Good subjective health status and health-related quality of life in people with chronic kidney disease: A secondary analysis using the Korea National Health and Nutritional Examination Survey in 2019 and 2020

Abstract

Purpose: This cross-sectional study aimed to describe subjective health status of people with chronic kidney disease (CKD), identify factors that affect good subjective health status and investigate the relationship between good subjective health status and health-related quality of life (HRQOL) in people with CKD.Methods: This secondary analysis utilized data from the Korean National Health and Nutrition Examination Survey in 2019-2020. Participants (<italic>N</italic>=295) had an eGFR of ≤59 mL/min/1.73 m². Descriptive and inferential statistics were used to analyze the data. Univariate and multivariate logistic regression analyses were performed to identify factors affecting good subjective health status and examine the association between good subjective health status and HRQOL.Results: Among all participants, 61.4% had good subjective health status, and the HRQOL index was 0.88 in people with CKD. Household income, activity limitation, stress, and the number of comorbidities in people with CKD were associated with good subjective health status. People with better subjective health status were more likely to be satisfied with self-care, usual activities, and pain/discomfort in HRQOL.Conclusion: Good subjective health status is associated with better HRQOL. Therefore, subjective health status should be assessed early, and a nursing intervention program should be developed considering factors that can improve subjective health status in people with CKD.
