title: [The relationship between maternal body weight index and fetal weight and delivery mode].
abstract: OBJECTIVE
  To study the relationship between maternal body weight index (BWI) and fetal weight and delivery mode.
  
  
  METHODS
  Eight hundred and seventy two normal pregnant women were studied from Jan. 1993 to Dec. 1993 BWI [BWI = weight(kg)/Height(m2)] was calculated in each antenatal visit. The comparing analysis of BWI was done. The study group included 126 mothers with fetal weight > or = 4 000g, the control group consisted of 126 mothers with normal fetal weight.
  
  
  RESULTS
  In term pregnancy, the BWI of study groups was significantly higher than that of control group. (P < 0.01). When BWI > or = 27, the rates of macrosomia and cesarean section were markedly increased (P < 0.01).
  
  
  CONCLUSIONS
  Maternal BWI is a valuable index for estimating fetal weight.
