Abstract：Objective To investigate the prevalence of musculoskeletal disorders (MSDs) among coal miners in Xinjiang, and to analyze the impact of occupational stress and psychological disorders on MSDs. Methods With a stratified cluster sampling method, 1,230 first-line coal miners were enrolled to serve as the study subjects. The current status of MSDs in the subjects was evaluated by self-filled general information questionnaire, effort-reward imbalance questionnaire (ERI),Symptom Checklist-90(SCL-90)and MSDs questionnaire. Results A total of 1,230 coal miners were surveyed in this study, and 805 of them had MSDs, with a prevalence rate of 65.45%. There were statistically significant differences in the prevalence rate of MSDs among coal miners with different genders, ages, years of service, shifts, types of work in production, educational backgrounds, and average monthly incomes (χ2=8.989, χ2=76.602, χ2=40.054, χ2=9.617, χ2=38.671, χ2=127.846, χ2=33.154, all P<0.05). 615 workers had occupational stress, with a prevalence rate of 50.00%. 630 workers suffered from psychological disorders, with a prevalence rate of 51.22%. The prevalence rates of MSDs showed statistically significant differences between different occupational stress groups as well as between different psychological disorders groups (χ2=11.681, χ2=22.059, both P<0.05). Logistic regression analysis revealed that females (OR=2.022, 95%CI:1.292-3.159), age (OR=1.532, 95%CI:1.035-2.266), coal-mining workers (OR=1.801, 95%CI:1.307-2.409), having a educational background of junior middle school and below (OR=9.453, 95%CI:6.529-13.687), occupational stress (OR=1.364, 95%CI:1.030-1.806), psychological disorders (OR=1.826, 95%CI:1.361-2.449) were risk factors for MSDs in the coal miners (all P<0.05). Conclusion This study shows that the current situation of occurrence of MSDs among the coal miners is not optimistic. Occupational stress and psychological disorders can increase the risk of occurrence of MSDs.
