Abstract:
Objective:To investigate the application of phase angle by bioelectrical impedance in the assessment of malnutrition and its correlation with nutrtition status as measured by several different screening tools in patients on maintenance hemodialysis (MHD).Methods:This was a cross-sectional study, including 151 patients on MHD. Bioelectrical impedance analysis was used to detect body composition in hemodialysis patients. Nutritional Risk Screening 2002 (NRS 2002) scores, body mass index (BMI) and the Global Leadership Initiative on Malnutrition (GLIM) criteria were used to investigate the prevalence of malnutrition in MHD patients. The correlation between phase angle and nutrition-related indicators such as visceral fat area, body weight, skeletal muscle, and serum albumin in MHD patients was analyzed, and the consistency between phase angle and the three screening tools was examined.Results:In a total of 151 patients on MHD, the malnutrition prevalence as measured by BMI, NRS 2002 score and GLIM criteria was 9.27%, 27.81% and 54.97%, respectively. Phase angle in MHD patients was positively correlated with BMI( P<0.01), negatively correlated with impaired nutrition score of NRS 2002( P<0.01), and also associated with nutrition screening results as measured by GLIM criteria( P<0.001). Further study showed that phase angle was positively correlated with body weight, skeletal muscle and serum albumin( P<0.01), but negatively with visceral fat area and extracellular water/total body water( P<0.01). Conclusions:Malnutrition is highly prevalent in MHD patients. Phase angle showed good consistency with BMI, NRS 2002 and GLIM criteria in terms of malnutrition screening, implying the potential application in the assessment of malnutrition in MHD patients. However, the clinical relevance still needs corroboration with future large-scale researches.
