A wearable device’s aging measure is linked to health and behavior
Updated
Abstract
Essence
A wrist-worn photoplethysmography aging clock was linked to disease burden, health behaviors, pregnancy, and some cardiac events in daily life.
Evidence
An observational analysis of 213,593 participants in the Apple Heart & Movement Study using more than 149 million participant-days found that elevated gap tracked higher diagnosis rates of heart disease, heart failure, and diabetes and predicted incident heart disease events after risk-factor adjustment.
Caveat
Because the study is observational and based on a consumer wearable cohort, the associations do not show that the aging clock causes or independently explains these health outcomes.
