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.

Detailed Description

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.

| --- | --- |
| African American adults with poor sleep<br>Individuals with self-identified poor sleep quality and/or quantity | Combination Product: Assessment of sleep and related factors<br>* 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.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Habitual sleep duration | Average hours of sleep/24h period | 7 days | 
| Oxygen desaturation index | Number of oxygen desaturation events per hour of sleep | 1 day | 
| Sleep Quality | Sleep quality as determined by Pittsburgh Sleep Quality Index. The minimum score is 0 and maximum score is 21. Higher scores indicate poor sleep quality. | 1 day | 
| Daytime Sleepiness | Severity of daytime sleepiness as determined by Epworth Sleepiness scale. The minimum score is 0 and maximum score is 24. Higher scores suggest daytime sleepiness. | 1 day | 
| Sleep behaviors | Sleep hygiene behaviors as determined by sleep hygiene index. The minimum score is 13 and maximum score is 65. Higher scores indicate poor sleep hygiene status. | 1 day |
