To evaluate the association between mortality-to-incidence ratios (MIRs) and health disparities.
In this study, we used the GLOBOCAN 2012 database to obtain the cancer incidence and mortality data for 57 countries, and combined this information with the World Health Organization (WHO) rankings and total expenditures on health/gross domestic product (e/GDP). The associations between variables and MIRs were analyzed by linear regression analyses and the 57 countries were selected according to their data quality.
The more developed regions showed high gastric cancer incidence and mortality crude rates, but lower MIR values than the less developed regions (0.64 0.80, respectively). Among six continents, Oceania had the lowest (0.60) and Africa had the highest (0.91) MIR. A good WHO ranking and a high e/GDP were significantly associated with low MIRs ( = 0.001 and = 0.001, respectively).
The MIR variation for gastric cancer would predict regional health disparities.
评估死亡率与发病率比值（MIR）与健康差异之间的关联。
本研究使用 GLOBOCAN 2012 数据库获取了 57 个国家的癌症发病率和死亡率数据，并将这些信息与世界卫生组织（WHO）的排名和卫生总支出/国内生产总值（e/GDP）进行了结合。通过线性回归分析对变量与 MIR 之间的关系进行了分析，并根据数据质量选择了 57 个国家。
较发达地区的胃癌粗发病率和死亡率较高，但 MIR 值较低（分别为 0.64 和 0.80）。在六大洲中，大洋洲的 MIR 值最低（0.60），非洲的 MIR 值最高（0.91）。较高的 WHO 排名和较高的 e/GDP 与较低的 MIR 值显著相关（=0.001 和=0.001）。
胃癌的 MIR 变化可以预测地区健康差异。
