NAVARRETE HERNANDEZ, Eduardo et al. Prevalence of congenital malformations recorded on the birth certificate and fetal death, Mexico, 2009 to 2010. Bol. Med. Hosp. Infant. Mex. [online]. 2013, vol.70, n.6, pp.499-505. ISSN 1665-1146.

Background. Congenital malformations are a main cause of infant death, chronic illness and disability in several countries. The expected frequency is ~2-3% in live newborns and ~15-20% in stillbirths. In 2010 in Mexico, infant mortality ranked in second place with a rate of 336.3/100,000 births. In order to estimate prevalence and main causes of congenital malformations in live births and stillbirths, national base registries of newborns and stillbirths were evaluated for 2009-2010. Methods. Databases of neonatal live births and fetal deaths were combined. Results. From a total population of 4,123,531 certificates, 99.3% were live born and there were 0.7% fetal deaths. Congenital malformations were registered in 30,491 cases, 91.7% of live newborns and 8.3% of fetal deaths with a prevalence rate of congenital malformations of 73.9/10,000. Conclusions. The reported prevalence was lower than expected. It is necessary to enforce registry systems through system validation and training of personnel.
