Biomarkers of Increased Free Living Sleep Time

Status Recruiting

Clinical Trial Summary

This protocol will increase sleep duration in participants who maintain less than 6 hours sleep per night, to target the recommended 7 hours of sleep per night. The focus of this study is determine how increasing nightly sleep duration in these individuals who maintain less than 6 hours sleep per night changes their plasma metabolome and insulin sensitivity. The primary outcome will examine changes in branched-chain amino acids and the secondary outcome will examine changes in insulin sensitivity. The investigators will also determine if changes in plasma metabolites can be used as a biomarker to discriminate between adequate versus insufficient sleep.

Clinical Trial Description

Impaired sleep affects millions of people each year representing an important public health issue. This project will utilize metabolomics approaches to identify potential mechanisms underlying increased cardiometabolic risk associated with insufficient sleep and to identify potential biomarkers in the blood that respond to insufficient sleep. Investigators will conduct a controlled in-laboratory insufficient protocol where participants will sleep in the lab for one night with sleep timing based on their habitual insufficient sleep schedule. In the morning, plasma will be collected for metabolomics analyses and participants will complete an oral glucose tolerance test for insulin sensitivity analyses. Participants will then complete a 4 -week increased sleep duration intervention targeting the recommended 7 hours of sleep per night. Following this intervention participants will again sleep in the lab for one night on their new sleep schedule. In the morning, plasma will be collected for metabolomics analyses and participants will complete an oral glucose tolerance test for insulin sensitivity analyses. Investigators anticipate these findings will be the first step in developing biomarkers of impaired sleep under free-living sleep conditions, and to determine how such biomarkers relate to insulin sensitivity changes associated with sleep loss. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
