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. 056 UR259
