Conditions
Brief 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 chronic hypertension-a potent contributor to disparate mortality among Black women. * To conduct a pilot randomized control trial to test the feasibility, acceptability, and effectiveness of a multi-component Medically Tailored Food (MTF) intervention, MFeast 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 and 6 months post-delivery after the baseline survey. * Submit anthropometric data (e.g. weight and blood pressure)
Detailed 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 hypertensive disorders of pregnancy (HDP). 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 prepared MTF food supplier Moveable Feast Baltimore. The intervention group will initially receive 10 weekly prepared heart-healthy meals from MFeast; 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 10 weekly prepared heart-healthy meals from Moveable Feast (MFeast).

Masking description
Due to the nature of the intervention, blinding of participants or MFeast staff is not possible, but data collectors will be blinded to arm.
Intervention model description
The study design is a two parallel-arm pilot randomized controlled trial. The investigators will be applying the principles of a hybrid type 1 implementation-effectiveness randomized controlled trial.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Participant Engagement assessed by frequency and quality of meal discussions | 1-6 months postpartum | Analyze the messaging app and Slack Channel to determine the frequency and quality of discussions about meals and recipes. |
| Participant Enrollment Rate | 6-8 months postpartum | Participant Enrollment Rate as assessed by the percentage of participants consented/enrolled compared to the total eligible participants. |
| Participant Retention | 6-8 months postpartum | Participant Retention as assessed by the percentage of participants completing all study follow-up visits among all enrolled participants. |
| Adherence as assessed by self-reported food consumption scores and photographs | 6-8 months postpartum | Adherence as assessed by self-reported food consumption scores and photographs sent to the study team via secure messaging app. Food Consumption scores range from 0%, 25%, 50%, 75%, or 100%, indicating the amount of food consumed the prior week (self and dependents scores reported). |
| Satisfaction as assessed by focus groups and the 8 item Client Satisfaction Questionnaire- (CSQ-8) | 6-8 months postpartum | 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Dietary Quality as assessed by the Healthy Eating Index (HEI) 24-hour recall | Baseline, 3 and 6 months postpartum | 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. |
| Stress assessed by the 4-item Stress Scale | Baseline, 3 and 6 months postpartum | The 4-item Stress Scale consists of 4 questions. The lowest total score is 0 and the highest total score is 16. Higher scores are correlated to more stress. |
| Food Insecurity measured using a 6-item Food Insecurity Scale | Baseline, 3 and 6 months postpartum | 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 |
| Postpartum Weight (pounds) Retention as assessed by the difference in self-reported pre-pregnancy weight and postpartum weights | Baseline, 3 and 6 months postpartum | Will be assessed by calculating the difference in self reported pre-pregnancy weight (with Electronic Health Record validation) and postpartum weights (study provided scales) |
Other
| Measure | Time frame | Description |
|---|---|---|
| Blood Pressure as assessed by Bluetooth blood pressure cuff | Baseline, 3 and 6 months postpartum | Will be assessed using systolic and diastolic pressures classified per hypertension guidelines |
