Abstract:
Social and racial disadvantages can lead to weathering, and the effects of social mobility and socioeconomic position (SEP) on weathering may vary depending on individuals' skin color. Based on data from 11,064 Brazilian adults form The Brazilian Longitudinal Study of Adults Health (ELSA-Brasil), we examined how racism, SEP, and intergenerational educational mobility shape weathering-defined as the difference between biological and chronological age. We demonstrated that individuals exposed to social disadvantages such as racism and low SEP exhibited greater weathering compared to socially advantaged individuals, suggesting an explanatory pathway for social and racial health inequities. Being in a higher SEP was not as advantageous for Black individuals as it was for White individuals. Upward social mobility was associated with lower weathering. These findings highlight how racism and socioeconomic adversity accumulate and interact to shape aging, revealing that social mobility may offer partial relief from the physiological impact of inequality.

An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...
