In the US, the non-Hispanic Black infant mortality rate exceeds the rate among non-Hispanic Whites by more than two-fold. To explore factors underlying this persistent disparity, we employed a mixed methods approach with concurrent quantitative and qualitative data collection and analysis. Eighteen women participated in interviews about their experience of infant loss. Several common themes emerged across interviews, grouped by domain: individual experiences (trauma, grieving and counseling; criminalization); negative interactions with healthcare providers and the healthcare system; and broader contextual factors. Concurrently, we estimated the Black infant mortality rate (deaths per 1000 live births) using linked live birth-infant death records from 2010 to 2013 in every metropolitan statistical area in the US. Poisson regression examined how contextual indicators of population health, socioeconomic conditions of the Black population, and features of the communities in which they live were associated with Black infant mortality and inequity in Black-White infant mortality rates across 100 metropolitan statistical areas with the highest Black infant mortality rates. We used principal components analysis to create a Birth Equity Index in order to examine the collective impact of contextual indicators on Black infant mortality and racial inequity in mortality rates. The association between the Index and Black infant mortality was stronger than any single indicator alone: in metropolitan areas with the worst social, economic, and environmental conditions, Black infant mortality rates were on average 1.24 times higher than rates in areas where conditions were better (95% CI = 1.16, 1.32). The experiences of Black women in their homes, neighborhoods, and health care centers and the contexts in which they live may individually and collectively contribute to persistent racial inequity in infant mortality.
在美国,非西班牙裔黑人婴儿死亡率比非西班牙裔白人高出两倍多。为了探究造成这种持续差距的因素,我们采用了一种混合方法,同时进行定量和定性数据的收集与分析。18名女性参与了关于她们婴儿夭折经历的访谈。访谈中出现了几个共同主题,按领域分组如下:个人经历(创伤、悲伤与咨询;被定罪);与医疗服务提供者及医疗系统的负面互动;以及更广泛的背景因素。同时,我们利用2010年至2013年美国每个大都市统计区的出生与婴儿死亡记录链接数据,估算了黑人婴儿死亡率(每1000例活产中的死亡数)。泊松回归分析考察了人口健康的背景指标、黑人人口的社会经济状况以及他们所居住社区的特征,与100个黑人婴儿死亡率最高的大都市统计区的黑人婴儿死亡率以及黑人与白人婴儿死亡率不平等之间的关联。我们使用主成分分析创建了一个生育公平指数,以检验背景指标对黑人婴儿死亡率和死亡率种族不平等的综合影响。该指数与黑人婴儿死亡率之间的关联比任何单一指标都更强:在社会、经济和环境条件最差的大都市地区平均而言,黑人婴儿死亡率比条件较好地区高出1.24倍(95%置信区间=1.16,1.32)。黑人女性在家庭、社区和医疗中心的经历以及她们所处的环境,可能单独或共同导致婴儿死亡率方面持续存在的种族不平等。
