ABSTRACT

Objective@#To investigate the prevalence and influencing factors of poor eyesight among primary and middle school students in Tongzhou District, Beijing Municipality, so as to provide the evidence for developing control strategies for poor eyesight among primary and middle school students.@* Methods@#Grades 3 to 6 students in district- and township-level primary schools, grades 1 to 3 students in district- and township-level junior high schools, and grades 1 to 3 district- and township-level high schools were sampled in Tongzhou District using the stratified cluster sampling method from 2020 to 2021. Basic information, daily activity, sleep duration and eye-using habits were collected using the specific questionnaires for poor eyesight and influencing factors among students in the 2018 national program for common diseases and health risk factors surveillance program among Chinese students, and the height and body weight were measured. Factors affecting poor eyesight were among primary and middle school students identified using a multivariable logistic regression model. @*Results@#A total of 771 valid questionnaires were recovered, and the respondents included 392 male students (50.84%) and 379 female students (49.16%), and 321 primary school students (41.63%), 228 junior high school students (29.57%) and 222 high school students (28.79%). The prevalence of poor eyesight was 73.54% among the respondents. Multivariable logistic regression analysis showed that education phase (junior high school, OR=2.940, 95%CI 1.931-4.476; high school, OR=5.998, 95%CI 3.701-9.723) , obesity (OR=1.989, 95%CI 1.258-3.146), daily exercise duration of less than 1 h (OR=1.931, 95%CI 1.351-2.760), daily sleep duration of less than 8 h (OR=1.719, 95%CI 1.193-2.477), at least 33 cm distance between a reading book and eyes (sometimes, OR=2.165, 95%CI 1.320-3.550; never, OR=2.634, 95%CI 1.767-3.928) and continuous short-distance eye use duration of 1 h and longer (OR=1.455, 95%CI 1.020-2.078) were associated with poor eyesight among primary and middle school students.@*Conclusions@# The prevalence of poor eyesight is high among primary and middle school students in Tongzhou District. Higher grade, obesity, inadequate exercise and sleep duration and poor eye-using habits may increase the risk of poor eyesight.
