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.
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.
Cross-sectional nationally representative data collected from Wave III of the National Longitudinal Study of Adolescent to Adult Health (Add Health).
Young adults ages 18-24 years old.
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.
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.
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.
临床和社区样本表明，在被归类为超重或肥胖的青少年和年轻人中，饮食障碍（EDs）和饮食障碍行为（DEBs）可能同时存在。
使用全国代表性样本确定被归类为超重或肥胖的年轻成年人中 EDs 和 DEBs 的患病率，并根据性别、种族/族裔、性取向和社会经济地位特征来描述患病率的差异。
横断面全国代表性数据来自青少年到成人健康纵向研究的第三波（Add Health）。
18-24 岁的年轻人。
ED 诊断和 DEBs（自我报告的暴食或不健康的体重控制行为，包括呕吐、禁食/不吃正餐、或使用泻药/利尿剂减肥）。协变量：年龄、性别、种族/族裔、性取向、体重状况和教育程度。
在样本中的 14322 名年轻人中，48.6%的人处于超重或肥胖的体重状态。与体重状况被归类为体重不足或正常的年轻人相比，体重状况被归类为超重或肥胖的年轻人报告了更高的 DEBs 发生率（女性为 29.3%比 15.8%，男性为 15.4%比 7.5%）。逻辑回归分析表明，与男性相比，女性发生 DEBs 的可能性高 2.32 倍（95%置信区间 2.05-2.61）；与白人相比，亚裔/太平洋岛民高 1.66 倍（1.23-2.24）；与异性恋相比，同性恋或双性恋高 1.62 倍（1.16-2.26）；与高中或以下相比，高中以上教育程度高 1.26 倍（1.09-1.44）；与正常体重相比，肥胖高 2.45 倍（2.16-2.79），调整所有协变量后。
DEBs 的高患病率，特别是在被归类为超重或肥胖的年轻成年人中，突出表明需要在该人群中对 DEBs 进行筛查、转介和量身定制的干预措施。
