SGA Scores Have Poor Correlation With Serum Albumin in Obese Hemodialysis Patients: A Secondary Analysis

The objective of this study was to determine the relationship between serum albumin and the Subjective Global Assessment (SGA) in a sample of obese hemodialysis (HD) patients.Design and Method: Study subjects (N = 253) included patients who were categorized into well-nourished (68%, SGA score 6-7) and malnourished (score 1-5) groups, and, on the basis of the body mass index (BMI), into obese (BMI > 30 kg/m2; 35%) and nonobese (BMI < 30 kg/m2). The mean baseline data (±standard deviation) were as follows: age, 63.5 ± 14.3 years; BMI, 29 ± 8 kg/m2; and serum albumin, 3.8 ± 0.4 mg/dL (bromocresol green). The secondary analysis of data from the SGA Validation Project and Nutrition Algorithm Preliminary Report determined the relationship between the 7-point SGA and serum albumin concentrations in a sample of obese HD patients. Data were analyzed at Case Western Reserve University from a total of 253 HD patients.Main Outcome Measure: The SGA scores in the BMI groups were compared with serum albumin as an objective measure of nutrition and inflammation risk.Results: By using analysis of variance, the obese and nonobese populations showed statistically significant differences in SGA scores (obese: P
