Abstract:
Objective:To understand the trend of eye use behavior of students in Suzhou, and to provide basis for comprehensive prevention and control of myopia.
Methods:Stratified cluster random sampling was used to recruit students from grades 4 to 12 in Suzhou from 2018 to 2021. The students general information, eye use behavior, outdoor activities and sleep status were collected through a standardized questionnaire to compare eye use behaviors of students among various groups.
Results:The detection rates of students who watched TV or used computer more than 1 h/d decreased from 2018 to 2021( χ 2 trend =192.25, 95.39, P <0.05), and boys who spend more than 1 h/d on watching TV and using computer accounted for 26.4% and 19.2%, and girls accounted for 21.1 % and 12.8%, respectively in 2021. The proportion of students watching mobile electronic devices≥1 h/d decreased ( χ 2 trend =314.85, P <0.05), and the boys proportion was less than girls with 29.2% and 30.3% respectively, and each grade declined except for vocational high schools. The proportion of students with average reading and writing time after school above 2 h/d had decreased except for vocational school students. In 2021, the proportions of four school periods(primary school, middle school, high school and vocational school) were 22.1%, 47.7%, 65.1% and 11.6% respectively. The proportions of students with good eye habits such as reading with desk lamp and roof lamp, watching computer screen and TV with a safe distance, using eyes at close range for less than 1 h/d and taking a rest had increased ( χ 2 trend =34.19, 62.21, 47.25, 457.50, P ＜0.05), reaching up to 72.2%, 72.3%, 78.6 % and 67.8% respectively in 2021. The proportion of students spending more than 2 h/d on outdoor activities increased ( 27.1 % in 2018 and 30.7% in 2021, χ 2 trend =5.17, P ＜0.05), but only in primary school students, and the rates of boys were higher than girls . There was no improvement in sleep deprivation. The girls who were lack of sleep girls were more than boys, and the proportion of senior high school was higher than that of junior middle school and primary school.
Conclusion:The eye use behaviors of primary and middle school students have improved significantly from 2018 to 2021. However, the problems including insufficient sleep and less outdoor activities still exist. Health education in students aiming at eye use behavior improvement should be strengthened.
