Method: A total of 807 MSM were recruited using respondent-driven sampling from four cities in northeastern China. GRSEs were measured using the Gay Related Stressful Life Events Scale, and depressive symptoms were assessed using the Self-Rating Depression Scale (SDS). Results: A total of 26.0% of study participants experienced GRSEs in the past three months, and the average SDS score was lower than the previously reported national average for China. The study participants had significantly elevated risks of depression (SDS score ≥ 53) due to recent troubles with a boss (OR = 4.92, 95% CI = 1.87–12.97) or a workmate (OR = 3.68, 95% CI = 1.52–8.88), loss of a close friend (OR = 2.41, 95% CI = 1.39–4.18), argument with a close friend (OR = 2.07, 95% CI = 1.33–3.22), and being physically assaulted (OR = 2.08, 95% CI = 0.98–4.43). Arguments with family members or classmates had no significant effect on depression. Multiple logistic regression analysis showed that the number of GRSEs, a lower level of education, more advanced age, and HIV infection significantly increased the risk of depression. Conclusions: There are large differences in the associations of different types of GRSEs with depressive symptoms. Reducing the stigmatization and discrimination toward MSM in all social environments and improving the capability of MSM to cope with different types of GRSEs may improve their emotional wellbeing.
