In Brazil, inequalities in access may interfere with cancer care. This study aimed to evaluate the influence of race on breast cancer mortality in the state of São Paulo, from 2000 to 2017, contextualizing with other causes of death. A population-based retrospective study using mortality rates, age and race as variables. Information on deaths was collected from the Ministry of Health Information System. Only white and black categories were used. Mortality rates were age-adjusted by the standard method. For statistical analysis, linear regression was carried out. There were 60,940 deaths registered as breast cancer deaths, 46,365 in white and 10,588 in black women. The mortality rates for 100,000 women in 2017 were 16.46 in white and 9.57 in black women, a trend to reduction in white (p = 0.002), and to increase in black women (p = 0.010). This effect was more significant for white women (p < 0.001). The trend to reduction was consistent in all age groups in white women, and the trend to increase was observed only in the 40–49 years group in black women. For ‘all-cancer causes’, the trend was to a reduction in white (p = 0.031) and to increase in black women (p < 0.001). For ‘ill-defined causes’ and ‘external causes’, the trend was to reduce both races (p < 0.001). The declared race influenced mortality rates due to breast cancer in São Paulo. The divergences observed between white and black women also were evident in all cancer causes of death, which may indicate inequities in access to highly complex health care in our setting.

巴西圣保罗 2000 年至 2017 年乳腺癌死亡率的种族差异:一项基于人群的回顾性研究

在巴西,获取机会的不平等可能会干扰癌症治疗。本研究旨在评估种族对 2000 年至 2017 年圣保罗州乳腺癌死亡率的影响,并结合其他死亡原因。一项使用死亡率、年龄和种族作为变量的基于人群的回顾性研究。死亡信息是从卫生部信息系统收集的。只使用了白色和黑色类别。通过标准方法对死亡率进行年龄调整。对于统计分析,进行了线性回归。有 60,940 人死于乳腺癌,其中白人女性 46,365 人,黑人女性 10,588 人。2017 年 100,000 名女性的死亡率分别为 16.46 和 9.57,白人女性死亡率下降(p = 0.002),黑人女性死亡率增加(p = 0.010)。这种效果对白人女性更为显着(p < 0.001)。白人女性所有年龄组的减少趋势一致,仅在 40-49 岁黑人女性组中观察到增加的趋势。对于“所有癌症原因”,趋势是白人女性减少(p = 0.031),黑人女性增加(p < 0.001)。对于“不明确的原因”和“外部原因”,趋势是减少两个种族(p < 0.001)。宣布的种族影响了圣保罗的乳腺癌死亡率。在所有癌症死因中观察到的白人和黑人女性之间的差异也很明显,这可能表明在我们的环境中获得高度复杂的医疗保健方面存在不平等。仅在 40-49 岁的黑人女性群体中观察到增加的趋势。对于“所有癌症原因”,趋势是白人女性减少(p = 0.031),黑人女性增加(p < 0.001)。对于“不明确的原因”和“外部原因”,趋势是减少两个种族(p < 0.001)。宣布的种族影响了圣保罗的乳腺癌死亡率。在所有癌症死因中观察到的白人和黑人女性之间的差异也很明显,这可能表明在我们的环境中获得高度复杂的医疗保健方面存在不平等。仅在 40-49 岁的黑人女性群体中观察到增加的趋势。对于“所有癌症原因”,趋势是白人女性减少(p = 0.031),黑人女性增加(p < 0.001)。对于“不明确的原因”和“外部原因”,趋势是减少两个种族(p < 0.001)。宣布的种族影响了圣保罗的乳腺癌死亡率。在所有癌症死因中观察到的白人和黑人女性之间的差异也很明显,这可能表明在我们的环境中获得高度复杂的医疗保健方面存在不平等。001)。宣布的种族影响了圣保罗的乳腺癌死亡率。在所有癌症死因中观察到的白人和黑人女性之间的差异也很明显,这可能表明在我们的环境中获得高度复杂的医疗保健方面存在不平等。001)。宣布的种族影响了圣保罗的乳腺癌死亡率。在所有癌症死因中观察到的白人和黑人女性之间的差异也很明显,这可能表明在我们的环境中获得高度复杂的医疗保健方面存在不平等。
