Not Applicable

Completed

• Conditions: Apnea; Obstructive Sleep Apnea (OSA); Obesity
• Interventions: Other: Restriction; Other: Extension

• Registration Number: NCT00965783
• Lead Sponsor: University of Chicago

Brief Summary

To test whether baseline levels of slow wave activity (SWA) during sleep are lower in obese adults, and even lower in persons with sleep disordered breathing (SDB) compared to lean adults.

To compare levels of SWA in individuals in relation to their sleep time, blood pressure, heart rate, and markers of glucose metabolism.
