Depression and quality of life in older adults with pneumoconiosis: The mediating role of death anxiety

Abstract

This study identified factors related to the quality of life of older adults with coal workers’ pneumoconiosis and determined the mediating effect of death anxiety on the relationship between depression and quality of life. The participants were 161 older adults who were admitted to five pneumoconiosis hospitals in South Korea. The results showed that higher levels of depression indicated higher levels of death anxiety, and higher levels of depression and death anxiety indicated poorer quality of life. While controlling for general characteristics, death anxiety (β = 0.47, P < .001) had a complete mediating effect on the relationship between depression (β = 0.13, P = .075) and quality of life (R2 = 0.70, Adjusted R2 = 0.68, P < .001). To improve the quality of life of older adults with pneumoconiosis, interventions that reduce death anxiety along with depression should be investigated.
