Healthy volunteers and people with prediabetes needed for a research study!

Johns Hopkins Sleep Disorders Center & the National Institutes of Health

JHU IRB#00301239
NIH IRB#000911
Clinicaltrials.gov NCT05745441

  • We are researching what happens to your body’s sugar levels and metabolism when you eat a “late” dinner, compared to when you eat an “early” dinner. The “early” and “late” dinner times will be customized to your body’s internal circadian clock. The study requires 1 visit to the Johns Hopkins Clinical Research Unit (Baltimore, MD) and 2 visits to the National Institutes of Health (Bethesda, MD). Meals will be provided. A sleep study and blood work will also be involved.

    You will be paid up to $1400 for completing the study and an additional $100 bonus for keeping all scheduled visits.

    To participate, you must:

    • Be 18-50 years old
    • Have a regular bedtime before 1am
    • NOT have any sleep disorder (insomnia, restless leg syndrome, etc.). Sleep apnea is allowed if you regularly use your CPAP machine.
    • NOT take medications that can affect your sleep
    • NOT smoke
    • NOT be pregnant or breast feeding

    To find out if you are eligible, please fill out this questionnaire
