A study on Prevalence of Congenital Anomalies in Neonates in a Tertiary Care Hospital.

ABSTRACT

Background: Congenital anomalies are a major cause of stillbirths and neonatal mortality. The pattern and prevalence of congenital anomalies may vary over time or with geographical location. The aim of this study is to determine the proportion and types of congenital anomalies in live newborns and to study maternal and perinatal risk factors. Methods: This prospective study was conducted over a 1 year period (March 2014 to February 2015) in the department of Pediatrics and Obstetrics/Gynaecology at Patliputra Medical College, Dhanbad, Jharkhand during the period of May 2014 to April 2015. All the live born babies born in this hospital during this period were included. The newborns were examined for the presence of congenital anomalies and mothers were interviewed for socio-demographic variables. Results: During the study period, 8546 babies were born, of which 246 had congenital malformations, making the prevalence 2.19%. Most of the women (57.8%) belonged to the age group between 21 and 30 years. Congenital anomalies were seen more commonly (3.3%) in the multiparas in comparison with primiparas (1.8%). The predominant system involved was Musculo-skeletal system (33.2%) followed by gastro-intestinal (GI) system (15%). Talipes (17.1%) was the most common one in musculoskeletal group and likewise cleft lip and cleft palate in GI system. Congenital anomalies were more likely to be associated with low birth weight, prematurity, multiparity, consanguinity and cesarean delivery. Conclusion: Public awareness about preventable risk factors is to be created and early prenatal diagnosis and management of common anomalies is strongly recommended.
