OBJECTIVE The present study uses longitudinal data to examine changes in body satisfaction among male and female adolescents from baseline to 5 years. METHODS A diverse sample of 2516 adolescents completed surveys in 1999 and 2004, reporting satisfaction with 10 body parts or attributes, height/weight, and other characteristics. Multivariable general linear modeling was used to estimate change in body satisfaction from Time 1 to Time 2, by age group, race, and change in body mass index (BMI) category. RESULTS Body satisfaction decreased over 5 years (mean satisfaction change=−0.79) in all groups except older adolescent females. Scores decreased significantly more among younger adolescents than older adolescents, among some racial/ethnic groups of males, and among those whose BMI increased. However, among males, change in body satisfaction depended on BMI category at baseline. CONCLUSIONS Different types of prevention programs addressing body image may be needed for males and females at different developmental stages and may need to address changes in BMI.

OBJECTIVE To describe adolescent involvement in preparing and shopping for food and examine if extent of involvement is related to diet quality. DESIGN Cross-sectional study design. Past week frequency of involvement in preparing and shopping for food was self-reported on the Project EAT (Eating Among Teens) survey. Dietary intake was assessed using the Youth/Adolescent Food Frequency Questionnaire. SUBJECTS/SETTING Middle school and high school students from Minneapolis/St Paul, MN, public schools. STATISTICAL ANALYSES PERFORMED Associations between involvement and sociodemographic characteristics were examined using cross tabulations. General linear modeling was used to compare dietary intakes of adolescents across different levels of involvement in preparing and shopping for food. RESULTS The majority of adolescents reported helping prepare dinner (68.6%) and nearly half reported shopping for groceries (49.8%) at least once during the past week. Greater involvement in these food tasks was related to sex (female), grade level (middle school), race (Asian American), socioeconomic status (low), family meal frequency (high), and weight status (overweight). Frequency of preparing food was related to lower intakes of fat (P<0.01) and higher intakes of fruits and vegetables, fiber, folate, and vitamin A. Preparing was related to lower intakes of carbonated beverages among female adolescents (P<0.01) and lower intakes of fried foods among male adolescents (P<0.01). In contrast, food shopping frequency was related to greater consumption of fried foods among female adolescents (P<0.01). CONCLUSIONS Adolescents should be encouraged to help with meal preparation and may benefit from interventions and programs that teach skills for cooking and making healthful purchasing decisions.

OBJECTIVE To determine if adolescents who report dieting and different weight-control behaviors are at increased or decreased risk for gains in body mass index, overweight status, binge eating, extreme weight-control behaviors, and eating disorders 5 years later. DESIGN Population-based 5-year longitudinal study. PARTICIPANTS Adolescents (N=2,516) from diverse ethnic and socioeconomic backgrounds who completed Project EAT (Eating Among Teens) surveys in 1999 (Time 1) and 2004 (Time 2). MAIN OUTCOME MEASURES Weight status, binge eating, extreme weight control, and self-reported eating disorder. STATISTICAL ANALYSIS Multiple linear and logistic regressions. RESULTS Adolescents using unhealthful weight-control behaviors at Time 1 increased their body mass index by about 1 unit more than adolescents not using any weight-control behaviors and were at approximately three times greater risk for being overweight at Time 2 (odds ratio [OR]=2.7 for girls; OR=3.2 for boys). Adolescents using unhealthful weight-control behaviors were also at increased risk for binge eating with loss of control (OR=6.4 for girls; OR=5.9 for boys) and for extreme weight-control behaviors such as self-induced vomiting and use of diet pills, laxatives, and diuretics (OR=2.5 for girls; OR=4.8 for boys) 5 years later, compared with adolescents not using any weight-control behaviors. CONCLUSIONS Dieting and unhealthful weight-control behaviors predict outcomes related to obesity and eating disorders 5 years later. A shift away from dieting and drastic weight-control measures toward the long-term implementation of healthful eating and physical activity behaviors is needed to prevent obesity and eating disorders in adolescents.

BACKGROUND This study examined 5-year longitudinal and secular trends in weight status and the use of healthy and unhealthy weight control behaviors in adolescents. METHODS Project EAT-II followed 2516 adolescents from Minnesota longitudinally from 1999 to 2004. The population included two cohorts allowing for the observation of transitions from early to middle adolescence (junior high school to high school) and from middle to late adolescence (high school to post-high school). RESULTS The prevalence of overweight (females: 28.7%; males: 28.0%) was high in early adolescence and remained high throughout adolescence. In females, between early and middle adolescence, there were steep longitudinal increases in the use of unhealthy weight control behaviors (48.6% to 58.8%, P = 0.001) and extreme weight control behaviors (9.4% to 17.9%, P < 0.001), and between middle and late adolescence, extreme weight control behaviors increased from 14.5% to 23.9% (P < 0.001). In males, extreme weight control behaviors doubled from middle to late adolescence (3.4% to 6.3%, P = 0.023). Use of diet pills doubled from 7.5% to 14.2% from 1999 to 2004 (P = 0.004) in high school females. One fifth (19.9%) of females in late adolescence reported taking diet pills. CONCLUSIONS Overweight status and unhealthy weight control behaviors in adolescents are major public health concerns that warrant interventions addressing both problems.

PURPOSE To examine correlates of dieting behavior in overweight and non-overweight youth. METHODS Data came from Project EAT (Eating Among Teens), a study of eating and weight-related attitudes, behaviors, and psychosocial variables among 4746 adolescents in public schools. Logistic regression was used to compare dieters and non-dieters, and to examine interactions of dieting and overweight status. RESULTS Approximately one third (31.8%) of the sample was overweight. Dieting in the previous year was reported by 55.2% of girls and 25.9% of boys. Dieting was associated with similarly elevated rates of extreme weight control behaviors, body dissatisfaction, and depression in both the non-overweight and overweight groups for both boys and girls. Girls reporting dieting behavior in both the non-overweight and overweight groups had similarly elevated risk for cigarette use, alcohol use, and marijuana use. CONCLUSIONS The negative correlates of dieting are similarly common among teens of varying weight status. These data suggest that dieting may not be a preferred method of weight management, even for overweight adolescents. Regardless of weight status, dieting may be a marker for other unhealthy behaviors and depressed mood in adolescents.

OBJECTIVE The purpose of this study was to explore the relationship between maternal and adolescent weight-related behaviors and concerns in a population-based sample. METHODS Participants were 810 adolescents (n=429 girls and n=381 boys) and their mothers/guardians. Adolescents were part of the Project EAT (Eating Among Teens) study, which was a comprehensive study of eating patterns and weight concerns among adolescents in Minnesota. Outcome variables included child's body dissatisfaction, weight concerns, dieting, and use of healthy and unhealthy weight control behaviors. RESULTS Adolescents reported lower rates of maternal dieting than mothers. Maternal self-report of dieting was not significantly associated with children's weight-related concerns. Children's perceptions of their mothers' behaviors were significantly related to their level of weight concerns and use of weight control behaviors. CONCLUSION Adolescents' perceptions of maternal behavior affect their weight-related concerns and behaviors. This suggests that mothers who choose to diet should model healthy choices in the areas of nutrition and physical activity.

OBJECTIVE To assess whether weight-related teasing predicts the development of binge eating, unhealthy weight control behaviors, and frequent dieting among male and female adolescents. METHODS A prospective study was conducted with an ethnically and socioeconomically diverse sample of 2516 adolescents who completed surveys at both time 1 (1998-1999) and time 2 (2003-2004) of the Project EAT (Eating Among Teens) study. RESULTS In 1998-1999, approximately one fourth of participants reported being teased about their weight at least a few times a year. After adjustment for age, race/ethnicity, socioeconomic status (SES), and BMI, boys who were teased about their weight were more likely than their peers to initiate binge eating with loss of control and unhealthy weight control behaviors 5 years later. The predicted prevalence for incident binge eating behaviors with loss of control among boys who were teased was 4.1% as compared with 1.4% for those who were not teased, after adjustment for age, race/ethnicity, SES, and BMI. For unhealthy weight control behaviors at time 2, the predicted prevalence was 27.5% among boys who were teased and 19.3% for boys who were not teased, after adjustment for age, race/ethnicity, SES, and BMI. Girls who were teased were more likely than their peers to become frequent dieters. The predicted prevalence for incident frequent dieting among girls who were teased was 18.2% as compared with 11.0% for those who were not teased, after adjustment for age, race/ethnicity, SES, and BMI. CONCLUSIONS Weight teasing in adolescence predicts disordered eating behaviors at 5-year follow-up. The patterns of these associations differ by gender. Reducing teasing through educational interventions and policies may reduce the level of disordered eating behaviors among youths.

PURPOSE To determine if weight-teasing predicts subsequent low self-esteem, poor body image, and depressive symptoms; and to examine two mechanisms through which early teasing may influence later emotional health. METHODS A racially and socio-economically diverse sample of 2516 adolescents completed surveys for both Wave 1 (1998–99) and Wave 2 (2003–04) of the Project EAT study. Approximately one third of these were early adolescents who transitioned into middle adolescence, and two thirds were middle adolescents who transitioned into young adulthood. Multiple linear regression analysis was conducted in three stages to test Model A: the total effect of Time 1 teasing on Time 2 emotional health; Model B: Model A, mediated by Time 2 teasing and body mass index (BMI); and Model C: Model B, also mediated by Time 1 emotional health. RESULTS Approximately one third of males and slightly under half of females reported that they had been teased about their weight at Time 1. Time 1 teasing predicted lower self-esteem, lower body image, and higher depressive symptoms at Time 2 for males and females in the older and younger age groups. This relationship was fully mediated, however, by Time 2 teasing and BMI, and by Time 1 emotional health. Adjusted R2 statistics for the final models ranged from .11 to .36. CONCLUSIONS Weight-teasing in adolescence affects emotional well-being at 5-year follow-up, and appears to function through two mechanisms. Reducing early teasing and its concurrent damages to emotional health may prevent longer-term emotional health consequences.

PURPOSE The purpose of this study was 2-fold: (1) to determine the prevalence of high body satisfaction in a multi-ethnic, urban population of adolescent females, and (2) to examine the demographic, socioenvironmental, personal, and behavioral factors associated with high body satisfaction among adolescent girls. METHODS The study population included 2,357 female middle and high school students who completed surveys in 1998–1999. High body satisfaction and its association with a range of socioenvironmental, personal, and behavioral factors were assessed. Associations were examined through comparisons of means (unadjusted and adjusted for grade level, race, socioeconomic status, and body mass index [BMI]) for continuous variables, and percentages and odds ratios for dichotomized variables. RESULTS Over a quarter (26.7%) of adolescent girls reported high body satisfaction. High body satisfaction was most common among African-American (40.1%) and underweight girls (39.0%). In adjusted analyses, girls with high body satisfaction were more likely to report parental and peer attitudes that encouraged healthy eating and exercising to be fit (p < .001) versus dieting, and less likely to report personal weight-related concerns and behaviors (p < .001). CONCLUSIONS The immediate subculture in which adolescent girls exist may play an important role in fostering high body satisfaction. Parents and health care providers often struggle with how to address the topic of weight management in teens without causing further injury to body image. Findings from the present study suggest the importance of providing a social environment that focuses on health and fitness, rather than on weight control, to increase adolescent girls’ likelihood of being satisfied with their bodies.

OBJECTIVE This study examines parental report of household food availability, parent dietary intake and associations with adolescent intakes of fruits, vegetables and dairy foods. DESIGN Cross-sectional study. Adolescents completed the Project EAT survey and the Youth Adolescent Food Frequency Questionnaire at school. Parents of adolescents were interviewed by telephone about the home food environment, eating habits and weight-related behaviours. General linear modelling was used to compare dietary intakes of adolescents across different levels of household food availability and parental intakes. SUBJECTS/SETTING The study sample included 902 adolescents and their parent or guardian. RESULTS Many parents were not consuming the minimum number of daily recommended fruit (44.5%), vegetable (69.9%) or dairy (46.9%) servings. While most parents reported that fruits and vegetables were available at home (90.3%) and vegetables were usually served at dinner (87.0%), fewer parents reported milk was served at meals (66.6%). Soft drinks were usually available at home (56.8%). Among girls, household availability was positively associated with fruit and vegetable intake (ttrend=2.70, P<0.01) and soft drink availability was inversely associated with dairy intake (ttrend=2.08, P=0.04). Among boys, serving milk at meals was positively associated with dairy intake (ttrend=3.65, P<0.01). Parental intakes were positively associated with dairy intake for boys (ttrend=2.04, P=0.04), and with dairy (ttrend=2.43, P=0.01), vegetable (ttrend=3.72, P<0.01) and fruit (ttrend=3.17, P<0.01) intakes for girls. CONCLUSIONS/APPLICATIONS Interventions designed to help adolescents improve consumption of fruits, vegetables and dairy foods may be enhanced by including a parental component aimed at increasing household availability and parents' intake of healthful food choices.

Dieting is common among adolescent girls and may place them at risk of using unhealthy weight-control behaviors (UWCBs), such as self-induced vomiting, laxatives, diet pills, or fasting. Research has suggested that social factors, including friends and broader cultural norms, may be associated with UWCBs. The present study examines the relationship between the school-wide prevalence of current weight loss efforts among adolescent girls, friends’ dieting behavior, and UWCBs, and investigates differences in these associations across weight categories. Survey data were collected in 31 middle and high schools in ethnically and socio-economically diverse communities in Minnesota, USA. The response rate was 81.5%. Rates of UWCBs were compared across the spectrum of prevalence of trying to lose weight and friends’ involvement with dieting, using χ2 analysis and multivariate logistic regression, controlling for demographic factors and clustering by school. Girls with higher body mass index (BMI) were more likely to engage in UWCBs than those of lower BMI. Multivariate models indicated that friends’ dieting behavior was significantly associated with UWCBs for average weight girls (OR=1.57, CI=1.40–1.77) and moderately overweight girls (OR=1.47, CI=1.19–1.82). The school-wide prevalence of trying to lose weight was significantly, albeit modestly, related to UWCBs for average weight girls (15th–85th percentile; OR=1.17, CI=1.01–1.36), and marginally associated for modestly overweight girls (85th–95th percentile; OR=1.21, CI=.97–1.50), even after controlling for friends’ dieting behaviors. The social influences examined here were not associated with UWCBs among underweight (<15th percentile) or overweight (>95th percentile) girls. Findings suggest that social norms, particularly from within one's peer group, but also at the larger school level may influence UWCBs, particularly for average weight girls. Implications for school-based interventions to reduce UWCBs are discussed.

Individuals with high body mass index (BMI), negative body image, and unhealthy weight control behaviors may be more likely to engage in high-risk sexual behaviors than others. Researchers have not fully investigated these relationships in a sample of college students. The authors collected data regarding several weight-related issues and high-risk sexual behaviors (response rate = 39%) from 1,168 college students. Over half reported at least 1 high-risk sexual behavior. After the authors controlled for several demographic characteristics, they found that higher BMIs were associated with increased odds of having a casual sexual partner (odds ratio [OR] = 2.70) and being intoxicated at last intercourse (OR = 2.25). Among women, unhealthy weight control behaviors were associated with having a casual partner (OR = 2.12), using no or unreliable contraception (OR = 1.98), and being intoxicated at last intercourse (OR = 2.31). Weight-related issues were not associated with sexual behaviors among college men. Th...

Although many children with Attention-Deficit/Hyperactivity Disorer (ADHD) are described as "clumsy," there is relatively little research on problems in motor development in this population. We used a survey method to assess retrospectively developmental histories of 25 children with ADHD and 27 control children (ages 8-15 years). Children with ADHD reportedly had more difficulty than control children with both learning and performing a variety of motor skills, e.g., tying shoes, printing letters, playing sports. In contrast, parents reported few problems in their children's language development. Severity of motor problems was related to performance on specific IQ indices and reading and spelling tests. Given previous research on adverse consequences of clumsiness in children with attention deficits, results of this preliminary study indicate that further research on motor development can shed light on the developmental psychopathology of ADHD.

<h3>Background</h3><p>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.</p><h3>Objective</h3><p>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.</p><h3>Design</h3><p>Secondary analysis of survey and anthropometric data.</p><h3>Setting</h3><p>Ethnically and socioeconomically diverse communities in the urban and suburban school districts of the Minneapolis/St Paul metropolitan area.</p><h3>Participants</h3><p>A school-based sample of 4746 adolescents in grades 7 to 12 at 31 public middle schools and high schools.</p><h3>Main Outcome Measures</h3><p>Weight-based teasing from peers or family members, body satisfaction, self-esteem, depressive symptoms, and suicidal ideation and suicide attempts.</p><h3>Results</h3><p>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.</p><h3>Conclusions</h3><p>Physicians and other health care providers should recognize the importance of weight-based teasing for young patients.

OBJECTIVE To assess the prevalence of overeating among adolescents and to examine associations between overeating and sociodemographic characteristics, weight status, dieting behaviors, body satisfaction, depressive mood, self-esteem, and suicide. METHOD A school-based sample of 4746 boys and girls in public middle and high schools in Minnesota completed the Project EAT (Eating Among Teens) survey and anthropometric measurements of height and weight. RESULTS Overall, 17.3% of girls and 7.8% of boys reported objective overeating in the past year. Youths who engaged in overeating were more likely to be overweight or obese, to have dieted in the past year, to be trying to lose weight currently, and to report that weight and shape are very important to their overall feelings about self. Youths who met criteria for binge eating syndrome (high frequency of objective overeating with loss of control and distress regarding the binge eating) scored significantly lower on measures of body satisfaction and self-esteem and higher on a measure of depressive mood than those who reported either subclinical or no binge eating. Overeating was associated with suicide risk; more than one fourth of girls (28.6%) and boys (27.8%) who met criteria for binge eating syndrome reported that they had attempted suicide. CONCLUSIONS Overeating among adolescents is associated with a number of adverse behaviors and negative psychological experiences. As the current study is cross-sectional, it is not possible to ascertain cause and effect. Future research should seek to identify whether objective overeating is an early warning sign of additional psychological distress or is a potential consequence of compromised psychological health. Clinical implications are discussed.
