Abstract

Daily oral preexposure prophylaxis (PrEP) for reducing HIV transmission is recommended for those at elevated risk, including sexual gender and minorities assigned male at birth (SGM-AMAB). Few studies have examined re-initiation among PrEP discontinuers, which is critical to ensuring optimization of PrEP’s protection. The current study examined predictors of re-initiation in a longitudinal sample of SGM-AMAB PrEP discontinuers (n = 253) from 10 waves of an ongoing cohort study (analytic n = 1,129). Multilevel structural equation models were used to examine the effects of psycho-social variables on re-initiation. In adjusted models, health insurance, and partner HIV positive status were significantly positively associated with PrEP re-initation. Being bisexual was significantly negatively associated with re-initiation relative to gay participants. Single status and open relationship agreements were associated with higher odds of re-initiation relative to monogamous relationships. Findings suggest that demographic, partnership characteristics and structural factors influence decisions to re-initiate PrEP after discontinuation.
