Purpose: The purpose of this study was to investigate the effect of the increased usage time of video terminals, including smartphones, on eye and mental health among university students in the situation of COVID-19.
Methods: The subjects of 124 university students who responded to the online survey for two months from March 2021 were analyzed. The questionnaire included general characteristics, usage time of video terminals, ocular symptoms with 12 items related to VDT syndrome and the Korean version of the depression screening tool (PHQ-9). Eye symptoms were evaluated from 0 to 4 points in each item, and depression was evaluated on a 4-point scale to calculate a total score. According to the increased usage time of the video terminal after COVID-19, it was classified into group 1 (no change), group 2 (1 to 2 hours), group 3 (3 to 4 hours), and group 4 (5 hours or more).
Results: The average daily use of video terminals was 8.05±2.99 hours, showing an increase of more than 5 hours per day in 19.4% of subjects after COVID-19. In eye symptoms, ‘the eye fatigue’ and ‘worsening of eyesight’ showed high scores of 1.84 points and 1.24 points, respectively. The total score for PHQ-9, which is a measure of mental health, was 4.78±4.62 points, with 29.8% for mild, 7.8% for moderate depression, and 5.6% for moderately severe depression. In the group with increased use of video terminals for more than 5 hours per day, the total score of eye symptoms and depression was higher than that of the group less than 4 hours, and there was a statistically significant relationship between the level of eye and depression.
Conclusions: In the development of IT technology and the pandemic of COVID-19 situation, the use of video terminals by university students has increased sharply, and symptoms of eye and mental health have been felt according to the increased usage time. Through the results of this study, it was found that preventive activities for physical and mental health management are urgently needed.
