The workforce ageing and the relationship between workers’ age and work accidents are factors of great concern worldwide. The aim of this article is twofold: to explore the association between workers’ age and work accidents registered by one mutual insurance company between 2015 and 2019; and to analyze the odds ratio (OR) trend of fatal accidents and accidents causing lost workdays over the same period. The odds for fatal accidents and for accidents causing lost workdays were calculated for younger and older workers through a logistic regression stratified by gender. The Prais-Winsten regression was used to evaluate the OR evolution trend in the study period. During 2015–2019, a total of 625,050 work accidents were registered. Workers aged between 45 and 99 years old in the event of a work accident are more likely to die (OR = 1.92) and be temporarily disabled (OR = 1.21) than workers aged between 18 and 44 years. In the comparison between workers aged 18–29 and 60–99, the OR for the latter increases up to 3.43 in the case of death in a work-related accident, and to 1.46 for temporary disability. Older workers are more likely to have fatal and disabling accidents than younger workers and the accidents are associated with higher costs. Furthermore, during the analyzed period, the observed OR trend was stable. Therefore, we conclude that strategic actions are needed to decrease the observed trends.

劳动力老龄化以及工人年龄与工伤事故之间的关系是世界范围内非常关注的因素。本文的目的有两个：探索工人年龄与 2015 年至 2019 年间一家相互保险公司登记的工伤事故之间的关联；并分析同期致命事故和造成损失工作日的事故的优势比（OR）趋势。通过按性别分层的逻辑回归计算了年轻和年长工人的致命事故和导致工作日损失的事故的几率。Prais-Winsten 回归用于评估研究期间的 OR 演变趋势。2015-2019 年，共登记了 625,050 起工伤事故。发生工伤事故时，年龄在 45 至 99 岁之间的工人更有可能死亡（OR = 1. 92) 并且比 18 至 44 岁的工人暂时残疾 (OR = 1.21)。在 18-29 岁和 60-99 岁工人之间的比较中，后者的 OR 在与工作有关的事故死亡的情况下增加到 3.43，在暂时残疾的情况下增加到 1.46。与年轻工人相比，老年工人更容易发生致命和致残事故，而且事故成本更高。此外，在分析期间，观察到的 OR 趋势是稳定的。因此，我们得出结论，需要采取战略行动来减少观察到的趋势。与年轻工人相比，老年工人更容易发生致命和致残事故，而且事故成本更高。此外，在分析期间，观察到的 OR 趋势是稳定的。因此，我们得出结论，需要采取战略行动来减少观察到的趋势。与年轻工人相比，老年工人更容易发生致命和致残事故，而且事故成本更高。此外，在分析期间，观察到的 OR 趋势是稳定的。因此，我们得出结论，需要采取战略行动来减少观察到的趋势。
