目的：体重歧视虽然普遍存在，但尚未得到充分研究，并且与青少年和成年人的饮食失调行为（DEB）有关。性少数人群患DEB的风险较高，但对体重歧视在这种风险升高中的作用知之甚少。研究对象为1257名性少数群体男女（年龄18-31岁），来自美国“今日成长”研究队列。在过去的一年中，我们研究了体重歧视受害与三种DEB之间的横断面关联：不健康的体重控制行为、暴饮暴食和暴饮暴食。使用针对潜在混杂因素进行调整的广义估计方程来估计患病率（pr）和95%置信区间（ci）。结果3 / 10的参与者（31%）报告了基于体重的歧视受害者。与没有体重歧视的性少数年轻人相比，报告体重歧视的性少数年轻人在不健康体重控制行为（PR [95% CI]: 1.92[1.35, 2.74]）、暴饮暴食（3.15[2.24,4.44]）和暴食（3.92[2.51,6.13]）方面的相对患病率更高。在调整BMI后，暴饮暴食和暴饮暴食的关系仍然很明显。体重歧视的作用，以及它与其他形式的压力源对性少数年轻人的影响，必须包括在努力中，以促进这一服务不足的人群的饮食失调预防。在这项研究中，十分之三的性少数年轻人经历过基于体重的歧视，这是一种常见但尚未得到充分研究的歧视形式。经历过体重歧视的性少数年轻人比没有经历过体重歧视的人有更大的饮食失调风险。这些发现表明，体重歧视可能是性少数年轻人饮食失调的一个重要且可预防的风险因素。
ObjectiveThough 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.
