Effects of school myopia management measures on myopia onset and progression among Chinese primary school students

This prospective 1-year observational study involving 8319 children from 26 elementary schools in Shanghai aimed to evaluate the impact of school myopia management measures on myopia onset and progression. The study considered various factors such as outdoor activities, teacher supervision, and teaching facilities. Results showed a 36.49% incidence of myopia among primary school students from 2019 to 2020. Well-implemented class recess and physical education (PE) outdoor time were associated with a 20% and 24% reduced risk of incident myopia in 8–9 years and 10–11 years students, respectively. Additionally, appropriate desk and chair height, along with proper instruction in reading and writing postures, were linked to a decreased risk of myopic progression in 10–11 years children. The study emphasized the importance of outdoor activities during recess or PE class, suitable desks and chairs, and effective guidance in preventing myopia. The findings contribute to understanding the role of school-based measures in managing myopia among students in Shanghai.
