What is already known about this topic? Myopia prevalence among Chinese children and adolescents ranks among the highest globally. Although numerous studies have investigated myopia risk factors, findings remain inconsistent across populations. What is added by this report? This study demonstrates that overall myopia prevalence among primary and secondary school students in Zhejiang Province reached 68.87% in 2023, with high myopia affecting 5.82% of students. Notably, regular consumption of a meat and egg-based breakfast emerged as a protective factor against myopia odds ratio (OR)=0.96, 95% confidence interval (CI): 0.92, 0.99. What are the implications for public health practice? Effective myopia prevention requires intersectoral collaboration to reduce academic burden, promote outdoor activities, and implement early screening programs with targeted interventions for high-risk children.
