What is a common risk factor for STIs identified by the USPSTF?

Inconsistent condom use is recognized as a significant risk factor for sexually transmitted infections (STIs) by the USPSTF. This is because condoms are a primary method of reducing the transmission of STIs during sexual activity. When individuals do not consistently use condoms, they increase their risk of exposure to infections, especially if they engage in sexual activities with multiple partners or if their partner's STI status is unknown.

In contrast, having a long-term partner and being married could imply a lower risk for STIs, assuming mutual monogamy and mutual testing. Regular STI screenings are preventive measures that help identify and treat infections early but do not in themselves constitute a risk factor; instead, they are part of a proactive health strategy. Therefore, inconsistent condom use stands out as a direct behavior that increases susceptibility to STIs.
