Bioimpedance spectroscopic body analysis during lactation.
Urbánková, Tereza ; Hronek, Miloslav (advisor) ; Kovařík, Miroslav (referee)
The aim of the diploma thesis was to cover the changes in body composition by bioimpedance spectroscopy in Czech breastfeeding women during three periods - 3 weeks postpartum, 3 months and 6 months postpartum. Eight healthy breastfeeding women were involved in the study. At each examination there were measured anthropometric parameters and bioimpedance spectroscopy parameters by the Body Composition Monitor. Breast milk was also extracted during the study. We observed a gradual decrease in body weight of monitored women. The median weight loss between the first and third examination was 2,2 kg, the median weight in 6 months postpartum was 1,3 kg higher than the median of prepregnancy body weight, two of the women had lower weight 6 months postpartum than before the pregnancy, the body weight of other six women was higher in a scale between 0,1 kg to 3,1 kg. There were not proven statistically significant differences in body composition during lactation. A trend of decrease of TBW was observed during all lactation periods. A trend of slight increase of ICW was observed between the 3rd week and 3rd month postpartum, and then the decrease of ICW in the 6th month postpartum. An increase of LTM and BCM was measured between the 3rd week and 3rd month postpartum, those values have shown a decrease again...

Bioimpedance analysis of body fluids during pregnancy.
Najpaverová, Simona ; Hronek, Miloslav (advisor) ; Kovařík, Miroslav (referee)
The aim of this work was to process opportunities of bioelectrical impedance analysis (BIA) for determination body composition of pregnant women. There is quite small findings about this issue, so it was an effort to prove the usefulness of the BIA method during pregnancy and than to clarified the changes of body metabolism in women during pregnancy. The study included 10 pregnant, primipara, women with a physiological pregnancy. The screening was performed by the method of bioimpedance analysis of body composition, which records the amount of water, muscle and fat mass in the body. The measured values recorded an increase in mass of all examined women on average of 13.4 ± 4.1 kg. Our results also recorded progressive increase in the amount of total body water (TBW), extracellular water (ECW) and intracellular water (ICW) especially during the last trimester of pregnancy. The results analysis showed the tightest correlation between the values of Re and ratio of TBW P/h2 (p = 1,23*10-20 ; r = -0,98057) and of Ri and ratio of ICW P/h2 (p = 4,52*10-20 ; r = -0,97859), too. The evaluation of measurements between the first and third trimester has shown statistically significant difference in values Xc/waist. It has been shown that using the BIA method is justified in period of pregnancy and it is...
