Correlates of PrEP Cascade Outcomes Among Immigrant Latino Men Who Have Sex with Men

HIV disparities among U.S. Latino men who have sex with men (LMSM) persist alongside lower PrEP use. We examined correlates of PrEP cascade outcomes among 287 cisgender immigrant LMSM. PrEP conspiracy beliefs were negatively associated with HIV testing (OR = 0.77, 95% CI: 0.59–0.99, p=.04); knowing a PrEP user was positively associated (OR = 3.09, CI: 1.81–5.28, p<.0001). PrEP readiness was associated with positive PrEP attitudes (belief: OR = 2.23, CI: 1.51–3.30, p<.0001; plan: OR = 1.86, CI: 1.13–3.06, p=.02), multiple sexual partners (belief: OR = 2.06, CI: 1.02–4.16, p=.04; plan: OR = 2.25, CI: 1.04–4.87, p=.04), knowing a PrEP user (belief: OR = 4.18, CI: 2.10–8.32, p<.0001; plan: OR = 3.78, CI: 1.43–10.03, p=.008), and internalized sexual orientation stigma (plan: OR = 1.78, CI: 1.11–2.85, p=.02). Positive PrEP attitudes (OR = 1.59, CI: 1.17–2.18, p=.004) and lower barriers (OR = 0.70, CI: 0.52–0.95, p=.02) were associated with increased PrEP use, and medical mistrust (OR = 2.95, CI: 1.32–6.58, p=.008) with nonadherence.
