Factors Affecting the Health-related Quality of Life of Older Adults with Unmet Healthcare Needs Based on the 2018 Korean National Health and Nutrition Examination Survey: A Cross-Sectional Study

Abstract

Purpose: This study aimed to identify the factors influencing the health-related quality of life (HRQoL) of older adults with unmet healthcare needs. Methods: Data from the 2018 Korean National Health and Nutrition Examination Survey were used. From a pool of 7992 participants, a final sample of 153 participants was analyzed using complex descriptive statistics, independent t-test, and multiple regression analysis. Results: In general, young age, being married, employment, higher income, no hypertension, health insurance coverage as an employee, and living with someone were associated with higher the HRQoL. The following factors were significantly associated with lower HRQoL scores: activity restriction (B=-0.15, p<.001), poor perceived health status (B=-0.14, p<.001), and higher depressive symptom score (B=-0.01, p=.002). The explanatory power was approximately 58%, and the model was deemed suitable (Wald F=16.86, p<.001). Conclusion: This study provides insights into the influence of various characteristics of older adults with unmet healthcare needs on their HRQoL. Healthcare providers should develop strategies to reduce these unmet healthcare needs.
