Summary

Sleep and wakefulness disorders impact 50 to 70 million Americans and insufficient sleep is epidemic with over 50% of Americans reporting less than 7 hours of sleep per night. Health problems associated with insufficient sleep include inflammation, depression and anxiety, diabetes, stress, drug abuse, poor quality of life, obesity, and fatigue related accidents on the job/while driving. While the contribution of sleep to overall health, well-being, and public safety is recognized, no established clinical biomarkers of sleep deficiency exist. Such biomarkers would have utility as road-side biomarkers of sleepiness (e.g., drowsy driving), monitoring on the job fatigue/fitness for duty (e.g., transportation, military ops health care), monitoring sleep health, as well as for clinical diagnostics and measures of clinical treatment outcomes. Thus, investigators designed a controlled laboratory insufficient sleep protocol utilizing metabolomics to identify biomarkers of insufficient sleep. Investigators propose to identify changes in metabolites that consistently occur during insufficient sleep. As an exploratory outcome investigators will examine associated changes in metabolites and cognitive performance during insufficient sleep.

Detailed description

Impaired sleep affects millions of people each year representing an important public health issue. This project will utilize metabolomics approaches to identify biomarkers in the blood that respond consistently to insufficient sleep. The overall goal of this project is to use a discovery and targeted approach to identify specific small molecules in plasma as candidate biomarkers of insufficient sleep. Investigators will conduct a controlled in-laboratory insufficient sleep protocol where participants receive 2 days of 5 hour sleep opportunities per night on 2 separate occasions. Plasma will be collected for metabolomics analyses every 2 hours (across 24 hours) during scheduled wakefulness at baseline and during insufficient sleep. Participants will complete the insufficient sleep protocol twice, separated by 23 days of sufficient sleep, to identify which plasma metabolites consistently change during insufficient sleep. Investigators anticipate these findings will be the first step in establishing validated biomarkers of impaired sleep that will advance our understanding, assessment and management of health consequences and symptoms associated with insufficient sleep.
