Abstract:
Objective:To investigate the occurrence of work-related musculoskeletal disorders (WMSDs) in the cabinet factory workers, and explore the influencing factors of workers' WMSDs.Methods:A cross-sectional survey method was used to investigate the risk factors such as basic conditions, labox dnganiza, ergonomics load and occurrence of WMSDs of 821 workers in a cabinet factory of a furniture manufacturing company in Guangdong Province using the electronic version of the Musculoskeletal Injury Questionnaire from October to December 2019. χ 2 test and logistic regression were used to analyze the risk factors leading to WMSDs. Results:The incidence of WMSDs in cabinet production workers reached 51.5% (423/821) , and the top three incidences were shoulder (28.4%, 233/821) , neck (28.1%, 231/821) , and wrist (25.9%, 213/821) . The incidence of neck WMSDs was statistically significant among different types of work ( P<0.05) . Multiple repetitive operations per minute ( OR=1.70) , torso often maintaining the same posture ( OR=1.61) , turning heads for a long time ( OR=1.58) and frequent heavy lifting ( OR=1.44) were risk factors for the occurrence of shoulder WMSDs ( P<0.05) . Frequent maintenance of the same posture in the neck ( OR=1.91) , repeated operations per minute ( OR=1.87) , shortage of department staff ( OR=1.65) and turning head for a long time ( OR=1.48) were risk factors for the occurrence of neck WMSDs ( P<0.05) . Long-term bending of the wrist ( OR=2.25) , grasping objects tightly ( OR=2.13) , working hard on the upper limbs or hands ( OR=1.91) , shortage of department personnel ( OR=1.84) , repeated operations per minute ( OR=1.68) and the use of vibration tools ( OR=1.51) were risk factors for the occurrence of WMSDs in the wrist ( P<0.05) . Conclusion:The incidence of WMSDs in cabinet factory is relatively high, the occurrence of WMSDs in the shoulders, necks and wrists is more serious. Reasonable labor organization and reducing the load of poor ergonomics in the workplace, can reduce the occurrence of WMSDs in production workers.
