About
The objective of this protocol is to answer the questions: 1) Within food supplementation options, are mailed stock boxes superior to food vouchers in terms of achieving glycemic control? 2) Is the combination of mailed stock boxes and food vouchers superior to either food supplementation option alone? 3) Does providing diabetes education in combination with food supplementation lead to improved clinical outcomes compared to education alone? To address this gap in the literature, we propose a randomized controlled trial to test the separate and combined efficacy of monthly food vouchers to farmers market and monthly mailed food stock boxes layered upon diabetes education in improving glycemic control in low income, food insecure, AAs with Type 2 Diabetes (T2DM) using a 2x2 factorial design.
Full description
The overarching aim of this proposal is to conduct a 4-arm RCT to test the separate and combined efficacy of monthly food vouchers to farmers market and monthly mailed food stock boxes layered upon diabetes education in improving glycemic control in low income, food insecure, AAs with T2DM using a 2x2 factorial design. 300 patients will be randomly assigned to four groups of 75 patients each: 1) diabetes education alone; 2) diabetes education plus food vouchers; 3) diabetes education plus mailed stock boxes; and 4) diabetes education plus combined food vouchers and mailed stock boxes. Each patient will be followed for 12 months, with study assessments at baseline, 3, 6, and 12 months. Primary aim is efficacy of separate and combined interventions on HbA1c at 12 months post-randomization. Secondary aims are efficacy of separate and combined interventions on BP, LDL and QOL as well as cost-effectiveness at 12 months post-randomization.
Description of the LIFT-DM Intervention Group 1 - Diabetes Education Only: Individuals assigned to this group will receive diabetes education and skills training but will not receive food supplementation. Twelve 30-minute weekly sessions will be delivered via the telephone, with two 30-minute booster sessions at months 6 and 9.
Group 2 - Diabetes Education Plus Monthly Food Vouchers: Individuals assigned to this group will receive diabetes education and skills training and monthly food vouchers for use at local farmer's markets mailed to their home. Vouchers for $50 will be mailed monthly for 12 months.
Group 3 - Diabetes Education Plus Monthly Stock Boxes: Individuals assigned to this group will receive diabetes education and skills training and monthly stock boxes with diabetes appropriate food items mailed to their home. Stock boxes with foods valued at $50 will be mailed monthly for 12 months.
Group 4 - Diabetes Education Plus Combination of Monthly Food Vouchers and Stock Boxes: Individuals assigned to this group will receive diabetes education and skills training, monthly food vouchers for use at local farmer's markets mailed to their home, and monthly stock boxes with diabetes appropriate food items mailed to their home. Vouchers for $25 and stock boxes with food valued at $25 will be mailed monthly for 12 months. In essence, the combined group will still receive $50 worth of food supplementation monthly as combination of $25 vouchers and $25 mailed stock boxes.
