[Acceptability and influencing factors on pre-exposure prophylaxis programs among female sex workers in Guangxi, China].

Objective: To study the acceptability of pre-exposure prophylaxis (PrEP) program on prevention of human immunodeficiency virus (HIV) infection among female sex workers (FSWs) in Guangxi of China.

Methods: A cross-sectional survey using convenience sampling was administered among 405 FSWs in Nanning, Liuzhou and Beihai cities of Guangxi, China. Self-designed questionnaire, face to face interviews were used to collect HIV-related risk behaviors, knowledge and acceptability of PrEP.

Results: After an introduction on PrEP, presuming that it was effective, safe and free of charge, 85.9% of the 405 FSWs said they would use it. Data from logistic regression analysis showed that significant factors of intent to use PrEP would include the followings: workplace (OR = 2.256, P = 0.009), monthly income (OR = 0.257, P = 0.004), family closeness (OR = 0.338, P = 0.012), knowledge on HIV/AIDS (OR = 2.802, P = 0.028), HIV/AIDS risk was introduced from a strange client (OR = 0.363, P = 0.049), whether the gatekeeper ordering the use of condom (OR = 0.432, P = 0.010), whether consistent using condom with clients (OR = 3.010, P = 0.002), whether ever using drugs to prevent STD infection (OR = 3.570, P = 0.049) etc.

Conclusion: Awareness on HIV/AIDS knowledge and self-protection seemed the main influential factors while health education might promote the acceptability of PrEP.
