Objectives : The purpose of this study was to investigate the state of computer use, VDT related symptoms and its related factors in adolescents.
Methods : A questionnaire survey was performed for 921 students in 4 (1 boys and 1 girls middle and high school) schools in a city from April 23 to April 28, 2001. The students who had musculoskeletal symptoms due to previous injury or disease and who submitted incomplete Questionnaire were excluded. The final study subjects were 826 students. Degree of VDT related symptoms was measured with Likert 5 (0 to 4) scales.
Results : Average score of subjective symptom for VDT syndrome was 1.08 for musculoskeletal symptoms, 0.89 for eye-related symptoms, 0.80 for psychosomatic symptoms, 0.78 for psychological symptoms, and 0.54 for skin-related symptoms. In multiple regression analysis, eye-related symptom score was related with the duration of computer use at one time (p ≶ 0.05) and illumination (p ≶ 0.01). Psychologic symptom score was related with sex (p ≶ 0.01). degree of noise (p ≶ 0.01), and distance between monitor and eyes (p ≶ 0.05). Psycosomatic symptom score was related with duration of computer use at one time (p ≶ 0.05), experience of staying up all night (p ≶ 0.05), and degree of noise (p ≶ 0.01). Musculoskeletal symptom score was significantly higher in high school than in middle school students (p ≶ 0.05), and it was related with duration of computer use at one time (p ≶ 0.05), experience of staying up all night (p ≶ O.O1), illumination(p ≶ 0.05), height of desks and chairs(p ≶ O.O1), and distance between monitor and eyes(p ≶ 0.05). Skin-related symptom score was related with experience of staying up all night (p ≶ O.O1), computer use after lOpm at night (p ≶ 0.05), and degree of noise (p ≶ O.O1).
Conclusions : These findings suggest that a systematic health education for proper use of computer is necessary for prevention of VDT syndrome in adolescents.
