Impact of Sleep Extension in Adolescents
NCT03500458 · View on ClinicalTrials.gov ↗
Study Summary
Many teenagers do not get enough sleep. Obesity and diabetes are increasing in teenagers as well. This study plans to learn more about sleep and insulin resistance (insulin not working) in teenagers, and how these things may be related depending on sleep. This is important to know so that the investigators understand how sleep may play a role in health conditions like extra weight gain (increased food intake and less physical activity) and diabetes. To answer this question, the investigators plan to enroll teenagers who get \<7 hours of sleep on school nights and measure changes in insulin sensitivity and dietary intake after a week of typical sleep (sleeping on their normal school schedule) and a week of longer sleep (spending 1+ hour longer in bed each night).

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT03500458
The ClinicalTrials.gov registry entry for NCT03500458 describes a study currently listed as active not recruiting. 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 75 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of Colorado, Denver, which has 1,447 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 3 conditions, with Sleep appearing as the primary indexed condition, and to 1 intervention — of which Sleep Extension 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: NCT03500458 reports 1 study location spanning 1 distinct geographic area — top geographies include Colorado. 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.
