Individual and structural-level Correlates of Pre-exposure Prophylaxis (PrEP) lifetime and current use in a nationwide sample of young sexual and gender minorities.

Abstract

The objective of this analysis was to describe individual and structural-level factors associated with pre-exposure prophylaxis (PrEP) use among a sample of sexual and gender minorities (SGM) at risk for HIV recruited using limited interaction strategies. SGM (N = 3330), ages 15-34, without HIV enrolled in a nationwide limited interaction cohort study from 2017 to 2020. A baseline cross-sectional single-survey design examined individual and structural-level correlates of PrEP lifetime use and current use using logistic regression. PrEP lifetime use and current use were reported by 31.2% and 23.9%, respectively, of SGM with PrEP data (n = 3077). PrEP use outcomes (lifetime or current use) in cisgender MSM were associated with being over age 18, Black or other race, Hispanic/Latina/x/o ethnicity, being gay, being out to one's healthcare provider, having health insurance, being a college graduate, and having a greater number of PrEP peers. PrEP use outcomes (lifetime use or current use) in transgender/non-binary participants were associated with being over age 24, being Latinx, being transgender vs. non-binary, being assigned male at birth, being out to their healthcare provider, living in the western or northeastern United States, and having more peers on PrEP. More work is needed to address lower PrEP uptake in SGM under 18 and those whose sex risk may be more dynamic (e.g., non-binary, pansexual/queer, and bisexual SGM) and such strategies should consider utilizing peers to provide information and ameliorate structural barriers.
