Abstract

We systematically reviewed and meta-analyzed global data on the relative risk for HIV infection among men who have sex with men (MSM) engaging in different roles in anal sex. MSM engaging in receptive anal sex only (MRAI) and MSM engaging in both insertive and receptive anal sex (MIRAI) were 6.9 (95 % CI 5.5-8.6) and 4.3 (95 % CI 3.6-5.3) times more likely to have prevalent HIV compared to MSM engaging in insertive anal sex only (MIAI) in 1981-1985. These figures were 1.8 (95 % CI 1.6-2.0) and 2.2 (95 % CI 2.0-2.4) in 1986-2010. Overall, MRAI and MIRAI were 6.2 (95 % CI 3.3-11.8) and 6.6 (95 % CI 3.8-11.7) times more likely to develop incident HIV infection compared to MIAI. MRAI are at higher risk for HIV infection compared to MIAI. HIV prevalence among men engaging in all roles in anal sex is high enough that all MSM should be aware of potential risk.
