NCT06915831 | RECRUITING | Sleep Apnea, Obstructive

Type 1 Diabetes and Obstructive Sleep Apnea
Sponsor:

University of Chicago

Brief Summary:

The purpose of the study is to investigate the role of sleep apnea in glycemic dysregulation in adults with Type 1 diabetes.

Condition or disease

Sleep Apnea, Obstructive

Type 1 Diabetes (T1D)

Intervention/treatment

Continuous positive airway pressure (CPAP)

Phase

NA

Detailed Description:

Obstructive sleep apnea (OSA) is a common sleep disorder characterized by recurrent collapse of upper airway during sleep, resulting in intermittent hypoxia, sleep fragmentation by transient arousals, and poor sleep quality. Continuous positive airway pressure (CPAP), applied at night, is considered the treatment of choice for persons who are diagnosed with OSA. Current evidence suggests that OSA is highly prevalent in adults with T1D and particularly those with moderate-to-severe OSA have poorer glycemic control. Our overall goal is to investigate the role OSA in glycemic dysregulation in adults with T1D.
