%X <B>OBJECTIVE: </B>Contraceptive method type matters to sexually transmitted infection (STI) prevention, but contraceptive counseling often emphasizes method efficacy and the benefits of "forgettable" methods, including long-acting reversible contraceptives (LARCs). We aimed to explore associations between prescription method type and annual STI testing and investigated whether these associations relate to annual well-woman visits.<BR><B>METHODS: </B>We constructed a panel of 20,949 young women (<25) enrolled in Delaware's Medicaid program from 2012 through 2019. Conditional logit regressions measured associations between contraceptive method type and annual testing for gonorrhea, chlamydia, or syphilis. We stratified contraceptive methods into LARC, short-acting reversible methods (SARC; pills, patch, ring, and injectable), or no prescription method. We estimated three models examining STI testing in year of method initiation, in years afterwards, and attendance to a well-woman visit as a potential mediator of these associations.<BR><B>RESULTS: </B>STI testing rates did not differ between LARC versus SARC users in the year of method initiation. In the two years after method initiation, LARC versus SARC users were less likely to be tested (OR = 0.73 to OR = 0.87) and less likely to have a well-woman visit (OR = 0.65 to OR = 0.79). In models controlling for attendance to well-woman visits, the decreased likelihood of STI testing in years after initiating LARC versus SARC is largely eliminated, indicating that well-woman visits mediate the relationship between method type and STI testing.<BR><B>CONCLUSIONS: </B>LARC use relates to reduced STI testing in years after method initiation due to reduced attendance to well-women visits. These findings can inform clinical practice and STI prevention.
