노인의 건강노화지수와 주관적 건강수준과의 관련성

Abstract

= Abstract = Objectives: This study examined the association between the Healthy Aging Index (HAI) and self-rated health among older Korean adults using nationally representative community data. Methods: Data were obtained from the 2024 Korea Community Health Survey, and 83,410 adults aged ≥65 years with complete information on HAI components and self-rated health were included. The HAI was calculated as the sum of five domains—physiological function, physical function, cognitive function, mental health, and social well-being (0–3 points each; total 0–15, higher scores indicating healthier aging). Self-rated health was assessed with a single item and dichotomized into good (very good/good) and not good (fair/poor/very poor). Complex sample t-tests and chi-square tests were used to compare HAI scores and characteristics by self-rated health, and hierarchical multiple logistic regression was performed to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for good self-rated health by HAI scores. Results: The mean(±standard error) total HAI score was 10.53(±0.015) out of 15.00, and 26.3% of participants reported good self-rated health. Those with good self-rated health had a significantly higher mean HAI score than those with not good health (12.37±0.016 vs. 9.88±0.017, p<0.001). In the fully adjusted model, a higher total HAI score was associated with higher odds of good self-rated health (OR=1.55, 95% CI=1.53–1.57), and all five domains showed significant positive associations, with mental health showing the strongest relationship. Conclusion: The HAI was significantly associated with good self-rated health among community-dwelling older Korean adults. Multidimensional strategies that address physical, physiological, cognitive, mental, and social aspects are needed to promote healthy aging and improve perceived health in the rapidly aging Korean society.
