Methods HIV positive MSM who known that they had been infected with HIV for more than 6 months and accepted follow up services were recruited by convenience sampling method in Chengdu 2015. Semi-structured questionnaire was used to collect their information, such as demographic characteristics, antiviral therapy and sexual behavior characteristics etc. Logistic regression model was used for univariate and multivariate analyses. Results A total of 330 HIV-positive MSM were recruited, 201 eligible MSM were interviewed. The prevalence of UAI in recent six months was 18.41% (37/201). The results of multivariate logistic regression analysis revealed that the number of anal intercourse with male ≥ 3 in last month (OR=6.22, 95%CI:1.88-20.56), low education level (OR=7.29, 95%CI:1.36-39.16), married, divorced or widowed status (OR=4.65, 95%CI:1.13-19.17), homosexual cohabitation (OR=3.32, 95%CI:1.01-10.95) were the risk factors related with UAI among the HIV-positive MSM.
