Sleep Stability and Heart Health in Type 1 Diabetes

This study is looking at how improving sleep regularity might help people with type 1 diabetes (T1D) manage their blood sugar (glycemic control) and reduce their risk of heart problems (cardiovascular disease). Researchers will use a "sleep stability intervention" which involves tracking sleep with a wearable device like a Fitbit to help participants improve their sleep habits. They want to understand the exact ways that better sleep affects these health outcomes. You might be able to join if you are 18-50 years old, have had T1D for at least a year, have irregular sleep, and want to improve your sleep. The study will measure changes in your blood sugar and insulin sensitivity over 12 weeks. The current status of this study is unclear, and it plans to enroll 100 participants.

Inclusion

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)

Exclusion

Self-reported A1C within the past 6 months ≥10%
insomnia symptoms defined as Insomnia Severity Index score ≥15
history of restless leg syndrome
history of severe hypoglycemia (defined as hypoglycemic episode that results in loss of consciousness, seizure, or requiring emergency room visit or hospitalization) within the past 6 months
rotating shift or night work or routinely sleeping after 3 AM.
use of sleep medications/aids, significant medical comorbidities (such as heart failure, cirrhosis, chronic obstructive pulmonary disease requiring oxygen, active treatment for cancer, on renal replacement therapy \[dialysis\])
depression (Patient Health Questionnaire 8 \[PHQ-8\] score ≥15)
history of stroke with neurological deficits
