Gross Congenital Anomalies at Birth in Northeast India- A Retrospective Observational Study

Introduction: Congenital Anomalies (CA) are a significant cause of neonatal mortality both in developed and developing nations. Congenital abnormalities can have different patterns, prevalence rates, and risk factors across time and across different geographic regions. Aim: To find out the incidence of CA occurring among institutional live births and to study the associated maternal and perinatal risk factors in Northeast region of India. Materials and Methods: This retrospective observational study was carried out in the Neonatal Intensive Care Unit (NICU) at a Tertiary Care Hospital, Guwahati, Assam, India. The duration of the study was from January 2019 to December 2019. All newborns with CA during this period were included. Maternal and labour ward records were obtained. Data of maternal and antenatal factors such as age, parity, history of consanguinity, family history of congenital abnormality and mode of delivery were collected. The data were analysed using Microsoft Excel and Statistical Package for Social Sciences (SPSS) version 26.0 (IBM SPSS Statistics for Windows, Armonk, NY, USA). Proportion was calculated and the association was tested with Chi-square test and Fisher’s-exact test. p
