Study objectives : The purpose of this study was to evaluate the effect of sleep deprivation on daytime sleepiness, fatigue, and attention measured by Vienna Test System and VAS. Participants : 9 healthy, normal young male college students participated in this study. Participating subjects were in good physical and psychological health and were asymtomatic as to sleep/wake complaints. Intervention : Subjects visited our laboratory by 08 : 00 at the first day, and they had baseline Vienna Test(at 9 : 00, 11 : 00, 14 : 00, and 16: 00). Each time, the subjects completed VAS for sleepiness and fatigue before they underwent an Vienna Test to evaluate their attention and vigilance. They had 4 hours of sleep at 1st day, 2 hours at 2nd days, and total sleep deprivation at 3rd day and repeated the same process as those of the first day. Result : As compared to baseline, subjects had significantly increased daytime sleepiness and fatigue and decreased vigilance, but no significant difference in attention. The more sleep deprivation duration increased, the more daytime sleepiness and fatigue increased. Conclusion : Additional study is needed to get objective data for daytime sleepiness and fatigue and to correlate among daytime sleepiness, fatigue, attention and vigilance.
