The purpose of the HD-SLEEP2 study is to help researchers understand sleep in African Americans. The investigators also want to know what factors may affect sleep.
African Americans who self-report poor sleep (n=80) will be invited to complete questionnaire based self-assessment of known factors and comorbidities contributing to alterations in sleep such as demographic characteristics, anthropometrics, depression, insomnia, and food habits in conjunction with objective and subjective measures of sleep via 7-day accelerometry (sleep duration), overnight oximetry (sleep apnea), and sleep questionnaires.
Study Type
OBSERVATIONAL
Enrollment
80
Eligible participants will be invited to fill out several forms and wear a watch-like device on their wrist (an accelerometer) for 7 days to assess their sleep habits. They will also be asked to sleep at home with a watch-like device attached to a sleeve which covers their index finger (an oximeter) for one night to assess whether they may have a sleep problem like sleep apnea.
