Subjective Global Assessment of Nutritional Status of Patients with Chronic Renal Insufficiency and End Stage Renal Disease on Dialysis

摘要

Objective : (1)To assess the nutritional status of chronic renal insufficiency (CRI ) and dialysis patients using the subjective global assessment (SGA) method. (2) To validate SGA in assessing the nutritional status of this group of patients. Participants: The nutritional status of 81 patients was evaluated using dietary recall, anthropometry, biochemical parameters and SGA. There were 51 males and 30 females. Their mean μ SD age was 53.8 μ 14.3 years. There were 27 patients with (CRI) on conservative management, 38 patients with end stage renal disease (ESRD) on maintenance hemodialysis (HD) and 16 patients with ESRD on continuous ambulatory peritoneal dialysis (CAPD). Methods: SGA was done using seven variables derived from medical history and physical examination. Each variable was scored from 1-7 depending on the severity. The SGA scores were correlated with the standard methods. Results: Thirteen (48%) patients with CRI, 22 (58%) patients on HD and 8 (50%) patients on CAPD were malnourished. It was seen that the dietary protein & calorie intake and serum albumin level did not correlate well with the SGA scores. The anthropometric measures correlated with the SGA scores (Skinfolds and SGA r = 0.2, MAC and SGA r = 0.5 and MAMC and SGA r = 0.5). Conclusion : Malnutrition is an important complication in CRI patients and ESRD patients on dialysis. SGA is a reliable method of assessing nutritional status. Most important is the fact that it can detect the changing trend of nutritional status, which may be missed by one-time anthropometry and biochemical methods.
