Objective To compare prenatal risk factors and neonatal morbidity between small for gestational age (SGA) infants and appropriate for gestational age (AGA) infants in late-preterm birth. Methods Neonatal morbidity and prenatal of 121 SGA infants delivered between 34~36+6 weeks of gestational age were retrospective analyzed.The control group consisted of 754 infants with spontaneous preterm delivery at the same gestation, in which the infant was AGA. Results In SGA group length of stay of NICU was longer than AGA.The frequency of hypertensive disorder complicating pregnancy, oligohydramnios, abnormality of umbilial cord, multiple pregnancy, fetal distress were higher than those in AGA group(P<0.05).SGA infants were found to be at higher risk of hypoglycemia, feeding intolerance, polycythemia, septicemia (P<0.05). Conclusions Late-preterm SGA infants present a significantly higher risk of neonatal complications when compare to late-preterm AGA infants.
