引言：本文介绍了美国50个最大的城市在2005年至2014年的每5年期间的种族特异性乳腺癌死亡率和相应的死亡率比率。方法：以美国最大的50个城市为分析单位。分子数据摘自死因为乳腺恶性肿瘤（ICD-10 = C50）的女性全国死亡档案。基于人口的分母是2010-2014年从美国人口普查局获得的。为了衡量种族差异，我们计算了每5年的黑人：白人比率（rr）和置信区间。为了确定差异随时间的变化是否具有统计学意义，我们计算了2005-2009年和2010-2014年黑人和白人比率之间相对百分比差异变化的双侧z分数。结果：在最近的时间点（2010-2014年），美国和24个城市的RR显著大于1.00。黑人：白人差距的变化在五个城市和美国都有统计学意义。在佐治亚州亚特兰大，百分比差异显著增加（从4.1到117.4,p < 0.001）；圣安东尼奥，德克萨斯州（从24.4到79.3,p = 0.034）；美国（从39.7降至43.1,p = 0.007）。田纳西州孟菲斯市的百分比差异显著下降（从111.0降至68.9,p = 0.043）；费城，PA（从43.1到23.5,p = 0.049）；波士顿，马萨诸塞州（从48.9到0.7,p = 0.022）。结论：该分析提供了截至2014年黑人和白人女性的最新城市乳腺癌死亡率数据，并揭示了在美国和美国43个最大城市中的24个，黑人女性死于乳腺癌的比例继续高于白人女性。然而，重要的是，在2005-2009年和2010-2014年之间，孟菲斯、波士顿和费城等几个城市的黑人和白人乳腺癌死亡率差距有所缩小。(C) 2016 Elsevier Ltd.版权所有。
Introduction: This paper presents race-specific breast cancer mortality rates and the corresponding rate ratios for the 50 largest U.S. cities for each of the 5-year intervals between 2005 and 2014.Methods: The 50 largest cities in the U.S. were the units of analysis. Numerator data were abstracted from national death files where the cause was malignant neoplasm of the breast (ICD-10 = C50) for women. Population-based denominators were obtained from the U.S. Census Bureau for 2010-2014. To measure the racial disparity, we calculated Black: White rate ratios (RRs) and confidence intervals for each 5-year period. To determine whether changes over time in the disparity were statistically significant, we calculated a 2-sided z score for the change in the relative percent difference between the Black and White rates for 2005-2009 and 2010-2014.Results: At the most recent time point (2010-2014), the RR was significantly greater than 1.00 in the US and 24 cities. The change in the Black: White disparity was statistically significant in five cities and the US. The percent difference increased significantly in Atlanta, GA (from 4.1 to 117.4, p < 0.001); San Antonio, TX (from 24.4 to 79.3, p = 0.034); and the US (from 39.7 to 43.1, p = 0.007). The percent difference decreased significantly in Memphis, TN (from 111.0 to 68.9, p = 0.043); Philadelphia, PA (from 43.1 to 23.5, p = 0.049); and Boston, MA (from 48.9 to 0.7, p = 0.022).Conclusion: This analysis provides updated city-level breast cancer mortality data for Black and White women through 2014, and reveals that in the US and 24 of the 43 largest US cities, Black women continue to die from breast cancer at a higher rate than their White counterparts. Importantly, however, a few cities, Memphis, Boston and Philadelphia, showed a decrease in the Black: White breast cancer mortality disparity between 2005-2009 and 2010-2014. (C) 2016 Elsevier Ltd.
