We examined whether several established indices of epigenetic aging mediated the association between life course socioeconomic status (SES) and decrements in kidney function across a decade. Biomarker data were from 252 non-Hispanic (NH) Black and white participants who had consented to genetic analyses in Wave 2 (2004– 2009) and 3 (2014–2021) of the Midlife in the United States study (MIDUS) . Life course SES included parental education, a proxy of early life SES, and a composite score of adult SES based on the highest  \nSupplementary Information The online version contains supplementary material available at [https://doi](https://doi). org/10.1007/s11357-025-01728-0.  \nA.

We included five measures of epigenetic age accelerations (EAA), based on the residuals after each epigenetic clock was regressed on chronological age (Horvath, Horvath blood and skin, Hannum, PhenoAge, and GrimAge) and one measure of the pace of aging (DunedinPACE) obtained during MIDUS 2. Kidney function was based on serum creatinine–based estimated glomerular filtration rate (eGFR), calculated using the CKD-EPI formula (without race adjustment) . We calculated absolute decrements in eGFR across 11 years between MIDUS waves 2 and 3. Analyses were adjusted for age, sex, and health-related covariates (currently smoking,  \nD. M.

Lower adult SES and accelerated epigenetic aging, especially accelerated GrimAge and faster DunedinPACE pace of aging, mediated the association between lower parental education and larger decrements ineGFR. Accelerated epigenetic aging is associated with larger decrements in kidney function across a decade and may be one of the critical explanatory pathways for the higher burden of chronic kidney disease (CKD) among lower SES individuals.  \nKeywords Epigenetic aging · Geroscience · EGFR · Renal aging · Socioeconomic status  \nIntroduction  \nSocioeconomic inequality and systemic racism are known to be fundamental causes of health disparities in the USA [1, 2], including chronic kidney disease (CKD), an umbrella term for various disorders that are associated with a progressive decrement in kidney function.
