Abstract:
Objective: The purpose of this study was to investigate the relationship among the maternal body composition,gestation weight gain and fetal birth weight.Methods: Pregnant women with a singleton gestation and without medical diseases before pregnancy were enrolled.Anthropometry measurements and bioelectrical impedance measurements were performed during 24-25 weeks(the second trimester) and 37-38 weeks(the third trimester).Results: Gestation weight gain was correlated significantly with gains of intracellular fluid,extracellular fluid,total body water,body fat,fat free mass,body cell mass,mother's basal metabolic rate and arm circumference seperately,which were correlated with the fetal birth weight(P0.05).Conclusion: Maternal weight gains during pregnancy were affected by their body composition.Fat free mass is considered an important predictor of fetal birth weight.
