Little is known about how socioeconomic status (SES) affects dietary intake among adolescents. This study assessed whether dietary behaviors of 12- to 17-year-old adolescents differed by SES, using eligibility for free or reduced price (FRP) school meals as a measure of SES. After parental consent w...

Self-reported dietary caffeine and alcohol consumption were examined in relation to anger and violent behavior in Icelandic tenth-graders. Structural equation modeling (SEM) was used to investigate direct and indirect effects of measured and latent variables in the population sample of 3,670, controlling for parental financial standing, family structure, ADHD, and peer delinquency. Gender differences were observed that have not been reported previously, especially in relation to anger as a possible mediator of violent behavior against a background of caffeine and alcohol consumption. Study findings suggest the need to take account of caffeine consumption in relation to adolescent anger and violence.
Background Few lifestyle factors have been simultaneously studied and reported for Saudi adolescents. Therefore, the purpose of the present study was to report on the prevalence of physical activity, sedentary behaviors and dietary habits among Saudi adolescents and to examine the interrelationships among these factors using representative samples drawn from three major cities in Saudi Arabia. Methods This school-based cross-sectional study was conducted during the years 2009-2010 in three cities: Al-Khobar, Jeddah and Riyadh. The participants were 2908 secondary-school males (1401) and females (1507) aged 14-19 years, randomly selected using a multistage stratified sampling technique. Measurements included weight, height, sedentary behaviors (TV viewing, playing video games and computer use), physical activity using a validated questionnaire and dietary habits. Results A very high proportion (84% for males and 91.2% for females) of Saudi adolescents spent more than 2 hours on screen time daily and almost half of the males and three-quarters of the females did not meet daily physical activity guidelines. The majority of adolescents did not have a daily intake of breakfast, fruit, vegetables and milk. Females were significantly (p < 0.05) more sedentary, much less physically active, especially with vigorous physical activity, and there were fewer days per week when they consumed breakfast, fruit, milk and diary products, sugar-sweetened drinks, fast foods and energy drinks than did males. However, the females' intake of French fries and potato chips, cakes and donuts, and candy and chocolate was significantly (p < 0.05) higher than the males'. Screen time was significantly (p < 0.05) correlated inversely with the intake of breakfast, vegetables and fruit. Physical activity had a significant (p < 0.05) positive relationship with fruit and vegetable intake but not with sedentary behaviors. Conclusions The high prevalence of sedentary behaviors, physical inactivity and

Skill-based education has been shown to reduce high-risk behavior among adolescents, but in India, life skills have often been looked at only from the reproductive health perspective. Therefore, the current study was undertaken to assess the effect of life skills training on dietary behavior of adolescents studying in grades 9 and 11 of 2 schools in Delhi. This was a nonrandomized interventional study with a control group. A self-administered questionnaire was used for assessment of dietary behavior at baseline, 15 days, and 3 months after the life skills training. Two life skills training sessions were imparted to the intervention group, focusing on the use of life skills in making healthy choices. Participants in the intervention group (n = 180) showed significant improvement in knowledge (P < .001), attitude (P = .007), and practices (P < .001) following the life skills training. To conclude, a skills-based approach does help improve the dietary behavior in adolescents.

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

Background The population of the United States is becoming increasingly ethnically and racially diverse, much of it due to immigration patterns. However little is known about dietary intake and weight-related concerns and behaviors of youth from some ethnic-minority groups, especially Hispanic, Hmong, and Somali adolescents. Objective To describe dietary intake and weight-related concerns and behaviors among Hispanic, Hmong, and Somali adolescents and compare them to white adolescents. Design Cross-sectional analysis of data from EAT 2010 (Eating and Activity in Teens), a population-based study in the Minneapolis/St. Paul metropolitan area. Participants/Setting Current analysis includes 1,672 adolescents (Hispanic: n=562(33.6%); Hmong: n=477(28.5%); Somali: n=113(6.8%); White: n=520 (31.1%); mean age=15.0). Adolescents completed classroom surveys and had their height/weight measured during the 2009–2010 academic year. Statistical Analysis Multivariable regression models, adjusted for socioeconomic status, age, and school as a random effect were used to examine racial/ethnic differences for each outcome variable for boys and girls. Results There are numerous differences in the behaviors of Hispanic, Hmong, and Somali adolescents as compared to whites. Hispanic and Somali youth consumed fruit and fast food more frequently. Hmong adolescents consumed sugar-sweetened beverages less frequently, while Somali boys consumed energy and sports drinks more frequently than whites. Compared to white boys, overweight/obesity was higher among Hispanic and Hmong. A higher percentage of Hmong and Somali adolescents engaged in unhealthy weight control behaviors. Body satisfaction was lower for all Hmong adolescents compared to whites. Conclusions There were varying areas of concern in dietary intake, weight, and weight-related concerns and behaviors among adolescents in all ethnic groups.

The purpose of this study was to design a rewards-based nutrition intervention program to improve knowledge and dietary behaviors of adolescent girls. Our participants consisted of eight girls ages 11 to 13 years. Nutritional knowledge was assessed before and after intervention program through a "Jeopardy" style quiz game and posttest questionnaires. Participants were also interviewed throughout the week about typical dietary behaviors, daily physical activity, and self-esteem. Educational activities took place for 2 to 3 hours each day and included a grocery store scavenger hunt, healthy baking demonstrations, and relay races. Participants received bracelets and charms as rewards for participation in activities. Nutritional knowledge increased for six out of eight participants, although the overall increase was not found to be statistically significant (p = .20). Significant correlations were found between measures including dietary behavior (soda consumption per week and perceived importance of body weight: r = -.827, p = .01), self-esteem (weight and endurance: r = .801, p = .03), and fitness levels (weight and curl-ups completed in 30 seconds: r = -.729, p = .04). This study shows promising evidence that this nutrition education intervention could be effective at increasing nutrition knowledge, thus potentially affecting future dietary behaviors of adolescent girls.

Autism spectrum disorder (ASD) is a neurodevelopmental disorder associated with restrictive or repetitive behaviors and difficulties with verbal and interpersonal communication, in which some problems involving nutrition may be present. This study aims to evaluate dietary intake and identify feeding behavioral problems in male children and adolescents with ASD when compared to matched controls, as well as parents or caregivers' feelings about strategies for dealing with eating problems. A 3-day food record was performed and nutrient intake was compared to the Dietary Reference Intake according to age. To evaluate children feeding behavior and parents or caregivers' feelings, the Behavior Pediatrics Feeding Assessment Scale (BPFA) was used. ASD patients consumed in average more calories than controls (though with a high patient's frequency above and below calorie range references), had a limited food repertoire, high prevalence of children with inadequate calcium, sodium, iron vitamin B5, folate, and vitamin C intake. BPFA scores were also higher in the ASD group when compared to controls for all frequencies (child behavior, parents and total). These findings lead us to endorse the importance of evaluating feeding problems in the clinical routine, considering also the singular features of the patients.

The aim of this study was to investigate whether body mass index (BMI), eating habits and sedentary behaviours were associated with sleep duration among Kuwaiti adolescents. The study is part of the Arab Teens Lifestyle Study (ATLS), which is a school-based cross-sectional multi-center collaborative study. A sample of 906 adolescents (boys and girls) aged 14-19 years was randomly selected from 6 Kuwaiti Governances using a multistage stratified cluster sampling technique. The findings revealed that the prevalence of overweight and obesity was 50.5% in boys and 46.5% in girls. The majority of boys (76%) and of girls (74%) fell into the short sleep duration category (6 hours/day or less). Sleep duration were found to be negatively associated with BMI (girls only). Watching television (boys and girls) and working on computers (boys only) were also negatively associated with sleep duration. While the consumption of breakfast (both genders) and milk (boys only) was positively associated with sleep duration (p<0.05). In contrast, the consumption of fast foods (both genders), sugar-sweetened drinks and sweets (boys only) potatoes (girls only) were negatively associated with sleep duration (p<0.05). It can be concluded that the majority of Kuwaiti adolescents exhibit insufficient sleep duration which was associated with obesity measure, a combination of poor eating habits and more sedentary behaviors. The findings also suggest gender differences in these associations. Therefore, adequate sleep is an important modifiable risk factor to prevent obesity and was positively associated with some unhealthy lifestyle habits.

Recent survey data reveal persistent race/ethnic disparities in prevalence of adiposity in U.S. children and adolescents. We examined race/ethnic differentials in time trends in dietary behaviors of Americans 2–19 y of age to understand if these trends track those observed for body weight. We used dietary data from the NHANES 1988–1994, 1999–2002, and 2003–2008 (n = 24,131) to examine changes in reported energy intake, amount of foods and beverages, number of eating occasions, and percent of energy from foods and beverages, among non-Hispanic white, non-Hispanic black, and Mexican American 2–19 y olds. Multivariable regression analyses appropriate for complex surveys were used to examine these associations. The secular increase in mean number of eating occasions was significant (P-trend < 0.0001) in all age and race/ethnic groups; however, a corresponding increase in the amount of foods and beverages, or total energy intake was not observed. In non-Hispanic black and Mexican American 2–5 and 12–19 y olds, the secular increase in number of eating occasions, and in non-Hispanic black 12–19 y olds, the increase in percent of energy from all beverages or non-nutritive beverages were greater relative to non-Hispanic whites. In conclusion, the observed race/ethnic differences in trajectory of changes in dietary behaviors over past 20 y were modest and were not accompanied by a significant increase in energy intake. Cautious interpretation is urged due to potential underreporting of dietary intake in national surveys. There was a suggestion of convergence in some race/ethnic differentials in dietary behaviors due to greater relative changes in possibly adverse behaviors in non-Hispanic blacks, especially adolescents.

This study explored friendship variables in relation to body image, dietary restraint, extreme weight-loss behaviors (EWEBs), and binge eating in adolescent girls. From 523 girls, 79 friendship cliques were identified using social network analysis. Participants completed questionnaires that assessed body image concerns, eating, friendship relations, and psychological family, and media variables. Similarity was greater for within than for between friendship cliques for body image concerns, dietary restraint, and EWLBs, but not for binge eating. Cliques high in body image concerns and dieting manifested these concerns in ways consistent with a high weight/shape-preoccupied subculture. Friendship attitudes contributed significantly to the prediction of individual body image concern and eating behaviors. Use of EWLBs by friends predicted an individual's own level of use.

Over one third of U.S. adolescents are overweight. A descriptive, cross-sectional study examined the relationship between student dietary self-efficacy (SE), sugar-sweetened beverages, and low-nutrient energy-dense food consumption, and exposure to a healthy school food environment without competitive foods. The sample consisted of 292 urban, primarily African American students aged 11 to 16 years. Mantel-Haenszel χ(2) analyses revealed a significant but weak linear trend for girls between number of school meals and SE to drink less soda, χ(2)(1) = 6.882, p = .008, and between semesters attended with SE to eat more fruits and vegetables, χ(2)(1) = 5.908, p = .015. Obese students had significantly higher scores for two SE items than nonobese students, that is, plan better nutrition, χ(2)(1) = 3.998, p = .045, and eat healthy at a fast-food restaurant, χ(2)(1) = 4.078, p = .043. Further study of adolescent SE for healthy eating and school-based, food-focused obesity prevention interventions is needed.

Recent survey data reveal the persistence of long-acknowledged socioeconomic status (SES) differentials in the prevalence of obesity in U.S. children and adolescents. We examined 30-y changes in the association of dietary and meal behaviors with family income and education to understand the possible contribution of these trends to SES trends in obesity rates in 2- to 19-y-old Americans. We used dietary and SES data for 2- to 19-y olds from the NHANES 1971-1974 to 2003-2008 (n = 39,822). The secular changes in the independent association of family income and education with 24-h dietary behaviors [energy intake (kcal), amount of foods and beverages (g), percent energy from all beverages and from nutritive beverages, and energy density of foods] and 24-h meal behaviors [number of eating occasions, energy from snack episodes (%), and mention of breakfast] were examined using multivariable regression methods. The secular increase in energy intake and food and beverage amount was significant in the lowest family SES categories. The positive association of family income and education with intakes of energy, food amounts, and beverage energy, noted in 1971-1974 or 1976-1980, was not observed in later surveys. There was an age gradient in changes in most diet and SES associations over time, with largest adverse changes in 12- to 19-y olds. Higher education was associated with lower energy from snack episodes, breakfast skipping, and energy density of foods and these associations did not change over time. Overall, these results suggest both income and education differentials in secular increases in food amounts and energy intakes.
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. Intake of dairy products, fruits and vegetables was 5.5 (95% CI 2.4-12.5), 1.7 (95% CI 1.1-2.5) and 2.2 (95% CI 1.3-3.5) times higher among those who consumed breakfast daily vs. those who never consumed breakfast. Breakfast consumption was associated with greater physical activity vs. those who never consumed breakfast. Positive values and beliefs about healthy eating; body image

Introduction Environments that facilitate energy-dense, nutrient-poor diets are associated with childhood obesity. We examined the effect of a change of school environment on the prevalence of obesity and related dietary behavior in early adolescence. Methods Fifteen schools in Victoria, Australia, were recruited at random from the bottom 2 strata of a 5-level socioeconomic scale. In 9 schools, students in grade 6 primary school transitioned to different schools for grade 7 secondary school, whereas in 6 schools, students remained in the same school from grade 6 to grade 7. Time 1 measures were collected from students (N = 245) in grade 6 (aged 11–13 y). Time 2 data were collected from 243 (99%) of the original cohort in grade 7. Data collected were dietary recall self-reported by students via questionnaire, measured height and weight of students, and aspects of the school food environment via school staff survey. Comparative and mixed model regression analyses were conducted. Results Of 243 students, 63% (n= 152) changed schools from time 1 to time 2, with no significant difference in weight status. Students who changed schools reported an increase in purchases of after-school snack food, greater sweetened beverage intake, fewer fruit-and-vegetable classroom breaks, and less encouragement for healthy eating compared with students who remained in the same school. School staff surveys showed that more primary than secondary schools had written healthy canteen policies and fewer days of canteen or food services operation. Conclusion A change of school environment has negative effects on children’s obesity-related dietary behavior. Consistent policy is needed across school types to support healthy eating in school environments. PMID:26355826

Dietary components of adolescent obesity interventions are rarely evaluated with comprehensive reporting of dietary change. The objective was to assess dietary change in overweight adolescents, including adherence to dietary intervention. The dietary intervention was part of a multi-component intervention (CAFAP) targeting the physical activity, sedentary and healthy eating behaviors of overweight adolescents (n = 69). CAFAP was a staggered entry, within-subject, waitlist controlled clinical trial with 12 months of follow up. Diet was assessed using three-day food records and a brief eating behavior questionnaire. Changes in dietary outcomes were assessed using linear mixed models, adjusted for underreporting. Food record data suggested reduced adherence to dietary intervention messages over time following the intervention, despite conflicting information from the brief eating behavior questionnaire. During the intervention, energy intake was stable but favorable nutrient changes occurred. During the 12 month maintenance period; self-reported eating behaviors improved, energy intake remained stable but dietary fat and saturated fat intake gradually returned to baseline levels. Discrepancies between outcomes from brief dietary assessment methods and three-day food records show differences between perceived and actual intake, highlighting the need for detailed dietary reporting. Further, adherence to dietary intervention principles reduces over time, indicating a need for better maintenance support.

Weight gain has been associated with behaviors related to diet, sedentary lifestyle, and physical activity. We investigated dietary patterns and possible meaningful clustering of physical activity, sedentary behavior, and sleep time in Spanish children and adolescents and whether the identified clusters could be associated with overweight. Analysis was based on a subsample (n = 415) of the cross-sectional ANIBES study in Spain. We performed exploratory factor analysis and subsequent cluster analysis of dietary patterns, physical activity, sedentary behaviors, and sleep time. Logistic regression analysis was used to explore the association between the cluster solutions and overweight. Factor analysis identified four dietary patterns, one reflecting a profile closer to the traditional Mediterranean diet. Dietary patterns, physical activity behaviors, sedentary behaviors and sleep time on weekdays in Spanish children and adolescents clustered into two different groups. A low physical activity-poorer diet lifestyle pattern, which included a higher proportion of girls, and a high physical activity, low sedentary behavior, longer sleep duration, healthier diet lifestyle pattern. Although increased risk of being overweight was not significant, the Prevalence Ratios (PRs) for the low physical activity-poorer diet lifestyle pattern were >1 in children and in adolescents. The healthier lifestyle pattern included lower proportions of children and adolescents from low socioeconomic status backgrounds. PMID:26729155

To better understand the relation between emotional eating and dietary choices, dietary correlates of emotional eating were investigated in an adolescent sample. Participants were 617 predominantly Latino middle school students from seven schools in Los Angeles County. Analyses of cross-sectional data revealed that emotional eating was associated with increased frequency of intake of sweet high energy-dense foods, such as cake and ice cream, salty high energy-dense foods like chips, and soda. Gender stratified analyses revealed an association between emotional eating and more frequent fruit and vegetable intake in boys only, and a positive association between emotional eating and salty high energy-dense intake in both boys and girls. These data support previous literature that reports a preference for high energy-dense food in emotional eating, and shows that this association may be generalizable to Latino youth. Considering that emotional eating may lead to overeating because it often takes place in the absence of hunger, it may be appropriate to develop interventions to teach youth healthier substitutions and regulate mood by means other than eating in order to reduce risk for obesity, especially in high risk populations, such as Latinos.
As with school age children, it is difficult to make conclusions about the validity of available dietary assessment instruments for adolescents because of the differences in instruments, research designs, reference methods, and populations in the validation literature.

Background Considering both diet and energy expenditures possess some influence on weight status, research into dietary determinants of obesity is challenging but essential to rational planning of well-organized interventions to avoid obesity. Objectives This study aimed to determine whether dietary factors were predictive of overweight and obesity in adolescents in the Iranian population. Patients and Methods A total of 840 students, ages 15 - 17, from six schools were enrolled in this cross-sectional study. A diet-patterns approach often has been used to describe the eating patterns in adolescents. Height, weight, and waist circumference anthropometric indices, physical activity, waist hip ratio, and BMI measurements were determined. Daily dietary data and weighed food records were collected in 2010 and 2011. Abdominal obesity was defined according to world health organization guidelines, and the relationship between dietary predictor variables and the measures of adiposity were determined by using linear regression. Usual dietary intakes were assessed in an experimental study of Esfahani students. Results In total, 38.5% of girls and 32.2% of boys had a Western dietary pattern as the more prevalent pattern. The diet quality of adolescents with the lowest score on each dietary pattern was compared with those recording the highest scores. Those with the Western dietary pattern score were less likely to exercise and had a higher prevalence of general obesity. Adolescents in the greater quartile of the Mediterranean dietary patterns had the lowest odds of being overweight (OR 0.50, 95%; CI 0.27 - 0.73) and obese (OR 0.48, 95%; CI 0.15 - 0.80) than those in the lower quartile, whereas those in the greater quartile of the Western dietary pattern had the highest odds of being overweight (OR 1.69, 95%; CI 1.10 - 2.04) and obese (OR 1.44, 95% CI 1.05 - 1.84). Higher consumption of a Western dietary pattern and a salty dietary pattern were associated significantly with

Dietary supplements use is relatively widespread in some countries but knowledge of supplements consumption in Malaysia is limited, more so among adolescents. This study aimed to investigate the determinants of dietary supplements use among Malaysian adolescents using multiple logistic regressions analysis. Data from the Malaysia School-based Nutrition Survey 2012 based on a 2-stage stratified sampling was used. The prevalence of vitamin/mineral supplements and food supplements intake among adolescents was 54.1% and 40.2%, respectively. Usage was significantly higher among younger adolescents and among boys. Dietary supplements were also taken mostly by those who thought they were underweight. The most common vitamin/mineral supplements and food supplements consumed were vitamin C and bee products. The main reason for taking supplements was parents' instruction. These findings can be useful for developing health communications on supplement use targeted to adolescents and their parents.

Food choices of adolescents are not consistent with the Dietary Guidelines for Americans. Food intakes tend to be low in fruits, vegetables, and calcium-rich foods and high in fat. Skipping meals is also a concern among adolescents, especially girls. Factors influencing eating behaviors of adolescents need to be better understood to develop effective nutrition interventions to change eating behaviors. This article presents a conceptual model based on social cognitive theory and an ecological perspective for understanding factors that influence adolescent eating behaviors and food choices. In this model, adolescent eating behavior is conceptualized as a function of individual and environmental influences. Four levels of influence are described: individual or intrapersonal influences (eg, psychosocial, biological); social environmental or interpersonal (eg, family and peers); physical environmental or community settings (eg, schools, fast food outlets, convenience stores); and macrosystem or societal (eg, mass media, marketing and advertising, social and cultural norms).

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.

Until now, the literatures on the effects of food parenting practices and parents' own dietary behavior on children's dietary behavior have largely been independent from one another. Integrating findings across these areas could provide insight on simultaneous and interacting influences on children's food intake. In this narrative review, we provide a conceptual model that bridges the gap between both literatures and consists of three main hypotheses. First, parental dietary behavior and food parenting practices are important interactive sources of influence on children's dietary behavior and Body Mass Index (BMI). Second, parental influences are importantly mediated by changes in the child's home food environment. Third, parenting context (i.e., parenting styles and differential parental treatment) moderates effects of food parenting practices, whereas child characteristics (i.e., temperament and appetitive traits) mainly moderate effects of the home food environment. Future studies testing (parts of) this conceptual model are needed to inform effective parent-child overweight preventive interventions.

The use of image-based dietary assessment methods shows promise for improving dietary self-report among children. The Technology Assisted Dietary Assessment (TADA) food record application is a self-administered food record specifically designed to address the burden and human error associated with conventional methods of dietary assessment. Users would take images of foods and beverages at all eating occasions using a mobile telephone or mobile device with an integrated camera [e.g. Apple iPhone, Apple iPod Touch (Apple Inc., Cupertino, CA, USA); Nexus One (Google, Mountain View, CA, USA)]. Once the images are taken, the images are transferred to a back-end server for automated analysis. The first step in this process is image analysis (i.e. segmentation, feature extraction and classification), which allows for automated food identification. Portion size estimation is also automated via segmentation and geometric shape template modeling. The results of the automated food identification and volume estimation can be indexed with the Food and Nutrient Database for Dietary Studies to provide a detailed diet analysis for use in epidemiological or intervention studies. Data collected during controlled feeding studies in a camp-like setting have allowed for formative evaluation and validation of the TADA food record application. This review summarises the system design and the evidence-based development of image-based methods for dietary assessment among children.
In the last two decades, the number of new cases of type 2 diabetes mellitus (T2DM) among U.S. adolescents has increased (Fagot-Campagna et al., 2000; SEARCH Study Group, 2006), which may be related to the lack of health-promoting behaviors, such as a balanced diet and adequate physical exercise. This descriptive correlational study examined the relationship between perceived risk for T2DM, dietary intake, and physical activity in adolescents (N = 80) 13 to 18 years of age. The Children's Health Belief Model (Bush & lannotti, 1990) was the conceptual framework used for testing the theoretical relationships. Participants completed the following instruments: 1) Knowledge of Risk Factors for T2DM, 2) Health Beliefs for T2DM, 3) Godin-Shepard Leisure-Time Exercise Questionnaire (Godin & Shepard, 1997), and 4) the Demographic/Medical Questionnaire. Significant relationships were found between perceived risk, a subset of the Health Beliefs for T2DM scale, and the health promoting behaviors of dietary intake and physical activity. Implications for health-promoting nursing practice related to adolescent perception of risk and health-promoting behaviors of dietary intake and physical activity are addressed.

To investigate eating disorder behaviors and attitudes in adolescents, we administered the eating disorder examination questionnaire (EDE-Q) to Japanese adolescent girls and boys. The EDE-Q global scores in Japanese girls and boys, respectively, were significantly lower than those in girls and boys in previous studies. Objective binge eating episodes and extreme dietary restriction were the common behaviors, whereas self-induced vomiting and the misuse of laxatives were uncommon. Differences in the EDE-Q data between Japanese adolescents and adolescents in previous studies from Western countries suggest that there may be certain cultural differences in eating disorder psychopathology in adolescents.

Behaviour therapies using conditioning principles have been successful in the treatment of some psychopatological eating behaviours. Such have been the cases for anorexia nervosae in adolescents and adults, refusal to eat in the young child and difficulties of swallowing. Some of these cases are described. Research has been done in different countries on the applications of these methods to the treatment of obesity caused by overeating which appears very frequently in our societies. Systematic and covert desensitization and operant conditioning using positive reinforcements are more frequently used in these behaviour modification procedures than aversive methods. More recently, researches on self-control (self-reward and self-punishment) have shown it as a very efficient tool for inducing weight loss. These methods using self-control have been applied to large populations: after a first, careful examination of the patient's eating behaviour, the program of reinforcement is established. It can be partially controlled by written instructions and letters. Results are already encouraging although they need to be followed up. But more research should be done on overeating behaviours, the way they appear and are maintained and on different programs of reinforcement for weight loss.

Objective Given the public health importance of improving dietary behavior in chronic disease prevention in low- and middle-income countries it is crucial to understand the factors influencing dietary behavior in these settings. This study tested the validity of a conceptual framework linking individual and environmental factors to dietary behavior among Ecuadorian adolescents aged 10–16 years. Methods A cross-sectional survey was conducted in 784 school-going Ecuadorian adolescents in urban and rural Southern Ecuador. Participants provided data on socio-economic status, anthropometry, dietary behavior and its determining factors. The relationships between individual (perceived benefits and barriers, self-efficacy, habit strength, and a better understanding of healthy food) and environmental factors (physical environment: accessibility to healthy food; social environment: parental permissiveness and school support), and their association with key components of dietary behavior (fruit and vegetables, sugary drinks, breakfast, and unhealthy snack intake) were assessed using structural equation modeling. Results The conceptual model performed well for each component of eating behavior, indicating acceptable goodness-of-fit for both the measurement and structural models. Models for vegetable intake and unhealthy snacking showed significant and direct effects of individual factors (perceived benefits). For breakfast and sugary drink consumption, there was a direct and positive association with socio-environmental factors (school support and parental permissiveness). Access to healthy food was associated indirectly with all eating behaviors (except for sugary drink intake) and this effect operated through socio-environmental (parental permissiveness and school support) and individual factors (perceived benefits). Conclusion Our study demonstrated that key components of adolescents’ dietary behaviors are influenced by a complex interplay of individual and

Mammary tissue experiences the highest rate of proliferation during adolescence representing a period of heightened susceptibility. Few prospective studies have examined adolescent diet and breast cancer, and none have examined dietary patterns. Thus, we examined the association between adolescent dietary patterns and a diet quality index, the Alternative Healthy Eating Index (AHEI), and breast cancer in the Nurses’ Health Study II among those who completed a 124-item food frequency questionnaire about their high-school diet (HS-FFQ). Cox proportional hazards regression models were used to calculate hazard ratios (HR) and 95% confidence intervals (95% CI). Among 45204 women who completed the HS-FFQ, 863 cases of premenopausal breast cancer and 614 cases of postmenopausal cancer were diagnosed. A marginal inverse association was observed between the ‘prudent’ dietary pattern, characterized by high intake of vegetables, fruits, legumes, fish and poultry, and premenopausal breast cancer. Women in fifth quintile had a multivariable adjusted HR (95% CI) of 0.84 (0.67–1.04) for premenopausal breast cancer (P trend = 0.07) compared with the first quintile. Scoring higher on the AHEI was borderline significantly associated with premenopausal breast cancer with a HR of 0.81 (0.64–1.01) for the fifth quintile (P trend = 0.08), and this association appeared to be stronger for estrogen receptor-negative/progesterone receptor-negative tumors. No association was observed between the ‘Western’ pattern or the ‘fast-food’ pattern. Results were similar for each of these patterns when both premenopausal and postmenopausal breast cancer were considered together. An overall healthy diet during adolescence, similar to the prudent dietary pattern or adherence to the AHEI, may contribute to reducing the risk of breast cancer. PMID:26905584

Adolescence is a time of rapid growth and development with biologic, psychological, and emotional changes occurring simultaneously. We conducted a critical review of the literature to analyze key topics in the study of adolescents' eating behaviors and to identify barriers to healthy eating experienced by adolescents. The literature documents that nutritional deficits and poor eating established during adolescence have long-term health, growth, and developmental consequences. Gaps in the literature are identified and recommendations for future studies are proposed.

Animals have evolved diverse behaviors that serve the purpose of finding food in the environment. We investigated the food seeking strategy of the soil bacteria-eating nematode Caenorhabditis elegans. C. elegans bacterial food varies in quality: some species are easy to eat and support worm growth well, while others do not. We show that worms exhibit dietary choice: they hunt for high quality food and leave hard-to-eat bacteria. This food seeking behavior is enhanced in animals that have already experienced good food. When hunting for good food, worms alternate between two modes of locomotion, known as dwelling: movement with frequent stops and reversals; and roaming: straight rapid movement. On good food, roaming is very rare, while on bad food it is common. Using laser ablations and mutant analysis, we show that the AIY neurons serve to extend roaming periods, and are essential for efficient food seeking. PMID:16354781

The aim of this study was to assess dietary intake, breastfeeding history, weight at birth and current weight in children and adolescents with Down syndrome (DS). Therefore, a cross-sectional, controlled study with 19 DS participants and 19 controls without DS matched by gender and age was performed. Except for vitamin D, a lower or the same frequency of insufficient intake in other micronutrients was noted in participants compared with controls. The DS group had a reduced exclusive breastfeeding duration and increased carbohydrate and caloric intake. The consumption of micronutrients in both groups reinforced the current trend of excessive sodium consumption and insufficient intake of calcium, some B complex vitamins and water by children and adolescents.

The assessment of dietary intake in children and adolescents is of great interest for different purposes. The characteristics of each developmental stage and associated cognitive abilities are two factors that influence the ability of children to provide valid and reliable information on food consumption. The ability to remember, limitations of vocabulary or the ability to identify different foods are some of the relevant aspects. In addition, often parents or caregivers provide surrogate information and their degree of knowledge depends on the time they spend with the child and on whether they share meals. As children grow they become more independent and increasingly spend more time away from their parents. Children also have limitations to recognize food models and photographs and associate them with different amounts of food consumed. On the other hand, often children and adolescents perceive long interviews or self-administered questionnaires they as long and boring. The use of new technologies is contributing to the development of new tools adapting dietary assessment the methods to the cognitive abilities of children, introducing gaming environments and narrative structures that attract their interest and improve the quality of information they report..

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

The study aimed to explore how both sex and dietary restraint impacts brain activation in response to visual food stimuli in young adolescents (12-13 years) under fed and fasted conditions. Food and non-food images were viewed by 15 boys and 14 girls, while functional magnetic resonance images were acquired. The adolescents were either fasted or in a satiated (fed) state following a randomized crossover study design. When satiation state was not considered, girls showed significantly greater brain activity than boys in regions associated with executive function and decision making, working memory, and self-awareness. In contrast, when either fasted or fed states were considered separately, boys showed significantly increased brain activity in regions linked to executive function, self-awareness, and decision making than the girls. When fasted, compared to unrestrained eaters, restrained individuals showed heightened activation in regions connected to executive function and decision making, with areas associated with self-assessment showing increased activity for unrestrained eaters relative to restrained under fed conditions. These findings highlight important differences in adolescent brain activity and support further investigations to gain greater insight into how these differences might evolve with age.

Seventy percent of Mexican households experience some level of food insecurity (FI). Studies have shown positive associations between FI and poor dietary quality. As far as it is known, this is the first time the Healthy Eating Index (HEI-2010) has been used to assess dietary quality of children and adolescents in Mexico, and to examine if FI is related to it. The objective of this research is to assess dietary quality and its association with FI among Mexican children and adolescents from a nationally representative cross-sectional sample. We analyzed data from 4635 2-19-year-old Mexican children and adolescents participating in the Mexican National Health and Nutrition Survey (Ensanut 2012). FI was measured using the Latin American and Caribbean Household Food Security Scale (ELCSA) and dietary quality with the HEI-2010. We examined the association between FI and dietary quality using multivariate linear regressions. Dietary quality was worst as FI became more severe among children and adolescents compared with their counterparts living in households with food security. Specifically, FI had a negative association with fruits, vegetables, and protein foods, and a positive association with refined grains consumption. Dairy intake was negatively associated with FI among older children and adolescents. Added sugars were not associated with FI, but intake was excessive across the population at 15% of total daily energy intake. Decreasing FI may help improve dietary quality of Mexican children and adolescents.

Purpose Vitamin D may reduce cell proliferation and tumor growth in breast tissue, and exposure may be most important during adolescence when breast tissue is developing. In the Nurses’ Health Study II, higher recalled adolescent vitamin D intake was associated with a lower risk of benign breast disease (BBD). Our study aim was to assess adolescent vitamin D exposure in relation to BBD in young women. Methods Vitamin D was assessed in 6,593 adolescent girls (9 to 15 years of age at baseline) in the prospective Growing Up Today Study cohort using the mean energy-adjusted intakes from food frequency questionnaires in 1996, 1997, and 1998. In 1999, 5286 girls reported skin color, sunscreen use, tanning bed use, and number of sunburns in the past year, and we used state of residence to assess low vs. high ultraviolet (UV) index. Biopsy-confirmed BBD was reported on questionnaires in 2005, 2007, and 2010 (n=122). Results Dietary vitamin D, tanning behaviors, and other sun exposure variables were not significantly associated with BBD in logistic regression models adjusted for age, family history of breast cancer or BBD, age at menarche, nulliparity, alcohol intake, body mass index, and physical activity. The relative risk for the top (>467 IU/day) vs. bottom (<243 IU/day) quartile of vitamin D intake was 0.76 (95% CI: 0.47, 1.23). Conclusions Sun exposure was not significantly associated with BBD in this prospective cohort study. However, a suggestive inverse association between dietary vitamin D and BBD was observed that merits further study. PMID:26084210

Introduction Celiac disease (CD) is caused due to intake of gluten, a protein component in wheat, barley, and rye. The only treatment currently available for CD is strict lifetime adherence to a gluten-free diet (GFD) which is a diet that excludes wheat, barley, and rye. There is limited information on barriers to following a GFD. The present study aimed to investigate the compliance with a GFD, barriers to compliance, and the impact of compliance on the quality of life (QOL) in Iranian children and adolescents suffering from CD. Methods In this cross-sectional study, a total of 65 known cases of CD (both males and females), diagnosed in Namazi Hospital, a large referral center in south of Iran, selected by census were studied in 2014. Dietary compliance was assessed using a questionnaire. A disease-specific QOL questionnaire for children with CD (the celiac disease DUX [CDDUX]) was used. Comparisons between categorical variables were performed using chi-square test. Results Sixty-five patients, 38 females (58.5%) and 27 (41.5%) males, were surveyed. Mean (± standard deviation [SD]) age of the respondents was 11.3 (±3.8) years. Dietary compliance was reported by 35 (53.8%) patients. The mean (± SD) CDDUX score was higher in dietary-compliant patients (33.5 [±19.4] vs 26.7 [±13.6], respectively, P=0.23). The score of CDDUX in parents of patients in dietary-compliant group was more than the noncompliant patients (28.1 [±13.5] vs 22.1 [±14], respectively, P=0.1). Barriers to noncompliance were poor or unavailability (100%), high cost (96.9%), insufficient labeling (84.6%), poor palatability (76.9%), and no information (69.23%). Conclusion Approximately half of the patients with CD reported dietary compliance. Poor or unavailability was found to be the most important barrier contributing to noncompliance. The QOL was better in compliant patients. Proposed strategies to improve compliance are greater availability of gluten-free products, better food labeling, and

Impulsivity is a multifaceted construct that defines a range of maladaptive behavioral styles. The present research aimed to identify different dimensions of impulsive behavior in adolescents from a battery of laboratory behavioral assessments. In one analysis, correlations were examined between two self report and seven laboratory behavioral measures of impulsivity. The correlation between the two self report measures was high compared to correlations between the self report and laboratory behavioral measures. In a second analysis, a principal components analysis was performed with just the laboratory behavioral measures. Three behavioral dimensions were identified -- "impulsive decision-making", "impulsive inattention", and "impulsive disinhibition". These dimensions were further evaluated using the same sample with a confirmatory factor analysis, which did support the hypothesis that these are significant and independent dimensions of impulsivity. This research indicates there are at least three separate subtypes of impulsive behavior when using laboratory behavioral assessments with adolescent participants.

Objective To examine associations between young adults’ dietary behaviors and perceived social norms for healthy eating. Methods Cross-sectional survey of 1000 diverse college students. Associations between perceived behaviors of family, friends, and significant other and participants’ dietary behaviors were examined using t-tests and linear regressions. Results Young adults consumed more fast food if they perceived that their family, friends, or significant other did so (p < .003). Sugar-sweetened beverage consumption was associated with perceived consumption by family and friends (p < .034). Fruit and vegetable consumption and dinner preparation were associated with perceived behavior of friends only (p < .001). Conclusions Young adults’ dietary behaviors appear to reflect their perceptions of normative behavior, particularly among friends. PMID:24034689

Context: Multiple studies have been conducted on correlates of dietary behavior in adults, but a clear overview is currently lacking. Objective: An umbrella review, or review-of-reviews, was conducted to summarize and synthesize the scientific evidence on correlates and determinants of dietary behavior in adults. Data Sources: Eligible systematic reviews were identified in four databases: PubMed, PsycINFO, The Cochrane Library, and Web of Science. Only reviews published between January 1990 and May 2014 were included. Study Selection: Systematic reviews of observable food and dietary behavior that describe potential behavioral determinants of dietary behavior in adults were included. After independent selection of potentially relevant reviews by two authors, a total of 14 reviews were considered eligible. Data Extraction: For data extraction, the importance of determinants, the strength of the evidence, and the methodological quality of the eligible reviews were evaluated. Multiple observers conducted the data extraction independently. Data Synthesis: Social-cognitive determinants and environmental determinants (mainly the social-cultural environment) were included most often in the available reviews. Sedentary behavior and habit strength were consistently identified as important correlates of dietary behavior. Other correlates and potential determinants of dietary behavior, such as motivational regulation, shift work, and the political environment, have been studied in relatively few studies, but results are promising. Conclusions: The multitude of studies conducted on correlates of dietary behavior provides mixed, but sometimes quite convincing, evidence. However, because of the generally weak research design of the studies covered in the available reviews, the evidence for true determinants is suggestive, at best. PMID:26106126
Mobile technologies are emerging as a valuable tool to collect and assess dietary intake. Adolescents readily accept and adopt new technologies, hence, a food record application (FRapp) may provide an accurate mechanism to monitor dietary intake. We examined the usability of a FRapp in 17 free-livin...

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.

The major morbidities and mortalities of adolescents are related to preventable risky behaviors, but how, when, and in whom these behaviors develop in early adolescence is unknown. The purpose of this study was to determine which set of risk factors and protective resources of school-age children were best predictors of health-risk behaviors in early adolescence. A longitudinal, cohort sequential design was used with a diverse sample of 1,934 children in grades 4 through 8. Parents provided demographic and neighborhood data for children through a mailed survey. Children completed valid scales annually at schools, using audio-computer-assisted self-interviewing (A-CASI) technology. Significant gender and racial/ethnic differences were found in carrying a weapon and using alcohol. Higher perceived levels of stress increased the risk for alcohol use as did riding in a car with a driver who was drinking. Health behaviors exhibited while in 4th through 6th grades protected early adolescents from alcohol use and riding in a car with a driver who was drinking. A parent's education and perceived safety in neighborhood protected against carrying a weapon and smoking. Many findings are similar to those of national samples, but others show positive differences in this localized sample, over 50% of whom were Latino. Protective resources suggest numerous nursing interventions to promote healthy adolescent development.

The aim of this paper is to assess the possible consequences of adolescent physical, emotional and sexual dating violence through a review of the literature on the topic. An electronic search of major biomedical bibliographic databases (Pubmed, ISI, PsycINFO) was used to retrieve articles providing information on the prevalence rates, risk factors, associated consequences and possible preventive measures for adolescent dating violence across different populations. Currently, there have been few longitudinal studies conducted to identify potential risk factors for entering a violent dating relationship in adolescence. Risky behaviors such as early sexual intercourse may predispose someone for victimization. Dating violence itself is also a predictor of future dating violence. Adolescent dating violence was associated with an increase in other violence-related behaviors, substance use, depression, poorer educational outcomes, posttraumatic stress, unhealthy weight control and risky sexual behavior. The association between adolescent dating violence and an increase in suicidal behavior is a major public health concern. Future research should focus on longitudinal studies so that a causal relationship between dating violence and suicidality may be better understood.

Objective Early maturing girls are at increased risk for disordered eating. However, it is unclear if the association between puberty and disordered eating continues throughout pubertal development and if a similar association is exhibited in boys. Method Participants included 1340 same- and 624 opposite-sex twins from the Swedish Twin Study of Child and Adolescent Development. Pubertal development was assessed at age 13–14 with the Pubertal Development Scale. General disordered eating, measured with the Eating Disorder Inventory-2 (EDI) was assessed at age 16–17, and dieting and purging behaviors were assessed at both ages 16–17 and 19–20. We applied analysis of variance and logistic regression analyses to determine whether pubertal development in early-to-mid adolescence predicted eating disorder-related behaviors in late adolescence and young adulthood Results Pubertal development in early-to-mid adolescence was significantly associated with EDI scores and dieting in late adolescence. No significant association was observed between pubertal development and dieting and purging in young adulthood. Discussion Complex combinations of cultural and biological influences likely converge during pubertal development increasing vulnerability to disordered eating. The impact of pubertal development on disordered eating appears to be limited to the adolescent period. PMID:22522282

Obese people tend to have low zinc circulation levels; this is not always related to zinc intake but can reflect the distribution of zinc in relation to the proportion of body fat and factors related to the inflammatory processes that cause obesity. The purpose of this study was to assess zinc distribution in 15 obese adolescent girls before and after a nutritional orientation program. Participants ranged from 14 to 18 years old (postpubescent) and had a body fat percent (BF%) of >35 %. Zinc nutritional status and other zinc-dependent parameters, such as superoxide dismutase (SOD) and insulin levels, were assessed by biochemical analysis of plasma and erythrocytes, salivary sediment, and urine. Samples were collected before and after 4 months of dietary intervention. Dual energy X-ray absorptiometry (DXA) was used to verify BF% both at the beginning and at the end of the study. Food consumption was assessed in ten individual food questionnaires throughout the study; food groups were separated on the questionnaires in the same way as suggested by some authors to develop the Healthy Eating Index (HEI) but with the addition of zinc. After 4 months of nutritional orientation, 78 % of the participants showed a decrease in BF%. Intraerythrocytic zinc increased over the study period, while salivary sediment zinc, SOD, insulin, and Zn urinary24 h/creatinine all decreased (p < 0.05). There was no difference in zinc intake throughout the study but participants did increase their consumption of fruits, dairy, and meats during the study (p < 0.05). There were inverse and statistically significant correlations between the increased levels of intraerythrocytic zinc and decreased levels of SOD. There was also a statistically significant correlation between BF% and Zn urinary 24h/creatinine, and SOD. All these parameters were diminished at the end of the study. The dietary intervention for obese adolescent girls is effective with decrease of BF that led to the

Data suggest that depressed affect and dietary restraint are related to disinhibited eating patterns in children and adults. Yet, experimental research has not determined to what extent depressed affect acutely affects eating in the absence of physiological hunger (EAH) in adolescents. In the current between-subjects experimental study, we measured EAH in 182 adolescent (13-17y) girls (65%) and boys as ad libitum palatable snack food intake after youth ate to satiety from a buffet meal. Just prior to EAH, participants were randomly assigned to view either a sad or neutral film clip. Dietary restraint was measured with the Eating Disorder Examination. Adolescents who viewed the sad film clip reported small but significant increases in state depressed affect relative to adolescents who viewed the neutral film clip (p < .001). Yet, there was no main effect of film condition on EAH (p = .26). Instead, dietary restraint predicted greater EAH among girls, but not boys (p < .001). These findings provide evidence that adolescent girls’ propensity to report restrained eating is associated with their greater disinhibited eating in the laboratory. Additional experimental research, perhaps utilizing a more potent laboratory stressor and manipulating both affective state and dietary restraint, is required to elucidate how state affect may interact with dietary restraint to influence EAH during adolescence.

Evidence has grown supporting the role for short sleep duration as an independent risk factor for weight gain and obesity. The purpose of the present study was to examine the relationship between sleep duration and dietary quality in European adolescents. The sample consisted of 1522 adolescents (aged 12.5-17.5 years) participating in the European multi-centre cross-sectional ‘Healthy Lifestyle in Europe by Nutrition in Adolescence’ study. Sleep duration was estimated by a self-reported questionnaire. Dietary intake was assessed by two 24 h recalls. The Diet Quality Index for Adolescents with Meal index (DQI-AM) was used to calculate overall dietary quality, considering the components dietary equilibrium, dietary diversity, dietary quality and a meal index. An average sleep duration of ≥ 9 h was classified as optimal, between 8 and 9 h as borderline insufficient and < 8 h as insufficient. Sleep duration and the DQI-AM score were positively associated (β = 0.027, r 0.130, P< 0.001). Adolescents with insufficient (62.05 (sd 14.18)) and borderline insufficient sleep (64.25 (sd 12.87)) scored lower on the DQI-AM than adolescents with an optimal sleep duration (64.57 (sd 12.39)) (P< 0.001; P= 0.018). The present study demonstrated in European adolescents that short sleep duration was associated with a lower dietary quality. This supports the hypothesis that the health consequences of insufficient sleep may be mediated by the relationship of insufficient sleep to poor dietary quality.

Despite the prevalence of suicidal thoughts and behaviors among adolescents, there is limited knowledge of effective interventions to use with this population. This paper reviews the findings of studies on behavioral interventions for adolescents who are at acute suicide risk, as well as outpatient treatment and risk management strategies with suicidal adolescents. The importance of addressing comorbid behaviors and enhancing protective factors are discussed. Cultural considerations in working with suicidal adolescents and strategies for conducting culturally competent treatment are explored. PMID:26279646

Although most adopted children are well adjusted, research has consistently found that adopted adolescents are at an increased risk for externalizing behaviors. The present investigation tested a model whereby parent-adolescent negative emotionality traits, adolescent conflict, and adoption status contribute to adolescent externalizing behaviors. The study included 616 families with at least one parent and two adolescent siblings with a maximum 5-year age difference. The analyses used data from the mothers (M age = 45.56, SD = 4.23), fathers (M age = 48.23, SD = 4.42), and the elder sibling (M age = 16.14, SD = 1.5). Findings support two conflict-mediated family processes that contributed to externalizing behaviors: one initiated by parent-adolescent traits and one by adoption status. Findings also underscore the salience of conflict in families and the significance of aggressive traits and negative emotionality. Contrary to previous research, we found that adoption status did not directly add to our explanation of adolescent externalizing behaviors beyond our proposed process. Instead, adoption status was indirectly associated with externalizing problems through a conflict-mediated relationship.

Food literacy has been identified as a promising approach to support healthy dietary behaviours in adolescents. However, adolescents' perspectives on food literacy and the impact it could have on their dietary behaviours are not well understood. This study explored adolescents' perspectives on the potential for food literacy to influence their dietary behaviours. Fifteen focus groups were conducted with adolescents aged 12-17 years and encompassed quantitative and qualitative questions. Adolescents were asked to rank 22 aspects of food literacy in order of importance and discuss their responses as a group. Overall, adolescents ranked food and nutrition knowledge as more important than food skills and food capacity. Although adolescents stated that food and nutrition knowledge is important for them to eat well, the majority did not apply their knowledge to practice due to low confidence in food skills. Participants demonstrated very limited knowledge about macro aspects of food literacy such as animal welfare or environmental sustainability. Food skills such as planning and managing budgets for food and time for food shopping were ranked as least important due to being presently irrelevant but recognised as important later in life. Adolescents reported being very interested in developing food skills such as food preparation but they had very limited opportunities due to lack of food literacy education in home and high school settings. The high school setting provides an ideal opportunity for adolescents to improve their food literacy in particular food skills through home economics. Future research should develop and measure adolescents' food literacy and its impact on their dietary behaviours.

Several studies suggest that dietary habits are associated with poor academic performance. However, few studies have evaluated these relations after adjusting for numerous confounding factors. This study evaluated the frequency of various diet items (fruit, soft drinks, fast foods, instant noodles, confections, vegetables, and milk) and the regularity of meal times (breakfast, lunch, and dinner) all at once.A total of 359,264 participants aged from 12 to 18 years old were pooled from the Korea Youth Risk Behavior Web-based Survey (KYRBWS) for the 2009 to 2013 period. Dietary habits over the last 7 days were surveyed, including the regularity of consuming breakfast, lunch and dinner and the frequency of eating fruits, soft drinks, fast foods, instant noodles, confections, vegetables, and milk. Physical activity, obesity, region of residence, subjective assessment of health, stress level, economic level, and parental education level were collected from all of the study participants. School performance was classified into 5 levels. The adjusted odds ratios (AORs) of dietary habits for school performance were analyzed using multinomial logistic regression analyses with complex sampling. Structural equation modeling was used to analyze the effects of diet factors on school performance while considering the effects of other variables on both diet factors and school performance.Frequent intakes of breakfast (AOR = 2.34, 95% confidence interval [CI] = 2.20-2.48), fruits (AOR = 1.73, 95% CI = 1.62-1.86), vegetables (AOR = 1.48, 95% CI = 1.37-1.61), and milk (AOR = 1.35, 95% CI = 1.28-1.43) were related to high levels of school performance (each with P < 0.001). In contrast, soft drinks (AOR = 0.42, 95% CI = 0.38-0.46), instant noodles (AOR = 0.62, 95% CI = 0.55-0.70), fast food (AOR = 0.83, 95% CI = 0.72-0.96), and confectionary (AOR = 0.86, 95% CI = 0.80-0.93) were negatively associated with school

The present study investigated the association between cardiorespiratory fitness (CRF) and dietary intake in European adolescents. The study comprised 1492 adolescents (770 females) from eight European cities participating in the HELENA (Healthy Lifestyle in Europe by Nutrition in Adolescence) study. CRF was assessed by the 20 m shuttle run test. Adolescents were grouped into low and high CRF levels according to the FITNESSGRAM Standards. Dietary intake was self-registered by the adolescents using a computer-based tool for 24 h dietary recalls (HELENA-Dietary Assessment Tool) on two non-consecutive days. Weight and height were measured, and BMI was calculated. Higher CRF was associated with higher total energy intake in boys (P = 0·003). No association was found between CRF and macronutrient intake (as percentage of energy), yet some positive associations were found with daily intake of bread/cereals in boys and dairy products in both boys and girls (all P < 0·003), regardless of centre, age and BMI. CRF was inversely related to sweetened beverage consumption in girls. These findings were overall consistent when CRF was analysed according to the FITNESSGRAM categories (high/low CRF). A high CRF was not related to compliance with dietary recommendations, except for sweetened beverages in girls (P = 0·002). In conclusion, a high CRF is associated with a higher intake of dairy products and bread/cereals, and a lower consumption of sweetened beverages, regardless of centre, age and BMI. The present findings contribute to the understanding of the relationships between dietary factors and physiological health indicators such as CRF.

Young female offenders (n = 29) and female high school students (n = 47) were compared in terms of delinquent behavior and relationships with their best female friend and peer group. Young offenders exhibited significantly more delinquent behavior than did high school students in the past year. Delinquents and nondelinquents did not significantly differ in amount of companionship, conflict, help, security, and closeness with their best female friend, and amount of trust, alienation, and perceived intimacy in their peer group. Less communication and more perceived peer pressure in the peer group distinguished delinquent females from nondelinquent females. Perceived peer pressure significantly predicted delinquent behavior in female adolescents. In short, friendships of delinquent and nondelinquent female adolescents are essentially similar despite higher levels of peer pressure among delinquents.

Although most adopted children are well adjusted, decades of descriptive research have consistently found that adopted adolescents are at an increased risk for externalizing behaviors. Yet we have little understanding of the specific contributing factors that help explain this increased risk. Therefore, the present investigation tested a process model whereby parent-adolescent negative emotionality traits, adolescent conflict, and adoption status contribute to adolescent externalizing behaviors. The study included 616 families from the Sibling Interaction and Behavior Study (SIBS; McGue et al., 2007). The proposed model was tested using Structural Equation Modeling (SEM). Findings support two conflict-mediated family processes that contributed to externalizing behaviors: one initiated by parent-adolescent traits, and one by adoption status. Findings also underscore the salience of conflict in families and the significance of aggressive traits over the other lower order traits (alienation, stress reactivity) and higher order negative emotionality in our proposed process. Contrary to previous research, we found that adoption status did not directly add to our explanation of adolescent externalizing behaviors beyond our proposed process. Instead, adoption status was indirectly associated with externalizing problems through a conflict-mediated relationship. PMID:22023274

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

Dietary fluid and sodium intake may influence the risk for vasoocclusive events in persons with sickle cell anemia (SCA). The objective of this study was to examine the dietary intake of water and sodium in children and adolescents with SCA and identify possible factors influencing intake. We compared water (mL) and sodium (mg) intake in 21 patients with SCA, aged 5 to 18 years, to reported adequate intake for water, daily fluid requirement, upper limit for sodium, and National Health and Nutrition Examination Survey 2005 to 2006 data for sodium, and sociodemographic factors. Dietary intake from 3-day food records was evaluated retrospectively. Median water intake was significantly lower than adequate intake, and median sodium intake was significantly higher than sodium upper limit. Sociodemographic factors were not associated with dietary water or sodium intake. Our results suggest that children and adolescents with SCA would benefit from education regarding increasing fluid intake and limiting high sodium foods.

In order to assess the frequency and correlates of self-injurious behavior (SIB), 569 Portuguese adolescents aged 12 to 20 years completed questionnaires assessing SIB and psychopathological symptoms. Almost 28% (n = 158) reported a lifetime history of SIB and nearly 10% had performed it in the previous month. The most frequently injured body parts were arms, hands and nails. Most of the self-injurers admit that "now and then" they feel some "mild" to "moderate" pain during SIB. Most of them admitted using these behaviors to avoid/suppress negative feelings, painful images or memories, to punish themselves and to avoid doing something bad. Positive emotions increased significantly after SIB. The self-injurer group reported more psychopathological symptoms. SIB appears to be a common phenomenon with specific functions in adolescence and this must be addressed by clinicians and educational professionals.

Background. Physical activity (PA), sedentary behaviors, and dietary behaviors are each associated with overweight and obesity among youth. However, the associations of PA and sedentary behaviors with dietary behaviors are complex and not well understood. Purpose. To describe the associations of PA and sedentary behaviors with dietary behaviors among a representative sample of US high school students. Methods. We analyzed data from the 2010 National Youth Physical Activity and Nutrition Study (NYPANS). Using logistic regression models which controlled for sex, race/ethnicity, grade, body weight status, and weight management goals, we compared dietary behaviors among students who did and did not meet national recommendations for PA and sedentary behaviors. Results. Students who participated in recommended levels of daily PA (DPA) and muscle strengthening PA (MSPA) were more likely than those who did not to eat fruits and vegetables. Students who exceeded recommended limits for television (TV) and computer/video game (C/VG) screen time were less likely than those who did not to consume fruits and vegetables and were more likely to consume fast food and sugar-sweetened beverages. Conclusions. Researchers may want to address PA, sedentary behaviors, and dietary behaviors jointly when developing health promotion and obesity prevention programs for youth. PMID:26101666

This study examined the relationship among dieting, eating attitudes, social physique anxiety, and fruit and vegetable consumption among Turkish adolescents. Abnormal eating behavior (EAT-26 > or =20) was found in 32.8% of the total sample; this included 26.4% of the males and 38.7% of the females. Weight-control and weight-related behaviors are associated with high fruit and vegetable consumption in adolescents. Dieting was significantly associated with types of consumption in female adolescents. In addition, EAT-26 scores were significantly positively correlated with high fruit and vegetable consumption, but this association was not observed in SPAS scores among adolescents. Adolescents who engage in dieting behaviors seem to consume more fruit and vegetables than do other adolescents. Female adolescents may be more likely to display abnormal eating attitudes and dieting behaviors than do males. Although some weight-control behaviors may be risky, adolescents who were practicing dieting behaviors engaged in the positive dietary behavior of consuming more servings of fruit and vegetables than did non-dieters.

Using a large contemporary data set, the National Longitudinal Survey of Youth-Child Supplement (NLSY-CS), this paper examines the effects of parental work schedules on adolescent risky behaviors at age 13 or 14 and the mechanisms that might explain them. Structural equation modeling suggests mothers who worked more often at night spent significantly less time with children and had lower quality home environments, and these mediators were significantly linked to adolescent risky behaviors. Similar effects were not found for evening work schedules, while other types of maternal and paternal nonstandard work schedules were linked to higher parental knowledge of children’s whereabouts, which led to lower levels of adolescent risky behaviors. Subgroup analyses revealed that males, those in families with low incomes, and those whose mothers never worked at professional jobs may particularly be affected by mothers working at nights, due to spending less time together, having a lower degree of maternal closeness, and experiencing lower quality home environments. In addition, the effects of maternal night shifts were particularly pronounced if children were in the preschool or middle-childhood years when their mothers worked those schedules. Implications and avenues for future research are discussed. PMID:20822236

Abstract Objective: To identify dietary patterns of children and to verify their association with socio-economical, behavioral and maternal determinants. Methods: A cross-sectional study with a random sample of 328 children aged 8 and 9 years. Dietary intake was assessed by food records in three nonconsecutive days and measured in grams of food groups and nutrients. Factor analysis and subsequent orthogonal rotation (varimax) were used to determine dietary patterns. Ordinal logistic regression was used to assess associations between dietary patterns and the studied determinants. Results: Five dietary patterns were observed: “Traditional,” “Sweetened beverages and snacks,” “Monotonous,” “Healthy” and “Egg-dairy.” A higher maternal level of education was directly associated with “Sweetened beverages and snacks” and “Egg-dairy' standards. Low income children who were submitted to greater food restriction by parents/guardians followed the more “Traditional” standard, represented by the consumption of rice, beans, vegetables, cooked roots and tubers and red meat. The “Monotonous” pattern, represented by a high consumption of milk and chocolate powder, was most followed by children from the middle class. Children living in rural areas consumed more foods from the “Egg-dairy” pattern, when compared to those from the urban area. Conclusions: Dietary patterns of children were associated with family socioeconomic status, maternal level of education, practice of food restriction by parents/guardians and location of residence in urban or rural area. Better socioeconomic conditions contributed to a more nutritionally inadequate dietary pattern. PMID:26163945

The aim of this study was to describe some characteristics of vaginal, anal and oral sexual behavior in Spanish adolescents. It was a cross-sectional descriptive population study conducted using a probabilistic sample survey. The sample was composed of 4,612 male and female adolescents, of whom 1,686 reported having penetrative sexual experience. Sample size was established with a 97% confidence level and a 3% estimation error. Data collection took place in secondary education schools. Mean age of vaginal sex initiation was 15 years. Compared to females, males reported an earlier age of anal and oral sex initiation and a larger number of vaginal and anal sexual partners. Males also reported a higher frequency of penetrative sexual relations under the influence of alcohol or other drugs. A higher percentage of females than males reported not using a condom in their first anal sexual experience. This study provides a current overview of the sexual behavior of adolescents that can be useful for the design of future programs aimed at preventing HIV and sexually transmitted infections (STIs).

The aim of this study is to describe some characteristics of the sexual behavior of adolescents in Spain and to compare these characteristics according to gender, using a cross-sectional survey. Participants were 1.279 male and female adolescents who reported having had sexual intercourse. A questionnaire about sexual behavior was applied at their high schools and during school hours. Data were collected between 2006 and 2007. Mean age at the onset of sexual intercourse was 14.8 years in males and 15.0 years in females. Males and females were different according to the type of partner at the last sexual intercourse: 63.0% of males had a steady partner compared to 90.5% of females (p < 0.01). The mean number of sexual partners during the last 12 months was higher in males than in females (M = 2.1 and M = 1.5 partners, for males and females, respectively, p < 0.01). 50.0% of males had sexual intercourse under the effects of drugs versus 39.3% of females (p < 0.01). STD and HIV prevention programs should be designed considering the differences according to adolescents' sex.

BACKGROUND/OBJECTIVES Dietary behavior and life stress in adolescence is related to growth rate and learning ability. This study was conducted to identify the relations between dietary habits, dietary attitude nutritional knowledge and life stress among high school girls in Korea and China. SUBJECTS/METHODS The subjects of this study were 221 high school girls in Korea and 227 high school girls in China. The questionnaire were about dietary habits, dietary attitude, nutritional knowledge and life stress. RESULTS The dietary habits of chinese girls were healthier than those of Korean girls with a significant difference (P < .001). There was no significant difference in dietary attitude between Korean girls and Chinese girls. Korean girls had more nutritional knowledge than Chinese girls with a significant difference (P < .001). Korean girls did less physical exercise but spent more time watching TV and using PCs, compared to Chinese girls. Korean girls' degree of confidence in nutrition information that they had learned and their performance in their real lives were low. Also, they had a low level of awareness of the need for nutritional education. There was no significant difference in life stress between the two groups. Dietary habits had a significantly negative correlation with life stress in both Korean and Chinese girls (P < .01, P < .001). As for Chinese students, dietary attitude had a negative correlation with life stress with a significant difference (P < .05). As for Korean girls, nutritional knowledge had a negative correlation with life stress with a significant difference (P < .05), which means as life stress was less, dietary habits were better. CONCLUSIONS This study shows that effective nutrition education programs should include components that encourage application of learned nutrition information to real life, increase physical exercise and reduce life stress.

Background. Adolescents are prone to various forms of behavioral problems. These behavioral issues in adolescents can have serious consequences for the adolescents. Objectives. The objectives of the study are to determine the causative factors of adolescent problems and specific manifestations. Methods. Behavioral problems were investigated using a random sampling of adolescents from secondary schools in southeast Nigeria from February to April, 2014. A self-administered questionnaire was developed from Health Kids Colorado Questionnaire. Results. A total of 763 subjects completed the questionnaire. Adolescents who reported to have used tobacco 3 to 5 and 6 to 9 times during the last 30 days are just 3.14% and 3.4%, respectively. Nineteen (2.49%) adolescents claimed that they have had sex before but not in the last 3 months. Adolescents who attempted suicide are from 15 years and peaked at 18. Eighty-three (11%) adolescents who are 15 years old attempted suicide in a year; this peaks at 17 years where 235 (30.8%) committed suicide. Majority of adolescents with behavioral disorder are from the upper class family. Conclusion. This study revealed that adolescents exhibit several forms of behavioral problems. PMID:25276048

The present study examined differences in dietary habits and physical activity levels between students attending private and public high schools in Jordan. A total of 386 secondary-school males and 349 females aged 14-18 years were randomly recruited using a multistage, stratified, cluster sampling technique. Dietary habits and physical activity level were self-reported in a validated questionnaire. The prevalence of obesity was significantly higher among adolescents in private (26.0%) than in public schools (16.7%). The frequency of breakfast intake was significantly higher among adolescents in private schools, whereas French fries and sweets intake was significantly higher in public schools. Television viewing showed a significant interaction with school type by sex. A higher rate of inactivity was found among students attending private schools. Despite a slightly better overall dietary profile for students in private schools, they had a higher rate of overweight and obesity compared with those in public schools.

The study investigates the prevalence of overweight and obesity in a population of intellectually disabled (ID) adolescents. An observational study was conducted on a group of 410 ID children, living in France. Overweight and obesity, defined according to international standards, were analyzed and related to demographic and sociological parameters, educational care, physical activity and dietary habits. The study highlighted a high prevalence of overweight and obesity (19.0%) in ID adolescents and 22.5% in oldest teenagers, age 15-20 y. This observation was more likely in medico-educative institutes (25.1%) than in general schools (12.3%). Average time spent in physical activity was 4.5 h/week, compared with 3.5 h/week in obese subjects. Time spent in sedentary behavior was 26.6 h/week for the whole population, compared with 18.6 h/week in obese adolescents. Meals were ingested regularly, and adherence to eating breakfast was good. However, snacks and soft drinks were consumed between and during meals by 66.5% of subjects. Overweight in young ID appeared to be related to parental overweight. Even though ID adolescents receive a balanced diet and practice sport regularly, they exhibit a high prevalence for overweight and obesity. In subjects more than 15 years of age, enrollment in medico-educative institutes and parental overweight were contributory factors to poor weight status.

The aim of this study was to investigate cross-sectional associations between dietary patterns and academic performance among 14-year-old adolescents. Study participants were from the Western Australian Pregnancy Cohort (Raine) Study. A food frequency questionnaire was administered when the adolescents were 14 years old, and from the dietary data, a ‘Healthy’ and a ‘Western’ dietary pattern were identified by factor analysis. The Western Australian Literacy and Numeracy Assessment (WALNA) results from grade nine (age 14) were linked to the Raine Study data by The Western Australian Data Linkage Branch. Associations between the dietary patterns and the WALNA (mathematics, reading and writing scores) were assessed using multivariate linear regression models adjusting for family and socioeconomic characteristics. Complete data on dietary patterns, academic performance and covariates were available for individuals across the different analyses as follows: n = 779 for mathematics, n = 741 for reading and n = 470 for writing. Following adjustment, significant negative associations between the ‘Western’ dietary pattern and test scores for mathematics (β = −13.14; 95% CI: −24.57; −1.76); p = 0.024) and reading (β = −19.16; 95% CI: −29.85; −8.47; p ≤ 0.001) were observed. A similar trend was found with respect to writing (β = −17.28; 95% CI: −35.74; 1.18; p = 0.066). ANOVA showed significant trends in estimated means of academic scores across quartiles for both the Western and Healthy patterns. Higher scores for the ‘Western’ dietary pattern are associated with poorer academic performance in adolescence. PMID:25898417

In the USA, suicide ranked as the third leading cause of death for adolescents in 1999. Non-fatal suicidal behaviours are suicidal thought, specific suicidal plan and suicide attempt. Prospective studies have emphasized the high subsequent suicide rates in clinically presenting suicide attempters. This study was planned to critically review the existing international literature on this area, and compare, if possible, with the Indian data. Both electronic and manual search for published and unpublished works was done for the review of this area. Both international and Indian studies on prevalence, risk factors, management, and prevention of non-fatal suicidal behaviours in adolescents were collected, analysed and reviewed. The study concludes that professionals, like general practitioners, paediatricians, school teachers, school counselors, need to be trained in identifying non-fatal suicidal behaviours in adolescents, and know when to refer them to a mental health professional or mental health service for thorough assessment and effective management. Timely and efficient management of non-fatal suicidal behaviors can prevent future suicidal attempts and completed suicide in most of this highly vulnerable population. Indian studies are very few and without robust study design. Systematic studies in India on this important topic are required. PMID:21206789

This study aimed to examine implementation feasibility and initial treatment outcomes of a behavioral activation (BA) based treatment for adolescent depression, the Adolescent Behavioral Activation Program (A-BAP). A randomized, controlled trial was conducted with 60 clinically referred adolescents with a depressive disorder who were randomized to receive either 14 sessions of A-BAP or uncontrolled evidenced-based practice for depression. The urban sample was 64% female, predominantly Non-Hispanic White (67%), and had an average age of 14.9 years. Measures of depression, global functioning, activation, and avoidance were obtained through clinical interviews and/or through parent and adolescent self-report at preintervention and end of intervention. Intent-to-treat linear mixed effects modeling and logistic regression analysis revealed that both conditions produced statistically significant improvement from pretreatment to end of treatment in depression, global functioning, and activation and avoidance. There were no significant differences across treatment conditions. These findings provide the first step in establishing the efficacy of BA as a treatment for adolescent depression and support the need for ongoing research on BA as a way to enhance the strategies available for treatment of depression in this population.

Synopsis CBT has emerged as a well-established treatment for depression in children and adolescents but treatment trials for adolescents with suicidality are few in number, and their efficacy to date is rather limited. Although a definitive treatment for adolescent suicide attempters has yet to be established, the limited literature suggests that suicidal thoughts and behavior should be directly addressed for optimal treatment outcome. This chapter reviews the rationale underlying the use of CBT for the treatment of depression and suicidality in adolescents, the literature supporting the efficacy of CBT for depressed adolescents, and whether CBT for depression reduces suicidal thoughts and behavior. A description of some of the core cognitive, affective, and behavioral techniques used in CBT treatments of suicidal ideation and behavior in depressed adolescents is included. PMID:21440850

In light of the obesity epidemic, there is growing interest in the use of financial incentives for dietary behavior change. Previous reviews of the literature have focused on randomized, controlled trials and found mixed results. The purpose of this systematic review is to update and expand upon previous reviews by considering a broader range of study designs, including RCTs, quasi-experimental, observational, and simulation studies testing the use of financial incentives to change dietary behavior and to inform both dietetic practice and research. The review was guided by theoretical consideration of the type of incentive used based upon the principles of operant conditioning. There was further examination of whether studies were carried out with an institutional focus and whether incentives took the form of assets or savings. Studies published between 2006 and 2012 were selected for review, and data were extracted regarding study population, intervention design, outcome measures, study duration and follow-up, and key findings. Twelve studies meeting selection criteria were reviewed, with eleven finding a positive association between incentives and dietary behavior change in the short-term. All studies pointed to more specific information on the type, timing, and magnitude of incentives needed to motivate individuals to change behavior, the types of incentives and disincentives most likely to affect the behavior of various socioeconomic groups, and promising approaches for potential policy and practice innovations. Limitations of studies are noted, including the lack of theoretical guidance in the selection of incentive structures and the absence of basic experimental data. Future research should consider these factors even as policymakers and practitioners continue to experiment with this potentially useful approach to addressing obesity. PMID:24836967

This study aims to determine the association between obesity-related behaviors (dietary practices, physical activity and body image) and body weight status among adolescents. A total of 382 adolescents (187 males and 195 females) aged 13 to 15 years in Kajang, Selangor participated in this study. Majority of the respondents were Malays (56.0%), followed by Chinese (30.1%) and Indians (13.9%). Dietary practices, physical activity and body image of the adolescents were assessed through the eating behaviors questionnaire, two-day dietary record, two-day physical activity record and multi-dimensional body image scale (MBIS), respectively. Body weight and height were measured by trained researchers. The prevalence of overweight and obesity (19.5%) was about twice the prevalence of underweight (10.5%). About two-thirds of the respondents (72.3%) skipped at least one meal and half of them (56.2%) snacked between meals with a mean energy intake of 1,641 ± 452 kcal/day. More than half of the respondents (56.8%) were practicing sedentary lifestyle with a mean energy expenditure of 1,631 ± 573 kcal per day. Energy intake (r = 0.153, P < 0.05), physical activity (r = 0.463, P < 0.01) and body image (r = 0.424, P < 0.01) were correlated with BMI. However, meal skipping, snacking and energy expenditure per kg body weight were not associated with body weight status. Multiple linear regression analysis showed that body image, physical activity and energy intake contributed significantly in explaining body weight status of the adolescents. In short, overweight and obesity were likely to be associated not only with energy intake and physical activity, but also body image. Hence, promoting healthy eating, active lifestyle and positive body image should be incorporated in future obesity prevention programmes in adolescents.

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.

Background Obesity has been increasing in adolescents in Fiji and obesogenic dietary patterns need to be assessed to inform health promotion. The objective of this study was to identify the dietary patterns of adolescents in peri-urban Fiji and determine their relationships with standardized body mass index (BMI-z). Methods This study analysed baseline measurements from the Pacific Obesity Prevention In Communities (OPIC) Project. The sample comprised 6,871 adolescents aged 13–18 years from 18 secondary schools on the main island of Viti Levu, Fiji. Adolescents completed a questionnaire that included diet-related variables; height and weight were measured. Descriptive statistics and regression analyses were conducted to examine the associations between dietary patterns and BMI-z, while controlling for confounders and cluster effect by school. Results Of the total sample, 24% of adolescents were overweight or obese, with a higher prevalence among Indigenous Fijians and females. Almost all adolescents reported frequent consumption of sugar sweetened beverages (SSB) (90%) and low intake of fruit and vegetables (74%). Over 25% of participants were frequent consumers of takeaways for dinner, and either high fat/salt snacks, or confectionery after school. Nearly one quarter reported irregular breakfast (24%) and lunch (24%) consumption on school days, while fewer adolescents (13%) ate fried foods after school. IndoFijians were more likely than Indigenous Fijians to regularly consume breakfast, but had a high unhealthy SSB and snack consumption. Regular breakfast (p<0.05), morning snack (p<0.05) and lunch (p<0.05) consumption were significantly associated with lower BMI-z. Consumption of high fat/salt snacks, fried foods and confectionery was lower among participants with higher BMI-z. Conclusions This study provides important information about Fijian adolescents’ dietary patterns and associations with BMI-z. Health promotion should target reducing SSB, increasing

Objectives To examine whether involvement in food preparation tracks over time, between adolescence (15–18 years), emerging adulthood (19–23 years), and the mid-to-late twenties (24–28 years), as well as examine 10-year longitudinal associations between home food preparation, dietary quality and meal patterning. Design Population-based, longitudinal cohort study. Setting Participants were originally sampled from Minnesota public secondary schools (USA). Subjects Participants enrolled in Project EAT (Eating Among Teens)-I, EAT-II, and EAT-III (n=1,321). Results Most participants in their mid-to-late twenties reported an enjoyment of cooking (73% of males, 80% of females); however, few prepared meals including vegetables most days of the week (24% males, 41% females). Participants in their mid-to-late twenties who enjoyed cooking were more likely to have engaged in food preparation as adolescents and emerging adults (p<0.01); those who frequently prepared meals including vegetables were more likely to have engaged in food preparation as emerging adults (p<0.001), but not adolescents. Emerging adult food preparation predicted better dietary quality five years later in the mid-to-late twenties, including higher intakes of fruit, vegetables, dark green/orange vegetables, and less sugar sweetened beverage and fast food consumption. Associations between adolescent food preparation and later dietary quality yielded few significant results. Conclusions Food preparation behaviors appeared to track over time, and engagement in food preparation during emerging adulthood, but not adolescence, was associated with healthier dietary intake during the mid-to-late twenties. Intervention studies are needed to understand whether promoting healthy food preparation results in improvements in eating patterns during the transition to adulthood. PMID:22124458

Recent studies have emphasized the need to consider psychosocial and motivational variables in the study of antisocial behavior in adolescents. Thus, several studies have highlighted the importance of reputation management as a possible explanatory factor. This process of reputation management enables young people to form an image of themselves that they may use in their social interactions. In this study the authors carried out an investigation with data from a sample of 493 adolescents and analyzed (a) the relationships between adolescent reputation management and antisocial behavior and (b) the role of gender in this relationship. The results revealed that a perceived social identity as nonconforming was the best predictor of adolescent antisocial behavior, especially for girls, The data support previous findings on the importance of considering the establishment and management of reputation in the analysis of adolescent antisocial behavior.

Purpose The purpose of this article is to review risk behaviors and their health consequences in adolescents with type 1 diabetes. The existing literature on common risk behaviors in adolescents is examined, with a focus on illicit drug use, alcohol use, smoking, unprotected sexual activity, and disordered eating behaviors. Conclusions A review of the literature highlights the lack of studies of risk behaviors in this population. Much of what is known comes from studies with adolescents in the general population or from studies of adults with type 1 diabetes. Known risk and protective factors for risk behaviors and health outcomes are noted. Based on these findings, suggestions are provided for diabetes educators and health care providers to assess for and prevent risk behaviors in adolescents with type 1 diabetes. Directions for future research in this population are indicated, including the need to develop and test standardized prevention programs. PMID:22002971

Poor dietary habits and obesity are more prevalent in lower socio-economic status (SES) communities. The NEAT Girls cluster randomized controlled trial was a school-based obesity prevention program targeting adolescent girls in low SES schools in NSW, Australia. The aim was to evaluate the 12-month impact of key nutrition program messages on dietary intake and food behaviors. Diet was assessed using a validated semi-quantitative food frequency questionnaire (FFQ). Individual foods were categorized into nutrient-dense or energy-dense, nutrient-poor food groups and the percentage contribution to total energy intake calculated. Participants were aged 13.2±0.5years (n=330). There were no statistically significant group-by-time effects for dietary intake or food related behaviors, with 12-month trends suggesting more intervention group girls had improved water intakes (59% consuming⩽three glasses per day to 54% at 12 months vs. 50% to 61% in controls, p=0.052), with a greater proportion consuming < one sweetened beverage per day (24-41% vs. 34-37% in controls, p=0.057). Further research including more intensive nutrition intervention strategies are required to evaluate whether dietary intake in adolescent girls attending schools in low SES communities can be optimized.
Background The aim of this study was to identify dietary patterns among a representative sample of German adolescents and their associations with energy and nutrient intake, socioeconomic and lifestyle characteristics, and overweight status. Methods In the analysis, data from the German Health Interview and Examination Survey for Children and Adolescents were used. The survey included a comprehensive dietary history interview conducted among 1272 adolescents aged 12 to 17 years. Dietary patterns were determined with principal component analysis (PCA) based on 48 food groups, for boys and girls separately. Results Three dietary patterns among boys and two among girls were identified. Among boys, high adherence to the 'western' pattern was associated with higher age, lower socioeconomic status (SES), and lower physical activity level (PA). High adherence to the 'healthy' pattern among boys, but not among girls, was associated with higher SES, and higher PA. Among boys, high adherence to the 'traditional' pattern was associated with higher age. Among girls, high adherence to the 'traditional and western' pattern was associated with lower age, lower SES and more hours watching TV per day. The nutrient density of several vitamins and minerals, particularly of B-vitamins and calcium, increased with increasing scores of the 'healthy' pattern among both sexes. Conversely, with increasing scores of the 'western' pattern among boys, most nutrient densities decreased, particularly of fibre, beta-carotene, vitamin D, biotin and calcium. Among girls with higher scores of the 'traditional and western' pattern, nutrient densities of vitamin A, C, E, K and folate decreased. Among boys, high adherence to the 'traditional' pattern was correlated with higher densities of vitamin B12 and vitamin D and lower densities of fibre, magnesium and iron. No significant associations between dietary patterns and overweight were found. Conclusions Higher scores for dietary patterns characterized

This paper reviews some of the evidence that dietary behaviors are, in large part, the consequence of automatic responses to contextual food cues, many of which lead to increased caloric consumption and poor dietary choices. We describe studies that illustrate how these automatic mechanisms underlie eating behaviors, as well as evidence that individuals are subject to inherent cognitive limitations, and mostly lack the capacity to consistently recognize, ignore or resist contextual cues that encourage eating. Restaurants and grocery stores are the primary settings from which people obtain food. These settings are often designed to maximize sales of food by strategically placing and promoting items to encourage impulse purchases. Although a great deal of marketing research is proprietary, this paper describes some of the published studies that indicate that changes in superficial characteristics of food products, including packaging and portion sizes, design, salience, health claims, and labeling strongly influence food choices and consumption in ways for which people generally lack insight. We discuss whether contextual influences might be considered environmental risk factors from which individuals may need the kinds of protections that fall under the mission of public health.

The effects of parental attitudes, practices, and television mediation on adolescent sexual behaviors were investigated in a study of adolescent sexuality and media (N=887). Confirmatory factor analyses supported an eight-factor parenting model with television mediation factors as constructs distinct from general parenting practices. Logistic regressions indicated that adolescents reporting greater parental disapproval and limits on viewing at Wave 1 were less likely to initiate oral sex between Waves 1 and 2. Adolescents who reported more sexual communication with parents were more likely to initiate oral sex. Results for vaginal intercourse were similar to those for oral sex. Co-viewing was a significant negative predictor of initiation of sexual behavior. Parental attitudes and television mediation can delay potentially risky adolescent sexual behaviors. PMID:19750131

Risk-behaviors are a major contributor to the leading causes of morbidity among adolescents and young people; however, their association with pathological Internet use (PIU) is relatively unexplored, particularly within the European context. The main objective of this study is to investigate the association between risk-behaviors and PIU in European adolescents. This cross-sectional study was conducted within the framework of the FP7 European Union project: Saving and Empowering Young Lives in Europe (SEYLE). Data on adolescents were collected from randomized schools within study sites across eleven European countries. PIU was measured using Young's Diagnostic Questionnaire (YDQ). Risk-behaviors were assessed using questions procured from the Global School-Based Student Health Survey (GSHS). A total of 11,931 adolescents were included in the analyses: 43.4% male and 56.6% female (M/F: 5179/6752), with a mean age of 14.89 ± 0.87 years. Adolescents reporting poor sleeping habits and risk-taking actions showed the strongest associations with PIU, followed by tobacco use, poor nutrition and physical inactivity. Among adolescents in the PIU group, 89.9% were characterized as having multiple risk-behaviors. The significant association observed between PIU and risk-behaviors, combined with a high rate of co-occurrence, underlines the importance of considering PIU when screening, treating or preventing high-risk behaviors among adolescents.

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.

The relevance of dietary fatty acids (FA) for blood lipids should be assessed in the context of substituting nutrients. Such evidence is lacking for adolescents. This study describes prospective associations of dietary FA with changes in serum lipids during adolescence, and considers the theoretical isocaloric replacements of saturated FA (SFA) with other FA or carbohydrates (CHO). Children from the GINIplus and LISAplus birth cohorts, with data on FA intakes (at age 10 years) and serum lipids (at age 10 and 15 years), were included (n = 1398). Associations of SFA, monounsaturated FA (MUFA), n-3 polyunsaturated FA (n-3 PUFA) and n-6 PUFA, with changes in low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglycerides (TAG), and total cholesterol to HDL ratio (TOTAL:HDL), were assessed by linear regression. Substitution models assessed isocaloric replacements of SFA with MUFA, n-3 PUFA, n-6 PUFA or CHO. Higher SFA intakes were associated with decreasing TAG. No associations were observed for fatty acid intakes with LDL, HDL or TOTAL:HDL. In females, replacing SFA with CHO was associated with increasing LDL, TAG and TOTAL:HDL. Our findings confirm observations in adults, although sex-specific determinants seem relevant in our adolescent population. Overlooking the nutrient context when limiting SFA intakes might have detrimental consequences appreciable as early as adolescence. PMID:28208667

In adolescence, youth antisocial behaviors reach a peak. Parents can use different strategies, such as parental solicitation and control, to monitor their children's activities and try to prevent or reduce their antisocial behaviors. However, it is still unclear if, and for which adolescents, these parental monitoring behaviors are effective. The aim of this study was to examine if the impact of parental solicitation and control on adolescent antisocial behaviors depends on adolescent empathy. In order to comprehensively address this aim, we tested the moderating effects of multiple dimensions (affective and cognitive) of both trait and state empathy. Participants were 379 Dutch adolescents (55.9% males) involved in a longitudinal study with their fathers and mothers. At T1 (conducted when adolescents were 17-year-old) adolescents filled self-report measures of antisocial behaviors and trait empathy during one home visit, while their state empathy was rated during a laboratory session. Furthermore, parents reported their own monitoring behaviors. At T2 (conducted 1 year later, when adolescents were 18-year-old), adolescents reported again on their antisocial behaviors. Moderation analyses indicated that both affective and cognitive state empathy moderated the effects of parental solicitation on adolescent antisocial behaviors. Results highlighted that solicitation had unfavorable effects on antisocial behaviors in adolescents with high empathy whereas the opposite effect was found for adolescents with low empathy. In contrast, neither state nor trait empathy moderated the effects of control on adolescent antisocial behaviors. Theoretical and practical implications of these findings are discussed.

We examined associations between adolescents' and their friends' healthy eating behaviors, specifically breakfast, fruit, vegetable, whole-grain, and dairy food intake as reported by both adolescents and their friends. Data for this study were drawn from EAT-2010 (Eating and Activity among Teens), a population-based study examining multilevel factors of eating, physical activity, and weight-related outcomes among adolescents (80% racial/ethnic minority) in Minneapolis/St Paul, MN, during the 2009-2010 academic year. In-class surveys were completed by 2,043 adolescents in 20 schools. Adolescents identified friends from a class roster; friends' survey data were then linked to each participant. Generalized estimating equation linear regression models were used to examine associations between adolescents' healthy eating behaviors and these behaviors from their friends (friend group and best friends), adjusting for sociodemographic characteristics. Significant positive associations were found for breakfast eating between adolescents and their friend groups and best friends (friend groups β=.26, P<0.001; best friends β=.19, P=0.004), as well was for whole-grain intake (friend groups β=.14, P<0.001; best friends β=.13, P=0.003) and dairy food intake (friend groups β=.08, P=0.014; best friends β=.09, P=0.002). Adolescents' and their best friends' vegetable intake were also significantly related (β=.09, P=0.038). No associations were seen among friends for fruit intake. Findings from our study suggest that adolescent friends exhibit similarities in healthy eating patterns. Registered dietitians and health professionals may consider developing strategies to engage friends to promote adolescents' healthy dietary behaviors.

The current study examines the contextual effects of community structural characteristics, as well as the mediating role of key social mechanisms, on youth suicidal behavior in Iceland. We argue that the contextual influence of community structural instability on youth suicidal behavior should be mediated by weak attachment to social norms and values (anomie), and contact with suicidal others (suggestion-imitation). The data comes from a national survey of 14-16 years old adolescents. Valid questionnaires were obtained from 7018 students (response rate about 87%). The findings show that the community level of residential mobility has a positive, contextual effect on adolescent suicidal behavior. The findings also indicate that the contextual effect of residential mobility is mediated by both anomie and suggestion-imitation. The findings offer the possibility to identify communities that carry a substantial risk for adolescent suicide as well as the mechanisms that mediate the influence of community structural characteristics on adolescent risk behavior.

Marital breakup has been associated with numerous behavioral problems in children, such as sexual risk behaviors. This research is the first to examine sexual behaviors of Spanish adolescents related to whether their parents were married or divorced. Participants were 342 boys and girls aged between 14 and 18 years. The sample provided confidential information about their sexual behavior and birth control methods. Significant differences were only found in percentages of adolescents who had engaged in mutual masturbation, intercourse, or oral sex, and who had practiced these sexual relations in the last six months, in both cases, they were higher when the parents had broken their marital relationship. Regarding adolescents of divorced parents, engaging in intercourse is more likely in older teenagers who live with a stepparent. Moreover, older adolescents who were younger when parents divorced and who live in a reconstituted family, have more sexual partners. These and other findings are discussed.

OBJECTIVE To analyze the relationships between sexual behavior and risk factors to physical and mental health in adolescents. METHODS Study of 3,195 pupils aged 15 to 19 in secondary education, in public and private schools in 10 state capitals in Brazil between 2007 and 2008. Multi-stage (schools and pupils) cluster sampling was used in each city and public and private educational network. All of the students selected completed a questionnaire on the following items: socioeconomic and demographic data; sexual behavior; having sex with those of the same sex, the opposite sex, or both; alcohol and cannabis use; using condoms; traumatic sexual experiences as a child or adolescent; suicidal thoughts. The analysis included describing frequencies, Chi-square test, analysis of multiple and cluster correspondence. Responses to an open ended question in which the adolescent expressed general comments about themselves and their lives were qualitatively analyzed using content analysis. RESULTS Around 3.0% of adolescents reported homosexual or bisexual behavior, with no difference according to sex, age, skin color, social status family structure or educational network. Adolescents with homosexual/bisexual sexual behavior, compared to their heterosexual peers, reported: (p < 0.05): getting drunk (18.7% and 10.5%, respectively), frequent cannabis use (6.1% and 2.1%, respectively), suicidal thoughts (42.5% and 18.7%, respectively), and having been the victim of sexual violence (11.7% and 1.5%; respectively). Adolescents with homosexual/bisexual sexual behavior reported that they used condoms less frequently (74.2%) than their heterosexual peers (48.6%, p < 0.001). In the correspondence analysis, three groups were found, one composed of adolescents with homosexual/bisexual behavior and experiencing risk factors; suffering sexual violence, never using a condom, suicidal thoughts, frequent cannabis use; another composed of occasional cannabis and condom users, who got drunk

Background Hypertension is the leading cause for heart disease and stroke, for mortality and morbidity worldwide, and a high sodium-to-potassium intake ratio is considered a stronger risk factor for hypertension than sodium alone. Objective This study aims to evaluate sodium and potassium urinary excretion, and assess the food sources of these nutrients in a sample of Portuguese adolescents. Design A cross-sectional study with a sample of 250 Portuguese adolescents. Sodium and potassium excretion were measured by one 24-h urinary collection, and the coefficient of creatinine was used to validate completeness of urine collections. Dietary sources of sodium and potassium were assessed using a 24-h dietary recall. Results Valid urine collections were provided by 200 adolescents (118 girls) with a median age of 14.0 in both sexes (p=0.295). Regarding sodium, the mean urinary excretion was 3,725 mg/day in boys and 3,062 mg/day in girls (p<0.01), and 9.8% of boys and 22% of girls met the World Health Organization (WHO) recommendations for sodium intake. Concerning potassium, the mean urinary excretion was 2,237 mg/day in boys and 1,904 mg/day in girls (p<0.01), and 6.1% of boys and 1.7% of girls met the WHO recommendations for potassium intake. Major dietary sources for sodium intake were cereal and cereal products (41%), meat products (16%), and milk and milk products (11%); and for potassium intake, main sources were milk and milk products (21%), meat products (17%), and vegetables (15%). Conclusions Adolescents had a high-sodium and low-potassium diet, well above the WHO recommendations. Health promotion interventions are needed in order to decrease sodium and increase potassium intake. PMID:27072344

Objective This study possessed two aims: (1) to develop and validate aclinician -friendly measure of academic problem behavior that is relevant to the assessment of adolescents with ADHD and (2) to better understand the cross-situational expression of academic problem behaviors displayed by these youth. Method Within a sample of 324 adolescents with DSM-IV-TR diagnosed ADHD (age M=13.07, SD=1.47), parent, teacher, and adolescent self-report versions of the Adolescent Academic Problems Checklist (AAPC) were administered and compared. Item prevalence rates, factorial validity, inter-rater agreement, internal consistency, and concurrent validity were evaluated. Results Findings indicated the value of the parent and teacher AAPC as a psychometrically valid measure of academic problems in adolescents with ADHD. Parents and teachers offered unique perspectives on the academic functioning of adolescents with ADHD, indicating the complementary roles of these informants in the assessment process. According to parent and teacher reports, adolescents with ADHD displayed problematic academic behaviors in multiple daily tasks, with time management and planning deficits appearing most pervasive. Conclusions Adolescents with ADHD display heterogeneous academic problems that warrant detailed assessment prior to treatment. As a result, the AAPC may be a useful tool for clinicians and school staff conducting targeted assessments with these youth. PMID:24933215

Peer relations are central to adolescent life and, therefore, are crucial to understanding adolescents' engagement in various behaviors. In recent years, public health research has increasingly devoted attention to the implications of peer relations for the kinds of adolescent behaviors that have a direct impact on health. This article advocates for a continuation of this trend. With this aim, we highlight key themes in the rich literature on the general developmental significance of adolescent-peer relations, provide an overview of how these themes have been incorporated into public health research and practice, and suggest future avenues for peer-focused public health research that can inform adolescent health promotion in the United States.

Adolescence is a developmental period when physical and cognitive abilities are optimized, when social skills are consolidated, and when sexuality, adolescent behaviors, and frontal cortical functions mature to adult levels. Adolescents also have unique responses to alcohol compared with adults, being less sensitive to ethanol sedative–motor responses that most likely contribute to binge drinking and blackouts. Population studies find that an early age of drinking onset correlates with increased lifetime risks for the development of alcohol dependence, violence, and injuries. Brain synapses, myelination, and neural circuits mature in adolescence to adult levels in parallel with increased reflection on the consequence of actions and reduced impulsivity and thrill seeking. Alcohol binge drinking could alter human development, but variations in genetics, peer groups, family structure, early life experiences, and the emergence of psychopathology in humans confound studies. As adolescence is common to mammalian species, preclinical models of binge drinking provide insight into the direct impact of alcohol on adolescent development. This review relates human findings to basic science studies, particularly the preclinical studies of the Neurobiology of Adolescent Drinking in Adulthood (NADIA) Consortium. These studies focus on persistent adult changes in neurobiology and behavior following adolescent intermittent ethanol (AIE), a model of underage drinking. NADIA studies and others find that AIE results in the following: increases in adult alcohol drinking, disinhibition, and social anxiety; altered adult synapses, cognition, and sleep; reduced adult neurogenesis, cholinergic, and serotonergic neurons; and increased neuroimmune gene expression and epigenetic modifiers of gene expression. Many of these effects are specific to adolescents and not found in parallel adult studies. AIE can cause a persistence of adolescent-like synaptic physiology, behavior, and sensitivity

The current study tested whether greater monitoring by mothers and greater disclosure by early adolescents was linked to greater agreement in mothers' and adolescents' reports of rule-breaking behavior. In doing so, the article demonstrated how polynomial regression analyses can be used to test hypotheses in which informant discrepancies serve as the dependent variable. Data were obtained from 218 mother-adolescent dyads (M adolescent age = 11.5 years, 51% female, 49% European American, 47% African American). Mothers and early adolescents provided reports of their perceptions of maternal monitoring (i.e., solicitation and control through rules), adolescent disclosure, and adolescent rule-breaking behavior. Polynomial regression models tested monitoring and disclosure as moderators of the association between mothers' and adolescents' reports of the adolescents' rule-breaking behavior. Mothers' reports of rule-breaking behavior were more strongly associated with adolescents' reports of their own rule-breaking behavior when mothers reported engaging in more solicitation or control through rules. There was less agreement in mothers' and adolescents' reports of rule breaking when adolescents reported that their mothers engaged in more solicitation. Adolescent disclosure did not moderate agreement in reported rule-breaking behavior. Greater monitoring by mothers may reduce the discrepancy in mother-adolescent reports of rule-breaking behavior. Findings also demonstrate the greater validity of polynomial regression approaches over difference scores when testing hypotheses with informant agreement as the outcome.

The primary purpose of this study was to examine the relationship between adolescents' sleep-wake patterns and risk-taking behavior. A second goal was to replicate the results obtained by Wolfson and Carskadon (1998) regarding adolescents' sleep habits. Three hundred eighty-eight adolescents (217 males, 171 females) completed the Sleep Habits Survey and the Youth Risk Behavior Survey. The results indicated that adolescents who reported longer weekend delay and higher levels of sleep problems also reported significantly higher levels of risk-taking behaviors, and students' weekend delay was also related to their academic performance in this sample. As in the sample studied by Wolfson and Carskadon (1998), the adolescents in this study exhibited changes in both weekday and weekend sleep habits across grade/age. However in the present study, only school-night total sleep time and weekend delay were related to adolescents' daytime functioning, with no significant relationships being found between weekend oversleep and daytime functioning. This provides partial support for the findings of Wolfson and Carskadon (1998). Overall, sleep-wake patterns were found to relate to risk-taking behavior during adolescence in this study.

The main purpose of this study was to explore some of the social, dietary and lifestyle factors that could be related to the risk of obesity among adolescents in Bahrain. A multistage stratified method was used to select secondary school students (15-18years old) from governmental schools in Bahrain. The total sample selected was 735 (339 males and 396 females). A pre-validated self-report questionnaire was used to obtain information on socio-demographics, food and the lifestyle habits of adolescents. Weight and height were taken and percentiles of Body Mass Index for age and gender were used to classify the adolescents as non-obese and obese (overweight and obese), using NHANES-1 growth standard. In general, the prevalence of overweight and obesity was 29.5% and 36.8% among males and females, respectively. The risk of obesity was not consistent among male and female adolescents. Mothers' education was found to be a risk factor for obesity among both males and females (p=0.0167 and p=0.007, respectively). Bringing food from home to school (odds ratio (OR)=0.54, confidence interval (CI) 0.35-0.81) was protective factor for obesity among females but not among males. Fathers' education (p=0.0167), rank among siblings (p=0.009), place where breakfast is eaten (p=0.0398), eating between lunch and dinner (p=0.0152), fruit intake (p=0.042), sweet intake (p=0.0192), size of burger (p=0.002) and hours of watching television per day (p=0.004) were significantly associated with the risk of obesity among males, but not among females. Various social, dietary and lifestyle factors were found to contribute to obesity among adolescents in Bahrain. These factors should be considered in school health policy in the country.

Suicide is the leading cause of premature death in individuals with psychotic disorders. Risk for onset of suicidal behaviors tends to begin in adolescence, remaining high into young adulthood. The present study aims to evaluate the interplay of early onset psychosis and suicide risk by examining suicidal behaviors (ideation, planning, and attempts) in children and adolescents with psychotic disorders (PD) compared to typically developing peers (TD). Twenty five youths were recruited and were diagnostically evaluated for psychosis. We found that the PD children exhibited significantly higher levels of suicidal behaviors than TD children, even when parsed into individual at-risk behaviors.

This study was undertaken to understand dietary behavior as situated within the household, an important social context that serves to either inhibit or promote a healthy diet. Data were collected as part of a worksite-based health behavior intervention trial that took place between 1999 and 2003 in small manufacturing businesses in New England, USA. The subjects were a cohort of 790 male and female workers who participated in the intervention trial and responded to both the baseline and the 18-month follow-up surveys. Regression models were built to determine whether proportion of household responsibility predicted daily fruit and vegetable consumption and weekly red meat consumption at 18-months. The results indicate that participants who were responsible for earning most or all of the money to support the household ate more servings of fruits and vegetables per day at 18-month follow-up than those without this responsibility. Further, those responsible for earning about half ate fewer servings of red meat than those responsible for earning most or all of the money to support the household. The results for red meat consumption differed by sex, such that responsibility for more than half or less than half of the money to support the household had different effects for men and women. The results of this study demonstrate that the distribution of household responsibilities can be an important factor in determining the effectiveness of a worksite-based health behavior intervention and that these effects can be different for women versus men.

Background Today, ensuring people’s health and well-being has become a concern for societies. Health status results from an interaction of an individuals’ various psychological, social, and physical aspects. Objectives This study aims to investigate the relationship of parental mental health and dietary pattern with adolescent mental health. Patients and Methods In this study, 250 high school students in Shiraz were selected using random cluster sampling. The samples were analyzed using the Food Frequency Questionnaire (FFQ) and the General Health Questionnaire (GHQ-28). Results According to the findings, parental mental health explains 22% of the variance in children’s mental health, so that in simultaneous regression, physical dimensions, anxiety, social functioning, and depression predicted 13%, 24%, 11%, and 24% of the variance of criterion variables, respectively. No significant relationship was observed between dietary pattern and adolescent mental health dimensions. There was a significant negative relationship only between depression and vegetable intake. Moreover, fruit (r = 0.15, P < 0.05) and vegetable (r = 0.16, P < 0.05) intake had a significant relationship with parental mental health dimensions. Conclusions Parents’ mental health and their psychological characteristics can be related to children’s mental health and affect their dietary intake patterns. PMID:27218068

This report describes the development and psychometric testing of the Systems Thinking Scale for Adolescent Behavior Change (STS-AB). Following item development, initial assessments of understandability and stability of the STS-AB were conducted in a sample of nine adolescents enrolled in a weight management program. Exploratory factor analysis of the 16-item STS-AB and internal consistency assessments were then done with 359 adolescents enrolled in a weight management program. Test-retest reliability of the STS-AB was .71, p = .03; internal consistency reliability was .87. Factor analysis of the 16-item STS-AB indicated a one-factor solution with good factor loadings, ranging from .40 to .67. Evidence of construct validity was supported by significant correlations with established measures of variables associated with health behavior change. We provide beginning evidence of the reliability and validity of the STS-AB to measure systems thinking for health behavior change in young adolescents.

This study examined the correlates of dietary energy under-reporting (UR) and over-reporting (OV) in European adolescents. Two self-administered computerised 24-h dietary recalls and physical activity data using accelerometry were collected from 1512 adolescents aged 12·5-17·5 years from eight European countries. Objective measurements of height and weight were obtained. BMI was categorised according to Cole/International Obesity Task Force (IOTF) cut-off points. Diet-related attitudes were assessed via self-administered questionnaires. Reported energy intake (EI) was compared with predicted total energy expenditure to identify UR and OV using individual physical activity objective measures. Associations between misreporting and covariates were examined by multilevel logistic regression analyses. Among all, 33·3 % of the adolescents were UR and 15·6 % were OV when considering mean EI. Overweight (OR 3·25; 95 % CI 2·01, 5·27) and obese (OR 4·31; 95 % CI 1·92, 9·65) adolescents had higher odds for UR, whereas underweight individuals were more likely to over-report (OR 1·67; 95 % CI 1·01, 2·76). Being content with their own figures (OR 0·61; 95 % CI 0·41, 0·89) decreased the odds for UR, whereas frequently skipping breakfast (OR 2·14; 95 % CI 1·53, 2·99) was linked with higher odds for UR. Those being worried about gaining weight (OR 0·55; 95 % CI 0·33, 0·92) were less likely to OV. Weight status and psychosocial weight-related factors were found to be the major correlates of misreporting. Misreporting may reflect socially desirable answers and low ability to report own dietary intakes, but also may reflect real under-eating in an attempt to lose weight or real over-eating to reflect higher intakes due to growth spurts. Factors influencing misreporting should be identified in youths to clarify or better understand diet-disease associations.

As binge eating is a common behavior throughout the general population, we hypothesized that body dissatisfaction would produce binge eating via its prediction of dieting. Six hundred eight individuals were nonrandomly recruited from the community. The mean age and body mass index of participants were 34.76 years (SD, 14.41) and 27.82 kg/m(2) (SD, 9.54), respectively. Participants were asked to complete several self-report questionnaires, which included measures of dieting status, binge eating behavior, body dissatisfaction, overvaluation of weight and shape, and self-esteem. The results showed that dieting was a common behavior; 38.1% of participants reported dieting during the past year. Binge eating during the previous 6 months was reported by 9.9% of the sample and was associated with a higher body mass index as well as more frequent dieting. A model including dieting status, overvaluation of weight and shape, shape satisfaction, and self-esteem showed the best fit for the prediction of binge eating behavior. Moreover, those who dieted and overvalued their weight and shape were 2.01 and 2.31 times more likely, respectively, to binge eat. Structural equation modeling revealed that body dissatisfaction caused dietary restraint, thus triggering binge eating. Both dieting and overvaluation of weight and shape are important risk factors for the development of binge eating disorders. Dieting and binge eating are common behaviors that represent a risk for the development of both excess weight and eating disorders. The structural model proposed in this study could be beneficial in understanding this causal relationship.

By adolescence, appraisal of one's past life experience becomes critical to the stage-salient issue of identity formation. This study examined adolescents' perceptions of their maltreatment experiences. It scrutinized the combined and unique contribution of five maltreatment types (i.e., physical abuse, sexual abuse, psychological abuse, neglect, and exposure to family violence) to variance in adolescent adjustment. It was predicted that these maltreatment types would account for significant variance in adjustment when controlling for the context variables of age, sex, socioeconomic status, IQ, and stressful life events. Adolescents (N = 160, aged 11-17) were randomly selected from the open caseload of a child protection agency. Participants completed global severity ratings regarding their experiences of the five types of maltreatment, as well as a battery of measures assessing self- and caretaker-reported externalizing and internalizing symptomatology. The youths' maltreatment ratings significantly predicted self-reported adjustment, even when controlling for all context variables. Psychological maltreatment was the most predictively potent maltreatment type, and enhanced the predictive utility of other maltreatment types. Significant sex differences in the sequelae of perceived maltreatment were evident. Also, interactions between youths' ratings and those obtained from CPS files were detected. The findings were consistent with recent research in child maltreatment, and contribute to our understanding of developmental psychopathology among adolescents.

Screen time, but not overall sedentary behaviour, is consistently related to cardiometabolic health in adolescents. Because of the associations screen time has with dietary intake, diet may be an important factor in the screen time and health relationship; however, evidence has not previously been synthesized. Thus, the aim of this systematic review was to explore whether the associations between various sedentary behaviours and cardiometabolic risk markers are independent of dietary intake in adolescents. Online databases and personal libraries were searched for peer-reviewed original research articles published in English before March 2014. Included studies assessed associations between sedentary behaviour and cardiometabolic markers in 12- to 18-year-olds and adjusted for dietary intake. Twenty-five studies met the inclusion criteria. From the 21 studies examining sedentary behaviour and adiposity, the majority found significant positive associations between television viewing, screen time and self-reported overall sedentary behaviour with markers of adiposity, independent of dietary intake. No significant associations between screen time with blood pressure and cholesterol were reported. Sedentary behaviour appears to be associated with adiposity in adolescents, irrespective of dietary intake. However, the variability of dietary variables between studies suggests further work is needed to understand the role of dietary intake when examining these associations in youth. PMID:26098509

Despite the importance of understanding sympathy and prosocial behaviors, research on the development of these tendencies in adolescence remains relatively sparse. In the present study, we examined age trends and bidirectional longitudinal relations in sympathy and prosocial behaviors across early to middle adolescents. Participants were 500 12-year-olds at Time 1 (52% girls, 70% European American) who completed measures of sympathy and prosocial behaviors at 5 different time points, each approximately 1 year apart. Results showed significant bidirectional relations between sympathy and prosocial behaviors across all time points, and an initial decrease of prosocial behaviors followed by an increase into middle adolescence. The implications for prosocial developmental theories and research are discussed. (PsycINFO Database Record

Tobacco use and its concomitant, nicotine dependence, are increasing in African countries and other parts of the developing world. However, little research has assessed nicotine dependence in South Africa or other parts of the African continent. Previous research has found that adolescent problem behaviors, including tobacco use, tend to cluster. This study examined the relationship between nicotine dependence and adolescent problem behaviors in an ethnically diverse sample of urban South African adolescents. A community sample (N = 731) consisting of "Black," "White," "Coloured," and "Indian" youths aged 12-17 years was drawn from the Johannesburg metropolitan area. Structured interviews were administered by trained interviewers. Nicotine dependence was assessed by the Fagerström Test of Nicotine Dependence. Logistic regression analyses showed that higher levels of nicotine dependence significantly predicted elevated levels of violent behavior, deviant behavior, marijuana and other illegal drug use, binge drinking, early sexual intercourse, multiple sexual partners, and inconsistent condom use, despite control on the adolescents' demographic characteristics, peer smoking, conflict with parents, peer deviance, and the availability of legal and illegal substances. These relationships were robust across ethnicity and gender. The findings indicate the need for policy makers and prevention and intervention programs in South Africa to consider adolescent nicotine dependence in conjunction with comorbid problem behaviors, including other substance use, sexual risk behaviors, and deviant behaviors.

Neurodevelopmental theories of risk behavior hypothesize that low behavioral control in combination with high reward sensitivity explains adolescents' risk behavior. However, empirical studies examining this hypothesis while including actual risk taking behavior in adolescence are lacking. In this study we tested whether the imbalance between behavioral control and reward sensitivity underlies risk taking behavior in adolescence, using a nationally representative longitudinal sample of 715 adolescents, of which 66% revealed an increased risk for mental health problems. To assess behavioral control at age 11 we used both self-report (effortful control) as well as behavioral measures of cognitive control (i.e., working memory and response inhibition). Reward sensitivity was assessed with the Bangor Gambling Task. The main finding of this study was that effortful control at age 11 was the best predictor of risk taking behavior (alcohol and cannabis use) at age 16, particularly among adolescents who were more reward sensitive. Risk taking behavior in adolescents might be explained by relatively weak behavioral control functioning combined with high sensitivity for reward.

Food neophobia (FN) is described as the rejection to eat unknown foods. Because only little is known about the role of FN in adolescence the aim of this study was to examine potential determinants of FN and associations with dietary habits of DONALD study participants. FN was measured with Pliner's and Hobden's Food Neophobia Scale (FN Score (FNS): range 10-70) in 166 10-18-year-old adolescents. Participants' age, sex, body weight status and duration of breast-feeding as well as parents' FN and educational status were considered as determinants. Energy intake, distribution of macronutrients and two variety scores were calculated from 3-day weighed dietary records. Multivariable general linear models were performed for data analyses. Boys and girls did not differ in their FNS (median (Min-Max): boys 31 (10-58), girls 32 (14-59)). Increasing age (p = 0.010) and duration of total breast-feeding (p = 0.006) were associated with decreasing FNS in girls only. FN was further positively associated with parental FN in the total sample (p = 0.004). FN was negatively associated with protein intake in the total sample (p = 0.017). The overall low level of FN in the DONALD study can be ascribed to the low level of FN in adolescence in general. Congruently with other studies, age and breast-feeding duration were identified as determinants of girls' FN and parental FN was identified as determinant of FN in the total sample. Further, our results indicate that FN leads to reduced protein intakes. Dietary variety was not strongly affected, possibly because of a broad variety of food supply in Germany.

Background Risk-taking behavior is a major cause of morbidity and mortality in adolescence. In the context of decision theory and motivated (goal-directed) behavior, risk-taking reflects a pattern of decision-making that favors the selection of courses of action with uncertain and possibly harmful consequences. We present a triadic, neuroscience systems-based model of adolescent decision-making. Method We review the functional role and neurodevelopmental findings of three key structures in the control of motivated behavior, i.e. amygdala, nucleus accumbens, and medial/ventral prefrontal cortex. We adopt a cognitive neuroscience approach to motivated behavior that uses a temporal fragmentation of a generic motivated action. Predictions about the relative contributions of the triadic nodes to the three stages of a motivated action during adolescence are proposed. Results The propensity during adolescence for reward/novelty seeking in the face of uncertainty or potential harm might be explained by a strong reward system (nucleus accumbens), a weak harm-avoidant system (amygdala), and/or an inefficient supervisory system (medial/ventral prefrontal cortex). Perturbations in these systems may contribute to the expression of psychopathology, illustrated here with depression and anxiety. Conclusions A triadic model, integrated in a temporally organized map of motivated behavior, can provide a helpful framework that suggests specific hypotheses of neural bases of typical and atypical adolescent behavior.

Objectives To study the dietary behavior and knowledge about dental erosion and self-reported symptoms that can be related to dental erosion among Chinese adults in Hong Kong. Methods Chinese adults aged 25-45 years were randomly selected from a list of registered telephone numbers generated by computer. A telephone survey was administered to obtain information on demographic characteristics, dietary habits, dental visits, and knowledge of and presence of self-reported symptoms that can be related to dental erosion. Results A total of 520 participants were interviewed (response rate, 75%; sampling error, ± 4.4%) and their mean age was 37. Most respondents (79%) had ever had caries, and about two thirds (64%) attended dental check-ups at least once a year. Respondents had a mean of 5.4 meals per day and 36% had at least 6 meals per day. Fruit (89%) and lemon tea/water (41%) were the most commonly consumed acidic food and beverage. When asked if they ever noticed changes in their teeth, most respondents (92%) said they had experienced change that can be related to erosion. However, many (71%) had never heard about dental erosion and 53% mixed up dental erosion with dental caries. Conclusion Hong Kong Chinese adults have frequent intake of food and many have experienced symptoms that can be related to dental erosion. Their level of awareness of and knowledge about dental erosion is generally low, despite most of them have regular dental check-ups. Dental health education is essential to help the public understand dental erosion and its damaging effects. PMID:20525244

The last decade of research has suggested that family meals play an important role in promoting healthful dietary intake in youth. However, little is known about the structural characteristics and interpersonal dynamics of family meals that might help to inform why family meals are protective for youth. The current mixed methods, cross-sectional study conducted in 2010-2011 includes adolescents and parents who participated in two linked population-based studies. Participants included 40 parents (91.5% female) and adolescents (57.5% female) from the Minneapolis/St Paul, MN, area participating in EAT (Eating and Activity Among Teens) 2010 and F-EAT (Families and Eating and Activity Among Teens). The structural (eg, length of the meal, types of foods served) and interpersonal characteristics (eg, communication, emotion/affect management) of family meals were described, and associations between interpersonal dynamics at family meals and adolescent body mass index and dietary intake were examined via direct observational methods. Families were videorecorded during two mealtimes in their homes. Results indicated that family meals were approximately 20 minutes in length, included multiple family members, were typically served family style (70%), and occurred in the kitchen 62% of the time and 38% of the time in another room (eg, family room, office). In addition, significant associations were found between positive interpersonal dynamics (ie, communication, affect management, interpersonal involvement, overall family functioning) at family meals and lower adolescent body mass index and higher vegetable intake. These findings add to the growing body of literature on family meals by providing a better understanding of what is happening at family meals in order to inform obesity-prevention studies and recommendations for providers working with families of youth.

Research has demonstrated a relation between alcohol use and engaging in high-risk sexual behaviors. Alcohol use, especially binge drinking, has been linked to a host of problems including high-risk sexual behavior, date rape, and academic problems. As such, the purpose of this study was to provide a descriptive profile of alcohol consumption among adolescents and to examine the relations of alcohol use (lifetime, current, binge) with sexual activity variables (sexual initiation, multiple sex partners, condom use, and pregnancy) among adolescents completing the 1993-1999 Youth Risk Behavior Survey. Analysis showed alcohol use was associated with high-risk sexual activity. Binge drinking had stronger relations with sexual activity variables than lifetime use and current use of alcohol. This result is of particular concern, in that binge drinking has been implicated in many problem behaviors. As such, it is of great importance to intervene in the high-risk practices of adolescents before problems occur.

This study estimated the levels and differentials in nutritional status and dietary intake and relevant knowledge of adolescent girls in rural Bangladesh using data from the Baseline Survey 2004 of the National Nutrition Programme. A stratified two-stage random cluster-sampling was used for selecting 4,993 unmarried adolescent girls aged 13-18 years in 708 rural clusters. Female interviewers visited girls at home to record their education, occupation, dietary knowledge, seven-day food-frequency, intake of iron and folic acid, morbidity, weight, and height. They inquired mothers about age of their daughters and possessions of durable assets to divide households into asset quintiles. Results revealed that 26% of the girls were thin, with body mass index (BMI)-for-age <15th percentile), 0.3% obese (BMI-for-age >95th percentile), and 32% stunted (height-for-age < or = 2SD). Risks of being thin and stunted were higher if girls had general morbidity in the last fortnight and foul-smelling vaginal discharge than their peers. Consumptions of non-staple good-quality food items in the last week were less frequent and correlated well positively with the household asset quintile. Girls of the highest asset quintile ate fish/meat 2.1 (55%) days more and egg/milk two (91%) days more than the girls in the lowest asset quintile. The overall dietary knowledge was low. More than half could not name the main food sources of energy and protein, and 36% were not aware of the importance of taking extra nutrients during adolescence for growth spurt. The use of iron supplement was 21% in nutrition-intervention areas compared to 8% in non-intervention areas. Factors associated with the increased use of iron supplements were related to awareness of the girls about extra nutrients and their access to mass media and education. Community-based adolescent-friendly health and nutrition education and services and economic development may improve the overall health and nutritional knowledge and

Adolescents, organizing their behavior in the space of school should take into account the system of rules existing in the institution. The development of normative behavior allows the teenager to understand their inner world and people around them. Failure to understand the regulatory requirements reduces the possibilities of social adaptation of…

OBJECTIVE To analyze the prevalence of sedentary behavior and associated factors in adolescents. METHODS A cross-sectional study with adolescents aged 10 to 17 years, of both sexes, belonging to a 1994-1999 birth cohort in the city of Cuiabá, MT, Central Western Brazil. Data were collected using a questionnaire containing sociodemographic, economic, lifestyle and anthropometric variables. Sedentary behavior was determined as using television and/or computer/video games for a time greater than or equal to 4 hours/day. Associations with sedentary behavior were evaluated using body mass index in childhood and adolescence and sociodemographic and behavioral variables using hierarchical logistic regression. RESULTS The overall prevalence of sedentary behavior was 58.1%. Of the 1,716 adolescents evaluated, 50.7% (n = 870) were male. In multivariate analysis, after adjustment for confounding factors, the variables that remained associated with sedentary behavior were: age (14 and over) (OR = 3.51, 95%CI 2.19;5.60); higher socioeconomic class (OR = 3.83, 95%CI 2.10;7.01), higher level of maternal education (OR = 1.81, 95%CI 1.09;3.01); living in the country (OR = 0.49, 95%CI 0.30;0.81); insufficient physical activity (OR = 1.25, 95%CI 1.02;1.53); experimentation with alcoholic beverages (OR = 1.34, 95%CI 1.08;1.66) and being overweight in adolescence (OR = 1.33, 95%CI 1.06;1.68). CONCLUSIONS The high proportion of adolescents in sedentary activities and the lack of association with being overweight in childhood, indicates the need for educational initiatives to reduce multiple risk behaviors. Encouraging physical activity in young people as a way of reducing sedentary behavior and, consequently, being overweight is fundamental. PMID:24897048
Adolescence and puberty are highly important periods for postnatal brain maturation. During adolescence, drastic changes of neuronal architecture and function occur that concomitantly lead to distinct behavioral alterations. Unsurprisingly in view of the multitude of ongoing neurodevelopmental processes in the adolescent brain, most adult neuropsychiatric disorders have their roots exactly during this time span. Adolescence and puberty are therefore crucial developmental periods in terms of understanding the causes and mechanisms of adult mental illness. Valid animal models for adolescent behavior and neurodevelopment might offer better insights into the underlying mechanisms and help to identify specific time windows with heightened susceptibility during development. In order to increase the translational value of such models, we urgently need to define the detailed timing of adolescence and puberty in laboratory rodents. The aim of the present review is to provide a more precise delineation of the time course of these developmental periods during postnatal life in rats and mice and to discuss the impact of adolescence and related neurodevelopmental processes on the heightened susceptibility for mental disorders.

This study was undertaken to understand dietary behavior as situated within the household, an important social context that serves to either inhibit or promote a healthy diet. Data were collected as part of a worksite-based health behavior intervention trial that took place between 1999 and 2003 in small manufacturing businesses in New England, U.S.A. The subjects were a cohort of 790 male and female workers who participated in the intervention trial and responded to both the baseline and the 18-month follow-up surveys. Regression models were built to determine whether proportion of household responsibility predicted daily fruit and vegetable consumption and weekly red meat consumption at 18-months. The results indicate that participants who were responsible for earning most or all of the money to support the household ate more servings of fruits and vegetables per day at 18-month follow-up than those without this responsibility. Further, those responsible for earning about half ate fewer servings of red meat than those responsible for earning most or all of the money to support the household. The results for red meat consumption differed by sex, such that responsibility for more than half or less than half of the money to support the household had different effects for men and women. The results of this study demonstrate that the distribution of household responsibilities can be an important factor in determining the effectiveness of a worksite-based health behavior intervention and that these effects can be different for women versus men.

Although peers are a major influence during adolescence, the relative importance of specific mechanisms of peer influence on the development of problem behavior is not well understood. This study investigated five domains of peer influence and their relationships to adolescents' problem and prosocial behaviors. Self-report and teacher ratings were obtained for 1787 (53 % female) urban middle school students. Peer pressure for fighting and friends' delinquent behavior were uniquely associated with aggression, drug use and delinquent behavior. Friends' prosocial behavior was uniquely associated with prosocial behavior. Friends' support for fighting and friends' support for nonviolence were not as clearly related to behavior. Findings were generally consistent across gender. This study highlights the importance of studying multiple aspects of peer influences on adolescents' behavior.

Interest in empirically derived dietary patterns has increased over the past decade. However, relatively few studies have evaluated dietary patterns using different dietary methods, or in young populations. We quantitatively compared dietary patterns from a food frequency questionnaire (FFQ) with those from a 3-day food record (FR) in a cohort of adolescents. Subjects from the Western Australian Pregnancy Cohort (Raine) Study completed a semi-quantitative FFQ and a 3-day FR at 14 y of age (n=783). Major dietary patterns were identified using exploratory factor analysis on 38 food groups. Dietary pattern z-scores were compared using 95% limits of agreement (LOA) and Spearman’s r. Two major dietary patterns were identified in the FFQ and FR. A ‘Healthy’ pattern was high in fresh fruit, vegetables, whole grains and grilled or canned fish. A ‘Western’ pattern was high in takeaway foods, confectionery, soft drinks, crisps and fried potato. The nutrient profiles of these dietary patterns were similar when estimated by the FFQ and FR. The LOA between dietary pattern scores from the FFQ and FR were -1.69 to 1.75 (‘Healthy’) and -1.89 to 1.82 (‘Western’). Minor differences in agreement were observed when boys and girls were analysed separately. Spearman’s correlation coefficients between the FFQ and FR were r=0.45 (‘Healthy’) and r=0.36 (‘Western’). Comparable dietary patterns may be obtained from a FFQ and FR using exploratory factor analysis. This supports the use of major dietary patterns identified using a FFQ in this adolescent cohort.

There has been recent increased interest in utilizing motivational interviewing (MI) to increase adolescent readiness to quit smoking, but attempts to impact quit rates have thus far been discouraging. A better understanding of factors associated with adolescent readiness to quit smoking prior to receiving any intervention may provide guidance when tailoring future MI interventions in order to increase their effectiveness with this population. Adolescent smokers (N=191) who had been admitted to a psychiatric hospital and enrolled in a clinical trial evaluating MI completed questionnaires that assessed smoking behavior and variables thought to be related to smoking. Confidence to quit smoking and negative beliefs about smoking were significant predictors of adolescents' baseline readiness to quit smoking. The failure to demonstrate relationships between health consequences and readiness suggest that caution may be warranted in the use of feedback, a common component of MI-based interventions. Such feedback tends to focus on health consequences, which was unrelated to adolescent baseline readiness to change smoking behavior in the current study. Parallels between current results and the Theory of Planned Behavior are discussed in consideration of developing more effective MI-based interventions for adolescent smokers.

OBJECTIVE To examine the dietary and activity correlates of sugar-sweetened beverage (SSB) consumption in middle and high-school children. METHODS Data were obtained from a cross-sectional survey of 15,283 middle and high school children in Texas, USA. Consumption of sodas and consumption of non-carbonated flavored and sports beverages (FSB) were examined separately for their associations with level of (a) unhealthy foods (fried meats, fries, desserts) and (b) healthy foods (vegetables, fruit, and milk) (c) physical activity including usual vigorous physical activity, and participation in organized physical activity, and (d) sedentary activity, including hours spent on TV, the computer, and videogames. RESULTS In both sexes, consumption of soda and FSB were systematically associated with a number of unhealthy dietary practices, as well as with sedentary behaviors. However, consumption of flavored and sports beverages showed significant positive graded associations with several healthy dietary practices and level of physical activity, while soda consumption showed no such associations with healthy behaviors. CONCLUSIONS Consumption of flavored and sports beverages coexists with healthy dietary and physical activity behaviors, suggesting popular misperception of these beverages as consistent with a healthy lifestyle. Assessment and obesity-prevention efforts targeting SSB need to distinguish between flavored and sports beverages from sodas. PMID:20876172

Sexualizing media content is prevalent in various media types. Sexualizing media messages and portrayals emphasize unattainable body and appearance ideals as the primary components of sexual desirability. The internalization of these ideals is positively related to self-objectification and sexual body consciousness. In turn, self-objectification and sexual body consciousness affect adolescents' sexual behavior, albeit in opposing directions. While objectifying self-perceptions are linked to higher levels of sexual behavior, body consciousness during physical intimacy is linked to lower levels of sexual behavior. Based on this knowledge, the present three-wave panel study of 824 Belgian, predominant heterosexual adolescents (M age = 15.33; SD = 1.45) proposes a dual-pathway model that investigates two different pathways through which the internalization of media ideals may impact adolescents' sexual behavior. An inhibitory pathway links media internalization to lower levels of sexual behavior through sexual body consciousness, and a supportive pathway links media internalization to higher levels of sexual behavior through self-objectification. Structural equation analyses supported the proposed dual-pathway, showing that the impact of media internalization on adolescents' sexual behavior proceeds through an inhibitory pathway and a supportive pathway. Regarding the supportive pathway, media internalization (W1) positively predicted sexual behavior (W3), through valuing appearance over competence (W2). Regarding the inhibitory pathway, media internalization (W1) positively predicted body surveillance, which, in turn, positively predicted sexual body consciousness (all W2). Sexual body consciousness (W2) is negatively related to sexual behavior (W3). From a sexual developmental perspective, these findings emphasize the importance of guiding adolescents in interpreting and processing sexualizing media messages.

We examined multi-system influences on risky sexual behavior measured by cumulative sexual risk index and number of nonromantic sexual partners among 4,465 single, sexually experienced adolescents. Hierarchical Poisson regression analyses were conducted with Wave I-II data from the National Longitudinal Study of Adolescent Health. Individual and family factors predicted both outcome measures. Neighborhood set predicted cumulative sexual risk index only, and peer factors predicted the number of nonromantic sexual partners only. School set did not predict either outcome. There were significant associations among risky sexual behavior, drug use, and delinquent behaviors. The results highlight the need for multifaceted prevention programs that address relevant factors related to family, peer and neighborhood influence as well as individual factors among sexually active adolescents.

Robust associations have been identified between impulsive personality characteristics and cigarette smoking during adolescents, indicating that impulsive behavior may play an important role in the initiation of cigarette smoking. The present study extended this research by using laboratory behavioral assessments to explore relationships between three specific dimensions of impulsive behavior (impulsive decision-making, inattention, and disinhibition) and adolescent cigarette smoking. Participants were male and female adolescent smokers (n = 50) and nonsmokers (n = 50). Adolescent smokers were more impulsive on a measure of decision-making; however, there were significant smoking status by gender interaction effects for impulsive inattention and disinhibition. Male smokers were most impulsive on the measure of inattention, but male smokers were least impulsive on the measure of disinhibition. Correlations between biomarkers of smoking and impulsive inattention and disinhibition were found for females but not males. The current findings, coupled with previous findings (Reynolds et al., 2007), indicate there may be robust gender difference in associations between certain types of impulsive behavior and cigarette smoking during adolescence.

Adolescent cigarette smoking rates remain a significant public health concern, and as a result there is a continued need to understand factors that contribute to an adolescent's ability to reduce or quit smoking. Previous research suggests that impulsive behavior may be associated with treatment outcomes for smoking. The current research (N = 81) explored 3 dimensions of impulsive behavior as predictors of treatment response from a social-cognitive type program for adolescent smokers (i.e., Not On Tobacco; N-O-T). Measures included laboratory assessments of delay discounting, sustained attention, and behavioral disinhibition. A self-report measure of impulsivity was also included. Adolescent smokers who had better sustained attention were more likely to reduce or quit smoking by the end of treatment. No other measures of impulsivity were significantly associated with treatment response. From these findings, an adolescent smoker's ability to sustain attention appears to be an important behavioral attribute to consider when implementing smoking cessation programs such as N-O-T.

Recently, self-injury is drawing the attention of researchers and clinicians. The purpose of this study was to investigate the prevalence and psychological characteristics of adolescents who engage in self-harm and to examine the risk factors for engaging in this harmful behavior among Korean mid-adolescents. Participants were 784 adolescents aged 13-15 years. They completed self-report questionnaires that assessed (1) Non-Suicidal Self-Injury: the Self-Harm Questionnaire, Toronto Alexithymia Scale; (2) depression: Children's Depression Inventory; (3) adolescent-parent relationship: Parental Bonding Instrument; (4) peer attachment: Inventory of Parent and Peer Attachment; and (5) academic stress. Overall, 12.4% (n=97) of participants reported engaging in self-destructive behavior at least once in their lives. The primary reason for engaging in self-harm was to regulate negative emotions such as anger and sadness. As expected, the self-harm group showed statistically significant higher levels of academic stress, alexithymia, depression, and poor relationships with their parents and peers. Stepwise multiple regression analysis showed that alexithymia, depression, and peer relations were significant predictors of self-harming behavior. Given that the primary reason for engaging in self-harm is to cope with negative emotions, mental health professionals in school settings should regularly evaluate self-injurious behavior and provide prevention programs for adolescents at risk.

This study examined parental, peer, and media influences on Taiwanese adolescents' attitudes toward premarital sex and intent to engage in sexual behavior. Participants included a convenience sample of 186 adolescents aged 13-15 recruited from two middle schools in Taiwan. Parental influence was indicated by perceived parental disapproval toward premarital sex and perceived peer sexual behavior was used to measure peer influence. Media influence was measured by the adolescents' perception of whether the media promotes premarital sex. We conducted structural equation modeling to test a hypothesized model. The findings suggested that the perceived sexual behavior of peers had the strongest effect on Taiwanese adolescents' sexual attitudes and behavioral intent, while parental disapproval and media influence also significantly contributed to adolescents' sexual attitudes and intent to engage in sex. School nurses are in an ideal position to coordinate essential resources and implement evidence-based sexually transmitted infection and HIV/AIDS prevention interventions that address issues associated with the influence of parents, peers, and media.

Adolescence is a critical transition period, during which fundamental changes prepare the adolescent for becoming an adult. Heuristic models of the neurobiology of adolescent behavior have emerged, promoting the central role of reward and motivation, coupled with cognitive immaturities. Here, we bring focus to two basic sets of processes, attention and conditioning, which are essential for adaptive behavior. Using the dual-attention model developed by Corbetta and Shulman (2002), which identifies a stimulus-driven and a goal-driven attention network, we propose a balance that favors stimulus-driven attention over goal-driven attention in youth. Regarding conditioning, we hypothesize that stronger associations tend to be made between environmental cues and appetitive stimuli, and weaker associations with aversive stimuli, in youth relative to adults. An attention system geared to prioritize stimulus-driven attention, together with more powerful associative learning with appetitive incentives, contribute to shape patterns of adolescent motivated behavior. This proposed bias in attention and conditioning function could facilitate the impulsive, novelty-seeking and risk-taking behavior that is typical of many adolescents. PMID:21977221

Background Added sugar intake in the form of sugar-sweetened beverages (SSB) has been considered a contributor to weight gain and cardiometabolic dysfunction in adults and youth. Adolescents are some of the highest consumers of added sugars, taking in ~16% of their total calories from added sugars with ~40% of these calories coming from SSB. Youth’s food preferences and self-regulation of dietary intake can be influenced by parents. Objective To evaluate the Theory of Planned Behavior’s (TPB) effectiveness in understanding and predicting adolescents' SSB consumption, identify which constructs are the most important when evaluating SSB consumption in adolescents, and determine if and how adolescents' beverage choices are influenced by parents' reactions to their beverage choices. Design Measurements for this cross-sectional study included four record-assisted 24-hour dietary recalls and responses to a SSB-specific TPB questionnaire from 100 adolescents. Consenting parents completed a beverage intake questionnaire, a TPB questionnaire, and Parent Response to Beverage Choice Questionnaire. Results The TPB explained 34% of the variance in adolescents' and parents' intention to limit SSB to less than one cup per day. Parents' perceived behavioral control (b=1.35, p=0.002) and adolescents' subjective norms (b=0.57, p=0.001) were the strongest predictors of intention, and intention was the strongest predictor of SSB consumption in both adolescents and parents (b=−37, p=0.026, b=−49, p=0.003). The TPB explained more variance in parent SSB consumption (R2=0.38) than adolescents (R2=0.22). Parents did more discouraging of SSB and encouraging of non-SSB. Adolescents' intention to limit SSB moderated the relationship between parents' reactions encouraging SSB and adolescents' predicted SSB consumption (p=0.021). Conclusions The TPB explained a small, but significant amount of variance in adolescents' SSB consumption. When addressing adolescent SSB intake, people in

The current study examined the mediating role of adolescents' personal values on the relation between maternal and peer expectations for prosocial behaviors and adolescents' self-reported prosocial and antisocial behaviors. One hundred thirty-four adolescents (mean age = 16.22 years, 54% girls) completed measures of their own values and behaviors, as well as their perceptions of the positive expectations that their mother and their best friend(s) had for their (the adolescents') prosocial behaviors. Stepwise regression analyses suggested that adolescents' personal prosocial values mediated the relation between adolescents' perceptions of both maternal and peer expectations and adolescents' prosocial behaviors. In addition, for boys, perceptions of positive peer expectations were directly and negatively related to antisocial behaviors. The current study has important implications for parents, educators, and practitioners who are concerned about promoting adolescents' positive behaviors and discouraging negative behaviors.

The percentage of people with mental retardation in the general population is estimated at about 2.3%, with adolescence (15-20 years) constituting the development period during which a peak in rates of mental retardation is observed. The increased prevalence of adolescence may be explained from the fact that the specified requirements of the school initially, and society later, inevitably lead to comparative evaluation of the teen with mental retardation in relation to peers, thus making mental retardation more apparent. Adolescents with mental retardation face a number of physical and psychological needs which are not often distinguishable and as a consequence undergo the deterioration of their already burdened quality of life. In particular, mental health problems occur 3 to 4 times more often in adolescents with mental retardation compared with adolescents of the general population. This review presents the most recent epidemiological findings regarding the correlation between behavioral disorders, substance use and the possible comorbidity in adolescents with intellectual disability, both at community level and residential care level. Epidemiological data indicate that behavioral disorders are among the most common types of psychopathology in mentally retarded adolescents with the severity and symptoms varying depending on the personal characteristics of each adolescent. Regarding substance use, the available data show that the rates of substance use (alcohol, smoking, illicit drugs) are lower in this specific population group but the differences over the last years tend to be eliminated. Finally, according to the few surveys that were examined referring to the comorbidity of behavioral disorders and substance use in adolescents with intellectual disability, the results were contradictory. Specifically, while behavioral disorders continued to be one of the most common types of psychopathology, the related substances disorders indicated lower rates compared to

To identify the role of dietary habits (type of diet, skipping meals, snacking in-between meals and frequency of visits to fast food restaurants) in caries occurrence and severity. To explore the correlation between frequency of intake of selected foods and dental caries. A cross-sectional study was carried out on adolescent children (n = 916) of age 13-19, following a two-stage random sampling technique. Data were collected using a pretested questionnaire. Questionnaire included demographic details, dietary habits of children and food frequency table that listed selected food items. The dependent variable-dental caries was measured using the decayed, missing, filled teeth (DMFT) index. The prevalence of dental caries in this study population was 36.7% (95% confidence interval: 33.58-39.82). The mean DMFT was 1.01 (±1.74). No statistically significant difference found between caries occurrence and type of diet (P = 0.07), skipping meals (P = 0.86), frequency of eating in fast food stalls (0.86) and snacking in between meals (0.08). Mean DMFT values were higher among nonvegetarians and among children who had the habit of snacking in between meals. Frequency of intake of selected food items showed that mean frequency intake of carbonated drinks and confectionery was higher among children who presented with caries when compared to caries-free children (P = 0.000). Significant correlation found between mean DMFT and mean frequency intake of carbonated drinks and confectionery. Odds ratios were calculated for the same for frequency ≥4 times/day for confectionery and ≥4/week for carbonated drinks and results discussed. Frequent intake of carbonated drinks and confectionery is harmful to oral health that eventually reflects on general health. Educating the adolescent children on healthy dietary habits should be put in the forefront.
Background There is a great need for dietary assessment methods that suit the adolescent lifestyle and give valid intake data. Objective To develop a mobile phone app and evaluate its ability to assess energy intake (EI) and total energy expenditure (TEE) compared with objectively measured TEE. Furthermore, to investigate the impact of factors on reporting accuracy of EI, and to compare dietary intake with a Web-based method. Methods Participants 14 to 16 years of age were recruited from year nine in schools in Gothenburg, Sweden. In total, 81 adolescents used the mobile phone app over 1 to 6 days. TEE was measured with the SenseWear Armband (SWA) during the same or proximate days. Individual factors were assessed with a questionnaire. A total of 15 participants also recorded dietary intake using a Web-based method. Results The mobile phone app underestimated EI by 29% on a group level (P<.001) compared to TEE measured with the SWA, and there was no significant correlation between EI and TEE. Accuracy of EI relative to TEE increased with a weekend day in the record (P=.007) and lower BMI z-score (P=.001). TEE assessed with the mobile phone app was 1.19 times the value of TEE measured by the SWA on a group level (P<.001), and the correlation between the methods was .75 (P<.001). Analysis of physical activity levels (PAL) from the mobile phone app stratified by gender showed that accuracy of the mobile phone app was higher among boys. EI, nutrients, and food groups assessed with the mobile phone app and Web-based method among 15 participants were not significantly different and several were significantly correlated, but strong conclusions cannot be drawn due to the low number of participants. Conclusions By using a mobile phone dietary assessment app, on average 71% of adolescents’ EI was captured. The accuracy of reported dietary intake was higher with lower BMI z-score and if a weekend day was included in the record. The daily question in the mobile phone app

Background Among adults, the Mediterranean dietary pattern (MDP) is inversely related to body mass index (BMI). Data are lacking on adherence to the MDP among youth in the United States and whether the MDP is related to weight change in that group. Objective To assess whether adherence to the MDP was associated with BMI change among adolescents. To examine temporality we studied the association between baseline and 2–3 year changes in adherence to the MDP with concurrent changes in BMI, as well as subsequent changes in BMI over a 7-year period. Methods We prospectively followed 6 002 females and 4 916 males in the Growing Up Today Study 2, aged 8–15 in 2004, living across the United States. Data were collected by questionnaire in 2004, 2006, 2008, and 2011. Dietary intake was assessed by the Youth/Adolescent Questionnaire. The KidMed Index was derived to measure the adherence to the MDP. We used generalized estimating equations with repeated measures within subjects to assess the association between MDP and BMI change. Results A two-point increment in the KidMed Index was independently associated with a lower gain in BMI (−0.04 kg/m2; p=0.001). A greater increase in adherence to the KidMed Index was independently related to a lower gain in BMI in both the concurrent (p-for-trend<0.001) and the subsequent period (p-for-trend=0.002). Conclusions Adherence to MDP was inversely associated with change in BMI among adolescents. 2-year improvement in adherence to MDP was independently associated with less steep gain in the BMI in both the concurrent and the subsequent period.

Obesity has become a public health problem in adolescents and could be a risk factor for both short-term and long-term health consequences. This study aimed to evaluate the relationship of Dietary Guidelines for Americans Adherence Index (DGAI), Healthy Eating Index-2005 (HEI-2005) and Healthy Eating Index-2010 (HEI-2010) with risk of obesity associated phenotypes in Tehranian adolescents. This cross-sectional study was conducted within the framework of the Tehran Lipid and Glucose Study, on 722 adolescents, aged 10–19 years. Usual dietary intakes were assessed by a food frequency questionnaire, and diet quality scores were obtained based on DGAI, HEI-2005 and HEI-2010. General obesity and cardio metabolic risk factors were defined according to the Centers of Disease Control and Prevention and de’Ferranti cut-offs, respectively. After adjusting for age, sex, energy intake and physical activity, compared to those in the lowest quartile, participants in the highest quartile of HEI-2010 had lower risk of general obesity (OR: 0.62; 95% CI: 0.38–0.93; Ptrend = 0.03) and central obesity (OR: 0.63; 95% CI: 0.44–0.95; Ptrend = 0.04). No association was observed between different types of obesity and scores of other diet quality indices. In conclusions, considering the role of HEI-2010 in decreasing the risk of obesity, these findings suggest that HEI-2010 may be useful for assessing diet-related progress in obesity prevention efforts.

This study explored the association between dietary habits and overweight and obesity in adolescents from Xi'an City, China. A cross-sectional sample of 1804 adolescents was recruited in 2004 from 30 junior high schools in six districts of Xi'an City, northwest China. Weight and height was measured and eating habits assessed using a self-administered questionnaire. Logistic regression was used to identify dietary patterns associated with overweight and obesity and adjusted for socio-demographic factors. Consumption of foods and beverages outside three main meals, and potato chips was more popular in boys than in girls, while girls consumed more fried food and soft drinks than boys. In boys, an increased consumption of soft drinks was associated with increased risk of overweight and obesity (1100 mL/day, OR: 1.9, 95% CI: 1.1-3.8), while consuming preserved fruit was associated with decreased risk (OR: 0.6, 95% CI: 0.5-0.9). In girls, having breakfast outside the home (OR: 1.7, 95% CI: 1.1-2.3) and an increased consumption of energy-dense foods (OR: 1.7, 95% CI: 1.04-2.9), was associated with increased risk of overweight and obesity, while frequently having foods and beverages outside the three main meals (OR: 0.6, 95% CI: 0.4-0.9) was associated with decreased risk. The consumption of breakfast outside the home, soft drinks and energy-dense fast foods were positively associated with overweight and obesity in adolescents. Future health education programs to prevent excess weight gain should target such unhealthy eating habits.

We carried out a cross sectional study to detect emotional and behavioral problems among adolescents who smoke and their help-seeking behavior. This study was conducted in Sarawak, East Malaysia, between July and September 2006. Emotional and behavioral problems were measured using the Youth Self-Report (YSR/11-18) questionnaire; help seeking behavior was assessed using a help-seeking questionnaire. Three hundred ninety-nine students participated in the study; the smoking prevalence was 32.8%. The mean scores for emotional and behavioral problems were higher among smokers than non-smokers in all domains (internalizing, p = 0.028; externalizing, p = 0.001; other behavior, p = 0.001). The majority of students who smoked (94.7%) did not seek help from a primary health care provider for their emotional or behavioral problems. Common barriers to help-seeking were: the perception their problems were trivial (60.3%) and the preference to solve problems on their own (45.8%). Our findings suggest adolescent smokers in Sarawak, East Malaysia were more likely to break rules, exhibit aggressive behavior and have somatic complaints than non-smoking adolescents. Adolescent smokers preferred to seek help for their problems from informal sources. Physicians treating adolescents should inquire about smoking habits, emotional and behavioral problems and offer counseling if required.

Adolescent risk behavior remains prevalent and contributes to numerous social problems and growing health care costs. Contrary to popular perception, adolescents in rural areas engage in risky behaviors at least as much as youth from urban or suburban settings. Little research, however, focuses on risk behavior prevention in the rural context.…

Understanding behavioral resilience among at-risk adolescents may guide public policy decisions and future programs. We examined factors predicting behavioral resilience following intrauterine substance exposure (IUSE) in a prospective longitudinal birth-cohort study of 136 early adolescents (age 12.4–15.9) at-risk for poor behavioral outcomes. We defined behavioral resilience as a composite measure of lack of early substance use initiation (before age 14), lack of risky sexual behavior, or lack of delinquency. IUSEs included in this analysis were cocaine (IUCE), tobacco (IUTE), alcohol (IUAE), and marijuana (IUME). We recruited participants from Boston Medical Center as mother-infant dyads between 1990 and 1993. The majority of the sample was African-American/Caribbean (88%) and 49% female. In bivariate analyses, none and lower IUCE level predicted resilience compared to higher IUCE, but this effect was not found in an adjusted model. Instead, strict caregiver supervision (adjusted odds ratio (AOR)=6.02, 95% confidence interval (CI)=1.90–19.00, p=0.002), lower violence exposure (AOR=4.07, 95% CI=1.77–9.38, p<0.001), and absence of intrauterine tobacco exposure (AOR=3.71, 95% CI= 1.28–10.74, p=0.02) predicted behavioral resilience. In conclusion, caregiver supervision in early adolescence, lower violence exposure in childhood, and lack of intrauterine tobacco exposure predict behavioral resilience among a cohort of early adolescents with significant social and environmental risk. Future interventions should work to enhance parental supervision as a way to mitigate the effects of adversity on high-risk groups of adolescents. PMID:26076097

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

Hispanic adolescents reported a higher annual prevalence of use of nearly all major drugs compared to non-Hispanic White and African American adolescents. Cultural or minority stressors, such as those related to the acculturation process, discrimination, immigration, poverty, and community violence, have been implicated in these outcomes. Unfortunately, few studies have examined how these stressors may have a differential or additive effect when considered simultaneously. The current study examined the relation between stress and multiple substance use behaviors in a sample of Hispanic adolescents (n=1036), age 11–19 years old. Latent class analysis identified subgroups of Hispanic adolescents based on combinations of substance use behaviors. General linear models were used to examine mean differences by class among the eight domains of stress. Fit statistics revealed a six-class structure: no substance use risk, predominately alcohol use, low polysubstance use, high polysubstance use, illicit drug use, and predominately marijuana use. Differences in stress across the six classes were identified for four of the eight domains: family economic, acculturation gap, community and gang, and family and drug stress. The effect sizes revealed the largest mean differences in stress between the no substance use group and the two polysubstance use groups and between the no risk group and alcohol use group. The findings from this study support the use of interventions that target stress to affect multiple substance use behaviors in Hispanic adolescents. PMID:26319617

This study explores the influence of health behaviors and individual attributes on adolescent overweight and obesity using data from Wave II (Add Health). Structural equation model/path analysis using maximum likelihood estimation was utilized to analyze the relationships of health behaviors and attributes with obesity. Results of the model reveal that the causal paths (adolescents' attributes and health behaviors) for overweight and obesity were different for African American and Caucasian adolescents. Generally, African Americans were more susceptible to overweight and obesity than Caucasians. Although increasing levels of vigorous physical activities lowers the risk for obesity among African American and Caucasian adolescents alike, low family SES and being sedentary were associated with overweight and obesity among Caucasians. No significant associations were found among African Americans. Increased hours of sleep at night relate positively with obesity among African Americans. These findings suggest important elements in the consideration of race in developing effective intervention and prevention approaches for curbing the obesity epidemic among U.S. adolescents.

In the last two decades the incidence of adolescent suicides has been very high (though it has been on the decrease in the U.S.A. over the last four years), giving rise to a multitude of empirical and theoretical studies. The extensive knowledge that has accumulated regarding adolescent suicidal behavior has led to a more differentiated attitude. Many studies try to clarify specific needs, motivations and the conceptualization of death and suicide in various adolescent subgroups (minorities, females, homosexuals), thereby enabling more specific and exact methods of evaluation, prevention and intervention. Adolescent girls' suicidal behavior is different in many aspects from boys' suicidal behavior: Girls mortality rate from suicide is a 3-5 times lower rate than boys, but their attempted suicide rate is four to hundreds time higher. Girls suicide mainly by drugs and their suicide is mainly in reaction to interpersonal difficulties. Their motivation is often a cry for help. The comorbidity of suicide and depression is much higher for adolescent girls than boys. These differences generate a different understanding and separate treatment strategies. Two theoretical approaches that may explain the profile which characterizes suicidal girls will be presented. One has a psychological developmental context, and the other a social cultural context. Implications for specific prevention measures include legal action on pack sizes of analgesics, compulsory registration of attempted suicide and more gender specific treatment and prevention programs.

Being born prematurely associates with greater cardiovascular disease (CVD) risk in adulthood. Less understood are the unique and joint associations of dietary patterns and behaviors to this elevated risk among adults who are born prematurely. We aimed to model the associations between term status, dietary and lifestyle behaviors with CVD risk factors while accounting for the longitudinal effects of family protection, and medical or environmental risks. In wave-VIII of a longitudinal study, 23-year olds born prematurely (PT-adults, n = 129) and full term (FT-adults, n = 38) survey-reported liking for foods/beverages and activities, constructed into indexes of dietary quality and sensation-seeking, dietary restraint and physical activity. Measured CVD risk factors included fasting serum lipids and glucose, blood pressure and adiposity. In bivariate relationships, PT-adults reported lower dietary quality (including less affinity for protein-rich foods and higher affinity for sweets), less liking for sensation-seeking foods/activities, and less restrained eating than did FT-adults. In comparison to nationally-representative values and the FT-adults, PT-adults showed greater level of CVD risk factors for blood pressure and serum lipids. In structural equation modeling, dietary quality completely mediated the association between term status and HDL-cholesterol (higher quality, lower HDL-cholesterol) yet joined term status to explain variability in systolic blood pressure (PT-adults with lowest dietary quality had highest blood pressures). Through lower dietary quality, being born prematurely was indirectly linked to higher cholesterol/HDL, higher LDL/HDL and elevated waist/hip ratios. The relationship between dietary quality and CVD risk was strongest for PT-adults who had developed greater cumulative medical risk. Protective environments failed to attenuate relationships between dietary quality and elevated CVD risk among PT-adults. In summary, less healthy dietary

Specific targets for most obesity candidate genes discovered by genomewide association studies remain unknown. Such genes are often highly expressed in the hypothalamus, indicating their role in energy homeostasis. We aimed to evaluate the associations of selected gene variants with adiposity and dietary traits. Anthropometric parameters, fat mass, dietary intake (total energy, fat, protein, carbohydrate, fiber, and calcium) and 10 gene variants (in/near TMEM18, SH2B1, KCTD15, PCSK1, BDNF, SEC16B, MC4R and FTO) were analyzed in 1953 Czech individuals aged 10.0 to 18.0 years (1035 nonoverweight and 918 overweight: body mass index [BMI] ≥90th percentile). Obesity risk alleles of TMEM18 rs7561317, SEC16B rs10913469, and FTO rs9939609 were related to increased body weight and BMI (P < .005). The FTO variant also showed a significant positive association with waist circumference and fat mass (P < .001). Overweight adolescents had a lower total energy intake (P < .001) but a higher percentage of fat (P = .009) and protein intake (P < .001) than the nonoverweight subjects. There was also a lower calcium intake in the overweight group (P < .001). An association with at least one component of dietary intake was found in 3 of 10 studied gene variants. The MC4R rs17782313 was associated negatively with protein (P = .012) and positively associated with fiber (P = .032) intakes. The obesity risk alleles of BDNF rs925946 and FTO rs9939609 were related to a lower calcium intake (P = .001 and .037). The effects of FTO and MC4R variants, however, disappeared after corrections for multiple testing. Our results suggest that the common BDNF variant may influence dietary calcium intake independent of BMI.

Family factors have been widely implicated in the development of adolescent drinking behaviors. These include parental attachment and parental rules concerning drinking behaviors. Moreover, throughout adolescence attachment to parents gives way to attachment to peers, and parental rules about alcohol use become less strict. The present study examined the relationship between parental and peer attachment, parental rules on drinking and alcohol use in a large sample (n = 1,724) of adolescents in the United Kingdom. Controlling for school grade (proxy for age), sex and the non-independence of respondents (clustering at school level) results showed that scores on a parental rules on drinking questionnaire were a significant statistical predictor when comparing moderate drinkers and abstainers, as well as moderate drinkers and problematic drinkers. Scores on both attachment scales were also significant, but only in the comparison between moderate and problematic drinkers, with lower attachment to parents and higher attachment to peers associated with problematic drinking.

OBJECTIVES: This study aimed to examine the prevalence of sexting behaviors (sexually explicit messages and/or pictures) among an at-risk sample of early adolescents as well as the associations between sexting behaviors and sexual behaviors, risk-related cognitions, and emotional regulation skills. It also aimed to determine whether differences in risk were associated with text-based versus photo-based sexts. METHODS: Seventh-grade adolescents participating in a sexual risk prevention trial for at-risk early adolescents completed a computer-based survey at baseline regarding sexting behavior (having sent sexually explicit messages and/or pictures), sexual activities, intentions to have sex, perceived approval of sexual activity, and emotional regulation skills. RESULTS: Twenty-two percent of the sample reported having sexted in the past 6 months; sexual messages were endorsed by 17% (n = 71), sexual messages and photos by 5% (n = 21). Pictures were endorsed significantly more often by females (χ2 = 7.33, P = .03) and Latinos (χ2 = 7.27, P = .03). Sexting of any kind was associated with higher rates of engaging in a variety of sexual behaviors, and sending photos was associated with higher rates of sexual activity than sending text messages only. This was true for a range of behaviors from touching genitals over clothes (odds ratio [OR] = 1.98, P = .03) to oral sex (OR = 2.66, P < .01) to vaginal sex (OR = 2.23, P < .01). CONCLUSIONS: Sexting behavior (both photo and text messages) was not uncommon among middle school youth and co-occurred with sexual behavior. These data suggest that phone behaviors, even flirtatious messages, may be an indicator of risk. Clinicians, parents, and health programs should discuss sexting with early adolescents. PMID:24394678

Engagement in problem behaviors during adolescence has important implications for academic achievement and psychosocial well-being. The current study examined engagement in problem behavior across the transition from pregnancy to parenthood among a sample of 204 Mexican-origin adolescent mothers (ages 15-18 years; Mage = 16.8 at Time 1) to better understand the behaviors in which this sample engaged and how engagement changed over this period of transition. Descriptively, this sample engaged in relatively low levels of problem behaviors. Frequently endorsed problem behaviors included missing school or work without an excuse, lying or disobeying parents, and engagement in dangerous behaviors for a thrill; notably, substance use was not a frequently endorsed behavior until the final waves of the study, when most of the mothers were of legal age for these behaviors. Further, latent growth curve modeling revealed a non-linear pattern of change in problem behaviors, such that engagement decreased substantially from the third trimester of pregnancy to 36 months postpartum, but then leveled off between 36 and 48 months postpartum. Findings suggest a need for future research to better understand how engagement in problem behaviors changes pre- to post-pregnancy, and how to best support the decrease in problem behaviors once a pregnancy has been detected.

The diversity of the associations of dietary glycaemic index (GI) and glycaemic load (GL) with dietary intake and body fatness observed in epidemiological studies may be partly due to the differences in underlying dietary intake patterns. We examined the cross-sectional associations of dietary GI and GL with food and nutrient intakes and indices of body fatness in 818 children aged 4-10 years and 818 adolescents aged 11-18 years in Britain, based on the data from the National Diet and Nutrition Survey. Dietary intake was assessed using a 7 d weighed dietary record. Overweight was defined as BMI ≥ 85th percentile of the age- and sex-specific British growth reference data. Central obesity was defined as waist:height ratio (WHtR) ≥ 0·5 (adolescents only). Breads, breakfast cereals and potatoes were the positive predictive food groups for dietary GI, while dairy products, fruit juice, other cereals and fruit were the negative predictors. Dietary GL was closely correlated with carbohydrate intake. Dietary GI showed no associations with overweight or central obesity. Conversely, dietary GL showed an independent association with a higher risk of overweight in children and a higher risk of central obesity (but not overweight) in adolescents. However, dietary GI and GL were not associated with BMI z-score in children and adolescents or WHtR in adolescents. In conclusion, the present study showed that dietary GL was independently associated with overweight in children and with central obesity in adolescents. Nevertheless, given no associations when body fatness measures were treated as continuous variables, the results must be interpreted cautiously.

Dietary diversity often varies inversely with prey resource abundance. This pattern, although typically measured at the population level, is usually assumed to also characterize the behavior of individual animals within the population. However, the pattern might also be produced by changes in the degree of variation among individuals. Here we report on dietary and associated behavioral changes that occurred with the experimental translocation of sea otters from a food-poor to a food-rich environment. Although the diets of all individuals were broadly similar in the food-rich environment, a behaviorally based dietary polymorphism existed in the food-poor environment. Higher dietary diversity under low resource abundance was largely driven by greater variation among individuals. We further show that the dietary polymorphism in the food-poor environment included a broad suite of correlated behavioral variables and that the individuals that comprised specific behavioral clusters benefited from improved foraging efficiency on their individually preferred prey. Our findings add to the growing list of examples of extreme individuality in behavior and prey choice within populations and suggest that this phenomenon can emerge as a behavioral manifestation of increased population density. Individuality in foraging behavior adds complexity to both the fitness consequences of prey selection and food web dynamics, and it may figure prominently as a diversifying process over evolutionary timescales.

In order to identify risk of inadequate intake of calories and nutrients during pregnancy, 75 pregnant adolescents (14 to 18 years old) apparently healthy, from low socioeconomic level, in their first prenatal control (12 weeks) were studied by two 24 hour recalls and a food frequency questionnaire at each trimester. Nutritional status was assessed by body mass index (pregestation weight/height) and classified according to American Medicine Institute reference. Paired t-test, frequency distribution and ANOVA were used for statistical analysis. Low weight was found in 34.6% of adolescent at the first visit and 5.3% were overweight. Even though, caloric intake was below recommendation, significant increases were observed between first and second trimester for energy, carbohydrates, niacin and zinc (p < 0.001) and for fat, proteins, riboflavin, thiamin, vitamin C, calcium and iron (p < 0.05). From second to third trimester, differences (p < 0.05) were significant only for vitamin A. Between first and third trimester, differences were significant (p < 0.05) for energy, proteins, carbohydrates, niacin, riboflavin, zinc and for thiamin, vitamin A and calcium (p < 0.05). A high proportion of pregnant adolescent did not reach recommendations for energy, folate, calcium and zinc. Food intake pattern did not change significantly among trimesters. Mean total weight gain was 9.2 kg and 0.412 +/- 0.4 g/week. Newborn's mean weight was 3.221 +/- 418 grams. It is concluded that adolescents are at high nutritional risk and deficiency of dietary intake should be followed. Attention should be addressed from the preconceptional period to postpartum in order to improve maternal and fetal conditions.

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.

The author examined the association between emotional autonomy and problem behavior among Chinese adolescents living in Hong Kong. The respondents were 512 adolescents, 16 to 18 years of age, who were interviewed for a cross-sectional study. Three dimensions of emotional autonomy including individuation, nondependency on parents, and de-idealization of parents were significantly and positively correlated with the amount of problem behavior the participants engaged in during the past 6 months. Using a simple linear multiple regression model, the author found that problem behavior was associated with only one aspect of emotional autonomy-individuation. Results indicated that the relationship between problem behavior and three aspects of emotional autonomy was similar in both individualistic and collectivistic societies.

Headache is the most frequent neurological symptom and the most prevalent pain in children and adolescents, and constitutes a serious health problem that may lead to impairment in several areas. Psychosocial factors, social environment, life events, school and family stressors are all closely related to headaches. A multidisciplinary strategy is fundamental in addressing headache in children and adolescents. Applying such a strategy can lead to reductions in frequency and severity of the pain, improving significantly the quality of life of these children.It has been demonstrated that behavioral intervention is highly effective, especially in the treatment of paediatric headache, and can enhance or replace pharmacotherapy, with the advantage of eliminating dangerous side effects and or reducing costs. Behavioral interventions appear to maximize long-term therapeutic benefits and improve compliance with pharmacological treatment, which has proven a significant problem with child and adolescent with headache.The goal of this review is to examine the existing literature on behavioral therapies used to treat headache in children and adolescents, and so provide an up-to-date picture of what behavioral therapy is and what its effectiveness is.

This paper attempts to account for the upsurge of adolescents' problem behavior in high-income countries in terms of Lifton's paradigm of symbolic immortality. Whilst most of the works dealing with this subject focus on the level of the individual adolescent and his or her surrounding, Lifton shows that societal processes can affect the individual. Drawing upon his approach, it was argued that desymbolization,--the collapse of society's symbols system--produces "divided selves," individuals who harbor an 'aggressor-victim double' in their psyche, wherein an internal conflict between the aggressor and the victim engenders self-destructive impulses. In this study it is hypothesized that problem behaviors are external manifestations of underlying self-destructiveness. Thirty-four Jewish-Israeli adolescents involved in sexual promiscuity, drug abuse, anorexia nervosa, and violence were interviewed. It was found that despite individual and social dissimilarities, and the different problem behaviors, the participants were marked by inner-directed destructiveness as well as a sense of meaninglessness of life and lack of symbolic relationship to what transcends their here-and-now selves. Significantly, violent adolescents whose aggression is other-directed were found to be marked by underlying self-directed aggression as well. If the findings of this study are representative of Israeli society at large or of other affluent societies, then the epidemic proportions of youth problem behavior may indicate that these societies are undergoing desymbolization, a psychocultural breakdown.

Prenatal alcohol exposure can have serious and permanent adverse effects. The developing brain is the most vulnerable organ to the insults of prenatal alcohol exposure. A behavioral phenotype of prenatal alcohol exposure including conduct disorders is also described. This study on a sample of Brazilian adolescents convicted for criminal behavior aimed to evaluate possible clinical features of Fetal Alcohol Syndrome (FAS). These were compared to a control group of school adolescents, as well as tested for other environmental risk factors for antisocial behavior. A sample of 262 institutionalized male adolescents due to criminal behavior and 154 male students aged between 13 and 21 years comprised the study population. Maternal use of alcohol was admitted by 48.8% of the mothers of institutionalized adolescents and by 39.9% of the school students. In this sample of adolescents we could not identify individual cases with a clear diagnosis of FAS, but signs suggestive of FASD were more common in the institutionalized adolescents. Social factors like domestic and family violence were frequent in the risk group, this also being associated to maternal drinking during pregnancy. The inference is that in our sample, criminal behavior is more related to complex interactions between environmental and social issues including prenatal alcohol exposure.

Parent-adolescent relationship quality and delay discounting may play important roles in adolescents’ sexual decision making processes, and levels of self-control during adolescence could act as a buffer within these factors. This longitudinal study included 219 adolescent (55% male; mean age = 12.66 years at Wave 1; mean age = 15.10 years at Wave 2) and primary caregiver dyads. Structural equation modeling was utilized to determine whether delay discounting mediated the association between parent-adolescent relationship quality and adolescents’ risky sexual behavior and how this mediated association may differ between those with high versus low self-control. The results revealed parent-adolescent relationship quality plays a role in the development of risky sexual behavior indirectly through levels of delay discounting, but only for adolescents with low self-control. These findings could inform sex education policies and health prevention programs that address adolescent risky sexual behavior. PMID:26202153

Preschoolers observe and imitate the behaviors of those who are similar to them. Therefore, peers may be role models for preschoolers' dietary intake and physical activity in childcare centers. This study examined whether peers' behaviors predict change in preschoolers' dietary intake and physical activity in childcare centers over 9months. A total of 238 preschoolers (3 to 5years old) from 23 childcare centers in two Canadian provinces provided data at the beginning (October 2013 and 2014) and the end (June 2014 and 2015) of a 9-month period for this longitudinal study. Dietary intake was collected at lunch using weighed plate waste and digital photography on two consecutive weekdays. Physical activity was assessed using accelerometers over five days. Multilevel linear regressions were used to estimate the influence of peers' behaviors on preschoolers' change in dietary intake and physical activity over 9months. Results showed that preschoolers whose dietary intake or physical activity level deviated the most from those of their peers at the beginning of the year demonstrated greater change in their intakes and activity levels over 9months, which enabled them to become more similar to their peers (all β 95% CI ranged from -0.835 to -0.074). This study suggests that preschoolers' dietary intake and physical activity may be influenced by the behaviors of their peers in childcare centers. Since peers could play an important role in promoting healthy eating behaviors and physical activity in childcare centers, future studies should test interventions based on positive role modeling by children.

Research on health information has primarily focused on the needs of adults or parents of children with chronic illnesses or consumers. There is limited research on the health information needs of adolescents and in particular those from underserved communities. The primary objective of this qualitative study was to understand the health information needs of healthy, urban adolescents, and how they met those needs. Focus group methodology was used to gather information from a sample of ethnically diverse urban adolescents. Data was analyzed using Kriekelas’ Information Seeking Behavior framework to, examine the participants” report of their immediate and deferred health information needs. Our sample of adolescents used several different sources to satisfy their health information needs depending on acuity and severity, which was congruent with Kriekelas’ framework. Understanding how adolescents use technology to meet their health information needs, and in what order of preference, will be critical for the development of technology that adolescents find useful and has the potential to decrease health disparities.

Importance Parent-adolescent sexual communication has received considerable attention as one factor that can positively impact safer sex among youth; however, the evidence linking communication to youth contraceptive and condom use has not been empirically synthesized. Objective This meta-analysis examined the effect of parent-adolescent sexual communication on youth safer sex behavior and explored potential moderators of this association. Data Sources A systematic search was conducted of studies published through June 2014 using Medline, PsycINFO, and Communication & Mass Media Complete databases and relevant review articles. Study Selection Studies were included if they: 1) sampled adolescents (mean sample age≤18); 2) included an adolescent report of sexual communication with parent(s); 3) measured safer sex behavior; and 4) were published in English. Data Extraction and Synthesis Correlation coefficients (r) and 95% confidence intervals (CIs) were computed from studies and meta-analyzed using random-effects models. Main Outcomes and Measures The primary outcome was safer sex behavior, including use of contraceptives/birth control or condoms. Results Seventy-one independent effects representing over three decades of research on 25,314 adolescents (mean age = 15.1) were synthesized. Across studies, there was a small, significant weighted mean effect (r = .10, [95% CI:0.08–0.13]) linking parent-adolescent sexual communication to safer sex behavior, which was statistically heterogeneous (Q = 203.50, p < .001, I2 = 65.60). Moderation analyses revealed larger effects for communication with girls (r = .12) than boys (r = .04), and among youth who discussed sex with mothers (r = .14) compared to fathers (r = .03). Effects did not differ for contraceptive versus condom use, or among longitudinal versus cross-sectional studies, indicating parent sexual communication had a similar impact across study designs and outcomes. Several methodological issues were identified

Research on parenting practices has focused on individual behaviors while largely failing to consider the context of their use, i.e., general parenting. We examined the extent to which food parenting practices predict children's dietary behavior (classified as unhealthy: snacking, sugar-sweetened beverage; and healthy: water and fruit intake). Furthermore, we tested the moderating role of general parenting on this relationship. Within the KOALA Birth Cohort Study, in the Netherlands, questionnaire data were collected at 6 and 8 years (N = 1654). Correlations were computed to assess the association between food parenting practices and general parenting (i.e., nurturance, behavioral control, structure, coercive control, and overprotection). Linear regression models were fitted to assess whether food parenting practices predict dietary behavior. Instrumental and emotional feeding, and pressure to eat were found to have associations with undesirable child dietary behavior (increased unhealthy intake/decreased healthy intake), whereas associations were in the desirable direction for covert control, encouragement and restriction. Moderation analyses were performed by evaluating interactions with general parenting. The associations of encouragement and covert control with desirable child dietary behaviors were found to be stronger for children who were reared in a positive parenting context. Future research should assess the influence of contextual parenting factors moderating the relationships between food parenting and child dietary behavior as the basis for the development of more effective family-based interventions.

The aim of this study was to identify prevalence and factors associated with violent behavior among adolescents in Aracaju and Metropolitan region. The study included 2207 adolescents (16.03 ± 1.08 years old) enrolled in high schools of the State Public Network. Violent behavior was identified from question 14 of the YRBS-2007 questionnaire with responses categorized as “never” and “one or more times.” Higher prevalence in males in relation to risk factors for adoption of violent behavior was found: cigarette consumption (7.3%), alcohol consumption (39.1%), and marijuana use (3.4%). Data analysis used descriptive statistics and logistic regression with hierarchical model at two levels: (a) sociodemographic variables and (b) behavioral variables. For both sexes, association between violent behavior and cigarette smoking (OR = 3.77, CI 95% = 2.06–6.92 and OR = 1.99, CI 95% = 1.04 to 3.81, male and female, resp.) and alcohol consumption (OR = 3.38, CI 95% = 2.22 to 5.16 and OR = 1.83, CI 95% = 1.28 to 2.63, male and female, resp.) was verified. It was concluded that violent behavior is associated with the consumption of alcoholic beverages and cigarettes among adolescents. PMID:25548796

Among early adolescents (10-14 years), poor diet quality along with physical inactivity can contribute to an increased risk of obesity and associated biomarkers for chronic disease. Approximately one-third of United States (USA) children in this age group are overweight or obese. Therefore, attention to factors affecting dietary intake as one of the primary contributors to obesity is important. Early adolescents consume foods and beverages during eating occasions that occur with and without parental supervision. Parents may influence eating behaviors of early adolescents during eating occasions when they are present or during independent eating occasions by engaging in practices that affect availability of foods and beverages, and through perceived normative beliefs and expectations for intake. Therefore, the purpose of this article was to describe the influence of parenting practices on eating behaviors in general and when specifically applied to independent eating occasions of early adolescents. This information may be helpful to inform parenting interventions targeting obesity prevention among early adolescents focusing on independent eating occasions.

Background and Objective Approximately 20% of US children and adolescents consume pizza on any given day; and pizza intake is associated with higher intakes of energy, sodium, and saturated fat. The reformulation of pizza products has yet to be evaluated as a viable option to improve diets of the US youth. This study modeled the effect on nutrient intakes of two potential pizza reformulation strategies based on the standards established by the Nestlé Nutritional Profiling System (NNPS). Methods Dietary intakes were retrieved from the first 24hr-recall of the National Health and Nutrition Examination Survey (NHANES) 2011–12, for 2655 participants aged 4–19 years. The composition of pizzas in the NHANES food database (n = 69) were compared against the NNPS standards for energy, total fat, saturated fat, sodium, added sugars, and protein. In a reformulation scenario, the nutrient content of pizzas was adjusted to the NNPS standards if these were not met. In a substitution scenario, pizzas that did not meet the standards were replaced by the closest pizza, based on nutrient content, that met all of the NNPS standards. Results Pizzas consistent with all the NNPS standards (29% of all pizzas) were significantly lower in energy, saturated fat and sodium than pizzas that were not. Among pizza consumers, modeled intakes in the reformulation and substitution scenarios were lower in energy (-14 and -45kcal, respectively), saturated fat (-1.2 and -2.7g), and sodium (-143 and -153mg) compared to baseline. Conclusions Potential industry wide reformulation of a single food category or intra-category food substitutions may positively impact dietary intakes of US children and adolescents. Further promotion and support of these complimentary strategies may facilitate the adoption and implementation of reformulation standards. PMID:27706221

This study used data collected from a sample of 840 Italian adolescents (418 boys; M age = 12.58) and their parents (657 mothers; M age = 43.78) to explore the relations between parenting, adolescent self-disclosure, and antisocial behavior. In the hypothesized model, parenting practices (e.g., parental monitoring and control) have direct effects on parental knowledge and antisocial behavior. Parenting style (e.g., parent-child closeness), on the other hand, is directly related to adolescent self-disclosure, which in turn is positively related to parental knowledge and negatively related to adolescents' antisocial behavior. A structural equation model, which incorporated data from parents and adolescents, largely supported the hypothesized model. Gender-specific models also found some gender differences among adolescents and parents, as the hypothesized model adequately fit the subsample of mothers but not fathers. Mothers' closeness to girls predicted their knowledge of their daughters' behavior; mothers' control predicted boys' antisocial behavior.
Adolescents who liked heavy metal music were compared to those who did not on a variety of outcome variables, particularly focusing on reckless behavior. Boys who liked heavy metal music reported a higher rate of a wide range of reckless behavior, including driving behavior, sexual behavior, and drug use. They were also less satisfied with their family relationships. Girls who liked heavy metal music were more reckless in the areas of shoplifting, vandalism, sexual behavior, and drug use, and reported lower self-esteem. Both boys and girls who liked heavy metal music were higher in sensation seeking and more self-assured with regard to sexuality and dating. In regression analyses, the relation between reckless behavior and liking heavy metal music was sustained for five out of twelve variables concerning reckless behavior, including three of four among girls, when sensation seeking and family relationships were entered into the equation before liking or not liking heavy metal music.

The current study used the risk factor approach to test the unique and combined influence of several possible risk factors for cyberbullying attitudes and behavior using a four-wave longitudinal design with an adolescent US sample. Participants (N = 96; average age = 15.50 years) completed measures of cyberbullying attitudes, perceptions of anonymity, cyberbullying behavior, and demographics four times throughout the academic school year. Several logistic regression equations were used to test the contribution of these possible risk factors. Results showed that (a) cyberbullying attitudes and previous cyberbullying behavior were important unique risk factors for later cyberbullying behavior, (b) anonymity and previous cyberbullying behavior were valid risk factors for later cyberbullying attitudes, and (c) the likelihood of engaging in later cyberbullying behavior increased with the addition of risk factors. Overall, results show the unique and combined influence of such risk factors for predicting later cyberbullying behavior. Results are discussed in terms of theory.

Based conceptually on Problem Behavior Theory, Normalization Theory and theories of adolescent ethnic identity formation this study explores relationships between individual and cumulative multiple risk behaviors and suicidal ideation and behavior among mid-adolescents in three different populations in the Middle East. Data from the 2004 Health Behavior in School-Aged Children in the Middle-East (HBSC-ME) study included 8345 10th-grade pupils in three populations: Jewish Israelis (1770), Arab Israelis (2185), and Palestinians in Gaza and the West Bank (4390). We considered risk behaviors and factors including tobacco use, bullying, medically-attended injuries, excessive time with friends, parental disconnectedness, negative school experience, truancy and poor academic performance. Substantial population differences for suicidal tendency and risk behaviors were observed, with notably high levels of suicidal ideation and behavior among Arab-Israeli youth and higher levels of risk behaviors among the Jewish and Arab-Israeli youth. For all populations suicidal tendency was at least 4 times higher among adolescents reporting 4+ risk behaviors, suggesting that similar psychosocial determinants affect patterns of risk behaviors and suicidal tendency. Results highlight the importance of understanding cultural contexts of risk behaviors and suicidal ideation and behavior.

Chronic ethanol intake causes various types of neural damage and behavioral impairments, probably acting through oxidative stress and excitotoxicity, while dietary restriction is considered by some authors to protect the central nervous system from these kinds of damage. In the present study, a factorial experimental design was used to investigate the effects of chronic ethanol and dietary restriction treatments, associated or not, on Wistar rats' exploratory behavior, spatial memory aspects and cortical and hippocampal acetylcholinesterase (AChE) activity. Dietary restriction lasted for the whole experiment, while ethanol treatment lasted for only 3 weeks. Despite the short ethanol treatment duration, for two behavior categories assessed, moving and rearing, an interaction was observed between the effects of chronic ethanol and dietary restriction. There were no significant differences in AChE activities among the groups. Cerebellar neural nitric oxide synthase (nNOs) activity was measured as a first step to assess oxidative stress. Dietary restriction significantly reduced NO formation. The present results indicate that dietary restriction might exert a protective effect against chronic-ethanol-induced changes in exploratory behavior. It is hypothesized that the mechanisms underlying this protection can involve prevention of oxidative stress.

Most health decision-making models posit that deciding to engage in a health behavior involves forming a behavioral intention which then leads to actual behavior. However, behavioral intentions and actual behavior may not be functionally equivalent. Two studies examined whether decision-making factors predicting dietary behaviors were the same as or distinct from those predicting intentions. Actual dietary behavior was proximally predicted by affective associations with the behavior. By contrast, behavioral intentions were predicted by cognitive beliefs about behaviors, with no contribution of affective associations. This dissociation has implications for understanding individual regulation of health behaviors and for behavior change interventions.

Few studies have examined the association between dietary sugar intake and obesity in Asian children and adolescents. We evaluated the association of dietary sugar intake and its food source with obesity in Korean children and adolescents. In this cross-sectional analysis, data were obtained from five studies conducted between 2002 and 2011. The study included 2599 children and adolescents who had completed more than three days of dietary records and had anthropometric data. Total sugar intake was higher in girls than in boys (54.3 g for girls and 46.6 g for boys, p < 0.0001). Sugar intake from milk and fruits was inversely associated with overweight or obesity in girls only (OR for overweight, 0.52; 95% CI, 0.32-0.84; p for trend = 0.0246 and OR for obesity, 0.42; 95% CI, 0.23-0.79; p for trend = 0.0113). Sugar-sweetened beverage (SSB) consumption was not associated with obesity in girls, while boys had lower odds ratios for obesity (OR for obesity, 0.52; 95% CI, 0.26-1.05; p for trend = 0.0310). These results suggest that total sugars and SSB intake in Asian children and adolescents remains relatively low and sugar intake from milk and fruits is associated with a decreased risk of overweight or obesity, especially in girls.

The study included 2599 children and adolescents who had completed more than three days of dietary records and had anthropometric data. Total sugar intake was higher in girls than in boys (54.3 g for girls and 46.6 g for boys, p < 0.0001). Sugar intake from milk and fruits was inversely associated with overweight or obesity in girls only (OR for overweight, 0.52; 95% CI, 0.32–0.84; p for trend = 0.0246 and OR for obesity, 0.42; 95% CI, 0.23–0.79; p for trend = 0.0113). Sugar-sweetened beverage (SSB) consumption was not associated with obesity in girls, while boys had lower odds ratios for obesity (OR for obesity, 0.52; 95% CI, 0.26–1.05; p for trend = 0.0310). These results suggest that total sugars and SSB intake in Asian children and adolescents remains relatively low and sugar intake from milk and fruits is associated with a decreased risk of overweight or obesity, especially in girls.

Purpose American Indian (AI) adolescent girls have higher rates of sexual activity, births and STIs compared to the national average. The purpose of this study was to explore factors that influence urban adolescent AI girls' sexual risk behavior (SRB). Design A qualitative study was conducted using grounded theory methodology to reveal factors and processes that influence SRB. Methods Talking circles, individual interviews, and event history calendars were used with 20 urban AI 15-19 year old girls to explore influences on their sexual behavior. Findings The generated theory, Framing Sexual Risk Behavior, describes both social and structural factors and processes that influenced the girls' sexual behaviors. The theory extends Bronfenbrenner's ecological model by identifying microsystem, mesosystem, and macrosystem influences on sexual behavior, including: Microsystem: Being “Normal,” Native, and Having Goals; Mesosystem: Networks of Family and Friends, Environmental Influences, and Sex Education; and Macrosystem: Tribal Traditions/History and Federal Policy. Discussion Urban AI girls reported similar social and structural influences on SRB as urban adolescents from other racial and ethnic groups. However, differences were noted in the family structure, cultural heritage, and unique history of AIs. Implications for Practice This theory can be used in culturally responsive practice with urban AI girls. PMID:24803532

OBJECTIVE: To analyze the association between weight teasing, body satisfaction and weight control behaviors. METHODS: Cross-sectional study based on adaptation and validity research of a North American questionnaire for adolescent girls about physical activity, nutrition, body image, perceptions, and behaviors. The variables used to conduct the study were weight control behaviors, body satisfaction and presence of teasing by family members. Descriptive analyses were carried out by chi-square test, being significant p<0.05. RESULTS: A total of 159 adolescent girls, with 16.2±1.3 years old were enrolled in this study. Of the total, 60.1% reported that family members did not tease them. The teasing was associated with weight dissatisfaction (p<0.001), body shape (p=0.006), belly (p=0.001), waist (p=0.001), face (p=0.009), arms (p=0.014) and shoulders (p=0.001). As a consequence, there was association with unhealthy weight control behaviors (p<0.001), vomiting (p=0,011), diet (p=0.002) and use of laxatives (p=0.035). CONCLUSIONS: The teasing about body image by family members was associated with risk for unhealthy weight control behaviors in female adolescents. PMID:24473946

The purpose of this study was to elucidate the etiological pathways towards substance use and risky sexual behavior in female adolescent substance abusers. The study had three aims: (1) to determine the relations between behavioral dysregulation, negative affectivity, and childhood victimization with substance use and risky sexual behavior, (2) to determine whether these relations are mediated by internalizing symptomatology, antisocial behavior, and affiliating with an adult boyfriend; and (3) to determine whether age of menarche moderates the relation between the mediating variables and substance use and risky sexual behavior. Multiple behavioral, psychiatric interview, and self-report measures were used to index behavioral dysregulation, negative affectivity, childhood victimization, internalizing symptomatology, antisocial behavior, affiliation with adult boyfriends, substance use, and risky sexual behavior in 125 substance abusing female adolescents and 78 controls between the ages of 14-18 years. Structural equation modeling was used to determine the etiological pathways. Results indicated that behavioral dysregulation, negative affectivity, and childhood victimization were related to substance use and risky sexual behavior. Age of menarche was significantly correlated with affiliation with an older boyfriend and risky sexual behavior. Antisocial behavior mediated the associations between behavioral dysregulation, negative affectivity and childhood victimization with substance use and risky sexual behavior. Affiliation with an adult boyfriend was directly associated with substance use involvement and accounted for the relationship between chronological age and risky sexual behavior. Finally, late menarche enhanced the association between internalizing symptomatology and substance use involvement. The results highlight the importance of behavioral dysregulation, negative affectivity, and childhood victimization in predicting substance use and risky sexual

This cross-sectional study aimed to investigate the nutritional status and dietary intake of HIV-infected children and adolescents and the relationship between nutritional status and dietary intake and CD4(+) T-cell count and viral load. The sample was composed of 49 subjects aged 7-17 years and living in Florianópolis, Brazil. Nutritional status was assessed by height-for-age and body mass index-for-age. Dietary intake was assessed by a food frequency questionnaire. Spearman correlations and multiple linear regressions were used to determine the relationship between energy, nutrient intake and body mass index-for-age and CD4(+) T-cell count and viral load. The mean body mass index-for-age and height-for-age values were -0.26 ± 0.86 and -0.56 ± 0.92, respectively. The energy intake was 50.8% above the estimated energy requirement and inadequate intake of polyunsaturated fat, cholesterol, fibre, calcium and vitamin C was present in 100%, 57.1%, 40.8%, 61.2% and 26.5% of the sample, respectively. Multiple linear regression analyses revealed that energy intake was correlated with CD4+ T-cell count (r = 0.33; p = 0.028) and viral load (r = -0.35; p = 0.019). These data showed low body mass index-for-age and height-for-age z-scores, high energy intake and inadequate intake of important nutrients for immune function, growth and control of chronic diseases. A lower energy intake was correlated with viral suppression and immune preservation.

Since 2003/2004, the United Kingdom has implemented a salt reduction campaign; however, there are no data on salt intake in children as assessed by 24-hour urinary sodium, the gold standard method, to inform this campaign. We performed a cross-sectional study, involving South London school children across 3 age tiers: young children (5- to 6-year olds), intermediate-aged children (8- to 9-year olds), and adolescents (13- to 17-year olds). Dietary salt intake was measured by 24-hour urinary sodium excretion and compared with newly derived maximum salt intake recommendations. In addition, dietary sources of salt were assessed using a 24-hour photographic food diary. Valid urine collections were provided by 340 children (162 girls, 178 boys). The mean salt intakes were 3.75 g/d (95% confidence interval, 3.49-4.01), 4.72 g/d (4.33-5.11), and 7.55 g/d (6.88-8.22) for the 5- to 6-year olds, 8- to 9-year olds, and 13- to 17-year olds, respectively. Sixty-six percent of the 5- to 6-year olds, 73% of the 8- to 9-year olds, and 73% of 13- to 17-year olds had salt intake above their maximum daily intake recommendations. The major sources of dietary salt intake were cereal and cereal-based products (36%, which included bread 15%), meat products (19%), and milk and milk products (11%). This study demonstrates that salt intake in children in South London is high, with most of the salt coming from processed foods. Much further effort is required to reduce the salt content of manufactured foods.

Sprinters are advised to include additional protein sources in their diet. Basal metabolism and vigorous physical activities generate hydrogen ions that need to be buffered. The present follow-up study estimates the dietary potential renal acid load (PRAL) and net endogenous acid production (NEAP) in adolescent sprint athletes. Seven-day food diaries and anthropometrics of 60 adolescent sprint athletes (mean age at start 14.7 ± 1.9 years) were collected every six months over a three year period. Comparisons were made between athletes with a negative (PRAL(-)) versus positive PRAL (PRAL(+)). For the entire sample, mean PRAL values of up to 6 mEq/day were slightly positive despite a relatively high protein intake of around 1.5 g/kg. The NEAP ranging between 42 and 46 mEq/day remained stable during the study period. Athletes with a PRAL(-) (-8 to -10 mEq/day) consumed significantly more fruit and fruit juice than athletes with a PRAL(+) (+9 to 14 mEq/day). Athletes with a PRAL(+) did not consume more meat, fish and poultry than athletes with a PRAL(-). Grains and dairy products were only discriminative between the two groups on one measurement occasion. Lowering the PRAL can be obtained by increasing the consumption of potatoes, fruits, vegetables and vegetable soup.

Nonalcoholic fatty liver disease (NAFLD) is now thought to be the most common liver disease worldwide. Cardiovascular complications are a leading cause of mortality in NAFLD. Fructose, a common nutrient in the westernized diet, has been reported to be associated with increased cardiovascular risk, but its impact on adolescents with NAFLD is not well understood. We designed a 4-week randomized, controlled, double-blinded beverage intervention study. Twenty-four overweight Hispanic-American adolescents who had hepatic fat >8% on imaging and who were regular consumers of sweet beverages were enrolled and randomized to calorie-matched study-provided fructose only or glucose only beverages. After 4 weeks, there was no significant change in hepatic fat or body weight in either group. In the glucose beverage group there was significantly improved adipose insulin sensitivity, high sensitivity C-reactive protein (hs-CRP), and low-density lipoprotein (LDL) oxidation. These findings demonstrate that reduction of fructose improves several important factors related to cardiovascular disease despite a lack of measurable improvement in hepatic steatosis. Reducing dietary fructose may be an effective intervention to blunt atherosclerosis progression among NAFLD patients and should be evaluated in longer term clinical trials. PMID:25111123

The purpose of this study was to estimate the prevalence of suicidal behaviors and their relation to background characteristics, social integration, academic stress, psychological distress, and substance use in a stratified random sample of 9886 high school students in Korea. In a multiple logistic regression, we found that depression was the strongest predictor of suicidal behaviors. The other factors significantly associated with suicidal behaviors were gender, academic stress, hostility and substance use. These results indicate that early identification of risk factors for suicidal behaviors may have potential for reducing possible future suicides.

The goal of the current study was to examine the combined influence of positive reinforcement processes using a behavioral task measuring risk taking propensity (RTP) and negative reinforcement processes using a behavioral task measuring deficits in distress tolerance (DT) on a range of risk taking behaviors among early adolescents. Participants included a community sample of 230 early adolescents (aged 9-13) who completed two behavioral tasks assessing reinforcement processes as well as reported on past year risk behavior involvement as assessed by items from the Youth Risk Behavior Surveillance System at a baseline and a 1-year follow-up assessment. Data indicated that at the Wave 2 assessment, RTP was positively related to number of risk-taking behaviors in the past year but only for those with low DT, with this finding persisting after controlling for the significant influence of male gender and higher sensation seeking. Results of the present study highlight the importance of considering both positive and negative reinforcement processes in combination when investigating vulnerability factors for early risk behavior engagement in youth.

The Dietary Guidelines for Americans is the official nutrition policy statement for the United States. Government involvement in providing information on private behavior, such as food choice, is justified by the high cost of poor diets, as measured in medical expenses and lost productivity. The Guidelines are intended to provide an up-to-date, consistent information base for federal nutrition education and information efforts and food assistance program regulations. Through these policy mechanisms, the Guidelines are assumed to improve dietary behavior, and, ultimately, health. By law, the Dietary Guidelines for Americans must be updated every five years; however, there is no mandate for evaluation. Evaluation could provide useful information to assess the extent to which the Guidelines positively influence health and provide insights into reasons for their successes and limitations. However, evaluation would also present considerable challenges. This paper discusses the critical data and methodological needs for improving evaluation of the Dietary Guidelines for Americans.

Our study aimed to estimate the association between number of siblings and dietary patterns in adolescents. Prospective longitudinal study was developed using data from the birth cohort of the city of Pelotas, Brazil, which included 5249 participants. At the 18-year-old follow-up, from 4563 individuals located, 4106 were interviewed (follow-up rate 81.3%). Of these, 3751 were included in our principal component analysis of dietary patterns. Regular dietary intake of 45 food groups over the previous year was measured with a food frequency questionnaire. We identified four patterns, which accounted for 40% of the total variance in food group consumption. These were labeled “Protein and fast food”, “Fruit and vegetables”, “Common Brazilian”, and “Sweets, soft drinks, and dairy products”. Crude and adjusted analyses of the association between number of siblings and dietary patterns were performed using linear regression. The number of siblings was positively associated with a higher adherence to each dietary pattern, with the exception of the “Common Brazilian” patterns, for which there was no apparent relationship with number of siblings. The findings showed that a greater number of siblings is related to a more diverse diet in the later adolescence, which may predict better nutrient adequacy and health outcomes. PMID:28333975
The primary objective of the present research is to characterize the frequencies of self-injurious behaviors among Turkish adolescents and whether these vary by sex. The sample comprised 371 female and 309 male college students, randomly selected and studying in different colleges in Trabzon (Turkey). The Personal Information Form and the Inventory of Statements About Self-injury were administered. The most pervasive types of self-injurious behaviors reported were "preventing the healing of wounds (peeling the scabs)," "hitting oneself on a tough surface or self-hitting," and "scratching letters, texts, shapes on skin." Sex differences in self-injurious behaviors were observed.

Although adolescents are a group heavily targeted by the e-cigarette industry, research in cue-reactivity has not previously examined adolescents' behavioral and neural responses to e-cigarette advertising. This study addressed this gap through two experiments. In Experiment One, adult traditional cigarette smokers (n = 41) and non-smokers (n = 41) answered questions about e-cigarette and neutral advertising images. The 40 e-cigarette advertising images that most increased desire to use the product were matched to 40 neutral advertising images with similar content. In Experiment Two, the 80 advertising images selected in Experiment One were presented to adolescents (n = 30) during an functional magnetic resonance imaging brain scan. There was a range of traditional cigarette smoking across the sample with some adolescents engaging in daily smoking and others who had never smoked. Adolescents self-reported that viewing the e-cigarette advertising images increased their desire to smoke. Additionally, all participants regardless of smoking statuses showed significantly greater brain activation to e-cigarette advertisements in areas associated with cognitive control (left middle frontal gyrus), reward (right medial frontal gyrus), visual processing/attention (left lingual gyrus/fusiform gyrus, right inferior parietal lobule, left posterior cingulate, left angular gyrus) and memory (right parahippocampus, left insula). Further, an exploratory analysis showed that compared with age-matched non-smokers (n = 7), adolescent smokers (n = 7) displayed significantly greater neural activation to e-cigarette advertising images in the left inferior temporal gyrus/fusiform gyrus, compared with their responses to neutral advertising images. Overall, participants' brain responses to e-cigarette advertisements suggest a need to further investigate the long-run impact of e-cigarette advertising on adolescents.

Recently, the prevalence of post-traumatic stress disorder (PTSD) in adolescence is higher than the prevalence of PTSD in adult populations. PTSD and suicidality are often found in populations of adolescents presenting with other emotional disorders (particularly mood disorders), traumatic grief, childhood abuse, and/or a family or peer history of suicide. The reasons and developments of the association between PTSD and suicidality in adolescence, however, remain unclear. Core psychobiological changes contributing to PTSD affect emotion, arousal, perception of the self and the world, irritability, impulsivity, anger, aggression and depression. There is evidence that the aforementioned factors, as well as alcohol and other drug use may act to moderate the influence of stressful life events and lead to eventual suicidality. Both PTSD and suicidality in adolescents have also been hypothesized to be a result of exposure to violence and negative coping styles. There are many treatment challenges for these populations, yet the most promising prevention and treatments include suicide risk screenings, suicide education, Dialectical Behavioral Therapy, addressing associated coping mechanisms and prescribing anti-depressant and anti-anxiety medications. However, when prescribing medications, physicians do need to be careful to consider the weaknesses and strengths of each of the pharmacological options as they apply to adolescents presenting with PTSD and suicidality.

Although models of exploratory decision making implicate a suite of strategies that guide the pursuit of information, the developmental emergence of these strategies remains poorly understood. This study takes an interdisciplinary perspective, merging computational decision making and developmental approaches to characterize age-related shifts in exploratory strategy from adolescence to young adulthood. Participants were 149 12-28-year-olds who completed a computational explore-exploit paradigm that manipulated reward value, information value, and decision horizon (i.e., the utility that information holds for future choices). Strategic directed exploration, defined as information seeking selective for long time horizons, emerged during adolescence and maintained its level through early adulthood. This age difference was partially driven by adolescents valuing immediate reward over new information. Strategic random exploration, defined as stochastic choice behavior selective for long time horizons, was invoked at comparable levels over the age range, and predicted individual differences in attitudes toward risk taking in daily life within the adolescent portion of the sample. Collectively, these findings reveal an expansion of the diversity of strategic exploration over development, implicate distinct mechanisms for directed and random exploratory strategies, and suggest novel mechanisms for adolescent-typical shifts in decision making.

Impulsivity is a multidimensional construct that has been linked with obesity. To explore profiles of impulsive behavior potentially associated with adolescent weight status, we measured multiple dimensions of impulsivity (delay discounting, sustained attention, and behavioral disinhibition) using laboratory behavioral tasks in a sample of adolescents (N=61). For comparison purposes, we also assessed self-reported impulsive behavior with the BIS-11-A. Participants differed in body mass index: obese (n=21), overweight (n=20), and healthy-weight (n=20). Obese and overweight adolescents were more impulsive on the measure of delay discounting than healthy-weight adolescents, but no difference was found between obese and overweight adolescents on this measure. Obese adolescents also were more impulsive on the measure of inattention compared to overweight and healthy-weight adolescents, who did not differ on this measure. Behavioral disinhibition had no association with weight status, nor did the self-report measure of impulsivity. The additive pattern of these findings for certain laboratory behavioral measures indicates that obese adolescents are more impulsive than their healthy-weight counterparts on two dimensions of behavior, whereas overweight adolescents are more impulsive on only one dimension. Consequently, adolescents who are impulsive on two dimensions of behavior (i.e., delay discounting and sustained attention) may be at greater risk of becoming obese rather than overweight compared to adolescents who are impulsive on only one dimension of behavior (i.e., delay discounting).

Objectives Examine the association between weight loss behaviors and motivations for weight loss in children and adolescents and the association of weight status with these behaviors and motivations in a nationally representative sample. Methods We examined data from the National Health and Nutrition Examination Survey (NHANES), focusing on children in the United States ages 8-15 years, in repeated cross-sections from 2005–2011. Results Half of participants (N=6117) reported attempting to lose weight, and children who were obese attempted to lose weight more frequently (76%) than children who were a healthy weight (15%). Children reported attempting to lose weight by both healthy and unhealthy means: “exercising” (92%), “eating less sweets or fatty foods” (84%), “skipping meals” (35%), and “starving” (18%). The motivation to be better at sports was more likely to be associated with attempting weight loss through healthy behaviors, whereas children motivated by teasing were more likely to engage in unhealthy behaviors. Motivations for losing weight differed by weight status. Conclusions Many children and adolescents attempt to lose weight, using either or both healthy and unhealthy behaviors, and behaviors differed based on motivations for weight loss. Future research should examine how physicians, parents, and teachers can inspire healthy behavior changes. PMID:26718021

Little is known about the stress and coping mechanisms on problem behaviors among Chinese adolescents, which might be quite different from their counterparts in Western cultures. We examined risk process of stress for internalizing outcomes (i.e., psychological distress, self-acceptance) and externalizing outcomes (i.e., substance use, delinquency, violent behavior) among Chinese adolescents. We also examined John Henryism Active Coping as a protective factor in a test of resilience from the negative effects of stress. A cross-sectional survey using self-reported questionnaires was conducted in 2 urban cities in China: Beijing and Xian. Participants included 1,356 students in Grades 7 to 12 (48% male, 52% female). Structural equation modeling analyses were conducted to test the conceptual model. The modifying (protective) effects of John Henryism were tested in multiple-group analysis. After controlling for demographics, we found that stress was associated with decreased self-acceptance and increased psychological distress among adolescents. Higher degree of psychological distress was then associated with increased delinquent behaviors and substance use. The results also indicated that individuals who scored higher in John Henryism reported more substance use as a result of psychological distress. Overall, our results support previous research with Western samples. Although John Henryism did not serve as a protective factor between stress and its negative outcomes, the findings underscore the relevance of addressing stress and possible coping strategies among Chinese adolescents. Further research that refines the active coping tailored for Chinese adolescents is necessary to more precisely test its protective effects.

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

Using a social ecological perspective, we examined the effects of connectedness in multiple domains on health-promoting and health-compromising behaviors among Asian American (AA), Pacific Islander (PI), and Caucasian/White American (WA) adolescents in California. After adjusting for age, gender, and socioeconomic status, the following consistent results emerged across the three ethnic groups: (a) community connectedness increased the odds of physical activity; (b) internal, family, and school connectedness decreased, whereas friend connectedness increased, the odds of substance use; and (c) internal and family connectedness decreased the odds of violent behavior. We also found specific ethnic variations pertaining to the effects of connectedness. Friend connectedness increased the odds of violent behavior for AAs and WAs, but not for PIs. Meanwhile, community connectedness increased the odds of substance use and violent behavior for AAs and PIs, but decreased the odds of these behaviors for WAs. Findings for healthy dietary behavior were inconsistent across ethnic groups and connectedness domains. Our overall findings suggest that the effects of connectedness were more salient for health-compromising behaviors than for health-promoting behaviors. Health prevention and intervention efforts in adolescents could target the role of their connectedness to their multiple social domains.

This study explored the relationships among weight perceptions, dieting behavior, and breakfast eating in 4597 public high school adolescents using the Centers for Disease Control and Prevention Youth Risk Behavior Survey. Adjusted multiple logistic regression models were constructed separately for race and gender groups via SUDAAN (Survey Data Analysis). Adjusted odds ratios [ORs] and 95% confidence intervals were calculated to determine the strength of relationships. Approximately 42% of the sample reported not eating breakfast within the past 5 days, while 41% were trying to lose weight, and 37% were dieting to lose weight. Excessive dietary practices (eg, fasting, taking diet pills or laxatives, and vomiting to lose weight) were reported by approximately 25% of the sample. When compared to those eating breakfast within the past 5 days, all race and gender groups that did not report eating breakfast were significantly more likely to report fasting to lose weight (ORs = 1.70-2.97). In addition, all race/gender groups, with the exception of black females, were significantly more likely to perceive themselves as overweight (ORs = 1.44-1.61) and trying to lose weight (ORs = 1.40-1.72). Among males, not eating breakfast was significantly associated with taking diet pills to lose weight (ORs = 2.31-2.40), eating fewer calories to lose weight (ORs = 1.38-1.49), and inversely associated with trying to gain weight (ORs = 0.71-0.74). Results suggest that these adolescents may be skipping breakfast as part of a patterned lifestyle of unhealthy weight management and that efforts to encourage youth to eat breakfast will likely not ameliorate all dietary challenges that appear beyond the scope of increased breakfast offerings.
Background: Mobile technologies are emerging as a valuable tool to collect and assess dietary intake. Adolescents readily accept and adopt new technologies; hence, a food record application (FRapp) may be used as a tool to promote a better understanding of adolescent’s dietary intake and eating patt...

This study evaluated the Problem Behavior Frequency Scale (PBFS), a self-report measure designed to assess adolescents' frequency of victimization, aggression, and other problem behaviors. Analyses were conducted on a sample of 5,532 adolescents from 37 schools at 4 sites. About half (49%) of participants were male; 48% self-identified as Black non-Hispanic; 21% as Hispanic, 18% as White non-Hispanic. Adolescents completed the PBFS and measures of beliefs and values related to aggression, and delinquent peer associations at the start of the 6th grade and over 2 years later. Ratings of participants' behavior were also obtained from teachers on the Behavioral Assessment System for Children. Confirmatory factor analyses supported a 7-factor model that differentiated among 3 forms of aggression (physical, verbal, and relational), 2 forms of victimization (overt and relational), drug use, and other delinquent behavior. Support was found for strong measurement invariance across gender, sites, and time. The PBFS factors generally showed the expected pattern of correlations with teacher ratings of adolescents' behavior and self-report measures of relevant constructs. (PsycINFO Database Record

Although research supports the influence of parents and peers on adolescent risky behavior, less is known about mechanisms proposed to explain this relation. This study examined the influence of adolescent attitudes and intentions about such behaviors. Prospective, longitudinal data came from rural youth who participated throughout adolescence (n= 451). Observed harsh parenting and relationship with deviant peers was assessed in early adolescence, attitudes and intentions were measured during middle adolescence, and risky behavior was assessed in late adolescence. Results indicated that parenting and deviant peers was related to engagement in tobacco use, alcohol use, and risky sexual behaviors. Moreover, attitudes and intentions mediated this relationship even after parent use and adolescent early involvement in these behaviors were taken into account.

Although substantial research supports the association between parental inconsistent discipline and early adolescent behaviors, less is understood on mechanisms underlying this relation. This study examined the mediating influence of delinquent-oriented attitudes in early adolescence. Using a longitudinal sample of 324 rural adolescents and their parents, findings revealed that inconsistent discipline in 6th grade predicted an increase in adolescent delinquent-oriented attitudes by 7th grade which, in turn, predicted both an increase in early adolescent antisocial behaviors and a decrease in socially competent behaviors by 8th grade. Therefore, it appears that accepting attitudes toward delinquency may in part develop from experiencing inconsistent discipline at home and may offer a possible explanation as to why early adolescents later engage in more antisocial and less socially competent behaviors. Findings may inform family-based preventive intervention programs that seek to decrease behavior problems and promote social competence in early adolescents. PMID:23544924

myfood24 Is an online 24-h dietary assessment tool developed for use among British adolescents and adults. Limited information is available regarding the validity of using new technology in assessing nutritional intake among adolescents. Thus, a relative validation of myfood24 against a face-to-face interviewer-administered 24-h multiple-pass recall (MPR) was conducted among seventy-five British adolescents aged 11-18 years. Participants were asked to complete myfood24 and an interviewer-administered MPR on the same day for 2 non-consecutive days at school. Total energy intake (EI) and nutrients recorded by the two methods were compared using intraclass correlation coefficients (ICC), Bland-Altman plots (using between and within-individual information) and weighted κ to assess the agreement. Energy, macronutrients and other reported nutrients from myfood24 demonstrated strong agreement with the interview MPR data, and ICC ranged from 0·46 for Na to 0·88 for EI. There was no significant bias between the two methods for EI, macronutrients and most reported nutrients. The mean difference between myfood24 and the interviewer-administered MPR for EI was -230 kJ (-55 kcal) (95 % CI -490, 30 kJ (-117, 7 kcal); P=0·4) with limits of agreement ranging between 39 % (3336 kJ (-797 kcal)) lower and 34 % (2874 kJ (687 kcal)) higher than the interviewer-administered MPR. There was good agreement in terms of classifying adolescents into tertiles of EI (κ w =0·64). The agreement between day 1 and day 2 was as good for myfood24 as for the interviewer-administered MPR, reflecting the reliability of myfood24. myfood24 Has the potential to collect dietary data of comparable quality with that of an interviewer-administered MPR.

Summary Objective Evidence suggests that TV viewing is associated with body mass index (BMI) and metabolic syndrome (MetS) in adolescents. However, it is unclear whether dietary intake mediates these relationships. Methods A cross‐sectional analysis was conducted in adolescents (12–19 years) participating in the 2003–2006 United States National Health and Nutrition Examination Survey. BMI z scores (zBMI) (n = 3,161) and MetS (n = 1,379) were calculated using age‐ and sex‐specific criteria for adolescents. TV viewing (h/day) was measured via a self‐reported questionnaire, and dietary intake was assessed using two 24‐h recalls. Using the MacKinnon method, a series of mediation analyses were conducted examining five dietary mediators (total energy intake, fruit and vegetable intake, discretionary snacks, sugar‐sweetened beverages and diet quality) of the relationships between TV viewing and zBMI and MetS. Results Small positive relationships were observed between TV viewing and zBMI (β = 0.99, p < 0.001) and TV viewing and MetS (OR = 1.18, p = 0.046). No dietary element appeared to mediate the relationship between TV viewing and zBMI. However, sugar‐sweetened beverage consumption and fruit and vegetable intake partially mediated the relationship between TV viewing and MetS, explaining 8.7% and 4.1% of the relationship, respectively. Conclusions These findings highlight the complexity of the relationships between TV viewing, dietary intake and cardiometabolic health outcomes, and that TV viewing should remain a target for interventions.

Both the intensity and prevalence of violence and delinquency among children and adolescents have continued to rise during the past fifteen years. Efforts to counteract this development may benefit from recent evidence from developmental psychopathology and neurobiology. A model proposed by Moffitt describes two developmental pathways into antisocial problem behavior: one path characterized by an early onset and a stable course of symptoms ("life-course persistent") and the other by an episodic ("adolescence-limited") occurrence of anti-social behavior. While in the latter the specific developmental tasks and life circumstances of adolescence play a major role in the pathogenesis, persistent antisocial behavior is perceived to be a result of a transactional process between child and environment. Apart from psychosocial factors, biological predispositions (genetic susceptibility) and psychological dispositions (temperament and personality characteristics) are of primary interest. The recent progress in neurobiological and personality research promises significant insights into the underlying pathogenetic mechanisms. Integrating these approaches may help in targeting prevention and early intervention programs to high-risk groups and may thus contribute to improving their effectiveness.

ABSTRACT OBJECTIVE To describe the methodological characteristics of the studies selected and assess variables associated with sedentary behavior in Brazilian children and adolescents. METHODS For this systematic review, we searched four electronic databases: PubMed, Web of Knowledge, LILACS, SciELO. Also, electronic searches were applied in Google Scholar. A supplementary search was conducted in the references lists of the included articles and in non-indexed journals. We included observational studies with children and adolescents aged from three to 19 years developed in Brazil, presenting analyses of associations based on regression methods and published until September 30, 2014. RESULTS Of the 255 potential references retrieved by the searches, 49 met the inclusion criteria and composed the descriptive synthesis. In this set, we identified a great number of cross-sectional studies (n = 43; 88.0%) and high methodological variability on the types of sedentary behavior assessed, measurement tools and cut-off points used. The variables most often associated with sedentary behavior were “high levels of body weight” (in 15 out of 27 studies; 55.0%) and “lower level of physical activity” (in eight out of 16 studies; 50.0%). CONCLUSIONS The findings of this review raise the following demands to the Brazilian agenda of sedentary behavior research geared to children and adolescents: development of longitudinal studies, validation of measuring tools, establishment of risk cut-offs, measurement of sedentary behavior beyond screen time and use of objective measures in addition to questionnaires. In the articles available, the associations between sedentary behavior with “high levels of body weight” and “low levels of physical activity” were observed in different regions of Brazil.

Outside of the family, schools are the most proximal socializing agent available to convey societal norms and prohibitions to young people. In some cases, a positive school experience can compensate for the antisocial influence of family and community. The present study investigated the predictive ability of school-related factors on later deviancy in a random sample of 452 US adolescents 12-18 years of age attending 150 junior or senior high schools in upstate New York and enrolled in a broader prospective study. A measure of conduct problems, obtained 2 years before measurement of school factors, was used to control for the predisposing effects of problematic behavior on later deviance. Academic achievement, academic aspirations, and a learning-focused school environment had deterrent effects on all deviant outcomes assessed--dropping out of school, adolescent pregnancy, engaging in criminal activities, criminal conviction, antisocial personality disorder, and alcohol abuse--independent of age, gender, intelligence quotient, socioeconomic status, childhood conduct problems, and proportion of deviance-oriented friends in adolescence. Given the persistence of deviant behavioral patterns of adolescence into adulthood, the systems-level influences identified in this study should be given careful attention.

This review explains the main effects exerted by sex steroids and other hormones on the adolescent brain. During the transition from puberty to adolescence, these hormones participate in the organizational phenomena that structurally shape some brain circuits. In adulthood, this will propitiate some specific behavior as responses to the hormones now activating those neural circuits. Adolescence is, then, a critical "organizational window" for the brain to develop adequately, since steroid hormones perform important functions at this stage. For this reason, the adolescent years are very important for future behaviors in human beings. Changes that occur or fail to occur during adolescence will determine behaviors for the rest of one's lifetime. Consequently, understanding the link between adolescent behavior and brain development as influenced by sex steroids and other hormones and compounds is very important in order to interpret various psycho-affective pathologies. Lay Summary : The effect of steroid hormones on the development of the adolescent brain, and therefore, on adolescent behavior, is noticeable. This review presents their main activational and organizational effects. During the transition from puberty to adolescence, organizational phenomena triggered by steroids structurally affect the remodeling of brain circuits. Later in adulthood, these changes will be reflected in behavioral responses to such hormones. Adolescence can then be seen as a fundamental "organizational window" during which sex steroids and other hormones and compounds play relevant roles. The understanding of the relationship between adolescent behavior and the way hormones influence brain development help understand some psychological disorders.

Considerable research in the U.S. has established that adolescent antisocial, aggressive, and attention problems have a negative influence on adolescents' ability to become productive members of society. However, although these behaviors appear in other cultures, little is known about the development of these problems among adolescents in countries other than the U.S.. This study contributes to our understanding of personality and parenting factors associated with adolescent problem behaviors using an international sample. Data are from a NIDA-funded study of 884 community-dwelling adolescents in Santiago, Chile (Mean age=14, SD=1.4, 48% females) of mid-to-low socioeconomic status. Results revealed that rule-breaking and aggressive behaviors were both associated with greater levels of adolescent drive but lower levels of parental monitoring and positive parenting by both parents. Adolescents who reported more attention problems were more likely to exhibit driven behavior, more behavioral inhibition, to report lower levels of parental monitoring, and positive parenting by mother and father. Results of interactions revealed that the influences of positive parenting and parental monitoring on adolescent aggressive behaviors varied as a function of the gender of the adolescent. Helping parents build on their parenting skills may result in important reductions in adolescent problem behaviors among U.S. and international adolescents. PMID:23100999

The aim of this research was to assess the effects of fixed orthodontic treatment on dietary intake and behaviour. The study adopted a qualitative approach by conducting semi-structured one-to-one interviews, with 10 adolescent patients (four males; six females) undergoing fixed orthodontic treatment with a mean age of 13.21 (SD 0.71) years. The interviews were transcribed and analysed, by two independent investigators, using framework principles in which emerging themes and ideas were identified. These emerging themes were characterized and compared between patients until no new themes or ideas were identified. Framework analysis identified the following two main themes arising in adolescent patients undergoing fixed orthodontic treatment: pain experience and dietary change. All patients reported varying degrees of pain during the first few days of treatment, after which it was seen to reduce. All patients reported that their diet had changed in response to pain, inability to bite and chew, and in response to dietary instructions given to them by their orthodontist. Patients felt that their eating habits had become healthier during treatment. The study highlights the need to explore dietary changes in a larger population base.

Background Accurately assessing the diets of children and adolescents can be problematic. Use of technologies, such as mobile apps designed to capture food and beverages consumed at eating occasions with images taken using device-embedded cameras, may address many of the barriers to gathering accurate dietary intake data from adolescents. Objective The objectives of this study were to assess the willingness of adolescents to take images of food and beverages at their eating occasions using a novel mobile food record (mFR) and to evaluate the usability of the user confirmation component of the mFR app, referred to as the “review process.” Methods Mixed methods combining quantitative and qualitative protocols were used in this study. Adolescents (11-15-year olds) attending a summer camp were recruited to participate in the study. First, the participants were asked to take images of foods and beverages consumed as meals and snacks for 2 consecutive days using the mFR app running on an iPhone and the number of images taken was noted. This was followed by focus group sessions to evaluate usability, which was analyzed by content and themes. After using the mFR, a think-aloud method was used to evaluate the usability of the mFR method for reviewing system-identified foods (ie, the review process). A usability questionnaire was administered at the end of all activities. Results The mFR was accepted by the majority of the 24 boys and 17 girls (n=41) but varied according to gender and eating occasion. Girls were significantly more likely than boys to capture images of their eating occasions (Fisher exact test, P=.03). Participants were more likely to take images of their breakfasts (90%, 36/40) and lunches (90%, 72/80) and least likely to capture afternoon and evening snacks, 54% (43/80) and 40% (32/80), respectively. The major themes from the focus groups with regard to using the mFR were games, rewards, and the need to know more about why they were using the app

There is limited evidence on the prospective association of time spent in activity intensity (sedentary (SED), moderate (MPA) or vigorous (VPA) physical activity) and dietary intake with adiposity indicators in young people. This study aimed to assess associations between (1) baseline objectively measured activity intensity, dietary energy density (DED) and 4-year change in adiposity and (2) 4-year change in activity intensity/DED and adiposity at follow-up. We conducted cohort analyses including 367 participants (10 years at baseline, 14 years at follow-up) with valid data for objectively measured activity (Actigraph), DED (4-d food diary), anthropometry (waist circumference (WC), %body fat (%BF), fat mass index (FMI), weight status) and covariates. Linear and logistic regression models were fit, including adjustment for DED and moderate-to-vigorous physical activity. Results showed that baseline DED was associated with change in WC (β for 1kJ/g difference: 0·71; 95% CI 0·26, 1·17), particularly in boys (1·26; 95% CI 0·41, 2·16 v. girls: 0·26; 95% CI -0·34, 0·87), but not with %BF, FMI or weight status. In contrast, baseline SED, MPA or VPA were not associated with any of the outcomes. Change in DED was negatively associated with FMI (β for 1kJ/g increase: -0·86; 95% CI -1·59, -0·12) and %BF (-0·86; 95% CI -1·25, -0·11) but not WC (-0·27; 95% CI -1·02, 0·48). Change in SED, MPA and VPA did not predict adiposity at follow-up. In conclusion, activity intensity was not prospectively associated with adiposity, whereas the directions of associations with DED were inconsistent. To inform public health efforts, future studies should continue to analyse longitudinal data to further understand the independent role of different energy-balance behaviours in changes in adiposity in early adolescence.

Collecting accurate and reliable nutritional data from adolescent populations is challenging, with current methods providing significant under-reporting. Therefore, the aim of the study was to determine the accuracy of a combined dietary data collection method (self-reported weighed food diary, supplemented with a 24-h recall) when compared to researcher observed energy intake in male adolescent soccer players. Twelve Academy players from an English Football League club participated in the study. Players attended a 12 h period in the laboratory (08:00 h–20:00 h), during which food and drink items were available and were consumed ad libitum. Food was also provided to consume at home between 20:00 h and 08:00 h the following morning under free-living conditions. To calculate the participant reported energy intake, food and drink items were weighed and recorded in a food diary by each participant, which was supplemented with information provided through a 24-h recall interview the following morning. Linear regression, limits of agreement (LOA) and typical error (coefficient of variation; CV) were used to quantify agreement between observer and participant reported 24-h energy intake. Difference between methods was assessed using a paired samples t-test. Participants systematically under-reported energy intake in comparison to that observed (p < 0.01) but the magnitude of this bias was small and consistent (mean bias = −88 kcal·day−1, 95% CI for bias = −146 to −29 kcal·day−1). For random error, the 95% LOA between methods ranged between −1.11 to 0.37 MJ·day−1 (−256 to 88 kcal·day−1). The standard error of the estimate was low, with a typical error between measurements of 3.1%. These data suggest that the combined dietary data collection method could be used interchangeably with the gold standard observed food intake technique in the population studied providing that appropriate adjustment is made for the systematic under-reporting common to such

Objective Accurate perceptions of weight status are important motivational triggers for weight loss among overweight or obese individuals, yet weight misperception is prevalent. To identify and characterize individuals holding misperceptions around their weight status, it may be informative for clinicians to assess self-reported body mass index (BMI) classification (ie, underweight, normal, overweight, obese) in addition to clinical weight measurement. Methods Self-reported weight classification data from the 2007 Current Visit Information – Child and Adolescent Survey collected at Mayo Clinic in Rochester, MN, were compared with measured clinical height and weight for 2,993 adolescents. Results While, overall, 74.2% of adolescents accurately reported their weight status, females, younger adolescents, and proxy (vs self) reporters were more accurate. Controlling for demographic and behavioral characteristics, the higher an individual’s BMI percentile, the less likely there was agreement between self-report and measured BMI percentile. Those with high BMI who misperceive their weight status were less likely than accurate perceivers to attempt weight loss. Conclusion Adolescents’ and proxies’ misperception of weight status increases with BMI percentile. Obtaining an adolescent’s self-perceived weight status in addition to measured height and weight offers clinicians valuable baseline information to discuss motivation for weight loss. PMID:25525400

Four hundred seventy-nine drug abusing adolescent patients enrolled in seven Straight, Inc. Adolescent Drug-Abuse Treatment Programs in five geographic regions across the United States were studied to determine the severity and patterns of cocaine abuse. Of these, 341 admitted to cocaine use and became part of this survey. Cocaine use was categorized as heavy, intermediate, or light. Areas examined were the addictive spectrum, psychosocial dysfunction, and psychiatric symptoms. Intermediate and heavy users of cocaine abused significantly less marijuana and inhalants than light cocaine abusers. Heavy and intermediate users were more likely to use cocaine intravenously and to use crack. They developed tachyphylaxis more frequently, progressed to weekly use in less than 3 months more frequently, and became preoccupied with obtaining and using cocaine significantly more frequently. They used more sedative hypnotics to calm themselves and engaged in more criminal behavior, such as stealing from parents and stores and passing bad checks. They had more arrests for possession of drugs, stole more cars, sold more drugs, and were more likely to trade sexual favors to obtain the drug. Heavy and intermediate users were significantly more psychiatrically disturbed than light users, becoming more suspicious, nervous, aggressive, and demonstrating increased symptoms of fatigue, sleeplessness, decreased appetite, and increasing cocaine dysphoria. All of these symptoms could be mistaken for psychiatric disorders. This study suggests that cocaine is as addictive in adolescents as in adults; possibly more so. It also causes psychosocial dysfunction and psychiatric symptoms. Further research into cocaine addiction among adolescents is indicated.

The aim of this study was to test whether the associations between adolescent-parent attachment and externalizing problem behavior of adolescents were mediated by adolescent cognitive distortions, self-esteem, parental monitoring and association with deviant peers. A total of 102 adolescents (71 % male; aged 12-19 years) at risk for developing delinquent behaviors reported on attachment, parental monitoring, aggressive and delinquent behavior and peers. Mediation effects were tested by using structural equation modeling. Different pathways were found depending on the type of externalizing behavior. The association between attachment and direct and indirect aggressive behavior was mediated by cognitive distortions. The relation between attachment and delinquency was mediated by deviant peers and parental monitoring. We argue that clinical practice should focus on the attachment relationship between adolescent and parents in order to positively affect risk and protective factors for adolescents' aggressive and delinquent behavior.

This study used data from 5,382 adolescents from the 1997 U.S. National Longitudinal Survey of Youth (NLSY97) to investigate developmental pathways of alcohol use, marijuana use, sexual risk behaviors, and delinquency across ages 14 to 20, examine interrelationships among these risk behaviors across adolescence, and evaluate association between risk behavior trajectories and depressive symptoms in adolescence. Group-based dual trajectory modeling, examining trajectories of two outcomes over time, revealed strong interrelationships among developmental trajectories of the four risk behaviors, and indicated potential pathways to co-occurring risk behaviors. Adolescents with higher levels of alcohol use or marijuana use were more likely to engage in higher levels of early sexual risk-taking and delinquency. Moreover, adolescents involved in higher levels of delinquency were at higher risk for engaging in early sexual risk-taking. Also belonging to the highest risk trajectory of any of the four risk behaviors was positively associated with depressive symptoms in adolescence.

Adolescent sexual behavior is multidimensional, yet most studies of the topic use variable-oriented methods that reduce behaviors to a single dimension. In this study, we used a person-oriented approach to model adolescent sexual behavior comprehensively, using data from the National Longitudinal Study of Adolescent Health. We identified five latent classes of adolescent sexual behavior: Abstinent (39%), Oral Sex (10%), Low-Risk (25%), Multi-Partner Normative (12%), and Multi-Partner Early (13%). Membership in riskier classes of sexual behavior was predicted by substance use and depressive symptoms. Class membership was also associated with young adult STI outcomes although these associations differed by gender. Male adolescents' STI rates increased with membership in classes with more risky behaviors whereas females' rates were consistent among all sexually active classes. These findings demonstrate the advantages of examining adolescent sexuality in a way that emphasizes its complexity.

Antisocial behavior is strongly associated with academic failure in adolescence. There is a solid body of evidence that points to parenting style as one of its main predictors. The objective of this work is to elaborate a reduced, valid, and reliable version of the questionnaire by Oliva et al. (2007) to evaluate the dimensions of parenting style and to analyze its psychometric properties in a sample of Spanish adolescents. To that end, the designed questionnaire was applied to 1974 adolescents 12-18 years of age from Asturias (Spain). Regarding construct validity, the results show that the model that best represents the data is composed of six dimensions of parenting style, just as in the original scale, namely affection and communication; promotion of autonomy; behavioral control; psychological control; self-disclosure; and humor. The psychological control factor negatively correlates with the other factors, with the exception of behavioral control, with which it positively correlates. The remaining correlations among the factors in the parenting style questionnaire are positive. Regarding internal consistency, the reliability analysis for each factor supports the suitability of this six-factor model. With regard to criterion validity, as expected based on the evidence available, the six dimensions of parenting style correlate in a statistically significant manner with the three antisocial behavior measures used as criteria (off-line school aggression, antisocial behavior, and antisocial friendships). Specifically, all dimensions negatively correlate with the three variables, except for psychological control. In the latter case, the correlation is positive. The theoretical and practical implications of these results are discussed.

Research over the past 20 years suggests that the quality of the parent-adolescent relationship significantly affects the development of risk behaviors in adolescent health. The purpose of this paper is to present a review of studies published between 1996-2007 that address specific relationships between parenting styles and six priority adolescent risk behaviors. The review supports the substantial influence of parenting style on adolescent development. Adolescents raised in authoritative households consistently demonstrate higher protective and fewer risk behaviors than adolescents from non-authoritative families. There is also considerable evidence to show that parenting styles and behaviors related to warmth, communication and disciplinary practices predict important mediators, including academic achievement and psychosocial adjustment. Careful examination of parenting style patterns in diverse populations, particularly with respect to physical activity and unintentional injury, will be a critical next step in the development of efficacious, culturally tailored adolescent health promotion interventions.

Dietary fatty acids (FA) play a role in several (patho)physiological processes at any age, and different FA have different effects on lipid status and health outcome. The present study aims to describe the FA intake and its main food sources in a population of healthy European adolescents and to assess the variation in intake as a function of non-dietary factors. FA intake was assessed with 24 h recall interviews in 1804 adolescents aged 12·5-17·5 years. Usual intakes were calculated using the multiple source method. Multilevel analyses, adjusting for study centre, were used to investigate the influence of non-dietary factors. The mean total fat intake was 33·3 (sd 1·2) % of total energy intake (%E). The mean SFA intake was 13·8 (sd 1·2) %E, with 99·8 % of the population exceeding the recommendations. SFA was mainly delivered by meat and cake, pies and biscuits. In most adolescents, the PUFA intake was too low, and 35·5 % of the population did not achieve the minimum recommended intake for α-linolenic acid (ALA). The main determinants of FA intake in the present study population were age and sex, as well as physical activity in the male subgroup. No contributions of body composition, socio-economic status or sexual maturation to the variance in FA intake were observed. In conclusion, the most important public health concerns regarding FA intake in this adolescent population were the low intake of ALA and the high intake of SFA, mainly seen in the younger-aged boys. In this group the major contributor to SFA was meat.

Adolescents and young adults are the fastest-growing age group of people living with HIVinfection in the United States. Yet many adolescents and young adults with high-risk behaviors for HIV are unaware of their HIV status and have never had an HIV test. The purpose of our work was to understand minority adolescents’ beliefs, attitudes, and behaviors related to HIV testing. We conducted focus group sessions with 41 minority adolescents to assess their perceptions about HIV testing. We triangulated the findings from our focus group data with data from a 125-question survey. Analysis of focus group data demonstrated that Perceived Susceptibility, Perceived Severity, Perceived Benefits, Perceived Barriers, and Cues to Action influenced adolescents’ decisions to get tested for HIV. Findings support the need to design interventions that address adolescents’ perceived barriers to HIV testing and increase access to and knowledge about HIV testing. PMID:25283353

We examined the relations among parenting behaviors, adolescents' self-esteem, and neighborhood risk with a Midwestern sample of 324 Latino adolescents. The findings suggest that boys' self-esteem is influenced by both mothers' and fathers' parenting behaviors, whereas girls' self-esteem is influenced by mothers' behaviors only. In addition, the…
Background Associations between food choice and body composition in previous studies of adolescents have been inconsistent. This may be due to the body composition measures used, or these associations may be affected by the dieting status of adolescents. The objective of this study was to investigate the association between dietary patterns and body composition in adolescents, and determine if these associations are moderated by dieting status. Methods Information on food consumption and current dieting status was collected, using a web-based survey, in 681 adolescents (mean age 15.8 (SD 0.9) years) from schools in Otago, New Zealand. Non-dieters were defined as those reporting not being on a diet as they were “happy with their weight”. Principal components analysis (PCA) was used to determine dietary patterns. Body mass index (BMI), waist circumference (WC), waist-to-height ratio (WHtR), fat mass index (FMI), and fat-free mass index (FFMI) were examined as outcomes. Generalized estimating equations were used to examine associations between dietary patterns and body composition. Results PCA produced three dietary patterns: ‘Treat Foods’, ‘Fruits and Vegetables’, and ‘Basic Foods’. A standard deviation increase in ‘Basic Foods’ was associated with a 3.58% decrease in FMI (95%CI −6.14, -0.94) in the total sample. When separate sex analysis was undertaken significant negative associations were found in boys only, between the ‘Basic Food’ score and WC, WHtR, FMI, and FFMI, while the ‘Fruits and Vegetables’ pattern was negatively associated with FMI. Associations between ‘Treat Foods’ and BMI, WC, and WHtR in non-dieters were positive, while these associations were negative for all other participants. Conclusions Significant associations were found between dietary patterns and indices of both central and total adiposity, but not BMI. Therefore using only BMI measures may not be useful in this age group. Since our results were

This study examines the validity of a Spanish-language dietary behaviors self-report questionnaire (LDBQ) for Latinos with diabetes. The sample (n = 252) was Spanish-speaking, female (77%), middle-aged (mean age = 55 years), low-education (56% < 8th grade education), and low-income (50% < $10,000 annual household income). Baseline and 12-month measures were collected as part of a randomized clinical trial. LDBQ reliability, validity, and sensitivity to change over time were evaluated using exploratory factor analysis; internal consistency analysis; and correlation analysis using baseline and change scores for: LDBQ, three day 24-hour dietary recall nutrient mean, and clinical measures. Cronbach’s alphas were moderate. Four factors were identified at both time points. Significant baseline correlations (r) were found for LDBQ total scores, factor scores and: caloric intake (r = −.29 to −.34); total dietary fiber (r = .19); sodium (r = −.24 to −.30); percent calories from total fat (r = −.16); fat subtypes (r = −.16 to .15); and percent calories from protein (r = .17). Twelvemonth data produced a similar pattern. T-tests of LDBQ change scores showed significantly greater change in dietary behaviors for the intervention group than for the control group, t(135) = −4.17, p < .01. LDBQ change scores correlated significantly with mean 24-hour nutrient intake and a subset of clinical measures, but were not associated with clinical change scores (except HDL). The LDBQ is a useful tool to assess and target behaviors for change and assess intervention effects. PMID:21443994

Parent-adolescent relationship quality and delay discounting may play important roles in adolescents' sexual decision making processes, and levels of self-control during adolescence could act as a buffer within these factors. This longitudinal study included 219 adolescent (55 % male; mean age = 12.66 years at Wave 1; mean age = 15.10 years at Wave 2) and primary caregiver dyads. Structural equation modeling (SEM) was utilized to determine whether delay discounting mediated the association between parent-adolescent relationship quality and adolescents' risky sexual behavior and how this mediated association may differ between those with high versus low self-control. The results revealed parent-adolescent relationship quality plays a role in the development of risky sexual behavior indirectly through levels of delay discounting, but only for adolescents with low self-control. These findings could inform sex education policies and health prevention programs that address adolescent risky sexual behavior.

The aim of this study was to examine insomnia symptoms, behavioral problems, and suicidality among adolescents of insomniac parents (IP) and non-insomniac parents (NIP). A family survey of sleep and health was conducted among 1090 adolescents and their parents in Jinan, China. Adolescents completed a sleep and health questionnaire to report their sleep and mental health problems. Parents reported their insomnia symptoms and history of mental disorders. Insomnia, behavioral problems, and suicidal behavior were compared between IP adolescents and NIP adolescents. IP adolescents were more likely than NIP adolescents to report insomnia symptoms, use of sleep medication, suicidal ideation, suicide plan, and suicide attempt. IP adolescents scored significantly higher than NIP adolescents on withdrawn and externalizing behavioral problems. After adjustment for demographics and behavioral problems, parental insomnia remained to be significantly associated with adolescent suicidal ideation and suicide plan. Our findings support the need for early screening and formal assessment of sleep and mental health in adolescents of insomniac parents.

Investigation of the role of adolescents' patterns of close relationships with significant adults may be of particular interest in populations with learning disabilities ("LD") during adolescence, because attachment relationship variables may act as risk or protective factors during this developmental period when trajectories are set that can lead to difficulties in adulthood. Specifically, this study examined a model of protective factors comprising patterns of close relationships between adolescents (n=369; 53 % female; aged 15-17) and significant adults (mother, father, homeroom teacher) for explaining adolescents' socioemotional and behavioral adjustment, comparing adolescents with and without LD. The current assessment of adolescents' socioemotional adjustment included both internalizing aspects (loneliness, affect, and internalizing behavior syndrome) and externalizing aspects (externalizing behavior syndrome). On most measures, significant group differences emerged between adolescents with LD (n=181) and adolescents with typical development (n=188). SEM analysis found high fit between the theoretical model and empirical findings. Both groups showed similar paths between adolescent-mother attachment and adolescent adjustment, whereas significant group differences emerged for the contribution of adolescents' close relationships with fathers and teachers to adolescents' adjustment. The discussion focuses on the possible unique value of close relationships with each attachment figure at home and at school for adolescents with LD versus typical development.

Adolescence is a period marked by important physical and social changes that can lead to a negative body image. The purpose of this study was to find a model enabling the appearance of behavioral impairment related to body image (restrictions, avoidance, and checking) to be predicted by body image attitudes (concern or Appearance Orientation, and dissatisfaction or Appearance Evaluation), Gender, emotional symptomatology, self-consciousness, ideas of reference (IR) and age. A total of 661 participants (67.47% girls) with an average age of 17.14 years (SD=2.34) filled in the GHQ-28, SCS on self-consciousness, REF referential thinking scale, MBSRQ (AO and AE), and BIAQ. A partial mediation model was found for IR, age and depressive symptomatology between dissatisfaction and concern about body image and Gender, to behavioral impairment related to body image. The results found suggest that age, depressive symptomatology, and IR may be mediator variables in the relationship between dissatisfaction and concern about body image, on body image behavioral impairment. This relationship implies a severity to be considered in intervention and monitoring of body image behavioral impairments in adolescents.

In this essay, we focus on empathy in children and adolescents with disruptive behavior disorders (DBD), based on the assumption that lack of empathy is a risk factor for the development of DBD. We reflect on the heterogeneity of DBD, the complex nature of the empathy construct, discuss empathy's role in aggression, and review recent findings from studies on empathic skills in children and adolescents with DBD. Research suggests that the mechanisms underlying empathy problems may be different for DBD subtypes. Individuals with psychopathic tendencies may show a selective impairment in empathy with sadness and fear due to abnormalities in neural circuits connected with the amygdala. Individuals without these tendencies may show little empathy for a variety of reasons, such as hostile attributions, anxiety and/or poor regulatory skills. Understanding more about the nature and causes of empathy dysfunction in DBD could aid in identifying subtypes and help to improve prevention and intervention programs. Suggestions for future research are made.

The goal of this study was to examine whether moral affect, moral cognition, negative emotionality, and attribution biases independently predicted adolescents' prosocial and aggressive behavior in adolescence. A total of 148 adolescents completed self-report measures of prosocial and aggressive behavior, moral affect, moral cognition, negative emotionality, and attribution biases. Although in general all 3 factors (emotional, moral, and social cognitive) were correlated with adolescent social behavior, the most consistent independent predictors of adolescent social behavior were moral affect and cognition. These findings have important implications for intervention and suggest that programs that promote adolescent perspective taking, moral reasoning, and moral affect are needed to reduce aggressive behavior and promote prosocial behavior.

A relation between pica (the craving and purposive consumption of nonfood items) during pregnancy and anemia is observed frequently. However, few studies related pica behaviors to biomarkers of iron status, and little is known about pica prevalence in U.S. pregnant adolescents. To address this, we undertook a longitudinal study examining iron status and pica behaviors among a group of 158 pregnant adolescents (aged ≤18 y). Approximately two-thirds of the participants were African American and 25% were Hispanic. Maternal iron status indicators [hemoglobin, soluble transferrin receptor, serum ferritin (SF), total body iron (TBI), and serum hepcidin] were assessed during pregnancy (18.5-37.3 wk) and at delivery. Pica behavior was assessed up to 3 times across gestation. Among the 158 adolescents, 46% reported engaging in pica behavior. Substances ingested included ice (37%), starches (8%), powders (4%), and soap (3%). During pregnancy, mean SF [geometric mean: 13.6 μg/L (95% CI: 11.0, 17.0 μg/L)], TBI (mean ± SD: 2.5 ± 4.2 mg/kg), and hepcidin [geometric mean: 19.1 μg/L (95% CI: 16.3, 22.2 μg/L)] concentrations were significantly lower (P < 0.05) in the pica group (n = 72) than values observed among the non-pica group [SF, geometric mean: 21.1 μg/L (95% CI: 18.0, 25.0 μg/L); TBI, mean ± SD: 4.3 ± 3.5 mg/kg; hepcidin, geometric mean: 27.1 μg/L (95%: 23.1, 32.1 μg/L); n = 86]. Although additional studies must address the etiology of these relations, this practice should be screened for, given its association with low iron status and because many of the substances ingested may be harmful. This trial was registered at clinicaltrials.gov as NCT01019902.

Resistant starch (RS) is a dietary fiber that exerts multiple beneficial effects. The current study explored the effects of dietary RS on selected brain and behavioral functions in adult and aged rodents. Because glucokinase (GK) expression in hypothalamic arcuate nucleus and area postrema of the brainstem is important for brain glucose sensing, GK mRNA was measured by brain nuclei microdissection and PCR. Adult RS-fed rats had a higher GK mRNA than controls in both brain nuclei, an indicator of improved brain glucose sensing. Next, we tested whether dietary RS improve selected behaviors in aged mice. RS-fed aged mice exhibited (i) an increased eating responses to fasting, a behavioral indicator of improvement in aged brain glucose sensing; (ii) a longer latency to fall from an accelerating rotarod, a behavioral indicator of improved motor coordination; and (iii) a higher serum active glucagon-like peptide-1 (GLP-1). Then, GLP-1 receptor null (GLP-1RKO) mice were used to test the role of GLP-1 in brain glucose sensing, and they exhibited impaired eating responses to fasting. We conclude that in rodents (i) dietary RS improves two important indicators of brain function: glucose sensing and motor coordination, and (ii) GLP-1 is important in the optimal feeding response to a fast.

Background The stability of dietary habits through various life-stages is not well understood. A better understanding of the tracking of diet over time could have implications for health promotion as well as for the planning of nutritional epidemiology studies. We examined the stability of dietary intakes of children and adolescents over six years. Methods As part of the European Youth Heart Study, in 1998-9, a 24-h dietary recall was performed on over one thousand 9- and 15-year-olds in Sweden. In 2004-5, 40% returned to the follow-up study. These 452 subjects (273 15- and 179 21-year-olds) were assigned to age- and gender-specific tertiles of intakes of food groups, energy, selected nutrients and energy density (low, mid and high) at each time point. The agreement between the classification of subjects into tertiles at both time points was examined using Cohen's weighted κ and other stability coefficients. We included a dropout analysis and considered the effect that energy mis-reporting might have on our results. Results Fair tracking was seen between childhood and adolescence for the milk, fil and yoghurt food group (κ = 0.30), and between adolescence and young adulthood for fruit (κ = 0.24). Slight tracking was observed for most other food groups and fair to slight tracking for all nutrients studied. Only membership of the high milk, fil and yoghurt tertile could be predicted from membership at baseline, in children. Excluding potential energy mis-reporters did not affect the results. Conclusions Despite the long time between data collections, and the method of dietary data collection used, evidence for slight tracking was observed for most food groups and nutrients over these six years.

The purpose of this study was to examine the sociocultural factors related to weight behaviors in African American adolescents utilizing a social ecological approach. A descriptive correlational design included a sample of 145 African American adolescents. Perceived familial socialization, ethnic identity, physical activity, and eating behavior patterns were measured. Data were analyzed using descriptive statistics, Pearson product-moment correlations, and multiple regression equations. Perceived maternal socialization was significantly related to adolescent eating behaviors and physical activity whereas perceived paternal socialization was significantly related only to their physical activity. The adolescents' ethnic identity was not significantly related to their eating behaviors or physical activity. Health care providers who work with adolescents and their families can use the initial findings from this study to encourage healthy weight-related behaviors while reducing the obesity epidemic within the African American adolescent population in a developmentally appropriate and culturally sensitive manner.

Adolescents have high rates of sexually transmitted infections (STIs). Adolescents consuming alcohol and using drugs have markedly greater HIV/STI risk and are a priority population for intervention. Accurate measurement of sexual risk behavior is critical for understanding individual's risk for HIV/STI, transmission dynamics of HIV/STI, and evaluating the efficacy of interventions designed reduce HIV/STI risk. However, significant challenges to accurately measuring adolescents' self-reported sexual behavior are well-documented. Recent advances in microbiology, such as the use of less invasive specimen collection for DNA assays, can assist researchers in more accurately measuring adolescents' sexual risk behavior. However, the majority of studies of adolescents' sexual risk rely solely on self-reported behavior; therefore, methods to improve the validity of adolescents' self-reported sexual behavior are needed. In addition, integrating biologic measures to complement self-reported measures are recommended, when appropriate and feasible.

The aim of this cross-sectional study was to use social cognitive theory to predict overweight and obesity behaviors in adolescent girls in Iran. Valid and reliable questionnaires about nutritional and physical activity regarding social cognitive theory constructs (self-efficacy, social support, outcome expectations, and outcome expectancies), dietary habits, and physical activity were filled by 172 overweight and obese girl adolescents. The mean age and body mass index were 13.4 ± 0.6 years and 28.2 ± 3.6 kg/m(2), respectively. Body mass index was significantly related to hours of television viewing (p = .003) and grams of junk food (p = .001). None of the social cognitive theory constructs were found to be significant predictors for servings of fruits and vegetables, grams of junk foods, minutes of physical activity, and hours of sedentary behaviors. In future, more culturally appropriate models need to be developed in Iran that can explain and predict prevention behaviors of obesity in Iranian adolescents.

Background It has long been theorized that a relatively robust dietary intake impacts cognitive function. The aim of the study was to explore dietary intake and cognitive function in healthy Korean children and adolescents. Methods Three hundred and seventeen healthy children with no previous diagnosis of neurologic or psychiatric disorders were evaluated (167 girls and 150 boys with a mean age of 11.8 ± 3.3 years). Analysis indicators including food frequency questionnaires (FFQs) consisting of 76 items and neurocognitive tests including symbol digit modalities (SDMT), verbal memory, visual memory, shift attention, reasoning, and digit span (forward and backward) tests were observed and recorded. Results The standard deviation in reaction time was significantly shorter in girls than in boys (p < 0.05). Verbal memory and SDMT percentile results were significantly higher in girls than in boys (p < 0.05). Vitamin C and potassium intake showed positive correlation with SDMT results (p < 0.05). Vitamin B1 intake showed positive correlation with the results of digit span forward tasks and SDMT (p < 0.01). Vitamin B6 intake showed positive correlation with the results of digit span forward tasks (p < 0.01). The consumption of noodles showed negative correlation with verbal memory, SDMT, shift attention, and reasoning test results (p < 0.05). The consumption of fast food showed negative correlation with SDMT and reasoning test results (p < 0.05). The consumption of Coca-Cola showed negative correlation with the results of verbal memory tests (p < 0.05). The consumption of mushrooms showed positive correlation with visual memory and reasoning test results (p < 0.05). The consumption of nuts showed positive correlation with SDMT results (p < 0.01). Omission errors were negatively correlated with the intake of protein, vitamin B1, vitamin B2, niacin, and vitamin B6 (p < 0.05), as well as with vitamin D and zinc intake (p < 0.01). Reaction time showed positive correlation

1. The author used a survey tool to measure attitudes of individuals toward health and social factors specific to a low fat/low cholesterol diet. 2. Participants attending the cholesterol screening were healthy and already motivated to be aware of their cholesterol counts. The percent of diet pattern change was not influenced by knowledge of either a low, borderline, or high cholesterol level. 3. Although further testing of this instrument is needed, raw individual scores seem to indicate that motivated screening participants feel a diet low in fat and cholesterol has positive health implications and is not a social inconvenience. 4. There was no significant difference between the traditional and goal setting teaching methods in teaching hospital employee cholesterol screening participants to reduce dietary fat intake.

This study examined the associations between adolescent self-report of aggression and adolescents' perceptions of parenting practices in a sample of African American early adolescents living in low-income, urban communities. Sixth graders (N = 209) completed questionnaires about their aggressive behaviors and perceptions of caregivers' parenting practices at two time points during the school year. Path model findings reveal that adolescent-reported aggression at Time 1 predicted higher levels of perceived parent psychological control and perceived parent expectations for aggressive solutions to conflicts at Time 2. Findings suggest that early adolescent aggression elicits negative parenting behaviors at a subsequent time point.

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.

Internalizing symptoms such as withdrawn and anxious-depressed behavior are common in adolescence. This prospective longitudinal study helps to gain insight into the development of internalizing behavior, focusing on the role of early parent-child interaction while ruling out genetic similarity as a confounder. More specifically, the central question addressed in this study was whether parental sensitivity and child inhibited temperament predict children's withdrawn and anxious-depressed behavior in middle childhood and adolescence. We followed 160 early-adopted children (53 % girls) from infancy to adolescence. Structural equation modeling was used to test relationships both prospectively and concurrently. The results revealed that more sensitive parenting in infancy and middle childhood predicted less inhibited behavior in adolescence, which in turn predicted fewer internalizing problems in adolescence. The findings suggest that maternal sensitivity lowers adolescents' inhibited behavior and decreases the risk for adolescents' internalizing problem behavior indirectly through lower levels of inhibition. Supporting sensitive parenting in the years before adolescence may protect children from developing inhibited behavior and internalizing behavior problems in adolescence.

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.

This study examined whether different types of media affect the use of dietary proteins and amino acid supplements, and intent to use anabolic-androgenic steroids. A random sample of 618 boys aged 11-18 years from eight schools in the Flemish part of Belgium completed standardized questionnaires as part of the Media and Adolescent Health Study. The survey measured exposure to sports media, appearance-focused media, fitness media, use of dietary supplements, and intent to use anabolic-androgenic steroids. Data were analyzed using logistic regressions and are presented as adjusted odds ratios (OR) and 95 % confidence intervals (CI); 8.6 % indicated to have used dietary proteins, 3.9 % indicated to have used amino acid supplements, and 11.8 % would consider using anabolic-androgenic steroids. After adjusting for fitness activity, exposure to fitness media was associated with the use of dietary proteins (OR = 7.24, CI = 2.25-23.28) and amino acid supplements (5.16, 1.21-21.92; 44.30, 8.25-238). Intent to use anabolic-androgenic steroids was associated with exposure to fitness media (2.38, 1.08-5.26; 8.07, 2.55-25.53) and appearance-focused media (6.02, 1.40-25.82; 8.94, 1.78-44.98). Sports media did not correlate with the use of dietary supplements and intent to use anabolic-androgenic steroids. Specific types of media are strong predictors of the use of supplements in adolescent boys. This provides an opportunity for intervention and prevention through the selection of fitness media as a communication channel. Health practitioners should also be aware that the contemporary body culture exerts pressure not only on girls but also on boys.

We conducted second nationwide survey on smoking behavior among Japanese high school students. The survey was a cross-sectional sampling survey. The survey's targets were junior and senior high schools throughout Japan. Sample schools were selected by stratified cluster sampling. Self-administered anonymous questionnaires were sent to sample schools for all students to fill out. 65.6% of the junior high schools and 67.0% of the senior high schools were responded to this survey. A total of 117,325 students responded and 115,814 questionnaires were subjected to analysis. 7.5% of boys and 3.8% of girls in the 1st grade of junior high school were classified as current smokers, compared with 36.9% of boys and 15.6% of girls in 3rd grade of senior high school. Less than 1% of boys and girls in the 1st grade of junior high school were classified as daily smokers, this figure increased markedly by the 3rd grade of senior high school to reach 25.4% of boys and 7.1% of girls. Of students in the 3rd grade of senior high school, 21.2% of boys and 9.9% of girls had tried smoking before 13 year of age. Cigarette consumption also increased with age, although the proportion of those smoking 20 or more cigarettes per day did not. The major source for cigarettes among current smokers was vending machines. This survey revealed that smoking prevalence among Japanese high school students has already reached quite high level. Comprehensive energetic measures for control minor smoking are necessary in Japan.

Girls who experience earlier pubertal timing relative to peers also exhibit earlier timing of sexual intercourse and more unstable sexual relationships. Although pubertal development initiates feelings of physical desire, the transition into romantic and sexual relationships involves complex biological and social processes contributing both to physical maturation and to individual interpretations of pubertal experiences. Using a sample of female sibling pairs (n = 923 pairs) from the National Longitudinal Study of Adolescent Health, the present study investigated associations among menarche and perceived pubertal timing, age of first sexual intercourse (AFI), and adolescent dating and sexual behavior using a behavioral genetic approach. Genetic factors influencing age at menarche and perceived pubertal timing predicted AFI through shared genetic pathways, whereas genetic factors related only to perceived pubertal timing predicted engagement in dating, romantic sex, and nonromantic sex in the previous 18 months. These results suggest that a girl's interpretation of her pubertal timing beyond objective timing is important to consider for the timing and the contexts of romantic and reproductive behavior.

Objective Joint use policies (JUP) encourage shared facility use, usually between schools and a city or private organization, for both physical activity-related and non-physical activity-related programs. Little is known about JUP’s impact on physical activity (PA). This study examined whether more specific JUPs were associated with increased PA and decreased sedentary behavior (SB) in adolescents. Methods Data on PA, sports participation, and SB were taken from annual cross-sectional nationally representative samples of 51,269 8th, 10th and 12th grade public school students nested in 461 school districts in the US from 2009–2011. JUP measures were constructed using information obtained from corresponding school district JU policies. Multivariable analyses were conducted, controlling for individual demographic and socioeconomic characteristics and clustering at the district level. Results Results showed small associations between more specific JUPs and increased PA (IRR 1.01, 95% CI: 1.00, 1.02). Closer examination of specific JUP provisions indicates that specifying what times facilities are available for use was associated with vigorous exercise and prioritizing school or affiliated organizations’ use and which spaces were available for use were associated with vigorous exercise and more frequent PA participation, which includes participation in sports or athletics. No associations were found between more specific JUPs and SB. Conclusions JUPS may have small influences on adolescent physical activity behavior. Future longitudinal studies should be conducted to examine the impact of JUPs in conjunction with other physical activity-related policies and environmental changes to determine what impact they have on overall adolescent physical activity and sedentary behavior.

There is little research on how specific parent-adolescent sexual communication topics influence Latino/a youth's sexual behaviors, and how gender and generational status may moderate effects. This study examined effects of three different messages on intercourse and condom use among 1944 Latino/as from the National Longitudinal Study of Adolescent Health (T1 mean age=15.46; sd=1.50). Results indicated discussing health consequences predicted higher odds of intercourse one year later across gender and generation groups. Birth control recommendation effects on subsequent intercourse and condom use differed by generational status and gender. Results indicated that message content is important for understanding effects of parent-adolescent sex communication on adolescents' behavior, and underscored the need to consider gender and generational status in Latino/a parent-adolescent sexual communication studies.

Adolescence is characterized by drastic behavioral adaptations and comprises a particularly vulnerable period for the emergence of various psychiatric disorders. Growing evidence reveals that the pathophysiology of these disorders might derive from aberrations of normal neurodevelopmental changes in the adolescent brain. Understanding the molecular underpinnings of adolescent behavior is therefore critical for understanding the origin of psychopathology, but the molecular mechanisms that trigger adolescent behavior are unknown. Here, we hypothesize that the cannabinoid type-1 receptor (CB1R) may play a critical role in mediating adolescent behavior because enhanced endocannabinoid (eCB) signaling has been suggested to occur transiently during adolescence. To study enhanced CB1R signaling, we introduced a missense mutation (F238L) into the rat Cnr1 gene that encodes for the CB1R. According to our hypothesis, rats with the F238L mutation (Cnr1F238L) should sustain features of adolescent behavior into adulthood. Gain of function of the mutated receptor was demonstrated by in silico modeling and was verified functionally in a series of biochemical and electrophysiological experiments. Mutant rats exhibit an adolescent-like phenotype during adulthood compared with wild-type littermates, with typical high risk/novelty seeking, increased peer interaction, enhanced impulsivity, and augmented reward sensitivity for drug and nondrug reward. Partial inhibition of CB1R activity in Cnr1F238L mutant rats normalized behavior and led to a wild-type phenotype. We conclude that the activity state and functionality of the CB1R is critical for mediating adolescent behavior. These findings implicate the eCB system as an important research target for the neuropathology of adolescent-onset mental health disorders. SIGNIFICANCE STATEMENT We present the first rodent model with a gain-of-function mutation in the cannabinoid type-1 receptor (CB1R). Adult mutant rats exhibit an adolescent

The Eastern Mediterranean region is characterized by one of the highest burdens of paediatric obesity worldwide. This study aims at examining dietary, lifestyle, and socio-economic correlates of overweight, obesity, and abdominal adiposity amongst children and adolescents in Lebanon, a country of the Eastern Mediterranean basin. A nationally representative cross-sectional survey was conducted on 6-19-year-old subjects (n = 868). Socio-demographic, lifestyle, dietary, and anthropometric data (weight, height, waist circumference) were collected. Overweight and obesity were defined based on BMI z-scores. Elevated waist circumference (WC) and elevated waist to height ratio (WHtR) were used as indices of abdominal obesity. Of the study sample, 34.8% were overweight, 13.2% were obese, 14.0% had elevated WC, and 21.3% had elevated WHtR. Multivariate logistic regression analyses showed that male gender, maternal employment, residence in the capital Beirut, sedentarity, and higher consumption of fast food and sugar sweetened beverages were associated with increased risk of obesity, overweight, and abdominal adiposity, while regular breakfast consumption, higher intakes of milk/dairies and added fats/oils were amongst the factors associated with decreased risk. The study's findings call for culture-specific intervention strategies for the promotion of physical activity, healthy lifestyle, and dietary practices amongst Lebanese children and adolescents.

Throughout the past several decades, studies have uncovered a wealth of information about the neural circuitry underlying fear learning and extinction that has helped to inform treatments for fear-related disorders such as post-traumatic stress and anxiety. Yet, up to 40 percent of people do not respond to such treatments. Adolescence, in particular, is a developmental stage during which anxiety disorders peak, yet little is known about the development of fear-related neural circuitry during this period. Moreover, pharmacological and behavioral therapies that have been developed are based on mature circuitry and function. Here, we review neural circuitry implicated in fear learning and data from adolescent mouse and human fear learning studies. In addition, we propose a developmental model of fear neural circuitry that may optimize current treatments and inform when, during development, specific treatments for anxiety may be most effective.

Research on the role of sex-related Internet use in adolescents' sexual development has often isolated the Internet and online behaviors from other, offline influencing factors in adolescents' lives, such as processes in the peer domain. The aim of this study was to test an integrative model explaining how receptive (i.e., use of sexually explicit Internet material [SEIM]) and interactive (i.e., use of social networking sites [SNS]) sex-related online behaviors interrelate with perceived peer norms in predicting adolescents' experience with sexual behavior. Structural equation modeling on longitudinal data from 1,132 Dutch adolescents (M(age) T1 = 13.95; range 11-17; 52.7% boys) demonstrated concurrent, direct, and indirect effects between sex-related online behaviors, perceived peer norms, and experience with sexual behavior. SEIM use (among boys) and SNS use (among boys and girls) predicted increases in adolescents' perceptions of peer approval of sexual behavior and/or in their estimates of the numbers of sexually active peers. These perceptions, in turn, predicted increases in adolescents' level of experience with sexual behavior at the end of the study. Boys' SNS use also directly predicted increased levels of experience with sexual behavior. These findings highlight the need for multisystemic research and intervention development to promote adolescents' sexual health.

Primates deal with fluctuations of the thermal environment by both physiological and behavioral mechanisms of thermoregulation. In this article we focus on non-hibernating lemurs, which are hypometabolic and have to cope with a seasonal environment. Behavioral thermoregulation has received little attention compared with specific physiological adaptations to seasonality, i.e., hibernation and torpor, which characterize a number of lemurs. We investigated the role of seasonality and dietary-related factors in determining frequencies of resting, social and postural thermoregulation, and microhabitat selection in collared lemurs, Eulemur collaris. We observed two groups of collared lemurs over a 14-month period in the littoral forest of Sainte Luce, Southern Madagascar. Frequencies of total resting and time spent in huddling, prone, and curled postures were collected via 5-min instantaneous sampling. Microhabitat selection was evaluated as the proportion of time spent in the upper canopy as compared with other layers. Climatic variables were recorded by automatic data loggers, while dietary variables were derived from phenological data and nutritional analyses of the ingested food items. We weighted the combined effects of climatic and dietary variables on the different types of behavioral thermoregulation by means of canonical correlation analysis. The model with the strongest canonical correlation included a first root representing mainly feeding time, day length, and ambient temperature and a second root representing diet quality and height of feeding trees. The output indicated that collared lemurs adapt to thermal and dietary-related metabolic stress by adjusting resting time, social, and postural thermoregulation.

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 The purpose of this study was to determine the effect of stress reduction via the Transcendental Meditation program on school rule infractions in adolescents. Methods Forty-five African American adolescents (ages 15–18 years) with high normal systolic blood pressure were randomly assigned to either Transcendental Meditation (n = 25) or health education control (n = 20) groups. The meditation group engaged in 15-min sessions at home and at school each day for 4 months. The control group was presented 15-min sessions of health education at school each day for 4 months. Primary outcome measures were changes in absenteeism, school rule infractions and suspension days during the four-month pretest period prior to randomization compared with the four-month intervention period. Results Comparing the pretest and intervention periods, the meditation group exhibited a mean decrease of 6.4 absentee periods compared to an increase of 4.8 in the control group (p < .05). The meditation group exhibited a mean decrease of 0.1 infractions over the four months compared to an increase of 0.3 in the control group (p < .03). There was a mean reduction of 0.3 suspension days due to behavior-related problems in the meditation group compared to an increase of 1.2 in the control group (p < .04). Conclusion These findings demonstrate that the Transcendental Meditation program conducted in the school setting has a beneficial impact upon absenteeism, rule infractions, and suspension rates in African American adolescents.

275 adolescents aged 10-19 receiving attention at the infantojuvenile department of pregnancy interruption and of sexually transmitted infections of "Ramón Gonzalez Coro" and "Eusebio Hernández" Gynecoobstetric Teaching Hospitals, both in Havana City, were studied from August, 1999, to September, 2000, aimed at knowing the behavior of the infection caused by Trichomonas vaginalis in this population group. The results yielded 18.1 % of positivity to parasitosis. It was proved by the calculation of relative risk that the adolescents that had an active or past infection due to Trichomonas vaginalis have more possibilities of getting an infection produced by human Papilomavirus than those without this condition. It was demonstrated that 78 (28.3 %) of the total of patients examined had some type of lesion in the uterine cervix. Some risk factors as non using condon, having multiple sexual partners and the early beginning of sexual relations, which may facilitate the adquisition of this parasitosis in a population so vulnerable as the adolescents, were made known.

Objective: To evaluate the inappropriate eating behaviors (IEB) of female adolescents over a one-year period. Methods: 290 adolescents aged between 11 and 14 years old participated in the three research stages (T1: first four months, T2: second four months and T3: third four months). The Eating Attitudes Test (EAT-26) was applied to assess the IEB. Weight and height were measured to calculate body mass index (BMI) in the three study periods. Analysis of variance for repeated measures was used to analyze the data, adjusted for the scores of the Body Shape Questionnaire and the Brazil Economic Classification Criteria. Results: Girls at T1 showed a higher frequency of IEB compared to T2 (p=0.001) and T3 (p=0.001). The findings also indicated higher values for BMI in T3 in relation to T1 (p=0.04). The other comparisons did not show statistically significant differences. Conclusions: IEB scores of female adolescents declined over one year. PMID:24676195

The disruptive behavior disorders are among the most prevalent youth psychiatric disorders, and they predict numerous problematic outcomes in adulthood. This study examined multiple domains of risk during early childhood and early adolescence as longitudinal predictors of disruptive behavior disorder diagnoses among adolescent males. Early adolescent risks in the domains of sociodemographic factors, the caregiving context, and youth attributes were examined as mediators of associations between early childhood risks and disruptive behavior disorder diagnoses. Participants were 309 males from a longitudinal study of low-income mothers and their sons. Caregiving and youth risk during early adolescence each predicted the likelihood of receiving a disruptive behavior disorder diagnosis. Furthermore, sociodemographic and caregiving risk during early childhood were indirectly associated with disruptive behavior disorder diagnoses via their association with early adolescent risk. The findings suggest that preventive interventions targeting risk across domains may reduce the prevalence of disruptive behavior disorders.

This study investigates parenting practices and the reported sexual and delinquent behaviors among Thai adolescents, by focusing on the difference between sons and daughters. Data were derived from 420 families whose adolescents aged 13–14 were randomly selected from seven districts in Bangkok using the probability proportional to size (PPS) method. Interviews were conducted with one parent and one adolescent. Female adolescents reported higher levels of parental monitoring, parental rules, communication about sex and parental disapproval of sex, as compared to males. There were no gender differences in the reported sexual and delinquent behaviors among the adolescents. For males, high levels of parental monitoring, greater perception of parent disapproval of sex, and being raised by authoritative parents were associated with less delinquent behaviors. Among females, parental monitoring and parental closeness served as protective factors against sexual and delinquent behaviors. These findings should be useful for developing a body of knowledge and understanding on adolescent rearing among Thai parents. PMID:20420103

Caffeine is the psychostimulant most consumed worldwide but concerns arise about the growing intake of caffeine-containing drinks by adolescents since the effects of caffeine on cognitive functions and neurochemical aspects of late brain maturation during adolescence are poorly known. We now studied the behavioral impact in adolescent male rats of regular caffeine intake at low (0.1mg/mL), moderate (0.3mg/mL) and moderate/high (1.0mg/mL) doses only during their active period (from 7:00 P.M. to 7:00 A.M.). All tested doses of caffeine were devoid of effects on locomotor activity, but triggered anxiogenic effects. Caffeine (0.3 and 1mg/mL) improved the performance in the object recognition task, but the higher dose of caffeine (1.0mg/mL) decreased the habituation to an open-field arena, suggesting impaired non-associative memory. All tested doses of caffeine decreased the density of glial fibrillary acidic protein and synaptosomal-associated protein-25, but failed to modify neuron-specific nuclear protein immunoreactivity in the hippocampus and cerebral cortex. Caffeine (0.3-1mg/mL) increased the density of brain-derived neurotrophic factor (BDNF) and proBDNF density as well as adenosine A1 receptor density in the hippocampus, whereas the higher dose of caffeine (1mg/mL) increased the density of proBDNF and BDNF and decreased A1 receptor density in the cerebral cortex. These findings document an impact of caffeine consumption in adolescent rats with a dual impact on anxiety and recognition memory, associated with changes in BDNF levels and decreases of astrocytic and nerve terminal markers without overt neuronal damage in hippocampal and cortical regions.

Purpose The purpose of this study was to identify the ways in which urban Jamaican mothers influence their adolescent daughters’ sexual beliefs and behaviors in order to incorporate them into the design of a family-based human immunodeficiency virus (HIV) risk reduction intervention program. Design Focus groups were conducted with 46 14- to 18-year-old adolescent girls and 30 mothers or female guardians of adolescent girls recruited from community-based organizations in and around Kingston and St. Andrew, Jamaica. Separate focus groups were held with mothers and daughters; each included 6 to 10 participants. Focus group sessions were scripted, led by teams that included trained Jamaican and American facilitators and note-takers, and audio-taped to ensure data accuracy. Data were analyzed using qualitative content analysis. Findings Four major maternal influences were identified: mother-daughter relationship quality, mother-daughter sexual communication, monitoring or supervision, and maternal sexual role modeling. Mothers’ and daughters’ reports were consistent; both groups identified positive and negative influences within each category. Conclusions Some maternal influences were positive and health promoting; others were negative and promoted unsafe sexual activity and risk for HIV and other sexually transmitted infections. These influences were incorporated into the design of a culture-specific family-based HIV risk reduction intervention tailored to the needs of urban Jamaican adolescent girls and their mothers. Clinical Relevance In order to be effective, family-based HIV risk reduction interventions should be theory based and tailored to the target audience. The four maternal influences identified in this formative study were incorporated into the subsequent intervention design. PMID:22339731

Published research demonstrates an association between exposure to media sexual content and a variety of sex-related outcomes for adolescents. What is not known is the mechanism through which sexual content produces this "media effect" on adolescent beliefs, attitudes, and behavior. Using the Integrative Model of Behavioral Prediction, this…

Adolescence is a tumultuous and challenging time period in life. Sexual risk behavior among adolescents is a widespread topic of interest in the current literature. Two common factors that influence increased sexual risk behavior are symptoms of depression and negative body image. The purpose of this study was to investigate the effect of body image and symptoms of depression upon sexual risk-taking in an adolescent female population. A secondary data analysis of the 2011 Youth Risk Behavior Survey (YRBS) was used to explore girls' sexual activity, body image, and mental health. There were 7,708 high-school girls who participated in this study. Three questions were used to represent the constructs under investigation. There were significant correlations between sexual activity, body image, and symptoms of depression; only symptoms of depression were significant predictors of both sexual activity and condom usage. Body image was a predictor of sexual activity, but not condom use. Our findings support previous studies that suggested that people with depressive symptoms were more likely to engage in risky sexual behaviors. Our study also supports the idea that a negative body image decreases sexual activity; however, other researchers have reported that negative body image leads to an increase in sexual activity.

In the family-based prevention science literature, family functioning, defined as positive parenting, parental involvement, family cohesion, family communication, parental monitoring of peers, and parent–adolescent communication, has been shown to ameliorate HIV risk behaviors in Hispanic youth. However, the majority of studies have relied solely on parent or adolescent reports and we know very little about parent–adolescent family functioning discrepancies. Therefore, the purpose of this study was to examine whether and to what extent parent–adolescent discrepancies in family functioning increased the risk of HIV risk behaviors, including substance use and sexual risk behaviors, and whether these associations vary as a function of acculturation and youth gender. A total of 746 Hispanic 8th grade youth and their primary caregivers were included in the study. Structural equation modeling findings indicate that parent–adolescent family functioning discrepancies are associated with an increased risk of Hispanic adolescent HIV risk behaviors, including lifetime and past 90-day alcohol and illicit drug use, and early sex initiation. In addition, study findings indicate that results vary by acculturation and youth gender. Findings are discussed in the context of existing family-based research and practice in preventing and reducing HIV risk behaviors among Hispanic youth and their families. PMID:24617745

The purpose of this study was to explore clinical changes observed in suicidal adolescents treated with an adapted form of Dialectical Behavior Therapy for adolescents (A-DBT-A) in a tertiary care setting. We conducted an open-label naturalistic study including 61 adolescents with self-injurious thoughts and behaviors and associated features of borderline personality disorder, who underwent a 15-week course of A-DBT-A. Pre- and post-treatment measures were administered, the primary outcome being the total score on the Suicidal Ideas Questionnaire. Self-harm, symptoms of borderline personality disorder, resiliency measures, predictors of response, and predictors of attrition were also explored. Among participants who completed post-treatment measures, we found a significant reduction in suicidal ideation (n = 31, p < 0.001). Secondary outcomes also suggested improvement. Baseline substance use predicted attrition (HR 2.51; 95% CI 1.03-6.14; p < 0.05), as did baseline impulsivity score on the Life Problems Inventory (HR 1.03; 95% CI 1.004-1.06; p < 0.05). Overall, we observed clinical improvements in adolescents receiving A-DBT-A.

Despite accumulated experimental evidence of the negative effects of exposure to media-idealized images, the degree to which body image, and eating related disturbances are caused by media portrayals of gendered beauty ideals remains controversial. On the basis of the most up-to-date meta-analysis of experimental studies indicating that media-idealized images have the most harmful and substantial impact on vulnerable individuals regardless of gender (i.e., "internalizers" and "self-objectifiers"), the current longitudinal study examined the direct and mediated links posited in objectification theory among media-ideal internalization, self-objectification, shame and anxiety surrounding the body and appearance, dietary restraint, and binge eating. Data collected from 685 adolescents aged between 14 and 15 at baseline (47 % males), who were interviewed and completed standardized measures annually over a 3-year period, were analyzed using a structural equation modeling approach. Results indicated that media-ideal internalization predicted later thinking and scrutinizing of one's body from an external observer's standpoint (or self-objectification), which then predicted later negative emotional experiences related to one's body and appearance. In turn, these negative emotional experiences predicted subsequent dietary restraint and binge eating, and each of these core features of eating disorders influenced each other. Differences in the strength of these associations across gender were not observed, and all indirect effects were significant. The study provides valuable information about how the cultural values embodied by gendered beauty ideals negatively influence adolescents' feelings, thoughts and behaviors regarding their own body, and on the complex processes involved in disordered eating. Practical implications are discussed.

Prior research on the association of mental health and behavior problems with academic achievement is limited because it does not consider multiple problems simultaneously, take co-occurring problems into account, and control for academic aptitude. We addressed these limitations using data from the National Longitudinal Study of Adolescent Health (N = 6,315). We estimated the associations of depression, attention problems, delinquency, and substance use with two indicators of academic achievement (high school GPA and highest degree received) with controls for academic aptitude. Attention problems, delinquency, and substance use were significantly associated with diminished achievement, but depression was not. Combinations of problems involving substance use were especially consequential. Our results demonstrate that the social consequences of mental health problems are not the inevitable result of diminished functional ability but, rather, reflect negative social responses. These results also encourage a broader perspective on mental health by demonstrating that behavior problems heighten the negative consequences of more traditional forms of distress.

Early initiation of sexual intercourse has been associated with negative consequences, such as higher rates of unwanted pregnancy and HIV infection. This study examined the attitudes and behavior of rural Thai adolescent students aged 16 to 20 years from northern Thailand regarding sexual intercourse. Differences between participants who previously had sexual intercourse and those who had not were explored. Those who had not previously had sexual intercourse were asked about the reasons why they had not had sex, their future plans for having sex and their dating experiences. More than 70% of participants stated they had not previously had sexual intercourse but one third of this group reported engaging in other sexual behavior. There were significant differences by gender, religion, ethnicity, and household income between those who had previously had sex and those who had not. Among those who had not previously had sexual intercourse, concern for their parents' feelings was the most common reason for delaying intercourse. About two-thirds of this group had plans not to have sexual intercourse until after marriage; nearly half of them reported currently having a boyfriend/girlfriend. Interventions aimed at delaying sexual intercourse should involve adolescents in their design and include their attitudes for delaying intercourse. Because of many gender differences seen in our study, interventions should be designed differently for males and females in rural northern Thailand.

Objective: To study the prevalence of suicidal behavior and its epidemiological correlates amongst adolescent students in south Delhi. Settings and Design: A cross-sectional study in three schools and two colleges in south Delhi. Participants: A total of 550 adolescent students aged 14 to 19 years selected by cluster sampling. Statistical Analysis: Proportions, chi square test, bivariate logistic regression. Results: About 15.8% reported having thought of attempting suicide, while 28 (5.1%) had actually attempted suicide, both being more in females than in males. Statistically significant associations were observed with the age of the student, living status of parents, working status of mother, and whether the student was working part-time. The two variables found significant on multivariate analysis were female gender and the number of role models the student had ever seen smoking or drinking. Conclusion: The prevalence of suicide-risk behavior was found to be quite high and is a matter that should evoke public health concern. PMID:19771304

This study examined neural correlates of empathy in adolescence while observing harmful acts. A total of 32 participants (aged 12-19 years) viewed pictures depicting negative (offenders inflicting intentional harm) and positive (friends socializing) social situations. After viewing each picture, participants could allocate hypothetical points to either the offender or the victim in a dictator game. Behaviorally, participants of all ages acted prosocially towards victims, fairly towards positive individuals and punishingly towards offenders. Brain imaging analyses showed that viewing negative situations was associated with more activation in the bilateral intraparietal lobule and the superior temporal sulcus (STS), whereas viewing positive situations was associated with more medial prefrontal cortex and left temporal parietal junction activity. Analyses testing for associations between brain activity and self-reported empathy showed that the STS was correlated negatively with reports of understanding others' distress and the willingness to help others. Together, the findings suggest that adolescents show similar prosocial behavior, as previously reported in adults with greater STS activity, when observing negative social acts that is modulated by an individual's empathy for others.

This study examined associations among early adolescent romantic relationships, peer standing, problem behaviors, and gender as a moderator of these associations, in a sample of 320 seventh-grade students. Popular and controversial status youth were more likely to have a romantic partner, whereas neglected status youth were less likely to have a romantic partner. Similarly, youth perceived as conventional and unconventional leaders were also more likely to have a romantic partner than were non-leaders. Youth who had a romantic partner drank more alcohol and were more aggressive than were youth who did not have a romantic partner. Among those youth who had romantic partners, those who reported having more deviance-prone partners were themselves more likely to use alcohol and to be more aggressive, and those who engaged in deviant behavior with their partners used more alcohol. However, these associations varied somewhat by gender. These findings underscore the salience of early romantic partner relationships in the adjustment of early adolescents.

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.

Gambling, and gambling related problems, are recognized as an emerging health issue among adolescents. Adolescent gambling is associated with numerous individual, social, and family characteristics. This paper provides a review of 21 empirical studies published between 1997 and 2008 that examine family influences on adolescent gambling behavior. Family influences on gambling behavior are conceptualized in the following five domains: (1) family sociodemographic factors, (2) general family climate, (3) family members' attitudes and behaviors, (4) parenting practices, and (5) family relationship characteristics. Based on the review of extant literature, there is empirical evidence that family characteristics are associated with adolescent gambling and further examination of family system influences on gambling behavior is needed. Gaps in the current literature and recommendations for future research are discussed to help inform the study of family influences on adolescent gambling behavior.

Purpose Adolescent problem behaviors (substance use, delinquency, school dropout, pregnancy, and violence) are costly not only for individuals, but for entire communities. Policymakers and practitioners that are interested in preventing these problem behaviors are faced with many programming options. In this review, we discuss two criteria for selecting relevant parenting programs, and provide five examples of such programs. Design/methodology/approach The first criterion for program selection is theory based. Well-supported theories, such as the social development model, have laid out key family-based risk and protective factors for problem behavior. Programs that target these risk and protective factors are more likely to be effective. Second, programs should have demonstrated efficacy; these interventions have been called “evidence-based programs” (EBP). This review highlights the importance of evidence from rigorous research designs, such as randomized clinical trials, in order to establish program efficacy. Findings Nurse-Family Partnership, The Incredible Years, Positive Parenting Program, Strengthening Families 10–14, and Staying Connected with Your Teen are examined. The unique features of each program are briefly presented. Evidence showing impact on family risk and protective factors, as well as long-term problem behaviors, is reviewed. Finally, a measure of cost effectiveness of each program is provided. Originality/value We propose that not all programs are of equal value, and suggest two simple criteria for selecting a parenting program with a high likelihood for positive outcomes. Furthermore, although this review is not exhaustive, the five examples of EBPs offer a good start for policymakers and practitioners seeking to implement effective programs in their communities. Thus, this paper offers practical suggestions for those grappling with investments in child and adolescent programs on the ground. PMID:24416068

Interpersonal dynamics within friendships were observed in a sample of 120 (60 male, 60 female) ethnically diverse 16- and 17-year-old adolescents characterized as persistently antisocial, adolescent-onset, and normative. Dyadic mutuality and deviant talk were coded from videotaped friendship interactions. Persistently antisocial adolescents demonstrated lower levels of dyadic mutuality compared with adolescent-onset and normative adolescents. Persistently antisocial and adolescent-onset adolescents spent more time in deviant talk than did normative adolescents. Across groups, girls were rated as more mutual and coded less in deviant talk than boys. Furthermore, friendship dyads who engaged in high levels of deviant talk and were mutual in their interactions reported the highest rates of antisocial behavior.
