GUERRA, Fernando Antônio Ramos et al. Birth defects in Rio de Janeiro, Brazil: an evaluation through birth certificates (2000-2004). Cad. Saúde Pública [online]. 2008, vol.24, n.1, pp. 140-149. ISSN 0102-311X. http://dx.doi.org/10.1590/S0102-311X2008000100014.
To evaluate the occurrence of birth defects in the city of Rio de Janeiro, Brazil, using the Live Birth Information System (SINASC), we performed a cross-sectional study on all live newborns with birth defects from January 1, 2000, to December 31, 2004. The variables referred to birth defects (presence and system affected), type of health service, mothers, gestations, live births, and deliveries. Prevalence of birth defects was 83/10,000 live births. The most frequent birth defects involved the musculoskeletal system, central nervous system, cleft lip and palate, and chromosomal anomalies. The majority of cases were born in public (municipal) and private maternity hospitals, with the highest prevalence in the Fernandes Figueira Insitute, Oswaldo Cruz Foundation. Older women and those with less schooling had more live born infants with birth defects. The proportion of reports with missing information was high, reaching 21% in some institutions. Wider dissemination of SINASC data on birth defects should be encouraged. Reliability studies are recommended for better use of these reports.
