This study assessed the relationships of job tasks and living conditions with occupational injuries among coal miners. The sample included randomly selected 516 underground workers. They completed a standardized self-administred questionnaire. The data were analyzed via logistic regression method. The rate of injuries in the past two years was 29.8%. The job tasks with significant crude relative risks were: power hammer, vibrating hand tools, pneumatic tools, bent trunk, awkward work posture, heat, standing about and walking, job tasks for trunk and upper/lower limbs, pain caused by work, and muscular tiredness. Logistic model shows a strong relationship between the number of job tasks (JT) and injuries (adjusted ORs vs. JT 0-1: 2.21, 95%CI 1.27-3.86 for JT 2-6 and 3.82, 2.14-6.82 for JT>or=7), and significant ORs>or=1.71 for face work, not-good-health-status, and psychotropic drug use. Musculoskeletal disorders and certain personality traits were also significant in univariate analysis. Therefore job tasks and living conditions strongly increase the injuries, and occupational physicians could help workers to find remedial measures.
本研究评估了煤矿工人的工作任务和生活条件与职业伤害之间的关系。样本包括随机选取的516名井下工人。他们完成了一份标准化的自填式问卷。数据通过逻辑回归方法进行分析。过去两年的受伤率为29.8%。具有显著粗略相对风险的工作任务包括：气锤、振动手动工具、气动工具、躯干弯曲、工作姿势笨拙、高温、站立和行走、躯干及上肢/下肢的工作任务、工作引起的疼痛以及肌肉疲劳。逻辑模型显示工作任务数量（JT）与伤害之间存在密切关系（JT 2 - 6时，调整后的比值比与JT 0 - 1相比为2.21，95%置信区间为1.27 - 3.86；JT≥7时为3.82，2.14 - 6.82），面部工作、健康状况不佳和使用精神药物的比值比显著≥1.71。肌肉骨骼疾病和某些人格特质在单因素分析中也具有显著性。因此，工作任务和生活条件会大幅增加受伤风险，职业医生可以帮助工人找到补救措施。
