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

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

The objective of the present work is to assess the current breakfast model in different age groups: children between the ages of 6 and 12 years (n = 54); adolescents between the ages of 13 and 17 years (n = 174); and adults, older than 18 years of age (n = 252). For this a questionnaire has been designed that follows the standards of that used for a similar study by our team in 1984 on a sample of 1350 individuals. The modified and amplified questionnaire included open and closed questions about: the omission of breakfast and its causes, foods that are a part of breakfast, the most frequent types and the variations, the role of the second breakfast, the number of fasting hours since dinner, the time spent of breakfast, and the subjective opinion regarding the importance or not of having breakfast. 98.95% answer yes to the question do you have breakfast, but only 9% eats a nutritionally correct breakfast, one defined as that breakfast that supplies 20% of the total energy and includes foods from at least four different groups. All the children included some form of milk product in their breakfast. The adolescents consumed the lowest proportion of cereals (19.4%) and the highest proportion of pastries (24.2%). The percentage of adults who drink coffee with milk (57%) and sugar (37.7%) is significantly higher than that it the other two groups. Bread (37.7%), pastries (28.3%) and cookies (26.1%) are the solid foods eaten most by the adults. The children spend the longest time on breakfast. 35.9% of the sample varies their breakfast, 43.1% never does, and 21% does so sometimes. The average time elapsed between dinner and breakfast is 10.5 +/- 1.2 hours. It is advisable to have a more nutritionally balanced breakfast, including different foods from at least four groups, and including a greater variety in the menus. PMID:9780752

Purpose Spiritual coping is an important determinant of adjustment in youth with chronic illness, but the mechanisms through which it affects outcomes have not been elucidated. It is also unknown whether the role of spiritual coping varies by age or disease group. This study evaluated whether general cognitive attributions explain the effects of spiritual coping on internalizing and externalizing problems in adolescents with cystic fibrosis and diabetes and whether these relationships vary by age or disease group. Methods In this cross-sectional study, adolescents (N=128; M=14.7 yrs) diagnosed with cystic fibrosis or diabetes completed measures of spiritual coping and attributional style. Adolescents and their caregivers reported on adolescents’ internalizing and externalizing problems. Results Overall, positive spiritual coping was associated with fewer internalizing and externalizing problems. Negative spiritual coping was related to more externalizing problems, and for adolescents with cystic fibrosis only, also internalizing problems. Optimistic attributions mediated the effects of positive spiritual coping among adolescents with diabetes. The results did not vary by age. Conclusions An optimistic attribution style may help explain the effects of positive, but not negative, spiritual coping on adjustment of youth with diabetes. Youth with progressive, life-threatening illnesses, such as cystic fibrosis, may be more vulnerable to the harmful effects of negative spiritual coping. Future research should examine if addressing spiritual concerns and promoting optimistic attributions improves adolescents’ emotional and behavioral functioning. PMID:23298988

Developing motor competence and physical fitness can affect the maintenance of a sufficient level of physical activity in children and adolescents. This study assesses the relationship between motor competence and physical fitness from childhood through early adolescence. A cross-sectional sample of 194 participants from 4 to 16 years old were divided into three groups; 4-6 yr. (n=42, M age=5.2, SD 0.6), 11-12 yr. (n=58, M age=12.4, SD=0.3), and 15-16 yr. (n=94, M age=15.9, SD=0.4). To assess motor competence, each child completed the Movement Assessment Battery for Children (MABC). To measure physical fitness, three tasks (strength, speed, and endurance) were selected from the Test of Physical Fitness (TPF). To analyze the significance of the difference between the correlation coefficient in the three age groups (samples) (4-6, 11-12, and 15-16 yr.), Fischer r-to-z transformation was used. The correlation (Pearson's) between motor competence and physical fitness in the age groups was statistically higher for the youngest age groups (4-6 and 11-12 yr.) and the adolescent group (age 15-16). The differences between the two youngest age groups were not statistically significant. The results demonstrate that the correlation between motor competence and physical fitness decreases with age.

Aims: Recent studies with animal models showed that the stimulant and sedative effects of alcohol change during the adolescent period. In humans, the stimulant effects of ethanol are most often indirectly recorded through the measurement of explicit and implicit alcohol effect expectancies. However, it is unknown how such implicit and explicit expectancies evolve with age in humans during adolescence. Methods: Adolescent (13–16 year old), young adult (17–18 year old), and adult (35–55 year old) participants were recruited. On the basis of their score on the Alcohol Use Disorder Identification Test (AUDIT), they were classified as non-problem (AUDIT ≤ 7) or problem (AUDIT ≥ 11) drinkers. The participants completed the Alcohol Expectancy Questionnaire (AEQ) and performed two unipolar Implicit Association Test (IAT) to assess implicit associations between alcohol and the concepts of “stimulation” and “sedation”. Results: Problem drinkers from the three age groups reported significantly higher positive alcohol expectancies than non-problem drinkers on all AEQ subscales. Positive alcohol explicit expectancies also gradually decreased with age, with adolescent problem drinkers reporting especially high positive expectancies. This effect was statistically significant for all positive expectancies, with the exception of relaxation expectancies that were only close to statistical significance. In contrast, stimulation and sedation alcohol implicit associations were not significantly different between problem and non-problem drinkers and did not change with age. Conclusion: These results indicate that explicit positive alcohol effect expectancies predict current alcohol consumption levels, especially in adolescents. Positive alcohol expectancies also gradually decrease with age in the three cross-sectional groups of adolescents, young adults, and adults. This effect might be related to changes in the physiological response to alcohol. PMID:26635680

The relationships of adolescent school-related deviant behaviour and victimization with psychological distress: testing a general model of the mediational role of parents and teachers across groups of gender and age.
Herrero, Juan; Estévez, Estefanía; Musitu, Gonzalo
Deviant behaviour and victimization at school have been consistently related to poor psychological adjustment in adolescents. This research explores the mediating role that parents and teachers have in adolescent psychological distress in 973 Spanish students aged 11-16 years old. Structural equation analyses results showed that adolescent deviant behaviour and victimization were positively related to psychological distress as seen by the total effects. However, while victimization was directly related to psychological distress, the association of deviant behaviour and psychological distress was mediated by adolescent-parent communication and adolescent-teacher relationships. Multigroup analyses showed that relationships among variables were not significantly different for groups of age and gender. PMID:16263163

Underage drinking is among the most serious of public health problems facing adolescents in the United States. Recent concerns have centered on young women, reflected in media reports and arrest statistics on their increasing problematic alcohol use. This study rigorously examined whether girls' alcohol use rose by applying time series methods to both arrest data, Uniform Crime Reports, and self-report data from Monitoring the Future, a nationally representative long-term survey gathered independently of crime control agents. All self-reported drinking behaviors across all age groups show declining or unchanged female rates and no significant change in the gender gap, while the official source displays a steady narrowing gender gap and some increase of female arrest rates for liquor law violations. Results indicate that social control measures applied to underage drinking have shifted to target young women's drinking patterns, but their drinking has not become more widespread/problematic. Girls' increased alcohol use and abuse is a socially constructed problem, rather than the result of normalization of drinking or more strain in girls' lives. Future underage drinking policies and practices that apply legal intervention strategies to less chronic adolescent drinking behaviors will increase the visibility of girls' drinking. PMID:20596818

The indications for a corrective surgical procedure for the complex 3-dimensional deformations of the spine collectively known under the term scoliosis, essentially depend on knowledge of the underlying etiology, the time of initial diagnosis in relation to the growth curve of the child and on considerations about the general operability of the patient. An early onset of scoliosis in childhood under defined diagnostic criteria is usually associated with a fast progression of spinal curvature and requires early surgical intervention during the growth period, while scoliosis in adolescence often allows a delayed surgical intervention until all conservative means have been taken into consideration. Corrective measures in the growing spine require procedures and adjustable hardware which can be adapted to vertebral and thoracic growth and thus anticipate the threat of pulmonary insufficiency due to postural and spinal collapse. Towards the end of puberty when spinal growth slowly comes to an end, corrective spinal fusion procedures are considered in those cases of early and late onset scoliosis, where curvature progression is likely to occur.

The current study examined the association of callous-unemotional (CU) traits with group offending (i.e., committing a crime with others; gang involvement) and with the role that the offender may play in a group offense (e.g., being the leader). This analysis was conducted in an ethnically and racially diverse sample (N = 1,216) of justice-involved adolescents (ages 13 to 17) from 3 different sites. CU traits were associated with a greater likelihood of the adolescent offending in groups and being in a gang. Importantly, both associations remained significant after controlling for the adolescent's age, level of intelligence, race and ethnicity, and level of impulse control. The association of CU traits with gang membership also remained significant after controlling for the adolescent's history of delinquent behavior. Further, CU traits were associated with several measures of taking a leadership role in group crimes. CU traits were also associated with greater levels of planning in the group offense for which the adolescent was arrested, although this was moderated by the adolescent's race and was not found in Black youth. These results highlight the importance of CU traits for understanding the group process involved in delinquent acts committed by adolescents. They also underscore the importance of enhancing the effectiveness of treatments for these traits in order to reduce juvenile delinquency. PMID:25689410

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

In the present study, we examined demographic differences in time attitudes in a sample of 293 adolescents. Time attitudes were measured using the Adolescent Time Attitude Scale (Mello & Worrell, 2007; Worrell, Mello, & Buhl, 2011), which assesses positive and negative attitudes toward the past, the present, and the future. Generally, African Americans and Asian Americans reported higher scores for negative time attitudes and lower scores for positive time attitudes than European Americans and Latinos, with medium sizes. Adolescents in the low socioeconomic status group reported a less favorable evaluation of their past than middle and high SES peers, but there were no meaningful differences in time attitudes by gender. Findings indicate that middle SES adolescents, high school juniors and seniors, Latinos, and European Americans had higher representation in positive time attitude clusters (i.e., Positives and Balanced) than high SES adolescents, high school freshmen and sophomores, and African Americans.

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. PMID:26613696

There is growing support for the large-scale implementation of parenting programs for the prevention of child behavior disorders and child maltreatment in younger children. However, there is only limited evidence on the efficacy of parenting programs in modifying risk and protective factors relating to adolescent behavior problems. This study examined the efficacy of Group Teen Triple P (GTTP), an eight-session parenting program specifically designed for parents of young adolescents. Seventy-two families with adolescents aged between 12 and 15 years were randomly assigned to either GTTP (n = 35) or a care as usual (CAU) control condition (n = 37). Compared to CAU parents, parents who received GTTP reported significant improvements in parenting practices, parenting confidence, the quality of family relationships, and fewer adolescent problem behaviors at post-intervention. Several of the parent-reported effects were corroborated by reports from adolescents, including decreases in parent-adolescent conflict and increases in parental monitoring. Adolescents whose parents participated in GTTP also reported significantly fewer behavioral problems than adolescents in the CAU condition. Many of these improvements were maintained at 6-month follow-up. PMID:25373684

[Purpose] Poor posture in children and adolescents is a well-known problem. Therefore, early detection of incorrect posture is important. Photometric posture analysis is a cost-efficient and easy method, but needs reliable reference values. As children’s posture changes as they grow, the assessment needs to be age-specific. This study aimed to investigate the development of both one-dimensional posture parameter (body inclination angle) and complex parameter (posture index) in different age groups (childhood to adolescence). [Subjects and Methods] The participants were 372 symptom-free children and adolescents (140 girls and 232 boys aged 6–17). Images of their habitual posture were obtained in the sagittal plane. High-contrast marker points and marker spheres were placed on anatomical landmarks. Based on the marker points, the body inclination angle (INC) and posture index (PI) were calculated using the Corpus concepts software. [Results] The INC angle significantly increased with age. The PI did not change significantly among the age groups. No significant differences between the corresponding age groups were found for PI and INC for both sexes. [Conclusion] When evaluating posture using the body inclination angle, the age of the subject needs to be considered. Posture assessment with an age-independent parameter may be more suitable.

More knowledge is needed about the etiology and treatment needs of adolescent sex offenders. The current study compared adolescents who had offended against children (defined as below the age of 12 and at least 5 years younger than the adolescent), adolescents who have offended against peers or adults, and adolescents who had victims in both age groups. Based on Seto and Lalumière's meta-analytic findings, participants were compared on theoretically derived factors, including childhood sexual abuse, atypical sexual interests, sexual experience, social competence, psychiatric history, and general delinquency factors (past criminal history, substance abuse history, and offense characteristics). The study sample consisted of 162 court-referred male adolescent sexual offenders aged 12 to 17 years. Of the six identified domains, groups significantly differed on five of them; the exceptions were variables reflecting social competence. The results further support the validity of distinguishing adolescent sex offenders by victim age. PMID:24906363

Religious group identification is an important but understudied social identity. The present study investigates religious group identification among adolescents of different faiths (Hindu, Muslim, Christian) living in multicultural Mauritius. It further explores how religious and national group identities come together among religious majority and minority adolescents. For three age groups (11 to 19 years, N = 2152) we examined the strength of adolescents' religious and national group identification, the associations between these two identities, and the relationships to global self-esteem. Across age and religious group, participants reported stronger identification with their religious group than with the nation. Identification with both categories declined with age, with the exception of Muslims, whose strong religious identification was found across adolescence. The association between religious and national identification was positive, albeit stronger for the majority group of Hindus and for early adolescents. We examined the manner in which religious and national identities come together using a direct self-identification measure and by combining the separate continuous measures of identification. Four distinct clusters of identification (predominant religious identifiers, dual identifiers, neutrals, and separate individuals) that were differently associated with global self-esteem were found. Dual identifiers reported the highest level of global self-esteem. The clusters of identification did not fully correspond to the findings for the direct self-identification measure. The results are discussed in terms of the meaning of dual identity and the positive manner in which adolescents can manage their multiple identities while taking into account the ideological framework in which those identities are played out.

Focal theory is considered as a framework for looking at psychosocial and leisure transitions in middle and later adolescence. Although these transitions are examined from a different perspective in the present study, by utilising cross-sectional survey data from a representative sample of three age groups of young Scots (13-14, 15-16 and 17-18 year-olds), the results confirm and extend the general age-trends in relational issues and leisure involvement reported in original studies. Within this overall picture, few gender differences are found in age-related relational transitions, but gender differences are apparent in shifting focuses of leisure involvement with age. Further, the findings suggest a linkage between relational issues in adolescence and leisure contexts, where psychosocial processes are seen to be associated with contextual changes in young people's lives. Focal theory has been criticised for a failure to take true account of the social circumstances, constraints and contexts affecting adolescent development, but in the present study surprisingly few differences are found with respect to the young person's social class of family background, for example, with age-trends in developmental transitions similar for all social groups. By contrast, in later adolescence aspects of the young person's own socio-economic position, rather than that of their family background, are clearly linked to both relational issues and leisure involvement, for example, creating a disrupting effect on those young people who are currently unemployed or non-employed at this age.

We used a longitudinal data set to evaluate an observational assessment of adolescent competence within a group context. Participants were 40 (21 males, 19 females) ethnically diverse children who had earlier been observed in summer camp (age 10) and preschool (age 4 1/2), as well as in infancy. A revealed differences task was videotaped as part of an intensive weekend camp reunion at ages 15 to 16. Raters, blind to the adolescents' developmental histories, coded each adolescent on the following behavioral rating scales: enjoyment of the task, involvement, leadership, self-confidence in the task, and global social competence. Both concurrent validity (strong correlations with independent camp reunion counselor ratings and peer sociometric measures) and clear associations with antecedent measures of peer competence in preschool and middle childhood were demonstrated. A pattern of correlations revealed considerable discriminate validity. Neither IQ nor socioeconomic status accounted for these associations. Overall, the results confirm the power of a developmentally appropriate, taxing, behaviorally based assessment of group functioning as a measure of competence in adolescence. PMID:11016565

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. PMID:24431258

Qualitative research, based on the Theory of Social Representations, which aimed to apprehend the social representations of teenagers in a public school and a private on ageing, and to compare them between these two groups. Participants were 60 adolescents, 30 from the private school and 30 from the public school, who responded to semi-structured interviews in the period May-June 2012. The collected data were subjected to content analysis techniques, from which emerged three categories, namely: representations of ageing, the treatment of the elderly, and the recognition of oneself as a subject in the aging process. The adolescents' social representations have showed negative and positive aspects in relation to old age, marked by the influence of socio-cultural aspects. PMID:25271586

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.

Underage drinking is among the most serious of public health problems facing adolescents in the United States. Recent concerns have centered on young women, reflected in media reports and arrest statistics on their increasing problematic alcohol use. This study rigorously examined whether girls' alcohol use rose by applying time series methods to…
Background Compared to other European countries, the Netherlands score among the highest of binge drinking rates of 16 to 18 year old adolescents. Dutch adolescents aged 16 are legally allowed to buy and consume low strength alcoholic beverages. This study focused on determinants of binge drinking in such a permissive environment from the perspectives of adolescents and parents. Methods Focus group interviews were conducted with adolescents aged 16 to 18 (N = 83), and parents of adolescents from this age group (N = 24). Data was analysed using thematic analyses methods. Results Most reasons adolescents mentioned for drinking were to relax, increase a good mood and to be social. Also peers around them influenced and increased adolescents’ drinking. Comparing adolescents and parental statements about their perspectives how alcohol use is handled and accepted by the parents we found that generally, those perspectives match. Parents as well as adolescents stated that alcohol use is accepted by parents. However, when looking at essential details, like the acceptable amounts that children may consume, the perspectives differ enormously. Adolescents think their parents accept any amount of drinking as long as they do not get drunk, whereas parents reported acceptable limits of 1 or 2 glasses every two weeks. Parents further indicated that they felt unsupported by the Dutch policies and regulations of alcohol use. Most of them were in favour of an increase of the legal purchasing age to 18 years. Conclusions Parents and adolescents should both be targeted in interventions to reduce alcohol use among adolescents. In particular, communication between parents and children should be improved, in order to avoid misconceptions about acceptable alcohol use. Further, adolescents should be supported to handle difficult social situations with peers where they feel obliged to drink. Additionally, revisions of policies towards a less permissive standpoint are advised to

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

Objectives: This study was designed to evaluate bone mineral density (BMD) in healthy female Brazilian adolescents in five groups looking at chronological age, bone age, and pubertal breast stage, and determining BMD behavior for each classification. Methods: Seventy-two healthy female adolescents aged between 10 to 20 incomplete years were divided into five groups and evaluated for calcium intake, weight, height, body mass index (BMI), pubertal breast stage, bone age, and BMD. Bone mass was measured by bone densitometry (DXA) in lumbar spine and proximal femur regions, and the total body. BMI was estimated by Quetelet index. Breast development was assessed by Tanner’s criteria and skeletal maturity by bone age. BMD comparison according to chronologic and bone age, and breast development were analyzed by Anova, with Scheffe’s test used to find significant differences between groups at P≤0.05. Results: BMD (g·cm-2) increased in all studied regions as age advanced, indicating differences from the ages of 13 to 14 years. This group differed to the 10 and 11 to 12 years old groups for lumbar spine BMD (0.865±0.127 vs 0.672±0.082 and 0.689±0.083, respectively) and in girls at pubertal development stage B3, lumbar spine BMD differed from B5 (0.709±0.073 vs 0.936±0.130) and whole body BMD differed from B4 and B5 (0.867±0.056 vs 0.977±0.086 and 1.040±0.080, respectively). Conclusion: Bone mineralization increased in the B3 breast maturity group, and the critical years for bone mass acquisition were between 13 and 14 years of age for all sites evaluated by densitometry.

The number of people surviving until old age has been increasing worldwide. Reduction in fertility and mortality have resulted in increasing survival of populations to later life. This study examines the mortality trends among the three main ethnic groups in Malaysia, namely; the Malays, Chinese and Indians for four important age groups (adolescents, adults, middle age and elderly) for both gender. Since the data on mortality rates in Malaysia is only available in age groups such as 1-5, 5-9, 10-14, 15-19 and so on, hence some distribution or interpolation method was essential to expand it to the individual ages. In the study, the Heligman and Pollard model will be used to expand the mortality rates from the age groups to the individual ages. It was found that decreasing trend in all age groups and ethnic groups. Female mortality is significantly lower than male mortality, and the difference may be increasing. Also the mortality rates for females are different than that for males in all ethnic groups, and the difference is generally increasing until it reaches its peak at the oldest age category. Due to the decreasing trend of mortality rates, the government needs to plan for health program to support more elderly people in the coming years.

Aim The aim of this study was to investigate long-term cognitive outcome in a cohort of 18-year-olds born preterm and previously assessed at the age of 5.5. Methods We tested 134 adolescents born preterm with a very low birthweight of <1500 g and 94 term-born controls with a comprehensive cognitive battery at 18 years of age. The cohort was subdivided into 73 extremely preterm, 42 very preterm and 19 moderately preterm infants with gestational ages of 23–27, 28–31 and 32–36 weeks, respectively. The moderately preterm group was dominated by adolescents born small for gestational age. Results Very preterm adolescents performed on a par with term-born controls. In contrast, extremely preterm adolescents displayed inferior results on all cognitive tests, more so if they had suffered neonatal complications. Moderately preterm adolescents scored lower than very preterm and full-term born adolescents, particularly on complex cognitive tasks. Conclusion Adolescents born at 28 weeks of gestation or later, with appropriate birthweight and no perinatal complications, functioned like term-born peers at 18 years of age. Extremely preterm birth per se posed a risk for long-term cognitive deficits, particularly executive deficits. Adolescents born moderately preterm but small for gestational age were at risk of general cognitive deficits. PMID:25394225

Adolescents are considered a high nutritional risk group because their nutritional needs are increased with respect to other age groups, and because this period of life coincides with changes in life style that affect, often negatively, their eating habits. Our overall goal is to study the usual eating pattern of Valencian adolescents together with their drink and tobacco consumption, but the first stage focuses on setting up, validating and correcting methods to be applied. The present study was therefore carried out in a sample composed of 64 adolescents, ranging from 16 to 20 years of age. A self administered survey developed in our Department was used to explore their food preferences, eating habits, smoking habits and alcohol and coffee intake. The following results were obtained: The number of daily meals was of 3.7 +/- 0.9. The 91% takes the breakfast daily (milk with cereals or sweet rolls) and the majority of the students eat a second mid-morning breakfast. Lunch is of the traditional type, consisting of two courses. The first is rice or pasta, followed by meat, fish or eggs usually accompanied by a side dish or salad. Fresh fruit is the dessert eaten, almost daily by the majority of the sample. The most usual drink is water. The 70% of the sample have one supplementary afternoon intake "merienda". All of the surveyed people like fruits, pasta and chicken meat. While, liver and legumes are disliked by the majority. The intakes of soft drinks, snacks, alcohol, coffee and tobacco are moderate, being, all these products mainly consumed during the weekend. The mean diet offers an excess of proteins and saturated fat, while complex carbohydrates and dietetic fiber are scarce. Nutritional intakes of iron, magnesium and zinc in girls, and magnesium, folates and vitamin A in boys are estimated insufficient to fulfil their needs. PMID:10670259

Children with epilepsy are at risk for numerous psychological and social challenges. We hypothesized that art therapy focus groups would enhance the self-image of children and adolescents with epilepsy. Sixteen children with epilepsy, ages 7-18 years, were recruited from pediatric neurology clinics at the University of Wisconsin to participate in four art therapy sessions. Pre-group assessments included psychological screens (Piers-Harris Children's Self-Concept Scale; Childhood Attitude Toward Illness Scale; Impact of Childhood Neurologic Disability Scale) and art therapy instruments (Formal Elements Art Therapy Scale; Seizure Drawing Task; Levick Emotional and Cognitive Art Therapy Assessment). Developmental levels of drawings were significantly below age-expected standards. Following completion of focus groups, a repeat Childhood Attitude Toward Illness Scale showed no differences between pre- and post-test scores on any measure of this scale. However, subjects and parents were uniformly positive about their group experiences, suggesting a qualitative benefit from participation in art therapy focus groups. PMID:22554978

PURPOSE The standard of care for adolescent patients with Hodgkin's lymphoma (HL) is undefined, particularly the choice between pediatric and adult protocols. Thus, we compared risk factors and outcome of adolescents and young adults treated within study protocols of the German Hodgkin Study Group (GHSG). PATIENTS AND METHODS Three thousand seven hundred eighty-five patients treated within the GHSG studies HD4 to HD9 were analyzed; 557 patients were adolescents age 15 to 20 years, and 3,228 patients were young adults age 21 to 45 years. Results Large mediastinal mass and involvement of three or more lymph node areas were more frequent in adolescents (P < .001). The incidence of other risk factors did not differ significantly between age groups. With a median observation time of 81 months for freedom from treatment failure (FFTF) and 85 months for overall survival (OS), log-rank test showed no significant differences between age groups regarding FFTF (P = .305) and a superior OS (P = .008) for adolescents. Six-year estimates for FFTF and OS were 80% and 94%, respectively, for adolescents and 80% and 91%, respectively, for young adults. After adjustment for other predictive factors, Cox regression analysis revealed age as a significant predictor for OS (P = .004), with a higher mortality risk for young adults. Secondary malignancies were more common in young adults (P = .037). CONCLUSION Outcome of adolescent and young adult patients treated within GHSG study protocols is comparable. These data suggest that adult treatment protocols exhibit a safe and effective treatment option for adolescent patients with HL. However, longer follow-up, including assessment of late toxicity, is necessary for final conclusions. PMID:19901121
This article summarizes the activities at the ESCAP Population Division Expert Group Meeting on Adolescents that was held during September-October 1997 in Bangkok, Thailand. The meeting was a follow-up to the 1994 International Conference on Population and Development (ICPD). The meeting considered 1) the ICPD recommendations; 2) the recommendations contained in the Jakarta Plan of Action on Human Resource Development; and 3) the Proposals for Action on Human Resources Development for Youth in Asia and the Pacific. Participants included about 25 people from Australia, Bangladesh, China, India, Indonesia, Philippines, Sri Lanka, and Thailand. The conference relied on 8 invited experts, two resource persons, advisors from the UNFPA Country Support Team for East and Southeast Asia, and representatives of UNFPA, the Population Council, and the East-West Center. A concern was the declining age of menarche of girls in the ESCAP region and the increasing age of marriage. During the time of menarche and marriage, girls are migrating and moving away from their family and community in rural areas. Family structure and relationships are changing. Increases are observed in adolescent premarital sexual activity, the incidence of sexually transmitted diseases, substance abuse, teenage pregnancy, and abortion. The mass media and information technologies have both a positive and a negative influence on adolescents. Parent-child communication exchanges and teacher-student exchanges are "less than ideal." Old traditions and practices change slower than people change. Boys and girls are affected differently by the sociocultural and economic environment. The societal norms set expectations for behavior that may conflict with individual beliefs and practices. Changes brought by globalization and rapid economic growth provide greater opportunity for young girls and women to obtain employment and autonomy. PMID:12293003

This review addresses peer group influences on adolescent smoking with a particular focus on recently published longitudinal studies that have investigated the topic. Specifically, we examine the theoretical explanations for how social influence works with respect to adolescent smoking, discuss the association between peer and adolescent smoking; consider socialization and selection processes with respect to smoking; investigate the relative influence of best friends, close friends, and crowd affiliations; and examine parenting behaviors that could buffer the effects of peer influence. Our review indicates the following with respect to adolescent smoking: (1) substantial peer group homogeneity of smoking behavior; (2) support for both socialization and selection effects, although evidence is somewhat stronger for selection; (3) an interactive influence of best friends, peer groups and crowd affiliation; and (4) an indirect protective effect of positive parenting practices against the uptake of adolescent smoking. We conclude with implications for research and prevention programs. PMID:20614184

Contrary to common stereotypes, loneliness is not restricted to old age but can occur at any life stage. In this study, we used data from a large, nationally representative German study (N = 16,132) to describe and explain age differences in loneliness from late adolescence to oldest old age. The age distribution of loneliness followed a complex nonlinear trajectory, with elevated loneliness levels among young adults and among the oldest old. The late-life increase in loneliness could be explained by lower income levels, higher prevalence of functional limitations, and higher proportion of singles in this age group. Consistent with an age-normative perspective, the association of income, relationship status, household size, and work status with loneliness differed between different age groups. In contrast, indicators of the quantity of social relationships (social engagement, number of friends, contact frequency) were universally associated with loneliness regardless of age. Overall, these findings show that sources of loneliness in older adults are well understood. Future research should focus on understanding the specific sources of loneliness in middle-aged adults.

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.

Introduction Maximum bite force (MBF) is the maximum force performed by the subject on the fragmentation of food, directly related with the mastication and determined by many factors. Objective Analyze the MBF of subjects according to age groups. Methods One hundred individuals from the city of São Paulo were equally divided according to age groups and gender. Each individual submitted to a myotherapy evaluation composed of anthropometric measurements of height and weight to obtain body mass index (BMI), using a tape and a digital scale (Magna, G-life, São Paulo), and a dental condition and maximum bite force evaluation, using a digital dynamometer model DDK/M (Kratos, São Paulo, Brazil), on Newton scale. The dental and bite force evaluations were monitored by a professional from the area. Analysis of variance was used with MBF as a dependent variable, age group and gender as random factors, and BMI as a control variable. Results Till the end of adolescence, it was possible to observe a decrease in MBF in both sexes, with the male force greater than the female force. In young adults, the female force became greater the males, then decreased in adulthood. There was no correlation between MBF and BMI. Conclusion There are MBF variations that characterizes the human development stages, according to age groups. PMID:25992105

Aim The aim of this study was to evaluate the use of the London Atlas of Human Tooth Development and Eruption for age estimation in Saudi Arabian children and adolescents (aged 2–20 years), for forensic odontology application. Materials and methods This cross-sectional survey analyzed orthopantomograms (OPGs) of the complete dentition (including root development) to estimate the deviation from chronological age. Each OPG was de-identified and analyzed individually and classified into age-groups by the lead author, using the methods of the Atlas of Tooth Development. Results OPGs from a total of 252 patients [110 (44%) males, 142 (56%) females] aged 2–20 years (24–240 months) were examined in this study. The average estimated and chronological ages of subjects differed significantly p < 0.001 (143 ± 55.4 vs. 145 ± 57.9 months). Most (65.5%) estimates were within 12 months of subjects’ chronological ages; 19% overestimated and 15.5% underestimated age by >12 months. Conclusion This study, conducted in a sub-population of different origin than the UK sample used for the development of the London Atlas, identified variation in age estimates that may have significant impacts on results. The establishment of a composite international repository of atlas-based data for diverse ethnic sub-populations would be of great value to clinicians across the globe. PMID:26236126

Background The protection, which some BCG vaccines could confer against the development of tuberculosis (TB) in childhood, might be indirectly reflected by the subsequent development of BCG immune response. The objectives of the study were to examine effectiveness and possible differences of post-vaccination reaction to a lyophilized BCG at different age groups and to evaluate its protection against TB in a decade's period. Methods We studied the post-vaccination PPD-skin reaction and scar formation at three different school levels, corresponding to ages of 6, 12 and 15 years old, vaccinated by a lyophilized BCG vaccine (Pasteur Institute), currently used in our country. During a 10-year follow up the reported TB cases in vaccinated and non-vaccinated adolescences up to 24-years old were analyzed and compared to the number of cumulative cases observed in the adult population of two neighboring territories (vaccinated and non-vaccinated). Results and Discussion There was a significant correlation (r2 = 0.87, p < 0.0001) between tuberculin induration and scar formation. There was no statistically significant difference between the three age groups (6, 12, and 15 year-old, respectively) in regard to the diameter of tuberculin induration or scar formation. Although 34% of 10-year later indurations were unpredictably related to the initial ones (increased or decreased), they were significantly correlated (r2 = 0.45, p = 0.009). The relative percentage of TB for the 14–24 years-age group to the adult studied population was significantly lower among the immunized children compared to the non-immunized population of the same age group (17/77, 22% vs. 71/101, 70%, p < .0001). Conclusion Our data suggest that the lyophilized BCG vaccine used for BCG programs at different age groups is equally effective and may confer satisfactory protection against tuberculosis in puberty.

This study examined age-related changes in a specific aspect of adolescent decision-making, namely the preference for future versus immediate outcomes. A sample of 622 Dutch adolescents aged 12–17 years completed a temporal discounting task. Participants were asked to choose between a delayed reward of €50 or an immediate reward of lower value. The delay interval was varied in three blocks (1 week, 1 month, 6 months). Results showed that preferences for large delayed rewards over smaller immediate rewards increased with age: late adolescents made more long-term decisions than early adolescents. This change was related to educational track. In the lower educational track, an age-related decrease in discounting was found for all three delay intervals. In the higher educational track this decrease only occurred for the 6 month delay interval. However, across all delay intervals enrolment in a higher level educational track was associated with an increased preference for long-term rewards. These results suggest that late adolescents are less susceptible than early adolescents to the competing presence of an immediate reward when making long-term decisions, a skill which becomes increasingly important as they transition into adulthood.

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

This study examined (1) emotional versus cognitive developmental trajectories and (2) the influence of age-extrinsic factors (i.e., sex and puberty). Using a cross-sectional design, adolescents (N = 252) divided into four age-groups (ages 13, 15, 17, 19) performed two versions of a mentalizing task, about emotions and actions, as well as the Tower task. First, performance on all tasks improved linearly into late adolescence (age 19). Thus no differential trajectories were found for emotional versus cognitive development. Second, girls outperformed boys in mentalizing speed regarding both emotions and actions. In boys, a later pubertal phase was associated with increased mentalizing speed after controlling for age-group. PMID:20721775

Adolescents' attitudes toward disadvantaged groups are surprisingly understudied. What we know from these few studies is that adolescents' attitudes tend to become more favorable over time and that adolescent girls display more favorable attitudes than do adolescent boys. However, researchers have not offered explanations for why these effects occur. We proposed that changes in social-cognitive abilities that accompany adolescent development increase perspective taking and that the increased perspective taking facilitates more favorable attitudes toward disadvantaged groups. Because girls develop social-cognitive abilities earlier than boys, girls should show greater perspective taking and thus more positive attitudes toward disadvantaged groups than should boys. Importantly, we propose that these more positive attitudes are explained better by perspective taking than by gender. Participants were late adolescents (n = 803, 53.3 % female, ages 15-19) from high schools in north-central Florida (United States) participating in an ongoing, multi-wave study. Participants completed a measure of perspective-taking and reported their attitudes toward three disadvantaged groups (Black, gay, and poor people) during their third year of high school and, again, 6 months later during their fourth year of high school. Our findings provided strong support for our theorizing. Girls generally reported warmer attitudes than did boys toward disadvantaged groups, with the gender differences in warmth tending to diminish across time. Similarly, girls were higher than boys in perspective-taking abilities at both time points, although boys increased over time whereas girls did not. Crucially, perspective taking mediated observed gender differences in attitudes, suggesting that perspective taking is a mechanism for improving attitudes toward disadvantaged groups during late adolescence.

A properly interpreted electrocardiogram (ECG) provides important information and is an inexpensive and easy test to perform. It continues to be the method of choice for the diagnosis of arrhythmias. Although the principles of cardiac electrophysiology are the same, there are anatomical and physiological age-dependent changes which produce specific alterations in the paediatric ECG, and which may be misinterpreted as pathological. The intention of this article is to address in a systematic way the most relevant aspects of the paediatric ECG, to propose a possible reading scheme of the ECG and to review the electrocardiograph tracings most frequently found in the paediatric age group.

The aim of the study was to estimate dietary intake of lycopene by the group of 100 women, from Central Poland, in different age <30 years, 30-50 years, >50 years (mean age 49 +/- 16 years) and main sources of lycopene. The study was carried out in the year 2006 (June-July) with the use of 4-day dietary food records. The lowest intake of lycopene was noted in the youngest group--4.17 mg/person/day, the highest intake in the oldest group--4.88 mg/person/day. The main sources of lycopene in food rations were tomato products (50.6%) and fresh tomatoes (43.5%). Tropical fruit delivered 5.2% of lycopene, other fruit and vegetable juices only 0.7%. Intakes of products, sources of lycopene, depended on age of women and were statistically significant in case of tomato, watermelon, pink grapefruit, and tomato products: ketchup, liquid tomato sauces, liquid tomato soups, tomato juice.

Purpose. To identify and study causes of vitreous hemorrhage (VH) in pediatric age group and to investigate factors predicting visual and anatomical outcomes. Procedure. A retrospective review of patients aged 16 years or less with the diagnosis of vitreous hemorrhage from January 2005 until December 2010. Results. A total number of 230 patients (240 eyes) were identified. Traumatic vitreous hemorrhage accounted for 82.5%. In cases of accidental trauma, final visual acuity of 20/200 was significantly associated with visual acuity of ≥20/200 at presentation and the absence of retinal detachment at last follow-up. Patients with nontraumatic vitreous hemorrhage were significantly younger with higher rates of enucleation/evisceration/exenteration and retinal detachment at last follow-up compared to traumatic cases. Conclusion. Trauma is the most common cause of VH in pediatric age group. In this group, initial visual acuity was the most important predictor for visual outcome, and the presence of retinal detachment is a negative predictor for final good visual outcome. The outcome is significantly worse in nontraumatic cases compared to traumatic cases. PMID:25505975

The goals of this study were to examine intra-group and inter-group assertiveness among adolescents, and to compare these two domains of assertiveness between cultural groups in Israel. Measures of intra-group and inter-group assertiveness were developed, and questionnaires were administrated to 441 immigrants from the Former Soviet Union (FSU), 242 immigrants from Ethiopia and 333 non-immigrants. Compared to non-immigrants, FSU and Ethiopian immigrants' inter-group assertiveness was lower. Girls reported higher levels of inter-group assertiveness than boys. Each of the immigrant groups rates itself as equally assertive as the non-immigrant group and more assertive than the other immigrant group. Also, a difference between inter-group and intra-group assertiveness was found among the FSU immigrants. It is argued that adolescents' assertiveness following cultural transition is associated with socio-cultural context, and the implications of this conclusion are discussed. PMID:22209662

With the recent growth of functional magnetic resonance imaging (fMRI), scientists across a range of disciplines are comparing neural activity between groups of interest, such as healthy controls and clinical patients, children and young adults and younger and older adults. In this edition of Tools of the Trade, we will discuss why great caution must be taken when making group comparisons in studies using fMRI. Although many methodological contributions have been made in recent years, the suggestions for overcoming common issues are too often overlooked. This review focuses primarily on neuroimaging studies of healthy aging, but many of the issues raised apply to other group designs as well. PMID:18846241

Analyzed 195 human figure drawings (HFDs) of adolescents, young adults, and middle-aged adults in terms of developmental differences in anxiety signs, grouped into aggressive-hostile and insecure-labile categories, and according to sex-role stereotype, as measured by the Broverman Sex-role Stereotype Scale. Adolescent males and females were significantly more likely to obtain more anxiety signs than the two adult groups, although young adults and middle-aged adults did not differ from one another in HFD performance. The most reliable sex difference was that males reveal significantly more aggressive-hostile indices in the HFDs relative to females; no significant sex differences were obtained for number of insecure-labile indices. The degree to which one has adopted a conventional sex-role stereotype was not predictive of anxiety sign differences in HFD performance for either sex or for any age group. PMID:321746

Before 1970, no mixed-age groups existed in Swedish nursery schools. By 1991, 43 percent of children enrolled in nursery school were in mixed-age groups of ages 1 to 6 years, and 37 percent were in groups of children ages 3 to 6 years. Mixed-age groups are assumed to have advantages, including positive influences on learning and social…

In a northern Chicago neighborhood, observational and interview data were collected at parks, school lots, and beaches where adolescents congregate to buy, sell, and use nonopiate drugs. These sites were geographically distinct from areas where heroin is regularly distributed. Users at each area generally resided in the immediate neighborhood, were well known to one another, were predominantly male, displayed similar socioeconomic, religious and ethnic backgrounds, and had attended the same grade schools and high schools. These sites were relatively stable during the summer months, although visitors occasionally changed locations in response to police harassment. Attendance fluctuated with weather and time of day. Drug use was generally confined to the daily use of marihuana and weekend use of alcohol and sedative-hypnotics, but availability seemed to determine the type and frequency of drug use to a greater extent than drug perference. This study suggests the potential of a fieldwork model for prevention and intervention activities prior to the onset of more intense and diversified drug use. PMID:668492

This study investigated the patterns of spirituality, gender, and age in cybergossip practices among Nigerian adolescents. The study utilized a descriptive survey method. Five hundred thirty adolescent students, randomly selected from four major cities in Nigeria, participated in the study. Their age range was 16 to 21. General Spirituality and Gossip Purpose scales were used to collect data from the participants. Data collected were subjected to t test statistics. Findings showed that there is no significant difference in the cybergossiping practices of adolescents based on their levels of spirituality. This reveals that spirituality is not an inhibiting factor in cybergossiping practices among the adolescents. However, there is significant difference between male and female youths in their cybergossiping practices. The results showed that females are more likely than males to be involved in cybergossiping activities. There is also significant difference between early and late adolescents' cybergossiping activities. The implication is that gossip and cybergossip is a natural tendency that involves communicative expression with a pleasure-seeking purpose. It is a habit that excludes no one despite spiritual, gender, or age factors. Therefore, this behavior should be positively directed away from abusive computing and communication. This work is unique because of the need for parents, guardians, and psychologists to design measures to identify and manage various moderating variables in children's computing practices for optimal positive outcomes.

Shakespeare's Romeo and Juliet is used to illustrate several connected theses regarding the relation of the couple to its surrounding social group: these include a couple's oedipal rebellion, the unconscious longing for and hatred of the idealized couple by the large group, the denial of aggression within the couple and its projection onto the group, the impotence of rationality and the conventionalization of sexuality in the large group, and the pervading dynamics of aggression in group formation. Pertinent psychoanalytic theories are briefly summarized, and this combined analysis is applied to the psychoanalyst's attitude regarding adolescent patients' love life. PMID:7360827

The purpose of this investigation was to study the interrelation of andrological status with anthropometric and hormonal descriptions for age-specific features discovery of male sexual system pathological states at technical college students. 147 adolescents aged 15-17 years old were examined. Only 41 of them were found to have no abnormalities in their genital system development; in 35 adolescents sexual development was delayed; and 97 adolescents were found to have various andrological diseases (varicocele, phimosis, gynecomastia, testicular asymmetry, etc.) or clinical signs for development of these diseases. In 26 adolescences delayed sexual development was combined with the andrological pathology. The normal andrological status was usually accompanied with the highest frequency of low values of anthropometric indicators and indices that reflect the influence of various hormonal systems on the bodily constitution, as well as expressed anthropometricheterogeneity. In adolescents with andrological pathology or clinical signs for its development, in all anthropometric parameters the higher values were seen more frequently than low values against the background of highest group anthropometric homogeneity. Summative anthropometric characteristics of the adolescents group with delayed sexual development were between those of the adolescents groups with normal andrological status and andrological pathology The number of correlational relationships of anthropometric and hormonal indicators with the levels of cortisol and dehydroepiandrosteronesulphate was the lowest in the group of adolescents with normal andrological status as compared to their peers with delayed sexual development and andrological pathology. Only in the group of adolescents with normal andrological status the correlation analysis of data showed physiological influence of sexual hormones on anthropometric indicators. Thus, lower influence of sexual system hormones during this ontogenesis stage

Associations between peer group self-identification and smoking were examined among 2,698 ethnically diverse middle school students in Los Angeles who self-identified with groups such as Rockers, Skaters, and Gamers. The sample was 47.1% male, 54.7% Latino, 25.4% Asian, 10.8% White, 9.1% Other ethnicity, and 59.3% children of immigrant parents. Multiple group self-identification was common: 84% identified with two or more groups and 65% identified with three or more groups. Logistic regression analyses indicated that as students endorsed more high-risk groups, the greater their risk of tobacco use. A classification tree analysis identified risk groups based on interactions among ethnicity, gender, and group self-identification. Psychographic targeting based on group self-identification could be useful to design more relevant smoking prevention messages for adolescents who identify with high-risk peer groups. PMID:22458850

The aims of the study were (a) to determine the efficacy of the theory of reasoned action in predicting intention to seek depression treatment in adolescent mothers (n = 64) and a comparison group of adolescent girls (n = 65) and (b) to explore the role of empirically suggested variables (e.g., social support and current symptoms of depression) in increasing the explanatory power of the model. Findings between the two groups differed. Subjective norms, but not attitude, was a significant predictor of intention to seek depression treatment in adolescent mothers (F = 4.82, P = .00; R(2) = .14). In the comparison group of adolescent girls, both attitude and subjective norms predicted intention to seek depression treatment (F = 8.56, P = .00, R(2) = .22). The addition of depressive symptoms and social support increased the explanatory power of the model in the comparison group of adolescent girls (R(2) change = 0.10, P = .02) but resulted in the deletion of subjective norms from the regression equation. Implications for further research and practice are discussed. PMID:19216987

The aim of the study was to assess the possibility of psychological correction in groups to decrease depressiveness among senior schoolchildren. Data of 87 (53 girls and 34 boys) depressive schoolchildren, who participated in the sessions for developing communication skills were analyzed. Depressiveness was assessed by the Depression scale of Minnesota Multiphasic Personality Inventory for Adolescents. Communication skills training method consisted of ten structured hourly sessions. The effectiveness of psychological correction was assessed by the Abbreviated self-awareness scale and the Depression scale of Minnesota Multiphasic Personality Inventory for Adolescents. The results showed decrease in depressiveness and self-worth both among boys and girls (p<0.005). Among boys decrease in average present self-worth scores was noted, while among girls decrease in average present self-worth and average self-worth deviation. Depressiveness as well as self-worth decreased better among boys and girls, which had attended most sessions (p<0.005). CONCLUSIONS. Psychological correction enabled adolescents to decrease the manifestation of depressiveness, and to increase their self-worth: they became more active, communicable, optimistic and in a better mood. Depressiveness among boys decreased better among adolescents, who attended most sessions. Depressiveness decreased better among girls irrespective of their involvement in the sessions, and among actively involved boys. Self-awareness among boys and girls increased better among adolescents, who attended most sessions. Self-awareness increased better among girls irrespective of their involvement in the sessions, and among actively involved boys. PMID:12878825

BACKGROUND Brazil has witnessed dramatic changes in its fertility patterns in recent decades. The decline to below-replacement fertility has been accompanied by increases in the proportion of children born to young mothers. Yet we know little about the well-being of children born to young mothers in Brazil. OBJECTIVE and METHODS Using data from the 2006 Pesquisa Nacional de Demografia e Saúde and a quasi-natural experimental approach, this study examines the implications of maternal age at first birth for the education of Brazilian adolescents. RESULTS We find that being born to a young mother is associated with educational disadvantages in adolescence, but that these disadvantages are attenuated once we account for mothers’ selection into early childbearing. We also find that, in southern Brazil, adolescents born to young mothers have poorer educational outcomes compared with their peers born to older mothers, but that in northern Brazil no such disparities exist. CONCLUSIONS Adolescent educational disadvantages associated with being born to a young mother are not an artifact of selectivity, at least in southern Brazil. Regional variation in the effect of maternal age at first birth on adolescent education suggests the important role of the extended family and the father’s presence as mechanisms through which disadvantages operate.

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.

With the influence of modernization, there is evidence of increasing Thai adolescent sexual activity. The purpose of this study was to describe and compare the intimate relationships of adolescents in different social groups in northern Thailand, and to note the health implications of their behavior. Quantitative and qualitative data from more than 1,750 unmarried young people aged 17-20 years revealed that adolescents from different social and educational backgrounds had significantly different types of intimate relationships. In the Thai context, social class differences are mostly based on young people's educational backgrounds and their families' financial power. Perceptions of love and relationships were interpreted according to social strata and sex. Notably, less well-off young people were likely to engage in much riskier sexual relationships. The present study provides detailed and constructive information to help plan and improve sexual and reproductive health counselling, programs and services for young people in northern Thailand.

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

A prospective longitudinal study beginning whilst the infants were living in the Metera Babies Centre showed that the great majority showed a disorganized attachment during the period of residential care, even though neither abuse/neglect nor subnutrition were involved. There was an initial follow-up post-adoption age at four years. This paper concerns a further follow-up of the 52 adopted adolescents aged 13 years who had spent their first two years of life in Metera Babies Centre. They were compared to 36 adolescents reared in their biological families who, during their infancy, attended full-time public day care. The key aim was to examine continuities and discontinuities between early and contemporary relationships. The Child Attachment Interview was employed in adolescence. The main findings were a significant decrease in the rate of disorganization and a lack of a significant difference between the previously institutionalized group and the family care comparison group on attachment qualities in adolescence. There was not sufficient statistical power, however, to detect a small difference. PMID:25862310

Better understanding risk factors for the development of adolescent emotional and behavioral problems can help with intervention and prevention efforts. Previous studies have found that an early menarcheal age predicts several adolescent problems, including depressive symptoms, delinquency, and early age at first intercourse. Few studies, nevertheless, have explicitly tested (a) whether the associations with menarcheal age vary across racial/ethnic groups or (b) whether the sources of the associations are within-families (i.e., consistent with a direct, causal link) or only between-families (i.e., due to selection or confounding factors). The current study analyzed data from a nationally representative US Sample of females (N = 5,637). We examined whether race/ethnicity moderated the associations between early menarche and several adolescent problems by using multiple-group analyses and we examined the degree to which genetic and environmental factors shared by family members account for the associations by comparing sisters and cousins with differing menarcheal ages. Menarcheal age predicted subsequent depressive symptoms, delinquency, and early age at first intercourse in the population. The magnitudes of the associations were similar across all racial/ethnic groups for all outcomes. The within-family associations (i.e., when comparing siblings and cousins with different menarcheal age) were large and statistically significant when predicting early intercourse, but not the other outcomes. The findings suggest that selection or confounding factors account for the associations between menarcheal age and subsequent depressive symptoms and delinquency, whereas the independent association between menarcheal age and early age at first intercourse is consistent with a direct, causal effect.

Caffeinated energy drinks (EDs) are purported to increase energy and improve performance, but have been associated with adverse health effects and death. EDs are popular among adolescents and young adults, yet little is known about their use among young adolescents. This study explored perceptions, patterns, and contexts of ED use in six focus groups with 40 adolescents aged 12-15 years from two regional Australian schools. A thematic analysis of the data was used to investigate knowledge about ED brands and content, ED use, reasons for ED use, physiological effects, and influences on ED use. Participants were familiar with EDs and most had used them at least once but had limited knowledge of ED ingredients, and some had difficulty differentiating them from soft and sports drinks. EDs were used as an alternative to other drinks, to provide energy, and in social contexts, and their use was associated with short-term physiological symptoms. Parents and advertising influenced participants' perceptions and use of EDs. These findings suggest young adolescents use EDs without knowing what they are drinking and how they are contributing to their personal risk of harm. The advertising, appeal, and use of EDs by adolescents appear to share similarities with alcohol and tobacco. Further research is needed to replicate and extend the current findings, informed by the lessons learned in alcohol research. PMID:24852220

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

The purposes of this study were to collect information regarding the dietary habits of male and female age-group swimmers and report the energy consumptions of these athletes in relation to their daily training demands. Twenty competitive swimmers, who were training 6000 m per day 6 days a week, recorded all fluid and food consumed during a 4-day period. Dietary analysis revealed that 11 swimmers (55%) had calcium intakes below recommended dietary allowances (RDA), while 13 (65%) had iron intakes lower than RDA. Despite identical training loads and body mass, male swimmers had significantly greater (P = 0.004) daily mean (s.d.) energy consumption (3072(732) kcal, 12.9(3.1) MJ) than females (2130(544) kcal, 8.9(2.3) MJ) and were maintaining energy balance. Although the contribution of carbohydrate to total daily energy intake was the same for male (55%) and female swimmers (56%), the females ingested significantly less (P = 0.011) carbohydrate (292(87) g) than the males (404(88) g) and could be considered deficient in dietary carbohydrate with respect to their daily training demands.

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

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

The purpose of this paper is to measure attitudes towards loud music and to evaluate the influence of some variables on such attitudes. The scale of attitudes towards loud music was administered to a sample of 173 sixteen-year old subjects. The majority of the adolescents show neutral or favorable attitudes towards loud music. The sex and environmental noise variables have a non significant influence on this attitude. The majority of the sampled group attend dancing places (clubs, discotheques, etc.) once or twice a month and sometimes listen to loud music at home or at friends' home. Finally, adolescents showing favorable attitudes attend dancing places or listen to loud music more often than those showing unfavorable attitudes. This paper is a first approach to a deeper research to evaluate the possibility of modifying experimentally the attitude towards loud music by means of a message displaying both physical and psychological damage this fashion has caused.

The aims of this study were to determine the effect of age, sex and race distance on velocity (v), stroke rate (SR), stroke length (SL) and stroke index (SI) of subelite adolescent swimmers in competition, and to investigate their pacing strategies during the 100-m and 200-m events. Video footage of 112 adolescent swimmers (56 female; 56 male), competing in the 100-m and 200-m freestyle events, in two age groups (12-14; 15-18 years) was recorded and subsequently analyzed. A MANOVA showed that all stroke parameters significantly differed between sexes and between race distances. The older adolescents had a higher v, a longer SL and a greater SI (p < .01) than the younger adolescents. There were significant interaction effects between age and sex for v, SL and SI. Most adolescents had a SL that was within 7% of that reported for 1992 Olympians, but had up to 16% lower SRs. Separate Friedman's ANOVAs showed that SL differed between successive race quarters for both age groups, both sexes and both race distances. It is likely that physical immaturity, inexperience in competition pacing and within-race fatigue strongly influence the performances of subelite adolescent front crawl swimmers. PMID:25902554

Adolescent survivors of sexual abuse frequently report severe trauma, depression, anxiety, and low self-esteem. While cognitive-behavioral group interventions show promise, interpreting efficacy is problematic due to commonly high attrition. This article reports promising exploratory study findings relating to a 12-week multimodal abuse-specific group intervention with a nonoffending parent/caregiver component. Participants (aged 11 16 years) consisted of six adolescents with severe abuse histories, and their caregivers. Participants completed pre-, post-, and 1-month follow-up measures. The results were consistent with the possibility that the program produced clinically meaningful reductions in abuse-related psychological sequelae, the program had excellent face validity with participants, and there were no dropouts.

The protective role of strength of group identity was examined for youth in a context of protracted political conflict. Participants included 814 adolescents (M age = 13.61, SD = 1.99 at Time 1) participating in a longitudinal study in Belfast, Northern Ireland. Utilizing hierarchical linear modeling, the results show that the effect of exposure to sectarian antisocial behaviors has a stronger effect on youth emotion problems for older adolescents. The results also show that youth with higher strength of group identity reported fewer emotion problems in the face of sectarian antisocial behavior, but that this buffering effect is stronger for Protestants compared to Catholics. Implications are discussed for understanding the role of social identity in post-accord societies. PMID:23682959

Despite high rates of trauma exposure (46%-96%) and significant posttraumatic stress disorder (PTSD; 21%-29%) symptoms in adolescent psychiatric inpatients, there is a dearth of research on effective interventions delivered in inpatient settings. The current report describes the development of Brief STAIR-A, a repeatable 3-module version of skills training in affective and interpersonal regulation (STAIR) developed for adolescents in inpatient care. An uncontrolled design was used to conduct a preliminary examination of the group intervention's effectiveness. Adolescent psychiatric inpatients (N = 38; ages 12 years-17 years) admitted to a public hospital participated in Brief STAIR-A and attended a median of 6 sessions (range 3-36). They completed measures of PTSD and depressive symptom severity, coping skill use, and coping efficacy upon admission and again prior to discharge. Participants reported significant reductions in symptom severity (d = 0.65-0.67), no change in the absolute level of coping skills used (d = 0.16), but greater coping efficacy when discharged from care (d = 0.75). Results from this pilot study suggest that this brief group treatment shows promise for treating adolescents' trauma-related difficulties in inpatient psychiatry settings, but additional research examining its effectiveness is essential.

Purpose To compare mortality rates from motor vehicle accidents (MVA), homicide, and suicide across countries, age groups, and time. Methods The World Health Organization Mortality Database was used to construct age- and gender-specific rates in 26 countries for individuals aged 15 to 34 years during the period 1955 to 1994. The rates were adjusted for differences among countries in the age-and-gender distributions of their populations. Cause-specific rates were compared by country, 4-year age groups, 8-year time blocks, and male/female ratios. Results The proportion of deaths in 15–34-year-olds owing to MVA, homicide, and suicide increased from 26% to 43% over the 40-year study period. Mortality rates differ by country more than time block, peak at ages 15–29 years, and are higher in males than females. Compared to the United States, 24 countries had lower homicide rates and 23 had lower MVA-death rates. Conclusions Despite declining rates of death from other causes, the rates of adolescent and young adult death from MVA, homicide, and suicide remain high in countries throughout the world. The proportion of deaths attributable to these causes increased steadily during the latter half of the 20th century. Fatal risk behaviors begin to increase during adolescence but do not peak until age 30 years, suggesting that the target population for prevention extends well beyond the teenage years. PMID:11755798

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. PMID:24122728

Recent studies of youth aggression have emphasized the role of network-based peer influence processes. Other scholars have suggested that aggression is often motivated by status concerns. We integrate these two veins of research by considering the effects of peer status motivations on subsequent adolescent aggression, net of their own status motivations, prior aggression, and peer behavior. We also explore different levels at which peer effects may occur, considering the effects of reciprocated and unreciprocated friendships as well as larger, meso-level peer groups. We anticipate that peer group effects are magnified by both size and boundedness as measured by Freeman's (1972) Segregation Index. We find that, net of the adolescent's aggression at time 1, both the aggressive behaviors and the status valuations of friends independently increase the likelihood of aggression at time 2, six months later. The aggressive behavior of friends who do not reciprocate the adolescent's friendship nomination has particular impact. The average status valuation of peer groups increases their members' likelihood of aggression, even after controlling for their own attitudes about status, their friends' attitudes, and their friends' aggressive behavior. This effect is magnified in large groups and groups with high Freeman segregation scores. PMID:25152562

The aim of the study is to investigate the determinants of exposure to ETS among Greek adolescents aged 11-17 years old. The GYTS questionnaire was completed by 5,179 adolescents. About 3 in 4 responders (76.8%) were exposed to ETS at home, and 38.5% were exposed to ETS outside of the home. Gender, age group, parental and close friends smoking status were significant determinants of adolescent's exposure to ETS. The results of the study could be valuable for the implementation of public health initiatives in Greece aiming to reduce the burden of adolescent's exposure to passive smoking. PMID:20195445

Health status is often analyzed in population surveys. Self-rated health (SRH) is a single-item summary measure of the perception of one’s health. In Brazil, studies on the SRH of adolescents remain scarce, especially those aiming to understand the domains that compose this construct. Therefore, the aim of this study is to determine the prevalence of poor SRH and its associated factors among 11- to 13-year-olds and 14- to 17-year-olds living in a large urban center in Brazil. This cross-sectional study was conducted using a household survey across Belo Horizonte that included 1,042 adolescents. Stratified logistic regression models were used for each age group to assess the associations between worse SRH and the following variables: socio-demographic, social and family support, lifestyles, psychological health, and anthropometry. Approximately 11% (95% CIs = 8.7–13.6) of the studied adolescents rated their health as poor, and SHR decreased with age among males and females. This trend was more pronounced among girls (from 6.9% among 11- to 13-year-old girls to 16.9% among 14- to 17-year-old girls) than boys (from 8.3% among 11- to 13-year-old boys to 11% among 14- to 17-year-old boys). Worse SRH was associated with family support (as assessed by the absence of parent-adolescent conversations; odds ratio [OR] = 3.5 among 11- to 13-year-olds), family structure (OR = 2.8 among 14- to 17-year-olds), and argument reporting (OR = 8.2 among 14- to 17-year-olds). Among older adolescents, the consumption of fruit fewer than five times per week (OR = 2.4), life dissatisfaction (OR = 2.8), underweight status (OR = 6.7), and overweight status (OR = 2.7) were associated with poor SRH. As adolescents age, their universe expands from their relationship with their parents to include more complex issues, such as their lifestyles and life satisfaction. Therefore, these results suggest the importance of evaluating SRH across adolescent age groups and demonstrate the influence of

Schizophrenia is considered a neurodevelopmental disorder, but whether the adolescent period, proximal to onset, is associated with aberrant development in individuals at clinical high risk (CHR) for psychosis is incompletely understood. While abnormal gray and white matter development has been observed, alterations in functional neuroimaging (fMRI) parameters during adolescence as related to conversion to psychosis have not yet been investigated. Twenty CHR individuals and 19 typically developing controls (TDC), (ages 14-21), were recruited from the Center for Assessment and Prevention of Prodromal States (CAPPS) at UCLA. Participants performed a Sternberg-style verbal working memory (WMem) task during fMRI and data were analyzed using a cross-sectional design to test the hypothesis that there is a deviant developmental trajectory in WMem associated neural circuitry in those at risk for psychosis. Eight of the CHR adolescents converted to psychosis within 2 years of initial assessment. A voxel-wise regression examining the relationship between age and activation revealed a significant group-by-age interaction. TDC showed a negative association between age and functional activation in the WMem circuitry while CHR adolescents showed a positive association. Moreover, CHR patients who later converted to overt psychosis showed a distinct pattern of abnormal age-associated activation in the frontal cortex relative to controls, while non-converters showed a more diffuse posterior pattern. Finding that age related variation in baseline patterns of neural activity differentiate individuals who subsequently convert to psychosis from healthy subjects suggests that these differences are likely to be clinically relevant.

During the past decade, much has been written about adolescents' use of contraception and their experience of pregnancy. Few researchers, however, have distinguished between the experiences of older and younger adolescents. The purpose of this paper is to provide such a comparison. The data were collected during more than 7,000 visits made by 4,318 patients during almost 5 years of operation of an adolescent contraceptive service in the Washington Heights area of New York City. Characteristics of four groups--14 years and younger, 15-17 years, 18-19 years, and 20-21 years--were examined. The youngest teens initiated sexual intercourse 4 years earlier than the oldest group. Among those 14 or younger, 87 percent had never used contraception, and 9 percent had been pregnant. In the oldest group, more than two-thirds had used a contraceptive method, and three-fifths had already experienced a pregnancy. Results of multivariate analyses indicate that older teens are more likely to come to the clinic for contraception and to be consistent users of the first method of contraception that they select. On the other hand, younger teens are significantly more likely to revisit the clinic and to be pregnant at a second or later visit. PMID:3918321

Conducting focus groups with adolescents can be challenging given their developmental needs, particularly with sensitive topics. These challenges include intense need for peer approval, declining social trust, short attention span, and reliance on concrete operations thinking. In this article, we describe an adaptation of interactive performance as an alternative to traditional focus group method. We used this method in a study of discrimination experienced by Muslims (ages 13-17) and of peer pressure to engage in sexual behavior experienced by Hispanic girls (ages 10-14). Recommendations for use of this method include using an interdisciplinary team, planning for large amounts of disclosure towards the end of the focus group, and considering the fit of this method to the study topic.

There is evidence that risks for HIV and sexually transmitted infections among adolescent females are higher for those with older male sexual partners. Yet, little empirical research has been conducted with male adolescents who engage in sexual activity with older men. In this article, we summarize in a number of ways the range of sexual activity reported by an ethnically diverse sample of 200 gay and bisexual male youth (15-22 years old) in Chicago and Miami. A general pattern of progression from oral sex with men to both receptive and insertive anal sex with men appeared to characterize the sample during their adolescence. Further, there appeared to be a high degree of "versatile" positioning among the sexually active gay and bisexual young men, in both age-discrepant and age-concordant dyads. Risk analysis revealed having primarily age-concordant partners to be a significant predictor of sexual risk behavior. HIV risk among young gay and bisexual men engaging in sexual activity with older men may occur not only within a distinct biological context from their heterosexual counterparts, but also in a social context that may not as rigidly bound to traditional assumptions about age, gender, and power. The significant associations among participants with partners who were the same age and the risk behavior measures in this analysis have implications for HIV prevention efforts. PMID:21290255

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

The Resourceful Adolescent Program is an early intervention program designed to enhance psychological resilience in adolescents with emotional problems. Eight adolescents with high anxious and/or depressive symptoms were treated with this 11-session group program. Treatment effects were examined by means of self-report questionnaires of anxiety, depression, and self-efficacy. Pre- and postintervention data showed reductions in anxiety and depression scores and a concomitant increase in adolescents' self-efficacy. PMID:11351893

The current study aimed to situate the development of adolescent narrative identity in the context of past-event conversations between adolescents and their mothers, extending work on conversational contexts in early childhood to adolescence. We examined a cross-section of 63 adolescents with 2 goals: (1) to examine how adolescent age and gender interacted with mothers' scaffolding behaviors and how those interactions were associated with adolescents' narrative processes of meaning-making, vulnerability, and resolution; (2) to examine mothers' behaviors in conversation and how the interactions between those behaviors and event type (important, sad, and happy themes) were associated with those narrative processes. We found that maternal behavior in the conversation was related to adolescent narrative processes, yet this link varied as a function of characteristics of the adolescent and type of event discussed. Overall results suggest that those with potentially less practice at narrating the self in elaborative ways--younger adolescents and boys--receive more supportive scaffolding, and that for those with likely more practice with elaborative narration--girls and older adolescents--mothers engage in more negation behavior. The role of these scaffolding behaviors in adolescent narrative identity development is discussed. PMID:21928885

Background Adolescents present many challenges in providing them effective preventive services and health care. Yet, they are typically the early adopters of new technology (eg, the Internet). This creates important opportunities for engaging youths via eHealth. Objective To describe how adolescents use technology for their health-information needs, identify the challenges they face, and highlight some emerging roles of health professionals regarding eHealth services for adolescents. Methods Using an inductive qualitative research design, 27 focus groups were conducted in Ontario, Canada. The 210 participants (55% female, 45% male; median age 16 years) were selected to reflect diversity in age, sex, geographic location, cultural identity, and risk. An 8-person team analyzed and coded the data according to major themes. Results Study participants most-frequently sought or distributed information related to school (89%), interacting with friends (85%), social concerns (85%), specific medical conditions (67%), body image and nutrition (63%), violence and personal safety (59%), and sexual health (56%). Finding personally-relevant, high-quality information was a pivotal challenge that has ramifications on the depth and types of information that adolescents can find to answer their health questions. Privacy in accessing information technology was a second key challenge. Participants reported using technologies that clustered into 4 domains along a continuum from highly-interactive to fixed information sources: (1) personal communication: telephone, cell phone, and pager; (2) social communication: e-mail, instant messaging, chat, and bulletin boards; (3) interactive environments: Web sites, search engines, and computers; and (4) unidirectional sources: television, radio, and print. Three emerging roles for health professionals in eHealth include: (1) providing an interface for adolescents with technology and assisting them in finding pertinent information sources; (2

The effect of physical training on the natural history of varicocele has received little attention. The aim of the present pilot study was to evaluate the prevalence of idiopathic varicocele in young athletes, in the attempt to find a correlation between the training workload and the clinical grade of varicocele. We evaluated 150 adolescents with an age of 10-16 yr (median age: 13 yr). All these subjects were athletes practicing different sport at agonistic level. One hundred and fifty non-athlete adolescents of matched age (median: 13.5 yr) were used as controls. All underwent physical examination, and if a varicocele was suspected, the diagnosis was confirmed or excluded by echo-color-Doppler examination. The young athletes were stratified into two groups according to the different time spent for training: Group 1-6 h training per week; Group 2-7 to 12 h per week. Statistical analysis was performed. A p<0.05 was considered significant. The physical examination revealed a clinical varicocele on the left side in 20 athletes. A significant positive correlation was observed between the Group 2 and the highest grade of varicocele (r2=0.9918, p=0.0041). In the adolescent group used as control we observed a varicocele in 16 cases. A positive correlation was observed between the number of athletes with varicocele and the highest grade of varicocele (r2=0.96, p=0.02). Sport training does not modify the prevalence of varicocele compared to the general population, but physical activity has to be considered as an aggravating factor in the natural history of varicocele. In countries where sport eligibility is necessary for agonistic sport practice, varicocele should be then considered as a conditioning factor. PMID:15129807

Purpose To estimate the point prevalence of self-medication among adolescents aged 18 years and to evaluate the type of drugs used (either over-the-counter or prescription drugs) and socioeconomic, health-related, and behavioral correlates of self-medication. Methods This cross-sectional study used data from the 1993 Pelotas (Brazil) Birth Cohort Study. Data were obtained through the administration of a questionnaire to adolescents aged 18 years. The outcome variables were point prevalence of medicine use and self-medication collected by self-report. The independent variables studied were gender, continuous medicine use, socioeconomic status, schooling, self-rated health, body mass index, and physical activity levels. Medicines were classified into therapeutic groups according to the Anatomical Therapeutic Chemical classification system. Results A total of 4,106 adolescents were interviewed. The point prevalence of medicine use was 41.1% (95% confidence interval [CI] 39.6–42.6), and the proportion of self-medication among medicine users was 65.1% (95% CI 62.8–67.4). The point prevalence of self-medication was 26.7% (95% CI 25.4–28.1), and it was higher among female adolescents, those more educated, and those who rated their health as poor. Out of the drugs used for self-medication (58% of all drugs used), 1,003 (78.7%) were nonprescription drugs and 271 (21.3%) were prescription drugs. The most frequently used drugs for self-medication were analgesics (56.1%), systemic antihistamines (7.4%), and anti-inflammatory and antirheumatic products (7.1%). Conclusions A high point prevalence of self-medication was found among adolescents, which is particularly concerning due to high use of prescription drugs for self-medication. Interventions are needed to promote rational use of medicines in this population. PMID:24713443

The current work aims to study both the peer group and family influence on adolescent behaviour. In order to achieve the aforementioned objective, an explanatory model based on the Structural Equations Modelling (SEM)was proposed. The sample used was the group of adolescents that participated in the Portuguese survey of the European study Health Behaviour in School-aged Children (HBSC). The Portuguese survey included students from grades 6, 8 and 10 within the public education system, with an average age of 14 years old (SD=1.89). The total sample of the HBSC study carried out in 2006 was 4,877; however with the use of the SEM, 1,238 participants were lost out of the total sample. The results show that peers have a direct influence in adolescents’ risk behaviours. The relationship with parents did not demonstrate the expected mediation effect, with the exception of the following elements: relation between type of friends and risk behaviour; and communication with parent and lesser involvement in violence behaviours and increased well-being. The negative influence of the peer group is more connected to the involvement in risk behaviours, whilst the positive influence is more connected with protective behaviours. PMID:22980148

Background: Neurocognitive tests are routinely used to assess cognitive domains in the adolescents for assessing cognitive deficits and for therapeutic interventions. Now they are being used to assess their mental abilities in athletics too. Aim: To study the effect of age and gender differences on routinely used common paper and pencil neuro-cognitive tests in adolescents and present the trends of normative data of Indian adolescent population. Settings and Design: Present study was conducted as a joint collaboration between Department of Physiology and Jawahar Navodaya school, Puducherry, India. Materials and Methods: Four hundred and thirty nine adolescents in the age group of 12 to 17 y (M = 250, F= 189) were selected in the present study after meeting the inclusion and exclusion criteria. Subjects were administered commonly used paper and pencil neuropsychological tests in the following order: Two Target Letter Cancellation test, Trail Making test A and B, Ruff Figural Fluency test (RFFT). Statistical Analysis: We divided the students based on their age into six groups - from age 12–17. Neurocognitive parameters were compared between these age groups using one-way-ANOVA with Bonferroni post-hoc test. Only the p-values for one, two and three year difference were considered. The same analysis was repeated for each gender separately. We compared males and females from the entire sample using unpaired t test. We then repeated the same test to compare males and females in each age group separately. Pearsons correlation was done to find correlation between the neurocognitive test parameters using the entire sample size. Then the correlation was done again after adjusting for age. All the statistical analysis was done using Statistical package for social sciences (SPSS) version 19. Results: Year wise normative data has been presented for all the age groups from 12 y onwards to 17 y. The results showed a consistent improvement in performance on the tested neuro

In the present paper, one remote sensing index-age group vegetation index (AGVI) was put forward, and its feasibility was verified. Taking 518 groups of pine forest age group data collected in 13 counties (cities) of Sanming, Jiangle, Shaxian, Nanping, Huaan, Yunxiao, Nanping, Anxi, Putian, Changting, Jianyang, Ningde and Fuqing, Fujian Province and HJ-1 CCD multi-spectral image at the same time-phase as the basis, the spectrum differences of blue, green, red, near infrared and NDVI of each age group were analyzed, showing the characteristics of young forest>middle-aged forest>over-mature forest>mature forest>near mature forest at near infrared band and mature forest>near mature forest>over-mature forest>young forest>middle-aged forest at NDVI, thus the age group vegetation index (AGVI) was constructed; the index could increase the absolute and relative spectrum differences among age groups. For the pine forest AGVI, cluster analysis was conducted with K-mean method, showing that the division accuracy of pine forest age group was 80.45%, and the accurate rate was 90.41%. Therefore, the effectiveness of age group vegetation index constructed was confirmed. PMID:25358177

This scoping review was conducted to understand the extent, range, and nature of current research on adolescents and young adults (AYA) with cancer and distress, depression, and anxiety (DDA). This information is necessary to find and aggregate valuable data on the AYA population embedded in generalized studies of DDA. Keyword searches of six relevant electronic databases identified 2156 articles, with 316 selected for abstract review and 40 for full text review. Full-text reviews and data extraction resulted in 34 studies being included, which ranged widely in design, sample size, age-range categorization, analysis methods, DDA measurement tool, overall study rigor, and quality of evidence. Studies very seldom reported using theory to guide their age categorization, with only four studies giving any rationale for their age-group definitions. All 34 studies found a significant association between at least one DDA construct and the younger age group relative to the older age groups at some point along the cancer trajectory. However, age as an independent risk factor for DDA is still unclear, as the relationship could be confounded by other age-related factors. Despite the wide range of definitions and effect sizes in the studies included in this review, one thing is clear: adolescents and young adults, however defined, are a distinct group within the cancer population with an elevated risk of DDA. Widespread adoption of a standard AYA age-range definition will be essential to any future meta-analytical psycho-oncology research in this population. PMID:26697266

Very few studies have examined the pathways to delinquency and causal factors for demographic subgroups of adolescents in a different culture. This article explores the effects of gender, age, and family socioeconomic status (SES) in an integrated model of strain, social control, social learning, and delinquency among a sample of Chinese adolescents. ANOVA is used to check for significant differences between categories of demographic groups on the variables in the integrated model, and the differential effects of causal factors in the theoretical path models are examined. Further tests of interaction effects are conducted to compare path coefficients between "high-risk" youths (i.e., male, mid-teen, and low family SES adolescents) and other subgroups. The findings identified similar pathways to delinquency across subgroups and clarified the salience of causal factors for male, mid-teen, and low SES adolescents in a different cultural context.

Ephedra-containing dietary supplements are consumed to improve sports performace, but may carry risks of cardiac and neurological adverse events. Little is known of their use by young athletes. Our aim was to determine the prevalence and patterns of ephedra use among high school athletes. An anonymous survey was performed in Rochester, Minnesota on high school athletes who participated in fall sports during 2003-04. Parental consent was obtained for athletes under age 18 years. Surveys were distributed at preparticipation examinations and in- school survey stations. The response rate to the survey was 68.2%, or 311 respondents out of a possible 456 with consent (or 26% of all 1197 athletes eligible prior to the consent process). Seven of 311 (2.3%) respondents used dietary supplements containing ephedra. Only one of seven users (14.3%) knew that the supplements they used contained ephedra. Ephedra use was more common in boys (five) than girls (two). Ephedra use was only found in 17 and 18-year-olds. The most common sports among ephedra users were football, track and field, and weightlifting. This study suggests that Ephedra use was infrequent among the young athletes in this population. However, ephedra users were generally unaware that the dietary supplements they consumed contained ephedra. Users were more likely to participate in football, track and field, and weightlifting. Ephedra users were likely to obtain supplements from their peers, and were largely uninformed of the content of their supplements. Key Points Ephedra is an herbal stimulant used as an ergogenic aide. Adolescent ephedra users most commonly obtain it from their friends. Adolescent athletes are likely to take ephedra unknowningly. PMID:24353458

Interventions targeting parents of young children have shown effectiveness, but research is lacking about best practices for engaging parents of early adolescents. Low levels of enrollment and attendance in parenting interventions present major problems for researchers and clinicians. Effective and efficient ways to engage and collaborate with parents to strengthen parenting practices and to promote healthy development of early adolescents are needed. This exploratory mixed methods study examined the feasibility of three methods of engaging parents in positive parenting activities. Participants were parents of youth ages 11–13 enrolled in three urban, public middle schools in neighborhoods characterized by high rates of community violence. Families (N = 144) were randomized into one of three interventions: six home sessions, two home sessions followed by four group sessions, or six group sessions. The majority of parents were single, non-Hispanic, African American mothers. Urban parents of middle school students were more likely to participate in home visits than in group sessions; offering a combination did not increase participation in the group sessions. As only 34% of those who consented participated in the intervention, qualitative data were examined to explain the reasons for non-participation. PMID:27122960

This article concerns the manner in which group interaction during focus groups impacted upon the data generated in a study of adolescent sexual health. Twenty-nine group interviews were conducted with secondary school pupils in Ireland, and data were subjected to a qualitative analysis. In exploring the relationship between method and theory generation, we begin by focusing on the ethnographic potential within group interviews. We propose that at times during the interviews, episodes of acting-out, or presenting a particular image in the presence of others, can be highly revealing in attempting to understand the normative rules embedded in the culture from which participants are drawn. However, we highlight a specific problem with distinguishing which parts of the group interview are a valid representation of group processes and which parts accurately reflect individuals' retrospective experiences of reality. We also note that at various points in the interview, focus groups have the potential to reveal participants' vulnerabilities. In addition, group members themselves can challenge one another on how aspects of their sub-culture are represented within the focus group, in a way that is normally beyond reach within individual interviews. The formation and composition of focus groups, particularly through the clustering of like-minded individuals, can affect the dominant views being expressed within specific groups. While focus groups have been noted to have an educational and transformative potential, we caution that they may also be a source of inaccurate information, placing participants at risk. Finally, the opportunities that focus groups offer in enabling researchers to cross-check the trustworthiness of data using a post-interview questionnaire are considered. We conclude by arguing that although far from flawless, focus groups are a valuable method for gathering data about health issues. PMID:15955604

This article investigates the life success at ages 32 and 48 of four categories of males: nonoffenders, adolescence-limited offenders (convicted only at ages 10-20), late-onset offenders (convicted only at ages 21-50), and persistent offenders (convicted at both ages 10-20 and 21-50). In the Cambridge Study in Delinquent Development, 411 South London males have been followed up from age 8 to 48 in repeated personal interviews. There was considerable continuity in offending over time. Persistent offenders had the longest criminal careers (averaging 18.4 years), and most of them had convictions for violence. Persistent offenders were leading the most unsuccessful lives at ages 32 and 48, although all categories of males became more successful with age. By age 48, the life success of adolescence-limited offenders was similar to that of nonoffenders. The most important risk factors at ages 8-18 that predicted which offenders would persist after age 21 were heavy drinking at age 18, hyperactivity at ages 12-14, and low popularity and harsh discipline at ages 8-10. The most important risk factors that predicted which nonoffenders would onset after age 21 were poor housing and low nonverbal IQ at ages 8-10, high neuroticism at age 16, and anti-establishment attitudes and motoring convictions at age 18. It was suggested that nervousness and neuroticism may have protected children at risk from offending in adolescence and the teenage years. PMID:19172660

There is limited evidence concerning the role of social networks on the oral health of adolescents. This study assessed the association between the participation of adolescents in community groups and dental caries. A cross-sectional household-based study was carried out involving 200 subjects aged 15-19 years living in a deprived area in the state of Amazon, Brazil. Dental caries was assessed through dental examinations using the DMFT index conducted by a single examiner who was previously calibrated. Four dental caries outcomes were investigated, including caries experience (DMFT score), current caries (number of current decayed teeth), missing teeth due to caries, and the care index (ratio between number of filled teeth and DMFT score). Details of participation of adolescents in community groups, demographic and socioeconomic data and information on dental visiting were obtained through individual interviews. All caries measures were significantly higher in adolescents who did not participate in community groups compared to their counterparts. Multivariate Poisson regression showed that participation of adolescents in community groups was independently associated with all dental caries outcomes. After adjusting for confounders, participation in community groups was statistically associated with lower DMFT score (ratio of mean, RM: 0.33, 95% CI: 0.24-0.46), fewer decayed teeth (RM: 0.23, 95% CI: 0.11-0.47), fewer missing teeth (RM: 0.28, 95% CI: 0.17-0.47), and higher care index (RM: 1.69, 95% CI: 1.24-2.29) than those who did not participate. Participation of adolescents in community activities was related to lower levels of dental caries. PMID:26346951

Given the rise in depression disorders in adolescence, it is important to develop and study depression prevention programs for this age group. The current study examined the efficacy of Interpersonal Psychotherapy-Adolescent Skills Training (IPT-AST), a group prevention program for adolescent depression, in comparison to group programs that are typically delivered in school settings. In this indicated prevention trial, 186 adolescents with elevated depression symptoms were randomized to receive IPT-AST delivered by research staff or group counseling (GC) delivered by school counselors. Hierarchical linear modeling examined differences in rates of change in depressive symptoms and overall functioning from baseline to the 6-month follow-up assessment. Cox regression compared rates of depression diagnoses. Adolescents in IPT-AST showed significantly greater improvements in self-reported depressive symptoms and evaluator-rated overall functioning than GC adolescents from baseline to the 6-month follow-up. However, there were no significant differences between the two conditions in onset of depression diagnoses. Although both intervention conditions demonstrated significant improvements in depressive symptoms and overall functioning, results indicate that IPT-AST has modest benefits over groups run by school counselors which were matched on frequency and duration of sessions. In particular, IPT-AST outperformed GC in reduction of depressive symptoms and improvements in overall functioning. These findings point to the clinical utility of this depression prevention program, at least in the short-term. Additional follow-up is needed to determine the long-term effects of IPT-AST, relative to GC, particularly in preventing depression onset. PMID:26638219

OBJECTIVE: To evaluate the prevalence of weight excess in children and adolescents attending public and private schools of Campinas, Southeast Brazil, according to age group. METHODS: Cross-sectional study that enrolled 3,130 students from 2010 to 2012. The weight and the height were measured and the body mass index (BMI) was calculated. The students were classified by BMI Z-score/age curves of the World Health Organization (WHO)-2007 (thinness, normal weight, overweight and obesity) and by age group (7-10, 11-14 and 15-18 years). Multinomial logistic regression analysis was applied to verify variables associated to overweight and obesity. RESULTS: Among the 3,130 students, 53.7% attended public schools and 53.4% were girls. The prevalence of weight excess (overweight or obesity) was higher in private schools (37.3%) than in public ones (32.9%) and among males (37.5%), compared to females (32.7%; p<0.05). The chance of having weight excess in children aged 7-10 years was more than twice of those over 15 years old (OR 2.4; 95%CI 2.0-3.0) and it was 60% higher for the group with 11-14 years old (OR 1.6; 95%CI 1.3-2.0). The chance of being obese was three times higher in 7-10 years old children than in the adolescents with 15-18 years old (OR 4.4; 95%CI 3.3-6.4) and 130% higher than the group with 11-14 years old (OR 2.3; 95%CI 1.6-3.2). CONCLUSIONS: The prevalence of weight excess in Campinas keeps increasing at an alarming rate, especially in the younger age group. PMID:25119751

We examined identity development as a moderator of the relation between peer group pressure and control and adolescents' engagement in risk behaviors. Participants (n=1070; M(age)=15.45 years) completed a self-report measure of identity exploration, the degree to which they have explored a variety of self-relevant values, beliefs and goals, and identity commitment, the degree to which they have secured a personal identity. Participants further reported on their frequency of risk behaviors (substance use and general deviancy) and experienced peer group pressure and control. Results confirmed that identity commitment was a buffer of substance use and identity exploration was a buffer of general deviancy in more pressuring peer groups. In more controlling peer groups, teens with greater identity commitment engaged in less risk behavior than teens with low-identity commitment. Thus, identity development may be a suitable target to deter negative effects of peer pressure in high-risk adolescents. PMID:22265669

Comparative studies examining the difference between empirically supported substance abuse treatments versus their culturally accommodated counterparts with participants from a single ethnic minority group are frequently called for in the literature but infrequently conducted in practice. This randomized clinical trial was conducted to compare the efficacy of an empirically supported standard version of a group-based cognitive-behavioral treatment (S-CBT) to a culturally accommodated version (A-CBT) with a sample of Latino adolescents primarily recruited from the juvenile justice system. Development of the culturally accommodated treatment and testing was guided by the Cultural Accommodation Model for Substance Abuse Treatment (CAM-SAT). Seventy Latino adolescents (mean age = 15.2; 90% male) were randomly assigned to 1 of 2 group-based treatment conditions (S-CBT = 36; A-CBT = 34) with assessments conducted at pretreatment, posttreatment, and 3-month follow-up. Longitudinal Poisson mixed models for count data were used to conduct the major analyses. The primary outcome variable in the analytic models was the number of days any substance was used (including alcohol, except tobacco) in the past 90 days. In addition, the variables ethnic identity, familism, and acculturation were included as cultural moderators in the analysis. Although both conditions produced significant decreases in substance use, the results did not support a time by treatment condition interaction; however, outcomes were moderated by ethnic identity and familism. The findings are discussed with implications for research and practice within the context of providing culturally relevant treatment for Latino adolescents with substance use disorders. PMID:25602465

Osteosarcoma is the most common type of bone cancer in children and adolescents. MicroRNAs (miRNAs) play important roles in the development, differentiation, and function of different cell types and in the pathogenesis of various human diseases. miRNAs are differentially expressed in normal and cancer cells. The investigation of miRNA expression between healthy subjects and patients with osteosarcoma is crucial for future clinical trials. In this study, the expression levels of miRNAs were detected by qRT-PCR. Correlation between expression levels of tow miRNAs and different clinicopathological characteristics were analyzed using the χ (2) test. Survival rate was detected using the log-rank test and Kaplan-Meier method. qRT-PCR was shown that expression levels of miR-29b and miR-422a were strongly decreased in osteosarcoma bone tissue compared with noncancerous bone tissues. Our result indicated that the low expression levels of miR-29b and miR-422a showed strong correlation with large tumor size (P = 0.20; 0.029), advanced TNM stage (P = 0.001; 0.012), distant metastasis (P = 0.008; 0.019), and grade of tumor (P = 0.009; 0.016). Kaplan-Meier survival analysis showed that the low expressions of miR-29b/miR-422a were correlated with shorter time overall survival (log-rank test, P = 0.009; P = 0.013). Moreover, multivariate Cox proportional hazards model indicated that miR-29b and miR-422a (P = 0.024; P = 0.016) were independent prognostic markers of overall survival of patients. Our result indicated that downregulation of miR-29b and miR-422a may be linked to the prediction of poor prognosis, indicating that miR-29b and miR-422a may be a valuable prognostic marker for osteosarcoma patients.

Group intervention has been the most commonly employed treatment modality for adolescents with substance use disorders (SUD). Evidence has been accumulating in support for the efficacy of diverse forms of group therapy that have been utilized with adolescents. It has been argued however, that aggregation of youths who display problem behavior into group interventions may, under some conditions, produce iatrogenic effects on all participants. This assertion known also as "deviancy training" and its presumed effect on treatment outcomes has created a barrier to progress regardless of the fact that it has not been tested or empirically supported in heterogeneous groups of adolescents treated for SUD. It is imperative to optimize group intervention while considering how to prevent, reduce and control, potentially iatrogenic effects associated with the aggregation of antisocial youths in heterogeneous groups. The main objective of this review is to address the challenges and opportunities regarding group treatment of adolescent SUD. PMID:16051443

This paper presents the study on the family risk factors associated with adolescent pregnancy among adolescent girls and their families in Quito, Ecuador. The study aimed to identify characteristics within the family associated with adolescent pregnancy. A total of 135 female adolescents (aged 12-19 years) and their families were separately interviewed. 47 were pregnant and attending prenatal care at an inner city hospital in Quito, and 88 were nonpregnant students from schools located within the same geographical area. Results showed that when compared to their pregnant peers, more nonpregnant adolescents lived with their biological parents (p 0.002); they showed higher school performance (p 0.001); and more values and religiosity (p 0.0001). Pregnant adolescents reported lower mother-daughter and father-daughter communication (p 0.02), lesser life satisfaction in general, and more school and economic difficulties (p 0.001). Moreover, they were less likely to find support for their problems in or outside the family (p 0.0001) and showed higher levels of depression (68.8%) and sexual abuse (14.9%). Parental education was higher in the families of nonpregnant adolescents and both parents worked to provide financial support for the family. PMID:10447044

Objectives We identified peak annual incidence rates for medical and nonmedical use of prescription opioid analgesics, stimulants, sedatives and anxiolytics (controlled medication), and explored cohort effects on age of initiation. Methods Data were gathered retrospectively between 2009–2012 from Detroit area students (n=5185). Modal age at last assessment was 17 years. A meta-analytic approach produced age-, year-, and cohort-specific risk estimates of first-time use of controlled medication. Cox regression models examined cohort patterns in age of initiation for medical and nonmedical use with any of four classes of controlled medication (opioid analgesics, stimulants, sedatives or anxiolytics). Results Peak annual incidence rates were observed at age 16, when 11.3% started medical use, and 3.4% started using another person’s prescription for a controlled medication (i.e., engaged in nonmedical use). In the more recent birth cohort group (1996–2000), 82% of medical users and 76% of nonmedical users reported initiating such use by age 12. In contrast, in the less recent birth cohort group (1991–1995), 42% of medical users and 35% of nonmedical users initiated such use by age 12. Time to initiation was 2.6 times less in the more recent birth cohort group (medical use: adjusted hazard ratio [aHR]=2.57 [95% confidence interval (CI)= 2.32, 2.85]; nonmedical use: aHR=2.57 [95% CI=2.17, 3.03]). Conclusions Peak annual incidence rates were observed at age 16 for medical and nonmedical use. More recent cohorts reported initiating both types of use at younger ages. Earlier interventions may be needed to prevent adolescent nonmedical use of controlled medication. PMID:26291544

People presumably choose and create their daily environments according to their personality. Prior research shows that, for example, more extraverted people engage more often in social situations, and more conscientious people engage more often in work-related activities compared with less extraverted or less conscientious people, respectively. The current study examined such personality-situation transactions in people's daily life. Based on the assumption that older people know themselves and their personality better than younger people, we investigated whether momentary and proximate personality-situation associations (i.e., changing from 1 type of situation into another) increase with older age. Three-hundred and 78 people aged 14 to 82 years described their Big Five traits and took part in a 3-week experience-sampling phase. Using mobile-phone based assessments in daily life, participants reported on average 55 times on their momentary situation. Multilevel modeling results showed that personality-situation associations varied with the age of participants. Some of the "established" personality-situation associations, such as for extraversion and time spent with friends or conscientiousness and time spent with work activities, were only observed in adolescence and young adulthood. In contrast, other personality-situation associations appeared only in late adulthood, such as for openness and time spent with friends. Yet most personality-situation associations did not vary significantly with people's age. In addition, personality traits predicted maintaining or entering personality-congruent situations. The latter results point to the active role of personality in shaping one's environment. The findings imply that some personality-situation transactions may be largely similarly across the life span.

This study explores the contribution of food group intakes to micronutrient adequacy among 2379 girls in the National Growth and Health Study during three age periods (9–13, 14–18, and 19–20 years). Data on food and nutrient intakes from 3-day diet records over 10 years were used to estimate mean intakes and percent meeting Dietary Guidelines (DGA) recommendations for food intakes and Institute of Medicine’s recommendations for vitamins and minerals. More than 90% of girls failed to consume the recommended amounts of fruit, vegetables and dairy; 75% consumed less than the recommended amounts in the “meat” group. The vast majority of girls of all ages had inadequate intakes of calcium, magnesium, potassium, and vitamins D and E. In contrast, they consumed >750 kcal/day (~40% of total energy) from the DGA category of solid fat and added sugars, about five times the recommended maximum intakes. This study shows the importance of consuming a variety of foods in all five food groups, including those that are more energy dense such as dairy and meats, in order to meet a broad range of nutrient guidelines. Diet patterns that combined intakes across food groups led to greater improvements in overall nutritional adequacy. PMID:23201841

Little is known about accurate prevalence and associated factors of deliberate self-harm (DSH) among adolescents in Asian countries. In this study, the prevalence and associated factors of DSH among adolescents in Japan were examined. Data were derived from a cross-sectional survey using an anonymous self-report questionnaire and enrolling 8,620 adolescents aged 12-15 and 9,484 aged 15-18. DSH in the previous 12 months was reported by 3.3% (95% CI, 2.9-3.7) of junior and 4.3% (3.9%-4.7%) of senior high school respondents. The prevalence was more than four times as high among girls as among boys for both age groups. DSH was further strongly associated with having suicidal thoughts, having depression/anxiety symptoms, and having used recreational drugs. These associated factors were similar for both sexes and for both older and younger teenagers. A substantial minority of adolescents present with DSH, even among those aged 12-15. The prevalence of DSH in Japan was in the lower ranges of those reported for Western countries. The identified associated factors were not dissimilar from those reported in the West. PMID:22889157

There are multiple factors that can affect the risk of tobacco use in adolescence. By analyzing these factors together we can disentangle the specific relevance of each of them in shaping teenagers' individual behavior. The goal of this research study is to deepen our understanding of the relationship between tobacco use in adolescence and socio-demographic and socio-emotional variables. We worked with a representative sample of 2,289 Catalan teenagers (aged 15-18) who responded to a questionnaire drawn up by the Families and Children Panel. Regression models were developed to assess the statistical associations of different mood states (sadness, nervousness and loneliness), peer-group characteristics and parenting styles, with tobacco use. The results indicate that addictive behavior is more likely when teenagers show negative mood states, controlling for socio-demographic variables and other risk factors. Among these additional factors, authoritative parenting styles reduce the risk of tobacco use, compared to authoritarian, permissive and neglectful parenting. Extensive tobacco use within the peer group is the risk factor most strongly associated with teenagers' individual behavior. PMID:23241718

While adults are assumed to have the capacity to consent to medical research, and young children to have no capacity, adolescents' capacity to consent is not well described. Adapting the MacArthur Competence Assessment Tool for Clinical Research (MacCAT-CR), we describe adolescents' capacity to consent to medical research and factors influencing that capacity. Our pilot study included a community-based sample of 30 adolescents, 14 to 21 years of age, who completed the MacCAT-CR after undergoing a simulated informed consent process. We found that adolescents' capacity to consent to research was associated with age, health literacy, and family affluence. These findings suggest that investigators and institutional review boards should be aware that factors other than age may influence capacity to consent, and, for modifiable factors, such as health literacy, consent processes for medical research with adolescents can be modified.

Introduction: Tobacco cessation treatments have not been evaluated among Alaska Native (AN) adolescents. This pilot study evaluated the feasibility and the potential efficacy of a targeted cessation intervention for AN youth using a group randomized design. Methods: Eight villages in western Alaska were randomly assigned to receive the intervention (n = 4 villages) or a delayed treatment control condition (written materials only; n = 4 villages). Ten adolescents aged 12–17 years were targeted from each village with a planned enrollment of 80. The intervention was held over a weekend, and youth traveled from their villages to quit tobacco use with other teens. The intervention comprised 8hr of group-based counseling. Talking circles, personal stories from elders, and recreational activities were included to enhance cultural acceptability and participation. Newsletters were mailed weekly for 5-weeks postprogram. Assessments were conducted at baseline, week 6 (end-of-treatment), and 6 months. Self-reported tobacco abstinence was confirmed with salivary cotinine. Results: Recruitment targets were met in the intervention (41 enrolled) but not in control villages (27 enrolled). All intervention participants attended the weekend program. Retention was high; 98% of intervention and 86% of control participants completed 6-month follow-up. The 7-day point-prevalence self-reported tobacco abstinence rates for intervention and control participants were 10% (4/41) and 0% (0/27) at both week 6 and 6 months (p = .15). Only 1 adolescent in the intervention condition was biochemically confirmed abstinent at week 6 and none at 6 months. Conclusion: The intensive individual-focused intervention used in this study was feasible but not effective for tobacco cessation among AN youth. Alternative approaches are warranted. PMID:24532352

In recent years, concern has increased over the rapid growth of health care spending, especially spending on behalf of the aged. In 1987, those 65 years or over comprised 12 percent of the population but consumed 36 percent of total personal health care. This article is an examination of the current and future composition of the population and effects on health care spending. National health accounts aggregates for 1977 and 1987 are split into three age groups, and the consumption patterns of each group are discussed. The variations in spending within the aged cohort are also examined. PMID:10313274

Patients with equestrian injuries were identified in the trauma registry from 2004 to 2007. We a priori divided patients into three groups: 0 to 18 years, 19 to 49 years, and 50 years old or older. There were 284 patients identified with equestrian-related trauma. Injury Severity Score for the three major age categories 0 to 18 years, 19 to 49 years, and 50 years or older, were 3.47, 5.09, and 6.27, respectively. The most common body region injured among all patients was the head (26.1%). The most common injuries by age group were: 0 to 18 years, upper extremity fractures; 19 to 49 year olds, concussions; and 50 years or older, rib fractures. Significant differences were observed among the three age groups in terms of percent of patients with rib fractures: percent of patients with rib fractures was 2, 8, and 22 per cent in age groups 0 to 18, 19 to 49, and 50 years or older, respectively. We found different patterns of injuries associated with equestrian accidents by age. Head injuries were commonly seen among participants in equestrian activities and helmet use should be promoted to minimize the severity of closed head injuries. Injury patterns also seem to vary among the various age groups that ride horses. This information could be used to better target injury prevention efforts among these patients. PMID:24887673

Three hundred and fifty-seven sera selected at random from hospital patients of all ages were examined for rotavirus antibodies using indirect immunofluorescence (FA) and complement fixation levels (CFT). Three hundred and fourteen of these were also tested for neutralizing antibodies to human rotavirus. Sera from patients admitted with a diagnosis of acute gastroenteritis were excluded from this survey. FA antibodies were found in newborn infants but fell to undetectable titres at 3 months. The highest titres were found in children between the ages of one and three years. In older age groups, the model titre fell gradually with increasing age until, in sera from those above 70 years of age, FA antibodies were almost undetectable. The same pattern was observed with neutralizing antibodies. A high model titre of CF antibodies was only found in sera from those aged one to three years. PMID:200676

This article highlights the significance food may have in group therapy with children and adolescents and its meanings for particular group members. It focuses on the interactions between the group members and leaders in response to food. Along with providing actual nutrition, food represents emotional and symbolic nurturing, and may trigger salient conflicts and issues with which group members are struggling. An essential role of the group leader is to manage conflicts that may be evoked by the provision of food. Examples are provided to illustrate themes and meanings related to food in group therapy with children and adolescents. PMID:11797244

The Multiple-Family Group Intervention (MFGI) was developed to address the need for an effective and yet affordable treatment for reducing recidivism for incarcerated adolescents and altering the families' coercive interactional patterns from an affect regulation and attachment perspective. The 8-week MFGI program was conducted in two Indiana juvenile correctional institutions. The research study utilized pre- and postintervention assessments and a 6-month follow-up assessment. Data from both male (n = 43) and female (n=30) adolescents were combined, yielding a total sample of 140 respondents (73 adolescents, 67 caretakers). The 6-month follow-up assessment indicated a recidivism rate of only 44% compared to the national norm of 65-85%. Linear growth models were fit to determine the nature of the changes in adolescent behavior over the three assessments. Adolescents and caregivers reported that adolescents' externalizing behaviors significantly declined over time. Adolescent-reported internalizing symptoms as well as their alcohol and drug use significantly declined over the follow-up period, while caregiver reports of these behaviors showed no change over time. Adolescent-reported attachment to their parents, particularly mothers, increased significantly as did both adolescent and caregiver-reported functional affect regulation. PMID:17257385

The present study examines age differences in the memory benefits from group-referncing. While prior work establishes that the memory performance of younger and older adults similarly benefits from relating information to the self, this study assessed whether those benefits extend to referencing a meaningful group membership. Young and older adult participants encoded trait words by judging whether each word describes themselves, describes their group membership (selected for each age group), or is familiar. After a retention interval, participants completed a surprise recognition memory test. The results indicate that group-referencing increased recognition memory performance compared to the familiarity judgements for both young and older groups. However, the group-reference benefit is limited, emerging as smaller than the benefit from self-referencing. These results challenge previous findings of equivalent benefits for group-referencing and self-referencing, suggesting that such effects may not prevail under all conditions, including for older adults. The findings also highlight the need to examine the mechanisms of group-referencing that can lead to variability in the group-reference effect. PMID:26252870

Efficacious treatments are only valuable to the extent that they are used. Given ethnic disparities in mental health service utilization, this preliminary study examined differences between Hispanic and non-Hispanic White (NHW) adolescents' ratings of the acceptability of depression treatments and related constructs. Female high school students (N = 67; 54% Hispanic) read a vignette describing a depressed adolescent and rated the acceptability of four single treatments for depression (i.e., cognitive-behavioral therapy, interpersonal therapy, family therapy, and pharmacotherapy) and three treatment combinations. Hispanic adolescents completed a self-report measure of acculturation and all adolescents were interviewed about their beliefs of the causes of depression. Results showed more similarities than differences between ethnic groups, with Hispanic and NHW adolescents favoring psychological treatments over pharmacotherapy. Among Hispanic participants, overall ratings of treatment acceptability were significantly higher for bicultural adolescents than Hispanic adolescents immersed predominantly in non-Hispanic culture. Hispanic and NHW adolescents generally showed similar beliefs about the causes of depression, with both groups endorsing personality and cognitions at high rates, but Hispanics were significantly less likely than NHWs to endorse trauma as a cause of depression. Implications for decreasing ethnic disparities in unmet need for treatment are discussed. PMID:23834256

Objective To examine the factor structure of Attention-Deficit/Hyperactivity Disorder (ADHD) in a clinical sample of 1373 children and adolescents with ADHD and their 1772 unselected siblings recruited from different countries across a large age range. Hierarchical and correlated factor analytic models were compared separately in the ADHD and sibling samples, across three different instruments and across parent and teacher informants. Specific consideration was given to factorial invariance analyses across different ages and different countries in the ADHD sample. Method A sample of children and adolescents between 5 and 17 years of age with ADHD and their unselected siblings was assessed. Participants were recruited from seven European countries and Israel. ADHD symptom data came from a clinical interview with parents (PACS) and questionnaires from parents and teachers (Conners Parent and Teacher). Results A hierarchical general factor model with two specific factors best represented the structure of ADHD in both the ADHD and unselected sibling groups, and across informants and instruments. The model was robust and invariant with regard to age differences in the ADHD sample. The model was not strongly invariant across different national groups in the ADHD sample, likely reflecting severity differences across the different centers and not any substantial difference in the clinical presentation of ADHD. Conclusions The results replicate previous studies of a model with a unitary ADHD component and separable specific traits of inattention and hyperactivity/impulsivity. The unique contribution of this study was finding support for this model across a large developmental and multinational/multicultural sample and its invariance across ages. PMID:22084976

While research regarding emotion recognition in ASD has focused primarily on social cues, musical stimuli also elicit strong emotional responses. This study extends and expands the few previous studies of response to music in ASD, measuring both psychophysiological and behavioral responses in younger children (ages 8-11) as well as older adolescents (ages 16-18). Compared to controls, the ASD group demonstrated reduced skin conductance response to music-evoked emotion. Younger groups, regardless of diagnosis, showed greater physiological reactivity to scary stimuli than to other emotions. There was a significant interaction of age group and diagnostic group in identifying scary music stimuli, possibly evidencing disrupted developmental trajectories in ASD for integrating physiological and cognitive cues that may underlie symptoms of anxiety.

Little is known about the prevalence and phenotype of fetal alcohol syndrome (FAS) or spectrum disorders (FASD) in Korea. This study was performed to describe the distribution of alcohol-related physical features in a genetically homogeneous sample of children and adolescents in institutional settings in Korea. Children and adolescents receiving services in one of seven institutions in Seoul, Korea were screened for growth deficiency. Those who screened positive were assessed using a structured protocol for the key cardinal features of FAS, and for 11 additional alcohol-related dysmorphologic features. Based on these findings, children and adolescents were categorized as FAS, Deferred (some characteristic features of FAS), and No FAS. Groups were compared on the prevalence of specific additional features and number of additional features, stratified by gender and age. Of 307 children and adolescents screened, 87 received the dysmorphology evaluation. Thirteen were classified as FAS, 44 Deferred, and 30 No FAS. The frequency of 10 of the 11 additional alcohol-related features did not differ significantly by FAS category. Palmar crease abnormalities were more common in FAS (53.8%) than in the Deferred category (25.0%) or the No FAS category (6.7%) (P = 0.003). A high prevalence across all groups was found for midfacial hypoplasia and epicanthal folds, whereas only one child exhibited ptosis. This study suggests that an FASD phenotype variant related to ethnic differences in the range of defects specific to prenatal alcohol exposure may be present in the Korean population. PMID:26384109

In the present study, a computerized test was used to compare the attention level of a group of healthy older participants aged 75 with that of a group of students aged 31. The second part of the study examined only the older participants and sought to discover how three measures of lifestyle were related to measures of attention. The results showed that the young group performed better on measures of attention. No differences between the two age groups were found on measures of impulsivity and on four measures of sustained attention. A discriminant function analysis found that reaction time and standard deviation of reaction time can explain 87.50% of the variance in both groups. The older participants' answers to the lifestyle questions showed that variables of attention correlated significantly with time spent watching television and reading. The results indicate that attention level declines with age; however, no decline was observed on measures of impulsivity and sustained attention. PMID:26537543

This study explored the prevalence of risk behaviors (excessive alcohol use, illegal drug use, heavy smoking, reduced sleep, overweight, underweight, sedentary behavior, high use of Internet/TV/videogames for reasons not related to school or work, and truancy), and their association with psychopathology and self-destructive behaviors, in a sample of 12,395 adolescents recruited in randomly selected schools across 11 European countries. Latent class analysis identified three groups of adolescents: a low-risk group (57.8%) including pupils with low or very low frequency of risk behaviors; a high-risk group (13.2%) including pupils who scored high on all risk behaviors, and a third group ("invisible" risk, 29%) including pupils who were positive for high use of Internet/TV/videogames for reasons not related to school or work, sedentary behavior and reduced sleep. Pupils in the "invisible" risk group, compared with the high-risk group, had a similar prevalence of suicidal thoughts (42.2% vs. 44%), anxiety (8% vs. 9.2%), subthreshold depression (33.2% vs. 34%) and depression (13.4% vs. 14.7%). The prevalence of suicide attempts was 5.9% in the "invisible" group, 10.1% in the high-risk group and 1.7% in the low-risk group. The prevalence of all risk behaviors increased with age and most of them were significantly more frequent among boys. Girls were significantly more likely to experience internalizing (emotional) psychiatric symptoms. The "invisible" group may represent an important new intervention target group for potentially reducing psychopathology and other untoward outcomes in adolescence, including suicidal behavior.

Estimation of age-group differences and intra-individual change across distinct developmental periods is often challenged by the use of age-appropriate (but non-parallel) measures. We present a short version of the Behavior Assessment System (Reynolds & Kamphaus, 1998), Parent Rating Scales for Children (PRS-C) and Adolescents (PRS-A), which uses only their common-items to derive estimates of the initial constructs optimized for developmental studies. Measurement invariance of a three-factor model (Externalizing, Internalizing, Adaptive Skills) was tested across age-groups (161 mothers using PRS-C; 200 mothers using PRS-A) and over time (115 mothers using PRS-C at baseline and PRS-A five years later) with the original versus short PRS. Results indicated that the short PRS holds a sufficient level of invariance for a robust estimation of age-group differences and intra-individual change, as compared to the original PRS, which held only weak invariance leading to flawed developmental inferences. Importance of test-content parallelism for developmental studies is discussed. PMID:25045196

Binks & Jeffries and Malo et al. have recently reported Li depletion boundary (LDB) ages for the β Pictoris moving group (BPMG) which are twice as old as the oft-cited kinematic age of ˜12 Myr. In this study, we present (1) a new evaluation of the internal kinematics of the BPMG using the revised Hipparcos astrometry and best available published radial velocities, and assess whether a useful kinematic age can be derived, and (2) derive an isochronal age based on the placement of the A-, F-, and G-type stars in the colour-magnitude diagram (CMD). We explore the kinematics of the BPMG looking at velocity trends along Galactic axes, and conducting traceback analyses assuming linear trajectories, epicyclic orbit approximation, and orbit integration using a realistic gravitational potential. None of the methodologies yield a kinematic age with small uncertainties using modern velocity data. Expansion in the Galactic X and Y directions is significant only at the 1.7σ and 2.7σ levels, and together yields an overall kinematic age with a wide range (13-58 Myr; 95 per cent CL). The A-type members are all on the zero-age main sequence, suggestive of an age of >20 Myr, and the loci of the CMD positions for the late-F- and G-type pre-main-sequence BPMG members have a median isochronal age of 22 Myr (± 3 Myr statistical, ±1 Myr systematic) when considering four sets of modern theoretical isochrones. The results from recent LDB and isochronal age analyses are now in agreement with a median BPMG age of 23 ± 3 Myr (overall 1σ uncertainty, including ±2 Myr statistical and ±2 Myr systematic uncertainties).

Cross-sectional studies suggest that assets are associated with youth abstinence, but whether these relationships are constant across developmental age groups has not been shown. Data for this study were obtained from two independent datasets collected across a 2-year period using in-person, in-home interviews of youth (52% female; 44% Caucasian,…

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.

A steadily growing number of empirical research on cyberbullying exists retaining the traditional definition of bullying. However, whether this scientific and theoretical definition represents youths' perceptions and experiences with cyberbullying is a subject of further investigation. Scenarios of cyberbullying incidents were used and later discussed in three focus groups with 20 adolescents (55 % boys, 45 % girls, 11-16 years old). Thematic and content analyses laid focus on the following questions: (1) Which terms are used by the adolescents to describe the behaviors in the incidents? (2) What are the roles of traditional bullying definition criteria (i. e. intention, repetition, and power imbalance) and two additional cyberbullying-specific criteria (i. e. anonymity and publicity)? (3) How are the behaviors perceived in comparison to each other? Results show that German adolescents perceive "cybermobbing" as the best term to describe the presented incidents. Impersonation was not perceived as cyberbullying by the adolescents, but rather viewed as a criminal act. In addition, adolescents perceived the intent to harm, the impact on the victim, and repetition relevant for defining cyberbullying. Moreover, analyses revealed an interdependence between criteria which suggests that anonymity and publicity have an effect on the severity of the behavior, however they were not essential for the definition of cyberbullying.

This article reviews behavioral, neuropsychological, and academic outcomes of individuals with cleft across three age levels: 1) infancy/early development, 2) school age, and 3) adolescence/young adulthood. The review points out that attachment, neurocognitive functioning, academic performance/learning, and adjustment outcomes are the result of a complex interaction between biological and environmental factors and vary with developmental level, sex, and craniofacial anomaly diagnosis. The degree to which associated genetic or neurodevelopmental conditions may explain inconsistent findings is unknown and suggests the need for caution in generalizing from group data on cleft.

The perpetration of bullying is a significant issue among researchers, policymakers, and the general public. Although researchers have examined the link between bullying and subsequent antisocial behavior, data and methodological limitations have hampered firm conclusions. This study uses longitudinal data from 411 males in the Cambridge Study in Delinquent Development from ages 8 to 56 in order to examine the relationship between adolescent bullying and distinct late middle adulthood trajectories of offending, in which different groups of males follow different offending pathways. Results show that self-reported bullying predicts only certain adult offending trajectories but that the effect becomes insignificant once controls are introduced for childhood risk factors, although this may be due to the small number of the most chronic offenders. Study implications and directions for future research are noted. PMID:23224995

Previous research shows that leanness- and weight-dependent sports increase the risk of developing disturbed eating behaviour. This study investigated whether adolescent aesthetic athletes (n=68, M=14.6 years), particularly ballet dancers and figure skaters, exhibit more eating pathology compared to the general population. Furthermore, it was investigated whether sport-related factors have explanatory value for the dieting behaviour of aesthetic athletes. To asses eating pathology, reliable and valid self-report questionnaires were used including the Eating Disorder Inventory-II, the Children's Eating Disorder Examination-Questionnaire and the Dutch Eating Behaviour Questionnaire. Results show that female aesthetic athletes show more drive for thinness, features of bulimia, dieting behaviour and concerns about weight and shape compared to female adolescents from the general population. Concerning the explanation of dieting behaviour in aesthetic athletes, both sport-related factors (competition state anxiety) and general risk factors (eating concern) seem to be relevant. These results suggest that female aesthetic athletes show more disturbed eating behaviour and thoughts than female adolescents from the general population and therefore may have an enhanced risk of developing clinical eating disorders.

Studies of temperament profiles in patients with mental disorders mostly focus on emotionality-related traits, although mental illness symptoms include emotional and nonemotional aspects of behavioral regulation. This study investigates relationships between 12 temperament traits (9 nonemotionality and 3 emotionality related) measured by the Structure of Temperament Questionnaire and four groups of clinical symptoms (depression, anxiety, antisociality, and dominance-mania) measured by the Personality Assessment Inventory. The study further examines age differences in relationships among clinical symptoms and temperament traits. Intake records of 335 outpatients and clients divided into four age groups (18-25, 26-45, 46-65, and 66-85) showed no significant age differences on depression scales; however, the youngest group had significantly higher scores on Anxiety, Antisocial Behavior, Dominance, and Thought Disorders scales. Correlations between Personality Assessment Inventory and Structure of Temperament Questionnaire scales were consistent with Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, descriptors showing strong concurrent validity. Several age differences on temperament scales are also reported. Results show the benefits of differentiation between physical, social-verbal, and mental aspects of activities, as well as differentiation between dynamical, orientational, and energetic aspects in studying mental illness and temperament.

The majority of smokers begin during adolescence, a developmental period with a high susceptibility to substance abuse. Adolescents are affected differently by nicotine compared to adults, with adolescents being more vulnerable to nicotine's rewarding properties. It is unknown if the age-dependent molecular composition of a younger brain contributes to a heightened susceptibility to nicotine addiction. Nicotine, the principle pharmacological component of tobacco, binds and activates nicotinic acetylcholine receptors (nAChRs) in the brain. The most prevalent is the widely expressed α4-containing (α4*) subtype which mediates reward and is strongly implicated in nicotine dependence. Exposing different age groups of mice, postnatal day (P) 44-86 days old, to a two bottle-choice oral nicotine self-administration paradigm for five days yielded age-specific consumption levels. Nicotine self-administration was elevated in the P44 group, peaked at P54-60 and was drastically lower in the P66 through P86 groups. We also quantified α4* nAChR expression via spectral confocal imaging of brain slices from α4YFP knock-in mice, in which the α4 nAChR subunit is tagged with a yellow fluorescent protein. Quantitative fluorescence revealed age-specific α4* nAChR expression in dopaminergic and GABAergic neurons of the ventral tegmental area. Receptor expression showed a strong positive correlation with daily nicotine dose, suggesting that α4* nAChR expression levels are age-specific and may contribute to the propensity to self-administer nicotine.

The relative influence of adolescents closest friends and their friendship group on their cigarette smoking and alcohol use was investigated in a short-term, longitudinal study of 1,028 students in the 6th, 8th, and 10th grades in 2 school systems. The amount of influence over the school year was modest in magnitude and came from the closest friend for initiation of cigarette and alcohol use. Only the friendship group use predicted transition into current cigarette use, whereas only the close friend use predicted transition into current alcohol use. Both group and close friends independently contributed to the prediction of adolescents' drinking to intoxication. No difference in the amount of influence, was found between stable and unstable close friendships or friendship groups; neither grade nor gender of the adolescents related to the amount of influence.

The aim of this study was to characterize the association between problem gambling severity and multiple health, functioning and gambling variables in adolescents aged 13–18 stratified by age of gambling onset. Survey data in 1624 Connecticut high school students stratified by age of gambling onset (≤11 years vs. ≥ 12 years) were analyzed in descriptive analyses and in logistic regression models. Earlier age of onset was associated with problem gambling severity as indexed by a higher frequency of at-risk/problem gambling (ARPG). Most health, functioning and gambling measures were similarly associated with problem gambling severity in the earlier- and later-age-of-gambling-onset groups with the exception of participation in non-strategic forms of gambling, which was more strongly associated with ARPG in the earlier-onset (OR=1.74, 95%CI=[1.26, 2.39]) as compared to later-onset (OR=0.94, 95%CI=[0.60, 1.48]) group (Interaction OR=1.91, 95%CI=[1.18, 3.26]). Post-hoc analysis revealed that earlier-onset ARPG was more strongly associated with multiple forms of non-strategic gambling including lottery (instant, traditional) and slot-machine gambling. The finding that problem gambling severity is more closely associated with multiple non-strategic forms of gambling amongst youth with earlier onset of gambling highlights the relevance of these types of youth gambling. The extent to which non-strategic forms of gambling may serve as a gateway to other forms of gambling or risk behaviors warrants additional study, and efforts targeting youth gambling should consider how best to address non-strategic gambling through education, prevention, treatment and policy efforts.

Despite the relevant findings on non-average information processing rate (IPR) indicators-intelligence relation, and on age-related changes of some of these indicators during aging, the research on sex-specific age-related changes of these indicators during childhood and adolescence are lacking. In a transversal study, 1197 school children (598 girls) aged 8-18 have been individually measured on 5 IPR indicators--two averages (mean_t, median_t) and three non-averages (min_t, max_t, sd_t). The results corroborated the expected non-linear changes of average IPR indicators in the observed developmental period, whereby the sex difference in related developmental patterns was detected: marked age-related decrement in girls ceased at the age of 12, and in boys around the age of 13-14, after which progress in both sexes gradually ceased by the age of 18 and was less pronounced in girls. Generally similar non-linear age-related decrements of non-average indicators were registered, but they showed mutual intensity differences at specific ages and sex difference in developmental patterns was detected, analogously to average indicators. Systematic sex differences in the whole observed period were obtained only in two non-average indicators: girls showed minor sd_t and boys showed minor min_t. In specific age groups, a number of sex differences were obtained that are explainable by two possible mechanisms: earlier maturation in girls and sex bias of the IPR task content. The justifiability of separate, average and non-average, IPR indicators application was corroborated by their distribution form differences, by mutual, predominantly low and medium correlations, by the different intensity of their developmental changes and by their different ability to detect sex differences. For all registered phenomena, the theoretical and/or empirical explanations were offered from the domain of sex specific intellectual, motor and neural development, and it has been shown that non

Few studies have compared parent-child dietary intake among adolescents who are overweight or obese. The purpose of our study was to determine the relationship between parent-teen intake of selected dietary components among this sample. Baseline data from 165 parent and adolescent (aged 11 to 16 years) pairs who presented for a lifestyle behavior modification intervention were collected between 2010 and 2012. Parent and adolescent dietary intake (servings of fruits and vegetables [F/V]; grams of sugar; and percent energy from total fat, saturated fat, dessert/treats, sugar-sweetened beverages, and snacks) was assessed using web-based 24-hour dietary recalls. Multivariable linear and negative binomial regression models identified associations between parent and child dietary intake adjusting for relevant covariates. A large proportion of adolescents and parents did not meet dietary recommendations for F/V, total fat, and saturated fat. Parent-adolescent intake of F/V, total fat, saturated fat, sugar, sugar-sweetened beverages, and snacks were positively associated (r=0.19 to 0.37). No relationship was observed for dessert/treats. In multivariate models, significant interaction effects suggest that the parent-child association in diet was weaker for fat intake among parents with higher educational attainment (b=-.31; P<0.05) and for snacking among adolescent boys (b=-.30; P<.05). Parent intake of several dietary components important for good health, and related to obesity, was associated with adolescent intake. Helping parents improve their diet may promote improvements in their adolescent's diet and is a potential target for interventions designed to increase healthy eating among adolescents. PMID:24951436

Tobacco cessation interventions developed for Alaska Native adolescents do not exist. This study employed focus group methodology to explore preferences for tobacco cessation interventions and barriers to participation among 49 Alaska Natives (61% female) with a mean age of 14.6 (SD = 1.6) who resided in western Alaska. Using content analysis, themes from the 12 focus groups were found to be consistent across village, gender, and age groups. Program location or site (e.g., away from the village, hunting, fishing), a group-based format, and inclusion of medication and personal stories were reported to be important attributes of cessation programs. Motivators to quit tobacco were the perceived adverse health effects of tobacco, improved self-image and appearance, and the potential to be a future role model as a non–tobacco user for family and friends. Parents were perceived as potentially supportive to the adolescent in quitting tobacco. The findings will be used to develop tobacco cessation programs for Alaska Native youth. PMID:18048549

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. PMID:25280778

Therapy for transgender, transsexual, and gender variant persons has traditionally assisted individuals in the process of adjusting to their newly adopted gender role. Increasingly, younger gender variant patients,teens and preteens, present to the clinical consultation raising the need to develop therapeutic interventions that better address the psychosocial needs of minors. The Gender and Sexuality Development Program at Children's National Medical Center (CNMC) in Washington,DC (http://www.childrensnational.org/gendervariance), provides outpatient psychosocial evaluations and therapeutic services for children,adolescents, and their families.

The aim of the study is to investigate the determinants of exposure to ETS among Greek adolescents aged 11–17 years old. The GYTS questionnaire was completed by 5,179 adolescents. About 3 in 4 responders (76.8%) were exposed to ETS at home, and 38.5% were exposed to ETS outside of the home. Gender, age group, parental and close friends smoking status were significant determinants of adolescent’s exposure to ETS. The results of the study could be valuable for the implementation of public health initiatives in Greece aiming to reduce the burden of adolescent’s exposure to passive smoking. PMID:20195445

Purpose To study the population-based annual incidence rates of exudative, dry and all cases of symptomatic age-related macular degeneration (AMD) in different age and sex groups. Methods. This is a one year, prospective, population-based study on all consecutive new patients with AMD in the hospital district of Central Finland. The diagnosis was confirmed in all patients with slit lamp biomicroscopy, optical coherence tomography (OCT) using a Spectralis HRA + OCT device, and the Heidelberg Eye Explorer 220.127.116.11 program. Fluorescein angiograms were taken when needed. Results. The population-based annual incidence rates of all cases of symptomatic AMD increased from 0.03% (95% CI, 0.01-0.05%) in the age group 50-59 years to 0.82% (95% CI, 0.55-1.09%) in the age group 85-89 years and were 0.2% (95% CI, 0.17-0.24%) in exudative, 0.11% (95% CI, 0.09-0.14%) in dry, and 0.32% (95% CI, 0.28-0.36%) in all cases of AMD in the age group 60 years and older. During the next 20 years in Central Finland the population-based annual incidence rates can be estimated to increase to 0.27% (95% CI, 0.24-0.30%) in exudative, to 0.13% (95% CI, 0.11-0.15%) in dry, and to 0.41% (95% CI, 0.37-0.45%) in all cases of AMD in the age group 60 years and older. The population-based annual incidence of AMD did not show statistically significant differences between males and females (p>0.1). Conclusion: The population-based age-group specific annual incidence rates of symptomatic AMD of this study may help to plan health care provision for patients of AMD. PMID:25674187

Objective Little is known about what may distinguish effective and ineffective group interventions. Group motivational interviewing (MI) is a promising intervention for adolescent alcohol and other drug (AOD) use; however, the mechanisms of change for group MI are unknown. One potential mechanism is change talk, which is client speech arguing for change. The present study describes the group process in adolescent group MI and effects of group-level change talk on individual alcohol and marijuana outcomes. Method We analyzed 129 group session audio recordings from a randomized clinical trial of adolescent group MI. Sequential coding was performed using the Motivational Interviewing Skill Code (MISC) and the CASAA Application for Coding Treatment Interactions (CACTI) software application. Outcomes included past-month intentions, frequency, and consequences of alcohol and marijuana use, motivation to change, and positive expectancies. Results Sequential analysis indicated that facilitator open-ended questions and reflections of change talk (CT) increased group CT. Group CT was then followed by more CT. Multilevel models accounting for rolling group enrollment revealed group CT was associated with decreased alcohol intentions, alcohol use and heavy drinking three months later; group sustain talk was associated with decreased motivation to change, increased intentions to use marijuana, and increased positive alcohol and marijuana expectancies. Conclusions Facilitator speech and peer responses each had effects on change and sustain talk in the group setting, which was then associated with individual changes. Selective reflection of CT in adolescent group MI is suggested as a strategy to manage group dynamics and increase behavioral change. PMID:25365779

The purpose of the present study was to examine how peer group processes of pressure and control and individual motivations for popularity would add to, and moderate the relationship between, childhood maltreatment and risky behavior in adolescence. A total of 1558 youth (804 girls) from three high schools in Ontario, Canada (M age = 15.02 years, SD = .86) reported on their alcohol use, delinquent behavior, childhood experiences of physical and emotional maltreatment and neglect, peer group processes involving control and individual popularity motivations. Regression analyses showed that, beyond the significant contributions of childhood maltreatment, peer group control predicted risky alcohol use and delinquent behavior. Peer group control and popularity motivations exacerbated the negative effect of physical maltreatment on delinquent behavior. Boys' experiences of peer group control were more strongly linked to alcohol use and delinquent behavior than girls'. These results suggest that there is a significant window of opportunity during adolescence where the peer group context can exacerbate or buffer childhood experiences. PMID:19669904

Aim Our goal is to estimate the prevalence of obesity, glucose intolerance, hypertension, dyslipidemia, and metabolic syndrome among urban children and adolescents aged 6–19 years and to raise awareness about noncommunicable diseases (NCDs) among school children in Chennai, South India. Methods The Obesity Reduction and Awareness and Screening of Noncommunicable Diseases through Group Education project plans to reach out to children and adolescents using two approaches: the school and the community approach. The school approach aims to reach out to a representative sample of approximately 20,000 urban school children and adolescents, aged 6–19 years, covering 50 schools from all parts of Chennai. Anthropometric measures will include height, weight, waist, body fat, and blood pressure. Data on demographics, family profile, behavioral aspects, physical activity, and food pattern will be obtained by using a validated questionnaire. Awareness about metabolic NCDs like obesity and diabetes will be increased by educating the children and adolescents about healthy lifestyles. Through the community approach, 2000 children and adolescents from randomly selected residential colonies in Chennai will be screened for obesity, glucose intolerance, hypertension, dyslipidemia, and metabolic syndrome. Expected Outcomes Awareness about NCDs will be increased among children and their parents in Chennai. This study will also provide valuable epidemiological data on obesity, glucose intolerance, dyslipidemia, hypertension and metabolic syndrome in children and adolescents in urban India. PMID:20920448

Gangs and group-level processes were once central phenomena for criminological theory and research. By the mid-1970's, however, gang research was primarily displaced by studies of individual behavior using randomized self-report surveys, a shift that also removed groups from the theoretical foreground. In this project, we return to the group level to test competing theoretical claims about delinquent group structure. We use network-based clustering methods to identify 897 friendship groups in two ninth grade cohorts of 27 Pennsylvania and Iowa schools. We then relate group-level measures of delinquency and drinking to network measures of group size, friendship reciprocity, transitivity, structural cohesion, stability, average popularity, and network centrality. We find significant negative correlations between group delinquency and all of our network measures, suggesting that delinquent groups are less solidary and less central to school networks than non-delinquent groups. Further analyses, however, reveal that these correlations are primarily explained by other group characteristics, such as gender composition and socioeconomic status. Drinking behaviors, on the other hand, show net positive associations with most of the network measures, suggesting that drinking groups have higher status and are more internally cohesive than non-drinking groups. Our findings shed light on a longstanding criminological debate by suggesting that any structural differences between delinquent and non-delinquent groups may be attributable to other attributes coincidental with delinquency. In contrast, drinking groups appear to provide peer contexts of greater social capital and cohesion. PMID:21572969

We find significant negative correlations between group delinquency and all of our network measures, suggesting that delinquent groups are less solidary and less central to school networks than non-delinquent groups. Further analyses, however, reveal that these correlations are primarily explained by other group characteristics, such as gender composition and socioeconomic status. Drinking behaviors, on the other hand, show net positive associations with most of the network measures, suggesting that drinking groups have higher status and are more internally cohesive than non-drinking groups. Our findings shed light on a longstanding criminological debate by suggesting that any structural differences between delinquent and non-delinquent groups may be attributable to other attributes coincidental with delinquency. In contrast, drinking groups appear to provide peer contexts of greater social capital and cohesion. PMID:21572969

Background/objectives Significant changes have been reported in dietary habits and food availability in Iceland that would be expected to compromise selenium intake and status, especially among young people. These include substantial decreases in the consumption of fish and milk, as well as the selenium content of imported wheat. The aim of this study was to assess selenium in the diet and whole blood of adolescent girls, as well as define the most important foods contributing to intake and blood concentrations of selenium. Design The subjects were 96 randomly selected girls, aged 16–20, who answered a validated food frequency questionnaire (FFQ) for dietary assessment. Selenium intake from each food group was calculated in µg/day. Blood samples were collected for measurement of whole blood selenium. Results Mean dietary selenium was 51±25 µg/day. Milk/dairy products, including cheese, contributed 36±14% of total dietary selenium; fish 18±12%; and bread/cereal products 13±6%. Mean whole blood selenium was 117±12 µg/l (range 90–208); nearly 90% of subjects were above the optimal level of 100 µg/l. Fish and bread/cereal products were the only foods significantly correlated with selenium in blood (r=0.32; P=0.002 and r=0.22; P=0.04, respectively) while no correlation was found with milk and dairy products in spite of their greater contribution to total selenium intake. Conclusion In this population of Icelandic adolescent girls, selenium intake and status seem acceptable. Judging from associations between intake and blood levels, fish and cereals may be the most important contributors to blood selenium. PMID:22952457

Excessive Internet use and its severe form, pathological internet use, are currently increasing in many industrial nations in Asia, North America and Europe. According to recent epidemiological studies pathological internet use occurs more frequently in youth than in adults. In Germany between 4 and 6% of the adolescents use the internet in a pathological way. Only few studies have investigated therapeutic interventions and their effectiveness in affected adolescents. In this pilot study, we surveyed over a period of 15 months all minor participants (aged up to 17) of a cognitive behavioural group programme at the beginning and at the end of the treatment (pre-post design) with standardized questionnaires (CIUS, SPS-J). At the second point of measurement the adolescents (n = 18, 75 percent retention rate) reported a significantly lower severity of problematic internet use as well as reduced average usage times during the week and at the weekend. No changes were revealed in psychological well-being of the youth. The results of this pilot study indicate positive effects of a cognitive behavioural group programme with psychoeducative elements in the treatment of youth affected by pathological internet use.

Obesity is a key public health issue for US youth. Previous research with primarily white samples of youth has indicated that sexual minority females have higher body mass index (BMI) and sexual minority males have lower BMI than their same-gender heterosexual counterparts, with sexual orientation differences in males increasing across adolescence. This research explored whether gender and sexual orientation differences in BMI exist in nonwhite racial/ethnic groups. Using data from Waves I–IV (1995–2009) of the US National Longitudinal Study of Adolescent Health (N = 13,306, ages 11–34 years), we examined associations between sexual orientation and BMI (kg/m2) over time, using longitudinal linear regression models, stratified by gender and race/ethnicity. Data were analyzed in 2013. Among males, heterosexual individuals showed greater one-year BMI gains than gay males across all race/ethnicity groups. Among females, white and Latina bisexual individuals had higher BMI than same-race/ethnicity heterosexual individuals regardless of age; there were no sexual orientation differences in black/African Americans. Sexual orientation disparities in BMI are a public health concern across race/ethnicity groups. Interventions addressing unhealthy weight gain in youth must be relevant for all sexual orientations and race/ethnicities. PMID:24872890

The present study tested the independent and interactive effects of multiple group identities (i.e., American and ethnic) and racial discrimination on civic beliefs among immigrant adolescents. Seventy-seven participants completed a questionnaire during after-school programs. Ethnic identity was positively associated with civic beliefs whereas racial discrimination was negatively related to civic beliefs, and racial discrimination moderated the relationships between multiple group identities and civic beliefs. Our findings highlight the importance of studying structural and individual factors jointly in the investigation of civic beliefs among immigrant adolescents. (PsycINFO Database Record PMID:25528458
Background The teenage years are the years when adolescents seek their identity, and part of this involves experimenting with tobacco. The use of tobacco as such, and norms among their friends, is more important to the adolescents than the norms of parents when it comes to using tobacco or not. The aim was to explore the significance of using snus for adolescents, and attitudes to snus, as well as the reasons why they began using snus and what maintained and facilitated the use of snus. Methods Adolescents who use snus were interviewed in focus groups. The material was analysed using content analysis. Results Four groups of boys and one group of girls were interviewed, a total of 27 students from the upper secondary vocational program. Three themes related to the students’ opinions on and experiences of using snus were found: Circumstances pertaining to snus debut indicate what makes them start using snus. Upholding, which focuses on the problem of becoming addicted and development of identity, and approach, where the adolescents reflect on their snus habits in relation to those around them. A number of factors were described as relevant to behaviour and norm building for the development into becoming a snus user. Attitudes and actions from adults and friends as well as – for the boys – development of an identity as a man and a craftsman influenced behaviour. Conclusions The results showed that development of identity was of major importance when adolescents start using snus. The adolescents were initially unable to interpret the early symptoms of abstinence problems, but subsequently became well aware of being addicted. Once they were stuck in addiction and in the creation of an image and identity, it was difficult to stop using snus. These factors are important when considering interventions of normative changes and tobacco prevention in schools as well as among parents. PMID:23148521

The objective was to investigate how teachers' assessments of children predict life satisfaction in adolescence. This is a prospective cohort study on the population-based Northern Finland Birth Cohort 1986 (n = 8,959). Information was gathered from parents, teachers and adolescents using questionnaires at the age of 7, 8 and 15. Response rates were 80-90%. Emotional and behavioural problems were assessed with Rutter Children's Behavioural Questionnaires for teachers (RB2) and parents (RA2) during the first grade at age 8. At adolescence, self-reported life satisfaction was measured with a question including five response alternatives. According to teachers' assessments, 13.9% of the children had high emotional or behavioural problems (RB2 ≥9). These assessments predicted life dissatisfaction in adolescence (OR(crude) = 1.77; 95% CI 1.43-2.20) in several models including also health behaviour and use of psychotropic medicine. However, introducing all the significant variables in the same model, RB2 lost its significance (OR = 1.28; 0.96-1.70), but good school achievement assessed by teachers was still a significant predictor. Life satisfaction in adolescence was associated with a variety of favourable concurrent factors. In conclusion teachers' assessments of children during the first school year predicted life satisfaction in adolescence. In mental health promotion, teachers' early assessments should be utilized for the benefit of children. PMID:21789735

Background: The effect of correcting static vision on sports vision is still not clear. Aim: To examine whether sports vision (depth perception [DP], dynamic visual acuity [DVA], eye movement [EM], peripheral vision [PV], and momentary vision [MV],) were different among soft tennis adolescent athletes with normal vision (Group A), with refractive error and corrected with (Group B) and without eyeglasses (Group C). Setting and Design: A cross-section study was conducted. Soft tennis athletes aged 10–13 who played softball tennis for 2–5 years, and who were without any ocular diseases and without visual training for the past 3 months were recruited. Materials and Methods: DPs were measured in an absolute deviation (mm) between a moving rod and fixing rod (approaching at 25 mm/s, receding at 25 mm/s, approaching at 50 mm/s, receding at 50 mm/s) using electric DP tester. A smaller deviation represented better DP. DVA, EM, PV, and MV were measured on a scale from 1 (worse) to 10 (best) using ATHLEVISION software. Statistical Analysis: Chi-square test and Kruskal–Wallis test was used to compare the data among the three study groups. Results: A total of 73 athletes (37 in Group A, 8 in Group B, 28 in Group C) were enrolled in this study. All four items of DP showed significant difference among the three study groups (P = 0.0051, 0.0004, 0.0095, 0.0021). PV displayed significant difference among the three study groups (P = 0.0044). There was no significant difference in DVA, EM, and MV among the three study groups. Conclusions: Significant better DP and PV were seen among soft tennis adolescent athletes with normal vision than those with refractive error regardless whether they had eyeglasses corrected. On the other hand, DVA, EM, and MV were similar among the three study groups. PMID:26632127

Background/Aim: To establish L, M, and S parameters and z score reference for the assessment of nutrition and growth of Saudi school-age children and adolescents. Subjects and Methods: Data from the original cross-sectional study were reanalyzed. The L, M, and S parameters and z scores were calculated for weight, height and body mass index for school-age children and adolescents. Results: A total of 19,299 subjects from 5 to 18 years of age were included. All were Saudi nationals and 9,827 (50.9%) were boys. The L M S parameters and z scores for weight for age, height for age, and BMI for age for boys and girls are presented in detailed tables across the age of commonly used z scores (+3, +2, +1, 0, -1, -2, -3). Graphs corresponding to the same parameters (weight, height, and BMI) showing the main z scores across all ages from 5 to 18 years are illustrated. Conclusion: This report provides the first reference for nutritional status and growth of Saudi school-age children and adolescents. This tool is essential for more accurate assessment of growth and nutrition in various clinical conditions and research. PMID:27488329

Abstract The concept of using single criterion of normal blood pressure with systolic blood pressure (SBP) < 140 mmHg and diastolic blood pressure (DBP) < 90 mmHg for all ages is still disputable. The aim of the study is to identify the cutoff value of normotension in different age and sex groups. Totally, 127,922 (63,724 men and 64,198 women) were enrolled for the analysis. Finally, four fifths of them were randomly selected as the study group and the other one fifths as the validation group. Due the tight relationship with comorbidities from cardiovascular disease (CVD), metabolic syndrome (MetS) was used as a surrogate to replace the actual cardiovascular outcomes in the younger subjects. For SBP, MetS predicted by our equation had a sensitivity of 55% and specificity of 67% in males and 65%, 83% in females, respectively. At the same time, they are 61%, 73% in males and 73%, 86% in females for DBP, respectively. These sensitivity, specificity, odds ratio, and area under the receiver operating characteristic curve from our equations are all better than those derived from the criteria of 140/90 or 130/85 mmHg in both genders. By using the presence of MetS as the surrogate of CVD, the regression equations between SBP, DBP, and age were built in both genders. These new criteria are proved to have better sensitivity and specificity for MetS than either 140/90 or 130/85 mmHg. These simple equations should be used in clinical settings for early prevention of CVD. PMID:27057846

One of the most consistent findings in developmental criminology is the "age-crime curve"-the observation that criminal behavior increases in adolescence and decreases in adulthood. Recently, Brown and Males (Justice policy J 8:1-30, 2011) conducted an analysis of aggregate arrest, poverty, and population data from California and concluded that the widely-observed adolescent peak in rates of offending is not a consequence of developmental factors, but rather an artifact of age differences in economic status. Youngsters, they argue, offend more than adults because they are poorer than adults. The present study challenges Brown and Males' proposition by analyzing data from the National Longitudinal Study of Youth (NLSY97; N = 8,984; 51% female; 26% Black, 21% Hispanic, 52% non-Black, non-Hispanic; ages 12-18 at Wave 1), which collected measures of criminal behavior and economic status at multiple time points. Consistent with scores of other studies, we find that criminal offending peaks in adolescence, even after controlling for variation in economic status. Our findings both counter Brown and Males' claim that the age-crime curve is illusory and underscore the danger of drawing inferences about individual behavior from analysis of aggregated data.

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

Objective Depression is a common psychological problem in adolescence. Recent research suggests that group cognitive-behavioral interventions can reduce and prevent symptoms of depression in youth. Few studies have tested the effectiveness of such interventions when delivered by school teachers and counselors (as opposed to research team staff). Method We evaluated the effectiveness of the Penn Resiliency Program for adolescents (PRP-A), a school-based group intervention that targets cognitive behavioral risk factors for depression. We randomly assigned 408 middle school students (ages 10-15) to one of three conditions: PRP-A, PRP-AP (in which adolescents participated in PRP-A and parents were invited to attend a parent intervention component), or a school-as-usual control. Adolescents completed measures of depression and anxiety symptoms, cognitive style, and coping at baseline, immediately after the intervention, and at 6-month follow-up. Results PRP-A reduced depression symptoms relative to the school as usual control. Baseline levels of hopelessness moderated intervention effects. Among participants with average and high levels of hopelessness, PRP (A and AP) significantly improved depression symptoms, anxiety symptoms, hopelessness, and active coping relative to control. Among participants with low baseline hopelessness, we found no intervention effects. PRP-AP was not more effective than PRP-A alone. We found no intervention effects on clinical levels of depression or anxiety. Conclusion These findings suggest that cognitive-behavioral interventions can be beneficial when delivered by school teachers and counselors. These interventions may be most helpful to students with elevated hopelessness. PMID:22889296

Age becomes an important self-defining aspect particularly during advanced age. With increasing age, negative attributes related to age and aging become salient. Aging-related declines, losses, as well as the finitude of life seem to threaten older adults' sense of self. We hypothesize that older adults will try to avoid the negative consequences of their age group membership by distancing themselves from their age group. Study 1 (N = 544, 65% women; 18-85 years of age) examined the role of age-group identification for self-conception and self-image (subjective age and future time perspective) across the life span. Results show that weakly identified older adults feel younger than their chronological age and report a more expanded future time perspective relative to their same-age counterparts. A second experiment (N = 68, 69% women; 65-85 years of age) tested the impact of age stereotypes on older adults' level of age-group identification. Results suggest that older adults are more likely to psychologically dissociate themselves from their age group when negative age stereotypes are salient. Discussion focuses on (mal)adaptive consequences of age-group dissociation in later adulthood. PMID:21988154

Objective Alexithymia is a personality construct that inhibits and interferes with normal affect regulating abilities. The purpose of our study was to assess psychometric properties of TAS-20 in younger adolescents. Methods Data were collected from 508 younger adolescents (48.8% male and 51.2% female) with a mean age of 12.56 years (DS=0.50, range: 12-13 years). We administered the following scales: 20-Item-Toronto Alexithymia Scale. Results The confirmatory factor analysis performed on the second random subsample showed reasonable goodness-of-fit for the oblique bi-factorial model: [chi]2 (32, n=254)=54.22; p=0.008; χ2/df=1.69; NNFI=0.92; CFI=0.95; SRMR=0.05; RMSEA=0.05; 90% confidence interval=0.027-0.078. Conclusion Based on the outcomes of our research we support the idea of evaluating adolescents for alexithymia. PMID:26508961

Scurvy is caused by prolonged severe dietary deficiency of vitamin C. Being rare as compared to other nutritional deficiencies, it is seldom suspected and this frequently leads to delayed recognition of this disorder. Children with abnormal dietary habits, mental illness or physical disabilities are prone to develop this disease. The disease spectrum of scurvy is quite varied and includes dermatological, dental, bone and systemic manifestations. Subperiosteal hematoma, ring epiphysis, metaphyseal white line and rarefaction zone along with epiphyseal slips are common radiological findings. High index of suspicion, detailed history and bilateral limb radiographs aids physician in diagnosing this eternal masquerader. We searched Pubmed for recent literature (2009-2014) with search terms "scurvy" "vitamin C deficiency" "ascorbic acid deficiency" "scurvy and children" "scurvy and pediatric age group". There were a total of 36 articles relevant to pediatric scurvy in children (7 reviews and 29 case reports) which were retrieved. The review briefly recapitulates the role of vitamin C, the various disease manifestations and the treatment of scurvy to create awareness of the disease which still is reported from our country, although sporadically. The recent advances related to scurvy and its management in pediatric age group are also incorporated. PMID:25983516

Within the contemporary culture of consumption, school-aged adolescents, though neither waged nor salaried producers, are nevertheless treated by the media and the advertisers as if they are active consumers who are engaged in the project of the self. For those adolescents who lack the financial resources to 'buy into' this culture, anxiety may ensue. In order to ease this anxiety, and to acquire social status, some - not all - may make the 'rational' 'consumer' choice to engage in risky health-related behaviour. In situ ethnographic research is needed in order to complement and inform the existing survey-based evidence on the relationship between economic status and health-related behaviour among school-aged adolescents as they deal with the pressures of consumerism.

Purpose To obtain input from adolescents with HIV-1 infection to inform the design of a community-based modified directly observed therapy (MDOT) antiretroviral adherence intervention. Methods Pediatric AIDS Clinical Trials Group (PACTG) protocol 1036A conducted three focus groups with 17 adolescents aged 17 to 22 years (10 females, 65% African-American) from three geographically distinct US PACTG sites. Focus group sessions were scripted, audio-taped, and transcribed verbatim. A coding dictionary was developed and validated; Ethnograph v5.08 was used to summarize coded data across and within the three sites. Prevalent themes were identified via frequencies and are reported as percents. Results Adolescents specified: the MDOT provider should be familiar to the participant and empathic; the MDOT location should be mutually agreed upon, flexible, and private; and participant and provider communication should be bidirectional, preferably by phone. Ideally the MDOT program should be continued until adolescents independently demonstrate adherence and include a weaning phase as a test of skill-acquisition. The most commonly endorsed barrier to the proposed program was MDOT would be an invasion of privacy. Initially, following introduction to the purpose of the focus group, all but one adolescent expressed MDOT could benefit someone other than themselves; however, at conclusion of the focus group discussion, a significant shift in openness to the intervention occurred whereby 11 participants indicated they would consider participation in a MDOT program if offered. Conclusions Focus group feedback clarified the feasibility, logistics, and patient concerns about the design and implementation of a proposed MDOT intervention for adolescents with HIV-1 infection who struggle with medication adherence PMID:19167660

Mandrills are one of the few Old World primates to show scent-marking. We combined ethological and chemical approaches to improve our understanding of this behavior in 3 zoo-managed groups. We observed the olfactory behavior performed by adults and adolescents (N = 39) for 775h. We investigated the volatile components of sternal scent-marks using gas chromatography-mass spectrometry and compared volatile profiles with traits of the signaler. Males marked more than females and within each sex the frequency of scent-marking was related to age and dominance status, but alpha males scent-marked most frequently and particularly in specific areas at the enclosure boundaries. We identified a total of 77 volatile components of sternal gland secretion, including compounds functioning as male sex pheromones in other mammals, in scent-marks spontaneously released on filter paper by 27 male and 18 female mandrills. We confirmed our previous findings that chemical profiles contain information including sex, male age and rank, and we also found that odor may encode information about group membership in mandrills. Our results support the hypotheses that scent-marking signals the status of the dominant male as well as playing territorial functions but also suggest that it is part of sociosexual communication.

A substantial body of evidence documents that the frequency and intensity of posttraumatic stress disorder (PTSD) symptoms are linked to such demographic variables as female sex (e.g., Kaplow et al., 2005) and age (e.g., Meiser-Stedman et al., 2008). Considerably less is known about relations between biological sex and age with PTSD's latent factor structure. This study systematically examined the roles that sex and age may play as candidate moderators of the full range of factor structure parameters of an empirically supported five-factor PTSD model (Elhai et al., 2011). The sample included 6591 trauma-exposed children and adolescents selected from the National Child Traumatic Stress Network's Core Data Set. Confirmatory factor analysis using invariance testing (Gregorich, 2006) and comparative fit index difference values (Cheung and Rensvold, 2002) reflected a mixed pattern of test item intercepts across age groups. The adolescent subsample produced lower residual error variances, reflecting less measurement error than the child subsample. Sex did not show a robust moderating effect. We conclude by discussing implications for clinical assessment, theory building, and future research. PMID:24103907

The Autism Diagnostic Interview-Revised was used to examine diagnostic profiles and age-related changes in autism symptoms for a group of verbal children and adolescents with FXS, with and without autism. After controlling for nonverbal IQ, statistically significant between-group differences for lifetime and current autism symptoms were found for the Communication and Restricted Interests/Repetitive Behaviors domains, but not the Reciprocal Social Interaction domain. Effect sizes for differences in Reciprocal Social Interaction also were smaller than effect sizes for the other domains with one exception. Overall, severity of autism symptoms improved with age for all participants, with the least improvement noted for Restricted Interests and Repetitive Behaviors. FMRP did not account for unique variance in autism symptoms over and above nonverbal IQ. PMID:20567604

This study aimed to (i) assess the prevalence and perceived need for treatment of TMD pain, and its association with socio-economic factors and gender, in adolescents in Xi᾽an, Shaanxi Province, China, and (ii) compare the prevalence and association with gender of TMD pain in Xi᾽an to an age-matched Swedish population. We surveyed Chinese adolescents aged 15 to 19 years in Xi'an, China (n = 5524), using a questionnaire with two-stage stratified sampling and the school as the sampling unit. The study included second-year students at selected high schools. It also included an age-matched Swedish population (n = 17 015) surveyed using the same diagnostic criteria for TMD pain as that used in the Chinese sample. The survey found TMD pain in 14·8% (n = 817) of the Chinese sample and 5·1% (n = 871) of the Swedish sample (P < 0·0001). Girls had significantly more TMD pain than boys in both the Chinese (P < 0·05) and Swedish (P < 0·001) samples. TMD pain increased with age in the Chinese population. Of the Chinese adolescents with TMD pain, 47% reported that they felt a need for treatment. Rural schools, low paternal education levels, poverty, living outside the home, poor general and oral health, and dissatisfaction with teeth all showed significant positive correlations with TMD pain. Prevalence of TMD pain in Chinese adolescents was significantly higher than in the Swedish sample. PMID:26538188

Prospective longitudinal data from over 14,000 youth residing in 28 communities in the rural United States were analyzed to examine the emergence of mixed-sex friendship groups in early adolescence. Youth were surveyed on 5 occasions between fall of 6th grade and spring of 9th grade. At each assessment, youth reported the names of up to 7 same-grade friends and described patterns of alcohol use, cigarette use, and delinquency. Approximately 800-900 friendship groups (M = 10.5 members) were identified at each assessment and categorized in terms of gender composition (all-girl, mostly-girl, mixed-sex, mostly-boy, all-boy). The proportion of groups categorized as mixed-sex increased with grade level (10% in 6th grade, 22% in 9th grade), but gender-homogenous groups predominated at all grade levels (76% in 6th grade, 51% in 9th grade). Mixed-sex groups were slightly larger than all-girl groups but the same size as all-boy groups. All-girl groups had the highest levels of tight-knittedness (i.e., density, reciprocity, and transitivity), with mixed-sex groups having the lowest levels and all-boy groups having intermediate levels. After controlling for demographic factors, future mixed-sex group membership was predicted by lower popularity, higher levels of delinquency, and lower levels of alcohol use; mixed-sex friendship group membership was associated with increased likelihood of cigarette use. Results are partially consistent with Dunphy's (1969) classic account of the emergence of mixed-sex groups in adolescence, but suggest that in early adolescence, mixed-sex group affiliation is significantly associated with deviant behavior and peripheral social status, not with popularity.

We prospectively assessed the (1) frequency and socio-economic correlates of takeaway food consumption during adolescence; and (2) association between frequent takeaway food consumption with intakes of major food groups and anthropometric measures and blood pressure (BP). In total, 699 Sydney schoolchildren (380 girls and 319 boys) who had dietary data at both 12 and 17 years of age were included for analyses. Takeaway food consumption was self-reported and based on a single question. Anthropometric measures and BP were collected. The proportion of participants who ate takeaway foods once per week or more increased significantly over 5 years from the age of 12 to 17 years: 35·5-44·1 % (P<0·0001). In total, 12-year-old girls compared with boys had reduced odds of takeaway foods once per week or more at the age of 17 years (P=0·01), multivariable-adjusted OR 0·63 (95 % CI 0·44, 0·90). In total, 12-year-old children who ate takeaway foods once per week or more had significantly lower mean fruit (220·3 v. 253·0 g/d; P=0·03) and vegetable consumption (213·2 v. 247·7 g/d; P=0·004), 5 years later (at 17 years of age). Frequent takeaway food consumption at the age of 12 years was not associated with anthropometric indices and BP at the age of 17 years. Consumption of takeaway foods became more frequent during adolescence, particularly among boys, and it was associated with reduced intake of fruits and vegetables. PMID:27046032

Epidemiological studies in high income countries suggested that a big proportion of the population in Europe and America report adverse reactions to food. Self-reported prevalence of food allergy varied from 1.2% to 17% for milk, 0.2% to 7% for egg, 0% to 2% for peanuts and fish, 0% to 10% for shellfish, and 3% to 35% for any food. The aim of our study was to report the prevalence of self-reported food allergy in the different age groups of Georgian population and to reveal the most common self-reported food allergens. ISAAC phase III study methodology and questionnaires were used for data collection. Questions about food allergy were added to the survey and involved questions about self-reported food allergy. 6-7 years old 6140 children (response rate-94,5%) and 13-14 years old 5373 adolescents (response rate-86,9%) from two locations of Georgia, Tbilisi and Kutaisi were surveyed. 500 randomly assessed adults from Tbilisi aged 18 years and older were added later (response rate-97,6%). Findings revealed that self-reported food allergy among 6-7 years old age group and 13-14 years old age were almost the same (15,7% and 15,9% correspondingly) and slightly lower in adult population - 13,9%. Study revealed, that hen's egg was the commonest implicated food for 6-7 years age group, hazel nut - for 13-14 years old age group followed by hen's egg. Walnut and hazel nut were most reported foods for adult population. The findings also revealed that food allergy is one of the most important risk factor for symptoms associated with asthma (OR-3,05; 95%CI 2.50-3.74), rhinoconjunctivitis (OR-2,85; 95%CI 2.24-3.64) and eczema (OR-5,42; 95%CI 4.08-7.18) in childhood. The data has provided the first epidemiological information related to food allergy among children and adults in Georgia. Results should serve as baseline information for food allergy screening, diagnosis and treatment. Our findings can also inform the public health officials on the disease burden and may offer some

We investigated the relationship between group identification (with the family, school, and friendship groups) and adolescent health behaviour (smoking, binge drinking, and cannabis use). 1,111 students from 4 Scottish secondary (high) schools completed a questionnaire which included measures of group identification, group contact, health behaviours, and demographic variables. We found that identification with the family and school groups predicted reduced odds of substance use, whereas identification with the friend group predicted increased odds of substance use. Furthermore, the greater the number of social groups with which the participant strongly identified, the lower the odds that he/she participated in negative health behaviours. In contrast, merely having contact (rather than identifying strongly) with these groups increased the odds of participation in these behaviours. We suggest that group identification influences behaviour to the extent that it encourages adherence to group norms. PMID:26947262

This study extends the determinants of parenting model to adolescent mothers by examining how adolescent mother–grandmother psychological conflict and perceptions of infant fussiness from birth through age 2 years relate to children's problem behaviors at age 7. Participants were 181 adolescent mother, child, and grandmother triads living in multigenerational households and recruited at delivery. Psychological conflict was characterized by two stable trajectories. In multivariate models that included maternal depression, both psychological conflict and perceptions of infant fussiness predicted externalizing behavior at age 7. Perceptions of infant fussiness, but not psychological conflict, predicted internalizing behavior at age 7. PMID:21534055

Longitudinal links between early childhood temperament, maternal sensitivity, and adolescents' adjustment have been proposed and found in several longitudinal studies, but the mechanisms of influence have not been explored. The authors examined the paths from maternal sensitivity and temperament in early childhood to adolescents' prosocial, aggressive, and delinquent behaviors via childhood social behaviors and peer group affiliation. Data at 54 months, Grade 3 (M age = 9.03, SD = .31), Grade 6 (M age = 11.95, SD = .34), and Grade 9 (M age = 15.57, SD = .78) from the NICHD SECCYD longitudinal investigation of 1,364 participants (52% boys) was analyzed. Overall, results yielded evidence that maternal sensitivity and child temperament at 54 months of age predicted prosocial, aggressive, and delinquent outcomes at age 15. Affiliation with peer groups (especially with prosocial peers) and social behaviors in childhood mediated the aforementioned paths for effortful control, but not for maternal sensitivity. Discussion focuses on the implications for understanding the long-term effects of early childhood predictors on behavioral outcomes in adolescence. (PsycINFO Database Record PMID:27228452

Age-related cognitive decline is one of the major aspects that impede successful aging in humans. Environmental factors, such as chronic stress, can accelerate or aggravate cognitive deficits during aging. While there is abundant evidence that chronic stress directly affects cognitive performance, the lasting consequences of stress exposures during vulnerable developmental time windows are largely unknown. This is especially true for the adolescent period, which is critical in terms of physical, sexual, and behavioral maturation. Here we used chronic social stress during adolescence in male mice and investigated the consequences of this treatment on cognitive performance during aging. We observed a substantial impairment of spatial memory, but not other memory domains, 12 months after the end of the stress period. This hippocampus-dependent cognitive dysfunction was supported by concomitant impairment in LTP induction in CA1 neurons in 15-month-old animals. Further, we observed a decrease of hippocampal BDNF mRNA and synaptophysin immunoreactivity, suggesting plasticity and structural alterations in formerly stressed mice. Finally, we identified expression changes of specific neurotransmitter subunits critically involved in learning and memory, specifically the NMDA receptor subunit NR2B. Taken together, our results identify possible molecular mechanisms underlying cognitive impairment during aging, demonstrating the detrimental impact of stress during adolescence on hippocampus-dependent cognitive function in aged mice.

At ages 11 through 12 years, the Advisory Committee on Immunization Practices (ACIP) recommends that preteens receive 1 dose of tetanus, diphtheria, and acellular pertussis (Tdap) vaccine, 1 dose of meningococcal conjugate (MenACWY) vaccine, and 3 doses of human papillomavirus (HPV) vaccine. ACIP recommends administration of all age-appropriate vaccines during a single visit. ACIP also recommends that pre-teens and older adolescents receive an annual influenza vaccine as well as any overdue vaccines (e.g., varicella). To monitor vaccination coverage among persons aged 13-17 years, CDC analyzed data from the National Immunization Survey-Teen (NIS-Teen). This report highlights findings of that analysis. From 2011 to 2012, coverage increased for ≥1 Tdap vaccine dose (from 78.2% to 84.6%), ≥1 MenACWY vaccine dose (from 70.5% to 74.0%) and, among males, ≥1 HPV vaccine dose (from 8.3% to 20.8%). Among females, vaccination coverage estimates for each HPV vaccine series dose were similar in 2012 compared with 2011. Coverage varied substantially among states. Regarding Healthy People 2020 targets for adolescents, 36 states achieved targets for Tdap, 12 for MenACWY, and nine for varicella vaccine coverage. Large and increasing coverage differences between Tdap and other vaccines recommended for adolescents indicate that substantial missed opportunities remain for vaccinating teens, especially against HPV infection. Health-care providers should administer recommended HPV and meningococcal vaccinations to boys and girls during the same visits when Tdap vaccine is given. In addition, whether for health problems or well-checks, providers, parents, and adolescents should use every health-care visit as an opportunity to review adolescents' immunization histories and ensure that every adolescent is fully vaccinated.

Scurvy is caused by prolonged severe dietary deficiency of vitamin C. Being rare as compared to other nutritional deficiencies, it is seldom suspected and this frequently leads to delayed recognition of this disorder. Children with abnormal dietary habits, mental illness or physical disabilities are prone to develop this disease. The disease spectrum of scurvy is quite varied and includes dermatological, dental, bone and systemic manifestations. Subperiosteal hematoma, ring epiphysis, metaphyseal white line and rarefaction zone along with epiphyseal slips are common radiological findings. High index of suspicion, detailed history and bilateral limb radiographs aids physician in diagnosing this eternal masquerader. We searched Pubmed for recent literature (2009–2014) with search terms “scurvy” “vitamin C deficiency” “ascorbic acid deficiency” “scurvy and children” “scurvy and pediatric age group”. There were a total of 36 articles relevant to pediatric scurvy in children (7 reviews and 29 case reports) which were retrieved. The review briefly recapitulates the role of vitamin C, the various disease manifestations and the treatment of scurvy to create awareness of the disease which still is reported from our country, although sporadically. The recent advances related to scurvy and its management in pediatric age group are also incorporated. PMID:25983516

Objective To evaluate the effect of menarche before 11 years of age on the incidence of wheezing/asthma in girls 11 to 18 years of age. Methods The study sample comprised 1,350 girls from a birth cohort that started in 1993 in the urban area of the city of Pelotas, southern Brazil; this cohort was followed until 18 years of age. We assessed wheezing by the question, “Have you ever had wheezing in the chest at any time in the past?,” from the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire. Early menarche was defined as occurring before 11 years of age. We estimated the cumulative incidence of wheezing excluding from the analysis all those participants who reported wheezing before age of 11 years. We performed the chi-square test to assess the association between ever wheezing and independent variables. Poisson regression models with robust variance were used to estimate cumulative incidence ratios. Results The average age at menarche in the cohort girls was 12 years (95% CI: 11.1–12.1). The prevalence of early menarche before 11 years of age was 11% (95% CI: 9.7–12.3). The cumulative incidence of wheezing from 11 to 18 years of age was 33.5% (95% CI: 30.9– 36.0). The crude association between ever wheezing in adolescence and early menarche before age 11 was 1.19 (95% CI: 0.96–1.48). After adjusting for early childhood and contemporaneous variables, no significant association for early menarche before 11 years of age and wheezing during adolescence was found (CIR: 1.18; CI95%: 0.93-1.49). Conclusion Early menarche before 11 years of age is not associated with an increased risk of wheezing during adolescence. PMID:26870751

Increasingly, adolescents are growing up in multiethnic multicultural societies. While intergroup prejudice can threaten the multicultural societal cohesion, intergroup friendships are strong predictors of reduced prejudice. Thus, more research is needed to fully understand the development of intergroup friendships and their relations to less prejudicial attitudes. This study addressed two major developmental research questions: first, whether longitudinal patterns of intergroup friendships of native adolescents (i.e., whether or not a native German adolescent has a friendship with an immigrant at different points in time) relate to changes in rates of prejudice about immigrants. Second, whether these friendship patterns that unfold over time can be predicted by contact opportunities, attitudes, subjective norms, and perceived behavioral control assessed at the beginning of the study. The sample included 372 native German adolescents (14.7 years of age at first assessment, 62.3% girls) who showed one of four friendship trajectories over the three annual assessments: they either maintained, gained, never had, or lost a friendship with an outgroup peer. In particular, results showed that adolescents who gained an intergroup friendship over the three time points showed a significant decrease in negative prejudice over the study. All four theorized predictors contributed to explain friendship trajectory membership. Generally, adolescents with many opportunities for contact, positive attitudes about contact, perceived positive social norms for contact, and high levels of behavioral control (self-efficacy) were more likely to maintain a friendship with an outgroup member than to follow any of the three other friendship trajectories (gain, lost, or never had). The pattern of predictions differed, however, depending on the specific pairs of friendship trajectories compared. PMID:25647141

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. PMID:26662265

The intraparietal sulcus (IPS), a region in the dorsal attention network (DAN), has been implicated in multi-sensory attention and working memory. Working memory and attention develop across childhood; changes in functional connectivity within the DAN may relate to this maturation. Previous findings regarding fronto-parietal intrinsic functional connectivity age-effects were mixed. Our study aimed to circumvent limitations of previous work using a large cross-sectional sample, 183 typically developing participants 6.5-20 years, from the Autism Brain Imaging Data Exchange, and seed regions along the anterior-to-posterior axis of the IPS. These seeds, IPS0-4, were entered into functional connectivity models. Group-level models investigated differential connectivity along the IPS and relationships with age. Anterior IPS3/4 exhibited greater connectivity with sensorimotor/pre-motor regions. Posterior IPS0/1 demonstrated greater connectivity with dorsal and ventral visual regions. Positive age-effects were found between IPS3-4 and visual regions. Negative age-effects were found between IPS and superior parietal and medial orbitofrontal cortices. Follow-up region of interest analyses were used to estimate age-effects for DAN and anticorrelated default mode network regions. Results suggest age-effects on IPS functional connectivity are relatively modest, and may differ pre- and across-adolescence. Studying typical age-related connectivity variability within this network may help to understand neurodevelopmental disorders marked by impaired attention. PMID:25951196

Immunogenicity and safety of a recombinant, live-attenuated, tetravalent dengue disease vaccine (CYD-TDV) was evaluated in children/adolescents in Brazil. In this observer-blind, placebo-controlled, phase II single-center study, children/adolescents (ages 9–16 years) were randomized to receive CYD-TDV or placebo at 0, 6, and 12 months. Immunogenicity was assessed using a 50% plaque neutralization test. Overall, 150 participants were enrolled (CYD-TDV: N = 100; placebo: N = 50). Injection site pain and headache were the most common solicited injection site and systemic reactions. Unsolicited adverse events (AEs) and serious AEs were similar between groups. No serious AEs were vaccine-related. Geometric mean titers against all dengue virus serotypes increased with CYD-TDV vaccination and were 267, 544, 741, and 432 1/dil for serotypes 1–4, respectively, after dose 3, representing a mean fold increase from baseline of 5, 6, 6, and 20, respectively. CYD-TDV vaccination elicited a neutralizing antibody response against serotypes 1–4 and was well-tolerated in children/adolescents in a dengue-endemic region. PMID:24189367

The safety and efficacy of guanfacine extended release (up to 4 mg/day) for attention-deficit/hyperactivity disorder (ADHD) in children and adolescents aged 6-17 years is well documented. Data suggest that weight-adjusted doses of guanfacine extended release >0.08 mg/kg but ≤0.12 mg/kg, if tolerated, may provide additional clinical benefits. For many adolescents, such dosing would exceed 4 mg/day, the highest approved dose. This open-label multicenter study evaluated the safety, tolerability, and steady-state pharmacokinetics of guanfacine extended release at escalated forced doses ≤9 mg/day in adolescents (N = 31) aged 13-17 years with ADHD. Following doses of approximately 0.12 mg/kg, the highest weight group (>70-90 kg) exhibited lower mean clearance at steady-state than the lowest weight group (≥30-50 kg). Consistent with its known antihypertensive effects, guanfacine extended release was associated with dose-dependent decreases in blood pressure (BP) and heart rate (HR). The physiologic response of increased BP upon standing was blunted in a dose-related manner while the physiologic response of increased HR upon standing was not substantively affected. The most common treatment-emergent adverse events were somnolence, dizziness, and sinus bradycardia. These results, and those from prior studies, support further examination of the efficacy and safety of higher weight-adjusted doses of guanfacine extended release for ADHD. PMID:27128830

Distinct differences in the human voice emerge during adolescence, with males producing deeper and more resonant voices than females by the end of sexual maturation. Using magnetic resonance images of heads and voice recordings obtained in 532 typically developing adolescents, we investigate what might be the drivers of this change in voice, and the subjective judgment of the voice "maleness" and "femaleness". We show clear sex differences in the morphology of voice-related structures during adolescence, with males displaying strong associations between age (and puberty) and both vocal-fold and vocal-tract length; this was not the case in female adolescents. At the same time, males (compared with females) display stronger associations between age (and puberty) with both fundamental frequency and formant position. In males, vocal morphology was a mediator in the relationship between bioavailable testosterone and acoustic indices. Subjective judgment of the voice sex could be predicted by the morphological and acoustic parameters in males only: the length of vocal folds and its acoustic counterpart, fundamental frequency, is a larger predictor of subjective "maleness" of a voice than vocal-tract length and formant position.

Objective ‘Treatment-resistant depression’ is depression that does not respond to an adequate regimen of evidence-based treatment. Treatment-resistant depression frequently becomes chronic. Children with treatment-resistant depression might also develop bipolar disorder (BD). The objective of this study was to determine whether serum levels of oxytocin (OXT) in treatment-resistant depression in adolescents (TRDIA) differ from non-treatment-resistant depression in adolescents (non-TRDIA) or controls. We also investigated the relationships between serum OXT levels and the clinical symptoms, severity, and familial histories of adolescent depressive patients. Methods We measured serum OXT levels: TRDIA (n = 10), non-TRDIA (n = 27), and age- and sex- matched, neurotypical controls (n = 25). Patients were evaluated using the Children’s Depression Rating Scale-Revised (CDRS-R) and the Depression Self-Rating Scale for Children-Japanese Version (DSRS-C-J). The patients were also assessed retrospectively using the following variables: familial history of major depressive disorder and BD (1st degree or 2nd degree), history of disruptive mood dysregulation disorder, recurrent depressive disorder (RDD), history of antidepressant activation. Results Serum levels of OXT among the TRDIA and non-TRDIA patients and controls differed significantly. Interestingly, the rates of a family history of BD (1st or 2nd degree), RDD and a history of antidepressant activation in our TRDIA group were significantly higher than those of the non-TRDIA group. Conclusions Serum levels of OXT may play a role in the pathophysiology of TRDIA. PMID:27536785

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

Background Bisphenol A (BPA) is an environmental estrogen used in the manufacture of polycarbonate plastics and epoxy resins used to make food and beverage packaging. Increasing evidence suggests that BPA mimics estrogens in the body and may be associated with putative markers of breast cancer risk. Objectives We analyzed the National Health and Nutrition Examination Survey (NHANES) 2003–2010 data to investigate the association of BPA with age at menarche in adolescent girls. We hypothesized that urinary BPA, as a surrogate biomarker for BPA exposure, is associated with earlier age at menarche, and that body mass index (BMI) may modulate this association. Methods We conducted cross-sectional analyses of urinary BPA, BMI and age of menarche in a subsample of 987 adolescent girls aged 12–19, using pooled data from the 2003–2010 NHANES. Unconditional logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CI) for the association between urinary BPA and early onset of menarche, with adjustment for sampling design. We additionally assessed interaction of BPA with BMI. Results Adolescent girls with moderate BPA levels appeared to be less likely to have early onset of menarche than those with the lowest levels (OR=0.57; 95% CI=0.30, 1.08) after adjusting for age, race/ethnicity, parental education, country of birth, NHANES cycle, BMI and creatinine. BMI appeared to modify the BPA-menarche association. Conclusions Although a non-significant trend suggests increasing urinary BPA may be associated with delayed menarche in adolescent girls, these results are based on cross-sectional data. Results should be clarified in carefully designed longitudinal cohort studies. PMID:25460659

Functional MRI measured with blood oxygen dependent (BOLD) contrast in the absence of intermittent tasks reflects spontaneous activity of so-called resting state networks (RSN) of the brain. Group level independent component analysis (ICA) of BOLD data can separate the human brain cortex into 42 independent RSNs. In this study we evaluated age-related effects from primary motor and sensory, and, higher level control RSNs. One hundred sixty-eight healthy subjects were scanned and divided into three groups: 55 adolescents (ADO, 13.2 ± 2.4 years), 59 young adults (YA, 22.2 ± 0.6 years), and 54 older adults (OA, 42.7 ± 0.5 years), all with normal IQ. High model order group probabilistic ICA components (70) were calculated and dual-regression analysis was used to compare 21 RSN's spatial differences between groups. The power spectra were derived from individual ICA mixing matrix time series of the group analyses for frequency domain analysis. We show that primary sensory and motor networks tend to alter more in younger age groups, whereas associative and higher level cognitive networks consolidate and re-arrange until older adulthood. The change has a common trend: both spatial extent and the low frequency power of the RSN's reduce with increasing age. We interpret these result as a sign of normal pruning via focusing of activity to less distributed local hubs. PMID:20953235

Objective To examine the relationship between pubertal timing and physical activity. Study design A longitudinal sample of 143 adolescent girls was assessed at ages 11 and 13 years. Girls' pubertal development was assessed at age 11 with blood estradiol levels, Tanner breast staging criteria, and parental report of pubertal development. Girls were classified as early maturers (n = 41) or later maturers (n = 102) on the basis of their scores on the 3 pubertal development measures. Dependent variables measured at age 13 were average minutes/day of moderate to vigorous and vigorous physical activity as measured by the ActiGraph accelerometer. Results Early-maturing girls had significantly lower self-reported physical activity and accumulated fewer minutes of moderate to vigorous and vigorous physical activity and accelerometer counts per day at age 13 than later maturing girls. These effects were independent of differences in percentage body fat and self-reported physical activity at age 11. Conclusion Girls experiencing early pubertal maturation at age 11 reported lower subsequent physical activity at age 13 than their later maturing peers. Pubertal maturation, in particular early maturation relative to peers, may lead to declines in physical activity among adolescent girls. PMID:17961691

Adolescents with chronic pain frequently perceive a lack of support from friends. Support from a peer with a shared experience has been found to provide emotional, informational, and appraisal support. We sought to quantify the frequency with which adolescents with chronic pain want to befriend other adolescents with chronic pain, and to describe the features of these friendships. Adolescents with chronic pain who had attended a 10-week structured self-management program from 3 sites were invited to complete an online survey. Forty teens participated, 95% (n = 38) were girls; 32% (n = 13) befriended another; 52% (n = 21) were interested in befriending another but did not; 15% (n = 6) were not interested in befriending anyone. Over half (62%) of the friendships lasted at least 1 year (n = 8), but only 2 intermingled these with their regular friendships. Pain was discussed frequently during interactions. The most common reasons for not forming friendships were no time to exchange contact information during group and not having things in common. Reasons for not being interested in forming a friendship also included not having anything in common apart from pain. The majority of participants were interested in befriending another. Emotional support, by feeling understood and discussing pain without fear that the other is disinterested, was the main peer support provided. Without common interests, this form of friendship may not last and is at risk for being overly solicitous by focusing on pain. It remains unclear whether the benefits of peer support translate into improved function. PMID:26047588

With increasing age, youth with disabilities are at risk for decreased participation in leisure activities, a key component for physical and mental health. This prospective study describes changes in leisure participation and leisure preferences from school-age to adolescence in children with cerebral palsy (CP). Participants were recruited at school-age (6-12 years) for a study on participation and reassessed for a second study on adolescents (12-19 years) if >12 years. Thirty-eight children (24 males) with CP who could actively participate in the completion of the Children's Assessment of Participation and Enjoyment (CAPE) and the Preferences for Activities of Children (PAC) comprised the sample. Average time between assessments was 5.0 ± 1.3 years. Most children were ambulatory (32/38 Gross Motor Function Classification System I-II). In addition to the CAPE and PAC, children were evaluated using the Gross Motor Function Measure-66 and parents completed a socio-demographic questionnaire. Paired t-tests revealed a significant decline in leisure participation diversity and intensity (CAPE) for recreation (p<.0001), skill-based (p<.0001) and self-improvement (p<.05) activities, whereas social participation remained stable (p>.05). Diversity of active-physical activities increased modestly (p=.06) although intensity of participation in this activity domain decreased (p=.003). There was also a decline in enjoyment of leisure activities. Preferences for these leisure activities remained unchanged between school-age and adolescence, except for recreational activities. Gender, maternal education, family income and gross motor ability were not related to differences in CAPE/PAC scores with increasing age. Findings suggest that over time, children with CP's participation in leisure activities diminishes, which is of concern to their functioning and well-being. Parents may be more involved in early childhood in facilitating participation whereas in adolescence, youth may

Using the prototype willingness model (PWM) as a framework, this study sought to explore the relationship between prototype perceptions, willingness and alcohol consumption in a sample of adolescents in the United Kingdom (UK). Adolescents aged 11-17 were asked about their alcohol prototype perceptions, willingness to drink, intentions, alcohol consumption, drunkenness and harms using a cross-sectional online survey. Participants were recruited through opportunity sampling via schools and parents. The survey was completed by 178 respondents (51% female; 91 aged 11-15, 87 aged 16-17). Multivariate analysis revealed significant differences between participants aged 11-15 and 16-17 on PWM measures, even when experience with drinking was accounted for (p < .001). There were significant interactions (p < .001) between age and prototype perceptions; younger participants rated non-drinker prototypes as more favourable and more similar to the self than 16- and 17-year-old participants. Willingness and intentions interacted with age; both measures were similar in 16- and 17-year-olds, whereas younger participants scored significantly higher on willingness than intentions (p < .001). Three distinct scales of prototype descriptions were identified in principal components analysis. Characteristics related to sociability significantly predicted willingness to drink alcohol in the sample (p < .001). This study extends previous research by demonstrating that the PWM can provide a theoretical explanation of adolescent drinking in the UK. The results suggest that 11- to 15-year-olds may be the most suitable age for an intervention that targets alcohol prototypes, with a focus on sociability characteristics. PMID:26075410

Aims To examine the association of midlife report of crisis following parental death (CFPD) during childhood and adolescence, with dementia at old age. Methods In 1965, 9362 male participants of the Israel Ischemic Heart disease (IIHD) study were asked whether they have experienced CFPD (paternal or maternal) during the following ages: 0–6. 7–12. 13–18 or >18 years. Dementia was assessed over three decades later in 1889 survivors of the original cohort, 1,652 of whom were assessed for CFPD in 1965. Results Controlling for age, the estimated odds for dementia relative to individuals who reported crisis following paternal parental death (CFPR-P) at the age of 18 and above, were 3.06 (95%CI 1.42–6.61), 2.15 (95% CI 0.87–5.31) and 2.35 (95%CI 1.05–5.28) for those who reported CFPD-P at the ages of 0–6, 7–12 and 13–18 respectively. Odds for dementia were 0.60 (95% CI 0.32–1.11) for participants who reported CFPD-P at ages of 18 and above, compared to participants who did not report such a crisis. Similar results were obtained for the association of crisis reported following maternal parental death (CFPD-M) at different age groups and dementia. Conclusions CFPD during childhood is associated with increased risk for dementia in males who survived until old age. PMID:21537146
KPs in institutions, they are entitled to judicial process. Legal guidelines also provide that these adolescents have influence over their placement, access to legal counsel to challenge the conditions of their detention and regular visitation from peers, friends and family, and that all facilities be subject to frequent and periodic review by independent agencies, including community-based groups led by KPs. Conclusions Controlling international law specifies that protective interventions among KPs aged 10–17 must not only include low-threshold, voluntary services but also “protect” adolescent KPs from the harms attendant to law-enforcement-based interventions. Going forward, health practitioners must honour the right to health by adjusting programmes according to principles of minimum intervention, due process and proportionality, and duly limit juvenile justice and child protection involvement as a measure of last resort, if any.

Background: The safety and efficacy of the PrePex device for voluntary medical male circumcision (VMMC) has been demonstrated in studies in Rwanda, Uganda, and Zimbabwe, leading to the conditional prequalification of the device for use in adults. Because the majority of VMMC clients in the 14 priority countries are adolescents under 18 years, research to establish the safety and efficacy of the device for males <18 years is required. Methods: One-arm, prospective study included 402 adolescents, aged 13–17 years, using PrePex device between August 2013 and January 2014 at a VMMC centre in Harare. Endpoints are number and grade of adverse events associated with device circumcision, time to complete wound healing, client satisfaction with the procedure, and outcome. Results: The rate of medical ineligibility among adolescent males was high; 237/402 (35.9%) of study participants had to be excluded based on medical reasons. The severe/moderate adverse event rate was low at 2/402 (0.5%). No device displacements/self-removals were observed. Time to complete wound healing was shorter than in adults; 367/398 (92.2%) adolescents had completed wound healing by day 35, whereas 90% of adults had completed wound healing by day 56 as demonstrated in previous studies. Overall, adolescents were highly satisfied with the results of their circumcision. Conclusions: The study demonstrates that the PrePex device can be safely used in adolescents aged 13–17 years. The significant proportion of males opting for surgical circumcision and the high medical ineligibility suggest that surgical circumcision needs to be provided alongside PrePex services in programs targeting young age groups.

The objective of this study was to examine adolescent age and experience with drug use on stigmatizing attitudes toward drug addiction. Data were derived from the 2005 cycle of the Ontario Student Drug Use Survey. In total, 4078, 7- to 12-graders completed self-administered questionnaires that included a measure of drug abuse stigma. Results indicated that stigma scores were higher among younger than older adolescents, and the decline across age was robust, occurring among both males and females and those from rural and non-rural areas. The decline, however, was stronger among non-drug users and among those who had no close friends that use drugs. Despite the age-related decline, the level of stigma in general suggested that drug abuse stigma may continue into adulthood. Findings highlight that individual attitudes toward drug use and drug abusers are salient factors for personal drug use. Given that stigma is a barrier to treatment, but reduced stigma may encourage greater adolescent use, this study highlights the need for more in-depth studies of drug stigma. PMID:19097707

The ability to attend to one among multiple sources of information is central to everyday functioning. Just as central is the ability to switch attention among competing inputs as the task at hand changes. Such processes develop surprisingly slowly, such that even into adolescence, we remain slower and more error prone at switching among tasks compared to young adults. The amplitude of oscillations in the alpha band (~8-14 Hz) tracks the top-down deployment of attention, and there is growing evidence that alpha can act as a suppressive mechanism to bias attention away from distracting sensory input. Moreover, the amplitude of alpha has also been shown to be sensitive to the demands of switching tasks. To understand the neural basis of protracted development of these executive functions, we recorded high-density electrophysiology from school-aged children (8-12 years), adolescents (13-17), and young adults (18-34) as they performed a cued inter-sensory selective attention task. The youngest participants showed increased susceptibility to distracting inputs that was especially evident when switching tasks. Concordantly, they showed weaker and delayed onset of alpha modulation compared to the older groups. Thus the flexible and efficient deployment of alpha to bias competition among attentional sets remains underdeveloped in school-aged children. PMID:26190204

Background: Parental substance abuse confronts children with a variety of psychological, social, and behavioral problems. Children of substance abusing parents show higher levels of psychiatric disorders including anxiety and depression and exert lower levels of communication skills. Weak social skills in this group of adolescents put them at a higher risk for substance abuse. Many studies showed school based interventions such as life skill training can effective on future substance abusing in these high risk adolescences. Materials and Methods: The participants consisted of 57 middles schools girls, all living in rural areas and having both parents with substance dependency. The participants were randomly assigned to intervention (n=28) and control (n=29) groups. The data were collected before and six weeks after training in both group. The intervention group received eight sessions of group assertiveness training. Participants were compared in terms of changes in scores on the Oxford Happiness Questionnaire and the Gambrills-Richey Assertion Inventory. Results: The total score for happiness change from 43.68 ±17.62 to 51.57 ±16.35 and assertiveness score changed from 110.33±16.05 to 90.40±12.84. There was a significant difference in pretest-posttest change in scores for intervention (7.89±4.13) and control (-2.51±2.64) groups; t (55) =2.15, p = 0.049. These results suggest that intervention really does have an effect on happiness and assertiveness. Conclusion: Determining the effectiveness of these school based interventions on other life aspects such as substance abuse calls for further study on these rural adolescent girls. PMID:26383218

The Brixton Spatial Anticipation Test assesses individuals' cognitive flexibility in terms of rule detection and attainment. It has been used to assess executive functioning in both clinical and nonclinical adult samples. However, little is currently known about the suitability of this task for younger populations. The current study therefore aimed to provide an initial exploration of this task's suitability for young people. Brixton responses from a healthy sample of children and adolescents were presented to investigate performance in both rule detection and rule attainment, respectively. A convenience sample of 72 female participants (Mage = 14.95 years, SD = 1.53 years, range = 11-17 years; MIQ = 103.76, SD = 10.81) was studied. The sample was divided according to age into four groups (11-12 years, 13-14 years, 15 years, and 16-17 years) to allow for developmental trajectory. No significant age performance differences were found. Small effect sizes between age groups lend support to the null findings. The current study suggests that the Brixton task norms are suitable for use with individuals aged 11 to 17 years old. However, normative work is still needed in this area, incorporating an adult sample for comparison, to comment upon the developmental trajectory specific to this task. PMID:25928610

Fatigue is a significant problem for adolescent and young adult (AYA) Hodgkin lymphoma (HL) survivors. The relationship between exercise and fatigue is complex. This study explored the trajectory of and the relationship between exercise and fatigue over 36 months post-therapy in a cohort of 103 AYA-aged HL survivors treated on Children's Oncology Group (COG) study AHOD0031. Descriptive statistics and generalized estimating equations were used in this secondary data analysis. Exercise and fatigue improved over time but were unrelated; amount of exercise at end of therapy predicted amount of exercise at 12 (p = 0.02) and 36 (p = 0.0008) months post-therapy. PMID:26421221

Tests of interpersonal theories of depression have established that elevated depression levels among peers portend increases in individuals’ own depressive symptoms, a phenomenon known as depression socialization. Susceptibility to this socialization effect may be enhanced during the transition to adolescence as the strength of peer influence rises dramatically. Socialization of depressive symptoms among members of child and adolescent friendship groups was examined over a 1-year period among 648 youth in grades six through eight. Sociometric methods were utilized to identify friendship groups and ascertain the prospective effect of group-level depressive symptoms on youths’ own depressive symptoms. Hierarchical linear modeling results revealed a significant socialization effect and indicated that this effect was most potent for (a) girls and (b) individuals on the periphery of friendship groups. Future studies would benefit from incorporating child and adolescent peer groups as a developmentally salient context for interpersonal models of depression. PMID:21842961

Fallopian tube torsion is a rare but important cause of acute pelvic pain in young adolescent girls. It is a surgical emergency treated with either detorsion or salpingectomy. The imaging findings can be nonspecific and challenging. However, an accurate early diagnosis is essential for prompt surgical treatment. Our objective was to review whether imaging findings can be specific enough to suggest the diagnosis of tubal torsion prospectively in the appropriate clinical setting. An Institutional Review Board-approved retrospective review of our imaging database from 2005 to 2012 revealed 10 surgically proven cases of fallopian tube torsion. All cases had sonography performed; 5 cases had additional multidetector computed tomography. All 10 patients (9-17 years) presented with acute pelvic pain. Sonographic findings included dilated tubular structures in 6 of 10 cases: adjacent to a normal ipsilateral ovary in 5 of 6 and adjacent to a benign ovarian teratoma in 1. In 4 cases, no dilated tube was identified; 3 of 4 had a cystic mass separate from the ovaries, and 1 had the imaging appearance of a multicystic ovary. Computed tomographic findings in the 5 cases that underwent multidetector computed tomography included a dilated tubular structure in 3 of 5; 2 of 5 had a cystic adnexal mass identified. Although rare, tubal torsion should be considered in female adolescents with acute pelvic pain. Sonography should be the first imaging choice. When a tubular structure or a midline cystic mass associated with a normal ipsilateral ovary is noted, tubal torsion should be considered in the differential diagnosis. PMID:25154955

Tourette syndrome (TS) is a neurological disorder characterised by vocal and motor tics. It is associated with cortical-striatal-thalamic-cortical circuit [CSTC] dysfunction and hyper-excitability of cortical motor regions. TS follows a developmental time course, in which tics often become increasingly more controlled during adolescence. Importantly, however, a substantial minority of patients continue to have debilitating tics into adulthood. This indicates that there may be important differences between adult TS patients and children and adolescents with the disorder. We use TMS to examine cortical motor excitability in a sample of children, adolescents and young adults with TS. We demonstrate that, in contrast to studies of adult patients, resting motor threshold and the variability of MEP responses are increased in children with TS, while the gain of motor excitability in reduced. Importantly, we demonstrate that these differences normalise with age over adolescence. We conclude that these effects are likely due to a developmental delay in the maturation of key brain networks in TS, consistent with recent brain imaging studies of structural and functional brain connectivity. Importantly, these findings suggest that the alterations in brain network structure and function associated with TS may be quite different in children and adult patients with the condition.

Family history of lymphoid neoplasm (LN) is a strong and consistently observed Hodgkin lymphoma (HL) risk factor, although it has been only marginally examined in pediatric/adolescent patients. Here, healthy control children identified by random digit dialing were matched on sex, race/ethnicity and age to HL cases diagnosed at 0-14 years at Children's Oncology Group institutions in 1989-2003. Detailed histories were captured by structured telephone interviews with parents of 517 cases and 783 controls. Epstein-Barr virus (EBV) RNA detection was performed for 355 available case tumors. Two analytic strategies were applied to estimate associations between family cancer history and pediatric/adolescent HL. In a standard case-control approach, multivariate conditional logistic regression was used to calculate odds ratios and 95% confidence intervals (CIs). In a reconstructed cohort approach, each relative was included as a separate observation, and multivariate proportional hazards regression was used to produce hazard ratios (HRs) and 95% CIs. Using the latter, pediatric/adolescent HL was associated with a positive family history (HR = 1.20, 95% CI: 1.06-1.36), particularly early-onset cancers (HR = 1.30, 95% CI: 1.06-1.59) and those in the paternal lineage (HR = 1.38, 95% CI: 1.16-1.65), with a suggested association for LN in first-degree relatives (HR = 3.61, 95% CI: 0.87-15.01). There were no discernable patterns for EBV+ versus EBV- HL. The clustering of LN within pedigrees may signal shared genetic susceptibility or common environmental exposures. Heritable genetic risk variants have only recently begun to be discovered, however. These results are consistent with other studies and provide a compelling rationale for family-based studies to garner information about genetic susceptibility to HL. PMID:25940226

The role of prejudice and ethnic awareness in the civic commitments and beliefs about the American social contract of 1,096 (53% female) adolescents (11-18 year olds, Mean = 15) from African-, Arab-, Latino-, and European-American backgrounds were compared. Ethnic awareness was higher among minority youth and discrimination more often reported by African- and Arab-Americans. Parental admonitions against discrimination were heard by all but African Americans, Latinos and those who reported prejudice heard that it could pose a barrier. Adolescents' beliefs that America is an equal opportunity society were negatively associated with experiences of discrimination and African-Americans were least likely to believe that the government was responsive to the average person. With respect to civic goals, all youth endorsed patriotism but ethnic minorities and ethnically aware youth were more committed to advocating for their ethnic group and European-Americans were less committed than were African Americans to improving race relations.

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

Objective To examine the trend of provider-verified HPV vaccine initiation (≥1 dose) and completion (≥3 doses) among adolescent girls at the Advisory Committee on Immunization Practices (ACIP) recommended age (11-12 years). Methods We analyzed National Immunization Survey of Teens 2008-2012 data and examined the trend of provider-verified HPV vaccine initiation and completion among <13 year old girls. Results Data on age at HPV vaccine initiation and completion were available for 24,466 and 15,972 girls, respectively. The weighted proportion of girls who initiated the vaccine at <13 years of age was 14.1%, 24.1%, 35.9%, 47.7% and 55.9% in 2008, 2009, 2010, 2011 and 2012, respectively (p for trend <.001). The similar trend was also observed for mean age at HPV vaccine initiation and completion (p <.001). Conclusions Additional efforts are needed to increase HPV vaccine uptake among adolescent girls as only half of them receive this vaccine at ACIP recommended age. PMID:25529289

Emotion processing deficits are prominent in schizophrenia and exist prior to the onset of overt psychosis. However, developmental trajectories of neural circuitry subserving emotion regulation and the role that they may play in illness onset have not yet been examined in patients at risk for psychosis. The present study employed a cross-sectional analysis to examine age-related functional activation in amygdala and prefrontal cortex, as well as functional connectivity between these regions, in adolescents at clinical high risk (CHR) for psychosis relative to typically developing adolescents. Participants (n=34) performed an emotion processing fMRI task, including emotion labeling, emotion matching, and non-emotional control conditions. Regression analyses were used to predict activation in the amygdala and ventrolateral prefrontal cortex (vlPFC) based on age, group, sex, and the interaction of age by group. CHR adolescents exhibited altered age-related variation in amygdala and vlPFC activation, relative to controls. Controls displayed decreased amygdala and increased vlPFC activation with age, while patients exhibited the opposite pattern (increased amygdala and decreased vlPFC activation), suggesting a failure of prefrontal cortex to regulate amygdala reactivity. Moreover, a psychophysiological interaction analysis revealed decreased amygdala-prefrontal functional connectivity among CHR adolescents, consistent with disrupted brain connectivity as a vulnerability factor in schizophrenia. These results suggest that the at-risk syndrome is marked by abnormal development and functional connectivity of neural systems subserving emotion regulation. Longitudinal data are needed to confirm aberrant developmental trajectories intra-individually and to examine whether these abnormalities are predictive of conversion to psychosis, and of later deficits in socioemotional functioning.

Research on intimate partner violence (IPV) has evolved over the last decade with increasing interest in how IPV develops over adolescence and young adulthood. Studies examining patterns of IPV over time have generally focused on victimization with less attention to temporal shifts in perpetration. While it is generally assumed that IPV peaks during young adulthood, this has not been empirically verified and documented. Additionally, prior longitudinal analyses of IPV have focused on identifying trajectories and their accompanying risk factors, with less attention given to within-individual change in IPV experiences across and within relationships. Drawing on five waves of data from the Toledo Adolescent Relationships Study (TARS), we examined patterns of the perpetration of IPV among a diverse sample of adolescents and young adults (51.1% female, 63.9% non-Hispanic White, 24.6% non-Hispanic Black, 11.5% Hispanic) spanning the ages of 13–28 years (N = 1,164). Analyses demonstrated that IPV patterns deviate from the age-crime curve, with women’s involvement in IPV increasing, while their involvement in other antisocial behaviors is decreasing. Traditional behavioral and psychological risk factors (delinquency, alcohol and drug use, depressive symptoms) accounted for some of the age variation in IPV for men, but these factors did not account for age variation in IPV among women. Relationship risk factors including frequency of disagreements, trust, jealousy, validation and self-disclosure, however, accounted for substantial portions of the age-IPV perpetration relationship for male and female youth. These findings reinforce recent calls for prevention efforts that focus on the development and maintenance of healthy relationships. PMID:25081024

Abstract Background: Obsessive–compulsive disorder (OCD) is a heterogeneous disorder; therefore, there is a need for identifying more homogeneous subtypes. This study aimed to examine the clinical characteristics and comorbidity pattern of a large sample of pediatric OCD subjects, and to examine the impact of gender, age at onset, and lifetime tic disorders on the clinical presentation and comorbidity pattern. Methods: A total of 110 children and adolescents diagnosed with OCD were assessed using the Kiddle Schedule for Affective Disorders and Schizophrenia for School Age Children-Present and Lifetime Version (K-SADS-PL) for psychiatric comorbidity, and a clinical data form was filled out. The cutoff for differentiating prepubertal from adolescent onset was 11 years of age. Results: A total of 83.6% of the subjects had at least one comorbid psychiatric disorder. Oppositional defiant disorder and contamination/somatic obsessions were significantly higher in males (p=0.036 and p=0.03, respectively) than in females. Depressive disorders and religious obsessions were significantly higher in the adolescent-onset group (p=0.02, p=0.05, respectively) whereas disruptive behavior disorders were higher in the prepubertal-onset group (p=0.037). Disruptive behavior disorders were significantly more frequent in the tic (+) group than in tic (-) group (p=0.021). Conclusions: There were differences in the comorbidity pattern and clinical expression between genders and between prepubertal and adolescent-onset cases. Findings of this study supported the introduction of tic-related OCD as a specifier in Diagnostic and Statistical Manual of Mental Disorders, 5th ed. (DSM-5), and the necessity of a detailed assessment of other psychiatric disorders in youth with OCD. PMID:26091196

This study explored the prevalence of risk behaviors (excessive alcohol use, illegal drug use, heavy smoking, reduced sleep, overweight, underweight, sedentary behavior, high use of Internet/TV/videogames for reasons not related to school or work, and truancy), and their association with psychopathology and self-destructive behaviors, in a sample of 12,395 adolescents recruited in randomly selected schools across 11 European countries. Latent class analysis identified three groups of adolescents: a low-risk group (57.8%) including pupils with low or very low frequency of risk behaviors; a high-risk group (13.2%) including pupils who scored high on all risk behaviors, and a third group (“invisible” risk, 29%) including pupils who were positive for high use of Internet/TV/videogames for reasons not related to school or work, sedentary behavior and reduced sleep. Pupils in the “invisible” risk group, compared with the high-risk group, had a similar prevalence of suicidal thoughts (42.2% vs. 44%), anxiety (8% vs. 9.2%), subthreshold depression (33.2% vs. 34%) and depression (13.4% vs. 14.7%). The prevalence of suicide attempts was 5.9% in the “invisible” group, 10.1% in the high-risk group and 1.7% in the low-risk group. The prevalence of all risk behaviors increased with age and most of them were significantly more frequent among boys. Girls were significantly more likely to experience internalizing (emotional) psychiatric symptoms. The “invisible” group may represent an important new intervention target group for potentially reducing psychopathology and other untoward outcomes in adolescence, including suicidal behavior.

The multiple-family group intervention is an effective, yet affordable, 8-week treatment that is conducted in a juvenile correctional institution in Alabama with adolescents who sexually offend and their families. Data from 115 incarcerated male adolescents and their male and female caregivers collected at pre-, post-, and 1-year follow-up were used to determine that problem behaviors (internalizing, externalizing) decreased over pre- and posttest and the significant decreases in maladaptive emotion regulation predicted those changes. Adolescent-reported anxiety over abandonment and attachment dependence on parents increased significantly; these changes were predicted by decreases in maladaptive emotion regulation. Linear growth models were also fit over the 3 time points and indicate decreases in adolescent problem behavior and maladaptive emotion regulation. PMID:24809985

Clients who verbalize statements arguing for change (change talk, CT) in psychotherapy are more likely to decrease alcohol and other drug use (AOD) compared to clients who voice statements in opposition of change (sustain talk, ST). Little is known about how CT and ST are expressed in groups where adolescents may vary in their AOD use severity and readiness to change. First, we examined how session content was associated with CT/ST, and then we looked at whether different subtypes of CT/ST were associated with subsequent AOD outcomes three months later. Audio recordings (N=129 sessions) of a 6-session group motivational interviewing (MI) intervention, Free Talk, were coded. Session content was not associated with CT; however, some session content was associated with higher percentages of ST (e.g., normative feedback). Subtypes of CT (Commitment and Reason) were associated with improved AOD outcomes, whereas Ability subtype remarks were related to increased marijuana use, intentions, and consequences. Findings offer helpful guidance for clinical training and narrow in on the type of CT to try to elicit in group MI sessions. Regardless of session content, adolescents can benefit from hearing CT during the group. PMID:25602608

In favour of the definition "adolescents with idiopathic scoliosis": juvenile and adolescent idiopathic scoliosis braced after ten years of age, do not show different end results. SOSORT award winner 2014
Background The most important factor discriminating juvenile (JIS) from adolescent idiopathic scoliosis (AIS) is the risk of deformity progression. Brace treatment can change natural history, even when risk of progression is high. The aim of this study was to compare the end of growth results of JIS subjects, treated after 10 years of age, with final results of AIS. Methods Design: prospective observational controlled cohort study nested in a prospective database. Setting: outpatient tertiary referral clinic specialized in conservative treatment of spinal deformities. Inclusion criteria: idiopathic scoliosis; European Risser 0–2; 25 degrees to 45 degrees Cobb; start treatment age: 10 years or more, never treated before. Exclusion criteria: secondary scoliosis, neurological etiology, prior treatment for scoliosis (brace or surgery). Groups: 27 patients met the inclusion criteria for the AJIS, (Juvenile Idiopathic Scoliosis treated in adolescence), demonstrated by an x-ray before 10 year of age, and treatment start after 10 years of age. AIS group included 45 adolescents with a diagnostic x-ray made after the threshold of age 10 years. Results at the end of growth were analysed; the threshold of 5 Cobb degree to define worsened, improved and stabilized curves was considered. Statistics: Mean and SD were used for descriptive statistics of clinical and radiographic changes. Relative Risk of failure (RR), Chi-square and T-test of all data was calculated to find differences among the two groups. 95% Confidence Interval (CI) , and of radiographic changes have been calculated. Results We did not find any Cobb angle significant differences among groups at baseline and at the end of treatment. The only difference was in the number of patients progressed above 45 degrees, found in the JIS group. The RR of progression of AJIS was, 1.35 (IC95% 0.57-3.17) versus AIS, and it wasn't statistically significant in the AJIS group, in respect to AIS group (p = 0.5338). Conclusion

The malleable nature of the self led researchers to investigate the meaning of virtual identity by exploring virtual self-representation through avatars and its association with users' identity. The present study aims to investigate the changes in virtual body-representation in adolescence related to age levels and sex and the association with adolescents' self-esteem and body esteem. Anthropometric features, body esteem and self-esteem were used to assess adolescents' body image and identity. The scoring code of the "Drawing Me" graphical test was used to evaluate the avatars. The sample is composed of 63 adolescents of different ages-early, middle and late adolescence-balanced by sex. Results show that the creation of a digital avatar changes with age and is partially associated with adolescents' perceptions in terms of body esteem and self-esteem. Moreover, the creation of avatars occurs differently for boys, who enrich their avatars with many sexual features, than for girls, who prefer to detail their avatars' clothing to enrich them. Critical reflections and implications for psychological interventions that may use avatars to investigate adolescents' identity in integration with other tools will be discussed. PMID:27376008

Redox status changes during an annual training cycle in young and adult track and field athletes and possible differences between the two age groups were assessed. Forty-six individuals (24 children and 22 adults) were assigned to four groups: trained adolescents, (TAD, N = 13), untrained adolescents (UAD, N = 11), trained adults (TA, N = 12), and untrained adults (UA, N = 10). Aerobic capacity and redox status related variables [total antioxidant capacity (TAC), glutathione (GSH), catalase activity, TBARS, protein carbonyls (PC), uric acid, and bilirubin] were assessed at rest and in response to a time-trial bout before training, at mid- and posttraining. TAC, catalase activity, TBARS, PC, uric acid, and bilirubin increased and GSH declined in all groups in response to acute exercise independent of training status and age. Training improved aerobic capacity, TAC, and GSH at rest and in response to exercise. Age affected basal and exercise-induced responses since adults demonstrated a greater TAC and GSH levels at rest and a greater rise of TBARS, protein carbonyls, and TAC and decline of GSH in response to exercise. Catalase activity, uric acid, and bilirubin responses were comparable among groups. These results suggest that acute exercise, age, and training modulate the antioxidant reserves of the body.

Sex disparities in dental caries have been observed across many populations, with females typically exhibiting higher prevalence and more affected teeth. In this study we assessed the sex disparities in two Northern Appalachian populations from West Virginia (WV, N = 1997) and Pennsylvania (PA, N = 1080) by comparing caries indices between males and females across four phases of dental development: primary dentition in children aged 1–5 years, mixed dentition in children aged 6–11 years, permanent dentition in adolescents aged 12–17 years, and permanent dentition in adults aged 18–59 years. No significant sex differences were observed for children aged 1–5 years. Contrary to national and international trends, WV girls aged 6–11 years had 1.5 fewer affected teeth than boys (p < 0.001). However, by ages 12–17, caries indices in the WV girls matched those in boys. In both WV and PA adults, women and men had similar total counts of affected teeth (i.e., DMFT), although women had more dental restorations (p < 0.001) and men had more current decay (p < 0.001). These results suggest that in some Appalachian populations, young girls benefit from protection against caries that is lost during adolescence and that adult women utilize dental health care to a greater degree than men.

Electronic media have often been considered to have a negative impact on the sleep of children and adolescents, but there are no comprehensive reviews of research in this area. The present study identified 36 papers that have investigated the relationship between sleep and electronic media in school-aged children and adolescents, including television viewing, use of computers, electronic gaming, and/or the internet, mobile telephones, and music. Many variables have been investigated across these studies, although delayed bedtime and shorter total sleep time have been found to be most consistently related to media use. A model of the mechanisms by which media use may affect sleep is presented and discussed as a vehicle for future research. PMID:20673649

Characterizing brain maturation in adolescents with disruptive behavior disorders (DBDs) may provide insight into the progression of their behavioral deficits. Therefore, this study examined how age and executive functioning were related to structural neural characteristics in DBD. Thirty-three individuals (aged 13-17) with a DBD, along with a matched control sample, completed neuropsychological testing and underwent magnetic resonance imaging (MRI) to measure gray matter volume and microstructural white matter properties. Voxel-based morphometry quantified gray matter volume, and diffusion tensor imaging measured fractional anisotropy (FA) in white matter tracts. In the anterior cingulate, gray matter volume decreased with age in healthy controls but showed no such change in the DBD sample. In the corpus callosum and superior longitudinal fasciculus (SLF), FA increased with age in the control sample significantly more than in the DBD sample. Executive functioning, particularly working memory, was associated with SLF FA bilaterally. However, the relationship of SLF FA to working memory performance was weaker in the DBD sample. These data suggest that youth with DBD have altered brain development compared with typically developing youth. The abnormal maturation of the anterior cingulate and frontoparietal tracts during adolescence may contribute to the persistence of behavioral deficits in teens with a DBD. PMID:25533028

OBJECTIVE To compare serum cystatin C levels, a novel biomarker of renal function, in adolescents with and without type 1 diabetes and to determine what factors affect cystatin C levels. RESEARCH DESIGN AND METHODS Cystatin C was measured in youth 12–19 years of age with (n = 259, diabetes duration 9 ± 3 years, HbA1c 8.9 ± 1.6%) and without diabetes (n = 78). Data were compared by diabetes status, and linear regression was used to determine factors affecting cystatin C. RESULTS Cystatin C (0.698 ± 0.083 vs. 0.688 ± 0.127 mg/L, P = 0.40) was similar by diabetes status. In multiple linear regression, cystatin C was associated with age and serum creatinine in nondiabetic subjects and sex, age, and serum creatinine in subjects with diabetes (P < 0.05). CONCLUSIONS These data suggest sex differences and age-related changes in cystatin C in adolescents with type 1 diabetes. An understanding of these changes is needed to determine the potential role of cystatin C as a marker of renal function in this population. PMID:21926294

The ability to regulate temptation and manage appetitive cravings is an important aspect of healthy adolescent development, but the neural systems underlying this process are understudied. In the present study, 60 healthy females evenly distributed from 10 to 23years of age used reappraisal to regulate the desire to consume personally-craved and not craved unhealthy foods. Reappraisal elicited activity in common self-regulation regions including the dorsal and ventral lateral prefrontal cortex (specifically superior and inferior frontal gyri), dorsal anterior cingulate cortex, and inferior parietal lobule. Viewing personally-craved foods (versus not craved foods) elicited activity in regions including the ventral striatum, as well as more rostral and ventral anterior cingulate cortex extending into the orbitofrontal cortex. Age positively correlated with regulation-related activity in the right inferior frontal gyrus, and negatively correlated with reactivity-related activity in the right superior and dorsolateral prefrontal cortices. Age-adjusted BMI negatively correlated with regulation-related activity in the predominantly left lateralized frontal and parietal regions. These results suggest that the age-related changes seen in the reappraisal of negative emotion may not be as pronounced in the reappraisal of food craving. Therefore, reappraisal of food craving in particular may be an effective way to teach teenagers to manage cravings for other temptations encountered in adolescence, including alcohol, drugs, and unhealthy food.

Reliabilities for the Raven Colored Progressive Matrices Test (CPM) are reported for three age groups (ages 5 1/2- 6 1/2, 6 1/2-7 1/2, and 7 1/2-8 1/2 years) and three ethnic groups (Anglo, Black, and Hispanic). Results indicate CPM is not equally reliable for all age groups, but appears equally reliable for the three ethnic groups. (Author)
The third versions of the guideline for treatment of people with gender identity disorder (GID) of the Japanese Society of Psychiatry and Neurology does not include puberty-delaying hormone therapy. It is recommended that feminizing/masculinizing hormone therapy and genital surgery should not be carried out until 18 year old and 20 year old, respectively. On the other hand, the sixth (2001) and the seventh (2011) versions of the standards of care for the health of transsexual, transgender, and gender nonconforming people of World Professional Association for Transgender Health (WPATH) recommend that transsexual adolescents (Tanner stage 2, [mainly 12-13 years of age]) are treated by the endocrinologists to suppress puberty with gonadotropin-releasing hormone (GnRH) agonists until age 16 years old, after which cross-sex hormones may be given. A questionnairing on 181 people with GID diagnosed in the Okayama University Hospital (Japan) showed that female to male (FTM) transsexuals hoped to begin masculinizing hormone therapy at age of 15.6 +/- 4.0 (mean +/- S.D.) whereas male to female (MTF) transsexuals hoped to begin feminizing hormone therapy as early as age 12.5 +/- 4.0, before presenting secondary sex characters. After confirmation of strong and persistent cross-gender identification, adolescents with GID should be treated with cross-gender hormone or puberty-delaying hormone to prevent developing undesired sex characters. These treatments may prevent transsexual adolescents from attempting suicide, being depressive, and refusing to attend school. Subsequent early breast and genital surgery may help being employed in desired sexuality. PMID:22844815

This study explored the attitudes, beliefs, and behaviors of rural and farm adolescents regarding hearing conservation strategies. This qualitative study took place at two high schools in rural Michigan. Twenty-five adolescents living and working on farms or living in rural areas participated in one of two focus groups. Interviews were audio-recorded and transcribed verbatim. Transcripts were coded and analyzed by two researchers and checked by an additional researcher to ensure reliability. Noise exposure was ubiquitous among participants, both in farm-related (e.g., equipment, livestock) and non-farm-related (e.g., music, firearms) activities. Perceived barriers to use of hearing protection devices outweighed perceived benefits, resulting in uncommon use of protection. When hearing protection was used, it was usually earmuffs or earplugs. Participants indicated a lack of training in noise hazards and protective strategies. Despite their acknowledged risk of hearing loss, participants did not associate their use of hearing protection today with their hearing ability later in life. Categories emerging that relate to hearing protector use included: Barriers, benefits, self-efficacy, situational influences, impersonal influences, cues to action, susceptibility, and severity. Farm and rural adolescents are at risk for noise exposure and hearing loss. The findings stress the significance of work environment and adult modeling in facilitating hearing conservation behaviors. As indicated by the youths' recommendations, school-based interventions may be an effective approach to address this health concern. Intervention studies are needed to test various approaches that can effectively promote use of hearing conservation strategies among rural and farm adolescents. PMID:25913552

Erik Erikson concluded that differences in the play constructions of young children are largely determined by psychosexual differences in the subjects and not by cultural influence. He suggested that additional observation of younger and older subjects could determine whether the differences were true for all ages or whether they were restricted…

Although group-based programs remain the most common treatment approach for adolescent smoking cessation, success rates for these programs have been relatively modest, and their reach may be limited. Web-based adjuncts may be one way to boost the efficacy and reach of group-based approaches. The purpose of this study was to evaluate the effectiveness of enhancing the American Lung Association’s Not on Tobacco program (NOT) with a Web-based adjunct (NOT Plus). Twenty-nine high schools were randomly assigned to either the NOT program alone or to the NOT Plus condition, which included access to a specially designed Web site for teens, along with proactive phone calls from the group facilitator to the participant. Self-reported smoking behavior was obtained at end-of-program and at a 3-month follow-up. Using hierarchical linear modeling, accounting for the clustering of students in schools, and controlling for student gender, grade, race, and baseline smoking rate, there was a marginally significant (p = .06) condition effect at end-of-treatment and a significant effect at 3-month follow-up (p < .05) favoring the NOT Plus condition. Approximately 57% of adolescents reported visiting the Web site, and among the NOT Plus condition, use of the Web site was associated with cessation significantly at end-of-program (p < .05), but not at 3 months. Adolescents in urban schools were more likely to access the Web site than those in rural schools. Participants who visited the Web site rated it positively on several dimensions. Reasons for not using the Web site will be discussed, as well as its value as an adjunct. PMID:17491173

Study Objectives: To investigate the efficacy of cognitive behavioral therapy for insomnia (CBTI) in adolescents. Design: A randomized controlled trial of CBTI in group therapy (GT), guided internet therapy (IT), and a waiting list (WL), with assessments at baseline, directly after treatment (post-test), and at 2 months follow-up. Setting: Diagnostic interviews were held at the laboratory of the Research Institute of Child Development and Education at the University of Amsterdam. Treatment for GT occurred at the mental health care center UvAMinds in Amsterdam, the Netherlands. Participants: One hundred sixteen adolescents (mean age = 15.6 y, SD = 1.6 y, 25% males) meeting DSM-IV criteria for insomnia, were randomized to IT, GT, or WL. Interventions: CBTI of 6 weekly sessions, consisted of psychoeducation, sleep hygiene, restriction of time in bed, stimulus control, cognitive therapy, and relaxation techniques. GT was conducted in groups of 6 to 8 adolescents, guided by 2 trained sleep therapists. IT was applied through an online guided self-help website with programmed instructions and written feedback from a trained sleep therapist. Measurements and Results: Sleep was measured with actigraphy and sleep logs for 7 consecutive days. Symptoms of insomnia and chronic sleep reduction were measured with questionnaires. Results showed that adolescents in both IT and GT, compared to WL, improved significantly on sleep efficiency, sleep onset latency, wake after sleep onset, and total sleep time at post-test, and improvements were maintained at follow-up. Most of these improvements were found in both objective and subjective measures. Furthermore, insomnia complaints and symptoms of chronic sleep reduction also decreased significantly in both treatment conditions compared to WL. Effect sizes for improvements ranged from medium to large. A greater proportion of participants from the treatment conditions showed high end-state functioning and clinically significant
The aim of the study was the analysis of RAS occurrence in the population and a comparison to other oral mucosa lesions as well as an analysis of the influence of various factors on RAS occurrence: age, social status of the subject's, parents' education, CPITN index. In the school year 1994/95 a questionnaire concerning the frequency of RAS was distributed to children and adolescents (13-18y) from two Warsaw schools and a group of soldiers of the Polish Army serving in Warsaw. Additionally, all study participants were checked towards RAS by the use of the clinical methods according to WHO methodological guidelines. The periodontal state was measured with the CPITN index described by Ainamo. The following diseases were identified: RAS, leukoplakia, lichen planus, herpes simplex and tongue lesions. The most common declared diseases of oral mucosa was RAS, which usually occurred to patients of age below 18. Clinically the most often observed diseases were oral leukoplakia in soldiers' group and RAS in both students' groups. RAS occurs more often in students, whose parents have higher education compared with persons whose parents have primary education. Parental history of disease (cases of RAS among family members) predisposes to occurrence of RAS. Stress and exhaustion are the supporting factors of RAS incidence. Furthermore, clinical periodontal status and treatment needs may also cause the increase of RAS incidence. PMID:9411506

Purpose: Lesbian, gay, bisexual, and transgender (LGBT) people are a health disparate population as identified in Healthy People 2020. Yet, there has been limited attention to how LGBT older adults maintain successful aging despite the adversity they face. Utilizing a Resilience Framework, this study investigates the relationship between physical and mental health-related quality of life (QOL) and covariates by age group. Design and Methods: A cross-sectional survey of LGBT adults aged 50 and older (N = 2,560) was conducted by Caring and Aging with Pride: The National Health, Aging, and Sexuality Study via collaborations with 11 sites across the U.S. Linear regression analyses tested specified relationships and moderating effects of age groups (aged 50–64; 65–79; 80 and older). Results: Physical and mental health QOL were negatively associated with discrimination and chronic conditions and positively with social support, social network size, physical and leisure activities, substance nonuse, employment, income, and being male when controlling for age and other covariates. Mental health QOL was also positively associated with positive sense of sexual identity and negatively with sexual identity disclosure. Important differences by age group emerged and for the old–old age group the influence of discrimination was particularly salient. Implications: This is the first study to examine physical and mental health QOL, as an indicator of successful aging, among LGBT older adults. An understanding of the configuration of resources and risks by age group is important for the development of aging and health initiatives tailored for this growing population. PMID:25213483

Studies have shown that it is necessary to create a database for dental maturity for every population and compare it to others. The present study is the first one for dental development in the Icelandic population the age range being 4-24 years. It will help in forensic dental age estimation and will also help dentists, physicians, anthropologists, archaeologists and other professionals who rely on developmental age assessment in children and adolescents. In this present retrospective cross-sectional study, dental maturity was determined in 1100 Icelandic children and adolescents from orthopantomograms (OPGs). The first 100 were used for a pilot study and the remaining 1000 for the main study. A total of 23 subjects were excluded. The sample consisted of 508 girls and 469 boys from the age of 4-24 years and a dental developmental scoring system was used as a standard for determination of dental maturity stages. A total of 200 OPGs were studied both on the left and right side and the remaining on the right side. Dental maturity was established for all teeth and both genders, when the sample permitted, from the beginning of crown formation to the root apex closure. The Cronbach's Alpha reliability test showed high reliability, R=0.982. Girls in Iceland reach dental maturity root completed (stage 10, Rc) at 17.81 years of age for the maxillary and at 18.47 years for the mandibular teeth. Boys reach dental maturity root completed (stage 10, Rc) at 18.00 years of age in the maxilla and 17.63 in the mandible. There was no significant difference between left and right side (r=0.95-1.00) and there was no gender difference, except in root formation in maxillary and mandibular canines where girls reached root completed earlier than boys. A reliable database has been established in Iceland for tooth development in the age range of 4-24 years, which is compatible with international studies. These results will help forensic odontologists and other professionals to estimate with

Osteosarcomas with lung metastases are rather heterogenous group. We aimed to evaluate the clinicopathological characteristics and outcomes of osteosarcoma patients with lung metastases and to compare the synchronous and metachronous lung metastatic groups. A total of 93 adolescent and adult patients with lung metastatic osteosarcoma, from March 1995 to July 2011, in a single center, were included. Sixty-five patients (69.9%) were male. The median age was 19 years (range, 14–74). Thirty-nine patients (41.9%) had synchronous lung metastases (Group A) and 54 patients (58.1%) had metachronous lung metastases (Group B). The 5-year and 10-year post-lung metastases overall survival (PLM-OS) was 17% and 15%, respectively. In multivariate analysis for PLM-OS, time to lung metastases (p = 0.010), number of metastatic pulmonary nodules (p = 0.020), presence of pulmonary metastasectomy (p = 0.007) and presence of chemotherapy for lung metastases (p< 0.001) were found to be independent prognostic factors. The median PLM-OS of Group A and Group B was 16 months and 9 months, respectively. In Group B, the median PLM-OS of the patients who developed lung metastases within 12 months was 6 months, whereas that of the patients who developed lung metastases later was 16 months. Time to lung metastases, number and laterality of metastatic pulmonary nodules, chemotherapy for lung metastatic disease and pulmonary metastasectomy were independent prognostic factors for patients with lung metastatic osteosarcoma. The best PLM-OS was in the subgroup of patients treated both surgery and chemotherapy. The prognosis of the patients who developed lung metastases within 12 months after diagnosis was worst.

Feelings of romanticism and self-esteem among pregnant adolescents, adolescent mothers, and a control group of nonpregnant, nonparenting adolescents were investigated. The Bachman Self-Esteem Scale (Bachman, O'Malley, & Johnston, 1978) and the Dean Romanticism Scale (Dean, 1961) were distributed to 649 U.S. female adolescents--255 pregnant adolescents, 121 adolescent mothers, and 273 teenagers in the control group. For romanticism, the results indicated a significant main effect for group (pregnant teens, teen mothers, and a control group consisting of nonpregnant, nonparenting teenagers) and ethnicity (White, Hispanic, African American, and Asian) but not for age (13 to 15 years and 16 to 19 years). The pregnant teens and teen mothers thus had a higher degree of romanticism than the control group did. For self-esteem, there was a significant main effect for race, but not for group or for age. This main effect was qualified by a significant interaction between ethnicity and age. PMID:7807975

In estimating age of juveniles and adolescents, the teeth are employed primarily because of its low variability and less affection by endocrine and nutritional status in development. Demirjian established criteria for evaluating maturity of teeth and his method has been used throughout the world. However, several studies showed the inappropriateness of Demirjian's method on populations other than the one it is based on. Consequently some researchers modified Demirjian's method using data of several different populations. Demirjian himself also published a revised method to overcome other shortcomings of his original method. The aim of this study was to test the validity of Demirjian's and the modified methods (Demirjian's revised, Willems', Chaillet's and new Korean methods) for Korean juveniles and adolescents. 1483 digital orthopantomograms which consist of 754 males and 729 females in the age range of 3-16 years were collected. New age estimation method based on Korean population data was calculated. Dental age was estimated according to each method and the validity was evaluated using the differences between chronological and dental age. The inter- and intra-observer reliability was evaluated to be excellent. Statistically significant difference was observed between chronological and dental age in all the methods for both sexes except new Korean method for both sexes and Demirjian's revised method for males. However, when analyzing absolute and squared value of difference, Willems' method was found to be most accurate followed by new Korean method with slight difference for Korean population for both sexes. In conclusion, both Willems' method and new Korean method conducted by present study were proven to be suitable for Korean population. PMID:21561728

Background Adherence with inhaled controller medications for asthma is known to be highly variable with many patients taking fewer doses than recommended for consistent control of lung inflammation. Adherence also worsens as children become teenagers, although the exact causes are not well established. Objective To use focus group methodology to examine beliefs, feelings, and behaviors about inhaled asthma controller medication in adolescents and young adults who had previously participated in a longitudinal study of asthma treatment adherence and outcome in order to develop more effective management strategies. Methods Twenty-six subjects participated in 6 focus groups comprised of 3-5 young adults (age range 12-20 years). Verbatim transcripts of these groups were analyzed using the long-table method of content analysis to identify key themes raised by participants. Results A variety of beliefs, feelings and behaviors influence the adolescent’s decision about how to use their asthma medication. Some of the adolescents understood the importance of daily medication and were committed to the treatment plan prescribed by their provider. Poorer adherence was the product of misinformation, incorrect assumptions about their asthma, and current life situations. Conclusions These results, by highlighting potential mechanisms underlying both better and worse adherence inform the development of strategies to improve adherence behavior in adolescents and young adults with asthma. Knowledge of the specific beliefs, feelings and behaviors that underlie adolescents’ use of inhaled asthma controller medication will help providers maximize treatment adherence in this notoriously difficult patient population.

Background Few lifestyle factors have been simultaneously studied and reported for Saudi adolescents. Therefore, the purpose of the present study was to report on the prevalence of physical activity, sedentary behaviors and dietary habits among Saudi adolescents and to examine the interrelationships among these factors using representative samples drawn from three major cities in Saudi Arabia. Methods This school-based cross-sectional study was conducted during the years 2009-2010 in three cities: Al-Khobar, Jeddah and Riyadh. The participants were 2908 secondary-school males (1401) and females (1507) aged 14-19 years, randomly selected using a multistage stratified sampling technique. Measurements included weight, height, sedentary behaviors (TV viewing, playing video games and computer use), physical activity using a validated questionnaire and dietary habits. Results A very high proportion (84% for males and 91.2% for females) of Saudi adolescents spent more than 2 hours on screen time daily and almost half of the males and three-quarters of the females did not meet daily physical activity guidelines. The majority of adolescents did not have a daily intake of breakfast, fruit, vegetables and milk. Females were significantly (p < 0.05) more sedentary, much less physically active, especially with vigorous physical activity, and there were fewer days per week when they consumed breakfast, fruit, milk and diary products, sugar-sweetened drinks, fast foods and energy drinks than did males. However, the females' intake of French fries and potato chips, cakes and donuts, and candy and chocolate was significantly (p < 0.05) higher than the males'. Screen time was significantly (p < 0.05) correlated inversely with the intake of breakfast, vegetables and fruit. Physical activity had a significant (p < 0.05) positive relationship with fruit and vegetable intake but not with sedentary behaviors. Conclusions The high prevalence of sedentary behaviors, physical inactivity and

The objective of this study was to assess the validity and reproducibility of a food frequency questionnaire to assess intake of the food groups included in the food guide pyramid for adolescents (FFQ-FP). The final version of the FFQ-FP consisted of 50 food items. The study was carried out with a sample of 109 adolescents over a period of four months. A 24hr recall (24hr) was conducted four times and the FFQ-FP was conducted twice. Validity was determined by comparing the second FFQ-FP and the mean of the four 24hrs, while reproducibility was verified by comparing the results of the two FFQ-FPs. Statistical analysis was carried out using medians, standard deviations, Pearson and intraclass correlations and Kappa statistics to assess concordance. Best results were achieved for the rice (including bread, grains and starches), meats and sugars groups. Weakest correlation was observed for the variable vitamin C. The validity and reproducibility of the FFQ-FP was satisfactory for most variables. PMID:24068225

The negative impact of political violence on adolescent adjustment is well-established. Less is known about factors that affect adolescents’ positive outcomes in ethnically-divided societies, especially influences on prosocial behaviors toward the outgroup, which may promote constructive relations. For example, understanding how intergroup experiences and attitudes motivate outgroup helping may foster intergroup cooperation and help to consolidate peace. The current study investigated adolescents’ overall and outgroup prosocial behaviors across two time points in Belfast, Northern Ireland (N = 714 dyads; 49% male; Time 1: M = 14.7, SD = 2.0, years old). Controlling for Time 1 prosocial behaviors, age and gender, multivariate structural equation modeling showed that experience with intergroup sectarian threat predicted fewer outgroup prosocial behaviors at Time 2 at the trend level. On the other hand, greater experience of intragroup nonsectarian threat at Time 1 predicted more overall and outgroup prosocial behaviors at Time 2. Moreover, positive outgroup attitudes strengthened the link between intragroup threat and outgroup prosocial behaviors one year later. Finally, experience with intragroup nonsectarian threat and outgroup prosocial behaviors at Time 1 was related to more positive outgroup attitudes at Time 2. The implications for youth development and intergroup relations in post-accord societies are discussed. PMID:26457005

Background: Energy drinks (EDs) have become widely popular among young adults and, even more so, among adolescents. Increasingly, they are consumed by athletes, particularly those who have just begun their sporting career. Uncontrolled and high consumption of EDs, in addition to other sources of caffeine, may pose a threat to the health of young people. Hence, our objective was to analyze the consumption of EDs among teenagers engaged in sports, including quantity consumed, identification of factors influencing consumption, and risks associated with EDs and EDs mixed with alcohol (AmEDs). Methods: The study involved a specially designed questionnaire, which was completed by 707 students, 14.3 years of age on average, attending secondary sports schools. Results: EDs were consumed by 69% of the young athletes, 17% of whom drank EDs quite often: every day or 1–3 times a week. Most respondents felt no effects after drinking EDs, but some reported symptoms, including insomnia, anxiety, tachycardia, nervousness and irritability. The major determinant of the choice of EDs was taste (47%), followed by price (21%). One in ten respondents admitted to consumption of AmEDs. Among the consequences reported were: abdominal pains, nausea, vomiting, amnesia, headache, and hangover. Conclusions: EDs consumption among adolescent athletes was relatively high. Considering the habit of AmEDs and literature data, it is worth emphasizing that it may lead to health problems in the near future, alcohol- or drug-dependence, as well as other types of risk behaviour.

The adverse impact of bullying and victimization on substance use among youth has received increasing attention. Bullying is a specific type of aggressive behavior that not only involves bullies and victims but also followers, who actively support or reinforce the bully; defenders, who intervene to defend or assist the victim; or outsiders who passively observe or ignore the bullying. Limited research to date has linked these five bullying role behaviors to substance use. The aim of this study was to investigate the relationship between each of the bullying role behaviors and adolescent alcohol and tobacco use. Participants were 1255 (748 female) students (Mage=15.3, age range: 13-17years) in Grades 9 (n=714) and 11 (n=541). Bullying role behaviors, alcohol and tobacco onset and intensity, and alcohol-related harms were assessed. Results revealed an association between pro-bullying behavior (bullying and following) and all substance use variables, and between defender behavior and smoking and alcohol-related harm. No relationship between victimization, or outsider behavior, and substance use was found after controlling for the other bullying roles. The findings highlight the complex relationship between bullying roles, alcohol and tobacco use and alcohol-related harm in adolescents. PMID:27305098

Depression is a potentially life threatening affective disorder that is highly prevalent in individuals with autism spectrum disorders (ASD). This study aimed to evaluate the feasibility, acceptability and preliminary efficacy of a cognitive behavioural intervention for depression in adolescents with ASD. Participants were randomly assigned to the intervention group, or wait-list control group. Although recruitment was extremely difficult, attendance was favourable and attrition was low, and participants reported being satisfied with the programme. No significant treatment effect was revealed on the Beck Depression Inventory or Emotion Regulation Questionnaire. However despite the small sample size (n = 20), there was a trending treatment effect measured by the Depression Anxiety Stress Scale: Depression Subscale. Limitations and areas of future research are discussed. PMID:26404701

The present study aimed to assess the skeletal and dental ages of type 1 diabetes mellitus (T1DM) patients. Therefore, panoramic and hand-wrist radiographs of 82 patients, aged between 5 and 15 years, were collected and divided into case and control groups. The case group consisted of 41 panoramic and 41 hand-wrist radiographs of T1DM patients, whereas the control group consisted of 41 panoramic and 41 hand-wrist radiographs of patients without T1DM. Skeletal age was assessed according to the method of Greulich and Pyle (1999), whereas dental age was assessed according to the method of Nolla (1960). Chi-square tests revealed no statistically significant differences between skeletal and dental ages between the case and control groups (p > 0.05). However, in the case group, the skeletal age of females was greater than that of age-matched males (p = 0.005). Considering that skeletal and dental growth of the case and control groups were closely related, clinical interventions involving orthodontics and dentomaxillofacial orthopedics should be equally performed both for healthy and specific patient groups, such as those with T1DM.

Fear or anxiety due to noise produced in the dental clinic is rated third among the reasons to avoid dental visits. The aim of the present study was to determine anxiety levels associated with noise in a dental clinic. The study was done using a survey questionnaire containing 10 questions and was divided into two parts. The first part included demographic information such as name, age, gender, and school; the second half included questions regarding patient's feelings toward noise in the dental clinic and its possible link to dental anxiety. Two-hundred and fifty children and adolescents of age group 6-15 years participated in the study. Results of the study showed that 50% of females, 29% males avoided a visit to the dentist because of anxiety and fear, 38% subjects of age group 6-11 years reported that sound of the drill makes them uncomfortable, followed by having to wait in the reception area. Gender gap was also observed with more females feeling annoyed than males on the 1-10 annoyance level scale. More than 60% felt "annoyed" to "extremely annoyed" by noise in the dental clinic. 45% of subjects preferred watching television to cope with such noise. This study concludes that the noise produced in dental clinic is anxiety provoking and significantly contributes to avoidance of dental treatment and the best way opted by the majority of subjects to overcome this anxiety was audiovisual distraction method.

Objective The establishment of an accurate understanding of one's social context is a central developmental task during adolescence. A critical component of such development is to learn how to integrate the objective evaluation of one's behavior with the social response to the latter—here referred to as social feedback processing. Case report We measured brain activity by means of fMRI in 33 healthy adolescents (12–19 years old, 14 females). Participants played a difficult perceptual game with integrated verbal and visual feedback. Verbal feedback provided the participants with objective performance evaluation (won vs. lost). Visual feedback consisted of either smiling or angry faces, representing positive or negative social evaluations. Together, the combination of verbal and visual feedback gave rise to congruent versus incongruent social feedback combinations. In addition to assessing sex differences, we further tested for the effects of age and attachment style on social feedback processing. Results revealed that brain activity during social feedback processing was significantly modulated by sex, age, and attachment style in prefrontal cortical areas, ventral anterior cingulate cortex, anterior insula, caudate, and amygdala/hippocampus. We found indication for heightened activity during incongruent social feedback processing in females, older participants, and individuals with an anxious attachment style. Conversely, we observed stronger activity during processing of congruent social feedback in males and participants with an avoidant attachment style. Conclusion Our findings not only extend knowledge on the typical development of socio-emotional brain function during adolescence, but also provide first clues on how attachment insecurities, and particularly attachment avoidance, could interfere with the latter mechanisms.

Valve repair in children is technically demanding but more desirable than valve replacement. From April 2004 to September 2005, 1 boy and 8 girls with rheumatic heart disease, aged 2-13 years (median, 9 years), underwent valve repair for isolated mitral regurgitation in 5, combined mitral and aortic regurgitation in 2, mitral stenosis in 1, and mitral regurgitation associated with atrial septal defect in 1. Chordal shortening in 7, annular plication in 6, commissurotomy in 1, reconstruction of commissural leaflets in 7 were performed for mitral valve disease. Plication and reattachment of the aortic cusps was carried out in 2 patients. Annuloplasty rings were not used. All patients survived the operation, 8 had trivial or mild residual mitral regurgitation, and 1 had trivial aortic regurgitation. Mean left atrial pressure decreased from 14 to 7 mm Hg postoperatively. During follow-up of 3-18 months, all children were asymptomatic and enjoyed normal activity. None required reoperation. In addition to chordal shortening and annular plication, reconstruction of the commissural leaflets is considered the most important aspect of valve repair. It can be achieved without annuloplasty rings, giving good early and midterm results. PMID:18381871

The present study aims to investigate the onset of dementia conditions using the Dementia Screening Questionnaire for Individuals with Intellectual Disabilities (DSQIID) scale and to identify the possible factors associated with DSQIID scores in people with Down syndrome (DS). The study population was recruited from the voluntary registry members of the Republic of China Foundation for Persons with Down syndrome; primary caregivers provided DSQIID information on 196 adolescents and adults with DS (aged 15-48 years) who were entered into the database and analyzed using SPSS 20.0 software. The results described the distribution of early-onset dementia conditions in 53 adolescents and adults with DS, and 2.6% of the subjects with DS had possible dementia (DSQIID score ≧ 20). Univariate analyses found that older age (p=0.001) and comorbid conditions (p=0.003) were significantly associated with DSQIID scores. Older subjects were more likely to have higher DSQIID scores than were younger age groups after ANOVA and Scheffe's tests. Lastly, a multiple linear regression analysis revealed that age (p<0.01), severe disability level (p<0.05) and comorbid condition (p<0.01) significantly explained 13% of the variation in DSQIID scores after adjusting for the factors of gender, education level and multiple disabilities in adolescents and adults with DS. The study highlights that future research should focus on the occurrence of dementia in people with DS and on identifying its influencing factors based on sound measurements, to initiate appropriate healthy aging policies for this group of people.

The racial/ethnic composition of the US population is shifting, with the nonwhite population growing faster than whites. We examined cannabis use disorder (CUD) prevalences and correlates in seven racial/ethnic groups. We included cannabis use (CU) prevalence as a comparison. Data were from the 2005-2011 National Surveys on Drug Use and Health (N = 394,400). Substance use among respondents aged ≥12 years was assessed by computer-assisted, self-interviewing methods. The following were included as control variables: age, sex, family income, government assistance, county type, residential stability, major depressive episode history, arrest history, nicotine dependence, alcohol disorder, and survey year. Past-year CU prevalence increased significantly from 10.45% in 2005 to 11.41-11.54% during 2009-2011. Compared with whites, mixed-race individuals had higher odds of CU; Asian Americans and Hispanics had lower odds of CU. There were no significant yearly changes in CUD prevalence in the sample during 2005-2011 (1.58-1.73%). Compared with whites, individuals who were mixed-race, black, and Native American had higher odds of CUD; Asian Americans had lower odds. In aggregate, 15.35% of past-year cannabis users met criteria for a CUD in the 12-month period. Past-year cannabis users who were black, Native American, Hispanic, or Asian American had higher odds of CUD than white users. In each racial/ethnic group, adolescent cannabis users generally showed greater odds of CUD than adult users. Behavioral health indicators (major depressive episode, arrest history, nicotine dependence, alcohol disorder) were associated with CU and CUD. In conclusion, CUD disproportionally affects nonwhite groups and youth. PMID:24342767

Body mass index (BMI) at admission is an important predictor of outcome in adolescent eating disorders. However, few studies have investigated BMI at admission, its changes in recent years, or modifying factors, such as duration of illness and age at onset in different geographical regions. Thus, this study aimed to investigate changes in BMI at admission over the past decade in one clinic, the differences in BMI between various treatment sites and the influence of duration of illness before admission and age at admission. Our sample consisted of 158 adolescent female patients with anorexia nervosa (AN) admitted between 2001 and 2009 to a major university hospital and 169 adolescent female patients recruited in a multicenter study between 2007 and 2010. We assessed the differences between departments in different regions of Germany in the multi-site sample. Changes over time in age-adjusted BMI and age at admission as well as modifying factors for age-adjusted BMI at admission, such as age at admission and duration of illness, were assessed in a representative local sample. There were no significant differences between departments in different regions of Germany. Over the course of the local study, there was a small but significant increase in the age-adjusted BMI score and absolute BMI at admission. In addition, there was a positive association between year of admission and age at admission. Older adolescents with AN had a lower age-adjusted BMI score and a longer duration of illness at the time of admission. The BMI at admission, which is one of the most important predictors of outcome in AN, has increased slightly during the past 10 years. Education strategies for parents and professionals should continue to be improved to further shorten the duration of illness before admission, especially for older adolescents. PMID:23392754

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

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. PMID:26367101

Background This study examined changes according to age group in the number of finishers and running times for athletes in female and male mountain ultramarathoners competing in the 78 km Swiss Alpine Marathon, the largest mountain ultramarathon in Europe and held in high alpine terrain. Methods The association between age and performance was investigated using analysis of variance and both single and multilevel regression analyses. Results Between 1998 and 2011, a total of 1,781 women and 12,198 men finished the Swiss Alpine Marathon. The number of female finishers increased (r2 = 0.64, P = 0.001), whereas the number of male finishers (r2 = 0.18, P = 0.15) showed no change. The annual top ten men became older and slower, whereas the annual top ten women became older but not slower. Regarding the number of finishers in the age groups, the number of female finishers decreased in the age group 18–24 years, whereas the number of finishers increased in the age groups 30–34, 40–44, 45–49, 50–54, 55–59, 60–64, and 70–74 years. In the age groups 25–29 and 35–39 years, the number of finishers showed no changes across the years. In the age group 70–74 years, the increase in number of finishers was linear. For all other age groups, the increase was exponential. For men, the number of finishers decreased in the age groups 18–24, 25–29, 30–34, and 35–39 years. In the age groups 40–44, 45–49, 50–54, 55–59, 60–64, 70–74, and 75–79 years, the number of finishers increased. In the age group 40–44 years, the increase was linear. For all other age groups, the increase was exponential. Female finishers in the age group 40–44 years became faster over time. For men, finishers in the age groups 18–24, 25–29, 30–34, 40–44, and 45–49 years became slower. Conclusion The number of women older than 30 years and men older than 40 years increased in the Swiss Alpine Marathon. Performance improved in women aged 40–44 years but

Weight dissatisfaction, body dissatisfaction, and body-image distortion measures were used with 98 fifth and eighth graders and 57 undergraduate students. Measures included the Piers-Harris Self-concept Scale and the Kids Eating Disorder Survey for the young children, the Interpersonal Behavior Survey, and a seven-item mistaken beliefs scale for the college sample. Body dissatisfaction and Body-image distortion were assessed with a figure-drawing procedure. Significant differences in both weight dissatisfaction and body dissatisfaction were found between males and females in the eighth grade and undergraduate groups. There were no significant sex differences in body-image distortion in the fifth or eighth grades, but significant differences in body-image distortion between men and women were found in the college sample. The direction of body-image distortion for both the 20 men and the 37 women was consistent with their ideal weight. In the college sample, there was a significant correlation between body-image dissatisfaction and self-confidence for the women but not for the men. PMID:9885045

Traditional burn mortality models are derived using all age groups. We hypothesized that age variably impacts mortality after burn and that age-specific models for children, adults, and seniors will more accurately predict mortality than an all-ages model. We audited data from the American Burn Association (ABA) National Burn Repository (NBR) from 2000 to 2009 and used mixed effect logistic regression models to assess the influence of age, total body surface area (TBSA) burn, and inhalation injury on mortality. Mortality models were constructed for all ages and age-specific models: children (<18 years), adults (18-60 years), and seniors (>60 years). Model performance was assessed by area under the receiver operating curve (AUC). Main effect and two-way interactions were used to construct age-group specific mortality models. Each age-specific model was compared to the All Ages model. Of 286,293 records 100,051 had complete data. Overall mortality was 4% but varied by age (17% seniors, <1% children). Age, TBSA, and inhalation injury were significant mortality predictors for all models (p<0.05). Differences in predicted mortality between the All Ages model and the age-specific models occurred in children and seniors. In the age-specific pediatric model, predicted mortality decreased with age; inhalation injury had greater effect on mortality than in the All Ages model. In the senior model mortality increased with age. Seniors had greater increase in mortality per 1% increment in burn size and 1 year increase in age than other ages. The predicted mortality in seniors using the senior-specific model was higher than in the All Ages model. "One size fits all" models for predicting burn outcomes do not accurately reflect the outcomes for seniors and children. Age-specific models for children and seniors may be advisable. PMID:24846014

Growing evidence supports the effectiveness of Trauma and Grief Component Therapy for Adolescents (TGCT-A) in reducing posttraumatic stress disorder (PTSD) symptoms and maladaptive grief (MG) reactions. This pilot study explored whether the specific focus of students' narratives (i.e., focus on trauma vs. focus on loss) as shared by TGCT-A group members would predict initial pretreatment levels, as well as pre- to posttreatment change trajectories, of PTSD symptoms and MG reactions. Thirty-three adolescents from three middle schools completed a 17-week course of group-based TGCT-A. PTSD and MG symptoms were assessed at pretreatment, twice during treatment, and at posttreatment. The focus (trauma vs. loss) of each student's narrative was coded using transcripts of members' narratives as shared within the groups. The reliable change index showed that 61% of students reported reliable pre-post improvement in either PTSD symptoms or MG reactions. Students whose narratives focused on loss both reported higher starting levels and showed steeper rates of decline in MG reactions than students whose narratives focused on trauma. In contrast, students whose narratives focused on trauma reported higher starting levels of PTSD than students who narrated loss experiences. However, narrative focus was not significantly linked to the rate at which PTSD symptoms declined over the course of treatment. This study provides preliminary evidence that TGCT-A treatment components are associated with reduced PTSD symptoms and MG reactions. Loss-focused narratives, in particular, appear to be associated with greater decreases in MG reactions. PMID:24927497

There is not much research done on US television's portrayal of sex and its relation to teenage attitudes and sex behavior. What has been done is on marital fidelity, gender roles, and rape myths. Sexuality taboos have created research problems. Future research should include longitudinal studies. These should use sex behavior as a dependent variable and focus on correlational and causal questions. Blacks, Hispanics, and Native Americans should be included in future research. Research should address the decision-making process within the television industry. A "consortium" of researchers from different disciplines should be used. Health professionals and the television industry should talk. Key people in professional organizations should have this dialog with the television industry. Press releases should be sent to key industry publications. The study group recommends a 6-12 month "sabbatical" wherein television and health professionals could work in each others' settings. There is a restriction on the advertising of contraceptive in the networks. Condoms can be promoted for disease protection, but not for birth control. Prescription products can't be advertised. Generic contraceptive advertisement should be created. Products could be advertised in magazines, too. Guidelines should be set up for television advertising. It is not possible to predict which hours adolescents will be watching television anymore. Critical viewing skills should be taught in "media literacy" curricula for "early and middle" adolescents.

OBJECTIVES. It is widely believed that risk factors identified in previous epidemiologic studies accurately predict adolescent drug use. Comparative studies are needed to determine how risk factors vary in prevalence, distribution, sensitivity, and pattern across the major US ethnic/racial groups. METHODS. Baseline questionnaire data from a 3-year epidemiologic study of early adolescent development and drug use were used to conduct bivariate and multivariate risk factor analyses. Respondents (n = 6760) were sixth- and seventh-grade Cuban, other Hispanic, Black, and White non-Hispanic boys in the 48 middle schools of the greater Miami (Dade County) area. RESULTS. Findings indicate 5% lifetime illicit drug use, 4% lifetime inhalant use, 37% lifetime alcohol use, and 21% lifetime tobacco use, with important intergroup differences. Monotonic relationships were found between 10 risk factors and alcohol and illicit drug use. Individual risk factors were distributed disproportionately, and sensitivity and patterning of risk factors varied widely by ethnic/racial subsample. CONCLUSIONS. While the cumulative prevalence of risk factors bears a monotonic relationship to drug use, ethnic/racial differences in risk factor profiles, especially for Blacks, suggest differential predictive value based on cultural differences.

The Advisory Committee on Immunization Practices (ACIP) recommends that adolescents aged 11-12 years routinely receive vaccines to prevent diseases, including human papillomavirus (HPV)-associated cancers, pertussis, and meningococcal disease (1). To assess vaccination coverage among adolescents in the United States, CDC analyzed data collected regarding 21,875 adolescents through the 2015 National Immunization Survey-Teen (NIS-Teen).* During 2014-2015, coverage among adolescents aged 13-17 years increased for each HPV vaccine dose among males, including ≥1 HPV vaccine dose (from 41.7% to 49.8%), and increased modestly for ≥1 HPV vaccine dose among females (from 60.0% to 62.8%) and ≥1 quadrivalent meningococcal conjugate vaccine (MenACWY) dose (from 79.3% to 81.3%). Coverage with ≥1 HPV vaccine dose was higher among adolescents living in households below the poverty level, compared with adolescents in households at or above the poverty level.(†) HPV vaccination coverage (≥1, ≥2, or ≥3 doses) increased in 28 states/local areas among males and in seven states among females. Despite limited progress, HPV vaccination coverage remained lower than MenACWY and tetanus, diphtheria, and acellular pertussis vaccine (Tdap) coverage, indicating continued missed opportunities for HPV-associated cancer prevention.

Despite the high coverage of prophylactic vaccine against Bordetella pertussis infection in many countries for more than three decades, pertussis remains a common vaccine-preventable disease. Infections have been detected more commonly in countries using acellular pertussis vaccine in their Expanded Program of Immunization. Thailand implemented a routine infant immunization program with whole-cell pertussis vaccine in 1977, and since 1992, the national vaccine policy has offered a five-dose whole-cell pertussis vaccine for children given at the ages of 2, 4, 6, 18, and 48 months. This study aimed to investigate the seroprevalence of antibodies to pertussis toxin among healthy people across all ages to determine the level of whole-cell vaccine-induced immunity in the population, and to identify which age group should be targeted for a booster dose. The lowest seronegative rate and highest geometric mean concentrations were found in the 0–10 years age group, corresponding to their recent pertussis vaccination. The proportion of people with undetectable IgG level was prominent, starting after 11 years of age onwards. Now that a reduced-dose pertussis vaccine with fewer adverse effects is available, a booster dose during adolescence should be considered in order to reduce the incidence of pertussis disease. Further studies exploring how long the reduced-dose pertussis vaccine can provide protective immunity against pertussis disease when administered to adults and adolescents should also be performed.

Nowadays, the age group affected from measles has widened and the disease has become more common among adolescents and young adults. The number of measles case reports have increased in our country, particularly from 2010-2011, and measles outbreaks occurred in various regions in 2012 and 2013. The aim of this study was to analyze the demographical and epidemiological characteristics, clinical and laboratory findings, and complications of adult patients with measles who were affected during the outbreak. A total of 28 patients (25 male, 3 female; age range: 19-39 years, median age: 24) who were hospitalized and followed-up in our clinic between January 2013 and June 2013, were evaluated. In the serum sample of the index case, measles-specific IgM antibodies were detected by ELISA, and measles virus RNA by real-time polymerase chain reaction (RT-PCR), then genotyping was performed to detect the epidemiological relationship. In all of the other cases, measles IgM and IgG antibodies were screened by ELISA. The most common symptoms on admission included high fever (n= 28, 100%), malaise (n= 25, 89%), sore throat (n= 25, 89%), headache (n= 20, 71%) and cough (n= 18, 64%). At physical examination, rash (n= 28, 100%), lymphadenopathy (n= 11, 39%) and conjunctivitis (n= 10, 36%) were in the foreground, and Koplik spots were detected in five (18%) cases. The most common laboratory findings were; increased level of C-reactive protein (n= 15, 54%), leukopenia (n= 12, 43%) and increased serum levels of aminotransferases (n= 12, 43%), and thrombocytopenia was detected in five (18%) patients. One or more complications (secondary bacterial pneumonia in 5, diarrhea in 4, hepatitis in 3 and otitis in 2 cases) developed in the eight (29%) patients. Measles RT-PCR and IgM tests yielded positive results for the index case, and the isolate was identified as D8 strain by genotyping. Measles lgM antibodies were also positive in all of the other cases. The hospitalization period was

Sexual problems such as forced and transactional sex are common among adolescents, especially in developing countries. The objective of the present study was to describe how young people respond to their social living conditions and why they marry early, have early pregnancies, experience forced sex and involve themselves in transactional sex. Young people, 15-24 years old, participated in focus group discussions that were tape recorded, translated into English, transcribed and analysed by qualitative content analysis. Six groups were mixed, with both women and men, while two groups had only men and one group only women as participants. The two study sites were located in a slum area in Kampala and in a village in Wakiso district, near a trading centre. The following topics were discussed: Forced sex, early marriage, contraception, teenage pregnancy and transactional sex. The participants described how young people are affected by harmful cultural practices, by power imbalance, especially due to gender-based inequity, and by lack of information and life skills. This study also showed that young people perceive themselves as a resource and are prepared to help other less advantaged youth to get knowledge about reproductive health issues. Enforcement of laws that can protect children and youth was suggested. Government and community should work against harmful traditional practices and introduce sexual education in primary school.

This longitudinal study investigated whether greater prepubertal adiposity was associated with subsequent timing of maturation and bone strength during adolescence in 135 girls and 123 boys participating in the Iowa Bone Development Study. Greater adiposity was defined using body mass index (BMI) data at age 8 years to classify participants as overweight (OW, ≥85th percentile for age and sex) or healthy weight (HW). Maturation was defined as the estimated age of peak height velocity (PHV) based on a series of cross-sectional estimates. Measurements were taken at ages 11, 13, 15, and 17 years for estimates of body composition by dual-energy X-ray absorptiometry (DXA), bone compression (bone strength index), and torsion strength (polar strength-strain index) at the radius and tibia by pQCT, and femoral neck bending strength (section modulus) by hip structural analysis. Bone strength in OW versus HW were evaluated by fitting sex-specific linear mixed models that included centered age (visit age - grand mean age of cohort) as the time variable and adjusted for change in fat mass, and limb length in model 1. Analyses were repeated using biological age (visit age - age PHV) as the time variable for model 1 with additional adjustment for lean mass in model 2. BMI was negatively associated with age of maturation (p < 0.05). OW versus HW girls had significantly greater bone strength (p < 0.001) in model 1, whereas OW versus HW boys had significantly greater bone strength (p < 0.001) at the tibia and femoral neck but not radius (p > 0.05). Analyses were repeated using biological age, which yielded reduced parameter estimates for girls but similar results for boys (model 1.) Differences were no longer present after adjustment for lean mass (model 2) in girls (p > 0.05) whereas differences at the tibia were sustained in boys (p < 0.05). These findings demonstrate sex- and site-specific differences in the associations between adiposity, maturation, and

The aim of this study were to assess bullying and its associated factors in school-going adolescents in Thailand. Using data from the Thailand Global School-Based Student Health Survey (GSHS) 2008, the prevalence of being bullied and its associated factors among adolescents (N=2758) was assessed. The study found an overall prevalence of being bullied on one or more days during the past 30 days of 27.8%, 32.9% among males and 23.2% among females. The predominant forms of being bullied were among boys being hit, kicked, pushed, shoved around, or locked indoors and among girls making fun of with sexual jokes, comments, and gestures. Among boys risk factors for having been bullied were younger age (adjusted odds ratio to (AOR): 0.34; 95% confidence interval (CI): 0.18-0.65), having been in a physical fight (AOR: 3.64; 95% CI: 2.84-4.66), being physically inactive (AOR: 1.49; 95% CI: 1.04-2.15), truancy (AOR: 1.66; 95% CI: 1.13-2.45), and psychosocial distress (AOR: 2.07; 95% CI: 1.14-3.74), and among girls risk factors for having been bullied were having been in a physical fight (AOR: 2.91; 95% CI: 2.00-4.24), lack of parental bonding (AOR: 0.71; 95% CI: 0.51-0.99), and psychosocial distress (AOR: 2.37; 95% CI: 1.39-4.03). Results may inform school health programmes on the prevalence and correlates of bullying among adolescents in Thailand. PMID:23476124

Computer-assisted data collection offers advantages over traditional paper and pencil measures; however, little guidance is available regarding the logistics of conducting computer-assisted data collection with adolescents in group settings. To address this gap, we draw on our experiences conducting a multi-site longitudinal study of adolescent development. Structured questionnaires programmed on laptop computers using Audio Computer Assisted Self-Interviewing (ACASI) were administered to groups of adolescents in community-based and afterschool programs. Although implementing ACASI required additional work before entering the field, we benefited from reduced data processing time, high data quality, and high levels of youth motivation. Preliminary findings from an ethnically diverse sample of 265 youth indicate favorable perceptions of using ACASI. Using our experiences as a case study, we provide recommendations on selecting an appropriate data collection device (including hardware and software), preparing and testing the ACASI, conducting data collection in the field, and managing data.

Background: Childhood obesity has become one of the most serious public health challenges in the 21st century in most developing countries. The percentile curve tool is useful for monitoring and screening obesity at population level, however, in China, no official recommendations on childhood body mass index (BMI) and waist circumference (WC) reference percentiles have been made in practice. Aims: to construct the percentile reference values for BMI and WC, and then to calculate the prevalence of overall and abdominal obesity for Chinese children and adolescents. Methods: A total of 5062 anthropometric records for children and adolescents aged from 7 to 18 years (2679 boys and 2383 girls) were included for analysis. The participants were recruited as part of the national representative “China Health and Nutrition Survey” (CHNS). Age, gender, weight, height, and WC were assessed. Smoothed BMI and WC percentile curves and values for the 3rd, 5th, 10th, 15th, 25th, 50th, 75th, 85th, 90th, 95th and 97th percentiles were constructed by using the Lambda-Mu-Sigma (LMS) method. The prevalence estimates of the overall and abdominal obesity were calculated by using the cut-offs from our CHNS study and the previous “Chinese National Survey on Students’ Constitution and Health” (CNSSCH) study, respectively. The difference between prevalence estimates was tested by a McNemar test, and the agreement between these prevalence estimates was calculated by using the Cohen’s kappa coefficient. Results: The prevalence values of overall obesity based on the cut-offs from CHNS and CNSSCH studies were at an almost perfect agreement level in boys (κ = 0.93). However, among girls, the overall obesity prevalence differed between the studies (p < 0.001) and the agreement was weaker (κ = 0.76). The abdominal obesity prevalence estimates were significant different according to the two systems both in boys and girls, although the agreement reached to 0.88, which represented an

We describe 2 frameworks in which personality dimensions relevant to health, such as Conscientiousness, can be used to inform interventions designed to promote health aging. First, contemporary data and theory do not suggest that personality is "immutable," but instead focus on questions of who changes, in what way, why, when, and how.…

Now a days, benign prostatic hyperplasia and carcinoma of the prostate are the most common disorders in men. A cross sectional descriptive study was conducted in Department of Anatomy, Mymensingh Medical College, Mymensingh to find out the difference in weight of the prostate gland of Bangladeshi people in relation to age. The present study was performed on 67 postmortem human prostate gland collected from the morgue in the Department of Forensic Medicine, Mymensingh Medical College by non random purposive sampling technique. The specimens were collected from Bangladeshi cadaver of age ranging from 10 to 80 years. All the specimens were grouped into three categories - Group A (upto 18 years), Group B (19 to 45 years) and Group C (above 45 years) according to age. Dissection was performed according to standard autopsy techniques. The weight of the prostate gland were measured and recorded. The mean weight of the prostate gland was 10.13gm in Group A, 17.27gm in Group B and 22.50gm in Group C. Variance analysis shows that mean differences of weight of the prostate were highly significant among all age groups. The weight of prostate gland was found to increase with increased age. For statistical analysis, differences between age groups were analyzed by using students unpaired 't' test. The present study will help to increase the information pool on the weight of prostate gland of Bangladeshi people. PMID:27612887

The aim of the current study was to describe participants' experiences and examine the effects of group therapy on self-esteem and state anger among the adolescent children of immigrants in the US. A quasi-experimental design and qualitative and quantitative methods were used. Group therapy was conducted for 8weeks. Thirty-three adolescents took part in the study. Quantitative results revealed that group therapy improved self-esteem (t=2.222. p<.05) but not state anger. However, qualitative results suggested that group therapy helped improve interpersonal relationships and communication skills, the forgiveness of others, and the management of anger. Furthermore, group therapy utilizing positive psychology strategies improved self-esteem, interpersonal relationships, and communication skills. PMID:25858203

P300 event related potential was recorded in 115 healthy controls with a mean age of35.9±14.81 years and a male : female ratio of 72 : 43. There was significant difference in the P300 latency in < 40 years as compared to ≥ 40 years group (p< 0.001). There was no significant difference between males and females. There was a strong positive correlation between age and P300 latency (p< 0.001). The regression equation for P300 latency was Y=287.9+1.492x with an SEE of 20.2 (where Y is the P300 latency in ms, x is the age in years, SEE is the standard error of estimate). There was a negative correlation between age and P300 amplitude which was significant in ≥ 40 years age group while in > 40 years age group it was not significant. PMID:21407977

Although studies of long-term outcomes of children born preterm consistently show low intelligence quotient (IQ) and visual-motor impairment, studies of their performance in language and reading have found inconsistent results. In this study, we examined which specific language and reading skills were associated with prematurity independent of the effects of gender, socioeconomic status (SES), and IQ. Participants from two study sites (N=100) included 9-16-year old children born before 36 weeks gestation and weighing less than 2500 grams (preterm group, n=65) compared to children born at 37 weeks gestation or more (full-term group, n=35). Children born preterm had significantly lower scores than full-term controls on Performance IQ, Verbal IQ, receptive and expressive language skills, syntactic comprehension, linguistic processing speed, verbal memory, decoding, and reading comprehension but not on receptive vocabulary. Using MANCOVA, we found that SES, IQ, and prematurity all contributed to the variance in scores on a set of six non-overlapping measures of language and reading. Simple regression analyses found that after controlling for SES and Performance IQ, the degree of prematurity as measured by gestational age group was a significant predictor of linguistic processing speed, β=-.27, p<.05, R(2)=.07, verbal memory, β=.31, p<.05, R(2)=.09, and reading comprehension, β=.28, p<.05, R(2)=.08, but not of receptive vocabulary, syntactic comprehension, or decoding. The language and reading domains where prematurity had a direct effect can be classified as fluid as opposed to crystallized functions and should be monitored in school-aged children and adolescents born preterm.

Large-scale, heteroplasmic and generally pathogenic mtDNA defects (as induced by defective mitochondrial DNA polymerase, clonal mutations or DNA deletions) are known to negatively impact on life span and can result in apoptosis and tissue loss in, e.g., skeletal muscle or reduce learning abilities. The functional impact of homoplasmic specific mtDNA point mutations, e.g., in genes coding for the electron transport chain, however, remains a matter of debate. The present study contributes to this discussion and provides evidence that a single point mutation in complex I of the respiratory chain is associated with impairment of spatial navigation in adolescent (6-month-old) mice, i.e., reduced performance in the Morris Water Maze, which goes along with increased production of reactive oxygen species (ROS) in juvenile mice (3 months) but not at the age of phenotype expression. A point mutation in complex III goes along with only a mild and non-significant negative effect on cognitive performance and no significant changes in ROS production. These findings suggest to also consider the ontogenetic development of phenotypes when studying mtDNA mutations and highlights a possible impact of complex I dysfunction on the emergence of neurological deficits.

Background The wellness construct has application in a number of fields including education, healthcare and counseling, particularly with regard to female adolescents. The effective measurement of wellness in adolescents can assist researchers and practitioners in determining lifestyle behaviors in which they are lacking. Behavior change interventions can then be designed which directly aid in the promotion of these areas. Methods The 5-Factor Wellness Inventory (designed to measure the Indivisible Self model of wellness) is a popular instrument for measuring the broad aspects of wellness amongst adolescents. The instrument comprises 97 items contributing to 17 subscales, five dimension scores, four context scores, total wellness score, and a life satisfaction index. This investigation evaluated the test-retest (intra-rater) reliability of the 5F-Wel instrument in repeated assessments (seven days apart) among adolescent females aged 12–14 years. Percentages of exact agreement for individual items, and the number of respondents who scored within ±5, ±7.5 and ±10 points for total wellness and the five summary dimension scores were calculated. Results Overall, 46 (95.8%) participants responded with complete data and were included in the analysis. Item agreement ranged from 47.8% to 100% across the 97 items (median 69.9%, interquartile range 60.9%-73.9%). The percentage of respondents who scored within ±5, ±7.5 and ±10 points for total wellness at the re-assessment was 87.0%, 97.8% and 97.8% respectively. The percentage of respondents who scored within ±5, ±7.5 and ±10 for the domain scores at the reassessment ranged between 54.3-76.1%, 78.3-95.7% and 89.1-95.7% respectively across the five dimensions. Conclusions These findings suggest there was considerable variation in agreement between the two assessments on some individual items. However, the total wellness score and the five dimension summary scores remained comparatively stable between assessments

Age groups of Antarctic krill ( Euphausia superba Dana) in the Prydz Bay region were studied by distribution mixture analysis based on length/frequency data collected by R/V Jidi during the 1989/1990 and 1990/1991 austral summer. Five age groups were determined, i.e. 1+, 2+, 3+, 4+, and 5+, or six age groups in all, if the 0+ larvae were included. The mean body length of 1+ to 5+ age groups was 25.70 mm, 40.47 mm, 45.52 mm, 50.52 mm and 54.52 mm respectively. Supposing the difference in body length between successive age groups is a reflection of the early growth, the maximum growth rate occurred during the period from 1+ juveniles to 2+ subadults (14.77 mm/a). From 2+ subadults to 3+ adults the growth rate dropped steeply (5.05 mm/a) because at this stage, increase of body length was substituted, to a great extent, by the growth of sexual products. From 3+ onwards the growth rate was maintained at a relatively low level and decreased slowly with age. The relative abundance of age groups 1+ and 2+, in our sample must be much lower than that in the real population owing to both the large mesh size we used and the distribution difference between juveniles and adults. If we left aside 1+ and 2+ age groups and just looked at the relative abundance of adults, we found that age group 3+ dominated the adult population and that the relative abundance decreased sharply with increasing age. If this situation is normal, one can expect an extremely high mortality rate in adults, 82.6% from 3+ to 4+ and 94.0% from 4+ to 5+. This is reasonably expectable for the Prydz Bay region.

Do children derive different benefits from group collaboration at different ages? In the present study, 183 children from two age groups (8.8 and 13.4 years) took part in a class quiz as members of a group, or individually. In some groups, cohesiveness was made salient by awarding prizes to the top performing groups. In other groups, prizes were awarded to the best performing individuals. Findings, both in terms of social outcomes and performance in the quiz, indicated that the 8-year olds viewed the benefits of group membership in terms of the opportunities to receive information from other members. The 13-year olds, in contrast, viewed group collaboration as a constructive process where success was connected with group cohesiveness. PMID:25250886

Objective To investigate correlates of eating disorder psychopathology in adolescent males and females with type 1 diabetes. Method A total of 105 adolescents with type 1 diabetes (42% males), aged 12–20 years, were recruited from the Norwegian Childhood Diabetes Registry in this population-based study. All participants were interviewed with the Child Eating Disorder Examination. Additionally, the Brief Illness Perception Questionnaire, the Adolescent Coping Orientation for Problem Experiences and the Beliefs about Medicines Questionnaire were administered to assess health-related functioning. Clinical data were obtained from the Norwegian Childhood Diabetes Registry. Results Significant gender differences were demonstrated in the pattern of correlates of eating disorder pathology. Among females, eating disorder psychopathology was significantly associated with body mass index adjusted for age and gender, age, insulin restriction, coping, illness perceptions, and perceptions of insulin concern. In a regression model, age, illness perceptions, and insulin restriction remained significantly associated with eating disorder psychopathology, explaining 48% of the variance. None of the variables were associated with eating disorder psychopathology among males. Discussion Greater clinical awareness of illness perceptions, attitudes toward insulin, and insulin restriction may potentially decrease the risk of developing eating disorders among female adolescents with type 1 diabetes, and the subsequent increased morbidity and mortality associated with comorbid type 1 diabetes and eating disorders.

Anxiety in situations where one's overall appearance (including body shape) may be negatively evaluated is hypothesized to play a central role in Eating Disorders (EDs) and in their co-occurrence with Social Anxiety Disorder (SAD). Three studies were conducted among community (N = 1995) and clinical (N = 703) ED samples of 11- to 18-year-old Italian girls and boys to (a) evaluate the psychometric qualities and measurement equivalence/invariance (ME/I) of the Social Appearance Anxiety (SAA) Scale (SAAS) and (b) determine to what extent SAA or other situational domains of social anxiety related to EDs distinguish adolescents with an ED only from those with SAD. Results upheld the one-factor structure and ME/I of the SAAS across samples, gender, age categories, and diagnostic status (i.e., ED participants with and without comorbid SAD). The SAAS demonstrated high internal consistency and 3-week test-retest reliability. The strength of the inter-relationships between SAAS and measures of body image, teasing about appearance, ED symptoms, depression, social anxiety, avoidance, and distress, as well as the ability of SAAS to discriminate community adolescents with high and low levels of ED symptoms and community participants from ED participants provided construct validity evidence. Only SAA strongly differentiated adolescents with any ED from those with comorbid SAD (23.2 %). Latent mean comparisons across all study groups were performed and discussed. PMID:25976291

Levels of civic engagement are assumed to vary according to numerous social and psychological characteristics, but not much is known about online civic engagement. This study aimed to investigate differences and similarities in young people's offline and online civic engagement and to clarify, based on Ajzen's theory of planned behavior (TPB), associations between motivation for civic engagement, peer and parental norms, collective efficacy, and civic engagement. The sample consisted of 755 youth (native German, ethnic German Diaspora, and Turkish migrants) from two age groups (16-18 and 19-26; mean age 20.5 years; 52 % female). Results showed that ethnic group membership and age moderated the frequency of engagement behavior, with Turkish migrants taking part more than native Germans, who were followed by ethnic German Diaspora migrants. Analyses based on TPB showed good fit for a model relating intention for offline and online civic engagement to motivation for civic engagement, peer and parental norms, and collective efficacy. Ethnic group moderated the findings for offline civic engagement and questioned the universality of some model parameters (e.g., peer and parental norms). This study showed the utility of the TPB framework for studying civic engagement but also reveals that the predictive utility of peer and parental norms seems to vary depending on the group and the behavior under study. This study highlights the importance of including minority samples in the study of civic engagement in order to identify between-group similarities and differences. PMID:22903193

Purpose To examine the prospective associations of physical activity at 11, 15 and 18 years of age with cognitive performance in young adulthood in a large birth cohort study from Brazil. Methods Participants were part of a large birth cohort study in Pelotas, Brazil (n = 3235 participants). Physical activity was self-reported at 11, 15 and 18 years and also was objectively measured at 18 years. Cognitive performance was assessed using an adapted Brazilian version of the short form of the Wechsler Adult Intelligence Scale (WAIS-III) at 18 years. Results At 11 years, participants in the middle tertile of self-reported physical activity presented a significantly higher cognitive performance score as compared to the lowest tertile. Physical activity at 15 years of age was unrelated to cognitive performance at 18 years. Self-reported physical activity was cross-sectionally positively associated with cognitive performance at 18 years (p<0.001). Data from objectively measured physical activity at 18 years showed that those in the highest moderate to vigorous physical activity tertile presented lower cognitive performance scores at 18 years as compared to those in the lowest tertile (−2.59; 95%CI: −3.41; −1.48). Analyses on changes in tertiles of physical activity showed that maintaining an intermediate physical activity level from 11 to 18 years and from 15 to 18 years was associated with higher cognitive performance score of 2.31 (95%CI: 0.71; 3.91) and 1.84 score (95%CI: 0.25; 3.42), respectively. Conclusion Physical activity throughout adolescence is associated with cognitive performance before adulthood. Adolescents who are active at moderate levels, specifically those who maintain these levels of physical activity, tend to show higher cognitive performance. However, high levels of physical activity might impair cognitive performance. PMID:25973558

This study investigated differences in social-cognitive predictors and self-regulatory planning, as proposed by the health action process approach (HAPA), across three different subjective physical age groups for physical activity. With a cross-sectional design, 521 participants across the chronological age span from 25 to 86 years (M = 48.79; SD = 12.66) were separated into three groups: those who feel physically younger than they are in terms of chronological age, the same perceived and chronological age, and feeling physically older compared to their chronological age. Participants were assessed regarding their perceived vulnerability, outcome expectancies, general intentions, planning, self-efficacy, and stages of physical activity (non-intenders, intenders, and actors). Data were analysed via mean comparison and multigroup structural equation modelling. Mean differences for all but one construct were eminent in all groups, generally showing that those feeling physically younger also report better social-cognitive predictors of physical activity (e.g. lower perceived vulnerability) in comparison to those who feel the same age or older. The model showed that basic working mechanisms of the HAPA can be applied to all groups. With that, the results provide for the first time evidence that principle working mechanism of the HAPA can be applied to all subjective physical age groups. These may be used to tailor health promoting interventions according to participants' needs as a more suitable proxy than chronological age. PMID:26967593

Age has been included in various prognostic scoring systems for differentiated thyroid cancer (DTC). The aim of this study is to re-examine the relationship between age and prognosis by using Surveillance, Epidemiology, and End Results (SEER) population-based database. We identified 51,061 DTC patients between 2004 and 2012. Patients were separated into 10-year age groups. Cancer cause-specific survival (CSS) and overall survival (OS) data were obtained. Kaplan-Meier and multivariable Cox models were built to analyze the outcomes and risk factors. Increasing age gradient with a 10-year interval was associated with the trend of higher proportions for male gender, grade III/IV and summary stage of distant metastases. Both CSS and OS continued to worsen with increasing age, being poorest in in the oldest age group (≥71); multivariate analysis confirmed that CSS continued to fall with each age decade, significantly starting at 60 years (HR = 7.5, 95% 1.0-54.1, p = 0.047) compared to the young group (≤20). Similarly, multivariate analysis suggested that OS continued worsening with increasing age, but starting at 40 years (HR = 3.7, 95% 1.4-10.1, p = 0.009) compared to the young group. The current study suggests that an age exceeding 60 years itself represents an unfavorable prognostic factor and high risk for cancer-specific death in DTC. PMID:27272218

Both CSS and OS continued to worsen with increasing age, being poorest in in the oldest age group (≥71); multivariate analysis confirmed that CSS continued to fall with each age decade, significantly starting at 60 years (HR = 7.5, 95% 1.0–54.1, p = 0.047) compared to the young group (≤20). Similarly, multivariate analysis suggested that OS continued worsening with increasing age, but starting at 40 years (HR = 3.7, 95% 1.4–10.1, p = 0.009) compared to the young group. The current study suggests that an age exceeding 60 years itself represents an unfavorable prognostic factor and high risk for cancer-specific death in DTC. PMID:27272218
