Aging is a multidimensional process involving psychosocial wellbeing, cognitive performance, and biological health that work together through various physiological systems. Stress derived from racist experiences can impact physiological systems through inflammatory responses. Biological aging via epigenetic clocks have demonstrated utility in predicting cognitive decline and dementia. In this study we aim to examine the role of incarceration as a structural determinant of adverse aging. Linear regression models estimated the associations of Black–White and Latine–White disparities in jail and prison incarceration during 1985–1994 and 1995–2005, as well as self-reported history of incarceration, with accelerated biological aging (based on GrimAge scores) for HRS participants racialized as Black, Latine, or White. Participants racialized as Latine living in counties with widening Black-White jail and prison disparities across periods have an accelerated GrimAge score 1-3 months higher than counterparts from the same group not living in such counties. Self-reported incarceration for all racialized groups yielded accelerating aging by a minimum 14 months (Black) and a maximum of 20 months (Latine). These results highlight carceral exposure at both the structural and individual levels as racialized structural determinants of health for mid-to-late life adults.
