Summary
This trial tests whether a mobile health program — combining a smartphone app, personalized text messages, and telephone coaching — can help overweight and obese women gain the recommended amount of weight during pregnancy. The program starts with low-intensity support and adds more help only for those who need it. Researchers will compare this approach to standard prenatal care and track weight gain, physical activity, and infant outcomes.
