Harnessing Sleep/Circadian Rhythm Data as a Biomarker to Mitigate Health Risks

This project will involve recruitment of 100 adolescents from primary and specialty health
clinics. Participants will participate in 3 phases: screening/intake visit, sleep study, and
follow-up visit.

The 1-hour screening/intake visit will be conducted at the Duke ADHD clinic at 2608 Erwin
Road, Pavilion East, Suite 300, Durham, NC 27705. During the screening/intake visit,
participants and their parents will complete questionnaires regarding the adolescent's
psychiatric health. Participants' vitals (i.e., height, weight, resting heart rate, blood
pressure) will also be assessed and recorded.

Eligible participants will enter the 7-day sleep study, during which they will be asked to
wear an actigraph watch 24 hours/day, apply a EEG sleep recorder each night, and complete a
daily sleep diary.

Following the final night of the sleep study, participants and parents will be asked to
return for a follow-up visit and will complete questionnaires about the participants' sleep
over the past week.
