LIFT: Lifestyle Interventions For Two

This randomized, controlled trial is proposed to study the effect, in a cohort of racially and ethnically diverse group of overweight and obese pregnant women, of an Intensive Lifestyle Intervention (ILI) which utilize cognitive behavioral strategies to help participants achieve and maintain changes in dietary intake and physical activity habits compared to Usual Care (UC) on gestational weight gain (GWG), infant fatness, and mothers' post-delivery weight retention. The hypothesis is that the percent body fat at birth will be significantly less in offspring from ILI mothers than UC mothers.
