The use of Video Display Terminals (VDTs) has increased dramatically in the past 10 years and is projected to increase. Particular concerns related to the use of VDTs include vision, dermatological, reproduction, stress and ergonomics has been directed. To evaluate the association between VDT use and the adverse conditions related to vision, musculoskeletal conditions, skin, female reproductive conditions and psychological conditions, we conducted this cross-sectional study. The study group consisted of clerical workers exposed to VDTs in Port Said, fsmai-lia and Suez cities for at least 12 hours weekly for at least one year. A control group selected from the same worksite with the same work-force characteristics but not exposed to VDTs. The two groups were matched with each other as regards sex and age. The sample size turned to be 150 workers per a group. A questionnaire was used for the collection of personal and occupational data as well as health events of various body systems. Taylor and Zung self-rating scales were used for measuring anxiety and depression, respectively among our population. Screen characteristics were also asked for blood pressure and visual acuity were measured for each person included in the study. The results of this study indicated an increased prevalence of adverse conditions pertaining to musculoskeletal discomfort, menstrual disorders, visual disorders, dermato-logical disorders and anxiety (using Taylor self-rating scale) among clerical workers who used VDTs.
