Abstract
Subjective life expectancy subjectively refers to an individual's expectation of the possibility of survival in the future, and is not a simple subjective evaluation, but an important health indicator that allows people to make decisions, plan, and control their own behavior in relation to health promotion. This study analyzed data from the Korean Longitudinal Study of Aging (KLoSA) to determine whether frailty and oral health affect the subjective life expectancy of patients with arthritis aged 55 or older. In order to identify factors influencing the participants' subjective life expectancy, multiple linear regression was used to analyze the results. In the final model the subjective life expectancy decreased as age increase. Subjective life expectancy was higher in the case of having a spouse, high income, working, the better the subjective health status. Compared to healty participants, the subjective life expectancy was lower in the pre-frailty and the frailty. The higher the oral health, the higher the subjective life expectancy. Based on the results of this study, if the oral health is maintained positively and subjective life expectancy is increased by providing interventions to prevent frailty, arthritis patients will live healthier lives with high expectations regarding subjective life expectancy in a positive direction.
