Charles University Faculty of Pharmacy in Hradec Králové Department of Biological and Medical Sciences Student: Nikola Dubňanská Supervisor of master thesis: PharmDr. Miroslav Kovařík, Ph.D. Title of master thesis: Influence of nutrition on changes in body composition in pregnant and lactating women Background The aim of the work was to evaluate changes in parameters of body composition determined by bioimpedance analysis during pregnancy and lactation. At the same time, we wanted to find out relationship between individual parameters and total energy intake and intake of macronutrients namely carbohydrates, lipids and proteins. Methods Body composition parameters were determined by using instruments that are based on the bioimpedance analysis method. Bioimpedance analysis determines the parameters of a body composition from the resistance that various biological tissues show against a weak electric current passing through the body during the measurement. This method is non- invasive, fast, easy to use and also suitable for evaluating body composition in pregnant and lactating women. NutriDan nutritional software was used to evaluate data on energy intake and individual macronutrients obtained from the weekly questionnaire. Results During pregnancy, body weight increased in women and decreased..
