[Nutritional rehabilitation and evaluation of the nutritional state. Validity of anthropometric measures for following, in hospitalized patients, the course of nutritional status and of body compartments during nutritional recovery].

A population suffering from a serious form of malnutrition was examined. The effectiveness of nutritional rehabilitation is demonstrated by the statistically significant changes observed in clinical and laboratory indicators. Several anthropometric measurements related to nutritional status are also compared with total body potassium (TBK) in patients with a positive nitrogen balance during the process of nutritional rehabilitation. It is concluded that weight (W), arm circumference (AC), middle arm muscle circumference (MAMC) and skinfold thickness (ST) measures are useful, and sufficiently accurate and precise to follow the evolution of nutritional status and body compartments.
