PharmDr. Miloslav Hronek, Ph.D. HRADEC KRÁLOVÉ, 2022/2023 ABSTRACT The aim of this work was to evaluate the prediction of body composition by the method of dual bioimpedance analysis in relation to the prediction of body composition by the method of spectroscopic bioimpedance analysis. Five pregnant women (first-time mothers) with a physiologically ongoing pregnancy were included in the study. Each of them participated in three examinations, specifically in the period between 17.-27. week of pregnancy, 28.-35. week of pregnancy and the 36th-38th week of pregnancy. A Tanita RD-953 personal digital scale (Tanita Corporation, Tokyo, Japan) representing dual bioimpedance analysis and a BCM - Body Composition Monitor (Fresenius Medical Care, Bad Homburg, Germany) representing spectroscopic bioimpedance analysis were used for measurements. The measurement results were compared by statistical analysis. No significant differences were found between the BIA and BIS measurements by the Wilcoxon test. In contrast, the Bland-Altman test found statistically significant differences in the measurement of body fat in the first and second follow-up periods, as well as in the..
