Wealth, Racism and the Pace of Aging Revealed by Epigenetic Clocks
TL;DR Summary
A cross‑country study of 66,000 people finds that lower socioeconomic status and racial marginalization are tied to faster biological aging, as measured by newer epigenetic clocks that track health and mortality risk; the strongest effects appear with the latest clocks, and children in poorer conditions also show accelerated aging, highlighting how poverty and discrimination shape aging and could guide targeted health interventions—though pediatric clock estimates are less certain due to developmental factors.
