Health Behavior Intervention for Adults With Type 1 Diabetes
Emory University
Summary
Type 1 diabetes (T1D) affects approximately 2 million Americans, and only 2 in 8 young adults ages 18-31 years achieve glycemic targets (glycated hemoglobin A1C \<7.0%). Achieving glycemic targets is associated with reduced risk of micro-and macrovascular complications. Sleep deprivation leads to impaired glucose tolerance and insulin sensitivity in adults without chronic conditions and with T1D. Promoting sleep in laboratory and natural environments contributes to improvements in insulin sensitivity, glucose levels, and distress symptoms in young adults without chronic conditions and more time in range in adolescents with T1D. Multiple dimensions of sleep health (alertness, timing, efficiency, and sleep duration) are associated with better achievement of glycemic targets in adults with T1D. Therefore, sleep health dimensions are appropriate therapeutic targets to improve glucoregulation and other diabetes self-management outcomes in this population. Our primary objective is to evaluate the immediate and short-term effects of a 12-week CB-sleep intervention compared to enhanced usual care (time balanced attention control) on actigraphy- and self-report derived sleep health dimensions and diabetes self-management outcomes (glycemia and distress symptoms) over 9-months (Stage II of the NIH Model for Behavior Change, ORBIT phase III). CB-sleep is guided by principles and practices from motivational interviewing and the Transtheoretical Model of Behavior Change with interactive stage-matched sessions.
Description
Overview: The investigators will conduct a powered randomized controlled trial (RCT) and recruit a contemporary cohort of 248 young adults with T1D and randomly assign them to one of two conditions: CB-sleep or a time-balanced attention control (enhanced usual care) condition. The study will evaluate the immediate and short-term effects of CB-sleep compared to enhanced usual care on actigraphy and self-report derived sleep health dimensions (aim 1), glycemia and other diabetes self-management outcomes (aim 2), and whether sleep health mediates associations between the CB-sleep and enhanced usu…
