This study investigated the evolution of HIV risk perception on pre-exposure prophylaxis adherence and condom use in men who have sex with men at high risk of HIV and associated factors. Group-based trajectory modelling helped in identifying patterns of risk perception, pre-exposure prophylaxis adherence and condom use over time. The association between the former and the latter two dimensions was then investigated. An estimated 61 per cent (p < 0.001) of participants perceiving low risk and 100 per cent (p < 0.001) of those perceiving high risk had systematic pre-exposure prophylaxis adherence, while an estimated 49 per cent (p < 0.001) and 99.8 per cent (p < 0.001), respectively, reported low-level condom use. specialized condom use HIV men who have sex with men pre-exposure prophylaxis adherence risk perception trajectories FRANCE CANADA 056 26 10 1575-1586 2021 1359-1053 https://www.documentation.ird.fr/hor/fdi:010077157 10.1177/1359105319883927 1359-1053 [F B010077157] https://www.documentation.ird.fr/hor/fdi:010077157 https://www.documentation.ird.fr/intranet/publi/2019/11/010077157.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2019-12-12 2025-02-24 fdi:010077157 fre
