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

Drug overdose deaths in the United States are a pressing public health challenge (1–3). In particular, drug overdoses involving opioids have increased since 1999 (1). This report focuses specifically on drug overdose deaths for older adolescents aged 15–19. In 2015, 772 drug overdose deaths occurred in this age group. Rates for 1999–2015 are presented and trends compared for both females and males. Percent distributions of drug overdose deaths for 2015 by intent (e.g., unintentional, suicide, homicide) are presented. Trends in drug overdose death rates by type of drug involved are also presented.

To assess selected vaccination coverage among adolescents by health insurance status and other access-to-care characteristics. The 2015 National Immunization Survey-Teen data were used to assess vaccination coverage disparities among adolescents by health insurance status and other access-to-care variables. Multivariable logistic regression analysis and a predictive marginal modeling were conducted to evaluate associations between health insurance status and vaccination coverage. Overall, vaccination coverage was significantly lower among uninsured compared with insured adolescents for all vaccines assessed for except ≥3 doses of human papillomavirus vaccine (HPV) among male adolescents. Among adolescents 13-17 years of age, vaccination of uninsured compared with insured adolescents, respectively, for tetanus toxoid, reduced content diphtheria toxoid, and acellular pertussis vaccine was 77.4% vs 86.8%; for ≥1 dose of meningococcal conjugate vaccine was 72.9% vs 81.7%; for ≥1 dose of HPV was 38.8% vs 50.2% among male and 42.9% vs 63.8% among female adolescents; for 3 doses of HPV was 24.9% vs 42.8% among female adolescents. In addition, vaccination coverage differed by the following: type of insurance among insured adolescents, having a well-child visit at 11-12 years of age, and number of healthcare provider contacts in the past year. Uninsured were less likely than insured adolescents to be vaccinated for HPV (female: ≥1 dose and 3 doses; and male: ≥1 doses) after adjusting for confounding variables. Overall, vaccination coverage was lower among uninsured adolescents. HPV vaccination coverage was lower than tetanus toxoid, reduced content diphtheria toxoid, and acellular pertussis vaccine Tdap and meningococcal conjugate vaccine in both insured and uninsured adolescents. Wider implementation of effective evidence-based strategies is needed to help improve vaccination coverage among adolescents, particularly for those who are uninsured. Limitation of

Reliance on self-reported dietary intake methods is a commonly cited research limitation, and dietary misreporting is a particular problem in children and adolescents. Objective indicators of dietary intake, such as dietary biomarkers, are needed to overcome this research limitation. The added sugar (AS) biomarker δ13C, which measures the relative abundance of 13C to 12C, has demonstrated preliminary validity in adults. The purpose of this investigation was to determine the comparative validity, test-retest reliability, and sensitivity of the δ13C biomarker to detect AS and sugar-sweetened beverage (SSB) intake using fingerstick blood samples in children and adolescents. Children (aged 6-11 y, n = 126, 56% male, mean ± SD age: 9 ± 2 y) and adolescents (aged 12-18 y, n = 200, 44% male, mean ± SD age: 15 ± 2 y) completed 4 testing sessions within a 3-wk period. Participants' height, weight, demographic characteristics, and health history were determined at the first session; 24-h recalls were obtained at each visit and fingerstick blood samples were collected at visits 1 and 3. Samples were analyzed for δ13C value using natural abundance stable isotope mass spectrometry. δ13C value was compared with dietary outcomes in the full sample, and in child and adolescent subgroups. t Tests and correlational analyses were used to assess biomarker validity and reliability, whereas logistic regression and area under the receiver-operator characteristic curve (AUC) were used to evaluate sensitivity. Reported mean ± SD AS consumption was 82.2 ± 35.8 g/d and 329 ± 143 kcal/d, and SSB consumption was 222 ± 243 mL/d and 98 ± 103 kcal/d. Mean δ13C value was -19.65 ± 0.69‰, and was lower in children than in adolescents (-19.80 ± 0.67‰ compared with -19.56 ± 0.67‰, P = 0.002). δ13C values were similar across sessions (visit 1: -19.66 ± 0.68‰; visit 3: -19.64 ± 0.68‰; r = 0.99, P < 0.001) and were associated (P < 0.001) with intake of total AS (grams

This study aimed to develop the Scale for Quality of Life in Pediatric Oncology Patients Aged 13-18: Adolescent Form and Parent Form. We used the child and parent information form, Visual Quality of Life Scale, and our own scale, the Scale for Quality of Life in Pediatric Oncology Patients Aged 13-18: Adolescent Form and Parent Form. We finalized the 35-item scale to determine the items, received opinions from 14 specialists on the scale, and pilot-tested the scale in 25 children and their parents. We used Pearson correlation analysis, Cronbach α coefficient, factor analysis and receiver operating characteristics analysis to analyze the data. The total Cronbach α of the parent form was .97, the total factor load was .60-.97 and the total variance was 80.4%. The cutoff point of the parent form was 85.50. The total Cronbach α of the adolescent form was .98, the total factor load was .62-.96, and the total variance explained was 83.4%. The cutoff point of the adolescent form was 75.50. As a result of the parent form factor analysis, we determined the Kaiser-Meyer-Olkin coefficient as .83, the Barlett test χ(2) as 12,615.92; the factor coefficients of all items of the parent form ranged from .63 to .98. The factor coefficients of all items of the adolescent form ranged from .34 to .99. As a result of the adolescent form factor analysis, we determined the KMO as .79, and the Barlett test χ(2) as 13,970.62. Conclusively, we found that the adolescent form and the parent form were valid and reliable in assessing the children's quality of life. Copyright © 2016. Published by Elsevier B.V.

A retrospective analysis was conducted using data from the National Electronic Injury Surveillance System for children and adolescents 5-19 years of age treated in emergency departments for injuries associated with skateboards from 1990 through 2008. An estimated 1 226 868 children/adolescents (95 % CI: 948 733-1 505 003) were treated in emergency departments for skateboarding-related injuries from 1990 through 2008, an average of 64,572 cases per year. From 1990 through 1994, the annual rate of injuries per 10,000 children/adolescents significantly decreased overall and for males (overall: 72.9 %, P = 0.014; males: 73.9 %, P = 0.011; females: 63.6 %, P = 0.062).

Health and risk behaviours tend to be maintained from adolescence into adulthood. There is little knowledge on whether meal frequencies in adolescence are maintained into adulthood. We investigated whether breakfast, lunch and evening meal frequencies in early adolescence predicted meal frequencies in late adolescence and in early adulthood. Further, the modifying effect of gender and adolescent family structure were investigated. National representative sample of 15-year-olds in Denmark with 4 and 12 year follow-up studies with measurement of breakfast, lunch and evening meal frequencies. A total of 561 persons completed questionnaires at age 15 years (baseline 1990, n=847, response rate 84.6%), age 19 years (n=729, response rate 73.2%) and age 27 years (n=614, response rate 61.6%). Low meal frequencies at age 15 years was a significant predictor for having low meal frequencies at age 19 years (odds ratio (OR, 95% CI)) varying between 2.11, 1.33-3.34 and 7.48, 3.64-15.41). Also, low meal frequencies at age 19 years predicted low meal frequencies at age 27 years (OR varying between 2.26, 1.30-3.91 and 4.38, 2.36-8.13). Significant predictions over the full study period were seen for low breakfast frequency and low lunch frequency (OR varying between 1.78, 1.13-2.81 and 2.58, 1.31-5.07). Analyses stratified by gender showed the same patterns (OR varying between 1.88, 1.13-3.14 and 8.30, 2.85-24.16). However, the observed predictions were not statistical significant among men between age 15 and 27 years. Analyses stratified by adolescent family structure revealed different lunch predictions in strata. Having low meal frequencies in early adolescence predicted low meal frequencies in late adolescence and early adulthood. We propose that promotion of regular meals become a prioritised issue within health education.

To estimate prevalence and identify correlates of age of smoking initiation among adolescents in Africa. Data (n = 16,519) were obtained from nationally representative Global Youth Tobacco Surveys in nine West African countries. Study outcome was adolescents' age of smoking initiation categorized into six groups: ≤7, 8 or 9, 10 or 11, 12 or 13, 14 or 15 and never-smoker. Explanatory variables included sex, parental or peer smoking behavior, exposure to tobacco industry promotions, and knowledge about smoking harm. Weighted multinomial logit models were conducted to determine correlates associated with adolescents' age of smoking initiation. Age of smoking initiation was as early as ≤7 years; prevalence estimates ranged from 0.7 % in Ghana at 10 or 11 years age to 9.6 % in Cote d'Ivoire at 12 or 13 years age. Males, exposures to parental or peer smoking, and industry promotions were identified as significant correlates. West African policymakers should adopt a preventive approach consistent with the World Health Organization Framework Convention on Tobacco Control to prevent an adolescent from initiating smoking and developing into future regular smokers.

The 13-valent pneumococcal conjugate vaccine (PCV13) was first recommended for use in adults aged ⩾19years with immunocompromising conditions in June 2012. On August 2014, the Advisory Committee on Immunization Practices (ACIP) recommended routine use of PCV13 among adults aged ⩾65years. We assessed adverse events (AEs) reports following PCV13 in adults aged ⩾19years reported to the Vaccine Adverse Event Reporting System (VAERS) from June 2012 to December 2015. VAERS is a national spontaneous reporting system for monitoring AEs following vaccination. Our assessment included automated data analysis, clinical review of all serious reports and reports of special interest. We conducted empirical Bayesian data mining to assess for disproportionate reporting. VAERS received 2976 US PCV13 adult reports; 2103 (71%) of these reports were from PCV13 administered alone. Fourteen percent were in persons aged 19-64years and 86% were in persons aged ⩾65years. Injection site erythema (28%), injection site pain (24%) and fever (22%) were the most frequent AEs among persons aged 19-64years; injection site erythema (30%), erythema (20%) and injection site swelling (18%) were the most frequent among persons aged ⩾65years who were given the vaccine alone. The most frequently reported AEs among non-death serious reports were injection site reactions and general malaise among persons 19-64years old; injection site reactions, general malaise and Guillain-Barré syndrome among those ⩾65years (Table 2). Data mining did not detect disproportional reporting for any unexpected AE. The results of this study were consistent with safety data from pre-licensure studies of PCV13. We did not detect any new or unexpected AEs. Published by Elsevier Ltd.

A popular algorithm to predict VO2Peak from the one-mile run/walk test (1MRW) includes body mass index (BMI), which manifests practical issues in school settings. The purpose of this study was to develop an aerobic capacity model from 1MRW in adolescents independent of BMI. Cardiorespiratory endurance data were collected on 90 adolescents aged 13-16 years. The 1MRW was administered on an outside track and a laboratory VO2Peak test was conducted using a maximal treadmill protocol. Multiple linear regression was employed to develop the prediction model. Results yielded the following algorithm: VO2Peak = 7.34 × (1MRW speed in m s(-1)) + 0.23 × (age × sex) + 17.75. The New Model displayed a multiple correlation and prediction error of R = 0.81, standard error of the estimate = 4.78 ml kg(-1) · min(-1), with measured VO2Peak and good criterion-referenced (CR) agreement into FITNESSGRAM's Healthy Fitness Zone (Kappa = 0.62; percentage agreement = 84.4%; Φ = 0.62). The New Model was validated using k-fold cross-validation and showed homoscedastic residuals across the range of predicted scores. The omission of BMI did not compromise accuracy of the model. In conclusion, the New Model displayed good predictive accuracy and good CR agreement with measured VO2Peak in adolescents aged 13-16 years.

The aim of this study was to investigate whether there are differences in the amplitude of the EMG signal among five different age groups of adolescent's muscle. Fifteen healthy adolescents participated in this study and they were divided into five age groups (13, 14, 15, 16 and 17 years). Subjects were performed dynamic contraction during lifting a standard weight (3-kg dumbbell) and EMG signals were recorded from their Biceps Brachii (BB) muscle. Two common EMG analysis techniques namely root mean square (RMS) and mean absolute values (MAV) were used to find the differences. The statistical analysis was included: linear regression to examine the relationships between EMG amplitude and age, repeated measures ANOVA to assess differences among the variables, and finally Coefficient of Variation (CoV) for signal steadiness among the groups of subjects during contraction. The result from RMS and MAV analysis shows that the 17-years age groups exhibited higher activity (0.28 and 0.19 mV respectively) compare to other groups (13-Years: 0.26 and 0.17 mV, 14-years: 0.25 and 0.23 mV, 15-Years: 0.23 and 0.16 mV, 16-years: 0.23 and 0.16 mV respectively). Also, this study shows modest correlation between age and signal activities among all age group's muscle. The experiential results can play a pivotal role for developing EMG prosthetic hand controller, neuromuscular system, EMG based rehabilitation aid and movement biomechanics, which may help to separate age groups among the adolescents.

Purpose Osteoporosis is primarily evident in postmenopausal women, but its roots are traceable to periods of growth, including during adolescence. Depression, anxiety, and smoking are associated with lower bone mineral density (BMD) in adults. These associations have not been studied longitudinally across adolescence when more than 50% of bone accrual occurs. Methods To determine the impact of depressive and anxiety symptoms, smoking, and alcohol use on bone accrual in girls 11–19 years, 262 healthy girls were enrolled in age cohorts of 11, 13, 15, and 17 years. Using a cross-sequential design, girls were seen for 3 annual visits. Outcome measures included total body bone mineral content (TB BMC) and BMD of the total hip and lumbar spine using dual energy x-ray absorptiometry. Depressive and anxiety symptoms and smoking and alcohol use were by self-report. Results Higher-frequency smoking was associated with a lower rate of lumbar spine and total hip BMD accrual from age 11–19. Higher depressive symptoms were associated with lower lumbar spine BMD across all ages. There was no effect of depressive symptoms on TB BMC, and there was no effect of alcohol intake on any bone outcome. Conclusion Adolescent smokers are at higher risk for less than optimal bone accrual. Even in the absence of diagnosable depression, depressive symptoms may influence adolescent bone accrual. These findings have import for prevention of later osteoporosis and fractures. PMID:23298983

Primiparous women delivering a singleton at Bradford Royal Infirmary between March 2007 and December 2010 aged ≤19 years (n=640) or 20-34 years (n=3951). Subgroup analysis was performed using women aged ≤16 years (n=68). Women aged 20-34 years were used as the reference group. Maternal and neonatal outcomes. The odds of extremely low birth weight (<1000 g) were significantly higher in the adolescent group (≤19 years) compared with the reference group (adjusted OR (aOR) 4.13, 95% CI 1.41 to 12.11). The odds of very (<32 weeks) and extremely (<28 weeks) preterm delivery were also higher in the adolescent group (aOR 2.12, 95% CI 1.06 to 4.25 and aOR 5.06, 95% CI 1.23 to 20.78, respectively).Women in the adolescent group had lower odds of gestational diabetes (aOR 0.35, 95% CI 0.20 to 0.62), caesarean delivery (aOR 0.53, 95% CI 0.42 to 0.67 and instrumental delivery (aOR 0.53, 95% CI 0.41 to 0.67). This study identifies important differences in maternal and neonatal outcomes between women by age group. These findings could help in identifying at-risk groups for additional support and tailored interventions to minimise the risk of adverse outcomes for these vulnerable groups. Further work is needed to identify the causal mechanisms linking age with outcomes in adolescent women where significant gaps in the literature exist. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Globally, increasing numbers of HIV-infected children are reaching adolescence due to antiretroviral therapy (ART). We investigated rates of loss-to-follow-up (LTFU) from HIV care services among children as they transition from childhood through adolescence. Individuals aged 5-19 years initiated on ART in a public-sector HIV clinic in Bulawayo, Zimbabwe, between 2005 and 2009 were included in a retrospective cohort study. Participants were categorized into narrow age-bands namely: 5-9 (children), 10-14 (young adolescents) and 15-19 (older adolescents). The effect of age at ART initiation, current age (using a time-updated Lexis expansion) and transitioning from one age group to the next on LTFU was estimated using Poisson regression. Of 2273 participants, 1013, 875 and 385 initiated ART aged 5-9, 10-14 and 15-19 years, respectively. Unlike those starting ART as children, individuals starting ART as young adolescents had higher LTFU rates after moving to the older adolescent age-band (Adjusted rate ratio (ARR) 1.54; 95% CI: 0.94-2.55) and similarly, older adolescents had higher LTFU rates after transitioning to being young adults (ARR 1.79; 95% CI: 1.05-3.07). In older adolescents, the LTFU rate among those who started ART in that age-band was higher compared to the rate among those starting ART at a younger age (ARR = 1.70; 95% CI: 1.05, 2.77). This however did not hold true for other age-groups. Adolescents had higher rates of LTFU compared to other age-groups, with older adolescents at particularly high risk in all analyses. Age-updated analyses that examine movement across narrow age-bands are paramount in understanding how developmental heterogeneity in children affects HIV outcomes.

Abstract Introduction: Globally, increasing numbers of HIV-infected children are reaching adolescence due to antiretroviral therapy (ART). We investigated rates of loss-to-follow-up (LTFU) from HIV care services among children as they transition from childhood through adolescence. Methods: Individuals aged 5–19 years initiated on ART in a public-sector HIV clinic in Bulawayo, Zimbabwe, between 2005 and 2009 were included in a retrospective cohort study. Participants were categorized into narrow age-bands namely: 5–9 (children), 10–14 (young adolescents) and 15–19 (older adolescents). The effect of age at ART initiation, current age (using a time-updated Lexis expansion) and transitioning from one age group to the next on LTFU was estimated using Poisson regression. Results: Of 2273 participants, 1013, 875 and 385 initiated ART aged 5–9, 10–14 and 15–19 years, respectively. Unlike those starting ART as children, individuals starting ART as young adolescents had higher LTFU rates after moving to the older adolescent age-band (Adjusted rate ratio (ARR) 1.54; 95% CI: 0.94–2.55) and similarly, older adolescents had higher LTFU rates after transitioning to being young adults (ARR 1.79; 95% CI: 1.05–3.07). In older adolescents, the LTFU rate among those who started ART in that age-band was higher compared to the rate among those starting ART at a younger age (ARR = 1.70; 95% CI: 1.05, 2.77). This however did not hold true for other age-groups. Conclusions: Adolescents had higher rates of LTFU compared to other age-groups, with older adolescents at particularly high risk in all analyses. Age-updated analyses that examine movement across narrow age-bands are paramount in understanding how developmental heterogeneity in children affects HIV outcomes. PMID:28715158

Dental erosion is a pathological condition resulting from the irreversible dissolution of the mineralized portion of the teeth, being recognized in modern society as an important cause of loss of tooth structure. The aim of this study was to assess the prevalence and its association with diet in Brazilian adolescents of Campina Grande, PB, Brazil. A population-based study was conducted on a stratified sample of 675 adolescents aged from 15 to 19 of both sexes using the index proposed by O'Sullivan. Dental examinations were performed by two calibrated dentists (kappa = 0.82). The significance level adopted was 5%. The prevalence of dental erosion was 21%, and the upper central incisors and lateral incisors were the most affected elements, with 50.5% and 40.2%, respectively. The buccal surface showed greater impairment (51.4%) and 67.8% of teeth with dental erosion had more than half of the surface of affected area. Most damage was on the enamel (93.5%). There were no statistically significant differences between the occurrence of dental erosion and gender, age, socioeconomic status, self-reported ethnicity, and diet. There was high prevalence of dental erosion in its early stages among adolescents and there were no significant differences in the frequency of the consumption of foods and beverages and the presence of dental erosion.

The growth status of North Korean refugee children and adolescents from 6 to 19 years of age.

This paper is a study of the growth status of 1406 North Korean refugee children and adolescents who were between 6 and 19.9 years of age at the time of their arrival in South Korea, during the years 1995-2007, as compared with that of their South Korean peers. Refugee children of 6.5 years of age were found to be taller and heavier than North Korean children of the same age residing in North Korea. On the other hand, all of the North Korean refugee boys and girls were shorter and weighed less than their South Korean peers. This disparity in height and weight growth status was smallest during the pre-teen years and then began to increase, peaking in the mid-teen years and decreasing in the late-teen years, with the late-teen disparity being still larger than the pre-teen one. This pattern of disparity suggests that the greatest gap observed in mid-teen years was caused by differences in growth tempos during the period of pubertal growth and that the final differences in body size between the North and South Korean adults were partly pubertal in origin. The mean height-for-age z-score (HAZ) and weight-for-age z-score (WAZ) of the North Korean refugee boys were significantly lower than those of the North Korean refugee girls, indicating that the girls' growth status was better than that of the boys. In addition, the WAZ of the North Korean refugee children and adolescents was higher than their HAZ, indicating that their growth in height is poorer than that of weight. A regression analysis revealed that the mean HAZ of North Korean refugee children and adolescents born between 1995 and 1999, a period during which North Korea suffered a famine, was not statistically significantly lower than that of those born earlier. The time that the North Korean children and adolescents spent outside of North Korea before entering South Korea was discovered to have had a positive effect on their growth status, suggesting that they experienced some degree of catch-up growth while

Patients with cancer, particularly those with hematologic malignancies, are at an increased risk of invasive pneumococcal disease (IPD) and they are included in the list of subjects for whom pneumococcal vaccination is recommended. The main aim of this study was to evaluate Streptococcus pneumoniae colonization in school-aged children and adolescents with cancer to determine the potential protective efficacy of 13-valent pneumococcal conjugate vaccine (PCV13). An oropharyngeal swab was obtained from 277 patients (age range 6-17 years) with cancer during routine clinical visits and analyzed for S. pneumoniae using real-time polymerase chain reaction. S. pneumoniae was identified in 52 patients (18.8%), including 47/235 (20.0%) with hematologic malignancies and 5/42 (11.9%) with solid tumors. Colonization declined significantly with an increase in age (odds ratio [OR] 0.34, 95% confidence interval [CI] 0.16-0.71, and OR 0.30, 95% CI 0.11-0.82 in children aged 10-14 and ≥15 years, respectively, as compared to those <10 years). Carriage was more common among patients with leukemia or lymphoma than in children with solid tumors. Co-trimoxazole prophylaxis was significantly associated with reduced pneumococcal carriage (OR 0.41, 95% CI 0.19-0.89). A total of 15/58 (25.9%) and 26/216 (12.0%) children were colonized by PCV13 serotypes among cancer patients previously vaccinated and not vaccinated with 7-valent pneumococcal conjugate vaccine (PCV7), respectively. In conclusion, this study indicates that children and adolescents with cancer are frequently colonized by S. pneumoniae. Because most of the carried serotypes are included in PCV13, this vaccine is presently the best solution to reduce the risk of IPD in these patients.

Anxiety Disorders in Adolescents and Psychosocial Outcomes at Age 30

Essau, Cecilia A.; Lewinsohn, Peter M.; Olaya, Beatriz; Seeley, John R.

2014-01-01

Background Anxiety disorders are associated with adverse psychosocial functioning, and are predictive of a wide range of psychiatric disorders in adulthood. Objective The present study examined the associations between anxiety disorders during childhood and adolescence and psychosocial outcomes at age 30, and sought to address the extent to which psychopathology after age 19 mediated these relations. Method Eight hundred and sixteen participants from a large community sample were interviewed twice during adolescence, at age 24, and at age 30. They completed self-report measures of psychosocial functioning and semi-structured diagnostic interviews during adolescence and young adulthood. Results Childhood anxiety only predicted less years of completed education at age 30, whereas adolescent anxiety predicted income, unemployment, maladjustment, poor coping skills, more chronic stress and life events. Adult major depressive disorder (MDD) was the only disorder predicted by childhood anxiety, whereas adolescent anxiety predicted MDD, substance (SUD) and alcohol abuse/dependence (AUD) in adulthood. No adult psychopathology mediated the relationship between childhood anxiety disorders and psychosocial outcomes at age 30. Adult MDD, SUD and AUD partially or completely mediated the association between adolescent anxiety and most domains of psychosocial functioning at age 30. Limitations The participants are ethically and geographically homogenous, and changes in the diagnostic criteria and the interview schedules across the assessment periods. Conclusion Adolescent anxiety, compared to childhood anxiety, is associated with more adverse psychosocial outcomes at age 30. Adolescent anxiety affects negative outcomes at age 30 directly and through MDD, SUD and AUD. PMID:24456837

Sex-typed behavior was assessed at age 3 using the Pre-School Activities Inventory, and at age 13 using the Multidimensional Gender Identity Scale, in 54 masculine boys, 57 masculine girls, 75 feminine boys, 65 feminine girls, 61 control boys, and 65 control girls. At age 13, girls who had been masculine at age 3 felt less similar to other girls, were less content being a girl, and had greater self-efficacy for male-typed activities than control girls, and girls who had been feminine at age 3 had greater self-efficacy for female-typed activities. Boys who had been feminine at age 3 felt less similar to other boys and had lower self-efficacy for male-typed activities than control boys at age 13, and boys who had been masculine at age 3 felt more competent in agentic roles. Thus, sex-typed behavior at age 3 predicted sex-typed behavior at age 13. It was concluded that the degree of sex-typed behavior shown by preschool children is a good indicator of their degree of sex-typed behavior following the transition to adolescence.

SUMMARY Sixty seven hypertensive children age 2-18 with at least one possible clinical sign of renovascular hypertension (RVH) were enrollment into a screening program for diagnose and treatment of RVH over a 19 year period. Patients underwent a variety of biochemical and imaging studies, but in all cases, renal arteriography was used to determine the precise diagnosis and treatment strategy. Of the 67 patients 21 (31.3%) were identified with renal artery stenosis Group 1, 14 (66.6%) unilateral, 5 (23.8%) bilateral and 2 (9.6%) branches. The mean age was 13.9 +/- 3.73 years, with 26.4 +/- 35.2 months of known hypertension, mean systolic blood pressure 191.1 +/- 30.6 mmHg, mean diastolic blood pressure 135.3 +/- 21.2 mmHg and 69% due to fibromuscular dysplasia. Three therapeutic modalities were chosen: percutaneous transluminal angioplasty (PTA), surgery (autotransplant, and nephrectomy), pharmaceutical therapy with antihypertensive drugs and combination of these. The aim of the treatment was blood pressure control, prevention of chronic renal disease and renal function and organ damage preservation. The outcome was categorized as cure, improvement or no change in hypertension. PTA treated eleven patients, 2 combined with surgery (one nephrectomy and 1 autotransplant). Blood pressure was normalized in 9/11 (81.8%) after a mean follow-up of 11.5 years (range 1-18 years). All 6 RVH cases treated by surgery procedure (one after PTA) were cured and 4 cases were managed medically (pharmacological treatment). On december 2004, 19/21 (90%) RVH adolescents blood pressure was normalized with normal serum creatinina, 10 (48%) of these completed cured, 9/21 (43%) improved (normotensión with decrease in medication requirements) and 2 (9%) other cases ware lost of follow-up. The 46 non-RVH adolescents (68.7%) were treated with long term antihypertensive medications; all of these have adequate BP control and normal renal function. We conclude that our work-up used in order to

Background: Body mass index (BMI) is a commonly used anthropometric measurement to estimate the level of nutritional indices (underweight/overweight) of adolescents and adults. Knowledge of the factors affecting BMI is essential for developing intervention programs. This study was conducted to measure BMI and determine the socioeconomic and demographic factors affecting the relative weight of adolescents living in rural districts in Ethiopia. Methods: A randomized cross-sectional study of 425 adolescent students living in the Ambo region of Ethiopia was conducted. A pre-tested questionnaire was used to collect the socioeconomic and demographic status of the participants. BMI (weight/height2, kg/m2) was measured and used as index of relative weight. Data were analyzed using SPSS version 15. A stepwise backward logistic regression analysis was applied to identify the major determinant abnormal weight of the adolescents while controlling for co-linearity. Results: The prevalence of underweight was 27.2% with male preponderance. The proportion of normal weight females was higher than that of males. There was no significant difference in the proportion of overweight males and females. Age, number of meals, parental education level, source of food, and number of cattle owned were correlated with being underweight. After adjusting for confounding variables only being a member of the younger age group (AOR=1.99; 95% CI=1.01 to 3.57), source of food (AOR=2.4; 95% CI=1.24 to 4.74), and a greater number of cattle owned (AOR=4.9; 95% CI=1.27 to 19.28 were positively correlated with being underweight. Conclusion: Younger age adolescents, those who come from homes with no or few cattle, and their parents purchased food were likely to be underweight. This study will help local governments, educators and community groups develop programs to assist underweight adolescents attending schools. PMID:23675209

Fibroblast growth factor 19 (FGF19) is a hormone released from the small intestine; recently, it has emerged as an endocrine regulator of glucose and lipid metabolism. The aim of this study was to investigate the role of FGF19 in the development of nonalcoholic fatty liver disease (NAFLD). This study included 23 (17 boys) obese adolescents (mean age of 14.1 years) with NAFLD. The control group consisted of 34 (13 boys) obese peers with normal ultrasonographic imaging and normal liver function tests. The definition of NAFLD was based on clinical criteria: elevated alanine aminotransferase (>35 U/L) and liver steatosis features on ultrasound imaging. Serum FGF19 levels were measured in a fasting blood sample. The definition of insulin resistance was based on the homeostasis model assessment (HOMA) threshold: >2.5. There was a significant difference between mean FGF19 levels in patients with NAFLD and controls (142.2 vs. 206 pg/mL, p=0.04). Mean fasting FGF19 levels were decreased in insulin-resistant patients in comparison with the non-insulin-resistant group (155.0 vs. 221.0 pg/mL, p=0.05). There was an inverse correlation between FGF19 and alanine aminotransferase levels (R=-0.3, p<0.05) and triglycerides (R=-0.27, p<0.05). A decrease in fasting FGF19 is associated with the development of NAFLD in obese adolescents. A decrease in fasting FGF19 levels may be a new important risk factor for NAFLD and the metabolic syndrome in adolescents. Further studies are needed to explain whether exogenous delivery of FGF19 might be therapeutically beneficial.

We hypothesized that adolescent oligomenorrhea (ages 14-19) would independently predict impaired fasting glucose (IFG; ≥110 to <126 mg/dL) plus type 2 diabetes mellitus (T2DM; ≥126 mg/dL), insulin and glucose levels, and insulin resistance (IR) in young adulthood (ages 19-25). A prospective 15-year follow-up of 370 schoolgirls starting at age 10 was performed. Age 14 waist circumference was the most important explanatory variable for IFG + T2DM during ages 19 to 24 (P = .002; odds ratio, 1.06; 95% confidence interval, 1.02-1.10), along with oligomenorrhea category from ages 14 to 19 (0, 1, 2, ≥3 reports over 6 years; P = .032; odds ratio, 1.82; 95% confidence interval, 1.05-3.14). Impaired fasting glucose + T2DM at ages 19 to 24 were more common in girls having 1 (6%), 2 (11%), and ≥3 (38%) oligomenorrhea reports from ages 14 to 19 than in girls without oligomenorrhea (3%; P = .0003). Positive explanatory variables (all Ps ≤ .05) for homeostasis model assessment of IR at ages 19 to 24 included age 14 waist (partial R(2) = 30.1%), oligomenorrhea with hyperandrogenism (polycystic ovary syndrome; partial R(2) = 4.1%), black race (3.8%), and oligomenorrhea frequency during ages 14 to 19 (0.8%); sex hormone binding globulin was a negative explanatory variable (0.7%). This is the first prospective study to report an independent association of adolescent oligomenorrhea with young adult IFG + T2DM, with insulin and glucose levels, and with IR. Age 14 waist circumference, oligomenorrhea with hyperandrogenism (polycystic ovary syndrome), black race, oligomenorrhea frequency at ages 14 to 19, and age 14 sex hormone binding globulin were independently associated with IR at ages 19 to 24, potentially facilitating primary prevention of IFG, T2DM, and hyperinsulinemia.

To update the prevalence of overweight and obesity in children and adolescents from 2015. Data for this study were obtained from children and adolescents aged 7-17 years with measured weight and height from the National Surveys on Chinese Students' Constitution and Health in 2015. Measurements from 29 418 children and adolescents (14 480 boys and 14 938 girls) were analysed. Among children and adolescents aged 7-17 years, the prevalence of obesity was 13.2% (95% CI = 12.8-13.7%) in 2015. Moreover, the prevalence of obesity for children aged 7-12 years (20.3% (95% CI = 19.5-21.1%)) was significantly higher than in adolescents aged 13-17 years (9.6% (95% CI = 9.2-10.0%)) (p < 0.001). Obesity was much worse in children than adolescents in China; future studies are warranted to understand why these differences may be occurring.

Food-related Beliefs of Adolescent Girls Ages 9-13 and Their Mothers on O'ahu, Hawai'i.

Mosley, Michelle; Delormier, Treena; Banna, Jinan

2016-04-01

A number of factors contribute to the development of obesity in adolescents, including various dietary and lifestyle behaviors, and a host of social and environmental factors, such as socioeconomic status, parental education, and culture. Research examining beliefs about behaviors related to weight status in adolescents, such as food intake, can create a better understanding of risk factors for obesity. This study explored beliefs about behaviors related to weight status in 20 early adolescent girls aged 9 to 13 years and their mothers in O'ahu, Hawai'i. Semi-structured individual interviews were conducted to elucidate beliefs through discussion of food purchasing, feeding practices, portion control strategies, eating outside the home, and body size perception. Interviews were transcribed verbatim and examined using directed content analysis. Both mothers and daughters believed that diets should consist of fresh foods and be based on principles of variety, balance, and moderation, and had negative perceptions of school lunch. In describing ideal body size, mothers expressed greater concern for overweight, as well as ethno-cultural beauty standards, than daughters. Mothers believed daughters should have a positive relationship with food but also applied various portion control strategies with them. Findings reveal how mothers' and daughters' beliefs may influence daily food-related practices in adolescent girls. Future studies may seek to investigate the role these factors may play in determining weight status in adolescents in Hawai'i, with findings to be used to inform health promotion programs.

Several distributions of country-specific blood pressure (BP) percentiles by sex, age, and height for children and adolescents have been established worldwide. However, there are no globally unified BP references for defining elevated BP in children and adolescents, which limits international comparisons of the prevalence of pediatric elevated BP. We aimed to establish international BP references for children and adolescents by using 7 nationally representative data sets (China, India, Iran, Korea, Poland, Tunisia, and the United States). Data on BP for 52 636 nonoverweight children and adolescents aged 6 to 19 years were obtained from 7 large nationally representative cross-sectional surveys in China, India, Iran, Korea, Poland, Tunisia, and the United States. BP values were obtained with certified mercury sphygmomanometers in all 7 countries by using standard procedures for BP measurement. Smoothed BP percentiles (50th, 90th, 95th, and 99th) by age and height were estimated by using the Generalized Additive Model for Location Scale and Shape model. BP values were similar between males and females until the age of 13 years and were higher in males than females thereafter. In comparison with the BP levels of the 90th and 95th percentiles of the US Fourth Report at median height, systolic BP of the corresponding percentiles of these international references was lower, whereas diastolic BP was similar. These international BP references will be a useful tool for international comparison of the prevalence of elevated BP in children and adolescents and may help to identify hypertensive youths in diverse populations. © 2015 American Heart Association, Inc.

Medora, N P; Goldstein, A; von der Hellen, C

1994-10-01

Feelings of romanticism and self-esteem among pregnant adolescents, adolescent mothers, and a control group of nonpregnant, nonparenting adolescents were investigated. The Bachman Self-Esteem Scale (Bachman, O'Malley, & Johnston, 1978) and the Dean Romanticism Scale (Dean, 1961) were distributed to 649 U.S. female adolescents--255 pregnant adolescents, 121 adolescent mothers, and 273 teenagers in the control group. For romanticism, the results indicated a significant main effect for group (pregnant teens, teen mothers, and a control group consisting of nonpregnant, nonparenting teenagers) and ethnicity (White, Hispanic, African American, and Asian) but not for age (13 to 15 years and 16 to 19 years). The pregnant teens and teen mothers thus had a higher degree of romanticism than the control group did. For self-esteem, there was a significant main effect for race, but not for group or for age. This main effect was qualified by a significant interaction between ethnicity and age.

Marriage patterns and some issues related to adolescent marriage in Bangladesh.

PubMed

Islam, M M; Mahmud, M

1996-09-01

Data from the 1989 Bangladesh Fertility Survey are used to examine marriage patterns among adolescents, factors associated with adolescent marriage, and socioeconomic characteristics of married adolescents. Findings indicate that 100% of females married before the age of 30 years. The proportion of those never married increased after 1974 and among females aged 10-14 years and 15-19 years. The proportion of those never married increased from 73.4% to 95.8% among women aged 10-14 years and from 11.3% to 48.6% among women aged 15-19 years. In 1989 only 4% were married after age 20. 55% of total marriages occurred among women aged 13-15 years. 80% of total marriages occurred under 16 years of age. The highest mean age of marriage was found among women aged 20-29 years at the time of the survey. 63.9% of women who married before the age of 20 years married after menarche, 18.1% married before menarche, and 18.0% married during menarche. The average age at menarche was 13.4 years. 13.9% of marriages were dissolved among women who married before the age of 20 years, and 46% remarried. 8.5% of marriages were dissolved among ever married women who married after the age of 20 years, and only 24.4% remarried. Teenage marriage was more prevalent in rural areas and in Dhaka division, followed by Rajshahi division. About 70% of married adolescents were illiterate or had no formal education, and almost 86% did not work outside the home. Only 26% of married adolescents had husbands with more than a primary education. Marriages took place earlier among families with some land. 92.6% of married adolescents lived in poorly constructed housing. Logistic findings indicate that female education was closely associated with an increased chance of adolescent marriage. Low age at marriage was also influenced strongly by husband's occupation. Regional differences were significant covariates.

Age and gender differences in children and adolescents' attitudes toward noise.

PubMed

Warner-Czyz, Andrea D; Cain, Sarah

2016-01-01

Most school-aged children experience exposure to hazardous sound levels via high-risk noise activities (e.g. loud music/concerts, firearms). Little information exists regarding factors influencing pediatric engagement in these activities and use of hearing protection devices. This study explores effects of age, gender, and attitudes toward noise on participation in acoustic risk-taking behaviors and hearing conservation practices in children and adolescents. Cross-sectional. Children and adolescents (10-19 years) with normal hearing. Most children and adolescents (86.5%) participate in at least one potentially high-risk noise behavior. The most frequently cited activities include sporting events, concerts, and playing a musical instrument. Use of hearing protection devices varies by activity, with consistent wear while using firearms but inconsistent application during all other activities. Gender, but not age, influences acoustic risk-taking behaviors: Boys engage in significantly more high-risk noise activities than girls. Participants expressed a neutral attitude toward noise that persisted across age and gender, but a trend shifting toward a pro-noise attitude emerges in later adolescence. The proliferation of acoustic risk-taking behaviors and lack of hearing conservation practices in children and adolescents requires attention at an early age to prevent future noise-induced hearing loss and subsequent quality of life effects.

Helgeland, Helene; Sandvik, Leiv; Mathiesen, Kristin S; Kristensen, Hanne

2010-04-01

To investigate maternal and child emotional symptoms, physical health problems, and negative life events measured at children's age 18 months and 12 years as potential predictors for self-reported recurrent abdominal pain (RAP) in adolescents (14 years). A population-based prospective study conducted at child health clinics (preventive health care) in Norway followed a cohort of 916 mothers with children from children's age 18 months until adolescence. Child self-report was obtained from 12 years of age. Outcome measure was adolescent self-reported RAP. Of 456 adolescents, 58 (13%) reported RAP. Of these, 36 (62%) were girls. By multivariate analyses, the following maternal factors predicted RAP in adolescence: psychological distress at children's age 18 months (OR, 2.5; 95% CI, 1.3-4.8) and a maternal history of psychological distress at children's age 12 years (OR, 3.2; 95% CI, 1.7-6.2). The following child factors measured at age 12 years predicted RAP in adolescence: abdominal (OR, 2.5; 95% CI, 1.3-4.9) and extraintestinal pain (OR, 2.3; 95% CI, 1.2-4.4) by maternal report, self-reported frequent extraintestinal pain (OR, 2.9; 95% CI, 1.4-5.9), and self-reported depressive symptoms (OR, 2.4; 95% CI, 1.1-5.1). Negative life events and physical health in mothers and toddlers did not predict RAP. This is the first cohort study that finds maternal psychological distress in early childhood to predict RAP in their offspring 13 years later. Our results support that maternal psychological distress and preadolescent children's depressive and somatic symptoms may play a role in the development of RAP. Copyright 2010 Elsevier Inc.

2014-09-01

This study examined links between parents' exercise habits and adolescents' participation in sports activities, considering the aspects of gender and age. It was hypothesized that regular exercise by both parents would be related to children's involvement in sport regardless of their gender and age. Moreover, it was hypothesized that children's sports activities would be more strongly related to their father's exercise activities. The study also examined the links between parents' exercise habits and children's motivation for sports. It was hypothesized that competition motives would be more important for children whose parents exercised regularly. The research sample included 2335 students from the seventh (n = 857), ninth (n = 960) and eleventh (n = 518) grades of various Lithuanian schools. The study used a questionnaire survey method, which revealed the links between parents' exercise habits and their children's participation in sport. Assessment of data for girls and boys showed that daughters' participation in sport could be predicted by both their fathers' and mothers' exercise habits, but sons' sports activities could be predicted only by the regular physical activities of their fathers. The assessment of children's sporting activities according to age revealed links between parental exercising and the engagement of older (15-16 years old), but not younger adolescents (13-14 years old). Analysis of sports motivation showed that competition motives were more important for boys than for girls. Fitness, well-being and appearance motives were more important for older adolescents (15-18 years old), while competition motives were more important for younger adolescents (13-14 years old). Research revealed the relationship between children's sport motives and fathers' exercise habits, while examination of mothers' exercise revealed no difference. Key pointsParental exercising significantly predicts adolescents' engagement in sport. Daughter's engagement in sport is

The regulation of emotions in adolescents: Age differences and emotion-specific patterns

PubMed Central

Theurel, Anne

2018-01-01

Two experiments addressed the issue of age-related differences and emotion-specific patterns in emotion regulation during adolescence. Experiment 1 examined emotion-specific patterns in the effectiveness of reappraisal and distraction strategies in 14-year-old adolescents (N = 50). Adolescents were instructed to answer spontaneously or to downregulate their responses by using either distraction or cognitive reappraisal strategies before viewing negative pictures and were asked to rate their emotional state after picture presentation. Results showed that reappraisal effectiveness was modulated by emotional content but distraction was not. Reappraisal was more effective than distraction at regulating fear or anxiety (threat-related pictures) but was similar to distraction regarding other emotions. Using the same paradigm, Experiment 2 examined in 12-year-old (N = 56), 13-year-old (N = 49) and 15-year-old adolescents (N = 54) the age-related differences a) in the effectiveness of reappraisal and distraction when implemented and b) in the everyday use of regulation strategies using the Cognitive Emotion Regulation Questionnaire. Results revealed that regulation effectiveness was equivalent for both strategies in 12-year-olds, whereas a large improvement in reappraisal effectiveness was observed in 13- and 15-year-olds. No age differences were observed in the reported use of reappraisal, but older adolescents less frequently reported using distraction and more frequently reported using the rumination strategy. Taken together, these experiments provide new findings regarding the use and the effectiveness of cognitive regulation strategies during adolescence in terms of age differences and emotion specificity.

This study assessed the prevalence and influence of exposure to pro-tobacco advertisements among adolescents in 20 low and middle income countries (LMICs). The 2007-2008 Global Youth Tobacco Survey was analyzed for students aged 13-15 years in 20 LMICs. Overall and sex-specific prevalence of exposure to tobacco advertisements in several media, as well as the prevalence of smoking susceptibility (i.e., the lack of a firm commitment among never smokers not to smoke in the future or if offered a cigarette by a friend) were assessed. The variability of the point estimates was assessed using 95% confidence intervals (CI). Logistic regression was used to assess the effect of exposure to multiple (i.e., ≥2) pro-tobacco advertisements on current smoking, adjusting for age and sex (P < 0.05). Data were weighted and analyzed with Stata version 11. Overall country-specific prevalence for different advertisement sources ranged as follows: movies/videos (78.4% in Lesotho to 97.8% in Belize); television programs (48.7% in Togo to 91.7% in the Philippines); newspapers/magazines (29.5% in Togo to 89.7% in the Philippines); and outdoor community events (30.6% in Rwanda to 79.4% in the Philippines). The overall proportion of never smokers who were susceptible to cigarette smoking ranged from 3.7% in Sri Lanka to 70.1% in Kyrgyzstan. Exposure to ≥2 sources of pro-tobacco advertisements was associated with significantly increased odds of cigarette smoking among adolescents in several countries including South Africa (adjusted odds ratio, aOR = 4.11; 95% CI:2.26-7.47), Togo (aOR = 3.77; 95% CI:1.27-11.21), the Former Yugoslav Republic of Macedonia (aOR = 1.42; 95% CI:1.01-1.99), Republic of Moldova (aOR = 1.53; 95% CI:1.11-2.12), Belize (aOR = 13.95; 95% CI:1.91-102.02), Panama (aOR = 5.14; 95% CI: 2.37-11.14) and Mongolia (aOR = 1.52; 95% CI:1.19-1.94).

Data from the National Vital Statistics System •During 1999-2014, the cancer death rate for children and adolescents aged 1-19 years in the United States declined 20%, from 2.85 to 2.28 per 100,000 population. •The cancer death rate for males aged 1-19 years in 2014 was 30% higher than for females. •Declines in cancer death rates during 1999-2014 were experienced among both white and black persons aged 1-19 years and for all 5-year age groups. •During 1999-2014, brain cancer replaced leukemia as the most common cancer causing death among children and adolescents aged 1-19 years, accounting for 3 out of 10 cancer deaths in 2014. Since the mid-1970s, cancer death rates among children and adolescents in the United States showed marked declines despite a slow increase in incidence for some of the major types (1-3). These trends have previously been shown through 2012. This data brief extends previous research by showing trends in cancer death rates through 2014 among children and adolescents aged 1-19 years in the United States. Cancer death rates for 1999-2014 are presented and trends are compared for both females and males, by 5-year age group, and for white and black children and adolescents.

Chari, Roopa; Warsh, Joel; Ketterer, Tara; Hossain, Jobayer; Sharif, Iman

2014-01-01

We tested the association between child and parental health literacy (HL) and odds of child and adolescent obesity. We conducted an anonymous cross-sectional survey of a convenience sample of English-speaking child-parent dyads. Newest Vital Sign (NVS) measured HL. We used multivariable logistic regression to test adjusted association between child and parental NVS and obesity. Analyses were stratified for school-aged children (aged 7-11) vs. adolescents (aged 12-19). We surveyed 239 child-parent dyads. Median child age was 11 [inter-quartile range 9-13]; 123 (51%) were male; 84% Medicaid recipients; 27% obese. For children, the odds of obesity [adjusted odds ratio (95% confidence interval)] decreased with higher parent NVS [0.75 (0.56,1.00)] and increased with parent obesity [2.53 (1.08,5.94)]. For adolescents, odds of obesity were higher for adolescents with the lowest category of NVS [5.00 (1.26, 19.8)] and older parental age [1.07 (1.01,1.14)] and lower for Medicaid recipients [0.21 (0.06,0.78)] and higher parental education [0.38 (0.22,0.63)]. Obesity in school-aged children is associated with parental factors (obesity, parental HL); obesity in adolescents is strongly associated with the adolescent's HL. Strategies to prevent and treat obesity should consider limited HL of parents for child obesity and of adolescents for adolescent obesity. Copyright © 2013. Published by Elsevier Ireland Ltd.

To identify factors associated with unprotected sexual activity in females under the age of 15 years. Cross-sectional observational study of sexually active adolescents under the age of 15 seen at a public outpatient gynecology clinic. Data were collected by means of semi-structured interviews (personal information and data on sexuality), clinical examination, and laboratory tests for diagnosis of sexually transmitted infections. Data were analyzed by frequency testing, association of variables (with p <0.05) and multiple correspondence analysis. One hundred sexually active adolescents between the ages of 11 and 14 were interviewed and examined. Of these, 71% declared themselves black; one-third were behind in school; 80% began sexual activity before the age of 13; 58% reported having been victims of violence within the family environment, and 13% had suffered sexual abuse; 77% did not use condoms regularly; and 22% had STIs. Unprotected sexual activity was more frequent with first sexual intercourse before the age of 13, commercial sexual exploitation, multiple sexual partners, intrafamily violence and school delay, as well as black race, unexpected pregnancy, and STIs. The multiple types of violence suffered by teenagers, including structural, intrafamily, and sexual violence, increase their vulnerability to early, unprotected sexual activity and to STIs and unexpected pregnancy. The synergistic effects of poverty, low educational achievement, and low self-esteem reduces the odds that adolescents will build the tools required for self-protection and exposes them to further victimization outside the family environment.

The Steep Ramp Test in Dutch white children and adolescents: age- and sex-related normative values.

PubMed

Bongers, Bart C; de Vries, Sanne I; Obeid, Joyce; van Buuren, Stef; Helders, Paul J M; Takken, Tim

2013-11-01

The Steep Ramp Test (SRT), a feasible, reliable, and valid exercise test on a cycle ergometer, may be more appealing for use in children in daily clinical practice than the traditional cardiopulmonary exercise test because of its short duration, its resemblance to children's daily activity patterns, and the fact that it does not require respiratory gas analysis. The aim of the present study was to provide sex- and age-related normative values for SRT performance in Dutch white children and adolescents who were healthy and 8 to 19 years old. This was a cross-sectional, observational study. A total of 252 Dutch white children and adolescents, 118 boys (mean age=13.4 years, SD=3.0) and 134 girls (mean age=13.4 years, SD=2.9), performed the SRT (work rate increment of 10, 15, or 20 W·10 s(-1), depending on body height) to voluntary exhaustion to assess peak work rate (WRpeak). Normative values are presented as reference centiles developed by use of generalized additive models for location, scale, and shape. Peak work rate correlated highly with age (r=.915 and r=.811), body mass (r=.870 and r=.850), body height (r=.922 and r=.896), body surface area (r=.906 and r=.885), and fat free mass (r=.930 and r=.902) in boys and girls, respectively. The reference curves demonstrated an almost linear increase in WRpeak with age in boys, even when WRpeak was normalized for body mass. In contrast, absolute WRpeak in girls increased constantly until the age of approximately 13 years, when it started to level off. Peak work rate normalized for body mass in girls showed only a slight increase with age until 14 years of age, when a slight decrease in relative WRpeak was observed. The sample may not have been entirely representative of the Dutch population. The present study provides sex- and age-related normative values for SRT performance in terms of both absolute WRpeak and relative WRpeak, thereby facilitating the interpretation of SRT results by clinicians and researchers.

Eating disorders are very complex, frequently developed and have a public health impact on adolescents. Different studies revealed that eating disorders is a pressing public health problem among adolescents. Eating disorders may also lead to mortality due to their physiological sequelae. There is no previous study regarding disordered of eating attitude in Ethiopian adolescents. Therefore, this study aimed to assess prevalence of disordered eating attitude and its associated factors among adolescents in Addis Ababa high schools. A school-based cross sectional study was conducted. Data were collected among 836 high school adolescents aged 12-19 years from May to June, 2015 in Addis Ababa city. The data were collected by self-administered questionnaire containing eating attitudes test-26 items (EAT-26) and socio-demographic factors. Binary logistic regression analysis was carried out to identify factors associated with disordered eating attitude. Both crude odds ratio and adjusted odds ratio were calculated to show the strength of association. In multivariable analysis, variables with a P value of <0.05 were considered statistically significant. The prevalence of disordered eating attitude among adolescents was 8.6% [95% CI 4.9, 12.3]. Being female [AOR = 1.75, 95% CI 1.03, 3.00], Mother's educational status (Primary [AOR = 0.28, 95% CI 0.11, 0.78], Certificate/diploma [AOR = 0.22, 95% CI 0.07, 0.58] and first degree and above [AOR = 0.16, 95% CI 0.07, 0.40]) were found to be significantly associated with disordered eating attitude. The finding of this study revealed that a significant number of adolescents were susceptible to developing disordered eating attitude. Being female and Mothers' education status were significantly associated with disordered eating attitude among adolescents. Provision of screening test for eating disorders focusing on female adolescents is highly recommended.

Nigeria, Ethiopia and Tanzania have some of the highest teenage pregnancy rates and lowest rates of modern contraceptive use among adolescents. The transdisciplinary Adolescents 360 (A360) initiative being rolled out across these three countries uses human-centred design to create context-specific multicomponent interventions with the aim of increasing voluntary modern contraceptive use among girls aged 15-19 years. The primary objective of the outcome evaluation is to assess the impact of A360 on the modern contraceptive prevalence rate (mCPR) among sexually active girls aged 15-19 years. A360 targets different subpopulations of adolescent girls in the three countries. In Northern Nigeria and Ethiopia, the study population is married girls aged 15-19 years. In Southern Nigeria, the study population is unmarried girls aged 15-19 years. In Tanzania, both married and unmarried girls aged 15-19 years will be included in the study. In all settings, we will use a prepopulation and postpopulation-based cross-sectional survey design. In Nigeria, the study design will also include a comparison group. A one-stage sampling design will be used in Nigeria and Ethiopia. A two-stage sampling design will be used in Tanzania. Questionnaires will be administered face-to-face by female interviewers aged between 18 and 26 years. Study outcomes will be assessed before the start of A360 implementation in late 2017 and approximately 24 months after implementation in late 2019. Findings of this study will be widely disseminated through workshops, conference presentations, reports, briefings, factsheets and academic publications. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Menarche is an important milestone in the development of female adolescents. The study assessed the age at menarche using recall, its seasonality, and association with marital and nutritional status (using mid-upper arm circumference [MUAC]) among 3,923 female adolescents aged 12-19 years in a rural area of Bangladesh. At the time of assessment, most (88%) adolescents had attained menarche at the mean (standard deviation [SD]) age of 12.8 (1.4) years. Age of onset of menarche among married adolescents (13%) occurred earlier than in those who were unmarried (12.6 +/- 1.3 years vs 12.9 +/- 1.4 years, p < 0.01). Age at menarche was negatively associated with MUAC after adjusting for age and marital status (beta = -0.10, p < 0.01). More than 50% of the adolescents had an onset of menarche during winter (chi2 = 634.97; p < 0.001), with peaks in December and January. In this rural population, the current age at menarche was found to be slightly lower than the previous estimates of 13.0 years in Bangladesh. An early onset of menarche was associated with season and better nutritional status of the female adolescents and may be associated with early marriage.

To investigate relationships among youth risk behaviors and demographic factors using an adolescent age group approach. Cross-sectional data from a randomly selected population. Risk behaviors were compared within specific demographic factors and by adolescent age groups. Racially diverse, inner-city neighborhoods in two midwestern cities. Teenagers (n = 1350) and parents (n = 1350) of the teenagers. Truancy; arrested/picked up by police; weapon carrying; fighting; sexual intercourse; tobacco, alcohol, and other drug use; demographic factors; and family structure. Youth mean age was 15.4 (+/- 1.7) years and 52% were female; racial/ethnic characteristics were 47% White, 22% Black, 19% Hispanic, and 10% Native American. Parents' mean age was 42.2 (+/- 8.4) years and 81% were female. chi 2 analyses indicated numerous significant (p < .05) youth risk behavior differences within the demographic factors and that many of the differences varied by adolescent age group. For example, risk behavior differences within racial/ethnic groups were most profound in the middle and older age groups, whereas risk behavior differences within parent income, education levels, and family structure were most apparent in the younger age groups. Of the demographic factors, family structure was most frequently associated with the risk behaviors. The results generally suggest that the relationships among risk behaviors and demographic factors vary within the adolescent age groups included in this study. The results will be useful for developing age-appropriate prevention programs for youth who fit the profile for these risk behaviors. The study protocol also includes specific sampling methods that may be useful for future studies that intend to collect data from difficult-to-reach populations.

Former studies have shown that children and adolescents of divorced parents have significantly poorer educational attainment than their peers from continuously married parents. Educational ambition is important because it has relationship with educational attainment. Our aim was to investigate the associations between parental divorce and educational ambitions among adolescents in the Scandinavian region. Data were used from Young-HUBRO surveys that were conducted in Oslo in the years 2000/2001 and 2004. A change in educational ambition was investigated in a prospective study (n = 1,861) by comparing 18/19 year-olds who experienced late parental divorce with adolescents of continuously married parents. 18/19 year-old adolescents who experienced parental divorce during childhood or adolescence were compared in a cross-sectional study (n = 2,391) with their peers from continuously married parents. Multinomial logistic regression models were fitted to include, among others, mental health problem as a potential confounder. The prospective study showed that a change from ambition for university/college education to having undecided educational ambition was significantly higher among adolescents with experience of late parental divorce than among adolescents of continuously married parents (OR 1.8; 95 % CI 1.1-3.0). In the cross-sectional study, adolescents who experienced parental divorce during childhood or adolescence were more likely to have undecided educational ambition, compared to their peers from continuously married parents (OR 1.3; 95 % CI 1.1-1.8). In conclusion, experience of parental divorce seems to be associated with undecided educational ambition among 18/19 year-old adolescents. Mechanisms that reduce the adverse influence of parental divorce on educational ambitions need to be in place.

Abstract Introduction: Previous studies in adolescents were not adequately powered to accurately disentangle genetic and environmental influences on smoking initiation (SI) across adolescence. Methods: Mega-analysis of pooled genetically informative data on SI was performed, with structural equation modeling, to test equality of prevalence and correlations across cultural backgrounds, and to estimate the significance and effect size of genetic and environmental effects according to the classical twin study, in adolescent male and female twins from same-sex and opposite-sex twin pairs (N = 19 313 pairs) between ages 10 and 19, with 76 358 longitudinal assessments between 1983 and 2007, from 11 population-based twin samples from the United States, Europe, and Australia. Results: Although prevalences differed between samples, twin correlations did not, suggesting similar etiology of SI across developed countries. The estimate of additive genetic contributions to liability of SI increased from approximately 15% to 45% from ages 13 to 19. Correspondingly, shared environmental factors accounted for a substantial proportion of variance in liability to SI at age 13 (70%) and gradually less by age 19 (40%). Conclusions: Both additive genetic and shared environmental factors significantly contribute to variance in SI throughout adolescence. The present study, the largest genetic epidemiological study on SI to date, found consistent results across 11 studies for the etiology of SI. Environmental factors, especially those shared by siblings in a family, primarily influence SI variance in early adolescence, while an increasing role of genetic factors is seen at later ages, which has important implications for prevention strategies. Implications: This is the first study to find evidence of genetic factors in liability to SI at ages as young as 12. It also shows the strongest evidence to date for decay of effects of the shared environment from early adolescence to young adulthood

Motor competence (MC) is an important factor in the development of health and fitness in adolescence. This cross-sectional study aims to explore the distribution of MC across school students aged 13-14 years old and the extent of the relationship of MC to measures of health and fitness across genders. A total of 718 participants were tested from three different schools in the UK, 311 girls and 407 boys (aged 13-14 years), pairwise deletion for correlation variables reduced this to 555 (245 girls, 310 boys). Assessments consisted of body mass index, aerobic capacity, anaerobic power, and upper limb and lower limb MC. The distribution of MC and the strength of the relationships between MC and health/fitness measures were explored. Girls performed lower for MC and health/fitness measures compared with boys. Both measures of MC showed a normal distribution and a significant linear relationship of MC to all health and fitness measures for boys, girls and combined genders. A stronger relationship was reported for upper limb MC and aerobic capacity when compared with lower limb MC and aerobic capacity in boys (t=-2.21, degrees of freedom=307, P=0.03, 95% CI -0.253 to -0.011). Normally distributed measures of upper and lower limb MC are linearly related to health and fitness measures in adolescents in a UK sample. NCT02517333.

Alcohol Binge Drinking and Executive Functioning during Adolescent Brain Development.

Alcohol consumption in adolescents causes negative effects on familiar, social, academic life, as well as neurocognitive alterations. The binge drinking (BD) pattern of alcohol is characterized by the alternation of episodes of heavy drinking in a short interval of time, and periods of abstinence, a practice that can result in important brain alterations; even more than regular alcohol consumption. The prefrontal cortex, which acts as neural support for the executive processes, is particularly affected by alcohol; however, not all studies are in agreement about how BD alcohol consumption affects executive functioning. Some research has found that alcohol consumption in adolescence does not significantly affect executive functioning while others found it does. It is possible that these discrepancies could be due to the history of alcohol consumption, that is, at what age the subjects started drinking. The aim of our study is to assess the performance on executive functioning tasks of 13-19-year-old adolescents according to their pattern of alcohol consumption. We hypothesize that BD adolescents will perform worse than non-BD subjects in tasks that evaluate executive functions, and these differences will increase depending on how long they have been consuming alcohol. Three hundred and twenty-two students (48.14% females; age range 13-22 years; mean aged 16.7 ± 2.59) participated in the study; all of them had begun drinking at the age of 13 years. Participant were divided into three groups, according to their age range (13-15, 16-18, and 19-22 years) and divided according to their pattern of alcohol consumption (BD and control groups). Then, the subjects were evaluated with neuropsychological tasks that assess executive functions like working memory, inhibition, cognitive flexibility, or self-control among others. The entire sample showed a normal improvement in their executive performance, but this improvement was more stable and robust in the control group

To describe traits associated with sexual behaviors in Mexican adolescents, their knowledge about contraception, and factors associated with pregnancy and utilization of contraceptives during first sexual intercourse. Data from the Mexican National Health Survey 2000 (ENSA 2000) were analyzed. This study, conducted between September 1999 and March 2000, was a complex survey with a probabilistic, stratified, and cluster sampling design. The sample population included 15 241 adolescents 12 to 19 years of age. Data analysis included descriptive statistics and a chi-squared test for differences of proportions; also, logistic regression was used to obtain odds ratios. A total of 69.2% adolescents reported knowledge of at least one contraception method; 16.4% of subjects reported having had sexual intercourse. Males initiated sexual intercourse earlier than females and only 37% of all adolescents utilized contraceptives during their first sexual intercourse. Logistic regression analysis showed that being male, having a higher education, having knowledge of at least one contraception method, and having initiated sexual intercourse at an older age, were factors associated with utilization of a contraception method in their first sexual intercourse. A total of 55.7% of sexually active female adolescents had been pregnant. Pregnancy among adolescents was associated with low educational level, sexual activity at early age, and to have sometime lived in free union. The majority of sexually active adolescents did not use contraception during their first sexual intercourse, rendering them at risk of unwanted pregnancies.

Tobacco use is an important risk factor for non-communicable diseases worldwide. However, the global extent and prevalence of tobacco use in adolescents is poorly described. Using previously collected survey data, we aimed to assess tobacco use and second-hand smoke exposure in young adolescents aged 12-15 years in 68 low-income and middle-income countries. We used data from the Global School-based Student Health Survey (2006-13) and the China Global Tobacco Youth Survey (2013), which are school-based surveys of young adolescents aged 12-15 years that assess health behaviours using a standardised, anonymous, self-reported questionnaire. We calculated the prevalence of current tobacco use and exposure to second-hand smoke in young adolescents from 68 low-income and middle-income countries that collected these data in the surveys. We used a multilevel model to estimate the association between parental tobacco use, second-hand smoke, and adolescent tobacco use, adjusting for sex, age, school, school class, country's purchasing power parity, smoking initiation age, national prevalence of tobacco use among adults, year the WHO FCTC was ratified for each country, proxy of socioeconomic status, and survey year. The mean prevalence of current tobacco use was 13·6%, ranging from 2·8% in Tajikistan to 44·7% in Samoa. In most countries, the prevalence of tobacco use was higher for boys than girls, and higher for adolescents aged 14-15 years than for those aged 12-13 years. The overall prevalence of second-hand smoke exposure was 55·9%, ranging from 16·4% in Tajikistan to 85·4% in Indonesia. Parental tobacco use (as reported by the young adolescents), especially maternal use, was associated with tobacco use in young adolescents (odds ratio 2·06, 95% CI 1·93-2·19, for maternal and 1·29, 1·23-1·35 for paternal use). Second-hand smoke exposure was also a risk factor for young adolescents' tobacco use (2·56, 2·43-2·69). However, the prevalence of tobacco use was not

Research on the manifestations and health correlates of eating disorder symptoms among males is lacking. This study identified patterns of appearance concerns and eating disorder behaviors from adolescence through young adulthood and their health correlates. Participants were 7,067 males from the prospective Growing Up Today Study. Surveys from 1999 to 2007 (spanning ages 13-26 years) provided repeated measures data on muscularity and leanness concerns, eating disorder behaviors (purging, overeating, binge eating, use of muscle-building products), and health correlates (obesity, non-marijuana drug use, binge drinking, and depressive symptoms). Latent class analyses of observations at ages 13 to 15, 16 to 18, 19 to 22, and 23 to 26 years identified 1 large Asymptomatic class and 4 symptomatic patterns: Body Image Disturbance (high appearance concerns, low eating disorder behaviors; 1.0%-6.0% per age period); Binge Eating/Purging (binge eating and purging, use of muscle-building products, low appearance concerns; 0.1%-2.5%); Mostly Asymptomatic (low levels of muscularity concern, product use, and overeating; 3.5%-5.0%); and Muscularity Concerns (high muscularity concerns and use of products; 0.6%-1.0%). The Body Image Disturbance class was associated with high estimated prevalence of depressive symptoms. Males in the Binge Eating/Purging and Muscularity Concerns classes had high prevalence of binge drinking and drug use. Despite exhibiting modestly greater appearance concerns and eating disorder behaviors than the Asymptomatic class, being in the Mostly Asymptomatic class was prospectively associated with adverse health outcomes. Results underscore the importance of measuring concerns about leanness, muscularity, and use of muscle-building products when assessing eating disorder presentations among males in research and clinical settings.

The aim of this study was to explain adolescents' volunteering in terms of their morality and identity and to examine the moderation effect of gender and age in this process. Data were collected among 698 Dutch adolescents aged 12 to 20 (M = 15.19; SD = 1.43). Adolescents' moral reasoning was positively associated with understanding moral issues and thinking about public responsibility towards these issues. In turn, moral understanding, along with being personally committed to act upon moral issues, were positively associated with identity. Extending the number of identity contexts tended to be related to being more likely to volunteer and to more volunteering involvement. Adolescents' identity integration was not related to how likely they were to volunteer, and was negatively related to their volunteering involvement. Clearer effects were found when differentiating between adolescent gender and age groups. Future research could examine this process over time, along with additional factors that may further explain adolescents' volunteering, and examine their age and gender specific effects.

The aim of our study was to examine the association between problematic cell phone use (PCPU) for text messaging and substance abuse in young adolescents. This cross-sectional study was conducted on the basis of an ad hoc questionnaire, during the 2014-2015 school year in a province of the Veneto Region (Italy); it involved a sample of 1156 students in grades 6 to 8 (11 to 13 years old). A self-report scale based on the Short Message Service (SMS) Problem Use Diagnostic Questionnaire (SMS-PUDQ) was administered to assess the sample's PCPU. A multivariate logistic regression model was applied to seek associations between PCPU (as the dependent variable) and independent variables. The proportion of students who reported a PCPU increased with age in girls (13.5% in 6th grade, 16.4% in 7th grade, and 19.5% in 8th grade), but not in boys (14.3% in 6th grade, 18.0% in 7th grade, and 14.8% in 8th grade). Logistic regression showed that drunkenness at least once and energy drink consumption raised the odds of PCPU, whereas reading books, higher average school marks, and longer hours of sleep were associated with lower odds of PCPU in early adolescence. our findings confirm a widespread PCPU for text messaging among early adolescents. The odds of PCPU is greater in young people at risk of other substance abuse behavior.

Prior longitudinal studies have shown high cumulative dating violence exposure rates among U.S adolescents, with 36 percent of males and 44 percent to 88 percent of females experiencing victimization across adolescence/young adulthood. Despite promising information characterizing adolescents' dating violence experiences longitudinally, prior studies tended to concentrate on physical and sexual types of violence only, and did not report information on the number of times dating violence was experienced across multiple abusive partners. We used a method similar to the timeline follow-back interview to query adolescents about dating violence victimization from age 13 to 19-including dating violence types (physical, sexual, and psychological), frequency, age at first occurrence, and number of abusive partners. A total of 730 subjects were randomly sampled from university registrar records and invited to complete an online survey, which utilized methods similar to the timeline follow-back interview, to retrospectively assess relationship histories and dating violence victimization from age 13 to 19 (eight questions adapted from widely-used surveys covering physical, sexual, and psychological abuse). Then, for each dating violence type, we asked about the number of occurrences, number of abusive partners, and age at first occurrence. Of 341 subjects who completed the survey, we included 297 (64 percent females; 36 percent males) who had a dating partner from age 13 to 19. Fully 64.7 percent of females and 61.7 percent of males reported dating violence victimization between age 13 and 19, with most experiencing multiple occurrences. More than one-third of abused females had two or more abusive partners: controlling behavior (35.6 percent); put downs/name calling (37.0); pressured sex (42.9); insults (44.3); slapped/hit (50.0); and threats (62.5). Males also had two or more abusive partners, as follows: controlling behavior (42.1 percent); insults (51.2); put downs (53

The aim of this study was to investigate the relation between health-related physical fitness and weight status in 13- to 15-year-old Latino adolescents. The final sample consisted of 73,561 adolescents aged 13-15 years (35,175 girls) from Chile (n=48,771) and Colombia (n=24,790). Cardiorespiratory and musculoskeletal fitness were measured using 20-m shuttle run (relative peak oxygen uptake - VO 2peak ) and standing broad jump test (lower body explosive strength), respectively. The International Obesity Task Force definition was used to define weight status (i.e., underweight, normal weight, overweight, and obese). The present study found an inverted J-shape relationship between body mass index, cardiorespiratory fitness, and musculoskeletal fitness in both genders and all age groups (p<0.01). Results also suggest that underweight adolescents, and not just overweight and obese adolescents, have lower odds of having a healthy cardiorespiratory fitness (based on new international criterion-referenced standards) profile when compared with their normal weight peers, except in girls aged 14 (p=0.268) and 15 years (p=0.280). The present results indicate low cardiorespiratory fitness and musculoskeletal fitness levels in underweight, overweight, and obese adolescents when compared with their normal weight peers. The findings appear to suggest that exercise programs should to decrease fat mass in overweight/obese adolescents and increase muscle mass in underweight adolescents.

To describe the status of snacks consumption, the characteristics, and the contribution to their diet and nutrients intake in Chinese children and adolescents at the ages of 3-17 years. Chinese health and nutritional survey (1991-2004), Chinese National nutrition and health survey (2002), and 2007 typical survey on snacks in Chinese residents were used in this report. The incidence of snacks consumption and snacking contribution were calculated by consecutive day 3 dietary recalls of the first 2 surveys. At least 1 snacks intake in 3 days was snacking consumption. The incidences of snacks consumption in Chinese population at the ages of 3-17 years were increased from 1991 (13.2%) to 2004 (19.3%). There were 35.1% of Chinese children and adolescents consuming snacks, 55.7% in urban and 29.6% in rural. Snacks provided 7.7% of total daily energy, 18.2% of fiber, 17.9% of VC, 9.9% of calcium, 9.7% of VE, 6.9% of iron and 6.3% of zinc. The snacks were mainly consumed in the evening. The main reasons were not nutrition of food but good taste, thirsty or hungry and food advertisement. The location of snacking was mainly at home and school. The snacks came from parents or other family members. They also buy snacks themselves. The consumption of candies and chocolate, jelly more than 4-6 day a week had a certain proportion. It was important to supervise snacks selection and consumption in Chinese children and adolescents at the ages of 3-17 years. The limitations of snacks consumption data perhaps lowed underestimate the effects of snacks to dietary intake.

Adolescent and young adult female determinants of visceral adipose tissue at ages 26-28 years.

To assess adolescent and young adult determinants of visceral adipose tissue (VAT) at ages 26-28 years. Prospective study (ages 9-28 years) of cardiometabolic measures, menarche age, menses irregularities, metabolic syndrome, impaired fasting glucose-type 2 diabetes mellitus, and VAT in 400 girls (248 black, 152 white). Adolescent (age 14-19) independent variables for greater VAT at ages 26-28 included larger mean waist circumference (partial R(2) = 30.8%), earlier age at menarche (0.9%), and white race (1.8%). Young adult (ages 20-28 years) independent variables for greater VAT included larger mean waist circumference (partial R(2) = 61.7%), greater triglyceride levels (3.3%), lower high-density lipoprotein cholesterol (1.0%), and greater insulin resistance (homeostasis model assessment-estimated insulin resistance; 0.4%). Independent variables for greater VAT when both adolescent and young adult variables were used included waist (tertile rank change from adolescence to young adulthood, partial R(2) = 58.3%), greater young adult triglyceride levels (4.4%), white race (1.8%), greater young adult homeostasis model assessment-estimated insulin resistance (age 20-28, 2.4%), and earlier menarche age (0.7%). Menses irregularities were not independently associated with young adult VAT. Adolescent girls with early menarche and larger waist circumference should be targets for primary prevention of accretion of VAT. In young adulthood, VAT is associated with dysregulated cardiometabolic profiles, which is greater for those with waist circumference increases from adolescence to adulthood. Waist circumference during young adulthood, and to a lesser degree during adolescence, is an inexpensive surrogate for VAT at ages 26-28 years. Copyright © 2015 Elsevier Inc. All rights reserved.

Stephenson, Rob; Simon, Calleen; Finneran, Catherine

2014-06-01

Using data from the National Survey of Adolescents (2004), we examine the community-level factors associated with early age at first sex among adolescents 14-19 years old in four African countries. Regression models are fitted separately by sex for each country for an outcome measuring early age at first sex, with a focus on community-level factors as potential influences of age on sexual debut. The community-level factors associated with adolescents' sexual debut vary widely by both country and gender. Community influences that emerge as risk or protective factors of early sexual debut include community levels of adolescent marriage, wealth, religious group affiliation, sex education, parental monitoring, reproductive health knowledge, media exposure, membership in adolescent social group, and use of alcohol. Results indicate the importance of context-specific understanding of adolescents' sexual behaviour and suggest how elements of place should be harnessed in the development of effective HIV and sexual health interventions.

To compare selected characteristics (age, sex, age of onset for depression, impairment, severity of depression, somatic comorbidity, and treatment status) of adolescents with currently comorbid and non-comorbid depression. A sample of 218 consecutive adolescent (13-19 years) psychiatric outpatients with depressive disorders, and 200 age- and sex-matched school-attending controls were interviewed for DSM-IV Axis I and Axis II diagnoses. Current comorbidity, most commonly with anxiety disorders, was equally frequent (>70%) in outpatients and depressed controls. Younger age (OR 0.20; 95% CI 0.08, 0.51) and male gender (OR 0.02; 95% CI 0.09, 0.55) were associated with concurrent disruptive disorders. Current comorbidity with substance use disorders (SUD) was independent of age (OR 1.13; 95% CI 0.51, 2.49) and sex (OR 0.51; 95% CI 0.22, 1.17). Personality disorders associated with older age (OR 2.06; 95% CI 1.10, 3.86). In multivariable logistic regression analysis, impairment (GAF 13; 95% CI 1.53, 6.45), while severity of depression and lifetime age of onset for depression were not. Adolescent depression presents with age- and sex-dependent patterns of multiple co-occurring problem areas. While many clinical characteristics of adolescent depression are not affected by comorbidity, comorbidity associates with increased impairment.

[Sexual Abuse and Neglect Situations as Risk Factors for Adolescent Pregnancy].

PubMed

Restrepo Martínez, Miguel; Trujillo Numa, Laura; Restrepo Bernal, Diana; Torres de Galvis, Yolanda; Sierra, Gloria

In Colombia, one out of five women between the ages of 15 and 19 years have been pregnant. Almost two-thirds (64%) of these pregnancies were unplanned. To examine the socio-demographic, psychosocial and clinical risk factors associated with adolescent pregnancy. An analytical prevalence study was performed using secondary data from the First Demographic Study of Mental Health in Medellin, Colombia. Female adolescents between 13 and 19 years of age were included in the study. The population was evaluated using the Composite International Diagnosis Interview, a structured interview developed by the World Health Organization, which establishes diagnoses according to the DSM-IV and ICD-10 criteria. A sample of 499 female adolescents was obtained, in which 135 adolescent pregnancies were identified, representing a prevalence of 21.5%. The large majority (84.4%) were between 16 and 19 years old. The median age was 17 years, with an interquartile range of 2 years. Almost two-thirds (61.2%) of female adolescents had initiated sexual activity at the age of 15 or later. Almost one-third (31.9%) reported being physically abused during childhood, and 6.7% sexually abused. Of those who were pregnant, 66.7% reported previous sexual abuse. A bivariate analysis showed that sexual abuse (OR=7.68), childhood negligence (OR=4.33), and having a partner (OR=6.31) were factors associated with an adolescent pregnancy. Negligence and sexual abuse in childhood and adolescence can be prevented, and adolescent pregnancies can be decreased. This finding has important implications for clinical management and prognosis, and requires public preventive policies. Copyright © 2016 Asociación Colombiana de Psiquiatría.

To study the types and frequency of problems related to menstruation in adolescent girls and the effect of these problems on daily routine. Girls in the age group 13-19 years who had had menarche for at least one year at the time of study. 198 adolescent girls have been studied. Data was collected by personal interviews on a pre-tested, semi-structured questionnaire. The questions covered menstrual problems, regularity of menses in last three cycles of menstruation and the effect of these problems on the daily routine. Analysis was done using SPSS version 12. Percentages were calculated for drawing inferences. More than a third (35.9%) of the study subjects were in the age group 13-15 years followed by 17-19 years, 15-17 years respectively. Mean age of study participants was calculated to be 16.2 years. Dysmenorrhea (67.2%) was the commonest problem and (63.1%) had one or the other symptoms of Pre-menstrual syndrome (PMS). Other related problems were present in 55.1% of study subjects. Daily routine of 60% girls was affected due to prolonged bed rest, missed social activities/commitments, disturbed sleep and decreased appetite. 17.24% had to miss a class and 25% had to abstain from work. Mothers and friends were the most common source of information on the issue. Screen adolescent girls for menstruation related problems and provide them with counseling services and relevant information on possible treatment options. Besides, there is a need to emphasize on designing menstrual health programmes for adolescents.

Previous studies in adolescents were not adequately powered to accurately disentangle genetic and environmental influences on smoking initiation (SI) across adolescence. Mega-analysis of pooled genetically informative data on SI was performed, with structural equation modeling, to test equality of prevalence and correlations across cultural backgrounds, and to estimate the significance and effect size of genetic and environmental effects according to the classical twin study, in adolescent male and female twins from same-sex and opposite-sex twin pairs (N = 19 313 pairs) between ages 10 and 19, with 76 358 longitudinal assessments between 1983 and 2007, from 11 population-based twin samples from the United States, Europe, and Australia. Although prevalences differed between samples, twin correlations did not, suggesting similar etiology of SI across developed countries. The estimate of additive genetic contributions to liability of SI increased from approximately 15% to 45% from ages 13 to 19. Correspondingly, shared environmental factors accounted for a substantial proportion of variance in liability to SI at age 13 (70%) and gradually less by age 19 (40%). Both additive genetic and shared environmental factors significantly contribute to variance in SI throughout adolescence. The present study, the largest genetic epidemiological study on SI to date, found consistent results across 11 studies for the etiology of SI. Environmental factors, especially those shared by siblings in a family, primarily influence SI variance in early adolescence, while an increasing role of genetic factors is seen at later ages, which has important implications for prevention strategies. This is the first study to find evidence of genetic factors in liability to SI at ages as young as 12. It also shows the strongest evidence to date for decay of effects of the shared environment from early adolescence to young adulthood. We found remarkable consistency of twin correlations across

Adolescent attitudes and relevance to family life education programs.

The study was conducted in seven private coeducational English-medium schools in Cochin to understand adolescent attitudes in this part of the country. Queries submitted by students (n=10,660) and responses to separate pretested questionnaires for boys (n=886 received) and girls (n=589 received) were analysed. The study showed a lacuna of knowledge among adolescents with the most frequently asked queries being on masturbation, and sex and sexuality. More than 50% of adolescents received information on sex and sexuality from peers; boys had started masturbating by 12 yr age and 93% were doing so by 15 yr age. Although 73% of girls were told about menstruation by their parents, 32% were not aware, at menarche, that such an event would occur and only 8% were aware of all aspects of maintaining menstrual hygiene. 19% of boys succumbed to peer pressure into reading/viewing pornography; more than 50% of adolescents admitted to having had an infatuation around 13 yrs of age or after. 13% of boys admitted to having been initiated into smoking by friends; mostly between 14-16 yrs age; 6.5% boys had consumed alcohol with peers or at family functions, starting between ages of 15 to 17 yrs. Though >70% of adolescents were aware about AIDS, adequate knowledge about its spread and prevention was lacking.

A cross-country comparison of the prevalence of exposure to tobacco advertisements among adolescents aged 13–15 years in 20 low and middle income countries

PubMed Central

2013-01-01

Background This study assessed the prevalence and influence of exposure to pro-tobacco advertisements among adolescents in 20 low and middle income countries (LMICs). Methods The 2007–2008 Global Youth Tobacco Survey was analyzed for students aged 13–15 years in 20 LMICs. Overall and sex-specific prevalence of exposure to tobacco advertisements in several media, as well as the prevalence of smoking susceptibility (i.e., the lack of a firm commitment among never smokers not to smoke in the future or if offered a cigarette by a friend) were assessed. The variability of the point estimates was assessed using 95% confidence intervals (CI). Logistic regression was used to assess the effect of exposure to multiple (i.e., ≥2) pro-tobacco advertisements on current smoking, adjusting for age and sex (P < 0.05). Data were weighted and analyzed with Stata version 11. Results Overall country-specific prevalence for different advertisement sources ranged as follows: movies/videos (78.4% in Lesotho to 97.8% in Belize); television programs (48.7% in Togo to 91.7% in the Philippines); newspapers/magazines (29.5% in Togo to 89.7% in the Philippines); and outdoor community events (30.6% in Rwanda to 79.4% in the Philippines). The overall proportion of never smokers who were susceptible to cigarette smoking ranged from 3.7% in Sri Lanka to 70.1% in Kyrgyzstan. Exposure to ≥2 sources of pro-tobacco advertisements was associated with significantly increased odds of cigarette smoking among adolescents in several countries including South Africa (adjusted odds ratio, aOR = 4.11; 95% CI:2.26-7.47), Togo (aOR = 3.77; 95% CI:1.27-11.21), the Former Yugoslav Republic of Macedonia (aOR = 1.42; 95% CI:1.01-1.99), Republic of Moldova (aOR = 1.53; 95% CI:1.11-2.12), Belize (aOR = 13.95; 95% CI:1.91-102.02), Panama (aOR = 5.14; 95% CI: 2.37-11.14) and Mongolia (aOR = 1.52; 95% CI:1.19-1.94). Conclusion Prevalence of exposure to various pro-tobacco advertisements was high among adolescents

Sexual risk factors for partner age discordance in adolescent girls and their male partners.

Morrison-Beedy, Dianne; Xia, Yinglin; Passmore, Denise

2013-12-01

To investigate differences in sexual risk factors between adolescent girls reporting similar-aged or older sex partners. Adolescent girls are at significant risk of heterosexual-acquired HIV infection and other long-term reproductive health issues. Sexual partner age discordance in teen girls has been correlated with STIs, lack of protection, multiple partners and earlier age of sexual transition. A descriptive study comparing girls currently involved with age-discordant partners to those with similar-aged partners. Two-sample t-test for continuous variables and chi-squared test or Fisher's exact test for categorical variables were used to compare groups. Baseline data from 738 sexually active, urban, adolescent girls aged 15-19 were analysed to determine which behaviours were more likely to occur in girls with older partners. Data were collected as part of a gender-specific HIV-prevention intervention in a randomised controlled trial (RCT) tailored to adolescent girls. Multiple reported sexual risk behaviours were found to significantly differ between the two groups at baseline. Overall, girls with older partners had more episodes of sexual instances (vaginal, anal and oral). Specific sexual risk behaviours were found to be statistically significant between the two groups. Girls with older partners started having sex at earlier ages, had more lifetime sexual partners, higher incidents of STIs and were reluctant to discuss using condoms with their partners. Girls with similar-aged partners were less willing to engage in risky sexual behaviours. Findings from this investigation support data from other studies. Relationships with older male partners place adolescent girls at increased risk of HIV/STIs and unintended pregnancy. Adolescent girls in age-discordant relationships are at risk of immediate and long-term sexual health morbidities. Identifying girls who are at increased risk by asking tailored questions will enable nurses to recommend appropriate diagnostics

The severity and course of spinal pain is poorly understood in adolescents. The study aimed to determine the prevalence and two-year incidence, as well as the course, frequency, and intensity of pain in the neck, mid back, and low back (spinal pain). This study was a school-based prospective cohort study. All 5th and 6th grade students (11-13 years) at 14 schools in the Region of Southern Denmark were invited to participate (N=1,348). Data were collected in 2010 and again two years later, using an e-survey completed during school time. The lifetime prevalence of spinal pain was 86% and 89% at baseline and follow-up, respectively. A group of 13.6% (95% CI: 11.8, 15.6) at baseline and 19.5% (95% CI: 17.1, 22.0) at follow-up reported that they had pain frequently. The frequency of pain was strongly associated with the intensity of pain, i.e., the majority of the participants reported their pain as relatively infrequent and of low intensity, whereas the participants with frequent pain also experienced pain of higher intensity. The two-year incidence of spinal pain varied between 40% and 60% across the physical locations. Progression of pain from one to more locations and from infrequent to more frequent was common over the two-year period. Spinal pain is common at the age of 11-15 years, but some have more pain than others. The pain is likely to progress, i.e., to more locations, higher frequency, and higher pain intensity over a two-year period.

Introduction Motor competence (MC) is an important factor in the development of health and fitness in adolescence. Aims This cross-sectional study aims to explore the distribution of MC across school students aged 13–14 years old and the extent of the relationship of MC to measures of health and fitness across genders. Methods A total of 718 participants were tested from three different schools in the UK, 311 girls and 407 boys (aged 13–14 years), pairwise deletion for correlation variables reduced this to 555 (245 girls, 310 boys). Assessments consisted of body mass index, aerobic capacity, anaerobic power, and upper limb and lower limb MC. The distribution of MC and the strength of the relationships between MC and health/fitness measures were explored. Results Girls performed lower for MC and health/fitness measures compared with boys. Both measures of MC showed a normal distribution and a significant linear relationship of MC to all health and fitness measures for boys, girls and combined genders. A stronger relationship was reported for upper limb MC and aerobic capacity when compared with lower limb MC and aerobic capacity in boys (t=−2.21, degrees of freedom=307, P=0.03, 95% CI −0.253 to –0.011). Conclusion Normally distributed measures of upper and lower limb MC are linearly related to health and fitness measures in adolescents in a UK sample. Trial registration number NCT02517333.

Increasing the amount of contact with older persons is often proposed as a way to inform young people about aging. This study compared adolescents' knowledge of aging with the amount and quality of contact they had with an older person and compared knowledge of aging in a 1978 sample of adolescents with knowledge in a 1985 sample.

The objective of this study was to examine the smoking behavior among adolescents in Thailand and Malaysia. Population-based, national surveys were conducted among 1,704 adolescents between the ages of 13 and 18 from Thailand (n = 927) and Malaysia (n = 777). Respondents were selected using multistage cluster sampling. Respondents were asked to complete self-administered questionnaires. Approximately 5% of Thai and Malaysian adolescents were current smokers, while an additional 8.6% of Thai and 8.1% of Malaysian adolescents reported being beginning smokers. On average, Thai smokers reported first smoking a whole cigarette at 14.6 years old (SD = 1.9), while Malaysian smokers at age 13.9 years (SD = 2.2). More than half of Thai smokers (60.4%) reported they bought cigarettes themselves and 29.9% got cigarettes from friends. In Malaysia, most smokers (68.3%) reported they bought cigarettes themselves, only 20.7% got cigarettes from friends. Seventy-six percent of Thai adolescent smokers smoked factory-made brands as their usual brand compared to 27.7% of Malaysian adolescent smokers. Eight percent of Thai adolescents and 10% of Malaysian adolescents reported smoking hand-rolled cigarettes. Approximately half of Thais and more than 40% of Malaysian smokers reported they tried to quit smoking within the past month. The smoking prevalence of Thai adolescents is close to that of Malaysian adolescents. Factory-made cigarette consumption is an important problem in Thai adolescents and needs to be targeted.

Developmental changes in parent-child communication throughout adolescence.

PubMed

Keijsers, Loes; Poulin, François

2013-12-01

This study examined how parent-child communication regarding adolescent unsupervised activities develops over the course of adolescence. We used questionnaire data from 390 adolescents (58% girls; 90% European Canadian) who were followed from age 12 to 19. Latent growth curve modeling revealed curvilinear developmental changes that differed for boys and girls. From age 14 to 19 (but not from age 12 to 14) a linear decrease in parental control was found for both genders. For girls, parent-child communication decreased in early adolescence, as indicated by decreasing parental solicitation, decreasing adolescent disclosure, and increasing secrecy. Girls' communication with parents intensified in middle adolescence, as indicated by increasing parental solicitation, increasing adolescent disclosure, and decreasing adolescent secrecy. For boys, disclosure declined in early adolescence, but secrecy and solicitation were stable throughout adolescence. Parental knowledge decreased from age 12 to 19 for both genders but was temporarily stable for middle adolescent girls. The meaning of these developmental changes, their timing, and gender differences are discussed. PsycINFO Database Record (c) 2013 APA, all rights reserved.

Physical activity (PA) declines as adolescents get older, and the motivational determinants of PA warrant further investigation. The purposes of this study were to investigate the amount of physical and sedentary activity that adolescents participated in across age, gender, and race, and to investigate adolescents' attraction to PA and their perceived barriers and benefits across age, gender, and race. High school students (N = 1163) aged between 13 and 16 years completed questionnaires on minutes and intensity of physical and sedentary activity, interests in physical activity, and perceived benefits and barriers to participating in PA. A series of multivariate analyses of variance were conducted and followed up with discriminant function analysis. PA participation decreased in older females. In addition, fun of physical exertion was a primary attraction to PA for males more than females. Body image as an expected outcome of participating in PA contributed most to gender differences. There is a need to determine why PA drops-off as females get older. Findings underscore the importance of structuring activities differently to sustain interest in male and female adolescents, and highlights motives of having a healthy body image, and making PA fun to enhance participation.

Accurate measurement of body composition in children and adolescents is important as the quantities of fat and fat-free mass have implications for health risk. The objectives of the present study were: to determine the reliability of Fourier Transform Infrared spectroscopy (FTIR) measurements and; compare the Fat Mass (FM), Fat Free Mass (FFM) and body fat percentage (%BF) values determined by bioelectrical impedance analysis (BIA) to those determined by deuterium dilution method (DDM) to identify correlations and agreement between the two methods. A cross-sectional study was conducted among 203 children and adolescents aged 8-19 years attending schools in Kampala city, Uganda. Pearson product-moment correlation at 5% significance level was considered for assessing correlations. Bland Altman analysis was used to examine the agreement between of FTIR measurements and between estimates by DDM and BIA.. Reliability of measurements was determined by Cronbach's alpha. There was good agreement between the in vivo D 2 O saliva enrichment measurements at 3 and 4 h among the studied age groups based on Bland-Altman plots. Cronbach's alpha revealed that measurements of D 2 O saliva enrichment had very good reliability. For children and young adolescents, DDM and BIA gave similar estimates of FFM, FM, and %BF. Among older adolescents, BIA significantly over-estimated FFM and significantly under-estimated FM and %BF compared to estimates by DDM. The correlation between FFM, FM and %BF estimates by DDM and BIA was high and significant among young and older adolescents and for FFM among children. Reliability of the FTIR spectroscopy measurements was very good among the studied population. BIA is suitable for assessing body composition among children (8-9 years) and young adolescents (10-14 years) but not among older adolescents (15-19 years) in Uganda. The body composition measurements of older adolescents determined by DDM can be predicted using those provided by BIA using

Recent years have seen increased coverage of adolescent victimization and suicide. Both adolescent peer victimization and substance use have been associated with suicidal ideation, with evidence suggesting that all three factors are interrelated. There are at least four models which can explain the associations between these factors (i.e., self-medication, secondary mental disorder, bidirectional, and common factor). However, none of them is being empirically supported as the dominant model because few longitudinal studies have explored the association between these factors. The present study compared longitudinal paths of all four models simultaneously using a cross-lagged model. This was done using self-reported measures of peer victimization, suicidal ideation, and alcohol use at age 13, 14, and 15 years in a longitudinal sample of 238 adolescents. All three variables were moderately stable across time. Significant cross-lagged associations were found, showing that frequent peer victimization at age 13 years was associated with higher odds of having suicidal ideation at age 14 years (odds ratio, 1.82; p < .05). In turn, presence of suicidal ideation at age 14 years was significantly associated with higher alcohol use frequency at age 15 years (β = .13; p < .05). Results support previous literature suggesting that peer victimization predates alcohol use and extends it by showing clear directionality between suicidal ideation and alcohol use over 1 year, supporting the self-medication model. Clarifying the empirical basis of these underlying models could allow for earlier prevention strategies, by targeting the risk factor that appears the earliest in the model.

In Search of Emerging Same-Sex Sexuality: Romantic Attractions at Age 13 Years.

PubMed

Li, Gu; Hines, Melissa

2016-10-01

Sex-typed behavior in childhood is significantly related to sexual orientation in adulthood. In addition, same-sex attractions in early adolescence are more non-exclusive than in adulthood and can differ from later same-sex orientations. However, little research has focused on romantic attractions as they emerge during early adolescence. Drawing a sample from the Avon Longitudinal Study of Parents and Children (197 girls, 204 boys), the current study examined whether same-sex romantic attractions at age 13 years were exclusive, and whether they were predicted by sex-typed behavior at age 3.5 years. No young adolescents in this sample reported exclusive same-sex attractions, and increased same-sex attractions were not significantly related to reduced other-sex sexualities. Childhood sex-typed behavior did not significantly predict early same-sex attractions, suggesting that early same-sex attractions differ from later same-sex orientations. The current study highlights the importance of studying the development of sexuality beginning prior to adulthood.

Dating violence victimization across the teen years: Abuse frequency, number of abusive partners, and age at first occurrence

PubMed Central

2012-01-01

Background Prior longitudinal studies have shown high cumulative dating violence exposure rates among U.S adolescents, with 36 percent of males and 44 percent to 88 percent of females experiencing victimization across adolescence/young adulthood. Despite promising information characterizing adolescents’ dating violence experiences longitudinally, prior studies tended to concentrate on physical and sexual types of violence only, and did not report information on the number of times dating violence was experienced across multiple abusive partners. We used a method similar to the timeline follow-back interview to query adolescents about dating violence victimization from age 13 to 19—including dating violence types (physical, sexual, and psychological), frequency, age at first occurrence, and number of abusive partners. Methods A total of 730 subjects were randomly sampled from university registrar records and invited to complete an online survey, which utilized methods similar to the timeline follow-back interview, to retrospectively assess relationship histories and dating violence victimization from age 13 to 19 (eight questions adapted from widely-used surveys covering physical, sexual, and psychological abuse). Then, for each dating violence type, we asked about the number of occurrences, number of abusive partners, and age at first occurrence. Of 341 subjects who completed the survey, we included 297 (64 percent females; 36 percent males) who had a dating partner from age 13 to 19. Results Fully 64.7 percent of females and 61.7 percent of males reported dating violence victimization between age 13 and 19, with most experiencing multiple occurrences. More than one-third of abused females had two or more abusive partners: controlling behavior (35.6 percent); put downs/name calling (37.0); pressured sex (42.9); insults (44.3); slapped/hit (50.0); and threats (62.5). Males also had two or more abusive partners, as follows: controlling behavior (42.1 percent

The available estimates reveal that 20–50% of adolescents report depressive symptoms, being one of the most prevalent health problems in adolescence. The aim of this study was to assess the prevalence of depressive symptoms in a community sample of 13-year-old adolescents and identify associated features. Thirteen year-old adolescents attending private and public schools in Porto (n = 1,988, 52.2% females) were evaluated from October 2003 to June 2004 and completed a questionnaire including health behaviors and the Beck Depression Inventory II. A questionnaire on parents’ socio-demographics and clinical characteristics was sent home. Data were analyzed separately by sex. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using logistic regression. The prevalence of depressive symptoms was 18.8% in girls and 7.6% in boys (p < 0.001). Boys with a family history of depression and girls with smoking habits had a significantly increased risk of depressive symptoms (OR = 2.18, 95%CI 1.00–4.71; OR = 2.34, 95%CI 1.46–3.76). Menarche at an early age significantly increased the risk of depressive symptoms. The characteristics most strongly associated with depressive symptoms were family history of depression among boys, tobacco consumption and an early age at menarche among girls. The high prevalence of depressive symptoms early in adolescence calls for the awareness of public health professionals. PMID:24129117

Time to symptom resolution, return to school, and return to play after a sport-related concussion in children and adolescents (8-17 years of age) was examined using a retrospective cohort design. A total of 198 patients aged 8 to 17 years were included, with a mean age of 13.5 years (SD = 2.2). Patients aged 8 to 12 years were symptom-free in a median of 12.0 (range 1-60) days whereas 13- to 17-year olds were symptom-free in a median of 14.0 (range 1-300) days (P = .04). Patients aged 8 to 12 years returned to learn in a median of 4.0 (range 0-30) days compared with 2.5 (range 0-55.0) days in 13- to 17-year-olds (P = .86). Patients aged 8 to 12 years returned to play in a median of 14.0 (range 4-75) days compared with a median of 19.5 (range 5-75) days in 13- to 17-year-olds (P = .06). These results indicate that children and adolescents generally take 2 to 4 weeks to recover from a sport-related concussion. © The Author(s) 2015.

Age differences in the impact of peers on adolescents' and adults' neural response to reward.

PubMed

Smith, Ashley R; Steinberg, Laurence; Strang, Nicole; Chein, Jason

2015-02-01

Prior research suggests that increased adolescent risk-taking in the presence of peers may be linked to the influence of peers on the valuation and processing of rewards during decision-making. The current study explores this idea by examining how peer observation impacts the processing of rewards when such processing is isolated from other facets of risky decision-making (e.g. risk-perception and preference, inhibitory processing, etc.). In an fMRI paradigm, a sample of adolescents (ages 14-19) and adults (ages 25-35) completed a modified High/Low Card Guessing Task that included rewarded and un-rewarded trials. Social context was manipulated by having participants complete the task both alone and while being observed by two, same-age, same-sex peers. Results indicated an interaction of age and social context on the activation of reward circuitry during the receipt of reward; when observed by peers adolescents exhibited greater ventral striatal activation than adults, but no age-related differences were evinced when the task was completed alone. These findings suggest that, during adolescence, peers influence recruitment of reward-related regions even when they are engaged outside of the context of risk-taking. Implications for engagement in prosocial, as well as risky, behaviors during adolescence are discussed. Copyright © 2014 The Authors. Published by Elsevier Ltd.. All rights reserved.

The objective was to investigate how teachers' assessments of children predict life satisfaction in adolescence. This is a prospective cohort study on the population-based Northern Finland Birth Cohort 1986 (n = 8,959). Information was gathered from parents, teachers and adolescents using questionnaires at the age of 7, 8 and 15. Response rates were 80-90%. Emotional and behavioural problems were assessed with Rutter Children's Behavioural Questionnaires for teachers (RB2) and parents (RA2) during the first grade at age 8. At adolescence, self-reported life satisfaction was measured with a question including five response alternatives. According to teachers' assessments, 13.9% of the children had high emotional or behavioural problems (RB2 ≥9). These assessments predicted life dissatisfaction in adolescence (OR(crude) = 1.77; 95% CI 1.43-2.20) in several models including also health behaviour and use of psychotropic medicine. However, introducing all the significant variables in the same model, RB2 lost its significance (OR = 1.28; 0.96-1.70), but good school achievement assessed by teachers was still a significant predictor. Life satisfaction in adolescence was associated with a variety of favourable concurrent factors. In conclusion teachers' assessments of children during the first school year predicted life satisfaction in adolescence. In mental health promotion, teachers' early assessments should be utilized for the benefit of children.

This cross-sectional study assesses the association between age of sexual initiation during adolescence and a selection of well-being outcomes regarding that first relationship. High-school adolescents from El Salvador (2,686) and from Peru (3,399) replied to a paper-pencil questionnaire. Those who were sexually initiated replied to several questions regarding their age at sexual initiation, condom use, satisfaction and reasons/circumstances for that sexual relationship. Approximately 19% of participants were sexually initiated (n = 1,179). After retaining participants with valid responses and with sexual initiation ages between 13 and 17, the final sample for this paper consisted of 996 sexually initiated participants (526 Salvadorians and 470 Peruvians). Multiple logistic regression analyses showed that those who initiated sex at earlier ages had worse outcomes compared to those who initiated at older ages. Specifically, they had lower odds of having used a condom, of having good memories of that experience and of having had that first relationship because they were in love. Conversely, they had higher odds of having had that first sexual relationship as a result of peer pressure (“Most of my friends already had sex”), because of partner pressure (“I was afraid to lose him/her,” “My partner told me he/she would leave me” or “I did not know how to say no to a person who insisted”), or as a consequence of different forms of impaired autonomy (“I was under the influence of alcohol or drugs” or “As a consequence of seeing sexual images”). Results show that sex at earlier ages is associated with worse adolescent health and well-being outcomes. PMID:28798715

The minimum package of voluntary medical male circumcision (VMMC) services, as defined by the World Health Organization, includes human immunodeficiency virus (HIV) testing, HIV prevention counseling, screening/treatment for sexually transmitted infections, condom promotion, and the VMMC procedure. The current study aimed to assess whether adolescents received these key elements. Quantitative surveys were conducted among male adolescents aged 10-19 years (n = 1293) seeking VMMC in South Africa, Tanzania, and Zimbabwe. We used a summative index score of 8 self-reported binary items to measure receipt of important elements of the World Health Organization-recommended HIV minimum package and the US President's Emergency Plan for AIDS Relief VMMC recommendations. Counseling sessions were observed for a subset of adolescents (n = 44). To evaluate factors associated with counseling content, we used Poisson regression models with generalized estimating equations and robust variance estimation. Although counseling included VMMC benefits, little attention was paid to risks, including how to identify complications, what to do if they arise, and why avoiding sex and masturbation could prevent complications. Overall, older adolescents (aged 15-19 years) reported receiving more items in the recommended minimum package than younger adolescents (aged 10-14 years; adjusted β, 0.17; 95% confidence interval [CI], .12-.21; P < .001). Older adolescents were also more likely to report receiving HIV test education and promotion (42.7% vs 29.5%; adjusted prevalence ratio [aPR], 1.53; 95% CI, 1.16-2.02) and a condom demonstration with condoms to take home (16.8% vs 4.4%; aPR, 2.44; 95% CI, 1.30-4.58). No significant age differences appeared in reports of explanations of VMMC risks and benefits or uptake of HIV testing. These self-reported findings were confirmed during counseling observations.

Objective The validity of parent-reported adolescent vaccination histories has not been assessed. This study evaluated the validity of parent-reported adolescent vaccination histories by a combination of immunization card and recall, and by recall only, compared with medical provider records. Methods We analyzed data from the 2008 National Immunization Survey-Teen. Parents of adolescents aged 13–17 years reported their child's vaccination history either by immunization card and recall (n=3,661) or by recall only (n=12,822) for the hepatitis B (Hep B), measles-mumps-rubella (MMR), varicella (VAR), tetanus-diphtheria/tetanus-diphtheria-acellular pertussis (Td/Tdap), meningococcal conjugate (MCV4), and quadrivalent human papillomavirus (HPV4) (for girls only) vaccines. We validated parental report with medical records. Results Among the immunization card/recall group, vaccines with >20% false-positive reports included MMR (32.3%) and Td/Tdap (36.9%); vaccines with >20% false-negative reports included VAR (35.2%), MCV4 (36.0%), and Tdap (41.9%). Net bias ranged from −25.0 to −0.1 percentage points. Kappa values ranged from 0.22 to 0.92. Among the recall-only group, vaccines with >20% false-positive reports included Hep B (33.9%), MMR (61.4%), VAR (26.2%), and Td/Tdap (60.6%); vaccines with >20% false-negative reports included Hep B (58.9%), MMR (33.7%), VAR (51.6%), Td/Tdap (25.5%), Tdap (50.3%) MCV4 (63.0%), and HPV4 (20.5%). Net bias ranged from −46.0 to 0.5 percentage points. Kappa values ranged from 0.03 to 0.76. Conclusions Validity of parent-reported vaccination histories varies by type of report and vaccine. For recently recommended vaccines, false-negative rates were substantial and higher than false-positive rates, resulting in net underreporting of vaccination rates by both the immunization card/recall and recall-only groups. Provider validation of parent-reported vaccinations is needed for valid surveillance of adolescent vaccination coverage. PMID

Overweight among children and adolescents related to social inequality, as well as age and gender differences, may contribute to poor self-image, thereby raising important public health concerns. This study explores social inequality in relation to overweight and perception of overweight among 263 boys and girls, age 7 to 17, in Växjö, Sweden. Data were obtained through a questionnaire and from physical measurements of height, weight and waist circumference [WC]. To assess social, age and gender differences in relation to overweight, the independent sample t- and chi-square tests were used, while logistic regression modeling was used to study determinants for perception of overweight. Social inequality and gender differences as they relate to high ISO-BMI [Body Mass Index for children] and WC were associated with low maternal socioeconomic status [SES] among boys < 13 years [mean age = 10.4; n = 65] and with low paternal education level among boys ≥ 13 years [mean age = 15.0; n = 39] [p < 0.05]. One suggested explanation for this finding is maternal impact on boys during childhood and the influence of the father as a role model for adolescent boys. The only association found among girls was between high ISO-BMI in girls ≥ 13 years [mean age = 15.0; n = 74] and low paternal occupational status. Concerning perception of overweight, age and gender differences were found, but social inequality was not the case. Among boys and girls < 13 years, perception of overweight increased only when overweight was actually present according to BMI or WC [p < 0.01]. Girls ≥ 13 years [mean age = 15.0] were more likely to unrealistically perceive themselves as overweight or "too fat," despite factual measurements to the contrary, than boys [p < 0.05] and girls < 13 years [mean age = 10.4; n = 83] [p < 0.001]. The association between social inequality and overweight in adolescence in this study is age- and gender-specific. Gender differences, especially in perception of

Gender differences in play behavior and physical aggression have been consistently reported. Theoretical perspectives concerning evolutionary, social, and social-cognitive mechanisms suggest that male-typical play behavior during childhood increases subsequent physical aggression. The evidence supporting these connections is limited, however. The present study investigated the association between gender-typed play behavior in early childhood and physical aggression in early adolescence using a sample drawn from a longitudinal, population study, the Avon Longitudinal Study of Parents and Children. Based on gender-typed play behavior as measured by the Pre-School Activities Inventory at age 3.5 years, samples of masculine (64 boys, 60 girls), feminine (80 boys, 66 girls), and randomly selected control children (55 boys, 67 girls) were recruited at age 13 years and administered the Reinisch Aggression Inventory. After controlling for a range of sociodemographic variables, maternal characteristics, and behavioral problems, including hyperactivity and conduct problems at age 3.5, significant group differences in physical aggression at age 13 were found among children classified as masculine, control, and feminine at age 3.5. Masculine children exhibited significantly more physical aggression than control children or feminine children, and control children exhibited significantly more physical aggression than feminine children. The association between gender-typed play behavior and physical aggression was not moderated by sex. These results suggest that the degree of childhood gender-typed play behavior independently predicts the degree of physical aggression at adolescence in boys and in girls.

A previous report described a unique phenotype associated with an apparently de novo 732 kb 19q13.32 microdeletion, consisting of intellectual disability, facial asymmetry, ptosis, oculomotor abnormalities, orofacial clefts, cardiac defects, scoliosis and chronic constipation. We report three unrelated patients with developmental delay and dysmorphic features, who were all found to have interstitial 19q13.32 microdeletions of varying sizes. Both the previously reported patient and our Patient 1 with a larger, 1.3-Mb deletion have distinctive dysmorphic features and medical problems, allowing us to define a recognizable 19q13.32 microdeletion syndrome. Patient 1 was hypotonic and dysmorphic at birth, with aplasia of the posterior corpus callosum, bilateral ptosis, oculomotor paralysis, down-slanting palpebral fissures, facial asymmetry, submucosal cleft palate, micrognathia, wide-spaced nipples, right-sided aortic arch, hypospadias, bilateral inguinal hernias, double toenail of the left second toe, partial 2-3 toe syndactyly, kyphoscoliosis and colonic atony. Therefore, the common features of the 19q13.32 microdeletion syndrome include facial asymmetry, ptosis, oculomotor paralysis, orofacial clefting, micrognathia, kyphoscoliosis, aortic defects and colonic atony. These findings are probably related to a deletion of some combination of the 20-23 genes in common between these two patients, especially NPAS1, NAPA, ARHGAP35, SLC8A2, DHX34, MEIS3, and ZNF541. These candidate genes are expressed in the brain parenchyma, glia, heart, gastrointestinal tract and musculoskeletal system and likely play a fundamental role in the expression of this phenotype. This report delineates the phenotypic spectrum associated with the haploinsufficiency of genes found in 19q13.32. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

Measurements of height and weight provide important information on growth and development, puberty, and nutritional status in children and adolescents. The aim of this study was to develop contemporary reference growth centiles for Algerian children and adolescents (6-18 years of age). A cross-sectional growth survey was conducted in government schools on 7772 healthy schoolchildren (45.1% boys and 54.9% girls) aged 6-18 years in Constantine (eastern Algeria) in 2008. Height and weight were measured with portable stadiometers and calibrated scales, respectively. Smooth reference curves of height and weight were estimated with the LMS method. These height and weight curves are presented together with local data from Arab countries and with the growth references of France, Belgium (Flanders), and the World Health Organization (WHO) 2007. In girls, median height and weight increased until 16 and 17 years of age, respectively, whereas in boys, they increased through age 18 years. Between ages 11 and 13 years (puberty), girls were taller and heavier than boys. After puberty, boys became taller than girls, by up to 13 cm by the age of 18 years. Median height and weight of Algerian boys and girls were generally intermediate between those observed in other Arab countries. They were higher than the French reference values up to the age of 13 years and lower than Belgian and WHO reference values at all ages. The present study provides Algerian height- and weight-for-age growth charts, which should be recommended as a national reference for monitoring growth and development in children and adolescents.

Electronic cigarettes (e-cigarettes) are increasingly used by US adolescents and may be a gateway to traditional cigarette use. We examine rates of both products by age and examine differences in age-varying rates by sex and race/ethnicity. Data are from the 2014 National Youth Tobacco Survey, a national sample of US middle and high school students (n=22.007); students ages 11-19 were included. Past 30-day e-cigarette and traditional cigarette use were examined as a function of age; sex and race/ethnicity were included as moderators. The age-varying association between e-cigarette and traditional cigarette use was also examined. Rates of e-cigarette use increase faster than traditional cigarette use from ages 13-16. Compared to females, males had higher rates of e-cigarette use from ages 14-17.5 and traditional cigarette use from ages 15-18. Between ages 12-14, more Hispanic adolescents used e-cigarettes compared to White or Black adolescents; after age 14 Hispanics and Whites reported similar rates, peaking at twice the rate for Blacks. Hispanic adolescents report greater traditional cigarette use versus Whites between ages 12-13, but lower rates between ages 15-18. E-cigarette use was strongly associated with traditional cigarette use, particularly during early adolescence [OR>40 before age 12]. Young Hispanic adolescents are at elevated risk for use of e-cigarettes and traditional cigarettes during early adolescence. During early adolescence, youth using e-cigarettes are more likely to smoke traditional cigarettes compared to youth not using e-cigarettes. The study of age-varying effects holds promise for advancing understanding of disparities in health risk behaviors. Copyright © 2016 Elsevier Ltd. All rights reserved.

Pre- and post-Guidelines for Adolescent Preventive Services (GAPS) comparison of outcomes gathered via chart audit. A rural hospital-based general pediatric clinic. Adolescents who underwent annual examinations between April 1, 1998, and March 31, 2001. A random sample of 441 medical records was reviewed. Training in the GAPS model and use of the questionnaire began in April 1998. Detection of, discussion of, and referrals for GAPS-related risk behavior. The medical records of 162 younger adolescents (aged 11-15 years) and 279 older adolescents (aged 16-19 years) were audited. Detection of risk behaviors increased from 19% at baseline to 95% with the initial GAPS and 87% with the periodic GAPS. The most prevalent risk factor was having a rifle or gun in the home (younger adolescents, 47% and older adolescents, 39%). The mean number of risk behaviors and health concerns documented was higher in the initial GAPS (4.8 and 1.3, respectively) than in the periodic GAPS (3.8 and 0.7) (P =.01 and.006). The GAPS questionnaires detected lower levels of risk behavior compared with a local Youth Risk Behavior Survey. Controlling for sex, age, and clinician, discussion of psychosocial topics increased during the study period; however, there was considerable variation among clinicians regarding the topics addressed. The GAPS-related referral rate did not change significantly. The GAPS model increases clinicians' detection and discussion of risk behaviors.

2009-01-01

Context Most adults with a psychiatric disorder first met diagnostic criteria during childhood and/or adolescence, yet specific homotypic and heterotypic patterns of prediction have not been firmly established. Objective To establish which childhood and adolescent psychiatric disorders predict particular young adult disorders when accounting for comorbidities, disaggregating similar disorders, and examining childhood and adolescent predictors separately. Design/Setting/Patients Eleven waves of data from the prospective population-based Great Smoky Mountains Study (N = 1,420) were used, covering children in the community ages 9−16, 19, and 21 years old. Outcome Common psychiatric disorders were assessed in childhood (ages 9 to 12) and adolescence (ages 13 to 16) with the Child and Adolescent Psychiatric Assessment, and in young adulthood (ages 19 and 21) with the Young Adult Psychiatric Assessment. Results Adolescent depression significantly predicted young adult depression in the bivariate analysis, but this effect was entirely accounted for by comorbidity of adolescent depression with adolescent oppositional defiant disorder, anxiety and substance disorders in adjusted analyses. Generalized anxiety and depression cross-predicted each other, and oppositional defiant disorder (but not conduct disorder) predicted later anxiety disorders and depression. Evidence of homotypic prediction was supported for substance use disorders, antisocial personality disorder (from conduct disorder) and anxiety disorders, although this effect was primary accounted for by DSM-III-R overanxious disorder. Conclusions Stringent tests of homotypic and heterotypic prediction patterns suggest a more developmentally and diagnostically nuanced picture in comparison with the previous literature. The putative link between adolescent and young adult depression was not supported. Oppositional defiant disorder was singular in being part of the developmental history of a wide range of young adult

Objectives. To provide prevalence and trends of underweight, overweight, and obesity among reproductive-age women and adolescent girls in rural China. Methods. We measured weight and height in 16 742 344 women aged 20 to 49 years and 178 556 girls aged 15 to 19 years from the National Free Preconception Health Examination Project between 2010 and 2014. Results. Among women, the prevalence of underweight was 7.8% (95% confidence interval [CI] = 7.7%, 7.9%), and overweight or obesity was 16.5% (95% CI = 16.4%, 16.6%; World Health Organization criteria). Among adolescents, prevalence of underweight was 6.0% (95% CI = 5.7%, 6.2%; Centers for Disease Control and Prevention criteria) and overweight or obesity was 8.3% (95% CI = 7.9% to 8.8%; International Obesity Task Force criteria). According to Chinese criteria, overweight and obesity prevalence was 24.8% (95% CI = 24.7%, 24.9%) for women and 17.2% (95% CI = 16.6%, 17.8%) for adolescents, and underweight prevalence was 2.9% (95% CI = 2.8%, 3.1%) for adolescents. Considerable disparities existed in prevalence and trends within subpopulations (age groups, parity, region, education levels, and socioeconomic status). Conclusions. Our results reveal coexisting underweight and overweight or obesity among rural women and adolescents of reproductive age, which requires public health attention. PMID:27831775

Global prevalence of obesity has been increasing dramatically in all ages. Although traditional causes for obesity development have been studied widely, it is unclear whether environmental exposure of substances such as trace heavy metals affects obesity development among children and adolescents so far. Data from the National Health and Nutrition Examination Survey (1999-2011) were retrieved, and 6602 US children were analyzed in this study. Urinary level of nine trace heavy metals, including barium, cadmium, cobalt, cesium, molybdenum, lead, antimony, thallium, and tungsten, was analyzed for their association with the prevalence of obesity among children aged 6-19 years. Multiple logistic regression was performed to assess the associations adjusted for age, race/ethnicity, gender, urinary creatinine, PIR, serum cotinine, and television, video game, and computer usage. A remarkable association was found between barium exposure (OR 1.43; 95% CI 1.09-1.88; P < 0.001) and obesity in children aged 6-19 years. Negative association was observed between cadmium (OR 0.46; 95% CI 0.33-0.64; P < 0.001), cobalt (OR 0.56; 95% CI: 0.41-0.76; P < 0.001), and lead (OR 0.57; 95% CI 0.41-0.78; P = 0.018), and obesity. All the negative associations were stronger in the 6-12 years group than in the 13-19 years group. The present study demonstrated that barium might increase the occurrence of obesity, but cadmium, cobalt, and lead caused weight loss among children. The results imply that trace heavy metals may represent critical risk factors for the development of obesity, especially in the area that the state of metal contamination is serious.

Vulnerability to unhealthy behaviours across different age groups in Swedish Adolescents: a cross-sectional study

Paulsson Do, Ulrica; Edlund, Birgitta; Stenhammar, Christina; Westerling, Ragnar

2014-01-01

Purpose: There is lack of evidence on the effects of health-promoting programmes among adolescents. Health behaviour models and studies seldom compare the underlying factors of unhealthy behaviours between different adolescent age groups. The main objective of this study was to investigate factors including sociodemographic parameters that were associated with vulnerability to health-damaging behaviours and non-adoption of health-enhancing behaviours in different adolescent age groups. Methods: A survey was conducted among 10,590 pupils in the age groups of 13–14, 15–16 and 17–18 years. Structural equation modelling was performed to determine whether health-damaging behaviours (smoking and alcohol consumption) and non-adoption of health-enhancing behaviours (regular meal habits and physical activity) shared an underlying vulnerability. This method was also used to determine whether gender and socio-economic status were associated with an underlying vulnerability to unhealthy behaviours. Results: The findings gave rise to three models, which may reflect the underlying vulnerability to health-damaging behaviours and non-adoption of health-enhancing behaviours at different ages during adolescence. The four behaviours shared what was interpreted as an underlying vulnerability in the 15–16-year-old age group. In the youngest group, all behaviours except for non-participation in physical activity shared an underlying vulnerability. Similarly, alcohol consumption did not form part of the underlying vulnerability in the oldest group. Lower socio-economic status was associated with an underlying vulnerability in all the age groups; female gender was associated with vulnerability in the youngest adolescents and male gender among the oldest adolescents. Conclusions: These results suggest that intervention studies should investigate the benefits of health-promoting programmes designed to prevent health-damaging behaviours and promote health-enhancing behaviours in

Victimization, Suicidal Ideation, and Alcohol Use From Age 13 to 15 Years: Support for the Self-Medication Model

Purpose Recent years have seen increased coverage of adolescent victimization and suicide. Both adolescent peer victimization and substance use have been associated with suicidal ideation, with evidence suggesting that all three factors are interrelated. There are at least four models which can explain the associations between these factors (i.e., self-medication, secondary mental disorder, bidirectional, and common factor). However, none of them is being empirically supported as the dominant model because few longitudinal studies have explored the association between these factors. Methods The present study compared longitudinal paths of all four models simultaneously using a cross-lagged model. This was done using self-reported measures of peer victimization, suicidal ideation, and alcohol use at age 13, 14, and 15 years in a longitudinal sample of 238 adolescents. Results All three variables were moderately stable across time. Significant cross-lagged associations were found, showing that frequent peer victimization at age 13 years was associated with higher odds of having suicidal ideation at age 14 years (odds ratio, 1.82; p < .05). In turn, presence of suicidal ideation at age 14 years was significantly associated with higher alcohol use frequency at age 15 years (β = .13; p < .05). Conclusions Results support previous literature suggesting that peer victimization predates alcohol use and extends it by showing clear directionality between suicidal ideation and alcohol use over 1 year, supporting the self-medication model. Clarifying the empirical basis of these underlying models could allow for earlier prevention strategies, by targeting the risk factor that appears the earliest in the model. PMID:27914973

Adolescents' Experiences 7 and 13 Months Following the Death of a Brother or Sister.

Brooten, Dorothy; Youngblut, JoAnne M; Roche, Rosa M

2017-06-01

This qualitative study used semi-structured interviews to describe adolescents' responses at 7 and 13 months to siblings' NICU/PICU/ED death. At 7 months, adolescents were asked about events around the sibling's death; at 7 and 13 months, about concerns/fears, feelings, and life changes. Seventeen adolescents participated (13-18 years; M=15); 65% Black, 24% Hispanic, 11% White. Themes included death circumstances, burial events, thinking about the deceased sibling, fears, and life changes. Adolescents reported shock and disbelief that the sibling died; 80% knew the reason for the death; many had difficulty getting through burials; all thought about the sibling. From 7 - 13 months fears increased including losing someone and thoughts of dying. Adolescents reported more changes in family life and greater life changes in them (more considerate, mature) by 13 months; some felt friends abandoned them after the sibling's death. Girls had more fears and changes in family life and themselves. Adolescent's responses to sibling death may not be visually apparent. One recommendation from this study is to ask adolescents how they are doing separately from parents since adolescents may hide feelings to protect their parents, especially their mothers. Older adolescents (14-18 years) and girls may have more difficulty after sibling death.

Previous studies have indicated a link between speech-language and literacy development. To add to this body of knowledge, we investigated whether lexical and grammatical skills from toddler to early school age are related to reading competence in adolescence. Twenty-three typically developing children were followed from age 1;6 to 13;6 (years;months). Parental checklists and standardized tests were used to assess the development of mental lexicon, grammatical and reading capacities of the children. Direct assessment of early speech-language functions positively correlated with later reading competence, whereas lexical skills reported by parents were not associated with this capacity. At (pre-) school age, larger vocabulary and better grammatical abilities predicted advanced reading abilities in adolescence. Our study contributes to the understanding of typical speech-language development and its relation to later reading outcome, extending the body of knowledge on these developmental domains for future early identification of children at risk for reading difficulties.

Age-Specific Patient Navigation Preferences Among Adolescents and Young Adults with Cancer.

Patient navigation is increasingly being directed at adolescent and young adult (AYA) patients. This study provides a novel description of differences in AYA cancer patients' preferences for navigation services by developmental age at diagnosis. Eligible patients were diagnosed with cancer between ages 15 and 39 and had completed at least 1 month of treatment. Between October 2015 and January 2016, patients completed semi-structured interviews about navigation preferences. Summary statistics of demographic and cancer characteristics were generated. Differences in patient navigation preferences were examined through qualitative analyses by developmental age at diagnosis. AYAs were interviewed (adolescents 15-18 years N = 8; emerging adults 19-25 years N = 8; young adults 26-39 years N = 23). On average, participants were 4.5 years from diagnosis. All age groups were interested in face-to-face connection with a navigator and using multiple communication platforms (phone, text, email) to follow-up. Three of the most frequently cited needs were insurance, finances, and information. AYAs differed in support, healthcare, and resource preferences by developmental age; only adolescents preferred educational support. While all groups preferred financial and family support, the specific type of assistance (medical versus living expenses, partner/spouse, child, or parental assistance) varied by age group. AYAs with cancer have different preferences for patient navigation by developmental age at diagnosis. AYAs are not a one-size-fits-all population, and navigation programs can better assist AYAs when services are targeted to appropriate developmental ages. Future research should examine fertility and navigation preferences by time since diagnosis. While some navigation needs to span the AYA age range, other needs are specific to developmental age.

National data show a parallel relationship between recent trends in opioid prescribing practices and hospitalizations for opioid poisonings in adults. No similar estimates exist describing hospitalizations for opioid poisonings in children and adolescents. To describe the incidence and characteristics of hospitalizations attributed to opioid poisonings in children and adolescents. Retrospective analysis of serial cross-sectional data from a nationally representative sample of US pediatric hospital discharge records collected every 3 years from January 1, 1997, through December 31, 2012. The Kids' Inpatient Database was used to identify 13 052 discharge records for patients aged 1 to 19 years who were hospitalized for opioid poisonings. Data were analyzed within the collection time frame. Poisonings attributed to prescription opioids were identified by codes from the International Classification of Diseases, Ninth Revision, Clinical Modification. In adolescents aged 15 to 19 years, poisonings attributed to heroin were also identified. Census estimates were used to calculate incidence per 100 000 population. The Cochran-Armitage test for trend was used to assess for changes in incidence over time. From 1997 to 2012, a total of 13 052 (95% CI, 12 500-13 604) hospitalizations for prescription opioid poisonings were identified. The annual incidence of hospitalizations for opioid poisonings per 100 000 children aged 1 to 19 years rose from 1.40 (95% CI, 1.24-1.56) to 3.71 (95% CI, 3.44-3.98), an increase of 165% (P for trend, <.001). Among children 1 to 4 years of age, the incidence increased from 0.86 (95% CI, 0.60-1.12) to 2.62 (95% CI, 2.17-3.08), an increase of 205% (P for trend, <.001). For adolescents aged 15 to 19 years, the incidence increased from 3.69 (95% CI, 3.20-4.17) to 10.17 (95% CI, 9.48-10.85), an increase of 176% (P for trend, <.001). In this age group, poisonings from heroin increased from 0.96 (95% CI, 0.75-1.18) to 2.51 (95% CI, 2

Children differ from adults in the expression of dizziness symptoms and the causes of dizziness. In several studies, benign paroxysmal vertigo of childhood (BPVC) and vestibular migraine (VM) were seen exclusively in children with vertigo, but the age threshold used to define 'children' varies, and there are few reported studies about adolescents with dizziness. In this study, we investigated the prevalence of vestibular and balance disorders according to age category in a multi-center study (otolaryngology departments of 11 hospitals) of children and adolescents. Children and adolescents aged under 18 who visited the otolaryngology departments of 11 hospitals for dizziness were included. We classified the patients into three categories: preschool (up to and including 6-year-olds), school age (7- to 12-year-olds), and adolescents (13- to 18-year-olds). These patients were reviewed retrospectively based on their clinical charts. In the preschool age group, BPVC was most common, followed by VM. In the school-age group, BPVC and VMs were most common, followed by psychogenic vertigo and benign paroxysmal positional vertigo (BPPV). In adolescents, VM was the most common, and Ménière's disease, cardiogenic vertigo, and BPVC, which are seen primarily in adults, were also seen in some adolescents. In children and adolescents with dizziness, VM and BPVC were the most common diseases, and prevalence of disease by age showed differing distributions. These findings will help in diagnosing and managing children and adolescents with vertigo. Copyright © 2017 Elsevier B.V. All rights reserved.

Objective: To discuss the main causes and risk factors of disability and death among current Chinese adolescents. Methods: Subnational data of China from Global Burden of Disease Study 2015 (GBD 2015) was used to rank the causes and risk factors leading to death and disability adjusted life years (DALY) in Chinese adolescents aged between 10 and 19 years old, and thereby to analyze the main cauese and risk factors of death and DALY among Chinese adolescents in different genders. Results: In 2015, among Chinese adolescents aged 10-19 years old, the total DALY was 13 million 490 thousand years, and the total number of deaths was 63 258 cases. The top 3 causes of DALY were skin and subcutaneous diseases, iron-deficiency anemia and road injuries, resulting in DALY (constituent ratio) of 1 411 (10.5%), 1 094 (8.1%) and 1 029 (7.6%) thousand years respectively. The top 3 causes of death were road injuries, drowning and leukemia, causing 13 881 (21.9%), 9 895 (15.6%) and 4 620 (7.3%) deaths (constituent ratio) respectively. The top 3 risk factors of DALY were iron deficiency, alcohol use and drug use, causing 1 094 (8.1%), 487 (3.6%) and 220 thousand years (1.6%) DALY (constituent ratio) respectively. The top 3 risk factors of death were alcohol use, occupational injuries and drug use, causing 5 957 (9.4%), 1 523 (2.4%) and 810 (1.3%) deaths respectively. Conclusion: Unintentional injury was the top cause of DALY and death in Chinese adolescents, followed by skin and subcutaneous diseases and iron-deficiency anemia. Iron deficiency and alcohol use were the top two risk factors of DALY and death.

To investigate the age of onset of phobic disorders in relation to later development of substance dependence in a sample of adolescent psychiatric patients. Clinical sample of 238 adolescents (age 12-17) admitted to psychiatric inpatient hospitalization between April 2001 and July 2003. Psychiatric diagnoses and onset ages obtained from the schedule for affective disorders and schizophrenia for school aged children-present and lifetime (K-SADS-PL). Logistic regression analyses revealed that adolescents with phobic disorders had a 4.9-fold risk for comorbid substance dependence compared to those without phobia. The mean onset age was 11.4 and 14.4 years for phobias and comorbid substance dependence, respectively. Boys (13.7 years) had a statistically significantly lower onset age for substance dependence than girls (15.4 years). Over one-half of the adolescents with phobic disorders had developed substance dependence within three years after the onset of phobia. We found that phobias might influence the development of secondary substance dependence within a few years from the onset of phobia already in adolescence.

ABSTRACT OBJECTIVE To estimate the prevalence of illicit drug use and its association with binge drinking and sociodemographic factors among adolescent students. METHODS This is a cross-sectional study with probabilistic conglomerate sampling, involving 1,154 students, aged 13 to 19 years old, from the public school system, in the city of Olinda, State of Pernambuco, Brazil, carried out in 2014. We used the Youth Risk Behavior Survey questionnaire, validated for use with Brazilian adolescents. The Chi-square test (≤ 0.05) and Poisson regression analysis were used to estimate the prevalence ratios, with 95% confidence intervals. RESULTS Use in life of illicit drugs was four times more prevalent among students who reported binge drinking (95%CI 3.19–5.45). Being in the age group of 16 to 19 years, being male, and having no religion were also significantly associated with illicit drug use. CONCLUSIONS The prevalence of use in life of illicit drugs was higher in this study than in other studies carried out in Brazil and it was strongly associated with binge drinking. This factor was associated with gender, age, and religion. PMID:28876411

Subjective health complaints are common among adolescents. There is evidence that girls are more likely to register complaints than boys. This study examines gender differences in the relationship between daily smoking and recurrent subjective health complaints in school-aged adolescents in the USA. A cross-sectional design with a multistage probability sample was used to survey 13,339 middle and high school students (grades 6 through 10) with the US 2001-2002 Health Behavior in School-Aged Children Survey. Recurrent subjective health complaints were higher for adolescents who smoke daily and experiment with cigarettes than for those who never smoke. In logistic regression analyses, the odds of daily smoking increased twofold for both boys and girls who report recurrent irritability/bad temper. For girls, the odds of daily smoking were higher among those who reported recurrent headache, stomachache and backache compared with never smokers. For boys only recurrent backache and feeling dizzy were associated with increased odds of daily smoking. The relationship between recurrent subjective health complaints and daily smoking provides new insights into both conditions for school-aged adolescents. Findings from this study suggest different patterns of association between daily smoking and recurrent subjective health complaints occur for girls and boys. Further studies are needed to explore causes and treatment of daily smoking and recurrent health complaints among school-aged children. © 2010 Blackwell Publishing Ltd.

Living in the nuclear age: An Australian study of children's and adolescent's fears

DOE Office of Scientific and Technical Information (OSTI.GOV)

Slee, P.T.; Cross, D.G.

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

With psychopathology rising during adolescence and evidence suggesting that adult mental health burden is often due to disorders beginning in youth, it is important to investigate the epidemiology of adolescent mental disorders. We analysed data gathered at ages 11 (baseline) and 19 years from the population-based Dutch TRacking Adolescents' Individual Lives Survey (TRAILS) study. At baseline we administered the Achenbach measures (Child Behavior Checklist, Youth Self-Report) and at age 19 years the World Health Organization's Composite International Diagnostic Interview version 3.0 (CIDI 3.0) to 1584 youths. Lifetime, 12-month and 30-day prevalences of any CIDI-DSM-IV disorder were 45, 31 and 15%, respectively. Half were severe. Anxiety disorders were the most common but the least severe whereas mood and behaviour disorders were less prevalent but more severe. Disorders persisted, mostly by recurrence in mood disorders and chronicity in anxiety disorders. Median onset age varied substantially across disorders. Having one disorder increased subjects' risk of developing another disorder. We found substantial homotypic and heterotypic continuity. Baseline problems predicted the development of diagnosable disorders in adolescence. Non-intact families and low maternal education predicted externalizing disorders. Most morbidity concentrated in 5-10% of the sample, experiencing 34-55% of all severe lifetime disorders. At late adolescence, 22% of youths have experienced a severe episode and 23% only mild episodes. This psychopathology is rather persistent, mostly due to recurrence, showing both monotypic and heterotypic continuity, with family context affecting particularly externalizing disorders. High problem levels at age 11 years are modest precursors of incident adolescent disorders. The burden of mental illness concentrates in 5-10% of the adolescent population.

The present paper investigated gender differences on life satisfaction and self-esteem as well as the association between self-esteem and life satisfaction in Norwegian adolescents aged 13-18 years. The potential moderating role of gender and age in the relation between self-esteem and life satisfaction was also investigated. A total of 1,239 adolescents from public elementary and secondary schools in mid-Norway participated in the school-based survey study. Mean score differences on the variables used in the study were tested using t tests. Hierarchical multiple regression analysis was used to evaluate the association between self-esteem and life satisfaction, controlled for gender, age, stress, subjective health, and chronic health conditions. The results showed that boys scored higher than girls on both self-esteem and life satisfaction. Self-esteem was positively associated with life satisfaction, explaining 24 % of the variance. However, no interaction effect of gender × self-esteem or age × self-esteem was found in relation to life satisfaction. The results give support for that boys report higher self-esteem and life satisfaction than girls. Self-esteem has a positive role in association with adolescents' life satisfaction, and this relationship is equally strong for both genders and across age.

To test whether sleep duration on school nights differs between adolescents in Australia and the United States and, if so, whether this difference is explained by cultural differences in school start time, parental involvement in setting bedtimes, and extracurricular commitments. Three hundred eighty-five adolescents aged 13 to 18 years (M = 15.57, SD = 0.95; 60% male) from Australia and 302 adolescents aged 13 to 19 years (M = 16.03, SD = 1.19; 35% male) from the United States. Adolescents completed the School Sleep Habits Survey during class time, followed by an 8-day sleep diary. After controlling for age and gender, Australian adolescents obtained an average of 47 minutes more sleep per school night than those in the United States. Australian adolescents were more likely to have a parent-set bedtime (17.5% vs. 6.8%), have a later school start time (8:32 a.m. vs. 7:45 a.m.), and spend less time per day on extracurricular commitments (1 h 37 min vs. 2 h 41 min) than their U.S. peers. The mediating factors of parent-set bedtimes, later school start times, and less time spent on extracurricular activities were significantly associated with more total sleep. In addition to biological factors, extrinsic cultural factors significantly affect adolescent sleep. The present study highlights the importance of a cross-cultural, ecological approach and the impact of early school start times, lack of parental limit setting around bedtimes, and extracurricular load in limiting adolescent sleep.

We present three patients with overlapping interstitial deletions of 19p13.3 identified by high resolution SNP microarray analysis. All three had a similar phenotype characterized by intellectual disability or developmental delay, structural heart abnormalities, large head relative to height and weight or macrocephaly, and minor facial anomalies. Deletion sizes ranged from 792 Kb to 1.0 Mb and included a common region arr [hg19] 19p13.3 (3,814,392-4,136,989), containing eight genes: ZFR2, ATCAY, NMRK2, DAPK3, EEF2, PIAS4, ZBTB7A, MAP2K2, and two non-coding RNA's MIR637 and SNORDU37. The patient phenotypes were compared with three previous single patient reports with similar interstitial 19p13.3 deletions and six additional patients from the DECIPHER and ISCA databases to determine if a common haploinsufficient phenotype for the region can be established.

2006-07-01

To evaluate the factors associated with depressive symptoms in a sample of Nigerian 13-18-year-olds attending senior secondary schools. Adolescents aged 13 to 18 years (n = 1095) attending senior secondary schools completed the Beck Depressive Inventory (BDI) as a measure of their depressive symptoms. The adolescents and their parents also completed various questionnaires regarding related demographic, psychosocial and family factors. There were 99 (9.0%) adolescents with clinically significant depressive symptoms. The factors significantly associated with adolescents' depressive symptoms include parental depressive symptoms (odds ratio [OR] 5.21, 95% confidence interval [CI] 3.48-7.81), adolescents' perception of family functioning as poor (OR 6.79, 95% CI 3.46-12.23), adolescents' problems with peers (OR 4.69, 95% CI 3.06-7.19), adolescents' low self-esteem (OR 6.63, 95% CI 2.59-16.96), adolescents' drinking (OR 3.98, 95% CI 2.37-6.69), female gender (OR 1.74, 95% CI 1.11-2.72), and large family size (OR 2.83, 95% CI 1.15-7.74). Child and adolescent health policy-makers should consider these factors when planning healthcare services or formulating a predictive model for adolescents' depression in low-income countries. Clinical assessment should focus on identification of these variables and nonpharmacological interventions may be of relevance in addressing some of the associated factors.

India is home to the highest number of adolescents in the world. Adolescents in India suffer from lack of knowledge and empowerment to make informed sexual and reproductive health decisions. This paper analyses the prevalence of reproductive tract infections and sexually transmitted infections (RTI/STI) and treatment seeking behavior among married adolescent women in India aged 15-19 years. Data from the District Level Household Survey (DLHS, 2007-08) of India were used. The prevalence of RTIs symptoms and treatment seeking behavior among women by different socio-demographic characteristics was analyzed. Factor analysis was utilized to create an index using information about 11 symptoms of RTI/STI collected in the survey. Linear and binary logistic regressions were used to know the association between infections and treatment seeking behavior with socio-demographic factors. About 15 percent of adolescent women reported having any symptoms of RTI/STI. The main symptoms reported were low backache, pain in the lower abdomen, pain during intercourse and itching or irritation around the vulvar region. Factor analysis showed the concentration of diseases in three clusters - infection in around the vulva, other reproductive infection and abnormal discharge; and intercourse related problems. Major predictors of both symptoms of reproductive infections and treatment seeking behavior from multivariate analysis are age, education, wealth, region and awareness about RTI/STI. Knowledge and treatment seeking behavior is poor among adolescent women in India. There is need for programmatic and policy emphasis on increasing knowledge and awareness through family life education including in educational curriculum at school level.

We evaluated the associations of teenage insulin and adolescent diet with 10-year weight gain in an analysis sample of black and white girls matched for pubertal stage, body mass index (BMI) (or fat mass), and insulin at ages 9 to 10 years. We hypothesized that preteen insulin and insulin resistance would interact with dietary factors to positively predict increases in BMI. Furthermore, we hypothesized that increased insulin and insulin resistance, interacting with higher caloric intake during adolescence, would lead to greater increments in BMI in black girls than in white girls. Prospective 10-year follow-up was performed on 215 pairs of black and white schoolgirls matched at baseline by BMI (or fat mass), insulin, and pubertal stage, with repeated measures of body habitus, insulin, and dietary intake. When matched for BMI, black girls had higher fat-free mass and white girls had higher fat mass at ages 9 to 10 years. Black-white differences in caloric intake were not significant at ages 9 to 10 years, but black girls consumed more calories at age 19 years. Black girls consumed a greater percentage of calories from fat throughout. At age 19 years, black girls had higher BMI, fat mass index, and insulin. When matched at ages 9 to 10 years for fat mass, black girls were heavier, had higher BMI, and had greater fat-free mass. By ages 18 to 19 years, black girls continued to have higher BMI, but had accrued higher fat mass and a higher percentage of body fat. By stepwise multiple regression, 10-year increases in BMI were predicted by ages 9 to 10 years BMI, 10-year change in insulin, and a 3-way interaction between ages 9 to 10 years insulin, adolescent caloric intake, and race (higher in black girls) (all Ps < .0001). Insulin at ages 9 to 10 years interacts with caloric intake to increase BMI by age 19 years. There appear to be intrinsic black-white metabolic differences that lead to greater gains in fat during adolescence in black girls. Evaluating BMI and insulin

As adolescent pregnancy and sexually transmitted infections (STIs) are major sources of morbidity, preventing them is an important health goal for Portuguese society. To review data on the knowledge, attitudes and statistics on sexual and reproductive health. A systematic review was conducted including peer-reviewed articles addressing issues influencing the sexuality of Portuguese adolescents (aged 13 to 19), published up to 2011 and conducted in any type of setting. After crossing-cleaning the reference list, 33 articles were included. The rate of sexual activity by Portuguese adolescents is high (44%-95%), but there has been an increase in the age of intercourse debut (currently 15.6 years). Early commencement of sexual intercourse is associated with smoking and regular alcohol consumption. Condoms are the most frequently chosen contraceptive method for first (76%-96%) and subsequent (52%-69%) sexual encounters. The perception of a double standard in sex still exists in teenage culture for both genders and influence behavior. There are significant differences between migrant and native adolescents: African adolescents initiate sexual intercourse at earlier ages and are more likely to have unprotected sex. Only one-third of Portuguese teenagers have ever visited a health facility to seek counseling concerning contraception or STIs, and less than half have ever attended classes on reproductive health. Very few (12%) have knowledge about Chlamydia trachomatis infection. The prevalence of STIs in Portuguese youth is unknown. The adolescent fertility rate is still high (14.7 births per 1000 females aged 15-19 years), but it, as well as the rate of abortion, is steadily decreasing. There is still a long way to go towards promoting a resourceful young population. Citizens and institutions must focus on increasing both the competence of youths and external supports. Information must be provided systematically and health services must have greater accessibility. Studies

To determine decision limits for total cholesterol, LDL-cholesterol, non-HDL cholesterol, HDL-cholesterol, and triglycerides in healthy children and adolescents from Cuiabá, Brazil. This was a cross-sectional study of 1866 healthy children and adolescents randomly selected from daycare centers and public schools in Cuiabá. The desirable levels of serum lipids were defined using the classic criteria, i.e., total cholesterol, LDL-cholesterol, non-HDL cholesterol, and triglycerides levels below the P75 percentile, and HDL-c above the P10 percentile. For CT, P75 was: 160mg/dL for the age range of 1 to <3 years, 170mg/dL for ≥3 to <9 years, and 176mg/dL for ≥9 to <13 years. For non-HDL cholesterol, it was 122mg/dL for the age range of 1 to <13 years. For LDL-c, it was 104mg/dL at the age range of 1 to <9 years and 106mg/dL from ≥9 to <13 years. For TG, it was 127mg/dL from 1 to <2 years; 98mg/dL from ≥2 to <6 years; and 92mg/dL from ≥6 to <13 years. As for HDL-cholesterol, P10 was 24mg/dL, 28mg/dL, 32mg/dL, and 36mg/dL, for the age ranges of 1 to <2 years, ≥2 to <3 years, ≥3 to <4 years, and ≥4 to <13 years, respectively. The decision limits for the serum lipid levels defined in this study differed from those observed in the current Brazilian and North-American guidelines, especially because it differentiates between the age ranges. Using these decision limits in clinical practice will certainly contribute to improve the diagnostic accuracy for dyslipidemia in this population group.

An evidence-based HIV prevention intervention was adapted for Botswana youth with qualitative interviews, input from an adolescent panel, and social validation. Qualitative interviews were conducted with 40 boys and girls ages 13-19. An adolescent panel then drafted scenarios reflecting social situations described in the interviews that posed risk for HIV. A social validation sample (N = 65) then indicated the prevalence and difficulty of each situation. Youth described informational needs, pressures to use alcohol and drugs, peer pressure for unprotected sex, and intergenerational sex initiations as risk-priming situations. From 17% to 57% of the social validation sample had personally experienced the situations drafted by the adolescent panel. There were no differences in the ratings of boys versus girls, but youth over age 16 more often reported that they had experienced these risky situations. The results were embedded into the intervention. Major changes to the intervention resulted from this three-phase process.

Although pregnant adolescents are at high risk of poor birth outcomes, the majority of adolescents go on to have full-term, healthy babies. Data from the National Longitudinal Study of Adolescent Health, a longitudinal study of a nationally representative sample of adolescents in grades 7–12 in the United States who were surveyed from 1994–1995 through 2008, were used to examine the epidemiology of preterm birth and low birth weight within this population. Outcomes of pregnancies were reported by participants in the fourth wave of data collection (when participants were 24–32 years of age); data were compared between female participants who reported a first singleton livebirth at less than 20 years of age (n = 1,101) and those who were 20 years of age or older (n = 2,846). Multivariable modeling was used to model outcomes; predictors included demographic characteristics and maternal health and behavior. Among black adolescents, low parental educational levels and older age at pregnancy were associated with higher birth weight, whereas low parental educational levels and being on birth control when one got pregnant were associated with higher gestational age. In nonblack adolescents, lower body mass index was associated with lower birth weight, whereas being unmarried was associated with lower gestational age. Predictors of birth outcomes may differ by age group and social context. PMID:23035139

Unhealthy dietary pattern increases the risk of obesity and metabolic disorders in growing children and adolescents. However, the way the habitual pattern of breakfast consumption influences body composition and risk of obesity in adolescents is not well defined. Thus, the aim of the present study was to assess any associations between breakfast consumption practices and body composition profiles in 236 apparently healthy adolescents aged 12 to 19 years. A self-administered questionnaire on dietary behaviour and lifestyle practices and a dietary food frequency questionnaire were used. Body composition and adiposity indices were determined using standard anthropometric measurement protocols and dual energy χ-ray absorptiometry (DXA). Mean age of the participants was 15.3±1.9 years. The majority of participants (71.2%) fell in the normal body mass index (BMI) ranges. Breakfast consumption patterns showed that only half of the participants (50%) were consuming breakfast daily. Gender-specific multivariate analyses (ANCOVA) showed that in both boys and girls, those eating breakfast at least 5 times a week had significantly lower body weight, body mass index (BMI), BMI z-scores, waist circumference, body fat mass and percent body fat (%BF) compared to infrequent breakfast eaters, after adjustment for age, household income, pubertal status, eating-out and snacking practices, daily energy intakes, and daily physical activity levels. The present findings indicate that infrequent breakfast consumption is associated with higher body adiposity and abdominal obesity. Therefore, daily breakfast consumption with healthy food choices should be encouraged in growing children and adolescents to prevent adiposity during these critical years of growth.

Prader-Willi syndrome (PWS) is a complex, multisystem genetic disorder characterized by endocrine, neurologic, and behavioral abnormalities. We report the first case of an unbalanced de novo reciprocal translocation of chromosomes 15 and 19, 45,XY,-15,der(19)t(15;19)(q12;p13.3), resulting in monosomy for the PWS critical chromosome region. Our patient had several typical features of PWS including infantile hypotonia, a poor suck and feeding difficulties, tantrums, skin picking, compulsions, small hands and feet, and food seeking, but not hypopigmentation, a micropenis, cryptorchidism or obesity as common findings seen in PWS at the time of examination at 6 years of age. He had seizures noted from 1 to 3 years of age and marked cognitive delay. High-resolution SNP microarray analysis identified an atypical PWS type I deletion in chromosome 15 involving the proximal breakpoint BP1. The deletion extended beyond the GABRB3 gene but was proximal to the usual distal breakpoint (BP3) within the 15q11q13 region, and GABRA5, GABRG3, and OCA2 genes were intact. No deletion of band 19p13.3 was detected; therefore, the patient was not at an increased risk of tumors from the Peutz-Jeghers syndrome associated with a deletion of the STK11 gene. © 2016 S.

Studies have linked adolescent alcohol use with adverse consequences in adulthood; yet it is unclear how strong the associations are and to what extent they may be due to confounding. Our aim was to estimate the strength of association between different patterns of adolescent drinking and longer-term psychosocial harms taking into account individual, family, and peer factors. Participant-level data were integrated from four long running longitudinal studies: Australian Temperament Project; Christchurch Health and Development Study; Mater Hospital and University of Queensland Study of Pregnancy; Victorian Adolescent Health Cohort Study. Australia and New Zealand. Participants were assessed on multiple occasions between ages 13 and 30 years (from 1991-2012). Number of participants varied (up to N=9453) by analysis. Three patterns of alcohol use (frequent, heavy episodic, and problem drinking) were assessed prior to age 17. Thirty outcomes were assessed to age 30 spanning substance use and related problems, antisocial behavior, sexual risk-taking, accidents, socioeconomic functioning, mental health, and partner relationships. After covariate adjustment, weekly drinking prior to age 17 was associated with a two to three-fold increase in the odds of binge drinking (OR: 2.14; 95%CI: 1.57-2.90), drink driving (OR: 2.78; 95%CI: 1.84-4.19), alcohol-related problems (OR: 3.04; 95%CI: 1.90-4.84), and alcohol dependence (OR: 3.30; 95%CI: 1.69-6.47) in adulthood. Frequency of drinking accounted for a greater proportion of the rate of most adverse outcomes than the other measures of alcohol use. Associations between frequent, heavy episodic, and problem drinking in adolescence and most non-alcohol outcomes were largely explained by shared risk factors for adolescent alcohol use and poor psychosocial functioning. Frequency of adolescent drinking predicts substance use problems in adulthood as much as, and possibly more than, heavy episodic and problem drinking independent of

Objectives. We examined sexual orientation differences in adolescent smoking and intersections with race/ethnicity, gender, and age. Methods. We pooled Youth Risk Behavior Survey data collected in 2005 and 2007 from 14 jurisdictions; the analytic sample comprised observations from 13 of those jurisdictions (n = 64 397). We compared smoking behaviors of sexual minorities and heterosexuals on 2 dimensions of sexual orientation: identity (heterosexual, gay–lesbian, bisexual, unsure) and gender of lifetime sexual partners (only opposite sex, only same sex, or both sexes). Multivariable regressions examined whether race/ethnicity, gender, and age modified sexual orientation differences in smoking. Results. Sexual minorities smoked more than heterosexuals. Disparities varied by sexual orientation dimension: they were larger when we compared adolescents by identity rather than gender of sexual partners. In some instances race/ethnicity, gender, and age modified smoking disparities: Black lesbians–gays, Asian American and Pacific Islander lesbians–gays and bisexuals, younger bisexuals, and bisexual girls had greater risk. Conclusions. Sexual orientation, race/ethnicity, gender, and age should be considered in research and practice to better understand and reduce disparities in adolescent smoking. PMID:24825218

Tobacco use during adolescence is a substantial problem and adolescents are at higher risk of addiction and prolonged use. To reduce the burden of tobacco-related morbidity and mortality, monitoring of adolescent tobacco use is imperative. We aimed to determine the prevalence of tobacco use among adolescents in urban and rural secondary schools in Enugu State, southeast Nigeria. A cross-sectional study of 4332 adolescents in 8th to 10th grades in 25 urban and 24 rural secondary schools in Enugu, Nigeria was done using Global Youth Tobacco Survey (GYTS) methodology. Students were asked about previous and current tobacco use, smoking cessation, and susceptibility to smoking initiation among non-smokers. Geographical, age and sex prevalence differences were examined. Analyses were performed for all adolescents (10-19 years) and for a subset of students, 13-15 years of age for comparison with previous GYTS surveys. All analyses were weighted to account for the complex survey design and for differential non-response at school, class and student levels. About 28.9% of students reported ever smoking cigarettes; 19.4% reported current tobacco use among all adolescents (13.3, 5.8 and 7.8% for cigarettes, other smoked tobacco, and smokeless tobacco, respectively) while 18.6% reported current tobacco use among 13-15 year olds (12.6, 5.2 and 7.5% for cigarettes, other smoked tobacco and smokeless tobacco respectively). Prevalence of all types of tobacco use was higher in rural schools (vs. urban schools), and among boys (vs. girls). Susceptibility to smoking initiation among non-smokers was 9.3% (95% CI: 8.1-10.7) among all adolescents, and 9% (95% CI: 7.6-10.7) among 13-15 year olds. About 88.1% of all adolescent smokers desired to quit and 57.9% of them had never received help to quit smoking. Nearly one in every five school-going adolescents currently uses at least one type of tobacco in Enugu State, southeast Nigeria. Prevalence of tobacco use is higher in rural

To investigate total leisure noise exposure among adolescents and to assess its association with hearing. Based on self-reported time spent on 19 leisure activities and associated mean sound pressure levels reported in the literature, total leisure noise exposure was evaluated and compared to noise at work limits (> 85 dB(A) = hazardous) in a cross-sectional survey. Tympanometry and pure-tone audiometry was performed in sound isolated rooms. The study sample consists of 2143 pupils attending grade nine in any school in a German city 2009-2011 (mean age: 15.4 years; range: 13-19 years). Audiometric data were available for 1837 (85.8%) pupils (53.9% girls). 41.9% of the 2143 adolescents who had provided self-reported data on leisure activities associated with noise exposure were estimated to be hazardously exposed to leisure time noise. The interaction of gender with total leisure time noise exposure was not significant. No association between leisure time noise exposure and audiometric notches could be detected. While hearing loss seems seldom in this age group, a high proportion of adolescents aged 15-16 years are exposed to noise levels during leisure time bearing long-term risks of hearing loss.

Women have higher rates of auditory verbal hallucinations (AVH) than men; however, less is known about sex differences in the prevalence of AVH in early, middle and late adolescence. We sought to elucidate the differences in the prevalence of AVH and to examine the degree to which these differences could be explained by differences in levels of depressive symptoms. We used a cross-sectional design and a self-reported questionnaire. Participants were recruited from public junior and senior high schools in Tsu, Mie Prefecture and Kochi Prefecture, Japan. In total, 19 436 students were contacted and 18 250 participated. Responses from 17 451 students with no missing data were analysed (aged 12-18 years, M age =15.2 years (SD=1.7), 50.6% girls). AVH were assessed through one of four items adopted from the schizophrenia section of the Japanese version of the Diagnostic Interview Schedule for Children. Depressive symptoms were assessed using the 12-item General Health Questionnaire. The prevalence of AVH was 7.0% among early adolescents (aged 12-13 years), 6.2% among middle adolescents (aged 14-15 years) and 4.8% among late adolescents (aged 16-18 years). Being female was significantly associated with a higher prevalence of AVH through adolescence (OR=1.71, 95% CI 1.31 to 2.23 in early adolescence; OR=1.42, 95% CI 1.14 to 1.76 in middle adolescence; OR=1.52, 95% CI 1.23 to 1.87 in late adolescence); however, these differences became non-significant after adjusting for depressive symptoms (OR=1.21, 95% CI 0.92 to 1.60; OR=1.00, 95% CI 0.80 to 1.25; OR=1.16, 95% CI 0.93 to 1.44, respectively). Sex differences in auditory hallucinations are seen in both adult and youth populations. The higher rates of auditory verbal hallucinations seen in girls may be secondary to the differences in the rate of depressive symptoms. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Research on the relationships between adolescent and parental disordered eating (DE) and emotion dysregulation is scarce. Thus, the aim of this study was to explore whether mothers' and fathers' own DE, as measured by SCOFF questionnaire, and emotion dysregulation, as measured by the difficulties in emotion regulation scale (DERS), were associated with their daughters' or sons' DE and emotion dysregulation. Furthermore, the importance of shared family meals and possible parent-related predictors of adolescent DE were explored. The total sample comprised 1,265 adolescents (M age  = 16.19, SD = 1.21; age range 13.5-19 years, 54.5% female) whose parents had received a self-report questionnaire via mail. Of these, 235 adolescents (18.6% of the total sample) whose parents completed the questionnaire were used in the analyses. Parents' responses were matched and compared with those of their child. Adolescent girls showed greater levels of DE overall than did their parents. Furthermore, DE was associated with emotion dysregulation among both adolescents and parents. Adolescent and parental emotion dysregulation was associated, although there were gender differences in the specifics of this relationship. The frequency of shared dinner meals was the only variable that was associated to DE and emotion dysregulation among adolescents, while parental eating disorder was the only variable that enhanced the probability of adolescent DE. The present study contributes to the literature by demonstrating that there are significant associations between parents and their adolescent children in terms of DE, emotion dysregulation, and shared family meals. Future studies should break down these relationships among mothers, fathers, girls, and boys to further clarify the specific associational, and possibly predictive, directions.

The use of melatonin is increasing among Swedish children and adolescents despite deficient knowledge of usage in these groups. The aim of this study was to investigate the use of melatonin in Swedish children and adolescents according to age, gender, dosage, treatment duration, and use of attention deficit hyperactivity disorder (ADHD) medication. Data from the Swedish Prescribed Drug Register was analyzed for children and adolescents 0-19 years old in Sweden during 2006-2013. The number of new users of melatonin in 2013 was 4296 and 3093 among boys and girls, respectively. Girls started treatment with melatonin in older ages compared to boys. Regular users of melatonin were most common among boys 10-14 years. The average defined daily dose (DDD) per regular user was decreasing from 2.4 DDD in 2006 to 1.7 DDD in 2012. Among girls and boys 5-9 years who were regular users in 2010, over 40 and 50%, respectively, were still regular users in 2013. In the age group 15-19 years, only about 10% were still regular users in 2013. In 2013, 65% of boys and 49% of girls, using melatonin regularly, also used medication for ADHD regularly. More Swedish boys than girls used melatonin regularly. The boys started treatment earlier and more often combined regular use of melatonin with regular use of medication for ADHD. This indicates that girls and boys partly are prescribed melatonin for different reasons. About half of the younger children stayed on melatonin treatment for several years, while 90% of adolescents (15-19 years) concluded their treatment.

Sleep Instabilities Assessed by Cardiopulmonary Coupling Analysis Increase During Childhood and Adolescence.

Cysarz, Dirk; Linhard, Maijana; Seifert, Georg; Edelhäuser, Friedrich

2018-01-01

The electrocardiogram-based cardiopulmonary coupling (CPC) technique may be used to track sleep instabilities. With progressing age, maturational changes during childhood and adolescence affect sleep. The objective was to assess developmental changes in sleep instabilities in a natural setting. ECGs during nighttime sleep on regular school days were recorded from 363 subjects aged 4 to 22 years (204 females). The estimated total sleep time (ETST) decreased from 598 to 445 min during childhood and adolescence. Stable sleep linearly decreased with progressing age (high frequency coupling (HFC): 70-48% ETST). Unstable sleep [low frequency coupling (LFC): 9-19% ETST], sleep fragmentation or disordered breathing (elevated LFC: 4-12% ETST), and wake/REM states [very low frequency coupling (VLFC): 20-32% ETST] linearly increased with age. Hence, with progressing age the sleep of children and adolescents shortens, becomes more unstable and is more often affected by fragmentation or sleep disordered breathing, especially in the age group >13 years. It remains to be clarified whether some of the changes are caused by a social jetlag, i.e., the misalignment of body clock and social time especially in adolescents.

The association between asthma and pregnancy has been documented previously. The relationship between unplanned pregnancy and onset asthma in adolescence has not been studied. To determine the association between unplanned pregnancy and adolescence onset asthma. A cross-sectional study was done gathering information about asthma, unplanned pregnancy, family atopy and active or passive smoking in 3,130 adolescents aged 13-19 years. Asthma diagnosis was established through a selfquestionnaire based on the International Study of Asthma and Allergy in Childhood. Odds ratios for asthma were determined using logistic regression model and chi-squared test. Mean age of the participants was 16.37 ± 1.93 years. The prevalence of active smoking was 16.1%, of passive smoking 40% and of family atopy 9.8%. From the pregnant adolescents (785), 59.5% reported had planned not to have a child before pregnancy. Prevalence of wheezing during the year prior to the study was 9.3% and of wheezing during the pregnancy 2%. The prevalence of adolescence onset asthma was 5.4%. The age of initiation of asthma in the adolescence was 14.75 ± 1.60 years. The analysis showed that unplanned pregnancy has a slight risk for the development of asthma during adolescence. (Crude OR=1.03; CI 95% 1.02-1.05; p=0.000). Unplanned pregnancy, family atopy, active smoking and smoking friends are associated with the onset-asthma in the adolescence.

This article examines the health implications of new age technology use among adolescents. As Internet prevalence has increased, researchers have found evidence of potential negative health consequences on adolescents. Internet addiction has become a serious issue. Pornography is now easily accessible to youth and studies have related pornography with several negative health effects. Cyberbullying has become a large problem as new age technologies have created a new and easy outlet for adolescents to bully one another. These technologies are related to increased morbidity and mortality, such as suicides due to cyberbullying and motor vehicle deaths due to texting while driving. Copyright © 2016 Elsevier Inc.

To determine hemoglobin levels and anemia in pregnant adolescents who attended the health care facilities of the Ministry of Health of Peru between the years 2009 and 2012. Cross-sectional study of secondary data analysis using the Information System of the Nutritional Status of Children and Pregnant Women (SIEN). 265,788 records of pregnant women aged 10 to 19 years were reviewed. Hemoglobin levels (g/dL) and the percentage of anemia in the first, second and third trimesters were measured. Descriptive statistics with confidence intervals at 95% were applied. 3.4% of pregnant women were aged 10 to 14 years (early adolescence), 21.6% between 15 to 16 years (middle adolescence) and 75% between 17 to 19 years (late adolescence). Hemoglobin levels in pregnant adolescents were 11.6 ± 1.3 g/dL in 2009 and 11.5 ± 1.3 g/dL during the years 2010, 2011 and 2012. The overall incidence of anemia for 2009 was 25.1% (95% CI 24.4-25.8); for 2010 was 26.0% (95% CI 25.3-26.6) for 2011 was 26.4% (95% CI 25.8-27.1) and 25.2% for 2012 (95% CI 24.6-25.9). Hemoglobin levels were on average lower for pregnant residents in high Andean areas. About a quarter of pregnant adolescents in our sample had anemia.

Alcohol advertising in magazines and adolescent readership.

Garfield, Craig F; Chung, Paul J; Rathouz, Paul J

2003-05-14

Adolescent drinking is a major public health concern. The federal government does not restrict alcohol advertising to adolescents, but relies on the alcohol industry for self-regulation. To investigate recent alcohol advertising in magazines and to determine whether advertising frequency is associated with adolescent readership. All alcohol advertisements were counted that appeared from 1997-2001 in 35 of 48 major US magazines, which tracked their adolescent readership (3 refused all alcohol advertisements; and advertisement counts were unavailable for 10). Variation was assessed in the advertisement placement frequency for each major category of alcohol (beer, wine and wine coolers, and distilled liquor) by a magazine's adolescent readership (age 12-19 years), young adult readership (age 20-24 years), and older adult readership (age > or =25 years); readership demographics (sex, race, and income); year; frequency of publication; and cost per advertisement. Variation in alcohol advertising frequency by adolescent readership. Adolescent readership ranged from 1.0 to 7.1 million. The alcohol industry placed 9148 advertisements at a cost of 696 million dollars. Of the 9148 advertisements, 1201 (13%) were for beer, 443 (5%) for wine, and 7504 (82%) for liquor. After adjustment for other magazine characteristics, the advertisement rate ratio was 1.6 times more for beer (95% confidence interval [CI], 1.0-2.6; P =.05) and liquor (95% CI, 1.1-2.3; P =.01) for every additional million adolescent readers. Wine industry advertising was not associated with adolescent readership. Magazine advertising by the beer and liquor industries is associated with adolescent readership. Industry and federal policymakers should examine ways to regulate advertising that reaches large numbers of adolescents.

Background Sugar-sweetened beverages (SSBs) have been associated with obesity in children and adults; however, associations between beverage patterns and obesity are not understood. Objective To describe beverage patterns during adolescence, and the associations between adolescent beverage patterns and age 17 anthropometric measures. Design Cross-sectional analyses of longitudinally-collected data. Participants/setting Participants in the longitudinal Iowa Fluoride Study having at least one beverage questionnaire completed between ages 13.0 and 14.0 years, having a second questionnaire completed between 16.0 and 17.0 years and attending an age 17 clinic exam for weight and height measurements (n=369). Exposure Beverages were collapsed into 4 categories {i.e., 100% juice, milk, water and other sugar-free beverages (water/SFB), and SSBs} for the purpose of clustering. Five beverage clusters were identified from standardized age 13–17 mean daily beverage intakes and named by the authors for the dominant beverage: juice, milk, water/SFB, neutral and SSB. Outcome Age 17 weight, height and BMI. Statistical analyses Ward’s method for clustering of beverage variables. One-way ANOVA and chi-square tests for bivariable associations. Gamma regression for associations of weight or BMI (outcomes) with beverage clusters and demographic variables. Linear regression for associations of height (outcome) with beverage clusters and demographic variables. Results Participants with family incomes < $60,000 trended shorter (1.5±0.8 cm; P=0.070) and were heavier (2.0±0.7 BMI units; P=0.002) than participants with family incomes ≥ 60,000/year. Adjusted mean weight, height and BMI estimates differed by beverage cluster membership. For example, on average, male and female members of the neutral cluster were 4.5 cm (P=0.010) and 4.2 (P=0.034) cm shorter, respectively, than members of the milk cluster. For members of the juice cluster, the mean BMI was lower than for members of the

Reproductive Tract Infections and Treatment Seeking Behavior among Married Adolescent Women 15-19 Years in India

PubMed Central

Prusty, Ranjan Kumar; Unisa, Sayeed

2013-01-01

Background: India is home to the highest number of adolescents in the world. Adolescents in India suffer from lack of knowledge and empowerment to make informed sexual and reproductive health decisions. This paper analyses the prevalence of reproductive tract infections and sexually transmitted infections (RTI/STI) and treatment seeking behavior among married adolescent women in India aged 15-19 years. Methods: Data from the District Level Household Survey (DLHS, 2007-08) of India were used. The prevalence of RTIs symptoms and treatment seeking behavior among women by different socio-demographic characteristics was analyzed. Factor analysis was utilized to create an index using information about 11 symptoms of RTI/STI collected in the survey. Linear and binary logistic regressions were used to know the association between infections and treatment seeking behavior with socio-demographic factors. Results: About 15 percent of adolescent women reported having any symptoms of RTI/STI. The main symptoms reported were low backache, pain in the lower abdomen, pain during intercourse and itching or irritation around the vulvar region. Factor analysis showed the concentration of diseases in three clusters - infection in around the vulva, other reproductive infection and abnormal discharge; and intercourse related problems. Major predictors of both symptoms of reproductive infections and treatment seeking behavior from multivariate analysis are age, education, wealth, region and awareness about RTI/STI. Conclusions and Public Health Implications: Knowledge and treatment seeking behavior is poor among adolescent women in India. There is need for programmatic and policy emphasis on increasing knowledge and awareness through family life education including in educational curriculum at school level. PMID:27621963

Prevalence of self-reported musculoskeletal pain symptoms among school-age adolescents: age and sex differences.

2018-04-25

Non-specific musculoskeletal pain symptoms are common in adolescents and may differ between the sexes, and be related to age and daily activities. It is critical to examine the prevalence and frequency of symptoms in adolescent students who tend to have pain which interferes with their routine activities. This study aimed to explore the prevalence and frequency of self-reported musculoskeletal pain symptoms by age and sex, and we also examined the association of symptoms with routine activities of school-age adolescents by area of pain. A cross-sectional survey was conducted among Thai students aged 10-19 years. All 2,750 students were asked to report previous 7-day and/or 12-month pain using the Standardized Nordic Questionnaire (Thai version) in 10 body areas. Multivariable logistic regression adjusted for age and sex was used to analyze the association between daily activity and musculoskeletal pain symptoms. A total of 76.1% (n=2,093) of students reported experiencing pain in the previous 7 days, 73.0% (n=2,007) reported in the previous 12-month period and 83.8% (n=2,304) reported pain in both 7-day and 12-month periods. The most common pain area was from a headache, with other areas being neck and shoulders, in that order, for both periods of time. The prevalence of musculoskeletal pain was especially higher in older groups and females. Participants reported frequency of pain as "sometimes in different areas" ranging from 78.4% to 88% and severity of pain at 3.82±2.06 out of 10 (95% CI 3.74-3.91). Routine daily activities associated with symptoms of headache, neck, shoulders, and ankles or feet pain were computer use (head, OR=2.22), school bag carrying (neck, OR=2.05), school bag carrying (shoulder, OR=3.09), and playing sports (ankle or foot, OR=2.68). The prevalence of musculoskeletal pain symptoms was high in both the previous 7-day and 12-month periods, especially in females and older adolescents, although most of them sometimes experienced pain

Aim and objectives To investigate differences in sexual-risk factors between adolescent girls reporting similar-aged or older sex partners. Background Adolescent girls are at significant risk for heterosexual-acquired HIV infection and other long term reproductive health issues. Sexual partner age-discordance in teen girls has been correlated with STIs, lack of protection, multiple partners, and earlier age of sexual transition. Design A descriptive study comparing girls currently involved with age-discordant partners to those with similar-aged partners. Two-sample t-test for continuous variables and for categorical variables, Chi-square or Fisher exact test were used to compare groups. Methods Baseline data from 738 sexually-active, urban, adolescent girls ages 15 to 19, were analyzed to determine which behaviors were more likely to occur in girls with older partners. Data were collected as part of a gender specific HIV-prevention intervention in a randomized controlled trial tailored to adolescent girls. Results Multiple reported sexual risk behaviors were found to significantly differ between the two groups at baseline. Overall, girls with older partners had more episodes of sexual instances (vaginal, anal, and oral). Specific sexual risk behaviors were found to be statistically significant between the two groups. Girls with older partners started having sex at earlier ages, had more lifetime sexual partners, higher incidents of STIs and were reluctant to discuss using condoms with their partners. Girls with similar-aged partners were less willing to engage in risky sexual behaviors. Conclusions Findings from this investigation support data from other studies. Relationships with older male partners place adolescent girls at increased risk for HIV/STIs and unintended pregnancy. Relevance to clinical practice Adolescent girls in age-discordant relationships are at risk for immediate and long term sexual health morbidities. Identifying girls who are at increased

This study examined the psychometric properties of the Defense Style Questionnaire (DSQ-40) in adolescents. Internal consistency, factor structure, and discriminant and concurrent validity of the DSQ-40 were studied in 211 adolescent psychiatric outpatients aged 13 to 19 years and 199 age-matched and sex-matched controls. Principal components analysis yielded four internally consistent components: mature, neurotic, image-distorting, and immature defense styles. The outpatients reported more immature, image-distorting, and neurotic styles and less mature style than did the controls, suggesting adequate discriminant validity. As a demonstration of convergent and concurrent validity, the severity of psychiatric symptoms assessed by the General Health Questionnaire and psychosocial adjustment assessed by the Global Assessment of Functioning Scale correlated theoretically meaningfully with the different defense styles. The DSQ-40 appears to be a reliable and valid instrument for adolescents.

Parental and peer disapproval of alcohol use and its relationship to adolescent drinking: age, gender, and racial differences.

PubMed

Mrug, Sylvie; McCay, Riley

2013-09-01

This study examined age, gender, and racial differences in parental and peer disapproval of alcohol use and in the relationship of these injunctive norms with drinking during adolescence. Participants included 20,239 students ages 11-19 years (average age 14.34; 47% boys; 46% White and 54% Black) from 2 large urban and suburban school districts. Youth responded to a cross-sectional, school-administered Pride Survey in the spring of 2004. Adolescents reported how often they used alcohol in the past year and their perceptions of peer and parental disapproval of alcohol use. The results revealed that youth perceived higher disapproval from parents than peers throughout adolescence, but this parent-peer disparity in norms increased with age as a result of steeper decline in peer than parental disapproval. Black youth perceived lower disapproval from both peers and parents than Whites in earlier but not later adolescence. Girls reported higher perceptions of both parental and peer disapproval than boys throughout adolescence. Alcohol use was more strongly related to peer than parental norms, and the effect of parental and peer disapproval on abstinence was larger among older youth. Peer norms were more closely associated with alcohol use in girls than boys. Both parent and peer injunctive norms were also more strongly related to alcohol use in White than Black adolescents. Parental disapproval of drinking amplified the link between peer disapproval and lower alcohol use. These findings suggest that interventions should target both parental and peer disapproval throughout adolescence, particularly among White youth.

The present study aimed to identify dietary patterns and determine the relationship between dietary patterns and cognitive ability among 12- to 13 year-old Malay adolescents in the urban areas of Gombak district in Selangor, Malaysia. Data on sociodemographic background were obtained from parents. Height and weight were measured and BMI-for-age was determined. Adolescents were interviewed on their habitual dietary intakes using a semi-quantitative FFQ. Cognitive ability was assessed using the Wechsler Nonverbal Scale of Ability in a one-to-one manner. Dietary patterns were constructed using principal component analysis based on thirty-eight food groups of the semi-quantitative FFQ. Urban secondary public schools in the district of Gombak in Selangor, Malaysia. Malay adolescents aged 12 to 13 years (n 416). The mean general cognitive ability score was 101·8 (sd 12·4). Four major dietary patterns were identified and labelled as 'refined-grain pattern', 'snack-food pattern', 'plant-based food pattern' and 'high-energy food pattern'. These dietary patterns explained 39·1 % of the variance in the habitual dietary intakes of the adolescents. The refined-grain pattern was negatively associated with processing speed, which is a construct of general cognitive ability. The high-energy food pattern was negatively associated with general cognitive ability, perceptual reasoning and processing speed. Monthly household income and parents' educational attainment were positively associated with all of the cognitive measures. In multivariate analysis, only the high-energy food pattern was found to contribute significantly towards general cognitive ability after controlling for socio-economic status. Consumption of foods in the high-energy food pattern contributed towards general cognitive ability after controlling for socio-economic status. However, the contribution was small.

Recent studies demonstrate that infection with the Human Immunodeficiency Virus-1 (HIV) is associated with accelerated aging effects in adults according to a highly accurate epigenetic biomarker of aging known as epigenetic clock. However, it not yet known whether epigenetic age acceleration occurs as early as adolescence in perinatally HIV-infected (PHIV+) youth. Observational study of PHIV and HIV-uninfected adolescents enrolled in the Cape Town Adolescent Antiretroviral Cohort (CTAAC) Study. The Illumina EPIC array was used to generate blood DNA methylation data from 204 PHIV and 44 age-matched, uninfected (HIV-) adolescents aged 9 to 12 years old. The epigenetic clock software and method was used to estimate two measures of epigenetic age acceleration. Each participant completed a comprehensive neuropsychological test battery upon enrolment to CTAAC. HIV is associated with biologically older blood in PHIV+ adolescents according to both measures of epigenetic age acceleration. One of the measures, extrinsic epigenetic age acceleration, is negatively correlated with measures of cognitive functioning (executive functioning, working memory, processing speed). Overall, our results indicate that epigenetic age acceleration in blood can be observed in PHIV+ adolescents and that these epigenetic changes accompany poorer cognitive functioning.

Identifying Health Promotion Needs Among Dominican-American Adolescents.

PubMed

Champion, Jane Dimmitt; Roye, Carol F

Immigration from the Dominican Republic to the United States has grown rapidly. Yet, although adolescent pregnancy and obesity are common concerns among Hispanics, little is known specifically about Dominican adolescent health. This study was undertaken to assess Dominican-American adolescents' health concerns and their perceptions about their health promotion needs. Dominican-American adolescents (N=25) were recruited in a pediatric clinic in New York City which primarily serves a Dominican population. Eligibility criteria included age 13-21years, self-identifying as Dominican ethnicity, and able to speak and read English. They completed a questionnaire, with demographic questions and questions about their risk behaviors including sexual and substance use. After completing the questionnaire, they participated in a semi-structured interview addressing their health education experiences and suggestions for such programs. Quantitative data were analyzed using frequencies to provide a demographic and behavioral profile. Qualitative data were analyzed using thematic analysis. Twenty-five adolescents, ages 13-21years, (female N=19, male N=6) participated in the study. Most were in school (92%) and were sexually experienced (68%). Programmatic preferences included in-person programs rather than online. They spontaneously addressed the importance of cultural issues, and the need to address several issues in addition to sexuality, including obesity and substance use. Programming for this population should address a broad conceptualization of health, and incorporate Dominican cultural issues. Nurses working with adolescents of Dominican origin, should provide health education that incorporates the specific needs of this population, including culturally congruent face-to-face interventions.

Several studies have reported an increase in risk behaviors among adolescents after experience of parental divorce. The aim of the study was to investigate whether parental divorce is associated with risk behavior among adolescents independent of mental health problems, first when early divorce was experienced, and second after experience of late parental divorce. One prospective (n=1861) and one cross-sectional study (n=2422) were conducted using data from two Young-HUBRO surveys in Oslo, Norway. All 15/16 year-old 10(th) grade students who participated in the first survey in the school year 2000/01 were followed-up in 2004 when they were 18/19 year-olds. The follow-up rate was 68%. The prospective study investigated the influence of late parental divorce that occurred between the age of 15/16 and 18/19. In the cross-sectional study we focused on early parental divorce that occurred before the participants were 15/16 year-old. In the prospective study we could not discern a significant association between experiencing late parental divorce and an increase in risk behaviors among 18/19 year-old adolescents. In the cross-sectional study parental divorce was significantly associated with cigarette smoking and using doping agents. Parental divorce that occurs when the children of divorced parents are 15/16 year-old or younger is associated with an increase in cigarette smoking and use of doping agents. However, no evidence of significant association is found between experience of late parental divorce and risk behaviors in late adolescence.

2015-12-01

First- and second-born adolescents' and their parents' perceptions of adolescents' decision-making autonomy were compared from ages 12 to 19 in a longitudinal sample of 145 predominantly White, middle class families. Utilizing a multivariate, multilevel modeling approach, differences in perceptions of adolescents' autonomy between parents and each adolescent, as well as by social-cognitive domain were examined. The present study found that when comparing parents' perceptions of their children at the same age, second-borns were granted more autonomy regarding conventional issues than first-borns during early adolescence, but by later adolescence first-borns were granted more autonomy regarding prudential issues than second-borns. However, comparisons between adolescents' and siblings' perceptions showed no differences. Potential reasons for, and implications of, differences in perceptions of adolescent autonomy are discussed.

1985-01-01

A specialized obstetrical section for single adolescent mothers was created at a University of Chile hospital to test the hypothesis that adequate and appropriate medical care could improve the outcome for adolescent mothers and their infants. The team consisted of an obstetrician-gynecologist, a pediatrician, a psychologist, a midwife, a nurse, a social worker, and a nurse's aide. A nutritionist and a psychiatrist were later added. Between November 1981-March 1985, 610 pregnancies were followed and 490 deliveries were attended. The psychosocial characteristics of the 1st 300 adolescents were studied, the obstetrical and preinatal outcomes of the 1st 200 deliveries were compared with those of 200 deliveries of adolescents not participating in the prenatal program but delivering at the same hospital, and a 2nd control group of 100 single primaparas was used to compare maternal morbidity and mortality and neonatal pathology. 11.6% were aged 11-14, 32.7% were 15-16, 30.3% were 17, and the remainder were 18 or 19. 5% of the fathers were under 15, 33.3% were 15-19, and the rest were 20 or above. The father's age and other characteristics were unknown in 6 pregnancies resulting from rape. 1.3% of the mothers had no education, 67% had some basic education, and 31.7% had a middle level or higher. Of the adolescent mothers and the fathers respectively, 50.3% and 23.0% were students, 17.0% and 26.3% had stable employment, 32.7% and 12.0% had no economic activity, and 32.0% of fathers were subemployed. Only 35.7% of the adolescents mothers lived in stable family environments. 94.7% of the adolescents had negative attitudes on learning of their pregnancies, but 79.7% had positive attitudes when they began receiving prenatal care. 89.7% of the 213 legitimate adolescent mothers but only 64.4% of the 87 illegitimate mothers had positive attitudes toward their pregnancies at the end of the prenatal period. Cases were younger than either group of controls, with 27.0% of cases and

Coactivation of lower leg muscles during body weight-supported treadmill walking decreases with age in adolescents.

The kinematics of children's walking are nearly adult-like by about age 3-4 years, but metabolic efficiency of walking does not reach adult values until late in adolescence or early adulthood, perhaps due to higher coactivation of agonist/antagonist muscle pairs in adolescents. Additionally, it is unknown how use of a body weight-supported treadmill device affects coactivation, but because unloading will alter the activity of anti-gravity muscles, it was hypothesized that muscle coactivation will be altered as well. Muscle coactivation during treadmill walking was evaluated for adolescents (ages 10 to 17 years, M = 13.2, SD = 2.2) and adults (ages 22 to 35 years, M = 25.2, SD = 4.3), for thigh muscles (vastus lateralis/biceps femoris) and lower leg muscles (tibialis anterior/gastrocnemius). Conditions included body weight unloadings from nearly 0% to 80% of body weight, while walking at a preferred speed (self-selected, overground speed) or a reduced speed. Unloading was accomplished using a lower body positive pressure support system. Coactivation was found to be higher in adolescents than in adults, but only for the lower leg muscles.

Adult and adolescent social reciprocity: experimental data from the Trust Game.

Twenty-four adults (aged 19-35) and 27 adolescents (aged 13-14) played as 'Trustee' in an iterated Trust Game against a pre-programmed set of 'Investor' moves, said to belong to an unknown co-player. Trustee behaviour was examined first in response to normative Investor cooperation, and then in response to a period of social rupture caused by reduced investments. Adolescents were motivated by inequity aversion during normative Investor cooperation, whereas adults over-compensated the Investor. Participants were also identified as coaxers or non-coaxers based on how they responded to social rupture: 'coaxers' were individuals who made at least one relatively generous return to the Investor during this phase. A single coaxing move predicted consistently higher returns to Investors across both normative and reduced investments. Adults showed greater polarisation between coaxing and non-coaxing strategies than did adolescents. These data suggest that adults and adolescents may respond differently to periods of possible social rupture. Copyright © 2012 The Foundation for Professionals in Services for Adolescents.

This study presents data on the prevalence of different grades of nutritional status (thinness, normal weight, overweight and obesity) among Tuscan school-aged children from primary to high school (9-11-13-15-y-old), assessed by means of Body Mass Index, according to international definitions. From 2002 to 2006 the prevalence of thinness among children aged 9 years decreased from 4.6% to 4.2%, and the prevalence of normal weight from 63.7% to 62.4%; the prevalence of overweight (including obesity) rose from 31.7% to 33.4%. From 2004 to 2006, among pre-adolescents aged 11 years, the prevalence of thinness declined from 11.0% to 10.1%; the prevalence of normal weight rose from 68.4% to 70.2%, and the prevalence of overweight declined from 20.7% to 19.6%. Among adolescents aged 13 years, the prevalence of thinness declined from 9.8% to 8.0%; the prevalence of normal weight rose from 73.5% to 74.0%, and the prevalence of overweight from 16.8% to 17.9%. Among adolescents aged 15 years, the prevalence of thinness declined from 9.8% to 8.7%, and the prevalence of normal weight from 77.0% to 71.6%, while the prevalence of overweight rose from 13.3% to 19.7%. The 2006 data showed that the trend in the prevalence of overweight (including obesity) tended to decrease with age for both sexes, though more markedly in girls (from 34.0% at 9-y of age to 12.2% at 15-y of age) than in boys (from 32.8% at 9-y of age to 22.8% at 13-y of age to 27.5% at 15-y of age). By contrast, the prevalence of thinness increased with age in girls (from 4.9% at 9-y of age to 14,1% at 15-y of age), while boys presented a similar low prevalence at 9 and 15-y of age (3.3% and 3.1%), doubling the values at 11 and 13-y of age (7.5% and 6.5%). The trend in the prevalence of normal weight increased with age from 62.4% at 9-y of age to 74.0% at 13-y of age and to 71.6% at 15-y of age. Boys displayed a higher prevalence than girls only at 9-y of age (63.9% vs. 61.0%). The results of this study allow us to

Objective Research on the manifestations and health correlates of eating disorder symptoms among males is lacking. This study identified patterns of appearance concerns and eating disorder behaviors from adolescence through young adulthood and their health correlates. Method Participants were 7,067 males from the prospective Growing Up Today Study. Surveys from 1999–2007 (spanning ages 13–26 years) provided repeated measures data on: muscularity and leanness concerns; eating disorder behaviors (purging, overeating, binge eating, use of muscle-building products); and health correlates (obesity, non-marijuana drug use, binge drinking, and depressive symptoms). Results Latent class analyses of observations at ages 13–15, 16–18, 19–22, and 23–26 identified one large Asymptomatic class and four symptomatic patterns: Body Image Disturbance (high appearance concerns, low eating disorder behaviors; 1.0%–6.0% per age period); Binge Eating/Purging (binge eating and purging, use of muscle-building products, low appearance concerns; 0.1%–2.5%); Mostly Asymptomatic (low levels of muscularity concern, product use, and overeating; 3.5%–5.0%); and Muscularity Concerns (high muscularity concerns and use of products; 0.6%–1.0%). The Body Image Disturbance class was associated with high estimated prevalence of depressive symptoms. Males in the Binge Eating/Purging and Muscularity Concerns classes had high prevalence of binge drinking and drug use. Despite exhibiting modestly greater appearance concerns and eating disorder behaviors than the Asymptomatic class, being in the Mostly Asymptomatic class was prospectively associated with adverse health outcomes. Conclusion Results underscore the importance of measuring concerns about leanness, muscularity, and use of muscle-building products when assessing eating disorder presentations among males in research and clinical settings.

Feedback processing in adolescence: an event-related potential study of age and gender differences.

2014-01-01

Adolescence has frequently been characterized as a period of increased risk taking, which may be largely driven by maturational changes in neural areas that process incentives. To investigate age- and gender-related differences in reward processing, we recorded event-related potentials (ERPs) from 80 participants in a gambling game, in which monetary wins and losses were either large or small. We measured two ERP components: the feedback-related negativity (FRN) and the feedback P3 (fP3). The FRN was sensitive to the size of a win in both adult (aged 23-35 years) and adolescent (aged 13-17 years) males, but not in females. Small wins appeared to be less rewarding for males than for females, which may in part explain more approach-driven behavior in males in general. Furthermore, adolescent boys showed both delayed FRNs to high losses and less differentiation in FRN amplitude between wins and losses in comparison to girls. The fP3, which is thought to index the salience of the feedback at a more conscious level than the FRN, was also larger in boys than in girls. Taken together, these results imply that higher levels of risk taking that are commonly reported in adolescent males may be driven both by hypersensitivity to high rewards and insensitivity to punishment or losses. © 2014 S.

In 1996, India included Adolescent Health in Reproductive and Child Heatlh Programme. This Task-Force Study was planned to test the awareness level of adolescents regarding various reproductive health issues and to identify lacunae in knowledge, particularly in legal minimum age of marriage, number of children, male preference, contraceptive practices, about STIs /AIDS etc. It was a multicentre study, done in rural co-education/higher secondary schools of 22 districts located in 14 states through Human Reproductive Research Centre (HRRC's) of the Indian Council of Medical Research (ICMR). A sample of 8453 school going adolescents (aged 10-19 years) was surveyed by means of open ended, self-administered questionnaires maintaining confidentiality. Mean age of adolescents was 14.3 +/- 3.4 years. Awareness of legal minimum age of marriage was present in more than half of adolescents. Attitude towards marriage beyond 21 years in boys and 18 years in girls was favorable. Mean number of children desired was 2.2 +/- 1.4. However, number of children desired by boys (2.2+/-1.6) was significantly more (p< 0.000) than those desired by girls (2.0+/-1.1). More boys (23.7%) than girls (9.4%) wanted three or more children with male preference. Only 19.8% of adolescents were aware of at least one method of contraception. Only two-fifth (39.5%) were aware of AIDS and less than one-fifth (18%) were aware of STDs and most of them thought it is same as AIDS. Awareness of at least one method of immunization was present in three-fifth (60.1%) of students. It was least for DPT (13.5%) and most (55%) were aware of polio only. Awareness of all Reproductive Health matters was more in boys than girls and more in late teens (15-19) than earlier teens (10-14). The study showed tremendous lacunae in awareness of all Reproductive Health (RH) matters. There is a need for evolving information, education, and communication strategies to focus on raising awareness on RH and gender related issues. A

The literature on relative age position effects is rather inconsistent. In this study we examined intra-classroom age position (or relative age) effects on Dutch adolescents’ school progress and performance (as rated by teachers), physical development, temperamental development (fear and frustration), and depressive symptoms, all adjusted for age at the time of measurement. Data were derived from three waves of Tracking Adolescents' Individuals Lives Survey (TRAILS) of 2230 Dutch adolescents (baseline mean age 11.1, SD = 0.6, 51% girls). Albeit relative age predicted school progress (grade retention ORs = 0.83 for each month, skipped grade OR = 1.47, both p<.001), our key observation is the absence of substantial developmental differences as a result of relative age position in Dutch adolescents with a normative school trajectory, in contrast to most literature. For adolescents who had repeated a grade inverse relative age effects were observed, in terms of physical development and school performance, as well as on depressive symptoms, favoring the relatively young. Cross-cultural differences in relative age effect may be partly explained by the decision threshold for grade retention. PMID:26076384

Many adolescents are exposed to violence in their schools, communities and homes. Exposure to violence at high levels or across multiple contexts has been linked with emotional desensitization, indicated by low levels of internalizing symptoms. However, the long-term consequences of such desensitization are unknown. This study examined emotional desensitization to violence, together with externalizing problems, as mediators of the relationship between exposure to violence in pre-adolescence and violent behavior in late adolescence. A community sample of youth (N = 704; 48% female; 76% African American, 22% Caucasian) reported on their exposure to violence in multiple settings at ages 11, 13 and 18. Internalizing and externalizing problems were assessed at ages 11 and 13; violent behavior was measured at age 18. Structural Equation Modeling showed that exposure to high levels of violence at age 11 was associated with lower levels of internalizing problems (quadratic effect) at age 13, as was exposure to violence across multiple contexts (linear effect). In turn, fewer internalizing problems and more externalizing problems at age 13 predicted more violent behavior at age 18. The results suggest that emotional desensitization to violence in early adolescence contributes to serious violence in late adolescence.

We examined developmental trajectories of creative cognition across adolescence. Participants (N = 98), divided into four age groups (12/13 yrs, 15/16 yrs, 18/19 yrs, and 25-30 yrs), were subjected to a battery of tasks gauging creative insight (visual; verbal) and divergent thinking (verbal; visuo-spatial). The two older age groups outperformed the two younger age groups on insight tasks. The 25-30-year-olds outperformed the two youngest age groups on the originality measure of verbal divergent thinking. No age-group differences were observed for verbal divergent thinking fluency and flexibility. On divergent thinking in the visuo-spatial domain, however, only 15/16-year-olds outperformed 12/13-year-olds; a model with peak performance for 15/16-years-old showed the best fit. The results for the different creativity processes are discussed in relation to cognitive and related neurobiological models. We conclude that mid-adolescence is a period of not only immaturities but also of creative potentials in the visuo-spatial domain, possibly related to developing control functions and explorative behavior. © 2012 Blackwell Publishing Ltd.

Evidence suggests an inverse relationship between excess weight and health-related quality of life (HRQoL) in children and adolescents, however little is known about whether this association is moderated by variables such as gender and age. This study aimed to investigate these relationships. Participants were secondary school students (818 females, 52% and 765 males, 48%) from 23 secondary schools in Victoria, Australia. Age ranged from 11.0 to 19.6 years (mean age 14.5 years). The adolescent version of the Assessment of Quality of Life (AQoL) Instrument (AQoL-6D) which is a self-reported measure of adolescent quality of life was administered and anthropometric measures (height and weight) were taken. Assessment of weight status was categorized using the Body Mass Index (BMI). HRQoL was associated with gender and age, but not weight status or socio-economic status; with males and younger adolescents having higher HRQoL scores than their female and older adolescent counterparts (both p < 0.05). There was also a significant interaction of weight status by gender whereby overweight females had poorer HRQoL (-.06 units) relative to healthy weight females (p < 0.05). This study contributes to the evidence base around factors associated with adolescent HRQoL and reveals that gender and age are important correlates of HRQoL in an Australian adolescent population. This knowledge is critical to inform the design of health promotion initiatives so they can be tailored to be gender- and age-specific. Australian Clinical Trials Registration Number 12609000892213.

Developmentally sensitive markers of personality functioning in adolescents: Age-specific and age-neutral expressions.

Criterion D of the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5 ; American Psychiatric Association [APA], 2013) refers to a possible onset of personality disorders (PDs) in adolescence and in Section II the development/course in adolescence is described by some typical characteristics for several PDs. Yet, age-specific expressions of PDs are lacking in Section III. We urgently need a developmentally sensitive assessment instrument that differentiates developmental and contextual changes on the one hand from expressions of personality pathology on the other hand. Therefore we investigated which items of the Severity Indices for Personality Problems-118 (SIPP-118) were developmentally sensitive throughout adolescence and adulthood and which could be considered more age-specific markers requiring other content or thresholds over age groups. Applying item response theory (IRT) we detected differential item functioning (DIF) in 36% of the items in matched samples of 639 adolescents versus 639 adults. The DIF across age groups mainly reflected a different degree of symptom expressions for the same underlying level of functioning. The threshold for exhibiting symptoms given a certain degree of personality dysfunction was lower in adolescence for areas of personality functioning related to the Self and Interpersonal domains. Some items also measured a latent construct of personality functioning differently across adolescents and adults. This suggests that several facets of the SIPP-118 do not solely measure aspects of personality pathology in adolescents, but likely include more developmental issues.

Non-specific low back pain is a prevalent symptom in adolescents and is recurrent in some instances. Recent studies have highlighted the marked impact the condition has on daily life of adolescents. However, it is unclear if parents of adolescents reporting recurrent non-specific low back pain know about their child's status. The purpose of the study was to determine the level of agreement between adolescents and their parents in reporting recurrent non-specific low back pain in Harare, Zimbabwe. This cross-sectional study formed part of a large study carried out to ascertain the prevalence of non-specific low back pain in Zimbabwean adolescents. Six hundred and twenty (n = 620) Medical Health Questionnaires were sent to parents. School-children with returned questionnaires and informed consents signed were subsequently eligible to participate. A reliable and validated low back pain study questionnaire was administered to 544 adolescents between the ages of 13 and 19 years randomly selected from government-administered schools. The questionnaire sought to determine adolescents with recurrent NSLBP. The Kappa statistic (k) was used to analyse agreement between adolescents and parental reports on recurrent NSLBP status. Parental and school-children response rates were acceptable (90.3 and 97.8 %, respectively). The prevalence of recurrent NSLBP was 28.8 % [95 % Confidence Interval, CI = 26.0-31.6]. Both sexes were equally affected [χ (2) (1) =0.19, p = 0.67]. The prevalence increased with age in both sexes [χ (2) trend =90.9, p < 0.001]. Parental reports agreed in 16.3 and 98.7 % for the adolescents with and without recurrent NSLBP respectively. The value of kappa (k) was 0.20 [SE = 0.04; 95 % CI, 0.13-0.27] with a prevalence index and bias index of -0.65 and 0.23, respectively. These results suggest poor strength of the agreement. Recurrent non-specific low back pain is relatively common among Zimbabwean adolescents. Most of the parents of

This cross-sectional study of children aged 6-7 years and adolescents aged 13-14 years in Bogotá, Colombia, assessed the prevalence of asthma symptoms and their associations with dietary, health, and behavioral habits. This study is part of the International Study of Asthma and Allergies in Childhood (ISAAC)-phase III. Asthma prevalence among the children was assessed using a parental self-administered written questionnaire (WQ), and among adolescents using a WQ together with a video questionnaire (VQ). Associations were estimated with bivariate and multivariate analysis. The study found that the 6-7 year age-group were more likely to report current asthma symptoms than the 13-14 year age-group (10.4% [WQ] vs. 8.6% [WQ] and 8.0% [VQ], respectively). Factors associated with current asthma symptoms among the 6-7 year age-group included higher maternal education (OR = 1.7, [95% CI 1.2-2.6], p = 0.007), a cat in the home during the last year (OR = 1.5, [95% CI 1.0-2.3], p = 0.036), watching TV 1-2 hours/day (OR = 2.1, [95% CI 1.2-3.9], p = 0.013), and medication with acetaminophen in the first and most recent year of life (OR = 1.8, [95% CI 1.3-2.4], p < 0.001; OR = 2.2, [95% CI 1.7-2.8], p < 0.001, respectively) or antibiotics in the first year of life (OR = 1.9, [95% CI 1.4-2.5], p < 0.001). Among the 13-14 year age-group, factors associated with current asthma symptoms included medication with acetaminophen during the last year (OR = 1.8, [95% CI 1.4-2.3], p < 0.001); cereal, milk, and fruit consumption 3 or more times weekly (OR = 1.5, [95% CI 1.1-1.9], p = 0.010; OR = 0.8, [95% CI 0.6-1.0], p = 0.046; OR = 0.6, [95% CI 0.4-1.0], p = 0.031, respectively). Overall, compared with that in other Latin American centers, asthma prevalence in Bogotá is close the lower estimates. However, associations with dietary, health, and behavioral habits need further study to assess their complex relationship with asthma.

The aim of this retrospective cohort study was to examine whether exposure to early childhood protein-energy malnutrition (ECPEM) is related to worsened periodontal status in the permanent dentition during adolescence. A trained clinician/researcher examined the periodontal status of 96 persons aged 12-19 living in rural Haiti using WHO diagnostic criteria (Community Periodontal Index, WHO 1997). Malnutrition data of the study participants had been collected during the years 1988-1993 by a nongovernmental organization. We compared those who had been malnourished in early childhood, based on z-scores for anthropomorphic data collected during the first 5 years of life, with those who had not been malnourished, regarding mean Community Periodontal Index (CPI) score, controlling for age, sex, socioeconomic status, and smoking. Overall, 57.3% of the participants demonstrated a CPI score of 3 or greater in at least one sextant. ECPEM was independently and positively related to mean CPI score, when controlling for sex and smoking. More than half of these young Haitians demonstrated CPI scores of 3 or greater, and ECPEM was related to poorer periodontal status, as measured by CPI, in the permanent dentition.

Objectives The objective of this study was to characterize symptom prevalence, awareness of pelvic floor disorders in family/friends, and understanding of factors contributing to the development of pelvic floor disorders (PFDs) in women ages 19–30. Methods A cross-sectional study via online questionnaire survey of female students ages 19–30 enrolled at the University of Alabama at Birmingham. Results of “adolescent women” ages 19–24 were compared to “young women” age 25–30. Results 1092 questionnaires were completed with the mean age being 23.5 ± 3.1 years old. The overall rate of urinary incontinence (UI) was 10.3% without a difference between adolescent and young women (p=0.61). There were no differences in rates of urgency urinary incontinence (UUI) (p=0.061), stress urinary incontinence (SUI) (p=0.29), or pelvic organ prolapse (POP) symptoms (p=0.56) between groups. There was no difference between groups in awareness of family members with UI, fecal incontinence (FI) or POP symptoms (p≥0.24). However, logistic regression showed that the young women were more likely to have received education regarding UI (aOR 2.6, 95% CI 1.8–3.6), FI (aOR 3.3, 95% CI 2.2–4.8), POP (aOR 2.9, 95% CI 2.1–4.2) and have greater understanding regarding causes of UI (aOR 2.9, 95% CI 1.7–4.8), FI (aOR 1.6, 95% CI 1.1–2.3 and POP (aOR 1.9, 95% CI 1.3–2.9). Conclusions Women ages 25–30 had more awareness and understanding of pelvic floor disorders compared to adolescent females. These data may have implications for primary prevention strategies of pelvic floor disorders. PMID:27171318

The current literature on determinants of behavior change in weight management lacks sufficient studies on type of motivation among children/adolescents, on perceived competence, and in relation to healthy eating. This study aimed to investigate type of motivation and levels of perceived competence for healthy diet and exercise, as well as general self efficacy among adolescents. We hypothesized that overweight/obese adolescents would demonstrate lower autonomous motivation and perceived competence regarding diet and exercise, and lower self-efficacy in general, and that the scores would be influenced by socioeconomic factors. Normal weight ( n  = 40, body mass index < 85% for age and gender) and overweight or obese adolescents ( n  = 60, body mass index ≥ 85% for age and gender) aged 13-18 years were recruited from pediatric ambulatory clinics. Information was collected about demographics, socioeconomic factors, and lifestyle behaviors. The study subjects completed a survey including the Treatment Self-Regulation Questionnaire (TSRQ) and the Perceived Competence Scale (PCS) for healthy eating and exercise, and the General Self-Efficacy Scale (GSES). Composite scores for the three scales were compared between the two groups using the using the two-sample t-test (for normal data) or the Mann-Whitney U test (for non-parametric data). Relationships between the composite scores and patient characteristics were determined using Pearson or Spearman's correlations. The average age of the total cohort was 15.9 ± 1.9 years. 54% were female, and 82% identified as Latino/Hispanic. In comparison to normal weight subjects, overweight/obese adolescents exhibited higher scores for controlled motivation (mean ± standard deviation 28.3 ± 9.3 vs 18.1 ± 8.1) and higher perceived competence [median and 25-75% interquartile range 22.5 (19.0-26.0) vs 20.0 (15.5-25.0)] in relation to eating a healthy diet.

Controversy continues with regard to decision making for operative treatment of adolescent clavicle fractures, while the literature continues to support operative treatment for select middle third fractures in adults. The purpose of our study was to evaluate the recent trends in nonoperative and operative management of adolescent clavicle fractures in the United States. Data were derived from a publicly available database of patients, PearlDiver Patient Records Database. The database was queried for ICD-9 810.02 (closed fracture of shaft of clavicle), with the age restriction of either 10 to 14 or 15 to 19 years old, along with CPT-23500 (closed treatment of clavicular fracture) and CPT-23515 (open treatment of clavicular fracture) from 2007 to 2011. The χ analysis was used to determine statistical significance with regard to procedural volumes, sex, and region. The Student t test was used to compare average charges between groups. A significant increase in the number of adolescent clavicle fractures managed operatively (CPT-23510, ages 10 to 19 y) from 309 in 2007 to 530 in 2011 was observed (P<0.0001). There was a significantly greater increase in operative management of clavicle fractures in the age 15 to 19 subgroup compared with the age 10 to 14 subgroup (P<0.0001). In the operative group, there was a trend toward a higher number of males being managed with operative intervention. The overall average monetary charge for both nonoperatively and operatively managed adolescent clavicle fractures increased significantly in the study period. A statistically significant increase in normalized incidence of operatively managed adolescent clavicle fractures was noted in the midwest, south, and west regions with the greatest increase in west region where the incidence increased over 2-fold (P<0.0001). Adolescent clavicle fractures seem to be being treated increasingly with open reduction and internal fixation recently, especially in the 15 to 19 age group. Nevertheless

Observing Interactions between Children and Adolescents and their Parents: The Effects of Anxiety Disorder and Age.

PubMed

Waite, Polly; Creswell, Cathy

2015-08-01

Parental behaviors, most notably overcontrol, lack of warmth and expressed anxiety, have been implicated in models of the development and maintenance of anxiety disorders in children and young people. Theories of normative development have proposed that different parental responses are required to support emotional development in childhood and adolescence, yet age has not typically been taken into account in studies of parenting and anxiety disorders. In order to identify whether associations between anxiety disorder status and parenting differ in children and adolescents, we compared observed behaviors of parents of children (7-10 years) and adolescents (13-16 years) with and without anxiety disorders (n = 120), while they undertook a series of mildly anxiety-provoking tasks. Parents of adolescents showed significantly lower levels of expressed anxiety, intrusiveness and warm engagement than parents of children. Furthermore, offspring age moderated the association between anxiety disorder status and parenting behaviors. Specifically, parents of adolescents with anxiety disorders showed higher intrusiveness and lower warm engagement than parents of non-anxious adolescents. A similar relationship between these parenting behaviors and anxiety disorder status was not observed among parents of children. The findings suggest that theoretical accounts of the role of parental behaviors in anxiety disorders in children and adolescents should distinguish between these different developmental periods. Further experimental research to establish causality, however, would be required before committing additional resources to targeting parenting factors within treatment.

This study examined the location and time of adolescent use of cigarettes, alcohol, and marijuana. Age, gender, and racial differences in location and time of use were studied for each substance. Using cross-sectional data collected through the schoolwide Pride Survey, 20,055 students between the ages of 10 and 19 years (53.6% female, 55.1% Black, 44.9% White) in one metropolitan area reported on their frequency of cigarette, alcohol, and marijuana use, as well as the location and time of use of each substance. Chi-square tests compared the rates, locations, and times for each substance across boys and girls; Black and White students; and early, middle, and late adolescents. Older adolescents reported higher rates of substance use at friends' homes, at school, and in cars and lower rates of alcohol use at home compared with younger youth. Males were more likely to report alcohol and marijuana use at school and on weeknights and alcohol use in cars, whereas females were more likely to report alcohol and marijuana use on the weekends. No gender differences emerged for times and locations of cigarette use. Compared with Black youth, White adolescents were more likely to use all substances at friends' homes and on weekends; to smoke cigarettes at school, in the car, and on weeknights; and to use alcohol at home. Black adolescents were more likely to report using alcohol at home, at school, in cars, during and after school, and on weeknights and were more likely to report using marijuana at school. The location and time of adolescent substance use vary substantially by age, gender, and race. These differences may help tailor substance use prevention and intervention programs to specific subgroups of youth to improve program effectiveness.

Although within Latin America Chile has one of the lowest birth rates among adolescents, it has a high rate in comparison to other developed nations. To explore trends in birth rates among adolescents by selected demographics in Chile. The national trend in birth rates was examined for women aged 15-19 years between 1992 and 2012. The birth rates for regions and communes were calculated using birth and census data and were analysed to determine its relationship to the regional or communal poverty rate, which were obtained from the Casen Survey. Differences in educational attainment were explored among adolescents with first-order and second-order or higher births using the Chi-square test. The birth rate among adolescents has experienced a 25% decline in the past 20 years. Cross-regional variance in birth rates could not be explained by poverty rates. Within the Metropolitan Region, there is a positive correlation between poverty and adolescent birth rates. Among adolescents giving birth, 67% had completed 10-12 years of school at birth, but there is a significant difference in educational attainment between girls with a first-order and those with a higher-order birth. In Chile, the adolescent birth rate varies greatly among regions and communes. This study found that urban and wealthy areas had lower birth rates than poor and rural ones, and that girls with a first-order birth had completed more years of school than girls with higher-order births. © Faculty of Sexual and Reproductive Healthcare of the Royal College of Obstetricians and Gynaecologists (unless otherwise stated in the text of the article) 2017.

Globally, adolescent women are at risk for gender-based violence (GBV) including sexual violence and intimate partner violence (IPV). Those in economically distressed settings are considered uniquely vulnerable. Female adolescents aged 15-19 from Baltimore, Maryland, USA; New Delhi, India; Ibadan, Nigeria; Johannesburg, South Africa; and Shanghai, China (n = 1,112) were recruited via respondent-driven sampling to participate in a cross-sectional survey. We describe the prevalence of past-year physical and sexual IPV, and lifetime and past-year non-partner sexual violence. Logistic regression models evaluated associations of GBV with substance use, sexual and reproductive health, mental health, and self-rated health. Among ever-partnered women, past-year IPV prevalence ranged from 10.2% in Shanghai to 36.6% in Johannesburg. Lifetime non-partner sexual violence ranged from 1.2% in Shanghai to 12.6% in Johannesburg. Where sufficient cases allowed additional analyses (Baltimore and Johannesburg), both IPV and non-partner sexual violence were associated with poor health across domains of substance use, sexual and reproductive health, mental health, and self-rated health; associations varied across study sites. Significant heterogeneity was observed in the prevalence of IPV and non-partner sexual violence among adolescent women in economically distressed urban settings, with upwards of 25% of ever-partnered women experiencing past-year IPV in Baltimore, Ibadan, and Johannesburg, and more than 10% of adolescent women in Baltimore and Johannesburg reporting non-partner sexual violence. Findings affirm the negative health influence of GBV even in disadvantaged urban settings that present a range of competing health threats. A multisectoral response is needed to prevent GBV against young women, mitigate its health impact, and hold perpetrators accountable. Copyright © 2014 Society for Adolescent Health and Medicine.

Kunzmann, Ute; Wieck, Cornelia; Dietzel, Cathrin

2018-02-01

This study investigated age differences in empathic accuracy, the ability to correctly perceive others' emotions, in a sample of 151 boys and men from three age groups: adolescents (M age  = 16 years, SD = 1.04), young adults (M age  = 29 years, SD = 2.78), and middle-aged adults (M age  = 50 years, SD = 3.07). All participants viewed nine newly developed film clips, each depicting a boy or a man reliving one of three emotions (anger, sadness, or happiness), while talking about an autobiographical memory. Adolescents and middle-aged men were less accurate than young men, and these age differences were associated with parallel age differences in fluid-mechanical abilities. In addition, age differences in vocabulary, one indicator of crystallized-pragmatic intelligence, were associated with age differences in empathic accuracy in adolescent and young, but not middle-aged, men. Within the limitations of cross-sectional data, this study provides evidence for the idea that empathic accuracy is an effortful task that requires cognitive resources and, thus, may show a normative increase until young adulthood followed by periods of stability and decline in subsequent decades.

Sexual violence against children and adolescents is a serious threat to the rights and full health of this age group. This study aims to describe the characteristics of mothers aged up to 13, and analyze the profile of cases of notified rape in this age range and repercussions of this violence during pregnancy and childbirth. It is a comparative study of the characteristics of gestation and childbirth of girls aged up to 13 who have had children, without or with notification of rape, in the Violence & Accidents Vigilance (VIVA) System of the Brazilian Case Registry Database (Sistema de Informação de Agravos de Notificação - SINAN). A significant percentage (67.5%) of the girls aged up to 13 with children were of the black race/color category. There was repeated violence in 58.2% of cases. The notified rape victims have a higher percentage of birth by cesarean section, late onset and a lower number of prenatal consultations; and their babies had lower birthweight and lower 1-minute Apgar scores than mothers without rape notification. Rape of children and adolescents is an important risk factor that has repercussions during pregnancy, and complications in delivery and childbirth.

We assessed mobility in different life stages over a 29-year period from adolescence through adulthood and its correlation with psychosocial stress and vital exhaustion at ages 32 and 42 years. Data were derived from the Amsterdam Growth and Health Longitudinal Study, an observational longitudinal study of 420 boys and girls from age 13 to 42 years. Measurements included cumulative frequency of geographic relocation (CFGR), psychosocial stress (measured by a Dutch scale of experienced stress, VOEG-13), vital exhaustion (measured by the Maastricht Questionnaire, MQ), demographics, socioeconomic status, and other background characteristics. From 1976 to 2006, total CFGR was 3.56 ± 1.89 (range 0-13). Frequent geographic relocation during 2 life stages (age 22-32 years and 33-42 years) was significantly interrelated; however, this was not evident at age 13 to 21 years, which suggests a unique exposure to relocation during adolescence and youth. After adjusting for anticipated confounders, higher cumulative frequencies of residential changes during adolescence and youth were markedly associated with psychosocial stress and vital exhaustion at ages 32 and 42 years. Frequent geographic relocation during adolescence and youth was an indicator of psychosocial stress and vital exhaustion in the transition to middle adulthood. Further consideration of the pathways in this web of causation may aid in stress prevention and minimize negative consequences.

Purpose To verify the influence of overweight and alteration in the perception of the corporal image during the triage of eating disorders. Method A food disorder triage was performed in adolescents with 10 to 19 years of age using the Eating Attitudes Test (EAT-26), Children's Eating Attitudes Test (ChEAT), and Bulimic Investigatory Test Edinburgh (BITE), as well as a nutritional status evaluation. The perception of body image was evaluated in a subsample of adolescents with 10 to 14 years of age, using the Brazilian Silhouette Scale. The project was approved by the Human Research Ethics Committee of the Federal University of Viçosa, Minas Gerais, Brazil. Results The prevalence of eating disorder triage was 11.4% (n = 242) for the 2,123 adolescents evaluated. Overweight was present in 21.1% (n = 447) of the students, being more prevalent in the early adolescence phase, which presented levels of distortion of 56.9% (n = 740) and dissatisfaction of 79.3% (n = 1031). Body dissatisfaction was considered as a risk factor, increasing by more than 13 times the chance of TA screening. Conclusion Overweight was correlated with the ED triage and body dissatisfaction was considered as a risk factor, increasing the chances of these disorders by more than 13 times. PMID:28856236

Adolescent sexual behavior in the eighties.

PubMed

Bigler, M O

1989-10-01

This paper summarizes what is known about adolescent sexual behavior in the 1980s. One study found that 85% of American teens have had a boyfriend or girlfriend. Overall, 43% of teens have participated in vaginal play and 40% have experienced penile manipulation. A significant number of teenagers report having participated in oral sex. Many adolescents also report that they masturbate. Surveys of American adolescents have found that, on the whole, average age at 1st intercourse ranges from 16 to 16.9 years, but some teenagers begin to have intercourse shortly after puberty. The proportion of sexually-experienced teens increases with age. Many adolescents see their 1st experience sexual intercourse as a conscious, personal choice. At all ages, males are more likely to report having had intercourse than are females. Many adolescents who have had intercourse report regular contraceptive use. More than 1/3 (33%-39%) report contraceptive use every time they engage in intercourse. However, a large number of sexually experienced teenagers use contraception irregularly. Teenagers who have had intercourse express a preference for birth control pills over condoms as their primary means of contraception. Inconsistent contraceptive use among teens is reflected in the number of adolescent pregnancies in the US each year. In 1984, there were 233 adolescent pregnancies/1000 sexually active 15-19-year-old females. A large share of adolescent pregnancies end in abortion. 1 in 7 teens contracts a sexually transmitted disease each year. Many believe that teens are at high risk of infection with Human Immunodeficiency Virus (HIV) because of poorly protected sexual experimentation and intravenous drug use. Healthy adult sexuality may depend a great deal on the earlier years of sexual development.

Street hawking is the commonest form of child labor in Nigeria. Although street hawking is very pervasive, there is the increasing need to fully understand its pattern and effects on those involved in hawking particularly adolescents who combine schooling with hawking. In Nigeria, data on the effects of street hawking on in-school adolescents are generally scanty. Therefore, the present study was undertaken in Ife Central Local Government Area (LGA) of Osun State, Nigeria to assess the pattern, determinants of street hawking among in-school adolescents and its effect on school performance. A cross-sectional study of 435 adolescents (aged 10-19) attending public secondary schools was done. Data were collected using facilitated self-administered questionnaires alongside a review of class records. Appropriate statistical analysis including multiple regression was done. Results showed mean age of respondents to be 14.6±2.1 years with prevalence of street hawking at 37.2%. Early adolescents (10-13 years) were more likely to engage in street hawking compared to their counterparts in late adolescence (aged 17-19). Female adolescents and students of trading mothers were significantly more likely to engage in street hawking. Respondents engaged in street hawking were significantly more likely to have failed the last academic term examination. The findings from this study will be useful for stakeholders as they develop policies and programmes to address the challenge of street hawking among adolescent school goers.

Sexting (sexual messaging via mobile devices) among adolescents may result in increased risky sexual practices, psychological distress and in some cases, suicide. There is very little research on sexting in developing nations, such as Peru. In particular, little is known about gender differences in the correlates of sexting. The purpose of this study was to determine the sexting prevalence and correlates of sexting among adolescent boys and girls in Cusco, Peru. The study sample comprised 949 high school aged adolescents from Cusco, Peru. Adolescents responded to questions about demographics, sexting behavior, and risk/protective factors. Separate regression models were constructed to compare correlates of sexting for boys and sexting for girls. Twenty percent of the sample reported engaging in at least one instance of sexting. Boys reported higher rates of sexting than girls (35.17% vs. 13.19%, p = 0.000). Significant correlates for girls' sexting included having been cyberbullied and parental factors. For boys, hypertexting, fighting, parental factors, and parental rules about sexting were significant. Peruvian health officials with an interest in reducing the effects of sexting among adolescents may choose to target boys differently than girls. These efforts may include advising parents to set clear rules and expectations about sexting and the appropriate use of mobile devices.

To assess the impact of acanthosis nigricans (AN) on depression symptoms, related quality of life and self-esteem scores in obese adolescent girls. Fifty-nine obese adolescent girls (mean age: 13.19±1.3 years, age range: 12-17 years, mean body mass index: 29.89±3.30) were enrolled in this study. The obese adolescent girls were divided into two groups based on presence or absence of AN. Non-obese healthy adolescents constituted the control group (30 girls, mean age: 13.5±1.4 years). All subjects were evaluated using the Children's Depression Inventory (CDI), the State-Trait Anxiety Inventory for Children (STAI-C), and the modified Rosenberg Self-Esteem Scale (SES). Higher scores indicated more severe depression and anxiety, as well as low self-esteem status. The AN and non-AN obese groups showed significantly higher CDI, STAI-C and SES scores than the control group, and the two obese groups demonstrated no significant differences for these scores. The AN obese group with higher total testosterone levels (>50 ng/dL) had higher scores for SES (2.55±1.8 vs. 1.42±1.2; p=0.03) than the AN obese group with low total testosterone levels. SES scores significantly correlated with total testosterone levels (r=0.362; p=0.03) and fasting insulin (r=0.462; p=0.03) in the AN obese group. Higher SES scores (low self-esteem status) were determined in obese adolescents with acanthosis and were related to hyperandrogenism. This study also showed that a high testosterone level may be one of the important indicators of low self-esteem status in obese girls with AN.

Studies in India have reported a high prevalence of nutritional anemia among children and adolescent girls. Nutritional anemia is associated with impaired mental, physical, and cognitive performance in children and is a significant risk factor for maternal mortality. To evaluate the effect of a community-led initiative for control of nutritional anemia among children 6 to 35 months of age and unmarried rural adolescent girls 12 to 19 years of age. This Participatory Action Research was done in 23 villages of the Primary Health Centre, Anji, in Wardha District of Maharashtra. In February and March 2008, needs assessment was undertaken by interviewing the mothers of 261 children and 260 adolescent girls. Hemoglobin levels of adolescent girls and children were measured with the use of the hemoglobin color scale. The girls were given weekly iron-folic acid tablets, and the children were given daily liquid iron prophylaxis for 100 days in a year through community participation. The adolescent girls and the mothers of the children and adolescent girls were also given nutritional education on the benefits and side effects of iron supplementation. In June and July 2008, follow-up assessment was performed by survey and force field analysis. There was a significant reduction in the prevalence of nutritional anemia from 73.8% to 54.6% among the adolescent girls and from 78.2% to 64.2% among the children. There was improvement in awareness of iron-rich food items among the adolescent girls and the mothers of the children. The benefits to girls, such as increase in appetite and reduction in scanty menses, tiredness, and weakness, acted as positive factors leading to better compliance with weekly iron supplementation. The benefits to children perceived by the mothers, such as increase in appetite, weight gain, reduction in irritability, and reduction in mud-eating behavior, acted as a dominant positive force and generated demand for iron syrup.

Bullying among adolescents represents a major public health challenge. The aim of this study was to map the stability of bullying victimization across the transitional phase from lower to upper secondary school, and to describe the sociodemographic, academic and health-related characteristics of those bullied during the transition. 3674 Norwegian adolescents were followed longitudinally from the age of 15/16 until the age of 18/19, answering questionnaires about health, academic achievements, life events, lifestyle and sociodemography. The 337 participants reporting exposure to bullying victimization at age 15/16 were the target group, as we made comparisons between those reporting victimization only at the age of 15/16 (n=289) with the participants for whom the bullying had continued into later adolescence (n = 48). 14% of those victimized at age 15/16, reported continuation of bullying victimization into upper secondary school. These adolescents were significantly more likely to report having divorced parents, low parental educational level, poor self-perceived economy, muscle and skeletal pain, symptoms of mental distress, lower school marks in Norwegian and higher body-mass index (BMI) when group differences at age 18/19 were assessed through basic inferential statistical tests. However, the multivariate logistic regression analyses only revealed statistically significantly increased adjusted odds ratios for the variables mental distress and school-marks in Norwegian. The persistence of exposure to bullying from 10th grade to 13th grade is associated with mental health complaints and poor school performance. Preventive measures to take care of students being continuously bullied should be in place in secondary schools.

The prevalence of dental erosion is rising especially among children and adolescents and its grading needs further investigation. To determine the prevalence and severity of dental erosion in groups of Yemeni children and adolescents, and to clinically compare an erosion partial recording system (EPRS) with a proposed modified-simplified version (EPRS-M). Of 6163 individuals aged 5-6, 13-14 and 18-19 years, 911 were randomly selected, of which 668 participated in the study. Dental erosion was graded using EPRS. EPRS-M was proposed, and its sensitivity and specificity was calculated in relation to EPRS. Prevalence of erosion extending into dentine on at least one tooth was 6.8% among 5- to 6-year-olds, 3.0% among 13- to 14-year-olds and 14.6% among 18- to 19-year olds. The highest prevalence was 19.2% among girls aged 18-19 years which was significantly higher than boys (10.4%) in the same age group (P = 0.044). Sensitivity and specificity for EPRS-M in relation to EPRS were 85.7% and 100% for primary teeth, and 84.1% and 100% for permanent teeth. Dental erosion was common among children and older teenagers and highest among older girls but less common among younger teenagers. The tested accuracy of EPRS-M qualifies it to be used as an initial quick detection tool in future dental erosion research. © 2016 The Authors.

This study aimed to investigate the relationship between parental hypertension and cardiometabolic risk factors in adolescents. The authors analyzed data of 554 adolescents aged 13 to 19 years from the Korean National Health and Nutrition Examination Survey 2013. The associations between parental hypertension and cardiometabolic abnormalities in adolescents were evaluated through multivariate logistic regression. Parental hypertension was noted in 16.2% of participants. The adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for overweight (OR, 2.08; 95% CI, 1.01-4.28) and obesity (OR, 2.11; 95% CI, 1.09-4.07) were significantly higher in participants with parental hypertension. The adjusted ORs for abdominal obesity (OR, 2.36; 95% CI, 1.01-5.56), high blood pressure (OR, 3.05; 95% CI, 1.19-7.78), and elevated alanine transaminase defined as >35 IU/L (OR, 2.86; 95% CI, 1.03-7.95) were significantly higher in participants with parental hypertension. Prevention of cardiometabolic risk factors should be reinforced in the offspring of hypertensive parents. ©2017 Wiley Periodicals, Inc.

Objectives The aim of this retrospective cohort study was to examine whether exposure to early childhood protein-energy malnutrition (ECPEM) is related to worsened periodontal status in the permanent dentition during adolescence. Design A trained clinician/researcher examined the periodontal status of 96 persons aged 12–19 living in rural Haiti using WHO diagnostic criteria (Community Periodontal Index, WHO 1997). Malnutrition data of the study participants had been collected during the years 1988–1993 by a nongovernmental organization. We compared those who had been malnourished in early childhood, based on z-scores for anthropomorphic data collected during the first 5 years of life, with those who had not been malnourished, regarding mean Community Periodontal Index (CPI) score, controlling for age, sex, socioeconomic status, and smoking. Results Overall, 57.3% of the participants demonstrated a CPI score of 3 or greater in at least one sextant. ECPEM was independently and positively related to mean CPI score, when controlling for sex and smoking. Conclusions More than half of these young Haitians demonstrated CPI scores of 3 or greater, and ECPEM was related to poorer periodontal status, as measured by CPI, in the permanent dentition.

There is limited evidence on the effects of age and sex on intrinsic connectivity of networks underlying cognition during childhood and adolescence. Independent component analysis was conducted in 113 subjects aged 7-18; the default mode, executive control, anterior salience, basal ganglia, language and visuospatial networks were identified. The effect of age was examined with multiple regression, while sex and 'age × sex' interactions were assessed by dividing the sample according to age (7-12 and 13-18 years). As age increased, connectivity in the dorsal and ventral default mode network became more anterior and posterior, respectively, while in the executive control network, connectivity increased within frontoparietal regions. The basal ganglia network showed increased engagement of striatum, thalami and precuneus. The anterior salience network showed greater connectivity in frontal areas and anterior cingulate, and less connectivity of orbitofrontal, middle cingulate and temporoparietal regions. The language network presented increased connectivity of inferior frontal and decreased connectivity within the right middle frontal and left inferior parietal cortices. The visuospatial network showed greater engagement of inferior parietal and frontal cortices. No effect of sex, nor age by sex interactions was observed. These findings provide evidence of strengthening of cortico-cortical and cortico-subcortical networks across childhood and adolescence. Copyright © 2015 The Authors. Published by Elsevier Ltd..

Moksnes, Unni K; Haugan, Gørill

2018-03-01

Resilience is seen as a vital resource for coping and mental health in adolescents. However, there is no universally accepted theory or definition of resilience, leading to considerable challenges regarding how to operationalise and measure this construct. The study aimed at providing further knowledge of the psychometric properties (dimensionality, construct validity and internal consistency) of the 28-item version of the Resilience Scale for Adolescents (READ) in N = 1183 Norwegian adolescents, 13-18 years old. Dimensionality of READ was tested using confirmatory factor analysis (CFA). Convergent validity and reliability were tested using Pearson's correlation analysis, Cronbach's alpha and composite reliability. The CFA supported a modified, 20-item, five-factor structure with high reliability, supporting the dimensionality and internal consistency of the instrument. Convergent validity was confirmed where all factors correlated in expected directions with measures of sense of coherence, self-esteem, stress and depression. The psychometric properties of the READ need to be further evaluated in adolescents; however, the results indicate that a modified 20-item version of READ is adequate for assessing resilience in the present sample of Norwegian adolescents. © 2017 Nordic College of Caring Science.

2017-05-01

Our objective was to review international literature on suicidal behavior prevention for children under age 13. We gathered all relevant articles on suicide prevention for children under 13. We researched all publications in the French and English languages in PubMed (MEDLINE), PsychINFO and SUDOC databases published until February 2014, with the keywords "child", "child preschool", "prevention and control", "suicide", and "suicide attempted". Publications were included if they described suicidal behavior prevention programs (suicide prevention programs, attempted-suicide prevention programs, suicidal ideation screening programs), and if the studies concerned children under age 13. We also included references cited in the articles if they were not already present in our searches but met inclusion criteria. Studies were excluded if they analyzed populations of children and adolescents without sub-analysis for children under age 13. A total of 350 potentially relevant articles were identified, 33 of which met the inclusion criteria, including 4 retrieved from articles' bibliography. Preventive measures against suicidal behavior for children under 13 exist and include: social programs, maltreatment prevention, curriculum-based suicide prevention programs, suicide screening in schools, gatekeepers, reduction of access of lethal means of suicide, suicide screening by primary care, and post-suicide intervention programs. Overall, the evidence was limited by methodological concerns, particularly a lack of RCTs. However, positive effects were found: school-based suicide prevention programs and gatekeepers increased knowledge about suicide and how to seek help, post-suicide programs helped to reduce psychological distress in the short term. One study showed a decreased risk of attempted-suicide after entry into the child welfare system. There are promising interventions but there is not enough scientific evidence to support any efficient preventive measure against

2015-01-01

In the present study we examined how genotype-environment correlation processes differ as a function of adolescent age. We tested whether adolescent age moderates genetic and environmental influences on positivity and negativity in mother-adolescent and father-adolescent relationships using parallel samples of twin parents from the Twin and Offspring Study in Sweden and twin/sibling adolescents from the Nonshared Environment in Adolescent Development Study. We inferred differences in the role of passive and non-passive genotype-environment correlation based on biometric moderation findings. Findings indicated that non-passive rGE played a stronger role for positivity in mother- and father- adolescent relationships in families with older adolescents than families with younger adolescents, and that passive rGE played a stronger role for positivity in the mother-adolescent relationship in families with younger adolescents than in families with older adolescents. Implications of these findings for the timing and targeting of interventions on family relationships are discussed. PMID:25924807

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

Family conflict exacerbates the course of bipolar disorder (BP) among adults. However, few studies have examined family conflict among adolescents with BP, and fewer have looked at adolescent-reported and parent-reported family conflict separately. Subjects were 89 adolescents, aged 13 to 19 years, with a diagnosis of BP on the basis of the Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version (KSADS-PL). Subjects were divided into high-conflict and low-conflict groups using a median split on the Conflict Behavior Questionnaire (child report and parent report). The χ(2) analyses and independent samples t tests were performed for univariate analyses. Multivariable logistic regression analyses were performed on variables with P<0.2. Parent-reported and adolescent-reported Conflict Behavior Questionnaire scores were significantly correlated (r=0.50, P<0.001). High parent-reported family conflict was positively associated with recent manic symptoms, externalizing comorbidities, and dimensional scores reflecting emotional dysregulation. High adolescent-reported family conflict was positively associated with recent manic symptoms and emotional dysregulation, and negatively associated with socioeconomic status and lifetime psychiatric hospitalization. Bipolar subtype was significantly associated with high versus low family conflict. The limitations of this study included being a cross-sectional study, use of a medium-sized sample, and lack of a control group. Despite substantial agreement between adolescents and parents regarding the amount of family conflict, there were meaningful differences in the factors associated with adolescent-reported and parent-reported conflict. These findings demonstrate the importance of ascertaining family conflict from adolescents as well as from parents. Moreover, these findings can potentially inform family therapy, which is known to be effective for adolescents with BP.

Excessive adipocyte growth during the pubertal transition predisposes to the development and persistence of obesity in adulthood. Visceral accumulation of body fat is particularly disadvantageous when it is correlated with insulin resistance, secondary hyperinsulinaemia, dysglicaemia, and atherogenic dyslipidemia. The aim of this study was to conduct a nutritional status assessment and body composition analysis in 13-year-old adolescents of both genders with visceral fat accumulation (WC ≥ 90th percentile) and different BMI values. The evaluation of state of nutrition of 1,738 Polish boys (n = 882) and girls (n = 856) aged 13 was done based on anthropometric measurements and calculated BMI (body mass index), WC (waist circumference) and WHtR indices (waist-to-height ratio). Taking into consideration the value of WC ≥ 90 pc, 353 people were designated (20.3 % of the total) with visceral obesity (but with various BMI), whose body composition was examined by the method of bioelectric impedance analysis (BIA). A total of 249 adolescents of both sexes (70.5% of the selected, 102 boys and 147 girls) and their parents agreed to the study. In adolescents with visceral obesity a significant change of body content was ascertained depending on the value of the BMI. Even in the people with a proper value of the BMI, a significantly higher than standard increase of the percentage of total body fat (TBF) and decrease of both the percentage of body lean (BL) and the content of total body water (TBW) in the body was observed. The values of the BMI, WC and WHtR in adolescents were significantly correlated with each other as well as with TBF, BL and TBW, and the strength of correlation was dependent on sex. The state of nutrition in adolescents with visceral obesity, even with a proper BMI, might contribute to the development of a metabolic syndrome.

Abortion complications constitute 13% of maternal deaths worldwide and 40% of maternal deaths in Nigeria, while 80% of patients with abortion complications are adolescents. Assessing the adolescents' knowledge and attitude and the determinants of their sexual activities and contraceptive usage. This was a cross-sectional study conducted among high school students of Ogbomoso - a semi-urban settlement. Stratified multistage randomization was used to select one high school from each of five local government areas of the study site. Students were interviewed with pretested questionnaire to sought information on demographic status, family type, knowledge of sexuality, and contraceptive usages. The age range of the respondents was 10-19 years with mean±SD age 13.7±1.9 years. Among them, 6.5% were sexually active. Of the respondents, 56.8% scored good knowledge about sexuality and contraception and 57.5% respondents had good attitude to contraception. Age (p=0.004) and father's education (p=0.001) were factors associated with knowledge about sexuality and contraception, while mothers' occupation (p=0.02) and fathers' occupation (p=0.001) and education (p=0.04) were significantly associated with positive attitude toward contraception. This study revealed that a significant percentage of the studied adolescents had poor knowledge and attitude toward contraception, and many of the sexually active respondents had inaccurate knowledge on the use of contraceptives and where it could be obtained.

Abstract Objective: This study aimed to investigate the prevalence and factors associated with short sleep duration in adolescents from Maravilha – Santa Catarina (SC), southern Brazil. Methods: The sample consisted of 516 adolescents aged 10–19 years of both genders. Issues associated with short sleep duration and difficulty falling asleep, chronotype, daytime sleepiness, physical activity, sedentary behavior and weight status were investigated. Results: The prevalence of short sleep duration (<8h on school days) was 53.6%. Adolescents aged 17–19 years showed a 2.05-fold (95%CI: 1.20–3.50) greater prevalence of short sleep duration than those aged 10–12 years. The ones studying in morning and evening shifts had a higher prevalence of short sleep duration compared to those in the afternoon shift. Older age and school shift were the main factors associated with short sleep duration. Conclusions: Adolescents from Maravilha showed high prevalence of short sleep duration, and older adolescents that studied in the morning and evening shifts showed reduced sleep. PMID:26559604

Little is known about persistence of or recovery from chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) in adolescents. Previous studies have small sample sizes, short follow-up or have focused on fatigue rather than CFS/ME or, equivalently, chronic fatigue, which is disabling. This work aimed to describe the epidemiology and natural course of CFS/ME in adolescents aged 13-18 years. Longitudinal follow-up of adolescents enrolled in the Avon Longitudinal Study of Parents and Children. Avon, UK. We identified adolescents who had disabling fatigue of >6 months duration without a known cause at ages 13, 16 and 18 years. We use the term 'chronic disabling fatigue' (CDF) because CFS/ME was not verified by clinical diagnosis. We used multiple imputation to obtain unbiased estimates of prevalence and persistence. The estimated prevalence of CDF was 1.47% (95% CI 1.05% to 1.89%) at age 13, 2.22% (1.67% to 2.78%) at age 16 and 2.99% (2.24% to 3.75%) at age 18. Among adolescents with CDF of 6 months duration at 13 years 75.3% (64.0% to 86.6%) were not classified as such at age 16. Similar change was observed between 16 and 18 years (75.0% (62.8% to 87.2%)). Of those with CDF at age 13, 8.02% (0.61% to 15.4%) presented with CDF throughout the duration of adolescence. The prevalence of CDF lasting 6 months or longer (a proxy for clinically diagnosed CFS/ME) increases from 13 to 18 years. However, persistent CDF is rare in adolescents, with approximately 75% recovering after 2-3 years. Published by the BMJ Publishing Group Limited.

2011-02-01

This study longitudinally investigated spillover effects of conflict resolution styles in adolescent-parent relationships and adolescent friendships. Questionnaires about conflict resolution styles with parents and best friends were completed by adolescents from two age cohorts: 559 early adolescents (mean age 13.4) and 327 middle adolescents (mean age 17.7). Path analyses on two waves, with a three-year interval, indicated that in the early-to-middle adolescent group positive problem solving and conflict engagement spilled over from adolescent-parent relationships to adolescent friendships and not from adolescent friendships to adolescent-parent relationships. In the middle-to-late adolescent group, we found bidirectional spillover effects for these two conflict resolution styles. For withdrawal, we found bidirectional spillover effects in both cohorts. This study showed that both parents and friends set the stage for exercising and learning conflict resolution styles and thereby shape adolescents' future conflict behavior.

Social anxiety is a common psychological disorder that often emerges during adolescence and is associated with significant impairment. Efforts to prevent social anxiety disorder require sound assessment measures for identifying anxious youth, especially those from minority backgrounds. We examined the factorial invariance and latent mean differences of the Social Anxiety Scale for Adolescents (SAS-A) across gender and age groups in Hispanic American adolescents (N = 1,191; 56% girls; 15-18 years) using multigroup confirmatory factor analyses. Results indicated that the factorial configuration of the correlated three-factor model of the SAS-A was invariant across gender and age. Analyses of latent mean differences revealed that boys exhibited higher structured means than girls on the Social Avoidance and Distress-General (SAD-General) subscale. On all SAS-A subscales, Fear of Negative Evaluation, Social Avoidance and Distress-New, and SAD-General, estimates of the structured means decreased with adolescent age. Implications for further research and clinical practice are discussed. © The Author(s) 2014.

Our objective was to analyze differences in clinical characteristics and comorbidity between different types of adolescent depressive disorders. A sample of 218 consecutive adolescent (ages 13-19 years) psychiatric outpatients with depressive disorders was interviewed for DSM-IV Axis I and Axis II diagnoses. We obtained data by interviewing the adolescents themselves and collecting additional background information from the clinical records. Lifetime age of onset for depression, current episode duration, frequency of suicidal behavior, psychosocial impairment, and the number of current comorbid psychiatric disorders varied between adolescent depressive disorder categories. The type of co-occurring disorder was mainly consistent across depressive disorders. Minor depression and dysthymia (DY) presented as milder depressions, whereas bipolar depression (BPD) and double depression [DD; i.e., DY with superimposed major depressive disorder (MDD)] appeared as especially severe conditions. Only earlier lifetime onset distinguished recurrent MDD from first-episode MDD, and newly emergent MDD appeared to be as impairing as recurrent MDD. Adolescent depressive disorder categories differ in many clinically relevant aspects, with most differences reflecting a continuum of depression severity. Identification of bipolarity and the subgroup with DD seems especially warranted. First episode MDD should be considered as severe a disorder as recurring MDD. (c) 2006 Wiley-Liss, Inc.

In recent decades, diets have changed rapidly in the Kingdom of Saudi Arabia (KSA) because the Western diet is replacing the traditional Arabic diet. This has resulted in an alarming increase in the number of overweight and obese children and adolescents in KSA. It is well documented that lifestyle is strongly associated with the development of obesity. Nevertheless, this remains to be demonstrated in adolescents from a rapidly developing country in the Middle East such as Saudi Arabia. This study tested the hypothesis that the new current dietary habits are related to the increase in overweight and obese Saudi Arabian adolescents. In 2006, a cross-sectional study was conducted among 239 adolescents (13-18 years old) who were selected by cluster sampling from schools in Jeddah, KSA. The nutritional status was assessed by anthropometric and biochemical parameters at the Saudi German Hospitals Group, Jeddah. Dietary habits were evaluated by a 3-day dietary recall (food diary) and a food frequency questionnaire. The mean age of the participants was 15.5 ± 2.5 years. The mean body mass index was 27.43 ± 4.61 kg/m(2). A total of 44.6% of the adolescents were overweight, and 56.6%, 30.5%, and 13.0% of energy was derived from carbohydrates, fats, and proteins, respectively. Compared with the Dietary Reference Intake, carbohydrate and fat intakes were higher, and calcium, iron, and zinc intakes were lower. Higher cholesterol and lower hemoglobin levels were found in 30.5% and 53.6% of the adolescents, respectively. In summary, increased weight status of 13- to 18-year-old Saudi adolescents was related to their inadequate dietary habits. This indicates the importance of rapidly promoting a healthier lifestyle among Saudi Arabian adolescents. Copyright © 2010 Elsevier Inc. All rights reserved.

Recent studies have shown that adolescents have initiated their sex lives earlier and earlier, without, however, receiving consistent sex education. The objectives of this study were to analyze the sexual behavior of adolescent high school students and identify the habits of sexual health in sexually active adolescent high school students. An exploratory study was conducted with 680 adolescents, whose age ranged between 15 and 19 years. Results showed that most participants had not initiated their sex life; boys are those who most report having had sexual relations; not all the interviewed adolescents used condoms during sex; most adolescents do not practice sexual health surveillance. It is important for sexually active adolescents to receive health care and counseling. Health institutions and their workers must be proactive in trying to approach adolescents.

Identifying early pre-teen predictors of adolescent weight gain and the development of impaired fasting glucose (IFG) and type 2 diabetes (T2DM) at age 18-19 y could provide avenues for prevention. We evaluated possible pre-teen predictors for development of IFG, T2DM, and changes in body mass index at age 18-19 y in black and white girls. In a prospective cohort study, body habitus and fasting insulin and glucose were measured at ages 9-10 and 18-19 y, and multiple 3-d diet records were collected. Factors predicting 10-y change in body mass index and development of IFG and T2DM together were assessed. In multivariate analyses, 10-y change in homeostatic model assessment of insulin resistance (HOMA-IR) and the age 9-10 y HOMA-IR x percentage of calories from fat interaction were positive predictors of 10-y changes in body mass index. At age 18-19 y, there were 5 incident cases of T2DM, 37 cases of IFG, and 597 noncases. Age 9-10 y IFG and HOMA-IR (or insulin), 10-y change in HOMA-IR (or insulin), and the age 9-10 y insulin x total caloric intake interaction predicted IFG and T2DM at age 18-19 y. Pre-teen IFG, insulin resistance (and insulin), and rapidly increasing insulin resistance during adolescence identifies girls who are at greater risk of future IFG and T2DM. In addition, insulin resistance, interacting with high-fat diets, identifies girls who are at risk of greater weight gain. These findings could open avenues to primary prevention of obesity, IFG, and T2DM in children.

The aim of the present study was to investigate whether executive functioning (EF) in early adolescence predicted alcohol use disorder (AUD) in late adolescence and whether adolescents with AUD differed in maturation of EF from controls without a diagnosis. We used the data from the Tracking Adolescents' Individual Lives Survey (TRAILS), a cohort of 2230 Dutch adolescents. Working memory, inhibition, and attention were measured at ages 11 and 19. At age 19, lifetime DSM-IV diagnoses were determined, resulting in a control group (n = 1111) and two AUD groups, i.e., alcohol abusers (n = 381) and alcohol dependents (n = 51). Regression analyses assessed whether EF at age 11 predicted the transition to AUD in late adolescence and whether AUD affected maturation of EF from age 11 to 19. EF in early adolescence did not predict AUD in late adolescence. A significant interaction effect emerged between gender and alcohol dependence for shift attention (β = 0.12, SE=0.36), with girls showing smaller maturational rates. This effect remained significant after controlling for alcohol intake (ages 16 and 19) and comorbid psychiatric disorders. Our results do not replicate the finding that EF in early adolescence is a significant predictor of AUD in late adolescence. Furthermore, for the majority of tasks, adolescents with AUD do not differ in EF maturation over the course of adolescence. Alcohol dependent girls however, show less maturation of shift attention. This is independent of the quantity of alcohol intake, which could suggest that non-normative maturation of EF is associated with the behavioural components of AUD. Copyright © 2016 Elsevier Ltd.

Online usage of theory of mind continues to develop in late adolescence.

Dumontheil, Iroise; Apperly, Ian A; Blakemore, Sarah-Jayne

2010-03-01

The development of theory of mind use was investigated by giving a computerized task to 177 female participants divided into five age groups: Child I (7.3-9.7 years); Child II (9.8-11.4); Adolescent I (11.5-13.9); Adolescent II (14.0-17.7); Adults (19.1-27.5). Participants viewed a set of shelves containing objects, which they were instructed to move by a 'director' who could see some but not all of the objects. Correct interpretation of critical instructions required participants to use the director's perspective and only move objects that the director could see. In a control condition, participants were asked to ignore objects in slots with a grey background. Accuracy improved similarly in both conditions between Child I and Adolescent II. However, while performance of the Adolescent II and Adult groups did not differ in the control condition, the Adolescent II group made more errors than the adults in the experimental condition. These results suggest that theory of mind use improves between late adolescence and adulthood. Thus, while theory of mind tasks are passed by age 4, these data indicate that the interaction between theory of mind and executive functions continues to develop in late adolescence.

2005-08-01

To examine whether first-episode psychosis patients with onset during adolescence (ages 15-18) differ significantly from those with young-adult onset (ages 19-30). Consecutive patients presenting with first-episode psychosis (N = 242) were assessed for demographic and illness characteristics such as duration of untreated psychosis, diagnosis, length of prodromal period, premorbid adjustment, level of psychotic, negative, depressive, anxiety, and extrapyramidal symptoms, and alcohol and drug use. Eighty-two patients (40.8%) had an onset of psychosis during adolescence (ages 15-18) and 119 (59.2%) during young adulthood (ages 19-30). The adolescent-onset group experienced longer delays in treatment of psychosis (duration of untreated psychosis) (p < .02), showed modestly worse premorbid functioning during late adolescence (p < .05), and were more likely to present with bizarre behavior (p < .01) and primary negative symptoms (p < .01). Patients with adolescent onset of psychosis are more likely to present with clinical characteristics that portend a poorer outcome and may require a different approach to early identification and treatment.

The present study investigated associations in gender dyads of parents' and adolescents' time spent on television and video viewing (TV/DVD), and computer and electronic game use (PC/games) at the ages of 11 and 13 years. Possible mediating effects of parental modelling and parental regulation in the relationship between parental education and adolescents' prospective TV/DVD and PC/game time were further examined. A total of 908 adolescents, participating at both ages 11 and 13 years in the Norwegian HEalth In Adolescents (HEIA) cohort study (2007-2009), were included in the analyses. Data on adolescents', mothers' and fathers' self reported time spent on TV/DVD and PC/games were measured at both time points by questionnaires. Correlation coefficients were used to examine gender dyads of parents' and adolescents' reports. Mediation analyses using linear regression investigated possible mediation effects of parental modelling and parental regulation in the prospective relationship between parental education and adolescents' time spent on TV/DVD and PC/games between the ages of 11 and 13 years. Correlations of screen time behaviours in gender dyads of parents and adolescents showed significant associations in time spent on TV/DVD at the age of 11 and 13 years. Associations between mothers and sons and between fathers and daughters were also observed in time spent on PC/games at the age of 11 years. Maternal and paternal modelling was further found to mediate the relationship between parental education and adolescents' prospective TV/DVD time between the ages of 11 and 13 years. No mediation effect was observed for parental regulation, however a decrease in both maternal and paternal regulation at the age of 11 years significantly predicted more TV/DVD time among adolescents at the age of 13 years. Cross-sectional and longitudinal relationships were observed in gender dyads of parents' and adolescents' screen time behaviours at the ages of 11 and 13 years, and further

Despite the harmful effects of cigarette smoking, this habit in asthmatic adolescents continues to be a health problem worldwide. Our objectives were to determine the epidemiological profile of smoking and the degree of nicotine dependence among asthmatic adolescents. Through a cross-sectional investigation, 3383 adolescents (13-19 years of age) were studied. Information was collected using a previously validated questionnaire. Two study groups of adolescent smokers were formed: one composed of asthmatic adolescents and the other of healthy youths. Asthmatic adolescents were found to be more likely to smoke (21.6% vs 11.8%) and to have some degree of nicotine dependence compared with healthy adolescents (51.6% vs 48.8%). The most important characteristic of smoking in asthmatic adolescents was found to be an onset before 11 years of age due to curiosity about cigarettes. Asthmatic youths continue smoking because this habit decreases their anxiety and stress. Adolescents know that smoking is addictive and often smoke on waking up in the morning or when they are sick. Yet, these adolescents do not consider smoking to be a problem. In this study, curiosity about cigarettes was the primary reason why asthmatic adolescents smoked for the first time and developed a greater dependence to nicotine compared with healthy adolescents. Moreover, the findings show that many of the factors that favour the development of smoking are preventable, given that they are present in the family and social environment.

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

2015-01-01

Objective: To assess the impact of acanthosis nigricans (AN) on depression symptoms, related quality of life and self-esteem scores in obese adolescent girls. Methods: Fifty-nine obese adolescent girls (mean age: 13.19±1.3 years, age range: 12-17 years, mean body mass index: 29.89±3.30) were enrolled in this study. The obese adolescent girls were divided into two groups based on presence or absence of AN. Non-obese healthy adolescents constituted the control group (30 girls, mean age: 13.5±1.4 years). All subjects were evaluated using the Children’s Depression Inventory (CDI), the State-Trait Anxiety Inventory for Children (STAI-C), and the modified Rosenberg Self-Esteem Scale (SES). Higher scores indicated more severe depression and anxiety, as well as low self-esteem status. Results: The AN and non-AN obese groups showed significantly higher CDI, STAI-C and SES scores than the control group, and the two obese groups demonstrated no significant differences for these scores. The AN obese group with higher total testosterone levels (>50 ng/dL) had higher scores for SES (2.55±1.8 vs. 1.42±1.2; p=0.03) than the AN obese group with low total testosterone levels. SES scores significantly correlated with total testosterone levels (r=0.362; p=0.03) and fasting insulin (r=0.462; p=0.03) in the AN obese group. Conclusion: Higher SES scores (low self-esteem status) were determined in obese adolescents with acanthosis and were related to hyperandrogenism. This study also showed that a high testosterone level may be one of the important indicators of low self-esteem status in obese girls with AN. PMID:25800478

Objective To examine whether firearms are more frequently stored loaded, unlocked, or both in households with adolescents only (aged 13-17 years) compared with households with younger children only (aged 0-12 years). Design Random-digit-dial survey on firearms (n=2770). We computed bivariate associations between the presence of adolescents and firearm storage practices. Statistical significance was assessed using prevalence ratios with 95% confidence intervals. Setting United States. Participants Survey respondents with children (aged <18 years) who reported the presence of a household firearm. Main Outcome Measures Prevalence of firearms in the home stored loaded and/or unlocked. Results Of the 392 respondents, 22% had a loaded firearm, 32% had an unlocked firearm, and 8% had a firearm stored loaded and unlocked. Compared with households with younger children, households with adolescents only were somewhat more likely to store a firearm unlocked (42% vs 29%; prevalence ratio, 1.48; 95% confidence interval, 1.04-2.02), loaded (26% vs 20%; prevalence ratio, 1.25; 95% confidence interval, 0.82-1.91), or both (10% vs 8%; prevalence ratio, 1.43; 95% confidence interval, 0.64-3.19). Conclusions Parents of adolescents appear to be more likely to keep household firearms stored unsafely, especially with regard to keeping firearms unlocked. This is of concern because most youth firearm injuries happen to adolescents. Firearm injury prevention programs should directly target parents of adolescents to promote safe firearm storage.

To compare the family functioning profile (FFP) in adolescents addicted to drugs and those not addicted to drugs. Cross-sectional study comparative. A high school in Querétaro State, Mexico. Study of 63 adolescents with and without addiction, of both sexes between the ages of 13 and 19, enrolled in high school; two groups formed, one not addicted to drugs (systematic probabilistic sampling was carried out); and compared with drug addicts (database). FFP(Alpha Cronbach 91). Descriptive and inferential statistical analysis. Adolescents with drug addiction (n=20), average age 17.5±0.4 (range 16-19), and group of non-addicts (n=43), average age 16.9±0.1 (range 15-18) and P=0.000. All the adolescents lived in an urban area with a predominantly simple nuclear modern, working family type. Half (50%) of addicted adolescents came from broken families P=0.002. The dispersion phase was a protective factor in preventing drug addiction in adolescents (P=0.003 OR 0.6 95% Cl;1.8-21.0). Significant statistical differences were observed in authority (OR=29.7, 95% Cl; 5.8-150.5), supervision (OR 10.3, 95% Cl; 2.8-37.2) and support (OR 0.04, 95% Cl; 5.5-109.8). The overall family dysfunctionality, (P=0.000, OR 1.8, 95% Cl; 1.3-2.3). Dysfunctional families are a risk factor for drug addiction in adolescents, when there is insufficient authority and supervision within the family. On the other hand, family support, as well as the dispersion phase, are protective factors. Copyright © 2010 Elsevier España, S.L. All rights reserved.

Few studies have examined the adolescents' depression in low-income countries and no research has yet been carried out in Bangladesh. This study estimated the prevalence of depressive symptoms and explored the associated factors and help seeking behavior among adolescents in Bangladesh. Data originated from a cross section of 2,440 randomly selected boys and girls aged 13-19 years in a rural district and urban slums of Dhaka city, Bangladesh, during October-November 2012. Beck Depression Inventory (BDI), a 21-item scale, measured the prevalence of depressive symptoms using a cut-off 16 or higher. The prevalence of depressive symptoms among adolescents was 14%, with predominance in urban slums and among girls. Older age (15-19 years), poverty, and poor parental relation were found to be associated with depressive symptoms of both sexes; family history of depressive symptoms for boys; and reproductive illness and sexual abuse for girls. More than 80% of depressed adolescents sought no help. Adolescent depressive symptoms are common and largely undetected public health problem in Bangladesh. Policies aimed at concerted efforts for implementing a school-based counseling program with components of cognitive behavioral therapy and developing referral systems for those who scored at least 30 at BDI may ameliorate the potential harmful consequences of depressive symptoms in adolescents. © 2016 Wiley Periodicals, Inc.

Background/Objective: The objective of the study was to provide current estimates of the prevalence and trends of overweight and obesity (OW+OB) in Mexican children and adolescents. Subjects/Methods: Body mass index objectively measured was analyzed for 37 147 children and adolescents aged 0–19 years obtained in 2012 as part of the National Health and Nutrition Survey (ENSANUT-2012), a nationally representative sample of the Mexican population. In addition, data from previous National Nutrition Surveys obtained in 1988, 1999 and 2006 were compared with analyze trends over a 24-year period (1988–2012) for children <5 years of age and adolescents and over a 13-year period (1999–2012) for school-age children. World Health Organization Child Growth Standard was used to define OW+OB. Results: In 2012, 33.5% of children <5 years of age (both sexes) were at risk of overweight or were overweight (OW); 32% and 36.9% of girls and boys 5–11 years of age were OW+OB, respectively, and 35.8% and 34.1% of female and male adolescents were OW+OB, respectively. Statistically significant trends were documented for all age groups during the study period. Overall change in the combined prevalence in preschool children was 6.3±1.0 percentage points (pp; P<0.001; 0.26 pp per year) in the last 24 years, showing the highest increase between 1988 and 1999, whereas for school-age girls (from 1999 to 2012) and adolescent females (from 1988 to 2012), OW+OB increased across all periods at a declining trend, with an overall change of 0.5 and 1.0 pp per year, respectively. Changes in the prevalence of OW+OB were highest among children and adolescents in the lowest quintile of the household living condition index. Conclusions: Prevalence of OW+OB among children and adolescents increased significantly during the last 13–24 years. The rate of increase has declined in the last 6 years in all age groups. Changes in prevalence of OW+OB presented here suggest that, in Mexico, the burden of

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

American Indian and Alaska Native (AIAN) adolescents use tobacco at earlier ages and in larger quantities compared to non-AIAN peers. Regular tobacco use was examined against five protective factors (peer networks supportive of not using drugs, college aspirations, team sports, playing music, and volunteerism). Participants consisted of 112 adolescents between the ages of 13 and 19 who participated in a study testing the efficacy of a life-skills program aimed at reducing substance-related consequences. Findings indicated that, with the exception of prosocial peer networks and volunteerism, each of the above factors was significantly associated with a reduced probability of being a regular tobacco user. Gender differences were notable. These results hold important treatment implications regarding the reduction and prevention of tobacco use among AIAN youth.

Patient-centered health care recognizes that adolescents and parents are stakeholders in adolescent health. We investigate adolescent and parent interest in receiving information about health topics and parent-teen communication from clinicians. Ninety-one parent-adolescent dyads in one practice completed individual interviews. Items assessed levels of interest in receiving health and health communication information from the adolescent's doctor about 18 topics, including routine, mental health, sexual health, substance use, and injury prevention issues. Analyses tested differences between parents and adolescents, within-dyad correlations, and associations with adolescent gender and age. Most parents were female (84%). Adolescents were evenly divided by gender; 36 were aged 12-13 years, 35 were aged 14-15 years, and 20 were aged 16-17 years. Adolescent race reflected the practice population (60% black; 35% white). The vast majority of parents and adolescents reported moderate or high levels of interest in receiving information about all 18 health issues and information to increase parent-teen communication about these topics. Parents' interest in receiving information varied by adolescent age when the expected salience of topics varied by age (e.g., acne, driving safety), whereas adolescents reported similar interest regardless of age. Adolescent gender influenced parent and adolescent interest. Level of interest in receiving information from doctors within adolescent-parent pairs was not significantly correlated for one-half of topics. Parents and adolescents want health care professionals to help them learn and talk about a wide range of adolescent health topics. Feasible primary care interventions that effectively improve parent-teen health communication, and specific adolescent health outcomes are needed.

Dental malocclusion is a highly prevalent health condition in adolescence. Patients seek treatment primarily for aesthetic reasons. Therapy benefits are regarded, in the first place, to be psychosocial in nature. Therefore, it is mandatory to consider the perspective of the patient in treatment planning and control using a dental-aesthetics-related quality of life measure. The objective of this study was to investigate whether the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) developed in adult samples including the subscales Dental Self-Confidence, Social Impact, Psychological Impact and Aesthetic Concern is also applicable in adolescents aged 11 years and above. The psychometric properties were examined across three age-groups (11-12, 13-14, 15-17 year olds) with respect to factorial invariance, internal consistency, temporal stability, discriminant validity and gender- or age-associated scale mean differences and item response bias. Participants were 1,112 adolescents recruited from 4 institutions: orthodontic and dental practices, schools, and youth clubs. They answered the 23 partially reformulated items of the PIDAQ. Subjective and dentist evaluations of dental occlusion were assessed using the Perception of Occlusion Scale and the Aesthetic Component of the Index of Orthodontic Treatment Need. Both indices were aggregated to one Malocclusion Index (MI-S and MI-D). The fit indices using confirmatory factor analyses suggested that the factor structure and factor loadings underlying the PIDAQ items were invariant across ages (comparative fit index = 0.91, root-mean-square error of approximation = 0.04). Internal consistency and temporal stability were adequate within the age-groupings (Alpha = 0.71-0.88; intra-class correlations = 0.82-0.96). Adolescents with severe compared to slight malocclusion according to both self-evaluation and dentist evaluation were found to differ in all PIDAQ subscales at a level of p < 0.001 for all ages.

Asthma is associated with diminished health-related quality of life (HRQoL). Particularly in adolescence, asthma may be under-diagnosed and undertreated or poorly managed. Therefore, we aimed to determine the association between childhood wheezing phenotypes rather than asthma and adolescent HRQoL in children aged 10-17 yr. We analyzed the data from two prospective population-based cohort studies (n = 604 and n = 1804) conducted in southern Germany with baseline assessments in 2000 and 2006 and follow-ups at frequent intervals. Parent-reported wheeze was categorized into never, early transient, persistent, and late-onset wheeze. We assessed child-reported HRQoL in seven scales using the validated KINDL-R. Multivariate linear regression models were computed. Participants with late-onset wheeze had significantly lower values in all HRQoL scales, but physical well-being compared to never wheezers. Early transient wheeze was negatively associated with three HRQoL scales only (family, school, and total). These effects were confined to the oldest age group (≥13.5 yr) in one study. Persistent wheeze was not associated with HRQoL. In teenagers, late-onset wheezers seem to be particularly vulnerable for impairments in psychosocial aspects of health-related quality of life. They may therefore require particular attention with regard to education about asthma management and potentially family-based psychosocial intervention. © 2014 John Wiley & Sons A/S.

Injuries and violence among young people have a substantial emotional, physical, and economic toll on society. Understanding the epidemiology of this public health problem can guide prevention efforts, help identify and reduce risk factors, and promote protective factors. We examined fatal and nonfatal unintentional injuries, injuries intentionally inflicted by other (i.e., assaults and homicides) among children ages 0-19, and intentionally self-inflicted injuries (i.e., self-harm and suicides) among children ages 10-19. We accessed deaths (1999-2015) and visits to emergency departments (2001-2015) for these age groups through the Centers for Disease Control and Prevention's (CDC) Web-based Injury Statistics Query and Reporting System (WISQARS), and examined trends and differences by age, sex, race/ethnicity, rural/urban status, and injury mechanism. Almost 13,000 children and adolescents age 0-19 years died in 2015 from injury and violence compared to over 17,000 in 1999. While the overall number of deaths has decreased over time, there were increases in death rates among certain age groups for some categories of unintentional injury and for suicides. The leading causes of injury varied by age group. Our results indicate that efforts to reduce injuries to children and adolescents should consider cause, intent, age, sex, race, and regional factors to assure that prevention resources are directed at those at greatest risk.

Summary Added sugar intake during adolescence has been associated with weight gain and cardiometabolic risk factors. Moreover, dietary habits may persist into adulthood, increasing chronic disease risk in later life. This systematic review investigated changes in intake of added sugars between the ages of 13 and 30 years. Literature databases were searched for longitudinal studies of diet during adolescence or early adulthood. Retrieved articles were screened for studies including multiple measures of intake of sugars or sugary foods from cohort participants between the ages of 13 and 30. Data were analysed using random‐effects meta‐analysis, by the three main nutrient and food group categories identified (PROSPERO: CRD42015030126). Twenty‐four papers reported longitudinal data on intake of added sugar or sucrose (n = 6), sugar‐sweetened beverages (SSBs) (n = 20) and/or confectionery (n = 9). Meta‐analysis showed a non‐significant per year of age decrease in added sugar or sucrose intake (−0.15% total energy intake (95%CI −0.41; 0.12)), a decrease in confectionery consumption (−0.20 servings/week (95%CI −0.41; −0.001)) and a non‐significant decrease in SSB consumption (−0.15 servings/week (95%CI −0.32; 0.02)). Taken together, the overall decrease in added sugar intake observed from adolescence to early adulthood may suggest opportunities for intervention to further improve dietary choices within this age range.

2018-05-01

The aim of this study was to summarize recent evidence on the global epidemiology of adolescents (age 10-19 years) living with HIV (ALHIV), the burden of HIV on the health of adolescents and HIV-associated mortality. In 2016, there were an estimated 2.1 million (uncertainty bound 1.4-2.7 million) ALHIV; 770 000 younger (age 10-14 years) and 1.03 million older (age 15-19 years) ALHIV, 84% living in sub-Saharan Africa. The population of ALHIV is increasing, as more peri/postnatally infected ALHIV survive into older ages; an estimated 35% of older female ALHIV were peri/postnatally infected, compared with 57% of older male ALHIV. Although the numbers of younger ALHIV deaths are declining, deaths among older ALHIV have remained static since peaking in 2012. In 2015, HIV-associated mortality was the eighth leading cause of adolescent death globally and the fourth leading cause in African low and middle-income countries. Needed investments into characterizing and improving adolescent HIV-related health outcomes include strengthening systems for nationally and globally disaggregated data by age, sex and mode of infection; collecting more granular data within routine programmes to identify structural, social and mental health challenges to accessing testing and care; and prioritizing viral load monitoring and adolescent-focused differentiated models of care.

Rare reports can be found about sex- and age-specific body composition survey among Chinese population. The aim of this study is to explore the change of sex-specific body compositions with aging among Chinese adolescents, adults and elders. In a large-scale population survey about physiological constants and health conditions, 75,714 subjects who aged from 8 to 80 completed body composition array. Body mass index (BMI), percentage body fat (PBF), water percentage of body weight (WPBW), water percentage of lean body mass (WPLBM), fat-free mass index (FFMI) and basic metabolic rate were examined with Biodynamics BI-310 body composition analyzer. General obesity is defined as BMI equal to or greater than 28 kg/m2. The prevalence rates of general obesity were 9.4% for males and 7.7% for females respectively. With aging, PBF and FMI showed a U-shape curvilinear trend and WPBW showed a parabolic trend for males. At same age group: 18-19 age groups, PBF and FMI declined to the valley and WPBW rose to the peak. For females, PBF, WPBW and FMI changed in a linear trend. The values of WPLBM and FFMI showed same curvilinear trend for two genders. WPLBM changed in a U-shape trend and touched the valley in twenties for males and in 18-19 age groups for females. The value of FFMI was larger for older age groups in the younger generation but smaller in the older generation. A parabolic trend peaking was seen in the thirties for males and in the forties for females. Regression models with age as independent variable showed that the larger rate of increase of PBF and smaller rates of increase for WPBM and WPLBM with aging for males. This study presents detailed data about sex-specific body composition conditions. Different change trend with aging was found about body composition conditions.

The Goal-corrected Partnership Adolescent Coding System (GPACS) has shown promise in assessing a secure as well as three atypical patterns of parent-adolescent interaction during a conflict discussion. The current study of 186 economically disadvantaged families examines the degree to which four GPACS patterns: Secure/Collaborative, Punitive, Role Confused and Disoriented—account for residual change in adolescents’ social competence and maladaptive behavior (internalizing, externalizing, and risk behaviors) between ages 13 to 15. Adolescents from Secure/Collaborative dyads at age 13 were more likely to have a secure state of mind in the AAI at age 15 and showed increases in teachers’ ratings of empathy and decreases in teachers’ ratings of externalizing behaviors between ages 13 and 15. Adolescents in Disoriented dyads showed a dramatic increase in teacher-rated internalizing problems, while male adolescents in Role Confused dyads reported increased involvement in risk behaviors including unprotected sexual activity and substance use problems.

Iodine is an important element for the synthesis of thyroid hormone, and its deficiency or excessive intake is associated with various thyroid diseases. Little is known about the association between iodine status and thyroid function among children and adolescents living in iodine-rich areas. Therefore, this study analyzed this association using data from a nationwide survey. From the Korea National Health and Nutrition Examination Surveys VI (2013-2015) data, 1288 subjects (711 male) aged 6-19 years who underwent a urinary iodine concentration (UIC) test and 1000 subjects (564 male) aged 10-19 years who underwent a thyroid function test were included in this study. Serum levels of thyrotropin (TSH), free thyroxine (fT4), and thyroperoxidase antibodies (TPOAb) were analyzed. Subclinical hypothyroidism (SCH) was defined as TSH >5.5 μIU/mL with a normal fT4 level. Median daily iodine intake was calculated from the UIC. Daily sodium intake was derived from the nutritional survey data of 1181 subjects. The median UIC was 449 μg/L (range 15-21,905 μg/L), and the prevalence rates of UIC ≥300 μg/L and ≥1000 μg/L were 64.9% and 25.0%, respectively. The prevalence rates of a sodium intake >2000 mg/day and iodine intake >2400 μg/day were 75.0% (885/1181) and 12.7% (164/1288), respectively. The prevalence rates of SCH and TPOAb >34 IU/mL were 7.2% (72/1000) and 2.3% (23/1000), respectively. The prevalence of SCH was significantly higher in the iodine deficient and iodine excess groups compared to those in the UIC 100-299.9 μg/L group (p = 0.038). Therefore, there was a U-shaped and inverted U-shaped correlation between serum levels of TSH and fT4 with UIC, respectively. These correlations were especially prominent when UIC was >1000 μg/L. There was no definite correlation between TPOAb and UIC. Excess iodine was prevalent in Korean children and adolescents, and it may be associated with SCH. Therefore, monitoring the iodine status and

ABSTRACT Objective: To analyze the association between perceived stress in adolescence, body weight and romantic relationships. Methods: Participants were 2,571 adolescents (56.1% female), with mean age of 16.6±1.2 years, who were students of public schools in Amazonas. The adolescents answered a questionnaire with sociodemographic questions (sex, age group, school year, study shift, maternal schooling and family income) and related to body weight dissatisfaction, romantic relationships (identified by the relationship status - with or without a partner) and perceived stress (dependent variable). Binary Logistic Regression was used to test the association between perceived stress, body weight dissatisfaction and romantic relationships. The analysis was adjusted by sex and age group. Results: The prevalence of perceived stress was 19.0% (95% confidence interval - 95%CI 17.5-20.3), and was higher among girls (23.2%; 95%CI 21.5-24.5) than boys (13.6%; 95%CI 12.2-14.7). Adolescents with partners (OR 1.76; 95%CI 1.14-2.71) and those who wanted to lose body weight (OR 1.53; 95%IC 1.18-1.98) were more likely to perceive themselves as stressed. Conclusions: There was an association between perceived stress, relationship status and body weight dissatisfaction. Regardless of sex and age group, the adolescents with a partner and those who wanted to lose weight were more likely to perceive themselves as stressed. Girls should receive special attention, as well as adolescents with partners and those who want to lose body weight. PMID:28977133

Since adolescence obesity is becoming an international concern, our objective was to evaluate obesity-related behavior in Lebanese adolescents. We performed a cross-sectional study in 19 Lebanese private schools, using a random multistage cluster sampling process. Dietary and physical activity behaviors were assessed in 1933 adolescents aged 12 to 18 years, stressing on differences between boys and girls and obesity categories. We found that boys were more obese than girls (72% versus 3.7% ; p < 0.001); they were less likely to adopt dietary behaviors that maintain or increase weight, such as eating lighter food (13.1% versus 20.9% ; p < 0.001). However, girls were less likely to perform physical activity (81% versus 71%; p < 0.001). Our results are similar to those of other researchers. In this sample of Lebanese adolescents, dietary and physical activity behaviors differed between boys and girls ; these differences could explain their obesity rates. Educational and participative scholar interventions are necessary to induce changes in adolescents' behavior, stressing on physical activity for girls and healthier eating for boys.

To know the degree of metabolic control and prevalence of cardiovascular risk factors in T1D patients. Retrospective study including patients under 19 years of age with T1D controlled at a Chilean hospital in 2011. 94 patients were evaluated (average age at diagnosis: 7.3 years; current age: 11,9 years; evolution time: 4.5 years). Seventy-nine percent (79.8%) of patients presented glycated hemoglobin (HbA1c) over the recommended level with an average of 8.9%. The group between 13 and 19 years of age exhibited the worst metabolic control (86% with HbA1c abnormal levels). Overweight or obesity occurred in 26.6% of patients, 20.3% had LDL >100mg/dl and 4.2% had hypertension. Only about twenty percent of patients had adequate metabolic control as measured by HbA1c, although cardiovascular risk profile was acceptable. Therapeutic and educational efforts must be reinforced mainly in adolescents, emphasizing the importance of adequate nutritional management as a primary method to treat this entity.

ABSTRACT Objective: To verify the prevalence of poor sleep quality and its association with personal characteristics and symptoms of depression, anxiety and stress in amateur adolescent athletes. Methods: 309 adolescent athletes aged between 10 and 19 years were enrolled. Data collection included: a structured questionnaire, with personal information; the Pittsburgh Sleep Quality Index (PSQI); and the Depression, Anxiety and Stress Scale (DASS-21). Results are described in mean and standard deviation (numeric variables) and absolute and relative frequencies (categorical variables). For the inferential analysis, Student’s t-test and chi-square test were performed, in addition to Poisson regression. Prevalence ratios (PR) were calculated in a 95% confidence interval (95%CI). Results: The mean age of participants was 14.1±2.1, being 13.8±2.0 and 15.0±2.1, respectively, for those with good and poor sleep quality. Poor sleep quality was recorded in 28.2% (n=87), depression in 26.9% (n=83) and anxiety/stress in 40.1% (n=124). Poor sleep quality was associated with ages between 15 and 19 years (PR 1.24; 95%CI 1.14-1.37), overweight (PR 1.12; 95%CI 1.01-1.24) and psychological symptoms of depression (PR 1.23; 95%CI 1.08-1.40) and anxiety/stress (PR 1.16; 95%CI 1.04-1.28). Conclusions: The presence of overweight and psychological symptoms and the age over 15 years were risk factors for increasing the likelihood of poor sleep quality in adolescent athletes.

In October 2014, the Advisory Committee on Immunization Practices (ACIP) approved the Recommended Immunization Schedule for Adults Aged 19 Years or Older, United States, 2015. This schedule provides a summary of ACIP recommendations for the use of vaccines routinely recommended for adults aged 19 years or older in two figures, footnotes for each vaccine, and a table that describes primary contraindications and precautions for commonly used vaccines for adults. Changes in the 2015 adult immunization schedule from the 2014 schedule included the August 2014 recommendation for routine administration of the 13-valent pneumococcal conjugate vaccine (PCV13) in series with the 23-valent pneumococcal polysaccharide vaccine (PPSV23) for all adults aged 65 years or older, the August 2014 revision on contraindications and precautions for the live attenuated influenza vaccine (LAIV), and the October 2014 approval by the Food and Drug Administration to expand the approved age for use of recombinant influenza vaccine (RIV). These revisions were also reviewed and approved by the American College of Physicians, American Academy of Family Physicians, American College of Obstetricians and Gynecologists, and American College of Nurse-Midwives.

Despite being associated with multiple disease processes and cardiovascular outcomes, uric acid (UA) reference ranges for adolescents are lacking. We sought to describe the distribution of UA and its relationship to demographic, clinical, socioeconomic, and dietary factors among U.S. adolescents. A nationally representative subsample of 1,912 adolescents aged 13-18 years in NHANES 2005-2008 representing 19,888,299 adolescents was used for this study. Percentiles of the distribution of UA were estimated using quantile regression. Linear regression models examined the association of UA and demographic, socioeconomic, and dietary factors. Mean UA level was 5.14 ± 1.45 mg/dl. Mean UA increased with increasing age and was higher in non-Hispanic white race, male sex, higher body mass index (BMI) Z-score, and with higher systolic blood pressure. In fully adjusted linear regression models, sex, age, race, and BMI were independent determinants of higher UA. This study defines serum UA reference ranges for adolescents. Also, it reveals some intriguing relationships between UA and demographic and clinical characteristics that warrant further studies to examine the pathophysiological role of UA in different disease processes.

We studied the frequency of documentation of disclosure of HIV status in medical charts and its correlates among HIV-infected adolescents in 2009, in Abidjan, Côte d'Ivoire. The PRADO-CI is a cross-sectional study aimed at studying HIV-infected adolescents' social, psychological, and behavioural difficulties and their determinants in Abidjan, Côte d'Ivoire. In this study, we present specific analyses on disclosure. All HIV-infected adolescents aged 13-21 years and followed at least once in 2009 in two urban HIV-care centres in Abidjan (Cepref and Yopougon Teaching Hospital) were enrolled in the study. Standardized data were extracted from medical records to document if there was notification of disclosure of HIV status in the medical record. Frequency of notification of HIV disclosure was estimated with its 95% confidence interval (CI) and correlates were analyzed using logistic regression. In 2009, 229 adolescents were included: 126 (55%) males; 93% on antiretroviral therapy (ART), 61% on cotrimoxazole prophylaxis. Their median age was 15 years at the time of the study. Among the 193 patients for whom information on HIV status disclosure was documented (84%), only 63 (32.6%; 95% CI=26.0-39.3%) were informed of their status. The proportion of adolescents informed increased significantly with age: 19% for 13-15 years, 33% for 16-18 years and 86% for 19-21 years (p <0.0001). Adolescents on ART tended to be more likely to be informed of their HIV status (34.5%) than those not treated (13.3%) (p=0.11). Those on cotrimoxazole were significantly more likely to be informed (39.6%) than those not (21.9%) (p=0.01). Disclosure was significantly higher in adolescents with a history of ART regimen change (p=0.003) and in those followed in the Cepref (48.4%) compared to the Yopougon Teaching Hospital (24.8%), (p=0.001). In multivariate analyses, disclosed HIV status was significantly higher in those followed-up in the Cepref compared to the other centre: adjusted odds ratio

Background Meningococcal serogroup C (MenC) specific antibody levels decline rapidly after a single primary MenC conjugate (MenCC) vaccination in preschool children. A second MenCC vaccination during (pre)adolescence might attain longer lasting individual and herd protection. We aimed to establish an appropriate age for a (pre)adolescent MenCC booster vaccination. Methods A phase-IV trial with healthy 10-year-olds (n = 91), 12-year-olds (n = 91) and 15-year-olds (n = 86) who were primed with a MenCC vaccine nine years earlier. All participants received a booster vaccination with the same vaccine. Serum bactericidal antibody assay titers (SBA, using baby rabbit complement), MenC-polysaccharide (MenC-PS) specific IgG, IgG subclass and avidity and tetanus-specific IgG levels were measured prior to (T0) and 1 month (T1) and 1 year (T2) after the booster. An SBA titer ≥8 was the correlate of protection. Results 258 (96.3%) participants completed all three study visits. At T0, 19% of the 10-year-olds still had an SBA titer ≥8, compared to 34% of the 12-year-olds (P = 0.057) and 45% of the 15-year-olds (P<0.001). All participants developed high SBA titers (GMTs>30,000 in all age groups) and MenC-PS specific IgG levels at T1. IgG levels mainly consisted of IgG1, but the contribution of IgG2 increased with age. At T2, 100% of participants still had an SBA titer ≥8, but the 15-year-olds showed the highest protective antibody levels and the lowest decay. Conclusion Nine years after primary MenCC vaccination adolescents develop high protective antibody levels in response to a booster and are still sufficiently protected one year later. Our results suggest that persistence of individual - and herd - protection increases with the age at which an adolescent booster is administered.

Data on menstrual experiences and their impact on quality of life among women in developing countries are scant. The aim of this study was to assess the prevalence of dysmenorrhoea among adolescent girls in Sidon city and suburbs, Lebanon, and to explore its possible relationship with menstrual experience. In a cross-sectional design, 389 post-menarcheal schoolgirls aged 13-19 years were selected using a cluster random sampling method. Of these 161 (41.4%) were regularly or sometimes absent from school due to menstrual problems and 289 (74.3%) experienced dysmenorrhoea. Nevertheless only 7.3% of the girls had consulted a physician about dysmenorrhoea. Three-quarters of these young women (75.2%) had scores indicating negative menstrual experience based on the Menstrual Experience and Behavior Questionnaire. Significant predictors of dysmenorrhoea were negative menstrual experience, younger age of girl, longer duration of bleeding and longer cycle length. Better reproductive health educational programmes focusing on menstruation are needed for female adolescents.

Sex differences in suicide rates and suicide methods was compared among adolescents in South Korea, Japan, Finland, and the United States. This study analyzed suicide rates and suicide methods of adolescents aged 15-19 years in four countries, using the World Health Organization mortality database. Among both male and female adolescents, the most common method of suicide was jumping from heights in South Korea and hanging in Japan. In Finland, jumping in front of moving objects and firearms were frequently used by males, but not by females. In the United States, males were more likely to use firearms, and females were more likely to use poison. The male to female ratio of suicide rates was higher in the United States (3.8) and Finland (3.6) than in Korea (1.3) and Japan (1.9). Sex differences in suicide methods may contribute to differences in the suicide rates among males and female adolescents in different countries.

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. 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. National secondary schools in Peninsular Malaysia. 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. 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). 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. The study shows a high prevalence of vitamin D deficiency among young adolescents. Main risk factors are gender, ethnicity, place of residence and obesity.

This study aimed to determine for the first time the age- and gender-specific reference intervals for biomarkers of bone, metabolism, nutrition, and obesity in a nationally representative sample of the Iranian children and adolescents. We assessed the data of blood samples obtained from healthy Iranian children and adolescents, aged 7 to 19 years. The reference intervals of glucose, lipid profile, liver enzymes, zinc, copper, chromium, magnesium, and 25-hydroxy vitamin D [25(OH)D] were determined according to the Clinical & Laboratory Standards Institute C28-A3 guidelines. The reference intervals were partitioned using the Harris-Boyd method according to age and gender. The study population consisted of 4800 school students (50% boys, mean age of 13.8 years). Twelve chemistry analyses were partitioned by age and gender, displaying the range of results between the 2.5th to 97.5th percentiles. Significant differences existed only between boys and girls at 18 to 19 years of age for low density lipoprotein-cholesterol. 25(OH)D had the only reference interval that was similar to all age groups and both sexes. This study presented the first national database of reference intervals for a number of biochemical markers in Iranian children and adolescents. It is the first report of its kind from the Middle East and North Africa. The findings underscore the importance of providing reference intervals in different ethnicities and in various regions.
