Introduction: Peritoneal dialysis is a renal replacement therapy that allows the patient to live with a certain degree of autonomy and flexibility. Nutritional diagnosis is crucial, considering the high prevalence of nutritional disorders amongst this population and its correlation with the clinical prognosis. The aim of the current study is to evaluate the nutritional state of patients receiving peritoneal dialysis. Methodology: This is a cross-sectional study realized with 30 patients undergoing peritoneal dialysis. Data collection was undertaken by scheduling appointments for nutritional assessment in which the following data were collected: anthropometric data, body composition, subjective global assessment, assessment of food consumption by means of 24-hour dietary recall and food frequency questionnaire. Biochemical tests and clinical history were obtained from the patients’ records. Results: Most patients were in good nutritional state, euvolemic. A positive statistical association was observed regarding phase angle and lean mass. The biochemical examinations showed that albumin, HDL-c and vitamin D levels were below reference values, whilst phosphorus and parathyroid hormone were above the ideal values. While glucose in the dialysate did not present any statistical association with regard to serum glucose, glycated hemoglobin or triglycerides, it demonstrated statistical association in relation to the preservation of somatic muscle mass. Food consumption assessment showed inadequate protein intake. Conclusion: Patients had good nutritional state and statistical association for a satisfactory prognosis, but nutritional follow-up was important in order to avoid complications.
