Brief summary
This is a three-arm, parallel randomized trial study that will assess the impact of home delivery of medically-tailored meals (MTM) to community-dwelling older adults living with diabetes mellitus type 2 on measurements of diabetes control, mental health, and other exploratory outcomes such as healthcare use.
Detailed description
This study aims to: 1. Assess the impact of medically-tailored meals program on diabetes management and mental health in comparison to usual care without such program. 2. Assess the differential impact of two delivery models being considered for payment by the health system on diabetes management and mental health: once-a-week frozen drop shipment model versus daily warm meal delivery model that is more complex to implement but allows for human connection and easier meal preparation. Implementation of program: Meals on Wheels (MoW) of Central Texas (MOWCTX) in Austin, Texas, will provide the meals and delivery service in this study. Meals are all medically tailored (diabetes friendly) and design by MOWCT's team of Registered Dietitians. Participants: Older adults, 55 and over, living in the Austin city limits with poorly controlled diabetes; Inclusion criteria: * Adult 55-90 * Hemoglobin A1C \>=7.5 (as measured at baseline) * Living in Austin city limits and within a MOWCTX daily delivery route * Interested and available to receive meals during delivery window time * Has access to a freezer and a microwave * Pass a MOWCTX background check Trial: Eligible participants will be recruited from selected Federally Qualified Health Centers in the Austin area, MOWCTX clients on waitlist, and other (e.g. Medicaid recipients). Participants will be randomized to one of three arms: 1) Waitlisted control; 2) Weekly frozen drop shipment of MTM 3) Daily Warm delivery of MTM with in-person check-ins during delivery. Phase 1 (first 6 months) The intervention arms will receive their assigned method of meal delivery (weekly frozen or daily warm), for a total of 10 meals a week, including two main meals per day and snacks. The control arm will not receive any meals during this phase. All arms will receive printed educational materials at baseline. Phase 2 (month 6 to 12) All arms will receive 2-4 meals a week (depending on participant's availability) delivered via the traditional meal services from MOWCTX, which includes one hot meal plus a snack delivered daily. Meal delivery can also include 1 or more frozen meals to account for a total of 5 meals per week. Primary outcome is Hemoglobin A1C and secondary outcomes include depression as measured by PHQ-8 and other mental health measures.
Interventions
BEHAVIORALWaitlist
Phase 1 (6 months) • Educational materials on such topics as healthy eating for diabetes.
BEHAVIORALMedically tailored meals - Daily delivery with human interaction
Phase 1 (6 months) * Educational materials on such topics as healthy eating for diabetes, in addition to materials on meal planning and instructions. * Food: 10 MTM a week: mix of hot and frozen, and 5-10 snacks per week. Meals and snacks offer approx. 1200 kcal per day. * Delivery: 3 to 5x per week. Each delivery day, one meal is warm, the other is frozen. Depending on the participant's availability (3-5 days/week), more frozen meals will be given one day to account for a total of 10 meals every week. * Engagement: MOWCTX's trained volunteers and/or paid delivery drivers delivering the meals will have a brief social interaction (at minimum in-person hand-off & visual check) with the participant.
BEHAVIORALMedically tailored meals - Weekly delivery with no human interaction
Phase 1 (6 months) * Educational materials on such topics as healthy eating for diabetes, in addition to materials on meal planning and instructions. * Food: 10 frozen MTM and 5-10 healthy snacks (with the goal of providing 2 meals and 1-2 snacks for 5 days of the week). Meals and snacks offer approx. 1200 kcal per day. Nutritionally similar and frequently the same meal as that delivered in the daily delivery arm. * Delivery: 1x per week shipment. * Engagement: Meals are shipped to the participant's home. No human engagement.
BEHAVIORALMedically tailored meals - Standard MOWCTX delivery with human interaction
Phase 2 (6 months) * Food: 5 MTM a week plus snacks. Planned to offer approx. 600 kcal per day. * Delivery: 2 to 4x a week (depending on participant availability), including daily delivery of 1 hot MTM plus a cold bag (with healthy snacks), with one day or more (depending on the 2 to 4x a week delivery schedule participant is on) also including 1 frozen MTM to total 5 meals per week. * Engagement: MOWCTX's trained volunteers and/or paid delivery drivers delivering the meals will have a brief social interaction (check-in) with the participant. * MOWCTX Standard Wraparounds: Participants will have access to a case manager to assist with additional resources within the community and for additional support if needed (e.g., grocery shopping assistance, home repairs, and pet care).

Masking description
Research staff responsible for data collection at the sites are blinded to the arm allocation of the participant. At follow-up time points, however, a set of questions is asked that are different for each of the three arms on food intake and preferences, and for arm 2, for the experience of delivery. To minimize influence of unblinding, we will actively cross-assign research staff to different locations for follow-up visits.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Hemoglobin A1C (HbA1c) | Baseline to 6 months | Finger stick point-of-care portable device. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Program meal consumption | 6 months, 12 months | For frozen and warm meals, self-report on what was actually consumed (customized survey) |
| Diet quality as assessed by NHANES DSQ | 6 months, 12 months | Self-report of food consumption patterns |
| Loneliness as assessed by scores on the 3-item UCLA Loneliness Scale | 6 months, 12 months | Respondents rate each item as 'Never' , 'Rarely', 'Sometimes' or 'Often'. Scores range from 3 to 9. Higher numbers imply greater loneliness. |
| Depressive symptoms as assessed by scores on the the 8-item Depression Health Questionnaire (PHQ-8) | 6 months, 12 months | Respondents answer to eight questions that reflect the DSM-IV diagnosis criteria of depressive disorders. These questions ask how often in the past 2 weeks the respondent had experienced a particular depressive symptom. Each answer is scored from 0 to 3 and then summed. Total scores go from 0 and 24 points, with higher scores indicating greater depressive symptoms. |
| Anxiety symptoms as assessed by the 7-item Generalized Anxiety Disorder Scale (GAD-7) | 6 months | Investigators will use the Generalized Anxiety Disorder Scale (GAD-7) to measure anxiety. Scored from 0-3, and a score of 0 indicates lower levels of anxiety while a score of 3 indicates higher levels of anxiety. |
| Diabetes Self-Efficacy as assessed by scores on the Stanford Self-Efficacy for Diabetes Scale 8-item | 6 months, 12 months | Respondents are asked to score their level of confidence (scale from 1, not at all confident, to 10, totally confident) at the present time in doing tasks related to diabetes management (e.g., diet behavior, physical activity, measuring blood glycemia and others). Higher scores indicate higher self-efficacy. |
| Change in Hemoglobin A1C | Baseline to 9 &12 months, 6 months to 12 months. | Finger stick point-of-care portable device. |
| Health Status and Quality of Life as assessed by scores on Short-form 12-item (SF-12) | 6 months, 12 months | Measures physical and mental health status. Summary scores range from 0-100, with higher scores indicating a better self-reported level of health. |
| Healthcare delay due to cost | 6 months, 12 months | Self-report of delaying healthcare due to cost. 1 item. |
| Emergency room visits | 6 months, 12 months | Self-report of going to a hospital emergency room. |
| Food-basic needs trade-offs (3 items) | 6 months, 12 months | Self-report of trading off paying for food vs. paying for medicine or medical care, for utilities, and for housing |
| Medication underuse due to cost (2 items) | 6 months, 12 months | Self-report of not acquiring a prescribed medication or took reduce dosage due to cost. |
| Food security status as assessed by the USDA Food Security Survey Module: Six-Item Short Form | 6 months, 12 months | Self-reported with a 30-day lookback period. The sum of affirmative responses to the six questions in the module is the household's raw score on the scale. Higher scores indicate greater food insecurity. |
