To estimate the associations of psychosocial factors with work-related musculoskeletal disorders (WMSDs), providing scientific evidence for targeted strategies for the prevention of WMSDs in Chinese coal miners.
A total of 500 coal miners were consecutively enrolled to this cross-sectional study. The prevalence of WMSDs was assessed using the Standardized Nordic Questionnaire. Logistic regression analyses were conducted to estimate the associations between psychosocial factors and WMSDs.
Among coal miners, of 277 coal miners, 61% self-reported WMSDs in a 12-month period. Especially, back pain was the most frequent musculoskeletal symptom. WMSDs were statistically correlated with high job demands (OR = 1.3, 95%CI: 1.3 ∼ 3.5), low job control (OR = 1.6, 95%CI: 1.0 ∼ 2.4), low level of interpersonal relations (OR = 1.9, 95%CI: 1.2 ∼ 3.0) and low job satisfaction (OR = 1.6, 95%CI: 1.0 ∼ 2.4).
The results of this study demonstrate psychosocial factors were associated with WMSDs among coal miners, and psychosocial factors be considered for the prevention of WMSDs.
评估社会心理因素与工作相关肌肉骨骼疾病（WMSDs）之间的关联，为中国煤矿工人预防WMSDs的针对性策略提供科学依据。
共有500名煤矿工人连续纳入本横断面研究。使用标准化北欧问卷评估WMSDs的患病率。进行逻辑回归分析以评估社会心理因素与WMSDs之间的关联。
在煤矿工人中，277名煤矿工人中有61%在12个月内自我报告患有WMSDs。特别是，背痛是最常见的肌肉骨骼症状。WMSDs与高工作要求（OR = 1.3，95%CI：1.3 ∼ 3.5）、低工作控制（OR = 1.6，95%CI：1.0 ∼ 2.4）、低人际关系水平（OR = 1.9，95%CI：1.2 ∼ 3.0）和低工作满意度（OR = 1.6，95%CI：1.0 ∼ 2.4）在统计学上相关。
本研究结果表明社会心理因素与煤矿工人的WMSDs有关，预防WMSDs时应考虑社会心理因素。
