Does the use of peer support by video call, compared with standard care, increase exclusive breastfeeding rates and maternal breastfeeding self-efficacy scores during the first 6 months post partum?In this randomized clinical trial involving 442 first-time mothers, technology-based breastfeeding peer support did not increase the exclusive breastfeeding rate at 6 months, but it resulted in a significantly higher exclusive breastfeeding rate at 2 months and a significantly higher breastfeeding self-efficacy at 4 months compared with standard care.These findings suggest that integrating video call peer support into existing programs may improve maternal and infant outcomes by increasing breastfeeding rates and duration, as well as enhancing maternal confidence.
