Objective: We aimed to compare the perinatal outcomes in late preterm spontaneous and indicated birth neonates. Methods: We studied 289 late preterm births, classified as either aspontaneous late preterm birth (sLPTB) group (preterm labor with intact membranes and preterm premature rupture of membranes) or an indicated late preterm birth (iLPTB) group (hypertensive disorder in pregnancy, placental causes, and maternal diseases), according to the delivery indication. We then compared the

Results: A total of 198 neonates were in the sLPTB group and 91 were in the iLPTB group. In spite of greater gestational age at the time of delivery in the iLPTB group, the mean birth weight was lower than that in the sLPTB group. Additionally, the iLPTB group showed lower Apgar scores, and higher rates of NICU or SCN admission, respiratory support, and hypoglycemia, but there was no difference in the rate of composite morbidity between the two groups. Conclusion: iLPTB neonates had lower birth weights despite greater gestational age than those in the sLPTB group, but there was no difference in the rate of composite morbidity between the two groups.
