Data are presented on mortality from neoplasms as determined from death certificates in a cohort of 8393 college men, according to athletic status in college. Major athletes (lettermen) died significantly more often from neoplasms than nonathletes. Mean age at death from neoplasms (underlying cause) was significantly lower in major athletes than in both minor athletes and nonathletes. After matching major athletes with nonathletes of comparable body size (height and weight), differences in proportional mortality and mean age at death from neoplasms persisted, although not statistically significant for the smaller samples. Correlation coefficients (Pearson r) and partial r's between weight in college and age at death from neoplasms were negative but of low magnitude. Some possible explanations for the differences between major athletes and nonathletes are discussed.
根据大学期间的运动状况，呈现了一组8393名大学男性队列中由死亡证明确定的肿瘤死亡率数据。主要运动员（有运动员荣誉的学生）死于肿瘤的频率显著高于非运动员。主要运动员因肿瘤（根本原因）死亡的平均年龄显著低于次要运动员和非运动员。在将主要运动员与体型（身高和体重）相当的非运动员进行匹配后，肿瘤比例死亡率和死亡平均年龄的差异仍然存在，尽管对于较小样本而言差异无统计学意义。大学时的体重与肿瘤死亡年龄之间的相关系数（皮尔逊r）和偏相关系数为负，但幅度较小。讨论了主要运动员和非运动员之间差异的一些可能解释。
