Abstract：Objective To investigate the current situation of myopia among primary and middle school students in urban and rural areas of Hainan Province, and to explore the differences in factors influencing myopia between urban and rural areas so as to provide a scientifical and theoretical basis for further precise grading prevention and control of youth myopia. Methods A multi-stage sampling method was used to select 13,193 students from 31 primary and middle schools in 18 cities and counties of the province from October to November 2019. Vision examination, refractive examination and questionnaire survey were conducted. Multi-level Logistic model was used to analyze the factors influencing myopia among the students. Results The overall myopia rate in the students in Hainan Province was 52.49%, and the myopia rate was higher in urban areas than in rural areas (56.57% vs. 49.04%, χ2=74.366, P<0.001). There was school clustering in myopia. The results of multi-level model fitting revealed that among urban students, the risk of myopia was relatively high in girls (OR=1.762, 95%CI:1.494-2.079), older students (OR=1.181, 95%CI:1.062-1.312), students with duration of sedentary study after school on school day ≥ 2 hours (OR=1.188, 95%CI:1.032-1.367), and students using electronic devices on the weekend ≥ 1 h (OR=1.207, 95%CI:1.028-1.418) (all P<0.05). Among rural students, the risk of myopia was higher in girls (OR=1.724, 95%CI:1.499-1.983), older students (OR=1.198, 95%CI:1.123-1.279) and students with duration of sedentary study on the weekend ≥ 2 hours(OR=1.195, 95%CI:1.078-1.325)(all P<0.05). The longer the sleep time, the relatively lower the risk (OR=0.887, 95%CI:0.822-0.957, P<0.05). Conclusion The myopia rate of the primary and middle school students in Hainan Province was relatively low, and there were differences between urban and rural areas. It is necessary to strengthen home-school cooperation in terms of homework, time spent using electronic devices and sleep time, and practically and effectively intensify myopia prevention and control.
