While the prevalence of musculoskeletal disorders has recently increased among Korean workers employed in highly physically and psychologically demanding jobs, the relation among these domains remains relatively unexplored. We examined 2,037 subway workers in Seoul, that collected data via questionnaire survey on musculoskeletal symptoms and the work environment, administered in 2009, 2012, and 2015. Generalized estimating equation (GEE) analysis was used for statistical analysis. After conducting GEE analysis by adjusting for the sociodemographic and occupational characteristics, we found the prevalence of musculoskeletal symptoms significantly increased in cases with high Depression, Anxiety and Stress Scales (DASS) scores compared with low DASS scores, especially on shift workers. An integrated management method that considers ergonomic and mental health factors, should be used to better manage musculoskeletal symptoms in subway workers.

重复测量研究地铁工人的肌肉骨骼症状与心理健康之间的关系。

尽管最近在身体和心理上要求很高的工作的韩国工人中，肌肉骨骼疾病的患病率有所上升，但这些领域之间的关系仍未得到充分探索。我们调查了首尔的2037名地铁工人，他们通过问卷调查收集了有关2009年，2012年和2015年进行的肌肉骨骼症状和工作环境的调查。我们使用广义估计方程（GEE）分析进行统计分析。通过调整社会人口统计学和职业特征进行GEE分析后，我们发现与低DASS得分相比，抑郁，焦虑和压力量表（DASS）得分高的患者，尤其是在轮班工人中，肌肉骨骼症状的患病率显着增加。
