Background: Research has shown that long work hours and overtime are associated with health impairment, including stress, burnout, and overall health. However, this has not been thoroughly assessed among stone, sand, and gravel mine workers. As such, this study examined whether significant differences in stress, burnout, and overall health existed among workers that worked different hours each week. Methods: ANOVA analyses were completed for the outcome variables (stress, burnout, and health status). Each analysis included three categorical independent variables: age, sex, and work hours. Age and sex were control variables. BMI was added to the health status analysis as an additional control variable. Results: There were significant differences between work hour groups for all three outcomes. Post hoc analyses determined that workers working >60 h/week had more stress, more burnout, and lower health. Differences were not found between age or sex. There were no differences in health status for different BMI groups, but the interaction of BMI and work hours was significant. Conclusions: Working more than 60 h per week was problematic. Mine and safety administrators should enact programs to protect and promote worker health, particularly among those working long hours, especially if more than 60 h per week.
研究表明，工作时间长和加班与健康损害有关，包括压力、倦怠和整体健康。然而，在石材、沙子和砾石矿工人中，这并没有得到彻底评估。因此，本研究旨在检验每周工作时间不同的工人之间是否存在压力、倦怠和整体健康方面的显著差异。
对（压力、倦怠和健康状况）这三个结果变量进行 ANOVA 分析。每个分析都包含三个分类自变量：年龄、性别和工作时间。年龄和性别是控制变量。BMI 被添加到健康状况分析中作为额外的控制变量。
所有三个结果在工作时间组之间都存在显著差异。事后分析确定每周工作时间>60 小时的工人压力更大、倦怠程度更高、健康状况更差。年龄或性别差异不明显。不同 BMI 组的健康状况没有差异，但 BMI 和工作时间的相互作用是显著的。
每周工作时间超过 60 小时是有问题的。矿山和安全管理人员应制定保护和促进工人健康的计划，特别是针对那些工作时间长的工人，尤其是每周工作时间超过 60 小时的工人。
