Brief summary
The investigators will test the efficacy of a tailored behavioral lifestyle modification program to support cardiovascular health in postpartum women with excessive gestational weight gain. This program will include a mobile health texting component postpartum to support changes in nutrition and physical activity. The investigators will randomize women into either the control arm (usual care) or the intervention (usual care + mobile health program postpartum). The women will be recruited during their 3rd trimester once they have been identified as gaining too much weight according to the 2009 IOM guidelines during pregnancy.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| BMI (body mass index) | 4 months postpartum | A mobile Health intervention tailored for the 30 postpartum mother and grounded in behavioral change theory will be associated with significantly more reduction in BMI than 30 women not enrolled in the intervention. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Cardiovascular health metrics | 4 months postpartum | (1) Examine changes in cardiovascular health metrics (fasting glucose, fasting insulin, and BP) and markers of inflammation (hs-CRP) verses control group (2) We will evaluate changes in perceived nutrition, physical activity, and weight-loss self-efficacy; self-efficacy has been shown to be a direct predictor of behavior (3) measure the effects of breastfeeding support on the length of time a mother breastfeeds verse the control group. |
| Change in self efficacy score based on behavioral self-efficacy scale | 4 months postpartum | We will measure changes in pre- and post-intervention self-efficacy of all women in intervention and control arms. |
| Cardiovascular health metric | 4 months postpartum | Measure the effects of breastfeeding support on the length of time a mother breastfeeds verse the control group. |
