目的研究性少数人群饮食失调发生率的上升趋势；然而，很少有研究调查了这一人群中饮食失调诊断的差异。本研究旨在研究DSM-5定义的ed的终生患病率，包括神经性厌食症（AN）、神经性贪食症（BN）和暴饮暴食症（BED）作为性取向的功能。然后，我们比较了基于感知歧视经历的ed患病率。方法选取参加2012-2013年全国酒精及相关疾病流行病学调查iii的具有全国代表性的美国成年人样本（N = 35,995）完成结构化诊断访谈。结果性少数人群的ed患病率明显高于异性恋人群：AN = 1.71% （SE = 0.50）比0.77% (SE = 0.07), BN = 1.25% （SE = 0.37）比0.24% (SE = 0.03), BED = 2.17% （SE = 0.52）比0.81% （SE = 0.05）。在调整社会人口学变量后，性少数群体终身诊断AN（调整优势比[AOR] = 1.93）、BN （AOR = 3.69）和BED （AOR = 2.32）的几率显著更高。性少数群体报告有感知到的歧视经历的AN患病率显著高于没有感知到歧视的人群：3.78% （SE = 1.43）对0.82% (SE = 0.33)；Aor = 5.06。在感知歧视方面，BN和BED的患病率没有显著差异。研究结果表明，性少数群体受到ed的影响不成比例。需要进一步的研究来更好地了解导致这些差异和EDs风险增加的机制。
Objective The increased occurrence of disordered eating behaviors among sexual minorities is well established; however, few studies have examined disparities in eating disorder diagnoses among this population. This study sought to examine lifetime prevalence estimates of DSM-5 defined EDs, including anorexia nervosa (AN), bulimia nervosa (BN), and binge-eating disorder (BED) as a function of sexual orientation. We then compared prevalence of EDs based on experiences with perceived discrimination.Method A nationally representative sample of U.S. adults (N = 35,995) participating in the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions-III completed structured diagnostic interviews.Results Prevalence rates were significantly higher among sexual minorities than heterosexual respondents for all EDs: AN = 1.71% (SE = 0.50) versus 0.77% (SE = 0.07), BN = 1.25% (SE = 0.37) versus 0.24% (SE = 0.03), BED = 2.17% (SE = 0.52) versus 0.81% (SE = 0.05). Odds of lifetime diagnosis were significantly greater among sexual minorities for AN (adjusted odds ratio [AOR] = 1.93), BN (AOR = 3.69), and BED (AOR = 2.32), after adjusting for sociodemographic variables. Sexual minorities reporting experiences with perceived discrimination had significantly higher prevalence of AN than those not endorsing perceived discrimination: 3.78% (SE = 1.43) versus 0.82% (SE = 0.33); AOR = 5.06. There were no significant differences in prevalence of BN or BED by perceived discrimination.Discussion Findings indicate that sexual minorities are disproportionately affected by EDs. Further research is needed to better understand mechanisms contributing to these disparities and heightened risk for EDs.
