Syphilis Diagnosis and Interest in Doxycycline Postexposure Prophylaxis Among Young Black Sexual and Gender Minorities

Background: Doxycycline postexposure prophylaxis (doxy-PEP) is a low-cost, effective strategy for preventing syphilis and other bacterial sexually transmitted infections among men who have sex with men and transgender women, yet doxy-PEP remains underused by young black sexual and gender minorities (YBSGM). This analysis examined sociodemographic, sexual health, and substance use factors associated with interest in doxy-PEP among a human immunodeficiency virus (HIV) status-neutral cohort of YBSGM. Methods: The Neighborhoods and Networks Phase 2 (N2P2) cohort included YBSGM, and our primary outcome was interest in doxy-PEP. Generalized linear models were fit to calculate the unadjusted and adjusted relative risks (RRs) between interest in doxy-PEP and sociodemographic and health factors. Results: = .02) remained associated with interest in doxy-PEP. Conclusions: YBSGM who were interested in doxy-PEP were more likely to have had a syphilis diagnosis and participate in group sex. YBSGM with these risk factors represent an important demographic for the scale-up of doxy-PEP use.
