We compared the mortality rate of sumo wrestlers with that of the contemporaneous Japanese male population, and inferred the usefulness of an index for predicting longevity in sumo wrestlers. The standardized mortality ratios (SMR) for sumo wrestlers were very high in each period, and also high for ages from 35 to 74. Cox's proportional hazards model analysis revealed that the variables in "nyuumaku" entry year and BMI were statistically significant (p < 0.05) factors in mortality. In the survival curves, the lower BMI group had good life expectancy compared with the higher BMI group. In conclusion, the higher rate of mortality in sumo wrestlers seems to be due to the markedly higher rate of mortality from 35 to 74 years old. In sumo wrestlers, also, this study provides evidence that the higher overweight groups have substantially higher risks for mortality.
我们将相扑选手的死亡率与同时期的日本男性人口死亡率进行了比较，并推断出一个预测相扑选手长寿的指标的有用性。在每个时期，相扑选手的标准化死亡率（SMR）都非常高，在35至74岁年龄段也很高。Cox比例风险模型分析显示，“入幕”年份和体重指数（BMI）的变量是死亡率方面具有统计学意义（p < 0.05）的因素。在生存曲线中，BMI较低的组与BMI较高的组相比，预期寿命较好。总之，相扑选手较高的死亡率似乎是由于35至74岁年龄段显著更高的死亡率所致。在相扑选手中，本研究也提供了证据表明超重程度较高的群体有更高的死亡风险。
