Abstract: ObjectiveTo determine the correlation between the risk factors of cerebral palsy and gestational age of live born infants. MethodsThe gestational age, the risk factors of cerebral palsy and clinical features of 478 children with cerebral palsy were analyzed retrospectively. ResultsFetal distress, threatened abortion, non-infectious diseases during pregnancy, hypoxic-ischemic encephalopathy, neonatal convulsion, infection of newborn, intracranial hemorrhage and haemolysis did not correlated with the gestational age of children with cerebral palsy (P>0.05). Brain malformation, maternal infection, aspiration pneumonia, neonatal asphyxia and hyperbilirubinemia negatively correlated with the gestational age (P<0.05). The incidence of spasmo-diplegia was significantly different between preterm and term infant (P<0.05). ConclusionThe morbidity of cerebral palsy associated with the merging development malformation, maternal infection, aspiration pneumonia, neonatal asphyxia or hyperbilirubinemia increased as the gestational age declined. The spasmo-diplegia more happened in the preterm infants than in the term ones.
