Risk Factors For Visual Display Terminal Syndrome Among School-Age Children During Coronavirus Disease 2019 Home Quarantine Period
Abstract
Background: This study aimed to determine the current status and risk factors for visual display terminal syndr ome (VDTS) among school-age children during the coronavirus disease 2019 (COVID-19) home quarantine period.
Material and Methods: Using a stratifi ed cluster sampling method, data on basic information, history of eye disease, visua l display terminal (VDT)-related questions, lifestyle status, and Convergence Insuffi ciency Symptom Survey (CISS) scores of 720 school-age children who participated in home-based learning during the COVID-19 lockdown in Shanghai, China, from April to May 2022, were collected via an online questionnaire. Multivariate logistic regression analysis was performed to determine factors associated with VDTS.
Results: Participants were divided into VDTS positive (VDTS+; age, 9.78 ± 2.23 years) and negative (VDTS-; age, 9.46 ± 1.70 years) groups based on their CISS scores. Diff erences in the history of eye diseases between the two groups were statistically signifi cant. The duration of VDT use and type diff ered signifi cantly between the two groups. Daily out door activity time of the VDTS+ group was signifi cantly shorter than that of the VDTS- group, but the diff erence in sleep duration between the two groups was not statistically signifi cant. Refractive error, outdoor activity time, duration of VDT use, and VDT type were correlated with VDTS.
Conclusion: Upper-grade school-age children are more prone to developing symptoms of VDTS. Refractive error, outdoor activity time, duration of VDT use, and VDT type are signifi cant infl uencing factors for the development of VDTS, which necessitates adopting measures to protect the eyes by targeting these aspects.
