Study summary

This study evaluates the impact of the hybrid closed-loop insulin delivery systems on sleep in youth with type 1 diabetes and their parents. Activity watches, surveys and device downloads are used to evaluate sleep in these participants.

Read the detailed description

Sleep is important for everyone, including youth with type 1 diabetes. New technology has shown improvements in glycemic variability, especially overnight. This study evaluates the impact of advanced hybrid closed-loop insulin delivery systems on sleep for both youth with type 1 diabetes and their parents. Study measures include wearing an actigraphy watch and completing a sleep diary for 7 days and taking surveys on sleep and psychosocial measures. Study measures occur prior to starting the hybrid closed-loop system, immediately after starting the system and at 3 and 6 months after starting the system.
