摘要

Background

Although several studies have examined the Kidney Disease Quality of Life (KDQOL) in patients with chronic kidney disease (CKD), the factors associated with kidney-related symptoms have not been fully explored.

Methods

This nationwide multicenter cohort study enrolled 2248 patients. To identify the factors associated with each item or the three KDQOL domains, such as burden of kidney disease, symptoms/problems of kidney disease, and impact of kidney disease on daily life, multiple regression analysis was performed using baseline data.

Results

The study population had a mean age of 69.1 ± 12.6 years, comprised 64.7% men, and had mean estimated glomerular filtration rate (eGFR) of 23.2 ± 10.4 mL/min/1.73 m2. Mean serum creatinine levels were 1.4 ± 0.2, 2.3 ± 0.5, and 4.5 ± 1.5 mg/dL for G3b, G4, and G5, respectively. The mean scores in the three KDQOL domains among CKD stages showed significantly decreasing trends. Of all the 11 symptoms assessed, 6 had scores that significantly decreased as the CKD stage progressed and 9 had scores that significantly decreased as the age category group increased. Multiple regression analysis revealed eGFR as a significantly associated factor for 5 of 11 symptoms. Age, body mass index, and comorbidities were also detected as significant factors for some symptoms.

Conclusions

In addition to eGFR, several factors were associated with symptoms in patients with CKD. Nephrologists need to recognize renal dysfunction-specific symptoms and explore other plausible causes of nonspecific symptoms.
