Background
Research is needed to better understand the links between health literacy and kidney disease knowledge on patient self-care behaviors in order to guide interventions to improve self-care in chronic kidney disease (CKD).
Methods
Among study participants with CKD stage 1-5, validated surveys assessed level of health literacy (Rapid Estimate of Adult Literacy in Medicine [REALM]), perceived kidney disease knowledge (Perceived Kidney Knowledge Survey [PiKS]), objective kidney disease knowledge (Kidney Disease Knowledge Survey [KiKS]), and self-care behaviors (modified Summary of Diabetes Self-Care Activities Assessment [SDSCA]). A summary score of self-care was constructed utilizing the SDSCA scoring system. Multivariable adjusted linear regression estimated the association of self-care scores with health literacy (inadequate vs. adequate, determined by REALM score ≤59 vs. >59, respectively) and PiKS and KiKS scores (per SD). Health literacy was also explored as a potential effect modifier.
Results
Of the 401 participants: mean age was 57 years; 47% female, 38% diabetes; 77% CKD stage 3-5. The prevalence of inadequate health literacy was 18%. The median KiKS score (range 0-1) was 0.7 (interquartile range [IQR] 0.6-0.8), and median PiKS score (range 0-4) was 2.6 (IQR 2.1-3.0). After full adjustment, a PiKS score was positively associated with self-care scores (β=1.0, 95% confidence interval: 0.3-1.7). Health literacy and KiKS scores were not associated with self-care. There was evidence of effect modification by health literacy; a KiKS score appeared to positively associate with self-care scores only among those with inadequate literacy, but this did not reach statistical significance (Figure).
Conclusion
Objective kidney knowledge is likely necessary, but not sufficient for self-care, and may be particularly helpful to those with inadequate health literacy. Perceived kidney knowledge has a strong positive association with self-care, offering a novel target to support self-care among patients with non-dialysis dependent CKD.
