Nutrition Outreach and Understanding: Research In Serving Hearts Through Healthy Eating And Tailored Support

This study is a human-centered, three-arm, parallel-group, randomized control, implementation trial (n=75) to compare MTM (Medically Tailored Meals) only (14 meals delivered weekly for 10 weeks) vs. MTM + SMA (Shared Medical Appointments; once weekly sessions for 10 weeks) vs. a wait-list control group (MTM-Later) in patients with hypertension, type 2 diabetes, obesity, and/or metabolic syndrome. All intervention components will be culturally congruent (e.g., MTMs will include food that converges with culturally relevant diets and SMAs will be delivered by individuals with racial concordance to the target community). Primary outcomes will be implementation (recruitment and retention rates) and feasibility (engagement and satisfaction). Participants will be recruited from Cleveland Clinic's South Pointe Hospital in Warrensville Heights, a predominantly Black community with low socioeconomic status and high cardiovascular disease morbidity.

Key information

About this study

Subjects will be randomized into one of the three arms within the study:

Medically Tailored Meals (MTMs):

Collaborative agreements are in place with Performance Kitchen to prepare 2 meals/day for 7 days/week for 10 weeks at a discount for all participants (n =75) for this trial. Meals will be prepared based on evidence-based nutritional recommendations for the Mediterranean diet and that align with 2021 American Heart Association Dietary Guidance. Individuals randomized to MTMs will receive electronic educational materials from the MTM + SMA group after the completion of the post-intervention study assessment.

Medically Tailored Meals + Shared Medical Appointments (MTMs + SMAs):

Identical MTMs that are provided in the MTM only group will also be provided in the MTM + SMA group. The SMA will be delivered weekly for 10 weeks and will be modeled after the investigator's pilot study. This includes practice with behavior change principles (i.e., selection of healthy food options). The provider, dietician, chef, and health coach will be members of the Black community to ensure racial concordance between educators and participants, a critical feature that improves communication, trust, and health outcomes in behavioral health interventions. The provider, dietician, and health coach are professionals currently employed within the Department of Wellness and Preventive Medicine. Fidelity will be ensured by using a session fidelity checklist that will be completed by each facilitator. To maximize retention, during consent via (telephone or in-person the study coordinator will establish rapport and set study expectations, including what SMAs entail and the time commitment for the session to minimize attrition. SMA visit reminder emails will be sent to participants through their EHR portal and/or via email.

Medically Tailored Meals - Later (MTM-Later):

The inclusion of a MTM-Later arm will provide a rigorous test of outcomes and is necessary given limited data about MTM implementation, engagement, and clinical outcomes in Black, underserved communities. MTM-Later participants will receive MTMs (same quantity and frequency) as the two other groups after the completion of the post-intervention study assessment. To avoid differential drop-out and incomplete assessments in the MTM-Later group, this group will be offered culinary tools at the start of the intervention to build trust and confidence that they will indeed receive the meals and educational materials at the end of the study assessment period. This group will act as the Waitlist Control group.

All groups will receive a set of surveys to be given at baseline and weeks 5 and 10 for exploratory outcomes. All groups will also have labs drawn at baseline and week 10 to measure secondary outcomes such as change in HbA1c.

4 focus groups will also be conducted (2 groups from each treatment arm) to understand barriers and facilitators to engaging in each of the active treatments.

Treatment and study plan

Medically Tailored Meals

Other

Meals culturally tailored to provide essential nutrition

Primary outcomes

  1. Recruitment Rate

    Time frame: Baseline through Week 10

    Recruitment is a measure of treatment implementation. Recruitment rate will be measured by # of participants enrolled in study/# passed eligibility screening.

  2. Retention Rate

    Time frame: Baseline through Week 10

    Retention is a measure of treatment implementation. Retention rate will be measured by # of completed assessments at week 10/# randomized to treatment arm.

  3. SMA Attendance

    Time frame: Baseline through Week 10

    Engagement will be assessed by Shared Medical Appointment (SMA) session attendance over the 10 week period.

  4. MTMs Consumed

    Time frame: Baseline through Week 10

    Engagement will be assessed by proportion of Medically Tailored Meals (MTMs) consumed.

  5. Satisfaction of the Intervention

    Time frame: Baseline through Week 10

    Satisfaction of MTM vs. MTM + SMA will be assessed using the Net Promoter Score (scale of 0 to 10; 9-10 being promoters, 7-8 being passives, and 0-6 being detractors)

Secondary outcomes

  1. Eating Behavior

    Time frame: Baseline and Week 10

    Changes in eating behavior will be measured using the Mini-EAT (Eating Assessment Tool) and Fast Food/Restaurant Frequency Questionnaires.

  2. Body Weight

    Time frame: Baseline and Week 10

    Body weight will be measured in pounds.

  3. Waist/Hip Circumference

    Time frame: Baseline and Week 10

    Waist/Hip circumference will be expressed as a ratio.

  4. Systolic and Diastolic Blood Pressure (mmHg)

    Time frame: Baseline and Week 10

    Systolic and diastolic blood pressure will be measured and expressed as mmHg.

  5. Hemoglobin A1c (HbA1c, mmol/mol)

    Time frame: Baseline and Week 10

    Hemoglobin A1c will be evaluated through peripheral blood draw to assess diabetes control.

  6. Trimethylamine N-oxide (TMAO, uM)

    Time frame: Baseline and Week 10

    Trimethylamine N-oxide will be evaluated through peripheral blood draw to assess cardiovascular disease risk.

  7. Uric Acid (mg/dL)

    Time frame: Baseline and Week 10

    Uric Acid will be evaluated through peripheral blood draw to assess cardiovascular disease and diabetes risk.

  8. Vitamin D 25 Hydroxy (ng/mL)

    Time frame: Baseline and Week 10

    Vitamin D 25 Hydroxy will be evaluated through peripheral blood draw to asses for Vitamin D deficiency.

  9. High Sensitivity C-Reactive Protein (hsCRP, mg/dL)

    Time frame: Baseline and Week 10

    High Sensitivity C-Reactive Protein will be evaluated through peripheral blood draw to assess inflammation.

Other outcomes

  1. Qualitative characterization of participants' lived experiences and engagement

    Time frame: Week 10

    4 focus groups (n=5 in each group, 2 groups from each treatment arm - MTM and MTM + SMA) will be conducted to understand barriers and facilitators to engaging in each of the active treatments.
