[Epidemiological study on the status of HIV/STDs and relative behaviors among MSM in Beijing].
OBJECTIVE
To understand the infected status of human immunodeficiency virus (HIV), sexually transmitted disease (STD) and relative risk behaviors of men who have sex with men (MSM) in Beijing.


METHODS
Respondent-driven sampling (RDS) was adopted to recruit target population and to conduct behavior and serological studies among MSM. RDSAT 5.5 was used to analyze data.


RESULTS
Among 427 MSM, the age distribution was as follows: below 30 and less than 35 were 65.4% and 81.0% respectively. 69.2% (95% CI: 63.9-75.5) of them had 12 years or less of education. 73.3% (95% CI: 66.7-79.8) of them were non-Beijing registered residents. The urban and rural registered residents almost accounted for half of all the recruits. HIV positive rate was 4.6% (95% CI: 2.2-7.6) while 56.3% (95% CI: 50.9-62.5) of them reported having had bisexual sex preference. Only 14.8% (95% CI: 10.8-19.6) of them had ever had HIV test, while 22.8% (95% CI: 18.7-27.8) reported ever having had STDs. 55.3% (95% CI: 49.3-61.9) and 55.1% (95% CI: 48.7-61.3) of them had unprotected insert and receptive anal sex over the last 6 months.


CONCLUSIONS
Data from the HIV positive rate showed that there was a trend of increase among MSM in Beijing which called for urgent care to them.
