Abstract:
OBJECTIVETo investigate incidence of HIV infection and identify associated risk factors among men who have sex with men (MSM) in common bathing pools in Tianjin.
METHODSA prospective cohort study was conducted among the MSM recruited in a common bathing pool in Tianjin from 2011 to 2013. A total of 733 MSM were surveyed to obtain the information about their sociodemographic characteristics, HIV-related knowledge awareness and sexual behaviors, and subsequent follow-up surveys were carried out every four months. Cox regression analysis was conducted to identify the risk factors for HIV infection.
RESULTSA total of 59 HIV infection cases were found in the 2.5-years follow-up survey. The cumulative follow-up time was 7384.9 person-months. The incidence rate of HIV infection was 9.59/100 person-year. The multivariate Cox regression analysis showed that young age, low score of HIV/AIDS knowledge awareness (HR=1.82, 95%CI:1.03-2.66), having two and more sexual partners during past 6 months (HR=1.74, 95%CI: 1.26-2.58) and syphilis (HR=2.36, 95%CI:1.31-3.27) were significantly associated with HIV infection in this MSM cohort.
CONCLUSIONSLow score of HIV/AIDS knowledge awareness, young age, having two and more sexual partners during past 6 months and syphilis were the risk factors for HIV infection in MSM in common bathing pools. It is necessary to strengthen the HIV surveillance and intervention in this population.
