Association between health literacy and self-care behaviors among patients with chronic kidney disease.

ABSTRACT: BACKGROUND:We explored the association between health literacy and self-care behaviors among low-income patients with chronic kidney disease (CKD). METHODS:We used baseline data from the Kidney Awareness Registry and Education trial (n?=?137 patients with CKD) and multivariable logistic regressions to cross-sectionally examine the association between health literacy, defined by a validated questionnaire, and healthy behaviors. RESULTS:Study participants had a mean age of 55 years, were racially diverse (6% White, 36% Hispanic, 43% Black, 15% Asian) and 26% had low health literacy. Over one-third (38%) had hypertension, 51% had diabetes, and 67% had CKD stage 3 or 4. Compared to individuals with adequate health literacy, those with low health literacy had non-statistically significant higher tobacco use (adjusted odds ratio [aOR]?=?2.33; 95% CI 0.90-6.06) and lower consumption of sugary beverages (aOR?=?0.50; 0.20-1.23) and statistically significant decreased fast food intake (aOR?=?0.38; 0.16-0.93). Health literacy was not associated with differences in medication adherence (0.84; 0.38-1.89) or physical activity (aOR?=?2.39; 0.54-10.53). CONCLUSIONS:Health literacy was not uniformly associated with all self-care behaviors important for CKD management. A more nuanced understanding of the association of health literacy and self-care may be necessary to promote participation in behaviors known to slow CKD progression.
