Factors affecting depression and health-related quality of life in the elderly during the COVID-19 pandemic.

Background: This study investigated changes in the health behaviors of the elderly due to coronavirus disease 2019 (COVID-19), concerns due to COVID-19, depression, and healthrelated quality of life (HRQOL), and aimed to identify factors that affect depression and HRQOL in the elderly.

Methods: This study was conducted using data from the 2021 Community Health Survey of the Korea Disease Control and Prevention Agency. From a total sample size of 229,242 individuals, 74,376 elderly people aged 65 or older were selected as subjects, and changes in health behaviors, concerns due to COVID-19, depression, and HRQOL were measured and analyzed.

Results: The level of depression associated with sleep and fatigue was high. The lowest HRQOL was related to physical pain and discomfort, while the most common concerns were related to economic difficulties. Factors influencing depression included worries about infection and economic harm, while factors impacting HRQOL encompassed concerns about infection, economic harm, and criticism from others.

Conclusion: If an infectious disease situation such as COVID-19 reoccurs in the future, it will be necessary to encourage participation in hybrid online and offline programs at senior welfare centers. This should also extend to community counseling institutions like mental health welfare centers. Additionally, establishing connections with stable senior job projects can help to mitigate the effects of social interaction restrictions, physical and psychological health issues, and economic difficulties experienced by the elderly.
