Pilot of Continuous Glucose Monitor-Augmented Food Is Medicine

Conditions studied: Nutrition, Type 2 Diabetes, T2DM, T2DM (Type 2 Diabetes Mellitus), Diabetes Education, Diabetes Type 2, Diabetes Mellitis

In brief

This study is designed to test the feasibility and preliminary efficacy of a continuous glucose monitor (CGM)-augmented food is medicine (FIM) intervention for adults with type 2 diabetes and nutrition or food insecurity. This study will learn if a FIM intervention ("intervention") that includes access to real-time CGM and nutrition counseling can increase engagement, improve glycemic management, and support healthy eating in this population, compared to the FIM intervention alone ("comparator"). At the study baseline, participants will be randomized to either the intervention or the comparator arm for 16 weeks. The intervention will occur during the first 12 weeks (phase 1: intervention phase) and will be compared to a standard FIM approach without CGM or counseling. Phase 2 (extension phase) will last 4 weeks and will consist of all participants in the intervention and comparator arm receiving both FIM and CGM for self-directed use. The study will also explore participant experiences through a series of semi-structured interviews with a subset of randomly selected participants to identify opportunities for scaling the intervention to a broader population.

You may qualify if…

Able to complete study activities in English
Aged ≥18 years
Type 2 diabetes as defined by self-report and confirmed by ICD-10 codes
Chart review will be conducted by the study team and a diagnosis of type 2 diabetes (E.11.xx) from either the problem list or a diagnosis linked to an encounter will be used as confirmation. Discrepancies in diagnosis codes will be resolved by review of provider notes within the past 3 years.

Receiving primary or specialty care within UNC Health as defined by at least one visit with a primary care provider or endocrine provider within the past year
Indication of a barrier to healthy eating consisting of report of food insecurity (defined as a score greater or equal to 1.0 on the 6-item USDA Food Security Survey Module (FSSM)) and/OR nutrition insecurity (defined as more often than 'Rarely' on the One-Item Gretchen Swanson Nutrition Screener, OR more often than 'Not Very Hard' on the Two-item Nutrition Security Screener (NSS))
Any positive screen on the FSSM, Gretchen Swanson Nutrition Screener, or NSS
No plans to move from the area for at least 4 months
Willing and able to provide written informed consent and participate in all study activities

You may not qualify if…

Type 1 or other diabetes
Use of insulin or secretagogues in the preceding 6 months
Use of CGM in the preceding 6 months
Inability to use CGM and related technology (e.g., the companion app), including lack of a smartphone that is compatible with Stelo (information on compatible phones available in Appendix 1) or known allergy to adhesive
Known psychosis or major psychiatric illness that prevents participation with study activities
Pregnancy or planned pregnancy in the next 4 months-glycemic targets are different for pregnant women compared to non-pregnant women with diabetes and our intervention is designed for non-pregnant glycemic targets
