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.
