Analysis of the correlation between work-related musculoskeletal disorders and occupational stress in electronic manufacturing workers
Objective To explore the effect of occupational stress on work-related musculoskeletal disorders(WMSDs)in electronics manufacturing workers.Methods A total of 392 front-line workers in two electronic manufacturing enterprises in Guangdong Province were selected as the research subjects using the judgment sampling method.The prevalence of WMSDs and the level of occupational stress of the research subjects were investigated using the Musculoskeletal Disorders Questionnaire and the Core Occupational Stress Scale.Results The total WMSDs detection rate was 39.5％,and the multi-site WMSDs detection rate was 30.6％.The detection rate of occupational stress was 14.8％.The total WMSDs detection rate and multi-site WMSDs detection rate in the occupational stress group were higher than those in the non-occupational stress group(65.5％vs 35.0％,56.9％vs 26.0％,both P＜0.01).Binary logistic regression analysis result showed that the risk of WMSDs in the occupational stress group was higher than that in the non-occupational stress group after adjusting the effect of confounding factors such as age,gender,job type and work days per week(P＜0.01).Conclusion The occupational stress may increase the risk of WMSDs in electronics manufacturing workers.Reducing the level of occupational stress among workers in electronic manufacturing enterprises is beneficial for reducing the risk of WMSDs.
