Baseline and 24-month follow-up data were collected April–June 2016 and April–June 2018. At baseline, 1072 adolescent wives were interviewed (88% participation), with 90% retention at follow-up; 1080 husbands were interviewed (88% participation), with 72% retention at follow-up. Adolescent wives had higher likelihood of modern contraceptive use at follow-up relative to controls in Arm 1 (aIRR 3.65, 95% CI 1.41–8.78) and Arm 3 (aIRR 2.99, 95% CI 1.68–5.32); no Arm 2 effects were observed. Relative to those in the control arm, Arm 2 and Arm 3 participants were significantly less likely to report past year IPV (aIRR 0.40, 95% CI 0.18–0.88 for Arm 2; aIRR 0.46, 95% CI 0.21–1.01 for Arm 3). No Arm 1 effects were observed.
