Impact of the Rochester LARC Initiative on adolescents’ utilization of long-acting reversible contraception

Abstract

Preventing unintended teen pregnancy is a national public health priority, and increasing access to long-acting reversible contraception is part of the recommended strategy for the achievement of this goal. Nevertheless, adolescent long-acting reversible contraceptive use across the nation has remained low, even after national and state-level programs increased coverage for no-cost contraception. One persistent barrier is misinformation about the safety, efficacy, and availability of long-acting reversible contraception for teens. To overcome this barrier, the Hoekelman Center, in collaboration with multiple partners, designed and implemented a community health intervention. The Greater Rochester LARC Initiative disseminated accurate information about contraceptive options with a focus on long-acting reversible methods by delivering interactive lunch-and-learn talks throughout the Greater Rochester, NY area. Audiences included both healthcare providers and adults who work with adolescents in nonmedical community-based organizations. The primary purpose of this study was to evaluate the community-level impact of the Greater Rochester LARC Initiative on adolescent long-acting reversible contraception use. Our evaluation design was pre-post with a nonrandomized control group. We used publicly available Youth Risk Behavior Surveillance System data from the years 2013, 2015, and 2017 for our intervention site of Rochester, NY, New York City, New York State, and the United States overall. These years cover the time before and after the intervention began in 2014. We used z-statistics in investigating the hypothesis that long-acting reversible contraception use increased more in Rochester than in the comparison populations. Between 2013 and 2017, long-acting reversible contraception use in Rochester rose from 4-24% of sexually active female high school students (P<.0001). Over the same period, long-acting reversible contraception use in New York State rose from 1.5-4.8%, and in New York City long-acting reversible contraception use rose from 2.7-5.3%. In the United States overall, long-acting reversible contraception use rose from 1.8-5.3%. Thus, the increase in long-acting reversible contraception use in Rochester was larger than the secular trend in the control groups (P<.0001). Adolescent long-acting reversible contraceptive use increased significantly more in Rochester than in the nation as a whole. This finding is consistent with a substantial positive impact of the Greater Rochester LARC Initiative, which implies that similar interventions could be useful complements to unintended teen pregnancy prevention programs elsewhere and might be helpful more generally for the diffusion of evidence-based health-improvement practices.
