Overview
The goal of this clinical trial is to better understand how different strategies, timing, and enhancements to medically tailored food delivery will address structural inequities in the food environment, empower communities to sustain behavior change, and ultimately improve postpartum weight control to prevent type 2 diabetes-a potent contributor to disparate mortality among Black women.
The main aims of the study are:
- To conduct a pilot randomized control trial to test the feasibility, acceptability, and effectiveness of a multi-component Medically Tailored Food (MTF) intervention, Moveable Feast ENHANCED (a hybrid MTF intervention with a patient-activated change from prepared meals to fresh food delivery, customized for postpartum people, culturally customized for engagement and adherence, and food provision for dependents) versus MFeast Usual Care (prepared medically tailored foods only)
- To test sustainability and scalability.
Participants will:
- Respond to online surveys (supported by study team members via scheduled phone calls) via REDCap links shared before each study visit at baseline, 3, 6 months post-delivery after the baseline survey.
- Submit anthropometric data (i.e, weight) and information about laboratory results ( e.g. HgbA1C)
Description
This study will evaluate the feasibility, acceptability, and preliminary effectiveness of a postpartum dietary intervention for Black women with obesity and a recent pregnancy complicated by gestational diabetes mellitus (GDM). The investigators will recruit women through Medicaid insurance plans (Priority Partners), clinical obstetric practice (Johns Hopkins Outpatient Center, Women's Health Center), perinatal community-based organizations (MOM Cares and Bloom Collective), and home-visiting locations (The Family Tree of Maryland)-all of which can verify clinical outcomes for participants.
At 37 weeks gestation, participants are contacted by the study team for consent, baseline data collection (baseline visit 1), and randomization 1:1 to receive the intervention vs. usual care (which begins in the first postpartum week). 3-7 days after randomization, the remainder of baseline visit information (baseline visit 2) is collected including information for the prepared MTF vendor (Moveable Feast Baltimore)
The intervention group will initially receive prepared MTF (low carbohydrate, and low-fat meals, which have been shown to improve glycemia in people with prediabetes) delivered by Moveable Feast (MFeast) (10 meals weekly; Tailored Medical Nutrition Therapy (MNT) delivered by dieticians from MFeast via monthly phone calls and focused on two high yield topics only: ↓sugar-sweetened beverages and ↑ fruit and vegetable consumption; Lactation nutritional snack bundles to boost milk supply + structural support for breastfeeding/ pumping via lactation consultants and pumping supply subsidization; culturally-adapted seasoning bundles; and dependent meal boxes for children in the household (i.e., will include 10 developmentally appropriate snack and small meal bundles, for up to 24 weeks. At postpartum week 8, participants will be offered a transition from prepared medically tailored meals to Instacart fresh food delivery (medically tailored via study team-crafted virtual grocery store) for 16 more weeks.
Those assigned to the "MFeast Usual Care" group will receive prepared MTF delivered by MFeast and as-needed MNT from 1 to 24 weeks postpartum.
