Summary

This study tested a smartphone app called SmartMoms in 351 low-income pregnant women enrolled in the Louisiana WIC program. The app helped women track their weight and activity, gave personalized tips, and connected them with counselors to encourage healthy weight gain during pregnancy. The goal was to see if the app could help more women gain the right amount of weight as recommended by experts.

What this could lead to

What could go wrong
This is a completed trial, but the intervention is behavioral and results may vary by individual. It may not work for everyone, and long-term benefits are not yet proven.
