Musculoskeletal pain is common in the working population and may affect the work ability, especially among those with high physical work demands. This study investigated the association between physical work demands and work ability in workers with musculoskeletal pain. Workers with physically demanding jobs (n = 5377) participated in the Danish Work Environment Cohort Study in 2010. Associations between physical work ability and various physical work demands were modeled using cumulative logistic regression analyses while controlling for possible confounders. In the fully adjusted model, bending and twisting/turning of the back more than a quarter of the workday (reference: less than a quarter of the workday) was associated with higher odds of lower work ability in workers with low-back pain (OR: 1.38, 95% CI: 1.09–1.74) and neck-shoulder pain (OR: 1.29, 95% CI: 1.01–1.64). When adding up the different types of demands, being exposed to two or more physical work demands for more than a quarter of the workday was consistently associated with lower work ability. Work that involves high demands of the lower back seems especially problematic in relation to work ability among physical workers with musculoskeletal pain. Regardless of the specific type of physical work demand, being exposed to multiple physical work demands for more than a quarter of the workday was also associated with lower work ability.

肌肉骨骼疼痛工人的体力劳动需求与工作能力之间的关联：横断面研究

肌肉骨骼疼痛在工作人群中很常见，并且可能会影响工作能力，尤其是对身体有较高要求的人。本研究调查了肌肉骨骼疼痛工人的体力劳动需求与工作能力之间的关系。有体力劳动的工人（n = 5377）参加了2010年的丹麦工作环境队列研究。在控制可能的混杂因素的同时，使用累积逻辑回归分析对体力劳动能力与各种体力劳动需求之间的关联进行了建模。在完全调整的模型中，腰部弯曲和扭曲/转弯超过工作日的四分之一（参考：少于工作日的四分之一）与腰痛（OR）较低的工人工作能力降低的可能性较高相关：1.38，95％CI：1.09–1。74）和肩颈疼痛（OR：1.29，95％CI：1.01-1.64）。当将不同类型的需求相加时，在两个或两个以上的身体工作需求中暴露超过四分之一的工作日，总是导致工作能力降低。在肌肉骨骼疼痛的体力劳动者中，涉及下背部要求较高的工作似乎对工作能力而言尤其成问题。无论体力劳动需求的具体类型如何，在超过四分之一的工作日中承受多种体力劳动需求也与较低的工作能力有关。在肌肉骨骼疼痛的体力劳动者中，对腰背要求很高的工作似乎特别有问题。无论体力劳动需求的具体类型如何，在超过四分之一的工作日中承受多种体力劳动需求也与较低的工作能力有关。在肌肉骨骼疼痛的体力劳动者中，对腰背要求很高的工作似乎特别有问题。无论体力劳动需求的具体类型如何，在超过四分之一的工作日中承受多种体力劳动需求也与较低的工作能力有关。
