About this study

This is a pragmatic randomized controlled trial (pRCT) that aims to test the effect of produce provision, diabetes education, and community referrals on hemoglobin A1c levels in individuals with type 2 diabetes experiencing food insecurity.

Read the detailed description

LINK (Linking Education, Produce Provision, and Community Referrals to Improve Diabetes Care is a 6-month pragmatic randomized controlled trial (pRCT) using a 2x2 factorial design to prospectively enroll study participants with type 2 diabetes and food insecurity into one of four study arms. The four study arms are: 1) Mid-Ohio Farmacy (receiving weekly produce through a consortium of local food banks); 2) Mid-Ohio Farmacy + Cooking for Diabetes (Cooking for Diabetes is a 6-week diabetes and culinary education intervention); 3) Mid-Ohio Farmacy + Health Impact Ohio Pathways Hub (The Pathways Hub uses a community health worker model to meet with participants, evaluate and address non-medical, health-related social needs); and 4) Mid-Ohio Farmacy + Cooking for Diabetes + Health Impact Ohio Pathways Hub). Participants will be enter

Participants will be randomized using a 1:1:1:1 stratified randomization scheme built into Research Electronic Data Capture (REDCap) at the participant level.

Primary and secondary outcomes will be collected at baseline, 3 and 6 months.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Hemoglobin A1c

    measures average blood sugar levels over the past 3 months

    Measured: 3 months

Secondary outcomes (5)
  1. Change in Hemoglobin A1c

    measures average blood sugar levels over the past 3 months

    Measured: 6 months

  2. Change in diabetes self-efficacy assessed by the Diabetes Self-Efficacy Scale

    Diabetes self-efficacy measured via the diabetes self-efficacy scale. The Diabetes Self-Efficacy Scale has a minimum score of 10 and a maximum score of 80. A higher score indicates higher diabetes self-efficacy.

    Measured: 3 months

  3. Change in diabetes self-efficacy assessed by the Diabetes Self-Efficacy Scale

    Diabetes self-efficacy measured via the diabetes self-efficacy scale. The Diabetes Self-Efficacy Scale has a minimum score of 10 and a maximum score of 80. A higher score indicates higher diabetes self-efficacy.

    Measured: 6 months

  4. Change in food security assessed using the 18-item U.S. Household Food Security Survey Module

    Food security will be assessed using the 18-item U.S. Household Food Security Survey Module.

    For households with one or more children:

    • Raw score zero-High food security
    • Raw score 1-2-Marginal food security
    • Raw score 3-7-Low food security
    • Raw score 8-18-Very low food security

    For households with no child present:

    • Raw score zero-High food security
    • Raw score 1-2-Marginal food security
    • Raw score 3-5-Low food security
    • Raw score 6-10-Very low food security

    Measured: 3 months

  5. Change in food security assessed using the 18-item U.S. Household Food Security Survey Module

    Food security will be assessed using the 18-item U.S. Household Food Security Survey Module.

    For households with one or more children:

    • Raw score zero-High food security
    • Raw score 1-2-Marginal food security
    • Raw score 3-7-Low food security
    • Raw score 8-18-Very low food security

    For households with no child present:

    • Raw score zero-High food security
    • Raw score 1-2-Marginal food security
    • Raw score 3-5-Low food security
    • Raw score 6-10-Very low food security
