我们试图衡量妊娠结局的总体差异，结合来自组成美国人口的许多种族和民族的数据，以提高对差异如何随时间变化的理解。我们使用1989-1990年和2005-2006年美国生命统计局的出生队列关联婴儿死亡数据文件，检查总体婴儿死亡率（IMR）、早产率和胎龄特异性IMR的种族和民族差异的多组指数。我们计算了选定的绝对和相对多组差异指标，平均加权亚组和人口规模。总体婴儿死亡率在绝对尺度上下降，但在人口加权相对尺度上增加。早产率的差异在绝对和相对尺度上都有所下降，在同等加权和人口加权指数上也有所下降。早产儿IMR的差异在绝对和相对尺度上都有所增加。婴儿死亡率是一般健康和妇幼健康的一个共同指标。尽管早产率的差异显著减少，但在过去20年中，总体和早产婴儿死亡率的相对差异显著增加。
We sought to measure overall disparities in pregnancy outcome, incorporating data from the many race and ethnic groups that compose the US population, to improve understanding of how disparities may have changed over time. We used Birth Cohort Linked Birth–Infant Death Data Files from US Vital Statistics from 1989–1990 and 2005–2006 to examine multigroup indices of racial and ethnic disparities in the overall infant mortality rate (IMR), preterm birth rate, and gestational age–specific IMRs. We calculated selected absolute and relative multigroup disparity metrics weighting subgroups equally and by population size. Overall IMR decreased on the absolute scale, but increased on the population-weighted relative scale. Disparities in the preterm birth rate decreased on both the absolute and relative scales, and across equally weighted and population-weighted indices. Disparities in preterm IMR increased on both the absolute and relative scales. Infant mortality is a common bellwether of general and maternal and child health. Despite significant decreases in disparities in the preterm birth rate, relative disparities in overall and preterm IMRs increased significantly over the past 20 years.
