Abstract

To assess the acceptability of pre-exposure prophylaxis (Pr-EP) among the female sex workers in Xinjiang.A volunteer-based, anonymous and one-to-one questionnaire survey was conducted in 762 female sex workers (FSW) in Urumqi and Kelamayi of Xinjiang Uyghur Autonomous Region.Among 762 FSW surveyed, 673 (88.32%) was not aware of pre-exposure prophylaxis with an awareness rate of 11.55%. The awareness rate of FSWs working in high-end entertainment venues was higher than that of FSWs working in medium-low end entertainment venues(P0.001). Five hundred and twenty eight FSWs (69.29%) were willing to take Pr-EP, 145 (19.03%) were unwilling to take the medicine and 89 (11.68%) were possible to use the Pr-EP. There was no significant difference in willingness of using Pr-EP among FSWs working in high and medium-low end entertainment venuew (P=0.285). The subjects who were willing to take Pr-EP mainly concerned of the drug security, effectiveness and cost. The main reasons for not willing to take Pr-EP were: not having risk of infecting HIV, suspecting effectiveness of Pr-EP and worrying about side effects.The acceptability to use Pr-EP in female sex workers of Xinjiang is relatively high and the drug security, effectiveness and cost will influence the promotion and application of Pr-EP in the future.

Abstract

Objectives We aimed to investigate the awareness of and willingness to use oral pre-exposure prophylaxis (PrEP) for HIV prevention among HIV-negative partners in HIV-serodiscordant heterosexual couples in Xinjiang, China and determine factors that predict willingness to use oral PrEP. Methods Between November 2009 and December 2010, a cross-sectional survey was carried out among 351 HIV-negative partners in HIV-serodiscordant heterosexual couples from three cities in Xinjiang, China. Participants completed a self-administered questionnaire to assess their awareness of and willingness to use oral PrEP. Additionally, blood samples were collected to test for HIV infection. Univariate and multivariate logistic regression analyses were performed to identify predictors of willingness to use oral PrEP. Results Only 10 participants (2.8%) reported having heard of PrEP, and only two reported ever using PrEP. However, 297 (84.6%) reported that they were willing to use oral PrEP if it was proven to be both safe and effective. Results of multivariate analysis revealed the following independent predictors of willingness to use oral PrEP: monthly household income (adjusted odds ratio = 2.78
