Abstract
Objective
To determine the association of socioeconomic disadvantage and parent-rated health in children with chronic kidney disease (CKD).
Methods
A total of 377 children (aged 6–18 years) with CKD stages I–V (n = 199), on dialysis (n = 43), or with a kidney transplant (n = 135) were recruited from 2012 to 2016 in Australia and New Zealand. Associations of five socioeconomic status (SES) components and the global SES index with parent-rated health of the child were examined using adjusted logistic regression.
Results
The median age of participants was 12.6 years (interquartile range (IQR) 8.9–15.5). In the entire cohort, the adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for poor parent-rated health were 1.85 (1.13–3.03) for lower household income, 1.78 (1.08–2.96) for families that did not own their own home, 2.50 (1.50–4.16) for caregivers who rated their financial status as poor, 0.84 (0.51–1.38) for lower educational attainment, and 1.68 (1.04–2.72) for children whose primary caregivers were unemployed. With reference to the highest global SES index quartile, adjusted ORs for poor parent-rated health in descending order were 1.49 (0.69–3.21), 2.11 (1.06–4.20), and 2.20 (1.09–4.46), respectively. The association between low SES and poor parent-rated health was modified by CKD stage, where lower global SES index was independently associated with poor parent-rated health in children with CKD stages I–V, but not children on dialysis or with kidney transplants (p = 0.04).
Conclusions
Low SES is associated with poor parent-rated health in children with CKD stages I–V, but not children on dialysis and with kidney transplants.
