Abstract:
OBJECTIVE: To analyze the prevalence and influencing factors of work-related musculoskeletal disorders(WMSDs) in civil aviation flight attendants. METHODS: A total of 810 flight attendants from three civil aviation airlines in China were selected as research subjects using the convenient sampling method. The revised Musculoskeletal Disorders Investigating Questionnaire was used to investigate the prevalence of WMSDs in various parts of the body in the past year. RESULTS: The total prevalence of WMSDs in flight attendants in this survey was 64.4%(522/810). The prevalence of WMSDs in various parts of the body from high to low was: neck(48.0%), shoulder(38.6%), lower back/waist(26.0%), upper back(19.8%), feet(15.1%), knee(14.0%), hip and leg(11.0%), hand and wrist(9.0%) and elbow(5.1%). The results of multivariate logistic regression analysis showed that working with an uncomfortable posture and the shortage of staff in the work sector were risk factors for neck WMSDs(all P<0.05). The protective factors were sufficient rest time and voluntary decision when to take a break during work(all P<0.05). Carrying heavy objects >20 kg, working in uncomfortable posture and shortage of staff were risk factors for shoulder WMSDs(all P<0.05). Working in uncomfortable posture and repeated an operation every minute were risk factors for lower back/waist WMSDs(all P<0.05), and sufficient rest time was its protective factor(P<0.05). CONCLUSION: The prevalence of WMSDs in civil aviation flight attendants is high, and the neck, shoulder and ower back/waist are the most commonly affected part of the body. The main influencing factors are poor ergonomics and work organization.
