Abstract:
Objective To explore the feasibility of bioelectrical impedance analysis in assessing resting energy metabolism(REM)and the association of REM with anthropometry in hemodialysis patients.Methods Adult hemodialysis patients from 11 hemodialysis facilities in Guizhou Province were enrolled in this study.Bioelectrical impedance analysis was used to measure the rest metabolic rate(RMR)and body composition of 765 patients undergoing regular dialysis.A standard method was used to measure their height,weight,upper arm circumference,triceps skinfold thickness,left calf circumference and grip strength.The upper arm muscle circumference was also calculated.The level of RMR and body composition in hemodialysis patients were compared by gender grouping.The patients were then divided into four groups according to the RMR quartile.Spearman correlation analysis and multiple linear regression analysis were derived to analyze the relationship between RMR and anthropometry.Results The level of RMR in male patients was significantly higher than that in female patients[1591(1444,1764)Rcal/d and 1226(1104,1354)Rcal/d,P ＜ 0.001].Compared with the first quartile of RMR group,upper arm circumference,upper arm muscle circumference,left calf circumference and grip strength in the fourth quartile group were increased significantly(all P ＜ 0.05).Multiple linear regression analysis showed that height(β=0.572),left calf circumference(β=0.273),upper ann muscle circumference(β=0.092)and suffering from protein energy wasting(PEW,β=-0.184)were independent influential factors of RMR(all P ＜ 0.05).Conclusions RMR levels in patients with maintenance hemodialysis are associated with left calf circumference and upper ann muscle circumference,which may become a new index to evaluate energy consumption and malnutrition in MHD patients.
