To improve the well-being of adolescents with epilepsy, research is needed on how adolescents cope. In this study, Lazarus' model of stress and coping and Antonovsky's Theory of Sense of Coherence were used as the theoretical framework. The aim was to describe the lived experience of adolescents with epilepsy and their coping skills. The participants were 13-19 years old with an epilepsy diagnosis but without mental retardation or cerebral palsy. The study was performed in southern Sweden at the pediatric department of a university hospital. Semistructured and open-ended interviews were conducted with 13 adolescents. The transcripts were analyzed with manifest and latent content analysis. All the adolescents had developed strategies to cope with the emotional strains caused by epilepsy. They experienced strains from the seizures, limitation of leisure activities, side effects of medication, and feelings of being different. The coping strategies described were finding support, being in control, and experimenting.

Full Text Available Adolescence is described by the Swedish National Board of Health and Welfare as the healthiest period in life. However, adolescent girls differ in that they self-report that their health decreases with age. The aim of this hermeneutical study was to describe the meaning of living conditions in relation to adolescent girls’ health. Guided by principles of reflective lifeworld research, 15 interviews with adolescent girls were analysed. The result section consists of four narratives with their existential interpretations illustrating different ways of approaching living conditions and their meaning for health and well-being. The narratives are: Approaching everyday life in a balanced way—feeling harmonious; approaching everyday life with ambiguity—feeling confused; approaching everyday life as an intellectual project—striving for control; approaching everyday life as a struggle—feeling forlorn. In addition, a comprehensive understanding was developed by using the lifeworld dimensions: lived body, lived room, lived time, and lived relations. These dimensions may deepen the understanding of important parts of those living conditions which are meaningful for the girls’ health and well-being. By using the dimensions, complex living conditions have been explored and the meaning of different parts clarified. The girls’ thoughts and feelings are often ambiguous and sometimes contradictory, depending on the situation. The health of adolescent girls needs to be understood against the background of their experiences of living conditions. One way to support their health and well-being seems to be to supply them with forums where they can talk about their living conditions.

Children and adolescents in underserved populations have health care risks that are different from those of the adult population. Providers need to be aware of these needs and the available resources. Providers should work with school and community organizations to provide timely and appropriate preventive health care and screen for medical and mental health problems that occur more commonly in these high-risk patient populations.

BACKGROUND: Long-term, mental well-being of adolescence and young adults diagnosed with venous thromboembolism (VTE) as experienced by the patients has received little attention. OBJECTIVE: The purpose of this study was to explore the essential meaning of adolescents' and young adults' lived...... experiences following VTE to gain an in-depth understanding of their long-term, mental well-being. METHODS: Semistructured interviews were conducted with 12 Danish patients who were diagnosed with VTE in adolescence or young adulthood. Interviews were analyzed according to a phenomenological hermeneutical...... approach inspired by the French philosopher Paul Ricœur's theory of interpretation. RESULTS: Four themes emerged. Participants described an experience of a creeping loss of youth immortality, a perception of being different, to live with a body in a state of alarm, and feel symptom management insecurity...

Treatment for adolescents with sexually maladaptive behaviors is a continuing intervention that is changing and developing as greater understanding about this population of adolescents is obtained. The majority of treatment programs for adolescent sexually maladaptive behavior contain programming components that include cognitive distortions/thinking errors. Interviews including a conceptual mapping exercise were conducted with four adolescents adjudicated to a secure care program for sexual behaviors. All four boys completed an interview and a conceptual map of their perceived experiences as an adolescent with sexual maladaptive behaviors. All interviews were audio recorded. Analysis of the interviews and conceptual mappings yielded five themes present in the boys' experience as well as a consideration of the role early trauma may have in the establishment of cognitive distortion development. Contributing environmental and familial factors also play an important part in sustaining cognitive distortion. Main themes include: loss of responsible father or father figure, inability to regulate emotion, lack of personal and parental boundaries, and early exposure to pornography. The contributing influence of responsible male father figures may play an even greater role in the lives of young males than originally thought. How the adolescent inaccurately perceives his environment--in essence what he tells himself and continues to tell himself to make sense of his world--are building blocks in the development and continuation of thinking errors/cognitive distortions used to commit and justify sexual offending behaviors.

This study investigated whether intuitive, naive conceptions of "living things" based on objects' mobility (movement = alive) persist into adolescence and affect 10th graders' accuracy of responses and reaction times during object classification. Most of the 58 students classified the test objects correctly as living/nonliving, yet they demonstrated significantly longer reaction times for classifying plants compared to animals and for classifying dynamic objects compared to static inanimate objects. Findings indicated that, despite prior learning in biology, the intuitive conception of living things persists up to age 15-16 years, affecting related reasoning processes. Consideration of these findings may help educators in their decisions about the nature of examples they use in their classrooms.
Full Text Available Abstract Background In Bangladesh, particularly in urban slums, married adolescent women’s human rights to life, health, and reproductive and sexual health remain adversely affected because of the structural inequalities and political economic, social and cultural conditions which shape how rights are understood, negotiated and lived. Methods The focus of the research and methods was anthropological. An initial survey of 153 married adolescent women was carried out and from this group, 50 in-depth interviews were conducted with selected participants and, from the in-depth interviews, a further eight case studies of women and their families were selected for in-depth repeated interviews and case histories. Results This paper speaks of the unanticipated complexities when writing on reproductive rights for poor adolescent women living in the slums, where the discourses on ‘universal human rights’ are often removed from the reality of adolescent women’s everyday lives. Married adolescent women and their families remain extremely vulnerable in the unpredictable, crime-prone and insecure urban slum landscape because of their age, gender and poverty. Adolescent women’s understanding of their rights such as the decision to marry early, have children, terminate pregnancies and engage in risky sexual behaviour, are different from the widely accepted discourse on rights globally, which assumes a particular kind of individual thinking and discourse on rights and a certain autonomy women have over their bodies and their lives. This does not necessarily exist in urban slum populations. Conclusions The lived experiences and decisions made pertaining to sexual and reproductive health and ‘rights’ exercised by married adolescent women, their families and slum communities, allow us to reflect on the disconnect between the international legal human rights frameworks as applied to sexual and reproductive health rights, and how these are played out on

I analyze the effects of Catholic schooling, Protestant schooling, and homeschooling on adolescents' religious lives and test three mechanisms through which these schooling strategies might influence religiosity: friendship networks, network closure, and adult mentors. Data from Wave 1 of the National Survey of Youth and Religion suggest that Catholic schoolers attend religious services more frequently and value their faith more highly than public schoolers, but attend religious education classes and youth group less often. Protestant schoolers' involvement in their local congregation is similar to public schoolers', but their faith plays a more salient role in their life and they are more active in private religious activities. Homeschoolers do not differ significantly from public schoolers on any outcome considered. Moreover, friendship networks, network closure, and adult mentors play a very limited role in mediating the relationships between schooling strategies and adolescent religiosity. Interpretations of these findings are presented and discussed.

This population-based study examined whether residential or school neighborhood access to fast food restaurants is related to adolescents’ eating frequency of fast food. A classroom-based survey of racially/ethnically diverse adolescents (n=2,724) in 20 secondary schools in Minneapolis/St. Paul, Minnesota was used to assess eating frequency at five types of fast food restaurants. Black, Hispanic, and Native American adolescents lived near more fast food restaurants than white and Asian adolescents and also ate at fast food restaurants more often. After controlling for individual-level socio-demographics, adolescent males living near high numbers fast food restaurants ate more frequently from these venues compared to their peers. PMID:23064515
Full Text Available Group models are commonly used to treat eating disorders; however, research in this area remains largely underdeveloped. Interest in group work is likely to increase due to the demands on the public health system and the cost-effectiveness of group modalities. This scoping review sought to explore the evidence underpinning group therapy for adolescents living with an eating disorder. A literature search of 10 academic databases and four gray literature databases was undertaken in 2013. Selected Internet resources were searched and the author consulted professionals from Eating Disorders Victoria, the Butterfly Foundation, and the University of Melbourne. A total of 11 peer-reviewed articles published between 2003 and 2013 were included for review. There was an overall lack of research with no randomized-controlled trials available. Six program evaluations and five program descriptions were found, and they reported on a range of eating disorders and group modalities. The program evaluations suggested the utility of group therapy for promoting weight restoration in underweight individuals living with an eating disorder. Cognitive behavioral therapy groups were found to be more effective for bulimia nervosa and multifamily group therapy showed promise for anorexia nervosa. More rigorous research is needed to establish the effectiveness of group therapy for adolescents living with an eating disorder.

Full Text Available INTRODUCTION: Viral hepatitis is an important public health problem in Brazil and around the world.OBJECTIVE: To evaluate vaccination coverage against hepatitis B in adolescents and to identify the associated factors and reasons for non-adherence.METHODS: A cross-sectional population-based study with sampling by clusters and in two stages, carried out from records of 702 adolescents aged 11 to 19 years old, non-institutionalized, living in an urban area of Campinas, São Paulo, Brazil, in 2008/2009. The data were obtained from the Health Survey in the city of Campinas (ISACamp.RESULTS: The prevalence of vaccination (3 doses was 72.2%. An independent and negative association with the vaccine was observed for the adolescents who were not born in the municipality. The orientation of a health care provider was positively and significantly associated with vaccination. The main reasons for non-adherence were the lack of orientation and not considering the vaccine necessary. Socioeconomic factors, health behaviors and conditions did not restrict the access to vaccination, but the coverage was below the target established by the Ministry of Health in Brazil.CONCLUSION: Health education programs, addressing the importance of vaccination to prevent the disease; strategies to actively reach out adolescents that did not complete the schedule; as well as orientation from the health care professional about the benefits of the vaccine to the adolescents, parents and guardians can extend the vaccination coverage.

Purpose of this study was to study the oxidative stress status through the urinary 15-F(2t)-isoprostane (15-F(2t)-isoP) among a group of 168 adolescents, differently exposed to passive tobacco smoke. Subjects were enrolled, with written informed consent, between two populations of students living and attending school in two areas with different levels of urbanization in Piedmont Region, North-Western Italy. A general linear model (GLM) analysis was performed to evaluate the role of air pollution, dependent from selected degree of urbanization and of passive exposure to tobacco smoke, quantified through cotinine, in the synthesis of 15-F(2t)-isoP, measured with ELISA technique. Formaldehyde (FA) concentration in air was also evaluated as a primary confounding factor in oxidative stress but no significant differences between the two sites were found. Conversely, direct relationship between oxidative stress status and residence of adolescents was found: oxidative stress level was 31% higher for adolescents living in Chivasso (urban site) than for those living in Casalborgone (countryside area). Furthermore, also passive tobacco smoke exposure proved to play another important direct role in the distribution of 15-F(2t)-isoP levels (psmoke passively breathed could provide new and useful knowledge for the appraisal of preventive strategies, particularly for young subjects.

Most adolescents are placed in residential youth care (RYC) because of severe psychosocial strains and child maltreatment, which represent risk factors for developing mental disorders. To plan RYC units and ensure that residents receive evidence-based psychiatric interventions, it is necessary to obtain reliable and valid prevalence estimates of mental disorders in this population. However, there is a lacuna of research on diagnoses derived from standardized clinical interviews. The aim of this study was to assess the prevalence and comorbidity of mental disorders applying diagnostic interviews in an entire population of adolescents living in RYC in Norway. All young people in RYC were invited to participate in the study. Eighty-six RYC institutions with 601 eligible adolescents were included and 400 adolescents, 12-20 years old, participated in the study, yielding a response rate of 67 %. Anonymous Child Behaviour Checklist scores for 141 (70 %) of the declining residents were also available, allowing diagnoses according to the Diagnostic and Statistical Manual of Mental Disorders Fourth Edition (DSM-IV) for 541 youths to be estimated. Diagnoses were assessed by trained interviewers with the Child and Adolescent Psychiatric Assessment interview (CAPA). Seventy-six point two per cent (71.5-80.8 CI 95 %) of adolescents received at least one 3-month DSM-IV diagnosis. Prevalence rates for internalizing psychiatric disorders were higher than for behavioural disorders. Comorbidity was high between these two groups. Mental disorders were prevalent among children and youth in RYC. Our results create major concerns and challenge the existing organization of the RYC system.

Objective Metabolic syndrome (MetS), defined as the clustering of three of five risk factors (hypertension, obesity, triglyceridemia, dyslipidemia and hyperglycemia), is being increasingly mentioned among children and adolescents despite there being no consensus on how it should be defined in this set of population. Furthermore, very few studies have focused on MetS in children and adolescents in sub-Saharan populations. This study, therefore, aimed at determining the prevalence of the MetS and contributing risk in adolescents living in Mthatha, South Africa. Research design and methods Four hundred and ten adolescents (age range: 13–18 years, both sexes) were recruited into this cross-sectional study. In addition to a lifestyle questionnaire being administered, anthropometric measurements (weight, height and waist circumferences) were carried out for each participant. Fasting venous blood was collected for lipid profile and blood glucose assessments. Blood pressure was also measured. MetS was assessed using appropriate diagnostic criteria for children and adolescents. Results Complete data sets were collected from 371 participants. Females showed an elevation in the risk factors for MetS. Of the 371 participants, 40.2% were overweight/obese (47.5% females; 22.5% males). MetS was diagnosed in 3.1% female participants compared with 6.0% in male participants. Conclusions More risk factors for the MetS are seen among the overweight/obese as compared to lean adolescents. Given the fact that childhood overweight/obesity often continues into adulthood, it is important to address the causes of increased risk for MetS earlier in life to prevent the development of disease in adult life.

Pedometers may provide valuable information regarding the ambulatory patterns of adolescents, but the effects of body mass index (BMI) on pedometer accuracy in this population are unknown.The purpose of this study was twofold: 1) to determine whether the New Lifestyles NL-2000 (NL) and the Digi-Walker SW-200 (DW) (New Lifestyles, Inc., Lees Summit, MO) yield similar step counts as compared with an ankle-mounted criterion, StepWatch 3, when worn by early adolescents in a free-living environment and 2) to study whether BMI percentile affects the accuracy of waist-mounted pedometers in adolescents. Seventy-four early adolescents (13.0 ± 1.1 yr) wore the devices during one weekday. The study population included 33 normal weight, 21 overweight, and 20 obese participants. Two-way repeated-measures ANOVA was used to determine whether the BMI and the device were related to the number of steps per day and percentage of actual steps. The NL and DW recorded fewer steps than the StepWatch 3 in each BMI category (P < 0.05). In the obese group, the DW underestimated the steps more than the NL (P < 0.001). For the normal weight, overweight, and obese groups, the NL counted 89.1%, 89.1%, and 91.6% of the steps, respectively, whereas the DW counted 86.7%, 84.6%, and 72.7%, respectively. Researchers must be cognizant of the limitations of waist-mounted pedometers and carefully choose a device that suits the needs of their investigations. Because of the inaccuracies of the DW when measuring steps in obese adolescents, careful consideration must be given before choosing this device for research and interventions. The NL is a better device for assessment of adolescents' steps than the DW, especially for those who are obese.

Perceptions of present, ideal, and future lives among 12 Chinese adolescents experiencing economic disadvantage were examined via qualitative interviews. Results showed that most of the adolescents evaluated their present lives positively. In general, they also had positive perceptions of their future lives, although there also were some negative feelings. Although money did not play an important role in their perceptions of present lives, future lives, life goals, and ideal careers, economic sufficiency emerged as a major theme from the perspective of their ideal lives. While adolescents with better psychosocial adjustment appeared to evaluate their present lives more positively than did adolescents with relatively poorer psychosocial adjustment, no differences were found between the two groups in terms of their views on ideal and future lives.

To estimate the proportion of live-attenuated influenza vaccine (LAIV) doses administered beyond expiry date in children and adolescents during influenza seasons 2013-2014 and 2014-2015 in the UK. This was a retrospective cohort study. Two cohorts of children and adolescents who received LAIV from 1 September 2013 to 31 March 2014 and from 1 September 2014 to 31 March 2015 and aged 2-17 years at time of LAIV administration were identified from the Clinical Practice Research Datalink (CPRD). More than 500 primary care practices in the UK. Proportions of vaccine doses administered beyond expiry date were assessed among 47 396 and 67 099 LAIV recipients with a documented vaccine lot identifier in influenza seasons 2013-2014 and 2014-2015, respectively. None. Administrations of expired LAIV were ascertained by comparison of vaccination dates in CPRD records with expiration dates in AstraZeneca/MedImmune lot distribution data. Overall, 245 LAIV recipients, 80 in 2013-2014 and 165 in 2014-2015, received a dose after its expiration date, yielding proportion estimates of 1.7 per 1000 doses (95% CI 1.3 to 2.1) in season 2013-2014 and 2.5 per 1000 (95% CI 2.1 to 2.8) in season 2014-2015. This proportion increased above 1.0% after December during each season. Most (84% in influenza season 2013-2014 and 59% in influenza season 2014-2015) received an expired dose expiration date. The proportion was higher in London (relative risk 1.93 (95% CI 1.25 to 2.99)) and when the number of LAIV recipients registered in the practice was lower than the median number per practice (relative risk 2.69 (95% CI 1.99 to 3.62)). Administration of expired LAIV doses occurs infrequently. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017. All rights reserved.

Full Text Available Poverty is a pressing problem in the scale of the national economy, and within regions. In agricultural regions a large proportion of the population is engaged in agricultural production, where the pay is low. In such regions the scale of poverty are significant. Poverty also has negative social potential. Low standard of living remains one of the main obstacles to increasing the birth rate and to the solution to the population problem. One of the main indicators of quality of life is the size of per capita income. This indicator allows us to compare the standard of living of the populations in the same region and between subjects. To assess the level of material security in Russia we often use two indicators: a living wage and the minimum consumer budget. The concept of “poverty” and “living wage” used in the world as equivalent. The dimensions of these parameters are determined by the value of the minimum allowable limits of use below which normal human development is impossible. The author conducts an analysis of selected indicators of living standards of the population of the Krasnodar region. One of the areas of analysis appears characteristic of households with wealth lower than subsistence minimum. Poverty is directly related to the unequal distribution of income and property. The article analyzes the socio-economic differentiation of the population of the Kuban region

To investigate the psychological well-being among adolescents of HIV-positive parents. This study was involving 298 adolescents from 10 to 18 years old, including 54 adolescents of both parents living with AIDS or HIV, 114 adolescents of one parent living with AIDS or HIV and another 130 adolescents from normal families. Only one adolescent was studied per family. All participants completed an anonymous questionnaire. Psychological health, satisfaction on life, self-esteem and coping style were evaluated by SCL-90, Multidimensional Students' Life Satisfaction Scale, Self-esteem Scale and Simplified Coping Style Questionnaire. The total score and 10 factors of the SCL-90 in the adolescents of parents living with HIV or AIDS was higher than the adolescents from normal families and those scores in the adolescents of both parents living with HIV or AIDS were the highest. There were 27.8% of the adolescents with both HIV-positive parents were having the total score of SCL-90 more than 160 or at lest one of the 10 factors' score more than 3. The detected rate of adolescents with one HIV-positive parent was 16.7%, higher than those adolescents from normal families (8.5%) and with significant difference (chi2 = 11.457, P = 0.003). 50.0% of the adolescents with both HIV-positive parents, were having one or more factor' score between 2.0 and 3.0, compared to the rate (37.0%) of adolescents with one HIV-positive parent. The rate was higher than the adolescents from normal families (29.8%) and with significant difference (chi2 = 7.250, P = 0.027). Among the students from normal families, the total score and the 5 dimensionalities' score of the MSLSS were lower than those adolescents of parents living with AIDS or HIV. In the friend dimensionality, the score of the adolescents from normal families was significantly higher than the adolescents of parents living with AIDS or HIV. The scores of self-esteem, positive coping style and negative coping style were not significantly
Full Text Available Aim: The study was planned and implemented with the purpose of determining the relationship between the nutritional and physical activity conditions of adolescents living in orphanages in Ankara and their body compositions. Material and Methods: Research implemented by taking permission from Ethic Council of Gazi University Faculty of Medicine. 198 adolescents (115 boys, 83 girls within the age group 13-18 living in orphanages, constitute the population of the study. Data’s were collected in three stages; in the first stage, the question set developed to determine the nutritional status and habits. In the second stage, food consumption and physical activities of adolescents were recorded. In the third stage, anthropometric measurements were taken. Results: It was found that 69.6% boys and 91.6% of girls skipped meals, and among those skipping meals, 34.8% of boys and 61.4% of girls skipped breakfast most. More than half of boys (63.0% and girls (65.0% were pickers as regards what they eat, 17.2% of adolescents never consumed milk, and 40.9% never consumed red meat. When daily mean energy and nutrient intakes of adolescents were evaluated according to Nutrition Guide Unique for Turkey, boys ate diets insufficient in vitamin A, folic acid, Vitamin B12, potassium, calcium and magnesium, girls ate diets insufficient in energy, vitamin A, Vitamin B1, folic acid, Vitamin B12, potassium, calcium, magnesium and phosphorus. Anthropometric measurements of adolescents were within normal limits; however, their activity levels were below those recommended. Conclusion: HEI score for 15.7% of adolescent boys (n=18 were evaluated as “bad” for 80.9% (n=86 as “medium” and for 3.5% (n=6 as “good”. It is recommended that implementing a training program for correcting the diet habits and the knowledge in nutrition of adolescents living in orphanages.
As with school age children, it is difficult to make conclusions about the validity of available dietary assessment instruments for adolescents because of the differences in instruments, research designs, reference methods, and populations in the validation literature.

Full Text Available The aim of this study is determining the prevalence of smoking stages in adolescents of Tabriz city (northwest of Iran and identifying the personal, environmental, and psychological factors relating to cigarette smoking. Fifty-seven high schools were randomly selected, and 4903 students were completed a self-administered questionnaire about cigarette smoking and the related risk factors. The association of independent variables with cigarette smoking was evaluated using the ordinal logistic regression model. In total, 17.3% of the participants were experimenters (95% CI: 15.8-18.9 and 5.0% were regular smokers (95% CI: 3.7-6.2. The results showed that the male gender (OR=2.92; CI: 1.94-4.77, age (OR=1.27; CI: 1.02-1.64, having general risk taking behavior (OR=1.50; CI: 1.02-2.21, presence of a cigarette smoker in the family (OR=1.78; CI: 1.23-2.54, friendship with close cigarette smoker friends (OR=2.52; CI: 1.65-3.86, substance abuse experience (OR=8.27; CI: 2.61-25.61, attitude toward cigarette smoking (OR=1.22; CI: 1.10-1.27 and positive thinking about cigarette smoking (OR=1.05; CI: 1.01-1.14 are associated to cigarette smoking in adolescents. The cigarette smoking prevalence is minimal in Tabriz city adolescents, especially in girls; but the experimenter prevalence is considerable. Findings of this study justifies adopting more serious measures in the pre-adolescence and adolescence period.

Full Text Available In the Milazzo-Valle del Mela area, the presence of industrial plants and the oil refinery make local residents concerned for their health. For this reason, we evaluated the levels of heavy metals in 226 children aged 12–14 years, living in the 7 municipalities of the area. A control age-matched population (n=29 living 45 km far from the industrial site was also enrolled. Arsenic, cadmium, chromium, mercury, nickel, and vanadium were analysed in 24 h urine samples, while lead concentration was evaluated in blood samples. A questionnaire regarding life style and risk perception was also administered. Adolescents from Milazzo-Valle del Mela had cadmium levels significantly higher compared to either controls (P<0.0001 or the reference values of the European Germany Environmental Survey (GerES-IV and the American National Health and Nutrition Examination Survey (NHANES. Furthermore, children had higher perception of living in a high-risk environment. The present data, for the first time, clearly indicate that adolescents living in Milazzo-Valle del Mela have increased body concentration of cadmium, which may be harmful to human health. These results deserve particular attention by the local and regional government to initiate prevention programmes in this susceptible population.
Full Text Available Background: Resilience is one of the main factors affecting human health, and perceiving its meaning for high-risk adolescents is of particular importance in initiating preventive measures and providing resilience care. Objectives: This qualitative study was conducted to explain the meaning of resilience in the lived experiences of Iranian adolescents living in governmental residential care facilities. Materials and methods: This study was conducted using the hermeneutic phenomenological method. Semi-structured interviews were conducted with eight adolescents aged 13–17 living in governmental residential care facilities of Tehran province affiliated to the Welfare Organization of Iran who articulated their experiences of resilience. Sampling lasted from May 2014 to July 2015 and continued until new themes were no longer emerging. The researchers analyzed the verbatim transcripts using Van Manen's six-step method of phenomenology. Results: The themes obtained in this study included “going through life's hardships,” “aspiring for achievement,” “self-protection,” “self-reliance,” and “spirituality.” Conclusion: Our study indicates that the meaning of resilience coexists with self-reliance in adolescents’ lived experiences. Adolescents look forward to a better future. They always trust God in the face of difficulties and experience resilience by keeping themselves physically and mentally away from difficulties. Adverse and bitter experiences of the past positively affected their positive view on life and its difficulties and also their resilience. The five themes that emerged from the findings describe the results in detail. The findings of this study enable nurses, health administrators, and healthcare providers working with adolescents to help this vulnerable group cope better with their stressful life conditions and improve their health through increasing their capacity for resilience.

Conclusions: Mental health issues should be addressed proactively during adolescence for all HIV-infected youth. In addition, care systems need to pay greater attention to how mental health support is integrated into the care management for HIV, particularly throughout lifespan changes from childhood to adolescence to adulthood. The lack of research and support for mental health needs in resource-limited settings presents an enormous burden for which cost-effective solutions are urgently needed.

Full Text Available Introduction: Avoiding unintended pregnancies is important for the health of adolescents living with HIV and has the additional benefit of preventing potential vertical HIV transmission. Health facility providers represent an untapped resource in understanding the barriers and facilitators adolescents living with HIV face when accessing contraception. By understanding these barriers and facilitators to contraceptive use among adolescent females living with HIV, this study aimed to understand how best to promote contraception within this marginalized population. Methods: We conducted structured in-depth interviews with 40 providers at 21 Family AIDS Care & Education Services - supported clinics in Homabay, Kisumu and Migori counties in western Kenya from July to August 2014. Our interview guide explored the providers’ perspectives on contraceptive service provision to adolescent females living with HIV with the following specific domains: contraception screening and counselling, service provision, commodity security and clinic structure. Transcripts from the interviews were analyzed using inductive content analysis. Results: According to providers, interpersonal factors dominated the barriers adolescent females living with HIV face in accessing contraception. Providers felt that adolescent females fear disclosing their sexual activity to parents, peers and providers, because of repercussions of perceived promiscuity. Furthermore, providers mentioned that adolescents find seeking contraceptive services without a male partner challenging, because some providers and community members view adolescents unaccompanied by their partners as not being serious about their relationships or having multiple concurrent relationships. On the other hand, providers noted that institutional factors best facilitated contraception for these adolescents.

A rights-based approach in HIV service delivery for adults is increasingly taking root in sub-Saharan Africa in the context of greater availability of antiretroviral therapy. Yet there has been comparatively little progress in strengthening a rights-based approach to adolescent HIV services, which we learned during a qualitative study in 2010 among 111 adolescents living with HIV, 21 parents and 38 health providers in three districts in Zambia. Adolescents in the study expressed a range of information and support needs and wanted locally relevant interventions to meet those needs. They wanted greater access to HIV, sexual and reproductive health information, information on how to protect themselves, privacy and confidentiality in service sites, skills training so as to be able to earn money, and better control over disclosure of their HIV status to others. Both health workers and parents acknowledged that information and services needed to be improved to meet those needs far better. This paper provides examples of successful programmes in Zimbabwe, Uganda, Tanzania, Botswana and South Africa and calls for adolescent services to be linked to both paediatric and adult services, peer networks to be established to increase adolescents' ability to collectively voice their concerns and support each other, interventions supporting adolescents' control over self-disclosure, and lastly that adolescent health should become a training specialty in sub-Saharan Africa.

Cancer affects not only the patient but also their entire family, especially adolescents. Adolescents whose parents are ill may manifest their distress through changes in school performance, physical complaints of pain and discomfort, as well as changes in social and interpersonal relations. There has been very little research about the effects of cancer on adolescents in Iran. The purpose of this qualitative study was to explore the Iranian adolescents' experiences when living with a parent with cancer. In this research, the descriptive-explorative approach was used. There were a total of 27 participants. Purposeful sampling was used and data collection methods were semi-structured deep interviews. Constant comparative analysis was used to study the data. The findings of this study showed that the main experiences of these adolescents were categorized into seven themes: 1- psychological problems of adolescents; 2- supportive-educative needs; 3- cancer as a two edged sword in family relationships; 4- stages of confrontation with the parent's cancer; 5- effect of cancer on social dimensions; 6- affective and helpful supportive agents; 7- Need of support for education under special conditions. This research showed that Iranian adolescents had the same experiences as other adolescents in other countries in many aspects yet in some issues, such as religious strategy, they had strong religious beliefs that would help them cope with their parents' cancer. Also it was shown that we must plan a program in which education and support should be provided to enable adolescents to cope with this detrimental situation with minimal disruption.

To gain an understanding of everyday anxiety among late adolescents during high school. An interpretive phenomenological approach was utilized. A purposive sample of eight males and females in late adolescence with everyday anxiety were interviewed. Individual interviews were conducted. Data analysis was undertaken throughout the research study by utilizing a thematic analysis of text in which themes emerged to understand the lived experience of everyday anxiety among late adolescents during high school. The study revealed themes reflective of the lived body in time and space and in relation with others. The three themes were (a) the embodied experience of anxiety with the subtheme of the body and mind responds; (b) feeling uncomfortable in the lived space of school with the subthemes of the lived relations of bullying, the internal/external space of isolation, and the constant pressure to perform well; and (c) life at home with the subthemes of the lived space of home, the lived relations of pressure from parents, and life will get better. Nurses need to provide holistic care for late adolescents experiencing everyday anxiety by focusing on healing the whole person through the unity of body, mind, emotion, spirit, and environment.

Full Text Available The aim of this study was to examine the hypothesis that Taiwanese aboriginal adolescents feature more severe psychopathology than non-aboriginal adolescents who live in the same mountainous region of southern Taiwan, and to test the hypothesis by controlling other individual and environmental factors. In this study, a total of 251 aboriginal and 79 non-aboriginal Taiwanese adolescents were enrolled. Their psychopathology was measured by the Symptom Checklist-90-Revised Scale; demographic and family characteristics, and their affinity with their peer group and with their school were also assessed. The results of the multiple regression analysis revealed that aboriginal adolescents feature more severe psychopathology than non-aboriginal adolescents, and indicated that females and adolescents perceiving higher levels of family conflict and lower family support were more likely to experience more severe psychopathology than those perceiving the contrary. Those who devise strategies to improve the mental health of adolescents living in impoverished regions must take into consideration their ethnicity, gender, and family context when devising such treatment strategies.

Many rare diseases of childhood are life-threatening and chronically debilitating, so living with a rare disease is an on-going challenge for patients and their families. MPS is one of a range of rare inherited metabolic disorders (IMDs) that come under category 3 of life-limiting conditions, where there is no curative treatment available at present. Although the study of rare diseases is increasingly novel, and of clinical importance to the population, the lack of empirical data in the field to support policy and strategy development is a compelling argument for further research to be sought. This qualitative hermeneutic phenomenological study explored and interpreted Irish parents' experiences of living with and caring for children, adolescents and young adults with MPS and the impact of these diseases on their day to day life. A purposively selected sample of parents' attending the Irish National Centre for Inherited Metabolic Disorders was invited to participate in serial in-depth interviews. A total of eight parents' (n = 8) of children with a range of MPS disorders aged from 6 months to 22 years (MPS I Hurler syndrome, Scheie syndrome), MPS II (Hunter syndrome), MPS III (Sanfilipo syndrome) and MPS VI (Maroteaux-Lamy syndrome) were interviewed at three time points over a 17 month period. The main themes identified during data analysis were described as living with MPS, living with a genetic rare disease, the stigma of a rare condition, MPS as encompassing multiple diseases, Unknown future, hospital vs. home, experience of waiting, a tough road ahead, and things in their day-to-day life with MPS. They spoke of their child's Quality of Life (QoL), their healthy children's wellbeing, and for some, the impact on their own physical and psychological wellbeing. They also reflected on issues of stigmatisation and isolation in their experience of living with a child with a rare disorder. This study's findings reflect the wider literature on the impact of rare

Adolescents living in low- and middle-income countries (LMICs) are disproportionately burdened by the global HIV/AIDS pandemic. Maintaining medication adherence is vital to ensuring that adolescents living with HIV/AIDS receive the benefits of antiretroviral therapy (ART), although this group faces unique challenges to adherence. Knowledge of the factors influencing adherence among people during this unique developmental period is needed to develop more targeted and effective adherence-promoting strategies. This systematic review summarizes the literature on quantitative observational studies examining correlates, including risk and resilience-promoting factors, of ART adherence among adolescents living with HIV/AIDS in LMICs. A systematic search of major electronic databases, conference-specific databases, gray literature, and reference lists of relevant reviews and documents was conducted in May 2014. Included studies examined relationships between at least one factor and ART adherence as an outcome and were conducted in primarily an adolescent population (age 10-19) in LMICs. The search identified 7948 unique citations from which 15 studies fit the inclusion criteria. These 15 studies identified 35 factors significantly associated with ART adherence representing a total of 4363 participants across nine different LMICs. Relevant studies revealed few consistent relationships between measured factors and adherence while highlighting potentially important themes for ART adherence including the impact of (1) adolescent factors such as gender and knowledge of serostatus, (2) family structure, (3) the burdensome ART regimens, route of administration, and attitudes about medication, and (4) health care and environmental factors, such as rural versus urban location and missed clinic appointments. Rates of adherence across studies ranged from 16% to 99%. This review identifies unique factors significantly related to ART adherence among adolescents living in LMICs. More

Socioeconomic status has been associated with obesity in children and adolescents. This association may be dependent according with where adolescents lives. The aim of this study was to evaluate the association between different socioeconomic indicators such as parental education and occupation and socioeconomic status with abdominal obesity in adolescents from two observational studies: the Healthy Lifestyle in Europe by Nutrition in Adolescence cross-sectional study (HELENA-CSS) and the Brazilian Cardiovascular Adolescent Health (BRACAH) study. European (n = 3192, aged 12.5-17.5 years, with 53.1% girls from HELENA-CSS) and Brazilian (n = 991, aged 14-18 years, with 54.5% girls from BRACAH study) adolescents from two cross-sectional studies were included in this analysis. Complete data on waist circumference (WC), height, socioeconomic status indicators and several confounders were collected. Socioeconomic indicators were measured using a self-reported questionnaire in order to assess the family social status of the adolescents. Multilevel linear regression models were used to examine associations, and results were adjusted for potential confounders. Adjusted results showed inverse associations between mother's and father's education levels (p adolescents, both indicators of abdominal obesity did not remain associated with the independents variables, after adjustment for potential confounders. Abdominal obesity was associated with socioeconomic indicators in higher-income countries, but this association was not observed in a lower-middle-income country. © 2016 World Obesity Federation.

According to national survey data, dairy food consumption has fallen in recent years and declines further with age, especially from childhood to adolescence. Dietary surveys typically rely on retrospective dietary assessment methods and use broad age groupings (4-10 yr; 11-18 yr), making it challenging to differentiate between middle-childhood and adolescence. Consequently, there is a need to assess dairy food consumption during middle-childhood and adolescence using more robust dietary assessment tools. Therefore, the present study aimed to describe and compare patterns of dairy consumption throughout middle-childhood and adolescence. Dairy food consumption was assessed during school term-time over 4 consecutive days, including 2 weekdays and 2 weekend days, in a sample of free-living children (9-11 yr, n=40) and adolescents (15-18 yr, n=35). For children, free-living dairy intake was evaluated through parental-weighed food records, and for adolescents, a combined weighed self-reported food record and 24-h dietary recall technique was utilized. Food records were explored to determine types, amounts, and frequency of dairy food consumption, and were analyzed for differences between middle-childhood and adolescence using a between group 2×2 (age×sex) ANOVA. Descriptive data suggested that milk was the most popular dairy product consumed by both children and adolescents. Statistical analysis revealed a main effect for sex on total milk consumption (mL) and number of daily milk portions consumed. No interaction or main effect was present for any other variable. The present study indicates that independent of age, boys consumed greater amounts of milk compared with girls. Contrary to existing literature, findings suggest no difference in milk-based dairy consumption between middle-childhood and adolescence.

Optical gain from colloidal quantum dots has been desired for several decades since their discovery. While gain from multiexcitations is by now well-established, nonradiative Auger recombination limits the lifetime of such population inversion in quantum dots. CdSe cores isovalently doped by one to few Te atoms capped with rod-shaped CdS are examined as a candidate system for enhanced stimulated emission properties. Emission depletion spectroscopy shows a behavior characteristic of 3-level gain systems in these quantum dots. This implies complete removal of the 2-fold degeneracy of the lowest energy electronic excitation due to the large repulsive exciton-exciton interaction in the doubly excited state. Using emission depletion measurements of the trap-associated emission from poorly passivated CdS quantum dots, we show that 3-level characteristics are typical of emission resulting from a band edge to trap state transition, but reveal subtle differences between the two systems. These results allow for unprecedented observation of long-lived population inversion from singly excited quantum dots.
Adolescents found within single-parent families without a residential father have reported higher levels of sexual debut and higher levels of reported pregnancy. Using data from the Mobile Youth Survey, the purpose of this study is to determine the impact of the presence of a father figure on the sexual debut of African-American adolescents living in poverty and to determine if gender moderates the relationship between the presence of a father figure and sexual debut. Additionally, this study will examine the family processes in which the presence of a father figure can affect the sexual debut of African-American adolescents who live within economically and socially disadvantaged communities. The results revealed that African-American adolescents reporting a father figure had lower rates of sexual debut than those youth reporting no father figure. Gender was not found to be a significant moderator in the relationship between father figure presence and sexual debut. However, existing curfews and family rules did account for some of the effects of presence of a father figure and sexual debut. The results suggest that when adolescents have a father figure in their lives, it may reduce the possibility of early sexual debut.

A cross-sectional survey was conducted on 1135 students (13–16 years attending 13 secondary schools of Sicily, southern Italy. Validated instruments were used for dietary assessment and the KIDMED score to assess adolescents’ adherence to the MD. A higher adherence to the MD was associated with high socioeconomic status (Odds Ratio [OR] 1.53, 95% Confidence Interval [CI]: 1.03–2.26 and high physical activity (OR 1.19, 95% CI: 1.02–1.70, whereas lower adherence was associated with living in an urban environment (OR 0.65, 95% CI: 0.44–0.97 and being obese (OR 0.59, 95% CI: 0.37–0.94. The adolescents’ KIDMED scores were inversely associated with adolescents’ intake of sweets, fast foods, fried foods, and sugary drinks, and directly with fruit, vegetables, pasta, fish, and cheese intakes. Urban-living adolescents were less likely to eat fruit and more prone to consume meat, sugary drinks, and fast food than rural-living adolescents. The latter were more likely to eat sweets and snacks. A general poor quality of food consumption in Italian adolescents away from the MD was reported, especially among those living in urban areas.

Examined role of cigarette smoking in lives of low-income, pregnant adolescents (n=20). Findings indicated that subjects smoked to cope with increased weight gain; to deliver smaller infants which in turn would decrease duration of labor and reduce pain of delivery; and to establish identity separate from their parents' and peers' drug abuse.…
Full Text Available Aims: From the developmental perspectives children acquire and widen their perceptions of health as they mature and grow up. The main purpose of this study was to describe health through the eyes of adolescents in immigrant Ethiopian families living in Finland.Methods: Ten boys and five girls participated. The adolescents’ ages ranged from 12 to17. Theme interviews were used in data collection. Snowball sampling technique was used. Consent was obtained from the adolescents and adolescents’ parents. Inductive content analysis technique was used to analyse the data.Results: Adolescents indicated that health is the wellbeing of all dimensions that make us intact and complete. Adolescents believed relaxation, physical activity, good hygiene, good social relationship, avoiding consumption of poison substances, green nature, hygienic environment and peace are health supportive elements. On the contrary adolescents said insufficient resting, violent behaviors, difficulty, irritation, being inactive physically, addiction to alcohol and smoking, eating fatty food, not respecting meal time and use of drugs are health damaging behaviors. Adolescents consumed soft drink and alcohol frequently ,were physical inactive, practiced unhealthy eating habits, felt lazy to go and grab food from food store, faced financial difficulty to pay for Gym and healthy food that threatened their health. Adolescents used sport, socialization, moderate alcohol intake, avoid eating unhealthy food and smoking as their strategies to enhance their health.Conclusions: Adolescents were able to identify unhealthy lifestyles and healthy lifestyles. However adolescents were engaged in healthy and unhealthy lifestyles simultaneously. Thus family, school, neighbours and health care workers should work together and vigilant in assessing and removing factors that prevent adolescents from adopting healthy lifestyles.
As the age at marriage continues to rise in East and Southeast Asia, the fertility behavior of unmarried teenagers is receiving more attention from population policymakers. In addition to fertility reduction through family planning, Asian societies today consider population planning strategies in relation to national needs and social goals, including such matters as the population's growth rate, age structure, educational quality and skills. The number of single youth in Asia is growing much more rapidly than the total youth population. By the year 2010, for example, India is projected to have nearly 70 million single teenagers, aged 15-19, 188% more than in 1980. In many developing countries today, such as the Philippines and Korea, the rising age at marriage has combined with rapid urbanization, improved status for women, and more educational opportunity to alter both the behavioral norms of young people and the traditional means of social control over youth. Studies of contemporary adolescent sexuality have been conducted in 4 Asian countries. In the Philippines an overt independent youth homosexual culture was found to exist in urban and to some extent rural areas. In Thailand research revealed little conservative resistance to family planning or to contraceptives for young unmarried people. Surveys in Taiwan indicate that behavior related to dating and choice of spouse has become more liberal, and a survey in Hong Kong revealed a higher level of premarital sex and use of prostitutes among Chinese men than expected. Population policy perspectives that need to be considered in these changing times include: 1) issues of access to family planning services by unmarried people below the legal age of maturity; 2) the development of social institutions, such as exist in Thailand and the Philippines, to guide adolescents' behavior; 3) more extensive study of adolescent sexuality; 4) establishment of the scope of family policy.

Objective: The Substance Use Risk Profile Scale (SURPS) has been developed to screen personality risk factors for substance misuse. This scale assesses 4 high-risk personality traits using a 23-item, self-report questionnaire. SURPS helps guiding targeted approaches to prevention of substance abuse and misuse. It has been validated in the United Kingdom, English Canada, Sri Lanka, and China. This study aims to validate this scale in a sample of French-speaking adolescents from Quebec as well as its sensitivity in a clinical sample of adolescents. Method: Two hundred two 15-year-old youths from a community sample completed a French version of SURPS as well as other measures of personality and substance use. This study reports the internal consistency and concurrent validity of the scale, as well as a factor analysis of items. Further, 40 youths (mean age 15.7 years) from a clinical population completed SURPS and their scores were compared with those of the community sample. Results: SURPS French translation has good internal consistency and demonstrated a 4-factor structure very similar to the original scale. The 4 subscales show good concurrent validity, and 3 of the subscales were found to correlate with measures of substance use. Finally, 95% of the clinical sample was identified at high risk for substance misuse according to SURPS cut-off scores. Conclusion: SURPS French translation seems to be a valid and sensitive scale that can be used in a French-speaking adolescent population from Quebec.

This report analyzes the life span of Ig-containing cells (IgCC) in different sites of antibody production. The experimental approach was based upon the observations that most IgCC are derived from proliferating precursors while IgCC themselves are mainly nondividing end cells. Rats were given a continuous infusion of [3H] thymidine via an osmotic pump inserted in the peritoneal cavity. At intervals of 1, 3, 5 or 10 days after starting infusions, tissues were taken and analyzed by a combination of immunohistology and autoradiography to identify the proportions of IgCC which had gone through S phase of the cell cycle during the period of infusion. After 3 days infusion the median and (range) percent-labeled IgCC in the medullary cords of mesenteric and cervical lymph nodes and the red pulp of the spleen were, respectively, 88 (81-90), 75 (66-77) and 88 (82-93). Conversely that for IgCC in bone marrow was only 13 (11-17) and that in the lamina propria of the jejunum 47 (33-68). The rate of increase in labeling of bone marrow IgCC with length of infusion was approximately linear. Extrapolation of this slope suggests that bone marrow IgCC have a life span in excess of 3 weeks. The slopes of increase in IgCC labeled with time for lymph nodes and spleen were clearly biphasic suggesting that while most IgCC in these tissues have a life span of less than 3 days, there is also a minor population of long-lived IgCC. The lamina propria appears to have approximately equal proportions of long and short-lived IgCC. The life span of IgCC, with the exception of IgMCC, appears to be a feature of the site of antibody production rather than the Ig class produced. Almost all IgM-containing cells were found to be short lived.

Perceptions of living with inflammatory bowel disease (IBD) during adolescence were explored in a cross-sectional study with a multimethod design. The adolescents as a group described general well-being and ability to handle the disease, which was related to their self-reported self-esteem. However, a subgroup of adolescents with a severe disease course reported a more negative view of the impact of IBD in their daily lives. Encouraging adolescents to communicate in different ways may help professionals to identify vulnerable subgroups with impaired health and to provide more appropriate support and treatment for those most in need.

I analyze the effects of Catholic schooling, Protestant schooling, and homeschooling on adolescents’ religious lives and test three mechanisms through which these schooling strategies might influence religiosity: friendship networks, network closure, and adult mentors. Data from Wave 1 of the National Survey of Youth and Religion suggest that Catholic schoolers attend religious services more frequently and value their faith more highly than public schoolers, but attend religious education cla...
This article summarizes the activities at the ESCAP Population Division Expert Group Meeting on Adolescents that was held during September-October 1997 in Bangkok, Thailand. The meeting was a follow-up to the 1994 International Conference on Population and Development (ICPD). The meeting considered 1) the ICPD recommendations; 2) the recommendations contained in the Jakarta Plan of Action on Human Resource Development; and 3) the Proposals for Action on Human Resources Development for Youth in Asia and the Pacific. Participants included about 25 people from Australia, Bangladesh, China, India, Indonesia, Philippines, Sri Lanka, and Thailand. The conference relied on 8 invited experts, two resource persons, advisors from the UNFPA Country Support Team for East and Southeast Asia, and representatives of UNFPA, the Population Council, and the East-West Center. A concern was the declining age of menarche of girls in the ESCAP region and the increasing age of marriage. During the time of menarche and marriage, girls are migrating and moving away from their family and community in rural areas. Family structure and relationships are changing. Increases are observed in adolescent premarital sexual activity, the incidence of sexually transmitted diseases, substance abuse, teenage pregnancy, and abortion. The mass media and information technologies have both a positive and a negative influence on adolescents. Parent-child communication exchanges and teacher-student exchanges are "less than ideal." Old traditions and practices change slower than people change. Boys and girls are affected differently by the sociocultural and economic environment. The societal norms set expectations for behavior that may conflict with individual beliefs and practices. Changes brought by globalization and rapid economic growth provide greater opportunity for young girls and women to obtain employment and autonomy.

To analyze calcium intake in adolescents according to sociodemographic variables, health-related behaviors, morbidities, and body mass index. This was a cross-sectional population-based study, with a two-stage cluster sampling that used data from a survey conducted in Campinas, São Paulo, Brazil, between 2008 and 2009. Food intake was assessed using a 24-hour dietary recall. The study included 913 adolescents aged 10-19 years. Average nutrient intake was significantly lower in the segment with lower education of the head of the family and lower per capita family income, in individuals from other cities or states, those who consumed fruit less than four times a week, those who did not drink milk daily, those who were smokers, and those who reported the occurrence of headaches and dizziness. Higher mean calcium intake was found in individuals that slept less than seven hours a day. The prevalence of calcium intake below the recommendation was 88.6% (95% CI: 85.4-91.2). The results alert to an insufficient calcium intake and suggest that certain subgroups of adolescents need specific strategies to increase the intake of this nutrient.

Full Text Available Background: For establishing effective intervention, it is important to identify major determinants in an early stage of life. Effective prevention of adult obesity will require prevention and management of childhood obesity. Aims & Objectives: To study the epidemiological determinants of obesity in adolescent girls. Material & Methods: All adolescent school going boys and girls in the age group between 10 to 19 years were included as per definition of adolescent. 585 students were selected by systematic sample i.e. every 3rd student was included in the study sample. A pretested standardized questionnaire which consisted of questions related to sociodemographic data was used to screen the population for obesity. Results: When body mass index was correlated with various socioeconomic variables, it was found that prevalence of obesity was more in males (overweight- 20.84%;obese-5.43% as compared to females (overweight- 16.92%; obese-3.14%,more in the upper socioeconomic status (27.27% as compared to lower socioeconomic status(15%,more in subjects with more frequency of junk food(30.97% as compared to having occasional junk food (20.93,more in subjects with more frequency of eating sweets ( 25.73% as compared to occasional sweet eaters(13.59%. Conclusion: The dietary habits like more frequency of junk food, more sweet consumption, and socioeconomic status had a major impact on body mass index of children.

Objective: To record prevalence of malocclusion among 2,400 adolescents in Karnataka state, India and to define difference in malocclusion status in urban and rural population. Design: Randomized cross-sectional study. Setting: School students of Karnataka state, 24 August 2011 to 30 March 2012. Participants: School students in the age group of 13-17 years. Materials and Methods: Each individual was assessed for occlusal traits - sagittal occlusion, overjet, overbite, crowding, midline diastema, and crossbite. Statistical Analysis Used: Examinations were computerized and analyzed using Statistical Package for Social Sciences version 16. Chi-square test was used for computing statistical significance. Results: 87.79% of population had malocclusion. Out of which 89.45% had class I, 8.37% had class II, and 2.14% had class III malocclusion. Normal overjet and overbite was seen in 48.22 and 49.87% of subjects, respectively. Frequency of crowding was 58.12% and 15.43% of subjects had midline diastema. Anterior crossbite was present in 8.48% and posterior crossbite in 0.99%. Urban population had twice the class II sagittal occlusion, and increased overjet as compared to rural population. Conclusions: Malocclusion is widely spread among population of Karnataka state, with greater prevalence in urban population. Early exfoliation of deciduous teeth and refined diet can be considered as viable etiological factors. PMID:24778988

This research project examined the adolescent/young adult-parent relationships of African Jamaican immigrants currently living in Canada. Specifically, we focused on the transmission of cultural values and beliefs within these relationships and how the adolescents navigated and negotiated potential changes in these values because of their acculturative experiences. An examination of various mundane family/cultural practices provided insight into perceived transmission attempts by parents and the adolescent/young adult interpretation of these attempts. Twenty in-depth interviews were conducted with adolescent/young adult members of African Jamaican immigrant families living in Canada. Using Grounded Theory methodology (Glaser & Strauss, 1967), several themes emerged during the analysis of the interviews--the most significant being the issue of matrifocality within the African Jamaican family. Issues of respect and adolescent agency are also discussed as they related to the manner in which the adolescent/young adult attempted to negotiate various roles within the family.
Adolescent depression, has been identified as one of the important risk factors for adolescent safety. The American Academy of Pediatrics (AAP) recommends screening the adolescent population for depression with a validated screening tool at least once a year. Given the time constraints in primary care, many physicians tend to rely more on clinical questioning to screen depression.This has the potential to miss many adolescents who may have mild to moderate depression which may prove detriment...

A qualitative study was conducted with semi-structured interviews with the aim of understanding the experience of children and adolescents under palliative care when managing pain daily and how they describe the intensity, quality and location of pain. We used Piaget's theory of cognitive development as a theoretical framework and oral history as a methodological framework. We found four themes: describing pain; seeking a life closer to normality, despite pain and disease; using a variety of alternatives for pain control; and living with damaged physical appearance. Although pain is a limiting factor in the lives of children and adolescents, we found that they faced their daily pain and still had a life beyond pain and illness. In addition, we highlight the relevance of nurses' understanding that effective management of pain in children is essential for a normal life and less suffering.

Concussion injuries have been highlighted to the American public through media and research. While recent studies have shown increased traumatic brain injuries (TBIs) diagnosed in emergency departments across the United States, no studies have evaluated trends in concussion diagnoses across the general US population in various age groups. To evaluate the current incidence and trends in concussions diagnosed across varying age groups and health care settings in a large cross-sectional population. Descriptive epidemiological study. Administrative health records of 8,828,248 members of a large private-payer insurance group in the United States were queried. Patients diagnosed with concussion from years 2007 through 2014 were stratified by year of diagnosis, age group, sex, classification of concussion, and health care setting of diagnosis (eg, emergency department vs physician's office). Chi-square testing was used for statistical analysis. From a cohort of 8,828,248 patients, 43,884 patients were diagnosed with a concussion. Of these patients, 55% were male and over 32% were in the adolescent age group (10-19 years old). The highest incidence of concussion was seen in patients aged 15 to 19 years (16.5/1000 patients), followed by those aged 10 to 14 years (10.5/1000 patients), 20 to 24 years (5.2/1000 patients), and 5 to 9 years (3.5/1000 patients). Overall, there was a 60% increase in concussion incidence from 2007 to 2014. The largest increases were in the 10- to 14-year (143%) and 15- to 19-year (87%) age groups. Based on International Classification of Disease-9th Revision classification, 29% of concussions were associated with some form of loss of consciousness. Finally, 56% of concussions were diagnosed in the emergency department and 29% in a physician's office, with the remainder in urgent care clinics or inpatient settings. The incidence of concussion diagnosed in the general US population is increasing, driven largely by a substantial rise in the adolescent
Full Text Available Introduction: This commentary provides the rationale and makes a call for greater investment and effort to meet the sexual and reproductive health (SRH problems of adolescent girls living with HIV in low- and middle-income countries (LMIC. Discussion: Adolescent girls in LMIC are at a greater risk of acquiring HIV infection than their male peers. They also face a number of other serious SRH problems – early pregnancy, pregnancy- and childbirth-related complications, unsafe abortions, sexual abuse and intimate partner violence and sexually transmitted infections. While many LMIC have made notable progress in preventing HIV in children and adults and in improving the access of these population groups to HIV treatment and care, adolescents in general and adolescent girls in particular have not received the same effort and investment. Conclusions: Much more needs to be done to implement proven approaches to prevent new HIV infections in adolescent girls in LMIC and to meet the needs of those living with HIV.

Full Text Available OBJECTIVE: To describe the prevalence of headache and its interference in the activities of daily living (ADL in female adolescent students.METHODS: This descriptive cross-sectional study enrolled 228 female adolescents from a public school in the city of Petrolina, Pernambuco, Northeast Brazil, aged ten to 19 years. A self-administered structured questionnaire about socio-demographic characteristics, occurrence of headache and its characteristics was employed. Headaches were classified according to the International Headache Society criteria. The chi-square test was used to verify possible associations, being significant p<0.05.RESULTS: After the exclusion of 24 questionnaires that did not met the inclusion criteria, 204 questionnaires were analyzed. The mean age of the adolescents was 14.0±1.4 years. The prevalence of headache was 87.7%. Of the adolescents with headache, 0.5% presented migraine without pure menstrual aura; 6.7%, migraine without aura related to menstruation; 1.6%, non-menstrual migraine without aura; 11.7%, tension-type headache and 79.3%, other headaches. Significant associations were found between pain intensity and the following variables: absenteeism (p=0.001; interference in ADL (p<0.001; medication use (p<0.001; age (p=0.045 and seek for medical care (p<0.022.CONCLUSIONS: The prevalence of headache in female adolescents observed in this study was high, with a negative impact in ADL and school attendance.

Full Text Available The influence of family relationships on adolescents' behavior and development has been widely investigated. This study examines the relationship between family structure and a adolescents' quality of experience in daily activities and social contexts b adolescents' perceived life influences, challenges and goals. To achieve this aim, Flow Questionnaire and Life Theme Questionnaire were administered to 50 Italian girls (15-21 years of age, 25 living in two-parent families, 25 entrusted to Institutions for Custody of Minors. The findings suggest tha adolescents' perception of a positive and supportive family enviroment fosters the active search for challenges and enjoyment in daily activities, and the involvement in productive and social contexts. On the contrary , negative family perception is related to lack of engagement and motivation, and to the prevalence of low-challenge activities as sources of enjoyment and satisfaction. Although the sample size does not allow us to draw conclusions about causality, the results confirm the crucial role of family in influencing adolescents' psychological and behavioral development.

Traditionally, people have inhabited places with ready access to fresh water. Today, over 50% of the global population lives in urban areas, and water can be directed via tens of kilometres of pipelines. Still, however, a large part of the world's population is directly dependent on access to natural freshwater sources. So how are inhabited places related to the location of freshwater bodies today? We present a high-resolution global analysis of how close present-day populations live to surface freshwater. We aim to increase the understanding of the relationship between inhabited places, distance to surface freshwater bodies, and climatic characteristics in different climate zones and administrative regions. Our results show that over 50% of the world's population lives closer than 3 km to a surface freshwater body, and only 10% of the population lives further than 10 km away. There are, however, remarkable differences between administrative regions and climatic zones. Populations in Australia, Asia, and Europe live closest to water. Although populations in arid zones live furthest away from freshwater bodies in absolute terms, relatively speaking they live closest to water considering the limited number of freshwater bodies in those areas. Population distributions in arid zones show statistically significant relationships with a combination of climatic factors and distance to water, whilst in other zones there is no statistically significant relationship with distance to water. Global studies on development and climate adaptation can benefit from an improved understanding of these relationships between human populations and the distance to fresh water.
Full Text Available The objective of the study was to determine the similarities and differences between adolescents with psychoactive substances use experience living in urban and rural areas as regards the intensity of Internet addiction symptoms as well as the evaluation of prevalence of psychoactive substances use among adolescents depending on the place of residence. The examined group consisted of 1 860 people (1 320 girls and 540 boys their average age being 17 years. In the study the following research methods were used: the Sociodemographic Questionnaire designed by the authors, the Internet Addiction Questionnaire by Potembska, the Internet Addiction test by Young, the Internet Addiction Questionnaire (KBUI designed by Pawłowska and Potembska. Statistically significant differences were found as regards the prevalence of psychoactive substances use by the adolescents living in urban and rural areas and as regards the intensity of Internet addiction symptoms in adolescents, both from the urban and rural areas, who use and do not use illegal drugs. Significantly more adolescents living in urban areas as compared to their peers living in rural areas use psychoactive substances, mainly marihuana. The adolescents who use psychoactive substances, as compared to the adolescents with no experience using illegal drugs, living both in urban and rural areas significantly more often play online violent games and use web pornography. The adolescents living in rural areas who use psychoactive substances significantly more often as compared to the adolescents who do not use these substances claim that it is only thanks to the interactions established on the Internet that they can get acceptance, understanding and appreciation.

We investigated the prevalence of juvenile weapon carrying and psychosocial and personality-related risk factors for carrying different types of weapons in a nationally representative, population-based sample of Finnish adolescents. Specifically, we aimed to investigate psychopathic-like personality features as a risk factor for weapon carrying. The participants were 15-16-year-old adolescents from the Finnish self-report delinquency study (n = 4855). Four different groups were formed based on self-reported weapon carrying: no weapon carrying, carrying knife, gun or other weapon. The associations between psychosocial factors, psychopathic-like features and weapon carrying were examined with multinomial logistic regression analysis. 9% of the participants had carried a weapon in the past 12 months. Adolescents with a history of delinquency, victimization and antisocial friends were more likely to carry weapons in general; however, delinquency and victimization were most strongly related to gun carrying, while perceived peer delinquency (antisocial friends) was most strongly related to carrying a knife. Better academic performance was associated with a reduced likelihood of carrying a gun and knife, while feeling secure correlated with a reduced likelihood of gun carrying only. Psychopathic-like features were related to a higher likelihood of weapon carrying, even after adjusting for other risk factors. The findings of the study suggest that adolescents carrying a weapon have a large cluster of problems in their lives, which may vary based on the type of weapon carried. Furthermore, psychopathic-like features strongly relate to a higher risk of carrying a weapon.

Each year, around 50.000 children in Sweden experience a separation between their parents. Joint physical custody (JPC), where the child alternates homes between the parents for about equal amount of time, has become a common living arrangement after parental separation. Children in two homes could benefit from everyday contact with both parents and access to both parents' financial resources. However, children could experience stress from being constantly moving and potentially exposed to parental conflicts. Still, studies on JPC and biological functioning related to stress, are lacking. The aim of this study was to investigate how living arrangements (intact family/JPC) relate to HPA-axis activity and recurrent pain in mid-adolescents. Mid-adolescents (106 girls and 51 boys) provided demographic details, self-reports of recurrent pain (headache, stomachache, neck/shoulder and back pain) and salivary samples. Salivary cortisol samples were collected: 1) immediately at awakening, 2) +30 minutes, 3) +60 minutes, and 4) at 8 p.m. The cortisol awakening response (CAR) was computed using an established formula. Additionally, the diurnal decline between the waking and 8 p.m. samples was computed. Hierarchical multiple regressions showed that living arrangements (intact family/JPC) was not associated with morning cortisol (CAR), the diurnal cortisol decline or with recurrent pain. However, sex was a significant predictor of both cortisol measures and recurrent pain with girls exhibiting a higher cortisol awakening response and a greater diurnal decline value as well as reporting more recurrent pain than did boys. Living arrangements were not associated with HPA-axis activity or recurrent pain in this group of well-functioning mid-adolescents. Although this study is the first to investigate how living arrangements relate to HPA-axis functioning and additional studies are needed, the tentative findings suggest that these mid-adolescents have adapted to their living

Full Text Available Abstract Background In adult research, neighborhood walkability has been acknowledged as an important construct among the built environmental correlates of physical activity. Research into this association has only recently been extended to adolescents and the current empirical evidence is not consistent. This study investigated whether neighborhood walkability and neighborhood socioeconomic status (SES are associated with physical activity among Belgian adolescents and whether the association between neighborhood walkability and physical activity is moderated by neighborhood SES and gender. Methods In Ghent (Belgium, 32 neighborhoods were selected based on GIS-based walkability and SES derived from census data. In total, 637 adolescents (aged 13-15 year, 49.6% male participated in the study. Physical activity was assessed using accelerometers and the Flemish Physical Activity Questionnaire. To analyze the associations between neighborhood walkability, neighborhood SES and individual physical activity, multivariate multi-level regression analyses were conducted. Results Only in low-SES neighborhoods, neighborhood walkability was positively associated with accelerometer-based moderate to vigorous physical activity and the average activity level expressed in counts/minute. For active transport to and from school, cycling for transport during leisure time and sport during leisure time no association with neighborhood walkability nor, with neighborhood SES was found. For walking for transport during leisure time a negative association with neighborhood SES was found. Gender did not moderate the associations of neighborhood walkability and SES with adolescent physical activity. Conclusions Neighborhood walkability was related to accelerometer-based physical activity only among adolescent boys and girls living in low-SES neighborhoods. The relation of built environment to adolescent physical activity may depend on the context.
Full Text Available Objectives: This study compares the adherence of immigrant and Spanish adolescents residing in the Madrid region (Spain to national dietary recommendations. The factors compared were the consumption of items from the eight basic food groups (vegetables, fruits, bread/cereals, meat, eggs, fish, legumes and milk/dairy products, including the excessive or deficient consumption of eggs, meat and fish. In addition, the evaluation of excessive sweet foods or soft drinks in the diet was also considered. Subsequently, the influence of length of residence on dietary habits was examined. Materials and methods: Self-reported data were collected in a cross-sectional survey conducted over the period November 2007 to February 2008. The study participants were a representative sample of adolescents aged 13 to 17 years (n = 2,081, 1,055 girls living in the Madrid region. Participants were recruited from secondary schools (grades 7th to 10th randomly selected according to the geographic distribution of adolescents in the region. Results: Immigrant adolescents showed a greater likelihood of not fulfilling recommendations for the consumption of meat, fish, eggs, legumes, bread/cereals, and milk/dairy products. Their diets were also more likely to lack sufficient fish and they also consumed more eggs and more sweet foods and soft drinks than their native counterparts. Spanish adolescents were more likely not to meet recommendations for the intake of vegetables. Length of residence weakly affected dietary habits, with both negative and positive effects observed. Conclusion: The likelihood of not fulfilling dietary recommendations was higher among the immigrant adolescents with the exception of the intake of fruits and vegetables.

Cyberbullying, threatening or harassing another via the internet or mobile phones, does not cause physically harm and thus the consequences are less visible. Little research has been performed on the occurrence of cyberbullying among adolescents or the perception of its seriousness. Only a few population-based studies have been published, none of which included research on the witnessing of cyberbullying. Here, we examined exposure to cyberbullying during the last year, and its frequency and perceived seriousness among 12 to 18-year-old adolescents in Finland. We studied four dimensions of cyberbullying: being a victim, bully, or both victim and bully of cyberbullying, and witnessing the cyberbullying of friends. Self-administered questionnaires, including four questions on cyberbullying, were mailed to a representative sample of 12-, 14-, 16-, and 18-year-old Finns in 2009 (the Adolescent Health and Lifestyle Survey). The respondents could answer via the internet or paper questionnaire. The number of respondents was 5516 and the response rate was 56%. Girls more often than boys reported experiencing at least one dimension of cyberbullying during the last year. The proportion was highest among 14-year-olds and lowest among 18-year-olds of both sexes. Among girls, the most commonly encountered dimension was witnessing the cyberbullying of friends (16%); and being a victim was slightly more common than being a bully (11% vs. 9%). Among boys, an equal proportion, approximately 10%, had been a victim, a bully, or had witnessed cyberbullying. The proportion of bully-victims was 4%. Serious and disruptive cyberbullying was experienced by 2% of respondents and weekly cyberbullying by 1%; only 0.5% of respondents had been bullied weekly and considered bullying serious and disruptive. Adolescents are commonly exposed to cyberbullying, but it is rarely frequent or considered serious or disruptive. Cyberbullying exposure differed between sexes, such that girls more often than

To assess the prevalence of physical inactivity among adolescents with HIV/AIDS, as well as associated factors. Ninety-one adolescents (from 10 to 19 years old) with HIV/AIDS who are patients at a university follow-up service were interviewed. Anthropometric data (weight, height, and waist circumference) were measured twice; clinical information was obtained from medical records, and habitual physical activity was assessed by a questionnaire proposed by Florindo et al. The cutoff point for sedentariness was 300minutes/week. The prevalence of inadequate height for age, malnutrition, and overweight/obesity was 15.4%, 9.9% and 12.1%, respectively. The most common physical activities were soccer (44.4%), volleyball (14.4%) and cycling (7.8%). The median times spent with physical activity and walking/bicycling to school were 141minutes and 39minutes, respectively. Most adolescents (71.4%) were sedentary and this proportion was higher among girls (p=0.046). A high prevalence of physical inactivity among adolescents with HIV/AIDS was observed, similarly to the general population. Promoting physical activity among adolescents, especially among girls with HIV/AIDS, as well as monitoring it should be part of the follow-up routine of these patients.

Abstract Objective: to evaluate the quality of health care for children and adolescents living with HIV, among the different types of Primary Health Care services of Santa Maria, Rio Grande do Sul. Method: cross-sectional study, developed with 118 Primary Health Care professionals. The Primary Care Evaluation Instrument, Professional version, was used. For verification of the variables associated with the high score, Poisson Regression was used. Results: the professionals of the Family Health Strategy, when compared to those of the Primary Health Units, obtained a greater degree of orientation to primary care, both for the overall score and for the derived attributes score, as well as for the integrality and community orientation attributes. A specialization in Primary Health Care, other employment and a statutory work contract were associated with quality of care. Conclusion: the Family Health Strategy was shown to provide higher quality health care for children and adolescents living with HIV, however, the coverage is still low. The need was highlighted to expand this coverage and invest in vocational training directed toward Primary Care and making the professionals effective, through public selection procedure, as well as an improvement program that recognizes the care requirements, in these settings, of children and adolescents infected with HIV.

This study explored post-migration experiences of recently migrated Pakistani Muslim adolescent females residing in the United States. In-depth, semi-structured interviews were conducted with thirty Pakistani Muslim adolescent females between the ages of 15 and 18 years living with their families in Houston, Texas. Data obtained from the interviews were evaluated using discourse analysis to identify major reoccurring themes. Participants discussed factors associated with the process of adaptation to the American culture. The results revealed that the main factors associated with adaptation process included positive motivation for migration, family bonding, social support networks, inter-familial communication, aspiration of adolescents to learn other cultures, availability of English-as-second-language programs, participation in community rebuilding activities, and faith practices, English proficiency, peer pressure, and inter-generational conflicts. This study provided much needed information on factors associated with adaptation process of Pakistani Muslim adolescent females in the United States. The results have important implications for improving the adaptation process of this group and offer potential directions for intervention and counseling services.

Adolescence is a critical life-stage that sets the foundation for health in adulthood. Adolescent women are a unique population and should be targeted as such for nutrition promotion activities. Using Indonesia as a case study, this qualitative study aimed to identify existing nutrition promotion programs aimed at adolescent girls, how best to target this population and effective recommendations to inform nutrition education program design for this important group. Semi-structured interviews and questionnaires were conducted with ten key informants working in public health in Indonesia. Interview transcripts were analysed and coded to identify key themes. No existing nutrition education programs targeting adolescent women in Indonesia were identified. Several strategies apply to nutrition programs for adolescent girls: 1) nutrition promotion messages that are relevant to the lifestyles and interests of adolescent women; 2) technology-based interventions show promise, however, they need to be appropriately targeted to sub-groups; 3) school remains an important setting; and 4) early marriage is an important issue affecting nutritional status and engagement of adolescent girls. The informants recommended that: 1) more research is needed about the underlying motivations for behaviour change among adolescent women and ways to effectively implement the identified engagement strategies; 2) adolescent girls should be included in program design to improve its suitability and uptake; and 3) government budget and policy support is crucial to success. Adolescent women are an important population group and more research is required to identify the optimal forms of engagement to improve nutrition programs for them.

Although Web-based treatments have significant potential to assess and treat difficult-to-reach populations, such as trauma-exposed adolescents, the extent that such treatments are accessed and used is unclear. The present study evaluated the proportion of adolescents who accessed and completed a Web-based treatment for postdisaster mental health symptoms. Correlates of access and completion were examined. A sample of 2,000 adolescents living in tornado-affected communities was assessed via structured telephone interview and invited to a Web-based treatment. The modular treatment addressed symptoms of posttraumatic stress disorder, depression, and alcohol and tobacco use. Participants were randomized to experimental or control conditions after accessing the site. Overall access for the intervention was 35.8%. Module completion for those who accessed ranged from 52.8% to 85.6%. Adolescents with parents who used the Internet to obtain health-related information were more likely to access the treatment. Adolescent males were less likely to access the treatment. Future work is needed to identify strategies to further increase the reach of Web-based treatments to provide clinical services in a postdisaster context. (c) 2015 APA, all rights reserved).

Studies investigating the life satisfaction of intellectually gifted and non-gifted students are scarce and often suffer from methodological shortcomings. We examined the life satisfaction of gifted and non-gifted adolescents using a rather unselected sample of N = 655 German high-school students (n = 75 gifted), adequate comparison groups of non-gifted students, and a clear definition of giftedness (general intelligence g > 2 SD above the mean). There was no difference in life satisfaction between gifted and non-gifted adolescents (d giftedness but was instead found across the entire sample. Thus, gifted girls were not found to be especially unsatisfied with their lives. Our findings support previous research showing that giftedness is not a risk factor for impaired psycho-social well-being of boys or girls.

Background Activity limitations are an important and useful dimension of disability, but there are few validated measures of activity limitations for adolescents and adults with developmental disabilities. Objective/Hypothesis To describe the development of the Waisman Activities of Daily Living (W-ADL) Scale for adolescents and adults with developmental disabilities, and systematically evaluate its measurement properties according to an established set of criteria. Methods The W-ADL was administered among four longitudinally-studied groups of adolescents and adults with developmental disabilities: 406 with autism; 147 with fragile-X syndrome; 169 with Down syndrome, and 292 with intellectual disability of other or unknown origin. The W-ADL contains 17 activities and each is rated on a 3-point scale (0=“does not do at all”, 1=“does with help”, 2=“independent”), and a standard set of criteria were used to evaluate its measurement properties. Results Across the disability groups, Cronbach’s alphas ranged from 0.88 to 0.94, and a single-factor structure was most parsimonious. The W-ADL was reliable over time, with weighted kappas between 0.92 and 0.93. Criterion and construct validity were supported through substantial associations with the Vineland Screener, need for respite services, caregiving burden, and competitive employment. No floor or ceiling effects were present. There were significant group differences in W-ADL scores by maternally-reported level of intellectual disability (mild, moderate, severe, profound). Conclusions The W-ADL exceeded the recommended threshold for each quality criterion the authors evaluated. This freely-available tool is an efficient measure of activities of daily living for surveys and epidemiological research concerning adolescents and adults with developmental disabilities.

Background: Peru is experiencing a stage of nutritional transition where the principal characteristics are typical of countries undergoing development. Objectives: The objectives of this study were the following: (a) compare physical growth patterns with an international standard; (b) determine biological age; and (c) analyze the double nutritional burden of adolescents living at a moderate altitude in Peru. Design: Weight, standing height, and sitting height were measured in 551 adolescents of both sexes (12.0 to 17.9 years old) from an urban area of Arequipa, Peru (2328 m). Physical growth was compared with the international standard of the CDC-2000. Biological age was determined by using a non-invasive transversal technique based on years from age at peak height velocity (APHV). Nutritional state was determined by means of weight for age and height for age. Z scores were calculated using international standards from the CDC-2000. Results: Body weight for both sexes was similar to the CDC-2000 international standards. At all ages, the girls’ height (p < 0.05) was below the standards. However, the boys’ height (p < 0.05) was less at ages, 15, 16, and 17. Biological age showed up in girls at age 12.7 years and for boys at 15.2 years. Stunted growth (8.7% boys and 18.0% girls) and over weight (11.3% boys and 8.8% girls) occurred in both groups. A relationship existed in both sexes between the categories of weight for the age and stunted growth by sex. Conclusions: Adolescents living at a moderate altitude exhibited stunted linear growth and biological maturation. Furthermore, adolescents of both sexes showed the presence of the double nutritional burden (stunted growth and excessive weight). PMID:26404334

Daily living skills standard scores on the Vineland Adaptive Behavior Scales-2nd edition were examined in 417 adolescents from the Simons Simplex Collection. All participants had at least average intelligence and a diagnosis of autism spectrum disorder. Descriptive statistics and binary logistic regressions were used to examine the prevalence and predictors of a "daily living skills deficit," defined as below average daily living skills in the context of average intelligence quotient. Approximately half of the adolescents were identified as having a daily living skills deficit. Autism symptomatology, intelligence quotient, maternal education, age, and sex accounted for only 10% of the variance in predicting a daily living skills deficit. Identifying factors associated with better or worse daily living skills may help shed light on the variability in adult outcome in individuals with autism spectrum disorder with average intelligence.

Background Saudi Arabia has passed through lifestyle changes toward unhealthy dietary patterns such as high fast food consumption. Adolescents and young adults, particularly girls, are the main groups exposed to and affected by these adverse eating behaviors. Objective The aim of this study was to examine the trends of fast food consumption among adolescent and young adult Saudi girls living in Riyadh, and to compare between them. Design In a cross-sectional survey, 127 adolescent Saudi girls (13–18 years) and 69 young adult Saudi girls (19–29 years) were randomly recruited to participate in this study. Weight, height, waist circumference, and hip circumference were measured using standardized methods. Twenty-four-hour diet recall and a face-to-face interview food questionnaire were performed. Results Most of the participants had adequate intake of protein, riboflavin, iron, and sodium, but exhibited low intake for several other nutrients. Among study participants, 95.4% consume restaurants’ fast food and 79.1% eat fast food at least once weekly. Burgers and carbonated soft drinks were the main kinds of fast food meals and beverages usually eaten by girls. Adolescent girls who usually ate large portion sizes of fast food had significantly higher mean waist circumference and hip circumference. Participants eat fast food primarily for enjoying the delicious taste, followed by convenience. Restaurants’ hygiene and safety standards were the main concern regarding fast food for 62.2% of girls. Finally, international restaurants were preferable by participants to buy fast food compared with local restaurants (70.9% vs. 29.1%). Conclusion Our findings provide evidence on the high prevalence of fast food consumption among Saudi girls, suggesting an urgent need for community-based nutrition interventions that consider the trends of fast food consumption and targeted eating behaviors of adolescent and young adult girls.

Background Long-range oscillations of the mammalian cell proliferation rate are commonly observed both in vivo and in vitro. Such complicated dynamics are generally the result of a combination of stochastic events and deterministic regulation. Assessing the role, if any, of chaotic regulation is difficult. However, unmasking chaotic dynamics is essential for analysis of cellular processes related to proliferation rate, including metabolic activity, telomere homeostasis, gene expression, and tumor growth. Methodology/Principal Findings Using a simple, original, nonlinear method based on return maps, we previously found a geometrical deterministic structure coordinating such fluctuations in populations of various cell types. However, nonlinearity and determinism are only necessary conditions for chaos; they do not by themselves constitute a proof of chaotic dynamics. Therefore, we used the same analytical method to analyze the oscillations of four well-known, low-dimensional, chaotic oscillators, originally designed in diverse settings and all possibly well-adapted to model the fluctuations of cell populations: the Lorenz, Rössler, Verhulst and Duffing oscillators. All four systems also display this geometrical structure, coordinating the oscillations of one or two variables of the oscillator. No such structure could be observed in periodic or stochastic fluctuations. Conclusion/Significance Theoretical models predict various cell population dynamics, from stable through periodically oscillating to a chaotic regime. Periodic and stochastic fluctuations were first described long ago in various mammalian cells, but by contrast, chaotic regulation had not previously been evidenced. The findings with our nonlinear geometrical approach are entirely consistent with the notion that fluctuations of cell populations can be chaotically controlled. PMID:20179755

The author has found that time-averaged images of small populations of point vortices can exhibit motions suggestive of the behavior of individual organisms. As an example, the author shows that collections of point vortices confined in a box and subjected to heating can generate patterns that are broadly similar to interspecies defense in certain sea anemones. It is speculated that other simple dynamical systems can be found to produce similar complex organism-like behavior.

Living in Roma settlements is associated with worse health in comparison with the majority population; this might be partially explained by socioeconomic disadvantages as well as cultural differences, including lifestyle. Eating habits represent an important part of lifestyle closely related to primary causes of morbidity and mortality, such as cardiovascular diseases, metabolic diseases or cancers. The eating habits of the population living in Roma settlements in comparison with those of the majority population were explored using the cross-sectional epidemiological HepaMeta study conducted in 2011. A representative sample of Roma (n = 452, mean age = 34.7; 35.2% men) and non-Roma (n = 403, mean age = 33.5; 45.9% men) aged 18-55 years living in the Kosice region were asked about breakfasting and recent consumption of fruits, vegetables, dairy products, meat products, meat, farinaceous dishes, and soft drinks. A logistic regression model was used separately for male and female participants. The population living in Roma settlements reported the recent consumption of fruit, vegetables and dairy products significantly less frequently in comparison with the majority population. Moreover, Roma females, in comparison with non-Roma females, reported significantly more frequently the consumption of meat and soft drinks. No differences were found between Roma and non-Roma in the consumption of meat products and farinaceous dishes. The population living in Roma settlements reported more frequently unhealthy eating habits in comparison with the majority population; this might contribute to worse health status of this population. The differences might be attributed to cultural differences between ethnic as well as socioeconomic groups, reduced availability of certain food items due to segregation or poverty and lower health literacy.

The present study examined the development of knowledge about rights from childhood to adolescence. One hundred and sixty-nine 8-16-year-olds participated in individual semi-structured interviews assessing knowledge and importance of rights both generally and in children's and adolescents' lives. Detailed content analyses indicated that a global stage account may not capture key features of the development of young people's knowledge about rights. Even the oldest adolescents consistently "defined" rights in concrete rather than abstract terms. In contrast, by 10 years of age the majority of subjects were aware of the universal nature of rights. These results suggest that what adolescents and children think about rights appears to be influenced by how they view rights in their own lives. The findings are discussed in terms of developmental theory and in relation to practical implications for children's rights.
In 1951 the Indian population arrived at the end of its period of slow growth associated with British colonial rule. The mortality rate was still high at 27-31/1000; with a birth rate of 41-43/1000, the annual rate of growth was 1.2-1.3%. In the following decade, mortality declined appreciably due to progress in medicine and public health, but after 1961 the mortality decline slowed. Fertility began to decline, but much more slowly than hoped. The rate of urbanization was more moderate than in many developing countries, and the sex ratio for reasons not well understood continued to favor males. The rate of increase in several states slowed between 1961-71, and it appeared plausible that declining natality was a factor. The proportion literate increased from 24.03% in 1961 to 36.17% in 1981. In 1981, 46.74% of men and 24.88% of women were literate. Between 1951-81, mortality declined from 27-31/1000 to 13/1000 while fertility declined from 41-43/1000 to 34/1000. The effects of the future fertility decline will be partially offset by declining mortality. Although India has had some kind of family planning program since the 5-Year Plan of 1951-56, progress has been slow and uneven. Concern about overpopulation is increasing among the population, but available methods of contraception are imperfect, many programs are poorly administered, and skilled personnel are in short supply. The age at marriage has increased somewhat but not enough to have a major impact on fertility. Despite the extreme difficulty of establishing the caloric intake and real incomes of the poorest classes, it is known that wide disparities of income existed before independence and that population growth began to outpace increases in agricultural production long ago in some regions. However, after independence food production in the country as a whole increased by 114.3% while population increased by 93.7%. Growth of agricultural productivity has subsequently slowed. Improvements have been unevenly

In this study we investigate whether there are differences between adolescents who grow up in single-parent families and those who grow up in nucleus families. We have decided that there are no differences in the physical development between the adolescents who are growing up in single parent families and those growing up in nucleus families. There is no difference in the self-concept between these two groups, except in the ethical and moral self-image of adolescents living with one parent. A...

Full Text Available Objectives: This study was designed to compare the risk of having an eating disorder (ED among immigrant and native adolescents living in Madrid and to determine the possible influence of length of residence (LOR on the risk of the immigrants. Methods: A cross-sectional survey was conducted from november 2007 to february 2008 in a representative sample of adolescents aged 13 to 17 years (n = 2,077, 1,052 girls living in the Madrid region. Data were collected using the Spanish version of the SCOFF Eating Disorders Questionnaire. Further factors considered were country of birth, LOR and several biological, sociodemographic, lifestyle and health-related variables. Results: According to the three logistic regression models constructed, female immigrant adolescents on the whole showed a greater ED risk (OR = 1.95; 95%CI 1.292.95; p = 0.001 than native adolescents. Moreover, the likelihood of ED was higher among female immigrants living in Spain for <6 years than for Spanish native females (OR = 2.44; 95%CI 1.42-4.18; p = 0.001, while no significant differences were found when female natives were compared with female immigrants living in this country for ≥ 6 years. Similarly, no differences were observed in the ED risk recorded for male native and immigrant adolescents, both as a whole and by length of residence in Spain. Conclusions: The immigrant status and the length of Spanish residence are relevant factors in regard to the ED risk in adolescents living in Madrid.

Internalized HIV stigma is a key risk factor for negative outcomes amongst adolescents living with HIV (ALHIV), including non-adherence to anti-retroviral treatment, loss-to-follow-up and morbidity. This study tested a theoretical model of multi-level risk pathways to internalized HIV stigma among South African ALHIV. From 2013 to 2015, a survey using total population sampling of ALHIV who had ever initiated anti-retroviral treatment (ART) in 53 public health facilities in the Eastern Cape, South Africa was conducted. Community-tracing ensured inclusion of ALHIV who were defaulting from ART or lost to follow-up. 90.1% of eligible ALHIV were interviewed (n = 1060, 55% female, mean age = 13.8, 21% living in rural locations). HIV stigma mechanisms (internalized, enacted, and anticipated), HIV-related disability, violence victimization (physical, emotional, sexual abuse, bullying victimization) were assessed using well-validated self-report measures. Structural equation modelling was used to test a theoretically informed model of risk pathways from HIV-related disability to internalized HIV stigma. The model controlled for age, gender and urban/rural address. Prevalence of internalized HIV stigma was 26.5%. As hypothesized, significant associations between internalized stigma and anticipated stigma, as well as depression were obtained. Unexpectedly, HIV-related disability, victimization, and enacted stigma were not directly associated with internalized stigma. Instead significant pathways were identified via anticipated HIV stigma and depression. The model fitted the data well (RMSEA = .023; CFI = .94; TLI = .95; WRMR = 1.070). These findings highlight the complicated nature of internalized HIV stigma. Whilst it is seemingly a psychological process, indirect pathways suggest multi-level mechanisms leading to internalized HIV stigma. Findings suggest that protection from violence within homes, communities and schools may interrupt risk pathways from HIV

Measles is a disease predominantly seen in young children and infants. It is an unusual occurrence of the disease in the adolescent population warranting an investigation. This would help understand the possible cause-effect relation, changing epidemiology of the disease and immunity gaps to initiate targeted interventional strategies. To determine the time, place and person distribution of an outbreak and calculate the attack rates and vaccine efficacy. Investigation of an outbreak was conducted by an emergency rapid response team following the report of a case of measles on 18th November 2013, in and around the campus of the study university in search of suspects and undetected cases. W.H.O developed standard outbreak investigation formats, were used for obtaining the data. The subjects were chosen by purposive sampling. All the contacts of the cases were approached along with a house to house survey in the surrounding residential area for active case finding. Measles was clinically diagnosed based on the standard case definition of measles as per the WHO guidelines and confirmed through measurement of measles specific IgM antibody levels in the serum of suspected/clinically confirmed cases. The outbreak lasted for duration of six weeks during which a total of 20 laboratory confirmed cases were found. Most of the cases were in the age group of 21-25 years. The overall attack rate was 3.5% and vaccine efficacy was calculated to be 75%. There is an epidemiological shift in the age of occurrence of measles in the region among students coming from various regions of the country staying predominantly in hostels.

Adolescents living with HIV (ALHIV) face many psychosocial challenges, including HIV disclosure to others. Given the importance of socialization during the adolescent transition process, this study investigated the psychological and social factors influencing self-disclosure of own HIV status to peers. We examined social HIV self-disclosure to peers, and its relationship to perceived HIV-related stigma, self-efficacy to disclose, self-esteem, and social support among a sample of n = 582 ALHIV aged 13-17 years in Kampala, Uganda, and Western Kenya. Data were collected between February and April 2011. Among them, 39% were double orphans. We conducted a secondary data analysis to assess the degree of social disclosure, reactions received, and influencing factors. Interviewer-administered questionnaires assessed medical, socio-demographic, and psychological variables (Rosenberg self-esteem scale; self-efficacy to disclose to peers), HIV-related stigma (10-item stigma scale), and social support (family-life and friends). Descriptive, bivariate, and logistic regression analyses were performed with social self-disclosure to peers with gender as covariates. Almost half of ALHIV had told nobody (except health-care providers) about their HIV status, and about 18% had disclosed to either one of their friends, schoolmates, or a boy- or girlfriend. Logistic regression models revealed that having disclosed to peers was significantly related to being older, being a paternal orphan, contributing to family income, regular visits to the HIV clinic, and greater social support through peers. Low self-efficacy to disclose was negatively associated to the outcome variable. While social self-disclosure was linked to individual factors such as self-efficacy, factors relating to the social context and adolescents' access to psychosocial resources play an important role. ALHIV need safe environments to practice disclosure skills. Interventions should enable them to make optimal use of
Full Text Available Adolescence is a developmental period that implies a series of rapid changes that might complicate the role of parents. This study evaluates changes in parental monitoring and the strategies to solve family conflicts reported by parents who participated in the "Living Adolescence in Family" program in local social services and school centers. In addition, the study analyses the moderating role of family and facilitator variables that may affect the final results. The participants were 697 parents attending the social services (438 in the intervention group and 259 in the control group and 1283 parents from school centers (880 in the intervention group and 403 in the control group. The results showed that families from local social services decreased the amount of control and improved monitoring in education and leisure spheres as well as self-disclosure whereas the families coming from school centers improved supervision in leisure and in self-disclosure. In addition, both groups of families improved their strategies for solving family conflicts, increasing the use of integrative strategies and decreasing the use of dominant strategies. There were differences across contexts: the results of the program in the social services context differed according to the participant and professional profiles whereas program results were more homogeneous in the school context. In sum, the program appears to be an efficient work tool, both for the professionals who work with at-risk families with adolescents and for the teachers who make use of the program for families with children at risk of early school dropout.

Living kidney donation is declining in the United States. We examined longitudinal trends in living donation as a function of median household income and donor relation to assess the effect of financial barriers on donation in a changing economic environment. The zip code-level median household income of all 71,882 living donors was determined by linkage to the 2000 US Census. Longitudinal changes in the rate of donation were determined in income quintiles between 1999 and 2004, when donations were increasing, and between 2005 and 2010, when donations were declining. Rates were adjusted for population differences in age, sex, race, and ESRD rate using multilevel linear regression models. Between 1999 and 2004, the rate of growth in living donation per million population was directly related to income, increasing progressively from the lowest to highest income quintile, with annualized changes of 0.55 (95% confidence interval [95% CI], 0.14 to 1.05) for Q1 and 1.77 (95% CI, 0.66 to 2.77) for Q5 (Pincome with longitudinal changes also varied by donor relationship. In conclusion, changes in living donation in the past decade varied by median household income, resulting in increased disparities in donation between low- and high-income populations. These findings may inform public policies to support living donation during periods of economic volatility.
Full Text Available The factors driving the composition of gut microbiota are still only partly understood but appear to include environmental, cultural, and genetic factors. In order to obtain more insight into the relative importance of these factors, we analyzed the microbiome composition in subjects of Tibetan or Han descent living at different altitudes. DNA was isolated from stool samples. Using polymerase chain reaction methodology, the 16S rRNA V1-V3 regions were amplified and the sequence information was analyzed by principal coordinates analysis and Lefse analyses. Contrasting the Tibetan and Han populations both living at the 3600 m altitude, we found that the Tibetan microbiome is characterized by a relative abundance of Prevotella whereas the Han stool was enriched in Bacteroides. Comparing the microbiome of Han stool obtained from populations living at different altitudes revealed a more energy efficient flora in samples from those living at higher altitude relative to their lower-altitude counterparts. Comparison of the stool microbiome of Tibetan herders living at 4800 m to rural Tibetans living at 3600 m altitude shows that the former have a flora enriched in butyrate-producing bacteria, possibly in response to the harsher environment that these herders face. Thus, the study shows that both altitude and genetic/cultural background have a significant influence on microbiome composition, and it represents the first attempt to compare stool microbiota of Tibetan and Han populations in relation to altitude.
Neck pain is a common health problem globally. In addition to individual suffering, it causes a huge burden on societies. Some evidence suggests that neck pain in adolescence predicts frequent neck symptoms also in adulthood. A steady increase in prevalence of frequent and persistent neck pain among Finnish adolescents was observed in the 1990s, which might predict an increasing amount of adults with chronic neck pain in the near future. Thus, better understanding neck pain in children and ad...

Full Text Available Abstract Background Identification of non-modifiable correlates of physical activity and sedentary behaviour in youth contributes to the development of effective targeted intervention strategies. The purpose of this research was to examine the relationships between family circumstances (e.g. socio-economic status, single vs. dual parent household, presence/absence of siblings and leisure-time physical activity and sedentary behaviours in adolescents. Methods A total of 1171 adolescents (40% male; mean age 14.8 years completed ecological momentary assessment diaries every 15 minutes for 3 weekdays outside of school hours and 1 weekend day. Analysed behaviours were sports/exercise, active travel, TV viewing, computer use, sedentary socialising (hanging-out, using the telephone, sitting and talking and total sedentary behaviour. Linear regression was employed to estimate levels of association between individual family circumstance variables and each behaviour. Results Compared to girls from higher socioeconomic status (SES groups, girls from low SES groups reported higher weekend TV viewing and higher weekday total sedentary behaviour. For boys, single parent status was associated with greater total sedentary behaviour compared to those from dual parent households. Boys and girls from low socio-economic neighbourhoods reported lower participation in sports/exercise compared to those living in higher socio-economic neighbourhoods. Conclusion Associations were not consistent across behaviours or between genders. Overall, findings indicate that boys from single parent households and girls from low socio-economic families may be at increased risk of high sedentary behaviour. Those living in low socioeconomic neighbourhoods may be at increased risk of reduced participation in sports and exercise.

Background Many rare diseases of childhood are life-threatening and chronically debilitating, so living with a rare disease is an on-going challenge for patients and their families. MPS is one of a range of rare inherited metabolic disorders (IMDs) that come under category 3 of life-limiting conditions, where there is no curative treatment available at present. Although the study of rare diseases is increasingly novel, and of clinical importance to the population, the lack of empirical data i...

Full Text Available Abstract Background An increasing proportion of the population lives in one-person households. The authors examined whether living alone predicts the use of antidepressant medication and whether socioeconomic, psychosocial, or behavioral factors explain this association. Methods The participants were a nationally representative sample of working-age Finns from the Health 2000 Study, totaling 1695 men and 1776 women with a mean age of 44.6 years. In the baseline survey in 2000, living arrangements (living alone vs. not and potential explanatory factors, including psychosocial factors (social support, work climate, hostility, sociodemographic factors (occupational grade, education, income, unemployment, urbanicity, rental living, housing conditions, and health behaviors (smoking, alcohol use, physical activity, obesity, were measured. Antidepressant medication use was followed up from 2000 to 2008 through linkage to national prescription registers. Results Participants living alone had a 1.81-fold (CI = 1.46-2.23 higher purchase rate of antidepressants during the follow-up period than those who did not live alone. Adjustment for sociodemographic factors attenuated this association by 21% (adjusted OR = 1.64, CI = 1.32-2.05. The corresponding attenuation was 12% after adjustment for psychosocial factors (adjusted OR = 1.71, CI = 1.38-2.11 and 9% after adjustment for health behaviors (adjusted OR = 1.74, CI = 1.41-2.14. Gender-stratified analyses showed that in women the greatest attenuation was related to sociodemographic factors and in men to psychosocial factors. Conclusions These data suggest that people living alone may be at increased risk of developing mental health problems. The public health value is in recognizing that people who live alone are more likely to have material and psychosocial problems that may contribute to excess mental health problems in this population group.

Many adolescents living in residential youth care (RYC) institutions perceive their quality of life (QoL) to be low. Enhancing QoL is thus important, but little is known about the potential contributors to their QoL. Early interpersonal trauma and subsequent removal from home and repeated relocations to new placements are expected to affect mental health and self-esteem. We therefore investigated if domain-specific self-esteem contributed to QoL among adolescents living in RYC institutions over and beyond their levels of psychopathology. All youth in Norwegian RYC institutions between the ages 12-23 years were invited to participate. Of a total of 98 RYC institutions, 86 participated, and 400 of 601 eligible youths were examined. The participants' primary contact completed the Child Behavior Checklist to assess psychopathology. The adolescents completed a revised version of the Self-Perception Profile for Adolescents and the questionnaire for measuring health-related quality of life in children and adolescents (KINDL-R). After adjusting for psychopathology, age, and gender, self-esteem domains uniquely explained 42% of the variance in Qol, where social acceptance (β = 0.57) and physical appearance (β = 0.25) domains significantly predicted concurrent QoL. The self-esteem domains, social acceptance and physical appearance, add substantially to the explained variance in QoL among adolescents living in RYC institutions, over and beyond the levels of psychopathology. These self-esteem domains may be targets of intervention to improve QoL, in addition to treating their psychopathology.

Full Text Available Background: Tumours of the breast are uncommon in childhood and adolescence. Patients in this age group often require a different approach to diagnosis and treatment. The purpose of this study is to highlight the clinicopathologic features of breast tumours in adolescents in a Nigerian city. Materials and Methods: Eighty-four breast tumour materials from patients aged 10-19 years were analyzed over a 10-year period at the Department of Pathology, University of Benin Teaching Hospital (UBTH, Benin City, Edo State, Benin City, Nigeria. Results: A majority of the breast tumours were benign. Fibroadenoma was the most common tumour with 46 cases (54.8%, followed by fibrocystic changes with 15 cases (17%. Malignancy was extremely rare in this group, with only one case (1.2% of an invasive ductal carcinoma. Histologically, most tumours were indistinguishable from the adult types. Conclusion: Fibroadenoma is the most common breast tumour in adolescents in Benin City, Nigeria. Breast cancer and male breast tumours are rare in this age group. Routine complete physical examination of children and adolescents should include breast examination.

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.

Problematic use of the mobile telephone is an emerging phenomenon in our society, and one which particularly affects the teenage population. Knowledge from research on the problematic use of this technology is necessary, since such use can give rise to a behavioural pattern with addictive characteristics. There are hardly any scales for measuring possible problematic use of mobile phones, and none at all adapted exclusively for the Spanish adolescent population. The scale most widely used internationally is the Mobile Phone Problem Use Scale (MPPUS). The aim of the present study is to adapt the MPPUS for use with Spanish adolescents. The Spanish version of the questionnaire was administered to a sample of 1132 adolescents aged 12 to 18. Reliability and factorial validity were comparable to those obtained in adult population, so that the measure of problematic mobile phone use in Spanish teenagers is one-dimensional. A prevalence of 14.8% of problematic users was detected.

HIV-infected pregnant and breastfeeding adolescents are a particularly vulnerable group that require special attention and enhanced support to achieve optimal maternal and infant outcomes. The objective of this paper is to review published evidence about antenatal care (ANC) service delivery and outcomes for HIV-infected pregnant adolescents in low-income country settings, identify gaps in knowledge and programme services and highlight the way forward to improve clinical outcomes of this vulnerable group. Emerging data from programmes in sub-Saharan Africa highlight that HIV-infected pregnant adolescents have poorer prevention of mother-to-child HIV transmission (PMTCT) service outcomes, including lower PMTCT service uptake, compared to HIV-infected pregnant adults. In addition, the limited evidence available suggests that there may be higher rates of mother-to-child HIV transmission among infants of HIV-infected pregnant adolescents. While the reasons for the inferior outcomes among adolescents in ANC need to be further explored and addressed, there is sufficient evidence that immediate operational changes are needed to address the unique needs of this population. Such changes could include integration of adolescent-friendly services into PMTCT settings or targeting HIV-infected pregnant adolescents with enhanced retention and follow-up activities.

We aimed to study the occurrence of Chlamydia trachomatis infection in the population living in Roma settlements and to compare the obtained results with the prevalence in the majority population. We examined 340 people for the presence of bacterium C. trachomatis, 208 of them were Roma (66 men, 142 women) and 132 were from the majority population (75 men, 57 women). Respondents were aged 18-55 years (mean age = 33.44, STD = 9.57). The occurence of C. trachomatis was detected by direct proof of the pathogen by polymerase chain reaction (PCR). Of 340 respondents included in the study, 22 (6.5%) showed positivity for C. trachomatis infection, 15 of them were Roma (7.2%) and 7 non-Roma (5.3%). The highest positivity was detected in Roma women (8.5%), while positivity in both non-Roma women and men was 5.3%, and in Roma men 4.5%. We did not confirm any significant contribution of age, gender or ethnicity to the occurrence of C. trachomatis infection. Despite the increased number of people with risk factors in the Roma community, no significant difference in the occurrence of C. trachomatis infection was found. Neither age nor gender contributes to the probability of C. trachomatis infection. Nevertheless, there are other health consequences which might be more pronounced among the population living in Roma settlements due to barriers to the health care and their lower ability to benefit from health care services provided.

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.

There are several indigenous ethnic populations along the silk road in the Northwest of China that display clear differences in culture and social customs, perhaps as a result of geographic isolation and different linguistic traditions. However, extensive trade and other interactions probably facilitated the admixture of different gene pools between these populations over the last two millennia. To further explore the evolutionary relationships of the 13 ethnic populations residing in Northwest China and to reveal the features of population admixture, the 9 most-commonly employed CODIS loci (D3S1358, TH01, D5S818, D13S317, D7S820, CSF1PO, vWA, TPOX, FGA) were selected for genotyping and further analysis. Phylogenetic tree and principal component analysis revealed clear pattern of population differentiation between 4 populations living in Sinkiang Uighur Autonomous Region and other 9 populations dwelled in the upper regions of Silk Road. R matrix regression showed high-level gene flow and population admixture dose exist among these ethic populations in the Northwest region of China. Furthermore, the Mantel test suggests that larger percent of genetic variance (21.58% versus 2.3%) can be explained by geographic isolation than linguistic barriers, which matched with the contribution of geographic factors to other world populations.

Spatiotemporal variation in demographic rates can have profound effects for population persistence, especially for dispersal-limited species living in fragmented landscapes. Long-term studies of plants in such habitats help with understanding the impacts of fragmentation on population persistence but such studies are rare. In this work, we reanalyzed demographic data from seven years of the short-lived cactus Opuntia macrorhiza var. macrorhiza at five plots in Boulder, Colorado. Previous work combining data from all years and all plots predicted a stable population (deterministic log lamda approximately 0). This approach assumed that all five plots were part of a single population. Since the plots were located in a suburban-agricultural interface separated by highways, grazing lands, and other barriers, and O. macrorhiza is likely dispersal limited, we analyzed the dynamics of each plot separately using stochastic matrix models assuming each plot represented a separate population. We found that the stochastic population growth rate log lamdaS varied widely between populations (log lamdaS = 0.1497, 0.0774, -0.0230, -0.2576, -0.4989). The three populations with the highest growth rates were located close together in space, while the two most isolated populations had the lowest growth rates suggesting that dispersal between populations is critical for the population viability of O. macrorhiza. With one exception, both our prospective (stochastic elasticity) and retrospective (stochastic life table response experiments) analysis suggested that means of stasis and growth, especially of smaller plants, were most important for population growth rate. This is surprising because recruitment is typically the most important vital rate in a short-lived species such as O. macrorhiza. We found that elasticity to the variance was mostly negligible, suggesting that O. macrorhiza populations are buffered against large temporal variation. Finally, single-year elasticities to means

A debate concerns whether eating disorders are increasing in prevalence. The role of socio-economic status (SES) for adolescent eating disorders (ED) is another matter of debate. To ascertain whether self-reported eating disorders or their symptoms have increased in prevalence in adolescent population from the early 2000s to early 2010s. A person-identifiable classroom survey, Adolescent Mental Health Cohort study, was carried out among the 9th graders in comprehensive schools in Tampere, Finland, during academic year 2002-2003, and replicated among then 9th graders during academic years 2012-2013. Eating disorders were elicited with questionnaires tailored according to DSM-IV criteria for anorexia nervosa and bulimia nervosa. No changes were observed between 2002-2003 and 2012-2013 in the prevalence of anorexia and bulimia, most of the symptoms of anorexia and bulimia, or the proportion of adolescents having received treatment due to eating disorders among the girls or the boys. Eating disorders, treatment contacts due to eating disorders, and eating disorder symptoms were not systematically associated with either low or high parental socio-economic status. Based on this dataset, eating disorders are not increasing in the adolescent population. Adolescent eating disorders are not associated with socio-economic status of their family.

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.

Full Text Available Quantitative study aimed to know the understanding of adolescents about their sexuality and how the exercises for further intervention by the health team. We administered a structured questionnaire in a sample of 43 adolescents aged 12 to 19 years living in the area covered by the Family Health Unit Dr. Fabio I and II. The data were tabulated in the spreadsheet program Microsoft Office Excel 2007, allowing for a descriptive treatment, keeping a confidence interval of 95%. The results show that 32.5% of participants had first intercourse between 12 and 16, and 50% of them admit they have used a condom at last intercourse. In addition, 4.6% have had some kind of sexually transmitted disease. The study indicates the need for educational activities in sexual and reproductive health to adolescents facing the neighborhoods studied, with a view to promoting health.
Full Text Available Objective: The present study is aimed to identify the most important long-term stressors for Romanian adolescents. Material and Methods: 1143 randomly selected Romanian subjects were considered. Mean age in the study sample was 15.02, with a standard deviation (SD of 0.371. About 65.4% of subjects were females. Daily hassles related to the family environment, physical state, psychological status, financial status of the family and interpersonal relationships were covered Results: 22.7% of the subjects reported daily hassles related to their familial environment, 7.8% reported daily hassles related to their physical state, 59.6% reported daily hassles related to their psychological state, 41.9% reported financial difficulties of their families and 4.4% of adolescent reported being bullied. Conclusion: Stressors that appear to be most relevant for adolescents in north-western Romania are: financial difficulties of the family and psychological difficulties. There are no differences in reporting bullying between genders and that this phenomenon is less frequent in Romania. A greater attention should be paid to the effects of workforce migration.

To determine the prevalence of hypodontia in the general population and orthodontic population in adolescent Chinese Hans. Two groups named the general population (6015 subjects) and the orthodontic population (2781 subjects) were investigated, respectively. The former came from the students of three general universities in North China and the latter came from patients coming to the Department of Orthodontics, Peking University School and Hospital of Stomatology for orthodontic consulting during the summer and winter holidays in 2008. The prevalence and average missing number of hypodontic teeth was investigated in the two groups. The distribution of missing teeth was analysed between jaw positions and between genders. The prevalence of tooth agenesis was found to be 5.89% for the general population group and 7.48% for orthodontic subjects. Tooth agenesis was more frequently found in females than in males in both of the two groups and showed a statistically significant difference (P orthodontic population. The prevalence and the number of missing teeth were higher in the orthodontic population than in the general population. Tooth agenesis showed different characteristics in the two populations. The congenital absence of the second mandibular premolars and the maxillary lateral incisors increased in the orthodontic population. Gender difference in hypodontia expressed an opposite effect in the two groups. Although tooth agenesis was more frequently found in females than in males, males missed more teeth than females in the orthodontic population. Tooth agenesis showed different characteristics between the general and orthodontic adolescent Chinese populations.

Full Text Available Abstract Background Adolescent girls are an overlooked group within conflict-affected populations and their sexual health needs are often neglected. Girls are disproportionately at risk of HIV and other STIs in times of conflict, however the lack of recognition of their unique sexual health needs has resulted in a dearth of distinctive HIV protection and prevention responses. Departing from the recognition of a paucity of literature on the distinct vulnerabilities of girls in time of conflict, this study sought to deepen the knowledge base on this issue by qualitatively exploring the sexual vulnerabilities of adolescent girls surviving abduction and displacement in Northern Uganda. Methods Over a ten-month period between 2004–2005, at the height of the Lord’s Resistance Army insurgency in Northern Uganda, 116 in-depth interviews and 16 focus group discussions were held with adolescent girls and adult women living in three displacement camps in Gulu district, Northern Uganda. The data was transcribed and key themes and common issues were identified. Once all data was coded the ethnographic software programme ATLAS was used to compare and contrast themes and categories generated in the in-depth interviews and focus group discussions. Results Our results demonstrated the erosion of traditional Acholi mentoring and belief systems that had previously served to protect adolescent girls’ sexuality. This disintegration combined with: the collapse of livelihoods; being left in camps unsupervised and idle during the day; commuting within camp perimeters at night away from the family hut to sleep in more central locations due to privacy and insecurity issues, and; inadequate access to appropriate sexual health information and services, all contribute to adolescent girls’ heightened sexual vulnerability and subsequent enhanced risk for HIV/AIDS in times of conflict. Conclusions Conflict prevention planners, resettlement programme developers, and

Full Text Available Tinea capitis is a dermatophyte infection that occurs mainly in childhood; there are few reports, in Brazil, in adolescents and adults. The detection of asymptomatic carriers is of great importance in the disease control. From February 1998 to February 1999, a study was performed at the outpatient Dermatologic Unit of Instituto de Puericultura e Pediatria Martagão Gesteira (Universidade Federal do Rio de Janeiro, Brasil to verify the frequency of asymptomatic carriers and tinea capitis between 79 adolescents, adults and elderly who lived in the same household of 56 children (0-12 years with tinea capitis. Of these, one female and one male adults (2.5% were asymptomatic carriers and the cultures revealed Trichophyton tonsurans and Microsporum canis respectively. One female adolescent and two female adults (3.8% had tinea capitis and all cultures revealed Trichophyton tonsurans. The study has shown that adolescents and adults who live in the same household of children with tinea capitis may be sick or asymptomatic carriers.

Full Text Available This study assessed and compared the daily step counts recorded by two different motion sensors in order to estimate the free-living physical activity of 135 adolescent girls. Each girl concurrently wore a Yamax pedometer and an ActiGraph accelerometer (criterion measure every day for seven consecutive days. The convergent validity of the pedometer can be considered intermediate when used to measure the step counts in free-living physical activity; but should be considered with caution when used to classify participants’ step counts into corresponding physical activity categories because of a likelihood of ‘erroneous’ classification in comparison with the accelerometer.
Conclusions: These findings highlight the complicated nature of internalized HIV stigma. Whilst it is seemingly a psychological process, indirect pathways suggest multi-level mechanisms leading to internalized HIV stigma. Findings suggest that protection from violence within homes, communities and schools may interrupt risk pathways from HIV-related health problems to psychological distress and internalized HIV stigma. This highlights the potential for interventions that do not explicitly target adolescents living with HIV but are sensitive to their needs.

A recombinant live attenuated tetravalent dengue vaccine (TDV) is safe and immunogenic in adults and children in dengue-naïve populations. Data are needed in dengue endemic populations. In a phase I, randomized, controlled, blind-observer study in the Philippines, groups of participants aged 2-5, 6-11, 12-17, and 18-45 years received either three TDV vaccinations at months 0, 3.5, and 12 (TDV-TDV-TDV group) or licensed typhoid vaccination at month 0 and TDV at months 3.5 and 12 (TyVi-TDV-TDV group) and were followed for safety (including biological safety and vaccine virus viremia) and immunogenicity. No serious adverse vaccine related events and no significant trends in biological safety parameters were reported. Injection site pain, headache, malaise, myalgia, fever, and asthenia were reported most frequently, as mild to moderate in most cases and transient. Reactogenicity did not increase with successive vaccinations and was no higher in children than in adults and adolescents. Low levels of vaccinal viremia were detected in both groups after each TDV vaccination. After three TDV vaccinations, the seropositivity rates against serotypes 1-4 were: 91%, 100%, 96%, 100%, respectively, in 2-5 year-olds; 88%, 96% 96%, 92% in 6-11 year-olds; 88%, 83%, 92%, 96% in adolescents; and 100% for all serotypes in adults. A similar response was observed after two doses for the TyVi-TDV-TDV group. The safety profile of TDV in a flavivirus endemic population was consistent with previous reports from flavivirus naïve populations. A vaccine regimen of either three TDV vaccinations administered over a year or two TDV vaccinations given more than 8 months apart resulted in a balanced antibody response to all four dengue serotypes in this flavivirus-exposed population, including children.

This method uses a photoaffinity label that recognizes DNA and can be used to distinguish populations of bacterial cells from bacterial spores without the use of heat shocking during conventional culture, and live from dead bacterial spores using molecular-based methods. Biological validation of commercial sterility using traditional and alternative technologies remains challenging. Recovery of viable spores is cumbersome, as the process requires substantial incubation time, and the extended time to results limits the ability to quickly evaluate the efficacy of existing technologies. Nucleic acid amplification approaches such as PCR (polymerase chain reaction) have shown promise for improving time to detection for a wide range of applications. Recent real-time PCR methods are particularly promising, as these methods can be made at least semi-quantitative by correspondence to a standard curve. Nonetheless, PCR-based methods are rarely used for process validation, largely because the DNA from dead bacterial cells is highly stable and hence, DNA-based amplification methods fail to discriminate between live and inactivated microorganisms. Currently, no published method has been shown to effectively distinguish between live and dead bacterial spores. This technology uses a DNA binding photoaffinity label that can be used to distinguish between live and dead bacterial spores with detection limits ranging from 109 to 102 spores/mL. An environmental sample suspected of containing a mixture of live and dead vegetative cells and bacterial endospores is treated with a photoaffinity label. This step will eliminate any vegetative cells (live or dead) and dead endospores present in the sample. To further determine the bacterial spore viability, DNA is extracted from the spores and total population is quantified by real-time PCR. The current NASA standard assay takes 72 hours for results. Part of this procedure requires a heat shock step at 80 degC for 15 minutes before the

Full Text Available Abstract Background Intake of sweet drinks has previously been associated with the development of overweight and obesity among children and adolescents. The present study aimed to assess the consumption pattern of sweet drinks in a population of children and adolescents in Victoria, Australia. Methods Data on 1,604 children and adolescents (4–18 years from the comparison groups of two quasi-experimental intervention studies from Victoria, Australia were analysed. Sweet drink consumption (soft drink and fruit juice/cordial was assessed as one day’s intake and typical intake over the last week or month at two time points between 2003 and 2008 (mean time between measurement: 2.2 years. Results Assessed using dietary recalls, more than 70% of the children and adolescents consumed sweet drinks, with no difference between age groups (p = 0.28. The median intake among consumers was 500 ml and almost a third consumed more than 750 ml per day. More children and adolescents consumed fruit juice/cordial (69% than soft drink (33% (p Conclusion The proportion of Australian children and adolescents from the state of Victoria consuming sweet drinks has been stable or decreasing, although a high proportion of this sample consumed sweet drinks, especially fruit juice/cordial at both time points.
Full Text Available Background/Aim. Proper nutrition and regular physical activity are essential parts of a adolescent's overall health. The aim of this research was to evaluated eating and physical activity behaviours and habits, nutritional and food knowledge, beliefs and self-efficacy related to diet and health of the adolescents of the city of Belgrade, Serbia. Methods. A dietary questionnaire previously constructed and tested in adolescent population from Italy was self-administrated. We evaluated eating habits, physical activity, meaning of healthy and unhealthy dietary habits and food, self-efficacy, barriers affecting food choices, nutritional and food safety, and body mass index (BMI of the adolescents. The sample included 707 adolescents, the mean age of 15,8 ± 2 years enrolled in the first grade at several high schools in Belgrade. Results. Only 27% of the adolescents had satisfactory eating habits; 31% have a very active lifestyle; 7% good nutritional knowledge and 6- 12% satisfactory food safety knowledge and hygiene practices. Conclusion. Significant deviations from recommendations for healthy lifestyle was noted in adolescents’ habits, knowledge and practice. It is therefore necessary to develop and organize programs for promotion of healthy behaviours adapted to the adolescents’ needs. [Projekat Ministarstva nauke Republike Srbije, br. III47015

Full Text Available ABSTRACT Objective: analyze trends in fertility rates and associations with perinatal outcomes for adolescents in Santa Catarina, Brazil. Methods: a population-based study covering 2006 to 2013 was carried out to evaluate associations between perinatal outcomes and age groups, using odds ratios, and Chi-squared tests. Results: differences in the fertility rate among female adolescents across regions and time period were observed, ranging from 40.9 to 72.0 per 1,000 in mothers aged 15-19 years. Adolescents had fewer prenatal care appointments than mothers ≥20 years, and a higher proportion had no partner. Mothers aged 15-19 years were more likely to experience preterm birth (OR:1.1; CI:1.08-1.13; p<0.001, have an infant with low birthweight (OR:1.1; CI:1.10-1.15; p<0.001 and low Apgar score at 5 minutes (OR:1.4; CI:1.34-1.45; p<0.001 than mothers ≥20 years, with the odds for adverse outcomes greater for those aged 10-14 years. Conclusion: this study provides evidence of fertility rates among adolescents remaining higher in regions of social and economic deprivation. Adolescent mothers and their infants more likely to experience adverse perinatal outcomes. Nurses, public health practitioners, health and social care professionals and educators need to work collaboratively to better target strategies for adolescents at greater risk; to help reduce fertility rates and improve outcomes.

Full Text Available INTRODUCTION: Adherence to combination antiretroviral therapy (cART is vital for HIV-infected adolescents for survival and quality of life. However, this age group faces many challenges to remain adherent. We used multiple data sources (role-play, focus group discussions (FGD, and in-depth interviews (IDI to better understand adherence barriers for Rwandan adolescents. Forty-two HIV positive adolescents (ages 12-21 and a selection of their primary caregivers were interviewed. All were perinatally-infected and received (cART for ≥ 12 months. Topics discussed during FGDs and IDIs included learning HIV status, disclosure and stigma, care and treatment issues, cART adherence barriers. RESULTS: Median age was 17 years, 45% female, 45% orphaned, and 48% in boarding schools. We identified three overarching but inter-related themes that appeared to influence adherence. Stigma, perceived and experienced, and inadvertent disclosure of HIV status hampered adolescents from obtaining and taking their drugs, attending clinic visits, carrying their cARTs with them in public. The second major theme was the need for better support, in particular for adolescents with different living situations, (orphanages, foster-care, and boarding schools. Lack of privacy to keep and take medication came out as major barrier for adolescents living in congested households, as well the institutionalization of boarding schools where privacy is almost non-existent. The third important theme was the desire to be 'normal' and not be recognized as an HIV-infected individual, and to have a normal life not perturbed by taking a regimen of medications or being forced to disclose where others would treat them differently. CONCLUSIONS: We propose better management of HIV-infected adolescents integrated into boarding school, orphanages, and foster care; training of school-faculty on how to support students and allow them privacy for taking their medications. To provide better care and
Full Text Available Abstract Background A change in pattern of tobacco use has been observed in the last decade in Norway. Snuff use and occasional smoking have to some degree replaced daily smoking among adolescents and young adults. Daily smoking is known to be negatively associated with social background factors, but little is known about these associations for other types of tobacco use. Our aim was to study different types of tobacco use among adolescents according to gender, educational ambitions, family background factors, and urbanization. Methods Cross-sectional, school-based study with 15 931 participants and response-rate 87%, conducted among 15 and 16 year olds during 2000–2004. Results More girls (33.8% than boys (26.4% were daily or occasional smokers, while more boys (21.4% than girls (3.5% were daily or occasional snuff users. Daily smoking was more common among adolescents planning vocational education, with single parents or poor family economy. Occasional smoking and snuff use (daily or occasionally showed a similar, but less pronounced pattern regarding education and single parent families. Adolescents with parents from foreign countries were less likely to use tobacco. One exception was boys with parents from Muslim majority countries who had an increased risk of daily smoking. A typical combination user of both tobacco types was a Norwegian boy with divorced parents and ambitions to complete vocational studies or only one year of upper secondary school. Conclusion Tobacco use in adolescents is mainly associated with low educational ambitions and less affluent self-reported family economy. Adolescents with divorced parents use more tobacco than those living with both parents. Public health initiatives to avoid or reduce tobacco use should mainly target adolescents in vocational studies and those leaving school early.

Smartphones are prevalently used among adolescents; however, nighttime exposure to blue-enriched light, through electric devices, is known to induce delays of the circadian rhythm phases and poor morning somatic conditions. We therefore investigated whether evening smartphone use may affect sleep-wake cycle and cardiac autonomic nervous system (ANS) activity after awaking in dormitory students. The participants were high school students, living under dormitory rules regarding the curfew, study, meals, lights-out, and wake-up times. The students were forbidden from the use of both television and personal computer in their private rooms, and only the use of a smartphone was permitted. According to prior assessment of smartphone use, we chose age-, sex-, exercise time-matched long (n = 22, >120 min) and short (n = 14, ≤60 min) groups and compared sleep-wake cycle and physiological parameters, such as cardiac ANS activity, blood pressure, and intra-aural temperature. All measurements were performed during 6:30 to 7:00 a.m. in the dormitories. Compared with the short group, the long group showed a significantly lower cardiac ANS activity (2727 ± 308 vs. 4455 ± 667 ms(2), p = 0.030) with a tendency toward a high heart rate, in addition to later bedtimes during weekdays and more delayed wake-up times over the weekend. Blood pressure and intra-aural temperature did not differ between the groups. In this population, evening smartphone use may be associated with altered sleep-wake cycle and a diminished cardiac ANS activity after awakening could be affecting daytime activities.

The aim of this study was to assess urine fluoride concentration, nutritional status, and dental fluorosis in adolescent students living in the rural areas of Guanajuato, Mexico. A cross-sectional study was conducted including participants aged 11-20 years. The presence and severity of dental fluorosis was registered according to the Thylstrup and Fejerskov index (TFI) criteria. Anthropometric measures were also recorded. Urine sample of the first morning spot was recollected to assess urine fluoride concentration by using the potentiometric method with an ion-selective electrode. Water samples were also recollected and analyzed. Bivariate tests were performed to compare urine fluoride concentration according to different variables such as sex, body mass index, and TFI. Nonparametric tests were used. A logistic regression model was performed (SPSS® 21.0). This study included 307 participants with a mean age of 15.6 ± 1.6; 62.5% of the participants showed normal weight. A total of 91.9% of the participants had dental fluorosis, and 61.6% had TFI > 4. Mean fluoride content in urine ranged between 0.5 and 6.65 mg/L, with a mean of 1.27 ± 1.2 mg/L. Underweight children showed greater urine fluoride concentration. The increment of urine fluoride was a related (OR = 1.40) to having severe dental fluorosis. Most of the studied population had moderate or severe dental fluorosis. Urine fluoride concentration was related to fluorosis severity and nutritional status. Underweight children showed greater urine fluoride concentration as well as severe dental fluorosis.

To create a valid tool to measure adolescent resilience, and to determine if this tool correlates with current participation in risk behaviors and prior adverse childhood events. One hundred adolescents were recruited from primary care clinics in New Jersey for this cross-sectional study. A "7Cs tool" was developed to measure resilience using the 7Cs model of resilience. All participants completed the 7Cs tool, the Adverse Childhood Events Survey, and the Health Survey for Adolescents to identify current risk behaviors. Demographic and background data were also collected. To assess the validity of the 7Cs tool, Cronbach alpha, principal factor analysis, Spearman coefficients, and sensitivity analyses were conducted. The χ(2) test and ORs were used to determine if any relationships exist between resilience and prior adverse childhood events and risk taking behaviors. Participants ranged from 13 to 21 years old (65% female). Internal consistency was established using Cronbach alpha (0.7). Lower resilience correlated with higher adverse childhood events (P = .008) and Health Survey for Adolescents scores (P resilience was associated with increased problems in school (OR 2.6; P = .021), drug use (OR 4.0; P = .004), violent behavior (OR 3.7; P = .002), recent depression (OR 5.0; P resilience was associated with participation in exercise (P = .001) and activities (P = .01). The 7Cs tool is an internally validated tool that may be used to screen adolescent resilience and guide pediatricians' counseling against risk behaviors. Further studies will evaluate resilience-building interventions based on results from this study. Copyright © 2017 Elsevier Inc. All rights reserved.

Full Text Available ABSTRACT OBJECTIVE To identify the factors associated with severity of malocclusion in a population of adolescents. METHODS In this cross-sectional population-based study, the sample size (n = 761 was calculated considering a prevalence of malocclusion of 50.0%, with a 95% confidence level and a 5.0% precision level. The study adopted correction for the effect of delineation (deff = 2, and a 20.0% increase to offset losses and refusals. Multistage probability cluster sampling was adopted. Trained and calibrated professionals performed the intraoral examinations and interviews in households. The dependent variable (severity of malocclusion was assessed using the Dental Aesthetic Index (DAI. The independent variables were grouped into five blocks: demographic characteristics, socioeconomic condition, use of dental services, health-related behavior and oral health subjective conditions. The ordinal logistic regression model was used to identify the factors associated with severity of malocclusion. RESULTS We interviewed and examined 736 adolescents (91.5% response rate, 69.9% of whom showed no abnormalities or slight malocclusion. Defined malocclusion was observed in 17.8% of the adolescents, being severe or very severe in 12.6%, with pressing or essential need of orthodontic treatment. The probabilities of greater severity of malocclusion were higher among adolescents who self-reported as black, indigenous, pardo or yellow, with lower per capita income, having harmful oral habits, negative perception of their appearance and perception of social relationship affected by oral health. CONCLUSIONS Severe or very severe malocclusion was more prevalent among socially disadvantaged adolescents, with reported harmful habits and perception of compromised esthetics and social relationships. Given that malocclusion can interfere with the self-esteem of adolescents, it is essential to improve public policy for the inclusion of orthodontic treatment among

Full Text Available BACKGROUND: Chronic pain negatively affects an adolescent’s life; however, little is known about the social impact of chronic pain for adolescents. More is known about the general peer relationships of adolescents with chronic pain than their close friendships. Close friendships begin to take on more importance during adolescence as these relationships facilitate the development of an adolescent’s sense of personal identity and increasing independence from family influences. Thus, chronic pain may create friendship challenges for adolescents beyond those typically experienced during this developmental trajectory, which may negatively impact their abilities to secure social support.

The aim of this study was to compare socioeconomic characteristics of the Roma population living in Roma settlements with the majority population. Moreover, it was aimed to assess socioeconomic differences in health and health-related behaviour within the population living in Roma settlements. Data from the cross-sectional HepaMeta study conducted in Slovakia in 2011 were used. The sample consisted of 452 Roma (mean age = 34.7; 35.2% men) and 403 non-Roma (mean age = 33.5; 45.9% men) respondents. Roma in selected settlements were recruited by local Roma community workers. Respondents from the major population were randomly selected from a list of patients from general practitioners. Data were collected via questionnaire, anthropometric measures and analysed blood samples. Differences in socioeconomic characteristics between the population living in Roma settlements and the majority population were tested using the chi-square test. The contribution of selected socioeconomic characteristics on health and health-related behaviour of the population living in Roma settlements was assessed by logistic regression models adjusted for age and gender. The population living in Roma settlements is characterised by significantly lower socioeconomic standards, and the living conditions are significantly worse compared with the majority. With few exceptions, the study did not confirm any significant association between socioeconomic indicators and health and health-related behaviour within the population living in Roma settlements. The deteriorating effect of living in Roma settlement on health and health-related behaviour seems to be immense regardless differences in socioeconomic characteristics or living condition within the settlement population.

The activity of growing living bacteria was investigated using real-time and in situ rheology -- in stationary and oscillatory shear. Two different strains of the human pathogen Staphylococcus aureus -- strain COL and its isogenic cell wall autolysis mutant -- were considered in this work. For low bacteria density, strain COL forms small clusters, while the mutant, presenting deficient cell separation, forms irregular larger aggregates. In the early stages of growth, when subjected to a stationary shear, the viscosity of both strains increases with the population of cells. As the bacteria reach the exponential phase of growth, the viscosity of the two strains follow different and rich behaviours, with no counterpart in the optical density or in the population's colony forming units measurements. While the viscosity of strain COL keeps increasing during the exponential phase and returns close to its initial value for the late phase of growth, where the population stabilizes, the viscosity of the mutant strain ...
Full Text Available Background and Objectives: Obsessive symptoms among children and adolescent age groups are increasing, an observation made by mental health professionals working with this age group. Our epidemiological study targeted secondary school students to estimate the prevalence of obsessive symptoms, obsessive compulsive disorder and their different obsessive compulsive contents. Methods: The study is cross sectional carried on 1299 secondary school students, the sample size was chosen based on an estimated Obsessive Compulsive Disorder (OCD prevalence of 2% in literature. Equal samples were recruited from the 3 educative zones in Alexandria Governorate. Obsessive compulsive symptoms were assessed by the Arabic version of Lyeton obsessive inventory child version LOI-CV. Students scoring above 35 were subjected to the Mini International Neuropsychiatric Interview for children MINI-KID Arabic. OCD patient students detected by MINI-KID were assessed by psychiatric interview to confirm fulfilling criteria of OCD according to DSM IV-TR criteria. Different obsessive compulsive symptoms were assessed by a standardized questionnaire. Results: Among the studied sample (n = 1299, 201 students scored > 35 on LOI-CV i.e. 15.5% of the total sample have OCS. The prevalence of OCD among studied sample was 2.2% as 29 students from the OCS students were fulfilling diagnostic criteria for OCD according to DSM-IV TR. Common obsessive symptoms were of excessive conscience 65.5%, blasphemous 55.2%, repeated words 51.7% and sexual obsessions 48.2%. Conclusions: The prevalence of obsessive compulsive symptoms is high among adolescent age group. Cultural impact should be considered to better understand obsessive phenomenology, raising the importance of OCD study from a transcultural perspective.

It is estimated that the percentage of students using illicit substances by sixth grade has tripled over the last decade not only in developed countries but in developing countries as well probably due to the transition to a more Western society. Although much has been done to understand the mechanisms underlying substance abuse, few studies have been conducted with minority ethnic and religious groups such as Middle Eastern Youth. The primary goal of this study was to determine whether there are differences in factors contributing to substance abuse in adolescents from Lebanon versus the U.S.A. and to decipher the role of spirituality, religion, and culture among other factors that may influence substance abuse. A correlational cross-sectional design was used with adolescents living in two different countries: Los Angeles, California and Beirut, Lebanon. Muslim adolescents had significantly less rates of alcohol and substance use than Christians in both Lebanon and Los Angeles. More years lived in the U.S.A. increases the likelihood of abuse for both Muslims and Christians. Attachment to God and family was negatively associated with substance abuse. These results among others facilitate a better understanding of the influence of culture, religion, family and personal factors on substance abuse. Culturally sensitive interventions could benefit from the findings of this pilot study.

Objectives. We compared protective factors among bisexual adolescents with those of heterosexual, mostly heterosexual, and gay or lesbian adolescents. Methods. We analyzed 6 school-based surveys in Minnesota and British Columbia. Sexual orientation was measured by gender of sexual partners, attraction, or self-labeling. Protective factors included family connectedness, school connectedness, and religious involvement. General linear models, conducted separately by gender and adjusted for age, tested differences between orientation groups. Results. Bisexual adolescents reported significantly less family and school connectedness than did heterosexual and mostly heterosexual adolescents and higher or similar levels of religious involvement. In surveys that measured orientation by self-labeling or attraction, levels of protective factors were generally higher among bisexual than among gay and lesbian respondents. Adolescents with sexual partners of both genders reported levels of protective factors lower than or similar to those of adolescents with same-gender partners. Conclusions. Bisexual adolescents had lower levels of most protective factors than did heterosexual adolescents, which may help explain their higher prevalence of risky behavior. Social connectedness should be monitored by including questions about protective factors in youth health surveys. PMID:19008523

The prevalence of cardiovascular risk factors is increasing in aboriginal populations in Chile. To study the prevalence of obesity, type 2 diabetes and serum lipids in two aboriginal populations, Mapuche and Aymara, that were transferred from a rural to a urban environment. Two groups of subjects over 20 years were analyzed, Mapuche and Aymara. The Mapuche group was formed by 42 men and 105 women, living in four urban communities of Santiago, and an Aymara group formed by 42 men and 118 women, living in Arica, in Northern Chile. Anthropometric measurements, blood pressure, lipid profile, oral glucose tolerance test, fasting insulin and serum leptin were determined. The prevalence of type 2 diabetes was 6.9% in Aymara and 8.2% in Mapuche subjects. The frequency of glucose intolerance was similar in both groups, but greater among men. A total blood cholesterol over 200 mg/dl was observed in 43.1% of Aymara and 27.9% of Mapuche subjects (p Mapuche individuals, respectively (p= NS). The prevalence of type 2 diabetes and dyslipidemia in turban aboriginal populations is higher than that of their rural counterparts. A possible explanation for these results are changes in lifestyles that come along with urbanization, characterized by a high consumption of saturated fat and refined sugars and a low level of physical activity.

Full Text Available Abstract Background We investigated the association between maternal anthropometric measurements in prepregnancy and at the end of pregnancy and their children's systolic (SBP and diastolic (DBP blood pressure at 11 years of age, in a prospective cohort study. Methods All hospital births which took place in 1993 in the city of Pelotas - Brazil, were identified (5,249 live births. In 2004, the overall proportion of follow-up was 85% and we obtained arterial blood pressure measurements of 4,452 adolescents. Results Independent variables analyzed included maternal prepregnancy weight and body mass index (BMI and maternal weight, and height at the end of pregnancy. Multiple linear regression analysis controlling for the following confounders were carried out: adolescent's skin color, family income at birth, smoking, alcohol intake during pregnancy, and gestational arterial hypertension. Mean SBP and DBP were 101.9 mmHg (SD 12.3 and 63.4 mmHg (SD 9.9, respectively. Maternal prepregnancy weight and BMI, and weight at the end of pregnancy were positively associated with both SBP and DBP in adolescent subjects of both sexes; maternal height was positively associated with SBP only among males. Conclusions Adequate evaluation of maternal anthropometric characteristics during pregnancy may prevent high levels of blood pressure among adolescent children.

Adolescent Maya girls are among the most vulnerable, marginalized sub-populations in Guatemala, a country that is largely young, indigenous and poor. Adolescent Maya girls have limited access to secondary schooling, opportunities to work or earn an income, and sexual and reproductive health information and services. This article explores the extent to which adolescent Maya girls are able to adopt what they have learned in a community-based skills-building and sex education programme in isolated rural, indigenous Guatemalan communities. This is presented through an interview between the authors, who met and worked together in the Population Council's programme Abriendo Oportunidades (Opening Opportunities) for girls aged 8-19 years. The interview discusses what can be done so that indigenous adolescents not only obtain the sexual health information they need, but develop the skills to make decisions, communicate with their peers and parents, and exercise their rights. Much culturally and linguistically sensitive work must be done, using a community-based participatory approach, so that young people who do want to use condoms for protection or contraceptive methods not only have access to the methods, but the support of their families and communities, and government-sponsored sex education programmes, to use them.

Full Text Available Background: Oral conditions are known to affect various aspects of quality of life. Similarly, the social consequence of the quality of life in the day to day living is also equally important. Several studies have quantified the social consequences of diseases through activity limitations in people's daily living. The instruments which cover a broad spectrum of life are proposed to be compared with the clinical oral hygiene status of people from different social classes. Aim: To assess the validity of dental impact on daily living (DIDL questionnaire measuring subjective dental problems and their impact in the day to day life among tribes of Wayanad. Study Design: Cross-sectional. Materials and Methods: DIDL questionnaire developed by Leao and Sheiham was used. We recorded the clinical oral health status using decayed, missing, filled, simplified oral hygiene index, and community periodontal index indices, to correlate the subjective findings of dental impact tribe to obtain construct validity of the questionnaire. Analysis: Descriptive statistics and Spearman's correlation using IBM SPSS software version 20. Results: In the study population of 250 participants, the majority of the participants were from the age group between 36 and 50 years (40% and females were in the majority (64%. The clinical status of the participants was poor in the majority while their perceived impact in their day to day living was found to be relatively satisfied. The study results show the DIDL tool had weak validity in relation to the clinical status with relevance to the social status of Indian tribal population. Conclusion: The study result shows that there was insignificant and weak validity between the DIDL tool and the oral health status among these tribes who were from a low social class. This might be because their priority in life which is different from what a person from high social class. So the dental problem is ignored at the level of individual

To determine the prevalence of dysmenorrhea, its impact, and the treatment-seeking behavior of adolescent Asian girls. A cross-sectional study with 1092 girls from 15 public secondary schools and 3 ethnic groups in the Federal Territory of Kuala Lumpur, Malaysia. Overall, 74.5% of the girls who had reached menarche had dysmenorrhea; 51.7% of these girls reported that it affected their concentration in class; 50.2% that it restricted their social activities; 21.5% that it caused them to miss school; and 12.0% that it caused poor school performance. Ethnicity and form at school were significantly associated with the poor concentration, absenteeism, and restriction of social and recreational activities attributed to dysmenorrhea. Only 12.0% had consulted a physician, and 53.3% did nothing about their conditions. There were ethnic differences in the prevalence, impact, and management of dysmenorrhea. There is a need for culture-specific education regarding menstruation-related conditions in the school curriculum. Copyright 2009 Elsevier Ireland Ltd. All rights reserved.

This study investigated frequencies of smoking, alcohol use, and illicit drug use by diagnostic category in 566 adolescent psychiatric patients, comparing this sample with 8173 adolescents from the general population in Norway who completed the Young-HUNT 3 survey. Frequencies of current alcohol use were high in both samples but were lower among psychiatric patients. Compared with adolescents in the general population, adolescents in the clinical sample had a higher prevalence of current smoking and over four times higher odds of having tried illicit drugs. In the clinical sample, those with mood disorders reported the highest frequencies of smoking, alcohol use, and illicit drug use, whereas those with autism spectrum disorders reported the lowest frequencies. Our results show an increased prevalence of risky health behaviors among adolescents with psychiatric disorders compared with the general population. The awareness of disorder-specific patterns of smoking and substance use may guide preventive measures.

The aim of the current study was to assess the association between sleep duration and sleep patterns and academic performance in 16-19 year-old adolescents using registry-based academic grades. A large population-based study from Norway conducted in 2012, the youth@hordaland-survey, surveyed 7798 adolescents aged 16-19 years (53.5% girls). The survey was linked with objective outcome data on school performance. Self-reported sleep measures provided information on sleep duration, sleep efficiency, sleep deficit and bedtime differences between weekday and weekend. School performance [grade point average (GPA)] was obtained from official administrative registries. Most sleep parameters were associated with increased risk for poor school performance. After adjusting for sociodemographic information, short sleep duration and sleep deficit were the sleep measures with the highest odds of poor GPA (lowest quartile). Weekday bedtime was associated significantly with GPA, with adolescents going to bed between 22:00 and 23:00 hours having the best GPA. Also, delayed sleep schedule during weekends was associated with poor academic performance. The associations were somewhat reduced after additional adjustment for non-attendance at school, but remained significant in the fully adjusted models. In conclusion, the demonstrated relationship between sleep problems and poor academic performance suggests that careful assessment of sleep is warranted when adolescents are underperforming at school. Future studies are needed on the association between impaired sleep in adolescence and later functioning in adulthood.
and mortality in an endemic setting (malaria is regularly found) is concentrated in children below the age of five years, and the increasing resistance to infection and disease with age is conventionally thought to reflect a slow and gradual acquisition of protective immunity. Many recent and comprehensive...... reviews of malarial immunity exist; rather than attempting to add another, this review summarises some of the recent evidence on how protective immunity is acquired in humans and what precipitates clinical disease, specifically as it relates to populations living in areas where the disease is endemic...

to evaluate the quality of health care for children and adolescents living with HIV, among the different types of Primary Health Care services of Santa Maria, Rio Grande do Sul. cross-sectional study, developed with 118 Primary Health Care professionals. The Primary Care Evaluation Instrument, Professional version, was used. For verification of the variables associated with the high score, Poisson Regression was used. the professionals of the Family Health Strategy, when compared to those of the Primary Health Units, obtained a greater degree of orientation to primary care, both for the overall score and for the derived attributes score, as well as for the integrality and community orientation attributes. A specialization in Primary Health Care, other employment and a statutory work contract were associated with quality of care. the Family Health Strategy was shown to provide higher quality health care for children and adolescents living with HIV, however, the coverage is still low. The need was highlighted to expand this coverage and invest in vocational training directed toward Primary Care and making the professionals effective, through public selection procedure, as well as an improvement program that recognizes the care requirements, in these settings, of children and adolescents infected with HIV. avaliar a qualidade de atenção à saúde da criança e adolescente vivendo com HIV, entre os diferentes tipos de serviço de Atenção Primária à Saúde, de Santa Maria, Rio Grande do Sul. estudo transversal, desenvolvido com 118 profissionais da Atenção Primária à Saúde.

The scope of this article is to present and analyze data from Brazilian foster care services for children / adolescents from the perspective of family reintegration. It also seeks to support the implementation of public policies in order to provide effective reintegration in accordance with the differing local contexts. It uses data from 1,157 municipalities that have foster care services. The methodology takes into account the data collection of 2,624 Brazilian centers and 36,929 children and adolescents in care. The growing number of children/adolescents in care is in line with the increase in population size: 8.4 per small city; 60 per large city and 602.4 per metropolis. With respect to care residence in a different municipality there are varying indices: 12.4% in metropolises and 33.6% in small cities, revealing the absence of centers close to family units in the smaller communities. Regarding the activities promoted together with families, it was seen that there are still units that do not perform any activities, which runs contrary to Brazilian law. It is clear that policies for the child/adolescent in foster care centers need to consider the capacity of the municipality in accordance with population size to implement support actions for families to assist in family reintegration.
Full Text Available OBJECTIVE: We provide a population-based overview of health behaviours of children and adolescents with type 1 diabetes in comparison to the general population, and analyse their relevance for glycaemic control and self-rated health status. METHODS: Data from questionnaires of 11- to 17-year-old children and adolescents with diabetes (n = 629 were compared to a representative sample (n = 6,813. RESULTS: Children and adolescents with type 1 diabetes had a significantly increased odds of infrequent physical activity (adjusted OR 1.56, short overall duration of physical activity per week (OR 1.55, difference -1.3 hours/week, and high daily computer use (OR 2.51. They had a lower odds of active and passive smoking (OR 0.31 and OR 0.29, and high daily television time (OR 0.68. The odds of an at least good and excellent self-rated health status was increased with intense physical activity, and decreased with active smoking and prolonged daily use of computer and television. Active smoking and prolonged daily use of computer were associated with higher HbA1c. CONCLUSIONS: Children and adolescents with type 1 diabetes showed a different profile of health behaviour. Their overall health may improve if their education stresses specifically frequent physical activity with longer overall duration and less frequent television or computer use.

To study the independent determinants of graft survival among pediatric and adolescent live donor kidney transplant recipients. Between March 1976 and March 2004, 1600 live donor kidney transplants were carried out in our center. Of them 284 were 20 yr old or younger (mean age 13.1 yr, ranging from 5 to 20 yr). Evaluation of the possible variables that may affect graft survival were carried out using univariate and multivariate analyses. Studied factors included age, gender, relation between donor and recipient, original kidney disease, ABO blood group, pretransplant blood transfusion, human leukocyte antigen (HLA) matching, pretransplant dialysis, height standard deviation score (SDS), pretransplant hypertension, cold ischemia time, number of renal arteries, ureteral anastomosis, time to diuresis, time of transplantation, occurrence of acute tubular necrosis (ATN), primary and secondary immunosuppression, total dose of steroids in the first 3 months, development of acute rejection and post-transplant hypertension. Using univariate analysis, the significant predictors for graft survival were HLA matching, type of primary urinary recontinuity, time to diuresis, ATN, acute rejection and post-transplant hypertension. The multivariate analysis restricted the significance to acute rejection and post-transplant hypertension. The independent determinants of graft survival in live-donor pediatric and adolescent renal transplant recipients are acute rejection and post-transplant hypertension.

Full Text Available Adolescence is a phase of emotionl turmoil and stress. If not balanced with religious practice, it may cause adolescents to fall into moral and social problems such as breach of school discipline, delinquency, drug addiction and sexual permissiveness. Religiosity is one way for adolescents to deal with challenges in life thereby avoiding immoral activities. This is because religiosity may help to balance adolescent emotional, cognitive and social developments.The purpose of this study is to identify the behaviour and level of religiosity among 30 adolescents from single parents families who settle in government-subsidised area of residence, namely known as the Federal Land Development Authority (FELDA. The area is located in the state of Pahang, situated on the eastern part of Malaysia. These adolescents have been selected as research respondents. This research was conducted as a survey using questionnaire as the research instrument. It was constructed based on the guidelines of Islamic Practice Instrument (IPI (Fariza, 2012 and has already been verified in terms of its validity and reliability. The data analysis has adopted the method of descriptive statistics explained in table form. The research results have found that religiosity or religious behaviour that the adolescents most frequently abide by are staying away from gambling, having good thoughts and expectations of Allah, feeling awed and fear of Allah’s power (taqwa, staying away from fornication (zina and supplication (doa to Allah facing the direction of Qibla. The level of religiosity is medium for most adolescents. This factor explains why not many respondents are involved in moral and disciplinary problems at school. This research finds that generally, religiosity protects adolescents from being involved in immoral activities and other vices.
Full Text Available Usually women live longer than men and female centenarians largely outnumber male centenarians. The findings of previous studies identifying a population with a femininity ratio close to 1.0 among centenarians in the mountainous region of Sardinia was the starting point of an in-depth investigation in order to compare mortality trajectories between men and women in that population. The exceptional survival of men compared to women emerges from the comparison with similar Italian data. Age exaggeration for men has been strictly excluded as a result of the age validation procedure. The discussion suggests that besides biological/genetic factors, the behavioral factors including life style, demographic behavior, family support, and community characteristics may play an important role. No single explanation is likely to account for such an exceptional situation and a fully integrated multidisciplinary approach is urgently needed.

What many sincere environmentalists advocate: (severe restrictions on energy use, to reduce global warming), may actually end up being very harmful to the environment. Since 85 percent of the global energy use is derived from carbon based fossil fuels, this may seem to be a reasonable position. However, the proponents of energy use restrictions are ignoring some very important relationships. The greatest damage to the environment, in terms of species loss, is loss and/or human modification of habitat. The two greatest threats to habitat seem to be (1) population pressure and (2) logging. Logging does not necessarily permanently occupy the land, while either default squatter occupation or "colonization by policy" is often permanent. Increased population degrades the land by causing over- farming, and also creates an ever greater demand for raw materials and food resources. Poor people have no time nor money to think about or help save the environment. Therefore the greatest threat to species survival is human population growth and its frequent companion: poverty. There is an existing way to reduce population growth, and thus to reduce pressure on habitats, called "raising the standard of living". Wherever it succeeds, population growth slows rapidly. In many European countries, there would be a negative population growth if not for immigration. Personal energy use is closely correlated with living standards, and it is impossible to have a higher living standard without a higher degree of personal energy use. It would seem, however, that extending high living standards to the developing world would create an even greater demand for the use of fossil fuels. The solution to this dilemma can only be found in the use of very high capacity sources of non- fossil energy that do not significantly damage the environment. Are there sources of clean, economical energy with a large enough combined capacity to provide high living standards for the whole world, including those

Clinical and immunological investigation with immune status evaluation of three groups of adult population of Bryansk Region was performed. The first group included 165 persons living in Vyshkov (settlement of town type in Bryansk Region) contaminated with radionuclides as a result of Chernobyl accident. The second group included 68 persons living in Vyshkov, immunological monitoring of those was performed. The third group consisted of 114 persons living on the "clean" area of Pochep (Bryansk Region). On both areas (contaminated Vyshkov and "clean" Pochep) the large percent of persons (three quarters of all investigated ones) had clinical manifestations of immune deficiency. The immune status of Vyshkov inhabitants was characterized by T-helper/inductor activation. That was expressed in significant increase of CD4+, CD4+/CD8+ in comparison of control group of primary donors and to "clean" Pochep inhabitants and in stable decrease of average values of serum IgG in comparison to control group, IgG and IgM in comparison to Pochep group. Maximum high values of T-helpers under lowest T-suppressor/killer values were observed at clinical symptoms which may be stipulated by radiation factor (loss of hair and teeth, surplus weight, predisposition to bleedings) and in persons working in cattle-breeding.
Full Text Available This paper aims at giving a summary of recent research on the habitat requirements and population structure of beetles and pseudoscorpions living in old, hollow oaks in Sweden. An inventory of old oaks in pasture woodlands revealed that the species richness of beetles is higher at sites that are originally open and are still grazed. The trees in these plots are preferred for two reasons: they are more sun-exposed and have a larger trunk diameter. Many species are harmed by forest regrowth and, thus, to preserve the rarer saproxylic fauna it is important to continue the management of areas with old oaks. In four of thirteen species (Osmoderma eremita, Tenebrio opacus, Elater ferrugineus and Larca lata, the occupancy per tree were found to be significantly positively correlated with the number of trees in the stand. This finding is noteworthy as there is little scientific evidence available to support that saproxylic beetles suffer from habitat fragmentation. The population dynamics were investigated on a certain study species, O. eremita. The results suggest that the individuals of each tree could be seen as a local population, and the populations in all occupied trees in a stand together form a metapopulation.

Full Text Available Abstract Background Adolescents with IBD requiring ostomy surgery experience perioperative needs that may exceed those of patients experiencing other major abdominal surgery 1. This procedure requires ongoing and vigilant daily care and management. Gastrointestinal symptoms and complications impose psychological and social stresses on young patients 2, and the procedure results in body image changes and daily regimens of self-care. This study aimed to explore adolescents' experiences and quality of life following ostomy surgery. Methods Ethnographic interviews and a subsequent focus group were conducted with 20 adolescents with an ostomy or j-pouch being treated at the Hospital for Sick Children in Toronto, Canada. Interviews were transcribed verbatim and subjected to theme generation. Results Findings suggest that adolescents are profoundly affected by their ostomy. Adolescents convey strength as well as adjustment struggles. Identified impacts include body intrusion and body image changes, decreased independence, secrecy about the ostomy, adjustment over time, challenges for the family, and strategies for constructively moving forward. Conclusion Implications address the importance of ensuring meaningful opportunities to understand and reframe the stresses of illness. An ongoing clinical challenge involves the promotion of a healthy self-esteem and psychosocial adjustment for these adolescents and their families. Finding effective ways to minimize stress and embarrassment and reframe personal shame, constitute important clinical priorities. Opportunities for peer support and family dialogue may assist in clarifying worries and easing the burden carried by these young persons. Flexible and adequately funded resources are advocated in fostering quality of life.

Objective. The purpose of this study was to determine the key factors of social well-being of the population in surveillance zone Rivne NPP. Materials and methods. Sociological, hygienic and mathematical methods i.e. comparison of generalized performance characteristics such as relative and average values, expression of interactions between factors using a pairwise correlation (r) were used in the paper. A questionnaire was developed for the public opinion polls with independent blocks of issues: the study of living environment/conditions through the assay of adequacy of ten major areas of life, assessment of satisfaction with the quality of life in household sphere and components and cost items of family budget, satisfaction level of medical care, "Integral Index of Social Well-being" Test (IISW). The sample was representative by age and gender for population of the surveillance zone of Rivne NPP (n=220, 6.7% sampling error). Results. According to opinion polls there is a negative impact on social well-being of low sufficiency in issues of socio-political life, social security and social relations. More than a half of population feels no any socio-economic compensation for the risk of Rivne NPP function in their daily lives. The overall satisfaction index in recreational and cultural sphere is close to the national average value, which may indirectly indicate to a positive impact of subventions to the social infrastructure of surveillance zone. However, satisfaction of population in the required medical care is extremely low, as is the case throughout Ukraine, due to several factors, such as lack of specialists, poor providing with essential medicines, and high cost of medicines. Conclusions. The list of benefits and compensations associated with living near the functioning NPP needs improvement and coordination with opinion of local communities. Their implementation at that needs a permanent information support. Some links are established between areas that are
Full Text Available Abstract Background Anxious parents have many concerns about the future health of their atopic infants. Paediatricians and primary care practitioners need to seek knowledge on long-term outcomes in order to cope with the increasing caseload of suspected allergy and the concerns of parents. The aim of the study was to assess suspected and diagnosed allergy in infancy as predictors of allergy and asthma in adolescence. Methods Families expecting their first baby and making their first visit to a maternity health care clinic in 1986 were selected as the study population in a random sample. There were 1278 eligible study families. The data were provided of the children at the ages of 9 and 18 months and 3, 5, 12, 15 and 18 years by health care professionals, parents, and adolescents (themselves. Results At the age of 9 months, the prevalence of allergy suspicions was distinctly higher than that of allergy diagnoses. At the age of five years suspected allergy approaches were nil, and the prevalence of diagnosed allergy was about 9%. During the adolescence, the prevalence of self-reported allergy increases steadily up to the age of 18 years, and that of asthma remains at approximately 5%. Suspected allergy at the age of 9 or 18 months and at the 5 years of age does not predict allergy at adolescence. Compared with non-allergic children, children with definite allergy at the age of 5 were over 8 times more likely to have allergy and nearly 7 times more likely to have asthma in adolescence. Conclusion An early ascertained diagnosis of allergy, but not suspicions of allergy, predicts prevailing allergy in adolescence. Efforts need to be focused on accurate diagnosis of early childhood allergies.

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.

This study describes and conceptualizes the experiences of stigma in a group of children living with HIV in São Paulo, Brazil, and evaluates the impact of access to highly active antiretroviral therapy (HAART) over the social course of AIDS and over the children's experiences of stigma. Through ethnographic research in São Paulo from 1999 to 2001, the life trajectories of 50 children ages 1-15 living with or affected by HIV were studied. Data were collected via participant observation and semi-structured informal interviews and analyzed using social theories on illness experience and social inequality. Our results demonstrate that AIDS-related stigma occurs within complex discrimination processes that change as children reach adolescence. We found that structural violence in the forms of poverty, racism, and inequalities in social status, gender, and age fuels children's experiences of stigma. We also describe how access to HAART changes the lived experience of children, reduces stigma, and brings new challenges in AIDS care such as adolescents' sexuality and treatment adherence. Based on these results, we propose structural violence as the framework to study stigma and argue that interventions to reduce stigma that solely target the perception and attitudes toward people living with HIV are limited. In contrast universal access to HAART in Brazil is a powerful intervention that reduces stigma, in that it transforms AIDS from a debilitating and fatal disease to a chronic and manageable one, belongs to a broader mechanism to assure citizens' rights, and reduces social inequalities in access to health care.

The scope of this study is to correlate the gingival condition and sociodemographic status of adolescents living in an economically disadvantaged Brazilian region. The survey was conducted with a random sample of 450 adolescents in 13 cities selected in the Jequitinhonha Valley (State of Minas Gerais). The gingival condition was evaluated using a calibrated examiner (Kappa ≥ 0.85). The oral exam was based on the Community Periodontal Index (CPI). The frequencies of individuals were calculated and sextants subsequently assessed using Multiple Correspondence Analysis (ANACOR) to reveal the relationship between CPI and sociodemographic characteristics. The results showed that: 16 (3.6%) were healthy; 235 (52.2%) had gingival bleeding; 36 (8%) had dental calculus and 163 (36.2%) had both bleeding and calculus. ANACOR identified two groups with similarities in relation to periodontal disease. Group one featured 19-year-olds with healthy CPI who work and have higher family income. Group two included 15- and 16-year-olds of both sexes with CPI and gingival bleeding in elementary school with lower family income, who declared themselves to be of mixed or Afro-descendant race. The presence of gingivitis was related to the socioeconomic and demographic characteristics of adolescents in the region.

Despite long-standing interest in the association of psychiatric disorders with intelligence, few population-based studies of psychiatric disorders have assessed intelligence. To investigate the association of fluid intelligence with past-year and lifetime psychiatric disorders, disorder age at onset, and disorder severity in a nationally representative sample of US adolescents. National sample of adolescents ascertained from schools and households from the National Comorbidity Survey Replication-Adolescent Supplement, collected 2001 through 2004. Face-to-face household interviews with adolescents and questionnaires from parents were obtained. The data were analyzed from February to December 2016. DSM-IV mental disorders were assessed with the World Health Organization Composite International Diagnostic Interview, and included a broad range of fear, distress, behavior, substance use, and other disorders. Disorder severity was measured with the Sheehan Disability Scale. Fluid IQ measured with the Kaufman Brief Intelligence Test, normed within the sample by 6-month age groups. The sample included 10 073 adolescents (mean [SD] age, 15.2 [1.50] years; 49.0% female) with valid data on fluid intelligence. Lower mean (SE) IQ was observed among adolescents with past-year bipolar disorder (94.2 [1.69]; P = .004), attention-deficit/hyperactivity disorder (96.3 [0.91]; P = .002), oppositional defiant disorder (97.3 [0.66]; P = .007), conduct disorder (97.1 [0.82]; P = .02), substance use disorders (alcohol abuse, 96.5 [0.67]; P Intelligence was not associated with posttraumatic stress disorder, eating disorders, and anxiety disorders other than specific phobia, and was positively associated with past-year major depression (mean [SE], 100 [0.5]; P = .01). Associations of fluid intelligence with lifetime disorders that had remitted were attenuated compared with past-year disorders, with the exception of separation anxiety disorder. Multiple past
Full Text Available Introduction The frequency of pediatric and adolescent oral and maxillofacial lesions is various in different societies. The present study aimed at investigating the frequency of oral and maxillofacial pediatric and adolescent biopsies in Zahedan (southeast Iran, and compare the results with other epidemiologic studies.Methods and Materials This retrospective study reviewed oral and maxillofacial lesions in patients with 0-18 years old referring to the treatment centers of Zahedan University of Medical Sciences during 12-years period. Patients’ demographic information including age, gender and location of the lesion were collected and statistically analyzed.ResultsIn general, among 1112 oral and maxillofacial lesions, 154 (13.9% cases were related to children and adolescents younger than 18 years old. The average age of patients was 11.4 ± 4.9, 53.2% and 46.8% of them were boys and girls, respectively. The most frequent sites of lesions were the gingiva and lip. The most prevalent lesions included inflammatory/reactive, cystic and neoplastic lesions, respectively. Benign and malignant tumors comprised 12.3% and 4.5% of cases. Moreover, pyogenic granuloma and peripheral giant cell granuloma (PGCG were the most frequent lesions.ConclusionThe most prevalent oral and maxillofacial lesions in patients under 18 years old were inflammatory/reactive lesions in gingiva and in the 13-18 age range. Determining the characteristics of these lesions in the children and adolescents population provides a firm groundwork for proper diagnosis and treatment.

The prevalence and expression of Cluster A personality disorders in adolescence is poorly analyzed and understood. The main goal was to analyze the rate of Cluster A traits and maladaptive personality patterns in adolescents. In addition, the underlying dimensional structure and the possible influence of sex and age in its phenotypic expression were examined. The final sample was comprised of a total of 1,443 participants (M = 15.9 years, SD = 1.2). The instrument used was the Personality Diagnostic Questionnaire-4+ (PDQ-4+). Cluster A maladaptive personality traits are common among adolescents. According to the PDQ-4+, 13.1% (n = 189) of the sample reported a Cluster A maladaptive personality pattern. Analysis of the internal structure yielded two interrelated factors, namely Paranoid and Schizotypal-Schizoid. Males, compared with females, obtained higher scores on the schizotypal subscale when the score was dimensional and on the schizotypal and schizoid subscales when items were dichotomized. These data yield new clues that improve the understanding of Cluster A traits in this sector of the population, and advance in early detection of adolescents at risk of personality disorders.

The Western Australian (WA) 'LiveLighter' (LL) mass media campaign ran during June-August and September-October 2012. The principal campaign ad graphically depicts visceral fat of an overweight individual ('why' change message), whereas supporting ads demonstrate simple changes to increase activity and eat healthier ('how' to change message). Cross-sectional surveys among population samples aged 25-49 were undertaken pre-campaign (N= 2012) and following the two media waves (N= 2005 and N= 2009) in the intervention (WA) and comparison state (Victoria) to estimate the population impact of LL. Campaign awareness was 54% after the first media wave and overweight adults were more likely to recall LL and perceive it as personally relevant. Recall was also higher among parents, but equal between socio-economic groups. The 'why' message about health-harms of overweight rated higher than 'how' messages about lifestyle change, on perceived message effectiveness which is predictive of health-related intention and behaviour change. State-by-time interactions showed population-level increases in self-referent thoughts about the health-harms of overweight (P campaign impact. However, sustained campaign activity will be needed to impact behaviour.

The debilitating and very visible motor effects of the incurable, progressive, and fatal neurodegenerative condition Huntington disease (HD) are accompanied by more insidious cognitive, behavioural and personality disturbance. The usual age of HD onset exposes children and adolescents to the natural history of the condition as it affects a parent. This group of young people has been largely overlooked in most research, which has concentrated upon the experiences of affected individuals and their partners. This study explores the psychosocial context of young people living in families affected by HD, to better understand their experiences and the specific challenges they face. Ten young people from five unrelated families affected by HD separately participated in semi-structured individual interviews. At the time of interview, nine were less than 18 years of age, and none had requested a predictive genetic test. The young people demonstrated a depth of insight in their descriptions of complex and often painful family circumstances. In addition to the tasks and challenges associated with typical adolescent development, young people from families affected by Huntington disease recognize that they face greater responsibilities and stresses. This study highlights areas of unmet needs for young people living in families affected by HD. Best practice HD care should include consideration of the needs of young people in the family, and offer developmentally appropriate HD education, prospective orientation to genetic services, and psychological and social support.

Full Text Available The objective of this article was to identify the possible constructs of one or more apparatus of sexuality and of alliance in adolescents living in poverty in Brazil. The research methodology was a qualitative assessment using an ethnographic approach. The principal data collection technique, in addition to ethnographic observation and documentary analysis, was face-to-face in-depth interviews. Fourteen adolescents living in the same Belém neighbourhood were observed and interviewed, as well as their parents. The data analysis revealed an apparatus of sexuality as an apparatus of safe sex whereas an apparatus of alliance, according to Foucault, was described after analysis and confirmation of the data as an alliance of powerfulness. These results is bringing new light on the question of the social construct of sexuality among adolescents living in poverty, put into better position the use of Foucault’s concepts, considered till now only as philosophical abstractions, and not as empirical results.

The proportion of obese adolescents in Southern Appalachia is among the highest in the nation. Through funding from the National Institute on Minority Health and Health Disparities--National Institutes of Health, the Team Up for Healthy Living project was a cluster-randomized trial targeting obesity prevention in adolescents through a cross-peer intervention. The specific aims of the project were to: 1) develop a peer-based health education program focusing on establishing positive peer norms towards healthy eating and physical activity (PA) among high school students, 2) test program efficacy, and 3) explore mechanisms underlying the program. The study was guided by the Theory of Planned Behavior, which presupposes that human behavior is primarily driven by attitude, subjective norms, perceived behavioral control, and social support. To deliver the intervention, undergraduate students from the disciplines of public health, nutrition, and kinesiology were hired as peer facilitators. Ten area high schools were invited to participate, were matched on demographics and then randomized to intervention or control. The primary outcomes of the study included body mass status, dietary behaviors, PA, and sedentary behaviors which were assessed at baseline and at three and twelve months post baseline. Intervention schools received Team Up for Healthy Living curriculum, which consists of eight 40-minute sessions. The curriculum focused on improving nutrition awareness, PA, leadership and communication. Control schools received their regularly scheduled Lifetime Wellness curriculum. The long-term goal of the study was to establish an effective academia-community partnership program to address adolescent obesity disparity in Southern Appalachia.

Full Text Available Electrophoretic analysis of presumptive twenty gene loci products was conducted in hemolisates and plasma samples of twenty-eight maned wolves (Chrysocyon brachyurus from an area in northeastern São Paulo State, Brazil. The area sampled was divided into three sub-areas, with the Mogi-Guaçu and Pardo rivers regarded as barriers to the gene flow. The polymorphism degree and heterozygosity level (intralocus and average estimated in this study were similar to those detected by other authors for maned wolves and other species of wild free-living canids. The samples of each sub-area and the total sample exhibited genotype frequencies consistent with the genetic equilibrium model. The values of the F-statistics evidenced absence of inbreeding and population subdivision and, consequently, low genetic distances were found among the samples of each area.

Healthcare in Canada has generally not kept pace with the evolving needs of patients since the creation of medicare in the 1960s. Budgets for hospitals, physicians and prescription drugs make up the bulk of spending in health, despite the need for better prevention and management of chronic disease, the needed expansion of home-based care services and the call for reform of front-line primary care. Over the past decade, a number of Canadian health authorities have adopted the US-based Institute for Healthcare Improvement Triple Aim philosophy (better population health, better patient experience and better per capita cost of care) in order to build system-level change. The Atlantic Healthcare Collaboration was one attempt to initiate system-level reform in healthcare delivery for patients living with chronic disease.

From long ago, the Maya civilizations of Mesoamerica have been keenly attuned to the cycles of nature. The Maya have always been careful observers, and more than a thousand years ago, they recorded the motion of the planets, the Sun, and the Moon, and predicted eclipses. These observations were used to create a complex calendar to organize the events of their world. The Maya built great cities containing buildings aligned with the Sun, Moon, and the stars to mark important times of the year. Many astronomical traditions are still practiced today by the Maya of the Yucatán peninsula, Southern states in México, and other areas in Mesoamerica. Traditional farming communities time the cultivation of corn by observing the sky. The living culture of the Mayan people in the Yucatan integrates science and astronomy with every other aspect of their culture. Yucatec Maya, the language spoken by more than 1 million people in the Yucatán today, still carries through oral histories the ancient knowledge of nature. Our hope is that you'll increase your interest and knowledge of the Mayan people and of the enduring wisdom reflected in the daily lives of Mayan families. We present the results of education and public outreach efforts that position astronomy within its cultural context as an effective means of capturing the interest and enabling authentic participation of under-represented populations in science.

Full Text Available This study aimed to monitor diet quality and associated factors in adolescents, adults and older adults from the city of São Paulo, Brazil. We conducted a cross-sectional population-based study involving 2376 individuals surveyed in 2003, and 1662 individuals in 2008 (Health Survey of São Paulo, ISA-Capital. Participants were of both sexes and aged 12 to 19 years old (adolescents, 20 to 59 years old (adults and 60 years old or over (older adults. Food intake was assessed using the 24-h dietary recall method while diet quality was determined by the Brazilian Healthy Eating Index (BHEI-R. The prevalence of descriptive variables for 2003 and 2008 was compared adopting a confidence interval of 95%. The means of total BHEI-R score and its components for 2003 and 2008 were compared for each age group. Associations between the BHEI-R and independent variables were evaluated for each survey year using multiple linear regression analysis. Results showed that the mean BHEI-R increased (54.9 vs. 56.4 points over the five-year period. However, the age group evaluation showed a deterioration in diet quality of adolescents, influenced by a decrease in scores for dark-green and orange vegetables and legumes, total grains, oils and SoFAAS (solid fat, alcohol and added sugar components. In the 2008 survey, adults had a higher BHEI-R score, by 6.1 points on average, compared to adolescents. Compared to older adults, this difference was 10.7 points. The diet quality remains a concern, especially among adolescents, that had the worst results compared to the other age groups.
Full Text Available The urgency of the given research is intimately related to the necessity to choose the comprehension approaches to the evaluation of the children's physical growth, which may be applied in monitoring of the children collectives health status, planning and performance of the preventive and sanitary events at the group and population levels.

Population level data regarding the general mental health status, and the socio-demographic factors associated with the mental health status of adolescents in Australia aged 12-16 years is limited. This study assessed prevalence of mental health problems in a regional population of Australian students in Grades 7-10, and investigated associations between mental health problems and socio-demographic factors. A web-based survey was conducted in 21 secondary schools located in disadvantaged local government areas in one regional local health district of NSW Australia. Mental health problems were measured using the youth self-report Strengths and Difficulties Questionnaire (SDQ) total SDQ score and three subscale scores (internalising problems, externalising problems and prosocial behaviour). Associations between each SDQ outcome and student socio-demographic characteristics (age, gender, Aboriginal and/or Torres Strait Islander Status, remoteness of residential location and socio-economic disadvantage) were investigated. Data are reported for 6793 students aged 12-16 years. Nineteen percent of participants scored in the 'very high' range for the total SDQ, 18.0 % for internalising problems, 11.3 % for externalising problems and 8.9 % for prosocial behaviour problems. Gender and Aboriginal status were associated with all four SDQ outcomes, while age was associated with two, excluding externalising problems and prosocial behaviour. Aboriginal adolescents scored higher for mental health problems than non-Aboriginal adolescents for all four SDQ outcomes. Females scored higher than males for total SDQ and internalising problems, with mean difference greatest at age 15. Males scored higher for externalising problems and lower for prosocial behaviour than females. The finding that mental health problems significantly varied by age, gender and Aboriginality may suggest a need for tailored interventions for groups of adolescents with highest levels of mental health

Full Text Available This study characterized the time-location pattern of 107 residents living in air pollution hotspots, the Waterfront South and Copewood/Davis Streets communities in Camden, NJ. Most residents in the two communities are minority and impoverished individuals. Results showed that employment status played the fundamental role in determining time-location patterns of this study population, and the variations of time-location pattern by season and by day-type were partially attributed to employment status. Compared to the National Human Activity Pattern Survey, the Camden cohort spent significantly more time outdoors (3.8 hours versus 1.8 hours and less time indoors (19.4 hours versus 20.9 hours than the general US population, indicating a higher risk of exposure to ambient air pollution for the Camden cohort. The findings of the study are important for understanding exposure routes and sources for the socioeconomically disadvantaged subgroup and ultimately help develop effective strategies to reduce community exposure to ambient air pollution in “hotspots”.

The alarming problem of a decline in physical activity among children and adolescents and its detrimental effects on public health has been well recognised worldwide. Low physical activity is responsible for 6% of deaths worldwide and 5-10% of deaths in the countries of the WHO European Region, according to country. Within the last decade, many initiatives have been launched to counteract this phenomenon. The objective of presented study was analysis of the level of physical activity among adolescents and young adults in Poland, according to the IPAQ questionnaire. The study group covered 7,716 adolescents: 5,086 children attending high school and secondary schools and 2,630 university students. Low physical activity was noted among 57% of schoolchildren and 20.84% of students. Analysis of the level of physical activity according to the IPAQ indicated that it was lower among girls, compared to boys. An additional analysis, with the consideration of the place of residence, showed that the highest percentage of the population with low physical activity was noted in the rural areas (29.30%), while among the urban inhabitants of cities with a population above 100,000 it was on the level of 23.69% and 20.57%. Median for weekly physical activity by respondents" gender was on the level of 1,554.00 MET*min. weekly among females, and 2,611.00 MET*min. weekly among males (ptowns with a population less than 100,000, whereas among the rural population and inhabitants of large cities with a population of over 100,000 the weekly physical activity was on a similar level (1,830.50 and 1,962.00 respectively). An extended analysis of respondents' physical activity showed that during the day students spend significantly more time in a sedentary position, compared to schoolchildren. The presented results of studies indicate the necessity to continue and intensify actions to promote various forms of physical activity among students and schoolchildren.

The activity of growing living bacteria was investigated using real-time and in situ rheology-in stationary and oscillatory shear. Two different strains of the human pathogen Staphylococcus aureus-strain COL and its isogenic cell wall autolysis mutant, RUSAL9-were considered in this work. For low bacteria density, strain COL forms small clusters, while the mutant, presenting deficient cell separation, forms irregular larger aggregates. In the early stages of growth, when subjected to a stationary shear, the viscosity of the cultures of both strains increases with the population of cells. As the bacteria reach the exponential phase of growth, the viscosity of the cultures of the two strains follows different and rich behaviors, with no counterpart in the optical density or in the population's colony-forming units measurements. While the viscosity of strain COL culture keeps increasing during the exponential phase and returns close to its initial value for the late phase of growth, where the population stabilizes, the viscosity of the mutant strain culture decreases steeply, still in the exponential phase, remains constant for some time, and increases again, reaching a constant plateau at a maximum value for the late phase of growth. These complex viscoelastic behaviors, which were observed to be shear-stress-dependent, are a consequence of two coupled effects: the cell density continuous increase and its changing interacting properties. The viscous and elastic moduli of strain COL culture, obtained with oscillatory shear, exhibit power-law behaviors whose exponents are dependent on the bacteria growth stage. The viscous and elastic moduli of the mutant culture have complex behaviors, emerging from the different relaxation times that are associated with the large molecules of the medium and the self-organized structures of bacteria. Nevertheless, these behaviors reflect the bacteria growth stage.
Full Text Available BACKGROUND: The number of people living with HIV (PLHIV is increasing in the UK. This study estimated the annual population cost of providing HIV services in the UK, 1997-2006 and projected them 2007-2013. METHODS: Annual cost of HIV treatment for PLHIV by stage of HIV infection and type of ART was calculated (UK pounds, 2006 prices. Population costs were derived by multiplying the number of PLHIV by their annual cost for 1997-2006 and projected 2007-2013. RESULTS: Average annual treatment costs across all stages of HIV infection ranged from £17,034 in 1997 to £18,087 in 2006 for PLHIV on mono-therapy and from £27,649 in 1997 to £32,322 in 2006 for those on quadruple-or-more ART. The number of PLHIV using NHS services rose from 16,075 to 52,083 in 2006 and was projected to increase to 78,370 by 2013. Annual population cost rose from £104 million in 1997 to £483 million in 2006, with a projected annual cost between £721 and £758 million by 2013. When including community care costs, costs increased from £164 million in 1997, to £683 million in 2006 and between £1,019 and £1,065 million in 2013. CONCLUSIONS: Increased number of PLHIV using NHS services resulted in rising UK population costs. Population costs are expected to continue to increase, partly due to PLHIV's longer survival on ART and the relative lack of success of HIV preventing programs. Where possible, the cost of HIV treatment and care needs to be reduced without reducing the quality of services, and prevention programs need to become more effective. While high income countries are struggling to meet these increasing costs, middle- and lower-income countries with larger epidemics are likely to find it even more difficult to meet these increasing demands, given that they have fewer resources.

Despite conceptual links between disaster exposure and substance use, few studies have examined prevalence and risk factors for adolescent substance use and abuse in large, population-based samples affected by a recent natural disaster. We addressed this gap using a novel address-based sampling methodology to interview adolescents and parents who were affected by the 4th deadliest tornado outbreak in U.S. Postdisaster interviews were conducted with 2,000 adolescent-parent dyads living within a 5-mile radius of the spring 2011 U.S. tornadoes. In addition to descriptive analyses to estimate prevalence, hierarchical linear and logistic regression analyses were used to examine a range of protective and risk factors for substance use and abuse. Approximately 3% reported substance abuse since the tornado. Greater number of prior traumatic events and older age emerged as consistent risk factors across tobacco and alcohol use and substance abuse since the tornado. Tornado incident characteristics, namely, greater loss of services and resources after the tornado and posttraumatic stress disorder since the tornado, were associated with greater alcohol consumption. Service loss increased risk for binge drinking, whereas, for substance abuse, posttraumatic stress disorder increased risk and parent presence during the tornado decreased risk. Greater family tornado exposure was associated with a greater number of cigarettes smoked in female but not male teen participants. Both trauma and non-trauma-related factors are relevant to postdisaster substance abuse among adolescents. Future research should examine the role of broader ecological systems in heightening or curtailing substance use risk for adolescents following disaster exposure.

There are increasing numbers of mothers as well as fathers who engage in long-term migration to support their children and other family members in their home countries. In this article, the current state of the literature about children and adolescents left at home in these transnational families is surveyed and reviewed. The article reviews the effects on children of the process of separation from parents, the impact of gifts and remittances home, communication with distant parents and the quality of life with their substitute caregivers. The effects of immigration in late childhood or adolescence on these separated children are examined, as well as what is known about the processes of adaptation and family reunification, including migration traumas, impact of gender, and educational outcomes. Suggestions are given for pediatric clinicians working with reunifying families. Gaps in the literature are highlighted and the need for research into factors that promote successful family re-engagement and overall adaptation upon reunification.

Full Text Available Introduction: As the global community makes progress towards the 90-90-90 targets by 2020, a key challenge is ensuring that antiretroviral drugs for children and adolescents are suitable to the context of resource-limited settings. Drug optimization aims to support the expanded use of more simplified, less toxic drug regimens with high barriers to drug resistance that require minimal clinical monitoring while maintaining therapeutic efficacy. This manuscript summarizes the progress made and outlines further critical steps required to ensure that the right drugs are available to start children and adolescents on treatment and to keep them virologically suppressed. Discussion: Building upon previous work in drug optimization, several important steps were taken in 2014 to ensure alignment between WHO dosing recommendations and the requirements of regulatory bodies, to accelerate drug development, to reduce intellectual property barriers to generic production of combined formulations and rationalize drug selection in countries. The priority for the future is to improve access to antiretroviral therapy (ART at the two ends of the paediatric age spectrum – infants and adolescents – where the treatment gap is greatest, and optimize drug sequencing with better use of available medicines for second- and third-line ART. Future efforts in this area will require continuous collaboration and coordination, and the promotion of innovative approaches to accelerate access to new drugs and formulations. Conclusions: While significant progress has been made, additional efforts are needed to ensure that treatment targets are reached by 2020.

The majority of coral reef goby species are short-lived, with some highly abundant species living less than 100 d. To understand the role and consequences of this extreme life history in shaping coral reef fish populations, we quantitatively documented the structure of small reef fish populations over a 26-month period (>14 short-lived fish generations) at an inshore reef on the Great Barrier Reef, Australia. Most species with life spans >1 yr, such as pomacentrids, exhibited a peak in recruitment during the austral summer, driving seasonal changes in the small fish community composition. In contrast, there were no clear changes in goby community composition, despite the abundance of short-lived, high turnover species. Species of Eviota, the most abundant gobiid genus observed, showed remarkably similar demographic profiles year-round, with consistent densities of adults as well as recently recruited juveniles. Our results demonstrate ongoing recruitment of these small cryptic fishes, which appears to compensate for an exceptionally short life span on the reef. Our results suggest that gobiid populations are able to overcome demographic limitations, and by maintaining reproduction, larval survival and recruitment throughout the year, they may avoid population bottlenecks. These findings also underline the potential trophodynamic importance of these small species; because of this constant turnover, Eviota species and other short-lived fishes may be particularly valuable contributors to the flow of energy on coral reefs, underpinning the year-round trophic structure.

Full Text Available ABSTRACT Objective: To evaluate changes in food intake after adolescents attended a food and nutrition education program at a non-profit institution. Methods: Fifty-four adolescents aged 16 to 19 years, of low socioeconomic level, enrolled in an non-governmental organization in São Paulo, underwent a nutritional intervention of six months consisting of six meetings with dieticians, as well as strategic communication and relationship actions. Body weight, height, body mass index, questionnaire on knowledge on nutrition and feeding practices, 24-hour recall, and diet quality assessment using the Diet Quality Index associated with the Digital Food Guide were collected at baseline and after the intervention. Dietary pattern improvement was defined as an increase of at least 5 points in Diet Quality Index associated with the Digital Food Guide. Results: Understanding of food labels increased, and the dietary patterns on weekdays and weekends improved by 33 and 37%, respectively. The intake of legumes, milk, dairy products, fruits, and vegetables increased (adequacy components. However, intakes of nuts and whole grains were low, and intake of moderation components was high. Conclusion: The program improved the dietary patterns of adolescents, making it a viable and inexpensive method to prevent disease and improve health and quality of life. In addition, the Diet Quality Index associated with the Digital Food Guide has proven to be a good nutritional tool for assessing changes in food intake and for guiding future counseling and nutritional intervention actions for this population.
Full Text Available Over the recent years, standardised epidemiological studies of asthma and asthma'like symptoms in the population of children have been conducted. ISAAC (International Study of Asthma and Allergy in Childhood questionnaire has been predominantly used as a tool to assess the prevalence of clinical implications and diagnosed conditions in children. However, this technique has limitations in terms of subject age (children aged 6–7 and 13–14. We have conducted a study on the prevalence of Asthma and allergy in adolescents (children aged 15–17 using the standardised GA2LEN (Global Allergy and Asthma European Network questionnaire in two Russian cities from central region and Siberia (Moscow and Tomsk. It has been found that the prevalence of asthma'like symptoms in adolescents was three times the level of clinically diagnosed asthma, which accounted for no more than 7%, with this indicator having no variance depending on the region of residence.Key words: asthma, GA2LEN, prevalence, epidemiology, adolescents.

Adolescent consumption of sugar-sweetened beverages (SSBs) has increased drastically with detrimental effects such as weight gain, weakened bones, dental caries, and associated higher levels of type II diabetes in this population. While in the clinical setting, rural family nurse practitioner (FNP) students, using Kellogg-funded Smart Phones, screened adolescents aged 13 to 17 years for SSB consumption in the previous 24 hours. Adolescents initially were provided with a pamphlet and related oral teaching concerning SSBs by the FNP students, as well as a water bottle to encourage healthy fluid intake. Screening SSB information was loaded onto Smart Phones, which resulted in immediate access by the primary investigator sometimes even hundreds of miles distant. After 30 days, FNP students completed follow-up phone interviews to reassess SSB consumption in the previous 24 hours. Results concerning decreased SSB consumption were statistically significant. Additionally, Smart Phones were instrumental in high-speed data transfer. Both advantages and disadvantages were encountered when using this evolving technology.

The aim of the present study was to investigate the relationship between eating behaviors and overweight among population-based adolescents in Japan. Study subjects comprised adolescents in the seventh grade (age range, 12-13 years) from Ina, a town in Saitama Prefecture, Japan, between 1999 and 2008. The height and weight of the subjects were measured, and information concerning eating behaviors (eating speed and eating until full) was obtained using a self-administered questionnaire. Among boys (n = 1586), fast eating speed significantly increased the odds ratio (OR) for overweight when compared with medium eating speed, regardless of eating until full or not; moreover, a more marked increase in the OR was observed among boys eating until full (OR: 2.78, 95% confidence interval: 1.76-4.38) than among those not eating until full (2.43, 1.41-4.20). Among girls (n = 1542), fast eating speed led to a significant increase in the OR in those eating until full; however, no significant increases were observed in the OR in those eating quickly and not until full. Among adolescents, fast eating speed was associated with overweight; furthermore, the combination of both fast eating speed and eating until full may have a significant effect on overweight.

The prevalence of the Cluster C traits and personality disorders in adolescents has been poorly analyzed. The main goal of this research was to analyze the rate of the Cluster C traits and maladaptive personality patterns in a community sample of adolescents. We also examined the dimensional structure and the influence of sex and age in its phenotypic expression. The sample comprised a total of 1443 participants (48.2% male) with a mean age of 15.92 years (SD = 1.18). We used the Cluster C subscales of the Personality Diagnostic Questionnaire-4 + (PDQ-4+). The results showed that the traits of personalities "anxious" or "inhibited" are common among adolescents. As the cut-offs PDQ-4+, 28.3% of the sample showed at least one maladaptive personality pattern of Cluster C. The analysis of the internal structure of the items yielded a one-dimensional solution called Inhibited-Anxious personality. We found statistically significant differences by gender in mean scores in the Avoidant subscale and by age in the Dependent subscale. These data yield new clues that improve the understanding of the Cluster C traits and maladaptive patterns of personality in this sector of the population.

This study explored symptoms of social anxiety and multidimensional self-esteem in a clinical, adolescent female eating disorder population. Using self-report measures, data from 344 females revealed significant negative relationships between dimensions of self-esteem and social anxiety. A diagnostic difference emerged, with the restricting subgroup reporting significantly higher perceived physical appearance and global self-worth than those with binge/purge symptoms or bulimia nervosa. No significant age differences or age by diagnosis interaction effects emerged. These findings suggest that in clinical samples of adolescent eating disorders, self-esteem and social anxiety share a significant inverse relationship and seem to remain fairly constant across adolescence.
Full Text Available Abstract Background Many people who have suffered a stroke require rehabilitation to help them resume their previous activities and roles in their own environment, but only some of them receive inpatient or even outpatient rehabilitation services. Partial and unmet rehabilitation needs may ultimately lead to a loss of functional autonomy, which increases utilization of health services, number of hospitalizations and early institutionalization, leading to a significant psychological and financial burden on the patients, their families and the health care system. The aim of this study was to explore partially met and unmet rehabilitation needs of older adults who had suffered a stroke and who live in the community. The emphasis was put on needs that act as obstacles to social participation in terms of personal factors, environmental factors and life habits, from the point of view of four target populations. Methods Using the focus group technique, we met four types of experts living in three geographic areas of the province of Québec (Canada: older people with stroke, caregivers, health professionals and health care managers, for a total of 12 groups and 72 participants. The audio recordings of the meetings were transcribed and NVivo software was used to manage the data. The process of reducing, categorizing and analyzing the data was conducted using themes from the Disability Creation Process model. Results Rehabilitation needs persist for nine capabilities (e.g. related to behaviour or motor activities, nine factors related to the environment (e.g. type of teaching, adaptation and rehabilitation and 11 life habits (e.g. nutrition, interpersonal relationships. The caregivers and health professionals identified more unmet needs and insisted on an individualized rehabilitation. Older people with stroke and the health care managers had a more global view of rehabilitation needs and emphasized the availability of resources. Conclusion Better

Several studies have revealed a high prevalence of risk factors associated with unhealthy lifestyle among individuals with lower socioeconomic status. In Slovakia, one of the most socially and health-disadvantaged groups is the Roma minority. The aim of this study is to explore differences in physical activity, smoking and alcohol consumption between the population living in Roma settlements and the majority population in Slovakia. Data from the cross-sectional epidemiological HepaMeta study conducted in Slovakia in 2011 were used. The sample consisted of 452 Roma (mean age = 34.7; 35.2% men) and 403 non-Roma (mean age = 33.5; 45.9% men) respondents. The differences in health-related behaviour between the population living in Roma settlements and the majority population were analysed using logistic models separately for males and females. These data show a clear difference between the population living in Roma settlements and the majority population with regard to leisure-time physical activity (only in women) and smoking, although not alcohol consumption. The prevalence of leisure-time physical activities such as walking or some other type of sport was significantly lower among Roma women than among non-Roma women. Men and women living in Roma settlements are more likely to smoke on a daily basis and they are heavier smokers in comparison with the majority population. HepaMeta study did not find differences in alcohol consumption between the Roma and non-Roma men. However, Roma women reported less frequent recent drinking and binge-drinking of 6 or more doses of alcohol on a single occasion. The higher prevalence of unhealthy lifestyle activities among Roma seem to contribute to these inequalities in cardiovascular diseases morbidity and mortality in comparison with the majority population.

Seasonal variations of population dynamics of free living nitrogen fixing bacteria, Azospirillum in relation to chemical parameters in Manakkudi mangrove ecosystem was assessed in root and rhizosphere soil samples of mangroves and mangrove associated plants. In rhizosphere soil and root samples, the counts of Azospirillum were recorded maximum in Acrostichum aureum as 8.63 +/- 0.92 x 10(4) and 115.48 +/- 17.36 x 10(4) CFU g(-1), respectively. The counts of Azospirillum in non-rhizosphere soil varied from 0.01 +/- 0.001 x 10(4) to 5.77 +/- 0.92 x 10(4) CFU g(-1) and found maximum in February and minimum in March and September. Azospirillum counts in water samples were found maximum (2.24 x 10(4) CFU l(-1)) in February. During seasonal variations maximum counts of Azospirillum were recorded during southwest monsoon season in Avicennia officinalis (1.40 x 10(4) CFU g(-1)) followed by Rhizophora mucronata (1.07 x 10(4) CFU g(-1)). The average maximum population density of Azospirillum counts was found during non monsoon season (9.73 x 10(4) CFU g(-1)) and the average maximum population density of Azospirillum counts was found with the mangrove associated root samples (13.73 x 10(4) CFU g(-1)). Of the selected isolates Azospirillum lipoferum (60%) was found to be predominant followed by Azospirillum brasilense (25%), Azospirillum irakense (5%), Azospirillum halopraeferens (5%) and Azospirillum amazonense (5%). Of the isolated species, A. halopraeferens exhibited better growth at 35 g l(-1) NaCl. The level of Fe, Cu, Zn and Mn were varied from 0.91 to 15.93 ppm. The level of Mn (12.13 ppm) was found maximum during non-monsoon of rhizosphere soil sample. Highest rainfall (192.80 mm) and atmospheric temperature (25.10 degrees C) were recorded during south west monsoon and non monsoon seasons. The increased population density was greatly influenced by the pH (r = +0.686). The present finding provides enough information on the nitrogen flow through biological process in

There are many factors influencing postoperative health-related quality of life of adolescent idiopathic scoliosis patients, including the degree of the deformity, culture, differences in geography, rural versus urban living environments, and social factors. The objective of this study was to analyze the significance of geographic factors and their differences influencing the postoperative quality of life in females with adolescent idiopathic scoliosis residing in urban and rural environments, by use of the Polish version of the SRS-24 questionnaire. Forty urban and 20 rural postoperative patients with adolescent scoliosis with a minimum 2-year follow-up period after surgery were included in the study. The process of cross-cultural adaptation was performed according to the IQOLA Project. General results of the Polish SRS-24 equalled 4.1 (SD 0.5) and 4.0 (SD.0.5) in the rural and urban groups of patients, respectively. The 2 groups do not differ in incidence of floor and ceiling effects. The Cronbach's alpha values are excellent for the general result of SRS-24 in urban and rural groups (0.85 and 0.85, respectively). The sub-groups differed significantly in the self-image after surgery domain (p=0.048). Patients from the rural group scored higher in the self-image after surgery domain but reported higher pain levels when compared to urban patients. The associations between SRS-24 results and radiographic parameters in the rural group of patients were strong, compared with moderate relations reported in the urban group.

Depression and obesity/overweight during pregnancy are important public health concerns, as they are frequently associated with poor birth outcomes. The Living Smart, Living Fit® (LSLF) program was an intervention program initiated in 2008 to provide comprehensive care to low-income pregnant and postpartum women with elevated body mass index (BMI) and depressive symptoms. It linked patients to clinical care coordinators trained in motivational interviewing who promoted participation in a portfolio of mental and physical wellness activities. The objective of this study was to evaluate the effectiveness of LSLF in improving depression, BMI, birth weight, and smoking status among low-income perinatal patients. Women with Patient Health Questionnaire (PHQ-9) depression scores ≥10 and/or BMI >25 kg/m(2) at their prenatal intake visit were eligible for enrollment into the LSLF program. Enrolled participants met with clinical care coordinators who encouraged engagement in a portfolio of LSLF activities that included pregnancy/family, physical health, and mental health interventions. Outcomes were measured at the 6-week postpartum visit and included change in PHQ-9 scores, change in BMI, birth weight, and change in smoking status. Of the 107 enrollees, 86% participated in some LSLF activity. Participation in pregnancy/family related activities was significantly associated with decreased PHQ-9 scores. Participation in mental health services was significantly associated with increased birth weight. No changes in BMI or smoking status were associated with LSLF involvement. The findings of this pilot study indicate that pregnant women with depression or obesity/overweight can benefit from care coordination and a portfolio of activities for mental and physical wellness. The LSLF program provides a model for delivering this patient-centered comprehensive support. Further research should include more controlled trials to better evaluate the effectiveness of LSLF intervention.
Full Text Available Abstract Background Different types of devices are available and the choice about which to use depends on various factors: cost, physical characteristics, performance, and the validity and intra- and interinstrument reliability. Given the large number of studies that have used uniaxial or triaxial devices, it is of interest to know whether the different devices give similar information about PA levels and patterns. The aim of this study was to compare physical activity (PA levels and patterns obtained simultaneously by triaxial accelerometry and uniaxial accelerometry in adolescents in free-living conditions. Methods Sixty-two participants, aged 13-16 years, were recruited in this ancillary study, which is a part of the Healthy Lifestyle in Europe by Nutrition in Adolescence (HELENA. All participants wore a uniaxial accelerometer (ActiGraph GT1M®, Pensacola, FL and a triaxial accelerometer (RT3®, Stayhealthy, Monrovia, CA simultaneously for 7 days. The patterns were calculated by converting accelerometer data output as a percentage of time spent at sedentary, light, moderate, and vigorous PA per day. Analysis of output data from the two accelerometers were assessed by two different tests: Equivalence Test and Bland & Altman method. Results The concordance correlation coefficient between the data from the triaxial accelerometer and uniaxial accelerometer at each intensity level was superior to 0.95. The ANOVA test showed a significant difference for the first three lower intensities while no significant difference was found for vigorous intensity. The difference between data obtained with the triaxial accelerometer and the uniaxial monitor never exceeded 2.1% and decreased as PA level increased. The Bland & Altman method showed good agreement between data obtained between the both accelerometers (p Conclusions Uniaxial and triaxial accelerometers do not differ in their measurement of PA in population studies, and either could be used in such

The objective of this study was to evaluate the impact of malocclusion on the quality of life (QOL) of adolescents in Brazil. We carried out a cross-sectional study in a sample population of 1015 schoolchildren aged 12 to 15 years from São Luís, Maranhão, Brazil. The explanatory variable was malocclusion, evaluated on the basis of the normative need or the adolescent's self-perceived need for dental treatment. Normative need for dental treatment was determined by professional diagnosis, made on the basis of Angle's classification, the Dental Aesthetic Index, and other morphological deviations (e.g., posterior crossbite, posterior open bite, and deep overbite). We analyzed the impact of malocclusion on the QOL using the Portuguese version of the Oral Health Impact Profile-14. Associations were estimated by using the prevalence ratio (PR) in Poisson regression analysis, with hierarchized modeling. An alpha of 5% was adopted as the criterion for statistical significance. The QOL of adolescents was impacted by malocclusion, classified by a normative need for treatment according to the Dental Aesthetic Index (PR = 1.27; 95% confidence interval [CI] = 1.03-1.56) or by the self-perceived need for treatment (PR = 2.54; 95% CI = 1.81-3.56). Certain sociodemographic variables, including the head of the family (PR = 1.52; 95% CI = 1.02-2.23), greater educational level of the head of the family (PR = 0.32; 95% CI = 0.17-0.61), and female sex (PR = 1.40; 95% CI = 1.05-1.89), had negative associations with QOL. We conclude that malocclusion has a negative impact on the QOL of adolescents, associated with socioeconomic conditions and the cosmetic effects of malocclusion.

Limited evidence exists concerning the importance of social contexts in adolescent substance use prevention. In addition to the important role schools play in educating young people, they are important ecological platforms for adolescent health, development and behaviors. In this light, school community contexts represent an important, but largely neglected, area of research in adolescent substance use and prevention, particularly with regard to peer influences. This study sought to add to a growing body of literature into peer contexts by testing a model of peer substance use simultaneously on individual and school community levels while taking account of several well established individual level factors. We analyzed population-based data from the 2009 Youth in Iceland school survey, with 7,084 participants (response rate of 83.5%) nested within 140 schools across Iceland. Multilevel logistic regression models were used to analyze the data. School-level peer smoking and drunkenness were positively related to adolescent daily smoking and lifetime drunkenness after taking account of individual level peer smoking and drunkenness. These relationships held true for all respondents, irrespective of socio-economic status and other background variables, time spent with parents, academic performance, self-assessed peer respect for smoking and alcohol use, or if they have substance-using friends or not. On the other hand, the same relationships were not found with regard to individual and peer cannabis use. The school-level findings in this study represent context effects that are over and above individual-level associations. This holds although we accounted for a large number of individual level variables that studies generally have not included. For the purpose of prevention, school communities should be targeted as a whole in substance use prevention programs in addition to reaching to individuals of particular concern.
Editors' Summary Background Throughout most of human history, people have lived in tight-knit communities where there was likely to be someone to turn to for help, advice, or company. But the modern way of life in industrialized countries is greatly reducing the quantity and quality of social relationships. Instead of living in extended families, many people now live miles away from their relatives, often living and working alone. Others commute long distances to work, which leaves little tim...

Full Text Available Low birthweight (LBW is associated with increased mortality in infancy, but its association with mortality in later childhood and adolescence is less clear. We investigated the association between birthweight and all-cause mortality and identified major causes of mortality for different birthweight groups.We conducted a population study of all live births occurring in England and Wales between 1 January 1993 and 31 December 2011. Following exclusions, the 12,355,251 live births were classified by birthweight: 500-1,499 g (very LBW [VLBW], n = 139,608, 1,500-2,499 g (LBW, n = 759,283, 2,500-3,499 g (n = 6,511,411, and ≥3,500 g (n = 4,944,949. The association of birthweight group with mortality in infancy (<1 y of age and childhood/adolescence (1-18 y of age was quantified, with and without covariates, through hazard ratios using Cox regression. International Classification of Diseases codes identified causes of death. In all, 74,890 (0.61% individuals died between birth and 18 y of age, with 23% of deaths occurring after infancy. Adjusted hazard ratios for infant deaths were 145 (95% CI 141, 149 and 9.8 (95% CI 9.5, 10.1 for the VLBW and LBW groups, respectively, compared to the ≥3,500 g group. The respective hazard ratios for death occurring at age 1-18 y were 6.6 (95% CI 6.1, 7.1 and 2.9 (95% CI 2.8, 3.1. Male gender, the youngest and oldest maternal age bands, multiple births, and deprivation (Index of Multiple Deprivation score also contributed to increased deaths in the VLBW and LBW groups in both age ranges. In infancy, perinatal factors, particularly respiratory issues and infections, explained 84% and 31% of deaths in the VLBW and LBW groups, respectively; congenital malformations explained 36% and 23% in the LBW group and ≥2,500 g groups (2,500-3,499 g and ≥3,500 g groups combined, respectively. Central nervous system conditions explained 20% of deaths in childhood/adolescence in the VLBW group, with deaths from neoplasms and

From January 1993 to June 1996, the epidemiology of myxomatosis and viral haemorrhagic disease (VHD) was studied in a free-living population of wild rabbits (Oryctolagus cuniculus) in Spain by means of serological surveys and radiotracking. Myxomatosis was endemic and associated with the breeding period. Its serological pattern was characterised by a 100 per cent prevalence of antibodies in adult rabbits and a rapid increase in antibodies in young rabbits in their first year. No mortality from myxomatosis was detected in adults, and mortality in young rabbits could not be estimated because of interference by predators and scavengers and the deaths of many radiotagged rabbits inside their burrows. VHD was also an endemic disease associated with the breeding period. Adults had a higher prevalence of antibodies against VHD than young rabbits, reaching values of 80 to 90 per cent. During the study, there was an increase in rabbit numbers as a result of a decrease in mortality from predation which was associated with an increase in mortality due to VHD and in the prevalence of antibodies to VHD. Mortality from VHD was lower in rabbits with VHD antibodies than in seronegative rabbits, but some mortality from the disease was also detected in seropositive rabbits. The annual mean mortality rate due to VHD in adult rabbits was estimated to be 21.8 per cent.

A long-standing belief in the literature on sex offenders is that sexually victimized youths are at increased risk of becoming sex offenders themselves. The present study tested the link between past sexual abuse, either with or without contact, and sexually offending behavior in a representative sample of male and female adolescents while controlling for other types of abuse, mental health problems, substance use, and non-sexual violent behaviors. Self-reported data were collected from a nationally representative sample of 6,628 students attending 9th grade public school in Switzerland (3,434 males, 3,194 females, mean age = 15.50 years, SD = 0.66 years). Exposure to contact and non-contact types of sexual abuse was assessed using the Child Sexual Abuse Questionnaire and sexually offending behavior by the presence of any of three behaviors indicating sexual coercion. Two-hundred-forty-five males (7.1 %) and 40 females (1.2 %) reported having sexually coerced another person. After controlling for non-sexual abuse, low parent education, urban versus rural living, mental health problems, substance use, and non-sexual violent behavior, male adolescents who were victims of contact sexual abuse and non-contact sexual abuse were significantly more likely to report coercive sexual behaviors. Females who experienced contact or non-contact sexual abuse were also found at increased risk of committing sexual coercion after controlling for covariates. The present findings demonstrate a strong relationship between past sexual abuse, with and without physical contact, and sexual-offending behavior in male and female adolescents. Reducing exposure to non-contact sexual abuse (like Internet-based sexual exploitation) should become a new area of sexual violence prevention in youths.

The purpose of this article is to share current knowledge about adolescent self-mutilation (SM), and to discuss treatment approaches for affected teens and young adults. One in eight American teenagers experiences depression or anxiety. The growing phenomenon of SM is a particularly worrisome coping mechanism used by teens and young adults to deal with stress and sadness. The incidence of SM is increasing, and might be fueled by current trends in music and media that highlight violent and self-injurious behaviors. SM represents a "cry for help" by adolescents who are suffering. Self-mutilators who repeatedly cut themselves with razors, scissors, knives, or sharp glass are not attempting suicide, but are seeking to relieve extreme anxiety, tension, or pain. Medical literature regarding SM is limited, and evidence-based treatment approaches have not been documented; however, early discovery of SM and the development of a multifaceted treatment approach that incorporates the child, family, and trusted practitioners could be instrumental in managing SM. There is hope that antidepressant medications may also be beneficial. Research is needed to identify successful treatment approaches, and to discover the best ways to educate teens, families, educators, and community leaders about the prevalence of SM in our youth.

The study of the features reactions of the animals a differing complicated individual development (metamorphosis) and living in conditions of radioactive contamination is an important trend in the modern radio-ecology. This information is of interest not only from the point of view of detection the mechanisms of radiobiological effects (hyper-radiosensitivity, hormesis, radio-adaptation, etc.) but also viewpoint of predicting delayed radiation effects that is necessary at account the normalization of technogeneous loading on natural ecosystems. An assessment of the level of cytogenetic damages (single-strand and double-strand DNA breaks) in the blood cells of tadpoles of Rana arvalis living in areas contaminated of wastes radium production (Russia, Komi Republic, Ukhta district) was conducted. Using this biological matter as a bioindicator due to the fact that development amphibian is carried out by metamorphosis and includes larval stage. At this stage post-embryonic development of an individual are the most sensitive to anthropogenic impact. To exclude the effects of other factors (temperature, age-specific peculiarities, overpopulation, etc.) on the formation of DNA damages from the studied reservoirs were taken laying eggs of amphibians (12-15 egg laying from the area) which afterwards are contain in strictly controlled laboratory conditions using water, belt silt, plants of native pond. The reaction of amphibians on the contamination was assessed by the level of DNA damage by method Comet assay was determined. With each egg laying were selected for 7 even-aged individuals. Total for cytogenetic analysis was used 189 individuals. It is shown that in animals that develop on the radio-contaminated area the level of single-strand DNA (alkaline pH version of the Comet assay) was higher than in the control area. According an estimate to the level of double-strand DNA (neutral pH version of the Comet assay) significant differences not was found. The high variability

Full Text Available Background: Since the beginnings of the Infection with HIV, mankind has been greatly concerned. This disease emerged with a series of stigmata, injuring personal integrity of those who suffer from it. Methods: A descriptive study made in Cienfuegos, in which 120 adolescents and 29 PVHIV were inquired and also conferences about this illness were given. Results and Conclusions: The 120 inquired affirmed they knew about the disease and was receiving information regarding it. The majority identifies blood, vaginal secretions, semen, sharing contaminated needles and syringes as main ways of transmission, they also consider that keeping a stable mate friend is the best way to protect themselves. The 50,8% think the names of the infected should be informed to population, and the 15,% is worried about sharing their working or scholar life with them. The 26% think the infected people should live isolated in a sanatorium. On the other hand, 16 PVHIV said they have felt sometimes discriminated, and 11 stated that at the time of asking for medical help, the personnel have attended them in a despicable manner. 3 of them felt the familiar rejection, and 7 stated that the community and his very friends were getting away from them.

At the epicentre of the HIV epidemic in southern Africa, adolescent girls and young women aged 15-24 contribute a disproportionate ~30% of all new infections and seroconvert 5-7 years earlier than their male peers. This age-sex disparity in HIV acquisition continues to sustain unprecedentedly high incidence rates, and preventing HIV infection in this age group is a pre-requisite for achieving an AIDS-free generation and attaining epidemic control. Adolescent girls and young women in southern Africa are uniquely vulnerable to HIV and have up to eight times more infection than their male peers. While the cause of this vulnerability has not been fully elucidated, it is compounded by structural, social and biological factors. These factors include but are not limited to: engagement in age-disparate and/or transactional relationships, few years of schooling, experience of food insecurity, experience of gender-based violence, increased genital inflammation, and amplification of effects of transmission co-factors. Despite the large and immediate HIV prevention need of adolescent girls and young women, there is a dearth of evidence-based interventions to reduce their risk. The exclusion of adolescents in biomedical research is a huge barrier. School and community-based education programmes are commonplace in many settings, yet few have been evaluated and none have demonstrated efficacy in preventing HIV infection. Promising data are emerging on prophylactic use of anti-retrovirals and conditional cash transfers for HIV prevention in these populations. There is an urgent need to meet the HIV prevention needs of adolescent girls and young women, particularly those who are unable to negotiate monogamy, condom use and/or male circumcision. Concerted efforts to expand the prevention options available to these young women in terms of the development of novel HIV-specific biomedical, structural and behavioural interventions are urgently needed for epidemic control.

From 1949-1962, regions of Kazakstan near the Semipalatinsk Nuclear Test Site (SNTS) were contaminated with high levels of radioactive fallout from atomic bomb tests carried out at the SNTS. The effective-dose is a principal criterion for the evaluation of the effect of radioactive fallout upon population. Thyroid disease prevalence may be ascertained, as a biomarker of radiation exposure and because it is of interest in itself. Some features from three studies of thyroid gland status among population living around SNTS will be reported. The first study is a case review of pathological findings of 7,271 patients from three regions adjacent to the SNTS, who were surgically treated during 1966-96; the second is a thyroid screening study of a cohort of 3000 village residents who were <20 years of age at the time of major fallout events in the Semipalatinsk region; the third is a complex molecular, morphological investigation and some approaches to rehabilitation of patients with thyroid abnormalities. Our first study revealed that there is a significant trend for the proportion of thyroid cancer to increase over time in the Semipalatinsk region of Kazakstan 20-29 years after onset of testing in 1949, which might be related to radiation exposure. There are many ethnic groups in this region. Our research among two main ethnic groups (native Kazakh and European extraction) detected that the initial level of thyroid abnormalities and thyroid cancer was higher among residents of European extraction. The total number of surgical cases increased among both ethnic groups over the years, but the numbers of cases with Hashimoto's thyroiditis and thyroid cancer increased dramatically among ethnic Kazakhs. Overall, papillary and follicular cancers predominated, but it should be noted the relatively high percentage of follicular cancers after 1982 in the Semipalatinsk region. The primary screening outcome measure was the prevaleance of thyroid nodules as determined by

This study examined, within the context of the Contingencies of Self-Worth model, state-based associations between self-esteem and body satisfaction using the experience sampling method. One hundred and forty-four adolescent girls (mean age = 14.28 years) completed up to 6 assessments per day for one week using Palm Digital Assistants, in addition to baseline measures of trait body satisfaction and self-esteem. Results showed considerable variation in both state-based constructs within days, and evidence of effects of body satisfaction on self-esteem, but not vice versa. Although these state-based associations were small in size and weakened as the time lag between assessments increased for the sample as a whole, individual differences in the magnitude of these effects were observed and predicted by trait self-esteem and body satisfaction. Collectively, these findings offer support for key tenets of the Contingencies of Self-Worth model.

Background The UK sports drinks market has a turnover in excess of £200 million. Adolescents consume 15.6% of total energy as free sugars, much higher than the recommended 5%. Sugar sweetened beverages, including sports drinks, account for 30% of total free sugar intake for those aged 11-18 years.Objective To investigate children's knowledge and attitudes surrounding sports drinks.Method One hundred and eighty-three self-complete questionnaires were distributed to four schools in South Wales. Children aged 12-14 were recruited to take part. Questions focussed on knowledge of who sports drinks are aimed at; the role of sports drinks in physical activity; and the possible detrimental effects to oral health. Recognition of brand logo and sports ambassadors and the relationship of knowledge to respondents' consumption of sports drinks were assessed.Results There was an 87% (160) response rate and 89.4% (143) claimed to drink sports drinks. 45.9% thought that sports drinks were aimed at everyone; approximately a third (50) viewed teenagers as the target group. Over two thirds recognised the brand logos, yet less than a third could identify brand ambassadors. About half were aware that dental erosion may result from consumption and approximately two thirds knew that they were linked to dental caries and energy provision. Despite this the majority claimed to drink them. As previously reported most of those drinking sports drinks did so because of the taste.Conclusion Whilst most of the respondents had some understanding of the detrimental effects on health the majority of them were drinking them regularly despite this knowledge. Work is therefore needed at a macro level, with soft drink manufacturers, to consider marketing and reformulation of products for adolescent consumers who appear to enjoy them.

analyze trends in fertility rates and associations with perinatal outcomes for adolescents in Santa Catarina, Brazil. a population-based study covering 2006 to 2013 was carried out to evaluate associations between perinatal outcomes and age groups, using odds ratios, and Chi-squared tests. differences in the fertility rate among female adolescents across regions and time period were observed, ranging from 40.9 to 72.0 per 1,000 in mothers aged 15-19 years. Adolescents had fewer prenatal care appointments than mothers ≥20 years, and a higher proportion had no partner. Mothers aged 15-19 years were more likely to experience preterm birth (OR:1.1; CI:1.08-1.13; pprematuros (OR:1,1; IC:1,08-1,13; pprematuro (OR:1,1; IC:1,08-1,13; p<0,001), bebé con peso bajo al nacer (OR:1,1; IC:1,10-1,15; p<0,001) y puntuación de Apgar baja a los 5 minutes (OR:1,4; IC:1,34-1,45; p<0,001) fue superior para madres entre 15 y 19 años en comparación con madres ≥20 años, con mayores chances de resultados negativos para aquellas entre 10 y 14 años de edad. este estudio evidencia que las tasas de fertilidad entre las adolescentes siguen superiores en regiones de pobreza social y económica. Madres adolescentes y sus bebés tienen mayor probabilidad de efectos perinatales adversos. Enfermeros, trabajadores de salud pública, profesionales de salud y asistencia social y educadores deben colaborar para mejor dirigir estrategias a adolescentes con riesgo superior; para fines de ayudar a reducir las tasas de fertilidad y mejorar los resultados.

Long-lived plant species are highly valued environmentally, economically, and socially, but can also cause substantial harm as invaders. Realistic demographic predictions can guide management decisions, and are particularly valuable for long-lived species where population response times can be long. Long-lived species are also challenging, given population dynamics can be affected by factors as diverse as herbivory, climate, and dispersal. We developed a matrix model to evaluate the effects of herbivory by a leaf-feeding biological control agent released in Australia against a long-lived invasive shrub (mesquite, Leguminoseae: Prosopis spp.). The stage-structured, density-dependent model used an annual time step and 10 climatically diverse years of field data. Mesquite population demography is sensitive to source-sink dynamics as most seeds are consumed and redistributed spatially by livestock. In addition, individual mesquite plants, because they are long lived, experience natural climate variation that cycles over decadal scales, as well as anthropogenic climate change. The model therefore explicitly considered the effects of both net dispersal and climate variation. Herbivory strongly regulated mesquite populations through reduced growth and fertility, but additional mortality of older plants will be required to reach management goals within a reasonable time frame. Growth and survival of seeds and seedlings were correlated with daily soil moisture. As a result, population dynamics were sensitive to rainfall scenario, but population response times were typically slow (20-800 years to reach equilibrium or extinction) due to adult longevity. Equilibrium population densities were expected to remain 5% higher, and be more dynamic, if historical multi-decadal climate patterns persist, the effect being dampened by herbivory suppressing seed production irrespective of preceding rainfall. Dense infestations were unlikely to form under a drier climate, and required net

In the context of sustainable reconstruction of Haiti following the earthquake of January 12, 2010, this research analyses the processes of resilience and creators of young and adolescent Haitians. In particular, it examines the role of family, school, care institutions, beliefs, association networks, the state and the international community in the development of these processes. These strata are considered as human resources that may assist in the living of difficult experiences, and reconstruction-shoring research mainly aims to identify guardians' resilience among young and adolescent Haitians living in camps in Port-au-Prince and the other most affected cities after the nearby earthquake. From a questionnaire developed jointly with the University Lumière Lyon 2 (CRPPC) Editec and the State University of Haiti (UEH) in the context of research, individual interviews were conducted with a sample of n=1475 children and adolescents, 782 girls and 693 boys, 19% of whom were under the age of 6 years, 52% aged 6 to 15 years and 29% aged 15 to 20 years. This allowed the collection of their perception and representation of different elements, which serve as scaffolding to cope with the post-traumatic situation they experienced and to analyse and establish the correlation links between the tutors identified. Among the young people in the sample, 97% are mostly educated, and they remain in three cities that have been particularly affected by the earthquake: the capital Port-au-Prince, Leogane a commune of Port-au-Prince located in the department of the West, and Jacmel a commune of Haiti and head of the department of the South East. We enjoyed the perception and representation of children and adolescents on several potential guardians' resilience: family, school, health care institutions, places of worship, social and community networks, government and international organizations. Some data concluded that tutors can actually be correlated and identified by sex and level
Full Text Available People’s thoughts often focus on the suicide victim immediately after a completed suicide. Yet, the real victims of such an event are those individuals who are left behind to cope with the aftermath of the suicide. This phenomenological psychological study explored the lived experiences of late-adolescent suicide survivors, particularly those negative experiences that seemed to worsen in the weeks and months after a significant other’s completed suicide. The research participants were five female late-adolescents (aged 17–22 years who were recruited by means of purposive sampling at a South African tertiary institution and at youth camps. Data collection consisted of collage-facilitated, face-to-face phenomenological interviews. In addition, some participants provided documentary material in the form of personal diaries, letters and poems. The data analysis was conducted according to Giorgi’s phenomenological method. The following salient experiences emerged during the data analysis: guilt, self-blame, blaming others or God, anger, loss or restriction of ‘self’, depression, suboptimal behavioural coping patterns, changes in relationship dynamics, and suicidality. The results of this study can be used by mental health professionals and caregivers to support adolescent suicide survivors effectively, in the midst of their mourning.

Full Text Available Background. Despite the frequency of traumatic or stressful events experienced by refugee children and adolescents prior to migration and following resettlement, the majority do not experience mental health problems emphasising the critical nature of resilience. While a host of factors deemed to be protective of mental health in young refugees have been identified, there has been little research exploring the role of resilience as a distinct psychological construct. This study aimed to explore the nature of psychological resilience in refugee adolescents and the relationship between resilience and depression, other emotional and behavioural problems, and mental health service uptake. Method. One hundred and seventy multiethnic refugee adolescents aged 13–17 from South Australia were administered a survey comprising the Connor-Davidson Resilience Scale (CD-RISC, Children’s Depression Inventory (CDI, and Strengths and Difficulties Questionnaire (SDQ. Results. Females tended to have higher resilience, as did those adolescents who had been living in Australia longer. Adolescents suffering from depressive symptoms or other emotional or behavioural problems had lower resilience. There was little evidence of an association between resilience scores and exposure to trauma or service utilisation. Discussion. Fostering resilience may be critical to efforts to prevent or reduce mental health problems in refugee adolescents.

Ballet dancing is a multifaceted activity requiring muscular power, strength, endurance, flexibility, and agility; necessitating demanding training schedules. Furthermore dancers may be under aesthetic pressure to maintain a lean physique, and adolescent dancers require extra nutrients for growth and development. This cross-sectional study investigated the nutritional status of 47 female adolescent ballet dancers (13-18 years) living in Auckland, New Zealand. Participants who danced at least 1 hr per day 5 days per week completed a 4-day estimated food record, anthropometric measurements (Dual-energy X-ray Absorptiometry) and hematological analysis (iron and vitamin D). Mean BMI was 19.7 ± 2.4 kg/m2 and percentage body fat, 23.5 ± 4.1%. The majority (89.4%) of dancers had a healthy weight (5th-85th percentile) using BMI-for-age growth charts. Food records showed a mean energy intake of 8097.3 ± 2155.6 kJ/day (48.9% carbohydrate, 16.9% protein, 33.8% fat, 14.0% saturated fat). Mean carbohydrate and protein intakes were 4.8 ± 1.4 and 1.6 ± 0.5 g/kg/day respectively. Over half (54.8%) of dancers consumed less than 5 g carbohydrate/kg/day, and 10 (23.8%) less than 1.2 g protein/kg/day. Over 60% consumed less than the estimated average requirement for calcium, folate, magnesium and selenium. Thirteen (28.3%) dancers had suboptimal iron status (serum ferritin (SF) ballet dancers are at risk for iron deficiency, and possibly inadequate nutrient intakes.

Objective Preliminary test of a manualized, measurement-guided treatment for depression for adolescents and young adults in care at four sites of the Adolescent Trials Network for HIV/AIDS Interventions (ATN). Design The U.S. sites were randomly assigned to either a 24-week, combination cognitive behavioral therapy and medication management algorithm (COMB) tailored for youth living with HIV (YLWH) or to treatment as usual (TAU). Methods Youth at TAU sites had access to therapists and medication management as needed. COMB site clinicians were trained in the manualized intervention and participated in supervision calls to monitor intervention fidelity. Results Over the course of the study with 44 participants, those in COMB, compared to those in TAU, reported fewer depressive symptoms, p<0.01 (as measured by the Quick Inventory for Depression Symptomatology) and were more likely to be in remission, p<0.001, (65% vs.10% at week 24 end of treatment, and 71% vs. 7% at week 48 final follow-up). A greater proportion of COMB participants received psychotherapy (95% vs. 45%, p<0.001) and attended more sessions (12.6 vs. 5, p<0.001) than those in TAU. Viral load decreased in both groups and was associated (p<0.05) with reduction in depressive symptoms. Conclusions A 24-week manualized, measurement-guided psychotherapy and medication management algorithm tailored for YLWH was more effective in achieving and sustaining remission from depression than treatment as usual at HIV care clinic sites. Given observed treatment efficacy, this structured combination treatment could be disseminated to medical clinics in order to successfully treat YLWH, who are at particular risk for depression.

There are discrepancies in the literature about the role of teasing in the onset of eating pathology. This article aims to establish the influence of teasing in abnormal eating behaviors and attitudes in the adolescent population. This is a two-year prospective study conducted in 7,167 adolescents between 13 and 15 years of age. In a first assessment, teasing about weight and teasing about abilities were measured by means of the POTS.questionnaire. Its association with eating psychopathology after two years was analyzed controlling nutritional status (BMI), body dissatisfaction, drive to thinness, perfectionism (EDI), emotional symptoms and hyperactivity (SDQ) which had also been measured in the first assessment. The analysis was carried out independently for both genders. The multivariant analysis found no significant or independent effect of teasing about weight or teasing about abilities in the onset of later eating psychopathology. The obtained models were similar for both genders although in girls, but not in boys, controlling BMI was enough to make any effect of teasing disappear. Teasing about weight or abilities has no direct effect, neither in boys nor in girls of 13 to 15 years old, in the development of eating psychopathology. Copyright © 2017 SEP y SEPB.

Full Text Available Background: The purpose of this study was to evaluate the validity and reliability on the Persian translation of the Modifiable Activity Questionnaire (MAQ in a sample of Tehranian adolescents. Methods: Of a total of 52 subjects, a sub-sample of 40 participations (55.0% boys was used to assess the reliability and the validity of the physical activity questionnaire. The reliability of the two MAQs was calculated by intraclass correlation coefficients, and validation was evaluated using Pearson correlation coefficients to compare data between mean of the two MAQs and mean of four physical activity records. Results: Intraclass correlation coefficient was calculated to assess the reliability between two MAQs and the results of leisure time physical activity over the past year were 0.97. Pearson correlation coefficients between mean of two MAQs and mean of four physical activity records were 0.49 (P < 0.001, for leisure time physical activities. Conclusions: High reliability and relatively moderate validity were found for the Persian translation of the MAQ in a Tehranian adolescent population. Further studies with large sample size are suggested to assess the validity more precisely.

Lesbian and gay individuals have been reported to show more interest in other-sex, and/or less interest in same-sex, toys, playmates, and activities in childhood than heterosexual counterparts. Yet, most of the relevant evidence comes from retrospective studies or from prospective studies of clinically referred, extremely gender nonconforming children. In addition, findings are mixed regarding the relation between childhood gender-typed behavior and the later sexual orientation spectrum from exclusively heterosexual to exclusively lesbian/gay. The current study drew a sample (2,428 girls and 2,169 boys) from a population-based longitudinal study, and found that the levels of gender-typed behavior at ages 3.5 and 4.75 years, although less so at age 2.5 years, significantly and consistently predicted adolescents' sexual orientation at age 15 years, both when sexual orientation was conceptualized as 2 groups or as a spectrum. In addition, within-individual change in gender-typed behavior during the preschool years significantly related to adolescent sexual orientation, especially in boys. These results suggest that the factors contributing to the link between childhood gender-typed behavior and sexual orientation emerge during early development. Some of those factors are likely to be nonsocial, because nonheterosexual individuals appear to diverge from gender norms regardless of social encouragement to conform to gender roles.

Full Text Available Background Anxiety and depression co-occur in children and adolescents with anxiety commonly preceding depression. Although there is some evidence to suggest that the association between early anxiety and later depression is explained by a shared genetic aetiology, the contribution of environmental factors is less well examined and it is unknown whether anxiety itself is a phenotypic risk factor for later depression. These explanations of the association between early anxiety and later depression were evaluated. Methods Anxiety and depressive symptoms were assessed longitudinally in a U.K. population-based sample of 676 twins aged 5–17 at baseline. At baseline, anxiety and depression were assessed by parental questionnaire. Depression was assessed three years later by parental and adolescent questionnaire. Results Shared genetic effects between early anxiety and later depression were found. A model of a phenotypic risk effect from early anxiety on later depression provided a poor fit to the data. However, there were significant genetic effects specific to later depression, showing that early anxiety and later depression do not index entirely the same genetic risk. Conclusions Anxiety and depression are associated over time because they share a partly common genetic aetiology rather than because the anxiety phenotype leads to later depression.

Hyperlipidemia is a known risk factor of coronary artery disease. The reduction of elevated serum total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) levels in childhood may reduce cardiovascular morbidity and mortality in adulthood. Aim of the study was to assess prevalence and trends in lipid profile and lipid disorders in adolescent population in Novosibirsk (1989-2003). Four cross-sectional surveys of school children aged 14-17 years in 1989 (n=656), in 1994 (n=620), in 1999 (n=626) and in 2003 (n=667) were carried out. Total sample was 2569 (1214 males and 1355 females). Blood total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), triglycerides (TG) were measured by enzymatic methods. LDL-C was calculated with Friedwald's formula. Associations of blood lipids with age, sex, year of study, body mass index (kg/m2), blood pressure and main nutrients of diet were measured by GLM method. Prevalence of dyslipidemia was evaluated with NCEP-peds criteria. Diet was estimated using 24-hour dietary recall. During the 15-year period (1989-2003) mean serum TC decreased from 175 to 162 mg/dl in males and from 191 to 175 mg/dl in females (p dislipidemias in adolescents of Novosibirsk significantly changed following the changes of body mass index and diet.

The association of acne and self-evaluation is barely explored among late adolescents in the general population. We sought to explore self-esteem, body satisfaction, and acne among 18-year-old young adults at a community level. We conducted a questionnaire-based survey among 3775 late adolescents. Our response rate was 80%. The prevalence of acne was 13.5%. Girls and boys with acne had significantly more depressive symptoms, lower self-attitude, more feelings of uselessness, fewer feelings of pride, lower self-worth, and lower body satisfaction than those without acne. In a regression model adjusting for body mass index and depressive symptoms, acne explained significantly poor self-attitude for boys only (odds ratio 2.07 [confidence interval 1.10; 3.88]) and poor self-worth for girls only (odds ratio 1.88 [confidence interval 1.23; 2.88]). Not all items of the self-esteem instrument were included. At age 18 years, acne is related to self-evaluation independent of body mass index and depressive symptoms.

Despite considerable progress in diagnostic methods and treatment options, cardiovascular diseases constitute a serious health issue in Poland, and hypertension is considered one of the main risk factors in the incidence of the diseases. The aim of this study is to assess the values of arterial blood pressure among adolescents in the context of urban and rural environments. The study was carried out on a representative, randomly selected group of youths aged 10-18 years, participating in the ADOPOLNOR project. Prior to blood pressure measurement, each pupil was assessed according to anthropomorphic principles. The BP measurements strictly followed the guidelines of the Fourth Protocol of the American Working Group of High Blood pressure in Children and Adolescents. Mean values of systolic blood pressure (SBP) in boys in rural areas were higher in every age group than in the boys in urban areas. Higher values of systolic and diastolic blood pressure were observed also in girls in rural areas. BP values sufficiently high for the diagnosis of hypertension were observed in 12.8% of the rural boy population but only in 6.7% of the boys from the urban environment. The difference is statistically significant. The girls in rural areas (13.3%) had twice the incidence of elevated BP values in comparison with the girls in urban areas (7.2%) and, as in boys, the difference is statistically significant. The high proportion of pupils with elevated arterial blood pressure observed in the rural areas of Wielkopolska calls for regularly performed BP assessment and monitoring in this populatio.

A decrease in live donor pediatric kidney transplants has occurred in the United States. This study investigates barriers that may influence access to live donor kidney transplants in children. Retrospective chart review was conducted for 91 children (69% male, mean age 11.9 years) who underwent pretransplant workup from 2005 to 2015 at an urban pediatric hospital. Fifty-four percent were African American, 32% Caucasian, 8% Arabic, 3% Hispanic, and 3% Others. Government-sponsored insurance (Medicaid/Medicare) was utilized by 73%, and 54% had dual caregivers. Only nine of 68 kidney transplants were live donor transplants. Live donor transplants (11%) were significantly (P=.008) lower than deceased donor transplants (59%) in African Americans. Private insurance was reported by 56% of live donor recipients and 25% of deceased donor recipients. Among live donor recipients, 78% were from dual caregiver families. Caregiver, health-related, financial, and religious/cultural barriers to live donor transplants were reported, several of which may be amenable to positive intervention.

This study examines the sociodemographic characteristics of people living near industrial sources of air pollution in three areas of the United States: (1) the Kanawha Valley in West Virginia: (2) the Baton Rouge-New Orleans corridor in Louisiana: and (3) the greater Baltimore metropolitan area in Maryland. Using data from the 1990 Toxics Release Inventory (TRI) and the 1990 Census, we analyze relationships between variables assumed to be independent, such as location of single or multiple industrial emission sources, and the dependent variables of race (black/white) and poverty status (above/below poverty level). Results from all three study areas are consistent and indicate that African Americans and those living in households defined to be below the established poverty level are more likely, on average, to live closer to the nearest TRI facility and to live within 2 miles of multiple TRI facilities. Conversely, whites and those living in households above the poverty level are more likely, on average, to live farther from the nearest TRI facility and to live within 2 miles of fewer facilities, compared to African Americans and poor people.

It is well known that parental and community-based support are each related to healthy development in lesbian, gay, bisexual, transgender, queer, and questioning (LGBTQ) youth, but little research has explored the ways these contexts interact and overlap. Through go-along interviews (a method in which participants guide the interviewer around the community) with 66 youth in British Columbia, Massachusetts, and Minnesota, adolescents (aged 14-19 years) reported varying extent of overlap between their LGBTQ experiences and their parent-youth experiences; parents and youth each contributed to the extent of overlap. Youth who reported high overlap reported little need for resources outside their families but found resources easy to access if wanted. Youth who reported little overlap found it difficult to access resources. Findings suggest that in both research and practice, considering the extent to which youth feel they can express their authentic identity in multiple contexts may be more useful than simply evaluating parental acceptance or access to resources.

Suicidal attempts are steadily increasing in societies with rapid urbanisation and dramatic social changes in places like Istanbul. Stress related to internal migration may increase suicidal behaviour. We investigated the impact of internal migration and culture on suicide attempts among youth in Istanbul. We retrospectively analysed the records of 210 children and adolescents, aged 6-18 years, who presented at the Emergency Outpatient Clinic of the Department of Pediatrics at Cerrahpaşa Medical School in Istanbul because of suicide attempts between January 2008 and December 2010. The majority of patients (78.95%, N = 165) had a background of internal migration, mostly (65%, N = 136) originating from regions with large cultural differences compared with that of Istanbul. Noticeably, more migrants than non-migrants (18.8% vs. 6.8%) and more patients originating from regions with large cultural differences chose high-risk methods for suicide attempts (20.7% vs. 8.1%). Internal migration can be considered a serious risk factor for suicidal behaviour. Furthermore, the degree of cultural differences between the area of origin and the new environment can be of vital importance. Healthcare measures should, therefore, focus on internal migration as a risk factor for youth suicidal behaviour and provide assistance for appropriate resettlement and integration in countries with increased mobility.

A 13 X-chromosomal short tandem repeat (STR) multiplex system (DXS6807, DXS8378, DSX9902, DXS7132, DXS9898, DXS6809, DXS6789, DXS7424, DXS101, GATA172D05, HPRTB, DXS8377, and DXS7423) was tested on 1,037 DNA samples from eight population groups currently living in Taiwan. Different distributions of the allelic frequencies in different populations were presented. DXS8377 and DXS101 were the two most polymorphic loci in these eight populations, whereas DXS7423 was the least informative marker in most of the populations studied. The genetic distances between the populations and the constructed phylogenetic tree revealed a long genetic distance between Asian and Caucasian populations as well as isolation of the Tao population. The phylogenetic tree grouped populations into clusters compatible with their ethnogeographic relationships. This 13 X-chromosomal short tandem repeat multiplex system offers a considerable number of polymorphic patterns in different populations. This system can be useful in forensic identification casework and ethnogeographic research.
Psychotic symptoms occur more frequently in the general population than psychotic disorder and index risk for psychopathology. Multiple studies have reported on the prevalence of these symptoms using self-report questionnaires or clinical interviews but there is a lack of consensus about the prevalence of psychotic symptoms among children and adolescents.

Background Smoking scenes in movies promote adolescent smoking onset; thus, the analysis of the number of images of smoking in movies really reaching adolescents has become a subject of increasing interest. Objective The aim of this study was to estimate the level of exposure to images of smoking in movies watched by adolescents in Argentina and Mexico. Methods First-year secondary school students from Argentina and Mexico were surveyed. One hundred highest-grossing films from each year of the period 2009-2013 (Argentina) and 2010-2014 (Mexico) were analyzed. Each participant was assigned a random sample of 50 of these movies and was asked if he/she had watched them. The total number of adolescents who had watched each movie in each country was estimated and was multiplied by the number of smoking scenes (occurrences) in each movie to obtain the number of gross smoking impressions seen by secondary school adolescents from each country. Results Four-hundred and twenty-two movies were analyzed in Argentina and 433 in Mexico. Exposure to more than 500 million smoking impressions was estimated for adolescents in each country, averaging 128 and 121 minutes of smoking scenes seen by each Argentine and Mexican adolescent, respectively. Although 15, 16 and 18-rated movies had more smoking scenes in average, movies rated for younger teenagers were responsible for the highest number of smoking scenes watched by the students (67.3% in Argentina and 54.4% in Mexico) due to their larger audience. Conclusion At the population level, movies aimed at children are responsible for the highest tobacco burden seen by adolescents. PMID:27354756

In Germany, smoking prevalence among adolescents has significantly declined since the early 2000s. However, data show that adolescent smoking rates considerably differ between different types of secondary schools. The aim of our study was to examine how educational inequalities in adolescent smoking behaviour have developed over time. Data were used from four population-based studies (each consisting of repeated cross-sectional surveys from 2001-2015): the representative surveys of the Federal Centre for Health Education, the German Health Interview and Examination Survey for Children and Adolescents, the Health Behaviour in School-aged Children Study, and the European School Survey Project on Alcohol and Other Drugs. Each study comprised different age groups (within the age range of 11-17 years) and used different smoking measures. Adolescents' educational status was based on the attended type of secondary school. Absolute and relative educational inequalities were presented as prevalence differences and prevalence ratios, respectively. Despite methodical differences, all four studies similarly reveal that adolescent smoking rates have significantly declined in all educational groups. However, lower smoking rates among secondary school students attending higher educational tracks could be observed. While absolute educational inequalities tended to decrease over time, relative inequalities between educational groups remained rather stable or even increased. Declining adolescent smoking rates suggest that smoking may have lost some of its attractiveness for young people. Our findings further emphasize the importance of tobacco control measures such as raising cigarette taxes, smoking bans, and increasing minimum legal age for tobacco purchase. As relative educational inequalities in adolescent smoking rates did not diminish over time, setting- and target group-specific interventions should focus more on students in middle and lower secondary school tracks.

An increase in the prevalence of pediatric type 2 diabetes mellitus (T2DM) has been reported by numerous studies in the United States during the past two decades. Available data from Europe are scarce, but also suggest the rising prevalence of this disease in overweight children. The aim of this study was to determine the prevalence of previously undiagnosed T2DM, impaired fasting glucose (IFG) and impaired glucose tolerance (IGT) in a clinic cohort of otherwise healthy overweight and obese Caucasian children and adolescents living in Serbia. The study group consisted of 301 subjects (176 girls, 125 boys) aged 5.2-18.9 years, with body mass index >90th percentile. Oral glucose tolerance test was performed in all subjects. Previously undiagnosed T2DM was discovered in 0.3% (n=1) and impaired glucose regulation in 15.9% (n=48) of the subjects. Isolated IFG was detected in 4.3% (n=13), isolated IGT in 8.3% (n=25) and combined IFG and IGT in 3.3% (n=10) of the subjects. Disturbances of glucose metabolism were present in a substantial number of the subjects, which emphasizes the need for prevention and treatment of childhood obesity.

This research aims to investigate the rate and nature of anxiety symptoms in a group of children and adolescents living with chronic illnesses in Jordan, and their relation to social desirability in a cultural sample not previously researched. Using the Revised Children's Manifest Anxiety Scale (R-CMAS), anxiety and social desirability data were obtained from 114 children diagnosed with chronic illnesses and 162 healthy control participants. Based on children's self-report, participants were categorized according to their adaptive style paradigm as either high anxious, low anxious, or repressor. It was proposed that children who score high on social desirability and low on anxiety are repressors. The prevalence of these categories was compared across the two groups. Anxiety was reported in 9.64 percent of the chronic illnesses and 12.34 percent of the healthy peers. Using the data obtained in the present study, the rate and nature of anxiety in children with chronic illnesses were lower for children in Jordan when compared to previous studies. However, social desirability values were similar to those established in Western societies suggesting a significantly higher percentage of children identified as repressors in children with long-term illnesses. These results supported the hypothesis regarding the relationship between social desirability and expressed anxiety symptoms. © The Author(s) 2012.

Socioeconomic deprivation is associated with higher renal replacement therapy acceptance rates in the UK but lower rates of living kidney transplantation. This study examines donor-recipient relationship patterns with socioeconomic deprivation in the white population of England. Demographic characteristics of all white live renal transplant donors and recipients between 2001 and 2010 in England were analyzed. Patterns of donor-recipient relationship were analyzed to see whether they differed according to an ecological measure of socioeconomic status (Index of Multiple Deprivation). Group comparisons were performed using chi-square tests and multivariable logistic regression. Sources of living kidney transplants differed with deprivation (p relative" donor and less likely from spouses/partners. Logistic regression suggested differences seen with spouse/partner donations with deprivation were explained by differences in the age and gender of the recipients. The source of living kidneys differs by level of area deprivation. Given the disparity in rates of living kidney transplants between the most and least socioeconomically deprived, there is a need to understand the reasons behind these observed relationship differences, with the aim of increasing transplantation rates in the most deprived. © 2013 John Wiley & Sons A/S.

Previous research has consistently documented the importance of VIPs (mentors or important non-parental adults) in the lives of adolescents. Little is known, however, about whether VIPs play the same important roles across ethnic groups and whether VIPs remain influential when adolescents are older and involved in romantic relationships. The present study compared VIPs of 355 Hispanic, Asian, and European American older adolescents (age range = 17-19 years; M = 18.7 years; 62% female). Results indicated that, despite ethnic differences in their social capital, VIPs' psychological characteristics (e.g., warmth and acceptance, depressive symptoms, and problem behavior) were similar. VIPs were perceived to have more positive psychological profiles than parents and peers, and in some cases, romantic partners. Moreover, with a few exceptions, the associations between VIP characteristics and adolescent adjustment (e.g., self-esteem, depressive symptoms, and problem behavior) were largely similar across ethnic groups. Finally, VIPs made unique contributions to adolescents' self-esteem and problem behaviors even after the effects of romantic partners were considered. Implications of the findings are discussed.

The purpose of this study was to investigate the overall use of assistive devices among persons with age-related macular degeneration (ARMD) and how it is related to dependence in daily activities. This was a retrospective, descriptive, cross-sectional population study of 85-year-olds. The most common category of assistive devices was bathing devices followed by mobility devices. The overall use of assistive devices was 82%, and around 80% of the device users were independent in activities of daily living. They were multiple device users (57%) and used more mobility devices and personal assistance in mobility. In conclusion, the ARMD group comprises very frequent users of assistive devices and uses assistive devices to remain independent. This implies that health services should provide assistive devices at an early stage in the disablement process to avoid the development of dependence and should consider the likelihood of multiple health problems when assessing the needs of assistive devices among persons with ARMD.

Full Text Available OBJECTIVE: Birth defects are an increasing health priority worldwide, and the subject of a major 2010 World Health Assembly Resolution. Excess cancer risk may be an added burden in this vulnerable group of children, but studies to date have provided inconsistent findings. This study assessed the risk for cancer in children and young adolescents with major birth defects. METHODS AND FINDINGS: This retrospective, statewide, population-based, cohort study was conducted in three US states (Utah, Arizona, Iowa. A cohort of 44,151 children and young adolescents (0 through 14 years of age with selected major, non-chromosomal birth defects or chromosomal anomalies was compared to a reference cohort of 147,940 children without birth defects randomly sampled from each state's births and frequency matched by year of birth. The primary outcome was rate of cancer prior to age 15 years, by type of cancer and type of birth defect. The incidence of cancer was increased 2.9-fold (95% CI, 2.3 to 3.7 in children with birth defects (123 cases of cancer compared to the reference cohort; the incidence rates were 33.8 and 11.7 per 100,000 person-years, respectively. However, the excess risk varied markedly by type of birth defect. Increased risks were seen in children with microcephaly, cleft palate, and selected eye, cardiac, and renal defects. Cancer risk was not increased with many common birth defects, including hypospadias, cleft lip with or without cleft palate, or hydrocephalus. CONCLUSION: Children with some structural, non-chromosomal birth defects, but not others, have a moderately increased risk for childhood cancer. Information on such selective risk can promote more effective clinical evaluation, counseling, and research.

This is a retrospective review of pedicle screw placement in adolescent idiopathic scoliosis (AIS) patients under 18 years of age who underwent robot-assisted corrective surgery. Our primary objective was to characterize the accuracy of pedicle screw placement with evaluation by computed tomography (CT) after robot-assisted surgery in AIS patients. Screw malposition is the most frequent complication of pedicle screw placement and is more frequent in AIS. Given the potential for serious complications, the need for improved accuracy of screw placement has spurred multiple innovations including robot-assisted guidance devices. No studies to date have evaluated this robot-assisted technique using CT exclusively within the AIS population. Fifty patients were included in the study. All operative procedures were performed at a single institution by a single pediatric orthopedic surgeon. We evaluated the grade of screw breach, the direction of screw breach, and the positioning of the patient for preoperative scan (supine versus prone). Of 662 screws evaluated, 48 screws (7.2 %) demonstrated a breach of greater than 2 mm. With preoperative prone position CT scanning, only 2.4 % of screws were found to have this degree of breach. Medial malposition was found in 3 % of screws, a rate which decreased to 0 % with preoperative prone position scanning. Based on our results, we conclude that the proper use of image-guided robot-assisted surgery can improve the accuracy and safety of thoracic pedicle screw placement in patients with adolescent idiopathic scoliosis. This is the first study to evaluate the accuracy of pedicle screw placement using CT assessment in robot-assisted surgical correction of patients with AIS. In our study, the robot-assisted screw misplacement rate was lower than similarly constructed studies evaluating conventional (non-robot-assisted) procedures. If patients are preoperatively scanned in the prone position, the misplacement rate is further

The objective of this research is to determine the validity and reliability of a questionnaire designed to specifically assess the knowledge of HIV and other sexually transmitted infections in a Spanish adolescent population. Cross-sectional study for the validation of a questionnaire. A total of 17 schools in five Spanish provinces. A total of 1,570 adolescent schoolchildren between 13 and 17 years old. A pool of 40 items relating to knowledge about HIV and other sexually transmitted infections was established. This pool was analyzed by an expert panel. It was then administered to a pilot group with the same demographic characteristics of the sample, to ensure comprehension. Item analysis, internal consistency, test/retest and exploratory factorial analysis. A factor analysis was performed, in which five factors that explained 46% of the total variance were retained: general knowledge about HIV, condom as a protective method, routes of HIV transmission, the prevention of HIV, and other sexually transmitted infections. Reliability measures ranged from 0.66 to 0.88. The test-retest correlation was 0.59. There were gender differences in the knowledge of infections. These factors have adequate internal consistency and acceptable test-retest correlation. Theoretically, these factors fit properly with the content of the items. The factors have a moderate relationship, indicating that a high degree of knowledge about an aspect, but not a guarantee of general knowledge. The availability of a questionnaire to assess knowledge of sexually transmitted infections is helpful to evaluate prevention programs. Copyright © 2014 Elsevier España, S.L.U. All rights reserved.

Full Text Available Evidence has accumulated in recent decades on the drastic impact of climate change on biodiversity. Warming temperatures have induced changes in species physiology, phenology, and have decreased body size. Such modifications can impact population dynamics and could lead to changes in life cycle and demography. More specifically, conceptual frameworks predict that global warming will severely threaten tropical ectotherms while temperate ectotherms should resist or even benefit from higher temperatures. However, experimental studies measuring the impacts of future warming trends on temperate ectotherms' life cycle and population persistence are lacking. Here we investigate the impacts of future climates on a model vertebrate ectotherm species using a large-scale warming experiment. We manipulated climatic conditions in 18 seminatural populations over two years to obtain a present climate treatment and a warm climate treatment matching IPCC predictions for future climate. Warmer temperatures caused a faster body growth, an earlier reproductive onset, and an increased voltinism, leading to a highly accelerated life cycle but also to a decrease in adult survival. A matrix population model predicts that warm climate populations in our experiment should go extinct in around 20 y. Comparing our experimental climatic conditions to conditions encountered by populations across Europe, we suggest that warming climates should threaten a significant number of populations at the southern range of the distribution. Our findings stress the importance of experimental approaches on the entire life cycle to more accurately predict population and species persistence in future climates.

The pink hibiscus mealybug Maconellicoccus hirsutus (Green) is a dangerous pest that damages a wide variety of agricultural, horticultural, and forestry crops. Amplified fragment length polymorphism (AFLP) fingerprints were used to characterize the genetic variation of 11 M. hirsutus populations infesting three plant species in Nayarit, Mexico. Analysis was carried out using four primers combinations, producing 590 polymorphic bands. Cluster analysis, as well as bootstrap dendrogram and nonmetric multidimensional scaling analysis, grouped M. hirsutus populations according to their host plant. The estimated F(ST) values indicated a high differentiation in M. hirsutus populations among the three host plant species. These results were also supported by a Bayesian analysis, which indicated a population clustering robustness according to their host plant. Genetic variation among populations is not caused by geographic distances, as shown by a Mantel test.

Full Text Available Abstract Background Harmful social conditions in early life might predispose individuals to dental status which in turn may impact on adolescents' quality of life. Aims To estimate the prevalence of oral health impacts among 12 yr-old Brazilian adolescents (n = 359 and its association with life course socioeconomic variables, dental status and dental services utilization in a population-based birth cohort in Southern Brazil. Methods Exploratory variables were collected at birth, at 6 and 12 yr of age. The Oral Impacts on Daily Performances index (OIDP was collected in adolescence and it was analyzed as a ranked outcome (OIDP from 0 to 9. Unadjusted and adjusted multivariable Poisson regression with robust variance was performed guided by a theoretical determination model. Results The response rate was of 94.4% (n = 339. The prevalence of OIDP = 1 was 30.1% (CI95%25.2;35.0 and OIDP ≥ 2 was 28.0% (CI95%23.2;32.8. The most common daily activity affected was eating (44.8%, follow by cleaning the mouth and smiling (15.6%, and 15.0%, respectively. In the final model mother schooling and mother employment status in early cohort participant's life were associated with OIDP in adolescence. As higher untreated dental caries at age 6 and 12 years, and the presence of dental pain, gingival bleeding and incisal crowing in adolescence as higher the OIDP score. On the other hand, dental fluorosis was associated with low OIDP score. Conclusion Our findings highlight the importance of adolescent's early life social environmental as mother schooling and mother employment status and the early and later dental status on the adolescent's quality of life regardless family income and use of dental services.

Full Text Available The bivalve Arctica islandica is extremely long lived (>400 years and can tolerate long periods of hypoxia and anoxia. European populations differ in maximum life spans (MLSP from 40 years in the Baltic to >400 years around Iceland. Characteristic behavior of A. islandica involves phases of metabolic rate depression (MRD during which the animals burry into the sediment for several days. During these phases the shell water oxygen concentrations reaches hypoxic to anoxic levels, which possibly support the long life span of some populations. We investigated gene regulation in A. islandica from a long-lived (MLSP 150 years German Bight population and the short-lived Baltic Sea population, experimentally exposed to different oxygen levels. A new A. islandica transcriptome enabled the identification of genes important during hypoxia/anoxia events and, more generally, gene mining for putative stress response and (anti- aging genes. Expression changes of a antioxidant defense: Catalase, Glutathione peroxidase, manganese and copper-zinc Superoxide dismutase; b oxygen sensing and general stress response: Hypoxia inducible factor alpha, Prolyl hydroxylase and Heat-shock protein 70; and c anaerobic capacity: Malate dehydrogenase and Octopine dehydrogenase, related transcripts were investigated. Exposed to low oxygen, German Bight individuals suppressed transcription of all investigated genes, whereas Baltic Sea bivalves enhanced gene transcription under anoxic incubation (0 kPa and, further, decreased these transcription levels again during 6 h of re-oxygenation. Hypoxic and anoxic exposure and subsequent re-oxygenation in Baltic Sea animals did not lead to increased protein oxidation or induction of apoptosis, emphasizing considerable hypoxia/re-oxygenation tolerance in this species. The data suggest that the energy saving effect of MRD may not be an attribute of Baltic Sea A. islandica chronically exposed to high environmental variability (oxygenation

Cyclosporine is often used to prevent allograft rejection in renal transplant recipients. However, cyclosporine has a narrow therapeutic window and large variability in its pharmacokinetics. Individual characteristics and genetic polymorphisms can cause the variation. Hence, it is important to determine the cause(s) of the variation in cyclosporine pharmacokinetics. To our knowledge, this is the first reported population pharmacokinetic study of cyclosporine in living donor renal transplant recipients that considered the genetic polymorphism as a covariate. To build a population pharmacokinetic model of cyclosporine in living donor renal transplant recipients and identify covariates including CYP3A5*3, ABCB1 genetic polymorphisms that affect cyclosporine pharmacokinetic parameters. Clinical characteristics and cyclosporine concentration data for 69 patients who received cyclosporine-based immunosuppressive therapy after living donor renal transplantation were collected retrospectively for up to 400 postoperative days. CYP3A5*1/*3 and ABCB1C1236T, G2677T/A, C3435T geno-typing was performed. A population pharmacokinetic analysis was conducted using a NONMEM program. After building the final model, 1000 bootstrappings were performed to validate the final model. In total, 2034 blood samples were collected. A 1-compartment open model with first-order absorption and elimination was chosen to describe the pharmacokinetics of cyclosporine. A population pharmacokinetic analysis showed that postoperative days, sex, and CYP3A5 genotype significantly affected the pharmacokinetics of cyclosporine. The final estimate of mean clearance was 56 L/h, and the mean volume of distribution was 4650 L. The interindividual variability for these parameters was 22.98% and 51.48%, respectively. Using the present model to calculate the dose of cyclosporine with CYP3A5 genotyping can be possible for the patients whose cyclosporine concentration is not within the therapeutic range even with

the aim of this study was to review systematically the prevalence of headache and migraine in children and adolescents and to study the influence of sex, age, and region of residence on the epidemiology. we systematically searched the literature in electronic databases to cover the period between 1 January 1990 and 31 December 2007. We assessed and included population-based studies on epidemiology of headache and migraine in children and adolescents if they fulfilled the following criteria: (1) reporting on unselected childhood population; (2) reliable methods of data collection using a questionnaire or face-to-face interviews; (3) using the International Headache Society's (IHS) criteria (1988 or 2004) for the diagnosis of migraine; and (4) provision of sufficient and explicit data for analysis. We used Excel, Stata, and Confidence Interval Analysis software. we identified and analysed 50 population-based studies reporting the prevalence of headache and/or migraine in children and adolescents (headache over periods between 1 month and lifetime in children and adolescents is 58.4% (95% confidence interval [CI] 58.1-58.8). Females are more likely to have headache than males (odds ratio [OR] 1.53, 95% CI 1.48-1.6). The prevalence of migraine over periods between 6 months and lifetime is 7.7% (95% CI 7.6-7.8). Females are more likely than males to have migraine (OR 1.67, 95% CI 1.60-1.75). Regional differences in prevalence of migraine, though statistically significant, may not be of clinical significance. The change in the IHS's criteria for the diagnosis of migraine was not associated with any significant change in the prevalence of migraine. this study confirms the global high prevalence of headache and migraine in children and adolescents. Sex, age, and regional differences are evident.
Full Text Available Objective. The present study was designed to investigate the prevalence of different combinations of the metabolic syndrome (MetS risk factors among a nationally representative sample of adolescents in the Middle East and North Africa (MENA. Methods. The study sample, obtained as part of the third study of the school-based surveillance system entitled CASPIAN III, was representative of the Iranian adolescent population aged from 10 to 18 years. The prevalence of different components of MetS was studied and their discriminative value was assessed by receiver operating characteristic (ROC curve analysis. Results. The study participants consisted of 5738 students (2875 girls with mean age of 14.7±2.4 years living in 23 provinces in Iran; 17.4% of participants were underweight and 17.7% were overweight or obese. Based on the criteria of the International Diabetes Federation for the adolescent age group, 24.2% of participants had one risk factor, 8.0% had two, 2.1% had three, and 0.3% had all the four components of MetS. Low HDL-C was the most common component (43.2% among the overweight/obese versus 34.9% of the normal-weight participants, whereas high blood pressure was the least common component. The prevalence of MetS was 15.4% in the overweight/obese participants, the corresponding figure was 1.8% for the normal-weight students, and 2.5% in the whole population studied. Overweight/obese subjects had a 9.68 increased odds of (95% CI: 6.65–14.09 the MetS compared to their normal-weight counterparts. For all the three risk factors, AUC ranged between 0.84 and 0.88, 0.83 and 0.87, and 0.86 and 0.89 in waist circumference, abdominal obesity, and BMI for boys and between 0.78 and 0.97, 0.67 and 0.93, and 0.82 and 0.96 for girls, respectively. Conclusion. The findings from this study provide alarming evidence-based data on the considerable prevalence of obesity, MetS, and CVD risk factors in the adolescent age group. These results are confirmatory

Full Text Available Abstract Background Rare species have seldom been studied in marine habitats, mainly because it is difficult to formally assess the status of rare species, especially in patchy benthic organisms, for which samplings are often assumed to be incomplete and, thus, inappropriate for establishing the real abundance of the species. However, many marine benthic invertebrates can be considered rare, due to the fragmentation and rarity of suitable habitats. Consequently, studies on the genetic connectivity of rare species in fragmented habitats are basic for assessing their risk of extinction, especially in the context of increased habitat fragmentation by human activities. Sponges are suitable models for studying the intra- and inter-population genetic variation of rare invertebrates, as they produce lecitotrophic larvae and are often found in fragmented habitats. Results We investigated the genetic structure of a Mediterranean sponge, Scopalina lophyropoda (Schmidt, using the allelic size variation of seven specific microsatellite loci. The species can be classified as "rare" because of its strict habitat requirements, the low number of individuals per population, and the relatively small size of its distribution range. It also presents a strong patchy distribution, philopatric larval dispersal, and both sexual and asexual reproduction. Classical genetic-variance-based methods (AMOVA and differentiation statistics revealed that the genetic diversity of S. lophyropoda was structured at the three spatial scales studied: within populations, between populations of a geographic region, and between isolated geographic regions, although some stochastic gene flow might occur among populations within a region. The genetic structure followed an isolation-by-distance pattern according to the Mantel test. However, despite philopatric larval dispersal and fission events in the species, no single population showed inbreeding, and the contribution of clonality to the

Population explosion is considered to be one of the most crucial problems in the world. However, in Japan, the opposite problem: population decline has become serious now. Japanese population is estimated to decrease by twenty millions in 2040. This negative situation will cause to increase areas where many residents cannot make a daily living all over Japan because many convenience living facilities such as supermarkets, convenience stores and drugstores will be difficult to maintain their market area population due to future population decline. In our research, we used point data of convenience living facilities developed by address geocoding of digital telephone directory and point data of future population projection developed by distribution of Japanese official population projection data proportionally among the building volume of digital residential map, which can monitor building volumes all over Japan. In conclusion, we estimated that various convenience living facilities in Japan will shrink and close by population decline in near future. In particular, it is cleared that approximately 14.7% of supermarkets will be possible to withdraw all over Japan by 2040. In addition, it is cleared that over 40% of supermarkets in some countryside prefectures will be possible to withdraw by 2040. Thus, we estimated future distributions of convenience living facilities that cannot maintain their market area population due to future population decline. Moreover, we estimated the number of people that they will become inconvenience in buying fresh foods.
Full Text Available Background. HPV vaccination may prevent thousands of cases of cervical cancer. We aimed to evaluate the understanding and acceptance of the HPV vaccine among adolescents. Methods. A questionnaire was distributed to adolescents at health clinics affiliated with a large urban hospital system to determine knowledge pertaining to sexually transmitted diseases and acceptance of the HPV vaccine. Results. 223 adolescents completed the survey. 28% were male, and 70% were female. The mean age for respondents was 16 years old. Adolescents who had received the HPV vaccine were more likely to be female and to have heard of cervical cancer and Pap testing. Of the 143 adolescents who had not yet been vaccinated, only 4% believed that they were at risk of HPV infection and 52% were willing to be vaccinated. Conclusions. Surveyed adolescents demonstrated a marginal willingness to receive the HPV vaccine and a lack of awareness of personal risk for acquiring HPV.

Regulated gene transcription is dependent on the steady-state concentration of DNA-binding and coregulatory proteins assembled in distinct regions of the cell nucleus. For example, several different transcriptional coactivator proteins, such as the Glucocorticoid Receptor Interacting Protein (GRIP), localize to distinct spherical intranuclear bodies that vary from approximately 0.2-1 micron in diameter. We are using multi-spectral wide-field microscopy of cells expressing coregulatory proteins labeled with the fluorescent proteins (FP) to study the mechanisms that control the assembly and distribution of these structures in living cells. However, variability between cells in the population makes an unbiased and consistent approach to this image analysis absolutely critical. To address this challenge, we developed a protocol for rigorous quantification of subnuclear organization in cell populations. Cells transiently co-expressing a green FP (GFP)-GRIP and the monomeric red FP (mRFP) are selected for imaging based only on the signal in the red channel, eliminating bias due to knowledge of coregulator organization. The impartially selected images of the GFP-coregulatory protein are then analyzed using an automated algorithm to objectively identify and measure the intranuclear bodies. By integrating all these features, this combination of unbiased image acquisition and automated analysis facilitates the precise and consistent measurement of thousands of protein bodies from hundreds of individual living cells that represent the population.

Approximately 42 million adolescents aged 10-19 years, representing 13% of the population, resided in the United States in 2014 (1). Adolescence is characterized by rapid and profound physical, intellectual, emotional, and psychological changes (2), as well as development of healthy or risky behaviors that can last a lifetime. Parents have strong influence on their adolescent children's lives, and family-based programs can help parents support healthy adolescent development. Because schools are natural learning environments, implementing and improving school-based policies and programs are strategic ways to reinforce healthy behaviors and educate adolescents about reducing risky behaviors. Health care during adolescence should be tailored to meet the changing developmental needs of the adolescent while providing welcoming, safe, and confidential care. Parents, educators, care providers, public health officials, and communities should collaborate in fostering healthy environments for all adolescents, now and into the future.

A population of Xiphinema chambersi from the root zone around live oak (Quercus virginiana Mill.) trees on Jekyll Island, GA, is described using both morphological and molecular tools and compared with descriptions of type specimens. Initially, because of a few morphological differences, this nematode was thought to represent an undescribed species. However, on further examination, the morphometrics of the nematodes from live oak tend to agree with most of the morphometrics in the original description and redescription of X. chambersi except for few minor differences in V% relative to body length, slightly shorter stylet length, different c value, and the number of caudal pores. We consider these differences to be part of the normal variation within this species and accordingly image this new population of X. chambersi and redescribe the species. The new population is characterized by having females with a body length of 2.1 to 2.5 mm; lip region slightly rounded and set off from head; total stylet length 170 to 193 µm; vulva at 20.4% to 21.8% of body length; a monodelphic, posterior reproductive system; elongate, conoid tail with a blunt terminus and four pairs of caudal pores, of which two pairs are subdorsal and two subventral. Sequence data from the D2-D3 region of the 28S rRNA molecule subjected to GenBank sequence comparison using BLAST showed that the sequence had 96% and 99% similarity with X. chambersi from Alabama and Florida, respectively. Phylogenetic relationships of X. chambersi with other xiphinematids based on analysis of this DNA fragment are presented. This finding represents a new location of X. chambersi in Georgia on live oak for this species.

The analysis of autosomal short tandem repeat (STR) loci is a powerful tool in forensic genetics. We developed a multiplex system in which 15 non-Combined DNA Index System autosomal STRs (D3S1744, D4S2366, D8S1110, D10S2325, D12S1090, D13S765, D14S608, Penta E, D17S1294, D18S536, D18S1270, D20S470, D21S1437, Penta D, and D22S683) could be amplified in one single polymerase chain reaction. DNA samples from 1,098 unrelated subjects of nine population groups living in Taiwan, including Taiwanese Han, indigenous Taiwanese of Taiwan Island, Tao, mainland Chinese, Filipinos, Thais, Vietnamese, Indonesians, and Caucasians, were collected and analyzed using this system. The distributions of the allelic frequencies and the forensic parameters of each population group were presented. The combined discrimination power and the combined power of exclusion were high in all population groups tested in this study. A multidimensional scaling plot of these nine population groups based on the Reynolds' genetic distances calculated from 15 autosomal STRs was constructed, and the genetic substructure in this area was presented. In conclusion, this 15 autosomal STR multiplex system provides highly informative STR data and appears useful in forensic casework and parentage testing in different populations.
Full Text Available Abstract Background Depressive and anxiety symptoms often co-occur resulting in a debate about common and distinct features of depression and anxiety. Methods An exploratory factor analysis (EFA and a bifactor modelling approach were used to separate a general distress continuum from more specific sub-domains of depression and anxiety in an adolescent community sample (n = 1159, age 14. The Mood and Feelings Questionnaire and the Revised Children's Manifest Anxiety Scale were used. Results A three-factor confirmatory factor analysis is reported which identified a mood and social-cognitive symptoms of depression, b worrying symptoms, and c somatic and information-processing symptoms as distinct yet closely related constructs. Subsequent bifactor modelling supported a general distress factor which accounted for the communality of the depression and anxiety items. Specific factors for hopelessness-suicidal thoughts and restlessness-fatigue indicated distinct psychopathological constructs which account for unique information over and above the general distress factor. The general distress factor and the hopelessness-suicidal factor were more severe in females but the restlessness-fatigue factor worse in males. Measurement precision of the general distress factor was higher and spanned a wider range of the population than any of the three first-order factors. Conclusions The general distress factor provides the most reliable target for epidemiological analysis but specific factors may help to refine valid phenotype dimensions for aetiological research and assist in prognostic modelling of future psychiatric episodes.
Full Text Available Introduction. Oxygen is an essential element for sustaining the life of aerobes; however, in certain conditions it may be toxic for these organisms. This is due to so-called reactive oxygen species – ROS. Factors which cause the production of free radicals include ionizing radiation, UV radiation, high temperature, and hazardous substances, such as phenols, carbon monoxide, e.g. in smokers, also air pollution and drugs. Objective. The objective of the study was analysis of the total antioxidant status (TAS in stimulated and unstimulated saliva, according to the number of active carious lesions in generally healthy non-smokers aged 15–17. Materials and method. The study covered 113 adolescents aged 15–17 in whom the state of dentition was evaluated using the DMFT (Decayed-Missing-Filled index, and oral hygiene assessed based on the OHI-S (Oral Hygiene Index-Simplified index. TAS in saliva was determined by means of a Randox Labolatories Ltd. test kit, by the spectrophotometric method. Results. Based on the results of the study, it was found that in the population examined an increase in the number of carious lesions was accompanied by a significant decrease in the TAS, both in stimulated and unstimulated saliva. Conclusions. A health-promoting life style, maintenance of basic principles of oral hygiene and care of general health through the elimination of harmful habits decrease the risk of dental caries.
Full Text Available Aim: To determine the oral health status of intellectually disabled (ID children and adolescents from state schools, Valdivia, Chile, 2012. Design: Descriptive study. A sample of students from state schools was assessed for caries history (Decayed, Missing, Filled permanent Teeth (DMFT/decayed, extracted, filled temporal teeth (deft, quality of oral hygiene (Simplified Oral Hygiene Index, OHI-S and gingival health (Gingival Index, GI. In addition, questions were asked about dental care habits, degree of ID, presence of systemic disease and medicine use. Results: 195 students with slight to moderate ID and aged from 6 to 21 years were assessed. The average DMFT/deft was 2.19/1.33 for female students and 1.59/1.93 for male students. The OHI-S in 75.9% of participants was moderate, with poorer oral hygiene found in participants with moderate ID. Only 2.6% showed code 0 for GI, reflecting poor oral hygiene. Most participants possessed their own toothbrush (88.2% and could clean their teeth unaided (96.4%.Conclusion: The state of oral health in the assessed population is deficient. The quality of oral hygiene is normal or poor, which leads to poor gingival health.

Objectives: The objectives of the present study were to assess the relative impact of different pathways of environmental cadmium (Cd) exposure and to evaluate the contribution from locally produced vegetables and root crops to the total dietary intake of Cd. Methods: Cadmium in urine was determined for 492 individuals living near a closed down battery factory in Sweden. For each individual we created an environmental exposure-index based on Cd emissions to ambient air and number of years living at various distances from the plant. This information as well as dietary data were collected via questionnaires. Samples of soil, carrots and/or potatoes were collected from 37 gardens and analysed for Cd concentration. Results: Eating homegrown vegetables/potatoes, environmental Cd-exposure-index, female gender, age above 30 years and smoking more than one pack of cigarettes daily for at least 10 years were found to be significantly associated with increased urine concentrations of Cd (UCd > 1.0 nmol/mmol creatinine). We found a statistically significant relation between Cd in urine and environmental Cd-exposure-index in persons eating homegrown vegetables/potatoes regularly. Cd concentrations in homegrown carrots, potatoes and in garden soil were highest in the area closest to the factory. Daily consumption of potatoes and vegetables cultivated in the vicinity of the closed battery factory was estimated to increase Cd intake by 18-38%. Conclusion: The present study shows that consumption of locally grown vegetables and root crops was an important exposure pathway, in subjects living near a nickel-cadmium battery plant, whereas direct exposure via ambient air was less important.
Full Text Available Objectives: The aims of this study were: (i to ascertain whether the nutritional status of a population of secondary school students had improved after an educational intervention; (ii to analyze whether students had adopted healthier eating and exercise habits after participating in a health education intervention; (iii to discover whether the students spent less time on sedentary leisure activities after the intervention. Sample and methodology: The population of the sample consisted of 138 adolescents, age range was between 14-19 years old: 67 males (48.6% and 71 females (51.4%. They were students at two public secondary schools in the city of Almería (Spain. In the first phase (15-30 september 2011 of this three-phase study, the nutritional status of the students was assessed by means of anthropometry. In the second phase (1 october 2012-15 june 2012, the students participated in an educational intervention that fomented awareness of the benefits derived from healthy eating habits and physical exercise. In the third and final phase (16-31 june 2012, the effectiveness of the intervention was evaluated. Results: After the intervention, statistically significant differences (p < 0.000 were found in relation to the nutritional status of all the students evaluated, regardless of their sex. In reference to the adoption of healthy habits after the intervention, statistical significant differences were observed in the Krece Plus test (p < 0.000 and in the practice of physical exercise (p = 0.006. In the case of sedentary leisure activities, there was also a statistically significant reduction (p < 0.000 in the number of hours spent watching television for both male and female subjects. Conclusion: The results of this study show the effectiveness of the contents, activities, and duration of this health education intervention to encourage the subjects to modify their dietary and exercise habits.

We tested a dual-process model based on behavioral and emotional regulation constructs, which posits that good self-control and poor regulation make independent contributions and have different types of pathways to outcomes. The utility of the model for predicting substance use was tested in two diverse populations of younger adolescents. A survey was administered in classrooms to middle-school students in Westchester County, New York (N = 601) and Honolulu, Hawaii (N = 881). The New York sample was 8% African American, 5% Asian American, 47% Caucasian, 31% Hispanic, and 9% other ethnicity. The Hawaii sample was 21% Asian American, 8% Caucasian, 26% Native Hawaiian/Pacific Islander, 34% Filipino, and 10% other ethnicity. Structural equation modeling analyses tested pathways from the four regulation variables through six hypothesized mediators to a criterion construct of substance use (tobacco, alcohol, and marijuana). Results were replicated across samples and were consistent with prediction. Unique contributions were found for good self-control and poor regulation, including both behavioral and emotional aspects. Good self-control had an inverse effect on substance use primarily through relations to higher levels of protective factors (e.g., academic competence). Poor regulation independently had a risk-promoting effect on substance use through relations to higher levels of risk factors (e.g., negative life events). Two field studies showed the dual-process model is robust across different populations. Substance prevention programs should consider approaches for enhancing good self-control as well as procedures for reducing poor regulation and minimizing its impact. Extensions to health behaviors including dietary intake and physical activity are discussed. PsycINFO Database Record (c) 2013 APA, all rights reserved.
Full Text Available Considering the fact that most of the elderly people wish to rest in their home for as long as possible, we have asked ourselves why some choose to move in a retirement hostel at their free will. To answer this question, 32 semi-structured interviews were recorded among elderly people living in the region Centre, France. The cluster analysis of the obtained answers reveals four types of profiles corresponding to people for whom entering such an institution seems to be a stage in life for which one has to prepare and be able to keep control of.
Full Text Available Enuresis (9% at age 9.5 negatively affects children's psychosocial status. Clinically-diagnosed enuresis (2% at the age is associated with hyperactivity-inattention, and common neural bases have been postulated to underlie this association. It is, however, unclear whether this association is applicable to enuresis overall among the general population of early adolescents when considered comorbid behavioral problems. We aimed to examine whether enuresis correlates with hyperactivity-inattention after controlling for the effects of other behavioral problems.Participants were 4,478 children (mean age 10.2 ± 0.3 years old and their parents from the Tokyo Early Adolescence Survey (T-EAS, a population-representative cross-sectional study conducted in Tokyo, Japan conducted from 2012 to 2015. Children's enuresis and behavioral problems, including hyperactivity-inattention (as measured by the Strength and Difficulties Questionnaire, were examined using parent-reporting questionnaires. Multivariate linear regression was used to explore whether enuresis predicts hyperactivity-inattention.The hyperactivity-inattention score was significantly higher in the enuretic group than the non-enuretic group (enuretic: M (SD = 3.8 (2.3, non-enuretic: M (SD = 3.0 (2.1, Hedge's g = 0.39, p < .001. This association remained significant even after controlling for other behavioral problems and including sex, age, intelligence quotient (IQ, low birth weight and parents' education (β = .054 [95% CI: .028-.080], p < .001.Enuresis was independently associated with hyperactivity-inattention in early adolescents among general population even when other behavioral problems were considered. These results suggest that, as with clinically-diagnosed cases, enuresis may predict need for screening and psychosocial support for hyperactivity-inattention.

Associations between documented sun-exposure, exercise patterns and fish and supplement intake and 25-hydroxyvitamin D (25OHD) and parathyroid hormone (PTH) were investigated in a random household survey of Macau residents (aged 18-93). Blood samples (566) taken in summer were analyzed for 25OHD and PTH. In this Chinese population, 55% were deficient (25OHD Body Mass Index (β=0.07) and Ca supplement intake (β=-0.06). In this Macau population less documented sun exposure, fish and Ca supplement intake and exercise were associated with lower 25OHD levels, especially in the younger population, along with the interesting finding that more sitting was associated with both lower 25OHD and high PTH blood levels. In conclusion, unlike findings from Caucasian populations, younger participants were significantly more vitamin D deficient, in particular highly educated single females. This may indicate the desire of young females to be pale and avoid the sun. There are also big differences in lifestyle between the older generation and the younger, in particular with respect to sun exposure and PA. This article is part of a Special Issue entitled '17th Vitamin D Workshop'.

With a view to developing a brief screening instrument for autism symptoms in a general population of adolescents, seven items from the Asperger syndrome (and high-functioning autism) diagnostic interview were adapted for use as self-report in an online questionnaire for youths aged 16-19 years (N=10,220). The selected items target lack of social understanding (4 items) and rigid and repetitive behavior and interests (RRBI; 3 items). Factor analyses were performed, and the seven items were also validated against self-reported ASD diagnosis. Best statistical model fit was found for a bifactor model with one general factor and two domain specific factors tied to social difficulties and RRBI. Both the general and the domain specific factors were associated with self-reported ASD diagnoses. The scale (referred to as the Autism Symptom SElf-ReporT for Adolescents and Adults--ASSERT) had good screening properties with a receiver operating curve-area under the curve (ROC-AUC) of 0.87 and a diagnostic odds ratio (DOR) of 15.8. Applying a modified scoring of the scale further improved the screening properties leading to a ROC-AUC of 0.89 and a DOR of 24.9. The ASSERT holds promise as a brief self-report screen for autism symptoms in adolescents, and further studies should explore its usefulness for adults.

Full Text Available Background. The current study examined parental factors related to risk of adolescent obesity within the context of a family systems framework. Methods. Seventy predominantly African American, low-income caregiver-adolescent dyads participated in the study. Validated measures of parental perceived child risk for development of type 2 diabetes mellitus, parental limit setting for sedentary behavior, and parental nurturance were evaluated as predictors of adolescent body mass index. Results. In this cross-sectional study, multiple linear regression demonstrated that parents of adolescents with higher zBMI reported worrying more about their child's risk of developing type 2 diabetes mellitus. Parent limit setting was also a significant predictor of adolescent zBMI. Contrary to expectations, higher levels of nurturance were associated with higher adolescent zBMI. Post hoc analyses revealed a trend towards a significant interaction between nurturance and limit setting, such that high levels of both parental nurturance and limit setting were associated with lower adolescent zBMI. Conclusions. Current findings suggest the importance of authoritative parenting and monitoring of adolescent health behaviors in the treatment of obesity.

Theory holds that income inequality may harm adolescent mental health by reducing social capital within neighborhood communities. However, research on this topic has been very limited. We use multilevel data on 102 public schools and 5958 adolescents in Iceland (15 and 16 years old) to examine whether income inequality within neighborhoods is associated with emotional distress in adolescents. Moreover, we test whether indicators of social capital, including social trust and embeddedness in neighborhood social networks, mediate this contextual effect. The findings show that neighborhood income inequality positively influences emotional distress of individual adolescents, net of their personal household situations and social relations. However, although the indicators of social capital negatively influence emotional distress, they do not mediate the contextual effect of neighborhood income inequality. The study illustrates the role of economic disparities in adolescent mental health, but calls for more research on the underlying social and social-psychological mechanisms.

In Southeast Asia, swamp eels (Synbranchidae: Monopterus spp.) are a common source of human gnathostomiasis, a foodborne zoonosis caused by advanced third-stage larvae (AL3) of Gnathostoma spp. nematodes. Live Asian swamp eels are imported to US ethnic food markets, and wild populations exist in several states. To determine whether these eels are infected, we examined 47 eels from markets and 67 wild-caught specimens. Nematodes were identified by morphologic features and ribosomal intergenic transcribed spacer–2 gene sequencing. Thirteen (27.7%) M. cuchia eels from markets were infected with 36 live G. spinigerum AL3: 21 (58.3%) in liver; 7 (19.4%) in muscle; 5 (13.8%) in gastrointestinal tract, and 3 (8.3%) in kidneys. Three (4.5%) wild-caught M. albus eels were infected with 5 G. turgidum AL3 in muscle, and 1 G. lamothei AL3 was found in a kidney (both North American spp.). Imported live eels are a potential source of human gnathostomiasis in the United States.

This study analyzed differences in healthy life expectancy in the elderly based on three health dimensions in Brazil from 1998 to 2008: disability-free life expectancy, healthy life expectancy based on self-rated health, and chronic disease-free life expectancy. The Sullivan method was used, combining life tables from the Brazilian Institute of Geography and Statistics (IBGE) and interval estimates of the prevalence of functional disability, self-rated health, and chronic diseases according to the Brazilian National Household Sample Survey (PNAD, 1998 and 2008). Besides the increase in life expectancy, the study showed significant and similar increases in disability-free life expectancy and healthy life expectancy based on self-rated health at almost all ages. Women had higher life expectancies than men, but expected to live longer with poor health, regardless of the indicator used to measure health. Although the studies measured health differently (making comparisons difficult), women showed a consistent disadvantage in healthy life expectancy.

The effect of distance from a heavy metal pollution source on the soil nematode community (trophic structure, sex structure, and taxa composition) was investigated along a 15-km transect originating at the Almalyk Industrial Complex, Uzbekistan (pollution source). The soil nematode community was exposed to heavy metal influence both directly and through soil properties changes. Pollution effect on the density and biomass of soil free-living nematodes was found to be highest at pollution source, with fungivores and plant parasites dominating at the upper and deeper soil layers next to the pollution source. These groups decreased along the transect, yielding domination to bacteria- and fungi-feeders. The sex ratio of nematode communities was found to be dependent on heavy metal pollution levels, with the juveniles being the most sensitive nematode group. The Maturity and modified Maturity Indices, reflecting the degree of disturbance of the soil ecosystem, were found to be the most sensitive indices.

Background: Prevalence of musculoskeletal pain among adolescents is high, and pain in adolescence increases the risk of chronic pain in adulthood. Studies have shown conflicting evidence regarding associations between physical activity and musculoskeletal pain, and few have evaluated the potential impact of sport participation on musculoskeletal pain in adolescent population samples. Purpose: To examine the associations between physical activity level, sport participation, and musculoskeletal pain in the neck and shoulders, low back, and lower extremities in a population-based sample of adolescents. Study Design: Cross-sectional study; Level of evidence 4. Methods: Data from the Nord-Trøndelag Health Study (Young-HUNT3) were used. All 10,464 adolescents in the Nord-Trøndelag county of Norway were invited, of whom 74% participated. Participants were asked how often they had experienced pain, unrelated to any known disease or acute injury, in the neck and shoulders, low back, and lower extremities in the past 3 months. The associations between (1) physical activity level (low [reference], medium or high) or (2) sport participation (weekly compared with no/infrequent participation) and pain were evaluated using logistic regression analyses, stratified by sex, and adjusted for age, socioeconomic status, and psychological distress. Results: The analyses included 7596 adolescents (mean age, 15.8 years; SD, 1.7). Neck and shoulder pain was most prevalent (17%). A moderate level of physical activity was associated with reduced odds of neck and shoulder pain (OR = 0.79 [95% CI, 0.66-0.94]) and low back pain (OR = 0.75 [95% CI, 0.62-0.91]), whereas a high level of activity increased the odds of lower extremity pain (OR = 1.60 [95% CI, 1.29-1.99]). Participation in endurance sports was associated with lower odds of neck and shoulder pain (OR = 0.79 [95% CI, 0.68-0.92]) and low back pain (OR = 0.77 [95% CI, 0.65-0.92]), especially among girls.

Full Text Available Background. Sleep duration, either short or long, has been associated with diseases such as obesity, type-2 diabetes and cardiovascular diseases. Characterizing the prevalence and patterns of sleep duration at the population-level, especially in resource-constrained settings, will provide informative evidence on a potentially modifiable risk factor. The aim of this study was to explore the patterns of sleep duration in the Peruvian adult and adolescent population, together with its socio-demographic profile.Material and Methods. A total of 12,424 subjects, mean age 35.8 years (SD ±17.7, 50.6% males, were included in the analysis. This is a cross-sectional study, secondary analysis of the Use of Time National Survey conducted in 2010. We used weighted means and proportions to describe sleep duration according to socio-demographic variables (area and region; sex; age; education attainment; asset index; martial and job status. We used Poisson regressions, taking into account the multistage sampling design of the survey, to calculate crude and adjusted prevalence ratios (PR and 95% confidence intervals (95% CI. Main outcomes were short- (<6 h and long-sleep duration (≥ 9 h.Results. On average, Peruvians slept 7.7 h (95% CI [7.4–8.0] on weekdays and 8.0 h (95% CI [7.8–8.1] during weekends. The proportions of short- and long-sleep, during weekdays, were 4.3% (95% CI [2.9%–6.3%] and 22.4% (95% CI [14.9%–32.1%], respectively. Regarding urban and rural areas, a much higher proportion of short-sleep was observed in the former (92.0% vs. 8.0%; both for weekdays and weekends. On the multivariable analysis, compared to regular-sleepers (≥ 6 to <9 h, short-sleepers were twice more likely to be older and to have higher educational status, and 50% more likely to be currently employed. Similarly, relative to regular-sleep, long-sleepers were more likely to have a lower socioeconomic status as per educational attainment.Conclusions. In this

Full Text Available Sequence based typing was used to identify human leukocyte antigen (HLA-A, -B, -C, -DRB1 alleles in 1,064 recruited volunteers in the Republic of Bashkortostan of the Russian Federation for unrelated hematopoietic stem cell registry. During the carried out research two new alleles were identified in the studied population; one was registered in the WHO Nomenclature Committee for Factors of the HLA System, the other one was submitted for registration. In this population 17 HLA-A, 29 – HLA-B, 13 – HLA-C, 13 – HLA-DRB1 groups of alleles were selected. Allele frequencies of more than 10% included HLA-A*02 (29.37%, 24 (12.92%, 01 (11.84%, 03 (11.61%, HLA-B*35 (11.51%, 07 (10.76%, HLA-C*07 (22.56%, 06 (15.51%, 04 (13.06%, 03 (10.43%, 12 (10.24%, HLA-DRB1*07 (17.25%, 15 (12.73%, 13 (11.98%, 01 (11.84%, 04 (11.61%. 711 HLA-A-B-C-DRB1 four-locus haplotypes were determined using the software Arlequin v.3.1. The most frequently observed four-locus haplotypes were A*02-B*13-C*06-DRB1*07, A*03-B*35-C*07-DRB1*15, A*02- B*07-C*07-DRB1*15 with frequencies of 2.89%, 2.18% and 1.93%, respectively. The distribution of alleles and haplotype analysis allowed comparing the populations of the Republic of Bashkortostan with the other Russian populations.

Chilean aboriginal populations (Mapuche) predominantly live in the region of Araucanía, in the southern part of the country. Their cardiovascular risk factors have not been systematically assessed. To study the prevalence of cardiovascular risk factors in the Mapuche population. Blood pressure, weight, height, dietary habits, fasting serum total cholesterol, HDL cholesterol and triglycerides were measured in 1.948 adults living in 28 Mapuche communities. Thirteen percent of males and 16% of females had high blood pressure. Body mass index was 25.5 kg/m2 in males and 28.1 kg/m2 in females. Forty five percent of women and 24% of men were classified as obese. Mean serum total cholesterol was 186.7 +/- 9.6 mg/dl, HDL cholesterol was 58.7 +/- 30.7 mg/dl, total cholesterol/HDL cholesterol was 3.4 +/- 2 and triglycerides were 155.2 +/- 91.2 mg/dl. Twenty eight percent of males and 9.6% of females smoked. Mapuche individuals have higher levels of HDL cholesterol a better total cholesterol/HDL cholesterol ratio and lower frequency of smoking than non aboriginal Chileans subjects.
Full Text Available The aim of this study was to present the general situation of populations of European post-communist countries 25 years after the collapse of communism in Europe. The study consists of two parts. The first one briefly discusses the processes that led to a significant diversification in the social, economic and political situations of the populations of the studied countries. In the second part the diversity of this situation is shown (using: the Legatum Prosperity Index, the Social Progress Index, and the Human Development Index. It was found that the best situations exist in the countries which quickly and effectively implemented reforms, and whether they were independent states, or parts of larger states, under communism is of secondary importance. It is symptomatic that these are countries situated in the north-western part of the area under consideration, which corresponds to the current situation in the EU-15, where the countries located in the south (the so-called PIGS have poor economic and partly social situations than those in the north. Furthermore, it was found that the situation with the population of Russia is worse than in many countries which were previously under the occupation of the USSR or were dependent on the authorities in Moscow.

The Druze population is a small-sized Near Eastern genetic isolate with high rates of consanguineous marriages. The present study aimed at investigating prevalence, pattern and distribution of hypodontia in the permanent dentition, excluding wisdom teeth, amongst this population. Panoramic radiographs, dental casts, and anamnestic records of 85 un-admixed Druze schoolchildren (45 males, 40 females; age range=14-18 years, mean age=16 years, SD=0.5 years) were examined for evidence of hypodontia. Those with any type of facial clefts or craniofacial syndromes were excluded. Hypodontia prevalence was 11.8% (11.1% for males, 12.5% for females) with no statistically significant difference between sexes. The average number of missing teeth per child was 1.4 (1.2 for males, 1.6 for females). The majority (90%) of affected individuals exhibited minor hypodontia (one or two teeth missing). The most commonly missing teeth were upper lateral incisors and canines, followed by lower and upper second premolars. Asymmetrical hypodontia was more prevalent. Maxillary, left side, and anterior segment predominance were observed. The distinct features of hypodontia among the Druze population are the relatively high prevalence of minor hypodontia, and the upper lateral incisors and canines being the most commonly missing teeth.

A field study was designed to examine the effect of desert shrubs on the dynamics of free-living amoebae in arid soil. Soil samples from 0- to 50-cm depths were collected at 10-cm intervals in each of the four seasons. The vertical distributions of the four main morphological types of amoebae, grouped according to their mobility, and of small flagellate populations were measured under the canopies of Hammada scoparia and Atriplex halimus, shrubs belonging to the chloride-absorbing xerohalophytes. The result obtained from the field study demonstrated that the total number of protozoa was significantly higher during the wet seasons (winter and spring) than during the dry seasons. The protozoan population was more diverse under the canopy of H. scoparia during the wet seasons, reaching 8,000 individuals per 1 g of dry soil, whereas during the dry seasons, the populations were higher under the canopy of A. halimus, with a mean of 250 individuals. The protozoan population in the deeper layers (40 to 50 cm) was found to be as active as that in the upper layers, demonstrating that, in the desert, soil columns below 20 cm are fertile and worth studying. The type 1 amoebae (e.g., Acanthamoeba and Filamoeba spp.) were the most abundant throughout the study period, and their numbers were significantly higher than those of the other amoeba types.

To examine the relationship between the Big-Five personality model and autodestructive behavior symptoms, namely Autodestructiveness and Suicidal Depression in two groups of participants: clinical and non-clinical adolescents. Two groups of participants, clinical (adolescents with diagnosis of psychiatric disorder based on clinical impression and according to valid diagnostic criteria, N=92) and non-clinical (high-school students, N=87), completed two sets of questionnaires: the Autodestructiveness Scale which provided data on Autodestructiveness and Suicidal Depression, and the International Personality Item Pool (IPIP), which provided data on the Big -Five personality dimensions. Clinical group showed significantly higher values on the Autodestructiveness scale in general, as well as on Suicidal Depression, Aggressiveness, and Borderline subscales than the non-clinical group. Some of the dimensions of the Big-Five personality model, ie, Emotional Stability, Conscientiousness, and Agreeableness showed significant relationship (hierarchical regression analyses, P values for β coefficients from 0.000 to 0.021) with Autodestructiveness and Suicidal Depression, even after controlling for the sex and group effects or, when analyzing Suicidal Depression, after controlling the effect of other subscales. The results indicate that dimensions of the Big-Five model are important when evaluating adolescent psychiatric patients and adolescents from general population at risk of self-destructive behavior.
Full Text Available BACKGROUND: It has been argued that the association between job strain and health could be confounded by early life exposures, and studies have shown early adversity to increase individual vulnerability to later stress. We therefore investigated if early life exposure to adversity increases the individual's physiological vulnerability job strain in adulthood. METHODOLOGY/PRINCIPAL FINDINGS: In a population-based cohort (343 women and 330 men, 83% of the eligible participants, we examined the association between on the one hand exposure to adversity in adolescence, measured at age 16, and job strain measured at age 43, and on the other hand allostatic load at age 43. Adversity was operationalised as an index comprising residential mobility and crowding, parental loss, parental unemployment, and parental physical and mental illness (including substance abuse. Allostatic load summarised body fat, blood pressure, inflammatory markers, glucose, blood lipids, and cortisol regulation. There was an interaction between adversity in adolescence and job strain (B = 0.09, 95% CI 0.02 to 0.16 after adjustment for socioeconomic status, particularly psychological demands, indicating that job strain was associated with increased allostatic load only among participants with adversity in adolescence. Job strain was associated with lower allostatic load in men (β = -0.20, 95% CI -0.35 to -0.06. CONCLUSIONS/SIGNIFICANCE: Exposure to adversity in adolescence was associated with increased levels of biological stress among those reporting job strain in mid-life, indicating increased vulnerability to environmental stressors.
Full Text Available Abstract Background In 1988 the World Health Assembly adopted the goal to eradicate poliomyelitis by routine immunization using Oral Polio Vaccine (OPV. On 21 June 2002 the WHO European Region was declared polio-free. In 2008 poliomyelitis is still endemic in 4 countries (Nigeria, India, Pakistan, and Afghanistan, where 1201 new cases were registered in 2007; 107 sporadic cases were also notified in countries where poliovirus is not endemic. The aim of this work was to verify the level of antipoliomyelitis immunity status in children and adolescents in the Apulia region (south of Italy, which may be considered a border region due to its position. Methods 704 blood specimens from a convenience sample were collected in six laboratories. The age of subjects enrolled was 0–15 years. The immunity against poliomyelitis was evaluated by neutralizing antibody titration in tissue culture microplates. Results Seropositivity (neutralising antibodies titre ≥ 8 for polioviruses 1, 2 and 3 was detected in 100%, 99.8% and 99.4% of collected sera. Antibody titres were not lower in subjects who received either four doses of inactivated polio vaccine (IPV or a sequential schedule consisting of two doses of IPV and two of oral polio vaccine than in subjects who received four doses of OPV. Conclusion These results confirmed current data of vaccine coverage for poliomyelitis: during the last ten years in Apulia, the coverage in 24 months old children was more than 90%. The high level of immunization found confirms the effectiveness both of the sequential schedule IPV-OPV and of the schedule all-IPV. Apulia region has to face daily arrivals of refugees and remains subject to the risk of the importation of poliovirus from endemic areas. Surveys aimed at determining anti-polio immunity in subpopulations as well as in the general population should be carried out.
Full Text Available BACKGROUND: A rapid rise in the number of captive African elephants (Loxodonta africana used in the tourism industry in southern Africa and orphaned elephants in human care has led to concerns about their long-term management, particularly males. One solution is to release them into the wild at adolescence, when young males naturally leave their herd. However, this raises significant welfare concerns: little is known about how well released elephants integrate into wild populations and whether they pose a greater threat to humans than wild elephants. We document the release of three captive-raised adolescent male African elephants in the Okavango Delta, Botswana. METHODOLOGY/PRINCIPAL FINDINGS: Despite having been part of a herd of working elephants for at least eight years, the three males progressively integrated into the complex fission-fusion society of wild bull elephants. In the three years following release, they showed no tendency to be closer to human habitation, and there were no significant differences between wild and captive-raised adolescent males in the total number of social interactions, size of ranges and habitat use. However, the captive-raised elephants sparred less and vocalised more, and spent more time alone and in smaller social groups. Thereafter the released elephants continued to expand their ranges and interact with both mixed-sex herds and males. One male was shot by farmers 94 months after release, along with ten wild elephants, on a ranch outside the protected area. CONCLUSIONS/SIGNIFICANCE: We show that captive-raised adolescent male elephants can integrate into a wild population. Long-term studies are required to determine the longevity, breeding success, and eventual fate of released male elephants, but we identified no significant short-term welfare problems for the released elephants or recipient population. Release of captive-raised mammals with complex social systems is a husbandry option that should be

To determine the serum concentrations of aflatoxin B1 (AFB1), aflatoxin B2 (AFB2), aflatoxin G1 (AFG1) and aflatoxin G2 (AFG2) in the healthy adult population living in both the Black Sea and Mediterranean regions of Turkey and to investigate the regional, seasonal and gender variability in aflatoxins (AF) exposure in these regions. Serum AFB1, AFB2, AFG1 and AFG2 concentrations were analysed by HPLC. Settings In total, four hundred and eighty-four serum samples were analysed. Four hundred and eighty-four healthy adult volunteers living in rural areas of the Black Sea and Mediterranean regions of Turkey were studied. The mean serum concentration of total AF in the Black Sea region was 1·33 ppb (min-max 0·15-3·38 ppb) and 0·90 ppb (min-max 0·18-2·48 ppb) for summer and winter, respectively. In the Mediterranean region, the mean serum concentration of total AF was determined as 0·55 ppb (range 0·04-1·72 ppb) for summer and 0·45 ppb (range 0·12-1·43 ppb) for winter. The total AF concentrations in serum samples were statistically higher in summer compared with winter for the two regions. The differences between the regions were statistically significant concerning all samples, with higher total AF concentrations in the Black Sea region. The overall results suggest that the Turkish population living in these two regions is continuously exposed to AF, particularly in the summer, and that mycotoxin contamination in food should be monitored routinely for food safety and human health.

Anorexia nervosa in adolescence has been increasingly documented in numerous quantitative and qualitative studies. Qualitative research, which focuses on subjective experience, is a well-established method to deepen our understanding and provide new insights about specific diseases. We conducted a metasynthesis of qualitative studies to explore how anorexia nervosa is experienced by adolescents, their families, and the health professionals who provide care for them and to compare their perspectives. Five databases (Medline, PsycINFO, CINHAL, EMBASE, SSCI; 1990-2015) were systematically searched for qualitative studies reporting participants' views about anorexia nervosa. Article quality was assessed with the Critical Appraisal Skills Program (CASP). We used thematic synthesis to examine and summarize the topics found in the articles selected and develop their central themes. We included 30 articles from seven different countries. Two domains of experience were inductively developed from the analysis: (1) constructs and beliefs about etiological theories of anorexia nervosa, and (2) the experience of the disease from the points of view of adolescents, parents, and healthcare providers. We found important disparities between the three stakeholders. The adolescents underlined the psychological and emotional aspects of their experience, while the visible state of these patients' bodies impeded the work of the professionals. These difficulties shed new light on the stakes of treatment of anorexia nervosa in adolescence, which must integrate both its psychological and physical components. Copyright Â© 2016 Elsevier Ltd.

The current study aimed to compare the prevalence, stability, and psychosocial correlates of DSM-IV-TR and DSM-5 eating disorders, in a population-based sample of male and female adolescents followed prospectively from 14 to 20 years of age. Participants (N = 1,383; 49% male) were drawn from the Western Australian Pregnancy Cohort (Raine) Study, a prospective, population-based cohort study that has followed participants from prebirth to young adulthood. Detailed self-report questionnaires were used to assess eating disorder symptoms when participants were aged 14, 17, and 20 years. Comparisons between DSM-IV-TR and DSM-5 were conducted using McNemar chi-square tests and Fisher's exact tests. Changes in eating disorder prevalence over time were considered using generalized estimating equations. Eating disorder prevalence rates were significantly greater when using DSM-5 than DSM-IV-TR criteria, at all time points for females and at age 17 only for males. "Unspecified"/"other" eating disorder diagnoses were significantly less common when applying DSM-5 than DSM-IV-TR criteria, but still formed 15% to 30% of the DSM-5 cases. Diagnostic stability was low for all disorders, and DSM-5 binge eating disorder or purging disorder in early adolescence predicted DSM-5 bulimia nervosa in later adolescence. Cross-over from binge eating disorder to bulimia nervosa was particularly high. Regardless of the diagnostic classification system used, all eating disorder diagnoses were associated with depressive symptoms and poor mental health quality of life. These results provide further support for the clinical utility of DSM-5 eating disorder criteria, and for the significance of binge eating disorder and purging disorder.

Children and adolescents living with HIV have low bone mass for age. There are reliable and accurate methods for evaluation of bone mass, however, alternative methods are necessary, especially, for application in limited-resource scenarios. Anthropometry is a noninvasive and low cost method that can predict bone mass in healthy youths. The aim of the study was to develop predictive equations for bone mineral content and bone mineral density in children and adolescents living with HIV based on anthropometric variables. Forty-eight children and adolescents of both sexes (24 females) from 7 to 17 years, living in greater Florianopolis area, Santa Catarina, Brazil, who were under clinical follow-up at "Hospital Infantil Joana de Gusmão", participated in the study. Dual-energy X-ray absorptiometry was used to evaluate whole-body bone mineral content (BMC) and areal bone mineral density (aBMD). Height, body weight, bone diameters, arm circumference, and triceps skinfold were measured and the body mass index and arm muscle area were calculated. Multiple regression models were fitted to predict BMC and aBMD, using backward selection (p ≥ 0.05). Two predictive models with high R(2) values (84%-94%) were developed. Model 1 to estimate aBMD [Y = -0.1450124 + (height × 0.0033807) + (age × 0.0146381) + (body mass index × 0.0158838) + (skin color × 0.0421068)], and model 2 to estimate BMC [Y = 1095.1 + (body weight × 45.66973) + (age × 31.36516) + (arm circumference × -53.27204) + (femoral diameter × -9.594018)].The predictive models using anthropometry provided reliable estimates and can be useful to monitor aBMD and BMC in children and adolescents living with human immunodeficiency virus where limited resources are available.
Full Text Available BACKGROUND: There is need for locally-derived age-specific clinical laboratory reference ranges of healthy Africans in sub-Saharan Africa. Reference values from North American and European populations are being used for African subjects despite previous studies showing significant differences. Our aim was to establish clinical laboratory reference values for African adolescents and young adults that can be used in clinical trials and for patient management. METHODS AND FINDINGS: A panel of 298, HIV-seronegative individuals aged 13-34 years was randomly selected from participants in two population-based cross-sectional surveys assessing HIV prevalence and other sexually transmitted infections in western Kenya. The adolescent (<18 years-to-adults (≥ 18 years ratio and the male-to-female ratio was 1∶1. Median and 95% reference ranges were calculated for immunohematological and biochemistry values. Compared with U.S-derived reference ranges, we detected lower hemoglobin (HB, hematocrit (HCT, red blood cells (RBC, mean corpuscular volume (MCV, neutrophil, glucose, and blood urea nitrogen values but elevated eosinophil and total bilirubin values. Significant gender variation was observed in hematological parameters in addition to T-bilirubin and creatinine indices in all age groups, AST in the younger and neutrophil, platelet and CD4 indices among the older age group. Age variation was also observed, mainly in hematological parameters among males. Applying U.S. NIH Division of AIDS (DAIDS toxicity grading to our results, 40% of otherwise healthy study participants were classified as having an abnormal laboratory parameter (grade 1-4 which would exclude them from participating in clinical trials. CONCLUSION: Hematological and biochemistry reference values from African population differ from those derived from a North American population, showing the need to develop region-specific reference values. Our data also show variations in hematological

The appropriateness of applying risk coefficients calculated from short-term exposures at high doses for the assessment of radiation effects at low doses is currently much debated. The problem can be resolved on the basis of the data obtained from a long-term follow-up of the population exposed in the early 1950s when discharges of radioactive wastes from a radiochemical plant into the Techa River (southern Urals) occurred. This paper discusses the results of an analysis of cancer mortality during the period 1950-82. 10 refs., 5 figs., 8 tabs.

Risk assessments for human health have been conducted for municipal solid waste incinerators (MSWIs) in many western countries, whereas only a few risk assessments have been performed for MSWIs in developing countries such as China where the use of waste incineration is increasing rapidly. To assess the mercury exposure risks of a population living near the largest MSWI in South China, we combined internal exposure and external exposure assessment with an individual-specific questionnaire. The mercury concentrations in air, soil, and locally collected food around the MSWI were assessed. The total mercury (T-Hg) and methylmercury (MeHg) of 447 blood samples from a control group, residential exposure group, and MSWI workers were measured. The internal and external exposures of the subject population were analyzed. Significant difference in MeHg concentrations was observed between the control group and the exposed group, between the control group and the MSWI workers, and between the exposed group and the MSWI workers (median levels: 0.70 μg/L, 0.81 μg/L, and 1.02 μg/L for the control group, exposed group, and MSWI workers, respectively). The MeHg/T-Hg ratio was 0.51 ± 0.19, 0.59 ± 0.17 and 0.58 ± 0.25, respectively. Multiple linear regression analysis indicated that MeHg concentrations were positively correlated with the gaseous mercury in the air. Combining internal and external exposure assessment showed that the direct contribution of MSWI emissions was minor compared with the dietary contribution. The external and internal exposures were well matched with each other. This study also suggested that an integrated method combining internal and external exposure assessment with an individual-specific questionnaire is feasible to assess the risks for a population living near a MSWI.

To determine the effect of agricultural management on the dynamics and functional diversity of soil nematode communities in a carrot field at Kibbutz Ramat Hakovesh, Israel, soil samples from 0-10 cm and 10-20 cm depths were collected during the growing season of carrot. Indices were used to compare and assess the response of soil free-living nematode communities to agricultural management. Eighteen nematode families and 20 genera were observed during the growing period, with Cephalobus, Rhabditidae, Aphelenchus, Tylenchus, and Dorylaimus being the dominant genera/families.During the planting, mid-season and post-harvest periods the total number of nematodes at both depths was significantly lower (P ＜ 0.01) in the carrot treatment than in the control plots, while during the harvest period at both depths total nematodes and bacterivores were significantly higher in the treatment plots (P ＜ 0.01). The values of the maturity index (MI) at both depths were found to be significantly lower in the treatment plots than in the control plots during the pre-planting period (P ＜ 0.05). Overall, WI, MI and PPI were found to be more sensitive indicators than other ecological indices for assessing the response of nematode communities to agricultural management in a Mediterranean agroecosystem.
For any system, whether physical or non-physical, knowledge of the form and strength of inter-individual interactions is a key-information. In an approach based on statistical physics one needs to know the interaction Hamiltonian. For non-physical systems, based on qualitative arguments similar to those used in physical chemistry, interaction strength gives useful clues about the macroscopic properties of the system. Even though our ultimate objective is the understanding of social phenomena, we found that systems composed of insects (or other living organisms) are of great convenience for investigating group effects. In this paper we show how to design experiments that enable us to estimate the strength of interaction in groups of insects. By repeating the same experiments with increasing numbers of insects, ranging from less than 10 to several hundreds, one is able to explore key-properties of the interaction. The data turn out to be consistent with a global correlation that is independent of distance (at l...

Adolescent depression is associated with a range of interpersonal adversities. We hypothesized that depressed adolescents are at subsequent increased risk of problems related to intimate relationships and childbearing in adulthood, and used longitudinal data to examine this. A population-based investigation of depression in 16 to 17 year olds was followed up after 15 years, at around the age of 30 years. Comparisons were made between adolescents with depression (n = 361, 78% females) and non-depressed peers (n = 248, 77% females). Data from both national registers and personal interviews were used. At follow-up, the former depressed and non-depressed adolescents had become parents to a similar extent. The former depressed females were more likely than the non-depressed females to report abortion, miscarriage, intimate partner violence and sexually transmitted disease. They also reported a higher number of intimate relationships and were more likely to have divorced and to be registered as single mothers. Depressed females with a comorbid disruptive disorder had a particularly poor outcome. In the depressed females without a disruptive disorder, only those who subsequently had recurrent depressions in adulthood were at increased risk of poor outcome. There was no indication that the formerly depressed males were at increased risk of subsequent problems related to intimate relationships. Females with adolescent depression subsequently have problems related to intimate relationships and childbearing. Disruptive disorders and recurrence of depression appear to be instrumental in this association. Attention should be given to intimate relationship problems and sexual and reproductive health issues in young women with depression.

Full Text Available BACKGROUND: Hoarding Disorder (HD is often assumed to be an 'old age' problem, but many individuals diagnosed with HD retrospectively report first experiencing symptoms in childhood or adolescence. We examined the prevalence, comorbidity and etiology of hoarding symptoms in adolescence. METHODS: To determine the presence of clinically significant hoarding symptoms, a population-based sample of 15-year old twins (N = 3,974 completed the Hoarding Rating Scale-Self Report. Co-occurring Obsessive Compulsive Disorder (OCD, Autism Spectrum Disorders (ASD and Attention Deficit Hyperactivity Disorder (ADHD were estimated from parental report. Model-fitting analyses divided hoarding symptom scores into additive genetic, shared, and non-shared environmental effects. RESULTS: The prevalence of clinically significant hoarding symptoms was 2% (95% CI 1.6-2.5%, with a significantly higher prevalence in girls than boys. Exclusion of the clutter criterion (as adolescents do not have control over their environment increased the prevalence rate to 3.7% (95% CI 3.1-4.3%. Excessive acquisition was reported by 30-40% among those with clinically significant hoarding symptoms. The prevalence of co-occurring OCD (2.9%, ASD (2.9% and ADHD (10.0% was comparable in hoarding and non-hoarding teenagers. Model-fitting analyses suggested that, in boys, additive genetic (32%; 95% CI 13-44% and non-shared environmental effects accounted for most of the variance. In contrast, among girls, shared and non-shared environmental effects explained most of the variance, while additive genetic factors played a negligible role. CONCLUSIONS: Hoarding symptoms are relatively prevalent in adolescents, particularly in girls, and cause distress and/or impairment. Hoarding was rarely associated with other common neurodevelopmental disorders, supporting its DSM-5 status as an independent diagnosis. The relative importance of genetic and shared environmental factors for hoarding differed
Social intelligence is a construct that has shown promising practical applications, but its use in research and applied settings has been limited by definitional problems and the complexity of most existing measures of social intelligence. The goal of the present study was to adapt the Italian version [Gini & Iotti (2004) La Tromsø Social Intelligence Scale: Traduzione e adattamento alla popolazione Italiana. Italy: University of Padova.] of the Tromsø Social Intelligence Scale, TSIS [Silvera, Martinussen, & Dahl (2001). Scandinavian Journal of Psychology, 42, 313-319.] to the adolescent population (the sample comprised 320 Italian adolescents, 132 boys and 188 girls). Our analyses revealed the same factorial structure of the original scale and showed a good internal reliability. The items of the TSIS-IV were reasonably unbiased in terms of social desirability response bias.

The aim of this work is identify the contribution of individual factors, habits and life conditions in nutritional status. Material and methods: estimates of relative risk ratios are obtained from a multinomial logistic model using microdata from the National Survey of Risk Factors conducted in 2005 and 2009 in Argentinean‘ cities among adult population. Results: malnutrition is associated with constitutive and socioeconomic variables, while habits are also important in the obesity case. Discussion: both types of problems coexist in Argentine due to high heterogeneity in life styles, turning difficult the design of public interventions aimed to solve them. This complexity highlights the importance of a careful and specific multidimensional approach (medical, social, economical.

The aim of this study was to conduct a POP biomonitoring programme for children in high-risk areas. We evaluated 247 serum samples from children between the ages of 6 and 12years old from two zones in Mexico: (1) indigenous zones, which included Cuatlamayan (CUA), Tocoy (TOC), and Santa Maria Picula (SAM); and (2) industrial zones, which included Tercera Chica (TC), Industrial San Luis (IND) and Rincon de San Jose (SJR); Mundo Nuevo (MN); and Alpuyeca (ALP). Our results showed that α-endosulfan was similar to CUA, TOC, SAM, TC and MN (178.6-306.9ng/g lipid). β-Endosulfan levels were higher in ALP (901.5ng/g lipid), followed by CUA (139.9ng/g lipid) and TOC, SAM, TC and MN, which had similar levels (55.4-64.5ng/g lipid). For endosulfan sulfate, the ALP community had the highest concentration levels (1096.4ng/g lipid), whereas CUA and TOC (212.3 and 289ng/g lipid, respectively) had concentrations similar to those found in SAM and TC (99.5 and 119.1ng/g lipid, respectively). DDE levels were found in malaria-endemic areas of SAM, CUA and TOC (1782.2, 1358.3 and 57.0ng/g lipid), followed by MN (35.1ng/g lipid). HCB concentration levels were found to be higher in MN and SJR (691.8 and 575.4ng/g lipid, respectively), followed by CUA and TC (363.9 and 269.1ng/g lipid, respectively), with levels similar to those found in TOC and SAM (191.8 and 181.9ng/g lipid, respectively). Finally, PCB 101 concentration levels were found to be the highest in ALP (1032.7ng/g lipid), followed by similar levels of SJR and IND (567.5 and 327.3ng/g lipid, respectively) and TC and MN, with 109.1 and 144.5ng/g lipid, respectively. The evidence provided by this exploratory study indicates that the evaluation of the health risks posed to children living in contaminated areas is a high priority health issue.

Full Text Available Marijuana initiation during adolescence, and early adolescence in particular, is associated with adverse health consequences. Our study used 2005-2014 data from the annual, cross-sectional National Survey on Drug Use and Health to study the prevalence and correlates of marijuana initiation, use, and marijuana use disorder (MUD; abuse or dependence among 12- to 14-year olds living in civilian US households (n = 84 954. Examined correlates included age, sex, race/ethnicity, poverty status, metropolitan status, year of survey, depression, tobacco use, alcohol use, and fighting at school. Sex differences in the correlates of lifetime use and past year marijuana initiation were tested via interaction. Lifetime prevalence of marijuana use was 5.5%; 3.2% reported past year initiation. About 1 in 6 (16.8% past year initiates progressed to MUD within 12 months of first use. Although men had higher prevalence of lifetime use than women, past year initiation did not differ by sex. On examining the sex*race/ethnicity interaction effects, findings determined that non-Hispanic black and Hispanic men had higher prevalence estimates of ever using marijuana and incidence of past year initiation as compared with non-Hispanic white men; these race/ethnicity differences were not found among women. Identifying correlates of initiation and progression to MUD among young adolescents is critical to improve prevention and treatment program targets.

Almost all bacterial genomes contain DNA of viral origin, including functional prophages or degenerated phage elements. A frequent but often unnoted phenomenon is the spontaneous induction of prophage elements (SPI) even in the absence of an external stimulus. In this study, we have analyzed SPI of the large, degenerated prophage CGP3 (187 kbp), which is integrated into the genome of the Gram-positive Corynebacterium glutamicum ATCC 13032. Time-lapse fluorescence microscopy of fluorescent reporter strains grown in microfluidic chips revealed the sporadic induction of the SOS response as a prominent trigger of CGP3 SPI but also displayed a considerable fraction (∼30%) of RecA-independent SPI. Whereas approx. 20% of SOS-induced cells recovered from this stress and resumed growth, the spontaneous induction of CGP3 always led to a stop of growth and likely cell death. A carbon source starvation experiment clearly emphasized that SPI only occurs in actively proliferating cells, whereas sporadic SOS induction was still observed in resting cells. These data highlight the impact of sporadic DNA damage on the activity of prophage elements and provide a time-resolved, quantitative description of SPI as general phenomenon of bacterial populations.

Lyme borreliosis is a tick-borne, multi-systemic infectious disease that is thought to be wide spread in Turkey even though studies on its seroprevalence are limited. To determine the seroprevalence of Lyme borreliosis in part of north-eastern Tur-key (in the city of Trabzon), and to identify possible relationships between seropositivity and various factors such as location, gender, age group, occupation, income, and educational level. Retrospective cross-sectional study. A total of 884 blood samples collected from provincial and district health centers serving a population of about 800,000 were included in this study. ELISA was used to determine the anti-Borrelia IgG antibody levels in the samples. Samples that yielded positive results by ELISA were further subjected to western blot (WB). IgG antibodies were found in 128 samples (14.5%). Statistical analysis revealed significant differences between age groups and educational levels in terms of the incidence of seropositivity, whereas location, gender, occupational group and income level had no effect (p<0.001, p<0.001, p=0.948, p=0.645, p=0.131, p=0.080 respectively). The risk of contracting Lyme borreliosis in Trabzon is high, and necessary measures need to be taken to avoid the spread of disease.

The barriers to HIV testing and counselling that migrants encounter can jeopardize proactive HIV testing that relies on the fact that HIV testing must be linked to care. We analyse available evidence on HIV testing and counselling strategies targeting migrants and ethnic minorities in high-income countries. Systematic literature review of the five main databases of articles in English from Europe, North America and Australia between 2005 and 2009. Of 1034 abstracts, 37 articles were selected. Migrants, mainly from HIV-endemic countries, are at risk of HIV infection and its consequences. The HIV prevalence among migrants is higher than the general population's, and migrants have higher frequency of delayed HIV diagnosis. For migrants from countries with low HIV prevalence and for ethnic minorities, socio-economic vulnerability puts them at risk of acquiring HIV. Migrants have specific legal and administrative impediments to accessing HIV testing-in some countries, undocumented migrants are not entitled to health care-as well as cultural and linguistic barriers, racism and xenophobia. Migrants and ethnic minorities fear stigma from their communities, yet community acceptance is key for well-being. Migrants and ethnic minorities should be offered HIV testing, but the barriers highlighted in this review may deter programs from achieving the final goal, which is linking migrants and ethnic minorities to HIV clinical care under the public health perspective.

Changes in sleep patterns and increased substance involvement are common in adolescence, but our knowledge of the nature of their association remains limited. The aim of this study was to examine the association between several sleep problems and sleep behaviours, and use and misuse of alcohol and illicit drugs using data from a large population-based sample. A large population-based study from Norway conducted in 2012, the youth@hordaland study, surveyed 9328 adolescents aged 16-19 years (54% girls). Self-reported sleep measures provided information on sleep duration, sleep deficit, weekday bedtime and bedtime difference and insomnia. The main dependent variables were frequency and amount of alcohol consumption and illicit drug use, in addition to the presence of alcohol and drug problems as measured by CRAFFT. The results showed that all sleep parameters were associated with substance involvement in a dose-response manner. Short sleep duration, sleep deficit, large bedtime differences and insomnia were all significantly associated with higher odds of all alcohol and drug use/misuse measures. The associations were only partly attenuated by sociodemographics factors and co-existing symptoms of depression and ADHD. To the best of our knowledge, this is the first population-based study to examine the association between sleep, and alcohol and drug use, by employing detailed measures of sleep behaviour and problems, as well as validated measures on consumption of alcohol and illicit drug use. The findings call for increased awareness of the link between sleep problems and alcohol and drugs use/misuse as a major public health issue. Copyright © 2015 Elsevier Ireland Ltd.

Full Text Available Abstract Background Fine-scale or spatial genetic structure (SGS is one of the key genetic characteristics of plant populations. Several evolutionary and ecological processes and population characteristics influence the level of SGS within plant populations. Higher fine-scale genetic structure may be expected in peripheral than core populations of long-lived forest trees, owing to the differences in the magnitude of operating evolutionary and ecological forces such as gene flow, genetic drift, effective population size and founder effects. We addressed this question using eastern white cedar (Thuja occidentalis as a model species for declining to endangered long-lived tree species with mixed-mating system. Results We determined the SGS in two core and two peripheral populations of eastern white cedar from its Maritime Canadian eastern range using six nuclear microsatellite DNA markers. Significant SGS ranging from 15 m to 75 m distance classes was observed in the four studied populations. An analysis of combined four populations revealed significant positive SGS up to the 45 m distance class. The mean positive significant SGS observed in the peripheral populations was up to six times (up to 90 m of that observed in the core populations (15 m. Spatial autocorrelation coefficients and correlograms of single and sub-sets of populations were statistically significant. The extent of within-population SGS was significantly negatively correlated with all genetic diversity parameters. Significant heterogeneity of within-population SGS was observed for 0-15 m and 61-90 m between core and peripheral populations. Average Sp, and gene flow distances were higher in peripheral (Sp = 0.023, σg = 135 m than in core (Sp = 0.014, σg = 109 m populations. However, the mean neighborhood size was higher in the core (Nb = 82 than in the peripheral (Nb = 48 populations. Conclusion Eastern white cedar populations have significant fine-scale genetic structure at short
The purpose of this review was to identify current terms and definitions used to identify and describe children and adolescents who require technology. A total of 400 articles published from January 2000 through May 2012 were reviewed; 26 articles met the inclusion criteria. The review included only primary research studies that focused on a child and adolescent sample (birth to 18 years old) who required technology. Current terms and definitions used to describe children and adolescents who require technology include technology and complex care. Technology is a constant in both terminology and definitions, and it differentiates this population from the general population of children with chronic illness and special health care needs. This review highlights the need for better, more detailed descriptions of the population of children and adolescents who require technology in their daily lives. © The Author(s) 2014.

This study is a part of a monitoring program for the determination of metals in various human tissues of the population living in the vicinity of a new hazardous waste incinerator (HWI) in Constantí (Tarragona County, Spain). Concentrations of arsenic (As), beryllium (Be), cadmium (Cd), chromium (Cr), mercury (Hg), manganese (Mn), nickel (Ni), lead (Pb), tin (Sn), thallium (Tl), and vanadium (V) were determined in brain, bone, kidney, liver, and lung autopsy samples collected in 2003 from 22 individuals who had been living for at least 10 yr in the area under evaluation. Results were compared with the metal levels obtained in a baseline study, which was performed during the construction of the HWI (1996--1998). In the present survey, As, Be, Tl, and V levels were not detected in any of the analyzed tissues, while Cr concentrations were very close to the limit of detection. The highest levels of Cd and Hg were found in kidney (17.46 microg/g and 0.23 microg/g, respectively), those of Mn in liver (1.07 microg/g), and those of Ni, Pb, and Sn in bone (1.16 microg/g, 2.11 microg/g, and 0.34 microg/g, respectively). In comparison to the results of the baseline study, a general reduction of most metal concentrations was observed in the current survey.

The objective of this study was to describe breastfeeding practices and to compare the risk of suboptimal breastfeeding of women living in Denmark according to country of origin, and further to examine how socio-economic position and duration of stay in the country affected this risk. Information on breastfeeding of 42,420 infants born 2002-2009 and living in eighteen selected Danish municipalities was collected from the Danish Health Visitor's Child Health Database. The data was linked with data on maternal socio-demographic information from Danish population-covering registries. Suboptimal breastfeeding was defined as country of origin, and taking maternal age and parity, and a variety of parental socio-economic measures into account. Suboptimal breastfeeding was more frequent among non-Western migrant women than among women of Danish origin. Women who were descendants of Turkish and Pakistani immigrants had a higher risk of suboptimal breastfeeding as compared to the group of women who had migrated from the same countries, suggesting that acculturation did not favor breastfeeding. For all but the group of women who had migrated from Pakistan, adjustment for socio-demographic indicators (age, parity, education, attachment to labour market, and income) eliminated the increased risk of suboptimal breastfeeding. There was no evidence for differences in the breastfeeding support provided at hospital level according to migrant status. Suboptimal breastfeeding was more frequent among women who were non-Nordic migrants and descendants of migrants than among women with Danish origin.

The aim of the study was to investigate mental health and resilience in adolescents who have been internationally adopted and their non-adopted peers and examine the potential interaction between adoption status and resilience on mental health problems. Data from the population based youth@hordaland-survey, conducted in Hordaland County, Norway, in 2012 was used. In all, 10 257 adolescents aged 16-19 years provided self-reported data on several mental health instruments. Of these, 45 adolescents were identified as internationally adopted. Adoptees reported more symptoms of depression, attention-deficit/hyperactivity disorder (ADHD), obsessive compulsive disorder (OCD) and perfectionism than non-adopted adolescents, but there were no differences regarding resilience. Adolescents with higher resilience scores reported fewer symptoms of mental health problems, however, no interaction effects were found for adoption status and total resilience score on measures of mental health problems. Our findings indicate that knowledge of resilience factors can form the basis for preventive interventions.
Full Text Available Abstract Background High prevalence rates for rheumatoid arthritis, spondyloarthopathies, and systemic lupus erythematosus have been described in American Indian and Alaskan Native adults. The impact of these diseases on American Indian children has not been investigated. Methods We used International Classification of Diseases-9 (ICD-9 codes to search two Indian Health Service (IHS patient registration databases over the years 1998–2000, searching for individuals 19 years of age or younger with specific ICD-9-specified diagnoses. Crude estimates for disease prevalence were made based on the number of individuals identified with these diagnoses within the database. Results Rheumatoid arthritis (RA / juvenile rheumatoid arthritis (JRA was the most frequent diagnosis given. The prevalence rate for JRA in the Oklahoma City Area was estimated as 53 per 100,000 individuals at risk, while in the Billings Area, the estimated prevalence was nearly twice that, at 115 per 100,000. These rates are considerably higher than those reported in the most recent European studies. Conclusion Chronic arthritis in childhood represents an important, though unrecognized, chronic health challenge within the American Indian population living in the United States.

Contexte : Peu d’études en population générale ont décrit le risque d’issues néonatales indésirables chez les femmes vivant avec le VIH au Canada. Par conséquent, nous avons comparé les risques d’accouchement préterme (APT), de faible poids de naissance (FPN) et d’hypotrophie fœtale (HF) chez des Ontariennes de 18-49 ans vivant ou non avec le VIH. Méthodes : Nous avons mené une étude en population générale au moyen de données administratives sur la santé en Ontario. Des équations d’estimation généralisées comptant une fonction Logit ont été utilisées pour en venir à des rapports de cotes corrigés (RCc) et à des intervalles de confiance à 95 % en ce qui concerne l’association entre l’infection au VIH et des issues néonatales indésirables. Résultats : Entre 2002–2003 et 2010–2011, 1 113 874 naissances vivantes issues de grossesses monofœtales étaient disponibles aux fins de l’analyse, 615 (0,06 %) desquelles mettaient en jeu des femmes vivant avec le VIH. La proportion de naissances issues de grossesses monofœtales qui présentaient une HF (14,6 % vs 10,3 %; P VIH que chez les femmes n’étant pas infectées par ce dernier. À la suite d’une correction multivariée, les risques d’APT (RCc, 1,76; IC à 95 %, 1,38 - 2,24), d’HF (RCc, 1,43; IC à 95 %, 1,12 - 1,81) et de FPN (RCc, 1,90; IC à 95 %, 1,47 - 2,45) étaient plus élevés chez les femmes vivant avec le VIH que chez les femmes n’étant pas infectées par ce dernier. Conclusion : Les femmes vivant avec le VIH sont exposées à des risques d’issues néonatales indésirables plus élevés que les femmes séronégatives pour le VIH. La tenue d’autres recherches s’avère requise pour que l’on puisse élaborer des interventions préconceptionnelles et prénatales qui pourraient atténuer le fardeau supplémentaire que doivent assumer les femmes vivant avec le VIH en matière de piètres issues de grossesse.

Detailed descriptions of the dentition of many strepsirhine primate taxa are rare, despite their importance in understanding primate evolutionary biology. While several researchers have provided detailed morphological descriptions of ring-tailed lemur dentition (e.g., Schwartz and Tattersall  Am. Mus. Nat. Hist. Anthropol. Pap. 60:1-100; Tattersall and Schwartz  Am. Mus. Nat. Hist. Anthropol. Pap. 69:2-18), there are few studies (e.g., Eaglen  Am. J. Phys. Anthropol. 71:185-201) that present quantitative data on the dentition of this species. Furthermore, prior analyses were based on museum specimens from various populations and locations. We present here quantitative and morphological data on the dentition of a population of wild Lemur catta from Beza Mahafaly Special Reserve, Madagascar. Measurements were made on dental casts (n = 39) taken from living members of this L. catta population. Our analysis indicates that no significant (P > 0.05) sexual dimorphism exists for the 30 dental measurements collected. These data support the generalizations (e.g., Plavcan and van Schaik  Evol. Anthropol. 2:208-214; Kappeler  J. Evol. Biol. 9:43-65) that little sexual dimorphism in dentition exists among Malagasy strepsirhines. In addition, the overall patterns of metric variation in this sample compare favorably with patterns seen among other primates, e.g., premolar measurements varying more than molars (e.g., Gingerich  J. Paleontol. 48:895-903). However, there is a degree of intraspecific morphological variation indicated, with one of the morphological traits discussed in other studies as being species-specific for L. catta (absence of P(4) metaconids) observed to vary between specimens. Because the patterns of variation seen in this sample are from a known breeding population, the data presented here provide an important reference for interpreting and understanding the fossil record.
The notion of an attractor has been widely employed in thinking about the nonlinear dynamics of organisms and biological phenomena as systems and as processes. The notion of a landscape with valleys and mountains encoding multiple attractors, however, has a rigorous foundation only for closed, thermodynamically non-driven, chemical systems, such as a protein. Recent advances in the theory of nonlinear stochastic dynamical systems and its applications to mesoscopic reaction networks, one reaction at a time, have provided a new basis for a landscape of open, driven biochemical reaction systems under sustained chemostat. The theory is equally applicable not only to intracellular dynamics of biochemical regulatory networks within an individual cell but also to tissue dynamics of heterogeneous interacting cell populations. The landscape for an individual cell, applicable to a population of isogenic non-interacting cells under the same environmental conditions, is defined on the counting space of intracellular chemical compositions x = (x1,x2, … ,xN) in a cell, where xℓ is the concentration of the ℓth biochemical species. Equivalently, for heterogeneous cell population dynamics xℓ is the number density of cells of the ℓth cell type. One of the insights derived from the landscape perspective is that the life history of an individual organism, which occurs on the hillsides of a landscape, is nearly deterministic and ‘programmed’, while population-wise an asynchronous non-equilibrium steady state resides mostly in the lowlands of the landscape. We argue that a dynamic ‘blue-sky’ bifurcation, as a representation of Waddington's landscape, is a more robust mechanism for a cell fate decision and subsequent differentiation than the widely pictured pitch-fork bifurcation. We revisit, in terms of the chemostatic driving forces upon active, living matter, the notions of near-equilibrium thermodynamic branches versus far-from-equilibrium states. The emergent

Self-management programmes are complex interventions aimed at improving the way individuals self-manage chronic conditions, but there are questions about the overall impact of these programmes on disadvantaged populations, in terms of their capacity to engage with and receive the benefits from these initiatives. Given the increased resources being directed towards self-management initiatives, clinicians and policy makers need knowledge on how self-management interventions work for these populations. Most systematic reviews of self-management interventions do not consider the complex interactions between implementation contexts, intervention strategies, and mechanisms that influence how self-management interventions work in real life for disadvantaged groups. To address the need for better understanding of these mechanisms and to create context-relevant knowledge, we are conducting a realist synthesis of evidence on self-management interventions for disadvantaged populations living with chronic conditions. The primary research question is: What are the key mechanisms operating in chronic condition self-management interventions among disadvantaged populations? In this protocol, we outline the steps we will take to identify the programme theory for self-management interventions and candidate middle-range theories; to search for evidence in academic and grey literature; to appraise and extract the collected evidence; to synthesise and interpret the findings to generate key context-mechanism-outcome configurations and to disseminate results to relevant stakeholder and to peer-review publications. Understandings of how chronic conditions self-management interventions work among disadvantaged populations is essential knowledge for clinicians and other decision makers who need to know which programmes they should implement for which groups. Results will also benefit medical researchers who want to direct effort towards current gaps in knowledge in order to advance the self

Social networking sites (SNSs) have gained considerable popularity among youth in recent years; however, there is a noticeable paucity of research examining the association between the use of these web-based platforms and cyberbullying victimization at the population level. This study examines the association between the use of SNSs and cyberbullying victimization using a large-scale survey of Canadian middle and high school students. Data on 5,329 students aged 11-20 years were derived from the 2013 Ontario Student Drug Use and Health Survey. Logistic regression was used to examine the relationship between the use of SNSs and cyberbullying victimization while adjusting for covariates. Overall, 19 percent of adolescents were cyberbullied in the past 12 months. Adolescents who were female, younger, of lower socioeconomic status, and who used alcohol or tobacco were at greater odds of being cyberbullied. The use of SNSs was associated with an increased risk of cyberbullying victimization in a dose-response manner (p-trend cyberbullied. Results from this study underscore the need for raising awareness and educating adolescents on effective strategies to prevent cyberbullying victimization.

The human health impact of the historic and current mining and industrial activities in Tunisia is not known. This study assessed the exposure to metals in the population of Southern Tunisia, using biomonitoring. The aim of this pilot study was to evaluate metal exposure on 350 participants living near mining and active industrial areas in the South of Tunisia. Blood specimens were analyzed for metals (Cd, Cr, As, and Ni) by Atomic Absorption Spectrometer equipped with Zeeman background correction and AS-800 auto sampler by graphite furnace and graphite tubes with integrated L'vov platform. The sample population was classified according to different age groups, sex, smoking habit, sea food and water drinking consumption, occupational exposure, amalgam fillings and place of residence. The blood As, Cd, Cr and Ni values expressed as mean ± SD were 1.56 ± 2.49, 0.74 ± 1.15, 35.04 ± 26.02 and 30.56 ± 29.96 μg/l, respectively. Blood Cd and Ni levels in smokers were 2 and 1.2 times, respectively, higher than in non-smokers. Blood Cd levels increase significantly with age (p = 0.002). As, Cd and Ni were significantly correlated with gender and age (p Tunisia reveals a substantial exposure to several metals. The pathways of exposure and health significance of these findings need to be further investigated.

Mining industry is a vital economic sector for many countries but it is also one of the most hazardous activities, both occupationally and environmentally. Existing studies point to several adverse effects on communities' health living near mines, effects such as mesothelioma and respiratory illnesses. Results achieved in a geochemical sampling campaign undertaken in the vicinity of São Francisco de Assis village showed an anomalous distribution of some heavy metals in soils and waters. To evaluate the effects of mining activities on human health produced by these conditions, a group of 28 individuals from São Francisco de Assis village was examined for some biological endpoints. A nonexposed group (30 individuals) with the same demographic characteristics without exposure to genotoxic compounds was also studied and data obtained from both groups compared. Results of the T-cell receptor mutation assay and micronucleus (MN) test showed significant increases in the frequencies of both mutations and MN in exposed subjects compared to controls. Data obtained in the analysis of the different lymphocyte subsets demonstrated significant decreases in percentages of CD3+ and CD4+ cells, and a significant increase in percentage of CD16/56+ cells, in exposed individuals. The results of the present study indicate an elevated risk of human environmental contamination resulting from mining activities, emphasizing the need to implement preventive measures, remediation, and rehabilitation plans. This would lead to a reduction in cancer risk not only for this particular population but for all populations exposed under similar conditions.

Full Text Available Background: Despite increase in accessibility and utilization of maternal health services in the state of Telangana, penetration of these services in vulnerable communities is inadequate. Aims & Objectives: To understand the determinants of utilization of reproductive health services by migrant population living in non-notified slums of Hyderabad city in the Indian state of Telangana. Material & Methods: It is a community based cross sectional study of 761 rural to urban internal migrant mothers with a child of less than 2 years of age residing for a period minimum of 30 days and not more than 10 years. Information was collected for socio demographic details, antenatal care and child delivery. Results: Mothers receiving at least 4 antenatal care visits and institutional deliveries in migrants was 69.6% and 69% respectively, compared to 85.8% and 97% in general population of Hyderabad city. The likelihood of mothers receiving adequate care is 6.7 times higher in mothers with secondary education compared to formal education. The likelihood of institutional delivery is 7.8 times higher in mothers availing adequate antenatal care versus inadequate care and 2.2 times higher in mothers with secondary education versus formal education. Conclusion: Utilization of antenatal care services and promotion of institutional deliveries can be improved by acting on the supply side barriers such as health care infrastructure and demand side barriers such as indirect consumer costs, financial constraints and community engagement
Full Text Available Background. Longitudinal investigations into the origins of adult essential hypertension have found elevated blood pressure in children to accurately track into adulthood, however the direct causes of essential hypertension in adolescence and adulthood remains unclear.Methods. We revisited 152 Peruvian adolescents from a birth cohort tracked from 0 to 30 months of age, and evaluated growth via monthly anthropometric measurements between 1995 and 1998, and obtained anthropometric and blood pressure measurements 11–14 years later. We used multivariable regression models to study the effects of infantile and childhood growth trends on blood pressure and central obesity in early adolescence.Results. In regression models adjusted for interim changes in weight and height, each 0.1 SD increase in weight for length from 0 to 5 months of age, and 1 SD increase from 6 to 30 months of age, was associated with decreased adolescent systolic blood pressure by 1.3 mm Hg (95% CI −2.4 to −0.1 and 2.5 mm Hg (95% CI −4.9 to 0.0, and decreased waist circumference by 0.6 (95% CI −1.1 to 0.0 and 1.2 cm (95% CI −2.3 to −0.1, respectively. Growth in infancy and early childhood was not significantly associated with adolescent waist-to-hip ratio.Conclusions. Rapid compensatory growth in early life has been posited to increase the risk of long-term cardiovascular morbidities such that nutritional interventions may do more harm than good. However, we found increased weight growth during infancy and early childhood to be associated with decreased systolic blood pressure and central adiposity in adolescence.

Background: Socioeconomic status (SES) is a major determinant of health inequality in children and adolescents. The aim of this study was to evaluate the association of SES of family and living region with self-rated health (SRH) and life satisfaction (LS) among children and adolescents. Methods: This study was a part of the fourth survey of a national surveillance program, which was conducted in 30 provinces of Iran in 2011-2012. LS and SRH were assessed by a questionnaire based on the World Health Organization-Global School-based student Health Survey (WHO-GSHS). Family SES was estimated using principal component analysis (PCA) and based on family assets, parental education and occupation, and type of school. Region SES was calculated using PCA and some variables including literacy rate, family assets and employment rate. Results: Out of 14,880 invited students, 13,486 (participation rate: 90.6%) completed the survey; of whom, 49.2% were girls, and 75.6% were from urban areas with the mean ± SD age of 12.47±3.36 years. In the multivariate model, SES of family and living region was associated with LS and good SRH. In the full models, in addition to all potential confounders, family and living region SES were included simultaneously. However, only the association of family SES with LS, and good SRH remained statistically significant. Conclusion: The effect of families' SES on SRH and LS is more important than regional SES. The presented patterns of SRH and LS may be useful in developing better health policies and conducting complementary studies in this field.
Full Text Available BACKGROUND: Adolescent idiopathic scoliosis (AIS is one of the most common spinal deformities found in adolescent populations. Recently, a genome-wide association study (GWAS in a Japanese population indicated that three single nucleotide polymorphisms (SNPs, rs11190870, rs625039 and rs11598564, all located near the LBX1 gene, may be associated with AIS susceptibility . This study suggests a novel AIS predisposition candidate gene and supports the hypothesis that somatosensory functional disorders could contribute to the pathogenesis of AIS. These findings warrant replication in other populations. METHODOLOGY/PRINCIPAL FINDINGS: First, we conducted a case-control study consisting of 953 Chinese Han individuals from southern China (513 patients and 440 healthy controls, and the three SNPs were all found to be associated with AIS predisposition. The ORs were observed as 1.49 (95% CI 1.23-1.80, P = 5.09E-5, 1.70 (95% CI 1.42-2.04, P = 1.17E-8 and 1.52 (95% CI 1.27-1.83, P = 5.54E-6 for rs625039, rs11190870 and rs11598564, respectively. Second, a case-only study including a subgroup of AIS patients (N = 234 was performed to determine the effects of these variants on the severity of the condition. However, we did not find any association between these variants and the severity of curvature. CONCLUSION: This study shows that the genetic variants near the LBX1 gene are associated with AIS susceptibility in Chinese Han population. It successfully replicates the results of the GWAS, which was performed in a Japanese population.

Pediatric persistent pain is associated with poorer physical and psychosocial functioning in children, as well as immediate and long-term societal costs. Onset typically occurs in early adolescence, suggesting that late childhood is a key window for identifying potential intervention targets before pain symptoms become entrenched. This study used population-based data from the Longitudinal Study of Australian Children (n = 3,812) and adopted a biopsychosocial and ecological systems approach to investigate child, family, and sociodemographic factors associated with pain problems in children transitioning to adolescence. The prevalence of at least weekly parent-reported pain in the study sample was approximately 5% at 10 to 11 years of age, and pain continued at 12 to 13 years of age for 40% of these children. Key factors at 10 to 11 years that uniquely predicted parent-reported pain problems at 12 to 13 years were frequency of previous pain (1-3 times weekly: odds ratio [OR] = 7.49; 95% confidence interval [CI], 4.3-13.0; 4-7 times weekly: OR = 17.8; 95% CI, 8.7-36.5) and sleep difficulties (OR = 1.86; 95% CI, 1.16-2.97). This study highlights the importance of early intervention for persistent pain in childhood, because pain complaints in late childhood tend to persist into early adolescence. This article used a biopsychosocial and ecological systems approach to understanding predictors of pain problems during the transition to adolescence within a nationally representative community-based cohort. Sleep difficulties at 10 to 11 years uniquely predicted pain at ages 12 to 13 years, suggesting that early intervention using sleep interventions may be a promising direction for future research.

We conducted interviews of a representative sample of 106 retired fishers in Italy, Spain and Greece, asking specific questions about the trends they perceived in dolphin and shark abundances between 1940 and 1999 (in three 20 year periods) compared to the present abundance. The large marine fauna studied were not target species of the commercial fleet segment interviewed (trawl fishery). The fishers were asked to rank the perceived abundance in each period into qualitative ordinal classes based on two indicators: frequency of sightings and frequency of catches (incidental or intentional) of each taxonomic group. The statistical analysis of the survey results showed that both incidental catches and the sighting frequency of dolphins have decreased significantly over the 60+ years of the study period (except for in Greece due to the recent population increase). This shows that fishers' perceptions are in agreement with the declining population trends detected by scientists. Shark catches were also perceived to have diminished since the early 1940s for all species. Other long-lived Mediterranean marine fauna (monk seals, whales) were at very low levels in the second half of the 20th century and no quantitative data could be obtained. Our study supports the results obtained in the Mediterranean and other seas that show the rapid disappearance (over a few decades) of marine fauna. We show that appropriately designed questionnaires help provide a picture of animal abundance in the past through the valuable perceptions of fishers. This information can be used to complement scientific sources or in some cases be taken as the only information source for establishing population trends in the abundance of sensitive species.

The increased life expectancy of perinatally HIV-infected adolescents necessitates the transition from pediatric to adult infectious disease care. Significant differences exist between pediatric and adult HIV clinic models, and adequate preparation is critical for successful transition. The expectations of youth on the cusp of this transition and their guardians have not previously been explored. Semistructured interviews were conducted with 40 perinatally infected adolescents (mean age, 17.3 years; 90% African American; 57.5% female; 57.5% in high school) currently receiving care in a pediatric infectious disease clinic in the southeast United States and 17 guardians about their expectations related to the pending transition to adult care. Interviews were transcribed and coded for emergent themes. Many adolescents had difficulty articulating expectations of their transition to an adult clinic, reporting they did not know what to expect. Others looked forward to increased responsibility and control, while some expressed concerns over leaving their current providers and having to establish new relationships. Most guardians viewed the transition to adult care as a tool to facilitate maturity. Several indicated they had not discussed transition with their child and were waiting for their child to initiate a conversation about it. Given the importance providers place on preparing youth for transition, it is surprising that many adolescents had no expectations about this impending change. This indicates a need for improved communication between providers and adolescents to enhance preparation and ultimately transition success. Additionally, guardians play an important role in the transition process and may need support to discuss this process with their child.

The purpose of this study was to understand the experiences of Taiwanese aboriginal adolescent survivors of childhood cancer during the process of recovery. A snowball sampling strategy was used to recruit participants from the pediatrics unit of a medical center in the eastern region of Taiwan. In-depth interviews were conducted with 11 aboriginal adolescent childhood cancer survivors. The data were analyzed using content analysis. The results revealed three major themes with subthemes within each theme. The three major themes are: roots of resilience, transformation and growth, and meaning of traditional rituals for resilience. The three subthemes within "roots of resilience" include: "feeling secure through company of family, care and financial support", "receiving support from the important others and religion" and "learning to self-adjust". The three subthemes revealed within "transformation and growth" are: restructuring the relationship with peers, "appreciating parents' hard work", and "learning to seize the moment". The two subthemes within "meaning of traditional rituals to resilience" include: "feeling blessed with the power of ancestral spirits" and "strengthening ethnic identity". This study provided insight into the experiences of aboriginal adolescents as they recovered from childhood cancer. The experiences made positive impacts by inspiring growth in maturity and consolidating aboriginal ethnic identity. The adolescents were empowered by support from family, friends and clansmen, and by their participation in aboriginal rituals. As healthcare professionals care for the aboriginal adolescents, it is critical to consider this culturally and ethnically specific knowledge/experience of surviving cancer to improve quality of care.

Adolescents at risk for suicide often see their general practitioner solely for somatic or administrative reasons. A simple screening test given during a conversation would be of substantial help to send a signal and tackle the problem. We propose to update a screening test previously validated in France - the TSTS-Cafard - because of significant changes in the lives of adolescents with the growth of the cyber world since 2000. The design and setting was a cross-sectional study involving 912 15-year-old adolescents in 90 French schools. They completed a questionnaire that included the TSTS-Cafard and risk factors extracted from the Health Behaviour in School-Aged Children survey. To improve the test, we selected questions drawn from the recent literature. Answers were analysed according to 'suicidality' = at least one suicide attempt in life or suicidal ideation often over the past 12 months. Suicidality rates were 9.6% for boys and 23.1% for girls. Although the TSTS-Cafard test was generally effective, one question was no longer discriminating. A new test, entitled 'BITS', included only four questions on bullying, insomnia, tobacco and stress, with three levels of response and scores ranging from 0 to 8. Improvement was achieved without loss of performance. Using a cut-off score of 3, we achieved 78% accuracy (area under the curve), 75% sensitivity and 70% specificity. The BITS test could allow the question of suicide risk to be addressed during a routine check-up in primary care but the results need to be validated with 13 to 18-year olds. © 2016 John Wiley & Sons Australia, Ltd.

The reproductive and sexual health of adolescents is an important health concern and a focus of global attention. In Sri Lanka, a lack of understanding about adolescent reproductive and sexual health needs is a matter of national concern. A survey was undertaken to examine the sexual knowledge, attitudes and behaviours of school going adolescents in Sri Lanka. A random sample of schools was selected from one district. Data were collected by a self-completion questionnaire and analysed using SPSS. Response rate was 90%. 2020 pupils (26% boys, 74% girls) aged 16-19 years (mean=16.9) participated, the majority Sinhalese (97%). Most reported a good parent-child relationship (88%). A minority (34%) discussed sexual issues with parents. Health professionals were the preferred source of sexual information (32%) rather than parents (12.5%) or friends (5.6%). Less than 1% demonstrated satisfactory sexual and reproductive knowledge levels. 1.7% were sexually active (30 boys vs 5 girls), the majority with same age partners. 57% used contraception at first intercourse. There is an imperative to address the lack of sexual and reproductive knowledge. A minority of school going adolescents become sexually active. These individuals are potentially vulnerable and services need to be developed to meet their needs.

There is growing concern over the adverse health, social, economic, and demographic effects of adolescent fertility. Morbidity and mortality rates ar significantly higher for teenage mothers and their infants, and early initiation of childbearing generally means truncated education, lower future family income, and larger completed family size. Adolescent fertility rates, which largely reflect marriage patterns, range from 4/1000 in Mauritania; in sub-Saharan Africa, virtually all rates are over 100. In most countries, adolescent fertility rates are declining due to rising age at marriage, increased educational and economic opportunities for young women, changes in social customs, increased use of contraception, and access to abortion. However, even if fertility rates were to decline dramatically among adolescent women in developing countries, their sheer numbers imply that their fertility will have a major impact on world population growth in the years ahead. The number of women in the world ages 15-19 years is expected to increase from 245 million in 1985 to over 320 million in the years 2020; 82% of these women live in developing countries. As a result of more and earlier premarital sexual activity, fostered by the lengthening gap between puberty and marriage, diminished parental and social controls, and increasing peer and media pressure to be sexually active, abortion and out-of-wedlock childbearing are increasing among teenagers in many developed and rapidly urbanizing developing countries. Laws and policies regarding sex education in the schools and access to family planning services by adolescents can either inhibit or support efforts to reduce adolescent fertility. Since contraceptive use is often sporadic and ineffective among adolescents, family planning services are crucial. Such programs should aim to reduce adolescents' dependence on abortion through preventive measures and increase awareness of the benefits of delayed sexual activity. Similarly, sex
While a great deal of research has been conducted on prodromal risk syndromes in relation to help-seeking individuals who present to the clinic, there is a lack of research on prodromal risk syndromes in the general population. The current study aimed first to establish whether prodromal risk syndromes could be detected in non-help-seeking community-based adolescents and secondly to characterize this group in terms of Axis-1 psychopathology and general functioning. We conducted in-depth clinical interviews with a population sample of 212 school-going adolescents in order to assess for prodromal risk syndromes, Axis-1 psychopathology, and global (social\\/occupational) functioning. Between 0.9% and 8% of the community sample met criteria for a risk syndrome, depending on varying disability criteria. The risk syndrome group had a higher prevalence of co-occurring nonpsychotic Axis-1 psychiatric disorders (OR = 4.77, 95% CI = 1.81-12.52; P < .01) and poorer global functioning (F = 24.5, df = 1, P < .0001) compared with controls. Individuals in the community who fulfill criteria for prodromal risk syndromes demonstrate strong similarities with clinically presenting risk syndrome patients not just in terms of psychotic symptom criteria but also in terms of co-occurring psychopathology and global functioning.

Internationally adopted adolescents are at increased risk for mental health problems. However, little is known about problematic alcohol and drug use, which are important indicators of maladjustment. The aim of this study was to examine the level of problematic alcohol and drug use in internationally adopted adolescents compared to their nonadopted peers. The study is based on data from the youth@hordaland-survey, which was conducted in Hordaland County, Norway, in the spring of 2012. All adolescents born from 1993 to 1995 residing in Hordaland at the time of the study were invited to participate. Information on adoption was obtained from the Central Adoption Registry and linked to self-report data from the youth@hordaland-survey. Among 10,200 participants, 45 were identified as internationally adopted. No significant differences were found between international adoptees and their peers regarding whether or not they had tried alcohol or illicit drugs or their patterns of drinking behavior. However, adopted adolescents had a higher mean score on a measure of problematic alcohol and drug use compared to their nonadopted peers. The difference was attenuated and no longer significant when adjusting for measures of depression and attention-deficit/hyperactivity disorder. Results from a structural equation model indicated a full mediation effect of mental health problems on the association between adoption status and problematic alcohol and drug use. Our findings indicate that internationally adopted adolescents experience more problematic alcohol and drug use than their nonadopted peers, and the difference can largely be explained by mental health problems.

Full Text Available Background Malignant wound causes a devastating physical and psychological condition in cancer patients. This study presents a review which can provide better insights into the life of cancer patients living with malignant wound. The aim of this meta-synthesis was to analyze and synthesize findings from qualitative studies of the lived experiences of patients with malignant wound. Materials and Methods This meta-synthesis followed the Sandelowski and Barroso’s guideline and was designed to synthesize findings from previous qualitative studies. Variety of biomedical archives were searched, including PubMed, Web of Science, PsycINFO, Cochrane library, and ProQuest and Persian data bases such as Magiran, SID, Iran.doc, IranMedex, and recently published articles and books on the lived experience of persons living with malignant wound were reviewed. In this article, the literature searches covering from January,1, 1990 to march,15, 2016 resulted in eight relevant studies which fulfilled the inclusion criteria for the review. Results Findings from all these studies were categorized into three main themes: "distortion of lived body", "symptomatic suffering", and "compatible living with wound". Our findings showed that the meanings of patients’ experiences living with malignant wound are important for the construction of multidisciplinary palliative care in these individuals. Conclusion: Gaining insights from analysis of qualitative studies is integral issue for developing new palliative care services for patients with malignant wound.

Full Text Available Adolescent mothers are reportedly at risk for depression and problem behaviors in the postpartum period, but studies have rarely considered developmental context and have yet to disentangle the effects of childbearing on adolescent functioning from selection effects that are associated with early pregnancy. The current study examined changes in adolescent depression, conduct problems and substance use (alcohol, tobacco and marijuana across the peripartum period using risk-set propensity scores derived from a population-based, prospective study that began in childhood (the Pittsburgh Girls Study, PGS. Each of 147 childbearing adolescents (ages 12-19 was matched with two same-age, non-childbearing adolescents (n = 294 on pregnancy propensity using 15 time-varying risk variables derived from sociodemographic, psychopathology, substance use, family, peer and neighborhood domains assessed in the PGS wave prior to each pregnancy (T1. Postpartum depression and problem behaviors were assessed within the first 6 months following delivery (T2; data gathered from the non-childbearing adolescent controls spanned the same interval. Within the childbearing group, conduct problems and marijuana use reduced from T1 to T2, but depression severity and frequency of alcohol or tobacco use showed no change. When change was compared across the matched groups, conduct problems showed a greater reduction among childbearing adolescents. Relative to non-childbearing adolescents who reported more frequent substance use with time, childbearing adolescents reported no change in alcohol use and less frequent use of marijuana across the peripartum period. There were no group differences in patterns of change for depression severity and tobacco use. The results do not support the notion that adolescent childbearing represents a period of heightened risk for depression or problem behaviors.
Abstract Background The negative effects of stigma on persons living with HIV (PLHIV) have been documented in many settings and it is thought that stigma against PLHIV leads to more difficulties for those who need to access HIV testing, treatment and care, as well as to limited community uptake of HIV prevention and testing messages. In order to understand and prevent stigma towards PLHIV, it is important to be able to measure stigma within communities and to understand which factors are associated with higher stigma. Methods To analyze patterns of community stigma and determinants to stigma toward PLHIV, we performed an exploratory population-based survey with 1874 randomly sampled adults within a demographic surveillance site (DSS) in rural Vietnam. Participants were interviewed regarding knowledge of HIV and attitudes towards persons living with HIV. Data were linked to socioeconomic and migration data from the DSS and latent class analysis and multinomial logistic regression were conducted to examine stigma group sub-types and factors associated with stigma group membership. Results We found unexpectedly high and complex patterns of stigma against PLHIV in this rural setting. Women had the greatest odds of belong to the highest stigma group (OR 1.84, 95% CI 1.42-2.37), while those with more education had lower odds of highest stigma group membership (OR 0.45, 95% CI 0.32-0.62 for secondary education; OR 0.19, 95% CI 0.10-0.35 for tertiary education). Long-term migration out of the district (OR 0.61, 95% CI 0.4-0.91), feeling at-risk for HIV (OR 0.42, 95% CI 0.27-0.66), having heard of HIV from more sources (OR 0.44, 95% CI 0.3-0.66), and knowing someone with HIV (OR 0.76, 95% CI 0.58-0.99) were all associated with lower odds of highest stigma group membership. Nearly 20% of the population was highly unsure of their attitudes towards PLHIV and persons in this group had significantly lower odds of feeling at-risk for HIV (OR 0.54, 95% CI 0.33-0.90) or of knowing

Depression is an affective disorder and one of the main contributors to the burden of disease worldwide. Our purpose is to estimate the prevalence of depressive symptoms and associated factors in the population of the Manaus Metropolitan Region. We conducted a population-based, cross-sectional study with a probabilistic three-phase sampling in 2015, based on a previously calculated sample size. Adults living in Manaus and seven inner cities of the metropolitan region were surveyed for depressive symptoms using the Patient Health Questionnaire (PHQ-9) and a cutoff score of ≥ 9. We performed a Poisson regression with robust variance using a hierarchical approach to calculate the prevalence ratio (PR) of depression and 95% confidence intervals (CIs). Among 4001 participants (response rate 76%), the prevalence of current depressive symptoms was 7% (95% CI: 6-8%). Depressive symptoms were more frequent in inhabitants of Manaus than in those from the countryside (PR = 6.13, 95% CI: 2.91-12.91); in women than in men (PR = 2.55, 95% CI: 1.96-3.33); in indigenous than in white people (PR = 2.56, 95% CI: 1.24-5.30); and in those with hypertension (PR = 1.47, 95% CI: 1.13-1.92), cardiac disease (PR = 1.62, 95% CI: 1.12-2.33), and poor health status (fair: PR = 5.10, 95% CI: 2.50-10.37; bad: PR = 10.27, 95% CI: 4.92-21.44 very bad: PR = 21.14, CI 95%: 10.16-43.99). High school education (PR = 0.55, 95% CI: 0.32-0.95) and middle class economic status (PR = 0.33, 95% CI: 0.12-0.89) were protective factors. Limitations include the lack of measurement of physical activity, religious beliefs, leisure time, and use of alcohol and other drugs since these factors can affect depression and health status. Seven out of every 100 adults from the Manaus Metropolitan Region have depressive symptoms. This rate is higher in women, individuals living in Manaus, indigenous people, people with hypertension or chronic cardiac disease, and those with a poor health status. Copyright © 2017

Due to advances in highly active antiretroviral treatment (HAART), children "who perinatally acquired HIV infection" (PHIV+) in the United States have been reaching adolescence and adulthood in large numbers. As youth PHIV + become sexually active it is important to understand their sources of sexual health information and the messages communicated by those sources to safeguard their sexual health and that of their partners. This paper explores sexual health communication for adolescent girls PHIV + in comparison to adolescent girls who were exposed but did not acquire HIV perinatally (PHIV-) to understand how HIV infection influences the sexual health communication needs of the former. A convenience sample size of 30 (20 PHIV + and 10 PHIV-, mean age 14.5) girls completed survey and participated in a 45-90 min developmentally appropriate semi-structured interview. The interviews aimed to elicit the girls' sources of sexual health communication, the sexual health messages they receive, their comfort or discomfort with these communications, and to determine how their sexual health communication experiences differ from those of their PHIV- peers. Transcripts of the interviews were coded and analyzed for themes related to sexual health communication sources, sexual health communication messages and comfort/discomfort with sexual health communication sources. Our findings suggest that girls PHIV + do not differ significantly from Girls PHIV- in their sources of sexual health information, yet girls PHIV + are most comfortable receiving sexual health information from their health providers, whereas for girls PHIV, the comfort is higher with caregivers. However, the messages Girls PHIV + reported receiving from their providers and caregivers were vague. Both providers and caregivers of Girls PHIV + are uniquely positioned to provide information to adolescents about sexuality and responsible sex decision-making. Some caregivers and providers

METHOD: Reliability and correlation analyses were conducted for both TCI versions, 2,714 CATSS-twins were compared to 631 adolescents from the general population, and the genetic structure was investigated through univariate genetic analyses, using a model-fitting approach with structural equation-modeling techniques based on same-sex twin pairs from the CATSS (423 monozygotic and 408 dizygotic pairs. RESULTS: The TCI scores from the short and long versions showed comparable reliability coefficients and were strongly correlated. Twins scored about half a standard deviation higher in the character scales. Three of the four temperament dimensions (Novelty Seeking, Harm Avoidance, and Persistence had strong genetic and non-shared environmental effects, while Reward Dependence and the three character dimensions had moderate genetic effects, and both shared and non-shared environmental effects.

Body segment parameters (BSP) for each body׳s segment are needed for biomechanical analysis. To provide population-specific BSP, precise estimation of body׳s segments volume and density are needed. Widely used uniform densities, provided by cadavers׳ studies, did not consider the air present in the lungs when determining the thorax density. The purpose of this study was to propose a new uniform thorax density representative of the living population from 3D external body shape modeling. Bi-planar X-ray radiographies were acquired on 58 participants allowing 3D reconstructions of the spine, rib cage and human body shape. Three methods of computing the thorax mass were compared for 48 subjects: (1) the Dempster Uniform Density Method, currently in use for BSPs calculation, using Dempster density data, (2) the Personalized Method using full-description of the thorax based on 3D reconstruction of the rib cage and spine and (3) the Improved Uniform Density Method using a uniform thorax density resulting from the Personalized Method. For 10 participants, comparison was made between the body mass obtained from a force-plate and the body mass computed with each of the three methods. The Dempster Uniform Density Method presented a mean error of 4.8% in the total body mass compared to the force-plate vs 0.2% for the Personalized Method and 0.4% for the Improved Uniform Density Method. The adjusted thorax density found from the 3D reconstruction was 0.74g/cm(3) for men and 0.73g/cm(3) for women instead of the one provided by Dempster (0.92g/cm(3)), leading to a better estimate of the thorax mass and body mass.

Aims: To study socioeconomic status (SES) and living conditions (LC) as risk factors for latent tuberculosis infection (LTBI) and their impact on QuantiFERON-TB gold (QFT-G) and tuberculin skin test (TST) outcome for determining a better diagnostic test for LTBI in the malnourished tribal population of Melghat. Settings and Design: Six hundred sixty nine participants matching the inclusion criteria were recruited from 10 tribal villages of Melghat region, India. Subjects and Methods: Complete information related to various risk factors and test outcome was obtained on 398 participants, which was analyzed as per predefined conceptual framework. Factors were classified based on their relevance either at individual or household level, and subsequently based on the possibility of intervention. Data were partitioned into concordant and discordant sets depending on test agreement. Results: In concordant set, the two tests revealed that LTBI was significantly associated with smoking (adjusted odds ratio [aOR]: 2.64 [95% confidence interval [CI]: 1.03–6.79]), tobacco usage (aOR: 2.74 [95% CI: 1.50–4.99]), and malnourishment (aOR: 1.97 [95% CI: 1.12–3.48]) after basic adjustment. Inclusion of latent variable SES and LC in the model has mediating effect on the association of above factors with LTBI. Further, the association of SES and LC with LTBI in concordant set was unaltered in presence of other cofactors. From discordant set, results of QFT-G corroborated with that of concordant set. Conclusions: Poor SES and LC can be considered as strong risk factors linked with LTBI as compared to malnourishment, which is often targeted in such communities. Further, our study showed QFT-G test as a reliable tool in screening of LTBI in the tribal population of Melghat, India. PMID:27578928
Full Text Available Introduction: Women living with HIV (WLWH are reportedly at increased risk of invasive cervical cancer (ICC. WLWH in Denmark attend the National ICC screening program less often than women in the general population. We aimed to estimate the incidence of cervical dysplasia and ICC in WLWH in Denmark. Methods: We studied a nationwide cohort of WLWH and a cohort of age-matched females from the general population in the period 1999–2010. Pathology samples were obtained from The Danish Pathology Data Bank containing nationwide records of all pathology specimens. The cumulative incidence and hazard ratios (HRs for time from inclusion to first cervical intraepithelial neoplasia (CIN/ICC and time from first normal cervical cytology to first CIN/ICC were estimated. Sensitivity analyses were performed to include prior screening outcome, screening intensity and treatment of CIN/ICC in the interpretation of results. Results: We followed 1,143 WLWH and 17,145 controls with no prior history of ICC for 9,509 and 157,362 person-years. Compared to controls, the overall incidence of CIN1 or worse (CIN1+, CIN2+ and CIN3+ was higher in WLWH and predicted by young age and CD4 count <200 cells/µL. In women with normal baseline cytology, incidences of CIN1+ and CIN2+ were higher in WLWH. However, incidences were comparable between WLWH and controls adherent to the National ICC screening program. Conclusions: Overall, WLWH develop more cervical disease than controls. However, incidences of CIN are comparable amongst WLWH and controls adherent to the National ICC screening program and with a normal baseline cytology.

Nine adolescent females were enrolled in a prenatal course that included the PREP for Effective Family Living Program (the treatment group). Two comparison groups were utilized in this study; one attended the prenatal group without the PREP program, and the second did not attend either the prenatal course or the PREP program. The Coopersmith Self-Esteem Inventory and the Attitude Toward the Freedom of Children Scale (a parental attitude scale) was administered to all participants. No significant difference was found among the three groups in terms of self-concept. A significant difference was found among the three groups in terms of parental attitudes, with the treatment group scoring higher on democratic parenting attitudes than did the two comparison groups.

Full Text Available Background: The Vestibular Disorders Activities of Daily Living Scale (VADL is considered an important subjective assessment to evaluate patients suffering from dizziness and imbalance. Although frequently used, its metric characteristics still require further investigation. Objective: This paper aims to analyze the psychometric properties of the Brazilian version of the VADL in an elderly population. Method: The sample comprises patients (≥65 years old with chronic dizziness resulting from vestibular disorders. For discriminant analysis, patients were compared to healthy subjects. All subjects answered the VADL-Brazil by interview. To examine the VADL validity, patients filled out the Dizziness Handicap Inventory (DHI and the ABC scale and were tested on the Dynamic Gait Index (DGI. To evaluate the VADL responsiveness, 20 patients were submitted to rehabilitation. Results: Patients (n=140 had a VADL total score of 4.1±1.6 points. Healthy subjects scored significantly less than patients in all the subscales and in the VADL total score. The VADL-Brazil was weakly correlated with the DHI and moderately to the ABC scale and the DGI. Instead of the original 3 subscales, factor analysis resulted in 6 factors. The VADL was capable of detecting changes after rehabilitation, which means that the instrument has responsiveness. Conclusions: This study provided more data about the psychometric properties and usefulness of the VADL-Brazil. The use of such a reliable and valid instrument increases the knowledge about disability in patients with vestibular disorders.

Full Text Available The aim of this study is to establish a risk appraisal model for GDM by identifying modifiable factors that can help predict the risk of GDM in a large population of 2194 women living in Spain. They were recruited between 2009-2010 when screening for GDM was performed. Participants completed a questionnaire on socio-demographic, anthropomorphic and behavioral characteristics, and reproductive and medical history. A total of 213 (9.7% women were diagnosed as having GDM. Age, pregestational body weight (BW and body mass index (BMI, and number of events of medical, obstetric and family history were significantly associated with GDM. After logistic regression model, biscuits and pastries intake 30 minutes/day, and 30 minutes/day of sports at least 2 days/week, compared with opposite consumption, was associated with less GDM risk. Our study identified several pregestational modifiable lifestyle risk factors associated with an increase in the risk of developing GDM. This may represent a promising approach for the prevention of GDM and subsequent complications. Further intervention studies are needed to evaluate if this appraisal model of risk calculation can be useful for prevention and treatment of GDM.

As part of Villanova's Living with a Red Dwarf program, we have obtained UV, X-ray and optical data of the Population II red dwarf -- Kapteyn's Star. Kapteyn's Star is noteworthy for its large proper motions and high RV of ~+245 km s^-1. As the nearest Pop II red dwarf, it serves as an old age anchor for calibrating Activity/Irradiance-Rotation-Age relations, and an important test bed for stellar dynamos and the resulting X-ray -- UV emissions of slowly rotating, near-fully convective red dwarf stars. Adding to the notoriety, Kapteyn's Star has recently been reported to host two super-Earth candidates, one of which (Kapteyn b) is orbiting within the habitable zone (Anglada-Escude et al. 2014a, 2015). However, Robertson et al. (2015) questioned the planet's existence since its orbital period may be an artifact of activity, related to the star's rotation period. Because of its large Doppler-shift, measures of the important, chromospheric H I Lyman-alpha 1215.67A emission line can be reliably made, because it is...

The accommodation of photosynthetic organisms to adverse conditions, such as pH changes in the aquatic environment, and their response to aquatic pollutants is essential to develop future biosensors. The present study reports the ability of both Cr(VI)-sensitive and tolerant Dyctiosphaerium chlorelloides strains to live in aqueous solutions highly contaminated with hexavalent chromium under varying ranges of pH, by the determination of chromium toxic effects on these strains. Studies of cell growth, photosynthetic quantum yield and gross photosynthesis rate show that both D. chlorelloides strains are able to survive in alkaline and moderately acidified (pH 4.25) aquatic environments. Below this pH value cell populations from both strains exposed for short periods of time to Cr(VI) showed alterations in the three parameters studied. There were no significant differences comparing the response of both strains at pH change in the culture medium. However, Cr(VI)-tolerant strain exhibits a better fit to maintain cell growth than Cr(VI)-sensitive strain when both were subjected to pH 4.25 in the culture medium. The absence of significant differences in photosynthetic activity results for both strains suggests that the lower sensitivity exhibited by Cr(VI)-tolerant strain would be due to cellular morphological changes rather than changes in cellular activity. © 2013 Published by Elsevier Inc.

The beneficial impact of walnuts on human health has been attributed to their unique chemical composition. In order to characterize the dietary walnut fingerprinting, spot urine samples from two sets of 195 (training) and 186 (validation) individuals were analyzed by an HPLC-q-ToF-MS untargeted metabolomics approach, selecting the most discriminating metabolites by multivariate data analysis (VIP ≥ 1.5). Stepwise logistic regression analysis was used to design a multimetabolite prediction biomarker model. The global performance of the model and each included metabolite in it was evaluated by receiver operating characteristic curves, using the area under the curve (AUC) values. Dietary exposure to walnuts was characterized by 18 metabolites, including markers of fatty acid metabolism, ellagitannin-derived microbial compounds, and intermediate metabolites of the tryptophan/serotonin pathway. The predictive model of walnut exposure included at least one compound of each class. The AUC (95% CI) for the combined biomarker model was 93.4% (90.1-96.8%) in the training set and 90.2% (85.9-94.6%) in the validation set. The AUCs for individual metabolites were ≤85%. As far as we know, this is the first study proposing a combination of biomarkers of walnut exposure in a population under free-living conditions, as considered in epidemiological studies examining associations between diet and health outcomes.
Full Text Available Introduction: The high prevalence of overweight and obesity is a health problem in Cuba, and there is a lack of information on adolescents. The objective of the present study was to evaluate the relationship between excessive weight and adiposity with physical activity, hours of television (TV, and eating habits in adolescents.Material and methods: A total of 604 adolescents (12 years from Havana were studied. The variables analysed included, body mass index, body composition, history of obesity in infancy, physical activity, hours watching television, eating habits and dietary preferences. A descriptive and correlation analysis was performed. In the logistic regression analysis, excess weight and adiposity were used as dependent variables.Results: Excess body weight was more common in boys. There was high prevalence of excess adiposity, 49.8% in girls and 37.8% in boys. The boys (61.7% were more active than the girls (33.6%. Just under half (46.7% of the boys, and 55.9% of the girls spent more than 2 hours/day watching television, which increased to more than 75% for both sexes on Saturdays and Sunday. Making less than 5-6 meals/day doubled the risk of being overweight. Body overweight in infancy was also a risk factor. Not having breakfast increased the risk of adiposity by almost double.Conclusions: Excess weight, and particularly excess adiposity, may be considered a health problem in the adolescents studied. A very high consumption of sugar, an excessive time watching TV, and insufficient physical activity was observed.

Full Text Available This study evaluated the prevalence and severity of dental fluorosis and compared the reports from adolescents aged 12 to 18 years with those of their parents regarding the perceptions and concerns arising from this disease. The study was conducted in the cities of Viçosa and Sobral and the District of Rafael Arruda (Sobral, Ceará. A cross-sectional study was conducted from October 2010 to March 2011, with 891 students examined and 780 parents or guardians interviewed. Dental fluorosis was measured using the Dean's Index, and the Child's and Parent's Questionnaire about Teeth Appearance was used to assess the reports from parents and adolescents. A chi-squared test for trends was used to compare the opinions of parents and adolescents about fluorosis, and the agreement was measured using the weighted kappa. For the dichotomous variables, we used the unweighted kappa coefficient. The prevalence of fluorosis was 29.7%, but in the District of Rafael Arruda, evidence of very mild and mild fluorosis was found in 32.5% of the subjects, and moderate and severe fluorosis was found in 28.7%. There was poor agreement between the data reported by the adolescents and their parents or guardians regarding areas of concern and their perceived satisfaction with the appearance and color of their teeth. The prevalence of dental fluorosis was high in one of the communities studied, but the clinical diagnosis of this condition should not necessarily equate with concern and dissatisfaction with aesthetic appearances among teenagers and their parents.

To determine whether there were differences in presentation, imaging, and tumour markers between pediatric and adolescent gynaecology patients with adnexal masses managed expectantly and those managed surgically. We conducted a retrospective review of patients who presented to the pediatric and adolescent gynaecology service with adnexal masses between January 2003 and January 2006 at Toronto's Hospital for Sick Children. We used t tests, chi-square, and Pearson correlation tests for analysis. We identified 114 patients with an adnexal mass. Fifty-nine percent had surgery (laparotomy 41.8%, laparoscopy 58.2%) and 41% were managed conservatively. The mean age of patients was 12.7 years (range 7 days to 18 years) and there was no difference in age between management groups (P = 0.59). The most common presenting symptom was abdominal pain (72.8%). Increased abdominal girth was found only in the surgical group (P mass was the only feature on imaging that differed between groups (11.1 cm surgical vs. 5.3 cm observed, P masses, and malignant masses were larger than benign masses (16.1 cm vs. 10.5 cm, P masses resolved, with or without hormonal suppression. Larger masses and masses associated with increased abdominal girth or abnormal tumour markers were more likely to be managed by surgical intervention. Surgically managed patients had more investigations. Forty-one percent of masses in patients referred to pediatric and adolescent gynaecology specialists resolved with expectant management.

500 years of mercury (Hg) mining in the town of Idrija has caused severe pollution in Idrija and its surroundings. Following the closure of the mine in 1995, the environment remains contaminated with Hg. Sources of elemental-, inorganic- and methyl Hg exposure were identified, potential environmental level of exposure to Hg was evaluated and actual internal exposure to Hg was assessed in selected susceptible population groups comprising school-age children and pregnant women living in Idrija and in control groups from rural and urban environments. The study of pregnant women (n=31) was conducted between 2003 and 2008, and the study of school-age children (n=176) in 2008. Potential interaction of Hg with selenium (Se) in plasma was assessed in both study populations, while in pregnant women antioxidative enzyme activity (glutathione peroxidase, superoxide dismutase and catalase) in erythrocytes of maternal and cord blood was also assessed. Actual exposure to Hg as indicated by levels of Hg in children's blood (geometric mean (GM) 0.92µg/L), mother's blood (GM 1.86µg/L), children's urine (GM 1.08µg/g crea.), mother's urine (GM 2.51µg/L), children's hair (GM 241ng/g) and mother's hair (GM 251ng/g) was higher in the two study groups from Idrija than in the control groups from rural areas, but was still at the level of a "normal" population and reflects mainly exposure to elemental Hg (Hg°) from dental amalgam and, to a certain extent atmospheric Hg°. Furthermore, the internal doses of Hg received during pregnancy did not decrease the bioavailability of Se. Based on observation in children, the increase in Se protein expression is suggested to be a consequence of moderately elevated exposure to Hg°. The observed changes in activity of antioxidative enzymes, as biomarkers of oxidative stress, appear to be mainly associated with pregnancy per se and not with an increased exposure to Hg. In view of the continuing increased potential for Hg exposure and the low
Low genetic diversity and local adaptive divergence of Dracaena cambodiana (Liliaceae) populations associated with historical population bottlenecks and natural selection: an endangered long-lived tree endemic to Hainan Island, China.
Zheng, D-J; Xie, L-S; Zhu, J-H; Zhang, Z-L
Historical population bottlenecks and natural selection have important effects on the current genetic diversity and structure of long-lived trees. Dracaena cambodiana is an endangered, long-lived tree endemic to Hainan Island, China. Our field investigations showed that only 10 populations remain on Hainan Island and that almost all have been seriously isolated and grow in distinct habitats. A considerable amount of genetic variation at the species level, but little variation at the population level, and a high level of genetic differentiation among the populations with limited gene flow in D. cambodiana were detected using inter-simple sequence repeat (ISSR) and random amplified polymorphic DNA (RAPD) analyses. No significant correlation was found between genetic diversity and actual population size, as the genetic diversities were similar regardless of population size. The Mantel test revealed that there was no correlation between genetic and geographic distances among the 10 populations. The UPGMA, PCoA and Bayesian analyses showed that local adaptive divergence has occurred among the D. cambodiana populations, which was further supported by habitat-private fragments. We suggest that the current genetic diversity and population differentiation of D. cambodiana resulted from historical population bottlenecks and natural selection followed by historical isolation. However, the lack of natural regeneration of D. cambodiana indicates that former local adaptations with low genetic diversity may have been genetically weak and are unable to adapt to the current ecological environments.

Full Text Available BACKGROUND: One of the rationales behind using strength training in the treatment of adolescents with Patellofemoral Pain (PFP is that reduced strength of the lower extremity is a risk factor for PFP and a common deficit. This rationale is based on research conducted on adolescents >15 years of age but has never been investigated among young adolescents with PFP. OBJECTIVES: To compare isometric muscle strength of the lower extremity among adolescents with PFP compared to age- and gender-matched pain-free adolescents. METHODS: In 2011 a population-based cohort (APA2011-cohort consisting of 768 adolescents aged 12-15 years from 8 local schools was formed. In September 2012, all adolescents who reported knee pain in September 2011 were offered a clinical examination if they still had knee pain. From these, 20 adolescents (16 females were diagnosed with PFP. Pain-free adolescents from the APA2011-cohort (n = 20 were recruited on random basis as age- and gender-matched pairs. Primary outcome was isometric knee extension strength normalized to body weight (%BW and blinded towards subject information. Secondary outcomes included knee flexion, hip abduction/adduction and hip internal/external rotation strength. Demographic data included Knee Injury and Osteoarthritis Outcome Score (KOOS and symptom duration. RESULTS: Adolescents with PFP reported long symptom duration and significantly worse KOOS scores compared to pain-free adolescents. There were no significant differences in isometric knee extension strength (Δ0.3% BW, p = 0.97, isometric knee flexion strength (Δ0.4% BW, p = 0.84 or different measures of hip strength (Δ0.4 to 1.1% BW, p>0.35. CONCLUSION: Young symptomatic adolescents with PFP between 12 and 16 years of age did not have decreased isometric muscle strength of the knee and hip. These results question the rationale of targeting strength deficits in the treatment of adolescents with PFP. However, strength training may
Full Text Available AIM: To investigate the factors predicting adolescent visits to practitioners of complementary and alternative medicine (CAM. METHODS: A longitudinal cohort study conducted in an adolescent total population in Central Norway (The Nord-Trøndelag Health Studies (HUNT. In Young-HUNT 1, all inhabitants aged 13 to 19 years (N = 8944, 89% response rate were invited to participate, and the youngest group (13 to 15 year olds was surveyed again 4 years later (Young-HUNT 2, N = 2429, 82% response rate. The participants completed a comprehensive questionnaire on health and life style which included a question regarding visits to a CAM practitioner in the last 12 months. RESULTS: One in eleven (8.7%, 95%CI 7.6-9.8% had visited a CAM practitioner, an increase of 26% in 4 years (1.8% points. The final multivariable analysis predicted increased odds of an adolescent becoming a CAM visitor four years later (p<0.05 if she or he had previously visited a CAM practitioner (adjOR 3.4, had musculoskeletal pain (adjOR 1.5, had migraine (adjOR 2.3, used asthma medicines (adjOR 1.8 or suffered from another disease lasting more than three months (adjOR 2.1. Being male predicted reduced odds of visiting a CAM practitioner in the future (adjOR 0.6. CONCLUSION: We can conclude from this study that future visits to a CAM practitioner are predicted by both predisposing factors (being female, having visited a CAM practitioner previously and medical need factors (having had musculoskeletal pain, migraine, used asthma medicines or experienced another disease lasting more than three months. None of the specific variables associated with CAM visits were predictive for CAM visits four years later.
Full Text Available OBJECTIVE: Visceral fat (VF increases cardiometabolic risk more than fat stored subcutaneously. Here, we investigated how well routine clinical measures of adiposity, namely body mass index (BMI and waist circumference (waist, predict VF and subcutaneous fat (SF in a large population-based sample of adolescents. As body-fat distribution differs between males and females, we performed these analyses separately in each sex. DESIGN AND METHODS: VF and SF were measured by magnetic resonance imaging in 1,002 adolescents (482 males, age 12-18 years. Relationships of BMI and waist with VF and SF were tested in multivariable analyses, which adjusted for potentially confounding effects of age and height. RESULTS: In both males and females, BMI and waist were highly correlated with VF and SF, and explained 55-76% of their total variance. When VF was adjusted for SF, however, BMI and waist explained, respectively, only 0% and 4% of VF variance in males, and 4% and 11% of VF variance in females. In contrast, when SF was adjusted for VF, BMI and waist explained, respectively, 36% and 21% of SF variance in males, and 48% and 23% of SF variance in females. These relationships were similar during early and late puberty. CONCLUSIONS AND RELEVANCE: During adolescence, routine clinical measures of adiposity predict well SF but not VF. This holds for both sexes and throughout puberty. Further longitudinal studies are required to assess how well these measures predict changes of VF and SF over time. Given the clinical importance of VF, development of cost-effective imaging techniques and/or robust biomarkers of VF accumulation that would be suitable in everyday clinical practice is warranted.

Developmental changes in children's fears with a particular focus on fears of nuclear war were studied in a sample of 1243 Australian children and adolescents aged between 4-19 years. The average number of fears reported per child was 9.3. Females reported significantly more fears than males. Developmental changes also were apparent with animal and supernatural fears in the youngest age group giving way to social fears and fear of war in the older age brackets. An average of 67.4% of the sample expressed a fear of nuclear war. The implications of this finding for parents and educators are discussed.

Full Text Available Introduction: Worldwide, HIV-related mortality among adolescents living with HIV (ALHIV increased by 50% from 2005 to 2012 and is attributed in part to a lack of support for adolescent retention to care and adherence to antiretroviral therapy (ART. This vulnerability reinforces the need to better understand incomplete ART adherence among ALHIV, particularly in sub-Saharan Africa, where the majority of the world's 2.1 million ALHIV reside. Methods: From December 2011 to February 2012, we conducted in-depth interviews with 32 ALHIV (aged 15 to 18 and 23 of their adult caregivers in the Copperbelt Province of Zambia. Interviews were transcribed and translated. An iterative qualitative process was used to code and analyze the data and main themes were summarized regarding the barriers to and facilitators of ART adherence. Results: More than a quarter of ALHIV reported missing a day or more of ART (ranging from one day to six months. Barriers to ART adherence included fear of disclosure and anticipated stigma. Few youth were willing to take their drugs outside of the home, which led to missed doses of ART. Similarly, families tended to manage HIV within the home only. As a result, although caregivers and families were often the greatest source of emotional and instrumental support, they coped with HIV in isolation of other potential support from their communities, schools or churches. Factors that supported ART adherence included attending clinic-sponsored youth groups, wanting to maintain one's health and using phone and clock alarms. Involvement of adult caregivers in HIV management varied greatly and was often based on the age and health status of the youth. Some caregivers struggled with letting the adolescents assume responsibility for their medication, and ALHIV had few self-management skills and tools to help them regularly take ART. Conclusions: These data highlight the importance of families and home environments in supporting adherence to

Little is known about the factors which might influence the adherence to a Mediterranean diet in non-Mediterranean European countries. Thus, the main purpose of this study was to determine the associations between socioeconomic, psychological, and physical factors on a Mediterranean diet. In this cross-sectional study, participants were 14-18-year-old adolescents (N = 3071) from two non-Mediterranean countries: Lithuania (N = 1863) and Serbia (N = 1208). The dependent variable was Mediterranean diet, and was assessed with the Mediterranean Diet Quality Index for children and adolescents questionnaire. Independent variables were gender, body-mass index, self-rated health, socioeconomic status, psychological distress, physical activity, and sedentary behavior. The associations between dependent and independent variables were analyzed by using logistic regression. Results showed that higher adherence to a Mediterranean diet was associated with higher self-rated health, socioeconomic status, and physical activity, yet low adherence to a Mediterranean diet was associated with being female, having higher body-mass index, psychological distress, and sedentary behavior. Our findings suggest that future studies need to explore associations between lifestyle habits-especially in target populations, such as primary and secondary school students.

Numerous studies have shown an alarming prevalence of depression, anxiety, and behavior disorders in youth. Thus, prevention of psychological problems in this population becomes crucial. According to the World Health Organization (1), prevention should also include the promotion and development of the individual's strengths in order to reduce vulnerability to suffering from mental disorders. In addition, other key elements of prevention are the reach, adoption, implementation, and maintenance of interventions. The information and communication technologies, especially the Internet, have much to offer in terms of the prevention and promotion of positive mental health in adolescents. This paper reviews these fields of research-prevention, positive psychology, Internet, and adolescents-and discusses the potential of positive interventions delivered over the Internet as effective and sustainable health promotion tools. The paper provides a brief description of the systems developed so far and a summary of selected features of the studies detected in the literature review. The overall conclusions are that there is a need for more controlled studies with long-term follow-ups, the interventions should be designed considering the specific features of the target users and the specific contexts where the interventions will be delivered, and they could be enhanced by the use of other technologies, such as smartphones, sensors, or social networks.

Full Text Available Introduction: The availability of specialized HIV services is limited in rural areas of sub-Saharan Africa where the need is the greatest. Where HIV services are available, people living with HIV (PLHIV must overcome large geographic, economic and social barriers to access healthcare. The objective of this study was to understand the unique barriers PLHIV face when accessing healthcare compared with those not living with HIV in a rural area of sub-Saharan Africa with limited availability of healthcare infrastructure. Methods: We conducted a population-based cross-sectional study of 447 heads of household on Bugala Island, Uganda. Multiple linear regression models were used to compare travel time, cost and distance to access healthcare, and log binomial models were used to test for associations between HIV status and access to nearby health services. Results: PLHIV travelled an additional 1.9 km (95% CI (0.6, 3.2 km, p=0.004 to access healthcare compared with those not living with HIV, and they were 56% less likely to access healthcare at the nearest health facility to their residence, so long as that facility lacked antiretroviral therapy (ART services (aRR=0.44, 95% CI (0.24 to 0.83, p=0.011. We found no evidence that PLHIV travelled further for care if the nearest facility supplies ART services (aRR=0.95, 95% CI (0.86 to 1.05, p=0.328. Among those who reported uptake of care at one of two facilities on the island that provides ART (81% of PLHIV and 68% of HIV-negative individuals, PLHIV tended to seek care at a higher tiered facility that provides ART, even when this facility was not their closest facility (30% of PLHIV travelled further than the closest ART facility compared with 16% of HIV-negative individuals, and travelled an additional 2.2 km (p=0.001 to access that facility, relative to HIV-negative individuals (aRR=1.91, 95% CI (1.00 to 3.65, p=0.05. Among PLHIV, residential distance was associated with access to facilities providing

Body composition was determined by bioelectric impedance analysis (BIA. The homeostatic model assessment of IR (HOMA-IR, based on fasting glucose and insulin concentrations, was used to estimate IR. Stepwise linear regression analyses were performed to predict HOMA-IR based on the six selected measures, while controlling for age.Results: The stepwise regression retained both waist circumference (WC and percentage of body fat (BF%. Notably, BMI was not retained. WC was a stronger predictor of HOMA-IR than BMI was. A regression model using solely WC performed best among the obese II group, while a model using solely BF% performed best among the lean group. Receiver operator characteristic curves showed the WC and BF% model to be more sensitive in detecting IR than BMI, but with less specificity.Conclusion: WC combined with BF% was the best predictor of HOMA-IR. This finding can be attributed partly to the ability of BF% to model HOMA-IR among leaner participants and to the ability of WC to model HOMA-IR among participants who are more obese. BMI was comparatively weak in predicting IR, suggesting that assessments that are more comprehensive and include body composition analysis could increase detection of IR during adolescence, especially among those who are lean, yet insulin-resistant.Keywords: BMI, bioelectrical impedance

Patterns of nutritional behaviours shaped in childhood and during the period of adolescents are mostly continued in adult life, and on these patterns, to a great degree, depends the risk of development of many chronic diseases. The aim of this study was to assess the relationship between dietary habits and body image perception among Polish adolescents and young adults. The study group covered 14,511 adolescents/young adults: 10,081 children attending high schools and secondary schools, and 4,428 university students. More than 87% of schoolchildren and students admitted that that they snacked between meals everyday, and 1/3 of them mentioned that they consumed meals at night. As many as 41.40% of schoolchildren, and 46.70% of students experienced the feeling of overeating at least several times a week. Analysis of the respondents BMI showed that in the group of students there were considerably more respondents obese or overweight, compared to the group of schoolchildren. Fear of gaining weight was mentioned by 9.90% of respondents, including 6.90% of those with normal body structure, 1.40% with underweight or overweight, and 0.40% of those obese. As many as 54.60% of the total number of respondents described their body structure as remaining within the normal, 23.7% - as slim, 13.9% reported that they were overweight, 6% - thin, while 1.7% considered themselves as obese. A comprehensive analysis of the data available, including attempts at dieting or gaining weight, indicated that approximately ¾ of obese respondents had undertaken attempts in the past to reduce their body weight. The importance of physical activity and healthy eating habits should be given due attention not only to prevent obesity but also other eating disorder.

Far from being unthinking energies or irrational impulses that control or push people around, emotions are intricately connected to the way people perceive, understand, and think about the world. As such, emotions are also an inextricable part of people's moral lives. As people go about making moral judgments and decisions, they do not merely…

Full Text Available BACKGROUND: Certain population groups have been rendered vulnerable in Chad because of displacement of more than 200,000 people over the last three years as a result of mass violence against civilians in the east of the country. The objective of the study was to assess mortality and nutritional patterns among displaced and non-displaced population living in camps, villages and a town in the Ouddaï and Salamat regions of Chad. METHODOLOGY: Between May and October 2007, two stage, 30-cluster household surveys were conducted among 43,900 internally displaced persons (IDPs living in camps in Ouaddai region (n = 898 households, among 19,400 non-displaced persons (NDPs living in 42 villages in Ouaddai region (n = 900 households and among 17,000 NDPs living in a small town in Salamat region (n = 901 households. Data collection included anthropometric measurements, measles vaccination rates and retrospective mortality. Crude mortality rate (CMR, mortality rate among children younger than 5 years (U5MR, causes of death and the prevalence of wasting (weight-for-height z score <-2 among children aged 6 to 59 months were the main outcome measures. CONCLUSIONS: The CMR among the 4902 IDPs in Gozbeida camps, 4477 NDPs living in a village and 4073 NDPs living in a town surveyed was 1.8 (95% CI, 1.2-2.8, 0.3 (95% CI, 0.2-0.4, 0.3 (95% CI, 0.2-0.5 per 10,000 per day, respectively. The U5MR in a camp (n = 904, a village (n = 956 and a town (n = 901 was 4.1 (95% CI, 2.1-7.7, 0.5 (95% CI, 0.3-0.9 and 0.7 (95% CI, 0.4-1.4 per 10,000 per day, respectively. Diarrhoea was reported to be the main cause of death. Acute malnutrition rates (according to the WHO definition among 904 IDP children, 956 NDPs children living in a village, 901 NDP children living in a town aged 6 to 59 months were 20.6% (95% CI, 17.9%-23.3%, 16.4% (95% CI, 14.0%-18.8% and 10.1% (95% CI, 8.1%-12.2% respectively. The study found a high mortality rate among IDPs and an elevated prevalence of

Optimal dosing of propofol to maintain appropriate anesthetic depth is challenging in severely obese (SO) adolescents. We previously reported that total body weight (TBW) is predictive of propofol clearance. This study was aimed at characterizing pharmacokinetics (PK) and pharmacodynamics (PD) of propofol in SO adolescents, using bispectral index (BIS), and toward developing PK/PD model-based dosing guidelines. A prospective PK/PD study was conducted in 26 SO children and adolescents aged 9-18 years (body mass index 31-69 kg·m(-2)), undergoing surgery with intravenous propofol anesthesia clinically titrated by providers blinded to BIS. BIS data and propofol infusion schemes were recorded. Venous blood samples collected during and after propofol infusion were assayed for propofol concentrations. A propofol PK/PD model was developed using NONMEM and model-based simulations were performed to determine propofol dosing regimens targeting BIS of 50 ± 10. A three-compartment PK model linked to a sigmoidal inhibitory Emax PD model by a first-order rate constant, adequately described the propofol concentration (n = 375) and BIS (n = 3334) data. TBW was the most predictive covariate for propofol clearance [CL (l·min(-1) ) = 1.65 × (TBW/70)(0.75)]. An effect-site propofol concentration of 3.19 μg·ml(-1) was estimated for half-maximal effect, with no identifiable predictive covariates. The proposed maintenance dosing regimen targeted to a BIS of 50 ± 10, based on our PK/PD model, was able to predict desired propofol concentrations and BIS in a representative obese teen when used in conjunction with accepted PK/PD models for children/obese adults (PK:Eleveld/PD: Cortinez), further supporting evidence for the dosing based on TBW. This is the first study to describe the PK/PD of propofol in SO adolescents. The proposed maintenance dosing regimen for propofol uses TBW in an allometric function as a dosing scalar, with an exponent of 0.75. Our results suggest no relevant
