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

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

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

Obesity rates are rising in the United States, especially among low-income and racial/ethnic minority individuals. Exploring motivators and barriers relative to engaging in physical activity is imperative. The purpose of this study was to identify motivators and barriers relative to engagement in physical activity as reported by culturally diverse low-income adolescents and adults. A total of 91 adolescent (11 to 15 years of age) and adult (18 years of age or older) participants who self-identified as African American, Hispanic, or non-Hispanic White engaged in age group-, race/ethnicity-, and gender-concordant focus groups. Qualitative data analysis indicated that the motivators and barriers most commonly identified among the adolescent and adult focus groups were: social influence; time and priorities; physical environment; fun and enjoyment; inherently physical activities; weight concerns; fatigue, physical discomfort and current fitness level; and immediate positive feelings. Findings were generally similar across age group, gender and race/ethnicity. Age group-specific, gender-specific and race/ethnicity-specific motivators and barriers were related to how commonly the motivators and barriers were identified among each group. Implications for increasing physical activity among low-income culturally diverse adolescents and adults are discussed.

Language has been shown to play a critical role in social cognitive reasoning in preschool and school-aged children, but little research has been conducted with adolescents. During adolescence, the ability to understand figurative language becomes increasingly important for social relationships and may affect social adjustment. This study investigated the contribution of structural and figurative language to social cognitive skills in adolescents who present for mental health services and those who do not. One hundred and thirty-eight adolescents referred to mental health centers (clinic group) and 186 nonreferred adolescents (nonclinic group) aged 12-17 were administered measures of structural and figurative language, working memory, and social cognitive problem solving. We found that adolescents in the clinic group demonstrated less mature social problem solving overall, but particularly with respect to anticipating and overcoming potential obstacles and conflict resolution compared with the nonclinic group. In addition, results demonstrated that age, working memory, and structural and figurative language predicted social cognitive maturity in the clinic group, but only structural language was a predictor in the nonclinic group. Social problem solving may be particularly difficult for adolescents referred for mental health services and places higher demands on their cognitive and language skills compared with adolescents who have never been referred for mental health services. © 2013 The Authors.

Developmental trajectories of parents' knowledge of their adolescents' whereabouts and activities were tested as moderators of transactional associations between friends' antisociality and adolescent delinquent behavior. 504 adolescents (50% female) provided annual reports (from ages 12 to 16) of their parents' knowledge and (from ages 13 to 16) their own delinquent behavior and their friends' antisociality. Parents also reported the adolescents' delinquent behavior. Growth mixture modeling was used to identify two sub-groups based on their monitoring knowledge growth trajectories. Adolescents in the sub-group characterized by decreasing levels of parents' knowledge reported more delinquent behavior and more friend antisociality in early adolescence, and reported greater increases in delinquent behavior and friend antisociality from early to middle adolescence compared to adolescents in the sub-group characterized by increasing levels of parents' knowledge. Transactional associations consistent with social influence and social selection processes also were suppressed in the increasing knowledge sub-group as compared to the decreasing knowledge sub-group.

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

Objectives Explore associations between maternal and neonatal outcomes and maternal age, with particular reference to adolescent women. Design Population-based cohort study. Setting Maternity department of a large hospital in Northern England. Participants Primiparous women delivering a singleton at Bradford Royal Infirmary between March 2007 and December 2010 aged ≤19 years (n=640) or 20–34 years (n=3951). Subgroup analysis was performed using women aged ≤16 years (n=68). Women aged 20–34 years were used as the reference group. Primary outcome measures Maternal and neonatal outcomes. Results The odds of extremely low birth weight (<1000 g) were significantly higher in the adolescent group (≤19 years) compared with the reference group (adjusted OR (aOR) 4.13, 95% CI 1.41 to 12.11). The odds of very (<32 weeks) and extremely (<28 weeks) preterm delivery were also higher in the adolescent group (aOR 2.12, 95% CI 1.06 to 4.25 and aOR 5.06, 95% CI 1.23 to 20.78, respectively). Women in the adolescent group had lower odds of gestational diabetes (aOR 0.35, 95% CI 0.20 to 0.62), caesarean delivery (aOR 0.53, 95% CI 0.42 to 0.67 and instrumental delivery (aOR 0.53, 95% CI 0.41 to 0.67). Conclusions This study identifies important differences in maternal and neonatal outcomes between women by age group. These findings could help in identifying at-risk groups for additional support and tailored interventions to minimise the risk of adverse outcomes for these vulnerable groups. Further work is needed to identify the causal mechanisms linking age with outcomes in adolescent women where significant gaps in the literature exist. PMID:29549196

Routinely vaccinating adolescents against meningococcus: targeting transmission & disease

ABSTRACT Adolescents have the highest rates of meningococcal carriage and transmission. Interrupting the adolescent habitat in order to reduce carriage and transmission within adolescents and to other age groups could help to control meningococcal disease at a population level. Compared to immunization strategies restricted to young children, a strategy focused on adolescents may have more profound and long-lasting indirect impacts, and may be more cost effective. Despite challenges in reaching this age-group, experience with other vaccines show that high vaccine coverage of adolescents is attainable. PMID:26651380

Quantify the homeostatic and circadian effects on sleepiness and performance of adolescents. Examine age-related changes in homeostatic and circadian regulation of sleepiness and performance by comparing younger and older adolescent groups. Three-week laboratory study including 12 cycles of a 28-h forced desynchrony protocol. Controlled laboratory environment with individual sleep and performance testing rooms and shared common areas. Twenty-seven healthy adolescents including 16 females. Ages ranged from 9.6-15.2 years and participants were split into younger (n = 14 ages 9-12) and older (n = 13 ages 13-15) groups based on median age split of 13.0 years. N/A. Testing occurred every 2 h during scheduled wake periods. Measures included sleep latency during repeated nap opportunities and scores from a computerized neurobehavioral assessment battery including a 10-min psychomotor vigilance task, a digit symbol substitution task, and the Karolinska Sleepiness Scale. Significant main effects of circadian and homeostatic factors were observed, as well as several circadian and homeostatic interaction effects. Age group did not have a significant main effect on sleep and performance data. A significant interaction of circadian phase and age group was found for sleep latency, with younger adolescents showing greater circadian modulation than older teens during the circadian night. Adolescents demonstrated a similar pattern of response to forced desynchrony as reported for adults. Sleepiness and performance were affected by homeostatic and circadian factors, and age group did not interact with homoeostatic and circadian factors for subjective sleepiness and most performance metrics. Younger adolescents had a shorter latency to sleep onset than older during the circadian bin spanning 4 to 8 h after the onset of melatonin secretion. © 2015 Associated Professional Sleep Societies, LLC.

Previous studies have convincingly shown associations between popularity and adolescent drinking. This study examined whether the popularity composition of the peer group and the relative difference in popularity between adolescents and their peers are also associated with adolescent drinking. Participants were 800 adolescents (M age  = 14.73; SD age  = 1.00; 51.6 % girls) from 31 classrooms who completed peer ratings of popularity and self-reports of alcohol consumption. Results showed that drinking was higher among popular than unpopular adolescents, higher among popular adolescents surrounded by less popular classmates, and lower in classrooms with more variability in popularity. Thus, beyond individual popularity, peer group popularity composition also should be taken into account when investigating antisocial and health risk behaviors in adolescence such as drinking.

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.

Prodromal syndromes often begin in adolescence - a period of neurodevelopmental changes and heightened stress sensitivity. Research has shown elevated stress and cortisol in individuals at clinical high risk (CHR) for psychosis. This cross-sectional study examined relations of age and pubertal status with cortisol and self-reported stress in healthy controls (HCs) and CHR adolescents. It was hypothesized that the relations of age and pubertal stage with cortisol and stress would be more pronounced in CHR youth. Participants were 93 HCs and 348 CHR adolescents from the North American Prodrome Longitudinal Study (NAPLS). At baseline, measures of stress (Daily Stress Inventory - DSI), Tanner stage (TS), and salivary cortisol were obtained. ANCOVA revealed increased DSI scores with age for both groups, and higher DSI scores in CHR adolescents than HCs, with a more pronounced difference for females. Contrary to prediction, with age controlled, HCs showed greater TS-related DSI increases. Analysis of cortisol showed no significant interactions, but a main effect of age and a trend toward higher cortisol in the CHR group. Correlations of cortisol with TS were higher in HC than CHR group. Stress measures increased with age in HC and CHR adolescents, and DSI scores also increased with TS in HCs. The results do not support a more pronounced age or TS increase in stress measures in CHR adolescents, but instead suggest that stress indices tend to be elevated earlier in adolescence in the CHR group. Potential determinants of findings and future directions are discussed. Copyright © 2016 Elsevier B.V. All rights reserved.

Overweight and obesity are serious health concerns for children. However, only a few studies have investigated the influence of gender on prevalence of overweight and obesity in children and adolescents in Nigeria. The objective of this study was to investigate gender influence on prevalence of overweight and obesity among Nigerian school children and adolescents. Information on age and gender of the participants was collected from the school register. Data on height, weight and BMI was collected using standard techniques. A total of 9,014 children and adolescents (male = 4392; female = 4622), aged 2-18 years, from 28 randomly selected schools were analyzed. Overweight and obesity were determined using the International Obesity Task Force cut-off points by age and gender. Males had higher BMI than females at age group 2-6 years, whereas females had higher BMI than males at age groups 11-14 years and 15-18 years. Females had significantly higher prevalence of overweight (P < 0.05) than males at age group 11-14 and 15-18 years. However, there was no gender difference in the prevalence of obesity from childhood through adolescence. In conclusion, BMI is larger in males in early childhood but larger in females in during adolescence. More female adolescents are at risk of obesity than males.

The aim of this study was to compare attachment styles and psychopathology in adolescent children of parents with bipolar disorder (BD) with a healthy control group. We studied 25 adolescents who had at least 1 parent with BD (BD group) and 28 adolescents who had no parents with BD (control group). The adolescent participants were between the ages of 12 and 17 years. We used the Adolescent Relationship Scales Questionnaire (A-RSQ) for the adolescents in the BD vs. control groups, and we used the Schedule for Affective Disorders and Schizophrenia for School-age Children - present and lifetime version (K-SADS-PL). We used the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I), Clinician Version for each parent of adolescents in the BD and control groups to rule out psychopathologies. Attachment styles of participants were assessed according to A-RSQ, dismissing attachment style scores of adolescents in BD group were found significantly higher compared to the healthy control group (p<0.05). As a result of the assessments, 12 adolescents (48%) out of 25 in the BD group and 5 adolescents (18%) out of 28 in the control group were given DSM-IV Axis I diagnosis, which is a statistically significant result (p<0.05). However, when psychiatric diagnoses were assessed separately, the difference was not statistically significant. We found that the adolescent children of parents with BD have increased risk of developing mental illnesses, and that these adolescents adopt dismissing attachment styles.

Children and adolescents who train extensively in high-impact, weight-bearing activities have enhanced bone mineral density. The purpose of this study was to evaluate bone strength, as reflected by quantitative ultrasound (QUS, Sunlight Omniscence), of child (10-12 yrs old) and adolescent (14-16 yrs old) male soccer and hockey players in comparison with age-matched controls. The groups included 30 child (CH) and 31 adolescent (AH) hockey players, 26 child (CS) and 30 adolescent (AS) soccer players, as well as 34 child (CC) and 31 adolescent (AC) healthy, non-athletic, age-matched controls. All athletes trained at an elite level year-round, with no difference in training volume between groups. Ultrasound speed of sound (SOS) was measured at the distal-radius and mid-tibia. In both age groups, hockey players were the heaviest and had the highest fat-free mass. No differences were found among groups in total energy intake, calcium or vitamin D intake. Radial and tibial SOS increased with age. Hockey players had higher radial SOS in both age groups (children: CH:3763+/-74, CS:3736+/-77, CC:3721+/-88 m/s; adolescents: AH:3809+/-105, AS:3767+/-85, AC:3760+/-94 m/s). Tibial SOS was higher in soccer players compared with controls. In spite of the higher body mass and fat-free mass in hockey players, their tibial SOS was similar to the non-athletes in both age groups. These findings support previous suggestions of sport-specific effects on bone strength. However, they need to be corroborated with longitudinal or prospective intervention studies.

2014-02-01

A well-established body of literature demonstrates concurrent associations between personality traits and major depressive disorder (MDD), but there have been relatively few investigations of their dynamic interplay over time. Prospective inter-relationships between late-adolescent personality and MDD in early adulthood were examined in a community sample of male and female twins from the Minnesota Twin Family Study (MTFS; n = 1252). Participants were classified into naturally occurring MDD groups based on the timing (adolescent versus adult onset) and course (chronic/recurrent versus remitting) of MDD. MDD diagnoses were assessed at ages 17, 20, 24 and 29 years, and personality traits [negative emotionality (NEM), positive emotionality (PEM) and constraint (CON)] were assessed at ages 17, 24 and 29 years. Multilevel modeling (MLM) analyses indicated that higher age-17 NEM was associated with the subsequent development of MDD, and any MDD, regardless of onset or course, was associated with higher NEM up to age 29. Moreover, the chronic/recurrent MDD groups failed to show the normative decrease in NEM from late adolescence to early adulthood. Lower age-17 PEM was also associated with the subsequent development of MDD but only among the chronic/recurrent MDD groups. Finally, the adolescent-onset MDD groups reported lower age-17 CON relative to the never-depressed and adult-onset MDD groups. Taken together, the results speak to the role of personality traits for conferring risk for the onset of MDD in late adolescence and early adulthood, in addition to the pernicious implications of chronic/recurrent MDD, particularly when it onsets during adolescence, for adaptive personality development.

Duration of Untreated Psychosis (DUP) is an important measure associated with outcome of psychosis. This first study in the UK compared DUP between adolescent and adult-onset individuals and explored whether the adolescent-onset group showed variations in DUP that could be accounted for by sociodemographic and selected risk factors. This naturalistic cohort study included 940 new first-episode psychosis cases aged 14-35years (136 adolescent-onset versus 804 adult-onset psychotic individuals) referred to nine Early Intervention Services for Psychosis in London (2003-2009). Sociodemographic characteristics, age of onset, family history of mental illness, duration of untreated psychosis, suicidality and substance use information were collected at entry to the services. Adolescents presented with significantly greater median DUP (179days) than adults (81days, p=0.005). Large differences in DUP were found amongst adolescent ethnic groups (median DUP: White: 454days; Black: 103days; Asian and mixed: 28.5days). In addition, younger age of onset and higher lifetime cannabis use were associated with longer treatment delay amongst adolescents. This study of DUP in adolescent-onset psychosis found it to be approximately twice the length of DUP amongst adults. For the adolescent White sub-group, DUP was far greater than the UK Department of Health target (<3months). Both the high rates of lifetime cannabis use and the lower age of onset might explain the long DUP in this ethnic group. Physicians need to be particularly vigilant about identifying and managing early psychosis in adolescents. © 2013.

This study explored perceptions about sexual behaviors and attitudes of adolescents living in Soweto, Johannesburg, South Africa, from the perspective of parents, counselors and adolescents. A qualitative methodology was applied. Nine focus group discussions (FGDs) were held; three with parents of adolescents, two with counselors who work with adolescents, two with female adolescents aged 16-18 years and two with male adolescents aged 16-18 years. In total, 80 participants were recruited from in and around Soweto. FGDs were guided by a semi-structured interview guide, audio-recorded, transcribed verbatim and translated into English. Data were analyzed using Maxqda, a qualitative software analysis program. There were eight key themes related to adolescent sexuality and perceived attitudes towards relationships. Five themes were common to all participant groupings (parents, counselors and adolescents): (1) dating during adolescence, (2) adolescent females dating older males, (3) condom use amongst adolescents, (4) pregnancy and (5) homosexuality. (6) Sex as a regular and important activity among adolescents and (7) group sex practices among adolescents emerged as themes from adolescent and counselor FGDs. Lastly, (8) the role of the media as an influence on adolescent sexuality was common to adolescent and parent groups. Risky sexual behaviors continue among adolescents, with group sex parties a concerning emergent phenomenon that necessitates further study. HIV, other STIs and pregnancy prevention interventions should address multiple levels of influence to address context-specific influences. PMID:22844344

Background Obesity rates are rising in the United States, especially among low-income and racial/ethnic minority individuals. Exploring motivators and barriers relative to engaging in physical activity is imperative. Purpose The purpose of this study was to identify motivators and barriers relative to engagement in physical activity as reported by culturally diverse low-income adolescents and adults. Methods A total of 91 adolescent (11 to 15 years of age) and adult (18 years of age or older) participants who self-identified as African American, Hispanic, or non-Hispanic White engaged in age group-, race/ethnicity-, and gender-concordant focus groups. Results Qualitative data analysis indicated that the motivators and barriers most commonly identified among the adolescent and adult focus groups were: social influence; time and priorities; physical environment; fun and enjoyment; inherently physical activities; weight concerns; fatigue, physical discomfort and current fitness level; and immediate positive feelings. Discussion Findings were generally similar across age group, gender and race/ethnicity. Age group-specific, gender-specific and race/ethnicity-specific motivators and barriers were related to how commonly the motivators and barriers were identified among each group. Translation to Health Education Practice Implications for increasing physical activity among low-income culturally diverse adolescents and adults are discussed. PMID:29527247

Prenatal alcohol exposure can adversely affect brain development, although little is known about the effects of prenatal alcohol exposure on gyrification. Gyrification reflects cortical folding complexity and is a process by which the surface of the brain creates sulci and gyri. Prior studies have shown that prenatal alcohol exposure is associated with reduced gyrification in childhood, but no studies have examined adolescents. Subjects (12–16y) comprised two age-equivalent groups: 30 adolescents with histories of heavy prenatal alcohol exposure (AE) and 19 non-exposed controls (CON). A T1-weighted image was obtained for all participants. Local gyrification index (LGI) was estimated using FreeSurfer. General linear models were used to determine between group differences in LGI controlling for age and sex. Age-by-group interactions were also investigated while controlling for sex. The AE group displayed reduced LGI relative to CON in the bilateral superior parietal region, right postcentral region, and left precentral and lateral occipital regions (ps < .001). Significant age-by-group interactions were observed in the right precentral and lateral occipital regions, and in the left pars opercularis and inferior parietal regions (ps < .01). The AE group showed age-related reductions in gyrification in all regions whereas the CON group showed increased gyrification with age in the lateral occipital region only. While cross-sectional, the age-related reduction in gyrification observed in the AE group suggests alterations in cortical development throughout adolescence and provides further insight into the pathophysiology and brain maturation of adolescents prenatally exposed to alcohol.

Social Influence on Risk Perception During Adolescence

PubMed Central

Magis-Weinberg, Lucía; Speekenbrink, Maarten; Blakemore, Sarah-Jayne

2015-01-01

Adolescence is a period of life in which peer relationships become increasingly important. Adolescents have a greater likelihood of taking risks when they are with peers rather than alone. In this study, we investigated the development of social influence on risk perception from late childhood through adulthood. Five hundred and sixty-three participants rated the riskiness of everyday situations and were then informed about the ratings of a social-influence group (teenagers or adults) before rating each situation again. All age groups showed a significant social-influence effect, changing their risk ratings in the direction of the provided ratings; this social-influence effect decreased with age. Most age groups adjusted their ratings more to conform to the ratings of the adult social-influence group than to the ratings of the teenager social-influence group. Only young adolescents were more strongly influenced by the teenager social-influence group than they were by the adult social-influence group, which suggests that to early adolescents, the opinions of other teenagers about risk matter more than the opinions of adults.

2008-01-01

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

Parents’ Monitoring Knowledge Attenuates the Link Between Antisocial Friends and Adolescent Delinquent Behavior

2009-01-01

Developmental trajectories of parents’ knowledge of their adolescents’ whereabouts and activities were tested as moderators of transactional associations between friends’ antisociality and adolescent delinquent behavior. 504 adolescents (50% female) provided annual reports (from ages 12 to 16) of their parents’ knowledge and (from ages 13 to 16) their own delinquent behavior and their friends’ antisociality. Parents also reported the adolescents’ delinquent behavior. Growth mixture modeling was used to identify two sub-groups based on their monitoring knowledge growth trajectories. Adolescents in the sub-group characterized by decreasing levels of parents’ knowledge reported more delinquent behavior and more friend antisociality in early adolescence, and reported greater increases in delinquent behavior and friend antisociality from early to middle adolescence compared to adolescents in the sub-group characterized by increasing levels of parents’ knowledge. Transactional associations consistent with social influence and social selection processes also were suppressed in the increasing knowledge sub-group as compared to the decreasing knowledge sub-group.

2015-01-01

Background The aim of this study was to compare attachment styles and psychopathology in adolescent children of parents with bipolar disorder (BD) with a healthy control group. Material/Methods We studied 25 adolescents who had at least 1 parent with BD (BD group) and 28 adolescents who had no parents with BD (control group). The adolescent participants were between the ages of 12 and 17 years. We used the Adolescent Relationship Scales Questionnaire (A-RSQ) for the adolescents in the BD vs. control groups, and we used the Schedule for Affective Disorders and Schizophrenia for School-age Children – present and lifetime version (K-SADS-PL). We used the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I), Clinician Version for each parent of adolescents in the BD and control groups to rule out psychopathologies. Results Attachment styles of participants were assessed according to A-RSQ, dismissing attachment style scores of adolescents in BD group were found significantly higher compared to the healthy control group (p<0.05). As a result of the assessments, 12 adolescents (48%) out of 25 in the BD group and 5 adolescents (18%) out of 28 in the control group were given DSM-IV Axis I diagnosis, which is a statistically significant result (p<0.05). However, when psychiatric diagnoses were assessed separately, the difference was not statistically significant. Conclusions We found that the adolescent children of parents with BD have increased risk of developing mental illnesses, and that these adolescents adopt dismissing attachment styles. PMID:25877235

To identify social and behavioral factors associated with unintended pregnancy among adolescents in Russia. Cross-sectional. The investigation group consisted of 145 adolescents aged 15-19 years admitted to a youth-friendly clinic for induced abortion. The control group consisted of 77 sexually active never pregnant adolescent girls of similar age admitted for other reasons. Both groups completed a self-administered questionnaire about their occupation, educational level of their mother, family structure and socioeconomic status, relationship with their mother, sexual behavior, and substance use. Factors associated with unintended pregnancy. In the bivariate analysis pregnant adolescents tended to have a lower educational level, to live in a nonintact family, to prefer stronger alcohol drinks, and to have a younger age at sexual debut and more frequent sexual intercourse. In the log-linear model six factors appeared to be directly linked to pregnancy: mother's lower education, alcohol consumption, nonintact family structure, low academic grades, higher frequency of sexual intercourse, and lower age at sexual debut. Although the issue of unwanted pregnancy and possible ways to prevent it should be kept in mind in the psychosocial assessment of any adolescent, the results of our study suggest that some adolescents are at increased risk of unwanted pregnancy. This group includes adolescent girls with low educational attainment, living in a disrupted family, and reporting other risk behaviors. These adolescents might specially benefit from specific preventive programs to reduce the number of adverse outcomes. Copyright © 2016 North American Society for Pediatric and Adolescent Gynecology.

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

Stephenson, Rob; Simon, Calleen; Finneran, Catherine

2014-06-01

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

Playing it Safe: Legal and Clandestine Abortions Among Adolescents in Ethiopia.

The 2005 expansion of the Ethiopian abortion law provided minors access to legal abortions, yet little is known about abortion among adolescents. This paper estimates the incidence of legal and clandestine abortions and the severity of abortion-related complications among adolescent and nonadolescent women in Ethiopia in 2014. This paper uses data from three surveys: a Health Facility Survey (n = 822) to collect data on legal abortions and postabortion complications, a Health Professionals Survey (n = 82) to estimate the share of clandestine abortions that resulted in treated complications, and a Prospective Data Survey (n = 5,604) to collect data on abortion care clients. An age-specific variant of the Abortion Incidence Complications Method was used to estimate abortions by age-group. Adolescents have the lowest abortion rate among all women below age 35 (19.6 per 1,000 women). After adjusting for lower levels of sexual activity among adolescents however, we find that adolescents have the highest abortion rate among all age-groups. Adolescents also have the highest proportion (64%) of legal abortions compared with other age-groups. We find no differences in the severity of abortion-related complications between adolescent and nonadolescent women. We find no evidence that adolescents are more likely than older women to have clandestine abortions. However, the higher abortion and pregnancy rates among sexually active adolescents suggest that they face barriers in access to and use of contraceptive services. Further work is needed to address the persistence of clandestine abortions among adolescents in a context where safe and legal abortion is available.

Associations between parenting style, physical discipline, and adjustment in adolescents' reports.

PubMed

Gunnoe, Marjorie Lindner

2013-06-01

Recollections of physical discipline as absent, age-delimited (ages 2-11), or present into adolescence were associated with youths' evaluations of their mothers' and fathers' parenting styles and their own adjustment. Data were from the Portraits of American Life Study-Youth (PALS-Y) a diverse, national sample of 13- to 18-year-olds (N = 158). The modal experience of youth with authoritative parents was age-delimited spanking; the modal experience of youth with permissive parents was no spanking; the modal experience of youth with authoritarian or disengaged parents was physical discipline into adolescence. The age-delimited group reported the best adjustment (less maladjustment than the adolescent group; greater competence than both other groups). The positive association between fathers' age-delimited spanking and youths' academic rank persisted even after accounting for parenting styles. The eschewing of spanking should not be listed as a distinguishing characteristic of authoritative parenting, which was more often associated with age-delimited spanking than with zero-usage.

This study investigates whether anxiety and depressive disorder symptoms of adolescents from the general community are best described by a model that assumes they are indicative of one general factor or by a model that assumes they are two distinct disorders with parallel growth processes. Additional analyses were conducted to explore the comorbidity of adolescent anxiety and depressive disorder symptoms and the effects that adolescent anxiety and depressive disorder symptoms have on each other's symptom severity growth. Two cohorts of early (N = 923; Age range 10-15 years; Mean age = 12.4, SD = .59; Girls = 49%) and middle adolescent (N = 390; Age range 16-20 years; Mean age = 16.7, SD = .80; Girls = 57%) boys and girls from the general community were prospectively studied annually for five years. These two adolescent cohorts were divided into five groups: one group at-risk for developing a specific anxiety disorder and four additional groups of healthy adolescents that differed in age and sex. Self-reported anxiety and depressive disorder symptoms were analyzed with latent growth modeling. Comparison of the fit statistics of the two models clearly demonstrates the superiority of the distinct disorders with parallel growth processes model above the one factor model. It was also demonstrated that the initial symptom severity of either anxiety or depression is predictive of the development of the other, though in different ways for the at-risk and healthy adolescent groups. The results of this study established that the development of anxiety and depressive disorder symptoms of adolescents from the general community occurs as two distinct disorders with parallel growth processes, each with their own unique growth characteristics.

To assess the factors related to the presence of polycystic ovary syndrome (PCOS) in adolescents. This was a cross-sectional study, with female adolescents from 15 to 18 years old, divided into: group 1 (with a medical diagnosis of PCOS) and group 2 (not diagnosed with PCOS). The height-for-age index and the body mass index were used for classifying the nutritional status, and a semi-structured questionnaire was applied. The Mann-Whitney test, Fisher's exact test, Spearman correlation coefficients, and logistic regression were used. This study evaluated 485 adolescents with an average age of 16.3 ± 0.9 years old. The prevalence of PCOS was 6.2%. No difference was found between the groups regarding anthropometric parameters and period of contraceptive use; however, there were differences regarding the age at menarche (p < 0.004). Older age at menarche was a protection factor against the syndrome. An association was found between younger age at menarche and the development of the PCOS in adolescents.

Peer counseling in a culturally specific adolescent pregnancy prevention program.

PubMed

Ferguson, S L

1998-08-01

This study evaluated the effects of peer counseling in a culturally specific adolescent pregnancy prevention program for African American females. A random pretest and multiple posttest experimental and comparison group design was used to obtain data on a sample of 63 female African American adolescents, ages 12 to 16, who lived in four public housing developments. Descriptive data and tests of significance revealed that none of the participants who received peer counseling became pregnant within three months of the intervention. Findings revealed a statistically significant increase in reproductive and other self-related knowledge topics among the experimental group when comparing pretest and eight-week posttest scores. Most participants had not had sexual intercourse; the average age of sexual onset was 12 years in the experimental group and 11 years in the controls. Designing and implementing culturally specific adolescent pregnancy prevention programs for adolescents younger than age 11 and/or before sexually active seems appropriate.

Religious and national group identification in adolescence: a study among three religious groups in Mauritius.

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.

Analysis of Lyrics from Group Songwriting with Bereaved Children and Adolescents.

Fiore, Jennifer

2016-01-01

Songwriting is a group intervention that is often used to help bereaved children and adolescents express thoughts and feelings associated with grief experiences. Few studies have examined the lyrical content of songs written by bereaved children/adolescents and how thematic content may vary by age and developmental understanding of death. The purpose of this study was to determine whether experiences of songwriting and lyrical content of songs written by children and adolescents participating in a bereavement camp vary by age. Thirty-three participants, ages 6-16, were grouped according to age (child, tween, or teen) and asked to write a group song. Analysis of song lyrics was based on both inductive and deductive content analysis processes. A seven-item questionnaire was also used with the tween and teen groups to gather descriptive information about the songwriting process, including participant views on benefits, enjoyment, and preferences. Analyses revealed a total of five different themes among the three age groups, with two of the five themes present across the age groups. A majority of the participants enjoyed the songwriting process, but no clear indication of preference for verbal or written contribution was determined based on age or gender. The lyric content of the songs varied across the age groups, with the older groups providing more diverse content and demonstrating growth in their understanding of death. Providing participants both written and verbal options to contribute to the songwriting process allows for individual preferences among tweens and teens. © the American Music Therapy Association 2016.

Childhood Predictors and Adult Life Success of Adolescent Delinquency Abstainers.

2016-04-01

While much is known about adolescent delinquency, considerably less attention has been given to adolescent delinquency abstention. Understanding how or why some adolescents manage to abstain from delinquency during adolescence is informative for understanding and preventing adolescent (minor) delinquency. Using data from the Cambridge Study in Delinquent Development (N = 411 males) to compare abstainers, self-report delinquents and convicted delinquents we found five childhood factors (ages 8-10) that predicted adolescent abstention (ages 10-18). First, we find that adolescent abstainers possess characteristics opposite to those of convicted delinquents (namely, abstainers are high on honesty, conformity and family income). However, we also found that abstainers also share some childhood characteristics with convicted delinquents (namely, low popularity and low school achievement). A latent class analysis indicated that the mixed factors predicting abstention can be accounted for by two groups of abstainers: an adaptive group characterized by high honesty, and a maladaptive group characterized by low popularity and low school achievement. Further, validation of these two types of abstainers using data collected at age 48 suggested that adaptive abstainers outperform all other adolescents in general life success, whereas maladaptive abstainers only fare better than delinquent adolescents in terms of lower substance use and delinquency later in life.

Ethnic-group socioeconomic status as an indicator of community-level disadvantage: A study of overweight/obesity in Asian American adolescents.

Asian American children and adolescents are an under-investigated subpopulation in obesity research. Informed by a wide socioeconomic diversity among Asian American ethnic groups, this study explored ethnic-group socioeconomic status (SES) as an indicator of community-level disadvantage that may influence overweight/obesity in Asian American adolescents. We hypothesized that ethnic-group SES was inversely associated with overweight/obesity in Asian American adolescents. Multiple logistic regression models were fitted using a sample of 1525 Asian American adolescents ages 12-17 from pooled 2007-2012 California Health Interview Survey (CHIS) data. Age, gender, nativity, individual-level SES (income and education), and two lifestyle variables (fast food consumption and physical activity) were controlled for. We found that adolescents in high- or middle-level SES ethnic groups were far less likely to be overweight/obese than those in low-SES ethnic groups. Further, these relationships were more pronounced for foreign-born adolescents but not significant for U.S.-born adolescents. Ethnic-group SES may be a meaningful indicator of community-level socioeconomic disparities that influence the health of Asian Americans and, potentially, other populations with high proportions of immigrants of diverse socioeconomic and ethnic backgrounds.

To elucidate a possible connection between delinquency and adolescent sexual behaviours in different age groups from 14 to 20 and the role of depression therein. Data were gathered from the cross-sectional Finnish School Health Promotion Study 2010 and 2011 with 186,632 respondents. We first examined the bivariate relationship between delinquency and sexual behaviour, and then proceeded to multivariate models accounting for self-reported depression. Analyses were conducted separately for girls and boys, in seven age groups. The main outcomes were analysed by χ 2 test and logistic regression. Delinquency was connected to having experienced sexual intercourse across all age groups, and was related to reporting multiple sexual partners among sexually active adolescents, in both boys and girls, before and after controlling for depression. Delinquency and depression were independently associated with the sexual behaviours studied. Being sexually active and engaging in risky sexual behaviours are related to delinquency in the adolescent population throughout the developmental phase, even in late adolescence when being sexually active is developmentally normative. Being sexually active is further connected to depression until middle adolescence, and risky sexual behaviours across adolescence. Clinicians working with adolescents presenting with delinquent behaviour with or without depression need to address their sexual health needs.

Gender Differences in Symptom Reporting on Baseline Sport Concussion Testing Across the Youth Age Span.

Little is known regarding gender differences in concussion symptom reporting developmentally across the age span, specifically in pre-adolescent athletes. The present study asks: Do boys and girls differ in symptom reporting across the pre-adolescent to post-adolescent age span? This retrospective study utilized baseline assessments from 11,695 10-22 year-old athletes assigned to 3 independent groups: Pre-adolescent 10-12 year olds (n = 1,367; 12%), Adolescent 13-17 year olds (n = 2,974; 25%), and Late Adolescent 18-22 year olds (n = 7,354; 63%). Males represented 60% of the sample. Baseline ImPACT composite scores and Post-Concussion Symptom Scale scores (Total, Physical, Cognitive, Emotional, Sleep) were analyzed for the effects of age and gender. Statistically significant main effects were found for age and gender on all ImPACT composites, Total Symptoms, and Symptom factors. Significant interaction effects were noted between age and gender for all ImPACT composites, Total Symptoms, and Symptom factors. Total Symptoms and all Symptom factors were highest in adolescents (ages 13-17) for males and females. In the 10-12 age group, females displayed lower Total Symptoms, Physical, and Sleep factors than males. The notion of females being more likely than males to report symptoms does not appear to apply across the developmental age span, particularly prior to adolescence. Females show greater emotional endorsement across the youth age span (10-22 years). Adolescence (13-17 years) appears to be a time of increased symptomatology that may lessen after the age of 18. © The Author(s) 2018. Published by Oxford University Press. All rights reserved.

The development of Israeli children's images of Jews and Arabs and their expression in human figure drawings.

PubMed

Teichman, Y

2001-11-01

The development of images of "a Jew" and "an Arab" in Jewish Israeli children who were 4-15 years of age was investigated by means of human figure drawings followed by the administration of questionnaires. The drawings were scored on structural and thematic variables. The questionnaires assessed beliefs and intentions. The hypotheses predicted a differential perception of in- and out-groups and peaks in negativity toward the out-group at preschool age and in early adolescence. Results indicate that, irrespective of age, Jewish Israeli children have generalized images of the two ethnic groups. Preschoolers expressed both positive biases toward the in-group and negativism toward the out-group. and early adolescents manifested mainly negative biases toward the out-group. Children in middle childhood and mid-adolescents manifested reductions in both in-group favoritism and out-group negativity.

Acculturation or development? Autonomy expectations among ethnic German immigrant adolescents and their native German age-mates.

2012-01-01

This longitudinal study compared immigrant and native adolescents' expectations concerning the timing of conventional socially acceptable and oppositional less socially acceptable forms of autonomy. Based on normative development and a collectivist background among immigrants, both developmental and acculturative change was expected. The sample consisted of 523 ethnic German immigrants from the former Soviet Union and 475 native German adolescents, both groups divided into an early (age 12.5years) and a late (age 16years) adolescent group. Results revealed more developmental than acculturative change, as immigrants and natives mostly showed a similar rate of change in autonomy expectations. Acculturative change was found only for oppositional autonomy among late adolescent immigrants, whose later expectations approached those of their native age-mates over time. © 2012 The Authors.

Physical activity has been shown to have a positive effect on bone metabolism among adolescents. The objective of this study was to determine the effect of swimming on bone metabolism during adolescence. Swimming, as a non-weight-bearing sport, has been considered to be insignificant in the maintenance of bone mass. We studied whether swimming is associated with a higher peak bone mass. Forty swimmers (males aged 10-17 years and females aged 9-16 years) were studied. The control group consisted of the same number of adolescents aged between 10-16 years who did not swim; distribution of male and female gender was similar in the non-swimming control group compared to the swimming group. Adolescents were matched for age, gender and pubertal stages based on Tanner staging. All subjects underwent combined measurement of bone mineral metabolism by dual-energy X-ray absorptiometry of total body calcium content, and specific biochemical markers of turnover including osteocalcin, calcium, phosphorus and alkaline phosphatase. Bone age (determined by Greulich and Pyle's Radiographic Atlas of Skeletal Development of the Hand and Wrist), weight, height, ideal body weight, ideal body weight ratio, body mass index, Tanner classification (rated by examiner), diet, history of tobacco and alcohol exposure, exercise, socioeconomic status and history of chronic illness and medications were recorded to evaluate potential mediators that would affect bone metabolism. Tanner staging was used to assess puberty, and diet was evaluated based on reported consumption of milk, yogurt and cheese and cola/caffeine beverage consumption daily. There was significant difference in bone mineral content between adolescent male swimmers and the control group males. Consumption of cola beverages were significantly higher among the control group compared with the swimmer group. Ideal body weight ratio was significantly high among the female control group compared with female swimmers. Milk consumption was significantly higher for both male and female swimmer groups, whereas yogurt consumption was only significantly higher in the male swimmer group compared with control group. These results indicate that a highly active nonimpact sport such as swimming may lead to increased bone mineral content only for male swimmers. However, dietary behaviors may be more important than swimming on bone metabolism among adolescents.

We assessed the accuracy of the French version of the Autism Spectrum Quotient (AQ) in adolescents with Asperger syndrome (AS) and high-functioning autism (HFA) compared to healthy controls and adolescents with psychiatric disorders (PDs). Three groups of adolescents, aged 11-18, were assessed: 116 with AS/HFA (93 with IQ ≥ 85 and 20 with 70 ≤ IQ < 85), 39 with other PDs, and 199 healthy controls. The AS/HFA group scored significantly higher than the healthy control and PD groups. A cut-off score of 26 was used to differentiate the autism group from healthy controls with 0.89 sensitivity and 0.98 specificity. Scores did not vary by age or sex.

Ecological perspectives stress the importance of environmental predictors of adolescent alcohol use, yet little research has examined such predictors among immigrant adolescents. This study examines parental, peer and school predictors of alcohol drinking (casual drinking, binge drinking and drunkenness) among Israeli-born adolescents and first and second generation adolescent immigrants from the Former Soviet Union (FSU) and Ethiopia in Israel. The study uses data from the 2010 to 2011 Israeli Health Behaviors of School age Children (HBSC) survey and includes a representative sample of 3059 adolescents, aged 11-17. Differences between the groups for drinking were examined using Pearson's chi square. Logistic regression models were used to examine group specific predictors of drinking. First generation FSU and both Ethiopian groups reported higher levels of binge drinking and drunkenness than Israeli-born adolescents. All immigrant groups reported lower levels of parental monitoring than native born adolescents; both first generation groups reported difficulties talking to parents; and first generation FSU and second generation Ethiopian adolescents reported greater time with friends. Group specific logistic regression models suggest that while parent, peer and school variables all predicted alcohol use among Israeli adolescents, only time spent with peers consistently predicted immigrant alcohol use. Findings highlight specific vulnerability of first generation FSU and second generation Ethiopian adolescents to high levels of drinking and the salience of time spent with peers as predicting immigrant adolescent drinking patterns. They suggest that drinking patterns must be understood in relation to country of origin and immigration experience of a particular group. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Quality Improvement to Immunization Coverage in Primary Care Measured in Medical Record and Population-Based Registry Data.

PubMed

Harder, Valerie S; Barry, Sara E; Ahrens, Bridget; Davis, Wendy S; Shaw, Judith S

Despite the proven benefits of immunizations, coverage remains low in many states, including Vermont. This study measured the impact of a quality improvement (QI) project on immunization coverage in childhood, school-age, and adolescent groups. In 2013, a total of 20 primary care practices completed a 7-month QI project aimed to increase immunization coverage among early childhood (29-33 months), school-age (6 years), and adolescent (13 years) age groups. For this study, we examined random cross-sectional medical record reviews from 12 of the 20 practices within each age group in 2012, 2013, and 2014 to measure improvement in immunization coverage over time using chi-squared tests. We repeated these analyses on population-level data from Vermont's immunization registry for the 12 practices in each age group each year. We used difference-in-differences regressions in the immunization registry data to compare improvements over time between the 12 practices and those not participating in QI. Immunization coverage increased over 3 years for all ages and all immunization series (P ≤ .009) except one, as measured by medical record review. Registry results aligned partially with medical record review with increases in early childhood and adolescent series over time (P ≤ .012). Notably, the adolescent immunization series completion, including human papillomavirus, increased more than in the comparison practices (P = .037). Medical record review indicated that QI efforts led to increases in immunization coverage in pediatric primary care. Results were partially validated in the immunization registry particularly among early childhood and adolescent groups, with a population-level impact of the intervention among adolescents.

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

Caring for the adolescent (13-18 years of age) with an ostomy presents multiple challenges. The purpose of this article is to provide strategies to assist the WOC nurse in minimizing the potential impact on growth and development for this age group with an ostomy. This is relevant to the WOC nurse since it is estimated that between 6% and 14% of all adolescents have symptoms of irritable bowel disease, and many will require an ostomy. Thus the WOC nurse will be called upon to provide care to this age group. This article discusses normal adolescent growth and development and provides strategies to support the normal growth and development.

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

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

The 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.

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

2003-01-01

Study objective: This paper describes and attempts to explain the association between occupational level of the father and high alcohol consumption among a cohort of New Zealand adolescents from age 11 to 21. Design: Data were obtained from the longitudinal Dunedin multidisciplinary health and development study. At each measurement wave, those who then belonged to the quartile that reported the highest usual amount of alcohol consumed on a typical drinking occasion were categorised as high alcohol consumers. Potential predictors of high alcohol consumption included environmental factors, individual factors, and educational achievement measured at age 9, 11, or 13. Longitudinal logistic GEE analyses described and explained the relation between father's occupation and adolescent alcohol consumption. Setting: Dunedin, New Zealand. Participants: About 1000 children were followed up from birth in 1972 until adulthood. Main results: A significant association between fathers' occupation and adolescent alcohol consumption emerged at age 15. Overall adolescents from the lowest occupational group had almost twice the odds of being a large consumer than the highest occupational group. The association between father's occupation and high alcohol consumption during adolescence was explained by the higher prevalence of familial alcohol problems and friends approving of alcohol consumption, lower intelligence scores, and lower parental attachment among adolescents from lower occupational groups. Conclusions: Socioeconomic background affects adolescent alcohol consumption substantially. This probably contributes to cumulation of disadvantage. Prevention programmes should focus on adolescents from lower socioeconomic groups and make healthier choices the easier choices by means of environmental change. PMID:12933777

Children and adolescents who sell sex: a community study.

PubMed

Pedersen, Willy; Hegna, Kristinn

2003-01-01

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

2014-01-01

The paper examines recent time trends, explores potentially influential background factors and discusses prevention strategies of pregnancy among girls under 15 years of age in Japan. Using Japanese government data, we first analyzed time trends of early adolescence (<15 years of age) abortion, live birth and child sexual abuse from 2003 to 2010. Second, we analyzed ecological correlations of early adolescent pregnancy (abortion, live birth and stillbirth) with pregnancy in other age groups, child sexual abuse, and indicators of juvenile victimization and juvenile delinquency, using prefectural data. We found that rates of both abortion and live birth in early adolescents have increased since 2005 (annual percent change 5.3% and 2.3%, respectively), despite declining rates in older age groups. The abortion ratio in early adolescence remained the highest among all age groups in Japan. The early adolescent pregnancy rate showed significant correlation with the rates of juvenile victimization of welfare crimes (obscenity, alcohol drinking, smoking and drug use) (Spearman's rank correlation coefficient [rs] = 0.42, P = 0.00) and juvenile delinquency among junior high school students (12-14 years of age) (rs = 0.69, P = 0.00). The observed rise in rates of abortion, live birth and child sexual abuse among early adolescents along with strong ecological correlations of their pregnancy rate with juvenile victimization and delinquency indicators suggests that epidemiological investigation and public health programs at the individual and community levels are needed to address the complex social roots of these trends and to produce effective improvements in early adolescent reproductive health. © 2013 The Authors.

To investigate differences in sexual risk factors between adolescent girls reporting similar-aged or older sex partners. Adolescent girls are at significant risk of heterosexual-acquired HIV infection and other long-term reproductive health issues. Sexual partner age discordance in teen girls has been correlated with STIs, lack of protection, multiple partners and earlier age of sexual transition. A descriptive study comparing girls currently involved with age-discordant partners to those with similar-aged partners. Two-sample t-test for continuous variables and chi-squared test or Fisher's exact test for categorical variables were used to compare groups. Baseline data from 738 sexually active, urban, adolescent girls aged 15-19 were analysed to determine which behaviours were more likely to occur in girls with older partners. Data were collected as part of a gender-specific HIV-prevention intervention in a randomised controlled trial (RCT) tailored to adolescent girls. Multiple reported sexual risk behaviours were found to significantly differ between the two groups at baseline. Overall, girls with older partners had more episodes of sexual instances (vaginal, anal and oral). Specific sexual risk behaviours were found to be statistically significant between the two groups. Girls with older partners started having sex at earlier ages, had more lifetime sexual partners, higher incidents of STIs and were reluctant to discuss using condoms with their partners. Girls with similar-aged partners were less willing to engage in risky sexual behaviours. Findings from this investigation support data from other studies. Relationships with older male partners place adolescent girls at increased risk of HIV/STIs and unintended pregnancy. Adolescent girls in age-discordant relationships are at risk of immediate and long-term sexual health morbidities. Identifying girls who are at increased risk by asking tailored questions will enable nurses to recommend appropriate diagnostics for this population and provide age-specific counselling. © 2013 John Wiley & Sons Ltd.

2013-09-24

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. 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. 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. 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 support parents and to impede availability of alcoholic beverages for adolescents/children younger than 18 years.

Narrative means to manage responsibility in life narratives across adolescence.

De Silveira, Cybèle; Habermas, Tilmann

2011-01-01

Adolescence is a passage from dependence to adult responsibility. Alongside identity development, social-cognitive development, and the ability to construct a life story, adolescents become increasingly aware of both their potential responsibility in an expanded sphere of life and of complex, contextual influences on their lives. This was partially tested in a cross-sectional study, both in terms of linguistic means and content expressed in life narratives. Indicators were defined for narrative agency, grading of responsibility, serendipity, and turning points, and tested for age differences in relative frequencies in 102 life narratives from age groups of 8, 12, 16, and 20 years, balanced for gender. Narrative grading of responsibility, serendipity, and turning points increased throughout adolescence. The relative frequency of narrative agency, in contrast, remained constant across age groups. Results are interpreted in the context of adolescent development of narrative identity.

Recommendations on Arresting Global Health Challenges Facing Adolescents and Young Adults.

Lassi, Zohra S; Salam, Rehana A; Bhutta, Zulfiqar A

The health challenges faced by young people are more complex than adults and can compromise their full growth and development. Attention must be paid to the health of this age group, yet adolescents and youth remain largely invisible and often disappear from the major global datasets. The aim of this paper is to discuss the global health challenges faced by adolescents and youth, global legislations and guidelines pertaining to this particular age group, recommendations to arrest these challenges, and research priorities. Major direct and indirect global health risks faced by adolescents include early pregnancy and childbirth, femicide, honor killing, female genital mutilation, nutritional habits and choices, social media, and peer pressure. There are no standard legal age cut-offs for adulthood; rather, the age varies for different activities, such as age of consent or the minimum age that young people can legally work, leave school, drive, buy alcohol, marry, be held accountable for criminal action, and make medical decisions. This reflects the fact that the existing systems and structures are focused on either children or adults, with very few investments and interventions directed specifically to young people. Existing legislation and guidelines need transformation to bring about a specific focus on adolescents in the domains of substance use and sexual behaviors, and the capacity for adolescent learning should be exploited through graduated legal and policy frameworks. Sustainable development goals provide an opportunity to target this neglected and vulnerable age group. A multisectoral approach is needed to bring about healthy change and address the challenges faced by adolescents and youth, from modifications at a broader legislative and policy level to ground-level (community-level) implementations.

Subjective age generally refers to the age that one feels. In a cross-sectional questionnaire study of 245 adolescents ages 10-14 years, we examined (a) whether, and when, a cross-over in subjective age occurs, (b) differences in subjective age among pubertal timing groups, (c) correlations between subjective age and each of desired age and five…

To understand the problems faced and the difference in knowledge, attitude and practice of young people across the age group of 10-24 y on reproductive and sexual health issues and to get their suggestions regarding adolescent care services. This cross sectional community survey involving three districts in Kerala was conducted among adolescents and young adults of 10-24 y using a population proportion to sample size technique. The main problems faced by the young people between 10 and 24 y of age were financial, substance abuse in family, poor academic performance, difference of opinion, disease in self/family, mental problems, lack of talent, strict parents, difficulty in mingling, love failure, broken family, loneliness and problems at school/office in the descending order. As the age advances higher percentage of both boys (43.4%) and girls (61.7%) discuss reproductive sexual health issues among themselves. There was a statistically significant difference in personal hygiene practices like changing napkins/cloths more than once a day (94.3%), cleaning genital organs with soap every day (71.7%), washing after urination (69.2%), washing from front to back after defecation (62.2%) and washing hands with soap after defecation (73.2%) between 10-14, 15-19, and 20-24 y age group with higher percentages in the older groups. In order to make the service more useful, more of the older group participants suggested giving information on adolescent services to parents, adolescents and society as a whole by creating better societal acceptance and keeping confidentiality in service delivery. This study has shown an overall inadequacy in reproductive health knowledge in all age groups, but increasing knowledge gain and better attitude and practices on reproductive and sexual health as the age increases. The suggestions made by the group regarding need for adolescent reproductive sexual health (ARSH) and counseling services with privacy and confidentiality ensured, is useful for planning ARSH services under National Rural Health Mission.

Global scale up of anti-retroviral therapy (ART) has led to expansion of HIV treatment and prevention across sub-Saharan Africa. However, age and gender-specific disparities persist leading to failures in fulfillment of Sustainability Development Goals, including SDG3 (achieving healthy lives and wellbeing for all, at all ages) and SDG5 (gender equality). We assessed ART initiation and adherence, loss to follow-up, all-cause death and early death, according to SDG3 and SDG5 indicators among a cohort of HIV-infected children and adolescents enrolled in care in Dar-es-Salaam, Tanzania METHODS: SDG3 indicators included young (<5 years) and older paediatric children (5 to <10 years), early adolescent (10 to <15 years) and late adolescent (15 to <20 years) age group divisions and the SDG5 indicator was gender. Associations of age group and gender with ART initiation, loss to follow-up and all-cause death, were analysed using Cox proportional hazards regression and with adherence, using generalized estimating equations (GEE) with the Poisson distribution. Associations of age group and gender with early death were analysed, using log-Poisson regression with empirical variance. A total of 18,315 enrollees with at least one clinic visit were included in this cohort study. Of these 7238 (40%) were young paediatric , 4169 (23%) older paediatric, 2922 (16%) early adolescent and 3986 (22%) late adolescent patients at enrolment. Just over half of paediatric and early adolescents and around four fifths of the late adolescents were female. Young paediatric patients were at greater risk of early death, being almost twice as likely to die within 90 days. Males were at greater risk of early death once initiated on ART (HR 1.35, 95% CI 1.09, 1.66)), while females in late adolescence were at greatest risk of late death (HR 2.44 [1.60, 3.74] <0.01). Late adolescents demonstrated greater non-engagement in care (RR 1.21 (95% CI 1.16, 1.26)). Among both males and females, early paediatric and late adolescent groups experienced significantly greater loss to follow-up. These findings highlight equity concerns critical to the fulfillment of SDG3 and SDG5 within services for children and adolescents living with HIV in sub-Saharan Africa. Young paediatric and late adolescent age groups were at increased risk of late diagnosis, early death, delayed treatment initiation and loss of continuity of care. Males were more likely to die earlier. Special attention to SDG3 and SDG5 disparities for children and adolescents living with HIV will be critical for fulfillment of the 2030 SDG agenda. © 2018 The Authors.

To analyze, in a population of adolescents in school, the relationship between psychosomatic symptoms and the perception of health-related quality of life (HRQoL), differentiating by gender and age group. Transversal study. Five Secondary Schools. Eight hundred and forty four adolescents between the ages of 15 and 18 in secondary school. HRQoL using KIDSCREEN-52 and psychosomatic symptoms with the psychosomatic problems scale (PSP). Girls and adolescents aged 17-18 years presented significantly higher psychosomatic symptoms, both groups also scored worse in all dimensions of HRQoL, although only the dimensions related to physical and mental wellness, mood and stress reached significance. All psychosomatic symptoms were inversely associated with the ten dimensions of KIDSCREEN-52. The regression models showed that sadness, concentrating difficulties and sleeping difficulties were the predictors of worse HRQoL in both sexes and age groups and these variables explained between 30 and 41% of the HRQoL variance of the adolescents. Psychosomatic symptoms are frequent especially in girls and in older adolescents and predictors of worse HRQoL. It is important to distinguish them from medical conditions to avoid unnecessary interventions. As expressions of emotional discomfort they must be evaluated and treated in an integral way because they interfere with daily life and increase the vulnerability proper of adolescence.

The purpose of this study was to develop and pilot-test an innovative behavioral intervention in adolescents with type 1 diabetes mellitus (T1DM) incorporating structured care of a pet to improve glycemic control. Twenty-eight adolescents with A1C > 8.5% (69 mmol/mol) were randomly assigned to either the intervention group (care of a Betta splendens pet fish) or the control group (usual care). Adolescents in the intervention group were given instructions to associate daily and weekly fish care duties with diabetes self-management tasks, including blood glucose testing and parent-adolescent communication. After 3 months, the participants in the intervention group exhibited a statistically significant decrease in A1C level (-0.5%) compared with their peers in the control group, who had an increase in A1C level (0.8%) (P = .04). The younger adolescents (10-13 years of age) demonstrated a greater response to the intervention, which was statistically significant (-1.5% vs 0.6%, P = .04), compared with the older adolescents (14-17 years of age). Structured care of a pet fish can improve glycemic control in adolescents with T1DM, likely by providing cues to perform diabetes self-management behaviors. © 2015 The Author(s).

Youth within the juvenile justice system report higher rates of mental illnesses than their peers. This study tested whether institutional confinement increases levels of depression and anxiety among male adolescents. We examined heterogeneous trajectories of depression and anxiety from ages 11 to 14 for 510 male adolescents. Youths who were first placed in custody at age 15 (treatment group) were matched with control boys (no official arrest or reported confinement during adolescence) within each trajectory group using a propensity score matching procedure. Matches were found for 37 pairs for depression and 34 pairs for anxiety. There were no significant differences between the confined and control groups in levels of depression or anxiety at age 16. More research is needed to identify aspects of the juvenile justice system that may positively or negatively affect youth’s mental health status. PMID:23504068

Self-perception, self-regulation and metacognition in adolescents with intellectual disability.

2014-06-01

This study compares self-perception of competences in 28 typically developing children (TD) aged 7-9 years and 32 adolescents with intellectual disability (ID) aged 11-16 years in special school, matched for mental age (MA). The links between self-perception, self-regulation in problem-solving and metacognition are investigated. Overall self-perception and self-perception of competences by domain do not differ significantly between the two groups. Self-perception of competences in specific domains, self-regulation and metacognition vary depending on MA and verbal comprehension in the two groups. ID adolescents attribute more importance to social acceptance than TD children. In both groups, positive links are identified between self-perception and importance attributed to domains. Performance, self-regulation and metacognition are lower in ID adolescents than in TD children. Positive links are obtained between self-perception of competences in specific domains and certain self-regulatory and metacognitive strategies, although these links differ in the two groups.

Determinants of binge drinking in a permissive environment: focus group interviews with Dutch adolescents and parents

PubMed Central

2013-01-01

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 support parents and to impede availability of alcoholic beverages for adolescents/children younger than 18 years.

2017-05-01

Adolescent sexual development is not the same across the board, and can be seen as both normative as well as risky behavior, depending on factors such as age of onset and number of partners. This longitudinal study identified developmental trajectories of annual number of sexual partners from adolescence to emerging adulthood and their antecedents. From the ages of 16-22, 332 participants (60.8 % females) annually reported their number of sexual partners. Measures of adolescent and family characteristics taken at ages 13-15 were used as predictors. Group-based modeling identified four trajectory groups: the abstainers group (9.1 %), low-increasing group (30.6 %), medium-increasing group (53.0 %), and multiple-partners group (7.3 %). Multinomial logistical regressions indicated that better social competence increased chances of belonging to the multiple-partners group as compared to the abstainers and low-increasing groups, and more substance use predicted membership in the multiple-partners group as compared to the abstainers group. Moreover, females were overrepresented in the low-increasing and medium-increasing groups. These results imply a greater diversity in sexual development than proposed in the literature and highlight the importance of identifying the strengths and competencies associated with healthy sexual development along with the early risk factors.

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

To assess the impact of a tiered patient immunization navigator intervention (immunization tracking, reminder/recall, and outreach) on improving immunization and preventive care visit rates in urban adolescents. Randomized clinical trial allocating adolescents (aged 11-15 years) to intervention vs standard of care control. Eight primary care practices. Population-based sample of adolescents (N = 7546). Immunization navigators at each practice implemented a tiered protocol: immunization tracking, telephone or mail reminder/recall, and home visits if participants remained unimmunized or behind on preventive care visits. Immunization rates at study end. Secondary outcomes were preventive care visit rates during the previous 12 months and costs. The intervention and control groups were similar at baseline for demographics (mean age, 13.5 years; 63% black, 14% white, and 23% Hispanic adolescents; and 74% receiving Medicaid), immunization rates, and preventive care visit rates. Immunization rates at the end of the study were 44.7% for the intervention group and 32.4% for the control group (adjusted risk ratio, 1.4; 95% confidence interval, 1.3-1.5); preventive care visit rates were 68.0% for the intervention group and 55.2% for the control group (1.2; 1.2-1.3). Findings were similar across practices, sexes, ages, and insurance providers. The number needed to treat for immunizations and preventive care visits was 9. The intervention cost was $3.81 per adolescent per month; the cost per additional adolescent fully vaccinated was $465, and the cost per additional adolescent receiving a preventive care visit was $417. A tiered tracking, reminder/recall, and outreach intervention improved immunization and preventive care visit rates in urban adolescents. clinicaltrials.gov Identifier: NCT00581347.

2015-01-01

Being bullied is a well-recognized trauma for adolescents. Bullying can best be understood through an ecological framework since bullying or being bullied involves risk factors at multiple contextual levels. The purpose of the study was to identify the risk and protective factors that best differentiate groups along with the outcome variable of interest (being bullied) using Classification and Regression Tree (CART) analysis. The study used the Health Behavior in School-Aged Children (HBSC) data collected from a nationally representative sample of students in grades six through ten during the 2005–2006 school years. This study identified that for adolescents 12 and younger, lower parental support is a critical risk factor associated with bullying and among those 13 to 14 with lower parent support, adolescent with higher academic pressure reported experiencing more bullying. For the older group of adolescents (aged 15 and older), school related factors were identified to increase the risk level of being bullied. There was a critical age (15 years old) for implementing victimization interventions to reduce the damage from being bullied. Service providers working with adolescents aged 14 and less should focus more on family-oriented intervention and those working with adolescents aged 15 and more should offer peer- or school-related interventions.

Purpose Although the contribution of physique and body composition in soccer performance was recognized, these parameters of physical fitness were not well-studied in adolescent players. Aim of this study was to investigate physique and body composition across adolescence. Methods Male adolescents (N=297 aged 12.01–20.98 y), classified into nine one-year age-groups, child (control group, N=16 aged 7.34–11.97 y) and adult players (control group, N=29 aged 21.01–31.59 y), all members of competitive soccer clubs, performed a series of anthropometric measures (body mass, height, skinfolds, circumferences and girths), from which body mass index (BMI), percentage of body fat (BF%), fat mass (FM), fat free mass (FFM) and somatotype (Heath-Carter method) were calculated. Results Age had a positive association with FM (r=0.2, P<0.001) and FFM (r=0.68, P<0.001), and a negative association with BF (r=−0.12, P=0.047). Somatotype components changed across adolescence as well; age was linked to endomorphy (r=−0.17, P=0.005), mesomorphy (r=0.14, P=0.019) and ectomorphy (r=−0.17, P=0.004). Compared with age-matched general population, participants exhibited equal body mass, higher stature, lower body mass index and lower BF. Conclusion During adolescence, soccer players presented significant differences in terms of body composition and physique. Thus, these findings could be employed by coaches and fitness trainers engaged in soccer training in the context of physical fitness assessment and talent identification. PMID:22375222

This study investigated group hypnotizability in 167 adolescents (ages 13-17) in an inpatient behavioral healthcare setting through use of the Waterloo-Stanford Group Scale, Form C. It also investigated the influence of hypnotic inductions on group hypnotizability. Adolescents were randomly assigned to either a group session of hypnosis (n = 84) with a hypnotic induction or a comparison "no-induction" group (n = 83) that received identical suggestions without a hypnotic induction. Adolescents' imaginative absorption and dissociation were measured to examine their influence on hypnotizability. A between-group comparison showed the induction condition had a significantly higher score than the no-induction group on both behavioral and subjective measures of hypnotizability.

The effect of labour on somatotype of males during the adolescent growth period.

2008-01-01

Although the effect of labour and physical stress on the height and weight of growing children is relatively well known, rather limited information concerning the influences of the work environment on the physique of working children and adolescents is available. The purpose of this study was to increase our knowledge of the effects of mechanical stress on the human physique via somatotype during the adolescent growth period. Anthropometric measurements of 509 male apprentices aged 13.50-18.49 years and measurements of 451 nonworking youth (control group) of the same age group were taken. The members of both groups were from the lower socioeconomic strata and had similar living conditions. The apprentices were working an average of 11h per day in vocations requiring intense physical effort. The subjects were somatotyped using the Heath-Carter anthropometric protocol. The overall mean somatotypes were 2.3-4.4-3.3 for working adolescents, and 2.5-3.9-3.6 for the nonworking controls. A one-way multivariate analysis of variance (MANOVA) indicated significant differences between the groups. Working adolescents were more mesomorphic and less ectomorphic than their nonworking peers. In both groups, endomorphy decreased with age up to age 15; then remained stable for the labourers but increased for the nonworking peers. In both groups, mesomorphy was stable, but decreased with ectomorphy. These results indicate that physical stress not only causes retardation in linear growth, but also produces changes in human physique during the growth period.

To describe the prevalence of anemia and con-sumption of iron rich groups among Mexican children and adolescents who participated in the Halfway National Health and Nutrition Survey, 2016. Our study sample included children and adolescents who provided full capillary hemoglobin data. Anemia was defined accord-ing to WHO criteria. Logistic regression models were used to explore the association among consumption of iron-rich food groups, sociodemographic characteristics and anemia. In 2016, the prevalence of anemia was 26.9% in children aged 1 to 4 years old, 12.5% in those aged 5 to 11, and 9.6% in adolescents aged 12 to 19 years. Rates were the highest among females who lived in the southern and central parts of Mexico, belonged to an indigenous ethnic group and fell within the first tercile of the Household Wealth Index. Consumption of beef by preschoolers and viscera by ado-lescents was associated with lower risk for anemia; higher risk was associated with consumption of Liconsa milk and non-heme iron by preschoolers. Anemia is highly prevalent in Mexican children and adolescents, affect-ing mainly the poorest and youngest populations. Sources of heme iron are the principal dietary factor associated with low risk for anemia.

Youths with intellectual disabilities (ID) exhibit low levels of physical activity, but the underlying contributors to behavior are unclear. We compared physical activity enjoyment, perceived barriers, beliefs, and self-efficacy among adolescents with ID and typically developing (TD) adolescents. A questionnaire was administered to 38 adolescents with ID (mean age, 16.8 years) and 60 TD adolescents (mean age, 15.3 years). Of the original 33 questionnaire items, 23 met the test-retest reliability criteria and were included in the group comparisons. Fewer adolescents with ID reported that they have someone with whom to do physical activity (64% vs 93%: P < .001), and a greater percentage of adolescents with ID perceived that physical activities were too hard to learn (41% vs 0%; P < .001). Fewer adolescents with ID believed that physical activity would be good for their health (92% vs 100%; P = .05). More adolescents with ID reported a dislike of individual physical activities (P = .02). A large percentage of adolescents with ID (84%) responded that they were good at doing physical activities, but the difference between groups was only of borderline significance (95% of TD adolescents, P = .06). Adolescents shared many of the same perceptions about physical activity, but some important differences between groups were identified.

Background Worry is a common feature across many anxiety disorders. It is important to understand how and when worry presents from childhood to adolescence to prevent long-term negative outcomes. However, most of the existing studies that examine the relationship between worry and anxiety disorders utilize adult samples. Aims The present study aimed to assess the level of worry in children and adolescents and how relationships between worry and symptoms of separation anxiety disorder (SAD) and social anxiety disorder (Soc) may present differently at different ages. Method 127 children (age 8–12) and adolescents (age 13–18), diagnosed with any anxiety disorder, presenting at a child anxiety outpatient clinic, completed measures of worry, anxiety, and depression. Results Worry scores did not differ by age group. Soc symptoms were significantly correlated with worry in both age groups; however, SAD symptoms were only significantly correlated with worry in younger participants. After the inclusion of covariates, SAD symptoms but not Soc symptoms remained significant in the regression model with younger children, and Soc symptoms remained significant in the regression model with older children. Conclusions The finding that worry was comparable in both groups lends support for worry as a stable construct associated with anxiety disorders throughout late childhood and early adolescence.

2013-01-01

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

Non-suicidal self-injury (NSSI) is a symptom of borderline personality disorder (BPD). However, NSSI often occurs independently of BPD. Altered neural processing of social exclusion has been shown in adolescents with NSSI and adults with BPD with additional alterations during social inclusion in BPD patients. Aims of this study were to investigate differences in neural processing of social inclusion and exclusion situations between adolescents with NSSI and young adults with BPD and NSSI. Using fMRI, neural processing of positive and negative social situations (paradigm: "Cyberball") was explored. Participants were 14 adolescents with NSSI, but without BPD (M age  = 15.4; SD = 1.9), 15 adults with BPD and NSSI (M age  = 23.3; SD = 4.1), as well as 15 healthy adolescents (M age  = 14.5; SD = 1.7), and 16 healthy adults (M age  = 23.2; SD = 4.4). Behavioral results showed enhanced feelings of social exclusion in both patient groups as compared to healthy controls but only the NSSI group showed enhanced activation during social exclusion versus inclusion compared to the other groups. While both NSSI and BPD groups showed enhanced activation in the ventral anterior cingulate cortex during social exclusion as compared to their age-matched controls, enhanced activation during social inclusion as compared to a passive watching condition was mainly observed in the BPD group in the dorsolateral and dorsomedial prefrontal cortex, and the anterior insula. While neural processing of social exclusion was pronounced in adolescents with NSSI, BPD patients also showed increased activity in a per se positive social situation. These results might point toward a higher responsiveness to social exclusion in adolescents with NSSI, which might then develop into a generalized increased sensitivity to all kinds of social situations in adults with BPD.

The Integrated Food Security Program (Programa Integrado de Seguridad Alimentaria [PISA]) implemented a campaign to promote weekly multimicronutrient supplementation among women and adolescent girls of childbearing age and children under 5 years of age. To assess the impact of the campaign on the growth of children and on anemia among children and among women and adolescent girls of childbearing age. Weekly multimicronutrient supplementation was provided for 8 weeks. Weights, heights, and hemoglobin concentrations were assessed at the beginning and end of the campaign. Although supplementation did not significantly increase the hemoglobin concentrations of children (p = .80) or women and adolescent girls (p = .65) in the intervention group, the hemoglobin concentrations of the comparison groups were significantly lower after 8 weeks (p = .001 for children and p = .03 for women and adolescent girls). Furthermore, the percentage of anemic children in the comparison group increased significantly (p <.001), and the final value was significantly higher than that for the intervention group (p = .004). There were no significant effects of weekly multimicronutrient supplementation on the growth of children, but the study was too short to reliably determine any effects on growth.

Little is known about age-related differences in risk factors for cigarette smoking initiation. We identified predictors of initiation in early, middle, and late adolescence from among sociodemographic factors, indicators of smoking in the social environment, psychological characteristics, lifestyle indicators, and perceived need for cigarettes. Data were drawn from a longitudinal study of 1,801 children recruited at age 10-11 years from 29 elementary schools in Montreal, Canada. Multivariable logistic regression within a generalized estimating equations framework was used to identify predictors among never smokers across three 2-year windows: age 11-13 years (n = 1,221); age 13-15 years (n = 737); and age 15-17 years (n = 690). Among the 18 risk factors investigated, two differed across age. Friends' smoking, a strong risk factor in early adolescence (odds ratio [95% confidence interval] = 5.78 [3.90-8.58]), lost potency in late adolescence (1.83 [1.31-2.57]). Depressive symptoms, a risk factor in early and middle adolescence (1.60 [1.26-2.02] and 1.92 [1.45-2.54], respectively), were inversely associated in late adolescence (.76 [.58-1.00]). Sex, TV viewing, and weight-related goals were not associated with initiation at any age. All other factors were significant in two or three age groups. Most risk factors for smoking initiation were stable across age. Tobacco control interventions may be robust for risk factors across age groups and may not need adjustment. At all ages, interventions should focus on eliminating smoking in the social environment and on reducing the availability of tobacco products.

2011-02-01

The measurement technique for ulnar variance in the adolescent population has not been well established. The purpose of this study was to assess the reliability of a standard ulnar variance assessment in the adolescent population. Four orthopedic surgeons measured 138 adolescent wrist radiographs for ulnar variance using a standard technique. There were 62 male and 76 female radiographs obtained in a standardized fashion for subjects aged 12 to 18 years. Skeletal age was used for analysis. We determined mean variance and assessed for differences related to age and gender. We also determined the interrater reliability. The mean variance was -0.7 mm for boys and -0.4 mm for girls; there was no significant difference between the 2 groups overall. When subdivided by age and gender, the younger group (≤ 15 y of age) was significantly less negative for girls (boys, -0.8 mm and girls, -0.3 mm, p < .05). There was no significant difference between boys and girls in the older group. The greatest difference between any 2 raters was 1 mm; exact agreement was obtained in 72 subjects. Correlations between raters were high (r(p) 0.87-0.97 in boys and 0.82-0.96 for girls). Interrater reliability was excellent (Cronbach's alpha, 0.97-0.98). Standard assessment techniques for ulnar variance are reliable in the adolescent population. Open growth plates did not interfere with this assessment. Young adolescent boys demonstrated a greater degree of negative ulnar variance compared with young adolescent girls. Copyright © 2011 American Society for Surgery of the Hand.

Burnett Heyes, Stephanie; Jih, Yeou-Rong; Block, Per; Hiu, Chii-Fen; Holmes, Emily A; Lau, Jennifer Y F

2015-01-01

Adolescence is characterized as a period of social reorientation toward peer relationships, entailing the emergence of sophisticated social abilities. Two studies (Study 1: N = 42, ages 13-17; Study 2: N = 81, ages 13-16) investigated age group differences in the impact of relationship reciprocation within school-based social networks on an experimental measure of cooperation behavior. Results suggest development between mid- and late adolescence in the extent to which reciprocation of social ties predicted resource allocation. With increasing age group, investment decisions increasingly reflected the degree to which peers reciprocated feelings of friendship. This result may reflect social-cognitive development, which could facilitate the ability to navigate an increasingly complex social world in adolescence and promote positive and enduring relationships into adulthood. © 2015 The Authors.

The pharmacokinetics of abacavir and its metabolites were investigated in 30 human immunodeficiency virus (HIV)-infected adolescents and young adults 13-25 years of age, equally divided into two groups: <18 years of age and ≥18 years of age. All the subjects received the recommended adult dose of 300 mg twice daily. The area under the plasma concentration-time curve (AUC) and half-life of abacavir did not differ significantly between the age groups or by gender or race, and there were only modest associations of age with apparent abacavir clearance and with volume of distribution. There were no significant correlations of carboxylate or glucuronide metabolite levels with age or gender, although glucuronide AUC was higher in Hispanic subjects than in African-American subjects. Zidovudine and lamivudine concentration profiles were also similar in the two age groups. A novel aspect of the study included an assessment of intracellular carbovir, zidovudine, and lamivudine triphosphate levels, and these were found to be similar in the two age-based groups. Overall, these findings suggest that current recommendations relating to adult dosages are appropriate for adolescents and young adults. PMID:19118380

2017-03-01

The present study was a first look at the ontogenetic pattern of dream content across the lifespan for men. The participants included 50 Canadian men in each of 5 age groups, from adolescence to old age including 12-17, 18-24, 25-39, 40-64, and 65-85. The last age group included 31 participants, totaling 231 males. One dream per participant was scored by two independent judges using content analysis. Trend analysis was used to determine the lifespan-developmental pattern of the dream content categories. Results demonstrated a predominance of aggressive dream imagery in the adolescent age group in line with social-developmental research. These patterns of dream imagery reflect the waking developmental patterns as proposed by social theories and recognized features of aging. Limitations and suggestions for future research, including the examining of the developmental pattern of gender differences across the lifespan, are discussed. Copyright © 2017 Elsevier Inc.

Objective: To determine and compare rates of homotypic continuity of childhood- and adolescent-onset depression into adulthood. Method: This was a naturalistic, prospective cohort study of children and adolescents receiving psychiatric care at all community mental health centers in Madrid, Spain, from January 1986 to December 2007. Data were obtained from a regional registry wherein all psychiatric visits to public mental health centers are recorded. Patients received their first diagnosis of an ICD-10 F32 or F33 depressive disorder between 6 and 17 years of age and were at least 20 years old at the time of their last visit. Subjects whose first diagnosis was in childhood (aged 6–12 years: depressed-child group) and subjects whose first diagnosis was in adolescence (aged 13–17 years: depressed-adolescent group) were compared in terms of demographic characteristics, psychiatric comorbidity, and rates of homotypic continuity in adulthood. Results: Five hundred twenty-eight patients with depressive disorders met inclusion criteria. The depressed-adolescent group had a higher proportion of girls (60.3%) compared to the depressed-child group, but did not differ on other demographic or clinical variables. Most subjects who later received treatment in adult mental health facilities (n = 243; 57.2%; 95% CI, 50.9–57.2) continued to be diagnosed with a depressive disorder. High rates of anxiety disorders, bipolar disorder, personality disorders, and psychotic disorders in adulthood were observed among subjects from both groups. The absence of psychiatric comorbidity prior to age 18 years was associated with homotypic continuity of depressive disorder into adulthood. Conclusions: Subjects with adolescent-onset depression and subjects without comorbid psychiatric disorders in youth appear to have a higher level of homotypic continuity into adulthood. Both children and adolescents with depressive disorders are at risk for other psychiatric disorders in adulthood. PMID:22295270

The objective of this study was to establish potential risk factors for poor health-related quality of life among adolescents with epilepsy in Montenegro. A sample of 104 adolescents with epilepsy (age: 11-19years) at a tertiary referral center in Podgorica, Montenegro, completed the validated Serbian version of the QOLIE-AD-48 questionnaire. They were divided into two groups: a group with active epilepsy (60 adolescents) and a group with inactive epilepsy (44 adolescents). Demographic and clinical data were collected. Adolescents with active epilepsy had low quality of life and felt the negative impact of the disease. They also had more cognitive impairments, felt more stigmatized, and had considerably more distorted perception of their health than adolescents with inactive epilepsy (p<0.05). Females reported better social support than males (p<0.05). Older males had lower grades at school (p<0.05) than the younger ones. As expected, adolescents with the highest number of seizures in the past two years had the lowest quality of life (p<0.05). In our study, the quality of life in adolescents with epilepsy was determined by severity of the disease, age, and gender. Copyright © 2017 Elsevier Inc. All rights reserved.

Excessive TV viewing and cardiovascular disease risk factors in adolescents. The AVENA cross-sectional study

PubMed Central

2010-01-01

Background Excessive television (TV) viewing might play an important role in the development of cardiovascular disease (CVD). The aim of this study was to examine the independent associations between TV viewing and CVD risk factors in adolescents. Methods A sample of 425 adolescents, aged 13- to 18.5-year-old, was included in this study. Body mass index (BMI), waist circumference (WC), glucose, total cholesterol, triglycerides, HDL-cholesterol, LDL-cholesterol, apolipoprotein (apo) A-1, apo B-100, and lipoprotein(a) levels were determined. A composite CVD risk score was computed based on age-, sex-, sexual maturation- and race-standardized triglycerides, HDL-cholesterol, LDL-cholesterol and glucose. TV viewing was self-reported. Results Two hundred and twenty-five adolescents (53%) who spent >3 hrs/day watching TV were considered as the "high TV viewing" group. Ninety-nine adolescents (23%) from the total sample were classified as overweight according to International age- and sex-specific BMI values. The high TV viewing group had significantly less favorable values of HDL-cholesterol, glucose, apo A1 and CVD score, independent of age, sex, sexual maturation, race and weight status. There was a significant interaction effect of TV viewing × weight status (P = 0.002) on WC, and the negative influence of TV viewing on WC persisted in the overweight group (P = 0.031) but was attenuated in non-overweight adolescents (P > 0.05). Conclusion Excessive TV viewing seems to be related to an unfavorable CVD risk factors profile in adolescence. Reducing TV viewing in overweight adolescents might be beneficial to decrease abdominal body fat. PMID:20500845

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 contributes to slowing down the process of sexual maturation both with the development of andrological pathology in adolescents.

Internet addiction is one of the most common problems among adolescents and effective treatment is needed. This research aims to test the effectiveness and underlying mechanism of multi-family group therapy (MFGT) to reduce Internet addiction among adolescents. A total of 92 participants consisting of 46 adolescents with Internet addiction, aged 12-18years, and 46 their parents, aged 35-46years, were assigned to the experimental group (six-session MFGT intervention) or a waiting-list control. Structured questionnaires were administered at pre-intervention (T1), post-intervention (T2) and a three-month follow-up (T3). There was a significant difference in the decline both in the average score and proportion of adolescents with Internet addiction in MFGT group at post-intervention (MT1=3.40, MT2=2.46, p<0.001; 100 versus 4.8%, p<0.001) maintained for three months (MT3=2.06, p<0.001; 100 versus 11.1%, p<0.001). Reports from both adolescents and parents were significantly better than those in the control group. Further explorations of the underlying mechanisms of effectiveness based on the changed values of measured variables showed that the improvement in adolescent Internet use was partially explained by the satisfaction of their psychological needs and improved parent-adolescent communication and closeness. The six-session multi-family group therapy was effective in reducing Internet addiction behaviors among adolescents and could be implemented as part of routine primary care clinic services in similar populations. As family support system is critical in maintaining the intervention effect, fostering positive parent-adolescent interaction and addressing adolescents' psychological needs should be included in preventive programs for Internet addiction in the future.

Chronic prostatitis (CP)/chronic pelvic pain syndrome (CPPS) has been studied mainly in adults; reports in adolescents are rare. We compared the clinical characteristics of adolescent CP/CPPS patients with those of young adults. We retrospectively analyzed 20 adolescents with CP/CPPS aged <20 years who visited our outpatient department from August 2005 to April 2012. The control group comprised 120 young adult CP/CPPS patients. A complete medical history, physical examination, the national institute of health-chronic prostatitis symptoms index (NIH-CPSI) questionnaire, urinalysis, expressed prostatic secretion (EPS) or semen analysis, transrectal prostate ultrasonography, and prostate-specific antigen (PSA) were performed. Based on the EPS or semen analysis, patients were divided into category III-A or III-B. The mean age was 16.5±2.0 and 32.8±5.0 years in the adolescent and control groups, respectively. A sexual activity history was seen in 2 patients; 9 and 11 patients were in category III-A and III-B, respectively. The PSA was 0.65±0.39 and 1.22±0.48 ng/mL in the adolescent and control groups, respectively. The prostate size was 12.4±4.4 and 21.0±4.9 g in the adolescent and control groups, respectively. The NIH-CPSI scores in the adolescent group were 9.2±5.2, 5.5±3.5, 7.5±3.2, and 22.2±8.1 for pain, voiding, quality of life (QoL) domains, and total scores, respectively. The adolescent group showed a tendency to exhibit high voiding symptom scores. CPPS has an equally severe impact on QoL in adults and adolescents. Apart from high voiding symptom scores in adolescents, no difference was found in terms of urologic clinical parameters.

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

The purpose of this study was to improve upon the first version of the basic work skills assessment tool for adolescents with autism spectrum disorder (ASD) and examine interrater and intrarater reliability using Intraclass Correlation Coefficient (ICC). The modified tool includes 2 components: (1) three tasks measuring work abilities and work attitudes and (2) a form to record the number of verbal and nonverbal prompts. 26 participants were selected by purposive sampling and divided into 3 groups—group 1 (10 subjects, aged 11–13 years), group 2 (10, aged 14–16 years), and group 3 (6, aged 17–19 years). The results show that interrater reliabilities of work abilities and work attitudes were high in all groups except that the work attitude in group 1 was moderate. Intrarater reliabilities of work abilities in group 1 and group 2 were high. Group 3 was moderate. Intrarater reliabilities of work attitudes in group 1 and group 3 were high but not in group 2 in which they were moderate. Nevertheless, interrater and intrarater reliabilities in the total scores of all groups were high, which implies that this tool is applicable for adolescents aged 11–19 years with consideration of relevance for each group.

To investigate the effect of racism, own-group ethnic density, diversity and deprivation on adolescent trajectories in psychological well-being. Multilevel models were used in longitudinal analysis of psychological well-being (total difficulties score (TDS) from Goodman's Strengths and Difficulties Questionnaire, higher scores correspond to greater difficulties) for 4782 adolescents aged 11-16 years in 51 London (U.K.) schools. Individual level variables included ethnicity, racism, gender, age, migrant generation, socio-economic circumstances, family type and indicators of family interactions (shared activities, perceived parenting). Contextual variables were per cent eligible for free school-meals, neighbourhood deprivation, per cent own-group ethnic density, and ethnic diversity. Ethnic minorities were more likely to report racism than whites. Ethnic minority boys (except Indian boys) and Indian girls reported better psychological well-being throughout adolescence compared to their white peers. Notably, lowest mean TDS scores were observed for Nigerian/Ghanaian boys, among whom the reporting of racism increased with age. Adjusted for individual characteristics, psychological well-being improved with age across all ethnic groups. Racism was associated with poorer psychological well-being trajectories for all ethnic groups (p<0.001), reducing with age. For example, mean difference in TDS (95% confidence interval) between boys who experienced racism and those who did not at age 12 years=1.88 (+1.75 to +2.01); at 16 years = +1.19 (+1.07 to +1.31). Less racism was generally reported in schools and neighbourhoods with high than low own-group density. Own ethnic density and diversity were not consistently associated with TDS for any ethnic group. Living in more deprived neighbourhoods was associated with poorer psychological well-being for whites and black Caribbeans (p<0.05). Racism, but not ethnic density and deprivation in schools or neighbourhoods, was an important influence on psychological well-being. However, exposure to racism did not explain the advantage in psychological well-being of ethnic minority groups over whites.

To study the secular trend of menarche in high-school urban adolescent girls (Zagreb, Croatia) over the last two decades, and to evaluate the possible impact of worsening of socio-economic conditions on age at menarche during the Croatian War of Independence (1991-1995). Three surveys of female adolescents aged 15-19 years: (a) 523 girls interviewed in 1990, (b) 888 girls interviewed in 1997, and (c) 399 girls interviewed in 2010. Self-reported age at menarche (in decimal years) was presented by age groups and year of interview. Differences in mean age at menarche between adolescent age groups as well as between surveys were tested using One-way ANOVA. The mean age at menarche was 12.82 years in 1990, 12.92 years in 1997 and 12.31 years in 2010. It increased by 0.10 years from 1990 to 1997 (p=0.290) and then declined by 0.61 years from 1997 to 2010 (p<0.001). Over the 20-year period, the overall mean age at menarche declined by 0.51 years (p<0.001). The age at menarche in Zagreb adolescents continued to decline significantly from 1990 to 2010 (p<0.001), in spite of a statistically insignificant initial increase between 1990 and 1997. When put in broader context, age at menarche mirrored socio-economic changes in the war period. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

Today continuous subcutaneous insulin infusion (CSII) is frequently used in children and adolescents with type 1 diabetes mellitus. The present cross-sectional trial aimed to document current practice, quality of diabetes control and incidence of acute complications in different age-groups under CSII vs. multiple daily insulin injection therapy (MIT). Moreover the survey analyzed socio-demographic backgrounds of the patients. A total of 901 patients (age 11.5±4.0, diabetes duration 4.0±3.6 years) was entered in the database. Clinical data, laboratory parameters and, using a standardized questionnaire, socio-demographic data were assessed. For age-related analyses patients were allocated to 4 groups: pre-school children (< 6 years), pre-adolescents (≥ 6 and<11 years), adolescents (≥ 11 and<16 years) and young adults (≥ 16 and<22 years). Of the cohort n=194 had a CSII, n=707 had a MIT. Patients with CSII vs. MIT had a longer diabetes duration, they used more frequently insulin analogues, performed more frequently blood-glucose self-tests and had a lower insulin dosage per kilogram body weight. In respect of HbA1c, the mean amplitude of blood-glucose excursions, but also of lipids, creatinine, microalbuminuria and blood pressure, there were no differences in neither age-group between patients with CSII and MIT. In patients with CSII and MIT, there was a tendency (p<0.05) towards an increase in HbA1c in adolescents and young adults and there was a decrease (p<0.05 for tendency) in the frequency of hypoglycaemia from the age group of young adults to pre-school children. Adolescents and young adults with CSII had a higher educational level. Pre-adolescents, adolescents and young adults with CSII have also better diabetes-related knowledge. Moreover, in all age-groups, the parents of patients with CSII had mostly a lower unemployment rate and higher educational levels. The present analyses demonstrate that in all age-groups CSII provides convenient and flexible insulin delivery during routine treatment of type 1 diabetes. There is reasonable quality of diabetes control accompanied by a low incidence of hypoglycaemia and ketoacidosis. However, under CSII and MIT there is an increase of HbA1c towards adolescence. It must also highlighted that CSII seems to be expansive and that CSII is more frequently used in patients with better educational levels and deriving from higher social classes. © Georg Thieme Verlag KG Stuttgart · New York.

To analyse nutritional risk, by age and sex, among primary and secondary education adolescents from Cantabria. a cross-sectional study was carried out, analysing a sample of 1101 adolescents: 568 (51.6%) were men and 533 (48.4%) were women, aged 12 to 17, attending 16 different primary and secondary education centres in Cantabria, by means of a Krece Plus questionnaire. A high percentage of adolescents with a high nutritional risk (35%) can be observed. Men show a high nutritional risk slightly higher than women (37.8% male vs 32.1% female). Moreover, the high nutritional risk experiences a notable increase as young people get older. Significant statistical differences can be seen both in male and female groups, and as a global group. In all three cases, the nutritional risk distribution in the youngest group is very similar (35.2-35.8% in male, 27.9-29.7% in female, 31.7-32.7% in the global group); whereas in elder adolescents, those values are practically doubled (57.1% in male, 69.0% in female, y 62.2% in the global group). Results are alarming mainly given the high percentage of adolescents with a high nutritional risk. Men and older adolescents are the groups in which high nutritional risk is more evident.

Research consistently identifies a group of adolescents who refrain from minor delinquency entirely. Known as abstainers, studying these adolescents is an underexplored approach to understanding adolescent minor delinquency. In this paper, we tested hypotheses regarding adolescent delinquency abstention derived from the developmental taxonomy model and social control theory in 497 adolescents (283 boys) aged 13-18 comparing three groups of adolescents: abstainers, experimenters, and a delinquent group. We found that the relation between adolescent abstention and personal characteristics (i.e., conscientiousness and anxiety) was (partially) mediated by the amount of time spent with peers. Furthermore, the level of best friend delinquency moderated the relation between time spent with peers and delinquency abstention. Results support aspects of both theoretical frameworks. © 2016 The Authors. Journal of Research on Adolescence © 2016 Society for Research on Adolescence.

2017-08-01

Weapon-related violent crime is a serious, complex, and multifaceted public health problem. The present study uses data from Waves I and III of Add Health (n = 10,482, 54% female) to examine how friendship group integration and cohesion in adolescence (ages 12-19) is associated with weapon-related criminal activity as a young adult (ages 18-26). Results indicate that greater cohesion in friendship groups is associated with significantly lower weapon-related criminal activity in young adulthood. In addition, for adolescent girls, a greater number of close friendship ties-an indicator of friendship group integration-is associated with less weapon-related criminal activity in young adulthood. These findings suggest that school-based initiatives to facilitate inclusive and cohesive adolescent peer communities may be an effective strategy to curb weapon-related criminal activity in young adulthood.

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.

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

Background/Objectives: To assess the intake of fluid in healthy French children, adolescents, adults and seniors, considering amounts, types of beverages, time and place of consumption. Subjects/Methods: Data regarding fluid intake were extracted and analyzed from the National Intake Survey, which was conducted in quota samples of the French population (Comportement et Consommations Alimentaires en France study). Seven-day questionnaires were administered to free-living individuals in 2002–2003. A total of 566 children (aged 6–11 years), 333 adolescents (aged 12–19 years), 831 adults (aged 20–54 years) and 443 seniors (aged ⩾55 years) were included in this study. Results: The average total intake of fluid was 1–1.3 l per day depending on age groups. Water accounted for about one-half of daily fluid intake. The contribution of other types of beverages varied with age (for example, dairy drinks in children and adolescents; alcoholic drinks in adults and seniors). Intake of sodas (including regular and light) was highest in adolescents (169 ml a day). Beverages were mainly consumed at home during meals. Conclusions: This is the first description of fluid intake in French children, adolescents, adults and seniors, considering amounts, types of beverages, time and place of intake. It shows that water is the main source of fluid in all age groups. Selection of various types of beverages is different according to age. PMID:20160751

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

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

Effects of the social environment during adolescence on the development of social behaviour, hormones and morphology in male zebra finches (Taeniopygia guttata).

PubMed

Bölting, Stefanie; von Engelhardt, Nikolaus

2017-01-01

Individual differences in behaviour are widespread in the animal kingdom and often influenced by the size or composition of the social group during early development. In many vertebrates the effects of social interactions early in life on adult behaviour are mediated by changes in maturation and physiology. Specifically, increases in androgens and glucocorticoids in response to social stimulation seem to play a prominent role in shaping behaviour during development. In addition to the prenatal and early postnatal phase, adolescence has more recently been identified as an important period during which adult behaviour and physiology are shaped by the social environment, which so far has been studied mostly in mammals. We raised zebra finches ( Taeniopygia guttata ) under three environmental conditions differing in social complexity during adolescence - juvenile pairs, juvenile groups, and mixed-age groups - and studied males' behavioural, endocrine, and morphological maturation, and later their adult behaviour. As expected, group-housed males exhibited higher frequencies of social interactions. Group housing also enhanced song during adolescence, plumage development, and the frequency and intensity of adult courtship and aggression. Some traits, however, were affected more in juvenile groups and others in mixed-age groups. Furthermore, a testosterone peak during late adolescence was suppressed in groups with adults. In contrast, corticosterone concentrations did not differ between rearing environments. Unexpectedly, adult courtship in a test situation was lowest in pair-reared males and aggression depended upon the treatment of the opponent with highest rates shown by group-reared males towards pair-reared males. This contrasts with previous findings, possibly due to differences in photoperiod and the acoustic environment. Our results support the idea that effects of the adolescent social environment on adult behaviour in vertebrates are mediated by changes in social interactions affecting behavioural and morphological maturation. We found no evidence that long-lasting differences in behaviour reflect testosterone or corticosterone levels during adolescence, although differences between juvenile and mixed-age groups suggest that testosterone and song behaviour during late adolescence may be associated.

The aim of the study was to assess the relationships between perceived parenting style, depressed mood, anxiety and self-esteem in adolescents with heart disease compared with healthy adolescents. Forty-five adolescents, aged 12-18 with congenital or acquired heart disease and 50 healthy age-matched adolescents answered perceived parental behaviour, self-esteem, depressed mood and anxiety questionnaires. The study group reported higher perceived acceptance and lower perceived parental control than healthy adolescents, but similar levels of depressed mood, anxiety and self-esteem. Fischer's r-to-z transformation and regression analyses showed different associations between perceived parenting style and depressed mood, anxiety and self esteem. In the study group, higher perceived parental acceptance was associated with lower depressed mood and higher self-esteem, whereas these associations were not significant in the control group. In the control, but not the study group, higher perceived parental control was associated with lower depressed mood and lower anxiety. Parenting style proved to exert a differential effect on adolescents with and without heart disease. For the former, perceived parental acceptance had a more substantial effect on psychological well-being than perceived parental control. Professionals caring for these adolescents should be aware of the special importance of parenting style on the well-being of adolescents with heart disease, and address this issue in the clinical setting with the patients and their parents.

Background/Objective: The objective of the study was to provide current estimates of the prevalence and trends of overweight and obesity (OW+OB) in Mexican children and adolescents. Subjects/Methods: Body mass index objectively measured was analyzed for 37 147 children and adolescents aged 0–19 years obtained in 2012 as part of the National Health and Nutrition Survey (ENSANUT-2012), a nationally representative sample of the Mexican population. In addition, data from previous National Nutrition Surveys obtained in 1988, 1999 and 2006 were compared with analyze trends over a 24-year period (1988–2012) for children <5 years of age and adolescents and over a 13-year period (1999–2012) for school-age children. World Health Organization Child Growth Standard was used to define OW+OB. Results: In 2012, 33.5% of children <5 years of age (both sexes) were at risk of overweight or were overweight (OW); 32% and 36.9% of girls and boys 5–11 years of age were OW+OB, respectively, and 35.8% and 34.1% of female and male adolescents were OW+OB, respectively. Statistically significant trends were documented for all age groups during the study period. Overall change in the combined prevalence in preschool children was 6.3±1.0 percentage points (pp; P<0.001; 0.26 pp per year) in the last 24 years, showing the highest increase between 1988 and 1999, whereas for school-age girls (from 1999 to 2012) and adolescent females (from 1988 to 2012), OW+OB increased across all periods at a declining trend, with an overall change of 0.5 and 1.0 pp per year, respectively. Changes in the prevalence of OW+OB were highest among children and adolescents in the lowest quintile of the household living condition index. Conclusions: Prevalence of OW+OB among children and adolescents increased significantly during the last 13–24 years. The rate of increase has declined in the last 6 years in all age groups. Changes in prevalence of OW+OB presented here suggest that, in Mexico, the burden of obesity is shifting toward the groups with lower socioeconomic level. PMID:28287630

Joint trajectories of depression and perfectionism across adolescence and childhood risk factors.

The codevelopment of symptoms of depression and socially prescribed perfectionism across adolescence (age 12-17) and non-age-overlapping childhood predictors (age 10-11) of joint trajectory group membership were examined in a sample of 700 Canadian youth. Results indicated that most adolescents (75.8%) followed a trajectory of low depression symptoms (low stable), whereas 15.7% followed an increasing trajectory (increasing), and 8.5% followed a trajectory that began high and decreased over time (high decreasing). More girls than boys were found in the increasing and high decreasing depression trajectories. Adolescents followed three distinct trajectories of socially prescribed perfectionism: 41.6% were in a low stable group, 40.5% in a moderate increasing group, and 17.9% in a high increasing group. Eight percent followed a high-risk dual trajectory of increasing depression and high increasing socially prescribed perfectionism. This joint trajectory was predicted by being bullied, anxious, and relationally aggressive (compared to the low-risk trajectory of low stable depression and perfectionism) at ages 10 and 11. These same predictors, along with poorer family functioning and lower family income, differentiated the joint high decreasing depression/high increasing perfectionism group from the low/low joint group, which comprised of 3.8% of the sample. The developmental progression was best characterized as depression leading to socially prescribed perfectionism. Implications for clinical practice are discussed.

The purpose of this study was to investigate the role of age, gender, peer, family, and culture in adolescent risky sexual behavior for Cambodian and Laotian (Lao)/Mien youth. We obtained cross-sectional, in-home interview data including measures of individualism, collectivism, acculturation, risky sexual behavior, peer delinquency, parent engagement, and parent discipline from a sample of mostly second-generation Cambodian (n = 112) and Lao/Mien (n = 67) adolescents. Data were analyzed using step-wise, hierarchical multiple regressions. Peer delinquency and age (older) were significant predictors of risky sexual behavior in both groups. Parent discipline also significantly predicted risky sexual behavior, but only for Lao/Mien adolescents. Vertical and horizontal individualism were associated positively with risky sexual behavior for Cambodian youth whereas collectivism (horizontal) was associated negatively with risky sexual behavior for Lao/Mien youth. Acculturation was nonsignificant in both groups. In addition to age, parents, and peer groups, the findings suggest that culture also matters in risky sexual behavior, particularly for Cambodian and Laotian youth.

Neurocognitive performance in children and adolescents with bipolar disorder: a review.

A number of studies have reported the evidence of cognitive deficits in adult bipolar patients. Recently, there has been a shift in research on neurocognitive performance in bipolar disorder (BD) towards examining younger age groups. A review of the literature on neurocognitive impairments in BD in childhood and adolescence was conducted. We searched systematically for studies in samples of age groups younger than 18 years of age in average that included either a healthy control group or normative data for the cognitive tests used. Twenty-one original articles were found and reviewed. Children and adolescents with BD show deficits in a variety of cognitive areas. The most consistent results were found for impairments in verbal memory. A majority of studies also indicated impairments in working memory. Similar pattern of neurocognitive impairment was found in children and adolescents as compared to adults suffering from BD. The neurocognitive deficits need to be recognized and incorporated into individual treatment programs.

Age trajectories for personality traits are known to be similar across cultures. To address whether stereotypes of age groups reflect these age-related changes in personality, we asked participants in 26 countries (N = 3,323) to rate typical adolescents, adults, and old persons in their own country. Raters across nations tended to share similar beliefs about different age groups; adolescents were seen as impulsive, rebellious, undisciplined, preferring excitement and novelty, whereas old people were consistently considered lower on impulsivity, activity, antagonism, and Openness. These consensual age group stereotypes correlated strongly with published age differences on the five major dimensions of personality and most of 30 specific traits, using as criteria of accuracy both self-reports and observer ratings, different survey methodologies, and data from up to 50 nations. However, personal stereotypes were considerably less accurate, and consensual stereotypes tended to exaggerate differences across age groups. PMID:23088227

In this study, our objective is to assess the perception of family environments by adolescents with ADHD based on perceived expressed emotion (EE) and the self-esteem of the adolescents. Uludag University Medical Faculty Hospital completed this study with 41 adolescents with ADHD and 35 control group participants who were matched based on age and gender. The total scores of perceived EE, described as a lack of emotional support, irritability, and intrusiveness, were significantly higher in ADHD group than in the control group. The group with ADHD also showed significantly lower self-esteem. There was a negative correlation between self-esteem scores and total perceived EE scores in the ADHD group and the control group. This study showed that the adolescents with ADHD perceive less emotional support and higher levels of intrusiveness, with patients also describing their families as more irritating. Other results in this study show that adolescents with less emotional support possess lower self-esteem, as do adolescents with more irritable parents.

It has been suggested that fluoride in drinking water may increase the risk of osteosarcoma in children and adolescents, although the evidence is inconclusive. We investigated the association between community water fluoridation (CWF) and osteosarcoma in childhood and adolescence in the continental U.S. We used the cumulative osteosarcoma incidence rate data from the CDC Wonder database for 1999-2006, categorized by age group, sex and states. States were categorized as low (≤30%) or high (≥85%) according to the percentage of the population receiving CWF between 1992 and 2006. Confidence intervals for the incidence rates were calculated using the Gamma distribution and the incidence rates were compared between groups using Poisson regression models. We found no sex-specific statistical differences in the national incidence rates in the younger groups (5-9, 10-14), although 15-19 males were at higher risk to osteosarcoma than females in the same age group (p<0.001). Sex and age group specific incidence rates were similar in both CWF state categories. The higher incidence rates among 15-19 year old males vs females was not associated with the state fluoridation status. We also compared sex and age specific osteosarcoma incidence rates cumulated from 1973 to 2007 from the SEER 9 Cancer Registries for single age groups from 5 to 19. There were no statistical differences between sexes for 5-14 year old children although incidence rates for single age groups for 15-19 year old males were significantly higher than for females. Our ecological analysis suggests that the water fluoridation status in the continental U.S. has no influence on osteosarcoma incidence rates during childhood and adolescence.

Dextromethorphan hydrobromide (DM) is a widely used antitussive. This study determined, for the first time, the basic pharmacokinetic profile of DM and its active metabolite, dextrorphan (DP) in children and adolescents. Thirty-eight male and female subjects at risk for developing an upper respiratory tract infection (URTI), or symptomatic with cough due to URTI, were enrolled in this single-dose, open-label study: ages 2-5 years (Group A, n = 8), 6-11 years (Group B, n = 17), 12-17 years (Group C, n = 13). Subjects were genotyped for cytochrome P450 (CYP) 2D6 polymorphisms and characterized as poor (PM) or non-poor metabolizers (non-PM). Groups A and B were dosed using an age-weight dosing schedule (DM range 7.5-24.75 mg); a 30-mg dose was used for Group C. Average exposures to total DP increased as age group increased, and average exposure to DM was highest in the adolescent group. One subject in that group was a PM. The terminal half-life (t ½) values were longer in the adolescent group due in part to the single PM subject. No relationship between body weight and pharmacokinetic parameters was noted. This is the first evaluation of the pharmacokinetic characteristics of DM in children and adolescents. A single dose of DM in this population was safe, and well tolerated at all doses tested. The data are used to model and compare pediatric DM exposures with those of adults.

Prediction of peer-rated adult hostility from autonomy struggles in adolescent–family interactions

2006-01-01

Observed parent–adolescent autonomy struggles were assessed as potential predictors of the development of peer-rated hostility over a decade later in young adulthood in both normal and previously psychiatrically hospitalized groups of adolescents. Longitudinal, multireporter data were obtained by coding family interactions involving 83 adolescents and their parents at age 16 years and then obtaining ratings by close friends of adolescents’ hostility at age 25 years. Fathers’ behavior undermining adolescents’ autonomy in interactions at age 16 years were predictive of adolescents-as-young-adults’ hostility, as rated by close friends at age 25 years. These predictions contributed additional variance to understanding young adult hostility even after accounting for concurrent levels of adolescent hostility at age 16 years and paternal hostility at this age, each of which also significantly contributed to predicting future hostility. Results are discussed as highlighting a pathway by which difficulties attaining autonomy in adolescence may presage the development of long-term difficulties in social functioning. PMID:11893089

Much research has examined Moffitt's developmental taxonomy, focusing almost exclusively on the distinction between life-course persistent and adolescence-limited offenders. Of interest, a handful of studies have identified a group of individuals whose early childhood years were marked by extensive antisocial behavior but who seemed to recover and desist (at least from severe offending) in adolescence and early adulthood. We use data from the Cambridge Study in Delinquent Development to examine the adult adjustment outcomes of different groups of offenders, including a recoveries group, in late middle adulthood, offering the most comprehensive investigation of this particular group to date. Findings indicate that abstainers comprise the largest group of males followed by adolescence-limited offenders, recoveries, and life-course persistent offenders. Furthermore, the results reveal that a host of adult adjustment problems measured at ages 32 and 48 in a number of life-course domains are differentially distributed across these four offender groups. In addition, the recoveries and life-course persistent offenders often show the greatest number of adult adjustment problems relative to the adolescence-limited offenders and abstainers.

A critical social theory approach to nursing care of adolescents with diabetes.

PubMed

Dickinson, J K

1999-01-01

This paper explores the viewpoint that, as a group, adolescents with diabetes are oppressed by health care professionals who use approaches to diabetes care delivery that are paternalistic in nature. These approaches can lead to negative health/diabetes outcomes in this age group. As inherent in oppressed group characteristics, adolescents with diabetes may not realize that they are being treated unfairly or that they have rights as patients. Nurses are in a unique position to advocate for these adolescents and to help them become advocates for themselves.

Context While young racial/ethnic groups are the fastest growing population in the United States, data on alcohol and drug use disorders among adolescents of various racial/ethnic backgrounds are lacking. Objective To examine the magnitude of past-year Diagnostic and Statistical Manual of Mental Disorders-IV substance use disorders (alcohol, marijuana, cocaine, inhalants, hallucinogens, heroin, analgesic opioids, stimulants, sedatives, tranquilizers) among whites, Hispanics, African Americans, Native Americans, Asians/Pacific Islanders, and multiple-race adolescents. Design 2005–2008 National Surveys of Drug Use and Health. Setting Non institutionalized, household adolescents aged 12–17 years. Main Measures Substance use disorders were assessed by standardized survey questions administered by the audio computer-assisted self-interviewing method. Results Of all adolescents aged 12–17 (N=72,561), 37% used alcohol or drugs in the past year; 8% met criteria for an alcohol or drug use disorder, with Native Americans having the highest prevalence of use (48%) and disorder (15%). Analgesic opioids were the second most commonly used illegal drugs in all racial/ethnic groups, following marijuana; opioid use was comparatively prevalent among Native Americans (10%) and multiple-race adolescents (9%). Among past-year alcohol or drug users (n=27,705), Native Americans (32%), multiple-race adolescents (25%), whites (23%), and Hispanics (21%) had the highest rates of alcohol or drug use disorders. Marijuana was used by adolescents more frequently than alcohol or other drugs, and 26% of marijuana users met criteria for marijuana abuse/dependence. Controlling for adolescents’ age, socioeconomic variables, population density of residence, self-rated health, and survey year, adjusted analyses of adolescent substance users indicated elevated odds of having alcohol and drug use disorders among Native Americans, multiple-race adolescents, whites, and Hispanics compared with African Americans; the latter group did not differ from Asians/Pacific Islanders. Conclusions Substance use is widespread among Native-American, multiple-race, white, and Hispanic adolescents. These groups also are disproportionately affected by alcohol and drug use disorders.

There is evidence that cue-induced sucrose seeking progressively increases after cessation of oral sucrose self-administration (incubation of sucrose craving) in both adolescent and adult rats. The synaptic plasticity changes associated with this incubation at different age groups are unknown. We assessed whether incubation of sucrose craving in rats trained to self-administer sucrose as young adolescents, adolescents, or adults is associated with changes in 2-amino-3-(3-hydroxy-5-methyl-isoxazol-4-yl)propanoic acid (AMPA)/N-methyl-D-aspartate (NMDA) ratio (a measure of postsynaptic changes in synaptic strength) in nucleus accumbens. Three age groups initiated oral sucrose self-administration training (10 days) on postnatal day (P) 35 (young adolescents), P42 (adolescents), or P70 (adults). They were then tested for cue-induced sucrose seeking (assessed in an extinction test) on abstinence days 1 and 21. Separate groups of rats were trained to self-administer sucrose or water (a control condition), and assessed for AMPA/NMDA ratio in nucleus accumbens on abstinence days 1-3 and 21. Adult rats earned more sucrose rewards, but sucrose intake per body weight was higher in young adolescent rats. Time-dependent increases in cue-induced sucrose seeking (incubation of sucrose craving) were more pronounced in adult rats, less pronounced in adolescents, and not detected in young adolescents. On abstinence day 21, but not days 1-3, AMPA/NMDA ratio in nucleus accumbens were decreased in rats that self-administered sucrose as adults and adolescents, but not young adolescents. Our data demonstrate age-dependent changes in magnitude of incubation of sucrose craving and nucleus accumbens synaptic plasticity after cessation of sucrose self-administration.

2014-07-01

Narrative and trait levels of personality were assessed in a sample of 268 adolescents from age 12 to 21 from New Zealand Māori, Chinese, and European cultures. Adolescents narrated three critical events and completed a Big Five personality inventory. Each narrative was coded for causal and thematic coherence. NZ Chinese adolescents reported lower levels of extraversion, agreeableness, conscientiousness, and openness, and higher levels of neuroticism, than NZ Māori or European adolescents. Cultural differences were also evident in narrative coherence. Adolescents in all three groups demonstrated age-related increases in thematic coherence, but only NZ European adolescents demonstrated the expected age-related increases in causal coherence. Narrative identity and traits were distinct aspects of personality for younger adolescents, but were linked for middle and older adolescents. These findings support the importance of both narrative identity and traits in understanding personality development in adolescents across cultures.

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

Little is known about the type and severity of sleep disturbances in the pediatric chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) population, compared with healthy adolescents. Using a range of objective and subjective measures, the aim of this study was to investigate sleep quality, the relationship between objective and subjective measures of sleep quality, and their associations with anxiety in adolescents with CFS/ME compared with healthy controls. Twenty-one adolescents with CFS/ME aged 13 to 18 years (mean age 15.57 ± 1.40), and 145 healthy adolescents aged 13 to 18 years (mean age 16.2 ± 1.00) wore actigraphy watches continuously for 2 weeks to collect a number of objective sleep variables. The Pittsburgh Sleep Quality Index was used to obtain a subjective measure of sleep quality. Anxiety was measured by the Spence Children's Anxiety scale. On average over the 2-week period, adolescents with CFS/ME were found to have (1) significantly longer objective sleep onset latency, time in bed, total sleep time, and a later rise time (all P < .005), and (2) significantly poorer subjective sleep quality ( P < .001), compared with healthy adolescents. The CFS/ME patient group displayed higher levels of anxiety ( P < .05), and in both groups, higher levels of anxiety were significantly related to poorer subjective sleep quality ( P < .001). This study provides objective and subjective evidence of sleep disturbance in adolescents with CFS/ME compared with healthy adolescent controls. © 2017 American Academy of Sleep Medicine

2015-01-01

Purpose Polycystic ovary syndrome (PCOS) is characterized by hyperandrogenic anovulation in women of reproductive age. We investigated the metabolic effects of lean and overweight adolescents with PCOS. Methods Anthropometric measurements and biochemical parameters were evaluated in 49 adolescents with PCOS and 40 age- and body mass index (BMI)-matched controls. We further divided both PCOS and control groups into those having BMI within the normal range of less than 85th percentile and those being overweight and obese with a BMI greater than 85th percentile. Results Hemoglobin, gamma-glutamyl transferase (r-GT), total cholesterol, low-density lipoprotein-cholesterol and 2-hour postglucose load plasma insulin levels were significantly elevated in the lean PCOS group than in the lean control group. In the overweight/obese PCOS group, hemoglobin and r-GT levels were significantly elevated than in the overweight/obese control group. In the normal weight group, none of the subjects had metabolic syndrome according to the Adult Treatment Panel III criteria, but the incidence of metabolic syndrome in the overweight/obese PCOS group was 8.3% and that in the overweight/obese control group was 6.7%. Conclusion PCOS in adolescents causes metabolic abnormalities, underscoring the importance of early diagnosis of PCOS in oligomenorrheic adolescents. PMID:26512349

Alcohol is the most consumed substance among young people, and the onset of its use is starting at an earlier age, raising the risks of future dependence. The use of alcohol in adolescence is associated with a series of risk behaviors, besides raising the risk of involvement in accidents, sexual violence, and participating in gangs. Alcohol use by adolescents is strongly associated with violent death, poor academic performance, learning difficulties and damage in the development and structuring of cognitive-behavioral and emotional abilities. Alcohol consumption causes neurochemical modifications, with damage in memory, learning and impulse control. Professionals who deal with adolescents must be prepared for a thorough evaluation regarding the possible abusive use or dependence of alcohol in this age group. However, it is important to emphasize that the criteria utilized by some diagnostic tools for abuse and dependence were developed for adults, and must be applied with caution in adolescents. Thus, it is fundamental that these professionals be aware of the characteristics and peculiarities of adolescence and chemical dependence in this age-group.

A randomized controlled trial to investigate the impact of a low glycemic index (GI) diet on body mass index in obese adolescents

PubMed Central

2014-01-01

Background The role of a low glycemic index (GI) diet in the management of adolescent obesity remains controversial. In this study, we aim to evaluate the impact of low GI diet versus a conventional Chinese diet on the body mass index (BMI) and other obesity indices of obese adolescents. Methods Obese adolescents aged 15–18 years were identified from population-recruited, territory-wide surveys. Obesity was defined as BMI ≥95th percentile of Hong Kong local age- and sex-specific references. Eligible subjects were randomized to either an intervention with low GI diet (consisting of 45-50% carbohydrate, 30-35% fat and 15-20% protein) or conventional Chinese diet as control (consisting of 55-60% carbohydrate, 25-30% fat and 10-15% protein). We used random intercept mixed effects model to compare the differential changes across the time points from baseline to month 6 between the 2 groups. Results 104 obese adolescents were recruited (52 in low GI group and 52 in control group; 43.3% boys). Mean age was 16.7 ± 1.0 years and 16.8 ±1.0 years in low GI and control group respectively. 58.7% subjects completed the study at 6 months (65.4% in low GI group and 51.9% in control group). After adjustment for age and sex, subjects in the low GI group had a significantly greater reduction in obesity indices including BMI, body weight and waist circumference (WC) compared to subjects in the control group (all p <0.05). After further adjustment for physical activity levels, WC was found to be significantly lower in the low GI group compared to the conventional group (p = 0.018). Conclusion Low GI diet in the context of a comprehensive lifestyle modification program may be an alternative to conventional diet in the management of obese adolescents.

Using a Life Course Health Development framework, this article summarizes what is known about the impact of cancer and its treatment on the biopsychosocial world of the adolescent and young adult. Published peer reviewed literature, web-based resources, and cancer-related professional organizations' resources. Adolescents and young adults with cancer, between 15 and 29 years of age, have emerged as a distinct group requiring specialized care. The demands of cancer and its treatment are often directly counter to the developmental needs of this age group and often alter those life course experiences that contribute to resilience, thriving, and flourishing. Providing high-quality care to this age group requires a depth of understanding of the complexity of factors that merge to influence the developmental life course. Copyright © 2015 Elsevier Inc.

The implications of having attention-deficit/hyperactivity disorder in male adolescents with intellectual disability.

PubMed

Carmeli, Eli; Klein, Neomy; Sohn, Mordechai

2007-01-01

Attention-deficit/hyperactivity disorder (ADHD) is currently defined as a cognitive/behavioral developmental disorder where all clinical criteria are behavioral. The purpose of this study was to demonstrate a correlation between social skills and ADHD among adolescents with intellectual disabilities (ID). The study concerns the specific cognitive and adaptive skills of adolescents dually diagnosed with mild intellectual disabilities and comorbid pathology as ADHD. Three age-and IQ-match groups (males, n = 12 in each group) were investigated. Group I--composed of adolescent diagnosed with mild ID, group II--adolescents diagnosed with ADHD, and group III--adolescents diagnosed with ID and ADHD. The instruments used in the study were Wechsler Intelligence Scale for Children (WISC, according to the chronological age of the subjects) and the short version of the Developmental Behavior Checklist (DBC). Results confirm that comorbidity is a factor differentiating. ADHD strongly increased the impairment of social skills, while behavioral disorders were less damaging in ID performance. The WISC and DBC instruments should be used with confidence in clinical and service settings, to allow a better assessment of co-occurrence morbidity in adolescents with ID. The interactions between intellectual disability and psychopathology behavior highlight the need to plan a more accurate diagnosis and appropriate rehabilitative intervention program, essential for improving the quality of life of the ID population.

Relation between adolescent idiopathic scoliosis and morphologic somatotypes.

1997-11-01

A prospective and controlled comparative study. To verify the difference in morphologic appearance between a group of adolescents with progressive adolescent idiopathic scoliosis and a control group of normal adolescents. In a previous retrospective study, the possibility of a relation between progressive adolescent idiopathic scoliosis and specific morphotypes was demonstrated. Fifty-two adolescent girls with progressive adolescent idiopathic scoliosis were compared with an age-matched control group of 62 unaffected girls using a classification technique based on morphologic somatotypes. Morphotypes were evaluated with standardized pre-established criteria based on Sheldon's technique. Patients with progressive adolescent idiopathic scoliosis showed significantly less mesomorphism (mean value of 0.88 +/- 0.51) than control girls (mean value of 1.72 +/- 0.52). Adolescent girls with progressive adolescent idiopathic scoliosis have a morphologic somatotype that is different from the normal adolescent population. Subjects with progressive adolescent idiopathic scoliosis are significantly less mesomorphic than control girls. This observation may be of value as a predictive factor for early identification of subjects with adolescent idiopathic scoliosis at greater risk of progression.

Assess perceptions of parental monitoring and sexual communication for sexual health promotion among adolescents who are Mexican. Adolescents (N=153, n=85 females, n=68 males) between 14years (n=80) and 15 years (n=73) were recruited at a public high school in Monterrey in the state of Nuevo Leon, Mexico. All participants were living with a parent(s). Descriptive statistical analyses were conducted to assess sociodemographic characteristics of the group. Chi-square analyses were conducted to identify potential group differences among the adolescents by age, gender and sexual activity regarding responses to each item of the Spanish Version Parental Monitoring and Sexual Communication Scale (a=0.88). Eleven percent of adolescents self-reported sexual activity. Significant group differences by age, gender and sexual activity were identified concerning parental monitoring and sexual communication including: less parental monitoring with older age (14 versus 15 year olds); more parental monitoring for females than males; less monitoring for sexually active adolescents; greater sexual communication for males than females, and among adolescents who were sexually active. An assessment of adolescents' perceptions of parental monitoring and sexual communication is useful for development of strategies concerning sexual health promotion in Mexico. The Spanish Version Parental Monitoring and Sexual Communication Scale can be used for assessment and modification of interventions for adolescent populations in Mexico. Information obtained from this assessment can be used to assist parents to enhance positive outcomes for parental monitoring and sexual communication with their children.

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

Venetsanou, Fotini; Kambas, Antonis

2017-05-01

This study investigated if motor proficiency (MP) in preschool age associate with physical activity (PA) in adolescence. In 2004, the Bruininks-Oseretsky Test of Motor Proficiency-Short Form (BOTMP-SF) (7) was administered to 413 children, aged 4-6 years, who were classified to MP groups according to their BOTMP-SF total score (TS). In 2014, the PA of 106 former participants (47 boys, 59 girls) was measured with Omron pedometers. MP [three (high; above average; average)] × gender (two) ANOVA and Bonferroni tests were computed on average of steps/week. A significant interaction between the two factors was revealed (F = 15.27, p < .001, η 2 =.153), indicating that MP influenced male and female PA differently. Only in average MP group, males presented higher PA than females, whereas there were no differences between the two genders in the higher MP groups. Moreover, the only significant difference in PA among male groups was that between high and above average MP groups, while in females there were significant differences among all groups. High MP at preschool age positively associated with the PA in adolescence, especially in females. Emphasis on the development of proficient young movers might be beneficial for lifelong PA.

This study aimed to measure quality of life (QOL) of the primary family caregivers for patients with Prader-Willi syndrome (PWS). Comparisons were made between caregivers' QOL in regard to their dependents' genotype and age group. The participants with PWS consisted of 22 children (aged from 6 to 12 years) and 23 adolescents (aged from 13 to 19 years), including 6 children and 7 adolescents with maternal uniparental disomy (mUPD) and 16 children and 16 adolescents with deletion (DEL). The QOL of the primary family caregiver for each patient was assessed using the Japanese version of the WHOQOL-BREF. To examine the effect that age (children vs. adolescents) and genotype (DEL vs. mUPD) have on the QOL of caregivers, a two-way ANOVA was conducted, followed by the Bonferroni procedure to test the simple main effects. The two age groups and the two genotypes of PWS were used as independent variables and the total QOL of caregivers as a dependent variable. The two-way ANOVA (F(1, 41) = 6.98, P < 0.05), followed by the Bonferroni procedure, showed the following: the total QOL of caregivers of DEL adolescents showed little difference from that with DEL children, but the QOL of caregivers for mUPD adolescents was shown to be lower than that with mUPD children along with that of caregivers with DEL adolescents. There is hence a growing tendency for the deterioration in the QOL of caregivers to manifest itself later in the patients' adolescence, found mainly with mUPD patients. © 2014 The Authors.

Cell population data (CPD) describe physical parameters of white blood cell subpopulations and are reported to be of some value in the diagnosis of sepsis in neonates. Before using the CPD for diagnosing sepsis, the baseline features of the CPD distribution in healthy neonates should be clarified. The aim of this study was to compare the CPD distributions of healthy neonates and other age groups and to identify perinatal factors that are associated with changes in the CPD distribution of healthy neonates. The CPD distribution of 69 samples from term neonates was compared with adolescents and adults. The CPD distribution of 163 samples from healthy neonates was analyzed in association with perinatal factors, including gestational age, chronologic age, birthweight, delivery mode, premature rupture of membranes, diabetes, and pregnancy-induced hypertension. The CPD distribution for term neonates was significantly different from those in adolescents and adults. The mean lymphocyte volume showed a negative correlation with gestational age at birth (r = -0.305; P < 0.01). The mean neutrophil volume was smaller in the cesarean section group than in the normal delivery group. The small for gestational age (SGA) group had smaller mean neutrophil volume and mean monocyte volume than the appropriate for gestational age group. The CPD distribution of healthy neonates differed from those of adolescents or adults, and the differences were associated with gestational age, delivery mode, and being SGA. © 2015 John Wiley & Sons Ltd.

This study explored factors associated with the mental health in adolescents (ages 11-17; n = 54) within 12 months after a parent had been diagnosed with cancer. A control group was included (ages 11-17; n = 49). A demographic questionnaire, the SF-8 Health Survey, the Youth Self Report and the McMaster Family Assessment Device were used. Similar levels of psychological distress and healthy family functioning were reported in the clinical and the control group. No effect of gender of the ill parent and that of the adolescent was found. A negative correlation was found between the physical health of the ill parent and the mental health of the adolescent. Healthy family functioning correlated with less psychological distress in adolescents with a parent with cancer. Open communication, flexible problem solving and appropriate affective involvement were significant predictors for less psychological distress in the adolescents. The study concludes that a healthy family functioning facilitated the adolescent's adjustment to parental cancer.

To investigate whether reported fast-food consumption over the previous year is associated with higher childhood or adolescent body mass index (BMI). Secondary analysis from a multicentre, multicountry cross-sectional study (International Study of Asthma and Allergies in Children (ISAAC) Phase Three). Parents/guardians of children aged 6-7 completed questionnaires which included questions about their children's asthma and allergies, fast-food consumption, height and weight. Adolescents aged 13-14 completed the same questionnaire. The questionnaire asked "In the past 12 months, how often on average did you (your child) eat fast-food/burgers?" The responses were infrequent (never/only occasionally), frequent (once/twice a week) or very frequent (three or more times per week). A general linear mixed model was used to determine the association between BMI and fast-food consumption, adjusting for Gross National Income per capita by country, measurement type (whether heights/weights were reported or measured), age and sex. 72,900 children (17 countries) and 199,135 adolescents (36 countries) provided data. Frequent and very frequent fast-food consumption was reported in 23% and 4% of children, and 39% and 13% of adolescents, respectively. Children in the frequent and very frequent groups had a BMI that was 0.15 and 0.22 kg/m(2) higher than those in the infrequent group (p<0.001). Male adolescents in the frequent and very frequent groups had a BMI that was 0.14 and 0.28 kg/m(2) lower than those in the infrequent group (p<0.001). Female adolescents in the frequent and very frequent groups had a BMI that was 0.19 kg/m(2) lower than those in the infrequent group (p<0.001). Reported fast-food consumption is high in childhood and increases in adolescence. Compared with infrequent fast-food consumption, frequent and very frequent consumption is associated with a higher BMI in children. Owing to residual confounding, reverse causation and likely misreporting, the reverse association observed in adolescents should be interpreted with caution.

The gynecologic issues of adolescents with disabilities are understudied. The purpose of this study was to identify and compare the presenting complaints, treatments, and follow-up of adolescent girls with Down syndrome (DS), autism, and cerebral palsy (CP) presenting to a specialized gynecologic clinic for women with developmental disabilities. Outpatient gynecology clinic. Forty four adolescents (<21 y); 13 with DS, 14 with autism, and 17 with CP who presented to the clinic from 1999 to 2006. None. A retrospective review of the electronic medical records to collect data on age at presentation to clinic, ethnicity, menstrual history, chief complaint, treatment, and follow-up. Mean age at presentation to clinic was 15+/-3.5 years, and age of menarche was 12.5+/-2 years; age at menarche did not significantly differ between groups. The most frequent complaints were irregular bleeding (n=10) and mood/behavioral changes (n=6). Girls with autism were significantly (chi(2)=8.89, P=.012) more likely to present with behavioral issues than the other 2 groups. Initial management for the behavior issues in the autism group included nonsteroidal anti-inflammatory drugs (NSAID), oral contraceptives, and education. The most common gynecologic complaints of adolescent girls with DS, autism, and CP centered on menstruation and mood disorders. Patients with autism were more likely to present with behavioral issues related to the onset of periods. Copyright 2010 North American Society for Pediatric and Adolescent Gynecology.

To investigate the impact of maternal age on pregnancy outcomes with special emphasis on adolescents and older mothers and to investigate the differences in demographic profile between adolescents and older mothers. This study is a secondary analysis of pregnancy outcomes of women in Riyadh Mother and Baby cohort study according to maternal age. The study population was grouped according to maternal age into five subgroups; <20, 20-29, 30-34, 35-39 and 40+years. The age group 20-29 years was considered as a reference group. Investigation of maternal age impact on maternal and neonatal outcomes was conducted with adjustment of confounders using regression models. All mothers were married when conceived with the index pregnancy. Young mothers were less likely to be illiterate, more likely to achieve higher education and be employed compared with mothers ≥ 40 years. Compared with the reference group, adolescents were more likely to have vaginal delivery (and least likely to deliver by caesarean section (CS); OR=0.6, 95% CI 0.4 to 0.9, while women ≥40 years, were more likely to deliver by CS; OR 2.9, 95% CI 2.3 to 3.7. Maternal age was a risk factor for gestational diabetes in women ≥40 years; OR 1.7, 95% CI 1.3 to 2.1. Adolescents had increased risk of preterm delivery; OR 1.5, 95% CI 1.1 to 2.1 and women ≥40 years had similar risk; OR, 1.3, 95% CI 1.1 to 1.6. Adverse pregnancy outcomes show a continuum with the advancement of maternal age. Adolescents mother are more likely to have vaginal delivery; however, they are at increased risk of preterm delivery. Advanced maternal age is associated with increased risk of preterm delivery, gestational diabetes and CS. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

2014-07-01

The goal of this study was to identify heterogenic longitudinal patterns of change in prosocial behavior from adolescence to early adulthood and their association with change in Big Five Factor (BFF) personality traits from adolescence until early adulthood. Participants were 573 Italian adolescents aged approximately 13 at the first assessment and 21 at the last assessment. Using growth mixture modeling, low increasing (LI; 18%), medium quadratic (MQ; 26%), and high quadratic (HQ; 54%) trajectories of prosocial behavior were distinguished. Generally, the LI trajectory group predicted an increase in Conscientiousness over time, whereas the HQ trajectory group predicted greater change in Agreeableness and Openness. In addition, positive changes in Conscientiousness, Agreeableness, and Openness between ages 13 and 21 predicted a higher probability of belonging to the HQ prosocial group. Findings support a malleable perspective on personality and identify longterm positive pathways for youths' prosocial development.

Shaw, T; Campbell, M A; Runions, K C; Zubrick, S R

2017-07-01

Although developed for adults, the Depression Anxiety Stress Scales-Short Version (DASS-21) has been used in many research studies with adolescent samples. Evidence as to the applicability of the DASS subscale scores to represent the distinct states of depression, anxiety, and stress as experienced by adolescents is mixed, and the age at which it may be possible to differentiate these 3 states using the DASS-21 has not yet been determined. This study evaluated evidence for a multifactor structure in the DASS-21 in adolescents and the specificity of the 3 subscales for adolescents in general and at different ages. Data were from a large cross-sectional survey of 2,873 school students in Grades 6-12 (aged 12-18 years) in Australia. We conducted confirmatory bifactor analyses testing a general mental health distress factor and 3 domain-specific factors for anxiety, depression, and stress for the whole sample and across gender by age groups. The internal consistency reliability of the DASS total and subscale scores was determined using omega coefficients. Analyses identified that most of the variation in the items was explained by the dominance of a single, general factor and the subscales lacked specificity across all age groups. The DASS-21 can be reliably used to measure general distress in adolescents, but the subscales fail to discriminate between the 3 states. Our results indicate that this lack of discrimination does not reduce with increasing age. These findings caution against the use of adult theoretical models and measures within adolescent populations. © 2016 Wiley Periodicals, Inc.

Encouraging adolescents to adopt healthy lifestyles can be challenging. The aim of the "Som la Pera" study was to engage adolescents by applying new strategies to increase both their fruit and vegetable consumption and their physical activity (PA) while reducing their sedentary behavior. In disadvantaged neighborhoods of Reus (Spain), two high schools were randomly assigned to the intervention (n = 170 adolescents 13- to 16-year-olds) and two were assigned to the control group (n = 223 adolescents 13- to 16-year-olds). The intervention, which lasted 12 months and spanned 2 academic years (2013-2015), used social marketing (SM) to improve healthy choices. The peer-led strategy involved 5 adolescents who designed and implemented 10 activities as challenges for their 165 school-aged peers. The control group received no intervention. To assess self-reported lifestyles in both groups, the Health Behavior in School-Aged Children Survey was used at baseline and end of study. After 12 months, intervention adolescents showed an increase of 28.9% in ≥1 fruit/day (p < 0.01) and of 18.5% in ≥6 hours/week of PA (p < 0.01) compared with controls. Additionally, intervention group males had an increase of 28.8% in ≥1 vegetable/day (p < 0.01) and of 15.6% in ≤2 hours/day of sedentary activity (p = 0.01) compared with controls. A school-based, peer-led, SM intervention developed by adolescents attending high schools in low-income neighborhoods effectively improved the healthy choices of their school-aged peers, leading to increased fruit consumption and PA in adolescents of both genders. Furthermore, adolescent males were more sensitive to improvements in healthy choices, showing increased vegetable consumption and decreased sedentary behavior.

To investigate age-related differences in polysomnographic and sleep electroencephalographic (EEG) measures, considering sex, pubertal stage, ethnicity, and scalp topography in a large group of adolescents in the National Consortium on Alcohol and NeuroDevelopment in Adolescence (NCANDA). Following an adaptation/clinical screening night, 141 healthy adolescents (12-21 y, 64 girls) had polysomnographic recordings, from which sleep staging and EEG measures were derived. The setting was the SRI International Human Sleep Laboratory and University of Pittsburgh Pediatric Sleep Laboratory. Older age was associated with a lower percentage of N3 sleep, accompanied by higher percentages of N2, N1, and rapid eye movement (REM) sleep. Older boys compared with younger boys had more frequent awakenings and wakefulness after sleep onset, effects that were absent in girls. Delta (0.3-4 Hz) EEG power in nonrapid eye movement NREM sleep was lower in older than younger adolescents at all electrode sites, with steeper slopes of decline over the occipital scalp. EEG power in higher frequency bands was also lower in older adolescents than younger adolescents, with equal effects across electrodes. Percent delta power in the first NREM period was similar across age. African Americans had lower EEG power across frequency bands (delta to sigma) compared with Caucasians. Finally, replacing age with pubertal status in the models showed similar relationships. Substantial differences in sleep architecture and EEG were evident across adolescence in this large group, with sex modifying some relationships. Establishment and follow-up of this cohort allows the investigation of sleep EEG-brain structural relationships and the effect of behaviors, such as alcohol and substance use, on sleep EEG maturation. © 2016 Associated Professional Sleep Societies, LLC.

Internet addiction has emerged as a major public health problem worldwide. In November 2011, the South Korean government implemented an online game shutdown policy, lasting from 12:00 to 6:00 am, as a means of preventing Internet addiction in adolescents aged 15 or below. This study analyzed the effect of this shutdown policy on adolescent Internet use, addiction, and sleeping hours. We analyzed data collected from the Korea Youth Risk Behavior Web-based Survey from 2011 to 2015. Respondents were divided into two groups by age: aged 15 or below (male = 76,048, female = 66,281) and aged 16 or above (male = 52,568, female = 49,060). A difference-in-difference analysis was used to evaluate the effect of this shutdown policy. In 2012, which is immediately following policy enforcement, daily amount of Internet use (in minutes) decreased more in adolescents affected by the policy (i.e., the aged 15 or below group). However, it steadily increased in 2013, 2014, 2015, and showed no meaningful long-term improvements 4 years after policy implementation (-3.648 minutes in 2012 [p = .001], -3.204 minutes in 2013 [p = .011], -1.140 minutes in 2014 [p = .384], and 2.190 minutes in 2015 [p = .107]). The shutdown policy did not alter Internet addiction or sleeping hours. Interestingly, female adolescents, adolescents with low academic performance, and adolescents with low exercise levels exhibited comparatively stronger and longer lasting initial declines in Internet usage. The shutdown policy had practically insignificant effects in reducing Internet use for target adolescents. Thus, policymakers aiming to reduce or prevent Internet addiction should use different strategies. Copyright © 2017 The Society for Adolescent Health and Medicine. Published by Elsevier Inc.

Aim: The evaluation of the effect of repeat cesarean sections in adolescent pregnancies on the morbidity, obstetric and perinatal results. Materials and methods: We reviewed the patient file and hospital records of patients who underwent at least one cesarean section among adolescent age group pregnant women who gave birth at our clinic between January 2010 and May 2013. The patients were divided into two groups as the patients who underwent the second cesarean section (116 patients) and those who underwent the third cesarean section (36 patients). The demographic data, maternal data and obstetric and perinatal results of the patients were evaluated. Results: A significant difference was present between the patients in the evaluation of the total number of examinations during pregnancy (P = 0.001), total maternal weight gain during pregnancy (P = 0.006), and the first examination gestational age (P = 0.006) and all values were less favorable in the third cesarean group. The gestational week at birth (P < 0.001), birth weight (P < 0.001), and APGAR score (P < 0.001) in the group with the third cesarean section were statistically significantly lower than the second cesarean section. The third cesarean cesarean was found to cause a significant risk increase for placenta accreta risk in adolescent pregnancies (P = 0.042). Conclusion: The increasing number of cesarean sections in the adolescent group is seen to be a significant risk factor for low gestational week of birth, low birth weight and related morbidities. The most important reason for the increased morbidity with increasing cesarean sections in the adolescent age has been defined as placenta accreta. PMID:25664081

The changing face of bipolar disorder: adolescence to adulthood.

Over the past decade, there has been greater acceptance of the existence of bipolar disorder (BD) in adolescents. The onset of BD during this period severely affects the acquisition of key developmental skills. Debate around diagnosis, comorbidity and treatment is strong and little is known about the long-term impact BD has on an adolescents as they approach adulthood, from both illness and functional perspectives. A review of psychological and medical databases using the search terms ''adolescent onset'', ''pediatric onset'', ''juvenile onset'', ''bipolar disorder'', ''course'' and ''outcome'' was conducted. Emphasis was placed on the information available from studies, which have described the outcome of adolescent onset BD either prospectively, retrospectively, or both. Twelve studies were identified that focused on the long-term course of adolescent onset BD. Findings on the course and outcomes are conflicting. These studies are from few centres or research groups and have small sample sizes, varied methodologies and relatively brief follow-up durations. There are few studies available on the course and outcome of adolescent onset BD. Although there seems to be less controversy in this age group compared to the prepubertal age group, there remains a need for prospective studies of large systematically ascertained samples.

Sociocultural characteristics of pregnant and nonpregnant adolescents of low socioeconomic status: a comparative study.

The objective of this study was to compare the sociocultural characteristics of pregnant adolescents of low SES with a nonpregnant adolescent group from the same area of Santiago, Chile. The sample was composed of 229 adolescents, 129 of whom were pregnant for the first time (group A), and 100 who were not pregnant (group B). Each pregnant girl was matched with a nonpregnant girl of the same age and from the same neighborhood. Several differences between the groups were found. Group A had less schooling, a lower level of aspirations, and tended to live in "the present." In addition, norms of behavior were more permissive, they did not practice any religion, and their peer group had more liberal attitudes. The importance of breaking these patterns in order to prevent adolescent pregnancy is discussed.

Developmental Effects of Incentives on Response Inhibition

Geier, Charles F.; Luna, Beatriz

2012-01-01

Inhibitory control and incentive processes underlie decision-making, yet few studies have explicitly examined their interaction across development. Here, the effects of potential rewards and losses on inhibitory control in sixty-four adolescents (13-17-year-olds) and forty-two young adults (18-29-year-olds) were examined using an incentivized antisaccade task. Notably, measures were implemented to minimize age-related differences in reward valuation and potentially confounding motivation effects. Incentives affected antisaccade metrics differently across the age groups. Younger adolescents generated more errors than adults on reward trials, but all groups performed well on loss trials. Adolescent saccade latencies also differed from adults across the range of reward trials. Overall, results suggest persistent immaturities in the integration of reward and inhibitory control processes across adolescence. PMID:22540668

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

Moral judgment and conduct disorder intensity in adolescents involved in delinquency: matching controls by school grade.

PubMed

Chudzik, Lionel

2007-08-01

Most studies that have found associations between delinquency and moral judgment generally compare incarcerated juveniles with adolescents in normal schooling. However, this comparison is subject to two criticisms. First, a large number of adolescents in school who are not charged with any crime in the legal system are still involved in unlawful behaviour. Second, adolescents involved with delinquency often have difficulties at school. The aim of the present study was to measure this association by matching a sample of adolescents involved with delinquency (n=18, M age=15.8, SD=1.1) to adolescents not involved in delinquency (n=42, M age=15.8, SD=0.8) according to their school grade and Conduct Disorder Intensity as measured by a self-report index using DSM-IV diagnostic criteria. Participants who met four or more criteria were assigned to the High Conduct Disorder group (n=28), and the rest were assigned to the Low Conduct Disorder group (n=32). Their level of moral judgment was evaluated with the French version of the Sociomoral Reflection Measure-Short Form by Gibbs, Basinger, and Fuller, inspired by Kohlberg's model of moral development. Findings demonstrate that in both samples, adolescents in the High Conduct Disorder group presented moral judgment that was significantly less mature than that of adolescents in the Low Conduct Disorder group. However, the majority of participants in the Low Conduct Disorder group also scored low on the Sociomoral Reflection Measure-Short Form, suggesting more immature moral judgment. The bias introduced by the mode of recruitment in most comparisons of adolescents involved with delinquency to adolescents with no delinquency problems is discussed, and an argument is made for the importance of analysing moral judgment development within a framework of general cognitive development.

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

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

Obesity: locus of control, body image, weight loss, and age-at-onset.

PubMed

Wineman, N M

1980-01-01

In a retrospective investigation designed to measure locus of control, body image, and weight loss in Overeaters Anonymous members who had childhood, adolescence, or adulthood onset of obesity, 116 subjects were grouped according to age at onset of obesity and the year they joined OA. A convenience, volunteer sample of OA members completed a demographic data questionnaire, Rotter's Social Reaction. Inventory, and Secord and Jourard's Body Cathexis Scale. Significant overweight percentage differences were not found when the three age-at-onset groups were compared. Significant differences emerged, however, for adolescent-onset group persons who were categorized as "old" members; they had a larger weight loss and were more satisfied with their body image. A positive linear relationship between greater perception of internal control and a good body image was found in the entire adulthood-onset group. Weight loss and good body image of the oldest adolescent-onset group probably was the outcome of their association with a self-help group i.e., OA. Assessment of developmental issues related to the time of initial weight gain may indicate which treatment regime would be most effective.

Music therapy to promote prosocial behaviors in aggressive adolescent boys--a pilot study.

Rickson, Daphne J; Watkins, William G

2003-01-01

This pilot study was undertaken to investigate whether music therapy is effective in promoting prosocial behaviors in aggressive adolescent boys who have social, emotional, and learning difficulties. Fifteen subjects (aged 11-15 years), enrolled at a special residential school in New Zealand, were randomly assigned to music therapy treatment groups (n = 6, n = 5), and a waitlist control group (n = 4). Examination of demographic data identified differences between groups for diagnosis (p =.044), with Group 1 all having Attention Deficit Hyperactivity Disorder (ADHD), and for age (p =.027), with Group 2 having a mean age 1.38 years older. Measures included parent and teacher versions of the Developmental Behaviour Checklist (DBC-P & DBC-T) (Einfeld & Tonge, 1994; Einfeld, Tonge, & Parmenter, 1998). While no definite treatment effects could be detected, results suggest that a music therapy program promoting autonomy and creativity may help adolescents to interact more appropriately with others in a residential villa setting, but might also lead to a temporary mild increase in disruptive behavior in the classroom. A more highly structured program and smaller group numbers may be advantageous for boys who have ADHD.

The role of incretins in type 2 diabetes is controversial. This study investigated the association between incretin levels in obese Korean children and adolescents newly diagnosed with type 2 diabetes. We performed a 2-hr oral glucose tolerance test (OGTT) in obese children and adolescents with type 2 diabetes and with normal glucose tolerance. Twelve obese children and adolescents with newly diagnosed type 2 diabetes (DM group) and 12 obese age-matched subjects without type 2 diabetes (NDM group) were included. An OGTT was conducted and insulin, C-peptide, glucagon, glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) were measured during the OGTT. The mean age of the patients was 13·8 ± 2·0 years, and the mean body mass index (BMI) Z-score was 2·1 ± 0·5. The groups were comparable in age, sex, BMI Z-score and waist:hip ratio. The DM group had significantly lower homeostasis model assessment of β and insulinogenic index values (P < 0·001). The homeostasis model assessment of insulin resistance index was not different between the two groups. Insulin and C-peptide secretions were significantly lower in the DM group than in the NDM group (P < 0·001). Total GLP-1 secretion was significantly higher in the DM group while intact GLP-1 and GIP secretion values were not significantly different between the two groups. Impaired insulin secretion might be important in the pathogenesis of type 2 diabetes in obese Korean children and adolescents, however, which may not be attributed to incretin secretion. © 2015 John Wiley & Sons Ltd.

To determine the risk factors of adolescent pregnancies and to ascertain the effects of this condition on the maternal and infant outcomes. The study was carried out on 100 adolescent mothers less than 20 years of age and on a same number of adult mothers between 22 and 32 years of age and their infants. A socio-demographic attributes questionnaire form, a pregnancy follow-up and birth history form, and a mother and infant follow-up form were used. The mean age of the adolescent mothers was 17.8 ± 0.7 years and that of the adult mothers was 26 ± 0.3 years. Income level of 83% of the families of adolescent mothers and 69% of the families of adult mothers was below the poverty line (p < 0.05). Dropout rate (i.e. rate of those not attending any school) was 36% in the adolescent group and 21% in the adult group. Rate of exclusively breastfeeding during the first 2 months was 40% in adolescents and 62% in adults (p < 0.01). Higher rates of adolescent mothers felt themselves inadequate infant care and with 7% of them experiencing problems in accessing a healthcare institution. Properly following up adolescent pregnancies during prenatal and postnatal periods may be helpful for preventing the negative impacts on mother and infant health.

Read, DB, Jones, B, Phibbs, PJ, Roe, GAB, Darrall-Jones, J, Weakley, JJS, and Till, K. Physical demands of representative match-play in adolescent rugby union. J Strength Cond Res 31(5): 1290-1296, 2017-The purpose of this study was to quantify the physical demands of representative adolescent rugby union match-play and investigate the difference between playing positions and age groups. Players (n = 112) were classified into 6 groups by playing position (forwards and backs) and age group (U16, U18, and U20). The physical demands were measured using microsensor-based technology and analyzed using magnitude-based inferences to assess practical importance. Backs had a greater relative distance (except U16s) and a greater high-speed running distance per minute than forwards, with the magnitude of difference between the positions becoming larger in older age groups. Forwards had higher values of PlayerLoad (PL) per minute (accumulated accelerations from the 3 axes of movement) and PL slow per minute (accumulated accelerations from the 3 axes of movement where velocity is <2 m·s) than backs at all age groups. Relative distance, low-, and high-speed running per minute all had a trend to be lower in older age groups for both positions. PlayerLoad per minute was greater in U18 than that in U16 and U20 for both positions. PlayerLoad slow per minute was greater for older age groups besides the U18 and U20 comparisons, which were unclear. The contrasts in physical demands experienced by different positions reinforce the need for greater exposure to sprinting and collision-based activity for backs and forwards, respectively. Given PL metrics peak at U18 and locomotor demands seem to be lower in older ages, the demands of representative adolescent rugby union do not seem to be greater at U20 as expected.

2010-03-01

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

We examine changes to health insurance coverage and access to health care among children, adolescents, and young adults since the implementation of the Affordable Care Act. Using the National Health Interview Survey, bivariate and logistic regression analyses were conducted to compare coverage and access among children, young adolescents, older adolescents, and young adults between 2010 and 2016. We show significant improvements in coverage among children, adolescents, and young adults since 2010. We also find some gains in access during this time, particularly reductions in delayed care due to cost. While we observe few age-group differences in overall trends in coverage and access, our analysis reveals an age-gradient pattern, with incrementally worse coverage and access rates for young adolescents, older adolescents, and young adults. Prior analyses often group adolescents with younger children, masking important distinctions. Future reforms should consider the increased coverage and access risks of adolescents and young adults, recognizing that approximately 40% are low income, over a third live in the South, where many states have not expanded Medicaid, and over 15% have compromised health.

Updated and regional data about the circumstances of death and the psychosocial backgrounds of suicides can be helpful for improving suicide-preventive strategies in childhood and adolescence. All known cases of completed suicide in the period from 1996 to 2008 in persons ≤ 21 years of age from the Institute of Forensic Medicine, Frankfurt/Main were analysed in a retrospective study. We included 78 cases and matched them with a comparative sample of 1,797 adult suicides of persons > 21 years of age. Within the chosen period there was a 44 % decrease in incidence of suicide in the group of ≤ 21-year-olds. The fraction of incarcerated persons in this group was 8.0 % compared to 2.56 % in the adult group. Differences from suicide in adulthood were also demonstrated in terms of suicide-related substance abuse (less detection of alcohol, more frequent detection of illicit drugs) and choice of methods (more deaths by being hit by a train). Incarcerated adolescents are an important risk group for suicidal tendency and need increased, well-directed preventive measures. Clinical adolescent psychiatry should pay special attention to the indications in this study of an age-dependent association of drug use in suicide.

Objective. To investigate the effect of racism, own-group ethnic density, diversity and deprivation on adolescent trajectories in psychological well-being. Design. Multilevel models were used in longitudinal analysis of psychological well-being (total difficulties score (TDS) from Goodman's Strengths and Difficulties Questionnaire, higher scores correspond to greater difficulties) for 4782 adolescents aged 11–16 years in 51 London (UK) schools. Individual level variables included ethnicity, racism, gender, age, migrant generation, socioeconomic circumstances, family type and indicators of family interactions (shared activities, perceived parenting). Contextual variables were per cent eligible for free school-meals, neighbourhood deprivation, per cent own-group ethnic density, and ethnic diversity. Results. Ethnic minorities were more likely to report racism than Whites. Ethnic minority boys (except Indian boys) and Indian girls reported better psychological well-being throughout adolescence compared to their White peers. Notably, lowest mean TDS scores were observed for Nigerian/Ghanaian boys, among whom the reporting of racism increased with age. Adjusted for individual characteristics, psychological well-being improved with age across all ethnic groups. Racism was associated with poorer psychological well-being trajectories for all ethnic groups (p <0.001), reducing with age. For example, mean difference in TDS (95% confidence interval) between boys who experienced racism and those who did not at age 12 years = 1.88 (+1.75 to + 2.01); at 16 years = +1.19 (+1.07 to +1.31). Less racism was generally reported in schools and neighbourhoods with high than low own-group density. Own ethnic density and diversity were not consistently associated with TDS for any ethnic group. Living in more deprived neighbourhoods was associated with poorer psychological well-being for Whites and Black Caribbeans (p <0.05). Conclusion. Racism, but not ethnic density and deprivation in schools or neighbourhoods, was an important influence on psychological well-being. However, exposure to racism did not explain the advantage in psychological well-being of ethnic minority groups over Whites. PMID:22332834

The present study was aimed to find out the prevalence of overweight and obesity and its associated factors among Bengalee children and adolescents in the Kolkata, India. A total of 1061 Bengalee school children and adolescents (610 boys and 451 girls) participated and were divided into three age groups: Group I = 8-11 years; Group II = 12-15 years and Group III = 16-18 years. Overweight and obesity were defined as: Overweight (between ≥85 th and <95 th percentile) and obesity (≥95 th percentile). Multivariate regression analyses (adjusted for age and sex) of body mass index (BMI) revealed that about 18% (R2 = 0.185) of total variance of BMI could be explained by monthly family income, participants think obese, consumption of too much junk foodstuffs, breakfast skip, extra consumption of salt, and computer hours. Sedentary lifestyles, including increasing fast food preferences may be responsible for increasing occurrence of pediatric and adolescent obesity in this population.

This study investigated the relative contribution of syntactic awareness to Chinese reading among Chinese-speaking adolescent readers with and without dyslexia. A total of 78 junior high school students in Hong Kong, 26 dyslexic adolescent readers, 26 average adolescent readers of the same age (chronological age control group) and 26 younger readers matched with the same reading level (reading-level group) participated and were administered measures of IQ, syntactic awareness, morphological awareness, vocabulary knowledge, working memory, word reading, and reading comprehension. Results showed that dyslexic readers scored significantly lower than chronological age but similarly to reading level control groups in most measures, especially in the areas of syntactic skills. Analyses of individual data also revealed that over half of the dyslexic readers exhibited certain aspects of deficits in syntactic skills. In regression analyses, syntactic skills were the strongest predictors of ability in word reading and reading comprehension measures. This study highlights the uniquely important correlates of syntactic skills in Chinese reading acquisition and impairment. Copyright © 2013 John Wiley & Sons, Ltd.

This study investigated developmental differences in aversive conditioning, extinction, and reinstatement (i.e., the recovery of conditioned aversive associations following reexposure to the unconditioned stimulus [US] post-extinction). This study examined these mechanisms in children (M age =8.8years), adolescents (M age =16.1years), and adults (M age =32.3years) using differential aversive conditioning with a geometric shape conditional stimulus (CS+) paired with an aversive sound US and another shape (CS-) presented alone. Following an extinction phase in which both CSs were presented alone, half of the participants in each age group received three US exposures (reinstatement condition) and the other half did not (control condition), followed by all participants completing an extinction retest phase on the same day. Findings indicated (a) significant differences in generalizing aversive expectancies to safe stimuli during conditioning and extinction that persisted during retest in children relative to adults and adolescents, (b) significantly less positive CS reevaluations during extinction that persisted during retest in adolescents relative to adults and children, and (c) reinstatement of US expectancies to the CS+ relative to the CS- in all age groups. Results suggest important differences in stimulus safety learning in children and stimulus valence reevaluation in adolescents relative to adults. Copyright © 2017 Elsevier Inc. All rights reserved.

Purpose The aim of the study is to investigate how adolescents' perception of parents' and peers' smoking approval influences adolescent smoking intention, and how age affects this influence in a Swiss sample of adolescents. To know the influence of age can help to develop specific prevention programs tailored to the age groups needs. Method in a cross sectional survey, students aged between 11 and 14 from public and private middle schools in the Italian region of Switzerland (Ticino) answered questions on smoking habits, parents' and peers' approval and intention to smoke. Results peers' and parents' approval significantly influence students' smoking intention, and students' age significantly moderates this relation: the effect of parents' approval decreases for older adolescents, while the effect of peers' approval increases with age. No difference is found between girls and boys, while non-Swiss are more likely to smoke than Swiss students. Conclusions as literature suggests, results evidence the role parents play during early adolescence. Prevention programs targeting parent-child communication in early adolescence for preventing children's tobacco consumption are strongly supported. PMID:24991921

Body dysmorphic disorder (BDD) typically starts in adolescence, but evidence-based treatments are yet to be developed and formally evaluated in this age group. We designed an age-appropriate cognitive-behavioral therapy (CBT) protocol for adolescents with BDD and evaluated its acceptability and efficacy in a pilot randomized controlled trial. Thirty adolescents aged 12 to 18 years (mean = 16.0, SD = 1.7) with a primary diagnosis of BDD, together with their families, were randomly assigned to 14 sessions of CBT delivered over 4 months or a control condition of equivalent duration, consisting of written psycho-education materials and weekly telephone monitoring. Blinded evaluators assessed participants at baseline, midtreatment, posttreatment, and at 2-month follow-up. The primary outcome measure was the Yale-Brown Obsessive-Compulsive Scale Modified for BDD, Adolescent Version (mean baseline score = 37.13, SD = 4.98, range = 24-43). The CBT group showed a significantly greater improvement than the control group, both at posttreatment (time × group interaction coefficient [95% CI] = -11.26 [-17.22 to -5.31]; p = .000) and at 2-month follow-up (time × group interaction coefficient [95% CI] = -9.62 [-15.74 to -3.51]; p = .002). Six participants (40%) in the CBT group and 1 participant (6.7%) in the control condition were classified as responders at both time points (χ(2) = 4.658, p = .031). Improvements were also seen on secondary measures, including insight, depression, and quality of life at posttreatment. Both patients and their families deemed the treatment as highly acceptable. Developmentally tailored CBT is a promising intervention for young people with BDD, although there is significant room for improvement. Further clinical trials incorporating lessons learned in this pilot study and comparing CBT and pharmacological therapies, as well as their combination, are warranted.

Rationale Neuropsychological testing is widespread in adult cocaine abusers, but lacking in teens. Animal models may provide insight into age-related neuropsychological consequences of cocaine exposure. Objectives Determine whether developmental plasticity protects or hinders behavioral flexibility after cocaine exposure in adolescent vs. adult rats. Methods Using a yoked-triad design, one rat controlled cocaine delivery and the other two passively received cocaine or saline. Rats controlling cocaine delivery (1.0 mg/kg) self-administered for 18 sessions (starting P37 or P77), followed by 18 drug-free days. Rats next were tested in a strategy set shifting task, lasting 11–13 sessions. Results Cocaine self-administration did not differ between age groups. During initial set formation, adolescent-onset groups required more trials to reach criterion and made more errors than adult-onset groups. During the set shift phase, rats with adult-onset cocaine self-administration experience had higher proportions of correct trials and fewer perseverative + regressive errors than age-matched yoked-controls or rats with adolescent-onset cocaine self-administration experience. During reversal learning, rats with adult-onset cocaine experience (self-administered or passive) required fewer trials to reach criterion and the self-administering rats made fewer perseverative + regressive errors than yoked-saline rats. Rats receiving adolescent-onset yoked-cocaine had more trial omissions and longer lever press reaction times than age-matched rats self-administering cocaine or receiving yoked-saline. Conclusions Prior cocaine self-administration may impair memory to reduce proactive interference during set shifting and reversal learning in adult-onset but not adolescent-onset rats (developmental plasticity protective). Passive cocaine may disrupt aspects of executive function in adolescent-onset but not adult-onset rats (developmental plasticity hinders). PMID:24800898

Identification with social groups is associated with mental health in adolescents: Evidence from a Scottish community sample.

Miller, Kirsty; Wakefield, Juliet R H; Sani, Fabio

2015-08-30

The promotion and maintenance of mental health is an increasingly important societal issue. Previous research has shown that identification with social groups is positively associated with adult mental wellbeing, with multiple group identifications being particularly beneficial. The aim of the current study was to investigate whether the same is true for adolescents. 1111 Scottish secondary school students aged 13-17 completed a questionnaire investigating mental health symptoms and the extent of their identification with their family, school, and friendship groups. Higher identification with each group predicted better mental health. There was also an additive effect of group identification, with the odds of reporting psychiatric disturbance decreasing for every additional group with which participants identified strongly. These effects held even when age, gender, and group contact were controlled for. Our findings have implications for the prevention and treatment of mental problems, offering an alternative to traditional ways of viewing mental illness in adolescence and beyond.

Adolescents' reactions to hypothetical peer group conversations: evidence for an imaginary audience?

PubMed

Vartanian, L R

2001-01-01

The theory of adolescent egocentrism holds that early adolescents have a distorted understanding of self-other relations; because of flaws in the traditional methods used to assess adolescent egocentrism, this notion has never received adequate empirical scrutiny. In the present research, the nature of early adolescent social cognition as characterized by that theory was investigated by examining age differences in judgments of hypothetical peer group conversations. In Study 1, children and early adolescents (N = 264) rated the attentiveness, criticalness, and admiration expressed in three conversations, in which the subject or a peer was mentioned in either an admiring, critical, or nonevaluative manner. In Study 2, a similar procedure was used with middle and late adolescents, as well as children and early adolescents (N = 187); two memory tasks were also administered to visit the issue of distortion in social cognition. In Study 3, a new sample (N = 1,019) representing the four age groups from Study 2 was presented with an ambiguous conversation and then asked to interpret who was the target (object of focus) and how that target was regarded. The findings from the three studies do not support the notion that adolescents believe others are attentive to and critical of their every move, or that their social cognition and perception is egocentric and distorted. Conceptual and methodological contributions are discussed, along with directions for additional research.

More adolescents report pain now than previously. In Norway, episodic pain problems have been reported by 60% of children and adolescents aged 8-18 years, with 21% reporting duration of pain of more than 3 months. Since adolescents spend much time at school, the attitude and behaviour of teachers play important roles regarding the experience of pain felt by adolescents in everyday life. Yet research on how teachers perceive the pain experienced by adolescents in a school setting is limited. We therefore seek to gain insight to teachers' classroom experiences with (1) adolescent's self-reported pain symptoms; (2) adolescents management of their pain and (3) how to help adolescents manage their pain. Teachers in 5 junior high schools in Norway representing municipalities in 3 rural areas and 2 cities. A qualitative study with an explorative design comprising 5 focus group interviews. Each group consisted of 3-8 junior high school teachers. A semistructured interview guide was used to cover the issues. The transcribed text was analysed with qualitative content analysis. 22 teachers participated (5 men, 17 women; age range 29-62 years) with teaching experience ranging from 3 to nearly 40 years. The main theme describing the experience of teachers with adolescents' pain in everyday life is that pain and management of pain is a social, physical and psychological interwoven phenomenon. Through empirical analyses, 3 subcategories emerged: (1) everyday pain--expressing strenuous life; (2) managing pain--escaping struggle and (3) strategies of teachers--support and normalisation. Teachers have a biopsychosocial understanding and approach to pain experienced by adolescents. This understanding influences the role of teachers as significant others in the lives of adolescents with regard to pain and management of their pain in a school setting.

2011-08-01

Head injuries are the main cause of death in bicycle-related accidents among children and adolescents. According to a Cochrane Review, the risk of head injury (OR 0.31; 95% CI 0.26-0.37) or brain injury (OR 0.31; 95% CI 0.23-0.42) decreases by 69% if a helmet is worn. This study presents the prevalence of helmet use in cycling children and adolescents in Germany and the proportion of head injuries that could be prevented by wearing helmets. The potential effects of increased helmet wearing rates on the population attributable risk percentage for head injuries (PAR%) are demonstrated. The prevalence of helmet use in children aged 3-17 years was analysed using data from the German Health Interview and Examination Survey for Children and Adolescents (KiGGS). The percentage of head injuries preventable by helmet use in this group is estimated by calculating PAR%. Prevalence rates of helmet use and odds ratios from a Cochrane Review about the effectiveness of bicycle helmets for the prevention of head injuries were used for analysis. The potential effect of increased helmet use is shown in 3 scenarios by means of differences of PAR% values in the most relevant age groups. The older the children, the less likely they are to wear a helmet: 89.5% (95% CI 88.0%-90.8%) of the 3- to 6-year-old children wear a helmet when cycling but only 11.0% (95% CI 9.3%-12.9%) of 14- to 17-year-old adolescents do. In the youngest group (3-6 years) 19% of bicycle-related head injuries are attributable to the non-use of helmets, but this proportion rises to 67% in the oldest group (14-17 years). The PAR% of head injuries associated with not wearing a helmet may be reduced by more than a third by increasing the helmet wearing rate to 67% (2 out of 3) among adolescents, and may be reduced to half if 75% of adolescents wore a helmet. Particularly older children and adolescents hardly use bicycle helmets, hence the rate of preventable head injury is high. Efforts towards increasing helmet use should address all age groups with a particular focus on school-aged children and adolescents. © Georg Thieme Verlag KG Stuttgart · New York.

Smoking education and prevention: a developmental model.

PubMed

Oei, T P; Baldwin, A R

1992-01-01

A developmental approach to smoking education and prevention for children and adolescents is proposed. Literature is reviewed concerning the most appropriate agent, content, and presentation, of anti-smoking education for each of three age groups: children to age ten, pre/early adolescents eleven to fifteen, and adolescents fifteen to eighteen. For children to age ten, it is suggested that parents are the best agents of education, with teachers, peers, and the mass media, also playing some role. For pre/early adolescents, peers are suggested as the best agents of education, building onto the earlier and ongoing work of the agents mentioned above. For adolescents, the role of the media hero-figure is discussed. It is emphasized that sources of influence may function additively in affecting the child or adolescent's decisions about smoking, and that education in each stage must build on the stage before.

Little is known about the bio-behavioral mechanisms underlying and differentiating suicide attempts from non-suicidal self-injury (NSSI) in adolescents. Adolescents who attempt suicide or engage in NSSI often report significant interpersonal and social difficulties. Emotional face recognition ability is a fundamental skill required for successful social interactions, and deficits in this ability may provide insight into the unique brain-behavior interactions underlying suicide attempts versus NSSI in adolescents. Therefore, we examined emotional face recognition ability among three mutually exclusive groups: (1) inpatient adolescents who attempted suicide (SA, n = 30); (2) inpatient adolescents engaged in NSSI (NSSI, n = 30); and (3) typically developing controls (TDC, n = 30) without psychiatric illness. Participants included adolescents aged 13-17 years, matched on age, gender and full-scale IQ. Emotional face recognition was evaluated using the diagnostic assessment of nonverbal accuracy (DANVA-2). Compared to TDC youth, adolescents with NSSI made more errors on child fearful and adult sad face recognition while controlling for psychopathology and medication status (ps < 0.05). No differences were found on emotional face recognition between NSSI and SA groups. Secondary analyses showed that compared to inpatients without major depression, those with major depression made fewer errors on adult sad face recognition even when controlling for group status (p < 0.05). Further, compared to inpatients without generalized anxiety, those with generalized anxiety made fewer recognition errors on adult happy faces even when controlling for group status (p < 0.05). Adolescent inpatients engaged in NSSI showed greater deficits in emotional face recognition than TDC, but not inpatient adolescents who attempted suicide. Further results suggest the importance of psychopathology in emotional face recognition. Replication of these preliminary results and examination of the role of context-dependent emotional processing are needed moving forward.

Dental malocclusion is a highly prevalent health condition in adolescence. Patients seek treatment primarily for aesthetic reasons. Therapy benefits are regarded, in the first place, to be psychosocial in nature. Therefore, it is mandatory to consider the perspective of the patient in treatment planning and control using a dental-aesthetics-related quality of life measure. The objective of this study was to investigate whether the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) developed in adult samples including the subscales Dental Self-Confidence, Social Impact, Psychological Impact and Aesthetic Concern is also applicable in adolescents aged 11 years and above. The psychometric properties were examined across three age-groups (11-12, 13-14, 15-17 year olds) with respect to factorial invariance, internal consistency, temporal stability, discriminant validity and gender- or age-associated scale mean differences and item response bias. Participants were 1,112 adolescents recruited from 4 institutions: orthodontic and dental practices, schools, and youth clubs. They answered the 23 partially reformulated items of the PIDAQ. Subjective and dentist evaluations of dental occlusion were assessed using the Perception of Occlusion Scale and the Aesthetic Component of the Index of Orthodontic Treatment Need. Both indices were aggregated to one Malocclusion Index (MI-S and MI-D). The fit indices using confirmatory factor analyses suggested that the factor structure and factor loadings underlying the PIDAQ items were invariant across ages (comparative fit index = 0.91, root-mean-square error of approximation = 0.04). Internal consistency and temporal stability were adequate within the age-groupings (Alpha = 0.71-0.88; intra-class correlations = 0.82-0.96). Adolescents with severe compared to slight malocclusion according to both self-evaluation and dentist evaluation were found to differ in all PIDAQ subscales at a level of p < 0.001 for all ages. PIDAQ scale scores were not related to age and gender. On the item level, no evidence for gender or age bias has been found. The PIDAQ demonstrates to have good psychometric properties in adolescents, independent of their age. The instrument can be applied in making clinical decisions and in the assessment of psychosocial outcomes of orthodontic therapy.

Aim To examine how the experience of genocide in Srebrenica in the early childhood (ages 1-5) influences the psychological health in adolescence. Methods This study included 100 school-attending adolescents, age 15-16 (born in 1990-91) who were divided in two groups according to the place of residence from 1992-1995: the Srebrenica group – adolescents who lived in Srebrenica during the siege and the non-Srebrenica group who lived in the “free territory,” were not wounded, and experienced no losses. We used the socio-demographic questionnaire created for the purposes of our study and the War Trauma Questionnaire, Posttraumatic Stress Reactions Questionnaire, Self-report Depressive Scale (Zung), Freiburg Personality Inventory, and the Lifestyle Questionnaire. Results Srebrenica adolescents experienced significantly more traumatic experiences (14.26 ± 3.11 vs 4.86 ± 3.16, P < 0.001). Although there was no significant difference in the total score of posttraumatic stress reactions and intensity of depression between the two groups, significantly higher scores of posttraumatic stress reaction were noticed for several specific questions. The most prominent defense mechanisms in both groups were projection, intellectualization, and reactive formation. Srebrenica adolescents had higher sociability levels (34.7% vs 16.0%, χ2 = 7.231, P = 0.020). Conclusion Srebrenica adolescents reported significantly more severe PTSD symptoms and significantly greater sociability. Our findings could be used for planning treatment and improving communication and overcoming traumas in war-affected areas. PMID:23444247

Socioeconomic status (SES) is postulated to be a major predictor of dietary intake and nutrition-related knowledge in adults. To date, very few studies have addressed this effect among adolescents. To explore differences in nutrient intake and nutrition-related knowledge among adolescents of contrasting SES in Lebanon. In a cross-sectional survey, 209 males and females, aged 17 to 19 years, were recruited from a private university with high tuition and a free public university in Beirut. The participants completed a multicomponent, self-administered questionnaire that inquired about demographic characteristics and nutrition-related knowledge. Three nonconsecutive 24-hour dietary recalls were obtained through interviews. Energy-adjusted means of dietary intake and age-adjusted nutrition-related knowledge were compared between groups using a general linear model. Adolescents in the high-SES group consumed more vegetables, meats, and fats and oils (p < .05). Energy and nutrient intake analysis showed that adolescents in the high-SES group consumed significantly higher amounts of calories, protein, fat, vitamin A, vitamin C, and iron (p < .001) and significantly lower amounts of carbohydrates (p < .05). Nutritional knowledge, although high among all participants, was higher in the high-SES group (p < .05). Although both groups showed good nutrition-related knowledge, SES significantly affected dietary intake in a sample of Lebanese adolescents. This warrants consideration of other factors, such as cost and environment, that may modulate eating behavior among adolescents from different socioeconomic strata.

Age-Related Effects of Stimulus Type and Congruency on Inattentional Blindness.

Background: Most of the previous inattentional blindness (IB) studies focused on the factors that contributed to the detection of unattended stimuli. The age-related changes on IB have rarely been investigated across all age groups. In the current study, by using the dual-task IB paradigm, we aimed to explore the age-related effects of attended stimuli type and congruency between attended and unattended stimuli on IB. Methods: The current study recruited 111 participants (30 adolescents, 48 young adults, and 33 middle-aged adults) in the baseline recognition experiments and 341 participants (135 adolescents, 135 young adults, and 71 middle-aged adults) in the IB experiment. We applied the superimposed picture and word streams experimental paradigm to explore the age-related effects of attended stimuli type and congruency between attended and unattended stimuli on IB. An ANOVA was performed to analyze the results. Results: Participants across all age groups presented significantly lower recognition scores for both pictures and words in comparison with baseline recognition. Participants presented decreased recognition for unattended pictures or words from adolescents to young adults and middle-aged adults. When the pictures and words are congruent, all the participants showed significantly higher recognition scores for unattended stimuli in comparison with incongruent condition. Adolescents and young adults did not show recognition differences when primary tasks were attending pictures or words. Conclusion: The current findings showed that all participants presented better recognition scores for attended stimuli in comparison with unattended stimuli, and the recognition scores decreased from the adolescents to young and middle-aged adults. The findings partly supported the attention capacity models of IB.

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

Poor diet quality in childhood and adolescence is associated with adverse health outcomes throughout life, yet the dietary habits of American children and how they change across childhood and adolescence are unknown. This study sought to describe diet quality among children and adolescents by assessing adherence to the 2010 Dietary Guidelines for Americans (DGA) and to determine whether any differences in adherence occurred across childhood. We employed a cross-sectional design using data from the National Health and Nutrition Examination Survey (NHANES). Of 9,280 children aged 4 to 18 years who participated in NHANES from 2005 to 2010, those with insufficient data on dietary recall (n=852) or who were pregnant or lactating during the time of interview (n=38) were excluded from the final study sample (n=8,390). We measured adherence to the DGA using the Healthy Eating Index 2010 (HEI-2010) and stratified participants into three age groups (4 to 8, 9 to 13, and 14 to 18 years of age). We analyzed each of 12 HEI-2010 components and total HEI-2010 score. The youngest children had the highest overall diet quality due to significantly greater scores for total fruit, whole fruit, dairy, and whole grains. These children also had the highest scores for sodium, refined grains, and empty calories. Total HEI-2010 scores ranged from 43.59 to 52.11 out of 100, much lower than the minimum score of 80 that is thought to indicate a diet associated with good health. Overall, children and adolescents are failing to meet the DGA and may be at an increased risk of chronic diseases throughout life. By analyzing which food groups show differences between age groups, we provide data that can inform the development of dietary interventions to promote specific food groups targeting specific ages and improve diet quality among children and adolescents.

Aims. The purpose of this pilot trial was to determine the efficacy of sleep promotion program to adapt it for the use of adolescents studying in various schools of Mangalore, India, and evaluate the feasibility issues before conducting a randomized controlled trial in a larger sample of adolescents. Methods. A randomized controlled trial design with stratified random sampling method was used. Fifty-eight adolescents were selected (mean age: 14.02 ± 2.15 years; intervention group, n = 34; control group, n = 24). Self-report questionnaires, including sociodemographic questionnaire with some additional questions on sleep and activities, Sleep Hygiene Index, Pittsburgh Sleep Quality Index, The Cleveland Adolescent Sleepiness Questionnaire, and PedsQL™ Present Functioning Visual Analogue Scale, were used. Results. Insufficient weekday-weekend sleep duration with increasing age of adolescents was observed. The program revealed a significant effect in the experimental group over the control group in overall sleep quality, sleep onset latency, sleep duration, daytime sleepiness, and emotional and overall distress. No significant effect was observed in sleep hygiene and other sleep parameters. All target variables showed significant correlations with each other. Conclusion. The intervention holds a promise for improving the sleep behaviors in healthy adolescents. However, the effect of the sleep promotion program treatment has yet to be proven through a future research. This trial is registered with ISRCTN13083118. PMID:27088040

Bone Health in Adolescent Athletes with a Focus on Female Athlete Triad

Peak bone mass (PBM) is a negative predictor of osteoporosis and life-long fracture risk. Because osteoporosis is such a prevalent disease with life-threatening consequences later in life, it is important to try to maximize PBM. Adolescence is a critical time for bone acquisition. This review discusses some of the differences in male and female skeletal development and modifiable factors that enhance bone accrual in this age group, particularly in athletes. Hormonal influences, physical activity effects, and nutritional contributions are presented, with a focus on the adolescent athlete. Emphasis is placed on the importance of appropriate energy availability in this age group. The Female Athlete Triad (the inter-relationship of decreased energy availability, menstrual irregularity, and low bone density) is an important issue for adolescent, athletic women, and is therefore reviewed, including prevention and treatment strategies. Recommendations for maximizing bone density in both male and female adolescents are discussed. PMID:21378496

There are few data regarding adolescent-onset nephrotic syndrome (NS) and no guidelines for biopsy criteria and treatment protocol. This study was conducted to analyze the clinical spectrum of adolescent-onset NS and evaluate possible biopsy criteria in these children. A prospective analysis was carried out on all patients with idiopathic NS (fulfilling the ISKDC criteria) with onset between 1 and 18 years of age. They were evaluated clinically, followed by biochemical investigations and kidney biopsy. These characteristics of patients with onset between 1 and 12 years (group A) were compared with the same parameters in patients with onset between 12 and 18 years of age (group B) referred to our hospital over the same period. Among all clinical parameters, microhematuria was significantly more prevalent in adolescents (P<0.001). Kidney biopsy was performed in 88% of adolescent patients. Focal segmental glomerulosclerosis (FSGS) was the most-common histopathology in group B (46.3%) compared with minimal change disease (MCD) in group A (42.9%). Group B had a significantly higher frequency of membranoproliferative glomerulonephritis (MPGN) (P<0.005) and a significantly lower frequency of MCD (P<0.001). The biochemical parameters at the onset were similar. On comparing microhematuria, hypertension, and renal insufficiency at presentation, we observed that two or more of these features were present in all patients with MPGN and only in 19.6% of adolescents with MCD, mesangioproliferative glomerulonephritis, and FSGS. The frequency of steroid resistance was significantly higher in group B (P<0.001). In conclusion, adolescent-onset NS differs from the childhood variety in having a significantly higher frequency of hematuria, steroid resistance, and evidence of non-MCD, especially MPGN, on histopathology. Kidney biopsy can be restricted to those adolescents who have at least two abnormal clinical/biochemical features or are steroid non-responders.

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

The goal of this study was to compare the lexical spelling performance of children and adolescents with specific language impairment (SLI) in two contrasting writing situations: a dictation of isolated words (a classic evaluative situation) and a narrative of a personal event (a communicative situation). Twenty-four children with SLI and 48 typically developing children participated in the study, split into two age groups: 7-11 and 12-18 years of age. Although participants with SLI made more spelling errors per word than typically developing participants of the same chronological age, there was a smaller difference between the two groups in the narratives than in the dictations. Two of the findings are particularly noteworthy: (1) Between 12 and 18 years of age, in communicative narration, the number of spelling errors of the SLI group was not different from that of the typically developing group. (2) In communicative narration, the participants with SLI did not make specific spelling errors (phonologically unacceptable), contrary to what was shown in the dictation. From an educational perspective or that of a remediation program, it must be stressed that the communicative narration provides children-and especially adolescents-with SLI an opportunity to demonstrate their improved lexical spelling abilities. Furthermore, the results encourage long-term lexical spelling education, as adolescents with SLI continue to show improvement between 12 and 18 years of age. Copyright © 2013 Elsevier Ltd.

This study aimed to examine the dietary glycaemic index (GI) and glycaemic load (GL) of Australian children and adolescents, as well as the major food groups contributing to GL, in the recent 2011-2012 Australian Health Survey. Plausible food intake data from 1876 children and adolescents (51 % boys), collected using a multiple-pass 24-h recall, were analysed. The GI of foods was assigned based on a step-wise published method using values from common GI databases. Descriptive statistics were calculated for dietary GI, GL and contribution to GL by food groups, stratified by age group and sex. Linear regression was used to test for trends across age groups for BMI, dietary GI and GL, and intakes of energy, nutrients and food groups. Pearson's χ 2 test was used to test for differences between age groups for categorical subject characteristic variables. Mean dietary GI and GL of participants were 55·5 (sd 5·3) and 137·4 (sd 50·8), respectively. The main contributors to dietary GL were starchy foods: breads, cereal-based dishes, breakfast cereals, flours, grains and potatoes accounted for 41 % of total GL. Sweetened beverages, fruit and vegetable juices/drinks, cake-type desserts and sweet biscuits contributed 15 %. No significant difference (at P<0·001) was observed between sexes. In conclusion, Australian children and adolescents appear to consume diets with a lower GI than European children. Exchanging high-GI foods for low-GI alternatives within core and non-core foods may improve diet quality of Australian children and adolescents.

(2) How urgent is the psychosocial need of adolescents to undergo plastic surgery? (3) Which relations exist between bodily attitudes and psychosocial functioning and personality? From 1995 to 1997, 184 plastic surgical patients aged 12 to 22, and a comparison group of 684 adolescents and young adults from the general population aged 12 to 22 years, and their parents, were interviewed and completed questionnaires and standardised rating scales. Adolescents accepted for plastic surgery had realistic appearance attitudes and were psychologically healthy overall. Patients were equally satisfied with their overall appearance as the comparison group, but more dissatisfied with the specific body parts concerned for operation, especially when undergoing corrective operations. Patients had measurable appearance-related psychosocial problems. Patient boys reported less self-confidence on social areas than all other groups. There were very few patient-comparison group differences in correlations between bodily and psychosocial variables, indicating that bodily attitudes and satisfaction are not differentially related to psychosocial functioning and self-perception in patients than in peers. We concluded that adolescents accepted for plastic surgery have considerable appearance-related psychosocial problems, patients in the corrective group reporting more so than in the reconstructive group. Plastic surgeons may assume that these adolescents in general have a realistic attitude towards their appearance. are psychologically healthy, and are mainly dissatisfied about the body parts concerned for operation. corrective patients more so than reconstructive patients. Introverted patients may need more attention from plastic surgeons during the psychosocial assessment.

In the framework of ISAAC-International Studies on Asthma and Allergies in Childhood--the SIDRIA collaborative project--Studi Italiani sui Disturbi Respiratori nell'Infanzia e l'Ambiente--was established in order to estimate the prevalence of asthma, rinithis and eczema in ten geographic areas in Italy. Data collection spanned from October 1994 to March 1995. Overall 18,737 children 6-7 years old in the primary schools and 21,846 adolescents 13-14 years old in the secondary schools entered the study. The parents of pupils in both age groups filled in standardised questionnaires at home; furthermore both a traditional and a video questionnaire was administered at school to the adolescents. The overall response rate was 96.3%. Based on the interviews to the parents a prevalence of asthma of 9.0% in both age groups was estimated, with the lowest values in Cremona (4.6% children; 6.2% adolescents) and the highest in Roma (11.1% children; 10.4% adolescents). Parents also reported a higher prevalence of wheezing (7.7%) and dyspnea (5.3%) in the last year among children than among adolescents (4.7% and 3.4% respectively). Through the direct interview of the adolescents higher prevalence of asthma (10.4%), wheezing (10.3%) and dyspnea (7.8%) were estimated. Within a narrow range of variability, the reported prevalence of asthma and asthmatic symptoms in Trento and Cremona were the lowest and those in Roma, Empoli and Siena the highest. Nor an urban-rural neither a north-south gradient was detected. A higher prevalence of the same disorders was observed among females than males in the youngest age group, but this difference was no more evident among the adolescents.

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

Purpose We examine changes to health insurance coverage and access to health care among children, adolescents, and young adults since the implementation of the Affordable Care Act. Methods Using the National Health Interview Survey, bivariate and logistic regression analyses were conducted to compare coverage and access among children, young adolescents, older adolescents, and young adults between 2010 and 2016. Results We show significant improvements in coverage among children, adolescents, and young adults since 2010. We also find some gains in access during this time, particularly reductions in delayed care due to cost. While we observe few age-group differences in overall trends in coverage and access, our analysis reveals an age-gradient pattern, with incrementally worse coverage and access rates for young adolescents, older adolescents, and young adults. Conclusions Prior analyses often group adolescents with younger children, masking important distinctions. Future reforms should consider the increased coverage and access risks of adolescents and young adults, recognizing that approximately 40% are low income, over a third live in the South, where many states have not expanded Medicaid, and over 15% have compromised health.

Indices predictive of adolescent central obesity include waist circumference (WC), waist-to-hip ratio (WHR) and waist-to-height ratio (WHtR). Such reference data are lacking for Greek adolescents. The aim of this study was to develop age- and gender-specific WC, WHR and WHtR smoothed reference percentiles for abdominal obesity among Greek adolescents aged 12-17 years, to investigate possible obesity cut-offs of WHR and WHtR and to compare WC percentiles to other adolescent populations. A representative sample of 1610 high school adolescents (42.2% boys, 57.8% girls; mean age ± sd 14.4 ± 1.72 years) participated in this cross-sectional study in Attica, Greece, in 2013. Weight, height, body mass index (BMI), WC, hip circumference (HC), WHR and WHtR were measured and percentiles were calculated using the LMS method. The relation between WHR, WHtR and general obesity, as defined by the International Obesity Task Force, was investigated with receiver operating characteristic (ROC) analysis. The discriminating power of WHR and WHtR was expressed as area under the curve (AUC). Greek adolescents' WC measurements at the 50th and 90th percentile were compared with their counterparts' smoothed percentiles from Norway, Turkey, Poland, South India, Germany and Kuwait. Boys had significantly higher mean in all measures than girls, except for BMI where there was no statistical difference in terms of gender. BMI, WC and HC showed an increasing trend with age. WC leveled off in both genders at the age of 17 years. WHR and WHtR showed a continuous decrease with advancing age. WHtR was a better predictor for general obesity in both boys and girls (AUC 95% CI 0.945-0.992) than the WHR (AUC 95% CI 0.758-0.870); the WHtR cut-off of 0.5 had sensitivity 91% and specificity 95% for both genders and all age groups combined. International comparisons showed that Greek adolescents had relatively high levels of abdominal obesity in early-middle adolescence but this did not persist at the age of 17 years. These reference percentile curves could be used provisionally for early detection of abdominal obesity in Greek adolescents aged 12-17 years; WHtR of 0.5 could also be used as a threshold for obesity in this age group.

ABSTRACT The serogroup epidemiology of invasive meningococcal disease (IMD), which varies considerably by geographic region and immunization schedule, changes continuously. Meningococcal carriage data are crucial for assessing IMD epidemiology and designing f potential vaccination strategies. Meningococcal seroepidemiology in Turkey differs from that in other countries: serogroups W and B are the predominant strains for IMD during childhood, whereas no serogroup C cases were identified over the last 10 y and no adolescent peak for IMD was found. There is a lack of data on meningococcal carriage that represents the whole population. The aims of this multicenter study (12 cities in Turkey) were to evaluate the prevalence of Neisseria meningitidis carriage, the serogroup distribution and the related risk factors (educational status, living in a dormitory or student house, being a household contact with Hajj pilgrims, smoking, completion of military service, attending bars/clubs) in 1518 adolescents and young adults aged 10–24 y. The presence of N. meningitidis DNA was tested, and a serogroup analysis was performed using polymerase chain reaction. The overall meningococcal carriage rate was 6.3% (n = 96) in the study population. A serogroup distribution of the 96 N. meningitidis strains isolated from the nasopharyngeal specimens revealed serogroup A in 5 specimens (5.2%), serogroup B in 9 specimens (9.4%), serogroup W in 64 specimens (66.6%), and serogroup Y in 4 specimens (4.2%); 14 were classified as non-grouped (14.4%). No serogroup C cases were detected. The nasopharyngeal meningococcal carriage rate was 5% in the 10–14 age group, 6.4% in the 15–17 age-group, and 4.7% in the 18–20 age group; the highest carriage rate was found in the 21–24 age group (9.1%), which was significantly higher than those of the other age groups (p < 0.05). The highest carriage rate was found in 17-year-old adolescents (11%). The carriage rate was higher among the participants who had had close contact with Hajj/Umrah pilgrims (p < 0.01) or a history of upper respiratory tract infections over the past 3 months (p < 0.05). The nasopharyngeal carriage rate was 6.3% among adolescents and young adults in Turkey and was similar to the recent rates observed in the same age groups in other countries. The most prevalent serogroup was W, and no serogroup C cases were found. In conclusion, the present study found that meningococcal carriage reaches its peak level by age 17, the highest carriage rate was found in 21 - to 24 - year-olds and the majority of the carriage cases were due to serogroup W. Adolescents and young adult carriers seem to be a potential reservoir for the disease, and further immunization strategies, including adolescent immunization, may play a role in the control of IMD.

Inconsistent findings exist regarding long-term substance use (SU) risk for children diagnosed with attention-deficit/hyperactivity disorder (ADHD). The observational follow-up of the Multimodal Treatment Study of Children with ADHD (MTA) provides an opportunity to assess long-term outcomes in a large, diverse sample. Five hundred forty-seven children, mean age 8.5, diagnosed with DSM-IV combined-type ADHD and 258 classmates without ADHD (local normative comparison group; LNCG) completed the Substance Use Questionnaire up to eight times from mean age 10 to mean age 25. In adulthood, weekly marijuana use (32.8% ADHD vs. 21.3% LNCG) and daily cigarette smoking (35.9% vs. 17.5%) were more prevalent in the ADHD group than the LNCG. The cumulative record also revealed more early substance users in adolescence for ADHD (57.9%) than LNCG (41.9%), including younger first use of alcohol, cigarettes, marijuana, and illicit drugs. Alcohol and nonmarijuana illicit drug use escalated slightly faster in the ADHD group in early adolescence. Early SU predicted quicker SU escalation and more SU in adulthood for both groups. Frequent SU for young adults with childhood ADHD is accompanied by greater initial exposure at a young age and slightly faster progression. Early SU prevention and screening is critical before escalation to intractable levels. © 2018 Association for Child and Adolescent Mental Health.

Tendon adaptation due to mechanical loading is controversially discussed. However, data concerning the development of tendon thickness in adolescent athletes is sparse. The purpose of this study was to examine possible differences in Achilles (AT) and patellar tendon (PT) thickness in adolescent athletes while considering age, gender and sport-specific loading. In 500 adolescent competitive athletes of 16 different sports and 40 recreational controls both ATs and PTs were sonographically measured. Subjects were divided into 2 age groups (< 13; ≥ 13 years) and 6 sport type categories (ball, combat, and water sports, combined disciplines, cycling, controls). In addition, 3 risk groups (low, moderate, high) were created according to the athlete's risk of developing tendinopathy. AT and PT thickness did not significantly differ between age groups (AT/PT:<13: 5.4±0.7 mm/3.6±0.5 mm;≥13: 5.3±0.7 mm/3.6±0.5 mm). In both age groups males presented higher tendon thickness than females (p<0.001). AT thickness was highest in ball sports/cyclists and lowest in controls (p≤0.002). PT thickness was greatest in water sports and lowest in controls (p=0.02). High risk athletes presented slightly higher AT thickness compared to the low risk group (p=0.03). Increased AT and PT thickness in certain sport types compared to controls supports the hypothesis of structural tendon adaptation due to sport-specific loading. © Georg Thieme Verlag KG Stuttgart · New York.

The differential effects of Autism and Down's syndrome on sexual behavior.

Although sexuality plays a major role in the socialization of people, few studies have examined the sexual behaviors of individuals with developmental disabilities. Because of this, we decided to investigate sexuality in adolescents with autism spectrum disorder (ASD) and Down's syndrome (Ds) and to compare them with typically developing adolescents, by surveying their parents. Specifically, it was hypothesized that young people with ASD would display lower levels over five domains: social behavior, privacy, sex education, sexual behavior, and parental concerns, than peers with Ds and typically developing young people. In addition, we sought to verify developmental trends in five domains with age for each group. Overall, 269 parents participated; 94 parents of typically developing adolescents, 93 parents of adolescents diagnosed with Ds, and 82 parents of adolescents diagnosed with ASD. Participants were surveyed with a Sexual Behavior Scale developed by Stokes and Kaur [] that assesses parents' reports of their child's: social behavior, privacy awareness, sex education, sexual behavior and parental concerns about the child's behaviors. It was found that three groups were significantly different on all five domains, adolescents with ASD reportedly displaying lower levels than other groups. Moreover, there was a significant improvement in knowledge of privacy and parental concerns with age for adolescents with ASD and a decline in sex education for adolescents with Ds. The results obtained emphasize the need to train adolescents with developmental disability, and especially for adolescents with ASD through sex education programs. © 2015 International Society for Autism Research, Wiley Periodicals, Inc.

“When you got nothing to do, you do somebody”: A Community’s perceptions of neighborhood effects on adolescent sexual behaviors

This study explores community members’ perspectives regarding the relationship between neighborhood characteristics and adolescent sexual behaviors in two rural, African American communities. The data were collected as part of a community needs assessment to inform the development of HIV prevention interventions in two contiguous counties in northeastern North Carolina, USA. We conducted eleven focus groups with three population groups: adolescents and young adults aged 16–24 (N=38), adults over age 25 (N=42), and formerly incarcerated individuals (N=13). All focus groups were audio-recorded, transcribed and analyzed using a grounded theory approach to content analysis and a constant comparison method. Six major themes emerged from the discussions linking neighborhood context and adolescents sexual behavior: the overwhelming absence of recreational options for community members; lack of diverse leisure-time activities for adolescents; lack of recreational options for adolescents who are dating; adolescent access to inappropriate leisure time activities that promote multiple risk behaviors; limited safe environments for socializing; and cost-barriers to recreational activities for adolescents. In addition, lack of adequate parental supervision of adolescents’ time alone and with friends of the opposite sex, as well as ineffective community monitoring of adolescent social activities, were thought to create situations that promoted sexual and other risk behaviors. These findings allowed us to develop a conceptual model linking neighborhood structural and social organization factors to adolescent sexual behaviors and provided insights for developed interventions tailored to the local socioeconomic realities.

Renner, Regina-Maria; de Guzman, Anna; Brahmi, Dalia

Unintended pregnancy among adolescents (10-19years) and young women (20-24years) is a global public health problem. Adolescents face challenges in accessing safe abortion care. To determine, via a systematic data review, whether abortion care for adolescent and young women differs clinically from that for older women. In a comprehensive data review, the Cochrane Central Register of Controlled Trials, MEDLINE, and POPLINE databases were searched from the earliest data entered until November 2012. Randomized controlled trials and observational studies comparing effectiveness, safety, acceptability, and long-term sequelae of abortion care between adolescent/young women and older women were identified. Two reviewers independently extracted data, and the Cochrane guidelines and Newcastle-Ottawa Scale were used for quality assessment. In total, there were 25 studies including 346 000 women undergoing first- and second-trimester medical abortion, vacuum aspiration, or dilation and evacuation. Effectiveness and overall complications were similar among age groups. However, younger women had an increased risk for cervical laceration and a decreased risk of uterine perforation and mortality. Satisfaction and long-term depression were similar between age groups. Except for less uptake of intrauterine devices among adolescents, age did not affect post-abortion contraception. Evidence from various healthcare systems indicates that abortion is safe and efficacious among adolescent and young women. Clinical services should promote access to safe abortion for adolescents. © 2013.

Although food hypersensitivity is a public health concern, its documentation among the elderly is limited. The current study aims to compare the prevalence and characteristics of food hypersensitivity among adolescent women between aged 18-24 with among older women >50 years of age. 660 female university students between the ages of 18 and 24 who volunteered were enrolled as adolescent subjects. 470 women >50 years old who visited the Health Care Centre of Kyoto Katsura Hospital for health check-ups were enrolled as the older subjects. A questionnaire created by ourselves asking the presence of food hypersensitivity, symptoms, causative food, personal or family history of other allergic disorders was distributed. The prevalence of food hypersensitivity was statistically similar between adolescent (8.2%) and older women (8.9%). Among them, only 24.1% of the adolescent women and 26.2% of the older women had been diagnosed by physicians as having food allergy. The main causative foods (fruits, shellfish and fish) and the manifestations relating to food hypersensitivity were almost identical between adolescent and older women. In both adolescent and older women, food hypersensitivity positive group showed significantly higher prevalence of personal or family history of allergic disorders than that in food hypersensitivity negative group. These data indicate that food hypersensitivity in older women should be given more attention because the prevalence of this condition was as common as that in adolescent women.

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

2015-12-01

To analyze the differences between the bacterial diversities in the saliva of caries-free and caries-susceptible adolescents through polymerase chain reaction (PCR)-denaturing gradient gel electrophoresis (DGGE). Twenty adolescent subjects aged 12-18 years were recruited and subdivided into two groups: caries-free adolescents (n = 10) and caries-susceptible adolescents (n = 10). Saliva samples were collected. Total DNA was isolated directly from each sample. A portion of the 16S rRNA gene locus was PCR-amplified by using universal primers. Microbial diversity was analyzed through PCR-DGGE. Analyzing the DGGE profile, we found that the composition of the saliva microbiome exhibited great intra-individual differences; the average band numbers of the caries-free adolescent group and the caries-susceptible adolescent group were 32.5 ± 3.7 and 27.3 ± 3.4, respectively. The differences between the groups were statistically significant (P = 0.008). Shannon-Wiener's indexes of the caries-susceptible adolescent group and the caries-free adolescent group were 2.5 ± 0.2 and 2.6 ± 0.2, respectively, but the differences between the groups were not significant (P = 0.405). Clustering analysis results suggested that most of the samples in the same group clustered together; this observation showed a high community structure similarity. The microbial diversity and complexity of bacteria in saliva are significantly higher in caries-free adolescents than in caries-susceptible adolescents. During caries development, bacterial diversity in the saliva likely decreases.

This study aims to describe psychological problems, self-esteem difficulties and body dissatisfaction in a sample of adolescents with acquired brain lesions and to compare them with an age- and gender-matched control group. In an experimental design, the psychological profile of 26 adolescents with brain lesions of traumatic or vascular aetiology, aged 12-18 years, was compared with that of 18 typically-developing subjects. Moreover, within the clinical group, patients with TBI were compared with patients with vascular lesions. The psychological and adaptive profile of the adolescents was assessed by a specific protocol, including CBCL, VABS, RSES, EDI-2 and BES. Adolescents with brain lesions showed more marked psychological problems than their healthy peers; they also presented with a greater impairment of adaptive skills and a lower self-esteem. No significant differences were found between patients with traumatic lesions and patients with vascular lesions. Adolescents with acquired brain lesions were at higher risk to develop psychological and behavioural difficulties. Furthermore, in the clinical sample, some variables such as the long hospitalization and isolation from family and peers were associated to a greater psychological burden than the aetiology of the brain damage.

Subclinical depressive symptoms in adolescents are associated with a host of impairments and constitute a risk factor for future depression. The aim of the present study was to study the efficacy of a school-based group coping skills program for Indian adolescents with subclinical depression. Adolescents (n = 120) across two schools comprised the intervention and control groups and were assessed at baseline, post-intervention, and 3 months no-contact follow-up. The intervention group adolescents received the 8-weekly Coping Skills program in same-gender groups of 4-8 adolescents each, and the control group adolescents received one interactive psycho-educatory session. The intervention group evidenced clinically significant reductions in depressive symptoms, negative cognitions, and academic stress, and increased social problem solving and coping skills, at both post-intervention and follow-up. With regard to moderators, initial levels of depressive symptoms and homework compliance were found to partially moderate the effect of intervention. No effects were found for parental depression, gender, and age. The present study calls for future development and implementation of programs to address subclinical psychopathology among adolescents in Indian schools. Copyright © 2018 Elsevier B.V.

2015-04-01

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

2005-08-01

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

This study examines explicit memory bias for emotional information in children and adolescents with major depressive disorder (MDD). Participants were a convenient sample of 28 children and adolescents of mothers with MDD, 28 children and adolescents with MDD, and 29 healthy controls. Their age range was 11-17 years old. The groups were matched for gender ratio, mean age, and the years of educational level. They were assessed by the Recall Task. Emotional stimuli consisted of three sets of words namely sad, happy, and neutral words. Children and adolescents of mothers with MDD similar to children and adolescents with MDD recalled more sadness stimuli in comparison with the controls. In other words, they showed an explicit memory bias towards sad stimuli. Also, healthy children significantly recalled more happy words than the other two groups. There was no significant difference among the three groups for the recall of neutral stimuli. Current findings support that there is a recall memory bias for emotional information in children with MDD. These children more than healthy children recall sad words. Moreover, healthy children recall happy words more than children with MDD. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

We sought to identify regional and seasonal variation in not meeting physical activity (PA) recommendations of ≥60 min a day of moderate-to-vigorous PA (MVPA) and 3 h of vigorous PA per week (VPA) in a longitudinal cohort of United States (US) adolescents. Participants in the Growing Up Today Study 2, a prospective study of 10,918 adolescents, self-reported season-specific weekly hours of MVPA and VPA from 2004 through 2011. To assess variation in PA by climate, we grouped the contiguous US into nine climatically consistent geographic regions. We also examined MVPA and VPA by season, sex, ethnicity, weight status, and age group. The majority (85%) of adolescents did not meet the MVPA recommendation, and 91% did not meet the VPA recommendation, for one or more seasons over the four study years. Across all climate regions, adolescents were two times more likely to not meet the MVPA recommendation during the winter compared to summer (odds ratio 2.02, 95% confidence interval: 1.96-2.08). Regardless of climate region, gender, ethnicity, or age group, adolescents were more likely not to meet MVPA or VPA recommendations in the winter than the summer. Adolescents may benefit from interventions aimed at increasing PA in the winter.

Close friendships become important at middle-school age and are unexplored in adolescents born prematurely. The study aimed to characterize friendship behaviors of formerly preterm infants at age 12 and explore similarities and differences between preterm and full-term peers on dyadic friendship types. From the full sample of N = 186, one hundred sixty-six 12-year-old adolescents (40 born full term, 126 born preterm) invited a close friend to a 1.5 hour videotaped laboratory play session. Twenty adolescents were unable to participate due to scheduling conflicts or developmental disability. Characteristic friendship behaviors were identified by Q-sort followed by Q-factoring analysis. Friendship duration, age, and contact differed between the full-term and preterm groups but friendship activities, behaviors, and quality were similar despite school service use. Three Q-factors, leadership, distancing, and mutual playfulness, were most characteristic of all dyads, regardless of prematurity. These prospective, longitudinal findings demonstrate diminished prematurity effects at adolescence in peer friendship behavior and reveal interpersonal dyadic processes that are important to peer group affiliation and other areas of competence.

2012-06-12

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

2002-01-01

The purpose of this study was to investigate if adolescents with cleft lip, or palate, or both (CLP), have an altered self-concept, and to assess their degree of introversion, compared with a control group. The CLP group consisted of 55 adolescents (aged 17-20 years) and the control group consisted of 31 adolescents (16-19 years). The Tennessee Self Concept Scale (TSCS) was used to measure the subjects' self-concept, while the Eysenck Personality Questionnaire Inventory (EPQ-I) was used to measure introversion. The results indicate that those with CLP have a normal or even a high self-concept, and no signs of introversion.

While young racial/ethnic groups are the fastest growing population in the United States, data about substance-related disorders among adolescents of various racial/ethnic backgrounds are lacking. To examine the magnitude of past-year DSM-IV substance-related disorders (alcohol, marijuana, cocaine, inhalants, hallucinogens, heroin, analgesic opioids, stimulants, sedatives, and tranquilizers) among adolescents of white, Hispanic, African American, Native American, Asian or Pacific Islander, and multiple race/ethnicity. The 2005 to 2008 National Survey on Drug Use and Health. Academic research. Noninstitutionalized household adolescents aged 12 to 17 years. Substance-related disorders were assessed by standardized survey questions administered using the audio computer-assisted self-interviewing method. Of 72 561 adolescents aged 12 to 17 years, 37.0% used alcohol or drugs in the past year; 7.9% met criteria for a substance-related disorder, with Native Americans having the highest prevalence of use (47.5%) and disorder (15.0%). Analgesic opioids were the second most commonly used illegal drugs, following marijuana, in all racial/ethnic groups; analgesic opioid use was comparatively prevalent among adolescents of Native American (9.7%) and multiple race/ethnicity (8.8%). Among 27 705 past-year alcohol or drug users, Native Americans (31.5%), adolescents of multiple race/ethnicity (25.2%), adolescents of white race/ethnicity (22.9%), and Hispanics (21.0%) had the highest rates of substance-related disorders. Adolescents used marijuana more frequently than alcohol or other drugs, and 25.9% of marijuana users met criteria for marijuana abuse or dependence. After controlling for adolescents' age, socioeconomic variables, population density of residence, self-rated health, and survey year, adjusted analyses of adolescent substance users indicated elevated odds of substance-related disorders among Native Americans, adolescents of multiple race/ethnicity, adolescents of white race/ethnicity, and Hispanics compared with African Americans; African Americans did not differ from Asians or Pacific Islanders. Substance use is widespread among adolescents of Native American, white, Hispanic, and multiple race/ethnicity. These groups also are disproportionately affected by substance-related disorders.

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

Adolescence is a distinct developmental period characterized by behavioral and physiological maturation. Rapid ongoing changes during neurodevelopment in particular present potential opportunities for stress to have lasting effects on longitudinal outcomes of behavioral and neuroendocrine function. While adult stress effects on outcomes during adulthood have been characterized, little is known about the lasting effects of adolescent repeated stressor exposure on outcomes during adolescence. We have previously reported different stress responses in adolescent rats relative to adult rats, including a blunted fear response outcome in adulthood in rats stressed during adolescence. The present study characterized the ontogeny of behavioral and neuroendocrine responses to eight underwater trauma (UWT) exposures in rats over a two week poststress time period during adolescence (P34) or adulthood (P83) relative to age-matched control groups that underwent eight swimming episodes without UWT. Repeated UWT exposures starting in adolescence, but not adulthood, resulted in adverse behavioral responses on the elevated plus maze 1 day post-stress. Corticosterone responses did not differ between UWT-exposed and controls for either age group at 1 day or at 7 days poststress, although there was an effect of age on corticosterone levels. We conclude that repeated UWT stress events have a lasting, negative behavioral effect on adolescent rats that is not observed in adult rats after the two-week exposure window. These results suggest that neurophysiological mechanisms underlying recovery from a repeated stressor are immature in adolescence relative to adulthood in rats.

In Manitoba, Canada, school-based clinics providing sexual and reproductive health services for adolescents have been implemented to address high rates of sexually transmitted infections (STIs) and pregnancies. The objectives of this population-based study were to compare pregnancy and STI rates between adolescents enrolled in schools with school-based clinics, those in schools without clinics, and those not enrolled in school. Data were from the PATHS Data Resource held in the Population Health Research Data Repository housed at the Manitoba Centre for Health Policy. Adolescents aged 14 to 19 between 2003 and 2009 were included in the study. Annualized rates of pregnancies and positive STI tests were estimated and Poisson regression models were used to test for differences in rates amongst the three groups. As a proportion, pregnancies among non-enrolled female adolescents accounted for 55 % of all pregnancies in this age group during the study period. Pregnancy rates were 2-3 times as high among non-enrolled female adolescents. Compared to adolescents enrolled in schools without school-based clinics, age-adjusted STI rates were 3.5 times (p < .001) higher in non-enrolled males and 2.3 times (p < .001) higher in non-enrolled females. The highest rates for pregnancies and STIs were observed among non-enrolled adolescents. Although provision of reproductive and health services to in-school adolescents should remain a priority, program planning and design should consider optimal strategies to engage out of school youth.

Objective To investigate development of cognitive and motor functions in healthy adolescents and to explore whether hazardous drinking affects the normal developmental course of those functions. Method Participants were 831 adolescents recruited across five United States sites of the National Consortium on Alcohol and NeuroDevelopment in Adolescence (NCANDA): 692 met criteria for no/low alcohol exposure, and 139 exceeded drinking thresholds. Cross-sectional, baseline data were collected with computerized and traditional neuropsychological tests assessing eight functional domains expressed as composite scores. General additive modeling evaluated factors potentially modulating performance (age, sex, ethnicity, socioeconomic status, and pubertal developmental stage). Results Older no/low-drinking participants achieved better scores than younger ones on five Accuracy composites (General Ability, Abstraction, Attention, Emotion, and Balance). Speeded responses for Attention, Motor Speed, and General Ability were sensitive to age and pubertal development. The exceeds-threshold group (accounting for age, sex, and other demographic factors) performed significantly below the no/low-drinking group on Balance accuracy and on General Ability, Attention, Episodic Memory, Emotion, and Motor speed scores and showed evidence for faster speed at the expense of accuracy. Delay Discounting performance was consistent with poor impulse control in the younger no/low drinkers and in exceeds-threshold drinkers regardless of age. Conclusions Higher achievement with older age and pubertal stage in General Ability, Abstraction, Attention, Emotion, and Balance suggests continued functional development through adolescence, possibly supported by concurrently maturing frontal, limbic, and cerebellar brain systems. Whether low scores by the exceeds-threshold group resulted from drinking or from other pre-existing factors requires longitudinal study. PMID:26752122

Parenting practices and peer group affiliation in adolescence.

PubMed

Brown, B B; Mounts, N; Lamborn, S D; Steinberg, L

1993-04-01

Social scientists have often assumed that parental influence is sharply curtailed at adolescence because of the rising counterinfluence of peer groups, over which parents have little control. The present study tested a conceptual model that challenged this view by arguing that parents retain a notable but indirect influence over their teenage child's peer associates. Data from a sample of 3,781 high school students (ages 15-19) indicated that specific parenting practices (monitoring, encouragement of achievement, joint decision making) were significantly associated with specific adolescent behaviors (academic achievement, drug use, self-reliance), which in turn were significantly related to membership in common adolescent crowds (jocks, druggies, etc). Findings encourage investigators to assess more carefully parents' role in adolescents' peer group affiliations.

Epidemiological data indicate that risk behaviors are among the leading causes of adolescent morbidity and mortality worldwide. Consistent with this, laboratory-based studies of age differences in risk behavior allude to a peak in adolescence, suggesting that adolescents demonstrate a heightened propensity, or inherent inclination, to take risks. Unlike epidemiological reports, studies of risk taking propensity have been limited to Western samples, leaving questions about the extent to which heightened risk taking propensity is an inherent or culturally constructed aspect of adolescence. In the present study, age patterns in risk-taking propensity (using two laboratory tasks: the Stoplight and the BART) and real-world risk taking (using self-reports of health and antisocial risk taking) were examined in a sample of 5227 individuals (50.7% female) ages 10-30 (M = 17.05 years, SD = 5.91) from 11 Western and non-Western countries (China, Colombia, Cyprus, India, Italy, Jordan, Kenya, the Philippines, Sweden, Thailand, and the US). Two hypotheses were tested: (1) risk taking follows an inverted-U pattern across age groups, peaking earlier on measures of risk taking propensity than on measures of real-world risk taking, and (2) age patterns in risk taking propensity are more consistent across countries than age patterns in real-world risk taking. Overall, risk taking followed the hypothesized inverted-U pattern across age groups, with health risk taking evincing the latest peak. Age patterns in risk taking propensity were more consistent across countries than age patterns in real-world risk taking. Results suggest that although the association between age and risk taking is sensitive to measurement and culture, around the world, risk taking is generally highest among late adolescents.

Internet Use Disorder (IUD) affects numerous adolescents worldwide, and (Internet) Gaming Disorder, a specific subtype of IUD, has recently been included in DSM-5 and ICD-11. Epidemiological studies have identified prevalence rates up to 5.7% among adolescents in Germany. However, little is known about the risk development during adolescence and its association to education. The aim of this study was to: (a) identify a clinically relevant latent profile in a large-scale high-school sample; (b) estimate prevalence rates of IUD for distinct age groups and (c) investigate associations to gender and education. N = 5387 adolescents out of 41 schools in Germany aged 11-21 were assessed using the Compulsive Internet Use Scale (CIUS). Latent profile analyses showed five profile groups with differences in CIUS response pattern, age and school type. IUD was found in 6.1% and high-risk Internet use in 13.9% of the total sample. Two peaks were found in prevalence rates indicating the highest risk of IUD in age groups 15-16 and 19-21. Prevalence did not differ significantly between boys and girls. High-level education schools showed the lowest (4.9%) and vocational secondary schools the highest prevalence rate (7.8%). The differences between school types could not be explained by academic level.

To compare different methods of screening for blood pressure disorders in children and adolescents. A database with 17,083 medical records of patients from a pediatric cardiology clinic was used. After analyzing the inclusion and exclusion criteria, 5,650 were selected. These were divided into two age groups: between 5 and 13 years and between 13 and 18 years. The blood pressure measurement was classified as normal, pre-hypertensive, or hypertensive, consistent with recent guidelines and the selected screening methods. Sensitivity, specificity, and accuracy were then calculated according to gender and age range. The formulas proposed by Somu and Ardissino's table showed low sensitivity in identifying pre-hypertension in all age groups, whereas the table proposed by Kaelber showed the best results. The ratio between blood pressure and height showed low specificity in the younger age group, but showed good performance in adolescents. Screening tools used for the assessment of blood pressure disorders in children and adolescents may be useful to decrease the current rate of underdiagnosis of this condition. The table proposed by Kaelber showed the best results; however, the ratio between BP and height demonstrated specific advantages, as it does not require tables.

Objective: To evaluate the presence of family breakdown factors among eutrophic and overweight/obese adolescents. Methods: Cross-sectional study of 242 students aged between 14 and 19 years old, from a public school. Each student was weighed, measured and answered a questionnaire with closed questions addressing the presence of family breakdown factors. The adolescents were divided in two groups: euthophic and overweight/obese. The answers of both groups were compared by Fisher's exact and Mann-Whitney tests. Results: There was no statistically significant difference in the prevalence of the studied factors between the two groups. Comparing the number of positive answers (presence of family breakdown factors) and negative ones (absence of family breakdown factors), no difference was observed between the groups. Conclusions: The inclusion of a control group showed that factors of family breakdown, usually identified as associated with obesity in adolescents, may also be present in eutrophic adolescents.

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

This study explores community members' perspectives regarding the relationship between neighborhood characteristics and adolescent sexual behaviors in two rural, African American communities. The data were collected as part of a community needs assessment to inform the development of HIV prevention interventions in two contiguous counties in northeastern North Carolina, USA. We conducted eleven focus groups with three population groups: adolescents and young adults aged 16-24 (N = 38), adults over age 25 (N = 42), and formerly incarcerated individuals (N = 13). All focus groups were audio-recorded, transcribed and analyzed using a grounded theory approach to content analysis and a constant comparison method. Six major themes emerged from the discussions linking neighborhood context and adolescents sexual behavior: the overwhelming absence of recreational options for community members; lack of diverse leisure-time activities for adolescents; lack of recreational options for adolescents who are dating; adolescent access to inappropriate leisure time activities that promote multiple risk behaviors; limited safe environments for socializing; and cost-barriers to recreational activities for adolescents. In addition, lack of adequate parental supervision of adolescents' time alone and with friends of the opposite sex, as well as ineffective community monitoring of adolescent social activities, were thought to create situations that promoted sexual and other risk behaviors. These findings allowed us to develop a conceptual model linking neighborhood structural and social organization factors to adolescent sexual behaviors and provided insights for developing interventions tailored to address local socioeconomic realities.

Transformational leadership is conceptualized as a set of behaviors designed to inspire, energize and motivate others to achieve higher levels of functioning, and is associated with salient health-related outcomes in organizational settings. Given (a) the similarities that exist between leadership within organizational settings and parenting within families, and (b) the importance of the family environment in the promotion of adolescent health-enhancing behaviors, the purpose of this exploratory study was to examine the cross-sectional relationships between parents' transformational leadership behaviors and adolescent dietary and physical activity behaviors. 857 adolescents (aged 13-15, mean age = 14.70 yrs) completed measures of transformational parenting behaviors, healthful dietary intake and leisure-time physical activity. Regression analyses were conducted to examine relationships between family transformational leadership and adolescent health outcomes. A further 'extreme group analysis' was conducted by clustering families based on quartile splits. A MANCOVA (controlling for child gender) was conducted to examine differences between families displaying (a) HIGH levels of transformational parenting (consistent HIGH TP), (b) LOW levels of transformational parenting (consistent LOW TP), and (c) inconsistent levels of transformational parenting (inconsistent HIGH-LOW TP). Results revealed that adolescents' perceptions of family transformational parenting were associated with both healthy dietary intake and physical activity. Adolescents who perceived their families to display the highest levels of transformational parenting (HIGH TP group) displayed greater healthy eating and physical activity behaviors than adolescents who perceived their families to display the lowest levels of transformational parenting behaviors (LOW TP group). Adolescents who perceived their families to display inconsistent levels of transformational parenting behaviors (HIGH-LOW TP group) displayed the same levels of healthy eating behaviors as those adolescents from the LOW TP group. For physical activity behaviors, adolescents who perceived their families to display inconsistent levels of transformational parenting behaviors (HIGH-LOW TP group) did not differ in terms of physical activity than those in either the HIGH TP or LOW TP group. Family transformational parenting behaviors were positively associated with both healthful dietary intake and leisure-time physical activity levels amongst adolescents. The findings suggest that transformational leadership theory is a useful framework for understanding the relationship between family leadership behaviors and adolescent health outcomes.

Fluid intake, especially water, is essential for human life and also necessary for physical and mental function. The present study aimed to assess beverage consumption across age groups. A systematic review was conducted. Original research in English language publications and available studies (or abstracts in English) from 2000 to 2013 was searched for by using the medical subheading (MeSH) terms: ('beverage' OR 'fluid' [Major]) AND ('consumption' [Mesh] OR 'drinking' [Mesh] OR 'intake' [Mesh]) AND ('child' [Mesh] OR 'adolescent' [Mesh] OR 'adult' [Mesh]). Article selection was restricted to those papers covering healthy populations of all age groups in a nationwide sample, or from a representative sample of the population of a city or cities, which examined the trends or patterns of beverage intake and the determinants of beverage intake. Sixty-five studies were identified with respect to beverage consumption across age groups. The papers were screened by thoroughly reading titles or abstracts. Full-text articles were assessed by three investigators. Total beverage intake varied between 0.6 and 3.5 L day(-1) among all age groups (males more than females). Plain water contributed up to 58%, 75% and 80% of the total beverage intake in children, adolescents and adults, respectively. Milk consumption was higher among children; consumption of soft drinks was higher among adolescents; and the consumption of tea, coffee and alcoholic beverages was higher among adults. Plain water is the main water source for all age groups and the consumption of other beverages varies according to age. © 2014 The British Dietetic Association Ltd.

While actigraphy has gained popularity in pediatric sleep research, questions remain about the validity of actigraphy as an estimate of sleep-wake patterns. In particular, there is little consistency in the field in terms of scoring rules used to determine sleep onset latency. The purpose of this study was to evaluate different criteria of immobility as a measure of sleep onset latency in children and adolescents. Ninety-five youth (ages 3-17 years, 46 % male) wore both the Ambulatory Monitoring Inc. Motionlogger Sleep Watch (AMI) and the Philips Respironics Mini-Mitter Actiwatch-2 (PRMM) during overnight polysomnography in a pediatric sleep lab. We examined different sleep onset latency scoring rules (3, 5, 10, 15, and 20 min of immobility) using different algorithms (Sadeh and Cole-Kripke) and sensitivity settings (low, medium, high) for the devices. Comparisons were also made across age groups (preschoolers, school-aged, adolescents) and sleep disordered breathing status (no obstructive sleep apnea [OSA], mild OSA, clinically significant OSA). For the AMI device, shorter scoring rules performed best for children and longer scoring rules were better for adolescents, with shorter scoring rules best across sleep disordered breathing groups. For the PRMM device, medium to longer scoring rules performed best across age and sleep disordered breathing groups. Researchers are encouraged to determine the scoring rule that best fits their population of interest. Future studies are needed with larger samples of children and adolescents to further validate actigraphic immobility as a proxy for sleep onset latency.

Risk activities for acquisition of the human immunodeficiency virus (HIV) remain prevalent among urban adolescents. While interdisciplinary approaches to examine the variables contributing to risk/protective behaviors have been promoted, strategies for such explorations require further formulation. Recently we employed focus group discussions to explore factors placing urban adolescents at risk for engaging in HIV risk behaviors. The focus group format enables substantial interaction on a topic in a limited time period, but does not always provide expression of the full range of behavioral options. In this study we investigated the use of pile-sorts for confirmation of impressions from focus group discussions among 57 urban youths aged 10-14. The pile-sorts revealed some support for most of the views expressed in the group discussions. However, the sorts revealed more variability in views than was expressed in the group discussions. Substantial gender and age-based differences in perceptions were revealed with potentially important intervention implications.

Everyday memory and working memory in adolescents with mild intellectual disability.

2010-05-01

Everyday memory and its relationship to working memory was investigated in adolescents with mild intellectual disability and compared to typically developing adolescents of the same age (CA) and younger children matched on mental age (MA). Results showed a delay on almost all memory measures for the adolescents with mild intellectual disability compared to the CA control adolescents. Compared to the MA control children, the adolescents with mild intellectual disability performed less well on a general everyday memory index. Only some significant associations were found between everyday memory and working memory for the mild intellectual disability group. These findings were interpreted to suggest that adolescents with mild intellectual disability have difficulty in making optimal use of their working memory when new or complex situations tax their abilities.

To explore parental and adolescent views on the confidential interview in the gynecologic setting and compare adolescent reported risk-taking behaviors with parental perception. Anonymous surveys were administered separately to parents/guardians and adolescents between the ages of 11-17. Information pertaining to the patient's Tanner stage and reason for visit was obtained from the provider. This first phase served as the usual care group. In the second phase of the study, surveys were once again distributed after a brief educational intervention. Linear regression analysis, Wilcoxon rank sum test, and Fisher exact test were used where appropriate. Pediatric and Adolescent Gynecology clinics in two tertiary hospitals INTERVENTION: Brief educational handout on key concepts of the confidential interview MAIN OUTCOME MEASURES: Parental perception of the confidential interview and adolescent risk- taking behaviors RESULTS: A total of 248 surveys were included in the final analysis, which accounts for 62 adolescent and parent/guardian pairs in each group. The majority of parents and adolescents reported perceived benefit to the confidential interview. However, parents were less likely to rate benefits of private time specifically for their own adolescent and less than half of parents believed that adolescents should have access to private time in the gynecologic setting. Both parents/guardians and adolescents feared that the confidential interview would limit the parent's ability to take part in decision-making. The low support for confidential time for their adolescent was not different in the usual care group as compared to the intervention group, although there was a trend toward parental acceptance with increased adolescent age. Adolescents were consistently more likely to report more risk-taking behaviors than their parents perceived. There is a discord between parental perception and adolescent reports of risk taking behaviors. This is coupled with a lack of understanding or comfort regarding the benefits of the confidential interview among parents and adolescents presenting for gynecologic care. A short educational intervention had only a modest impact on parental perceptions regarding the confidential interview. Copyright © 2018. Published by Elsevier Inc.

Maintenance of appropriate A1C values and minimization of hyperglycemic excursions are difficult for many pediatric patients with type 1 diabetes. Continuous glucose monitoring (CGM) sensor-augmented pump (SAP) therapy is an alternative to multiple daily injection (MDI) therapy in this population. Sensor-augmented pump therapy for A1C reduction (STAR 3) was a 1-yr trial that included 82 children (aged 7-12) and 74 adolescents (aged 13-18) with A1C values ranging from 7.4 to 9.5% who were randomized to either SAP or MDI therapy. Quarterly A1C values were obtained from all subjects. CGM studies were carried out at baseline, 6 months, and 12 months to quantify glycemic excursions [calculated as area under the glucose concentration-time curve (AUC)] and variability. In the SAP group, sensor compliance was recorded. Baseline A1C values were similar in subjects randomized to the SAP (8.26 ± 0.55%) and MDI groups (8.30 ± 0.53%). All subsequent A1C values showed significant (p < 0.05) treatment group differences favoring SAP therapy. Compared with the MDI group, subjects in the SAP group were more likely to meet age-specific A1C targets and had lower AUC values for hyperglycemia with no increased risk of hypoglycemia. Glucose variability improved in the SAP group compared to the MDI group. Children wore CGM sensors more often and were more likely to reach age-specific A1C targets than adolescents. SAP therapy allows both children and adolescents with marginally or inadequately controlled type 1 diabetes to reduce A1C values, hyperglycemic excursions, and glycemic variability in a rapid, sustainable, and safe manner. © 2011 John Wiley & Sons A/S.

Yoga reduces performance anxiety in adolescent musicians.

2013-01-01

Professional musicians often experience high levels of stress, music performance anxiety (MPA), and performance-related musculoskeletal disorders (PRMDs). Given the fact that most professional musicians begin their musical training before the age of 12, it is important to identify interventions that will address these issues from an early age. This study intended to replicate and expand upon adult research in this area by evaluating the effects of a yoga intervention on MPA and PRMDs in a population of adolescent musicians. The present study was the first to examine these effects. The research team assigned participants, adolescent musicians, into two groups. The intervention group (n = 84) took part in a 6-wk yoga program, and the control group (n = 51) received no treatment. The team evaluated the effects of the yoga intervention by comparing the scores of the intervention group to those of the control group on a number of questionnaires related to MPA and PRMDs. The study was conducted at the Boston University Tanglewood Institute (BUTI). BUTI is a training academy for advanced adolescent musicians, located in Lenox, Massachusetts. Participants were adolescent, residential music students (mean age = 16 y) in a 6-wk summer program at the BUTI in 2007 and 2008. Participants in the yoga intervention group were requested to attend three, 60-min, Kripalustyle yoga classes each wk for 6 wk. MPA was measured using the Performance Anxiety Questionnaire (PAQ) and the Music Performance Anxiety Inventory for Adolescents (MPAI-A). PRMDs were measured using the Performance-Related Musculoskeletal Disorders Questionnaire (PRMD-Q). RESULTS • Yoga participants showed statistically significant reductions in MPA from baseline to the end of the program compared to the control group, as measured by several subscales of the PAQ and MPAI-A; however, the results for PRMDs were inconsistent. The findings suggest that yoga may be a promising way for adolescents to reduce MPA and perhaps even prevent it in the future. These findings also suggest a novel treatment modality that potentially might alleviate MPA and prevent the early disruption and termination of musical careers.

An ethno-epidemiological study was carried out with adolescent women who have been studied since birth. In 2001, all female adolescents from the 1982 Pelotas Birth Cohort were identified in 27% of all census tracts in Pelotas, Rio Grande do Sul State. Risk factors for childbearing during adolescence were investigated using a case-control approach. Cases (n = 420) were identified through the local live birth information system, and controls included 408 women who had not given birth by 2001. To understand social and cultural factors related to childbearing during adolescence, an ethnographic study focused on 23 young women from the case group. Work, schooling, sexuality, and reproductive health were analyzed using an ethno-epidemiological approach. Socioeconomic variables like work and schooling were strongly associated with childbearing in adolescence. An inverse linear association was observed between age at first dating and childbearing during adolescence (p < 0.001). Focusing on the contexts and social values (traditional and/or modern), pregnancy was: a positive consequence of an affective relationship with the partner; a way of exposing adolescent sexuality; and a means to achieve a certain social autonomy and other forms of social status within the age group.

Autism spectrum disorder is a complex condition that requires specialised care. Knowledge of the costs of autism spectrum disorder, especially in comparison with other conditions, may be useful to galvanise policymakers and leverage investment in education and intervention to mitigate aspects of autism spectrum disorder that negatively impact individuals with the disorder and their families. This article describes the services and associated costs for four groups of individuals: adolescents with autistic disorder, adolescents with other autism spectrum disorders, adolescents with other special educational needs and typically developing adolescents using data from a large, well-characterised cohort assessed as part of the UK Special Needs and Autism Project at the age of 12 years. Average total costs per participant over 6 months were highest in the autistic disorder group (£11,029), followed by the special educational needs group (£9268), the broader autism spectrum disorder group (£8968) and the typically developing group (£2954). Specialised day or residential schooling accounted for the vast majority of costs. In regression analysis, lower age and lower adaptive functioning were associated with higher costs in the groups with an autism spectrum disorder. Sex, ethnicity, number of International Classification of Diseases (10th revision) symptoms, autism spectrum disorder symptom scores and levels of mental health difficulties were not associated with cost. © The Author(s) 2014.

Objective Poor threat-safety discrimination reflects prefrontal cortex dysfunction in adult anxiety disorders. While adolescent anxiety disorders are impairing and predict high risk for adult anxiety disorders, no prior study examines neural correlates of threat-safety discrimination in this group. The current study compares prefrontal cortex function in anxious and healthy adolescents and adults following conditioning and extinction, processes requiring threat-safety learning. Method Anxious and healthy adolescents and adults (n=114) completed fear conditioning and extinction in the clinic. Conditioned stimuli (CS+) were neutral faces, paired with an aversive scream. Physiological and subjective data were acquired. Several weeks later, 82 participants viewed the CS+ and morphed images resembling the CS+ in a magnetic resonance imaging (MRI) scanner. During scanning, participants made difficult threat-safety discriminations while appraising threat and explicit memory of the CS+. Results During conditioning and extinction, anxious groups reported more fear than healthy groups, but patient groups did not differ on physiology. During imaging, both anxious adolescents and adults exhibited lower sub-genual anterior cingulate (sgACC) activation than healthy peers, specifically when appraising threat. In ventromedial prefrontal cortex (vmPFC), relative to their age-matched peer groups, anxious adults exhibited reduced activation when appraising threat, whereas anxious adolescents exhibited a U-shaped pattern of activation, with greater activation to the most extreme CS and CS−. Conclusions Two regions of the prefrontal cortex are involved in anxiety disorders. Reduced sgACC engagement is a shared feature in adult and adolescent anxiety disorders, but vmPFC dysfunction is age-specific. The unique U-shaped pattern of vmPFC activation in many anxious adolescents could reflect heightened sensitivity to threat and safety conditions. How variations in the pattern relate to later risk for adult illness remains to be determined. PMID:23929092

Although home Internet access has continued to increase, little is known about actual usage patterns in homes. This nationally representative study of over 4,700 Italian households with children measured computer and Internet use of each family member across 3 months. Data on actual computer and Internet usage were collected by Nielsen//NetRatings service and provide national baseline information on several variables for several age groups separately, including children, adolescents, and adult men and women. National averages are shown for the average amount of time spent using computers and on the Web, the percentage of each age group online, and the types of Web sites viewed. Overall, about one-third of children ages 2 to 11, three-fourths of adolescents and adult women, and over four-fifths of adult men access the Internet each month. Children spend an average of 22 hours/month on the computer, with a jump to 87 hours/month for adolescents. Adult women spend less time (about 60 hours/month), and adult men spend more (over 100). The types of Web sites visited are reported, including the top five for each age group. In general, search engines and Web portals are the top sites visited, regardless of age group. These data provide a baseline for comparisons across time and cultures.

Acne vulgaris is a visible skin disease commonly seen in adolescence. As it affects the appearance, it is likely to bring stress to the adolescent's life regarding sensitivity about their appearance. The aim of the study was to investigate the social anxiety level, acne-specific life quality, and self-esteem among adolescents with acne vulgaris. In addition, we evaluated the relationship between these parameters, clinical severity, and sociodemographic data. One hundred and two adolescents with acne vulgaris, aged 12-17 years without any psychiatric or medical comorbidity were recruited. The control group consisted of 83 adolescents in the same age range, who had neither psychiatric disease nor acne. Sociodemographic form (SDF), Capa Social Phobia Scale for Children and Adolescents (CSPSCA), and Rosenberg Self-esteem Scale (RSES) were applied to both groups. Additionally, the severity of acne was determined with Global Acne Grading System (GAGS), and life quality of the patients was evaluated with Acne Quality of Life Scale (AQOL). There was no significant difference in social anxiety levels and self-esteem between the study and control groups. Life quality impairment and high social anxiety levels, as well as low self-esteem, were found to be associated regardless of the clinical severity. Clinicians should be aware of the psychiatric comorbidities when treating adolescents with acne vulgaris. Especially, low self-esteem and life quality impairment should warn clinicians to predict high social anxiety levels in adolescent acne patients.

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

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

Aggressive Delinquency among North American Indigenous Adolescents: Trajectories and Predictors

Aggressive delinquency is a salient social problem for many North American Indigenous (American Indian, Canadian First Nations) communities, and can have deleterious consequences later in life. Yet there is a paucity of research on Indigenous delinquency. Group-based trajectory modeling is used to prospectively examine trajectories of aggressive delinquency over the course of adolescence using data from 646 Indigenous adolescents from a single culture, spanning the ages of 10 to 19. Five aggression trajectory groups were identified, characterized by different levels and ages of onset and desistence: non-offenders (22.1%), moderate desistors (19.9%), adolescent-limited offenders (22.2%), high desistors (16.7%), and chronic offenders (19.2%). Using the social development model of antisocial behavior, we selected relevant risk and protective factors predicted to discriminate among those most and least likely to engage in more aggressive behavior. Higher levels of risk (i.e., parent rejection, delinquent peers, substance use, and early dating) in early adolescence were associated with being in the two groups with the highest levels of aggressive delinquency. Positive school adjustment, the only significant protective factor, was associated with being in the lowest aggression trajectory groups. The results provide important information that could be used in developing prevention and intervention programs, particularly regarding vulnerable ages as well as malleable risk factors. Identifying those youth most at risk of engaging in higher levels of aggression may be key to preventing delinquency and reducing the overrepresentation of Indigenous youth in the justice system.

Five aggression trajectory groups were identified, characterized by different levels and ages of onset and desistence: non-offenders (22.1%), moderate desistors (19.9%), adolescent-limited offenders (22.2%), high desistors (16.7%), and chronic offenders (19.2%). Using the social development model of antisocial behavior, we selected relevant risk and protective factors predicted to discriminate among those most and least likely to engage in more aggressive behavior. Higher levels of risk (i.e., parent rejection, delinquent peers, substance use, and early dating) in early adolescence were associated with being in the two groups with the highest levels of aggressive delinquency. Positive school adjustment, the only significant protective factor, was associated with being in the lowest aggression trajectory groups. The results provide important information that could be used in developing prevention and intervention programs, particularly regarding vulnerable ages as well as malleable risk factors. Identifying those youth most at risk of engaging in higher levels of aggression may be key to preventing delinquency and reducing the over-representation of Indigenous youth in the justice system. © 2015 Wiley Periodicals, Inc.

Burggraaf, Rudolf; Frens, Maarten A; Hooge, Ignace T C; van der Geest, Jos N

2016-01-01

Tests measuring visuospatial abilities have shown that these abilities increase during adolescence. Unfortunately, the Block Design test and other such tests are complicated and time-consuming to administer, making them unsuitable for use with large groups of restless adolescents. The results of the Design Organization Test (DOT), a quick pen-and-paper test, have been shown to correlate with those of the Block Design test. A group of 198 healthy adolescents (110 male and 88 female) aged 12 to 19 years old participated in this study. A slightly modified version of the DOT has been used in which we shortened the administration time to avoid a ceiling effect in the score. Scores show a linear increase with age (on average 2.0 points per year, r = .61) independent of sex. Scores did not differ between individual setting and group setting. Thus, the DOT is a simple and effective way to assess visuospatial ability in large groups, such as in schools, and it can be easily administered year after year to follow the development of students.

Ego identity of adolescent children of alcoholics.

PubMed

Gavriel-Fried, Belle; Teichman, Meir

2007-01-01

The study examines the issue of ego identity among adolescent sons of alcoholic fathers. Forty-four adolescent sons of alcoholic fathers, age of 15-18, constituted the sample. They were drawn from public alcohol treatment center in Israel. The control group included 60 adolescents none of their parents is known as an alcoholic, sampled from integrative schools in the same neighborhood and matched by age. Ego identity was measured by Tzuriel's "Adolescent Ego Identity Scale" (AEIS). It was hypothesized that adolescent children of alcoholics will show lower scores of ego identity and of its dimensions. The hypothesis was not confirmed. To the contrary, adolescent children of alcoholics reported higher scores of "ego identity-total" and of four of the seven ego identity dimensions. One possible explanation is that children of alcoholics are maturing early in age compared to their controls. They have developed different coping strategies that facilitate creating a more "stable" ego identity compared to their peers. Another explanation is that children of alcoholics apply defense mechanisms that enhance the development of an "adaptive self."

This work aims to study self-esteem in adolescents with diabetes, asthma and epilepsy; compare the results with those of the representative sample of healthy adolescents; and evaluate the predictive value of certain demographic, family-related, and disease-related factors on self-esteem. A total of 148 chronically ill adolescents and 301 matched healthy counterparts completed the Rosenberg Self Esteem Scale and the "I think I am" questionnaire. Adolescents' parents answered socio-economic status questions. Disease severity was evaluated by doctors of the outpatient clinic. Comparison analysis of the three disease groups revealed highest self-esteem perception in adolescents with diabetes, and lowest in adolescents with epilepsy. Unexpectedly, adolescents with diabetes scored higher than their healthy counterparts. There were no significant differences between the reports of adolescents with asthma and controls. In the epilepsy group, self-esteem was predicted mostly by disease severity and socio-economic status in diabetes and asthma groups, as well as by age and gender. The maintenance of positive self-esteem in adolescents with diabetes and asthma is a very reassuring finding. The other results of our study provide support for recognizing adolescents with epilepsy as a vulnerable group in the society. A multidisciplinary professional approach targeted on adolescents with epilepsy is needed, with focus on factors connected with maturation and gender issues.

High adiposity and high body mass index–for-age in US children and adolescents overall and by race-ethnic group123

Background: Body mass index (BMI)–for-age has been recommended as a screening test for excess adiposity in children and adolescents. Objective: We quantified the performance of standard categories of BMI-for-age relative to the population prevalence of high adiposity in children and adolescents overall and by race-ethnic group in a nationally representative US population sample by using definitions of high adiposity that are consistent with expert committee recommendations. Design: Percentage body fat in 8821 children and adolescents aged 8–19 y was measured by using dual-energy X-ray absorptiometry in 1999–2004 as part of a health examination survey. Results: With the use of several different cutoffs for percentage fat to define high adiposity, most children with high BMI-for-age (≥95th percentile of the growth charts) had high adiposity, and few children with normal BMI-for-age (<85th percentile) had high adiposity. The prevalence of high adiposity in intermediate BMI categories varied from 45% to 15% depending on the cutoff. The prevalence of a high BMI was significantly higher in non-Hispanic black girls than in non-Hispanic white girls, but the prevalence of high adiposity was not significantly different. Conclusions: Current BMI cutoffs can identify a high prevalence of high adiposity in children with high BMI-for-age and a low prevalence of high adiposity in children with normal BMI-for-age. By these adiposity measures, less than one-half of children with intermediate BMIs-for-age (85th to <95th percentile) have high adiposity. Differences in high BMI ranges between race-ethnic groups do not necessarily indicate differences in high adiposity. PMID:20164313

The objective of this study was to compare the effect of virtual reality to passive distraction and standard care on burn treatment pain in adolescents.This single-blinded, randomized controlled study enrolled 30 adolescents who were 10 to 17 years of age from the burn clinic of a large children's hospital. After providing informed consent/assent, these participants were randomly assigned to one of three groups during wound care: standard care, passive distraction watching a movie, or virtual reality (VR) using a tripod-arm device rather than an immersive helmet. Before wound care, participants completed the Spielberger's State-Trait Anxiety Inventory for Children and Pre-Procedure Questionnaire while blinded to group assignment. A total of 28 participants completed the study and rated treatment pain after wound care by using the Adolescent Pediatric Pain Tool and completed a Post-Procedure Questionnaire. The VR group reported less pain during wound care than either the passive distraction or standard care group as determined by multivariable linear regression adjusted for age, sex, preprocedure pain, state anxiety, opiate use, and treatment length. The VR group was the only group to have an estimated decrease in pain perception from baseline preprocedure pain to procedural pain reported. Adolescents pretreated with opiate analgesics and female adolescents reported more pain during wound care.This between-subjects clinical study provides further support for VR, even without requiring wearing of an immersive helmet, in lessening burn wound care pain in adolescents. Passive distraction by watching a movie may be less effective in reducing treatment pain. Additional between-subjects randomized controlled trials with larger samples of children and during other healthcare treatments may further support VR's effectiveness in pediatric procedural pain management.

2007-01-01

Background Recent reports have suggested a rotational strength weakness in rotations to the concave side in patients with idiopathic scoliosis. There have been no studies presenting normative values of female adolescent trunk rotational strength to which a comparison of female adolescents with idiopathic scoliosis could be made. The purpose of this study was to determine trunk rotational strength asymmetry in a group of female adolescents with AIS and a comparison group of healthy female adolescents without scoliosis. Methods Twenty-six healthy adolescent females served as the healthy group (HG) (average age 14 years) and fourteen otherwise healthy adolescent females with idiopathic scoliosis served as the idiopathic scoliosis group (ISG) (average age 13.5 years, average Cobb 28°). Participant's isometric trunk rotational strength was measured in five randomly ordered trunk positions: neutral, 18° and 36° of right and left pre-rotation. Rotational strength asymmetry was compared within each group and between the two groups using several different measures. Results The HG showed strength asymmetry in the 36° pre-rotated trunk positions when rotating towards the midline (p < 0.05). The ISG showed strength asymmetry when rotating towards the concavity of their primary curve from the neutral position (p < 0.05) and when rotating towards the concavity from the 18° (p < 0.05) and 36° (p < 0.05) concave pre-rotated positions. The ISG is significantly weaker than the HG when rotating away from the midline toward the concave (ISG)-left (HG) side from the concave/left pre-rotated 18° (p < 0.05) and 36° (p < 0.05) positions. Conclusion The AIS females were found to be significantly weaker when contracting toward their main curve concavity in the neutral and concave pre-rotated positions compared to contractions toward the convexity. These weaknesses were also demonstrated when compared to the group of healthy female adolescent controls. Possible mechanisms for the strength asymmetry in ISG are discussed. PMID:17620141

Introduction and Hypothesis Anal sphincter tears during vaginal delivery may result in serious sequelae. We examined whether younger primiparous patients were at increased risk for sphincter tears during vaginal delivery. Methods Data from an obstetric automated record were analyzed. Primiparous women delivering term infants (n = 5,937) were included to test for an association between age and sphincter tear rates. Three age groups were considered: young adolescents (≤16 years), older adolescents (17-20 years) and adults (≥21 years). Results No significant difference was found in tear rates among age cohorts (9.2%, 8.0%, and 9.6% respectively; p = 0.12). Logistic regression modeling revealed that young adolescents were not more likely to have sphincter tears compared to older cohorts. Conclusions Younger adolescents may not be at increased risk of anal sphincter tears. Decisions regarding interventions to decrease sphincter tears during vaginal delivery should not be made on the basis of maternal age alone. PMID:18985267

To analyze motivation, food self-administration and decision-making were evaluated in adolescent, adult, and aged rats. Subjects were trained to press a lever (fixed ratio, FR1 and FR5) in an operant chamber, to obtain chocolate flavor pellets. They assessed the progressive ratio (PR), extinction, and reinstatement of the behavior. To estimate decision-making for food, rats were trained in the conditioned place preference (CPP) paradigm: (a) associating one compartment with lab chow (LCh) one day and the other compartment with rice krisspies (RK), the next day. (b) Training similar to (a) but on the day RK was the reinforcer, it was delivered with a progressive delay. In addition, CB1 and CB2 receptor expression in the nucleus accumbens (NAcc) and prefrontal cortex (PFC) was estimated by means of Western blot. Adolescent rats consumed higher amounts of RK/body weight than adult and aged rats during FR1, FR5, and PR. Extinction was more prolonged for adolescent rats than for adult and aged rats. First CPP condition, all three groups of rats preferred the RK-associated compartment. Second CPP condition, adolescent rats developed equal preference to both compartments, while adult and aged rats preferred the RK-associated compartment. Rats per group ate a similar amount of either reinforcer. Adolescent rats exhibited low expression of CB1R in the NAcc and low expression of both CB1R and CB2R in the PFC compared with adult and aged rats. Adolescent rats display higher motivation for palatable food and an indiscriminate seeking behavior suggesting involvement of both homeostatic and hedonic systems in their decision-making processes. © 2016 Wiley Periodicals, Inc.

To examine the association between breakfast skipping and physical activity among US adolescents aged 12-19 years. A cross-sectional study of nationally representative 2007-2008 National Health and Nutrition Examination Survey (NHANES) data. Breakfast skipping was assessed by two 24 h dietary recalls. Physical activity was self-reported by participants and classified based on meeting national recommendations for physical activity for the appropriate age group. Multiple logistic regression analysis was used to model the association between breakfast skipping and physical activity while controlling for confounders. A total of 936 adolescents aged 12-19 years in the USA. After adjusting for family income, there was no association between breakfast skipping and meeting physical activity guidelines for age among adolescents aged 12-19 years (OR = 0.95, 95% CI 0.56, 1.32). Findings from the study differ from previous research findings on breakfast skipping and physical activity. Therefore, further research that uses large, nationally representative US samples and national recommended guidelines for physical activity is needed.

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

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

2018-01-01

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

Proper scapulothoracic and hip mechanics are essential aspects of the throwing kinetic chain. Little is known regarding these entities in preadolescent and adolescent baseball players. Scapular malposition and dyskinesis as well as hip dysfunction are highly prevalent in preadolescent and adolescent baseball players and may be identified by simple clinical testing. Descriptive laboratory study. A total of 112 baseball players aged 7 to 18 years were recruited from local Little Leagues, traveling teams, and high schools. Participants were divided into 2 groups: preadolescents (players aged 7-12 years) and adolescents (players aged 13-18 years). Scapular symmetry was tested with the yes/no method of Kibler and by measuring forward shoulder posture via the "coracoid distance." Hip abductor strength was measured by use of a handheld digital dynamometer. Functional gluteal and core strength was assessed by video analysis of the subjects performing the single-legged squat test. Hip range of motion was measured in the prone position by use of a handheld goniometer. Compared with the preadolescent group, the adolescent group had a significantly higher prevalence of scapular dyskinesis in the throwing shoulder (50% vs 25.9%, P = .011). The adolescents had significantly higher normalized hip abduction strength in both the stride (17.41 vs 12.62 N/kg, P < .001) and stance (17.82 vs 12.61 N/kg, P < .001) legs. The preadolescent group was unable to perform the single-legged squat test correctly in either the stance (0% preadolescent vs 13% adolescent, P = .0127) or stride (0% preadolescent vs 9.3% adolescent, P = .0567) leg. The mean coracoid distance was elevated in the dominant (throwing) shoulder after controlling for scapular dyskinesis (P < .0001). Presence of scapular dyskinesis was associated with a higher mean coracoid distance (P = .0067). There was a high prevalence of dominant shoulder scapular dyskinesis in the adolescent compared with the preadolescent group, as well as universally poor single-legged squat test performance. The mean coracoid distance was higher in the dominant or throwing side compared with the nondominant side independent of scapular dyskinesis. Presence of scapular dyskinesis was associated with higher mean coracoid distance. Identification of players thought to be at increased risk for throwing injuries and initiation of targeted rehabilitation programs may decrease injury rates in preadolescent and adolescent baseball players. © 2014 The Author(s).

The Relationship Between Mindfulness, Depressive Symptoms, and Non-Suicidal Self-Injury Amongst Adolescents.

2016-01-01

Mindfulness is often part of treatment for non-suicidal self-injury (NSSI); however, there has been limited research examining the role of mindfulness in NSSI. Thus, the current study sought to investigate the relationship among mindfulness, depressive symptoms, and NSSI (past year) in adolescents (N = 764; 56.8% female, M age = 14.42, SD = 0.64) with consideration of gender. Adolescents with recent NSSI (n = 74; 83.8% female, M age = 14.36, SD = 0.56) and a matched for age and gender no-NSSI group completed measures of mindfulness and depression. Findings revealed that mindfulness and depressive symptoms were negatively correlated, although significantly less so for the NSSI group. Second, the NSSI group reported greater depressive symptoms and less mindfulness. Finally, mindfulness was found to partially mediate the effect of depressive symptoms on NSSI. The present study is the first to provide empirical support for the protective role of mindfulness in NSSI.

Individual heterogeneity exists in the onset and development of conduct problems, but theoretical claims about predictors and prognosis are often not consistent with the empirical findings. This study examined shape and outcomes of conduct problem trajectories in a Belgian population-based sample (N = 682; 49.5 % boys). Mothers reported on children's conduct problems across six waves (age 4-17) and emerging adults reported on their behavioral adjustment (age 17-20). Applying mixture modeling, we found four gender-invariant trajectories (labeled life-course-persistent, adolescence-onset, childhood-limited, and low). The life-course-persistent group was least favorably adjusted, but the adolescence-onset group was similarly maladjusted in externalizing problems and may be less normative (15 % of the sample) than previously believed. The childhood-limited group was at heightened risk for specifically internalizing problems, being more worrisome than its label suggests. Interventions should not only be aimed at early detection of conduct problems, but also at adolescents to avoid future maladjustment.

Sexual orientation and alcohol problem use among U.K. adolescents: an indirect link through depressed mood.

Sexual minority adolescents are more likely to engage in alcohol use than their heterosexual counterparts; however, the underlying reasons remain unclear and longitudinal research is limited. Owing to evidence that this group also experiences greater depressive symptoms than their peers, we aimed to (i) assess to what extent depressed mood explains the increased likelihood of engaging in alcohol use among sexual minority adolescents, and (ii) explore potential gender-specific patterns. Structural equation modelling was used to test the indirect relationship between sexual orientation and alcohol use through depressed mood, with heterosexuals as the reference group. A total of 3710 adolescents (12% sexual minority), from the Avon Longitudinal Study of Parents and Children (ALSPAC) study, assessed between the ages of 15 and 18 years. Sexual orientation was assessed at age 15, while alcohol use was measured using the Alcohol Use Disorders Identification Test (AUDIT) at age 18. Depressed mood was indexed by the Short Mood and Feelings Questionnaire (SMFQ) at age 16. Sexual minority adolescents were more likely to engage in alcohol problem use compared to their heterosexual counterparts [Btotal  = 0.12, 95% confidence interval (CI) = 0.04-0.20, P = 0.003]. Depressed mood explained 21% of the link between sexual orientation and alcohol use after adjustment for covariates and earlier measures (Z = 3.2, P = 0.001). No gender differences were observed. A higher prevalence of alcohol problem use in adolescents who are gay, lesbian or bisexual is partly explained by increased rates of depression in this group. © 2014 Society for the Study of Addiction.

Childhood- versus adolescent-onset antisocial youth with conduct disorder: psychiatric illness, neuropsychological and psychosocial function.

The present study investigates whether youths with childhood-onset antisocial behavior have higher rates of psychiatric illness, neuropsychological and psychosocial dysfunction than youths who engage in antisocial behavior for the first time in adolescence. Prior studies have generally focused on single domains of function in heterogeneous samples. The present study also examined the extent to which adolescent-onset antisocial behavior can be considered normative, an assumption of Moffitt's dual taxonomy model. Forty-three subjects (34 males, 9 females, mean age = 15.31, age range 12-21) with a diagnosis of conduct disorder (CD) were recruited through Headspace Services and the Juvenile Justice Community Centre. We compared childhood-onset antisocial youths (n = 23) with adolescent-onset antisocial youths (n = 20) with a conduct disorder, across a battery of psychiatric, neuropsychological and psychosocial measures. Neuropsychological function of both groups was also compared with normative scores from control samples. The childhood-onset group displayed deficits in verbal learning and memory, higher rates of psychosis, childhood maltreatment and more serious violent behavior, all effects associated with a large effect size. Both groups had impaired executive function, falling within the extremely low range (severely impaired). Childhood-onset CD displayed greater cognitive impairment, more psychiatric symptoms and committed more serious violent offences. The finding of severe executive impairment in both childhood- and adolescent-onset groupings challenges the assumption that adolescent-onset antisocial behavior is a normative process.

The present study examined whether the cross-sectional association between body dissatisfaction and low self-esteem varies across gender, age, body weight status, race/ethnicity, and socioeconomic status (SES). We also examined the association longitudinally. A school-based survey of eating, weight, and related attitudes was conducted with a diverse sample of adolescents aged 11-18 years (N = 4,746). Height and weight were measured in the schools at Time 1. Participants were resurveyed through mails 5 years later (Time, 2; N = 2,516). The relationship between body dissatisfaction and self-esteem was strong and significant in both boys and girls (all p values < .0001), and did not differ significantly between genders (p = .16), or between the middle school and high school cohorts in either boys (p = .79) or girls (p = .80). Among girls, the relationship between body dissatisfaction and self-esteem was strong, but did vary across weight status, race/ethnicity, and SES (all p values = .0001-.03). The relationship was nonsignificant in underweight girls (p = .36), and weaker but still significant among black, Asian, and low SES group girls (all p values < .0001) in comparison to white and high SES group girls. Among boys, the association did not differ significantly across demographic groups (all p values = .18-.79). In longitudinal analyses, the strength of the association did not change significantly as adolescents grew older. Findings indicate that body dissatisfaction and self-esteem are strongly related among nearly all groups of adolescents. This suggests the importance of addressing body image concerns with adolescents of all backgrounds and ages.

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

Objectives Rates of pregnancy and HIV infection are high among South African adolescents, yet little is known about rates of mother-to-child transmission of HIV (MTCT) in this group. We report a comparison of the characteristics of adolescent mothers and adult mothers, including HIV prevalence and MTCT rates. Methods We examined patterns of health service utilization during the antenatal and early postnatal period, HIV prevalence and MTCT amongst adolescent (<20-years-old) and adult (20 to 39-years-old) mothers with infants aged ≤16 weeks attending immunization clinics in six districts of KwaZulu-Natal between May 2008 and April 2009. Findings Interviews were conducted with 19,093 mothers aged between 12 and 39 years whose infants were aged ≤16 weeks. Most mothers had attended antenatal care four or more times during their last pregnancy (80.3%), and reported having an HIV test (98.2%). A greater proportion of HIV-infected adult mothers, compared to adolescent mothers, reported themselves as HIV-positive (41.2% vs. 15.9%, p<0.0001), reported having a CD4 count taken during their pregnancy (81.0% vs. 66.5%, p<0.0001), and having received the CD4 count result (84.4% vs. 75.7%, p<0.0001). Significantly fewer adolescent mothers received the recommended PMTCT regimen. HIV antibody was detected in 40.4% of 7,800 infants aged 4–8 weeks tested for HIV, indicating HIV exposure. This was higher among infants of adult mothers (47.4%) compared to adolescent mothers (17.9%, p<0.0001). The MTCT rate at 4–8 weeks of age was significantly higher amongst infants of adolescent mothers compared to adult mothers (35/325 [10.8%] vs. 185/2,800 [6.1%], OR 1.7, 95% CI 1.2–2.4). Conclusion Despite high levels of antenatal clinic attendance among pregnant adolescents in KwaZulu-Natal, the MTCT risk is higher among infants of HIV-infected adolescent mothers compared to adult mothers. Access to adolescent-friendly family planning and PMTCT services should be prioritised for this vulnerable group. PMID:24073215

Findings on face identity and facial emotion recognition in autism spectrum disorder (ASD) are inconclusive. Moreover, little is known about the developmental trajectory of face processing skills in ASD. Taking a developmental perspective, the aim of this study was to extend previous findings on face processing skills in a sample of adolescents and adults with ASD. N = 38 adolescents and adults (13-49 years) with high-functioning ASD and n = 37 typically developing (TD) control subjects matched for age and IQ participated in the study. Moreover, n = 18 TD children between the ages of 8 and 12 were included to address the question whether face processing skills in ASD follow a delayed developmental pattern. Face processing skills were assessed using computerized tasks of face identity recognition (FR) and identification of facial emotions (IFE). ASD subjects showed impaired performance on several parameters of the FR and IFE task compared to TD control adolescents and adults. Whereas TD adolescents and adults outperformed TD children in both tasks, performance in ASD adolescents and adults was similar to the group of TD children. Within the groups of ASD and control adolescents and adults, no age-related changes in performance were found. Our findings corroborate and extend previous studies showing that ASD is characterised by broad impairments in the ability to process faces. These impairments seem to reflect a developmentally delayed pattern that remains stable throughout adolescence and adulthood.

This study examined trends in iron status in adolescents. Serum ferritin was measured in 1986 and 1992 in 319 Danes (161 males) stratified into 5 groups: I. median age 9 yr in 1986 vs. 15 yr in 1992; II. 11 vs. 17 yr; III. 13 vs. 19 yr; IV. 15 vs. 21 yr; V. 17 vs. 23 yr. Males in group I demonstrated no change in ferritin or estimated iron stores in mg/kg; groups II-V displayed an increase in iron status parameters. All groups showed an increase in estimated total iron stores. Changes in iron status parameters were inversely correlated with height velocity in group III, and positively correlated with height velocity in group V. Females in age groups I and II demonstrated a fall in ferritin and estimated iron stores in mg/kg in association with menarche; values were unchanged in groups III and IV, and increased in group V. All groups showed an increase in estimated total iron stores. Changes in iron status parameters were inversely correlated with height velocity in groups I and II. In conclusion, ferritin levels in adolescents display great variation during growth spurt and at menarche. Changes in ferritin showed no consistent association with growth velocity. In both genders, estimated total iron stores increased with age.

Failure to distinguish bipolar depression (BDd) from the unipolar depression of major depressive disorder (UDd) in adolescents has significant clinical consequences. We aimed to identify differential patterns of functional neural activity in BDd versus UDd and employed two (fearful and happy) facial expression/ gender labeling functional magnetic resonance imaging (fMRI) experiments to study emotion processing in 10 BDd (8 females, mean age=15.1 ± 1.1) compared to age- and gender-matched 10 UDd and 10 healthy control (HC) adolescents who were age- and gender-matched to the BDd group. BDd adolescents, relative to UDd, showed significantly lower activity to both intense happy (e.g., insula and temporal cortex) and intense fearful faces (e.g., frontal precentral cortex). Although the neural regions recruited in each group were not the same, both BDd and UDd adolescents, relative to HC, showed significantly lower neural activity to intense happy and mild happy faces, but elevated neural activity to mild fearful faces. Our results indicated that patterns of neural activity to intense positive and negative emotional stimuli can help differentiate BDd from UDd in adolescents. Copyright © 2013 Elsevier Ireland Ltd.

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

The authors investigated the intergroup processes of male adolescents within the context of social identity theory (SIT; H. Tajfel, 1978; H. Tajfel & J. C. Turner, 1979). The participants were English male adolescents (age = 14-15 years). They estimated in-group and out-group musical preferences and evaluated the in-group and out-group along a series of scales. The results showed in-group favoritism effects along the musical preference and evaluative dimensions. The participants reported greater liking for the in-group. Compared with the out-group, they associated the in-group more with positively stereotyped music and less with negatively stereotyped music. Compared with the out-group, they rated the in-group as more fun, more masculine, more sporty, less boring, less snobbish, and less weird. The participants with lower levels of self-esteem showed greater differentiation between groups and greater derogation of the out-group. The results supported the predictions of SIT and demonstrated the applicability of SIT for the study of adolescent behavior.

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

Paroxysmal nonepileptic events (PNEs) are frequently encountered phenomena in children. Although frequencies and types of PNEs have been extensively studied in adult populations, the data available for children and adolescents are limited, especially in patients without underlying neurologic disorders. In this study, we evaluated and compared the characteristics of PNEs between age groups and according to the presence of neurologic deficits to improve early detection and diagnosis of PNEs. We retrospectively reviewed 887 pediatric patients who were admitted to the epilepsy monitoring unit at the Samsung Medical Center between December 2001 and July 2014. One hundred and forty-one patients (15.9%) were diagnosed as having PNEs on the basis of their clinical history and long-term video-electroencephalography (EEG) monitoring (VEM). Children with PNEs were divided into three groups by age: 1) the infant, toddler, and preschool group (<6 years, N=50, 35.5%); 2) the school-age group (6-<12 years, N=30, 21.3%); and 3) the adolescent group (12-<18 years, N=61, 43.3%). Physiologic disorders, such as normal infant behavior, sleep movement, and staring, were more common in patients younger than 6 years of age, whereas psychogenic nonepileptic seizures were predominant in patients older than 6 years. Vasogenic syncope was also frequently observed in the adolescent group and was confirmed by the head-up tilt test. There was no significant difference in specific PNE types between the groups of patients with or without neurologic deficits. Physiologic symptoms were predominant in the younger age group, whereas psychogenic nonepileptic seizures were observed in older age groups more often. Clinical pattern recognition by age plays an important role in clinical practice, because pediatric patients present various types of PNEs with age-specific patterns. Considering various and inconsistent presentations and the importance of correct diagnosis, long-term VEM can be helpful in diagnosing normal infant behavior and psychogenic nonepileptic seizures.

2018-04-01

This cross-sectional study examined 6 key areas of neuropsychological functioning (cognitive, academic, attention, executive function, adaptive skills) comparing adolescents and school-age children with prenatal alcohol exposure (PAE). The aims were: (i) to examine which neuropsychological measures were predictive of an FASD diagnosis in adolescents and school-age children with PAE, and (ii) to compare the neuropsychological performance of adolescents and children diagnosed with FASD. Hierarchical logistic regressions determined that the Full-Scale IQ, Verbal Comprehension and Perceptual Reasoning indices, basic reading and math skills, adaptive functioning at school, and components of executive functioning (dependent on age) improved the probability of an accurate FASD diagnosis in both groups: 9.1% to 19.2% for adolescents and 10.9% to 19.4% for school-age children (61.5%-80.9% correct classifications overall). For the age comparison analyses (ANOVAs/MANOVAs), a significant difference was observed in the cognitive domain, as well as with basic math skills (trend) in the sample diagnosed with FASD, with lower scores observed for adolescents across these measures. These findings provide further evidence for age differences in neuropsychological assessment as well as increased neuropsychological difficulties in adolescence by comparison with childhood with FASD. Longitudinal studies will be needed to make further inferences about developmental changes in neuropsychological functioning in FASD.

Several studies have reported that physical inactivity and sedentary lifestyle are associated with being overweight and obese in children and adults. A new policy of 1-h physical activity (PA) every day was released by the Chinese government. The present study examined the role of 1-h PA every day in preventing obesity in adolescents in Shandong, China. A total of 29,030 students (14,578 boys and 14,452 girls) aged 10-18 years participated in this study. Height, weight, waist circumference (WC), and skinfold thickness (SFT) of all subjects were measured; body mass index (BMI) of adolescents was calculated from their height and weight, and the prevalence of overweight and obesity was obtained according to the International Obesity Task Force cutoffs. All subjects were divided into two groups. Group 1 had a PA of more than 1 h/day while group 2 had less than 1 h/day. Comparisons of BMI, WC, SFT, and prevalences of overweight and obesity between the two groups were made. The overall percentages of students in group 1 were 34.29 % in boys and 30.15 % in girls. The prevalences of overweight and obesity for both boys and girls were all significantly lower in group 1 than in group 2 in all age categories. In conclusion, 1-h PA every day has a beneficial effect in preventing obesity in adolescents in Shandong, China. These observations highlight the importance of PA in the prevention of overweight and obesity in adolescents.

The potential neurochemical toxicity associated with methamphetamine (MA) or marijuana (MJ) use on the developing adolescent brain is unclear, particularly with regard to individuals with concomitant use of MA and MJ (MA+MJ). In this study, proton magnetic resonance spectroscopy (MRS) was utilized to measure in vivo brain N-acetylaspartate plus N-acetylaspartyl glutamate (tNAA, an indicator of intact neuronal integrity) levels. Three adolescent groups from Cape Town, South Africa completed MRS scans as well as clinical measures including a drug use history. Subjects included (1) nine MA (age=15.7±1.37), (2) eight MA+MJ (age=16.2±1.16) using adolescents and (3) ten healthy controls (age=16.8±0.62). Single voxel spectra were acquired from midfrontal gray matter using a point-resolved spectroscopy sequence (PRESS). The MRS data were post-processed in the fully automated approach for quantitation of metabolite ratios to phosphocreatine plus creatine (PCr+Cr). A significant reduction in frontal tNAA/PCr+Cr ratios was seen in the MA+MJ group compared to the healthy controls (p=0.01, by 7.2%) and to the MA group (p=0.04, by 6.9%). Significant relationships were also observed between decreased tNAA/PCr+Cr ratios and drug use history of MA or MJ (total cumulative lifetime dose, age of onset, and duration of MA and MJ exposure) only in the MA+MJ group (all p<0.05). These findings suggest that in adolescents, concomitant heavy MA+MJ use may contribute to altered brain metabolites in frontal gray matter. The significant associations between the abnormal tNAA/PCr+Cr ratios and the drug use history suggest that MA+MJ abuse may induce neurotoxicity in a dose-responsive manner in adolescent brain.

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

Longitudinal survey data of stature and body weight from age 7 to 17 were obtained for 100 boys and 100 girls during World War II. The growth rates and the average annual increments were compared with those of children born after the war. Growth attained at age 7 as a percentage of that at age 17 is larger in children of the control group, presumably as a result of an improved environment affecting the growth increment. The age at maximum velocity is six months to one year earlier for the current group of children. Although the maximum velocities for both items and sexes are nearly the same in the groups compared, the total increments are larger in the current group of children. Age, distance, and maximum velocity at adolescent growth spurt were obtained for each child. The mean values were compared according to growth patterns and growth attained at age 7. The "increasing type" growth group has the highest velocity at the greatest distance and the oldest age for stature. Children who were taller or heavier at age 7 have velocity peaks with greater distances.

Evaluate the relationship between body mass index and physical fitness in a cross-sectional sample of Brazilian youth. Participants were 3849 adolescents (2027 girls) aged 10-17 years. Weight and height were measured; body mass index was calculated. Physical fitness was evaluated with a multistage 20m shuttle run (cardiovascular endurance), standing long jump (power), and push-ups (upper body strength). Participants were grouped by sex into four age groups: 10-11, 12-13, 14-15, and 16-17 years. Sex-specific ANOVA was used to evaluate differences in each physical fitness item among weight status categories by age group. Relationships between body mass index and each physical fitness item were evaluated with quadratic regression models by age group within each sex. The physical fitness of thin and normal youth was, with few exceptions, significantly better than the physical fitness of overweight and obese youth in each age group by sex. On the other hand, physical fitness performances did not consistently differ, on average, between thin and normal weight and between overweight and obese youths. Results of the quadratic regressions indicated a curvilinear (parabolic) relationship between body mass index and each physical fitness item in most age groups. Better performances were attained by adolescents in the mid-range of the body mass index distribution, while performances of youth at the low and high ends of the body mass index distribution were lower. Relationships between the body mass index and physical fitness were generally nonlinear (parabolic) in youth 10-17 years. Copyright © 2018 Sociedade Brasileira de Pediatria.

Explore psychological functioning in adolescents with a cleft at age 16 from a broad perspective, including cognitive, emotional, behavioral, appearance-related, and psychosocial adjustment. High-risk groups were identified within each area of adjustment to investigate whether vulnerable adolescents were found across domains or whether risk was limited to specific areas of adjustment. Cross-sectional data based on psychological assessments at age 16 (N = 857). The effect of gender, cleft visibility, and the presence of an additional condition were investigated on all outcome variables. Results were compared with large national samples. Hopkins Symptom Checklist, Harter Self-Perception Scale for Adolescents, Child Experience Questionnaire, and Satisfaction With Appearance scale. The main factor influencing psychological adjustment across domains was gender, with girls in general reporting more psychological problems, as seen in reference groups. The presence of an additional condition also negatively affected some of the measures. No support was found for cleft visibility as a risk factor except for dissatisfaction with appearance. Correlation analyses of risk groups seem to point to an association between social and emotional risk and between social risk and dissatisfaction with appearance. Associations between other domains were found to be weak. The results point to areas of both risk and strength in adolescents born with a cleft lip and/or palate. Future research should investigate how protective factors could counteract potential risk in adolescents with a cleft.

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.

2016-12-01

An initial field study to investigate dental caries and dental erosion in children and adolescents in the community of Soroti, Uganda. A stratified two-stage cluster sample of 84 children (ages 8-10) and adolescents (ages 16-19) were recruited. A survey was undertaken to assess the state of determinants of oral health, oral hygiene practices, and soft-drink and sweetened-tea consumption. Intra-oral photographs were taken and reviewed to measure Decayed, Missing, and Filled Teeth (DMFT) and dental erosion. A significant difference was observed in DMFT between children and adolescents (3.7 ± 2.7 versus 2.1 ± 2.4 p=.02). A trend of lower erosion scores was seen in children compared to adolescents. Greater frequency of sweetened-tea consumption over soft-drinks was noted in both groups. This study did not reveal any relationship between different levels of cariogenic beverage consumption and DMFT or dental erosion in this sample group.

A comparative study. The aims of this study were to: (1) evaluate Scoliosis Research Society (SRS)-22 questionnaire performance in normal adolescents without scoliosis to establish a normative baseline useful for evaluating the discriminate validity of the SRS-22 in primary adolescent scoliosis; and (2) investigate impact of age and sex on SRS-22 in an adolescent population unaffected by scoliosis. The SRS-22 questionnaire is widely used to measure health-related quality of life of patients with spinal disease including scoliosis and lumbar spondylolisthesis. However, normal data, which are very important, when comparing patients and nonpatients, are few, little, and there are few studies about factors that may affect SRS questionnaire performance. The adolescent population was from 14 schools located in 7 provinces. A total of 2008 adolescents (961 females, 1026 males, 21 unknown; mean age, 14.3 yr; range, 11-20) completed the simplified Chinese version of SRS-22 questionnaire and demographic questions. Surveys were stratified into 8 age-sex groups for analysis: male/female; 12 to 13.4, 13.5 to 14.9, 15 to 15.9, and more than 16 years of age. Post hoc testing and the Tukey least significant difference were used to compare differences between any 2 of the 4 age groups. Self-image scores in males were higher than those in females (P < 0.01). Pain domain scores were significantly higher in males than those in females in the 13.5- to 14.9-year-old subgroup, whereas other subgroups showed no obvious differences. The function domain scores in males who were aged 15 to 15.9 years and those older than 16 years were significantly higher than those in females (P < 0.001). There were no statistically significant differences in mental health domain scores among age-sex subgroups, with the exception of the 13.5- to 14.9-year-old group. This is the first study to characterize the sex and age influence on the SRS-22 scores in normal population. Age and sex have an important effect on SRS-22 scores, so when using the instrument to assess health-related quality of life of patients with scoliosis or other spinal disease, we should consider the differences in patients with different age and sex. 3.

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

Objective Home oximetry is commonly used to screen for obstructive sleep apnea (OSA) in children; however, normal oxygen desaturation levels by disease severity are not well known. It was our objective to determine if oxygen saturation levels differed by OSA severity category in children and if these differences were similar for preteen children and adolescents. Study Design Retrospective case series of children undergoing polysomnography from September 2011 to July 2015. Setting Tertiary pediatric hospital. Subjects and Methods Six- to 18-year-olds (preteen, 6-12 years old; adolescent, 13-18 years old). Chi-square, Wilcoxon rank sum test, and Kruskal-Wallis testing were used to compare variables between age groups. Results The study included 342 children with a mean age of 11.3 ± 2.4 years (range, 6.5-17.5) and a mean body mass index of 25.6 ± 9.2 kg/m 2 (78 ± 29 percentile); 61% were white, 35% were black, and 4% were other or unknown. Of the children, 48% were female, and this was not a significant difference between age groups ( P = .81). Overall, 50% of the children had no OSA, 32% mild, 10% moderate, and 8% severe. When compared with the younger children, the adolescents had a longer sleep time ( P = .014) and a higher mean obstructive apnea-hypopnea index (3.53 ± 5.1 vs 3.03 ± 6.1 events per hour, P = .02). The 3% and 4% oxygen desaturation indices were not significantly different between age groups when accounting for OSA severity. Conclusion Adolescents have longer sleep times and higher obstructive apnea-hypopnea indexes than preteens, but oxygen saturations and desaturation indices were similar. This supports current triage algorithms for children with OSA, as we found no significant age-based differences.

Neurodevelopment: The Impact of Nutrition and Inflammation During Adolescence in Low-Resource Settings

Approximately 1 out of 5 children worldwide suffers from childhood malnutrition or stunting and associated health conditions, including an increased susceptibility to infections and inflammation. Due to improved early interventions, most children even in low-resource settings now survive early childhood malnutrition, yet exhibit continuing evidence of neurodevelopmental deficits, including poor school achievement and behavioral problems. These conditions are compounded in children who continue to be undernourished throughout the adolescent years. At present, these sequelae of malnutrition and infection are of major concern in the adolescent population, given that young people between the ages of 10 and 24 years represent nearly one-quarter of the world’s population. Therefore, there is an urgent need to focus on the well-being of this age group and, in particular, on behavioral, cognitive, and brain disorders of adolescents who experienced malnutrition, infection, and inflammation prenatally, in early childhood, and during adolescence itself. Because one-third of all women globally become pregnant during their adolescent years, brain and behavioral disorders during this period can have an intergenerational impact, affecting the health and well-being of the next generation. This article summarizes the current state of knowledge and evidence gaps regarding childhood and adolescent malnutrition and inflammation and their impact on adolescent neurodevelopment, the limited evidence regarding nutrition and psychosocial interventions, and the role of resilience and protective factors in this age group. This overview should help to inform the development of new strategies to improve the neurodevelopmental outcomes of high risk adolescent populations. PMID:28562250

Adolescents are an especially vulnerable age group in terms of behavioral issues and require skilled teams in health centers. To assess the quality of health services provided to teenage users in Primary Health Care. A study of multiple cases was carried out in two family health centers in Puente Alto, Chile. Health services delivered to adolescents were evaluated from the provider's perspective, through qualitative design of focus groups and interviews to the care teams at each centre. For technical quality, comparing electronic records of two tracer conditions (prenatal care and depression) with technical standards established by Delphi methodology and from teenage users perspective, through a survey of service satisfaction. In both centers, providers perceived a lack of training in adolescent care, a deficient preventive approach and a limited access to care. The technical evaluation showed an inappropriate recording of both tracer conditions. The instrument used to assess user satisfaction survey was reliable and showed that the best perceived issue was medical care and treatment, and the least perceived, was the access to the services. Professionals working in these health care facilities, feel unprepared to provide comprehensive approach to adolescents. The surveyed teenagers complained of limited access to care. Therefore this age group continues to be as a non-priority group for health care.

Although adults' aerobic fitness is known to be correlated with cardiovascular disease risk, the longitudinal relationship with adolescent aerobic fitness is poorly described. To longitudinally investigate the relationship between aerobic fitness during adolescence and adulthood. Participants (207 boys, 149 girls) aged 7-17 years performed annual measures of VO2peak. In adulthood (40 and 50 years), 78 individuals (59 males and 18 females) were reassessed. Serial height measurements were used to estimate age at peak height velocity (APHV). During adolescence, VO2peak was measured via a treadmill test to voluntary exhaustion; adult VO2peak was assessed using submaximal predictive tests. Correlations were tested using Spearman's rho. ANCOVA was used to assess adult VO2peak group differences based off APHV VO2peak groupings (low, average or high). When sexes were pooled, moderate tracking existed from 2 years prior to APHV to APHV and APHV to 2 years after APHV (0.46, p < 0.001 and 0.35, p < 0.01, respectively). Correlations between APHV and adult values were low when sexes were pooled (p < 0.05). Comparisons of aggregated sexes revealed the low adolescent VO2peak group had lower values in adulthood relative to other groups (p < 0.05). Aerobic fitness has a low tracking between APHV and adulthood.

The aim of this study was to investigate whether adolescent growth trajectories of aerobic fitness and adiposity were associated with mid-adulthood cardiometabolic risk (CMR). Participants were drawn from the Saskatchewan Growth and Development Study (1963-1973). Adolescent growth trajectories for maximal aerobic capacity (absolute VO 2 (AbsVO 2 )), skinfolds (SF), representing total body (Sum6SF) and central adiposity (TrunkSF), and body mass index (BMI) were determined from 7 to 17 years of age. In mid-adulthood (40 to 50 years of age), 61 individuals (23 females) returned for follow-ups. A CMR score was calculated to group participants as displaying either high or a low CMR. Multilevel hierarchical models were constructed, comparing the adolescent growth trajectories of AbsVO 2, Sum6SF, TrunkSF, and BMI between CMR groupings. There were no significant differences in the adolescent development of AbsVO 2, Sum6SF, TrunkSF, and BMI between adult CMR groupings ( p > 0.05). Individuals with high CMR accrued 62% greater adjusted total body fat percentage from adolescence to adulthood ( p =0.03). Growth trajectories of adolescent aerobic fitness and adiposity do not appear to be associated with mid-adulthood CMR. Individuals should be encouraged to participate in behaviours that promote healthy aerobic fitness and adiposity levels throughout life to reduce lifelong CMR.

The effect of weight gain in late adolescence on bone is not clear. Young women who consistently gained weight (n = 23) from 17 to 22 yr of age had increased BMD but a lack of subperiosteal expansion compared with stable weight peers (n = 48). Bone strength increased appropriately for lean mass in both groups but decreased relative to body weight in weight gainers, suggesting increased bone fragility in weight gainers. Introduction Weight gain leading to obesity often starts in adolescence, yet little is known about its effects on bone. We used longitudinal data to examine the effects of weight gain in late adolescence (from 17 to 22 yr of age) on proximal femur BMD, geometry, and estimates of bending strength. Materials and Methods Participants were classified as either weight gainers (WG, n = 23) or stable weight (SW, n = 48) using a random coefficients model. Weight gainers had positive increases in weight (p < 0.05) at each clinic visit from age 17 onward. Proximal femur DXA scans (Hologic QDR 2000) taken annually from 17 to 22 yr of age were analyzed for areal BMD (g/cm2), subperiosteal width (cm), and bone cross-sectional area (CSA) at the proximal femoral shaft. Cortical thickness was measured, and section modulus (Z, cm3) was calculated as a measure of bone bending strength. Total body lean (g) and fat (g) mass were measured from DXA total body scans. Results Over ages 17–22, height remained stable in both groups. Weight remained static in the SW group but increased 14% on average in the WG group (p < 0.05). After controlling for age 17 baseline values, WG had higher BMD (+2.6%), thicker cortices (+3.6%), and greater bone CSA (+2.3%). Increased BMD did not translate to greater increases in bone bending strength (Z). The SW group achieved similar gains in Z by greater subperiosteal expansion. Bone strength index (SI = Z/height) normalized for body weight remained constant in the SW group but decreased significantly in the WG group. In contrast, SI normalized to lean mass did not change over time in either group. Other variables including physical activity, nutrition, and hormone levels (estradiol, testosterone, cortisol) did not differ significantly between groups. Conclusions These data suggest that weight gain in late adolescence may inhibit the periosteal expansion known to normally occur throughout life in long bones, resulting in decreased bone strength relative to body weight.

Güner, Olcay

2017-03-01

The Early Maladaptive Schema Questionnaires Set for Children and Adolescents (SQS) was developed to assess early maladaptive schemas in children between the ages of 10 and 16 in Turkey. The SQS consists of five questionnaires that represent five schema domains in Young's schema theory. Psychometric properties (n = 983) and normative values (n = 2250) of SQS were investigated in children and adolescents between the ages of 10 and 16. Both exploratory and confirmatory factor analyses were performed. Results revealed 15 schema factors under five schema domains, with good fit indexes. A total of 14 schema factors were in line with Young's early maladaptive schemas. In addition to these factors, one new schema emerged: self-disapproval. Reliability analyses showed that SQS has high internal consistency and consistency over a 1-month interval. Correlations of SQS with the Adjective Check List (ACL), the Inventory of Parent and Peer Attachment (IPPA), the Symptom Assessment (SA-45) and the Young Schema Questionnaire (YSQ) were investigated to assess criterion validity, and the correlations revealed encouraging results. SQS significantly differentiated between children who have clinical diagnoses (n = 78) and children who have no diagnosis (n = 100). Finally, general normative values (n = 2,250) were determined for age groups, gender and age/gender groups. In conclusion, the early maladaptive schema questionnaires set for children and adolescents turned out to be a reliable and valid questionnaire with standard scores.Copyright © 2016 John Wiley & Sons, Ltd. The early maladaptive schema questionnaires set for children and adolescents (SQS) is a psychometrically reliable and valid measure of early maladaptive schemas for children between the ages of 10 and 16. SQS consists of five schema domains that represent Young's schema domains including 15 early maladaptive schemas and 97 items. Normative values for each schema were determined for age, gender and age/gender groups. Clinically, SQS presents valuable information about early maladaptive schemas during childhood and adolescence, before such schemas become more pervasive and persistent.

[Comparative study of the subjective emotional experience among adolescents showing depressive symptoms associated or not with risk-taking behavior].

Relationships between risk-taking behavior and depressive disorders in young people are considered as a complex psychopathological problem. Previous findings showed strong correlations between substance abuse, risk-taking behavior and depressive symptoms. Nevertheless, questions remain concerning potential common factors of depression and risk-taking behavior. Besides research focusing on personality dimensions, some others highlight the role played by emotions and their pathological aspects. In these studies, pathological emotional processing such as alexithymia or specific deficit in emotional intensity was linked to both risk-taking behavior and depressive disorders. The aim of this study was to investigate potential specific emotional profiles of adolescents engaged in pathological risk-taking or depressive symptomatology, versus adolescents presenting an association of both. Four hundred and eigty-eight adolescents (m(age)=14,93, SD=1,44), with 257 boys (m(age)=15, SD=1,51) and 231 girls (m(age)=14,52, SD=1,23), were spread into four groups: adolescents engaged in high level risk-taking, adolescents showing both high risk-taking and high depressive symptoms, depressed adolescents, and a control group without any pathological aspects. The four groups completed a set of three assessments: Youth Risk Behavior Surveillance Scale (YRBSS), Level of Emotional Awareness Scale (LEAS) and Differential Emotional Scale (DES). Adolescents engaged in risk-taking have the lowest level of emotional awareness and subjective emotional intensity, while adolescents of the second group (depression with risk-taking behavior) have a higher level on both measures. Depressed adolescents present the highest score of emotional awareness within the pathological groups, lower than controls. Paradoxically, their ability to represent themselves others' emotions were higher than the control group, just as the intensity of their subjective emotional experience in case of negative emotions. The results may be explained by a specific developmental hypothesis, in which emotional awareness growth from the early period of life to late childhood, allowing children to gradually experiment more and more complex subjective emotional experiences. However, early exposure to traumatic experiences or inadequate environment may lead to developmental arrests, in which emotional awareness is weak. In this case, a lack of emotional information caused by low emotional awareness may have pathological issues, in terms of depression and risk-taking behavior. Clinical implications of this interpretation are discussed. Copyright © 2010 L’Encéphale, Paris. Published by Elsevier Masson SAS. All rights reserved.

Adolescence is characterized both by a large developmental potential and by an increased risk for emergence of different forms of psychopathology. International classifications of mental disorders recognize the psychopathology of adolescence at the age of 15−18 through the categories of conduct disorders and some forms of addiction: chemical and non-chemical. The aim of this research was to analyse the personality structure among four groups of adolescents manifesting different types of conduct disorder based on Cloninger’s Psychobiological theory of personality. The research sample consisted of 140 respondents at the age of 16−18, divided into five groups: 30 respondents manifesting socialized conduct disorder, 20 adolescents in conflict with the law, 30 respondents manifesting abuse of psychoactive substances, 30 respondents with the problem of the Internet addiction and 30 from general population. The Belgrade Adolescent Personality Inventory (BAPI) questionnaire was used for the purpose of assessment of personality. Multivariate analysis of variance (MANOVA), followed by univariate analysis of variance (ANOVA) was used to examine differences between the given groups of adolescents. The results of MANOVA show differences in the personality structure among the groups, both in the dimensions of temperament, F (20,418.84) = 2.71, p < 0.001, Wilks’s lambda 0.67, and in the dimensions of character, F (12,344.24) = 3.27, p < 0.001, Wilks’s lambda is 0.75. Socialized conduct disorder is characterized by low selfdirectedness and average cooperativeness. Adolescents in conflict with the law have the lowest persistence, together with low self-directedness and cooperativeness. Adolescents abusing psychoactive substances have low harm avoidance and self-transcendence. Adolescents with Internet addiction are characterized by high novelty seeking (impulsivity and curiosity), low self-directedness and the lowest cooperativeness. The results show that the dimensions of personality can play an important role in etiopathogenesis of various disorders in adolescents.

The aim was to examine the relationship between orthodontic treatment need and Oral Health-Related Quality of Life (OHRQoL) among Lithuanian adolescents aged 11⁻18 across gender and age groups. A representative cross-sectional study of 911 adolescents aged 11⁻18 (mean (M) = 15.53; Standard Deviation (SD) = 1.52) was conducted in 26 public schools. The schoolchildren completed the Child Perceptions Questionnaire to evaluate their OHRQoL. The Index of Orthodontic Treatment Need (IOTN) was used to evaluate the severity of malocclusion. The strength of association between variables was evaluated via negative binomial regression estimating the ratio of sum score means (RSSM). A worse OHRQoL score was associated with a higher grade of IOTN; however, only the Emotional and Social wellbeing domains were significantly affected by malocclusion (RSSM = 1.158; 95% Confidence Interval (CI): 1.083⁻1.237 and RSSM = 1.205; 95% CI: 1.114⁻1.304, respectively). The significant association was identified only among females (RSSM = 1.264; 95% CI: 1.176⁻1.359). A significant association was observed in all age groups for Emotional and Social well-being domains but only in the oldest age group for Oral Symptoms and Functional Limitations domains. Malocclusion has a negative impact on the OHRQoL of young people with emotional and social aspects being the most affected. Girls and older adolescents suffered from malocclusion more than boys and their younger counterparts.

The impact of the age and sex adjusted body mass index (ISO-BMI) in the obese vs. non-obese children and adolescents with cholecystectomy for cholelithias is rarely reported. The national database was searched for cholecystectomies performed in paediatric patients between 1997 and 2011, and the 59 paediatric and adolescent patients having cholecystectomy in the Kuopio University Hospital district were divided in two groups by age and sex adjusted BMI (ISO-BMI) using the cut-off point of overweight (ISO-BMI 25 kg/m(2)) based on the Finnish growth standards. Nationwide a total of 840 cholecystectomies were performed during the 15 years study period in Finland, most of which included females (77%), resulting in a mean of annual frequency of 4.8 (range: 3.9-6.1) procedures/100,000 population. In the study sample, most of the patients with the cholelithiasis were female (50/59, 85%). The gender distribution was equal among the younger patients, but among adolescents 6/52 (12%) of the patients with cholelithiasis were boys and 46/52 (88%) of the patients with cholelithiasis were girls. Obesity did not affect on operative parameters. The median operative time was 70 min (range, 30-155) and 66 min (44-130) in the high ISO-BMI-group. The recovery was similar in the two groups: the median length of hospital stay was 4 days in both groups. The patients in the low ISO-BMI-group vs. high ISO-BMI-group had a trend of higher serum bilirubin (p=0.16) and serum AFOS values (p=0.19). In the histological examination of the gallbladders 19/28 (68%) patients in the low ISO-BMI-group had inflammation vs. 26/31 (84%) patients in the high ISO-BMI-group (p=0.15). Our results between obese and non-obese children and adolescents with cholelithiasis are not statistically significant. The obese adolescents with female gender are in greater risk for cholelithiasis. Copyright © 2014 International Institute of Anticancer Research (Dr. John G. Delinassios), All rights reserved.

Audience effects on the neural correlates of relational reasoning in adolescence.

Adolescents are particularly sensitive to peer influence. This may partly be due to an increased salience of peers during adolescence. We investigated the effect of being observed by a peer on a cognitively challenging task, relational reasoning, which requires the evaluation and integration of multiple mental representations. Relational reasoning tasks engage a fronto-parietal network including the inferior parietal cortex, pre-supplementary motor area, dorsolateral and rostrolateral prefrontal cortices. Using functional magnetic resonance imaging (fMRI), peer audience effects on activation in this fronto-parietal network were compared in a group of 19 female mid-adolescents (aged 14-16 years) and 14 female adults (aged 23-28 years). Adolescent and adult relational reasoning accuracy was influenced by a peer audience as a function of task difficulty: the presence of a peer audience led to decreased accuracy in the complex, relational integration condition in both groups of participants. The fMRI results demonstrated that a peer audience differentially modulated activation in regions of the fronto-parietal network in adolescents and adults. Activation was increased in adolescents in the presence of a peer audience, while this was not the case in adults. Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.

Our research, partly experimental and partly prospective, was conducted for the purpose of evaluating the efficiency of reproductive health education given to adolescents during the postpartum period. The study comprised with 120 adolescents aged 15 to 19 (60 experimental group, 60 control group). Follow-up was conducted every 3 months for a total of 12 months, and the study concluded with 55 individuals from the experimental group and 46 individuals from the control group having participated fully, for the full 12 months. At the end of the research, it was found that the reproductive health knowledge of the experimental (103.10 ± 11.43) and control (99.15 ± 9.53) groups were similar before education. A statistically significant difference was also found between the total points for the scale determining the reproductive health of the experimental and control groups before and after education (P < .001). The socio-demographic variables affecting the total points for the scale determining the reproductive health-protective behavior of women were evaluated by multiple regression analysis; the most effective variables were found to be age and educational status. A statistically significant difference was also found between the total points for the family planning behavior scale of the experimental and control groups before and after education (P < .001). From this, it was understood that reproductive health education given during the postpartum and follow-up periods has a positive effect on adolescents' developing reproductive health behaviors and on creating knowledge and awareness related to family planning behavior. But there needs to be follow-up and supporting specific for adolescents in the current health system. Copyright © 2015 North American Society for Pediatric and Adolescent Gynecology.

Objective Social phobia typically develops during the adolescent years, yet no nationally representative studies in the United States have examined the rates and features of this condition among youth in this age range. The objectives of this investigation are to: (1) present the lifetime prevalence, sociodemographic and clinical correlates, and comorbidity of social phobia in a large, nationally representative sample of U.S. adolescents; (2) examine differences in the rates and features of social phobia across the proposed DSM-5 social phobia subtypes. Method The National Comorbidity Survey Replication-Adolescent Supplement (NCS-A) is a nationally representative face-to-face survey of 10,123 adolescents aged 13–18 years in the continental U.S. Results Approximately 9% of adolescents met criteria for any social phobia in their lifetime. Of these adolescents, 55.8% were affected with the generalized subtype and 44.2% exhibited non-generalized social phobia. Only 0.7% met criteria for the proposed DSM-5 performance only subtype. Generalized social phobia was more common among female adolescents and risk for this subtype increased with age. Adolescents with generalized social phobia also experienced an earlier age of onset, higher levels of disability and clinical severity, and a greater degree of comorbidity relative to adolescents with non-generalized forms of the disorder. Conclusions This study indicates that social phobia is a highly prevalent, persistent, and impairing psychiatric disorder among adolescent youth. Results of this study also provide evidence for the clinical utility of the generalized subtype and highlight the importance of considering the heterogeneity of social phobia in this age group.

Adolescence in an age of opportunity in Thailand. The main health issues of this age group are related to pregnancy, injuries and poisoning, all which should be preventable. This article presents the experiences of Thai physicians, who received adolescent medicine fellowship training in North America and brought their experience, knowledge, skills, and adolescent health care principles and practice back to Thailand. The anticipations and the facts faced in everyday practice, training, research, and collaboration in a place with their own culture and societal norms are described. Currently, there are six adolescent medicine specialists who work with experienced specialist in the subcommittee of adolescent health under the Royal College of Pediatricians of Thailand. There has been collaboration with both the public sector and health care sector, government and non-government organizations with regards to health care service and promotion. Many hospitals especially residency training institutes have increased the cut-off age of patients to be seen by pediatricians to 15 or 18 years of age. Since 2011, adolescent medicine was made one of the mandatory rotations in all pediatric resident training programs. There is still more work to be done - issues around policies for confidentiality and a lower age of consent, collaboration between other specialties to enable a large-scale youth-friendly one-stop services, and multicenter research opportunities are still awaiting.

Paradoxically, recent investigations have showed that adiponectin levels are inversely associated with muscle strength. However, to date, there is a lack of knowledge on the relationship between muscular fitness (MF) and adiponectin levels in adolescents. We aimed to examine the independent associations between MF and adiponectin levels in adolescents, controlling for several potential confounders. This is a cross-sectional analysis with 529 Portuguese adolescents aged 12-18 years. A MF score was computed as the mean of the handgrip strength and standing long jump standardized values by age and gender. We measured fasting glucose, insulin, HDL-cholesterol, C-reactive protein and adiponectin. Linear regression analysis showed a significant inverse association between adiponectin (Z-score by age and sex) and MF score, after adjustments for age, sex, pubertal stage, socioeconomic status, adherence to the Mediterranean diet, body mass index, HOMA-IR, HDL-cholesterol, C-reactive protein and cardiorespiratory fitness (unstandardized β = -0.176; p < 0.005). Analysis of covariance showed a significant difference between the Low MF/Non-overweight group and the High MF/Non-overweight Group (p < 0.05) and between the Low MF/Non-overweight and High MF/Overweight Group (p < 0.05) (F (5, 523) = 2.262, p = 0.047). Adiponectin circulating levels are inversely and independently associated with MF. In non-overweight adolescents, those with high levels of MF presented lower levels of adiponectin compared to those with Low MF. Likewise, overweight adolescents with High MF presented lower levels of serum adiponectin than non-overweight adolescents with Low MF.

Empathic accuracy: age differences from adolescence into middle adulthood.

PubMed

Kunzmann, Ute; Wieck, Cornelia; Dietzel, Cathrin

2018-02-01

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

Assessment of the correlation between the atherogenic index of plasma and cardiometabolic risk factors in children and adolescents: might it be superior to the TG/HDL-C ratio?

Most of the studies investigating the correlation between the atherogenic index of plasma (AIP) and cardiometabolic risk factors have been conducted with adults, while only a limited number of related studies that involved children and adolescents has been conducted. The purpose of this study is to assess the correlation between the AIP and other cardiometabolic risk factors in adolescents. This study was conducted with 310 girls and 90 boys who were between the ages of 6 and 18 years. After a 10-h fasting period, the biochemical values of the participants were measured in the morning. The anthropometric measurements of the participants were also taken. The AIP was calculated as Log10 (triglycerides/high density lipoprotein-cholesterol; TG/HDL-C). In adolescents between the ages of 12 and 18, the mean AIP of the group with TG ≥130 mg/dL was significantly higher than that of the groups with TG of 90-129 mg/dL and <90 mg/dL. There was a strong correlation between TG and AIP for both boys and girls among the children and adolescents, while there was a strong correlation between the TG/HDL-C ratio and TG only in the boys who were within the 6-11-year-old age group. An increase in AIP is associated with cardiovascular risk factors in children and adolescents other than those seen in adults. Based on the TG/HDL-C ratio, the AIP may be superior as a complementary index in the assessment of cardiometabolic risks in children and adolescents.

Weight and dimensions of the pituitary (hypophysis cerebri) obtained from medicolegal autopsies of northwestern Indian subjects, which included 87 children and adolescents and 798 adults were recorded. Volume of the pituitary was determined in 100 specimens. In addition, anteroposterior and vertical measurement of pituitary were taken in mid-sagittal sections of the head in magnetic resonance images (MRI) of 130 living adults. In the males, the weight of pituitary increased steadily from 102.52 +/- 38.66 mg in the age group of 0-5 years to 427.83 +/- 117.15 mg in the age group of 36-45 years, it decreased thereafter. In the females, the weight increased from 166.10 +/- 38.70 mg in the first age group to 445.90 +/- 168.60 mg in the age group of 16-17 years and became erratic thereafter. The mean weight of the gland in female subjects was always more than in the males of the corresponding ages till 35 years (p < 0.001, p < 0.01, p < 0.05). The maximum weight of the pituitary was observed during adolescence in the females. When weights of the gland of all the age groups were pooled together in adults the average weight was 401.26 +/- 105.89 mg in the males and 417.32 +/- 104.07 mg in the females. The weight and dimensions of the gland in northwestern Indian subjects were smaller than those in the western Caucasians and Japanese. In mid-sagittal MRI pictures of the head, the anteroposterior and vertical measurement of pituitary were about one mm greater than in the autopsy specimens. In the males, weight of the gland was significantly related to body weight in children, adolescents and adults; it was related to supine body length only in the adults. In the females, weight of the gland was significantly correlated with age in all the age group except in the age group of 36-55 years.

Analyses of children and young people mortality continue to be an important component of health monitoring of this population. Such analyses provide the basis to assess the overall trends, the structure of the causes of death over longer periods, and the differences between Poland and other countries. The purpose of the current study is to present the current status and the direction of changes since 2000 with regard to the level and underlying causes of mortality in children and adolescents aged 1-19 years in Poland on the background of statistics for leading European countries. Interactive databases available online: the National Demographic Database provided by the Central Statistical Office and the International WHO-MDB Database were used. Poland, constantly belonging to Eur-B category, was compared with the combined group of 27 leading countries, classified as a very low total mortality group (Eur-A) according to WHO. Linear trends of overall and cause-specific mortality in 2000-2013 were estimated. The causes of death have been presented according to the main classes of the 10th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-10). External and other causes were adopted as the two principal categories. In 2015, 1471 deaths of persons aged 1-19 were recorded in Poland (19.9 per 100 000, 25.4 and 14.2 for boys and girls, respectively). Changes in children and adolescents mortality by age have a non-linear nature (U-shaped), and the lowest level is recorded at the age of 5-9 years. According to 2014 data, 50.2% of deaths of children and adolescents aged 1-19 years occurred due to external causes, including non-intentional and intentional ones. This percentage increased from 18.4% in the 1-4 age group to 68.6% at the age of 15-19 years. Apart from external causes, the dominating causes of death are malignant neoplasms, congenital defects, or nervous system and respiratory system diseases. The ranking of those causes of death changes in successive age groups and over time. When age is considered, a higher proportion of congenital defects and respiratory system diseases was found in mortality younger children and a higher proportion of circulatory system diseases and undefined cases in mortality of adolescents. When trends were studied, a continuing elimination of infectious diseases was observed together with growing impact of rare diseases in all age groups. The excess mortality of Polish population at age 1-19 by comparison to Eur-A countries increased from 21% in 2000 to 56% in 2013, mainly due to unfavourable trends in adolescents. The rate of decline in the mortality of young children (1-4 years) was greater than in Eur-A countries, both in case of external and other causes. In the age group 5-14 years the higher rate of change was sustained only with regard to external causes. Among adolescents and young adults, the distance between Poland and Eur-A countries increased during the studied period. The shape of trend in the 15-24 age group was unfavourable for Poland, mainly with respect to external causes. This observation could be in part explained by increasing suicide trend in Poland since 2008, coexisting with rather constant level in Eur-A countries. The mortality rate among the population aged 1-19 years in Poland is systematically decreasing, but it still exceeds the average level recorded in leading European countries, particularly in relation to adolescents. When assessing the ability to reduce mortality in Poland to the level of Eur-A countries, attention must be paid to the causes considered as avoidable. Further studies ought to focus on the trends and international comparisons only foreshadowed in this study with regard to individual diagnoses, discussing possible preventive measures. Introduction of an ICD-11 classification will enable more accurate coding of causes of death, including a more precise analysis of the burden of rare diseases, which are an increasing challenge to public health in the population at the developmental age.

This analysis examined associations between the salivary dim light melatonin onset (DLMO) phase and self-selected sleep/ wake schedules in groups of children and adolescents during summer vacation and during the school year to determine the degree to which sleep/wake patterns can estimate salivary DLMO phase. Participants slept at home on self-selected schedules for 5 consecutive nights and reported their bedtime and wake-up time via daily telephone messages. Salivary melatonin was sampled in the laboratory on one evening every 30 minutes in dim light (< 50 lux) to determine DLMO phase. Within group bivariate regressions between sleep pattern measures (bedtime, wake-up time, and midsleep time) and DLMO phase were computed. One group, ages 9 to 17 years (mean age = 12.5, SD = 2.3 years, 74 males, 75 females) contributed 149 DLMO phase and sleep/wake pattern measures while on a school year schedule ("school group"). A separate group, ages 9 to 16 years (mean age = 13.1, SD = 1.3 years, 30 males, 29 females) contributed 59 DLMO phase and sleep/wake pattern measures while on a summer schedule ("summer group"). Bedtime, midsleep time, and wake-up time were positively correlated with DLMO phase in both groups. Although all correlation coefficients for the summer group were statistically greater compared to the school group, the regression equations predicted DLMO phase within +/- 1 hour of the measured DLMO phase in approximately 80% for both groups. DLMO phase can be estimated using self-selected sleep/wake patterns during the school year or summer vacation in healthy children and adolescents.

Purpose While actigraphy has gained popularity in pediatric sleep research, questions remain about the validity of actigraphy as an estimate of sleep-wake patterns. In particular, there is little consistency in the field in terms of scoring rules used to determine sleep onset latency. The purpose of this study was to evaluate different criteria of immobility as a measure of sleep onset latency in children and adolescents. Methods Ninety-five youth (ages 3-17 years, 46% male) wore both the Ambulatory-Monitoring Inc. Motionlogger Sleep Watch (AMI) and the Philips Respironics Mini-Mitter Actiwatch-2 (PRMM) during overnight polysomnography in a pediatric sleep lab. We examined different sleep onset latency scoring rules (3, 5, 10, 15, and 20 minutes of immobility) using different algorithms (Sadeh and Cole-Kripke) and sensitivity settings (Low, Medium, High) for the devices. Comparisons were also made across age groups (preschoolers, school-aged, adolescents) and sleep disordered breathing status (no obstructive sleep apnea [OSA], mild OSA, clinically significant OSA). Results For the AMI device, shorter scoring rules performed best for children and longer scoring rules were better for adolescents, with shorter scoring rules best across sleep disordered breathing groups. For the PRMM device, medium to longer scoring rules performed best across age and sleep disordered breathing groups. Conclusions Researchers are encouraged to determine the scoring rule that best fits their population of interest. Future studies are needed with larger samples of children and adolescents to further validate actigraphic immobility as a proxy for sleep onset latency. PMID:25687438

Objective To experimentally examine if adolescents with excess weight are more sensitive to social stress and hence more sensitive to harmful effects of stress in cognition. Design and Methods We conducted an experimental study in 84 adolescents aged 12 to 18 years old classified in two groups based on age adjusted Body Mass Index percentile: Normal weight (n=42) and Excess weight (n=42). Both groups were exposed to social stress as induced by the virtual reality version of the Trier Social Stress Task --participants were requested to give a public speech about positive and negative aspects of their personalities in front of a virtual audience. The outcome measures were salivary cortisol levels and performance in cognitive tests before and after the social stressor. Cognitive tests included the CANTAB Rapid Visual Processing Test (measuring attention response latency and discriminability) and the Iowa Gambling Task (measuring decision-making). Results Adolescents with excess weight compared to healthy weight controls displayed increased cortisol response and less improvement of attentional performance after the social stressor. Decision-making performance decreased after the social stressor in both groups. Conclusion Adolescents who are overweight or obese have increased sensitivity to social stress, which detrimentally impacts attentional skills. PMID:25898204

Pregnancy among unmarried adolescents has been linked to negative personal control beliefs. In contrast, self-agency beliefs about control over future possibilities have been linked to delay in subsequent childbearing. In this secondary analysis, we examined factors associated with self-agency change in 429 unmarried adolescent mothers from intervention and control groups of a nurse home visitation study. Adolescent mothers who participated in a sustained relationship with a nurse made greater gains in self-agency than did control group mothers (p = .034). Adolescents with lower cognitive ability who were behind their age-appropriate grade level in school made the greatest self-agency gains. Copyright © 2013 Wiley Periodicals, Inc.

Physical family violence and externalizing and internalizing behaviors among children and adolescents.

Family violence has been associated with various negative outcomes among children and adolescents. Yet, less is known about how unique forms of physical family violence contribute to externalizing and internalizing behaviors based on a child's developmental stage. Using data from the Illinois Families Study and administrative Child Protective Services data, we explored the relation between 3 types of physical family violence victimization and externalizing and internalizing behaviors among a sample of 2,402 children and adolescents. After including parent and family level covariates in Poisson regressions, we found that a unique form of family violence victimization was associated with increased externalizing behaviors among children at each age group: exposure to physical intimate partner violence (IPV) among children ages 3-5, exposure to the physical abuse of a sibling among children ages 6-12, and child physical abuse among adolescents ages 13-18. No form of physical family violence was significantly associated with internalizing behaviors for children in any age group. Including exposure to the child maltreatment of a sibling is crucial when attempting to contextualize children's responses to family violence and providing comprehensive services in an effort to enhance the well-being of all children in a family.

This study analyzed the presence of DP symptoms in a sample of both psychiatric patients and normal subjects, addressing the issue of DP symptoms in adolescence. A total of 267 subjects (149 patients and 118 healthy controls) aged between 14 and 65 years, were assessed by means of CDS, the SCID-I and the K-SADS. The sample was then divided into two subsamples with a cut-off age of 21 years. As expected CDS score was significantly higher in the patient group compared to the healthy control group. As for the age issue, among patients no statistical difference was found comparing subjects over and under 21 years, whereas in the sample of healthy controls, subjects under 21 years reported CDS scores significantly higher. While in adults DP symptoms are frequently associated with mental disorders, in adolescents they could be considered as a quasi-physiological phenomenon. Copyright © 2015 Elsevier Inc.

Female sexual dysfunction and adolescents.

PubMed

Greydanus, Donald E; Matytsina, Lyubov

2010-10-01

To review recent publications in the area of sexual dysfunction in females including the adolescent age group. Though as many as 40% of adult females have a sexual dysfunction, the incidence among adolescent females is unknown. Though over half of adolescents are sexually active, sexual dysfunction is not a term universally accepted among the general public as well as researchers. Research on sexual dysfunction in females typically starts with age 18 years or over. Causes of sexual dysfunction include medical disorders, gynecological problems, which started from the adolescent age, psychiatric disorders, and complications of medications such as selective serotonin reuptake inhibitors (SSRIs), antipsychotics, and others. Management includes identification of the specific sexual dysfunction and treatment of the underlying condition, including surgical treatment in such cases as absent vagina or obstetrics fistula. Psychological therapy is helpful when psychological factors are contributory to the dysfunction. Pharmacologic principles of management cases can, for example, include treatment of gynecological problems such as pelvic inflammatory disease (PID) or endometriosis as a cause of sexual dysfunction or include removal of the offending drug, use of glutamatergic strategies or trazodone in SSRI-association dysfunction, and addition of bupropion or other medications in select cases. No medication is FDA-approved for sexual dysfunction in females. Sexual dysfunction in females includes lack of sexual desire, sexual pain disorders (as dyspareunia), anorgasmia, and sexual arousal dysfunction. Acceptance of the high incidence of sexual dysfunction in all female populations is necessary to appreciate this phenomenon in the adolescent cohort, because some gynecological disease can arise from the adolescent age and can cause sexual dysfunction. Some sexual dysfunctions require immediate treatment, including surgical in the case of congenital anomaly, ovarian cyst, or tumor. Current understanding is based on extrapolation of research in the adult population. Management principles include removal of offending drugs and treatment of underlying disorders. Research in the adolescent population is recommended for more understanding and acceptance of this phenomenon in this age group.

Objective: To understand and evaluate the prevalence of myopia and its trend in children and adolescents aged 7-18 years in Han ethnic group in China from 2005 to 2014, and provide evidence for the prevention of myopia. Methods: The data of 2005, 2010 and 2014 Chinese National Students Constitution and Health Surveys were collected. The children and adolescents with complete detection data of binoculus were selected as study subjects. The sample size of three studies were 233 108, 215 319 and 212 743, respectively. The method of curve fitting was used to simulate the myopia detection increase model and analyze the gender and area specific myopia detection increase trends and characteristics from 2005 to 2014. Results: The overall myopia detection rate increased gradually in the children and adolescents aged 7 to 18, which was 47.5 % in 2005, 55.5 % in 2010 and 57.1 % in 2014, respectively. The increase slowed in 2014. A"parabola" shape of myopia detection increase rate was observed. Myopia detection rate increased with age before puberty and decreased with age after puberty gradually. A"cross phenomenon" of myopia detection increase was observed in boys and girls between urban and rural areas. The increase of myopia detection was mainly in urban students before puberty and in rural students after puberty. The age of myopia prevalence peak has become earlier constantly in children and adolescents aged 7-18 years from 2005 to 2014, which was 13 years old in 2005, 12 years old in 2010 and 11 years old in 2014. The increase rate was about 7 % . During 2005-2014, the increase rate of myopia detection gradually increased in younger students and tended to zero in older students. Conclusion: The detection rate of myopia was still high in children and adolescents in China. The age of myopia prevalence peak has become earlier gradually.

Objectives To evaluate the incidence and outcomes of self-harm from ambulance records. Design A retrospective, observational study. Setting Osaka City, Japan. Participants A total of 365 adolescents aged 10–19 years with emergency self-harm such as poisoning by drugs or gas, cutting skin, jumping from heights, hanging and drowning and treated by emergency medical service personnel from January 2010 through December 2012. Primary outcome measurements Incidence per 100 000 persons and outcome at the scene or hospital arrival by age and gender. Poisson regression models for incidence evaluation were used; reporting relative risks (RRs) and their 95% CIs. Results During the study period, a total of 425 self-harm events were documented in 365 adolescents. The incidence of self-harm increased significantly between the ages of 11 and 19 years, from 6.3 to 81.0 among boys and the ages of 12 and 19 years from 6.3 to 228.3 among girls, respectively (both p<0.001). Although there was no incidence difference between girls and boys in the group aged 11–14 years (RR 1.20; 95% CI 0.59 to 2.47), the incidence was significantly higher among girls than boys in the group aged 15–19 years (RR 4.18; 95% CI 3.20 to 5.45). The overall proportion of death by self-harm was 4.9%. The proportion of hospital admission and death by self-harm was higher among boys than among girls (38.6% vs 25.2%, p=0.016 and 14.8% vs 2.4%, p<0.001). Conclusions The incidence of emergency treatment for self-harm by adolescents increased with age and our findings also demonstrated the gender paradox. It would be necessary to establish active, gender-specific and comprehensive prevention strategies for adolescent self-harm, based on our findings showing the age and gender differences of self-harm among adolescents.

To assess the effect of the solution-focused approach interview technique on overweight/obese adolescents' nutrition-exercise attitudes and behaviours. Obesity is a serious health problem for all age groups, particularly adolescents; therefore, it is important for adolescents to develop healthy nutrition habits and acquire exercise behaviours. Unless healthy nutrition-exercise behaviours are acquired, obesity can develop in adolescence, continue in adulthood. Focusing on solutions can be effective for overweight/obese adolescents to develop healthy nutrition-exercise behaviours. A pretest-post-test randomised controlled trial design was used. The study included 32 overweight/obese adolescents (16 for intervention group, 16 for control group) aged 12-13 years who attended a health centre and met the inclusion criteria. The solution-focused Approach interview technique was applied to the intervention group. Eight solution-focused interviews were conducted with each adolescent at 2-week intervals (interview length 30-45 min). For each group, anthropometric, metabolic measurement follow-ups were conducted in the first and sixth months. The data were evaluated using independent samples t test, Mann-Whitney U, Wilcoxon test, respectively, for normally, non-normally distributed variables. The categorical variables were compared using chi-square test. The value p < .05 was accepted to be statistically significant. The study concluded that the intervention group's healthy nutrition-exercise attitude and behaviour scale scores were higher in the sixth month follow-up; difference between the follow-ups was significant (p < .001). The study also showed that the intervention group lost 2.6-11 kg, while the control group gained 2.9-9 kg. A significant positive relationship was found between the nutrition-exercise attitude and behaviour scores. Eight interviews during 6 months were adequate for positive development of their nutrition-exercise attitudes and behaviours; significant decrease in their weight, BMI percentile, BMI-SDS values; and normal metabolic values. The solution-focused approach interview technique enabled overweight/obese adolescents' weight and blood glucose to be controlled against obesity. It helped them acquire healthy nutrition-exercise behaviours. Thus, it can be used as support for treatment of obesity in adolescents. © 2017 John Wiley & Sons Ltd.

This study aimed to identify different groups of adolescents who have distinct profiles based upon their perceptions of interpersonal and activity-based dimensions of the sport environment. A sample of 310 adolescents from Eastern Canada (M age  = 14.69 ± 1.60 years; 54.8% girls) completed questionnaires assessing selected interpersonal, activity-based, demographic and sport-specific variables. Using TwoStep Cluster Analysis, we identified three groupings of adolescent sport participants. Consistent with the literature, we labeled these groups 'negative context,' 'positive context,' and 'complex context,' respectively. As expected, participants in the last two groups reported greater enjoyment, perceived competence, and commitment to sport. Further, participants in the 'complex context' group showed the highest levels of sport commitment. We draw on insights from Csikszentmihalyi's theory of complexity and relational conceptions of compensation and resilience to interpret the findings, and offer an alternative account of contextual conditions suitable for adolescents involved in competitive sport.

Purpose Forming secure friendship attachments during adolescence are important for mental health; few, however, have specifically examined the ways in which the transitions in attachment during adolescence may influence future mental health outcomes among African-Americans. Method The current study examines how transitions in attachment in adolescence predicted changes in depression symptoms from late adolescents through adulthood in an African-American sample of adolescents. We used growth curve modeling to examine the association between transitions in friendship attachment and changes in depression symptoms in adulthood. Results At age 16, 346 (64.0%) reported secure attachment with 195 (36.0%) reporting either avoidant or resistant attachment. At age 17, 340 (62.9%) reported secure attachment and 201 (37.2%) reported avoidant or resistant attachment. The largest percentage of participants (46.2%) reported stable-secure attachment across the two time points. Results of the growth model indicated that adolescents who reported a stable-secure attachment style had lower levels of depression symptoms during adulthood than those individuals who transitioned from secure-to-insecure, from insecure-to-secure, or were in the stable-insecure group. Interestingly enough, individuals in both of the attachment transition groups had a faster declining rate of depression symptoms over time compared to the two stability groups. Conclusion Data support existing research showing an association between transitions in attachment during adolescence and depression through adulthood. Further these study findings suggest there may be protective features associated with transitioning between attachment styles during adolescence on later depression, compared to African-American’s who remain stable in their attachment style.

The idea that individuals who help others incur health benefits themselves suggests a novel approach to improving health while simultaneously promoting greater civic orientation in our society. The present study is the first experimental trial, to our knowledge, of whether regular volunteering can reduce cardiovascular risk factors in adolescents. To test a novel intervention that assigned adolescents to volunteer with elementary school-aged children as a means of improving adolescents' cardiovascular risk profiles. Randomized controlled trial, with measurements taken at baseline and 4 months later (postintervention). Urban public high school in western Canada. One hundred six 10th-grade high school students who were fluent in English and free of chronic illnesses. Weekly volunteering with elementary school-aged children for 2 months vs wait-list control group. Cardiovascular risk markers of C-reactive protein level, interleukin 6 level, total cholesterol level, and body mass index. No statistically significant group differences were found at baseline. Postintervention, adolescents in the intervention group showed significantly lower interleukin 6 levels (log10 mean difference, 0.13; 95% CI, 0.004 to 0.251), cholesterol levels (log10 mean difference, 0.03; 95% CI, 0.003 to 0.059), and body mass index (mean difference, 0.39; 95% CI, 0.07 to 0.71) compared with adolescents in the control group. Effects for C-reactive protein level were marginal (log10 mean difference, 0.13; 95% CI, -0.011 to 0.275). Preliminary analyses within the intervention group suggest that those who increased the most in empathy and altruistic behaviors, and who decreased the most in negative mood, also showed the greatest decreases in cardiovascular risk over time. Adolescents who volunteer to help others also benefit themselves, suggesting a novel way to improve health. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT01698034.

To compare, in vivo, differences in meibomian gland morphology between children and adolescents. Sixty-nine patients were included in this study and divided into two groups: children (n = 31; age range: 3 to 11 years) and adolescents (n = 39; age range: 12 to 18 years). Images of meibomian glands were obtained by infrared meibography and analyzed using ImageJ software (developed by the National Institutes of Health; available at http://rsb.info.nih.gov/ij/download.html). Meibomian gland loss, the number of meibomian gland ducts, the relative width of the meibomian gland ducts, and the percent area of the meibomian gland acini were compared between the two groups. Meibomian gland loss was found in both groups, but the meiboscore was not significantly different between the two groups (0.35 ± 0.6 vs 0.41 ± 0.8, t = -0.314, P > .05). The number of meibomian gland ducts (25.85 ± 3.25 vs 23.23 ± 3.06, t = -3.437, P < .05), relative width of the meibomian gland ducts (69.62% ± 5% vs 66.1% ± 7%, t = -2.454, P < .05), and percent area of the meibomian gland acini (57.7% ± 4% vs 55.5% ± 4%, t = 2.571, P < .05) in the upper eyelid were significantly greater in adolescents than in children. However, no significant differences were found in the lower eyelid between the two groups. Meibography is useful for the assessment of ocular surface conditions in children and adolescents. Meibomian gland loss occurs in both children and adolescents. The meibomian glands of the upper eyelid exhibit more morphological changes in adolescents than in children.

2010-05-01

Adolescent peer group self-identification refers to adolescents' affiliation with reputation-based peer groups such as "Goths" or "Jocks." These groups tend to vary on normative characteristics, including the group members' attitudes and behaviors. This article examined whether adolescents' baseline peer group self-identification predicted their self-reported relational and physical aggression 1 year later. Self-report data were collected from 1614 students from 9 regular and 9 continuation (alternative) high schools in Southern California, at baseline and 1-year follow-up. Subjects' mean baseline age was 15.21 years (SD = 1.18) and 51.6% of the subjects were female. Findings indicated that compared with self-identified "Regular" or "Normal" students, adolescents who identified with high-risk peer groups (eg, "Druggies,"Goths") tended to report higher relational and physical aggression 1 year later, controlling for baseline aggression and demographic variables. In addition, adolescents' self-identification with high-status peer groups (eg, "Jocks,"Populars") was predictive of higher relational aggression 1 year later. Gender and school type (ie, regular vs continuation) were not found to moderate these effects. It appears that peer group self-identification is a salient predictor of physical and relational aggression across gender and school type. Adolescents who identify with high-risk peer groups tend to report higher levels of physical as well as relational aggression in the future. In addition, adolescents who affiliate with elite groups tend to become more relationally aggressive over time. School-based prevention programs targeting aggression may benefit from addressing the impacts of peer group self-identification on adolescents' aggressive behavior.

Development in the organization of episodic memories in middle childhood and adolescence.

2013-01-01

The basic elements of autobiographical or episodic memory are established in early childhood, although the exact age at which memories gain episodic status is still under contention. The self-memory system proposed that adults use "lifetime periods" to group episodic memories together into chapters of the life story - an evolving and internalized account of significant life events that are self-defining. Two studies examined at what point in development children or adolescents begin to take advantage of lifetime-period chapters to organize their episodic memories. The results of Study 1 with 8- to 12-year-olds revealed that the ability to provide life story chapters began to emerge as early as 8 years of age. In Study 2 with adolescents aged 12-21, this ability continued to develop into late adolescence among New Zealand European (NZE) and New Zealand Chinese (NZC) adolescents; however, cultural differences also existed in the specificity of memories. NZC adolescents narrated fewer life story chapters containing specific memories than NZE adolescents. These findings support and extend current theories of episodic memory by specifying that pre-adolescents are starting to organize their episodic memories into lifetime periods, but this achievement is not fully realized until later in adolescence.

The effect of martial arts on adolescents' behavior, especially aggression, is controversial. The aim of this study was to assess and compare anger ratings among adolescent girl athletes of different martial arts. 291 female adolescents between the ages of 11 and 19 were assessed according to the Adolescent Anger Rating Scale designed by DM Burney. In the case group, the martial arts practiced were either judo (n = 70) or karate (n = 66), while the control group was composed of swimmers (n = 59) and nonathletes (n = 96). Total anger scores showed statistically significant differences between the groups (P = 0.001) decreasing from girls who practiced judo to nonathletes, karate, and swimmers. Instrumental and reactive anger subscales also showed significant differences between the groups, but this difference was not found for anger control. As a conclusion, the anger rate did not differ between judoka and nonathletes, but that both of these groups received higher scores in total anger than karateka and swimmers. PMID:22164178

Exploring adolescent views of body image: the influence of media.

Spurr, Shelley; Berry, Lois; Walker, Keith

2013-01-01

The purpose of this article is to present findings from two parallel qualitative studies that used focus groups to explore adolescent views of psychological wellness and healthy bodies. Nine focus groups were held with 46 adolescents aged 16-19 years from two Mid-Western Canadian high schools. Both studies were designed with an interpretive humanist perspective and then a 6-step thematic approach was used to analyze the data. Common themes emerging in the focus group discussions in both studies included the negative impact of media on adolescent body image and pressure to conform to the Western views of physical appearance. These findings illustrate the need for nurses to understand the influence of the media on adolescents' views of their body image and to incorporate protocols for assessment, education, and counseling of adolescents on the healthy usage of media into their pediatric clinical practice. Through consistent participation in the development and implementation of health policies, nurses play a critical role in supporting adolescents to develop healthy views of body image.

Race, Ethnicity, and Adolescent Violent Victimization.

The risk of adolescent violent victimization in the United States varies considerably across racial and ethnic populations; it is unknown whether the sources of risk also vary by race and ethnicity. This study examined the correlates of violent victimization for White, Black, and Hispanic youth. Data collected from 11,070 adolescents (51 % female, mean age = 15.04 years) during the first two waves of the National Longitudinal Study of Adolescent to Adult Health were used to estimate group-specific multilevel logistic regression models. The results indicate that male, violent offending, peer deviance, gang membership, and low self-control were significantly associated with increased odds of violent victimization for all groups. Some activities-including getting drunk, sneaking out, and unstructured socializing with peers-were risk factors for Black adolescents only; skipping school was a risk factor only for Hispanic adolescents. Although there are many similarities across groups, the findings suggest that minority adolescents are particularly vulnerable to violent victimization when they engage in some activities and minor forms of delinquency.

We analyze the impact of adolescent pregnancy in terms of social, familial, and educational changes during the subsequent years. Study participants included all adolescents delivering at an age of 17 years or less within a time frame of 5 years. A telephone interview was performed by using 16 self-developed questions as well as a well-recognized questionnaire on Life Satisfaction (FLZ(M)-A). Out of these 186 adolescents, 131 (70%) adolescents were available for the study. The adolescents were split in two study subsamples: 0-2.5 years after delivery and 2.5-5 years after delivery. We found significant differences concerning relationship/partner, education/educational level, employment status, means of subsistence, person in a position of trust, close friends and current contraceptive use. Apart from the domain "leisure time/hobbies" study participants were more satisfied compared with a population reference group of the same age. Our study did not support the common assumption that adolescent pregnancy may be a disadvantage for young women. In our study a considerable number does achieve a higher level of education. Furthermore we have shown that adolescents are more satisfied in certain areas of life compared with a population reference group.

Objective To assess and compare salivary periodontopathic bacteria between groups of Down syndrome and non-Down syndrome children and adolescents. Materials and Methods This study included a sample of 30 Down syndrome children and adolescents (G-DS) and 30 age- and sex-matched non-Down syndrome subjects (G-ND). Clinical examination determined the gingival bleeding index (GBI) and plaque index. Unstimulated whole saliva samples were collected from all participants. The fluorescence in situ hybridization (FISH) technique identified the presence and density of eight periodontopathic bacteria in saliva. The statistical analysis included chi-square and Mann-Whitney U tests. Results In the G-DS group, bleeding on probing was more frequent (p = 0.037) and higher densities of Campylobacter rectus (p = 0.013), Porphyromonas gingivalis (p = 0.025), Treponema denticola (p = 0.026), Fusobacterium nucleatum (p = 0.013), Prevotella intermedia (p = 0.001) and Prevotella nigrescens (p = 0.008) were observed. Besides, in the G-DS, the densities of bacteria from the orange complex were significantly higher in the age group 3–7 years for F. nucleatum (p = 0.029), P. intermedia (p = 0.001) and P. nigrescens (p = 0.006). C. rectus was higher in the age group 8–12 years (p = 0.045). Conclusion The results showed that children and adolescents with Down syndrome have higher susceptibility to periodontal disease and number of periodontopathic bacteria. PMID:27727287

Adolescent engagement in dangerous behaviors is associated with increased white matter maturity of frontal cortex.

PubMed

Berns, Gregory S; Moore, Sara; Capra, C Monica

2009-08-26

Myelination of white matter in the brain continues throughout adolescence and early adulthood. This cortical immaturity has been suggested as a potential cause of dangerous and impulsive behaviors in adolescence. We tested this hypothesis in a group of healthy adolescents, age 12-18 (N = 91), who underwent diffusion tensor imaging (DTI) to delineate cortical white matter tracts. As a measure of real-world risk taking, participants completed the Adolescent Risk Questionnaire (ARQ) which measures engagement in dangerous activities. After adjusting for age-related changes in both DTI and ARQ, engagement in dangerous behaviors was found to be positively correlated with fractional anisotropy and negatively correlated with transverse diffusivity in frontal white matter tracts, indicative of increased myelination and/or density of fibers (ages 14-18, N = 60). The direction of correlation suggests that rather than having immature cortices, adolescents who engage in dangerous activities have frontal white matter tracts that are more adult in form than their more conservative peers.

The aim of this research was to compare the levels of perceived health literacy among adolescents who do or do not participate in sports club activities. Organized sport club activities reach a high proportion of adolescents, and have the potential to contribute to the development of their health literacy. The cross-sectional data on health literacy among school children in Finland (aged 13 and 15, n=3852) were measured, as a part of the Health Behaviour in School-Aged Children (HBSC) study, using the Health Literacy for School-aged Children (HLSAC) instrument. Sports club participation and its association with health literacy were examined in relation to age, gender, family affluence, school achievement, and physical activity. The statistical analyses included cross-tabulation and the multilevel mixed-effects logistic regression analyses. Perceived health literacy was higher among adolescents who participated in sports club activities. This conclusion was valid for boys and girls, for both age groups, among those who were physically active 6-7 days a week, had at least moderate school achievement, and those who belonged to the middle or high affluence families. From the health literacy perspective, participation in sports club activities was especially beneficial for those having low or moderate school achievement level. The sports club setting may work towards equalizing health literacy differences related to school achievement. However, the clubs should ensure that access is available to as many adolescents as possible; by this means they may spread beneficial influences, supporting the development of health literacy among broader population groups.

This paper reports the geographical patterns and time trends of incidence and survival of Hodgkin's disease (HD) in children and adolescents in Europe over the period 1978-1997. Data on 4230 HD cases were gathered from 62 paediatric or general cancer registries in 19 European countries by the Automated Cancer Information System (ACCIS). European annual incidence rates in 1988-1997 were estimated at 5.8 per million in children (world age-standardised) and at 29.7 per million in adolescents, with higher rates in the East and South. Incidence rates increased steeply with age, while the male predominance, marked for the youngest children, vanished in the highest age groups. Over the period 1978-1997 incidence rates increased in age groups 10-14 years (+1% per year) and 15-19 years (+3.5% per year), mainly due to the nodular sclerosis subtype. Age and sex distribution of cases remained unchanged with time. The overall 5-year survival rate was higher in children (93%, 95% confidence interval (CI) 92-94) than in adolescents (89% (95% CI 87-91)) for the period 1988-1997. Five-year survival increased significantly in all regions from 87% to 93% in children and from 80% to 88% in adolescents between 1978-1982 and 1993-1997. In future, detailed documentation of cases in the cancer registries with respect to standardised diagnostic subtypes, stage of extension, and treatments, will help to refine interpretation of international and temporal variations in incidence and survival.

Data on awareness of adolescent's on the legal and social issues/acts related to reproductive health, especially in rural areas, are scarce. The aim of the present cross-sectional study is to assess the awareness level of legal and social issues related to reproductive health and its association with the various individual and family/household level characteristics. 650 adolescent girls in the age group of 15-19 years were interviewed with the help of pretested and semistructured questionnaire and focus group discussions were also conducted for qualitative findings in Chiraigaon block of district Varanasi. It was observed that 42.9% of the respondents were aware of legal age of marriage, 14.9% knew about the right age of childbearing. Dowry prohibition act and domestic violence act were known to 46% and 27% respondents, respectively, and only 2.6% were aware of medical termination of pregnancy act. Logistic regression analysis shows the significant effect of education on awareness of legal age of marriage, right age of childbearing, domestic violence, and dowry prohibition acts, which is also supported by qualitative findings. All the important legal issues/acts should be included in high school curriculum and female teachers should be involved in training program for adolescents. Role of mass media in creating awareness about these issues in their routine programs should be ascertained. Accredited Social Health Activist and Anganwadi workers should be aware of and include these issues/acts in adolescent meetings.

Objective: To analyze the prevalence and factors associated with the co-occurrence of health risk behaviors in adolescents. Methods: A cross-sectional study was performed with a sample of high school students from state public schools in Pernambuco, Brazil (n=4207, 14-19 years old). Data were obtained using a questionnaire. The co-occurrence of health risk behaviors was established based on the sum of five behavioral risk factors (low physical activity, sedentary behavior, low consumption of fruits/vegetables, alcohol consumption and tobacco use). The independent variables were gender, age group, time of day attending school, school size, maternal education, occupational status, skin color, geographic region and place of residence. Data were analyzed by ordinal logistic regression with proportional odds model. Results: Approximately 10% of adolescents were not exposed to health risk behaviors, while 58.5% reported being exposed to at least two health risk behaviors simultaneously. There was a higher likelihood of co-occurrence of health risk behaviors among adolescents in the older age group, with intermediate maternal education (9-11 years of schooling), and who reported living in the driest (semi-arid) region of the state of Pernambuco. Adolescents who reported having a job and living in rural areas had a lower likelihood of co-occurrence of risk behaviors. Conclusions: The findings suggest a high prevalence of co-occurrence of health risk behaviors in this group of adolescents, with a higher chance in five subgroups (older age, intermediate maternal education, the ones that reported not working, those living in urban areas and in the driest region of the state).

Skeletal robustness (cross-section size relative to length) is associated with stress fractures in adults, and appears to explain the high incidence of distal radius fractures in adolescents. However, little is known about the ontogeny of long bone robustness during the first three decades of life. Therefore, we explored the ontogeny of tibial, fibular, ulnar and radial robustness in a cross-sectional sample of 5 to 29year-old volunteers of both sexes. Peripheral quantitative computed tomography (pQCT) was used to evaluate cross-sections of the leg (4%, 14%, 38% and 66%), and forearm (4%, and 66%) in N=432 individuals. Robustness was evaluated as the total bone area divided by bone length. Differences between age-groups, sexes, and age-group×sex interactions were evaluated with ANOVA with Tukey's post hocs where appropriate. Most bone sites exhibited more robust bones in men than women (P<0.001 to 0.02), and in older age-groups than younger (P<0.001). Sex×age-group interaction was observed at the 66% and 38% tibia sites with robustness increasing more with age in men than in women (P=0.006 to 0.042). Post-hoc analyses indicated no sex differences prior to 13years-of-age, and notable exceptions to increasing robustness with age at the 4% radial and 66% tibial sites, which exhibited reduced robustness in age groups close to peak height velocity. In conclusion, the present results suggest that very little sexual dimorphism in long bone robustness exists prior to puberty, and that divergence occurs primarily after cessation of longitudinal growth. A period of relative diaphyseal slenderness was identified at age-groups coinciding with the adolescent growth spurt, which may be related to the relatively high incidence of frank and stress fracture in adolescents.

Adolescents are at a greater risk of being involved in traffic accidents than most other age groups, even before they start driving cars. This article aims to determine the factor structure of a self-report questionnaire measuring adolescent risky cycling behaviour, the ACBQ (Adolescent Cycling Behaviour Questionnaire). The questionnaire's structure was based on the widely used Driver Behaviour Questionnaire (DBQ). A sample of secondary school students (N = 1749; age range: 13-18 years) filled out the questionnaire. Factor analysis revealed a three-factor structure underlying the questionnaire, which was confirmed on two equally large portions of the entire sample. These three underlying factors were identified as errors, common violations and exceptional violations. The ACBQ is a useful instrument for measuring adolescents' risky cycling behaviour.

The present study aimed to investigate the longitudinal influence of physical education classes, extracurricular sports activities, and leisure satisfaction on aggressive behavior among South Korean adolescents. Data were drawn from the Korea Youth Panel Survey. We used latent growth curve modeling to explain the growth trajectory of adolescent aggressive behaviors and a multi-group analysis to investigate gender differences in aggressive behavior. The results indicated that adolescents' aggressive behavior significantly changed with age. There were significant gender-based differences in the level of and changes in aggressive behavior over time. Both extracurricular sports activities and leisure satisfaction had significant influences on the changes in adolescents' aggressive behavior with age, whereas physical education classes did not.

Social phobia typically develops during the adolescent years, yet no nationally representative studies in the United States have examined the rates and features of this condition among youth in this age range. The objectives of this investigation were to: (1) present the lifetime prevalence, sociodemographic and clinical correlates, and comorbidity of social phobia in a large, nationally representative sample of U.S. adolescents; and (2) examine differences in the rates and features of social phobia across the proposed DSM-5 social phobia subtypes. The National Comorbidity Survey Replication-Adolescent Supplement is a nationally representative face-to-face survey of 10,123 adolescents 13 to 18 years of age in the continental United States. Approximately 9% of adolescents met criteria for any social phobia in their lifetime. Of these adolescents, 55.8% were affected with the generalized subtype and 44.2% exhibited nongeneralized social phobia. Only 0.7% met criteria for the proposed DSM-5 performance-only subtype. Generalized social phobia was more common among female adolescents and risk for this subtype increased with age. Adolescents with generalized social phobia also had a younger age of onset, higher levels of disability and clinical severity, and a greater degree of comorbidity relative to adolescents with nongeneralized forms of the disorder. This study indicates that social phobia is a highly prevalent, persistent, and impairing psychiatric disorder among adolescent youth. Results of this study also provide evidence for the clinical utility of the generalized subtype and highlight the importance of considering the heterogeneity of social phobia in this age group.

Objectives: Adolescents in Africa have low HIV testing rates. Better understanding of adolescent, provider, and caregiver experiences in high-burden countries such as Kenya could improve adolescent HIV testing programs. Design: We conducted 16 qualitative interviews with HIV-positive and HIV-negative adolescents (13–18 years) and six focus group discussions with Healthcare workers (HCWs) and caregivers of adolescents in Nairobi, Kenya. Methods: Semi-structured interviews and focus groups were recorded and transcribed. Analysis employed a modified constant comparative approach to triangulate findings and identify themes influencing testing experiences and practices. Results: All groups identified that supportive interactions during testing were essential to the adolescent's positive testing experience. HCWs were a primary source of support during testing. HCWs who acted respectful and informed helped adolescents accept results, link to care, or return for repeat testing, whereas HCWs who acted dismissive or judgmental discouraged adolescent testing. Caregivers universally supported adolescent testing, including testing with the adolescent to demonstrate support. Caregivers relied on HCWs to inform and encourage adolescents. Although peers played less significant roles during testing, all groups agreed that school-based outreach could increase peer demand and counteract stigma. All groups recognized tensions around adolescent autonomy in the absence of clear consent guidelines. Adolescents valued support people during testing but wanted autonomy over testing and disclosure decisions. HCWs felt pressured to defer consent to caregivers. Caregivers wanted to know results regardless of adolescents’ wishes. Conclusion: Findings indicate that strengthening HCW, caregiver, and peer capacities to support adolescents while respecting their autonomy may facilitate attaining ‘90-90-90’ targets for adolescents.

This study investigated the effect of a macrobiotic (vegan-type) diet, low in calcium and vitamin D, consumed in early life, on bone mineral during adolescence. Bone mineral content (BMC) and bone area were measured in 195 adolescents (103 girls, 92 boys) aged 9-15 years, using dual-energy X-ray absorptiometry. Ninety-three adolescents (43 girls, 50 boys) had followed a macrobiotic diet in childhood, and 102 (60 girls, 42 boys) were control subjects. After adjustment for bone area, weight, height, percent body lean, age, and puberty, BMC was significantly lower in macrobiotic subjects, in boys and girls, respectively, at the whole body, -3.4% and -2.5%, spine, -8.5% and -5.0%, femoral neck, -8.0% and -8.2%, midshaft radius, -6.8% and -5.6%, and also in girls, at the trochanter, -5.8% (p < 0.05). No group differences were observed at the wrist. Group differences were not explained by current calcium adjusted bone mass at age 9-15 years, observations which may hold important implications for fracture risk in later life.

PubMed

DiFranza, J R; Coleman, M

2001-12-01

To determine how youths obtain tobacco in communities with strong enforcement of tobacco sales laws. Ten communities in Massachusetts with merchant compliance rates at or above 90%. Paper surveys and focus group discussions with 68 adolescent smokers. Parents and friends are the primary sources of tobacco for new smokers. When stealing from parents can no longer satisfy the need for cigarettes, young adolescents ask strangers to buy them tobacco. For high school age smokers, teenage store clerks are a major source. Teenage clerks sell to other teenagers, steal tobacco, and help their friends steal from their employers. Friends who are 18 years of age or over are a second major source for older adolescents. Parents often purchase tobacco for older adolescents. Recommended actions include raising the minimum age for the purchase of tobacco to 21 years, and prohibiting individuals less than 21 years of age from selling tobacco.

2017-02-01

Personality features have been correlated with suicidal behaviors in recent decades. Given its neurobiological background, Cloninger's model of personality, the Temperament and Character Inventory (TCI), may help to identify the maternal and paternal personality dimensions associated with adolescent suicide attempts. The present study is the first that specifically compares the temperament and character profiles of both mothers and fathers of the adolescent suicide attempters with a control group, by considering the influence of demographic and clinical factors. The study group comprised 117 parents of 71 adolescent suicide attempters and 119 parents of 71 age- and gender-matched adolescents without a suicide attempt included as a control group. The TCI and Brief Symptom Inventory (BSI) were applied to the parents in both groups. Logistic regression analysis, which was performed to adjust confounding factors, demonstrated significantly higher scores for harm avoidance among the mothers and lower scores of self-directedness among the fathers of the adolescent suicide attempters. New psychotherapeutic modalities considering the high-risk parental personality traits would be beneficial to support parent-adolescent relationships and may have a preventative effect on adolescent suicide.

Assessment of Adolescent Neurotoxicity: Rationale and Methodological Considerations

PubMed Central

Spear, Linda Patia

2007-01-01

This introduction to the special issue of Neurotoxicology and Teratology on “Risk of neurobehavioral toxicity in adolescence” begins by broadly considering the ontogeny and phylogeny of adolescence, and the potential value of animal models of adolescence. Major findings from the emerging neuroscience of adolescence are then highlighted to establish the importance of studies of adolescent neurotoxicity. A variety of methodological issues that are of particular relevance to adolescent exposures are then discussed. These include consideration of pharmacokinetic factors, inclusion of other-aged comparison group(s), and issues involving timing, route of administration, and exposure-induced alterations in growth rate. Despite such methodological challenges, research to determine whether adolescence is a time of increased vulnerability (or greater resiliency) to specific drugs and environmental toxicants is progressing rapidly, as exemplified by the work presented in the articles of this special issue.

Autism spectrum disorders (ASD) are characterised by social and communication difficulties in day-to-day life, including problems in recognising emotions. However, experimental investigations of emotion recognition ability in ASD have been equivocal, hampered by small sample sizes, narrow IQ range and over-focus on the visual modality. We tested 99 adolescents (mean age 15;6 years, mean IQ 85) with an ASD and 57 adolescents without an ASD (mean age 15;6 years, mean IQ 88) on a facial emotion recognition task and two vocal emotion recognition tasks (one verbal; one non-verbal). Recognition of happiness, sadness, fear, anger, surprise and disgust were tested. Using structural equation modelling, we conceptualised emotion recognition ability as a multimodal construct, measured by the three tasks. We examined how the mean levels of recognition of the six emotions differed by group (ASD vs. non-ASD) and IQ (≥ 80 vs. < 80). We found no evidence of a fundamental emotion recognition deficit in the ASD group and analysis of error patterns suggested that the ASD group were vulnerable to the same pattern of confusions between emotions as the non-ASD group. However, recognition ability was significantly impaired in the ASD group for surprise. IQ had a strong and significant effect on performance for the recognition of all six emotions, with higher IQ adolescents outperforming lower IQ adolescents. The findings do not suggest a fundamental difficulty with the recognition of basic emotions in adolescents with ASD. © 2010 The Authors.

To evaluate the self-esteem and quality of life in adolescents with extreme obesity before and one year after laparoscopic sleeve gastrectomy as obesity is a major challenging medical problem, not only in adults but also in children and adolescents in Saudi Arabia. In a prospective cohort study, 32 adolescents (aged 13-17 years) with extreme obesity (Group 1) presenting for laparoscopic sleeve gastrectomy (LSG) were compared with 32 matched, healthy, nonobese adolescents (aged 14-17 years) (Group 2) with regards to self-esteem and quality of life. Assessment was done using the Rosenberg Self-Esteem Scale and Pediatric Quality of Life Inventory version 4.0 (self- and parent report), respectively. Body mass index (BMI) Z scores were calculated for both groups. We found significantly poor self-esteem and impairment in all domains of quality of life (self- and parent report) in Group 1 compared with Group 2 (P<.001). Self esteem and quality of life (self- and parent reports) significantly improved 1 year after LSG (P<.001), and the weight loss induced by LSG, reflected by a decrease in BMI Z scores, was a significant predictor for the improvement in self-esteem (R2=0.28 and P=.003) and quality of life (R(2)=0.67 and P<.001). LSG was found to be a safe and effective operation in adolescents with extreme obesity: LSG leads to weight loss, with subsequent improvement in self-esteem and quality of life.

Alcohol Binge Drinking and Executive Functioning during Adolescent Brain Development.

Gil-Hernandez, Soledad; Mateos, Patricia; Porras, Claudia; Garcia-Gomez, Raquel; Navarro, Enrique; Garcia-Moreno, Luis M

2017-01-01

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

Objective. To compare the clinical profiles in newborns of adolescent and non-adolescent mothers. Materials and Methods. Comparative cross-sectional study. Newborns selected by cluster sampling registered in the hospital. Two groups were formed according to the mother's age: adolescent and non-adolescent. The clinical profile was evaluated with: weight, length, Apgar score, gestational age, and presence of neonatal pathology. For the comparison between proportions, we used chi-squared test and student´s t-test between the mean. Results. Of the 2,155 clinical profiles of newborns analyzed, 819 (38%) were newborns of adolescent mothers and 1,336 (62%) of non-adolescent mothers. Differences between birth weight groups 2,859 ± 459 vs. 3,265 ± 486 grams (p = 0.000), male gender 518 (63%) vs. 725 (54%) female (p = 0.000); intrauterine growth restriction in full-term newborns 62 (7.5%) vs. 66 (4.9%) (p = 0.012); prematurity 171 (21%) vs. 213 (16%) (p = 0.003). Factors that favor the alteration of clinical profiles in newborns: adolescent mother OR: 1.58 (1.99-2.99), male gender OR: 1.80 (1.50-2.17), neonatal pathology OR: 3.73 (2.50-5.30), association of low birth weight in newborns of adolescent mothers OR: 2.4 (1.72-3.42). Conclusion. We found a high frequency of observing in newborns of adolescent mothers greater risk of prematurity, intrauterine growth restriction, and neonatal pathology. No differences were seen in length and Apgar score.

Is adolescence a critical period for learning formal thinking skills? A case study investigating the development of formal thinking skills in a short-term inquiry-based intervention program

NASA Astrophysics Data System (ADS)

Towne, Forrest S.

Current domestic and international comparative studies of student achievement in science are demonstrating that the U.S. needs to improve science education if it wants to remain competitive in the global economy. One of the causes of the poor performance of U.S. science education is the lack of students who have developed the formal thinking skills that are necessary to obtain scientific literacy. Previous studies have demonstrated that formal thinking skills can be taught to adolescents, however only 25% of incoming college freshman have these necessary skills. There is some evidence that adolescence (girls aged 11-13, boys aged 12-14) is a critical period where students must learn formal thinking skills, similar to the critical period that exists for young children learning languages. It is not known whether it is more difficult for students to learn formal thinking skills either prior to or following adolescence. The purpose of this quantitative case study is to determine whether adolescence is a critical period for students to learn formal thinking skills. The study also investigates whether a formal thinking skills focused program can improve students' intelligence. In this study 32 students who had not developed any formal thinking skills, ranging in age from 10-16, underwent an intensive four-week, inquiry-based, formal thinking skill intervention program that focused on two formal thinking skills: (1) the ability to control and exclude variables; and (2) the ability to manipulate ratios and proportionalities. The students undergoing the training were matched with control students by age, gender, formal thinking skill ability, and intelligence. The control group attended their traditional science course during the intervention periods. The results of the study showed that the intervention program was successful in developing students' formal thinking skills. The pre-adolescents (males, age 10-11, females, age 10) were unable to learn formal thinking skills. The data indicated that there is not a significant difference between adolescents and post-adolescents (up to 16-years-old) ability to learn formal thinking skills. Both groups (adolescent and post-adolescent) showed improvement in their formal thinking skill ability after the intervention. The intervention also demonstrated evidence of improving students' intelligence scores.

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

A mental health advantage has been observed among adolescents in urban areas. This prospective study tests whether cultural integration measured by cross-cultural friendships explains a mental health advantage for adolescents. A prospective cohort of adolescents was recruited from 51 secondary schools in 10 London boroughs. Cultural identity was assessed by friendship choices within and across ethnic groups. Cultural integration is one of four categories of cultural identity. Using gender-specific linear-mixed models we tested whether cultural integration explained a mental health advantage, and whether gender and age were influential. Demographic and other relevant factors, such as ethnic group, socio-economic status, family structure, parenting styles and perceived racism were also measured and entered into the models. Mental health was measured by the Strengths and Difficulties Questionnaire as a 'total difficulties score' and by classification as a 'probable clinical case'. A total of 6643 pupils in first and second years of secondary school (ages 11-13 years) took part in the baseline survey (2003/04) and 4785 took part in the follow-up survey in 2005-06. Overall mental health improved with age, more so in male rather than female students. Cultural integration (friendships with own and other ethnic groups) was associated with the lowest levels of mental health problems especially among male students. This effect was sustained irrespective of age, ethnicity and other potential explanatory variables. There was a mental health advantage among specific ethnic groups: Black Caribbean and Black African male students (Nigerian/Ghanaian origin) and female Indian students. This was not fully explained by cultural integration, although cultural integration was independently associated with better mental health. Cultural integration was associated with better mental health, independent of the mental health advantage found among specific ethnic groups: Black Caribbean and some Black African male students and female Indian students.

Brazilian jiu-jitsu is characterized by musculoskeletal disorders and high occurrence of sports injuries. The present study was aimed to analyze some internal factors, as well as to describe occurrence and characteristics of retrospective musculoskeletal injuries in different age groups of Brazilian jiu-jitsu practitioners. One hundred ninety-three Brazilian jiu-jitsu practitioners, which were divided into three age groups: Adolescent, Adult, and Master. Besides anthropometric characterization, standard clinical tests were conducted to analyze the global and segmental joint flexibility, lumbar spine range of motion, and handgrip strength. Sports injury occurrence and total physical activity were obtained from an adapted morbidity survey and International Physical Activity Questionnaire - Short Form (IPAQ-SF), respectively. A total of 247 cases of retrospective injuries was registered (1.27 injury/ participant). Occurrence of rectus femoral muscle retraction in the right leg was increased within Master. Adult and Master have exhibited higher occurrence of sports injuries than Adolescent group ( p  < 0.05). Joint injuries were the most common sports-related injuries by all Brazilian jiu-jitsu practitioners. While female gender and exposure time constituted the most predictive variables for sports injury occurrence in Adolescent, graduation level was more associated with sports injuries occurrence in Adult. Joint injuries derived from combat demands were the main sports injury in all age categories of Brazilian jiu-jitsu. Master subjects presented a higher occurrence of clinical changes and retrospective musculoskeletal injuries in relation to other age groups. Female gender and exposure time constituted the main predictive factors in adolescent subjects, while graduation category was more directly associated with retrospective injury onset in the Adult group.

Data regarding the use of technology to improve adolescent knowledge on vaccines are scarce. The main aim of this study was to evaluate whether different web-based educational programmes for adolescents might increase their vaccination coverage. Overall, 917 unvaccinated adolescents (389 males, 42.4%; mean age ± standard deviation, 14.0 ± 2.2 years) were randomized 1:1:1 into the following groups: no intervention (n = 334), website educational program only (n = 281), or website plus face to face lesson (n = 302) groups. The use of the website plus the lesson significantly increased the overall knowledge of various aspects of vaccine-preventable disease and reduced the fear of vaccines (p < 0.001). A significant increase in vaccination coverage was observed for tetanus, diphtheria, acellular pertussis and conjugated meningococcal ACYW vaccines in the 2 groups using the website (p < 0.001), and better results were observed in the group that had also received the lesson; in this last group, significant results were observed in the increase in vaccination coverage for meningococcal B vaccine (p < 0.001). Overall, the majority of the participants liked the experience of the website, although they considered it important to further discuss vaccines with parents, experts and teachers. This study is the first to evaluate website based education of adolescents while considering all of the vaccines recommended for this age group. Our results demonstrate the possibility of increasing vaccination coverage by using a website based educational program with tailored information. However, to be most effective, this program should be supplemented with face-to-face discussions of vaccines at school and at home. Thus, specific education should also include teachers and parents so that they will be prepared to discuss with adolescents what is true and false in the vaccination field.

To identify which feasible obesity and insulin resistance (IR) screening tools are most strongly associated in adolescents by using a nationally representative sample. Adolescents aged 12.0 to 18.9 years who were participating in the National Health and Nutrition Examination Survey (NHANES) (n=3584) and who were measured for height, weight, waist circumference (WC), triceps and subscapular skinfold thickness, glycated hemoglobin, fasting glucose (FG) and fasting insulin (FI) level were included. Adolescents were split by gender and grouped by body mass index (BMI) percentile. Age- and gender-specific classifications were constructed for each obesity screening tool measure to account for growth and maturation. General linear models were used to establish groups objectively for analysis based on when IR began to increase. Additional general linear models were used to identify when IR significantly increased for each IR measure as obesity group increased and to identify the variance accounted for among each obesity-IR screening tool relationship. As the obesity group increased, homeostasis model assessment-insulin resistance (HOMA-IR) and FI significantly increased, while FG increased only (above the referent) in groups with BMI percentiles ≥95.0, and glycated hemoglobin level did not vary across obesity groups. The most strongly associated screening tools were WC and FI in boys (R(2)=0.253) and girls (R(2)=0.257). FI had the strongest association with all of the obesity measures. BMI associations were slightly weaker than WC in each in relation to IR. Our findings show that WC and FI are the most strongly associated obesity and IR screening tool measures in adolescents. These feasible screening tools should be utilized in screening practices for at-risk adolescents. Copyright © 2015 Canadian Diabetes Association. Published by Elsevier Inc. All rights reserved.

ABSTRACT OBJECTIVE To describe food and macronutrient intake profile and estimate the prevalence of inadequate micronutrient intake of Brazilian adolescents. METHODS Data from 71,791 adolescents aged from 12 to 17 years were evaluated in the 2013-2014 Brazilian Study of Cardiovascular Risks in Adolescents (ERICA). Food intake was estimated using 24-hour dietary recall (24-HDR). A second 24-HDR was collected in a subsample of the adolescents to estimate within-person variability and calculate the usual individual intake. The prevalence of food/food group intake reported by the adolescents was also estimated. For sodium, the prevalence of inadequate intake was estimated based on the Tolerable Upper Intake Level (UL). The Estimated Average Requirement (EAR) method used as cutoff was applied to estimate the prevalence of inadequate nutrient intake. All the analyses were stratified according to sex, age group and Brazilian macro-regions. All statistical analyses accounted for the sample weight and the complex sampling design. RESULTS Rice, beans and other legume, juice and fruit drinks, breads and meat were the most consumed foods among the adolescents. The average energy intake ranged from 2,036 kcal (girls aged from 12 to 13 years) to 2,582 kcal (boy aged from14 to 17 years). Saturated fat and free sugar intake were above the maximum limit recommended (< 10.0%). Vitamins A and E, and calcium were the micronutrients with the highest prevalence of inadequate intake (> 50.0%). Sodium intake was above the UL for more than 80.0% of the adolescents. CONCLUSIONS The diets of Brazilian adolescents were characterized by the intake of traditional Brazilian food, such as rice and beans, as well as by high intake of sugar through sweetened beverages and processed foods. This food pattern was associated with an excessive intake of sodium, saturated fatty acids and free sugar. PMID:26910551

The purpose of this study was to examine the effect of starup circuit exercise program on derivatives reactive oxygen metabolite (d-ROM) and biological antioxidant potential (BAP) levels and physical fitness of adolescents with intellectual disabilities, and to sugesst exercise programs to promote the health and physical development of such adolescents. Twelve students with intellectual disabilities were divided into two groups; circuit exercise group (CE group: n=6; age, 14.83±0.98 years; height, 163.83±5.78 cm; body mass, 67.08±3.32 kg; %Fat, 25.68±2.42), control group (CON group: n=6; age: 15.00±0.63 years; height, 162.33±4.41 cm; body mass, 67.50±3.62 kg; %Fat, 26.96±2.06). The CE group performed the CE program 4 times a week over a 12-week period. The CON group maintained their activities of daily living. The following were measured before and after intervention: physical fitness by before and after the completion of the training programm, and were measured and blood samples were assessed. The results of the study indicate that the 12-week CE program increased significantly physical fitness ( P <0.05). Furthermore, This study proved that the CE program improved physical fitness, and reduced the d-ROM levels, and increased the BAP levels of the adolescents with intellectual disabilities. Therefore, it may enhance the health and physical development of adolescents boys with intellectual disabilities.

Objectives. To investigate self-reported health-related quality of life (HrQoL) in children and adolescents with chronic medical conditions compared with siblings/peers. Methods. Group 1 (6 treatment centers) consisted of 74 children/adolescents aged 8–16 years with hereditary bleeding disorders (HBD), 12 siblings, and 34 peers. Group 2 (one treatment center) consisted of 70 children/adolescents with stroke/transient ischemic attack, 14 siblings, and 72 peers. HrQoL was assessed with the “revised KINDer Lebensqualitätsfragebogen” (KINDL-R) questionnaire. Multivariate analyses within groups were done by one-way ANOVA and post hoc pairwise single comparisons by Student's t-tests. Adjusted pairwise comparisons were done by hierarchical linear regressions with individuals nested within treatment centers (group 1) and by linear regressions (group 2), respectively. Results. No differences were found in multivariate analyses of self-reported HrQoL in group 1, while in group 2 differences occurred in overall wellbeing and all subdimensions. These differences were due to differences between patients and peers. After adjusting for age, gender, number of siblings, and treatment center these differences persisted regarding self-worth (p = .0040) and friend-related wellbeing (p < .001). Conclusions. In children with HBD, HrQoL was comparable to siblings and peers. In children with stroke/TIA HrQoL was comparable to siblings while peers, independently of relevant confounder, showed better self-worth and friend-related wellbeing. PMID:27294108

This longitudinal study explored family functioning and relationship quality for adolescents with severe anorexia nervosa (AN). An important outcome given healthy family functioning supports effective adolescent development. Fifty-four female adolescents and their parents, treated with family-based treatment after inpatient admission, and 49 non-clinical age-matched adolescents and their parents were compared at assessment and 6 months after session 20. At baseline, AN group mothers and fathers reported poorer family function. AN adolescents were notably similar to controls, reporting poorer function in only one domain. There were no changes for adolescents, an improvement for mothers in the AN group, but an increase in perceived impairment for fathers in both groups, with AN fathers more affected. The similarity in adolescent reports and the increase for fathers over time may indicate that normal adolescent family processes occur even in the midst of serious illness. There is a need to provide intervention to ameliorate the impact of treatment on parents. Copyright © 2017 John Wiley & Sons, Ltd and Eating Disorders Association.

BACKGROUND Patch testing is an efficient method to identify the allergen responsible for allergic contact dermatitis. OBJECTIVE To evaluate the results of patch tests in children and adolescents comparing these two age groups' results. METHODS Cross-sectional study to assess patch test results of 125 children and adolescents aged 1-19 years, with suspected allergic contact dermatitis, in a dermatology clinic in Brazil. Two Brazilian standardized series were used. RESULTS Seventy four (59.2%) patients had "at least one positive reaction" to the patch test. Among these positive tests, 77.0% were deemed relevant. The most frequent allergens were nickel (36.8%), thimerosal (18.4%), tosylamide formaldehyde resin (6.8%), neomycin (6.4%), cobalt (4.0%) and fragrance mix I (4.0%). The most frequent positive tests came from adolescents (p=0.0014) and females (p=0.0002). There was no relevant statistical difference concerning contact sensitizations among patients with or without atopic history. However, there were significant differences regarding sensitization to nickel (p=0.029) and thimerosal (p=0.042) between the two age groups under study, while adolescents were the most affected. CONCLUSION Nickel and fragrances were the only positive (and relevant) allergens in children. Nickel and tosylamide formaldehyde resin were the most frequent and relevant allergens among adolescents.

Perceived safer than tobacco cigarettes, prevalence of electronic cigarette (e-cigarette) use is increasing. Analyses of cartridges suggest that e-cigarettes may pose health risks. In light of increased use and the potential for consequences, we searched Google Scholar and Pubmed in July of 2013 using keywords, such as e-cigarette and vaping, to compare differences and similarities in prevalence and correlates of e-cigarette use among adolescents (grades 6-12) versus adults (aged ≥18 years). Twenty-one studies focused on e-cigarette use. Ever-use increased among various age groups. In 2011, ever-use was highest among young adults (college students and those aged 20-28; 4.9%-7.0%), followed by adults (aged ≥18; 0.6%-6.2%), and adolescents (grades 6-12 and aged 11-19; <1%-3.3%). However, in 2012 adolescent ever-use increased to 6.8% and, among high school students, went as high as 10.0%. While the identified common correlate of e-cigarette use was a history of cigarette smoking, a notable proportion of adolescents and young adults who never smoked cigarettes had ever-used e-cigarettes. E-cigarette use was not consistently associated with attempting to quit tobacco among young adults. Adults most often reported e-cigarettes as a substitute for tobacco, although not always to quit. Reviewed studies showed a somewhat different pattern of e-cigarette use among young people (new e-cigarette users who had never used tobacco) versus adults (former or current tobacco users). Research is needed to better characterize prevalences, use correlates, and motives of use in different population groups, including how adolescent and young adult experimentation with e-cigarettes relates to other types of substance use behaviors.

Team handball is associated with a high risk of severe knee injury that needs to be reduced, particularly at the youth level. The purpose of this study was to show how an injury-prevention programme effectively reduces severe knee injury in adolescent team handball players. Of 23 adolescent handball teams of both sexes, 13 were randomly allocated into the intervention group (168 players) and 10 into the control group (111 players). Players of the intervention group regularly participated in an injury-prevention programme for one season. Handball exposure and sustained injuries were documented for both groups on a monthly basis. The primary outcome parameter of the injury-prevention programme was the incidence of severe knee injury. Of the 279 included players, 68 (24%) sustained 82 injuries yielding an overall incidence of 1.85 injuries per 1000 h handball exposure (intervention group: 50 injuries/incidence: 1.90/1000 h; control group: 32 injuries/incidence: 1.78/1000 h). Knee injury was the second most frequent injury in adolescent team handball. The primary outcome parameter, severe knee injury occurred significantly more often in the control group [mean age (SD) 15.1 (1.0), injury incidence 0.33/1000 h] than in the intervention group [mean age (SD) 14.9 (0.9), injury incidence 0.04/1000 h]. The odds ratio was 0.11 (95% CI 0.01-0.90), p = 0.019. Other injuries to the lower extremities showed no significant difference between the two groups. Frequent neuromuscular exercises prevent severe knee injury in adolescent team handball players and should thus be included in the practical routine as well as in the education of team coaches.

Purpose Prospective longitudinal research is needed to examine associations between bullying behaviors and trajectories of suicidal ideation and behavior and overall functional impairment. The specific aims of the present study are to: (1) characterize differences in baseline functioning between acutely suicidal adolescents who are classified into bullying perpetrator and non-bully groups and (2) examine the 1-year trajectories of these two groups of adolescents. Method Participants were 433 psychiatrically hospitalized suicidal adolescents (72% female), ages 13 to 17 years. Participants reported suicidal ideation, depression, anxiety, substance use, adaptive functioning, and bullying behavior. Six items from the Youth Self-Report were used to classify adolescents into bullying perpetrator (n = 54) and non-bully (n = 379) groups. Follow-up assessments were conducted at 6 weeks, 3 months, 6 months, and 12 months. Results At hospitalization, adolescents in the bully group reported significantly higher levels of suicidal ideation, substance use, and functional impairment. Suicidal ideation differences remitted at six weeks. The elevated functional impairment of the bullying perpetrator group persisted across the 12-month period. Conclusion Adolescents who met bullying perpetrator group criteria were characterized by more severe suicidal ideation and higher levels of proximal risk factors for suicide. Bullying behavior was not stable over time but was associated with elevated suicide risk when present. These findings highlight the importance of specifically assessing for and targeting bullying behavior at multiple time points when treating suicidal adolescents. PMID:23790201

This study showed a retrospective analysis of the etiology, incidence and treatment of maxillofacial injuries in a pediatric and adolescent population of the State of Sao Paulo. We analyzed 2986 medical records of victims of facial trauma under 18 years, treated between 1999 and 2008 by the Department of Oral and Maxillofacial Surgery, Piracicaba Dental School, University of Campinas, Sao Paulo - Brazil. During this period, 757 patients under 18 were victims of maxillofacial trauma, of which, 112 patients had 139 lines of fracture in the mandible. The most affected age group were male adolescents. The bicycle accidents constituted the main etiology (34.82%). The conservative treatment was used in 51% of cases, and 49% received surgical treatment. Only 5 cases of postoperative complications were identified. The incidence of trauma and mandible fractures in pediatric and adolescent patients was high in the area of study. Bicycle accidents and falls being the main etiological factors. The group of adolescents was most affected. The conservative and surgical treatment was used almost in the same proportion.

This study examined national trends in 12-month prevalence of major depressive episodes (MDEs) in adolescents and young adults overall and in different sociodemographic groups, as well as trends in depression treatment between 2005 and 2014. Data were drawn from the National Surveys on Drug Use and Health for 2005 to 2014, which are annual cross-sectional surveys of the US general population. Participants included 172 495 adolescents aged 12 to 17 and 178 755 adults aged 18 to 25. Time trends in 12-month prevalence of MDEs were examined overall and in different subgroups, as were time trends in the use of treatment services. The 12-month prevalence of MDEs increased from 8.7% in 2005 to 11.3% in 2014 in adolescents and from 8.8% to 9.6% in young adults (both P < .001). The increase was larger and statistically significant only in the age range of 12 to 20 years. The trends remained significant after adjustment for substance use disorders and sociodemographic factors. Mental health care contacts overall did not change over time; however, the use of specialty mental health providers increased in adolescents and young adults, and the use of prescription medications and inpatient hospitalizations increased in adolescents. The prevalence of depression in adolescents and young adults has increased in recent years. In the context of little change in mental health treatments, trends in prevalence translate into a growing number of young people with untreated depression. The findings call for renewed efforts to expand service capacity to best meet the mental health care needs of this age group. Copyright © 2016 by the American Academy of Pediatrics.

To study the bias in seeking medical care for female child in various age groups from birth to adolescence. It is a retrospective analysis of the hospital records for the period January 2010 through December 2012. The sex ratio was calculated for different age groups including newborns delivered, patients attending OPD (0-12 y), children attending immunization centre (0-5 y), patients admitted in pediatric wards segregated in different age groups i.e., < 1 y, 1-4 y, 5-9 y and 10-14 y. Chi square test was used to find out if there was any variation in the sex ratio of patients attending the hospital against the sex ratio in the community. The mean sex ratio of patients (0-12 y) attending the pediatric OPD was 726 which is significantly lower than the sex ratio in the community (p < 0.00001). The sex ratio of patients (0-5 y) visiting immunization centre (846) was also significantly lower than sex ratio in the community (p = 0.0343). Among children delivered in the hospital mean sex ratio at birth was 934 against a sex ratio of 920 at birth in the reference population. The sex ratio of admitted patients was significantly lower in age groups <1 y (617, p value < 0.00001), 1-4 y (665, p value <0.00001), 5-9 y (665, p value <0.05). But the sex ratio improved for inpatients in the age group 10-14 y (794, p = 0.08). There is a strong bias against females for seeking medical attention both for outpatient and inpatient care. The bias is more for females in younger age groups as compared to adolescents.

Individuals with autism spectrum disorders (ASD) have aberrant neural activity during semantic judgments. We aimed to examine age-dependent neural correlates of semantic processing in boys with ASD as compared to typically developing boys (TD). We used functional MRI to investigate 37 boys with ASD (mean age = 13.3 years, standard deviation = 2.4) and 35 age-, sex-, Intelligence quotient (IQ)- and handedness-matched TD boys (mean age = 13.3 years, standard deviation = 2.7) from age 8 to 18 years. Participants had to indicate whether pairs of Chinese characters presented visually were related in meaning. Group (ASD, TD) × Age (Old, Young) ANOVA was used to examine the difference of age-related changes. Direct comparisons between the adolescent group and the child group were also performed. The behavioral results showed that the ASD group had lower accuracy in the related condition relative to the TD group. The neuroimaging results showed greater activation in the cuneus and less activation in the left inferior frontal gyrus in boys with ASD than TD boys. Children with ASD produced greater activation in the cuneus than TD children. Adolescents with ASD showed reduced left IFG activation as compared to TD adolescents. Our findings suggest that TD boys may engage more in higher-level processing of retrieving or selecting semantic features while boys with ASD may rely more on lower-level visual processing during semantic judgments. The findings imply different functional organizations of the semantic system between the two groups.

2013-04-01

Past research has shown that adolescent peer groups make a significant contribution to shaping behavior but less is known about the role of peer groups in adolescent dating relationships. This longitudinal study examined the contribution of aggressive peer group norms on relationship quality and dating violence among dating adolescents. At the beginning of the school year (T1) and 6 months later (T2), participants (n = 1,070; M(age) = 15.45; 49 % Female) provided self-reports of attitudes towards aggression, and physically- and relationally-aggressive behaviors. Peer groups were identified using a peer-nomination technique and aggressive behaviors and attitudes were averaged across peer groups. Participants with dating experience (n = 598) reported on the frequency of their experience with dating violence (both as a victim and perpetrator). Multilevel analyses indicated that peer group relational aggression at T1 positively predicted dating abuse victimization and perpetration, and negatively predicted relationship quality at T2, beyond individual predictions. An unexpected finding was that membership in physically aggressive peer groups at T1 was associated positively with relationship quality at T2. Results point to the importance of the peer group in shaping adolescent dating experiences.

Background The implementation of an Internet option in an existing public health interview survey using a mixed-mode design is attractive because of lower costs and faster data availability. Additionally, mixed-mode surveys can increase response rates and improve sample composition. However, mixed-mode designs can increase the risk of measurement error (mode effects). Objective This study aimed to determine whether the prevalence rates or mean values of self- and parent-reported health indicators for children and adolescents aged 0-17 years differ between self-administered paper-based questionnaires (SAQ-paper) and self-administered Web-based questionnaires (SAQ-Web), as well as between a single-mode control group and different mixed-mode groups. Methods Data were collected for a methodological pilot of the third wave of the "German Health Interview and Examination Survey for Children and Adolescents". Questionnaires were completed by parents or adolescents. A population-based sample of 11,140 children and adolescents aged 0-17 years was randomly allocated to 4 survey designs—a single-mode control group with paper-and-pencil questionnaires only (n=970 parents, n=343 adolescents)—and 3 mixed-mode designs, all of which offered Web-based questionnaire options. In the concurrent mixed-mode design, both questionnaires were offered at the same time (n=946 parents, n=290 adolescents); in the sequential mixed-mode design, the SAQ-Web was sent first, followed by the paper questionnaire along with a reminder (n=854 parents, n=269 adolescents); and in the preselect mixed-mode design, both options were offered and the respondents were asked to request the desired type of questionnaire (n=698 parents, n=292 adolescents). In total, 3468 questionnaires of parents of children aged 0-17 years (SAQ-Web: n=708; SAQ-paper: n=2760) and 1194 questionnaires of adolescents aged 11-17 years (SAQ-Web: n=299; SAQ-paper: n=895) were analyzed. Sociodemographic characteristics and a broad range of health indicators for children and adolescents were compared by survey design and data collection mode by calculating predictive margins from regression models. Results There were no statistically significant differences in sociodemographic characteristics or health indicators between the single-mode control group and any of the mixed-mode survey designs. Differences in sociodemographic characteristics between SAQ-Web and SAQ-paper were found. Web respondents were more likely to be male, have higher levels of education, and higher household income compared with paper respondents. After adjusting for sociodemographic characteristics, only one of the 38 analyzed health indicators showed different prevalence rates between the data collection modes, with a higher prevalence rate for lifetime alcohol consumption among the online-responding adolescents (P<.001). Conclusions These results suggest that mode bias is limited in health interview surveys for children and adolescents using a mixed-mode design with Web-based and paper questionnaires. PMID:29506967

The objective of this study was twofold: First, to conduct a confirmatory factor analysis of the Portuguese versions of Disabkids-10; and second, to examine potential differences in factor structures between age-groups, genders, and informants. The sample included 293 school-aged children and adolescents with chronic health conditions and 197 parents. Both family members (whenever possible) completed the self- and proxy-report versions of Disabkids-10. The factorial model of Disabkids-10 had good fit for self-reported data and minimally acceptable fit for proxy-reported data. The multigroup analyses confirmed the model invariance across age-groups (children vs. adolescents), genders (boys vs. girls), and informants (children vs. parents). The generic developmental applicability of these questionnaires makes them recommended for health care routine assessments on pediatric intervention needs and outcomes. © The Author(s) 2014.

Current models of adolescent drinking behavior hypothesize that alcohol expectancies mediate the effects of other proximal and distal risk factors. This longitudinal study tested the hypothesis that the effects of parental alcohol involvement on their children’s drinking behavior in mid-adolescence are mediated by the children’s alcohol expectancies in early adolescence. A sample of 148 initially 9–11 year old boys and their parents from a high-risk population and a contrast group of community families completed measures of drinking behavior and alcohol expectancies over a 6-year interval. We analyzed data from middle childhood (M age = 10.4 years), early adolescence (M age = 13.5 years), and mid-adolescence (M age = 16.5 years). The sample was restricted only to adolescents who had begun to drink by mid-adolescence. Results from zero-inflated Poisson regression analyses showed that 1) maternal drinking during their children’s middle childhood predicted number of drinking days in middle adolescence; 2) negative and positive alcohol expectancies in early adolescence predicted odds of any intoxication in middle adolescence; and 3) paternal alcoholism during their children’s middle childhood and adolescents’ alcohol expectancies in early adolescence predicted frequency of intoxication in middle adolescence. Contrary to predictions, child alcohol expectancies did not mediate the effects of parental alcohol involvement in this high-risk sample. Different aspects of parental alcohol involvement, along with early adolescent alcohol expectancies, independently predicted adolescent drinking behavior in middle adolescence. Alternative pathways for the influence of maternal and paternal alcohol involvement and implications for expectancy models of adolescent drinking behavior were discussed. PMID:20853923

The present study aimed to assess the effects of an early childhood nutrition counselling intervention on intelligence (as measured by the intelligence quotient (IQ)) at age 15-16 years. A single-blind, cluster-randomised trial. In 1998, in Southern Brazil, mothers of children aged 18 months or younger were enrolled in a nutrition counselling intervention (n 424). Counselling included encouragement and promotion of exclusive breast-feeding until 6 months of age and continued breast-feeding supplemented by protein-, lipid- and carbohydrate-rich foods after age 6 months up to age 2 years. The control group received routine feeding advice. In 2013, the fourth round of follow-up of these individuals, at the age of 15-16 years, was undertaken. IQ was assessed using the short form of the Wechsler Adult Intelligence Scale (WAIS-III). Mental disorders (evaluated using the Development and Well-Being Assessment (DAWBA)) and self-reported school failure, smoking and alcohol use were also investigated. Adjusted analyses were conducted using a multilevel model in accordance with the sampling process. Adolescents, mean (sd) age of 15·4 (0·5) years (n 339). Mean (sd) total IQ score was lower in the intervention group than the control group (93·4 (11·4) and 95·8 (11·2), respectively) but the association did not persist after adjustment. The prevalence of any mental disorders was similar between intervention and control groups (23·1 and 23·5 %, respectively). There were no differences between groups regarding school failure, smoking and alcohol use. Nutrition counselling intervention in early childhood had no effect on intelligence measured during adolescence.

The aim of this study was to evaluate the relationship between psychological symptoms and quality of life (QOL) and clinical variables in a cohort of children and adolescents with non-cystic fibrosis (non-CF) bronchiectasis. Seventy-six patients (aged 8-17years) participated in this study. Questionnaires were used to evaluate the psychological status and QOL of the patients and healthy controls. The patient and control groups were divided into child and adolescent groups to exclude the effect of puberty on psychological status. No significant difference was found between patient and control groups for mean depression and trait anxiety scores. Only the child-rated physical health QOL scores were significantly lower for patients than the controls. Also, excepting physical health scores in adolescent group, all of the parent-rated QOL scores were significantly lower in both group and total subjects. Regarding determinants of QOL, age of children and FEV1/FVC percent predicted had positive effects, while dyspnea severity and trait anxiety had negative effects, for the sample as a whole. Non-CF bronchiectasis is associated with poorer QOL in childhood. The impact of the disease on QOL occurs through both clinical and psychological variables. Copyright © 2014 Elsevier Inc.

Drawing on two nationally representative German studies (N(1) = 1744, N(2) = 759), we examined correlates of early, on-time, and late curfew autonomy, a retrospective indicator of behavioural autonomy, in young and middle adulthood (19-37 years of age). Adjustment in four domains was considered: educational attainment, externalizing problem behaviour, subjective well-being, and interpersonal relationships. The early group showed lower adjustment in multiple domains across young and middle adulthood. The late group reported a mixed pattern of adjustment at younger ages (lower externalizing problems, but lower positive affect, lower importance of peers, and lower likelihood to have a partner) and positive adjustment in all domains at older ages. Timing effects were controlled for sociodemographic characteristics and retrospective measures of early adversities, pubertal timing, disclosure to parents, and peer group affiliation in adolescence. Findings show that late behavioural autonomy in its correlates is not simply the opposite of early behavioural autonomy.

Prospective longitudinal research is needed to examine associations between bullying behaviors and trajectories of suicidal ideation and behavior and overall functional impairment. The specific aims of the present study are to: (1) characterize differences in baseline functioning between acutely suicidal adolescents who are classified into bullying perpetrator and non-bully groups and (2) examine the 1-year trajectories of these two groups of adolescents. Participants were 433 psychiatrically hospitalized suicidal adolescents (72% female), ages 13 to 17 years. Participants reported suicidal ideation, depression, anxiety, substance use, adaptive functioning, and bullying behavior. Six items from the Youth Self-Report were used to classify adolescents into bullying perpetrator (n = 54) and non-bully (n = 379) groups. Follow-up assessments were conducted at 6 weeks, 3 months, 6 months, and 12 months. At hospitalization, adolescents in the bully group reported significantly higher levels of suicidal ideation, substance use, and functional impairment. Suicidal ideation differences remitted at six weeks. The elevated functional impairment of the bullying perpetrator group persisted across the 12-month period. Adolescents who met bullying perpetrator group criteria were characterized by more severe suicidal ideation and higher levels of proximal risk factors for suicide. Bullying behavior was not stable over time but was associated with elevated suicide risk when present. These findings highlight the importance of specifically assessing for and targeting bullying behavior at multiple time points when treating suicidal adolescents.

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.
