This study tested the hypothesis that bioelectrical impedance vectors, group and individual, are valid indicators of total body water (TBW) and hydration status in women experiencing fluid gain and loss during and after pregnancy.We measured TBW, assessed with D 2 O dilution, and resistance (R) and reactance (Xc), determined with 800 μA at 50 kHz and standardized for height (H) and plotted...
Maternal body composition undergoes a deep adaptative change during the course of pregnancy. Fat mass, fat-free mass, and total body water (TBW) increase in different ways and their effects on pregnancy outcome represent a field of major interest in perinatal medicine. The aim of this study was to evaluate the changes in maternal body composition [maternal weight, TBW, intracellular water (ICW) and...
We assessed total body water (TBW) content and cardiac function in 25 normotensive (N) and 22 gestational hypertensive (GH) women matched for age, gestational age, and prepregnancy body mass index (BMI) during the third trimester of gestation. Patients underwent maternal echocardiography, bioelectrical impedance analysis (BIA), and hematocrit (Hct %) evaluation. The TBW:Hct ratio (water balance index,...
