Anemia, overhydration, and lower muscle strength in hemodialysis patients with protein-energy wasting.

Introduction: The protein-energy wasting (PEW) syndrome is a common complication in hemodialysis (HD) patients associated to morbidity and mortality. Our objective was to assess the prevalence of PEW and its association with erythropoietin resistance index (ERI) score, body composition by impedance, health-related quality of life, and muscle strength.

Methods: In this cross-sectional, observational, multicenter study, we included data from 191 HD patients from three HD clinics located in Mexico City, Mexico.
