Weight‐based discrimination and disordered eating behaviors in a cohort of U.S. sexual minority young adults

Abstract

AbstractObjectiveThough prevalent, weight‐based discrimination is understudied and has been linked to disordered eating behaviors (DEB) among adolescents and adults. Sexual minority populations experience elevated risk of DEB, but little is known about the role of weight discrimination in this elevated risk.MethodsParticipants were 1257 sexual minority women and men (ages 18–31 years) in the US Growing Up Today Study cohort. We examined cross‐sectional associations between weight discrimination victimization and three DEB in the past year: unhealthy weight control behaviors, overeating, and binge eating. Generalized estimating equations, adjusted for potential confounders, were used to estimate prevalence ratios (PRs) and 95% confidence intervals (CIs).ResultsThree in 10 participants (31%) reported weight‐based discrimination victimization. Sexual minority young adults who reported weight‐based discrimination had greater relative prevalence of unhealthy weight control behaviors (PR [95% CI]: 1.92 [1.35, 2.74]), overeating (3.15 [2.24, 4.44]), and binge eating (3.92 [2.51, 6.13]), compared with those who reported no weight‐based discrimination. Associations with overeating and binge eating remained significant after adjusting for BMI.DiscussionThe role of weight‐based discrimination, and its intersections with other forms of stressors for sexual minority young adults, must be included in efforts to advance eating disorder prevention for this underserved population.Public SignificanceThree in 10 sexual minority young adults in this study had experienced weight‐based discrimination, a common but understudied form of discrimination. Sexual minority young adults who experienced weight‐based discrimination were at greater risk of disordered eating behaviors than those who had not experienced weight‐based discrimination. These findings suggest that weight‐based discrimination may be an important—and preventable—risk factor for disordered eating behaviors among sexual minority young adults.
