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.
