This sub-study uses Fitbits and sleep diaries to securely collect sleep data, allowing NHS3 to learn how sleep disturbances (e.g., sleep duration, quality and variability) may affect people’s health.
Participants who enroll in the study will be asked to wear a Fitbit and keep a sleep diary for 14 days.
For this study, we are inviting participants who have already provided biological samples as part of the Chronic Disease Biospecimen Collection (CDBC). By combining sleep data with biomarker data, researchers will be better able to investigate the role of sleep in cardiometabolic disease risk.
Your privacy is important to us. All Fitbit account data is encrypted while stored on the phone, awaiting upload, and in transit. Data is re-encrypted when stored on the study server. All data is stored with a unique study ID number, not with your name. Your data will only ever be used for research purposes. We have a Certificate of Confidentiality from the National Institutes of Health, which means we cannot be forced (for example by court order or subpoena) to disclose your health information or other identifying information from the research in any Federal, State or local civil, criminal, administrative, legislative, or other proceedings. All collected data are IP firewalled and password protected.
This study is funded by the National Heart, Lung, and Blood Institute.
