Awareness, knowledge, use, willingness to use and need of Pre-Exposure Prophylaxis (PrEP) during World Gay Pride 2017.

Objective: To assess the awareness, knowledge, use, and willingness to use and need of PrEP among men who have sex with men (MSM) and transgender women (TW) who attended World Gay Pride (WGP) 2017 in Madrid.

Design And Methods: Online survey. Participants were recruited through gay-oriented dating apps and HIV Non-Governmental Organizations´ social media. Inclusion criteria included being MSM or TW, age 18 years old or above, and having attended WGP in Madrid. Information regarding the participant's awareness and knowledge, use or willingness to use, and need for PrEP was collected, as well as sociodemographic characteristics. Participants were considered to be in need of PrEP if they met one of the following indication criteria: having practiced unprotected anal intercourse with more than 2 partners, having practiced chemsex, or having engaged in commercial sex-all in the preceding 6 months. Descriptive and multivariable analyses with logistic regression were conducted.

Results: 472 participants met the inclusion criteria and completed the questionnaire. The mean age was 38, 97.7% were MSM, 77% had a university education, and 85% were living in Spain, mostly in big cities. Overall, 64% of participants were aware of PrEP, but only 33% knew correctly what PrEP was. 67% of HIV-negative participants were willing to take PrEP, although only 5% were taking it during WGP, mostly due to lack of access. 43% of HIV-negative respondents met at least one PrEP indication criteria. For HIV-negative men living in Spain, university education and living in big cities was associated with PrEP awareness. Lower education level and meeting PrEP criteria was associated with willingness to use PrEP.

Conclusions: Our study shows that among MSM attending WGP 2017 in Madrid, there was limited PrEP awareness, low accuracy of PrEP knowledge, and a high need and willingness to use PrEP. Health authorities should strengthen existing preventive strategies and implement PrEP.
