Lifecourse Socioeconomic Status and Cognitive Performance Among Midlife Latina Women in a California Agricultural Region.

Studies rigorously evaluating the relationship between time-varying lifecourse socio-economic status (SES) and cognitive aging primarily focus on non-Hispanic White adults with relatively high SES. We used data from the CHAMACOS Maternal Cognition Study (2022-2024), which included middle-aged, primarily Latina women who experienced relatively low lifecourse SES (n = 519). Participants provided information on early childhood (parental education), mid to late childhood (respondent education), and midlife SES (current poverty level), and completed the SOL-INCA neurocognitive assessment, yielding global and domain-specific cognitive performance z-scores.
