Methods: Data were collected using a cross-sectional survey of YMSM (ages 18-24) in California using targeted advertising on popular GSN apps (n=761). Measures included current and past use of PrEP, demographic characteristics, sexual risk behaviors, and PrEP adherence. Current/past PrEP users were asked reasons for initiating PrEP. Those who discontinued PrEP were asked their reasons for stopping. Statistically significant correlates of PrEP uptake at the bivariate level were entered into multivariate logistic regression models predicting PrEP uptake. Reasons for initiation and discontinuation of PrEP use are reported descriptively.
Results: YMSM (Mean age=23; SD=3.2) were racially/ethnically diverse (white=21.7%; Black/African American=25.4%; Hispanic/Latino=31.9%; Other=21.0%) and primarily gay identified (81.9%). Less than one tenth were current or past PrEP users (9.7%). Those who made over $30,000/year (OR=4.13 ; CI : 1.87-9.12), reported unprotected condomless anal sex (OR : 3.41 ; CI : 1.71-6.78), had an HIV-positive sex partner (OR : 2.87 ; CI : 1.53-5.38), used poppers (amyl nitrate)(OR : 3.47 ; 1.96-6.13) and had a recent STI diagnosis (OR : 2.90 ; CI : 1.64-5.13) were more likely to use PrEP compared to those who did not. PrEP adherence among current users was high (92.5% reporting > 6-7 pills/week). Top reasons for discontinuation were related to fears about long-term side effects (33.3%), cost of the medication (28.6%), and cost of required medical visits (19.0%).
Conclusions and Implications: YMSM who use GSN apps are prime candidates for PrEP; however, uptake remains low. Concerns about cost may be addressed through insurance enrollment and pharmaceutical company-sponsored medication assistance programs; however, use of public funds for PrEP should be explored. GSN apps may be useful tools for information and PrEP screening. GSN app users who are also PrEP users may benefit from technology assisted adherence monitoring.
