[Study on the relationship between behavioral factors, psychological status and HIV infection among men who have sex with men in Beijing.].
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 (chi(2) = 11.381, P = 0.001), rectal douching after homosexual anal intercourse in the past three months (chi(2) = 5.326, P = 0.021), feeling sad in the last month (chi(2) = 8.809, P = 0.003) were significantly associated with HIV infection.


CONCLUSIONS
Health education on safer sex behavior and mental health care should be taken to hinder the speed of HIV transmission among MSM.
