Health literacy of individuals undergoing dialysis therapy

Abstract

Objective: to assess the functional levels of health literacy in individuals undergoing dialysis. Method: a cross-sectional study with 42 patients of the Nephrology Unit of a public hospital in Recife, Brazil, from May to August 2016. Data were collected through scripted interviews and chart analysis. Functional health literacy was measured using the Brazilian version of the Short-Test of Functional Health Literacy in Adults questionnaire. Data analysis was performed using the Statistical Package for Social Sciences (SPSS®) software, version 18.0, with a univariate analysis to verify the association between independent variables and functional health literacy levels using Fisher’s exact test. Results: 80.9% of the patients presented inadequate health literacy and 19.1% presented adequate health literacy. The number of correct answers remained between 0-18 in the reading comprehension and in the scheduling appointment card. Among the independent variables, only marital status (p-value=0.018) and personal income (p-value=0.009) were factors associated with the worst scores in the test, indicating that these variables influence the increase in inadequate literacy. Conclusion: the prevalence of inadequate functional literacy was high, reflecting difficulties in understanding and processing health information, which may interfere with therapeutic management and self-care.
