Current heterosexual marriage is associated with significantly decreased levels of anxiety symptoms among Chinese men who have sex with men.

Background: The high heterosexual marriage rate could be a 'double-edge' sword for the emotional health of Chinese men who have sex with men (MSM). The aim of this study was to determine if current marriage and breakdown of marriage (divorce) have different effects on the mental health of Chinese MSM. Methods: Eight hundred seven MSM were recruited using respondent-driven sampling from four cities in northeastern China. Gay-related stressful events (GRSE) were measured using the Gay Related Stressful Life Events Scale; social support was measured by the Social Support Rating Scale (SSRS); and depressive and anxiety symptoms were assessed using the Self-Rating Depression Scale (SDS) and Self-Rating Anxiety Scale (SAS), respectively. Results: Of the study participants, 13.4% were married to women and 4.5% were divorced. The rates of marriage or divorce were 35.3 and 75.8% for participants 30–39 and > 40 years of age, respectively. The current married MSM had the highest SDS (50.0 ± 10.9) and SSRS (35.8 ± 8.6) levels, but the lowest SAS (38.7 ± 12.1) levels. Divorced MSM had the highest SAS (44.4 ± 9.6) and lowest SSRS (30.8 ± 8.1) levels. Age, GESE number, and HIV infection were predictors for SDS and SAS, and current marriage was associated with significantly decreased level of SAS (β = − 0.136, P = 0.001) based on multiple linear analysis. Conclusions: Current marriage is associated with significantly decreased levels of anxiety symptoms among Chinese MSM. More studies are needed to understand the mechanisms underlying the effects of different marriage status on the emotional distress of Chinese MSM. [ABSTRACT FROM AUTHOR]
