Adaptive Dietary Intervention (ADI) Leveraging Continuous Glucose Monitoring for Asian Americans With Type 2 Diabetes

Summary

The investigators will examine the feasibility, acceptability, and effect of an adaptive dietary intervention over 24 weeks (12-week intervention, 12-week follow-up) among Asian Americans with Type 2 diabetes. Participants (N=120; 60 Chinese Americans and 60 Vietnamese Americans) will be 2:1 randomized to one of two arms: adaptive dietary intervention or standard of care (SC). The intervention will begin with continued glucose monitoring (CGM) use only during weeks 0-4. At week 4, participants who achieve the glycemic control goal (at least an 8% increase in time in range \[TIR\] from baseline) will continue with the CGM alone during weeks 4-12 ("CGM Alone"); otherwise, culturally and linguistically adapted glucose excursion minimization (GEM) will be augmented with CGM ("CGM-GEM").

Interventions

• Device
  Continuous Glucose Monitoring (CGM)

  Participants will receive a walk-through for CGM use with the research staff, including insertion and initiation of CGM, alarm parameter settings, data sharing via LibreView, checking and reviewing CGM glucose values and trends via Libre app or CGM reader, and the relationship between food intake and CGM results.

• Behavioral
  Adaptive dietary intervention (GEM)

  Adapted glycemic excursion minimization (CGM-GEM).
