title: Birth weight centiles, risk of intrapartum compromise, and adverse perinatal outcomes in term infants.
abstract: OBJECTIVE
  The objective of this study is to evaluate the association between birth weight centiles and the risk of intrapartum compromise and adverse neonatal outcomes in term pregnancies.
  
  
  METHODS
  Retrospective study of 32 468 term singleton births at a major tertiary maternity hospital in Australia. Data comprised gestation, mode, and indication for delivery and adverse perinatal outcomes. Fetal sex and gestational age-specific birth weight centiles were the main exposure variable.
  
  
  RESULTS
  Neonates <21st birth weight centile had an increased risk of intrapartum compromise, the highest risk was in babies <3rd centile (OR 4.04, 95% CI 3.34-4.89). The risk of adverse perinatal outcomes was increased in neonates <21st and >91st birth weight centiles. The highest risk was in those <3rd centile (OR 2.35, 95% CI 2.00-2.75).
  
  
  CONCLUSIONS
  Fetal size measurements near term may be used as part of screening test for identifying fetuses at an increased risk of intrapartum compromise and adverse perinatal outcomes.
