Prevalence and Psychosocial Risk Factors of Upper Extremity Musculoskeletal Pain in Industries of Taiwan: A Nationwide Study: Hsin‐Yi Lee, et al. Institute of Occupational Medicine and Industrial Hygiene, College of Public Health, National Taiwan University, Taiwan—Prevalence of upper extremity disorders and their associations with psychosocial factors in the workplace have received more attention recently. A national survey of cross‐sectional design was performed to determine the prevalence rates of upper extremity disorders among different industries. Trained interviewers administered questionnaires to 17,669 workers and data on musculoskeletal complaints were obtained along with information on risk factors. Overall the 1‐year prevalence of neck (14.8%), shoulder (16.6%), and hand (12.4%) disorders were higher than those of the upper back (7.1%) and elbow (8.3%) among those who sought medical treatment due to the complaint. Workers in construction and agriculture‐related industries showed a higher prevalence of upper extremity disorders. After multiple logistic regression adjusted for age, education, and employment duration, we found job content, physical working condition, a harmonious interpersonal relationship at the workplace and organizational problems were significant determinants of upper extremity disorders in manufacturing and service industries. Male workers in manufacturing industries showed more concern about physical working conditions while female workers in public administration emphasized problems of job content and interpersonal relationships. We concluded that these factors were major job stressors contributing to musculoskeletal pain of the upper extremity.
