“…The NVeADRC is actively enrolling community-dwelling adults over the age of 50, who maintain a primary and current residence in a non-metropolitan area in the broader Desert Southwest Region (DSR) surrounding Las Vegas, Nevada. For purposes of this study, determinations of geographic eligibility were made using the Rural Urban Commuting Area (RUCA) codes published by the United States Department of Agriculture (USDA) (USDA ERS, 2020 ), which are frequently used in rural health research (Hart et al, 2005 ; Danek et al, 2022 ; Shora et al, 2023 ). Each individual's primary residence was assigned a RUCA code based on the full 5-digit zip code, with RUCA codes ≥ 4 considered rural.…”

IntroductionRural-dwelling older adults face unique health challenges that may increase risk for Alzheimer's disease and dementia but are underrepresented in aging research. Here, we present an initial characterization of a rural community cohort compared to an urban cohort from the same region.MethodsAdults over age 50 living in a non-metropolitan area are clinically characterized using the Uniform Data Set, enriched with additional measures of verbal and non-verbal memory measures. Neighborhood disadvantage is also assessed. Clinical and cognitive differences between cohorts were explored after stratifying by cognitive impairment.ResultsBetween group comparisons found that rural-dwellers demonstrated better verbal memory than urban-dwellers on primary indices of learning, recall, and recognition, with small to medium effects in overall comparisons. When stratified by impairment, rural-urban differences were notably larger among cognitively normal individuals. Within-group comparisons found that the magnitude of impairment between cognitively normal and impaired groups was greater among rural-dwellers compared to urban-dwellers. No differences in non-verbal memory or overall clinical status were found, and there were no effects of neighborhood disadvantage on any cognitive measure.DiscussionLiving in a rural community presents a complex set of contextual factors that for some, may increase risk for dementia. In this study, we found small to moderate memory advantages for rural-dwellers, leaving open the possibility that late-life rural living may be advantageous for some and promote resilience. Additional prospective research is critically needed to better understand the factors that influence aging outcomes in this underrepresented population.
