The study will test the effectiveness of a smartphone-based behavior modification program adapted for use in Women, Infants, and Children program in a state-wide, randomized controlled trial in 432 low-income women enrolled in the Louisiana Women, Infants, and Children program.


The study is a multi-site randomized controlled trial, testing the effectiveness of the smartphone-based behavior modification program in pregnant women within the Louisiana Women, Infants, and Children program. Equal number of participants will be randomized to either the intervention or the control. Although the intervention itself lasts 24 weeks (only during pregnancy), women will be enrolled in this study for approximately 18 months, from the 10-16th week of pregnancy until 12 month postpartum follow-up. Study outcomes will be assessed at three visits during pregnancy (early, mid, and late,) and three visits postpartum (1, 6, and 12 months).
