ABSTRACT

Objective To study the prevalence and risk factors of human immunodeficiency virus (HIV) among men who have sex with men (MSM) in Beijing. Methods A sample of 550 MSM was recruited between March and June in 2008 in Beijing. Interviewer-administered interviews were conducted to collect information on demographics and behaviors. Blood samples were collected to test for HIV,syphilis,HBsAg and HCV infections. Chi-square test and logistic regression model were used to identify risk factors associated with HIV infection. Results Of the 550 eligible MSM surveyed,HIV prevalence appeared to be 4.5% (25/550). Data from multivariate logistic regression analysis demonstrated that factors as reporting unprotected anal intercourse with causal male sexual partners in the last month (X~2=11.381,P=0.001),rectal douching after homosexual anal intercourse in the past three months (X~2=5.326,P=0.021),feeling sad in the last month (X~2=8.809,P=0.003) were significantly associated with HIV infection. Conclusion Health education on safer sex behavior and mental health care should be taken to hinder the speed of HIV transmission among MSM.
