Abstract:
Objective:To investigate the association between self-rated health status and mortality risk, and to evaluate the predictive value of self-rated health status for mortality risk among the elderly.
Methods:Based on the China Health and Retirement Longitudinal Study (CHARLS) database, data of sociodemographic information, self-rated health status and mortality of the elderly aged 60 years and older were collected from 2011 to 2018. The association between self-rated health status and mortality risk among the elderly was analyzed using a multivariable Cox proportional risk regression model.
Results:Totally 4 850 individuals were included, with an median age of 65 (interquartile range, 8) years. There were 2 485 males (51.24%) and 2 365 females (48.76%). There were 877 individuals (18.08%) rated their health as good, 2 078 individuals (42.85%) as general, 1 895 individuals (39.07%) as poor. A total of 28 955 person-years were followed up, with an average follow-up of 5.97 years per person. There were 855 deaths by the end of follow-up in 2018, and the median survival time was 7 (interquartile range, 3) years. Multivariable Cox proportional risk regression analysis showed that there were interactive effects of age, sex and self-rated health status on mortality, respectively (both P<0.05). The results of gender-stratified analysis showed that there was no significant association between self-rated health status and mortality risk in old women (P>0.05). The mortality risk was higher in old men with poor self-rated health than with good self-rated health (<70 years, HR=5.382, 95%CI: 3.263-8.876; 70 to 79 years, HR=3.536, 95%CI: 1.070-11.686; ≥80 years, HR=3.043, 95%CI: 1.827-5.066).
Conclusion:There is an association between self-rated health status and mortality risk among the elderly, the old men with poor self-rated health had a higher mortality risk.
