HIV/STD prevalence among MSM in Chengdu, China and associated risk factors for HIV infection

Background: Limited information indicated that HIV prevalence among MSM in Chengdu has been increasing in the last few years, as well as in other large cities in China.

Methods: A cross-sectional study using the snow-ball sampling method was conducted from March to July, 2007 in Chengdu. Participants were asked to complete a questionnaire about sexual history, high risk behaviors, STD infection history, HIV knowledge and testing, and an assessment of depression. Blood samples were taken for antibody testing for HIV, HSV-2, and syphilis.

Results: A total of 538 MSM were recruited to the study among whom 513 (95.4%) consented to participant. HIV, HSV-2 and syphilis prevalence were 9.1%, 24.7%, and 28.1%, respectively. The rate of consistent condom use was low and varied by types of sexual partners. The highest was with casual male partners (38.6%) and the lowest was with wife or girl friend (17.8%). Only 23.4% of participants gave the right answers to all five questions of how to use condoms properly. Money boys (MB) were almost 5 times more likely to be infected with HIV. Other factors associated with HIV infection included being infected with either HSV or syphilis, not knowing how to use condoms properly, and had lived in Chengdu for more than 5 years.

Conclusions: STD infections were high among MSM in Chengdu, and significantly increased the risk for being infected with HIV. To prevent HIV/STDs, promotion campaigns of condom use are needed not only to boost the frequency of condom use, but also to educate MSM about proper condom use. Certain subpopulations, such as those infected with STDs or who engage in commercial sex, require more attention and intensive intervention. To promote HIV VCT among MSM, more information about where to be tested and how to cope with positive results should be disseminated throughout the population.
