HIV prevalence among men who have sex with men (MSM) has increased rapidly in China. Behavioral and biological interventions are key to controlling the spread of HIV in the MSM population and the primary strategy for reducing the spread of AIDS in China. The purpose of this study is to investigate the prevalence of HIV among MSM in Henan province and to assess their knowledge levels and risk behaviors related to HIV/AIDS.
A cross-sectional survey was conducted among 388 MSM in 2010 in Zhengzhou City, Henan province, China.
Of the 388 respondents, 13.1% were infected with HIV and 10.3% were infected with syphilis. The results of multivariate analysis showed that participants who had a history of being infected by syphilis were more than 4 times more likely to be HIV positive (AOR=4.91; 95% CI: 1.70 to 12.02). For those who were residents from other provinces, the risk of HIV infection was 5.53 times higher (OR=5.53, 95% CI: 1.14, 6.25). Receipt of condoms (AOR = 0.15; 95% CI: 0.02 to 0.87), consistent condom use during last intercourse with a male (AOR=0.35; 95% CI: 0.14 to 0.87), and consistent condom use during last intercourse with a female (AOR=0.16; 95% CI: 0.08 to 0.90) were associated with a lower risk of HIV infection.
The study suggests that some intervention strategies, including education intervention, condom promotion and distribution, and HIV counseling and testing are necessary to control HIV infection among MSM.
