The purpose of this paper is to explore 10-year trends in infant mortality rates (IMRs) from 2007 to 2016 for non-Hispanic (NH) blacks and NH whites by levels of sociodemographic characteristics such as maternal age, marital status, education, and access to prenatal care. Using data from the Centers for Disease Control and Prevention (CDC) Wonder Online database, descriptive statistics were performed, and a measure of disparity was calculated to illustrate racial differences in IMRs. Between 2007 and 2016, IMRs for NH blacks have declined at a faster rate (15.8%) compared to NH whites (13.5%). As for the selected sociodemographic indicators, reductions were observed for both racial groups for most age categories assessed, married and unmarried women, and for women with early or no access to prenatal care. For educational attainment levels, declines were observed for both racial groups for all levels except for high school graduate or GED and some college, in which increases were observed for NH white women. The measure of disparity illustrates the large racial gap in IMRs persists between NH blacks and NH whites. More structural and systemic mechanisms, including research and policies, are needed to address the disparities in IMRs.

本文的目的是通过社会人口统计学特征水平（如孕产妇年龄，婚姻状况，教育程度和生活水平）探讨2007年至2016年非西班牙裔（NH）黑人和NH白人的婴儿死亡率（IMR）的10年趋势。获得产前护理。使用疾病控制和预防中心（CDC）的Wonder Online数据库中的数据，进行了描述性统计，并计算了差异以说明IMR中的种族差异。在2007年至2016年之间，与NH白人（13.5％）相比，NH黑人的IMR下降速度更快（15.8％）。至于选定的社会人口统计学指标，在大多数年龄类别的已评估妇女，已婚和未婚妇女中，以及在早期或无法获得产前保健的妇女中，种族群体均下降了。对于受教育程度，除高中毕业生或GED和某些大学外，所有种族的两个种族的人均下降，其中NH白人妇女的人有所增加。差异的测量表明，在NH黑人和NH白人之间，IMR中存在较大的种族差距。需要更多的结构和系统性机制，包括研究和政策，以解决IMR中的差异。
