A meta-analysis of 140 studies with over 65,000 individuals evaluated different epigenetic clocks in relation to ethnicity and socioeconomic status. Newer epigenetic clocks yielded stronger associations between measures of marginalization and biological aging. Epigenetic markers of biological aging showed up in children of families with low socioeconomic status, and these persisted into adulthood.

Social determinants of health and epigenetic clocks: a systematic review and meta-analysis of 140 studies - Nature Human Behaviour
This meta-analysis of 140 studies (~66,000 participants) finds that social inequality is associated with faster biological ageing, with stronger associations observed for newer DNA methylation epigenetic clocks than earlier generations.
