About this trial

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.

Eligibility criteria

Qualifiers

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.

Disqualifiers

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
