Abstract
Objectives: To evaluate the nutritional status of hemodialysis (HD) patients. Methods: A cross-sectional study was performed in all patients on HD at a single center. Results: We studied 72 patients, male (57%) and 45.8% between 45 and 64 years old. The most frequent etiology was systemic arterial hypertension (50.0%) and diabetes (20.8%). KT/V > 1.2 was found in 88.8% of the patients, and phosphorus level > 5.5 mg/dL in 25%. The malnourished patients classified by body mass index (BMI) < 25 kg/m2 (66.67%), arm muscle circumference (WBC) index (84.72%) and albumin (≤ 4.0 g/dL) (28,8%), and 22,22% use a specific oral nutritional supplement for hypercaloric hyperproteic dialytic patients, provided by the hemodialysis service. The mean interdialytic weight gain (GPIDm) was < 2.5kg in 58.3% and the relative interdialytic weight gain (GPIDr) was < 4.5% in 75.0% of the patients. There was a significant association between GPIDm and CMB, patients with lower GPIDm (≤ 2.5 kg) tended to have more mild or moderate malnutrition (p = 0.003). No differences were observed by time in hemodialysis in relation to age, interdialytic weight gain, laboratory and anthropometric measurements. Conclusion: The nutritional assessment by BMI was in agreement with the Brazilian literature. By CMB, most were classified as malnourished, which differs from albumin, in that only ∼ 30% were malnourished. The results show the importance of supplementation for this population. We have seen that > 75% of the patients are within the ideal GPIDr (< 4.5% of the dry weight). The dialysis time did not affect the nutritional evaluation parameters.
