Abstract: Objective To analyze the incidence and influencing factors of musculoskeletal disorders in medical staff， and provide a basis for formulating intervention measures.Methods A questionnaire survey on the prevalence and related factors of musculoskeletal disorders was conducted with the medical staff in a hospital in Changsha who worked in the unit for more than 1 year. Descriptive epidemiological analysis method was used to analyze， and univariate and multivariate analysis methods were used to analyze the influencing factors of musculoskeletal disorders among medical staff.Results A total of 802 medical staff in the hospital were investigated. The sex ratio between men and women was 0.8∶1， and the age was 18 to 65 years old. The population was mainly 18 to 29 years old， accounting for 56.61%， and the nursing department accounted for 58.10%. Among the 802 medical staff， 260 （32.42%） suffered from musculoskeletal disorders， and 202 cases （77.69%） were able to relieve themselves. Multivariate analysis showed that the medical staff who was female （OR＝1.376）， working in nursing and medical assistance departments （OR＝3.216， 3.149）， had older age （OR＝3.435）， longer working years （OR＝2.759）， anxiety symptoms （OR＝3.177）， cramped workspace （OR＝2.563）， moving heavy objects≥5 times per day （OR＝3.501） had a higher risk of musculoskeletal disorders； exercise 1-3 times and ≥4 times per week （OR＝0.358， 0.150） had a lower risk of musculoskeletal disorders.Conclusion The incidence of musculoskeletal disorders in medical staff is relatively high， and there are many influencing factors. The relevant medical departments should take corresponding intervention measures for the medical staff to reduce the risk of musculoskeletal disorders.
