Nevertheless, 70% of neonatal deaths still have a direct correlation with prematurity. It seems that updated statistics of mortality and morbidity rate of very low birth weight infants (VLBW) are necessary for proper planning. Although the mortality and morbidity rates of premature infants have been studied in many countries, there are few studies in this field in Iran. Therefore, this study was done to determine the mortality rate of neonates weighing less than 1500 grams. Materials & Methods This retrospective cohort study was done in 138 premature infants with intrauterine age more than 24 weeks and birth weigh less than 1500 grams. These infants have been hospitalized in neonatal intensive care unit (NICU) of Sarem women’s Hospital during the years 1388-1395. Findings The mean birth weight of these infants was 1077.00±287.00 g and the mean gestational age was 28.90±3.00 weeks. The survival rate was 78.3% in this group. The highest survival rate was in the group of infants weighing 1500-1000 g and 90% of them were discharged from the hospital. The neonatal mortality rate increased with birth weight loss, so that in infants weighing less than 700 g survival rate was 27.8%. Conclusion The mortality rate of infants increases with birth weight loss. In addition, the gestational age and apgar score of the fifth minute are related to neonatal mortality.
