Abstract

Objective: To compare the Subjective Global Assessment (SGA) and a range of SGA-based assessment tools with body cell mass in Stage IV and V pre-dialysis chronic kidney disease (CKD) patients. Study design: Cross-sectional, observational. Setting: Public tertiary hospital pre-dialysis outpatient clinic----- Patients: A total of 56 consecutive consenting patients with CKD (61% were male; age [mean ± standard deviation] 70.2 ± 11.6 years; glomerular filtration rate 22.2 ± 6.8 mL/min).----- Main Outcome measure: Nutrition status. Results: In this population the prevalence of malnutrition was 19.6% (n=11, SGA B; no C ratings). Malnutrition was associated with lower body cell mass (mean BCM, 26.3 vs. 33.4 kg p=0.007, measured by total body potassium, TBK), body weight (64.8 vs. 76.1 kg p=0.042), BMI (23.7 vs. 27.6 kg/m2 p=0.015) and greater weight loss over previous 6 months (-6.2 vs. -0.1 kg p=0.004). Body cell mass had a weak relationship with 7-point SGA (p=0.267), malnutrition inflammation score (MIS r=-0.27 p=0.063) and patientgenerated SGA (PG-SGA r=-0.27 p=0.060). There was no association for either measure of nutrition status (SGA or BCM) with albumin, glomerular filtration rate or C-reactive protein.----- Conclusion: SGA in its original form most accurately delineated malnutrition by depleted BCM and is the most appropriate tool for cross-sectional assessment of nutrition status in predialysis CKD patients.

14 citations in Web of Science®

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
