Infant deaths were classified as avoidable, non-avoidable, and resulting from ill-defined conditions, from 1997 to 2006, using the Brazilian List of Avoidable Causes of Mortality. Non-linear regression was used to calculate trends in cause-specific infant mortality rates. There was a significant decline in both avoidable deaths and deaths from ill-defined causes (p < 0.001). Avoidable deaths decreased by 37% overall. Mortality avoidable through adequate intrapartum care and adequate neonatal care decreased by 27.7% and 42.5%, respectively, while mortality avoidable through adequate prenatal care increased by 28.3%. In conclusion, health services contributed to the reduction in infant mortality. The decrease in ill-defined causes of death indicates expanded access to health services. The increase in access to intrapartum and neonatal care contributed to the reduction in infant deaths. The increase in mortality avoidable through adequate prenatal care indicates the need for improvement in prenatal care.
1997年至2006年期间，依据巴西可避免死亡原因清单，婴儿死亡被分为可避免死亡、不可避免死亡以及死因不明导致的死亡。采用非线性回归分析计算特定原因的婴儿死亡率趋势。可避免死亡和死因不明导致的死亡均显著下降（p < 0.001）。总体而言，可避免死亡下降了37%。通过充分的产时护理和充分的新生儿护理可避免的死亡率分别下降了27.7%和42.5%，而通过充分的产前护理可避免的死亡率上升了28.3%。总之，卫生服务有助于降低婴儿死亡率。死因不明导致的死亡减少表明获得卫生服务的机会增加。产时和新生儿护理可及性的提高有助于降低婴儿死亡率。通过充分的产前护理可避免的死亡率上升表明产前护理需要改进。
