[The prevalence and influencing factors of work-related musculoskeletal disorders of oilfield workover workers].

Objective: To investigate work-related musculoskeletal disorders (WMSDs) of workover workers in an oilfield and explore the influencing factors. Methods: In June 2016, 685 workover workers were selected as working group, and 191 other workers exposed to toxic and harmful operations were selected as control group. Cross sectional investigation was conducted by self-made questionnaire, and the influencing factors of musculoskeletal disorders were analyzed by unconditional multivariate Logistic regression. Results: The total annual prevalence of WMSDs for workover workers was 90.5%, with the highest prevalence of low back pain of 71.5%. The prevalence of WMSDs increased with the increase of service age, and the difference between the drinkers was higher than that of the non drinkers (P<0.05) . Multivariate Logistic regression analysis showed that working age, drinking and the posture of lifting heavy objects were risk factors for WMSDs in workover workers. Conclusion: The WMSDs appears to be a serious problem in oilfield workover workers. Corresponding measures should be taken to prevent the risk factors and control the occurrence of diseases effectively.目的： 调查某油田修井作业工人工作相关肌肉骨骼疾患（WMSDs）情况，探讨其影响因素。 方法： 于2016年6月，选取685名修井作业工人为作业工组，接触有毒有害作业的其他工种191人作为对照组。采用自制调查表进行横断面调查，并采用非条件多元logistic回归分析，肌肉骨骼疾患的影响因素。 结果： 修井作业工的WMSDs总的年患病率为90.5%，其中腰背痛患病率最高71.5%。WMSDs患病率随工龄增加而增加，饮酒者高于不饮酒者，差异均具有统计学意义（P<0.05）。多元Logistic回归分析结果显示，工龄、饮酒、搬抬重物姿势为修井作业工人WMSDs发生的危险因素。 结论： 修井作业工人WMSDs较严重，企业应针对危险因素采取相应措施，有效预防控制疾病发生。.
