Methods A questionnaire survey was conducted among the MSM in Taiyuan from March to August,2013 to collect their basic information, including demographic characteristics, sexual behaviors history, sexual partner number, awareness of AIDS related knowledge and behavior intervention acceptance. Blood samples were collected from them for the test of HIV, syphilis and HCV antibodies. Chi square test and logistic regression model were used to identify risk factors related with HIV infection. Results Of the 255 eligible MSM surveyed, 54.12% were self-identified as homosexulity and 43.14% were bisexuality. The MSM whose first sexual partner was male accounted for 70.98%, and those whose first sex partner was female accounted for 29.02%. The MSM who had both active and passive anal sex accounted for 45.88%. The MSM with regular sexual partners accounted for 55.29%, and those without regular sex partners accounted for 44.71%. During the past 6 months, The MSM who had homosexual behaviors accounted for 85.49%, the MSM who had commercial homosexual behaviors accounted for 5.96% and the MSM who had heterosexual behaviors accounted for 21.57%. The median of sexual partner number was 2(1-200). The MSM who sought male partner through internet accounted for 71.56%. The condom use rate was low in all sexual behaviors. The HIV infection rate was 18.90%, syphilis prevalence was 7.48%, HCV infection rate was 0.72%, co-infection rate of HIV and syphilis was 2.36%. The awareness rate of AIDS related knowledge was 91.76%. The multivariate logistic regression analysis indicated that age﹥25 years,﹥2 years local residence(OR=0.76,95%CI:0.62-0.94)and sexually transmitted infection history(OR=3.818,95%CI:1.11-15.02)were significantly related with HIV infection. Conclusion MSM are sexual active and with multiple sex partners. High risk behaviors are common and HIV/STDs transmit among them. It is necessary to strengthen risk behavior intervention and promote condom use among them to reduce the spread of HIV infection.
