Epidemiological data support that sexual minorities (SM) report higher levels of eating pathology. Theories suggest these disparities exist due to stressors specific to belonging to a minority group; however, few studies have specifically explored differences between SM and heterosexual individuals in clinical eating disorder samples. Thus, the present study compared SM and heterosexual patients with eating disorders on demographic characteristics and eating disorder and psychological outcomes during day hospital treatment.
Patients (N = 389) completed surveys of eating pathology, mood, anxiety, and skills use at treatment admission, 1-month post-admission, discharge, and 6-month follow-up. Overall, 19.8% of patients (n = 79) identified as SM, while 8.0% (n = 32) reported not identifying with any sexual orientation. SM were more likely to present across genders (17.7% of females, 24.2% of males, 33.3% of transgender patients, and 87.5% of nonbinary patients).
SM patients were significantly more likely to endorse major depressive disorder, panic disorder, and self-harm at admission than their heterosexual counterparts. Multilevel models demonstrated that across time, SM patients demonstrated greater eating pathology, emotion dysregulation, depressive symptoms, and anxiety symptoms. Significant interactions between sexual orientation and time were found for eating pathology and emotion dysregulation, such that although SM patients started treatment with higher scores, they improved at a faster rate compared to heterosexual patients.
Consistent with minority stress theory, SM patients report greater overall eating disorder and comorbid symptoms. Importantly, results do not support that there appear to be significant disparities in treatment outcome for SM patients in this sample of day hospital patients.
流行病学数据支持性少数群体(SM)报告更高水平的进食障碍。理论表明,这些差异的存在是由于属于少数群体的特定压力源;然而,很少有研究专门探讨了临床进食障碍样本中 SM 和异性恋个体之间的差异。因此,本研究比较了在日间医院治疗中,SM 和异性恋进食障碍患者在人口统计学特征、进食障碍和心理结果方面的差异。
患者(N=389)在治疗入院时、入院后 1 个月、出院时和 6 个月随访时完成了进食障碍、情绪、焦虑和技能使用的调查。总体而言,19.8%的患者(n=79)认为自己是 SM,而 8.0%(n=32)表示不认同任何性取向。SM 更有可能出现在不同性别中(17.7%的女性、24.2%的男性、33.3%的跨性别患者和 87.5%的非二元性别患者)。
SM 患者在入院时比异性恋患者更有可能被诊断为重度抑郁症、惊恐障碍和自残。多层次模型表明,SM 患者在整个时间内表现出更严重的进食障碍、情绪失调、抑郁症状和焦虑症状。在进食障碍和情绪失调方面,发现了性取向和时间之间的显著交互作用,即尽管 SM 患者开始治疗时的分数较高,但他们的改善速度比异性恋患者更快。
与少数群体应激理论一致,SM 患者报告了更严重的整体进食障碍和共病症状。重要的是,结果并不支持在这个日间医院患者样本中,SM 患者的治疗结果存在明显差异。
