    2014-01-01

    Background Child and adolescent mental health problems are ubiquitous and burdensome. Their impact on functional disability, the high rates of accompanying medical illnesses and the potential to last until adulthood make them a major public health issue. While methodological factors cause variability of the results from epidemiological studies, there is a lack of prevalence rates of mental health problems in children and adolescents according to ICD-10 criteria from nationally representative samples. International findings suggest only a small proportion of children with function impairing mental health problems receive treatment, but information about the health care situation of children and adolescents is scarce. The aim of this epidemiological study was a) to classify symptoms of common mental health problems according to ICD-10 criteria in order to compare the statistical and clinical case definition strategies using a single set of data and b) to report ICD-10 codes from health insurance claims data. Methods a) Based on a clinical expert rating, questionnaire items were mapped on ICD-10 criteria; data from the Mental Health Module (BELLA study) were analyzed for relevant ICD-10 and cut-off criteria; b) Claims data were analyzed for relevant ICD-10 codes. Results According to parent report 7.5% (n = 208) met the ICD-10 criteria of a mild depressive episode and 11% (n = 305) showed symptoms of depression according to cut-off score; Anxiety is reported in 5.6% (n = 156) and 11.6% (n = 323), conduct disorder in 15.2% (n = 373) and 14.6% (n = 357). Self-reported symptoms in 11 to 17 year olds resulted in 15% (n = 279) reporting signs of a mild depression according to ICD-10 criteria (vs. 16.7% (n = 307) based on cut-off) and 10.9% (n = 201) reported symptoms of anxiety (vs. 15.4% (n = 283)). Results from routine data identify 0.9% (n = 1,196) with a depression diagnosis, 3.1% (n = 6,729) with anxiety and 1.4% (n

  2. In favour of the definition "adolescents with idiopathic scoliosis": juvenile and adolescent idiopathic scoliosis braced after ten years of age, do not show different end results. SOSORT award winner 2014

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

    Qualitative research was conducted in Brazil among 28 ayahuasca-consuming adolescents members of the União do Vegetal Church, and 28 adolescents who never used ayahuasca. They were compared on a number of qualitative variables, including vignettes measuring moral and ethical concerns. Psychocultural studies utilizing co-occurences of variables in the realm of qualitative studies are useful in understanding and complementing quantitative studies also conducted among this population. Qualitative data show that the teens in the União do Vegetal religion appear to be healthy, thoughtful, considerate and bonded to their families and religious peers. This study examines the modern use of a powerful hallucinogenic compound within a legal religious context, and the youth who participated in these ayahuasca religious ceremonies (usually with parents and other family members) appeared not to differ from their nonayahuasca-using peers. This study helps to elucidate the full range of effects of plant hallucinogenic use within a socially-sanctioned, elder-facilitated and structured religious context.

    Purpose. To evaluate glucose and insulin profiles in adolescents with mild stunting and overweight in order to assess the possibility of increased predisposition to diabetes. Subjects and Methods. The study population consisted of 66 pubertal adolescents classified as mildly stunted (height-for-age z scores ≥−2 and <−1) or of normal stature, as well as overweight (body mass index ≥85th percentile) or normal weight. Beta-cell function and insulin resistance were evaluated according to the homeostasis model assessment (HOMA). Results. In the group with mild stunting, glucose, insulin, and HOMA-IR levels were significantly higher in overweight adolescents compared with those of normal weight, whereas HOMA-B levels were significantly lower. Adolescents with mild stunting showed significantly higher accumulations of body and abdominal fat than their normal stature counterparts. Conclusions. The presence of mild stunting was associated with higher levels of glucose and insulin, diminished function of beta cells, and increased insulin resistance. These results reinforce the need for intervention in adolescents with mild stunting. PMID:21318152

    Aim Preterm birth is associated with a number of physical and mental health issues. The aim of this study was to find out if there was also any association between individuals born preterm in Sweden between 1984 and 2006 and the risk of unintentional injuries during childhood, adolescence and young adulthood. Methods The study followed 2,297,134 individuals, including 5.9% born preterm, from 1985 to 2007 for unintentional injuries leading to hospitalisation or death (n=244,021). The males and females were divided into four age groups: 1–5 years, 6–12 years, 13–18 years and 19–23 years. Hazard ratios were calculated for falls, transport injuries and other injuries. Results After adjusting for a comprehensive set of covariates, some of the preterm subgroups demonstrated slightly increased risks of unintentional injuries, while others showed slightly decreased risks. However, most of the estimates were borderline or non-significant in both males and females. In addition, the absolute risk differences between individuals born preterm and full term were small. Conclusion Despite the association between preterm birth and a variety of physical and mental health consequences, this study shows that there is no consistent risk pattern between preterm birth and unintentional injuries in childhood, adolescence and young adulthood.

    The great Sichuan earthquake in China on May 12, 2008 was a traumatic event to many who live near the earthquake area. However, at present, there are few studies that explore the long-term impact of the adolescent trauma exposure on adults' brain function. In the present study, we used functional magnetic resonance imaging (fMRI) to investigate the brain activation evoked by masked trauma-related stimuli (earthquake versus neutral images) in 14 adults who lived near the epicenter of the great Sichuan earthquake when they were adolescents (trauma-exposed group) and 14 adults who lived farther from the epicenter of the earthquake when they were adolescents (control group). Compared with the control group, the trauma-exposed group showed significant elevation of activation in the right anterior cingulate cortex (ACC) and the medial prefrontal cortex (MPFC) in response to masked earthquake-related images. In the trauma-exposed group, the right ACC activation was negatively correlated with the frequency of symptoms of post-traumatic stress disorder (PTSD). These findings differ markedly from the long-term effects of trauma exposure in adults. This suggests that trauma exposure during adolescence may have a unique long-term impact on ACC/MPFC function, top-down modulation of trauma-related information, and subsequent symptoms of PTSD.

    Background and Aims Adolescents with substance use disorders (SUD) exhibit hyposensitivity to pleasant internally generated (interoceptive) stimuli and hypersensitivity to external rewarding stimuli. It is unclear whether similar patterns exist for aversive interoceptive stimuli. We compared activation in the insular cortex and other brain regions during the anticipation and experience of aversive stimuli between adolescents with SUD and those without. Design and participants Cross-sectional experimental study with two groups: Adolescents (ages 15–17) with an alcohol or marijuana SUD (n=18) and healthy comparison subjects (CON, n=15). Participants were recruited by distributing flyers at local high schools. Setting Keck Imaging Center, University of California San Diego, USA. Measurements Behavioral and neural responses to a continuous performance task with inspiratory breathing load recorded during an fMRI session. Questionnaires assessed lifetime drug use, anxiety, sensation seeking, impulsivity, affect, and bodily awareness. Visual analogue scales assessed drug craving and breathing load responses. Findings Across subjects, experience of breathing load elicited greater bilateral anterior and posterior insula (AI and PI, respectively) activation than anticipation (F(1,31)=4.16, p<.05). SUD exhibited greater left AI and bilateral PI activation during breathing load than anticipation, compared with CON (F(1,31)=4.16, p<.05). In contrast, CON showed greater activation during anticipation than breathing load in left PI, compared with SUD (F(1,31)=4.16, p<.05). Conclusions Adolescents with alcohol and marijuana substance use disorders may be hypersensitive to aversive interoceptive stimuli. PMID:26234745

    Marijuana is the most widely used illicit substance among teenagers, yet little is known about the possible neural influence of heavy marijuana use during adolescence. We previously demonstrated an altered functional magnetic resonance imaging (fMRI) activity related to spatial working memory (SWM) among adolescents who were heavy users of after an average of 8 days of abstinence, but the persisting neural effects remain unclear. To characterize the potentially persisting neurocognitive effects of heavy marijuana use in adolescence, we examined fMRI response during SWM among abstinent marijuana-using teens. Participants were 15 MJ teens and 17 demographically similar non-using controls, ages 16–18. Teens underwent biweekly urine toxicology screens to ensure abstinence for 28 days before fMRI acquisition. Groups performed similarly on the SWM task, but MJ teens demonstrated lower activity in right dorsolateral prefrontal and occipital cortices, yet significantly more activation in right posterior parietal cortex. MJ teens showed abnormalities in brain response during a SWM task compared with controls, even after 1 month of abstinence. The activation pattern among MJ teens may reflect different patterns of utilization of spatial rehearsal and attention strategies, and could indicate altered neurodevelopment or persisting abnormalities associated with heavy marijuana use in adolescence.

    Introduction. Several studies have pointed to the high prevalence of low levels of physical activity in adolescents, suggesting the need for more effective interventions for this group. The aim of this study was to present evidence of intervention programs for efficacy of physical activity for adolescents. Methods. Surveys in PubMed, SportDiscus, LiLacs, and SciELO databases were conducted using keywords to identify population, intervention, and outcome, as well as DeCS and MeSH terms in English, Portuguese, and Spanish, whenever appropriate. The review included observational studies with minimal intervention of six months, minimum sample size of 100 adolescents, written in any language, and those who have reached STROBE score greater than 70%. Results. Only seven studies met all inclusion criteria. Of these, five were pre- and postintervention and two had n > 2000 participants. Interventions were of several types, durations, and strategies for physical activity implementation. Behavior change was assessed in 43% of studies and three reported success in some way. Conclusion. Due to heterogeneity in their contents and methodologies, as well as the lack of jobs that accompany adolescents after the intervention period, one cannot draw conclusions about the actual effects of the intervention programs of physical activity on the behavior of young people.

    Context MySpace is a popular social networking Web site where users create individual Web profiles. Little data are available about what types of health risk behaviors adolescents display on MySpace profiles. There are potential risks and intervention opportunities associated with posting such information on a public Web site. Objective To examine publicly available 16- and 17-year-old MySpace Web profiles and determine the prevalence of personal risk behavior descriptions and identifiable information. Design Cross-sectional observational study using content analysis of Web profiles. Setting www.MySpace.com Patients In order to target frequently visited adolescent Web profiles, we sequentially selected 142 publicly available Web profiles of 16 and 17 year olds from the class of 2008 MySpace group. Interventions None. Main outcome measures Prevalence of displayed health risk behaviors pertaining to substance use or sexual behavior, prevalence of personally identifying information, date of last log-in to Web profile. Results Of Web profiles, 47% contained risk behavior information: Twenty-one percent described sexual activity; 25% described alcohol use; 9% described cigarette use; and 6% described drug use. 97.2% Contained personally identifying information: Seventy-four percent included an identifiable picture; 75% included subjects' first names or surnames; and 78% included subjects' hometowns. Eighty-six percent of users had visited their own profiles within 24 hours. Conclusions Most 16- and 17-year-old MySpace profiles include identifiable information, are frequently accessed by owners, and half include personal risk behavior information. Further study is needed to assess the risks associated with displaying personal information and to evaluate the use of social networking sites for health behavior interventions targeting at-risk teens.

    Objectives To examine the efficacy of three theoretically distinct interventions among substance-abusing runaway adolescents and to explore individual differences in trajectories of change. Methods Adolescents (N=179) between the ages of 12–17 were recruited from a runaway shelter in a Midwestern city. The sample included 94 females (52.5%) and 85 males (47.5%), the majority of the adolescents were African American (n= 118, 65.9%). Adolescents were randomly assigned to the Community Reinforcement Approach (CRA, n = 57), Motivational Interviewing (MI, n = 61), or Ecologically-Based Family Therapy (EBFT, n = 61). Substance use was assessed at baseline, 3, 6, 9, 12, 18, and 24 months via Form 90 and urine screens. Results Hierarchical linear modeling revealed statistically significant improvement in frequency of substance use among runaways in all three treatment groups with a slight increase at post-treatment. Latent trajectory profile analysis explored individual differences in change trajectories and yielded a 3 class model. The majority of adolescents (n = 136, 76%) showed reductions in substance use over time with a slight increase at follow-up (Class 1: Decreasing). Twenty-four (13.4%) adolescents had shown high levels of substance use over time with patterns of increase and decrease (Class 2: Fluctuating high users), and 19 (10.6%) decreased but returned to baseline levels by two years post-baseline (Class 3: U shaped). Few differences among treatment conditions were noted; within the “decreasing” group, adolescents in MI treatment showed a quicker decline in their substance use but a faster relapse compared to those receiving EBFT. Conclusions These findings suggest that CRA, EBFT and MI are viable treatments for runaway substance-abusing adolescents. PMID:23895088

    Binge drinking, defined as achieving blood ethanol concentrations (BEC) of 80 mg%, has been increasing in adolescents and was reported to predispose later physical dependence. The present experiments utilized an animal model of binge drinking to compare the effect of ethanol "binge" experience during adolescence or adulthood on subsequent ethanol intake in male and female C57BL/6 mice. Adolescent and adult mice were initially exposed to the scheduled high alcohol consumption procedure, which produces BECs that exceed the levels for binge drinking following a 30-min ethanol session every third day. Ethanol intake and BECs were significantly higher in the adolescent ( approximately 3 g/kg, 199 mg%) versus adult ( approximately 2 g/kg, 135 mg%) mice during the first three ethanol sessions, but were more equivalent during the final two ethanol sessions (1.85-2.0 g/kg, 129-143 mg%). Then, separate groups of the ethanol-experienced mice were tested with ethanol naïve adolescent and adult mice for 2-h limited access (10% and 20% solutions) or 24-h (5%, 10% and 20% solutions) ethanol preference drinking. Limited access ethanol intake was significantly higher in female versus male mice, but was not altered by age or ethanol experience. In contrast, 24-h ethanol intake was significantly higher in the adolescent versus adult mice and in female versus male mice. Furthermore, binge drinking experience in the adolescent mice significantly increased subsequent ethanol intake, primarily due to intake in female mice. Thus, adolescent binge drinking significantly increased unlimited ethanol intake during adulthood, with female mice more susceptible to this effect.

    Do successful drug prevention programs suppress the risk factors they were intended to modify? This paper addresses that issue for Project ALERT, a school-based program for seventh and eighth graders that has been shown to curb both cigarette and marijuana use. Evaluated with over 4,000 students in an experimental test that included 30 diverse California and Oregon schools, the curriculum seeks to help young people develop both the motivation to avoid drugs and the skills they need to resist pro-drug pressures. Using regression analyses, we examine the program's impact on the intervening (cognitive) variables hypothesized to affect actual use: adolescent beliefs in their ability to resist, perceived consequences of use, normative perceptions about peer use and tolerance of drugs, and expectations of future use. The analysis depicts program effects for perceptions linked to each target substance (alcohol, cigarettes, and marijuana), across all students and for those at different levels of risk for future use. Results show that the curriculum successfully dampened cognitive risk factors from each of the above categories for both cigarettes and marijuana, indicating that social influence programs can mitigate a broad range of beliefs associated with the propensity to use drugs. However, it had a limited impact on beliefs about alcohol, the most widely used and socially accepted of the three drugs. Implications for drug prevention programs and practitioners are discussed.

    Caffeine is the most commonly ingested psychoactive drug worldwide with increasing consumption rates among young individuals. While caffeine leads to decreased sleep quality in adults, studies investigating how caffeine consumption affects children's and adolescents' sleep remain scarce. We explored the effects of regular caffeine consumption on sleep behavior and the sleep electroencephalogram (EEG) in children and adolescents (10-16 years). While later habitual bedtimes (Caffeine 23:14 ± 11.4, Controls 22:17 ± 15.4) and less time in bed were found in caffeine consumers compared to the control group (Caffeine 08:10 ± 13.3, Controls 09:03 ± 16.1), morning tiredness was unaffected. Furthermore, caffeine consumers exhibited reduced sleep EEG slow-wave activity (SWA, 1-4.5 Hz) at the beginning of the night compared to controls (20% ± 9% average reduction across all electrodes and subjects). Comparable reductions were found for alpha activity (8.25-9.75 Hz). These effects, however, disappeared in the morning hours. Our findings suggest that caffeine consumption in adolescents may lead to later bedtimes and reduced SWA, a well-established marker of sleep depth. Because deep sleep is involved in recovery processes during sleep, further research is needed to understand whether a caffeine-induced loss of sleep depth interacts with neuronal network refinement processes that occur during the sensitive period of adolescent development.

    Reduced fat dairy products are generally recommended for adults and children over the age of two years. However, emerging evidence suggests that dairy fat may not have detrimental health effects. We aimed to investigate prospective associations between consumption of regular versus reduced fat dairy products and cardiometabolic risk factors from early to late adolescence. In the West Australian Raine Study, dairy intake was assessed using semi-quantitative food frequency questionnaires in 860 adolescents at 14 and 17-year follow-ups; 582 of these also had blood biochemistry at both points. Using generalized estimating equations, we examined associations with cardiometabolic risk factors. Models incorporated reduced fat and regular fat dairy together (in serves/day) and were adjusted for a range of factors including overall dietary pattern. In boys, there was a mean reduction in diastolic blood pressure of 0.66 mmHg (95% CI 0.23–1.09) per serve of reduced fat dairy and an independent, additional reduction of 0.47 mmHg (95% CI 0.04–0.90) per serve of regular fat dairy. Each additional serve of reduced fat dairy was associated with a 2% reduction in HDL-cholesterol (95% CI 0.97–0.995) and a 2% increase in total: HDL-cholesterol ratio (95% CI 1.002–1.03); these associations were not observed with regular fat products. In girls, there were no significant independent associations observed in fully adjusted models. Although regular fat dairy was associated with a slightly better cholesterol profile in boys, overall, intakes of both regular fat and reduced fat dairy products were associated with similar cardiometabolic associations in adolescents.

    The adolescent transition from juvenile to adult is marked by anatomical and functional remodeling of brain networks. Currently, the cellular and synaptic level changes underlying the adolescent transition are only coarsely understood. Here, we use two-photon imaging to make time-lapse observations of long-range axons that innervate the frontal cortex in the living brain. We labeled cells in the orbitofrontal cortex (OFC) and basolateral amygdala (BLA) and imaged their axonal afferents to the dorsomedial prefrontal cortex (dmPFC). We also imaged the apical dendrites of dmPFC pyramidal neurons. Images were taken daily in separate cohorts of juvenile (P24-P28) and young adult mice (P64-P68), ages where we have previously discovered differences in dmPFC dependent decision-making. Dendritic spines were pruned across this peri-adolescent period, while BLA and OFC afferents followed alternate developmental trajectories. OFC boutons showed no decrease in density, but did show a decrease in daily bouton gain and loss with age. BLA axons showed an increase in both bouton density and daily bouton gain at the later age, suggesting a delayed window of enhanced plasticity. Our findings reveal projection specific maturation of synaptic structures within a single frontal region and suggest that stabilization is a more general characteristic of maturation than pruning.

    Early exposure to a traumatic event may produce lasting effects throughout the lifespan. Traumatic stress during adolescence may deliver a distinct developmental insult compared with more-often studied neonatal or juvenile traumatic stress paradigms. The present study describes the lasting effects of adolescent traumatic stress upon adulthood fear conditioning. Adolescent rats were exposed to a traumatic stressor (underwater trauma, UWT), then underwent fear conditioning during adulthood. Fear extinction was tested over five conditioned suppression extinction sessions three weeks later. The efficacies of two potential extinction-enhancing compounds, endocannabinoid reuptake inhibitor AM404 (10mg/kg) and M1 muscarinic positive allosteric modulator BQCA (10mg/kg), were also assessed. Finally, post-extinction fear responses were examined using a fear cue (light) as a prepulse stimulus. Rats traumatically stressed during adolescence showed blunted conditioned suppression on day 1 of extinction training, and AM404 reversed this effect. Post-extinction startle testing showed that fear conditioning eliminates prepulse inhibition to the light cue. Startle potentiation was observed only in rats without adolescent UWT exposure. AM404 and BQCA both ameliorated this startle potentiation, while BQCA increased startle in the UWT group. These results suggest that exposure to a traumatic stressor during adolescence alters developmental outcomes related to stress response and fear extinction compared to rats without adolescent traumatic stress exposure, blunting the adulthood fear response and reducing residual post-extinction fear expression. Efficacy of pharmacological interventions may also vary as a factor of developmental traumatic stress exposure.

    Ghrelin and peptide YY (PYY) stimulate hunger and satiety, respectively. The physiology of these hormones during normal meal intake remains unclear. This study was designed to compare the responses of these two hormones to meal intake between lean and obese Hispanic adolescents. A total of 10 obese and 7 lean Hispanic youth, aged 11-14 years, consumed two mixed meals, one small and one large, during which plasma measurements of active and total ghrelin and total PYY were obtained. Obese subjects tended to consume more calories during the small meal than lean subjects, although this did not reach statistical significance. Intake of the small meal significantly suppressed active ghrelin and stimulated PYY levels in the lean subjects, and these changes were further accentuated by the large meals. In obese subjects, the suppression of active ghrelin and stimulation of PYY by caloric intake were blunted. Interestingly, a paradoxical stimulation of active ghrelin levels was noted during the small meals in both lean and obese subjects. This stimulation was not seen during the larger meals in lean subjects, but remained present in the obese subjects. Thus, meal-related changes in active ghrelin and PYY are blunted in obese as compared to lean Hispanic subjects. This blunting could contribute to the development or worsening of obesity.

    The topographic distribution of slow wave activity (SWA, EEG power between 0.75 and 4.5 Hz) during non-rapid eye movement (NREM) sleep was proposed to mirror cortical maturation with a typical age-related pattern. Here, we examined whether sex differences occur in SWA topography of children and adolescents (22 age-matched subjects, 11 boys, mean age 13.4 years, range: 8.7-19.4, and 11 girls, mean age 13.4 years, range: 9.1-19.0 years). In females, SWA during the first 60 min of NREM sleep was higher over bilateral cortical areas that are related to language functions, while in males SWA was increased over the right prefrontal cortex, a region also involved in spatial abilities. We conclude that cortical areas governing functions in which one sex outperforms the other exhibit increased sleep SWA and, thus, may indicate maturation of sex-specific brain function and higher cortical plasticity during development.

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

    Objective This study was aimed to evaluate the recent trends in contraceptive use among Korean adolescents. Methods Data reviewed were from the 2013–2015 Korean Youth Risk Behavior Web-based Survey, which is a stratified, multistage-sampling designed online-based research project performed annually by the Korean government to ensure a nationally representative sample of Korean adolescence. Eight questions related to the topic of contraception were reviewed for the outcome variables. Results A total of 212,538 adolescents attending middle school and high school participated in the survey, and 8,755 students among them who were sexually active were included in the study. The percentage of contraceptive use showed a steady increase from 39% in 2013 to 48.7% in 2015; however, the proportion of adolescents who have never used any kind of contraception still remains high. Highly effective methods such as oral contraceptives and intrauterine devices were used by only 10% to 15% of sexually active adolescents. Conclusion The present study demonstrates the status of contraceptive use among Korean adolescents. Our data have the potential to help healthcare providers to formulate policies and develop interventions for encouraging effective contraceptive use among sexually active Korean adolescents.

    Exposure to maternal separation (MS) during early life is an identified risk factor for emotional disorders such as anxiety and depression later in life. This study investigated the effects of neonatal MS on the behavior and long-term potentiation (LTP) as well as basic synaptic transmission at hippocampal CA3-CA1 and mossy fiber (MF)-CA3 synapses in adolescent mice for 19days. When mice were adolescents, we measured depression, learning, memory, anxious and aggressive behavior using the forced swimming test (FST), Y-maze, Morris water maze (MWM), elevated plus maze (EPM), three consecutive days of the open field test, the social interaction test, the tube-dominance test and the resident-intruder test. The results showed that there was no difference in FST, Y-maze, and MWM performance. However, MS mice showed more anxiety-like behavior in the EPM test and aggressive-like behavior in the tube-dominance and resident-intruder tests. In addition, the magnitude of LTP and release probability in the MF-CA3 synapses was reduced in the MS group but not in the CA3-CA1 synapse. Our results indicate that early life stress due to MS may induce anxiety- and aggressive-like behavior during adolescence, and these effects are associated with synaptic plasticity at the hippocampal MF-CA3 synapses.

    Research suggests that adolescents' engagement in nonsuicidal self-injurious (NSSI) behaviors may be increasing over time, yet little is known regarding distal longitudinal factors that may promote engagement in these behaviors. Data from two longitudinal studies are presented to examine whether NSSI may be associated with peer influence processes. Study 1 included 377 adolescents from a community-based sample; Study 2 included 140 clinically-referred adolescents recruited from a psychiatric inpatient facility. In Study 1, adolescents' NSSI was examined at baseline and one year later. Adolescents' nominated best friend reported their own levels of NSSI. In Study 2, adolescents' NSSI was examined at baseline as well as 9 and 18-months post-baseline. Adolescents' perceptions of their friends' engagement in self-injurious behavior (including suicidality) and depressed mood also were examined at all three time points. Baseline depressive symptoms were measured in both studies; gender and age were examined as moderators of peer influence effects. Results from both studies supported longitudinal peer socialization effects of friends' self-injurious behavior on adolescents' own NSSI for girls, but not for boys, even after controlling for depressive symptoms as a predictor. Study 1 suggested socialization effects mostly for younger youth. Results from Study 2 also suggested longitudinal socialization effects, as well as peer selection effects; adolescents' NSSI was associated with increasing perceptions of their friends' engagement in depressive/self-injurious thoughts and behavior. Findings contribute to the nascent literature on longitudinal predictors of NSSI and to work on peer influence. PMID:20437255

    2010-10-01

    A widely publicized but unpublished study of the relationship between gun shows and gun violence is being cited in debates about the regulation of gun shows and gun commerce. We believe the study is fatally flawed. A working paper entitled "The Effect of Gun Shows on Gun-Related Deaths: Evidence from California and Texas" outlined this study, which found no association between gun shows and gun-related deaths. We believe the study reflects a limited understanding of gun shows and gun markets and is not statistically powered to detect even an implausibly large effect of gun shows on gun violence. In addition, the research contains serious ascertainment and classification errors, produces results that are sensitive to minor specification changes in key variables and in some cases have no face validity, and is contradicted by 1 of its own authors' prior research. The study should not be used as evidence in formulating gun policy.

    Marijuana is one of the most commonly used drugs in the United States, and use during adolescence--when the brain is still developing--has been proposed as a cause of poorer neurocognitive outcome. Nonetheless, research on this topic is scarce and often shows conflicting results, with some studies showing detrimental effects of marijuana use on cognitive functioning and others showing no significant long-term effects. The purpose of the present study was to examine the associations of marijuana use with changes in intellectual performance in two longitudinal studies of adolescent twins (n = 789 and n = 2,277). We used a quasiexperimental approach to adjust for participants' family background characteristics and genetic propensities, helping us to assess the causal nature of any potential associations. Standardized measures of intelligence were administered at ages 9-12 y, before marijuana involvement, and again at ages 17-20 y. Marijuana use was self-reported at the time of each cognitive assessment as well as during the intervening period. Marijuana users had lower test scores relative to nonusers and showed a significant decline in crystallized intelligence between preadolescence and late adolescence. However, there was no evidence of a dose-response relationship between frequency of use and intelligence quotient (IQ) change. Furthermore, marijuana-using twins failed to show significantly greater IQ decline relative to their abstinent siblings. Evidence from these two samples suggests that observed declines in measured IQ may not be a direct result of marijuana exposure but rather attributable to familial factors that underlie both marijuana initiation and low intellectual attainment.

  18. Astronomy Diagnostic Test Results Reflect Course Goals and Show Room for Improvement

    NASA Astrophysics Data System (ADS)

    Lopresto, Michael C.

    The results of administering the Astronomy Diagnostic Test (ADT) to introductory astronomy students at Henry Ford Community College over three years have shown gains comparable with national averages. Results have also accurately corresponded to course goals, showing greater gains in topics covered in more detail, and lower gains in topics covered in less detail. Also evident in the results were topics for which improvement of instruction is needed. These factors and the ease with which the ADT can be administered constitute evidence of the usefulness of the ADT as an assessment instrument for introductory astronomy.

    The purpose of this report is to examine relations between extreme thinking, as measured by the Dysfunctional Attitudes Scale, and the maintenance of gains among adolescents who participated in the Treatment for Adolescents with Depression Study (TADS). We examine extreme thinking among 327 adolescents (mean age = 14.56, 57% female, 75% White) who received cognitive behavior therapy (CBT), fluoxetine (FLX), or a combination of CBT and FLX (COMB). Among those who met remission status on the Children's Depression Rating Scale – Revised (CDRS-R ≤ 28; 56 at week 12, 79 at week 18) extreme thinking did not predict failure to maintain remission. This is in contrast to findings with depressed adults. Treatment influenced level of extreme thinking, and this appeared to be driven by greater endorsement of positively valenced beliefs as opposed to a decrease in negatively valenced beliefs. Developmental or investigation characteristics may account for the discrepancy in findings. PMID:20843506

    ABSTRACT Background Assessments of motor-functional aspects in cerebral palsy are crucial to rehabilitation programs. Objective To introduce the Sarah motor-functional evaluation scale and to report the initial results of its measurement properties. This scale was created based on the experience of the Sarah Network of Rehabilitation Hospitals in the care of children and adolescents with cerebral palsy. Method Preliminary results concerning the measurement properties of the scale were obtained via assessment of 76 children and adolescents with cerebral palsy. Experts' opinions were used to determine an expected empirical score by age group and to differentiate severity levels. Results The scale exhibited a high Cronbach’s alpha coefficient (0.95). Strong correlation was observed with experts’ classification for severity levels (0.81 to 0.97) and with the scales Gross Motor Function Measure and Pediatric Evaluation of Disability Inventory (0.80 to 0.98). Regression analysis detected a significant relationship between the scale score and the severity of the child’s motor impairment. The inter-rater reliability was also strong (intraclass correlation coefficient ranging from 0.98 to 0.99). The internal responsiveness of the scale score was confirmed by significant differences between longitudinal evaluations (paired Student’s t test with p<0.01; standardized response mean of 0.60). Conclusion The Sarah scale provides a valid measure for assessing the motor skills and functional performance of children and adolescents with cerebral palsy. The preliminary results showed that the Sarah scale has potential for use in routine clinical practice and rehabilitation units. PMID:27437718

    Purpose: Despite the growing evidence that ecological factors contribute to substance use, the relationship of ecological factors and illicit drugs such as marijuana use is not well understood, particularly among adolescents in Latin America. Guided by social disorganization and social stress theories, we prospectively examined the association of disaggregated neighborhood characteristics with marijuana use among adolescents in Santiago, Chile, and tested if these relationships varied by sex. Methods: Data for this study are from 725 community-dwelling adolescents participating in the Santiago Longitudinal Study, a study of substance using behaviors among urban adolescents in Santiago, Chile. Adolescents completed a two-hour interviewer administered questionnaire with questions about drug use and factors related to drug using behaviors. Results: As the neighborhood levels of drug availability at baseline increased, but not crime or noxious environment, adolescents had higher odds of occasions of marijuana use at follow up, approximately 2 years later (odds ratio [OR] = 1.39; 95% CI = 1.16–1.66), even after controlling for the study’s covariates. No interactions by sex were significant. Discussion: The findings suggest that “poverty”, “crime”, and “drug problems” may not be synonyms and thus can be understood discretely. As Latin American countries re-examine their drug policies, especially those concerning decriminalizing marijuana use, the findings suggest that attempts to reduce adolescent marijuana use in disadvantaged neighborhoods may do best if efforts are concentrated on specific features of the “substance abuse environment”.

    Abstract Objective: The purpose of this study was to conduct a pilot randomized trial of dialectical behavior therapy (DBT) versus psychosocial treatment as usual (TAU) for adolescents diagnosed with bipolar disorder (BP). Methods: We recruited participants 12–18 years of age with a primary BP diagnosis (I, II, or operationalized not otherwise specified [NOS] criteria) from a pediatric specialty clinic. Eligible patients were assigned using a 2:1 randomization structure to either DBT (n=14) or psychosocial TAU (n=6). All patients received medication management from a study-affiliated psychiatrist. DBT included 36 sessions (18 individual, 18 family skills training) over 1 year. TAU was an eclectic psychotherapy approach consisting of psychoeducational, supportive, and cognitive behavioral techniques. An independent evaluator, blind to treatment condition, assessed outcomes including affective symptoms, suicidal ideation and behavior, nonsuicidal self-injurious behavior, and emotional dysregulation, quarterly over 1 year. Results: Adolescents receiving DBT attended significantly more therapy sessions over 1 year than did adolescents receiving TAU, possibly reflecting greater engagement and retention; both treatments were rated as highly acceptable by adolescents and parents. As compared with adolescents receiving TAU, adolescents receiving DBT demonstrated significantly less severe depressive symptoms over follow-up, and were nearly three times more likely to demonstrate improvement in suicidal ideation. Models indicate a large effect size, for more weeks being euthymic, over follow-up among adolescents receiving DBT. Although there were no between-group differences in manic symptoms or emotional dysregulation with treatment, adolescents receiving DBT, but not those receiving TAU, evidenced improvement from pre- to posttreatment in both manic symptoms and emotional dysregulation. Conclusions: DBT may offer promise as an adjunct to pharmacotherapy in the treatment

    There is expedient evidence showing that differences in adolescent alcohol consumption and other risk-behaviour depend on both family structure and family member drunkenness exposure. Data were obtained among adolescents (N = 12,115, mean age 14.9 ± 0.89) in Austria, Estonia, France, Germany, Hungary, Ireland, Israel, Italy, Romania, Slovenia and Spain within the European Union’s 7th Framework Programme funded project, ‘Saving and Empowering Young Lives in Europe (SEYLE)’. The current study reveals how adolescents’ alcohol consumption patterns are related to their family structure and having seen their family member drunk. The results revealed statistically significant differences in adolescent alcohol consumption depending on whether the adolescent lives in a family with both birth parents, in a single-parent family or in a family with one birth parent and one step-parent. The study also revealed that the abstaining from alcohol percentage among adolescents was greater in families with both birth parents compared to other family types. The study also showed that the more often adolescents see their family member drunk the more they drink themselves. There is no difference in adolescent drinking patterns whether they see their family member drunk once a month or once a week. This study gives an insight on which subgroups of adolescents are at heightened risk of alcohol abuse and that decrease of family member drunkenness may have positive effects on the drinking habits of their children.

    Despite social media use being one of the most popular activities among adolescents, prevalence estimates among teenage samples of social media (problematic) use are lacking in the field. The present study surveyed a nationally representative Hungarian sample comprising 5,961 adolescents as part of the European School Survey Project on Alcohol and Other Drugs (ESPAD). Using the Bergen Social Media Addiction Scale (BSMAS) and based on latent profile analysis, 4.5% of the adolescents belonged to the at-risk group, and reported low self-esteem, high level of depression symptoms, and elevated social media use. Results also demonstrated that BSMAS has appropriate psychometric properties. It is concluded that adolescents at-risk of problematic social media use should be targeted by school-based prevention and intervention programs. PMID:28068404

    Objective Adolescent substance use is an area of concern because early substance use is associated with a higher risk of adverse outcomes. Parenting style, defined as the general style of parenting, as well as substance-specific parenting practices may influence children's substance use behaviour. The present study aims to probe the impact of parenting style on adolescent substance use. Method A cohort of 1268 adolescents (48% girls), aged 12–13 years at baseline, from 21 junior high schools was assessed in the first semester of junior high school, and then again in the last semester of the 9th grade, 32 months later. Parenting style, operationalised as a fourfold classification of parenting styles, including established risk factors for adolescent substance use, were measured at baseline. Results Neglectful parenting style was associated with worse substance use outcomes across all substances. After adjusting for other proximal risk factors in multivariate analyses, parenting style was found to be unrelated to substance use outcomes with one exception: authoritative parenting style was associated with less frequent drinking. Association with deviant peers, delinquent behaviour, provision of alcohol by parents, and previous use of other substances were associated with substance use outcomes at follow-up. Conclusions The results of the present study indicate that parenting style may be less important for adolescent substance use outcomes than what has previously been assumed, and that association with deviant peers and delinquent behaviour may be more important for adolescent substance use outcomes than general parenting style.

    Theorists posit that certain behaviors exhibited by depressed individuals (e.g., negative self-statements, dependency, reassurance seeking, inappropriate or premature disclosures, passivity, social withdrawal) reduce social support, yet there have been few experimental tests of this hypothesis. Using data from a randomized depression prevention trial (N=253) involving adolescents (M age=15.5, SD=1.2), we tested whether a cognitive behavioral group intervention that significantly reduced depressive symptoms relative to bibliotherapy and educational brochure control conditions through 2-year follow-up produced improvements in perceived parental and friend social support and whether change in depressive symptoms mediated the effect on change in social support. Cognitive behavioral group participants showed significantly greater increases in perceived friend social support through 1-year follow-up relative to bibliotherapy and brochure controls, but there were no significant effects for perceived parental support. Further, change in depressive symptoms appeared to mediate the effects of the intervention on change in perceived friend support. Results provide experimental support for the theory that depressive symptoms are inversely related to perceived social support, but imply that this effect may be specific to friend vs. parental support for adolescents.

    Indirect evidence (dust accumulation) has been obtained indicating that the Mars Pathfinder rover, Sojourner, experienced electrostatic charging on Mars. Lander camera images of the Sojourner rover provide distinctive evidence of dust accumulation on rover wheels during traverses, turns, and crabbing maneuvers. The sol 22 (22nd Martian "day" after Pathfinder landed) end-of-day image clearly shows fine red dust concentrated around the wheel edges with additional accumulation in the wheel hubs. A sol 41 image of the rover near the rock "Wedge" (see the next image) shows a more uniform coating of dust on the wheel drive surfaces with accumulation in the hubs similar to that in the previous image. In the sol 41 image, note particularly the loss of black-white contrast on the Wheel Abrasion Experiment strips (center wheel). This loss of contrast was also seen when dust accumulated on test wheels in the laboratory. We believe that this accumulation occurred because the Martian surface dust consists of clay-sized particles, similar to those detected by Viking, which have become electrically charged. By adhering to the wheels, the charged dust carries a net nonzero charge to the rover, raising its electrical potential relative to its surroundings. Similar charging behavior was routinely observed in an experimental facility at the NASA Lewis Research Center, where a Sojourner wheel was driven in a simulated Martian surface environment. There, as the wheel moved and accumulated dust (see the following image), electrical potentials in excess of 100 V (relative to the chamber ground) were detected by a capacitively coupled electrostatic probe located 4 mm from the wheel surface. The measured wheel capacitance was approximately 80 picofarads (pF), and the calculated charge, 8 x 10(exp -9) coulombs (C). Voltage differences of 100 V and greater are believed sufficient to produce Paschen electrical discharge in the Martian atmosphere. With an accumulated net charge of 8 x 10(exp

    Lymphoedema is a debilitating condition, manifesting in excess lymphatic fluid and swelling of subcutaneous tissues. Lymphoedema is as of yet still an incurable condition and current treatment modalities are not satisfactory. The capacity of mesenchymal stem cells to promote angiogenesis, secrete growth factors, regulate the inflammatory process, and differentiate into multiple cell types make them a potential ideal therapy for lymphoedema. Adipose tissue is the richest and most accessible source of mesenchymal stem cells and they can be harvested, isolated, and used for therapy in a single stage procedure as an autologous treatment. The aim of this paper was to review all studies using mesenchymal stem cells for lymphoedema treatment with a special focus on the potential use of adipose-derived stem cells. A systematic search was performed and five preclinical and two clinical studies were found. Different stem cell sources and lymphoedema models were used in the described studies. Most studies showed a decrease in lymphoedema and an increased lymphangiogenesis when treated with stem cells and this treatment modality has so far shown great potential. The present studies are, however, subject to bias and more preclinical studies and large-scale high quality clinical trials are needed to show if this emerging therapy can satisfy expectations.

    Heavy cannabis abuse increases the risk of developing schizophrenia. Adolescents appear particularly vulnerable to the development of psychosis-like symptoms after cannabis use. To test whether the schizophrenia candidate gene neuregulin 1 (NRG1) modulates the effects of cannabinoids in adolescence, we tested male adolescent heterozygous transmembrane domain Nrg1 mutant (Nrg1 TM HET) mice and wild type-like littermates (WT) for their neurobehavioural response to repeated Δ(9)-tetrahydrocannabinol (THC, 10 mg/kg i.p. for 21 d starting on post-natal day 31). During treatment and 48 h after treatment withdrawal, we assessed several behavioural parameters relevant to schizophrenia. After behavioural testing we measured autoradiographic CB(1), 5-HT(2A) and NMDA receptor binding. The hyperlocomotor phenotype typical of Nrg1 mutants emerged after drug withdrawal and was more pronounced in vehicle than THC-treated Nrg1 TM HET mice. All mice were equally sensitive to THC-induced suppression of locomotion. However, mutant mice appeared protected against inhibiting effects of repeated THC on investigative social behaviours. Neither THC nor Nrg1 genotype altered prepulse inhibition. Repeated adolescent THC promoted differential effects on CB(1) and 5-HT(2A) receptor binding in the substantia nigra and insular cortex respectively, decreasing binding in WT while increasing it in Nrg1 TM HET mice. THC also selectively affected 5-HT(2A) receptor binding in several other regions in WT mice, whereas NMDA receptor binding was only affected in mutant mice. Overall, Nrg1 mutation does not appear to increase the induction of psychotomimetic symptoms by repeated adolescent THC exposure but may attenuate some of its actions on social behaviour and schizophrenia-relevant neurotransmitter receptor profiles.

  13. AMS 14C analysis of teeth from archaeological sites showing anomalous esr dating results

    We have carried out AMS radiocarbon analysis on two groups of samples: the first one gave reasonable ESR age estimates and the second one yielded serious age underestinations. All samples were supposedly older than 35 ka, the oldest being around 160 ka. Two pretreatment techniques were used for radiocarbon dating: acid evolution and thermal release. Heating to 600, 750 and 900°C combined with total de-gassing at these temperatures was chosen to obtain age estimates on the organic fraction, secondary carbonates and original carbonate present in the hydroxyapatite mineral phase, respectively. All radiocarbon results present serious age underestimations. The secondary carbonate fraction gives almost modern results indicating an extremely rapid exchange of this component. Owing to this very rapid carbonate exchange it is not likely that the ESR signals used for dating are associated with the secondary carbonates. One tooth from Tabun with independent age estimates of >150 ka was further investigated by the Oxford AMS laboratory, yielding an age estimate of 1930±100 BP on the residual collagen from dentine and 18,000±160 BP on the carbonate component of the enamel bioapatite. We did not, however, find an explanation of why some samples give serious ESR underestimatioils whilst many others provide reasonable results.

    Regular physical activity has a positive effect on health and wellbeing at any age. For this reason, sports and exercise enhancing measures are inherent parts of public health in Germany. The German Health Interview and Examination Survey for Children and Adolescents (KiGGS) provides a nationally representative database which allows a comprehensive analysis of physical activity behaviour among young people. This may support the planning and implementation of health intervention measures. Primary results of KiGGS indicate that most children aged 3 to 10 years regularly go in for sports: around three quarters of girls and boys go in for sports at least once a week, and even more than one third three times a week or more. Children without sport engagement come disproportionately often from families with low socioeconomic status, with a migration background or from former East Germany. Also among adolescents sports and exercise activity is very common. Among 11-17 year olds, how ever, the current recommendation to conduct physical and or sports activities on most days of the week is only achieved by every fourth boy and every sixth girl. Especially girls with low socioeconomic status and with a migration background show a lack of physical activity. These results underline the importance of sports- and exercise-promoting measures in childhood and adolescence, designed for specific target groups.

    Delayed responses during cardiac arrest are common. Timely interventions during cardiac arrest have a direct impact on patient survival. Integration of technology in nursing education is crucial to enhance teaching effectiveness. The goal of this study was to investigate the effect of animation on nursing students' response time to cardiac arrest, including initiation of timely chest compression. Nursing students were randomized into experimental and control groups prior to practicing in a high-fidelity simulation laboratory. The experimental group was educated, by discussion and animation, about the importance of starting cardiopulmonary resuscitation upon recognizing an unresponsive patient. Afterward, a discussion session allowed students in the experimental group to gain more in-depth knowledge about the most recent changes in the cardiac resuscitation guidelines from the American Heart Association. A linear mixed model was run to investigate differences in time of response between the experimental and control groups while controlling for differences in those with additional degrees, prior code experience, and basic life support certification. The experimental group had a faster response time compared with the control group and initiated timely cardiopulmonary resuscitation upon recognition of deteriorating conditions (P < .0001). The results demonstrated the efficacy of combined teaching modalities for timely cardiopulmonary resuscitation. Providing opportunities for repetitious practice when a patient's condition is deteriorating is crucial for teaching safe practice.

    Cardiac emboli can have devastating consequences if they enter the cerebral circulation, and are the most common cause of embolic stroke. Little is known about relationships of embolic origin/density/size to cerebral events; as these relationships are difficult to observe. To better understand stoke risk from cardiac and aortic emboli, we developed a computational model to track emboli from the heart to the brain. Patient-specific models of the human aorta and arteries to the brain were derived from CT angiography from 10 MHIF patients. Blood flow was modeled by the Navier-Stokes equations using pulsatile inflow at the aortic valve, and physiologic Windkessel models at the outlets. Particulate was injected at the aortic valve and tracked using modified Maxey-Riley equations with a wall collision model. Results demonstrate aortic emboli that entered the cerebral circulation through the carotid or vertebral arteries were localized to specific locations of the proximal aorta. The percentage of released particles embolic to the brain markedly increased with particle size from 0 to ~1-1.5 mm in all patients. Larger particulate became less likely to traverse the cerebral vessels. These findings are consistent with sparse literature based on transesophageal echo measurements.

    Nursing facility residents are frequently admitted to the hospital, and these hospital stays are often potentially avoidable. Such hospitalizations are detrimental to patients and costly to Medicare and Medicaid. In 2012 the Centers for Medicare and Medicaid Services launched the Initiative to Reduce Avoidable Hospitalizations among Nursing Facility Residents, using evidence-based clinical and educational interventions among long-stay residents in 143 facilities in seven states. In state-specific analyses, we estimated net reductions in 2015 of 2.2-9.3 percentage points in the probability of an all-cause hospitalization and 1.4-7.2 percentage points in the probability of a potentially avoidable hospitalization for participating facility residents, relative to comparison-group members. In that year, average per resident Medicare expenditures were reduced by $60-$2,248 for all-cause hospitalizations and by $98-$577 for potentially avoidable hospitalizations. The effects for over half of the outcomes in these analyses were significant. Variability in implementation and engagement across the nursing facilities and organizations that customized and implemented the initiative helps explain the variability in the estimated effects. Initiative models that included registered nurses or nurse practitioners who provided consistent clinical care for residents demonstrated higher staff engagement and more positive outcomes, compared to models providing only education or intermittent clinical care. These results provide promising evidence of an effective approach for reducing avoidable hospitalizations among nursing facility residents.

    The number of studies on patch-test results in children and adolescents has gradually increased in recent years, thus stimulating reviews. This paper is a systematic review of a 15-year period devoted to studying the issue. Variations pertaining to the number and age groups of tested children and/or adolescents, the number of subjects with atopy/atopic dermatitis history, the quantity, type and concentrations of the tested substances, the test technique and type of data regarding clinical relevance, must all be considered in evaluating these studies, as they make it harder to formulate conclusions. The most common allergens in children were nickel, thimerosal, cobalt, fragrance, lanolin and neomycin. In adolescents, they were nickel, thimerosal, cobalt, fragrance, potassium dichromate, and Myroxylon pereirae. Knowledge of this matter aids health professionals in planning preventive programs aimed at improving children's quality of life and ensuring that their future prospects are not undermined.

    Objective We identify drinking styles that place teens at greatest risk of later alcohol use disorders (AUD). Design Population-based cohort study. Setting Victoria, Australia. Participants A representative sample of 1943 adolescents living in Victoria in 1992. Outcome measures Teen drinking was assessed at 6 monthly intervals (5 waves) between mean ages 14.9 and 17.4 years and summarised across waves as none, one, or two or more waves of: (1) frequent drinking (3+ days in the past week), (2) loss of control over drinking (difficulty stopping, amnesia), (3) binge drinking (5+ standard drinks in a day) and (4) heavy binge drinking (20+ and 11+ standard drinks in a day for males and females, respectively). Young Adult Alcohol Use Disorder (AUD) was assessed at 3 yearly intervals (3 waves) across the 20s (mean ages 20.7 through 29.1 years). Results We show that patterns of teen drinking characterised by loss of control increase risk for AUD across young adulthood: loss of control over drinking (one wave OR 1.4, 95% CI 1.1 to 1.8; two or more waves OR 1.9, CI 1.4 to 2.7); binge drinking (one wave OR 1.7, CI 1.3 to 2.3; two or more waves OR 2.0, CI 1.5 to 2.6), and heavy binge drinking (one wave OR 2.0, CI 1.4 to 2.8; two or more waves OR 2.3, CI 1.6 to 3.4). This is not so for frequent drinking, which was unrelated to later AUD. Although drinking was more common in males, there was no evidence of sex differences in risk relationships. Conclusions Our results extend previous work by showing that patterns of drinking that represent loss of control over alcohol consumption (however expressed) are important targets for intervention. In addition to current policies that may reduce overall consumption, emphasising prevention of more extreme teenage bouts of alcohol consumption appears warranted. PMID:26868948

    We examined developmental trends and sources of stability and change in adolescent personality by using twin data collected from 1981 to 2010 (273 monozygotic (MZ) and 48 dizygotic (DZ) twin pairs) from a secondary school affiliated with the University of Tokyo. Phenotypic analyses showed high rank-order stability and substantial mean-level increases in neuroticism and declines in extraversion over the adolescent years. Longitudinal bivariate genetic analyses revealed that the best-fitting model for adolescent personality includes additive genetic and non-shared environmental influences. Heritability estimates ranged approximately from 0.30 to 0.60. Additionally, three-year stability in adolescent personality was influenced mainly by genetic factors, and there were both genetic and environmental innovations in mid-adolescence. Our findings suggest that both genetic and environmental effects have significant roles in the etiology of personality development across adolescence.

    Emotion-regulation difficulties have been identified as one of the core components in Non-suicidal self-injury (NSSI), a behaviour often beginning in adolescence. This pilot study evaluated differences in emotion processing between 18 female adolescents with and without NSSI by using verbal responses and functional magnetic resonance imaging (fMRI). Responses to pictures taken from the International Affective Picture System and slides with reference to NSSI were recorded both by verbal rating of valence and arousal and by fMRI. The NSSI group rated pictures with self-injurious reference as significantly more arousing than controls. For emotional pictures, the NSSI group showed a significantly stronger brain response in the amygdala, hippocampus and anterior cingulate cortex bilaterally. Depression explained differences between groups in the limbic area. Furthermore, the NSSI group also showed increased activity in the middle orbitofrontal cortex, and inferior and middle frontal cortex when viewing NSSI picture material. Participants with NSSI showed decreased activity in correlation to arousal in the occipital cortex and to valence in inferior frontal cortex when watching emotional pictures. The fMRI data support the notion that individuals with NSSI show an altered neural pattern for emotional and NSSI pictures. Behavioural data highlight proneness to excitement regarding NSSI topics. This fMRI study provides evidence for emotion-regulation deficits in the developing brain of adolescents with NSSI.

    Objectives: A multisite study was undertaken to advance our understanding of how coping skills, depression, and suicidal ideation are related among adolescents who attempt suicide. Two hypotheses were postulated: productive coping and nonproductive coping would be associated, respectively, with lower and higher depression scores when age, sex, and stressful life events (SLEs) were controlled; and productive coping and nonproductive coping would be associated, respectively, with the presence and absence of suicidal ideation when age, sex, and SLEs were controlled. Methods: Participants were 167 adolescents (13 to 17 years of age) hospitalized for attempting suicide in 5 pediatric departments across France. Four instruments were administered: the Kiddie Schedule for Affective Disorders and Schizophrenia—Present and Lifetime Version, the Adolescent Coping Scale, the Life Events Questionnaire, and the Columbia-Suicide Severity Rating Scale. Descriptive analyses and univariate and multiple regression models were completed. Results: Both hypotheses were confirmed. Focus on the positive emerged as a significant variable in both models; depression emerged as a significant variable in the suicidal ideation model. The only sex difference observed was that girls made greater use of wishful thinking and seek social support. Conclusions: These findings suggest that coping skills are important mechanisms through which depression and suicidal ideation are maintained after attempting suicide. In intervening with adolescents who have attempted suicide, it may be useful to emphasize cognitive work geared to looking on the bright side, positive thinking, and fighting depression.

    Internationally adopted adolescents are at increased risk for mental health problems. However, little is known about problematic alcohol and drug use, which are important indicators of maladjustment. The aim of this study was to examine the level of problematic alcohol and drug use in internationally adopted adolescents compared to their nonadopted peers. The study is based on data from the youth@hordaland-survey, which was conducted in Hordaland County, Norway, in the spring of 2012. All adolescents born from 1993 to 1995 residing in Hordaland at the time of the study were invited to participate. Information on adoption was obtained from the Central Adoption Registry and linked to self-report data from the youth@hordaland-survey. Among 10,200 participants, 45 were identified as internationally adopted. No significant differences were found between international adoptees and their peers regarding whether or not they had tried alcohol or illicit drugs or their patterns of drinking behavior. However, adopted adolescents had a higher mean score on a measure of problematic alcohol and drug use compared to their nonadopted peers. The difference was attenuated and no longer significant when adjusting for measures of depression and attention-deficit/hyperactivity disorder. Results from a structural equation model indicated a full mediation effect of mental health problems on the association between adoption status and problematic alcohol and drug use. Our findings indicate that internationally adopted adolescents experience more problematic alcohol and drug use than their nonadopted peers, and the difference can largely be explained by mental health problems.

    The aim of the study was to investigate the relationship between body image and prevalence of underweight, normal weight, and overweight in adolescents. The study included 1702 girls and 1547 boys, aged 14-16 years, who completed questionnaire assessing body satisfaction. The participants' BMI status: underweight, normal weight or overweight was determined on the basis of BMI cut-off values. Results revealed that more girls (p < .001) showed low body satisfaction (44.8%) and fewer girls (p < .001) had high body satisfaction (17.6%) compared to boys (28.5% and 29.0%, respectively). A two-way ANOVA revealed a significant interaction between BMI status and gender on body satisfaction F(2, 3243) = 4.10, p = .017, η2 = .003. In boys, body satisfaction was higher in normal weight and underweight in comparison to overweight individuals (p < .001). Underweight girls presented higher body satisfaction than those who were normal weight and overweight (p < .001). Our findings indicated that, in relation to gender, BMI status can be associated with different body satisfaction in adolescents. This should be taken into consideration when designing programs aimed at obesity and disordered eating prevention and body image improvement. Due to the fact that underweight girls and boys have high body satisfaction, this can lead to behaviors that maintain low body weight in adolescents and in turn this may have negative health consequences.

    The 22q11.2 deletion syndrome (22q11.2DS) is associated with cognitive and functional impairments and increased risk for schizophrenia. We characterized multitasking abilities of adolescents with 22q11.2DS using an experimental naturalistic setting and examined whether multitasking impairments were associated with real-world functioning and negative symptoms. Thirty-nine adolescents (19 with 22q11.2DS and 20 controls) underwent the Multitasking Evaluation for Adolescents. Real-world functioning and clinical symptoms were assessed in participants with 22q11.2DS. Adolescents with 22q11.2DS performed poorly in the multitasking evaluation. Our data also suggest that multitasking abilities are related to adaptive functioning in the practical domain and negative symptoms. This study shows that adolescents with 22q11.2DS are characterized by multitasking impairments, which may be relevant for several aspects of the clinical phenotype.

    Knowing the prevalence and characteristics of auditory verbal hallucinations (AVH) in adolescents is important for estimations of need for mental health care and assessment of psychosis risk. In this report we assess the prevalence of AVH in a population-based sample of 16–19 years old Norwegian adolescents (n = 9,646, 46.4% male) using two items assessing AVH (from the extended Launay-Slade Hallucination Scale). The prevalence of hearing a voice speaking thoughts aloud was 10.6%. The prevalence of being troubled by voices was 5.3%, showing that negative emotionality about AVH is less frequent than the experience of hearing voices. Female respondents had slightly increased risk for being troubled by voices than males (odds ratio = 1.3), while age did not modulate prevalence. This AVH prevalence is in line with earlier reports in smaller samples of adolescents and indicates that AVH are not uncommon in this period of life. Further longitudinal studies are needed to investigate the value of AVH in predicting psychiatric disorder. PMID:25968251

    Study Objectives: To investigate cost-effectiveness of adolescent cognitive behavioral therapy for insomnia (CBTI) in group- and Internet-delivered formats, from a societal perspective with a time horizon of 1 y Methods: Costs and effects data up to 1-y follow-up were obtained from a randomized controlled trial (RCT) comparing Internet CBTI to face-to-face group CBTI. The study was conducted at the laboratory of the Research Institute of Child Development and Education at the University of Amsterdam, and the academic youth mental health care center UvAMinds in Amsterdam. Sixty-two participants meeting Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision criteria for insomnia were randomized to face-to-face group CBTI (GT; n = 31, age = 15.6 y ± 1.8, 71.0% girls) or individual Internet CBTI (IT; n = 31, age = 15.4 y ± 1.5, 83.9% girls). The intervention consisted of six weekly sessions and a 2-mo follow up booster-session of CBTI, consisting of psychoeducation, sleep hygiene, restriction of time in bed, stimulus control, cognitive therapy, and relaxation techniques. GT sessions were held in groups of six to eight adolescents guided by two trained sleep therapists. IT consisted of individual Internet therapy with preprogrammed content similar to GT, and guided by trained sleep therapists. Results: Outcome measures were subjective sleep efficiency (SE) ≥ 85%, and quality-adjusted life-years (QALY). Analyses were conducted from a societal perspective. Incremental cost-effectiveness ratios (ICERs) were calculated using bootstrap sampling, and presented in cost-effectiveness planes. Primary analysis showed costs over 1 y were higher for GT but effects were similar for IT and GT. Bootstrapped ICERs demonstrated there is a high probability of IT being cost-effective compared to GT. Secondary analyses confirmed robustness of results. Conclusions: Internet CBTI is a cost-effective treatment compared to group CBTI for adolescents, although

    Childhood maltreatment represents an important public health concern, as it is often associated with a host of negative outcomes across development. In recent years, researchers have begun to examine the link between negative health-related behaviors and history of childhood maltreatment. The current study considers the relationship between history of childhood maltreatment and sleep disturbances in adolescence. Further, the role of psychological distress is considered as an explanatory link between childhood maltreatment and adolescent sleep disturbances. The current study is a secondary analysis using a subsample (N=73) of child welfare-involved youth who participated in the initial and 2-year time-point of the Maltreatment and Adolescent Pathways (MAP) Longitudinal Study on the variables of interest. Youth reported on lifetime maltreatment experiences, psychological distress, and sleep disturbances, in addition to the other measures administered as part of the larger MAP study protocol. More severe childhood maltreatment was related to increased sleep disturbances during adolescence, and psychological distress was a significant mediator of the childhood maltreatment-adolescent sleep disturbance association. The results demonstrate that a history of childhood maltreatment represents a risk factor for sleep disturbances in adolescence. The findings highlight the importance of inquiring about health-related behaviors in child welfare youth and the need to promote psychological well-being within this population.

    Associations between brain structure and early adversity have been inconsistent in the literature. These inconsistencies may be partially due to methodological differences. Different methods of brain segmentation may produce different results, obscuring the relationship between early adversity and brain volume. Moreover, adolescence is a time of significant brain growth and certain brain areas have distinct rates of development, which may compromise the accuracy of automated segmentation approaches. In the current study, 23 adolescents participated in two waves of a longitudinal study. Family aggression was measured when the youths were 12 years old, and structural scans were acquired an average of 4 years later. Bilateral amygdalae and hippocampi were segmented using three different methods (manual tracing, FSL, and NeuroQuant). The segmentation estimates were compared, and linear regressions were run to assess the relationship between early family aggression exposure and all three volume segmentation estimates. Manual tracing results showed a positive relationship between family aggression and right amygdala volume, whereas FSL segmentation showed negative relationships between family aggression and both the left and right hippocampi. However, results indicate poor overlap between methods, and different associations were found between early family aggression exposure and brain volume depending on the segmentation method used.

    Little attention was paid to adolescents with Cancer in Spain up to 2010. In 2011 an "Adolescents with Cancer Committee" was established by the Spanish Society of Pediatric Hemato-Oncology (SEHOP) to care for the needs of these patients. The aim of this national survey was to outline the present situation of adolescents with cancer in Spanish Pediatric Hemato-Oncology units. A web based survey assessed institutional management of adolescents with cancer. The survey was personally sent to one member of the staff of each Pediatric Hemato-Oncology unit in Spain. It included questions about epidemiology, management, psycho-social coverage, specific facilities, and follow up of these patients. A total of 40 institutions out of 41 responded to the survey (overall response rate 98%). Fifty-six percent of the institutions had patients over 14, but only 36% of the institutions treated patients up to 18 years old. Only 25.6% of the units have more than 40 new pediatric cases every year. The percentage of patients between 14 and 18 years of age is below 10% in most of the units (77%). In 30.8% and 48.7% of the institutions, pediatric hemato-oncologists treat adolescents with hematological and solid tumors, respectively. The rest of the patients are seen by adult oncologists. There is only one institution that has a physician specifically dedicated to adolescent patients, and only two units have a "teenager's room". Only 2 units have a psychologist specifically trained to treat adolescents with cancer. The survey shows that most adolescents with cancer in Spain between 14 and 18 years of age are treated by adult oncologists. Most pediatric institutions still do not have specific facilities and psychosocial support for adolescents. The SEHOP is working hard in order to improve the quality of cancer care, and the quality of survival of this population.

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

    This 4-wave longitudinal study examines developmental changes in adolescents' perceptions of parent-adolescent relationships by assessing parental support, conflict with parents, and parental power. A total of 951 early adolescents (50.4% boys) and 390 middle adolescents (43.3% boys) participated. Univariate and multivariate growth curve analyses showed that support declined from early to middle adolescence for boys and girls and increased from middle to late adolescence for girls, while stabilizing for boys. Conflict was found to temporarily increase during middle adolescence. Parental power (relative power and dominance of parents) decreased from early to late adolescence. Results indicated that: (1) parent-adolescent relationships become more egalitarian during adolescence, (2) parents perceived by adolescents as powerful are viewed as supportive, especially in early adolescence, and (3) perceived conflict with parents is related to but not an impetus for changes in parent-adolescent relationships towards more equality.

    Childhood cutaneous melanoma is a rare disease with increasing incidence. It is not clear whether it differs from adult melanoma in etiology and clinical evolution. To genetically characterize childhood melanoma, 21 pediatric patients were studied by germ-line analysis of CDKN2A, CDK4, and MC1R genes. In addition, alterations in CDKN2A, c-Kit, BRAF, and NRAS genes were evaluated at the somatic level by direct gene sequencing, fluorescence in situ hybridization analysis, and immunohistochemistry. As a control group of susceptible patients, we studied patients from 23 melanoma-prone families. At the germ-line level, CDKN2A and MC1R gene variants were detected in 2/21 and 12/21 pediatric patients and in 9/23 and 19/22 in familial patients. At the somatic level, most lesions (9/14) from pediatric patients showed CDKN2A locus homozygous deletions and a null p16 immunophenotype, whereas most lesions (5/8) from familial patients were disomic and immunoreactive. A c-Kit low-polysomy profile seems to parallel CDKN2A homozygous deletions in pediatric melanoma whereas the single activating mutation observed segregates with familial patients. Loss of KIT protein expression was frequent (7/14) in pediatric melanomas, where metastatic cases were prevalent. BRAF(V600E) mutation occurred at a similar rate (approximately 50%) in lesions from pediatric and familial patients, whereas no NRAS mutations were detected.

    Recurrent dislocation of the patella is a common orthopaedic problem which occurs in about 44% of cases after first-time dislocation. In most cases of first-time patellar dislocation, the medial patellofemoral ligament (MPFL) becomes damaged. Between 2010 and 2012, 33 children and adolescents (39 knees) with recurrent patellar dislocation were treated with MPFL reconstruction using the adductor magnus tendon. The aim of our study is to assess the effectiveness of this surgical procedure. The outcomes were evaluated functionally (Lysholm knee scale, the Kujala Anterior Knee Pain Scale, and isokinetic examination) and radiographically (Caton index, sulcus angle, congruence angle, and patellofemoral angle). Four patients demonstrated redislocation with MPFL graft failure, despite the fact that patellar tracking was found to be normal before the injury, and the patients had not reported any symptoms. Statistically significant improvements in Lysholm and Kujala scales, in patellofemoral and congruence angle, were seen (P < 0.001). A statistically significant improvement in the peak torque of the quadriceps muscle and flexor was observed for 60°/sec and 180°/sec angular velocities (P = 0.01). Our results confirm the efficacy of MPFL reconstruction using the adductor magnus tendon in children and adolescents with recurrent patellar dislocation.

    Adolescent hallux valgus has a high recurrence rate after conventional surgical corrections. Excellent results have been reported with a double osteotomy of the first metatarsal fixed with a 3/16" transarticular pin. The present study reports the early results of using a medial plate and screws with an osteoperiosteal distally based flap to correct metatarsophalangeal joint subluxation, decrease recurrence from laxity in the medial capsular repair, and avoid intra-articular damage. The study included 18 feet in 16 patients (8 males, 8 females). All osteotomies healed primarily without complications, though there was recurrence in 3 undercorrected feet (2 patients). The average preoperative hallux valgus angle of 34 degrees was reduced to 16 degrees at a minimum 1-year follow-up. The average intermetatarsal angle improved from 14 degrees (before operation) to 6 degrees. No patient has requested plate removal.

    We aimed to investigate whether infants with myelomeningocele would improve their motor ability and functional independence after ten sessions of physical therapy and compare the outcomes of conventional physical therapy (CPT) to a physical therapy program based on reflex stimulation (RPT). Twelve children were allocated to CPT (n = 6, age 18.3 months) or RPT (n = 6, age 18.2 months). The RPT involved proprioceptive neuromuscular facilitation. Children were assessed with the Gross Motor Function Measure and the Pediatric Evaluation of Disability Inventory before and after treatment. Mann-Whitney tests compared the improvement on the two scales of CPT versus RPT and the Wilcoxon test compared CPT to RPT (before vs. after treatment). Possible correlations between the two scales were tested with Spearman correlation coefficients. Both groups showed improvement on self-care and mobility domains of both scales. There were no differences between the groups, before, or after intervention. The CPT and RPT showed similar results after ten weeks of treatment.

    2012-01-01

    Background Awareness of federal nutrition programs and use of the nutrition facts label are associated with reduced risk for obesity and increased intake of fruits and vegetables. Relationships between nutrition programs, use of food labels and risk for overweight and obesity have rarely been evaluated in adolescents. Methods Using the National Health and Nutrition Examination Survey from 2005–6, we evaluated the frequency of nutrition awareness of USDA and CDC nutrition programs and use of food labels in adolescents. Risk for overweight (BMI ≥ 85-94th percentile) and obesity (BMI ≥ 95th percentile) was assessed in relation to nutrition awareness and label reading. Results Most adolescents (92.4%) were aware of the Food Guide Pyramid. Fewer (43.5%) were aware of the 5-A-Day Program, and even less (29.3%) were aware of the Dietary Guidelines for Americans. Less than 25% of adolescents decided which foods to purchase by reading material on the nutrition facts label. There were significant racial and ethnic differences in awareness of federal nutrition programs with Mexican-Americans having the lowest levels of awareness of the US Dietary Guidelines for Americans and the Food Guide Pyramid in comparison with other groups. Non-Hispanic whites had higher and African-American adolescents had lower frequencies of reading fat information on the nutrition label in comparison to Mexican-American and other Hispanics. Awareness of other nutrition programs or of other information on the nutrition facts label was not associated with increased or decreased risk for overweight or obesity. Conclusions Use of the nutrition facts panel information is low among US adolescents. Additionally, less than half of adolescents are aware of federal nutrition programs including the Dietary Guidelines for Americans. Future studies should evaluate avenues to make nutrition information more accessible to young Americans. PMID:22639924

  9. Genomic and Enzymatic Results Show Bacillus cellulosilyticus Uses a Novel Set of LPXTA Carbohydrases to Hydrolyze Polysaccharides

    PubMed Central

    Mead, David; Drinkwater, Colleen; Brumm, Phillip J.

    2013-01-01

    Background Alkaliphilic Bacillus species are intrinsically interesting due to the bioenergetic problems posed by growth at high pH and high salt. Three alkaline cellulases have been cloned, sequenced and expressed from Bacillus cellulosilyticus N-4 (Bcell) making it an excellent target for genomic sequencing and mining of biomass-degrading enzymes. Methodology/Principal Findings The genome of Bcell is a single chromosome of 4.7 Mb with no plasmids present and three large phage insertions. The most unusual feature of the genome is the presence of 23 LPXTA membrane anchor proteins; 17 of these are annotated as involved in polysaccharide degradation. These two values are significantly higher than seen in any other Bacillus species. This high number of membrane anchor proteins is seen only in pathogenic Gram-positive organisms such as Listeria monocytogenes or Staphylococcus aureus. Bcell also possesses four sortase D subfamily 4 enzymes that incorporate LPXTA-bearing proteins into the cell wall; three of these are closely related to each other and unique to Bcell. Cell fractionation and enzymatic assay of Bcell cultures show that the majority of polysaccharide degradation is associated with the cell wall LPXTA-enzymes, an unusual feature in Gram-positive aerobes. Genomic analysis and growth studies both strongly argue against Bcell being a truly cellulolytic organism, in spite of its name. Preliminary results suggest that fungal mycelia may be the natural substrate for this organism. Conclusions/Significance Bacillus cellulosilyticus N-4, in spite of its name, does not possess any of the genes necessary for crystalline cellulose degradation, demonstrating the risk of classifying microorganisms without the benefit of genomic analysis. Bcell is the first Gram-positive aerobic organism shown to use predominantly cell-bound, non-cellulosomal enzymes for polysaccharide degradation. The LPXTA-sortase system utilized by Bcell may have applications both in anchoring

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

    This paper compares socioeconomic characteristics, prenatal care, and life styles of three groups of post-partum women, one consisting of adolescents (< 20 years) and the other two of women 20-34 years old, classified according to their history of pregnancy during adolescence. A sample of 3,508 post-partum women was selected from public hospitals in the city of Rio de Janeiro, Brazil, and interviewed just after childbirth. To verify the hypothesis of homogeneity of proportions, chi-square tests (chi2) were used. Comparing the three groups, the most adverse conditions were found among the 20-34-year-old mothers with a history of pregnancy during adolescence. These women have the least schooling, the highest rates of smoking and use of illegal drugs during pregnancy, and the fewest prenatal appointments. According to this study, prenatal care proved to be an effective compensatory policy for the prevention of prematurity and low birth weight, especially among adolescent mothers.

    Social affiliation is essential for many species and gains significant importance during adolescence. Disturbances in social affiliation, in particular social rejection experiences during adolescence, affect an individual’s well-being and are involved in the emergence of psychiatric disorders. The underlying mechanisms are still unknown, partly because of a lack of valid animal models. By using a novel animal model for social peer-rejection, which compromises adolescent rats in their ability to appropriately engage in playful activities, here we report on persistent impairments in social behavior and dysregulations in the endocannabinoid (eCB) system. From postnatal day (pd) 21 to pd 50 adolescent female Wistar rats were either reared with same-strain partners (control) or within a group of Fischer 344 rats (inadequate social rearing, ISR), previously shown to serve as inadequate play partners for the Wistar strain. Adult ISR animals showed pronounced deficits in social interaction, social memory, processing of socially transmitted information, and decreased pain sensitivity. Molecular analysis revealed increased CB1 receptor (CB1R) protein levels and CP55, 940 stimulated [35S]GTPγS binding activity specifically in the amygdala and thalamus in previously peer-rejected rats. Along with these changes, increased levels of the eCB anandamide (AEA) and a corresponding decrease of its degrading enzyme fatty acid amide hydrolase (FAAH) were seen in the amygdala. Our data indicate lasting consequences in social behavior and pain sensitivity following peer-rejection in adolescent female rats. These behavioral impairments are accompanied by persistent alterations in CB1R signaling. Finally, we provide a novel translational approach to characterize neurobiological processes underlying social peer-rejection in adolescence. PMID:27812328

    Data from a 2-year study describe tobacco use trends, perceptions, and prevention effects for 1,281 5th and 6th graders enrolled in 12 randomly selected Washington State elementary schools. Youths were pretested, then randomly divided by school into skills, discussion, and control groups. Preventive intervention curriculums for the skills and discussion groups included age-relevant information on smoked and smokeless tobacco use, peer testimonials, debates, games, and homework. Youths in the skills group also learned communication and problem-solving methods for handling difficult situations around tobacco use. Following intervention, youths were posttested, then retested semiannually for 2 years. During the 2-year study, three-quarters of all smokers and nonusers and half of all smokeless tobacco users maintained their statuses. Only 10 percent of all smokers and 3 percent of all smokeless users quit their habits. One in six reported new tobacco use, one-third of smokers began using smokeless tobacco, and two-thirds of all smokeless users began smoking during the study. Most youths at final measurement perceived smokeless tobacco as less of a health risk than smoking. Nearly one in two of all smokeless users intended to smoke, and two-thirds were actually smoking at 24-month followup. Both smoked and smokeless tobacco use rates increased in all groups, and youths in the skills intervention group consistently showed the lowest rates relative to the other groups. These findings demonstrate the potential of skills intervention methods for lowering tobacco use rates among adolescents. PMID:3090603

Participants selected from three options on the return of individual genomic results (RIR) and rated eight methods of re-contact. Most individuals with SCPs (77.8%) and non-SCP controls (72.5%) wanted RIR involving health or behavioral implications. The majority of individuals with SCPs (67.2%) and non-SCP controls (69.7%) indicated that phone re-contact was ‘best’, with e-mail (22.5% SCPs, 33.9% non-SCPs) and social networking websites (21.3% SCPs, 20.2% non-SCPs) being viable options. These results suggest a layered approach for RIR: phone calls, followed by e-mails and a secure message to a social networking account. Data from this special and vulnerable population, which includes youth involved in the criminal justice system and substantial minority participation, bring an essential and missing perspective to the discussion of RIR.

The final sample consisted of 3,897 adolescents between 12 and 17 years old (M=14.45, SD=1.59), 1,836 males and 2,049 females, recruited from 39 secondary schools in the east of Spain. The Cuestionario de victimización juvenil mediante internet y/o teléfono móvil (hereinafter, Juvenile Online Victimization Questionnaire, JOV-Q, Montiel & Carbonell, 2012) was applied for the assessment of eight types of online victimization grouped in two major domains: sexual (sexual coercion, sexual pressure, online grooming by an adult, unwanted exposure to sexual content and violation of privacy); and nonsexual victimization (online harassment, happy slapping, pressure to obtain personal information). Sixty-one percent of adolescents reported online victimization during the last year. Online sexual victimization was reported by 39.5% of adolescents and nonsexual victimization by 53.4% of them, whereas 31% of youth reported having experienced online victimization in both domains. The highest prevalence rates were recorded for online harassment (50%), unwanted exposure to sexual content (24.4%), pressure to obtain personal information (18.4%) and online grooming by an adult (17.2%), and the lowest for sexual coercion (6.7%) and happy slapping (2.2%). Thirty-five percent of the adolescents were considered online polyvictims and most of them experienced victimization in both sexual and nonsexual domains (88%). This study illustrates that Spanish adolescents experience high levels of online victimization and that multiple online victimization appears to be the norm among cybervictims.

    The aim of the current study was to assess the association between sleep duration and sleep patterns and academic performance in 16-19 year-old adolescents using registry-based academic grades. A large population-based study from Norway conducted in 2012, the youth@hordaland-survey, surveyed 7798 adolescents aged 16-19 years (53.5% girls). The survey was linked with objective outcome data on school performance. Self-reported sleep measures provided information on sleep duration, sleep efficiency, sleep deficit and bedtime differences between weekday and weekend. School performance [grade point average (GPA)] was obtained from official administrative registries. Most sleep parameters were associated with increased risk for poor school performance. After adjusting for sociodemographic information, short sleep duration and sleep deficit were the sleep measures with the highest odds of poor GPA (lowest quartile). Weekday bedtime was associated significantly with GPA, with adolescents going to bed between 22:00 and 23:00 hours having the best GPA. Also, delayed sleep schedule during weekends was associated with poor academic performance. The associations were somewhat reduced after additional adjustment for non-attendance at school, but remained significant in the fully adjusted models. In conclusion, the demonstrated relationship between sleep problems and poor academic performance suggests that careful assessment of sleep is warranted when adolescents are underperforming at school. Future studies are needed on the association between impaired sleep in adolescence and later functioning in adulthood.

    Cigna's Collaborative Accountable Care initiative provides financial incentives to physician groups and integrated delivery systems to improve the quality and efficiency of care for patients in commercial open-access benefit plans. Registered nurses who serve as care coordinators employed by participating practices are a central feature of the initiative. They use patient-specific reports and practice performance reports provided by Cigna to improve care coordination, identify and close care gaps, and address other opportunities for quality improvement. We report interim quality and cost results for three geographically and structurally diverse provider practices in Arizona, New Hampshire, and Texas. Although not statistically significant, these early results revealed favorable trends in total medical costs and quality of care, suggesting that a shared-savings accountable care model and collaborative support from the payer can enable practices to take meaningful steps toward full accountability for care quality and efficiency.

    Objective The purpose of this randomized trial was to investigate the efficacy of two behavioral treatments focusing on different change mechanisms in ameliorating a borderline personality disorder constellation of behaviors and substance use in adolescents referred by juvenile diversion programs. Methods Forty adolescents 14 to 17 years of age and meeting DSM IV criteria for borderline personality disorder and substance use disorders were randomized to Integrative Borderline Personality Disorder-Oriented Adolescent Family Therapy (I-BAFT) or Individual Drug Counseling (IDC). This design allowed a comparison of two manualized interventions, one family-based and one individually-oriented. Profiles of clinical change were used to detect impact and to estimate treatment effect sizes. Results Primary analyses showed that both interventions had a clinically significant impact on borderline personality disorder behaviors 12 months after baseline but with no differential treatment effects. The impact on substance use was more complex. Subgroup analyses revealed that adolescents with depression had significantly more severe profiles of borderline personality disorder and substance use. These youth were the only group to show reductions in substance use, but only if they received the I-BAFT intervention. Study data also documented the high dosage of intensive residential treatment needed by this population. Conclusions and Implications for Practice Results highlight the intensive treatment needs of juvenile justice involved youth with co-occurring substance use and borderline personality disorder including depression, the hybrid outpatient and residential treatment often required by this population, and the promise of a family oriented approach particularly for youth with severe symptoms and co-occurring depression.

    Emotional variability reflects the ability to flexibly switch among a broad range of positive and negative emotions from moment-to-moment during interactions. Emotional variability during mother-adolescent conflict interactions is considered to be important for healthy socio-emotional functioning of mothers and adolescents. The current observational study examined whether dyadic emotional variability, maternal emotional variability, and adolescent emotional variability during conflict interactions in early adolescence predicted mothers' and adolescents' internalizing problems five years later. We used data from 92 mother-adolescent dyads (Mage T1 = 13.05; 65.20 % boys) who were videotaped at T1 while discussing a conflict. Emotional variability was derived from these conflict interactions and it was observed for mother-adolescent dyads, mothers and adolescents separately. Mothers and adolescents also completed questionnaires in early adolescence (T1) and five years later in late adolescence (T6) on mothers' internalizing problems, and adolescents' anxiety and depressive symptoms. Hierarchical regression analyses showed that less dyadic emotional variability in early adolescence predicted relative increases in mothers' internalizing problems, adolescents' depressive symptoms, and adolescents' anxiety symptoms from early to late adolescence. Less maternal emotional variability only predicted relative increases in adolescents' anxiety symptoms over time. The emotional valence (e.g., types of emotions expressed) of conflict interactions did not moderate the results. Taken together, findings highlighted the importance of considering limited emotional variability during conflict interactions in the development, prevention, and treatment of internalizing problems of mothers and adolescents.

    This study investigated the relationship between academic factors and past-year alcohol, cigarette, and marijuana use in an adolescent sample of Latinos. Secondary data analysis was conducted using a subsample of Latino adolescents (N=2,593) from the 2006 National Survey on Drug Use and Health. School connectedness and parental involvement in school were protective across all substances. Fighting in school increased the risk for use of all substances, and failing grades increased the risk for alcohol and marijuana use. Implications for prevention include the development of prevention programs that aim to increase students' connection to school and increase parental involvement.

    A handful of prior adoption studies have confirmed that the cross-sectional relationship between child conduct problems and parent/child conflict is at least partially shared environmental in origin. However, as the direction of causation between parenting and delinquency remains unclear, this relationship could be better explained by the adolescent's propensity to elicit conflictive parenting, a phenomenon referred to as an evocative gene-environment correlation. The current study thus examined the prospective relationship between conduct problems and parent-child conflict in a sample of adoptive families. Participants included 672 adolescents in 405 adoptive families assessed at two time points roughly 4 years apart. Results indicated that parent-child conflict predicts the development of conduct problems, whereas conduct problems do not predict increases in parent-child conflict. Such findings suggest that evocative gene-environment correlations are highly unlikely as an explanation of prior shared environmental effects during adolescence. Moreover, because the adolescents in this study do not share genes with their adoptive parents, the association between conduct problems and parent-child conflict is indicative of shared environmental mediation in particular. Implications of our findings are discussed. PMID:21038930

    AIM To compare the outcomes of displaced distal radius fractures treated with volar locking plates and with immediate postoperative mobilisation with the outcomes of these fractures treated with modalities that necessitate 6 wk wrist immobilisation. METHODS A prospective, randomised controlled single-centre trial was conducted with 56 patients who had a displaced radius fracture were randomised to treatment either with a volar locking plate (n = 29), or another treatment modality (n = 27; cast immobilisation with or without wires or external fixator). Outcomes were measured at 12 wk. Functional outcome scores measured were the Patient-Rated Wrist Evaluation (PRWE) Score; Disabilities of the Arm, Shoulder and Hand and activities of daily living (ADLs). Clinical outcomes were wrist range of motion and grip strength. Radiographic parameters were volar inclination and ulnar variance. RESULTS Patients in the volar locking plate group had significantly better PRWE scores, ADL scores, grip strength and range of extension at three months compared with the control group. All radiological parameters were significantly better in the volar locking plate group at 3 mo. CONCLUSION The present study suggests that volar locking plates produced significantly better functional and clinical outcomes at 3 mo compared with other treatment modalities. Anatomical reduction was significantly more likely to be preserved in the plating group. Level of evidence: II. PMID:27795951

    This research evaluated a multivariate approach as an alternative tool for the purpose of selection regarding expected progeny differences (EPDs). Data were fitted using a multi-trait model and consisted of growth traits (birth weight and weights at 120, 210, 365 and 450 days of age) and carcass traits (longissimus muscle area (LMA), back-fat thickness (BF), and rump fat thickness (RF)), registered over 21 years in extensive breeding systems of Polled Nellore cattle in Brazil. Multivariate analyses were performed using standardized (zero mean and unit variance) EPDs. The k mean method revealed that the best fit of data occurred using three clusters (k = 3) (P < 0.001). Estimates of genetic correlation among growth and carcass traits and the estimates of heritability were moderate to high, suggesting that a correlated response approach is suitable for practical decision making. Estimates of correlation between selection indices and the multivariate index (LD1) were moderate to high, ranging from 0.48 to 0.97. This reveals that both types of indices give similar results and that the multivariate approach is reliable for the purpose of selection. The alternative tool seems very handy when economic weights are not available or in cases where more rapid identification of the best animals is desired. Interestingly, multivariate analysis allowed forecasting information based on the relationships among breeding values (EPDs). Also, it enabled fine discrimination, rapid data summarization after genetic evaluation, and permitted accounting for maternal ability and the genetic direct potential of the animals. In addition, we recommend the use of longissimus muscle area and subcutaneous fat thickness as selection criteria, to allow estimation of breeding values before the first mating season in order to accelerate the response to individual selection.

    Introduction Sporting activities differ in their ability to promote moderate-to-vigorous physical activity (MVPA). To assess adolescents’ engagement in sport under field conditions we used accelerometers to measure their MVPA levels during sport. We pay special attention to differences between team and individual sport and between common sports. Methods Diary data and 7-day accelerometry from 1054 Germans ages 15–17 were combined to measure physical activity. 1373 diaried episodes of more than 40 common sports were identified from 626 participants and grouped into team and individual sport. We modeled the effect of team and individual sport, and described levels of MVPA and episodes of no MVPA for all recorded sports. Results German boys and girls averaged 43 (SD 21) and 37 (SD 24) minutes MVPA per day. Boys got 2.2 times as much MVPA per minute during team compared to individual sport (p<0.0001) but there was no significant difference for girls. Percent of time spent in MVPA during sport ranged from 6% for weight training to 74% for jogging, with individual sports averaging 10–30% and team sports 30–50%. 11% of sport episodes had no MVPA: half of episodes of cycling, 5% of jogging, and none for tennis or badminton. An episode of individual sport was 17 times more likely to have no MVPA than an episode of team sport (p<0.0001). Conclusion Under field condition, adolescents were active for only a fraction of diaried sporting time. As measured by accelerometry, individual sport often produced no MVPA. Characteristics of the sport, such as team vs. individual, were more predictive of MVPA than were characteristics of the participant, such as background activity levels. PMID:26291984

    Objective To determine the effectiveness of brief strategic family therapy (BSFT; an evidence-based family therapy) compared to treatment as usual (TAU) as provided in community-based adolescent outpatient drug abuse programs. Method A randomized effectiveness trial in the National Drug Abuse Treatment Clinical Trials Network compared BSFT to TAU with a multiethnic sample of adolescents (213 Hispanic, 148 White, and 110 Black) referred for drug abuse treatment at 8 community treatment agencies nationwide. Randomization encompassed both adolescents’ families (n = 480) and the agency therapists (n = 49) who provided either TAU or BSFT services. The primary outcome was adolescent drug use, assessed monthly via adolescent self-report and urinalysis for up to 1 year post randomization. Secondary outcomes included treatment engagement (≥2 sessions), retention (≥8 sessions), and participants’ reports of family functioning 4, 8, and 12 months following randomization. Results No overall differences between conditions were observed in the trajectories of self-reports of adolescent drug use. However, the median number of days of self-reported drug use was significantly higher, χ2(1) = 5.40, p < .02, in TAU (Mdn = 3.5, interquartile range [IQR] = 11) than BSFT (Mdn = 2, IQR = 9) at the final observation point. BSFT was significantly more effective than TAU in engaging, χ2(1) = 11.33, p < .001, and retaining, χ2(1) = 5.66, p < .02, family members in treatment and in improving parent reports of family functioning, χ2(2) = 9.10, p < .011. Conclusions We discuss challenges in treatment implementation in community settings and provide recommendations for further research. PMID:21967492

    The findings about the shapes of associations between sleep duration and overweight/obesity in adolescents were largely inconsistent in the existing literature. We examined the functional forms of the associations between sleep duration and overweight/obesity in 66,817 Chinese adolescents by modelling sleep duration categorically and continuously. The adjusted ORs (95% CI) of overweight (with 7.0-8.9 h of sleep being considered the reference group) for subjects reporting <5.0 hours, 5.0-6.9 hours and ≥9.0 hours of sleep were 1.26 (1.05-1.51), 1.06 (1.00-1.11) and 1.27 (1.14-1.42), respectively. The adjusted ORs (95% CI) of obesity (with 7.0-8.9 h of daily sleep being considered as the reference group) for adolescents reporting <5.0 hours, 5.0-6.9 hours and ≥9.0 hours of sleep were 1.24 (0.97-1.57), 0.94 (0.87-1.01) and 1.42 (1.24-1.63), respectively. Continuous splines regressions support non-linear U shape associations between sleep duration and overweight/obesity, with the bottom at around 7.0-8.0 hours sleep (overweight: likelihood ratio = 32.7 p < 0.01; obesity: likelihood ratio = 40.4 p < 0.01). U-shape associations were found between sleep duration and overweight/obesity in Chinese adolescents and an optimal sleep duration of 7.0-8.0 hours sleep may prevent overweight/obesity.

    To maximize scarce intervention dollars, pediatricians and other adolescent health professionals must position health promotion efforts in mediums that most effectively reach youth. This may be especially true in resource-limited settings where access to primary health care and medications is limited. To improve the efficiency and impact of disease prevention and health promotion efforts in resource-limited settings, we examine sources of health information cited by adolescents in Mbarara Uganda. Participants in the Uganda Media and You survey were students aged 12-18 (n = 500) randomly identified in five secondary schools in Mbarara municipality, Uganda. Ninety-three percent of eligible and invited youth completed the cross-sectional, pencil-and-paper survey. Four in five adolescents (81%) indicated they turned to parents, teachers, and other adults while around half read a book/went to the library (56%) or turned to siblings and friends (50%) for information about health and disease. More than one in three (38%) indicated that they used the computer and Internet to search for health information. Older versus younger respondents tended to rely upon siblings and friends for all types of health questions. On the other hand, younger versus older youth were significantly more likely to turn to parents, teachers, and other adults for their questions about sexual health. Adults may be an important component of effective disease prevention and health promotion campaigns. Multiple delivery methods may be especially effective for reaching older adolescents. Technology also may be an important health promotion tool in resource-limited settings.

The follow-up period was 4 years (2008-2012). The 20-item Toronto Alexithymia Scale (TAS-20) was used for the assessment of alexithymia both at baseline and follow-up. The Multidimensional Scale of Perceived Social Support (MSPSS) and the Parental Bonding Instrument (PBI) were used as measures at baseline. Regarding absolute stability, the changes in the TAS-20 total scores and two subscales (DIF and EOT) were statistically significant but the effect sizes for the changes were small (Cohen׳s d 0.21-0.24). The test-retest correlations for the TAS-20 total and subscale scores were high (ρ=0.50-0.64, P<0.001), indicating relative stability. While several parental and social support variables were associated with alexithymia at baseline, low social support from friends was the only to predict higher alexithymia at follow-up. Alexithymia is a stable personality trait also in late adolescence. Low social support from friends is related to alexithymia in young adulthood.

    The prevalence of adolescent anemia, iron deficiency and thalassemia were examined in 2 provinces of northeast Thailand. Blood specimens were collected from adolescent subjects aged 15-17 years in 2 areas; 185 (85 males and 100 females) in Mukdahan province and 313 (116 males and 197 females) in Roi-Et. RBC parameters, serum ferritin levels, Hb and DNA analyses for the identification of common thalassemia genes in Thailand were investigated. The prevalences of anemia were found to be 21.1% (8.1 in male and 13.0 in female) and 16.6% (8.9 in male and 7.7 in female) in Mukdahan and Roi-Et province, respectively. Iron deficiency was observed to be 24.3% in Mukdahan and 14.7% in Roi-Et. Various types of thalassemia were identified in 62.2 and 58.8% of the subject populations, respectively. The proportions of iron deficiency, thalassemia and combined thalassemia and iron deficiency among anemic subjects were 10.2, 53.8 and 30.8% in Mukdahan, and 7.7, 67.3 and 9.6% in Roi-Et. Hematological characteristics were analyzed and are presented. It is concluded that thalassemia and hemoglobinopathies rather than iron deficiency are major causes of adolescent anemia which should be taken into account in public health strategies for the control of anemia in the region.

    BACKGROUND: This paper reports findings from a field experiment that evaluated mass media campaigns designed to prevent cigarette smoking by adolescents. METHODS: The campaigns featured radio and television messages on expected consequences of smoking and a component to stimulate personal encouragement of peers not to smoke. Six Standard Metropolitan Statistical Areas in the Southeast United States received campaigns and four served as controls. Adolescents and mothers provided pretest and posttest data in their homes. RESULTS AND CONCLUSIONS: The radio campaign had a modest influence on the expected consequences of smoking and friend approval of smoking, the more expensive campaigns involving television were not more effective than those with radio alone, the peer-involvement component was not effective, and any potential smoking effects could not be detected.

    The psychological construct broadly known as time perspective is potentially useful in understanding a range of adolescent behaviours, including alcohol use. However, the utility of the construct has been hindered by measurement and conceptual problems. To date the vast majority of studies have assessed the relationship between time perspective and other measures in a variable-focussed (correlational) rather than a person-centred way. The present series of studies used a person-centred approach to assess the relationship between temporal profiles and alcohol use in a large sample (n = 1620) of adolescents from High Schools in Northern Ireland. Although a 'Balanced' time perspective has been suggested as optimal, the present study suggests that having a 'Future' temporal profile is associated with less problematic use of alcohol, while having a 'Past Negative' or 'Hedonist' profile is associated with more problematic consumption. Results are discussed in the context of the time perspective and alcohol use literatures.

    Tonga has a very high prevalence of obesity with steep increases during youth, making adolescence a critical time for obesity prevention. The Ma'alahi Youth Project, the Tongan arm of the Pacific Obesity Prevention in Communities project, was a 3-year, quasi-experimental study of community-based interventions among adolescents in three districts on Tonga's main island (Tongatapu) compared to the island of Vava'u. Interventions focused mainly on capacity building, social marketing, education and activities promoting physical activity and local fruit and vegetables. The evaluation used a longitudinal design (mean follow-up duration 2.4 years). Both intervention and comparison groups showed similar large increases in overweight and obesity prevalence (10.1% points, n = 815; 12.6% points, n = 897 respectively). Apart from a small relative decrease in percentage body fat in the intervention group (-1.5%, P < 0.0001), there were no differences in outcomes for any anthropometric variables between groups and behavioural changes did not follow a clear positive pattern. In conclusion, the Ma'alahi Youth Project had no impact on the large increase in prevalence of overweight and obesity among Tongan adolescents. Community-based interventions in such populations with high obesity prevalence may require more intensive or longer interventions, as well as specific strategies targeting the substantial socio-cultural barriers to achieving a healthy weight.

    Our objective was to evaluate the effectiveness of a long-acting formulation of methylphenidate (MPH-SODAS) on attention-deficit/hyperactivity disorder (ADHD) symptoms in an outpatient sample of adolescents with ADHD and substance use disorders (SUD). Secondary goals were to evaluate the tolerability and impact on drug use of MPH-SODAS. This was a 6-week, single-blind, placebo-controlled crossover study assessing efficacy of escalated doses of MPH-SODAS on ADHD symptoms in 16 adolescents with ADHD/SUD. Participants were randomly allocated to either group A (weeks 1-3 on MPH-SODAS, weeks 4-6 on placebo) or group B (reverse order). The primary outcome measures were the Swanson, Nolan and Pelham Scale, version IV (SNAP-IV) and the Clinical Global Impression Scale (CGI). We also evaluated the adverse effects of MPH-SODAS using the Barkley Side Effect Rating Scale and subject reports of drug use during the study. The sample consisted of marijuana (N = 16; 100%) and cocaine users (N = 7; 43.8%). Subjects had a significantly greater reduction in SNAP-IV and CGI scores (P < 0.001 for all analyses) during MPH-SODAS treatment compared to placebo. No significant effects for period or sequence were found in analyses with the SNAP-IV and CGI scales. There was no significant effect on drug use. MPH-SODAS was well tolerated but was associated with more severe appetite reduction than placebo (P < 0.001). MPH-SODAS was more effective than placebo in reducing ADHD symptoms in a non-abstinent outpatient sample of adolescents with comorbid SUD. Randomized clinical trials, with larger samples and SUD intervention, are recommended.

    Although gay, lesbian, and bisexual (GLB) adolescents face many of the same developmental challenges as do heterosexual adolescents, they must also deal with the stress of being part of a stigmatized group. The purpose of this study was to examine the extent to which family support and involvement with the queer community may buffer the effects of life stress on substance use among GLB youths. Drawing on a large national online survey, the authors examined drug use in 1906 GLB youths 12 to 17 years of age. Overall, 20 percent of the youths reported using illegal substances in the past 30 days. Results from multivariate analyses revealed that stress, as measured by suicidal ideation, significantly increased the risk of drug use. A positive reaction from the mother to the youth's coming out served as a significant protective factor, whereas involvement in a queer youth group had no effect. The authors found evidence that, for GLB adolescents, parental acceptance of sexual identity is an important aspect of a strong family relationship and, thus, has important ramifications for their healthy development. Implications of the findings for social work practice are discussed.

    Study design A prospective treatment study with a new brace was conducted Objective. To evaluate radiological and subjective clinical results after one year conservative brace treatment with pressure onto lordosis at the thoracolumbar joint in children with scoliosis and kyphosis. Summary of background data Conservative brace treatment of adolescent scoliosis is not proven to be effective in terms of lasting correction. Conservative treatment in kyphotic deformities may lead to satisfactory correction. None of the brace or casting techniques is based on sagittal forces only applied at the thoracolumbar spine (TLI= thoracolumbar lordotic intervention). Previously we showed in patients with scoliosis after forced lordosis at the thoracolumbar spine a radiological instantaneous reduction in both coronal curves of double major scoliosis. Methods A consecutive series of 91 children with adolescent scoliosis and kyphosis were treated with a modified symmetric 30 degrees Boston brace to ensure only forced lordosis at the thoracolumbar spine. Scoliosis was defined with a Cobb angle of at least one of the curves [greater than or equal to] 25 degrees and kyphosis with or without a curve <25 degrees in the coronal plane. Standing radiographs were made i) at start, ii) in brace at beginning and iii) after one year treatment without brace. Results Before treatment start ‘in brace’ radiographs showed a strong reduction of the Cobb angles in different curves in kyphosis and scoliosis groups (sagittal n = 5 all p < 0.001, pelvic obliquity p < 0.001). After one year of brace treatment in scoliosis and kyphosis group the measurements on radiographs made without brace revealed an improvement in 3 Cobb angles each. Conclusion Conservative treatment using thoracolumbar lordotic intervention in scoliotic and kyphotic deformities in adolescence demonstrates a marked improvement after one year also in clinical and postural criteria.

    Background There is an urgent need for innovative and developmentally appropriate lifestyle interventions to promote healthy lifestyle behaviors and to prevent the early onset of type 2 diabetes and cardiovascular disease risk in obese Latino adolescents. Guided imagery offers promise to reduce stress and promote lifestyle behavior change to reduce disease risk in obese adolescents. Our objectives were: 1) To pilot test a new 12-wk lifestyle intervention using a randomized trial design in obese Latino adolescents, in order to determine the effects of the mind-body modality of Interactive Guided ImagerySM (IGI), over and above those of a didactic lifestyle education, on insulin resistance, eating and physical activity behaviors, stress and stress biomarkers; and 2) To explore the role of intervention-related changes in stress and stress biomarkers on changes in metabolic outcomes, particularly insulin resistance. Methods Obese (BMI > 95th percentile), Latino adolescents (n = 35, age 14-17) were randomized to receive either 12 weekly sessions of a lifestyle education plus guided imagery program (GI), or lifestyle education plus a digital storytelling computer program (DS). Between-group differences in behavioral, biological, and psychological outcomes were assessed using unpaired T-tests and ANCOVA in the 29 subjects who completed the intervention. Results The GI group demonstrated significant reductions in leisure sedentary behavior (p < .05) and increases in moderate physical activity (p < .05) compared to DS group, and a trend toward reduced caloric intake in GI vs DS (p = .09). Salivary cortisol was acutely reduced by stress-reduction guided imagery (p < .01). There were no group differences in adiposity, insulin resistance, perceived stress, or stress biomarkers across the 12-week intervention, though decrease in serum cortisol over the course of the intervention was associated with improved insulin sensitivity (p = .03) independent

    Low concentrations of the neurotransmitter serotonin and its 5-hydroxyindoleacetic acid metabolite in the central nervous system have been associated with increased aggressive behavior in animals and humans. Controlled clinical trials of serotonin agonists in depressed adults have suggested that aggressive behavior is less likely during treatment with these medications than with placebo, but there have been no previous studies of selective serotonin reuptake inhibitors (SSRIs) and aggression in children. We prospectively followed the course of aggressive behavior in 19 psychiatrically hospitalized adolescents (not selected for aggressiveness) who received open clinical trials of fluoxetine, paroxetine, or sertraline. The patients received standard doses (equivalent to fluoxetine 10-40 mg daily) for a minimum of 5 weeks. The starting dose was 15 +/- 5 mg, and dosages were raised at a mean rate of 5 mg every 4 days up to a mean dose of 25 +/- 10 mg daily. Results from trials of the three SSRIs were clustered because the sample sizes were not sufficient for separate analyses. Overall, there were no statistically meaningful improvements in the level of aggressive behavior, as measured on a modified version of the Overt Aggression Scale, over the course of these patients' SSRI trials. Symptoms of physical aggression toward others or self were manifest in 12 of the 19 patients while on SSRIs. Of the 19 patients, 13 were assessed both on and off SSRIs: verbal aggression (p = 0.04), physical aggression toward objects (p = 0.05), and physical aggression toward self (p < 0.02) occurred significantly more frequently on SSRIs than off; no increase was observed in physical aggression toward others. Patients with the highest baseline aggressivity scores did not show greater improvement during SSRI treatment. Further research is warranted, particularly to explore whether SSRIs may have therapeutic effects on aggression at higher (or lower) doses than were administered in this

    Purpose The purpose of this study is to develop and pilot an innovative behavioral intervention in adolescents with type 1 diabetes mellitus (T1DM) incorporating structured care of a pet to improve glycemic control. Methods 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. Results After 3 months the participants in the intervention group exhibited a statistically significant decrease in A1C levels (−0.5%) compared to their peers in the control group who had an increase in A1C levels (0.8%)(p = 0.04). The younger adolescents (ages 10–13) demonstrated a greater response to the intervention which was statistically significant (−1.5% vs. 0.6%, p = 0.04) compared with the older adolescents (ages 14–17). Conclusions Structured care of a pet fish can improve glycemic control in adolescents with T1DM, likely by providing cues to perform diabetes self-management behaviors. PMID:25614529

    Physical activity during childhood and adolescence has numerous health benefits, while sedentary behavior, especially electronic media use, is associated with the development of overweight. Therefore, the promotion of physical activity during childhood and adolescence is an integral part of national public health efforts. The aim of this article is to describe the physical activity behavior of German children and adolescents based on the nationwide data of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS wave 1). Furthermore, the association between physical activity and sports participation and use of screen-based media in youth aged 11 to 17 years was analyzed. The analyses included data from 10,426 children and adolescents aged 3-17 years collected by telephone interviews. Children older than 11 years answered the questions by themselves, whereas a parent was interviewed for younger children. The descriptive analyses were performed under consideration of social and demographic factors. According to the results of KiGGS wave 1 a total of 77.5% (95% Cl 76.0-78.9 %) of the children and adolescents participated in sports activities, and 59.7% (58.1-61.3 %) were members of a sports club. The recommendation of the World Health Organization (WHO) to be physically active at least 60 min per day was achieved by 27.5% (26.0-28.9 %). Children and adolescents with a low socioeconomic status (SES) participated less in sports activities than children of higher SES groups. Excessive use of screen-based media was more likely to be associated with lack of sports participation than with a lack of physical activity. In the future, preventive measures should promote the daily physical activity of children and adolescents and additionally encourage children and adolescents with low SES to participate in sports activities.

    Poor school-functioning can be indicative of parent and adolescent mental health and adolescent behavior problems. This study examined 472 adolescents enrolled in the World Trade Center (WTC) Health Registry, with a two-step path analysis, using regression-based models, to unravel the relationships between parent and adolescent mental health, adolescent behavior problems, and adolescent unmet healthcare need (UHCN) on the outcome school-functioning. WTC exposure was associated with UHCN and parental mental health was a significant mediator. There was no evidence that family WTC exposure was associated with UHCN independent of its effect on parental mental health. For the second path, after accounting for the effects of adolescent mental health, behavioral problems, and UHCN, there remained a significant association between parental mental health and school-functioning. Interventions for poor school-functioning should have multiple components which address UHCN, mental health, and behavioral problems, as efforts to address any of these alone may not be sufficient.

    2015-01-01

    Background: Epidemiological studies have reported associations between lung function parameters and organophosphate (OP) pesticide exposures in agricultural occupations, but to our knowledge associations have not been evaluated in general populations. Objectives: We examined associations between OP metabolite dialkyl phosphates (DAPs) and lung function using data from the Canadian Health Measures Survey (CHMS) Cycle 1. Methods: Forced vital capacity (FVC), forced expiratory volume in 1 sec (FEV1), FEV1/FVC ratio, and forced expiratory flow between 25% and 75% of FVC (FEF25%–75%) were measured for 4,446 CHMS participants. Urinary concentrations of six DAP metabolites (DMP, DMTP, DMDTP, DEP, DETP, and DEDTP), smoking status, and other predictors of lung function were also measured in the CHMS-Cycle 1. Multiple linear regression analyses were used to examine the relationship between total DAP concentrations (ΣDAPs) and lung function in adolescents (12–19 years) and adults (20–79 years). Results: In adults, estimates from multiple regression analyses suggested that a 1-unit increase on natural logarithmic scale (171% increase on the original scale) in the creatinine-corrected urinary concentration (nanomoles per gram creatinine) of ΣDAP was associated with a 32.6-mL (95% CI: –57.2, –8.1) reduction in FVC, 32.6-mL (95% CI: –59.0, –6.3) reduction in FEV1, 0.2% (95% CI: –0.6, 0.2) reduction in FEV1/FVC ratio, and 53.1-mL/sec (95% CI: –113.9, 7.7) reduction in FEF25%–75%. In adolescents, associations between ΣDAP and FEV1 were closer to the null and positive for FVC, whereas associations with FEV1/FVC and FEF25%–75% were negative, as in adults. However, none of the associations were significant in adolescents. Conclusions: The negative association between ΣDAP and lung function in adult participants suggests a detrimental effect of OP pesticides on lung function in the adult general population. Further studies using prospective designs are

    1991-06-01

    This study examined the individual characteristics, family relations, and stress/social support of 50 maltreated adolescents and their mothers. Dyads were divided into 4 demographically similar groups: neglect, physical abuse, sexual abuse, and nonmaltreatment control. Results show that adolescent neglect was primarily associated with extrafamilial difficulties and social isolation. Adolescent physical abuse was linked more with rigidity in family relations, poorer maternal understanding of child developmental skills, and adolescent externalizing behaviors. In contrast, adolescent sexual abuse was related to maternal emotional problems and adolescent internalizing behaviors. In general, each group of maltreated adolescents experienced lower levels of family cohesion, more attention problems, and more daily stress than did their nonmaltreated counterparts. Findings are consistent with an ecological model of adolescent maltreatment.

    At a young age, health care is mainly provided by doctors in private practice. In this study, the health care of children and adolescents in Thuringia is analysed. Data base is the federal state module Thuringia (2010-2012, n = 4884; 0-17 years), which was conducted by the Robert Koch Institute as part of KiGGS wave 1 (2009-2012). The health care of children and adolescents is described based on 7 indicators: total medical visits, paediatrician visits, general practitioner visits, hospitalisation, health screening examinations and vaccination against human papillomavirus (HPV). Prevalence and mean values with 95 % confidence intervals were reported, and with logistic and linear regressions, the significance of the group differences was examined. Results show that 93.9 % of children and adolescents aged 0-17 years in Thuringia went in the last 12 months to doctors in private practice; the average number of doctor visits was 6.6 contacts. 75.1 % of 0‑ to 17-year-olds were treated by a paediatrician, and 29.9 % visited a general practitioner. In addition, 13.1 % of 0‑ to 17-year-olds in Thuringia have spent at least one night in hospital in the last 12 months; the average number of hospital nights was 7.2. With 90.5 %, the majority of the children aged 7-13 years completed the health screening program for children (U3-U9, without U7a). 67.5 % of the 14- to 17-year-old girls were vaccinated against HPV with at least one dose (lifetime prevalence), and 56.3 % have received a full vaccination with 3 doses. In addition, 62.0 % of 14- to 17-year-old girls went at least once to a gynaecologist. There are significant differences by gender, age, socio-economic status and place of residence (urban/rural). In summation, the results indicate a high utilisation rate by children and adolescents in Thuringia. Additionally, the findings point out prevention potentials such as the vaccination against HPV.

    Introduction Electronic devices in the bedroom are broadly linked with poor sleep in adolescents. This study investigated whether there is a dose-response relationship between use of electronic devices (computers, cellphones, televisions and radios) in bed prior to sleep and adolescent sleep patterns. Methods Adolescents aged 11–17 yrs (n = 1,184; 67.6% female) completed an Australia-wide internet survey that examined sleep patterns, sleepiness, sleep disorders, the presence of electronic devices in the bedroom and frequency of use in bed at night. Results Over 70% of adolescents reported 2 or more electronic devices in their bedroom at night. Use of devices in bed a few nights per week or more was 46.8% cellphone, 38.5% computer, 23.2% TV, and 15.8% radio. Device use had dose-dependent associations with later sleep onset on weekdays (highest-dose computer adjOR  = 3.75: 99% CI  = 2.17–6.46; cellphone 2.29: 1.22–4.30) and weekends (computer 3.68: 2.14–6.32; cellphone 3.24: 1.70–6.19; TV 2.32: 1.30–4.14), and later waking on weekdays (computer 2.08: 1.25–3.44; TV 2.31: 1.33–4.02) and weekends (computer 1.99: 1.21–3.26; cellphone 2.33: 1.33–4.08; TV 2.04: 1.18–3.55). Only ‘almost every night’ computer use (: 2.43: 1.45–4.08) was associated with short weekday sleep duration, and only ‘almost every night’ cellphone use (2.23: 1.26–3.94) was associated with wake lag (waking later on weekends). Conclusions Use of computers, cell-phones and televisions at higher doses was associated with delayed sleep/wake schedules and wake lag, potentially impairing health and educational outcomes.

    A retrospective review was performed of 11 children and adolescents (less than 19 years of age) with diagnosed pituitary adenomas. The patients were treated with subtotal resection and postoperative irradiation (S + R) or with irradiation alone (RT) at the Radiation Oncology Center, Mallinckrodt Institute of Radiology, Washington University Medical Center, from January 1958 through December 1982. Patient conditions at diagnosis were acromegaly in one, Nelson's syndrome in one, prolactinoma in three, chromophobe adenoma in three, and Cushing's disease in three. Median follow-up was 15.6 years (range 6.3-29.5 years). Only two patients have had failure: one at 8.6 years and the other at 20.7 years following treatment. All four patients with visual field (VF) defects at diagnosis underwent S + R, with only one developing recurrent disease. The remaining seven patients, who did not have VF defects, received RT only, and there has been one failure in this group. None have suffered long-term visual complications. All have been able to continue school and/or work. Three of eight females have borne children. Hypopituitarism requiring medication occurred in all who received S + R and in four of seven who received RT only.

    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.

    Background Voluntary medical male circumcision (VMMC) is a critical HIV prevention tool. Since 2007, sub-Saharan African countries with the highest prevalence of HIV have been mobilizing resources to make VMMC available. While implementers initially targeted adult men, demand has been highest for boys under age 18. It is important to understand how male adolescents can best be served by quality VMMC services. Methods and Findings A systematic literature review was performed to synthesize the evidence on best practices in adolescent health service delivery specific to males in sub-Saharan Africa. PubMed, Scopus, and JSTOR databases were searched for literature published between January 1990 and March 2014. The review revealed a general absence of health services addressing the specific needs of male adolescents, resulting in knowledge gaps that could diminish the benefits of VMMC programming for this population. Articles focused specifically on VMMC contained little information on the adolescent subgroup. The review revealed barriers to and gaps in sexual and reproductive health and VMMC service provision to adolescents, including structural factors, imposed feelings of shame, endorsement of traditional gender roles, negative interactions with providers, violations of privacy, fear of pain associated with the VMMC procedure, and a desire for elements of traditional non-medical circumcision methods to be integrated into medical procedures. Factors linked to effective adolescent-focused services included the engagement of parents and the community, an adolescent-friendly service environment, and VMMC counseling messages sufficiently understood by young males. Conclusions VMMC presents an opportune time for early involvement of male adolescents in HIV prevention and sexual and reproductive health programming. However, more research is needed to determine how to align VMMC services with the unique needs of this population. PMID:26938639

    An antismoking campaign aimed at the 9-18 year old Genoese school population in 1981-1985 is described. The high percentage of smokers in Italy and the worryingly early age at which the habit is acquired suggested the need for a carefully prepared ongoing programme of primary prevention that would not be limited to occasional speeches. Part of the programme was also directed towards school health officers, teachers and families for whom seminars and refresher courses and topics appropriate for each group were organised. The dangers of smoking framed in a broader context were described and debater before a total of 26,000 school children in 4 years. The results that can only now be examined due to initial difficulties in implementing the programme show that out of 4613 smokers involved in the programme 29.8% stopped smoking after a year. Significantly in the same group and in the same period only 2.5% of the school children began to smoke. In contrast 15.8% new smokers were found in the control group. Further checks on a wider sample are scheduled in order to verify and confirm the results presented.

    Background The purpose of this study was to provide additional data on the experience with frameless copper and levonorgestrel (LNG) intrauterine devices (IUDs) in nulliparous and adolescent women. Methods Nulliparous and adolescent women, 25 years of age or younger, using the frameless copper IUD or the frameless LNG-releasing intrauterine system (IUS), were selected from previous studies and a current multicenter post-marketing study with the frameless copper IUD. The small copper-releasing GyneFix® 200 IUD consists of four copper cylinders, each 5 mm long and only 2.2 mm wide. The frameless FibroPlant® LNG-IUS consists of a fibrous delivery system releasing the hormone levonorgestrel (LNG-IUS). The main features of these intrauterine contraceptives are that they are frameless, flexible, and anchored to the fundus of the uterus. Results One hundred and fifty-four nulliparous and adolescent women participated in the combined study. One pregnancy occurred with the GyneFix 200 IUD after unnoticed early expulsion of the device (cumulative pregnancy rate 1.1 at one year). Two further expulsions were reported, one with the GyneFix 200 IUD and the other with the FibroPlant LNG-IUS. The cumulative expulsion rate at one year was 1.1 with the copper IUD and 2.2 with the LNG-IUS. The total discontinuation rate at one year was low (3.3 and 4.3 with the copper IUD and LNG-IUS, respectively) and resulted in a high rate of continuation of use at one year (96.7 with the copper IUD and 95.7 with the LNG-IUS, respectively). Continuation rates for both frameless copper IUD and frameless LNG-IUS remained high at 3 years (>90%). There were no cases of perforations or pelvic inflammatory disease reported during or following insertion. Conclusion This report confirms earlier studies with frameless devices and suggests that the high user continuation rate is attributable to the optimal relationship between the IUD and the uterine cavity. IUD studies have shown that an IUD that does

    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.

    Both sleep problems and depression are common problems in adolescence, but well-defined large epidemiological studies on the relationship are missing in this age group. The aim of this study was to examine the association between depression and several sleep parameters, including insomnia, in a population-based study of adolescents aged 16-18 years, and to explore potential gender differences. A large population-based study in Hordaland County in Norway conducted in 2012, the ung@hordaland study, surveyed 10,220 adolescents aged 16-18 years (54% girls) about sleep and depression. The sleep assessment included measures of the basic sleep parameters for weekdays and weekends. Depression was defined as scoring above the 90th percentile on the total score of Short Moods and Feelings Questionnaire (SMFQ). There was a large overlap between insomnia and depression in both genders and across depressive symptoms. Depressed adolescents exhibited significantly shorter sleep duration and time in bed as well as significantly longer sleep onset latency (SOL) and wake after sleep onset (WASO). Adolescents with insomnia had a 4- to 5-fold increased odds of depression compared to good sleepers. There was also a significant interaction between insomnia, sleep duration and depression, with a more than eightfold increase in odds of depression for those who met criteria for insomnia and who slept <6 h. These associations held for both genders, but were stronger in boys. To the best of our knowledge, this is the first population-based study to investigate sleep and insomnia in relation to depression among adolescents. The findings call for increased awareness of sleep problems and depression as a major public health issue.

    Background: Tobacco use is an alarming public health problem worldwide and causes significant morbidity and mortality. In many developing countries tobacco use starts at a relative younger age. However, data on tobacco use among adolescents in Bangladesh is scarce. Objectives: The main objective of this study was to estimate the prevalence of tobacco use and its contributing factors among adolescents in Bangladesh. Materials and Methods: We used data from the Global Youth Tobacco Survey (GYTS) Bangladesh 2007 which was a school-based survey of 2,135 students aged 13-15 years in grades 7-10. Analysis: A two-stage cluster sample design was used to produce representative data for Bangladesh. At the first stage, schools were selected with probability proportional to enrollment size. At the second stage, classes were randomly selected and all students in selected classes were eligible to participate. The GYTS sample design produced representative, independent, cross-sectional estimates for Bangladesh. Results: The overall prevalence of ever cigarette smokers in Bangladeshi students was about 9%, which was more than 3 times higher in boys compared to girls (15.8% versus 4.8%). Almost 4 in 10 students start smoking before the age of 10 in Bangladesh. In addition to current cigarette smoking, another 6% also reported to use other tobacco products currently. Nine in 10 current smokers reported that they had ever received help to stop smoking. More than 4 in 10 students were exposed to smoke from other people in public places. Among current smokers, 38.3% reported that they usually buy tobacco in a store and of which 97.8% reported that they were not refused cigarette purchase because of their age. Conclusion: Implementation and enforcement of tobacco control act is an urgent public health priority in Bangladesh. PMID:28032084

    AIM: We aimed to study the relationships between circulating 25-hydroxyvitamin D [25(OH)D], insulin resistance and leptin-to-adiponectin (L/A) ratio in Guadeloupean children and adolescents and to analyse the changes in 25(OH)D levels after a 1-year lifestyle intervention program. METHODS: 25(OH)D concentrations were measured via a chemiluminescence assay. Cardiometabolic risk factors, homoeostasis model assessment of insulin resistance (HOMA-IR), and adipokines were measured. The lifestyle intervention included dietary counselling, regular physical activity. RESULTS: Among 117 girls and boys (11–15 years old, 31.6% obese), 40% had vitamin D deficiency (25(OH)D levels < 20 ng/mL). With linear regression models where 25(OH)D and HOMA-IR acted as independent variables and age, sex, BMI, L/A ratio as covariates, 25(OH)D was significantly associated with HOMA-IR alone (P = 0.036). HOMA-IR was also associated with BMI z-score ≥ 2, L/A ratio and an interaction term BMI z-score ≥ 2*L/A ratio (P < 0.001 for all). After one year, in 78 children/adolescent, mean serum 25(OH)D increased significantly from 21.4 ± 4.9 ng/mL at baseline to 23.2 ± 6.0 after 1 year; P = 0.003 whereas BMI z-score, HOMA-IR and L/A ratio decreased significantly (P = 0.003, P < 0.001 and P = 0.012; respectively). CONCLUSION: The association between 25(OH)D and HOMA-IR, independently of obesity and the high prevalence of vitamin D deficiency should be considered in order to prevent the later incidence of T2DM. A healthy lifestyle including non-sedentary and outdoor activities could be a way for improving vitamin D status. PMID:28028397

    Purpose: The 'Registry for the Evaluation of Side Effects After Radiotherapy in Childhood and Adolescence' (RiSK) has been established to prospectively characterize dose-volume effects of radiation in terms of side effects. The aim of this analysis was to characterize the function of the thyroid gland after radiotherapy to the head-and-neck region in children and adolescents. Methods and Materials: Detailed information regarding radiation doses to at-risk organs has been collected across Germany since 2001. Thyroid function was evaluated by blood value examinations of thyroid-stimulating hormone, triiodothyronine, and thyroxine. Information regarding thyroid hormone substitution was requested from the treating physicians. Results: Until May 2009, 1,086 patients from 62 centers were recruited, including 404 patients (median age, 10.9 years) who had received radiotherapy to the thyroid gland and/or hypophysis. Follow-up information was available for 264 patients (60.9%; median follow-up, 40 months), with 60 patients (22.7%) showing pathologic values. In comparison to patients treated with prophylactic cranial irradiation (median dose, 12 Gy), patients with radiation doses of 15 to 25 Gy to the thyroid gland had a hazard ratio of 3.072 (p = 0.002) for the development of pathologic thyroid blood values. Patients with greater than 25 Gy to the thyroid gland and patients who underwent craniospinal irradiation had hazard ratios of 3.768 (p = 0.009) and 5.674 (p < 0.001), respectively. The cumulative incidence of thyroid hormone substitution therapy did not differ between defined subgroups. Conclusions: Radiation-induced thyroid function impairment, including damage to the thyroid gland and/or hypophysis, can frequently be observed after radiotherapy in children. A structured follow-up examination is advised.

    Objective There are few published studies which have documented psychopathological abnormalities in patients with of adolescent idiopathic scoliosis (AIS) The aim of this study was to evaluate the psychopathological influence of AIS in Korean 19-year-old males. Methods The authors compared the Korean military multiphasic personal inventory (KMPI) military profiles of 105 AIS cases (more than 10 degrees of Cobb's angle without surgical treatment) with the KMPI profiles of 108 normal controls. The AIS group was split depending on Cobb's angle to further evaluate this relation by the severity of AIS. Results A significantly decreased result on the faking-good response scale and an significantly increased result on the faking-bad response were observed in the AIS group compared to the control (p<0.012). The neurosis scale results, including anxiety, depression and somatization symptoms, were significantly increased in the AIS group compared to the control (p<0.010). The severity level of personality disorder and schizophrenia were also significantly increased in the AIS group (p<0.010). Differences in KMPI scale scores were not related to the severity of AIS. Conclusion Young males with AIS tend to have abnormal results on the multiphasic personal inventory test compared to normal volunteers, suggesting that AIS may be related to psychopathology in the young male group in Korea. Although these psychopathology in AIS were differently observed compared to normal controls, but not interfered with military life. Clinicians are recommended to pay attention the psychopathological traits of patients with AIS. PMID:23440382

    OBJECTIVE To investigate how often family physicians see adolescents with mental health problems and how they manage these problems. DESIGN Mailed survey completed anonymously. SETTING Province of Quebec. PARTICIPANTS All 358 French-speaking family physicians who practise primarily in local community health centres (CLSCs), including physicians working in CLSC youth clinics, and 749 French-speaking practitioners randomly selected from private practice. MAIN OUTCOME MEASURES Frequency with which physicians saw adolescents with mental health problems, such as depression, suicidal thoughts, behavioural disorders, substance abuse, attempted suicide, or suicide, during the last year or since they started practice. RESULTS Response rate was 70%. Most physicians reported having seen adolescents with mental health problems during the last year. About 10% of practitioners not working in youth clinics reported seeing adolescents with these disorders at least weekly. Anxiety was the most frequently seen problem. A greater proportion of physicians working in youth clinics reported often seeing adolescents for all the mental health problems examined in this study. Between 8% and 33% of general practitioners not working in youth clinics said they had not seen any adolescents with depression, behavioural disorders, or substance abuse. More than 80% of physicians had seen adolescents who had attempted suicide, and close to 30% had had adolescent patients who committed suicide. CONCLUSION Family physicians play a role in adolescent mental health care. The prevalence of mental health problems seems higher among adolescents who attend youth clinics. Given the high prevalence of these problems during adolescence, we suggest on the basis of our results that screening for these disorders in primary care could be improved. PMID:17279202

    Improving economic resources of impoverished youth may alter intentions to engage in sexual risk behaviors by motivating positive future planning to avoid HIV risk and by altering economic contexts contributing to HIV risk. Yet, few studies have examined the effect of economic-strengthening on economic and sexual behaviors of orphaned youth, despite high poverty and high HIV infection in this population. Hierarchal longitudinal regressions were used to examine the effect of a savings-led economic empowerment intervention, the Suubi-Maka Project, on changes in orphaned adolescents' cash savings and attitudes toward savings and HIV-preventive practices over time. We randomized 346 Ugandan adolescents, aged 10-17 years, to either the control group receiving usual orphan care plus mentoring (n = 167) or the intervention group receiving usual orphan care plus mentoring, financial education, and matched savings accounts (n = 179). Assessments were conducted at baseline, 12, and 24 months. Results indicated that intervention adolescents significantly increased their cash savings over time (b = $US12.32, ±1.12, p < .001) compared to adolescents in the control group. At 24 months post-baseline, 92% of intervention adolescents had accumulated savings compared to 43% in the control group (p < .001). The largest changes in savings goals were the proportion of intervention adolescents valuing saving for money to buy a home (ΔT1-T0 = +14.9, p < .001), pursue vocational training (ΔT1-T0 = +8.8, p < .01), and start a business (T1-T0 = +6.7, p < .01). Intervention adolescents also had a significant relative increase over time in HIV-preventive attitudinal scores (b = +0.19, ±0.09, p < .05), most commonly toward perceived risk of HIV (95.8%, n = 159), sexual abstinence or postponement (91.6%, n = 152), and consistent condom use (93.4%, n = 144). In addition, intervention adolescents had 2.017 significantly greater

    Three questionnaires that measure parenting style, adolescent-family connectedness, and mental health were administered to 351 Egyptian adolescents. Results show that in rural communities the authoritarian style is more predominant in the parenting of male adolescents, while the authoritative style is more predominant in the parenting of female adolescents. In urban communities, on the other hand, the authoritarian style was more predominant in the parenting of female adolescents. The connectedness of all female adolescents with their family was stronger than that of male adolescents. The connectedness of girls was found to be more emotional and financial in villages and to be more functional in town. Female adolescents reported a higher frequency of psychological disorders. Mental health was associated with authoritative parenting, but not with authoritarian parenting. It seems that authoritarian parenting within an authoritarian culture is not as harmful as within a liberal culture.

    Social anxiety and stress type can influence strong conformity among adolescents; however, the interaction between them is not clear. In this study, 152 adolescents were recruited and assigned one of two conditions: an interaction and a judgment condition. In the interaction condition, adolescents with high social anxiety (HSA) were less likely to conform when completing a modified Asch task, compared to adolescents who had low social anxiety. In the judgment condition, adolescents with HSA were more likely to conform to the opinions from the unanimous majority. The results suggest that adolescents with HSA may show different styles of strong conformity with the change of stress type. We believe that socially anxious adolescents avoid potential social situations with weaker conformity, while avoiding negative evaluations from others with stronger conformity. These findings contribute to a better understanding of the social dysfunctions among adolescents with HSA and provide a new direction for clinical interventions. PMID:27242649

SHAZ! was originally envisioned as a larger effectiveness trial, however, the intervention was scaled back due to contextual and economic conditions in the country at the time. SHAZ! enrolled 315 participants randomly assigned to study arm within blocks of 50 participants (158 intervention and 157 control). The intervention arm participants showed statistically significant differences from the control arm participants for several outcomes during the two years of follow up including; reduced food insecurity [IOR = 0.83 vs. COR = 0.68, p-0.02], and having their own income [IOR = 2.05 vs. COR = 1.67, p = 0.02]. Additionally, within the Intervention arm there was a lower risk of transactional sex [IOR = 0.64, 95% CI (0.50, 0.83)], and a higher likelihood of using a condom with their current partner [IOR = 1.79, 95% CI (1.23, 2.62)] over time compared to baseline. There was also evidence of fewer unintended pregnancies among intervention participants [HR = 0.61, 95% CI (0.37, 1.01)], although this relationship achieved only marginal statistical significance. Several important challenges in this study included the coordination with vocational training programs, the political and economic instability of the area at the time of the study, and the difficulty in creating a true standard of care control arm. Overall the results of the SHAZ! study suggest important potential for HIV prevention intervention packages that include vocational training and micro-grants, and lessons for further economic livelihoods interventions with adolescent females. Further work is needed to refine the intervention model, and

    We present results of treatment in 36 cases of distal tibial epiphyseolysis in 34 patients treated between 1999 and 2005 with a minimal follow up of 12 months (average 28,5, range 13-84 months). The mean age at injury was 12 years (range from 7 to 16). There were 22 cases of type II injury according to the Salter-Harris classification, 5 cases of type VII, 3 of type IV, 2 of type I and two cases of triplane fracture, one case of retrospectively recognised type V and one of type III. 12 children required open reduction and K-wire fixation, the rest of 22 children underwent closed reduction followed by percutaneus fixation in 12 cases. Concomitant fibular fracture occured in 30 cases and required open reduction and fixation in 4. There were 18 good, 14 fair and 3 bad results according to Gleizes. The mean AOFAS scale result was 92.7. One child underwent 2 weeks of intravenous antybiotic therapy to recover from superficial skin infection around percutaneus K-wires. Four cases of physeal bar formation were noted. In two of them distal tibial osteotomy to correct ankle varus was necessary and one underwent bony bridge removal followed by fatty tissue interposition. The remaining physeal bar resulted in 10 degree of ankle valgus without functional dispairement.

    On the basis of data from KiGGS Wave 1, the following manuscript investigates potential differences in the health status of children and adolescents aged 3-17 years according to the family form they live in: nuclear, single-parent, or stepfamily (n = 10,298). Additionally, we investigate whether differences persist after controlling for age, gender, living area, parental social status, and getting along in the family. Parent-rated health, chronic diseases, emotional or behavior problems, health-related quality of life, and daily consumption of fruits and vegetables were analyzed (prevalence, odds ratios). While the parent-rated health was independent of the family form, the prevalence of the other outcomes differed significantly according to the family form. Emotional or behavior problems were measured more often among children and adolescents growing up in single-parent families (OR 1.62; 95% CI 1.17-2.26) or stepfamily households (OR 2.36; 95% CI 1.63-3.41) than among those growing up in nuclear families, after adjusting for age, gender, living area, social status, and getting along in the family. Additionally, children and adolescents from single-parent families had chronic diseases (OR 1.53; 95% CI 1.20-1.96) more often than their counterparts who lived together with both parents. Compared with those growing up in nuclear families, children and adolescents from stepfamilies showed a greater risk of lower health-related quality of life (OR 2.91; 95% CI 1.76-4.80) and of lower daily consumption of fruits and vegetables (OR 1.30; 95% CI 1.01-1.67). The results indicate the importance of the family context for the health of children and adolescents.

    In rhesus macaques, previous studies have shown that episodic exposure to allergen alone or combined with ozone inhalation during the first 6 months of life results in a condition with many of the hallmarks of asthma. This exposure regimen results in altered development of the distal airways and parenchyma (Avdalovic et al., 2012). We hypothesized that the observed alterations in the lung parenchyma would be permanent following a long-term recovery in filtered air (FA) housing. Forty-eight infant rhesus macaques (30 days old) sensitized to house dust mite (HDM) were treated with two week cycles of FA, house dust mite allergen (HDMA), ozone (O3) or HDMA/ozone (HDMA+O3) for five months. At the end of the five months, six animals from each group were necropsied. The other six animals in each group were allowed to recover in FA for 30 more months at which time they were necropsied. Design-based stereology was used to estimate volumes of lung components, number of alveoli, size of alveoli, distribution of alveolar volumes, interalveolar capillary density. After 30 months of recovery, monkeys exposed to HDMA, in either group, had significantly more alveoli than filtered air. These alveoli also had higher capillary densities as compared with FA controls. These results indicate that early life exposure to HDMA alone or HDMA+O3 alters the development process in the lung alveoli.

    Because loneliness is a subjective experience, it is often examined using self-reports. Yet, researchers have started to use other-reports to examine loneliness. As previous research suggests that discrepancies between self- and other views might have important implications for adolescents' mental health, the current study examines discrepancies in multi-informant reports on adolescents' loneliness in relation with prosocial behavior, aggression, and adolescents' parent-related loneliness. The sample consisted of 374 mother-adolescent dyads and 318 father-adolescent dyads (41.80% male, M age  = 15.67 years, SD = 1.25). Results indicated that informants used different reference points to assess adolescents' peer-related loneliness, but were otherwise comparable. Moreover, informant discrepancies were associated with greater adolescents' reported parent-related loneliness. The current study did not provide evidence that discrepancies were related to prosocial or aggressive behavior. The current study adds to the notion that other-reports on loneliness show substantial convergence with self-reports. In addition, this study indicates that the discrepancy between other- and self-reports on loneliness holds valuable information for adolescent socio-emotional adjustment.

At the end of the five months, six animals from each group were necropsied. The other six animals in each group were allowed to recover in FA for 30 more months at which time they were necropsied.

These alveoli also had higher capillary densities as compared with FA controls. These results indicate that early life exposure to HDMA alone or HDMA + O{sub 3} alters the development process in the lung alveoli. - Highlights: • Abnormal lung development after postnatal exposure to ozone and allergen • This remodeling is shown as smaller, more numerous alveoli and narrower airways. • Allergen appears to have more of an effect than ozone during recovery. • These animals also have continued airway hyperresponsiveness (Moore et al. 2014)

    Excessive computer and video game playing among children is being critically discussed from a pedagogic and public health point of view. To date, no reliable data for this phenomenon in Germany exists. In the present study, the excessive usage of computer and video games is seen as a rewarding behavior which can, due to learning mechanisms, become a prominent and inadequate strategy for children to cope with negative emotions like frustration, uneasiness and fears. In the survey, 323 children ranging in age from 11 to 14 years were asked about their video game playing behavior. Criteria for excessive computer and video game playing were developed in accordance with the criteria for dependency and pathological gambling (DSM-IV, ICD-10). Data show that 9.3% (N = 30) of the children fulfill all criteria for excessive computer and video game playing. Furthermore, these children differ from their class mates with respect to watching television, communication patterns, the ability to concentrate in school lectures and the preferred strategies coping with negative emotions. In accordance with findings in studies about substance-related addiction, data suggest that excessive computer and video game players use their excessive rewarding behavior specifically as an inadequate stress coping strategy.

    Research with minors, especially for preventive purposes, e.g., suicide prevention, investigating risk or self-destructive behaviors such as deviance, drug abuse, or suicidal behavior, is ethically sensitive. We present a Delphi study exploring the ethical implications of the needs formulated by researchers in an international pre-conference who would benefit from ethics support and guidance in conducting Mental Health Research with minors. The resulting List of Ethical Issues (LEI) was submitted to a 2-rounds Delphi process via the Internet, including 34 multidisciplinary experts. In the first round, the experts reviewed the LEI and completed a questionnaire. Results from this round were analyzed and grouped in nine categories comprising 40 items. In the second round, the experts had to agree/disagree with the needs expressed in the LEI leading to a final list of 25 ethical issues considered relevant for Mental Health Research with minors such as: confidentiality of the sensitive data, competence for consenting alone and risk of harm and stigma related to the methodology used in research. It was shown that studies like SEYLE (Saving and Empowering Young Lives in Europe) trigger among researchers wishes to obtain specific recommendations helping to comply with standards for good practice in conducting research with minors.

    Background Population-based self-reported data on off-label medicine use independent from health care provisions are lacking. The purpose of this study is to investigate off-label medicine use in children and adolescents in Germany in a non-clinical setting and to identify prevalence, determinants and spectrum of off-label medicine use. Methods Data were obtained from the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) conducted by the Robert Koch Institute (2003–2006). 17,450 randomly selected children aged 0–17 years took part in the drug interviews. Of those, 8,899 took at least one medicine during the 7 days preceding the interview. Off-label medicine use was defined as the discrepancy between actual use and the intended use described in the summary of product characteristics. Off-label medicine use was stratified into off-label indication, off-label age, off-label over-dosing, and off-label under-dosing. Results The prevalence rate of off-label medicine use among those who used medicines amount of is 40.2%. The prevalence rate is significantly higher in boys (41.4%), in children aged 3 to 6 years (48.7%), without migration background (40.9%), with high social status (42.5%), living in small (42.0%) and medium sized cities (41.6%), and with a poor parents rated health status (41.7%). 12,667 preparations (attributable in respect to off-label use) were taken by 8,899 children. 30% of the medicines have been used off-label. Off-label medicine use was highest in preparations of the ATC-class “C00 Cardiovascular System”. In all origins of medicine, all age groups and all ATC-classes under-dosing was the most frequent reason for off-label medicine use. Conclusions There is a considerable level of self-reported off-label medicines use in the general paediatric population. Further investigations are needed to examine in how far off-label medicine use is based on lack of knowledge or on empiricism in paediatric

    Despite growing evidence that bipolar disorder often emerges in adolescence, there are limited data regarding treatment patterns of youth with bipolar disorder in community samples. Our objective was to present the prevalence and clinical correlates of treatment utilization for a nationally representative sample of US adolescents with bipolar disorder. Analyses are based on data from the National Comorbidity Survey-Adolescent Supplement, a face-to-face survey of 10,123 adolescents (ages 13-18) identified in household and school settings. We found that of adolescents meeting DSM-IV criteria for bipolar I or II disorder (N = 250), 49 % were treated for depression or mania, 13 % were treated for conditions other than depression or mania, and 38 % did not report receiving treatment. Treatment for depression or mania was associated with increased rates of suicide attempts, as well as greater role disability and more comorbid alcohol use relative to those who had not received treatment. Treated adolescents had triple the rate of ADHD and double the rates of behavior disorders than those without treatment. Our findings demonstrate that a substantial proportion of youth with bipolar disorder do not receive treatment, and of those who do, many receive treatment for comorbid conditions rather than for their mood-related symptoms. Treatment was more common among youth with severe manifestations and consequences of bipolar disorder and those with behavior problems. These trends highlight the need to identify barriers to treatment for adolescents with bipolar disorder and demonstrate that those in treatment are not representative of youth with bipolar disorder in the general population.

    This preliminary phase of a quantitative research had two main objectives: to identify the emotional and relational components of body image in adolescents, and to determine whether the experience of body changes is dependent upon individuals' context. Two samples of adolescents, both 13 to 17 years of age, who were healthy, middle- or upper middle-class, and randomly chosen, participated in the study. Subjects were 80 French adolescents (40 boys and 40 girls) from a center for preventive medicine, and 60 American adolescents (30 boys and 30 girls), from a suburban high school. Thorough individual interviews were conducted with these adolescents on the basis of a precise interview guide in order to determine their perceptions, attitudes, and beliefs about body image. A thematic analysis of the content of these recorded interviews revealed the differences between adolescents from the two countries. I was found that the main cultural differences were based on the belief that the real body and the ideal body coincide, and on the way physical appearance is included in the diversity of relational experiences. Gender differences were shown to be centered more on the level of control of body changes and on self-assessment modes; the signs of a failing or troubled body image may find their origin on an individual level, in the particularities of the family and parental language about the body, and on a collective level in the social representation of the body. The consequences of these symbolic representations on the adolescents' body image and attitudes toward their own health, are presented and discussed.

    Objectives To survey a diverse high school population on current prescription and over-the-counter medication misuse behaviors and attitudes. Methods We administered the MUSC Inventory of Medication Experiences (MIME), a newly developed self-report instrument, in demographically diverse high schools in Charleston, SC, to assess the feasibility of its administration and determine characteristics associated with medication misuse among high school students. Results A total of 3182 students completed the MIME (93% completion rate). Nearly one-third (31%) reported misuse of a medication more than once a month. Analysis was conducted to evaluate associations between misuse and age (<15=33%, 15=32%, 16=33%, 17=30%, 18=26%, >18=34%; p=.35), grade (9=29%, 10=32%, 11=33%, 12=30%; p=.22), race (White 34%, African-American 26%, others 30%; p<.001), gender (M=32%, F=28%; p=.01), parent/guardian level of education (college=30%; p=.12), if a participant was prescribed medication (yes=46%, no=21%; p<.001), if a family member was prescribed medication (yes=40%, no=26%; p<.001), and if a family member had ever offered their prescribed medication to the student (yes=91%, no=29%; p<.001). Conclusion Medication misuse may be more pervasive than originally thought, with a notably high level among those most familiar with medications. PMID:24772383

    The main objective of this study is to evaluate the effect of immunomodulatory agents (IMAs) (Interferon-Beta, Glatiramer Acetate) in a large cohort of multiple sclerosis (MS) patients with disease onset in childhood or adolescence, treated before 16 years of age, after a long-term follow-up. A total of 130 patients were identified, 77 were treated with Avonex, 39 with Rebif/Betaferon, 14 with Copaxone. After a mean (SD) treatment duration of 53.6 +/- 27.0, 59.9 +/- 39.5 and 74.6 +/- 35.5 months, respectively, the relapse rate decreased significantly. The final EDSS score was unchanged with respect to the initial score. Similar results were also observed in subjects who continued a long-term follow-up after they were included in an observational study in 2004, and in subjects who were treated before 12 years of age. The frequency of clinical and laboratory adverse events was similar to that observed in adult patients. To conclude, IMAs were effective and well tolerated in paediatric patients with MS.

    A mathematical process, developed in Maple environment, has been successful in decreasing the error of measurement results and in the precise calculation of the moments of corrected tracer functions. It was proved that with this process, the measured tracer results of horizontal subsurface flow constructed wetlands filled with coarse gravel (HSFCW-C) can be fitted more accurately than with the conventionally used distribution functions (Gaussian, Lognormal, Fick (Inverse Gaussian) and Gamma). This statement is true only for the planted HSFCW-Cs. The analysis of unplanted HSFCW-Cs needs more research. The result of the analysis shows that the conventional solutions (completely stirred series tank reactor (CSTR) model and convection-dispersion transport (CDT) model) cannot describe these types of transport processes with sufficient accuracy. These outcomes can help in developing better process descriptions of very difficult transport processes in HSFCW-Cs. Furthermore, a new mathematical process can be developed for the calculation of real hydraulic residence time (HRT) and dispersion coefficient values. The presented method can be generalized to other kinds of hydraulic environments.

    In this investigation the attachment representations of adolescents in residential care were examined for the first time. 72 adolescents were interviewed by using the Adult Attachment Interview (AAI). At the same time the degree of adolescent psychopathology was recorded. For this purpose the caregivers completed Achenbach's Child Behavior Checklist (CBCL), the adolescents themselves answered Achenbach's Youth Self Report (YSR). The adolescents in this sample proved to be severely burdened in psychopathological terms. They had access to only an insecure and, in many cases, an extremely insecure attachment representation. For a sub-group of adolescent mothers the early infant-mother attachment was examined using Ainsworth's Strange Situation. The findings show an intergenerational transmission of insecure attachment relationships. The implications of these results for the practice of residential care inspired by attachment theory are discussed.

    Inherited deficiency of adenosine deaminase (ADA) results in one of the autosomal recessive forms of severe combined immunodeficiency. This report discusses 2 patients with ADA deficiency from different families, in whom a possible reverse mutation had occurred. The novel mutations were identified in the ADA gene from the patients, and both their parents were revealed to be carriers. Unexpectedly, established patient T-cell lines, not B-cell lines, showed half-normal levels of ADA enzyme activity. Reevaluation of the mutations in these T-cell lines indicated that one of the inherited ADA gene mutations was reverted in both patients. At least one of the patients seemed to possess the revertant cells in vivo; however, the mutant cells might have overcome the revertant after receiving ADA enzyme replacement therapy. These findings may have significant implications regarding the prospects for stem cell gene therapy for ADA deficiency.

    Background Most US adolescents do not meet guidelines of at least 60 daily minutes of moderate- to vigorous-intensity physical activity. Additionally, sedentary behaviors among this age group are of increasing concern. This study examined the association of movement behaviors with cardiovascular fitness among US adolescents. Methods Data from the 2012 NHANES National Youth Fitness Survey were used to assess the association of movement behaviors (physical activity, sedentary time, screen time) with cardiovascular fitness among adolescent males and females. Multiple logistic regressions were used to test the independent and interactive effects of movement behaviors on cardiovascular fitness. Results Among females, physical activity was directly associated with cardiovascular fitness; no significant association was observed between sedentary behaviors and CVF. Among males, sedentary time moderated the relationship between physical activity and cardiovascular fitness, such that a significant, direct association was only observed among those with high sedentary time (OR: 5.01, 95% CI: 1.60, 15.70). Conclusions Results from this cross-sectional analysis suggest that among female US adolescents, physical activity, but not sedentary behavior, is associated with cardiovascular fitness. Among males, the interaction between physical activity and sedentary time seems to be important for cardiovascular fitness. Longitudinal studies are warranted to confirm these findings.

    Hutchinson-Gilford progeria syndrome (HGPS) is a rare premature aging disorder that is most commonly caused by a de novo point mutation in exon 11 of the LMNA gene, c.1824C>T, which results in an increased production of a truncated form of lamin A known as progerin. In this study, we used a mouse model to study the possibility of recovering from HGPS bone disease upon silencing of the HGPS mutation, and the potential benefits from treatment with resveratrol. We show that complete silencing of the transgenic expression of progerin normalized bone morphology and mineralization already after 7 weeks. The improvements included lower frequencies of rib fractures and callus formation, an increased number of osteocytes in remodeled bone, and normalized dentinogenesis. The beneficial effects from resveratrol treatment were less significant and to a large extent similar to mice treated with sucrose alone. However, the reversal of the dental phenotype of overgrown and laterally displaced lower incisors in HGPS mice could be attributed to resveratrol. Our results indicate that the HGPS bone defects were reversible upon suppressed transgenic expression and suggest that treatments targeting aberrant progerin splicing give hope to patients who are affected by HGPS.

    The aim of the current study was to compare mental health problems, resilience and family characteristics in adolescents with and without delayed sleep phase (DSP) in a population-based sample. Data were taken from the youth@hordaland-survey, a large population-based study in Hordaland County in Norway conducted in 2012. In all, 9338 adolescents aged 16-19 years (53.5% girls) provided self-reported data on a wide range of instruments assessing mental health symptoms, including depression, anxiety, obsessive-compulsive behaviours, attention deficit hyperactive disorder (ADHD) symptoms, perfectionism, resilience and sleep. Measures of socioeconomic status were also included. Three hundred and six adolescents (prevalence 3.3%) were classified as having DSP [according to the International Classification of Sleep Disorders-2 (ICSD-2)] criteria. Adolescents with DSP reported higher levels of depression, anxiety and ADHD symptoms. Adolescents with DSP also exhibited significantly lower levels of resilience. The Cohen's d effect sizes ranged from small [obsessive-compulsive disorder (OCD): d = 0.15] to moderate (inattention: d = 0.71). In the fully adjusted model, the significant predictors of DSP included inattention [odds ratio (OR): 2.11], lack of personal structure (OR: 2.07), low (OR: 1.85) and high (OR: 1.91) paternal education, parents not living together (OR: 1.81), hyperactivity/inattention (OR: 1.71) and poorer family economy (OR: 1.59). In conclusion, the high symptom load across a range of mental health measures suggests that a broad and thorough clinical approach is warranted when adolescents present with DSP.

    The question of whether physical activity is associated with positive aspects of health becomes increasingly more important in the light of the health status in today's children and adolescents and due to the changing lifestyle with respect to everyday activity. The German Health Interview and Examination Survey for Children and Adolescents (KiGGS) collected the first set of nationwide representative cross-sectional data to examine the relationship between health and physical activity. Taking sociodemographic parameters into consideration, the results suggest a positive association between self-estimated general health and several types of physical activity. The results vary with respect to gender and type of physical activity. For methodological reasons, causal conclusions can only be drawn after longitudinal data of the second wave of KiGGS are available.

    In earlier studies, children of alcoholics (COAs) reported more alcohol and drug problems and higher levels of maladaptive behaviour and psychiatric distress than non-COAs. However, increased exposure to drugs and alcohol among COAs does not fully explain this phenomenon. In our family-based study design, we were able to investigate specific risk factors for alcohol problems in adolescence. In a first step, we compared a variety of psychosocial risk factors in 90 adolescents (12-18 years of age) from families with at least one alcohol-abusing parent with those of 90 adolescents of parents without alcohol disorders. In a second step, we investigated the meaning of all included risk factors for alcohol problems of the adolescents. Our results give some support to the existence of a lower extent of emotional warmth and support by parents of children in the COA sample. Moreover, males of the COA group reported more parental rejection and higher values on measures of attention problems and anxiety/depression than controls, whereas there were no such differences between females of the COA group and their control counterparts. Additionally, logistic regression analysis revealed that only the membership in a substance-using peer group and higher age are important risk factors for alcohol problems during adolescence. Considering our results, it is of great importance (a) to identify families at risk at the earliest possible stage and (b) to develop intervention and prevention programs further for parents and children to increase social competence and protect children at risk from later alcohol abuse.

    Despite the importance of family context to adolescents' reactions following disaster, little research has examined the role of parents' functioning on adolescents' disaster-related posttraumatic stress disorder (PTSD) symptoms. Using data from 288 adolescents (ages 12 to 19 years) and 288 parents exposed to a series of severe tornadoes in a rural Midwestern community, this study tested a conceptual model of the interrelationships between individual and parental risk factors on adolescents' disaster-related PTSD symptoms using structural equation modeling. Results showed that the psychological process of experiential avoidance mediated the relationship between family disaster exposure and PTSD for both adolescents and their parents. Parents' PTSD symptoms independently predicted adolescents' PTSD symptoms. Further, parents' postdisaster functioning amplified the effects of adolescent experiential avoidance on adolescents' disaster-related PTSD symptoms. Findings highlight the importance of family context in understanding adolescents' postdisaster reactions. Clinical implications are discussed.

    This article reports results from the National Survey on Teen Relationships and Intimate Violence (STRiV) for 12- to 18-year-old youth (n = 1,804). STRiV provides the first nationally representative household survey focused on adolescent relationship abuse (ARA), covering perpetration and victimization. Among respondents (37%) reporting current- or past-year dating, 69% reported lifetime ARA victimization (63% lifetime ARA perpetration). Although psychological abuse was most common for these youth (more than 60%), the rates of sexual abuse (18%) and physical abuse victimization (18%), as well as 12% reporting perpetrating physical abuse and/or sexual abuse (12%) were substantial as well. Other than differences by age and gender, ARA rates were consistent by race/ethnicity, geographic region, urbanicity, and household characteristics, highlighting the importance of universal prevention programs. Compared with youth aged 15 to 18, those 12 to 14 years old reported lower rates of psychological and sexual ARA victimization. Similarly, we found lower ARA perpetration rates for those 12 to 14. We found no gender differences for ARA victimization but found that girls perpetrated more physical ARA than boys. Girls aged 15 to 18 reported perpetrating moderate threats/physical violence at more than twice the rate of younger girls and 3 times the rate compared with boys aged 15 to 18; girls aged 15 to 18 reported perpetrating more than 4 times the rate of serious psychological abuse than boys 15 to 18. Finally, these data document the significant positive correlation between ARA victimization and perpetration. Findings suggest that when working with youth in prevention services, interventions should not be designed for monolithic groups of "victims" or "perpetrators."

    Although prevalence and incidence of type 2 diabetes mellitus (T2DM) are reportedly increasing among adolescents, national data are lacking, particularly in regard to undiagnosed T2DM. To estimate the prevalence of diagnosed and undiagnosed T2DM among US adolescents, we analyzed a nationally representative cross-section of 11,888 adolescents aged 12-19 years who received a diabetes interview in the Continuous National Health and Nutrition Examination Survey during 1999-2010. Among them, a random subsample of 4,661 adolescents also had fasting blood samples collected. Persons who reported a previous diabetes diagnosis and were either taking no medication or taking an oral hypoglycemic agent (with or without insulin) were classified as having T2DM; persons who reported using insulin alone were classified as having type 1 diabetes. Undiagnosed diabetes was defined as a fasting plasma glucose concentration of ≥126 mg/dL and was assumed to be type 2. In the fasting subsample, 31 diabetes cases (types 1 and 2) were identified, representing a prevalence of 0.84% (weighted 95% confidence interval (CI): 0.51, 1.40) (276,638 cases; 95% CI: 134,255, 419,020). Estimates of the prevalences of type 1 and type 2 diabetes were 0.48% (95% CI: 0.23, 1.02) and 0.36% (95% CI: 0.20, 0.67), respectively, indicating that T2DM accounted for 43% of all cases. Further, undiagnosed T2DM prevalence was 0.12% (95% CI: 0.05, 0.31), representing 34% of T2DM cases (40,611 cases; 95% CI: 2,850, 78,373). T2DM accounts for approximately half of adolescent diabetes in the United States, and one-third of these cases are undiagnosed.

    Phyllodes tumor of the breast is a rare fibroepithelial lesion and particularly uncommon in adolescent girls. It is thought to arise from the periductal rather than intralobular stroma. Usually, it is seen as a well-defined mass. Phyllodes tumor showing intraductal growth is extremely rare. Here we report a girl who has a phyllodes tumor with intraductal growth.

  10. Adolescent (in)vulnerability.

    Quadrel, M J; Fischhoff, B; Davis, W

    1993-02-01

    Three groups of subjects were asked to judge the probability that they and several target others (a friend, an acquaintance, a parent, a child) would experience various risks. Subjects were middle-class adults, their teenage children, and high-risk adolescents from treatment homes. All three groups saw themselves as facing somewhat less risk than the target others. However, this perception of relative invulnerability was no more pronounced for adolescents than for adults. Indeed, the parents were viewed as less vulnerable than their teenage children by both the adults and those teens. These results are consistent with others showing small differences in the cognitive decision-making processes of adolescents and adults. Underestimating teens' competence can mean misdiagnosing the sources of their risk behaviors, denying them deserved freedoms, and failing to provide needed assistance.

    The author in his present paper reports the results of studies made in an effort to reconstructively validate a method of self-imaging during childhood and adolescence. From the investigative results obtained it is apparent that during adolescence large self-image/ideal-image differences and low self-image values correlate with neuroticism, a situation which is similar to that which is usually observed in adults. Timid and introverted juveniles differ significantly from less timid and extroverted juveniles in both the self-image level and the self-image/ideal-image difference. Aside from the fact that the self-image level has been found to be relatively independent of intelligence, there are correlations between the maternal and child's self-image. It is of interest to note that the self-image level of children whose parents got a divorce is lower than that of children coming from intact families.

    Diet quality is influenced by socio-economic and geographical factors. The present study sought to assess whether adolescents' diet quality is affected by their parents' socio-economic status and whether the relationship between these factors is similar in northern and southern Europe. Data collected in the Healthy Lifestyle in Europe by Nutrition in Adolescence (HELENA) study in eight European countries were analysed. Dietary intake data were recorded via repeated 24 h recalls (using specifically developed HELENA Dietary Intake Assessment Tool software) and converted into an adolescent-specific Diet Quality Index (DQI-AM). Socio-economic status was estimated through parental educational level (Par-Educ-Lev) and parental occupation level (Par-Occ-Lev) as reported by the adolescents in a specific questionnaire. The DQI-AM data were then analysed as a function of Par-Educ-Lev and Par-Occ-Lev in northern European countries (Austria, Belgium, France, Germany and Sweden) and southern European countries (Greece, Italy and Spain). We studied a total of 1768 adolescents (age 14.7 (SD 1.3) years; percentage of girls: 52.8%; 1135 and 633 subjects from northern and southern Europe, respectively). On average, the DQI-AM score was higher in southern Europe than in northern Europe (69.1 (SD 0.1) v. 60.4 (SD 2.8), respectively; P < 0.001; Δ = 12.6%). The DQI was positively correlated with both paternal and maternal Par-Educ-Lev. However, this association was more pronounced in northern Europe than in southern Europe (P interaction = 0.004 for the mother and 0.06 for the father). The DQI was also positively correlated with Par-Occ-Lev (all P trends < 0.01), but this correlation was independent of the geographical area (P interaction = 0.51 for the mother and 0.50 for the father). In conclusion, Par-Educ-Lev and Par-Occ-Lev are associated with diet quality in adolescents in Europe. However, this association differs between northern Europe and southern Europe.

    Although there is a considerable literature on how adolescents make decisions which lead to risky behaviors (e.g., unprotected sex, drug use) and adversely affect the health and well-being of youth, little is known about the routine behaviors youth engage in which influence their health (e.g., having permanent teeth extracted, discontinuing antibiotics prematurely, delaying or going without treatment of subacute illnesses and minor injuries) and concomitantly the factors which influence these behaviors. In an effort to begin to fill this gap, we have undertaken a study of routine health behaviors and the factors which bear on them in adolescents from a high-poverty urban neighborhood. In this article, we present the results of the pilot phase of the study in which we documented the behavior of 10 adolescents from Camden, New Jersey, the fifth poorest city in the United States, and explored with them their perceptions of the decisions they made and the factors that gave rise to them. We found that participants had an insufficient understanding of their health problems and consequences of their health actions, problems in understanding and being understood by health care professionals, and reluctance to involve parents in routine health care decisions. The implications of these findings are discussed in relation to improving the health of vulnerable youth.

    Background In the evaluation of childhood obesity interventions, few researchers undertake a rigorous feasibility stage in which the design and procedures of the evaluation process are examined. Consequently, phase III studies often demonstrate methodological weaknesses. Purpose Our aim was to conduct a feasibility trial of the evaluation of WATCH IT, a community obesity intervention for children and adolescents. We sought to determine an achievable recruitment rate; acceptability of randomisation, assessment procedures, and dropout rate; optimal outcome measures for the definitive trial; and a robust sample size calculation. Method Our goal was to recruit 70 participants over 6 months, randomise them to intervention or control group, and retain participation for 12 months. Assessments were taken prior to randomisation and after 6 and 12 months. Procedures mirrored those intended for a full-scale trial, but multiple measures of similar outcomes were included as a means to determine those most appropriate for future research. Acceptability of the research and impact of the research on the programme were ascertained through interviewing participants and staff. Results We recruited 70 participants and found that randomisation and data collection procedures were acceptable. Self-referral (via media promotion) was more effective than professional referral. Blinding of assessors was sustained to a reasonable degree, and optimal outcome measures for a full-scale trial were identified. Estimated sample size was significantly greater than sample sized reported in published trials. There was some negative impact on the existing programme as a result of the research, a lesson for designers of future trials. Limitations We successfully recruited socially disadvantaged families, but the majority of families were of White British nationality. The composition of the participants was an added valuable lesson, suggesting that recruitment strategies to obtain a more heterogeneous

    Background The Hutchinson Study of High School Smoking was the first randomized trial to show effectiveness of a smoking cessation intervention on 6-months prolonged smoking abstinence at one year post-intervention in a large population-based sample of adolescent smokers. An important question remains: Do the positive effects from teen smoking cessation interventions seen at up to 12 months post-intervention endure into young adulthood? This study examines for the first time whether such positive early effects from teen smoking cessation intervention can endure into young adulthood in the absence of additional intervention. Methods High school smokers (n = 2,151) were proactively recruited into the trial from fifty randomly selected Washington State high schools randomized to the experimental (Motivational Interviewing + Cognitive Behavioral Skills Training telephone counseling intervention) or control (no intervention) condition. These smokers were followed to 7 years post high school to ascertain rates of six-year prolonged smoking abstinence in young adulthood. All statistical tests are two-sided. Results No evidence of intervention impact at seven years post high school was observed for the main endpoint of six-year prolonged abstinence, neither among all smokers (14.2% in the experimental condition vs. 13.1% in the control condition, difference = +1.1%, 95% confidence interval (CI) = -3.4 to 5.8, p = .61), nor among the subgroups of daily smokers and less-than-daily smokers, nor among other a priori subgroups. But, observed among males was some evidence of an intervention impact on two endpoints related to progress towards quitting: reduction in number of days smoked in the past month, and increase in the length of the longest quit attempt in the past year. Conclusions There was no evidence from this trial among adolescent smokers that positive effectiveness of the proactive telephone intervention for smoking abstinence, observed previously at one year post

    Study Objectives: Insomnia in adolescence adversely affects young people's current and future functioning, as well as their mental and physical health. Thus, effective and economic treatment is invaluable. The present study evaluated a 6-session multimodal group therapy, JuSt, for adolescents suffering from insomnia including cognitive-behavioral elements and clinical hypnosis. Methods: Participants (n = 19, 68.4% female) were aged 11–16 years and suffered from insomnia. Sleep onset latency (SOL), time spent awake time after sleep onset (WASO), and sleep efficiency (SE) were measured with sleep logs before and after treatment, and at 3-, 6-, and 12-month follow-up. Results: Compared to baseline, SOL and WASO significantly decreased, while there was a significant increase in SE and the feeling of being rested after the JuSt treatment. At 12-month follow-up, all parameters were still significantly different from their baseline level. The long-term effect sizes were at least as large as the short-term effects, indicating a stable improvement. Conclusions: These results suggest that the JuSt program represents a potent intervention to sustainably reduce insomniac complaints in adolescents. Given the unselected nature of our sample, a broad indication can be assumed. To further evaluate the program's efficacy, randomized controlled trials should be conducted.

    Background Adolescent diet is hypothesized to influence breast cancer risk. We evaluated the long-term effects of an intervention to lower fat intake among adolescent girls on biomarkers that are related to breast cancer risk in adults. Methods A follow-up study was conducted of 230 girls who participated in the Dietary Intervention Study in Children (DISC), in which healthy, prepubertal 8-10 year olds were randomly assigned to usual care or to a behavioral intervention that promoted a reduced fat diet. Participants were 25-29 years old at follow-up visits. All tests of statistical significance are two-sided. Results In analyses that did not take account of diet at the time of the follow-up visit, the only statistically significant treatment group difference was higher bone mineral content (BMC) in intervention group participants compared to usual care group participants; their mean BMCs were 2,444g and 2,377g, respectively. After adjustment for current diet, the intervention group also had statistically significantly higher bone mineral density and luteal phase serum estradiol concentrations. Serum progesterone concentrations and breast density did not differ by treatment group in unadjusted or adjusted analyses. Conclusion Results do not support the hypothesis that consumption of a lower fat diet during adolescence reduces breast cancer risk via effects on subsequent serum estradiol and progesterone levels, breast density or BMD. Impact Additional research is needed to clarify the association of adolescent diet with breast cancer risk and to determine if the results reported here are specific to the DISC intervention or more broadly applicable.

    This study examined whether body perception (BP) and body satisfaction (BS) among adolescents correspond with healthy body size criteria as recommended by various world health authorities, and assessed the relationships between BP and BS and physical activity (PA) among adolescents. Participants included 6274 Israeli boys and girls from grades 7-12 who took part in the first Israeli Health and Nutrition Youth survey. Data regarding their BP and BS, body mass index (BMI) and PA were gathered. Among the overweight and obese participants, 66.4% and 40.6% of the boys, respectively, and 46.7% and 26.1% of the girls, respectively, perceived their body shape and size as satisfactory (OK). Another important finding was that overweight and obese girls were three times more active than underweight girls, and the highest per cent of active boys appeared among the overweight boys or those who perceived themselves as fat. Regression analyses revealed that BMI, gender and age accounted for 29.8% of the variance in participants' BP; BMI, gender and age accounted for 22.1% of BS variance, and PA was not related to either BP or BS. In conclusion, adolescents do not perceive their body according to healthy body size criteria recommended by various world health authorities. In addition, PA as a variable does not explain body image. Therefore, increasing body awareness seems to be a fundamental step in programs that aim to reduce obesity.

    This study examined the associations between adolescents' perceived relationships with their parents, perceived parental online behaviors, and Pathological Internet Use (PIU) among adolescents. Additional testing was carried out to determine the effect of different genders (parent and adolescent). Cross-sectional data was collected from 4,559 students aged 12 to 21 years in the cities of Beijing and Jinan, People's Republic of China. Participants responded to an anonymous questionnaire concerning their Internet use behavior, perceived parental Internet use behaviors, and perceived parent-adolescent relationship. Hierarchical linear regressions controlling for adolescents' age were conducted. Results showed different effects of parent and adolescent gender on perceived parent-adolescent relationship and parent Internet use behavior, as well as some other gender-specific associations. Perceived father-adolescent relationship was the most protective factor against adolescent PIU with perceived maternal Internet use positively predicting PIU for both male and female adolescents. However, perceived paternal Internet use behaviors positively predicted only female adolescent PIU. Results indicated a different effect pathway for fathers and mothers on boys and girls, leading to discussion of the implications for prevention and intervention.

    Objectives Computer-administered cognitive–behavioural therapy (CCBT) may be a promising treatment for adolescents with depression, particularly due to its increased availability and accessibility. The feasibility of delivering a randomised controlled trial (RCT) comparing a CCBT program (Stressbusters) with an attention control (self-help websites) for adolescent depression was evaluated. Design Single centre RCT feasibility study. Setting The trial was run within community and clinical settings in York, UK. Participants Adolescents (aged 12–18) with low mood/depression were assessed for eligibility, 91 of whom met the inclusion criteria and were consented and randomised to Stressbusters (n=45) or websites (n=46) using remote computerised single allocation. Those with comorbid physical illness were included but those with psychosis, active suicidality or postnatal depression were not. Interventions An eight-session CCBT program (Stressbusters) designed for use with adolescents with low mood/depression was compared with an attention control (accessing low mood self-help websites). Primary and secondary outcome measures Participants completed mood and quality of life measures and a service Use Questionnaire throughout completion of the trial and 4 months post intervention. Measures included the Beck Depression Inventory (BDI) (primary outcome measure), Mood and Feelings Questionnaire (MFQ), Spence Children's Anxiety Scale (SCAS), the EuroQol five dimensions questionnaire (youth) (EQ-5D-Y) and Health Utility Index Mark 2 (HUI-2). Changes in self-reported measures and completion rates were assessed by treatment group. Results From baseline to 4 months post intervention, BDI scores and MFQ scores decreased for the Stressbusters group but increased in the website group. Quality of life, as measured by the EQ-5D-Y, increased for both groups while costs at 4 months were similar to baseline. Good feasibility outcomes were found, suggesting the trial process to be

    In this study, associations between current asthma and possible determinants were studied using data of the German Health Interview and Examination Survey for Children and Adolescents ("Studie zur Gesundheit von Kindern und Jugendlichen in Deutschland," KiGGS). In this nationwide cross-sectional survey, 17,461 subjects aged 0-17 years were examined between 2003 and 2006. Data collection included a medical examination of the child, an interview of the parents, and written questionnaires. Apart from prevalence estimates, multivariate logistic regression analyses were performed. Increasing age and male sex, previous atopic diseases of the child, a positive family history of allergic diseases and low birth weight were significant risk factors of asthma, as were overweight and moldy walls in the residence. Breast feeding was not associated with a reduced risk of asthma. Low age at delivery of the mother and living in rural or provincial regions were shown to be protected. Overall, this study suggests that allergies of the parents and previous atopic disease of the child are the strongest determinants of asthma. However, environmental factors (mold on walls, living in rural and provincial towns) and lifestyle factors could also modify asthma risk.

    Background and Objectives This study aims to compare the characteristics, effectiveness and results of transcatheter closure of atrial septal defect between children, adolescents, and adults. Subjects and Methods In this study, 683 patients who underwent atrial septal defect closure in the last 10 years were divided into three groups: children (age <12), adolescents (age 12 to 16), and adults (age >16) as group 1, group 2 and group 3, respectively. Results The average defect size and incidence of complex atrial septal defect were higher in group 3 (p=0.0001 and 0.03 respectively). While the average size of the devic was higher in adults (22.6±6.4 mm vs. 18.5±4.9 mm; p=0.0001), the ratio of the device size/total septum was higher in both children and adolescents (Group 1 and 2). In the child and adolescent groups and patients with only complex atrial septal defect, the use of techniques, other than standard deployment, was similar in all three groups (p=0.86 and 0.41, respectively). The ratio of the residual shunt was similar in all three groups. Major complications were seen in 5 cases (4 cases with migration, and 1 case with dislocation) in group 3 and 1 case (migration) in group 1. Conclusion Depending on the complexity of the defect and age of the patient, transcatheter closure of atrial septal defect might have certain difficulties and complications. Patients must be evaluated in detail to avoid major complications and possible problems during the procedure. PMID:27826346

    The consequences of adolescent sexual behavior are an enormous burden both for the adolescent and society. The problem is not that teens are sexually active but rather that they have little preparation and guidance in developing responsible sexual behavior. Developmentally, adolescents reach physical maturity before they are cognitively able to appreciate the consequences of their behavior. A teenager's primary source of information regarding sexuality is his or her peer group, all of whom are experiencing and reinforcing the same behaviors. The family, the major socializer of other behaviors, is not as powerful a force in shaping responsible sexual behavior because of parental discomfort with sex education and sexual discussions. This is the result of a social milieu in which sex is frequently portrayed but rarely linked with responsible behavior or accurate, nonjudgmental information. The pediatric practitioner is in an ideal position to intervene in these dynamics. In the office, the practitioner can provide accurate sexual information to both parents and adolescents, support parental-child communication on sexual issues, and provide appropriate services or referral. In the community, the practitioner can advocate for school-based sex education as well as act as an information resource. Finally, the practitioner can advocate for the health care needs for adolescents on a national level, supporting legislation that provides adolescents with information and access to services necessary to make responsible sexual decisions.

    The method used for purchasing the corrosion behaviour the WC coatings deposited by plasma spraying, on a martensitic stainless steel substrate consists in measuring the electrochemical potential of the coating, respectively that of the substrate, immersed in a NaCl solution as corrosive agent. The mathematical processing of the obtained experimental results in Matlab allowed us to make some correlations between the electrochemical potential of the coating and the solution temperature is very well described by some curves having equations obtained by interpolation order 4.

    This study describes the incidence of fatal and nonfatal injuries occurring in 87,022 Massachusetts children and adolescents during a one-year period. A surveillance system for injuries at 23 hospitals captured 93 per cent of all discharges for ages 0-19 in the 14 communities under study. Sample data were collected on emergency room visits, hospital admissions, and deaths for all but a few causes of unintentional injuries. The overall incidence was 2,239 per 10,000. The true incidence rates are probably higher than those reported. The ratio of emergency room visits to admissions to deaths was 1,300 to 45 to 1. Injury rates varied considerably by age, sex, cause, and level of severity. Age-specific injury rates were lowest for infants and elementary school age children and highest for toddlers and adolescents. The overall ratio of male to female injury rates was 1.66 to 1. Injuries from falls, sports, and cutting and piercing instruments had a high incidence and low severity. Injuries from motor vehicles, burns, and drownings had lower incidence, but greater severity. Results provide evidence that both morbidity and mortality must be considered when determining priorities for injury prevention. Current prevention efforts must be expanded to target injuries of higher incidence and within the adolescent population. PMID:6507685

    Objectives To examine the relationship between smoking, smoking cessation, and disease characteristics/quality of life (QoL) in spondyloarthritis. Methods The Scotland Registry for Ankylosing Spondylitis collects data from clinically diagnosed patients with spondyloarthritis. Clinical data, including Bath Ankylosing Spondylitis indices of disease activity (BASDAI) and function (BASFI), was obtained from medical records. Postal questionnaires provided information on smoking status and QoL (Ankylosing Spondylitis QoL questionnaire; ASQoL). Linear and logistic regression quantified the effect of smoking, and smoking cessation, on various disease-specific and QoL outcomes, adjusting for age, sex, deprivation, education and alcohol status. Results are presented as regression coefficients (β) or odds ratios (OR) with 95% confidence intervals. Results 946 participants provided data (male 73.5%, mean age 52yrs). Current smoking was reported by 22%, and 38% were ex-smokers. Ever smokers experienced poorer BASDAI (β = 0.5; 0.2 to 0.9) and BASFI (β = 0.8; 0.4 to 1.2), and reported worse QoL (ASQoL, β = 1.5; 0.7 to 2.3). Compared to current smokers, ex-smokers reported lower disease activity (BASDAI, β = -0.5; -1.0 to -0.04) and significantly better QoL (ASQoL, β = -1.2; -2.3 to -0.2). They also were more likely to have a uveitis history (OR = 2.4; 1.5 to 3.8). Conclusions Smokers with spondyloarthritis experience worse disease than never smokers. However, we provide new evidence that, among smokers, smoking cessation is associated with lower disease activity and better physical function and QoL. Clinicians should specifically promote smoking cessation as an adjunct to usual therapy in patients with spondyloarthritis. This article is protected by copyright. All rights reserved.

    Young women's experiences with sexual and reproductive health (SRH) stigma may contribute to unintended pregnancy. Thus, stigma interventions and rigorous measures to assess their impact are needed. Based on formative work, we generated a pool of 51 items on perceived stigma around different dimensions of adolescent SRH and family planning (sex, contraception, pregnancy, childbearing, abortion). We tested items in a survey study of 1,080 women ages 15 to 24 recruited from schools, health facilities, and universities in Ghana. Confirmatory factor analysis (CFA) identified the most conceptually and statistically relevant scale, and multivariable regression established construct validity via associations between stigma and contraceptive use. CFA provided strong support for our hypothesized Adolescent SRH Stigma Scale (chi-square p value < 0.001; root mean square error of approximation [RMSEA] = 0.07; standardized root mean square residual [SRMR] = 0.06). The final 20-item scale included three subscales: internalized stigma (six items), enacted stigma (seven items), and stigmatizing lay attitudes (seven items). The scale demonstrated good internal consistency (α = 0.74) and strong subscale correlations (α = 0.82 to 0.93). Higher SRH stigma scores were inversely associated with ever having used modern contraception (adjusted odds ratio [AOR] = 0.96, confidence interval [CI] = 0.94 to 0.99, p value = 0.006). A valid, reliable instrument for assessing SRH stigma and its impact on family planning, the Adolescent SRH Stigma Scale can inform and evaluate interventions to reduce/manage stigma and foster resilience among young women in Africa and beyond.

    Empirical evidence suggests that religiousness is related negatively to adolescent substance use; yet, we know little about how such protective effects might occur. The current study examined whether parents' and adolescents' religiousness are associated positively with parental, religious, and self-monitoring, which in turn are related to higher self-control, thereby related to lower adolescent substance use. Participants were 220 adolescents (45 % female) who were interviewed at ages 10-16 and again 2.4 years later. Structural equation modeling analyses suggested that higher adolescents' religiousness at Time 1 was related to lower substance use at Time 2 indirectly through religious monitoring, self-monitoring, and self-control. Higher parents' religiousness at Time 1 was associated with higher parental monitoring at Time 2, which in turn was related to lower adolescent substance use at Time 2 directly and indirectly through higher adolescent self-control. The results illustrate that adolescents with high awareness of being monitored by God are likely to show high self-control abilities and, consequently, low substance use. The findings further suggest that adolescents' religiousness as well as their religious environments (e.g., familial context) can facilitate desirable developmental outcomes.

    This study was designed to evaluate the current smoking status among adolescents of upper-secondary schools in Poland and to examine potential relationships between environmental factors (place of living and school type) and current cigarette smoking, smoking experimentation and age of first cigarette. Questionnaire survey was conducted in February - March 2005 as a project: "Health perception, life satisfaction and health behavior of upper-secondary school pupils in Poland in psychosocial and economical determinants' context". The data was collected from representative sample of pupils in Poland (N=3123), Ist and IIIrd grade students at upper-secondary schools of different school types. Almost 3/4 adolescents had reported the attempts of smoking, 1/4 declared current smoking. The smoking prevalence among boys was higher than among girls, among older pupils (18 y.) than younger (16y.) and among students living in towns. Especially there was a significant difference of rate of smoking among young women from towns than from rural areas. Special risk group of cigarette smoking were pupils of basic vocational schools. Risk of current smoking was more than 4 times higher among them, than among pupils from general secondary schools. Strategies aimed at influencing smoking behavior need to be directed especially to basic vocational schools students and girls in towns.

    Why do adolescents value their grandparents? This was the leading question of an investigation among 563 adolescents and young adults in Flanders (Belgium). The Grandparent Meaning Scale which probes eleven a priori dimensions of meaning, was completed by 147 early adolescents (M = 12.5 years), 175 middle adolescents (M = 15.7 years), and 241 late adolescents (M = 18.9 years). Results show that adolescents generally find their grandparents important and feel close to them. Grandparents are valued primarily because they provide affection, reassurance of worth, and reliable alliance. Relational-affective and caregiving meanings were assigned more often to grandmothers whereas advising, teaching, and narrative roles were ascribed more frequently to grandfathers. Maternal grandparents were generally perceived as more important and closer than paternal grandparents. Early adolescents assigned more importance and meaning to their grandparents than middle and late adolescents. There were no differences between grandsons and granddaughters.

    Adolescents' (N = 378) perceptions of and satisfaction with parenting styles, perceived parent-adolescent conflict, perceived frequency of parent-adolescent communication and related feelings, perceived parent-adolescent relationship, and mental health were assessed with rating scales and structured interviews on 2 occasions separated by 1 year. Results showed that the questionnaire and interview measures at each time could be grouped into 2 stable factors: Paternal Parenthood Qualities (PPQ) and Maternal Parenthood Qualities (MPQ). Although both factors generally had significant concurrent and longitudinal correlations with adolescents' mental health, PPQ at Time 1-predicted changes in adolescent life satisfaction, hopelessness, self-esteem, purpose in life, and general psychiatric morbidity at Time 2, whereas MPQ at Time 1 did not predict those changes. Adolescents' mental health at Time 1 was found to predict changes in MPQ but not PPQ at Time 2. Relative to maternal qualities, paternal qualities were generally found to exert a stronger impact on adolescent psychological well-being.

    High prevalence rates of depression and anxiety among adolescents underscore the importance of identifying parental and adolescent behaviors that may lessen the risk for these outcomes. Previous research has shown that parental acceptance, parental knowledge, and child disclosure are negatively associated with internalizing behaviors. It is also important to explore the impact of internalizing behaviors on these parental and child constructs. The current study examined longitudinal relationships between parental acceptance, parental knowledge, child disclosure, and internalizing symptoms across a one-year time period. Participants were 358 adolescents (54 % female) and their primary caregivers, who were primarily African American (92 %). Parents and adolescents provided data through face-to-face interviews. Results showed that parental knowledge and parental acceptance predicted child disclosure, and child disclosure predicted parental knowledge one year later. Higher levels of parental acceptance predicted lower levels of adolescent-reported depressive symptoms, while higher levels of parental report of adolescents' internalizing symptoms predicted lower levels of parental knowledge. No differences in the strength of these relationships were found across grade or gender. These findings highlight the role of the adolescent's perceived acceptance by parents in promoting children's disclosure, and the benefits of parental acceptance in decreasing depressive symptoms over time. Overall, these results show the impact that both adolescent and parental behaviors and internalizing behaviors have on each other across time.

    Last two decades witnessed great advances in the surgical treatment of idiopathic scoliosis. However, the number of studies evaluating the long-term results of these treatment methods is relatively low. During recent years, besides radiological and clinical studies, questionnaires like SRS-22 assessing subjective functional and mental status and life-quality of patients have gained importance for the evaluation of these results. In this study, surgical outcome and Turkish SRS-22 questionnaire results of 109 late-onset adolescent idiopathic scoliosis patients surgically treated with third-generation instrumentation [Texas Scottish Rite Hospital (TSRH) System] and followed for a minimum of 10 years were evaluated. The balance was analyzed clinically and radiologically by the measurement of the lateral trunk shift (LT), shift of head (SH), and shift of stable vertebra (SS). Mean age of the patients was 14.4±1.9 and mean follow-up period was 136.9±12.7 months. When all the patients were included, the preoperative mean Cobb angle of major curves in the frontal plane was 60.8°±17.5°. Major curves that were corrected by 38.7±22.1% in the bending radiograms, postoperatively achieved a correction of 64.0±15.8%. At the last follow-up visit, 10.3°±10.8° of correction loss was recorded in major curves in the frontal plane with 50.5±23.1% final correction rate. Also, the mean postoperative and final kyphosis angles and lumbar lordosis angles were 37.7°±7.4°, 37.0°±8.4°, 37.5°±8.7°, and 36.3°±8.5°, respectively. A statistically significant correction was obtained at the sagittal plane; mean postoperative changes compared to preoperative values were 7.9° and 12.9° for thoracic and lumbar regions, respectively. On the other hand, normal physiological thoracic and lumbar sagittal contours were achieved in 83.5% and 67.9% of the patients, respectively. Postoperatively, a statistically significant correction was obtained in LT, SH, and SS values (P<0

    The present study examined whether discrepancies between adolescent and parent ratings of family dynamics predict adolescent well-being over time. Self-report data from 972 adolescent-parent dyads collected at two time points separated by one year were analyzed. Both adolescents and parents rated a variety of family dynamics (e.g., cohesion), and adolescents reported on their levels of well-being (confidence, purpose in life, and positive relations with others). Significant discrepancies between adolescents' and parents' perceptions of family functioning were found for all positive family dynamics, but not for family conflict. Furthermore, discrepancies increased over time and larger discrepancies were noted for older adolescents. Results from the residualized path model showed that discrepancies were bidirectionally related to adolescent well-being. In addition, age was found to moderate the predictive model. Specifically, 14-15 year olds (year 10) were found to be more stable in their well-being over time than younger adolescents. Also, results indicate that well-being is a significantly stronger negative predictor of discrepancies over time for the 14-15 year olds (year 10) than the for 10-11 year olds (year 6). The authors suggest that future research would benefit from investigations of the relationship between divergent perspectives of family members and adjustment outcomes of adolescents.

    2006-01-01

    In a culture or society with high collectivism, contingent orientation and constrained autonomy are the prominent characteristics of adolescents' self-construal. This article examined whether Taiwanese adolescents' contingency and autonomy were associated with their prevalent preferences for buffet consumption. Findings in a panel survey indicated that contingency was positively correlated with adolescents' buffet preference, whereas autonomy was negatively correlated. Moreover, the results showed that adolescents' contingent orientation and perceived autonomy could predict their subsequent buffet preference over a half-year period. A laboratory experiment showed that adolescents who perceived lower autonomy exhibited greater preferences for buffet over the other diet consumption. In general, the results suggest that collectivist adolescents' contingency and autonomy were related to their trait-like preferences for buffet, and the state-like preferences for buffet were affected by their perceived levels of autonomy. Findings provide further insights into the impact of adolescents' self-construal on their diet consumption.

  3. Prosocial Reward Learning in Children and Adolescents

    Adolescence is a period of increased sensitivity to social contexts. To evaluate how social context sensitivity changes over development—and influences reward learning—we investigated how children and adolescents perceive and integrate rewards for oneself and others during a dynamic risky decision-making task. Children and adolescents (N = 75, 8–16 years) performed the Social Gambling Task (SGT, Kwak et al., 2014) and completed a set of questionnaires measuring other-regarding behavior. In the SGT, participants choose amongst four card decks that have different payout structures for oneself and for a charity. We examined patterns of choices, overall decision strategies, and how reward outcomes led to trial-by-trial adjustments in behavior, as estimated using a reinforcement-learning model. Performance of children and adolescents was compared to data from a previously collected sample of adults (N = 102) performing the identical task. We found that that children/adolescents were not only more sensitive to rewards directed to the charity than self but also showed greater prosocial tendencies on independent measures of other-regarding behavior. Children and adolescents also showed less use of a strategy that prioritizes rewards for self at the expense of rewards for others. These results support the conclusion that, compared to adults, children and adolescents show greater sensitivity to outcomes for others when making decisions and learning about potential rewards.

    The German Health Interview and Examination Survey for Children and Adolescents (KiGGS) 2003-2006 is the first nationwide comprehensive study on the health of children and adolescents living in Germany. The KiGGS first interview follow-up is a telephone interview study that collected, among other things, data on a number of chronic and vaccine-preventable diseases in 2009-2012 and is a combined cross-sectional and longitudinal study based on a population registry sample from the 167 KiGGS study points. The analysis is based on 12,368 respondents (7913 KiGGS follow-up participants aged 7-17 years, response 72 % and 4455 newly recruited 0- to 6-year-olds, response 42 %). Based on parent reports the lifetime prevalence of both chickenpox and pertussis has decreased in the population targeted by recently changed vaccination recommendations. For measles the prevalence remained unsatisfactorily high in each investigated age group. Of the children and adolescents aged 0-17 years 16 % (95 % confidence interval CI 15.2-17.0 %) had a long-standing chronic health condition according to the parents. Of these, however, only one in five was affected in their routine daily activities. The lifetime prevalence in 7- to 17-year-olds was 1.2 % (0.9-1.6) for epilepsy (0.4 % for the past 12 months), 5.0 % (4.4-5.7) for migraine, 0.2 % (0.1-0.3) for diabetes and in 0 to 6-year-olds 2.0 % (1.5-2.6) for heart conditions and 3.1 % (2.5-3.8) for febrile seizures with a -prevalence in 0 to 2-year-olds which are most affected of 1.0 % (0.6-1.6) in the past 12 months. The vast majority of children and adolescents in Germany are in good or very good health as suggested by other results reported in this issue; however, chronic conditions are not rare and need continuous monitoring. These results confirm that implementation of the vaccination recommendations of the German Standing Committee on Vaccination (STIKO) can lead to effective prevention of infectious diseases in Germany.

    Most autistic people present some difficulties in developing social behavior, living in their own world. The intent of this study is to improve the social life of adolescents with both autism and mental impairment, with a main focus on promoting their social interaction and communication. An experiment designed to call for the adolescents' attention and enforce their collaboration is described; in it a LEGO MindStorm robot behaves as a mediator/promotor of this interaction. Further, sensory motor coordination and accuracy skills of the adolescents are also slightly explored. Four scenarios were envisaged. Results are described showing the outcomes of the experiment.

    Background Beginning in adolescence, females are at significantly higher risk for depression than males. Despite substantial efforts, gaps remain in our understanding of this disparity. This study tested whether gender differences in adolescent-onset depression arise because of female’s greater exposure or sensitivity to violence. Methods Data came from 5692 participants in the National Comorbidity Survey Replication. Trained interviewers collected data about major depression and participants’ exposure to four types of interpersonal violence (physical abuse, sexual assault, rape, and witnessing violence) using a modified version of the Composite International Diagnostic Interview. We used discrete time survival analysis to investigate gender differences in the risk of adolescent onset depression. Results 5.7% of the sample met DSM-IV criteria for depression by age 18; 5.8% of the sample reported being physically abused, 11.7% sexually assaulted, 8.5% raped, and 13.2% witnessed violence by age 18. Females had 1.51 times higher odds of depression by age 18 than males. Exposure to all types of violence was associated with an increased odds of depression in both the past year and the years following exposure. Adjusting for exposure to violence partially attenuated the association between gender and depression, especially for sexual assault (OR attenuated=1.28; 15.23%) and rape (OR attenuated=1.32; 12.59%). There was no evidence that females were more vulnerable to the effects of violence than males. Discussion Gender differences in depression are partly explained by females’ higher likelihood of experiencing interpersonal violence. Reducing exposure to sexual assault and rape could therefore mitigate gender differences in depression. PMID:22447513

    2010-05-01

    In recent years, psychological research has emphasized the role of goals in adolescent development and, particularly, in the development of socially adapted lifestyles. Along those lines, the present study, analyzing data collected from a sample of 488 participants, explores: a) The structure of adolescent goals and their importance for young people, b) The relationship between adolescent goals and antisocial behavior and c) The role of gender in this relationship. The results show that adolescent goals are structured according to 6 factors: Social Recognition, Emancipation, Education, Physical-Athletic, Antisocial and Interpersonal-Familial. Educational and emancipative goals appear to be most important for young people. In addition, it has been found that there are significant correlations between certain types of goals and adolescent antisocial behavior, as well as significant gender differences. The data reflect the need to incorporate motivational dimensions into explanatory models of adolescent behavioral problems.

    This article describes the discrimination against adolescents orphaned by AIDS. A qualitative phenomenological approach using reflective diaries was used to extract how this population is discriminated on. Fifteen adolescents ages 14 to 18 living in an urban area in South Africa participated in the study. Data were collected as part of a larger study in which a peer-based mental health intervention was designed for use with adolescents orphaned by AIDS. Colaizzi's seven stages were used to analyze the data from the reflective diaries. Analysis revealed that adolescents orphaned by AIDS experienced physical, social, and institutional expressions of stigma leading to discrimination. Adolescents were discriminated on by peers, caregivers, and teachers. The results of this study show that adolescents orphaned by AIDS face discrimination; further studies on the topic with a larger sample are needed to verify these findings.

    Although considerable evidence shows that affective symptoms and personality traits demonstrate moderate to high relative stabilities during adolescence and early adulthood, there has been little work done to examine differential stability among these constructs or to study the manner in which the stability of these constructs is expressed. The present study used a three-year longitudinal design in an adolescent/young adult sample to examine the stability of depression symptoms, social phobia symptoms, specific phobia symptoms, neuroticism, and extraversion. When considering one-, two-, and three-year durations, anxiety and personality stabilities were generally similar and typically greater than the stability of depression. Comparison of various representations of a latent variable trait-state-occasion (TSO) model revealed that whereas the full TSO model was the best representation for depression, a trait stability model was the most parsimonious of the best-fitting models for the anxiety and personality constructs. Over three years, the percentages of variance explained by the trait component for the anxiety and personality constructs (73-84%) were significantly greater than that explained by the trait component for depression (46%). These findings indicate that symptoms of depression are more episodic in nature, whereas symptoms of anxiety are more similar to personality variables in their expression of stability.

    Objective: To analyze body image in different periods of adolescence. Methods: This cross-sectional study enrolled students aged ten to 19 years old of public schools in small districts of Minas Gerais, Southeast Brazil. The Body Shape Questionnaire (BSQ), the Body Dissatisfaction Assessment Scale for Teenagers and the Silhouette Scale for Teenagers (SST) were used. Adolescence phases were classified according to the subjects' ages. Weight and height were measured in order to calculate the body mass index and the nutritional status. Results were analyzed by logistic regression. Results: The study emolled 531 teenagers (318 females). The average age was 15.6± 2 .2 years and 84.6% were eutrophic. The prevalence of body dissatisfaction varied from 28.9% (BSQ) to 78.9% (SST). Overweight adolescents presented greater dissatisfaction (BSQ: OR 3.66, p<0.001; SST: OR 4.108, p<0.001). Dissatisfaction also occurred for females and those at the early adolescence (p<0.05). Conclusions: A low prevalence of dissatisfaction with the body image was observed among adolescents in small towns of Minas Gerais; however, most of them wished a different silhouette than the current one. The results showed that younger adolescents had higher dissatisfaction than their peers, as well as female and overweighed adolescents. PMID:24676192

    We explored young people and parents' views on adolescent drinking and safety in the locations where drinking may occur. Focus groups with adolescents and parents showed that many believed adolescent drinking and drunkenness is normative. Younger adolescents had more negative views of adolescent drinkers than their older peers. Adolescent drinking occurred in private settings and parents made decisions about allowing their adolescent children to attend social events based on the level of safety attributed to the location. If adolescent drinking was likely then home was the preferred location as it provided scope for risk minimisation. Positive portrayals of non-drinking adolescents and information to assist parents' decision-making are needed.

  1. Nonshared environmental mediation of the association between deviant peer affiliation and adolescent externalizing behaviors over time: results from a cross-lagged monozygotic twin differences design.

    It has been argued that peers are the most important agent of adolescent socialization and, more specifically, that this socialization process occurs at the child-specific (or nonshared environmental) level (J. R. Harris, 1998; R. Plomin & Asbury, 2005). The authors sought to empirically evaluate this nonshared environmental peer influence hypothesis by examining the association between externalizing behaviors and deviant peer affiliation in a sample of 454 pairs of monozygotic (genetically identical) twins, assessed at ages 14 and 17, within a cross-lagged twin differences design. Results argued against a causal nonshared environmental influence of peer affiliation on the development of externalizing behaviors and in favor of nonshared environmental "selection." In particular, the twin with more externalizing behaviors at age 14 reported increased deviant peer affiliation relative to his or her co-twin 3 years later, regardless of his or her genetic predispositions toward externalizing behavior. Such findings suggest that adolescents with higher levels of externalizing behaviors select or shape (either intentionally or inadvertently) subsequent environmental experiences to involve increased affiliation with deviant peers. Implications are discussed.

    Poverty and economic hardship remain a reality for many of America's children. Although the causes of poverty are varied, Americans strongly endorse individual responsibility as a primary cause. Because beliefs about poverty originate in childhood and adolescence, intervention efforts targeting young people may be particularly effective in shifting attitudes about the poor and policies designed to help the disadvantaged. To test this proposition, the current study evaluated the efficacy of a 1-week 8th grade social studies curriculum focusing on poverty and inequality. Study participants were upper middle-class youth enrolled in multiple sections of a Social Studies course taught by a single teacher. Participants had little direct contact with marginalized groups such as poor and homeless individuals in their communities. Students (N=66) completed a survey assessing their attitudes and beliefs about poverty and poor people prior to, and 1 week and 6 months post-instruction. Results indicated that the curriculum was partially effective in increasing the complexity of students' beliefs about poverty. Students were more likely to emphasize fatalistic causes and less likely to list individualistic causes for poverty following instruction than before, but rarely emphasized structural causes for poverty and rated individual effort as the most influential factor in determining one's success. Implications of the study findings for curriculum efforts targeting young adolescents' reasoning about economic inequality and inequity and directions for future studies are discussed.

    This study examined correlates of the discordance between sexual behavior self-reports and Incident Sexually Transmitted Infections. African American adolescent females (N = 964) from four U.S. cities were recruited for an HIV/STI prevention trial. Self-reported sexual behaviors, demographics, and hypothesized psychosocial antecedents of sexual risk behavior were collected at baseline, 6-, 12-, and 18-month follow-up assessments. Urine specimens were collected and tested for three prevalent STIs (chlamydia, gonorrhea, trichomonas) at each assessment. Seventeen percent of participants with a laboratory-confirmed STI reported either lifetime abstinence or recent abstinence from vaginal sex (discordant self-report). Lower STI knowledge, belief that fewer peers were engaging in sex, and belief that more peers will wait until marriage to have sex were associated with discordant reports. Discordance between self-reported abstinence and incident STIs was marked among African American female adolescents. Lack of STI knowledge and sexual behavior peer norms may result in underreporting of sexual behaviors.

    This work evaluates sperm head morphometric characteristics in adolescents from 12 to 18 years of age, and the effect of varicocele. Volunteers between 150 and 224 months of age (mean 191, n = 87), who had reached oigarche by 12 years old, were recruited in the area of Barranquilla, Colombia. Morphometric analysis of sperm heads was performed with principal component (PC) and discriminant analysis. Combining seminal fluid and sperm parameters provided five PCs: two related to sperm morphometry, one to sperm motility, and two to seminal fluid components. Discriminant analysis on the morphometric results of varicocele and nonvaricocele groups did not provide a useful classification matrix. Of the semen-related PCs, the most explanatory (40%) was related to sperm motility. Two PCs, including sperm head elongation and size, were sufficient to evaluate sperm morphometric characteristics. Most of the morphometric variables were correlated with age, with an increase in size and decrease in the elongation of the sperm head. For head size, the entire sperm population could be divided into two morphometric subpopulations, SP1 and SP2, which did not change during adolescence. In general, for varicocele individuals, SP1 had larger and more elongated sperm heads than SP2, which had smaller and more elongated heads than in nonvaricocele men. In summary, sperm head morphometry assessed by CASA-Morph and multivariate cluster analysis provides a better comprehension of the ejaculate structure and possibly sperm function. Morphometric analysis provides much more information than data obtained from conventional semen analysis. PMID:27751986

    Adolescents with internalizing disorders and adolescents with childhood sexual abuse related post-traumatic stress disorder (CSA-related PTSD) show a large overlap in symptomatology. In addition, brain research indicated hyper-responsiveness and sustained activation instead of habituation of amygdala activation to emotional faces in both groups. Little is known, however, about whether the same patterns of amygdala habituation are present in these two groups. The current study examined habituation patterns of amygdala activity to emotional faces (fearful, happy and neutral) in adolescents with a DSM-IV depressive and/or anxiety disorder (N=25), adolescents with CSA-related PTSD (N=19) and healthy controls (N=26). Behaviourally, the adolescents from the internalizing and CSA-related PTSD group reported more anxiety to fearful and neutral faces than adolescents from the control group and adolescents from the CSA-related PTSD group reacted slower compared to the internalizing group. At the whole brain level, there was a significant interaction between time and group within the left amygdala. Follow-up ROI analysis showed elevated initial activity in the amygdala and rapid habituation in the CSA-related PTSD group compared to the internalizing group. These findings suggest that habituation patterns of amygdala activation provide additional information on problems with emotional face processing. Furthermore, the results suggest there are differences in the underlying neurobiological mechanisms related to emotional face processing for adolescents with internalizing disorders and adolescents with CSA-related PTSD. Possibly CSA-related PTSD is characterized by a stronger primary emotional response driven by the amygdala.

    The purpose of this document is to provide an overview of the rising occurrences of adolescent violence in the American school systems and how various theories can be used to assist in understanding this phenomenon. The authors have become increasingly interested in this topic, after direct involvement in the summer of 2001. There were a number of students who were attending summer school as a result of consistent out-of-school suspensions for violent acts. The procedure to process through the system with these students was to suspend them, resulting in the student subsequently failing their present grade. The school was located in a community known for its high rate of violence and criminal activity. Various types of adolescent violence exist in our schools. Studies have reported that violent adolescents may come from familial environments that are full of social and interpersonal conflicts (Gray & Foshee, 1999). This paper discusses the development of a research plan to investigate the number and type of adolescent violent occurrences in a southern middle school setting.

    This study examined the associations between adolescents’ perceived relationships with their parents, perceived parental online behaviors, and Pathological Internet Use (PIU) among adolescents. Additional testing was carried out to determine the effect of different genders (parent and adolescent). Cross-sectional data was collected from 4,559 students aged 12 to 21 years in the cities of Beijing and Jinan, People’s Republic of China. Participants responded to an anonymous questionnaire concerning their Internet use behavior, perceived parental Internet use behaviors, and perceived parent-adolescent relationship. Hierarchical linear regressions controlling for adolescents’ age were conducted. Results showed different effects of parent and adolescent gender on perceived parent-adolescent relationship and parent Internet use behavior, as well as some other gender-specific associations. Perceived father-adolescent relationship was the most protective factor against adolescent PIU with perceived maternal Internet use positively predicting PIU for both male and female adolescents. However, perceived paternal Internet use behaviors positively predicted only female adolescent PIU. Results indicated a different effect pathway for fathers and mothers on boys and girls, leading to discussion of the implications for prevention and intervention. PMID:24098710

    Depression has a heightened prevalence in adolescence, with approximately 15 % of adolescents experiencing a major depressive episode by age 18. Depression in adolescence also poses a risk for future distress and impairment. Despite treatment advances, many adolescents relapse after initial remission. Family context may be an important factor in the developmental trajectory of adolescent depression, and thus in enhancing treatment. This study examined concurrent change over time in adolescent and maternal depressive symptoms in the context of the Treatment of Resistant Depression in Adolescents study. Participants were 334 adolescents (mean age: 16; SD: 1.6; 70 % female, 84 % Caucasian), and their mothers (n = 241). All adolescents were clinically depressed when they entered the study and had received previous selective serotonin reuptake inhibitor (SSRI) treatment. Adolescents received acute treatment for 12 weeks and additional treatment for 12 more weeks. Adolescent depression and suicidal ideation were assessed at 0, 6, 12, 24, 48 and 72 weeks, while maternal depressive symptoms were assessed at 0, 12, 24, 48 and 72 weeks. Latent basis growth curve analyses showed a significant correlation over 72 weeks between trajectories of maternal and adolescent depressive symptoms, supporting the hypothesis of concurrent patterns of change in these variables. The trajectories were correlated more strongly in a subsample that included only dyads in which mothers reported at least one depressive symptom at baseline. Results did not show a correlation between trajectories of maternal depressive symptoms and adolescent suicidal ideation. These findings suggest that adolescent and maternal depressive symptoms change in tandem, and that treatment for adolescent depression can benefit the wider family system. Notably, most mothers in this sample had subclinical depressive symptoms. Future research might explore these trajectories in dyads with more severely depressed mothers

  10. Adolescent homosexuality.

    Homosexuality has existed in all civilizations, but societal disapproval and cultural taboos have negatively influenced its recognition. A significant percentage of youths identify themselves as homosexual, and even more experience sex with the same sex or are confused about sexual feelings. A unifying etiological theory attributes the expression of sexual orientation to genes that shape the central nervous system's development, organization, and structure via prenatal sex steroids. Environmental factors may influence the expression of genetic potential. Several models of psychosocial development describe initial stages of awareness and confusion about same-sex attractions, followed by acknowledgement of homosexuality, disclosure to others, and eventual integration of sexual identity into a comprehensive sense of self. Stressors related to isolation, stigma, and violence may predispose homosexual adolescents to impaired social, emotional, and physical health, resulting in depression and suicide, school problems, substance abuse, running away eating disorders, risky sexual behavior, and illegal conduct. As with all adolescents, the overall goals in the care of homosexual youth are to promote normal adolescent development, social and emotional well-being, and physical health. A comprehensive, multidisciplinary approach is required to address medical, mental health, and psychosocial issues within the context of the adolescents' community and culture.

    To what extent do adolescents and their friends socialize each others' attitudes toward immigrants? Can friends' positive attitudes toward immigrants counter adolescents' negative attitudes toward immigrants, and do friends' negative attitudes decrease adolescents' positive attitudes? These questions were examined by following a large (N = 1,472) friendship network of adolescents (49.2 % girls; M(age) = 13.31 at first measurement) across three annual measurements. Selection and influence processes regarding tolerance and xenophobia were distinguished with longitudinal social network analyses, controlling for effects of age, gender, and immigrant background. Findings showed that friends' tolerance predicted increases in adolescents' tolerance and friends' xenophobia predicted increases in adolescents' xenophobia. Moreover, friends' tolerance predicted a lower likelihood of adolescents' xenophobia increasing. The current results suggest that interventions should distinguish between tolerance and xenophobia, as these appear to represent two separate dimensions that are each influenced in specific ways by friends' tolerance and xenophobia.

    The differences between adolescents born pre-term (n = 50) and a matched sample of adolescents born full-term were examined in relation to fear of personal death, attachment styles, and the relation between the two variables. Findings revealed that adolescents born pre-term showed a higher level of fear of personal death and a lower frequency of secure attachment style than adolescents born full-term. In addition, secure full-term born adolescents exhibited a lower level of fear of personal death compared with insecure adolescents; whereas among those born pre-term, attachment styles did not affect the level of fear of personal death. Results are discussed in terms of the long-term impact of premature birth on affect regulation in adolescence.

    This study examined the relationships between academic motivation-intrinsic motivation, extrinsic motivation, amotivation-and mathematics achievement among 363 Indian adolescents in India and 355 Indian immigrant adolescents in Canada. Results of hierarchical multiple regression analyses showed that intrinsic motivation, extrinsic motivation, and amotivation were not statistically significantly related to mathematics achievement among Indian adolescents in India. In contrast, both intrinsic motivation and extrinsic motivation were statistically significantly related to mathematics achievement among Indian immigrant adolescents in Canada. While intrinsic motivation was a statistically significant positive predictor of mathematics achievement among Indian immigrant adolescents in Canada, extrinsic motivation was a statistically significant negative predictor of mathematics achievement among Indian immigrant adolescents in Canada. Amotivation was not statistically significantly related to mathematics achievement among Indian immigrant adolescents in Canada. Implications of the findings for pedagogy and practice are discussed.

    Considering the lack of uniformity regarding school meals in Europe, information on adolescents' school lunch patterns is of public health importance. Thus, the aim of this analysis was to describe and evaluate lunchtime energy and food intake of European adolescents at different lunch locations. Data on nutritional and health-related parameters were derived from the HEalthy Lifestyle in Europe by Nutrition in Adolescence Cross-Sectional Study (HELENA-CSS). A sub-sample of 891 adolescents (47% male) with plausible data on total and lunchtime energy intake (2 × 24 h recall) as well as usual lunch location was considered. Food intake was compared to lunch of the Optimized Mixed Diet (OMD) for children and adolescents. Although energy intake was nearly in line with the recommendations, food intake was suboptimal compared to the OMD regardless of usual lunch location. Adolescents had more potatoes and less sweets at school, and more drinks (water, coffee and tea) and vegetables at home when each compared with the other locations. Food intake of adolescents getting their lunch elsewhere was characterized by the smallest amounts of potatoes and the highest amounts of sweets. Although lunch patterns may differ among countries, schools in Europe do not seem to reveal all their potential to offer access to a healthy lunch for adolescents yet.

    Previous studies have suggested that parental criticism leads to more somatic symptoms in adolescent children. However, this research has not assessed the direction of causation or whether genetic and/or environmental influences explain the association between parental criticism and adolescent somatic symptoms. As such, it is impossible to understand the mechanisms that underlie this association. The current study uses the Extended Children of Twins design to examine whether parents' genes, adolescents' genes, and/or environmental factors explain the relationship between parental criticism and adolescent somatic symptoms. Participants came from 2 twin samples, including the Twin and Offspring Study in Sweden (N = 868 pairs of adult twins and each twin's adolescent child) and from the Twin Study of Child and Adolescent Development (N = 690 pairs of twin children and their parents). Findings showed that environmental influences account for the association between parental criticism and adolescent somatic symptoms. This suggests that parents' critical behaviors exert a direct environmental effect on somatic symptoms in adolescent children. Results support the use of intervention programs focused on parental criticism to help reduce adolescents' somatic symptoms.

    The aim of the study was to investigate mental health and resilience in adolescents who have been internationally adopted and their non-adopted peers and examine the potential interaction between adoption status and resilience on mental health problems. Data from the population based youth@hordaland-survey, conducted in Hordaland County, Norway, in 2012 was used. In all, 10 257 adolescents aged 16-19 years provided self-reported data on several mental health instruments. Of these, 45 adolescents were identified as internationally adopted. Adoptees reported more symptoms of depression, attention-deficit/hyperactivity disorder (ADHD), obsessive compulsive disorder (OCD) and perfectionism than non-adopted adolescents, but there were no differences regarding resilience. Adolescents with higher resilience scores reported fewer symptoms of mental health problems, however, no interaction effects were found for adoption status and total resilience score on measures of mental health problems. Our findings indicate that knowledge of resilience factors can form the basis for preventive interventions.

  19. [Emotion Regulation and Emotional Vulnerability in Adolescents with Anxiety Disorders].

    2015-01-01

    From an attachment perspective, insecure attachment patterns in both infancy and adolescence are risk factors for the development of anxiety disorders in adolescence. Dysfunctional emotion regulation and biased social information processing are possible mediating processes. This study examines differences in emotion regulation, emotional vulnerability, and behaviour inhibition in adolescents with clinical diagnosis of anxiety disorder and healthy controls. Adolescents with anxiety disorder reported more maladaptive emotion regulation depending on the specific emotion and a higher incidence of reporting hurt feelings in social interactions. In contrast, behaviour inhibition did not explain additional variance. The results suggest that adolescents with anxiety disorders show a bias in the interpretation of social interactions as frequently emotionally hurting, and the use of dysfunctional emotion regulation strategies that minimize the possibility for effective social emotion regulation by close others or therapists. The results are interpreted within attachment framework.

    The present study examined the role of parenting styles with respect to adolescents' sleep patterns and symptoms of depression and anxiety. A total of 246 adolescents (age: 17.58+/-1.62) took part in the study. They completed several questionnaires with regard to parenting styles and to symptoms of anxiety and depression; additionally, they filled in a questionnaire assessing sleep-related personality traits and completed a sleep log for 7 consecutive days. Results showed a high overlap between parenting styles of both parents, though with a different relation to adolescents' sleep. Adverse parenting styles were highly correlated with low sleep quality, negative mood, increased daytime sleepiness, and with increased symptoms of anxiety and depression. Adolescents with low positive and high negative parenting styles displayed the most unfavorable sleep-related personality traits. Results suggest that parenting styles are related to young people's sleep pattern even at the beginning of late adolescence.

    Objective: Polycystic ovary syndrome (PCOS) is a common endocrine problem in adolescents with an increasing prevalence of 30%. Pursuing new biomarkers with high specificity and sensitivity in the diagnosis of PCOS in adolescents is currently an active area of research. We aimed to investigate the diagnostic value of anti-Müllerian hormone (AMH), insulin-like peptide-3 (INSL3), inhibin-A (INH-A), and inhibin-B (INH-B) in adolescents with PCOS and also to determine the association, if any, between these hormones and clinical/laboratory findings related with hyperandrogenism. Methods: The study group comprised 53 adolescent girls aged between 14.5 and 20 years who were admitted to our outpatient clinic with symptoms of hirsutism and/or irregular menses and diagnosed as having PCOS in accordance with the Rotterdam criteria. Twenty-six healthy peers, eumenorrheic for at least two years and body mass index-matched, constituted the controls. Fasting blood samples for hormones [luteinizing hormone (LH), follicle-stimulating hormone (FSH), dehydroepiandrosterone-sulfate (DHEAS), androstenedione (D4-A), total/free testosterone (T/fT), sex hormone binding globulin (SHBG), AMH, INSL3, INH-A, INH-B] were drawn after an overnight fast. Results: In the PCOS group, 83% of the subjects were oligomenorrheic/amenorrheic and 87% had hirsutism. The LH, LH/FSH ratio, total T, fT, free androgen-index (FAI), DHEAS levels were significantly higher (p=0.005, p=0.042, p=0.047, p<0.001, p=0.007, p=0.014, respectively) and SHBG was significantly lower (p=0.004) in PCOS patients as compared to the controls. Although the INSL-3 and INH-B levels showed no difference between the groups (p>0.05), AMH and INH-A levels were found to be significantly higher in the PCOS group compared to the controls (p<0.001, p<0.001, respectively). In multiple linear regression analysis, WC SDS (p=0.028), logD4-A (p=0.033), logSHBG (p=0.031), and total ovarian volume (p=0.045) had significant effects on AMH levels

    For asthma and psychological morbidity, it is well established that higher prevalence among males in childhood is replaced by higher prevalence among females by adolescence. This review investigates whether there is evidence for a similar emerging female 'excess' in relation to a broad range of physical morbidity measures. Establishing whether this pattern is generalised or health outcome-specific will further understandings of the aetiology of gender differences in health. Databases (Medline; Embase; CINAHL; PsycINFO; ERIC) were searched for English language studies (published 1992-2010) presenting physical morbidity prevalence data for males and females, for at least two age-bands within the age-range 4-17 years. A three-stage screening process (initial sifting; detailed inspection; extraction of full papers), was followed by study quality appraisals. Of 11 245 identified studies, 41 met the inclusion criteria. Most (n = 31) presented self-report survey data (five longitudinal, 26 cross-sectional); 10 presented routinely collected data (GP/hospital statistics). Extracted data, supplemented by additional data obtained from authors of the included studies, were used to calculate odds ratios of a female excess, or female:male incident rate ratios as appropriate. To test whether these changed with age, the values were logged and regressed on age in random effects meta-regressions. These showed strongest evidence of an emerging/increasing female excess for self-reported measures of headache, abdominal pain, tiredness, migraine and self-assessed health. Type 1 diabetes and epilepsy, based on routinely collected data, did not show a significant emerging/increasing female excess. For most physical morbidity measures reviewed, the evidence broadly points towards an emerging/increasing female excess during the transition to adolescence, although results varied by morbidity measure and study design, and suggest that this may occur at a younger age than previously thought.

    The purposes of this study were to assess the ways adolescents in active-duty military families provide emotional and instrumental support to civilian mothers and to investigate the implications of such support for their own symptoms of depression. Eighty adolescents from active-duty military families provided self-report ratings of emotional and instrumental support rendered to their civilian mothers. Mother-adolescent dyads engaged in a 10-min discussion of military experiences, which was coded for adolescents' emotional validation of their mothers. Path analyses showed that adolescents who provided more instrumental support and showed more emotional validation reported fewer symptoms of depression. However, adolescents' instrumental support to the mother was not inversely associated with their depression symptoms when the mothers reported high depression symptoms. Recent military demands did not moderate associations between adolescent support and depression symptoms. In this, the first study to our knowledge assessing youth-to-parent support provision among military adolescents, results suggest that emotional validation and instrumental support given at will by adolescents to their civilian mothers are associated with lower levels of adolescent depressive symptoms. Results also underscore the impact of maternal depression on family processes and emphasize the importance of careful assessment of support processes within military families.

    It is widely accepted that researchers have an obligation to inform survey participants of research results. However, there is little evidence on the effectiveness of various dissemination strategies. The emerging field of knowledge transfer and exchange (KTE) may offer insight given its focus on techniques to enhance the effectiveness of communicating evidence-based information. To date, KTE has focused primarily on information exchange between researchers and policy-makers as opposed to study participants; however, there are principles that may be relevant in this new context. This gap in the literature becomes even more salient in the context of public health research where research results can reveal particular misunderstandings or shortcomings in knowledge that threaten to severely compromise participants' health. The objective of this article is to describe how KTE principles were used to inform dissemination of results of a self-administered sexual health survey to adolescent study participants in a resource-deprived, peri-urban area of South Africa. Strategies for enhancing two-way information exchange included constructing interactive dissemination sessions led by young, isiZulu fieldworkers. We also employed techniques to create a safe space for dialogue, encouraged the shared ownership of results and crafted targeted messages. Particularly noteworthy was the benefit accrued by the research team through this process of exchange, including novel explanations for study findings and new ideas for future research.

    Background Emotions are potent modulators and motivators of the behaviour that the individual displays in the different situations they have to live and they can act as a protection factor or vulnerability of the adapted or maladaptive behaviour. This study focuses on anxiety in adolescence. Objectives. The objective is, through a longitudinal study, to analyse the psychological processes and emotions that facilitate the symptoms of anxiety and those which protect the adolescent from these symptoms. Material and Methods 417 adolescents (192 boys and 225 girls) participated in a three-wave longitudinal study in Valencia, Spain. In the first wave, adolescents were either in the third year of secondary school (81 boys and 85 girls) or the fourth year of secondary school (111 boys and 140 girls). The mean age was 14.70 (SD = 0.68; range = 13-17 years). This study monitored participating adolescents for three years. Results The results indicate a differential profile in the evaluated emotions according to sex, with the girls being the ones to experiment more anxiety and more empathy, while the boys show more emotional instability and aggression. Conclusions It is concluded that the best predictors for anxiety are anger state, aggressive behaviour, empathic concern together with the lack of coping mechanisms focused on problem solving and the perception of stress as a threat. Key words:Adolescence, anxiety, emotions, coping, stress. PMID:27988785

    Purpose To examine the association between depressive symptoms and subclinical markers of cardiovascular disease (CVD), specifically arterial stiffness, as indexed by pulse wave velocity (PWV), and carotid artery intima thickening (IMT), in a sample of healthy adolescents, and to explore adolescent hostility as a potential moderator of depression on subclinical markers of CVD. Methods One hundred and fifty-seven (n = 157) black and white adolescents between the ages of 16-21 completed a follow-up study of psychosocial stress and cardiovascular risk factors that included measures of PWV and carotid IMT. Psychosocial measures included the Center for Epidemiologic Studies Depression Scale (CES-D; divided into tertiles), and the Cook-Medley Hostility Inventory subscales. Linear regression models controlled for sociodemographic variables, health behaviors, blood pressure, body mass index, and heart rate. Results Results show that more severe depressive symptoms were associated with higher levels of PWV (B = 0.17, R2 = 0.30, ΔR2 = 0.03, CI = 2.2 – 47.0, p = .03) but not with higher IMT. Adolescent depression remained a significant predictor of PWV when controlling for adolescent hostility; hostility did not moderate the relationship between adolescent depression and PWV. Conclusions Depression may be important in the development of arterial stiffness in adolescence. Further research is needed to delineate the relationship in adolescence and young adulthood between depressive symptoms and the pathogenesis of CVD. PMID:21575817

    In a longitudinal study of children followed for 8 years into adolescence, the authors investigated how different forms of maltreatment (i.e., harsh parenting, sexual abuse, witnessing domestic violence) in childhood and parenting during adolescence influenced adolescents' shame- and guilt-proneness. Furthermore, the authors examined whether diminished feelings of guilt or heightened feelings of shame were related to delinquent behavior or depression in late adolescence. Results showed that whereas harsh parenting in childhood was related to shame proneness in adolescence, this relationship was mediated by parental rejection in adolescence. Findings confirmed that youth with rejecting parents were more shame-prone and less guilt-prone than other youth. Furthermore, shame-proneness was associated with higher depression when measured 2 years later and guilt-proneness was linked to less delinquent behavior. Results suggest that, as mediators, shame and guilt may provide useful focal points for intervention and prevention efforts in reducing adolescent depression and delinquency.

    Adolescent suicide is now a major health concern for many countries. However, there is paucity of systematic studies and lack of official statistics on adolescent suicide in Ghana. Mass media coverage of adolescent suicide (even though crude), at least, may reflect the reality of the phenomenon. With an ecological orientation, this study used qualitative content analysis to analyse the pattern of 44 media reports of adolescent suicide in Ghana from January 2001 through September 2014. Results showed that hanging was the dominant method used. The behaviour usually takes place within or near the adolescent's home environment. The act was often attributed to precursors within the microsystem (family and school) of the deceased. This study serves a seminal function for future empirical studies aimed at deeper examination of the phenomenon in order to inform prevention programmes. PMID:26015405

    This study examined the relations between cultural values (i.e., individualism and collectivism) and aggression among 460 (234 girls) Chinese adolescents. Conflict level and social status insecurity were examined as potential explaining mechanisms for these relations. The results showed that adolescents' endorsement of collectivism was negatively related to their use of overt and relational aggression as reported by teachers and peers, whereas positive associations were found between the endorsement of individualism and adolescent aggression. Adolescents' conflict level and social status insecurity accounted for a significant part of these associations. Findings of this study demonstrate the importance of examining intracultural variations of cultural values in relation to adolescent aggression as well as the process variables in explaining the relations.

    Affective Theory of Mind (ToM), an important aspect of ToM, involves the understanding of affective mental states. This ability is critical in the developmental phase of adolescence, which is often related with socio-emotional problems. Using a developmentally sensitive behavioral task in combination with functional magnetic resonance imaging, the present study investigated the neural development of affective ToM throughout adolescence. Eighteen adolescent (ages 12-14 years) and 18 young adult women (aged 19-25 years) were scanned while evaluating complex affective mental states depicted by actors in video clips. The ventromedial prefrontal cortex (vmPFC) showed significantly stronger activation in adolescents in comparison to adults in the affective ToM condition. Current results indicate that the vmPFC might be involved in the development of affective ToM processing in adolescence.

    2009-01-01

    Religiousness is widely considered to be a culturally transmitted trait. However, twin studies suggest that religiousness is genetically influenced in adulthood, although largely environmentally influenced in childhood/adolescence. We examined genetic and environmental influences on a self-report measure of religiousness in a sample consisting of 284 adoptive families (two adopted adolescent siblings and their rearing parents); 208 biological families (two full biological adolescent siblings and their parents); and 124 mixed families (one adopted and one biological adolescent sibling and their parents). A sibling-family model was fit to the data to estimate genetic, shared environmental, and nonshared environmental effects on religiousness, as well as cultural transmission and assortative mating effects. Religiousness showed little evidence of heritability and large environmental effects, which did not vary significantly by gender. This finding is consistent with the results of twin studies of religiousness in adolescent and preadolescent samples. PMID:20161346

    Previous research has been largely silent about what precisely influences online friendship formation and has ignored motives for online communication as potential explanations. Drawing on a sample of 493 adolescents, this study tested a path model of adolescent friendship formation including as predictors introversion/extraversion, online self-disclosure, motive for social compensation, and frequency of online communication. Our path analysis showed that extraverted adolescents self-disclosed and communicated online more frequently, which, in turn, facilitated the formation of online friendships. Introverted adolescents, by contrast, were more strongly motivated to communicate online to compensate for lacking social skills. This increased their chances of making friends online. Among introverted adolescents, a stronger motive for social compensation also led to more frequent online communication and online self-disclosure, resulting in more online friendships. The model suggests that the antecedents of online friendship formation are more complex than previously assumed and that motives for online communication should be studied more closely.

    Statistically significant changes in pulmonary functional measurements in asthmatic adolescents exposed to sulfur dioxide (SO/sub 2/) at reset and during exercise were recently reported. To determine whether those results were due to the subjects' adolescence or to their asthma, the identical exposures were repeated in healthy adolescents. The healthy subjects showed small, statistically significant changes after exposure to SO/sub 2/, but these changes were slight compared to those seen in the asthmatic adolescents. It was concluded that asthmatic adolescents are much more sensitive to the effects of inhaled SO/sub 2/ than are healthy adolescents. (JMT)

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

  18. Association of breakfast intake with obesity, dietary and physical activity behavior among urban school-aged adolescents in Delhi, India: results of a cross-sectional study

    2012-01-01

    Background In developed countries, regular breakfast consumption is inversely associated with excess weight and directly associated with better dietary and improved physical activity behaviors. Our objective was to describe the frequency of breakfast consumption among school-going adolescents in Delhi and evaluate its association with overweight and obesity as well as other dietary, physical activity, and sedentary behaviors. Methods Design: Cross-sectional study. Setting: Eight schools (Private and Government) of Delhi in the year 2006. Participants: 1814 students from 8th and 10th grades; response rate was 87.2%; 55% were 8th graders, 60% were boys and 52% attended Private schools. Main outcome measures: Body mass index, self-reported breakfast consumption, diet and physical activity related behaviors, and psychosocial factors. Data analysis: Mixed effects regression models were employed, adjusting for age, gender, grade level and school type (SES). Results Significantly more Government school (lower SES) students consumed breakfast daily as compared to Private school (higher SES) students (73.8% vs. 66.3%; p<0.01). More 8th graders consumed breakfast daily vs.10th graders (72.3% vs. 67.0%; p<0.05). A dose–response relationship was observed such that overall prevalence of overweight and obesity among adolescents who consumed breakfast daily (14.6%) was significantly lower vs. those who only sometimes (15.2%) or never (22.9%) consumed breakfast (p<0.05 for trend). This relationship was statistically significant for boys (15.4 % vs. 16.5% vs. 26.0; p<0.05 for trend) but not for girls.

    Culture and tradition influences behaviour. Multiple partner and concurrent relationships are made responsible for the increase of HIV infection in Sub-Saharan Africa. A contextualized "Theory of Planned Behaviour" was used to identify predictors of intention to practice monogamy. A mixed method design using qualitative data from focus groups, stories and a survey were analyzed for quantitative data. The qualitative data added to the behavioural beliefs a socio-cultural belief domain as well as attitudes, subjective norms, and perceived behavioural control predicted the intention to practice monogamy. The adolescents showed a tendency towards having more than one sexual partner. The normative beliefs and the socio cultural beliefs also predicted intentions while hedonistic belief and partner reaction did not. In contextualizing theory-based interventions, it is important to draw from stories and the langauage that circulate in a community about a given behaviour. More studies are needed on ways to combine qualitative approaches with quantitative approaches to inform the development of theory based culturally appropriate and context specific intervention strategies to reduce the risk of HIV.

    Objectives. To replicate an evidence-based HIV risk reduction program and assess its impact on 2 behavioral outcomes—inconsistency of condom use and frequency of sex—6 months after the program. Methods. The study was an individual-level randomized controlled trial in which we randomly assigned 850 youths (aged 14–18 years) to 1 of 2 conditions. The treatment (Becoming a Responsible Teen) is a group-level sociocognitive and skills training sexual education course; the control is a general health intervention that includes the same initial informational component as the treatment. Participants were recruited over 3 summers (2012–2014) from a summer employment program in New Orleans, Louisiana, that serves primarily African American adolescents. Results. Six months after program exposure, we found no statistically significant difference between treatment and control group members’ self-reported inconsistency of condom use or frequency of sex (P > .05). Conclusions. Although previous evidence has indicated that this particular program can be effective, this study’s findings indicate that it was not effective in this setting with this specific population. Results should provide an incentive to learn why the intervention works in some cases and what conditions are necessary for causal impacts. PMID:27689499

    Given that social influences are among the strongest predictors of adolescents' drug use, this study examined the effect of social interaction on morphine-induced hyperlocomotion in both adolescent and adult mice. Three experimental groups of adolescent and adult male mice were examined (i) morphine-treated mice (twice daily, 10-40 mg/kg, subcutaneous), (ii) saline-injected mice housed together with the morphine-treated mice ('saline cage-mates'), and (iii) saline-injected mice housed physically and visually separated from the morphine-treated mice ('saline alone'). After the treatment period, mice were tested individually for their locomotor response to 10 mg/kg morphine (subcutaneous). Adolescent saline cage-mates, though administered morphine for the very first time, exhibited an enhanced hyperlocomotion response similar to the locomotor sensitization response exhibited by the morphine-treated mice. This was not observed in adults. In adults, there were no significant differences in morphine-induced hyperlocomotion between saline alone and saline cage-mates. As expected, morphine-treated adults and adolescents both exhibited locomotor sensitization. These results show a vulnerability to social influences in adolescent mice, which does not exist in adult mice.

    The current diagnostic system suggests that personality disorder categories be applied to children and adolescents in rare circumstances due to expected changes in personality pathology across development. The present study examined the stability in personality pathology, specifically psychopathy, across childhood and adolescence. Using a short form of the Childhood Psychopathy Scale (CPS; Lynam, 1997) and mixed models incorporating fixed and random effects, we examined the reliability, individual stability, mean-level stability, and predictive utility of juvenile psychopathy as a function of age (i.e., from 7 years old to 17 years old) in over 1500 boys from the three cohorts of the Pittsburgh Youth Study. If adolescent development contributes to instability in personality pathology, large age-related fluctuations in reliability, stability, and predictive utility should be observed, particularly in the latter part of adolescence when normative changes are hypothesized to influence levels of psychopathy. Such fluctuations were not observed. In general, juvenile psychopathy could be reliably assessed beginning in childhood, was fairly stable across short and long intervals, showed little mean-level fluctuation, and predicted delinquency across adolescence. These results suggest that concerns about large changes in personality pathology across childhood and adolescence may be overstated. Implications and future directions are discussed. PMID:19825261

    This study explored the relationship between parenting styles and self-esteem among 1,239 11- to 15-yr.-old Brazilian adolescents (54% girls; M age= 13.4 yr., SD= 1.4). Teenagers' families were classified into 1 of 4 groups (Authoritative, Authoritarian, Indulgent, or Neglectful) based on adolescents' answers to the ESPA29 Parental Socialization Scale. Participants completed the AF5 Multidimensional Self-Esteem Scale which appraises five dimensions: Academic, Social, Emotional, Family, and Physical. Analyses showed that Brazilian adolescents from Indulgent families scored equal (Academic and Social) or higher (Family) in Self-esteem than adolescents from Authoritative families. Adolescents from Indulgent families scored higher than adolescents from Authoritarian and Neglectful families in four Self-esteem dimensions, Academic, Social, Family, and Physical. Adolescents from Authoritative families scored higher than adolescents from Authoritarian and Neglectful families in three Self-esteem dimensions, Academic, Social, and Family. These results suggest that Authoritative parenting is not associated with optimum self-esteem in Brazil.

    Objective: This study was undertaken to evaluate the efficacy of a skills-based CD-ROM intervention, with and without a parent component, to reduce alcohol use among urban youth at 6-year follow-up. Method: At recruitment, 513 youths with a mean age of 10.8 years were randomly assigned to one of three study arms: youth CD-ROM intervention plus parent component, youth CD-ROM intervention only, or control. All youths completed pretest, posttest, and annual follow-up measures. Youths and parents in their respective arms received the initial intervention program between pretest and posttest measures and received booster interventions between each follow-up measure. Results: With 80% sample retention at 6-year follow-up, youths in both intervention arms reported less past-month alcohol and cigarette use and fewer instances of heavy drinking and negative alcohol-related consequences. Despite having similar numbers of drinking peers as youths in the control arm, youths in both intervention arms reported greater alcohol-refusal skills. Only past-month cigarette use differed between the two intervention arms, with youths in the intervention-plus-parent-component arm smoking less than youths in the CD-ROM intervention-only arm. Conclusions: Six years after initial intervention, youths who received a culturally tailored, skills-based prevention program had reduced alcohol use and lower rates of related risky behaviors than youths in the control arm.

    Insufficient sleep may lead to adverse health effects, influencing body weight. This study quantified the prevalence of short sleep and the association between sleep duration and overweight in a sample of suburban students. Cross-sectional study was conducted in 2004, involving 529 students from Bay High School, Bay Village, OH, USA, using self-administered questionnaires assessing lifestyle and sleep behaviors. Students with a body mass index Z Score >85th percentile for sex and age were deemed overweight. Ninety percent of students reported average sleep time less than 8 h on school nights, with 19% reported less than 6 h of sleep per night. Twenty percent of the sample were overweight. Overweight was significantly associated with the male gender, increased caffeine consumption, and short sleep duration. Compared with students sleeping >8 h, the age and gender-adjusted odds ratio of overweight was 8.53 (95% CI: 2.26, 32.14) for those with <5 h sleep (P = 0.0036); 2.79 (1.03, 7.55) for those with 5-6 h sleep; 2.81 (1.14, 6.91) for those with 6-7 h sleep; and 1.29 (0.52, 3.26) for those with 7-8 h sleep. Short sleep duration was common and associated with overweight with evidence of a "dose-response" relationship. These results confirm a high prevalence of short sleep among suburban high school students and provide additional support suggesting significant association between short sleeping hours and overweight.

    This study aims at investigating the impact of parental practices on youths' adjustment. In all, 605 adolescents completed questionnaires at ages 14, 16 and 18. Self-esteem, psychological distress as well as parental emotional support and coercive control were measured. Analyses based on individual growth models revealed that self-esteem increased with age, but psychological distress remained stable over time. Boys reported higher levels of self-esteem and lower levels of psychological distress than girls. Maternal and paternal emotional support reinforced self-esteem over time. Maternal coercive control undermined self-esteem, but only at ages 16 and 18. Psychological distress decreased with parental emotional support but increased with parental coercive control at ages 14, 16 and 18. Overall, these results indicate that positive parental practices are related to youths' well-being. These findings support the importance of establishing intervention strategies designed to promote best practices among parents of teenagers to help them develop into well-adjusted adults.

    The German Environmental Survey for Children (GerES IV) is the environment-related module of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) of the Robert Koch Institute and the fourth GerES of the Federal Environment Agency. The main objective of GerESs is to analyse and document the extent, distribution and determinants of exposure to environmental pollutants of the German general population. GerES IV was performed from 2003 to 2006. A total of 1.790 children aged 3-14 years from 150 sampling locations participated in GerES IV. Samples of blood, urine, tap water, house dust and indoor air were analysed. Hearing tests, measurements of traffic noise and interviews to get exposure-related information were conducted. First results indicate a clear decrease of the exposure to arsenic, lead and mercury. Cotinine concentrations in urine can be used to classify the exposure of children to environmental tobacco smoke. The examination of the tap water used in the subjects' households indicates that in some households the guideline values of the German Drinking Water Ordinance were not always met. This is the case for nickel, copper and lead which are used as pipe material for domestic plumbing.

    Enzyme immunoassay was used to determine the presence of immunoglobulins class G to Toxocara canis antigens in the sera of children and adolescents (hereinafter referred to as children) with allergic and bronchopulmonary diseases from HIV infection and hepatitis B and C risk groups. A total of 422 dwellers of the Republic of Altai, including 144 subjects aged 1 to 17 years, were examined. Toxocara antibodies were found in 18.8 +/- 3.3% of the children and in 21.9 +/- 2.5% of the adults. The infection rate in children with bronchopulmonary and allergic diseases was 27.1 +/- 5.8 and 14.3 +/- 5.0%, respectively; that in the hepatitis B and C risk groups was 13.1 +/- 6.2%. The children (n = 6) from the HIV infection risk group were seronegative. The infection rate in the adults from the HIV infection and hepatitis risk group was 19.2 +/- 3.5 and 24.3 +/- 3.5%, respectively. Diagnostic antibody titers in the children and adults were determined in 9.0 +/- 2.3 and 8.3 +/- 1.6%, respectively. Immunological assays should be used to rule out toxocariasis in the examinees. If there are seropositive results, specific antiparasitic threatment should be performed.

    Sexually transmitted diseases (STDs) are a serious health problem for adolescents, occurring in an estimated one-quarter of sexually active teen-agers. Many of the health problems--including STDs--result from specific risk-taking behaviors. Determinants of STD risks among adolescents include behavioral, psychological, social, biological, institutional factors. Education is an important component in STD control in adolescents. The goal of education is to increase adolescent self-efficiency in practicing STD prevention and risk-reduction. A comprehensive approach including quality, theory-based education, accessible and effective health clinics, and improved social and economic conditions has the most promise of controlling STDs in adolescents.

    Few studies examine relationships between intercultural strategies and adaptation among adolescents using a person-oriented approach. Framed from an intercultural psychology perspective, this study used such an approach in order to examine the influence of intercultural profiles, patterns of relationships among variables related to intercultural strategies, on the adaptation of adolescents of both non-dominant and dominant groups. Two hundred and fifty-six adolescents living in Italy and aged from 14 to 18 participated to the study: 127 immigrants from Tunisia (males = 49.61%) and 129 autochthonous (males = 44.19%). Data were collected through self-report questionnaires. Using cluster analytic methods to identify profiles, the results showed that immigrant adolescents were divided in two acculturation profiles, ethnic and integrated-national, with adolescents belonging to the latter showing higher self-esteem, life satisfaction and sociocultural competence than the former. Also among autochthonous adolescents two acculturation expectation profiles were identified, not-multicultural and multicultural, with adolescents belonging to the latter showing higher self-esteem and life satisfaction than the former. Findings highlight the importance of using multiple indicators in order to gain a more comprehensive understanding of the acculturation process as well as suggesting implications for the social policies in this field.

    Previous literature has demonstrated the separate contributions of parental attributions and adolescent attributions to psychosocial adjustment of adolescents with chronic illness. However, it is unknown whether parental attributions affect adolescents' mental health directly or indirectly by influencing the youths' attributional style. This study evaluated the direct and indirect (through adolescent attributions) effects of parental attributions on internalizing and externalizing problems of adolescents with chronic illness. Adolescents (N = 128; M = 14.7 years) diagnosed with cystic fibrosis or diabetes and their caregivers completed measures of attributional style and adolescent adjustment. Parents' optimistic attributions were associated with fewer adolescent internalizing and externalizing problems. These effects were partly mediated by adolescent attributions. These results suggest that targeting both adolescent and parent attributions may be important for improving adolescents' adjustment to a chronic illness.

    The transition from childhood to adolescence is widely believed to be a stressful period in which the child faces multiple changes: physical changes, school choices, development of new social roles, and changes in the relation with his or her parents and friends. We investigated the effects of the timing of puberty on mental health, studied in a population of 219 young adolescents who were followed during three years (mean age at the beginning of the study was 12.5 years). The changes in the perception of the individual's body associated with puberty depended on the child's gender. Significant events during puberty had a negative effect on mental health. Although puberty remains a critical period of temporary unstable and fragile transition, most of the young adolescents coped relatively well with the physiological, psychological and social changes they faced.

    Little is known concerning obesity patterns of ethnic subpopulations in the U.S. and the effects of acculturation on these patterns. Adolescent obesity, a major public health problem, has important health, social and economic consequences for the adolescent. The National Longitudinal Study of Adolescent Health survey is unique in the size of the adolescent sample and in its ability to provide large representative samples of Anglo, African-American, Hispanic and Asian-American adolescents. A nationally representative sample of 13,783 adolescents was studied. Measurements of weight and height collected in the second wave of the survey were used to study adolescent obesity. Multivariate logit techniques were used to provide an understanding of the ethnic, age, gender and intergenerational patterns of adolescent obesity. Comparisons are presented between the NHANES III results and those from the Adolescent Health Survey. The smoothed version of the NHANES I 85th percentile cut-off was used for the measure of obesity in this paper. For the total sample, 26.5% were obese. The rates were as follows: white non-Hispanics, 24.2%; black non-Hispanics, 30.9%; all Hispanics, 30.4%; and all Asian-Americans, 20.6%. Important variations within the Hispanic and Asian-American subpopulations are presented. The Chinese (15.3%) and Filipino (18.5%) samples showed substantially lower obesity than non-Hispanic whites. All groups showed more obesity among males than among females, except for blacks (27.4% for males and 34.0% for females). Asian-American and Hispanic adolescents born in the U.S. are more than twice as likely to be obese as are first generation residents of the 50 states.

    Two mechanisms have been proposed regarding relations between parental responses to adolescent affective behaviours and the development of depression: the elicitation of parental negativity and the suppression of parental aggression. This study aimed to investigate the boundary conditions under which these two mechanisms operate in relation to the prospective prediction of Major Depressive Disorder (MDD) onset in adolescence. A community sample of 159 adolescents (aged 11-13 years) with no history of MDD completed a family interaction assessment with their mothers, and were followed-up with a diagnostic interview 2-3 years later. Results showed that onset of MDD was prospectively predicted by the elicitation of maternal aggression in response to adolescent aggression (in girls only) and maternal dysphoria in response to adolescent aggression, as well as the suppression of maternal aggression and dysphoria in response to adolescent dysphoria. Thus, support was obtained for both the elicitation of negativity mechanism in relation to maternal responses to adolescents' aggressive behaviours, and the suppression of aggression mechanisms in relation to maternal responses to adolescents' dysphoric behaviours. Mothers' responses to adolescents' aggressive and dysphoric behaviours may differentially influence the risk of MDD onset for adolescents over time.

    Objectives: To compare the coping strategies of adolescents with borderline personality disorder (BPD) to the coping strategies of adolescents without BPD, and to explore the association of coping with suicidal ideation and attempts among adolescents with BPD. Method: Adolescent inpatients (n = 167) aged 13 to 17 years were admitted after suicide attempts and evaluated within 10 days, using the abbreviated version of the Diagnostic Interview for Borderlines–Revised, the Schedule for Affective Disorders and Schizophrenia for School-Age Children–Present and Lifetime Version supported by a team consensus best estimate method for the primary diagnosis, the Adolescent Coping Scale, and the Columbia-Suicide Severity Rating Scale. Results: Firstly, compared with adolescents without BPD, adolescents with BPD relied more on nonproductive coping strategies, mostly avoidant strategies, and less on productive coping strategies. Secondly, coping appeared as a factor associated with suicidal ideation in adolescents with BPD. While while controlling for age, sex, and depression, multivariate analyses showed a significant positive association between the coping strategy to focusing on solving the problem and suicidal ideation. Conclusion: The use of avoidant strategies by adolescents with BPD could be viewed as attempts to increase emotional regulation. Problem-solving strategies in the immediate aftermath of a suicide attempt may prevent adolescents with BPD from overcoming a crisis and may increase suicidal ideation. PMID:25886671

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

    Research on immigrant families often has suggested that the process of immigration can lead to a distancing of adolescents and their parents. This study examined the actual agreement of immigrant and native mother-adolescent dyads in their reports on children's disclosure as an indicator for a trusting mother-child relationship. The research questions related to group-level differences (immigrant vs. native dyads) in mother-adolescent agreement, the prediction of interdyadic differences in mother-adolescent agreement, and the associations between mother-adolescent agreement and both family conflicts and adolescents' depressive symptoms. The sample was comprised of mother-adolescent dyads: 197 native German dyads (adolescents: mean age 14.7 years, 53% female) and 185 immigrant dyads from the former Soviet Union (adolescents: mean age 15.7 years, 60% female). Agreement was assessed using the intraclass correlation coefficient. The results revealed that mother-adolescent agreement was lower in immigrant dyads than in native dyads. In both samples, higher levels of adolescent autonomy predicted lower mother-adolescent agreement. Among immigrants, language brokering was an additional predictor of lower levels of mother-adolescent agreement. The interaction of language brokering and autonomy also turned out to be significant, indicating that if an adolescent was high in language brokering or autonomy, the effect of the other variable was negligible. In both groups, mother-adolescent agreement was negatively related to family conflicts. The study shows that processes in immigrant and native families are rather similar, but that in immigrant families some additional acculturation-related factors have to be considered for a full understanding of family dynamics.

    Background Obese youth are at increased risk for peer victimization, which may heighten their risk of psychosocial problems and physical activity avoidance, and lower the effectiveness of professional and lifestyle weight-loss initiatives. Little is known about obese adolescents’ risk for victimization from cyber-bullying and how this relates to psychosocial functioning and healthy lifestyle barriers. The purpose of the study was to assess traditional and cyber-victimization among adolescents with severe obesity and its relation to psychosocial distress and barriers to healthy lifestyles. Methods A sample of 102 obese adolescents (mean age = 15.32 ±1.71) in residential treatment was matched with 102 normal-weight youngsters from the Health Behavior in School-aged Children (HBSC) study (mean age = 15.30 ±1.73). Results Adolescents with obesity were significantly more often cyber-victimized than normal-weight peers. Obese youth victimized by traditional bullying experienced lower quality of life, lower motivation for physical activity and higher avoidance and emotional coping towards healthy lifestyles than those non-victimized. Obese cyber-victims experienced significantly higher suicidal ideation. Conclusions Traditional and cyber-victimization may hinder treatment effectiveness and healthy lifestyle change in adolescents with obesity. Health professionals should pro-actively address peer victimization and psychosocial functioning during multidisciplinary obesity treatment. Schools could contribute to a better physical and psychosocial health of obese youth by implementing multi-behavioral health-promotion programs. PMID:24593118

    This study examined the relationship between parental and adolescent eHealth literacy and its impact on online health information seeking. Data were obtained from 1,869 junior high school students and 1,365 parents in Taiwan in 2013. Multivariate analysis results showed that higher levels of parental Internet skill and eHealth literacy were associated with an increase in parental online health information seeking. Parental eHealth literacy, parental active use Internet mediation, adolescent Internet literacy, and health information literacy were all related to adolescent eHealth literacy. Similarly, adolescent Internet/health information literacy, eHealth literacy, and parental active use Internet mediation, and parental online health information seeking were associated with an increase in adolescent online health information seeking. The incorporation of eHealth literacy courses into parenting programs and school education curricula is crucial to promote the eHealth literacy of parents and adolescents.

    This study analyses two models (maternal and paternal) in which parental care and sources of parental knowledge moderated the relationship between parents' knowledge about their adolescents' lives and adolescents' substance use and health-related quality of life. The sample was made up of 15942 Spanish adolescents who participated in the 2006 edition of Health Behavior in School-aged Children Study. Results showed that increased parents' knowledge about their adolescents' lives reduced adolescents' substance use and increased their quality of life. With respect to the moderation relationship, a limited effect was found. However, parental care and sources of parental knowledge used by both parents generally had main effects on adolescents' substance use and health-related quality of life, with care being the most relevant variable in the health-related quality of life, while knowledge was the most relevant one for substance use.

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

    Adolescents have an increased need to regulate their behavior as they gain access to opportunities for risky behavior; however, cognitive control systems necessary for this regulation remain relatively immature. Parents can impact their adolescent child's abilities to regulate their behavior and engagement in risk taking. Since adolescents undergo significant neural change, negative parent-child relationship quality may impede or alter development in prefrontal regions subserving cognitive control. To test this hypothesis, 20 adolescents completed a go/nogo task during two fMRI scans occurring 1 year apart. Adolescents reporting greater family conflict and lower family cohesion showed longitudinal increases in risk-taking behavior, which was mediated by longitudinal increases in left VLPFC activation during cognitive control. These results underscore the importance of parent-child relationships during early adolescence, and the neural processes by which cognitive control may be derailed and lead to increased risk taking.

    2015-01-01

    Adolescence is often viewed as a time of irrational, risky decision-making – despite adolescents' competence in other cognitive domains. In this study, we examined the strategies used by adolescents (N=30) and young adults (N=47) to resolve complex, multi-outcome economic gambles. Compared to adults, adolescents were more likely to make conservative, loss-minimizing choices consistent with economic models. Eye-tracking data showed that prior to decisions, adolescents acquired more information in a more thorough manner; that is, they engaged in a more analytic processing strategy indicative of trade-offs between decision variables. In contrast, young adults' decisions were more consistent with heuristics that simplified the decision problem, at the expense of analytic precision. Collectively, these results demonstrate a counter-intuitive developmental transition in economic decision making: adolescents' decisions are more consistent with rational-choice models, while young adults more readily engage task-appropriate heuristics.

    Insomnia is the most prevalent sleep disorder in adolescents. A number of studies have evaluated the efficacy of the management of chronic insomnia in adults. Behavioral therapy for insomnia is the treatment of first choice, encompassing education about sleep and sleep hygiene, stimulus control, relaxation techniques, and cognitive strategies to combat nocturnal ruminations. Special programs for adolescents are lacking. In this study an age-oriented treatment program for adolescents (JuSt) was developed and evaluated. Eighteen adolescents and their parents participated in a psychological short-term treatment comprising six sessions. First results show that the treatment was well accepted by the adolescents and their parents and led to a significant reduction in sleep problems, such as sleep onset, sleep efficacy, sleep duration, and feeling rested as well as in cognitive parameters, such as ruminations and mental health. Randomized controlled studies are needed to evaluate the efficacy of this new approach to treat insomnia in adolescents.

    The relationship of parenting styles with adolescents' outcomes was analyzed within a sample of Spanish adolescents. A sample of 1456 teenagers from 13 to 16 years of age, of whom 54.3% were females, reported on their parents' child-rearing practices. The teenagers' parents were classified into one of four groups (authoritative, authoritarian, indulgent, or neglectful). The adolescents were then contrasted on two different outcomes: (1) priority given to Schwartz's self-transcendence (universalism and benevolence) and conservation (security, conformity, and tradition) values and (2) level of self-esteem (appraised in five domains: academic, social, emotional, family and physical). The results show that Spanish adolescents from indulgent households have the same or better outcomes than adolescents from authoritative homes. Parenting is related with two self-esteem dimensions--academic and family--and with all the self-transcendence and conservation values. Adolescents of indulgent parents show highest scores in self-esteem whereas adolescents from authoritarian parents obtain the worst results. In contrast, there were no differences between the priority given by adolescents of authoritative and indulgent parents to any of the self-transcendence and conservation values, whereas adolescents of authoritarian and neglectful parents, in general, assign the lowest priority to all of these values.

    Spatial abilities allow animals to retain and cognitively manipulate information about their spatial environment and are dependent upon neural structures that mature during adolescence. Exposure to stress in adolescence is thought to disrupt neural maturation, possibly compromising cognitive processes later in life. We examined whether exposure to chronic unpredictable stress in adolescence affects spatial ability in late adulthood. We evaluated spatial learning, reference and working memory, as well as long-term retention of visuospatial cues using a radial arm water maze. We found that stress in adolescence decreased the rate of improvement in spatial learning in adulthood. However, we found no overall performance impairments in adult reference memory, working memory, or retention caused by adolescent-stress. Together, these findings suggest that adolescent-stress may alter the strategy used to solve spatial challenges, resulting in performance that is more consistent but is not refined by incorporating available spatial information. Interestingly, we also found that adolescent-stressed rats showed a shorter latency to begin the water maze task when re-exposed to the maze after an overnight delay compared with control rats. This suggests that adolescent exposure to reoccurring stressors may prepare animals for subsequent reoccurring challenges. Overall, our results show that stress in adolescence does not affect all cognitive processes, but may affect cognition in a context-dependent manner.

    Thalassemia is an autosomal recessive inherited blood disorder. It is prevalent in Mediterranean countries such as Sardinia, Greece, Cyprus, Turkey, Lebanon and also Southeast Asia. Our aim was to investigate the carrier prevalence of thalassemia and other hemoglobinopathies in adolescents who live in Muğla Province, Turkey. We analyzed retrospectively the surveys conducted at primary schools between 1997 and 2013. Complete blood count (CBC) and high performance liquid chromatography (HPLC) were used to screen for thalassemia and hemoglobinopathies. Patients were diagnosed as having thalassemia trait if the mean corpuscular volume (MCV) was ≤ 80.0 fL, mean corpuscular hemoglobin (Hb) was ≤ 27.0 pg and Hb A2 levels were ≥ 3.5%. A total of 164,814 students were analyzed. The median age of the students was 13.5 years (minimum 13.0, maximum 14.0). The total number of students with abnormal HPLC results was 5861 (3.8%). There was a significant decrease in the newborn of new thalassemia patients found with screening programs for hemoglobinopathies in Muğla Province from 1997 to 2013. The number of students with abnormal HPLC results for thalassemia, sickle cell disease and other Hb traits were 3.2, 0.15 and 0.4%, respectively. It is important to recognize that including Hb, MCV, red blood cell (RBC) count and HPLC tests for carrier screening are necessary to find hemoglobinopathies. Our study supported that the number of new patients significantly decreased using these screening programs from 1997 to 2013.

    Previous studies have shown that birth weight and other birth characteristics may be associated with risk for type 2 diabetes and cardiovascular disease (CVD) later in life; however, results using large US national survey data are limited. Our goal was to determine the aforementioned associations using nationally representative data. We studied children and adolescents 6-15 years using data from the National Health and Nutrition Examination Survey cycles 2001-2010. Survey and examination data included demographic and early childhood characteristics, current health status, physical activity information, anthropometric measurements, dietary data (total energy, saturated fat, sodium, and sugar intakes), biomarkers related to selected risk factors of CVD [systolic blood pressure (SBP), plasma C-reactive protein (CRP) and lipid profiles], and type 2 diabetes [fasting glucose, insulin, and homeostasis model assessment (HOMA)]. Birth weight (proxy-reported) was inversely associated with SBP among girls; SBP levels increased 1.4 mmHg for each 1,000 g decrease in birth weight (p = 0.003) after controlling for potential confounders. Birth weight was not associated with levels of CRP or lipid profiles across the three racial groups. In addition, birth weight was inversely related to levels of fasting insulin and HOMA among non-Hispanic Whites; for each 1,000 g decrease in birth weight, fasting insulin levels increased 9.1% (p = 0.007) and HOMA scores increased 9.8% (p = 0.007). Birth weight was inversely associated with the levels of SBP, fasting insulin, and HOMA. These results support a role for birth weight, independent of the strong effects of current body weight status, in increasing risk for CVD and type 2 diabetes.

    Objective Our objectives were: to assess the QOL of Brazilian adolescents with epilepsy with a specific QOL assessment tool; to compare the adolescents with epilepsy and healthy adolescents using a generic QOL assessment tool; to correlate the 2 different QOL assessment tools (the generic and the epilepsy-specific); and to correlate QOL scores of the adolescents with epilepsy obtained by both tools with physical, psychological and social variables of the disease. Methods Fifty subjects (case group) attending the outpatient clinic of epilepsy of the Clinics Hospital of UNICAMP, Campinas-SP, answered the Brazilian version of the QOL inventory for adolescents with epilepsy - QOLIE-AD-48 and the QOL Questionnaire - WHOQOL – BREF – Portuguese version. Fifty-one subjects (control group) from public schools in Campinas-SP answered only the WHOQOL-BREF. Results The results showed that adolescents with epilepsy presented a good score of QOL in both tools; overall scores for both groups with WHOQOL-BREF were good, but a statistically significant difference was seen with regards to the Psychological domain of the WHOQOL-BREF favoring the control group. Significant correlations between QOLIE-AD-48 Total and WHOQOL domains were found. Adolescents that were considered seizure-free (P = 0.001), had good perception of seizure control (P = 0.012) and had not had occurrence of seizures in public places (P = 0.001) presented better QOL scores. Conclusions Brazilian adolescents with epilepsy may present good QOL scores when they themselves consider the disease as under control; physical, social and especially psychological variables associated to the disease may play an important role in these results. As a generic QOL tool, WHOQOL-BREF was sufficient to allow for a comparison between chronic disease bearers and healthy adolescents and showed that the gap in QOL between both populations is not as extensive as once was thought, probably due to better support and

  19. Smoking in movies: impact on adolescent smoking.

    Sargent, James D

    2005-06-01

    This article examines the evidence that supports an association between seeing smoking depictions in movies and adolescent smoking. The portrayal of tobacco use is common in movies and often is modeled by stars, who, from a social influences standpoint, should be powerful behavior change agents. The results of studies that assess audience responses to tobacco portrayal in movies are remarkably consistent in showing a moderate to strong association between seeing movie smoking and more positive attitudes toward smoking and adolescent smoking initiation. The two published longitudinal studies show an independent link between exposure to movie smoking at baseline and initiation in the future, with estimates of the effect size being remarkably consistent with their cross-sectional counterparts. Pediatricians should support public health campaigns to pressure the movie industry to voluntarily reduce smoking in movies and encourage parents to adhere to the Motion Picture Ratings System to reduce adolescent exposure to this powerful social influence to smoke.

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

    Rapid social changes in current times which can be quite abrupt present a challenge to adolescent life. Adolescents who are unable to adapt themselves experience stress which may affect their health. Psychological issues of adolescents require attention because the long-term consequence is worse than the short-term effects, namely, there will be a group of people within society who live under stress. Stressed people show symptoms such as being aggressive, prone to rebel, uncontrollable anger, depression, mental disorders and health problems. Early recognition of adolescent stress symptoms is vital. Pursuant to this, a study is conducted among adolescents in Kajang, Selangor, Malaysia for the purpose of determining whether they experience stress or otherwise, based on stress symptoms in terms of psychology, physiology and social behaviour. An analysis is conducted on 403 respondents who comprise of male and female adolescents aged 16-17 years. The required data are gathered through questionnaire and structured interview. Analysis is based on descriptive statistical method and is explained in a table in terms of frequency, percentage and mode. Research results show that adolescents do experience stress and that the majority of them exhibit psychological stress symptoms.

    The Internet offers adolescents unique opportunities to actively shape their own sexual media environment. The aim of this study was to gain in-depth insight into Dutch adolescents' motives, perceptions, and reflections toward Internet use for (a) finding information or advice related to romance and sexuality; (b) searching for and viewing pornographic or erotic material; and (c) romantic and sexual communication (i.e., cybersex/sexting). Data were collected through 12 Web-based focus groups (36 adolescents aged 16 to 19 years, 72.2% girls) and analyzed through three stages of open, axial, and selective coding. The themes that emerged from the focus-group discussions suggest that sex-related Internet use is a complex and ambivalent experience for adolescents. Sex-related Internet use seems an increasingly normalized and common phenomenon. Participants perceived the Internet as a useful source of sexual information, stimulation, inspiration, and communication. Yet they discussed a range of negative consequences and risks related to sex-related online behaviors, particularly concerning pornography's potential to create unrealistic expectations about sex and sexual attractiveness. Participants generally believed they had the necessary skills to navigate through the online sexual landscape in a responsible way, although they believed other young people could be influenced inadvertently and adversely by sex-related online content.

    Al-Adhami, Maissa

    2015-01-01

    Introduction: Studies of social characteristics and substance use patterns among young users of water pipe are rare in Western countries, and no such study has been conducted in Sweden. Methods: Cross-sectional study based on a national survey conducted in 2011, including 4,710 primary school students (15 years of age) and 3,624 high school students (17 years of age). Prevalence of lifetime and current water pipe use was compared among subgroups defined by other substance use, that is, cigarettes, snus, alcohol, and illicit drugs. Logistic regression was employed to calculate odds ratios (OR) of water pipe use and corresponding 95% confidence intervals (CI), conditionally on sociodemographic characteristics. Results: Use of water pipe was associated with the use of other substances in both age groups. In particular, current use of water pipe at the age of 15 years was strongly associated with current cigarette smoking (OR = 6.46; CI = 5.13–8.14); use of snus (OR = 5.62; CI = 3.94–7.96); binge drinking (OR = 7.39; CI = 5.88–9.31); drunkenness (OR = 7.05; CI = 5.60–8.88); and recent use of illicit drugs (OR = 14.20; CI = 9.18–22.19). Annual alcohol consumption predicted water pipe use in a dose–response fashion. Cigarette smokers willing to quit used water pipe to a lower extent than smokers who did not intend to quit. Being an exclusive smoker of water pipe was associated with substance use when compared with a nonsmoker of tobacco, but not when compared with an exclusive smoker of cigarettes. Conclusions: Water pipe use among adolescents in Sweden is not a recreational tobacco use alternative to cigarettes and should be regarded as a marker of multiple substance use. PMID:25140043

    Background Polyunsaturated n-3 and n-6 polyunsaturated fatty acids (PUFA) are precursors of biologically active metabolites that affect blood pressure (BP) regulation. This study investigated the association of n-3 and n-6 PUFA and BP in children and adolescents. Methods In a subsample of 1267 children aged 2–9 years at baseline of the European IDEFICS (Identification and prevention of dietary- and lifestyle-induced health effects in children and infants) cohort whole blood fatty acids were measured by a validated gas chromatographic method. Systolic and diastolic BP was measured at baseline and after two and six years. Mixed-effects models were used to assess the associations between fatty acids at baseline and BP z-scores over time adjusting for relevant covariables. Models were further estimated stratified by sex and weight status. Results The baseline level of arachidonic acid was positively associated with subsequent systolic BP (β = 0.08, P = 0.002) and diastolic BP (β = 0.07, P<0.001). In thin/normal weight children, baseline alpha-linolenic (β = -1.13, P = 0.003) and eicosapentaenoic acid (β = -0.85, P = 0.003) levels were inversely related to baseline and also to subsequent systolic BP and alpha-linolenic acid to subsequent diastolic BP. In overweight/obese children, baseline eicosapentaenoic acid level was positively associated with baseline diastolic BP (β = 0.54, P = 0.005). Conclusions Low blood arachidonic acid levels in the whole sample and high n-3 PUFA levels in thin/normal weight children are associated with lower and therefore healthier BP. The beneficial effects of high n-3 PUFA on BP were not observed in overweight/obese children, suggesting that they may have been overlaid by the unfavorable effects of excess weight. PMID:27806134

    Background Theory and treatment of anxiety disorders in young people are commonly based on the premise that interpretation biases found in anxious adults are also found in children and adolescents. Although there is some evidence that this may be the case, studies have not typically taken age into account, which is surprising given the normative changes in cognition that occur throughout childhood. The aim of the current study was to identify whether associations between anxiety disorder status and interpretation biases differed in children and adolescents. Methods The responses of children (7–10 years) and adolescents (13–16 years) with and without anxiety disorders (n=120) were compared on an ambiguous scenarios task. Results Children and adolescents with an anxiety disorder showed significantly higher levels of threat interpretation and avoidant strategies than non-anxious children and adolescents. However, age significantly moderated the effect of anxiety disorder status on interpretation of ambiguity, in that adolescents with anxiety disorders showed significantly higher levels of threat interpretation and associated negative emotion than non-anxious adolescents, but a similar relationship was not observed among children. Conclusions The findings suggest that theoretical accounts of interpretation biases in anxiety disorders in children and adolescents should distinguish between different developmental periods. For both ages, treatment that targets behavioral avoidance appears warranted. However, while adolescents are likely to benefit from treatment that addresses interpretation biases, there may be limited benefit for children under the age of ten. PMID:26363617

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

    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

    Graffiti has been studied for many years from many viewpoints. They have been used to explain accounts of people, styles of life, and assumed relationships. The present paper reports an attempt to analyze graffiti as outward manifestations of adolescent personality. Results suggested that different forms of graffiti could be interpreted from five characterizations of early adolescent personality: sexual maturity, self-identity, idealism, iconoclasm, and rebelliousness. Significant differences were found between boys and girls in numbers of inscriptions for each category. Further, the graffiti were analyzed in relation to early adolescent stages of development.

    Chronic migraine is defined as having more than 15 headache days in a month, half of these showing migraine features, for at least 3 months. It is a chronic painful syndrome with aspects such as psychiatric comorbid, decreased quality of life, and environmental and intrinsic psychological factors that make face-to-face treatment difficult. Children and adolescent migraine differ from adults as a result of growing brain and evolving disorder. In this paper, we will emphasize the definition, diagnosis, epidemiology, burden of life, and management of chronic migraine in children and adolescent.

    Whereas a large literature has shown the importance of early life health for adult socioeconomic outcomes, there is little evidence on the importance of adolescent health. We contribute to the literature by studying the impact of adolescent health status on adult labor market outcomes using a unique and large-scale dataset covering almost the entire population of Swedish males. We show that most types of major conditions have long-run effects on future outcomes, and that the strongest effects result from mental conditions. Including sibling fixed effects or twin pair fixed effects reduces the magnitudes of the estimates, but they remain substantial.

    The present study examined longitudinal acculturation patterns, and their associations with family functioning and adolescent risk behaviors, in Hispanic immigrant families. A sample of 266 Hispanic adolescents (mean age 13.4) and their primary parents completed measures of acculturation, family functioning, and adolescent conduct problems, substance use, and sexual behavior at five timepoints. Mixture models yielded three trajectory classes apiece for adolescent and parent acculturation. Assimilated adolescents reported the poorest family functioning, but adolescent assimilation negatively predicted adolescent cigarette smoking, sexual activity, and unprotected sex indirectly through family functioning. Follow-up analyses indicated that discrepancies between adolescent and parent family functioning reports predicted these adolescent outcomes. Results are discussed regarding acculturation trajectories, adolescent risk behavior, and the mediating role of family functioning. PMID:23848416

    In the second half of the 19th century, Jean-Martin Charcot (1825-1893) became famous for the quality of his teaching and his innovative neurological discoveries, bringing many French and foreign students to Paris. A hunger for recognition, together with progressive and anticlerical ideals, led Charcot to invite writers, journalists, and politicians to his lessons, during which he presented the results of his work on hysteria. These events became public performances, for which physicians and patients were transformed into actors. Major newspapers ran accounts of these consultations, more like theatrical shows in some respects. The resultant enthusiasm prompted other physicians in Paris and throughout France to try and imitate them. We will compare the form and substance of Charcot's lessons with those given by Jules-Bernard Luys (1828-1897), Victor Dumontpallier (1826-1899), Ambroise-Auguste Liébault (1823-1904), Hippolyte Bernheim (1840-1919), Joseph Grasset (1849-1918), and Albert Pitres (1848-1928). We will also note their impact on contemporary cinema and theatre.

    Alcohol use during adolescence leads to increased risk of developing an alcohol use disorder (AUD) during adulthood. Converging evidence suggests that this period of enhanced vulnerability for developing an AUD may be due to the adolescent's unique sensitivity and response to alcohol. Adolescent rats have been shown to be less sensitive to alcohol intoxication and withdrawal susceptibility; however, age differences in ethanol pharmacokinetics may underlie these effects. Therefore, this study investigated alcohol intoxication behavior and withdrawal severity using a modified Majchrowicz model of alcohol dependence that has been shown to result in similar blood ethanol concentrations (BECs) despite age differences. Adolescent (postnatal day, PND, 35) and adult rats (PND 70+) received ethanol according to this 4-day binge paradigm and were observed for withdrawal behavior for 17h. As expected, adolescents showed decreased sensitivity to alcohol-induced CNS depression as evidenced by significantly lower intoxication scores. Thus, adolescents received significantly more ethanol each day (12.3+/-0.1g/kg/day) than adults (9.2+/-0.2g/kg/day). Despite greater ethanol dosing in adolescent rats, both adolescent and adult groups had comparable peak BECs (344.5+/-10.2 and 338.5+/-7.8mg/dL, respectively). Strikingly, withdrawal severity was similar quantitatively and qualitatively between adolescent and adult rats. Further, this is the first time that withdrawal behavior has been reported for adolescent rats using this model of alcohol dependence. A second experiment confirmed the similarity in BECs at various time points across the binge. These results demonstrate that after consideration of ethanol pharmacokinetics between adults and adolescents by using a model that produces similar BECs, withdrawal severity is nearly identical. This study, in combination with previous reports on ethanol withdrawal in adolescents and adults, suggests only a BEC-dependent effect of ethanol on

    Aim To determine an impact of parental divorce to depression and intimate relationships of young people during adolescence, and prevalence of symptoms of depression and the level of intimacy in relations to adolescents living in intact families and those from divorced families. Methods This prospective descriptive research was conducted on a sample of 168 examinees of which 64 (38.1%) were students of the University Zenica, and 104 (61.9%) high students schools from Zenica and Maglaj cities during May and June 2011. Beck's Depression Inventory (BDI) II, Miller Social Intimacy Scale and sociodemographic questionnaire were used. Results Adolescents from divorced families had statistically significantly higher level of depression (p<0.05), with moderate and severe depression found in 20 (24.69%) adolescents from divorced families as compared with six (6.89%) adolescents from intact families. An analysis of BDI-II scale showed that adolescents from divorced families had statistically significant difference in agitation(p<0.01), difficult concentration, suicidal thoughts, grief and pessimism (p<0.05). Conclusion It is necessary to carry out detailed studies on longterm effects of breakup of families due to divorce, which have negative implications on psychological and social functioning of adolescents and the development of their identity and closeness in intimate relationships, with a legislative introduction of premarital and marriage counseling for parents in the conflict.

    Previous studies have suggested that parental criticism leads to more somatic symptoms in adolescent children. Yet this research has not assessed the direction of causation or whether genetic and/or environmental influences explain the association between parental criticism and adolescent somatic symptoms. As such, it is impossible to understand the mechanisms that underlie this association. The current study uses the Extended Children of Twins design to examine whether parents’ genes, adolescents’ genes, and/or environmental factors explain the relationship between parental criticism and adolescent somatic symptoms. Participants came from two twin samples, including the Twin and Offspring Study in Sweden (N = 868 pairs of adult twins and each twin’s adolescent child) and from the Twin Study of Child and Adolescent Development (N = 690 pairs of twin children and their parents). Findings showed that environmental influences account for the association between parental criticism and adolescent somatic symptoms. This suggests that parents’ critical behaviors exert a direct environmental effect on somatic symptoms in adolescent children. Results support the use of intervention programs focused on parental criticism to help reduce adolescents’ somatic symptoms. PMID:25844495

    Background: Pregnancy rate among Iranian adolescents below 20 years of age is increasing. Pregnancy during adolescence is considered a social issue associated with medical, emotional, and social outcomes for the mother, child, and family. The current research examines the experience of pregnancy among Iranian adolescents. Materials and Methods: The qualitative content analysis method was used. A purposive sample of 14 pregnant adolescents was enrolled in the study. Deep interviews were carried out with them. Results: Three themes were came up after analyzing the interviews: 1. Psychological reactions including three subthemes of feelings, concerns, and fears; 2. physical reactions including the subthemes of symptoms and feelings; and 3. spiritual reactions including religious beliefs and faith. Conclusions: The present study showed that for the purpose of assessing pregnancy in adolescents, one should consider the context and culture in which the adolescent lives. This is because factors such as preplanned or unwanted pregnancy and imposed or consensual marriage within or outside the family may draw different reactions from adolescents. Hence, all those factors need to be considered in order to plan health education during pregnancy for this age group. PMID:25949255

    Childhood maltreatment (CM) has been associated with diminished executive functioning in children and adults; however, there is a relative paucity of study of executive function in adolescents exposed to CM. Yet, executive dysfunction in adolescence may have important adverse consequences including increased vulnerability to risky behaviors and impaired school functioning. This study investigates the relationship between self-reported CM and an executive function, cognitive flexibility, in adolescents without identified psychiatric disorders. Effects of physical and emotional, abuse and neglect, maltreatment subtypes were explored. Thirty adolescents ages 12-17 years, 50% females, completed the retrospective self-report Childhood Trauma Questionnaire (CTQ) and were administered the Wisconsin Card Sorting Test (WCST). Correlational analyses assessed the relationship between WCST perseverative error scores norm-referenced for age and education with CTQ total scores. The relationship with nonperseverative errors, as well as with physical and emotional abuse and neglect CM subscores, were explored. Total CTQ scores showed significant associations with perseverative errors on the WCST, but not with nonperseverative errors. Significant associations with perseverative errors were seen for physical abuse and physical neglect among the CTQ subscales. The results suggest both physical abuse and physical neglect are associated with diminished cognitive flexibility in adolescents. These effects were detected in adolescents without identified psychiatric diagnoses suggesting the importance of considering executive dysfunction in adolescents exposed to CM who may not meet diagnostic criteria for an Axis I disorder and that tests of perseverative errors, such as those of the WCST, may be sensitive indicators of this dysfunction.

    Background Since stress is hypothesized to play a role in the etiology of obesity during adolescence, research on associations between adolescent stress and obesity-related parameters and behaviours is essential. Due to lack of a well-established recent stress checklist for use in European adolescents, the study investigated the reliability and validity of the Adolescent Stress Questionnaire (ASQ) for assessing perceived stress in European adolescents. Methods The ASQ was translated into the languages of the participating cities (Ghent, Stockholm, Vienna, Zaragoza, Pecs and Athens) and was implemented within the HELENA cross-sectional study. A total of 1140 European adolescents provided a valid ASQ, comprising 10 component scales, used for internal reliability (Cronbach α) and construct validity (confirmatory factor analysis or CFA). Contributions of socio-demographic (gender, age, pubertal stage, socio-economic status) characteristics to the ASQ score variances were investigated. Two-hundred adolescents also provided valid saliva samples for cortisol analysis to compare with the ASQ scores (criterion validity). Test-retest reliability was investigated using two ASQ assessments from 37 adolescents. Results Cronbach α-values of the ASQ scales (0.57 to 0.88) demonstrated a moderate internal reliability of the ASQ, and intraclass correlation coefficients (0.45 to 0.84) established an insufficient test-retest reliability of the ASQ. The adolescents' gender (girls had higher stress scores than boys) and pubertal stage (those in a post-pubertal development had higher stress scores than others) significantly contributed to the variance in ASQ scores, while their age and socio-economic status did not. CFA results showed that the original scale construct fitted moderately with the data in our European adolescent population. Only in boys, four out of 10 ASQ scale scores were a significant positive predictor for baseline wake-up salivary cortisol, suggesting a rather poor

    This is a qualitative research based on the social phenomenology approach, performed in 2010 with eight adolescents who experienced abortion and were assisted in a philanthropic hospital institution in the state of Minas Gerais. This research aimed at understanding the experience and care needs regarding adolescents in an abortion situation. The results show that the pregnancy impact led to the fear of non acceptance by the family and at the same time, the feeling of happiness for the possibility of being a mother. The abortion experience was marked by suffering and the care provided was considered satisfactory, being highlighted the need for more attention and information. The adolescents plan to continue their studies and have in mind the possibility of a new pregnancy. The planning of preventive actions aimed at this audience, and the development of new scientific investigations that include the perspective of family members and health professionals begin to emerge.

    IMPORTANCE Many adolescents and young adults use alternative tobacco products, such as water pipes and snus, instead of cigarettes. OBJECTIVE To assess whether prior water pipe tobacco smoking and snus use among never smokers are risk factors for subsequent cigarette smoking. DESIGN, SETTING, AND PARTICIPANTS We conducted a 2-wave national longitudinal study in the United States among 2541 individuals aged 15 to 23 years old. At baseline (October 25, 2010, through June 11, 2011), we ascertained whether respondents had smoked cigarettes, smoked water pipe tobacco, or used snus. At the 2-year follow-up (October 27, 2012, through March 31, 2013), we determined whether baseline non–cigarette smokers had subsequently tried cigarette smoking, were current (past 30 days) cigarette smokers, or were high-intensity cigarette smokers. We fit multivariable logistic regression models among baseline non–cigarette smokers to assess whether baseline water pipe tobacco smoking and baseline snus use were associated with subsequent cigarette smoking initiation and current cigarette smoking, accounting for established sociodemographic and behavioral risk factors. We fit similarly specified multivariable ordinal logistic regression models to assess whether baseline water pipe tobacco smoking and baseline snus use were associated with high-intensity cigarette smoking at follow-up. EXPOSURES Water pipe tobacco smoking and the use of snus at baseline. MAIN OUTCOMES AND MEASURES Among baseline non–cigarette smokers, cigarette smoking initiation, current (past 30 days) cigarette smoking at follow-up, and the intensity of cigarette smoking at follow-up. RESULTS Among 1596 respondents, 1048 had never smoked cigarettes at baseline, of whom 71 had smoked water pipe tobacco and 20 had used snus at baseline. At follow-up, accounting for behavioral and sociodemographic risk factors, baseline water pipe tobacco smoking and snus use were independently associated with cigarette smoking

    Background Long-term exposure to arsenic is a major public health concern. Emerging evidence suggests adverse health effects even at low levels of exposure. This study examined the association of arsenic exposure with estimated glomerular filtration rate (eGFR) and compared methods of adjustment for urinary dilution in a representative sample of U.S. adolescents and young adults. Methods We performed a cross-sectional study of 1,253 participants ages 12–30 years in the 2009–2012 National Health and Nutrition Examination Survey (NHANES) with available urinary arsenic and eGFR measures. Multivariable linear regression was used to model the association of urinary total arsenic and dimethylarsinate (DMA) with eGFR. Results The median urinary total arsenic and DMA concentrations were 6.3 μg/L (IQR 3.3 – 12.7 μg/L) and 3.3 μg/L (IQR 1.7 – 5.7 μg/L), respectively. Median eGFR was 109 mL/min/1.73 m2. Adjusting arsenic for urine concentration with urinary creatinine, eGFR was 4.0 mL/min/1.73 m2 higher (95% confidence interval [CI] 1.0 to 7.1 mL/min/1.73 m2) and 4.3 mL/min/1.73 m2 higher (95% CI 0.5 to 8.0 mL/min/1.73 m2) per log-unit increase in total arsenic and DMA, respectively. When using urine osmolality to adjust for urine concentration, a log-unit increase in total arsenic and DMA was associated with a 0.4 mL/min/1.73 m2 (95% CI −1.8 to 1.1 mL/min/1.73 m2) and 0.01 (95% CI −1.9 to 1.9 mL/min/1.73 m2) lower eGFR, respectively. Conclusions Discordant associations were observed between arsenic and eGFR levels depending on whether urinary creatinine or osmolality was used to adjust for urine concentration. Further study should be dedicated to validating the best approach to account for urinary dilution in research in toxicants, and this may have implications for all studies which examine urinary biomarkers.

    The stability of abortion opinions suggests that pre-adult factors influence these attitudes more than contemporaneous political events. Surprisingly, however, we know little about the origins of abortion opinions, no doubt because the majority of research focuses on cross-sectional analyses of patterns across cohorts. We use a developmental model that links familial and contextual factors during adolescence to abortion attitudes years later when respondents are between 21 and 38 years old. Findings show that religious adherence and maternal gender role values are significant predictors of adult abortion opinions, even after controlling for contemporaneous religious adherence and the respondents’ own views on gender roles. Adolescent religious adherence matters more than religious denomination for adult abortion attitudes. The results have important implications for future trends in abortion attitudes in light of declining religiosity among Americans. PMID:27257307

    Living with a chronic condition (CC) in adolescence has been historically considered protective for risk behaviours. However, research from the last decade suggest that when compared with healthy peers, adolescents living with a chronic condition can engage in risky behaviours in a similar if not higher rate than their counterparts living with out a CC. This study aims to characterize and evaluate the impact of 1) living with a chronic condition (CC), and 2) how the perception of living with a CC affects school participation, and its association with risk/protective behaviours (drunkenness, physical fight, sadness and self-harm). For this purpose 4 groups were identified: adolescents with mostly healthy behaviours, adolescents with mostly risk behaviours, adolescents with mostly risk-internalizing behaviours and adolescents with mostly risk-externalizing behaviours. A large sample was included in this study, composed by 3494 Portuguese adolescents with an average age of 15 years, who participated in the Portuguese Survey of Health Behaviour in School-aged Children/WHO (HBSC). Main results show that adolescents living with a CC have more risk-internalizing behaviours when compared to adolescents without CC, who present more healthy behaviors. Furthermore, adolescents that report that having a CC affects school participation show more risky behaviours than those not affected by a CC who present more healthy behaviours. Boys with a CC show more healthy behaviours, and those who feel that the CC affects school participation present more risky behaviours. On the other hand, girls with a CC have more risk-internalizing behaviours and less healthy behaviours It is important to point out that dolescents living with a CC represent a vulnerable group, and may engage in experimental/risky behaviours as likely as their non CC peers. Thus, potential benefits can arise from reinforcing interventions within protective contexts (family/peers/school setting). Health

    Anhedonia—the reduced capacity to experience pleasure—is a trait implicated in mental and physical health. Yet, psychometric data on anhedonia measures in adolescents are absent. We conducted an in-depth psychometric analysis of the Snaith-Hamilton Pleasure Scale (SHAPS; Snaith et al., 1995)—a self-report measure of anticipated pleasure response to 14 pleasant experiences—in adolescents. Adolescents (N=585; M age=14.5) completed the SHAPS and other paper-and-pencil surveys. Item response theory models were used to evaluate the psychometric performance of each SHAPS item. Correlations of the SHAPS with other personality and psychopathology measures were calculated to evaluate construct validity. Results showed that: (1) certain items (e.g., reported pleasure from basic experiences like “seeing smiling faces” or “smelling flowers”) provided more information about latent anhedonia than others; and (2) SHAPS scales exhibited construct-consistent convergent and discriminant validity (i.e., stronger correlations with low positive affect constructs; weaker correlations with negative affect). Reporting diminished pleasure from basic pleasant experiences accurately indicates adolescent anhedonia, which is important for future scale development and understanding the phenomenology of anhedonia in teens. These data support using the SHAPS for assessing anhedonia in epidemiological research and school-based universal prevention programming in general adolescent populations. PMID:25893676

    Parents with a child suffering from psychosocial problems frequently experience barriers to psychosocial care, which may hinder access. Expectations of barriers may have the same effect, but evidence is lacking. The aim of this study is to examine parents' and adolescents' expectations of barriers regarding psychosocial care for the child, along with associated child and family characteristics. We obtained data on an age-stratified random sample of school children/pupils aged 4-18 via questionnaires (N = 666; response rate 70.3 %). Expectations of barriers to psychosocial care were measured with the "Barriers to Treatment Participation Scale-Expectancies" questionnaire (BTPS-exp). Results showed that 64 % of the parents of children below age 12, 59 % of the parents of adolescents (age 12-18), and 84 % of the adolescents expected one or more barriers. Parents and adolescents expected barriers most frequently with respect to irrelevance of treatment. Mainly parents with low educational level and their adolescents expected barriers regarding treatment, and quite a few characteristics of parents of adolescents were associated with expecting multiple barriers regarding treatment demands and issues, for example, single parents, parents of lower educational level and of adolescent boys, and parents of adolescents with psychosocial problems. We conclude that adolescents especially, but also their parents and parents of younger children, expect major barriers to psychosocial care, which may greatly hinder appropriate care seeking. This evidence may support professionals and policymakers in their attempts to improve access to psychosocial care.

    Adolescence is a crucial period for the development of adaptive emotion regulation strategies. Despite the fact that structural maturation of the prefrontal cortex during adolescence is often assumed to underlie the maturation of emotion regulation strategies, no longitudinal studies have directly assessed this relationship. This study examined whether use of cognitive reappraisal strategies during late adolescence was predicted by (i) absolute prefrontal cortical thickness during early adolescence and (ii) structural maturation of the prefrontal cortex between early and mid-adolescence. Ninety-two adolescents underwent baseline and follow-up magnetic resonance imaging scans when they were aged approximately 12 and 16 years, respectively. FreeSurfer software was used to obtain cortical thickness estimates for three prefrontal regions [anterior cingulate cortex; dorsolateral prefrontal cortex (dlPFC); ventrolateral prefrontal cortex (vlPFC)]. The Emotion Regulation Questionnaire was completed when adolescents were aged approximately 19 years. Results showed that greater cortical thinning of the left dlPFC and left vlPFC during adolescence was significantly associated with greater use of cognitive reappraisal in females, though no such relationship was evident in males. Furthermore, baseline left dlPFC thickness predicted cognitive reappraisal at trend level. These findings suggest that cortical maturation may play a role in the development of adaptive emotion regulation strategies during adolescence.

    Building on self-determination theory (Deci and Ryan in Psychological Inquiry, 11, 227-268. doi: 10.1207/S15327965PLI1104_01 , 2000), the aim of the current study was to examine the role of maternal affective and cognitive empathy in predicting adolescents' depressive symptoms, through mothers' psychological control use. Less empathic mothers may be less sensitive to adolescents' need for psychological autonomy, and thus prone to violating this need using psychological control, which may in turn predict adolescents' depressive symptoms. Moreover, according to interpersonal theory of depression (Coyne in Journal of Abnormal Psychology, 85, 186-193. doi: 10.1037/0021-843x.85.2.186 , 1976), adolescents' depressive symptoms may elicit rejecting responses, such as mothers' psychological control. For six waves, 497 adolescents (57 % boys, M age T1 = 13.03) annually completed questionnaires on depressive symptoms and maternal psychological control, while mothers reported on their empathy. Cross-lagged path analyses showed that throughout adolescence, both mothers' affective and cognitive empathy indirectly predicted boys' and girls' depressive symptoms, through psychological control. Additionally, depressive symptoms predicted psychological control for boys, and early adolescent girls. These results highlight the importance of (1) mothers' affective and cognitive empathy in predicting adolescents' depressive symptoms, and (2) taking gender into account when examining adolescent-effects.

    There are conflicting findings about whether adopted children have more psychological and behavioral problems than nonadoptees. Research results are discrepant partly because many previous studies were based on small clinical samples or on samples biased by self-selection. A nationally representative school survey (Add Health) was used to compare adopted (n = 1,587) and nonadopted adolescents (total N = 87,165) across a wide variety of measures. Standardized mean differences show that adopted adolescents are at higher risk in all of the domains examined, including school achievement and problems, substance use, psychological well-being, physical health, fighting, and lying to parents. Demographic and background variable breakdowns show that the effect sizes for differences between adopted and nonadopted adolescents were larger for males, younger or older adolescents, Hispanics or Asians, and adolescents living in group homes or with parents of low education. Distributional analyses revealed approximately a 1:1 ratio of adopted to nonadopted adolescents in the middle ranges of the outcome variables but a ratio of 3:1 or greater near the tails of the distributions. These data clearly show that more adopted adolescents have problems of various kinds than their nonadopted peers; effect sizes were small to moderate based on mean differences, but comparisons of distributions suggest much larger proportions of adopted than nonadopted adolescents at the extremes of salient outcome variables.

    Adolescent pregnancy, although on the decline, represents a significant public health concern. Often adolescents present late to prenatal care, either from lack of knowledge, fear of consequences, limited access, stigma, or all of the above. Although multifaceted, there are many risks both to mother and child that are increased in adolescent pregnancy. Many are unintended and are at risk for repeat adolescent pregnancy, especially within the first 2 years. Risks include but are not limited to: low birth weight, preterm delivery, stillbirth, and preeclampsia, as well as feelings of social isolation, delayed or neglected educational goals, and maternal depression.

    Discordant development of brain regions responsible for cognitive control and reward processing may render adolescents susceptible to risk taking. Identifying ways to reduce this neural imbalance during adolescence can have important implications for risk taking and associated health outcomes. Accordingly, we sought to examine how a key family relationship-family obligation-can reduce this vulnerability. Forty-eight adolescents underwent an fMRI scan during which they completed a risk-taking and cognitive control task. Results suggest that adolescents with greater family obligation values show decreased activation in the ventral striatum when receiving monetary rewards and increased dorsolateral PFC activation during behavioral inhibition. Reduced ventral striatum activation correlated with less real-life risk-taking behavior and enhanced dorsolateral PFC activation correlated with better decision-making skills. Thus, family obligation may decrease reward sensitivity and enhance cognitive control, thereby reducing risk-taking behaviors.

    Context: Dissociation is understood as maladaptive coping and is common in children and adolescents. Treatment outcome studies show improvement in comorbid conditions suggesting the need to implement programs that target dissociative pathology. Aim: To study the effect of practicing mindfulness among adolescents diagnosed with dissociative disorders. Settings and Design: It was a hospital-based repeated measures design. Materials and Methods: 7 adolescents participated in a mindfulness-based therapeutic program for 6 weeks. Statistical Analysis: Scores were expressed as mean ± standard deviation. Friedman test was used to assess significance of the difference in scores at various assessment phases. Wilcoxon signed rank test was used for post hoc analysis. Results: Participants were mostly female adolescents from rural, Eastern India. There was a significant reduction in dissociative experiences and significant improvement in mindfulness. Conclusions: Incorporating mindfulness in clinical practice may prove effective in reducing dissociation and promoting adaptive functioning. PMID:28066012

    Children and adolescents abusing drugs present a special challenge for our health system. Special risks for the development of drug dependence are psychic diseases of parents, familial addiction or multiply burdened families. The treatment of drug-addicted children and adolescents in child and youth psychiatry requires a highly individualised therapy programme as well as a pedagogic and therapeutic setting corresponding to age. 745 patients were examined in a retrospective study between 1998 and 2001. The results are shown below. 68% of the patients had a relevant psychiatric second diagnosis, 39 Patients of the examined drug addicted children and adolescents were diagnosed with an additional psychotic disturbance. A study of children and youth psychiatry clinics in the fall of 2001 showed that sufficient clinical care for drug-addicted children and adolescents is still lacking.

    This study investigated the roles of coping and masculinity in higher rates of depressive symptoms among adolescent girls, as compared to boys. A model was designed and tested through path analysis, which involved the variables of sex, gender, problem-focused coping, rumination, and distraction. The Reynolds Adolescent Depression Scale and the Bem Sex Role Inventory, as well as a measure of coping with general stressors was completed by 246 adolescents. Results showed that adolescent girls were more depressed than boys, and that girls used more emotion-focused and ruminative coping than did boys. Greater degrees of ruminative coping were related to high levels of depressive symptoms. Problem-focused and distractive coping were positively correlated with masculinity and negatively associated with depression. Surprisingly, girls were more likely to use problem-focused coping. Problem-focused and distractive coping were found to mediate the negative relationship between masculinity and depression.

    This study examined whether the development of sexualized media consumption and permissive sexual attitudes would be more strongly interrelated when adolescents perceived sexualized media images as highly realistic. We used data from a three-wave longitudinal sample of 444 Dutch adolescents aged 13-16 years at baseline. Results from parallel process latent growth modeling multigroup analyses showed that higher initial levels of sexualized media consumption were associated with higher initial level of permissive sexual attitudes. Moreover, increases of sexualized media consumption over time were associated with increases of permissive sexual attitudes over time. Considering the moderation by perceived realism, we found these effects only for those who perceived sexualized media as more realistic. Findings for male and female adolescents were similar except for the relations between initial levels and subsequent development. Among male adolescents who perceived sexualized media images to be realistic, higher initial levels of permissive sexual attitudes were related to subsequent less rapid development of sexualized media consumption. For male adolescents who perceived sexualized media to be less realistic, higher initial levels of sexualized media consumption were related to a subsequent less rapid development of permissive sexual attitudes. These relations were not found for female adolescents. Overall, our results suggest that, in male and female adolescents, those with a high level of perceived realism showed a correlated development of sexualized media consumption and permissive sexual attitudes. These findings point to a need for extended information on how to guide adolescents in interpreting and handling sexualized media in everyday life.

    Purpose Sleep disturbances are a common problem during adolescence. Often there is a relationship with the mental health of the affected person. The existing literature concerning the link between sleep disturbances and aggressive behavior and sleep disturbances and suicidality during adolescence shows no clear results. The present study tested a mediation model to prove the relation between sleep problems, aggressive behavior, and suicidality during adolescence. To take the link between suicidality and depression into account, the amount of depressive symptoms was included into the mediation model. Methods A sample of 93 adolescents aged 14–18 years (30% male) was studied. A survey was conducted to interview the adolescents about their mental health, sleep-related behaviors, aggressive behavior, and suicidality. Results Sleep problems and suicidality measures were significantly related to each other. Furthermore, aggressive behavior and suicidality showed a significant relationship. The expected link between sleep problems and aggressive behavior was not significant. For the mediation model, no significant influence of aggressive behavior on the relationship between the amount of sleep problems and suicidality was found. However, the impact of depressive symptoms on the relationship between sleep problems and suicidality was significant. Conclusion Sleep problems and overall suicidality in adolescents are significantly connected, even after adjusting for several possible influencing factors. Aggressive behavior could not be confirmed as a mediator for the association between sleep problems and suicidality in adolescents. Further studies to examine the link between insomnia symptoms, aggressive behavior, and suicidality in adolescents are necessary. PMID:25767409

    Background: Anthropometric measures are used as indicators of elevated blood pressure, but reported to have variable sensitivity among populations. This study was undertaken to identify the better indicator of Cardiac-risk factors by statistical comparison of BMI, Waist circumference, and Waist to Height (WtHr) ratio in apparently healthy adolescents and young adult female students of Tripura. Materials and Methods: A cross-sectional study was conducted in a resource limited setup on 210 apparently healthy female adolescents and young adult students in Tripura. Mean (±SD) of all parameters were compared (ANOVA) to recognize significant independent (anthropometric measures) and dependent factors (blood pressure indices and so on). Correlation (r) analysis was used to identify the better (p) indicator of blood pressure indices (dependent variable) and its impact was assessed by Multiple Regression analysis. Results: blood pressure indices are comparatively higher in obese and overweight participants with statistically significant (95.5% confidence) mean differences. Significant correlation with dependent factors is observed with BMI followed by WtHr and Waist Circumference. Impact of anthropometric measures with blood pressure Indices is most significant for BMI (P ≤ 0.020) followed by WtHr (P ≤ 0.500) and waist circumference (P ≤ 0.520). Conclusion: BMI is a superior indicator of blood pressure indices and can identify participants at risk even in apparently healthy adolescent and young adult females. PMID:27890980

    Oral contraceptive (OC) options for adolescents are provides. Clarification for those desiring a birth control method is necessary and the benefits of decreased acne and dysmenorrhea with low dose OCs should be stressed along with the importance of compliance. A community effort is suggested to communicate the sexual and contraceptive alternatives, including abstinence and outercourse (sexual stimulation to orgasm without intercourse). Attention is given to concerns associated with teenage sexual activity, prevention of adolescent pregnancy, contraceptive options for the adolescent patient, adolescent attitudes toward birth control OCs, management of the adolescent OC user, manipulation of steroid components of OCs to respond to adolescent concerns, and other hormonal contraceptive options such as minipills or abstinence. The text is supplemented with tables: the % of US women by single years of age for 1971, 1976, 1979, and 1982; comparative pregnancy and abortion rates for the US and 5 other countries; federal cost for teen childbearing; adolescent nonhormonal contraceptive methods (advantages, disadvantages, and retail cost); checklist to identify those at risk for noncompliance with OCs; hormonal side effects of OCs; risks from OCs to adolescents; and benefits of OCs. Concern about adolescent pregnancy dates back to Aristotle. A modern profile shows girls form single-parent families are sexually active at an earlier age, adolescent mothers produce offspring who repeat the cycle, victims of sexual abuse are more likely to be sexually active, and teenagers in foster care are 4 times more likely to be sexually active and 8 times more likely to become pregnant. Prevention involves a multifaceted approach. OCs are the most appropriate contraceptive choice for adolescents. Frequency of intercourse is closely associated with OC use after approximately 15 months of unprotected sexual activity. At risk for noncompliance variables are scales of personality development

    Objective: To study the influence of adolescence characteristics on asthma management. Methods: This was a qualitative study conducted in the city of Divinópolis, Minas Gerais, Southeast Brazil. Data were collected through semistructured interviews guided by a questionnaire with seven asthmatic adolescents followed-up in the primary public health care service of the city. Results: Using content analysis, three thematic categories were observed in the adolescents' responses: 1) family relationships in the treatment of asthma in adolescence; 2) the asthmatic adolescents and their peers; and 3) the role of the school for the asthmatic adolescents. Conclusions: The results demonstrated that peers, family, and school should be more valued by health professionals and by health care services when treating asthmatic adolescents, as these social relationships are closely associated with the adolescent and have an important role in asthma management. Attempts to meet the demands of adolescents contribute to improve asthma management. PMID:25479845

    The purpose of the present study was to investigate the relative importance of adolescents' attitude toward an act (the degree to which the person had a favorable or unfavorable evaluation or appraisal of the act's behavior in question), perceived norm, and perceived behavioral control in predicting Taiwanese adolescents' intention to purchase the merchandise of a celebrity when they had different levels of celebrity adoration. The present results showed that the relative strengths of attitude toward the act and the perception of behavioral control in predicting purchase intention toward the merchandise of a celebrity were stronger for adolescents in the celebrity adoration group than for adolescents in the celebrity nonadoration group. On the other hand, the relative importance of the perceived norm in predicting the attitude toward the act and the purchase intention was stronger for adolescents in the celebrity nonadoration group than for adolescents in the celebrity adoration group.

    The neurotoxic effects of methamphetamine (MA) exposure in the developing and adult brain can lead to behavioral alterations and cognitive deficits in adults. Previous increases in the rates of adolescent MA use necessitate that we understand the behavioral and cognitive effects of MA exposure during adolescence on the adolescent brain. Adolescents using MA exhibit high rates of nicotine (NIC) use, but the effects of concurrent MA and NIC in the adolescent brain have not been examined, and it is unknown if NIC mediates any of the effects of MA in the adolescent. In this study, the long-term effects of a neurotoxic dose of MA with or without NIC exposure during early adolescence (postnatal day 30-31) were examined later in adolescence (postnatal day 41-50) in male C57BL/6J mice. Effects on behavioral performance in the open field, Porsolt forced swim test, and conditioned place preference test, and cognitive performance in the novel object recognition test and Morris water maze were assessed. Additionally, the effects of MA and/or NIC on levels of microtubule associated-2 (MAP-2) protein in the nucleus accumbens and plasma corticosterone were examined. MA and NIC exposure during early adolescence separately decreased anxiety-like behavior in the open field test, which was not seen following co-administration of MA/NIC. There was no significant effect of early adolescent MA and/or NIC exposure on the intensity of MAP-2 immunoreactivity in the nucleus accumbens or on plasma corticosterone levels. These results show that early adolescent MA and NIC exposure separately decrease anxiety-like behavior in the open field, and that concurrent MA and NIC exposure does not induce the same behavioral change as either drug alone.

    Data from the national Teen Health and Technology Study of adolescents 13-18 years old (N = 5091) were used to examine online formation of romantic relationships. Results show that lesbian, gay, bisexual, transgender, and queer (LGBTQ) and non-LGBTQ adolescents similarly were most likely to have met their most recent boy/girlfriend in the past 12 months at school. However, they differed on many characteristics of romantic relationship initiation, including the extent to which they initiated romantic relationships online. LGBTQ and non-LGBTQ adolescents also differed on level of offline access to potential partners, offline popularity, and numerous other factors possibly related to online relationship initiation (e.g., Internet use and demographic factors). Even after adjusting for differences in these factors, LGBTQ adolescents were more likely than non-LGBTQ adolescents to find boy/girlfriends online in the past 12 months. The results support the rich-get-richer hypothesis as well as the social compensation hypothesis.

    We examined how African-American mothers' discussions with their adolescents about sex moderated the relationship between adolescents' sex-based discussions with their friends and adolescents' involvement in sexual behaviors. The 425 African-American adolescents were 12 through 15 years of age and had participated in an HIV prevention research project with their mothers. Linear and logistic regression analyses showed that, for girls, age, discussions with friends, and the interaction between mother and friend's sex-based discussions were statistically significant predictors of sexual behaviors. These findings suggest that the level of discussion with mothers had a moderating effect on the relationship between friends' discussions about sex and a girl's involvement in sexual behaviors. Although these results were not apparent for boys, there was a strong relationship between discussions with friends about sex and sexual behaviors among boys.

    Introduction Snacking is a complex behavior that may be influenced by entertainment media. Research suggests that snacking and unhealthy foods are commonly shown in programming that targets young audiences, but shows selected for study have been limited. We conducted a content analysis on shows that were named as favorites by adolescents to characterize portrayals of snacking on popular television. Methods A diverse sample of 2,130 adolescents (mean age, 14.3 y) listed 3 favorite television shows in a 2010 school-based survey. Three episodes each of the 25 most popular shows were coded for food-related content, including healthfulness, portion size, screen time use, setting, and social context. We also analyzed the characteristics of characters involved in eating incidents, the show type, and the show rating. We used χ2 tests, binomial tests, and multilevel regression models to compare incidence of snacks versus meals, the characteristics of those involved, and snacking across show characteristics. Results Almost half of food incidents on television shows were snacks. Snacks were significantly more likely than meals to be “mostly unhealthy” (69.3% vs 22.6%, P < .001) and were more likely to include screen time use (25.0% of snacking incidents vs 4.0% of meals, P < .001). Young characters and those coded as being of low socioeconomic status or overweight were overrepresented in snacking incidents. Sitcoms and shows rated for a youth audience were significantly more likely to portray snacking than were shows for adult audiences. Conclusion Media awareness and literacy programs should include foods and snacking behaviors among the issues they address. More healthful portrayals of food and dietary intake in entertainment shows’ content would create a healthier media environment for youth. PMID:27197079

    High adolescent fecundity principally affects developing countries. In spite of a decrease in the incidence of pregnancies in the developing countries over the past 13 years, the differences that exist with respect to developed countries turn adolescent fecundity into an indicator of the level of development of countries. The impact of adolescent pregnancy is evident in maternal and perinatal morbidity and mortality. Nonetheless, in addition to the age involved in precocious pregnancy, it also reflects previous conditions such as malnutrition, infectious diseases and deficiencies in the health care given to pregnant adolescents. The most important impact lies in the psychosocial area: it contributes to a loss of self-esteem, a destruction of life projects and the maintenance of the circle of poverty. This affects both adolescent mothers and fathers; the latter have been studied very little. Intervention with comprehensive health services and the maintenance of the education of adolescent mothers and fathers prevents repeat pregnancies. Evidence shows success in the prevention of the first pregnancy when the intervention includes comprehensive sexual education, the existence of preferential sexual and reproductive health services for adolescents, the handout of modern contraceptives gauged to the adolescence stage of the subjects and the existence of an information network. There is little research in contraception for adolescents, and for this reason, the indications given are projections of data obtained from adults.

  7. Stretched View Showing 'Victoria'

    [figure removed for brevity, see original site] Stretched View Showing 'Victoria'

    This pair of images from the panoramic camera on NASA's Mars Exploration Rover Opportunity served as initial confirmation that the two-year-old rover is within sight of 'Victoria Crater,' which it has been approaching for more than a year. Engineers on the rover team were unsure whether Opportunity would make it as far as Victoria, but scientists hoped for the chance to study such a large crater with their roving geologist. Victoria Crater is 800 meters (nearly half a mile) in diameter, about six times wider than 'Endurance Crater,' where Opportunity spent several months in 2004 examining rock layers affected by ancient water.

    When scientists using orbital data calculated that they should be able to detect Victoria's rim in rover images, they scrutinized frames taken in the direction of the crater by the panoramic camera. To positively characterize the subtle horizon profile of the crater and some of the features leading up to it, researchers created a vertically-stretched image (top) from a mosaic of regular frames from the panoramic camera (bottom), taken on Opportunity's 804th Martian day (April 29, 2006).

    The stretched image makes mild nearby dunes look like more threatening peaks, but that is only a result of the exaggerated vertical dimension. This vertical stretch technique was first applied to Viking Lander 2 panoramas by Philip Stooke, of the University of Western Ontario, Canada, to help locate the lander with respect to orbiter images. Vertically stretching the image allows features to be more readily identified by the Mars Exploration Rover science team.

    The bright white dot near the horizon to the right of center (barely visible without labeling or zoom-in) is thought to be a light-toned outcrop on the far wall of the crater, suggesting that the rover can see over the low rim of Victoria. In figure 1, the northeast and southeast rims are labeled

    Background There is accumulating evidence of alterations in neural circuitry underlying the processing of social-affective information in adolescent Major Depressive Disorder (MDD). However the extent to which such alterations are present in youth at risk for mood disorders remains unclear. Method Whole-brain blood oxygenation level-dependent task responses and functional connectivity using generalized psychophysiological interaction (gPPI) analyses to mild and intense happy face stimuli was examined in 29 adolescents with MDD (MDD; M age, 16.0, SD 1.2 years), 38 healthy adolescents at risk of a mood disorder, by virtue of having a parent diagnosed with either Bipolar Disorder (BD) or MDD (Mood-risk; M age 13.4, SD 2.5 years) and 43 healthy control adolescents, having parents with no psychiatric disorder (HC; M age 14.6, SD 2.2 years). Results Relative to HC adolescents, Mood-risk adolescents showed elevated right dorsolateral prefrontal cortex (DLPFC) activation to 100% intensity happy (vs. neutral) faces and concomitant lowered ventral putamen activity to 50% intensity happy (vs. neutral) faces. gPPI analyses revealed that MDD adolescents showed significantly lower right DLPFC functional connectivity with the ventrolateral PFC (VLPFC) compared to HC to all happy faces. Limitations The current study is limited by the smaller number of healthy offspring at risk for MDD compared to BD. Conclusions Because Mood-risk adolescents were healthy at the time of the scan, elevated DLPFC and lowered ventral striatal activity in Mood-risk adolescents may be associated with risk or resiliency. In contrast, altered DLPFC-VLPFC functional connectivity in MDD adolescents may be associated with depressed mood state. Such alterations may affect social-affective development and progression to a mood disorder in Mood-risk adolescents. Future longitudinal follow-up studies are needed to directly answer this research question. PMID:26724693

    Acculturation plays a critical role in the adjustment of Asian Americans, as a large proportion of them are immigrants in the US. However, little is known about how acculturation influences Asian American adolescents' academic trajectories over time. Using a longitudinal sample of 444 Chinese American families (54% female children), the current study explored the effect of mothers', fathers', and adolescents' individual acculturation profiles and parent-child acculturation dissonance on adolescents' academic trajectories from 8th to 12th grade. Academic performance was measured by grade point average (GPA), and by standardized test scores in English language arts (ELA) and Math every year. Latent growth modeling analyses showed that adolescents with a Chinese-oriented father showed faster decline in GPA, and Chinese-oriented adolescents had lower initial ELA scores. Adolescents whose parents had American-oriented acculturation profiles tended to have lower initial Math scores. These results suggest that Chinese and American profiles may be disadvantageous for certain aspects of academic performance, and bicultural adolescents and/or adolescents with bicultural parents are best positioned to achieve across multiple domains. In terms of the role of parent-child acculturation dissonance on academic trajectories, the current study highlighted the importance of distinguishing among different types of dissonance. Adolescents who were more Chinese-oriented than their parents tended to have the lowest initial ELA scores, and adolescents experiencing more normative acculturation dissonance (i.e., who were more American-oriented than their parents) had the highest initial ELA scores. No effects of parent-child acculturation dissonance were observed for GPAs or standardized Math scores. Altogether, the current findings add nuances to the current understanding of acculturation and adolescent adjustment.

  10. Adolescent fertility: worldwide concerns.

    1985-04-01

    There is growing concern over the adverse health, social, economic, and demographic effects of adolescent fertility. Morbidity and mortality rates ar significantly higher for teenage mothers and their infants, and early initiation of childbearing generally means truncated education, lower future family income, and larger completed family size. Adolescent fertility rates, which largely reflect marriage patterns, range from 4/1000 in Mauritania; in sub-Saharan Africa, virtually all rates are over 100. In most countries, adolescent fertility rates are declining due to rising age at marriage, increased educational and economic opportunities for young women, changes in social customs, increased use of contraception, and access to abortion. However, even if fertility rates were to decline dramatically among adolescent women in developing countries, their sheer numbers imply that their fertility will have a major impact on world population growth in the years ahead. The number of women in the world ages 15-19 years is expected to increase from 245 million in 1985 to over 320 million in the years 2020; 82% of these women live in developing countries. As a result of more and earlier premarital sexual activity, fostered by the lengthening gap between puberty and marriage, diminished parental and social controls, and increasing peer and media pressure to be sexually active, abortion and out-of-wedlock childbearing are increasing among teenagers in many developed and rapidly urbanizing developing countries. Laws and policies regarding sex education in the schools and access to family planning services by adolescents can either inhibit or support efforts to reduce adolescent fertility. Since contraceptive use is often sporadic and ineffective among adolescents, family planning services are crucial. Such programs should aim to reduce adolescents' dependence on abortion through preventive measures and increase awareness of the benefits of delayed sexual activity. Similarly, sex

  11. Iron nutrition in adolescence.

    Mesías, Marta; Seiquer, Isabel; Navarro, M Pilar

    2013-01-01

    Adolescence is an important period of nutritional vulnerability due to increased dietary requirements for growth and development. Iron needs are elevated as a result of intensive growth and muscular development, which implies an increase in blood volume; thus, it is extremely important for the adolescent's iron requirements to be met. Diet, therefore, must provide enough iron and, moreover, nutrients producing adequate iron bioavailability to favor element utilization and thus be sufficient for needs at this stage of life. Currently, many adolescents consume monotonous and unbalanced diets which may limit mineral intake and/or bioavailability, leading to iron deficiency and, consequently, to ferropenic anemia, a nutritional deficit of worldwide prevalence. Iron deficiency, apart from provoking important physiological repercussions, can adversely affect adolescents' cognitive ability and behavior. Accordingly, promoting the consumption of a varied, adjusted, and balanced diet by adolescents will facilitate iron utilization, benefiting their health both at present and in adulthood. This review discusses how physiological changes during adolescence can cause iron requirements to increase. Consequently, it is important that diet should contribute an appropriate amount of this mineral and, moreover, with an adequate bioavailability to satisfy needs during this special period of life.

    The success of childhood vaccination against hepatitis B relies on persistence of immunity into adolescence and adulthood. In 2000, two hexavalent vaccines with a hepatitis B component (Hexavac, Infanrix hexa) were introduced in Germany. Hexavac was withdrawn in 2005 amidst concerns about its long-term hepatitis B protection. We compared hepatitis B surface antibody (anti-HBs) levels in children fully vaccinated with Hexavac or Infanrix hexa (n=477) in a secondary data analysis of a large cross-sectional health survey in Germany. On average 2.4 years after vaccination, 25.3% of Hexavac vaccinees had anti-HBs levels <10 mIU/ml (95% CI 19.0-32.8) compared to 4.7% of Infanrix hexa vaccinees (95% CI 2.4-8.9). These findings suggest that short-term hepatitis B immunogenicity in Hexavac vaccinees may also be weaker. Further studies are warranted to assess whether Hexavac vaccinees should be re-vaccinated or receive a booster vaccination before these birth cohorts reach adolescence.

    Several studies have shown that risky driving is especially prevalent among young drivers and recent research has pointed out that driving in adolescence should be investigated in the more general context of adolescent development. The first aim of this contribution was to analyze involvement in risky driving in a normative sample of 645 Italian adolescents, boys and girls, aged 14-17, through a self-report questionnaire. A second aim was to evaluate the association between risky driving and lifestyle, defined as involvement in other health risk behaviors and leisure activities. The main results showed that many adolescents drove cars and motorcycles without the required driving license and the most frequent offences were speeding and failure to maintain a safe braking distance. Gender and age differences were also investigated. Results concerning the association between risky driving and lifestyle showed that risky driving was not an isolated behavior. Boys who displayed risky driving practices were more likely to adopt a lifestyle characterized by high involvement in antisocial behaviors, tobacco smoking, comfort eating and time spent in non-organized activities with friends. Girls involved in risky driving were more likely to be involved in other risk-taking behaviors, antisocial behaviors and drug use.

    The purpose of this secondary analysis of data is to examine relationships among Asian American Pacific Islanders (AAPI) adolescents' level of acculturation, maternal influences, and age of sexual initiation. Selected predictive variables are based on the theoretical frameworks and literature review. The results indicate that for these adolescents speaking English at home was positively associated with maternal sexual discussion, mothers' perceptions of connectedness with their adolescents, adolescents' perceived maternal sexual expectations, and later sexual initiation at Wave 1. Adolescents' years of U.S. residency are positively associated with adolescents' level of perceived connectedness with their mothers and later sexual initiation at Wave 2. Adolescents' level of acculturation influence how they interacted with their mothers, perceived their mothers' sexual expectations, and when they decided to initiate sexual intercourse. Interventions to delay AAPI adolescents' sexual debut should consider factors related to AAPI adolescents' and their mothers' levels of acculturation.

    Gambling has become one of the most frequently reported addictive behaviors among young people. Understanding risk factors associated with the onset or maintenance of gambling problems in adolescence has implications for its prevention and treatment. The main aim of the present study was to examine the potential relationships between impulsivity and problem gambling in adolescence. Participants were 874 high school students (average age: 15 years old) who were surveyed to provide data on gambling and impulsivity. Self-reported gambling behavior was assessed using the South Oaks Gambling Screen – Revised for Adolescents (SOGS-RA) and impulsivity was measured using the Impulsive Sensation Seeking Questionnaire (ZKPQ), the Barratt Impulsiveness Scale (BIS-11-A), and a delay discounting task. The data were analyzed using both a prospective-longitudinal and a cross-sectional design. In the longitudinal analyses, results showed that the impulsivity subscale of the ZKPQ increased the risk of problem gambling (p = 0.003). In the cross-sectional analyses, all the impulsivity measures were higher in at-risk/problem gamblers than in non-problem gamblers (p = 0.04; 0.03; and 0.01, respectively). These findings further support the relationship between impulsivity and gambling in adolescence. Moreover, our findings suggest a bidirectional relationship between impulsivity and problem gambling in adolescence. These results have consequences for the development of prevention and treatment programs for adolescents with gambling problems. PMID:28008322

    Relationships influence sexual risk and maternal-child health. Few studies have assessed relationship dissolution and its association with sexually transmitted diseases (STD) among adolescent parents. Our study aimed to describe relationship dissolution among 295 parenting and non-parenting adolescents over an 18-month period and how it related to STD incidence. Results showed that nonparenting adolescents in a relationship with someone other than their baby's father were more likely to have a relationship dissolution over an 18-month period compared to those in a relationship with the baby's father (OR = 1.69, P < .05). Parenting adolescents who ended their relationship with their baby's father were 3 times more likely to get an STD over the course of the study compared to parenting adolescents who remained with their baby's father (39% vs. 13%). Comparatively, nonparenting adolescents who ended their relationship were only 1.4 times more likely to get an STD compared to non-parenting adolescents who remained with their partner (44% vs. 32%). Our results suggest that prevention programs that incorporate male partners and components that strengthen relationship skills may reduce HIV/STD risk and help adolescents adapt during times of transition such as parenthood.

    Several studies have investigated how prepared adolescents are to transition to adult health care and barriers to transition for adolescents with special health care needs. The majority of these studies, however, have only assessed these experiences from the parents' point of view. Our study aims to assess the congruence of adolescents and parents reported transition planning and the factors associated with planning. A secondary data analysis was conducted using telephone survey data. Data were collected from parents and adolescents with special health care needs who received health care through Florida's Title V public insurance program. The final sample included 376 matched pairs of adolescent-parent surveys. To assess health care transition planning, respondents were asked if discussions had occurred with the adolescents' doctor, nurse, or with each other. Parents reported higher levels of planning than adolescents. Results show the lowest level of agreement between the parent and adolescent reports (κ < 0.2) and the highest level of agreement when parents and adolescents were asked if they discussed transition with each other (κ = 0.19). Regression results suggest that older adolescents are more prepared (vs. younger) and that adolescents whose parents have lower educational attainment are less prepared for transition. Results from this study suggest that there may be miscommunication around discussions related to transition, although further research is warranted. It is important to ensure that adolescents, not just parents, have a thorough understanding of transition since they will ultimately be responsible for their own health care once they reach adulthood.

    2008-02-01

    This study tests the hypothesis that self-regulation serves as a resiliency factor in buffering youth from negative influences of peer deviance in middle to late adolescence. The interactive effects between peer deviance and self-regulation were investigated on change in antisocial behavior from age 17 to 19 years in an ethnically diverse sample of adolescents. A multi-agent construct was created using adolescent, parent, and teacher reports of self-regulation and peer deviance. Results indicated that self-regulation shows convergent validity and covaries as expected with developmental patterns of adolescent antisocial behavior. Self-regulation moderated the association of peer deviance with later self-reported adolescent antisocial behavior after controlling for prior levels of antisocial behavior. The implications of these findings for models for the development of antisocial behaviors and for intervention science are discussed.

Risks of developing specific mental disorders were calculated. African migrant children and adolescents showed higher risk in traumatic stress and adjustment disorders (F 43 in ICD-10), the Asiatic group in dissociative disorders (F 44-45). Compared to other European migrants the German children and adolescents without migration background had a higher risk of affective disorders (F 3). Adolescents (N = 3,556) with Russian and Polish background had a higher risk of disorders induced by psychotropic substances (F 1). Turkish and Arabic adolescents had a 4- to 5-times increasing risk in schizophrenia as well as schizotypal or delusional disorders (F 2). In addition, mental disorders were influenced by gender and nationality. These study results suggest that a different vulnerability to specific mental disorders is associated to ethnicity.

    Research has repeatedly shown that neighbourhood disadvantage negatively influences individual educational outcomes. However, the great variation in outcomes indicates substantial unobserved heterogeneity. Looking at the rates of obtaining a basic educational qualification, the hypothesis is that individual traits of adolescents can buffer neighbourhood effects. First, adolescents with a more resilient personality may be better able to cope with neighbourhood adversity. And second, educational commitments might buffer adolescents from negative neighbourhood influences. These hypotheses are tested employing survival analysis, using six wave panel data, containing information on ten years of adolescents' lives. The results show that resilients experience no negative influence of neighbourhood disadvantage, while both undercontrollers and overcontrollers do. And, the stronger adolescents' educational commitments, the less they experience the negative effect of neighbourhood adversity. In sum, neighbourhood effects are found, but not for everybody.

    This study examined associations of peer socialization and selection, over time, with nonsuicidal self-injury (NSSI) among 5,787 (54.2 % females) Chinese community adolescents. Both effects were tested using two aspects of adolescents' friendship networks: the best friend and the friendship group. Participants completed questionnaires assessing NSSI, depressive symptoms and maladaptive impulsive behaviors at two waves of time over a 6-month period. Results showed that even after controlling for the effects of depressive symptoms and maladaptive impulsive behaviors, the best friends' engagement in NSSI still significantly predicted adolescents' own engagement in NSSI. Adolescents' friendship groups' NSSI status also significantly predicted their own NSSI status and frequency. Additionally, adolescents with NSSI tended to join peer groups with other members also engaging in NSSI.

    This brief report describes dating violence victimization among adolescents in Flanders, Belgium, and focuses on how dating violence is related to adolescents' well-being and engagement in risk behaviors, such as substance use, sexual behaviors, and engagement in vandalism or fighting. A survey was conducted in Flanders, Belgium among 1187 adolescents (61.3% female, n = 728). A total of 466 respondents between 16 and 22 years old (M = 17.82 years, SD = 0.92) were in a relationship (71.0% female, n = 331), and, therefore, formed the subsample of the present study. The results show that adolescents, who consume alcohol at a younger age, have ever used marihuana, or were involved in vandalism have a higher probability to become victim of dating violence than adolescents who are not involved in these behaviors. Dating violence victimization was also linked with symptoms of depression and a lower self-esteem.

    The first follow-up of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS Wave 1) was conducted from 2009 to 2012 as a combined cross-sectional and longitudinal study and provides, among other things, data on allergic diseases. Data collection was carried out by telephone interviews. In total, 6,093 girls and 6,275 boys were included, among them 4,455 newly recruited 0- to 6-year-olds (response 38.8%) and 7,913 KiGGS follow-up participants aged 7-17 years (response 72.9%). Based on parent reports, 15.6% (95% confidence interval 14.7-16.5) of children and adolescents aged 0-17 years were currently affected by at least one atopic disease. The 12-month prevalence rates of hay fever, atopic dermatitis, and asthma were 9.1% (8.4-9.8), 6.0% (5.4-6.6), and 4.1% (3.6-4.6), respectively. In all, 2.2% (1.9-2.6) of the children and adolescents were currently suffering from contact dermatitis. Compared with the baseline KiGGS survey from 2003 to 2006, a higher percentage of participants reported the occurrence of asthma within the past 12 months in the recent KiGGS Wave 1 (4.1 vs. 3.2%; p = 0.0034). The total increase is mainly due to higher prevalence rates among 0- to 6-year-olds, especially in girls. Higher 12-month prevalence rates can be also observed for hay fever among 0- to 6-year-olds, especially in girls, although the total increase is not statistically significant (9.1 vs. 8.3%; p = 0.08). There was a declining trend for atopic dermatitis: 6.8% (2003-2006) vs. 5.4% (2009-2012); p = 0.0015.

    Background The aims of this study were to assess the prevalence of a comorbid Attention Deficit Hyperactivity Disorder (ADHD) diagnosis in Borderline Personality Disorder (BPD), and its impact on the clinical presentation of BPD in adolescents, and to determine which type of impulsivity specifically characterizes adolescents with BPD-ADHD. Methods ADHD diagnoses were sought in a sample of 85 DSM-IV BPD adolescents drawn from the EURNET BPD. Axis-I and -II disorders were determined with the K-SADS-PL and the SIDP-IV, respectively. Impulsivity was assessed with the BIS-11. Results 11% (N = 9) of BPD participants had a current ADHD diagnosis. BPD-ADHD adolescents showed higher prevalence of Disruptive disorders (Chi2 = 9.09, p = 0.01) and a non-significant trend for a higher prevalence of other cluster B personality disorders (Chi2 = 2.70, p = 0.08). Regression analyses revealed a significant association between Attentional/Cognitive impulsivity scores and ADHD (Wald Z = 6.69; p = 0.01; Exp(B) = 2.02, CI 95% 1.19-3.45). Conclusions Comorbid ADHD influences the clinical presentation of adolescents with BPD and is associated with higher rates of disruptive disorders, with a trend towards a greater likelihood of cluster B personality disorders and with higher levels of impulsivity, especially of the attentional/cognitive type. A subgroup of BPD patients may exhibit developmentally driven impairments of the inhibitory system persisting since childhood. Specific interventions should be recommended for this subsample of BPD adolescents. PMID:21961882

    We investigated whether adolescent male rats show less habituation of corticosterone release than adult male rats to acute vs repeated (16) daily one hour episodes of isolation stress, as well as the role of partner familiarity during recovery on social behavior, plasma corticosterone, and Zif268 expression in brain regions. Adolescents spent more time in social contact than did adults during the initial days of the repeated stress procedures, but both adolescents and adults that returned to an unfamiliar peer after isolation had higher social activity than rats returned to a familiar peer (p=0.002) or undisturbed control rats (p<0.001). Both ages showed evidence of habituation, with reduced corticosterone response to repeated than acute isolation (p=0.01). Adolescents, however, showed sensitized corticosterone release to repeated compared with an acute pairing with an unfamiliar peer during recovery (p=0.03), a difference not found in adults. Consistent with habituation of corticosterone release, the repeated isolation groups had lower Zif268 immunoreactive cell counts in the paraventricular nucleus (p<0.001) and in the arcuate nucleus (p=0.002) than did the acute groups, and adolescents had higher Zif268 immunoreactive cell counts in the paraventricular nucleus than did adults during the recovery period (p<0.001), irrespective of stress history and partner familiarity. Partner familiarity had only modest effects on Zif268 immunoreactivity, and experimental effects on plasma testosterone concentrations were only in adults. The results highlight social and endocrine factors that may underlie the greater vulnerability of the adolescent period of development.

    The authors of the preceding articles raise legitimate questions about patient and staff rights and the unintended consequences of allowing ABC News to film inside teaching hospitals. We explain why we regard their fears as baseless and not supported by what we heard from individuals portrayed in the filming, our decade-long experience making medical documentaries, and the full un-aired context of the scenes shown in the broadcast. The authors don't and can't know what conversations we had, what documents we reviewed, and what protections we put in place in each televised scene. Finally, we hope to correct several misleading examples cited by the authors as well as their offhand mischaracterization of our program as a "reality" show.

    Isomorphism, or parallel process, occurs in family therapy when patterns of therapist-client interaction replicate problematic interaction patterns within the family. This study investigated parallel demand-withdraw processes in Brief Strategic Family Therapy (BSFT) for adolescent drug abuse, hypothesizing that therapist-demand/adolescent-withdraw interaction (TD/AW) cycles observed early in treatment would predict poor adolescent outcomes at follow-up for families who exhibited entrenched parent-demand/adolescent-withdraw interaction (PD/AW) before treatment began. Participants were 91 families who received at least 4 sessions of BSFT in a multi-site clinical trial on adolescent drug abuse (Robbins et al., 2011). Prior to receiving therapy, families completed videotaped family interaction tasks from which trained observers coded PD/AW. Another team of raters coded TD/AW during two early BSFT sessions. The main dependent variable was the number of drug use days that adolescents reported in Timeline Follow-Back interviews 7 to 12 months after family therapy began. Zero-inflated Poisson (ZIP) regression analyses supported the main hypothesis, showing that PD/AW and TD/AW interacted to predict adolescent drug use at follow-up. For adolescents in high PD/AW families, higher levels of TD/AW predicted significant increases in drug use at follow-up, whereas for low PD/AW families, TD/AW and follow-up drug use were unrelated. Results suggest that attending to parallel demand-withdraw processes in parent/adolescent and therapist/adolescent dyads may be useful in family therapy for substance-using adolescents.

    HIGHLIGHTS This study tested the effects of adolescent-stress on adult learning and memory.Adolescent-stressed rats had enhanced reversal learning compared to unstressed rats.Adolescent-stress exposure made working memory more vulnerable to disturbance.Adolescent-stress did not affect adult associative learning or reference memory. Exposure to acute stress can cause a myriad of cognitive impairments, but whether negative experiences continue to hinder individual as they age is not as well understood. We determined how chronic unpredictable stress during adolescence affects multiple learning and memory processes in adulthood. Using male Sprague Dawley rats, we measured learning (both associative and reversal) and memory (both reference and working) starting 110 days after completion of an adolescent-stress treatment. We found that adolescent-stress affected adult cognitive abilities in a context-dependent way. Compared to rats reared without stress, adolescent-stressed rats exhibited enhanced reversal learning, an indicator of behavioral flexibility, but showed no change in associative learning and reference memory abilities. Working memory, which in humans is thought to underpin reasoning, mathematical skills, and reading comprehension, may be enhanced by exposure to adolescent-stress. However, when adolescent-stressed animals were tested after a novel disturbance, they exhibited a 5-fold decrease in working memory performance while unstressed rats continued to exhibit a linear learning curve. These results emphasize the capacity for stress during adolescence to transform the cognitive abilities of adult animals, even after stress exposure has ceased and animals have resided in safe environments for the majority of their lifespans.

    Background Child and adolescent obesity predisposes individuals to an increased risk of morbidity and mortality from a range of lifestyle diseases. Although there is some evidence to suggest that rates of pediatric obesity have leveled off in recent years, this has not been the case among youth from low socioeconomic backgrounds. The purpose of this paper is to report the rationale, study design and baseline findings of a school-based obesity prevention program for low-active adolescent girls from disadvantaged secondary schools. Methods/Design The Nutrition and Enjoyable Activity for Teen Girls (NEAT Girls) intervention will be evaluated using a group randomized controlled trial. NEAT Girls is a 12-month multi-component school-based intervention developed in reference to Social Cognitive Theory and includes enhanced school sport sessions, interactive seminars, nutrition workshops, lunch-time physical activity (PA) sessions, PA and nutrition handbooks, parent newsletters, pedometers for self-monitoring and text messaging for social support. The following variables were assessed at baseline and will be completed again at 12- and 24-months: adiposity, objectively measured PA, muscular fitness, time spent in sedentary behaviors, dietary intake, PA and nutrition social-cognitive mediators, physical self-perception and global self-esteem. Statistical analyses will follow intention-to-treat principles and hypothesized mediators of PA and nutrition behavior change will be explored. Discussion NEAT Girls is an innovative intervention targeting low-active girls using evidence-based behavior change strategies and nutrition and PA messages and has the potential to prevent unhealthy weight gain and reduce the decline in physical activity and poor dietary habits associated with low socio-economic status. Few studies have reported the long-term effects of school-based obesity prevention programs and the current study has the potential to make an important contribution to the

    This study aims to examine whether (a) low child valence (emotional connectedness) within the mother-child relationship increases the risk for offspring depression, (b) low child potency (individual autonomy) increases the risk for offspring anxiety, and (c) maternal psychopathology pronounces these associations. We used data from a prospective-longitudinal study of adolescents (aged 14-17 at baseline) and their mothers (N = 1,015 mother-child dyads). Anxiety disorders and depression were assessed repeatedly over 10 years in adolescents (T0, T1, T2, T3) and their mothers (T1, T3) using the DSM-IV/M-CIDI. Valence and potency were assessed in mothers (T1) with the Subjective Family Image Questionnaire. Odds ratios (OR) from logistic regression were used to estimate associations between low child valence/potency and offspring psychopathology (cumulated lifetime incidences; adjusted for sex and age). In separate models (low valence or low potency as predictor), low child valence predicted offspring depression only (OR = 1.26 per SD), while low child potency predicted offspring anxiety (OR = 1.24) and depression (OR = 1.24). In multiple models (low valence and low potency as predictors), low child valence predicted offspring depression only (OR = 1.19), while low child potency predicted offspring anxiety only (OR = 1.22). Low child potency interacted with maternal anxiety on predicting offspring depression (OR = 1.49), i.e. low child potency predicted offspring depression only in the presence of maternal anxiety (OR = 1.33). These findings suggest that low child valence increases the risk for offspring depression, while low child potency increases the risk for offspring anxiety and depression and interacts with maternal psychopathology on predicting offspring depression.

    Validation-study data were analysed to investigate retention interval (RI) and prompt effects on the accuracy of fourth-grade children's reports of school-breakfast and school-lunch (in 24-h recalls), and the accuracy of school-breakfast reports by breakfast location (classroom; cafeteria). Randomly selected fourth-grade children at ten schools in four districts were observed eating school-provided breakfast and lunch, and were interviewed under one of eight conditions created by crossing two RIs ('short'--prior-24-hour recall obtained in the afternoon and 'long'--previous-day recall obtained in the morning) with four prompts ('forward'--distant to recent, 'meal name'--breakfast, etc., 'open'--no instructions, and 'reverse'--recent to distant). Each condition had sixty children (half were girls). Of 480 children, 355 and 409 reported meals satisfying criteria for reports of school-breakfast and school-lunch, respectively. For breakfast and lunch separately, a conventional measure--report rate--and reporting-error-sensitive measures--correspondence rate and inflation ratio--were calculated for energy per meal-reporting child. Correspondence rate and inflation ratio--but not report rate--showed better accuracy for school-breakfast and school-lunch reports with the short RI than with the long RI; this pattern was not found for some prompts for each sex. Correspondence rate and inflation ratio showed better school-breakfast report accuracy for the classroom than for cafeteria location for each prompt, but report rate showed the opposite. For each RI, correspondence rate and inflation ratio showed better accuracy for lunch than for breakfast, but report rate showed the opposite. When choosing RI and prompts for recalls, researchers and practitioners should select a short RI to maximise accuracy. Recommendations for prompt selections are less clear. As report rates distort validation-study accuracy conclusions, reporting-error-sensitive measures are recommended.

  9. Antidepressants and the adolescent brain.

    Major unipolar depression is a significant global health problem, with the highest incident risk being during adolescence. A depressive illness during this period is associated with negative long-term consequences including suicide, additional psychiatric comorbidity, interpersonal relationship problems, poor educational performance and poor employment attainment well into adult life. Despite previous safety concerns, selective serotonin reuptake inhibitors (SSRIs) remain a key component of the treatment of moderate to severe depression episodes in adolescents. The impact of SSRIs on the developing adolescent brain, however, remains unclear. In this review we first consider what is currently known about the developing brain during adolescence and how these development processes may be affected by a depressive illness. We then review our understanding of the action of SSRIs, their effects on the brain and how these may differ between adults and adolescents. We conclude that there is currently little evidence to indicate that the human adolescent brain is at developmental risk from SSRIs. Furthermore, there is no clear-cut evidence to support the concerns of marked suicidal adverse side effects accruing in depressed adolescents being treated with SSRIs. Neither, however, is there irrefutable evidence to dismiss all such concerns. This makes SSRI prescribing a matter of medical judgement, ensuring the benefits outweigh the risks for the individual patients, as with so much in therapeutics. Overall, SSRIs show clinical benefits that we judge to outweigh the risks to neurodevelopment and are an important therapeutic choice in the treatment of moderate to severe adolescent depression.

    Fundamental changes in brain structure and function during adolescence are well-characterized, but the extent to which experience modulates adolescent neurodevelopment is not. Musical experience provides an ideal case for examining this question because the influence of music training begun early in life is well-known. We investigated the effects of in-school music training, previously shown to enhance auditory skills, versus another in-school training program that did not focus on development of auditory skills (active control). We tested adolescents on neural responses to sound and language skills before they entered high school (pretraining) and again 3 y later. Here, we show that in-school music training begun in high school prolongs the stability of subcortical sound processing and accelerates maturation of cortical auditory responses. Although phonological processing improved in both the music training and active control groups, the enhancement was greater in adolescents who underwent music training. Thus, music training initiated as late as adolescence can enhance neural processing of sound and confer benefits for language skills. These results establish the potential for experience-driven brain plasticity during adolescence and demonstrate that in-school programs can engender these changes. PMID:26195739

    Background We report the lifetime and 12-month prevalence and associations of mental health treatment among Mexican adolescents with suicide-related outcomes (SROs; including ideation, plans, gestures and attempts). Methods A representative multistage probability household survey of 3005 adolescents aged 12 to 17 years residing in the Mexico City Metropolitan Area was carried out in 2005. Discrete time survival analyses were used to assess the relationships between SROs and receiving treatment for emotional, alcohol, or drug problems. Results The prevalence of lifetime service use among respondents with SROs was 35% for those with ideation only, 44% for those with ideation and plan, 49% for those with gesture and 50% for those with attempt; the prevalence of 12-month service use was 10%, 24%, 6% and 21%, respectively. Timing between onset of SRO and receiving treatment for emotional, alcohol, or drug problems showed that about 50% of adolescents will have contact with a service provider before developing any SRO. Healthcare professionals were the most likely to be consulted, followed by school-based programs. Limitations This survey was limited to adolescents living in one of the largest metropolitan areas in the world and the analyses used data on retrospectively reported ages of onset that are subject to recall errors. Conclusions Most suicidal adolescents do not receive treatment, and many adolescents develop their suicidality in spite of prior contacts with service providers. Interventions to increase treatment, prevention, and monitoring are sorely needed for this vulnerable population. PMID:19411113

    2016-11-01

    Adolescents are known to be an at-risk population for developing Internet gaming disorder (IGD). A recent clinical model has proposed that adolescents with IGD may endorse a unique set of maladaptive beliefs that underlie persistent and excessive involvement in Internet gaming activities. These include (a) beliefs about game reward value and tangibility, (b) maladaptive and inflexible rules about gaming behaviour, (c) over-reliance on gaming to meet self-esteem needs, and (d) gaming as a method of gaining social acceptance. A sample of 824 adolescents (402 male and 422 female) were recruited from multiple secondary schools and administered a survey that included measures of IGD symptomatology, problematic Internet gaming cognition, and psychological distress. The results showed that adolescents with IGD report significantly more maladaptive gaming beliefs than adolescents without IGD, including those who play Internet games for more than 30 h per week. The size of observed effects were large. The strong association between gaming cognitions and IGD symptoms still held after controlling for measures of gaming activity and psychological distress. These findings indicate that adolescents with IGD have distinct problematic thoughts about gaming, and highlight the importance of addressing these cognitions in therapeutic interventions for the disorder.

    The study examines the impact of body image in adolescents' well-being. Well-being was assessed with the scale Kidscreen10, with the Cantril ladder for satisfaction with life and with an ad hoc happiness scale. The study presents data on adolescent health from the Health Behavior in School-aged Children (HBSC)/World Health Organization study in Portugal (2006), with a sample of 4,877 adolescents, average age of 14 years old and gender distribution at 49,6% males. Portuguese adolescents showed differences between gender and age group regarding their body image-related satisfaction/dissatisfaction and self-perceived body image, being that both components have a direct impact on the levels of well-being. The male gender has better results in the perception of body image and, consequently, well-being. The largest inter-gender differences for well-being is at 15 years of age. The main predictors of well-being are the look and body satisfaction/dissatisfaction, with greater importance on the affective component. This research highlights the importance of body image for adolescents' well-being, as well as to prepare educational strategies adapted to adolescents' age and gender, by helping them to develop skills concerning self-knowledge and caring for their look.

    Stressful experiences during adolescence can alter the trajectory of neural development and contribute to psychiatric disorders in adulthood. We previously demonstrated that adolescent male rats exposed to repeated social defeat stress show changes in mesocorticolimbic dopamine content both at baseline and in response to amphetamine when tested in adulthood. In the present study we examined whether markers of adult dopamine function are also compromised by adolescent experience of social defeat. Given that the dopamine transporter as well as dopamine D1 receptors act as regulators of psychostimulant action, are stress sensitive and undergo changes during adolescence, quantitative autoradiography was used to measure [(3)H]-GBR12935 binding to the dopamine transporter and [(3)H]-SCH23390 binding to dopamine D1 receptors, respectively. Our results indicate that social defeat during adolescence led to higher dopamine transporter binding in the infralimbic region of the medial prefrontal cortex and higher dopamine D1 receptor binding in the caudate putamen, while other brain regions analyzed were comparable to controls. Thus it appears that social defeat during adolescence causes specific changes to the adult dopamine system, which may contribute to behavioral alterations and increased drug seeking.

    Objective Neural network models that guide neuropsychological assessment practices are increasingly used to explicate depression, though a paucity of work has focused on regulatory systems that are under development in adolescence. The purpose of this study was to evaluate subsystems of attention related to executive functioning including alerting, orienting, and executive attention networks, as well as sustained attention with varying working memory load, in a sample of depressed and well adolescents. Method Neuropsychological functioning in 99 adolescents diagnosed with major depressive disorder (MDD) and 63 adolescent healthy controls (M = 16.6 years old) was assessed on the Attention Network Task (ANT) and the Continuous Performance Test, Identical Pairs (CPT). Results Adolescents with MDD, particularly those who were not medicated, were slower to process conflict (slower reaction time on the executive attention scale of the ANT) compared to controls, particularly for those who were not undergoing psychopharmacological treatment. Tentative evidence also suggests that within the MDD group, orienting performance was more impaired in those with a history of comorbid substance use disorder, and alerting was more impaired in those with a history of a suicide attempt. Conclusions Adolescents with depression showed impaired executive attention, although cognitive performance varied across subgroups of patients. These findings highlight the importance of examining neurocognitive correlates associated with features of depression and suggest an avenue for future research to help guide the development of interventions.

    2012-04-01

    Research on the correspondence between adolescent and parent reports of adolescent substance abuse has typically been conducted on adolescent outpatient treatment samples, or on non-treatment samples. In the current study, fifty adolescents receiving residential substance abuse treatment, and their parents were assessed separately regarding the teen's substance use (e.g., cigarettes, alcohol, marijuana, other illicit drugs) during the 90 days preceding adolescent treatment entry. Correspondence between reporters was for the most part fair to excellent, with observed discrepancies generally due to parents providing lower estimates of use than did adolescents. Multiple regression analysis revealed that higher discrepancy between reporters occurred when the parent was younger, when the parent encountered fewer problems due to the teen's substance use, when the adolescent attended more probation or parole meetings, the fewer the number of days the adolescent was incarcerated, and the fewer days the adolescent lived at home prior to treatment. Results from exploratory analyses suggest that parents and adolescents are more discrepant when the assessment occurs later in the adolescent's treatment program. Overall, results suggest that in the absence of a cooperative teen, parental report of the adolescent's previous substance use could serve as a good proxy among families in which the adolescent is entering residential substance abuse treatment.

    Background The association between overweight and gastrointestinal symptoms has been recently studied in the literature; however, few studies have evaluated the association between overweight and constipation in adolescents in a community-based sample. The aim of this study was to analyze the prevalence of constipation and its association with being overweight in a community-based survey with adolescents. Methods This cross-sectional study included 1,077 adolescents who were enrolled in five schools in the city of Sao José dos Campos, Brazil. Constipation was defined according to modified and combined Rome III criteria for adolescents and adults. Being overweight was defined as a body mass index (BMI) that was equal to or greater than that of the 85th percentile for age and gender. Results Constipation was diagnosed in 18.2% (196/1077) of the included adolescents. There was no significant difference in the prevalence of constipation in males and females who were both younger and older than 14 years. Fecal incontinence was observed in 25 adolescents, 22 (88.0%) of whom were diagnosed as being constipated. The prevalence of being overweight was found in 13.5% (145/1077) of the study population. The prevalence of constipation was observed to be similar in adolescents who were (19.4%; 28/144) and were not (18.0%; 168/933) overweight (p = 0.764; OR = 1.10). Fecal incontinence that was associated with constipation was more frequent in adolescents who were overweight (37.0%; 8/28) than in adolescents who were not overweight (8.5%; 14/168; p = 0.005; OR = 4.40). Conclusions The prevalence of constipation was high among the investigated adolescents. There was no association between being overweight and constipation; however, an association between being overweight and fecal incontinence in constipated adolescents was confirmed. PMID:21496346

    Little is known about the economic socialization of children and adolescents and the role of parents in this process. The authors' purpose was to explore the role of parenting in the intergenerational transfer of economic orientation and economic behavior. More specifically, they studied the link between four parenting dimensions (parental warmth-responsiveness, behavioral control, psychological control, autonomy granting), three parenting styles (authoritative, authoritarian, and neglectful) and adolescents' conscientiousness, future time perspective, and present hedonistic orientation. The authors also studied the relationships between these dispositions and the adolescents' spending preferences and ability to control spending. They used data collected from 14-16-year-olds (n = 597) and their parents (n = 469) in Norway. Results showed that adolescents who perceived their parents as psychologically controlling were less future oriented and conscientious, and were more present hedonistic oriented than others, while adolescents who perceived their parents as responsive, autonomy granting, and controlling of behavior were more future orientated and conscientious than others. Adolescents' scores for conscientiousness and future orientation were negatively associated with preferences for spending and positively with the ability to control spending, while the opposite relationships were found with respect to a present hedonistic orientation. Parental style was also found to be important for the future educational plans of adolescents, and plans for higher education were more frequent among adolescents who characterized their parents as authoritative than among those who perceived their parents as neglectful. Implications of the findings for economic socialization are discussed.

    The association between the impaired cognitive control and brain regional abnormalities in Internet gaming disorder (IGD) adolescents had been validated in numerous studies. However, few studies focused on the role of the salience network (SN), which regulates dynamic communication among brain core neurocognitive networks to modulate cognitive control. Seventeen IGD adolescents and 17 healthy controls participated in the study. By combining resting-state functional connectivity and diffusion tensor imaging (DTI) tractography methods, we examined the changes of functional and structural connections within SN in IGD adolescents. The color-word Stroop task was employed to assess the impaired cognitive control in IGD adolescents. Correlation analysis was carried out to investigate the relationship between the neuroimaging indices and behavior performance in IGD adolescents. The impaired cognitive control in IGD was validated by more errors during the incongruent condition in color-word Stroop task. The right SN tract showed the decreased fractional anisotropy (FA) in IGD adolescents, though no significant differences of functional connectivity were detected. Moreover, the FA values of the right SN tract were negatively correlated with the errors during the incongruent condition in IGD adolescents. Our results revealed the disturbed structural connectivity within SN in IGD adolescents, which may be related with impaired cognitive control. It is hoped that the brain-behavior relationship from network perspective may enhance the understanding of IGD.

    Cognitive theories emphasize the importance of attentional biases in the development and maintenance of depression. Noteworthy, recent studies indicate that depression-related biases only occur in later stages of attentional processing. This is consistent with the idea that attention is a multicomponent process, consisting of at least two mechanisms: selection and inhibition. Therefore, this study aims to investigate interference and inhibition toward angry and happy stimuli in dysphoric adolescents compared to nondysphoric adolescents. To examine interference and inhibition of emotional information in 21 dysphoric (17 girls) and 28 nondysphoric adolescents (17 girls), 10-16 years of age, a Negative Affective Priming task was used. In this task, a target has to be evaluated as positive or negative while ignoring a distractor. As expected, dysphoric adolescents showed both higher interference from and higher inhibition of angry stimuli relative to nondysphoric adolescents. In contrast, happy stimuli did not lead to interference and consequently did not have to be inhibited in either group. Finally, a positive relation was found between interference and the subsequent inhibition of emotional stimuli. These observations confirm the existence of a bias toward angry faces in dysphoric adolescents and indicate a higher inhibition of angry faces in dysphoric adolescents compared to nondysphoric adolescents. The obtained results are different from those of similar previous studies in depressed or dysphoric adults using sad faces or negatively valenced words and might reveal important emotion-specific or age-specific inhibitory biases.

    Current concepts suggest that exposure to THC during adolescence may act as a risk factor for the development of psychiatric disorders later in life. However, the molecular underpinnings of this vulnerability are still poorly understood. To analyze this, we investigated whether and how THC exposure in female rats interferes with different maturational events occurring in the prefrontal cortex during adolescence through biochemical, pharmacological and electrophysiological means. We found that the endocannabinoid system undergoes maturational processes during adolescence and that THC exposure disrupts them, leading to impairment of both endocannabinoid signaling and endocannabinoid-mediated LTD in the adult prefrontal cortex. THC also altered the maturational fluctuations of NMDA subunits, leading to larger amounts of gluN2B at adulthood. Adult animals exposed to THC during adolescence also showed increased AMPA gluA1 with no changes in gluA2 subunits. Finally, adolescent THC exposure altered cognition at adulthood. All these effects seem to be triggered by the disruption of the physiological role played by the endocannabinoid system during adolescence. Indeed, blockade of CB1 receptors from early to late adolescence seems to prevent the occurrence of pruning at glutamatergic synapses. These results suggest that vulnerability of adolescent female rats to long-lasting THC adverse effects might partly reside in disruption of the pivotal role played by the endocannabinoid system in the prefrontal cortex maturation.

    Studies have shown that many smokers begin using nicotine during adolescence, yet the influence of early nicotine use on the response to other drugs of abuse in adulthood is not fully understood. In the current study, nicotine was administered to adolescent and adult rats for seven days. Thirty days later, cocaine-induced locomotor activity and cocaine self-administration were examined when the rats pretreated as adolescents were adults. Rats exposed to nicotine during early adolescence were sensitized thirty days later to the locomotor-activating effects of cocaine and self-administered a greater number of cocaine infusions than adolescent rats pretreated with vehicle. As a result of this increased intake, the cocaine self-administration dose-response curve was shifted upward indicating an increase in cocaine reinforcement. Rats pretreated with nicotine as adults, however, did not show a difference in locomotor activity or cocaine self-administration thirty days later compared to adult rats pretreated with vehicle. These findings suggest that early exposure to nicotine has long-term consequences on cocaine use. These data further suggest that nicotine use may carry a greater risk during adolescence than adulthood and adolescents who smoke may be particularly vulnerable to stimulant use.

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

    Existing studies of the sexual content of television programming and advertising and the effects of this content on adolescent viewers are reviewed. Content studies show that the frequency of sexual references have increased in the past decade and are increasingly explicit. Studies of the effects of this content, while scarce, suggest that adolescents who rely heavily on television for information about sexuality will have high standards of female beauty and will believe that premarital and extramarital intercourse with multiple partners is acceptable. They are unlikely to learn about the need for contraceptives as a form of protection against pregnancy or disease. Suggestions for future research and trends in television programming policies are explored.

  7. Adolescent sleep patterns in humans and laboratory animals.

    PubMed

    Hagenauer, Megan Hastings; Lee, Theresa M

    2013-07-01

    This article is part of a Special Issue "Puberty and Adolescence". One of the defining characteristics of adolescence in humans is a large shift in the timing and structure of sleep. Some of these changes are easily observable at the behavioral level, such as a shift in sleep patterns from a relatively morning to a relatively evening chronotype. However, there are equally large changes in the underlying architecture of sleep, including a >60% decrease in slow brain wave activity, which may reflect cortical pruning. In this review we examine the developmental forces driving adolescent sleep patterns using a cross-species comparison. We find that behavioral and physiological sleep parameters change during adolescence in non-human mammalian species, ranging from primates to rodents, in a manner that is often hormone-dependent. However, the overt appearance of these changes is species-specific, with polyphasic sleepers, such as rodents, showing a phase-advance in sleep timing and consolidation of daily sleep/wake rhythms. Using the classic two-process model of sleep regulation, we demonstrate via a series of simulations that many of the species-specific characteristics of adolescent sleep patterns can be explained by a universal decrease in the build-up and dissipation of sleep pressure. Moreover, and counterintuitively, we find that these changes do not necessitate a large decrease in overall sleep need, fitting the adolescent sleep literature. We compare these results to our previous review detailing evidence for adolescent changes in the regulation of sleep by the circadian timekeeping system (Hagenauer and Lee, 2012), and suggest that both processes may be responsible for adolescent sleep patterns.

    Background: Previous studies investigated neural substrates of emotional face processing in adolescents and its comparison with adults. As emotional faces elicit more of emotional expression recognition rather than direct emotional responding, it remains undetermined how adolescents are different from adults in brain susceptibility to emotionally stressful stimuli. Methods: Event-Related Potentials (ERPs) were recorded for highly negative (HN), moderately negative (MN), and neutral pictures in 20 adolescents and 20 adults while subjects performed a standard/deviant distinction task by pressing different keys, irrespective of the emotionality of deviant stimuli. Results: Adolescents exhibited more negative amplitudes for HN vs. neutral pictures in N1 (100–150 ms), P2 (130–190 ms), N2 (210–290 ms), and P3 (360–440 ms) components. In addition, adolescents showed more negative amplitudes for MN compared to neutral pictures in N1, P2, and N2 components. By contrast, adults exhibited significant emotion effects for HN stimuli in N2 and P3 amplitudes but not in N1 and P2 amplitudes, and they did not exhibit a significant emotion effect for MN stimuli at all these components. In the 210–290 ms time interval, the emotion effect for HN stimuli was significant across frontal and central regions in adolescents, while this emotion effect was noticeable only in the central region for adults. Conclusions: Adolescents are more emotionally sensitive to negative stimuli compared to adults, regardless of the emotional intensity of the stimuli, possibly due to the immature prefrontal control system over the limbic emotional inputs during adolescence.

    One of the special challenges in immunization policy is communication and access to adolescents. To identify barriers and enablers for the immunization of this specific target group, we conducted 11 focus group discussions with adolescents with and without migration background, mothers with Turkish and Russian migration background, and physicians in private practice in March 2011. The results showed that for adolescents, the utilization of immunization was guided by informational and organizational processes in families and by the consulting physician. The low awareness of immunization-related issues that was observed among adolescents is especially challenging, because routine visits to the doctor often stop with the transition from pediatric to adult health care. Immigration-related factors may additionally affect the utilization of immunization services. Besides improving access to information and lowering the barriers to immunization for adolescents in general, culturally sensitive interventions may be a promising approach for improving communication between mothers and the immunizing physician and thereby improving vaccination coverage in the adolescent target group.

    It is hypothesized that hypothalamic-pituitary-adrenal and hypothalamic-pituitary-gonadal axes function together to maintain adaptive functioning during stressful situations differently in adolescence than the characteristic inverse relations found in adulthood. We examined within-person correlated changes (coupling) in cortisol, DHEA and testosterone in response to parent-adolescent conflict discussion, social performance, and venipuncture paradigms. Data are derived from two samples of boys and girls from the Northeastern US (213 adolescents aged 11-16, M=13.7, SD=1.5 years; 108 adolescents aged 9-14, M=11.99, SD=1.55) using different biological sampling vehicles (saliva and blood). Results consistently show that across samples, vehicles, and contexts, cortisol and DHEA and cortisol and testosterone are positively coupled in response to environmental stimuli. Findings underscore the importance of considering the effects of multiple hormones together in order to further our understanding of the biological underpinnings of behavior, especially during adolescence, as adolescence is a developmental transition period that may be qualitatively different from adulthood in terms of hormone functioning.

    Adults are proficient in extracting identity cues from faces. This proficiency develops slowly during childhood, with performance not reaching adult levels until adolescence. Bodies are similar to faces in that they convey identity cues and rely on specialized perceptual mechanisms. However, it is currently unclear whether body recognition mirrors the slow development of face recognition during childhood. Recent evidence suggests that body recognition develops faster than face recognition. Here we measured body and face recognition in 6- and 10-year-old children and adults to determine whether these two skills show different amounts of improvement during childhood. We found no evidence that they do. Face and body recognition showed similar improvement with age, and children, like adults, were better at recognizing faces than bodies. These results suggest that the mechanisms of face and body memory mature at a similar rate or that improvement of more general cognitive and perceptual skills underlies improvement of both face and body recognition.

    The purpose of this study is to explore narcissistic and prosocial behaviors as reported by adolescents with and without substance dependency disorder (SDD). This study employs a quasi-experimental design using SDD adolescents compared with two normative samples of adolescents. In comparison to normative adolescents, adolescents with SDD were strongly distinguished by overt narcissistic behaviors and less monetary giving. Levels of narcissistic and prosocial behaviors among adolescents with SDD suggest a connection between self-centeredness and addiction. Results also suggest volunteerism as a potential option to counter narcissism in substance dependent adolescents.

    On two occasions separated by one year, Chinese adolescents with economic disadvantage in Hong Kong (N = 199) responded to instruments measuring perceived parental parenthood qualities (indexed by perceived parenting styles, support and help from parents, and conflict and relationship with the parents) and psychosocial adjustment (psychological well-being, substance abuse, and delinquency). Results showed that parental parenthood variables were concurrently associated with different measures of adolescent psychological well-being and problem behavior at Time 1 and Time 2. While paternal parenthood qualities at Time 1 predicted changes in existential well-being and delinquency in adolescent boys, but not in adolescent girls, at Time 2, maternal parenthood qualities at Time 1 predicted changes in the mental health and problem behavior in adolescent girls, but not in adolescent boys, at Time 2. There is no strong support for the thesis that adolescent adjustment influences perceived parental parenthood qualities over time. The present study suggests that the influences of fathers and mothers on the adjustment of Chinese adolescents experiencing economic disadvantage vary with the gender of adolescent children.

    Depression in adolescence and adulthood is common, afflicting up to 20 percent of these populations. It represents a significant public health concern and is associated with considerable suffering and functional impairment. Adolescent-onset depression tends to be a particularly malignant and recalcitrant condition, increasing the likelihood of recurrence and chronicity in adulthood. Clinical presentations for various medical and psychiatric conditions, as well as reactions to psychosocial stressors, can mimic or confound the picture of depression in adolescents. Therefore, careful assessment and differential diagnosis is essential. Effective treatments, both pharmacological and psychosocial in nature, exist, and so early detection and intervention is paramount. This article presents an overview of optimal prevention, assessment, and clinical decision-making strategies for managing depression in adolescents. PMID:19855857

    Obsessive-compulsive disorder (OCD) is a frequent and disabling disorder with a long delay in seeking help that could partly be due to poor mental health literacy and stigmatizing attitudes. This study analyzes the mental health literacy and stigma associated with symmetry/order and aggression-related OCD in a Spanish adolescent sample. This age group was chosen because adolescence is a vulnerable period for the development of OCD, and adolescents are often reluctant to seek professional help. One hundred and two non-clinical adolescents read two vignettes describing symmetry/order and aggression-related OCD. Then, referring to these two vignettes, they answered questions related to problem recognition, causality perception, need for treatment, treatment recommendations, and stigma. Results show that a high percentage of adolescents recognize the interference of order- and aggression-related OCD, consider that a peer with order- or aggression-related OCD needs treatment, and would recommend a formal source of help. Although order symptoms are highly recognized as OCD by adolescents, aggression-related OCD is frequently misidentified as schizophrenia or depression. Results also show higher levels of stigmatizing attitudes in adolescents, associated with aggression-OCD (versus order-OCD), especially in male adolescents and adolescents with no previous experience with mental health services/providers. Results suggest the need to develop school-based programs emphasizing OCD content heterogeneity, especially the aggression, sexual, and religious contents, and work toward eliminating stigma.

    The main aim of this study was to compare the frequency and correlates of DSM-IV anxiety disorder symptoms among non-referred adolescents in Germany and in Hong Kong. A total of 1,022 adolescents (594 from Germany and 428 from Hong Kong) between the ages of 12 and 17 years were investigated. Results showed that adolescents in Hong Kong reported significantly higher levels of anxiety symptoms than adolescents in Germany. Anxiety symptoms showed different correlates in different cultures. Specifically, academic motivational goals to compete to get good grades and to be rewarded for their performance correlated significantly with anxiety symptoms in Hong Kong. In Germany, anxiety symptoms correlated significantly with reinforcement received for anxiety-related problems (i.e., instrumental learning) and with parental verbal transmission about the danger of anxiety (i.e., informational learning). The findings underscore the importance of cultural factors on adolescent's anxiety.

    Few studies have focused on the relationships among religiousness, social support and subjective well-being in Chinese adolescent populations. This study tries to fill this gap. Using cluster sampling, we selected two groups: Group A, which included 738 Tibetan adolescents with a formal religious affiliation and represented adolescents from a religious culture, and Group B, which included 720 Han adolescents without a religious affiliation and represented adolescents from an irreligious culture. Structural equation modelling showed that only in Group A did social support mediate (partially) the relationship between religious experience and subjective well-being; furthermore, the results of a hierarchical regression analysis showed that only in Group A did social support moderate the relationship between religious ideology and subjective well-being. Possible explanations for the discrepancies between the findings obtained in this study and those obtained in previous studies are discussed.

    We report findings from a follow-up survey of clinicians from the STeP study that assessed their attitudes toward and current use of the Accu-Chek(®) 360° View tool (Roche Diagnostics, Indianapolis, IN) approximately 2 years after the study was completed. The Accu-Chek 360° View tool enables patients to record/plot a seven-point self-monitoring of blood glucose (SMBG) profile (fasting, preprandial/2-h postprandial at each of the three meals, and bedtime) on 3 consecutive days, document meal sizes and energy levels, and comment on their SMBG experiences. Our findings showed that the majority of these physicians continue to use the tool with their patients, citing enhanced patient understanding and engagement, better discussions with patients regarding the impact of lifestyle behaviors, improved clinical outcomes, and better practice efficiencies as significant benefits of the tool.

    A large literature shows that parent and sibling relationship factors are associated with an increased likelihood of adolescent substance use. Less is known about the etiology of these associations. Using a genetically-informed sibling design, we examined the prospective associations between parent involvement, sibling companionship, and adolescent substance use at two points in mid- and late-adolescence. Adolescents were adopted (n = 568) or the biological offspring of both parents (n = 412). Cross-lagged panel results showed that higher levels of parent involvement in early adolescence were associated with lower levels of substance use later in adolescence. Results did not significantly differ across adoption status, suggesting this association cannot be due to passive gene-environment correlation. Adolescent substance use at Time 1 was not significantly associated with parent involvement at Time 2, suggesting this association does not appear to be solely due to evocative (i.e. “child-driven”) effects either. Together, results support a protective influence of parent involvement on subsequent adolescent substance use that is environmental in nature. The cross-paths between sibling companionship and adolescent substance use were significant and negative in direction (i.e., protective) for sisters, but positive for brothers (in line with a social contagion hypothesis). These effects were consistent across genetically related and unrelated pairs, and thus appear to be environmentally mediated. For mixed gender siblings, results were consistent with environmentally-driven, protective influence hypothesis for genetically unrelated pairs, but in line with a genetically influenced, social contagion hypothesis for genetically related pairs. Implications are discussed. PMID:26030026

    The present study examined the prospective relationship between parental education and adolescents' soft drink intake over 20 months, and possible mediating effects of adolescents' availability and accessibility of soft drinks at home. A total of 866 adolescents, with data on two time points in the Norwegian HEalth In Adolescents (HEIA) cohort study (2007-9), were included in the analyses. Data on intake and determinants of soft drinks were collected from adolescents and both parents by questionnaires. Mediation analyses using linear regression investigated the total and direct effects of parental education on adolescents' soft drink intake from the age of 11-13 years. In order to investigate prospective relationships, two models were set up to measure the (1) prediction and (2) change in consumption over 20 months. Possible mediation effects of availability and perceived accessibility at home were further examined in both models. The results showed that a lower level of parental education predicted a higher intake of soft drinks among adolescents after 20 months, and that higher perceived accessibility of soft drinks reported by adolescents and mothers explained 39 % of the total effect. No relationship was observed between parental education and the change in adolescents' intake of soft drinks over 20 months. Interventions aimed at families with low parental education should target the perceived accessibility of soft drinks at home in order to diminish social differences in adolescents' soft drink consumption.

    The Calypso trial showed an improved progression-free survival with PEG-liposomal doxorubicin (PLD) and carboplatin (P) as compared with the standard regimen paclitaxel (PCLTX) and P in the second- or third-line treatment of platinum-sensitive epithelial ovarian cancer [1]. A panel of Austrian gynecologic oncologists discussed the clinical consequences of the data from the Calypso study for the routine practice. PLD + P had a significantly lower rate of alopecia and neuropathy than the taxane regimen, both toxicities which compromise the quality of life. Due to possible significant thrombocytopenia, the blood counts of patients undergoing PLD + P therapy should be monitored weekly. Patients receiving PLD/P are at higher risk of nausea and vomiting. Palmoplantar erythrodysesthesia (hand-foot syndrome) is a significant toxicity of PLD + P most prevalent after the third or fourth cycle. Prophylaxis consists of avoiding pressure on feet and hands and other parts of the body. Similarly, prophylaxis of mucositis seems important and includes avoiding consumption of hot, spicy and salty foods and drinks. Mouth dryness should be avoided. Premedication with antiemetics and dexamethasone dissolved in 5% glucose is done to prevent hypersensitivity to PLD. In conclusion, the therapeutic index is more favorable for PLD + P than for PCTX + P.

    Background Anxiety and depression have been considered to be neglected disorders in epilepsy. Because panic disorder is one of the most important anxiety disorders, it has been problematic to use very comprehensive anxiety questionnaires in epilepsy patients, as panic attacks and epileptic seizures, although two distinct clinical entities from a diagnostic point of view, show a significant overlap of symptoms. Aims We have focused on single items for anxiety and depression as screening candidates in adolescent epilepsy. Methods The individual panic attack item in the Screen for Children Anxiety Related Emotional Disorders Scale (SCARED) and the single depression item in the Kellner Symptom Questionnaire were tested. Our samples consisted of adolescent patients with epilepsy and a matched control group with healthy participants, as well as two numerical groups acting as controls. Results The single panic attack item identified panic anxiety in 24.1% in the group of patients with epilepsy and 0.0% in the matched control group (p = 0.01). The single depression item identified 52.2% with depression in the epilepsy group and 6.2% in the matched control group (p = 0.001). Conclusion As screening instruments, single items of panic attack and depression are sufficient to screen for these affective states in adolescent epilepsy. The clinical implications are that it is important to be quite specific when screening for depression and panic attacks in adolescent patients with epilepsy.

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

    Adolescence is a transitional, developmental phase with marked shifts in behavior, particularly as related to risk-taking and experimentation. Genetic influences on adolescent behavior also show marked changes across this developmental period; in fact, adolescence showcases the dynamic nature of genetic influences on human behavior. Using the twin studies literature on alcohol use and misuse, we highlight several principles of genetic influence on adolescent behavior. We illustrate how genetic influences change (increase) across adolescence, as individuals have more freedom to express their predispositions and to shape their social worlds. We show how there are multiple genetic pathways to risk, and how the environment can moderate the importance of genetic predispositions. Finally, we review the literature aimed at identifying specific genes involved in adolescent behavior and understanding how identified genes impact adolescent outcomes. Ultimately, understanding how genetic predispositions combine with environmental influences to impact pathways of risk and resilience should be translated into improved prevention and intervention efforts; this remains a rich area for future research.

    The study is aimed at providing the development and initial validation of the Design My Future (DMF), which may be administered in career counseling and research activities to assess adolescents' future orientation and resilience. Two studies with two independent samples of Italian adolescents were conducted to examine psychometric requisites of DMF. Specifically, in the first study, after developing items and examined the content validity, the factorial structure, reliability and discriminant validity of the DMF were tested. In the second study, the measurement invariance across gender, conducing a sequence of nested CFA models, was evaluated. Results showed good psychometric support for the instrument with Italian adolescents.

    Mental health status of 726 adolescents and their backgrounds were investigated with Symptom Check List(SCL-90) and self-designed questionnaire. The results showed that the prevalence rate of psychological problems ranged from 6.34% to 24.93%. Among these problems, obsession led all the others. Females had higher scores in interpersonal sensitivity, depression, anxiety, phobia than males. Logistic regression analysis indicated that the major factors contributed to mental health status of adolescents were the relationship between teacher and student, father's concern with his child, only child or not, parents' expectations, personality and sex. The study provides reference source for improving the mental health status of adolescents.

    Using interview and self-administered survey data, this article examines how homes, schools, and the community spaces between these two locations affect adolescent nutrition in a low-income, urban setting. Results from this research show that eating location can play a significant role in the foods that adolescents consume. Food acquisition data provided by adolescents reveal that homes and schools provide spaces for the consumption of healthy foods while shops, restaurants, takeouts, and community centers contribute unhealthy snack foods to adolescent diets in a traditionally low-income, urban neighborhood in Northern Ireland. The results of this research show that eating location can provide a starting point for designing healthy eating interventions in low-income places to avoid overlap with spaces that already provide healthy foods to young people.

    This study analyzes the relationship between a multidimensional measure of self-concept, the Self-concept Form-5 Questionnaire (AF5), and drug use among adolescents. From the responses of 632 participants (47.5% females) aged 12 to 17 years (M = 14.88 years, SD = 1.71 years), results showed negative relationships between family, academic and physical self-concept, and drug use. Although a positive relationship between social self-concept and drug use was found, this significant relationship disappeared once the age and sex of adolescents was controlled statistically. Moreover, the study includes other adjustment indicators in adolescence (psychological adjustment, personal competence, antisocial behavior and parenting). Results support the idea of self-concept as an important correlate of psychological well-being and a basic theoretical construct for explaining adjusted and adaptive behaviors in adolescence. Likewise, our results underline the need for statistical control of the effect of a third variable (sex), which could explain some contradictory results reported in the literature (a positive relationship between social self-concept and drug use), so as to avoid reaching conclusions based on spurious relationships. self-concept, multigroup confirmatory factor analysis, adolescence, psychosocial adjustment, drug use.

    To better understand adolescents experiencing peer victimization, ostracism, and emotional health problems, this study aimed to describe a cohort of middle school students identified as having school peer-related social difficulties as 2 groups: those with mental health diagnoses (MHDs; n = 17) and those without diagnoses (n = 8). Participants were administered a test battery to examine communication ability, social responsiveness, social activity, ostracism, victimization, and emotional health. Results showed that adolescents with MHDs, relative to those without, scored significantly lower on measures of communication ability, social responsiveness, and social activity but similarly on measures of victimization, ostracism, and internalizing/externalizing factors. Results suggest that adolescents with and without MHDs can endure ostracism and peer victimization to a similar extent. Because ostracism and victimization have serious morbidity in adolescents, physicians and caregivers must look for signs in all adolescents, irrespective of MHD. Recommendations for appropriate primary care management are discussed.

    The technique of suppressing secondary electron emission (SEE) from a surface by texturing it is developing rapidly in recent years. We have specific and general results in support of this technique: We have performed numerical and analytic calculations for determining the effective secondary electron yield (SEY) from velvet, which is an array of long cylinders on the micro-scale, and found velvet to be suitable for suppressing SEY from a normally incident primary distribution. We have performed numerical and analytic calculations also for metallic foams, which are an isotropic lattice of fibers on the micro-scale, and found foams to be suitable for suppressing SEY from an isotropic primary distribution. More generally, we have created a geometric weighted view factor model for determining the SEY suppression of a given surface geometry, which has optimization of SEY as a natural application. The optimal surface for suppressing SEY does not have finite area and has no smallest feature size, making it fractal in nature. This model gives simple criteria for a physical, non-fractal surface to suppress SEY. We found families of optimal surfaces to suppress SEY given a finite surface area.

    Considering that scientific articles have emphasized the link between the onset of sexual life and peer pressure, the aim of this study was to identify peer pressure in the adolescents' sexual initiation from the point of view of their relationship with the group of friends. A cross-sectional study was conducted among 363 15-19 year-old teens that represented a sample ofthe adolescents enrolled in a family health unit in Sao Paulo City, Brazil. Results showed a relation between sexual initiation and age, being involved in physical experience with someone without wishing, having the majority of friends with sexual experience and dating. Eventually, data show that peers might play some influence on adolescents' option for sexual debut.

    Synthetic cannabinoids (SCs) have rapidly proliferated as recreational drugs, and may present a substantial health risk to vulnerable populations. However, information on possible effects of long-term use is sparse. This study compared acute and residual effects of the popular indazole carboxamide SC compounds AB-PINACA and AB-FUBINACA in adolescent rats with ∆(9)-tetrahydrocannabinol (THC) and control treatments. Albino Wistar rats were injected (i.p.) with AB-PINACA or AB-FUBINACA every second day (beginning post-natal day (PND) 31), first at a low dose (0.2 mg/kg on 6 days) followed by a higher dose (1 mg/kg on a further 6 days). THC-treated rats received equivalent doses of 6 × 1 mg/kg and 6 × 5 mg/kg. During drug treatment, THC, AB-PINACA, and AB-FUBINACA decreased locomotor activity at high and low doses, increased anxiety-like behaviours and audible vocalisations, and reduced weight gain. Two weeks after dosing was completed, all cannabinoid pre-treated rats exhibited object recognition memory deficits. These were notably more severe in rats pre-treated with AB-FUBINACA. However, social interaction was reduced in the THC pre-treated group only. Six weeks post-dosing, plasma levels of cytokines interleukin (IL)-1α and IL-12 were reduced by AB-FUBINACA pre-treatment, while cerebellar endocannabinoids were reduced by THC and AB-PINACA pre-treatment. The acute effects of AB-PINACA and AB-FUBINACA were broadly similar to those of THC, suggesting that acute SC toxicity in humans may be modulated by dose factors, including inadvertent overdose and product contamination. However, some lasting residual effects of these different cannabinoid receptor agonists were subtly different, hinting at recruitment of different mechanisms of neuroadaptation.

    Long-term ECG is widely used in diagnosis and assessment of many cardiac symptoms which may be caused by dangerous arrhythmias that sometimes can be difficult to document. The PocketECG system is a new technological solution for a long-term, noninvasive, continuous and real-time ECG monitoring that provides automatic diagnosis of dysrhythmias. ECG data transmission occurs over a mobile network. The goal of this study was to assess the reliability of long-term ECG recordings acquired with the PocketECG system. One hundred and fifteen patients (43 girls and 72 boys) of an average age of 15.5 ± 2.5 years were examined at the Department of Cardiology at the Children's Memorial Health Institute. Two simultaneous 24-h ECG recordings were conducted: one with a Holter monitor and one with the PocketECG system. A linear correlation was demonstrated between the two methods with regard to the recorded QRS complexes [H = 1173.0 (-1946.40; 4838.50) + PocketECG*0.98 (0.94; 1.02)]. Mean diurnal heart rhythms were comparable (p > 0.05) despite the fact that the slowest and the fastest rates were different. The rate of detection for ventricular, supraventricular dysrhythmias and pauses in ventricular rhythm were comparable in both methods. The PocketECG system for continuous and real-time ECG recording is a reliable method for the assessment of heart rhythm and dysrhythmias in children and adolescents.

    Relatively few data are available on the prevalence of hyperthyroidism (TSH concentrations of < 0.3 mIU/L, with normal or elevated concentrations of free T4) in individuals exposed to radioiodines at low levels. The accident at the Chornobyl (Chernobyl) nuclear plant in Ukraine on April 26, 1986 exposed large numbers of residents to radioactive fallout, principally to iodine-131 (I-131) (mean and median doses = 0.6 Gray (Gy) and 0.2 Gy). We investigated the relationship of I-131 and prevalent hyperthyroidism among 11,853 individuals exposed as children or adolescents in Ukraine who underwent an in-depth, standardized thyroid gland screening examination 12–14 years later. Radioactivity measurements taken shortly after the accident were available for all subjects and were used to estimate individual thyroid doses. We identified 76 cases of hyperthyroidism (11 overt, 65 subclinical). Using logistic regression, we tested a variety of continuous risk models and conducted categorical analyses for all subjects combined and for females (53 cases, n=5,767) and males (23 cases, n=6,086) separately, but found no convincing evidence of a dose response relationship between I-131 and hyperthyroidism. There was some suggestion of elevated risk among females in an analysis based on a dichotomous dose model with a threshold of 0.5 Gy chosen empirically (OR=1.86, P=0.06), but the statistical significance level was reduced (P=0.13) in a formal analysis with an estimated threshold. In summary, after a thorough exploration of the data, we found no statistically significant dose response relationship between individual I-131 thyroid doses and prevalent hyperthyroidism.
