Healthy4Baby: Preventing Postpartum Weight Retention Among Low-Income, Black Women

Black women are in particular need for obesity prevention and treatment. Targeting the
childbearing period has the potential to slow the accumulation of weight gain among this high
risk group. Previous interventions to prevent postpartum weight retention among Blacks are
sparse and limited by poor intervention adherence, high attrition, and failure to include
pregnancy in the study design. The proposed research aims to overcome these shortcomings by
developing an intervention that 1) focuses solely on Black women, 2) incorporates Black
mothers' information needs, values, and social context, 3) uses technology to facilitate
participant engagement, and 4) includes both the pregnancy and postpartum periods.
