suggest that chronic pain may negatively affect adolescents' working memory function and highlights the risk for cognitive difficulties and problems with educational progression in addition to negative health and social effects associated with chronic pain. The study provides a starting point for more research and has the potential to direct better identification and treatment of these cognitive deficits.

    This study investigated the potential accident-proneness of adolescents with attention deficit hyperactivity disorder (ADHD) in a hazardous road-crossing environment. An immersive virtual reality traffic gap-choice task was used to determine whether ADHD adolescents show more unsafe road-crossing behavior than controls. Participants (ages 13 to 17) were identified with (n = 24) or without (n = 24) ADHD according to a standardized protocol (Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version and Conners' Scales), with equal number of boys (n = 12) and girls (n = 12) in each group. ADHD adolescents did not take stimulant medication on the day of testing. Participants with ADHD had a lower margin of safety, walked slower, underutilized the available gap in incoming traffic, showed greater variability in road-crossing behavior, and evidenced twice as many collisions as compared to controls. No sex differences were found. Virtual reality may help identify and educate those at higher risk of being involved in dangerous traffic situations.

    The Star Excursion Balance Test (SEBT) is commonly used to evaluate dynamic equilibrium. The Y Balance Test (Y-BT) is a shortened version of the SEBT where a Y- Balance Kit is commonly used. To date, research concerning the protocol and reliability of the SEBT and Y-BT has been conducted only for adults. The aim of the study was to assess the protocol (the necessary number of trials to stabilize the results) and reliability of the Y-BT in adolescent athletes. One-way repeated-measures analysis of variance (ANOVA) and reliability study. The sample of 38 athletes (mean age: 15.6 years) was selected from a football club. A Y-Balance test kit was applied for the evaluation of dynamic balance. The analysis used the values normalized to the relative length of the lower limbs. After six attempts, three consecutive ones achieved stability for all directions and both extremities (p > 0.05). The intraclass correlation coefficient (ICC 3,1 ), standard error of measurement and minimal detectable change values for the three attempts ranged from 0.57 to 0.82, from 3 to less than 6% and from 7.68 to 13.7%, respectively. In the study of adolescent dynamic equilibrium using the Y-BT, it is recommended to perform nine attempts (including six trial attempts and three measurements). In order to increase reliability it is recommended that the average of the three measured attempts is analysed. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Background Family-based intervention is essential for adolescents with behavioral problems. However, limited data are available on the relationship between family-based factors and adolescent internet addiction (AIA). We aimed to examine this relationship using a representative sample of Shanghai adolescents. Methods In October 2007, a total of 5122 adolescents were investigated from 16 high schools via stratified-random sampling in Shanghai. Self-reported and anonymous questionnaires were used to assess parent-adolescent interaction and family environments. AIA was assessed by DRM-52 Scale, developed from Young’s Internet-addiction Scale, using seven subscales to evaluate psychological symptoms of AIA. Results Adjusting for adolescents’ ages, genders, socio-economic status, school performances and levels of the consumption expenditure, strong parental disapproval of internet-use was associated with AIA (vs. parental approval, OR = 2.20, 95% CI: 1.24-3.91). Worse mother-adolescent relationships were more significantly associated with AIA (OR = 3.79, 95% CI: 2.22-6.48) than worse father-adolescent relationships (OR = 1.76, 95% CI: 1.10-2.80). Marital status of “married-but-separated” and family structure of “left-behind adolescents” were associated with symptoms of some subscales. When having high monthly allowance, resident students tended to develop AIA but commuter students did not. Family social-economic status was not associated with the development of AIA. Conclusions The quality of parent-adolescent relationship/communication was closely associated with the development of AIA, and maternal factors were more significantly associated with development of AIA than paternal factors. Family social-economic status moderated adolescent internet-use levels but not the development of AIA. PMID:24731648

    The study aimed to investigate potential adolescent and parental psychosocial risk and protective factors for psychological distress among adolescents and, in addition, to examine potential gender and age differences in the effects of risk factors on adolescent psychological distress. Data were collected among 8,984 Norwegian adolescents (13-19 years) and their parents in the Nord-Trøndelag Health Study (HUNT). The outcome measure was psychological distress (SCL-5). Bivariate regression analysis with generalized estimating equation (GEE) model showed that all parental self-reported variables (mental distress, substance use, social network, economic problems, unemployment and family structure) and adolescents' self-reported variables (leisure activities, social support from friends, school-related problems and substance use) were significantly associated with psychological distress among adolescents. Results revealed that in a multiple regression analysis with a GEE model, adolescent psychosocial variables, specifically academic-related problems and being bullied at school, emerged as the strongest predictors of psychological distress among adolescents after controlling for age, gender, and all parental and adolescent variables. The following psychosocial risk factors were significantly more important for girl's psychological distress compared to boys: problems with academic achievement, conduct problems in school, frequency of being drunk, smoking, dissatisfaction in school, living alone and seen parents being drunk. Academic achievement and being bullied at school were the psychosocial factors most strongly associated with psychological distress among adolescents. Parental factors had an indirect effect on adolescent psychological distress, through adolescents' psychosocial factors.

    Inadequate physical activity has adverse health consequences among adolescents. Mental health problem can be developed by lack of physical activity however it is controversial. The current study aimed to examine the association between level of physical activity with depression, anxiety and stress symptoms among adolescents. A representative sample of 1747 adolescents (13-14 years) was randomly selected from 6 schools in a south part of Malaysia. Respondents were asked to fill consent form, and questionnaires including Depression Anxiety and Stress Scale-21 and Physical Activity Questionnaire for Adolescents. Majority of respondents (71.9%) was Malay and more than half of the adolescents had low physical activity. About 40% had depression symptoms, followed by anxiety symptoms (65.9%) and stress symptoms (38.5%). Level of physical activity was significantly associated with gender, anxiety and stress (P<0.001). There were no associations with race, religion and depression symptom. This study provides some evidence among school-going adolescents related to anxiety and stress symptoms and low physical activities. Further studies are needed to show the protection effects of higher physical activity for depression, anxiety and stress symptoms in adolescents.

    Sleep disturbances are common among adolescents, but there are no brief interventions to treat them. The objective of this study was to evaluate the effectiveness of a brief semistructured, individually delivered sleep intervention to ameliorate adolescents' sleeping difficulties and lengthen sleep duration. All students aged 16-18 years in a high school were screened for sleeping difficulties and 36 students with the highest sleep problem scores were invited to the intervention. Postintervention improvements were observed on self-reported and actiwatch-registered sleep duration, self-reported sleep quality and sleep latency, perceived stress and anxiety (all p values sleep efficiency and sleep latency did not change (p > 0.05). A brief individual sleep intervention can be effective in lengthening sleep duration and improving subjective sleep quality and well-being among adolescents.

    Full Text Available Bullying in school, being a serious threat to physical and emotional health of children and adolescents all over the world, represents an important public health issue. In Italy, since 2007, the Italian Ministry of Education promotes activities to fight against and to prevent bullying in schools of all levels and, at the same time, also Health Authorities are trying to implement effective social-health responses. However, to date, the lack of consistent data, from national to local level, that could help in describing the problem in a proper manner, does not allow a systematic bullying surveillance and so also measuring the effectiveness of the public health strategy that could be implemented. The Bias pilot study’s aim is to evaluate the prevalence of bullying in a sample of schools in the city of Palermo, the largest in Sicily, and to investigate its characteristics in relation to different types of school. Finally, the Bias study aim to evaluate the feasibility of alternative methods for the detection of the prevalence of bullying phenomenon in schools. Here we present the research protocol and the questionnaires that will be used.

    Lack of depression literacy is associated with low help-seeking behaviors for mental health care in adolescents. As parents generally determine adolescents' health care, ensuring parents can recognize depressive symptoms is crucial. The current study explored depression literacy among Korean American parents of adolescents ages 12 to 19 using a qualitative descriptive design. Semantic content analysis was performed using data from three focus group interviews conducted in 2015 with Korean American parents (10 mothers, four fathers) of adolescents. Participants lacked knowledge about the biological causes and medicinal treatment of depression. Most believed that depression cannot be fully treated, relapses occur easily, and medication is taken indefinitely. Gender influenced perceptions of symptoms. Parents often overlooked children's depressive symptoms until schools alerted them. Nursing interventions should educate parents about the biological causes of depression, strategies for addressing adolescents' symptoms, community-based professional resources, and success stories about depression treatment.

    More adolescents report pain now than previously. In Norway, episodic pain problems have been reported by 60% of children and adolescents aged 8-18 years, with 21% reporting duration of pain of more than 3 months. Since adolescents spend much time at school, the attitude and behaviour of teachers play important roles regarding the experience of pain felt by adolescents in everyday life. Yet research on how teachers perceive the pain experienced by adolescents in a school setting is limited. We therefore seek to gain insight to teachers' classroom experiences with (1) adolescent's self-reported pain symptoms; (2) adolescents management of their pain and (3) how to help adolescents manage their pain. Teachers in 5 junior high schools in Norway representing municipalities in 3 rural areas and 2 cities. A qualitative study with an explorative design comprising 5 focus group interviews. Each group consisted of 3-8 junior high school teachers. A semistructured interview guide was used to cover the issues. The transcribed text was analysed with qualitative content analysis. 22 teachers participated (5 men, 17 women; age range 29-62 years) with teaching experience ranging from 3 to nearly 40 years. The main theme describing the experience of teachers with adolescents' pain in everyday life is that pain and management of pain is a social, physical and psychological interwoven phenomenon. Through empirical analyses, 3 subcategories emerged: (1) everyday pain--expressing strenuous life; (2) managing pain--escaping struggle and (3) strategies of teachers--support and normalisation. Teachers have a biopsychosocial understanding and approach to pain experienced by adolescents. This understanding influences the role of teachers as significant others in the lives of adolescents with regard to pain and management of their pain in a school setting.

    Studies of war-exposed children have not investigated a comprehensive array of resilience-promoting factors, nor representative samples of children and adolescents. A representative sample of N = 710 adolescents was randomly selected from communities recently exposed to war. All those who had experienced war trauma were administered questionnaires measuring war exposure, family violence, availability of leisure activities, school-related problems, interpersonal and peer problems, socialization, daily routine problems, displacement, availability of parental supervision and contact and medical needs as well as coping skills related to religious coping, denial, self-control, avoidance and problem solving. Mental health was measured by the Strengths and Difficulties Questionnaire (SDQ) and the Child-Revised Impact of Events Scale (CRIES). Resilient adolescents were defined as those who experienced war trauma, but did not manifest any symptoms on the SDQ or CRIES. Resilience was related to being male, using problem-solving techniques, having leisure activities, and having parents who spent time with their adolescents and who supported them with school work. Interventions designed for war-traumatized youth must build individual coping skills of children and adolescents, yet at the same time target parents and teachers in an integrated manner.

    In immigrant families, culture brokering (CB) refers to the ways in which children and adolescents serve as mediator between their family and aspects of the new culture. This study focused on the debate in the literature about whether CB implies "role reversal" in the family and "adultification" of the adolescent or whether CB is better understood as simply one of the many ways that immigrant children contribute to family functioning. Results indicated a mixed picture with respect to this debate. Greater amounts of adolescent CB were indeed related to higher adolescent reports of family conflict, but also to greater family adaptability. In addition, the amount of CB was unrelated to family satisfaction and family cohesion. Secondary questions centered on the relationship of CB to adolescent and parent demographic and acculturation variables. Here, CB was related to parent acculturation patterns but not those of adolescents. Implications for future research on the CB role are discussed. (c) 2007 APA, all rights reserved.

    This study intends to evaluate whether the belief that condoms are 100% effective in protecting against HIV infection is associated with sexual risk behaviours among youth. A cross-sectional study was performed in representative samples of high-school students in the Philippines, El Salvador and Peru. Participants completed a self-administered questionnaire. Students were asked about the risk of HIV transmission if one has sex using condoms. They were also asked to indicate whether they had ever had sexual relations and whether they used a condom in their first sexual relation. The sample was composed of 8994 students, aged 13-18. One out of seven adolescents believed condoms are 100% effective (safe-sex believers). Those adolescents were 82% more likely to have had sex than those without such belief, after adjusting for confounders (OR=1.82; 95% CI 1.51 to 2.21). On the contrary, no association was found between risk perception and condom use. Subgroup and sensitivity analyses produced similar results. This is, to the best of our knowledge, the first study conducted specifically to evaluate this phenomenon and that has used the same questionnaire and the same data collection protocol in three different developing countries from Asia, Central and South America. These results reasonably suggest that there could be an association between safe sex beliefs and sexual initiation. Longitudinal studies are needed to better understand this possible association as it could influence how to better promote sexual health. Published by the BMJ Publishing Group Limited.

    Over the past decade, nursing has identified the significance of self-esteem in maintaining wellness among adolescents. Low self-esteem has been linked to numerous adolescent risk behaviors such as smoking, drug use, and sexual activity. Adolescents engaging in these risk behaviors may have subsequent health problems, such as alcohol and drug addiction, as well as teen pregnancy. Present treatment modalities for low self-esteem have not been optimally effective. Nursing needs to examine adolescent self-esteem within the discipline of nursing and develop its own prevention and intervention strategies. Guided by the Roy Adaptation Model, our study used a descriptive, correlational design and examined the self-report of self-esteem on age group, gender, exercise participation, smoking, parental alcohol usage, depression, and anger in a nonclinical, community sample of adolescents aged 12-19.

    Full Text Available Little work has been conducted that examines the effects of positive environmental experiences on brain development to date. The aim of this study was to prospectively investigate the effects of positive (warm and supportive maternal behavior on structural brain development during adolescence, using longitudinal structural MRI. Participants were 188 (92 female adolescents, who were part of a longitudinal adolescent development study that involved mother–adolescent interactions and MRI scans at approximately 12 years old, and follow-up MRI scans approximately 4 years later. FreeSurfer software was used to estimate the volume of limbic-striatal regions (amygdala, hippocampus, caudate, putamen, pallidum, and nucleus accumbens and the thickness of prefrontal regions (anterior cingulate and orbitofrontal cortices across both time points. Higher frequency of positive maternal behavior during the interactions predicted attenuated volumetric growth in the right amygdala, and accelerated cortical thinning in the right anterior cingulate (males only and left and right orbitofrontal cortices, between baseline and follow up. These results have implications for understanding the biological mediators of risk and protective factors for mental disorders that have onset during adolescence.

    Parents of high school seniors with type 1 diabetes mellitus are faced with many concerns and fears as their adolescent prepares to assume primary disease management responsibility and leave the parental residence. The purpose of this study was to explore the relationship between parental separation anxiety and adolescent self-management and glycemic control. A second aim was to assess the relationship between adolescent self-management and glycemic control. Twenty-three families who had adolescents 16 to 18 years of age in or entering in their senior year of high school were recruited. Adolescents from higher income families reported better self-management skills than those from poorer families (r = 0.410, p = 0.05). Length of time since diabetes diagnosis was inversely related to glycemic control (r = 0.448, p = 0.02), indicating that adolescents who had the disease longer had poorer control. Parental separation anxiety was not related to adolescent self-management. Adolescent self-management was negatively related to glycemic control (r = -0.370, p = 0.08), suggesting that adolescents who demonstrated better self-management skills had improved glycemic control in comparison to adolescents who did not demonstrate effective self-management skills. Paternal, not maternal, separation anxiety demonstrated a significant relationship with glycemic control (r = 0.639, p < 0.001).

    Low self-worth during adolescence predicts a range of emotional and behavioural problems. As such, identifying potential sources of influence on self-worth is important. Aspects of the parent-child relationship are often associated with adolescent self-worth but to date it is unclear whether such associations may be attributable to familial confounding (e.g. genetic relatedness). We set out to clarify the nature of relationships between parental expressed affection and adolescent self-worth, and parent-child closeness and adolescent self-worth. We used data from the Twin and Offspring Study in Sweden, a children-of-twins sample comprising 909 adult twin pairs with adolescent children. Using these data we were able to apply structural equation models with which we could examine whether associations remained after accounting for genetic transmission. Results demonstrated that parent-child closeness and parental-expressed affection were both phenotypically associated with adolescent self-worth. Associations could not be attributed to genetic relatedness between parent and child. Parent-child closeness and parental affection are associated with adolescent self-worth above and beyond effects attributable to genetic relatedness. Data were cross-sectional, so the direction of effects cannot be confirmed but findings support the notion that positive parent-child relationships increase adolescent self-worth. © 2016 The Authors.

    Within the Self-Determination Theory (SDT) framework, the first major study aim was to investigate the SDT tenets in an obese adolescent population by examining the factor structure of the Behavioural Regulation in Exercise Questionnaire-2 (BREQ-2) and by investigating associations between physical activity (PA) and motivation in obese adolescents. The second aim was to study differences in motivation according to adolescents' educational level, since lower educated obese adolescent are a sub-risk group for lower PA levels among the obese adolescents. The third aim was to investigate whether attending a residential obesity treatment program could lead to an increase in autonomous motivation towards PA and to see if the treatment effect on motivation was different in low versus high educated youth. For the first study aim, the sample comprised 177 obese adolescents at the start of a 10-month multidisciplinary residential obesity treatment program (BMI = 35.9 ± 6.0 kg/m², 15.1 ± 1.5 years, 62% girls). A subsample of 65 adolescents (stratified by educational level) were divided into low (n = 34) versus high educated (n = 31) as part of the second and third study aim. Motivation was assessed using the BREQ-2 and PA using the Flemish Physical Activity Questionnaire. Exploratory factor analysis showed sufficient validations with the original factor for 17 out of 19 BREQ-2 items. Significant positive correlations were found between PA and the composite score of relative autonomy (r = 0.31, p intrinsic regulation (r = 0.38, p educated adolescents scored higher on the composite score of relative autonomy, introjected, identified and intrinsic regulation at the start of treatment (F = 3.68, p intrinsic regulation significantly increased during treatment for all adolescents (F = 6.65, p educated adolescents (F = 25.57, p motivation towards PA were related to higher PA levels. Adolescents had increases in both autonomous and controlled forms of motivation during treatment

    Major aetiologies of atherosclerotic cardiovascular diseases begin in childhood and atherosclerotic vascular abnormalities can be observed among children and adolescents. Adolescent cohort studies have important advantages because they can observe earlier changes in vascular structure and function. The purpose of the JS High School study (JSHS) is to identify biomarkers predicting or indicating early structural and functional vascular change in adolescents. The JSHS is a prospective cohort study of a Korean adolescent population. The target population of the JSHS was first-graders (aged 14 to17 years) at a high school of South Korea. Enrolment and baseline examinations were conducted in years 2007, 2010, 2011 and 2012. Among the total eligible population of 1115 students, 1071 (96.1%) participated in the study and completed all baseline examinations. Informed consent forms were obtained from each participant and his/her parent or guardian. Baseline examinations include: questionnaires on demographics, health behaviours, medical history, and depression symptoms; fasting blood analysis; anthropometric measurement; body impedance analysis; blood pressure measurement; radial artery tonometry; bone densitometry; pulmonary function tests; and carotid ultrasonography. Participants enrolled from 2007 through 2012 were re-examined after 30 months of follow-up, and those who enrolled in 2012 were re-examined after 24 months of follow-up.

    Recent genetic evidence suggests that the most important environmental influences on normal and pathologic development are those that are not shared by siblings in the same family. We sought to determine the relationship between differences in parenting styles and depressive symptoms and antisocial behavior in adolescence, and to compare the influence of these nonshared experiences with genetic influences. We studied 708 families with at least two same-sexed adolescent siblings who were monozygotic twins (93 families), dizygotic twins (99 families), ordinary siblings (95 families), full siblings in step families (181 families), half siblings in step families (110 families), and genetically unrelated siblings in step families (130 families). Data on parenting style were collected by questionnaire and by video recording of interaction between parents and children. Almost 60% of variance in adolescent antisocial behavior and 37% of variance in depressive symptoms could be accounted for by conflictual and negative parental behavior directed specifically at the adolescent. In contrast, when a parent directed harsh, aggressive, explosive, and inconsistent parenting toward the sibling, we found less psychopathologic outcome in the adolescent. Parenting behavior directed specifically at each child in the family is a major correlate of symptoms in adolescents. Furthermore, harsh parental behavior directed at a sibling may have protective effects for adolescents, a phenomenon we call the "siblin barricade."

    The purpose of this pilot study is to evaluate the feasibility of a cognitive-behavioural training program for adolescents with chronic pain irrespective of pain localisation. A secondary aim was to give an impression of the effect of the program on pain and quality of life. Eight adolescents (14-18 years) with chronic non-organic pain recruited from the general population (and their parents) participated in this pilot study. The intervention included five group meetings alternated with four telephone contacts (during the self-management weeks) over a period of 9 weeks. The training aimed to change pain behaviour through pain education, relaxation strategies, problem-solving techniques, assertiveness training, cognitive restructuring and by stimulating the adolescent's physical activity level. The training further addresses the social context of pain by inviting parents to attend two meetings for the parents only, and by asking the adolescents to bring a peer to one of the meetings. Adolescents and their parents were positive about the program. Adolescents felt they were more in control of their pain and parents valued the support they experienced in helping their children to master the pain. The training was considered to be feasible in daily life. Further, the preliminary data showed an effect on pain and quality of life in the expected direction. The results underline the need for a definitive study with a larger sample size and a random controlled design.

    Full Text Available Physical Activity (PA is very important during childhood and adolescence in order to promote healthy development and prevent obesity. The WHO recommends 60 minutes daily of moderate-vigorous activity (e» 3 METs/day. The main objective of the study is to assess the levels of PA intensity performed daily by adolescents from a school using the triaxial accelerometry system and to know if they achieve the WHO recommendations. The sample size was 60 Spanish adolescents (14.52 ± .854 year-old belongs to the Empordá school (Empúries, Spain. Previous informed consent was obtained from their parents and/or tutors. PA levels were obtained through accelerometry, Body Mass Index (BMI was calculated though weight and height, heart rate (HR and blood pressure (BP were measured using a digital automatic blood pressure monitor. Descriptive for all data was calculated, and T–test (p < .05 was used to analyze the differences between boys and girls. The main result show that males performed PA during longer time and at higher intensity than women. There is a low percentage of students who achieve the WHO recommendations. In conclusion, we believe very important to seek new strategies and methods to involve more adolescents in the practice of PA, and we believe that PA sessions at school are very important.

    Neurodevelopmental theories of risk behavior hypothesize that low behavioral control in combination with high reward sensitivity explains adolescents' risk behavior. However, empirical studies examining this hypothesis while including actual risk taking behavior in adolescence are lacking. In this study we tested whether the imbalance between behavioral control and reward sensitivity underlies risk taking behavior in adolescence, using a nationally representative longitudinal sample of 715 adolescents, of which 66% revealed an increased risk for mental health problems. To assess behavioral control at age 11 we used both self-report (effortful control) as well as behavioral measures of cognitive control (i.e., working memory and response inhibition). Reward sensitivity was assessed with the Bangor Gambling Task. The main finding of this study was that effortful control at age 11 was the best predictor of risk taking behavior (alcohol and cannabis use) at age 16, particularly among adolescents who were more reward sensitive. Risk taking behavior in adolescents might be explained by relatively weak behavioral control functioning combined with high sensitivity for reward.

    Psychosocial treatments for chronic abdominal pain in childhood or adolescence are effective, but time consuming and hardly available. In the present study, gut-directed hypnotherapy (GDHT) and unspecific hypnotherapy (UHT) were compared to evaluate the feasibility and efficacy of a hypnotherapeutic self-help intervention. Children/adolescents between 6 and 17 years of age with chronic abdominal pain were randomized to GDHT or UHT. The treatment period was 12 weeks each. Measurements were performed before and after treatment. The primary outcome was a pain diary. Analysis was carried out as per protocol. Of 45 participants included, 13 were lost to follow-up. Thirty-two participants (14 GHDT, 18 UHT) were analyzed. Dropouts had higher pain severity. Completers in both conditions showed good adherence and a similar decrease in days with pain and pain duration. Pain intensity decreased only in the UHT condition. Eleven participants (two GDHT, nine UHT) achieved clinical remission (>80% improvement) and 13 participants (seven GDHT, six UHT) improved significantly (30-80%). Results suggest a high efficacy of standardized home-based hypnotherapy for children/adolescents with abdominal pain. Children/adolescents with high pain severity are at risk of dropping out. The UHT condition showed slight evidence of superiority, but conditions were equivalent on most outcomes. Taken together, self-help approaches based on hypnotherapy could close a treatment gap and prevent chronification.

    Full Text Available Abstract Background Data about the predictors of smoking among adolescents in Greece are sparse. We tried to identify factors associated with current cigarette smoking among in-school adolescents in Greece in the context of GYTS study. Methods A secondary analysis of data from a questionnaire study using the Global Youth Tobacco Survey methodology was conducted to identify factors associated with smoking among adolescents in Greece. Data were collected in 2004–2005. The outcome variable was cigarette smoking within the past 30 days preceding the survey while independent variables included age, gender, parental educational status, parental smoking, perception of harmfulness of smoking, and the amount of pocket money at the adolescent's disposal. Results 6141 adolescents (51.5% males and 48.5% females participated in the study. In multivariate analysis, cigarette smoking was associated with male gender (OR: 1.62; 95% CI: 1, 08–3.08, parental smoking (OR: 2.59; 95% CI: 1.45–5.89, and having pocket money ≥ 16 Euros (OR: 2.64; 95% CI: 1.19–5.98. Conclusion Male gender, parental smoking, and having pocket-money ≥ 16 Euros were independently associated with current smoking among Greek students. These findings could be taken into account in order to formulate a comprehensive anti-smoking strategy in Greece.

    The development of new wireless communication technologies that emit radio frequency electromagnetic fields (RF-EMF) is ongoing, but little is known about the RF-EMF exposure distribution in the general population. Previous attempts to measure personal exposure to RF-EMF have used different measurement protocols and analysis methods making comparisons between exposure situations across different study populations very difficult. As a result, observed differences in exposure levels between study populations may not reflect real exposure differences but may be in part, or wholly due to methodological differences. The aim of this paper is to develop a study protocol for future personal RF-EMF exposure studies based on experience drawn from previous research. Using the current knowledge base, we propose procedures for the measurement of personal exposure to RF-EMF, data collection, data management and analysis, and methods for the selection and instruction of study participants. We have identified two basic types of personal RF-EMF measurement studies: population surveys and microenvironmental measurements. In the case of a population survey, the unit of observation is the individual and a randomly selected representative sample of the population is needed to obtain reliable results. For microenvironmental measurements, study participants are selected in order to represent typical behaviours in different microenvironments. These two study types require different methods and procedures. Applying our proposed common core procedures in future personal measurement studies will allow direct comparisons of personal RF-EMF exposures in different populations and study areas.

    A pregnant adolescent's vulnerability increases when she is a victim of intrafamilial violence and drug addiction, which cause physical and biopsychosocial damage to the mother and her baby. Objective Present and analyze the case of an adolescent who is addicted to drugs, pregnant and the victim of lifelong intrafamilial violence. Method A case study based on a semi-structured interview conducted in the Obstetrics Emergency Unit at the Teaching Hospital of the University of São Paulo. The data were interpreted and analyzed using Content Analysis. Results intrafamilial violence experienced at the beginning of the adolescent's early relationships seriously affected her emotional maturity, triggering the development of psychopathologies and leaving her more susceptible to the use and abuse of alcohol and other drugs. The adolescent is repeating her history with her daughter, reproducing the cycle of violence. Conclusion Adolescent pregnancy combined with intrafamilial violence and drug addiction and multiplies the adolescent's psychosocial vulnerability increased the adolescent's vulnerability.

    Full Text Available Increasing evidence suggests that secondhand smoke exposure (SHSE may affect not only physical health, but also mental health. Therefore, we evaluated the association between SHSE and depressive symptoms among Korean adolescents.The JS High School Study enrolled 1071 high school freshmen from a rural community of South Korea. The current analysis was limited to 989 adolescents (495 male and 494 female adolescents, after excluding 48 ever-smokers, 3 students with physician-diagnosed depression, and 31 students who did not complete the depression questionnaire. SHSE was assessed using a self-reported questionnaire and was classified into three groups: none, occasional exposure, and regular exposure. Depressive symptoms were assessed according to the Beck Depression Inventory (BDI score, ranging from 0 to 63, and the presence of depressive symptoms was defined as a BDI score ≥10.Overall, adolescents with SHSE were more likely to have depressive symptoms than those without SHSE (p = 0.042.In a sex-specific analysis treating the BDI score as a continuous variable, regular SHSE was independently associated with higher BDI scores in male adolescents (β = 2.25, p = 0.026, but not in female adolescents (β = 1.11, p = 0.253. Compared to no SHSE, the odds ratio for having depressive symptoms among male adolescents with regular SHSE was 2.17 (95% confidence interval, 1.11 to 4.25 after adjusting for age, body mass index, and study year, and 3.65 (95% confidence interval, 1.52 to 8.73 after adjusting for age, body mass index, study year, exercise, and household income.Regular exposure to secondhand smoke was associated with having depressive symptoms among Korean male adolescents.

    Adolescents constitute about 20% of our population and increasingly more of them are initiating sexual activity at an early age. Several behaviors associated with adolescence like masturbation, expression of masculinity/femininity, lifestyle habits like attending late night parties, and consumption of alcohol have been variously implicated in initiating sexual activities. Sexual abuse can also lead to premature sexualization. In view of few worthwhile studies from India that have dealt with these issues this study was undertaken. To elicit information from two co-education schools adolescent boys and girls on matters related to pubescence, sexual experiences, and sexual health. Study subjects involved students from class IX to XII in two co-education schools. Consent of parents was taken to administer the questionnaire to their wards. A total of 586 out of 1580 students completed a self-reporting questionnaire on matters related to sexuality. Statistical Analysis EpiInfo6 Software was used. Significant association was found among those holding the view that having sex proves their masculinity, being sexually abused, masturbation among boys, and sexual activity. A significantly large number of boys and girls are unaware of role of alcohol on sexual activity and that pregnancy can be caused by single intercourse. This was probably the first such comparative study from India. Mechanisms need to be evaluated to help adolescents understand their sexual attitudes and situations that are likely to provoke sexual activity. Therefore, not only more detailed and longitudinal studies are needed to understand these relations in a better perspective, but also a well-planned educational program for adolescents is a need of the hour.

    2015-02-01

    The aim of this study was to examine the effect of adolescents' exposure to media portraying antisocial and risk behavior on cyberbullying behavior over time. Previous research established relatively high prevalence of cyberbullying behavior among adolescents, although not much is known about the possible predictors of cyberbullying behavior. This study examines the long-term effects of media exposure herein. Furthermore, we examined whether boys and girls differ in this respect. The long-term effects were tested in a longitudinal design with three waves (N = 1,005; age range, 11-17 years; 49% boys). Measured variables: cyberbullying behavior and exposure to media with antisocial and risk behavior content. Results of mixed-model analyses showed that higher levels of exposure to media with antisocial and risk behavior content significantly contributed to higher initial rates of cyberbullying behavior. Moreover, an increase in exposure to antisocial media content was significantly related to an increase in cyberbullying behavior over time. For both boys and girls, higher exposure to antisocial and risk behavior media content increases cyberbullying behavior over time though more clearly for boys than for girls. This study provided empirical support for the amplifying effect of exposure to antisocial media content on adolescents' cyberbullying behavior over time. Results are discussed in view of adolescents' media use and the larger theoretical framework. Copyright © 2015 Society for Adolescent Health and Medicine. Published by Elsevier Inc.

    Background Emotion regulation deficits have been consistently linked to psychopathology in cross-sectional studies. However, the direction of the relationship between emotion regulation and psychopathology is unclear. This study examined the longitudinal and reciprocal relationships between emotion regulation deficits and psychopathology in adolescents. Methods Emotion dysregulation and symptomatology (depression, anxiety, aggressive behavior, and eating pathology) were assessed in a large, diverse sample of adolescents (N = 1,065) at two time points separated by seven months. Structural equation modeling was used to examine the longitudinal and reciprocal relationships between emotion dysregulation and symptoms of psychopathology. Results The three distinct emotion processes examined here (emotional understanding, dysregulated expression of sadness and anger, and ruminative responses to distress) formed a unitary latent emotion dysregulation factor. Emotion dysregulation predicted increases in anxiety symptoms, aggressive behavior, and eating pathology after controlling for baseline symptoms but did not predict depressive symptoms. In contrast, none of the four types of psychopathology predicted increases in emotion dysregulation after controlling for baseline emotion dysregulation. Conclusions Emotion dysregulation appears to be an important transdiagnostic factor that increases risk for a wide range of psychopathology outcomes in adolescence. These results suggest targets for preventive interventions during this developmental period of risk. PMID:21718967

    Caretakers/parents/caregivers/guardians play important roles in improving Sexual and Reproductive Health (SRH) of adolescents. Caretaker-adolescent sexual communication suggested to influence young people's sexual behaviours. Despite this significance, the communication is believed to be low in Unguja due to the increase of risky sexual behaviours among adolescents. This study assessed the pattern of such communication using IMB model as a framework. This is a cross-sectional study targeted caretakers of adolescents aged 15-19. One thousand caretakers of adolescents were interviewed using structured questionnaire. Comparison between male and female caretakers on discussing different SRH topics to both sexes of adolescents was made. The mean-score difference of overall communication was examined using Univariate analysis of variance (ANOVA). Bivariate correlation and simple path analysis via regression was conducted to determine the association of IMB variables in relation to communication practice. This study finds 40.7% of caretakers had ever communicated with their adolescents on SRH matters and 9.2% reported to have had communicated in the past 30 days. The weighted topic measure revealed only 26.5% of caretakers communicated with their adolescents. Both caretakers communicated more with their female adolescents. The communication was more common between same sex and between caretakers and their biological adolescents (p related and associated with communication practice. Caretakers-adolescents communication on SRH in Unguja is low and it is not comprehensive. Caretakers fail to communicate with their adolescents on sensitive issues but do so on less sensitive ones. The pattern of communication found to vary across gender of caretaker and that of adolescent and depends on the nature of relationship between caretaker and adolescent. There is gender differences in selecting SRH topics of discussion. Interventions programmes have to include strategies that

    The association between impulsivity and depressive disorders in adolescence has been little studied at the literature and in our country, yet impulsivity is a major risk factor for suicide. Thus we aimed on this study to evaluate impulsivity in 25 adolescents with Major Depressive Disorder MDD compared to a control sample and to analyze the correlations between impulsivity and clinical features of MDD. Employing a matched case-control design, participants included 25 adolescents with MDD and 75 controls. We have administered the Barratt Impulsivity Scale BIS-11 for the two groups to evaluate impulsivity. Semi structured interviews according DSM 5 criteria were conducted for adolescents with MDD. The Child Depressive Inventory CDI was used to measure depressive symptoms in the control sample. Adolescents with MDD were more impulsive compared to controls according to the BIS-11 in its three domains: motor (24.96±6.26 against 20.6±4.84; p=0.000), attentional (20.88±5.03 against 16.64±3.2; p=0.000) and non planning (28.2±7.26 against 24.44±4.32; p=0.02). Impulsivity was not correlated with clinical features of MDD (suicide attempts, psychiatric comorbidities, antidepressant medication …). Adolescents with MDD seem to be more impulsive than control subjects regardless their clinical features. Whether it is a specific characteristic or a symptom among others of MDD, impulsivity predicts health-related behaviors and associated damage that need to be detected and prevented in time.

    Full Text Available Trust is an important aspect of interpersonal relationships, but little is known about adolescents' interpersonal trust. The aim of the present study was to examine the associations among parental monitoring, parent-adolescent communication, and adolescents' trust in their parents in China.Data in this study were collected as part of the cross-sectional study of children in China. 3349 adolescents (female 48.6%, age range of 12-15 years were randomly selected from 35 secondary schools in April, 2009 and administered to the Adolescent Interpersonal Trust Scale, the Parental Monitoring Scale, and the Parent-Adolescent Communication Scale.Adolescents' trust in their parents was positively related to parental monitoring and parent-adolescent communication. Furthermore, parent-adolescent communication mediated the association between parental monitoring and adolescents' trust in their parents. The mediation model fit data of both genders and three age groups equally well.Parental monitoring and parent-adolescent communication play an importance role in fostering adolescents' trust in their parents.

    North Korean adolescent defectors experience adaptation difficulties along with a wide range of psychosocial problems, but no study has yet examined their Internet addiction symptoms. We compared early traumatic experiences, self-esteem, negative cognition, and Internet addiction symptoms, as well as the relationships between these variables, between North Korean adolescent defectors and South Korean adolescents. Fifty-six North Korean adolescent defectors and 112 age- and sex- matched South Korean adolescents participated. The analyses examined the relationship between traumatic experiences and Internet addiction symptoms, with negative automatic thoughts or low self-esteem as mediators of these relations. North Korean adolescent defectors tended to have higher levels of negative automatic thoughts and more severe Internet addiction symptoms, as well as better self-esteem, than did South Korean adolescents. Furthermore, only among North Korean adolescent defectors, traumatic experiences were positively associated with Internet addition symptoms via increasing negative automatic thoughts. North Korean adolescent defectors are more susceptible to Internet addiction, negative cognitions, and early traumatic experiences compared to South Korean adolescents. However, the cross-sectional design of this study precludes consideration of the causality of these relationships. Interventions aiming to correct negative cognitions and increase self-esteem may be helpful for North Korean adolescent defectors with problematic Internet use. Copyright © 2017 Elsevier B.V.

    Full Text Available Childhood psychiatric disorders are estimated to influence about 9 to 21% of relevant age group and interest in this disorders are increasing all over the world. The growing need to child and adolescent mental health leads the task of establishing proposals and policies in this field to become a priority for governments. The first step of such proposals should be determination of prevalence of child and adolescent mental disorders in that country. However, several major methodological problems make it hard to provide accurate prevalence estimates from epidemiological studies. Most common problems are within the fields of sampling, case definition, case ascertainment and data analyses. Such issues increases the costs of studies and hinder to reach large sample sizes. To minimize these problems, investigators have to be careful on choosing the appropriate methodology and diagnostic tools in their studies. Although there are many interviews and questionnaires for screening and diagnosing in child and adolescent psychiatry, only a few of them are suitable for epidemiological research. In parallel with the improvement in all fields of child and adolescent mental health in our country, some of the major screening and diagnosing tools used in prevalence studies in literature have already been translated and validated in Turkish. Most important of this tools for screening purposes are Child Behavior Checklist and Strengths and Difficulties Questionnaire and for diagnosing purposes are Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version and Development and Well-Being Assessment. The aims of this article are to review the methodological problems of epidemiologic studies in child and adolescent psychiatry and to briefly discuss suitable diagnostic tools for extended sampled epidemiologic studies in our country.

    Full Text Available Abstract Background Within the Self-Determination Theory (SDT framework, the first major study aim was to investigate the SDT tenets in an obese adolescent population by examining the factor structure of the Behavioural Regulation in Exercise Questionnaire-2 (BREQ-2 and by investigating associations between physical activity (PA and motivation in obese adolescents. The second aim was to study differences in motivation according to adolescents' educational level, since lower educated obese adolescent are a sub-risk group for lower PA levels among the obese adolescents. The third aim was to investigate whether attending a residential obesity treatment program could lead to an increase in autonomous motivation towards PA and to see if the treatment effect on motivation was different in low versus high educated youth. Methods For the first study aim, the sample comprised 177 obese adolescents at the start of a 10-month multidisciplinary residential obesity treatment program (BMI = 35.9 ± 6.0 kg/m2, 15.1 ± 1.5 years, 62% girls. A subsample of 65 adolescents (stratified by educational level were divided into low (n = 34 versus high educated (n = 31 as part of the second and third study aim. Motivation was assessed using the BREQ-2 and PA using the Flemish Physical Activity Questionnaire. Results Exploratory factor analysis showed sufficient validations with the original factor for 17 out of 19 BREQ-2 items. Significant positive correlations were found between PA and the composite score of relative autonomy (r = 0.31, p Conclusions The BREQ-2 can be used in an obese adolescent population. Higher levels of autonomous motivation towards PA were related to higher PA levels. Adolescents had increases in both autonomous and controlled forms of motivation during treatment. Special attention for lower educated adolescents during treatment is needed, as they have a lower autonomous motivation at the start of treatment and an increase in introjected

    A broad range of mental disorders are now understood as aberrations of normal adolescent brain development. In both adolescents and adults, executive dysfunction has been implicated across a range of mental illnesses, and enhancing executive functioning may prove to be a useful prevention strategy for adolescents at risk for a range of psychopathology. This study will consist of a double-blind, randomised controlled trial with a 12-month follow-up period. Participants will consist of 200 people aged 16-24 years who are at risk for a range of mental disorders based on personality risk factors, but have not experienced a lifetime mental illness as determined by a structured diagnostic interview. Participants will be randomly allocated to either an intervention group who complete an online cognitive training programme specifically targeting executive functioning ability or a control group who complete an online cognitive training programme that has limited executive functioning training potential. Superiority of the executive functioning training programme compared with the control training programme will be assessed at baseline, post-training and at 3-month, 6-month and 12-month follow-up. All assessments will be conducted online. The primary outcome of the study will be general psychopathology as measured by the Strengths and Difficulties Questionnaire. Secondary outcomes will include executive functioning ability, day-to-day functioning and alcohol consumption. All analyses will be undertaken using mixed-model repeated measures analysis of variance with planned contrasts. Ethics approval has been obtained from the University of New South Wales Human Research Ethics Committee (HC15094). Results of the trial immediately post-treatment and at 12 months follow-up will be submitted for publication in peer-reviewed journals.

    The importance of the family environment for children's and adolescents' health behavior has been demonstrated, the underlying mechanisms of this influence remain unclear. Therefore, the aim of the study was to investigate the relationship between family environmental and individual determinants. It was hypothesized that the Family Health Climate (FHC) is associated with adolescents' physical activity and dietary behavior and that intrinsic motivation mediates this association. Cross-sectional data were collected from 198 families (mother, father, and child) using questionnaires. Perceptions of FHC of mothers, fathers, and their children were assessed using the FHC-scales for physical activity (FHC-PA) and nutrition (FHC-NU). The adolescents also rated their intrinsic motivation for exercise and healthy eating, their physical activity and consumption of healthful food. A structural equation model was analyzed and a bootstrapping procedure was used to test direct and indirect effects. The FHC-PA was related to the amount of weekly physical activity and the FHC-NU to the consumption of fruit, vegetables and salad. These effects were mediated by adolescents' intrinsic motivation; the indirect effects were significant for both behaviors. These results emphasize the importance of the FHC in shaping adolescents' physical activity and dietary behavior. Individual motivational factors are potential mediators of family and parental influences. Considering family-level variables and their interaction with individual factors contributes to the understanding of adolescents' health behavior.

    2018-04-12

    Injury is the leading cause of mortality and morbidity in adolescents worldwide, and injury rates have been shown to be higher among youth with intellectual disability. Despite this, injury among adolescents with intellectual disability remains poorly investigated. This study aimed to identify characteristics associated with injury among adolescents with intellectual disability living in the community. A cohort of adolescents with intellectual disability living in southern Queensland, Australia was investigated prospectively between January 2006 and June 2010. Personal characteristics were collected via postal questionnaire. Injury information, including mechanism and location of injury, was extracted from general practitioner records. The association between demographic, social and clinical characteristics of participants and episodes of injury was investigated using negative binomial regression. A total of 289 injuries were recorded from 432 participants over 1627.3 years of study-time. The overall annual injury incidence was 17.5 (95%CI 14.7, 20.9) per 100 person years. Presence of ADHD and less severe disability was associated with increased risk of injury. Down syndrome and reduced verbal communication capacity were associated with decreased risk of injury. Falls accounted for the highest single mechanism of injury (19.0%) with the majority (73.2%) of injuries involving either upper or lower limbs. ADHD is a co-morbidity that increases risk of injury among adolescents with intellectual disability. A critical component of injury prevention is avoidance of the great variety of environmental risk factors for injury relevant to this population. Copyright © 2018 Elsevier Ltd. All rights reserved.

    The purpose of this study was to determine the physical and psychosocial impact of gynecomastia and its severity on adolescents seeking treatment as compared with healthy adolescent males. The following surveys were administered to adolescents with gynecomastia and healthy male controls, aged 12 to 21 years: Short Form-36 Version 2, the Rosenberg Self-Esteem Scale, and the Eating Attitudes Test-26. Demographic variables were compared between the two groups, and controls were administered a short chest symptoms survey. Linear regression models, unadjusted and adjusted for body mass index category, were fit to determine the effect of case status and graded severity of gynecomastia on survey score. Forty-seven patients with gynecomastia and 92 male control subjects participated in this study. There was no difference in mean age between the groups, although patients with gynecomastia had a significantly higher body mass index. Gynecomastia subjects had three lower Short Form-36 domain and Rosenberg Self-Esteem Scale scores independent of body mass index category as compared with controls, although there was no difference in Eating Attitudes Test-26 scores between the groups. Graded gynecomastia severity had no effect on survey scores, all independent of body mass index category. Gynecomastia has a significant negative impact on primarily the psychosocial well-being of affected adolescent patients, specifically in regard to social functioning, mental health, and self-esteem. Psychosocial impact was not affected by graded severity of disease. Health care providers and patients should be aware of the psychosocial impairments associated with gynecomastia and consider early treatment for adolescents suffering from this condition, regardless of severity.

    To evaluate the prevalence of sexual activity and contraception methods used by Greek adolescents. To assess the effect of various factors in the decision making on sexual activity. A cross-sectional study design was applied. SETTING-PARTICIPANTS: The population (N = 1538) consisted of a random sample, stratified according to locality and population density, of 20 public junior high and high schools located in the urban district of Athens, Greece. Anonymous self-completed questionnaires were used to assess sexual practices, contraception methods, and factors affecting sexual activity choices. Spearman association calculations and chi-square were used, while regression analysis models were also applied. We examined the sexual practices among Greek adolescents, and indicated the psychosocial factors that may influence adolescents' sexual behavior. 16% of the adolescents have had sexual intercourse, while the boy/girl ratio was 3/1 (P divorce, recent death, not living with mother) or sexually experienced peers, as well as those that seek sexual education from siblings or friends have higher possibilities of being sexually active. Greek adolescents can be sexually active at a young age and they need sexual education on safe sex practices. Copyright © 2010 North American Society for Pediatric and Adolescent Gynecology.

    Full Text Available The objective of this study was to determine time trends (1982–2006 in total fat intake and changes in fatty acid structure intake in adolescents from Warsaw in view of increasing prevalence of obesity. Data come from four successive surveys randomly selected samples of adolescents (aged 11–15 years old, from Warsaw region. In total 9747 pupils have been examined, with response rate varying from 55% to 87% depending on year. Surveys were done always in the spring season of the year. Food intake was assessed by using 24 hours recall method of consumption by the pupils all products, including enriched, dishes and beverages as well as diet supplements, in the last 24 hours preceding the examination. The content of energy and nutrients was calculated by means of own computer softwares (DIET 2 and 4, taking into account successive revisions of the tables of food composition and nutritional values, as well as current Polish DRI. A significant decreasing trend was found in intake of total fat, of saturated fatty acids (SFA and cholesterol. The percentage of energy from total fat, also decreased both in boys (to 35,1% and girls (to 33,7%, what failed to reach the desired level below 30% of energy from fat which is recommended. Also significant decrease of SFA consumption was not satisfactory enough to approach the values <10% of energy recommended as was from 13% to 15%. Decreasing trends in fat intake was not in accordance with the trend in obesity prevalence in the adolescents as average BMI is going up. To stabilize the health-oriented changes especially in the diets of adolescents, further activity is desired from professionals working with prevention of adolescents obesity.

    To learn about the overall quality of clinical anaesthesia study protocols from the Chinese Clinical Trials Registry and to discuss the way to improve study protocol quality. We defined completeness of each sub-item in SPIRIT as N/A (not applicable) or with a score of 0, 1, or 2. For each protocol, we calculated the proportion of adequately reported items (score = 2 and N/A) and unreported items (score = 0). Protocol quality was determined according to the proportion of reported items, with values >50% indicating high quality. Protocol quality was determined according to the proportion of reported items. For each sub-item in SPIRIT, we calculated the adequately reported rate (percentage of all protocols with score 2 and NA on one sub-item) as well as the unreported rate (percentage of all protocols with score 0 on one sub-item). Total 126 study protocols were available for assessment. Among these, 88.1% were assessed as being of low quality. By comparison, the percentage of low-quality protocols was 88.9% after the publication of the SPIRIT statement. Among the 51 SPIRIT sub-items, 18 sub-items had an unreported rate above 90% while 16 had a higher adequately reported rate than an unreported rate. The overall quality of clinical anaesthesia study protocols registered in the ChiCTR was poor. A mandatory protocol upload and self-check based on the SPIRIT statement during the trial registration process may improve protocol quality in the future.

    There has been increasing acceptance of marijuana use in the United States in recent years, and rates among adolescents have risen. At the same time, marijuana use during adolescence has been linked to an array of health and social problems. Maltreated children are at risk for marijuana use, but the relationships among characteristics of maltreatment and marijuana use are unclear. In this article, we examine how the type and the extent of maltreatment are related to the level of adolescent marijuana use. Data analyses were conducted on a subsample of maltreated adolescents (n = 702) from the Longitudinal Studies of Child Abuse and Neglect project. Approximately half the sample had used marijuana, and maltreatment was associated with its use. Multivariate regression models showed that being male, extensive maltreatment, and peer marijuana use were associated with heavy use of marijuana. These findings suggest the importance of comprehensively assessing children's maltreatment experiences and their peers' drug use to help prevent or address possible marijuana use in these high-risk adolescents. © The Author(s) 2015.

    The purpose of the study was to validate the ambulatory blood pressure monitoring (ABPM) device custo screen pediatric in children aged 3 to 12 years according to the International Protocol of the European Society of Hypertension (ESH-IP revision 2010). Thirty-three children were included and systolic and diastolic blood pressure measurements were performed according to the ESH-IP. The protocol was modified for children considering data from the German Health Interview and Examination Survey for Children and Adolescents (KIGGS). The custo screen pediatric met all the requirements of the ESH-IP. The mean difference between the test device and the reference was -1.4 ± 3.0 mmHg for systolic blood pressure (SBP) and -0.7 ± 3.2 mmHg for diastolic blood pressure (DBP). For SBP and DBP, all 99 measurements were within the absolute difference of 10 mmHg between the test device and the reference. As to part 2 of the protocol, for DBP in all subjects, two out of three measurements were within 5 mmHg between the device and the standard, whereas for SBP in 32 of 33 subjects, two out of three measurements were within this range. The custo screen pediatric met all criteria of the ESH-IP review 2010, modified for children from 3 to about 12 years, and can be recommended for ABPM in children. What is Known: • Validation of blood pressure measuring devices is essential to provide patients with an accurate blood pressure measuring device. • The majority of devices has not been validated in children. What is New: • Prior to the present validation, study protocol adjustments of ESH-IP review 2010 for children were defined according to German Health Interview and Examination Survey for Children and Adolescents 2013 (KIGGS). • The custo screen pediatric test device met all criteria of ESH-IP revision 2010, modified for children, and can be recommended for ABPM in children aged 3 to about 12 years.

    2016-06-01

    The Victorian Adolescent Health Cohort Study (VAHCS) is a long-term Australian cohort study that has documented cannabis use in young Australians from the mid-teens to the mid-30s. The study findings have described the natural history of early cannabis use, remission, and escalation and the social and mental health consequences of different patterns of use. The adverse consequences of cannabis use are most clear-cut in heavy early adolescent users. These consequences include educational failure, persisting mental health problems, and progression to other substance use. For later onset and occasional users, the risks are lower and appear to entail modest elevations in risk for other drug use compared with never users. With growing evidence of health consequences, there is a strong case for actions around early heavy adolescent users. Prevention of early use, identification and treatment of early heavy users, and harm reduction through diversion of early heavy users away from the custodial justice system into health care are all priority responses. © The Author(s) 2016.

    We sought to evaluate the prenatal decision-making of pregnant adolescents identified at increased risk for identifiable fetal genetic abnormalities. A retrospective review of records of gravid women 19 years old or younger undergoing genetic counseling from 2001-2003 (inclusive) was undertaken. Hospital-based academic center. Thirty-seven women were identified; four cases did not meet inclusion criteria. None. Decision to undergo or forgo invasive prenatal testing. Of the 33 women included in this study, the average age was 17.6 years (range: 15-19). Eighteen were Latinas, eight were African-Americans, and seven were Caucasians. Sixteen women had positive maternal serum screening outcomes; nine women sought counseling because of personal/family histories of genetic abnormalities, seven sought counseling after fetal structural anomalies were detected by ultrasound, and one woman sought counseling because she and her partner were positive for Mendelian disorder screening (sickle cell disease). Sixteen of the women (48.5%) chose to undergo invasive testing (15 amniocenteses, one chorionic villus sampling) whereas 17 (51.5%) chose to forgo invasive testing. Adolescents offered invasive prenatal diagnosis will chose to undergo or forgo such testing based on diagnostic and personal criteria as do adult women. Nonetheless, unique adolescent issues may make the process by which information is obtained and communicated during counseling to be different from counseling provided to adults. The development of new genetic screening and diagnostic protocols has and will increase the number of pregnant adolescent women who will be offered genetic counseling during their pregnancies. Such an increase in numbers will place considerably more pressure on an already taxed genetic counseling system; accordingly, new counseling paradigms will need to be developed to provide service to an expanded patient population seeking information for an increasing number of genetic issues.

    Adolescents with psychiatric conditions may be at risk for xerostomia. In this preliminary study, we estimated xerostomia prevalence in adolescents ages 9 to 17 years from an inpatient psychiatric clinic (N = 25) and examined whether: (1) gender and age were associated with xerostomia and (2) xerostomia was associated with self-reported cavities. We used a modified 11-item Xerostomia Index to identify xerostomia (no/yes) and asked if adolescents ever had or currently have cavities (no/yes). The mean age was 14 years (SD = 2.3) and 72% were male. Sixty percent reported xerostomia (SD = 50). There were no significant associations between xerostomia and gender (p = 0.99) or age (p = 0.66), or between xerostomia and past (p = 0.26) or current cavities (p = 0.11). Larger proportions of adolescents with xerostomia reported previous and current cavities. Sixty percent of adolescents from an inpatient psychiatric clinic reported having xerostomia, which may lead to increased caries risk over time. Additional research should examine the prevalence and consequences of xerostomia in high-risk adolescents. © 2015 Special Care Dentistry Association and Wiley Periodicals, Inc.

    To build up sufficient knowledge of a 'healthy diet'. Here, we report on the assessment of nutritional knowledge using a uniform method in a large sample of adolescents across Europe. A cross-sectional study. The European multicentre HELENA (Healthy Lifestyle in Europe by Nutrition in Adolescence) study conducted in 2006-2007 in ten cities in Austria, Belgium, France, Germany, Greece (one inland and one island city), Hungary, Italy, Spain and Sweden. A total of 3546 adolescents (aged 12·5-17·5 years) completed a validated nutritional knowledge test (NKT). Socio-economic variables and anthropometric data were considered as potential confounders. NKT scores increased with age and girls had higher scores compared with boys (62% v. 59%; P Nutritional knowledge was modest in our sample. Interventions should be focused on the lower SES segments of the population. They should be initiated at a younger age and should be combined with environmental prevention (e.g. healthy meals in school canteens).

    Little work has been conducted that examines the effects of positive environmental experiences on brain development to date. The aim of this study was to prospectively investigate the effects of positive (warm and supportive) maternal behavior on structural brain development during adolescence, using longitudinal structural MRI. Participants were 188 (92 female) adolescents, who were part of a longitudinal adolescent development study that involved mother-adolescent interactions and MRI scans at approximately 12 years old, and follow-up MRI scans approximately 4 years later. FreeSurfer software was used to estimate the volume of limbic-striatal regions (amygdala, hippocampus, caudate, putamen, pallidum, and nucleus accumbens) and the thickness of prefrontal regions (anterior cingulate and orbitofrontal cortices) across both time points. Higher frequency of positive maternal behavior during the interactions predicted attenuated volumetric growth in the right amygdala, and accelerated cortical thinning in the right anterior cingulate (males only) and left and right orbitofrontal cortices, between baseline and follow up. These results have implications for understanding the biological mediators of risk and protective factors for mental disorders that have onset during adolescence. Copyright © 2013 The Authors.

    A cross-sectional school-based survey study (N=13,284; 53% females; mean age 15.8±0.7) of 14-17-year-old adolescents was conducted in seven European countries (Greece, Spain, Poland, Germany, Romania, the Netherlands, and Iceland). The aim of the study was to investigate the prevalence of Internet addictive behavior (IAB) and related psychosocial characteristics among adolescents in the participating countries. In the study, we distinguish two problematic groups: adolescents with IAB, characterized by a loss of control over their Internet use, and adolescents "at risk for IAB," showing fewer or weaker symptoms of IAB. The two groups combined form a group of adolescents with dysfunctional Internet behavior (DIB). About 1% of adolescents exhibited IAB and an additional 12.7% were at risk for IAB; thus, in total, 13.9% displayed DIB. The prevalence of DIB was significantly higher among boys than among girls (15.2% vs. 12.7%, p<0.001) and varied widely between countries, from 7.9% in Iceland to 22.8% in Spain. Frequent use of specific online activities (e.g., gambling, social networking, gaming) at least 6 days/week was associated with greater probability of displaying DIB. Multiple logistic regression analysis indicated that DIB was more frequent among adolescents with a lower educational level of the parents, earlier age at first use of the Internet, and greater use of social networking sites and gaming sites. Multiple linear regression analysis showed that externalizing (i.e., behavioral) and internalizing (i.e., emotional) problems were associated with the presence of DIB.

    Major depression (MD) is associated with deficits in selective attention. Previous studies in adults with MD using event-related potentials (ERPs) reported abnormalities in the neurophysiological correlates of auditory selective attention. However, it is yet unclear whether these findings can be generalized to MD in adolescence. Thus, the aim of the present ERP study was to explore the neural mechanisms of auditory selective attention in adolescents with MD. 24 male and female unmedicated adolescents with MD and 21 control subjects were included in the study. ERPs were collected during an auditory oddball paradigm. Depressive adolescents tended to show a longer N100 latency to target and non-target tones. Moreover, MD subjects showed a prolonged latency of the P200 component to targets. Across groups, longer P200 latency was associated with a decreased tendency of disinhibited behavior as assessed by a behavioral questionnaire. To be able to draw more precise conclusions about differences between the neural bases of selective attention in adolescents vs. adults with MD, future studies should include both age groups and apply the same experimental setting across all subjects. The study provides strong support for abnormalities in the neurophysiolgical bases of selective attention in adolecents with MD at early stages of auditory information processing. Absent group differences in later ERP components reflecting voluntary attentional processes stand in contrast to results reported in adults with MD and may suggest that adolescents with MD possess mechanisms to compensate for abnormalities in the early stages of selective attention.

    We examined the moderating effects of parenting on the temporal relationship between negative affect and subsequent alcohol use in adolescents as an indicator of self-medication. Specifically, we tested whether youth are more likely to self-medicate if they receive less parental social support. We used a multi-method, multi-reporter strategy and an experience sampling paradigm to examine these mechanisms in an elevated-risk sample preparing for the transition to high school. Seventy-one adolescents and their parents completed home-based interviews and adolescents completed a 21-day experience sampling protocol in which they reported their alcohol use daily and their affect thrice daily. Parent-reported family communication, though no other parental support indicators, moderated the relation between daily negative affect and alcohol use. Plotting of interactions showed a greater likelihood of drinking on days characterized by greater negative affect only in adolescents with higher levels of parent-reported family communication. This study offers tentative support for parental support as a moderator of the relation between daily negative affect and alcohol use. Parental support may be a response to alcohol use and self-medication in teens such that parents become more involved and open in talking with their teens when they notice these patterns of behavior.

    Childhood maltreatment is an important risk factor for mental and physical health problems. Adolescents living in residential youth care (RYC) have experienced a high rate of childhood maltreatment and are a high-risk group for psychiatric disorders. Quality of life (QoL) is a subjective, multidimensional concept that goes beyond medical diagnoses. There is a lack of research regarding the associations between childhood maltreatment and QoL. In the present study, we compare self-reported QoL between adolescents in RYC in Norway with and without maltreatment histories, and adolescents from the general population. We also study the impact of number of types of adversities on QoL. Adolescents aged 12-23 years living in RYC in Norway were invited to participate in the study; 400 participated, yielding a response rate of 67 %. Maltreatment histories were assessed through interviews with trained research assistants, and completed by 335 adolescents. Previous exposure to maltreatment was reported by 237 adolescents. The Questionnaire for Measuring Health-Related Quality of Life in Children and Adolescents (KINDL-R) was used. Nonexposed peers in RYC (n = 98) and a sample of adolescents from the general population (n = 1017) were used for comparison. General linear model analyses (ANCOVA) were conducted with five KINDL-R life domains as dependent variables. Linear regression was used to study the effect of number of types of adversities. Exposed adolescents in RYC reported poorer QoL than peers in control groups. Compared with nonexposed peers in RYC, the 95 % confidence intervals for mean score differences on the KINDL-R subdomains (0-100 scale) were 1.9-11.4 (Physical Well-being), 2.2-11.1 (Emotional Well-being), -0.7-10.0 (Self-esteem), and 1.8-10.9 (Friends). Compared with the general population sample, the 95 % confidence intervals for mean score differences were 9.7-17.6 (Physical Well-being), 7.9-15.3 (Emotional Well-being), 3.6-12.5 (Self-esteem), and 5

    Full Text Available A cost-effective and interactive way of promoting healthy nutrition behaviors among adolescents is using information and communication technologies (ICTs. We systematically reviewed studies to identify technologies and their main characteristics used for nutritional interventions for adolescents, as well as to evaluate their quality and effectiveness. Our full protocol is available on the PROSPERO website (#CRD42016035882. A search was conducted across five databases for articles describing nutritional interventions that used ICTs designed mainly for healthy adolescents. Randomized controlled trials, quasi-experimental and observational studies, and full and original papers, all of them published from 2005 to 2015, were included. Study quality was assessed by the Effective Public Health Practice Project Quality Assessment Tool. Our search yielded 559 titles and abstracts. Eleven studies met the inclusion criteria. Participants were recruited mostly from schools. Study follow-up ranged from two weeks to two years. Four interventions were based on the Social Cognitive Theory. Interventional strategies included computer games, programs, text messages, and interactive CD-ROMs. Nine studies used computer-mediated ICTs. Five studies focused on multiple behaviors simultaneously. Participants were exposed to interventions only once, daily, weekly, or according to a pre-determined number of lessons. Five studies had significant outcomes. Our quality assessment revealed three studies to be weak due to non-representativeness of their samples and usage of non-validated questionnaires. Besides the heterogeneity and poor quality of the analyzed studies, it can be suggested that long-term interventions for adolescents that make use of frequent exposure to technological resources, and that have a theoretical component aimed at a single health behavior change, tend to be more successful.

    The study examined the validity of the Line Drill test (LD) in male adolescent basketball players (10-15 years). Sensitiveness of the LD to changes in performance across a training and competition season (4 months) was also considered. Age, maturation, body size and LD were measured (n = 57). Sensitiveness of the LD was examined pre- and post-competitive season in a sub-sample (n = 44). The time at each of the four shuttle sprints of the LD (i.e. four stages) was modelled with Bayesian multilevel models. We observed very large correlation of performance at stage 4 (full LD protocol) with stage 3, but lower correlations with the early LD stages. Players' performance by somatic maturity differed substantially only when considering full LD protocol performance. Substantial improvements in all stages of the protocol were observed across the 4-month competitive season. The LD protocol should be shortened by the last full court shuttle sprint, remaining sensitive to training exposure, and independent of maturity status and body size.

    Full Text Available Abstract Background The development of new wireless communication technologies that emit radio frequency electromagnetic fields (RF-EMF is ongoing, but little is known about the RF-EMF exposure distribution in the general population. Previous attempts to measure personal exposure to RF-EMF have used different measurement protocols and analysis methods making comparisons between exposure situations across different study populations very difficult. As a result, observed differences in exposure levels between study populations may not reflect real exposure differences but may be in part, or wholly due to methodological differences. Methods The aim of this paper is to develop a study protocol for future personal RF-EMF exposure studies based on experience drawn from previous research. Using the current knowledge base, we propose procedures for the measurement of personal exposure to RF-EMF, data collection, data management and analysis, and methods for the selection and instruction of study participants. Results We have identified two basic types of personal RF-EMF measurement studies: population surveys and microenvironmental measurements. In the case of a population survey, the unit of observation is the individual and a randomly selected representative sample of the population is needed to obtain reliable results. For microenvironmental measurements, study participants are selected in order to represent typical behaviours in different microenvironments. These two study types require different methods and procedures. Conclusion Applying our proposed common core procedures in future personal measurement studies will allow direct comparisons of personal RF-EMF exposures in different populations and study areas.

    Low caste adolescent girls living in rural northern Karnataka are at increased risk of school drop-out, child marriage, and entry into sex-work, which enhances their vulnerability to HIV, early pregnancy and adverse maternal and child health outcomes. This protocol describes the evaluation of Samata, a comprehensive, multi-level intervention designed to address these structural drivers of HIV risk and vulnerability. The Samata study is a cluster randomised controlled trial that will be conducted in eighty village clusters (40 intervention; 40 control) in Bijapur and Bagalkot districts in northern Karnataka. The intervention seeks to reach low caste girls and their families; adolescent boys; village communities; high school teachers and school governing committees; and local government officials. All low caste (scheduled caste/tribe) adolescent girls attending 7th standard (final year of primary school) will be recruited into the study in two consecutive waves, one year apart. Girls (n = 2100), their families (n = 2100) and school teachers (n = 650) will be interviewed at baseline and at endline. The study is designed to assess the impact of the intervention on four primary outcomes: the proportion of low caste girls who (i) enter into secondary school; (ii) complete secondary school; (iii) marry before age 15; and (iv) engage in sex before age 15. Observers assessing the outcomes will be blinded to group assignment. The primary outcome will be an adjusted, cluster-level intention to treat analysis, comparing outcomes in intervention and control villages at follow-up. We will also conduct survival analyses for the following secondary outcomes: marriage, sexual debut, pregnancy and entry into sex work. Complementary monitoring and evaluation, qualitative and economic research will be used to explore and describe intervention implementation, the pathways through which change occurs, and the cost-effectiveness of the intervention. This is an innovative

    Full Text Available The objective of the present study is to evaluate and compare the effect of a nutritional intervention between adolescent and adult. In a before and after quasi-experimental clinical study, 32 athletes (21 adults, age range 20–32 years; 11 adolescents, age range: 12–19 years participated in a nutritional counselling consisting of four consultations separated by an interval of 45 to 60 days. The athlete’s eating behaviour, body composition and nutrition knowledge were evaluated at the beginning and at the end of the protocol. Both groups increased lean body mass and nutritional knowledge. Adolescents increased their mid-arm muscle circumference and improved meal frequency, and daily water intake. Athletes of both groups improved their ingestion of vegetables and fruits and decreased the ingestion of sweets and oils. Adolescents showed a higher prevalence of individuals that remained within or approached to the recommendations of sweets. This is the first study to evaluate and compare the effect of a nutritional intervention between adolescent and adult athletes body composition, eating behaviour and nutritional knowledge. The nutritional counselling has been effective in promoting beneficial changes on the athlete’s eating behaviour, nutritional knowledge and body composition, however, some healthy changes were only experienced by adolescents, especially in the frequency of meals and the intake of sweets.

    Few studies have investigated factors that influence physical activity behavior during the transition from adolescence to adulthood. This study explores the associations of sociodemographic, behavioral, sociocultural, attitudinal and physical factors measured in childhood and adolescence with physical activity behavior during the transition from adolescence to adulthood. Childhood and adolescent data (at ages 7-15 years) were collected as part of the 1985 Australian Health and Fitness Survey and subdivided into sociodemographics (socioeconomic status, parental education), behavioral (smoking, alcohol, sports diversity, outside school sports), sociocultural (active father, active mother, any older siblings, any younger siblings, language spoken at home), attitudinal (sports/recreational competency, self-rated health, enjoyment physical education/physical activity, not enjoying school sports) and physical (BMI, time taken to run 1.6 km, long jump) factors. Physical activity between the ages 15 and 29 years was reported retrospectively using the Historical Leisure Activity Questionnaire at follow-up in 2004-2006 by 2,048 participants in the Childhood Determinants of Adult Health Study (CDAH). Australia's physical activity recommendations for children and adults were used to categorize participants as persistently active, variably active or persistently inactive during the transition from adolescence to adulthood. For females, perceived sports competency in childhood and adolescence was significantly associated with being persistently active (RR=1.88, 95% CI=1.39, 2.55). Smoking (RR=0.31 CI=0.12, 0.82) and having younger siblings (RR=0.69 CI=0.52, 0.93) were inversely associated with being persistently active after taking physical and attitudinal factors into account. For males, playing sport outside school (RR=1.47 CI=1.05, 2.08), having active fathers (RR=1.25 CI=1.01, 1.54) and not enjoying school sport (RR=4.07 CI=2.31, 7.17) were associated with being persistently

    Full Text Available Anne Marie Kleinke, Carl Friedrich Classen Oncology and Hematology Unit, Children’s Hospital, University Medicine Rostock, Rostock, Germany Purpose: For adolescents and young adults (AYAs, a cancer diagnosis represents an extraordinary strike in a vulnerable phase of life. They have special needs that the medical system has to take into consideration, and they exhibit a lower degree of therapy adherence than both older and younger patients. The purpose of this study was first to analyze the adherence of AYAs with cancer compared to a group of older patients and, second, to determine correlated parameters, with focus on the psychosocial interaction between physicians and patients. Patients and methods: In 2012, a complete 1 year cohort of patients reported, by use of a questionnaire, to the Rostock clinical cancer registry, and a group of older patients were invited to answer a multi-item set of questionnaires on a volunteer basis, leading to a population-based cross-sectional analysis. This included a bias due to non-answering which is unavoidable in such a setting. The questionnaire consisted of well-established standard questionnaires, a questionnaire on adherence that has just recently been published, and a self-written questionnaire focusing on patient–physician relationship. The responses were analyzed for our current study. Results: Gender, religion, education, age, anxiety, family atmosphere, or physician–patient relationship were not significantly correlated to adherence in AYAs. However, markedly more AYAs, as compared to the older patients group, considered breaking off therapy and reported suboptimal communication with the physicians. Only the perceived physical illness could be identified as a factor related to adherence among the AYA group.Conclusion: Our findings confirm the need for more focused approaches to serve the special needs of AYAs, with particular attention on specific items that showed up discriminating AYAs from

    The present study aimed to evaluate the relationship between the consumption of selected food groups and insulin resistance, with an emphasis on sugar-sweetened beverages (SSB). The present research is a large multicentre European study in adolescents, the HELENA-CSS (Healthy Lifestyle in Europe by Nutrition in Adolescence Cross-Sectional Study). Homeostasis model assessment-insulin resistance index (HOMA-IR) was calculated. Several anthropometric and lifestyle characteristics were recorded. Dietary assessment was conducted by using a short FFQ. The participants were a subset of the original sample (n 546) with complete data on glucose, insulin and FFQ. All participants were recruited at schools. Median (25th, 75th percentile) HOMA-IR was 0.62 (0.44, 0.87). Mean HOMA-IR was significantly higher among adolescents consuming brown bread ≤1 time/week than among those consuming 2-6 times/week (P = 0·011). Mean values of HOMA-IR were also higher in adolescents consuming SSB >5 times/week compared with those consuming less frequently, although a statistically significant difference was detected between those consuming SSB 5-6 times/week and 2-4 times/week (P = 0.049). Multiple linear regression analysis showed that only the frequency of SSB consumption was significantly associated with HOMA-IR after controlling for potential confounders. In particular, it was found that HOMA-IR levels were higher among adolescents consuming SSB 5-6 times/week and ≥1 time/d compared with those consuming ≤1 time/week by 0.281 and 0.191 units, respectively (P = 0.009 and 0.046, respectively). The present study revealed that daily consumption of SSB was related with increased HOMA-IR in adolescents.

    In this study, our objective is to assess the perception of family environments by adolescents with ADHD based on perceived expressed emotion (EE) and the self-esteem of the adolescents. Uludag University Medical Faculty Hospital completed this study with 41 adolescents with ADHD and 35 control group participants who were matched based on age and gender. The total scores of perceived EE, described as a lack of emotional support, irritability, and intrusiveness, were significantly higher in ADHD group than in the control group. The group with ADHD also showed significantly lower self-esteem. There was a negative correlation between self-esteem scores and total perceived EE scores in the ADHD group and the control group. This study showed that the adolescents with ADHD perceive less emotional support and higher levels of intrusiveness, with patients also describing their families as more irritating. Other results in this study show that adolescents with less emotional support possess lower self-esteem, as do adolescents with more irritable parents.

    2011-01-01

    When suffering from cystic fibrosis (CF), a number of problems may arise during adolescence; for example, poor adherence. The problems may be attributed to the adolescent being insufficiently prepared for adult life. Research on different ways of parenting adolescents with CF and the influence of different parenting styles on the adolescents' adherence to treatment is still limited. The aim of this study was to identify the types of parental support that adolescents and young adults with CF want and find helpful in terms of preparing them for adult life. Sixteen Danish adolescents with CF, aged 14-25, participated in the study. Two focus group interviews were carried out, one for 14-18-year-olds and one for 19-25-year-olds. Individual interviews were conducted, with three subjects. Using interpretive description strategy, a secondary analysis of the interview data was conducted. The adolescents and young adults wanted their parents educated about the adolescent experience. They wanted their parents to learn a pedagogical parenting style, to learn to trust them, and to learn to gradually transfer responsibility for their medical treatment. Additionally, the adolescents noted that meeting other parents may be beneficial for the parents. The findings of this study suggest that adolescents and young adults with CF want their parents to be educated about how to handle adolescents with CF and thereby sufficiently prepare them for adult life.

    Full Text Available Abstract Background Previous research has shown that between 80 and 90 percent of adult smokers report having started smoking before 18 years of age. Several studies have revealed that multiple social factors influence the likelihood of smoking during adolescence, the period during which the onset of smoking usually occurs. To better understand the social mechanisms that influence adolescent smoking, we analyzed the relationship and relative importance of a broad spectrum of social variables in adolescent smoking in Iceland, a Nordic country with high per-capita income. Methods We used cross-sectional data from 7,430 14- to 16 year-old students (approximately 81% of all Icelanders in these age cohorts in the 2006 Youth in Iceland study. The Youth in Iceland studies are designed to investigate the role of several cognitive, behavioral, and social factors in the lives of adolescents, and the data collected are used to inform the design, implementation, and evaluation of substance use prevention programs that are being developed by Icelandic social scientists, policy makers, and practitioners. Results Our analysis revealed that friends' smoking behavior and attitude toward smoking were strongly associated with adolescent smoking and other tobacco use, as well as alcohol consumption during the previous 30 days. Main protective factors were parent's perceived attitude toward smoking, the quantity of time spent with parents, absence of serious verbal conflict between parents and adolescents, and participation in physical activity. Family structure was related to adolescent smoking to a small extent, but other background factors were not. Conclusion We conclude that multiple social factors are related to adolescent smoking. Parents and other primary preventive agents need to be informed about the complicated nature of the adolescent social world in order to maximize their impact.

    Wireless sensor networks (WSNs) consist of lightweight devices with low cost, low power, and short-ranged wireless communication. The sensors can communicate with each other to form a network. In WSNs, broadcast transmission is widely used along with the maximum usage of wireless networks and their applications. Hence, it has become crucial to authenticate broadcast messages.

    Wireless sensor networks (WSNs) consist of lightweight devices with low cost, low power, and short-ranged wireless communication. The sensors can communicate with each other to form a network. In WSNs, broadcast transmission is widely used along with the maximum usage of wireless networks and their applications. Hence, it has become crucial to authenticate broadcast messages. Key management is also an active research topic in WSNs. Several key management schemes have been introduced, and their benefits are not recognized in a specific WSN application. Security services are vital for ensuring the integrity, authenticity, and confidentiality of the critical information. Therefore, the authentication mechanisms are required to support these security services and to be resilient to distinct attacks. Various authentication protocols such as key management protocols, lightweight authentication protocols, and broadcast authentication protocols are compared and analyzed for all secure transmission applications. The major goal of this survey is to compare and find out the appropriate protocol for further research. Moreover, the comparisons between various authentication techniques are also illustrated.

    To assess the impact of a tiered patient immunization navigator intervention (immunization tracking, reminder/recall, and outreach) on improving immunization and preventive care visit rates in urban adolescents. Randomized clinical trial allocating adolescents (aged 11-15 years) to intervention vs standard of care control. Eight primary care practices. Population-based sample of adolescents (N = 7546). Immunization navigators at each practice implemented a tiered protocol: immunization tracking, telephone or mail reminder/recall, and home visits if participants remained unimmunized or behind on preventive care visits. Immunization rates at study end. Secondary outcomes were preventive care visit rates during the previous 12 months and costs. The intervention and control groups were similar at baseline for demographics (mean age, 13.5 years; 63% black, 14% white, and 23% Hispanic adolescents; and 74% receiving Medicaid), immunization rates, and preventive care visit rates. Immunization rates at the end of the study were 44.7% for the intervention group and 32.4% for the control group (adjusted risk ratio, 1.4; 95% confidence interval, 1.3-1.5); preventive care visit rates were 68.0% for the intervention group and 55.2% for the control group (1.2; 1.2-1.3). Findings were similar across practices, sexes, ages, and insurance providers. The number needed to treat for immunizations and preventive care visits was 9. The intervention cost was $3.81 per adolescent per month; the cost per additional adolescent fully vaccinated was $465, and the cost per additional adolescent receiving a preventive care visit was $417. A tiered tracking, reminder/recall, and outreach intervention improved immunization and preventive care visit rates in urban adolescents. clinicaltrials.gov Identifier: NCT00581347.

  17. Reward-centricity and attenuated aversions: An adolescent phenotype emerging from studies in laboratory animals.

    Adolescence is an evolutionarily conserved developmental period, with neural circuits and behaviors contributing to the detection, procurement, and receipt of rewards bearing similarity across species. Studies with laboratory animals suggest that adolescence is typified by a "reward-centric" phenotype-an increased sensitivity to rewards relative to adults. In contrast, adolescent rodents are reportedly less sensitive to the aversive properties of many drugs and naturally aversive stimuli. Alterations within the mesocorticolimbic dopamine and endocannabinoid systems likely contribute to an adolescent reward-sensitive, yet aversion-resistant, phenotype. Although early hypotheses postulated that developmental changes in dopaminergic circuitry would result in a "reward deficiency" syndrome, evidence now suggests the opposite: that adolescents are uniquely poised to seek out hedonic stimuli, experience greater "pleasure" from rewards, and consume rewarding stimuli in excess. Future studies that more clearly define the role of specific brain regions and neurotransmitter systems in the expression of behaviors toward reward- and aversive-related cues and stimuli are necessary to more fully understand an adolescent-proclivity for and vulnerability to rewards and drugs of potential abuse.

    This study investigated adolescent and parent reports of adolescent social media use and its relation to adolescent psychosocial adjustment. The sample consisted of 226 participants (113 parent-adolescent dyads) from throughout the United States, with adolescents (55 males, 51 females, 7 unreported) ranging from ages 14 to 17. Parent and adolescent reports of the number of adolescents' social media accounts were moderately correlated with parent-reported DSM-5 symptoms of inattention, hyperactivity/impulsivity, ODD, anxiety, and depressive symptoms, as well as adolescent-reported fear of missing out (FoMO) and loneliness. Lastly, anxiety and depressive symptoms were highest among adolescents with a relatively high number of parent-reported social media accounts and relatively high FoMO. The implications of these findings and need for related longitudinal studies are discussed. Copyright © 2017 The Foundation for Professionals in Services for Adolescents. Published by Elsevier Ltd.

    Underage drinking is a prevalent risk behavior and common public health problem. Research shows that alcohol abuse not only affects the quality of life of drinkers themselves. The problems resulting from underage drinking pose substantial costs to society as well. The proposed study will address underage drinking with the use of an Internet campaign, which is a cost-effective way of tackling the problem. The aims of this study are to test the effectiveness of an online quiz competition in changing adolescents' alcohol-related attitudes and behavior and to explore the feasibility of using Internet viral marketing to reach a significant number of adolescents. The study will constitute a cluster randomized controlled trial for 20 secondary schools (6720 Grade 7-9 students). Schools will be randomized to intervention or control arm with equal likelihood. Students in intervention schools will be invited to take part in the Internet campaign, whereas those in control schools will receive relevant promotional leaflets. Alcohol-related attitude and behavior will be the primary outcome measures. The results of the proposed study will provide evidence on the efficacy of an Internet intervention in modifying adolescents' attitudes and behavior and guide further investigation into the prevention of and intervention in such risk behaviors as underage drinking. The project was funded July 2015, enrollment started September 2015, and results are expected July 2017. With the Internet increasingly being recognized as a practical and cost-effective platform for health information delivery, the proposed Internet-based intervention is expected to be more effective in altering adolescents' alcohol-related attitudes and behaviors than traditional health promotion.

    The paper deals with parental employment status and its relationship to adolescents' self-reported health. It studies the role of the financial situation, parent-adolescent relationship and adolescent resilience in the relationship between parental employment status and adolescents' self-rated health, vitality and mental health. Multiple regression analyses were used to analyse questionnaire data obtained from 2799 adolescents (mean age 14.3) in 2006. The results show a negative association of the father's, but not mother's unemployment or non-employment with adolescents' health. Regression analyses showed that neither financial strain nor a poor parent-adolescent relationship or a low score in resilience accounted for the relationship between the father's unemployment or non-employment and poorer adolescent health. Furthermore, resilience did not work as a buffer against the negative impact of fathers' unemployment on adolescents' health.

    The aim of this study was to explore physical self-concept of adolescents of the Western Balkans (Serbia, Slovenia, Croatia, and Bosnia and Herzegovina) according to sex and country. The participants were 2,606 students, ages 13 and 14 years (M = 13.5, SD = 0.9). The Physical Self-Description Questionnaire (PSDQ) was used to assess multidimensional physical self-concept. The results show the interaction of sex and country for three dimensions of physical self-concept (Appearance, Global Physical Self-Concept, and Self-Esteem). It was shown that female and male adolescents' perception of physical appearance, self-esteem, and global physical self-concept is more susceptible to influences of socio-cultural factors in the monitored countries. In all other dimensions of Physical self-concept, sex differences were consistently manifested in favour of male adolescents, except in Flexibility. Regardless of adolescents' sex, under the increasing influence of Western culture in the Western Balkan countries, adolescents more critically evaluate their body and motor abilities.

    Full Text Available Introduction: Depression is the most common psychiatric disorder that appears in adolescents. It has an adverse effect on physical as well as mental health. Many adolescents remain undiagnosed due to no accessibility to clinics. Objectives: To study demographic factors and their association with depression among adolescents of rural Maharashtra. Methods: A cross sectional study was conducted on 300 students (30 of either sex from 8th to 12th class. 6 item KADS (Kutcher Adolescent Depression Scale, BG Prasad’s modified socioeconomic scale and demographic data were collected from volunteers. Results: 6.66% of students were screened positive for depression by the scale. No statistical difference was found in number of students with depression with respect to sex, class and socioeconomic status. However the residence and type of family showed significant difference in number students of depression. Conclusion: the KADS is a good screening tool for depression and should be implemented for adolescents studying in rural areas for prevention and early treatment of depression.

    This study examined the longitudinal effects of adolescents' depressive symptoms on engagement in technology-based social comparison and feedback seeking (SCFS) behaviors. A total of 816 adolescents (54.7% girls; M age =14.1 at Time 1) participated at three times points, each one year apart. Adolescents reported technology-based SCFS, depressive symptoms, and frequencies of technology use (cell phones, Facebook, and Instagram). Multiple group (by gender) latent growth curve models examined concurrent and lagged effects of depressive symptoms on SCFS, controlling for adolescent's underlying trajectories of SCFS and overall frequencies of technology use. Results indicated that higher levels of depressive symptoms were concurrently associated with greater SCFS after accounting for adolescents' typical patterns of SCFS. For boys only, higher depressive symptoms were prospectively associated with later increases in SCFS. Results highlight the importance of social media as a unique context in which depressed adolescents may be at risk for maladaptive interpersonal behavior.

    Social relationships among adolescents with mental disorders are demanding. Adolescents with depressive symptoms may have few relationships and have difficulties sharing their problems. Internet may offer reliable and easy to use tool to collect real-time information from adolescents. The aim of this study is to explore how adolescents describe their social relationships with an electronic diary. Mixed methods were used to obtain a broad picture of adolescents' social relationships with the data gathered from network maps and reflective texts written in an electronic diary. Adolescents who visited an outpatient clinic and used an intervention (N=70) designed for adolescents with signs of depression were invited to use the electronic diary; 29 did so. The quantitative data gathered in the electronic diary were summarized with descriptive statistics, and the qualitative data were categorized using a thematic analysis with an inductive approach. We found that social relationships among adolescents with signs of depression can vary greatly in regards to the number of existing relationships (from lacking to 21) and the quality of the relationships (from trustful to difficult). However, the relationships may change, and the adolescents are also willing to build up their social relationships. Professionals need to be aware of the diversity of adolescents' social relationships and their need for personalized support.

    Child abuse is associated with obesity in adulthood through multiple mechanisms. However, little is known about the relationship between abuse and obesity during adolescence. The aim of this study was to investigate, using a birth cohort, whether there is an association between child abuse and overweight or obesity in adolescence. This study utilizes data from the Avon Longitudinal Study of Parents and Children, a prospective cohort study based in South West England. Using data from the 4205 children with complete data at 13 and 16 years, we analyzed body mass index (BMI) and anonymous parental report of abuse. Abuse was categorized as emotional, physical, or sexual. A sub-sample of 3429 had BMI recorded at 18 years, enabling a longitudinal analysis of BMI trajectories. Using linear and logistic regression analysis, adjusting for sex and family adversity, no association was found between child abuse and BMI, BMI Z-scores, overweight, or obesity, at 13 or 16 years, with all confidence intervals straddling the null. There was weak evidence of a negative association between physical and emotional abuse and BMI trajectories between 13 and 18 years. No relationship was found between child abuse and adolescent obesity in this cohort. This challenges the assumption that adolescent obesity is linked to previous child abuse, as demonstrated for obesity in adult life. A further longitudinal study utilizing both parental and child reports with data record linkage, to improve reporting of abuse, and including neglect as an abuse category, would be desirable.

    To obtain the self-concept psychological feature of cleft lip and palate (CLP) adolescents further and accurately, and offer reasons for timely and pointed psychological intervention. Based on the procedure and criteria of development of psychological questionnaire, a psychological questionnaire for CLP adolescents was designed. 93 CLP and 88 healthy adolescents were studied by using it and their half-quantified score raging 0-9 were analyzed statistically. (1) There was no statistical difference between CLP and normal adolescents, scored 5.91 and 5.66 respectively, which demonstrated that the self-concept of CLP adolescents was at a normal level without obvious passive tendency. (2) There was no significant difference between genders, but boys were more extroversion while girls did better on being unyielding and releasing strain. (3) CLP adolescents had a higher ability of psychological regulation and could face failure more bravely. CLP patients were in a tendency of protective behavior inhibition, companied less, and maximized delight mood unconsciously to decrease harm from enviroment. (4) CLP adolescents had a good parentage. (5) A majority of patients had low expectation of life-quality. (6) Much of CLP patients considered that speech was more important than appearance. Self-concept of CLP adolescents have normal self-concept and do better in psychological regulation and dependence than normal ones.

    People living in poverty have limited access to traditional financial institutions. Microfinance programmes are designed to meet this gap and show promise in improving income, economic productivity and health. Our Congolese-US community academic research partnership developed two livestock productive asset transfer programmes, Pigs for Peace (PFP) and Rabbits for Resilience (RFR), to address the interlinked health, social and economic well-being of individuals, their families and communities. The community-based randomised controlled trials examine the effectiveness of PFP and RFR to improve health, economic stability, and family and community relationships among male and female adults and adolescents living in 10 rural, postconflict villages of eastern Democratic Republic of Congo. PFP participants include adult permanent residents of rural villages; adolescent participants in RFR include male and female adolescents 10-15 years old living in the selected rural villages. Participants were randomised to intervention or delayed control group. Participants in PFP completed baseline interview prior to intervention and follow-up interview at 6, 12 and 18 months postintervention. In RFR, participants completed baseline interview prior to intervention and follow-up interview at 6, 12 and 18 months postbaseline. The primary outcome of both trials, the change in baseline mental health distress at 18 months in the intervention group (adults, adolescents) compared to control group, is used to calculate sample size. The Johns Hopkins Medical Institute Internal Review Board approved this protocol. A committee of respected Congolese educators and community members (due to lack of local ethics review board) approved the study. The findings will provide important information on the potential for community-led sustainable development initiatives to build on traditional livelihood (livestock raising, agriculture) to have a sustained health, economic and social impact on the

    Full Text Available The Study of Cardiovascular Risk in Adolescents (ERICA aims to estimate the prevalence of cardiovascular risk factors and metabolic syndrome in adolescents (12-17 years enrolled in public and private schools of the 273 municipalities with over 100,000 inhabitants in Brazil. The study population was stratified into 32 geographical strata (27 capitals and five sets with other municipalities in each macro-region of the country and a sample of 1,251 schools was selected with probability proportional to size. In each school three combinations of shift (morning and afternoon and grade were selected, and within each of these combinations, one class was selected. All eligible students in the selected classes were included in the study. The design sampling weights were calculated by the product of the reciprocals of the inclusion probabilities in each sampling stage, and were later calibrated considering the projections of the numbers of adolescents enrolled in schools located in the geographical strata by sex and age.

    In this longitudinal study, the relationships between perceived parenting characteristics and adolescent psychological well-being were examined in a sample of Hong Kong Chinese adolescents (N = 378). The results indicated that global parenting styles and specific parenting behaviors are concurrently related to hopelessness, life satisfaction, self-esteem, purpose in life, and general psychiatric morbidity at Time 1 and Time 2. Longitudinal and prospective analyses (Time 1 predictors of Time 2 criterion variables) suggested that the relations between parenting characteristics and adolescent psychological well-being are bidirectional in nature. The results indicated that the strengths of association between perceived parenting characteristics and adolescent psychological well-being are stronger in female than in male adolescents. Relative to maternal parenting characteristics, paternal parenting was found to exert a stronger influence on adolescent psychological well-being.

    Resilience is essential for the psychological adjustment of adolescents experiencing difficulty. Comparing differences in resilience between adolescent survivors of brain tumors and healthy adolescents may help identify factors related to resilience in adolescents. The purpose of this study was to clarify how illness impacts the normative development of adolescent survivors of brain tumors by comparing them to healthy adolescents in terms of resilience and how it is affected by various health problems. This cross-sectional, case-control study used convenience sampling to recruit 13- to 18-year-old adolescent survivors of brain tumors and healthy adolescents matched by school level, gender, and living area. Data were collected by structured questionnaires. The sample included 60 adolescent survivors and 120 healthy adolescents. Participants in both groups were predominantly male adolescents (63.3%) and junior high school students (55%). The 2 groups did not differ significantly in resilience, but survivors without emotional problems had a higher mean resilience score than did healthy adolescents and survivors with emotional problems (F = 8.65, P adolescent survivors of brain tumors and healthy adolescents. In addition, the impact of emotional problems on resilience was more severe in brain tumor survivors than in healthy adolescents. Our results suggest that pediatric oncology nurses design interdisciplinary school-based interventions to reduce the impact of emotional problems on resilience in both healthy adolescents and those who survived brain tumors.

    Implicit self-esteem has remained an active research topic in both the areas of implicit social cognition and self-esteem in recent decades. The purpose of this study is to explore the development of implicit self-esteem in adolescents. A total of 599 adolescents from junior and senior high schools in East China participated in the study. They ranged in age from 11 to 18 years with a mean age of 14.10 (SD = 2.16). The degree of implicit self-esteem was assessed using the Implicit Association Test (IAT) with the improved D score as the index. Participants also completed the Rosenberg Self-Esteem Scale (α = 0.77). For all surveyed ages, implicit self-esteem was positively biased, all ts>8.59, all psself-esteem and age was significant, r =  -.25, p = 1. 10(-10). A regression with implicit self-esteem as the criterion variable, and age, gender, and age × gender interaction as predictors further revealed the significant negative linear relationship between age and implicit self-esteem, β = -0.19, t = -3.20, p = 0.001. However, explicit self-esteem manifested a reverse "U" shape throughout adolescence. Implicit self-esteem in adolescence manifests a declining trend with increasing age, suggesting that it is sensitive to developmental or age-related changes. This finding enriches our understanding of the development of implicit social cognition.

    It is obvious that self-perception can play an important role in the development of self-management behaviours among adolescents with diabetes to promote their health and quality of life. This study seeks to explain self-perception in adolescents with diabetes. This qualitative study, which is of "grounded theory" type, was performed in 2013 in Ahvaz, Iran, through semi-structured interviews with ten adolescents with type 1 diabetes, two parents and a nurse, who were chosen objectively. Data analysis was performed using Strauss and Corbin 1998 method. Four main theme was obtained from the analysis of data, and the consequence theme was inferred as follows: getting insight (knowledge acquisition and belief management), perceiving similarities with others (not hiding the disease, showing the illness is normal, and accepting an active role in the family), and self-care management (independent control of food and treatment regimen and understanding of capabilities to manage the future of life and manage the daily activities of life), and life satisfaction (perception of being healthy and having a normal life). Getting insight into the disease is the most important part of perceiving similarities with others and offering self-care, which can provide a person's positive perception of himself/herself and the illness, as well as life satisfaction for their adolescent over time. These results are an operational guide for personnel providing health care services, especially diabetes specialist nurses.

    Full Text Available Purpose: Despite the growing evidence that ecological factors contribute to substance use, the relationship of ecological factors and illicit drugs such as marijuana use is not well understood, particularly among adolescents in Latin America. Guided by social disorganization and social stress theories, we prospectively examined the association of disaggregated neighborhood characteristics with marijuana use among adolescents in Santiago, Chile, and tested if these relationships varied by sex. Methods: Data for this study are from 725 community-dwelling adolescents participating in the Santiago Longitudinal Study, a study of substance using behaviors among urban adolescents in Santiago, Chile. Adolescents completed a two-hour interviewer administered questionnaire with questions about drug use and factors related to drug using behaviors. Results: As the neighborhood levels of drug availability at baseline increased, but not crime or noxious environment, adolescents had higher odds of occasions of marijuana use at follow up, approximately 2 years later (odds ratio [OR] = 1.39; 95% CI = 1.16–1.66, even after controlling for the study’s covariates. No interactions by sex were significant. Discussion: The findings suggest that “poverty”, “crime”, and “drug problems” may not be synonyms and thus can be understood discretely. As Latin American countries re-examine their drug policies, especially those concerning decriminalizing marijuana use, the findings suggest that attempts to reduce adolescent marijuana use in disadvantaged neighborhoods may do best if efforts are concentrated on specific features of the “substance abuse environment”.

    To explore the potential benefits and challenges of involving adolescents in the education of medical students and residents from the perspectives of adolescents who are hospitalized with chronic health conditions. We conducted qualitative interviews with adolescents at a Canadian pediatric hospital. Eligible participants were those between 13-18 years of age, with chronic health conditions lasting more than three months who were feeling well enough to participate in an interview. We used conventional content analysis to analyze the data. Sixteen adolescents participated in the study. In terms of benefits, the participants described how involving adolescents in the education of medical students and residents would improve patient-physician interactions, increase patients' confidence and self-worth, encourage patients to self-reflect and gain knowledge about their health conditions and themselves, as well as enable patients to socialize with other patients. When asked about the challenges, the participants discussed how it might be difficult to include diverse patient perspectives, manage adolescents' negativity, and ensure that learners are non-judgmental towards adolescents and take them seriously. While many of the reported benefits and challenges correspond with those featured in the literature on adult patient involvement in medical education, our findings underscore the distinctive benefits and challenges that medical educators may experience in designing and implementing educational initiatives that involve adolescents. Through the future design and implementation of educational initiatives, it is important to further explore the benefits and challenges of such adolescent involvement, as we know that adolescents can be valuable contributors to medical education.

    The standard definition for protocol adherence is the proportion of all scheduled doses that are delivered. In clinical research, this definition has several limitations when evaluating protocol adherence in trials that study interventions requiring continuous titration. Building upon a specific case study, we analyzed a recent trial of a continuously titrated intervention to assess the impact of different definitions of protocol deviations on the interpretation of protocol adherence. The OVATION pilot trial was an open-label randomized controlled trial of higher (75-80 mmHg) versus lower (60-65 mmHg) mean arterial pressure (MAP) targets for vasopressor therapy in shock. In this trial, potential protocol deviations were defined as MAP values outside the targeted range for >4 consecutive hours during vasopressor therapy without synchronous and consistent adjustments of vasopressor doses. An adjudication committee reviewed each potential deviation to determine if it was clinically-justified or not. There are four reasons for this contextual measurement and reporting of protocol adherence. First, between-arm separation is a robust measure of adherence to complex protocols. Second, adherence assessed by protocol deviations varies in function of the definition of deviations and the frequency of measurements. Third, distinguishing clinically-justified vs. not clinically-justified protocol deviations acknowledges clinically sensible bedside decision-making and offers a clear terminology before the trial begins. Finally, multiple metrics exist to report protocol deviations, which provides different information but complementary information on protocol adherence. In trials of interventions requiring continuous titration, metrics used for defining protocol deviations have a considerable impact on the interpretation of protocol adherence. Definitions for protocol deviations should be prespecified and correlated with between-arm separation, if it can be measured.

    In recent years, suicide in children and adolescents has increased considerably, becoming the second cause of death in this age group. Therefore, the aim of this study was to identify characteristics and factors that could precipitate deaths by suicide in children and adolescents. Using the psychological autopsy method, we studied 28 suicide cases of children and adolescents between 10 and 17 years old. Socio-demographic factors, characteristics of the suicide and family history were documented. The proportion of deaths by suicide was the same in females and males (50% each). Most of the suicides were performed at the child/adolescent's home (78.6%) and no history of previous suicide attempts were registered (85.7%). Also, the majority of suicidal individuals came from a dysfunctional family (60.7%). Our results identified characteristics of children and adolescents that had died by suicide, such as dying at their homes and coming from dysfunctional families. Knowing the characteristics of children and adolescents that had ended their lives by suicide should be considered in future studies to help developing preventive programs and strategies for treating suicidal behaviors in Mexican children and adolescents.

    Obesity is a chronic disease which causes medical and psychiatric complications. Family climate is also a critical factor in the presence and treatment of obesity and comorbid psychiatric disorders. In our study, perceived expressed emotion (EE), psychopathology, self-esteem and emotional and behavioural problems among obese adolescents will be investigated by comparison with their non-obese peers. This study was carried out with 49 obese adolescents and 47 non-obese adolescents as a control group. All participants were requested to fill out the Socio-demographic Data Form, Shortened Level of Expressed Emotion Scale, Rosenberg Self-Esteem Scale, Strength and Difficulties Questionnaire-Adolescent Form. In our study, obese adolescents showed a significant difference in perceived EE (pself-esteem (pself esteem. A higher rate of perceived EE, psychopathology and low self-esteem among obese adolescents showed that obesity prevention and treatment are also crucial for mental health in adolescents. With the help of our study results, we aimed to emphasize the role of the family in obese adolescent's mental health and their treatment. By the help of our results we try to identifying risk factors in childhood that promote obesity in order to help develop targeted intervention and prevention programs.

    To investigate the planning of subgroup analyses in protocols of randomised controlled trials and the agreement with corresponding full journal publications. Cohort of protocols of randomised controlled trial and subsequent full journal publications. Six research ethics committees in Switzerland, Germany, and Canada. 894 protocols of randomised controlled trial involving patients approved by participating research ethics committees between 2000 and 2003 and 515 subsequent full journal publications. Of 894 protocols of randomised controlled trials, 252 (28.2%) included one or more planned subgroup analyses. Of those, 17 (6.7%) provided a clear hypothesis for at least one subgroup analysis, 10 (4.0%) anticipated the direction of a subgroup effect, and 87 (34.5%) planned a statistical test for interaction. Industry sponsored trials more often planned subgroup analyses compared with investigator sponsored trials (195/551 (35.4%) v 57/343 (16.6%), P<0.001). Of 515 identified journal publications, 246 (47.8%) reported at least one subgroup analysis. In 81 (32.9%) of the 246 publications reporting subgroup analyses, authors stated that subgroup analyses were prespecified, but this was not supported by 28 (34.6%) corresponding protocols. In 86 publications, authors claimed a subgroup effect, but only 36 (41.9%) corresponding protocols reported a planned subgroup analysis. Subgroup analyses are insufficiently described in the protocols of randomised controlled trials submitted to research ethics committees, and investigators rarely specify the anticipated direction of subgroup effects. More than one third of statements in publications of randomised controlled trials about subgroup prespecification had no documentation in the corresponding protocols. Definitive judgments regarding credibility of claimed subgroup effects are not possible without access to protocols and analysis plans of randomised controlled trials. © The DISCO study group 2014.

    Evidence-based outpatient psychotherapeutic programs are first-line treatment of borderline personality disorder (BPD). Early and effective treatment of BPD is crucial to the prevention of its individual, psychosocial, and economic consequences. However, in spite of recent advantages in diagnosing adolescent BPD, there is a lack of cost-effective evidence-based treatment programs for adolescents. Mentalization-based treatment is an evidence-based program for BPD, originally developed for adults. We will investigate whether a specifically designed mentalization-based treatment in groups is an efficacious treatment for adolescents with BPD or subthreshold BPD compared to treatment as usual. The trial is a four-center, two-armed, parallel-group, assessor-blinded randomized clinical superiority trial. One hundred twelve patients aged 14 to 17 referred to Child and Adolescent Psychiatric Clinics in Region Zealand are randomized to 1 year of either mentalization-based treatment in groups or treatment as usual. Patients will be included if they meet at least four DSM-5 criteria for BPD. The primary outcome is self-reported borderline features at discharge. Secondary outcomes will include self-harm, depression, BPD criteria, externalizing and internalizing symptoms, and social functioning, together with parental reports on borderline features, externalizing and internalizing symptoms. Measures of attachment and mentalization will be included as mediational variables. Follow-up assessment will take place at 3 and 12 months after end of treatment. This is the first randomized controlled trial to test the efficacy of a group-based mentalization-based treatment for adolescents with BPD or subthreshold BPD. If the results confirm our hypothesis, this trial will add to the treatment options of cost-effective treatment of adolescent BPD. Clinicaltrials.gov NCT02068326 , February 19, 2014.

    The concept of the risk-based approach has been introduced as an effort to secure the quality of clinical trials. In the risk-based approach, identification and evaluation of risk in advance are considered important. For recently completed clinical trials, we investigated the relationship between study characteristics and protocol deviations leading to the exclusion of subjects from Per Protocol Set (PPS) efficacy analysis. New drugs approved in Japan in the fiscal year 2014-2015 were targeted in the research. The reasons for excluding subjects from the PPS efficacy analysis were described in 102 trials out of 492 in the summary of new drug application documents, which was publicly disclosed after the drug's regulatory approval. The author extracted these reasons along with the numbers of the cases and the study characteristics of each clinical trial. Then, the direct comparison, univariate regression analysis, and multivariate regression analysis was carried out based on the exclusion rate. The study characteristics for which exclusion of subjects from the PPS efficacy analysis were frequently observed was multiregional clinical trials in study region; inhalant and external use in administration route; Anti-infective for systemic use; Respiratory system, Dermatologicals, and Nervous system in therapeutic drug under the Anatomical Therapeutic Chemical Classification. In the multivariate regression analysis, the clinical trial variables of inhalant, Respiratory system, or Dermatologicals were selected as study characteristics leading to a higher exclusion rate. The characteristics of the clinical trial that is likely to cause protocol deviations that will affect efficacy analysis were suggested. These studies should be considered for specific attention and priority observation in the trial protocol or its monitoring plan and execution, such as a clear description of inclusion/exclusion criteria in the protocol, development of training materials to site staff, and

    The main objective of this prospective longitudinal study was to investigate bidirectional associations between adolescent cannabis use (CU) and neurocognitive performance in a community sample of 294 young men from ages 13 to 20 years. The results showed that in early adolescence, and prior to initiation to CU, poor short-term and working memory, but high verbal IQ, were associated with earlier age of onset of CU. In turn, age of CU onset and CU frequency across adolescence were associated with (a) specific neurocognitive decline in verbal IQ and executive function tasks tapping trial and error learning and reward processing by early adulthood and (b) lower rates of high-school graduation. The association between CU onset and change in neurocognitive function, however, was found to be accounted for by CU frequency. Whereas the link between CU frequency across adolescence and change in verbal IQ was explained (mediated) by high school graduation, the link between CU frequency and tasks tapping trial and error learning were independent from high school graduation, concurrent cannabis and other substance use, adolescent alcohol use, and externalizing behaviors. Findings support prevention efforts aimed at delaying onset and reducing frequency of CU.

  7. Postural strategies and sensory integration: no turning point between childhood and adolescence.

    Directory of Open Access Journals (Sweden)

    Sophie Mallau

    Full Text Available In this study, we investigated the sensory integration to postural control in children and adolescents from 5 to 15 years of age. We adopted the working hypothesis that considerable body changes occurring during these periods may lead subjects to under-use the information provided by the proprioceptive pathway and over-use other sensory systems such as vision to control their orientation and stabilize their body. It was proposed to determine which maturational differences may exist between the sensory integration used by children and adolescents in order to test the hypothesis that adolescence may constitute a specific phase in the development of postural control. This hypothesis was tested by applying an original protocol of slow oscillations below the detection threshold of the vestibular canal system, which mainly serves to mediate proprioceptive information, to the platform on which the subjects were standing. We highlighted the process of acquiring an accurate sensory and anatomical reference frame for functional movement. We asked children and adolescents to maintain a vertical stance while slow sinusoidal oscillations in the frontal plane were applied to the support at 0.01 Hz (below the detection threshold of the semicircular canal system and at 0.06 Hz (above the detection threshold of the semicircular canal system with their eyes either open or closed. This developmental study provided evidence that there are mild differences in the quality of sensory integration relative to postural control in children and adolescents. The results reported here confirmed the predominance of vision and the gradual mastery of somatosensory integration in postural control during a large period of ontogenesis including childhood and adolescence. The youngest as well as the oldest subjects adopted similar qualitative damping and segmental stabilization strategies that gradually improved with age without reaching an adult's level. Lastly, sensory

    Deep transcranial magnetic stimulation (TMS) with an H-1 coil was recently approved by the U.S. Food and Drug Administration (U.S. FDA) for treatment-resistant depression (TRD) in adults. Studies assessing the safety and effectiveness of deep TMS in adolescent TRD are lacking. The purpose of this brief report is to provide a case history of an adolescent enrolled in an investigational deep TMS protocol. A case history is described of the first participant of a sham-controlled clinical trial who had a seizure in the course of deep TMS with parameter settings extrapolated from the adult studies that led to US FDA approval (H-1 coil, 120% target stimulation intensity, 18 Hz, 55 trains of 2-second duration, total 1980 pulses). The participant was a 17-year-old unmedicated female, with no significant medical history and no history of seizures or of drug or alcohol use. Brain magnetic resonance imaging showed no structural abnormalities. She initially received sham, which was well tolerated. During active treatment sessions, titration began at 85% of motor threshold (MT) and increased by 5% per day. Her weekly MT measurements were stable. On her first day of 120% MT (8th active treatment), during the 48th train, the participant had a generalized, tonic-clonic seizure that lasted 90 seconds and resolved spontaneously. She had an emergency medicine evaluation and was discharged home without anticonvulsant medications. There were no further seizures reported at a 6-month follow-up. We report a deep TMS-induced generalized tonic-clonic seizure in an adolescent with TRD participating in a clinical trial. Given the demonstrated benefits of deep TMS for adult TRD, research investigating its use in adolescents with TRD is an important area. However, in light of this experience, additional precautions for adolescents should be considered. We propose that further dose-finding investigations are needed to refine adolescent-specific parameters that may be safe and effective for

    Full Text Available Abstract Background Despite extensive use of self-rated health questions in youth studies, little is known about what such questions capture among adolescents. Hence, the aim of this study was to explore how adolescents interpret and reason when answering a question about self-rated health. Methods A qualitative study using think-aloud interviews explored the question, “How do you feel most of the time?”, using five response options (“Very good”, “Rather good”, “Neither good, nor bad”, “Rather bad”, and “Very bad”. The study involved 58 adolescents (29 boys and 29 girls in lower secondary school (7th grade and upper secondary school (12th grade in Sweden. Results Respondents’ interpretations of the question about how they felt included social, mental, and physical aspects. Gender differences were found primarily in that girls emphasized stressors, while age differences were reflected mainly in the older respondents’ inclusion of a wider variety of influences on their assessments. The five response options all demonstrated differences in self-rated health, and the respondents’ understanding of the middle option, “Neither good, nor bad”, varied widely. In the answering of potential sensitive survey questions, rationales for providing honest or biased answers were described. Conclusions The use of a self-rated health question including the word ‘feel’ captured a holistic view of health among adolescents. Differences amongst response options should be acknowledged when analyzing self-rated health questions. If anonymity is not feasible when answering questions on self-rated health, a high level of privacy is recommended to increase the likelihood of reliability.

    We compared the level of attention capacity between adolescents from the center and south of Europe. The study included 627 European adolescents (54% girls), aged 12.5-17.5 years, who participated in the HELENA Study. The d2 Test of Attention was administered to assess attention capacity. The main results showed that adolescents from the south of Europe had significantly higher score in attention capacity compared with adolescents from central Europe (score + 8.1; 95%CI, 2.44-13.61) after adjustment for age, sex, socioeconomic indicators, body mass index, cardiorespiratory fitness and diet quality index (p = 0.012). Adolescents from the south of Europe had higher levels of attention capacity than their counterparts from central Europe independently of sociodemographic and health-related factors. These differences should be taken into account by educational institutions when promoting new approaches for putting into the practice student's capacities. What is Known? • Attention is a crucial capacity during adolescence. • Several health-related factors (i.e., physical activity, fitness or fatness) may influence attention capacity in adolescents. What is New? • Adolescents from the south of Europe had higher levels of attention capacity than their counterparts from the center, after accounting for socioeconomic factors, fitness, fatness and quality of diet. • These differences should be taken into account by educational institutions when promoting new approaches for putting into the practice student's capacities.

    Caffeinated products are widely available to adolescents, and consumption of caffeine products-energy drinks and coffee in particular-is on the rise in this age group (Branum, Rossen, & Schoendorf, 2014). Yet, little is known about the psychosocial context of caffeine use. Previous studies on adolescent caffeine use have focused on caffeine's acute physiological effects, rather than the psychosocial contexts and beliefs regarding different types of caffeinated beverages (e.g., coffee, energy drinks, soda). The current research examines the contexts and beliefs associated with adolescents' use of caffeinated beverages (e.g., coffee, energy drinks, soda) using a focus group approach. Eleven focus group interviews (49 total participants) addressed adolescents' motivations for and patterns of caffeine use; they were transcribed and axial coding was used to identify common themes. Coffee and energy drinks were perceived to be the most popular caffeinated beverages. Reasons for consuming caffeine included the effect of caffeine as a stimulant, the pleasant feelings experienced when drinking it, and the fact that caffeine was available. As for contexts, coffee was consumed in more diverse social contexts than other caffeinated beverages. Friends and sports were the most popular contexts for energy drink use. The present findings inform adolescent health promotion efforts and provide researchers and practitioners alike detailed information in adolescents' own words about how and why they use caffeine. Adolescents' beliefs about caffeinated products are not uniform; the reasons adolescents articulate regarding their use of coffee, soda, and energy drinks are different across contexts and beverage type.

    Today, due to developing communicative technologies, computer games and other audio-visual media as social phenomena, are very attractive and have a great effect on children and adolescents. The increasing popularity of these games among children and adolescents results in the public uncertainties about plausible harmful effects of these games. This study aimed to investigate the correlation between computer games and behavioral problems on male guidance school students. This was a descriptive-correlative study on 384 randomly chosen male guidance school students. They were asked to answer the researcher's questionnaire about computer games and Achenbach's Youth Self-Report (YSR). The Results of this study indicated that there was about 95% direct significant correlation between the amount of playing games among adolescents and anxiety/depression, withdrawn/depression, rule-breaking behaviors, aggression, and social problems. However, there was no statistically significant correlation between the amount of computer game usage and physical complaints, thinking problems, and attention problems. In addition, there was a significant correlation between the students' place of living and their parents' job, and using computer games. Computer games lead to anxiety, depression, withdrawal, rule-breaking behavior, aggression, and social problems in adolescents.

    Occupational therapy can contribute to sexual and reproductive health through health education. The purpose of this study was to describe an occupational therapy intervention aimed at sexual and reproductive health promotion in adolescents. Fifty-eight adolescents were involved in the study, before, during and after the interventions. Educative activities such as puzzles, storytelling, mime and board games were used, which occupational therapy faculty and students had constructed. The games were employed as mediators for gaining knowledge in sexual and reproductive health. Outcome was measured using a questionnaire, audio recordings and field diaries. The data were analysed by descriptive statistics and thematic content analysis. The results showed the adolescents' increased knowledge of sexual and reproductive health information immediately after the intervention. The thematic analysis was grouped into three categories: the adolescents' initial expectations regarding the project, reflections on the process experienced during the interventions and use of educational games by occupational therapists. The importance of rapport and dialogue was highlighted in the construction of interventions based on participatory methods. The absence of a longitudinal follow-up is a limitation in this study. Further research is important to systematically assess sexual health promotion strategies in adolescence. Copyright © 2015 John Wiley & Sons, Ltd.

    Symptomatic spondylolysis is a stress reaction caused by microtrauma during physical exercise, an imaging diagnostic subgroup of Adolescent Low Back Pain (ALBP), found in adolescent athletes. Early diagnosis increases the possibility of healing. Thus, it is important to divide ALBP into subgroups. The aim of this study was to evaluate clinical tests that can distinguish symptomatic spondylolysis from other forms of ALBP in order to facilitate early referral for diagnostic imaging. The investigation subjects were a prospective case series with a control group, 25 subjects with ALBP and 13 subjects that had no history of LBP. The 2 groups were examined using the same clinical protocol. MRI of the whole lumbar spine was performed in both the case and control groups and CT investigations of the L4 and L5 vertebrae were performed in the case group. Significant differences between the 2 groups were found in 8 of our clinical tests. No clinical test, alone or in combination, could distinguish between spondylolysis and other forms of ALBP. As 88% of the subjects in the case group had MRI findings and almost 50% had spondylolysis, MRI should be performed at an early age in young athletes with ALBP. © Georg Thieme Verlag KG Stuttgart · New York.

This was a cross-sectional study involving probabilistic samples of 3,015 and 3,020 adolescents in surveys conducted in 2006-2007 and 2010, respectively. The International Study of Asthma and Allergies in Childhood protocol was used on both occasions. Comparing the two periods, there were no significant differences regarding cumulative wheezing, active asthma, four or more wheezing attacks within the last year, sleep disturbed by wheezing more than one night per week, and speech-limiting wheezing. The prevalences of exercise-induced wheezing, dry cough at night, and physician-diagnosed asthma were significantly higher in 2010 than in the 2006-2007 period (p school students than in public school students (p school students.

    Studies examining economic hardship consistently have linked family economic hardship to adolescent adjustment via parent and family functioning, but limited attention has been given to adolescents' perceptions of these processes. To address this, the authors investigated the intervening effects of adolescents' perceptions of economic hardship and of parent-adolescent warmth and conflict on the associations between parental economic hardship and adolescent adjustment (i.e., depressive symptoms, risky behaviors, and school performance) in a sample of 246 Mexican-origin families. Findings revealed that both mothers' and fathers' reports of economic hardship were positively related to adolescents' reports of economic hardship, which in turn, were negatively related to parent-adolescent warmth and positively related to parent-adolescent conflict with both mothers and fathers. Adolescents' perceptions of economic hardship were indirectly related to (a) depressive symptoms through warmth with mothers and conflict with mothers and fathers, (b) involvement in risky behaviors through conflict with mothers and fathers, and (c) GPA through conflict with fathers. Our findings highlight the importance of adolescents' perceptions of family economic hardship and relationships with mothers and fathers in predicting adolescent adjustment.

    Attention-deficit/hyperactivity disorder (ADHD) affects functioning of the family, decreasing interactions and loyalty and increasing conflict between adolescents with ADHD and their families. Irritable mood and difficulties with emotional dysregulation are common in children with ADHD. The objective of the current study was to assess levels of irritability in adolescents with ADHD using self- and parent-report scales, and investigate the relationship between irritability levels and parental attitudes. A total of 47 adolescents with ADHD and 39 adolescents with typical development participated in the current study. Findings demonstrated that higher levels of parent-reported irritability were associated with decreased egalitarian attitudes in the ADHD group. Although other parental attitudes were not associated with self- and parent-reported irritability, evaluation of the relationship between parental attitudes and irritability in adolescents with ADHD, which can guide diagnosis and treatment of ADHD, is of critical importance.

    The results of stress myocardial perfusion SPECT could be enhanced by new cadmium-zinc-telluride (CZT) cameras, although differences compared to the results with conventional Anger cameras remain poorly known for most study protocols. This study was aimed at comparing the results of CZT and Anger SPECT according to various study protocols while taking into account the influence of obesity. The study population, which was from three different institutions equipped with identical CZT cameras, comprised 276 patients referred for study using protocols involving 201 Tl (n = 120) or 99m Tc-sestamibi injected at low dose at stress ( 99m Tc-Low; stress/rest 1-day protocol; n = 110) or at high dose at stress ( 99m Tc-High; rest/stress 1-day or 2-day protocol; n = 46). Each Anger SPECT scan was followed by a high-speed CZT SPECT scan (2 to 4 min). Agreement rates between CZT and Anger SPECT were good irrespective of the study protocol (for abnormal SPECT, 201 Tl 92 %, 99m Tc-Low 86 %, 99m Tc-High 98 %), although quality scores were much higher for CZT SPECT with all study protocols. Overall correlations were high for the extent of myocardial infarction (r = 0.80) and a little lower for ischaemic areas (r = 0.72), the latter being larger on Anger SPECT (p 201 Tl or 99m Tc-Low group and in whom stress myocardial counts were particularly low with Anger SPECT (228 ± 101 kcounts) and dramatically enhanced with CZT SPECT (+279 ± 251 %). Concordance between the results of CZT and Anger SPECT is good regardless of study protocol and especially when excluding obese patients who have low-count Anger SPECT and for whom myocardial counts are dramatically enhanced on CZT SPECT.

    Full Text Available Group key management is an important functional building block for secure multicast architecture. Thereby, it has been extensively studied in the literature. The main proposed protocol is Adaptive Clustering for Scalable Group Key Management (ASGK. According to ASGK protocol, the multicast group is divided into clusters, where each cluster consists of areas of members. Each cluster uses its own Traffic Encryption Key (TEK. These clusters are updated periodically depending on the dynamism of the members during the secure session. The modified protocol has been proposed based on ASGK with some modifications to balance the number of affected members and the encryption/decryption overhead with any number of the areas when a member joins or leaves the group. This modified protocol is called Ancestors protocol. According to Ancestors protocol, every area receives the dynamism of the members from its parents. The main objective of the modified protocol is to reduce the number of affected members during the leaving and joining members, then 1 affects n overhead would be reduced. A comparative study has been done between ASGK protocol and the modified protocol. According to the comparative results, it found that the modified protocol is always outperforming the ASGK protocol.

    Full Text Available Abstract Background The standard definition for protocol adherence is the proportion of all scheduled doses that are delivered. In clinical research, this definition has several limitations when evaluating protocol adherence in trials that study interventions requiring continuous titration. Discussion Building upon a specific case study, we analyzed a recent trial of a continuously titrated intervention to assess the impact of different definitions of protocol deviations on the interpretation of protocol adherence. The OVATION pilot trial was an open-label randomized controlled trial of higher (75–80 mmHg versus lower (60–65 mmHg mean arterial pressure (MAP targets for vasopressor therapy in shock. In this trial, potential protocol deviations were defined as MAP values outside the targeted range for >4 consecutive hours during vasopressor therapy without synchronous and consistent adjustments of vasopressor doses. An adjudication committee reviewed each potential deviation to determine if it was clinically-justified or not. There are four reasons for this contextual measurement and reporting of protocol adherence. First, between-arm separation is a robust measure of adherence to complex protocols. Second, adherence assessed by protocol deviations varies in function of the definition of deviations and the frequency of measurements. Third, distinguishing clinically-justified vs. not clinically-justified protocol deviations acknowledges clinically sensible bedside decision-making and offers a clear terminology before the trial begins. Finally, multiple metrics exist to report protocol deviations, which provides different information but complementary information on protocol adherence. Conclusions In trials of interventions requiring continuous titration, metrics used for defining protocol deviations have a considerable impact on the interpretation of protocol adherence. Definitions for protocol deviations should be prespecified and correlated

    Objective To determine whether adolescents who self-harm are at increased risk of heavy and dependent substance use in adulthood. Method Fifteen-year prospective cohort study of a random sample of 1943 adolescents recruited from secondary schools across the state of Victoria, Australia. Data pertaining to self-harm and substance use was obtained at seven waves of follow-up, from mean age 15.9 years to mean age 29.1 years. Results Substance use and self-harm were strongly associated during the adolescent years (odds ratio (OR): 3.3, 95% CI 2.1–5.0). Moreover, adolescent self-harmers were at increased risk of substance use and dependence syndromes in young adulthood. Self-harm predicted a four-fold increase in the odds of multiple dependence syndromes (sex- and wave-adjusted OR: 4.2, 95% CI: 2.7–6.6). Adjustment for adolescent anxiety/depression attenuated but did not eliminate most associations. Adolescent substance use confounded all associations, with the exception of multiple dependence syndromes, which remained robustly associated with adolescent self-harm (fully adjusted odds ratio: 2.0, 95% CI: 1.2–3.2). Conclusion Adolescent self-harm is an independent risk factor for multiple dependence syndromes in adulthood. This level of substance misuse is likely to contribute substantially to the premature mortality and disease burden experienced by individuals who self-harm. PMID:24954250

    Objective To assess whether exposure to movie smoking is associated with cigarette smoking among Argentinian adolescents. Study design School-based longitudinal study involving 33 secondary schools in Argentina. The sample included 2502 never smokers (average age at entry =12.5y), 1,700 (67.9%) of whom completed follow-up surveys 17 months later. Exposure to the top 100 grossing films for each year between 2009 and 2013 was assessed by content-coding films for tobacco, and then asking adolescents whether they had seen each of 50 titles, randomly selected from the larger pool, then parsing exposure into tertiles. Logistic regression models estimated adjusted odds ratio (AOR) for the following transitions: non-susceptible to susceptible never smoker, never smoker to ever smoker, and never smoker to current smoking (last 30 days). Results At follow-up, 34.4% of non-susceptible never smokers became susceptible, 24.1% reported having tried smoking, and 9.6% were current smokers. Most exposure to movie smoking was from US-produced films (average 60.3 minutes compared with only 3.4 minutes from Argentine films). Higher exposure to smoking in movies was significantly associated with increased odds of becoming susceptible (AOR1st vs 3rd tertile = 1.77, 95% confidence interval 1.30–2.41), of trying smoking (AOR1st vs 3rd tertile = 1.54, 1.14–2.08), and marginally associated with current smoking (AOR1st vs 3rd tertile = 1.54, 0.99–2.40). Exposure to smoking in US- or Argentine-produced films had similar associations. Conclusion In Argentina, exposure to smoking in the movies predicted future smoking transitions among early adolescents, with most exposure coming from viewing US movies. PMID:28029343

    Studies using animal models of adolescent exposure to alcohol, nicotine, cannabinoids, and the stimulants cocaine, 3,4-Methylenedioxymethampethamine and methamphetamine have revealed a variety of persisting neural and behavioral consequences. Affected brain regions often include mesolimbic and prefrontal regions undergoing notable ontogenetic change during adolescence, although it is unclear whether this represents areas of specific vulnerability or particular scrutiny to date. Persisting alterations in forebrain systems critical for modulating reward, socioemotional processing and cognition have emerged, including apparent induction of a hyper-dopaminergic state with some drugs and/or attenuations in neurons expressing cholinergic markers. Disruptions in cognitive functions such as working memory, alterations in affect including increases in social anxiety, and mixed evidence for increases in later drug self-administration have also been reported. When consequences of adolescent and adult exposure were compared, adolescents were generally found to be more vulnerable to alcohol, nicotine, and cannabinoids, but generally not to stimulants. More work is needed to determine how adolescent drug exposure influences sculpting of the adolescent brain, and provide approaches to prevent/reverse these effects. PMID:27484868

    Many studies rely on self-reports to capture population trends and trajectories in weight gain over adulthood, but the validity of self-reports is often considered a limitation. The purpose of this work was to examine long-term trajectories of self-reporting bias in a national sample of American youth. With 3 waves of data from the National Longitudinal Study of Adolescent Health (1996-2008), we used growth curve models to examine self-reporting bias in trajectories of weight gain across adolescence and early adulthood (ages 13-32 years). We investigated whether self-reporting bias is constant over time, or whether adolescents become more accurate in reporting their weight as they move into young adulthood, and we examined differences in self-reporting bias by sex, race/ethnicity, and attained education. Adolescent girls underreported their weight by 0.86 kg on average, and this rate of underreporting increased over early adulthood. In contrast, we found no evidence that boys underreported their weight either in adolescence or over the early adult years. For young men, self-reports of weight were unbiased estimates of measured weight among all racial/ethnic and educational subpopulations over adolescence and early adulthood. © The Author 2014.

    Reported cases of child maltreatment are increasing in Taiwan. Yet, comprehensive epidemiological characteristics of adolescents' exposure over the wide spectrum of violence are still lacking. The purpose of this study was to estimate the prevalence and magnitude of child maltreatment among Taiwanese adolescents. A population-based study was conducted with 5,276 adolescents aged 12-18 from 35 schools in 17 cities and townships to determine the prevalence of five forms of child maltreatment in Taiwan. A total of 5,236 adolescents completed anonymous, self-report, structured questionnaires. Most adolescents (91%, n=4,788) experienced at least one form of maltreatment with 83% (n=4,347) exposed during the previous year. Violence exposure was the most common type of child maltreatment experienced, followed by psychological abuse, physical abuse, neglect, and sexual abuse. Adolescents reported an average of 7.4 (SD=5.87) victimizations over their lifetime and 4.8 (SD=4.82) victimizations during the past year. Females reported a higher rate of neglect, while males reported a higher rate of sexual abuse. Most of the sexual abuse perpetrators were known by their victims. Adolescents' victimization and polyvictimization from child maltreatment in Taiwan deserves a review and modification of national control and prevention policies. Copyright © 2014 The Authors.

    Adolescence is a peculiar age mainly characterized by physical and psychological changes that may affect the perception of one's own and others' body. This perceptual peculiarity may influence the way in which bottom-up and top-down processes interact and, consequently, the perception and evaluation of art. This study is aimed at investigating, by means of the eye-tracking technique, the visual explorative behavior of adolescents while looking at paintings. Sixteen color paintings, categorized as dynamic and static, were presented to twenty adolescents; half of the images represented natural environments and half human individuals; all stimuli were displayed under aesthetic and movement judgment tasks. Participants' ratings revealed that, generally, nature images are explicitly evaluated as more appealing than human images. Eye movement data, on the other hand, showed that the human body exerts a strong power in orienting and attracting visual attention and that, in adolescence, it plays a fundamental role during aesthetic experience. In particular, adolescents seem to approach human-content images by giving priority to elements calling forth movement and action, supporting the embodiment theory of aesthetic perception.

    Background The increased use and costs of specialist child and adolescent mental health services (MHS) urge us to assess the effectiveness of these services. The aim of this paper is to compare the course of emotional and behavioural problems in adolescents with and without MHS use in a naturalistic setting. Method and Findings Participants are 2230 (pre)adolescents that enrolled in a prospective cohort study, the TRacking Adolescents' Individual Lives Survey (TRAILS). Response rate was 76%, mean age at baseline 11.09 (SD 0.56), 50.8% girls. We used data from the first three assessment waves, covering a six year period. Multiple linear regression analysis, propensity score matching, and data validation were used to compare the course of emotional and behavioural problems of adolescents with and without MHS use. The association between MHS and follow-up problem score (β 0.20, SE 0.03, p-value<0.001) was not confounded by baseline severity, markers of adolescent vulnerability or resilience nor stressful life events. The propensity score matching strategy revealed that follow-up problem scores of non-MHS-users decreased while the problem scores of MHS users remained high. When taking into account future MHS (non)use, it appeared that problem scores decreased with limited MHS use, albeit not as much as without any MHS use, and that problem scores with continuous MHS use remained high. Data validation showed that using a different outcome measure, multiple assessment waves and multiple imputation of missing values did not alter the results. A limitation of the study is that, although we know what type of MHS participants used, and during which period, we lack information on the duration of the treatment. Conclusions The benefits of MHS are questionable. Replication studies should reveal whether a critical examination of everyday care is necessary or an artefact is responsible for these results.

  20. Adolescent alcohol exposure: Are there separable vulnerable periods within adolescence?

    Science.gov (United States)

    Spear, Linda Patia

    2015-09-01

    There are two key alcohol use patterns among human adolescents that confer increased vulnerability for later alcohol abuse/dependence, along with neurocognitive alterations: (a) early initiation of use during adolescence, and (b) high rates of binge drinking that are particularly prevalent late in adolescence. The central thesis of this review is that lasting neurobehavioral outcomes of these two adolescent exposure patterns may differ. Although it is difficult to disentangle consequences of early use from later binge drinking in human studies given the substantial overlap between groups, these two types of problematic adolescent use are differentially heritable and hence separable to some extent. Although few studies using animal models have manipulated alcohol exposure age, those studies that have have typically observed timing-specific exposure effects, with more marked (or at least different patterns of) lasting consequences evident after exposures during early-mid adolescence than late-adolescence/emerging adulthood, and effects often restricted to male rats in those few instances where sex differences have been explored. As one example, adult male rats exposed to ethanol during early-mid adolescence (postnatal days [P] 25-45) were found to be socially anxious and to retain adolescent-typical ethanol-induced social facilitation into adulthood, effects that were not evident after exposure during late-adolescence/emerging adulthood (P45-65); exposure at the later interval, however, induced lasting tolerance to ethanol's social inhibitory effects that was not evident after exposure early in adolescence. Females, in contrast, were little influenced by ethanol exposure at either interval. Exposure timing effects have likewise been reported following social isolation as well as after repeated exposure to other drugs such as nicotine (and cannabinoids), with effects often, although not always, more pronounced in males where studied. Consistent with these timing
