Abstract

Objective To understand the correlation between classroom environment in primary and secondary schools in Shaanxi Province with students' myopia, so as to provide the reference for the development of effective strategies for myopia prevention and control in children and adolescents. Methods From November 2022 to March 2023, primary and secondary schools were selected from all districts and counties in 10 cities in Shaanxi Province by a stratified cluster random sampling method. A total of 386 classrooms received environmental hygiene evaluation, and 3 760 students underwent visual examinations using logarithmic visual acuity chart and non dilated computer optometry, as well as questionnaire surveys. The association between classroom environment in primary and secondary schools and screening myopia in students were analyzed by the Logistic regression model. Results A total of 2 299 primary and secondary school students were screened for myopia, with a detection rate of 61.14%. After adjusting factors such as gender, academic stage, sleep time, outdoor activity time, electronic mobile device usage time and homework time after school, the results of multiple Logistic regression analysis showed that the risk of screening myopia among students with unqualified average illuminance on blackboard and uniformity ratio of illuminance of blackboard was 1.24 times (OR=1.24, 95%CI=1.08-1.43) and 1.31 times (OR=1.31, 95%CI=1.06-1.60) higher than that of qualified classrooms respectively (P < 0.05). Subgroup analysis showed that the risk of screening myopia detected by boys in classrooms with unqualified blackboard illumination was 1.26 times (OR=1.26, 95%CI=1.04-1.54) than that of qualified classrooms, the risk of screening myopia detected by girls in classrooms with unqualified blackboard size was 1.55 times (OR=1.55, 95%CI=1.19-2.02) and unqualified blackboard illumination uniformity was 1.38 times (OR=1.38, 95%CI=1.01-1.89) higher than that of qualified classrooms (P < 0.05). Conclusions Teaching environment health of primary and secondary schools in Shaanxi Province need to be improved. The risk increasing of screening myopia among students is related to the size of the blackboard, average illuminance on the blackboard surface and uneven illuminance.
