Protein-energy wasting syndrome in advanced chronic kidney disease: Prevalence and specific clinical characteristics

Introduction: Protein-energy wasting (PEW) is associated with increased mortality and differs depending on the chronic kidney disease (CKD) stage and the dialysis technique. The prevalence in non-dialysis patients is understudied and ranges from 0 to 40.8%. Objective: To evaluate the nutritional sta...

Description
Summary:Introduction: Protein-energy wasting (PEW) is associated with increased mortality and differs depending on the chronic kidney disease (CKD) stage and the dialysis technique. The prevalence in non-dialysis patients is understudied and ranges from 0 to 40.8%. Objective: To evaluate the nutritional status of a group of Spanish advanced CKD patients by PEW criteria and subjective global assessment (SGA). Patients and methods: Cross-sectional study of 186 patients (101 men) with a mean age of 66.1 ± 16 years. The nutritional assessment consisted of: SGA, PEW criteria, 3-day dietary records, anthropometric parameters and bioelectrical impedance vector analysis. Results: The prevalence of PEW was 30.1%, with significant differences between men and women (22.8 vs. 33.8%, p
