Prevalence of Protein-energy Wasting and Obesity Among Danish Dialysis Patients

Classification of undernutrition Undernutrition was assessed 3 different methods: 1) WHO cut-off of BMI \< 18,5kg/m2, 2) the criteria for protein-energy wasting (PEW) defined by the International Society of Renal Nutrition and Metabolism (ISRNM) and 3) our own criteria for PEW based on fat mass index (FMI) and a lean body mass index (LBMI). According to ISRNM, PEW is present if at least one abnormal measure is recorded is in at least three of the four categories. We measured the four markers: albumin, BMI, corrected mid-arm muscle area (cMAMA) and normalized protein catabolic rate (nPCR) (a measure of daily protein intake (DPI)). Classification of under nutrition BMI \< 18,5kg/m2 FMI\<10th percentile and LBMI \<10th percentile PEW 3 of 4: * Serum albumin \< 38g/L * BMI \< 23 * cMAMA reduction \>10% in relation to 50th percentile of reference population * Unintentional low DPI \< 0,8g/kg/d
