The Association between Subjective Age and Healthy Aging in Later Life: An Age-dependent Analysis

Abstract

The purpose of this study is to examine the relationship between subjective age (whether one subjectively perceives himself as ‘the elderly’ or ‘not the elderly’) and healthy aging. Using data from the 2014 National Elderly Survey (KIHASA), this study selected a total of 9,653 participants consisting of young-olds (aged 65-74) and old-olds (aged 75-84) For both the young-old and the old-old, multiple regression analyses were conducted to examine the research model. In the young-old population, one’s considering oneself as “non-elderly” was significantly associated with higher cognitive functioning, fewer chronic diseases, lower depressive symptoms, and higher level of social engagement. On the other hand, in the old-old population, one’s considering oneself as “non-elderly” was associated only with higher cognitive functioning, and not with the other domains of healthy aging. The findings suggest that subjective age can be considered as an important predictors of older adults’ healthy aging. These findings indicate that the association between subjective age and healthy aging has a different pattern depending on the age group.
