Influencing factors of neck musculoskeletal disorders in an airport handlers / 中国职业医学

ABSTRACT

OBJECTIVE: To explore the influencing factors of neck work-related musculoskeletal disorders( WMSDs) and their effects in airport porters. METHODS: A total of 413 airport porters were chosen as study subjects using judgment sampling method. Chinese version of Musculoskeletal Questionnaire was used to investigate the prevalence of WMSDs.Then structural equation model was constructed and used to analyze the influencing factors of neck WMSDs. RESULTS: The prevalence of neck WMSDs in airport porters was 37. 3%( 154/413). Postural load,mental workload and length of service had a direct effect on neck WMSDs of porters( path coefficients were 0. 405,0. 166,0. 296,P < 0. 05),and mental workload also had an indirect effect on neck WMSDs through postural load( path coefficient was 0. 103,P < 0. 01).CONCLUSION: Posture load,mental workload and length of service are risk factors of neck WMSDs in airport porters.
