Analysis of umpires' age at death suggests that fears regarding risks of their profession are unfounded.
The on-field death 4 years ago of a veteran Major League Baseball (MLB) umpire raised questions regarding the mortality risks of this profession.
To determine if the life expectancy of MLB umpires differs from that of the general population.
Ages of death of MLB umpires were determined, and the differences between the ages of death and age-adjusted life expectancies were calculated. T-score analysis was performed on these differences. Correlational analysis was also done on many different factors, including umpire debut year, debut age, life expectancy at debut, and length of career.
No significant difference was found between the age at death of MLB umpires and their age-adjusted life expectancy. Correlational analyses showed that only length of career correlated with age at death.
MLB umpiring is not associated with a shortened life expectancy. While this is most likely attributable to the profession having no inherent risk, it could also be explained by inherent risks being overcome by yet unidentified, unique factors.
对裁判员死亡年龄的分析表明，对其职业风险的担忧是没有根据的。
4年前一位资深美国职业棒球大联盟（MLB）裁判员在赛场上死亡，引发了对该职业死亡风险的质疑。
确定MLB裁判员的预期寿命是否与普通人群不同。
确定MLB裁判员的死亡年龄，并计算死亡年龄与年龄调整后的预期寿命之间的差异。对这些差异进行T分数分析。还对许多不同因素进行了相关性分析，包括裁判员首次亮相年份、首次亮相年龄、首次亮相时的预期寿命以及职业生涯长度。
MLB裁判员的死亡年龄与其年龄调整后的预期寿命之间未发现显著差异。相关性分析表明，只有职业生涯长度与死亡年龄相关。
MLB裁判工作与预期寿命缩短无关。虽然这很可能归因于该职业没有内在风险，但也可以解释为尚未确定的独特因素克服了内在风险。
