Abstract
Background: This study aimed to examine racial differences in biological aging indicators among Black and white women and to test whether life course socioeconomic status (SES) was associated with biological aging indicators among Black and white women.
Methods: Data were from 423 participants who self-identified as non-Hispanic Black (n = 217; Mean age = 39.5, range = 37-42) and non-Hispanic white (n = 206; Mean age = 39.6, range = 37-43) in the National Growth and Health Study (NGHS). We incorporated measures of SES across the life course, including parental education and household income, and participants' education and household income. We utilized the three frameworks of life course SES and health, including the sensitive period framework (i.e., direct association, childhood SES and biological aging), accumulation framework (i.e., the cumulative impact of SES across the life course on biological aging ), and SES mobility framework (i.e., the association between intergenerational educational mobility and biological aging). We included three indicators of biological aging, including GrimAge, telomere length, and CRP. We conducted within-race analyses to examine the association between life course SES and biological aging indicators. Results: Relative to white women, Black women in NGHS showed significantly older GrimAge and higher CRP. However, Black women showed longer telomere lengths. Within-race analyses indicated that lower parental education was only associated with higher CRP among Black women. Cumulative SES across the life course was associated with older GrimAge, shorter telomere length, and elevated CRP among Black women but not white women. Finally, upward educational mobility was associated with younger GrimAge among white women but not Black women.
Discussion: Due to the nonequivalence of life course SES between Black and white groups in the United States, intra-racial analysis is crucial to elucidate the complexity of the association between life course SES and indicators of biological aging within each racial group. We showed that cumulative socioeconomic disadvantage across the life course affects Black but not white women’s biological aging. In addition, we found evidence of a diminishing return of upward educational mobility among Black women.
