Prevalence of Congenital Malformations Observed in Neonates in Shariati Hospital (1381-1383)

Background: Congenital malformations are one of the most important problems in pediatrics. The estimation of the prevalence of malformations and some probable determinants were the purpose of this study. Methods: In this retrospective study, all of the newborns that were born during three years (2002-4) were included. Hospital files of 3840 newborns were studied retrospectively and the data were collected in checklist. Finding: 118 cases had at least a major or minor malformation. Over all the prevalence of malformations was 3.1%. Male newborns showed a higher prevalence of malformations than females but with no statistical significance. The skeletal system had the highest rate of malformations, while the genitourinary system and the head and neck deformities were in the second and third position. There were no significant relations between the prevalence of malformations and the maternal age, the height and weight of the newborns and the season of birth. Conclusion: The prevalence of malformations in this study was similar to previous studies.
