Breast cancer mortality rates vary across ethnic groups in Israel, where protective factors such as high fertility and breastfeeding rates may be moderated by socioeconomic factors and mammography rates. We aim to investigate disparities in breast cancer mortality between Jewish and Muslim Arab women in Israel and examine how sociodemographic variables and number of children are associated with mortality. Our retrospective follow-up study uses data from the Israeli Central Bureau of Statistics and multivariable Cox regression models, adjusting for age, number of children, country of origin, locality size, and socioeconomic status. Compared to Jewish women, Muslim Arab women exhibited lower breast cancer mortality rates. However, after adjusting for multiple sociodemographic variables, no significant differences persisted between Jewish and Muslim Arab women. Having more than three children was associated with lower mortality among Muslim Arab women but not among Jewish women. European/American origin, larger localities, and medium socioeconomic status were associated with higher mortality. Sociodemographic factors may therefore explain the disparities in breast cancer mortality between Jewish and Muslim Arab women in Israel. Targeted intervention programs that consider the unique characteristics and risk factors of different ethnic groups are needed to reduce disparities and improve outcomes.
在以色列，不同族裔群体的乳腺癌死亡率存在差异，其中高生育率和母乳喂养率等保护性因素可能受到社会经济因素和乳腺X光检查率的调节。本研究旨在探讨以色列犹太女性和穆斯林阿拉伯女性之间乳腺癌死亡率的差异，并分析社会人口学变量及子女数量与死亡率之间的关联。我们采用回顾性随访研究设计，利用以色列中央统计局的数据，通过多变量Cox回归模型进行分析，并对年龄、子女数量、原籍国、居住地规模及社会经济地位等因素进行了调整。结果显示，与犹太女性相比，穆斯林阿拉伯女性的乳腺癌死亡率较低。然而，在调整多项社会人口学变量后，犹太女性和穆斯林阿拉伯女性之间的死亡率差异不再显著。对于穆斯林阿拉伯女性而言，拥有三个以上子女与较低的死亡率相关，但在犹太女性中未观察到类似关联。欧洲/美洲原籍、较大规模的居住地以及中等社会经济地位与较高的死亡率相关。因此，社会人口学因素可能解释了以色列犹太女性和穆斯林阿拉伯女性之间乳腺癌死亡率的差异。为减少差异并改善预后，需要针对不同族裔群体的独特特征和风险因素制定有针对性的干预计划。
