Further study details as provided by University of Chicago:

Primary Outcome Measures:
  • Comparison of chronobiological profiles of renin/aldosterone, sympatho-vagal balance and CV function in CKD subjects to controls at baseline and after extended sleep in CKD subjects and after decreased time and quality of sleep in control subjects. [ Time Frame: Immediately after intervention. ]

Enrollment: 40
Study Start Date: October 2008
Study Completion Date: July 2011
Primary Completion Date: June 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: Baseline
CKD subjects and healthy, matched controls will have measures of cardiovascular function (BP, HR) measure of hormonal fluid balance (renin/aldosterone) measure and measures of glucose metabolism (response to glucose load and over 24 hr profile) with 3 days of habitual sleep time
Experimental: CKD- Sleep extension
Measures as in baseline but with bed time increased by 2 hours
Other: CKD- sleep extension
Sleep will be increased by 2 hours each night for 3 nights
Other Name: Sleep intervention
Experimental: Controls short sleep
Measures as in baseline but with sleep disruption
Other: Controls Short sleep
Healthy control subject's bedtime will be decreased by 2 hours/night with acoustic sleep disruption
Other Name: Sleep intervention
