Manotas M, et al. - Data from the Bogotá Birth Defects Surveillance and Follow-up Program was used, which combined data about 167 ECLAMC study (Estudio Colaborativo Latino Americano de Malformaciones Congénitas, in spanish) variables in a case-control design was assessed by the researchers in order to assess risk factors correlated with congenital defects that modify hearing or vision in 402,657 newborns in the city of Bogotá between 2002 and 2016. A total of 968 cases had some congenital defects that altered hearing or vision. A correlation was discovered between the presence of defects and prematurity, as well as between syndromic subjects and progressing maternal age. When comparing cases and controls with the risk of having a birth defect, multiparity, acute respiratory infection, low maternal education level, low paternal education, manual labor in the maternal occupation, a history of congenital anomalies in the family had an odds ratio of 1.47, 2.41, 1.34, 1.42, 1.31, and 1.55, respectively. Hence, in the population of Bogotá, this research enabled the classification of epidemiological data and important risk factors for congenital defects that alter hearing or vision.
