Abstract:
Objective:The current situation and associated factors of primary and middle school students screen time and related eye hygiene in different periods before and after COVID-19 were investigated, so as to provide a scientific basis for taking targeted measures of preventing and controlling myopia among those students.
Methods:A total of 11 402 students were selected from 24 primary schools, 18 junior high schools and 16 high schools by multi stage stratified cluster sampling method. And a questionnaire survey was conducted among students and their parents to understand students screen time and screen hygiene behaviors and related factors in different periods before and after the outbreak of COVID-19.
Results:The rate of screen overuse was 7.26%, 9.12% and 35.30% during school days, weekends and home study, respectively. The overuse rate of mobile phones and tablets at home increases with the increase of school stage. Totally 16.30% of students use mobile phones for online learning. The screen overuse rate of those who have not been diagnosed with myopia was lower than that of those who have been diagnosed during home study( OR=0.77, P <0.05). The higher the parents educational level was, the lower the screen overuse rate of children during the weekends became( P <0.05). In any period, the high proportion of screens used in homework and poor home screen eye environment increased the risk of screen overuse and poor eye hygiene ( P <0.05). Parental good behavior was conducive to reducing the risk( OR= 0.65-0.97, P <0.05). When the family had regulation on the screen use time, the implementation of laxity would increase the risk of screen overuse ( OR=1.18-2.48, P <0.05).
Conclusion:The screen overuse rate of urban primary and middle school students during home study is high, and a certain proportion of students still use mobile phones for online learning. The proportion of screens used in homework, home screen eye environment and screen use management are related to screens overuse. More attention should be paid to those with myopia and low educational level of parents.
