Abstract

This paper has two objectives. First, we examine the Black-White disparity in the U.S. infant mortality rate (IMR) between 1995 and 2009, and explore the influence of socioeconomic characteristics (e.g., marital status, education, and prenatal care) on this racial gap. Second, we calculate projected IMRs and compare these results to the objectives of the Healthy People 2020 program. Descriptive statistics were calculated and linear regression models were conducted using data from the Centers for Disease Control and Prevention's linked birth and infant death files. Between 1995 and 2009, the IMR declined by 11.9 % for White mothers and 15.3 % for Black mothers. Among unmarried mothers, there was a 19.6 % decline for Whites and a 15.2 % reduction for Blacks. In comparison, among married mothers, there was a 19.3 % decline for Whites and an 18.1 % reduction for Blacks. For both Blacks and Whites, the largest percent declines occurred among women with the lowest and highest levels of education. For both racial groups, those with no prenatal care had the highest IMRs. Despite these significant declines, educated White women are the only group predicted to reach the Healthy People 2020 objective of an IMR lower than 6.0 infant deaths per 1,000 live births. The predicted IMR for highly educated Black women in 2020 is 10.6, and the projected rates for Black mothers with low education levels are even higher. Although the IMR has declined since 1995, the racial disparity between Blacks and Whites will most likely persist through 2020. Whereas educated White mothers are projected to meet the Healthy People 2020 IMR goal, other groups will fall short. The racial disparity persists even when mothers are grouped by marital status, educational attainment, and access to care. Future policies and prevention programs should address these racial disparities.

摘要

本文有两个目标。首先,我们考察了 1995 年至 2009 年美国白人和黑人婴儿死亡率(IMR)之间的差距,并探讨了社会经济特征(如婚姻状况、教育程度和产前保健)对这一种族差距的影响。其次,我们计算了预计的 IMR,并将这些结果与《健康人民 2020 计划》的目标进行了比较。使用疾病控制和预防中心的链接出生和婴儿死亡档案中的数据计算了描述性统计数据并进行了线性回归模型。在 1995 年至 2009 年间,白人母亲的 IMR 下降了 11.9%,黑人母亲的 IMR 下降了 15.3%。在未婚母亲中,白人母亲的 IMR 下降了 19.6%,黑人母亲的 IMR 下降了 15.2%。相比之下,在已婚母亲中,白人母亲的 IMR 下降了 19.3%,黑人母亲的 IMR 下降了 18.1%。对于黑人和白人来说,最大的百分比下降发生在教育程度最低和最高的女性中。对于两个种族群体,没有产前保健的女性的 IMR 最高。尽管有这些显著的下降,但受过教育的白人女性是唯一预计能达到《健康人民 2020 计划》中 IMR 低于每 1000 例活产婴儿 6.0 例的目标的群体。预计 2020 年受过高等教育的黑人女性的 IMR 为 10.6,而教育程度较低的黑人母亲的预计比率甚至更高。尽管自 1995 年以来 IMR 有所下降,但黑人与白人之间的种族差距很可能会持续到 2020 年。受过教育的白人母亲预计将达到《健康人民 2020 计划》的 IMR 目标,而其他群体则无法达到。即使将母亲按婚姻状况、教育程度和获得保健的机会分组,种族差距仍然存在。未来的政策和预防计划应解决这些种族差异。
