Assessment of nutritional status in hemodialysis patients

Objective To evaluate the nutritional markers in hemodialysis patients.Methods We examined SGA,dietary diaries,direct anthropometry,biochemical indices in 142 maintenance hemodialysis(MHD)patients.Results Patients were classified into three groups,normal nutrition,mild-to-moderate malnutrition,severe malnutrition based on SGA.The dietary protein intake(DPI),dietary energy intake(DEI),serum albumin(Alb),were significantly different among three groups(P0.001~0.05).The abnormal rates of measures in normal nutrition group were 49.0% for DPI and 46.0% for DEI.In severe malnutrition group,the abnormal rates of all data were above 80%.Serum pre-albumin(PA)was correlated with Alb(P0.001),but not with DPI or DEI.Conclusions SGA is a clinically simple method to measure nutritional status in maintenance hemodialysis patients.Other measurements reflecting different aspects of nutritional status are needed,such as DPI,DEI,Alb,PA.
