Fitbit, the leading global wearables brand, and the National Institutes of Health (NIH) have launched the Fitbit Bring-Your-Own-Device (BYOD) project, the first digital health technology initiative for the All of Us Research Program. Fitbit users currently enrolled in the program can now choose to sync their Fitbit accounts to help researchers unlock deeper insights into the relationships between health indicators such as physical activity, heart rate, sleep and health outcomes. By consenting to sync their data with All of Us, Fitbit users have the opportunity to contribute to one of the world’s largest precision medicine studies and help build one of the most diverse data sets for scientific research. Fitbit is the first wearable to be included in the program. (January 16, 2019)
