We aimed to identify and describe the sexual behaviors of MSM most at risk of HIV infection in West Africa. HIV-negative MSM were provided a quarterly preventive follow-up package in the community-based cohort CohMSM. They completed face-to-face sociobehavioral questionnaires every 6 months. This sub-study on 520 participants used a baseline, 6-, 12- and 18-month data cluster analysis to categorize two profiles (high risk [HRE] and moderate risk [MRE] of exposure to HIV) based on three risky sexual practices over the previous 6 months. HRE-MSM (61%) were more engaged in receptive practices, had a higher proportion of inconsistent condom use during anal sex, and reported more sexual partners than MRE-MSM (39%). The proportion of HIV seroconversions observed during the first 18 months of follow-up using sexual behavioral profiles (92% are HRE-MSM) was higher than using the three risky sexual practices separately. Factors associated with the HRE-MSM profile were being younger (18-21 years), reporting stigma, and having had no female partner while being attracted only to men. Our findings suggest that in order to identify MSM most at risk of HIV infection, several risky sexual practices need to be evaluated in a combined approach. Prevention programs should pay particular attention to younger MSM, and implement activities addressing questions of MSM identity and stigma in order to reduce the dynamic of HIV infection in Western African MSM. specialized MSM HIV risk Sexual behavior Identity West Africa Sexual orientation MALI COTE D'IVOIRE BURKINA FASO TOGO BAMAKO ABIDJAN OUAGADOUGOU LOME 052 056 49 1 331-345 2020 0004-0002 https://www.documentation.ird.fr/hor/fdi:010077916 10.1007/s10508-019-01513-z 0004-0002 [F B010077916] https://www.documentation.ird.fr/hor/fdi:010077916 https://www.documentation.ird.fr/intranet/publi/2020/03/010077916.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2020-05-18 2025-02-24 fdi:010077916 fre
