Abstract：Objective To explore the relationship between sleep duration and myopia among middle and primary school students in Yangzhou City, and to provide references for further improving sleep quality and preventing myopia among middle and primary school students. Methods In 2021, a total of 2,900 students from 4 primary schools (grades 4-6), 4 middle schools and 4 high schools were selected by a stratified cluster random sampling method in Yangzhou City for an investigation. Physical examination was carried out on site according to the National Program for Monitoring Students' Common Diseases and Factors Influencing Health, including measurement of naked eye vision, diopter, height and weight of each subject. An online questionnaire survey was conducted to collect the primary and middle school students' general information, myopic-related behaviors like time for reading and writing after the class, time for outdoor activities and parents' educational levels and myopia, and the length of sleep. Multivariate logistic regression model and correlation analysis were used for analyzing the association between sleep duration and myopia. Results A total of 3,050 questionnaires were sent out, and 2,900 effective questionnaires were retrieved, with a retrieving effective rate of 95.08%. Among them, 1,505 (51.90%) were male students, 1,395 (48.10%) female students, 968 (33.38%) primary school students (grades 4-6), 981 (33.83%) junior middle school students, and 951 (32.79%) high school students. Myopia was detected in 2,175 students, with a detection rate of 75.00%. There were statistically significant differences in the detection rate of myopia between genders, among school stages, body mass indexes, maternal education levels, parents' myopia and time for after-class reading and writing, and between sufficient and insufficient sleep duration (all P<0.05). 1,361 (46.93%) students slept < 8 h per day, 724 (24.97%) 8 h- <9 h, 471 (16.24%) 9 h- <10 h, and 344 (11.86%) ≥10 h. The daily sleep duration showed statistically significant differences among primary and secondary school students in different districts, school stages and genders (all P<0.05). Multivariate logistic regression model analysis displayed that students who slept <8 h per day had a higher risk of myopia than those who slept ≥10 per day (OR=1.407-1.475, 95%CI:1.006-2.053). There was a positive correlation between sleep duration and equivalent bulb degree of left and right eyes (P<0.05) when the students were sleep-deprived. Conclusion The primary and secondary school students' sleep duration is related to myopia, and insufficientdailysleep duration may be a risk factor for myopia. It is suggested that the improvement of insufficient sleep duration can be taken as the key intervention measure to prevent and control myopia.
