Abstract

Objective To understand the vision status of primary and secondary school students in Beijing, in order to provide scientific reference for myopia prevention and control. Methods From 2018 to 2021, a stratified cluster sampling method was used to monitor myopia among 191 293 primary and secondary school students selected from 6 urban areas and 10 suburban areas in Beijing.Myopic screening was in accordance with the"standards for children and adolescents myopic screening", and was measured by an automatic desktop computer optometer under non-cycloplegic conditions.Statistical analysis was used by Chi-square test. Results The total myopia rate of primary and middle school students in Beijing from 2018 to 2021 were 60.7%, 57.6%, 59.2% and 59.7%, respectively.In 2018, the myopia rates of primary school students, middle school students, regular high school students and vocational high school students were 38.3%, 77.3%, 88.3% and 73.2% respectively.In 2019, they were 34.7%, 76.4%, 87.7% and 72.0%, respectively; in 2020, they were 37.5%, 76.8%, 86.8%, 74.9%;in 2021, they were 38.7%, 77.4%, 86.5% and 74.9% respectively.Significant differences in educational stage were observed (χ²=7 386.07, 11 104.28, 9 850.08, 9 714.59, P < 0.01).From 2018 to 2021, the overall myopia rate of girls (62.1%) was higher than that of boys (56.5%)(χ²=613.75, P < 0.01).The myopia rate of girls were higher than that of boys in each year, and significant differences in educational stage were observed, respectively (χ²=120.47, 163.47, 168.01, 162.24, P < 0.01).The overall myopia rate of urban students (63.0%) was higher than that of suburban students (56.0%)(χ²=978.82, P < 0.01).The myopia rate of urban students were higher than that of suburban students every year, and significant differences in educational stage were observed, respectively (χ²=86.71, 240.96, 302.56, 409.30, P < 0.01). Conclusion The detection rate of myopia rate of primary and middle school students in Beijing is still high.It is necessary to strengthen the publicity and intervention of poor visual acuity in primary and middle school students, especially among urban area students, with the aim of effectively control and reduction in the myopia rate, and the improvement of student visual health.
