Abstract Objective To investigate the prevalence and influencing factors of work-related musculoskeletal disorders (WMSDs) in neck and shoulder among workers in pharmaceutical and chemical enterprises, so as to provide the basis for prevention of WMSDs. Methods Workers in 8 pharmaceutical and chemical enterprises in Jinhua City, Zhejiang Province from July to October 2023 were sampled using a stratified random sampling method, and demography, work conditions and WMSDs prevalence were collected using questionnaire surveys. Factors affecting WMSDs in neck and shoulder were analyzed using a multivariable logistic regression model. Results A total of 1 343 workers were surveyed, including 496 males (36.93%) and 847 females (63.07%). The mean age of workers was 38 (15) years, and the length of service in current posts was 6 (8) years. There were 356 workers with WMSDs (26.51%), with 206 workers with neck WMSDs (15.34%) and 167 workers with shoulder WMSDs (12.43%). Multivariable logistic regression analysis showed that gender (female, OR=1.692, 95%CI: 1.203-2.381), sufficient rest time (OR=0.660, 95%CI: 0.471-0.926) and maintaining same neck posture for a long time (OR=1.690, 95%CI: 1.148-2.510) were factors affecting neck WMSDs; gender (female, OR=1.572, 95%CI: 1.060-2.311), sufficient rest time (OR=0.619, 95%CI: 0.422-0.906), repetitive daily work (OR=1.678, 95%CI: 1.064-2.647), uncomfortable work posture (OR=3.791, 95%CI: 1.330-10.803), multiple repetitive movements per minute (OR: 1.988-2.413, 95%CI: 1.060-4.161) and maintaining same neck posture for a long time (OR=1.926, 95%CI: 1.218-3.043) were factors affecting shoulder WMSDs. Conclusion The prevalence of WMSDs in neck and shoulder are high among workers in pharmaceutical and chemical enterprises in Jinhua City, and mainly affected by gender, rest time and adverse ergonomics.
