Objectives. To evaluate whether text-messaging programs can improve reproductive health among adolescent girls in low- and middle-income countries. Methods. We conducted a cluster-randomized controlled trial among 756 female students aged 14 to 24 years in Accra, Ghana, in 2014. We randomized 38 schools to unidirectional intervention (n = 12), interactive intervention (n = 12), and control (n = 14). The unidirectional intervention sent participants text messages with reproductive health information. The interactive intervention engaged adolescents in text-messaging reproductive health quizzes. The primary study outcome was reproductive health knowledge at 3 and 15 months. Additional outcomes included self-reported pregnancy and sexual behavior. Analysis was by intent-to-treat. Results. Frombaseline to 3months, the unidirectional intervention increased knowledge by 11 percentage points (95% confidence interval [CI]= 7, 15) and the interactive intervention by 24 percentage points (95% CI = 19, 28), from a control baseline of 26%. Although we found n ochanges in reproductive health out comes overall, both unidirectional (odds ratio [OR] = 0.14; 95% CI = 0.03, 0.71) and interactive interventions (OR= 0.15; 95% CI = 0.03, 0.86) lowered odds of self-reported pregnancy for sexually active participants. Conclusions. Text-messaging programs can lead to large improvements in reproductive health knowledge and have the potential to lower pregnancy risk for sexually active adolescent girls.
