A new nutritional assessment in patients with oral and maxillofacial malignancies.
Combined subjective and objective nutritional assessment was performed on admission in 127 patients with oral and maxillofacial malignancies. On the basis of the nutritional assessment result, three typical nutritional parameters-body weight (BW) (X1), mid-upper-arm circumference (MAC) (X2), and hand grip strength (HGS) (X3) were used to establish a new nutritional assessment method that was developed by a computer-based discriminant analysis. The established model was as follows: Y1 = -126 + 1.09X1 + 1.34X2 + 0.23X3; Y2 = -95.63 + 0.96X1 + 1.17X2 + 0.19X3. In the model Y1 was regarded as good nutrition and Y2 as malnutrition. The larger value of Y stood for the patient's nutritional status (i.e. Y1 > Y2, well nourished; Y1 < Y2 malnourished). The new nutritional assessment correlates well with the combined subjective and objective nutritional assessment with a total agreement rate of 88.2%. With its simplicity and accuracy, the new nutritional assessment deserves a wide application in clinical situation.
