To identify appropriate fetal growth parameters that can be used in clinical practice for predicting macrosomia.
Clinical data of 108 macrosomia babies and 108 babies with normal birth weight who were delivered in 2007 in Sichuan Provincial Hospital for Women & Children were collected and compared. The parameters for the comparisons included maternal abdominal circumference (MAC), fundal height (FH), and fetal diameters measured by ultrasonic imaging such as biparietal diameter(BPD), head circumference (HC), femur length(FL), and abdominal circumference(AC).
Maternal fundal height, fetal biparietal diameter, and biparietal diameter plus femur length produced greater than 0.64 of receiver operator characteristic (ROC) curve area for predicting macrosomia (P < 0.05), with a diagnostic index of 143. 5%, 138. 7% and 149.4%, respectively. Other parameters produced less than 0.63 ROC area for predicting macrosomia, with no statistical significance.
Maternal FH, BPD and BPD plus FL are relatively sensitive parameters for predicting macrosomia.
确定可在临床实践中用于预测巨大儿的合适胎儿生长参数。
收集并比较2007年在四川省妇幼保健院分娩的108例巨大儿和108例出生体重正常婴儿的临床资料。比较的参数包括孕妇腹围（MAC）、宫高（FH）以及通过超声成像测量的胎儿径线，如双顶径（BPD）、头围（HC）、股骨长（FL）和腹围（AC）。
孕妇宫高、胎儿双顶径以及双顶径加股骨长预测巨大儿的受试者操作特征（ROC）曲线面积大于0.64（P<0.05），诊断指数分别为143.5%、138.7%和149.4%。其他参数预测巨大儿的ROC面积小于0.63，无统计学意义。
孕妇宫高、双顶径以及双顶径加股骨长是预测巨大儿相对敏感的参数。
