Impact of a Sleep Debt in Middle-Aged and Older Adults
NCT00817700 · View on ClinicalTrials.gov ↗
Study Summary
This project has 6 aims. 1. To examine the impact of recurrent partial sleep loss in young, middle-aged and older men and women. Sleep will be restricted to 4 hours. 2. To test the hypothesis that extending bedtimes to allow for sleep recovery will reverse the metabolic, endocrine, and cardiovascular and neuro-behavioral alterations resulting from sleep restriction. Sleep will be extended to 12 hours following the 4 hour sleep restriction. 3. To test the hypothesis that there are age and gender differences in the total amount of sleep recovery obtained during the week of 12-hour bedtimes. 4. To test the hypothesis that there are age and gender differences in sleep capacity (the amount of time an individual can sleep per night when there is no sleep debt). 5. To test the hypothesis that sleep capacity is partly determined by baseline levels of slow-wave sleep and slow-wave activity. 6. To determine whether sleep capacity is related to sleep need by examining metabolic, endocrine, cardiovascular and neuro-behavioral changes with the amount of the individual sleep debt.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00817700
The ClinicalTrials.gov registry entry for NCT00817700 describes a study currently listed as completed. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 72 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of Chicago, which has 846 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Sleep Restriction appearing as the primary indexed condition, and to 1 intervention — of which Sleep restriction is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00817700 reports 1 study location spanning 1 distinct geographic area — top geographies include Illinois. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
