“…This study also identified significant associations between the number of male sex partners, the HIV serological status of male sex partners, recreational drug use, HSV-2 infection status, and the willingness to take LAI-PrEP among MSM with oral PrEP experience. Previous studies reported on factors associated with MSM’ willingness to take LAI-PrEP or the preference for LAI-PrEP, including demographic (e.g., age [ 22 , 31 , 35 ], ethnicity [ 23 , 33 , 35 , 39 ], educational level [ 21 , 27 , 34 ], income [ 22 ], and insurance [ 39 ]), behavioural (e.g., sex roles [ 20 , 31 ], number of male sexual partners [ 34 , 35 ], HIV serological status of male sex partners [ 21 ], condom use [ 19 ], and HIV testing [ 20 ]), HIV risk perception-related [ 21 , 27 ], and PrEP-related factors (e.g., PrEP use experience [ 22 , 27 , 33 , 35 ]). The factors, such as demographic characteristics and HIV-related behaviours, in this study were similar to those in previous studies.…”
