GROWell App Fails to Curb Pregnancy Weight Gain

Mobile health intervention does not significantly reduce excessive gestational weight gain or postpartum weight retention in randomized trial

Share

A randomized controlled trial assessed the effectiveness of the remote dietary intervention Goals for Reaching Optimal Wellness (GROWell) among 453 pregnant women in California. The study targeted women with a pre-pregnancy BMI of 25-42 kg/m², focusing on reducing excessive gestational weight gain (GWG) and postpartum weight retention (PPWR). The intervention, which provided personalized dietary goals via a mobile app, did not yield significant reductions in GWG or PPWR compared to a control group, although both groups showed lower rates than national averages. Future studies are recommended to explore enhancements to the program.
