摘要

本研究旨在验证风险因素对巴西内陆地区工人大腿、腿部和足部 WMSDs 症状的直接和间接影响。研究测试了一个结构方程模型(SEM),该模型描述了风险因素与 WMSDs 之间的假设关系。研究采用问卷调查的方式收集了 420 名工人的社会人口、职业、生物力学和心理社会因素以及疼痛症状等方面的数据。结果显示,不同的因素会直接影响大腿、腿部和足部。将下肢保持在不舒服的姿势会增加大腿(β = 0.219;p 值为 0.001)、腿(β = 0.223;p 值为 0.001)和足(β = 0.158;p 值为 0.01)发生 WMSD 的几率。大多数心理社会因素会减轻心理社会压力,而心理社会压力又会直接减轻大腿(β = -0.502;p 值为 0.001)、腿部(β = -0.315;p 值为 0.01)和足部(β = -0.246;p 值为 0.01)的 WMSD 症状。研究还发现,一些因素对腿部的 "另一份工作"(β = -0.246;p 值为 0.01)和脚部的努力(β = 0.146;p 值为 0.05)有独特的影响。结论是,多种因素会影响下肢 WMSDs 的发展。这些研究结果有助于加深人们对 WMSDs 病因的认识,并有助于改善研究对象的工作条件。因此,管理人员、健康、工效学和职业安全专业人员可以利用这些研究结果制定更精确的策略,以减少 WMSDs 对工人的影响。

Risk factors for work-related musculoskeletal disorders among workers in Brazil: A structural equation model approach

This study aimed to verify the direct and indirect influence of risk factors on the symptoms of WMSDs in the thigh, leg, and foot among workers in the inner regions of Brazil. Research tested a structural equation model (SEM) that describes hypothetical relationships between risk factors and WMSDs. Questionnaires were used to collect data on sociodemographic, occupational, biomechanical, and psychosocial factors, and pain symptoms about 420 workers. The results showed that different factors directly affect the thigh, leg, and foot. Maintaining the lower limbs in uncomfortable positions increases the chances of developing WMSDs in the thigh (β = 0.219; p-value <0.001), leg (β = 0.223; p-value <0.001), and foot (β = 0.158; p-value <0.01). Most psychosocial factors attenuate psychosocial stress, which in turn directly alleviates WMSD symptoms in the thigh (β = −0.502; p-value <0.001), leg (β = −0.315; p-value <0.01), and foot (β = −0.246; p-value <0.01). Factors were also found to uniquely affect aspects such as “another job” (β = −0.246; p-value <0.01) in the leg and effort (β = 0.146; p-value <0.05) in the foot. It was concluded that multiple factors influence the development of WMSDs in the lower limbs. These findings contribute to the existing knowledge on the causes of WMSDs and can help improve working conditions for the population under study. Therefore, managers and health, ergonomics, and occupational safety professionals can use the findings to develop more precise strategies to reduce the impacts of WMSDs on workers.
