Prevalence of computer vision syndrome among medical students at Pham Ngoc Thach University of Medicine
Tóm tắt
Introduction: Computer Vision Syndrome (CVS) is considered an abnormality of the visual system that occurs when using electronic devices for a long time. With the explosive development of digital technology, CVS has become a syndrome of concern. This survey evaluated the prevalence of CVS in general medical students at Pham Ngoc Thach University of Medicine. At the same time, learn about the differences in the prevalence of CVS between courses, and identify common symptoms and factors related to CVS.
Method: A cross-sectional study using the convenience sampling method was conducted. Students were asked to fill out an electronic self-administered survey. The survey collected information on demographics, electronic device usage habits, and symptoms of CVS using the validated CVS–Q questionnaire. In addition, the Chi-square test, Fisher’s Exact, and logistic regression were also used to evaluate associations between CVS and other factors.
Result: Among the total of 344 samples, there were 174 females (50.58%) and 170 males (49.42%). Of these, 84.59% suffered from CVS, with dry eye being the most common symptom (15.7%), followed by itching (15.4%), and feeling eyesight is worsening (15.4%). The least common symptom was double vision (3.2%). The prevalence of CVS from the first to the sixth year was 85.8%; 86.9%; 84.8%; 86.8%; 82.2%; and 78.2%. A significant positive correlation was observed between CVS with time spent using the devices (OR = 0.336; 95%CI: 0.143 – 0.789), gender (OR = 2.00; 95%CI: 1.112 – 3.741), taking breaks while using the device (OR = 2.00; 95%CI: 1.078 - 3.535), adjusting brightness, contrast (OR = 2.00; 95%CI: 1.031 – 4.062) and distance from eye to devices (OR = 3.548; 95%CI: 1.285 – 9.797).
Conclusion: CVS is common among medical students; significant risk factors should be addressed to reduce the symptoms and improve work productivity. It is a necessity to raise awareness among medical students regarding computer- related health problems.
