The aim of this study was to examine the associations of objectively measured physical activity (PA) and cardiorespiratory fitness (CRF) with different continuous metabolic syndrome (MetS) scores in adolescents. A cross-sectional sub-sample of 202 adolescents (99 girls), aged 13-17 years, were selected from the AFINOS Study. Body mass index, sum of 6 skindfold, waist circumference, systolic and diastolic blood pressure, insulin, glucose, triacylglycerol, and HDL-cholesterol levels were determined. Moderate PA (MPA), vigorous PA (VPA) and moderate to vigorous PA (MVPA) were assessed by the ActiGraph accelerometer for 7 consecutive days and CRF was estimated by the 20-m shuttle run test. Three continuous MetS scores were calculated according to the methodology of the Corpus Christi Child Heart Study (CCCHS), the Aerobic Center Longitudinal Study (ACLS), and the European Youth Heart Study (EYHS). VPA and MVPA were significantly related with CRF. Only CRF, and not patterns of PA, was inversely and independently associated with the three MetS scores although with different magnitudes (ranged: beta = 0.22 to 0.36, p < 0.05). A significant VPA x CRF interaction (p = 0.011) was found using the ACLS MetS score. Trends across VPA-CRF groups were significantly different with ACLS and EYHS (p = 0.002 and p = 0.006, respectively), but not with CCCHS (p = 0.313) continuous MetS scores. These findings support the key role of CRF on the MetS and the relevance of PA, especially VPA, to provide CRF in adolescents. A unified pediatric definition of MetS might minimize the discrepancies among studies.

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

El rendimiento académico se valoró en los estudios AFINOS y UP&DOWN con las notas de Matemáticas, Lengua y la media de Lengua y Matemáticas. Resultados: en el estudio AVENA encontramos diferencias en la habilidad verbal entre las chicas a las que no les gustaba la educación física y sus compañeros (P = 0,033). En el estudio AFINOS los chicos a los que no les gustaba la educación física tenían mejores notas en Lengua que sus compañeros (P = 0,024). En el estudio UP&DOWN las chicas a las que no les gustaba la educación física obtuvieron mejores resultados en Lengua y en la media de Lengua y Matemáticas (P < 0,001).
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.

Full Text Available The aims of the present study were: (i describe patterns of sedentary behavior in Spanish adolescents; and (ii determine the proportion of adolescents that do not meet the public health recommendations for sedentary behavior. This study comprised 1,724 Spanish adolescents (882 girls, aged 13 to 16 years. Patterns of sedentary behavior (TV viewing, use of computer games, console games and surfing the Internet were assessed using the HELENA sedentary behavior questionnaire. The total proportion of adolescents watching TV, using computer and console games, and surfing the internet for more than two hours daily was 24%, 9%, 7%, and 17%, respectively, on weekdays, and 50%, 22%, 16%, and 35%, respectively, on weekends. Over 63% of the adolescents from the study did not meet the recommendation for sedentary behavior (Los objetivos del estudio son: (i describir los patrones de comportamiento sedentario en adolescentes españoles y (ii establecer cuántos de ellos no cumplen las recomendaciones de salud pública sobre comportamiento sedentario. Participaron 1.724 adolescentes españoles (882 chicas entre 13 y 16 años. Los patrones de comportamiento sedentario (ver la televisión, juegos de ordenador, videojuegos y navegar en Internet fueron evaluados a través del cuestionario HELENA. La proporción total de adolescentes que ven la TV, usan juegos de ordenador o de consola y navegan en Internet durante > 2h los días de diario fue del 24%, 9%, 7% y 17%, respectivamente. Durante los fines de semana, la proporción fue del 50%, 22%, 16% y 35%. Más del 63% del total de la muestra no cumplen las recomendaciones de tiempo sedentario total < 2 horas durante los días de diario y el 87% no lo hace en días del fin de semana. Dado que las conductas sedentarias podrían ser relevantes en la salud de los adolescentes, las intervenciones de salud pública son necesarias en España.
Preliminary evidence of physical activity levels measured by accelerometer in Spanish adolescents: The AFINOS Study Evidencia preliminar de los niveles de actividad física medidos mediante un acelerómetro en adolescentes españoles: Estudio AFINOS
Full Text Available Background: It is necessary to know the levels of physical activity (PA for a better understanding of the development of chronic diseases in youth. The aim of this study was to assess levels of total PA and time spent in different PAintensities in Spanish adolescents by accelerometer. Methods: A sub-sample of 214 healthy Spanish adolescents (107 females, aged 13-16 years, enrolled in the AFINOS Study was selected for this study. Participants wore the ActiGraph GT1M accelerometer for 7 consecutive days. Total PA and time spent in sedentary, light, moderate, vigorous, and moderate to vigorous physical activity (MVPA was estimated using the accelerometer. Adiposity was measured in the sample using sum of 6 skinfoldthickness, waist circumference and BMI. Results: Adolescent boys were engaged in higher levels of total PA, moderate PA, vigorous PA and MVPA than adolescent girls, whereas girls were engaged in higher levels of light PA. Differences between age groups showed that the 15-16 years group did more total PA (P = 0.008 than the 13-14 years group. Adolescents with highest levels of body fat were less active and spent less time in vigorous PA and MVPA than adolescents with less body fat. Among the current sample, 71.1% of the adolescents (82.2% adolescent boys and 60.7% adolescent girls reached the recommendation of ≥ 60 min in MVPA. Conclusions: Although these findings suggest that Spanish adolescents have similar PA levels than other European adolescents, further cross-sectional and longitudinal studies must assess PA levels in free-living conditions in Spanish children and adolescents using objective methods such as accelerometers, heart rate monitors and pedometers.Antecedentes: Para comprender mejor el desarrollo de las enfermedades crónicas en los jóvenes resulta necesario conocer los niveles de actividad física (AF que realizan.

Gender-specific influence of health behaviors on academic performance in Spanish adolescents: the AFINOS study Rol del género en la influencia de las conductas saludables sobre el rendimiento académico en adolescentes españoles: el estudio AFINOS
Full Text Available Introduction: New paradigms based on the multifactorial etiology of chronic diseases and behavioral outcomes suggest that a combination of health behaviors may have more impact on the outcome of interest than any single factor. Objective: To examine the independent and combined influence of four health behaviors on school performance in Spanish adolescents. Methods: A total of 1825 Spanish adolescents reported their grades in Language and Literature (LL and Math. Body mass index, family structure and school-related factors (attitude to school, need to repeat > 1-yr and absenteeism were self-reported. Adolescents were dichotomized as healthy or unhealthy based on meeting or not meeting lifestyle recommendations on physical activity, TV viewing, sleep and fruit intake. Each adolescent was also scored according to the number of healthy recommendations fulfilled. Results: In boys, there were no associations between health behaviors and academic performance. Good academic performance in girls was associated with physical activity (P Introducción: Los nuevos paradigmas basados en la etiología multifactorial de las enfermedades crónicas y los resultados en el comportamiento sugieren que la combinación de comportamientos saludables puede tener un impacto más positivo en algún resultado de interés que cualquier otro factor aislado.

Objetivos: Este estudio compara la adherencia a las recomendaciones nutricionales de adolescentes inmigrantes y españoles residentes en la Comunidad de Madrid, España. Se comparó el consumo de ocho grupos principales de alimentos (verduras, frutas, pan/cereales, carne, huevos, pescado, legumbres, leche/derivados lácteos) incluyendo el consumo excesivo y deficiente de huevos, carne y pescado. También fue valorado el consumo excesivo de dulces y bebidas azucaradas. Posteriormente se analizó la influencia del tiempo de residencia en España sobre los mencionados hábitos de dieta. Material y método: Se llevó a cabo un estudio transversal en el que fueron recogidos datos auto-reportados durante el periodo comprendido entre Noviembre 2007 y Febrero 2008. Se obtuvo una muestra representativa de adolescentes con edades comprendidas entre 13 y 17 años (n=2081, 1055 mujeres) residentes en la Comunidad de Madrid. Los participantes pertenecían a centros de enseñanza secundaria seleccionados aleatoriamente según la distribución geográfica de los adolescentes en la región. Resultados: Los inmigrantes adolescentes presentaron una mayor probabilidad de no cumplir las recomendaciones nutricionales para el consume de carne, pescado, legumbres, pan/cereales y leche/derivados, de consumir una cantidad insuficiente de pescado y más dulces y bebidas azucaradas que sus compañeros españoles. Los adolescentes españoles mostraron una mayor probabilidad de no cumplir con la recomendación establecida para verduras. El tiempo de residencia afectó débilmente los hábitos de dieta, asociando aspectos tanto positivos como negativos. Conclusiones: La probabilidad de no cumplir las recomendaciones nutricionales fue mayor entre los adolescentes inmigrantes con excepción del consumo de frutas y verduras.

Objetivos: Este estudio fue diseñado para comparar el riesgo de trastornos de conducta alimentaria (TCA) entre adolescentes nativos e inmigrantes residentes en Madrid, así como para determinar la posible influencia del tiempo de residencia en el riesgo de los inmigrantes. Métodos: Se llevó a cabo un estudio transversal durante el periodo comprendido entre noviembre 2007 y febrero 2008 sobre una muestra representativa de adolescentes residentes en Madrid, con edades de entre 13 y 17 años (n = 2.077, 1.052 mujeres). Los datos se recogieron usando la versión española del cuestionario SCOFF para la detección de trastornos alimentarios. Otros factores considerados fueron el país de nacimiento, el tiempo de residencia y diversas variables biológicas, socio-demográficas, relativas a estilo de vida y la salud. Resultados: Según los tres modelos de regresión logística construidos, las mujeres adolescentes inmigrantes en conjunto mostraron un mayor riesgo de TCA (OR = 1,95; 95%CI 1,29-2,95; p = 0,001) que las nativas. Además, la probabilidad de sufrir TCA fue mayor entre las adolescentes inmigrantes con una residencia en España < 6 años que en las nativas (OR = 2,44; 95%CI 1,42-4,18; p = 0,001), mientras que no se encontraron diferencias entre las adolescentes nativas y las inmigrantes con un tiempo de residencia ≥6 años. No se observaron diferencias en el riesgo de TCA entre los adolescentes varones nativos y los inmigrantes, tanto en conjunto como según tiempo de residencia. Conclusiones: La condición de inmigrante y el tiempo de residencia son factores relevantes a la hora de considerar el riesgo de TCA en adolescentes residentes en Madrid.

Full Text Available INTRODUCTION: Adolescence is defined as the age group of 10-19 years. Adolescents suffer from psychosocial problems at one time or other during their development. Due to rapid industrialization and urbanization majority of young couple are employed and get less time to look after their children. Psychosocial problem and drug abuse are quite prevalent in this age group. AIM AND OBJECTIVE: To study the prevalence of psychosocial, emotional, behavioral problems, sexual orientation, drug abuse in adolescents (less than 18 years and compare with college students (18-22years of age. MATERIAL AND METHODS: The permission was taken from the head of the schools and colleges. A questionnaire was made and was distributed and information was collected. Sample 610 collected from school and 700 from college. RESULT: 580 and 669 students from schools and colleges respectively answered data correctly. 18% of school and 15% of college students have witnessed domestic violence in their families. Anxiety and stress was more in school going children than college (might be due to exams i.e.75%: 50% and 46%:41% respectively. Depression rate was almost equal among school and college i.e. 30%. Behavior of our children is influenced by their co-students, on assessing peer pressure it was found that 26-29%(1/3rd from school and college age group submit to peer pressure. In drug abuse alcohol intake was 12% and 19% in school and college group while prevalence of smoking was 4% and 12% respectively. Total number of students who were active in sexual activity was found to be 7.5% in schools and 14.6% in colleges. CONCLUSION: Adolescents constitute 1/5th of our population and prevalence of psychosocial problems along with drug abuse is increasing. With effective counseling by parents and teachers, sex education, stress reduction and improving familial environment, we can ensure a better future and improved adolescent health.

Theories on romantic relationship development posit a progression of involvement and intensity with age, relationship duration, and experience in romantic relationships. Using the National Longitudinal Study of Adolescent Health, this study tests these propositions by considering relationship type and patterns of relationships over the course of adolescence and their influence on relationship formation in young adulthood. Findings indicate that relationships become more exclusive, dyadic, of longer duration, and more emotionally and sexually intimate over the course of adolescence. Moreover, relationship experience in adolescence is associated with an increased likelihood of cohabitation and marriage in young adulthood. These findings indicate that instead of being trivial or fleeting, adolescent romantic relationships are an integral part of the social scaffolding on which young adult romantic relationships rest.

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

Introduction: This study sought to explore and describe the interpretation which adolescents ascribe to the term wellness at a selected high school in the Western Cape Province of South Africa. Methods: A qualitative research design was utilized. Nine focus-group discussions were conducted among 58 adolescents. Sample was selected purposefully and collected data was analyzed using open coding. Results: Findings reflected adolescents' interpretations of the term wellness in the realm of holistic well-being transcending the nonexistence of illness or sickness in the body. The interpretations given include: healthy living which embrace eating enough nutritious foods, exercising regularly and being actively involved in physical activities; practicing self-care habits such as personal hygiene and grooming; well-being of the mind (psychological, emotional); having a balanced personality and interpersonal processes; being focused and goal directed and spiritual well-being. Conclusion: It is imperative to consider adolescents' understandings of wellness when planning, designing, implementing and evaluating adolescent wellness programs.

Adolescence is a unique period of physical and cognitive development that includes concurrent pubertal changes and sex-based vulnerabilities. While diffusion tensor imaging (DTI) studies show white matter maturation throughout the lifespan, the state of white matter integrity specific to adolescence is not well understood as are the contributions of puberty and sex. We performed whole-brain DTI studies of 114 children, adolescents, and adults to identify age-related changes in white matter integrity that characterize adolescence. A distinct set of regions across the brain were found to have decreasing radial diffusivity across age groups. Region of interest analyses revealed that maturation was attained by adolescence in broadly distributed association and projection fibers, including those supporting cortical and brain stem integration that may underlie known enhancements in reaction time during this period. Maturation after adolescence included association and projection tracts, including prefrontal-striatal connections, known to support top-down executive control of behavior and interhemispheric connectivity. Maturation proceeded in parallel with pubertal changes to the postpubertal stage, suggesting hormonal influences on white matter development. Females showed earlier maturation of white matter integrity compared with males. Together, these findings suggest that white matter connectivity supporting executive control of behavior is still immature in adolescence.
Full Text Available Objective: The aim of this study is to review the sociodemographic characteristics, maternal, natal and postnatal outcomes of adolescent pregnancy. Subjects and method: The records of all adolescent pregnancies (aged 13–19 years delivered at Sisli Hamidiye Etfal Research and Training Hospital, Istanbul, Turkey, over a period of two years were reviewed. Structured survey was conducted with adolescent mothers over the phone. Results: The incidence of adolescent pregnancy was 7.06%; 91.1% of the cases were reported to be married. Consanguineous marriage was found to be 27.6%. Maternal anaemia was detected in 43.1% of cases. Premature birth rate was 6.3%. The rate of Cesarean section was 31.8%. Adolescent mothers were categorized into two groups: 17 years and below and above 17 years. The maternal, natal and postnatal outcomes were not statistically different between the two groups. Conclusions: Health policies should be revised and improved to take the necessary steps for providing adequate health services for adolescents and for improving prenatal, natal and postnatal care of pregnant adolescents.

This pilot study explored the associations between parent and adolescent reports of adolescent attachment and glycemic control in adolescents with Type 1 diabetes. We hypothesized that more secure attachment would correlate with more optimal diabetes control. Thirty-one families completed written self-report questionnaires about adolescent attachment, demographic data, and diabetes control. Adolescents and parents reported on their perceptions of adolescents' attachment to mothers and fathers. Mean HbA1c for the sample was 7.6% (SD = 1.14). Mothers' perceptions of adolescents' attachment were significantly correlated with adolescents' hemoglobin A1c (r = -.42, p = .022), indicating that maternal perceptions of more secure attachment was associated with better glycemic control. Neither fathers' perceptions nor adolescents' reports of attachment was significantly correlated with glycemic control. Attachment appears to be associated with glycemic control in this population though the mechanisms are unclear. Mothers' perceptions of attachment had the strongest associations with control, not adolescent reports. Further research is needed to understand the mechanisms through which parent reports of adolescent attachment are associated with glycemic control.

Ostracism can lead to strong behavioral responses, including diminished prosocial behavior. To date, experimental research examining this effect has only been conducted with adults. The current study consisted of 40 adolescents, half of whom were experimentally ostracized using the Cyberball paradigm. Participants' subsequent levels of pronounced prosocial behavior were measured, and personality traits were examined as possible moderators in participant behavioral responses. Results revealed that, compared to controls, ostracized adolescents showed less prosocial behavior, and this was moderated by having an "open" personality.

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

In expressed emotion (EE) theory, it is held that high EE household environments enhance adolescent psychopathological distress. However, no longitudinal study has been conducted to examine if either the mother's EE or the adolescent's perception of EE predicts adolescent internalizing and externalizing symptom dimensions (an EE effect model) or vice versa (psychopathological effect model) together in one model. To unravel the reciprocal influences of maternal and adolescent perceived EE to adolescent internalizing and externalizing symptom dimensions, we tested two (i.e., one for internalizing and one for externalizing) cross-lagged panel models. In this study, it was found that both internalizing and externalizing symptom dimensions predicted the adolescent's perception of maternal EE as well as the mother's own rated EE criticism over time. The findings of this study should give both researchers and therapists a reason to reevaluate only using the EE effects model assumption in future EE studies.
Full Text Available Abstract Background An inverse social gradient in overweight among adolescents has been shown in developed countries, but few studies have examined whether weight gain and the development of overweight differs among adolescents from different socioeconomic groups in a longitudinal study. The objective was to identify the possible association between parental socioeconomic position, weight change and the risk of developing overweight among adolescents between the ages 15 to 21. Methods Prospective cohort study conducted in Denmark with baseline examination in 1996 and follow-up questionnaire in 2003 with a mean follow-up time of 6.4 years. A sample of 1,656 adolescents participated in both baseline (mean age 14.8 and follow-up (mean age 21.3. Of these, 1,402 had a body mass index (BMI = weight/height2kg/m2 corresponding to a value below 25 at baseline when adjusted for age and gender according to guidelines from International Obesity Taskforce, and were at risk of developing overweight during the study period. The exposure was parental occupational status. The main outcome measures were change in BMI and development of overweight (from BMI = 25. Results Average BMI increased from 21.3 to 22.7 for girls and from 20.6 to 23.6 in boys during follow-up. An inverse social gradient in overweight was seen for girls at baseline and follow-up and for boys at follow-up. In the full population there was a tendency to an inverse social gradient in the overall increase in BMI for girls, but not for boys. A total of 13.4% developed overweight during the follow-up period. Girls of lower parental socioeconomic position had a higher risk of developing overweight (OR's between 4.72; CI 1.31 to 17.04 and 2.03; CI 1.10-3.74 when compared to girls of high parental socioeconomic position. A tendency for an inverse social gradient in the development of overweight for boys was seen, but it did not meet the significance criteria Conclusions The levels of overweight and
Full Text Available Abstract Background Adequate levels of physical activity are part of a healthy lifestyle and in this way linked to better health outcomes. For children and adolescents, the physical activity guideline recommends at least 60 minutes of moderate-to-vigorous physical activity every day. However, many adolescents are not physically active enough and they spend a lot of their time on sedentary activities (such as video games. A new generation of video games that require body movements to play them, so-called "active games", could serve to increase physical activity in adolescents. The activity level while playing these games is comparable to light-to-moderate intensity physical activity. The current study aims to increase our understanding of 1 the demographic characteristics of adolescents who play active games regularly (≥ 1 hour per week and non-regularly ( Methods A cross-sectional survey was conducted in a Dutch internet panel, questioning adolescents in conjunction with one of their parents. A random sample of 320 households (with stratification on gender of the parent and the adolescent, the age of the adolescent and the region of the household was selected that owned a console or application for active video games and that had a child aged 12 through 16 years. 201 child–parent couples (63% response completed an internet survey with questions about demographics, physical activity and sedentary behaviour, and gaming behaviour. The questionnaire also contained questions designed to assess whether and how active gaming replaces other activities. Besides descriptive analyses, independent t-test, Pearson’s chi-square and Mann–Whitney test (when data were not normally distributed were used for comparisons between regular and non-regular active gamers. Results Eleven percent of the adolescents with an active game in their household never used the game. There were no significant differences in gender, education level (of adolescent and

Reports on the findings of an Australian survey of adolescents concerning the extent of skipping breakfast. Finds that skippers are more likely to be dissatisfied with their body shape and to be on a diet to lose weight. Findings suggest that skipping breakfast is a matter of individual choice rather than a result of poverty. (Author/GCP)

The health effects of eating disorders (EDs) in adolescence have been widely studied, but their impact on present adolescent psychosocial adjustment and development have been overseen. This study aimed to investigate the association between EDs and career aspirations in middle adolescence. The participants were 147 adolescents diagnosed with EDs. Participants reported on their future career aspirations, and these were coded according to the International Standard Classification of Education of 1997. Of the participants, 83 adolescents were followed up longitudinally, and their aspirations were reassessed and compared for stability across the two assessments. Moreover, participants' career aspirations were compared to those of healthy (non-ED) best-friend controls. Health-related and social-behavioral science careers were chosen significantly more by adolescents with an ED as compared to their non-ED counterparts. For adolescents with an ED, career choices were consistent across reassessments. These findings suggest that adolescents with an ED gravitate toward careers associated with their pathology, namely, both facets of their mind-body pathology. This finding may indicate restricted identity development for adolescents with an ED. Suggestions for treatments protocols to include identity exploration are discussed.

Sexual life is one of the most important health-related behaviors of adolescents. WHO has proposed the Narrative Research Method, a way to identify adolescents' sexuality as seen by themselves. The aim of the study was to apply the narrative method as a new research method in order to reveal the level of adolescents' knowledge about sexual life and their attitude to it in Georgia. Two groups of adolescents have been investigated. First group (n=69, age 14-16) consisted of students of secondary school in Tkibuli, second group (n=58, age 17-19) -- of students of the Tbilisi State Medical University College. 81.8% of the total number of respondents think that the couple should have some physical intimacy "within the limits"; sexual relationships before marriage were acceptable to 49.6%; in case of unexpected pregnancy or STD almost 50% would have addressed parents; in case of pregnancy 28% would have consider abortion and 55% -- marriage. The study was a pilot one. It has shown the advisability of the narrative research method as an effective approach to the investigation of adolescents sexuality especially in countries where the direct questions are not acceptable because of different reasons.
Full Text Available The objective of this study was to determine time trends (1982–2006 in total fat intake and changes in fatty acid structure intake in adolescents from Warsaw in view of increasing prevalence of obesity. Data come from four successive surveys randomly selected samples of adolescents (aged 11–15 years old, from Warsaw region. In total 9747 pupils have been examined, with response rate varying from 55% to 87% depending on year. Surveys were done always in the spring season of the year. Food intake was assessed by using 24 hours recall method of consumption by the pupils all products, including enriched, dishes and beverages as well as diet supplements, in the last 24 hours preceding the examination. The content of energy and nutrients was calculated by means of own computer softwares (DIET 2 and 4, taking into account successive revisions of the tables of food composition and nutritional values, as well as current Polish DRI. A significant decreasing trend was found in intake of total fat, of saturated fatty acids (SFA and cholesterol. The percentage of energy from total fat, also decreased both in boys (to 35,1% and girls (to 33,7%, what failed to reach the desired level below 30% of energy from fat which is recommended. Also significant decrease of SFA consumption was not satisfactory enough to approach the values <10% of energy recommended as was from 13% to 15%. Decreasing trends in fat intake was not in accordance with the trend in obesity prevalence in the adolescents as average BMI is going up. To stabilize the health-oriented changes especially in the diets of adolescents, further activity is desired from professionals working with prevention of adolescents obesity.

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

Adolescent risk-taking behavior has been associated with age-related changes in striatal activation to incentives. Previous cross-sectional studies have shown both increased and decreased striatal activation to incentives for adolescents compared to adults. The monetary incentive delay (MID) task, designed to assess functional brain activation in anticipation of reward, has been used extensively to examine striatal activation in both adult and adolescent populations. The current study used this task with a longitudinal approach across mid-adolescence and late adolescence/early adulthood. Twenty-two participants (13 male) were studied using the MID task at two time-points, once in mid-adolescence (mean age=16.11; SD=1.44) and a second time in late adolescence/early adulthood (mean age=20.14; SD=.67). Results revealed greater striatal activation with increased age in high- compared to low-incentive contexts (incentive magnitude), for gain as well as for loss trials (incentive valence). Results extend cross-sectional findings and show reduced striatal engagement in adolescence compared to adulthood during preparation for action in an incentive context.

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

Although cross-sectional twin studies have assessed the genetic and environmental etiologies of substance use during adolescence and early adulthood, comparisons of results across different samples, measures, and cohorts are problematic. While several longitudinal twin studies have investigated these issues, few corroborating adoption studies have been conducted. The current study is the first to estimate the magnitude of genetic, shared environmental, and non-shared environmental influences on substance use (cigarettes, alcohol, and marijuana) from ages 14 to 18 years, using a prospective longitudinal adoption design. Adoptive and control sibling correlations provided substantial evidence for early genetic effects on cigarette, alcohol, and marijuana use/no use. Shared environmental effects were relatively modest, except for alcohol use, which showed increases in late adolescence (age 17 to 18 years). Sibling similarity for quantity/frequency of use also support additive genetic influences across adolescence, with some shared environmental influences for all three substances. To test the stability of these influences across time, a series of independent pathway models were run to explore common and age-specific influences. For all substances, there were minimal age-specific additive genetic and shared environmental influences on quantity/frequency of use. Further, there was a trend toward increasing genetic influences on cigarette and alcohol use across ages. Genetic influences on marijuana were important early, but did not contribute substantially at age 17 and 18 years. Overall, the findings indicate that genetic influences make important contributions to the frequency/quantity of substance use in adolescence, and suggest that new genetic influences may emerge in late adolescence for cigarette and alcohol use.

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

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

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

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

In this study, we examined factors that influenced doula use among adolescent mothers in a community-based childbirth education and doula program. We used a qualitative case study approach to gather perspectives from adolescent mothers and doulas through semistructured interviews, field observations, and a focus group. These women collectively revealed multiple themes related to doula use among adolescent mothers, including relationship development and barriers to doula use at the individual and structural levels. Effective training and support for doulas that serve adolescent clients can improve these mothers' birth experiences, and program planners in the United States and other countries can use process evaluations to improve doula programs for adolescent mothers.
Problematic use of the Internet by children and adolescents is a newly emerging disorder that has alerted health authorities throughout the world. In Iran, despite the very high speed rate of Internet spread, there is not enough data on the rate of Internet addiction among the adolescents. This study is the first nationwide study that addresses this issue. Overall 4500 students of high school or pre-college schools were recruited from 13/31 provinces of Iran by a cluster sampling method and 4342 (96%) participated. Two self-rated questionnaires (one demographics and one Young's Internet addiction scale) were filled b the participants. Data were analyzed by SPSS software. 962 (22.2%) of the study participants were labeled as having "internet addiction." Males were significantly more likely to be an internet addict (PInternet addiction (Pinternet addiction, and the least rate of addiction was observed when the mother was a housewife (PInternet addiction (PInternet addiction. This study showed that Internet addiction in Iranian adolescents is prevalent, and has several independent factors, from which, family relations is most likely to be modifiable. Improvements in family relations and more strict parental supervision, especially when mothers have active job employment, are recommended.

Internet Addiction (IA) is associated with adverse psychosocial development and mental disorders. The study aims were to evaluate the psychosocial profiles and psychiatric comorbidities associated with IA among adolescents. A case-control study was conducted among 129 adolescents in the outpatient setting of the Adolescent Health Unit of the Second University Department of Pediatrics in Athens, Greece. The case group consisted of 86 adolescents with IA as evaluated following psychiatric interview with two independent examiners. The control group consisted of 43 adolescents without IA, frequency matched for age and gender with case group participants. The study findings indicated that adolescents with IA were significantly more likely to have divorced parents (p = 0.012) and/or dysfunctional familial relationships (p depression (10.5 vs. 0%; p = 0.022). Adolescent IA is associated with deterred familial functions, poor academic performance, engagement in high-risk behaviors, and an augmented likelihood for depression.
Full Text Available Children and adolescents with behavioral disorders are often referred to residential homes. These homes cater and treat socially disadvantaged adolescents with a history of deviant behavior. This study investigated the environment of eight adolescents in these residential homes and four non-aggressive adolescents living with their families. The daily activities were recorded by using camera-glasses attached to the subject. These activities took place in school, leisure time, family and residential homes. Other additional methods were used to investigate the perception and experience of these adolescents. The results of this study indicate that the adolescents in residential homes have a smaller living space in contrast to the non-aggressive adolescents. They also have less close relationships and fewer interactions with their peers. Moreover they have more conflicts and show more often aggressive behavior and they are more often victims of aggression.
The study examined age and gender differences in leadership aspirations among teenage adolescents. It was hypothesized that adolescents' valence, self-efficacy and attribution perceptions about leadership would be predictive of their aspirations to leadership. Altogether 52 fourth form and 78 seventh form high school students completed a questionnaire measuring (a) overall leadership aspirations, (b) 13 valence-instrumentality expectancies for 13 leadership outcomes, (c) self-efficacy perceptions, and (d) attributions of effective leadership. The results revealed significant gender differences in valence scores and significant age differences in self-efficacy and attribution measures. Regression analyses indicated that fourth formers' leadership aspirations were significantly predicted from their "ease-of-success" self-efficacy expectation; whereas seventh formers from either valence perceptions (males) or self-efficacy and attribution scores (females). These results were discussed in the context of the valence and self-efficacy models of career decision-making processes and attribution theory.

This research investigated youth leadership experiences of adolescent girls who participated in a comprehensive feminist-based leadership program. This qualitative study utilized a grounded theory approach to understand changes that occurred in 10 female adolescent participants. The words of the participants revealed that initially they viewed leadership in traditional terms and were hesitant to identify themselves as leaders or to see themselves included within their concepts of leadership. Following the program their view of leadership expanded and diversified in a manner that allowed for inclusion of themselves within it. They spoke with greater strength and confidence and felt better positioned and inspired to act as leaders. Participants identified having examples of women leaders, adopting multiple concepts of leadership, and participating in an environment of mutual respect and trust as factors that contributed to their expanded conceptualization.
Full Text Available Adolescents' behavior is often a matter of concern, given their increased likelihood of enacting antisocial behaviors, which cause disruptions in the social order and are potentially harmful for the adolescents themselves and for the people around them. In this six-wave longitudinal study we sought to examine the interplay among maternal empathy, multiple indicators of mother-adolescent relationship quality (i.e., balanced relatedness, conflict, and support, and adolescent antisocial behaviors rated both by adolescents and their mothers. Participants for the current study were 497 Dutch adolescents (56.9% males followed from age 13 to 18, and their mothers. A series of cross-lagged panel models revealed reciprocal associations between maternal empathy and mother-adolescent relationship quality and between mother-adolescent relationship quality and adolescent antisocial behaviors. Interestingly, we also found some indirect effects of adolescent antisocial behaviors on maternal empathy mediated by mother-adolescent relationship quality. Overall, this study further highlights a process of reciprocal influences within mother-adolescent dyads.

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

The study aimed to explore how adolescents communicate food images in a widely used social media image-sharing application. We examined how and in what context food was presented and the type of food items that were frequently portrayed by following a youth related hashtag on Instagram. The hashtag #14år ("14 years") was used to find adolescent users on Instagram: these users public photo streams were then searched for food items they had shared with others. Food items were identified and categorized based on type of food and how the food items were presented. Most of the adolescent users (85%) shared images containing food items. A majority of the images (67.7%) depicted foods high in calories but low in nutrients. Almost half of these images were arranged as a still life with food brand names clearly exposed. Many of these images were influenced by major food marketing campaigns. Fruits and vegetables occurred in 21.8% of all images. This food group was frequently portrayed zoomed in with focus solely on the food, with a hashtag or caption expressing palatability. These images were often presented in the style of a cook book. Food was thus presented in varied ways. Adolescents themselves produced images copying food advertisements. This has clear health promotion implications since it becomes more challenging to monitor and tackle young people's exposure to marketing of unhealthy foods in these popular online networks because images are part of a lifestyle that the young people want to promote. Shared images contain personal recommendations, which mean that they may have a more powerful effect than commercial advertising.

Full Text Available Objective: To evaluate the inappropriate eating behaviors (IEB of female adolescents over a one-year period. Methods: 290 adolescents aged between 11 and 14 years old participated in the three research stages (T1: first four months, T2: second four months and T3: third four months. The Eating Attitudes Test (EAT-26 was applied to assess the IEB. Weight and height were measured to calculate body mass index (BMI in the three study periods. Analysis of variance for repeated measures was used to analyze the data, adjusted for the scores of the Body Shape Questionnaire and the Brazil Economic Classification Criteria. Results: Girls at T1 showed a higher frequency of IEB compared to T2 (p=0.001 and T3 (p=0.001. The findings also indicated higher values for BMI in T3 in relation to T1 (p=0.04. The other comparisons did not show statistically significant differences. Conclusions: IEB scores of female adolescents declined over one year.

Full Text Available Abstract Background Little is known about how adolescents and their parents interact and talk about some of the key lifestyle behaviors that are associated with overweight and obesity, such as screen time (ST and sugary drink (SD consumption. This qualitative study aimed to explore adolescents' and parents' perceptions, attitudes, and interactions in regards to these topics. Methods Using an exploratory approach, semi-structured focus groups were conducted separately with adolescents and (unrelated parents. Participants were recruited from low and middle socio-economic areas in the Sydney metropolitan area and a regional area of New South Wales, Australia. Transcripts were analysed using thematic analysis for each of the four content areas (adolescent-ST, adolescent-SD consumption, parents' views on adolescents' ST and parents' views on adolescents' SD consumption. Results Nine focus groups, with a total of 63 participants, were conducted. Broad themes spanned all groups: patterns of behavior; attitudes and concerns; adolescent-parent interactions; strategies for behavior change; and awareness of ST guidelines. While parents and adolescents described similar patterns of behaviour in relation to adolescents' SD consumption and ST, there were marked differences in their attitudes to these two behaviours which were also evident in the adolescent-parent interactions in the home that they described. Parents felt able to limit adolescents' access to SDs, but felt unable to control their adolescents' screen time. Conclusion This study offers unique insights regarding topics rarely explored with parents or adolescents, yet which are part of everyday family life, are known to be linked to risk of weight gain, and are potentially amenable to change.

Photovoice is a participatory action research method in which people are given cameras and asked to take pictures of specific issues within their community. It is often used among marginalised populations. This method helps people capture specific issues within their community using photographs, critically discuss these issues within a group and present their findings to inform policies within their community. Photovoice has been used in developed countries and among adult participants; however, the extent to which it has been used in developing countries and among adolescent participants is yet to be extensively reported. In this paper, we describe the use of photovoice among male and female adolescents aged 15-19 years who participated in the qualitative phase (phase I) of the Well-being of Adolescents in Vulnerable Environments (WAVE) study in Ibadan, Nigeria. The main study was conducted among adolescents residing in disadvantaged communities within five global cities (Baltimore, USA; Ibadan, Nigeria; Johannesburg, South Africa; New Delhi, India and Shanghai, China). Our findings revealed that adolescents in Ibadan were very eager to participate, remained fully engaged throughout the process and the data obtained were rich and detailed. Some challenges encountered with using this method were that younger adolescents had a tendency to attain saturation when taking pictures much earlier than older adolescents; however, they equally discussed the pictures taken enthusiastically. Overall, our findings affirm that photovoice as a data collection method can be successfully used in research among adolescents in developing countries like Nigeria.

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

Adolescent idiopathic scoliosis(AIS)is a polygenic disease. Genome-wide association studies(GWASs)have been performed for a lot of polygenic diseases. For AIS, we conducted GWAS and identified the first AIS locus near LBX1. After the discovery, we have extended our study by increasing the numbers of subjects and SNPs. In total, our Japanese GWAS has identified four susceptibility genes. GWASs for AIS have also been performed in the USA and China, which identified one and three susceptibility genes, respectively. Here we review GWASs in Japan and abroad and functional analysis to clarify the pathomechanism of AIS.

This study examined adolescent girls' views of cosmetic surgery. Seven focus groups were run with girls aged 15-18 years (N = 27). Participants read case studies of women having cosmetic surgery, followed by discussion and exploration of their views. Thematic analysis identified four themes: (1) dissatisfaction with appearance, (2) acceptability of cosmetic surgery, (3) feelings about undergoing cosmetic surgery and (4) cosmetic surgery in the media. Results suggest the acceptability of cosmetic surgery varies according to the reasons for having it and that the media play an important role by normalising surgery and under-representing the risks associated with it.

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

Full Text Available Problematic use of the Internet by children and adolescents is a newly emerging disorder that has alerted health authorities throughout the world. In Iran, despite the very high speed rate of Internet spread, there is not enough data on the rate of Internet addiction among the adolescents. This study is the first nationwide study that addresses this issue. Overall 4500 students of high school or pre-college schools were recruited from 13/31 provinces of Iran by a cluster sampling method and 4342 (96% participated. Two self-rated questionnaires (one demographics and one Young's Internet addiction scale were filled b the participants. Data were analyzed by SPSS software. 962 (22.2% of the study participants were labeled as having "internet addiction." Males were significantly more likely to be an internet addict (P<0.001. Students whose father and/or mother had a doctorate degree were most likely to have Internet addiction (P<0.001 for both. Job engagement of mothers was significantly associated with students' internet addiction, and the least rate of addiction was observed when the mother was a housewife (P<0.001; having no exercise was associated with the highest rate of Internet addiction (P<0.001. Stepwise logistic regression models showed gender (male, older age, mother's occupation, family's financial status (either very high or very low, low quality of family relationship, and students' lower levels of religious devotion were significantly associated with having Internet addiction. This study showed that Internet addiction in Iranian adolescents is prevalent, and has several independent factors, from which, family relations is most likely to be modifiable. Improvements in family relations and more strict parental supervision, especially when mothers have active job employment, are recommended.

Full Text Available Background: Adolescents’ future aspirations and expectations are important precursor of adult attainment. Objectives: To document rural adolescents’ understanding of their aspirations and the problems they face for achieving them. The relationship of adolescents with their family and how they feel about themselves have also been determined. Methods: This was a cross-sectional study conducted among school-going adolescents of Fashidewa block of Darjeeling district from July to October, 2007. A total of 420 students comprised the study population. Results - Among them, 41.4%, responded that they want to pursue a professional career in future. Poverty was found to be the commonest obstacle. The commonest problem-solving method was having discussions with friends. The study revealed that 56.4% of the adolescents communicated their problem and about 27.6% of them had conflict with their parents in last one year. Conclusion: Interventions at the community level like youth clubs for safe social interaction and literacy classes, training of peer educators to teach life-skills, forums for parents and teachers to discuss their own concerns and those of the adolescents may help to design programmes that will contribute to greater financial independence and employment opportunities for adolescents
Full Text Available Studies suggest marijuana impacts gray and white matter neural tissue development, however few prospective studies have determined the relationship between cortical thickness and cannabis use spanning adolescence to young adulthood. This study aimed to understand how heavy marijuana use influences cortical thickness trajectories across adolescence. Subjects were adolescents with heavy marijuana use and concomitant alcohol use (MJ + ALC, n = 30 and controls (CON, n = 38 with limited substance use histories. Participants underwent magnetic resonance imaging and comprehensive substance use assessment at three independent time points. Repeated measures analysis of covariance was used to look at main effects of group, time, and Group × Time interactions on cortical thickness. MJ + ALC showed thicker cortical estimates across the brain (23 regions, particularly in frontal and parietal lobes (ps < .05. More cumulative marijuana use was associated with increased thickness estimates by 3-year follow-up (ps < .05. Heavy marijuana use during adolescence and into young adulthood may be associated with altered neural tissue development and interference with neuromaturation that can have neurobehavioral consequences. Continued follow-up of adolescent marijuana users will help understand ongoing neural changes that are associated with development of problematic use into adulthood, as well as potential for neural recovery with cessation of use.

Full Text Available Eating disorders lead to special biological and psychological states. The result of the total lack of food is treated in a distinct way by anorexia. Nutritionists have thus had difficulty in coming to an agreement on the best therapy to prevent such disorders. First it is essential to understand which treatment aims are and then to attempt to know how the several treatment models used nowadays can reach those aims. Someone who suffers from eating disorders, together with an inner deformation, suffers from too much sensitiveness. In order to solve these problems, one needs a change in the relationship with oneself, with the others and with the world. This study presents a teenager’s case study – Anorexia. Is, in fact, a problem that society faces and can’t ignore. Many youngsters have already died and others are following their steps. But there are also those ones that succeeded in overcoming the problem and now are reporting their stories.

Together these studies seem to suggest that the attentional effects seen in adult observers who have colour-grapheme synaesthesia may in fact reflect...... an expertise related modulation between long-term colour-grapheme associations. To explore this hypothesis a follow-up screening of AR’s colour-grapheme associations revealed that a number of letters are still settling on their final colour association – colour changes that AR herself was unaware of, e...

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

Full Text Available Abstract Background 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. Methods 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. Results 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. Conclusions Adolescents are commonly exposed to cyberbullying, but it is rarely frequent or considered serious or disruptive. Cyberbullying

Adolescence is a critical period, because major physical and psychologic changes occur during a very short period of time. Changes in dietary habits may induce different types of nutritional disorders and are likely to track into adulthood. The aim of this review is to describe the key findings related to nutritional status in European adolescents participating in the HELENA (Healthy Lifestyle in Europe by Nutrition in Adolescence) study. We performed a cross-sectional study in 3528 (1845 females) adolescents aged 12.5–17.5 y. Birth weight was negatively associated with abdominal fat mass in adolescents and serum leptin concentrations (in female adolescents), providing additional evidence for a programming effect of birth weight on energy homeostasis control. Breakfast consumption was associated with lower body fat content and healthier cardiovascular profile. Adolescents eat half of the recommended amount of fruit and vegetables and less than two-thirds of the recommended amount of milk and milk products but consume more meat and meat products, fats, and sweets than recommended. For beverage consumption, sugar-sweetened beverages, sweetened milk, low-fat milk, and fruit juice provided the highest amount of energy. Although the intakes of saturated fatty acids (FAs) and salt were high, the intake of polyunsaturated FAs was low. Adolescents spent, on average, 9 h/d of their waking time (66–71% and 70–73% of the registered time in boys and girls, respectively) in sedentary activities. Factors associated with adolescents’ sedentary behavior included the following: 1) age; 2) media availability in the bedroom; 3) sleeping time; 4) breakfast consumption; and 5) season. Sedentary time was also associated with cardiovascular risk factors and bone mineral content. In European adolescents, deficient concentrations were identified for plasma folate (15%), vitamin D (15%), pyridoxal 5′-phosphate (5%), β-carotene (25%), and vitamin E (5%). Scientists and public

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

The purpose of this 2-year, 3-wave longitudinal study of Chinese American adolescents was to examine how family obligation behaviors and attitudes change over time; how gender, nativity, and birth order predict these trajectories; and whether family obligation relates to depressive symptoms. Findings suggest that family obligation behaviors decreased over the 2-year period but that family obligation attitudes were stable. Moreover, foreign-born adolescents reported higher levels of family obligation behavior than U.S.-born adolescents, and firstborn adolescents reported higher family obligation attitudes than laterborn adolescents. There were no gender differences in family obligation behaviors or attitudes. The findings also suggest that initial higher levels of family obligation were associated with subsequently fewer depressive symptoms. Finally, changes in family obligation behaviors related to changes in depressive symptoms over time such that increasing family obligation behaviors related to decreasing depressive symptoms. The results highlight the importance of understanding the role of family obligation to Chinese American adolescents' mental health.

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

This study explores the impact of violence exposure on the mental health of the adolescents in a rural small town. A structured questionnaire was used to survey 347 adolescents. Violence experienced and witnessed by the adolescents at school, in the neighbourhood, and at home was measured. Mental health was represented by the psychiatric symptoms, depression level, and self-esteem. The level of violence perpetrated by the adolescents was also explored. Results of the multiple regression analysis show that adolescents who have been exposed to more violence, either as a victim or as a witness, report more psychiatric symptoms, higher levels of depression, and more problems of self-esteem. Being a witness of violence also contributes significantly to the variance of violence committed by the adolescents. The implications of the findings to violence prevention are discussed in the conclusion.

The purpose of this study was to examine the relationship between child maltreatment and adolescent binge drinking. Given that many victimized children have been maltreated in multiple ways, we examine the effects of co-occurrence of multiple types of maltreatment on adolescent binge drinking. We used the National Longitudinal Study of Adolescent Health (AddHealth), which included a nationally representative sample of adolescents (n=12,748). Adolescent binge drinking was defined as five or more drinks in a row at least 2-3 times per month in the past year. Among those reporting any maltreatment, 12.4% reported binge drinking compared to 9.9% among those reporting no maltreatment. Logistic regression models found that child maltreatment is a robust risk factor for adolescent binge drinking controlling for parental alcoholism. In particular, all types of or combinations of types of maltreatment were strongly associated with adolescent binge drinking, controlling for age, gender, race, parental alcoholism and monitoring. Research examining the effect of childhood maltreatment on later alcohol abuse needs to recognize the clustering effects of multiple types of childhood maltreatment on alcohol problems.
In the representative studies published so far on the outcome of analytic child psychotherapy (Dührssen 1964; Fonagy and Target 1996) no techniques of treatment were mentioned. The following paper describes in detail the technique of treatment on which the Heidelberg Study "On the Therapeutic Outcome in Child and Adolescent Psychotherapy" is based, as it developed from 1975 to 1993 at the Heidelberg Institute for Child and Adolescent Psychotherapy. Starting from Piaget's findings that the cognitive faculties of a child up to the age of 11 completely differ from those of an adult and taking into consideration the cerebral information processing and "the intellect pervadet sensory" (Schopenhauer) it is demonstrated that children take their intrapsychic and interpersonal conflicts into analytic play therapy or into role play on analogous levels. Protected by a safe distance from being aware of their conflicts they will on the analogous levels understand, work through, partially solve their conflicts and make use of it in reality without conscious recognition. The term "analogous level" is defined and the manifold possibilities of therapeutic intervention on this level are demonstrated. The efficacy of therapeutic treatment on analogous levels is discussed.

Full Text Available Ostracism has an influence on psychological and social functioning. The aim of this study is to examine ostracism among gifted students, with regard to gender and grade levels. Also, the relationship between ostracism and intelligence level was investigated. The study was conducted in a gifted education center, with 94 gifted students who were attending middle school (grades 5-8. The Ostracism Experience Scale for Adolescents and Wechsler Intelligence Scale for Children – Revised Form were employed as data collection tools. According to the findings obtained from the study, it is concluded that ostracism did not differ in terms of gender among gifted students. Besides, being socially excluded may be higher in 8th grades than 6th and 7th grades. Also in the study, a positive correlation was found between intelligence level and ostracism. Discussion and suggestions were also provided based on the results.

The scoliometer readings in both standing and sitting position of 2071 children and adolescents (1099 boys and 972 girls) aged from 5 to 18 years old were studied. The angle of trunk rotation (ATR) was measured, in order to quantify the existing trunk asymmetry. Children and adolescents were divided in two groups according to the severity of trunk asymmetry. In the first group asymmetry was 1 to 6 degrees and in the second group was 7 or more degrees. Radiographic and leg length inequality evaluation were also performed in a number of children. The mean frequency of symmetric (ATR = 0 degrees) boys and girls was 67.06% and 65.01% for the standing screening position and 76.5% and 75.1% for the sitting position, respectively. The mean difference of frequency of asymmetry (ATR > 0 degrees) at standing minus sitting forward bending position for boys and girls was 10.22% and 9.37%, respectively. The mean frequency of asymmetry of 7 or more degrees was 3.23% for boys and 3.92% for girls at the standing forward bending position and 1.62% and 2.21% at the sitting, respectively. Girls are found to express higher frequency of asymmetry than boys. Right trunk asymmetry was more common than left. The sitting position is the preferred screening position for examining the rib or loin hump during school screening as it demonstrates the best correlation with the spinal deformity exposing the real trunk asymmetry.

This study explores the impact of family structure and parental education on adolescents' substance use using a racially diverse sample of 14,268, 12th-grade high school adolescents. Findings reveal that family structure affects adolescents' substance use. In addition, racial differences are noted. African American adolescents report a relatively lower rate of substance use compared to White and Hispanic adolescents, yet they are gravely affected by substance use outcomes. The study lends further support that family structure and parental education variables may buffer adolescents from substance abuse influences. Implications for practice and policy are discussed.

Context: Adolescent health is a relatively new focus area of India’s National health program. However, little evidence is available for the existing problems especially in adolescent slum population. A study was planned to explore the problems of adolescent pertaining to sexuality, physical health, tobacco and alcohol use in slums of Urban Meerut, and create evidence base for informed planning and decision making by the local health authorities. Aims: To study the adolescent health in the slums of Meerut City, India. Settings and Design: Entire slums of Urban Meerut, cross-sectional study. Materials and Methods: Study was done in the slums of Meerut city, in Northern India. WHO 30 cluster sampling technique was used. Thirty slums were selected from the list of all the slums of Meerut, 210 adolescents were selected with 7 adolescents from each slum. Statistical Analysis: Proportions and Chi-square test. Results: More than one third of the (36.7%) adolescents reported to have a current health problem, however only half of these sought medical help for treatment. Tweleve percent of adolescents reported history of alcohol or tobacoo use. Nine percent adolescents complained of stressful atmosphere at home. About 10% adolescents in the surveyed population gave history of sexual activity, but only one third of them had used condom during their last sexual intercourse. Conclusion: This study reflects the high morbidity and poor treatment seeking behaviour among adolescents in urban slums. A significant proportion of adolescents indulge in high risk sexual behavior, tobacco and alcohol use. There were significant gender differences with regards to treatment seeking behaviour, sexual behaviour, tobacco and alcohol use. The gender nuances must be taken into account while planning interventions for this section of population. PMID:25302222

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

Although the consequences of physical activity have been carefully documented, less is known about its correlates, particularly among children and youth. Based on a representative national survey of 1131 Icelandic adolescents, the study examined various physical, psychological, social and demographic factors related to physical activity. Male sex, significant others' involvement in physical activity (father, friend and older brother), sociability, perceived importance of sport and of health improvement and satisfaction with mandatory gym classes in school, were all related to more involvement, whereas hours of paid work and TV-viewing were related to less. Furthermore, the data suggested that the influence of friend's participation in physical activity depends on his or her emotional significance. Influential others appeared to affect males and females in the same way. The meaning of the results and their implications for future research are discussed.

A school-based cross-sectional study was carried out in seven cities in Arab countries, namely, Algeria, Jordan, Kuwait, Libya, Palestine, Syria, and United Arab Emirates. A multistage stratified random sampling technique was used. The total sample included was 4698 adolescents aged from 15 to 18 years (2240 males, 2458 females. The International Obesity Task Force (IOTF reference standard was used to classify the adolescents as nonobese, overweight, and obese. Results. Among males, overweight was highest among Kuwaiti adolescents (25.6%, followed by Jordanian (21.6%, and Syrian (19.7% adolescents. Among females, the highest prevalence of overweight was reported in Libyan adolescents (26.6%, followed by Kuwaiti (20.8%, and Syrian (19.7% adolescents. As for obesity, Kuwaiti adolescents showed the highest prevalence of obesity for both males (34.8% and females (20.6%. Conclusion. There is an urgent need to establish a plan of action to combat obesity in schoolchildren in these countries.
Full Text Available Adolescence is the period of physical and psychological development from the onset of puberty to maturity. The World Health Organization defines an adolescent as a person between ages 10 and 19 years. A dramatic shift in thinking from concrete to abstract gives adolescents a whole new set of mental tools, to analyze situations logically in terms of cause and effect, appreciate hypothetical situations, evaluate alternatives, introspection, decision making and cognitive abilities. Adolescents experience intense physical, psychological changes as they make transition from childhood to adulthood. This period of transition is the most vulnerable time. Adolescents are at risk of developing behavioral problems like school failure and drop outs, substance abuse, delinquency and violence, sexually transmitted diseases, unwanted pregnancies, domestic violence, stress and depression and risk-taking behaviour. It is the responsibility of the society to utilize this period constructively through education, counseling, mass media, awareness programmes and address the reproductive health needs of adolescents. The present study analyzes the psychosocial risk status and knowledge of reproductive health in adolescents in Raipur city. The study recommends implementation of provisions by government to provide continuous education and economic security for adolescents. Programmes like age-appropriate reproductive health curriculum should be introduced in schools and colleges with counseling facilities at school and primary health care levels.
Full Text Available Abstract Background Within the Self-Determination Theory (SDT framework, the first major study aim was to investigate the SDT tenets in an obese adolescent population by examining the factor structure of the Behavioural Regulation in Exercise Questionnaire-2 (BREQ-2 and by investigating associations between physical activity (PA and motivation in obese adolescents. The second aim was to study differences in motivation according to adolescents' educational level, since lower educated obese adolescent are a sub-risk group for lower PA levels among the obese adolescents. The third aim was to investigate whether attending a residential obesity treatment program could lead to an increase in autonomous motivation towards PA and to see if the treatment effect on motivation was different in low versus high educated youth. Methods For the first study aim, the sample comprised 177 obese adolescents at the start of a 10-month multidisciplinary residential obesity treatment program (BMI = 35.9 ± 6.0 kg/m2, 15.1 ± 1.5 years, 62% girls. A subsample of 65 adolescents (stratified by educational level were divided into low (n = 34 versus high educated (n = 31 as part of the second and third study aim. Motivation was assessed using the BREQ-2 and PA using the Flemish Physical Activity Questionnaire. Results Exploratory factor analysis showed sufficient validations with the original factor for 17 out of 19 BREQ-2 items. Significant positive correlations were found between PA and the composite score of relative autonomy (r = 0.31, p Conclusions The BREQ-2 can be used in an obese adolescent population. Higher levels of autonomous motivation towards PA were related to higher PA levels. Adolescents had increases in both autonomous and controlled forms of motivation during treatment. Special attention for lower educated adolescents during treatment is needed, as they have a lower autonomous motivation at the start of treatment and an increase in introjected

Full Text Available Abstract Background This study aimed to canvass the nature of adolescent-parent interactions about weight, particularly overweight, and to explore ideas of how to foster supportive discussions regarding weight, both in the home and with family doctors. Methods A market research company was contracted to recruit and conduct a series of separate focus groups with adolescents and unrelated parents of adolescents from low-middle socio-economic areas in Sydney and a regional centre, Australia. Group discussions were audio recorded, transcribed, and then a qualitative content analysis of the data was performed. Results Nine focus groups were conducted; two were held with girls (n = 13, three with boys (n = 18, and four with parents (20 mothers, 12 fathers. Adolescent and parent descriptions of weight-related interactions could be classified into three distinct approaches: indirect/cautious (i.e. focus on eating or physical activity behaviors without discussing weight specifically; direct/open (i.e. body weight was discussed; and never/rarely discussing the subject. Indirect approaches were described most frequently by both adolescents and parents and were generally preferred over direct approaches. Parents and adolescents were circumspect but generally supportive of the potential role for family doctors to monitor and discuss adolescent weight status. Conclusions These findings have implications for developing acceptable messages for adolescent and family overweight prevention and treatment interventions.

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.

Although adolescents begin to seek autonomy and strive to be out of the home on their own, the housing context remains the primary setting of their daily lives. Using survey and ethnographic data from (e.g., Winston et al., 1999), this study explored quantitatively and qualitatively how two salient aspects of the housing context, physical housing problems and household size, were associated with low-income adolescents' emotional and academic functioning, and how these associations were modified by mother-adolescent relationships (specifically, trust and communication) and gender. Results of cross-lagged hierarchical linear models suggest that adolescents living in homes with more housing problems had more mental health symptoms, whereas living in larger households was associated with higher achievement, but only in the context of lower quality mother-adolescent relationships. Qualitative analyses helped to interpret these results by illuminating potential pathways underlying associations observed in quantitative results. (PsycINFO Database Record

Full Text Available Abstract Background Spinal pain is an important health issue for adolescents resulting in functional limitations for many and increasing the risk of spinal pain in adulthood. Whilst human and animal studies suggest nutrition could influence spinal pain, this has not been investigated in adolescents. The objective of this exploratory cross sectional study was to evaluate associations between diet and adolescent spinal pain. Methods This study surveyed the spinal pain (neck and back and nutrition (specific nutrients, broad food groups, diet quality and dietary pattern of 1424 male and female adolescents at 14 years of age, in Western Australia. Results Back or neck pain were experienced by around half of the adolescents, with females more likely to experience spinal pain. Nutrition differed between sexes and deviated from optimal intakes. Vitamin B12, eggs, cereals and meat consumption were related to spinal pain in sex specific multivariate analyses including primary carer education level and adolescent waist girth and smoking. Conclusions The findings of this study suggest that certain aspects of diet may have an association with spinal pain in adolescence.

Full Text Available Abstract Background Although several studies have reported findings concerning the association between smoking and emotional/behavioural problems, little research has investigated this association after controlling for confounding factors which have been found to be significantly correlated with both cigarette smoking and emotional/behavioural problems and may have a strong effect on the relationship between adolescents' mental health and smoking. The present study attempted to assess the association between adolescents' smoking status and their emotional/behavioural problems after controlling for a number of possible confounders (i.e. age, gender, parental smoking status, exposure to family smoking, family socioeconomic status, adolescents' leisure time in a Greek nation-wide school-based sample. Methods Participants completed a questionnaire which retrieved information about age, gender, family socioeconomic status, smoking status, parental smoking, adolescents' leisure time and emotional/behavioural problems. Data were modelled using multiple logistic regression analysis with adolescents' smoking status as the dependent variable. Results A total of 1194 (i.e. 63% response rate of self-reported questionnaires (40.1% boys, 59.9% girls; 12-18 years old were returned. Data from 1030 participants with full data were analyzed. Cigarette smoking was strongly associated with higher levels of emotional/behavioural problems (p Conclusions This study supports the association between smoking and emotional/behavioural problems among adolescents. Addressing adolescents' needs regarding their emotional/behavioural health could be helpful in the development of effective anti-smoking strategies in school environment and elsewhere.

Full Text Available The purpose of this study was to identify the knowledge and use of contraceptive methods by female adolescent students. The study was cross-sectional and quantitative, using a semi-structured questionnaire that was administered to 12- to 19-year-old female students in Maceió, Brazil. A representative and randomized sample was calculated, taking into account the number of hospital admissions for curettage. This study was approved by the Human Research Ethics Committee, and Epi InfoTM software was used for data and result evaluation using the mean and chi-square statistical test. Our results show that the majority of students know of some contraceptive methods (95.5%, with the barrier/hormonal methods being the most mentioned (72.4%. Abortion and aborting drugs were inaccurately described as contraceptives, and 37.9% of the sexually active girls did not make use of any method. The barrier methods were the most used (35.85%. A significant association was found in the total sample (2,592 between pregnancy and the use of any contraceptive method. This association was not found, however, in the group having an active sexual life (559. The study points to a knowledge of contraceptive methods, especially by teenagers who have already been pregnant, but contraceptives were not adequately used. The low use of chemical methods of contraception brings the risk of pregnancy. Since abortion and aborting drugs were incorrectly cited as contraceptive methods, this implies a nonpreventive attitude towards pregnancy.

The Victorian Adolescent Health Cohort Study (VAHCS) is a long-term Australian cohort study that has documented cannabis use in young Australians from the mid-teens to the mid-30s. The study findings have described the natural history of early cannabis use, remission, and escalation and the social and mental health consequences of different patterns of use. The adverse consequences of cannabis use are most clear-cut in heavy early adolescent users. These consequences include educational failure, persisting mental health problems, and progression to other substance use. For later onset and occasional users, the risks are lower and appear to entail modest elevations in risk for other drug use compared with never users. With growing evidence of health consequences, there is a strong case for actions around early heavy adolescent users. Prevention of early use, identification and treatment of early heavy users, and harm reduction through diversion of early heavy users away from the custodial justice system into health care are all priority responses.
Full Text Available Context: Psychosocial health problems are highly prevalent and one of the hidden public health problems amongst the children and adolescents. Early diagnosis by primary care physicians and prompt referral to the specialist is very important for controlling it. Objectives: To screen all school going children for the risk of psychosocial problems, identify risk factors and refer at risk children to the psychiatrist for counseling. Material and Methods: A Cross sectional study in urban and rural field practice area of a teaching hospital in Pune. A screening tool-the youth report of pediatric symptom checklist (Y-PSC was used .Statistical analysis by Chi square test and Multivariate logistic regression was used as the test for significance. Results: Out of the total 2154 children, 328 (15.2% were found to be at risk of psychosocial problems. Statistically significant difference was observed as per type of management, medium of education, location of the school, age group, class of the student, total members in the family and socioeconomic status. No significant difference was observed as per gender or the type of the family. However after the application of multinomial logistic regression, significant statistical difference was observed only for the type of management running the schools with significantly more number of proportions of psychological disorders seen in students studying in government run schools. Conclusions: Our study clearly brings out the role of management in psychosocial impairment. The psychosocial impairment is about 15.2% with more impairment seen amongst government schools.
Full Text Available Growing consciousness about ideal body image leads to dietary modifications and consequent eating disorders among girls in developing countries like India. The present study aims to (i assess the prevalence of body weight consciousness and related behaviours among a group of adolescent girls; (ii assess the sociodemographic correlates of weight related behaviours; and (iii compare weight related behaviours of the girls of two religious groups residing in Howrah. The study is the outcome of a cross-sectional school based survey involving 280 (159 Hindu and 121 Muslim girls from standards 8 to 11. Significant differences exist between two religious groups with respect to their family size, socioeconomic profile, and media exposures (in terms of watching television. Consciousness about body weight among girls shows significant difference with respect to religion, family size (χ2=64.77, father’s occupation (χ2=60.28, level of education of both the parents, and media exposure (P<0.05. Consciousness about body weight drives them to adopt several behavioural measures like calorie restriction, food avoidance, and dieting. Sociodemographic correlates of all these behaviours have been analyzed. The study documents that concern over body image and weight loss is quite important among these urban girls.

Chronic pain in childhood and adolescence has been shown to heighten the risk for depressive and anxiety disorders in specific samples in adulthood; however, little is known about the association between a wider variety of chronic pains and internalizing mental health disorders. Using nationally representative data, the objectives of this study were to establish prevalence rates of internalizing mental health disorders (anxiety and depressive disorders) among cohorts with or without adolescent chronic pain, and to examine whether chronic pain in adolescence is associated with lifetime history of internalizing mental health disorders reported in adulthood. Data from the National Longitudinal Study of Adolescent to Adult Health (Add Health) was used (N = 14,790). Individuals who had chronic pain in adolescence subsequently reported higher rates of lifetime anxiety disorders (21.1% vs 12.4%) and depressive disorders (24.5% vs 14.1%) in adulthood as compared with individuals without a history of adolescent chronic pain. Multivariate logistic regression confirmed that chronic pain in adolescence was associated with an increased likelihood of lifetime history of anxiety disorders (odds ratio: 1.33; 95% confidence interval: 1.09-1.63, P = 0.005) and depressive disorders (odds ratio: 1.38; confidence interval: 1.16-1.64, P < 0.001) reported in adulthood. Future research is needed to examine neurobiological and psychological mechanisms underlying these comorbidities.

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 OBJECTIVE: This qualitative study explored the views and experiences of adolescents with perinatally acquired HIV in Kigali, Rwanda, regarding sex, love, marriage, children and hope for the future. DESIGN: The study enrolled 42 adolescents who had received combination antiretroviral therapy for at least 12 months, and a selection of their primary caregivers. Study methods included 3 multiple day workshops consisting of role-playing and focus group discussions (FGDs with adolescents, 8 in-depth interviews with adolescents, and one FGD with caregivers. RESULTS: The adolescents reported experiencing similar sexual needs and dilemmas as most other adolescents, but with an added layer of complexity due to fears related to HIV transmission and/or rejection by partners. They desired more advice from their parents/caregivers on these topics. Although they struggled with aspects of sex, love, marriage and having children, most agreed that they would find love, be married and have children in the future. The two most discussed HIV-related anxieties were how and when to disclose to a (potential sex/marriage partner and whether to have children. However, most adolescents felt that they had a right to love and be loved, and were aware of prevention-of-mother-to-child-transmission (PMTCT options in Rwanda. Adolescents generally spoke about their future role in society in a positive manner. CONCLUSION: Strengthening the life skills of HIV-positive adolescents, especially around HIV disclosure and reduction of HIV transmission, as well as the support skills of parents/caregivers, may not only reduce onward HIV transmission but also improve quality of life by reducing anxiety.

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.

Purpose Measuring activity spaces, places adolescents spend time, provides information about relations between contextual exposures and risk behaviors. We studied whether contextual exposures in adolescents’ activity spaces differ from contextual risks present in residential contexts and examined relationships between contextual exposures in activity spaces and alcohol/marijuana use. Methods Adolescents (N=18) aged 16–17 carried GPS-enabled smartphones for one week, with locations tracked. Activity spaces were created by connecting GPS points sequentially and adding buffers. Contextual exposure data (e.g., alcohol outlets) were connected to routes. Adolescents completed texts regarding behaviors. Results Adolescent activity spaces intersected 24.3 census tracts and contained 9 times more alcohol outlets than residential census tracts. Outlet exposure in activity spaces was related to drinking. Low SES exposure was related to marijuana use. Conclusions Findings suggest substantial differences between activity spaces and residential contexts, and suggest that activity spaces are relevant for adolescent risk behaviors. PMID:26206448

Creativity is a multifaceted construct that recruits different cognitive processes. Here, we summarize studies that show that creativity develops considerably during adolescence with different developmental trajectories for insight, verbal divergent thinking, and visuospatial divergent thinking. Next, these developmental time courses are mapped to changes in brain activity when individuals perform divergent thinking tasks. The findings point to an important role of the prefrontal cortex for generating novelty and complexity. Finally, the potentials and limitations of training creativity in adolescence are described. The findings are interpreted vis-à-vis the dynamic changes that occur during adolescence in brain development and behavioral control processes.
Full Text Available Abstract Background Few studies, particularly in developing countries, have explored the relationship between adolescents and parental values with adolescent problem behaviors. The objectives of the study are to (1 describe adolescents' personal values, their problem behaviors, and the relationships thereof according to gender and (2 examine the relationship between parental values, adolescent values, and adolescents' problem behaviors among sixth-grade students and one of their parents. Methods The data used in these analyses were from the baseline assessment of a school-based HIV risk reduction intervention being conducted and evaluated among sixth grade students and one of their parents across 9 elementary schools in The Bahamas. Personal values were measured by the Portrait Values Questionnaire (PVQ. Seven reported problem behaviors were queried from the students, which included physical fight with a friend, drank alcohol, beer, or wine, smoked a cigarette, pushed or carried any drugs, carried a gun, knife, screwdriver or cutlass to use as a weapon, had sex and used marijuana or other illicit drugs over the past 6 months. Multilevel modeling for binary data was performed to estimate the associations between adolescent and parental values and adolescent problem behaviors. Results Among 785 students, 47% of the students reported at least one problem behavior. More boys (54% reported having one or more problem behaviors than girls (41%, p Conclusion In designing interventions for reducing adolescents' problem behaviors, it may be important to understand the values associated with specific problem behaviors. Further exploration regarding lack of association between adolescent and parental values and problem behaviors is needed.

Parents are likely to be key influences on children's physical activity behaviors, although it is not clear how. This study was designed to explore parents' roles in Iranian adolescent girls' physical activity habit development. A qualitative study was conducted by means of semistructured one-to-one interviews with 25 participants, including 16 adolescent girls (10-19 years of age), seven mothers, and two fathers. Content analysis was applied. Two main themes emerged as parental role in adolescent girls' physical activity behavior: developing interest in physical activity (making children familiar with physical activity, discovering talents, and role modeling) and providing support to adolescents for physical activity (material and immaterial). This study provided a better understanding of how Iranian parents influence their children's physical activity behavior. This will enable nurses to design more effective family-based interventions.
Full Text Available This paper is based on partially exploratory and partially descriptive research design to find out AIDS awareness and agreement of parents and teachers on educating adolescents about contraception techniques. For this study 60 parents and 60 teachers were interviewed from 10 different Govt. Senior Secondary schools in district Sangrur, Punjab, India. The random sampling technique was used. The knowledge of AIDS among parents was found partial. Mothers showed lesser knowledge of AIDS in comparison to fathers. Teachers showed comprehensive knowledge of AIDS. Majority of respondents disagree on educating adolescents about contraception techniques. But all responded reported to be in agreement to provide full knowledge about AIDS to adolescents. The education of contraception for adolescent found to be associated with the knowledge of prevention from unwanted pregnancy. Parents and teachers showed propensity to provide such education to adolescents which advocates sexual abstinence until marriage. The plausible reason to such perception could be that in most of Indian societies there is taboo on sex or sex related discussion.

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

All participants were examined by a trained dental team in a classroom using a dental mirror and a periodontal probe. Periodontal examination included plaque scores, calculus scores, probing depth measurements and bleeding on probing. These measurements were recorded for the Ramfjord index teeth. Results. A total of 397 15-year-old participants were examined in this pathfinder study. There were 240 females (60.45% and 157 males (39.55%. Of the total participants 196 (49.37% were urban adolescents while 201 (50.63% were from rural communities. Mean probing depth was 3.34 ± 0.57 mm with a range of 1 to 10 mm; a relatively high proportion (34.26% of these subjects presented with at least one site with pockets of 5 mm or deeper. Males presented with greater plaque, calculus and probing depths than females. When urban and rural populations were compared, urban participants presented with more plaque, probing depths and bleeding on probing. Greater pocket depths were found to be related to the presence of plaque calculus and bleeding on probing. Conclusions. Overall, rather high incidences of periodontal pockets ≥ 5 mm were detected in this population. This data should serve to prepare further more detailed epidemiological studies that will serve to plan and implement prevent and treat strategies for periodontal diseases in Georgia and also help make manpower decisions.

This study treated a key relationship in the developmental ecology of adolescence, friendships, as multidimensional and context specific. First, it examined 4 characteristics of friends (academic achievement, alcohol use, emotional distress, and extracurricular participation) as independent factors and as components in holistic friendship group profiles. Longitudinal analyses of 9,224 adolescents (ages 12-20) revealed that multiple characteristics of friends predicted adolescent behavioral problems, as did membership in the best adjusted group profile. Second, the study examined whether the associations between friendship factors and adolescent behavior varied as a function of the larger peer network and school context, finding that network centrality, school academic press, and intergenerational bonding in schools conditioned the role of friends' characteristics and group profiles in positive and negative ways.

This study considers the development of resemblance between 741 adolescents and their biological parents, across six NEO-PI-R personality traits known to be important in psychological problems: anger-hostility, impulsiveness, vulnerability, assertiveness, excitement-seeking, and self-discipline. We modelled the association between perceived parental warmth and rejection at age eleven and personality resemblance to parents at about age sixteen. Parenting experienced during early adolescence was related to the degree and direction in which adolescents resembled their parents five years later in life. Rejection, especially from fathers, significantly predicted a smaller resemblance to both the parents. Girls were more strongly affected by parental quality than boys, and there was some indication that adolescents responded in opposite ways to parenting from mothers and fathers. This study is a first step in uncovering the complex interplay between parenting, gender, and the current generation's ability to develop personality traits independent from the previous generation.

Full Text Available Abstract Background The objective of the study is to improve general practitioners' diagnoses of adolescent depression. Major depression is ranked fourth in the worldwide disability impact. Method/Design Validation of 1 three key questions, 2 SCL-dep6, 3 SCL-10, 4 9 other SCL questions and 5 WHO-5 in a clinical study among adolescents. The Composite International Diagnostic Interview (CIDI is to be used as the gold standard interview. The project is a GP multicenter study to be conducted in both Norway and Denmark. Inclusion criteria are age (14–16 and fluency in the Norwegian and Danish language. A number of GPs will be recruited from both countries and at least 162 adolescents will be enrolled in the study from the patient lists of the GPs in each country, giving a total of at least 323 adolescent participants. Discussion The proportion of adolescents suffering from depressive disorders also seems to be increasing worldwide. Early interventions are known to reduce this illness. The earlier depression can be identified in adolescents, the greater the advantage. Therefore, we hope to find a suitable questionnaire that could be recommended for GPs.
Full Text Available Background: Physical activity is important for adolescent health. The current study aimed to explore factors that predict physical activity among adolescents. Methods: This was a cross-sectional study of physical activity among a sample of adolescents in Tabriz, Iran. Information on physical activity was collected using a modified version of the Adolescent Physical Activity and Recall Questionnaire (APARQ. In addition, a self-administrated questionnaire was used to collect data on demographic characteristics, perceived family support, and self-efficacy. Both univariate and multivariate logistic regression analyses were performed to examine the association between physical activity and independent variables including gender and psychosocial predictors. Results: In all, 402 students were studied. The mean age of adolescents was 12.93 (SD=0.49 years; 51.5% were female. The mean time of moderate and vigorous physical activity for all adolescents was 44.64 (SD=23.24 Metabolic Equivalent (MET min per day. This figure for female adolescents was 38.77 (SD=19.94 MET min per day and for males it was 50.87 (SD=24.88 (P<0.001. The results obtained from multiple logistic regression analysis indicated that female gender (OR=2.59, 95% CI=1.46–4.57, P=0.001 and poor family support (OR=1.10, 95% CI=1.03–1.20, P=0.038 were the most significant contributing factors to low level physical activity in adolescents. Other variables studied did not show any significant results. Conclusion: The findings from the current study indicated that female adolescents were at risk of lower level of physical activity. In addition, it was found that the lack of family support represented an increased risk for low-level physical activity. It seems that family support should be an integrated part of any health education/promotion programs for improving physical activity among young adolescents in general and for female adolescents in particular.

The diagnostic features and treatment histories of 11 adolescents with multiple personality disorder (MPD) are presented. Clinical evaluation revealed that the majority of these adolescents manifested extremely variable school performance, disruptive behavior, trances, amnesias, mood swings, sharp changes in personality, apparent lying, voices heard in the head, and depression. All had a history of childhood trauma: Sexual abuse (73%), physical abuse (73%), and emotional abuse (82%). Seventy-three percent had a parent with a diagnosable dissociative disorder; 36% of the mothers had MPD. These adolescents had a mean number of 24.1 alter personalities and appear to have become multiple at a mean age of 3 years, 1 month. All patients had angry protector alters, depressed alters, scared alters, and child alters. Fifty-four percent of these cases have integrated during treatment or are progressing toward integration. The remaining cases dropped out of therapy.

Previous work on the development of intuitive knowledge about projectile motion has shown a dissociation between action knowledge expressed on an action task and conceptual knowledge expressed on a judgment task for young children. The research investigated the generality of dissociation for adolescents. On the action task, participants were asked to swing Ball A of a bifilar pendulum to some height then release it to collide with Ball B, which was projected to hit a target. On the judgment task, participants indicated orally the desired swing angle at which Ball A should be released so that Ball B would strike a target. Unlike previous findings with adults, the adolescents showed conceptual difficulties on the judgment task and well-developed action knowledge on the action task, which suggests dissociation between the two knowledge systems is also present among adolescents. The result further supports the hypothesis that the two knowledge systems follow different developmental trajectories and at different speeds.

A cross-sectional school-based survey study (N=13,284; 53% females; mean age 15.8±0.7) of 14-17-year-old adolescents was conducted in seven European countries (Greece, Spain, Poland, Germany, Romania, the Netherlands, and Iceland). The aim of the study was to investigate the prevalence of Internet addictive behavior (IAB) and related psychosocial characteristics among adolescents in the participating countries. In the study, we distinguish two problematic groups: adolescents with IAB, characterized by a loss of control over their Internet use, and adolescents "at risk for IAB," showing fewer or weaker symptoms of IAB. The two groups combined form a group of adolescents with dysfunctional Internet behavior (DIB). About 1% of adolescents exhibited IAB and an additional 12.7% were at risk for IAB; thus, in total, 13.9% displayed DIB. The prevalence of DIB was significantly higher among boys than among girls (15.2% vs. 12.7%, pInternet, and greater use of social networking sites and gaming sites. Multiple linear regression analysis showed that externalizing (i.e., behavioral) and internalizing (i.e., emotional) problems were associated with the presence of DIB.
Full Text Available Background: Zinc is important in adolescence because of its role in growth and sexual maturation. Adolescents from developing countries such as India may be at high risk of zinc deficiency because of unwholesome food habits and poor bioavailability of zinc from plant-based diets. Objectives: (1 to study zinc status and its association with profile of other micronutrients, (2 to construct a simple tool in the form of Adolescent Micronutrient Quality Index (AMQI to assess quality of diets of the girls and (3 to examine the effect of zinc supplement on health of adolescent girls. Methods: Girls (10–16 years from two secondary schools of Pune, Maharashtra state, in Western India were enrolled in a cross-sectional study (n = 630. Data were collected on dietary intake, cognitive performance, taste acuity, haemoglobin, erythrocyte zinc and plasma levels of zinc, vitamin C, β-carotene and retinol. AMQI was developed using age–sex-specific Indian dietary guidelines and healthy foods and habits described in the recent US dietary guidelines. Zinc-rich recipes were developed considering habitual diets of the girls and vegetarian sources of zinc. An intervention trial (n = 180 was conducted to assess the effect of zinc-rich dietary supplements and ayurvedic zinc (Jasad supplementation. Results: Prevalence of micronutrient deficiencies was high in these girls. Poor cognitive performance was seen in half of the girls, and salt taste perception was affected in 45%. AMQI was correlated with nutrient intakes and blood micronutrient levels (p < 0.01, indicating the potential of AMQI to measure micronutrient quality of diets of adolescent girls. Results of the intervention trial indicated that supplementation of zinc-rich recipes vis-a-vis ayurvedic Jasad zinc has the potential to improve plasma zinc status, cognitive performance and taste acuity in adolescent girls. Conclusion: Review of the studies on Indian adolescent girls demonstrates the necessity of

This study was designed to assess the benefits and barriers accruing to breast-feeding as perceived by pregnant adolescents, and to establish whether these perceptions distinguished between adolescent mothers who chose to breast versus bottle feed. Surveys were completed by 254 young women attending prenatal clinics. Overall, 19.3% indicated their intent to breast-feed. When categorized by intended method of infant feeding (breast versus bottle), breast-feeding mothers cited more benefits and fewer barriers associated with that method of infant feeding. Overall, perceived benefits were more successful than perceived barriers in distinguishing between the groups of respondents. For those interested in promoting breast-feeding among adolescent mothers, our data support an emphasis on the diverse benefits of this method of infant feeding. Our results also suggest the usefulness of peer role models in correcting misinformation and encouraging breast-feeding among adolescent mothers.

The aim of this five-wave longitudinal study was to investigate the relationship between anxiety and adolescent identity development. Participants were 1,313 adolescents who annually completed measures of anxiety and identity. Growth Mixture Modeling (GMM) analyses demonstrated that the adolescent population was best typified by two latent growth trajectory classes: a low anxiety class (n = 1,199) characterized by a low initial level of anxiety that decreased over time and a high anxiety class (n = 114) characterized by a higher initial level of anxiety that increased over time. To answer our research question, we tested a model in which the anxiety classes predicted initial levels and rates of change of three identity dimensions: commitment, in-depth exploration, and reconsideration of commitment. Findings indicated that the high anxiety adolescents displayed a more troublesome identity development than their low anxiety peers, since their commitments became weaker with age, and they reconsidered them intensively.

Full Text Available ABSTRACT CONTEXT AND OBJECTIVE: Bacterial vaginosis occurs frequently in pregnancy and increases susceptibility to sexually transmitted infections (STI. Considering that adolescents are disproportionally affected by STI, the aim of this study was to evaluate the cervicovaginal levels of interleukin (IL-1 beta, IL-6, IL-8 and bacterial sialidase in pregnant adolescents with bacterial vaginosis. DESIGN AND SETTING: Cross-sectional study at mother and child referral units in Belém, Pará, Brazil. METHODS: Vaginal samples from 168 pregnant adolescents enrolled were tested for trichomoniasis and candidiasis. Their vaginal microbiota was classified according to the Nugent criteria (1991 as normal, intermediate or bacterial vaginosis. Cervical infection due to Chlamydia trachomatisand Neisseria gonorrhoeae was also assessed. Cytokine and sialidase levels were measured, respectively, using enzyme-linked immunosorbent assays and MUAN conversion in cervicovaginal lavages. Forty-eight adolescents (28.6% were excluded because they tested positive for some of the infections investigated. The remaining 120 adolescents were grouped according to vaginal flora type: normal (n = 68 or bacterial vaginosis (n = 52. Their cytokine and sialidase levels were compared between the groups using the Mann-Whitney test (P < 0.05. RESULTS: The pregnant adolescents with bacterial vaginosis had higher levels of IL-1 beta, IL-6 and IL-8 (P < 0.05. Sialidase was solely detected in 35 adolescents (67.2% with bacterial vaginosis. CONCLUSIONS: Not only IL-1 beta and sialidase levels, but also IL-6 and IL-8 levels are higher in pregnant adolescents with bacterial vaginosis, thus indicating that this condition elicits a more pronounced inflammatory response in this population, which potentially increases vulnerability to STI acquisition.

Full Text Available Abstract Background Adolescence is characterized by marked psychosocial, behavioural and biological changes and represents a critical life transition through which adult health and well-being are established. Substantial research confirms the role of psycho-social and environmental influences on this transition, but objective research examining the role of puberty hormones, testosterone in males and oestradiol in females (as biomarkers of puberty on adolescent events is lacking. Neither has the tempo of puberty, the time from onset to completion of puberty within an individual been studied, nor the interaction between age of onset and tempo. This study has been designed to provide evidence on the relationship between reproductive hormones and the tempo of their rise to adult levels, and adolescent behaviour, health and wellbeing. Methods/Design The ARCHER study is a multidisciplinary, prospective, longitudinal cohort study in 400 adolescents to be conducted in two centres in regional Australia in the State of New South Wales. The overall aim is to determine how changes over time in puberty hormones independently affect the study endpoints which describe universal and risk behaviours, mental health and physical status in adolescents. Recruitment will commence in school grades 5, 6 and 7 (10–12 years of age. Data collection includes participant and parent questionnaires, anthropometry, blood and urine collection and geocoding. Data analysis will include testing the reliability and validity of the chosen measures of puberty for subsequent statistical modeling to assess the impact over time of tempo and onset of puberty (and their interaction and mean-level repeated measures analyses to explore for significant upward and downward shifts on target outcomes as a function of main effects. Discussion The strengths of this study include enrollment starting in the earliest stages of puberty, the use of frequent urine samples in addition to annual

Full Text Available Adolescence is a transition period filled with a state of storm and stress. These conditions contribute in increasing the level of adolescents' unhappiness. Each adolescent has a different meaning of sadness depending on their belief. The previous studies stated that Indonesian had positive attitudes towards sad moments. The aim of this research was to discover the meaning of unhappiness among adolescents raised in large cities, rural and urban areas. A total of 426 senior high school students between 1417 years old (urban=151, rural=215, metropolitan=60, were asked to complete open-ended questionnaires by answering the question "What is the meaning behind the sad moments that you describe?" The data was categorized, and then analyzed descriptively. The result shows that 54.2% of the respondents (56.3% of urban, 52.6% of rural, and 55.0% of large city view unhappy moments as a learning process to maturity. There was no significant difference among adolescents indifferent social settings. This finding demonstrated that Indonesian adolescents cope the sad moments by self-reflections and attempt to adjust themselves towards unpleasant situations.
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.
Full Text Available Aims. The purpose of this pilot trial was to determine the efficacy of sleep promotion program to adapt it for the use of adolescents studying in various schools of Mangalore, India, and evaluate the feasibility issues before conducting a randomized controlled trial in a larger sample of adolescents. Methods. A randomized controlled trial design with stratified random sampling method was used. Fifty-eight adolescents were selected (mean age: 14.02 ± 2.15 years; intervention group, n=34; control group, n=24. Self-report questionnaires, including sociodemographic questionnaire with some additional questions on sleep and activities, Sleep Hygiene Index, Pittsburgh Sleep Quality Index, The Cleveland Adolescent Sleepiness Questionnaire, and PedsQL™ Present Functioning Visual Analogue Scale, were used. Results. Insufficient weekday-weekend sleep duration with increasing age of adolescents was observed. The program revealed a significant effect in the experimental group over the control group in overall sleep quality, sleep onset latency, sleep duration, daytime sleepiness, and emotional and overall distress. No significant effect was observed in sleep hygiene and other sleep parameters. All target variables showed significant correlations with each other. Conclusion. The intervention holds a promise for improving the sleep behaviors in healthy adolescents. However, the effect of the sleep promotion program treatment has yet to be proven through a future research. This trial is registered with ISRCTN13083118.
Psychological distress as a mediator of the relationship between childhood maltreatment and sleep quality in adolescence: results from the Maltreatment and Adolescent Pathways (MAP) Longitudinal Study.
McPhie, Meghan L; Weiss, Jonathan A; Wekerle, Christine
Childhood maltreatment represents an important public health concern, as it is often associated with a host of negative outcomes across development. In recent years, researchers have begun to examine the link between negative health-related behaviors and history of childhood maltreatment. The current study considers the relationship between history of childhood maltreatment and sleep disturbances in adolescence. Further, the role of psychological distress is considered as an explanatory link between childhood maltreatment and adolescent sleep disturbances. The current study is a secondary analysis using a subsample (N=73) of child welfare-involved youth who participated in the initial and 2-year time-point of the Maltreatment and Adolescent Pathways (MAP) Longitudinal Study on the variables of interest. Youth reported on lifetime maltreatment experiences, psychological distress, and sleep disturbances, in addition to the other measures administered as part of the larger MAP study protocol. More severe childhood maltreatment was related to increased sleep disturbances during adolescence, and psychological distress was a significant mediator of the childhood maltreatment-adolescent sleep disturbance association. The results demonstrate that a history of childhood maltreatment represents a risk factor for sleep disturbances in adolescence. The findings highlight the importance of inquiring about health-related behaviors in child welfare youth and the need to promote psychological well-being within this population.

Full Text Available Context: Adolescents comprise one-fifth of India’s total population. There is widespread ignorance associated with unprotected sex, contraceptives, among young people. As majority adolescents in slum areas have illiterate and ignorant family backgrounds; they are misguided by the myths. Hence providing sex education for them is the need of the hour. Aims: 1 To assess the knowledge and awareness of adolescents in an urban slum area regarding some aspects of reproductive health. 2 To assess the need of sex education among them. 3 To study the impact of sex education on their knowledge Material and Methods: An interventional study was done on 132 adolescents of urban slum area, selected by simple random sampling. Informed consent was obtained from the participants. Data was collected with the help of structured questionnaire prepared by literature search. Response of adolescents was recorded through questionnaires. A sensitization workshop was organized as intervention. The same questionnaire was given to them and the effect of intervention was assessed. Statistical analysis of data was done using percentage, proportion and appropriate tests of significance. Result and Conclusions: Only 31.06% adolescents had discussed the topic of reproductive health with some or other person and out of them friends were the major sources (39.2% of information. Only 38.63% knew the hazards of teenage pregnancy which significantly rose to 89.4% after intervention workshop. The study concludes that the slum adolescents profoundly lack adequate knowledge of sexuality related matters. Even before intervention workshop, unmet need of reproductive health education was 59.1% and 93.93% was the felt need in the post test.

Full Text Available Background: Adolescence, a period of transition between childhood and adulthood, occupies a crucial position in the life of human beings. The primary causes of under nutrition in India are its large population, socio-economic differences and inadequate access to health facilities. Nutritional assessments among adolescents are important as they are the future parents and constitute a potentially susceptible group. Studies on the assessment of nutritional status of adolescents are less in number and a National database has not yet been developed. Methods: The present hospital based cross sectional study was conducted in year 2013 among 344 rural adolescents of 10-19 years age (166 boys and 178 girls attending the outpatient department at rural health training centre (RHTC Dhaura Tanda, district Bareilly, Uttar Pradesh, belonging to the Muslim and Hindu caste communities. The nutritional status was assessed in terms of under nutrition (weight-for-age below 3rd percentile, stunting (Height-for-age below 3rd percentile and thinness (BMI-for-age below 5th percentile. Diseases were accepted as such as diagnosed by pediatrician, skin specialist and medical officer. Results: The prevalence of underweight, stunting and thinness were found to be 32.8%, 19.5% and 26.7% respectively. The maximum prevalence of malnutrition was observed among early adolescents (28%-47% and the most common morbidities were URTI (38.6%, diarrhea (16.8%, carbuncle / furuncle (16% and scabies (9.30%. Conclusion: The study concluded that the most common morbidities among adolescents were related to nutrition and personal hygiene. Regular health programmes should focus to educate and promote health among adolescent. [Int J Res Med Sci 2014; 2(2.000: 620-624

Background Research shows that parents have an immense influence over their children’s behavior during adolescence. Adolescents who grow up with parents who are addicted to drugs and alcohol are more likely to turn to self-destructive behaviors such as suicide attempts. Because addiction in Iran is a primarily masculine phenomenon and in traditional Iranian culture, the father is responsible for family affairs and is recognized as the family provider, paternal addiction affects adolescent children. However, the impact of this type of parental addiction on adolescent suicide attempts has received little attention. Objectives This study was conducted to assess the impact of paternal addiction on adolescent suicide attempts. Patients and Methods This was a qualitative study that used a grounded theory approach. Thirteen participants, from two hospitals in Shiraz (southern Iran), were interviewed. We used purposeful sampling, followed by theoretical sampling. Data were collected from in-depth semi-structured interviews. Data analysis was done using Strauss and Corbin’s (1998) approach, followed by the constant comparative method. Results The mean age of the adolescents was 15.75 ± 1.83, and all of them were single. Five main themes were extracted from the data: mental health problems, relationship problems, financial problems, family problems, and imitation of risky behaviors. Conclusions The findings suggest that in addition to the need to consider paternal addiction in health care plans, it is also necessary to pay attention to other family members, including the adolescents themselves. Health care providers, including nurses, can use the findings from this study for the purposes of prevention and education. PMID:27818961
Full Text Available Background: Adolescent problems are increasing over the years and need special consideration. We, as health care providers, need to focus on young people as investing in their health today will reap rich rewards tomorrow. Methods: All the adolescents presenting with various gynaecological problems were evaluated by detailed history taking and thorough clinical examination after taking an informed consent and explaining them our objective. After examination, adolescent girls were given education by means of slide show about menstruation, care during menses, nutritional diet and prevention of anaemia. Results: Majority of adolescents had regular menstrual pattern. Oligomenorrhoea was the most prevalent abnormality of menstrual pattern in these adolescents. 15.58% adolescents had presented with breast problems like mastalgia, lump in breast, etc. Majority of adolescents studied were aware of the physical signs of puberty (77.25% and HIV (74.14%. But very few adolescents were aware of the physiology involved in menstruation. Around half of all the adolescents were seen to follow proper menstrual hygiene. Conclusions: Healthy adolescence, the need of the hour. [Int J Reprod Contracept Obstet Gynecol 2014; 3(4.000: 1010-1014

The prevalence of pediatric overweight has increased dramatically over the past three decades, likely due to changes in food intake as well as physical activity. Therefore, information examining eating patterns among children and adolescents is needed to illuminate which aspects of eating behavior require modification to prevent and treat pediatric overweight. Because child self-report and parent-report of children's eating habits are often inconsistent and limited by recall and other biases,...

Full Text Available Se estudiaron los hijos de 25 adolescentes extremas (13-15 años, 77 intermedias (16-17 años, 88 limítrofes (18-19 años y 100 controles mayores (20-30 años. Los hijos de las extremas tuvieron mayores porcentajes de morbilidad, lo mismo que los hijos de todas las adolescentes en comparación con los de las controles (p < 0.05. Entre la morbilidad resaltó el mayor grado de asfixia perinatal en los hijos de las adolescentes extremas y las limítrofes. El peso, la talla, el perímetro cefálico y el índice de Rohrer fueron similares en los cuatro grupos. No se detectó asociación entre la morbilidad de los niños y las siguientes variables maternas: El estado civil, la morbilidad y el rechazo al embarazo. La mortalidad global de los hijos de las adolescentes fue significativamente mayor que la de los controles, pero a costa de los hijos de las intermedias (p < 0.05. En conclusión, tanto la morbilidad general como la mortalidad son superiores entre los hijos de las adolescentes más jóvenes. Morbidity was studied in neonate infants of 25 young adolescent mothers (13 to 15 year-old, 77 mid adolescent mothers (16 to 17 year old, 88 borderline adolescent mothers (18 to 19 year-old and 100 post adolescent ones (20 to 30 year old. Young adolescents' children as well as children from all adolescent mothers showed higher morbidity rates as compared to those of controls (p < 0.05. A higher frequency of perinatal asphyxia in neonates of both young and borderline adolescents was evident. Weight, height, cephalic perimeter and Rohrer index were similar in the four groups. No correlation was observed between neonates' morbidity and the following maternal variables: marital status, morbidity and pregnancy rejection. Overall mortality of adolescents' children, particularly of those of mid adolescent mothers, was significantly higher than that of controls (p < 0.05}. In conclusion, and inverse correlation was found between neonates' overall morbidity and

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

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

Full Text Available This study investigates the relationship between three different cognitive processes underlying the Iowa Gambling Task (IGT and adolescent smoking behaviors in a longitudinal study. We conducted a longitudinal study of 181 Chinese adolescents in Chengdu City, China. The participants were followed from 10th grade to 11th grade. When they were in the 10th grade (Time 1, we tested these adolescents’ decision-making using the Iowa Gambling Task and working memory capacity using the Self-ordered Pointing Test (SOPT. Self-report questionnaires were used to assess school academic performance and smoking behaviors. The same questionnaires were completed again at the one-year follow-up (Time 2. The Expectancy-Valence (EV Model was applied to distill the IGT performance into three different underlying psychological components: (i a motivational component which indicates the subjective weight the adolescents assign to gains versus losses; (ii a learning-rate component which indicates the sensitivity to recent outcomes versus past experiences; and (iii a response component which indicates how consistent the adolescents are between learning and responding. The subjective weight to gains vs. losses at Time 1 significantly predicted current smokers and current smoking levels at Time 2, controlling for demographic variables and baseline smoking behaviors. Therefore, by decomposing the IGT into three different psychological components, we found that the motivational process of weight gain vs. losses may serve as a neuropsychological marker to predict adolescent smoking behaviors in a general youth population.

Full Text Available Purpose. The anthropometric status and growth of adolescents living in challenging conditions such as slums are insufficiently studied. The purpose here was to describe anthropometric characteristics and nutritional status of adolescents from urban slums of India and to study the factors affecting it. Methods. Anthropometric, socioeconomic and dietary habit data were collected using structured questionnaires of six hundred adolescents aged 10–19 years by house-to-house survey conducted in two randomly selected slums of Nashik, Western India. The growth of adolescents was compared using WHO and Indian reference populations. Mixed effects logistic regression models were used to examine associations between anthropometric measures and income, mother’s education, household size, and dietary intake. Results. Prevalences of stunting and thinness were lower using the Indian reference population compared to that of WHO. Stunting was more prevalent than thinness in the study subjects, and boys suffered more than girls. The effect of age on stunting was different among boys than girls. A mother’s education was highly significantly associated with both stunting and thinness in both sexes. Household size and income were significantly associated with the nutritional status of girls. Conclusions. Educating mothers about the nutritional needs of adolescents may help to improve adolescents’ anthropometric profile and future health.

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

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

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.

The present study aims to investigate the longitudinal impact of situational Internet use on future cigarette smoking and alcohol use among male and female adolescents. A Northern Taiwanese cohort sample of adolescents with no prior use of cigarettes (n=1445) or alcohol (n=1468) was surveyed at age 16 and again 4 years later. Information regarding where, why, and length of time spent using the Internet was gathered from the 16-year-old participants. Outcome information regarding cigarette/alcohol use was gathered via a follow-up questionnaire at age 20. Multivariate regressions were used to incorporate peer, individual and family characteristics as measured at age 16 and create models of future cigarette and alcohol use at age 20. The analyses demonstrated that adolescent Internet use, particularly where such use took place, has a significant impact on future cigarette smoking and alcohol use, adjusted for conventional factors, and its relationship differs significantly by gender. Female adolescents with Internet café use appear to be especially likely to develop these two risky behaviors. The why of Internet use is also a predictor of future cigarette smoking. Finally, time spent using the Internet is significantly related to alcohol use; greater use of the Internet is associated with higher levels of drinking. The results revealed that different risky behaviors are differentially influenced by separate components of adolescent Internet use. These findings suggest that programs aimed at promoting adolescent health could potentially benefit Taiwanese adolescents by including components related to situational Internet use and taking gender into consideration.

Full Text Available Abstract Background Chronic pain is prevalent among young people and negatively influences their quality of life. Furthermore, chronic pain in adolescence may persist into adulthood. Therefore, it is important early on to promote the self-management skills of adolescents with chronic pain by improving signaling, referral, and treatment of these youngsters. In this study protocol we describe the designs of two complementary studies: a signaling study and an intervention study. Methods and design The signaling study evaluates the Pain Barometer, a self-assessed signaling instrument for chronic pain in adolescents. To evaluate the feasibility of the Pain Barometer, the experiences of youth-health care nurses will be evaluated in semi-structured interviews. Also, we will explore the frequencies of referral per health-care provider. The intervention study evaluates Move It Now, a guided self-help intervention via the Internet for teenagers with chronic pain. This intervention uses cognitive behavioural techniques, including relaxation exercises and positive thinking. The objective of the intervention is to improve the ability of adolescents to cope with pain. The efficacy of Move It Now will be examined in a randomized controlled trial, in which 60 adolescents will be randomly assigned to an experimental condition or a waiting list control condition. Discussion If the Pain Barometer is proven to be feasible and Move It Now appears to be efficacious, a health care pathway can be created to provide the best tailored treatment promptly to adolescents with chronic pain. Move It Now can be easily implemented throughout the Netherlands, as the intervention is Internet based. Trial registration Dutch Trial Register NTR1926
Full Text Available Abstract Background There is a lack of population-based long-term longitudinal research on mental health status and functional physical/somatic symptoms. Little is known about the long-term mental health outcomes associated with somatic symptoms or the temporal relationship between depression and such symptoms. This 15-year study followed up adolescents with depression and matched controls, screened from a population-based sample, who reported different numbers of somatic symptoms. Methods The total population of 16–17-year-olds in Uppsala, Sweden, was screened for depression in 1991–1993. Adolescents who screened positive and an equal number of healthy controls took part in a semi-structured diagnostic interview. In addition, 21 different self-rated somatic symptoms were assessed. Sixty-four percent of those adolescents participated in a follow-up structured interview 15 years later. Results Somatic symptoms in adolescence predicted depression and other adult mental disorders regardless of the presence of adolescent depression. In adolescents with depression, the number of functional somatic symptoms predicted, in a dose response relationship, suicidal behavior, bipolar episodes, and psychotic episodes as well as chronic and recurrent depression. Contrary to expectations, the somatic symptoms of abdominal pain and perspiration without exertion better predicted depression than all DSM-IV depressive symptoms. Abdominal pain persisted as an independent strong predictor of depression and anxiety, even after controlling for other important confounders. Conclusions Somatic symptoms in adolescence can predict severe adult mental health disorders. The number of somatic symptoms concurrent with adolescent depression is, in a stepwise manner, linked to suicidal attempts, bipolar disorders, psychotic disorders, and recurrent and chronic depression. These findings can be useful in developing treatment guidelines for patients with somatic symptoms.

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

The main purpose of this study was to investigate the relationship between masturbatory knowledge and masturbatory attitudes among Taiwan adolescents. This study was based on a structured questionnaire survey that used the Adolescent Masturbatory Knowledge Inventory (AMKI) and the Adolescent Negative Attitude toward Masturbation Inventory (ANAMI). Subjects were recruited from the third grade of high school and vocational school students aged 17-18 living in Kaohsiung (southern Taiwan) using stratified and cluster sampling approaches. Seven hundred and eighty questionnaires were sent out, with a 96.8% response rate. A total of 95.3% of male subjects and 30.3% of female subjects reported having masturbation experience. Masturbatory knowledge was significantly related to the variables "school system", "frequency of viewing pornographic media", "status of being sexually active", and "conversation about sex with friends". Masturbatory attitudes were significantly associated with the same variables as well as with gender and masturbatory behavior. Masturbatory attitudes were positively correlated with masturbatory knowledge. The school system explained 15.4% of masturbatory knowledge variance. Masturbatory knowledge, masturbatory behavior, frequency of viewing pornographic media and status of being sexually active explained 39.5% of masturbatory attitude variance. In conclusion, adolescents in Taiwan hold positive attitudes toward masturbation and reported having insufficient knowledge regarding masturbation. Results can assist school staffs and parents to gain a deeper understanding of adolescents' knowledge about and attitudes toward masturbation.

The aim of this study is to prospectively investigate whether exposure to radiofrequency electromagnetic fields (RF-EMF) emitted by mobile phones and other wireless communication devices is related to behavioural problems or concentration capacity in adolescents. The HERMES (Health Effects Related to Mobile phonE use in adolescentS) study sample consisted of 439 Swiss adolescents aged 12-17 years. Behavioural problems were assessed using the Strengths and Difficulties Questionnaire (SDQ), concentration capacity of the adolescents was measured by means of a standardized computerized cognitive test named FAKT. Cross-sectional and longitudinal (1year of follow-up) analyses were performed to investigate possible associations between behavioural problems and concentration capacity and different exposure measures: self-reported and operator-recorded wireless communication device use, cumulative RF-EMF brain and whole body dose and measured personal RF-EMF exposure. In the cross-sectional analyses behavioural problems were associated with several self-reported wireless device use measures but not operator-recorded mobile phone use measures, concentration capacity was associated with several self-reported and operator-recorded exposures. The longitudinal analyses point towards absence of associations. The lack of consistent exposure-response patterns in the longitudinal analyses suggests that behavioural problems and concentration capacity are not affected by the use of wireless communication devices or RF-EMF exposure. Information bias and reverse causality are likely explanations for the observed cross-sectional findings.

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

AIMS: This study seeks to examine whether contextual factors influence adolescents' daily smoking. A focus was placed on three modifiable policies operating at a national level, non-smoking policy at educational facilities, price and minimum age for buying tobacco. DESIGN: This study is based...... in Europe, Israel and North America. Data were analysed with multi-level hierarchical regression models. FINDINGS: The study found large differences in the prevalence of daily smoking among adolescents, and also large differences between boys and girls within some countries. The study found that smoking...... bans in schools were associated with lower odds ratios of daily smoking, which was the one positive association in the study. The study found no association between cigarette prices and adolescent daily smoking prevalence, and also the somewhat unexpected finding that having an age limit for allowing...

Various definitions are used to define metabolic syndrome in adolescents. This study aimed to compare, in terms of prevalence and differences, five frequently used definitions for this population: International Diabetes Federation, National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP) modified by Cook, pediatric American Heart Association (AHA), World Health Organization, and Jolliffe and Janssen. A sample of 1004 adolescents (12.5-17.0 years) from the Healthy Lifestyle in Europe by Nutrition in Adolescence (HELENA) study was considered. The components of the definitions (waist circumference/BMI, plasma lipids, glycemia, and blood pressure) were applied, and definitions were compared by using crosstabs, sensitivity, specificity, and kappa coefficient. The prevalence of metabolic syndrome varied from 1.6 to 3.8% depending on the used definitions. Crosstabs comparing the definitions showed the fewest cases being misclassified (having metabolic syndrome or not) between NCEP-ATP and AHA. Analyses for kappa coefficient, sensitivity, and specificity confirmed this finding.

In a few years the Internet has become one of the most relevant means of socialization and entertainment for Italian adolescents. Studies have established a correlation between poor interpersonal relationship, poor cognitive coping strategies and Problematic Internet Use. The aim of the research was to study the characteristics and correlates of Problematic Internet Use in an Italian sample of adolescents. 98 Italian adolescents aged 14-19 were administered checklists assessing Problematic Internet Use, quality of interpersonal relationships, and cognitive-driven coping strategies. Of the participants, 36.7% are characterized by Problematic Internet Use. This subsample showed poorer interpersonal relationships and cognitive coping strategies compared to the non-problematic subsample. Overall quality of interpersonal relationships and cognitive coping strategies were found to be predictors of the level of Internet Problematic Use.

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

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

This study investigated whether insecure attachment is associated with poorer outcomes at 6-month follow-up in adolescents who self-harm. At baseline the Child Attachment Interview was administered to 52 adolescents (13-17 years) referred to specialist child and adolescent mental health services and with a recent history of self-harm. Participants also completed self-report measures of self-harm, peer attachment, anxiety, and depression and were administered the means end problem-solving task. Self-harm behavior and problem-solving skills were assessed again at 6-month follow-up. At baseline, 14 (27%) were securely attached to their mothers. In the 49 (94%) adolescents followed-up, those with insecure maternal attachment and insecure peer attachment were more likely to have repeated self-harm. In addition, securely attached adolescents showed greater improvement in problem-solving skills. These findings indicate that secure maternal and peer attachments may help recovery from self-harm, possibly by supporting the acquisition of problem-solving skills, and highlights the importance of social connections and attachments for youth with a history of self-harm.

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

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

In the psychological literature, many studies have investigated the neuropsychological and behavioral changes that occur developmentally during adolescence. These studies have consistently observed a deficit in the decision-making ability of children and adolescents. This deficit has been ascribed to incomplete brain development. The same deficit has also been observed in adult problem and pathological gamblers. However, to date, no study has examined decision-making in adolescents with and without gambling problems. Furthermore, no study has ever examined associations between problem gambling, decision-making, cognitive distortions and alcohol use in youth. To address these issues, 104 male adolescents participated in this study. They were equally divided in two groups, problem gamblers and non-problem gamblers, based on South Oaks Gambling Screen Revised for Adolescents scores. All participants performed the Iowa gambling task and completed the Gambling Related Cognitions Scale and the alcohol use disorders identification test. Adolescent problem gamblers displayed impaired decision-making, reported high cognitive distortions, and had more problematic alcohol use compared to non-problem gamblers. Strong correlations between problem gambling, alcohol use, and cognitive distortions were observed. Decision-making correlated with interpretative bias. This study demonstrated that adolescent problem gamblers appear to have the same psychological profile as adult problem gamblers and that gambling involvement can negatively impact on decision-making ability that, in adolescence, is still developing. The correlations between interpretative bias and decision-making suggested that the beliefs in the ability to influence gambling outcomes may facilitate decision-making impairment.

Combined analyses from 2 open-label, phase-1 studies-the pharmacokinetic profile of tramadol and its metabolite (M1) following a single oral dose of tramadol extended release (ER) (25 to 100 mg) in children (7 to 11 years old; study 1: n = 37) and adolescents (12 to 17 years old; study 2: n = 38) with painful conditions-were historically compared with that of healthy adults following similar dosing. The dose-normalized area under the curve (DN AUC0-24h ) and maximum concentration (DN Cmax ) of tramadol and of M1 in children and in adolescents were lower than those in adults (children vs adults: tramadol, DN AUC0-24h 82.19%; DN Cmax 80.38%, P = .0031; M1, DN AUC0-24h 51.19%, DN Cmax 52.68%, P < .0001; adolescents vs adults: tramadol, DN AUC0-24h 89.56%, DN Cmax 84.01%; M1, DN AUC0-24h 85.28%, DN Cmax 83.03%, P = .0004). The arithmetic mean terminal elimination t1/2 of tramadol in children and adolescents was comparable to that in adults (children 8.4 hours; adolescents 8.5 hours; adults 7.9 hours). The most frequently reported (≥5% of participants) treatment-emergent adverse events in children included headache, upper abdominal pain and constipation, and in adolescents were headache, nausea, dizziness, and stomach discomfort. Multiple factors may have contributed to these observations, including a higher proportion of children (56%) who may have a lower activity of CYP2D6, resulting in reduced clearance of tramadol.

Objective Malocclusion is a highly prevalent condition, affecting 20–60% of adolescents worldwide. Although its treatment is often expensive and unaffordable for disadvantaged individuals, few studies have examined the relationship between malocclusion and socioeconomic status. We investigated the prevalence of malocclusion among Mongolian adolescents and its association with maternal education in a community-based sample in Mongolia. Design Cross-sectional study. Settings 2 large secondary schools with different backgrounds in Ulaanbaatar, Mongolia. Participants Complete dental casts of 557 randomly recruited Mongolian schoolchildren aged 11–16 years were evaluated using the Dental Health Component of the Index of Orthodontic Treatment Need to dichotomise orthodontic treatment requirements. Exclusion criteria were the presence of orthodontic treatment history and absence of maternal educational status. Questionnaires were administered to caregivers to assess socioeconomic status. Poisson regression analysis was performed to examine the association between malocclusion and maternal educational status. Results The prevalence of malocclusion requiring orthodontic treatment among all adolescents was 35.2% (95% CI 31.2 to 39.2). In the unadjusted analysis, the prevalence ratio (PR) for malocclusion was higher (PR=1.46; 95% CI 0.96 to 2.20) among adolescents of mothers with a high educational background than among those of mothers with a low educational background. After adjusting for covariates, the PR remained significantly higher (PR=1.72; 95% CI 1.06 to 2.82) among adolescents of mothers with a high educational background. Other socioeconomic status variables, including family income and the educational level of the father, showed no association with malocclusion. Conclusions These findings suggest that malocclusion requiring orthodontic treatment in adolescents is more prevalent among children of mothers with high levels of education. Further studies are

Introduction: Current evidence suggests that ghrelin could contribute to the development of metabolic syndrome (MetS) in adults, but limited experience exists in adolescents. This study aims to explore the association of ghrelin levels with the MetS components among Iranian adolescents. Methods: In this case-control study, 32 adolescents with MetS and 148 healthy controls were selected randomly from the childhood and Adolescence Surveillance and Prevention of Adult Non communicable disease (CASPIAN-III) study. MetS was defined according to the Adult Treatment Panel III (ATP III) criteria modified for children and adolescents. Anthropometric measures (including body mass index [BMI], waist circumference [WC] and waist to height ratio [WHtR]), blood pressure (BP) and biochemical data (including fasting blood sugar [FBS], triglyceride [TG], high-density lipoprotein cholesterol [HDL-C], low-density lipoprotein cholesterol [LDL-C], total cholesterol [TC] and gerlin) were measured. Results: Total ghrelin level was significantly higher in students without MetS compared to those with MetS (748.89 ± 85.04 vs. 728.72 ± 90.36 [pg/mL]; P < 0.001). Significant negative correlations were seen between ghrelin levels and BMI, WC, WHtR, TG, and TC. Ghrelin had also relatively strong inverse correlations with FBS (r = −0.59, P< 0.001), LDL-C (r = −0.56, P < 0.001), and positive correlation with HDL-C (r = 0.60, P < 0.001). Compared with the children with MetS, in those without MetS, ghrelin was significantly associated with HDL-C and LDL-C. A decreasing trend was observed in the mean ghrelin level across increasing number of MetS components (P for trend <0.001). Conclusion: We observed a relationship between ghrelin concentration and MetS components in adolescents. PMID:27777695

While physical activity is beneficial for youth with developmental disabilities, little is known about those individuals' fitness profile and levels of activity. Therefore the purpose of this study was to investigate the physical fitness profile and physical activity level of 30 adolescents with and without Asperger syndrome (AS). Evaluations were done using the Eurofit physical fitness test and the Baecke Habitual Physical Activity questionnaire. A 2 x 2 MANOVA indicated that adolescents with AS scored significantly lower than the comparison group on all physical fitness subtests, including balance, coordination, flexibility, muscular strength, running speed, and cardio-respiratory endurance (p < .001). Adolescents with AS were also less physically active (p < .001). Engagement in physical activities is therefore recommended.

Facebook has been used in health research, but there is a lack of literature regarding how Facebook may be used to recruit younger adolescents. A Facebook Page was created for an adolescent cohort study on the effects of puberty hormones on well-being and behaviour in early adolescence. Used as a communication tool with existing participants, it also aimed to alert potential participants to the study. The purpose of this paper is to provide a detailed description of the development of the study Facebook Page and present the fan response to the types of posts made on the Page using the Facebook-generated Insights data. Two types of posts were made on the study Facebook Page. The first type was study-related update posts and events. The second was relevant adolescent and family research and current news posts. Observations on the use of and response to the Page were made over 1 year across three phases (phase 1, very low Facebook use; phase 2, high Facebook use; phase 3, low Facebook use). Most Page fans were female (88.6%), with the largest group of fans aged between 35 and 44 years. Study-related update posts with photographs were the most popular. This paper provides a model on which other researchers could base Facebook communication and potential recruitment in the absence of established guidelines.

A sample of 63 adolescents with schizoid personality disorder, aged 15-17 years, 58 males and 5 females, was followed up for a period of 3-8 years and re-examined at the age of 20-25. The patients were examined in a psychoneurologic out-patient center due to social maladaptation. The follow-up study revealed the improvement of social adaptation with an extremely low percent (5%) of schizophrenia manifestations. A number of clinical factors significant for the future social functioning of schizoid adolescents was found. A strategy of psychocorrection and sociotherapeutic care for the patients is worked out.
Full Text Available Studies examining development of eating behavior in different age groups are reviewed. Determinants of disordered eating attitudes from infancy to adolescent are particularly examined. Family environment and social context are general factors. Knowledge, attitudes and food preferences are individual factors. Eating habits in infancy, early childhood and preschool period related to parent’s eating attitudes; peers and social context are dominant in school period and adolescents. The most effective strategy is to prevent disordered eating attitudes in early childhood. Restriction and pressure are not effective strategies in developing healthy eating.
Full Text Available Background/Aims: Chronic medical illness is a significant risk factor for the development of psychiatric disorders. The aims of the study were: to investigate the level of anxiety in children with chronic kidney disease (CKD and to identify factors associated with the presence of that emotional problem. Methods: CKD children on hemodialysis (HD, n=22, peritoneal dialysis (PD, n=20, and on conservative treatment (CT, n=95 were enrolled in the study. We used State-Trait Anxiety Inventory (STAI for adolescents and STAI-C for children. Socio-demographic and physical factors were assessed. Results: There was a significantly higher level of anxiety-state among HD children (8-12 years compared with other groups of participants of the same age and Polish population norms. The level of anxiety among adolescents (13-18 years, both anxiety-state and anxiety-trait, was significantly higher in the HD group compared with other groups, which did not differ among themselves. In the HD adolescents, there was a correlation between the anxiety-state and the duration of the disease as well as with the number of hospitalizations. PD adolescents in the mainstream education had higher levels of anxiety-state and anxiety-trait compared with home schooled patients. Conclusions: Even though children and adolescents with CKD are at risk of developing a variety of emotional disorders, the level of anxiety among the researched group, with the exception of HD patients, was not significantly different than the level of anxiety among healthy subjects. Adolescents on HD who present a high level of anxiety should undergo long-term psychological treatment.
Full Text Available Background: Worldwide prevalence of overweight and obesity is increasing and its consequences prompted the WHO to designate obesity as a global epidemic in 2002. Being overweight is a risk factor for significant illness, especially diabetes and hypertension in adult life. Objectives : To study the blood pressure and blood sugar levels and lifestyle parameters in adolescence and comparison with body mass index. Materials and Methods: In a prospective case control study, out of the 1000 screened, a total of 200 adolescents were considered out of which 100 were with high body mass index (BMI and the other 100 were with normal BMI. Height, weight, BMI, waist hip ratio (WHR, blood pressure (BP, BSL, and associated risk factors like physical activity, fast food consumption, and computer/television watching were measured and screened. Results and Observations: 109 (54.5% males and 91 (45.5% females were included. Maximum number [90 (45%] of adolescents screened were in the age group of 17-19 years, while 54 (27% and 56 (28% adolescents were in the age group of 10-13 years and 14-16 years, respectively. According to CDC charts 2000, prevalence of overweight was 24% which was double when compared to WHO charts 2007. There was significant difference in prevalence of obesity; according to CDC chart it was 26%, whereas according to WHO chart it was 39%. The difference in blood pressures between cases and controls as per both CDC and WHO charts was found to be statistically significant (P 0.05 with BMI. Conclusion: The adolescents seem to have become heavier owing to environmental influences on growth patterns. So, a consideration should be given to shift the cut-offs for overweight and obesity to higher BMI percentiles if recent growth charts are to be followed. Adolescents with a BMI above the 95 >th percentile (obese are most likely to have obesity-related health risks.

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 Although there is concern about increasing hearing loss in adolescents caused by leisure noise exposure, prevalence data are scarce. In an US study, about 16-17% of adolescents were affected by audiometric notches. To estimate the prevalence of audiometric notches in adolescents in Germany, baseline data of the cohort study Ohrkan, recruitment during the school years 2009/2010 and 2010/2011 were analyzed. All students in grade 9 visiting any school in the city of Regensburg were eligible for participation. Data was collected via standardized questionnaires from students and their parents. In addition, students were asked to visit the University Clinics of Regensburg for ear examination including a tympanogram and the determination of hearing thresholds in air conduction audiometry. The prevalence of audiometric notches was determined in students with normal tympanogram in both ears and complete audiometry data. Audiometric notches were defined according to criteria used to analyse US data. Overall, 2149 students (1158 girls, 991 boys mainly aged 15-16 years of the 3846 eligible adolescents (56% participated. Among the 1843 adolescents with complete audiometry and tympanometry data, the prevalence of audiometric notches was 2.4% (95% confidence interval 1.7-3.1%. We could not confirm the high prevalence of audiometric notches as reported in National Health and Nutrition Examination Surveys for adolescents in the US. Differences in prevalence might be at least partly due to methodical differences in audiometry. Even if empirical evidence is presently ambiguous, it is reasonable to educate young people about the potential risks of high leisure noise exposure.
Full Text Available OBJECTIVE: The objective of this study was to identify factors influencing eating behavior of Ecuadorian adolescents - from the perspective of parents, school staff and adolescents - to develop a conceptual framework for adolescents' eating behavior. STUDY DESIGN: Twenty focus groups (N=144 participants were conducted separately with adolescents aged 11-15 y (n (focus groups=12, N (participants=80, parents (n=4, N=32 and school staff (n=4, N=32 in rural and urban Ecuador. A semi-structured questioning route was developed based on the 'Attitude, Social influences and Self-efficacy' model and the socio-ecological model to assess the relevance of behavioral and environmental factors in low- and middle-income countries. Two researchers independently analyzed verbatim transcripts for emerging themes, using deductive thematic content analysis. Data were analyzed using NVivo 8. RESULTS: All groups recognized the importance of eating healthily and key individual factors in Ecuadorian adolescents' food choices were: financial autonomy, food safety perceptions, lack of self-control, habit strength, taste preferences and perceived peer norms. Environmental factors included the poor nutritional quality of food and its easy access at school. In their home and family environment, time and convenience completed the picture as barriers to eating healthily. Participants acknowledged the impact of the changing socio-cultural environment on adolescents' eating patterns. Availability of healthy food at home and financial constraints differed between settings and socio-economic groups. CONCLUSION: Our findings endorse the importance of investigating behavioral and environmental factors that influence and mediate healthy dietary behavior prior to intervention development. Several culture-specific factors emerged that were incorporated into a conceptual framework for developing health promotion interventions in Ecuador.

Behavioral responses to, and the neural processing of, rewards change dramatically during adolescence and may contribute to observed increases in risk-taking during this developmental period. Functional MRI (fMRI) studies suggest differences between adolescents and adults in neural activation during reward processing, but findings are contradictory, and effects have been found in non-predicted directions. The current study uses an activation likelihood estimation (ALE) approach for quantitative meta-analysis of functional neuroimaging studies to: (1) confirm the network of brain regions involved in adolescents' reward processing, (2) identify regions involved in specific stages (anticipation, outcome) and valence (positive, negative) of reward processing, and (3) identify differences in activation likelihood between adolescent and adult reward-related brain activation. Results reveal a subcortical network of brain regions involved in adolescent reward processing similar to that found in adults with major hubs including the ventral and dorsal striatum, insula, and posterior cingulate cortex (PCC). Contrast analyses find that adolescents exhibit greater likelihood of activation in the insula while processing anticipation relative to outcome and greater likelihood of activation in the putamen and amygdala during outcome relative to anticipation. While processing positive compared to negative valence, adolescents show increased likelihood for activation in the posterior cingulate cortex (PCC) and ventral striatum. Contrasting adolescent reward processing with the existing ALE of adult reward processing reveals increased likelihood for activation in limbic, frontolimbic, and striatal regions in adolescents compared with adults. Unlike adolescents, adults also activate executive control regions of the frontal and parietal lobes. These findings support hypothesized elevations in motivated activity during adolescence.
Full Text Available BACKGROUND: Although important to public policy, there have been no rigorous evidence syntheses of the long-term consequences of late adolescent drinking. METHODS AND FINDINGS: This systematic review summarises evidence from general population cohort studies of drinking between 15-19 years old and any subsequent outcomes aged 20 or greater, with at least 3 years of follow-up study. Fifty-four studies were included, of which 35 were assessed to be vulnerable to bias and/or confounding. The principal findings are: (1 There is consistent evidence that higher alcohol consumption in late adolescence continues into adulthood and is also associated with alcohol problems including dependence; (2 Although a number of studies suggest links to adult physical and mental health and social consequences, existing evidence is of insufficient quality to warrant causal inferences at this stage. CONCLUSIONS: There is an urgent need for high quality long-term prospective cohort studies in order to better understand the public health burden that is consequent on late adolescent drinking, both in relation to adult drinking and more broadly. Reducing drinking during late adolescence is likely to be important for preventing long-term adverse consequences as well as protecting against more immediate harms.

Full Text Available Abstract Background Evidence suggests possible synergetic effects of multiple lifestyle behaviors on health risks like obesity and other health outcomes. Therefore it is important to investigate associations between dietary and physical activity behavior, the two most important lifestyle behaviors influencing our energy balance and body composition. The objective of the present study is to describe the relationship between energy, nutrient and food intake and the physical activity level among a large group of European adolescents. Methods The study comprised a total of 2176 adolescents (46.2% male from ten European cities participating in the HELENA (Healthy Lifestyle in Europe by Nutrition in Adolescence study. Dietary intake and physical activity were assessed using validated 24-h dietary recalls and self-reported questionnaires respectively. Analyses of covariance (ANCOVA were used to compare the energy and nutrient intake and the food consumption between groups of adolescents with different physical activity levels (1st to 3rd tertile. Results In both sexes no differences were found in energy intake between the levels of physical activity. The most active males showed a higher intake of polysaccharides, protein, water and vitamin C and a lower intake of saccharides compared to less active males. Females with the highest physical activity level consumed more polysaccharides compared to their least active peers. Male and female adolescents with the highest physical activity levels, consumed more fruit and milk products and less cheese compared to the least active adolescents. The most active males showed higher intakes of vegetables and meat, fish, eggs, meat substitutes and vegetarian products compared to the least active ones. The least active males reported the highest consumption of grain products and potatoes. Within the female group, significantly lower intakes of bread and cereal products and spreads were found for those reporting to

Full Text Available Background: Adolescence is a transition phase through which a child matures into an adult. The physical changes in the human body are from infant to child to adolescence to adult to old age. All phases of life behave like a coin with both good and bad facets attached to each phase of life. Aims & Objectives: 1. To study perception and awareness regarding pubertal changes among school going adolescent boys. 2. To study the association between education and perceived pubertal problems among study subjects. Material & Methods: The study was conducted among male students of senior secondary schools of community development block Beri in one year. The study universe comprised of students in middle and late adolescence (aged 14-18 years studying in 9th to 12th classes of the senior secondary schools in the area. A total of 1000 male students were selected from these schools which were more than the required sample size of 891. Results: The study found that 42.66% students and a half (50% of students of class 9th & 10th and class 11th & 12th respectively considered that pubertal changes as a normal phenomenon. The majority of students admitted practicing masturbation and felt shy and guilty for practicing masturbation, also students felt fatigued after night emission. Conclusions: The study concludes that adolescent’s sexuality which often causes controversy and concern among adults is least discussed with them during adolescence. The reasons for this may be many, including moral grounds or because of concomitant health risks and threats to wellbeing.

Depression during adolescence is critical to the individual's own development. Hence, identifying individuals with high-risk depression at an early stage is necessary. This study aimed to identify childhood emotional and behavioral risk factors related to depressive symptoms in Korean adolescents through a longitudinal study. The first survey took place from 1998 to 2000, and a follow-up assessment conducted in 2006, as the original participants reached 13-15 yr of age. The first assessment used the Korean version of Child Behavior Checklist and a general questionnaire on family structure, parental education, and economic status to evaluate the participants. The follow-up assessment administered the Korean Children's Depression Inventory. Multiple regression analysis revealed that childhood attention problems predicted depressive symptoms during adolescence for both boys and girls. For boys, family structure also predicted adolescent depressive symptoms. This study suggests that adolescents with attention problems during childhood are more likely to experience depressive symptoms.

Full Text Available BACKGROUND Tobacco is the most common substance used across the world. DALY’s lost due to tobacco consumption is 4.1. Substance use like tobacco and alcohol among adolescents can lead to a variety of detrimental consequences. Recent studies by WHO have found that tobacco use is increasing among school children in India and a sizeable proportion of them experiment with drugs quite early in life. OBJECTIVES 1. To study the prevalence of tobacco consumption among tribal adolescents. 2. To study the different modes of tobacco consumption. 3. To study the pattern of socioeconomic distribution of tobacco consumption among adolescents. METHODOLOGY A cross-sectional study carried out among 510 adolescents in the age group of 10-19 years of randomly selected villages of Narayanganj Block of Mandla Dist. of M.P., from May 2015 to September 2015 using a pre-designed pre-tested questionnaire. RESULT Overall prevalence of tobacco consumption in any form was found to be 27.25% in our study area; 33.33% male and 20.9% female adolescents were consuming tobacco products in any form and this difference was found to be statistically significant (χ2=9.3439, p=0.0022, OR=1.89; 98.56% adolescents consumed smokeless form of tobacco, while only 1.43% had the habit of smoking tobacco in the form of beedi/cigarettes among the tobacco users. Prevalence of tobacco use was significantly very high in late adolescents (38.95% as compared to the early adolescent period (16.09% (χ2=32.45; p=0.00, OR 3.32. Prevalence of consumption of tobacco in any form among adolescents who were earning was found to be 38.21%, while among the subjects who were either not earning, unemployed or students was 23.77%, which was statistically highly significant.

In spite of the high prevalence of malocclusion in adolescents reported worldwide, there are few studies that have investigated the association between normative malocclusion and self-rated dental and gingival appearance among adolescents. The aim of this study was to identify the association between normative malocclusion and dissatisfaction with dental and gingival appearance among Brazilian adolescents. A cross-sectional study was carried out with adolescents aged 15 to 19 years (n= 16,126) living in 250 towns of all five Brazilian regions. Dissatisfaction with dental and gingival appearance was the outcome. The main explanatory variable was malocclusion assessed by using the Dental Aesthetic Index - DAI. The other explanatory variables included were per capita family income, schooling delay, study conditions, sex, age, skin color, dental outcomes (untreated dental caries, missing teeth due dental caries, dental calculus, fluorosis, and dental pain) and use of dental services. Simple and multivariable Poisson regression analyses were performed. Dissatisfaction with dental appearance reached 11.4% (95%CI: 10.4-12.5) of the entire sample. All levels of malocclusion were associated with dissatisfaction with dental appearance. Adjusted multivariable analysis showed that dissatisfaction with dental appearance among individuals affected by severe or very severe malocclusion was respectively 40% and 80% higher than among those with normal occlusion. Malocclusion was associated with dissatisfaction with dental and gingival appearance. The results contribute to include self-rated dental appearance criteria in orthodontic treatment decision, mainly within the National Health System - SUS.

Full Text Available Abstract Background Despite extensive investigation of the neural systems for face perception and emotion recognition in adults and young children in the past, the precise temporal activation of brain sources specific to the processing of emotional facial expressions in older children and adolescents is not well known. This preliminary study aims to trace the spatiotemporal dynamics of facial emotion processing during adolescence and provide a basis for future developmental studies and comparisons with patient populations that have social-emotional deficits such as autism. Methods We presented pictures showing happy, angry, fearful, or neutral facial expressions to healthy adolescents (aged 10–16 years and recorded 128-channel event-related potentials (ERPs while they performed an emotion discrimination task. ERP components were analyzed for effects of age and emotion on amplitude and latency. The underlying cortical sources of scalp ERP activity were modeled as multiple equivalent current dipoles using Brain Electrical Source Analysis (BESA. Results Initial global/holistic processing of faces (P1 took place in the visual association cortex (lingual gyrus around 120 ms post-stimulus. Next, structural encoding of facial features (N170 occurred between 160–200 ms in the inferior temporal/fusiform region, and perhaps early emotion processing (Vertex Positive Potential or VPP in the amygdala and orbitofrontal cortex. Finally, cognitive analysis of facial expressions (P2 in the prefrontal cortex and emotional reactions in somatosensory areas were observed from about 230 ms onwards. The temporal sequence of cortical source activation in response to facial emotion processing was occipital, prefrontal, fusiform, parietal for young adolescents and occipital, limbic, inferior temporal, and prefrontal for older adolescents. Conclusion This is a first report of high-density ERP dipole source analysis in healthy adolescents which traces the sequence of

Religious group identification is an important but understudied social identity. The present study investigates religious group identification among adolescents of different faiths (Hindu, Muslim, Christian) living in multicultural Mauritius. It further explores how religious and national group identities come together among religious majority and minority adolescents. For three age groups (11 to 19 years, N = 2152) we examined the strength of adolescents' religious and national group identification, the associations between these two identities, and the relationships to global self-esteem. Across age and religious group, participants reported stronger identification with their religious group than with the nation. Identification with both categories declined with age, with the exception of Muslims, whose strong religious identification was found across adolescence. The association between religious and national identification was positive, albeit stronger for the majority group of Hindus and for early adolescents. We examined the manner in which religious and national identities come together using a direct self-identification measure and by combining the separate continuous measures of identification. Four distinct clusters of identification (predominant religious identifiers, dual identifiers, neutrals, and separate individuals) that were differently associated with global self-esteem were found. Dual identifiers reported the highest level of global self-esteem. The clusters of identification did not fully correspond to the findings for the direct self-identification measure. The results are discussed in terms of the meaning of dual identity and the positive manner in which adolescents can manage their multiple identities while taking into account the ideological framework in which those identities are played out.
Full Text Available Abstract Background Evidence on the differential impacts of the global food crisis as it translates into chronic food insecurity locally is essential to design food security interventions targeting the most vulnerable population groups. There are no studies on the extent of chronic food insecurity or its predictors among adolescents in developing countries. In the context of increased food prices in Ethiopia, we hypothesized that adolescents in low income urban households are more likely to suffer from chronic food insecurity than those in the rural areas who may have direct access to agricultural products. Methods This report is based on data from the first two rounds of the Jimma Longitudinal Family Survey of Youth (JLFSY. Both adolescents and households were selected using a stratified random sampling method. A total of 1911 adolescents aged 13-17 years were interviewed on their personal experiences of food insecurity both at baseline and at year two. Multivariable logistic regression analyses were used to compare chronic adolescent food insecurity by household income, household food insecurity, and socio-demographic variables after one year of follow-up. Results Overall, 20.5% of adolescents were food insecure in the first round survey, while the proportion of adolescents with food insecurity increased to 48.4% one year later. During the one year follow up period, more than half (54.8% of the youth encountered transient food insecurity – that is, either during the first or the second round survey. During the follow up period, 14.0% of adolescents had chronic food insecurity (i.e. were food insecure at both rounds. Multivariable logistic regression analysis showed that adolescents in the urban households with low (OR = 1.69, P = 0.008 and middle (OR = 1.80, P = 0.003 income tertiles were nearly twice as likely to suffer from chronic food insecurity compared with those in high income tertile, while this was not the case in

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

Eligible participants will be all student girls in grade 6 and 7, their parents and teachers in Isfahan governmental schools. This multi component school-based intervention include adolescents’ nutrition education package, parents’ nutrition massages, participatory homework, parents and teachers nutrition education package, supportive group, and collaboration with decision makers. Changing in nutrition behaviors including breakfast, fruit and vegetable, snack and fast food consumption will be examined, as primary outcome. Secondary outcome will be behavioral mediators such as knowledge, self-efficacy, intention, situation, self-regulation, social support, outcome expectations and expectancies, in adolescent girls. The outcomes will be assessed at baseline, and after 3 and 6-month follow-up.DiscussionThis study evaluates a school-based, guided SCT intervention, designed to improve healthy dietary behaviors, nutrition knowledge of adolescent girls. Few behavioral interventions have targeted this high-risk population in Iran. The intervention seems to be promising and has the potential to bridge the gap of the limited program outcomes of nutrition education in Iranian adolescents.

A longitudinal study was designed to examine the relation between Loevinger's measure of ego development and moral development as indexed by Rest's Defining Issues Test in a sample of 123 adolescents at 12 to 14 years of age and four years later. Study I assessed differential rates of change and theoretically predicted directions of change in the two developmental functions and gender differences in ego development. Substantial ego stage movement occurred (60 per cent advancement, 40 per cent stability); moral growth was moderate. Girls scored a half ego stage ahead of boys; patterns of directional change were similar. Ego level and moral development related at either fixed point in time, but ego functioning in early adolescence did not predict subsequent moral development. Study II addressed adolescents' perceptions of parenting styles in relation to these social cognitive functions. Parental behaviours that involve loving or support related to higher ego levels; parental demanding associated with lower ego development in early adolescence. Traditional gender-related parent socialization was found among girls and boys with greater ego development. The mediating role of perceived childrearing styles was considered in relation to gender differences in ego development.

Full Text Available Background: The main purpose of this study was to assess the factorial validity and reliability of the Iranian versions of the personality and behavior system scales (49 items of the AHDQ (The Adolescent Health and Development Questionnaire and interrelations among them based on Jessor′s PBT (Problem Behavior Theory. Methods: A multi-staged approach was employed. The cross-cultural adaptation was performed according to the internationally recommended methodology, using the following guidelines: translation, back-translation, revision by a committee, and pretest. After modifying and identifying of the best items, a cross-sectional study was conducted to assess the psychometric properties of Persian version using calibration and validation samples of adolescents. Also 113 of them completed it again two weeks later for stability. Results: The findings of the exploratory factor analysis suggested that the 7-factor solution with low self concept, emotional distress, general delinquency, cigarette, hookah, alcohol, and hard drugs use provided a better fitting model. The a range for these identified factors was 0.69 to 0.94, the ICC range was 0.73 to 0.93, and there was a significant difference in mean scores for these instruments in compare between the male normative and detention adolescents. The first and second-order measurement models testing found good model fit for the 7-factor model. Conclusions: Factor analyses provided support of existence internalizing and externalizing problem behavior syndrome. With those qualifications, this model can be applied for studies among Persian adolescents.

This multiple case study of ten families of normal private preparatory school adolescents and five families of substance abusing/mood disordered adolescents was an effort to identify factors that may suggest a relationship between the abuse of substances in adolescents who also have mood disorders and the following family factors: parental marital discord, degree of family satisfaction, and family problem-solving styles. The fifteen families completed four assessment instruments and participated in a videotaped problem-solving exercise. The results of this study showed that all members of the substance abusing/mood disordered adolescents' families rated themselves as dysfunctional in all major areas of family life. In contrast, the normal private preparatory school families reported satisfaction with most areas of family functioning. Communication styles also differed considerably between the two small groups of families. These results appear to support the importance of family evaluation and treatment when addressing the issue of adolescent substance abusers with mood disorders.

Full Text Available Abstract Background Information on mental health sequel in adolescents following natural disasters from developing countries is scant. Method Around one year after a super-cyclone, proportion of adolescents exhibiting post-traumatic psychiatric symptoms, prevalence of post-traumatic stress disorder (PTSD, major depression and generalized anxiety disorder, comorbidity and impairment of performance in school were studied in Orissa, India. Mini International Neuropsychiatric Interview for children and adolescents was used for evaluation and diagnosis. The criteria for diagnoses were based on Diagnostic and Statistical Manual of Mental Disorders – IV. Results Post-disaster psychiatric presentation in adolescents was a conglomeration of PTSD, depression and anxiety symptoms. The prevalences of PTSD, major depressive disorder and generalised anxiety disorder were 26.9%, 17.6% and 12.0% respectively. Proportion of adolescents with any diagnosis was 37.9%. Comorbidity was found in 39.0% of adolescents with a psychiatric diagnosis. Adolescents from middle socioeconomic status were more affected. There were gender differences in the presentation of the symptoms rather than on the prevalence of diagnoses. Prolonged periods of helplessness and lack of adequate post-disaster psychological support were perceived as probable influencing factors, as well as the severity of the disaster. Conclusion The findings of the study highlight the continuing need for identification and intervention for post-disaster psychiatric morbidities in adolescent victims in developing countries.

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

Full Text Available Introduction: Some studies demonstrated that dehydration process is prevalent among young populations and subsequently, a cause of concern. However, the evaluation of the fluid consumption pattern of children and adolescent populations has not been widely assessed. Objective: To evaluate the total fluid intake from different types of beverages in Spanish children and adolescents. Methods: A total of 238 children and adolescents aged 3-17 years were randomly recruited from all Spanish regions. The information about the quantity and quality of daily fluid intake from different types of beverages was collected using a 24 h fluid-specific diary over 7 consecutive days. Results: Fluid intake was < 80% of the EFSA recommendations in 87% of the study population. In our sample, water was the main contributor to fluid intake, followed by milk and derivates and sweet regular beverages. No differences in consumption patterns were found according to gender. Consumption of hot beverages as well as sweet regular and sweet light beverages increased with age, while milk and milk derivates consumption decreased. Conclusion: The large majority of our young population did not meet the EFSA recommendations for total water intake. Therefore, an increase in plain water consumption in children and adolescents should be promoted in order to fulfill the fluid needs without increasing calorie intake.

Full Text Available Adolescent obesity has tripled in the past two decades, and adolescents with disabilities, specifically autism spectrum disorders (ASD, may be at greater risk for obesity due to the behavioral, physical, and psychosocial complications related to their disorder. This case study reports the effects of video game playing on an obese adolescent with ASD and illustrates the use of a multiple baseline single subject design. Over 12 weeks, the participant played inactive (6 weeks and active video games (6 weeks on the Wii console. Physiological data were evaluated weekly at home. Stress and anxiety were measured via the Stress Survey Schedule for Individuals with Autism and Other Pervasive Non-Developmental Disorders (SSS and the Behavior Assessment System for Children Second Edition (BASC-2 pre- and postintervention. The Therapy Attitude Inventory (TAI was used to determine parental perception of video game playing as a socially valid intervention to reduce stress and anxiety. Results demonstrated that active video game playing slowed and/or reduced weight and BMI with minimal changes to waist-to-hip ratios, triceps skinfolds, and stress and anxiety. This study demonstrates how alternative methods for physical activity may be used to improve health outcomes of overweight/obese adolescents with ASD and suggests directions for future research.

Full Text Available Objective: To determine the prevalence of low back pain nonspecific and associated factors in schoolchildren. Method: This cross-sectional study investigated 343 adolescents, aged between 12 and 15 years, of both sexes of public schools. The questionnaire included questions regarding sociodemographic characteristics, type of school transportation, body mass index and low back pain. The outcome was defined as discomfort localized below the costal margin and above the inferior gluteal folds in the last 12 months. Results : The prevalence of low back pain in the last year was 57% (n=195 among participants, with no significant difference between the sexes (OR 1.13, 95% CI 0.93 to 1.37. Advancing age and body mass index were associated with the presence of low back pain in the bivariate analysis. The remaining seated at school in usual days was considered one of the main activities that trigger symptoms that lasted up to seven days for the majority (80% of adolescents. Conclusions: The high prevalence of low back pain presented, indicating that it is a common condition among these adolescents. There was no difference between the sexes, but had influence of age and body mass index. Our results point to the need for the development epidemiological studies of low back pain among children and adolescents.

The aim of this study was to determine the extent to which the linguistic forms used by adolescents in electronic mail (e-mail) differ from those used in standard written language. The study was conducted in French, a language with a deep orthography that has strict, addressee-dependent rules for using second person personal pronouns (unfamiliar and familiar forms). Data were collected from 80 adolescents ages 12 to 15 in a natural situation where they had to introduce themselves by e-mail to two addressees (peer/teacher). Participants were divided into two groups (skilled/unskilled in computer-mediated communication). Their emails contained a large number of orthographic deviations (the most frequent being neographic forms). Participants skilled in computer-mediated communication (CMC) deviated more than unskilled ones did. The number of orthographic deviations was not linked to the participants' standard writing ability. The personal-pronoun data clearly showed that adolescents used the familiar form of 'you' (tu) to address the peer and the unfamiliar form (vous) to address the teacher. We conclude that, for adolescents, e-mail constitutes a distinct written-language register. Nevertheless, the e-mail register seems to follow the pragmatic rules of standard spoken and written interaction.

Autoimmune thyroid diseases (AITD) are known to be clustered in families, but to what extent this occurs in childhood and adolescence is not well defined. In order to establish the prevalence of AITD in the siblings of affected children and adolescents, we examined 73 siblings from 66 families selected on the basis of a pediatric index patient. Sixty-six families, including a total of 146 offspring, were selected on the basis of diagnosis of chronic lymphocytic thyroiditis (CLT) (n = 55) or Graves' disease (GD) (n = 11). Among the 73 siblings examined, 20 new cases of CLT (27%) were detected. L-Thyroxine therapy was required in 4/20. History of AITD was recorded in 24/66 mothers (36%), and in two fathers. Overall in these families, considering both the index patients and the new patients, 86/141 (61%) children and adolescents were affected with AITD, with a female/male ratio of 3.3:1. Our study confirms that AITD clusters in families with a high prevalence in the siblings of affected children and adolescents. These children should be followed in order to avoid undiagnosed hypothyroidism. Prospective studies are warranted to identify predictive factors for overt thyroid disease.

Little is known about the epidemiology of pharmacotherapy in the treatment of child psychiatric disorder. This study reports on the systematic prospective collection of instances of new prescribing by child and adolescent mental health services serving a population of approximately four million people in North West England. Diagnostic and demographic information regarding new prescribing by child and adolescent mental health services within Greater Manchester and Lancashire was systematically collected prospectively over two 6-month periods between 2000 and 2002. Within the 12 months studied, there were 845 instances of a drug being newly prescribed to a child or adolescent in the treatment of a psychiatric disorder. In total, 48 different drugs were prescribed for 25 different diagnoses. The eight most commonly prescribed drugs were methylphenidate, methylphenidate/placebo trial, paroxetine, fluoxetine, risperidone, imipramine, dexamphetamine and melatonin, accounting for 73% of all prescribing. There was marked variation between services in the amount of prescribing with significant correlation between prescription of stimulants and prescription of selective serotonin reuptake inhibitor antidepressants. Prescription of medications in the treatment of child psychiatric disorder has become a significant part of child and adolescent mental health practice. However, the evidence base underpinning this usage remains limited, and further high quality therapeutic clinical trials are urgently needed.

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

Non-suicidal self-injury (NSSI) is highly prevalent in adolescence and has been suggested as an autonomous diagnosis in the Diagnostic and Statistical Manual (DSM-5). Social rejection is as potential risk-factor for NSSI and depression in adolescence. Objectives of this study were to identify differences in neural processing of social rejection in depressed adolescents with and without co-morbid NSSI and healthy controls. Participants were 28 depressed adolescents (14 with co-morbid NSSI, 79% females) and 15 healthy controls, with an average age of 15.2 years (SD=1.8). Social exclusion was implemented using the Cyberball paradigm 'Cyberball' during functional magnetic resonance imaging (fMRI). All participants reported feelings of social exclusion after fMRI scanning. Investigating the effects of NSSI, we found that depressed adolescents with NSSI showed relatively enhanced activation of the medial prefrontal cortex (mPFC) and the ventrolateral prefrontal cortex (vlPFC) compared to depressed adolescents without NSSI and also compared to healthy controls. Results point towards divergent processing of social exclusion in depressed adolescents with NSSI as compared to adolescents with mere depression in brain regions previously related to the processing of social exclusion. This finding of distinct neurophysiological responses may stimulate further research on individual treatment approaches.

This study investigated the determinants of overweight/obesity in adolescents. A cross-sectional survey was carried out on 1157 adolescents. Weight and height were measured. Information on socio-economic status (SES), dietary intakes, physical activity, and sedentary behaviours were collected by a self-administered questionnaire. Binary and multivariate binary logistic regressions were used to obtain the relationships and odds-ratios, respectively. The prevalence of overweight and obesity was higher among adolescents in low- or high-income families, adolescents whose mothers worked out of home, adolescents whose parents were both overweight, adolescents who watched a lot of TV or had excessive energy intake, adolescents with lower physical activity or lower intake of dietary fibre, those who skipped breakfast ≥ 4 times per week, and those with low and high fat intake. However, multiple logistic regression analysis showed that only energy intake was associated with increased odds and vegetables and fibre intake were associated with a reduction in the odds of being overweight (all poverweight/obesity than low and high SES due to better dietary intakes and less sedentary behaviours. Therefore, in overweight/obesity prevention programs, adolescents with determined risk factors from families with low and high SES should receive attention.

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.
Full Text Available The displacement hypothesis predicts that physical activity and media use compete in adolescents; however, findings are inconsistent. A more differentiated approach at determining the co-occurrence of physical activity and media use behaviors within subjects may be warranted. The aim of this study was to determine the co-occurrence of physical activity and media use by identifying clusters of adolescents with specific behavior patterns including physical activity in various settings (school, sports club, leisure time and different types of media use (watching TV, playing console games, using PC / Internet.Cross-sectional data of 2,083 adolescents (11-17 years from all over Germany were collected between 2009 and 2012 in the Motorik-Modul Study. Physical activity and media use were self-reported. Cluster analyses (Ward's method and K-means analysis were used to identify behavior patterns of boys and girls separately.Eight clusters were identified for boys and seven for girls. The clusters demonstrated that a high proportion of boys (33% as well as girls (42% show low engagement in both physical activity and media use, irrespective of setting or type of media. Other adolescents are engaged in both behaviors, but either physical activity (35% of boys, 27% of girls or media use (31% of boys and girls predominates. These adolescents belong to different clusters, whereat in most clusters either one specific setting of physical activity or a specific combination of different types of media predominates.The results of this study support to some extent the hypothesis that media use and physical activity compete: Very high media use occurred with low physical activity behavior, but very high activity levels co-occurred with considerable amounts of time using any media. There was no evidence that type of used media was related to physical activity levels, neither setting of physical activity was related to amount of media use in any pattern.

Full Text Available Abstract Background The Loozit® Study is a randomised controlled trial investigating extended support in a 24 month community-based weight management program for overweight to moderately obese, but otherwise healthy, 13 to 16 year olds. Methods This pre-post study examines the two month outcomes of the initial Loozit® group intervention received by both study arms. Adolescents (n = 151; 48% male and their parents separately attended seven weekly group sessions focused on lifestyle modification. At baseline and two months, adolescents' anthropometry, blood pressure, and fasted blood sample were assessed. Primary outcomes were two month changes in body mass index (BMI z-score and waist-to-height-ratio (WHtR. Secondary outcomes included changes in metabolic profile, self-reported dietary intake/patterns, physical and sedentary activities, psychological characteristics and social status. Changes in outcome measures were assessed using paired samples t-tests for continuous variables or McNemar's test for dichotomous categorical variables. Results Of the 151 adolescents who enrolled, 130 (86% completed the two month program. Among these 130 adolescents (47% male, there was a statistically significant (P 2 [0.41, 0.13], BMI z-score (0.05 [0.06, 0.03], WHtR (0.02 [0.03, 0.01], total cholesterol (0.14 mmol/L [0.24, 0.05] and low-density lipoprotein cholesterol (0.12 mmol/L [0.21, 0.04]. There were improvements in all psychological measures, the majority of the dietary intake measures, and some physical activities (P Conclusions The Loozit® program may be a promising option for stabilizing overweight and improving various metabolic factors, psychological functioning and lifestyle behaviors in overweight adolescents in a community setting.

Full Text Available Abstract Background Energy from liquids is one of the most important factors that could impact on the high prevalence of children and adolescents obesity around the world. There are few data on the liquid consumption in Brazil. The aim of this study is to evaluate the volume and quality of liquids consumed by Brazilian children and adolescents and to determine the proportion of their daily energy intake composed of liquids. Methods A multicenter study was conducted in five Brazilian cities; the study included 831 participants between 3 and 17 years of age. A four-day dietary record specific to fluids was completed for each individual, and the volume of and Kcal from liquid intake were evaluated. The average number of Kcal in each beverage was determined based on label information, and the daily energy intake data from liquids were compared with the recommendations of the National Health Surveillance Agency (Agência Nacional de Vigilância Sanitária– ANVISA, the Brazilian food regulation authority, according to each subject’s age. Results As the children aged, the volume of carbonated beverages that they consumed increased significantly, and their milk intake decreased significantly. For children between the ages of 3 and 10, milk and dairy products contributed the greatest daily number of Kcal from liquids. Sugar sweetened beverages which included carbonated beverages, nectars and artificial beverages, accounted for 37% and 45% of the total Kcal from liquid intake in the 3- to 6-year-old and 7- to 10- year-old groups, respectively. Among adolescents (participants 11- to 17- years old, most of the energy intake from liquids came from carbonated beverages, which accounted for an average of 207 kcal/day in this group (42% of their total energy intake from liquids. Health professionals should be attentive to the excessive consumption of sugar sweetened beverages in children and adolescents. The movement toward healthier dietary patterns at the
Full Text Available Abstract Background As epidemiological surveys have shown, binge drinking is a constant and wide-spread problem behavior in adolescents. It is not rare to find that more than half of all adolescents engage in this behavior when assessing only the last 4 weeks of time independent of the urbanity of the region they live in. There have been several reviews on predictors of substance consumption in adolescents in general, but there has been less high quality research on predictors of binge drinking, and most studies have not been theoretically based. The current study aimed to analyze the ultimate and distal factors predicting substance consumption according to Petraitis' theory of triadic influence. We assessed the predictive value of these factors with respect to binge drinking in German adolescents, including the identification of influence direction. Methods In the years 2007/2008, a representative written survey of N = 44,610 students in the 9th grade of different school types in Germany was carried out (net sample. The return rate of questionnaires was 88% regarding all students whose teachers or school directors had agreed to participate in the study. In this survey, prevalence of binge drinking was investigated as well as potential predictors from the social/interpersonal, the attitudinal/environmental, and the intrapersonal fields (3 factors of Petraitis. In a multivariate logistic regression analysis, these variables were included after testing for multicollinearity in order to assess their ability to predict binge drinking. Results Prevalence of binge drinking in the last 30 days was 52.3% for the surveyed adolescents with a higher prevalence for boys (56.9% than for girls (47.5%. The two most influential factors found to protect against binge drinking with p p Conclusions Whereas some of the risk and protective factors for binge drinking are not surprising since they are known for substance abuse in general, there are two points that
Full Text Available Background: Menstruation is an important milestone that results in development of sexual and reproductive capacity of girls. Adolescent girls do not have adequate knowledge about the abnormalities and healthy practices to be followed during menstruation. Objective:To find out the knowledge, attitude, practices regarding menstruation and treatment seeking behaviour for menstrual problems in adolescent females.Material & methods: The present cross sectional study was carried out in an urban field practice area of Department of Community Medicine, LLRM Medical College, Meerut on adolescent girls. A sample of 384 was derived and girls were selected by systematic random sampling technique. Detailed information was collected on a predesigned and pretested questionnaire. Results:38.5% girls were aware of menstruation prior to its onset out of which 66.9% learned from their mother. Only 14.6% of the menstruating girls were aware of at least one menstrual disorder. Dysmenorrhoea was found to be the most frequently occurring problem (58.4%, followed by oligomenorrhoea (16.2%, menorrhagia (13.9%, premenstrual tension (13.6%, infrequent menstruation (12.3% and polymenorrhoea (12.2%. Out of the 226(72.7% girls having menstrual problems 77.9% did not seek any treatment for their problems. 55.2% of the menstruating girls were using sanitary pads during menstruation. Conclusion: The adolescent girls are not well prepared and do not have adequate information regarding menstruation which is an important event of life.

Weight gain has been associated with behaviors related to diet, sedentary lifestyle, and physical activity. We investigated dietary patterns and possible meaningful clustering of physical activity, sedentary behavior, and sleep time in Spanish children and adolescents and whether the identified clusters could be associated with overweight. Analysis was based on a subsample (n = 415) of the cross-sectional ANIBES study in Spain. We performed exploratory factor analysis and subsequent cluster analysis of dietary patterns, physical activity, sedentary behaviors, and sleep time. Logistic regression analysis was used to explore the association between the cluster solutions and overweight. Factor analysis identified four dietary patterns, one reflecting a profile closer to the traditional Mediterranean diet. Dietary patterns, physical activity behaviors, sedentary behaviors and sleep time on weekdays in Spanish children and adolescents clustered into two different groups. A low physical activity-poorer diet lifestyle pattern, which included a higher proportion of girls, and a high physical activity, low sedentary behavior, longer sleep duration, healthier diet lifestyle pattern. Although increased risk of being overweight was not significant, the Prevalence Ratios (PRs) for the low physical activity-poorer diet lifestyle pattern were >1 in children and in adolescents. The healthier lifestyle pattern included lower proportions of children and adolescents from low socioeconomic status backgrounds. PMID:26729155

There is a considerable body of literature demonstrating that adolescence is a unique age period, which includes rapid and dramatic maturation of behavioral, cognitive, hormonal and neurobiological systems. Most notably, adolescence is also a period of unique responsiveness to alcohol effects, with both hyposensitivity and hypersensitivity observed to the various effects of alcohol. Multiple neurotransmitter systems are undergoing fine-tuning during this critical period of brain development, including those that contribute to the rewarding effects of drugs of abuse. The role of developmental maturation of the γ-amino-butyric acid (GABA) system, however, has received less attention in contributing to age-specific alcohol sensitivities. This review integrates GABA findings from human magnetic resonance spectroscopy studies as they may translate to understanding adolescent-specific responsiveness to alcohol effects. Better understanding of the vulnerability of the GABA system both during adolescent development, and in psychiatric conditions that include alcohol dependence, could point to a putative mechanism, boosting brain GABA, that may have increased effectiveness for treating alcohol use disorders.

Alarming reports have been published about hearing loss in adolescents, and increasing leisure time noise exposure has been blamed. If the exposure limits from the Noise at Work Regulations are applied, discotheque music as well as music from portable music players are associated with the risk of hearing loss. The empirical evidence for this association, however, is not sufficient. Not even an increase in the prevalence of noise-induced hearing loss among adolescents can be documented. OHRKAN is a prospective cohort study aimed to produce information on the prevalence of hearing loss as well as its risk factors in adolescents. Currently, a total of 2,240 pupils in grade 9 at schools in the city of Regensburg, Germany, have been recruited. Data on noise exposure were collected using standardized questionnaires. In addition, hearing status was assessed by medical examination including tympanometry, audiometry, and distortion-product otoacoustic emissions. Developments in noise exposure as well as hearing status will be assessed in follow-up data collections. Independent of this empirical assessment preventive measures are already needed now to reduce the risk of hearing loss in adolescents and young adults.

Full Text Available This study sought to conduct a comparatively analysis and describe the contents of the structure of the social representations of adolescents on quality of life. It involves descriptive, quantitative research, with the benchmark of a structural approach to social representations. The informants included 316 adolescents from three public schools in Jequié in the State of Bahia. The Spontaneous Word-Choice Eliciting Technique using the key expression "Quality of Life" was used for data collection. The responses were processed using Evoc 2003 software, which generated the Four-House Chart. The results reveal the core nucleus of the terms: healthy eating; physical activity; money; and sex. In the 1st outer circle, the words absence of disease, condoms, liberty, marijuana, housing, work and living well are featured. In the 2nd outer circle, there appeared the words difficulty, family, peace and power, and the contrasting elements of well-being and soccer. The overall consensus is that adolescents associate quality of life with sports and other healthy behavior activities, and are influenced by the desires and curiosities of adolescence.

This qualitative study explores community resilience factors within an indigenous Sámi community in Northern Norway. Semistructured interviews were conducted with 22 informants, 12 females and 10 males, ranging in age from 13 to 19 years old, 12 of whom had reindeer husbandry affiliation. Data analysis used a modified grounded theory approach and narrative analysis. Interpretation of the data was based on ecological perspectives theory and the identification of possible community resilience factors including Sámi language competence, use of recreational and natural resources, and traditional ecological knowledge, such as reindeer husbandry related activities. These cultural factors appear to strengthen adolescents' ethnic identity and pride, which in turn act as potential resilience mechanisms. Land was a significant arena for traditional practices and recreation. The majority of the youth reported support from relationships with extended godparents (fáddarat) and extended family (sohka) networks. The fáttar network was particularly strong among adolescents with reindeer husbandry affiliations. Native language competence and reindeer husbandry were key components in adolescent social networks. Interconnectedness among the community members and with the environment seemed to promote resilience and well-being. Two factors that excluded adolescents from full community membership and participation were being a nonnative Sámi language speaker and the absence of extended Sámi family networks.
Full Text Available Weight gain has been associated with behaviors related to diet, sedentary lifestyle, and physical activity. We investigated dietary patterns and possible meaningful clustering of physical activity, sedentary behavior, and sleep time in Spanish children and adolescents and whether the identified clusters could be associated with overweight. Analysis was based on a subsample (n = 415 of the cross-sectional ANIBES study in Spain. We performed exploratory factor analysis and subsequent cluster analysis of dietary patterns, physical activity, sedentary behaviors, and sleep time. Logistic regression analysis was used to explore the association between the cluster solutions and overweight. Factor analysis identified four dietary patterns, one reflecting a profile closer to the traditional Mediterranean diet. Dietary patterns, physical activity behaviors, sedentary behaviors and sleep time on weekdays in Spanish children and adolescents clustered into two different groups. A low physical activity-poorer diet lifestyle pattern, which included a higher proportion of girls, and a high physical activity, low sedentary behavior, longer sleep duration, healthier diet lifestyle pattern. Although increased risk of being overweight was not significant, the Prevalence Ratios (PRs for the low physical activity-poorer diet lifestyle pattern were >1 in children and in adolescents. The healthier lifestyle pattern included lower proportions of children and adolescents from low socioeconomic status backgrounds.
Full Text Available Background: Adolescents are often less informed, less experienced, and less comfortable accessing reproductive health information and services than adults. In many developing countries, a culture of silence surrounds the topic of menstruation and related issues; as a result many young girls lack appropriate and sufficient information regarding menstrual hygiene. This may result in incorrect and unhealthy behaviour during their menstrual period. Objectives: To assess and compare knowledge, belief, ideas, source of knowledge and practice of menstrual hygiene between school-going adolescents in an urban and a rural school of West Bengal, India. Methods: Cross-sectional, descriptive study was conducted among adolescent female students of Howrah district of West Bengal, India in the year 2011. Data was collected by pre-designed, pre-tested semi-structured self administered questionnaire. Results: The mean age at menarche was 12.1 years among urban and 12.2 years among the rural participants. More than 80% participants had some restrictions imposed during menstruation. Significantly higher number of urban girls had pre-menarchal knowledge on menstruation and used sanitary napkins. Conclusions: Menstrual hygiene is a vital aspect of health education for adolescent girls. For improvement of menstrual hygiene, sanitary napkins should be made universally available and affordable.

Evidence shows an association between muscular strength (MS) and health among young people, however low muscular strength cut points for the detection of high metabolic risk in Latin-American populations are scarce. The aim of this study was twofold: to explore potential age- and sex-specific thresholds of MS, for optimal cardiometabolic risk categorization among Colombian children and adolescents; and to investigate whether cardiometabolic risk differed by MS group by applying the receiver operating characteristic curve (ROC) cut point. MS was estimated by using a handle dynamometer on 1,950 children and adolescents from Colombia, using MS relative to weight (handgrip strength/body mass). A metabolic risk score was computed from the following components: waist circumference, triglycerides, HDL-c, glucose, and systolic and diastolic blood pressure. ROC analysis showed a significant discriminatory accuracy of MS in identifying the low/high metabolic risk in children and adolescents and in both genders. In children, the handgrip strength/body mass levels for a low metabolic risk were 0.359 and 0.376 in girls and boys, respectively. In adolescents, these points were 0.440 and 0.447 in girls and boys, respectively. In conclusion, the results suggest an MS level relative to weight for having a low metabolic risk, which could be used to identify youths at risk. PMID:28195167
Full Text Available : Adolescence is a time when the body prepares itself for the nutritional demands of pregnancy, lactation and heavy workloads that girls will soon experience. Good nutrition is essential for good health, physical growth and development, body composition and mental development In recent years, the incidence of adolescent pregnancy and childbirth is increasing due to the early onset of puberty, the declining age of menarche and early sexual activity. They need to earn to cope with the future demands of life. Nutritional needs during adolescence are increased because of the increased growth rate and changes in the body composition associated with puberty. The dramatic increase in energy and nutrient requirements coincides with other factors that may affect adolescents’ food choices and nutrient intake and thus nutritional status. National and population based surveys have found that adolescents often fail to meet dietary recommendations for over all nutritional status and for specific nutrient intakes. Nutritional requirements in relation to body size are more during adolescence. In a country like India with varying social customs and common beliefs against females there is a high prevalence of malnutrition amongst girls. Adolescents are tomorrow’s adult population and their health and well-being are crucial. Yet, interest in adolescents’ health is relatively recent and a focus on nutrition is even more recent. Nutrition influences growth and development throughout infancy, childhood and adolescence; it is, however, during the period of adolescence that nutrient needs are the greatest. A questionnaire-based study was undertaken in Jaipur city of Rajasthan with 500 respondents divided equally between government schools and private schools populations. Adolescent girl is subjected to more physical and mental challenges on a day –to-day basis due to ever increasing pressure of modernization. Hence they have to work hard physically as well as

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.

Using survey data from 325 Tsunami-exposed adolescents and mothers from two villages in southern Sri Lanka, this pilot study investigated influences of Tsunami exposure and subsequent psychosocial losses on adolescent depressive and post-traumatic stress disorder (PTSD) symptoms. Findings generally support the study hypotheses: disaster exposure (for example experiences of property destruction and deaths of close others) contributes to depressive and PTSD symptoms in adolescents. Findings also show that psychosocial losses associated with Tsunami exposure, such as prolonged displacement, social losses, family losses, and mental health impairment among mothers, contribute to depressive and PTSD symptoms in adolescents. Results suggest that the influence of Tsunami exposure on adolescent mental health operates partially through Tsunami-related psychosocial losses. As expected, positive mother-child relationships provide a compensatory influence on both depressive and PTSD symptoms of adolescents. In addition, high levels of depressive symptoms among mothers increases the detrimental influence of other Tsunami-related psychosocial losses on adolescent mental health. These preliminary findings suggest ways to improve ongoing recovery and reconstruction programs and assist in formulating new programs for families exposed to both the Tsunami and other natural disasters. More importantly, findings from this pilot study emphasize the urgent need for larger systematic studies focusing on mental health following disaster exposure.

Mercury (Hg) concentration in human hair is used to estimate methylmercury (MeHg) exposure and establish a reference dose for MeHg intake. In this study, Hg accumulation and MeHg intake were evaluated in relation to fish consumption habits in adolescents from two coastal areas: Angra do Heroísmo (Azores archipelago) and Murtosa (Portuguese mainland). Results showed that Hg concentration and MeHg intake increased with increasing fish consumption. In spite of that, Hg concentrations remained relatively low when compared with World Health Organization "no observed adversary effect level"; therefore, risk for mercury exposure should not be considered. Adolescents revealed a similar range of Hg concentrations (0.03-2.60 μg g(-1)) in scalp hair, apart from being exposed to natural or anthropogenic Hg source (Azores and Mainland, respectively). Nevertheless, Mainland volunteers generally exhibited higher values of Hg accumulation, being approximately 50 % of the results above 1 μg g(-1). Hg concentrations increased in both adolescent groups according to the weekly rate of fish meals, however, not linearly in the highest fish consumption rates. In fact, considering the adolescents' group having over one fish meal per week, the Hg bioaccumulation pattern found in the respective scalp hair suggests the ability of the human body to induce a self-protection response, probably mitigating Hg levels in the blood when experiencing increasing Hg exposure due to fish uptake. Actual and potential mercury levels in human scalp of adolescents probably diverge as fish consumption increases, the effective Hg uptake being lower than the expected, reducing risk to human health.

Objective Being overweight or obese is one of the most common reasons that children and adolescents are teased at school. We carried out a study in order to investigate: i) the relation between weight status and school bullying and ii) the relation between weight status categories and types of victimization and bullying in an outpatient sample of Italian children and adolescents with different degrees of overweight from minimal overweight up to severe obesity. Participants/Methods Nine-hundred-forty-seven outpatient children and adolescents (age range 6.0–14.0 years) were recruited in 14 hospitals distributed over the country of Italy. The participants were classified as normal-weight (N = 129), overweight (N = 126), moderately obese (N = 568), and severely obese (N = 124). The nature and extent of verbal, physical and relational bullying and victimization were assessed with an adapted version of the revised Olweus bully-victim questionnaire. Each participant was coded as bully, victim, bully-victim, or not involved. Results Normal-weight and overweight participants were less involved in bullying than obese participants; severely obese males were more involved in the double role of bully and victim. Severely obese children and adolescents suffered not only from verbal victimization but also from physical victimization and exclusion from group activities. Weight status categories were not directly related to bullying behaviour; however severely obese males perpetrated more bullying behaviour compared to severely obese females. Conclusions Obesity and bullying among children and adolescents are of ongoing concern worldwide and may be closely related. Common strategies of intervention are needed to cope with these two social health challenges. PMID:26606393

Video-gaming is an increasingly prevalent activity among children and adolescents that is known to influence several areas of emotional, cognitive and behavioural functioning. Currently there is insufficient experimental evidence about how extended video-game play may affect adolescents' sleep. The aim of this study was to investigate the short-term impact of adolescents' prolonged exposure to violent video-gaming on sleep. Seventeen male adolescents (mean age = 16 ± 1 years) with no current sleep difficulties played a novel, fast-paced, violent video-game (50 or 150 min) before their usual bedtime on two different testing nights in a sleep laboratory. Objective (polysomnography-measured sleep and heart rate) and subjective (single-night sleep diary) measures were obtained to assess the arousing effects of prolonged gaming. Compared with regular gaming, prolonged gaming produced decreases in objective sleep efficiency (by 7 ± 2%, falling below 85%) and total sleep time (by 27 ± 12 min) that was contributed by a near-moderate reduction in rapid eye movement sleep (Cohen's d = 0.48). Subjective sleep-onset latency significantly increased by 17 ± 8 min, and there was a moderate reduction in self-reported sleep quality after prolonged gaming (Cohen's d = 0.53). Heart rate did not differ significantly between video-gaming conditions during pre-sleep game-play or the sleep-onset phase. Results provide evidence that prolonged video-gaming may cause clinically significant disruption to adolescent sleep, even when sleep after video-gaming is initiated at normal bedtime. However, physiological arousal may not necessarily be the mechanism by which technology use affects sleep.

Binge eating (BE) is characterized by repeated, intermittent over-consumption of food in a brief period of time. This study aims to advance the understanding of potential risk factors for BE such as obesity, overeating and adolescence as an age group. We used the Otsuka Long Evans Tokushima Fatty (OLETF) rat, a genetic overeating-induced obesity model with increased preferences for sweet and fat. Adolescent and adult rats from both strains (OLETF and the lean control strain, Long Evans Tokushima Otsuka [LETO]) received limited access to a palatable liquid diet (Ensure vanilla) for three weeks. Water and chow were available throughout the study, but access to Ensure was limited to two hours, three times a week (3TW group) or every work day (5TW group). As expected, OLETF rats consumed more Ensure and were more BE-prone (BEP) than LETO rats at both ages. Adolescent rats showed a significantly larger binge size as demonstrated by a greater increase in Ensure intake, compared to adults. Furthermore, while the adults reduced their chow intake, compensating for increased Ensure intake, the adolescents increased their chow intake too. Finally, the adolescent rats showed binge like behavior earlier in the study and they tended to be BEP more than the adults. Our findings in rats suggest that adolescents and in particular obese adolescents are at risk for BE, and BE can lead to overweight, thus providing the basis for examination of biological mechanisms of this process in animal models.

Conscientiousness is associated with health, but the mechanisms remain poorly understood. To explore the role that stress might play, this study examined whether conscientiousness was associated with exposure and reactivity to life stress. This study followed 133 adolescent women every 6 months for 2.5 years. Participants completed a baseline measure of conscientiousness, and at each visit underwent a structured interview to catalogue episodic and chronic stress and had blood drawn to assess inflammatory processes. Participants higher in conscientiousness experienced fewer self-dependent episodic stressors and less academic and interpersonal chronic stress throughout the study. However, at times when they experienced higher levels of chronic interpersonal stress, they became more resistant to glucocorticoids. Higher levels of conscientiousness may protect adolescent women from exposure to certain stressors. However, when stress occurs, highly conscientious individuals may become more resistant to glucocorticoids, increasing their risk for processes that influence inflammatory conditions.

Full Text Available This paper presents an analysis of current approaches to the study of states of higher mental functions in children and adolescents suffering from various forms of hereditary myopathies. The aim of this work is to study the theoretical rationale and the possibility of specific disorders of mental function in children and adolescents with congenital myopathies. To achieve this objective during the study it was necessary to solve the following problems: give a description of the various groups and forms of congenital myopathies, their clinical characteristics; justify the possibility of considering the hereditary myopathies as a factor in the formation of changes in visual-spatial activities and thinking; evaluate the possibility to use complex neuropsychological psycho-diagnostic techniques for investigating the state of the higher mental functions of children with congenital myopathies. The possibility of neuropsychological correction for this category of patients is discussed also.

Although a high prevalence of substance use and its adverse effects on the course of the disease have been reported in adolescents with asthma, no studies have attempted to ameliorate the risk through adequate interventions. This pilot study evaluates and supports the feasibility and the effectiveness of a decision-making program in improving decision-making quality and reducing risk motivation over a 6-month study period. Differential effectiveness of the intervention was observed by race and gender. Although the improvement of decision-making quality was observed only in Whites, changes in risk motivation were detected only in non-Whites and girls. No significant reduction in actual substance use behavior was found. The intervention was favorably received by participants. An approach enhancing decision-making quality can be effective in addressing the risk of substance use in adolescent with asthma by altering motivations.

The aim of the present study was to assess the ability of 21 children and adolescents with Asperger syndrome (AS) of normal intelligence to infer mental states in a story context using Happe's Strange Stories test. The participants in the AS group were compared with an age-matched control group (N=20) of normally developing children and adolescents on a test of social understanding. The test material comprised social communication such as Pretence, Joke, Lie, White Lie, Figure of Speech, Misunderstanding, Persuasion, Irony, Double Bluff and Contrary Emotions, Appearance/Reality and Forgetting. As compared to the controls, the participants in the AS group performed less well on these tasks, and answered fewer correct mental state inferences, but performed well on a physical state control task. This study supports the main finding of earlier studies, showing that even individuals with AS of normal intelligence have problems in using mental state terms context-appropriately when tested on the Strange Stories test.

Full Text Available Background: Self – esteem is an important factor for helping persons deal with life stressors. It is an important determinant of psychological well-being that is particularly problematic during an adolescent life stage. Low self-esteem might contribute to depression through both interpersonal and intrapersonal pathways. Many theories of depression postulate that low self esteem is a defining feature of depression. Aims: Self-esteem in adolescents has been associated with a number of risk and protective factors in previous studies. This study examined the relationship between low self esteem and depression among adolescents. Methods: This study used a case control (retrospective design. Samples of 1120 adolescents, aged 14-17 years were selected for the study. Screening was done by using MINI-KID and the level of depression was assessed by using Beck depression inventory. Self esteem was measured by Rosenberg self esteem scale. Odds Ratio and Multivariate logistic regression were used to examine the relation between self-esteem and socio-demographic variables. Results: The odds ratio analysis revealed that adolescents who had low self esteem found to have 3.7 times (95% CI=1.9-6.9 and p- value 0.001 more risk of developing depression than the adolescents who had high self esteem. Conclusions: The findings implied that low self-esteem is a risk factor for depression among adolescents. Adolescents with low self esteem have to be identified earlier and prompt interventions will prevent future psychiatric illnesses. As an intervention towards the educational component pamphlet was distributed to the adolescents, parents and teachers. A concept programme called “Self Esteem Education & Development – SEED” programme, is planned for, from High school level.

The present study was conducted among 159 unmarried adolescents (80 non-athletes and 79 athletes) of age 15 to 19 years. The study participants belong to Bengali speaking Hindu ethnic group of Kolkata, the capital city of West Bengal State of India. Data were collected on socio-demographic and menstrual characteristics using pre-tested questionnaires. Anthropometric measurements were taken following standard methods. Descriptive statistics were used to understand the differences in menstrual characteristics between athletes and non-athletes, stepwise linear regression analyses were carried out to predict age at menarche, menstrual cycle length and duration of menstrual discharge using socio-demographic and anthropometric variables as well as athletic status as independent variables. Logistic (binary) regression was carried out to assess the strength of association between menstrual characteristics (as dependent variables) and athletic status, socio-demographic and anthropometric variables, and other menstrual characteristics (independent variables). The study participants differ significantly (p menstrual characteristics such as age at menarche, cycle length, skipped cycle, premenstrual syndrome, heavy discharge when compared for their athletic status. Certain anthropometric and socioeconomic variables were found to be significantly associated with their menstrual characteristics. The study results demonstrate that menstrual functioning among adolescents is significantly influenced by their athletic status. The findings of this study would help health care professionals to devise future health care programs for adolescents in gen- eral and athletes in particular.
Full Text Available Abstract Background Food insecurity not only affects physical growth and health of children but also their intellectual development, school attendance and academic performance. However, most evidences are based on studies in high income countries. Although food insecurity is common in Ethiopia, to what extent it affects school attendance and educational attainment of adolescents is not explored. We hypothesized that food insecure adolescents would be more likely to be absent from school and have lower grades attained after 1 year compared to their food secure peers. Methods We used data from 2009 adolescents in the age group of 13-17 years from two consecutive surveys of a five year longitudinal family study in Southwest Ethiopia. A stratified random sampling was used to select participants. Regression analyses were used to compare school absenteeism and the highest grade attained after 1 year of follow-up in food secure and insecure adolescents. The analysis was adjusted for demographic factors, reported illness and workload. Results Significantly more (33.0% food insecure adolescents were absent from school compared with their food secure peers (17.8%, P Conclusions Adolescent and household food insecurity are positively associated with school absenteeism and a lower educational attainment. Programs aiming to achieve universal access to primary education in food insecure environments should integrate interventions to ensure food security of adolescents.
Full Text Available Abstract Background Longitudinal epidemiological studies involving child/adolescent mental health problems are scarce in developing countries, particularly in regions characterized by adverse living conditions. We examined the influence of psychosocial factors on the trajectory of child/adolescent mental health problems (CAMHP over time. Methods A population-based sample of 6- to 13-year-olds with CAMHP was followed-up from 2002–2003 (Time 1/T1 to 2007–2008 (Time 2/T2, with 86 out of 124 eligible children/adolescents at T1 being reassessed at T2 (sample loss: 30.6%. Outcome: CAMHP at T2 according to the Child Behavior Checklist/CBCL’s total problem scale. Psychosocial factors: T1 variables (child/adolescent’s age, family socioeconomic status; trajectory of variables from T1 to T2 (child/adolescent exposure to severe physical punishment, mother exposure to severe physical marital violence, maternal anxiety/depression; and T2 variables (maternal education, child/adolescent’s social support and pro-social activities. Results Multivariate analysis identified two risk factors for child/adolescent MHP at T2: aggravation of child/adolescent physical punishment and aggravation of maternal anxiety/depression. Conclusions The current study shows the importance of considering child/adolescent physical punishment and maternal anxiety/depression in intervention models and mental health care policies.

Full Text Available BACKGROUND: Studies exploring the effect of television viewing on obesity throughout childhood are conflicting. Most studies have been confined to single high-income countries. Our aim was to examine the association between television viewing habits and Body Mass Index (BMI in adolescents and children in a multicentre worldwide sample. METHODS: In the International Study of Asthma and Allergies in Children Phase Three, adolescents aged between 12 and 15 years completed questionnaires which included questions on television viewing habits, height and weight. Parents/guardians of children aged between 5 and 8 years completed the same questionnaire on behalf of their children. The questionnaire asked "During a normal week, how many hours a day (24 hours do you (does your child watch television?" Responses were categorised as; "short" (5 hours. FINDINGS: 207,672 adolescents from 37 countries and 77,003 children from 18 countries provided data. Daily television viewing in excess of one hour was reported in 89% of adolescents and 79% of children. Compared with adolescents in the short viewing group, those in the moderate, long and prolonged groups had BMIs that were 0.14 kg/m(2, 0.21 kg/m(2, 0.30 kg/m(2 and 0.08 kg/m(2, 0.16 kg/m(2 and 0.17 kg/m(2 larger for females and males respectively (both P<0.001. Compared with children in the short viewing group, those in the moderate, long and prolonged groups had BMIs that were 0.24 kg/m(2, 0.34 kg/m(2, 0.36 kg/m(2 and 0.19 kg/m(2, 0.32 kg/m(2 and 0.36 kg/m(2 larger for females and males respectively (both P<0.001. INTERPRETATION: Increased television viewing hours were positively associated with BMI in both adolescents and children with an apparent dose response effect. These findings extend the evidence that television viewing contributes to increased BMI in childhood.

The substance use normalization thesis predicts that adolescent substance users are less likely to report substance use risk factors in high than in low prevalence countries. This study tests whether national population-level alcohol, cigarette and cannabis prevalence rates moderate the strength of the relationship between individual level social and behavioral risk factors and individual level alcohol, cigarette and cannabis use. Data from 2009/2010 Health Behaviour in School-Aged Children Study (N = 68,045, age = 15) from 35 countries was analyzed using logistic Hierarchical Linear Modeling. As expected based on low cannabis prevalence rates in all countries studied, no evidence of normalization was found for recent cannabis use. Also in line with the normalization thesis, results show that for substance use that reaches above 40% in at least some of the countries studied (drunkenness, alcohol and cigarette use), adolescents who reported use are less likely to report social and behavioral risk factors in high prevalence countries than in low prevalence countries. However, support for the normalization thesis was only partial in that results show that in models where evidence for normalization was found, there are risk factors that predict substance use to an equal degree regardless of country level prevalence rates. The current research shows that the normalization thesis is a useful framework for understanding the contextual aspects of adolescent alcohol, tobacco, and cannabis use. The study has implications for drug prevention as it suggests that selective prevention efforts may be particularly useful in low prevalence countries where screening based on risk factors may usefully identify adolescents at most risk for developing drug use problems. This approach may be less useful in high prevalence countries where screening based on risk factors is less likely to satisfactorily identify those at risk for developing drug use problems.

Full Text Available OBJECTIVES: A number of cross-sectional and prospective studies have now been published demonstrating inverse relationships between diet quality and the common mental disorders in adults. However, there are no existing prospective studies of this association in adolescents, the onset period of most disorders, limiting inferences regarding possible causal relationships. METHODS: In this study, 3040 Australian adolescents, aged 11-18 years at baseline, were measured in 2005-6 and 2007-8. Information on diet and mental health was collected by self-report and anthropometric data by trained researchers. RESULTS: There were cross-sectional, dose response relationships identified between measures of both healthy (positive and unhealthy (inverse diets and scores on the emotional subscale of the Pediatric Quality of Life Inventory (PedsQL, where higher scores mean better mental health, before and after adjustments for age, gender, socio-economic status, dieting behaviours, body mass index and physical activity. Higher healthy diet scores at baseline also predicted higher PedsQL scores at follow-up, while higher unhealthy diet scores at baseline predicted lower PedsQL scores at follow-up. Improvements in diet quality were mirrored by improvements in mental health over the follow-up period, while deteriorating diet quality was associated with poorer psychological functioning. Finally, results did not support the reverse causality hypothesis. CONCLUSION: This study highlights the importance of diet in adolescence and its potential role in modifying mental health over the life course. Given that the majority of common mental health problems first manifest in adolescence, intervention studies are now required to test the effectiveness of preventing the common mental disorders through dietary modification.

when compared with SC singletons, yet the differences were small and probably not of clinical relevance. WHAT IS KNOWN ALREADY: Previous studies have shown similar intelligence quotient (IQ) levels in ART and SC children, but only a few have been on adolescents. Academic performance measured...... with two SC control cohorts: a randomly selected singleton population (n = 5660) and all twins (n = 7064) born from 1995 to 1998 in Denmark. Nine children who died during the follow-up period were excluded from the study. PARTICIPANTS/MATERIALS, SETTING, METHODS: Mean test scores on a 7-point-marking scale...... singletons and ART twins. LIMITATIONS, REASONS FOR CAUTION: Missing data on educational test scores occurred in 6.6% of adolescents aged 15-16 years for the birth cohorts 1995-1997, where all of the children according to their age should have passed the ninth grade exam at the time of data retrieval...

OBJECTIVE: Smoking among people who have asthma may be a serious health problem. We studied the prevalence of smoking and the relations between smoking and asthma, symptoms, medicine, and gender differences among adolescents with asthma. METHODS: A national cross-sectional study on health...... adjusted for age, gender, parents' job and smoking, family type, body mass index, and exercise habits. RESULTS: In total, 37.7% smoked currently and 16.5% smoked daily; more girls than boys smoked. More pupils with asthma than without smoked daily (adjusted odds ratio [OR]: 1.15; 95% confidence interval...... with and without asthma were occasional smokers and ex-smokers at a similar prevalence. CONCLUSIONS: More pupils with asthma than without smoked daily, and they also smoked more cigarettes per day. This is a major health concern, as adolescents have a high smoking prevalence in Denmark.

Full Text Available ABSTRACT Objective To evaluate, in a community sample of adolescents, the presence of comorbidities in different anxiety disorders. Methods This is a cross-sectional study, initially composed of 2,457 adolescents, aged between 10-17 years old, from public schools of the area covered by the Basic Health Unit of a university hospital. We applied the Screen for Child Anxiety Related Emotional Disorders (SCARED to assess for anxiety disorders. Then, 138 positive cases in the screening were assessed for mental disorders through the Schedule for Affective Disorder and Schizophrenia for School-Age Children – Present and Lifetime Version (K-SADS-PL. Results Patients with anxiety disorders had more association with other anxiety disorders, as well as depression, and enuresis. The most common comorbidity described in our study was between generalized anxiety disorder and separation anxiety disorder (OR = 4.21, 95% CI 1.88, 9.58. Significant association was observed between other disorders such as enuresis and separation anxiety disorder (OR = 3.81, 95% CI 1.16, 12.49, as well as depression and generalized anxiety disorder (OR = 3.40; 95% CI 1.52, 7.61. Conclusion Our study showed a relevant presence of comorbidities adolescents with anxiety disorders, selected from a community sample, especially regarding other anxiety disorders. Nevertheless, further studies are needed to confirm our findings.

Full Text Available Abstract Introduction: Disorders of circadian rhythms have been reported in studies of both depressed children and of depressed adolescents. The aim of this study was to evaluate whether there is a relationship between the 24-hour spectral power (24h SP of the activity/rest rhythm and the clinical course of depression in adolescents. Methods: Six 14 to 17-year-old adolescents were recruited for the study. They were all suffering from major depressive disorder, according to the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV criteria, as identified by the Schedule for Affective Disorders and Schizophrenia for School Aged Children: Present and Lifetime Version (K-SADS-PL. Depressive symptoms were assessed using the Children's Depression Rating Scale - Revised (CDRS-R and clinical evaluations. Locomotor activity was monitored over a period of 13 consecutive weeks. Activity was measured for 10-minute periods using wrist-worn activity monitors. All patients were prescribed sertraline from after the first week up until the end of the study. Results: We found a relationship between high CDRS values and low 24-hour spectral power. Conclusions: The 24h SP of the activity/rest rhythm correlated significantly (negatively with the clinical ratings of depression.

Although environmental smoking (i.e., paternal and maternal smoking, sibling smoking, and peer smoking) is one of the most important factors for explaining adolescent smoking behavior, not all adolescents are similarly affected. The extent to which individuals are vulnerable to smoking in their environment might depend on genetic factors. The aim of this study was to examine the interplay between environmental smoking and genes encoding components of the dopaminergic system (i.e., dopamine receptor D2, D4, and dopamine transporter DAT1) in adolescent smoking onset. Data from two longitudinal studies were used. Study 1 consisted of 991 non-smoking early adolescents (mean age = 12.52, SD = .57) whereas study 2 consisted of 365 non-smoking middle to late adolescents (mean age = 14.16, SD = 1.07) who were followed for 16 and 48 months, respectively. Logistic regression analyses were conducted using Mplus. In study 1, we found positive associations between parents' and friends' smoking at the first measurement and smoking status 16 months later. In study 2 we found a positive association between friends' smoking and smoking onset 48 months later. Neither study demonstrated any interaction effects of the DRD2, DRD4, or DAT1 genotypes. In conclusion, the effects of environmental smoking on smoking onset are similar for adolescent carriers and non-carriers of these specific genes related to the dopaminergic system.

A steadily growing number of empirical research on cyberbullying exists retaining the traditional definition of bullying. However, whether this scientific and theoretical definition represents youths' perceptions and experiences with cyberbullying is a subject of further investigation. Scenarios of cyberbullying incidents were used and later discussed in three focus groups with 20 adolescents (55 % boys, 45 % girls, 11-16 years old). Thematic and content analyses laid focus on the following questions: (1) Which terms are used by the adolescents to describe the behaviors in the incidents? (2) What are the roles of traditional bullying definition criteria (i. e. intention, repetition, and power imbalance) and two additional cyberbullying-specific criteria (i. e. anonymity and publicity)? (3) How are the behaviors perceived in comparison to each other? Results show that German adolescents perceive "cybermobbing" as the best term to describe the presented incidents. Impersonation was not perceived as cyberbullying by the adolescents, but rather viewed as a criminal act. In addition, adolescents perceived the intent to harm, the impact on the victim, and repetition relevant for defining cyberbullying. Moreover, analyses revealed an interdependence between criteria which suggests that anonymity and publicity have an effect on the severity of the behavior, however they were not essential for the definition of cyberbullying.
The present study was aimed to find out the prevalence of overweight and obesity and its associated factors among Bengalee children and adolescents in the Kolkata, India. A total of 1061 Bengalee school children and adolescents (610 boys and 451 girls) participated and were divided into three age groups: Group I = 8-11 years; Group II = 12-15 years and Group III = 16-18 years. Overweight and obesity were defined as: Overweight (between ≥85 th and junk foodstuffs, breakfast skip, extra consumption of salt, and computer hours. Sedentary lifestyles, including increasing fast food preferences may be responsible for increasing occurrence of pediatric and adolescent obesity in this population.

Full Text Available The presence of gender violence is increasing alarmingly in our society and has become one of our most serious social problems. The data indicate that the origin of much of this type of behaviour has its roots in early adolescent relationships, in which the presence and repetition of chauvinist patterns and models has been verified. In this paper we assume that this kind of conduct is related to socially accepted behaviours that form part of the normative patterns typical of socialization processes. To analyse this thesis, an interdisciplinary group of researchers from Spanish and Chilean universities carried out a qualitative study on behaviours associated with gender violence in groups of adolescents and young people from different economic, geographic, social and ethnic contexts in order to gather evidence about the ways adolescents establish romantic or intimate relationships and to determine whether there are any indications of male chauvinist violence against adolescent women. The research design proposed takes as a reference the principles of Grounded Theory and employs the constant comparative method, that is, the information is collected, coded and analysed simultaneously, with theoretical sampling that involves selecting new cases as a function of their potential to help refine or expand the concepts and theories already developed. Thus, the coding of the discourse was carried out using open coding, axial coding and selective coding, and finally grouping the relevant categories or ideas into meta-categories to build the theoretical schema. Participating in the study were 156 adolescents (77 girls and 79 boys residing in the urban area of the Arica region in Chile, having been selected according to the variables “academic year” and “age”. Seventeen discussion groups were formed until data saturation was attained. The findings show that in these first adolescent dating relationships there is an important number of negative

Objective To determine the prevalence of vitamin D deficiency (<37.5 nmol/L) among young adolescents in Malaysia and its association with demographic characteristics, anthropometric measures and physical activity. Design This is a cross-sectional study among Form 1 (year 7) students from 15 schools selected using a stratified random sampling design. Information regarding sociodemographic characteristics, clinical data and environmental factors was collected and blood samples were taken for total vitamin D. Descriptive and multivariable logistic regression was performed on the data. Setting National secondary schools in Peninsular Malaysia. Participants 1361 students (mean age 12.9±0.3 years) (61.4% girls) completed the consent forms and participated in this study. Students with a chronic health condition and/or who could not understand the questionnaires due to lack of literacy were excluded. Main outcome measures Vitamin D status was determined through measurement of sera 25-hydroxyvitamin D (25(OH)D). Body mass index (BMI) was classified according to International Obesity Task Force (IOTF) criteria. Self-reported physical activity levels were assessed using the validated Malay version of the Physical Activity Questionnaire for Older Children (PAQ-C). Results Deficiency in vitamin D was seen in 78.9% of the participants. The deficiency was significantly higher in girls (92.6%, p<0.001), Indian adolescents (88.6%, p<0.001) and urban-living adolescents (88.8%, p<0.001). Females (OR=8.98; 95% CI 6.48 to 12.45), adolescents with wider waist circumference (OR=2.64; 95% CI 1.65 to 4.25) and in urban areas had higher risks (OR=3.57; 95% CI 2.54 to 5.02) of being vitamin D deficient. Conclusions The study shows a high prevalence of vitamin D deficiency among young adolescents. Main risk factors are gender, ethnicity, place of residence and obesity. PMID:27540095

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.

Full Text Available Background: Helicobacter pylori (H.pylori is a common bacterial infection, with considerably high morbidity and mortality worldwide. This bacterium represents a key factor in the etiology of various chronic infections ranging from gastritis, peptic ulcer disease to gastric cancer; but the prevalence has large variations in different communities. The aim of this study was to estimate the prevalence H. pylori infection in a nationally representative sample of Iranian adolescents.Materials and Methods: In this cross-sectional study, serum samples of 882 Iranian adolescents, aged 10-18 years, were examined for seroprevalence of H.pylori. They were randomly selected from the samples obtained in the third survey of a national surveillance program (the CASPIAN III study. Seroprevalence of H. pylori was examined by detection of H. pylori immunoglobulinA (IgA, immunoglobulinG (IgG and immunoglobulinM (IgM in sera by using Enzyme Linked Immunosorbant Assay (ELISA.Results: The study participants had a mean age of 14.82 + 2.77 years. Overall, 51.7% of students were boys and 61.52% were urban residents. The H. pylori IGM and IGA seropositivity had no significant association with demographic characteristics (p>0.05. The H. pylori IgG seropositivity were significantly different in boys and girls (69.7%, 95% confidence interval [CI] = 66.7-72.7 vs. 76.3%, 95%CI= 73.5-79. 1, respectively, P=0.03.Conclusion: The seroprevalence of H. pylori IgG in Iranian adolescents is high, and girls had greater risk of H. pylori IgG seropositivity compared to boys. Preventive strategies and health education are recommended to reduce the prevalence of this infection in Iranian adolescent.

This prospective study examined relations between preschool personality attributes and narcissism during adolescence and emerging adulthood. We created five a priori preschool scales anticipated to foretell future narcissism. Independent assessors evaluated the participants' personality at ages 14, 18, and 23. Based upon these evaluations, we generated observer-based narcissism scales for each of these three ages. All preschool scales predicted subsequent narcissism, except Interpersonal Anta...

Comparative research on parenting styles among Nordic and Mediterranean countries is still missing, despite the increasing number of studies on parenting styles in adolescence. This study explores similarities and differences in adolescents' retrospective perceptions of parenting styles, for both parents, in Sweden, Italy and Greece, using the Parenting Styles and Dimensions Questionnaire. In particular, it examines the relation between parental role, adolescent gender, country of origin, SES and these perceptions. Swedish, Italian and Greek adolescents (N = 702; 30.9% Swedish, 39.6% Italian and 29.5% Greek) participated in the study. To test the principal effects three mixed 2(parent; mother and father)*2(gender; girl and boy)*3(countries; Sweden, Italy and Greece)*3(SES; low, medium and high) ANOVAs were conducted separately for each parenting style. To verify the interaction effects, a mixed 2(parent; mother and father)*3(countries; Sweden, Italy and Greece)*3(SES; low, medium and high) ANOVA was tested on authoritative style. Regarding authoritarian and permissive two mixed 2(parent; mother and father)*2(gender; girl and boy)*3(countries; Sweden, Italy and Greece) ANOVAs were tested. Mothers, as compared to fathers, were perceived as more authoritative, authoritarian and permissive. Moreover, boys perceived their parents as more authoritarian and more permissive than girls. Swedish parents were perceived as significantly less authoritarian than Italian and Greek parents and more permissive than Italian parents; Greek parents were perceived as less authoritarian and more permissive than Italian parents. The study provides an interesting contribution to parenting styles literature, showing how country legislation concerning family matters and SES are related the perception of parenting behaviours.

Full Text Available Abstract Background There is increased recognition of the importance of breastfeeding at a national level as evidenced by the increased number of Canadian mothers initiating breastfeeding. However, adolescent mothers ( Methods The principles of interpretive description guided this qualitative study. A purposeful, homogenous sample of 16 adolescent mothers (15–19 years were recruited to complete individual, semi-structured, face-to-face interviews. Conventional content analysis was used to code data, identify concepts and synthesize them into overall themes. Results Adolescent mothers in this study expressed that the decision to breastfeed was made prenatally and while partner and family member opinions about breastfeeding initiation were influential, the decision was made independently. Mothers were primarily motivated to initiate breastfeeding due to the health benefits for the infant. Lower breastfeeding duration rates were found among mothers who decided to only “try” breastfeeding when compared to the mothers who committed to breastfeeding. Influences on continued breastfeeding included: 1 the impact of breastfeeding on social and intimate relationships; 2 the availability of social support; 3 the physical demands of breastfeeding; 4 mothers’ knowledge of breastfeeding practices and benefits; and 5 mothers’ perceived sense of comfort in breastfeeding. Conclusions The results of this study provide health care providers new conceptual insight and understanding of the factors that influence adolescents’ decisions to “try” breastfeeding and to continue providing breastmilk to their infants. Professional implications drawn from this study include active engagement of adolescents in the pre and postnatal periods, including early assessment of potential barriers surrounding breastfeeding decisions. This early professional interaction highlights the professional as a form of support, and allows for sharing of evidence

Rejection sensitivity (RS) has been defined as the tendency to readily perceive and overreact to interpersonal rejection. The primary aim of this study was to test key propositions of RS theory, namely that rejecting experiences in relationships with parents are antecedents of early adolescents' future RS and symptomatology. We also expanded this to consider autonomy-restrictive parenting, given the importance of autonomy in early adolescence. Participants were 601 early adolescents (age 9 to 13 years old, 51% boys) from three schools in Australia. Students completed questionnaires at school about parent and peer relationships, RS, loneliness, social anxiety, and depression at two times with a 14-month lag between assessments. Parents also reported on adolescents' difficulties at Time 1 (T1). It was anticipated that more experience of parental rejection, coercion, and psychological control would be associated with adolescents' escalating RS and symptoms over time, even after accounting for peer victimisation, and that RS would mediate associations between parenting and symptoms. Structural equation modelling supported these hypotheses. Parent coercion was associated with adolescents' increasing symptoms of social anxiety and RS over time, and parent psychological control was associated with increasing depressive symptoms over time. Indirect effects via RS were also found, with parent rejection and psychological control linked to higher T1 RS, which was then associated with increasing loneliness and RS. Lastly, in a separate model, peer victimisation and RS, but not parenting practices, were positively associated with concurrent parent reports of adolescents' difficulties.

Full Text Available Abstract Background Much attention has been paid to adolescents' screen time, however very few studies have examined non-screen sedentary time (NSST. This study aimed to (1 describe the magnitude and composition of screen sedentary time (SST and NSST in Australian adolescents, (2 describe the socio-demographic correlates of SST and NSST, and (3 determine whether screen time is an adequate surrogate for total sedentary behaviour in this population. Methods 2200 9-16 year old Australians provided detailed use of time data for four days. Non-screen sedentary time (NSST included time spent participating in activities expected to elicit Results Adolescents spent a mean (SD of 345 (105 minutes/day in NSST, which constituted 60% of total sedentary time. School activities contributed 42% of NSST, socialising 19%, self-care (mainly eating 16%, and passive transport 15%. Screen time and NSST showed opposite patterns in relation to key socio-demographic characteristics, including sex, age, weight status, household income, parental education and day type. Because screen time was negatively correlated with NSST (r = -0.58, and exhibited a moderate correlation (r = 0.53 with total sedentary time, screen time was only a moderately effective surrogate for total sedentary time. Conclusions To capture a complete picture of young people's sedentary time, studies should endeavour to measure both screen time and NSST.

The stress generation hypothesis was tested in two different longitudinal studies examining relations between weekly depression symptom ratings and stress levels in adolescents and emerging adults at varied risk for depression. The participants in Study 1 included 240 adolescents who differed with regard to their mothers' history of depressive disorders. Youth were assessed annually across 6 years (Grades 6-12). Consistent with the depression autonomy model, higher numbers of prior major depressive episodes (MDEs) were associated with weaker stress generation effects, such that higher levels of depressive symptoms predicted increases in levels of dependent stressors for adolescents with two or more prior MDEs, but depressive symptoms were not significantly related to dependent stress levels for youth with three or more prior MDEs. In Study 2, the participants were 32 remitted-depressed and 36 never-depressed young adults who completed a psychosocial stress task to determine cortisol reactivity and were reassessed for depression and stress approximately 8 months later. Stress generation effects were moderated by cortisol responses to a laboratory psychosocial stressor, such that individuals with higher cortisol responses exhibited a pattern consistent with the depression autonomy model, whereas individuals with lower cortisol responses showed a pattern more consistent with the depression sensitization model. Finally, comparing across the two samples, stress generation effects were weaker for older participants and for those with more prior MDEs. The complex, multifactorial relation between stress and depression is discussed.

Full Text Available The purpose of this study was to analyze risk factors for abortion among female teenagers from 12 to 19 years of age in the city of Maceió, Brazil. This is a cross-sectional study, conducted in ten schools. The sample was calculated by considering the number of admissions for postabortion curettage, obtained from the Information System of Hospitalization. Data were obtained through a semi-structured questionnaire divided into three basic blocks of data: sociodemographic, sexual life, and pregnancy/abortion. To analyze the data, the logistic regression model was used. The Forward Method was chosen to set the final model that minimizes the number of variables and maximizes the accuracy of the model. The significant analysis between the dichotomous variables provided eight significant variables. Two of them are protective for abortion: the ages 12-14 years and talking with parents about sex. After the logistic regression, the receipt of support for abortion was the most significant variable of all. The adolescent with an active sexual life, a previous pregnancy, who is married, and has received support for an abortion has a 99.74% probability for an abortion. The results of this study, demonstrating the importance of the group in adolescence, and the statistical significance of having a partner to support and approve the pregnancy appears as a preventive factor for abortion. It shows the importance of support and companionship for adolescent women.

Objective Research examining changes in eating disorder symptoms across adolescence suggests an increase in disordered eating from early to late adolescence. However, relevant studies have largely been cross-sectional in nature and most have not examined the changes in the attitudinal symptoms of eating disorders (e.g., weight concerns). This longitudinal study aimed to address gaps in the available data by examining the developmental trajectories of disordered eating in females from preadolescence into young adulthood. Method Participants were 745 same-sex female twins from the Minnesota Twin Family Study. Disordered eating was assessed using the Total Score, Body Dissatisfaction subscale, Weight Preoccupation subscale, and a combined Binge Eating and Compensatory Behavior subscale from the Minnesota Eating Behavior Survey assessed at the ages of 11, 14, 18, 21, and 25. Several latent growth models were fit to the data to identify the trajectory that most accurately captures the changes in disordered eating symptoms from 11 to 25 years. Results The best-fitting models for overall levels of disordered eating, body dissatisfaction, and weight preoccupation showed an increase in from 11 through 25 years. In contrast, bulimic behaviors increased to age of 18 and then stabilized to age of 25. Discussion The findings expanded upon extant research by investigating longitudinal, symptom specific, within-person changes and showing an increase in cognitive symptoms into young adulthood and the stability of disordered eating behaviors past late adolescence.

Full Text Available Abstract Objective The objective of this study was to compare intramuscular (IM ziprasidone to conventional IM medications (haloperidol combined with lorazepam for the treatment of severe agitation in adolescents (age 12–17. Methods We retrospectively identified consecutive severe agitation episodes (defined as requiring physical restraint in adolescents treated with either IM ziprasidone or conventional IM agents in a psychiatric emergency room. For ziprasidone, the dosage was 20 mg for 23 episodes and 10 mg for 5 episodes. For 24 episodes treated with combined haloperidol and lorazepam, the dosages were 4.8 ± 0.3 SEM mg and 1.9 ± 0.4 mg respectively. Outcomes were the duration of restraint and need for adjunctive "rescue" medications within 60 minutes. These outcomes were decided prior to reviewing any records. Results No difference was found in restraint duration (ziprasidone, N = 28, 55 ± 5 minutes; haloperidol with lorazepam N = 24, 65 ± 7 minutes, P = NS. Use of "rescue" medications did not differ between the two groups. No changes in blood pressure were found, but pulse decreased 8.3 ± 2.4 for haloperidol with lorazepam and 8.9 ± 4.24 for ziprasidone (P = NS. No instances of excessive sedation or extra-pyramidal symptoms were documented. Conclusion In this study, IM ziprasidone appeared effective, well tolerated, and similar in clinical profile to combined conventional IM medications for treating severe agitation in adolescents. Given the reportedly favorable acute side effect profile of parenteral atypical agents, they may provide an alternative to conventional antipsychotics for treating acute agitation in both adult and adolescent populations. Future randomized, controlled studies are needed.

This study explored the attitudes, beliefs, and behaviors of rural and farm adolescents regarding hearing conservation strategies. This qualitative study took place at two high schools in rural Michigan. Twenty-five adolescents living and working on farms or living in rural areas participated in one of two focus groups. Interviews were audio-recorded and transcribed verbatim. Transcripts were coded and analyzed by two researchers and checked by an additional researcher to ensure reliability. Noise exposure was ubiquitous among participants, both in farm-related (e.g., equipment, livestock) and non-farm-related (e.g., music, firearms) activities. Perceived barriers to use of hearing protection devices outweighed perceived benefits, resulting in uncommon use of protection. When hearing protection was used, it was usually earmuffs or earplugs. Participants indicated a lack of training in noise hazards and protective strategies. Despite their acknowledged risk of hearing loss, participants did not associate their use of hearing protection today with their hearing ability later in life. Categories emerging that relate to hearing protector use included: Barriers, benefits, self-efficacy, situational influences, impersonal influences, cues to action, susceptibility, and severity. Farm and rural adolescents are at risk for noise exposure and hearing loss. The findings stress the significance of work environment and adult modeling in facilitating hearing conservation behaviors. As indicated by the youths' recommendations, school-based interventions may be an effective approach to address this health concern. Intervention studies are needed to test various approaches that can effectively promote use of hearing conservation strategies among rural and farm adolescents.
This study examined victimisation, substance misuse, relationships, sexual activity, mental health difficulties and suicidal behaviour among adolescents with sexual orientation concerns in comparison to those without such concerns. 1112 Irish students (mean age 14 yrs) in 17 mixed-gender secondary schools completed a self-report questionnaire with standardised scales and measures of psychosocial difficulties. 58 students (5%) reported having concerns regarding their sexual orientation. Compared with their peers, they had higher levels of mental health difficulties and a markedly-increased prevalence of attempted suicide (29% vs. 2%), physical assault (40% vs. 8%), sexual assault (16%vs. 1%) and substance misuse. Almost all those (90%) with sexual orientation concerns reported having had sex compared to just 4% of their peers. These results highlight the significant difficulties associated with sexual orientation concerns in adolescents in Ireland. Early and targeted interventions are essential to address their needs.

Full Text Available This is an exploratory and descriptive study with the objective of analyzing the clinical and obstetric data related to the severe hypertensive disorders in adolescents assisted at a maternity school of Recife. The population was consisted of 186 pregnant adolescents with severe preeclampsia and/or eclampsia between 2003 and 2008. The age ranged between 15 and 19 years; they were black, single and had low education. Most of them were primiparas but the pregnancy recurrence was configured at 16% of cases. They did six or more prenatal consultations. The pregnancy progressed to term and the most frequent type of delivery was cesarean section. The comorbidities identified were changes in amniotic fluid volume, hemorrhages and infections. There were also identified cases of intrauterine growth retardation, prematurity, jaundice, hypoxia and low birth weight. It was concluded that teenage pregnancy associated with severe hypertensive syndrome is related to severe maternal, fetal and neonatal complications.
Full Text Available Common morbidity rate of adolescents aged from 15 to 18 years has been simultaneously estimated based on their appeals data to the polyclinics. These adolescents studied in public elementary schools and lyceums at medical high educational institutions of Tashkent city. Incidence was in 1.2-1.8 times higher among lyceum students than schoolchildren, while the structure of diseases was similar. The more important factors of morbidity in elementary schools and lyceums include iodine-deficiency, nonspecific respiratory diseases, iron-deficient anemia, gastritis, skin and subcutaneous tissue illnesses. These disease characteristics of in elementary schools and lyceums should be considered when organizing recreational activities, in particular, during improving physical education and optimization of learning environment.

Hierarchical linear modeling was used to examine the relationships between social capital (at the individual, the neighborhood, and the regional levels) and adolescents' fear of crime, while controlling for the main individual (sociodemographics, television viewing, and bullying victimization), neighborhood (neighborhood size and aggregated victimization), and regional (crime rate and level of urbanization) variables. Data were analyzed using a three-level model based on 22,639 15.7-year-old (SD = 0.67) students nested within 1081 neighborhoods and 19 Italian regions. The findings revealed that individual and contextual measures of social capital, modeled at the individual, neighborhood, and regional levels simultaneously, showed negative associations with adolescents' fear of crime. Males and participants with higher family affluence were less likely to feel fear of crime, whereas victimization, both at the individual and neighborhood levels, had a positive association with fear of crime. Strengths, limitations, and potential applications of the study are discussed.

Resilience, or the process of adjusting well to risk, relies on constructive collaboration between youths and their social ecologies. Although the literature details the risks of an intellectual disability (ID), there is little explanation of why some young people cope well despite these risks. Accordingly, we report a multiple case study that affords insight into the resilience of 24 adolescents with ID. Using a draw-and-talk methodology, these young people explained their resilience as enabled primarily by supportive social ecologies (which facilitated behavioral and emotional regulation, encouraged mastery, treated them as agentic beings, and offered safe spaces). Adolescents' positive orientation to their life-worlds co-facilitated their resilience. These insights advance effective ways to champion the resilience of young people with ID.

Although teachers and peers play an important role in shaping students' engagement, no previous study has directly investigated transactional associations of these classroom-based relationships in adolescence. This study investigated the transactional associations between adolescents' behavioral engagement, peer status (likeability and popularity), and (positive and negative) teacher-student relationships during secondary education. A large sample of adolescents was followed from Grade 7 to 11 (N = 1116; 49 % female; M age = 13.79 years). Multivariate autoregressive cross-lagged modeling revealed only unidirectional effects from teacher-student relationships and peer status on students' behavioral engagement. Positive teacher-student relationships were associated with more behavioral engagement over time, whereas negative teacher-student relationships, higher likeability and higher popularity were related to less behavioral engagement over time. We conclude that teachers and peers constitute different sources of influence, and play independent roles in adolescents' behavioral engagement.
Alcohol use disorders (defined as alcohol abuse or dependence) are prevalent and serious problems among adolescents and young adults. Adolescence is a time of trying new experiences and activities that emphasize socializing with peers, and conforming to peer-group standards. These new activities may place young people at particular risk for initiating and continuing alcohol consumption. Exposing the brain to alcohol during adolescence may interrupt key processes of brain development, leading to cognitive impairment as well as to further escalation of alcohol use. Alcohol-induced adolescent learning impairments could affect academic and occupational achievements. Functional magnetic resonance imaging (fMRI) is a relatively new imaging technique that allows studying neurocognitive function. fMRI aims to determine the neurobiological correlate of behavior by identifying the brain regions that become active during the performance of specific tasks in vivo. The technique is non-invasive and relatively safe. This allows repeated studies to be carried out within a given subject. Several fMRI studies have been performed to evaluate neurocognitive function in adolescents and young adults with alcohol use disorders. Adolescents and young adults with alcohol use disorders had abnormalities in brain response to a working memory task. The results of the studies of cue reactivity and craving responses in young people suggest that the elevated physiological response and altered cognitive reactions to alcohol are involved in the pathogenesis of alcohol dependence in adolescents and young adults. Future fMRI studies may help ascertain the adverse affects of alcohol on brain function during early neurodevelopmental stages. fMRI may be uniquely powerful in the delineation of the underlying pathophysiology of alcohol use disorders in adolescents and young adults.

This research investigated characteristics of natural mentoring relationships (mentor role, frequency of contact, closeness, duration) as predictors of adjustment outcomes among older adolescents and young adults (N = 2,053) in the Add Health study. Outcomes were assessed in the domains of education/work, problem behavior, psychological well-being, and physical health. Mentoring relationships with persons in roles outside of the family predicted greater likelihood of favorable outcomes in all domains except psychological well-being, relative to mentoring relationships with family members. Greater reported closeness in relationships was predictive of several favorable outcomes, particularly those in the domain of psychological well-being. These findings indicate that strategies to promote mentoring of adolescents may be more effective if particular categories of adults are targeted and an effort is made to cultivate relationships with strong emotional bonds. Editors' Strategic Implications: These data suggest that the cultivation of natural (especially non-familial) mentoring relationships during adolescence may be a promising strategy for prevention and health promotion. This study is impressive due to its large, nationally representative sample, the examination of relationship characteristics and multiple mentors, and the links to a variety of outcomes (controlling for earlier functioning). School officials and mentoring programs must consider how to capitalize on - and promote - naturally occurring mentor relationships.

Adolescence is a complex transitional period in human development, composing physical maturation, cognitive and social behavioral changes. The objective of this study is to investigate sex differences in white matter development and the associations between intelligence and white matter microstructure in the adolescent brain using diffusion tensor imaging (DTI) and tract-based spatial statistics (TBSS). In a cohort of 16 typically-developing adolescents aged 13 to 17 years, longitudinal DTI data were recorded from each subject at two time points that were one year apart. We used TBSS to analyze the diffusion indices including fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD), and radial diffusivity (RD). Our results suggest that boys (13-18 years) continued to demonstrate white matter maturation, whereas girls appeared to reach mature levels earlier. In addition, we identified significant positive correlations between FA and full-scale intelligence quotient (IQ) in the right inferior fronto-occipital fasciculus when both sexes were looked at together. Only girls showed significant positive correlations between FA and verbal IQ in the left cortico-spinal tract and superior longitudinal fasciculus. The preliminary evidence presented in this study supports that boys and girls have different developmental trajectories in white matter microstructure.
Full Text Available The perimenarcheal onset of polycystic ovarian syndrome (PCOS has long been recognized , through both its pathophysiology and the frequent onset of hirsutism and menstrual irregularities in this age group. How e ver , there is often a delay in diagnosing PCOS in adolescence because menstrual irregularity is frequently thought to be n ormal in the first 2 or 3 years after menarche, particularly if clinical signs of hyperandrogenism such as hirsutism or acne are mild or absent. This was a Cross - sectional Study consisting of 102 adolescent girls, aged 12 to 19 years, selected from patients attending the Gynecology Outpatient Clinic. In present study, level of insulin resistance along with markers of PCOS was assessed and compared in adolescent women with (cases or without (controls menstrual irregularities, a hall mark of PCOS. 18(35.29% cases versus 01(1.96% controls the Rotterdam criteria of PCOS.

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.

Whole grain consumption is associated with reduced risk of chronic disease. One-fifth of UK adults and children do not consume any whole grains, and adolescents have low consumption rates. Factors affecting whole grain intake among adolescents are not well understood. This study examined the socio-economic, environmental, lifestyle and psychological factors likely to influence consumption and explored whether outcomes aligned with behavioural predictors proposed in the Reasoned Action Approach. Five focus groups explored young people's attitudes towards, knowledge and consumption of wholegrain foods, as well as barriers to, and facilitators of, consumption. Participants were male and female adolescents (n = 50) aged 11-16 years from mixed socioeconomic backgrounds and ethnicities, recruited through schools in the city of Leeds, UK. Focus groups were analysed using thematic analysis. Most participants had tried wholegrain food products, with cereal products being the most popular. Many recognised whole grain health benefits related to digestive health but not those related to heart disease or cancers. Several barriers to eating whole grains were identified including: difficulties in identifying wholegrain products and their health benefits; taste and visual appeal; and poor availability outside the home. Suggested facilitators of consumption were advertisements and educational campaigns, followed by improved sensory appeal, increased availability and choice, and tailoring products for young people. All constructs of the Theory of Reasoned Action were identifiable in the data, suggesting that the factors influencing whole grain intake in adolescents are well captured by this model. Study outcomes may inform research and health promotion to increase whole grain intake in this age group.
Full Text Available Implicit self-esteem has remained an active research topic in both the areas of implicit social cognition and self-esteem in recent decades. The purpose of this study is to explore the development of implicit self-esteem in adolescents. A total of 599 adolescents from junior and senior high schools in East China participated in the study. They ranged in age from 11 to 18 years with a mean age of 14.10 (SD = 2.16. The degree of implicit self-esteem was assessed using the Implicit Association Test (IAT with the improved D score as the index. Participants also completed the Rosenberg Self-Esteem Scale (α = 0.77. For all surveyed ages, implicit self-esteem was positively biased, all ts>8.59, all ps<0.001. The simple correlation between implicit self-esteem and age was significant, r = -.25, p = 1. 10(-10. A regression with implicit self-esteem as the criterion variable, and age, gender, and age × gender interaction as predictors further revealed the significant negative linear relationship between age and implicit self-esteem, β = -0.19, t = -3.20, p = 0.001. However, explicit self-esteem manifested a reverse "U" shape throughout adolescence. Implicit self-esteem in adolescence manifests a declining trend with increasing age, suggesting that it is sensitive to developmental or age-related changes. This finding enriches our understanding of the development of implicit social cognition.

Objective: This study explores individual, home, and school/neighborhood environmental correlates of dietary behaviors (intake of fruits, vegetables, soft drinks, and unhealthy snacks among adolescents. Methods: In total, 742 adolescents with a mean age of 13.6 (SD=0.3 were included in this cross-sectional study conducted in 11 secondary schools located in the eastern part of Norway. A web-based questionnaire was used to collect data. Univariable and multivariable linear regression analyses were used to explore factors associated with the dietary behaviors included. Results: A higher frequency of food/drink purchase in the school canteen was related to a higher consumption of soft drinks and snacks. A higher frequency of food/drink purchase in shops around schools during break or recess was related to a higher consumption of snacks. A higher frequency of food/drink purchase in shops around the neighborhood on the way to and from school was related to a higher consumption of soft drinks. Perceived parental modeling and perceived accessibility at home were found to be positively associated with all dietary behaviors. Perceived parental rules were inversely associated with soft drink and snack consumption; self-efficacy related to healthy eating was positively associated with fruit and vegetable consumption. Other included school and neighborhood environmental correlates were not associated with the dietary behaviors. Conclusions: There is a need to address the food purchasing behavior of the adolescents using different approaches. The findings also highlight the important role of parents and the home environment for healthy and unhealthy dietary behaviors of adolescents.

Numerous research centres apply magnetic resonance imaging (MRI) for research purposes in children. In view of this practical research, ethical concerns regarding the strains the study participants are exposed to during the MRI examination are discussed. The study evaluates whether an MRI examination induces negative emotions in children and adolescents which are more intense than the ones caused by electroencephalography (EEG), an examination method currently classified as causing "minimal stress." Furthermore, the emotional stress induced by the MRI examination in children and adolescents is compared with that induced in adults. The study gathers data on examination-related emotions in children (age 8-17;11, male and female) who undergo an MRI examination of the cerebrum with a medical indication. The comparison group is a sample of children and adolescents examined with EEG (age 8-17;11, male and female) as well as a sample of adults (age 18-65, male and female) examined with MRI. At present, the study is in the stage of data collection. This article presents the study design of the MRI research project.

Children with cerebral palsy participate less in everyday activities than children in the general populations. During adolescence, rapid physical and psychological changes occur which may be more difficult for adolescents with impairments. Within the European SPARCLE project we measured frequency of participation of adolescents with cerebral palsy by administering the Questionnaire of Young People's Participation to 667 adolescents with cerebral palsy or their parents from nine European regions and to 4666 adolescents from the corresponding general populations. Domains and single items were analysed using respectively linear and logistic regression. Adolescents with cerebral palsy spent less time with friends and had less autonomy in their daily life than adolescents in the general populations. Adolescents with cerebral palsy participated much less in sport but played electronic games at least as often as adolescents in the general populations. Severity of motor and intellectual impairment had a significant impact on frequency of participation, the more severely impaired being more disadvantaged. Adolescents with an only slight impairment participated in some domains as often as adolescents in the general populations. Regional variation existed. For example adolescents with cerebral palsy in central Italy were most disadvantaged according to decisional autonomy, while adolescents with cerebral palsy in east Denmark and northern England played sports as often as their general populations. Participation is an important health outcome. Personal and environmental predictors of participation of adolescents with cerebral palsy need to be identified in order to design interventions directed to such predictors; and in order to inform the content of services.

The brain is a network and our intelligence depends in part on the efficiency of this network. The network of adolescents differs from that of adults suggesting developmental changes. However, whether the network changes over time at the individual level and, if so, how this relates to intelligence, is unresolved in adolescence. In addition, the influence of genetic factors in the developing network is not known. Therefore, in a longitudinal study of 162 healthy adolescent twins and their siblings (mean age at baseline 9.9 [range 9.0-15.0] years), we mapped local and global structural network efficiency of cerebral fiber pathways (weighted with mean FA and streamline count) and assessed intelligence over a three-year interval. We find that the efficiency of the brain's structural network is highly heritable (locally up to 74%). FA-based local and global efficiency increases during early adolescence. Streamline count based local efficiency both increases and decreases, and global efficiency reorganizes to a net decrease. Local FA-based efficiency was correlated to IQ. Moreover, increases in FA-based network efficiency (global and local) and decreases in streamline count based local efficiency are related to increases in intellectual functioning. Individual changes in intelligence and local FA-based efficiency appear to go hand in hand in frontal and temporal areas. More widespread local decreases in streamline count based efficiency (frontal cingulate and occipital) are correlated with increases in intelligence. We conclude that the teenage brain is a network in progress in which individual differences in maturation relate to level of intellectual functioning.

Full Text Available A pregnant adolescent’s vulnerability increases when she is a victim of intrafamilial violence and drug addiction, which cause physical and biopsychosocial damage to the mother and her baby. Objective Present and analyze the case of an adolescent who is addicted to drugs, pregnant and the victim of lifelong intrafamilial violence. Method A case study based on a semi-structured interview conducted in the Obstetrics Emergency Unit at the Teaching Hospital of the University of São Paulo. The data were interpreted and analyzed using Content Analysis. Results intrafamilial violence experienced at the beginning of the adolescent’s early relationships seriously affected her emotional maturity, triggering the development of psychopathologies and leaving her more susceptible to the use and abuse of alcohol and other drugs. The adolescent is repeating her history with her daughter, reproducing the cycle of violence. Conclusion Adolescent pregnancy combined with intrafamilial violence and drug addiction and multiplies the adolescent’s psychosocial vulnerability increased the adolescent’s vulnerability.
Language impairments are a well established finding in patients with schizophrenia and in individuals at-risk for psychosis. A growing body of research has revealed shared risk factors between individuals with psychotic-like experiences (PLEs) from the general population and patients with schizophrenia. In particular, adolescents with PLEs have been shown to be at an increased risk for later psychosis. However, to date there has been little information published on electrophysiological correlates of language comprehension in this at-risk group. A 64 channel EEG recorded electrical activity while 37 (16 At-Risk; 21 Controls) participants completed the British Picture Vocabulary Scale (BPVS-II) receptive vocabulary task. The P300 component was examined as a function of language comprehension. The at-risk group were impaired behaviourally on receptive language and were characterised by a reduction in P300 amplitude relative to the control group. The results of this study reveal electrophysiological evidence for receptive language deficits in adolescents with PLEs, suggesting that the earliest neurobiological changes underlying psychosis may be apparent in the adolescent period.
Full Text Available Abstract Adolescence’s changes may become more pronounced when living with a chronic condition (CC. This study aims to examined the differences in satisfaction with family life, perception of school competence and “pressure with homework” of Portuguese adolescents’ 1 living with CC; 2 how living with CC affects school participation; taking into account age, gender and family socioeconomic status (SES. Five thousand fifty Portuguese adolescents (mean age 14 ± 1.85 of the Health Behaviour in School-aged Children (HBSC/WHO were included. Results showed increased vulnerability in adolescents living with CC, presenting a lower satisfaction with family life and poor school outcomes. Younger boys, having a higher SES and not having CC are significantly associated with satisfaction with family life. Older girls, having a lower SES and living with CC were associated with more stress related to school work. Future interventions should include these features combined with ‘listening’ to adolescents and their needs, allowing their participation in the promotion of personal health.
Full Text Available Background: The aim of this study was to describe the trends of smoking and snuff consumption in adolescents in Nord-Trøndelag, Norway, in the period from 1995/97 to 2006/08, with special emphasize on regional and gender differences.Method: We used data from all three waves of the Young-HUNT study, the youth part (ages 13-19 yrs of the HUNT study, Nord- Trøndelag County, Norway. Young-HUNT 1 was conducted in 1995-97 (N=9131, 90% response rate, Young-HUNT 2 in 1999-2000 (N=2808, 80% response rate and Young-HUNT 3 in 2006-08 (N=8601.Results: Fewer adolescents had tried smoking in Young-HUNT 3 (40.6% compared to Young-HUNT 1 (56.5%, while the prevalence of adolescents who had tried snuff increased in the same period from 17.4% to 23.5%. The prevalence of adolescents who smoked daily or occasionally decreased between Young- HUNT 1 (girls 23.8%, boys 19.8% and Young-HUNT 3 (girls: 14.6%, boys: 12.1%, while the prevalence of daily or occasionally snuffing increased (girls: 3.4% to 13.0% and boys: 20.2% to 23.1%. This constitutes a fourfold increase of the number of young female snuff users in little more than a decade. Occasional snuff use increased most in girls while daily snuff use increased most in boys. The same tendency was seen inn all regions, but the prevalence of tobacco use varied.Conclusion: The results demonstrate a shift from cigarette smoking to snuff use in the adolescent population between 1995 and 2008. Although a decrease in cigarette smoking occurred, the increasing snuff use makes the total tobacco consumption nearly constant

The increasing prevalence of overweight in young people suggests that adolescent nutritional status is influenced by environmental factors. Using hierarchical modelling, this study aimed to analyse the association between individual, household and neighborhood factors and adolescent nutritional status and well-being. The study used data from a population-based household survey conducted in Belo Horizonte, the capital of the State of Minas Gerais, Brazil, between 2008 and 2009. Data was obtained from an adult and adolescent in each household using a confidential questionnaire and anthropometric measurements. Adolescent nutritional status was evaluated using multinomial regression analysis considering distal and proximal influences. The prevalence of overweight and thinness among the sample of 1,030 adolescents was 21.9% and 4.6%, respectively. Although variables from all blocks remained in the final model, head of household education level, family habits and family nutritional status were shown to strongly influence adolescent nutritional status. New approaches to public health are needed which focus on raising awareness and promoting health education targeting teenagers and their social context.

Purpose Despite its clinical importance, adolescent subthreshold depression remains a largely neglected topic. The aims of this study were to accurately identify the natural course of depressive symptoms and the risk for developing major depressive episode (MDE) in late adolescents with subthreshold depression over 1 year. Patients and methods One hundred and seventy-two participants <20 years of age (mean age: 18.32 years, standard deviation: 0.50), who did not meet the full criteria for an MDE, were selected from 2,494 screened freshmen based on the Beck Depression Inventory, 2nd edition (BDI-II). We conducted a cohort study of three groups (low-, middle-, and high-symptom groups) divided based on BDI-II scores, over a 1 year period with the use of bimonthly assessments. Temporal changes of depressive symptoms were analyzed using linear mixed modeling and growth mixture modeling. Results First, we found that late adolescents with subthreshold depression (high depressive symptoms) were split between the increasing and decreasing depressive symptoms groups, whereas the majority of the less-symptoms group remained stable during 1 year. Second, in comparison with late adolescents with less depressive symptoms, those with subthreshold depression had an elevated risk of later depression. Conclusion Some late adolescents with subthreshold depression had increased depressive symptoms and developed an MDE during 1 year. Therefore, it is necessary for us to rigorously assess the changes in subthreshold depressive symptoms over time in late adolescents. PMID:28053534

Full Text Available Abstract Background Association between psychiatric morbidity and substance abuse among adolescent has been reported. However prevalence and pattern of such dysfunctions are unknown in our environment. Aims To determine the prevalence of psychosocial dysfunction and depressive symptoms among adolescents who abuse substance and also note the influence of socio-demographic factors and type of substance on the pattern of dysfuction. Method A cross-sectional study was carried out among 900 adolescents selected from 29 secondary schools in Enugu metropolis. A multi-stage sampling procedure was used to select the students. The student drug use questionnaire was used to screen respondents for substance abuse. Those who were abusing substance and matched controls (non substance abusers were assessed for psychiatric symptoms using the 35-item Paediatric Symptom Checklist (PSC and the Zung Self-rating Depression Scale (SDS. Social classification was done using the parental educational attainment and occupation. Result A total of 290 students were current substance abusers. The substances most commonly abused were alcohol (31.6%, cola nitida (kola nut (20.7% and coffee (15.7%. Using the PSC scale, 70 (24.1% subjects compared to 29 (10.7% of the controls had scores in the morbidity range of ≥ 28 for psychosocial dysfuction. This was statistically significant (χ2 = 17.57 p = 0.001. Fifty-four subjects (18.6% had scores in the morbidity range of ≥ 50 for depressive symptoms using the Zung SDS compared to 21 (7.7% of controls. This was statistically significant (χ2 = 14.43, p = 0.001. Prevalence of dysfunction was not significantly related to age in both subjects and controls (χ2 = 4.62, p = 0.010, χ2 = 4.8, p = 0.10 respectively. Also using both scales, there was no significant relationship between psychosocial dysfunction and gender or social class in both subjects and control. The prevalence of dysfuction using both scales was significantly higher
