By means of self-registered questionnaires on Visual display terminal (VDT) work, environment and working postures, visual and musculoskeletal subjective symptoms were surveyed in a university and its affiliated schools. We carried out multiple logistic regression analysis on fatigue of the eyes, shoulder stiffness and lower back pain. Persons surveyed were office workers, university teachers and high school teachers engaged in VDT work, including 321 men and 154 women. As regards the covariates on analysis, 11 terms relevant to VDT work, work environment and working postures were selected by considering multicollinearity among the items in our original interview sheet. Only the working with humped shoulders presented significant odds ratio increases on fatigue of the eyes and shoulder stiffness in both men and women. In addition, changeover of the personal computer (PC) type from a desktop PC to a laptop PC was found to have significant trends for subjective symptom improvement.
