Adaptive Dietary Intervention (ADI) Leveraging Continuous Glucose Monitoring for Asian Americans With Type 2 Diabetes
NYU Langone Health
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").

Inclusion Criteria: * Eligible participants (N=120; 60 Chinese Americans and 60 Vietnamese Americans) * Community-dwelling adults aged ≥ 18 with independent living; * Diagnosed with T2D; * Hb1Ac\>7.0% * Self-identified as first- or second-generation Chinese or Vietnamese immigrants; * Able to communicate in English, Chinese, or Vietnamese. We will focus on Mandarin-, Cantonese- or English-speaking Chinese Americans because the two best-known and most-spoken variants of Chinese are Mandarin and Cantonese, who use the same writing system; * Have a smartphone, iPad, tablet, or Apple watch Exclu…
Interventions
- DeviceContinuous 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.
