Glucose and Activity Tracking for Sedentary Behavior Interventions in Older People With Type 2 Diabetes (TRACK T2D)

June 2, 2026 updated by: University of Minnesota
The overarching goal of this explanatory mixed methods study is to evaluate how older people living with type 2 diabetes (T2D) integrate continuous glucose monitor (CGM) and activity data in diabetes self-management, and how this technology supports reduced sedentary behavior (SB) and improved glucose control.
