Abstract

Malnutrition is a major negative prognostic factor in dialysis. In recent years, a subjective global assessment ( SGA ) has increasingly been used to determine the nutritional status of dialysis patients and is recognized as a convenient and reliable method. In this study, we assessed the correlation between SGA scores and objective nutritional parameters in ethnic Chinese ( i.e., Taiwanese ) chronic peritoneal dialysis ( CPD ) patients. The study included 92 patients ( 36 males and 56 females ) treated by CPD. The SGA was performed by a renal dietitian using a 7-point scale, and the nutritional status was determined by measuring the biochemical parameters such as serum albumin, anthropometrics such as the triceps skin-fold ( TSF ) and mid-arm muscle circumference ( MAMC ) , and muscle strength by the hand grip strength ( HGS ). The SGA was positively correlated to serum albumm ' r = 0 538, p < 0.0001 ; , HGS ' r = 0.411, p < 0.0001 ) , and pinch strength ( r = 0.409, p < 0.0001 ) Anthropometric parameters such as the body mass index ( BMI ) , TSF, and MAMC, and the HGS, pinch strength, and serum albumin were significantly higher in well-nourished i SGA 6 ~ 7 scale i dialysis patients than malnourished ( SGA 2~5 scale ) CPD patients (p < 0.05 ) . The SGA is a good clinical method for assessing the nutritional status of CPD patients, so it can be used for the regular assessment of the nutritional status of CPD patients.
