Neighborhood Impacts of Cognitive Health and Dementia Disparities

Understanding the impacts of neighborhood factors for cognitive health and dementia disparities within a Multi-Ethnic Cohort

Summary

This project leverages and extends novel longitudinal neighborhood and cognition data from the Multi-Ethnic Study of Atherosclerosis (MESA). It addresses major research gaps by identifying unique patterns of neighborhood change related to the causes of prevalence and disparities in cognitive decline and dementia. This work facilitates actionable community and clinical interventions to address and remediate racial and socioeconomic inequalities derived from the unequal distribution of environmental supports for healthy aging.

Partners

Multi Ethnic Study of Atherosclerosis Coordinating Center at University of Washington; MESA field centers; MESA MIND Ancillary Study.

Research Methods

This project will undertake large-scale collection, processing, and distribution of new neighborhood data within MESA. The main objective is to identify unique patterns of neighborhood change related to the causes of prevalence and disparities in cognitive decline and dementia. The main objective will be attained by (Aim 1) characterizing dynamic, longitudinal neighborhood social and built environment variables (survey-based and GIS-derived) relevant to cognition for residential addresses of a MESA; (Aim 2) examining associations of neighborhood environmental characteristics with cognition and clinically relevant ADRD outcomes; (Aim 3) investigate determinants of disparities in ADRD outcomes by socioeconomic position and race/ethnicity and assess the contribution of neighborhood environments.
