Abstract

Although the HIV epidemic is generalized in West Africa, some population groups such as men who have sex with men (MSM), especially those engaged in transactional sex (TS), are thought to be particularly more vulnerable to HIV than others. However, few data are available to help identify their health-related needs with a view to implementing targeted prevention interventions. To fill this knowledge gap, we aimed to characterize MSM reporting TS (MSM-TS) and to identify factors associated with their sexual practices using data from the prospective cohort study CohMSM, which was conducted in Burkina Faso, Côte d'Ivoire, Mali and Togo. Three stigmatization sub-scores were constructed (experienced, perceived and internalized). The generalized estimating equation method was used for data analysis. Of the total 630 HIV-negative MSM recruited in CohMSM, 463, 410 and 244 had a follow-up visit at 6, 12 and 18 months, respectively. In a total of 1747 follow-up visits, 478 TS encounters were reported by 289 MSM-TS (45.9%). Of the latter, 91 regularly reported TS (31.5%), 55 (19.0%) stopped reporting TS after baseline, and 53 (18.3%) reported TS after baseline and 90 (31.1%) occasionally reported TS. The following variables, regarding the previous 6 months, were positively associated with TS: being younger (aOR[95%CI]:1.86[1.39-2.50]), less educated (aOR[95%CI]:1.49[1.09-2.03]), unmarried status (aOR[95%CI]:1.79[1.10-2.93]), satisfaction with current sex life (aOR[95%CI]:1.41[1.06-1.88]), group sex with men (aOR[95%CI]:2.07[1.46-2.94]), multiple male sexual partners (aOR[95%CI]:1.85[1.40-2.44]), receptive or versatile anal sex with male partners (aOR [95%CI]:1.48[1.12-1.96]), giving benefits in exchange for sex with a man (aOR[95%CI]:2.80[1.97-3.98]), alcohol consumption (aOR[95%CI]:1.44[1.08-1.93]) and drug use (aOR[95%CI]:1.82[1.24-2.68]) during sex, and finally experiencing stigmatization (aOR [95%CI]:1.15[1.07-1.25]). Condom use during anal sex (aOR[95%CI]:0.73[0.53-0.99]) was negatively associated with TS.
