ABSTRACT
Health literacy (HL) encompasses an individual's ability to access, understand, and integrate health-related information. Routine use of functional, critical, and communicative HL screening questionnaires shows promise in identifying those at risk for poor clinical outcomes. Although it is evident that low levels of HL are associated with poor clinical outcomes in end-stage renal disease, it is unclear how varying HL levels are associated with nutrition-specific adherence. Here, we present a summary of literature published between 2018 and 2023 examining relationships between HL and nutrition-related adherence among individuals on hemodialysis. A positive association between higher HL scores and adherence to nutrition-related recommendations was found in this population. Based on these findings, screening for low levels of HL using validated tools should be integrated into standard practice for nutrition assessment. Future studies are warranted to explore the dietitian's role in improving HL and to develop a standardized measure for nutrition-related adherence.
