Efficacy of an mHealth‐delivered behavioral intervention on weight loss and cardiometabolic risk in African American postpartum people with overweight or obesity: the SnapBack randomized controlled trial

Among African American postpartum people enrolled in WIC, an mHealth-delivered intervention reduced systolic BP but not additional cardiometabolic risk factors or weight. Intervention participants with high engagement had significantly better postpartum weight outcomes, and thus, next steps include addressing barriers to engagement.
