Black Americans’ biological aging accelerates faster from accumulated stress exposure
Evidence
Geronimus, Arline T., Margaret Hicken, Danya Keene, and John Bound. “‘Weathering’ and Age Patterns of Allostatic Load Scores Among Blacks and Whites in the United States.” American Journal of Public Health 96, no. 5 (2006): 826–833. doi:10.2105/AJPH.2004.060749. The foundational empirical paper in the weathering research program, documenting differential patterns of biological aging — measured through allostatic load composite scores across cardiovascular, metabolic, immune, and neuroendocrine biomarker domains — between Black and white Americans across age groups in nationally representative data. Geronimus and colleagues found that Black Americans’ allostatic load scores showed steeper age-related increase than white Americans’, consistent with accelerated biological aging driven by cumulative stress exposure — the weathering hypothesis. — , The Rod and the Child, 7133
