Prevalence and related risk behaviors of HIV, syphilis, and anal HPV infection among men who have sex with men from Beijing, China.

Specific risk behaviors related to different sexually transmitted infections have not been widely evaluated among men who have sex with men in China. In the present study, a total of 302 MSM were recruited from Beijing with a prevalence of HIV, syphilis, and anal HPV infection as 9.9, 19.2 and 71.4%, respectively. Lower education level was observed to be related to higher infection rate of HIV and syphilis. "Ever found sexual partners in gay venues" was significantly associated with HIV infection as well. "Taking anilinction as regular sexual behavior" was observed to be a significant predictor for anal HPV infection.
