지역사회 거주 노인의 활동적 노화 지수와 신체 기능의 관련성: 2020 노인실태조사 자료 활용

Abstract

Purpose: This study investigated the impact of the Active Aging Index (AAI) on the physical function of older adults living in the community. Methods: We utilized data from the 2020 National Survey of Older Koreans and employed complex sampling. The physical function, involving mobility and self-care, was measured using the validated Physical Functioning Assessment of Community-Dwelling Older Persons. The AAI, which comprises 4 domains (i.e., employment, participation in society, independent, healthy and secure living, and capacity and enabling environment for active aging), and total scores were entered as the explanatory variables. Multiple regressions were performed by a complex sampling design. Results: In model 1, after controlling for covariates, the total AAI was significantly related to the physical function of older adults (B=18.63, p<.001). In model 2, significant associations were found between three out of four domains of the AAI and physical function. Specifically, employment (B=2.56, p<.001), independent, healthy and secure living (B=2.37, p=.036), and capacity and enabling environment for active aging (B=15.89, p<.001) were significant. Conclusion: Active aging could lead to improved physical function among older adults living in the community. Therefore, policymakers should consider active aging when promoting the physical function of these individuals.
