Despite declines in recent decades, the United States still has one of the highest teen birth rates among industrialized nations.[1] The United States also has important disparities in teen birth rates by race/ethnicity: For example, Latinx teens have higher birth rates than the national average.[2] To address these disparities, schools and communities with a large percentage of Latinx youth require teen pregnancy prevention programs that are tailored for, and effective with, this population. One promising approach is to incorporate peer educators (educators of similar age and background as the program’s target youth) into teen pregnancy prevention programming; this may be effective with a variety of adolescent populations.[3],[4],[5],[6] Reproductive health messages from peers may be more meaningful to youth, and adolescents may be more likely to approach their peers than adults with sensitive questions.[7],[8]

From 2015 to 2020, Child Trends conducted a randomized controlled trial to evaluate the impact of Re:MIX on early sex, unprotected sex, and key mediators. Re:MIX, developed by EngenderHealth, is a comprehensive, in-school teen pregnancy prevention program targeting youth ages 13 to 17. The program is co-facilitated by a professional health educator and a young parent educator, and was piloted in schools with a high percentage of Latinx students. Findings from this random assignment evaluation, recently published in the Journal of School Health (JOSH), expand research on peer education approaches and highlight the feasibility and promise of this method with Latinx students. This research brief summarizes the results from the JOSH article.
