[Acceptability and influencing factors of pre-exposure prophylaxis among men who have sex with men in Guangxi].

Published: August 1, 2011


To study the acceptability of pre-exposure prophylaxis (PrEP) to prevent the transmission of HIV among men who have sex with men (MSM) in Guangxi, China.

Snow-balling methods were used to recruit 650 MSM in Guangxi. Questionnaires and interview were administrated to these 650 men, using a self-designed questionnaire and face to face interviews to collect information on HIV-related risk behaviors, knowledge and acceptability of PrEP.

After an introduction on PrEP by interviewers, followed by as the statement-‘If PrEP was effective, safe and free of charge’, 597 (91.9%) of the 650 MSM claimed that they would accept it, with the main reason as the recognition of ‘PrEP can decrease the risk of HIV infection’. For those who refused to use it, most of them said that were afraid of the side-effect and doubted on the effectiveness of PrEP. Data from logistic regression analysis showed that those who had found partners through friends (OR = 6.21, P = 0.020) and those who would advise his friend to use PrEP (OR = 39.32, P = 0.000) were more likely to accept PrEP. Those who thought they could protect themselves from HIV infection (OR = 0.32, P = 0.010) or not having sex with the ones who refused to use a condom (OR = 0.34, P = 0.010) were less likely to accept PrEP.

Effectiveness, safety and cost seemed to be the main influential factors related to the acceptability of PrEP. Peer education might improve the acceptability of PrEP.
