This study examines gender and age differences in parenting practices among African adolescents in South Africa. The Perceived Parent Behavior Inventory (PPBI) was administered to 274 students (14 through 18 years of age) in Standards 6 through 10 who attended one public coeducational high school in Cape Town. The results indicate that for the three scales of the PPBI, girls score higher than boys, and that on the total score and two of the PPBI scales, the level of perceived parental behaviors decreases with age. These findings support the hypotheses that competence in social interaction is a more significant factor for girls than for boys and that younger adolescents have a closer association with their parents than do their older counterparts. The findings have important implications for the study of adolescent development in an African context.

Objective: To invesigate the epidemic status of the metabolic syndrome (MS) among mainland Chinese adolescents aged 10-17 in 2010-2012. Methods: Data were collected from Chinese Nutrition and Health Surveillance in 2010-2012. Multi-stage stratified proportion to the population cluster random sampling method was conducted to determine 16 872 adolescents in 150 counties from 31 provinces in mainland China. The epidemic status of metabolic syndrome was analyzed by China criterion (defined by Chinese Pediatric Society, Chinese Medical Association) and Cook criterion, respectively. The prevalence of MS and 95 %CI were calculated through weighted complex sampling processing by population data released by the National Bureau of Statistics in 2009. Results: Based on China criterion, the weighted prevalence of MS was 2.4% (95 % CI: 2.1%-2.6%) among Chinese adolescents aged 10-17. Prevalence in urban was higher than in rural (2.8%, 95 %CI: 2.4%-3.2% and 1.9%, 95 %CI: 1.6%-2.3%, respectively). Prevalence in boys and girls were 2.7% (95 % CI: 2.3%-3.0%), and 2.0% (95 % CI: 1.7%-2.4%), respectively. Based on Cook criterion, the weighted prevalence was 4.3% (95 % CI: 4.0%-4.7%) . The highest weighted prevalence of the components of the metabolic syndrome was low high-density lipoprotein cholesterol (26.8%, 95 % CI: 26.0%-27.5%), followed by high fasting glucose (11.5%, 95 % CI: 11.0%-12.0%), abdominal obesity (11.1%, 95 %CI: 10.6%-11.7%) , hypertriglyceridemia (8.8%, 95 %CI: 8.4%-9.3%) , and high blood pressure (6.4%, 95 % CI: 6.0%-6.8%). Conclusion: Among the five indicators of metabolic syndrome, the prevalence of central obesity and hypertriglyceridemia were relative high in Chinese adolescents aged 10-17 years, though the prevalence of metabolic syndrome was not high.

Previous research suggests that cognitive functioning is associated with the risk of several adult psychiatric disorders. In this study we investigated whether adolescents who perform worse than expected at secondary school are at a higher risk for general mental health problems. In a cross-sectional survey comprising 10,866 Dutch adolescents aged 13 to 16 years, underachievement at secondary school was defined as the discrepancy between predicted school grade and actual grade 1 or 3 years later. Mental health problems were assessed using the Strengths and Difficulties Questionnaire. We investigated the association of underachievement with mental health problems using logistic regression, adjusting for potential confounders. Underachievement was associated with general psychopathology in pupils aged 13 to 14 years (odds ratio [OR], 1.86; 95% confidence interval [CI], 1.47-2.37) and in pupils aged 15 to 16 years (OR, 2.05; 95% CI, 1.67-2.52) in a multivariate analysis including sociodemographic factors. The association between underachievement and mental health problems was attenuated when school factors such as teacher advice and interaction between underachievement and teacher advice were added, but underachievement remained significantly associated with mental health problems in adolescents in the higher educational tracks (pupils aged 13-14 years: OR, 2.22; 95% CI, 1.07-4.60 and OR, 2.41; 95% CI, 1.10-5.30, age 15-16 years: OR, 2.63; 95% CI, 1.38-5.03). In the multivariate analysis including the interaction between underachievement and teacher advice, a significant interaction effect occurs between underachievement and teacher advice in the higher tracks. Values of OR and CI are given for each significant interaction term. In the younger age group (pupils aged 13-14 years) this results in 2 sets of OR and CI. This association was most pronounced for the hyperactivity subscale of the Strengths and Difficulties Questionnaire. Underachievement at secondary school

To assess the prevalence of the metabolic syndrome (MetS) in overweight/obese children and adolescents of an out-patient clinic, and to compare two definitions of MetS in adolescents. In total, 528 overweight / obese children (3-16 years), of multi-ethnic origin, underwent an oral glucose tolerance test, blood collections and anthropometric measurements. In children <10 years, MetS was assessed according to child-specific cut-off values (MetS-child). In adolescents, MetS-child and MetS-adolescent (the recommendation of the International Diabetes Federation for adolescents) were compared. The prevalence of MetS-child within the cohort (median age 11.3, range 3.1-16.4 yrs) was 18.6% (children <10 years vs. adolescents: 14.1% vs. 20.7%, P=0.073). Insulin resistance was present in 47.7% (children <10 years vs. adolescents: 21.8% vs. 60.1%, P<0.001). MetS-child was highly prevalent, and not statistically significant between age groups. In adolescents, the prevalence of MetS-adolescent was higher than MetS-child (33.2% vs. 20.7%, P<0.001). The agreement between the MetS definitions was moderate (kappa =0.51), with the agreement for the MetS-criteria for abnormal lipid levels being substantial to very good (kappa =0.71 to 0.80). MetS-child was highly prevalent in overweight/obese children and adolescents. A higher prevalence of MetS according to adolescent- as compared to child-specific criteria was found.

Physical activity levels in Portuguese adolescents: A 10-year trend analysis (2006-2016).

Previous studies have indicated that only a small proportion of Portuguese adolescents attain sufficient levels of physical activity for health. However, it is unknown whether the levels of moderate to vigorous physical activity (MVPA) have changed over a considerable time period in this country. Therefore, the aims of the present study were to examine the 10-year trend changes in self-reported MVPA among adolescents and also investigate differences by sex and age. This study compared two cross-sectional cohorts of youngsters aged 12-18 years, recruited in 2006 (N=1010; 461 boys and 549 girls) and in 2016 (N=1096; 461 boys and 635 girls), using identical procedures and instruments. The outcome variable, MVPA, was assessed by using the PACE+ screening measure. Main results showed a considerable decline in the overall levels of physical activity between 2006 and 2016 (-10.8%), as well as a small and declining proportion of adolescents achieving the international physical activity recommendations (2006: 10.7%; 2016: 8.1%). Age and sex-specific comparisons by time periods indicated that the 13- and 14-year-old male adolescents reported lower levels of MVPA in 2016 than their counterparts in 2006, and that the MVPA decline between the subgroups of 12- and 18-year-olds was higher in girls, in both 2006 and 2016. This study provides evidence of a secular decrease in self-reported MVPA levels among Portuguese adolescents. These results reinforce the need for interventions and policies aimed at promoting a more active lifestyle throughout adolescence. Copyright © 2017 Sports Medicine Australia.

The purposes of this study were to examine age and gender differences in throwing performance across an underexplored portion of the lifespan: middle adolescents (14-17 years old), young adults (18-25 years old), and adults (35-55 years old). Throwing performance was assessed using the body component levels from Roberton's developmental sequences for force and ball velocity that were recorded by a radar gun. Participants in each age group performed between 5 to 10 forceful overhand throws toward a target approximately 15m to 20m from the thrower. A Wilcoxon-Mann-Whitney Test was used to determine gender differences and a Wilcoxon-Signed Ranks Test was used to determine age-group differences for each component. Gender and age-group differences in ball speed were determined by a 3 (age group) x 2 (gender) factorial analysis of variance with follow-up post-hoc tests. Young-adult men had higher body component levels and ball speed compared with the adolescent boys and adult men. Female age-group differences existed only for humerus action between young-adult and adult groups and for ball speed between young-adult and adolescent groups. Gender differences (p < .01) existed in component levels for the adolescent and young-adult groups, but not the adult groups. Gender differences in ball speed (p < .001) existed within each age group. Although these data were cross-sectional, the regressive developmental changes observed and the narrowing gender gap may eventually provide insight related to the relationships among motor skill competence, physical fitness, and physical activity across the lifespan.

"First, do no harm": legal guidelines for health programmes affecting adolescents aged 10-17 who sell sex or inject drugs.

PubMed

Conner, Brendan

2015-01-01

There is a strong evidence base that the stigma, discrimination and criminalization affecting adolescent key populations (KPs) aged 10-17 is intensified due to domestic and international legal constructs that rely on law-enforcement-based interventions dependent upon arrest, pre-trial detention, incarceration and compulsory "rehabilitation" in institutional placement. While there exists evidence and rights-based technical guidelines for interventions among older cohorts, these guidelines have not yet been embraced by international public health actors for fear that international law applies different standards to adolescents aged 10-17 who engage in behaviours such as selling sex or injecting drugs. As a matter of international human rights, health, juvenile justice and child protection law, interventions among adolescent KPs aged 10-17 must not involve arrest, prosecution or detention of any kind. It is imperative that interventions not rely on law enforcement, but instead low-threshold, voluntary services, shelter and support, utilizing peer-based outreach as much as possible. These services must be mobile and accessible, and permit alternatives to parental consent for the provision of life-saving support, including HIV testing, treatment and care, needle and syringe programmes, opioid substitution therapy, safe abortions, antiretroviral therapy and gender-affirming care and hormone treatment for transgender adolescents. To ensure enrolment in services, international guidance indicates that informed consent and confidentiality must be ensured, including by waiver of parental consent requirements. To remove the disincentive to health practitioners and researchers to engaging with adolescent KPs aged 10-17 government agencies and ethical review boards are advised to exempt or grant waivers for mandatory reporting. In the event that, in violation of international law and guidance, authorities seek to involuntarily place adolescent KPs in institutions, they are

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.

There is limited evidence on how diet changes over the transition from primary to secondary school. In this study we investigated changes in diet from age 10 (2007) to age 14 years (2011) and the contribution of school-time consumption and school lunch choice to such changes. The 351 participants with dietary data (4 day food record) available at baseline (age 10 years) and follow-up (age 14 years) were included. Multi-level regression models were fitted for absolute or change in food and nutrient intake, cross-classified by primary and secondary school attended as appropriate, with adjustment for covariates and mis-reporting. From age 10 to age 14 years, children decreased energy intake from sugars (-2.6% energy (%E)) (standard error (SE) 0.44) and from saturated fats (-0.54%E (SE 0.18)), decreased fruit (-3.13 g/MJ (SE 1.04)) and vegetables (-1.55 g/MJ (SE 0.46)) consumption and increased sugar sweetened beverage (SSB) (4.66  g/MJ (SE 1.87)) and fries (1.31  g/MJ (SE 0.39)) consumption. Intake of snack foods, SSBs, and fries, but also fruits and vegetables was higher outside school hours. Prospective change from non-school lunch to school lunch, compared to maintaining non-school lunch consumption, was associated with decreased consumption of savoury snacks (-8.32 g/day (SE 2.03)), increased consumption of fries (12.8 g/day (SE 4.01)) and decreased consumption of fruit (-25.16 g/day (SE 11.02)) during school hours. Changes in diet from age 10 to age 14 years differed within and outside of school hours. Consumption of a school lunch, compared to lunch obtained elsewhere, was associated with negative as well as positive changes in diet, suggesting that any efforts to encourage school lunch take-up need to be accompanied by further efforts to improve school lunch provision to meet nutritional guidelines.

Eating habits of 104 male participants (ages 10 to 14 years) in organized ice hockey were compared across age groups and levels of competition. The boys were members of either a highly skilled and intensively active competitive league group (CL) or a less skilled, moderately active house league group (HL). Eating habits were recorded during a school day from a 24 hour recall questionnaire administered by a trained interviewer. The types and amounts of foods eaten were recorded and caloric intake was calculated. The total caloric intakes were not significantly different by age or competitive group. The boys had higher caloric intakes by age (200 kcal day-1) than reported by other studies but the caloric intake by kilogram of body weight was similar. There was a trend towards larger caloric intake by the CL boys (ages 10 and 11 years), however when divided by body weight the differences were not significant suggesting that this trend was due to a greater body weight of the CL boys and not a significantly increased caloric expenditure. The types of foods eaten (fruit, vegetables, dairy, meat, bread or "empty calories") were similar for the two activity groups and across ages 10 to 14 years. The caloric intakes of dairy and meat products of both groups were significantly higher than for the other food groups.

Data on adolescents' sexual and condom use behaviors provides an empirical basis for a range of social, educational, clinical, and public health endeavors. This study has two purposes: to describe the recent and lifetime prevalence of a variety of sexual behaviors; and, to describe factors associated with condom use at last penile-vaginal intercourse. Data included those from male (N = 414) and female (N = 406) adolescents (ages 14-17 years) from a nationally representative probability sample. Survey items addressed occurrence (past 90 days, past year, lifetime) of solo masturbation, partnered masturbation, oral sex given to a partner, oral sex received from a partner, vaginal intercourse, and anal intercourse. Participants reporting partnered sexual behaviors in the past year completed additional items about condom use, location of sex, partner characteristics, other sexual behaviors, and alcohol or marijuana use at the most recent sexual event. Adjusted rates (by gender) of sexual behaviors, and characteristics of most recent vaginal sex event as a function of condom use/non-use. Lifetime prevalence of solo masturbation was common for males (80%) and females (48%). Lifetime prevalence of penile-vaginal sex increased with each year of age for both adolescent men and women; however, penile-vaginal sex within the previous 90 days was much less frequently reported. Rates of condom use for penile-vaginal sex were 80% for males and 69% for females. Lifetime anal sex rates were 4.7% for males and 5.5% for females. Sexual behavior among adolescents was more prevalent and diverse in older adolescent cohorts. Condom use for penile-vaginal intercourse was reported for a majority of events. © 2010 International Society for Sexual Medicine.

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

Limited research is focused on suicides in children aged below 15 years. To analyse worldwide suicide rates in children aged 10-14 years in two decades: 1990-1999 and 2000-2009. Suicide data for 81 countries or territories were retrieved from the World Health Organization Mortality Database, and population data from the World Bank data-set. In the past two decades the suicide rate per 100 000 in boys aged 10-14 years in 81 countries has shown a minor decline (from 1.61 to 1.52) whereas in girls it has shown a slight increase (from 0.85 to 0.94). Although the average rate has not changed significantly, rates have decreased in Europe and increased in South America. The suicide rates remain critical for boys in some former USSR republics. The changes may be related to economic recession and its impact on children from diverse cultural backgrounds, but may also be due to improvements in mortality registration in South America.

We examined the development of self-esteem in adolescence and young adulthood. Data came from the Young Adults section of the National Longitudinal Survey of Youth, which includes 8 assessments across a 14-year period of a national probability sample of 7,100 individuals age 14 to 30 years. Latent growth curve analyses indicated that self-esteem increases during adolescence and continues to increase more slowly in young adulthood. Women and men did not differ in their self-esteem trajectories. In adolescence, Hispanics had lower self-esteem than Blacks and Whites, but the self-esteem of Hispanics subsequently increased more strongly, so that at age 30 Blacks and Hispanics had higher self-esteem than Whites. At each age, emotionally stable, extraverted, and conscientious individuals experienced higher self-esteem than emotionally unstable, introverted, and less conscientious individuals. Moreover, at each age, high sense of mastery, low risk taking, and better health predicted higher self-esteem. Finally, the results suggest that normative increase in sense of mastery accounts for a large proportion of the normative increase in self-esteem.

Although childhood shyness has been linked to social anxiety problems, the factors playing a role in this association have gone largely unexplored. Here we examined the potential moderating roles of sex and age on this relation in a sample of 119 (75 girls) children (10-12 years) and adolescents (14-16 years). As predicted, shyness was positively associated with social anxiety symptoms. Sex, but not age, served as a moderating factor in linking shyness and social anxiety. Specifically, shyness was more strongly associated with social anxiety symptoms among girls than boys. These results suggest the importance of considering sex differences when examining the relation between shyness and social anxiety in childhood and adolescence.

Suicide in elementary school-aged children is not well studied, despite a recent increase in the suicide rate among US black children. The objectives of this study were to describe characteristics and precipitating circumstances of suicide in elementary school-aged children relative to early adolescent decedents and identify potential within-group racial differences. We analyzed National Violent Death Reporting System (NVDRS) surveillance data capturing suicide deaths from 2003 to 2012 for 17 US states. Participants included all suicide decedents aged 5 to 14 years (N = 693). Age group comparisons (5-11 years and 12-14 years) were conducted by using the χ 2 test or Fisher's exact test, as appropriate. Compared with early adolescents who died by suicide, children who died by suicide were more commonly male, black, died by hanging/strangulation/suffocation, and died at home. Children who died by suicide more often experienced relationship problems with family members/friends (60.3% vs 46.0%; P = .02) and less often experienced boyfriend/girlfriend problems (0% vs 16.0%; P < .001) or left a suicide note (7.7% vs 30.2%; P < .001). Among suicide decedents with known mental health problems (n = 210), childhood decedents more often experienced attention-deficit disorder with or without hyperactivity (59.3% vs 29.0%; P = .002) and less often experienced depression/dysthymia (33.3% vs 65.6%; P = .001) compared with early adolescent decedents. These findings raise questions about impulsive responding to psychosocial adversity in younger suicide decedents, and they suggest a need for both common and developmentally-specific suicide prevention strategies during the elementary school-aged and early adolescent years. Further research should investigate factors associated with the recent increase in suicide rates among black children. Copyright © 2016 by the American Academy of Pediatrics.

Fractures which need urgent or emergency treatment are common in children and adolescents. This study investigated the incidence patterns of pediatric and adolescent orthopaedic fractures according to age groups and seasons in South Korea based on population data. Data on the number of pediatric and adolescent patients under the age of 18 years who utilized medical services due to fractures were retrieved from the Health Insurance Review and Assessment service in South Korea. The data included four upper extremity and two lower extremity fractures according to four age groups (0-4 years, 5-9 years, 10-14 years, and 15-18 years). Incidences of the fractures were calculated as the incidence per 10,000 per year, and patterns according to age groups and seasons were demonstrated. The annual incidence of clavicle, distal humerus, both forearm bone, distal radius, femoral shaft and tibial shaft fractures were 27.5, 34.6, 7.7, 80.1, 2.5, and 9.6 per 10,000 per year in children and adolescents, respectively. Clavicle and distal radius fractures showed significant seasonal variation for all age groups but femoral shaft fracture showed no significant seasonal variation for any of the age groups. The four upper extremity fractures tended to show greater variations than the two lower extremity fractures in the nationwide database in South Korea. The study results are believed to be helpful in the planning and assignment of medical resources for fracture management in children and adolescents.

Liver enzymes alanine aminotransferase (ALT) and gamma glutamyl transferase (GGT) are markers for type 2 diabetes mellitus (T2DM); alkaline phosphatase is a marker of liver disease. Mexican-American adolescents are disproportionately affected by T2DM, while in Mexico its prevalence is emerging. We assessed liver biomarkers and lipid profiles among Mexican and Mexican-American adolescents 10–14 years old with high/low risk of T2DM through a cross-sectional, descriptive study (Texas n = 144; Mexico n = 149). We included family medical histories, anthropometry, and blood pressure. Obesity was present in one-third of subjects in both sites. ALT (UL) was higher (p < 0.001) in high-risk adolescents (23.5 ± 19.5 versus 17.2 ± 13.4 for males, 19.7 ± 11.6 versus 15.1 ± 5.5 for females), in Toluca and in Texas (26.0 ± 14.7 versus 20.0 ± 13.2 for males, 18.2 ± 13.4 versus 14.6 ± 10.1 for females), as well as GGT (UL) (p < 0.001) (18.7 ± 11.1 versus 12.4 ± 2.3 for males, 13.6 ± 5.8 versus 11.5 ± 3.9 for Mexican females; 21.0 ± 6.8 versus 15.4 ± 5.5 for males, 14.3 ± 5.0 versus 13.8 ± 5.3 for females in Texas). We found no differences by sex or BMI. Total cholesterol and HDL were higher among Mexican-Americans (p < 0.001). In conclusion, multiple risk factors were present in the sample. We found differences by gender and between high and low risk for T2DM adolescents in all liver enzymes in both sites. PMID:28929119

To examine whether age of onset, duration, or type of medication therapy for attention-deficit/hyperactivity disorder (ADHD) is associated with substance use during adolescence. Nationally representative samples of high school seniors were surveyed via self-administered questionnaires. The sample consisted of 40,358 individuals from 10 independent cohorts (2005-2014) and represented a population that was 52% female, 62% white, 10% African American, 14% Hispanic, and 14% other race/ethnicity. Design-based logistic regression analyses were used to test the associations between age of onset, duration, and type of ADHD medication therapy and recent substance use, controlling for potential confounding factors. Individuals who initiated stimulant medication therapy for ADHD later (aged 10-14 years and 15 years and older) and for shorter duration (2 years or less and 3-5 years) as well as those who reported only nonstimulant medication therapy for ADHD had significantly greater odds of substance use in adolescence relative to individuals who initiated stimulant medication therapy for ADHD earlier (aged 9 years or less) and for longer duration (6 or more years). The odds of substance use generally did not differ between population controls (youth without ADHD and unmedicated youth with ADHD) and individuals who initiated stimulant medication for ADHD early (aged 9 years or less) and for longer duration (aged 6 or more years). Relative to later onset and shorter duration of stimulant treatment for ADHD, early onset and longer duration of stimulant treatment for ADHD was associated with a risk of substance use during adolescence that is lower than and similar to that in the general population.

2017-05-01

Daytime sleepiness increases across adolescence. This increase is commonly attributed to insufficient sleep durations resulting from increasingly limited time in bed. We tested the effects of 3 sleep schedules on daytime sleepiness and whether these effects changed with age in early adolescence. In 77 children ranging in age from 9.9 to 14 years, objective (multiple sleep latency test [MSLT]) and subjective (Karolinska sleepiness scale [KSS]) sleepiness was measured following 4 consecutive nights of either 7, 8.5, or 10 hours in bed. All participants completed all 3 sleep schedules. The order in which they completed the schedules was not randomized but was accounted for in all statistical analyses. Time in bed restriction decreased sleep duration and increased objective and subjective daytime sleepiness. Although the sleep durations did not change with age, the likelihood of falling asleep during the MSLT increased with age. Nevertheless, sleep restriction produced a greater increase in MSLT-measured sleepiness in younger participants. Subjective sleepiness measured with the KSS increased with shorter sleep duration, but this effect did not change with age. Increasing objective daytime sleepiness in early adolescence cannot simply be attributed to reduced sleep due to restricted sleep schedules. We propose that some of the increased daytime sleepiness of adolescents is a consequence of adolescent brain reorganization driven by synaptic pruning which decreases the intensity of waking brain activity. © Sleep Research Society 2017.

In 2011, Chile experienced an increase in the number of cases of IMD caused by Neisseria meningitidis group W. This epidemiological scenario prompted authorities to implement prevention strategies. As part of these strategies, the Institute of Public Heath of Chile conducted a cross-sectional study to determine the prevalence of pharyngeal carriage of N. meningitidis in a representative sample of healthy children and adolescents aged 10-19 years. The identification of presumptive N. meningitidis strains was performed by testing carbohydrate utilization in the National Reference Laboratory at the ISP. Association of meningococcal carriage with risk factors was analyzed by calculating the Odds Ratio. Selected variables were included in a logistic model for risk analyses. The prevalence of carriage of N. meningitidis was 6.5% (CI: 5.7-7.3%). Older age (carriers: 14.2±0.29 vs. non-carriers: 13.8±0.08 years old; p=0.009), cohabitation with children (carriers: 0.9±0.13 vs. non-carriers: 0.7±0.03; p=0.028), number of smoking cohabitants (carriers: 0.55±0.13 vs. non-carriers: 0.44±0.03) and frequent attendance to crowded social venues (carriers: 49% vs. non-carriers: 37%; p=0.008) were determined to favor carriage. Statistical modeling showed that meningococcal carriage was associated with older age (OR: 1.077, p-value: 0.002) and cohabitation with children (OR: 1.182, p-value: 0.02).

Research indicates that childhood maltreatment is strongly associated with high levels of adolescent depression and anxiety symptoms. Using LONGSCAN data and taking into account the range of family characteristics related to adversity (poverty, primary caregiver substance abuse) and protective factors (living with biological mother and father), the present study assessed the complex resilience process in which child intelligence (age 6) mediated the relationship between early childhood maltreatment (age 0-4) and adolescent symptoms of depression and anxiety (age 14). We also assessed if mid (age 6-8) and late (age 10-12) childhood maltreatment moderated this mediation. We found that mid-childhood intelligence mediated the negative effect of early childhood maltreatment (age 0-4) on anxiety symptoms (age 14), but not on depressive symptoms (age 14). We also found the effect of timing of maltreatment: early childhood maltreatment (age 0-4) predicted more anxiety symptoms in adolescence, whereas late childhood/early adolescent (age 10-12) maltreatment predicted more symptoms of depression in adolescence. In addition, mid (age 6-8) and late (age 10-12) childhood maltreatment dampened the protective effect of IQ (age 6) against anxiety (age 14). In sum, current evidence shows that low anxiety and depression symptoms in adolescence following childhood maltreatment was achieved through different pathways, and that early and late childhood/early adolescence were more sensitive periods for development of psychopathology related to depression and anxiety in adolescence.

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.

2007-10-01

The first longitudinal investigation of the extent to which same-age and older schoolmates' smoking and non-smoking are associated with adolescents' smoking transitions during three grade intervals. Same-age and older schoolmates' smoking and non-smoking were assessed when adolescents were at grades 5 (age 10), 7 (age 12) and 9 (age 14). Adolescents' smoking transitions were assessed at three grade intervals: 5th-7th (age 10-12), 7th-9th (age 12-14) and 9th-12th (age 14-17). Forty Washington State school districts. Smoking questionnaire data were gathered on a cohort of adolescents (n = 4354 for same-age schoolmate analysis; n = 1833 for older schoolmate analysis) that was 49% female and 91% Caucasian. No significant evidence that same-age schoolmates' smoking or non-smoking was associated with any of the adolescent smoking transitions at any of the three grade intervals. In contrast, the probability that each older schoolmate's smoking was associated with the adolescent making the transition to trying smoking was 1% (95% CI: 0.4%, 1.5%) and with the transition from trying to monthly smoking was also 1% (95% CI: 0.2%, 2.0%) during the 7th-9th grade (age 12-14) interval. Moreover, each older schoolmate's non-smoking was associated with a 1.001-1.006 (all P < 0.05) relative risk of an adolescent not trying smoking or escalating from trying to monthly smoking at several grade intervals. Interventions should perhaps focus on the influence of both smoking and non-smoking older schoolmates during late childhood and early adolescence.

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.

Tennis requires repetitive overhead movements that can lead to upper extremity injury. The scapula and the shoulder play a vital role in injury-free playing. Scapular dysfunction and glenohumeral changes in strength and range of motion (ROM) have been associated with shoulder injury in the overhead athlete. To compare scapular position and strength and shoulder ROM and strength between Swedish elite tennis players of 3 age categories (<14, 14-16, and >16 years). Cross-sectional study. Tennis training sports facilities. Fifty-nine adolescent Swedish elite tennis players (ages 10-20 years) selected based on their national ranking. We used a clinical screening protocol with a digital inclinometer and a handheld dynamometer to measure scapular upward rotation at several angles of arm elevation, isometric scapular muscle strength, glenohumeral ROM, and isometric rotator cuff strength. Players older than 16 years showed less scapular upward rotation on the dominant side at 90° and 180° (P < .05). Although all absolute scapular muscle strength values increased with age, there was no change in the body-weight-normalized strength of the middle (P = .9) and lower (P = .81) trapezius or serratus anterior (P = .17). Glenohumeral internal-rotation ROM and total ROM tended to decrease, but this finding was not statistically significant (P = .052 and P = .06, respectively). Whereas normalized internal-rotator strength increased from 14 to 16 years to older than 16 years (P = .009), normalized external-rotator and supraspinatus strength remained unchanged. Age-related changes in shoulder and scapular strength and ROM were apparent in elite adolescent tennis players. Future authors should examine the association of these adaptations with performance data and injury incidence.

An investigational quadrivalent Neisseria meningitidis serogroups A, C, W-135, and Y tetanus toxoid conjugate vaccine (MenACWY-TT) has been developed to expand available options for vaccination against invasive meningococcal disease. A total of 784 healthy adolescents and young adults 11 to 25 years of age were randomized (3:1) to receive a single dose of the MenACWY-TT vaccine or a licensed MenACWY diphtheria toxoid conjugate vaccine (MenACWY-DT). An additional nonrandomized group of 88 subjects 10 years of age received the MenACWY-TT vaccine only (MenACWY-TT/10). Immunogenicity was assessed 1 month postvaccination by human complement serum bactericidal assay (hSBA) for all serogroups. Solicited local and general symptoms were recorded for 8 days postvaccination and safety outcomes for 6 months. One month postvaccination, 81.9% to 96.1% of subjects had hSBA titers ≥ 1:8 in the MenACWY-TT group compared with 70.7% to 98.8% in the MenACWY-DT group. Exploratory analyses showed the proportion of subjects with hSBA titers ≥ 1:4 and ≥ 1:8 to be higher in the MenACWY-TT group than in the MenACWY-DT group for serogroups A, W-135, and Y. GMTs adjusted for age strata and baseline titer 1 month postvaccination were higher in the MenACWY-TT group than in the MenACWY-DT group for all 4 serogroups. The percentage of subjects reporting solicited local and general symptoms of any or Grade 3 severity or serious adverse events was similar between the 2 groups. Immune response and reactogenicity in the MenACWY-TT/10 group was similar to that in the MenACWY-TT group, except for higher hSBA-MenA GMTs in the MenACWY-TT/10 group. The investigational MenACWY-TT vaccine was immunogenic in adolescents and young adults, with an acceptable safety profile.

Age differences in resistance to peer influence.

Prior research describes the development of susceptibility to peer pressure in adolescence as following an inverted U-shaped curve, increasing during early adolescence, peaking around age 14, and declining thereafter. This pattern, however, is derived mainly from studies that specifically examined peer pressure to engage in antisocial behavior. In the present study, age differences and developmental change in resistance to peer influence were assessed using a new self-report instrument that separates susceptibility to peer pressure from willingness to engage in antisocial activity. Data from four ethnically and socioeconomically diverse samples comprising more than 3,600 males and females between the ages of 10 and 30 were pooled from one longitudinal and two cross-sectional studies. Results show that across all demographic groups, resistance to peer influences increases linearly between ages 14 and 18. In contrast, there is little evidence for growth in this capacity between ages 10 and 14 or between 18 and 30. Middle adolescence is an especially significant period for the development of the capacity to stand up for what one believes and resist the pressures of one's peers to do otherwise. (c) 2007 APA.

We investigated the criterion-related validity and the reliability of the 1/4 mile run-walk test (MRWT) in children and adolescents. A total of 86 children (n=42 girls) completed a maximal graded treadmill test using a gas analyzer and the 1/4MRW test. We investigated the test-retest reliability of the 1/4MRWT in a different group of children and adolescents (n=995, n=418 girls). The 1/4MRWT time, sex, and BMI significantly contributed to predict measured VO2peak (R2= 0.32). There was no systematic bias in the cross-validation group (P>0.1). The root mean sum of squared errors (RMSE) and the percentage error were 6.9 ml/kg/min and 17.7%, respectively, and the accurate prediction (i.e. the percentage of estimations within ±4.5 ml/kg/min of VO2peak) was 48.8%. The reliability analysis showed that the mean inter-trial difference ranged from 0.6 seconds in children aged 6-11 years to 1.3 seconds in adolescents aged 12-17 years (all P.

The present study examines the secular trends in prevalence of overweight and obesity among urban Asian Indian adolescents in New Delhi (North India). The data were derived from cross-sectional sampling of children, 3493 in year 2006 and 4908 in year 2009, aged 14–17 years studying in privately-funded and government-funded schools. Age, gender and Asian Indian-specific cut offs of body mass index (BMI) were used to define overweight and obesity. The prevalence of obesity increased significantly from 9.8% in 2006 to 11.7% in 2009 (p<0.01), whereas underweight decreased from 11.3% to 3.9% (p<0.001). There was a significantly higher risk of being overweight (OR 1.28; 95% CI, 1.15–1.42) and obese (OR 1.44; 95% CI, 1.24–1.66) in year 2009 than 2006, after adjusting for age, gender and type of school. Males and privately-funded school children had significantly higher increase in prevalence and risk of being overweight and obese over the three years. In conclusion, this study showed an increasing trend in prevalence of overweight and obesity in urban Asian Indian adolescents. More specifically, the study showed the association of this increasing trend of overweight and obesity prevalence with male gender and high socio-economic status, calling for an urgent need for immediate and targeted preventive measures.

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.

Age-Related, Sport-Specific Adaptions of the Shoulder Girdle in Elite Adolescent Tennis Players

Cools, Ann M.; Palmans, Tanneke; Johansson, Fredrik R.

2014-01-01

Context: Tennis requires repetitive overhead movements that can lead to upper extremity injury. The scapula and the shoulder play a vital role in injury-free playing. Scapular dysfunction and glenohumeral changes in strength and range of motion (ROM) have been associated with shoulder injury in the overhead athlete. Objective: To compare scapular position and strength and shoulder ROM and strength between Swedish elite tennis players of 3 age categories (<14, 14–16, and >16 years). Design: Cross-sectional study. Setting: Tennis training sports facilities. Patients or Other Participants: Fifty-nine adolescent Swedish elite tennis players (ages 10–20 years) selected based on their national ranking. Main Outcome Measure(s): We used a clinical screening protocol with a digital inclinometer and a handheld dynamometer to measure scapular upward rotation at several angles of arm elevation, isometric scapular muscle strength, glenohumeral ROM, and isometric rotator cuff strength. Results: Players older than 16 years showed less scapular upward rotation on the dominant side at 90° and 180° (P < .05). Although all absolute scapular muscle strength values increased with age, there was no change in the body-weight–normalized strength of the middle (P = .9) and lower (P = .81) trapezius or serratus anterior (P = .17). Glenohumeral internal-rotation ROM and total ROM tended to decrease, but this finding was not statistically significant (P = .052 and P = .06, respectively). Whereas normalized internal-rotator strength increased from 14 to 16 years to older than 16 years (P = .009), normalized external-rotator and supraspinatus strength remained unchanged. Conclusions: Age-related changes in shoulder and scapular strength and ROM were apparent in elite adolescent tennis players. Future authors should examine the association of these adaptations with performance data and injury incidence. PMID:25098662

To evaluate the role of extracurricular physical activity and sedentary behavior at preschool and primary school age on working memory at primary school age and adolescence, respectively. This prospective study was based on a birth cohort across 4 Spanish regions. In the 3 younger subcohorts (n = 1093), parents reported lifestyle habits of child at age 4 years of age on a questionnaire, and children performed a computerized working memory task at 7 years of age. In the older subcohort (n = 307), the questionnaire was completed at 6 years of age and working memory was tested at 14 years of age. Adjusted regression models were developed to investigate the associations between lifestyle habits and working memory. Low extracurricular physical activity levels at 4 years of age were associated with a nonsignificant 0.95% (95% CI -2.81 to 0.92) reduction of correct responses in the working memory task at age 7 years of age. Low extracurricular physical activity levels at 6 years of age were associated with a 4.22% (95% CI -8.05 to -0.39) reduction of correct responses at age 14 years. Television watching was not associated with working memory. Other sedentary behaviors at 6 year of age were associated with a 5.07% (95% CI -9.68 to -0.46) reduction of correct responses in boys at 14 years of age. Low extracurricular physical activity levels at preschool and primary school ages were associated with poorer working memory performance at primary school age and adolescence, respectively. High sedentary behavior levels at primary school age were related negatively to working memory in adolescent boys. Copyright © 2017 Elsevier Inc. All rights reserved.

Objective To examine whether age of onset, duration, or type of medication therapy for attention-deficit/hyperactivity disorder (ADHD) is associated with substance use during adolescence. Method Nationally representative samples of high school seniors were surveyed via self-administered questionnaires. The sample consisted of 40,358 individuals from ten independent cohorts (2005-2014) and represented a population that was 52% female, 62% White, 10% African-American, 14% Hispanic, and 14% other. Design-based logistic regression analyses were used to test the associations between age of onset, duration, and type of ADHD medication therapy and recent substance use, controlling for potential confounding factors. Results Individuals who initiated stimulant medication therapy for ADHD later (ages 10-14 and 15 years and older) and for shorter duration (2 years or less and 3-5 years) as well as those who reported only non-stimulant medication therapy for ADHD had significantly greater odds of substance use in adolescence relative to individuals who initiated stimulant medication therapy for ADHD earlier (aged 9 or less) and for longer duration (6 or more years). The odds of substance use generally did not differ between population controls (youth without ADHD and unmedicated youth with ADHD) and individuals who initiated stimulant medication for ADHD early (aged 9 or less) and for longer duration (6 or more years). Conclusion Relative to later onset and shorter duration of stimulant treatment for ADHD, early onset and longer duration of stimulant treatment for ADHD was associated with a risk of substance use during adolescence that is lower and similar to that in the general population.

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.

Children's and adolescents' cognitive abilities, social adaptation, and externalizing behaviors are broadly associated with each other at the bivariate level; however, the direction, ordering, and uniqueness of these associations have yet to be identified. Developmental cascade models are particularly well-suited to (1) discern unique pathways among psychological domains and (2) model stability in and covariation among constructs, allowing for conservative tests of longitudinal associations. The current study aimed to identify specific cascade effects among children's cognitive abilities, social adaptation, and externalizing behaviors, beginning in preschool and extending through adolescence. Children (46.2 % female) and mothers (N = 351 families) provided data when children were 4, 10, and 14 years old. Cascade effects highlighted significant stability in these domains. Unique longitudinal associations were identified between (1) age-10 cognitive abilities and age-14 social adaptation, (2) age-4 social adaptation and age-10 externalizing behavior, and (3) age-10 externalizing behavior and age-14 social adaptation. These findings suggest that children's social adaptation in preschool and externalizing behavior in middle childhood may be ideal intervention targets to enhance adolescent well-being.

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

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.

The concept of mental toughness (MT) has gained increasing importance among groups other than elite athletes by virtue of its psychological importance and explanatory power for a broad range of health-related behaviors. However, no study has focused so far on the psychological origins of MT. Therefore, the aims of the present study were: to explore, to what extent the psychological profiles of preschoolers aged five were associated with both (1) MT scores and (2) sleep disturbances at age 14, and 3) to explore possible gender differences. Nine years after their first assessment at age five (preschoolers), a total of 77 adolescents (mean age: 14.35 years; SD = 1.22; 42% females) took part in this follow-up study. At baseline, both parents and teachers completed the Strengths and Difficulties Questionnaire (SDQ), covering internalizing and externalizing problems, hyperactivity, negative peer relationships, and prosocial behavior. At follow-up, participants completed a booklet of questionnaires covering socio-demographic data, MT, and sleep disturbances. Higher prosocial behavior, lower negative peer relationships, and lower internalizing and externalizing problems at age five, as rated by parents and teachers, were associated with self-reported higher MT and lower sleep disturbances at age 14. At age 14, and relative to males, females had lower MT scores and reported more sleep disturbances. The pattern of results suggests that MT traits during adolescence may have their origins in the pre-school years.

The purpose of the study was to investigate the relationships among gender, age, and self-image of adolescents attending three secondary schools in Jamaica. The relatively few studies that have been done regarding self-perceptions of these youth are not only dated but have utilized a unidimensional conceptualization of the self. The Offer Self-Image Questionnaire which employs a multidimensional construct of the self was administered to a sample of 174 Jamaican adolescents ranging in age from 14 to 18 years (M = 15.90 years, SD = 1.21). Results revealed statistically significant effects for both gender and age. Gender was found to be significant on one self-image dimension: Morals, while age differences were evident on six dimensions: Social Relationships, Morals, Sexual Attitudes, Mastery of the External World, Vocational and Educational Goals, and Emotional Health. The results in some instances were contrary to those of past research. Discussion focused on cultural socialization and other factors affecting youth in Jamaican society.

Sex differences in the rate of decline in physical activity (PA) are most pronounced during adolescence. However, once boys and girls are aligned on biological age, sex differences in the patterns of PA become attenuated. The aim of this study was to test whether biological maturation can account for sex differences in participation in PA over time from late childhood to early adolescence. A prospective cohort of children (N = 2100; 1064 boys) was followed from ages 11 to 14 yr, with repeated assessments of PA and anthropometry. Self-reported participation in organized and free play activities was used to track participation in PA. Biological age was measured using an estimate of years to attainment of peak height velocity. Mixed-effects models were used to test whether controlling for biological age attenuates the effect of chronological age and sex on PA. As expected, the rate of decline in participation in PA was greater for girls than for boys (B = -1.18, P < 0.01). In multivariable analyses, adjusting for biological age completely attenuated the effect of sex and chronological age for participation in free play activities, but not for participation in organized play. Overall, biological age was a stronger predictor of participation than chronological age. The effect of biological age on sex by chronological age differences may be specific to certain types of PA participation. Given the importance of maturation to participation in activity, it is suggested that public health strategies target biological not chronological age to prevent declines in PA during adolescence particularly when promoting habitual or lifestyle activity.

Children and adolescents who sell sex: a community study.

Adolescents who reported to have given sexual favors for payment were investigated. The sample consisted of all adolescents in the public and private school systems in Oslo, the capital in Norway (age group 14-17, response rate 94.3%, N=10,828). Adolescents who had sold sex form 1.4%, three times as many boys as girls. Half the group had done it more than 10 times. Most were under the legal age of sex in Norway (16 years) when this first happened. We found no associations with sociodemographic variables or residential area in Oslo. However, sex sale was associated with low intercourse debut age, conduct problems, alcohol problems, use of drugs (including heroin) and violent victimization. The conclusion is that a small group in the general adolescent population sells sex, and many of the clients are assumed to be homosexual or bisexual men. Adolescents who take part in these activities are often heavily involved in delinquent behaviors and use of drugs, and many probably are in a risk zone for sexually transmitted diseases (including HIV), drug abuse and a delinquent and criminal development.

Adolescents' sensitivity to children's supernatural thinking: A preparation for parenthood?

PubMed

Hernández Blasi, Carlos; Bjorklund, David F

2018-05-01

Young children often use magical explanations to account for ordinary phenomena (e.g., "The sun's not out today because it is mad"). We labeled these explanations supernatural thinking. Previous research reports that supernatural thinking attributed to preschool-age children evokes both positive affect and perceptions of helplessness from both adults and older (14-17 years old) but not younger (10-13 years old) adolescents. In this study, we asked if cues of cognitive immaturity are more influential in affecting adolescents' judgments of children than physical cues (faces). 245 adolescents aged between 10 and 17 rated pairs of children who physically and/or cognitively resembled either a 4- to 7-year-old or an 8- to 10-year-old child in three between-subject conditions (Consistent, Inconsistent, Faces-Only) for 14 traits classified into four trait dimensions (Positive Affect, Negative Affect, Intelligence, Helplessness). For both younger and older adolescents, cognitive cues had a greater influence on judgments than facial cues. However, only the older adolescents demonstrated a positive bias for children expressing immature supernatural thinking. Adopting an evolutionary developmental perspective, we interpreted this outcome in late (but not early) adolescence as preparation for potential parenthood.

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.

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 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.

Objective—To examine the prevalence of alcohol and/or other psychoactive drugs, such as marijuana and cocaine (AODs), involved in preteen trauma patients. Methods—Toxicological testing results were analyzed for 1356 trauma patients aged 10–14 years recorded in the National Pediatric Trauma Registry for the years 1990–95. Results—Of the 1356 patients who received toxicological screening at the time of admission, 116 (9%) were positive for AODs. AOD involvement increased with age. Patients with pre-existing mental disorders were nearly three times as likely as other patients to be AOD positive (23% v 8%, p<0.01). AOD involvement was more prevalent in intentional injuries and in injuries that occurred at home. Conclusions—AODs in preteen trauma are of valid concern, in particular among patients with mental disorders or intentional injuries. The role of AODs in childhood injuries needs to be further examined using standard screening instruments and representative study samples. PMID:10385826

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

Background: The concept of mental toughness (MT) has gained increasing importance among groups other than elite athletes by virtue of its psychological importance and explanatory power for a broad range of health-related behaviors. However, no study has focused so far on the psychological origins of MT. Therefore, the aims of the present study were: to explore, to what extent the psychological profiles of preschoolers aged five were associated with both (1) MT scores and (2) sleep disturbances at age 14, and 3) to explore possible gender differences. Method: Nine years after their first assessment at age five (preschoolers), a total of 77 adolescents (mean age: 14.35 years; SD = 1.22; 42% females) took part in this follow-up study. At baseline, both parents and teachers completed the Strengths and Difficulties Questionnaire (SDQ), covering internalizing and externalizing problems, hyperactivity, negative peer relationships, and prosocial behavior. At follow-up, participants completed a booklet of questionnaires covering socio-demographic data, MT, and sleep disturbances. Results: Higher prosocial behavior, lower negative peer relationships, and lower internalizing and externalizing problems at age five, as rated by parents and teachers, were associated with self-reported higher MT and lower sleep disturbances at age 14. At age 14, and relative to males, females had lower MT scores and reported more sleep disturbances. Conclusion: The pattern of results suggests that MT traits during adolescence may have their origins in the pre-school years. PMID:27605919

Objective To explore age differences in factors associated with positive sexually transmitted diseases (STD) status among a sample of African-American adolescent females. Methods Data were collected via ACASI from 701 African-American adolescent females (14–20 years) seeking services at reproductive health clinics. Adolescents provided self-collected vaginal swabs assayed using NAAT to assess the prevalence of three STDs. Results Younger adolescents (14–17 years) had significantly higher rates of STDs than older adolescents (18–20 years), but older adolescents had significantly higher levels of STD-associated risk behavior. In controlled analysis, having a casual sex partner was the only variable significantly associated with a positive STD test for younger adolescents, and prior history of STD and higher impulsivity were significantly associated with testing STD positive among older adolescents. Conclusions These findings suggest that developmentally tailored STD/HIV prevention interventions are needed for younger and older subgroups of adolescent females to help reduce their risk of infection.

Background We analysed genetic and environmental influences on self-esteem and its stability across adolescence. Methods Finnish twins born in 1983–1987 were assessed by questionnaire at ages 14y (N= 4132 twin individuals) and 17y (N=3841 twin individuals). Self esteem was measured using the Rosenberg global self-esteem scale and analyzed using quantitative genetic methods for twin data in the Mx statistical package. Results The heritability of self-esteem was 0.62 (95% CI 0.56–0.68) in 14-y-old boys and 0.40 (95% CI 0.26–0.54) in 14-y-old girls, while the corresponding estimates at age 17y were 0.48 (95% CI 0.39–0.56) and 0.29 (95% CI 0.11–0.45). Rosenberg self-esteem scores at age 14 y and 17 y were modestly correlated (r=0.44 in boys, r=0.46 in girls). In boys, the correlation was mainly (82%) due to genetic factors, with residual co-variation due to unique environment. In girls, genetic (31%) and common environmental (61%) factors largely explained the correlation. Conclusions In adolescence, self-esteem seems to be differently regulated in boys versus girls. A key challenge for future research is to identify environmental influences contributing to self-esteem during adolescence and how these factors interact with genetic influences. PMID:17537282

This study examined the cases of 557 primiparous adolescents, between the ages of 9 and 19, who gave birth at the Obstetric Clinic of the Medical School of the University of Sao Paulo, Brazil, from January 1975 to June 1980. During this period 13,961 deliveries took place, producing an adolescent pregnancy incidence of 3.9%. Based on previous work, 2 groups were established: Group I, composed of 242 women aged 9 to 16, and Group II, composed of 315 women aged 17 to 19. The greatest number of unwed mothers occurred in Group I, the younger age group (98.4%), compared to 54.3% in Group II. An important characteristic in the younger age group was lack of adequate prenatal care. In Group I only 12% received adequate prenatal care, while in Group II, 28.6% received adequate care. Clearly the greatest frequency of prematurity was in the younger group (28.1% of Group I vs. 12.4% of Group II), along with a higher rate of perinatal mortality (4.9% in Group I vs. 2.5% in Group II). Cases of eclampsia occurred more frequently in the younger adolescents (3.3% of Group I vs 1.6% of Group II), but hypertension was more prevalent among the older adolescents (35.9% in Group II vs. 22.7% in Group I). The authors conclude that during pregnancy all adolescents reach similar biologic and endocrine maturity and display similar obstetric performance. The less satisfactory performance among patients in Group I is primarily due to socioeconomic conditions, inadequate resolution of problems related to acceptance of pregnancy, lack of family support, and inadquate prenatal care. The authors believe that the risks associated with adolescent pregnancy could be substantially reduced if adolescents were better informed and received psychological support and adequate prenatal care.

Objective Despite concerns about exposure to violent media, there are few data on youth exposure to violent movies. In this study we examined such exposure among young US adolescents. Methods We used a random-digit-dial survey of 6522 US adolescents aged 10 to 14 years fielded in 2003. Using previously validated methods, we determined the percentage and number of US adolescents who had seen each of 534 recently released movies. We report results for the 40 that were rated R for violence by the Motion Picture Association of America, UK 18 by the British Board of Film Classification and coded for extreme violence by trained content coders. Results The 40 violent movies were seen by a median of 12.5% of an estimated 22 million US adolescents aged 10 to 14 years. The most popular violent movie, Scary Movie, was seen by >10 million (48.1%) children, 1 million of whom were 10 years of age. Watching extremely violent movies was associated with being male, older, nonwhite, having less-educated parents, and doing poorly in school. Black male adolescents were at particularly high risk for seeing these movies; for example Blade, Training Day, and Scary Movie were seen, respectively, by 37.4%, 27.3%, and 48.1% of the sample overall versus 82.0%, 81.0%, and 80.8% of black male adolescents. Violent movie exposure was also associated with measures of media parenting, with high-exposure adolescents being significantly more likely to have a television in their bedroom and to report that their parents allowed them to watch R-rated movies. Conclusions This study documents widespread exposure of young US adolescents to movies with extreme graphic violence from movies rated R for violence and raises important questions about the effectiveness of the current movie-rating system.

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.

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.

Personality Stability From Age 14 to Age 77 Years

PubMed Central

2016-01-01

There is evidence for differential stability in personality trait differences, even over decades. The authors used data from a sample of the Scottish Mental Survey, 1947 to study personality stability from childhood to older age. The 6-Day Sample (N = 1,208) were rated on six personality characteristics by their teachers at around age 14. In 2012, the authors traced as many of these participants as possible and invited them to take part in a follow-up study. Those who agreed (N = 174) completed a questionnaire booklet at age 77 years, which included rating themselves and asking someone who knew them well to rate them on the same 6 characteristics on which they were rated in adolescence. Each set of 6 ratings was reduced to the same single underlying factor, denoted dependability, a trait comparable to conscientiousness. Participants’ and others’ older-age personality characteristic ratings were moderately correlated with each other, and with other measures of personality and wellbeing, but correlations suggested no significant stability of any of the 6 characteristics or their underlying factor, dependability, over the 63-year interval. However, a more complex model, controlling rater effects, indicated significant 63-year stability of 1 personality characteristic, Stability of Moods, and near-significant stability of another, Conscientiousness. Results suggest that lifelong differential stability of personality is generally quite low, but that some aspects of personality in older age may relate to personality in childhood. PMID:27929341

Age at Time of Initial Sexual Intercourse and Health of Adolescent Girls.

Adolescence is characterized by marked changes in the body, psychology, and sexual behavior due to increasing production of hormones. In this review we aimed to assess the effect of age at the time of first sexual intercourse (sexarche) on the health of adolescent girls, and identify factors that might protect against early initiation of sexual relations in girls. The PubMed, Lilacs, and Google Scholar databases were searched for clinical trials, comparative studies, case-control studies, cross-sectional studies, cohort studies, multicenter studies, observational studies, meta-analyses, and systematic reviews published up to December 2014 on this theme. The search terms were: "sexual debut," "coitarche," "sexarche," and "young people," "adolescent," "unplanned pregnancy," "adolescent contraception," and "STDs." Data were extracted from 28 studies and 41 references were used to introduce the theme and to support the discussion. Sexarche has been occurring in increasingly younger girls. A young age at sexarche can lead to subsequent risky sexual behavior. Girls who have sexarche when they are 14 years old or younger are less likely to use contraception on this occasion, take more time before they start using contraception in subsequent sexual relations, are more likely to have several sex partners, have a higher risk for depression, have lower self-esteem and more episodes of repentance, and have a higher risk for a sexually transmitted disease and cervical cancer. Girls with low educational, socioeconomic, and cultural status, little parental monitoring, parental separation, and absence of religiosity tend to experience sexarche at a younger age. Adolescent girls who postpone sexarche until they are 16 years old are physically and psychologically healthier than those who have sexarche at a younger age. This suggests that providing adolescent girls with appropriate education about sexual relations might reduce the negative effect of sexual relations at a young age

Acne vulgaris commonly affects adolescents. But recent reports suggest a rising prevalence of post-adolescence acne. While there are few reports on post-adolescence acne, there are even fewer reports comparing adolescence acne and post-adolescence. Epidemiological data of adolescence (<25 years) and post-adolescence (≥25 years) acne patients diagnosed between 2004 and 2013 in a tertiary dermatology referral centre was analysed. From the pool of patients seen in 2010, 80 adolescence and 84 post-adolescence acne patients' epidemiological characteristics and treatment responses were analysed. During the 10-year study period, there was an increase in the number and proportion of acne cases. In 2004, 4447 (5.77%) of all new diagnoses made were of acne vulgaris. The proportion rose to 5723 (8.13%) in 2013. There were consistently more female than male acne patients. The proportion of post-adolescent cases remained constant at about 30% of all acne patients seen. Mean age of acne vulgaris patients decreased from 23.1 years in 2004 to 22.6 years in 2013. In the subgroup analysis, there were more males than females with adolescence acne (61.3% vs. 38.8%, P < 0.01) and more females with post-adolescence acne (69.0% vs. 31.0%, P < 0.01). Thirty-four (40.5%) post-adolescence acne patients had acne from adolescence persisting into adulthood. Comedonal acne was more prevalent in the adolescence acne patients (58.8% vs. 40.5%, P = 0.019), whereas cystic acne was more prevalent in post-adolescence patients (18.1% vs. 7.5%, P = 0.044). Systemic retinoids were more often used for treatment in the adolescence acne patients than post-adolescence acne patients (23.8% vs. 10.7%, P = 0.027). Acne predominantly affects adolescents but post-adolescence acne is not uncommon. For post-adolescence acne, females predominate over males. Inflammatory and cystic acne tends to be more predominant in post-adolescence acne patients, whereas comedonal acne is more often seen in adolescence acne

A culture-fair scale that was specifically developed to compare six self-concept areas of English and Nigerian (Yoruba) adolescents was utilized in a sample of 686 adolescents. This consisted of 314 white English and 372 Yoruba adolescents whose ages ranged between 14.9 and 10.70 years. The English adolescents were found to have significantly more positive self-concept on most of the 24 scales. The observed results were explained in the light of the sociocultural environments of the two groups of adolescents.

The aim of this study was to evaluate the metabolic syndrome (MetS) prevalence in adolescents using three different definitions for this age group. The evaluated sample consisted of 718 male and 743 female adolescents. Definitions by Cook et al., de Ferranti et al. and International Diabetes Federation (IDF) for adolescents were used to estimate the prevalence of MetS. The prevalence of MetS was 8.5, 2.5 and 1.2% by de Ferranti et al., Cook et al. and IDF definitions, respectively. High fasting glucose component had the lower prevalence whereas high triglycerides levels component was the most prevalent. In obese adolescents, the prevalence of MetS was higher. MetS classification in adolescents strongly depends on the definition chosen. Further research is required for the evaluation of the current definitions (multicentric studies), and for addition or design of new and useful criteria.

Weight loss strategies for adolescents: a 14-year-old struggling to lose weight.

PubMed

Ludwig, David S

2012-02-01

With prevalence approaching 20% in the United States, adolescent obesity has become a common problem for patients, parents, and clinicians. Obese adolescents may experience physical and psychosocial complications, as illustrated by the case of Ms K, a 14-year-old girl with a body mass index of 40. Unfortunately, the effectiveness of pediatric obesity treatment is modest in younger children and declines in older children and adolescents, and few interventions involving adolescents have produced significant long-term weight loss. Nevertheless, novel strategies to alter energy balance have shown preliminary evidence of benefit in clinical trials, including a diet focused on food quality rather than fat restriction and a lifestyle approach to encourage enjoyable physical activity throughout the day rather than intermittent exercise. Parents can have an important influence on weight-related behaviors in adolescents despite typically complicated emotional dynamics at this age, especially through the use of noncoercive methods. A key parenting practice applicable to children of all ages is to create a protective environment in the home, substituting nutritious foods for unhealthful ones and facilitating physical activities instead of sedentary pursuits. Other behaviors that may promote successful long-term weight management include good sleep hygiene, stress reduction, and mindfulness. Ultimately, the obesity epidemic can be attributed to changes in the social environment that hinder healthful lifestyle habits, and prevention will require a comprehensive public health strategy.

Young people expose themselves to potentially damaging loud sounds while leisure activities and noise induced hearing loss is diagnosed in increasing number of adolescents. Hearing and music exposure in a group of adolescents of a technical high school was assessed at the ages of: 14-15 (test) and 17-18 (retest). The aims of the current study were: (1) To compare the auditory function between test and retest; (2) to compare the musical exposure levels during recreational activities in test and retest; (3) to compare the auditory function with the musical exposure along time in a subgroup of adolescents. The participants in the test were 172 male; in the retest, this number was reduced to 59. At the test and retest the conventional and extended high frequency audiometry, transient evoked otoacoustic emissions (TEOAEs) and recreational habits questionnaire were performed. In the test, hearing threshold levels (HTLs) were classified as: Normal (Group 1), slightly shifted (Group 2), and significantly shifted (Group 3); the Musical General Exposure (MGE), categorized in: Low, moderate, high, and very high exposure. The results revealed a significant difference (P < 0.0001) between test and retest in the HTL and global amplitude of TEOAEs in Group 1, showing an increase of the HTL and a decrease TEOAEs amplitude. A subgroup of adolescents, with normal hearing and low exposure to music in the test, showed an increase of the HTL according with the categories of MGE in the retest. To implement educational programs for assessing hearing function, ear vulnerability and to promote hearing health, would be advisable.

Analyses of children and young people mortality continue to be an important component of health monitoring of this population. Such analyses provide the basis to assess the overall trends, the structure of the causes of death over longer periods, and the differences between Poland and other countries. The purpose of the current study is to present the current status and the direction of changes since 2000 with regard to the level and underlying causes of mortality in children and adolescents aged 1-19 years in Poland on the background of statistics for leading European countries. Interactive databases available online: the National Demographic Database provided by the Central Statistical Office and the International WHO-MDB Database were used. Poland, constantly belonging to Eur-B category, was compared with the combined group of 27 leading countries, classified as a very low total mortality group (Eur-A) according to WHO. Linear trends of overall and cause-specific mortality in 2000-2013 were estimated. The causes of death have been presented according to the main classes of the 10th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-10). External and other causes were adopted as the two principal categories. In 2015, 1471 deaths of persons aged 1-19 were recorded in Poland (19.9 per 100 000, 25.4 and 14.2 for boys and girls, respectively). Changes in children and adolescents mortality by age have a non-linear nature (U-shaped), and the lowest level is recorded at the age of 5-9 years. According to 2014 data, 50.2% of deaths of children and adolescents aged 1-19 years occurred due to external causes, including non-intentional and intentional ones. This percentage increased from 18.4% in the 1-4 age group to 68.6% at the age of 15-19 years. Apart from external causes, the dominating causes of death are malignant neoplasms, congenital defects, or nervous system and respiratory system diseases. The ranking of those

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.

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.

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.

Recent research has shown that the Fitkids Treadmill Test (FTT) is a valid and reproducible exercise test for the assessment of aerobic exercise capacity in children and adolescents who are healthy. The study objective was to provide sex- and age-related normative values for FTT performance in children and adolescents who were healthy, developing typically, and 6 to 18 years of age. This was a cross-sectional, observational study. Three hundred fifty-six children and adolescents who were healthy (174 boys and 182 girls; mean age=12.9 years, SD=3.7) performed the FTT to their maximal effort to assess time to exhaustion (TTE). The least-mean-square method was used to generate sex- and age-related centile charts (P3, P10, P25, P50, P75, P90, and P97) for TTE on the FTT. In boys, the reference curve (P50) showed an almost linear increase in TTE with age, from 8.8 minutes at 6 years of age to 16.1 minutes at 18 years of age. In girls, the P50 values for TTE increased from 8.8 minutes at 6 years of age to 12.5 minutes at 18 years of age, with a plateau in TTE starting at approximately 10 years of age. Youth who were not white were underrepresented in this study. This study describes sex- and age-related normative values for FTT performance in children and adolescents who were healthy, developing typically, and 6 to 18 years of age. These age- and sex-related normative values will increase the usefulness of the FTT in clinical practice. © 2016 American Physical Therapy Association.

Investing in very young adolescents' sexual and reproductive health

PubMed Central

Igras, Susan M.; Macieira, Marjorie; Murphy, Elaine; Lundgren, Rebecka

2014-01-01

Very young adolescents (VYAs) between the ages of 10 and 14 represent about half of the 1.2 billion adolescents aged 10–19 in the world today. In lower- and middle-income countries, where most unwanted pregnancies, unsafe abortions, maternal deaths and sexually transmitted infections occur, investment in positive youth development to promote sexual and reproductive health (SRH) is increasing. Most interventions, though, focus on older adolescents, overlooking VYAs. Since early adolescence marks a critical transition between childhood and older adolescence and adulthood, setting the stage for future SRH and gendered attitudes and behaviours, targeted investment in VYAs is imperative to lay foundations for healthy future relationships and positive SRH. This article advocates for such investments and identifies roles that policy-makers, donors, programme designers and researchers and evaluators can play to address the disparity. PMID:24824757

2017-06-01

There is limited research on clinical features related to age of presentation of the Attenuated Psychosis Syndrome in children and adolescents (CAD). Based on findings in CAD with psychosis, we hypothesized that an older age at presentation of Attenuated Psychosis Syndrome would be associated with less severe symptoms and better psychosocial functioning than presentation in childhood or younger adolescence. Ninety-four CAD (age 9-18) meeting Attenuated Psychosis Syndrome criteria participated in the study. The sample was divided and compared according to the age of presentation of Attenuated Psychosis Syndrome (9-14 vs 15-18 years). The predictive value of age of Attenuated Psychosis Syndrome presentation was investigated using receiver operating characteristic (ROC)-curve calculations. The two Attenuated Psychosis Syndrome groups were homogeneous in terms of gender distribution, IQ scores and comorbid diagnoses. Older Attenuated Psychosis Syndrome patients showed better functioning and lower depressive scores. ROC curves revealed that severity of functional impairment was best predicted using an age of presentation cut-off of 14.9 years for social functioning and 15.9 years for role functioning. This study partially confirmed our hypothesis; older age at presentation of Attenuated Psychosis Syndrome was associated with less functional impairment, but age was not associated with psychotic symptoms.

There is increasing recognition that socio-cognitive skills, such as moral reasoning (MR), are affected in a wide range of developmental and neuropsychological conditions. However, the lack of appropriate measures available to neuropsychologists poses a challenge for the direct assessment of these skills. This study sought to explore age-related changes in MR using an innovative visual tool and examine the developmental sensitivity of the task. To address some of the methodological limitations of traditional measures of MR, a novel, visual task, the Socio-Moral Reasoning Aptitude Level (So-Moral), was used to evaluate MR in 216 healthy participants aged 6-20 years. The findings show a linear increase in MR from childhood to late adolescence with significant group differences between childhood (6-8 years) and preadolescence (9-11 years), and between early adolescence (12-14 years) and middle adolescence (15-17 years). Interpreted in light of current brain development research, the results highlight age-related changes in MR that offer insight into typical MR development and opportunities for comparisons with clinical populations. The findings also provide evidence of the potential of the So-Moral as a developmentally appropriate measure of MR throughout childhood and adolescence.

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

Riechard, Donald E.; McGarrity, Jean

1994-01-01

In this exploratory study, perceptions of relative risk held by 120 early adolescents (11-14 years) were examined for 10 hazards: wild animals, fire, nuclear energy, pollution, storms, war, car accidents, people, no food, and drugs. Dissonance was found between perceptions of risk and computed risk associated with factual data. (LZ)

Experience with providers shapes the quality of adolescent health services, including voluntary medical male circumcision (VMMC). This study examined the perceived quality of in-service communication and counseling during adolescent VMMC services. A postprocedure quantitative survey measuring overall satisfaction, comfort, perceived quality of in-service communication and counseling, and perceived quality of facility-level factors was administered across 14 VMMC sites in South Africa, Tanzania, and Zimbabwe. Participants were adolescent male clients aged 10-14 years (n = 836) and 15-19 years (n = 457) and completed the survey 7 to 10 days following VMMC. Adjusted prevalence ratios (aPRs) were estimated by multivariable modified Poisson regression with generalized estimating equations and robust variance estimation to account for site-level clustering. Of 10- to 14-year-olds and 15- to 19-year-olds, 97.7% and 98.7%, respectively, reported they were either satisfied or very satisfied with their VMMC counseling experience. Most were also very likely or somewhat likely (93.6% of 10- to 14-year olds and 94.7% of 15- to 19-year olds) to recommend VMMC to their peers. On a 9-point scale, the median perceived quality of in-service (counselor) communication was 9 (interquartile range [IQR], 8-9) among 15- to 19-year-olds and 8 (IQR, 7-9) among 10- to 14-year-olds. The 10- to 14-year-olds were more likely than 15- to 19-year-olds to perceive a lower quality of in-service (counselor) communication (score <7; 21.5% vs. 8.2%; aPR, 1.61 [95% confidence interval, 1.33-1.95]). Most adolescents were more comfortable with a male rather than female counselor and provider. Adolescents of all ages wanted more discussion about pain, wound care, and healing time. Adolescents perceive the quality of in-service communication as high and recommend VMMC to their peers; however, many adolescents desire more discussion about key topics outlined in World Health Organization guidance.

The use of melatonin in Swedish children and adolescents--a register-based study according to age, gender, and medication of ADHD.

2015-07-01

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.

Many risk behaviours in adolescence are socially patterned. However, it is unclear to what extent socioeconomic position (SEP) influences adolescent drinking in various parts of Europe. We examined how alcohol consumption is associated with parental SEP and adolescents' own SEP among students aged 14-17 years. Cross-sectional data were collected in the 2013 SILNE study. Participants were 8705 students aged 14-17 years from 6 European cities. The dependent variable was weekly binge drinking. Main independent variables were parental SEP (parental education level and family affluence) and adolescents' own SEP (student weekly income and academic achievement). Multilevel Poisson regression models with robust variance and random intercept were fitted to estimate the association between adolescent drinking and SEP. Prevalence of weekly binge drinking was 4.2% (95%CI = 3.8-4.6). Weekly binge drinking was not associated with parental education or family affluence. However, weekly binge drinking was less prevalent in adolescents with high academic achievement than those with low achievement (PR = 0.34; 95%CI = 0.14-0.87), and more prevalent in adolescents with >€50 weekly income compared to those with ≤€5/week (PR = 3.14; 95%CI = 2.23-4.42). These associations were found to vary according to country, but not according to gender or age group. Across the six European cities, adolescent drinking was associated with adolescents' own SEP, but not with parental SEP. Socio-economic inequalities in adolescent drinking seem to stem from adolescents' own situation rather than that of their family.

Harville, Emily W.; Madkour, Aubrey Spriggs; Xie, Yiqiong

2012-01-01

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

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

Eating disorder symptom trajectories in adolescence: effects of time, participant sex, and early adolescent depressive symptoms

PubMed Central

2013-01-01

Background Adolescence is a period of developmental risk for eating disorders and eating disorder symptoms. This study aimed to describe the prevalence and trajectory of five core eating disorder behaviours (binge eating, purging, fasting, following strict dietary rules, and hard exercise for weight control) and a continuous index of dietary restraint and eating, weight and shape concerns, in a cohort of male and female adolescents followed from 14 to 20 years. It also aimed to determine the effect of early adolescent depressive symptoms on the prevalence and trajectory of these different eating disorder symptoms. Participants (N = 1,383; 49% male) were drawn from the Western Australian Pregnancy Cohort (Raine) Study, a prospective cohort study that has followed participants from pre-birth to age 20 years. An adapted version of the Eating Disorder Examination-Questionnaire was used to assess eating disorder symptoms at ages 14, 17 and 20 years. The Beck Depression Inventory for Youth was used to assess depressive symptoms at age 14. Longitudinal changes in the prevalence of eating disorder symptoms were tested using generalised estimating equations and linear mixed models. Results Symptom trajectories varied according to the eating disorder symptom studied, participant sex, and the presence of depressive symptoms in early adolescence. For males, eating disorder symptoms tended to be stable (for purging, fasting and hard exercise) or decreasing (for binge eating and global symptom scores) from 14 to 17 years, and then stable to 20 years. For females, fasting and global symptom scores increased from age 14 to peak in prevalence at age 17. Rates of binge eating in females were stable from age 14 to age 17 and increased significantly thereafter, whilst rates of purging and hard exercise increased from age 14 to age 17, and then remained elevated through to age 20. Depressive symptoms at age 14 impacted on eating disorder symptom trajectories in females, but not in

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.

Resilience has been characterized as a defensive factor against the refinement of mental health problems. This study adapted the Connor-Davidson Resilience Scale (Kh-CD-RISC10) for use in Khmer adolescents and subsequently investigates its psychometric properties. Using stratified random sampling, this cross-sectional study sampled Cambodian adolescents from high schools selected randomly within three provinces (Phnom Penh, Battambang and Mondulkiri)-location (rural, urban) combinations. Parallel analysis was used to identify the number of component(s), and the structure of the single factor was subsequently explored using principal axis factoring. A confirmatory factor analysis was then performed to establish the fit of the Kh-CD-RISC10 to another sample. To assess convergent validity, the factor scores of the Khmer version of Connor-Davidson Resilience Scale were categorized into three levels, and then the general negative affectivity (GNA) and physiological hyperarousal (PH) scales (derived from the DASS 21) were compared among the three resilience groups. Of the 798 participants who responded (responded rate = 82.26 %), 440 (41.23 %) were female and the age ranged from 14 to 24 years old (mean = 17.36, SD = 1.325). The internal consistency of the Khmer 10-item CD-RISC was also shown to be high in Cambodian adolescents (Cronbach's alpha = 0. 82). Confirmatory factor analysis revealed the single factor model fit data adequately (χ(2) = 100.103, df = 35, p < 0.001, CFI = 0.9484, RMSEA = 0.0384). We found that there were significant differences in both General Negative affectivity and Physiological Hyperarousal among the three resilience groups (FGNA = 12. 84, df = 2, p < 0.001; FPH = 13. 01, df = 2, p < 0.001). The results from the present study indicate that the Khmer version of CD-RISC shows good psychometric properties in Cambodian adolescents. Our result confirms that a single dimension underlay the 10 items on the CD

Sexual and Contraceptive Behaviors among Adolescents Requesting Emergency Contraception.

2016-12-01

Unintended pregnancy rates in the United States remain high among adolescents. Emergency contraception (EC) provides the only option for pregnancy prevention after unprotected sex. To better define the population of adolescents who request and use EC pills, we performed a post hoc analysis of an over-the-counter simulation study of EC pills. Teen reproductive health clinics in 5 cities. Adolescents between the ages of 13 and 17 years who requested EC. Single-tablet levonorgestrel 1.5 mg. We calculated the correlations between age and baseline sexual and contraceptive behaviors. χ 2 Tests were used to compare behaviors of first-time and repeat EC users. Overall, the most commonly reported contraceptive methods ever used were condoms, oral contraceptives, none, and withdrawal; the most common method ever used in each age group was no method for 13- to 14-year-olds and condom for 15-, 16-, and 17-year-olds. The percentage of participants who had never used contraception before requesting EC decreased with age (53% [20/28] of 13- to 14-year-olds vs 15% [10/65] of 17-year-olds). First-time EC users were more likely to report no previous contraceptive use compared with repeat EC users (42% [88/208] vs 10% [13/135]; P < .001). Regardless of age, the most commonly reported reason for requesting EC was nonuse of any contraceptive method (ie, "unprotected sex"). Adolescents who requested EC most commonly reported ever-use of contraceptive methods that rely on user adherence or no method at all, with younger adolescents more likely than older adolescents to have used no previous method. The provision of EC presents an opportunity to provide education and access to highly effective, long-term contraceptive methods.

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

Laboratory social stress tests involving public speaking challenges are widely used for eliciting an acute stress response in older children, adolescents, and adults. Recently, a group protocol for a social stress test (the Trier Social Stress Test for Groups, TSST-G) was shown to be effective in adults and is dramatically less time-consuming and resource-intensive compared to the single-subject version of the task. The present study sought to test the feasibility and effectiveness of an adapted group public speaking task conducted with a racially diverse, urban sample of U.S. adolescents (N = 191; 52.4% female) between the ages of 11 and 18 (M = 14.4 years, SD = 1.93). Analyses revealed that this Group Public Speaking Task for Adolescents (GPST-A) provoked a significant increase in cortisol production (on average, approximately 60% above baseline) and in self-reported negative affect, while at the same time avoiding excessive stress responses that would raise ethical concerns or provoke substantial participant attrition. Approximately 63.4% of participants exhibited an increase in cortisol levels in response to the task, with 59.2% of the total sample showing a 10% or greater increase from baseline. Results also suggested that groups of 5 adolescents might be ideal for achieving more uniform cortisol responses across various serial positions for speech delivery. Basal cortisol levels increased with age and participants belonging to U.S. national minorities tended to have either lower basal cortisol or diminished cortisol reactivity compared to non-Hispanic Whites. This protocol facilitates the recruitment of larger sample sizes compared to prior research and may show great utility in answering new questions about adolescent stress reactivity and development.

Chiam, H K

1987-01-01

Malaysian adolescents, like their Western counterparts, undergo rapid growth and development. It is hypothesized that self-concept improves as adolescents mature and become more adjusted to the changes. This study therefore sought to ascertain whether the self-concept changes with age, not only in the global sense but in the various components of the self-concept. The Tennessee Self-Concept Scale and the Brookover Scale of Academic Ability were administered to 375 adolescent boys, ranging in age from 14.7 to 17.0 years, and to 289 adolescent girls, ranging in age from 14.4 to 17.2 years. The findings show that the self-concept of adolescent boys changes with age in the direction predicted. The trend is less obvious and less consistent for girls.

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 global epidemiology of adolescents living with HIV: time for more granular data to improve adolescent health outcomes.

Slogrove, Amy L; Sohn, Annette H

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.

Dietary sugar intake, particularly added sugar and sugar-sweetened beverages, has received worldwide attention recently. Investigation of dietary behaviors may facilitate understanding of dietary sugar intakes of children and adolescents. However, the relationship between dietary sugar intake and dietary behaviors in the Korean population has not been investigated. Thus, this study aimed to estimate dietary sugar intake and food sources according to sex as well as examine the relationship of dietary sugar intake with frequent snacking and dietary patterns among Korean children and adolescents. We pooled data from five studies involving Korean children and adolescents conducted from 2002 to 2011. A total of 2,599 subjects aged 9-14 years were included in this study. Each subject completed more than 3 days of dietary records. Mean daily total sugar intake was 46.6 g for boys and 54.3 g for girls. Compared with boys, girls showed higher sugar intakes from fruits (7.5 g for boys and 8.8 g for girls; P = 0.0081) and processed foods (27.9 g for boys and 34.9 g for girls; P < 0.0001). On average, 95.4% of boys and 98.8% of girls consumed snacks during the study period, and total sugar intake showed a significantly increasing trend with increasing energy intake from snacks ( P < 0.0001 for both sexes). Two dietary patterns were identified by cluster analysis: Traditional and Westernized patterns. Total sugar intake was higher in the Westernized pattern (56.2 g for boys and 57.2 g for girls) than in the Traditional pattern (46.5 g for boys and 46.3 g for girls). These results suggest that multilateral and practical development of a nutrition education and intervention program that considers dietary behaviors as well as absolute sugar intake is required to prevent excessive sugar intake in Korean children and adolescents.

Adolescent Health Implications of New Age Technology.

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.

Resting heart rate and the development of antisocial behavior from age 9 to 14: genetic and environmental influences.

PubMed

Baker, Laura A; Tuvblad, Catherine; Reynolds, Chandra; Zheng, Mo; Lozano, Dora Isabel; Raine, Adrian

2009-01-01

The genetic and environmental basis of a well-replicated association between antisocial behavior (ASB) and resting heart rate was investigated in a longitudinal twin study, based on two measurements between the ages of 9 and 14 years. ASB was defined as a broad continuum of externalizing behavior problems, assessed at each occasion through a composite measure based on parent ratings of trait aggression, delinquent behaviors, and psychopathic traits in their children. Parent ratings of ASB significantly decreased across age from childhood to early adolescence, although latent growth models indicated significant variation and twin similarity in the growth patterns, which were explained almost entirely by genetic influences. Resting heart rate at age 9-10 years old was inversely related to levels of ASB but not change patterns of ASB across age or occasions. Biometrical analyses indicated significant genetic influences on heart rate during childhood, as well as ASB throughout development from age 9 to 14. Both level and slope variation were significantly influenced by genetic factors. Of importance, the low resting heart rate and ASB association was significantly and entirely explained by their genetic covariation, although the heritable component of heart rate explained only a small portion (1-4%) of the substantial genetic variance in ASB. Although the effect size is small, children with low resting heart rate appear to be genetically predisposed toward externalizing behavior problems as early as age 9 years old.

2015-01-01

Although neighbourhood factors have been proposed as determinants of adolescent behaviour, few studies document their relative etiological importance. We investigated the relationship between neighbourhood crime and cannabis use in a nationally representative sample of Canadian adolescents. Data from the 2009/10 Canadian Health Behaviour in School-aged Children (HBSC) survey (n=9134 14- and 15-year-olds) were combined with area-level data on crime and socioeconomic status of the neighbourhood surrounding the schools (n=218). Multilevel logistic regression analyses showed that after individual and contextual differences were held constant, neighbourhood crime related to cannabis use (OR 1.29, CI 1.12-1.47 per 1.0 SD increase in crime). This association was not moderated by parental support nor having cannabis-using friends. The amount of explained variance at the neighbourhood level was 19%. Neighbourhood crime is an important factor to consider when designing interventions aimed at reducing adolescent cannabis use. Interventional research should examine the effectiveness of community-based interventions that target adolescents through parents and peers. Copyright © 2014 Elsevier Ireland Ltd.

2008-10-01

This study assesses whether the stresses associated with parenting a child are indirectly related to adolescent self-concept through parenting behaviors. We examined longitudinal associations among mothers' and fathers' parenting stress at age 10, children's perceptions of parenting at age 10, and adolescents' self-concept at age 14 in 120 European American families. Mothers' and fathers' parenting stress was related to children's perceptions of acceptance and psychologically controlling behavior, and psychologically controlling behavior (and lax control for fathers) was related to adolescent self-concept. We further examined which domains of parenting stress and perceived parenting behaviors were associated with adolescents' scholastic competence, social acceptance, physical appearance, and behavioral conduct. Parenting stress was related to specific parenting behaviors, which were, in turn, related to specific domains of self-concept in adolescence. Parenting stress appears to exert its effects on early adolescent self-concept indirectly through perceived parenting behavior. Copyright 2008 APA, all rights reserved.

This study examined whether consuming energy drinks at the age of 14 predicted substance use at 16. We followed 621 youths from an area of Switzerland who completed a longitudinal online survey in both 2012 and 2014 when they were 14 and 16 years of age. At 14, participants, who were divided into nonenergy drink users (n = 262), occasional users (n = 183) and regular users (n = 176), reported demographic, health-related and substance use data. Substance use at 16 was assessed through logistic regression using nonusers as the reference group and controlling for significant variables at 14. At the bivariate level, energy drink consumption was associated with substance use at both 14 and 16. Energy drink consumers were also more likely to be male, older, less academic, sleep less on schooldays and live in an urban area. In the multivariate analysis, smokers, alcohol misusers and cannabis users at the age of 16 were significantly more likely to have been regular energy drink users at the age of 14. Consuming energy drinks at 14 years of age predicted using legal and illegal substances at 16. Health providers should screen young adolescents for energy drink use and closely monitor weekly users. ©2016 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

Adolescence is the period of development that begins at puberty and ends in early adulthood. Most commonly, adolescence is divided into three developmental periods: early adolescence (10-14 years of age), late adolescence (15-19 years of age), and young adulthood (20-24 years of age). Adolescence is marked by physical and sexual maturation, social and economic independence, development of identity, acquisition of skills needed to carry out adult relationships and roles, and the capacity for abstract reasoning. Adolescence is characterized by a rapid pace of growth that is second only to that of infancy. Nutrition and the adolescent transition are closely intertwined, since eating patterns and behaviors are influenced by many factors, including peer influences, parental modeling, food availability, food preferences, cost, convenience, personal and cultural beliefs, mass media, and body image. Here, we describe the physiology, metabolism, and nutritional requirements for adolescents and pregnant adolescents, as well as nutrition-related behavior and current trends in adolescent nutrition. We conclude with thoughts on the implications for nutrition interventions and priority areas that would require further investigation. © 2017 New York Academy of Sciences.

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.

Acne vulgaris in early adolescent boys. Correlations with pubertal maturation and age.

1991-02-01

To assess the prevalence and severity of acne vulgaris in young adolescent boys, we studied 219 black and 249 white boys in fifth through ninth grades in Cincinnati, Ohio. The mean age was 12.2 +/- 1.4 years, with a range of 9 to 15 years. Pubertal maturation was scored as Tanner pubic hair stages (PH I to V) and pubertal stages (PS I to IV) that included testicular volume assessment. Acne was scored by number of comedonal (open plus closed comedones) and inflammatory (papules plus pustules) lesions. Comedonal and inflammatory lesions were analyzed separately and evaluated both as numerical scores and as grades (1, less than or equal to 10 lesions; 2, 11 to 25 lesions; and 3, greater than or equal to 26 lesions). Grades 2 and 3 were considered clinically significant acne. Acne became progressively more severe with advancing maturity. Mean acne scores correlated better with PS and pubic hair than with age. Black subjects were more mature than white subjects. Black boys in PSI and II had significantly more comedones than white boys; white boys had significantly more inflammatory lesions at PS I and III. Clinically significant comedonal acne was already present in PS I and occurred in 100% of boys in PS IV. In contrast, no boys at PS I and only 50% at PS IV had significant inflammatory acne. Midfacial acne dominated. We concluded that acne prevalence and severity correlate well with advancing pubertal maturation in young adolescent boys. Comedonal acne was more frequent and severe than inflammatory disease. Awareness of the extent and severity of acne in preadolescents and young adolescents may ultimately provide rationale for early intervention and thus prevention of severe acne vulgaris.

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.

Risk behaviors in adolescents can lead to serious disorders, therefore the objectives of this work are to characterize the lifestyles of teenagers about substance use, sex, and road safety, and to meet socio-demographic factors associated with these. A cross-sectional, descriptive and correlational study was conducted with 204 school-age-children from 12 to 17 years, in 2013. They were given a validated questionnaire about sociodemographic, family functioning, and lifestyles such as substance abuse, sexual intercourse and road safety. A descriptive and multivariate analysis was performed by using multiple linear regression in the case of quantitative dependent variables, and binary logistic regression models in the case of binary categories. Data analysis was based on SPSS 20.0, with a significance level of p<0.05. 32.4% of students had smoked, and 61.3% had drunk alcohol. 26% of adolescent between 14-17 years had sexual intercourse; the average age of the first sexual intercourse was 14.9 years. 85.2% used condoms. 94.6% respected traffic signs, 77.5% used to wear a seat belt and 81.9% a helmet. Family functioning, as protective factor, was the variable more frequently associated to risk behaviour: smoking (OR=7.06, p=.000), alcohol drinking (OR=3.97, p=.008), sexual intercourse (OR=3.67, p=.041), and road safety (β=1.82, p=.000). According the results, age, gender and family functioning are the main factors associated with the adoption of risk behaviors. This information is important for the development of public health policies, for instance health promotion at schools. Copyright © 2016 Elsevier España, S.L.U. All rights reserved.

To guide the development of adolescent health training and the planning of future services, accurate data describing health service use by adolescents and young adults are needed. To describe admission rates for adolescents (12-17 years) and young adults (age 18 years and over) attending a specialist children's hospital over an 8-year period. Specific objectives were to describe the (i) proportion of adolescents and young adults admitted under different specialties; (ii) age range, with emphasis on those 18 years and over; and (iii) proportion of patients admitted to the general adolescent ward. Data on adolescent and young adult admissions to Princess Margaret Hospital (PMH) were collected prospectively from July 2000 to June 2008. Adolescents and young adults accounted for one fifth (range 18-22%) of all admissions to PMH. Over the 8-year period, the number of adolescent and young adult admissions increased from 3935 (54% males) to 4967 (56% males) per year. The proportion admitted to the general adolescent ward ranged from 22% to 36%. The three specialties admitting the most adolescents and young adults were General Surgery (11-13%), Orthopaedics (11-13%) and Oncology/Haematology (10-14%). The age range was: 12-14 years (57-67%); 15-17 (30-39%); 18+ (2-5%). At least 15 patients aged 20 or over were admitted each year, mostly for Dental or Plastic Surgery. Adolescent and young adult health is part of the core business of paediatrics. This should be reflected in the planning of future paediatric services. All trainees require some basic training, regardless of heir specialty area.

To determine the seroprevalence of hepatitis A (HAV) in children and adolescents aged 1 to 14 years, and to identify factors associated with a history of infection. This was a cross-sectional epidemiological study, conducted form February to August 2006 in the city of Curitiba, Paraná, Brazil, and the surrounding municipalities (Greater Curitiba). Laboratory analysis comprised qualitative assay for total HAV antibodies in whole blood samples. A total of 901 children and adolescents were recruited for the study. Age distribution was as follows: 1 to 4 years, n = 237 (26.3%); 5 to 9 years, n = 313 (34.7%); and 10 to 14 years, n = 351 (39%). The global rate of seroprevalence was 19.8%, and seroprevalence rates by age group were 3%, 21.1% and 29.9% respectively (p < 0.01). Multivariate analysis demonstrated that the following factors, in combination, had a positive association with the prevalence rate of antibodies against HAV in the study population: age groups 5 to 9 and 10 to 14 years, living in a household with more than one inhabitant per room, shared eating area and low per capita income. The results show a low prevalence of antibodies against HAV, which justifies the use of prophylactic measures, including early vaccination.

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.

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

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

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.

Characteristics of self-harm differ across ages, but there is little work identifying age-related differences in younger people. Young people entering adolescence face emotionally and developmentally different challenges to those entering adulthood. This study investigates how Emergency Department (ED) presentations and management of self-harm differ through adolescence and early adulthood. 3782 consecutive self-harm episodes involving 2559 people aged 12-25 years were identified from an existing database of Leeds ED attendances from 2004 to 2007. Odds ratios for each of four age bands were compared to the remaining young people. The female to male ratio was 6.3:1 at 12-14 years old, decreasing with successive age groups to 1.2:1 at 22-25 years old. Self-poisoning was commoner in those under 18 years old. 18-25 year olds were more likely to self-poison with prescribed medications, mixed overdoses, alcohol or recreational drugs. 18-25 year olds more often required medical treatment for the effects of the self-harm. 12-14 year olds were more often seen urgently by ED medical staff and offered high intensity mental health aftercare. Repetition of self-harm was commonest in 12-14 year olds, although multiple repetition of self-harm was commonest in 22-25 year olds. Data were not collected on whether the aftercare offered was received. The study sample included hospital attenders only. The large excess of females over males in young people's self-harm is only true at the younger age range. Older adolescents present with more severe acts of self-harm, yet receive the lowest intensity of assessment and after care. Copyright © 2016 Elsevier B.V. All rights reserved.

While altered foot arch characteristics (high or low) are frequently assumed to influence lower limb biomechanics and are suspected to be a contributing factor for injuries, the association between arch characteristics and lower limb running biomechanics in children is unclear. Therefore, the aim of this study was to investigate the relationship between a dynamically measured arch index and running biomechanics in healthy children. One hundred and one children aged 10-14 years were included in this study and underwent a biomechanical investigation. Plantar distribution (Novel, Emed) was used to determine the dynamic arch index and 3D motion capture (Vicon) to measure running biomechanics. Linear mixed models were established to determine the association between dynamic arch index and foot strike patterns, running kinematics, kinetics and temporal-spatial outcomes. No association was found between dynamic arch index and rate of rearfoot strikes (p = 0.072). Of all secondary outcomes, only the foot progression angle was associated with the dynamic arch index (p = 0.032) with greater external rotation in lower arched children. Overall, we found only few associations between arch characteristics and running biomechanics in children. However, altered foot arch characteristics are of clinical interest. Future studies should focus on detailed foot biomechanics and include clinically diagnosed high and low arched children. Copyright © 2018 Elsevier B.V. All rights reserved.

Importance Combination antiretroviral therapy (cART) initiated within several weeks of HIV infection in adults limits proviral reservoirs that preclude HIV cure. Biomarkers of restricted proviral reservoirs may aid in the monitoring of HIV remission or cure. Objectives To quantify peripheral blood proviral reservoir size in perinatally HIV-infected adolescents and to identify correlates of limited proviral reservoirs. Design, Setting, and Participants A cross-sectional study including 144 perinatally HIV-infected (PHIV+) youth (median age: 14.3 years), enrolled in the US-based Pediatric HIV/AIDS Cohort Study, on durable (median: 10.2 years) cART, stratified by age at virologic control. Main Outcome and Measures The primary endpoint was peripheral blood mononuclear cell (PBMC) proviral load following virologic control at different ages. Correlations between proviral load and markers of active HIV production (HIV-specific antibodies, 2-long terminal repeat (2-LTR) circles), and markers of immune activation and inflammation were also assessed. Results Proviral reservoir size was markedly reduced in the PHIV+ youth who achieved virologic control by age 1 year (4.2 [interquartile range, 2.6-8 6] copies per 1 million PBMCs) compared to those who achieved virologic control between 1-5 years of age (19.4 [interquartile range, 5.5-99.8] copies per 1 million PBMCs) or after age 5 years (−(70.7 [interquartile range, 23.2-209.4] copies per 1 million PBMCs; P < .00l). A proviral burden <10 copies/million PBMCs was measured in 11 (79%), 20 (40%), and 13 (18%) participants with virologic control at ages <1 year, 1-5 years, and >5 years, respectively (p<0.001). Lower proviral load was associated with undetectable 2-LTR circles (p<0.001) and HIV negative or indeterminate serostatus (p<0.001), but not with concentrations of soluble immune activation markers CD14 and CD163. Conclusions and Relevance Early effective cART along with prolonged virologic suppression after perinatal HIV

Developmental changes in parent-child communication throughout adolescence.

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.

Subjection to sexual harassment is associated with a number of negative outcomes, such as internalizing and externalizing symptoms and a disinclination to attend school. Among adolescents, sexual harassment may increase with both their emerging sexual desires and increased socializing in mixed-gender peer groups during early adolescence. We set out to study the possible associations between normative and risk-taking sexual behavior and subjection to sexual harassment among adolescents between the ages of 14 and 18 years. The informants included 90,953 boys and 91,746 girls, with a mean (SD) age of 16.3 (1.2) years, who responded to a classroom survey (School Health Promotion Study 2010-2011) in Finland. We found that even early steps in romantic and erotic experiences were associated with experiences of sexual harassment. The more advanced the adolescents' sexual experiences were, the more commonly they reported differing experiences of sexual harassment. These associations were particularly strong among the girls. Among the sexually active adolescents, the more partners the adolescents had for intercourse, the more commonly they reported experiences of sexual harassment. Adolescents actively interested in romantic and sexual relationships may socialize in contexts where sexual harassment is more likely to occur. They may be more sensitive to sexual cues than their non-interested peers, or sexual harassment may be a traumatic experience predisposing adolescents to risk-taking sexual behavior as a form of acting out. A double standard regarding the appropriate expression of sexuality received some support in our data. Copyright © 2017 Elsevier Ltd. All rights reserved.

This study assesses whether the stresses associated with parenting a child are indirectly related to adolescent self-concept through parenting behaviors. We examined longitudinal associations among mothers’ and fathers’ parenting stress at age 10, children’s perceptions of parenting at age 10, and adolescents’ self-concept at age 14 in 120 European American families. Mothers’ and fathers’ parenting stress was related to children’s perceptions of acceptance and psychologically controlling behavior, and psychologically controlling behavior (and lax control for fathers) was related to adolescent self-concept. We further examined which domains of parenting stress and perceived parenting behaviors were associated with adolescents’ scholastic competence, social acceptance, physical appearance, and behavioral conduct. Parenting stress was related to specific parenting behaviors, which were, in turn, related to specific domains of self-concept in adolescence. Parenting stress appears to exert its effects on early adolescent self-concept indirectly through perceived parenting behavior. PMID:18855511

BACKGROUND/OBJECTIVES Dietary sugar intake, particularly added sugar and sugar-sweetened beverages, has received worldwide attention recently. Investigation of dietary behaviors may facilitate understanding of dietary sugar intakes of children and adolescents. However, the relationship between dietary sugar intake and dietary behaviors in the Korean population has not been investigated. Thus, this study aimed to estimate dietary sugar intake and food sources according to sex as well as examine the relationship of dietary sugar intake with frequent snacking and dietary patterns among Korean children and adolescents. SUBJECTS/METHODS We pooled data from five studies involving Korean children and adolescents conducted from 2002 to 2011. A total of 2,599 subjects aged 9-14 years were included in this study. Each subject completed more than 3 days of dietary records. RESULTS Mean daily total sugar intake was 46.6 g for boys and 54.3 g for girls. Compared with boys, girls showed higher sugar intakes from fruits (7.5 g for boys and 8.8 g for girls; P = 0.0081) and processed foods (27.9 g for boys and 34.9 g for girls; P < 0.0001). On average, 95.4% of boys and 98.8% of girls consumed snacks during the study period, and total sugar intake showed a significantly increasing trend with increasing energy intake from snacks (P < 0.0001 for both sexes). Two dietary patterns were identified by cluster analysis: Traditional and Westernized patterns. Total sugar intake was higher in the Westernized pattern (56.2 g for boys and 57.2 g for girls) than in the Traditional pattern (46.5 g for boys and 46.3 g for girls). CONCLUSIONS These results suggest that multilateral and practical development of a nutrition education and intervention program that considers dietary behaviors as well as absolute sugar intake is required to prevent excessive sugar intake in Korean children and adolescents.

Implicit self-esteem has remained an active research topic in both the areas of implicit social cognition and self-esteem in recent decades. The purpose of this study is to explore the development of implicit self-esteem in adolescents. A total of 599 adolescents from junior and senior high schools in East China participated in the study. They ranged in age from 11 to 18 years with a mean age of 14.10 (SD = 2.16). The degree of implicit self-esteem was assessed using the Implicit Association Test (IAT) with the improved D score as the index. Participants also completed the Rosenberg Self-Esteem Scale (α = 0.77). For all surveyed ages, implicit self-esteem was positively biased, all ts>8.59, all ps<0.001. The simple correlation between implicit self-esteem and age was significant, r = −.25, p = 1.0×10−10. A regression with implicit self-esteem as the criterion variable, and age, gender, and age × gender interaction as predictors further revealed the significant negative linear relationship between age and implicit self-esteem, β = −0.19, t = −3.20, p = 0.001. However, explicit self-esteem manifested a reverse “U” shape throughout adolescence. Implicit self-esteem in adolescence manifests a declining trend with increasing age, suggesting that it is sensitive to developmental or age-related changes. This finding enriches our understanding of the development of implicit social cognition. PMID:24587169

Empathic accuracy: age differences from adolescence into middle adulthood.

PubMed

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.

To determine the rates of births in adolescent pregnant women in diferent regions of Thailand and assess the rates of complications occurring at pregnancy, childbirth, and postpartum in women admitted in the hospitals ofThailand. The secondary analysis of data from pregnant women aged 10 to 49 years, who were admitted to hospitals and recorded in the National Health Security Office database between October 2010 and September 2011 was carried out. Adolescent birth rate by the regions and rate of complications ofpregnancy, delivery, and postpartum by age groups were analyzed. Highest birth rate was found among women aged 19 years (58.3 per 1, 000 population). The distribution of adolescent births varied across regions of Thailand, which was high in central region. Rate of preterm delivery was highest (10%) in adolescent aged 10 to 14 years. Rate of diabetes mellitus (6%), preeclampsia (4%), and postpartum hemorrhage (3%) among women aged 35 to 49 years were substantially higher than those among women aged 34 years or less. Adolescent birth rate varied across regions of Thailand. Complications occurred differently by ages of women. Holistic policy and planning strategies for proper prevention and management among pregnant women in different age groups are needed

The relationship between sleep duration and obesity in adolescents is inconclusive. This may stem from a more complex relationship between sleep and obesity than previously considered. Shifts towards evening preferences, later sleep-wake times, and irregular sleep-wake patterns are typical during adolescence but their relationship to body mass index has been relatively unexplored. This cross sectional study examined associations between sleep duration, midpoint of sleep, and social jetlag (estimated from seven days of continuous actigraphy monitoring) and morningness/eveningness with body mass indexes (BMI z scores) and waist to height ratios in 14 to 17 year old adolescents. Seventy participants were recruited from 9th and 10th grades at a public high school. Participant characteristics were as follows: 74% female, 75% post-pubertal, 36% Hispanic, 38% White, 22% Black, 4% Asian, and 64% free/reduced lunch participants with a mean age of 15.5 (SD, 0.7). Forty one percent of the participants were obese (BMI ≥ 95th percentile); 54% were abdominally obese (waist to height ratio ≥ 0.5). Multivariable general linear models were used to estimate the association between the independent variables (school night sleep duration, free night sleep duration, midpoint of sleep (corrected), social jetlag, and morningness/eveningness) and the dependent variables (BMI z scores and waist to height ratios). Social jetlag positively associated with BMI z scores (p < 0.01) and waist to height ratios (p = 0.01). Midpoint of sleep (corrected) positively associated with waist to height ratios (p = 0.01). After adjusting for social jetlag, school night sleep duration was not associated with waist to height ratios or BMI z scores. Morningness/eveningness did not moderate the association between sleep duration and BMI z scores. Findings from this study suggest that chronobiological approaches to preventing and treating obesity may be important for accelerating progress in reducing obesity

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.

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

Mrug, Sylvie; McCay, Riley

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.

To examine risk and protective factors moderating the associations between three types of bullying victimization (physical, verbal, and relational bullying) with suicide ideation/attempts in a large representative sample of European adolescents. We analyzed cross-sectional data on 11,110 students (mean age = 14.9, standard deviation = .89) recruited from 168 schools in 10 European Union countries involved in the Saving and Empowering Young Lives in Europe study. A self-report questionnaire was used to measure victimization types, depression, anxiety, parental and peer support, and suicide ideation and attempts. For each outcome, we applied hierarchical nonlinear models controlling for sociodemographics. Prevalence of victimization was 9.4% physical, 36.1% verbal, and 33.0% relational. Boys were more likely to be physically and verbally victimized, whereas girls were more prone to relational victimization. Physical victimization was associated with suicide ideation, and relational victimization was associated with suicide attempts. Other associations between victimization and suicidality (ideation/attempts) were identified through analysis of interactions with additional risk and protective factors. Specifically, verbal victimization was associated with suicide ideation among adolescents with depression who perceived low parental support. Similarly, low peer support increased the associations between verbal victimization and suicide ideation. Verbal victimization was associated with suicide attempts among adolescents with anxiety who perceived low parental support. Findings support the development of prevention strategies for adolescent victims of bullying who may be at elevated risk for suicide ideation/behavior, by taking into account gender, the type of bullying, symptomatology, and availability of interpersonal support.

Whiteman, Shawn D; Solmeyer, Anna R; McHale, Susan M

2015-11-01

Sibling relationships have been described as love-hate relationships by virtue of their emotional intensity, but we know little about how sibling positivity and negativity operate together to affect youth adjustment. Accordingly, this study charted the course of sibling positivity and negativity from age 10 to 18 in African American sibling dyads and tested whether changes in relationship qualities were linked to changes in adolescents' internalizing and externalizing behaviors. Participants were consecutively-born siblings [at Time 1, older siblings averaged 14.03 (SD = 1.80) years of age, 48 % female; younger siblings averaged 10.39 (SD = 1.07) years of age, 52 % female] and two parents from 189 African American families. Data were collected via annual home interviews for 3 years. A series of multi-level models revealed that sibling positivity and sibling negativity declined across adolescence, with no significant differences by sibling dyad gender constellation. Controlling for age-related changes as well as time-varying parent-adolescent relationship qualities, changes in sibling negativity, but not positivity, were positively related to changes in adolescents' depressive symptoms and risky behaviors. Like parent-adolescent relationships, sibling relationships displayed some distancing across adolescence. Nevertheless, sibling negativity remained a uniquely important relational experience for African American adolescents' adjustment.

Body image, BMI, and physical activity in girls and boys aged 14-16 years.

The aim of this study was to investigate the relationship between body image, body mass index (BMI), and physical activity in adolescents. The study included 1702 girls and 1547 boys aged 14-16 years. Moderate-to-vigorous physical activity (MVPA) was evaluated by the Physical Activity Screening Measure. Body image was assessed using the Feelings and Attitudes Towards the Body Scale, and participants' BMI was determined based on measured height and weight. Compared to boys, girls reported more negative body image (p<.05). The results of the three-way hierarchical regression revealed that body image was a statistically significant positive predictor of MVPA for adolescents, regardless of BMI. Additionally, body image was a stronger predictor of MVPA in boys than in girls. These findings suggest that body image, rather than BMI, is important in undertaking physical activity in adolescents and should be considered when preparing programs aimed at improving physical activity.

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

Marijuana initiation during adolescence, and early adolescence in particular, is associated with adverse health consequences. Our study used 2005–2014 data from the annual, cross-sectional National Survey on Drug Use and Health to study the prevalence and correlates of marijuana initiation, use, and marijuana use disorder (MUD; abuse or dependence) among 12- to 14-year olds living in civilian US households (n = 84 954). Examined correlates included age, sex, race/ethnicity, poverty status, metropolitan status, year of survey, depression, tobacco use, alcohol use, and fighting at school. Sex differences in the correlates of lifetime use and past year marijuana initiation were tested via interaction. Lifetime prevalence of marijuana use was 5.5%; 3.2% reported past year initiation. About 1 in 6 (16.8%) past year initiates progressed to MUD within 12 months of first use. Although men had higher prevalence of lifetime use than women, past year initiation did not differ by sex. On examining the sex*race/ethnicity interaction effects, findings determined that non-Hispanic black and Hispanic men had higher prevalence estimates of ever using marijuana and incidence of past year initiation as compared with non-Hispanic white men; these race/ethnicity differences were not found among women. Identifying correlates of initiation and progression to MUD among young adolescents is critical to improve prevention and treatment program targets. PMID:28615948

Suicide among children and adolescents in Canada: trends and sex differences, 1980-2008.

Suicide is the second leading cause of death for young Canadians (10-19 years of age)--a disturbing trend that has shown little improvement in recent years. Our objective was to examine suicide trends among Canadian children and adolescents. We conducted a retrospective analysis of standardized suicide rates using Statistics Canada mortality data for the period spanning from 1980 to 2008. We analyzed the data by sex and by suicide method over time for two age groups: 10-14 year olds (children) and 15-19 year olds (adolescents). We quantified annual trends by calculating the average annual percent change (AAPC). We found an average annual decrease of 1.0% (95% confidence interval [CI] -1.5 to -0.4) in the suicide rate for children and adolescents, but stratification by age and sex showed significant variation. We saw an increase in suicide by suffocation among female children (AAPC = 8.1%, 95% CI 6.0 to 10.4) and adolescents (AAPC = 8.0%, 95% CI 6.2 to 9.8). In addition, we noted a decrease in suicides involving poisoning and firearms during the study period. Our results show that suicide rates in Canada are increasing among female children and adolescents and decreasing among male children and adolescents. Limiting access to lethal means has some potential to mitigate risk. However, suffocation, which has become the predominant method for committing suicide for these age groups, is not amenable to this type of primary prevention.

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.

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.

This study aimed to determine the willingness of parents to allow their sons and/or daughters aged 10-13 years to be vaccinated for human papillomavirus (HPV). This was a descriptive study conducted in an elementary school to recruit students' parents into the study. The sample consisted of 368 (69.1%) parents of children aged 10-13 years who were willing to participate in the study as a couple. Questionnaire-based data were collected from the couples. Prior information regarding HPV and vaccination and the opinions of parents of children aged 10-13 about HPV vaccination for their daughter or son. Only 26.9% of mothers and 25.0% of fathers claimed to be aware of HPV, and only 24.5% of mothers and 21.2% of fathers claimed to be aware of its vaccine. If the vaccine were available in Turkey, 21.6% of mothers and 22.4% of fathers would be willing to vaccinate their sons; although the vaccine for girls is available in Turkey, only 14.4% of mothers and 15.5% of fathers were willing to vaccinate their daughters. Few participants reported knowing about the HPV vaccine, while far fewer intended to vaccinate their daughters and sons against the infection. Both males and females should be informed about HPV and its vaccine, and initiatives to increase both awareness and the information of health care professionals should be encouraged.

Background: The National Dietary Survey on the Child and Adolescent Population in Spain (ENALIA) provides data to assess the usual micronutrient intake among Spanish infants, children, and adolescents. Methods: Cross-sectional survey (November 2012–July 2014) of a representative sample of Spanish children and adolescents (six months–17 years) (n = 1862). Dietary information was collected using two non-consecutive one-day food diaries (six months–10 years old) or two 24 h dietary recalls (11 years and older) separated by at least 14 days. Estimates were calculated using the Iowa State University method and PC-SIDE software (version 1.0, department of statistics, center for agricultural and rural development, Ames, IA, USA) to account for within- and between-person variation. Results: Usual intake of vitamin D was insufficient in practically all individuals. Vitamin E, folate, and calcium were insufficient, especially from nine years of age, and magnesium and iodine from 14 years of age. The percentage of subjects with insufficient intakes was higher among females. Sodium intake was excessive in a considerable percentage of the population, especially in males, and it increased with age. Finally, over half of children under four years of age had zinc usual intakes that exceeded the Tolerable Upper Level. Conclusion: Vitamin and mineral intake in Spain should be improved, especially in late childhood and adolescence. Nutritional intervention and educational strategies are needed to promote healthy eating habits and correct micronutrient inadequacies in Spanish children and adolescents. PMID:28208814

Girls with a combined history of low(-normal) birth weight (LBW) and precocious pubarche (PP) are at high risk to develop polycystic ovary syndrome (PCOS). The objective of the study was to compare the capacity of early vs. late metformin treatment to prevent adolescent PCOS. This was a randomized, open-label study over 7 yr. The study was conducted at a university hospital. Thirty-eight LBW-PP girls were followed up from the mean age 8 until age 15 yr. Early metformin (study yr 1-4; age 8-12 yr) vs. late metformin (yr 6; age 13-14 yr). Measures included height; weight; hirsutism score; menstrual cycle; endocrine-metabolic screening (fasting; follicular phase); C-reactive protein; body composition (absorptiometry); abdominal fat partitioning (magnetic resonance imaging); ovarian morphology (ultrasound); PCOS (National Institutes of Health and Androgen Excess Society definitions) after yr 7 (all girls thus untreated for at least 1 yr). None of the girls dropped out of the study. At age 15 yr, early-metformin girls were taller (4 cm), were in a less proinflammatory state, and had less central fat due to reductions in visceral and hepatic fat. Hirsutism, androgen excess, oligomenorrhea, and PCOS were between 2- and 8-fold more prevalent in late- than early-treated girls. Abdominal adiposity was the first variable to diverge (at age 8-10 yr) between girls without vs. with PCOS at age 15 yr. In LBW-PP girls, early metformin therapy was found to prevent or delay the development of hirsutism, androgen excess, oligomenorrhea, and PCOS more effectively than late metformin. The time window of late childhood and early puberty may be more critical for the development, and thus for the prevention, of adolescent PCOS than the first years beyond menarche.

The aim of this study was to establish reference data on third molar morphology/development for age estimation in Western Saudi adolescents, between ages 14 and 23 years of old. The orthopantomograms of 130 individuals (males and females), were examined, and the stage of third molar development were evaluated. Mean ages, standard deviations, and percentile distributions are presented for each stage of development. The mean estimated age for all participants (n = 130) was 219.7 months, and this differed significantly (P < 0.05) from the mean chronological age (226.5 months). Deviations of predicted age from real age showed 28.5% of all participants had their age estimated within 1 year (±12 months) of their chronological age. Most (43%) had their age underestimated by more than 12 months and the remaining 28.5% had their age overestimated by more than 12 months of their chronological age. Differences in left-right symmetry information of third molars were detected and were higher in the maxilla (92%) than in the mandible (82%). For all molars reaching stage "H" most individuals (males and females) were over the age 18 years of old. Males reach the developmental stages earlier than females. Third molar tooth development can be reliably used to generate mean age and the estimated age range for an individual of unknown chronological age. Further studies with large populations are needed for better statistical results.

Hypotheses about mean-level age differences in the Big Five personality domains, as well as 10 more specific facet traits within those domains, were tested in a very large cross-sectional sample (N = 1,267,218) of children, adolescents, and adults (ages 10-65) assessed over the World Wide Web. The results supported several conclusions. First, late childhood and adolescence were key periods. Across these years, age trends for some traits (a) were especially pronounced, (b) were in a direction different from the corresponding adult trends, or (c) first indicated the presence of gender differences. Second, there were some negative trends in psychosocial maturity from late childhood into adolescence, whereas adult trends were overwhelmingly in the direction of greater maturity and adjustment. Third, the related but distinguishable facet traits within each broad Big Five domain often showed distinct age trends, highlighting the importance of facet-level research for understanding life span age differences in personality.

ABSTRACT Background: The prevalence of adolescent tobacco use in Indonesia is among the highest in the world. Monitoring the extent and distribution of adolescent cigarette smoking is crucial to being able to target prevention and reduction strategies and evaluate the effectiveness of interventions. Objectives: To quantify the prevalence of adolescent cigarette smoking in Indonesia and assess the association with key socio-economic, demographic and geographic factors. Methods: We used data from the 2013 Indonesian Basic Health Research (RISKESDAS) national household survey to quantify the prevalence of cigarette smoking in adolescents aged 10–18 years by sex, age, education, economic status, place of residence and province. We used logistic regression to assess the adjusted association between adolescent smoking and these factors. Results: The overall smoking prevalence among Indonesian  adolescents was 7.2% (95% Confidence Interval/CI: 7.1–7.4). The prevalence was substantially higher among males (14.0%; 95% CI: 13.6–14.4) compared with females (0.2%; 95% CI: 0.1–0.4). After controlling for socio-economic, demographic and geographic characteristics, higher odds of smoking were observed among males (OR = 118.1; 95% CI: 91.2–153.0) as compared to female and among  adolescents aged 13–15 and 16–18 years as compared to those aged 10–12 years (OR = 13.2; 95% CI: 10.8–16.2 and OR = 72.7; 95% CI: 59.1–89.4, respectively). The odds of smoking were greater among adolescents with higher education as compared to those with lower education (OR = 1.3; 95% CI: 1.1–1.4) and adolescents in the poorest quintile had more than twice the odds of smoking compared with adolescents from the richest quintile (OR = 2.5; 95% CI: 2.2–2.8). Conclusion: Smoking prevention and cessation interventions in Indonesia need to be specific considering the sex, age, socioeconomic status and geographic location of adolescents.

To examine how adolescents' inattentive behaviour, together with parental smoking patterns, predicts smoking initiation by age 14. DESIGN, SETTINGS: A prospective, longitudinal study: baseline at ages 11-12, follow-up at age 14. A population-based sample of Finnish twins, born 1983-1987, with parents and classroom teachers as additional informants. Two groups were formed, allocating the co-twins of each family into separate groups: the study sample and a replication sample. Twin individuals (n = 4552), aged 11-12 at baseline and 14 (average 14.04 years) at follow-up. At baseline, inattentiveness was assessed with the Multidimensional Peer Nomination Inventory (MPNI, Teacher Form) and parental smoking with individual questionnaires completed by each twins' parents; at the age 14 follow-up, adolescent smoking was assessed with a self-report questionnaire. At age 14, 57% reported never having smoked, 34% had experimented with cigarettes and 9% were current smokers. Inattentiveness and parental smoking additively predicted both experimental and current smoking in adolescence. The effects were independent of each other. The risk related to inattentiveness itself is high, but in combination with the effects of parental smoking, the probability of current smoking can rise as high as 38%, compared with 5% without these two risk factors. For prevention purposes, parental commitment to non-smoking should be emphasized.

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

The aim of the study was to examine the relationships between various psychosocial factors and depressive symptoms in early adolescence. A representative sample of 2,465 12-14-year-old adolescents comprising 50.8% girls and 49.2% boys, with a mean age of 13.7 years, was recruited in two counties in Norway. The participation rate was 88.3%. Depressive symptoms were measured by the Mood and Feelings Questionnaire (MFQ). Correlations between the total sum of stressful events/daily hassles and the total sum of MFQ were moderately high, rs = .49 and rs = .53, respectively. Depressive symptoms were more strongly correlated with school-related stress among boys than girls, whereas the correlation between daily hassles and depressive symptoms was higher for girls than boys. The results of univariate analyses showed significantly higher mean total MFQ scores among adolescents not living with both natural parents, those who had moved more than twice and those with more than 3 siblings orhaving fewer than 2 close friends. Further, adolescents from Third World societies and adopted adolescents, those from lower SES groups, having unemployed parents or living in coastal areas had higher mean depressive symptom scores. The results of multiple regression analyses yielded the following six significant predictors of total MFQ scores in order of importance: Sum of daily hassles and sum of stressful life events, gender, number of friends, ethnicity and mother's employment status. Altogether, these variables accounted for 43% of the total variance in MFQ scores. It is concluded that these psychosocial predictors should be addressed when assessing depressive symptoms in early adolescence. The findings of the study are discussed in view of previous research in the field and their clinical significance.

Benchmarks and Challenges: Third Report of the Governor's Task Force on Adolescent Pregnancy.

New York State Council on Children and Families, New York.

In 1985 over 60,000 adolescents ages 10-19 became pregnant in New York State. Of these, almost 26,000 gave birth and over 33,000 terminated their pregnancies. While the majority of those who became pregnant were 18- and 19-year-olds, 1,700 were aged 10 to 14. Of the total, 59 percent were white, and 39 percent were black or from another ethnic…

The prevalence of childhood and adolescent obesity is increasing, with negative medical and psychosocial consequences. This study examines the association between weight status and nutrient intake, sport and leisure habits of middle school students in Bologna (Italy). Anthropometric data (height, weight) of 598 subjects (321 males and 277 females) 11-14 years old were collected. Questionnaires on nutrient intake, sport and leisure behaviour were administered. Protein, carbohydrate and total fat intakes of the adolescents were higher than the recommended ranges in all age groups and in both sexes. The proportion of energy from protein and total fat was higher than recommended, but the percentage from carbohydrate was lower. A significant proportion of the adolescents had a cholesterol intake above the Italian RDA and lower than recommended intakes for micronutrients. The prevalence of overweight and obesity is higher in males than in females at all ages (overweight: 35.2 vs 31.6 at 11 yrs.; 27.5 vs 20.2 at 12 yrs.; 18.6 vs 17.8 at 13 yrs.; 18.7 vs 10.9 at 14 yrs.; obesity: 5.5 vs 3.2 at 12 yrs.; 3.9 vs 1.1 at 13 yrs.; 5.3 vs 3.6 at 14 yrs.), except in subjects 11 years old (obesity: 7.4 vs 10.5). The overweight and obese adolescents consumed less carbohydrates and less fibre than their normal weight and underweight counterparts. The results of the present study indicate an unbalanced diet of the Bologna adolescents, which could damage their health and quality of life.

Understanding Adolescent Low Back Pain From a Multidimensional Perspective: Implications for Management.

Synopsis Low back pain (LBP) is the leading cause of disability worldwide. It often begins in adolescence, setting a course for later in life. We have tracked the course of LBP in the Raine Study cohort from the age of 14 years into early adulthood. Our work has found that LBP is already prevalent in individuals at 14 years of age and increases throughout adolescence and into early adulthood. It is often comorbid with other musculoskeletal pain. For some adolescents, LBP has little impact; for others, its impact includes care seeking, taking medication, taking time off from school and work, as well as modifying physical and functional activity. Of concern is the increasing prevalence of LBP with impact across adolescence, reaching adult rates by 22 years of age. The predictors of disabling LBP in adolescence are multidimensional. They include female sex, negative back pain beliefs, poor mental health status, somatic complaints, involvement in sports, and altered stress responses. Genetics also plays a role. Ironically, the factors that we have historically thought to be important predictors of LBP, such as "poor" spinal posture, scoliosis, carrying school bags, joint hypermobility, and poor back muscle endurance, are not strong predictors. This challenges our clinical beliefs and highlights that adolescent LBP needs a flexible and targeted multidimensional approach to assessment and management. In most cases, we recommend a cognitive functional approach that challenges negative LBP beliefs, educates adolescents regarding factors associated with their LBP, restores functional capacity where it is impaired, and encourages healthy lifestyle habits.

Adolescent substance use continues to be a significant public health problem. Parent training interventions are effective preventive strategies to reduce youth substance use. However, little is known about differences in effectiveness for youth across demographic characteristics. This review assessed the effectiveness of parent training programs at reducing adolescent substance use by participant gender, age, and race/ethnicity. Pubmed/MEDLINE, ERIC, CINAHL, and PsycINFO were searched from database origin to October 31, 2016. We included randomized controlled trials that evaluated parent training interventions; reported youth initiation or use of tobacco, alcohol, or other illicit substances; and included adolescents aged 10 to 19. Two independent reviewers extracted data. Disagreements were resolved by consensus or a third researcher. Data were synthesized using harvest plots stratified by participant demographics. A total of 1806 publications were identified and reviewed; 38 unique studies were included. Risk of bias of included studies was high. No studies targeted male teens or youth in late adolescence. Few studies targeted Asian-American, Black/African-American, or Hispanic/Latino adolescents. Overall, interventions including male and female youth and youth in early adolescence (age 10 to 14 or in 5th to 8th grade) were more beneficial than interventions including female-only or both young and older adolescents. Programs tailored to specific racial/ethnic groups, as well as programs designed for youth from multiple races/ethnic groups, were effective. Current evidence supports the benefits of offering parenting guidance to all families with adolescent children, regardless of the gender, age, or race/ethnicity of the adolescent.

Adolescent rats are more sensitive to the rewarding and less sensitive to the aversive properties of various drugs of abuse than their adult counterparts. Given a nationwide increase in use of "bath salts," the present experiment employed the conditioned taste aversion procedure to assess the aversive effects of 3,4-methylenedioxypyrovalerone (MDPV; 0, 1.0, 1.8, or 3.2 mg/kg), a common constituent in "bath salts," in adult and adolescent rats. As similar drugs induce thermoregulatory changes in rats, temperature was recorded following MDPV administration to assess if thermoregulatory changes were related to taste aversion conditioning. Both age groups acquired taste aversions, although these aversions were weaker and developed at a slower rate in the adolescent subjects. Adolescents increased and adults decreased body temperature following MDPV administration with no correlation to aversions. The relative insensitivity of adolescents to the aversive effects of MDPV suggests that MDPV may confer an increased risk in this population. © 2013 Wiley Periodicals, Inc.

2018-06-01

Cross-sectional studies have reported associations between liquor store availability and alcohol use among adolescents, but few prospective studies have confirmed this association. The aim of this study was to examine whether proximity to liquor stores at age 14 years was associated with alcohol intake at ages 14, 17, and 20 years. Participants of the Western Australian Pregnancy Cohort (Raine) Study (n=999) self-reported alcohol intake at age 14 years (early adolescence, 2003-2005); age 17 years (middle adolescence, 2006-2008); and age 20 years (late adolescence, 2009-2011). A GIS measured proximity to the closest liquor store from participants' home and school addresses at age 14 years. Regression analyses in 2017 assessed the relationship between distance to the closest liquor store around home, school, or both (≤800 m versus >800 m) and alcohol intake. In cross-sectional analyses (age 14 years), having a liquor store within 800 m of school was associated with ever having part of an alcoholic drink (OR=2.34, p=0.003). Also, having a liquor store within 800 m of home or school was associated with ever having part of an alcoholic drink (OR=1.49, p=0.029) and ever having engaged in heavy drinking (OR=1.79, p=0.023). In prospective analyses, liquor store proximity at age 14 years was a significant predictor of alcohol intake at age 17 years (OR=2.34, p=0.032) but not at age 20 years. Liquor store availability in early adolescence may be a risk factor for alcohol intake in early and middle, but not late, adolescence. Improved understanding of the longer-term impacts of liquor store exposure on sensitive populations could help inform future licensing regulations.

To assess whether the density of alcohol sales outlets in specific geographic communities is associated with adolescent alcohol consumption. A cross-sectional representative sample of secondary school students from Victoria, Australia (N=10,143), aged between 12 and 17 years, self-reported on alcohol use in the last 30 days in 2009. The density of alcohol outlets per local community area was merged with this information. After controlling for risk factors, multilevel modelling (MLM) revealed a statistical interaction between age and density on alcohol consumption. While older adolescents had higher alcohol consumption, increases in the density of alcohol outlets were only significantly associated with increased risk of alcohol consumption for adolescents between the ages of 12 and 14. Increased alcohol availability was associated with an increased risk of alcohol consumption specifically for early adolescents (12 and 14 years). Potential mechanisms as to how density is associated with direct and indirect alcohol availability, such as through parents or older siblings, need to be explored in future research. © 2013 Elsevier Ltd.

Rubella primary infection during early stages of pregnancy is associated with high risk of congenital Rubella syndrome (CRS). Prevention of CRS in the resource-limited countries requires multiple strategies. Here, we document the data on the magnitude of Rubella natural immunity among adolescent girls which is a crucial group in devising effective control strategies to prevent CRS. A cross sectional study involving 397 adolescent girls was conducted in the city of Mwanza involving five secondary schools. Socio-demographic and other relevant information were collected using pre-tested data collection tool. Rubella IgG antibodies were determined using enzyme immunoassay. The presence of Rubella IgG titers of >10 IU/ml indicated natural immunity. The mean age of the study participants was 15.18 ± 1.48 years. Of 397 girls, 340 (85.6%) and 57 (14.4%) were from secondary schools representing peri-urban and rural areas, respectively. Out of 397 girls, 90.4% (95% CI: 87-93) were found to be naturally immune with median Rubella IgG antibodies titers of 56.7 IU/ml interquartile range (IQR): 40.8-137. The median Rubella IgG antibodies titers were significantly high in adolescent girls from families with high socio-economic status (63.96 vs. 47.13 IU/ml, P < 0.001) and in adolescent girls from peri-urban areas of the city (63.33 vs. 39.9 IU/ml, P < 0.001). The majority of adolescent girls in the city of Mwanza are naturally immune to Rubella virus. There is a need to compare the effectiveness of screening and vaccinating susceptible adolescent girls with the effectiveness of vaccinating all women of childbearing in controlling CRS in low-income countries.

To examine the contribution of chronological age (CA), skeletal age (SA), stature, sitting stature, fat-free mass (FFM), and fat mass (FM) to interindividual variability in left ventricular mass (LVM) in male adolescent roller hockey players using allometric models. Cross sectional. Training and competitive sport during adolescence. Seventy-three Portuguese male roller hockey players aged 14.5 to 16.5 years. Stature, sitting stature, body mass, estimated FM and FFM, and SA assessed by the Fels method. Allometric modeling of LVM assessed in accordance with recommendations of the American Society of Echocardiography. Hockey players (CA: 15.4 ± 0.6 years; SA: 16.4 ± 1.5 years) showed an eccentric remodeling of LV structure within the reference range (ie, 0.24-0.42), a dilated LV chamber, but no LVM increase. Exponents for body size descriptors were 2.69 for stature (R(2) = 27%; P < 0.001), 2.49 for sitting stature (R(2) = 37%; P < 0.001), 0.76 for FFM (R(2) = 31%; P < 0.001), and 0.22 for FM (R(2) = 26%; P < 0.001). The combination of size descriptors with CA and SA increased the explained variance in LVM slightly (26%-45%). When stature and FM are used for indexing LVM in a sample of adolescent athletes, biological maturity status should also be considered.

The present study examined the role of controlled attention in age differences in event-based prospective memory performance across adolescence. The researchers tested whether presenting the prospective memory cue in or out of focal awareness of the ongoing task (resulting in low versus high demands for controlled attention, respectively) might affect age-related prospective memory performance. In total, 119 Chinese participants ages 13 to 20 took part in this study (60 adolescents: age M = 13.26 years, SD = 0.50; 23 boys; 59 young adults: age M = 19.70 years, SD = 0.87; 19 men). Findings demonstrated a significant interaction, F(1, 114) = 6.41, p < .05. No effect of age on prospective memory performance was revealed when a focal cue was used (F < 1), whereas there was a reliable age effect between adolescents and young adults when nonfocal prospective memory cues were presented, F(1, 59) = 16.13, p < .01. This pattern of results suggests that the interplay of both available resources of controlled attention and working memory, along with specific task demands, may contribute to possible age differences in prospective memory performance across adolescence. Results are discussed in the context of the multiprocess theory of prospective memory.

A variety of performance outputs are strongly determined by lower limbs volume and composition in children and adolescents. The current study aimed to examine the validity of thigh volume (TV) estimated by anthropometry in late adolescent female volleyball players. Dual-energy X-ray absorptiometry (DXA) measures were used as the reference method. Total and regional body composition was assessed with a Lunar DPX NT/Pro/MD+/Duo/Bravo scanner in a cross-sectional sample of 42 Portuguese female volleyball players aged 14-18 years (165.2 ± 0.9 cm; 61.1 ± 1.4 kg). TV was estimated with the reference method (TV-DXA) and with the anthropometric method (TV-ANTH). Agreement between procedures was assessed with Deming regression. The analysis also considered a calibration of the anthropometric approach. The equation that best predicted TV-DXA was: -0.899 + 0.876 × log 10 (body mass) + 0.113 × log 10 (TV-ANTH). This new model (NM) was validated using the predicted residual sum of squares (PRESS) method (R 2 PRESS  = 0.838). Correlation between the reference method and the NM was 0.934 (95%CI: 0.880-0.964, S y∙x  = 0.325 L). A new and accurate anthropometric method to estimate TV in adolescent female volleyball players was obtained from the equation of Jones and Pearson alongside with adjustments for body mass.

BACKGROUND Acne is a common disease in adolescents, but there are no epidemiological data for acne in Brazil. OBJECTIVES To estimate the prevalence and degree of acne in adolescents from Sao Paulo and study socio-demographic factors, family history and lifestyle, associated with the disease. METHODS Cross-sectional study with 452 adolescents aged between 10 and 17 (mean=13.3 years), students from elementary and high school, examined by 3 independent evaluators. RESULTS 62.4% were female, 85.8% white and 6.4% were aged 14. The prevalence was 96.0% and increased with age - all students over 14 had acne. The most prevalent form of acne was comedonal (61.1%), followed by mild (30.6%) and moderate (7.6%) papular-pustular, which affected mostly the face (97.5%). About half of the adolescents reported family history for acne in mother or father, and 20.6% reported previous treatment for acne. There was a higher chance of presenting non-comedonal acne with increased age (p<0.001). DISCUSSION The prevalence of acne in adolescents varies widely due to the clinical features and diagnostic methods used. Adolescents whose brothers/sisters had acne (OR=1.7-p=0.027) and those over 13 (OR=8.3-p<0.001), were more likely to have non-comedonal acne. CONCLUSION This study showed high prevalence of acne in adolescents from Sao Paulo, predominantly the comedonal form on the face, with a higher chance of presenting non-comedonal acne with increased age.

Objectives The aims of the present study were to assess the prevalence of bullying victimization among Korean adolescents by sex and age and to investigate the correlates of this phenomenon. Methods Of 3,200 eligible subjects, 2,936 (91.8%) adolescents were recruited from four elementary schools (6th grade, age range: 10–12 years), five middle schools (8th grade, age range: 13–14 years), and three high schools (10th grade, age range: 15–17 years) located in the Jeju Special Self-Governing Province, Republic of Korea. This study used a self-administered questionnaire to collect data on sociodemographic characteristics and experiences of bullying victimization and employed the Korean form of the Children’s Depression Inventory to evaluate depressive symptoms. Results Of the total sample of 2,936 students, 1,689 were boys (57.5%) and 1,247 were girls (42.5%). The prevalence of bullying victimization by age group was as follows: 10–12 years, 9.5%; 13–14 years, 8.3%; and 15–17 years, 6.4%. A significant difference in the prevalence of bullying victimization was observed by sex (boys: 45.0%, girls: 55.0%). Overall, the prevalence decreased with age. After adjusting for age and sex, bullying victimization was significantly associated with lower socioeconomic status (odds ratio [OR] =1.67; 95% confidence interval [CI] 1.04–2.67), lower than average academic achievement (OR =1.77; 95% CI 1.25–2.50), more depressive symptoms (OR =1.88; 95% CI 1.38–2.55), and poorer perceived relationship with parents (OR =1.46; 95% CI 1.00–2.14). Conclusion Our findings will provide researchers and public health practitioners with data on the prevalence of bullying victimization and help to identify the risk factors for later behavioral and emotional problems.

2008-08-01

While parental supervision has been demonstrated to predict adolescent alcohol involvement, there has been little focus on the influence of adolescent characteristics, such as personality and alcohol use, on the effectiveness of parental supervisory practices. This study examined the interaction of parental supervision and adolescent alcohol use from late childhood through middle adolescence. Families were recruited through fathers with substance use disorders or fathers representing reference groups identified as having a biological child age 10 to 12 years. These children (N = 773) were assessed and follow-up visits conducted in early adolescence (ages 12-14) and middle adolescence (age 16). Parental supervision and alcohol use were determined at each visit. In the context of demographic variables and childhood psychological dysregulation, the statistical model examined global and developmental stage-specific relationships between supervision and alcohol use. Consistent with interactional hypotheses, childhood psychological dysregulation and early adolescent alcohol use predicted less effective parental supervision. While the study design limited the extent to which predictive associations could be interpreted as indicating causal relationships, adolescents with psychological dysregulation and higher levels of alcohol use may resist parental supervision. The challenges to parents presented by difficult adolescents need to be taken into consideration in developing preventive and treatment interventions.

A study on behavioral and emotional problems and competence in children and adolescents in Germany (PAK-KID study) is described. It is the first nationwide representative survey of this kind of children and adolescents aged 4 to 18 years in Germany. For children aged 4 to 10 years the parents completed the German version of Achenbach's Child Behavior Checklist (CBCL 4-18) developed by the Arbeitsgruppe Deutsche Child Behavior Checklist. Children and adolescents aged 11 years and older filled out the German version of the Youth Self-Report that is part of Achenbach's CBCL in addition to the parents completing the German version of the CBCL. A total of 2856 parent questionnaires and 1798 self-report questionnaires completed by children and adolescents were analyzed. The sample was representative with respect to the main sociodemographic variables. On all problem scales children and adolescents aged 11 to 18 years reported significantly more problems than their parents did. The frequency of internalizing problems (social withdrawal, somatic complaints, anxiety/depression) and delinquent behavior of children and adolescents reported by parents increased with the children's age, whereas aggressive behavior and attention problems decreased with age. Girls reported significantly more problems than boys on all internalizing scales of the Youth Self-Report. The effect was not totally replicated in the parent reports. In the parent reports, boys had more attention problems and more aggressive and delinquent behavior than girls.

Motocross racing is a popular sport; however, its impact on the growing/developing pediatric spine is unknown. Using a retrospective cohort model, the authors compared the degree of advanced degenerative findings in young motocross racers with findings in age-matched controls. Patients who had been treated for motocross-related injury at the authors' institution between 2000 and 2007 and had been under 18 years of age at the time of injury and had undergone plain radiographic or CT examination of any spinal region were eligible for inclusion. Imaging was reviewed in a blinded fashion by 3 physicians for degenerative findings, including endplate abnormalities, loss of vertebral body height, wedging, and malalignment. Acute pathological segments were excluded. Spine radiographs from age-matched controls were similarly reviewed and the findings were compared. The motocross cohort consisted of 29 riders (mean age 14.7 years; 82% male); the control cohort consisted of 45 adolescents (mean age 14.3 years; 71% male). In the cervical spine, the motocross cohort had 55 abnormalities in 203 segments (average 1.90 abnormalities/patient) compared with 20 abnormalities in 213 segments in the controls (average 0.65/patient) (p = 0.006, Student t-test). In the thoracic spine, the motocross riders had 51 abnormalities in 292 segments (average 2.04 abnormalities/patient) compared with 25 abnormalities in 299 segments in the controls (average 1.00/patient) (p = 0.045). In the lumbar spine, the motocross cohort had 11 abnormalities in 123 segments (average 0.44 abnormalities/patient) compared with 15 abnormalities in 150 segments in the controls (average 0.50/patient) (p = 0.197). Increased degenerative changes in the cervical and thoracic spine were identified in adolescent motocross racers compared with age-matched controls. The long-term consequences of these changes are unknown; however, athletes and parents should be counseled accordingly about participation in motocross

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.

Although national poison center data show that pesticides were the 8th most commonly reported substance category (3.27%) for children aged ≤5 years in 2014, there is limited information on childhood and adolescent pesticide exposures. This study assessed pesticide-related poison center exposures in children and adolescents aged ≤19 years from 2000-2013 in Texas to characterize the potential burden of pesticides. Pesticide-related poison center exposures among children and adolescents aged ≤19 years reported to Texas poison centers were identified. The distribution of exposures was estimated by gender, age category, medical outcome, management site, exposure route, and pesticide category. From 2000 to 2013, there were 61,147 pesticide-related poison center exposures in children and adolescents aged ≤19 years. The prevalence was highest among males at 864.24 per 100,000 population. The prevalence of unintentional exposures was highest among children aged ≤5 years at 2310.69 per 100,000 population, whereas the prevalence of intentional exposures was highest among adolescents aged 13-19 years at 13.82 per 100,000 population. A majority of medical outcomes reported were classified as having no effect (30.24%) and not followed, but minimal clinical effects possible (42.74%). Of all the exposures, 81.24% were managed on site. However, 57% of intentional exposures were referred to or treated at a health-care facility. The most common routes of exposure were ingestion (80.83%) and dermal (17.21%). The most common pesticide categories included rodenticides (30.02%), pyrethrins/pyrethroids (20.69%), and other and unspecified insecticides (18.14%). The study found differences in the frequency of exposures by intent for sex and age categories, and identified the most common medical outcomes, management site, exposure route, and pesticide category. Through characterizing pesticide-related poison center exposures, future interventions can be designed to address groups

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.

Little is known about the influence of different types and sources of social support on physical activity in adolescents. The aim of this study was to analyse the association between physical activity and different types and sources of social support in adolescents. The sample consisted of 2,859 adolescents between 14-19 years of age in the city of João Pessoa, in Northeastern Brazil. Physical activity was measured with a questionnaire and social support from parents and friends using a 10-item scale five for each group (type of support: encouragement, joint participation, watching, inviting, positive comments and transportation). Multivariable analysis showed that the types of support provided by parents associated with physical activity in adolescents were encouragement for females (P < 0.001) and adolescents between 14-16 years of age (P = 0.003), and transportation (P = 0.014) and comments (P = 0.037) for males. The types of social support provided by friends were: joint participation in male adolescents (P < 0.001) and in these 17-19-year-olds (P < 0.001), and comments in both genders (males: P = 0.009; females: P < 0.001) and 14-16-year-olds (P < 0.001). We conclude that the type of social support associated with physical activity varies according to its source, as well as the gender and age of the adolescents.

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.

To study the current situation of ten types of junk food consumption (assessed by World Health Organization) among children and adolescent as well as the contributing factors in Haidian District, Beijing so as to provide evidence for developing preventive and control measures and interventions. A questionnaire survey was conducted to investigate the consumption of ten types of junk food practices in 1019 children and adolescent aged 8-16 years in Beijing Haidian District. One month prior to the study, 97.50% of the children and adolescent had eaten at least one type of junk food and 15.88% of them had eaten all types of them. Rates on having eaten deep fried food, pickled food, processed meat products, biscuits, coke or alike drinks, convenience/fast food, canned food, dried or preserved fruit, cold and sweet food, barbecue food etc. appeared to be 70.43%, 60.14%, 79.72%, 64.24%, 69.63%, 78.72%, 42.16%, 51.95%, 68.13%, 60.14% respectively. The rate on eaten more than once a day of these ten types were 26.95%, 36.88%, 34.84%, 32.97%, 27.40%, 28.18%, 37.91%, 26.15%, 37.39%, 22.10% respectively. The rates for "do not like" and "dislike" these ten types junk food were 10.96%, 27.42%, 7.08%, 12.11%, 6.56%, 6.59%, 17.80%, 13.59%, 3.42%, 5.19% respectively. Most of the children and adolescent ate junk food mainly during breakfast at home. Most of the surveyed children and adolescent did not have correct idea on nutrition of junk food. They received the information of junk food mainly from sources as advertisement on TV (67.95%), mother (9.02%), newspaper or magazines (6.71%). Many factors, such as individual factors (including physiological and psychological situations), social factors, family factors and the characteristics of food contributed to the eating junk food practices of children and adolescent. Eating junk food is a popular event among children and adolescent in Beijing Haidian District. Education strategies on nutrition should be developed and launched in

Catatonia has been associated with both schizophrenia and pervasive developmental disorders. The aim of this study was to evaluate catatonic features among adolescents suffering from schizophrenia. Further, we compared these features between adolescents with a comorbid pervasive developmental disorder and those without one. Finally, we wanted to compare the profile of catatonia-like features of our schizophrenia patients to that described earlier among persons with autism spectrum disorders. The study comprised a consecutive sample of 18 adolescents with schizophrenia (mean age 15.6 years, SD 1.4) and their families. Diagnosis of schizophrenia was assessed with the Schedule for Affective Disorders and Schizophrenia for School-Aged Children - Present and Life-Time (K-SADS-PL) for the DSM-IV. The Diagnostic Interview for Social and Communication Disorders version 11 was used to assess catatonic features. All adolescents with schizophrenia had showed some lifetime catatonic features. Approximately 78% of them had already expressed these features before the age of 10. The number of catatonic features before the age of 10 was significantly higher among the adolescents with a comorbid pervasive developmental disorder compared to those without one. The numbers of catatonic features after the age of 10 did not significantly differ between the two groups. Over three-quarters of schizophrenia patients shared four lifetime catatonic features: "lacks facial expression", "odd intonation", "poor eye contact" and "lack of cooperation". Adolescent schizophrenia patients with a comorbid pervasive developmental disorder show many catatonic features in childhood whereas those without one seem to develop these features first in adolescence. Catatonic features exhibited by adolescents with schizophrenia resemble those described among persons with pervasive developmental disorders without schizophrenia.

Fractures of the clavicle are common among adolescents and have traditionally been treated nonoperatively. Recent literature has demonstrated less satisfactory results than expected after conservative management of displaced fractures in adults. The purpose of this study was to evaluate the long-term patient-reported outcome after clavicle fractures in older children and adolescents. Children aged 10 to 18 years who sustained a fracture of the clavicle between 2006 and 2008 were identified in our institution's computerized files. The radiographs were examined and the fracture patterns, degree of dislocation, and shortening were measured. Medical records were reviewed and the patient-reported outcome was assessed using the Oxford Shoulder score and the Quick version of the Disability of Arm, Shoulder, and Hand questionnaire, and specific and general satisfaction scores. A total of 185 patients (median age, 14.4 y) with 172 midshaft and 13 lateral fractures were included in the study. Sixty-five (37.8%) of the midshaft fractures were displaced, and 9 of these were operated. There was one case of nonunion and one delayed union. One hundred twenty-two (70.9%) of the patients with a midshaft fracture responded to the questionnaires on an average 4.7 years after injury. Overall results were good to excellent for the majority of nonoperatively treated patients; however, shortening of the fracture had a negative effect on the Oxford Shoulder score (P=0.02), the cosmetic satisfaction score (P=0.02), and the overall satisfaction score (P=0.01). The long-term patient-reported outcome after nonoperatively treated fractures of the clavicle in adolescents is good to excellent for the majority of the patients, and nonunion is rare. However, shortening of the fracture had a small negative effect on the outcome. Conservative management should remain the mainstay of management for fractures of the clavicle in this age group. Level IV-retrospective case series.

Neurodevelopmental differences to social exclusion: An event-related neural oscillation study of children, adolescents, and adults.

Although the neural correlates of social exclusion have been well-documented, most studies have examined single age groups. No studies have directly compared specific age-related differences in social exclusion across children, adolescents, and adults using event-related oscillatory electroencephalogram (EEG) dynamics. The authors examined event-related theta EEG power and phase coherence in fair play and social exclusion conditions during the Cyberball task in 166 participants: 42 children (ages 10-12), 56 adolescents (ages 14-17), and 68 adults (ages 18-28). Children and adolescents displayed the greatest theta power to rejection events, whereas adults displayed the greatest theta power to "not my turn" events. Moreover, the functional link between theta power to rejection and self-reported distress was strongest among the adolescents. These findings suggest that an enhanced neural response to social exclusion is present by preadolescence, but the association between neural and subjective responses is most prominent during adolescence.

Online communication tools, such as social networking sites (SNS), have been comprehensively embraced by adolescents and have become a dominant daily social practice. Recognizing SNS as a key context of adolescent development, this study aimed to investigate associations between heavier SNS use, and adolescent competencies and internalizing problems. Data was collected in six European countries: Greece, Spain, Poland, the Netherlands, Romania, and Iceland. Participants were 10,930 adolescents aged 14-17 years (F/M: 5,719/5,211; mean age 15.8 ± .7 years); 62.3% were aged 14-15.9 years and 37.7% were aged 16-17.9 years. Participants reported on their use of online communication tools, and their general competencies and internalizing problems (Youth Self Report). SNS are both ubiquitous--used by 70% of adolescents--and engaging, given that 40% of users spend 2 or more hours daily on SNS (labeled heavier SNS use). Heavier SNS use was associated with more internalizing problems, and the relation was consistently more pronounced among younger adolescents. Moreover, heavier SNS use was associated with lower academic performance and lower activities scores, especially for younger adolescents. In contrast, among older adolescents heavier SNS use was positively associated with offline social competence. Although heavier SNS use is associated with higher social competence for older adolescents, it is also associated with increased internalizing problems and diminished competencies in academics and activities, especially for younger adolescents. Age, capturing developmental differences in social and regulatory skills, appears to moderate the effects of heavier SNS use on adolescent functioning.

Objective: To investigate the prevalence of metabolic syndrome (MS) among children and adolescents aged 10-16 years old in 7 provinces in China. Methods: Using the method of stratified cluster random sampling, 93 primary and secondary schools were selected from Guangdong, Hunan, Liaoning, Shanghai, Chongqing, Tianjin, and Ningxia provinces in China. A total of 9 296 students aged 10-16 years old with complete physical and biochemical parameters were selected as the subjects of the present study from above 93 primary and secondary schools. MS was determined using the definition of 'guideline of 2010 Chinese children and adolescents MS definition and treatment'. The standardized age-sex composition of the 2010 census was used to standardize the MS detection rate of every province. Chi-square test was used to compare the difference of MS prevalence among participants with different characteristics. Results: The prevalence of MS was 4.1% (384/9 296) among children and adolescents aged 10-16 years old in 7 provinces in China. The prevalence of MS among males was 5.0% (237/4 754), which was significantly higher than females (3.2%) (147/4 542) ( P< 0.05). Stratified by nutrition conditions, the prevalence of MS was 0, 0.6% (39/6 733), 8.9% (104/1 170), 30.0% (241/803) for thin, normal weight, overweight, and obese population, respectively. The MS prevalence increased with the increase of body mass index (BMI) ( P< 0.001). Stratified by provinces, the prevalence of MS was the highest in Tianjin (9.2%) and the lowest in Hunan province (0.8%). Conclusion: The prevalence of MS was high among children and adolescents aged 10-16 years old in 7 provinces in China. MS prevalence among males was higher than females; MS prevalence among overweight/obese population was higher than normal weight population. The detection rate of metabolic syndrome was different in different provinces.

Concussion injuries have been highlighted to the American public through media and research. While recent studies have shown increased traumatic brain injuries (TBIs) diagnosed in emergency departments across the United States, no studies have evaluated trends in concussion diagnoses across the general US population in various age groups. To evaluate the current incidence and trends in concussions diagnosed across varying age groups and health care settings in a large cross-sectional population. Descriptive epidemiological study. Administrative health records of 8,828,248 members of a large private-payer insurance group in the United States were queried. Patients diagnosed with concussion from years 2007 through 2014 were stratified by year of diagnosis, age group, sex, classification of concussion, and health care setting of diagnosis (eg, emergency department vs physician's office). Chi-square testing was used for statistical analysis. From a cohort of 8,828,248 patients, 43,884 patients were diagnosed with a concussion. Of these patients, 55% were male and over 32% were in the adolescent age group (10-19 years old). The highest incidence of concussion was seen in patients aged 15 to 19 years (16.5/1000 patients), followed by those aged 10 to 14 years (10.5/1000 patients), 20 to 24 years (5.2/1000 patients), and 5 to 9 years (3.5/1000 patients). Overall, there was a 60% increase in concussion incidence from 2007 to 2014. The largest increases were in the 10- to 14-year (143%) and 15- to 19-year (87%) age groups. Based on International Classification of Disease-9th Revision classification, 29% of concussions were associated with some form of loss of consciousness. Finally, 56% of concussions were diagnosed in the emergency department and 29% in a physician's office, with the remainder in urgent care clinics or inpatient settings. The incidence of concussion diagnosed in the general US population is increasing, driven largely by a substantial rise in the adolescent

Pattern of injury mortality by age-group in children aged 0-14 years in Scotland, 2002-2006, and its implications for prevention.

Knowledge of the epidemiology of injuries in children is essential for the planning, implementation and evaluation of preventive measures but recent epidemiological information on injuries in children both in general and by age-group in Scotland is scarce. This study examines the recent pattern of childhood mortality from injury by age-group in Scotland and considers its implications for prevention. Routine mortality data for the period 2002-2006 were obtained from the General Register Office for Scotland and were analysed in terms of number of deaths, mean annual mortality rates per 100,000 population, leading causes of death, and causes of injury death. Mid-year population estimates were used as the denominator. Chi-square tests were used to determine statistical significance. 186 children aged 0-14 died from an injury in Scotland during 2002-06 (MR 4.3 per 100,000). Injuries were the leading cause of death in 1-14, 5-9 and 10-14 year-olds (causing 25%, 29% and 32% of all deaths respectively). The leading individual causes of injury death (0-14 years) were pedestrian and non-pedestrian road-traffic injuries and assault/homicide but there was variation by age-group. Assault/homicide, fire and suffocation caused most injury deaths in young children; road-traffic injuries in older ones. Collectively, intentional injuries were a bigger threat to the lives of under-15s than any single cause of unintentional injury. The mortality rate from assault/homicide was highest in infants (<1 year) and decreased with increasing age. Children aged 5-9 were significantly less likely to die from an injury than 0-4 or 10-14 year-olds (p < 0.05). Suicide was an important cause of injury mortality in 10-14 year-olds. Injuries continue to be a leading cause of death in childhood in Scotland. Variation in causes of injury death by age-group is important when targeting preventive efforts. In particular, the threats of assault/homicide in infants, fire in 1-4 year-olds, pedestrian injury

Sexual initiation, contraceptive use, and pregnancy among young adolescents.

To present new data on sexual initiation, contraceptive use, and pregnancy among US adolescents aged 10 to 19, and to compare the youngest adolescents' behaviors with those of older adolescents. Using nationally representative data from several rounds of the National Survey of Family Growth, we performed event history (ie, survival) analyses to examine timing of sexual initiation and contraceptive use. We calculated adolescent pregnancy rates by single year of age using data from the National Center for Health Statistics, the Guttmacher Institute, and the US Census Bureau. Sexual activity is and has long been rare among those 12 and younger; most is nonconsensual. By contrast, most older teens (aged 17-19) are sexually active. Approximately 30% of those aged 15 to 16 have had sex. Pregnancy rates among the youngest teens are exceedingly low, for example, ∼1 per 10 000 girls aged 12. Contraceptive uptake among girls as young as 15 is similar to that of their older counterparts, whereas girls who start having sex at 14 or younger are less likely to have used a method at first sex and take longer to begin using contraception. Sexual activity and pregnancy are rare among the youngest adolescents, whose behavior represents a different public health concern than the broader issue of pregnancies to older teens. Health professionals can improve outcomes for teenagers by recognizing the higher likelihood of nonconsensual sex among younger teens and by teaching and making contraceptive methods available to teen patients before they become sexually active.

Objective To examine the associations between age and genital injuries in adolescent and young adult women examined following rape. Design & Setting A retrospective review of 234 medical records from an emergency department sexual assault program. Sample Women aged 14 to 29 years. Fifty percent of the sample was African American, 48% was White, and 2% was either Asian or an “other” race. Main Outcome Measures Genital injury was described by injury prevalence, frequency, and anatomical locations of injuries. Results Overall genital injury prevalence was 62.8%. Younger age was not significantly associated with the presence or absence of genital injury. However, younger age was significantly associated with an increased number of genital injuries overall and to the thighs, labia minora, periurethral area, fossa navicularis, and vagina. Conclusion These findings support the need for further research to determine if the current care provided to rape survivors is age appropriate. PMID:18507599

Direct-to-adolescent text messaging may be a consideration for vaccine reminders, including human papilloma virus (HPV), but no studies have explored the minimum age at which parents would allow adolescents to receive a text message. We distributed a survey to parents of 10-17 year olds during any office visit in two practice based research networks in South Carolina and Oklahoma. We asked about parental preference for receiving vaccine reminders for their adolescent, whether they would allow the healthcare provider to directly message their adolescent, and if so, what would be the acceptable minimum age. In 546 surveys from 11 practices, parents of females were more supportive of direct-to-teen text message reminders than were parents of males, (75% v. 60%, p < .001). The median age at which parents would allow direct text messages from physicians' offices was 14 in females compared to 15 in males, p = .049. We found a correlation between the child's age and the youngest age at which parents would allow a direct text message. Of the parents who permitted a text message directly to their adolescent, most reported an allowable age higher than their adolescent's current age until the age of 15. Our study suggests that direct-to-adolescent text messaging would be allowed by parents for older adolescents.

Ferritin reference values vary by age, gender, and ethnicity. We aimed to determine reference values of serum ferritin (SF) and the percentage of transferrin saturation (TSAT) for Korean children and adolescents. We analyzed data from 2,487 participants (1,311 males and 1,176 females) aged 10-20 years from the Korea National Health and Nutrition Examination Survey (2010-2012). We calculated age- and gender-stratified means and percentile values for SF and TSAT. We first plotted mean SF and TSAT by gender and according to age. In males, mean SF tended to be relatively constant among participants aged 10 to 14 years, with an upward trend thereafter. Mean SF trended downward among female participants until the age of 15 years and remained constant thereafter. Thus, significant gender differences in ferritin exist from the age of 14 years. High levels of SF were associated with obesity, and lower SF levels were associated with anemia and menarche status. We established reference values of SF and TSAT according to age and gender. The reference values for SF calculated in this study can be used to test the association between SF values and other defined diseases in Korean children and adolescents.

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.

Transition into adulthood is a critical developmental period that may be influenced by adverse life events as well as by protective factors. This study aimed at investigating the effect of different forms of child maltreatment experienced prior to age 14 (i.e., sexual abuse, physical abuse and exposure to intimate partner violence), and of friend support at age 14 on the psychological distress trajectory from age 14 to 24. Participants were 605 adolescents from the general population involved in a 10-year longitudinal study. Psychological distress was evaluated at ages 14, 16, 18 and 24. Child maltreatment prior to 14 years was retrospectively assessed at 14 and 24 years while perception of support from friends was evaluated at age 14. Multilevel growth modeling indicated that psychological distress followed a significant decreasing curvilinear trajectory, with participants reporting fewer distressing psychological symptoms after 18 years. All three forms of child maltreatment, as well as their cumulative effect, predicted more psychological distress over 10 years above and beyond the protective effect of support from friends. Higher support from friends at age 14 was related to lower distress at baseline andover 10 years, beyond the effect of child maltreatment. Self-report nature of all measures, attrition, and measures of child maltreatment forms. Psychological distress decreased during the transition from adolescence to emerging adulthood. Results also revealed the detrimental impact of child maltreatment and the promotive role of friend support, which underscore the importance of early intervention. Copyright © 2015 Elsevier B.V.

Processing of reward is the basis of adaptive behavior of the human being. Neural correlates of reward processing seem to be influenced by developmental changes from adolescence to late adulthood. The aim of this study is to uncover these neural correlates during a slot machine gambling task across the lifespan. Therefore, we used functional magnetic resonance imaging to investigate 102 volunteers in three different age groups: 34 adolescents, 34 younger adults, and 34 older adults. We focused on the core reward areas ventral striatum (VS) and ventromedial prefrontal cortex (VMPFC), the valence processing associated areas, anterior cingulate cortex (ACC) and insula, as well as information integration associated areas, dorsolateral prefrontal cortex (DLPFC), and inferior parietal lobule (IPL). Results showed that VS and VMPFC were characterized by a hyperactivation in adolescents compared with younger adults. Furthermore, the ACC and insula were characterized by a U-shape pattern (hypoactivation in younger adults compared with adolescents and older adults), whereas the DLPFC and IPL were characterized by a J-shaped form (hyperactivation in older adults compared with younger groups). Furthermore, a functional connectivity analysis revealed an elevated negative functional coupling between the inhibition-related area rIFG and VS in younger adults compared with adolescents. Results indicate that lifespan-related changes during reward anticipation are characterized by different trajectories in different reward network modules and support the hypothesis of an imbalance in maturation of striatal and prefrontal cortex in adolescents. Furthermore, these results suggest compensatory age-specific effects in fronto-parietal regions. Copyright © 2014 Wiley Periodicals, Inc.

To estimate seroprevalence of Bordetella pertussis in students and their community. A total of 12,273 adolescent students aged 12 to 15 years from 14 public high schools in Mexico City were studied from September 2002 to March 2003. Nasopharyngeal samples were collected from those adolescents with whooping cough for more than 14 days. Infection was confirmed using polymerase chain reaction (PCR). All students, school staff and family exposed to PCR-confirmed cases were tested. Whooping cough rate was 5 to 1,000 students. Of those students (61) who were identified with whooping cough for more than 14 days, 20 (32.8%) were positive to Bordetella pertussis. Of 152 people exposed (contacts) to these cases, 16 (10.6%) were positive and only eight (50%) had whooping cough. One of these exposed (contacts) was the principal of a school that had more than 60% positive cases (12/20) and who was also a teacher of 10 infected students. Of 29 family members tested, eight (27.6%) were positive and from three different families. The study results show a similar rate of whooping cough in adolescents as seen in other countries. Since persistent cough is not always clinically seen in all infected individuals, there may be asymptomatic cases of Bordetella infection.

Young athletes experience numerous dietary challenges including growth, training/competition, unhealthy food environments, and travel. The objective was to determine nutrient intakes and supplement use in pre-adolescent and adolescent Canadian athletes. Athletes (n = 187) aged 11–18 years completed an on-line 24-h food recall and dietary supplement questionnaire. Median energy intake (interquartile range) varied from 2159 kcal/day (1717–2437) in 11–13 years old females to 2905 kcal/day (2291–3483) in 14–18 years old males. Carbohydrate and protein intakes were 8.1 (6.1–10.5); 2.4 (1.6–3.4) in males 11–13 years, 5.7 (4.5–7.9); 2.0 (1.4–2.6) in females 11–13 years, 5.3 (4.3–7.4); 2.0 (1.5–2.4) in males 14–18 y and 4.9 (4.4–6.2); 1.7 (1.3–2.0) in females 14–18 years g/kg of body weight respectively. Median vitamin D intakes were below the recommended dietary allowance (RDA) and potassium was below the adequate intake (AI) for all athlete groups. Females 14–18 years had intakes below the RDA for iron 91% (72–112), folate 89% (61–114) and calcium 84% (48–106). Multivitamin-multiminerals, vitamin C, vitamin D, vitamin-enriched water, protein powder, sport foods, fatty acids, probiotics, and plant extracts were popular supplements. Canadian pre-adolescent and adolescent athletes could improve their dietary intakes by focusing on food sources of calcium, vitamin D, potassium, iron, and folate. With the exceptions of vitamin D and carbohydrates during long exercise sessions, supplementation is generally unnecessary. PMID:27571101

2011-01-01

Little empirical evidence exists regarding the developmental links between childhood psychopathology and borderline personality disorder (BPD) in adolescence. The current study addresses this gap by examining symptoms of attention deficit hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) as potential precursors. ADHD and BPD share clinical features of impulsivity, poor self-regulation, and executive dysfunction, while ODD and BPD share features of anger and interpersonal turmoil. The study is based on annual, longitudinal data from the two oldest cohorts in the Pittsburgh Girls Study (N = 1233). We used piecewise latent growth curve models of ADHD and ODD scores from age 8–10 and 10–13 years to examine the prospective associations between dual trajectories of ADHD and ODD symptom severity and later BPD symptoms at age 14 in girls. To examine the specificity of these associations, we also included conduct disorder (CD) and depression symptom severity at age 14 as additional outcomes. We found that higher levels of ADHD and ODD scores at age 8 uniquely predicted BPD symptoms at age 14. Additionally, the rate of growth in ADHD scores from age 10–13 and the rate of growth in ODD scores from 8–10 uniquely predicted higher BPD symptoms at age 14. This study adds to the literature on the early development of BPD by providing the first longitudinal study to examine ADHD and ODD symptom trajectories as specific childhood precursors of BPD symptoms in adolescent girls.

Polycystic ovary syndrome (PCOS) is linked with metabolic syndrome, which includes obesity, insulin resistance, dyslipidemia, and endocrine function in patients with PCOS. The aim of this study was to determine the prevalence of adolescent PCOS and characteristics associated with PCOS in adolescents in Babol, Iran. A cross-sectional study was conducted on 1549 girl high school students aged 16-20 years who were living in Iran. After overnight fasting, blood samples were collected to determine hormones and lipid levels in PCOS patients between the first and fifth days of their menstrual period or withdrawal bleeding. The overall prevalence of adolescent PCOS was 129 (8.3%) (95% CI; 4.0, 12.0). Irregular menstruation was observed in 24.1% of adolescents. A total of 68% of PCOS adolescents had insulin resistance. Compared with non-PCOS adolescents, the OR of adolescent PCOS for family history of hirsutism was 1.53 (95% CI, 1.06-2.20; p=0.024), family history of irregular menstrual cycle was 2.27 (95% CI, 1.56-3.30; p<0.001), menarche age <13 years was 1.95 (95% CI, 1.36-2.81; p<0.001), hirsutism was 1.14 (CI 95%, 1.10-1.17; p<0.001), acne was 5.10 (CI 95%, 3.52-7.40; p<0.001), and wrist circumference was 1.28 (CI 95%, 1.07-1.54; p=0.007). The presenting findings showed the high prevalence of PCOS among Iranian adolescents. Emphasis should be placed on clinical screening in adolescents with high-risk factors, including irregular menstrual, menarche <13 years, hirsutism, acne, high wrist circumference, and paternal obesity to help reduce the risk of developing metabolic disturbance and to find ways to improve long-term health.

Temporal and probabilistic discounting of rewards in children and adolescents: effects of age and ADHD symptoms.

2006-01-01

This study investigated whether age and ADHD symptoms affected choice preferences in children and adolescents when they chose between (1) small immediate rewards and larger delayed rewards and (2) small certain rewards and larger probabilistic uncertain rewards. A temporal discounting (TD) task and a probabilistic discounting (PD) task were used to measure the degree to which the subjective value of a large reward decreased as one had to wait longer for it (TD), and as the probability of obtaining it decreased (PD). Rewards used were small amounts of money. In the TD task, the large reward (10 cents) was delayed by between 0 and 30s, and the immediate reward varied in magnitude (0-10 cents). In the PD task, receipt of the large reward (10 cents) varied in likelihood, with probabilities of 0, 0.25, 0.5, 0.75, and 1.0 used, and the certain reward varied in magnitude (0-10 cents). Age and diagnostic group did not affect the degree of PD of rewards: All participants made choices so that total gains were maximized. As predicted, young children, aged 6-11 years (n = 25) demonstrated steeper TD of rewards than adolescents, aged 12-17 years (n = 21). This effect remained significant even when choosing the immediate reward did not shorten overall task duration. This, together with the lack of interaction between TD task version and age, suggests that steeper discounting in young children is driven by reward immediacy and not by delay aversion. Contrary to our predictions, participants with ADHD (n = 22) did not demonstrate steeper TD of rewards than controls (n = 24). These results raise the possibility that strong preferences for small immediate rewards in ADHD, as found in previous research, depend on factors such as total maximum gain and the use of fixed versus varied delay durations. The decrease in TD as observed in adolescents compared to children may be related to developmental changes in the (dorsolateral) prefrontal cortex. Future research needs to investigate

The frequency and severity of a permanent lesion after brachial plexus birth palsy (BPBP) and its impact on activities of daily living are not well documented. We therefore investigated the outcome of BPBP in adolescents, regarding arm function and consequences for activity and participation. Of 30,574 babies born at St. Olavs University Hospital in 1991-2000, 91 had BPBP (prevalence 3 per 1,000), and 69 of these individuals were examined at a median age of 14 (10-20) years. The examination included the modified Mallet classification, range of motion, shoulder rotation and grip strength, Assisting Hand Assessment, and Canadian Occupational Performance Measure. Of the 22 subjects who were not examined, 3 could not be traced and 19 reported having no problems in the affected arm. At follow-up, 17 adolescents had a permanent lesion (i.e. individual Mallet subscore below 4) with a median Mallet total score of 15 (9-19), while 52 had good or normal shoulder function (median Mallet total score 25 (23-25)). All participants with a permanent lesion had reduced active shoulder rotation (≤15°), 16 had elbow extension deficit, and 10 had subnormal grip strength. External rotation was considerably weaker in the affected shoulder. In addition, they had ineffective use of the affected arm in bimanual activities. Even so, all except 1 were independent in activities of daily living, although 15 experienced minor difficulties. Every fourth to fifth child with BPBP had a permanent lesion as an adolescent. External rotation was the most impaired movement. Despite ineffective use of the affected arm in bimanual activities, all of the participants except one were independent in activities of daily living.

2003-01-01

To describe the characteristics of body modification among adolescents and to determine whether adolescents who engage in body modification are more likely to screen positive for alcohol and other drug problems than those who do not. Adolescents aged 14 to 18 years presenting to an urban adolescent clinic for routine health care completed a questionnaire about body modification and a substance use assessment battery that included the 17-item Problem Oriented Screening Instrument for Teenagers Alcohol/Drug Use and Abuse Scale (POSIT-ADS). Body modification was defined as piercings (other than one pair of bilateral earlobe piercings in females), tattoos, scarification, and branding. Problem substance use was defined as a POSIT-ADS score > or =1. Data were analyzed using logistic regression to determine whether the presence of body modification was an independent predictor of problem substance use. The 210 participants had a mean (+/- SD) age of 16.0 (+/- 1.4) years and 63% were female. One hundred adolescents (48%) reported at least one body modification; girls were more likely than boys to have body modification (59% vs. 28%, p < or = .0005). Ninety (42%) reported piercings, 22 (10%) tattoos, 9 (4%) scarification, and 1 (< 1%) branding; 21 (10%) had more than one type of body modification. These were in a variety of locations, most commonly the ear and the nose (piercings) or the extremities (tattoos). One-third of the sample (33%) screened positive for problem substance use on the POSIT-ADS questionnaire. Controlling for age, adolescents with body modification had 3.1 times greater odds of problem substance use than those without body modification (95% CI 1.7, 5.8). Body modification was associated with self-reported problem alcohol and other drug use among middle adolescents presenting for primary care. More research is needed to determine the clinical and sociocultural significance of body modification and its relationship to substance use in this population

Pressure among young athletes to meet body composition goals may lead to poor nutrition and affect growth. To examine the proportion of body fat (%BF), measured by bioimpedance analysis, among Latvian children and adolescents participating in organized sports. Our study had a nationally representative sample of 6048 young athletes, aged 10-17 years. Their %BF was measured using a multifrequency, 8-pole, bioelectrical impedance leg-to-hand analyzer. About 19.2% (CI 14.4-20.0) of boys and 15.1% (CI 14.0-16.3) of girls had a %BF value below the recommended levels. The %BF in young female athletes participating in aesthetic sports was lower than among their peers participating in other sports. Young male athletes participating in aesthetic sports had lower %BF levels at 10 and 12 years of age, compared with participants in weight-class sports; and lower levels of %BF from age 10-14 years, compared with participants in non-weight-sensitive sports. Almost every fifth child and adolescent participating in organized sports displayed critically low body fat levels. Body fat needs to be assessed regularly in young athletes, to prevent negative consequences on health. © 2015 the Nordic Societies of Public Health.

Catatonic features in adolescents with schizophrenia with and without a comorbid pervasive developmental disorder

PubMed Central

2014-01-01

Background Catatonia has been associated with both schizophrenia and pervasive developmental disorders. The aim of this study was to evaluate catatonic features among adolescents suffering from schizophrenia. Further, we compared these features between adolescents with a comorbid pervasive developmental disorder and those without one. Finally, we wanted to compare the profile of catatonia-like features of our schizophrenia patients to that described earlier among persons with autism spectrum disorders. Methods The study comprised a consecutive sample of 18 adolescents with schizophrenia (mean age 15.6 years, SD 1.4) and their families. Diagnosis of schizophrenia was assessed with the Schedule for Affective Disorders and Schizophrenia for School-Aged Children – Present and Life-Time (K-SADS-PL) for the DSM-IV. The Diagnostic Interview for Social and Communication Disorders version 11 was used to assess catatonic features. Results All adolescents with schizophrenia had showed some lifetime catatonic features. Approximately 78% of them had already expressed these features before the age of 10. The number of catatonic features before the age of 10 was significantly higher among the adolescents with a comorbid pervasive developmental disorder compared to those without one. The numbers of catatonic features after the age of 10 did not significantly differ between the two groups. Over three-quarters of schizophrenia patients shared four lifetime catatonic features: “lacks facial expression”, “odd intonation”, “poor eye contact” and “lack of cooperation”. Conclusions Adolescent schizophrenia patients with a comorbid pervasive developmental disorder show many catatonic features in childhood whereas those without one seem to develop these features first in adolescence. Catatonic features exhibited by adolescents with schizophrenia resemble those described among persons with pervasive developmental disorders without schizophrenia. PMID:24914405

To explore the effect of low birthweight on quality of life, the parent-child relationship and the parents' mental health. DESIGN/STUDY GROUPS: A population-based follow-up of 56 very-low-birthweight (age (birthweight<10th centile) and 83 term control adolescents (birthweight>or=10th centile) at 14 y of age. Child Health Questionnaire (Child Form, Parent Form), Parental Bonding Instrument rated by adolescents and parents; Symptom Checklist-90-Revised rated by mothers and fathers. There were no group differences in self-reported health or self-esteem. Parents reported more behavioural problems and lower psychosocial health for very-low-birthweight adolescents (p<0.001) compared with controls. Results did not differ significantly between small-for-gestational-age and control adolescents. The youngsters, their mothers and fathers perceived the same amount of relational warmth in all three groups. Very-low-birthweight parents reported more emotional impact than control parents, especially in the presence of psychiatric problems and cerebral palsy. There were no group differences in mothers' or fathers' mental health. The low-birthweight adolescents perceived quality of life as others did, but the parents reported functional disadvantages for the very-low-birthweight group. Birthweight did not influence the warmth in the parent-child relationship. Parents of very-low-birthweight adolescents experienced increased emotional burden, but they did not have more mental health problems than others.

Parental employment status and adolescents' health: the role of financial situation, parent-adolescent relationship and adolescents' resilience.

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

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.

The dynamic role of parental influences in preventing adolescent smoking initiation.

2013-04-01

As adolescents grow, protective parental influences become less important and peer influences take precedence in adolescent's initiation of smoking. It is unknown how and when this occurs. We sought to: prospectively estimate incidence rates of smoking initiation from late childhood through mid-adolescence, identify important risk and protective parental influences on smoking initiation, and examine their dynamic nature in order to identify key ages. Longitudinal data from the National Survey of Parents and Youth of 8 nationally representative age cohorts (9-16 years) of never smokers in the U.S. were used (N=5705 dyads at baseline). Analysis involved a series of lagged logistic regression models using a cohort-sequential design. The mean sample cumulative incidence rates of tobacco use increased from 1.8% to 22.5% between the 9 and 16 years old age cohorts. Among risk factors, peer smoking was the most important across all ages; 11-15 year-olds who spent time with peers who smoked had 2 to 6.5 times higher odds of initiating smoking. Parent-youth connectedness significantly decreased the odds of smoking initiation by 14-37% in 11-14 year-olds; parental monitoring and punishment for smoking decreased the odds of smoking initiation risk by 36-59% in 10-15 year-olds, and by 15-28% in 12-14 year-olds, respectively. Parental influences are important in protecting against smoking initiation across adolescence. At the same time, association with peers who smoke is a very strong risk factor. Our findings provide empirical evidence to suggest that in order to prevent youth from initiating smoking, parents should be actively involved in their adolescents' lives and guard them against association with peers who smoke.

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.

Since developmental psychologists are interested in explaining age and gender differences in depression across adolescence, it is important to investigate to what extent these observed differences can be attributed to measurement bias. Measurement bias may arise when the phenomenology of depression varies with age or gender, i.e., when younger versus older adolescents or girls versus boys differ in the way depression is experienced or expressed. The Children's Depression Inventory (CDI) was administered to a large school population (N = 4048) aged 8-17 years. A 4-factor model was selected by means of factor analyses for ordered categorical measures. For each of the four factor scales measurement invariance with respect to gender and age (late childhood, early and middle adolescence) was tested using item response theory analyses. Subsequently, to examine which items contributed to measurement bias, all items were studied for differential item functioning (DIF). Finally, it was investigated how developmental patterns changed if measurement biases were accounted for. For each of the factors Self-Deprecation, Dysphoria, School Problems, and Social Problems measurement bias with respect to both gender and age was found and many items showed DIF. Developmental patterns changed profoundly when measurement bias was taken into account. The CDI seemed to particularly overestimate depression in late childhood, and underestimate depression in middle adolescent boys. For scientific as well as clinical use of the CDI, measurement bias with respect to gender and age should be accounted for. © 2012 The Authors.

The prevalence of obesity is increasing rapidly and abdominal obesity especially is known to be a risk factor for metabolic syndrome and other non-communicable diseases. Waist circumference percentile curves are useful tools which can help to identify abdominal obesity among the childhood and adolescent populations. To develop age- and sex-specific waist circumference (WC) percentile curves for multi-ethnic Malaysian children and adolescents aged 6.0-16.9 years. Subjects and methods. A total of 16,203 participants comprising 8,093 boys and 8,110 girls recruited from all regions of Malaysia were involved in this study. Height, weight, WC were measured and BMI calculated. Smoothed WC percentile curves and values for the 3rd, 5th, 10th, 25th, 50th, 75th, 90th, 95th and 97th percentiles were constructed using the LMS Method. WC was found to increase with age in both sexes, but boys had higher WC values at every age and percentile. Z-scores generated using the UK reference data shows that Chinese children had the highest WC compared to Malays, Indians and other ethnicities. Comparisons with other studies indicate that at the 50th percentile, Malaysian curves did not differ from the UK, Hong Kong and Turkish curves, but at the 90th percentile, Malaysian curves were higher compared with other countries, starting at 10 years of age. The 90th percentile was adopted as the cut-off point to indicate abdominal obesity in Malaysian children and adolescents. These curves represent the first WC percentiles reported for Malaysian children, and they can serve as a reference for future studies.

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.

Children and adolescents with the high bone turnover comprise a high risk population for vitamin D insufficiency. A sample of 178 clinically healthy children aged 3 to 18 years who came from public schools and lived in North West of Greece participated in the study. They were grouped into three age groups (I: 3-10, II: 11-14 and III: 15-18 years of age). Blood samples were taken during winter and summer months for determining calciotropic hormones, calcium, phosphate and biochemical markers of bone synthesis.A high percentage (47%) of the subjects aged 15-18 years was found to have 25OHD <10 ng/ml in winter but much less (13-14%) of the younger ages (13-14 years), while in the summer they were all >10 ng/ml. The prevalence was even higher in the girls of the older group accompanied by lower Pi concentrations again in winter (win:1.19+/-0.03, sum:1.93+/-0.03 mmol/l, p < 0.001). The 24,25(OH)(2)D levels were changing in parallel to 25OHD, but again in the older subjects, during winter, they were by 2/3 lower than the summer ones (0.73+/-0.10 vs. 2.41+/-0.20 ng/ml, p < 0.001). No significant differences were found between seasons and groups in the 1,25(OH)(2)D levels. The biochemical markers of bone synthesis, osteocalcin (OC) and total alkaline phosphatase (ALP), were found significantly lower in the girls of the older group both in winter and summer respectively. Even in a sunny country like Greece the adolescents living in an urban area are in high risk for vitamin D deficiency during winter. Supplementation with vitamin D of milk, of popular beverages and perhaps some foods would be of help.

Among 1657 children and adolescents aged 6 to 14 years (787, 47% girls and 870, 53% boys) from primary and secondary schools in a 14-town Southern Italian community, HDL cholesterol (54 ± 15 mg/dl), triglycerides (61 ± 29 mg/dl), blood glucose (78 ± 10 mg/dl), systolic (101 ± 11 mm Hg) and diastolic (62 ± 10 mm Hg) blood pressures, waist circumference (WC) (66 ± 10 cm) and WC/height (0.46 ± 0.006) and triglycerides/HDL cholesterol (1.31 ± 0.99) ratios were measured. The distributions were similar in both genders. Age did not affect triglycerides/HDL cholesterol ratio, whereas there was a slightly positive correlation (p<0.00001) between WC/height and triglycerides/HDL cholesterol ratios. We present individual gender and age specific percentile distributions (as Supplementary materials). Using percentile cut-offs (≤ 10th for HDL cholesterol and ≥ 90th for the other components), there were 183 (11%) children or adolescents with low HDL cholesterol, 162 (9.77%) with high triglycerides, 178 (10.74%) with high blood glucose, 178 (10.74%) with high WC, 244 (20.76%) with high systolic or diastolic BP and 126 (7.6%) with high systolic and diastolic BP. Abnormally high BP was seen in 470 (28.36%) children or adolescents. Using abnormal percentile values of 3 of 5 of its components, metabolic syndrome (MS) was diagnosed in 70 (4.2%) subjects, similarly in both genders. To assess out-of-limit distributions of all 5 individual MS components in children and adolescents gender- and age-distributions derived from local epidemiological data should be used: these distributions are presented and they might now be used both for comparative and applicative purposes at least in Southern Europe.

To describe the association of sunscreen use, sunburning, and tanning bed use by age, sex, residence, and psychosocial variables associated with tan-seeking behaviors, and to compare these findings with sun protection recommendations from federal agencies and cancer organizations. A cross-sectional study, from all 50 states, of 10 079 boys and girls 12 to 18 years of age in 1999. Data were collected from self-report questionnaires with the children of the participants from the Nurses Health Study (Growing Up Today Study). The prevalence of sunscreen use was 34.4% with girls more likely to use sunscreen than boys (40.0 vs 26.4, odds ratio: 1.86; 95% confidence interval: 1.70-2.03). Eighty-three percent of respondents had at least 1 sunburn during the previous summer, and 36% had 3 or more sunburns. Nearly 10% of respondents used a tanning bed during the previous year. Girls were far more likely than boys to report tanning bed use (14.4 vs 2.4), and older girls (ages 15-18) were far more likely than younger girls (ages 12-14) to report tanning bed use (24.6% vs 4.7). Tanning bed use increased from 7% among 14-year-old girls to 16% by age 15, and more than doubled again by age 17 (35%; N = 244). Multivariate analysis demonstrated that attitudes associated with tanning, such as the preference for tanned skin, having many friends who were tanned, and belief in the worth of burning to get a tan, were generally associated with sporadic sunscreen use, more frequent sunburns, and increased use of tanning beds. Our findings suggest that many children are at subsequent risk of skin cancer because of suboptimal sunscreen use, high rates of sunburning, and tanning bed use. Recommendations in the United States for improved sun protection and avoidance of tanning beds and sunburning, which began in the early 1990s, have been primarily unheeded. Nationally coordinated campaigns with strong policy components must be developed and sustained to prevent skin cancer in a new generation

To describe behavior problems in extremely low birth weight (ELBW, <1000 g) adolescents born 1992 through 1995 based on parent ratings and adolescent self-ratings at age 14 years and to examine changes in parent ratings from ages 8-14. Parent ratings of behavior problems and adolescent self-ratings were obtained for 169 ELBW adolescents (mean birth weight 815 g, gestational age 26 wk) and 115 normal birth weight (NBW) controls at 14 years. Parent ratings of behavior at age 8 years were also available. Behavior outcomes were assessed using symptom severity scores and rates of scores above DSM-IV symptom cutoffs for clinical disorder. The ELBW group had higher symptom severity scores on parent ratings at age 14 years than NBW controls for inattentive attention-deficit hyperactivity disorder (ADHD), anxiety, and social problems (all p's < .01). Rates of parent ratings meeting DSM-IV symptom criteria for inattentive ADHD were also higher for the ELBW group (12% vs. 1%, p < .01). In contrast, the ELBW group had lower symptom severity scores on self-ratings than controls for several scales. Group differences in parent ratings decreased over time for ADHD, especially among females, but were stable for anxiety and social problems. Extremely low birth weight adolescents continue to have behavior problems similar to those evident at a younger age, but these problems are not evident in behavioral self-ratings. The findings suggest that parent ratings provide contrasting perspectives on behavior problems in ELBW youth and support the need to identify and treat these problems early in childhood.

ABSTRACT OBJECTIVE To describe the prevalence of asthma and physician-diagnosed asthma in Brazilian adolescents. METHODS Cross-sectional, national, school-based study with adolescents from 12 to 17 years old, participants in the Study of Cardiovascular Risks in Adolescents (ERICA). The study stratified the sample by region and grouped according to schools and classes with representativeness to the set of cities with more than 100,000 inhabitants of the Country, macro-regions, capitals, and Federal District. A questionnaire collected data through a self-filled in method. We calculated the prevalences and their confidence intervals of 95% (95%CI) according to sex, age group, type of school and skin color. RESULTS Between 2013 and 2014, 74,589 adolescents were evaluated, 55.3% of the female sex. The total prevalence of active asthma was of 13.1% (95%CI 12.1-13.9), being higher in girls (14.8%; 95%CI 13.7-16.0) when compared to boys (11.2%; 95%CI 10.3-12.2) in all geographical strata examined. It was also higher between students of private schools (15.9%; 95%CI 14.2-17.7) when compared to public ones (12.4%; 95%CI 11.4-13.4). It was higher in the Southeast region (14.5%; 95%CI 12.9-16.1), and in the city of Sao Paulo (16.7%; 95%CI 14.7-18.7). The lowest prevalence was observed in North region (9.7%; 95%CI 9.7-10.5), and in Teresina (6.3%; 95%CI 4.9-7.7). The prevalence of physician-diagnosed asthma was of 8.7% (95%CI 8.2-9.1); higher in the North region (13.5%; 95%CI 12.7-14.2), and in Porto Alegre (19.8%; 95%CI 17.5-22.3). It was lower in the Midwest (6.9%; 95%CI 6.0-7.8), and in Cuiaba (4.8%; 95%CI 3.8-5.9). We found no significant difference in the expression of this rate between the sexes, as well as in other variables evaluated by the study. CONCLUSIONS The prevalence of asthma in Brazilian adolescents is high. Rates of active asthma and physician-diagnosed asthma vary widely in different regions and capitals evaluated by the ERICA. These results may assist in the

BACKGROUND. The study aimed to determine the prevalence and patterns of spinal pain (SP) among Polish adolescents as well as the impact of the pain on their daily life activities. Moreover, it analysed the potential effect of extracurricular physical activity on back pain prevalence, frequency and consequent functional limitations among adolescents. MATERIAL AND METHODS. The study involved 2,676 students aged 13 to 19 years enrolled from three randomly selected administrative regions of Poland. The participants completed a survey designed by the authors during their classes. RESULTS. Sixty-five per cent of respondents reported having had back pain and 48% described the episodes as recurring. The pain was most frequently located in the lumbosacral spine and most commonly occurred for the first time in adolescents between 13 and 15 years of age. The most significant pain-related functional limitation was noted for physical activity, sitting, learning and concentration and lifting objects. CONCLUSIONS. 1. The prevalence of back pain in Polish adolescents is similar to relevant figures given for adults and their peers in Western Europe. 2. Spinal pain may significantly affect performance of daily activities by adolescents. Further studies should investigate strategies of pain management in this age group in more detail. 3. Regular exercise does not prevent back pain but it may reduce the functional limitations and stimulate recovery of complete capacity.

While cognitive and emotional systems both undergo development during adolescence, few studies have explored top-down inhibitory control brain activity in the context of affective processing, critical to informing adolescent psychopathology. In this study, we used functional magnetic resonance imaging to examine brain response during an Emotional Conflict (EmC) Task across 10–15-year-old youth. During the EmC Task, participants indicated the emotion of facial expressions, while disregarding emotion-congruent and incongruent words printed across the faces. We examined the relationships of age, sex, and gonadal hormones with brain activity on Incongruent vs. Congruent trials. Age was negatively associated with middle frontal gyrus activity, controlling for performance and movement confounds. Sex differences were present in occipital and parietal cortices, and were driven by activation in females, and deactivation in males to Congruent trials. Testosterone was negatively related with frontal and striatal brain response in males, and cerebellar and precuneus response in females. Estradiol was negatively related with fronto-cerebellar, cingulate, and precuneus brain activity in males, and positively related with occipital response in females. To our knowledge, this is the first study reporting the effects of age, sex, and sex steroids during an emotion-cognition task in adolescents. Further research is needed to examine longitudinal development of emotion-cognition interactions and deviations in psychiatric disorders in adolescence. PMID:26175008

Background More perinatally HIV-infected children in Asia are reaching adolescence. Methods We analyzed data from July 1991 to March 2011 reported by 18 clinics in six countries of children age >12 years. Results Of 1,254 adolescents, 33 (2.6%) died, and 52 (4.2%) were lost to follow-up within 2.4-year (3566 person-years) median follow-up period. Of 1,061 adolescents under active follow-up, 485 (46%) were male, median (IQR) age was 14.7 (13.3-16.4) years, 73% had lost a parent(s), 93% attended school, and 62% were aware of their HIV status. At the most recent evaluation, 93% were receiving highly active antiretroviral therapy (ART), 71% (N=737/1035) had CD4 >500 cells/mm3 and 86% (N=718/830) had viral load (VL) <400 copies/mL. Current CD4 >200 cells/mm3, no previous WHO stage 3 or 4, and being on a first-line regimen were independently associated with recent VL <400 copies/mL. Current age <15 years, VL <400 copies/ml, CD4 15-24% (vs. <10%) at ART initiation, no previous WHO stage 3 or 4, and ART duration of >1 year were associated with recent CD4 >500 cells/mm3.Primary causes of death after age 12 were opportunistic infections (N=15/33) and other AIDS- or treatment-related conditions (N=9/33). Those at age 12 with CD4 <200 vs. >500 cells/mm3 and those with VL >10,000 vs. <10,000 copies/mL were 17.4 and 4.76 times more likely to die in adolescence, respectively. Conclusion Adolescents in this cohort have been successfully maintained in HIV care. Initiating treatment at earlier stages of disease was associated with immune recovery and virologic suppression during adolescence. PMID:23942457

Injuries are the leading cause of death among adolescents. The current research examined a measure of adolescent injury in terms of whether it encompasses the diverse injury experiences of Australian adolescents, including high-risk and normative adolescents, and thus determine its utility as a tool for health promotion research. Grade 9 students from two Brisbane high schools (n=202, aged 13-14 years) and adolescents recruited from the Emergency Department waiting rooms of four Brisbane hospitals (n=98, aged 16-18 years) completed the Extended Adolescent Injury Checklist (E-AIC). The most common cause of injury among adolescents was a sports activity, followed by fights for all participants except school-based males, who experienced more bicycle injuries. Alcohol use was most frequently reported in association with interpersonal violence injuries. A broad variety of injuries, occurring in context of multiple risk as well as normative behaviours, were reported by adolescents in both school and ED settings, and were captured by the E-AIC.

Sexually transmitted infections (STIs) are major causes of medical and psychological problems globally, while adolescents in South Korea have recently shown rapid changes in sexual behaviors. We aimed to examine the association between the age of first sexual intercourse and the experience of STIs among adolescents. Additionally, in which specific time period would more likely to get infected from sexual intercourse. We used data from the 2007-2013 Korea Youth Risk Behavior Web-based Survey. Only adolescents with sexual intercourse experience (N = 22,381) were included, and multiple logistic regression analysis was performed. One dichotomized measure and one continuous measure were assessed: (i) STIs experience (defined as having had STIs); and (ii) association between STIs experience and absolute age gap (defined as temporal differences between secondary sexual character emergence age and first sexual intercourse age). Approximately 7.4% of boys and 7.5% of girls reported had STI. For both boys and girls, the chance of experiencing STIs increased as the age of first sexual intercourse decreased (boys: before elementary school [age 7 or under]: odds ratio [OR] = 10.81, first grade [age 7 or 8]: OR = 4.44, second grade [age 8 or 9]: OR = 8.90, fourth grade [age 10 or 11]: OR = 7.20, ninth grade [age 15 or 16]: OR = 2.31; girls: before elementary school: OR = 18.09, first grade: OR = 7.26, second grade: OR = 7.12, fourth grade: OR = 8.93, ninth grade: OR = 2.74). The association between the absolute age gap and STI experience was examined additionally (boys: OR = 0.93, girls: OR = 0.87). This study shows that earlier initiation of sexual intercourse increases the odds of experiencing STIs. Also as the age gap gets shorter, the odds of experiencing STIs increase. Our study suggests that it is important to consider the time period of first sexual intercourse and to reinforce a monitoring system along with the

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.

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.

2018-06-01

Although research increasingly addresses the role of parenting in fostering adolescent disclosure, most research relied on self-report measures of parenting and did not address the role of autonomy support. In the present observational study (conducted in Belgium), with 62 mother-adolescent dyads (mean age mothers = 44 years; mean age adolescents = 14 years; 77% of adolescents female), we rated mothers' provision of autonomy support during a 10-minute conversation about friendships. We found that observed maternal autonomy support was related positively to adolescents' degree of and volitional reasons for disclosure about friends. These associations were mediated by observed non-verbal reciprocity during the conversation and by adolescent satisfaction of their needs for autonomy and relatedness. Mothers' autonomy-support and mother-adolescent reciprocity also predicted mothers' own psychological need satisfaction and conversation pleasure. The relevance of the findings for adolescent autonomy and disclosure are discussed. Copyright © 2018. Published by Elsevier Ltd.

Paul, Christine; Tzelepis, Flora; Parfitt, Nicholas; Girgis, Afaf

2008-01-01

To explore adolescents' self-reported reasons for sun protection, as adolescents as a group continue to have poor sun protection practices. Seventeen age- and gender-segregated focus groups were conducted in Australian high schools. Reasons for using sun protection included personal comfort, appearance, policies, fear of skin cancer, expectations of authority figures, peer actions, and habit. Reasons for not using sun protection included desire for a tan, inconvenience, low perceived risk, and fashion. Age and gender effects were found. Avenues for intervention with adolescents include authority figures, peer advocacy, the fashion industry, and improved sun protection products.

Sibling Relationships and Adolescent Adjustment: Longitudinal Associations in Two-Parent African American Families

Whiteman, Shawn D.; Solmeyer, Anna R.; McHale, Susan M.

2015-01-01

Sibling relationships have been described as love-hate relationships by virtue of their emotional intensity, but we know little about how sibling positivity and negativity operate together to affect youth adjustment. Accordingly, this study charted the course of sibling positivity and negativity from age 10 to 18 in African American sibling dyads and tested whether changes in relationship qualities were linked to changes in adolescents’ internalizing and externalizing behaviors. Participants were consecutively-born siblings (at Time 1, older siblings averaged 14.03 (SD = 1.80) years of age, 48% female; younger siblings averaged 10.39 (SD = 1.07) years of age, 52% female) and two parents from 189 African American families. Data were collected via annual home interviews for three years. A series of multi-level models revealed that sibling positivity and sibling negativity declined across adolescence, with no significant differences by sibling dyad gender constellation. Controlling for age-related changes as well as time-varying parent-adolescent relationship qualities, changes in sibling negativity, but not positivity, were positively related to changes in adolescents’ depressive symptoms and risky behaviors. Like parent-adolescent relationships, sibling relationships displayed some distancing across adolescence. Nevertheless, sibling negativity remained a uniquely important relational experience for African American adolescents’ adjustment. PMID:25893573

Aged rats are more vulnerable than adolescents to "ecstasy"-induced toxicity.

3,4-Methylenedioxymethamphetamine (MDMA or "ecstasy") is a widespread drug of abuse with known neurotoxic properties. The present study aimed to evaluate the differential toxic effects of MDMA in adolescent and aged Wistar rats, using doses pharmacologically comparable to humans. Adolescent (post-natal day 40) (3 × 5 mg/kg, 2 h apart) and aged (mean 20 months old) (2 × 5 mg/kg, 2 h apart) rats received MDMA intraperitoneally. Animals were killed 7 days later, and the frontal cortex, hippocampus, striatum and cerebellum brain areas were dissected, and heart, liver and kidneys were collected. MDMA caused hyperthermia in both treated groups, but aged rats had a more dramatic temperature elevation. MDMA promoted serotonergic neurotoxicity only in the hippocampus of aged, but not in the adolescents' brain, and did not change the levels of dopamine or serotonin metabolite in the striatum of both groups. Differential responses according to age were also seen regarding brain p-Tau levels, a hallmark of a degenerative brain, since only aged animals had significant increases. MDMA evoked brain oxidative stress in the hippocampus and striatum of aged, and in the hippocampus, frontal cortex, and striatum brain areas of adolescents according to protein carbonylation, but only decreased GSH levels in the hippocampus of aged animals. The brain maturational stage seems crucial for MDMA-evoked serotonergic neurotoxicity. Aged animals were more susceptible to MDMA-induced tissue damage in the heart and kidneys, and both ages had an increase in liver fibrotic tissue content. In conclusion, age is a determinant factor for the toxic events promoted by "ecstasy". This work demonstrated special susceptibility of aged hippocampus to MDMA neurotoxicity, as well as impressive damage to the heart and kidney tissue following "ecstasy".

Estimate sexual activity among Congolese adolescents in Brazzaville and appreciate the influence of sociocultural and economic factors on sexual behaviour. Data were collected from 900 adolescents (389 males and 511 females) aged 10-19 years in the seven urban areas of Brazzaville. These subjects were randomly recruited by a two stage sampling. The data were gathered by an anonymous face-to-face questionnaire. Relative risk estimations were calculated for early or first sexual intercourse, multiple sexual partnerness and safe sex. A total of 474 respondents indicated that they were sexually active. Females were more sexually active, 270 compared with 204 males (p<0.05). The mean early age of coital debut was 14.6 years (S.D.=1.7 years). Early intercourse (before 14 years) was found in 73 males and 39 females (p<0.001). Multiple sexual partnerness was found in 81.3% of males, while the frequency of females was 51.1%. Risk factors for pregnancy and multiple sexual partnerness were unemployment mother, non school situation, early puberty and non sexual education. In contrast, regular religious activity was recognized as factor that had significant protection impact on sexual activity. The total use ratio of the condom was estimated at 42.2% in males. More females (41.7%) were using Ogino method of contraception. In addition, 102 females (36.8%) claimed to have already a pregnancy and the mean age was 16.1 years (S.D.=1.2 years). In 64.7% of these cases, teenagers chose the abortion as solution of an unwanted pregnancy. After the birth of a child, it was reported that 82.4% of adolescents gave up with school. Our results show the importance of problems associated to sexual activity among Congolese adolescents in Middle Africa. These data should be taken into account when planning the prevention of risk of sexual behaviours among adolescents.

ICD-10 classification in Danish child and adolescent psychiatry--have diagnoses changed after the introduction of ICD-10?

PubMed

Møller, Lene Ruge; Sørensen, Merete Juul; Thomsen, Per Hove

2007-01-01

The aim was to test this in a nationwide register study of diagnoses used in child and adolescents psychiatry in Denmark. A larger number of different diagnoses were expected to be applied after the introduction of the 10th version of the International Classification of Diseases (ICD-10). Reflecting the time trend, we particularly expected an increase in the number of neuropsychiatric diagnoses. From the Danish Psychiatric Central Register data were drawn on clinical discharge diagnoses. All patients aged 0-15 years examined at psychiatric hospitals from 1995-2002 were included; 22,469 children and adolescents with a first contact were registered. The most frequent discharge diagnoses were pervasive development disorders (PDD; 11.9%), adjustment disorders (10.6%), conduct disorder (9.5%), emotional and anxiety disorders (7.6%), hyperkinetic disorders (7.3%), and specific developmental disorders (7.3%). We found a significant increase in the number of neuropsychiatric and affective diagnoses and a significant decrease in the number of adjustment, conduct and anxiety diagnoses during the study period. Of the 22,469 diagnoses, 45% were only partly specified according to ICD-10. Thirty-four per cent had diagnoses unspecified on the four-character level (Fxx.9) and 11% had Z-diagnoses. A larger number of different diagnoses and an increase in the use of neuropsychiatric diagnoses were seen after the introduction of ICD-10. Many diagnoses were only partly specified; consequently, a more detailed specification of the ICD-10 is still required.

Adolescent femicide: a population-based study.

Homicide is the third leading cause of deaths for girls aged 11 to 14 years and the second leading cause of death for girls aged 15 to 18 years. However, few studies examine the contextual issues of adolescent femicide, especially among 11- to 14-year-old victims. To obtain quantitative and contextual information about adolescent femicide, and to compare the context of femicide in younger vs older adolescents. Data from the North Carolina medical examiner were analyzed for all 11- to 18-year-old female homicide victims during 1990 to 1995. Police interviews were conducted for 1993 to 1995 cases to determine context, the relationship of victim and perpetrator, and criminal histories. There were 90 victims; 63 were aged 15 to 18 years, 55 were killed with firearms, and 40 were behind in school. Of 37 femicides for which law enforcement interviews were conducted, the most common contexts were altercation (n = 9), broken or desired relationship (n = 8), reckless behavior with a firearm (n = 6), retaliation (n = 5), and drug related (n = 3). Most perpetrators were men (89%; n = 33), were older than their victims (mean age difference, 8 years), and had criminal records (59%; n = 21). Seventy-eight percent of victims (n = 29) were killed by an acquaintance or intimate partner. Femicide contexts differed by age. Younger adolescents (aged 11-14 years) were more likely to be killed by a family member in the context of an argument than by an intimate partner or acquaintance in the context of a broken relationship or reckless behavior with a firearm. Many victims were engaged in high-risk behaviors, including dropping out of school, running away from home, using drugs, and dating much older men with criminal records. Intervention specialists targeting high-risk female adolescents should be aware that this population may also be at increased risk of femicide.

The influence of electronic cigarette age purchasing restrictions on adolescent tobacco and marijuana use.

Pesko, Michael F; Hughes, Jenna M; Faisal, Fatima S

2016-06-01

In the United States, many states have established minimum legal purchase ages for electronic nicotine delivery systems (ENDS) to ban adolescent purchases, but these policies may also affect other related substance use. We explore whether ENDS are substitutes or complements for cigarettes, cigars, smokeless tobacco, and marijuana among adolescents by using variation in state-level implementation of ENDS age purchasing restrictions. We linked data on ENDS age purchasing restrictions to state- and year-specific rates of adolescent tobacco and marijuana use in 2007-2013 from the Youth Risk Behavior Surveillance System. This data provides a nationally representative sample of adolescents who attend public and private schools. We performed a fixed effect regression analysis exploring the influence of ENDS age purchasing restrictions on outcomes of tobacco use and marijuana use, controlling for state and year fixed characteristics, age-race cohorts, cigarette excise taxes, and cigarette indoor use restrictions. For cigarette use, we separate our results into cigarette use frequency. We found causal evidence that ENDS age purchasing restrictions increased adolescent regular cigarette use by 0.8 percentage points. ENDS age purchasing restrictions were not associated with cigar use, smokeless tobacco use, or marijuana use. We document a concerning trend of cigarette smoking among adolescents increasing when ENDS become more difficult to purchase. Copyright © 2016 Elsevier Inc. All rights reserved.

2013-09-01

During the last 10 years, the use of psychotropic medications in youth with psychiatric disorders, including eating disorders, has significantly increased, but their role in the treatment of adolescent anorexia nervosa is still controversial. This paper aims to review the literature on the use of antidepressants and antipsychotics in adolescents with anorexia nervosa, comparing the efficacy and tolerability in this population with those reported in trials with patients not selected by age. A systematic review of the available literature published so far. Only few studies met the selection criteria. No strong evidence of beneficial effects was found in using antidepressants and antipsychotics neither in adults nor in adolescents. Side effects were more frequently reported in studies including adolescent population. Among psychotropic drugs, the majority of studies focused on olanzapine, which seems to have, in some studies, only positive effects on body mass index, eating disorder symptoms and functional impairment in both age groups.

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.

Dieting and disordered eating behaviors from adolescence to young adulthood: Findings from a 10-year longitudinal study

2011-01-01

Background Disordered eating behaviors are prevalent in adolescence and can have harmful consequences. An important question is whether use of these behaviors in adolescence sets the pattern for continued use into young adulthood. Objective To examine the prevalence and tracking of dieting, unhealthy and extreme weight control behaviors, and binge eating from adolescence to young adulthood. Design Population-based, 10-year longitudinal study (Project EAT-III: Eating Among Teens and Young Adults, 1999–2010). Participants/setting The study population includes 2,287 young adults (55% female, 52% non-white). The sample includes a younger group (mean age = 12.8±0.7 years at baseline and 23.2±1.0 years at follow-up) and an older group (mean age = 15.9±0.8 at baseline and 26.2±0.9 years at follow-up). Statistical analyses performed Longitudinal trends in prevalence of behaviors were tested using generalized estimating equations. Tracking of behaviors were estimated using the relative risk of behaviors at follow-up given presence at baseline. Results In general, the prevalence of dieting and disordered eating was high and remained constant, or increased, from adolescence to young adulthood. Furthermore, behaviors tended to track within individuals and, in general, participants who engaged in dieting and disordered eating behaviors during adolescence were at increased risk for these behaviors ten years later. Tracking was particularly consistent for the older females and males transitioning from middle adolescence to middle young adulthood. Conclusions Study findings indicate that disordered eating behaviors are not just an adolescent problem, but continue to be prevalent among young adults. The tracking of dieting and disordered eating within individuals suggests that early use is likely to set the stage for ongoing use. Findings suggest a need for both early prevention efforts prior to the onset of harmful behavioral patterns, as well as ongoing prevention and

Goncy, Elizabeth A; Mrug, Sylvie

2013-03-01

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.

Sleep and adolescent suicidal behavior.

Liu, Xianchen

2004-11-01

Suicide risk begins to increase during adolescence. Adolescents do not get enough sleep and are also at risk for many sleep disturbances. This study examined the association between sleep patterns and sleep problems and adolescent suicidal behavior. A questionnaire survey of adolescents attending school was conducted in one prefecture of Shandong Province, People's Republic of China. A total of 1,362 adolescents attending school (mean age 14.6 years, 60% males) participated in the survey. Respondents completed a self-administered questionnaire that asked about sleep patterns, sleep problems, suicidal behavior, depressive symptoms, and demographic characteristics of the family and adolescent. Overall, 19.3% of the sample reported having suicidal ideation, 10.5% having suicide attempts in the past 6 months, 16.9% having insomnia symptoms, 2.3% having taken hypnotic medication, and 48.9% having experience of nightmares in the past month. Mean night sleep duration was 7.6 hours (SD = 0.8). Logistic regression analyses showed that sleeping less than 8 hours at night (OR = 2.89, 95% confidence interval [CI] = 1.07-7.81) and frequent nightmares (OR = 2.43, 95% CI = 1.76-3.35) were significantly associated with increased risk for suicide attempts after adjustment for age, sex, father's occupation, and depressive symptoms and that nightmares (OR = 1.69, 95% CI = 1.20-2.38) were also significantly related to suicidal ideation. These findings demonstrate the association between short sleep duration and nightmares and suicidal behavior and highlight the potential role of sleep intervention in the prevention of adolescent suicide.

The relationship between body composition and physical fitness in 14 year old adolescents residing within the Tlokwe local municipality, South Africa: The PAHL study

PubMed Central

2012-01-01

Background Little is known about the relationship between body composition and physical fitness in 14 year-old high school adolescents of South Africa. Baseline data from a longitudinal study on physical activity and health (PAHLS) may provide valuable information for future studies, hence to inform public health policy makers. The objectives of this study are to determine the prevalence of underweight, normal weight and overweight among adolescents aged 14 years in the Tlokwe Local Municipality of the North West Province of South Africa, and to assess the association between physical fitness and body composition separately for boys and girls, adjusted for race and locality. Methods Body weight, height and triceps, and subscapular skinfolds of 256 adolescents (100 boys and 156 girls) aged 14 years were measured, and percentage body fat and body mass index (BMI) were calculated. BMI was used to determine underweight, normal weight and overweight based on the standard criterion. Physical fitness was assessed by standing broad jump, bent arm hang and sit-ups according to the EUROFIT fitness standard procedures. Multinomial logistic regression analyses stratified for gender and adjusted for race (black or white), and the locality (urban or township) of the schools were used to analyze the data. Results In the total group 35.9% were underweight and 13.7% overweight. Boys were more underweight (44%) than girls (30.7%). The prevalence of overweight was 8% in boys and 17.3% in girls. BMI was strongly (p = 0.01) related with percentage body fat. Strong and significant positive associations between physical fitness and BMI for the underweight girls with high physical fitness scores (OR, 10.69 [95%CI: 2.81-40.73], and overweight girls with high physical fitness scores (OR, 0.11 [95%CI: 0.03-0.50]) were found. Non-significant weaker positive relationship between physical fitness and BMI for the underweight boys with high physical fitness scores (OR, 1.80 [95%CI: 0

Emergence of electronic cigarette use in US adolescents and the link to traditional cigarette use.

2017-04-01

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.

Recalled Explanations for Adolescent Girls' Engagement in Age-Discordant Sexual Relationships.

Cort, Natalie A; Senn, Theresa E; Carey, Michael P; Braksmajer, Amy

2016-06-01

Age-discordant sexual relationships are associated with negative sexual health outcomes for adolescent females. We were particularly interested in females' motivations for engaging in these relationships, and in contextual factors that increase receptivity to age-discordant relationships in the United States (U.S.). However, recent research addressing this topic in the U.S. has been sparse. To address this gap in the literature, we recruited 15 women (Mdn age = 26 years; 93 % African American) from an urban, publicly funded sexually transmitted disease clinic to qualitative interviews. Reasons given by women for their involvement in age-discordant sexual relationships as adolescents included: (a) desire for an actively engaged father figure, (b) to obtain material support, (c) to escape from a troubled home life, and (d) to express independence and maturity. Thus, familial, economic, and developmental factors motivate socioeconomically disadvantaged adolescent females to enter into age-discordant sexual relationships. Efforts to reduce females' participation in these relationships will need to address socioeconomic vulnerability and family relationships.

Socioemotional Adjustment as a Mediator of the Association between Exposure to Community Violence and Academic Performance in Low-Income Adolescents.

Hardaway, Cecily R; Larkby, Cynthia A; Cornelius, Marie D

2014-07-01

This study examines whether exposure to community violence is indirectly related to academic performance through anxious/depressed symptoms and delinquent behaviors. Three hundred eighteen mothers and adolescents who participated in a longitudinal investigation were interviewed when adolescents were age 10, 14, and 16. Community violence exposure at age 14 was significantly related to anxious/depressed symptoms and delinquent behaviors. Delinquent behaviors (but not anxious/depressed symptoms) were significantly associated with academic performance at age 16. Exposure to community violence was indirectly related to academic performance through delinquent behaviors. There was no significant indirect effect of exposure to community violence on academic performance through anxious/depressed symptoms. Covariates included sociodemographics and exposure to child abuse. Age 10 anxious/depressed symptoms, age 10 delinquent behaviors, and age 14 academic performance were also included in the model to control for preexisting differences in socioemotional adjustment and academic performance. Results suggest that exposure to community violence may initiate a cascade of problems that spread from behavior problems to declines in academic performance. Our results highlight the need for schools to consider exposure to community violence as one form of trauma and to transform in ways that make them more trauma-sensitive. The use of trauma-sensitive practices that address the effects of violence exposure on youth may help limit the progression of adverse effects from delinquent behavior to other domains of functioning.

Asthma often begins early in childhood. However, the risk for persistence is challenging to evaluate. This longitudinal study relates lung function assessed with impulse oscillometry (IOS) in preschool children to asthma in adolescence. Lung function was measured with IOS in 255 children with asthma-like symptoms aged 4-7 years. Baseline measurements were followed by exercise challenge and bronchodilation tests. At age 12-16 years, 121 children participated in the follow-up visit, when lung function was assessed with spirometry, followed by a bronchodilation test. Asthma symptoms and medication were recorded by a questionnaire and atopy defined by skin prick tests. Abnormal baseline values in preschool IOS were significantly associated with low lung function, the need for asthma medication, and asthma symptoms in adolescence. Preschool abnormal R5 at baseline (z-score ≥1.645 SD) showed 9.2 odds ratio (95%CI 2.7;31.7) for abnormal FEV1/FVC, use of asthma medication in adolescence, and 9.9 odds ratio (95%CI 2.9;34.4) for asthma symptoms. Positive exercise challenge and modified asthma-predictive index at preschool age predicted asthma symptoms and the need for asthma medication, but not abnormal lung function at teenage. Abnormal preschool IOS is associated with asthma and poor lung function in adolescence and might be utilised for identification of asthma persistence. Copyright © 2018 The Authors.

Holtz, Peter; Appel, Markus

2011-02-01

In early adolescence, the time spent using the Internet and video games is higher than in any other present-day age group. Due to age-inappropriate web and gaming content, the impact of new media use on teenagers is a matter of public and scientific concern. Based on current theories on inappropriate media use, a study was conducted that comprised 205 adolescents aged 10-14 years (Md = 13). Individuals were identified who showed clinically relevant problem behavior according to the problem scales of the Youth Self Report (YSR). Online gaming, communicational Internet use, and playing first-person shooters were predictive of externalizing behavior problems (aggression, delinquency). Playing online role-playing games was predictive of internalizing problem behavior (including withdrawal and anxiety). Parent-child communication about Internet activities was negatively related to problem behavior. Copyright © 2010 The Association for Professionals in Services for Adolescents.

Age-related policies allow adolescents to access paediatric and adult EDs. Anecdotally, paediatric and adult EDs report challenges when caring for older and younger adolescents, respectively. Our aim was to describe the characteristics of an adolescent population attending an adult ED, co-located with a tertiary paediatric ED. The Westmead Hospital ED database was accessed for 14.5-17.9 years old presentations between January 2010 and December 2012. Patient diagnosis coding (SNOMED) was converted to ICD-10. De-identified data were transferred into Microsoft Excel with analysis performed using spss V22. There were 5718 presentations made to the Westmead Hospital, Sydney, Australia ED by 4450 patients, representing 3.3% (95% CI 3.2-3.4) of total visits from all patients 14.5 years and above. The mean age of the sample was 16.6 years (male 51.8%). Presentations triaged as level 4 or 5 represented 61.0% (95% CI 58.7-61.3) of visits. The proportion of patients who did not wait to receive care was 13.8% (95% CI 12.9-14.7), which was significantly higher than adult rates (P < 0.01). There were 279 unscheduled return visits (visits made <72 h of discharge) representing 4.9% (95% CI 4.4-5.8) of all presentations. Injury was the most common diagnosis (30.2%, 95% CI 28.8-31.6). Chronic physical illness and alcohol-related visits comprised 2.1% (95% CI 1.7-2.5) and 0.8% (95% CI 0.6-1.0) of adolescent presentations, respectively. Contrary to reported staff perceptions, adolescent chronic physical illness presentations were not a major burden. Alcohol was likely under-recorded as a contributing factor to presentations. © 2017 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

2014-01-01

We investigate adolescent risk factors, measured at both early and late adolescence, for involvement in child maltreatment during adulthood. Comprehensive assessments of risk factors for maltreatment that use representative samples with longitudinal data are scarce and can inform multilevel prevention. We use data from the Rochester Youth Development Study, a longitudinal study begun in 1988 with a sample of 1,000 seventh and eighth graders. Participants have been interviewed 14 times and, at the last assessment (age 31), 80% were retained. Risk factors represent 10 developmental domains: area characteristics, family background/structure, parent stressors, exposure to family violence, parent-child relationships, education, peer relationships, adolescent stressors, antisocial behaviors, and precocious transitions to adulthood. Maltreatment is measured by substantiated reports from Child Protective Services records. Many individual risk factors (20 at early adolescence and 14 at later adolescence) are significantly, albeit moderately, predictive of maltreatment. Several developmental domains stand out, including family background/structure, education, antisocial behaviors, and precocious transitions. In addition, there is a pronounced impact of cumulative risk on the likelihood of maltreatment. For example, only 3% of the youth with no risk domains in their background at early adolescence were involved in later maltreatment, but for those with risk in 9 developmental domains the rate was 45%. Prevention programs targeting youth at high risk for engaging in maltreatment should begin during early adolescence when risk factors are already at play. These programs need to be comprehensive, capable of addressing the multiple and interwoven nature of risk that is associated with maltreatment. PMID:24075569

Adolescents' strengths and difficulties: approach to attachment styles.

PubMed

Keskin, G; Cam, O

2010-06-01

This research is a descriptive field study conducted in order to investigate the relationship between adolescent difficulties and the attachment style. The study aims to investigate the relationship between adolescent attachment style and strength and difficulties in Turkey. Children attachment style and difficulties pattern in the group of adolescents aged 11-16 years old were compared with each other. Several different questionnaires, including The Strength and Difficulties Questionnaire, The Relationship Scale Questionnaire were applied to 384 (mean age 12.10 +/- 1.4 years) adolescents. The data were analysed using descriptive statistics, Pearson correlation coefficients, anova, t-test, Kruskall Wallis and effect sizes. The adolescent secure attachment style was associated with increased levels of prosocial behaviour, decreased levels of emotional symptoms, hyperactivity/inattention, peer relationship problems, conduct problems, total difficulties scores. The adolescent fearful attachment style was associated with increased levels of emotional symptoms, and total difficulties scores. The adolescent dismissing attachment style was significantly associated with higher levels of emotional symptoms, hyperactivity/inattention, total difficulties scores and lower levels of prosocial behaviour. Adolescent strengths and difficulties are associated with their attachment style. Insecure attachment styles of dismissing and fearful were associated with increased mental symptom reporting. It is suggested that further studies may illuminate the clinical value of the attachment disorder and quantify parental contribution to psychopathology. Giving the therapeutic, structured mental support programme to adolescents that have attachment problems could be beneficial in improving mental status of these individuals.

2015-01-01

To determine trends in beer, wine, and liquor consumption among Spanish adolescents in 2002, 2006, and 2010, as well as drunkenness trends during the same period. The study sample was composed of 23,169 adolescents aged 15 to 18 years old: 7,103 in 2002, 10,443 in 2006 and 5,623 in 2010. In the three time points of the study, the data were representative of Spanish adolescent students. We used the alcohol consumption questionnaire designed by the international team of the Health Behavior in School-aged Children (HBSC) study. We estimated odds ratios and 95% confidence intervals through logistic regressions. The main results showed a decrease in frequent consumption of wine and liquor from 2002 to 2010. This decrease was maintained after controlling for the variability due to the participants' gender and age. However, an increasing trend was found in drunkenness episodes in the different cohorts of the adolescents under study. The results of this study are of particular importance in the analysis of the effects of the public health policies implemented during this time period. We also found changes in consumption patterns of the various alcoholic drinks, which may constitute key information in the design of new public health policies. Copyright © 2014 SESPAS.

Adolescent low back pain (ALBP) can be considered a signal or precursor of a serious organic disease or telltale sign of future incidence of low back pain in adulthood. Published articles on ALBP in Nigeria are not readily available. The study's objectives were to investigate the prevalence of Adolescent Low Back Pain (ALBP) among secondary school students in Ibadan, Nigeria and the prevalence's association with some socio-demographic variables. Participants were adolescent students from 15 secondary schools in Ibadan. Data was collected using a respondent-administered, validated questionnaire on low back pain in adolescents. Participants (Female: 298; Male: 273) aged 14.23 ±2.27 years (range 10-19) were recruited through multi-stage random sampling. Five hundred and seventy-one (83.97%) of the 680 copies of the questionnaire administered were returned. Data was analysed using mean, standard deviation, frequency, percentages, and Chi-square test with alpha level at 0.05. Lifetime, twelve-month, one-month and point prevalence rates of ALBP were 58.0%, 43.8%, 25.6% and 14.7% respectively. Age at first experience of ALBP was 11.86 ± 2.36 years. Gender was not significantly associated with any rate (p ≥0.317). Age (p ≤ 0.043) and engagement in commercial activities (p ≤ 0.025) were significantly associated with all period prevalence rates while injury to the back was significantly associated with all period prevalence rates except point prevalence (p = 0.087). Adolescent low back pain is common among secondary school students in Ibadan and its prevalence is significantly associated with age and engagement in commercial activities, but not with gender.

Asthma control in adolescents 10 to 11 y after exposure to the World Trade Center disaster

PubMed Central

Gargano, Lisa M.; Thomas, Pauline A.; Stellman, Steven D.

2017-01-01

Background: Little is known about asthma control in adolescents who were exposed to the World Trade Center (WTC) attacks of 11 September 2001 and diagnosed with asthma after 9/11. This report examines asthma and asthma control 10–11 y after 9/11 among exposed adolescents. Methods: The WTC Health Registry adolescent Wave 3 survey (2011–2012) collected data on asthma diagnosed by a physician after 11 September 2001, extent of asthma control based on modified National Asthma Education and Prevention Program criteria, probable mental health conditions, and behavior problems. Parents reported healthcare needs and 9/11-exposures. Logistic regression was used to evaluate associations between asthma and level of asthma control and 9/11-exposure, mental health and behavioral problems, and unmet healthcare needs. Results: Poorly/very poorly controlled asthma was significantly associated with a household income of ≤$75,000 (adjusted odds ratio (AOR): 3.0; 95% confidence interval (CI): 1.1–8.8), having unmet healthcare needs (AOR: 6.2; 95% CI: 1.4–27.1), and screening positive for at least one mental health condition (AOR: 5.0; 95% CI: 1.4–17.7), but not with behavioral problems. The impact of having at least one mental health condition on the level of asthma control was substantially greater in females than in males. Conclusions: Comprehensive care of post-9/11 asthma in adolescents should include management of mental health-related comorbidities. PMID:27656769

Parenting adolescents with cystic fibrosis: the adolescents' and young adults' perspectives.

Bregnballe, Vibeke; Schiøtz, Peter Oluf; Lomborg, Kirsten

2011-01-01

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

Age Got to Do With It? Partner Age Difference, Power, Intimate Partner Violence, and Sexual Risk in Urban Adolescents

2013-01-01

Adolescent girls with older male main partners are at greater risk for adverse sexual health outcomes than other adolescent girls. One explanation for this finding is that low relationship power occurs with partner age difference. Using a cross-sectional, descriptive design, we investigated the effect of partner age difference between an adolescent girl and her male partner on sexual risk behavior through the mediators of sexual relationship power, and physical intimate partner violence (IPV), and psychological IPV severity. We chose Blanc’s framework to guide this study as it depicts the links among demographic, social, economic, relationship, family and community characteristics, and reproductive health outcomes with gender-based relationship power and violence. Urban adolescent girls (N = 155) completed an anonymous computer-assisted self-interview survey to examine partner and relationship factors’ effect on consistent condom use. Our sample had an average age of 16.1 years with a mean partner age of 17.8 years. Partners were predominantly African American (75%), non-Hispanic (74%), and low-income (81%); 24% of participants reported consistent condom use in the last 3 months. Descriptive, correlation, and multiple mediation analyses were conducted. Partner age difference was negatively associated with consistent condom use (−.4292, p < .01); however, the indirect effects through three proposed mediators (relationship power, physical IPV, or psychological IPV severity) were not statistically significant. Further studies are needed to explore alternative rationale explaining the relationship between partner age differences and sexual risk factors within adolescent sexual relationships. Nonetheless, for clinicians and researchers, these findings underscore the heightened risk associated with partner age differences and impact of relationship dynamics on sexual risk behavior.

Childhood and adolescent predictors of late onset criminal careers.

PubMed

Zara, Georgia; Farrington, David P

2009-03-01

This study explores the emergence of a criminal career in adulthood. The main hypothesis tested is that late criminal onset (at age 21 or later) is influenced by early factors that delay antisocial manifestations. The Cambridge Study in Delinquent Development (CSDD) was used to examine early determinants of criminal behavior. 400 Inner London males were followed from ages 8-10 to 48-50, and were classified as follows: 35 late onsetters who were first convicted at age 21 or later, and did not have high self-reported delinquency at ages 10-14 and 15-18; 129 early onsetters first convicted between ages 10 and 20; and 236 unconvicted males. Odds ratios and logistic regression analyses revealed that the best predictors of late onset offenders compared with early onset offenders included nervousness, having few friends at ages 8-10, and not having sexual intercourse by age 18. The best predictors of late onset offenders compared with nonoffenders included teacher-rated anxiousness at ages 12-14 and high neuroticism at age 16. It is concluded that being nervous and withdrawn protected boys against offending in adolescence but that these protective effects tended to wear off after age 21. These findings show that adult offending can be predicted from childhood, and suggest that early intervention might prevent a variety of maladjustment problems and difficulties in adult life.

Neuropsychological Impairments and Age-Related Differences in Children and Adolescents with Fetal Alcohol Spectrum Disorders.

2014-01-01

BackgroundChildren and adolescents with Fetal Alcohol Spectrum Disorders (FASD) exhibit a range of physical, cognitive, behavioral, and/or learning deficits, as wells as poor executive functioning (EF). Children and adolescents with FASD often show greater impairments on complex neuropsychological tasks. However, little is known about age-related differences among children and adolescents with FASD.ObjectivesThe goals of this cross-sectional study were to explore the overall profile of neuropsychological impairments and extended previous reports on age-related differences among children and adolescents with FASD. MethodWe compared 117 children and adolescents diagnosed with an FASD (aged 5-17 years), clinically assessed on a broad range of tests covering 6 neurobehavioral domains. Data from a clinical database was used to generate profiles of neuropsychological impairments for clinically referred children and adolescents evaluated for FASD between 2001 and 2005. ResultsChildren and adolescents were impaired (relative to the norm) on a number of domains that include academic achievement, language, verbal memory, EF, visual-motor integration, and motor abilities. Older participants with FASD (relative to the norm) showed greater difficulty in areas involving EF or processing of complex information than younger participants. ConclusionsThese results suggest that for children and adolescents with FASD impairments in those areas important for independent functioning may become more pronounced with increasing age. However, further longitudinal research is needed to ascertain age changes over time.

Preteen insulin levels interact with caloric intake to predict increases in obesity at ages 18 to 19 years: a 10-year prospective study of black and white girls.

PubMed

Morrison, John A; Glueck, Charles J; Wang, Ping

2010-05-01

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

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

2018-01-01

Suicide in adolescents is the second most common cause of death in this age group and an important public health problem. We examined sociodemographic factors associated with suicide in Swiss adolescents and analysed time trends in youth suicide in the Swiss National Cohort (SNC). The SNC is a longitudinal study of the whole Swiss resident population, based on linkage of census and mortality records. We identified suicides in adolescents aged 10-18 years from 1991 to 2013. A total of 2.396 million adolescents were included and 592 suicides were recorded, corresponding to a rate of 3.7 per 100,000 [95% confidence interval (CI) 3.4-4.0]. Rates increased with age from 0.0 per 100,000 at age 10 years to 14.8 per 100,000 (95% CI 12.6-17.5) at 18 years in boys, and from 0.0 to 5.4 per 100,000 (4.1-7.2) in girls. Being a boy, living in a single parent household, being an only or middle-born child, and living in rural regions were factors associated with a higher rate of suicide. Hanging was the most common method in boys, and railway suicides were most frequent in girls. There was no clear evidence for an increase or decrease over calendar time. We conclude that familial and socioeconomic factors including type of household, birth order and urbanity are associated with youth suicide in Switzerland. These factors should be considered when designing prevention programmes for youth suicide.

Study Objectives: To investigate age-related differences in polysomnographic and sleep electroencephalographic (EEG) measures, considering sex, pubertal stage, ethnicity, and scalp topography in a large group of adolescents in the National Consortium on Alcohol and NeuroDevelopment in Adolescence (NCANDA). Methods: Following an adaptation/clinical screening night, 141 healthy adolescents (12–21 y, 64 girls) had polysomnographic recordings, from which sleep staging and EEG measures were derived. The setting was the SRI International Human Sleep Laboratory and University of Pittsburgh Pediatric Sleep Laboratory. Results: Older age was associated with a lower percentage of N3 sleep, accompanied by higher percentages of N2, N1, and rapid eye movement (REM) sleep. Older boys compared with younger boys had more frequent awakenings and wakefulness after sleep onset, effects that were absent in girls. Delta (0.3–4 Hz) EEG power in nonrapid eye movement NREM sleep was lower in older than younger adolescents at all electrode sites, with steeper slopes of decline over the occipital scalp. EEG power in higher frequency bands was also lower in older adolescents than younger adolescents, with equal effects across electrodes. Percent delta power in the first NREM period was similar across age. African Americans had lower EEG power across frequency bands (delta to sigma) compared with Caucasians. Finally, replacing age with pubertal status in the models showed similar relationships. Conclusions: Substantial differences in sleep architecture and EEG were evident across adolescence in this large group, with sex modifying some relationships. Establishment and follow-up of this cohort allows the investigation of sleep EEG-brain structural relationships and the effect of behaviors, such as alcohol and substance use, on sleep EEG maturation.

Mexico in 2008 was designed as the first place of adolescent pregnancy at the Organization for Economic Cooperation and Development, with specific fertility rate (SFR) for 15-1 9years of age of 64.2/1,000 woman at the same age. Estimate of percentage births and SFR in adolescent population at national, state and municipal level in Mexico in 2008-2012 at the total group of adolescents 10 to 1 9 years old and by subgroups of 10-14 and 15 tol 9 years old, identifying the priority municipalities with adolescence pregnancies. Data bases of certificates of live birth and fetal death with gestational age of 22-45 weeks were joined in 2008-2012. A data base of 1 0'585,032 births in 2008-2012 was obtained, 98.9% were live births and 1.1% was stillbirths. The SFR nationwide for the period 2008-2012 were of the order of 3.l for the group of 10-1 4years, 75.3 for 15-19, 39.6 for the total group of 10-19 years and 66.1 for 20 to 49 years per 1000 women for the same age. In the last decade it has increased teen pregnancy as well as the percentage of births and the fertility rate in this age group, worrying situation for the high risk of biological, psychological and social damage that pregnancy early.

Adolescence is a period of change, which coincides with disease remission in a significant proportion of subjects with childhood asthma. There is incomplete understanding of the changing characteristics underlying different adolescent asthma transitions. We undertook pathophysiological characterization of transitional adolescent asthma phenotypes in a longitudinal birth cohort. The Isle of Wight Birth Cohort (N = 1456) was reviewed at 1, 2, 4, 10 and 18-years. Characterization included questionnaires, skin tests, spirometry, exhaled nitric oxide, bronchial challenge and (in a subset of 100 at 18-years) induced sputum. Asthma groups were "never asthma" (no asthma since birth), "persistent asthma" (asthma at age 10 and 18), "remission asthma" (asthma at age 10 but not at 18) and "adolescent-onset asthma" (asthma at age 18 but not at age 10). Participants whose asthma remitted during adolescence had lower bronchial reactivity (odds ratio (OR) 0.30; CI 0.10 -0.90; p = 0.03) at age 10 plus greater improvement in lung function (forced expiratory flow 25-75% gain: 1.7 L; 1.0-2.9; p = 0.04) compared to persistent asthma by age 18. Male sex (0.3; 0.1-0.7; p < 0.01) and lower acetaminophen use (0.4; 0.2-0.8; p < 0.01) independently favoured asthma remission, when compared to persistent asthma. Asthma remission had a lower total sputum cell count compared to never asthma (31.5 [25-75 centiles] 12.9-40.4) vs. 47.0 (19.5-181.3); p = 0.03). Sputum examination in adolescent-onset asthma showed eosinophilic airway inflammation (3.0%, 0.7-6.6), not seen in persistent asthma (1.0%, 0-3.9), while remission group had the lowest sputum eosinophil count (0.3%, 0-1.4) and lowest eosinophils/neutrophils ratio of 0.0 (Interquartile range: 0.1). Asthma remission during adolescence is associated with lower initial BHR and greater gain in small airways function, while adolescent-onset asthma is primarily eosinophilic.

To develop and evaluate a test activity from which bimanual performance in adolescents with unilateral cerebral palsy (CP) can be observed and scored with the Assisting Hand Assessment (AHA), and to evaluate the construct validity of the AHA test items for the extended age range 18 months to 18 years. A new test activity was developed and evaluated for its ability to elicit bimanual actions in adolescents with (n=20) and without (n=10) unilateral CP. The AHA scores of 126 adolescents (mean age 14y 3mo, SD 2y 6mo; 71 males, 55 females) and 157 children with unilateral CP (mean age 6y 1mo, SD 2y 10mo; 102 males, 55 females) were analysed using the Rasch measurement model. The test activity elicited bimanual actions in 100% of typically developing adolescents and in 96.8% and 57.9% of adolescents with unilateral CP (moderately and severely limited hand function respectively). The scale demonstrated good construct validity; thus the same scoring criteria can be used for the age range studied. The new Assisting Hand Assessment for adolescents (Ad-AHA) activity is valid for use with 13- to 18-year-olds to elicit bimanual performance in adolescents with unilateral CP. The same AHA scoring criteria can be used both for children and for adolescents within the age range 18 months to 18 years. © 2016 The Authors.

Background This review incorporates current research examining alcohol's differential effects on adolescents, adults, and aged populations in both animal and clinical models. Methods The studies presented range from cognitive, behavioral, molecular, and neuroimaging techniques, leading to a more comprehensive understanding of how acute and chronic alcohol use affects the brain throughout the life span. Results Age of life is a significant factor in determining the effect of alcohol on brain functioning. Adolescents and aged populations may be more negatively affected by heavy alcohol use when compared to adults. Conclusions Investigations limiting alcohol effects to a single age group constrains understanding of differential trajectories and outcomes following acute and chronic use. To meaningfully address the sequencing and interaction effects of alcohol and age, the field must incorporate collaborative and integrated research efforts focused on interdisciplinary questions facilitated by engaging basic and applied scientists with expertise in a range of disciplines including alcohol, neurodevelopment, and aging.

Objective Transactional models have been used to explain the relationship between maternal depression and child behavioral problems; however, few studies have examined transactional models for maternal depression and adolescent depression and anxiety. Method Using an autoregressive cross-lagged analysis, we examined the longitudinal association between maternal and adolescent depression to determine the extent to which maternal depression influences adolescent depression and anxiety, and vice versa, over the course of a four-year period. Participants were a community sample of 277 mother-adolescent dyads with offspring aged 10–14 at the first year used in the analyses (43.7% female; 35% African American, 2.9% Hispanic/Latino). Depressive symptoms were assessed using maternal self-report (Center for Epidemiological Studies-Depression Scale [CESD]; Radloff, 1977), and adolescent depression and anxiety were assessed by self-report (Revised Child Anxiety and Depression Scale [RCADS]; Chorpita, Yim, Moffitt, Umemoto, & Francis, 2000). Results The final model, χ2 (14) = 23.74, p= .05; TLI= .97; CFI= .98; RMSEA= .05, indicated that maternal depression was significantly associated with adolescent depression two years later. Interestingly, adolescent depression did not significantly predict maternal depression, and the association between maternal and adolescent depression was not moderated by gender, age, or ethnicity. The association between maternal depression and adolescent anxiety was weaker than that observed for adolescent depression. Conclusions Results suggest that the transaction model of maternal depression may not extend to adolescent depression and anxiety. Furthermore, maternal depression can have an enduring effect on adolescent depression and continued research and clinical monitoring over extended periods of time is warranted. PMID:24702257
