OBJECTIVE: To understand the knowledge, risk behaviors and HIV prevalence in men who have sex with men (MSM) in thirteen cities. METHODS: Target samples were chosen using the snowball-rolling method, with transverse KABP and HIV-antibody testing developed for those MSM in thirteen cities of Yunnan. RESULTS: A total of 1237 valid questionnaires and 1129 blood samples were collected. Basic knowledge on HIV and the rate of the response was 93.2%. 81.1% of the respondents had anal sex with male partners in the last six months, of them 49.7% could persistently using condoms in each anal sex episode. 29.0% of the respondents had sex with female partners in the last six months. The HIV prevalence among the studied MSM was 8.2% and the prevalence of syphilis among them was 3.9%. Most risky factors of those MSM infected by HIV would include: not persistently use condom when having sex and co-infection of syphilis. CONCLUSION: Both rates of HIV infection associated risk behaviors and HIV prevalence were high in MSM under study that called for more work on HIV prevention and control MSM in Yunnan.
