Background: Our objective was to compare short term outcomes between neonates who delivered as a result of IUGR and preeclampsia PTL with those delivered due to other causes within prespecified gestational age subgroups. Materials & Methods: This was a cross-sectional study being performed at Hafez and Zeinabieh Hospitals, both tertiary healthcare centers affiliated with Shiraz University of Medical Sciences, during a 24-months period from March 2014 to February 2016. Medical records of the mothers who delivered preterm birth during the study period in these two hospitals were reviewed. Results: After considering exclusions criteria, and uncomplete documents, a total of 1698 preterm neonates were included during the study period. Among them there were 896 (52.8%)males, 798 (47%) females, and 4 (0.2%) genital ambiguity. The mean age of the mothers were found to be 29.6 (range 14-53) years. Among the participants there were 663 (37.3%) primigravida. Singleton pregnancy was found in 1219 (72%) mothers and 479 (28%) mothers had twin or more pregnancies. The most preterm birth was occurred between 34-37 weeks of gestation. Conclusion: Our data demonstrate that short-term neonatal outcomes differ by the etiology of PTB. Recognizing differences in neonatal outcomes at varying gestational ages as a function of the etiology of PTB can help facilitate proper patient counseling and allocation of resources.
