We examined the association between job demand and occupational injury among older workers.
Participants were workers aged 50+ enrolled in the Health and Retirement Study, 2010 to 2014. Participants reported physical ability within three domains: physical effort, stooping/kneeling/crouching, and lifting. To measure subjective job demand, participants rated their job's demands within domains. We generated objective job demand measures through the Occupational Information Network (ONET). Using Poisson regression, we modeled the association between physical ability, job demand, and self-reported occupational injury. A second model explored interaction between job demand and physical ability.
The injury rate was 22/1000 worker-years. Higher job demand was associated with increased injury risk. Within high job demands, lower physical ability was associated with increased injury risk.
Older workers whose physical abilities do not meet job demands face increased injury risk.
我们研究了老年工人的工作需求与职业伤害之间的关联。
参与者为2010年至2014年参加健康与退休研究的50岁及以上工人。参与者报告了三个方面的身体能力：体力、弯腰/跪/蹲以及提举。为衡量主观工作需求，参与者对其工作在各方面的需求进行评分。我们通过职业信息网络（ONET）生成客观工作需求指标。使用泊松回归，我们对身体能力、工作需求和自我报告的职业伤害之间的关联进行建模。第二个模型探讨了工作需求与身体能力之间的相互作用。
伤害发生率为每1000工人年22例。较高的工作需求与伤害风险增加相关。在高工作需求情况下，较低的身体能力与伤害风险增加相关。
身体能力不符合工作需求的老年工人面临的伤害风险增加。
