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

本研究回顾了以下几年围产儿死亡率的变化和差异 在技术和医疗快速变革的时期，相似的人口 高危妊娠的管理。 它将探索某些城市的高新生儿死亡率是否 可以用晚期胎儿死亡率向新生儿死亡率的转移来解释 期间，并将比较围产期体验的差异 种族和城市规模。该方法将是对数据集的二次分析 由国家卫生统计中心提供，基于100% 报告围产儿死亡情况。各时期胎儿死亡率回顾 20-27和28+妊娠期和0-7和8-28期间新生儿死亡 天数将被用来检查城市之间潜在的报告差异 以及将新生儿死亡转移到后一时期。 这些数据尚未公开分析。分析 应提供关于怀孕真实结果的新基线信息 在生物相似的种群中。

This study reviews changes and differences in perinatal mortality for similar populations over a period of rapid change in technology and medical management of high risk pregnancies. It will explore 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 will compare differences in perinatal experience according to race and city size. The approach will be a secondary analysis of data sets provided by the National Center for Health Statistics based on 100 percent reporting of perinatal deaths. Review of fetal death rates for the periods 20-27 and 28+ gestation and of neonatal deaths for the periods 0-7 and 8-28 days will be 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 should provide new baseline information on the true outcome of pregnancies in biologically similar populations.
