Children with CKD suffer from reduced HR-QOL. The extent of impairment and risk factors for poorer HR-QOL and disability are under-studied. The study aimed to compare overall HR-QOL and severity of disability in children and adolescents with different stages of CKD and to determine factors associated with lower HR-QOL scores.


HR-QOL data were collected from children and adolescents (age 6-18 years) across five paediatric units in Australia and New Zealand. The Health Utilities Index 3 survey was used to measure overall utility based HR-QOL (where 0 represents being dead and 1 represents full health). A score of 1.00 represents no disability, 0.89-0.99 represents mild disability, 0.70-0.88 represents moderate disability and less than 0.70 represents severe disability. HR-QOL scores and disability stages were compared between CKD stages using the Mann-Whitney-U test. Multivariable linear regression assessed factors associated with decline in HR-QOL.


There were 377 children with CKD (median age 12.6 years). The median unadjusted HR-QOL score for those with CKD stages 1-4 was 0.88 (interquartile range [IQR] 0.61-0.97), higher than those on dialysis (0.67, IQR 0.39-0.91, p<0.001), but similar to kidney transplant recipients (0.83, IQR 0.59-0.97, p=0.4). Severe disability was more common in dialysis patients (20/35, 57%), compared to transplant recipients (37/114, 33%) or those with CKD stages 1-4 (57/176, 32%) (c2=8.4, p=0.02) (table 1). The factors associated with decrements in HR-QOL were being on dialysis (compared to CKD stages 1-4: reduction by 0.13, 95%CI 0.02-0.24) and lowest quartile family income (compared to highest income quartile: reduction by 0.10, 95%CI 0.01-0.20), when adjusted for age and gender.


HR-QOL children with CKD was significantly related to stage of disease and family income, with children on dialysis and those the lowest family income having significant lower HR QOL.
