Biological Age Associates with Longitudinal Frailty-Related Functional Decline: The Health and Retirement Study
Abstract Epigenetic clocks have emerged as markers of biological aging. Understanding their association with age-related functional decline may provide insights into DNA-mediated mechanisms underlying frailty-related functional decline and reveal which clocks best associate with accelerated functional decline. We therefore examined associations between established epigenetic clock measures and longitudinal trajectories of cognitive function, grip strength, and walking speed. We analyzed data from 4,018 participants …
