Background: Non-adherence of hemodialysis patients to their recommended diet, and limitations on fluid intake, leads to the production of toxic substances and metabolites in the bloodstream, which can increase the risk of mortality in these patients. This study evaluated the adherence to dietary and liquid intake recommendations in hemodialysis patients.
Methods: One hundred and four hemodialysis patients were evaluated for dietary intake and adherence to dietary recommendations. Their diatary practice was evaluated using a 95-item food frequency questionnaire, and the Dialysis Diet and Fluid Nonadherence Questionnaire (DDFQ) questionnaire was used to assess non-adherence to dietary and fluind intake reommendations. The amount of weight gain between two sessions of dialysis and biochemical parameters of the patients was also measured. Statistical analysis was performend using SPSS version 22.
Results: Approximately 21.8% and 34.7% of patients did notadhere to their diet and of fluid intake recommendations. The rate of non-adherence to fluid intake recommendations were higher than the dietary recommendations. Protein intake of the patients was at an expected level, but their potassium intake was higher than the requirement of these patients.
Conclusion: The number of days of non- adherence to the diet was less than that of the fluid intake recommendations. Also, the degree of non-adherence were more severe for diatary recommendations, compared to fluin intake limitations.
