To analyze the changes in classroom lighting environment of schools in Suzhou and their impact on refractive progression among primary and secondary school students, so as to provide the basis for accurate provention and control of myopia.
A baseline investigation was conducted in October 2022 by using a stratified cluster random sampling method to recruit primary and secondary school students from Suzhou.A follow-up visit was performed in October 2023.A total of 12 302 students and 360 classrooms that participated in both surveys were included analysis.The visual acuity progression over one year and classroom lighting conditions were assessed.Group comparisons were performed by using the Wilcoxon or Kruskal-Wallis rank-sum, and Chi-square tests.Multivariate Logistic regression was employed to identify the major factors influencing refractive changes.
The compliance rate of average illuminance on classroom blackboard surface increased from 72.22% to 75.28%, while the compliance rate of average illuminance on desks decreased from 89.44% to 87.22%, the overall myopia rate among students rose from 59.63% to 66.99% from 2022 to 2023.The average annual progression of equivalent spherical power (SE) in the right eye of students was-0.25(-0.75, 0.06) D.Significant statistical differences were observed in the annual mean changes across different school levels, regions, baseline refractive statuses, and classroom lighting environment change groups (Z/H=316.59, -8.27, 38.80, 51.01, all P < 0.05).Multivariate Logistic regression analysis showed that pre-myopia, low myopia, junior high school, senior high school, vocational high school, and improved classroom lighting environment were protective factors of reducing the risk of rapid progression in refractive error (OR=0.58, 0.69, 0.81, 0.50, 0.28, 0.82, all P < 0.05).Conversely, female students and rural students had higher risks of rapid myopia progression (OR=1.09, 1.42, both P < 0.05).
Over one-year follow-up, the complance rate of classroom lighting indicators in Suzhou remaines stable, while students'refractive status shows a trend toward myopia.Improving classroom lighting environment can reduce the risk of rapid myopia progression.
