To study the relationship between maternal body weight index (BWI) and fetal weight and delivery mode.
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.
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).
Maternal BWI is a valuable index for estimating fetal weight.
研究孕妇体重指数（BWI）与胎儿体重及分娩方式之间的关系。
对1993年1月至1993年12月期间的872名正常孕妇进行研究。每次产前检查时计算BWI[BWI =体重（千克）/身高（平方米）]。对BWI进行比较分析。研究组包括126名胎儿体重≥4000克的母亲，对照组由126名胎儿体重正常的母亲组成。
足月妊娠时，研究组的BWI显著高于对照组（P<0.01）。当BWI≥27时，巨大儿发生率和剖宫产率显著增加（P<0.01）。
孕妇BWI是估计胎儿体重的一个有价值的指标。
