The Long-Term Associations of Objective and Subjective Health Status on Mortality

Background: The aim of this study was to reveal the longitudinal associations of health status (HS) and Self -rated Health (SRH) on mortality. Methods: Data from the Korea Longitudinal Study of Ageing were used in this study. The baseline data (2006) included 10,239 participants. The Cox proportional hazard model was used to verify the hypothesis. Results: The mortality was high when the health status was Bad and higher when the SRH was Bad. The HS-Bad-SRH-Bad group had the highest mortality. Middle-aged people with diseases had higher mortality than older people who perceived themselves as in Bad health. For older people, mortality was high for SRH-Bad peo-ple of all health statuses. Conclusion: The results predict a high rate of mortality for middle-aged and older people with a combination of HS-Bad and SRH-Bad, with SRH being relatively more influential in mortality
