Relationship Between Childhood Sexual Abuse and HIV-Related Risks Among Men Who Have Sex with Men: Findings from Mainland China.

Men who have sex with men (MSM) carry the burden of HIV infection in China. Outside of China, a history of childhood sexual abuse (CSA) has been associated with HIV-related risks (behavioral, sexual, and mental health outcomes) among MSM. We therefore evaluated the relationship between CSA and these HIV-related risks among MSM in China. Cross-sectional data were collected via a survey from gay websites and social networking applications from MSM in 30 provinces in mainland China during a 3-month period in 2014 and 2015. Overall, 999 screened MSM who responded to questions on CSA were included. Multinomial logistic regression models-adjusted for sociodemographic confounders-showed that men who reported experiencing regular CSA and contact CSA, respectively, were more likely to use substances (adjusted odds ratio [AOR], 1.91; 95% confidence interval [CI] 1.39-2.62 and AOR, 1.70; 95% CI 1.25-2.31), had a history of sexually transmitted infections (AOR, 1.81; 95% CI 1.29-2.55 and AOR, 1.65; 95% CI 1.18-2.96), had more male sexual partners (AOR, 1.06; 95% CI 1.04-1.09 and AOR, 1.05; 95% CI 1.03-1.08), engaged in more condomless sex with men (AOR, 1.89; 95% CI 1.39-2.56 and AOR, 1.72; 95% CI 1.29-2.30), and experienced more psychological distress (AOR, 1.05; 95% CI 1.02-1.08 and AOR, 1.05; 95% CI 1.03-1.08). Both frequent and contact forms of CSA were positively associated with HIV-related risks among MSM, suggesting that general CSA prevention strategies and interventions are needed to support this population.
