Background
The goal of this study was to evaluate the quality of life (QOL) of Asian children with pre-dialysis chronic kidney disease (CKD) and to reveal the factors influencing the QOL of children with CKD.
Methods
We performed a cross-sectional study of the PedsQL 4.0 Generic Core Scale Module in the KNOW-PedCKD (KoreaN cohort study for Outcome in patients with Pediatric Chronic Kidney Disease) cohort, and compared the child self-reported and parent proxy-reported QOL of the pediatric cohort. From 2011 through 2016, a total of 376 children with CKD were enrolled after informed consent was obtained from parents or caregivers in seven pediatric nephrology centers.
Results
In parent proxy-reports, male patients had a better QOL than female patients in the Physical Functioning category. In child self-reports, male patients had better QOL than female patients in the Physical, Emotional, and School Functioning categories. According to CKD stage, there were significant differences in the QOL score in all categories of parent proxy-reports, and patients with higher CKD stage (lower glomerular filtration rate) had a worse QOL. Growth parameters showed a significantly positive correlation with the QOL score in all categories.
Conclusions
The QOL of children with predialysis CKD is affected by various factors, including sex, glomerular filtration rate (GFR), socio-economic status, existence of co-morbidities, anemia, growth retardation, and behavioral disorders. To improve their QOL, it is important to objectively understand the respective effects of these factors and attempt early intervention.
