First study to estimate the prevalence of alcohol using AUDIT among MSM in Chongqing.

Finding provided evidences of associations of alcohol use with HIV-risky behaviors.

Unmarried MSM but planning to marry with a woman were more likely to drink alcohol.

MSM with low self-efficacy and/or high stigma were more likely to drink alcohol.

Alcohol-related sex might be one of the main reasons for such a high HIV prevalence.
