Abstract: The review introduces the establishment of different fetal growth curves commonly used in the world and the applicable population，and compares their clinical value in screening for small-for-gestational-age fetuses as well as in predicting adverse perinatal outcomes. It is recommended to build suitable fetal growth curve to improve the screening sensitivity for small -for-gestation-age fetuses，help predict adverse perinatal outcomes, and provide guidance for the monitoring and management of pregnancy，which is of great significance in reducing perinatal death and the related complications.

Key words: fetal growth restriction, fetal growth curve

摘要： 文章系统介绍并分析比较了国际上常见各类胎儿生长曲线的建立方法、适用人群及用于临床筛查小于胎龄儿及预测不良围产儿结局的价值。提出选择合适的胎儿生长曲线，对提高小于胎龄儿产前筛查的敏感度、预测严重不良围产儿结局，进一步指导孕期监护和管理，减少围产儿死亡和相关并发症的发生具有重要意义。
