OBJECTIVE: Identify trends for different types of birth defects and their impact on infant (IMR) and neonatal (NMR) mortality rates in Costa Rica from 1981 to 2010.
METHODS: Infant, neonatal, and postneonatal mortality trends were analyzed, using data from the Central American Population Center, which uses the International Classification of Diseases, versions 9 and 10, to classify causes of death. For each group of birth defects, a Poisson log-linear regression model was constructed. IMR and NMR, relative risk, and 95% confidence intervals (95%CI) were calculated for the three decades (1981-1990, 1991-2000, and 2001-2010). Estimates were compared using Wald chi square.
RESULTS: Comparison of the 1980s and the 2000s found a significant decrease in NMR and IMR from birth defects in these decades, from 2.37 (95%CI: 2.26-2.48) to 2.13 (2.03-2.23) and from 4.13 (3.99-4.27) to 3.18 (3.05-3.31), respectively. Reduction in IMR was significant for birth defect groups for nervous, digestive, and circulatory systems. There was also a significant drop in NMR for nervous and digestive system groups. All other groups experienced a significant increase or no change.
CONCLUSIONS: IMR and NMR from birth defects have decreased, although these rates have increased proportionately due to a greater decline in other causes. This reduction is much smaller for neonatal mortality. Primary prevention and neonatal care of birth defects should be strengthened.
