The ABCD system has four domains: pathophysiology, body mass index classification, complications, and complication severity. This new framework aims to provide a more nuanced understanding of obesity as a chronic disease.
A large dataset of daily resting heart rates from wearables reveals significant individual variations, accounting for less than 10% of variation between people. The analysis also identifies seasonal trends and brief periods of abnormal heart rate.
