Cardiometabolic Risk of Shiftwork

Cardiometabolic Risk of ShiftWork: Sleep Loss vs.Circadian Disruption

• Status: Terminated
• Phase: —
• Study type: Observational
• Enrollment: 64 (actual)
• Sponsor: University of Chicago · Academic / Other
• Sex: All
• Age: 18 Years – 50 Years
• Healthy volunteers: Accepted

Summary

The overall goal of the present application is to test the hypothesis that shift workers, who are chronically exposed to circadian misalignment and sleep loss, have a higher cardio-metabolic risk than day workers, and that the accumulated sleep debt and the degree of circadian misalignment both predict their elevated cardio-metabolic risk.

Conditions

• Sleep Deprivation
• Circadian Dysregulation
• Shift-Work Sleep Disorder

Interventions

Type	Name	Description
BEHAVIORAL	sleep extension & circadian alignment	Both groups of workers will undergo a 1-week period of fixed bedtimes, light-dark cycles and mealtimes in the laboratory to pay the sleep debt and align the circadian system
