About this study
Official title: Building on the Dietary Guidelines: 3 Dietary Pattern (DG3D) Study - Testing a Teaching Kitchens and Food is Medicine Approach for Type 2 Diabetes Prevention
The goal of this pilot clinical trial is to examine how receipt of ingredients for a Mediterranean diet (with or without nutrition classes) impacts Type 2 Diabetes Mellitus risk factors among adults in the US South. The main question it aims to answer is:
- Will greater improvements in diet quality (HEI Score) and body weight be seen in the group that receives grocery delivery and nutrition classes (TK+FiM) compared to the group receiving grocery delivery only (FiM only)?
Read more
Researchers will evaluate the changes in diet quality and body weight among participants in each group to see which group experiences greater improvements.
Participants will:
- be randomly assigned to either receive weekly grocery deliveries and attend weekly virtual nutrition classes for 4 weeks or receive weekly grocery deliveries only.
- be asked to complete surveys/questionnaires at the baseline and 4-week timepoints in the study.
- be asked to participate in a post-study focus group to talk about their experiences during the intervention.
- Conditions
- Type 2 Diabetes (T2DM), Obesity & Overweight
- Being tested
- Dietary Intervention Teaching Kitchen (TK) Classes, Food is Medicine Grocery Provision (FiM)
- Medical subject headings
- Diabetes Mellitus, Type 2, Obesity, Overweight
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Dietary Intervention Teaching Kitchen (TK) ClassesBehavioural
Participants will attend virtual classes once per week for 4 weeks.
Food is Medicine Grocery Provision (FiM)Behavioural
Participants will receive a delivery of up to $25 worth of grocery ingredients that support a Mediterranean diet each week for 4 weeks.
| Study group | Role | What they receive |
|---|---|---|
| FiM only | Active comparator | Active control receiving weekly grocery delivery with no virtual teaching kitchen (TK) Mediterranean diet intervention Receives: Behavioral: Food is Medicine Grocery Provision (FiM) |
| FiM+TK | Experimental | Virtual teaching kitchen (TK) Mediterranean diet intervention plus weekly grocery delivery Receives: Behavioral: Dietary Intervention Teaching Kitchen (TK) Classes; Behavioral: Food is Medicine Grocery Provision (FiM) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Changes in Healthy Eating Index Score
Changes in dietary quality as assessed by the Healthy Eating Index (HEI-2020; scale range 0-100 where a higher score means better dietary quality)
Measured: 4 weeks
Changes in body weight
Changes in body weight
Measured: 4 weeks
