Differences in the Association of Neighborhood Environment With Physical Frailty Between Urban and Rural Older Adults: The Korean Frailty and Aging Cohort Study (KFACS)
Abstract
Objective: We examined the difference in the relationship between perceived neighborhood environments and physical frailty between urban and rural older adults.
Design: Cross-sectional study.
Setting and participants: Urban and rural community in South Korea; a total of 2593 community-dwelling older adults aged 70-84 years (mean age: 76.0 years, 51.0% women) in the Korean Frailty and Aging Cohort Study (KFACS).
Methods: The neighborhood environment was assessed using the 17-item Environmental Module of the International Physical Activity Questionnaire (IPAQ-E). The IPAQ-E had 7 environmental factors (residential density, access to destinations, neighborhood infrastructure, neighborhood safety, social environment, aesthetic qualities, and street connectivity). Physical frailty was defined using the Fried frailty criteria with modified cutoffs.
Results: The number of participants residing in urban and rural areas was 1902 and 691, respectively. The prevalence of frailty was 5.3% and 12.0% in urban and rural areas, respectively. In urban areas, frailty was associated with the total IPAQ-E score (β = -0.007, P = .009) after adjusting for confounding factors. There was no association in the rural areas (β = -0.003, P = .535). In urban older adults, logistic regression showed that absence of destination [odds ratio (OR) 2.58, 95% confidence interval (CI) 1.36-4.90] and no crime safety at night (OR 2.00, 95% CI 1.12-3.57) were associated with a higher risk of frailty. In rural older adults, poor access to recreational facilities (OR 2.17, 95% CI 1.07-4.40) and no aesthetics (OR 2.49, 95% CI 1.22-5.10) were associated with frailty.
Conclusions and implications: Our study indicated that the presence of destination and crime safety at night was significantly associated with physical frailty among older adults living in urban areas, whereas aesthetics and recreational facilities were significantly associated with physical frailty in rural older adults.
