Musculoskeletal shoulder load among baggage handlers measured by combining duration and intensity based on biomechanical and epidemiological information may be a stronger predictor of subacromial shoulder disorders than baggage handler seniority. In 2012, a cohort of baggage handlers employed at Copenhagen Airport in 1990-2012, and a cohort of unskilled otherwise employed men answered a survey. Self-reported information on work tasks during employment in the airport in combination with work task specific biomechanically modelled forces in the shoulder joint was used to estimate shoulder load. Exposure measures were accumulated shoulder abduction moment, accumulated shoulder compression force, accumulated supraspinatus force and baggage handler seniority. The outcome was subacromial shoulder disorder registered in the Danish National Patient Register. When analyses were adjusted by all confounders except age, exposure variables showed close to significant associations with subacromial shoulder disorder. Results could not confirm our hypothesis that combined information on work task duration and shoulder load intensity was stronger associated with subacromial shoulder disorder than seniority. Practitioner Summary: In this study we sought to identify if the exposure to work-related musculoskeletal shoulder loading including duration and intensity among baggage handlers was associated with subacromial shoulder disorder. We found that there was an association but this was not stronger than that between baggage handler seniority and subacromial shoulder disorder.
根据生物力学和流行病学信息，结合工作时长和强度来衡量行李搬运工的肩部肌肉骨骼负荷，可能比行李搬运工的工龄更能有力地预测肩峰下肩部疾病。2012年，一组1990 - 2012年受雇于哥本哈根机场的行李搬运工，以及一组从事其他非技术工作的男性回答了一项调查。将机场工作期间自我报告的工作任务信息与肩关节中特定工作任务的生物力学建模力相结合，以估计肩部负荷。暴露测量指标包括累计肩外展力矩、累计肩部压缩力、累计冈上肌力量和行李搬运工工龄。结果是丹麦国家患者登记册中记录的肩峰下肩部疾病。当分析对除年龄外的所有混杂因素进行调整时，暴露变量与肩峰下肩部疾病显示出接近显著的关联。结果未能证实我们的假设，即关于工作任务持续时间和肩部负荷强度的综合信息与肩峰下肩部疾病的关联比工龄更强。从业者总结：在本研究中，我们试图确定行李搬运工接触与工作相关的肩部肌肉骨骼负荷（包括持续时间和强度）是否与肩峰下肩部疾病有关。我们发现存在关联，但这种关联并不比行李搬运工工龄与肩峰下肩部疾病之间的关联更强。
