The aim of this article was to determine trends in infant mortality and related risk factors in Porto Alegre, Rio Grande do Sul State, Brazil. The study was based on data from a live birth and infant death registry for the years 1996 to 2008. Times trends were analyzed for overall and partial infant mortality rates according to maternal schooling, number of prenatal visits, maternal age, number of live and dead children, sex of the newborn, type of delivery, birth weight, and type of hospital. Poisson regression was used to estimate the influence of socioeconomic status and other risk factors. The infant mortality rate dropped among mothers with less than 11 years of schooling. There were no significant changes among newborns of mothers with 12 or more years of schooling. Maternal socioeconomic status was the factor most closely associated with the reduction in infant mortality. Still, the downward trend failed to achieve its full potential, due to the increase in low birth weight.
本文旨在确定巴西南里奥格兰德州阿雷格里港的婴儿死亡率趋势及相关风险因素。该研究基于1996年至2008年的活产和婴儿死亡登记数据。根据母亲受教育程度、产前检查次数、母亲年龄、存活和死亡子女数量、新生儿性别、分娩类型、出生体重和医院类型，分析了总体和部分婴儿死亡率的时间趋势。采用泊松回归估计社会经济地位和其他风险因素的影响。受教育年限不足11年的母亲所生婴儿的死亡率有所下降。受教育年限为12年及以上的母亲所生新生儿的死亡率没有显著变化。母亲的社会经济地位是与婴儿死亡率下降最密切相关的因素。然而，由于低出生体重儿数量的增加，下降趋势未能充分发挥潜力。
