Abstract：Objective To investigate the current status of AIDS-related knowledge and behavior among men who have sex with men (MSM), and to analyze the protective factors influencing their sexual behavior. Methods Based on the informed and consent principle, snowball sampling method was used to recruit MSM volunteers in fixed places of 9 counties (cities, districts) of Mianyang City from April to October, 2014. A self-administered anonymous questionnaire survey and serological test were conducted. Chi-square test was used to compare rates. And non-conditional logistic regression analysis was employed to study the protective factors influencing sexual behavior among MSM. Results A total of 1,097 MSM volunteers were investigated, and the awareness rate of AIDS-related knowledge was 99.0% (1,086/1,097). Anal sex, commercial sex and heterosexual sex occurred respectively in 85.6%(939/1,097), 1.7% (16/939) and 8.2%(90/1,097)of the participants in the last 6 months, with protective sexual behavior respectively in 68.7%(640/932), 37.5%(6/16)and 24.4%(22/90)in the last 6 months as well as 89.3%(832/932), 62.5%(10/16), 61.1%(55/90)in the last sexual behavior. There were statistically significant differences in the incidence rates of protective anal sex and protective heterosexual sex among different regions (both P<0.05). HIV infection rates in the groups with protective anal sex and unprotected anal sex in the last 6 month were 1.6%(10/640)and 8.6%(25/292)respectively(P=0.000). Multi-factor analysis showed that factors promoting protective sex among the MSM were educational background with high school ortechnical secondary school (OR=1.621, 95%CI:1.028-2.555, P=0.038), local residence time ≥3 months (OR=8.353, 95%CI:1.666-41.878, P=0.010), awareness of AIDS-related knowledge (OR=1.774, 95%CI: 1.064-2.960, P=0.028) and receiving preventive services in the last year (OR=3.690, 95%CI:2.591-5.236, P=0.000), while the risk factor was the times of anal sex in the last week ≥2 (OR=0.516,95%CI:0.363～0.733,P=0.000). Conclusions The awareness rate of AIDS-related knowledge in the MSM in Mianyang City in 2014 is high. The incidence of protective sex in different regions is diverse, and the overall level is not high. It is affected by educational background, local residence time , AIDS-related knowledge awareness, preventive services and frequency of anal sex. So targeted behavior interventions should be taken.
