A meta-analysis of 140 studies involving nearly 66,000 individuals found that lower socioeconomic status and exposure to discrimination are consistently associated with accelerated biological aging, as measured by epigenetic clocks. The association was strongest with newer-generation epigenetic measures and was evident from childhood through adulthood across 23 countries.
