Rural versus Urban Residence in Adulthood and Incident Cognitive Impairment.

ABSTRACT:

Introduction

Rural versus urban living is a social determinant of cognitive health. We estimated the association of rural versus urban residence in the USA with incident cognitive impairment (ICI) and assessed effect heterogeneity by sociodemographic, behavioral, and clinical factors.

Methods

The Reasons for Geographic and Racial Differences in Stroke Study (REGARDS) is a population-based prospective observational cohort of 30,239 adults, 57% female, 36% Black, aged 45+ years, sampled from 48 contiguous states in the USA in 2003-2007. We analyzed 20,878 participants who at baseline were cognitively intact with no history of stroke and had ICI assessed on average 9.4 years later. We classified participants' home addresses at baseline as urban (population ≥50,000), large rural
