[Non-invasive methods for evaluation of body composition during weight reduction]

As a result of positive energetic balance of organism, there is a cumulation of an excessive energy in the adipose tissue. Adipose tissue repletion represents the main characteristic of obesity. The objective of our work was to perform the comparative study for the evaluation of selected noninvasive methods used for the determination of body composition. We analysed the results of 4 methods of the body composition measurement: bioelectrical impedance (BIA), physical anthropometry (ANTHR), Deurenberg's calculation (FORM) and dual energy X-ray absorptiometry (DEN). The most statistically significant correlation was proved between the results of BIA and results of DEN method (r = 0.9145), and results of BIA and FORM method (r = 0.9014).
