Background: Limited health literacy has been associated with adverse outcomes in children. We evaluated this association in the setting of chronic kidney disease (CKD).

Methods: We assessed the parental health literacy of 367 children enrolled in the Chronic Kidney Disease in Children (CKiD) Study, using the Short Test of Functional Health Literacy (STOFHLA). We evaluated the association between parental health literacy and CKD progression, defined as time to the composite event of renal replacement therapy (RRT, dialysis, or kidney transplant) or 50% decline in estimated glomerular filtration rate (eGFR).

Results: Median CKiD participant age was 9.5 years, 63% were male, and 59% non-Hispanic white. Median eGFR at baseline was 63 ml/min/1.73 m2, and median urine protein-to-creatinine ratio was 0.22. The median STOFHLA score was 98. Over a median follow-up of 3.7 years, the overall CKD progression rate was 2.8 per 100 person-years. After adjustment for demographic and clinical factors, the relative time to CKD progression was 28% longer per 1 SD increase in STOFHLA score (relative time, 95% CI, 1.28, 1.06-1.53).

Conclusions: In this cohort of children with CKD, higher parental health literacy was associated with a nearly 30% longer time to the composite CKD progression outcome.
