title: Prevalence of congenital anomalies in neonates and associated risk factors in a tertiary care hospital in eastern India.
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.
  
  
  OBJECTIVE
  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 cross-sectional descriptive study was carried out in the neonatal care unit of R. G. Kar Medical College and Hospital during the period of September 2011 to August 2012. 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, 12,896 babies were born, of which 286 had congenital malformations, making the prevalence 2.22%. Most of the women (55.7%) 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.
  
  
  CONCLUSIONS
  Public awareness about preventable risk factors is to be created and early prenatal diagnosis and management of common anomalies is strongly recommended.
