Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18-50 with a clinical diagnosis of type 1 diabetes for at least one year and who experience habitual sleep irregularity.

Probably not a fit

Patients with severe hypoglycemia history, significant medical comorbidities, or those using sleep medications may not benefit from this study.

What this trial studies

This study investigates the relationship between sleep regularity and cardiovascular disease risk in adults with type 1 diabetes (T1D). It aims to understand how enhancing sleep stability through behavioral interventions can improve glycemic control and reduce cardiovascular risks. The study will involve a 4-week intervention targeting sleep stability in 80 participants, examining the mechanisms by which sleep impacts metabolic health. The findings could provide insights into effective strategies for managing T1D and associated cardiovascular risks.

Why it matters

Potential benefit: If successful, this study could lead to improved cardiovascular health and glycemic control for patients with type 1 diabetes.

How similar studies have gone: Previous studies have shown promising results in improving glycemic control through sleep interventions, suggesting potential success for this approach.
