Résumé
Objective: To analyze the clinical characteristics of non-diabetic fetal macrosomia and their mothers.Methods: A retrospective case control study design was used to analyze 149 cases of non-diabetic fetal macrosomia and their mothers with the normal oral glucose tolerance test(OGTT) by comparison with 166 randomly included newborns of normal birth weight.Results: More cases of non-diabetic fetal macrosomia were found in the male neonates.The body weight,height,FL and BPD averaged significantly higher in the macrosomia group than in the control,and so did the body weight,height,uterus height,abdominal circumference and gestational age of the mothers.The rates of cesarean section and other obstetric complications were also higher in the macrosomia group.Conclusion: Different from the diabetic macrosomic fetus,the non-diabetic macrosomic fetus is a normal one,the incidence of which is associated with mothers'excessiver pregnancy nutrition as well as with genetic factors.
Résumé
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.
