[The relationship between maternal body weight index and fetal weight and delivery mode]
1401 Hospital of PLA, Qingdao.
Objective:
To study the relationship between maternal body weight index (BWI) and fetal weight and delivery mode.
Method:
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).
Conclusion:
Maternal BWI is a valuable index for estimating fetal weight.

Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
