Abstract

Background: Unprotected anal intercourse (UAI) remains the main risk factor for HIV among men who have sex with men (MSM), but risk varies by the sexual position adopted and the risk reduction strategies used. Here, we report on sexual position, and knowledge of partners' HIV status, during UAI to assess whether MSM in Scotland are using sexual risk reduction strategies.

Methods: Anonymous, self-complete questionnaires and Orasure oral fluid specimens (OraSure Technologies, Inc., Bethlehem, Pennsylvania, USA) were provided by 1277 MSM in commercial gay venues in Glasgow and Edinburgh, Scotland, United Kingdom (59.7% response rate). Overall, 488 MSM (39.7%) reported any UAI in the past 12 months; 318 reported on partner HIV status and sexual position and are included in these analyses.

Results: Being equally either the insertive or receptive partner during UAI was most commonly reported; 23.1% of HIV-negative MSM reported exclusive insertive UAI, whereas no MSM with diagnosed HIV reported exclusive receptive UAI. Five diagnosed HIV-positive MSM reported always knowing their partners' HIV status and only having HIV-positive partners (50.0% of HIV-positive MSM reporting UAI; 11.9% of the diagnosed HIV-positive sample); 160 HIV-negative MSM reported having had an HIV test (and therefore being aware of their HIV-negative status), always knowing their partners' status, and only having HIV-negative partners (52.8% of HIV-negative MSM reporting UAI; 13.7% of the total HIV-negative sample).

Conclusions: Behavior suggestive of serosorting and strategic positioning (among HIV-negative MSM) was evident in this sample, but inconsistent adoption of these and general versatility in sexual behavior suggest that they have a limited role.
