To examine if age differences in the consequences of work injury are exacerbated when occupational physical demands are higher.
A secondary analysis of workers' compensation claims in British Columbia (N = 373,672). Regression models examined the relationship between age and health care expenditures, days of wage replacement and the occurrence of long-term-disability following a work-related injury in occupations with lower and higher physical demands. Models were adjusted for individual and injury related covariates.
Older age and higher occupational physical demands were associated with worse work-injury outcomes. The relationship between age and each outcome was not exacerbated when occupational physical demands were higher compared to when they were lower. Counter to our hypotheses age differences in health care expenditures were smaller among women in more demanding occupations.
In this study, we found no evidence that the relationship between age and the consequences of work injury is exacerbated when physical occupational demands are high.
探讨当职业体力需求较高时，工伤后果的年龄差异是否会加剧。
对不列颠哥伦比亚省的工伤赔偿申请进行二次分析（N = 373,672）。回归模型研究了年龄与医疗保健支出、工资替代天数以及体力需求较低和较高职业中工伤后长期残疾发生率之间的关系。模型针对个体和与损伤相关的协变量进行了调整。
年龄较大和职业体力需求较高与较差的工伤结果相关。与体力需求较低时相比，体力需求较高时，年龄与每种结果之间的关系并未加剧。与我们的假设相反，在体力要求较高的职业中，女性在医疗保健支出方面的年龄差异较小。
在本研究中，我们没有发现证据表明当职业体力需求较高时，年龄与工伤后果之间的关系会加剧。
