Adolescence represents a pivotal stage in the development of positive or negative body image. Many influences exist during the teen years including transitions (eg, puberty) that affect one's body shape, weight status, and appearance. Weight status exists along a spectrum between being obese (ie, where one's body weight is in the 95th percentile for age and gender) to being underweight. Salient influences on body image include the media, which can target adolescents, and peers who help shape beliefs about the perceived body ideal. Internalization of and pressures to conform to these socially prescribed body ideals help to explain associations between weight status and body image. The concepts of fat talk and weight-related bullying during adolescence greatly contribute to an overemphasis on body weight and appearance as well as the development of negative body perceptions and dissatisfaction surrounding specific body parts. This article provides an overview of the significance of adolescent development in shaping body image, the relationship between body image and adolescent weight status, and the consequences of having a negative body image during adolescence (ie, disordered eating, eating disorders, and dysfunctional exercise). Practical implications for promoting a healthy weight status and positive body image among adolescents will be discussed.

The prevalence of overweight and obesity among adolescents is rising rapidly in many countries, including Malaysia. This article aims to present the associations between body mass index-based body weight status, body weight perception, and weight control practices among adolescents in Malaysia. The Malaysia School Based Nutrition Survey 2012, which included a body weight perception questionnaire and anthropometric measurements, was conducted on a representative sample of 40 011 students from Standard 4 until Form 5, with a 90.5% response rate. Comparing actual and perceived body weight status, the findings show that 13.8% of adolescents underestimated their weight, 35.0% overestimated, and 51.2% correctly judged their own weight. Significantly more normal weight girls felt they were overweight, whereas significantly more overweight boys perceived themselves as underweight. The overall appropriateness of weight control practices to body weight was 72.6%. Adolescents attempting to lose or gain weight need to have better understanding toward desirable behavioral changes. © 2014 APJPH.
Full Text Available Objective: An investigation of the interplay between various types of adolescents’ perceptions of weight status in predicting adolescents’ nutrition behavior and their body weight was conducted. In particular, it was hypothesized that the relationship between parental and peers’ perceptions of their own weight status (reported by adolescents and objectively measured weight status of adolescents would be mediated by three types of adolescents’ weight status perceptions (adolescents’ own weight perceptions, parental perceptions of adolescents’ weight status perceived by participants, and peers’ perceptions of adolescents’ weight status perceived by participants and by adolescents’ nutrition behaviors. Design: Data were collected twice, with a 13-month follow-up. Participants (N = 1096 were aged 14-20, with BMI ranging from 16.20 to 41.21. Multiple mediation analysis with two sequential mediators was applied.Main outcome measures: At the baseline adolescents completed the questionnaire assessing their nutrition behaviors and weight status perceptions. Weight and height were measured objectively at baseline and follow-up.Results: Two types of weight perceptions (adolescents’ own weight status perceptions, peers’ perceptions of adolescents’ weight status reported by participants, and adolescents’ nutrition behaviors mediated the relationship between the others’ own weight perceptions and adolescents’ weight status. No indirect effects of others’ own weight perceptions on adolescents’ weight status through parental perceptions were found.Conclusion: Adolescents’ nutrition behaviors and body weight status depend on what they think about their own weight status and what they think of their peers’ perceptions, but do not depend on what adolescents think of their parents’ perceptions.

There is a wide continuum of conditioned pain modulation (CPM) in adults with older adults experiencing an attenuated CPM response compared with younger adults. Less is known for adolescents and the role of anthropometrics. Fifty-six adolescents (15.1 ± 1.8 years; 32 normal weight and 24 overweight/obese; 27 boys) completed in a CPM session that included anthropometric testing. Pressure pain thresholds were measured at the nailbed and deltoid muscle (test stimuli) with the foot submerged in a cool or ice water bath (conditioning stimulus). Weight status, body composition (Dual-energy X-ray absorptiometry scan), physical activity levels and clinical pain were also evaluated. The CPM response in adolescents was similar across sites (nailbed vs. deltoid), weight status (normal vs. overweight/obese) and sex. CPM measured at the deltoid muscle was positively associated with left arm lean mass but not fat mass; lean mass of the arm uniquely predicted 10% of the CPM magnitude. CPM measured at the nailbed was positively correlated with physical activity levels. These results suggest that lean mass and physical activity levels may contribute to endogenous pain inhibition in adolescents across weight status. © 2016 European Pain Federation - EFIC®
Full Text Available Depressive symptoms in adolescence have been a subject of considerable controversy in terms of their nature, severity and identification. The aim of the study was to investigate the possible association between weight status and depressive symptoms among 18 year-old Greek adolescents. A cross-sectional study design was used. The study population consisted of 200 students of the University of Athens who fulfilled the following criteria: age 18 years, absence of clinical depression, no history of hospitalization in a mental institution, no history of alcohol abuse. Weight status was assessed by Body Mass Index (BMI (kg/m2 and calculated from weight and height measurements. Severity of depressive symptoms was assessed by Centre for Epidemiologic Studies-Depression Scale (CES-D. In univariate analysis, CES-D score was significantly associated with adolescents’ gender and BMI. The multivariate analysis showed that CES-D score was negatively related to BMI even after controlling the confounding effect of gender (P=0.018, B=-0.378. Depressive symptoms are related to weight status of adolescents.

The current study aimed to determine gender differences in nutritional habits, eating behaviour, weight status, body image and weight control practices during early and late adolescence. 677 Viennese pupils (253 boys and 424 girls) between the ages 10 and 18 years (x = 14.1 yrs; +/- 2.2) were enrolled in the study. Weight status was determined by means of body mass index percentiles. To assess eating behavior, food preferences, body image and weight control practices, a 48 item questionnaire was developed. Significant gender differences in weight status were observable during late adolescence only. Girls are significantly less satisfied with their body weight. Furthermore, girls practice dieting and weight control to avoid any weight gain more frequently than boys. Gender differences in eating behavior intensified from early to late adolescence. From early to late adolescence, meal size decreased among girls, while it remains stabile or increased among boys. Boys eat generally more than girls. Furthermore, boys preferred meat and fast food while girls consumed fruits, vegetables and healthy food significantly more frequently. These gender differences are explained by gender specific energetic demands and culture typical beauty ideals.

Abstract Background Body weight is highly associated with overall health status. Being severely thin or obese may impose the risk of many health problems. Early detection of body mass index (BMI) status may help to reduce the associated comorbidities. Although many studies in the literature have investigated the BMI of school adolescents in Malaysia, the data on status of body weight among school adolescents in suburban states like Terengganu is limited. This study aimed to describe the body ...

Few studies examined socioeconomic contributors to racial disparities in low birth weight outcomes between African-American and Caucasian adolescent mothers. This cross-sectional study examined the intersections of maternal racial status, age, and neighborhood socioeconomic status in explaining these disparities in low birth weight outcomes across a statewide sample of adolescent mothers. Using data from the North Carolina State Center of Health Statistics for 2010-2011, birth cases for 16,472 adolescents were geocoded by street address and linked to census-tract information from the 2010 United States Census. Multilevel models with interaction terms were used to identify significant associations between maternal racial status, age, and neighborhood socioeconomic status (as defined by census-tract median household income) and low birth weight outcomes across census tracts. Significant racial differences were identified in which African-American adolescents had greater odds of low birth weight outcomes than Caucasian adolescents (OR=1.88, 95% CI 1.64, 2.15). Although racial disparities in low birth weight outcomes remained significant in context of maternal age and neighborhood socioeconomic status, the greatest disparities were found between African-American and Caucasian adolescents that lived in areas of higher socioeconomic status (psocioeconomic status. Further investigations using intersectional frameworks are needed for examining the relationships between neighborhood socioeconomic status and birth outcome disparities among infants born to adolescent mothers.

Growing body of literature has reported that weight status estimation pattern, including accurate-, under-, and overestimation, was associated with weight related behaviors and weight change among adolescents and young adults. However, there have been a few studies investigating the potential role of school contexts in shaping adolescents' weight status estimation pattern among Korea adolescents. The aim of the present study was to investigate the association between weight status misperception patterns and factors at individual-, family-, and school-level, simultaneously, and whether there was significant between schools variation in the distribution of each weight status misperception pattern, underestimation and overestimation respectively, among Korean adolescents aged 12-18 years. Data from the Eighth Korea Youth Risk Behavior Web-based Survey (KYRBS), 2012, a nationally representative online survey of 72,228 students (boys = 37,229, girls = 34,999) from a total of 797 middle and high schools were used. Sex stratified multilevel random intercept multinomial logistic models where adolescents (level 1) were nested within schools (level 2) were performed. At the school level, attending a school with higher average BMI (kg/m2) was positively associated with weight status underestimation, and inversely associated with weight status overestimation among boys and girls. Single-sex schooling was positively associated with weight status underestimation among girls. At the family level, higher household income (high/middle versus low) was inversely associated with both weight status under- and overestimation among boys and girls. Higher maternal education (equal to or more than college graduate versus equal to or less than high school graduate) was positively associated with weight status overestimation among boys, and living with both parents (compared to not living with both parents) was inversely associated with weight status underestimation among girls.

The aim of our study was to examine the mediation effect of weight status on the association between cardiorespiratory fitness (CRF) and academic performance (AP). Two hundred sixty-nine adolescents (140 boys) aged 13.9 ± 0.3 years old from the DADOS study were included in this cross-sectional analysis. CRF was assessed by the 20-m shuttle run test and estimated maximum oxygen uptake was used in the analysis. AP was assessed through the final academic grades and the Science Research Associates Test of Educational Abilities for assessing reasoning, verbal, and numeric abilities. Weight status was assessed by body mass index (kg/m 2 ). Boot-strapped mediation procedures were performed and indirect effects (IE) with confidence intervals (CI) not including zero were considered statistically significant. Mediation analysis revealed that weight status acted as a mediator of the relationship of CRF with reasoning ability (IE = 0.039; CI = 0.001; 0.091) and the final grades in Math (IE = 0.011; CI = 0.002; 0.025), Language (IE = 0.013; CI = 0.004; 0.027), and GPA (IE = 0.011; CI = 0.003; 0.023). Our data show that the influence of CRF on academic performance is mediated by weight status in adolescents. We suggest that our data could be considered by educators, families, and policy makers, so that active lifestyles might be promoted when designing programs aimed to improve AP among adolescents. What is Known: • Academic performance is associated with both, cardiorespiratory fitness and weight status. • The role of weight status in the association between cardiorespiratory fitness and academic performance is poorly understood. What is New: • We support the scarce research investigating the mediating role of weight status as mechanism in the association between fitness and academic performance in youth. • Previous knowledge is expanded by suggesting that cardiorespiratory fitness is related to weight status which in turn may

This study examined the relationship between adolescent weight status and food advertisement receptivity. Survey-based evaluation with data collected at baseline (initial and at 2 months), and at follow-up (11 months). New Hampshire and Vermont. Students (n = 2,281) aged 10-13 in 2002-2005. Overweight. Generalized estimating equations to model the relationship between identifying a food advertisement as their favorite and being overweight. Overall, 35.9% of the adolescents were overweight. Less than one fifth named a food advertisement as their favorite (16.1%). Most of the food advertisements were for less-healthful food (89.6%). After controlling for school, age, sex, sociodemographics, physical activity, number of TV sessions watched, and having a TV in the bedroom, overweight adolescents were significantly less likely to be receptive to food advertisements (relative risk = 0.83, 95% confidence interval 0.70, 0.98) compared to non-overweight adolescents. This study provides preliminary evidence that normal-weight adolescents are receptive to unhealthful food advertisements. Longitudinal studies are needed to evaluate whether consistent exposure to advertisements for unhealthful food, particularly if they are promoted with healthful behaviors such as being physically active, influence adolescents' food choices, and ultimately their body mass index, over the long term.

Most adolescents consume ≥1 snack/d; exploring the relevance of snacking patterns for overall diet and weight status is important to guide dietary counseling and public health strategies for obesity prevention. This study examined intake of common energy-dense snack foods, total number of snacks consumed, frequency of consuming snacks prepared away from home, and frequency of snacking while watching television in adolescents and how these behaviors may be linked to diet and weight status. Relations were examined with attention to potential confounders that may help explain the mixed findings of previous research. Survey measures of snacking behavior, a food-frequency questionnaire, and anthropometric measurements were completed by 2793 adolescents (53.2% girls, mean age = 14.4 y) in Minneapolis-St. Paul school classrooms in 2009-2010. Linear regression was used to examine associations with adjustment for sociodemographic characteristics and other potential confounding factors, such as meal skipping, underreporting energy intake, dieting to lose weight, and physical activity. Adolescents reported consuming a mean of 2.2 energy-dense snack food servings/d and 4.3 snacks/d and purchasing snacks prepared away from home on 3.2 occasions/wk. More than two-thirds of adolescents reported that they sometimes, usually, or always consumed a snack while watching television. The measures of snacking were directly associated (P snack food servings were not related to sugar-sweetened beverage intake. A direct relation between daily servings of energy-dense snack foods and body mass index (BMI) z score was found; however, the snacking behaviors were inversely related to BMI z score (P snack consumption is a risk factor for poor diet, but unless energy-dense foods are consumed, snacking does not consistently contribute to overweight in US adolescents. © 2016 American Society for Nutrition.

Although many studies in the literature have investigated the BMI of school adolescents in Malaysia, the data on status of body weight among school adolescents in suburban states like Terengganu is limited. This study aimed to describe the body weight status of the whole population of school adolescents in all seven districts in Terengganu, Malaysia. Using a cross-sectional study design, body weight and height were measured, and BMI was calculated and classified using WHO BMI-for-age Z-score. Data was obtained using the National Fitness Standard (SEGAK) assessment, which was uploaded in a specific Health Monitoring System (HEMS). From a total of 62,567 school adolescents, 50.7% were boys and 49.3% were girls. Girls had significantly higher BMI than boys in age groups of 13 to 15 and 16 to 17 years old. Among boys and girls, there were significant differences in mean BMI of school adolescents between rural and urban school locations in all age groups (p < 0.001). There were also significant differences in BMI between boys and girls in all districts in Terengganu, except Kemaman and Kuala Terengganu, for all age groups (p < 0.001). Overall, the prevalence of thinness, normal, overweight and obesity were 8.4, 64.6, 15.0 and 12.0%, respectively. There were significant differences between BMI categories and genders in total participants, and within rural and urban school locations (p < 0.05). In all districts except Marang and Dungun, significant difference was also found between BMI categories and genders. The prevalence of thinness, overweight and obesity in Terengganu were substantial. In this study, BMI category was associated with gender, age, school location and district. However, the actual effects of these factors on the

To describe the association between weight status and sexual practices among 18- to 19-year-old women. We analyzed a population-based longitudinal study of 18- to 19-year-old women residing in a Michigan county at cohort inception. Weekly journal surveys measured sexual practices, including contraceptive behaviors. Outcomes included proportion of weeks with a partner, proportion of weeks with sexual intercourse, number of partners, average length of relationships, proportion of weeks with contraception use, and proportion of weeks where contraception was used consistently. We examined 26,545 journal surveys from 900 women over the first study year. Ordinary least squares regression models for each outcome examined differences by weight status, controlling for sociodemographic characteristics. The mean proportion of weeks in which adolescents reported sexual intercourse was 52%; there was no difference by weight status. Among weeks in which adolescents reported sexual activity, obese adolescents had a lower proportion of weeks where any contraception was used compared with normal weight adolescents (84% vs 91%, P = .011). Among weeks in which adolescents reported sexual activity and contraceptive use, obese adolescents had a lower proportion of weeks with consistent contraceptive use (68% vs 78%, P = .016) and oral contraceptive pill use (27% vs 45%, P = .001) compared with normal weight adolescents. All other relationships by weight status were not statistically significant. In this longitudinal study, obese adolescent women were less likely to use contraception, and less likely to use it consistently when compared with normal weight peers. Findings suggest obesity may be an important factor associated with adolescent women's sexual behavior. Copyright © 2015 The Authors. Published by Elsevier Inc. All rights reserved.

The aim of this study was to determine if a potential relationship among physical activity (PA), fundamental movement skills and weight status exists amongst early adolescent youth. Participants were a sample of 85 students; 54 boys (mean age = 12.94 ± 0.33 years) and 31 girls (mean age = 12.75 ± 0.43 years). Data gathered during physical education class included PA (accelerometry), fundamental movement skills and anthropometric measurements. Standard multiple regression revealed that PA and total fundamental movement skill proficiency scores explained 16.5% (P fundamental movement skills. Results from the current investigation indicate that weight status is an important correlate of fundamental movement skill proficiency during adolescence. Aligned with most recent research, school- and community-based programmes that include developmentally structured learning experiences delivered by specialists can significantly improve fundamental movement skill proficiency in youth.

To identify the association between pre-gestational nutritional status, maternal weight gain, and prenatal care with low birth weight (LBW) and prematurity outcomes in infants of adolescent mothers. Cross-sectional study with 542 pairs of adolescent mothers and their children attending a public maternity hospital in Rio de Janeiro. Data were collected from medical records. To determine the association between independent variables and the outcomes studied, odds ratio (OR) and a 95% confidence interval (CI) were estimated With respect to pre-pregnancy nutritional status of adolescents, 87% had normal weight, 1% were underweight, 10% were overweight, and 2% obese. Inadequate total gestational weight gain (72%) exceeded adequacy (28%). Birth weight was favored with greater gestational weight gain, and reduced with late onset of prenatal care. The comparison between the low birth weight and normal birth weight groups revealed significant differences between variable means: interval between the past pregnancy and current pregnancy (p = 0.022), pre-gestational weight (p = 0.018); pre-gestational body mass index (p pregnancy weight and body mass index before pregnancy. The minimum frequency of six prenatal care visits was a protective factor against LBW and prematurity.

Purpose. The purpose of this study was to assess rural and urban differences in the dietary intakes, physical activity levels and weight status of a large sample of Canadian youth in both 2005 and 2008. Materials and Methods. A cross-sectional study of rural and urban adolescents (n = 10, 023) in Alberta was conducted in both 2005 and 2008 using a web-based survey. Results. There was an overall positive change in nutrient intakes between 2005 and 2008; however, rural residents generally had a poorer nutrient profile than urban residents (P < .001). They consumed less fibre and a greater percent energy from saturated fat. The mean physical activity scores increased among rural youth between 2005 and 2008 (P < .001), while remaining unchanged among urban youth. Residence was significantly related to weight status in 2005 (P = .017), but not in 2008. Conclusion. Although there were small improvements in nutrient intakes from 2005 to 2008, several differences in the lifestyle behaviours of adolescents living in rural and urban areas were found. The results of this study emphasize the importance of making policy and program recommendations to support healthy lifestyle behaviours within the context of the environments in which adolescents live.

We also examined the roles of age, gender, weight, treatment condition, and psychosocial variables (psychopathological symptoms, social support, and emotional skills in the presence of those risk behaviors. Our major findings were that the clinical group of overweight adolescents had fewer risk behaviors, than the overweight community group and the normal weight controls, particularly for risk behaviors related to alcohol use. The increase of age and lower satisfaction with family predicted tobacco consumption. The increase of age, not being integrated in a treatment for weight control and higher satisfaction with intimate relationships predicted alcohol consumption. Weight status was not a predictor of alcohol and cigarette use. This study discusses the theoretical and practical implications of these findings.

Changes in weight status from adolescence to adulthood may be associated with varying social, vocational, economic, and educational outcomes, which may differ by sex. We studied whether there are differences in adult outcomes by sex for different weight status changes in the transition to adulthood. Using data from the National Longitudinal Study of Adolescent Health, participants were categorized by weight status from adolescence into adulthood. We examined self-reported outcomes in adulthood for living with parents, being married, being a parent, employment, receipt of public assistance, income, and college graduation by weight groupings (healthy-healthy, healthy-overweight/obese, overweight/obese-overweight/obese, overweight/obese-healthy). The effect of changes in weight status on the adult outcomes was modeled, controlling for sex, age, parental education, and race/ethnicity. There were differences by sex for many of the self-reported outcomes, especially educational and economic outcomes. Female subjects who became overweight/obese between adolescence and adulthood or remained so had worse economic and educational findings as adults compared to male subjects. Overall, for female subjects, becoming and remaining overweight/obese was associated with worse outcomes, while for male subjects, adolescent obesity was more important than isolated adult obesity. The relationship between obesity and life situations may be more negative for female subjects in the transition to adulthood. The findings emphasize that adolescent obesity, and not just obesity isolated in adulthood, is important for characteristics achieved in adulthood. Copyright © 2014 Academic Pediatric Association.

To investigate precursors to gender-related obesity disparities by examining multiple family-level stress indices. Analyses was based on adolescents born between 1975 and 1991 to women from the 1979 National Longitudinal Study of Youth data set (N=4762). Three types of family-level stressors were captured from birth to age 15: family disruption and conflict, financial strain, and maternal risky health behaviors, along with a total cumulative risk index. Body mass index was constructed on reference criteria for children outlined by the Centers for Disease Control. Multivariate logistic regressions were conducted for the three types of family stressors and for the total cumulative index. The accumulation of family disruption and conflict and financial stress was positively related to female adolescents being overweight/obese. Childhood exposure to maternal risky health behaviors was positively associated with higher weight status for male adolescents. Total cumulative stress was related to overweight/obesity for females, but not males. Different family-level stress indices are associated with the weight status of female and male adolescents. Combining types of family-level stress into one cumulative index appears to mask these differences. Copyright © 2015 Elsevier Inc. All rights reserved.

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

Healthy behaviors including limited screen time (ST), high physical activity (PA), and adequate fruits and vegetables consumption (FV) are recommended for adolescents, but it is unclear how gender, race/ethnicity, and weight status relate to these public health guidelines in diverse urban adolescents. Participants (N = 384) were recruited from three public high schools in or near New Haven, Connecticut. Descriptive statistics and logistic regression analyses were conducted. Most adolescents exceeded recommended levels of ST (70.5%) and did not meet guidelines for PA (87.2%) and FV (72.6%). Only 3.5% of the sample met all three guidelines. Boys were more likely to meet guidelines for PA (p differences in meeting ST, PA, or FV guidelines by weight status for the overall sample or when stratified by gender or race/ethnicity. We found alarmingly low levels of healthy behaviors in normal weight and overweight/obese adolescents. © The Author(s) 2014.

Some studies have investigated the association between body mass index (BMI) and health-related quality of life (HRQoL) among adolescents, but their results have been discrepant and few paid attention to the role of gender. The present investigation aimed to assess the relationship between weight status and HRQoL in adolescents and to verify whether it was similar in boys and girls. Five thousand two hundred and twenty six adolescents aged 14 to 18 years were included in the PRomotion de l'ALIMentation et de l'Activité Physique (PRALIMAP) trial, a 2x2x2 factorial cluster randomized trial performed in 24 high schools in France. Sociodemographic, anthropometric and HRQoL data were collected. BMI was categorized in four classes (thin, normal-weight, overweight, obese). Linear regression models were used to estimate the association between weight status and HRQoL, adjusting for confounders. The mean age of adolescents was 15.7±0.6 years and their mean BMI was 21.6 ±3.5 kg/m2; 55% were girls. Boys were more often overweight and obese than were girls (overweight: 15.6% vs 14.2%, obese: 4.8% vs 3.3%), and girls were more likely to be thin (5.5% vs 4.5%, p=0.0042). All HRQoL scores were higher for boys (p=Gender can modify the association between weight status and HRQoL in adolescents. Body image could be an important target of public health programs to improve subjective health during adolescence.

Little is known about how factors within the general family environment are associated with weight and related behaviors among adolescents/young adults. We studied 3768 females and 2614 males, 14-24 years old in 2011, participating in the Growing Up Today Study 2. We used generalized mixed models to examine cross-sectional associations of family functioning and quality of mother- and father-adolescent relationship with adolescent/young adult weight status, disordered eating, intake of fast food and sugar-sweetened beverages, screen time, physical activity, and sleep duration. In all models, we included participant's age and family structure. Eighty percent of participants reported high family functioning and 60% and 50% of participants reported high-quality mother and father relationship, respectively. Among both males and females, high family functioning was associated with lower odds of disordered eating (adjusted odds ratio [AOR] females = 0.53; 95% Confidence Interval [CI] = 0.45-0.63; AOR males = 0.48; CI = 0.39-0.60), insufficient physical activity, i.e., less than 1 h/day, (AOR females = 0.74; CI = 0.61-0.89; AOR males = 0.73; CI = 0.58-0.92), and insufficient sleep, i.e., less than 7 h/day, (AOR females = 0.56; CI = 0.45-0.68; AOR males = 0.65; CI 0.5-0.85). High family functioning was also associated with lower odds of being overweight/obese (AOR = 0.73; CI = 0.60-0.88) and eating fast food one or more times/week (AOR = 0.74; CI = 0.61-0.89) among females only. Among females, high-quality mother and father relationship were both associated with lower odds of being overweight/obese and disordered eating, eating fast food, and insufficient sleep and the magnitude of associations were similar for mother and father relationship quality (AOR range 0.61-0.84). Among males, high-quality mother and father relationship were both associated with lower odds of disordered eating, insufficient physical activity

Although most eating occurs in a social context, the effects of peer influence on child eating have not been the object of systematic experimental study. The present study assesses the effects of peer influence on lean and overweight pre-adolescent girls' snack intake as a function of the co-eaters' weight status. The weight status of the participants was varied by studying weight discordant dyads (i.e., one lean and one overweight participant) and weight concordant dyads (i.e., both members of the dyads were either lean or overweight). Results from the random regression model indicate that overweight girls eating with an overweight peer consumed more kilocalories than overweight participants eating with a normal-weight peer. Normal-weight participants eating with overweight peers ate similar amounts as those eating with lean eating companions. The regression model improved when the partners' food intake was entered in the model, indicating that the peers' intake was a significant predictor of participants' snack consumption. This study underscores differences in responses to the social environment between overweight and non-overweight youths.

To explore 10-year longitudinal predictors (personal, psychological, behavioral, and socioenvironmental) of exiting obesity from adolescence to young adulthood. Data were collected from a population-based cohort of adolescents (n = 2,287) attending middle/high schools in Minneapolis-St. Paul in 1998-1999 (mean age = 14.9) and again in 2008-2009 (mean age = 25.3) participating in Project Eating and Activity Among Teens and Young Adults. Self-reported height and weight were used to calculate weight status change between adolescence and young adulthood, among participants with obesity at baseline (n = 175). Questionnaires assessed personal, psychological, behavioral, and socioenvironmental factors hypothesized to play a role in obesity. Modified Poisson regressions estimated adjusted relative risks (RRs) for exiting obesity as a function of each baseline and 10-year change in predictor, controlling for relevant covariates. Thirty-two percent of adolescents exited obesity in young adulthood. Reductions in fast food intake (RR = .73, 95% confidence interval [CI] = .61-.87) and screen time (RR = .98, 95% CI = .96-.99), and increases in fruit/vegetable intake (RR = 1.06, 95% CI 1.01-1.12), moderate-to-vigorous physical activity (RR = 1.06, 95% CI = 1.00-1.12), home fruit/vegetable availability (RR = 1.58, 95% CI = 1.19-2.09), family meals (RR = 1.12, 95% CI = 1.03-1.22), and serving vegetables at dinner (RR = 1.45, 95% CI = 1.10-1.92) were associated with exiting obesity. Not dieting as an adolescent and improvements in body satisfaction, depressive symptoms, self-esteem, and weight teasing were also associated with exiting obesity. Promoting healthy eating and activity, and improving the healthfulness of home food environments may be promising intervention targets for promoting healthier weights in adolescents and young adults with obesity. Addressing dieting behavior and the psychosocial health of adolescents with obesity may also be needed throughout

This study examined weight status as a moderator of the relationship between motivation (controlled, autonomous, regulatory), emotional social support (parents, peers) and moderate-to-vigorous physical activity (MVPA) in underserved adolescents (ethnic minority, low-income). Participants from the Active by Choice Today Trial (n = 1,416; 54% girls, 73% African American, 52% overweight/obese) completed baseline measures, including height and weight, psychosocial surveys, and 7-day accelerometry estimates. Weight status was defined by body mass index z-score (zBMI). Weight status moderated the effects of controlled, autonomous, and regulatory motivation on MVPA, such that these variables were more strongly associated with MVPA in adolescents with lower versus higher zBMI scores. A better understanding of why motivation is not related to MVPA in underserved youth with a higher weight status is needed. Future pediatric obesity treatment in underserved youth may need to move beyond motivation into environmental factors associated with long-term behavior change.

The aim of this study was to investigate the relation between health-related physical fitness and weight status in 13- to 15-year-old Latino adolescents. The final sample consisted of 73,561 adolescents aged 13-15 years (35,175 girls) from Chile (n=48,771) and Colombia (n=24,790). Cardiorespiratory and musculoskeletal fitness were measured using 20-m shuttle run (relative peak oxygen uptake - VO 2peak ) and standing broad jump test (lower body explosive strength), respectively. The International Obesity Task Force definition was used to define weight status (i.e., underweight, normal weight, overweight, and obese). The present study found an inverted J-shape relationship between body mass index, cardiorespiratory fitness, and musculoskeletal fitness in both genders and all age groups (pfitness (based on new international criterion-referenced standards) profile when compared with their normal weight peers, except in girls aged 14 (p=0.268) and 15 years (p=0.280). The present results indicate low cardiorespiratory fitness and musculoskeletal fitness levels in underweight, overweight, and obese adolescents when compared with their normal weight peers. The findings appear to suggest that exercise programs should to decrease fat mass in overweight/obese adolescents and increase muscle mass in underweight adolescents.

Full Text Available Adolescents’ self-control weight behaviors were assessed (n= 1961; 12-17 years old; 2007-2008 in the Balearic Islands, Spain. The study analyzed the relationships between body weight status, body image and self-weight concern, and actual attempts to lose weight by restrained eating and/or increased exercising. In terms of regulatory focus theory (RFT, we considered that efforts to lose or to maintain weight (successful or failed would be motivated either by a promotion focus (to show an attractive body, a prevention focus (to avoid social rejection of fatness, or both. Results showed that 41% of overweight boys and 25% of obese boys stated that they had never made any attempt to lose weight, and 13% and 4% in females. Around half of overweight boys and around a quarter of obese boys stated that they were Not at all concerned about weight gain, and girls’ percentages decreased to 13% and 11% respectively. By contrast 57% of normal weight girls monitored their weight and stated that they had tried to slim at least once. Weight self-regulation in females attempted to combine diet and exercise, while boys relied almost exclusively on exercise. Apparent lack of consciousness of body weight status among overweight boys, and more important, subsequent absence of behaviors to reduce their weight clearly challenges efforts to prevent obesity. We argue that several causes may be involved in this outcome, including unconscious emotional (self-defense and cognitive (dissonance mechanisms driven by perceived social stigmatization of obesity. The active participation of social values of male and female body image (strong vs. pretty and the existence of social habituation to overweight are suggested. A better knowledge of psychosocial mechanisms underlying adolescent weight self-control may improve obesity epidemics.

The aim of this study was to examine the relationship of weight status, physical activity and screen time with academic achievement in Chilean adolescents. The present cross-sectional study included 395 adolescents. The International Obesity Task Force cut-off points were used to define the weight status. Physical activity was assessed using the Physical Activity Questionnaire for Adolescents and screen time was assessed using several questions about television, videogame and computer use. Academic achievement was measured using the mean of the grades obtained in mathematics and language subjects. In both genders, adolescents with obesity and excessive screen time earned worse grades compared to their non-obese peers and their peers that complied with screen time recommendations. The logistic regression analysis showed that adolescents with obesity, classified with medium-low physical activity and excessive screen time recommendations (excess ≥2h/day) are less likely to obtain high academic achievement (boys: OR=0.26; girls: OR=0.23) compared to their non-obese peers, high levels of physical activity and those who comply with the current screen time recommendations. Similar results were observed in adolescents with obesity and classified with medium-low physical activity (boys: OR=0.46; girls: OR=0.33) or excessive screen time (boys: OR=0.35; girls: OR=0.36) compared to adolescents with high levels of physical activity and those who complied with the screen time recommendations, respectively. This study shows that when combined, obesity, low-medium levels of physical activity and excessive screen time might be related to poor academic achievement.

Full Text Available Abstract Background The underlying mechanisms of overweight and obesity in adolescents are still not fully understood. The aim of this study was to investigate modifiable and non-modifiable correlates of weight status among 1103 Norwegian 11-year-old adolescents in the HEalth in Adolescents (HEIA study, including demographic factors such as gender and parental education, and behavioral factors such as intake of sugar-sweetened beverages, snacks and breakfast consumption, watching TV and playing computer games, physical activity and sedentary time. Methods Weight and height were measured objectively, body mass index (BMI was calculated and International Obesity Task Force cut-offs were used to define weight status. Physical activity and sedentary time were measured by accelerometers. Other behavioral correlates and pubertal status were self-reported by questionnaires. Parental education was reported by the parents on the consent form for their child. Associations were investigated using logistic regressions. Results There were gender differences in behavioral correlates of weight status but not for weight status itself. Adolescents with parents in the highest education category had a 46% reduced odds of being overweight compared to adolescents with parents in the lowest education category. Adolescents with parents with medium education had 42% lower odds of being overweight than adolescents with parents with the lowest education category. Level of parental education, breakfast consumption and moderate to vigorous physical activity were positively associated with being normal weight, and time watching TV was positively associated with being overweight for the total sample. Gender differences were detected; boys had a doubled risk of being overweight for every additional hour of watching TV per week, while for girls there was no association. Conclusions The present study showed a social gradient in weight status in 11-year-olds. Both breakfast

Full Text Available This paper investigated weight misperceptions as determinants of racial/ethnic disparities in body mass index (BMI among adolescent females using data from the National Survey of Youth 1997. Compared to their white counterparts, higher proportions of black and Hispanic adolescent females underperceived their weight status; that is, they misperceived themselves to have lower weight status compared to their clinically defined weight status. Compared to their black counterparts, higher proportions of white and Hispanic adolescent females misperceived themselves to be heavier than their clinical weight status. Oaxaca-Blinder decomposition analysis showed that accounting for weight misperceptions, in addition to individual and contextual factors, increased the total explained portion of the black-white female BMI gap from 44.7% to 54.3% but only slightly increased the total explained portion of the Hispanic-white gap from 62.8% to 63.1%. Weight misperceptions explained 13.0% of the black-white female BMI gap and 3.3% of the Hispanic-white female BMI gap. The regression estimates showed that weight underperceptions were important determinants of adolescent female BMI, particularly among black and Hispanic adolescents. Education regarding identification and interpretation of weight status may play an important role to help reduce the incidence and racial disparity of female adolescent obesity.

The primary objective of this study was to predict weight status stability and change across the transition to adolescence using parent reports of child and household routines and teacher and child self-reports of social-emotional development. Data were from the Early Childhood Longitudinal Study-Kindergarten Cohort (ECLS-K), a nationally representative sample of children who entered kindergarten during 1998-1999 and were followed through eighth grade. At fifth grade, parents reported on child and household routines and the study child and his/her primary classroom teacher reported on the child's social-emotional functioning. At fifth and eighth grade, children were directly weighed and measured at school. Nine mutually-exclusive weight trajectory groups were created to capture stability or change in weight status from fifth to eighth grade: (1) stable obese (ObeSta); (2) obese to overweight (ObePos1); (3) obese to healthy (ObePos2); (4) stable overweight (OverSta); (5) overweight to healthy (OverPos); (6) overweight to obese (OverNeg); (7) stable healthy (HelSta); (8) healthy to overweight (HelNeg1); and (9) healthy to obese (HelNeg2). Except for breakfast consumption at home, school-provided lunches, nighttime sleep duration, household and child routines did not predict stability or change in weight status. Instead, weight status trajectory across the transition to adolescence was significantly predicted by measures of social-emotional functioning at fifth grade. Assessing children's social-emotional well-being in addition to their lifestyle routines during the transition to adolescence is a noteworthy direction for adolescent obesity prevention and intervention.

Overweight and obesity has high prevalence in children and adolescents in Spain. To determine the degree of influence of four modifiable factors (dietary habits, physical activity, sedentary and sleep) jointly on the weight status of a group of school children and adolescents in Madrid. 189 schoolchildren aged 6 to 16 years, who underwent an anthropometric study. To exercise the IPAQ questionnaire was used, establishing a minimum of one hour of exercise a day, as a recommendation, and two hours per day in case of sedentary, which took into account the hours of computer, consoles and TV. Sleep quality was assessed by collecting sleeping hours weekdays and weekend nap. Stating that school children should sleep 10 hours a day. The KIDMED Index was used for the diet quality, the score can be accessed from 0-12 and classified into 3 categories, it was regrouped for statistical measure. The first two results (0-7) as "Bad adherence" and ≥ 8 value as "Good adherence". 27.6% of students had excess weight. No significant differences were reported analyzing the four factors studied versus weight status among those who keep recommendations and excess weight, either individually or multifactor analysis was observed.

Mexican American children are disproportionately affected by obesity. Data on how the acculturation process influences diet and body weight among adolescents are limited. We used the data from the 1999-2004 NHANES, restricting to 2286 Mexican American children between 12 and 19 y old. Acculturation was measured by generation status and language preference. Diet was assessed using 24-h diet recall. Multiple linear, Tobit, logistic, and quantile regression models were used. We found, after adjusting for socio-demographic factors, health, dietary intake, physical activity, and sedentary behaviors compared to the first generation, second and third generations had greater odds of overweight and obesity. Adolescents in the second generation had higher BMI Z-scores than adolescents in the first and third generations. Both second and third generation adolescents consumed less fruit, whole fruit, vegetables, grains, and meats but more sweetened beverages, whole grains, saturated fat, sodium, oil, and energy from discretionary foods. Higher language acculturation was associated with poorer diet and greater body weight. Our findings suggest that Mexican American adolescents face challenges in terms of poorer diet and excessive weight gain associated with their immigration experience.

Adolescents in modern societies spend about 3 h per day in front of small recreational screens. The present study aims at investigating the relationships between screen time and different indicators of overweight. In addition, associations with the self-concept of physical attractiveness and perceived weight status will be examined. In a total sample of 1228 students (47.5% girls) aged 12-17 years (M = 13.74, SD = 0.68) cross-sectional associations were determined by conducting multiple linear regression analyses. Screen time showed a significant positive dose-response relationship with body mass index percentile, waist circumference, body fat, waist-to-height-ratio, and a negative association with self-concept of physical attractiveness independent of age, gender and moderate to vigorous physical activity. Thus, screen time seems to be associated with adolescent overweight, abdominal obesity, and body dissatisfaction. Reducing adolescents' screen time could be a promising approach for primary prevention of obesity and for the promotion of a positive physical self-concept.

To associate the nutritional status and the self-perception of nutritional status with the use of licit drugs among adolescents. Cross-sectional study in which 210 adolescents answered a questionnaire on alcohol and tobacco experimentation and self-perceptions about their nutritional status. The correspondence between the adolescents' perception of their own nutritional status and actual nutritional status was analyzed, as well as associations between nutritional status, self-perception of nutritional status, gender, age, and presence of smokers at home with alcohol and tobacco use. The variables were analyzed separately in a bivariate analysis and, subsequently, a multivariate analysis determined the factors associated with drug use. The study included 210 adolescents with a median age of 148 months; 56.6% were females. Of the total sample, 6.6% have tried cigarettes, and 20% have tried alcohol; 32.3% had BMI Z-Score≥1, 12.85% had BMI Z-Score≥2, and 50.7% had a correct perception of his/her weight. After a multivariate analysis, only the self-perception about weight statistically influenced experimentation of tobacco, and patients who identified themselves as having very high weight were more likely to experiment tobacco (odds ratio (OR) 13.57; confidence interval (95% CI) 2.05-89.8; p=0.007); regarding alcohol use, adolescents who identified themselves as having high weight were 2.4 times more likely to experiment with alcohol than adolescents that identified themselves as having normal weight (95% CI 1.08-5.32, p=0.031). Adolescents with self-perception of excess weight may constitute a risk group for alcohol and tobacco use. Copyright © 2015 Sociedade de Pediatria de São Paulo. Publicado por Elsevier Editora Ltda.

APPLE Schools is a Comprehensive School Health (CSH) project, started in schools in socioeconomically disadvantaged areas where dietary habits are poor, physical activity (PA) levels are low, and obesity rates are high. Earlier research showed program effects whereby energy intake, PA and weight status of students in APPLE Schools had reached similar levels as that of students in other schools. However, it is unknown whether the effects of CSH are sustained when children grow into adolescents. Effects of APPLE Schools on health-related knowledge, attitudes, self-efficacy, diet, PA, and weight status, seven years after the start of the project, when students were in junior high and high school were assessed. We hypothesised that APPLE School graduates and comparison school graduates will remain at similar levels for these indicators. In the 2015/16 school year, junior high and high school graduates (grades 7-12) in Northern Alberta, Canada participated in a Youth Health Survey. Participants included graduates from APPLE elementary schools (n = 202) and comparison elementary schools (n = 338). Health-related knowledge, attitudes, self-efficacy, diet (24-h dietary recall), PA (pedometer step count) and weight status were assessed. Mixed effects regression was employed to assess differences in these outcomes between APPLE School graduates and comparison school graduates. Comparisons between elementary school (2008/09) and junior high/high school (2015/16) of self-efficacy, PA and weight status were also conducted. APPLE School graduates did not significantly differ from comparison school graduates on any outcomes (i.e. knowledge, attitudes, self-efficacy, diet, PA, and weight status). Additionally, no significant differences existed in the comparisons between 2008/09 and 2015/16. Our findings of no difference between the APPLE School graduates and comparison school graduates suggest that the effects of APPLE Schools may continue into adolescence or the new
Full Text Available Abstract Background Despite the global obesity epidemic, few studies have performed cross-national comparisons of adolescents' attempts to lose weight and weight control practices. This study aims to investigate matters mentioned above by weight status in Europe, Israel, and North America. Methods Nationally representative samples of adolescents from over 30 countries completed an anonymous, standardized questionnaire as part of the Health Behaviour in School-aged Children 2001/2002 survey. The prevalence and likelihood of attempts to lose weight were determined. The effect of weight status, self-perception of overweight, age and country of residence upon the likelihood of current attempts to lose weight were evaluated using multilevel multivariate logistic regression in separate analyses for boys and girls. The study also presented the prevalence of weight control practices of overweight and non-overweight adolescents who had controlled their weight in seven countries. Results In general, overweight and obese adolescents were more likely to be engaged in current attempts to lose weight and had tried to control their weight during the past 12 months more often than non-overweight adolescents. Besides weight status, self-perception of overweight and age were significant individual-level factors determining current attempts to lose weight. Country of residence was a significant second-level factor but no clear geographical pattern was found. Several gender-related differences existed. Conclusion The findings indicated that most overweight adolescents were motivated to reduce their weight. The importance of promoting a healthy body image for all adolescents was highlighted by the fact that self-perception of overweight was found to be the most important factor leading to attempts to lose weight.

To explore the association between emotion-driven impulsiveness, cognitive inflexibility, decision-making and weight status as reflected in body mass index (BMI) z-score (zBMI) in European adolescents. In total, 3354 adolescents aged between 12 and 18 years from the I.Family cohort completed the questionnaire-based negative urgency subscale from the UPPS-P Impulsive Behavior Scale to measure emotion-driven impulsiveness in 2013/2014. Furthermore, 1584 adolescents completed the computer-based Bergs Card Sorting Test to measure cognitive inflexibility, and 1780 adolescents completed the Hungry Donkey Test to assess decision-making ability. Anthropometric variables were measured objectively; confounding variables (age, sex, socioeconomic status and country) were assessed using a questionnaire. Mixed-effect regression analyses were conducted for each outcome of the test or questionnaire as a predictor with standardised BMI (zBMI) as the dependent variable in order to investigate association between markers of cognitive functioning and zBMI. After controlling for confounders, results showed that emotion-driven impulsiveness (β=0.18, 95% confidence interval (CI): 0.13 to 0.24, Pdecision-making ability was not significantly related to zBMI (β=0.001, 95% CI: -0.001 to 0.003, P=0.47). More emotion-driven impulsiveness and reduced cognitive flexibility were associated with a higher zBMI in adolescents across Europe. These results may indicate that being impulsive in negative situations and having difficulties changing mental sets increase the susceptibility for unhealthy weight development. Reducing impulsivity and training cognitive flexibility seem promising targets for the prevention and intervention programmes of obesity.International Journal of Obesity advance online publication, 9 January 2018; doi:10.1038/ijo.2017.270.

To determine whether school context influences the BMI of adolescent males and females. Our sample was 17,007 adolescents (aged 12-19) from the National Longitudinal Study of Adolescent Health (Add Health). We used gender-stratified multilevel modeling to examine the contribution of schools to the overall variance in adolescent BMIs, calculated from self-reported weight and height. We then examined the associations of individual attributes with BMI after controlling for the average BMI of the school and the association of two school-level variables with BMI. Participants attended schools that were segregated by race/ethnicity and socioeconomic status (SES). In females, when controlling only for individual-level attributes, individual household income was inversely associated (beta = -0.043, P = 0.01) while Hispanic (beta = 0.89, P school racial/ethnic makeup and the school level median household income, the relationship between individual race/ethnicity and BMI was attenuated in both male and female adolescents. Higher school level median household income was associated with lower individual BMIs in adolescent girls (gamma = -0.37, P school. Male and female adolescents attending schools with higher median household incomes have on average lower BMIs. Resources available to or cultural norms within schools may constitute critical mechanisms through which schools impact the BMI of their students.

The prevalence of overweight and obesity in children has reached a concerning plateau in the past three decades, with overweight or obesity impacting approximately one-third of youth. Unhealthy weight-related behaviors, including dieting, unhealthy weight control practices and binge eating, are also a great public health concern for young people given both their high prevalence and harmful consequences. Food-related parenting practices, including food restriction and pressure-to-eat, have been associated with higher weight status, as well as the use of unhealthy weight-related behaviors, in children and adolescents. Physicians and other health care providers who work with families should discourage parents from using food restriction and pressure-to-eat parenting practices with their child or adolescent. Alternatively, parents should be empowered to promote healthy eating by focusing on making nutritious food items readily available within their home and modeling healthy food choices for their child or adolescent.

Full Text Available Abstract Background This study aimed to canvass the nature of adolescent-parent interactions about weight, particularly overweight, and to explore ideas of how to foster supportive discussions regarding weight, both in the home and with family doctors. Methods A market research company was contracted to recruit and conduct a series of separate focus groups with adolescents and unrelated parents of adolescents from low-middle socio-economic areas in Sydney and a regional centre, Australia. Group discussions were audio recorded, transcribed, and then a qualitative content analysis of the data was performed. Results Nine focus groups were conducted; two were held with girls (n = 13, three with boys (n = 18, and four with parents (20 mothers, 12 fathers. Adolescent and parent descriptions of weight-related interactions could be classified into three distinct approaches: indirect/cautious (i.e. focus on eating or physical activity behaviors without discussing weight specifically; direct/open (i.e. body weight was discussed; and never/rarely discussing the subject. Indirect approaches were described most frequently by both adolescents and parents and were generally preferred over direct approaches. Parents and adolescents were circumspect but generally supportive of the potential role for family doctors to monitor and discuss adolescent weight status. Conclusions These findings have implications for developing acceptable messages for adolescent and family overweight prevention and treatment interventions.

Full Text Available Background : To investigate the agreements between actual and perceived body weight status among adolescents and to identify the associations of disagreements with their weight control behaviors. Methods : This study used the secondary data of a sample survey (n=13,871 of the Seoul Student Health Examination among middle and high schools in 2010. Agreements between actual (underweight, normal, overweight, and obese, according to 2007 Korean National Growth Charts and perceived body weight status (underweight, normal, overweight, and obese were examined using Chi-square and Cohen’s kappa agreement, and then multinomial logistic regression including gender, grade, and attempt of weight control or method of weight control was done. Results : Agreements between actual and perceived body weight status were only 45.2%, and disagreements were up to 54.8%, including mild over- (20.4%, severe over- (1.8%, mild under- (29.5%, and severe under-estimation (3.1%. The kappa coefficient of agreement was only 0.19. The odds ratios on severe over-estimated perception were 1.59 (95% CI, 1.22-2.07 in female subjects, 1.78 (95% CI, 1.36-2.34 in diet control behaviors, and 1.53 (95% CI, 1.18-2.00 in exercise. The odds ratios on severe under-estimated perception were only 0.40 (95% CI, 0.32–0.50 in female subjects but 5.77 (95% CI, 3.68-9.06 in taking medication. Conclusion : There were associations of body weight control behaviors with disagreements of actual and perceived weight status. Therefore, further study is needed to identify the weight disagreement-related factors and to promote the desired weight control behaviors for adolescents.

We investigated the relationship between being bullied and measured body weight and perceived body weight among adolescents of a middle-income sub Saharan African country. Our data originated from the Global School-based Health Survey, which targets adolescents aged 13-15 years. Student weights and heights were measured before administrating the questionnaire which included questions about personal data, health behaviors and being bullied. Standard criteria were used to assess thinness, overweight and obesity. Among 1,006 participants who had complete data, 16.5% (95%CI 13.3-20.2) reported being bullied ≥ 3 days during the past 30 days; 13.4% were thin, 16.8% were overweight and 7.6% were obese. Categories of actual weight and of perceived weight correlated only moderately (Spearman correlation coefficient 0.37 for boys and 0.57 for girls; p < 0.001). In univariate analysis, both actual obesity (OR 1.76; p = 0.051) and perception of high weight (OR 1.63 for "slightly overweight"; OR 2.74 for "very overweight", both p < 0.05) were associated with being bullied. In multivariate analysis, ORs for categories of perceived overweight were virtually unchanged while ORs for actual overweight and obesity were substantially attenuated, suggesting a substantial role of perceived weight in the association with being bullied. Actual underweight and perceived thinness also tended to be associated with being bullied, although not significantly. Our findings suggest that more research attention be given to disentangling the significant association between body image, overweight and bullying among adolescents. Further studies in diverse populations are warranted.

Accurate perception of one's weight status is believed to be necessary to motivate weight loss intention and subsequent weight loss among those with overweight/obesity. This proposed pathway, however, is understudied in longitudinal research. This study examined the indirect effect of weight change intention on the relationship between weight status perception and BMI change among adolescents with overweight/obesity. Participants included 2664 adolescents with overweight/obesity (52% female) from the National Longitudinal Study of Adolescent Health. Longitudinal associations between Wave II weight status perception (accurate versus misperception) and intent to change weight (i.e., gain, lose, stay the same) on BMI change (Wave II-Wave IV) were examined using multiple linear regression. Indirect effects of weight change intention were investigated using the Monte Carlo method. Analyses were stratified by gender. Accurate perceivers (81.0% female; 60.1% male) were more likely than misperceivers (i.e., perception of "about the right weight") to report weight loss intention (p<0.001). Among females, weight status misperception and weight loss intention individually were associated with smaller (β=-1.37, 95% CI [-2.64, -0.10]) and greater (β=1.18, 95% CI [0.11, 2.25]) BMI gains, respectively. Among males, fully adjusted models suggested that weight status misperception was associated with significantly smaller gains in BMI over time (β=-1.51, 95% CI [-2.38, -0.63]). Weight change intention did not emerge as an indirect effect for either gender. Although weight status misperception was protective against weight gain, weight change intention did not provide an explanation for this relationship. Copyright © 2017 Elsevier Ltd.

The study examined the association of neighborhood walkability to multiple activity-related outcomes and BMI among adolescents and evaluated socioeconomic status as an effect modifier. Cross-sectional study, with adolescents recruited from neighborhoods that met criteria for a 2 × 2 matrix defined by high/low GIS-defined walkability and high/low median income. Adolescents aged 12-16 years (n = 928) were recruited from selected neighborhoods in Maryland and King County, Washington regions in 2009-2011. There were 50.4% girls, and 66.3% were non-Hispanic white, with no medical restrictions on physical activity (PA) or diets. Total PA and sedentary time was assessed by 7 days of accelerometer monitoring. Adolescents self-reported active transport, time spent on 6 sedentary behaviors, and height and weight, used to compute BMI percentiles. Mixed model linear and logistic regressions examined outcomes for association with walkability and income, adjusting for demographic covariates and clustering within block groups. Walkability was positively and significantly related to objectively-measured PA (p < .001) and more frequent walking for transportation (p < .001). Total self-reported sedentary time (p = .048) and TV time (p < .007) were negatively related to walkability. Time in vehicles was negatively related to walkability only among higher-income adolescents. Neighborhood walkability was strongly and consistently associated with adolescents' objectively-assessed total physical activity and reported active transportation. A novel finding was that adolescents living in walkable neighborhoods reported less television time and less time in vehicles. Most results were similar across income categories. Results strengthen the rationale for recommendations to improve walkability. Copyright © 2018 Elsevier Inc. All rights reserved.

To assess whether the indicators of weight status body mass index and waist-to-height ratio are similar to body fat percentage to identify obese children and adolescents with unfavorable lipid profile. This was a cross-sectional study involving 840 children and adolescents (6-18 years). The same individuals were classified as non-obese (
weight status, body mass index, and waist-to-height ratio. Body fat percentage was obtained by multi-frequency bioelectrical impedance. Linear association between obesity and increased lipid fractions was tested by ANCOVA. Normal distribution curves of non-HDL cholesterol were designed for obese and non-obese. To provide the proportion of obese individuals with elevated non-HDL-c across all indicators, Z-score was calculated. Obese boys presented higher non-HDL cholesterol when compared with those non-obese, classified by body mass index (107±28 vs. 94±25mg/dL, p=0.001), waist-to-height ratio (115±29 vs. 94±25mg/dL, p<0.001) and body fat percentage (119±33 vs. 94±24mg/dL, p<0.001). Differently, obese girls presented with higher non-HDL cholesterol when compared with those non-obese only according to the body fat percentage classification (118±24 vs. 96±26mg/dL, p=0.001). A large shift to the right in the distribution curve of non-HDL cholesterol among obese girls compared with non-obese was observed only when body fat percentage was used to discriminate between obese and non-obese. Body fat percentage was better than the indicators of weight status to identify children and adolescents with unfavorable lipid profile, mainly among girls. Copyright © 2017.

Weight misperception occurs when there is a discrepancy between one's actual and perceived weight status. Among adolescents with overweight/obesity, many believe that correcting weight misperception is imperative to inspire weight-related behavior change. However, past research has shown that adolescents with overweight/obesity who misperceive their weight status gain less weight over time compared to accurate perceivers. Therefore, our objective was to examine possible mechanisms underlying this relationship. Specifically, we examined the association between weight misperception and engagement in weight-related health behaviors among adolescents with overweight/obesity. Self-reported data from the 2015 National Youth Risk Behavior Survey was used in analyses restricted to participants with overweight/obesity (n = 4383). Using multivariate logistic models correcting for sex, race/ethnicity, and grade in school, we examined the cross-sectional associations between weight misperception and engagement in weight-related health behaviors, specifically related to dietary intake, physical activity, and sleep. Adolescents with overweight/obesity who misperceived their weight status were more likely to drink 100% fruit juice two or more times per day (OR = 1.53, 95% CI: 1.20, 1.94), eat vegetables two or more times per day (OR = 1.29, 95% CI: 1.07, 1.57), be physically active for 1 hour or more per day for at least 5 days in the week prior (OR = 1.40, 95% CI: 1.15, 1.72), be on a sports team in the last year (OR = 1.55, 95% CI: 1.21, 1.97), sleep an average of at least 8 hours per school night (OR = 1.40, 95% CI: 1.15, 1.72), and less likely to be trying to lose weight (OR = 0.17, 95% CI: 0.15, 0.20). Misperceivers were more likely to consume breakfast every morning in the week prior and to drink a sports drink at least once per day, though these results were not statistically significant. We observed no difference in fruit intake, soda intake

Full Text Available Weight perceptions and weight control behaviors have been documented with underweight and overweight adolescents, yet limited information is available on normal weight adolescents. This study investigates the prevalence of overweight misperceptions and weight control behaviors among normal weight adolescents in the U.S. by sociodemographic and geographic characteristics. We examined data from the 2003 Youth Risk Behavior Survey (YRBS. A total of 9,714 normal weight U.S. high school students were included in this study. Outcome measures included self-reported height and weight measurements, overweight misperceptions, and weight control behaviors. Weighted prevalence estimates and odds ratios were computed. There were 16.2% of normal weight students who perceived themselves as overweight. Females (25.3% were more likely to perceive themselves as overweight than males (6.7% (p < 0.05. Misperceptions of overweight were highest among white (18.3% and Hispanic students (15.2% and lowest among black students (5.8%. Females (16.8% outnumbered males (6.8% in practicing at least one unhealthy weight control behavior (use of diet pills, laxatives, and fasting in the past 30 days. The percentage of students who practiced at least one weight control behavior was similar by ethnicity. There were no significant differences in overweight misperception and weight control behaviors by grade level, geographic region, or metropolitan status. A significant portion of normal weight adolescents misperceive themselves as overweight and are engaging in unhealthy weight control behaviors. These data suggest that obesity prevention programs should address weight misperceptions and the harmful effects of unhealthy weight control methods even among normal weight adolescents.

Despite considerable efforts the prevalence of overweight and obesity in youth remains high. Poor motor skills have been associated with increased body weight but there is still limited information on the longitudinal association of these health parameters. This study examined the prospective association between motor skills and body weight in 10- to 14-year-old youth. Body weight, height and motor skills, assessed via the German motor test 16-18 (Deutscher Motorik Test, DMT6-18), were measured in 213 middle school students (57% male) every year over a 4‑year period. Club sports participation and migration status were assessed via a questionnaire. Besides an inverse cross-sectional association between body weight and motor skills, excess body weight was associated with impaired development of motor skills (p skills at baseline also reduced the odds of becoming overweight/obese during the observation period. These results were independent of club sports participation. There is a bidirectional, synergistic association between body weight and motor skills. Facilitating the development of motor skills in children and adolescents may therefore be a viable intervention strategy targeting weight management and physical activity in youth.

Full Text Available Purpose. To identify whether non-overweight students were different from their overweight or obese peers with respect to diet, suboptimal meal behaviours, and physical activity using a self-administered web-based survey. Methods. 4097 adolescents living in Alberta, Canada completed Web-SPAN (Web Survey of Physical Activity and Nutrition. Students were classified as overweight or obese, and differences were described in terms of nutrient intakes, physical activity, and meal behaviours. Results. Non-overweight students consumed significantly more carbohydrate and fibre, and significantly less fat and high calorie beverages, and had a higher frequency of consuming breakfast and snacks compared to overweight or obese students. Both non-overweight and overweight students were significantly more active than obese students. Conclusions. This research supports the need to target suboptimal behaviours such as high calorie beverage consumption, fat intake, breakfast skipping, and physical inactivity. School nutrition policies and mandatory physical education for all students may help to improve weight status in adolescents.

Full Text Available Abstract Background Adolescent obesity is prevalent in Pacific region ethnic groups (European, Melanesian and Polynesian living in both urban and rural areas. Although body perception is an important factor of weight gain or loss, little is known about the body self-perceptions of Pacific region adolescents. This study therefore evaluated adolescent perceptions of body weight according to ethnicity (European, Melanesian or Polynesian, socioeconomic status (low, intermediate or high and living area (rural or urban in New Caledonia. Methods Sociodemographic and anthropomorphic data from 737 adolescents (351 boys and 386 girls with ages ranging from 11 to 16 years were collected and analysed. The International Obesity Task Force (IOTF standards were used to define weight status as normal-weight, underweight or overweight/obese. Weight perception was assessed from detailed questionnaires, with adolescents rating their own weight with the following descriptors: ‘about the right weight’, ‘too heavy’, or ‘too light’. Results Results showed that only 8.5% of normal-weight adolescents (7% boys and 10% girls identifying themselves as ‘too heavy’. Normal-weight Melanesian adolescents were less likely than their European counterparts to assess themselves as too heavy (OR = 0.357. However, half the overweight/obese adolescents underestimated their weight status (53% boys and 48% girls. Weight misperception was associated with ethnicity, socioeconomic status and living area, with gender-specific differences. Conclusions The results of this study suggest that these sociodemographic factors should be taken into account when designing public health policies and health education school programmes in New Caledonia and, more broadly, the Pacific region.

Sexual minority girls (lesbian/bisexual) and girls with overweight/obesity experience high rates of discrimination and mental distress. This study explored whether BMI or perceived weight status might compound sexual minority girls' risk for harassment and mental distress. Data on female students from the national 2015 Youth Risk Behavior Survey (n = 7,006) were analyzed. Logistic regression was used to examine differences in bullying, harassment, and mental distress across sexual identity/BMI groups: heterosexual/normal-weight, heterosexual/overweight, sexual minority/normal-weight, and sexual minority/overweight. Procedures were repeated with four analogous groups created from sexual identity and perceived weight. Across sexual identity/BMI groups, being overweight increased heterosexual females' odds of being bullied or experiencing suicidal thoughts and behaviors. Regardless of weight status, sexual minority females had greater odds for each outcome than heterosexual females. Sexual minority females who perceived themselves as overweight had greater odds of suicidality than all other sexual minority/perceived weight groups. Double jeopardy may exist for sexual minority female students who perceive themselves as overweight. Professional development with school staff on how to create a positive climate for sexual minorities and those with overweight/obesity and addressing positive identity and body image within school-based suicide prevention efforts may be important to the well-being of adolescent girls. © 2017 The Obesity Society.

The purpose of this study was to determine the associations among evening snacking (food choices, portion sizes), afterschool-evening screen time, overall diet quality, and weight status. Participants consisted of 1008 young adolescents (secondary analyses, n = 651) from schools in Windsor-Essex, Ontario. The Web-based Food Behaviour Questionnaire, including a 24-h diet recall, was used to assess eating and screen time behaviours (television and video and computer games), as well as nutrient intake; height and weight for BMI were measured using a stadiometer. Results indicated that the majority of participants (62%) consumed an evening snack that contributed approximately 11% of their daily caloric intake. Evening snacking was associated with an overall good diet quality compared with that of non-evening snackers (p snack servings of vegetables and fruit (p snack food portion sizes (p snacking factors, participants with greater than 6 h of afterschool-evening screen time were less likely to have a good overall diet quality compared with those with less than 1 h of afterschool-evening screen time. Therefore, increased screen time, because it is associated with greater evening snack portion sizes and overall poor diet quality, is of great concern regarding young adolescents' evening behaviour.

Bariatric surgery is increasingly considered for the treatment of adolescents with severe obesity, but few prospective adolescent-specific studies examining the efficacy and safety of weight-loss surgery are available to support clinical decision making. We prospectively enrolled 242 adolescents undergoing weight-loss surgery at five U.S. centers. Patients undergoing Roux-en-Y gastric bypass (161 participants) or sleeve gastrectomy (67) were included in the analysis. Changes in body weight, coexisting conditions, cardiometabolic risk factors, and weight-related quality of life and postoperative complications were evaluated through 3 years after the procedure. The mean (±SD) baseline age of the participants was 17±1.6 years, and the mean body-mass index (the weight in kilograms divided by the square of the height in meters) was 53; 75% of the participants were female, and 72% were white. At 3 years after the procedure, the mean weight had decreased by 27% (95% confidence interval [CI], 25 to 29) in the total cohort, by 28% (95% CI, 25 to 30) among participants who underwent gastric bypass, and by 26% (95% CI, 22 to 30) among those who underwent sleeve gastrectomy. By 3 years after the procedure, remission of type 2 diabetes occurred in 95% (95% CI, 85 to 100) of participants who had had the condition at baseline, remission of abnormal kidney function occurred in 86% (95% CI, 72 to 100), remission of prediabetes in 76% (95% CI, 56 to 97), remission of elevated blood pressure in 74% (95% CI, 64 to 84), and remission of dyslipidemia in 66% (95% CI, 57 to 74). Weight-related quality of life also improved significantly. However, at 3 years after the bariatric procedure, hypoferritinemia was found in 57% (95% CI, 50 to 65) of the participants, and 13% (95% CI, 9 to 18) of the participants had undergone one or more additional intraabdominal procedures. In this multicenter, prospective study of bariatric surgery in adolescents, we found significant improvements in weight

The study applied 20 to 22 years of follow-up data on 712 Danish adolescents aged between 15 and 19 years at baseline. Self-reported height and weight, cannabis, cigarette and alcohol use, socioeconomic status (SES and physical activity levels were assessed in baseline surveys conducted in 1983 and 1985. The follow-up survey was conducted in 2005. In total 19.1% (n = 136 of adolescents reported having used/using cannabis. Weight gain between adolescence and midlife was not related to cannabis exposure during adolescence in either crude or adjusted models, and associations were not modified by baseline alcohol intake or smoking. However, cannabis use was significantly associated with cigarette smoking (p<0.001 and alcohol intake (p<0.001 and inversely associated with physical activity levels (p = 0.04. In conclusion, this study does not provide evidence of an association between adolescence cannabis use and weight change from adolescence to midlife.

Fast food restaurants have become widespread in both developed and developing countries due to nutritional and economic transitions. The frequency of fast food intake is relatively high among adolescents; however, fast food consumption is positively associated with total energy intake and obesity in adolescents. This study aimed to examine the perception of Jordanian adolescents towards fast foods relative to gender and obesity. A cross-sectional survey was conducted on 400 boys and 395 girls, aged 15-18 years. The adolescents completed a validated questionnaire to measure the perception of adolescents towards fast foods during the year 2013-2014. Weight and height were measured. Numbers who were non-overweight, overweight, and obese were calculated for each age and sex using the International Obesity Task Force (IOTF) standard. The majority of participants perceived foods which are eaten as sandwiches as fast foods. A significant difference between boy and girl adolescents was reported regarding perception of French fries ( p fast foods. Girls were significantly more enthusiastic than boys to consider cuscusi plate ( p foods ( p foods ( p foods ( p foods ( p fast foods. The difference between obese and non-obese regarding the perception of fast foods was only significant among boy participants. Western or non-Arab foods, food prepared fast and eaten fast in self-service outlets, and food rich in calories were significantly perceived as fast food by Jordanian adolescents ( p foods as fast foods or non-fast foods was significantly different between both genders as well as in obese and non-obese male Jordanian adolescents.

Weight-based teasing is common among youth, but little is known about its long-term impact on health outcomes. We aimed to 1) identify whether weight-based teasing in adolescence predicts adverse eating and weight-related outcomes 15years later; and 2) determine whether teasing source (peers or family) affects these outcomes. Data were collected from Project EAT-IV (Eating and Activity in Teens and Young Adults) (N=1830), a longitudinal cohort study that followed a diverse sample of adolescents from 1999 (baseline) to 2015 (follow-up). Weight-based teasing at baseline was examined as a predictor of weight status, binge eating, dieting, eating as a coping strategy, unhealthy weight control, and body image at 15-year follow-up. After adjusting for demographic covariates and baseline body mass index (BMI), weight-based teasing in adolescence predicted higher BMI and obesity 15years later. For women, these longitudinal associations occurred across peer and family-based teasing sources, but for men, only peer-based teasing predicted higher BMI. The same pattern emerged for adverse eating outcomes; weight-based teasing from peers and family during adolescence predicted binge eating, unhealthy weight control, eating to cope, poor body image, and recent dieting in women 15years later. For men, teasing had fewer longitudinal associations. Taken together, this study shows that weight-based teasing in adolescence predicts obesity and adverse eating behaviors well into adulthood, with differences across gender and teasing source. Findings underscore the importance of addressing weight-based teasing in educational and health initiatives, and including the family environment as a target of anti-bullying intervention, especially for girls.

Overvaluation of shape and weight is a key diagnostic feature of anorexia nervosa (AN); however, limited research has evaluated the clinical utility of differentiating between weight versus shape concerns. Understanding differences in these constructs may have important implications for AN treatment given the focus on weight regain. This study examined differences in treatment outcome between individuals whose primary concern was weight versus those whose primary concern was shape in a randomized controlled trial of treatment for adolescent AN. Data were drawn from a two-site randomized controlled trial that compared family-based treatment and adolescent focused therapy for AN. Chi-square tests and logistic regression analyses were conducted. Thirty percent of participants presented with primary weight concern (n = 36; defined as endorsing higher Eating Disorder Examination (EDE) Weight Concern than Shape Concern subscale scores); 60 % presented with primary shape concern (n = 72; defined as endorsing higher EDE Shape Concern than Weight Concern scores). There were no significant differences between the two groups in remission status at the end of treatment. Treatment did not moderate the effect of group status on achieving remission. Results suggest that treatment outcomes are comparable between adolescents who enter treatment for AN with greater weight concerns and those who enter treatment with greater shape concerns. Therefore, treatment need not be adjusted based on primary weight or primary shape concerns.

This paper aims to describe the prevalence of parent-adolescent conversations about eating, physical activity and weight across sociodemographic characteristics and to examine associations with adolescent BMI, dietary intake, physical activity and sedentary behaviors. Data from two linked epidemiological studies were used for cross-sectional analysis. Parents (n=3,424; 62% females) and adolescents (n=2,182; 53.2% girls) were socioeconomically and racially/ethnically diverse. Fathers reported more parent-adolescent conversations about healthful eating and physical activity with their sons and mothers reported more weight-focused conversations with their daughters. Parents of Hispanic/Latino and Asian/Hmong youth and parents from lower SES categories engaged in more conversations about weight and size. Adolescents whose mothers or fathers had weight-focused conversations with them had higher BMI percentiles. Adolescents who had two parents engaging in weight-related conversations had higher BMI percentiles. Healthcare providers may want to talk about the types of weight-related conversations parents are having with their adolescents and emphasize avoiding conversations about weight specifically.

Research is needed to confirm that public health recommendations for home/family food environments are equally relevant for diverse populations. This study examined ethnic/racial differences in the home/family environments of adolescents and associations with dietary intake and weight status. The sample included 2374 ethnically/racially diverse adolescents and their parents enrolled in coordinated studies, EAT 2010 (Eating and Activity in Teens) and Project F-EAT (Families and Eating and Activity in Teens), in the Minneapolis/St. Paul metropolitan area. Adolescents and parents completed surveys and adolescents completed anthropometric measurements in 2009-2010. Nearly all home/family environment variables (n=7 of 8 examined) were found to vary significantly across the ethnic/racial groups. Several of the home/family food environment variables were significantly associated with one or more adolescent outcome in expected directions. For example, parental modeling of healthy food choices was inversely associated with BMI z-score (p=0.03) and positively associated with fruit/vegetable consumption (peating was associated with lower intake of sugar-sweetened beverages only among youth representing the White, African American, Asian, and mixed/other ethnic/racial groups and was unrelated to intake among East African, Hispanic, and Native American youth. Food and nutrition professionals along with other providers of health programs and services for adolescents should encourage ethnically/racially diverse parents to follow existing recommendations to promote healthy eating such as modeling nutrient-dense food choices, but also recognize the need for cultural sensitivity in providing such guidance.

The purpose of this study was to examine the impact of age and weight status on adolescents' body dissatisfaction and its change over 20 months in a gender-comparing design. The influence of body image concern on eating concern was also investigated. In a prospective study, 675 male and female adolescents aged 12-16 were assessed using self-report questionnaires on weight, shape, muscularity, and eating concerns. Height and weight measurements were taken by trained personnel. Data were analyzed using structural equation modeling. Analyses of latent means revealed more pronounced weight/shape concern in females than males and more pronounced muscularity concern in males than females. Weight/shape concern increased in females over time, whereas muscularity concern remained stable in both genders. Baseline levels of weight/shape concern could be predicted by age and weight status in females and by weight status in males. The only predictor of change in weight/shape concern was weight status in males. Baseline levels of muscularity concern could be predicted by age in females and by weight status in males. Similar effects were found for changes in muscularity concern in both genders. Increases in weight/shape and muscularity concern were associated with more pronounced eating concern. The results confirm gender differences in distinctive facets of body image concern and its prediction. The relevance of increase in body image concern in adolescents is underlined by its association with eating concern in both genders. Further explanatory variables for change in body dissatisfaction should be examined in future studies. © 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2017; 50:139-147). © 2016 Wiley Periodicals, Inc.

To describe the meal patterns of Jena schoolchildren and their associations with children's weight status and parental characteristics. Cross-sectional study. Twenty schools in Jena (100,000 inhabitants), south-east Germany. A total of 2054 schoolchildren aged 7-14 years with information on BMI standard deviation score (BMI-SDS) and weight status (based on German reference values), of whom 1571 had additional information about their parents (parental education and employment status, weight status according to WHO guidelines) and meal patterns (school lunch participation rate, meal frequencies, breakfast consumption and frequency of family meals). Weight status of the children was associated with weight status, education and employment status of the parents. Meal patterns were strongly dependent on children's age and parental employment. As age increased, the frequency of meal consumption, participation rate in school lunches and the number of family meals decreased. Using linear regression analysis, a high inverse association between BMI-SDS and meal frequency was observed, in addition to relationships with parental weight status and paternal education. Age-specific prevention programmes should encourage greater meal frequency. The close involvement of parents is essential in any strategy for improving children's (families') diets.

Full Text Available OBJECTIVE: To assess the prevalence of low body weight/thinness, overweight and obesity in a representative sample of children and adolescents from a Brazilian region with low economic development. METHODS: A total of 982 girls and 986 boys, aged seven to 17 years old and assisted by Segundo Tempo Program, from Montes Claros, Minas Gerais, Brazil, were included in the study. Low body weight/thinness, overweight and obesity were defined based on body mass cut-off indexes recommended by the International Obesity Task Force. The prevalence of the nutritional status according to sex and age was compared by chi-square test. RESULTS: In girls, the frequency of low body weight/thinness, overweight and obesity was 4.1, 18.4 and 3.8%, respectively; in boys, these percentages were 6.3, 13.2 and 2.9%, respectively. The low body weight/thinness for girls raised from 2.7% (7-10 years old to 5.5% (15-17 years old; the body weight excess (overweight and obesity decreased from 30.1 to 16.2% for the same age groups. In boys, the corresponding trends were from 3.2 to 9.4% for low body weight/thinness, and from 23.4 to 9.2%, for body weight excess. CONCLUSIONS: The data indicate that, even in a region with low economic status, the body weight excess was the main problem associated with nutritional health. The high overweight and obesity prevalence rates indicate the need of public policies for promoting healthy feeding behaviors and physical activity.

Accurate assessment of nutritional status is a vital aspect of caring for individuals with anorexia nervosa (AN) and body mass index (BMI) is considered an appropriate and easy to use tool. Because of the intense fear of weight gain, some individuals may attempt to mislead the physician. Mid-upper arm circumference (MUAC) is a simple, objective method of assessing nutritional status. The setting is an eating disorders clinic in a tertiary paediatric hospital in Western Australia. The aim of this study is to evaluate how well MUAC correlates with BMI in adolescents with AN. Prospective observational study to evaluate nutritional status in adolescents with AN. Fifty-five adolescents aged 12-17 years with AN were assessed between January 1, 2004 and January 1, 2006. MUAC was highly correlated with BMI (r = 0.79, P or=20 cm rarely required hospitalisation (negative predictive value 93%). MUAC reflects nutritional status as defined by BMI in adolescents with AN. Lack of consistency between longitudinal measurements of BMI and MUAC should be viewed suspiciously and prompt a more detailed nutritional assessment.

The body mass index (BMI of 5254 adolescents was calculated based on self-reported weight and height measurements. Body weight status was determined by the age- and gender-specific International Obesity Task Force reference tables. By using participants of average weight as the reference group, the association between body weight status (underweight, overweight, and obesity and mental health indicators (depression, social phobia, insomnia, and self-esteem were examined by using multiple regression analysis. The possible moderating effects of sociodemographic characteristics on the association were also examined. After controlling for the effects of sociodemographic characteristics, both overweight (p < 0.05 and obese adolescents (p < 0.001 had a lower level of self-esteem than did those of average weight; however, no significant differences in depression, social phobia, or insomnia were found between those who were overweight/obese and those of average weight. No significant differences in the four mental health indicators were found between those who were underweight and those of average weight. Sociodemographic characteristics had no moderating effect on the association between body weight and mental health indicators. In conclusion, mental health and school professionals must take the association between overweight/obesity and self-esteem into consideration when approaching the issue of mental health among adolescents.

The aim or this study was to determine factors associated with body weight status among Iranian adolescents in the two Secondary Schools run by the Embassy in Kuala Lumpur. A self administered questionnaire was used to assess socio demographic characteristics, physical activity, and body image. Dietary intake was recorded through individual interviews with the researcher. The Physical Activity Questionnaire for children (PAQ-C) was used to evaluate levels of physical activity of the adolescents. One-third (32.2%) of respondents were of normal weight, 14.5% and 11.1% were overweight and obese respectively, while 18.6% and 23.6% were severe thinness and thinness respectively. While the distribution of obese respondents by gender was almost the same, overweight females (16.4%) exceeded overweight males (12.7%) and although more females were in the thinness category (24.7% compared to 22.7%), more males were severely thin (20.0%) compared to 17.1% of the females. Body weight status was significantly associated with age (p school to design intervention programs to improve the body weight status of their students.

Little is known about how interpersonal friend relationships are associated with obesity in young people, particularly with regard to how race/ethnicity, type of friendship, and sex affect the association between friends' and adolescents' weight status. This study examined associations in weight status among adolescents and their friends, exploring magnitudes of associations across friendship type, sex, and race/ethnicity. As part of EAT-2010 (Eating and Activity in Teens), friend nominations and anthropometrics were obtained from adolescents (n = 2099: 54% female; 80% nonwhite; mean age: 14.2 ± 1.9 years). Generalized estimating equation logistic regression models were used to test associations between adolescents' overweight/obese status and friends' (i.e., friend group, female friends, male friends, female best friends, and male best friends) overweight/obese status. Interactions by adolescent race/ethnicity were examined. The majority of significant associations were observed among white female adolescents' who had a 22-40% higher prevalence of overweight/obesity if their friends were overweight compared to white females whose friends were not overweight. In contrast, there were few significant differences for other adolescent female and male racial/ethnic groups for girls and boys. Results for friend groups and best friends were generally similar to one another. The association between friend and adolescent overweight/obese status depended on adolescents' sex, race/ethnicity, and friendship type. Given the similarities among friends, obesity interventions targeting youth, especially white females, should consider involving friends.

This study provides updated information regarding the prevalence and characteristics of weight stigma in popular adolescent television programming, using a sample of favorite shows named by diverse adolescents. Participants in a large, population-based study of Minnesota adolescents (N = 2,793, mean age = 14.4) listed their top three favorite television shows. A coding instrument was developed to analyze randomly selected episodes from the most popular 10 programs. Weight-stigmatizing incidents were compared across television show characteristics and characters' gender and weight status. Half (50%) of the 30 episodes analyzed contained at least one weight-stigmatizing incident. Both youth- and adult-targeted shows contained weight-stigmatizing comments, but the percent of these comments was much higher for youth-targeted (55.6%) than general audience-targeted shows (8.3%). Male characters were more likely than females to engage in (72.7% vs. 27.3%), and be the targets of, weight stigma (63.6% vs. 36.4%), and there was no difference in the amount of weight stigmatizing directed at average weight females compared to overweight females. Targets of these instances showed a negative response in only about one-third of cases, but audience laughter followed 40.9% of cases. The portrayal of weight stigmatization on popular television shows-including targeting women of average weight-sends signals to adolescents about the wide acceptability of this behavior and the expected response, which may be harmful. Prevention of weight stigmatization should take a multi-faceted approach and include the media. Future research should explore the impact that weight-related stigma in television content has on viewers. © 2014 Wiley Periodicals, Inc.

Dating violence is a major public health issue among youth. Overweight/obese adolescents experience peer victimization and discrimination and may be at increased risk of dating violence victimization. Furthermore, given the stigma associated with overweight/obesity, perceptions and misperceptions of overweight may be more important than actual weight status for dating violence victimization. This study examines the association of three weight indices (weight status, perceived weight, and weight perception accuracy) with psychological and physical dating violence victimization. The 2010 baseline survey of the 7-year NEXT Generation Health Study used a three-stage stratified clustered sampling design to select a nationally representative sample of U.S. 10th-grade students (n = 1,983). Participants who have had a boyfriend/girlfriend reported dating violence victimization and perceived weight. Weight status was computed from measured height/weight. Weight perception accuracy (accurate/underestimate/overestimate) was calculated by comparing weight status and perceived weight. Gender-stratified regressions examined the association of weight indices and dating violence victimization. Racial/ethnic differences were also examined. The association of weight indices with dating violence victimization significantly differed by gender. Overall, among boys, no associations were observed. Among girls, weight status was not associated with dating violence victimization, nor with number of dating violence victimization acts; however, perceived weight and weight perception accuracy were significantly associated with dating violence victimization, type of victimization, and number of victimization acts. Post hoc analyses revealed significant racial/ethnic differences. White girls who perceive themselves (accurately or not) to be overweight, and Hispanic girls who are overweight, may be at increased risk of dating violence victimization. These findings suggest a targeted approach to

In adolescents, there is limited evidence on the independent and additive effect of prepregnancy body mass index (BMI) and gestational weight gain on infant birth weight. Data also show that this effect may vary by race. We sought to examine the impact of maternal prepregnancy BMI and gestational weight gain on birth weight and risk of large for gestational age (LGA) in term newborns of minority adolescent mothers. This was a retrospective cohort study of 411 singleton live term infants born to mothers ≤ 18 years. Data were abstracted from electronic medical records. Gestational weight gain was related to infant birth weight (ρ = 0.36, P gain, gestational age and Hispanic ethnicity were independent predictors of birth weight, controlling for maternal age, BMI, parity, tobacco/drug use and preeclampsia. The probability of having an LGA infant increased with weight gain [adjusted odds ratio (aOR) 1.14, 95% confidence interval (CI) 1.07-1.21] but not with BMI. Mothers who gained weight in excess of 2009 Institute of Medicine (IOM) recommendations had a greater risk of having an LGA infant compared to those who gained within recommendations (aOR 5.7, 95% CI 1.6-19.5). Minority adolescents with greater gestational weight gain had infants with higher birth weight and greater risk of LGA; BMI was not associated with either outcome. Further studies are needed to examine the applicability of the 2009 BMI-specific IOM gestational weight gain recommendations to adolescents in minority populations.

Full Text Available OBJECTIVE: To compare body composition, hemodynamic parameters, health-related physical fitness, and health-related quality of life of adolescents with anthropometric diagnosis of overweight, obesity, and severe obesity.METHODS: 220 adolescents with excess body weight were enrolled. They were beginners in a intervention program that included patients based on age, availability, presence of excess body weight, place of residence, and agreement to participate in the study. This study collected anthropometric and hemodynamic variables, health-related physical fitness, and health-related quality of life of the adolescents. To compare the three groups according to nutritional status, parametric and non-parametric tests were applied. Significance level was set at p0.05. Body weight, body mass index, waist and hip circumference, and systolic blood pressure increased as degree of excess weightincreased (p<0.05. Dyastolic blood pressure of the severe obesity group was higher than the other groups (p<0.05. There was an association between the degree of excess weight and the prevalence of altered blood pressure (overweight: 12.1%; obesity: 28.1%; severe obesity: 45.5%; p<0.001. The results were similar when genders were analyzed separately.CONCLUSION: Results suggest that overweight adolescents presented similar results compared to obese and severely obese adolescents in most of the parameters analyzed.

-perception and nutritional status based on objective measurements of weight, height, and skin folds in adolescents, and to evaluate factors associated with disagreement between these measures. METHODS: The sample included the 1993 birth cohort from the city of Pelotas, Brazil, who were interviewed at home in 2004 and 2005. The study outcome resulted from the comparison between nutritional status and the weight self-perception of adolescents, and was divided into three categories: underestimation, agreement, and overestimation. The explanatory variables were sex, skin color, accumulated goods index, physical activity, eating habits, discrimination, dieting, feeling of well-being, and opinion of the adolescent concerning the perception of his/her parents regarding the adolescent's weight. Multivariate logistic regression was used for statistical analysis. RESULTS: A total of 4 452 interviews were conducted (87.5% of original cohort. Mean age was 11 years. The analysis of nutritional status revealed that 7.1% were underweight, 69.8% normal weight, 11.6% overweight, and 11.6% obese. The analysis of self-perceived weight revealed that 19% saw themselves as thin or very thin, 56% believed their weight was normal, and 25% saw themselves as fat or very fat. Global agreement between weight self-perception and nutritional status was 65% (kappa = 0.36. Weight underestimation occurred in 24.9% of boys vs. 20.3% of girls. Overestimation occurred in 15.8% of girls vs. 8.5% of boys. CONCLUSIONS: Girls tended to overestimate their weight, and boys, to underestimate it. There was a strong association between the opinion of adolescents concerning their parents' view of the adolescent's body and self-perceived weight.

Current research indicates that specific parenting styles are associated with adolescent overweight, dietary intake, and physical activity; but most of the research has been cross-sectional, making it difficult to determine the temporal order of these associations. The current study adds to the previous research by examining 5-year longitudinal associations between parenting style and adolescent weight and weight-related behaviors. Data from Project EAT, a population-based study with adolescents from diverse ethnic and socioeconomic backgrounds, were used. Adolescents (N = 2,516) from 31 Minnesota schools completed in-class assessments in 1999 (Time 1) and mailed surveys in 2004 (Time 2). Multiple linear regression models were used to predict mean levels of adolescent outcomes at Time 2 from parenting style at Time 1. Time 1 maternal authoritative parenting style predicted lower body mass index in adolescent sons and daughters at Time 2. Time 1 paternal permissive parenting style predicted more fruits and vegetables intake in daughters at Time 2. Significant associations were not found between parenting style and adolescent physical activity. Findings suggest that authoritative parenting style may play a protective role related to adolescent overweight and that the dimension of warmth and/or caring in the parent-adolescent relationship may be important in relation to female adolescent healthy dietary intake. Further exploration of opposite sex parent-adolescent dyad patterns related to parenting style and adolescent weight and weight-related behaviors is warranted.

To compare overweight and obese adolescents with accurate and inaccurate self-reported weight perception across a range of behaviours and measures of psychological well-being. This study uses a cross-sectional survey of grade 7-12 high school students in New South Wales, Australia, conducted in 2008 (n= 7553). Overweight and obese students based on body mass index were classified as accurate perceivers (weight perception was 'too fat') or inaccurate perceivers (weight perception was 'about right'). Nearly a third of adolescents had incongruity between self-perceived body weight status and body mass index-determined weight category. Compared with boys, girls were less likely to underestimate their body weight (odds ratio: 0.26; 95% confidence interval: 0.25, 0.27) and more likely to overestimate their body weight (odds ratio: 3.4; 95% confidence interval: 3.3, 3.5). Accurate body weight perception was higher in obese adolescents compared with overweight adolescents (69.5% vs. 44.0%). Compared with mis-perceivers, accurate overweight and obese perceivers had significantly higher odds of trying to lose weight and being more physically active; however, they showed a combination of unhealthy and healthy behaviours (i.e. dietary patterns and sedentary activities). Accurate weight perception among overweight and obese adolescents was associated with increased odds of feeling sad or depressed in the past 6 months. Further research on social, familial and psychological factors that predict or mediate healthy and unhealthy weight-related behaviours among adolescents by accuracy of weight perception is needed. Accurate weight perception should be considered in counselling and behavioural interventions. © 2012 The Authors.

To assess the relationship between number of meals eaten and weight status, and to assess potential confounders of this relationship. A total of 2870 (participation rate: 85%) 9th and 10th graders (mean age: 15.5 years) at 33 schools completed questionnaires in May 2005. Number of meals was measured with questions asking whether they ate breakfast, lunch, dinner, and supper the day before, giving a scale ranging from zero to four meals/day. Data on gender, height, weight, education plans, intake of fruits and vegetables, consumption of unhealthy snacks, TV/computer time, physical activity level, and dieting were also collected. The proportions of overweight adolescents related to the number of meals eaten were: 10% (0-1 meals, n = 107), 18% (2 meals, n = 399), 14% (3 meals, n = 925), and 10% (4 meals, n = 1402), p ≤ 0.001. Low education plans, high TV/computer time, low physical activity level, and dieting were all positively associated with both being overweight and not having four meals. Being a boy was positively associated with being overweight but negatively associated with not having four meals. High intake of unhealthy snacks was negatively associated with being overweight, but positively associated with not having four meals. In a logistic regression analysis, adjusting for all variables mentioned, odds ratio for being overweight were 0.8 (95% CI 0.3-1.9), 1.8 (95% CI 1.2-2.7) and 1.6 (95% CI 1.2-2.3), respectively, for eating one or zero, two, and three meals compared to four meals. Eating four meals/day was significantly negatively related to being overweight, also when controlling for potential confounding factors.

Studies that link adolescence pregnancies, nutritional status, and birth outcomes in Tanzania are scarce. We examined the nutritional status and birth outcomes of pregnant adolescent girls from rural and urban areas of three regions in Tanzania. The study was carried out in the regions of Dar es Salaam (Chamazi and Gezaulole dispensaries and Round Table Maternity Home), Coast (Tumbi Regional Hospital and Mlandizi Health Center), and Morogoro (Regional Hospital, Uhuru Clinic, and Mlali Health Center). One hundred eighty pregnant adolescent girls ages 15 to 19 y were recruited and interviewed, and their nutritional status measurements were taken at the seven health facilities. Information concerning date of birth, marital status, educational status, sex education, and income status was collected with a structured questionnaire. Height, weight, and mid-upper arm circumference were measured according to standard techniques. Hemoglobin concentration was measured with a hemoglobinometer and the HemoCue technique. Nutritional status was assessed by body mass index, and hemoglobin concentration was determined by cutoff points of the World Health Organization. Suitable statistical analysis was done with SPSS 9.0. Weekly weight gain during pregnancy was measured in 123 subjects who kept their appointments and reported back after 2 wk. Fifty-seven subjects did not keep their appointments and were lost to follow-up. Records of infants' birth weights and mode of delivery were obtained from 50 subjects who delivered at the study sites. The height of about 54% of the subjects was shorter than 151 cm, suggestive of short maternal height. Severe wasting was observed in 27% of subjects. Mean weekly weight gain during pregnancy was 317 +/-110 g (-500 to 500 g). No significant differences were observed between rural and urban settings. Mean infant birth weight was 2600 +/- 480 g. About 48% of infants had low birth weight (hemoglobin concentration below 7 g/dL was observed in 5% of

To evaluate the perception of parents or caregivers on the health-related quality of life (HRQOL) of children/adolescents with overweight/obesity and possible factors associated with this perception. This was a cross-sectional study involving 297 caregivers of children and adolescents with normal weight (n=170) and with overweight/obesity (n=127), from public and private schools in the study municipality. HRQOL scores obtained through the Child Health Questionnaire - Parent Form 50 (CHQ-PF50) were compared according to the nutritional status and gender of the children/adolescents. Multiple regression analysis was used to determine the predictive value of studied variables for the variation in HRQOL scores. Parents of children/adolescents with overweight/obesity attributed lower HRQOL scores to their children in the following domains: physical functioning (pnutritional status (β=-0.18; p≤0.01); emotional impact on parents, impact on parents' time (β=0.31; pchildren/adolescents with overweight/obesity was observed in the physical and psychosocial aspects. The nutritional status was the variable with the greatest contribution for the assessment the self-esteem of children and adolescents in this study.

Childhood obesity and school bullying are pervasive public health issues and known to co-occur in adolescents. However, the association between underweight or thinness and chronic bullying victimization is unclear. The current study examined whether chronic bullying victimization is associated with weight status and body self-image. A school-based, cross-sectional study in 39 North American and European countries and regions was conducted. A total of 213,595 adolescents aged 11, 13, and 15 years were surveyed in 2009/10. Chronic bullying victimization was identified using the Revised Olweus Bully/Victim Questionnaire. Weight status was determined using self-reported height and weight and the body mass index (BMI), and body self-image was based on perceived weight. We tested associations between underweight and bullying victimization using three-level logistic regression models. Of the 213,595 adolescents investigated, 11.28% adolescents reported chronic bullying victimization, 14.80% were classified as overweight/obese according to age- and sex-specific BMI criteria, 12.97% were underweight, and 28.36% considered themselves a little bit fat or too fat, 14.57% were too thin. Bullying victimization was less common in older adolescent boys and girls. Weight status was associated with chronic bullying victimization (adjusted OR underweight = 1.10, 95% CI = 1.05-1.16, p = 0.002; adjusted OR overweight = 1.40, 95% CI = 1.32-1.49, p self-image also related to chronic bullying victimization (adjusted OR too thin = 1.42, 95% CI = 1.36-1.49, p self-rated overweight are associated with chronic bullying victimization. Both overweight and underweight children are at risk of being chronically bullied.

To investigate the prevalence and risk factors for disordered weight control behaviors (DWCB) in South Korean adolescents at multiple levels, including individual, family, school, and geographic area. We drew participants from the 11th Korea Youth Risk Behavior Web-based Survey, conducted in 2015, with 65,529 adolescents (31,687 girls, 33,842 boys) aged 12-18 years. DWCB was defined as engaging in any of the following behaviors for weight control over the past month: fasting, one-food diet (eating only one food over an extended period of time for weight control), vomiting, and taking laxatives/diuretics/unprescribed diet pills. Sex-stratified four-level multilevel logistic models examined potential predictors of DWCB, including age, body-mass index, puberty, perceived household economic status, parental education, living structure, school type and sex-composition, percentage of students participating in school nutrition programs, and urbanicity. Overall, 6.2% of Korean adolescents (8.9% of girls, 3.7% of boys) exhibited any DWCB. We found significant between-school variation among girls and boys and between-classroom variation among girls. Older age, overweight/obesity, pubertal maturity, high household economic status (vs. mid-range economic status), and vocational schooling (vs. general) were positively associated with DWCB among girls and boys. Low household economic status (vs. mid-range economic status), higher parental education, and coeducational schooling (vs. single-sex) were positively associated with DWCB among girls only. The findings suggest that DWCB are prevalent among Korean adolescents across age, sex, and socioeconomic status. Social contextual factors including school and familial environmental factors, as well as individual characteristics, should be considered when developing effective prevention strategies. © 2018 Wiley Periodicals, Inc.

Research to date in young children and adults shows a strong, inverse relationship between sleep duration and risk for overweight and obesity. Fewer studies examining this relationship have been conducted in adolescents. The purpose of the article is to describe the relationship between sleep and weight in a population of adolescents, controlling for demographics, energy intake, energy expenditure, and depression. This is a cross-sectional study of 723 adolescents participating in population-based studies of the etiologic factors related to obesity. We examined the relationship between three weight-related dependent variables obtained through a clinical assessment and three sleep variables obtained through self-report. Average caloric intake from dietary recalls, average activity counts based on accelerometers, and depression were included as covariates and the analysis was stratified by gender and grade level. Our results show that the relationship between sleep duration and BMI is evident in middle-school boys (β = -0.32, s.e. = 0.06: P high-school students. Differences in sleep patterns have little association with weight in males, but in high-school girls, waking up late on weekends as compared to weekdays is associated with lower body fat (β = -0.80, s.e. = 0.40: P = 0.05) and a healthy weight status (β = -0.28, s.e. = 0.14: P = 0.05). This study adds to the evidence that, particularly for middle-school boys and girls, inadequate sleep is a risk factor for early adolescent obesity. Future research needs to examine the relationship longitudinally and to study potential mediators of the relationship.

Pediatric obesity has become a global public health problem. Data on the lifestyle behaviors, dietary habits, and familial factors of overweight and obese children and adolescents are limited. The present study aims to compare health-related factors among normal-weight, overweight, and obese Chinese children and adolescents. We conducted a cross-sectional study consisted of 4262 children and adolescents aged 5-18 years old from rural areas of the northeast China. Anthropometric measurements and self-reported information on health-related variables, such as physical activities, sleep duration, dietary habits, family income, and recognition of weight status from the views of both children and parents, were collected by trained personnel. The prevalence rates of overweight and obesity were 15.3 and 6.4%, respectively. Compared to girls, boys were more commonly overweight (17.5% vs. 12.9%) and obese (9.5% vs. 3.1%). Approximately half of the parents with an overweight or obese child reported that they failed to recognize their child's excess weight status, and 65% of patients with an overweight child reported that they would not take measures to decrease their child's body weight. Obese children and adolescents were more likely to be nonsnackers [odds ratio (OR): 1.348; 95% confidence interval (CI): 1.039-1.748] and to have a family income of 2000 CNY or more per month (OR: 1.442; 95% CI: 1.045-1.99) and less likely to sleep longer (≥7.5 h) (OR: 0.475; 95% CI: 0.31-0.728) than the normal-weight participants. Our study revealed a high prevalence of overweight and obesity in a large Chinese pediatric population. Differences in sleep duration, snacking, family income, and parental recognition of children's weight status among participants in different weight categories were observed, which should be considered when planning prevention and treatment programs for pediatric obesity.
Full Text Available Abstract Background Obesity is emerging as a public health problem among adolescents in India. The aim of this study was to describe specific weight-related concerns among school-going youth in Delhi, India and to assess the prevalence of weight control behaviors, including healthy and unhealthy ones. Differences by weight status, gender, grade level, and school-type (a proxy for SES in this setting are considered. Methods This study is cross-sectional by design. A sample of eighth and tenth graders (n = 1818 enrolled in Private (middle-high SES and Government (low SES schools (n = 8 in Delhi, India participated. All students' height and weight were measured. Students participated in a survey of weight-related concerns and weight-control behaviors, as well. Mixed-effects regression models were used to test for differences in weight-related concerns and weight-control behaviors across key factors of interest (i.e., weight status, gender, grade level, and SES. Results The combined prevalence of obesity and overweight was 16.6%, overall. Controlling one's weight was important to overweight and non-overweight youth, alike (94.2% v. 84.8%, p p Conclusions Interventions to promote healthy weight control should be pertinent to and well-received by school-going youth in India. Healthy weight control practices need to be explicitly encouraged and unhealthy practices reduced. Future interventions should address issues specific to body image, too, as body dissatisfaction was not uncommon among youth.

While the trajectory of self-esteem from adolescence to adulthood varies from person to person, little research has examined how differences in early developmental processes might affect these pathways. This study examined how early motor skill development interacted with preterm birth status to predict self-esteem from adolescence through the early 30s. We addressed this using the oldest known, prospectively followed cohort of extremely low birth weight (self-report, and self-esteem was reported during three follow-up periods (age 12-16, age 22-26, and age 29-36). We found that birth weight status moderated the association between early motor skills and self-esteem. Stable over three decades, the self-esteem of normal birth weight participants was sensitive to early motor skills such that those with poorer motor functioning manifested lower self-esteem, while those with better motor skills manifested higher self-esteem. Conversely, differences in motor skill development did not affect the self-esteem from adolescence to adulthood in individuals born at extremely low birth weight. Early motor skill development may exert differential effects on self-esteem, depending on whether one is born at term or prematurely.

A disputed social status among peers puts children and adolescents at risk for developing a wide range of problems, such as being bullied. However, there is a lack of knowledge about which early predictors could be used to identify (young) adolescents at risk for a disputed social status. The aim of this study was to assess whether preventive child health care (PCH) findings on early childhood predict neglected and rejected status in early adolescence in a large longitudinal community-based sample. Data came from 898 participants who participated in TRAILS, a longitudinal study. Information on early childhood factors was extracted from the charts of routine PCH visits registered between infancy and age of 4 years. To assess social status, peer nominations were used at age of 10-12 years. Multinomial logistic regression showed that children who had a low birth weight, motor problems, and sleep problems; children of parents with a low educational level (odds ratios [ORs] between 1.71 and 2.90); and those with fewer attention hyperactivity problems (ORs = .43) were more likely to have a neglected status in early adolescence. Boys, children of parents with a low educational level, and children with early externalizing problems were more likely to have a rejected status in early adolescence (ORs between 1.69 and 2.56). PCH findings on early childhood-on motor and social development-are predictive of a neglected and a rejected status in early adolescence. PCH is a good setting to monitor risk factors that predict the social status of young adolescents. Copyright © 2012 Society for Adolescent Health and Medicine. Published by Elsevier Inc.

Married individuals often have higher body weights than unmarried individuals, but it is unclear how marital roles affect body weight-related perceptions, desires, and behaviors. This study analyzed cross-sectional data for 4,089 adult men and 3,989 adult women using multinomial logistic regression to examine associations between marital status, perceived body weight, desired body weight, and weight management approach. Controlling for demographics and current weight, married or cohabiting women and divorced or separated women more often perceived themselves as overweight and desired to weigh less than women who had never married. Marital status was unrelated to men's weight perception and desired weight change. Marital status was also generally unrelated to weight management approach, except that divorced or separated women were more likely to have intentionally lost weight within the past year compared to never married women. Additionally, never married men were more likely to be attempting to prevent weight gain than married or cohabiting men and widowed men. Overall, married and formerly married women more often perceived themselves as overweight and desired a lower weight. Men's marital status was generally unassociated with weight-related perceptions, desires, and behaviors. Women's but not men's marital roles appear to influence their perceived and desired weight, suggesting that weight management interventions should be sensitive to both marital status and gender differences. © 2013 Elsevier Ltd.

Research has shown that adolescents who frequently share evening meals with their families experience more positive health outcomes, including diets of higher nutritional quality. However, little is known about families eating together at breakfast. This study examined sociodemographic differences in family meal frequencies in a population-based adolescent sample. In addition, this study examined associations of family breakfast meal frequency with dietary quality and weight status. Cross-sectional data from EAT 2010 (Eating and Activity in Teens) included anthropometric assessments and classroom-administered surveys completed in 2009-2010. Participants included 2,793 middle and high school students (53.2% girls, mean age=14.4 years) from Minneapolis/St Paul, MN, public schools. Usual dietary intake was self-reported on a food frequency questionnaire. Height and weight were measured. Regression models adjusted for sociodemographic characteristics, family dinner frequency, family functioning, and family cohesion were used to examine associations of family breakfast frequency with dietary quality and weight status. On average, adolescents reported having family breakfast meals 1.5 times (standard deviation=2.1) and family dinner meals 4.1 times (standard deviation=2.6) in the past week. There were racial/ethnic differences in family breakfast frequency, with the highest frequencies reported by adolescents of black, Hispanic, Native American, and mixed race/ethnicity. Family breakfast frequency was also positively associated with male sex, younger age, and living in a two-parent household. Family breakfast frequency was associated with several markers of better diet quality (such as higher intake of fruit, whole grains, and fiber) and lower risk for overweight/obesity. For example, adolescents who reported seven family breakfasts in the past week consumed an average of 0.37 additional daily fruit servings compared with adolescents who never had a family breakfast meal

The link between obesity and self-esteem among minority youth has received minimal empirical evaluation. This study aims to describe the magnitude of risk that body mass index, household income, and transitional age have on global self-esteem levels among African-American adolescents. These analyses were conducted on cross-sectional data obtained from 264 urban-dwelling African-American females between 14 and 18 years of age. Survey data on global self-esteem levels, transitory age, and socioeconomic levels were collected using self-administered questionnaires. Measured height and weight values were used to calculate and categorize weight status according to body mass index. Logistic regression models examined the probability of reporting less than average levels of global self-esteem. Adolescent African-American females residing in low-income households were 10 times more likely to report lower global self-esteem scores than those individuals from more affluent households (95% CI: 1.94, 60.19, p self-esteem among participants in this study. Household income appears to be the greatest predictor of global self-esteem levels. Further research in this area is needed to fully elucidate precursors for psychological health vulnerability and facilitate intervention development.

The association between directly observed mother-adolescent weight-related communication quality and adolescent percent overweight within the context of an adolescent weight control study was examined. As part of a larger study examining the impact of a behavioral weight control intervention that included attention to parent-adolescent communication (Standard Behavioral Treatment + Enhanced Parenting, SBT + EP) compared with an efficacious Standard Behavioral Treatment (SBT), 38 mother-adolescent dyads participated in a weight-related videotaped discussion. Discussions were taped and collected pre- and postintervention. No significant differences emerged in the quality of mother-adolescent communication between SBT (n = 19) and SBT + EP (n = 19) participants, nor was baseline mother-adolescent communication quality associated with adolescents' weight loss in either condition. However, a decline in communication quality was associated with better outcomes for adolescents participating in the SBT group. This study provides preliminary evidence that a change in mother-adolescent communication is associated with successful weight loss among adolescents. © The Author 2014.

Inadequate physical activity and obesity during adolescence are areas of public health concern. Questions exist about the role of neighborhoods in the etiology of these problems. This research addressed the relationships of perceived and objective reports of neighborhood crime to adolescent physical activity, screen media use, and body mass index (BMI). Socioeconomically and racially/ethnically diverse adolescents (N = 2,455, 53.4% female) from 20 urban, public middle and high schools in Minneapolis/St. Paul, Minnesota responded to a classroom survey in the Eating and Activity in Teens 2010 study. BMI was measured by research staff. Participants' mean age was 14.6 (standard deviation = 2.0); 82.7% represented racial/ethnic groups other than non-Hispanic white. Linear regressions examined associations between crime perceived by adolescents and crime reported to police and the outcomes of interest (BMI z-scores, physical activity, and screen time). Models were stratified by gender and adjusted for age, race/ethnicity, socioeconomic status, and school. BMI was positively associated with perceived crime among girls and boys and with reported crime in girls. For girls, there was an association between higher perceived crime and increased screen time; for boys, between higher reported property crime and reduced physical activity. Perceived crime was associated with reported crime, both property and personal, in both genders. Few prior studies of adolescents have studied the association between both perceived and reported crime and BMI. Community-based programs for youth should consider addressing adolescents' safety concerns along with other perceived barriers to physical activity. Interventions targeting actual crime rates are also important. Copyright © 2015 Society for Adolescent Health and Medicine. Published by Elsevier Inc. All rights reserved.

To examine the association between gestational weight gain (GWG) and interpregnancy weight change (IPWC) in adolescent mothers (younger than 20 years), and to determine if this association differs from adult women (aged 20-35 years). Retrospective cohort study. We included 3055 adolescents and 17,090 adult women with singleton pregnancies recorded in the Nova Scotia Atlee Perinatal Database with a subsequent pregnancy occurring between 2003 and 2014. GWG in the first pregnancy was categorized as below, within, or above the current Institute of Medicine recommendations. IPWC was defined as the difference between the prepregnancy weights of the 2 pregnancies. Analyses were adjusted for parity, body mass index in the first pregnancy, and time between pregnancies. Relative to adolescents with GWG within the recommendations, those who gained below had a 2.7 kg (95% confidence interval [CI], 1.4-3.9) lower mean IPWC whereas those who gained above had a 4.2 kg (95% CI, 3.3-5.1) higher mean IPWC. Smaller differences in IPWC between GWG categories were observed in adult women; relative to those with GWG within the recommendations, adults who gained below had a 1.3 kg (95% CI, 0.9-1.7) lower mean IPWC and those who gained above had a 2.9 kg (95% CI, 2.6-3.2) higher mean IPWC. Mean IPWC differed across GWG categories and the differences were greater in adolescents than in adult women. This difference should be considered when assessing whether specific GWG recommendations are needed for adolescents. Copyright © 2017 North American Society for Pediatric and Adolescent Gynecology.

African American adolescents experience higher rates of obesity and have an increased risk of obesity-related diseases than do White American adolescents. Despite culturally sensitive obesity preventive interventions, obesity rates are increasing within the African American adolescent population. Current obesity interventions do not usually address the heterogeneity (e.g., socioeconomic status [SES], gender, and residential status differences) within the African American adolescent community that can affect the efficacy of these interventions. To examine the gender, SES, and residential status differences related to obesity and weight behaviors in African American adolescents. A descriptive correlational study was conducted with 15- to 17-year-old African American adolescents (n = 145) from community clinics, youth organizations, churches, and social networks in metropolitan and inner-city Detroit. Data were collected through use of survey methods and analyzed with use of descriptive statistics, independent sample t tests, and multiple regression equations. Female adolescents consumed foods higher in fat and calories (t = -2.36, p = .019) and had more body fat (t = -9.37, p = .000) than did males. Adolescents of lower SES consumed food higher in fat and calories (t = -2.23, p = .027) and had higher body mass (t = -2.57, p = .011) than did adolescents of higher SES. Inner-city African American adolescents had higher levels of physical activity (t = -2.39, p = .018) and higher body mass (t = 2.24, p = .027) than did suburban African American adolescent counterparts. Gender, SES, and residential status were statistically significant predictors of eating behaviors, physical activity, body mass index, and body fat. The initial findings from the study will assist in better understanding the obesity epidemic that affects African American adolescents in disparate proportions. Further examination of the study variables is essential to serve as a basis for

Over 30% of youth and adolescents have overweight or obesity, and health care providers are increasingly discussing weight-based health with these patients. Stigmatizing language in provider-patient communication about obesity is well documented and could be particularly detrimental to youth and adolescents. Although some research has examined preferences for weight-based terminology among adults, no studies have addressed these issues in youth populations. This study represents a preliminary and systematic investigation of weight-based language preferences among adolescents with overweight and obesity enrolled in a summer weight loss camp. Participants (N=50) indicated preferences for weight-based language and emotional responses to words that their family members used in reference to their body weight. Weight neutral terminology ('weight', 'body mass index') were most preferred, although some differences in word preferences emerged by the participants' gender. Boys preferred having their weight described as 'overweight' and 'heavy', while girls preferred the word 'curvy'. A large proportion of participants, particularly girls, reported experiencing sadness, shame, and embarrassment if parents used certain words to describe their body weight, which highlights the importance of considering the emotional impact of weight-based terminology. Providers may consider asking youth and adolescents for their preferences when discussing weight-based health.

Dieting and unhealthy weight control behaviors are common among adolescents and questions exist regarding their long-term effect on weight status. To examine 10-year longitudinal associations between dieting and unhealthy weight control behaviors and changes in body mass index (BMI) from adolescence to young adulthood. A diverse population-based sample of middle school and high school adolescents participating in Project EAT (Eating and Activity in Teens and Young Adults) was followed up for 10 years. Participants (N = 1,902) completed surveys in 1998-1999 (Project EAT-I), 2003-2004 (Project EAT-II), and 2008-2009 (Project EAT-III). Dieting and unhealthy weight control behaviors at Time 1 and Time 2 were used to predict 10-year changes in BMI at Time 3, adjusting for sociodemographic characteristics and Time 1 BMI. Dieting and unhealthy weight control behaviors at both Time 1 and Time 2 predicted greater BMI increases at Time 3 in males and females, as compared with no use of these behaviors. For example, females using unhealthy weight control behaviors at both Time 1 and Time 2 increased their BMI by 4.63 units as compared with 2.29 units in females not using these behaviors (p meals and reporting eating very little (females and males), use of food substitutes (males), and use of diet pills (females). Findings clearly indicate that dieting and unhealthy weight control behaviors, as reported by adolescents, predict significant weight gain over time.

The purpose of the present paper was to assess dietary energy reporting as a function of sex and weight status among Ontario and Alberta adolescents, using the ratio of energy intake (EI) to estimated BMR (BMRest). Data were collected using the FBQ, a validated web-based dietary assessment tool (including a 24 h dietary recall, FFQ, and food and physical activity behavioural questions). BMI was calculated from self-reported height and weight and participants were classified as normal weight, overweight or obese. BMR was calculated using the WHO equations (based on weight). Reporting status was identified using the ratio EI:BMRest. Data were collected in public, Catholic and private schools in Ontario and Alberta, Canada. A total of 1917 (n 876 male and n 1041 female) students (n 934 grade 9 and n 984 grade 10) participated. The mean EI:BMRest ratio across all participants was 1.4 (sd 0.6), providing evidence of under-reporting for the total sample. Females under-reported more than males (t = 6.27, P < 0.001), and under-reporting increased with increasing weight status for both males (F = 33.21, P < 0.001) and females (F = 14.28, P < 0.001). After removing those who reported eating less to lose weight, the EI:BMRest was 1.56 (sd 0.6) for males and 1.4 (sd 0.6) for females. The present study highlights methodological challenges associated with self-reported dietary data. Systematic differences in under-reporting of dietary intake by gender and weight status were observed using a web-based survey, similar to observations made using paper-based 24 h recalls and dietitian interviews.
Full Text Available Background Adolescents’ perception of their weight is a strong factor in shaping dietary habits and weight control and management. Among non-overweight and overweight adolescents, both overestimation and underestimation of weight status are associated with harmful effects. This study aimed to examine the relationship between perceived weight and attitude toward eating disorders among adolescent girls living in Karaj, Iran. Materials and Methods Involving a two-stage random sampling, this cross-sectional study was conducted on a total of 537 high school girls 14-18 years of age living in Karaj. The Eating Attitudes Test (EAT-26 was employed to screen for attitude toward eating disorders. Also, anthropometric measurements (weight and height, perceived and the ideal weights of the participants were assessed. Results The average age of girls participating in the study was 16.12±1.20. According to the results, 70% of girls had normal body mass index. It was found that the ideal weight of 55% of the girls in the normal body mass index group fell under the lower than normal boundary. Moreover, the prevalence of eating disorders was estimated to be 23.6%. The attitude toward eating disorder was significantly correlated with body mass index of participants and their self-concept (P

The purpose of this study was to examine secular changes in growth and nutritional status of Mozambican children and adolescents between 1992, 1999 and 2012. 3374 subjects (1600 boys, 1774 girls), distributed across the three time points (523 subjects in 1992; 1565 in 1999; and 1286 in 2012), were studied. Height and weight were measured, BMI was computed, and WHO cut-points were used to define nutritional status. ANCOVA models were used to compare height, weight and BMI across study years; chi-square was used to determine differences in the nutritional status prevalence across the years. Significant differences for boys were found for height and weight (p2012), and those from 2012 had the highest BMI (1999growth and nutritional status were observed among Mozambican youth from 1992 to 2012, which are associated with economic, social and cultural transitional processes, expressing a dual burden in this population, with reduction in malnourished youth in association with an increase in the prevalence of overweight and obesity.

To examine the association between observer ratings of physical attractiveness and weight preoccupation for female adolescents, and to explore any ethnic differences between Caucasian, African-American, and Hispanic females. Normal-weight female adolescents who had participated in the National Longitudinal Study of Adolescent Health in-home Wave II survey were included (n = 4,324). Physical attractiveness ratings were made in vivo by interviewers. Using logistic regression models stratified by ethnicity, the associations between observer-rated attractiveness and weight preoccupation were examined after controlling for demographics, measured body mass index (BMI) and psychosocial factors. Caucasian female adolescents perceived as being more attractive reported significantly greater weight preoccupation compared with those rated as being less attractive. Observed attractiveness did not relate to weight preoccupation among African-American or Hispanic youth when controlling for other factors. For Caucasian female adolescents, being perceived by others as more attractive may be a risk factor for disordered eating.

Information regarding associations between types of away-from-home family meal sources and obesity and other chronic diseases could help guide dietitians. The present study describes the purchase frequency of away-from-home food sources for family dinner (fast food, other restaurant purchases, home delivery, and take-out foods) and associations with weight status and percent body fat among adolescents (n=723) and parents (n=723) and related biomarkers of chronic disease among adolescents (n=367). A cross-sectional study design was used with baseline parent surveys and anthropometry/fasting blood samples from two community-based obesity studies (2006–2008) in Minnesota. Logistic regression and general linear modeling assessed associations between frequency of family dinner sources (weekly versus none in past week) and outcomes (parent and adolescent overweight/obesity and percent body fat; adolescent metabolic risk cluster z-score (MRC), cholesterol, HDL-C, LDL, triglycerides, fasting glucose, insulin and systolic blood pressure. Models accounted for clustering and adjusted for study allocation, baseline meal frequency and demographic characteristics. The odds of overweight/obesity were significantly greater when families reported at least one away-from-home dinner purchase in the past week (OR=1.2–2.6). Mean percent body fat, MRC z-scores and insulin levels were significantly greater with weekly purchases of family dinner from fast food restaurants (p’s < .05). Mean percent body fat, MRC z-scores and HDL levels were significantly higher for families who purchased weekly family dinner from take-out sources (p’s < .05). Although frequent family dinners may be beneficial for adolescents, the source of dinners is likely as important in maintaining a healthy weight. Interventions should focus on encouragement of healthful family meals. PMID:22117665
Full Text Available The objective of this study was to examine the correlation between self-perception of being overweight and weight loss intentions, eating and exercise behaviors, as well as extreme weight-loss strategies for U.S. adolescents. This study uses 50,241 observations from the Youth Risk Behavior Surveillance Survey (YRBSS 2001–2009, which were nationally representative sample of 9th- through 12th-grade students in both public and private schools in the US. This study finds that, irrespective of the weight status base on self-reported weight and height, adolescents who perceive themselves as overweight have a stronger intention to lose weight, but do not develop better eating and exercise habits, compared with their counterparts of same gender and reported weight status. Normal-weight adolescents, if they perceive themselves as overweight, are more likely to engage in health-compromising weight-loss methods. This study shows that it is critical to transform weight-loss intentions into actual behaviors among overweight/obese adolescents and improve the efficacy of behavioral interventions against childhood obesity. It also highlights the need of establishing a correct perception of body weight among normal weight adolescents to curb extreme weight-loss methods.

Our study aims to provide an in-depth analysis of behavioral strategies, psychological factors, and social contributors to adolescent weight loss and weight loss maintenance among participants in the Adolescent Weight Control Registry (AWCR). Qualitative analyses were conducted using semi-structured interview data from 40 participants from the AWCR who successfully lost ≥10 lbs and maintained their weight loss for at least one year. In contrast to existing literature, our findings suggest that primary motivating factors for adolescent weight loss may be intrinsic (e.g., desire for better health, desire to improve self-worth) rather than extrinsic. In addition, life transitions (e.g., transition to high school) were identified as substantial motivators for weight-related behavior change. Peer and parental encouragement and instrumental support were widely endorsed as central to success. The most commonly endorsed weight loss maintenance strategies included attending to dietary intake and physical activity levels, and making self-corrections when necessary. Results from this study highlight considerations for future adolescent weight control treatment development.

Obesity is a risk factor for adverse physical health outcomes during pregnancy. Much less is known about the association between obesity and maternal mental health. Evidence suggests that prenatal depression is associated with excessive weight gain during pregnancy and that this relationship may vary according to pregravid body mass index (BMI). Young women may be particularly vulnerable to postpartum depression. The objective of this study is to examine the association between prepregnancy BMI, gestational weight gain, and postpartum depressive symptoms among adolescents. Participants were 505 pregnant adolescents aged 14 to 21 years followed during pregnancy and 6 months postpartum. Data were collected via interviews and medical record abstraction. Multilevel linear mixed models were used to test the association between excessive gestational weight gain as defined by National Academy of Medicine Guidelines and postpartum depressive symptoms measured via the validated Center for Epidemiologic Studies Depression (CES-D) scale. Analyses controlled for sociodemographic factors (maternal age, race, ethnicity, relationship status), health behaviors (nutrition, physical activity), prenatal depressive symptoms, and postpartum weight retention. Prepregnancy BMI was classified as follows: 11% underweight, 53% healthy weight, 19% overweight, and 18% obese. One-half (50%) of participants exceeded recommended guidelines for gestational weight gain. Adolescents with excessive gestational weight gain who entered pregnancy overweight or obese had significantly higher postpartum depressive symptoms (β, 2.41; SE, 1.06 vs β, 2.58; SE, 1.08, respectively; both P gain. Adolescents who gained gestational weight within clinically recommended guidelines were not at risk for increased depressive symptoms. Adolescents who enter pregnancy overweight or obese and experience excessive weight gain may be at increased risk for postpartum depressive symptoms. Health care providers should

The purpose of the study was to examine the association of the gestational weight gain and prepregnancy body mass index (BMI) of low-income adolescent mothers with the risk of their children being overweight and/or obese in late adolescence. Study subjects were low-income, primiparous adolescents (n = 360) who self-identified as black and participated in the New Mothers Study in Memphis, Tennessee, and their children. Gestational weight gain was examined as a continuous variable and also categorized into overgain, recommended gain, and undergain following the 2009 Institute of Medicine guidelines. The effects of maternal prepregnancy BMI percentiles and calculated BMI were also considered. Multivariable logistic and linear regression models were used. The main outcome measures were offspring overweight, obesity, and BMI. Thirty-nine percent of offspring were overweight or obese. Higher maternal gestational weight gain increased the risk for offspring overweight and obesity. There was an interaction between gestational weight gain and prepregnancy BMI: offspring of mothers with a BMI percentile ≤76 were at greater risk of obesity with higher maternal weight gain. If mothers with a BMI percentile between the 29th and 83rd percentiles overgained, offspring were at greater risk for overweight. Using calculated BMIs, if a mother's BMI was ≤26 kg/m 2 , offspring risk for obesity was greater with higher gestational weight gain. High gestational weight gain had a larger effect on offspring overweight and obesity if maternal prepregnancy BMI percentile was ≤76. The gestational weight gain of primiparous adolescents who self-identified as black had an effect on offspring weight. Copyright © 2017 Society for Adolescent Health and Medicine.

The paper deals with parental employment status and its relationship to adolescents' self-reported health. It studies the role of the financial situation, parent-adolescent relationship and adolescent resilience in the relationship between parental employment status and adolescents' self-rated health, vitality and mental health. Multiple regression analyses were used to analyse questionnaire data obtained from 2799 adolescents (mean age 14.3) in 2006. The results show a negative association of the father's, but not mother's unemployment or non-employment with adolescents' health. Regression analyses showed that neither financial strain nor a poor parent-adolescent relationship or a low score in resilience accounted for the relationship between the father's unemployment or non-employment and poorer adolescent health. Furthermore, resilience did not work as a buffer against the negative impact of fathers' unemployment on adolescents' health.
Full Text Available Introduction: Gestational weight gain is an important modifiable factor known to influence fetal outcomes including birth weight and adiposity. Leptin is normally correlated with adiposity and is also known to increase throughout pregnancy, as the placenta becomes a source of leptin synthesis. Several studies have reported positive correlations between cord blood leptin level and either birthweight or size for gestational age, as well as body mass index (BMI. Objective: To determine the correlation of prenatal leptin concentration in pregnant adolescents with their gestational weight gain, postpartum weight retention, and weight/length of their newborn. Methods: A cohort study was conducted on pregnant Mexican adolescents from Gestational Week 26–28 to three months postpartum (n = 168 mother–child dyads. An anthropometric assessment was made of each pregnant adolescent, and the serum level of leptin and the intake of energy were determined. The newborn was evaluated each month during postpartum. Clinical records were reviewed to obtain sociodemographic data. Bivariate correlations, tests for repeating measurements and logistic regression models were performed. Results: Leptin concentration gradually increased during the third trimester of pregnancy. At Gestation Week 36, leptin level correlated with gestational weight gain. When comparing adolescents that had the lowest and highest concentration of leptin, the former presented a mean of 6 kg less in gestational weight gain (inter-subject leptin concentration, p = 0.001; inter-subject energy intake, p = 0.497. Leptin concentration and gestational weight gain exerted an effect on the weight of the newborn (inter-subject leptin concentration for Week 32, p = 0.024; inter-subject gestational weight gain, p = 0.011. Newborn length was associated with leptin concentration at Week 28 (leptin effect, p = 0.003; effect of gestational weight gain, p = 0.722. Conclusions: Pregnant adolescents with

Individuals born extremely preterm are exposed to significant perinatal stresses that are associated with an increased risk of psychopathology. However, a paucity of longitudinal studies has prevented the empirical examination of long-term, dynamic effects of perinatal adversity on mental health. Here, internalizing and externalizing problems from adolescence through adulthood were compared in individuals born at extremely low birth weight (ELBW; 2,500 g). Internalizing and externalizing data were collected over 20 years in three waves, during adolescence, young adulthood, and adulthood. Growth models were used to compare longitudinal trajectories in a geographically based sample of 151 ELBW survivors and 137 NBW control participants born between 1977 and 1982 matched for age, sex, and socioeconomic status at age 8. After adjusting for sex, socioeconomic and immigrant status, and family functioning, ELBW survivors failed to show the normative, age-related decline in internalizing problems over time relative to their NBW peers (β = .21; p Self-esteem (but not physical health, IQ, or maternal mood) partially mediated the association between ELBW status and internalizing problems. Extremely low birth weight survivors experienced a blunting of the expected improvement in depression and anxiety from adolescence to adulthood. These findings suggest that altered physiological regulatory systems supporting emotional and cognitive processing may contribute to the maintenance of internalizing problems in this population. © 2018 Association for Child and Adolescent Mental Health.

Self-reported weight and height are commonly used in lieu of direct measurements of weight and height in large epidemiological surveys due to inevitable constraints such as budget and human resource. However, the validity of self-reported weight and height, particularly among adolescents, needs to be verified as misreporting could lead to misclassification of body mass index and therefore overestimation or underestimation of the burden of BMI-related diseases. The objective of this study was to determine the validity of self-reported weight and height among Malaysian secondary school children. Both self-reported and directly measured weight and height of a subgroup of 663 apparently healthy schoolchildren from the Malaysian Adolescent Health Risk Behaviour (MyAHRB) survey 2013/2014 were analysed. Respondents were required to report their current body weight and height via a self-administrative questionnaire before they were measured by investigators. The validity of self-reported against directly measured weight and height was examined using intraclass correlation coefficient (ICC), the Bland-Altman plot and weighted Kappa statistics. There was very good intraclass correlation between self-reported and directly measured weight [r = 0.96, 95% confidence interval (CI): 0.93, 0.97] and height (r = 0.94, 95% CI: 0.90, 0.96). In addition the Bland-Altman plots indicated that the mean difference between self-reported and direct measurement was relatively small. The mean difference (self-reported minus direct measurements) was, for boys: weight, -2.1 kg; height, -1.6 cm; BMI, -0.44 kg/m 2 and girls: weight, -1.2 kg; height, -0.9 cm; BMI, -0.3 kg/m 2 . However, 95% limits of agreement were wide which indicated substantial discrepancies between self-reported and direct measurements method at the individual level. Nonetheless, the weighted Kappa statistics demonstrated a substantial agreement between BMI status categorised based on self-reported weight and height
Background Previous research with adolescents has shown associations of body weight, weight control concerns and behaviors with eating disorder symptoms, but it is unclear whether these associations are direct or whether a mediating effect exists. This study was conducted to investigate the prevalence of overweight and obesity, weight control concerns and behaviors, and eating disorder symptoms and to examine the mediating function of weight control concerns and behaviors on the relationship between body mass index (BMI) and eating disorder symptoms among non-clinical adolescents in China. Methods A cross-sectional survey among 2019 adolescent girls and 1525 adolescent boys in the 7th, 8th, 10th and 11th grades from seven cities in China was conducted. Information on weight control concerns and behaviors, and eating disorder symptoms (Eating Disorder Inventory-3) were collected from the adolescents using a self-administrated questionnaire. Results Weight control concerns and behaviors, and eating disorder symptoms were prevalent among the study population. A high proportion of adolescents scored at or above the threshold on the eating disorder inventory (EDI) subscale such as bulimia, interoceptive deficits, perfectionism, and maturity fears, which indicated eating disorder symptoms. High BMI was significantly associated with high score of drive for thinness, body dissatisfaction, bulimia, low self-esteem, interceptive deficits and maturity fears, so do perceived body weight status. Almost all weight control concerns and behaviors we investigated were significantly associated with high EDI subscale scores. When weight control concerns were added to the model, as shown in the model, the association between BMI and tendency of drive to thinness and bulimia was attenuated but still kept significant. The association between BMI and body dissatisfaction were no further significant. The association of BMI and drive for thinness, body dissatisfaction and bulimia was

Verbal harassment, such as bullying and hate speech, has received considerable attention recently, but less is known about weight-based teasing and its potential harmful effects on young people's psychosocial well-being. To determine the associations of weight-based teasing and body satisfaction, self-esteem, depressive symptoms, and suicidal ideation and suicide attempts using a large sample of adolescents. Secondary analysis of survey and anthropometric data. Ethnically and socioeconomically diverse communities in the urban and suburban school districts of the Minneapolis/St Paul metropolitan area. A school-based sample of 4746 adolescents in grades 7 to 12 at 31 public middle schools and high schools. Weight-based teasing from peers or family members, body satisfaction, self-esteem, depressive symptoms, and suicidal ideation and suicide attempts. Of the eligible students, 81.5% participated; 30.0% of adolescent girls and 24.7% of adolescent boys were teased by peers, and 28.7% of adolescent girls and 16.1% of adolescent boys were teased by family members. Approximately 14.6% of adolescent girls and 9.6% of adolescent boys reported teasing from both of these sources. Teasing about body weight was consistently associated with low body satisfaction, low self-esteem, high depressive symptoms, and thinking about and attempting suicide, even after controlling for actual body weight. These associations held for adolescent boys and girls, across racial, ethnic, and weight groups. Furthermore, teasing from 2 sources was associated with a higher prevalence of emotional health problems than either teasing from a single source or no teasing. Physicians and other health care providers should recognize the importance of weight-based teasing for young patients. Policy, programs, and education should focus on increasing awareness of what constitutes weight-based teasing, its potentially harmful effects on adolescents' emotional well-being, and reduction of this behavior.

Full Text Available IntroductionAs with most emerging nations, Brazil lacks up-to-date data on the prevalence of obesity and overweight among its children. Of particular concern is the lack of data on children in early adolescence, considered by many to be the crucial stage for weight-related healthcare.ObjectiveTo assess regional, socioeconomic, and gender differences in the prevalence of obesity and overweight among Brazilian early adolescents.MethodsA cross-sectional study was conducted on a racially diverse sample of students aged 10–13 years, from schools in three geographic regions (north, northeast, south (N = 1,738. Data on gender, age, race, socioeconomic status (SES, weight, and height were obtained. Weight class was calculated from age- and gender-adjusted body mass index, based on children’s weight and height. Bivariate and multivariable analyses, with post hoc tests, were conducted to estimate differences between groups and were corrected for multiple comparisons. Procedures were approved by institutional review boards at study sites.ResultsAnalyses revealed a higher prevalence of obesity and/or overweight among: (1 children of higher SES; (2 children in southern Brazil; (3 males; and (4 Black females.ConclusionThe most salient predictor of weight risk among Brazilian early adolescents is higher SES. This finding is consistent with previous findings of an inverse social gradient, in weight risk, among emerging-nation population groups.

Previous research has shown that adolescents' attention for a peer is determined by the peer's status. This study examined how it is also determined by the status of the perceiving adolescent, and the gender of both parties involved (perceiver and perceived). Participants were 122 early adolescents (M age = 11.0 years) who completed sociometric measures and eye-tracking recordings of visual fixations at pictures of high-status (popular) and low-status (unpopular) classmates. Automatic attention (first-gaze preference) and controlled attention (total gaze time) were measured. Target popularity was associated with both measures of attention. These associations were further moderated by perceiver popularity and perceiver and target gender. Popular adolescents attracted attention especially from other popular adolescents. Popular boys attracted attention especially from girls. © 2013 The Authors. Child Development © 2013 Society for Research in Child Development, Inc.

Clinicians currently use different low-weight cut-offs both to diagnose anorexia nervosa (AN) and to determine AN severity in adolescent girls. The purpose of this study was to evaluate the clinical utility of existing cut-offs and severity criteria by determining which are most strongly associated with risk for low bone mineral density (BMD). Height adjusted BMD Z scores were calculated for 352 females: 262 with AN and 90 healthy controls (controls) (12-20.5 years), using data from the BMD in Childhood Study, for the lumbar spine, whole body less head, and total hip. For most cut-offs used to define low weight (5th or 10th BMI percentile, BMI of 17.5 or 18.5, and 85 or 90% of median BMI), AN had lower BMD Z scores than controls. AN at >85 or >90% expected body weight for height (EBW-Ht) did not differ in BMD Z scores from controls, but differed significantly from AN at ≤85 or ≤90% EBW-Ht. Among AN, any amenorrhea was associated with lower BMD. AN had lower BMD than controls across DSM-5 and The Society for Adolescent Health and Medicine (SAHM) severity categories. The SAHM moderate severity classification was differentiated from the mildly malnourished classification by lower BMD at hip and spine sites. Amenorrhea and %EBW-Ht ≤ 85 or ≤ 90% are markers of severity of bone loss within AN. Among severity categories, BMI Z scores (SAHM) may have the greatest utility in assessing the degree of malnutrition in adolescent girls that corresponds to lower BMD. © 2017 Wiley Periodicals, Inc.

Baseline (preoperative) data from Teen Longitudinal Assessment of Bariatric Surgery, a prospective multicenter observational study of 242 adolescents with severe obesity (MedianBMI = 50.5 kg/m(2); Meanage = 17.1; 75.6% female; 71.9% white) undergoing WLS, were used to examine the impact of demographics, body mass index (BMI), presence/absence of 16 comorbid conditions, and a cumulative comorbidity load (CLoad) index on WRQOL scores (Impact of Weight on Quality of Life-Kids). WRQOL was significantly lower than reference samples of healthy weight, overweight, and obese samples. Of 16 comorbid conditions, the most prevalent were dyslipidemia (74.4%), chronic pain (58.3%), and obstructive sleep apnea (56.6%). Male subjects had a greater CLoad (P = .01) and BMI (P = .01), yet less impairment in total WRQOL (P conditions (eg, stress urinary incontinence) also emerged as contributors to lower WRQOL. WRQOL impairment is substantial for adolescents with severe obesity undergoing WLS, with predictors varying by sex. These patient-data highlight targets for education, support, and adjunctive care referrals before WLS. Furthermore, they provide a comprehensive empirical base for understanding heterogeneity in adolescent WRQOL outcomes after WLS, as weight and comorbidity profiles change over time.

The Dietary Approaches to Stop Hypertension (DASH) diet is associated with lower blood pressure and reduced risk of cardiovascular disease among adults, but little is known about accordance with this dietary pattern or health benefits among children and adolescents. The objectives were to evaluate accordance with the DASH diet, differences over time, and the association with health attributes among a nationally representative sample of US children and adolescents. Cross-sectional data from the 2003-2012 National Health and Nutrition Examination Surveys (NHANES) were analyzed. Data from 9,793 individuals aged 8 to 18 years were examined. DASH accordance was estimated based on nine nutrient targets: total fat, saturated fat, protein, cholesterol, fiber, calcium, magnesium, potassium, and sodium; possible score range is 0 to 9. Accordance with the DASH diet across time was examined comparing the 2011-2012 to 2003-2004 NHANES surveys. The association between DASH score and weight status was examined using multinomial logistic regression, and the associations with waist circumference, systolic blood pressure, and diastolic blood pressure were examined using multivariable linear regression. Accordance with the DASH diet was low across the age groups, with a range of mean DASH scores from 1.48 to 2.14. There were no significant changes across time. DASH score was inversely associated with systolic blood pressure (mm Hg) among 14- to 18-year-olds (β=-.46; 95% CI -.83 to -.09) among the larger sample of participants who completed at least one dietary recall, but no significant differences were seen in other age categories. In the subsample of participants with both dietary recalls, a significant inverse association was seen between DASH score and systolic blood pressure for 11- to 13-year-olds (β=-.57; 95% CI -1.02 to -.12). There were no significant associations between this dietary pattern and weight status, waist circumference, or diastolic blood pressure. Few US

Adolescent obesity is a well-known worldwide issue with growing prevalence and complications. The concept of body image and complications of its misperception has been noted more recently. Life satisfaction (LS) and self-rated health (SRH) have also been known as independent morbidity and mortality factors. The objective of this study was to evaluate the associations of perceived weight status (body image) and actual body mass index (BMI), with LS and SRH in a nationally representative sample of a pediatric population in Iran, as a country located in the Middle East and North Africa region. This nationwide population-based survey was conducted among 5,570 (2,784 female and 2,786 male) Iranian students, aged 10-18 years, living in urban and rural areas of 27 provinces, which were selected via multistage sampling method. Agreement between BMI and perceived weight status (underweight, about right and overweight/obesity) was assessed. Adjusted association between BMI and perceived weight status with LS and SRH was assessed using multiple logistic regressions after adjustment for potential confounders. Nearly 40 % of the participants misperceived their body image. Misperception as overweight or underweight was found to be associated with lower odds for both LS and SRH [overweight SRH OR 0.796 (95 % CI 0.647-980), underweight SRH OR 0.701 (95 % CI 0.588-0.835), overweight LS OR 0.884 (95 % CI 0.718-998), underweight LS OR = 0.676 (95 % CI 0.577-0.793)], whereas the association between actual BMI with LS and SRH was not statistically significant (P value > 0.05). A mismatch between BMI and body weight perception was found in this study. Moreover, LS and SRH were not related with BMI, but had negative association with body weight perception.

Full Text Available Using a nationally representative sample of 142 783 middle school (13–15 years old and high school (16–18 years old students in South Korea, this study examined whether (1 overweight and obesity are more likely to be associated with lower self-reported school performance; (2 overweight and obese students are more likely to enrol in a vocational high school as opposed to a general high school; (3 the association between obesity and poorer self-reported school performance is mediated through body image stress and health status. We found that excess weight was negatively associated with self-reported school performance among middle and general high school students, and that obese students had a higher probability of being enrolled in a vocational over a general high school. We did not find strong evidence on the mediating role of body image stress and health status.

Using data from the National Longitudinal Survey of Adolescent Health (Add Health), I investigate the relationship between birth weight and cognitive development among adolescents aged 12-17. Initial OLS regression models reveal a significant, positive relationship between low birth weight and verbal ability. Controlling for demographic, socioeconomic, and other adolescent characteristics modifies, but does not eliminate, this relationship. Additional models that stratify the sample by parental education illustrate the greater importance of other family and adolescent characteristics for cognitive development in adolescence, and a diminished role of birth weight. In the final section of the paper, fixed effects models of non-twin full siblings indicate no significant association between birth weight and verbal ability, suggesting that traditional cross-sectional models overstate the influence of birth weight for cognitive development in adolescence.

To evaluate the association between nutritional status, lung function and morbidity in a 36-month cohort in children and adolescents with cystic fibrosis. Prospective cohort of children and adolescents with cystic fibrosis aged 1-15 years. At the baseline, the nutritional status was determined by weight-for-height and body mass index-for-age for children 36 months. Those classified bellow the 50th percentile had a RR of 4.61 (95%CI 0.89; 23.81) to present the same outcome. Nutritional status was not a risk factor for morbidity in this cohort. Nutritional deficit was associated with impaired lung function, but not with morbidity in children and adolescents with cystic fibrosis.

Micronutrient deficiencies can damage the health of adolescent girls and their offspring. There is a lack of population-based data on the micronutrient status of adolescents in Sub-Saharan Africa. We conducted a cross-sectional, population-based study to examine the biochemical status, prevalence of deficiency, dietary intake, and food sources of selected micronutrients among adolescent girls in Central Mozambique. Separate groups of study participants were recruited in 2 seasons in 2010. The participants were girls between 14 and 19 years of age (n = 551) from 1 urban area and 2 rural districts. Micronutrient status indicators were analyzed from blood and urine samples. Twenty-four-hour dietary recalls were also carried out. The overall prevalence with 95% confidence interval (calculated using sampling weights) among nonpregnant girls was 42.4% (37.2%-47.8%; n = 466) for anemia, 27.4% (23.1%-32.2%; n = 427) for low serum ferritin, 32.7% (27.7%-38.1%; n = 423) for low serum zinc, 14.7% (11.2%-19.0%; n = 426) for low plasma retinol, and 4.1% (2.9%-5.8%; n = 448) for low serum folate. The selenium status was considered sufficient. Mild to moderate iodine deficiency was found in the rural districts, whereas the iodine status of urban girls was adequate. Significantly lower serum folate concentrations were found in the urban area compared to the rural districts. The seasonal differences in vitamin A intake were significant. The intakes of micronutrients from animal source foods were small. In summary, adolescent Mozambican girls are at risk of several micronutrient deficiencies. This raises concern especially because adolescent motherhood is common in the region. Actions need to be taken to prevent and control micronutrient deficiencies. Copyright © 2015 Elsevier Inc.

Full Text Available There are no documented studies on socioeconomic status (SES and body mass index (BMI among Mauritian adolescents. This study aimed to determine the relationships between SES and BMI among adolescents with focus on diet quality and physical activity (PA as mediating factors. Mauritian school adolescents (=200; 96 males, 104 females were recruited using multistage sampling. Participants completed a self-reported questionnaire. Height and weight were measured and used to calculate BMI (categorised into underweight, healthy-weight, overweight, obese. Chi-square test, Pearson correlation, and Independent samples -test were used for statistical analysis. A negative association was found between SES and BMI (2=8.15%, <0.05. Diet quality, time spent in PA at school (=0.000, but not total PA (=0.562, were significantly associated with high SES. Poor diet quality and less time spent in PA at school could explain BMI discrepancies between SES groups.
Full Text Available Research Question: What is the influence of maternal nutritional status during pregnancy on the birth weight? Objective: To assess the effect of maternal nutritional status during pregnancy on the birth weight of the baby among tea tribe women in Dibrugarh district. Study Design: Field-based cohort study. Setting: Five tea estates in Dibrugarh District, Assam. Period of Study: One year (April 1998 to April 1999. Participants: A cohort of non-pregnant currently married tea garden women of reproductive age group (15-44 years from similar socio-economic background. Materials and Methods: Oral questionnaire for age, family structure, obstetric history, annual income, and period of gestation. Anthropometric measurements of weight and height were recorded using bathroom scales and the anthropometric rod. Measurements of weight were repeated during the first, second, and third trimesters of pregnancy. Birth weight of the baby was recorded at delivery, irrespective of the period of gestation and mode of delivery. Statistical Analysis: Correlation co-efficient, standard deviation, and regression analysis. Results and Conclusions: Of all, 88% mothers had pre-pregnant weight of < 45 kg, and 61% babies had birth weight < 2500 gm. Subjects with better pre-pregnant weight had corresponding favorable total weight gain, resulting in better birth weight of the babies. Pre-pregnant weight had direct positive linear relationship with the birth weight. There is a need to improve the nutritional status of the adolescent girl in order to build up her pre-pregnant weight for a favorable birth weight.

Malnutrition is considered a problem that limits learning ability (cognitive function), which is related to poor academic achievement results. This study aimed to determine the relationship of nutritional status with academic achievement in adolescents. A cross-sectional study was conducted on 126 junior high school students ranging from 12 to 15 years in Batubara, North Sumatra in January 2015. Nutritional status is determined by weight for height. Academic achievement was recorded from the final results of their school exams. The value of intelligence quotient (IQ) was assessed by using the Aptitude Test. Data were then analyzed by using Spearman correlation and Chi-Square test. In conclusion, there was no significant difference between nutritional status with IQ score (p=0,540) but showed a significant relationship (p=0.003) between normal nutritional status with the total value of the report card with positive weak correlation strength (r=0.342). There was also a significant difference (p=0.020) and moderate positive correlation (r=0.541) between overweight with academic achievement based on mathematics.

Full Text Available Abstract Background Self-reported weight and height are commonly used in lieu of direct measurements of weight and height in large epidemiological surveys due to inevitable constraints such as budget and human resource. However, the validity of self-reported weight and height, particularly among adolescents, needs to be verified as misreporting could lead to misclassification of body mass index and therefore overestimation or underestimation of the burden of BMI-related diseases. The objective of this study was to determine the validity of self-reported weight and height among Malaysian secondary school children. Methods Both self-reported and directly measured weight and height of a subgroup of 663 apparently healthy schoolchildren from the Malaysian Adolescent Health Risk Behaviour (MyAHRB survey 2013/2014 were analysed. Respondents were required to report their current body weight and height via a self-administrative questionnaire before they were measured by investigators. The validity of self-reported against directly measured weight and height was examined using intraclass correlation coefficient (ICC, the Bland-Altman plot and weighted Kappa statistics. Results There was very good intraclass correlation between self-reported and directly measured weight [r = 0.96, 95% confidence interval (CI: 0.93, 0.97] and height (r = 0.94, 95% CI: 0.90, 0.96. In addition the Bland-Altman plots indicated that the mean difference between self-reported and direct measurement was relatively small. The mean difference (self-reported minus direct measurements was, for boys: weight, −2.1 kg; height, −1.6 cm; BMI, −0.44 kg/m2 and girls: weight, −1.2 kg; height, −0.9 cm; BMI, −0.3 kg/m2. However, 95% limits of agreement were wide which indicated substantial discrepancies between self-reported and direct measurements method at the individual level. Nonetheless, the weighted Kappa statistics demonstrated a substantial agreement between BMI

To investigate the differences in the dietary patterns of Polish overweight and normal weight adolescents. The study was carried out on a group of 1906 pupils from gymnasium (lower secondary school) aged 13-15 years, of whom 953 were overweight and 953 had normal body mass. The sample was taken from a representative group of 8386 pupils. Their height and body weight were measured, and their BMI was calculated. Overweight was defined as BMI ł85 percentile for gender and age. Using the method of "selection in pairs", each overweight pupil was paired with a pupil with normal body weight. The research tool was a self-reported questionnaire, containing questions regarding how often selected food products were usually consumed during the week, how regularly basic meals (breakfast, lunch, supper) were eaten, and data on snacking. Overweight adolescents consumed unhealthy products such as sweets and crisps significantly less often than their peers with appropriate body mass. Overweight girls ate dark bread significantly more often, and consumed soft drinks less often than their peers with normal weight. Overweight adolescents had more irregular meals than those with normal weight: only 44% overweight adolescents had breakfast every day, significantly less than adolescents with normal weight. Nevertheless, overweight teenagers snacked significantly less often than young people with normal body mass. The overweight teenagers also less often chose snacks with high fat content, sugar and salt, and more often vegetables, fruits, as well as yoghurt and kefir. 1. Our study shows that compliance of low energy diet alone does not ensure the maintenance of normal body weight. Irregularity of meals and breakfast skipping play an important role in developing overweight and obesity in adolescents. 2. In future studies on dietary patterns in a larger sample of adolescents, emphasis should be placed on adding questions about portion size, food preparation and meal time. Eating

We examined the association of body mass index (BMI), body weight perception, and weight control behaviors with problematic Internet use in a nationwide sample of Korean adolescents. Cross-sectional data from the 2010 Korean Youth Risk Behavior Web-based Survey collected from 37,041 boys and 33,655 girls in middle- and high- schools (grades 7-12) were analyzed. Participants were classified into groups based on BMI (underweight, normal weight, overweight, and obese), body weight perception (underweight, normal weight, and overweight), and weight control behavior (no weight control behavior, appropriate weight control behavior, inappropriate weight control behavior). The risk of problematic Internet use was assessed with the Korean Internet Addiction Proneness Scale for Youth-Short Form. Both boys and girls with inappropriate weight control behavior were more likely to have problematic Internet use. Underweight, overweight, and obese boys and girls were more likely to have problematic Internet use. For both boys and girls, subjective perception of underweight and overweight were positively associated with problematic Internet use. Given the negative effect of inappropriate weight control behavior, special attention needs to be given to adolescents' inappropriate weight control behavior, and an educational intervention for adolescents to control their weight in healthy ways is needed.

Background Bariatric surgery is one of the few effective treatments for morbid obesity but the weight loss and other health related outcomes for this procedure in large, diverse adolescent patient populations are not well characterized. Objective To analyze the prospective Bariatric Outcomes Longitudinal Database (BOLD) to determine the weight loss and health related outcomes in adolescents. Setting BOLD data is collected from 423 surgeons at 360 facilities in the United States. Methods Main outcome measures included anthropometric and comorbidity status at baseline (n=890) and at 3 (n=786), 6 (n=541), and 12 (n=259) months after surgery. Adolescents (75% female; 68% non-Hispanic white, 14% Hispanic, 11% non-Hispanic black, and 6% other) age 11-to-19 years were included in the analyses. Results The overall one year mean weight loss for those who underwent gastric bypass surgery was more than twice that of those who underwent adjustable gastric band surgery (48.6 kg versus 20 kg, Psurgery types (Psurgery. There were a total of 45 readmissions among gastric bypass patients and 10 among adjustable gastric band patients with 29 and 8 reoperations required, respectively. Conclusions Weight loss at 3-, 6-, and 12-months after surgery is approximately double in adolescent males and females who underwent gastric bypass surgery versus those who underwent adjustable gastric band surgery. Bariatric surgery can safely and substantially reduce weight and related comorbidities in morbidly obese adolescents for at least 1 year. PMID:22542199

To determine the relationship between current substance use and unhealthy weight loss practices (UWLP) among 12-to-18 year olds. Participants were 12-to-18 year olds who completed the 2013 Youth Risk Behavior Survey in Florida (N = 5620). Current alcohol, tobacco, and marijuana use was self-reported based on last 30-day use. UWLP was defined based on self-report of at least one of three methods to lose weight in last 30-days: (1) ≥24 h of fasting, (2) diet pill use, and (3) laxative use/purging. The reference group included those with no reported UWLP. Logistic regression models adjusted for age, gender, race/ethnicity, academic performance, age-sex-specific body mass index percentiles, and perceived weight status were fitted to assess relationships between UWLP and current substance use. About 15 and 41 % of adolescents reported ≥1 UWLP and use of ≥1 substance in the last 30-days, respectively. Over half (60.1 %) of adolescents who reported substance use engaged in UWLP (p < 0.0001). The prevalence of current alcohol use (50.6 %) was the highest among those who reported UWLP, followed by marijuana (31.9 %), tobacco (19.7 %), and cocaine (10.5 %) use. Adolescents who reported current tobacco [adjusted odds ratio (AOR) 2.7, 95 % confidence interval (CI) 2.1-3.6], alcohol (AOR 2.2, 95 % CI 1.9-2.6), or marijuana (AOR 2.1, 95 % CI 1.7-2.5) use had significantly higher odds of UWLP compared to their non-user counterparts. This cross-sectional study shows that substance use and UWLP behaviors are likely to co-exist in adolescents. Further studies are necessary to determine the temporal relationship between substance use and UWLP. It is recommended that intervention programs for youth consider targeting these multiple health risk behaviors.

Purpose To examine parent and family variables in relation to adolescent weight control and eating behaviors, body satisfaction, and importance of thinness among overweight adolescents. Methods This study examined parent-reported use of weight control behaviors (i.e., healthy and unhealthy behaviors, behavioral changes, other diet strategies), parent psychosocial functioning (i.e., depression, self-esteem, body satisfaction, importance of thinness), and family functioning (i.e., cohesion and adaptability) in relation to adolescent weight control and eating behaviors, body satisfaction, and importance of thinness. Surveys were completed by 103 overweight (BMI ≥ 85th percentile) adolescents, ages 12 to 20, and their parents. Height and weight were also measured. Linear regression equations were used for continuous outcomes and logistic regression equations for dichotomous outcomes. Results Adolescent report of lower body satisfaction and engagement in more “severe” or less healthy forms of weight control behavior were associated with parent weight control behaviors. Adolescent report of overeating was associated with lower scores of family cohesion and adaptability. Adolescent report of lower body satisfaction was positively associated with parent report of body satisfaction and self-esteem. Adolescent report of greater importance placed on thinness was associated with parent report of lower self-esteem. Conclusions Findings indicate that several parent and family variables are associated with weight control behaviors, episodes of overeating, and body satisfaction and importance of thinness among overweight adolescents. Parent weight control behaviors and adolescent cognitions about body image may be important variables to target within intervention research and treatment programs for overweight youth. PMID:20708565

This umbrella review analysed the relationships between family variables and child/adolescent body weight, diet and physical activity. In line with theories of health behaviour change, it was assumed that behaviour-specific family variables (i.e. beliefs, perceptions and practices referring to food intake or physical activity) would have stronger support than more general family variables (i.e. socio-economic status or general parental practices). Data obtained from 18 systematic reviews (examining 375 quantitative studies) were analysed. Reviews of experimental trials generally supported the effectiveness of reward/positive reinforcement parental strategies, parental involvement in treatment or prevention programmes, and cognitive-behavioural treatment in reducing child/adolescent body mass and/or obesity. Results across reviews of correlational studies indicated that healthy nutrition of children/adolescents was related to only one parental practice (parental monitoring), but was associated with several behaviour-specific family variables (e.g. a lack of restrictive control over food choices, high intake of healthy foods and low intake of unhealthy foods by parents and siblings, low pressure to consume foods). With regard to adolescent physical activity, stronger support was also found for behaviour-specific variables (e.g. physical activity of siblings), and for certain socio-economic variables (e.g. parental education). Child and adolescent obesity prevention programmes should account for behaviour-specific family variables. © 2011 Blackwell Publishing Ltd.

To evaluate the effect of sibutramine on weight loss in obese adolescents. A double-blind controlled study lasting 13 months. The study included 73 obese adolescents of both sexes aged between 10 and 18 years. Laboratory tests and imaging studies were performed before, during wash-out, and at the end of 13 months. The percentage of patients who lost 10% of their initial weight in the placebo group was 46%, and in the sibutramine group was 75%. When placebo was used, average weight rose by 1.61 kg, and BMI decreased by 0.24 kg/m(2) whereas with the use of sibutramine, weight decreased by 4.47 kg, and average BMI decreased, 2.38 kg/m(2), with p Sibutramine induced significantly more weight loss in obese adolescents compared with placebo, without significant side effects. The weight loss curve was different depending on the moment sibutramine was introduced. This finding indicates that the best time to start sibutramine is when adhesion begins to fail.

The prevalence of obesity is highest in older persons and a correct self-perception of body weight status is necessary for optimal weight control. The aim of this study was to determine self-perception of, and satisfaction with, body weight status, and to compare current versus ideal body image in a large, nationally representative sample of older people. Furthermore, determinants of misperception were explored. A cross-sectional study. The Longitudinal Aging Study Amsterdam (LASA), conducted in a population-based sample in the Netherlands. 1295 men and women aged 60-96 years. Body weight status was assessed using measured weight and height. Self-perceived body weight status, satisfaction with body weight and current and ideal body image were also assessed. Multiple logistic regression analysis was used to investigate the association of age, educational level and objectively measured BMI with underestimation of body weight status. The prevalence of obesity was 19.9% in men and 29.3% in women. The agreement between objective and self-perceived body weight status was low (Kappa 99% of obese participants desired to be thinner (ideal body image < current image). Only 4.4% of obese men and 12.3% of obese women perceived their body weight status correctly. Higher age (women), lower educational level (men) and higher BMI (all) were associated with greater underestimation of body weight status. Many older persons misperceive their body weight status. Future actions to improve body weight perception in older persons are necessary to increase the impact of public health campaigns focussing on a healthy body weight in old age.

Cognitive deficits occur in a subset of individuals with obesity. Deficits can be reversed with bariatric surgery, though cognitive recovery is not equally exhibited across patients. Recent work has found that obesity during adolescence portends medical complications in adulthood; it is unknown if obesity in adolescence predicts adult cognition or cognitive recovery after weight loss surgery. The present study examines the relationship between weight history and cognitive function in obese adults undergoing bariatric surgery. Academic medical centers with bariatric care services. Seventy-eight bariatric surgery patients (mean age = 43.2 years) enrolled in an ancillary study to the Longitudinal Assessment of Bariatric Surgery (LABS) project completed a questionnaire recalling weight history at age 18. Cognitive testing was completed preoperatively and at 12-month follow-up. Weight status at age 18 was linked to performance in several aspects of cognition. Higher body mass index at age 18 predicted poorer preoperative verbal fluency (B = -.26, P = .045) as well as postoperative cognitive recovery in attention (B = -.30, P = .01) at 12-month follow-up. Higher body mass index at age 18 predicts verbal fluency performance in adults with obesity, as well as postoperative recovery of attention after bariatric surgery. The mechanisms underlying this connection are not fully clear, though findings may reflect effects of obesity on the brain during a crucial period of neural maturation or duration of obesity and cumulative impact of co-morbidities on cognition. Future work examining possible causal factors involved in these relationships is needed. Copyright © 2016 American Society for Bariatric Surgery. Published by Elsevier Inc. All rights reserved.

We compared participants' self-perception of their weight with the World Health Organisation (WHO) definition for BMI categories among undergraduate university students undertaking health related academic programmes in Ghana. Also, we investigated factors associated to the underestimation of weight status in this sample. This cross-sectional study was conducted among a sample of 368 undergraduate students. Anthropometric measurements of weight and height were measured with appropriate tools and computed into Body Mass Index (BMI) categorised based on WHO classifications. Waist and hip circumferences were also measured appropriately. Participants' self-perception of weight status was assessed by the question: How do you perceive your weight? (a) Underweight, (b) normal weight, (c) overweight, and (d) obese. The BMI-measured weight status was compared to the self-perceived weight status by cross-tabulation, Kappa statistics of agreement and χ(2) for trend analysis. Factors associated with misperception of weight status was measured using univariate and multivariable analysis. Thirteen percent (n=48) of the participants were overweight/obesity (BMI) and 31.5% had central obesity. Overall, 20.6% of the participants misperceived their weight status in which 78.9% of them underestimated it. Among overweight/obese participants, 41.7% self-perceived themselves accurately. Whereas 10.6% of normal weight participants underestimated their weight status, over half (58.3%) of overweight/obese participants did so. Factors that were associated with underestimation of weight status were having overweight/obesity (BMI) and central obesity. Underestimation of weight status was frequent. Health professionals and related government agencies should develop intervention programmes to empower young people to have accurate weight status perception.

Prevention of body dissatisfaction development is critical for minimizing adverse effects of poor body esteem on eating behaviors, self-esteem, and overall health. Research has examined body esteem and its correlates largely in pre-adolescents and adolescents; however, important questions remain about factors influencing body esteem of younger children. The main purpose of this study was to test moderation by children's gender and weight status of the relation of maternal controlling feeding practices to 1st graders' body esteem. The Body Esteem Scale (BES) and anthropometric measurements were completed during one-on-one child interviews at school. Mothers completed the Child Feeding Questionnaire (restriction, monitoring, concern, self-assessed maternal weight). A total of 410 mother/child dyads (202 girls) participated. Percent of children classified as overweight (BMI-for-age ≥85th) was: girls - 29%; boys - 27%. Gender moderated the relation between restriction and body esteem (β = -.140, p = .05), with maternal restriction predicting body esteem in girls but not boys. The hypothesized three-way interaction among gender, child weight status, and monitoring was confirmed. Monitoring was significantly inversely related to body esteem only for overweight/obese girls (b = -1.630). The moderating influence of gender or gender and weight status on the link between maternal feeding practices and body esteem suggests the importance of body esteem interventions for girls as early as first grade.

Full Text Available OBJECTIVES: The purpose of this study was to examine secular changes in growth and nutritional status of Mozambican children and adolescents between 1992, 1999 and 2012. METHODS: 3374 subjects (1600 boys, 1774 girls, distributed across the three time points (523 subjects in 1992; 1565 in 1999; and 1286 in 2012, were studied. Height and weight were measured, BMI was computed, and WHO cut-points were used to define nutritional status. ANCOVA models were used to compare height, weight and BMI across study years; chi-square was used to determine differences in the nutritional status prevalence across the years. RESULTS: Significant differences for boys were found for height and weight (p2012, and those from 2012 had the highest BMI (1999<2012. In general, similar patterns were observed when mean values were analyzed by age. A positive trend was observed for overweight and obesity prevalences, whereas a negative trend emerged for wasting, stunting-wasting (in boys, and normal-weight (in girls; no clear trend was evident for stunting. CONCLUSION: Significant positive changes in growth and nutritional status were observed among Mozambican youth from 1992 to 2012, which are associated with economic, social and cultural transitional processes, expressing a dual burden in this population, with reduction in malnourished youth in association with an increase in the prevalence of overweight and obesity.

Full Text Available Abstract Background Neighborhood safety may be an important social environmental determinant of overweight. We examined the relationship between perceived neighborhood safety and overweight status, and assessed the validity of reported neighborhood safety among a representative community sample of urban adolescents (who were racially and ethnically diverse. Methods Data come from the 2006 Boston Youth Survey, a cross-sectional study in which public high school students in Boston, MA completed a pencil-and-paper survey. The study used a two-stage, stratified sampling design whereby schools and then 9th–12th grade classrooms within schools were selected (the analytic sample included 1,140 students. Students reported their perceptions of neighborhood safety and several associated dimensions. With self-reported height and weight data, we computed body mass index (BMI, kg/m2 for the adolescents based on CDC growth charts. Chi-square statistics and corresponding p-values were computed to compare perceived neighborhood safety by the several associated dimensions. Prevalence ratios (PRs and 95% confidence intervals (CI were calculated to examine the association between perceived neighborhood safety and the prevalence of overweight status controlling for relevant covariates and school site. Results More than one-third (35.6% of students said they always felt safe in their neighborhood, 43.9% said they sometimes felt safe, 11.6% rarely felt safe, and 8.9% never felt safe. Those students who reported that they rarely or never feel safe in their neighborhoods were more likely than those who said they always or sometimes feel safe to believe that gang violence was a serious problem in their neighborhood or school (68.0% vs. 44.1%, p p = 0.025. In the fully adjusted model (including grade and school stratified by race/ethnicity, we found a statistically significant association between feeling unsafe in one's own neighborhood and overweight status among

There are wide-ranging differences in human growth, not only between ethnic groups but also between regions. Shandong is one of the most populous provinces in China, with inequalities of regional economic status. However, no studies on the differences in development among children and adolescents in different districts have been reported. This study assessed the differences in height, weight and prevalence of obesity among children and adolescents of different socioeconomic status (SES) districts in Shandong, China. Data for this study were obtained from a large cross-sectional survey of schoolchildren. A total of 42 286 students (21 222 boys and 21 064 girls) aged 7-18 years from 16 districts participated in this study. Height and weight of all subjects were measured and BMI was calculated from their height and weight. Prevalence rates of obesity and overweight were determined by comparing calculated BMIs (kg/m(2)) to International Obesity Task Force (IOTF) cut-offs. Each of the 16 districts was assigned an SES ranking (low, moderate, high) based on per capita GDP and income in urban and rural areas. Comparisons of height, weight and the prevalence of overweight and obesity among different groups were made. Significant differences between SES groups were observed for height, weight and the prevalence of overweight and obesity. Boys and girls from high SES group were taller, heavier and more likely to be obese than their peers from moderate and low SES groups. The prevalences of combined overweight and obesity in the three SES groups were 18.46%, 21.08% and 27.31% in boys and 10.43%, 12.42% and 15.18% in girls, respectively. There have been obvious regional variations in development and the prevalence of obesity in children and adolescents in Shandong, China, These variations in development and prevalence of obesity in children and adolescents among different SES districts being related to the local SES, process of urbanization, living environments, nutritional

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 95th percentile), and 32% stunted (height-for-age 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 status of adolescents.

The perception of body image of adolescents is an instrument for nutritional assessment to health conditions. To verify the body image perception of adolescents and their parents in relation to nutritional status and blood pressure levels. Population-based study, and cross-sectional model, conducted with parents and adolescents aged 10-19 years old, in rural and urban zones in public schools. There was applied the Scale silhouettes for parents about the perception of the described body image and a question about the concern of the nutritional status of their children. There were verified the blood pressure, weight, height and waist circumference, the BMI (kg/m²) calculation of the adolescents, and the self-perceived body image. The data was expressed as average ± standard deviation and percentages. The sample consisted of 914 adolescents with a mean age of 13.12 ± 2.17 years, 56.8% female and 68.9% were eutrophic. As for blood pressure levels, 17.6% were classified in pre-hypertensive, 18.8% in stage 1 hypertension and 6% in stage 2. About the self-perception, 68% considered themselves being eutrophic and 64.75% of the parents classified their children as eutrophic. There was observed a direct and significant correlation among the body mass index, waist circumference, weight, systemic and diastolic blood pressure with the self-perception of the adolescents and the body image perceptions of the parents (ppressure, waist circumference and body image perceptions of the adolescents and their respective parents.

This study examined parenting variables (communication, monitoring) as moderators of a family-based intervention for reducing sedentary behavior (SB) in African American adolescents. As a secondary aim, a similar model was tested using adolescent weight status as the outcome. African American adolescents (n = 73; 12.45 ± 1.45 years; 60% girls; 63% overweight/obese) and caregivers were randomized to a 6-week interactive, parent-based intervention or general health condition. Parent-adolescent communication and monitoring of health behaviors were self-reported by parents. Adolescent SB was self-reported by youth. There was a significant intervention by communication interaction, such that intervention families with more positive communication showed lower adolescent SB than those with less positive communication or those in the comparison condition. No effects were found for monitoring on SB or for the model with weight status as the outcome. Parent-adolescent communication may be an effective component to integrate into health promotion programs for African American adolescents.

The purpose of this study is to estimate the proportion of adolescents meeting Healthy People 2020 health behavior recommendations for the prevention of chronic disease and to determine the association between mental health status (depression and/or conduct problems) and the likelihood of meeting these recommendations. The data used for this study are from the 2010 Washington State Healthy Youth Survey. Descriptive statistics and linear regression were utilized to estimate the proportion of adolescents meeting recommendations and associations between youth mental health status indicators and health-promoting behaviors. A small minority (5.8 %) of youth met all six recommendations in domains of tobacco abstinence, substance use abstinence, daily physical activity, breakfast consumption, weight below obese levels, and adequate sleep, though most (84.3 %) met at least three. At the aggregate level, the proportion of Washington State youth who met Healthy People 2020 guidelines exceeded targets, with the exception of substance use abstinence. A minority of youth reported guideline levels of daily physical activity (23.3 %) and sleep (39.8 %). Mental health status was strongly associated with the number of health-promoting behaviors adolescents endorsed. Interventions to increase the adoption of sleep hygiene and exercise habits should be added to an integrative positive youth development framework within school-, community-, and primary care-based adolescent health initiatives. Attention to adolescent mental health and shared risk factors may be critical for reducing barriers to healthy behavior.

To describe food consumption frequency in adolescents in the context of the financial crisis in 2012, and to analyse potential fluctuations in excess body weight between 2008 and 2012. A cross-sectional study of eating habits and excess body weight was conducted in adolescents aged 13 to 19 years old from public, subsidised and private secondary schools in Barcelona, Spain. The FRESC lifestyle risk factors survey was used, and food frequency consumption, food recommendations and body mass index were analysed according to gender, year of education and socioeconomic status. Girls ate vegetables and fruits more frequently than boys, while the prevalence of junk food consumption was higher in boys. The prevalence of compliance with food recommendations was lower than 50% for all foods, and gender and socioeconomic differences were found for eggs, red meat and soft drinks. Regarding excess body weight, boys had a higher prevalence than girls in the 2 years analysed. Furthermore, a reduction in excess body weight was observed among girls in secondary education in the highest socioeconomic groups (28.7% [95% CI: 24.8-32.6%] in 2008 to 20.5% [95% CI: 17.1-23.8%] in 2012). The prevalence of adolescents following food recommendations is low, and gender differences were found in terms of food consumption frequency, even in the context of financial crisis. There is a need to promote programmes and policies to reduce inequalities related to eating habits and excess body weight in adolescents. Copyright © 2016 SESPAS.

Although there is no definitive consensus on the impairment of neuropsychological functions, most studies of adults with Anorexia Nervosa (AN) find impaired functioning in cognitive domains such as visual-spatial abilities. The objective of this study is to assess the cognitive functions in adolescents with AN before and after weight recovery and to explore the relationship between cognitive performance and menstruation. Twenty-five female adolescents with AN were assessed by a neuropsychological battery while underweight and then following six months of treatment and weight recovery. Twenty-six healthy female subjects of a similar age were also evaluated at both time points. Underweight patients with AN showed worse cognitive performance than control subjects in immediate recall, organization and time taken to copy the Rey's Complex Figure Test (RCFT). After weight recovery, AN patients presented significant improvements in all tests, and differences between patients and controls disappeared. Patients with AN and persistence of amenorrhea at follow-up (n=8) performed worse on Block Design, delayed recall of Visual Reproduction and Stroop Test than patients with resumed menstruation (n=14) and the control group, though the two AN groups were similar in body mass index, age and psychopathological scale scores. Weight recovery improves cognitive functioning in adolescents with AN. The normalization of neuropsychological performance is better in patients who have recovered at least one menstrual cycle. The normalization of hormonal function seems to be essential for the normalization of cognitive performance, even in adolescents with a very short recovery time. © 2013.

The objective of the present work was to quantify mothers' misclassification of pre-school children's weight status and to determine factors associated with the maternal misperception. A representative sample of 2287 children aged 2-5 years was examined (GENESIS study). Mothers' perceptions of their child's weight status and the children's and mothers' anthropometric and other characteristics (sociodemographic and lifestyle) were recorded. Almost 38 % of mothers underestimated their child's weight status. The frequency of underestimation was much higher among 'at risk of being overweight' and 'overweight' children (88.3 % and 54.5 %, respectively) compared with 'underweight/normal-weight' children (18.0 %, P engaging in physical activity for less than 3 h/week and in children whose mothers had low education status, compared with their counterparts. Moreover, the higher the BMI-for-age Z-score, the greater the odds that the mother would underestimate her child's weight status. The current study demonstrated that more than one-third of mothers misclassify their children's weight status as being lower than the actual. Given that mother's weight perception might be an important determinant of child's body weight development, clinicians and health professionals should help mothers correctly classify their children's weight status, which could potentially help in the early prevention of overweight and obesity.

y personales.Introduction: the adolescence is a decisive stage with a high level of prevalence of nutritional disorders that latter remains during the adulthood and are associated with short- and long term complications. Objectives: to identify the association between excess of body weight and the interesting family pathological backgrounds and some perinatal risks, the presence of high blood pressure and its relation to the family history of high blood pressure and the increase of abdominal adiposity and finally, to identify the presence of acanthosis nigricans and its relation with the similar factors. Methods: a cross-sectional and descriptive study was conducted to characterize the nutritional status of the adolescents of the seventh grade from the "José María Heredia" secondary school during 2009-2020. Group included 192 adolescents who with a previous consent of parents underwent anthropometric measurements (weight, height, waist circumference and estimation of the body mass index and also the blood pressure and search of clinical signs of insulin resistance. A survey to parents on the family pathological backgrounds and on some data of their children was applied. Results: there was that the 20,31 % of adolescents had excess weight or obesity, which was related in a significant way to the presence of a high blood pressure and clinical signs of insulin resistance. The high blood pressure was present in the 9,9 % of adolescents without any relation to hereditary factors. Conclusions: obesity and body excess weight are a health problem in study adolescent population, which is associated with the presence of a high blood pressure and insulin resistance; there was not relation in its behavior to non-modifiable factors (family and personal pathological backgrounds.

Bariatric surgery is 1 of the few effective treatments of morbid obesity. However, the weight loss and other health-related outcomes for this procedure in large, diverse adolescent patient populations have not been well characterized. Our objective was to analyze the prospective Bariatric Outcomes Longitudinal Database (BOLD) to determine the weight loss and health related outcomes in adolescents. The BOLD data are collected from 423 surgeons at 360 facilities in the United States. The main outcome measures included the anthropometric and co-morbidity status at baseline (n = 890) and at 3 (n = 786), 6 (n = 541), and 12 (n = 259) months after surgery. Adolescents (75% female; 68% non-Hispanic white, 14% Hispanic, 11% non-Hispanic black, and 6% other) aged 11 to 19 years were included in the present analyses. The overall 1-year mean weight loss for those who underwent gastric bypass surgery was more than twice that of those who underwent adjustable gastric band surgery (48.6 versus 20 kg, P surgery types (P surgery. A total of 45 readmissions occurred among gastric bypass patients and 10 among adjustable gastric band patients, with 29 and 8 reoperations required, respectively. The weight loss at 3, 6, and 12 months after surgery is approximately double in adolescent males and females who underwent gastric bypass surgery versus those who underwent adjustable gastric band surgery. Bariatric surgery can safely and substantially reduce weight and related co-morbidities in morbidly obese adolescents for ≥1 year.

Nutrition related problems are increasing worldwide but they have scarcely been evaluated in people with neuromotor disabilities, particularly in developing countries. In this study our aim was to describe the weight-based nutritional diagnoses of children and adolescents with neuromotor disabilities who attended a private rehabilitation center in Mexico City. Data from the first visit's clinical records of 410 patients who attended the Nutrition department at the Teleton Center for Children Rehabilitation, between 1999 and 2008, were analyzed. Sex, age, weight and height, length or segmental length data were collected and used to obtain the nutritional diagnosis based on international growth charts, as well as disability-specific charts. Weight for height was considered the main indicator. Cerebral palsy was the most frequent diagnosis, followed by spina bifida, muscular dystrophy, and Down's syndrome. Children with cerebral palsy showed a higher risk of presenting low weight/undernutrition (LW/UN) than children with other disabilities, which was three times higher in females. In contrast, children with spina bifida, particularly males, were more likely to be overweight/obese (OW/OB), especially after the age of 6 and even more after 11. Patients with muscular dystrophy showed a significantly lower risk of LW/UN than patients with other disabilities. In patients with Down's syndrome neither LW/UN nor OW/OB were different between age and sex. This is the first study that provides evidence of the nutritional situation of children and adolescents with neuromotor disabilities in Mexico, based on their weight status. Low weight and obesity affect a large number of these patients due to their disability, age and sex. Early nutritional diagnosis must be considered an essential component in the treatment of these patients to prevent obesity and malnutrition, and improve their quality of life.

Individuals seeking weight loss treatment have diverse pretreatment weight trajectories, and once enrolled, individuals' response to weight loss treatments also varies greatly and may be influenced by the presence of binge-eating disorder (BED). Reported average weight losses may obscure these considerable differences. This study examined whether BED status and different weight-related change variables are associated with successful weight loss treatment outcomes in a controlled treatment study. Participants (N = 89) with overweight/obesity, with and without BED, participated in a 3-month weight loss trial in primary care with 3- and 12-month follow-ups. We tested the prognostic significance of four weight-related change variables (the last supper, early weight loss, pretreatment weight trajectory, weight suppression) on outcomes (weight loss-overall, weight loss-"subsequent," weight loss during second half of treatment). Early weight loss was positively associated with weight loss-overall at post-treatment, and at 3-month and 12-month follow-up. Early weight loss was positively associated with weight loss-subsequent at post-treatment only. No other weight-related variables were significantly associated with weight loss. Models including BED status and treatment condition were not significant. Participants with early weight loss were more likely to continue losing weight, regardless of BED status or treatment condition. The results highlight the importance of early dedication to weight loss treatment to increase the likelihood of positive outcomes. © 2018 Wiley Periodicals, Inc.

The rate of overweight people amongst schizophrenia sufferers is higher than it is in the general population and this is true even prior to starting drug treatment. It is well known that anti-psychotic medications increase the severity of weight control problems. It seems that weight gain is even more significant in adolescents than in adults. The mechanisms in those medications which cause weight gain are not well understood. Hormones like Leptin, Ghrelin and others are being investigated in relation to this issue. Various interventions, like weight loss medications, were investigated in adults suffering from schizophrenia but not in adolescents. Other weight loss interventions, for example behavior therapy, were also investigated in adults, both as preventive measures and as treatment for already present excessive weight. Even caloric limitation was attempted in closed adult wards. The majority of studies show that there is only a small loss of weight and the patients maintain their high Body Mass Index (BMI). Among adolescents suffering from schizophrenia it was found that weight gain results mostly from increase in caloric intake. The easy availability of processed foods and their relatively low cost, result in the positive caloric balance. During adolescence there is increased sensitivity to outer appearance, however, those youngsters have great difficulty following professionals' advice for a balanced diet. This is particularly hard for those adolescents who are treated with antipsychotics and suffer from increased appetite. In a comparative study of various weight loss treatments for children it was found that the most efficient one is group weight loss clinics intended strictly for parents. The efficacy of such group weight loss clinics for parents of schizophrenia suffering adolescents should also be investigated.

boys. Bullying involvement during adolescence is associated with weight loss preoccupation. Bullies are likely driven by a desire to increase attractiveness and social status; whereas weight loss preoccupation in bullied adolescents may have maladaptive influences on diet and exercise behaviours due to its association with reduced psychological functioning. Future research should consider peer victimisation as a potential modifiable risk factor for reduced psychological functioning and weight loss preoccupation, which if targeted, may help to prevent maladaptive diet and exercise behaviours.

Full Text Available Due to the scale up of antiretroviral therapy, increasing numbers of HIV-infected children are living into adolescence. As these children grow and surpass the immediate threat of death, the issue of informing them of their HIV status arises. This study aimed to understand how perinatally-infected adolescents learn about their HIV-status as well as to examine their preferences for the disclosure process.In-depth interviews were conducted with 31 (14 male, 17 female perinatally-infected adolescents aged 16-20 at an HIV clinic in Harare, Zimbabwe, and focused on adolescents' experiences of disclosure. In addition, 15 (1 male, 14 female healthcare workers participated in two focus groups that were centred on healthcare workers' practices surrounding disclosure in the clinic. Purposive sampling was used to recruit participants. A coding frame was developed and major themes were extracted using grounded theory methods.Healthcare workers encouraged caregivers to initiate disclosure in the home environment. However, many adolescents preferred disclosure to take place in the presence of healthcare workers at the clinic because it gave them access to accurate information as well as an environment that made test results seem more credible. Adolescents learned more specific information about living with an HIV-positive status and the meaning of that status from shared experiences among peers at the clinic.HIV-status disclosure to adolescents is distinct from disclosure to younger children and requires tailored, age-appropriate guidelines. Disclosure to this age group in a healthcare setting may help overcome some of the barriers associated with caregivers disclosing in the home environment and make the HIV status seem more credible to an adolescent. The study also highlights the value of peer support among adolescents, which could help reduce the burden of psychosocial care on caregivers and healthcare workers.

To evaluate the nutritional status of schoolchildren, resident in a semiarid region in the Northeastern Brazil. This is a cross-sectional study, involving 860 children and adolescents aged from 5-19 years-old, enrolled in three public schools in the county. The selection of schools was non-probabilistic type and unintentional. The initial population, which integrated the database, was composed by 1,035 children and teenagers, and 175 students (16.9%) were excluded because of inconsistency in the anthropometric data, resulting in a sample of 860 students. The following outcomes were considered: stunting (malnutrition), overweight and obesity (overweight), being the height/age and body mass index/age (BMI/Age), indices respectively used. Children and adolescents with height <-2 standard deviations and overweight and obese weight z score ≥1 were considered stunted. The statistical analysis was descriptive. The prevalence of stunting and overweight/obesity was 9.1% and 24.0%, respectively. Overweight and stunting were higher in adolescents aged 15 and over, compared to other age groups analyzed. In relation to gender, malnutrition presented itself in a similar way, but overweight was more frequent among females. The results revealed that excess weight, here represented by the sum of overweight and obesity, was more prevalent than stunting (malnutrition), highlighting the urgent need for attention to this problem in order to design interventions capable of contributing to the improvement of schoolchildren nutritional status.

To examine the relationship of body weight to satisfaction with care in adolescents, and to obtain qualitative data on preferences for general and weight-related medical care in normal weight and overweight adolescents. The Weight and its Relationship to Adolescent Perceptions of their Providers survey, a 4-page questionnaire containing previously validated satisfaction scales and open-ended qualitative questions regarding health care preferences, was administered to 62 severely overweight (body mass index [BMI] 38.9 +/- 8.4 kg/m2) and 29 normal weight (BMI 22.5 +/- 4.0 kg/m2) adolescents (age 13.9 +/- 1.7 years; 57% female; 50% Caucasian, 47% African-American, 3% Hispanic). The affective subscale of the medical satisfaction scale was negatively correlated with BMI standard deviation score (r = -.22, p teens. Seventy-nine percent of overweight adolescents stated their health care provider discussed their weight with them; however, only 41% of overweight adolescents desired to discuss their weight. Compared to normal-weight adolescents, overweight teens were more likely to report that their provider raised topics of weight (p teens expressed concerns regarding the public location of their provider's office scale. Satisfaction with affective aspects of the provider-patient relationship is negatively correlated with BMI standard deviation score. Length of experience with one's provider is also a strong predictor of teen satisfaction with their medical care. Teens prefer the term "overweight" for those with high body weight. Sensitivity to confidentiality, privacy, and embarrassment regarding physical examination and weight are important for teen satisfaction.

Seventy-nine percent of overweight adolescents stated their health care provider discussed their weight with them; however, only 41% of overweight adolescents desired to discuss their weight. Compared to normal-weight adolescents, overweight teens were more likely to report that their provider raised topics of weight (p teens expressed concerns regarding the public location of their provider’s office scale. Conclusions Satisfaction with affective aspects of the provider-patient relationship is negatively correlated with BMI standard deviation score. Length of experience with one’s provider is also a strong predictor of teen satisfaction with their medical care. Teens prefer the term “overweight” for those with high body weight. Sensitivity to confidentiality, privacy, and embarrassment regarding physical examination and weight are important for teen satisfaction. PMID:16026727

A study among 1,881 adolescents (52.3% girls) with a mean age of 19.1 years examined the effects of parental social status upon intrasexual competitiveness. Whereas females were consistently more intrasexually competitive the higher the socio-economic status of their parents, males with parents of the lowest socio-economic status tended to be more intrasexually competitive than those with parents of medium socio-economic status, and nearly as intrasexually competitive as those with parents of high socio-economic status. Only among adolescents with parents of low socio-economic status were males more intrasexually competitive than females. Among males and females, higher levels of intrasexual competitiveness were related to a higher family income, to a higher occupational status of the father as well as of the mother, and to a higher educational level of the mother. Only among females were higher levels of intrasexual competitiveness associated with a higher educational level of the father. Males whose fathers had only elementary education had a relatively high level of intrasexual competitiveness. The results are discussed in the context of the multifaceted nature of human status, and the potential relevance of intrasexual competitiveness for individuals of high versus low social status.
Full Text Available The purpose of the study was to examine the physical self-concept and self-esteem in adolescent girls aged between 13 and 18 years in relation to their body mass status. The Slovenian version of the Self-Description Questionnaire (PSDQ was used to determine the multidimensional physical self-concept among participants. The results indicated that overweight girls reported greater body dissatisfaction in terms self-perceived body fat and physical appearance compared to normal-weight girls. Overweight girls also achieved significantly lower scores in the self-perceived physical abilities, as well as global physical-self and self-esteem than normal-weight peers. As expected, underweight girls reported the lowest amount of body fat. Moreover, they reported lower levels of physical activity than normal-weight peers and had less physical strength compared to the other body mass index categories. The findings has significant implications for the work with adolescent girls in terms of developing appropriate educational intervention and physical education programmes aimed towards reinforcing and increasing self-esteem and promoting active lifestyle.

Objective This study examined parenting variables (communication, monitoring) as moderators of a family-based intervention for reducing sedentary behavior (SB) in African American adolescents. As a secondary aim, a similar model was tested using adolescent weight status as the outcome. Methods African American adolescents (n = 73; 12.45 ± 1.45 years; 60% girls; 63% overweight/obese) and caregivers were randomized to a 6-week interactive, parent-based intervention or general health condition. Parent–adolescent communication and monitoring of health behaviors were self-reported by parents. Adolescent SB was self-reported by youth. Results There was a significant intervention by communication interaction, such that intervention families with more positive communication showed lower adolescent SB than those with less positive communication or those in the comparison condition. No effects were found for monitoring on SB or for the model with weight status as the outcome. Conclusions Parent–adolescent communication may be an effective component to integrate into health promotion programs for African American adolescents. PMID:23685450
This study aimed to assess the prevalence of overweight misperception, unhealthy diet practices, and factors associated with these weight-related behaviors among Korean adolescents. The subjects were a nationally representative sample of non-overweight students (52,515 in 2005, 64,084 in 2006, and 67,113 in 2007) in middle and high schools who completed the Korea Youth Risk Behavior Web-Based Survey. The prevalence of weight-related behaviors and factors associated with these behaviors were assessed using a complex sampling design. Of non-overweight students, 14.9% of boys and 22.2% of girls reported their weight as overweight/obese. Dieting within the last year was reported by 19.8% of boys and 41.8% of girls. Of those who attempted dieting, 17.1% of boys and 24.6% of girls indicated practicing at least one unhealthy diet behavior within the last month. Overweight misperceptions were independently associated with diet attempts and unhealthy diets after adjustment for weight status, and demographic, social, and psychological factors. Additionally, these weight-related behaviors were also associated with psychosocial factors such as low school achievement, sadness, suicidal ideation, increased stress perception, and cigarette or alcohol use. In conclusion, the high prevalence of inappropriate weight-related behaviors suggests a need for comprehensive approaches to improve weight-related behaviors in non-overweight Korean adolescents.

Abnormal anthropometry including comparably lower weight and body mass index (BMI) in the adolescent idiopathic scoliosis (AIS) population is increasingly recognised, however, no study has examined postoperative weight loss or its clinical relevance in these relatively thin patients. This study aimed to assess perioperative nutritional status as well as clinically severe involuntary weight loss and its impact on outcomes in patients with AIS undergoing posterior spinal fusion (PSF). A further objective was to compare preoperative anthropometric measurements of the current AIS cohort with healthy controls.

To evaluate the impact of a multidisciplinary clinic on weight management among adolescents with PCOS. 140 adolescent females were evaluated in a multidisciplinary PCOS clinic from March 2005 to December 2008. The team included a pediatric endocrinologist, health psychologist, dietitian, and pediatric gynecologist. 110 were diagnosed with PCOS based on the Rotterdam Criteria. Height, weight, BMI, number of subspecialists seen, use of metformin, and compliance with return visits were obtained from medical records. American Family Children's Hospital in Madison, Wisconsin. 110 adolescent females with polycystic ovary syndrome. Consultation with a dietitian and health psychologist. Change in weight. The average age at first visit was 15.9 years. The average BMI was 34.7 kg/m(2) (range 18.1-55.5). Seventy-six percent had an initial BMI above the 95(th) percentile. Interactions with providers at the initial visit included a pediatric endocrinologist (100%), health psychologist (60.9%), dietitian (75.5%) and gynecologist (70.9%). Seventy one percent returned for a follow-up visit, (average time of 4.5 months between visits) with 57% achieving weight loss (average 3.5 kg) and an additional 12.6% demonstrating no significant weight gain (weight loss/stabilization. In this multidisciplinary clinic for adolescents with PCOS, nearly 70% of patients succeeded in short-term weight stabilization, with 57% demonstrating weight loss. Interactions with the health psychologist and dietitian appeared to play a key role in successful weight control, supporting the importance of psychology and nutrition expertise in the management of this disorder.

Obese African American women under-appraise their body mass index (BMI) classification and report fewer weight loss attempts than women who accurately appraise their weight status. This cross-sectional study examined whether physician-informed weight status could predict weight self-perception and weight self-regulation strategies in obese women. A convenience sample of 118 low-income women completed a survey assessing demographic characteristics, comorbidities, weight self-perception, and weight self-regulation strategies. BMI was calculated during nurse triage. Binary logistic regression models were performed to test hypotheses. The odds of obese accurate appraisers having been informed about their weight status were six times greater than those of under-appraisers. The odds of those using an "approach" self-regulation strategy having been physician-informed were four times greater compared with those using an "avoidance" strategy. Physicians are uniquely positioned to influence accurate weight self-perception and adaptive weight self-regulation strategies in underserved women, reducing their risk for obesity-related morbidity.

The literature on colorectal cancer (CRC screening is contradictory regarding the impact of weight status on CRC screening. This study was intended to determine if CRC screening rates among 2005 National Health Interview Survey (NHIS respondent racial/ethnic and gender subgroups were influenced by weight status. Methods. Univariable and multivariable logistic regression analyses were performed to determine if CRC screening use differed significantly among obese, overweight, and normal-weight individuals in race/ethnic and gender subgroups. Results. Multivariable analyses showed that CRC screening rates did not differ significantly for individuals within these subgroups who were obese or overweight as compared to their normal-weight peers. Conclusion. Weight status does not contribute to disparities in CRC screening in race/ethnicity and gender subgroups.

Different pathways likely underlie the association between early weight gain and cardiovascular disease risk. We examined whether birth weight for length relationship and weight gain up to 2 years of age are associated with lipid profiles and blood pressure (BP) in early adolescence and determined whether childhood adiposity mediates these associations. Data from QUALITY (Quebec Adipose and Lifestyle Investigation in Youth), a cohort of white children with parental history of obesity, were analyzed (n=395). Sex-specific weight for length z scores from birth to 2 years were computed. Rate of postnatal weight gain was estimated using individual slopes of weight for length z -score measurements. Percentage of body fat was measured at 8 to 10 years. Fasting lipids and BP were measured at 10 to 12 years. Using path analysis, we found indirect effects of postnatal weight gain, through childhood adiposity, on all outcomes: Rate of postnatal weight for length gain was positively associated with childhood adiposity, which in turn was associated with unfavorable lipid and BP levels in early adolescence. In contrast, small beneficial direct effects on diastolic BP z scores, independent of weight at other time points, were found for birth weight for length (β=-0.05, 95% CI, -0.09 to -0.002) and for postnatal weight gain (β=-0.02, 95% CI, -0.03 to -0.002). Among children with at least 1 obese parent, faster postnatal weight gain leads to cardiovascular risk factors in early adolescence through its effect on childhood adiposity. Although heavier newborns may have lower BP in early adolescence, this protective direct effect could be offset by a deleterious indirect effect linking birth weight to later adiposity. © 2017 The Authors.

Full Text Available Objectives. To explore if self-perceived overweight in normal weight adolescents influence their weight development into young adulthood and if so, whether physical activity moderates this association. Methods. A longitudinal study of 1196 normal weight adolescents (13–19 yrs who were followed up as young adults (24–30 yrs in the HUNT study. Lifestyle and health issues were assessed employing questionnaires, and standardized anthropometric measurements were taken. Chi square calculations and regression analyses were performed to investigate the associations between self-perceived overweight and change in BMI or waist circumference (WC adjusted for age, age squared, sex, and other relevant cofactors. Results. Adolescents, defined as being normal weight, but who perceived themselves as overweight had a larger weight gain into young adulthood than adolescents who perceived themselves as normal weight (difference in BMI: 0.66 units [CI95%: 0.1, 1.2] and in WC: 3.46 cm [CI95%: 1.8, 5.1]. Level of physical activity was not found to moderate this association. Conclusions. This study reveals that self-perceived overweight during adolescence may affect development of weight from adolescence into young adulthood. This highlights the importance of also focusing on body image in public health interventions against obesity, favouring a “healthy” body weight taking into account natural differences in body shapes.

This research examines the impact of a nutrition education intervention program on the nutritional status and knowledge of Nicaraguan adolescent girls. Anthropometric measurements, hemoglobin values, and data concerning nutritional knowledge were collected from adolescent girls living in Managua, Nicaragua. Using a pre-test/post-test design, data are compared prior to and after the nutrition intervention program. When using Mexican American reference data, statistically significant differences in height-for-age z-scores and weight-for-age z-scores were found when comparing the entire sample of baseline data with data collected after three years of the nutrition intervention program (p nutritional knowledge (p hemoglobin data revealed a significant decrease which may be due to specific environmental factors and pubertal changes. This research has implications concerning the development of successful adolescent focused nutrition intervention programs in Nicaragua, and examines the possibility that catch-up growth occurs during adolescence.

Attempts to obtain the ideal body shape portrayed in advertising can result in behaviors that lead to an unhealthy reduction in weight. This study was designed to identify contributing factors that may be effective in changing the behavior of a sample of Iranian adolescents. Three hundred fifty adolescent girls from high schools in Kerman, Iran participated in a cross-sectional study based on a self-administered questionnaire. Multifactorial logistic regression modeling was used to identify the factors influencing each of the contributing factors for body management methods, and a decision tree model was constructed to identify individuals who were more or less likely to change their body shape. Approximately one-third of the adolescent girls had attempted dieting, and 37 % of them had exercised to lose weight. The logistic regression model showed that pressure from their mother and the media; father's education level; and body mass index (BMI) were important factors in dieting. BMI and perceived pressure from the media were risk factors for attempting exercise. BMI and perceived pressure from relatives, particularly mothers, and the media were important factors in attempts by adolescent girls to lose weight.
Full Text Available Abstract Background Unhealthy weight control behaviours (UWCB among adolescents have significant health and weight consequences. The current longitudinal study aimed to identify personal and socio-environmental predictors of initiation or persistence of adolescent UWCB, in order to inform development of programs aimed at both preventing and stopping UWCB. Methods A diverse sample included 1106 boys and 1362 girls from 31 middle schools and high schools in the United States who were enrolled in Project EAT (Eating Among Teens. Project EAT explored personal, behavioural, and socio-environmental factors associated with dietary intake and body weight in adolescence. Participants completed questionnaires to assess demographics, UWCB (including several methods of food restriction, purging by vomiting or medications, smoking to control weight, or food substitutions and personal and socio-environmental variables at two time points, five years apart, between 1998 and 2004. Logistic regression models examined personal and socio-environmental predictors of initiation and persistence of UWCB among Project EAT participants. Results Results indicate that 15.5% of boys and 19.7% of girls initiated UWCB by Time 2, and 15.9% of boys and 43.3% of girls persisted with these behaviours from Time 1 to Time 2. After controlling for race/ethnicity and weight status changes between assessments, logistic regression models indicated that similar factors and patterns of factors were associated significantly with initiation and persistence of UWCB. For both boys and girls, personal factors had more predictive value than socio-environmental factors (Initiation models: for boys: R2 = 0.35 for personal vs. 0.27 for socio-environmental factors; for girls, R2 = 0.46 for personal vs. 0.26 for socio-environmental factors. Persistence models: for boys: R2 = 0.53 for personal vs. 0.33 for socio-environmental factors; for girls, R2 = 0.41 for personal vs. 0.19 for socio

Lifestyle and disease patterns in Malaysia have changed following rapid economic development. It is important to find out how these changes have affected the nutritional status and health behaviour of the population, especially school children and adolescents. Therefore a survey on school children's and adolescents' health behaviours and perception in Kuala Lumpur was initiated. This paper only reports the observed body mass status of the school children. A total of 3620 school children were selected in this survey using the method of multi-stage sampling. The students were surveyed using pre-tested questionnaires while weight and height were measured by the research team in the field. Using the cut-off of BMI-for-age >or= 95th percentile and students and 14.8% of underweight students. When analysed by gender; 7.5% of boys and 7.1% girls were overweight, while 16.2% of the boys and 13.3% of the girls were underweight. The youngest age group (11 years old) had the highest prevalence of underweight as well as overweight. With increasing age, the prevalence of underweight and overweight decreased and more children were in the normal weight range. The overall prevalence of overweight among the three ethnic groups was similar. However the prevalence of underweight was highest among the Indian students (24.9%), followed by Malays (18.9%) and Chinese (9.5%) (P Malaysia. The promotion of healthy eating and physical activities is required to address the problems of under- and over-nutrition in order to build up a strong and healthy nation in the future.

To propose a simple correction of body-mass index (BMI) based on self-reported weight and height (reported BMI) using gender, body shape perception and socioeconomic status in an adolescent population. 341 boys and girls aged 17-18 years were randomly selected from a representative sample of 2165 French adolescents living in Paris surveyed in 2010. After an anonymous self-administered pen-and-paper questionnaire asking for height, weight, body shape perception (feeling too thin, about the right weight or too fat) and socioeconomic status, subjects were measured and weighed. BMI categories were computed according to Cole's cut-offs. Reported BMIs were corrected using linear regressions and ROC analyses and checked with cross-validation and multiple imputations to handle missing values. Agreement between actual and corrected BMI values was estimated with Kappa indexes and Intraclass correlation coefficients (ICC). On average, BMIs were underreported, especially among girls. Kappa indexes between actual and reported BMI were low, especially for girls: 0.56 95%CI = [0.42-0.70] for boys and 0.45 95%CI = [0.30-0.60] for girls. The regression of reported BMI by gender and body shape perception gave the most balanced results for both genders: the Kappa and ICC obtained were 0.63 95%CI = [0.50-0.76] and 0.67, 95%CI = [0.58-0.74] for boys; 0.65 95%CI = [0.52-0.78] and 0.74, 95%CI = [0.66-0.81] for girls. The regression of reported BMI by gender and socioeconomic status led to similar corrections while the ROC analyses were inaccurate. Using body shape perception, or socioeconomic status and gender is a promising way of correcting BMI in self-administered questionnaires, especially for girls.

To describe the weight status and weight-related behaviors of children commencing school. This study is a representative cross-sectional survey of Australian children in their first year of schooling (n=1141) in 2010. Height and weight were measured, and parents reported their child's diet, physical activity and screen-time. 18.7% of children were overweight/obese. Compared with non-overweight/obese peers, overweight/obese boys were 1.73 times (95% CI 1.08, 2.79) as likely to exceed recommended screen time and 2.07 times (95% CI 1.11, 3.87) as likely to eat dinner three or more times/week in front of the TV. Overweight/obese girls were twice as likely to have a TV in their bedroom (OR 2.00, 95% CI 1.12, 3.59) and usually be rewarded with sweets for good behavior (OR 1.96, 95% CI 1.09, 3.51) and were 1.65 times as likely to be inactive (95% CI 1.08, 2.55). We showed that many children begin school with established weight-related behaviors that occur in the home environment. The inclusion of parents and the home environment in intervention strategies will be important to support changes to reduce childhood obesity. The weight status and weight-related behaviors of children entering school may potentially be a general indicator of the overall effectiveness of obesity prevention interventions among preschool-aged children.

The current impact of adolescent obesity on educational attainment is not clear. The objectives of our study were to determine whether adolescent obesity is associated with college degree attainment and how this association may have changed over time. We used data from a contemporary national cohort of over 4,000 persons who were adolescents (aged 14-18) in 1997 to assess the relationship between adolescent obesity and education. To assess for changes in this relationship over time, we also analyzed an older, similarly structured cohort of over 3,000 persons who were adolescents (aged 16-18) in 1981. Our primary outcome was college degree completion. We found that in the older cohort (adolescents in 1979), there were no differences in college degree attainment by adolescent weight status before and after adjustment. However, unadjusted analysis of the contemporary cohort (adolescents in 1997) demonstrated that those who were normal weight as adolescents had a higher prevalence of college degree attainment at follow-up compared to obese adolescents (24% vs. 10%). After adjustment for socio-demographic variables (age, sex, race, height, parental income-to-poverty ratio, parental education, aptitude test scores), obese adolescents were less likely to have attained a college degree compared to normal weight peers (adjusted risk ratio 0.61 95% confidence interval 0.38-0.83). Expectations for a future college degree did not vary by weight status and did not explain this observation. In conclusion, adolescent obesity is associated with lower likelihood of college completion. This relationship was not observed in an older cohort of adolescents.

Ethnic minority adolescents, Hispanics in particular, are disproportionately affected by extreme obesity and its associated co-morbidities. Bariatric surgery is one of the few effective treatments for morbid obesity, yet little information about weight outcomes after surgery in this demographic are available. We determined the effectiveness of bariatric surgery in reducing weight and body mass index (BMI) in adolescents, a majority of whom were non-Mexican American Hispanic and originated from Central and/or South America and the Caribbean Basin region. Adolescents (16-to-19 years old) who had undergone gastric bypass or adjustable gastric band surgery between 2001 and 2010 and who had complete follow-up data available (91 %) were included in the analysis. Mean weight and BMI before and 1-year after surgery were compared. Among 71 adolescents (80 % Hispanic, 77 % female), mean BMI and weight, and z-scores and percentile transformations were all significantly lower after surgery for the entire sample (P surgery showed significantly better weight loss outcomes for all anthropometric measures versus adjustable gastric band surgery (P surgery. Our results show that bariatric surgery, gastric bypass procedure in particular, can markedly reduce weight among a predominantly Hispanic adolescent patient sample. These findings indicate that bariatric surgery has the potential to be safe and effective in substantially reducing weight in a group of adolescents who are at a particularly high risk for obesity-related health consequences.

We investigated changes in cardiorespiratory performance, BMI and leisure-time physical activity among Finnish adolescents from 2003 to 2010. In addition, we compared cardiorespiratory performance levels between normal weight and overweight adolescents, grouped according to their physical activity. Participants were a national representative samples of 15-16-year-old adolescents in their final (ninth) year of comprehensive school in 2003 (n = 2258) and in 2010 (n = 1301). They performed an endurance shuttle run test and reported their height and weight and leisure time physical activity on a questionnaire. Results showed no significant secular changes in cardiorespiratory performance from 2003 to 2010. The mean BMI increased in boys. Leisure-time physical activity increased among normal weight girls. Adolescents of normal weight had better cardiorespiratory performance than those classified as overweight at both assessment points. BMI-adjusted physical activity was a significant determinant for cardiorespiratory performance among overweight adolescents, and very active overweight adolescents had similar cardiorespiratory performance levels as moderately active adolescents of normal weight. The results of the present study support the idea that the physical activity has the great importance for the cardiorespiratory performance in adolescents. Overweight adolescents, in particular, benefit from higher levels of physical activity.
The purpose of the study was to examine the physical self-concept and self-esteem in adolescent girls aged between 13 and 18 years in relation to their body mass status.

It has been established that health professionals' smoking and physical activity influence their related health-promoting behaviours, but it is unclear whether health professionals' weight status also influences their related professional practices. A systematic review was conducted to understand the relationship between personal weight status and weight management practices. Nine eligible studies were identified from a search of the Cochrane Library, MEDLINE, EMBASE, PsycINFO, CINAHL and Chinese databases. All included studies were cross-sectional surveys employing self-reported questionnaires. Weight management practice variables studied were classified under six practice indicators, developed from weight management guidelines. Syntheses of the findings from the selected studies suggest that: normal weight doctors and nurses were more likely than those who were overweight to use strategies to prevent obesity in-patients, and, also, provide overweight or obese patients with general advice to achieve weight loss. Doctors' and nurses' own weight status was not found to be significantly related to their referral and assessment of overweight or obese patients, and associations with their relevant knowledge/skills and specific treatment behaviours were inconsistent. Additionally, in female, primary care providers, relevant knowledge and training, self-efficacy and a clear professional identity emerged as positive predictors of weight management practices. This review's findings will need to be confirmed by prospective theoretically driven studies, which employ objective measures of weight status and weight management practices and involve multivariate analyses to identify the relative contribution of weight status to weight management. © 2011 The Authors. obesity reviews © 2011 International Association for the Study of Obesity.

Parenting style and parental support and modeling of physical activity and healthy dietary intake have been linked to youth weight status, although findings have been inconsistent across studies. Furthermore, little is known about how these factors co-occur, and the influence of the coexistence of these factors on adolescents' weight. This article examines the relationship between the co-occurrence of various parenting characteristics and adolescents' weight status. Data are from Project EAT (eating among teens), a population-based study of 4,746 diverse adolescents. Theoretical and latent class groupings of parenting styles and parenting practices were created. Regression analyses examined the relationship between the created variables and adolescents' BMI. Having an authoritarian mother was associated with higher BMI in sons. The co-occurrence of an authoritarian mother and neglectful father was associated with higher BMI for sons. Daughters' whose fathers did not model or encourage healthy behaviors reported higher BMIs. The co-occurrence of neither parent modeling healthy behaviors was associated with higher BMIs for sons, and incongruent parental modeling and encouraging of healthy behaviors was associated with higher BMIs in daughters. Although, further research into the complex dynamics of the home environment is needed, findings indicate that authoritarian parenting style is associated with higher adolescent weight status and incongruent parenting styles and practices between mothers and fathers are associated with higher adolescent weight status.

This study described the nutritional status of 228 pregnant women and the influence of this on birth weight. This is a retrospective study, developed in a health center in the municipality of São Paulo, with data obtained from medical records. Linear regression analysis was carried out. An association was verified between the initial and final nutritional status (ppregnancy underweight was higher compared those who started overweight/obese (p=0.005). Weight gain was insufficient for 43.4% of the pregnant women with adequate initial weight and for 36.4% of all the pregnant women studied. However, 37.1% of those who began the pregnancy overweight/obese finished with excessive weight gain, a condition that ultimately affected almost a quarter of the pregnant women. Anemia and low birth weight were uncommon, however, in the linear regression analysis, birth weight was associated with weight gain (pimportance of nutritional care before and during pregnancy to promote maternal-infant health.
Full Text Available Background. Prevalence of the metabolic syndrome is increasing in pediatric age groups worldwide. Meeting the criteria for the metabolic syndrome puts children at risk for later cardiovascular and metabolic disease. Methods. Using linear regression, we examined the association between infant weight gain from birth to 3 months and risk for the metabolic syndrome among 16- to 17-year-old Chilean adolescents (n=357, accounting for the extent of breastfeeding in infancy and known covariates including gender, birth weight, and socioeconomic status. Results. Participants were approximately half male (51%, born at 40 weeks of gestation weighing 3.5 kg, and 48% were exclusively breastfed for ≥90 days. Factors independently associated with increased risk of metabolic syndrome in adolescence were faster weight gain in the first 3 months of life (B=0.16, P<0.05 and male gender (B=0.24, P<0.05. Breastfeeding as the sole source of milk for ≥90 days was associated with significantly decreased risk of metabolic syndrome (B=−0.16. Conclusion. This study adds to current knowledge about early infant growth and breastfeeding and their long-term health effects.
Full Text Available Previous researchers have described the relation between physical self-concept and body mass in adolescents, but those relationships have not been clearly specified by gender. The purpose of this study is to explore physical self-concepts of normal-weight and over-weight Serbian adolescents with respect to gender. The sample consisted of 417 primary school students (229 boys and 188 girls with the average age 13.6 (SD=0.73 years who were divided into normal-weight and overweight groups according to body mass index. To assess the multidimensional physical self-concept, Physical Self-Description Questionnaire (PSDQ was administered. Results showed that overweight adolescents had significantly lower scores than normal-weight on all PSDQ scales except Health and Strength. Differences were greater among girls than boys. Discriminant analysis showed that the scales Body Fat, Endurance and Sports Competence best differentiated normal-weight boys from other students. Also, discriminant analysis showed that, besides the scale Body Fat, scales Flexibility, Self-Esteem, and Coordination best differentiated normal-weight girls from other students. Results indicate that for better understanding of the relationship between adolescent’s physical self-concept and body mass one must take gender into account. Results are potentially valuable for preventing overweight through physical education.

Full Text Available Background: Identifying and investigating the factors influencing self-efficacy and eventually health related quality of life (HRQoL can be an important step toward the prevention and treatment of the obesity. The aim of the study was to compare weight self-efficacy and HRQoL among normal-weight, overweight and obese Iranian adolescents. Materials and Methods In this case-control study, 118 obese and overweight adolescents (case group and 118 adolescents with normal weight (control group were recruited. Adolescent's anthropometric characteristics were measured. The Weight Efficacy Lifestyle Questionnaire (WEL, pediatric quality of life inventory (PedsQLTM 4.0 and self-reported physical activity were completed by the adolescents. Results: Multivariate logistic regression adjusting for various confounders indicated that overweight and obese adolescents were less likely to be physically active (adjusted odds ratio, AOR= 0.66; 95% confidence interval [CI], 0.48 to 0.911, had lower ability to cope with social pressure (AOR= 0.54; 95% CI, 0.32 to 0.93, involved in less positive activities (AOR= 0.53; 95% CI, 0.37 to 0.75, and felt more negative emotions (AOR= 0.23; 95% CI, 0.14 to 0.36 than their normal-weight counterparts. Moreover, obese and overweight adolescents were more likely to report deteriorated quality of life in all PedsQL subscales than those with normal weight P
Full Text Available INTRODUCTION: Neuroscience evidence suggests that adolescent obesity is linked to brain dysfunctions associated with enhanced reward and somatosensory processing and reduced impulse control during food processing. Comparatively less is known about the role of more stable brain structural measures and their link to personality traits and neuropsychological factors on the presentation of adolescent obesity. Here we aimed to investigate regional brain anatomy in adolescents with excess weight vs. lean controls. We also aimed to contrast the associations between brain structure and personality and cognitive measures in both groups. METHODS: Fifty-two adolescents (16 with normal weight and 36 with excess weight were scanned using magnetic resonance imaging and completed the Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ, the UPPS-P scale, and the Stroop task. Voxel-based morphometry (VBM was used to assess possible between-group differences in regional gray matter (GM and to measure the putative differences in the way reward and punishment sensitivity, impulsivity and inhibitory control relate to regional GM volumes, which were analyzed using both region of interest (ROI and whole brain analyses. The ROIs included areas involved in reward/somatosensory processing (striatum, somatosensory cortices and motivation/impulse control (hippocampus, prefrontal cortex. RESULTS: Excess weight adolescents showed increased GM volume in the right hippocampus. Voxel-wise volumes of the second somatosensory cortex (SII were correlated with reward sensitivity and positive urgency in lean controls, but this association was missed in excess weight adolescents. Moreover, Stroop performance correlated with dorsolateral prefrontal cortex volumes in controls but not in excess weight adolescents. CONCLUSION: Adolescents with excess weight have structural abnormalities in brain regions associated with somatosensory processing and motivation.
Theories of susceptibility to peer influence have centered on the idea that lower status adolescents are likely to adopt the behaviors of high status adolescents. While status is important, social exchange theorists have shown the value of analyzing exchange relations between actors to understand differences in power. To build on status-based…

Body weight status has been linked to other health parameters. The aim of this study was to evaluate the relationship between body weight status and self-concept in a sample of 216 students (9.26 ± 1.26 years) from schools of the Southeast of Spain. BMI (Body-mass index) was used to evaluate the body weight status. Subjects were classified into normal weight, overweight and obesity according to international standards. The six dimensions of self-concept (intellectual, behavioral, physical, lack of anxiety, social and life satisfaction) were assessed using the Piers-Harris Self-Concept Scale. The results showed significant associations between BMI and intellectual self-concept, life satisfaction, global self-concept and physical self. Subjects categorized as overweight or obese were those who showed lower scores on the self-concept scale. Interventions focused on improving the body weight status are needed in order to achieve better self-concept levels and health among young people. Copyright AULA MEDICA EDICIONES 2014.

Many studies rely on self-reports to capture population trends and trajectories in weight gain over adulthood, but the validity of self-reports is often considered a limitation. The purpose of this work was to examine long-term trajectories of self-reporting bias in a national sample of American youth. With 3 waves of data from the National Longitudinal Study of Adolescent Health (1996-2008), we used growth curve models to examine self-reporting bias in trajectories of weight gain across adolescence and early adulthood (ages 13-32 years). We investigated whether self-reporting bias is constant over time, or whether adolescents become more accurate in reporting their weight as they move into young adulthood, and we examined differences in self-reporting bias by sex, race/ethnicity, and attained education. Adolescent girls underreported their weight by 0.86 kg on average, and this rate of underreporting increased over early adulthood. In contrast, we found no evidence that boys underreported their weight either in adolescence or over the early adult years. For young men, self-reports of weight were unbiased estimates of measured weight among all racial/ethnic and educational subpopulations over adolescence and early adulthood. © The Author 2014.

The natural emergence of status hierarchies in adolescent peer groups has long been assumed to help prevent future intragroup aggression. However, clear evidence of this beneficial influence is lacking. In fact, few studies have examined between-group differences in the degree of status hierarchy (defined as within-group variation in individual status) and how they are related to bullying, a widespread form of aggression in schools. Data from 11,296 eighth- and ninth-graders (mean age = 14.57, 50.6 % female) from 583 classes in 71 schools were used to determine the direction of the association between classroom degree of status hierarchy and bullying behaviors, and to investigate prospective relationships between these two variables over a 6-month period. Multilevel structural equation modeling analyses showed that higher levels of classroom status hierarchy were concurrently associated with higher levels of bullying at the end of the school year. Higher hierarchy in the middle of the school year predicted higher bullying later in the year. No evidence was found to indicate that initial bullying predicted future hierarchy. These findings highlight the importance of a shared balance of power in the classroom for the prevention of bullying among adolescents.

This study was to investigate the relationship between blood pressure, lipids and body mass index by smoking status among adolescents. This study was designed as a descriptive correlational study. General and smoking characteristics were collected using a questionnaire. The smoking group consisted of 42 (33%) students and the non smoking group 85 (67%) students. Blood pressure, lipids, height and weight were measured, and body mass index was calculated to kg/m2. The collected data was analyzed by the n(%), chi2-test, t-test and Pearson correlation coefficient (SPSS 12.0). 1. The smoking level was different between grade, smoking status among the family, the contentment of their relationship with their parents, school life and teachers. 2. The smoking group's systolic blood pressure, total cholesterol, triglyceride, low density lipoprotein cholesterol and body mass index were higher than those of the non smoking group. 3. The smoking amount had a significant positive correlation between total cholesterol and low density lipoprotein cholesterol. The result of this study offered basic data to develop intervention programs to prevent hypertension and hyperlipidemia in smoking adolescents.
This article attempts to establish that socioeconomic status (SES) plays an important role in the lives of adolescents and is reflected in adolescent literature. The emphasis on SES in four adolescent novels: The Outsiders by S.E. Hinton, To Kill a Mockingbird by Harper Lee, The Catcher in the Rye by J. D. Salinger, and The Pigman by Paul Zindel suggests that both the authors and their young readers are aware of its influence in today's society. Three areas which are greatly affected by SES are examined: adolescents' self-esteem, how it affects characterization and subsequently the degree to which adolescents identify with a literary character, and how it functions as a learning device, enabling authors to infuse their own moral values into the minds of their audiences.

Women's lives are marked by complex work and family routines - routines that have implications for their children's health. Prior research suggests a link between mothers' work hours and their children's weight, but few studies investigate the child health implications of increasingly common work arrangements, such as telecommuting and flexible work schedules. We examine whether changes in mothers' work arrangements are associated with changes in adolescents' weight, physical activity, and sedentary behavior using longitudinal data and fixed effects models to better account for mothers' social selection in to different work arrangements and children's underlying preferences. With data from the National Longitudinal Study of Adolescent to Adult Health ( N = 10,518), we find that changes in mothers' work arrangements are not significantly associated with adolescents' weight gain or physical activity but are significantly associated with adolescents' sedentary behavior. Adolescents' sedentary behavior declines when mothers become more available after school and increases when mothers work more hours or become unemployed. In sum, after accounting for unobserved, stable traits, including mothers' selection into jobs with more or less flexibility, mothers' work arrangements are most strongly associated with adolescents' sedentary behavior.

the purpose of the present study was to describe some perinatal outcomes in two groups of pregnant adolescents: one group with history of sexual abuse and one group without sexual abuse antecedent. we designed an observational, retrolective study. Participants were primigravid adolescents between 10 to 16 years, with a singleton pregnancy, and at least three prenatal medical evaluations. Participants were grouped according to sexual abuse antecedent: 55 adolescents had sexual abuse antecedent, and 110 participants had not sexual abuse antecedent. We obtained the clinical data from medical records: socio-demographic characteristics, sexually transmitted infections, illicit drugs use, pre-gestational body mass index, gestational weight gain, and newborn weight. The data were analyzed using association tests and mean comparisons. the adolescents with sexual abuse history had higher prevalence of human papilloma virus infection. The newborns weight of mothers without sexual abuse antecedent was about 200 grams higher than the newborns of mothers with sexual abuse antecedent (p = 0.002); while the length of the first group was 2 centimeters longer than the length of the newborns on the second group (p = 0.001). Gestational weight increase was 5 kilograms lower in adolescents with sexual abuse antecedent compared to adolescent without the antecedent (p = 0.005). Illicit drug use was similar in the two groups and it was associated to low newborn weight. the sexual abuse antecedent in pregnant adolescents was associated to higher frequency of human papilloma virus infections, lower newborn weight, and lower gestational weight increase on pregnant adolescents.

To determine whether increases in adolescent or parental self-efficacy predicted subsequent weight gain in two different therapies for adolescent anorexia nervosa (AN). Participants were 121 adolescents with AN (M = 14.4 years, SD = 1.6), from a two-site randomized clinical trial for family-based treatment (FBT) and individual adolescent focused therapy (AFT). Both adolescent and parental self-efficacy were assessed at baseline and sessions 2, 4, 6, and 8. Adolescent self-efficacy was assessed using a generic measure of self-efficacy, while parental self-efficacy was assessed using a measure specific to the recovery of an eating disorder. Weight was assessed at baseline, sessions 1 through 8, and end of treatment. Mixed-effects models were used to evaluate the relation between patient and parent self-efficacy and subsequent weight gain, controlling for weight at the previous time point. For families who received FBT, greater within-treatment increases in parental self-efficacy predicted greater subsequent adolescent weight gain compared to those who received FBT with lesser change in parental self-efficacy and those who received AFT. Interestingly, adolescent self-efficacy did not significantly predict subsequent weight gain. Greater increases in parental self-efficacy predicted significantly greater subsequent weight gain for adolescents who received FBT, but the same was not true for adolescents who received AFT. Neither overall level nor change in adolescent self-efficacy significantly predicted subsequent weight gain in either treatment group. These findings emphasize the importance of increasing parental self-efficacy in FBT in order to impact adolescent weight outcomes. © 2015 Wiley Periodicals, Inc.

Studies evaluating the relationship between oral health status and obesity have provided conflicting data. Therefore, there is a great need to investigate and clarify the possible connection in a comprehensive sample. To assess the relationship of obesity and oral health status among children and adolescents aged 6 to 17 years-old. Cross-sectional study. Data were obtained from 4,534 children and adolescents (2,018 boys and 2,516 girls). Questionnaires were sent home prior to examination; afterwards, anthropometric and dental data were collected from participants. Community Periodontal Index (CPI) and number of decayed, missing, and filled teeth in the permanent dentition (DMFT), and deciduous dentition (dmft) index were used to measure oral health status. Height, body weight, body mass index (BMI), waist circumference (WC), and body fat percentage were analyzed. For DMFT scores, healthy (score=0) girls and boys had significantly higher BMI and WC values than unhealthy (score>1) girls and boys (pnutritional habits and obesity. Obesity and dental/periodontal diseases are multifactorial diseases that follow similar risk patterns and develop from an interaction between chronic conditions originating early in life. It is important for all health professionals to educate patients at risk about the progression of periodontal and dental diseases and the importance of proper oral hygiene.

The current literature on determinants of behavior change in weight management lacks sufficient studies on type of motivation among children/adolescents, on perceived competence, and in relation to healthy eating. This study aimed to investigate type of motivation and levels of perceived competence for healthy diet and exercise, as well as general self efficacy among adolescents. We hypothesized that overweight/obese adolescents would demonstrate lower autonomous motivation and perceived competence regarding diet and exercise, and lower self-efficacy in general, and that the scores would be influenced by socioeconomic factors. Normal weight ( n = 40, body mass index Competence Scale (PCS) for healthy eating and exercise, and the General Self-Efficacy Scale (GSES). Composite scores for the three scales were compared between the two groups using the using the two-sample t-test (for normal data) or the Mann-Whitney U test (for non-parametric data). Relationships between the composite scores and patient characteristics were determined using Pearson or Spearman's correlations. The average age of the total cohort was 15.9 ± 1.9 years. 54% were female, and 82% identified as Latino/Hispanic. In comparison to normal weight subjects, overweight/obese adolescents exhibited higher scores for controlled motivation (mean ± standard deviation 28.3 ± 9.3 vs 18.1 ± 8.1) and higher perceived competence [median and 25-75% interquartile range 22.5 (19.0-26.0) vs 20.0 (15.5-25.0)] in relation to eating a healthy diet. These differences persisted after adjustment for age, sex, paternal education, and family income. Overweight/obese adolescents did not lack autonomous motivation but demonstrated higher controlled motivation and perceived competence for healthy eating in comparison to normal weight adolescents, independent of socioeconomic factors. In the clinical practice of weight management, providers should carefully assess adolescents for type of

Suicide is a leading cause of death among adolescents globally, and body weight is also a recognized reason for adolescent suicide. Therefore, we investigated the association between weight control behaviors (WCB) and suicide ideation and attempt, focusing on inappropriate weight control measures. We used data from the 2014 Korea Youth Risk Behavior Web-based Survey, representing a total of 35,224 boys and 34,361 girls aged 12 to 18 years. Adolescents were classified into groups based on WCB: appropriate WCB, inappropriate WCB, and no WCB. We performed logistic regression models to examine associations between WCB and suicide ideation and attempt, controlling for covariates. Both boys and girls with inappropriate WCB were more likely to report suicide ideation and attempt. Underweight and normal weight boys with inappropriate WCB were more likely to think or attempt suicide, and underweight girls with inappropriate WCB were also more likely to attempt suicide. Among five common WCB combinations, the combination of "regular exercise, fasting, eating less" was highly associated with suicide ideation and attempt. We confirmed that inappropriate WCB is associated with suicide ideation and attempt among Korean adolescents. Given the high incidence rate of suicide among adolescents and the adverse effect of inappropriate WCB, encouraging adolescents to control their weight in healthy ways is imperative.

To determine how characteristics of pregnancy, birth, and early infancy are related to offspring obesity at three critical developmental periods. Mothers were followed through pregnancy and 10-15 years after. Offspring data were obtained through medical record review. Maternal and offspring characteristics were examined to predict obesity in childhood (ages 4-5 years), adolescence (ages 9-14 years), and early adulthood (ages 19-20 years). The original cohort included 802 children born to 795 women. Children who were twins, who had died, or whose mothers had died were excluded (n=25). Medical records of 68.5% of the remaining 777 children documented a height and weight at childhood, adolescence, or early adulthood. Relative risks (RRs) to predict obesity at early adulthood were 12.3 for childhood and 45.1 at adolescence. RRs were also significant to predict obesity at early adulthood between the mother's obesity at prepregnancy (RR=6.4), 4-5 years postpregnancy (RR=6.3), and 10-15 years postpregnancy (RR=6.2). Excluding these variables from the multivariate models and adjusting by gender, birth insurance, and mother's marital status at delivery, the best model to predict obesity at childhood included birth weight, weight gain in infancy, and delivery type. At adolescence, it included maternal pregnancy smoking status, gestational weight gain, and weight gain in infancy, and in early adulthood, included maternal pregnancy smoking status, gestational weight gain, and birth weight. Maternal pregnancy smoking status, gestational weight gain, and weight gain in infancy have long-term effects on offspring. Maternal obesity is the strongest predictor of obesity at all times studied.

Bariatric surgery produces robust weight loss, however, factors associated with long-term weight-loss maintenance among adolescents undergoing Roux-en-Y gastric bypass surgery are unknown. Fifty adolescents (mean±s.d. age and body mass index (BMI)=17.1±1.7 years and 59±11 kg m -2 ) underwent Roux-en-Y gastric bypass surgery, had follow-up visits at 1 year and at a visit between 5 and 12 years following surgery (Follow-up of Adolescent Bariatric Surgery at 5 Plus years (FABS-5+) visit; mean±s.d. 8.1±1.6 years). A non-surgical comparison group (n=30; mean±s.d. age and BMI=15.3±1.7 years and BMI=52±8 kg m -2 ) was recruited to compare weight trajectories over time. Questionnaires (health-related and eating behaviors, health responsibility, impact of weight on quality of life (QOL), international physical activity questionnaire and dietary habits via surgery guidelines) were administered at the FABS-5+ visit. Post hoc, participants were split into two groups: long-term weight-loss maintainers (n=23; baseline BMI=58.2 kg m -2 ; 1-year BMI=35.8 kg m -2 ; FABS-5+ BMI=34.9 kg m -2 ) and re-gainers (n=27; baseline BMI=59.8 kg m -2 ; 1-year BMI=36.8 kg m -2 ; FABS-5+ BMI=48.0 kg m -2 ) to compare factors which might contribute to differences. Data were analyzed using generalized estimating equations adjusted for age, sex, baseline BMI, baseline diabetes status and length of follow-up. The BMI of the surgical group declined from baseline to 1 year (-38.5±6.9%), which, despite some regain, was largely maintained until FABS-5+ (-29.6±13.9% change). The BMI of the comparison group increased from baseline to the FABS-5+ visit (+10.3±20.6%). When the surgical group was split into maintainers and re-gainers, no differences in weight-related and eating behaviors, health responsibility, physical activity/inactivity, or dietary habits were observed between groups. However, at FABS-5+, maintainers had greater overall QOL scores than re

The objective of this article was to describe the relationship between sociodemographic factors and nutritional status (body mass index [BMI], height for age, and anemia) in adolescents. In 2002, a cross-sectional study comprising 824 students aged 12 to 14 years from 8 schools in 2 prefectures in Jiangsu province of China had their height, weight, and hemoglobin level measured. Self-administered questionnaires were used to collect sociodemographic information. The prevalence of underweight was low in the overall sample (5.2%). The prevalence of stunting also was low (2.9%), and the differences between residential areas and sociodemographic groups were small. The percentage of overweight/obesity was higher among boys (17.9%) than girls (8.9%). Male students having fathers with a high educational level had the highest percentage of overweight and obesity (27.8%). Household socioeconomic status (SES) was associated positively with BMI. Family size, gender, and the father's level of education also were related to BMI. The percentage of anemia was somewhat higher among girls (23.4%) than boys (17.2%). Anemia coexisted with underweight. No urban/rural or SES differences in the percentage of students with anemia were observed in the sample, but differences between regions and schools were very significant. Undernutrition was not a problem in the research area. Nutritional status was associated with SES and region. Overnutrition and anemia in adolescents are important nutritional problems in Jiangsu, China. Intervention programs are needed to address these problems.

To compare weight concerns and self-reported body mass index (BMI) of low birth weight (LBW) adolescent boys to those of a normative sample and examine relationships among BMI, weight concerns, self-esteem, and depression in the LBW cohort. LBW boys (n = 260; mean age, 16.0) belong to the Neonatal Brain Hemorrhage Study birth cohort. Normative boys (n = 305; mean age, 16.5) belong to the National Health and Nutrition Examination Survey. Both samples were assessed in 2001-2004 with self-report questionnaires. BMI was calculated from self-reported height and weight. Weight perception and weight dissatisfaction were assessed with the Eating Symptoms Inventory. In LBW boys, self-esteem was measured with the Rosenberg Self-Esteem Scale and depression with the Beck Depression Inventory. Based on self-reported height and weight, LBW boys were more likely to be healthy weight or underweight and less likely to be overweight than normative boys. Despite having healthier self-reported BMIs, LBW boys reported more weight concerns than the normative sample. A total of 46.9% of LBW boys perceived their weight as abnormal, and 76.5% desired weight change. Weight concerns in LBW boys mostly reflected a perception of being underweight (31.2% of the cohort) and a desire to gain weight (47.5% of the cohort), although only 6.5% were clinically underweight. Weight concerns, but not BMI, were related to clinical depression and lower self-esteem. LBW adolescent boys are at high risk of experiencing weight concerns. Weight concerns rather than BMI are associated with emotional problems in LBW boys.

This study uses a novel mixed methods design to examine the relationship between incidents of teasing in popular television shows and body satisfaction of adolescent viewers. Survey data were used to identify 25 favorite television shows in a large population-based sample of Minnesota adolescents (N=2793, age=14.4years). Data from content analysis of teasing incidents in popular shows were linked to adolescent survey data. Linear regression models examined associations between exposure to on-screen teasing in adolescents' own favorite shows and their body satisfaction. Effect modification by adolescent weight status was tested using interaction terms. Teasing on TV was common, with 3.3 incidents per episode; over one-quarter of teasing was weight/shape-related. Exposure to weight/shape-related teasing (β=-0.43, p=0.008) and teasing with overweight targets (β=-0.03, p=0.02) was inversely associated with girls' body satisfaction; no associations were found for boys. Findings were similar regardless of the adolescent viewer's weight status. Families, health care providers, media literacy programs and the entertainment industry are encouraged to consider the negative effects exposure to weight stigmatization can have on adolescent girls.

While overweight and obese children are more likely to have overweight or obese parents, less is known about the effect of parental weight status on children's success in weight management programmes. This study was a secondary data analysis of a randomized controlled trial and investigated the impact of having zero, one or two obese parents on children's success in a school-based weight management programme. Sixty-one Mexican-American children participated in a 24-week school-based weight management intervention which took place in 2005-2006. Children's heights and weights were measured at baseline, 3, 6 and 12 months. Parental weight status was assessed at baseline. Repeated measures anova and ancova were conducted to compare changes in children's weight within and between groups, respectively. Within-group comparisons revealed that the intervention led to significant decreases in standardized body mass index (zBMI) for children with zero (F = 23.16, P weight management programme appears to be most efficacious for children with one or no obese parents compared to children with two obese parents. These results demonstrate the need to consider parental weight status when engaging in childhood weight management efforts. © 2015 World Obesity.

Full Text Available Objective: To analyze the sleep characteristics in adolescents from different socioeconomic levels. Data source: Original studies found in the MEDLINE/PubMed and SciELO databases without language and period restrictions that analyzed associations between sleep variables and socioeconomic indicators. The initial search resulted in 99 articles. After reading the titles and abstracts and following inclusion and exclusion criteria, 12 articles with outcomes that included associations between sleep variables (disorders, duration, quality and socioeconomic status (ethnicity, family income, and social status were analyzed. Data synthesis: The studies associating sleep with socioeconomic variables are recent, published mainly after the year 2000. Half of the selected studies were performed with young Americans, and only one with Brazilian adolescents. Regarding ethnic differences, the studies do not have uniform conclusions. The main associations found were between sleep variables and family income or parental educational level, showing a trend among poor, low social status adolescents to manifest low duration, poor quality of sleeping patterns. Conclusions: The study found an association between socioeconomic indicators and quality of sleep in adolescents. Low socioeconomic status reflects a worse subjective perception of sleep quality, shorter duration, and greater daytime sleepiness. Considering the influence of sleep on physical and cognitive development and on the learning capacity of young individuals, the literature on the subject is scarce. There is a need for further research on sleep in different realities of the Brazilian population.

To compare the effects of a hypocaloric low-fat diet with those of a very low carbohydrate diet on body mass index (BMI), waist circumference (WC), and menstrual function in overweight adolescent females with polycystic ovary syndrome (PCOS). Randomized pilot trial of two diets in a prospective, 12-week study. A hospital-based, academic adolescent medicine division. 24 females, age 12-22 years (mean 15.8 ± 2.2), with PCOS and a BMI above the 85(th) percentile for age (mean 35.7 ± 6.0 kg/m(2)). Nutrition counseling was given biweekly, and dietary compliance, menstrual history, and weight were recorded. WC was measured at the beginning and end of the study. Changes in weight, BMI, WC, and improvement in menstrual function over the course of the study period. 16 participants completed the study. 12 completers menstruated during the study period, 8 with regularity. The number of periods over 3 months increased from 0.6 ± 0.6 pre-treatment to 1.6 ± 1.3 post-treatment (P = 0.003). Overall, weight loss averaged 6.5% (P weight were 3.4 times more likely to have improved menstrual function (P = 0.001). There were no statistically significant differences between the two groups. Weight loss is feasible in adolescents with PCOS and results in significant improvements in BMI, WC, and menstrual function. Weight management may be preferable as first-line treatment in adolescents, because it targets both the menstrual dysfunction and risk factors for long-term morbidity associated with PCOS.

In the present study the relation between overweight/obesity and health-related quality of life (HRQoL) in adolescence is analysed. Of special interest is the question, to what extent this relation varies by socio-economic status (SES) and education. Data base is a subsample of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS, n = 6,813, 11-17 years). For the assessment of overweight and obesity, body mass index (BMI) was calculated based on standardised body height and weight measurements. The HRQoL was collected using the KINDL-R-questionnaire, which allows statements concerning a total rating as well as 6 dimensions: physical well-being, emotional well-being, self-worth, family well-being, well-being in relation to friends/peers and school well-being. SES and education are analysed as moderating factors. The results show that obese boys as well as overweight and obese girls have a diminished HRQoL compared to normal weight peers. The analyses according to SES and education suggest that in girls this finding applies for all considered subgroups. Thus, in girls neither SES nor education has a moderating impact on the relation between overweight/obesity and HRQoL. In boys, only SES has a moderating impact on the relation between overweight and HRQoL in favour of the low status group. In terms of the relation between obesity and HRQoL, in boys also only SES has a moderating impact on the analysed relation, but here in favour of the high status group. Altogether, the results show that overweight and especially obese adolescents are affected in their HRQoL, this being almost independent of SES and education. Interventions to improve the HRQoL of overweight and obese adolescents should be independent of SES and education.

School attendance can impact academic performance. Childhood obesity-related physical and psychosocial consequences are potentially associated with school absenteeism. Thus, we examined the association between school absenteeism attributed to illness or injury and obesity among adolescents aged 12-17 years. We used a weighted sample of 3,470 U.S. adolescents from the 2009 National Health Interview Survey. School absenteeism was measured from the parent-reported number of sick days taken in the preceding 12 months. Body mass index was calculated from parent-reported weight and height. Weight status was classified based on the sex-specific body mass index-for-age percentile defined by the CDC growth charts. Poisson regression was conducted to examine the association between school absenteeism and weight status, controlling for selected sociodemographic characteristics and disease status. The mean number of annual sick days was 3.9 days overall; 3.4 days among normal-weight, 4.4 days among overweight, and 4.5 days among obese adolescents. Obese adolescents had a higher proportion of missing ≥4 days of school per year than adolescents of normal weight. Our multivariate analyses found that compared with adolescents of normal weight, overweight and obese adolescents had greater than one-third more sick days annually (rate ratio = 1.36 for overweight and 1.37 for obese adolescents). Overweight and obese adolescents had 36% and 37% more sick days, respectively, than adolescents of normal weight. The results suggest another potential aspect of obesity prevention and reduction efforts among children and families is to improve children's school attendance. Published by Elsevier Inc.

Limited data are available on the characteristics of adolescents with obesity who seek bariatric surgery. Existing data suggest that adolescent surgery candidates have a higher body mass index (BMI) than comparison adolescents with obesity, but the limited findings regarding psychosocial functioning are mixed. This study aimed to compare BMI and psychosocial functioning among adolescent bariatric surgery candidates, outpatient medical-treatment-seeking adolescents with obesity (receiving lifestyle modification), and adolescents in the normal-weight range. All adolescents completed self-report measures of impulsivity, delay discounting, depression, anxiety, stress, eating pathology, family functioning and quality of life, and had their height and weight measured. Adolescent surgical candidates had higher BMIs than both comparison groups. Surgical candidates did not differ from medical-treatment-seeking adolescents with obesity on any measure of psychosocial functioning, but both groups of adolescents with obesity reported greater anxiety and eating pathology and poorer quality of life than normal-weight adolescents. Quality of life no longer differed across groups after controlling for BMI, suggesting that it is highly related to weight status. Adolescents with obesity may experience greater anxiety, eating pathology, and quality of life impairments than their peers in the normal-weight range regardless of whether they are seeking surgery or outpatient medical treatment. Clinical implications and directions for future research are discussed. © 2017 World Obesity Federation.

Research to date in young children and adults shows a strong, inverse relationship between sleep duration and risk for overweight and obesity. Fewer studies examining this relationship have been conducted in adolescents. The purpose of the article is to describe the relationship between sleep and weight in a population of adolescents, controlling for demographics, energy intake, energy expenditure, and depression. This is a cross-sectional study of 723 adolescents participating in population-...
Full Text Available Abstract Background Amount of sleep is an important indicator of health and well-being in children and adolescents. Adequate sleep (AS: adequate sleep is defined as 6–8 hours per night regularly is a critical factor in adolescent health and health-related behaviors. The present study was based on a health promotion project previously conducted on adolescents in Tao-Yuan County, Taiwan. The aim was to examine the relationship between AS during schooldays and excessive body weight, frequency of visiting doctors and health-related behaviors among Taiwanese adolescents. Methods A cross-sectional study design, categorical and multivariate data analyses were used. The hypotheses investigated were: high frequency of AS is positively associated with lack of obesity and less frequent visits to doctors; and high frequency AS is positively associated with health-related behavior. Results A total of 656 boys (53.2% and girls (46.8%, ranging in age from 13–18 years were studied between January and June 2004. Three hundred and fifty seven subjects (54% reported that they slept less than the suggested 6–8 hours on schooldays. A significant negative association was found between low sleep and of the following health-related behaviors: (1 life appreciation; (2 taking responsibility for health; (3 adopting healthy diet; (4 effective stress management; (5 regular exercise; and (6 total AHP score. High frequency AS was associated with low frequencies of obesity after potential confounding factors were controlled. Junior high school adolescents reported significantly higher frequencies of AS than high school participants. Gender, family structure, home location and frequency of television watching or computer use were not significantly associated with AS. Conclusion These findings support the proposition that AS is associated with good health status and high-frequency adoption of health-related behavior. Furthermore, these findings suggest that inadequate

Research conducted with adults suggests that successful weight losers demonstrate greater activation in brain regions associated with executive control in response to viewing high-energy foods. No previous studies have examined these associations in adolescents. Functional neuroimaging was used to assess brain response to food images among groups of overweight (OW), normal-weight (NW), and successful weight-losing (SWL) adolescents. Eleven SWL, 12 NW, and 11 OW participants underwent functional magnetic resonance imaging while viewing images of high- and low-energy foods. When viewing high-energy food images, SWLs demonstrated greater activation in the dorsolateral prefrontal cortex (DLPFC) compared with OW and NW controls. Compared with NW and SWL groups, OW individuals demonstrated greater activation in the ventral striatum and anterior cingulate in response to food images. Adolescent SWLs demonstrated greater neural activation in the DLPFC compared with OW/NW controls when viewing high-energy food stimuli, which may indicate enhanced executive control. OW individuals' brain responses to food stimuli may indicate greater reward incentive processes than either SWL or NW groups. © 2015 The Obesity Society.

This study examined the degree to which sex, weight status, and the presence of hypertension and obesity in parents/grandparents were associated with systolic (SBP) and diastolic (DBP) blood pressure (BP) among African American youth in a pilot offspring study examining obesity-related cardiovascular disease (CVD) risks among adolescents. Fully adjusted linear regression models of the total sample produced results indicating that obesity was associated with BP (SBP: β = 7.08, P obesity were associated with SBP (overweight: β = 6.77, P obese: β = 11.65, P obesity was correlated with DBP (β = 9.86, P obesity was associated with DBP (β = 6.98, P obesity was significantly associated with SBP among adolescent females but not males. The relationship between weight status, familial hypertension and obesity status, and BP among adolescents vary by sex. This study underscores the need for additional research investigating the relationship between individual sex, weight status, BP and familial BP, and obesity status on risk among African American adolescents. © American Journal of Hypertension, Ltd 2017.

Bangladesh has a high prevalence of adolescent pregnancy, but little is known about the nutritional status and dietary practices of Bangladeshi adolescents in early pregnancy or associated factors. We used the baseline data of 1552 pregnant adolescents from a longitudinal, cluster-randomized effectiveness trial conducted in northwest Bangladesh. Forty-four percent of the adolescents were short for their age, 36% had low body mass index, 28% were anemic, 10% had iron deficiency, and 32% had vitamin A deficiency. The mean consumption of animal-source foods was 10.3 times/week. In multivariate analysis, socioeconomic status, education, and food security were generally positively associated with anthropometric indicators and dietary practices but not with iron or vitamin A status. Our findings confirm that there is a high burden of undernutrition among these Bangladeshi adolescents in early pregnancy. Understanding factors related to undernutrition can help to identify adolescent pregnant women at higher risk and provide appropriate counseling and care. © 2018 New York Academy of Sciences.

The objective of this study was to investigate the relationship between metabolic syndrome and its individual components with socio-economic factors among 14-18 year-old adolescents in Shiraz, Iran. Using a multistage random sampling, a total of 538 (289 males and 249 females) adolescents consented to the study. Socio-economic status was obtained using a self-administered questionnaire while presence of metabolic syndrome and its individual components was ascertained using NCEP-ATP III criteria. The relationships between the participants' socio-economic status and metabolic syndrome and its components were determined using bivariate and multivariate statistical analyses. Approximately 6% of the adolescents had metabolic syndrome, with significantly more males than females (9.3% vs 2.4%, p Metabolic syndrome was significantly more prevalent in obese participants (44.4%) than those with normal body weight (2.0%) or overweight (9.3%). There were positive associations between the components of metabolic syndrome and parental education, school location and household monthly income. Having a family history of obesity was associated with metabolic syndrome after controlling for other variables (OR = 2.1; 95% CI: 0.9-5.2, p = 0.042). Overweight and obese subjects were approximately 8 times and 15 times more likely to develop metabolic syndrome, respectively (overweight: OR = 8.2; 95% CI: 3.6-17.2; obese: OR = 15.4; 95% CI: 4.8-43.7). In conclusion, a positive association exists between socio-economic status and metabolic syndrome and its individual components among the studied participants. An intervention program to prevent metabolic syndrome needs to be developed for this young generation, especially among those who are overweight or obese and those with a family history of obesity.

Mothers' feeding practices are associated with their children's weight status, but little is known about the associations between fathers' feeding practices and children's weight status. Moreover, there is a dearth of research on Latino fathers' feeding practices and children's weight status, even though Latino children suffer some of the highest obesity rates in the U.S. We examined the associations between fathers' feeding practices and child weight status, conditional on mothers' feeding practices, within 174 Mexican American families with children aged 8-10 years. Parents completed the Parental Feeding Practices Questionnaire, which consists of four subscales: positive involvement in child eating, pressure to eat, use of food to control behavior, and restriction of amount of food. To assess child weight status, body mass index (BMI) was calculated and converted to age- and gender-specific percentile scores (BMI z-score). We fit four sets of regression models, one set for each of the four parental feeding practices subscales, with child BMI z-score as the outcome variable. Fathers' pressure to eat (b = -0.20, p = 0.04; 95% CI: -0.39, -0.01) and use of food to control behavior (b = -0.36, p = 0.02; 95% CI: -0.65, -0.07) were associated with lower child BMI z-score, and restriction of amount of food (b = 0.56, p Fathers' positive involvement in child eating was not associated with child BMI z-score. These findings provide empirical evidence that fathers' feeding practices are independently associated with children's weight status, even when mothers' feeding practices are taken into account, and suggest that fathers' feeding practices also matter in regard to children's weight status.

Pre-prepared commercial foods (convenience foods, CFs) are one aspect of modern dietary habits. The present paper examines the association between CF consumption and dietary quality or body weight status in a sample of German children and adolescents. Linear mixed-effect regression analyses using data from 586 participants (296 boys, 3-18 years) in the Dortmund Nutritional Anthropometric Longitudinally Designed Study, who yearly completed 1890 3-day dietary records and anthropometric measurements in 2004-2008, was used. CF intake (percent total food intake) showed no significant association with macronutrient intakes (%E), with exception of a significant positive association with polyunsaturated fatty acid (PUFA) intake (Ptrend with increased consumption of CF (P=0.0013). No significant association between baseline or change in consumption of CF and baseline or change in parameters of body weight (standard deviation score of body mass index (weight/height(2)) or percentage body fat (%BF) estimated from skinfolds) was found. Among boys, baseline consumption of high-ED-CF significantly predicted change in %BF during the study period (β 0.104, P=0.0098). Our results point to an impairment of dietary quality with high consumption of CF and to a small but positive association between consumption of high-ED-CF in boys and weight.

To examine eating habits and energy and nutrient intake among adolescents participating in weight-related and power team sports and non-sport-involved adolescents. Data were drawn from Project EAT (Eating Among Teens), which was conducted with 4,746 adolescents from 31 middle and high schools in the Minneapolis/St Paul metropolitan area. Urban secondary schools. Adolescents reporting participation in a weight-related sport, a power team sport, or no consistent participation in a sport. Meal and snack frequency, mean energy and nutrient intake, and mean physical activity. Analyses were conducted by sex across the three groups. General linear models were used to compare mean energy and nutrient intake, composite nutrient adequacy, and mean physical activity across the three groups. Percentages of youth meeting nutrient recommendations were compared across the three groups using chi(2) tests. For both males and females, youth involved in weight-related sports ate breakfast more frequently than non-sport-involved peers (females: 3.6 and 3.2 times per week, respectively, Psport-involved youth also had higher mean protein, calcium, iron, and zinc intakes than non-sport-involved peers. However, adolescent females had low calcium intake, regardless of sports involvement (weight-related sports 1,091 mg/day, power team sports 1,070 mg/day, and non-sport-involved 1,028 mg/day, PSport-involved adolescents have better eating habits and nutrient intake than their non-sport-involved peers. However, they are still in need of nutrition interventions, particularly around calcium intake.

The aim of this study was to determine whether treated, weight-stabilized adolescents with anorexia nervosa (AN) present brain volume differences in comparison with healthy controls. Thirty-five adolescents with weight-recovered AN and 17 healthy controls were assessed by means of psychopathology scales and magnetic resonance imaging. Axial three-dimensional T1-weighted images were obtained in a 1.5 Tesla scanner and analyzed using optimized voxel-based morphometry (VBM). There were no significant differences between controls and weight-stabilized AN patients with regard to global volumes of either gray or white brain matter, or in the regional VBM study. Differences were not significant between patients with psychopharmacological treatment and without, between those with amenorrhea and without, as well as between patients with restrictive versus purgative AN. The present findings reveal no global or regional gray or white matter abnormalities in this sample of adolescents following weight restoration. Copyright © 2013 Wiley Periodicals, Inc.

Full Text Available Asian American children and adolescents are an under-investigated subpopulation in obesity research. This study aimed to identify specific profiles of Asian subgroups at high risk of adolescent overweight with special attention to Asian ethnicity, socioeconomic status (SES, and their interaction. Multiple logistic regression models were fitted using a sample of 1533 Asian American adolescents ages 12–17 from the 2007–2012 California Health Interview Survey (CHIS. In addition to Asian ethnicity and socioeconomic status (assessed by family income and parental education level, age, gender, nativity, and two lifestyle variables, fast food consumption and physical activity, were also controlled for in these models. Key predictors of overweight in Asian American adolescents included certain Asian ethnicities (Southeast Asian, Filipino, and mixed ethnicities, low family income (<300% of the Federal Poverty Level, and being male. Multiplicative interaction terms between low family income and two ethnicities, Southeast Asian and Vietnamese that had the lowest SES among Asian ethnic groups, were significantly associated with greatly elevated odds of being overweight (ORs = 12.90 and 6.67, respectively. These findings suggest that high risk of overweight in Asian American adolescents associated with low family incomes may be further elevated for those in low-income ethnic groups. Future research might investigate ethnic-group SES as a meaningful indicator of community-level socioeconomic disparities that influence the health of Asian Americans.

The increasing prevalence of obesity among youth has elicited calls for schools to become more active in promoting healthy weight. The present study examined associations between various aspects of school food environments (specifically the availability of snack- and beverage-vending machines and the presence of snack and beverage logos) and students' weight status, as well as potential influences of indices of diet and food behaviours. A cross-sectional, self-administered web-based survey. A series of multinomial logistic regressions with generalized estimating equations (GEE) were constructed to examine associations between school environment variables (i.e. the reported presence of beverage- and snack-vending machines and logos) and self-reported weight- and diet-related behaviours. Secondary schools in Alberta, Canada. A total of 4936 students from grades 7 to 10. The presence of beverage-vending machines in schools was associated with the weight status of students. The presence of snack-vending machines and logos was associated with students' frequency of consuming vended goods. The presence of snack-vending machines and logos was associated with the frequency of salty snack consumption. The reported presence of snack- and beverage-vending machines and logos in schools is related to some indices of weight status, diet and meal behaviours but not to others. The present study supported the general hypothesis that the presence of vending machines in schools may affect students' weight through increased consumption of vended goods, but notes that the frequency of 'junk' food consumption does not seem to be related to the presence of vending machines, perhaps reflecting the ubiquity of these foods in the daily lives of students.

To examine education differences in five-year weight change among mid-aged adults, and to ascertain if this may be due to socioeconomic differences in perceived weight status or weight control behaviours (WCBs). Data were used from the Australian Diabetes, Obesity and Lifestyle Study. Mid-aged men and women with measured weights at both baseline (1999-2000) and follow-up (2004-2005) were included. Percent weight change over the five-year interval was calculated and perceived weight status, WCBs and highest attained education were collected at baseline. Low-educated men and women were more likely to be obese at baseline compared to their high-educated counterparts. Women with a certificate-level education had a greater five-year weight gain than those with a bachelor degree or higher. Perceived weight status or WCBs did not differ by education among men and women, however participants that perceived themselves as very overweight had less weight gain than those perceiving themselves as underweight or normal weight. WCBs were not associated with five-year weight change. The higher prevalence of overweight/obesity among low-educated women may be a consequence of greater weight gain in mid-adulthood. Education inequalities in overweight/obesity among men and women made be due (in part) to overweight or obese individuals in low-educated groups not perceiving themselves as having a weight problem. © 2011 The Authors.

Adolescent obesity is increasingly viewed as a brain-related dysfunction, whereby reward-driven urges for pleasurable foods "hijack" response selection systems, such that behavioral control progressively shifts from impulsivity to compulsivity. In this study, we aimed to examine the link between personality factors (sensitivity to reward (SR) and punishment (SP), BMI, and outcome measures of impulsivity vs. flexibility in--otherwise healthy--excessive weight adolescents. Sixty-three adolescents (aged 12-17) classified as obese (n = 26), overweight (n = 16), or normal weight (n = 21) participated in the study. We used psychometric assessments of the SR and SP motivational systems, impulsivity (using the UPPS-P scale), and neurocognitive measures with discriminant validity to dissociate inhibition vs. flexibility deficits (using the process-approach version of the Stroop test). We tested the relative contribution of age, SR/SP, and BMI on estimates of impulsivity and inhibition vs. switching performance using multistep hierarchical regression models. BMI significantly predicted elevations in emotion-driven impulsivity (positive and negative urgency) and inferior flexibility performance in adolescents with excess weight--exceeding the predictive capacity of SR and SP. SR was the main predictor of elevations in sensation seeking and lack of premeditation. These findings demonstrate that increases in BMI are specifically associated with elevations in emotion-driven impulsivity and cognitive inflexibility, supporting a dimensional path in which adolescents with excess weight increase their proneness to overindulge when under strong affective states, and their difficulties to switch or reverse habitual behavioral patterns.

Pediatric obesity is a growing public health concern that contributes to high rates of negative long-term physical and mental health outcomes. Research focused on identifying risk for pediatric obesity has linked delay discounting, or an inclination for immediate rewards, as well as weight concern to individuals with greater Body Mass Index (BMI). The current study seeks to fill a void in the literature by examining how these two variables interact to promote higher BMI in female adolescents. Adolescent (n=60) females between the ages of 13-19years (mage=17.45, SD=1.74) of age completed the Eating Disorder Examination Questionnaire (EDE-Q) and the Delay Discounting Questionnaire. A mediation model examined whether delay discounting accounted for the relationship between weight concern and BMI. Results indicate that in the current study weight concern was negatively related to delay discounting and delay discounting was negatively related to BMI. The overall model revealed that a partial mediation occurred [b=1.28, t(60)=4.92, pconcerns contribute to greater BMI. Nevertheless, the results indicate that prevention and interventions should identify females with high levels of both weight concern and impulsivity as an increased risk for experiencing pediatric obesity and long-term negative health outcomes.

Obsession with thinness and body dissatisfaction can lead adolescents to follow unsupervised diets, which could result in risky weight control behaviors such as fasting, vomiting, use of diuretics and laxatives. The aim of the current study is to examine weight control behaviors in dieting adolescents and relate them to body dissatisfaction (BD) and obsession with thinness (OT). A cross-sectional study was conducted on 439 adolescents from Valparaiso public schools to investigate risky weight control behaviors due to BD and OT scales from the Eating Disorders Inventory-2 (EDI-2), comparing restrained eaters and non-restrained eaters. A total of 43% adolescents had followed a weight loss diet without medical supervision. The dieters had higher BD and OT values. Moderate to severe food restriction, based on expert judgment, was observed in 29.6%, and differences in the presence and severity of purging behaviors were found between the 2 groups. One third of the adolescents studied followed diets without professional supervision and had higher BD and OT values, as well as risky weight control behaviors. Overweight and obese adolescents followed more restrictive diets and developed riskier weight control behaviors. Copyright © 2015. Publicado por Elsevier España, S.L.U.

In contrast to the extensive knowledge on the association between women's empowerment and the nutritional status of children under the age of five, relatively little is known about the influence of women's empowerment on adolescents' nutritional status. This study aimed to assess the association between women's empowerment and gender inequalities in adolescent nutritional status. Data were from the Indonesian Family Life Survey (IFLS) covering the period 1997 to 2015, and consisted of 16,683 observations from 13,396 adolescents between the ages of 10 and 19 years born in 6781 families. Three indicators of women's empowerment were used: mother's education, mother's bargaining power and mother's working status. Multivariate linear regression with robust standard errors was used to examine whether and how these indicators of women's empowerment influenced adolescent nutritional status. Interaction terms were added to analyse how the association between women's empowerment and adolescent nutritional status differed by gender. The results showed that mother's education and mother's working status were significantly associated with adolescent nutritional status, particularly with height-for-age. Adolescents of well-educated mothers had a higher height-for-age while those who were raised by mothers with a blue-collar job had a lower height-for-age. Although no gender differences were found for height-for-age, gender differences for BMI-for-age were obvious, with boys having a lower BMI-for-age than girls. Interactions between indicators of mother's empowerment and gender showed that the gender gap in BMI-for-age was smaller for adolescents of more educated mothers. However, further analyses of food consumption patterns showed that boys whose mothers were more educated consumed more fast food and had higher instant noodle consumption than girls, thus suggesting gender bias in new disguise.

This study evaluates accuracy of self-reported weight in adolescent bariatric surgery patients. During follow-up visits, participants self-reported weight and had weight measured. The differences between self-reported and measured weights were analyzed from 60 participants. Participants were 70% (n = 42) female, 72% (n = 43) white, mean age of 20.8 years and a median body mass index of 36.6 kg/m 2 . At an average of 3.5 years following surgery, females underestimated weight (0.5 kg, range: -18.7 to 5.6 kg), while males overestimated (1.1 kg, range: -7.8 to 15.2 kg). Most (80%, n = 48) reported within 5 kg of measured weight. The majority of adolescents who previously underwent bariatric surgery reported reasonably accurate weights, but direction of misreporting varied by gender. Self-reported weights could be utilized when measured values are unavailable without markedly biasing the interpretation of outcomes.
The objective of the study was to determine the dietary intake and nutritional status of adolescent girls (n=156) and young women students (n=367) in Durban, KwaZulu Natal (KZN), South Africa. No national prevalence rates for stunting, wasting and underweight could be found for adolescent girls in South Africa and the ...

To investigate dysfunctional eating behaviors and psychological variables typically associated to eating disturbances such as low self-esteem, perfectionism, shame, perceived parental care and protectiveness in obese and normal weight adolescents and to examine how the main powerful eating disorder risk factors interact with each other which explains eating psychopathology vulnerability. 111 high school students (68 males; age range 13-19years) classified as obese and 111 age-, sex- and social status-homogeneous normal weight controls were included in the current study. All participants were asked to fill out self-report measures of parental behavior as perceived by the offspring, eating disturbance attitudes and behaviors, self-esteem, perfectionism and shame. Significant differences between the two groups in relation to dysfunctional eating behaviors emerged. Body shame had the strongest relationship to eating problems vulnerability and acted as a mediator in the relationship between low self-esteem and eating disorder risk among both obese and non-obese youngsters. These findings further our understanding of a potential underlying mechanism for eating pathology development in youngsters in general and in obese adolescents in particular, which is of great importance in terms of prevention and treatment.

It is important to update weight-for-length/height growth curves in China and re-examine their performance in screening malnutrition. To develop weight-for-length/height growth curves for Chinese children and adolescents. A total of 94 302 children aged 0-19 years with complete sex, age, weight and length/height data were obtained from two cross-sectional large-scaled national surveys in China. Weight-for-length/height growth curves were constructed using the LMS method before and after average spermarcheal/menarcheal ages, respectively. Screening performance in prevalence estimates of wasting, overweight and obesity was compared between weight-for-height and body mass index (BMI) criteria based on a test population of 21 416 children aged 3-18. The smoothed weight-for-length percentiles and Z-scores growth curves with length 46-110 cm for both sexes and weight-for-height with height 70-180 cm for boys and 70-170 cm for girls were established. The weight-for-height and BMI-for-age had strong correlation in screening wasting, overweight and obesity in each age-sex group. There was no striking difference in prevalence estimates of wasting, overweight and obesity between two indicators except for obesity prevalence at ages 6-11. This set of smoothed weight-for-length/height growth curves may be useful in assessing nutritional status from infants to post-pubertal adolescents.

To document the prevalence of harassment on the basis of weight, race/ethnicity, and socioeconomic status, as well as sexual harassment, among a diverse population of adolescents. Specifically, this study examined rates of each type of harassment reported across groups within the corresponding sociodemographic category (e.g., racial/ethnic category differences in prevalence of racial harassment), and also explored patterns of "cross-harassment" (i.e., differences in prevalence of each harassment type across all other sociodemographic characteristics). We used data from Project Eating and Activity in Teens 2010 for the study. The sample was composed of 2,793 adolescents (53% female; 81% nonwhite). We conducted regression analyses to yield prevalence estimates of each type of harassment in each demographic and body mass index category. Weight- and race-based harassment (35.3% and 35.2%, respectively) was most prevalent, followed by sexual harassment (25.0%) and socioeconomic status-based harassment (16.1%). Overweight and obese adolescents reported disproportionately higher rates of all forms of harassment than did normal-weight and underweight adolescents. In addition, Asian and mixed-/other race adolescents were more vulnerable to harassment overall compared with those from other racial/ethnic groups. Harassment experiences are prevalent among adolescent boys and girls. Differential rates of each type of harassment are reported across groups within the corresponding sociodemographic category, but a pattern of cross-harassment also is evident, such that differences in prevalence of each type of harassment emerge across a variety of sociodemographic characteristics. Adolescents from various intersecting sociodemographic and weight-status groups are particularly vulnerable to certain types of harassment.

Most peer influence research examines socialization between adolescents and their best friends. Yet, adolescents also are influenced by popular peers, perhaps due to misperceptions of social norms. This research examined the extent to which out-group and in-group adolescents misperceive the frequencies of peers' deviant, health risk, and adaptive behaviors in different reputation-based peer crowds (Study 1) and the prospective associations between perceptions of high status peers' and adolescents' own substance use over 2.5 years (Study 2). Study 1 examined 235 adolescents' reported deviant (vandalism, theft), health risk (substance use, sexual risk), and adaptive (exercise, studying) behavior, and their perceptions of Jocks', Populars', Burnouts', and Brains' engagement in the same behaviors. Peer nominations identified adolescents in each peer crowd. Jocks and Populars were rated as higher status than Brains and Burnouts. Results indicated that peer crowd stereotypes are caricatures. Misperceptions of high status crowds were dramatic, but for many behaviors, no differences between Populars'/Jocks' and others' actual reported behaviors were revealed. Study 2 assessed 166 adolescents' substance use and their perceptions of popular peers' (i.e., peers high in peer perceived popularity) substance use. Parallel process latent growth analyses revealed that higher perceptions of popular peers' substance use in Grade 9 (intercept) significantly predicted steeper increases in adolescents' own substance use from Grade 9 to 11 (slope). Results from both studies, utilizing different methods, offer evidence to suggest that adolescents misperceive high status peers' risk behaviors, and these misperceptions may predict adolescents' own risk behavior engagement.

Objectives. To explore if self-perceived overweight in normal weight adolescents influence their weight development into young adulthood and if so, whether physical activity moderates this association. Methods. A longitudinal study of 1196 normal weight adolescents (13–19 yrs) who were followed up as young adults (24–30 yrs) in the HUNT study. Lifestyle and health issues were assessed employing questionnaires, and standardized anthropometric measurements were taken. Chi square calculations an...

Full Text Available Failure to consume an adequate diet or over consumption during adolescence can disrupt normal growth and development, resulting in undesirable weight change. This leads to an increase in unhealthy weight control practices related to eating and exercise among both adolescent girls and boys to meet the societal 'ideal' body shape. This study therefore aims to examine the longitudinal changes in eating attitudes, body-esteem and weight control behaviours among adolescents between 13 and 17 years; and, to describe perceptions around body shape at age 17 years. A total of 1435 urban South African black and mixed ancestry boys and girls, who had data at both age 13 and 17 years from the Birth to Twenty cohort were included. Data were collected through self-administered questionnaires on eating attitudes (EAT-26, body esteem and weight control behaviours for either weight loss or muscle gain attempts. Height and weight were measured at both time points and BMI was calculated. Black females had a higher BMI (p<0.001 and an increased risk of developing eating disorders as well as significant increase in the prevalence of weight loss practices between the ages 13 and 17 years. At age 17 years both Mixed ancestry adolescents had lower body-esteem compared to black adolescents. The prevalence of possible eating disorders was 11% and 13.1% in early and late adolescents respectively. Males and females shared similar opinions on normal silhouettes being the 'best', 'getting respect' and being the 'happiest', while the obese silhouette was associated with the 'worst' and the 'unhappiest', and the underweight silhouette with the "weakest". Black females had a higher BMI and an increased risk of developing eating disorders. Adolescent females engaged more in weight loss practices whereas, males in muscle gain practices indicating that Western norms of thinness as the ideal are becoming more common in South Africa.

Concerns about social status are ubiquitous during adolescence, with information about social status often conveyed in text formats. Depressed adolescents may show alterations in the functioning of neural systems supporting processing of social status information. We examined whether depressed youth exhibited altered neural activation to social status words in temporal and prefrontal cortical regions thought to be involved in social cognitive processing, and whether this response was associated with development. Forty-nine adolescents (ages 10-18; 35 female), including 20 with major depressive disorder and 29 controls, were scanned while identifying the valence of words that connoted positive and negative social status. Results indicated that depressed youth showed reduced late activation to social status (vs neutral) words in the superior temporal cortex (STC) and medial prefrontal cortex (MPFC); whereas healthy youth did not show any significant differences between word types. Depressed youth also showed reduced late activation in the dorsolateral prefrontal cortex and fusiform gyrus to negative (vs positive) social status words; whereas healthy youth showed the opposite pattern. Finally, age was positively associated with MPFC activation to social status words. Findings suggest that hypoactivation in the "social cognitive brain network" might be implicated in altered interpersonal functioning in adolescent depression. Copyright © 2017 The Authors.

Advances during the past decade have made it feasible to apply e-health methods to chronic disease management. Researchers have recently begun applying these methods to weight control. The application of e-health management methods to weight control in adolescents has yet to be investigated empirically. This study conducted a systematic review of reports discussing the weight-control effects of e-health management in adolescents. Researchers searched 6 electronic databases for relevant articles published between 1995 and April 2013. Data were collected using inclusion and exclusion criteria. A modified Jadad Scale was used to evaluate the quality of the identified articles. Seven studies met the inclusion criterion of targeting adolescent subject populations. A total of 3728 adolescents and 1394 parents participated in these studies. The majority of participants were overweight girls and median participant ages ranged from 12.52 (SD = 3.15) to 15.31 (SD = 0.69). All studies reported that e-health management reduced body mass index and body fat percentage. Four studies indicate that e-health management may improve physical activity knowledge and skills. However, diet control outcomes among the seven studies varied. Empirical results demonstrate that e-health management significantly affects weight control. However, the effectiveness of log-in versus primary outcome indicators was inconclusive. Future studies should consider the use of incentives, reminder systems, and other strategies to enhance website usage. The development of an Internet-based, computer-tailored weight-management intervention for overweight adolescents and the development of an appropriate care model are recommended.

We studied the prevalence and stability of overweight and obesity in a cohort of adolescents, and the effects of sedentary behaviour and physical activity on changes in body mass. The study also examined the extent to which physical activity mediated the relationship between sedentary behaviour and body mass. Four-year cohort study. The study was part of the Health Behaviour of School-aged Children Study that took place in Wales between 1994 and 1998. Body height and weight measurements and self-report data on sedentary behaviour, physical activity and psychosocial adjustment were collected from 355 adolescents on two occasions 4 years apart. The mean age of the sample at baseline was 12.30 (SD=6.30) years. Weight conditions (underweight, overweight and obesity) and body mass were moderately stable over the interval. Regression analyses showed that sedentary behaviour at Time 1 predicted body mass at Time 2, while physical activity predicted a change in body mass over time. The influence of sedentary behaviour on body mass was not found to be mediated by physical activity. However, weight problems in Year 7 coincided with getting bullied, bullying others, and feeling left out of things. Obesity was also related to snacking and skipping breakfast. Sedentary behaviour and physical activity in early adolescence both influenced body mass in late adolescence. Results indicated that promoting healthy diets and physical activities may have long-term health benefits for young people.
Full Text Available Aim: In Korea, obesity is more prevalent among men and lower socioeconomic groups. To explain this obesity disparity, we compared weight perception and weight control behavior across gender and socioeconomic status (SES. Methods: We analyzed data from 16,260 participants aged 20 years or older in a nationally representative cross-sectional survey. SES indicators included education and income levels. Weight under-perception was defined when participants considered themselves lighter than their measured BMI status. Either no active or inappropriate weight control (i.e., trying to gain weight in obese individuals was considered to be unhealthy patterns. Multivariate prevalence ratios were calculated using log-binomial regressions. Results: Men had a higher prevalence of weight under-perception (24.5 vs. 11.9% and unhealthy patterns of weight control behavior (57 vs. 40% than women. Low education level was associated with weight under-perception (ptrend = 0.022 in men, ptrend trend trend = 0.047 in men, ptrend Conclusion: Weight perception and weight control behavior significantly varied by gender and SES. Public actions should be directed toward improving perception and behavior of high-risk populations.
Objectives: This study aimed to determine the prevalence of abnormal eating attitudes and weight-loss behaviour in female Jewish adolescents.

Background The current literature on determinants of behavior change in weight management lacks sufficient studies on type of motivation among children/adolescents, on perceived competence, and in relation to healthy eating. This study aimed to investigate type of motivation and levels of perceived competence for healthy diet and exercise, as well as general self efficacy among adolescents. We hypothesized that overweight/obese adolescents would demonstrate lower autonomous motivation and per...

E-cigarette use among adolescents is on the rise in the U.S. However, limited attention has been given to examining the role of race, citizenship status and language spoken at home in shaping e-cigarette use behavior. Data are from the 2014 Adolescent California Health Interview Survey, which interviewed 1052 adolescents ages 12-17. Lifetime e-cigarette use was examined by sociodemographic characteristics. Separate logistic regression models predicted odds of ever-smoking e-cigarettes from race, citizenship status and language spoken at home. Sociodemographic characteristics were then added to these models as control variables and a model with all three predictors and controls was run. Similar models were run with conventional smoking as an outcome. 10.3% of adolescents ever used e-cigarettes. E-cigarette use was higher among ever-smokers of conventional cigarettes, individuals above 200% of the Federal Poverty Level, US citizens and those who spoke English-only at home. Multivariate analyses demonstrated that citizenship status and language spoken at home were associated with lifetime e-cigarette use, after accounting for control variables. Only citizenship status was associated with e-cigarette use, when controls variables race and language spoken at home were all in the same model. Ever use of e-cigarettes in this study was higher than previously reported national estimates. Action is needed to curb the use of e-cigarettes among adolescents. Differences in lifetime e-cigarette use by citizenship status and language spoken at home suggest that less acculturated individuals use e-cigarettes at lower rates. Copyright © 2016 Elsevier Ltd.

Full Text Available Objective. Klinefelter syndrome (KS has long-term consequences on bone health. However, studies regarding bone status and metabolism during childhood and adolescence are very rare. Patients. This cross-sectional study involved 40 (mean age: 13.7±3.8 years KS children and adolescents and 80 age-matched healthy subjects. For both patient and control groups, we evaluated serum levels of ionised and total calcium, phosphate, total testosterone, luteinising hormone, follicle stimulating hormone, parathyroid hormone (PTH, 25-hydroxyvitamin D (25(OHD, 1,25-dihydroxyvitamin D, osteocalcin, bone alkaline phosphatase, and urinary deoxypyridinoline concentrations. We also calculated the z-scores of the phalangeal amplitude-dependent speed of sound (AD-SoS and the bone transmission time (BTT. Results. KS children and adolescents showed significantly reduced AD-SoS (p<0.005 and BTT (p<0.0005 z-scores compared to the controls. However, KS patients presented significantly higher PTH (p<0.0001 and significantly lower 25(OHD (p<0.0001, osteocalcin (p<0.05, and bone alkaline phosphatase levels (p<0.005. Interestingly, these metabolic bone disorders were already present in the prepubertal subjects. Conclusions. KS children and adolescents exhibited impaired bone mineral status and metabolism with higher PTH levels and a significant reduction of 25-OH-D and bone formation markers. Interestingly, this impairment was already evident in prepubertal KS patients. Follow-ups should be scheduled with KS patients to investigate and ameliorate bone mineral status and metabolism until the prepubertal ages.

Breakfast has been labeled the most important meal of the day, but are there data to support this claim? We summarized the results of 47 studies examining the association of breakfast consumption with nutritional adequacy (nine studies), body weight (16 studies), and academic performance (22 studies) in children and adolescents. Breakfast skipping is highly prevalent in the United States and Europe (10% to 30%), depending on age group, population, and definition. Although the quality of breakfast was variable within and between studies, children who reported eating breakfast on a consistent basis tended to have superior nutritional profiles than their breakfast-skipping peers. Breakfast eaters generally consumed more daily calories yet were less likely to be overweight, although not all studies associated breakfast skipping with overweight. Evidence suggests that breakfast consumption may improve cognitive function related to memory, test grades, and school attendance. Breakfast as part of a healthful diet and lifestyle can positively impact children's health and well-being. Parents should be encouraged to provide breakfast for their children or explore the availability of a school breakfast program. We advocate consumption of a healthful breakfast on a daily basis consisting of a variety of foods, especially high-fiber and nutrient-rich whole grains, fruits, and dairy products.

Executive functioning (EF) problems may serve as vulnerability or maintenance factors for Binge-Eating Disorder (BED). However, it is unclear if EF problems observed in BED are related to overweight status or BED status. The current study extends this literature by examining EF in overweight and normal-weight BED compared to weight-matched controls. Participants were normal-weight women with BED (n = 23), overweight BED (n = 32), overweight healthy controls (n = 48), and normal-weight healthy controls (n = 29). The EF battery utilized tests from the National Institutes of Health (NIH) Toolbox and Delis-Kaplan Executive Function System (D-KEFS). After controlling for years of education and minority status, overweight individuals performed more poorly than normal-weight individuals on a task of cognitive flexibility requiring generativity (p < .01), and speed on psychomotor performance tasks (p = .01). Normal-weight and overweight BED performed worse on working memory tasks compared to controls (p = .04). Unexpectedly, normal-weight BED individuals out-performed all other groups on an inhibitory control task (p < .01). No significant differences were found between the four groups on tasks of planning. Regardless of weight status, BED is associated with working memory problems. Replication of the finding that normal-weight BED is associated with enhanced inhibitory control is needed. © 2017 Wiley Periodicals, Inc.

As the obesity epidemic takes its toll on patients stricken with the disease and our health care system, debate continues regarding the use of weight loss surgery and its long-term consequences, especially for adolescents. One subset of patients regarding whom there is increased controversy is adolescents with extreme obesity (BMI > 60 kg/m(2)) because the risk of complications in this weight category is higher than for others undergoing bariatric surgery. Several strategies have been suggested for this patient group, including staged operations, combined operations, intragastric balloon use, and endoluminal sleeve placement. However, the device options are often not available to adolescents, and there are no data regarding staged or combined procedures in this age group. All adolescents with BMI >60 kg/m(2) referred to our program were evaluated for inpatient medical weight loss prior to laparoscopic sleeve gastrectomy. The program utilizes a multidisciplinary approach with a protein-sparing modified fast diet, exercise, and behavioral modification. Three patients completed the program, and each achieved significant preoperative weight loss through the inpatient program and successfully underwent bariatric surgery. Presurgical weight loss via an inpatient program for adolescents with a BMI >60 kg/m(2) results in total weight loss comparable to a primary surgical procedure alone, with the benefit of decreasing the perioperative risk.
Full Text Available Abstract Background Increases in the prevalence of child and adolescent obesity have accelerated since the mid 1980s. Socio-economic status (SES-adiposity relationships appear less clear in adolescence than childhood, and evidence on whether increasing obesity is itself patterned according to SES is inconsistent. Increasing prevalence may have increased the tolerance, and reduced recognition of, or concern about, obesity. The aim of this study is to report the prevalence of obesity and its association with SES, well-being and worries about weight among 15-year olds in 1987, 1999 and 2006. Methods Height and weight data obtained from 15-year olds in 1987 (N = 503, 1999 (N = 2,145 and 2006 (N = 3,019, allowed categorisation of obesity (UK90 criteria. SES was represented by parental occupational class and area deprivation; psychological wellbeing by the 12-item General Health Questionnaire (GHQ-12 and self-esteem; weight worries by 'a lot' of worry about weight. Results Obesity prevalence was 6.7%, 10.6% and 15.9% (males, and 5.4%, 11.5% and 14.9% (females in 1987, 1999 and 2006. Among obese males, BMIs increased over time. There was little evidence of differentials in obesity in respect of either SES measure, and none for increased disparities over time. There was no association between obesity and GHQ-12 'caseness' or (except females in 2006 self-esteem. Weight worries were more prevalent among the obese and increased over time overall, but the obesity-weight worry relationship did not change. At each date, large proportions of the obese did not worry 'a lot' about weight, while among the non-obese, up to 18.8% males and 40.1% females (in 2006 did worry. Conclusion Between 1987 and 2006, prevalence of obesity among Scottish 15 year olds increased around 2.5 times. However, this increasing prevalence did not impact on the obesity-weight-worry relationship. While many obese adolescents appear unconcerned about their weight, a significant minority

The effect of diet quality on weight change, relative to other body weight determinants, is insufficiently understood. Furthermore, research on long-term weight change in U.S. adults is limited. We evaluated prospectively patterns and predictors of weight change in Framingham Offspring/Spouse (FOS) women and men (n = 1515) aged > or =30 y with BMI > or = 18.5 kg/m2 and without cardiovascular disease, diabetes, and cancer at baseline over a 16-y period. Diet quality was assessed using the validated Framingham Nutritional Risk Score. In women, older age (P Diet quality interacted with former smoking status (P-interaction = 0.02); former smokers with lower diet quality gained an additional 5.2 kg compared with those with higher diet quality (multivariable-adjusted P-trend = 0.06). Among men, older age (P smoking (P smoking status (P smoking status in men were stronger predictors of weight change than diet quality among FOS adults. Women who stopped smoking over follow-up and had poor diet quality gained the most weight. Preventive interventions need to be sex-specific and consider lifestyle factors.

This study had three goals. First, we examined the prevalence of the participant roles of bullying in middle adolescence and possible gender differences therein. Second, we examined the behavioral and status characteristics associated with the participant roles in middle adolescence. Third, we compared two sets of criteria for assigning students to the participant roles of bullying. Participants were 1,638 adolescents (50.9% boys, M(age) = 16.38 years, SD =.80) who completed the shortened participant role questionnaire and peer nominations for peer status and behavioral characteristics. Adolescents were assigned to the participant roles according to the relative criteria of Salmivalli, Lagerspetz, Björkqvist, Österman, and Kaukiainen (1996). Next, the students in each role were divided in two subgroups based on an additional absolute criterion: the Relative Only Criterion subgroup (nominated by less than 10% of their classmates) and the Absolute & Relative Criterion subgroup (nominated by at least 10% of their classmates). Adolescents who bullied or reinforced or assisted bullies were highly popular and disliked and scored high on peer-valued characteristics. Adolescents who were victimized held the weakest social position in the peer group. Adolescents who defended victims were liked and prosocial, but average in popularity and peer-valued characteristics. Outsiders held a socially weak position in the peer group, but were less disliked, less aggressive, and more prosocial than victims. The behavior and status profiles of adolescents in the participant roles were more extreme for the Absolute & Relative Criterion subgroup than for the Relative Only Criterion subgroup. © 2015 Wiley Periodicals, Inc.

Obesity is a biological risk factor or comorbidity that has not received much attention from scientists studying hypertension among African American men. The purpose of this study was to examine the relationship between weight status and high blood pressure among African American men with few economic resources. The authors used surveillance data collected from low-income adults attending community- and faith-based primary care clinics in West Tennessee to estimate pooled and group-specific regression models of high blood pressure. The results from group-specific logistic regression models indicate that the factors associated with hypertension varied considerably by weight status. This study provides a glimpse into the complex relationship between weight status and high blood pressure status among African American men. Additional research is needed to identify mechanisms through which excess weight affects the development and progression of high blood pressure. PMID:20937738

To investigate differences in physical activity and attitude toward physical activity in adolescents with different degrees of overweight and explore whether the prediction of physical activity by attitude is moderated by level of overweight. Subjects were divided into a normal-weight group (n = 37, 18.8 +/- 1.2 kg/m2), an overweight group (n = 28, 25.9 +/- 1.3 kg/m2), and an obese group (n = 24, 33.7 +/- 4.1 kg/m2). Mean age was 14.6 +/- 1.2 years, with 72% girls. Physical activity was estimated using the Baecke Questionnaire. Attitude was measured by assessing perceived benefits and barriers. Participation in sports was higher in normal-weight compared with overweight (p attitude compared with their normal-weight (p attitude was not moderated by level of overweight. This study demonstrates that overweight and obese adolescents show lower sport participation and have a less positive attitude toward physical activity. Interventions in youngsters with weight problems should try to increase participation in sports by making activities more fun and attractive for these youngsters.

We investigated the longitudinal associations between self-reported aggression, self-perceived social status, and dating in adolescence using an intrasexual competition theoretical framework. Participants consisted of 536 students in Grade 9 (age 15), recruited from a community sample, who were assessed on a yearly basis until they were in Grade 11 (age 17). Adolescents self-reported their use of direct and indirect aggression, social status, and number of dating partners. A cross-lagged panel model that controlled for within-time covariance and across-time stability while examining cross-lagged pathways was used to analyze the data. The findings revealed that direct aggression did not predict dating behavior and was negatively associated with self-perceived social status in Grade 10. Self-perceived social status in Grade 9 was positively associated with greater use of indirect aggression in Grade 10. Regarding dating, in Grade 9, self-perceived social status positively predicted more dating partners the following year, while in Grade 10, it was higher levels of indirect aggression that predicted greater dating activity the following year. Overall, there were no significant sex differences in the model. The study supports the utility of evolutionary psychological theory in explaining peer aggression, and suggests that although social status can increase dating opportunities, as adolescents mature, indirect aggression becomes the most successful and strategic means of competing intrasexually and gaining mating advantages. © 2018 Wiley Periodicals, Inc.
Full Text Available Adequate vitamin D and calcium are essential for optimal adolescent skeletal development. Adolescent vitamin D insufficiency/deficiency and poor calcium intake have been reported worldwide. Heavy alcohol use impacts negatively on skeletal health, which is concerning since heavy adolescent drinking is a rising public health problem. This study aimed to examine biochemical vitamin D status and dietary intakes of calcium and vitamin D in 12–16 year-old adolescents with alcohol use disorders (AUD, but without co-morbid substance use disorders, compared to adolescents without AUD. Substance use, serum 25-hydroxyvitamin D (s-25(OHD concentrations, energy, calcium and vitamin D intakes were assessed in heavy drinkers (meeting DSM-IV criteria for AUD (n = 81 and in light/non-drinkers without AUD (non-AUD (n = 81, matched for age, gender, language, socio-economic status and education. Lifetime alcohol dose was orders of magnitude higher in AUD adolescents compared to non-AUD adolescents. AUD adolescents had a binge drinking pattern and “weekends-only” style of alcohol consumption.

All participants were at risk of inadequate calcium and vitamin D intakes (Estimated Average Requirement cut-point method. Both groups were at risk of inadequate calcium intake and had poor biochemical vitamin D status, with binge drinking potentially increasing the risk of the latter. This may have negative implications for peak bone mass accrual and future osteoporosis risk, particularly with protracted binge drinking.
Full Text Available Recognising overweight and obesity is critical to prompting action, and consequently preventing and treating obesity. The present study examined the association between parental perceptions of child weight status and child's diet.Participants were members of the Gateshead Millennium Study. Parental perception of their child's weight status was assessed using a questionnaire and compared against International Obesity Task Force cut-offs for childhood overweight and obesity when the children were aged 6-8 years old. Diet was assessed at age 6-8years old using the FAST (Food Assessment in Schools Tool food diary method. The association between parental perception and dietary patterns as defined by Principal Components Analysis, was assessed using multivariate regression after adjustment for child's gender, child's weight status, maternal body mass index (BMI, maternal education and deprivation status.Of the 361 parents who provided complete data on confounders and on their perception of their child's weight status, 63 (17% parents perceived their child as being of 'normal' weight or 'overweight' when they were actually 'overweight' or 'obese', respectively. After adjustment for confounders, parents who misperceived their child's weight had children with a lower 'healthy' dietary pattern score compared to children whose parents correctly perceived their weight (β = -0.88; 95% CI: -1.7, -0.1; P-value = 0.028. This association was found despite higher consumption of reduced sugar carbonated drinks amongst children whose parents incorrectly perceived their weight status compared to children whose parents perceived their weight correctly (52.4% vs. 33.6%; P-value = 0.005.In conclusion, children whose parents did not correctly perceive their weight status scored lower on the 'healthy' dietary pattern. Further research is required to define parents' diets based on their perception status and to examine if a child's or parent's diet mediates the

To examine the effect of childhood trauma and family history of psychiatric illness on weight loss trajectories of obese, female adolescents with polycystic ovary syndrome (PCOS). Prospective study. PCOS and adolescent medicine outpatient clinics. Participants were, on average, 15.8 years of age, 80% Caucasian (39/49 participants), and had a body mass index of 36.8 ± 8.8. Healthy Bodies, Healthy Minds is an evidence-based one-on-one intervention consisting of 4 weekly sessions, 4 biweekly sessions, and 3 monthly booster sessions. Each session was 45-60 minutes long with 15-30 minutes of physical activity with a lifestyle coach. Paired sample t tests were used to assess group differences in pre- and post-treatment weight between participants reporting childhood trauma and body mass index-matched controls not endorsing trauma. One-way analysis of variance was performed to assess the influence of childhood trauma on weight loss between the 2 groups. Adolescents without a family history of psychiatric illness lost more weight (mean, -1.28 kg; SD, 6.89) than those who had a family history of psychiatric illness (mean, -0.64 kg; SD, 4.7) from baseline to booster session completion (6 months). However, results of independent t tests did not reveal statistically significant group differences in weight loss from baseline to booster session completion (t 21 = 0.51; P = .6). Obese adolescents with PCOS who have experienced childhood trauma can lose weight and acquire its health benefits when enrolled in an intervention addressing weight, mood, and sleep. Family history of psychiatric illness emerged as a potential predictor of lesser weight loss. Copyright © 2018. Published by Elsevier Inc.

We have a limited understanding of the objectively determined physical activity levels by weight control status (i.e., trying to lose weight, trying to maintain weight, and neither trying to lose or maintain weight) among U.S. adults with diabetes. Therefore, this study assessed the association between physical activity and weight control status among U.S. adults with diabetes. Cross-sectional survey. The 2003-2006 National Health and Nutrition Examination Survey (NHANES) was used, which is representative of the U.S. population. Subjects were 733 adults (≥20 years) with diabetes. Participants wore an accelerometer to assess physical activity, and questionnaires were used to assess weight control status and covariates. Multivariate negative binomial regressions were used. After adjustments, and compared to those not trying to lose or maintain their weight, women trying to lose weight engaged in 74% more physical activity (rate ratio = 1.74; 95% confidence interval [CI]: 1.14 to 2.65). Although findings were not significant for men, men were more likely than women to meet physical activity recommendations. Diabetic women trying to lose weight engaged in more physical activity than did their female counterparts not trying to lose or maintain their weight. Although men were more active than women, no differences in activity estimates occurred across weight control status for men.

Some markers of social disadvantage are associated robustly with depressive symptoms among adolescents: female gender and lower socioeconomic status (SES), respectively. Others are associated equivocally, notably Black v. White race/ethnicity. Few studies examine whether markers of social disadvantage by gender, SES, and race/ethnicity jointly predict self-reported depressive symptoms during adolescence; this was our goal. Secondary analyses were conducted on data from a socioeconomically diverse community-based cohort study of non-Hispanic Black and White adolescents (N = 1,263, 50.4% female). Multivariable general linear models tested if female gender, Black race/ethnicity, and lower SES (assessed by parent education and household income), and their interactions predicted greater depressive symptoms reported on the Center for Epidemiological Studies-Depression scale. Models adjusted for age and pubertal status. Univariate analyses revealed more depressive symptoms in females, Blacks, and participants with lower SES. Multivariable models showed females across both racial/ethnic groups reported greater depressive symptoms; Blacks demonstrated more depressive symptoms than did Whites but when SES was included this association disappeared. Exploratory analyses suggested Blacks gained less mental health benefit from increased SES. However there were no statistically significant interactions among gender, race/ethnicity, or SES. Taken together, we conclude that complex patterning among low social status domains within gender, race/ethnicity, and SES predicts depressive symptoms among adolescents.

Suicide is one of the most common causes of death among young people. A report from the US Surgeon General called for strategies to prevent suicide, including increasing public awareness of suicide and risks factors, and enhancing research to understand risk and protective factors. Weight perception has been linked to depression and poor self-esteem in adolescents. The purpose of this study was to examine the relationship between perceived weight status and suicidal thoughts and actions by gender in middle school youth. All public middle school students in 4 eastern North Carolina counties presented, and with parental permission (n = 5174), completed the Youth Risk Behavior Survey: Middle School Questionnaire. The 3 dependent variables were self-reported thinking, planning, and attempting suicide. Bivariate analyses describe suicidal thoughts and actions; multiple logistic regression models examined the relationship between weight description and suicidal thoughts and actions controlling for age, race, household composition, grades on report cards, and parents' education. Significantly more females than males reported thinking (26% vs 19%), planning (12% vs 9%), and attempting (11% vs 8%) suicide. For females, those who perceived themselves as overweight were significantly more likely to report suicidal thoughts and actions; while for males, perceptions of overweight and underweight were significantly associated with suicidal thoughts and actions. Controlling for personal and family characteristics, perceived weight status was significantly associated with suicidal thoughts and actions in middle school boys and girls.

Building self-esteem in overweight adolescents is key to long-term weight management; yet, self-esteem is rarely a key outcome of adolescent weight management interventions. This systematic review investigates the impact of multicomponent weight management interventions on self-esteem in overweight and obese adolescents. Six databases were searched in December 2014. Eligible studies met the following criteria: (1) randomized controlled trial, (2) overweight or obese participants, (3) adolescents (10-19 years), (4) multicomponent weight management intervention, (5) reported self-esteem and weight changes. Thirteen studies with 1,157 overweight or obese adolescents, aged 10-19 years, were included. Meta-analyses showed no significant change in self-esteem (0.27 [-0.04, 0.59]), but body mass index z -score reduced following intervention (-0.17 [-0.22, -0.11]). The lack of change in self-esteem suggests weight loss alone is insufficient to improve self-esteem. Multicomponent weight management interventions require a specific focus on self-esteem to improve this outcome in overweight and obese adolescents. © The Author 2017.

Underestimating one's weight is often seen as a barrier to weight loss. However, recent research has shown that weight underperception may be beneficial, with lower future weight gain and fewer depressive symptoms. Here, we examine the relationship between adolescent weight underperception and future blood pressure. Using data from the National Longitudinal Study of Adolescent to Adult Health, we obtained a nationally representative sample of 2,463 adolescents with overweight and obesity (students in grades 8-12 in 1996). We used multivariable linear regression to prospectively examine the relationship between weight self-perception in adolescence and blood pressure in adulthood (year 2008; follow-up rate 80.3%), controlling for age, gender, race/ethnicity, smoking, alcohol consumption, education level, household income, and body mass index. Additional analyses were stratified by gender and race/ethnicity. Youth with overweight/obesity who underperceived their weight had lower blood pressure in adulthood than those who perceived themselves to be overweight. The decrease in systolic blood pressure was -2.5 mm Hg (95% confidence interval: -4.3, -0.7; p = .006). Although the interaction by gender was statistically insignificant (p = .289), important differences appeared upon stratification by gender. Young men showed no significant difference in adult blood pressure related to weight self-perception. Conversely, in young women, weight underperception was associated with an average decrease in systolic blood pressure of -4.3 mm Hg (95% confidence interval: -7.0, -1.7; p = .002). Contrary to conventional wisdom, weight underperception is associated with improved health markers in young women. The observed differences in blood pressure are clinically relevant in magnitude, and interventions to correct weight underperception should be re-examined for unintended consequences.

Previous studies revealed that higher levels of acculturation are related to obesity in Hispanic adults. Conflicting findings exist regarding this relationship in children, and little is known about the impact of acculturation on children's success in pediatric weight management programs. The purposes of the study were to (1) examine the relationship between acculturation and overweight/obese weight status and (2) determine the impact of acculturation on the changes in weight status among overweight/obese children 12 and 24 months after having participated in a weight management intervention. This is a secondary analysis of aggregated data from three randomized control trials that occurred between 2005 and 2009. Height, weight, and level of acculturation using the Child Short Scale for Hispanics (C-SASH) were measured in a sample of Hispanic children (n = 559). Logistic regression models were used to study phase 1 (n = 559) and phase 2 (n = 142), controlling for child and family characteristics. Children reporting high levels of acculturation had a 52 % lower odds of being overweight or obese. Among overweight/obese children who participated in the intervention, high levels of acculturation demonstrated greater reductions in standardized body mass index (zBMI) at 24 months. The results of this study indicate a need to tailor weight management programs for Hispanic children who have lower levels of acculturation.
Full Text Available Abstract The increasing prevalence of overweight in young people suggests that adolescent nutritional status is influenced by environmental factors. Using hierarchical modelling, this study aimed to analyse the association between individual, household and neighborhood factors and adolescent nutritional status and well-being. The study used data from a population-based household survey conducted in Belo Horizonte, the capital of the State of Minas Gerais, Brazil, between 2008 and 2009. Data was obtained from an adult and adolescent in each household using a confidential questionnaire and anthropometric measurements. Adolescent nutritional status was evaluated using multinomial regression analysis considering distal and proximal influences. The prevalence of overweight and thinness among the sample of 1,030 adolescents was 21.9% and 4.6%, respectively. Although variables from all blocks remained in the final model, head of household education level, family habits and family nutritional status were shown to strongly influence adolescent nutritional status. New approaches to public health are needed which focus on raising awareness and promoting health education targeting teenagers and their social context.

Maternal nutritional status of pre pregnancy and gestational weight gain affects the preterm birth. The association between maternal nutritional status of pre pregnancy and preterm birth appears to be complex and varied by studies from different countries, thus this association between the gestational weight gain and preterm birth is more consolidated. The study aims to determine any association between the pre pregnancy maternal nutritional status, gestational weight gain and the preterm birth rate in the Albanian context. In case control study, we analyzed women who have delivered in obstetric institutions in Tirana during the year 2012. Body mass index and gestational weight gain of 150 women who had a preterm delivery were compared with those of 150 matched control women who had a normal delivery regarding the gestation age. The self-reported pre pregnancy weight, height, gestational weight gain, age, education and parity are collected through a structured questioner. The body mass index and gestational weight gain are categorized based on the Institute of Medicine recommendation. The multiple logistic regression is used to measure the association between the nutritional status of pre pregnancy and gestational weight gain and the preterm birth rate. The women which have a underweight status or obese of pre pregnancy are more likely to have a preterm birth compared to the women of a normal pre-pregnancy nutritional status (respectively OR =2.7 and 4.3 pnutritional status and gestational weight gain affects the risk for preterm birth. Pre-pregnancy and gestation nutritional assessments should be part of routine prenatal visits.

The first objective of this study was to evaluate the nutritional status and insulin resistance index in a population of adolescents as calculated by Homeostatic Model Assessment (HOMA). The second objective was to establish correlations between the nutritional status of the subjects, the possible existence of insulin resistance, and the risk of high blood pressure. POPULATION SAMPLE AND METHODOLOGY: The sample was composed of 1001 adolescents, 9-17 years of age, from 18 schools in the provinces of Granada and Almeria. Their nutritional status was determined by means of anthropometric evaluation. For the metabolic study, a blood sample was collected from each subject by venipuncture. An analysis was performed of the basal glucose and insulin levels as well as the Homeostatic Model Assessment- Insulin Resistance (HOMAIR) index. Also evaluated were the levels of glycosylated haemoglobin (HbA1c), serum lipoprotein (a), and non-esterified fatty acids (NEFAs). Insulin resistance was calculated with the formula, proposed by Matthews et al. (1985) : HOMA-IR = (insulin[mmol/L] x glucose[mU/L])/22.5. The evaluation of the nutritional status of the subjects reflected a progressive increase in the values of anthropometric variables as the nutritional status of the subjects worsened. The results of this study showed, regardless of age and gender, 85.01% of the subjects were of normal weight, whereas 9.99% were overweight, and 4.99% were obese. The metabolic study reflected that in comparison to normal-weight and overweight students, obese students had significantly higher serum levels (p < 0,0001) of HbA1c, basal insulin, basal glycemia, basal NEFA, lipoprotein (a), and HOMA-IR. Obesity was found to be a serious health problem in the population of adolescents studied, especially given the high cardiovascular risk that is characteristic of this condition. As reflected in the results of this study, obesity led to the premature development of metabolic disorders, which generally

Childhood obesity, a growing epidemic, is associated with greater risk of several chronic diseases in adulthood. Children of immigrant mothers are at higher risk for obesity than children of non-immigrant mothers. High birth weight is the most important neonatal predictor of childhood obesity in the general population. To understand the etiology of obesity in children of immigrant mothers, we assessed the relation between maternal immigrant status and risk for high birth weight. Data about all births in Michigan (N = 786,868) between 2000-2005 were collected. We used bivariate chi-square tests and multivariate logistic regression models to assess the relation between maternal immigrant status and risk for neonatal high birth weight. The prevalence of high birth weight among non-immigrant mothers was 10.6%; the prevalence among immigrant mothers was 8.0% (P maternal age, education, marital status, parity, and tobacco use, children of immigrant mothers had lower odds (odds ratio = 0.69, 95% confidence interval = 0.67-0.70) of high birth weight compared to those of non-immigrant mothers. Although maternal immigrant status has been shown to be associated with greater childhood obesity, surprisingly, children of immigrant mothers have lower risk of high birth weight than children of non-immigrant mothers. This suggests that factors in early childhood, potentially cultural or behavioral factors, may play a disproportionately important role in the etiology of childhood obesity in children of immigrant vs non-immigrant mothers.

Examine whether unhealthy and extreme weight control behaviors (WCBs) mediate the relationship between youth weight status and disease-specific health-related quality of life (HRQOL) in treatment-seeking youth who are overweight and obese (OV/OB). 82 youth 10-17 years of age who were OV/OB and attending an outpatient obesity-related medical appointment completed measures assessing unhealthy and extreme WCBs and disease-specific HRQOL. Parents completed a demographic questionnaire and medical staff measured youth height and weight. Regression analyses revealed that unhealthy WCBs mediated the associations between youth weight status and emotional and social avoidance disease-specific HRQOL, such that higher body mass index (BMI) predicted unhealthy WCBs, which were ultimately associated with poorer emotional and social HRQOL. Mediation analyses were not significant for total, physical, teasing/marginalization, and positive attributes disease-specific HRQOL. In addition, extreme WCBs did not mediate the association between youth weight status and any subscales of the disease-specific HRQOL measure. Weight status is an important predictor of disease-specific HRQOL in OV/OB youth; however, the association with emotional and social HRQOL is partially accounted for by youth engagement in unhealthy WCBs. Clinicians and researchers should assess WCBs and further research should explore and evaluate appropriate intervention strategies to address unhealthy WCBs in pediatric weight management prevention and treatment efforts.
Full Text Available Background. Longitudinal investigations into the origins of adult essential hypertension have found elevated blood pressure in children to accurately track into adulthood, however the direct causes of essential hypertension in adolescence and adulthood remains unclear.Methods. We revisited 152 Peruvian adolescents from a birth cohort tracked from 0 to 30 months of age, and evaluated growth via monthly anthropometric measurements between 1995 and 1998, and obtained anthropometric and blood pressure measurements 11–14 years later. We used multivariable regression models to study the effects of infantile and childhood growth trends on blood pressure and central obesity in early adolescence.Results. In regression models adjusted for interim changes in weight and height, each 0.1 SD increase in weight for length from 0 to 5 months of age, and 1 SD increase from 6 to 30 months of age, was associated with decreased adolescent systolic blood pressure by 1.3 mm Hg (95% CI −2.4 to −0.1 and 2.5 mm Hg (95% CI −4.9 to 0.0, and decreased waist circumference by 0.6 (95% CI −1.1 to 0.0 and 1.2 cm (95% CI −2.3 to −0.1, respectively. Growth in infancy and early childhood was not significantly associated with adolescent waist-to-hip ratio.Conclusions. Rapid compensatory growth in early life has been posited to increase the risk of long-term cardiovascular morbidities such that nutritional interventions may do more harm than good. However, we found increased weight growth during infancy and early childhood to be associated with decreased systolic blood pressure and central adiposity in adolescence.

Because of high rates of pregnancy and sexually transmitted infections among adolescents, factors influencing adolescents' contraceptive use require close examination. This study explores how different types of partner communication relate to contraceptive use among adolescent girls and whether these associations vary by relationship status. Cross-sectional, self-report data from 253 sexually active 13- to 17-year-old girls were used to examine associations between partner communication, relationship status, and contraceptive consistency. In a multivariate analysis, partner communication specific to contraceptive use (RR = 1.3, p communication on hormonal consistency was greater in steady partnerships than in casual partnerships. Findings suggest that clinicians should ask about the nature of adolescent girls' relationships with their sexual partners when encouraging contraceptive use. Early communication with partners about sexual topics should be stressed, especially among girls in steady relationships. Copyright © 2015 National Association of Pediatric Nurse Practitioners.

We investigated the association between birth parameters (weight, length, and head circumference) and time spent in physical activity (outdoor and indoor) and screen time (TV viewing, computer, and videogame usage) among adolescents. A longitudinal cohort study surveyed 1794 children in 2004-2005 (median age = 12.7 yr), and 752 were resurveyed 5 yr later in 2009-2010 (age = 17-18 yr). Adolescents completed detailed activity questionnaires. Parents extracted birth parameter data from their child's health record booklet. After adjusting for age, sex, ethnicity, gestational age, parental education, home ownership, exposure to passive smoking, and body mass index, 12-yr-old children in the highest compared with the lowest quartile of birth weight spent on average approximately 56 and 62 min more in total (Ptrend = 0.02) and outdoor physical activity (Ptrend = 0.02) per week, respectively. Similarly, 12-yr-old children in the high (>4000 g) versus very low (adolescence. Hence, this could be part of the underlying mechanism between prenatal influences and future disease risk and could have possible clinical implications.

We examined perpetration of bullying among youths in vulnerable groups relative to youths in peer groups not categorized as vulnerable. Data were collected in 2013 from a large school-based survey of adolescents conducted in Minnesota (n = 122,180). We used the χ(2) test and logistic regression to compare measures of perpetration of physical and relational bullying, as well as experiences of victimization and perpetration (or both), across categories of sexual orientation, weight status, and disability status. Rates of physical and relational bullying perpetration were significantly higher among youths in vulnerable groups than among those not in vulnerable groups. With respect to context of victimization experiences, young men and women from vulnerable groups were overrepresented in the group comprising both perpetrators and victims. For example, odds of being both a perpetrator and a victim were 1.41 to 3.22 times higher among gay, lesbian, and bisexual youths than among heterosexual youths. Vulnerable youths, who are prone to peer harassment, may also act as perpetrators of bullying. Prevention strategies should address the particular needs of these populations; targeted programming may be appropriate.

To analyze the relationship between self-concept, aerobic capacity and weight status in schoolchildren. Relational descriptive design in which was assessed the weight status and aerobic capacity of 256 schoolchildren among 8-11 years. Aerobic capacity (low vs high) and the body mass index (normal-weight vs overweight-obesity) were categorized using standard criteria. The self-concept was assessed through the Piers Harris self-concept scale for children. Schoolchildren with normal-weight and high fitness level showed better levels of conductual self-concept (P=.030), physical (Pself-concept (P=.002). The schoolchildren with normal-weight show higher levels of conductual self-concpt (P=.016), intellectual (P=.050), physical (Pself-concept (P=.001). The schoolchildren with a higher fitness level showed better conductual self-concept (P=.024), physical (P=.004), lack of anxiety (P=.011), social (P=.024), and global (P=.003). The results of the study strengthen the importance to transmit to the educative community the knowledge of the relationship between the variables analyzed aiming to improve the schoolchildren self-concept.

Full Text Available In this paper, we investigated the sexual activity levels of several subtypes of middle adolescents (age 14–15 years. The subtype profiles were based on dominance-popularity status and a range of behaviors associated with dominance and popularity. In addition, gender differences in behavioral profiles were examined among dominant-popular, sexually active young adolescents. Results showed that socially dominant and popular young adolescent boys who exhibited a highly aggressive profile were more sexually active than their low-status and non-aggressive male peers; dominant-popular girls who were very attractive and gossips were more sexually active than their female peers. The results are discussed from an evolutionary psychological framework.

Nearly 70% of adult Americans are overweight or obese, but the associations between physical activity, diet quality, and weight status have not been examined in a representative sample of US adults. The purpose of this study was to examine the associations among moderate-to-vigorous physical activity (MVPA), diet quality, and weight status within and across age groups in US adults. Participants included 2587 men and 2412 women age 20 to ≥70 yr from the National Health and Nutrition Examination Survey 2003-2004 and 2005-2006. Physical activity was measured by accelerometry. Diet quality was assessed with overall Healthy Eating Index-2005 scores. Measures of weight status, body mass index (BMI), and waist circumference were assessed using standard National Health and Nutrition Examination Survey protocols. Across age groups, MVPA was lower in the older age groups for both men and women, whereas diet quality was higher (P men and women in nearly every age group (P men age 30-39, 40-49 (BMI only), and 50-59 yr and women age 50-59 yr (P physical activity, and diet quality in US men and women. MVPA was very consistently related to weight status in both genders. The relation between diet quality and weight status was less consistent. These findings provide support for public health efforts to prevent obesity by promoting increased physical activity in adult Americans.

METHODS: The sample consisted of 10 families selected among participants in a 1-year multidisciplinary family-based weight...
Full Text Available Background: In this study, we aim to compare insulin and leptin levels in adolescents with or without excess weight and in those with or without abdominal obesity. Materials and Methods : This case-control study was conducted among 486 samples. We randomly selected 243 overweight and an equal number of normal-weight adolescents from among participants of the third survey of a national surveillance program entitled "Childhood and Adolescence Surveillance and PreventIon of Adult Non-communicable diseases study." Serum insulin and leptin were compared between two groups and their correlation was determined with other variables. Results: The mean age and body mass index (BMI of participants were 14.10 ± 2.82 years and 22.12 ± 6.49 kg/m 2 , respectively. Leptin and insulin levels were higher in overweight than in normal-weight adolescents (P < 0.05. Leptin level was higher in children with abdominal obesity than in their other counterparts (P < 0.001. Leptin level was correlated with age, fasting blood glucose, BMI, and insulin level. Conclusion: Insulin and leptin levels were higher among overweight and obese children, which may reflect insulin and leptin-resistance. Given the complications of excess weight from early life, prevention and controlling childhood obesity should be considered as a health priority.

Nutritional status among adolescents is an important health indicator. The up-to-date information about nutritional status and food consumption pattern in the remote rural area is required for the effective public health intervention in the rural area of the country. The present study aimed to demonstrate the prevalence of malnutrition, eating behavior and nutritional knowledge among secondary school students in a remote rural area in Thailand. Body weight and height data were collected from 298 secondary school students for nutritional status calculation using the Institute of Nutrition Research, Mahidol University, INMU-Thaigrowth program. Eating behavior and nutritional knowledge were observed by self-administrated questionnaires. The prevalence low height-for-age (instant noodles (64.4%). The prevalence of malnutrition was low among this population. The studied population had a fair knowledge about nutrition. The authoes found that regular consumption of highly commercialized snack products especially salted chips and instant noodles were at a high level in this remote rural area of Thailand. The pattern of nutritional problems in Thailand may have changed in which a public health program for children in rural areas of the country should recognize this transition.

The purpose of this project was to quantitatively test differences in subjective social status scores between non-pregnant and pregnant women to determine the role of subjective social status in birth weight variation between Mexico-born and US-born Mexican-American women. Six hundred low-income pregnant and non-pregnant Mexican immigrant and Mexican-American women in south Texas were surveyed for subjective social status, depression, perceived social stress, parity, and pregnancy intendedness. Psychosocial health variables, parity, and pregnancy intendedness were included due to their significant associations with low birth weight. Pregnant women had higher subjective social status scores than non-pregnant women. The difference in scores between non-pregnant and pregnant women was smaller in Mexican immigrant women than Mexican-American women. Pregnancy intendedness did not influence subjective social status in pregnant women of either sample, but having children (parity) in both samples was associated with higher subjective social status scores. Among Mexican-American women, community subjective social status was correlated with levels of depressive symptoms and perceived social stress. Subjective social status, depression, and perceived social stress were not correlated among Mexican immigrant women. Our results suggest that incorporation into the USA influences maternal mental health vis-à-vis changes in how women of reproductive age think about themselves and their gender roles in relation to others. Theoretically, our work supports mixed-method approaches to document how culture change as a result of immigration may impact maternal and infant health. Future research should test whether the effect of subjective social status on birth weight occurs when subjective social status does not correlate with depression or stress.

Obese adolescents suffer negative social experiences, but no studies have examined whether obesity is associated with dysfunction of the social brain or whether social brain abnormalities relate to disadvantageous traits and social decisions. We aimed at mapping functional activation differences in the brain circuitry of social decision making in adolescents with excess versus normal weight, and at examining whether these separate patterns correlate with reward/punishment sensitivity, disordered eating features, and behavioral decisions. In this fMRI study, 80 adolescents aged 12 to 18 years old were classified in two groups based on age adjusted body mass index (BMI) percentiles: normal weight (n = 44, BMI percentiles 5th-84th) and excess weight (n = 36, BMI percentile ≥ 85th). Participants were scanned while performing a social decision-making task (ultimatum game) in which they chose to "accept" or "reject" offers to split monetary stakes made by another peer. Offers varied in fairness (Fair vs. Unfair) but in all cases "accepting" meant both players win the money, whereas "rejecting" meant both lose it. We showed that adolescents with excess weight compared to controls display significantly decreased activation of anterior insula, anterior cingulate, and midbrain during decisions about Unfair versus Fair offers. Moreover, excess weight subjects show lower sensitivity to reward and more maturity fears, which correlate with insula activation. Indeed, blunted insula activation accounted for the relationship between maturity fears and acceptance of unfair offers. Excess weight adolescents have diminished activation of brain regions essential for affective tracking of social decision making, which accounts for the association between maturity fears and social decisions. © 2014 Wiley Periodicals, Inc.

Peer cliques form an important context for the social development of adolescents. Although clique members are often similar in social status, also within cliques, status differences exist. How differences in social status between clique members are related to behaviors of its individual members is rather unknown. This study examined to what extent the relationship of individual social status (i.e., perceived popularity) with aggression and prosocial behavior depends on the level of internal clique hierarchy. The sample consists of 2674 adolescents (49.8% boys), with a mean age of 14.02. We focused specifically on physical and relational aggression, and practical and emotional support, because these behaviors have shown to be of great importance for social relationships and social standing among adolescents. The internal status hierarchy of cliques was based on the variation in individual social status between clique members (i.e., clique hierarchization) and the structure of status scores within a clique (pyramid shape, inverted pyramid, or equal distribution of social status scores) (i.e., clique status structure). The results showed that differences in aggressive and prosocial behaviors were particularly moderated by clique status structure: aggression was stronger related to individual social status in (girls') cliques where the clique status structure reflected an inverted pyramid with relatively more high status adolescents within the clique than low status peers, and prosocial behavior showed a significant relationship with individual social status, again predominantly in inverted pyramid structured (boys' and girls') cliques. Furthermore, these effects differed by types of gender cliques: the associations were found in same gender but not mixed-gender cliques. The findings stress the importance of taking into account internal clique characteristics when studying adolescent social status in relationship to aggression and prosociality.

The metabolic syndrome (MetS) in adolescents is a growing problem. The objectives were to verify the association among early predictors such as birth weight, breastfeeding, maternal weight status, smoking during pregnancy, and the development of MetS. A cross-sectional study was performed of 976 children and adolescents, 10-15 years of age, at schools in the provinces of Granada and Almeria (Spain). For this purpose, we analyzed the physical characteristics as well as the biochemical markers of the participants with a view to ascertaining the prevalence of the MetS. Relevant data were also extracted from the clinical histories of their mothers. It was found that 3.85% of the female subjects and 5.38% of the male subjects in the sample population suffered from MetS. In both sexes, there was an association between birth weight and positive MetS diagnosis (OR 1.27). For both males and females, there was an inverse association between the length of time that they had been breastfed and positive MetS diagnosis (OR1-3 months 3.16; OR4-6 months 1.70; OR(>6 months) 0.13). There was also a significant association between maternal weight (OR(overweight )30.79; OR(obesity) 49.36) and cigarette consumption during pregnancy (OR 1.47) and the subsequent development of MetS in the children of these mothers. Those subjects born with a higher than average birth weight had a greater risk of developing MetS in childhood and adolescence. Breastfeeding children for longer than 6 months protected them from MetS in their early years as well as in their teens. Other risk factors for MetS were maternal smoking during pregnancy as well as maternal overweight and obesity.
Underweight incidence in adolescents from less urbanized regions of Poland depended on socio-economic status. An adolescent with average socio-economic status was 3 times less likely to be underweight than an adolescent with low socio-economic status. The correlation between socio-economic status and overweight and obesity was not significant.

Purpose Current refeeding recommendations for adolescents hospitalized with anorexia nervosa (AN) are conservative, starting with low calories and advancing slowly to avoid refeeding syndrome. The purpose of this study was to examine weight change and clinical outcomes in hospitalized adolescents with AN on a recommended refeeding protocol. Methods Adolescents aged 13.1–20.5 years were followed during hospitalization for AN. Weight, vital signs, electrolytes, and 24-hour fluid balance were measured daily. Percent median body mass index (%MBMI) was calculated as 50th percentile BMI for age and gender. Calories were prescribed on admission and were increased every other day. Results Thirty-five subjects with a mean (SD) age of 16.2 (1.9) years participated over 16.7 (6.4) days. Calories increased from 1,205 (289) to 2,668 (387). No subjects had refeeding syndrome; 20% had low serum phosphorus. Percent MBMI increased from 80.1 (11.5) to 84.5 (9.6); overall gain was 2.10 (1.98) kg. However, 83% of subjects initially lost weight. Mean %MBMI did not increase significantly until day 8. Higher calories prescribed at baseline were significantly associated with faster weight gain (p = .003) and shorter hospital stay (p = .030) in multivariate regression models adjusted for %MBMI and lowest heart rate on admission. Conclusions Hospitalized adolescents with AN demonstrated initial weight loss and slow weight gain on a recommended refeeding protocol. Higher calorie diets instituted at admission predicted faster weight gain and shorter hospital stay. These findings support the development of more aggressive feeding strategies in adolescents hospitalized with AN. Further research is needed to identify caloric and supplementation regimens to maximize weight gain safely while avoiding refeeding syndrome. PMID:22188830
To examine whether certain biological, sociocultural, and psychological factors differentiate dieters from nondieters in male and female, black and white adolescents. In each race-sex group adolescents were divided into nondieters and dieters (those who had lost at least 5 lb through dieting) and compared using factors associated with overweight and dieting. Participants were 1,269 high school seniors, with a mean (+/- standard deviation) age of 17.5 +/- 0.6 years, from 10 schools in a large metropolitan area (72% of enrolled students). Each student completed a self-administered questionnaire designed for this research, the Culture-Free Self-Esteem Inventory, and the Eating Disorder Inventory. Comparisons were made of dieters and nondieters using their previous and current weights, parental weights, birth order, socioeconomic status, religious affiliation, self-esteem scores, and other psychological factors. Statistical analyses performed were chi 2 and t tests. Factors thought to be associated with overweight in adolescents, such as parental weights, birth order, and socioeconomic status, were not found to be significantly different in dieters and nondieters in any of the four race-sex groups. In fact, the majority of dieters in this study were not overweight (ie, above the 85th percentile of body mass index). Instead, what most clearly distinguished dieters from nondieters was their perception of being overweight before kindergarten, after kindergarten, and at the time of the study, and the feelings of body dissatisfaction and wanting to be thinner that being overweight engenders. Because most adolescents diet because they perceive themselves to be overweight when they are not, adolescent dieters are not easy to identify. Instead, dietitians can offer educational programs that help all adolescents accept more realistic weights and adopt patterns of eating and exercise that remove or reduce the need to diet.

Summary It is commonly assumed that a person identifying that they are ‘overweight’ is an important prerequisite to successful weight management. However, there has been no systematic evaluation of evidence supporting this proposition. The aim of the present research was to systematically review evidence on the relationship between perceived overweight and (i) weight loss attempts, (ii) weight control strategies (healthy and unhealthy), (iii) weight‐related behaviours (physical activity and eating habits), (iv) disordered eating and (v) weight change. We synthesized evidence from 78 eligible studies and evaluated evidence linking perceived overweight with outcome variables separately according to the gender, age and objective weight status of study participants. Results indicated that perceived overweight was associated with an increased likelihood of attempting weight loss and with healthy and unhealthy weight control strategies in some participant groups. However, perceived overweight was not reliably associated with physical activity or healthy eating and was associated with greater disordered eating in some groups. Rather than being associated with improved weight management, there was consistent evidence that perceived overweight was predictive of increased weight gain over time. Individuals who perceive their weight status as overweight are more likely to report attempting weight loss but over time gain more weight. PMID:29266851

To examine the impact of daily exposure to a low-energy-dense (LED) or a high-energy-dense (HED) snack food on its reinforcing value (RRV) in adolescents with healthy weight, overweight, or obesity. A parallel-group, randomized trial was used to assess RRV of LED or HED snack food at baseline and again after exposure to that snack food daily for 2 weeks in 77 adolescents, aged 13 to 17 years. Information on eating-related subject characteristics was also collected at baseline. After 2 weeks of daily exposure, the RRV of the snack foods was significantly reduced in all participants, regardless of energy density or participant weight status. Among individuals who were high in dietary restraint only, those randomized to LED food found their snack food less reinforcing at baseline than those who were randomized to HED food. Baseline eating-related variables also differed as a function of weight status. Daily exposure to snack food in adolescents reduces the RRV of that food regardless of snack food energy density or weight status of the adolescent. This finding differs from adults, suggesting that increases in RRV of HED food after repeated exposure may develop after adolescence. © 2017 The Obesity Society.

This study used self-determination theory (Deci, E.L., & Ryan, R.M. (2000). The 'what' and 'why' of goal pursuits: Human needs and the self-determination of behavior. Psychological Inquiry, 11, 227-268.) to examine predictors of body image concerns and unhealthy weight control behaviours in a sample of 350 Greek adolescent girls. A process model was tested which proposed that perceptions of parental autonomy support and two life goals (health and image) would predict adolescents' degree of satisfaction of their basic psychological needs. In turn, psychological need satisfaction was hypothesised to negatively predict body image concerns (i.e. drive for thinness and body dissatisfaction) and, indirectly, unhealthy weight control behaviours. The predictions of the model were largely supported indicating that parental autonomy support and adaptive life goals can indirectly impact upon the extent to which female adolescents engage in unhealthy weight control behaviours via facilitating the latter's psychological need satisfaction.

Contingency management (CM) interventions, which use operant conditioning principles to encourage completion of target behavioral goals, may be useful for improving adherence to behavioral skills training (BST). Research-to-date has yet to explore CM for weight loss in minority adolescents. To examine the effects of CM in improving adolescent weight loss when added to BST. The study utilized an innovative experimental design that builds upon multiple baseline approaches as recommended by the National Institutes of Health. Six obese African-American youth and their primary caregivers living in Detroit, Michigan, USA. Adolescents received between 4 and 12 weeks of BST during a baseline period and subsequently received CM targeting weight loss. Youth weight. Linear mixed effects modeling was used in the analysis. CM did not directly affect adolescent weight loss above that of BST (p=0.053). However, when caregivers were involved in CM session treatment, contingency management had a positive effect on adolescent weight loss. The estimated weight loss due to CM when caregivers also attended was 0.66 kg/week (pcontingency management for minority youth weight loss. Lessons learned from contingency management program implementation are also discussed in order to inform practice.

Milk intake of breast-fed infants and body composition of 47 lactating mothers from Northwest and Central Mexico were monitored at 1 and 3 mo postpartum by the deuterium dilution technique and infrared detection. Milk quality was evaluated directly as milk composition and indirectly by infant growth. Maternal body fat tended to be lower in Central than in Northwest Mexico and was significant at 1 mo postpartum (p<0.001). BMI correlated positively with percentage body fat at 1 mo (r = 0.79, p<0.0001) and 3 mo (r = 0.76, p<0.0001). In Central Mexico, mean maternal energy intake was 19.4 and 23% below the RDA at 1 and 3 mo postpartum respectively. There were no differences in TBW, percentage body fat, BMI energy intake and estimated energy expenditure by activity diary between adolescent and adult women. Milk production rates averaged 573 vs 865 g/d at 1 and 3 mo postpartum in Northwest Mexico and 680 vs 857 g/d in Central Mexico and were not different between areas. Infants' energy intakes in Northwest Mexico at 1 and 3 mo postpartum were not significantly different. Fat intake at 3 mo was significantly lower in Central than in Northwest Mexico (p<0.05). Weight for age and weight for length Z scores were above +0.5 for infants from Northwest region, while for those in Central Area was between 0 and + 0. 5 at 2 and 3 mo. There were no differences (p>0.05) in Z score values for weight/length for infants in the two regions at 3 mo. Neither adolescent or adult mothers from Northwest or Central Mexican regions were undernourished and they produced adequate milk volume and composition to feed their infants and maintain their growth pattern until 3 months postpartum.

Full Text Available Besides other explanatory variables, parenting styles and parental violence might also be responsible for setting a path towards overweight/obesity in childhood. While this association has consistently been observed for adults, findings for adolescents still remain scarce and inconsistent. Therefore, the goal of this study is to add evidence on this topic for children and adolescents. Analyses are based on a sample of 1729 German, ninth-grade students. To analyze associations between parenting dimensions and weight status, non-parametric conditional inference trees were applied. Three gender-specific pathways for a heightened risk of overweight/obesity were observed: (1 female adolescents who report having experienced severe parental physical abuse and medium/high parental warmth in childhood; (2 male adolescents who report having experienced low or medium parental monitoring in childhood; and (3 this second pathway for male adolescents is more pronounced if the families receive welfare. The importance of promoting parenting styles characterized by warmth and a lack of physical abuse is also discussed. This is one of only a few studies examining the association of parenting dimensions/parental physical abuse and weight status in adolescence. Future studies should include even more parenting dimensions, as well as parental physical abuse levels, in order to detect and untangle gender-specific effects on weight status.

Overweight and the metabolic syndrome have become major problems, especially in children and adolescents. Obesity at a young age increases the risk for cardiovascular diseases and diabetes mellitus later in life. An early event in the development of cardiovascular disease is endothelial dysfunction which is found in obese young individuals. Increased activity of the enzyme arginase has been described as a central mechanism for endothelial dysfunction, especially in patients with diabetes mellitus. The aim of the study was to determine plasma levels of arginase in overweight adolescents. Sixty-six male German adolescents (age: 15.2 ± 1.1 years old) were included. Thirty-one of them were overweight (>90th age-specific weight percentile). Plasma arginase I and tumor necrosis factor alpha (TNFα) were determined. In addition, clinical data were recorded and anthropometrical measurements of obesity were performed. Overweight adolescents had a higher systolic blood pressure, lower high-density lipoprotein and increased levels of high-sensitive C-reactive protein (CRP). Circulating arginase I was elevated in overweight adolescents (95.8 ± 68.2 ng/ml) compared to normal weight adolescents (39.3 ± 26.9 ng/ml, p obesity. There was no difference between the two groups regarding TNFα. We demonstrate that arginase I levels are increased in obese adolescents. Knowing the important role for arginase in endothelial dysfunction, elevated levels of arginase I may represent a link between obesity, endothelial dysfunction and related comorbidities. © 2013 John Wiley & Sons A/S.

Childhood overweight and obesity is a major public health challenge for policymakers in many countries. As the most common supervisors of children's activities, parents have a potentially important role to play in obesity prevention. However, a precondition for parents to improve their children's diets, encourage them to be more physically active, or take them to see a doctor about their weight is for the parent to first recognize that their child is overweight or obese. This paper examines the extent of parental misclassification of child weight status, and its correlates, focusing on the role of parental education and the parent's own obesity status. We find evidence that, among non-obese parents, those who are better-educated report their child's weight status more accurately, but among obese parents, the better-educated are 45.18% more likely than parents with lower secondary education to give a false negative report of their child's overweight/obesity; this may reflect social desirability bias.

The association of secondary amenorrhea with extreme forms of substance use, weight control, and exercise in nonrepresentative samples raises questions as to whether adolescents in the general population who engage in these behaviors are at increased risk for secondary amenorrhea. We examined the prevalence and behavioral correlates of secondary amenorrhea in a county-wide high school population of 2544 girls aged 13 to 18. A survey questionnaire, which elicited menstrual history as well as weight history, weight control practices, level of exercise, and use of cigarettes, wine, and beer, was administered during school hours; absentees were also surveyed. The completion rate was 91%. The 1-year prevalence of secondary amenorrhea was 8.5%. Secondary amenorrhea was associated with smoking one or more packs of cigarettes per day (adjusted relative risk [RRa] = 1.96, 1.21-3.10), with multiple binge-eating behaviors in combination with laxative use or self-induced vomiting (RRa = 4.17, 2.54-6.32), and with weight fluctuation due to weight control (RRa = 2.59, 1.33-4.79). There was no association between amenorrhea and alcohol consumption or exercise level. Estimates of attributable risk are provided and indicate that bulimic behaviors and cigarette smoking may result in a considerable excess of cases of secondary amenorrhea in an adolescent population.

Full Text Available Objective: To evaluate eating disorders risk behaviors and unhealthy weight control practices among adolescents who consider themselves as vegetarians and those who are omnivorous.Material and Methods: A cross-sectional study was conducted in 12 technical schools in the city of São Paulo, Brazil. The sample included 1167 adolescents (51% female, aged 14 to 19 (mean age, 16. Adolescents stated whether they were currently vegetarian, and the sample was dichotomized as vegetarian and non-vegetarian. The two groups were compared as regards weight status, eating disorder risk behavior, unhealthy weight control methods and the perception of healthy eating.Results: About 4% of the sample was currently vegetarian, most of them female (70.8%, and females were 2.89 times more likely to be vegetarian than males. No relationship was found between the vegetarian status and unhealthy weight control behavior; however the vegetarian group considered their diet to be healthier than the non-vegetarian group (P=.04.Conclusions: The frequency of vegetarianism, as well the frequency of eating disorder risk behaviors had no association in this adolescent sample from São Paulo, Brazil.

To analyze the association of weight status with anxiety, depression, quality of life and physical fitness in fibromyalgia (FM) patients. The sample comprised 175 Spanish female FM patients (51.2 ± 7 years). We assessed quality of life by means of the Short-Form-36 Health Survey (SF36) and anxiety and depression by means of the Hospital Anxiety and Depression Scale (HADS). We used standardized fieldbased fitness tests to assess cardiorespiratory fitness, muscular strength, flexibility, agility, and static and dynamic balance. BMI was calculated and categorized using the international criteria. 33% of the sample was normal-weight, 35% overweight and 33% obese. HADS-anxiety and HADS-depression levels increased across the weight status categories. Obese patients had higher anxiety and depression levels compared to normal-weight patients (p < 0.05) whereas no differences were observed between overweight and obese patients. Physical functioning, bodily pain, general health (all p < 0.01) and mental health (p < 0.05) subscales from the SF36 were worse across the weight status categories. Likewise, levels of cardiorespiratory fitness, dynamic balance/motor agility (both p < 0.05) and upper-body flexibility (p < 0.001) decreased as the weight status increased. Pairwise comparisons showed significant differences mainly between the normal-weight versus obese groups. Obese female FM patients displayed higher levels of anxiety and depression and worse quality of life, cardiorespiratory fitness, dynamic balance/motor agility and upper-body flexibility than their normal-weight peers.

Full Text Available Being overweight or obese is one of the most common reasons that children and adolescents are teased at school. We carried out a study in order to investigate: i the relation between weight status and school bullying and ii the relation between weight status categories and types of victimization and bullying in an outpatient sample of Italian children and adolescents with different degrees of overweight from minimal overweight up to severe obesity.Nine-hundred-forty-seven outpatient children and adolescents (age range 6.0-14.0 years were recruited in 14 hospitals distributed over the country of Italy. The participants were classified as normal-weight (N = 129, overweight (N = 126, moderately obese (N = 568, and severely obese (N = 124. The nature and extent of verbal, physical and relational bullying and victimization were assessed with an adapted version of the revised Olweus bully-victim questionnaire. Each participant was coded as bully, victim, bully-victim, or not involved.Normal-weight and overweight participants were less involved in bullying than obese participants; severely obese males were more involved in the double role of bully and victim. Severely obese children and adolescents suffered not only from verbal victimization but also from physical victimization and exclusion from group activities. Weight status categories were not directly related to bullying behaviour; however severely obese males perpetrated more bullying behaviour compared to severely obese females.Obesity and bullying among children and adolescents are of ongoing concern worldwide and may be closely related. Common strategies of intervention are needed to cope with these two social health challenges.

The main aims of this study were to describe change in psychological outcomes for adolescents with anorexia nervosa across two treatments, and to explore predictors of change, including baseline demographic and clinical characteristics, as well as weight gain over time. Participants were 121 adolescents with anorexia nervosa from a two-site (Chicago and Stanford) randomized controlled trial who received either family-based treatment or individual adolescent supportive psychotherapy. Psychological symptoms (i.e., eating disorder psychopathology, depressive symptoms, and self-esteem) were assessed at baseline, end of treatment, 6-month, and 12-month follow-up. Conditional multilevel growth models were used to test for predictors of slope for each outcome. Most psychological symptoms improved significantly from baseline to 12 month follow-up, regardless of treatment type. Depressive symptoms and dietary restraint were most improved, weight and shape concerns were least improved, and self-esteem was not at all improved. Weight gain emerged as a significant predictor of improved eating disorder pathology, with earlier weight gain having a greater impact on symptom improvement than later weight gain. Adolescents who presented with more severe, complex, and enduring clinical presentations (i.e., longer duration of illness, greater eating disorder pathology, binge-eating/purging subtype) also appeared to benefit more psychologically from treatment.

Full Text Available The aim of the study was to evaluate the effects of short-term exercise on total antioxidant status (TAS, lipid hydroperoxide (LOOHs, total oxidative status (TOS and oxidative stress index (OSI in adolescent athletes. A total of 62 adolescent participated in the study. Athletes were trained regularly 3 days a week for 2 hours. All subjects followed a circuit exercise program. Blood samples were collected just before and immediately after the exercise program. Antioxidant status was evaluated by measuring the TAS level in the plasma. Oxidative status was evaluated by measuring the total peroxide level. The percentage ratio of TAS to total peroxide level was accepted as the OSI. Plasma triglyceride, total cholesterol, LDL, HDL and VLDL were measured by automated chemical analyzer using commercially available kits.There was a significant increase in TOS (p<0.05 and OSI (p<0.01 levels and a significant decrease in TAS levels (p<0.01 compared to the resting state. There were no significant changes in LOOHs levels before and after the short-term exercise. After short-term exercise, the balance between oxidative stress and antioxidant status moves towards oxidative stress as a result of increasing oxidants and decreasing antioxidants.
Full Text Available Abstract Background Weight-related issues such as obesity, dieting and eating disorders in adolescents are major public health problems. Moreover, undertaking a diet tends to be common among school children and the reasons for doing so are not always related to weight status. The objectives of the study were to evaluate the role of body mass index (BMI, gender and self-esteem in the adoption of a diet in middle-school Sicilian children. Methods The survey included middle-school children in some Sicilian provinces. Weight status was determined by sex-specific body mass index for age according to the international BMI cut-off proposed by Cole. Classic chi-square test and linear trend chi-square were used to compare percentages. Univariate and multivariate logistic regressions were computed to study the risk of dieting according to weight status (with the underweight group as the reference group, gender, self-esteem adjusted for province. Adjusted odds ratios (ORs and 95% confidence intervals (CI along with associated p-values were furnished. Results The survey showed that 45.2% of the children were of average-weight, 6.6% were underweight, 12.6% were overweight and 2.9% were clinically obese. The missing data were up to 32.8%. Regarding dieting, 26.3% of the children stated that they had been on a diet during the last three months, 56.4% claimed they had not, and 17.2% did not answer. Age was not associated with dieting (p = 0.76. More girls than boys had undertaken a diet (31.4% versus 21.4%, p Conclusions In addition to the relation between dieting and BMI, our results highlight the link between dieting, gender and self-esteem. We underline the importance of interventions within the context of health education in order to improve global self-esteem and to encourage proper eating habits to prevent weight-related health problems.

This study aimed to investigate the relationship between health Related quality of life (HRQOL), motor ability and weight status in children. Two hundred forty children ages 9-11 yr who were selected via multi stage cluster sampling design from primary schools in the Shahre Qods at Tehran, Iran in 2007. HRQOL was assessed by the pediatric quality of life inventory (PedsQL). Motor abilities were determined by a Basic Motor Ability Test (BMAT). Body mass index was calculated to determine weight status. Psychosocial, physical, and total health related qualities of life (all PBMAT variables and weight status. Regardless of motor ability levels, reducing body weight among children is a potential avenue for promoting improved HRQOL. Over weight boys reported significantly worse school performance than over weight girls, suggesting the importance in considering such dimensions in programs aimed at further understanding obesity in children.

Adolescents with intellectual and developmental disabilities (IDD) are at an increased risk of obesity, with up to 55% considered overweight and 31% obese. However, there has been minimal research on weight management strategies for adolescents with IDD. The purpose of this study was to compare the effectiveness of two weight loss diets, an enhanced Stop Light Diet (eSLD) and a conventional diet (CD), and to determine the feasibility of using tablet computers as a weight loss tool in overweight and obese adolescents with IDD. A 2-month pilot intervention was conducted. All participants were randomized to the eSLD or CD and were given a tablet computer that they used to track daily dietary intake and physical activity. Participants and parents met weekly with a registered dietitian nutritionist via video chat on the tablet computer to receive diet and physical activity feedback and education. Twenty participants (45% female, aged 14.9±2.2 years) were randomized and completed the intervention. Participants in both diets were able to lose weight, and there were no significant differences between the eSLD and CD (-3.89±2.66 kg vs -2.22±1.37 kg). Participants were able to use the tablet computer to track their dietary intake 83.4%±21.3% of possible days and to attend 80.0% of the video chat meetings. Both dietary interventions appear to promote weight loss in adolescents with IDD, and the use of tablet computers appears to be a feasible tool to deliver a weight loss intervention in adolescents with IDD.

Objectives. We examined perpetration of bullying among youths in vulnerable groups relative to youths in peer groups not categorized as vulnerable. Methods. Data were collected in 2013 from a large school-based survey of adolescents conducted in Minnesota (n = 122 180). We used the χ2 test and logistic regression to compare measures of perpetration of physical and relational bullying, as well as experiences of victimization and perpetration (or both), across categories of sexual orientation, weight status, and disability status. Results. Rates of physical and relational bullying perpetration were significantly higher among youths in vulnerable groups than among those not in vulnerable groups. With respect to context of victimization experiences, young men and women from vulnerable groups were overrepresented in the group comprising both perpetrators and victims. For example, odds of being both a perpetrator and a victim were 1.41 to 3.22 times higher among gay, lesbian, and bisexual youths than among heterosexual youths. Conclusions. Vulnerable youths, who are prone to peer harassment, may also act as perpetrators of bullying. Prevention strategies should address the particular needs of these populations; targeted programming may be appropriate. PMID:26180987

The consumption of ultra-processed foods may be associated with the development of chronic diseases, both in adults and in children/adolescents. This consumption is growing worldwide, especially in low and middle-income countries. Nevertheless, its magnitude in small, poor cities from the countryside is not well characterized, especially in adolescents. This study aimed to assess the consumption of minimally processed, processed and ultra-processed foods by adolescents from a poor Brazilian city and to determine if it was associated with excess weight, high waist circumference and high blood pressure. Cross-sectional study, conducted at a public federal school that offers technical education together with high school, located in the city of Murici. Adolescents of both sexes and aged between 14-19 years old were included. Anthropometric characteristics (weight, height, waist circumference), blood pressure, and dietary intake data were assessed. Associations were calculated using Poisson regression models, adjusted by sex and age. At total, 249 adolescents were included, being 55.8% girls, with a mean age of 16 years-old. The consumption of minimally processed foods was inversely associated with excess weight (Adjusted Prevalence Ratio: 0.61, 95% Confidence Interval: [0.39-0.96], P = 0.03). Although the consumption of ultra-processed foods was not associated with excess weight, high blood pressure and high waist circumference, 46.2% of the sample reported eating these products more than weekly. Consumption of minimally processed food is inversely associated with excess weight in adolescents. Investments in nutritional education aiming the prevention of chronic diseases associated with the consumption of these foods are necessary.

To identify patterns in adolescents' obesogenic behaviors and their relations to physical and psychological health. A nationally representative sample of 9,174 U.S. adolescents ages 11 to 16 years was surveyed on physical activity (PA), screen-based sedentary behavior (SB), frequency of consumption of healthy and unhealthy food items, weight status, weight control behavior, depression, physical symptoms, body dissatisfaction, overall health, and life satisfaction. Latent class analysis was used to identify patterns of PA, SB, and diet. A model with three latent classes best fit the data: Class 1 with high PA and high fruit and vegetable intake and low SB and intake of sweets, soft drinks, chips, and fries; Class 2 with high SB and high intake of sweets, soft drinks, chips, and fries; and Class 3 with low PA, low fruit and vegetable intake, and low intake of sweets, chips, and fries. Membership in the three classes was related to age, gender, race/ethnicity, and socioeconomic status. In addition, members of Class 1 (26.5%) were more likely to be of normal weight status and to fare well on most of the other health indices; of Class 2 (26.4%) were less likely to be trying to lose weight but scored poorly on the mental health indices; and of Class 3 (47.2%) were less likely to be underweight and reported greater body dissatisfaction. Three prevalent patterns of adolescent obesogenic behaviors were identified and these patterns related to weight status, depression, and other indicators of physical and psychological health.

Under-nutrition, over-nutrition and obesity incidence in relation to environmental diversity and socio-economic influences in adolescents from less urbanized regions of Poland has not been widely studied. To determine the correlation between socio-economic status and incidence of underweight, overweight and obesity in adolescents located in less-urbanized regions of Poland. The study involved 553 adolescents aged 13-18 living in 2 less-urbanized regions of Poland (small towns and villages in the central and north-eastern regions). The sample was randomly chosen. The distinguishing determinants of socio-economic status (SES) included 6 features. The SES index (SESI) was calculated. Low, average and high SESI adolescents were distinguished. Using logistic regression, the odds ratio (OR) of underweight (BMI0.05). The odds ratio of overweight incidence in the average SESI adolescent was 1.73 (95%CI: 0.93, 3.19; p>0.05) and in high SESI adolescents - 1.14 (95%CI: 0.83, 1.57; p>0.05). The odds ratio of obesity incidence in the average SESI adolescent was 0.70 (95%CI: 0.21, 2.34; p>0.05) and in high SESI adolescents - 0.76 (95%CI: 0.40, 1.44; p>0.05). Adjustments for gender, age or region of residence did not significantly change the ORs values or their interpretation. Underweight incidence in adolescents from less urbanized regions of Poland depended on socio-economic status. An adolescent with average socio-economic status was 3 times less likely to be underweight than an adolescent with low socio-economic status. The correlation between socio-economic status and overweight and obesity was not significant.

To apply a new tool to understand the quality of life (QOL) implications of patients' functional status. Results from the Features-Resource Trade-Off Game were used to form utility weights by ranking functional activities by the relative value of achieving independence in each activity compared with all other component activities. The utility weights were combined with patients' actual levels of performance across the same activities to produce QOL-weighted functional status scores and to form "value rulers" to order activities by perceived importance. Persons with severe disabilities living in the community and clinicians practicing in various rehabilitation disciplines. Two panels of 5 consumers with disabilities and 2 panels of 5 rehabilitation clinicians. The 4 panels played the Features Resource Trade-Off Game by using the FIMT(TM) instrument definitions. Utility weights for each of the 18 FIM items, QOL-weighted FIM scores, and value rulers. All 4 panels valued the achievement of independence in cognitive and communication activities more than independence in physical activities. Consequently, the unweighted FIM scores of patients who have severe physical disabilities but relatively intact cognitive skills will underestimate QOL, while inflating QOL in those with low levels of independence in cognition and communication but higher physical function. Independence in some activities is more valued than in others; thus, 2 people with the same numeric functional status score could experience very different QOL. QOL-weighted functional status scores translate objectively measured functional status into its subjective meaning. This new technology for measuring subjective function-related QOL has a variety of applications to clinical, educational, and research practices.

The objective of this study is to update evidence-based best practice guidelines for pediatric/adolescent weight loss surgery (WLS). We performed a systematic search of English-language literature on WLS and pediatric, adolescent, gastric bypass, laparoscopic gastric banding, and extreme obesity published between April 2004 and May 2007 in PubMed, MEDLINE, and the Cochrane Library. Keywords were used to narrow the search for a selective review of abstracts, retrieval of full articles, and grading of evidence according to systems used in established evidence-based models. In light of evidence on the natural history of obesity and on outcomes of WLS in adolescents, guidelines for surgical treatment of obesity in this age group need to be updated. We recommend modification of selection criteria to include adolescents with BMI ≥ 35 and specific obesity-related comorbidities for which there is clear evidence of important short-term morbidity (i.e., type 2 diabetes, severe steatohepatitis, pseudotumor cerebri, and moderate-to-severe obstructive sleep apnea). In addition, WLS should be considered for adolescents with extreme obesity (BMI ≥ 40) and other comorbidities associated with long-term risks. We identified >1,085 papers; 186 of the most relevant were reviewed in detail. Regular updates of evidence-based recommendations for best practices in pediatric/adolescent WLS are required to address advances in technology and the growing evidence base in pediatric WLS. Key considerations in patient safety include carefully designed criteria for patient selection, multidisciplinary evaluation, choice of appropriate procedure, thorough screening and management of comorbidities, optimization of long-term compliance, and age-appropriate fully informed consent.

Purpose The purpose of this study was to document the prevalence of harassment on the basis of weight, race/ethnicity, and socioeconomic status, as well as sexual harassment, among a diverse population of adolescents. Specifically, this study examined rates of each type of harassment reported across groups within the corresponding sociodemographic category (e.g., racial/ethnic category differences in prevalence of racial harassment), and also explored patterns of “cross-harassment” (i.e., differences in prevalence of each harassment type across all other sociodemographic characteristics). Methods Data from EAT 2010 (Eating and Activity in Teens) were used for the current study. The sample was comprised of 2,793 adolescents (53% female; 81% non-white). Regression analyses were conducted to yield prevalence estimates of each type of harassment in each demographic and BMI category. Results Weight- and race-based harassment (35.3% and 35.2%, respectively) were most prevalent, followed by sexual harassment (25.0%) and SES-based harassment (16.1%). Overweight and obese adolescents reported disproportionately higher rates of all forms of harassment than did normal-weight and underweight adolescents. In addition, Asian and mixed-/other-race adolescents were more vulnerable to harassment overall as compared to those from other racial/ethnic groups. Conclusions Harassment experiences are prevalent among adolescent boys and girls. Differential rates of each type of harassment are reported across groups within the corresponding sociodemographic category, but a pattern of “cross-harassment” also is evident, such that differences in prevalence of each type of harassment emerge across a variety of sociodemographic characteristics. Adolescents from various intersecting sociodemographic and weight-status groups are particularly vulnerable to certain types of harassment. PMID:23566562

Full Text Available ABSTRACT Objective To analyze the prevalence and factors associated with breakfast skipping among adolescents. Methods Cross-sectional study, with adolescents aged 10-17 years, evaluated between 2009 and 2011, belonging to a cohort study in the Central-West region of Brazil. Breakfast skipping was considered as not having breakfast every day. Demographic, socioeconomic, and lifestyle factors were evaluated through a questionnaire. Anthropometric assessment included measurement of weight and height, which were used to classify weight status using body mass index. Poisson regression was used to assess the association of breakfast skipping with demographic and socioeconomic variables, lifestyle factors, and weight status. Results Among 1,716 Brazilian adolescents evaluated, 36.2% reported not consuming breakfast every day, with the highest prevalence among girls (p=0.03. After adjusting for age and economic class, breakfast skipping was associated with not consuming breakfast with parents and morning shift at school, in both genders, and with obesity only in boys. Lifestyle factors such as alcohol consumption, physical activity, diet quality, and smoking were not associated with skipping breakfast. Conclusion The omission of breakfast was observed in more than a third of adolescents, being associated with demographic and lifestyle factors. In the public health perspective, the importance of encouraging the consumption of this meal is highlighted, with actions involving the school environment and the family.

The aim of this study was to investigate the prevalence of overweight/obesity among parents of children entering childhood obesity treatment and to evaluate changes in the parents' weight statuses during their child's treatment. The study included parents of 1,125 children and adolescents aged 3-22 years, who were enrolled in a multidisciplinary childhood obesity treatment program. At baseline, weight and height of the parents were obtained by self-reported information and parental body mass index (BMI) was calculated. Weight and height of the children were measured in the clinic and BMI standard deviation scores were calculated. Furthermore, anthropometric data from parents of 664 children were obtained by telephone interview after a mean of 2.5 years of treatment (ranging 16 days to 7 years), and changes in parental BMI were analyzed. Data on changes in BMI were available in 606 mothers and 479 fathers. At baseline, the median BMI of the mothers was 28.1 kg/m2 (range: 16.9-66.6), and the median BMI of the fathers was 28.9 kg/m2 (range: 17.2-48.1). Seventy percent of the mothers and 80% of the fathers were overweight or obese at the time of their child's treatment initiation. Both the mothers and fathers lost weight during their child's treatment with a mean decrease in BMI in the mothers of 0.5 (95% CI: 0.2-0.8, p = 0.0006) and in the fathers of 0.4 (95% CI: 0.2-0.6, p = 0.0007). Of the overweight/obese parents, 60% of the mothers and 58% of the fathers lost weight during their child's treatment. There is a high prevalence of overweight/obesity among parents of children entering childhood obesity treatment. Family-based childhood obesity treatment with a focus on the child has a positive effect on parental BMI with both mothers and fathers losing weight. ClinicalTrials.gov NCT00928473.

The aim was to identify the association of iron status with educational performance and intelligence of adolescents. This was a cross sectional comparative study among adolescents aged 13-15 years. Each iron deficient student was matched with an iron sufficient student from the same school, class and sex. Iron status was based on haemoglobin and serum ferritin levels. The marks for mathematics, science, Sinhala language and social science were considered to assess educational performance. Intelligence was measured by Raven's Standard progressive matrices. All the possible confounders and effect modifiers were considered. Home visits to a sub-sample checked the quality of data. The final analysis included 188 students (94 matched pairs). Neither educational performance nor intelligence showed significant associations with the iron status. The severity of the iron deficiency did not relate to these cognitive variables either. Twenty-three and 8 co-variables showed statistically significant associations with educational performance and intelligence respectively. Following a multiple regression analysis intelligence, the enthusiasm of the student towards learning, occupational ambition, household possession, problems at home and private tuition for mathematics were key factors predicting educational performance. Stunting and educational level of the mother were important factors influencing intelligence. Iron status does not play a major role in educational performance and intelligence of school going adolescents. Several factors affect educational performance and intelligence. This study highlights the difficulty in extrapolating the findings of similar studies to different ecological settings.

This study examined the associations of subjective social status (SSS) with physical activity (PA) and sedentary time (ST) among adolescents. The study population consisted of 420 Finnish adolescents aged 13 to 14 years. The adolescents reported their own SSS within their school (school SSS) and their family's social position within society (society SSS) based on the youth version of the Subjective Social Status Scale. Adolescents' moderate- to vigorous-intensity physical activity (MVPA) and ST were measured objectively by accelerometers and analyzed separately for the whole day and the school day. The associations between SSS and MVPA and ST outcomes were analyzed using multilevel modeling. School SSS was positively associated with whole-day MVPA and negatively associated with school-time ST. Society SSS was not significantly associated with objectively measured MVPA or ST. Both MVPA and ST are important behavioral determinants of health. As an important correlate of MVPA and ST, school SSS should be addressed by providers when discussing obesity risk and healthy behaviors with adolescents.

Racial disparities in childhood asthma prevalence increased after the 1990s. Obesity, which also varies by race/ethnicity, is an asthma risk factor but its contribution to asthma prevalence disparities is unknown. We analyzed nationally representative National Health Examination and Nutrition Survey data for 2-19 year olds with logistic regression and decomposition analyses to assess the contributions of weight status to racial disparities in asthma prevalence, controlling for sex, age, and income status. From 1988-1994 to 2011-2014, asthma prevalence increased more among non-Hispanic black (NHB) (8.4% to 18.0%) than non-Hispanic white (NHW) youth (7.2% to 10.3%). Logistic regression showed that obesity was an asthma risk factor for all groups but that a three-way "weight status-race/ethnicity-time" interaction was not significant. That is, weight status did not modify the race/ethnicity association with asthma over time. In decomposition analyses, weight status had a small contribution to NHB/NHW asthma prevalence disparities but most of the disparity remained unexplained by weight status or other asthma risk factors (sex, age and income status). NHB youth had a greater asthma prevalence increase from 1988-1994 to 2011-2014 than NHW youth. Most of the racial disparity in asthma prevalence remained unexplained after considering weight status and other characteristics. Published by Elsevier Inc.

To determine the correlation between birth weight and simple obesity, blood lipids, blood glucose and blood pressure from childhood to adolescence. A vertical sectional survey on 193 children aged 7 - 11 years was performed in 1996. A questionnaire consisting of items on environmental factors and lifestyle, physical examination and biochemical assessment was conducted at baseline and the 9th year of follow-up. The incidence of obesity and over-weight in childhood in high (6.1%) and low birth-weight group (5.6%) was higher than that in normal birth-weight group (2.8%), but did not reach statistic significance; The levels of body mass index in adolescence in high and low birth-weight group were significantly higher than that in normal birth-weight group (P = 0.002 and 0.009, respectively), and the incidence of obesity and over-weight in adolescence was significantly higher in high (33.3%) and low birth-weight group (38.9%) than that in normal birth-weight group (16.2%, P = 0.025 and 0.020, respectively). There were no significant differences in the levels of blood glucose, blood lipids and blood pressure between different birth weight groups (all, P > 0.05). Intrauterine growth is linked to physical growth during childhood and adolescence. Nutritional guidance in pregnant phase may help to control the increased prevalence of overweight and obesity in children and adolescent.

To use epidemiological data and a standardized economic model to compare projected costs for obesity prevention in late adolescence accrued using a cross-sectional weight classification for selecting adolescents at age 15 years compared with a longitudinal classification. All children born in a Swedish county (population 440 000) in 1991 who participated in all regular measurements of height and weight at ages 5, 10 and 15 years (n=4312) were included in the study. The selection strategies were compared by calculating the projected financial load resulting from supply of obesity prevention services from providers at all levels in the health care system. The difference in marginal cost per 1000 children was used as the primary end point for the analyses. Using the cross-sectional selection strategy, 3.8% of adolescents at age 15 years were selected for evaluation by a pediatric specialist, and 96.2% were chosen for population-based interventions. In the trajectory-based strategy, 2.4% of the adolescents were selected for intensive pediatric care, 1.4% for individual clinical interventions in primary health care, 14.0% for individual primary obesity prevention using the Internet and 82.1% for population-based interventions. Costs for the cross-sectional selection strategy were projected to USD463 581 per 1000 adolescents and for the trajectory-based strategy were USD 302 016 per 1000 adolescents. Using projections from epidemiological data, we found that by basing the selection of adolescents for obesity prevention on weight trajectories, the load on highly specialized pediatric care can be reduced by one-third and total health service costs for obesity management among adolescents reduced by one-third. Before use in policies and prevention program planning, our findings warrant confirmation in prospective cost-benefit studies.
Full Text Available Limited data exist regarding the association between binge eating and quality of life (QOL in obese adolescent girls and boys. We, therefore, studied binge eating and QOL in 158 obese (BMI ≥ 95th percentile adolescents (14.5 ± 1.4 years, 68.0% female, 59% African-American prior to weight-loss treatment. Youth completed an interview to assess binge eating and a questionnaire measure of QOL. Controlling for body composition, binge eating youth (n = 35, overall, reported poorer QOL in domains of health, mobility, and self-esteem compared to those without binge eating ( ps < 0.05. Also, girls, overall, reported poorer QOL than boys in activities of daily-living, mobility, self-esteem, and social/interpersonal functioning (ps < 0.05. Girls with binge eating reported the greatest impairments in activities of daily living, mobility, self-esteem, social/interpersonal functioning, and work/school QOL (ps < 0.05. Among treatment-seeking obese adolescents, binge eating appears to be a marker of QOL impairment, especially among girls. Prospective and treatment designs are needed to explore the directional relationship between binge eating and QOL and their impact on weight outcomes.

Anorexia nervosa is a psychiatric disorder of unknown etiology. Understanding associations between behavior and neurobiology is important in treatment development. Using a novel monetary reward task during functional magnetic resonance brain imaging, the authors tested how brain reward learning in adolescent anorexia nervosa changes with weight restoration. Female adolescents with anorexia nervosa (N=21; mean age, 16.4 years [SD=1.9]) underwent functional MRI (fMRI) before and after treatment; similarly, healthy female control adolescents (N=21; mean age, 15.2 years [SD=2.4]) underwent fMRI on two occasions. Brain function was tested using the reward prediction error construct, a computational model for reward receipt and omission related to motivation and neural dopamine responsiveness. Compared with the control group, the anorexia nervosa group exhibited greater brain response 1) for prediction error regression within the caudate, ventral caudate/nucleus accumbens, and anterior and posterior insula, 2) to unexpected reward receipt in the anterior and posterior insula, and 3) to unexpected reward omission in the caudate body. Prediction error and unexpected reward omission response tended to normalize with treatment, while unexpected reward receipt response remained significantly elevated. Greater caudate prediction error response when underweight was associated with lower weight gain during treatment. Punishment sensitivity correlated positively with ventral caudate prediction error response. Reward system responsiveness is elevated in adolescent anorexia nervosa when underweight and after weight restoration. Heightened prediction error activity in brain reward regions may represent a phenotype of adolescent anorexia nervosa that does not respond well to treatment. Prediction error response could be a neurobiological marker of illness severity that can indicate individual treatment needs.

To examine prevalence of weight misperception (incongruence between one's perceived weight status and one's actual weight status) and disordered weight control behaviors (DWCBs; unhealthy behaviors aiming to control or modify weight), associations between weight misperception and DWCBs, and temporal trends in prevalence and associations among adolescents with overweight and obesity from 1999 to 2013. Self-reported data from eight biennial cycles (1999-2013) of the cross-sectional national Youth Risk Behavior Survey were used in analyses restricted to respondents with overweight/obesity. Data on weight status perception, use of fasting, purging, and diet pills to control weight, sex, race/ethnicity, and grade in school were used in multivariate logistic regression models. Among U.S. high school students with overweight and obesity, no linear temporal trends were detected for prevalence of weight misperception, fasting, or purging between 1999 and 2013, while a significant linear decrease was observed for prevalence of diet pill use between 1999 and 2013 (b=-0.81, pfasting to control weight among males. No significant changes over time in associations of weight misperception with fasting or purging were observed, though the association between weight misperception and diet pill use weakened somewhat across 1999-2013. In the context of increasing prevalence of overweight and obesity, weight misperception appears to be a robust protective factor for DWCBs. Copyright © 2017. Published by Elsevier Ltd.
Conclusions: Omega-3 status was associated with weight status, particularly in older women but not in men. These results suggest the need for sex-based intervention trials to examine the role of dietary intake and/or supplementation of LCn-3PUFA in weight management of older adults.

The objective of this study was to assess low-risk very low birth weight (VLBW) children, before the era of modern neonatal intensive care in Turkey, during adolescence. Forty-one VLBW adolescents were compared with 40 adolescents who had normal birth weight. The physical and neuromotor development, educational achievement and psychosocial status were assessed at a mean age of 17 +/- 1.6 years. VLBW adolescents were shorter than normal birth weight adolescents (p = 0.01). A major neurological abnormality (cerebral palsy) was seen in 12% and a minor neurological abnormality (tremor, coordination, behavioral and speech disorders) in 17%. VLBW adolescents had higher rates of visual problems (56% vs. 5%). School failure was present in 27%. There were no differences in behavioral problems or quality of life between the two groups, but VLBW adolescents did have a lower self-esteem score. Neurodevelopment and growth sequelae were a significant problem in VLBW adolescents. As early intervention might help to prevent or ameliorate potential problems, long-term follow-up is essential.

To compare obese and non-obese adolescents in terms of their salivary cortisol response to the Trier Socia l Stress Test ( TSST). This is a cross - sectional study involving 41 healthy adolescents aged 12-14 years in the city of Shenyang, China. The TSST response was determined using salivary cortisol measurements, and measurements were repeated after the test period. Repeated-measures ANOVA was performed to compare salivary cortisol levels between groups. The male group comprised of 16 individuals (10 obese and 6 non-obese), and the female group comprised 25 individuals ( 13 obese and 12 non-obese). ANOVA with repeated measures demonstrated that weight status (obese or non-obese) had a significant main effect on the measures of salivary cortisol levels during the TSST among females but not males. The finding suggested that weight status is associated with cortisol response to psychological stress among Chinese adolescent girls.

Children with obesity experience stigma stemming from stereotypes, one such stereotype is that people with obesity are "sloppy" or have poor manners. Teaching children "proper table manners" has been proposed as an obesity prevention strategy. Little is known about the association between children's weight status and table manners. To examine correlates of child table manners and to examine the association of child table manners with child obese weight status and prospective change in child body mass index z-score (BMIz). Mother-child dyads (N = 228) participated in a videotaped laboratory eating task with cupcakes. Coding schemes to capture child table manners (making crumbs, chewing with mouth open, getting food on face, shoving food in mouth, slouching, and getting out of seat), and maternal attentiveness to child table manners, were reliably applied. Anthropometrics were measured at baseline and at follow-up two years later. Regression analyses examined the association of participant characteristics with child table manners, as well as the associations of child table manners with child obese weight status, and prospective change in BMIz/year. Predictors of poorer child table manners were younger child age, greater cupcake consumption, and greater maternal attentiveness to child table manners. Poorer child table manners were not associated with child obese (vs. not) weight status, but were associated with a prospective decrease in BMIz/year in children with overweight/obesity. Obesity interventions to improve table manners may be perpetuating unfavorable stereotypes and stigma. Future work investigating these associations is warranted to inform childhood obesity guidelines around table manners. Copyright © 2018 Elsevier Ltd. All rights reserved.

Full text: Studies have indicated that lower birth weight is associated with lower body mass index, but the use of birth weight in predicting later nutritional status and adiposity remains inconsistent. Hence, this paper aimed to examine the relationship between birth weight and nutritional status with body composition among Malaysian children. This study is part of the Nutritional Survey of Malaysian Children, which is part of the four-country South East Asian Nutrition Surveys (SEANUTS). Subjects comprising 398 boys and 389 girls from the main ethnic groups, namely Malays, Chinese, Indians, Sabah and Sarawak natives, were recruited using a stratified random sampling. Anthropometric measurements comprised body weight, height, waist circumference (WC) and body fat (BF). Body mass index (BMI), fat mass index (FMI) and fat-free mass index (FFMI) adjusted with height were included, and birth weight was obtained by parental report. Nutritional status such as weight-for-age (WAZ), height-for-age (HAZ) and BMI-for-age (BAZ) were determined using the WHO growth reference for 5–19 years. Physical activity level was assessed using the Physical Activity Questionnaire for Children. Mean birth weight, height, weight, and BF were 3.1±0.5kg, 128.0±8.1cm, 28.4±8.9kg, and 27.9±9.1% respectively. Boys (20.4±4.2kg) had higher FFM (p 4.0kg) (WAZ: 0.51±1.35; HAZ: -0.07 ± 0.67) at p<0.05. Besides, there were significant differences in weight, height, BAZ, FFM and FFMI between birth weight groups. Birth weight has weak correlation (p<0.01) with FFM (r = 0.22), WAZ (r = 0.21), HAZ (r = 0.20), BAZ (r = 0.18) and WC (r = 0.14). After adjusting for covariates, we found that higher birth weight was associated with significant higher values in all anthropometric measurements (p<0.01), especially WC (β = 2.82, p<0.001). Multiple regression analysis also indicated that birth weight positively predicted later nutritional status; 1kg increase in birth weight predicted 0.70, 0.46, and 0

Malnutrition that occurs during adolescence has important consequences for the future growth and development of the individual, particularly in girls in developing countries. Besides limiting growth, adolescent malnutrition has important consequences for society. Despite this, there is a lack of information on the nutritional status of adolescent girls in Ethiopia. This study was therefore performed to help redress this lack of data and to provide information for future improvements by health planners and policy makers. A comparative cross-sectional study design was employed to determine the urban-rural disparity in nutritional status of adolescent school girls in the Mizan district in south-western Ethiopia. A two-stage sampling procedure was used to randomly select 622 adolescent girls, 311 each from urban and rural locations. Trained field workers used structured questionnaires to obtain the desired information from the respondents. Anthropometric measurements of height and weight were collected using standard procedures and appropriate quality control measures. Height-for-age Z-scores and body mass index (BMI)-for-age Z-scores were generated using AnthroPlus software. The independent sample t-test and χ2 test were used to determine statistical significance. There were no significant differences in the ages or physical activities of the two populations of girls studied. Consumption of cereal, vegetables, sweets, sugars, fats, meat, and eggs was similar between the two groups, although slight differences were found with regard to legumes, milk, and fruit consumption. No significant differences were found in the prevalence of mild underweight girls and overweight girls in the urban and rural groups (26.5% vs 22.3% and 7.5% vs 5.2%, respectively). Significant stunting was, however, present in the rural population (40.9% vs. 17.8% in the urban group). Although overall lower than the reference data provided by WHO, the mean BMI-for-age Z-scores and height-for-age Z

The continued existence of undernutrition, associated with a steady increase in the prevalence of overweight and obesity in children and adolescents, necessitates identification of factors contributing to this double burden of disease, in order for effective treatment and prevention programmes to be planned. To determine the nutritional status of 13-15-year-old children in Bloemfontein and its association with socioeconomic factors. Bloemfontein, Free State Province, South Africa (2006). This was a cross-sectional analytical study. Randomly selected children (n = 415) completed structured questionnaires on socioeconomic status. The children's weight and height were measured and body mass index-for-age and height-for-age z-scores were computed according to World Health Organization growth standards in order to determine the prevalence of underweight, overweight, obesity and stunting. Waist circumference was measured to classify the children as having a high or very high risk for metabolic disease. Of the 415 children who consented to participate in the study, 14.9% were wasted and 3.4% were severely wasted. Only 6% of the children were overweight/obese. Significantly more boys (23.0%) were wasted than girls (10%) and severe stunting was also significantly higher in boys than in girls (10.3% and 4.2%, respectively). Children whose parents had graduate occupations were significantly more overweight/obese than those with parents working in skilled occupations. Stunting was significantly higher in low (31.4%) and medium (30.4%) socioeconomic groups compared to the high socioeconomic group (18.1%). A coexistence of underweight and overweight was found and gender and parental occupation were identified as being predictors of nutritional status.

Introduction: This study aims to assess the associated factors of physical inactivity among Iranian children and adolescents at national level. The second objective is to assess the relationship of physical inactivity with anthropometric measures. Methods: Along with a national surveillance program, this survey on weight disorders was conducted among a nationally-representative sample of Iranian children and adolescents, aged 6-18 years. Students were selected by multi-stage cluster sampling from rural and urban areas of 30 provinces of Iran. The Physical Activity Questionnaire for Adolescents (PAQ-A) was used to assess physical activity (PA). Using PAQ-A instrument, PA of past week categorized as; low PA level, that included those who scored between 1 to 1.9 on the PAQ-A instrument and high PA level that included participants with estimated scores between 2-5 PAQ-A. Results: Participants were 23183 school students (50.8% boys) with a mean age of 12.55 ± 3.3 years, without significant difference in terms of gender. Totally, 23.48% of participants (13.84% of boys and 33.42% of girls) were physically inactive. In multivariate logistic regression model, with increased age in children and adolescence, the odds of a physically inactivity increased (OR: 1.08; 95% CI: 1.07-1.10). The odds of prevalence of both obesity and underweight were high in children and adolescents with low PA. There was a decreasing trend in PA in higher school grades. Conclusion: We found a considerably high prevalence of physical inactivity in Iranian children and adolescents, with higher rates among girls and older ages. However, we did not find correlation between PA and socioeconomic status (SES). Because of the positive relationship between PA and ST, future studies should consider the complex interaction of these two items. Multidisciplinary policies should be considered in increasing PA programs among children and adolescents.

Fifty-seven percent of children with poor language skills are affected by socio-emotional problems. Despite the importance of language skills to interpersonal functioning and school performance, relatively little is known about how they affect self-esteem in adolescence. Data on youth at high risk for language problems (e.g. those born extremely low birth weight (ELBW; self-esteem during adolescence (12-16 years) in individuals born at ELBW ( N = 138) or normal birth weight (NBW; >2500 grams) ( N = 111). Participants' language skills were assessed using the Verbal Scale of the Wechsler Intelligence Scale for Children-Revised and the Token Test at age 8. In adolescence, participants completed the Harter Self-Perception Profile for Adolescents. Birth weight status was found to moderate associations between childhood language and adolescent global self-esteem (Token Test ( p = .006), Verbal Intelligence Quotient ( p = .033)) such that better language skills were associated with higher self-esteem in adolescent ELBW survivors, but not in NBW participants. Language skills may play a protective role in the development and maintenance of self-esteem in ELBW youth and could be an important target for optimizing their functioning, particularly before transitioning to the critical adolescent period.

Ability to accurately estimate calories is important for weight management, yet few studies have investigated whether individuals can accurately estimate calories during exercise or in a meal. The objective of this study was to determine if accuracy of estimation of moderate or vigorous exercise energy expenditure and calories in food is associated with body weight class or weight loss status. Fifty-eight adults who were either normal weight (NW) or overweight (OW), and either attempting (WL) or not attempting weight loss (noWL), exercised on a treadmill at a moderate (60% HRmax) and a vigorous intensity (75% HRmax) for 25 min. Subsequently, participants estimated the number of calories they expended through exercise and created a meal that they believed to be calorically equivalent to the exercise energy expenditure. The mean difference between estimated and measured calories in exercise and food did not differ within or between groups after moderate exercise. After vigorous exercise, OW-noWL overestimated energy expenditure by 72% and overestimated the calories in their food by 37% (P food compared with both WL groups (P food. There was a wide range of underestimation and overestimation of calories during exercise and in a meal. Error in calorie estimation may be greater in overweight adults who are not attempting weight loss.

For an industrialized nation, obesity rates in South Korea are extremely low. Yet, reflecting an extremely fat-averse, thin-positive society, efforts to lose weight are now reportedly very common. Since the 1980s, South Korea has experienced an increasingly flexible and insecure labor market which was exacerbated by the 1997 economic recession. In this social and economic setting, body shape and weight status, as human capital, may have gained significant bargaining power in the labor market. Consequently, we propose that Koreans, particularly those who are employed in "stable" jobs (i.e., non-manual and regular jobs), would increasingly engage in intense weight management and reduction activities even when not technically overweight or obese as a means to job security and upward mobility. Using nationally-representative data from the Korean Nutrition and Health Examination Survey (KNHANES), we identify the changing role of weight concerns versus actual body weight in predicting South Korean efforts to lose weight between 2001 (KNHANES-phase 1) and 2007-2009 (phase 4). The patterns were examined by occupation type (manual and non-manual jobs) and status (regular and non-regular jobs). Oaxaca decomposition analysis supported that people's perception of being "fat," rather than actual weight status, was crucial to explaining accelerated weight management efforts in South Korea over the decade (coef. = 0.062 and p-value < .0001 for male with regular work; coef. = 0.031 and p-value = .002 for female with regular work). Occupation status, rather than employment in itself, mattered. Job stability predicted increased effort; the pattern of change through time suggests efforts to invest high levels of effort in appearance positively impacts both employment opportunity and stability.

This study examined longitudinal associations of prenatal exposures as well as childhood familial experiences with obesity status from ages 10 to 18. Hierarchical generalized linear modeling (HGLM) was applied to examine 5,156 adolescents from the child sample of the 1979 National Longitudinal Survey of Youth (NLSY79). Higher maternal weight, maternal smoking during pregnancy, lower maternal education, and lack of infant breastfeeding were contributors to elevated adolescent obesity risk in early adolescence. However, maternal age, high birth weight of child, and maternal annual income exhibited long-lasting impact on obesity risk over time throughout adolescence. Additionally, childhood familial experiences were significantly related to risk of adolescent obesity. Appropriate use of family rules in the home and parental engagement in children's daily activities lowered adolescent obesity risk, but excessive television viewing heightened adolescent obesity risk. Implementation of consistent family rules and parental engagement may benefit adolescents at risk for obesity.

Full Text Available Background and Objectives: A large number of children are afflicted by thalassemia in India which may significantly impact their quality of life (QOL; hence, we hypothesized that there exists a strong relationship between socioeconomic status and QOL. We thus designed this study to assess QOL in adolescents diagnosed with β thalassemia major and its association with socioeconomic status. Further, we also compared the QOL and socioeconomic status between thalassemic and nonthalassemic adolescents. Materials and Methods: We recruited 35 adolescents diagnosed with β thalassemia major and 35 nonthalassemics in the age group of 10-18 years who matched in age, sex, and socioeconomic status. Selected cases and their parents were administered using PedsQL 4.0 India/Hindi questionnaire to assess QOL and modified Kuppuswamy scale to assess socioeconomic status. Results: Almost half of the thalassemic adolescents, i.e., 51.4% had poor QOL, whereas 48.6% of adolescents in control group had high QOL. There was no statistically significant association between QOL and socioeconomic status in both groups. It was observed that the difference between QOL and socioeconomic class though not significant but was more pronounced in study group (P = 0.114 than control group (P = 0.594. The receiver operating characteristic curve for QOL parameters indicated that social domain was the major contributor to poor QOL in thalassemics. Conclusion: Our study showed that thalassemic adolescents had significantly poor QOL, social domain being the major contributor as compared to nonthalassemics. We propose that provision of subsidized organized care can negate the impact of poor socioeconomic status on QOL of thalassemics.

The aim of this study was to investigate if baseline motor competence, weight status and sports participation in early childhood predict sports participation two years later. longitudinal study. In 2010, motor competence (object control and locomotor skills), weight status and sports participation were assessed in 292 children between three and five years-of-age. In 2012, sports participation was re-evaluated in 206 of the original 292 children. Logistic regression was implemented to examine if initial sports participation, motor competence and weight status would predict sports participation two years later. In the final model, sports participation in 2010 (OR=9.68, CI: 3.46 to 27.13) and locomotor skills (OR=1.21, CI: 1.01 to 1.46) significantly predicted sports participation after two years. These results suggest that initial sports participation and more advanced locomotor skills in preschool years may be important to promote continued participation in sports across childhood.

To investigate whether anorexia nervosa (AN), bulimia nervosa (BN), binge eating disorder (BED), and other specified feeding and eating disorders (OSFED), including purging disorder (PD), subthreshold BN, and BED at ages 14 and 16 years, are prospectively associated with later depression, anxiety disorders, alcohol and substance use, and self-harm. Eating disorders were ascertained at ages 14 and 16 years in 6,140 youth at age 14 (58% of those eligible) and 5,069 at age 16 (52% of those eligible) as part of the prospective Avon Longitudinal Study of Parents and Children (ALSPAC). Outcomes (depression, anxiety disorders, binge drinking, drug use, deliberate self-harm, weight status) were measured using interviews and questionnaires about 2 years after predictors. Generalized estimating equation models adjusting for gender, socio-demographic variables, and prior outcome were used to examine prospective associations between eating disorders and each outcome. All eating disorders were predictive of later anxiety disorders. AN, BN, BED, PD, and OSFED were prospectively associated with depression (respectively AN: odds ratio [OR] = 1.39, 95% CI = 1.00-1.94; BN: OR = 3.39, 95% CI = 1.25-9.20; BED: OR = 2.00, 95% CI = 1.06-3.75; and PD: OR = 2.56, 95% CI = 1.38-4.74). All eating disorders but AN predicted drug use and deliberate self-harm (BN: OR = 5.72, 95% CI = 2.22-14.72; PD: OR = 4.88, 95% CI = 2.78-8.57; subthreshold BN: OR = 3.97, 95% CI = 1.44-10.98; and subthreshold BED: OR = 2.32, 95% CI = 1.43-3.75). Although BED and BN predicted obesity (respectively OR = 3.58, 95% CI = 1.06-12.14 and OR = 6.42, 95% CI = 1.69-24.30), AN was prospectively associated with underweight. Adolescent eating disorders, including subthreshold presentations, predict negative outcomes, including mental health disorders, substance use, deliberate self-harm, and weight outcomes. This study highlights the high public health and clinical burden of eating disorders

Full Text Available [b][/b]Introduction. Under-nutrition, over-nutrition and obesity incidence in relation to environmental diversity and socio-economic influences in adolescents from less urbanized regions of Poland has not been widely studied. Objective. To determine the correlation between socio-economic status and incidence of underweight, overweight and obesity in adolescents located in less-urbanized regions of Poland. Material and methods. The study involved 553 adolescents aged 13–18 living in 2 less-urbanized regions of Poland (small towns and villages in the central and north-eastern regions. The sample was randomly chosen. The distinguishing determinants of socio-economic status (SES included 6 features. The SES index (SESI was calculated. Low, average and high SESI adolescents were distinguished. Using logistic regression, the odds ratio (OR of underweight (BMI0.05. The odds ratio of overweight incidence in the average SESI adolescent was 1.73 (95%CI: 0.93, 3.19; p>0.05 and in high SESI adolescents – 1.14 (95%CI: 0.83, 1.57; p>0.05. The odds ratio of obesity incidence in the average SESI adolescent was 0.70 (95%CI: 0.21, 2.34; p>0.05 and in high SESI adolescents – 0.76 (95%CI: 0.40, 1.44; p>0.05. Adjustments for gender, age or region of residence did not significantly change the ORs values or their interpretation. Conclusions. Underweight incidence in adolescents from less urbanized regions of Poland depended on socio-economic status. An adolescent with average socio-economic status was 3 times less likely to be underweight than an adolescent with low socio-economic status. The correlation between socio-economic status and overweight and obesity was not significant.

The purpose of this study was to determine the prevalence of overweight and obesity and to examine the effects of actual weight status, perceived weight status and body satisfaction on self-esteem and depression in a high school population in Turkey. A cross-sectional survey of 2101 tenth-grade Turkish adolescents aged 15-18 was conducted. Body mass index (BMI) was calculated using weight and height measures. The overweight and obesity were based on the age- and gender-specific BMI cut-off points of the International Obesity Task Force values. Self-esteem was measured using the Rosenberg Self-Esteem Scale, and depression was measured using Children's Depression Inventory. Logistic regression analysis was used to examine relationships among the variables. Based on BMI cut-off points, 9.0% of the students were overweight and 1.1% were obese. Logistic regression analysis indicated that (1) being male and being from a higher socio-economical level were important in the prediction of overweight based on BMI; (2) being female and being from a higher socio-economical level were important in the prediction of perceived overweight; (3) being female was important in the prediction of body dissatisfaction; (4) body dissatisfaction was related to low self-esteem and depression, perceived overweight was related only to low self-esteem but actual overweight was not related to low self-esteem and depression in adolescents. The results of this study suggest that school-based adolescents in urban Turkey have a lower risk of overweight and obesity than adolescents in developed countries. The findings of this study suggest that psychological well-being of adolescents is more related to body satisfaction than actual and perceived weight status is.

Based on year 2000 Centers for Disease Control and Prevention growth charts, approximately 17% of children and adolescents aged 2 to 19 years in the United States have obesity, and almost 32% of children and adolescents are overweight or have obesity. Obesity in children and adolescents is associated with morbidity such as mental health and psychological issues, asthma, obstructive sleep apnea, orthopedic problems, and adverse cardiovascular and metabolic outcomes (eg, high blood pressure, abnormal lipid levels, and insulin resistance). Children and adolescents may also experience teasing and bullying behaviors based on their weight. Obesity in childhood and adolescence may continue into adulthood and lead to adverse cardiovascular outcomes or other obesity-related morbidity, such as type 2 diabetes. Although the overall rate of child and adolescent obesity has stabilized over the last decade after increasing steadily for 3 decades, obesity rates continue to increase in certain populations, such as African American girls and Hispanic boys. These racial/ethnic differences in obesity prevalence are likely a result of both genetic and nongenetic factors (eg, socioeconomic status, intake of sugar-sweetened beverages and fast food, and having a television in the bedroom). To update the 2010 US Preventive Services Task Force (USPSTF) recommendation on screening for obesity in children 6 years and older. The USPSTF reviewed the evidence on screening for obesity in children and adolescents and the benefits and harms of weight management interventions. Comprehensive, intensive behavioral interventions (≥26 contact hours) in children and adolescents 6 years and older who have obesity can result in improvements in weight status for up to 12 months; there is inadequate evidence regarding the effectiveness of less intensive interventions. The harms of behavioral interventions can be bounded as small to none, and the harms of screening are minimal. Therefore, the USPSTF

The prevalence of overweight and obesity among children is on the rise worldwide. Prior studies find that parents' child-feeding practices are associated with child weight status and the efficacy of specific parental child-feeding practices can be moderated by parenting styles. In the current longitudinal study, we examined the associations between child-feeding practices and weight status changes over 1 year among a sample of school-aged children in Taiwan. In autumn 2008, a child-feeding questionnaire and parenting-style questionnaire were administered to parents of the second and fourth graders in an elementary school in Taiwan. The weight and height of the students were measured by a trained school nurse in 2008 and again in 2009. An elementary school in central Taiwan. A total of 465 parent-child pairs were included in the analysis. Using a gender- and age-adjusted BMI classification scheme issued by the Taiwan Department of Health, 29·2 % of the students were considered overweight at the 2009 measurement. Controlling for 2008 weight status revealed moderating effects of parenting style on the relationship between child-feeding practices and child weight status. Both authoritative and authoritarian mothers might monitor their children's dietary intake; however, the effectiveness of this practice was better, in terms of weight status control, among the authoritative mothers. Findings suggest that parenting styles have a moderating effect on specific parental child-feeding practices. Parenting styles and parent's feeding practices could be an important focus for future public health interventions addressing the rising childhood obesity epidemic.

This study investigated (1) whether involvement in bullying as a bully, victim or bully-victim was associated with objectively measured overweight or underweight, or whether it was related to weight misperception (i.e., inaccurate perceptions), and (2) whether appearance-specific feedback mediated the relationship between bullying and weight misperception. In Stage 1, 2782 adolescents aged 11-16 years from British secondary schools were screened for peer bullying and victimisation. In Stage 2, 411 adolescents with weight and height data (objective n = 319, self-report n = 92) also self-reported on their weight perception and appearance-specific feedback. Neither bullying nor victimisation were related to objective underweight or overweight. Victims were at increased odds of overweight misperception, while bully-victims were at increased odds of underweight misperception. Additionally, there was an indirect effect of appearance feedback on overweight misperception in bully-victims. Both victims and bully-victims are at increased risk of weight misperception, posing further detrimental effects to their health and wellbeing. Copyright © 2017. Published by Elsevier Ltd.

In recent years, fatigue is common among adolescents. The aim of this study is to evaluate fatigue status and find related factors of fatigue among students ranged from 13-26 years from Wuhu, China. This is a case-control, cross-sectional observational study. The students from six middle schools (high school? 26 years old?) in Wuhu city were recruited, Self-Rating Fatigue Scale (SFS) was used to measure the fatigue status among students ranged from 13-26 years, and some demographic characteristics of students also was determined. A total of 726 students are included in our study. A significant difference was observed between fatigue status and grade, a balanced diet, the partial eclipse, picky for food, lack of sleep, excessive fatigue, drinking (P sleep, drinking; grade while a balanced diet is the protective factor of fatigue. Therefore, the school should pay more attention to the fatigue among students in middle school in China, and take some properly measures to reduce the fatigue.

Full Text Available Physical activity, nutrition, and sedentary behaviour combine to influence the risk of overweight among adolescents. This paper aims to identify psychosocial factors of different health behaviour patterns in adolescents and its association with overweight and weight control behaviours. The 3069 adolescents of both genders (average of 14.8 years old from the 2010 Portuguese survey of Health Behaviour School-Aged Children (HBSC answered the 2010 HBSC self-reported questionnaire. It used the cluster k-means (nonhierarchy method, qui-square, one-way ANOVA, and logistic regression. Three clusters with different behavioural patterns (physical activity, sedentary, and eating composed the results obtained. The sedentary group (34% had lower self-regulation, body satisfaction, health and wellness, family and classmates relationships, communication with the father than the other two groups. The active gamers (25% had a smaller BMI but used more unhealthy weight control strategies than the other two groups. The healthy group (41% was more motivated and more satisfied with school but was not different than the active gamers in most psychosocial variables. Differences were found between clusters for weight control behaviours and psychosocial variables. Different strategies for different patterns were necessary in order to promote obesity prevention and, simultaneously, target healthy lifestyle and wellbeing in adolescents.

Obesity is a serious problem of public health and affects all socio-economic groups, irrespective of age, sex or ethnicity. The aim of this study was to evaluate the association between periodontal condition and nutritional status of adolescents. This was a cross-sectional study using a probability cluster sampling, and the sample was defined by statistical criterion, consisting of 559 students aged 15-19 yr enrolled in public schools of adolescents of Campina Grande, PB, Brazil in 2012. Socioeconomic characteristics were analyzed, as well as self-reported general and oral health, anthropometric data and periodontal condition (CPI and OHI-S). Descriptive and analytical analysis from bivariate and multivariate Poisson regression analysis with 5% significance level was performed. Of the 559 adolescents, 18.6% were overweight and 98.4% had some form of periodontal changes such as: bleeding (34.3%), calculus (38.8%), shallow pocket (22.9%) and deep pocket (2.3%). There was association between presence of periodontal changes with obesity ( P periodontal changes and obesity status in adolescents was indicated.
Full Text Available Background: Studies evaluating the relationship between oral health status and obesity have provided conflicting data. Therefore, there is a great need to investigate and clarify the possible connection in a comprehensive sample. Aims: To assess the relationship of obesity and oral health status among children and adolescents aged 6 to 17 years-old. Study Design: Cross-sectional study. Methods: Data were obtained from 4,534 children and adolescents (2,018 boys and 2,516 girls. Questionnaires were sent home prior to examination; afterwards, anthropometric and dental data were collected from participants. Community Periodontal Index (CPI and number of decayed, missing, and filled teeth in the permanent dentition (DMFT, and deciduous dentition (dmft index were used to measure oral health status. Height, body weight, body mass index (BMI, waist circumference (WC, and body fat percentage were analyzed. Results: For DMFT scores, healthy (score=0 girls and boys had significantly higher BMI and WC values than unhealthy (score>1 girls and boys (p<0.05. Healthy girls had higher fat percentage values than unhealthy girls (p<0.05. In terms of CPI scores, healthy boys had lower BMI and WC values than unhealthy boys (p<0.05. According to multiple binary logistic regression results for model 1, BMI predicted DMFT scores in both genders but CPI scores only in boys. No beverage consumption predicted DMFT scores in boys, while milk consumption predicted DMFT scores in girls. No meal skipping predicted CPI scores in boys. For model 2, WC predicted DMFT scores in both genders and CPI scores only in boys. Milk consumption predicted DMFT scores only in girls. No meal skipping predicted CPI scores for both gender (p<0.05. According to DMFT, there were significant differences between the frequencies of the BMI groups (normal weight, overweight and obese at the age of 7 (girls only, 9, 10, and 16 (boys only years and overall (only girls (p<0.05.

Full Text Available Abstract Background Childhood obesity is a continuing problem in the UK and South Asian children represent a group that are particularly vulnerable to its health consequences. The relationship between body dissatisfaction and obesity is well documented in older children and adults, but is less clear in young children, particularly South Asians. A better understanding of this relationship in young South Asian children will inform the design and delivery of obesity intervention programmes. The aim of this study is to describe body image size perception and dissatisfaction, and their relationship to weight status in primary school aged UK South Asian children. Methods Objective measures of height and weight were undertaken on 574 predominantly South Asian children aged 5-7 (296 boys and 278 girls. BMI z-scores, and weight status (underweight, healthy weight, overweight or obese were calculated based on the UK 1990 BMI reference charts. Figure rating scales were used to assess perceived body image size (asking children to identify their perceived body size and dissatisfaction (difference between perceived current and ideal body size. The relationship between these and weight status were examined using multivariate analyses. Results Perceived body image size was positively associated with weight status (partial regression coefficient for overweight/obese vs. non-overweight/obese was 0.63 (95% CI 0.26-0.99 and for BMI z-score was 0.21 (95% CI 0.10-0.31, adjusted for sex, age and ethnicity. Body dissatisfaction was also associated with weight status, with overweight and obese children more likely to select thinner ideal body size than healthy weight children (adjusted partial regression coefficient for overweight/obese vs. non-overweight/obese was 1.47 (95% CI 0.99-1.96 and for BMI z-score was 0.54 (95% CI 0.40-0.67. Conclusions Awareness of body image size and increasing body dissatisfaction with higher weight status is established at a young age in

Adverse parental life-style habits are associated with offspring adiposity, but it is unclear how changes in these habits affect offspring adiposity. Thus, the aim of this study was to assess how parental change in body weight, smoking habits and levels of physical activity were associated with adiposity in their children. The study population consisted of 3 681 adolescents and their parents from the Nord-Trøndelag-Health-Study (HUNT). The parents participated in the two first waves of HUNT (HUNT-1:1984-86, HUNT-2:1995-97), where information on anthropometry, smoking habits and physical activity were obtained. The adolescents participated in the Youth-Part of HUNT-2. We used logistic regression to calculate odds-ratios (ORs) for adolescent offspring overweight according to parental change in body-weight, smoking habits and physical activity, adjusting for these factors in both parents, as well as for socioeconomic status and adolescent age and sex. Children of parents who changed weight from normal weight to overweight from HUNT-1 to HUNT-2 had higher OR for overweight in adolescence than children of parents who remained normal weight (mothers: 1.9 [95% CI: 1.4,2.5], fathers: 2.2 [95% CI: 1.5,3.0]). Children of mothers who reduced their weight from overweight to normal weight had no higher OR for overweight in adolescence than mothers who remained normal weight (OR: 1.0; 95% CI: 0.2, 4.7). Children of mothers who quit smoking (OR: 0.5; 95% CI: 0.3, 0.8) had lower OR for overweight in adolescence than children of mothers who persisted in smoking. Healthy changes in parental life-style during childhood are associated with lower occurrence of offspring overweight in adolescence.

To assess correlations between periodontal status, maternal age and adverse pregnancy outcomes, such as pre-term and low birth weight in a sample of pregnant women. Study population was represented by outpatient pregnant women, gestational age > 26 weeks. Medical history questionnaires were administered to all participants who underwent clinical evaluation; clinical obstetric outcome records were collected after delivery. A questionnaire was administered regarding personal information, socio-economic status, oral hygiene habits, and oral health conditions. A clinical oral examination was performed to collect Simplified Oral Hygiene Index (OHI-S) and Community Periodontal Index (CPI). Pregnancy outcome records included: delivery week, kind and causes of delivery, any relevant complications, and birth weight. Descriptive statistics were used to depict the data from the questionnaire while the relationship between delivery week, birth weight, maternal age and periodontal status was evaluated through multivariate tests of significance. 88 pregnant women were enrolled in the study. The results showed a statistically significant correlation (Pperiodontal disease and adverse pregnancy outcomes. No statistical correlation was found among pre-term and low birth weight, smoking, ethnicity and educational level of mothers. The results highlight the importance of including a routine oral and periodontal health examination in pregnant women older than 40 years of age. The correlation between periodontal status and adverse pregnancy outcomes in older mothers indicates the need for routine oral health examination and periodontal status assessment and care in pregnant women older than 40 years of age.

Objective Severe obesity is the fastest growing pediatric subgroup of excess weight levels. Psychological dysregulation (i.e., impairments in regulating cognitive, emotional, and/or behavioral processes) has been associated with obesity and poorer weight loss outcomes. The present study explored associations of dysregulation with weight-related variables among adolescent and young adult (AYA) females with severe obesity. Methods Fifty-four AYA females with severe obesity (MBMI=48.71 kg/m2; Mage=18.29, R=15–21 years; 59.3% White) completed self-report measures of psychological dysregulation and weight-related constructs including meal patterns, problematic eating behaviors, and body and weight dissatisfaction, as non-surgical comparison participants in a multi-site study of adolescent bariatric surgery outcomes. Pearson and bivariate correlations were conducted and stratified by age group to analyze associations between dysregulation subscales (affective, behavioral, cognitive) and weight-related variables. Results Breakfast was the most frequently skipped meal (consumed 3–4 times/week). Eating out was common (4–5 times/week) and mostly occurred at fast-food restaurants. Evening hyperphagia (61.11%) and eating in the absence of hunger (37.04%) were commonly endorsed, while unplanned eating (29.63%), a sense of loss of control over eating (22.22%), eating beyond satiety (22.22%), night eating (12.96%), and binge eating (11.11%) were less common. Almost half of the sample endorsed extreme weight dissatisfaction. Dysregulation was associated with most weight-related attitudes and behaviors of interest in young adults but select patterns emerged for adolescents. Conclusions Higher levels of psychological dysregulation are associated with greater BMI, problematic eating patterns and behaviors, and body dissatisfaction in AYA females with severe obesity. These findings have implications for developing novel intervention strategies for severe obesity in AYAs that may

Full Text Available The study investigated the relationship between body image dissatisfaction, nutritional status, and eating attitudes in adolescents from a small town of the interior of São Paulo State. A total of 278 adolescents (106 boys and 172 girls aged between 15 and 18 years had completed measures of body image dissatisfaction through the Figure Rating Scale and eating attitudes by the Eating Attitudes Test (EAT-26 and had their weight and height measured. Girls related more dissatisfaction and abnormal eating behavior than boys and, in both genders the abnormal eating attitudes tend to increase with increasing dissatisfaction. Moreover, dissatisfaction was higher between those individuals classified as overweight and obesity. These results demonstrated that body image dissatisfaction and inappropriate eating behaviors afflict boys and girls even from small cities in developing countries, highlighting the need to undertake epidemiological studies to early recognition of populations at risk of developing eating disorders.

Individuals who are overweight or obese report body image concerns and lower self-esteem. However, little is known about the mechanisms underpinning these associations. The objective of this study was to test body-related shame and guilt as mediators in the association between weight status and self-esteem. Young adult participants (n = 790) completed assessments of self-esteem and body-related guilt and shame, and weight status indicators were measured by trained technicians. Findings from multiple mediation analyses suggest that body-related shame mediates the relationship between weight status and self-esteem. If replicated in longitudinal studies, these findings suggest that reducing body-related emotions may have important implications for improving self-esteem in clinical weight management. © The Author(s) 2015.
