Abstract

The purpose of this study was to provide an understanding of the trajectories of multidimensional health among older adults, including depression, chronic diseases, and cognitive function. Data were drawn from the 1-6 waves of the Korean Longitudinal Study of Ageing(KLoSA), and a sample of 2,059 respondents aged 65 and older at baseline was used for the analyses. Latent growth curve models and growth mixture models were used to explore the changes in depression, chronic diseases, cognitive function, and heterogeneous trajectories among them. One-way ANOVAs with Scheffé post-hoc analysis and chi-square tests were used to find differences in sociodemographic characteristics, health behaviors, and life satisfaction across the latent trajectory classes. Latent growth curve models revealed that depressive symptoms and the number of chronic diseases increased over time, while cognitive function showed gradual decreases. Three heterogeneous patterns of multidimensional health trajectories were identified: normal aging, increase in chronic diseases, and chronic deterioration. Significant differences were observed in sociodemographic characteristics, health behaviors, and life satisfaction across the three latent classes. In particular, low educational attainment, household income, and life satisfaction were associated with the chronic deterioration class. Based on the findings, we discussed suggestions for health promotion education targeting older adults. This study also emphasizes the importance of home economics education in promoting health literacy across the life course.

본 연구는 고령화연구패널조사(KLoSA)의 1-6차 연도 자료를 분석하여 노년기의 우울, 만성질환, 인지기능의 다중적 측면에서의 건강 변화 유형을 파악하고 이와 관련이 있는 요인들을 분석하고자 하였다. 연구의 대상은 1차 연도 조사 시점에서 65세 이상이고 결측률이 없는 총 2,059명이다. 잠재성장모형을 통해 세 가지 건강 측면이 시간에 따라 어떠한 변화궤적을 보이는지 살펴보았으며, 성장혼합모형을 활용해 세 건강 요인에서 서로 다른 변화 궤적을 보이는 집단들을 유형화하였다. 또한 일원분산분석 및 Scheffé 사후검증, 교차분석을 통해 건강 변화유형 집단에 따라 인구사회학적 특성, 건강행동, 삶의 만족도에서 차이가 나타나는지를 살펴보았다. 본 연구의 주요 결과는 다음과 같다. 첫째, 잠재성장모형 분석 결과 우울과 만성질환의 수는 연령에 따라 점차 증가하고 인지기능은 점차 감소했다. 둘째, 성장혼합모형을 분석한 결과 노인의 건강 변화는 일반적 노화, 질환 증가, 만성적 문제의 세 집단으로 유형화되었다. 셋째, 노인의 인구사회학적 특성, 건강행동, 삶의 만족도는 세 집단에 따라 유의한 차이가 나타났다. 특히 만성적 문제 집단의 경우 교육 및 소득수준이 낮고, 전반적으로 낮은 삶의 만족도를 나타냈다. 본 연구는 노년기 건강증진 교육 프로그램에 있어 노인들이 경험하는 건강의 다중적 측면을 고려하는 것이 중요함을 보여주며, 노년기 건강증진 교육 프로그램을 위한 제언을 제공한다. 또한 전생애적 건강관리를 위한 건강정보문해력 증진에 있어서 가정과 교과과정이 갖는 중요성에 대해 논의하고자 한다.
