CHANGES IN PERINATAL AND INFANT MORTALITY BY RACE IN SELECTED U.S. CITIES

这项研究描述了围产儿死亡率和年龄的差异 从1972年到1981年，59个大城市的死亡人数迅速变化 在高危妊娠的技术和医疗管理方面。 它探索了高新生儿死亡率是否在某些情况下 城市可以用晚期胎儿死亡率的变化来解释 并比较围产期的差异 根据种族和城市规模的死亡年龄来体验。一个 对国家数据中心提供的数据集进行二次分析 健康统计是基于100%的报告完成的 围产期死亡。24周胎儿死亡率回顾 胎龄和新生儿死亡率，1-7和 8-27天用于检查潜在的报告差异 城市之间的差异和新生儿死亡向后者转移 句号。这些数据尚未公开分析。 该分析为比较提供了改进的标准。 不同地理位置的围产儿死亡率。

This study describes differences in perinatal mortality and age at death in 59 large cities from 1972 through 1981, of rapid change in technology and medical management of high risk pregnancies. It explores whether high rates of neonatal mortality in certain cities can be explained by shifts in mortality from the late fetal to the neonatal period and compares differences in perinatal experience according to age at death by race and city size. A secondary analysis of data sets provided by the National Center for Health Statistics was done based on 100 percent reporting of perinatal deaths. Review of fetal death rates from 24 weeks gestational age and of neonatal deaths for the periods, 1-7, and 8-27 days is being used to examine potential reporting differences among cities and shifting of neonatal deaths into the latter period. These data have not been available publicly for analysis. The analysis provides in improved standard for comparison of perinatal mortality in differing geographic sites.
