Circadian Mechanisms of Glycemic Control and Cardiovascular Risk in Adults With Type 1 Diabetes
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.
• Adults 18-50 years with a clinical diagnosis of T1D for at least one year
• Report habitual sleep irregularity ≥1 hour/week
• Desire to improve sleep, and own a smartphone (Android or iPhone)
