Abstract:

Objective To explore the occurrence and influencing factors of work-related musculoskeletal disorders(WMSDs) among workers in electronic manufacturing enterprises in China by using the Meta-analysis method,and provide a reference for the prevention and treatment of WMSDs in this population. Methods Literature on the occurrence of WMSDs among workers in electronic manufacturing enterprises in China was retrieved from databases such as China National Knowledge Infrastructure (CNKI),Wanfang Data,Chinese Science and Technology Journal Database(VIP),Pubmed,Web of Science,and Cochrane Library. The retrieval period was from the establishment of the databases to May 2025. After screening the relevant literature according to the inclusion and exclusion criteria,the data of the included literature was extracted and analyzed using Stata 12.0 software. Results A total of 20 literatures were included. The Results of the Meta-analysis showed that the prevalence of WMSDs among workers in electronic manufacturing enterprises in China was 44.6%(95%CI:40.7%-48.6%). The prevalence of single-site WMSDs was 12.3%(95%CI:9.8%-14.8%),and the prevalence of multi-site WMSDs was 34.5%(95%CI:22.0%-47.1%). The top three prevalence rates of WMSDs in each part of the body were as follows:neck 29.8%,shoulders 25.2%,and hands/wrists 17.8%. Long working years(OR=1.79,95%CI:1.20-2.65),long sitting hours(OR=1.31,95%CI:1.18-1.46),maintaining the same posture for a long time(OR=1.96,95%CI:1.41-2.73),prolonged repetitive actions(OR=1.80,95%CI:1.44-2.25),sufficient rest time (OR=0.58,95%CI:0.47-0.70),taking turns to complete work(OR=0.70,95%CI:0.50-0.98) were the influencing factors for the occurrence of WMSDs. Conclusion The incidence of WMSDs among workers in electronic manufacturing enterprises in China is relatively high,and multi-site WMSDs is more common than single-site WMSDs. Long working years,long-term sitting work,maintaining the same posture for a long time,and long-term repetitive actions are risk factors for the occurrence of WMSDs,while sufficient rest time and taking turns to complete work are protective factors for the occurrence of WMSDS.
