SAFER-PrEP investigates the long-term impact of Pre-Exposure Prophylaxis (PrEP) on risky sexual behaviors and Sexually Transmitted Infection (STI) prevalence among users in Aquitaine. The study aims to compare STI rates over the last three months between individuals on PrEP for over a year and those on PrEP for less than a year.

Amidst the increasing adoption of PrEP for HIV prevention, concerns arise regarding potential behavioral shifts and heightened risks for Sexually Transmitted Infections (STIs). The comprehensive investigation into these phenomena seeks to provide nuanced insights into the long-term implications of PrEP, contributing valuable data to public health initiatives and refining prevention strategies in the face of evolving sexual health landscapes.

Procedure: Participants, comprising individuals on PrEP for over a year and those for less than a year, will be engaged through a observational approach.
