HIV testing and sexual risks among migrant men who have sex with men: findings from a large cross-sectional study in Beijing, China.

Despite the exacerbating HIV transmission among migrant men who have sex with men (MSM) in China, few epidemiological studies explore their HIV testing/risk profiles. We sought to explore sociodemographic/behavioral correlates of HIV/syphilis and HIV testing among migrant MSM. A study was conducted among 3,588 HIV-uninfected MSM. Participants were recruited via short message services, peer referral, web-advertisement and community outreach. HIV/syphilis infections were lab-confirmed. Migrant MSM were more likely to be HIV-infected compared to local MSM. Among 2,699 migrant MSM, HIV testing was associated with older age, living longer in Beijing, having 10 lifetime male sexual partners (LMSPs), having insertive anal sex; while being unemployed/retired and having condomless receptive anal sex (CRAS) were associated with a lower odds of HIV testing. Being married, living longer in Beijing, ever testing for HIV and having sex with women were associated with lower HIV odds; while being unemployed/retired, having higher HIV perception, having 10 LMSPs and having CRAS were associated a higher HIV odds. Increased likelihood of syphilis was associated with older age, being employed, higher HIV perception, having 10 LMSPs and having CRAS. Our study provides implications for targeted interventions to tackle HIV/STI risks and improve HIV testing among migrant Chinese MSM.
