Analysis of the association of musculoskeletal disorder,sleep quality and occupational stress among medical staffs in a hospital / 中国职业医学

ABSTRACT

OBJECTIVE: To study the current status of musculoskeletal disorders( MSDS) among medical staffs,and to analyze the relationship of MSDS,sleep quality and occupational stress. METHODS: Four hundred and fourteen medical staffs from a tertiary hospital were selected as research subjects by using judgment sampling method. The questionnaires of Nordic Musculoskeletal Questionnaire,Pittsburgh Sleep Quality Index and Core Questionnaire of Occupational Stress were answered and analyzed. RESULTS: The annual prevalence and week prevalence of MSDS were 67. 9%( 281/414) and 58. 5%( 242/414) in the study group. The neck,waist and shoulder were areas of high incidence of MSDS in the medical staffs,and the annual prevalence was 67. 9%,67. 6% and 54. 6%,while the week prevalence was 56. 5%,58. 5% and 47. 8% respectively. There were 58. 9%( 244/414) medical staffs who had sleep problems. The MSDS annual prevalence,week prevalence of neck and shoulder for poor sleep quality in medical staffs were higher than that of good sleep quality group( P < 0. 05). There were 30. 2%( 125/414) medical staffs who had occupation stress. The annual prevalence,week prevalence of neck and shoulder MSDS in the occupation stress group of medical staffs were higher than the non-occupation stress group( P < 0. 05). Multivariate logistic regression analysis showed that length of service,sleep duration,sleep quality and work requirements were the risk factors of MSDS( P < 0. 05). CONCLUSION: The incidence of MSDS is higher in medical staffs with poor sleep quality and high occupational stress.
