Applying the Behavioral Model for Vulnerable Populations to Pre-Exposure Prophylaxis Initiation Among Women Who Inject Drugs.

This study used Behavioral Model for Vulnerable Populations (BMVP) to identify factors associated with pre-exposure prophylaxis (PrEP) initiation among women who inject drugs (WWID) when PrEP was offered at a syringe services program (SSP). Participants (n = 89) were WWID, $ge18 years, and eligible for PrEP. Most (69) initiated PrEP. Chi square and t tests were used to identify bivariate relationships between BMVP factors and PrEP initiation. A greater proportion of PrEP initiators (compared to non-initiators) reported sexual assault, frequent SSP attendance, earning $ge$5,000 annually and inconsistent condom use. Findings can inform the development of gender-specific strategies to promote PrEP among WWID.
