Is there a correlation between subjective global assessment and food intake, anthropometric measurement and biochemical parameters in nutritional assessment of haemodialysis patients?.
Pak J Med Sci Jan ;25(2):201-6.

Objective: Subjective Global Assessment (SGA), a semi-quantitative method of evaluation for nutritional status, has a widespread use among haemodialysis patients both in research studies and in clinical practice. This study was performed to analyze possible correlations between SGA and food intake, anthropometric measurements, bioelectrical impedance (BIA) and biochemical parameters in haemodialysis patients. Methodology: The cross-sectional study was conducted on 150 Haemodialysis (HD) patients. HD patients were assessed by SGA, 3-day food intake, anthropometry, and some biochemical parameters. Results: According to the SGA 47.3% of patients were well nourished (SGA-A), 37.4% were moderately malnourished (SGA-B) and 15.3% were severely malnourished (SGA-C). While there was a negative correlation between energy, fat intake and SGA score (p=0.025 and p=0.003, respectively), a correlation between carbohydrate, protein intake and SGA score was not found. There were a negative correlation between SGA and serum total protein (p=0.035), albumin (p=0.024) and haemoglobin levels (p=0.001) and a positive correlation between C Reactive Protein (CRP) (p=0.001). Conclusions: Subjective Global Assessment (SGA) was correlated with energy and fat intake and some biochemical parameters, but not with anthropometric measurements. Therefore, we conclude that further studies in which SGA with objective methods are used may be of value in determining nutritional status of haemodialysis patients.
