In addition to serious occupational injuries, construction workers experience many occupation-related musculoskeletal disorders (MSDs) such as lower-back pain. This study is aimed to explore the relationship between MSDs and job risk factors of construction workers. The data were collected through a nationwide questionnaire - “Survey of Employees’ Perceptions of Safety and Health in the Work Environment in 1998 Taiwan” and analyzed by logical regression model. The results show that one-year prevalence rate of MSDs is 65.8%, which is higher than that of other industries, so does the rate of MSDs with clinical treatment (severe MSDs), 37.7%. Shoulder disorder (36%) and lower-back disorder (34%) are the most common MSDs, and severe lower-back disorder (18%) is the most frequent severe MSDs. Whole body vibration, forceful handling, vibrating hand tools, age, awkward postures, and years on the job are the statistically significant factors for severe lower-back disorder. The significant risk factors for the lower extremities are forceful handling, whole body vibration, awkward postures, and age. Except age, to prevent MSDs the workers must reduce the forceful handling activities and awkward postures. The construction workers are also concerned with heavy hand tool problems, but it is not a significant risk factor for MSDs. |
