Cognitive, psychosocial, and sociodemographic predictors of willingness to use HIV pre-exposure prophylaxis among Chinese men who have sex with men.

This study was designed to identify predictors of lower versus higher willingness to use pre-exposure prophylaxis (PrEP) to reduce HIV among men who have sex with men (MSM) in China. Participants were 570 MSM who completed self-report measures of willingness to use HIV PrEP, beliefs about HIV, psychosocial factors, sexual experiences and sociodemographic characteristics. Results of a hierarchical binary logistic regression analysis indicated that membership in a higher willingness group was predicted by previous consultation about HIV, more reported barriers to using condoms, and elevations in depressive symptoms. Independent of these factors, higher willingness to use HIV PrEP was predicted by beliefs that the intervention was low in stigma and high in potential benefits. In sum, the study highlighted the utility of broad-based assessment of demographic, behavioral, personality, and cognitive factors in identifying Chinese MSM who express willingness to use a promising biologically-based intervention to lower HIV risk.
