Abstract Background Schools play an organizational role in managing myopia-related behavioral habits among students. We evaluated the effects of school myopia management measures on myopia onset and progression in a school-based prospective 1-year observational study. Methods In total, 8319 children from 26 elementary schools were included. Online questionnaire completed by a parent, in which school myopia management experience including outdoor activities in recess or physical education class, teachers’ supervision, and teaching facilities. Variables were defined as implemented well or poorly, according to the Comprehensive Plan to Prevent Myopia among Children and Teenagers. Children underwent ophthalmic examinations, and the incidence and progression of myopia from 2019 to 2020 were estimated. Multilevel logistic regression models were constructed to analyze the association between school management measures and myopia development in 8,9 years and 10,11 years students. Results From 2019 to 2020, the incidence of myopia among primary school students was 36.49%; the mean difference of spherical equivalent in myopic children was − 0.29 ± 1.22 diopters. The risk of incident myopia was reduced by 20% in 8,9 years participants with well-implemented class recess compared with those with poorly implemented class recess (adjusted odds ratio [aOR]: 0.80, p = 0.032). PE outdoor time was significantly associated with myopia incidence in 10,11 years students (aOR: 0.76, p = 0.043). Compared with poorly implemented reading and writing posture, desk and chair height, 10,11 participants with well-implemented desk and chair height were less likely to have rapid myopic progression (p = 0.029, p = 0.022). Conclusion In Shanghai, children’s myopia is associated with better implementation of school myopia management measures. The present findings suggest that outdoor activities during class recess or PE class, providing suitable desks and chairs, and adequate instruction in reading and writing postures might protect against pathological eye growth. An age-specific myopia prevention and control programs in school is of primary importance.

Objective::To explore the refractive status along with relevant factors during the fetal and infancy period in 9-month-old infants, and to provide evidence for early prevention and intervention of refractive errors.Methods::This study analyzed refractive screening data accumulated by the Minhang District Maternal and Child Health Care Institution, Shanghai, from 2012 to 2019. In all, 16 746 infants aged 9 months were included in the description of refractive status. Relevant factors before 9 months of age were collected by child health examination records and questionnaire survey data. Chi-square tests and multivariate regression models were used to analyze the association of factors during the fetal and infancy periods in 9-month-old infants with suspicious refractive errors.Results::The P5- P95 of the refractive sphere for infants aged 9 months was +0.50 D-+3.00 D, and the P5 of the refractive cylinder for infants aged 9 months was -2.50 D. Detection rates of suspected myopia, hyperopia, astigmatism, and anisometropia were 13.46%, 11.13%, 25.58%, 8.29%, respectively. Birth during the winter and frequent contact with electronic devices increased the risk of suspected myopia (adjusted OR were 1.35, 1.55 respectively). Birth during the summer or autumn, prematurity and a physique greater than the P80 quantile at 9 months of age increased the risk of suspected hyperopia (adjusted OR were 1.67, 1.62, 1.80, 1.22 respectively). Birth during the summer, a physique greater than the P80 quantile and artificial feeding at 9 months of age increased the risk of suspected astigmatism (adjusted OR were 1.92, 1.42, 1.19, respectively). Outdoor activities of more than 0.5 h per day decreased the risk of suspected refractive errors (adjusted OR=0.711-0.803). Conclusion::Detection rates of suspected refractive errors in infants aged 9 months are between 8% and 25%, among which astigmatism is most significant. Infants with high-risk factors such as prematurity, parents with refractive errors and large physique should be the focus of refractive screening and follow-up.
