Sleep Optimization to Improve Glycemic Control in Adults With Type 1 Diabetes
Source: ClinicalTrials.gov · Last updated 27 Aug 2026
Brief summary (registry, in English)
Up to 40% of adults with type 1 diabetes have insufficient sleep which is associated with negative health consequences including poor blood glucose control and greater diabetes complications. In this study, a sleep intervention (Sleep-Opt) that uses wearable sleep tracking technology, telephone coaching and informational content designed to improve sleep and glycemic control in working-age adults with type 1 diabetes. Sleep-Opt could lead to reduced development of diabetes complications and improve quality of life for adults with type 1 diabetes.
