Abstract: Objective To investigate the effects of occupational stress on work-related musculoskeletal disorders(WMSDs) among medical staff in Hainan Province. Methods From June to December 2023,a multistage stratified cluster random sampling method was used to investigate occupational stress and factors related to WMSDs among 1 663 medical staff engaged in diagnosis,treatment,and nursing care in 23 medical institutions in Hainan Province,and the data were analyzed. Results The detection rate of occupational stress among medical staff was 30.6%,and the prevalence of WMSDs in the past 1 year was 81.7%. The prevalence of WMSDs in all parts of the body was 64.5% in the neck,60.2% in the shoulder,and 59.2% in the back in descending order,and the prevalence of WMSDs in all parts of the body in the occupational stress group was higher than that of the non-occupational stress group(all P<0.01). The prevalence of multi-site WMSDs was 31.9% for ≥6 sites,11.7% for 1 site,and 10.5% for 4 sites in descending order,and the prevalence rates of WMSDs and ≥6-site WMSDs in the occupational stress group were higher than those in the non-occupational stress group(all P<0.01). The prevalence of WMSDs was higher in the occupational stress group with an OR of 1.448(95% CI：1.079-1.944) after excluding the effects of confounding factors,such as age and average monthly income,using the non-occupational stress group as a reference. Conclusion The prevalence of WMSDs among medical personnel in Hainan Province is high,and the favorable sites are mainly in the neck,shoulder,and back,and occupational stress can increase the risk of WMSDs among medical personnel,and future interventions can be carried out in terms of alleviating the occupational stress of medical personnel and decreasing the time of working in a poor posture in order to prevent the occurrence of WMSDs and improve the health of medical personnel.
