Avaliação dietética e laboratorial em pacientes renais crônicos do município de Itaqui

Abstract

To compare dietary intake, hematological and biochemical parameters in hemodialysis patients with and without adherence to nutritional guidelines appropriate to this pathology. Methods: Sixteen patients undergoing hemodialysis were included in this cross sectional study. Patients were divided into two groups, according to adherence (Group 1) or not (Group 2) of the guidelines proposed by the nutritionist. The body mass index was used for classification of nutritional status and diet was assessed using three 24- hour dietary recalls. Biochemical tests were obtained from the medical records of each patient. Results: Mean age was 62±10 and 48±10years in groups 1 and 2, respectively. Patients had a median body mass index within recommended. The nutrient intake did not differ between groups, with the exception of liquid and total kcal (38% and 49% higher than that observed in group 1, respectively). The adequacy of protein intake according to the Dietary Reference Intakes was 100% for both groups, however, when assessed by the recommendation for g/kg/ day, group 1 have mean intake below recommendation (0.74±0.25 g /Kcal /day). Conclusion: The present study show inadequacies in nutrients intake in both groups. In addition, energy and protein recommendations vary according to the guide used, and must not be generalized, since the data available show that this consumption can differ depending on the condition of each patient.
