Effectiveness of male partner-targeted breastfeeding education and support interventions on mothers' breastfeeding self-efficacy in central Ethiopia: a cluster-randomized controlled trial.

The purpose of this study was to evaluate the effect of male partners' targeted antenatal and postnatal breastfeeding education and support interventions on maternal breastfeeding self-efficacy in central Ethiopia. A two-arm parallel group cluster randomized controlled trial was carried out among couples in a community setting in the Hadiya Zone, central Ethiopia. A total of 408 couples from 16 clusters were randomly assigned to either the intervention (n = 204) or control group (n = 204). The analysis was conducted using an intention-to-treat approach. A generalized estimating equation (GEE) analysis was done to evaluate the effectiveness of the interventions. Maternal BFSE was significantly higher among mothers whose male partner received breastfeeding education and support interventions than those who did not receive the interventions (130 (65.0%) v 90 (45.9%), P < 0.001). The net effect of the intervention on improving maternal BFSE was 20.9% [95% CI: 16.9%-24.9%]. In the GEE model, maternal BFSE was 48% [RR = 1.48, 95% CI: 1.23, 1.79] higher in the intervention group than the control group. Involving male partners in breastfeeding promotion activities can enhance the mother's self-efficacy and confidence in breastfeeding.Trial registration: ClinicalTrials.gov identifier (NCT number), NCT05173454.
