Abstract

The aim of this study was to compare mortality and chronic disease prevalence in people with psychiatric disease and the general population, and to find out which chronic diseases increase the risk of all-cause mortality, especially in people with psychiatric disease. In this study, he evaluated data from his 2019 sample of his cohort from his 2002 health examination of the Korean National Health Insurance Agency. The results showed that people with mental illness had higher all-cause mortality than those without mental illness (11.40% vs. 10.28%, p=0.0022). Several chronic diseases have a higher prevalence and risk of all-cause mortality in individuals with mental illness than in the general population. Among people with the same chronic disease, those with psychiatric disorders had a higher risk of all-cause mortality: cancer (aHR 2.55, 95% CI 2.488-2.614), liver cirrhosis (aHR 2.198, 95% CI 2.086-2.316). ), and arrhythmias (aHR 1.427, 95% CI 1.383-1.472) were the three most common chronic diseases that increase risk. Increased allcause mortality in people with mental illness compared to people without mental illness. Our results suggest that more attention should be paid to chronic illness in people with mental illness in clinical practice by explaining the impact of chronic illness on all-cause mortality in people with mental illness.
