Key Points Question Is access to HIV preexposure prophylaxis (PrEP) associated with the trajectory of preexisting trends in sexually transmitted infections (STIs) among high-risk men who have sex with men (MSM)? Findings In a before-after cohort study of high-risk MSM participating in a population-based PrEP implementation project, STI positivity was high while men were taking PrEP with no increasing trend in quarterly STI positivity, compared with similar high positivity before PrEP but an increase of 8% per quarter. Meaning These findings suggest that studies that do not consider preexisting STI trends may overestimate the association of PrEP with STI incidence.
