Clinical Trial Summary

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	2 hour plasma glucose levels assessed using Oral Glucose Tolerance Test (OGTT)	Test will be done using 75 g oral glucose load with measurement of 2-hour plasma glucose levels. Obtained by electronic health records (EHR) or lab request.	4-12 weeks postpartum
Other	HbA1C	HbA1C assessed by EHR or lab request	3 and 6 months postpartum
Other	Percent time spent in euglycemia as assessed by participant blinded Continuous Glucose Monitor (CGM) sensor	Will be measured by % time in euglycemia (glucose 70-139)	3 and 6 months postpartum
Other	Percent time spent in hyperglycemia assessed by participant blinded CGM sensor	Will be measured by % time with hyperglycemia (glucose >140)	3 and 6 months postpartum
Other	Postprandial glucose excursions assessed by participant blinded CGM sensor	Postprandial glucose is calculated using the incremental area under the curve (AUCi) of blood glucose (mg/dL) over a period of time. The AUCi will be calculated for 1 hour (AUCi 0-60) after a meal. The participants will have the sensors on for 10 days, and will be asked to document their meals to correlate with calculated AUCi's.	3 and 6 months postpartum
Other	Mean daily glucose	Mean daily glucose for 10 days in months 3 and 6 postpartum	3 and 6 months postpartum
Primary	Participant Enrollment Rate	Participant Enrollment Rate as assessed by the percentage of participants consented/enrolled compared to the total eligible participants	6-8 months postpartum
Primary	Participant Retention	Retention as assessed by the percentage of participants completing all study follow-up visits among all enrolled participants.	6-8 months postpartum
Primary	Adherence as assessed by self-reported food consumption scores and photographs sent to the study team via secure messaging app	Consumption scores range from 0%, 25%, 50%, 75%, or 100%, indicating the amount of food consumed the prior week (self and dependents scores reported).	6-8 months postpartum
Primary	Satisfaction as assessed by focus groups and the 8 item Client Satisfaction Questionnaire- (CSQ-8)	Participants rate satisfaction with the intervention's meal quality, delivery service, and likelihood of recommending the service to others at study completion, to assess the extent to which the intervention met their needs and preferences. Scores range from 8 to 32, with higher values indicating higher satisfaction.	6-8 months postpartum
Primary	Participant Engagement assessed by frequency and quality of meal discussions	Analyze the messaging app and Slack Channel to determine the frequency and quality of discussions about meals and recipes.	1-6 months postpartum
Secondary	Dietary Quality as assessed by the Healthy Eating Index (HEI) 24-hour recall	The HEI uses a scoring system to evaluate a set of foods. The scores range from 0 to 100. An ideal overall HEI score of 100 reflects that the set of foods aligns with key dietary recommendations and dietary patterns published in the Dietary Guidelines.	Baseline, 3 and 6 months postpartum
Secondary	Stress assessed by the 4-item Stress Scale.	The 4-item Stress Scale consists of 4 questions. The lowest total score is 0 and the highest total score on the scale is 16. Higher scores are correlated to more stress.	Baseline, 3 and 6 months postpartum
Secondary	Food Insecurity measured using a 6-item Food Insecurity scale.	The 6-item Food Insecurity scale uses a subset of the standard 18 item food security scale. The Scores on the scale range from 0-6 with 0-1 indicating high or marginal food security, 2-4 indicating low food security and 5-6 indicating very low food security	Baseline, 3 and 6 months postpartum
Secondary	Postpartum Weight Retention in pounds as assessed by the difference in self-reported pre-pregnancy weight and postpartum weights	Will be assessed by calculating the difference in self reported pre-pregnancy weight (with Electronic Health Record validation) and postpartum weights (study provided scales)	Baseline, 3 and 6 months postpartum
