Purpose
Research is lacking on psychological distress and disorder among sexual minority medical students (students who identify as non-heterosexual). If left unaddressed, distress may result in academic and professional difficulties and undermine workforce diversity goals. The authors compared depression, anxiety, and self-rated health among sexual minority and heterosexual medical students.
Method
This study included 4,673 first-year students with self-reported sexual orientation data in the fall 2010 baseline survey of the Medical Student Cognitive Habits and Growth Evaluation Study, a national longitudinal cohort study. The authors used items from published scales to measure depression, anxiety, self-rated health, and social stressors. They conducted bivariate and multivariate analyses to estimate the association between sexual identity and depression, anxiety, and self-rated health.
Results
Of the 4,673 students, 232 (5.0%) identified as a sexual minority. Compared with heterosexual students, after adjusting for relevant covariates, sexual minority students had greater risk of depressive symptoms (adjusted relative risk [ARR] =1.59 [95% CI, 1.24–2.04]) anxiety symptoms (ARR = 1.64 [1.08–2.49]), and low self-rated health (ARR = 1.77 [1.15–2.60]). Sexual minority students were more likely to report social stressors, including harassment (22.7% vs 12.7%, P < .001) and isolation (53.7% vs 42.8%, P = .001). Exposure to social stressors attenuated but did not eliminate the observed association between minority sexual identity and mental and self-reported health measures.
Conclusions
First-year sexual minority students experience significantly greater risk of depression, anxiety, and low self-rated health than heterosexual students. Targeted interventions are needed to improve mental health and well-being.
