Methods The study subjects were recruited from non-governmental organizations by using a snowball and peer-recommended sampling method for a questionnaire survey. The HIV positive samples were screened by using saliva rapid test and confirmed with Western blot test, logistic regression analysis was used to analyze the influencing factors for HIV infection. Results A total of 1 906 MSM were surveyed. Saliva rapid test indicated that 96 MSM were HIV positive (5.04%), in which 45 were confirmed by Western blot test (2.36%). Only 110 MSM (5.77%) were aware of the HIV infection status of sexual partners before sexual intercourse, 1 054 MSM (55.30%) had indifferent attitudes to the HIV infection status of sexual partners, 649 MSM (34.05%) believed that it was impossible for them to be infected with HIV and 1 079 MSM (56.61%) never thought about this problem. Multivariate analysis showed that using no condom (OR=4.545, 95%CI:1.093-18.894) or occasional use of condom (OR=3.134, 95%CI:1.133-8.666) in anal sex during past 6 months, receiving no HIV test (OR=37.027, 95%CI:10.928-125.459), receiving only 1-2 HIV tests in the past (OR=12.291, 95%CI:3.338-45.254), never thinking about HIV infection (OR=5.792, 95%CI:2.271-14.771) were the brisk factors for HIV infection.
