HIV testing and sexual risks among migrant men who have sex with men: findings from a large cross-sectional study in Beijing, China
Liu Y , Vermund SH , Ruan Y , Liu H , Zhang C , Yin L , Shao Y , Qian HZ . AIDS Care 2017 30 (1) 1-9 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. |
Substance use and HIV-risk behaviors among HIV-positive men who have sex with men in China: repeated measures in a cohort study design
Zhang C , Liu Y , Sun X , Wang J , Lu HY , He X , Zhang H , Ruan YH , Shao Y , Vermund SH , Qian HZ . AIDS Care 2016 29 (5) 1-10 Global literature revealed that seropositive men who have sex with men (MSM) posed an even higher risk compared to their seronegative counterparts. Identifying risk factors that contribute to HIV-risk behaviors will help to curb the rapid HIV transmission among this group. Our hypothesis was that MSM with substance use were more likely to conduct HIV-risk behaviors, even after accounting for repeated measures. In the current study, we employed a cohort study design by following a group of 367 HIV-positive MSM up to four visits for one year to collect information regarding their sexual behaviors and history of substance use in the past three months. We used Generalized Estimating Equations (GEE) models to account both within- and between-subject variation when assessing associations between substance use and HIV-risk behaviors. A total of 367 MSM were included at the baseline with a mean age of 29.6 years. After accounting for potential confounders and time-varying effects, our models indicated that drug and alcohol use increase HIV risks at the population level by increasing risks of drinking alcohol before sex, having unprotected sex with men and seropositive partners, having more lifetime female sex partners and having a higher number of male sexual partners in the past three months. The current study is one of the first studies with repeated measures to evaluate the association between substance use and sexual risk behaviors among MSM in China. Findings in the current study have several implications for future research. We call for more rigorous study design for future research to better capture changes of risky behaviors among this at-risk population. |
