Item Neighborhood racial income inequality and cognitive health(Wiley, 2024-06) Zahodne, Laura B.; Sol, Ketlyne; Scambray, Kiana; Lee, Ji Hyun; Palms, Jordan D.; Morris, Emily P.; Taylor, Lauren; Ku, Vivian; Lesniak, Mary; Melendez, Robert; Elliot, Michael R.; Clarke, Phillippa J.INTRODUCTION. Neighborhood socioeconomic status (SES) has been linked to dementia, but the distribution of SES within a neighborhood may also matter. METHODS. Data from 460 (47% Black, 46% White) older adults from the Michigan Cognitive Aging Project were linked to census tract–level data from the National Neighborhood Data Archive (NaNDA). Neighborhood SES included two composites reflecting disadvantage and affluence. Neighborhood racial income inequality was the ratio of median incomes for White versus Black residents. Generalized estimating equations examined associations between neighborhood factors and cognitive domains. RESULTS. Neighborhood racial income inequality was uniquely associated with worse cognitive health, and these associations did not differ by participant race. Neighborhood disadvantage was only associated with worse cognitive health among Black participants. DISCUSSION. Both the level and racial distribution of SES within a neighborhood may be relevant for dementia risk. Racial differences in the level and impact of neighborhood SES contribute to dementia inequalities.
