Abstract

Objective To investigate the epidemiological characteristics of myopia among primary and secondary school students in Midong District, Urumqi, and to identify the associated factors, so as to provide a basis for formulating corresponding strategies. Methods In November 2024, a stratified cluster sampling design was used to recruit 13 548 students aged 6 - 18 years from 11 primary and secondary schools.Visual acuity and non-cycloplegic refraction were assessed, and spherical equivalent (SE) was calculated.Myopia was defined as unaided visual acuity<5.0 and SE>-0.50 D, and high myopia as SE>-6.00 D (classified as positive if either eye met the criterion).Group differences were compared using the chi-square test.Multivariate logistic regression models were used to examine factors associated with myopia and high myopia. Results A total of 7 249 students were identified with myopia (53.51%), including 180 with high myopia (1.33%).Myopia prevalence was higher in girls than in boys (54.78% vs. 52.33%), was highest in senior high school students (90.39%), and was higher in township schools than in urban schools (57.42% vs. 50.64%), the differences were significant (P<0.05).In multivariate analysis, compared with primary school students, the risk of myopia were significantly higher among junior high school students (OR=1.610) and senior high school students (OR=15.950), and higher among township students (OR=1.999). Compared with Han students, Uygur and Hui students had a higher risk of myopia (OR=1.329,1.151), whereas Kazakh students had a lower risk of mlyopia (OR=0.723)(P<0.001).The risk of high myopia increased with grade level (junior high school: OR=6.343; senior high school: OR=24.407, P<0.001). Conclusions The prevalence of myopia among primary and secondary school students in Midong District is high.Although high myopia is relatively uncommon, its risk rose sharply with grade level.Targeted, tiered prevention and control strategies are warranted, especially for junior/senior high school students and those in township areas.
