Study on influencing factors of work-related musculoskeletal disorders in neck and lower back among shipbuilding workers
Objective To investigate the related influencing factors of work-related musculoskeletal disorders(WMSDs)in neck and lower back among shipbuilding workers.Methods From March to December 2023,a convenience sampling method was used to select 2 032 shipbuilding workers from Guangdong Province and Liaoning Province as the survey subjects.The"Musculoskeletal Disorders Questionnaire"was used to investigate the prevalence of WMSDs in their neck and lower back,and the data were analyzed.Results The prevalence of neck and lower back WMSDs among 2 032 shipbuilding worker were 21.5％and 16.9％,respectively.Workers who frequently worked for colleagues,often/frequently worked in uncomfortable postures and poor neck postures had a higher risk of developing neck WMSDs compared to those who did not frequently work for colleagues,rarely/sometimes worked in uncomfortable postures and poor neck postures(all P＜0.05).The risk of lower back WMSDs was higher in workers with a length of service more than 10 years compared with workers with less than 5 years of service,and the longer the work experience,the higher the risk of developing lower back WMSDs(P＜0.05).Workers with abnormal body mass index(BMI)index,lack of physical exercise,frequent overtime,need for upper limb or hand exertion,frequent/frequent use of uncomfortable postures,and poor working posture in the lower back had a higher risk of developing lower back WMSDs(all P＜0.05).Conclusion The neck and lower back WMSDs of shipbuilding workers may be influenced by occupational factors and individual factors.Improving poor ergonomic posture,reasonable scheduling and appropriate physical exercise can reduce the risk of WMSDs.
