Objective To examine high-risk behaviors,especially unprotected anal intercourse (UAI),among HIV sero-positive men having sex with men (MSM),and to identify the factors associated with these risk behaviors. Methods The participants in this survey were selected from the "Chinese National Pilot Program on MSM and HIV/AIDS" by respondent driven sampling (RDS) and snowball sampling approaches. An interviewer-administered questionnaire was developed to collect information regarding demographic characteristics,high-risk behaviors and others related items. Results A total of 754 eligible participants were interviewed. The syphilis infection rate was 28.9% and the prevalence of UAI in the previous 6 months was 67.4%. Factors associated with UAI included residence in the study city for more than 6 months; frequent visit to gay bathrooms,parks or other gay venues to look for sex partners; and deprivation of any HIV/AIDS related health services in the previous year. Conclusion Syphilis and UAI prevalence among MSM living with HIV are high,and targeted interventions should be urgently provided for this population group.
