Prevalence and correlates of HIV and syphilis infections among men who have sex with men in Chongqing Municipality, China.

OBJECTIVE

To examine the prevalence and correlates of HIV/syphilis infections and sexually transmitted diseases (STDs) among men who have sex with men (MSM) in Chongqing, China.

METHOD: Cross-sectional surveys were conducted to provide information, including sociodemographics, sexual and drug use behaviors, HIV knowledge, and HIV-related services in 2006 and 2007, respectively. Multiple methods, including venue-based recruitment, community outreach, Internet advertisements, and peer referral, were used to identify men in Chongqing willing to participate in this study.

RESULTS

Of the 1692 participants, 10.8% were HIV-infected (range by district: 7.0%-15.0%), 8.6% were syphilis-infected, and 15.3% self-reported STD-related symptoms. HIV infection was associated with older age, recruitment from bathhouses/saunas, less education, more male sex partners, sex with a woman in the past 6 months, syphilis infection, and STD-related symptoms. Syphilis infection was associated with older age, less education, inconsistent condom use with a man, STD-related symptoms, and HIV infection. STD-related symptoms were associated with older age, being of nonlocal residency, inconsistent condom use with a humans, having ever paid for sex with a humans, HIV infection, and being from District 1.

CONCLUSIONS

HIV and syphilis infections have reached alarmingly high rates in Chongqing's MSM population. Better targeted, in-depth and comprehensive intervention strategies are needed urgently, including education, condom promotion and distribution, STD control, drug use-related intervention, and advocacy for HIV counseling and testing with bridges to HIV prevention and care services. Widespread testing for HIV, syphilis, and other major STDs in this risk group should be considered as measures for control.
