Abstract

The HIV infection rate in China among men who have sex with men (MSM) is high due to the high prevalence of high-risk sexual behaviors. This study aims to explore the association of high-risk sexual behaviors and the prevalence of HIV and syphilis among MSM with different sexual roles in Changsha, China. A convenience sample of 601 MSM who came to a gay organization for voluntary counseling and testing completed a pencil-and-paper survey from April to December, 2014. At the same time they also accepted HIV and syphilis testing. Results showed that 27.3% (164/601) of the participants self-identified as “top”, 15.3% (92/601) as “bottom”, and 57.4% (345/601) as “versatile”. The overall prevalence were13.3% (80/601) for HIV and 7.3% (44/601) for syphilis. HIV prevalence was significantly greater for MSM identified as bottom (16.3%, 15/92), and versatile (15.9%, 55/345) than top (6.1%, 10/164). Prevalence for syphilis infection was not significantly different among different roles. Multivariate analyses indicated that MSM who were married (OR = 2.125, 95% CI 1.004~4.500), with a receptive role (OR = 5.289, 95% CI 1.821~15.362) and a dual role (OR=3.551, 95% CI 1.371~9.200), had no oral sex in recent 6 months (OR=0.065, 95% CI 0.010~0.420), didn’t have sex with woman in recent 6 months (OR=0.218, 95% CI 0.058~0.817) were more likely to be HIV positive. MSM of different sexual roles had different characteristics of high-risk sexual behaviors and different HIV infection rates. Targeted interventions should consider their characteristics of the sexual roles in future.
