Representativeness and bias of neighborhood‐level determinants in UBRAIN: a multi‐site Aging and Dementia cohort

Our analysis of the UBRAIN cohort reveals a significant spatial and socioeconomic bias, with participants disproportionately residing in neighborhoods with few low-skilled workers, high employment rates, and a highly educated population. These differences in representativeness should be taken into account when interpreting results from such cohorts, especially in the context of urban and social determinants of health. Efforts should be made to include participants from neighborhoods with lower socioeconomic status.

Abstract

Our analysis of the UBRAIN cohort reveals a significant spatial and socioeconomic bias, with participants disproportionately residing in neighborhoods with few low-skilled workers, high employment rates, and a highly educated population. These differences in representativeness should be taken into account when interpreting results from such cohorts, especially in the context of urban and social determinants of health. Efforts should be made to include participants from neighborhoods with lower socioeconomic status.
