Objective To evaluate the exposure risk level of work-related musculoskeletal disorders (WMSDs) among automobile assembly workers and explore its relationship with occurrence.
Methods British Quick Exposure Check (QEC) and Nordic Musculoskeletal Questionnaire (NMQ) were used to conduct an epidemiology survey on general condition, level of exposure risk, WMSDs occurrence and others among 1 465 assembly workers in an automobile factory in north China.
Results The exposure levels of WMSDs at the body parts of neck, back, shoulder/arm, and hand/wrist of most workers were high or very high, and there were differences of exposure levels between the workers in different sections. The incidence of WMSDs at the four parts of neck, back, shoulder/arm, and hand/wrist ranged from 4.98% to 9.69%, and increased with the increasing level of exposure risk.
Conclusion WMSDs exposure risk exists in the automobile assembly workers and varies with body part and working section. An exposure-response relationship is observed at the four parts of neck, back, shoulder/arm, and hand/wrist.
