This study examined subjective symptoms attacking the musculoskeletal system of insurance inspectors from April 8th to April 30th, 2002, and calculated its attack rate. NIOSH’s standardized questionnaire was applied in order to uncover correlative factors, and a structuralized self-administered questionnaire was used to measure general characteristics, duty-related factors, and satisfaction degree on VDT worktable. Two hundred one questionnaires were collected and analyzed into the following outcomes.
1. Subjective symptom rates of musculoskeletal disorder are 74.6% at the shoulder, 62.7% at the neck, 52.7% at the waist, 47.3% at the hand/wrist/fingers, and 36.3% at the arms.
2. Bivariate analysis was conducted on the factors related with subjective symptoms on the musculoskeletal system against the observed factors, and significant relations were found as follows: marital status in general characteristics vs the hand/wrist/fingers; in duty-related factors, the number of working hours per day vs the hand/wrist/fingers, VDT continuous working hours, working speed adjustment vs the neck, and the degree of job-satisfaction vs the waist; in satisfaction degrees of VDT worktable, the height of chairs vs the hand/wrist/fingers, the height of worktable vs the arms, the hand/wrist/fingers, and the waist, the working space on the table vs the neck, and the waist, the space under the worktable vs the waist, the hands’ posture on the keyboard vs the neck, the hand/wrist/fingers, and the waist.
3. Correlation analysis was conducted on musculoskeletal disorder symptoms and related-factors: a single person, the long length of working hours per day vs the hand/wrist/fingers, long length of VDT working hours vs the neck, in a state of rest, and in working speed adjustment vs the neck, in the case of being dissatisfied with work vs the waist, and in the case of being dissatisfied with the VDT worktable vs the neck, the arms, and the hand/wrist/fingers showed statistically significant differences.
4. Logistic regression analysis was conducted to uncover correlative factors with the musculoskeletal disorder symptoms; the working hours per day, and the height of chair significantly affected the neck; the working hours per day affected the shoulders; the height of table affected the arms; the degree of job-satisfaction, VDT continuous working hours, and the space under the worktable affected the waist.
As shown above, insurance inspectors should consider working hours per day, VDT continuous working hours, and resting time, in order to prevent musculoskeletal disorder symptoms rate by body parts, and ergomechanic and biomechanical conditions related with chairs and tables should also be considered in order to prevent musculoskeletal disorder symptoms.
