Abstract:
Objective The prevalence and risk factors of occupational musculoskeletal diseases among office clerks was analyzed, in order to provide theoretical basis for health intervention.
Methods Totally 10 enterprises in Shenzhen city were selected in convenient sampling way and 514 office clerks in these enterprises were studied. The self-designed questionnaire, comprehensively based on the Nordic countries and musculoskeletal disease questionnaire(NMQ), the Netherlands and musculoskeletal disease questionnaire (DMQ), and musculoskeletal disorders questionnaire in China, were used to survey the prevalence and risk factors of management of occupational musculoskeletal disorders among these office clerks. The logistic regression analysis was used to analyze the risk factors of occupational musculoskeletal disorders in three body parts(neck, shoulder and waist)with high incidence.
Results The annual prevalence of occupational musculoskeletal disorders among office clerks was 54.12%, with the prevalence in each part as neck (39.4%), shoulder (36.2%), waist (30.9%), back (18.6%), knee(11.5%), wrist (10.1%), hip(8.1%), ankle(7.7%) and elbow(4.4%). The logistic regression analysis results showed that the neck in the natural position was a protective factor of neck musculoskeletal disorder(OR = 0.893 8, P < 0.05);females had a higher prevalence of the shoulder musculoskeletal disorder than males (OR = 1.162 7, P < 0.05);frequent change of sitting position was a protective factor for lumbar musculoskeletal disorder(OR = 0.890 3, P < 0.01).
Conclusion The prevalence of occupational musculoskeletal disorders among office clerks in enterprises was high, specifically in the neck, shoulder and waist. Maintaining a variety of unhealthy postures during desk work will increase the body burden of musculoskeletal joints of the body and cause musculoskeletal injury. Appropriate interventions should be taken to reduce occupational musculoskeletal disorders among office clerks.
