Economic costs associated with unhealthy weight control behaviors among Australian adolescents.

OBJECTIVE: This study explored the relationship between unhealthy weight control behaviors (UWCBs) and their associated economic costs among adolescents using the 2014-2018 Longitudinal Study of Australian Children (LSAC). METHODS: LSAC data in Wave 6 (n = 3538 adolescents aged 14-15 years), Wave 7 n = 3089 adolescents aged 16-17 years), and Wave 8 (n = 3037 adolescents aged 18-19 years) were derived from a representative sample of Australian adolescents. UWCBs were measured using the self-reported Branched Eating Disorder Test questionnaire. UWCBs were sub-classified into having fasting behaviors, using weight loss supplements or purging behaviors. Economic costs include healthcare and productivity costs to caregivers. Healthcare costs were measured using data from the Medicare and Pharmaceutical Benefits, which includes both medical and pharmaceutical costs. Productivity losses were measured using caregivers' lost leisure time due to UWCBs among adolescents. RESULTS: The mixed effect model identified statistically significant higher economic costs (mean difference = $453, 95% CIs $154, $752), higher health care costs (mean difference = $399, 95% CIs $102, $695), and higher productivity costs (mean difference = $59, 95% CIs $29, $90) for adolescents with UWCBs compared to their peers with no UWCBs. Subgroup analysis revealed that higher costs were associated with fasting and purging behaviors. DISCUSSION: UWCBs were associated with increased economic costs during adolescence. Our finding suggests there should be a policy focus on tackling UWCBs to reduce the economic burden on the healthcare system and society. PUBLIC SIGNIFICANCE: The study contributes to existing knowledge by investigating the direct healthcare costs and productivity losses associated with unhealthy weight control behaviors in Australian adolescents (14-18 years old) using a dataset that follows Australian adolescents over time. We found that engaging in unhealthy weight control behaviors such as fasting, using weight loss supplements, and purging was linked to higher costs among adolescents, suggesting policies should focus on addressing these behaviors.

Population-level policy recommendations for the prevention of disordered weight control behaviors: A scoping review.

OBJECTIVE: The aim of this scoping review was to identify recommendations and gaps in knowledge surrounding the prevention of disordered weight control behaviors (DWCBs) through policy. METHOD: A search was conducted in several databases to identify English language articles that described an active policy, recommendation, guideline, or educational curriculum that could be implemented by governments or regulatory bodies to prevent DWCBs or related constructs (e.g., weight stigma, body dissatisfaction). Two researchers independently screened articles with oversight from a third researcher. Data were extracted from the final sample (n = 65) and analyzed qualitatively across all articles and within the domains of education, public policy, public health, industry regulation, and media. RESULTS: Only a single empirical evaluation of an implemented policy to reduce DWCBs was identified. Over one-third of articles proposed recommendations relating to industry regulation and media (n = 24, 36.9%), followed by education (n = 21, 32.3%), public policy (n = 19, 29.2%), and public health (n = 10, 15.4%). Recommendations included school-based changes to curricula, staff training, and anti-bullying policies; legislation to ban weight discrimination; policies informed by strategic science; collaboration with researchers from other fields; de-emphasizing weight in health communications; diversifying body sizes and limiting modified images in media; and restricting the sale of weight-loss supplements. DISCUSSION: The findings of this review highlight gaps in empirically evaluated policies to reduce DWCBs but also promising policy recommendations across several domains. Although some policy recommendations were supported by empirical evidence, others were primarily based on experts' knowledge, highlighting the need for greater research on population-level DWCBs prevention through policy. PUBLIC SIGNIFICANCE: Our scoping review of the evidence on policies for the prevention of disordered weight control behaviors identified several recommendations across the domains of education, public policy, public health, and industry regulation and media. Although few empirical investigations of implemented policies have been conducted, expert recommendations for policies to prevent disordered weight control behaviors among populations are plentiful and warrant future consideration by researchers and policymakers alike.

OBJETIVO: El objetivo de esta revisión sistemática exploratoria fue identificar recomendaciones y lagunas en el conocimiento sobre la prevención de comportamientos disfuncionales de control de peso (DWCB) a través de políticas. MÉTODO: Se realizó una búsqueda en varias bases de datos para identificar artículos en ingel resumenlés que describieran una política activa, recomendación, directriz o currículo educativo que pudieran implementar los gobiernos u organismos reguladores para prevenir DWCB o constructos relacionados (por ejemplo, estigma de peso, insatisfacción corporal). Dos investigadores examinaron de forma independiente los artículos con la supervisión de un tercer investigador. Los datos se extrajeron de la muestra final (n = 65) y se analizaron cualitativamente en todos los artículos y dentro de los dominios de educación, políticas públicas, salud pública, regulación de la industria y medios de comunicación. RESULTADOS: Solo se identificó una evaluación empírica única de una política implementada para reducir los DWCB. Más de un tercio de los artículos propusieron recomendaciones relacionadas con la regulación de la industria y los medios de comunicación (n = 24, 36.9%), seguido de educación (n = 21, 32.3%), políticas públicas (n = 19, 29.2%) y salud pública (n = 10, 15.4%). Las recomendaciones incluyeron cambios en los planes de estudio, capacitación del personal y políticas contra el acoso (bullying); legislación para prohibir la discriminación por peso; políticas basadas en la ciencia estratégica; colaboración con investigadores de otros campos; restar importancia al peso en las comunicaciones sanitarias; diversificar los tamaños corporales y limitar las imágenes modificadas en los medios; y restringir la venta de suplementos para bajar de peso. DISCUSIÓN: Los hallazgos de esta revisión destacan las brechas en las políticas evaluadas empíricamente para reducir los DWCB, pero también las recomendaciones de políticas prometedoras en varios dominios. Aunque algunas recomendaciones de políticas estaban respaldadas por evidencia empírica, otras se basaban principalmente en el conocimiento de expertos, destacando la necesidad de una mayor investigación sobre la prevención de DWCB a nivel poblacional a través de políticas.

Association between dating app use and unhealthy weight control behaviors and muscle enhancing behaviors in sexual minority men: a cross-sectional study.

BACKGROUND: Body image concerns are prevalent and are viewed as risk factors for engaging in unhealthy weight control behaviors (UWCBs), such as purging, fasting, and the misuse of laxatives and diet pills. Studies have also linked UWCBs to the development of eating disorders. In the United States (U.S.), sexual minority men (e.g., bisexual, gay, and men who have sex with men) are prone to UWCBs often as a result of societal pressures to achieve certain standards of appearance - of which are often perpetuated through various media platforms. A growing number of studies have explored the possible role mobile dating applications ("dating apps") play in contributing to UWCBs. To our knowledge, such studies have not explored this possible relationship between dating apps and UWCBs in sexual minority men (SMM). To fill this gap in the scientific literature, the present study assessed the association between dating app use and UWCBs and muscle enhancing behaviors among a sample of adult SMM in the U.S. METHOD: 549 SMM participated in an anonymous survey from Qualtrics Survey Panels. UWCBs and muscle enhancing behaviors were assessed through items adapted from national surveys. Body image dissatisfaction was assessed using the Male Body Attitudes Scales. Participants also reported their history of dating app use. We performed descriptive statistics, chi-square tests, and student's t-tests. Multivariable logistic regression models assessed the relationship between dating app use and UWCBs and muscle enhancing behaviors. RESULTS: Dating app users had significantly higher body image dissatisfaction scores than non-users. Dating app users also demonstrated significantly elevated odds of engaging in four UWCBs and muscle enhancing behaviors: laxatives, diet pills, muscle-building supplements, and protein powders. CONCLUSIONS: This is one of the first studies to assess dating app use and its association with UWCBs and muscle enhancing behaviors in SMM. Increased surveillance and detection for such behaviors among SMM, particularly those using dating apps, are needed.

Factors associated with the adoption of extreme weight control behavior by non-obese adolescents: a secondary analysis.

BACKGROUND: Misperceptions about obesity is common among adolescents. Adolescents who overestimate their body size tend to indulge in extreme weight control behaviors. However, little is known about the factors involved in the adoption of extreme weight control behavior (EWCB) by non-obese adolescents who are mistaken for being overweight. This study identified factors associated with unhealthy behaviors among normal/underweight high school students who overestimate their body image and attempt to lose weight. DESIGN: A secondary analysis of nationally representative data from the Korea Youth Risk Behavior Survey focused on adolescents who attended vocational and academically oriented high schools. METHODS: The analysis included data from 4,286 non-obese respondents (15-18 years) who overestimated their body weight. Of them, 2,887 were girls (66.5%), while 1,399 were boys (33.5%). Multiple logistic regression was used to investigate risk factors for EWCB by sex. A statistical analysis reflecting strata, clusters, and weights of the complex sampling design was adopted. RESULTS: Of the respondents, 674 (23.3%) girls and 162 (11.5%) boys reported EWCB. For both sexes, vocational high school attendance and depression were significantly influenced by EWCB. EWCB was linked to perceived stress in girls and living in a big city in boys. CONCLUSIONS: The findings suggest the importance of providing quality health education, including that for non-obese adolescents, in school obesity prevention programs along with the expansion of tailored intervention programs based on sex, following a consideration of the characteristics of high schools as well as individuals.

Unhealthy weight control behaviors and related factors by gender and weight status: Results from a nationally representative sample of Korean adolescents.

Given the serious consequences of unhealthy weight control behaviors (UWCB) among adolescents, identifying factors contributing to it in this population is crucial. Although gender differences have been reported as UWCB-related factors, studies on weight status remain limited. Hence, using a nationally representative sample, we investigated the differences in UWCB-related factors by gender and weight status. Most sociodemographic, health-related behavior, psychosocial, and school factors were remarkably correlated with UWCB in the normal-weight female group; however, they demonstrated most inconsistent correlations in the overweight female group. Overall, this study suggests that UWCB-preventing interventions in adolescents should be customized by gender and weight status.

Association between weight control behaviors and diet quality among Brazilian adolescents and young adults: Health Survey of São Paulo with Focus on Nutrition, 2015.

PURPOSE: Little is known about how behaviors to control weight are associated with diet quality among youth from low- and middle-income countries. The aim of this study was to examine associations between efforts to control weight (ECW) and diet quality among Brazilian adolescents and young adults. METHODS: Data from 731 participants (17.89 ± 4.92 years, 51.1% female) of the 2015 Health Survey of São Paulo were used for this cross-sectional study. Dietary intake was assessed using a 24 h dietary recall and diet quality was calculated using the Brazilian Healthy Eating Index-Revised (BHEI-R). Participants reported their ECW, weight satisfaction, and socio-demographics. Descriptive statistics and linear regressions were calculated to investigate associations between ECW and diet quality. RESULTS: Approximately 47.7% of participants were dissatisfied with their current weight, and 41.0% reported ECW. Reported strategies to control weight included increased physical activity, taking care of what they eat, and dieting (8.2, 3.1, and 2.5%, respectively). After adjusting for age, sex, race/ethnicity, and body mass index, reporting at least one ECW (ß = 0.08; 95% CI 0.02, 0.13), taking care of what to eat (ß = 0.15; 0.08, 0.22) and being satisfied with their weight (0.08; 0.02, 0.13) were all associated with a higher overall BHEI-R score. CONCLUSION: Overall diet quality score showed a small increase in participants reporting ECW. Further studies should be conducted to provide strategies used by adolescents from low- and middle-income countries to control their weight. Thus, developing public health policies, and behavioral-change strategies. LEVEL V: Cross-sectional descriptive study.

Body Weight Perception and Health-Related Behaviors Among U.S. Adolescents: Mediating Effects of Body Weight Control Behaviors.

This study examined mediating effects of body weight control behaviors in the relationship between body weight perception and health-related behaviors among 11,458 U.S. adolescents from the 2010 National Youth Physical Activity and Nutrition Survey. Parallel multiple mediation analysis was performed for the secondary data analysis. Nearly one third of adolescents (32.5%) had overweight or obesity; one quarter (25.0%) perceived themselves as slightly overweight and 5.1% thought they were very overweight. More girls (58.6%) had tried to lose weight than boys (32.3%), while boys were more physically active than girls. Healthy and unhealthy weight control behaviors significantly mediated the relationship between adolescents' body weight perception and health-related behaviors (physical activity and screen time). Teachers and parents should help adolescents have accurate weight perception and utilize reliable and healthy weight control strategies. Future studies should consider the intercorrelated relationships among adolescents' perceptions and behaviors regarding weight to provide successful weight control intervention programs.

Disordered eating behaviors and sexual objectification during New York fashion week: Implementation of industry policies and legislation.

OBJECTIVE: The working conditions of professional fashion models may place them at risk for negative outcomes including disordered eating. New policies in the United States and France, including providing private changing areas and requiring medical certificates, have been implemented to protect models from pressures to be extremely thin and sexual harassment. This study evaluated the implementation of the new policies during the week of New York Fashion Week, February 2018 (NYFW Fall'18). METHOD: A sample of 76 fashion models (87% female) aged over 18 years who had participated in NYFW Fall'18 completed an online survey, reporting on behaviors and experiences occurring during NYFW Fall'18. RESULTS: A large proportion of respondents reported unhealthy weight control behaviors, including skipping meals (54%), intravenous drips (39%), and self-induced vomiting (25%). Fewer than half reported being always or sometimes provided with a private changing area, with 45% reporting experiencing lack of privacy when changing. A subset (n = 15) had obtained a health certificate for events in Paris. Most health providers had assessed weight, but few assessed eating and exercise behaviors. DISCUSSION: Policy interventions to improve health and safety of models are not yet achieving intended goals and require continued monitoring.

Unhealthy weight control behaviors among a sample of U.S. journalists.

OBJECTIVE: Research on body image and weight control behaviors among journalists is limited. To fill this knowledge gap, we conducted a cross-sectional study to assess the experiences of unhealthy weight control behaviors (UWCBs), binge eating, and appearance-related pressures among a sample of journalists in the United States (U.S.). METHOD: We administered an online survey to journalists assessing their roles in the news industry, engagement in UWCBs (e.g., vomiting, laxative use, dieting, fasting) and binge eating. Odds ratios of the outcomes were estimated using a series of multivariate logistic regression models. RESULTS: Over 68%, 19%, and 30% of participants reported they went on a diet, fasted for weight control, and binge ate, respectively. Our results suggest on-air journalists demonstrated higher odds of dieting compared to their counterparts who do not work in front of the camera. Furthermore, some journalists reported being subjected to appearance-related pressures in the industry. DISCUSSION: Our results provide a glimpse of weight control behaviors, binge eating, and appearance-related pressures among workers in the U.S. journalism industry. Given the concerning prevalence of purging and binge eating in our sample, future studies should assess whether journalists represent an occupation group that is at high risk of developing eating disorders.

The role of peer victimization, sexual identity, and gender on unhealthy weight control behaviors in a representative sample of Texas youth.

OBJECTIVE: The aim of the study is to examine the association between victimization and unhealthy weight control behaviors (UWCB), accounting for other key correlates of UWCB while considering the moderating role of sexual identity and gender. METHOD: This study used data from the 2017 Texas Youth Risk Behavior Survey (YRBS), a representative sample of students in grades 9-12 in the U.S. state of Texas, including 2,067 students (1,754 heterosexuals and 313 sexual minorities). We used survey-weighted logistic regression to examine the association of sexual identity, gender, and victimization (dating violence, cyberbullying, and school bullying) with UWCB, after adjusting for demographic information and indicators of weight, physical activity, and support from adults. RESULTS: Unhealthy weight control behaviors were associated with older age, being obese, lack of support from adults, low physical activity, and cyberbullying. A significant three-way interaction between gender, sexual identity and bullying showed that bullying was associated with high levels of UWCB among sexual minority males. DISCUSSION: Our study highlights the role of victimization in health behaviors for stigmatized groups, and the importance of school efforts to implement an equitable and safe learning environment for all students.

Relationship between unhealthy weight control behaviors and substance use patterns among Korean adolescents: results from the 2017 national youth risk behavior survey.

OBJECTIVE: Unhealthy weight control behaviors (UWCBs) can lead to numerous health problems. Adolescents who engage in UWCB are more likely to abuse substances than other adolescents. However, few studies have examined the relationship between UWCB and substance use, despite the fact that their co-occurrence can result in greater morbidity and mortality. The aim of this study was to examine the association between UWCB and substance use patterns among Korean adolescents using nationally representative data. STUDY DESIGN: This study involved an analysis of statistical data collected from 27,284 adolescent participants (13-18 years old) in the 2017 Korean Youth Risk Behavior Web-based Survey. METHODS: The Chi-squared test and multiple logistic regression analysis were performed to demonstrate the association between substance use patterns (energy drink intake, alcohol use, cigarette smoking, electronic cigarette use, and drug use) and UWCB (one-food diets, fasting, diet pill use, and purging). All statistical analyses were performed to reflect complex sampling weights. RESULTS: More female than male adolescents reported to be engaged in any of the following UWCBs: one-food diets (female: 9.6%, male: 4.8%), fasting (female: 11.6%, male: 7.4%), diet pill use (female: 2.9%, male: 1.5%), and purging (female: 4.1%, male: 2.2%). The prevalence of all UWCBs tended to increase as energy drink intake (P < 0.001), cigarette smoking (P < 0.001), and electronic cigarette use (P < 0.001) increased. CONCLUSIONS: Health professionals who work with adolescents need to be aware of the importance of screening for UWCB, including one-food diets, fasting, diet pill use, and purging, especially as a co-occurrence with substance use.

Prevalence and Correlates of Disordered Eating Behaviors Among Young Adults with Overweight or Obesity.

BACKGROUND: Clinical and community samples indicate that eating disorders (EDs) and disordered eating behaviors (DEBs) may co-occur among adolescents and young adults at a weight status classified as overweight or obese. OBJECTIVE: To determine the prevalence of EDs and DEBs among young adults at a weight status classified as overweight or obese using a nationally representative sample and to characterize differences in prevalence by sex, race/ethnicity, sexual orientation, and socioeconomic status. DESIGN: Cross-sectional nationally representative data collected from Wave III of the National Longitudinal Study of Adolescent to Adult Health (Add Health). PARTICIPANTS: Young adults ages 18-24 years old. MAIN MEASURES: ED diagnosis and DEBs (self-reported binge eating or unhealthy weight control behaviors including vomiting, fasting/skipping meals, or laxative/diuretic use to lose weight). Covariates: age, sex, race/ethnicity, sexual orientation, weight status, and education. KEY RESULTS: Of the 14,322 young adults in the sample, 48.6% were at a weight status classified as overweight or obese. Compared to young adults at a weight status classified as underweight or normal weight, those at a weight status classified as overweight or obese reported a higher rate of DEBs (29.3 vs 15.8% in females, 15.4 vs 7.5% in males). Logistic regression analyses demonstrated that odds of engaging in DEBs were 2.32 (95% confidence interval 2.05-2.61) times higher for females compared to males; 1.66 (1.23-2.24) times higher for Asian/Pacific Islander compared to White; 1.62 (1.16-2.26) times higher for homosexual or bisexual compared to heterosexual; 1.26 (1.09-1.44) times higher for high school or less versus more than high school education; and 2.45 (2.16-2.79) times higher for obesity compared to normal weight, adjusting for all covariates. CONCLUSIONS: The high prevalence of DEBs particularly in young adults at a weight status classified as overweight or obese underscores the need for screening, referrals, and tailored interventions for DEBs in this population.

Unhealthy weight control behaviors mediate the association between weight status and weight-specific health-related quality of life in treatment-seeking youth who are obese.

PURPOSE: 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). METHOD: 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. RESULTS: 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. DISCUSSION: 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.

Eating disorder pathology in elite adolescent athletes.

OBJECTIVE: We aimed to investigate eating disorder pathology in German elite adolescent athletes. Evidence suggests that eating disorder pathology is more common in adult elite sports, especially in female athletes and in sports emphasizing leanness. There is a scarcity of studies in elite adolescent athletes who are in a vulnerable developmental stage and are affected by general as well as sport-specific risk factors. METHOD: Our data was derived from the German Young Olympic Athletes' Lifestyle and Health Management Study (GOAL) which conducted a survey in 1138 elite adolescent athletes. In this sample, we assessed body weight, weight control behavior, body acceptance and screened overall for core symptoms of eating disorders, depression and anxiety. We performed a tree analysis to identify high risk groups for eating disorder pathology. RESULTS: High risk groups comprised (a) athletes competing in weight dependent sports, and among athletes competing in disciplines other than weight dependent sports (b) athletes who are high on negative affectivity, (c) female athletes and (d) male athletes competing in endurance, technical or power sports. Athletes competing in weight dependent disciplines reported wide spread use of compensatory behaviors to influence body weight. Athletes reporting eating disorder pathology showed higher levels of depression and anxiety than athletes without eating disorder pathology. DISCUSSION: Increased psychosocial burden in athletes with eating disorder pathology suggests that eating disorder symptoms should not be accepted as an unproblematic and functional part of elite sports. The prevention and management of eating disorder pathology is especially important in weight dependent sports. © 2016 Wiley Periodicals, Inc. (Int J Eat Disord 2016; 49:553-562).

Risk Factors for Disordered Eating in Overweight Adolescents and Young Adults.

OBJECTIVE: To investigate risk factors for disordered eating among overweight youth, a subset of the population particularly at risk for such behaviors. METHODS: A population-based sample of overweight youth (n = 553) self-reported their disordered eating (binge eating, extreme weight control behaviors), depression-related symptoms, body dissatisfaction, and weight-related teasing at 5-year intervals spanning early/middle adolescence (Time 1; T1), middle adolescence/early young adulthood (Time 2; T2), and early/middle young adulthood (Time 3; T3). RESULTS: Using logistic regression, we found that T2 depression-related symptoms (p = .02) and body dissatisfaction (p = .01), and increases in body dissatisfaction from T1 to T2 (p = .03), predicted disordered eating incidence at T3. CONCLUSIONS: Depression-related symptoms and body dissatisfaction appear to be important risk factors for disordered eating among overweight youth. Eating disorder prevention programs should address these factors along with behaviors maintaining or exacerbating excess weight status.

The role of overweight perception and depressive symptoms in child and adolescent unhealthy weight control behaviors: a mediation model.

OBJECTIVE: Children who are overweight or obese are at risk for depression and development of unhealthy weight control behaviors (UWCBs), including using diet pills, purging, or fasting. Explications of pathways leading to UWCBs are needed to prevent the associated negative health outcomes. METHODS: Participants were 106 children/adolescents 8-17 years of age at a pediatric clinic. Measures included child body mass index, the Child Depression Inventory-Short Form, and questionnaires assessing perception of overweight and UWCBs used in the past year. Depression was hypothesized to mediate the relationship between perception of overweight and UWCBs. RESULTS: A bootstrapped mediation model revealed that depressive symptoms mediated the relationship between youth perception of overweight and UWCBs accounting for youth body mass index z-score. The total model explained 24% of the variance in UWCBs. Discussion This study presents a potential mechanism by which youth perception of overweight may influence UWCBs. Longitudinal research is needed to further elucidate the directionality of these relationships.

Are food restriction and pressure-to-eat parenting practices associated with adolescent disordered eating behaviors?

OBJECTIVE: To examine associations between parental pressure-to-eat and food restriction and adolescent disordered eating behaviors, within a sample of parent-adolescent pairs. METHOD: Adolescents (N = 2,231) and their parents (N = 3,431) participated in two, coordinated, population-based studies designed to examine factors associated with weight and weight-related behaviors in adolescents. RESULTS: Overall, higher levels of pressure-to-eat or food restriction were significantly and positively associated with use of disordered eating behaviors among boys. For every one unit increase [Scale Range: 1 (low control) to 4 (high control)] in mothers' food restriction, boys were twice as likely to engage in extreme weight control behaviors (p ≤ .01). Examination of the association between food-related parenting practices and disordered eating behaviors among girls revealed fewer significant associations. However, analyses revealed that for every one unit increase in mothers' food restriction, girls were 1.33 times more likely to engage in extreme weight control behaviors (p = .04). DISCUSSION: Study findings provide evidence of an association between controlling food-related parenting practices and adolescent disordered eating behaviors, particularly in boys. Future longitudinal research is needed to establish directionality of observed associations.

Unhealthy weight control behaviors and health risk behaviors in American youth: a repeated cross-sectional study.

BACKGROUND: Unhealthy weight control behaviors (UWCBs) involve weight control strategies to reduce or maintain weight, such as fasting, taking diet pills, and vomiting or taking laxatives. UWCBs in teenagers can escalate into severe health issues such as eating disorders. Understanding the trends of UWCBs and their association with risk behaviors in teenagers is crucial, as early intervention and prevention strategies are pivotal. METHODS: This study utilized eight waves of the youth risk behavior surveillance system (YRBSS) data from 1999 to 2013. Our primary outcome was UWCBs engagement. We used multinomial logistic models to analyze the association between UWCBs and risk behaviors among adolescents including driving after alcohol consumption, suicide attempts, smoking, alcohol use, and sexual intercourse. RESULTS: Among 109,023 participants, UWCBs prevalence was 16.64%. Body Mass Index (BMI) was significantly associated with UWCBs risk. In addition, we found the intention of weight management confounded the relationship between BMI and UWCBs. The unadjusted logistic regression indicated a monotone-increasing association between BMI and the risk of UWCBs. In contrast, the adjusted logistic regression indicated a U-shaped curve with the lowest (BMI < 17 kg/m2) and highest (BMI > 30 kg/m2) BMI groups having significantly higher odds of engaging in UWCBs compared to the reference BMI group (18.5 ≤ BMI ≤ 24.9 kg/m2). CONCLUSIONS: The intention of weight management confounded the relationship between Body Mass Index (BMI) and the risk of UWCBs. These findings suggest that healthcare interventions for weight management behaviors should be tailored to adolescents with BMI ≥ 25 and BMI < 18.5.

This study looked at unhealthy weight control behaviors (UWCBs) in American teenagers, such as fasting, taking diet pills, or vomiting to control weight. These behaviors can lead to serious health problems, including eating disorders. The research analyzed data from over 100,000 teenagers between 1999 and 2013 to understand the connection between UWCBs and other risky behaviors like drinking alcohol, smoking, and attempting suicide. While previous research suggested that teens with higher body weight were more likely to engage in UWCBs, our findings showed a shift in this relationship after considering the teens' intentions to manage weight. Specifically, teens with very low body weight (BMI < 17) and a strong desire to lose weight had an increased risk of UWCBs. This highlights the need for healthcare providers to focus on the mental health and weight management goals of these teens to prevent harmful behaviors. Additionally, reconsidering the removal of UWCB-related questions from national surveys like YRBSS is important to continue monitoring these behaviors.

Associations of breastfeeding with bulimic behaviors and eating disorders among adolescents.

PURPOSE: To use the lifecourse framework to examine the association between duration of breastfeeding and risk of developing bulimic behaviors or a diagnosed eating disorder. METHOD: Questionnaires were sent every 12-24 months between 1996 and 2005 to 6,436 females and 5,756 males in the Growing Up Today Study, who were 9-14 years at baseline. Duration of breastfeeding was reported by the participants' mothers in 1997. We used generalized estimating equations to estimate the association of breastfeeding with purging, binge eating, engaging in bulimic behaviors, and having a diagnosed eating disorder. RESULTS: Compared to girls who were breastfed for more than 9 months, those who were breastfed for less than 4 months did not have a significantly different prevalence of purging, binge eating, bulimic behaviors, and self-reported history of diagnosed eating disorders. Adjusting for gestational age/birthweight, age, age at menarche, maternal history of an eating disorder, and maternal body mass index, short duration of breastfeeding was not associated with any outcome among the girls [adjusted odds ratios (AOR) ranged from 0.8 to 1.1]. Among the boys, the results showed no significant associations between duration of breastfeeding and purging, binge eating, and self-reported history of diagnosed eating disorder. However, there was a suggestion that boys who had been breastfed for less than 4 months were at a higher risk of engaging in bulimic behaviors [AOR: 1.5, 95% confidence interval (CI), 1.0-2.3]. DISCUSSION: No association was found between duration of breastfeeding and risk of developing bulimic behaviors or a diagnosed eating disorder among girls or boys with the one exception of longer duration of breastfeeding associated with fewer bulimic behaviors in boys. Although there are many benefits to breastfeeding, our data suggest that breastfeeding does not offer any protection against binge eating or purging, nor does it present harmful effects.

Household food insecurity is associated with greater prevalence and 18-month incidence of a range of disordered eating behaviors in a racially and ethnically diverse sample of parents.

This study examined cross-sectional and longitudinal associations between household food insecurity (FI) and a range of disordered eating behaviors (DEBs) and explored whether associations differ by Supplemental Nutrition Assistance Program (SNAP)/Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) participation. Data came from 1120 racially/ethnically diverse parents (Mage = 35.7 ± 7.8 years at baseline) in the Family Matters longitudinal cohort study. Parents reported on household FI and SNAP/WIC participation at baseline, and on past-year restrictive weight-control behaviors (WCBs; e.g., fasting), compensatory WCBs (e.g., self-induced vomiting), and binge eating at baseline and 18-month follow-up. Sociodemographics-adjusted modified Poisson regressions examined baseline household FI in relation to baseline prevalence and 18-month incidence (i.e., new onset) of each type of DEB. Moderation by SNAP/WIC participation was also tested. Household FI affected 29.6 % of participants and was associated with significantly greater baseline prevalence (prevalence ratios ranging from 1.38 to 2.69) and 18-month incidence (risk ratios ranging from 1.63 to 2.93) of each type of DEB examined. The association between household FI and incident compensatory WCBs differed significantly by SNAP/WIC participation, such that household FI significantly predicted new-onset compensatory WCBs at follow-up only among those participating in SNAP/WIC. Results from this study are the first, to our knowledge, to demonstrate that FI is longitudinally associated with restrictive and compensatory DEBs, thereby highlighting FI as a risk factor not only for binge eating, but for a range of DEBs. These findings emphasize the importance of screening for FI in clinical settings and the need to address structural barriers to food security.
