Variables were evaluated by using RSAT and SAS software. Results Mean age of the participants was 30.6 years, with 96.0% of them as Han ethnicity and 68.5% having had at least high school or higher education level. 72.8% of them were unmarried, with 61.7% of them identified themselves as homosexual, 61.2% had 〉 1 male partners in the past six months, and the prevalence of UAI was 42.0%. Significant bivariate predictors of UAI would include condom use social norms score, role for anal sex with male sex partner, number of male sexual partners in the past 6 months and amount of alcohol consumed. In multivariable analysis, UAI was associated with a higher condom use social norms score （A OR = 1.2,95 % CI： 1.1 - 1.3）, receptive anal intercourse （AOR=2.0, 95%CI： 1.3-3.2） and drinking alcohol more than 3 times per month in the past 12 months （AOR=I.6, 95%C1： 1.1-2.5）.
