Circadian Mechanisms, Glucose, and CV Risks in T1D
Circadian Mechanisms of Glycemic Control and Cardiovascular Risk in Adults With Type 1 Diabetes

INTERVENTIONAL
Conditions
Summary
People with type 1 diabetes are disproportionately affected by cardiovascular disease (CVD). Short and irregular sleep have been associated with cardiovascular risk in this population. Improving sleep regularity has been associated with improved glycemic markers however mechanisms by which improving sleep regularity improves metabolic and cardiovascular health is not known. The investigators propose to conduct a mechanistic study using a sleep stability manipulation. This proposal will advance the understanding of mechanisms by which improving sleep regularity influences glycemic control and cardiovascular risk in T1D.

Interventions
The sleep stability intervention will consist of three theory-based intervention components our team has developed and used in prior interventions: 1) self-monitoring using a wearable sleep tracker (Fitbit). This is well-liked by participants and increases awareness of their sleep goals. 2) Accountability coaching via weekly check-ins and daily monitoring of participants' wearable sleep tracking data and a coaching protocol.
