Abstract:
{L-End}Objective To investigate the prevalence and influencing factors of work-related musculoskeletal disorders (WMSDs) of live-electric line workers in the power supply enterprises. {L-End}Methods A total of 1 479 live-electric frontline workers in the power supply bureaus under China Southern Power Grid Co., LTD in Guangxi Zhuang Autonomous Region, Guangdong Province and Yunnan Province were selected as the research subjects using the cluster sampling method. The revised Chinese version of the Musculoskeletal Disorders Questionnaire was used to investigate the prevalence of WMSDs and their influencing factors in the past year. {L-End}Results The prevalence of WMSDs was 61.4%. The prevalence of WMSDs in nine body sites ranged from 11.3% to 45.1%, with the highest prevalence being on three sites of neck, shoulder and lower back with a prevalence of 45.1%, 36.0% and 30.8%, respectively. The results of multivariate logistic regression analysis showed that the influencing factors of WMSDs in the neck, shoulder, and lower back were different, but all related to individual factors, poor ergonomics factors, and unreasonable work organization factors. The influencing factors simultaneously affecting these three sites included length of service, educational level, working in a sitting posture for a long time, working in uncomfortable postures, adequate rest time, starting to work after rest, deciding when to start and finish by oneself, and shortage of staff in the department or group. The factors affecting both neck and shoulder WMSDs were gender and back bending slightly for a long time. The factors affecting both neck and lower back were age and back bending significantly for a long time. {L-End}Conclusion The prevalence of WMSDs in the live-electric line workers in power supply enterprises is high, mainly occurring in the neck, shoulders, and lower back. The influencing factors are individual factors, poor ergonomics factors, and unreasonable work organization.
