Differential Risk Factors for Unhealthy Weight Control Behaviors by Sex and Weight Status Among U.S. Adolescents.

ABSTRACT: PURPOSE:To determine if previously reported risk factors for the development of unhealthy weight control behaviors differ by sex and weight status using a nationally representative longitudinal sample of adolescents followed through young adulthood. METHODS:We used nationally representative longitudinal cohort data collected from baseline (11-18 years old, 1994-1995, Wave I) and seven-year follow-up (18-24 years old, 2001-2002, Wave III) of the National Longitudinal Study of Adolescent to Adult Health (Add Health). We examined potential risk factors (adverse childhood events and adolescent family, school, body image, and mental health factors) for the development of unhealthy weight control behaviors including vomiting, fasting/skipping meals, or laxative/diuretic use to lose weight at seven-year follow-up in young adulthood. RESULTS:Of the 14,322 included subjects, 11% reported unhealthy weight control behavior at follow-up in young adulthood, with the highest proportion (23.7%) among overweight/obese females and the lowest proportion (3.7%) among underweight/normal weight males. All adolescent family factors were significantly associated with unhealthy weight control behaviors in underweight/normal weight females, whereas none were significantly associated in overweight/obese males. Similar trends were noted for adverse childhood events, and adolescent school and community factors. Adolescent self-perception of being overweight was associated with young adult unhealthy weight control behaviors among all subgroups. CONCLUSIONS:Risk factors for unhealthy weight control behaviors may differ based on sex and weight status. Screening, prevention, and treatment interventions for unhealthy weight control behaviors in adolescents and young adults may need to be tailored based on sex and weight status.

Project description:BackgroundBody 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.Method549 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.ResultsDating 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.ConclusionsThis 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.

Project description:This study aimed to identify associations among self-perceived weight status, accuracy of weight perceptions, and weight control behaviors, including both healthy and unhealthy behaviors, in a large, nationally representative sample from an East Asian country. Data were collected from the 2016 Korean Study of Women's Health Related Issues, a population-based, nationwide survey. Accurate weight perceptions were investigated by comparing body mass index (BMI) categories, based on self-reported height and weight, and weight perceptions. Weight control behaviors over the previous 12 months were additionally surveyed. Odds ratios (ORs) and 95% confidence intervals (CIs) are presented as an index of associations. Among normal weight, overweight, and obese women, 12.8%, 44.3%, and 17.4% under-assessed their weight; 17.9% of normal weight women over-assessed their weight. Both weight status according to BMI category and weight perceptions were strongly associated with having tried to lose weight. Exercise and diet (ate less) were the most commonly applied weight control behaviors. Misperception of weight was related to more unhealthy weight control behaviors and less healthy behaviors: Women who under-assessed their weight showed a lower tendency to engage in dieting (OR = 0.57, 95% CI = 0.43-0.75) and a greater tendency to fast/skip meals (OR = 1.47, 95% CI = 1.07-1.99). Meanwhile, normal weight or overweight women who over-assessed their weight were more likely to have engaged in fasting/skipping meals or using diet pills (OR = 5.72, 95% CI = 2.45-13.56 for fasting/skipping meal in overweight women; OR = 1.62, 95% CI = 1.15-2.29 and OR = 3.16, 95% CI = 1.15-8.23 for using diet pills in normal and overweight women). Inaccuracy of weight perceptions in any direction (over/under) were related to more unhealthy weight control behaviors and less healthy weight control behaviors, especially in normal and overweight women.
