Objective

In a national sample of college students, the current study aimed to: 1) examine differences in probable diagnoses of EDs (i.e., anorexia nervosa (AN), clinical/subthreshold bulimia nervosa (BN), or binge eating disorder (BED)) and weight and shape concerns by sexual orientation and gender identity, and 2) examine differences in ED chronicity and probable comorbid psychiatric diagnoses by sexual orientation and gender identity.

Method

Students across nine U.S. universities completed an online screener for DSM-5 clinical or subthreshold ED diagnoses, comorbid depression and anxiety disorders, and self-reported ED chronicity. Self-reported sexual orientation and gender identity were also collected. Tukey-corrected logistic and linear regressions examined differences in outcomes separately by sexual orientation and gender identity, adjusting for age, race, and ethnicity.

Results

A total of 8,531 students (24% sexually diverse (SD); 2.7% gender diverse (GD)) were studied. Students who identified as bisexual or other sexual orientation reported significantly greater odds of a probable ED diagnosis and greater elevations in weight and shape concerns compared to heterosexual students. Cisgender female students and GD students reported significantly greater odds of a probable ED diagnosis and greater elevations in weight and shape concerns compared to cisgender male students. Some SD students and GD students who met criteria for probable EDs were also more likely to report chronic ED symptoms and probable comorbid psychiatric diagnoses compared to heterosexual students and cisgender males, respectively.

Discussion

Some SGD students may be at heightened risk for EDs, highlighting the need to identify mechanisms that contribute to disparities.

在全国大学生样本中通过性取向和性别认同表征饮食失调诊断和相关结果

客观的

在全国大学生样本中，目前的研究旨在：1）检查 ED 的可能诊断差异（即神经性厌食症 (AN)、临床/亚阈值神经性贪食症 (BN) 或暴食症 (BED)）和性取向和性别认同对体重和体型的担忧，以及 2）通过性取向和性别认同检查 ED 慢性病和可能的共病精神病诊断的差异。

方法

来自美国九所大学的学生完成了 DSM-5 临床或亚阈值 ED 诊断、共患抑郁症和焦虑症以及自我报告的 ED 慢性病的在线筛查。还收集了自我报告的性取向和性别认同。Tukey 校正逻辑回归和线性回归分别检查了性取向和性别认同的结果差异，并调整了年龄、种族和民族。

结果

共研究了 8,531 名学生（24% 的性别多样化（SD）；2.7% 的性别多样化（GD））。与异性恋学生相比，被认定为双性恋或其他性取向的学生报告了可能被诊断为 ED 的几率显着增加，体重和体型问题也更严重。与顺性别的男学生相比，顺性别的女学生和 GD 学生报告了可能被诊断为 ED 的几率显着增加，并且体重和体型问题的升高也更大。与异性恋学生和顺性别男性相比，一些符合可能 ED 标准的 SD 学生和 GD 学生也更有可能报告慢性 ED 症状和可能的共病精神病诊断。

讨论

一些 SGD 学生可能面临更高的 ED 风险，强调需要确定导致差异的机制。
