Assessment of risk for small for gestational age at midgestation to define subsequent care

Background Previous studies have demonstrated that a competing risks model for the prediction of small-for-gestational-age neonates has a superior performance than traditional risk scoring methods. The Fetal Medicine Foundation fetal and neonatal population weight charts are derived from sonographic estimated fetal weight rather than birthweight because a large proportion of neonates born before term result from pathologic pregnancy. The individualized risk assessment for small for gestational age at midgestation could be the basis of an antenatal plan that aims to improve the management of preterm pregnancies with small for gestational age with minimum resources. Objective This study aimed to stratify subsequent assessments after 24 weeks of gestation based on the estimated risk of delivery of small-for-gestational-age neonates at
