Sustained impact of community‐based interventions on contraceptive use among married adolescent girls in rural Niger: Results from a cluster randomized controlled trial

Objective To evaluate the sustained impact of community‐based family planning (FP) interventions on current modern contraceptive and long‐acting reversible contraceptive (LARC) use among married adolescent girls in rural Niger. Methods We used a cluster randomized controlled trial design following married adolescent girls and their husbands over 3 years. Villages were randomized to one of four arms: household visits, small group discussions, combined intervention, or control. For 1.5 years, couples were exposed to one intervention activity per month and 1.5 years after implementation ended, we used a multi‐level mixed effects logistic regression model to evaluate changes in key FP outcomes. Results We analyzed survey data from 404 married adolescent girls with data at baseline and endline. Small group discussions (+35.6%; adjusted odds ratio [aOR] 7.94, P
