Predictors of subjective age in community-dwelling older adults in Korea.

Subjective age, or felt age, is highly related to one's actual health and survival. This study was conducted to explore subjective age in community-dwelling older adults in Korea, and to identify predictors of subjective age. Participants were 616 Korean older adults who were living in the community. A multiple regression analysis with a stepwise method was conducted to analyse subjective age. On average, the participants felt 7.8 per cent younger than their actual age. A multiple regression analysis revealed that less severe depression, having better perceived health, having no visual impairment, having higher handgrip strength, and living in a metropolitan area were associated with younger subjective age. Further studies are needed to determine the factors associated with subjective age in older adults. Based on this study, conceptual analyses of subjective age or longitudinal studies to determine the factors affecting subjective age are advisable.
