Preparing for a trial to test a postpartum weight retention intervention among low income women: feasibility of a protocol in a community-based organization

Abstract

Abstract Background Postpartum weight retention (PPWR) causes intergenerational harm, negatively affecting a mother’s cardiovascular health and ability to have future healthy pregnancies. Low-income minority women are at highest risk for PPWR with little guidance concerning timeline or strategy to lose weight after delivery. An academic-community partnership conducted observational and focus group work to develop an intervention for PPWR among low-income mothers. This study’s objective is to determine the feasibility of implementing a PPWR intervention trial in partnership with a community-based organization (CBO) serving low-income families with social service support. Methods We analyzed five implementation outcomes in this feasibility study: acceptability, adoption, appropriateness, penetration, and sustainability. Other secondary outcomes were the change in psychosocial and clinical outcomes from baseline to one year following the intervention delivery. Results An academic-community partnership developed and piloted a postpartum weight retention intervention among 17 participants that included 1) six weeks of interactive daily health texting, 2) exercise assistance with baby carrier, home exercise program, and pedometer provision, 3) two live healthy eating and baby feeding workshops, and 4) two 45-min home visits over one year to provide social support and acquire followup data. Implementation outcomes demonstrate an intervention supported by the organization and accepted by end-users, with increased capacity of the CBO to test and deliver an effective intervention. Weight loss was achieved by the majority of participants at one year (Md − 5 pounds (IQR = − 14.5 - 0.3). Conclusion We made protocol enhancements to the developed intervention based on the analysis of this study, and now prepare for a funded randomized controlled trial (RCT) in a community-based setting. Our central hypothesis is that low-income women who participate in a multi-component, low cost-intervention delivered by a CBO will have less postpartum weight retention than those women who do not participate in the program. Trial registration The trial was retrospectively registered, ID NCT02867631, 8/11/16.
