A large head circumference is more strongly associated with unplanned cesarean or instrumental delivery and neonatal complications than high birthweight

摘要

OBJECTIVE: Fetal size impacts on perinatal outcomes. We queried whether the fetal head, as the fetal part interfacing with the birth canal, might impact on obstetric outcomes more than birthweight (BW). We examined associations between neonatal head circumference (HC) and delivery mode and risk of perinatal complications as compared to high BW.
