چکیده

in the early 1980s and the rapid development of science and technology, computers have been applied in various industries. The China National Bureau of Statistics reported that 63.8% of workplaces used computers in 2007, and the percentage reached 88.1% in the finance and business services sector. Working in an office environment is widely known to be associated with work-related musculoskeletal disorders (WMSDs), which are a diverse set of conditions characterized by pain, aching, stiffness, fatigue, discomfort, tingling and/or numbness, generally appearing in the fingers, hand, wrist, elbow, arm, shoulder, neck and/or low back. The literature consistently demonstrates that VDT users are at increased risk for neck and/or shoulder symptoms relative to the risk expected in low-exposure office or industrial tasks . WMSDs in the neck (WMSDs-N) are the most common work-related upper extremity disorders (WRUEDs), and a large range of individual, physical and psychosocial risk factors are associated with the development of WMSDs-N. Individual factors include age, gender, education level, smoking habits and so on; work-related physical factors include awkward posture during work, bending, static sedentary posture and task demands; work-related psychosocial factors include overtime and time spent working to meet deadlines. In addition, several studies have shown that ergonomic factors (e.g., work station design) were possibly linked to WRUEDs. Although WRUEDs among VDT workers have been a topic in occupational health research for many years and there have been a large number of epidemiological studies on WMSDs, there is still little understanding of the prevalence of WMSDs in different countries. Also, the etiology of WMSDs in computer work is still not completely understood. It is not clear whether the causes of WMSDs are similar in differAbstract: Visual Display Terminal Use Increases the Prevalence and Risk of Work-related Musculoskeletal Disorders among Chinese Office Workers: A Cross-sectional Study: Shanshan WU, et al. Department of Occupational and Environmental Health, School of Public Health, Peking University, P.R. China—Objectives: Little is known about workrelated musculoskeletal disorders (WMSDs) among computer users mainland China. The aim of this study was to estimate the prevalence of WMSDs in office workers in Beijing, and to determine risk factors for WMSDs in the neck (WMSDs-N). Methods: In a crosssectional study, a self-administered questionnaire was delivered to 720 office workers who use a computer as a main working tool. Odds ratios (ORs) were calculated for risk factors. Results: The prevalence of WMSDs of the neck, shoulder, wrist/hand, upper back and low back amongst office workers were 55.5, 50.7, 31.5, 26.2 and 6.6%, respectively. Both individual risk factor and working condition factors were found to be independently related to WMSDs-N. Conclusions: The WMSDs prevalence rates among office workers in Beijing, China, were high. The most affected area was the neck. Preventive measures for office work should be focused on the neck (e.g., rest breaks). (J Occup Health 2012; 54: 34–43)
