Eating disorders (EDs) have traditionally been studied among heterosexual cisgender women, but recent research highlights a higher prevalence in LGBTQIA+ individuals.
This study aims (1) to investigate the association between different groups based on gender identity and sexual orientation (GISO) and experiencing eating symptoms, and (2) to explore the extent to which self-perceived discrimination and adverse conditions explain this association.
We administered an online survey to assess eating symptoms using the Eating Disorder Examination Questionnaire (EDE-Q 6.0) and measures of self-perceived discrimination and adverse conditions. Multistep logistic regressions were employed to analyze the associations between GISO and eating symptoms, initially unadjusted, then adjusted for sociodemographic variables, and finally adjusted for self-perceived discrimination and/or adverse conditions.
A total of 560 adults aged 30 ± 10.9 years old were included. After adjusting for socio-demographics all groups were more likely to experience eating symptoms compared to heterosexual men, with odds ratios (ORs) of 5.7 [95% CI: 1.3, 24.3] for cisgender heterosexual women, 6.7 [95% CI: 1.5, 29.8] for cisgender non-heterosexual women, and 9.3 [95% CI: 1.8, 47.5] for non-cisgender individuals. After adjusting for self-perceived discrimination and adverse conditions, the associations for women were attenuated, while the associations for non-cisgender individuals were no longer significant.
This study (1) confirms that sexual and gender minorities may be at higher risk for EDs, and (2) suggests that discrimination and adverse conditions may contribute to the higher prevalence of eating symptoms in this population. Additional research is needed to investigate these minority stressors as they may represent targets for effective interventions to prevent eating symptoms in the LGBTQIA+ community.
饮食失调传统上是在异性恋顺性别女性中进行研究的,但最近的研究表明,LGBTQIA+群体中的患病率更高。
本研究旨在(1)调查基于性别认同和性取向(GISO)的不同群体与出现饮食症状之间的关联,以及(2)探讨自我感知的歧视和不利状况在多大程度上解释了这种关联。
我们进行了一项在线调查,使用饮食失调检查问卷(EDE-Q 6.0)评估饮食症状,并测量自我感知的歧视和不利状况。采用多步逻辑回归分析GISO与饮食症状之间的关联,最初未进行调整,然后对社会人口统计学变量进行调整,最后对自我感知的歧视和/或不利状况进行调整。
共纳入560名年龄在30±10.9岁的成年人。在对社会人口统计学进行调整后,与异性恋男性相比,所有群体出现饮食症状的可能性更高,顺性别异性恋女性的优势比(OR)为5.7 [95%置信区间:1.3,24.3],顺性别非异性恋女性为6.7 [95%置信区间:1.5,29.8],非顺性别个体为9.3 [95%置信区间:1.8,47.5]。在对自我感知的歧视和不利状况进行调整后,女性的关联减弱,而非顺性别个体的关联不再显著。
本研究(1)证实性少数和性别少数群体可能患饮食失调的风险更高,(2)表明歧视和不利状况可能导致该人群中饮食症状的患病率较高。需要进一步研究这些少数群体压力源,因为它们可能是预防LGBTQIA+群体饮食症状的有效干预目标。
