Abstract

Objective To investigate the relationship between classroom lighting and poor vision of students in primary and secondary schools in Tianjin, and to provide reference for targeted prevention measures for comprehensive school eye health programmes. Methods A total of 623 classrooms and 24 713 students in 89 primary and secondary schools in Tianjin were selected using stratified cluster sampling method in Sep.to Oct. of 2020. The illuminometer was used to monitor the lighting environment of the classroom, and the standard logarithmic vision light box was used to detect the naked eye vision of students. Chi-square test, variance analysis and binary Logistic regression were used in SPSS software. Results Rate of low vision among primary and secondary school students in Tianjin was 67.86%. The qualification rate of blackboard reflectance, blackboard average illumination, blackboard illumination uniformity, desk average illumination and desk illumination uniformity were 58.11%, 53.13%, 73.19%, 66.61% and 75.12%, respectively. Univariate analyses showed that the blackboard reflectance, blackboard average illumination, desk average illumination, and desk illumination uniformity were associated with low vision among students(χ²=311.29, 62.54, 61.71, 6.59, P < 0.05). Multivariable Logistic regression analysis showed that blackboard reflectance, average illumination of blackboard and desk were associated with higher risk of poor vision[OR(95%CI)=1.19(1.11-1.27), 1.27(1.17-1.37), 1.11(1.02-1.20), P < 0.05]. Conclusion Prevalence of low vision among primary and secondary school students in Tianjin is relatively high. Blackboard reflectance, average illumination of blackboard and desk are the important determinants for poor vision of primary and secondary school students. Creating effective classroom lighting scheme is crucial for vision health among students.
