Building and Sustaining Exercise Habits for Adults With Type 1 Diabetes
Informatics-Based Digital Intervention to Promote Safe Exercise in Middle-Aged Adults With Type 1 Diabetes and Other Absolute Insulin Deficiency Diabetes - A Pilot Efficacy Study
Yale University
60 participants
Jul 10, 2025
INTERVENTIONAL
Conditions
Summary
The challenges of living with type 1 diabetes often stand in the way of getting enough exercise. Continuous blood sugar monitoring has revolutionized type 1 diabetes care but remains underutilized to sustainably support exercise and related behaviors. This remote participation-based research will develop a mobile application that delivers personalized encouragement and data-driven health insights based upon patterns in blood sugar, exercise, mood, and sleep, to assist people with type 1 diabetes in exercising more frequently and confidently. You do not need to live in Connecticut to participate, as there will be no required in-person visits during the study.
