This study sought to describe the changes in mortality among infants under one year of age in different areas of the city of Salvador, Bahia, during the period 1980-1988. This was done using estimates of variation in two indicators: proportional infant mortality and the coefficient of infant mortality. Values for the first indicator were separated into low, intermediate, high, and very high quartiles for 1980 and then calculated again using 1988 data. The second indicator was derived from the estimated number of live births using the rate of 33.4/1,000 inhabitants for 1980 and 31.4/1,000 for the years thereafter. The results showed that infant mortality in that age group had declined over the period, but that at the end of the period inequalities persisted in the distribution of infant deaths, which confirmed that conditions remained adverse for certain segments of the population.
本研究旨在描述1980年至1988年期间,巴伊亚州萨尔瓦多市不同区域一岁以下婴儿的死亡率变化情况。这是通过对两个指标的变化估计来完成的:婴儿死亡率比例和婴儿死亡系数。第一个指标的值在1980年被分为低、中、高和非常高四分位数,然后在1988年再次计算。第二个指标是根据估计的活产数得出的,1980年采用每1000名居民33.4的比率,此后各年采用每1000名居民31.4的比率。结果显示,该年龄组的婴儿死亡率在此期间有所下降,但在该时期末,婴儿死亡分布的不平等现象仍然存在,这证实了某些人群的状况仍然不利。
