Abstract:
Objective:To analyze the screening myopia status and risk assessment of influencing factors among primary and secondary school students in Hainan Province in 2021, so as to providea reference for formulating myopia prevention and control intervention strategies and measures of school in Hainan Province.
Methods:According to the requirements of the national project monitoring plan, the stratified cluster random sampling method was used to investigate the myopia screening and related influencing factors in 5 monitoring points of common diseases monitoring of students in Hainan Province from September to December 2021, and 12 075 valid questionnaires were obtained for analysis. Using stratified random method, all samples were divided into training data set and test data set according to the ratio of 7∶3, and regression analysis was conducted to verify the robustness of the results.
Results:In 2021, the screening myopia detection rate of primary and secondary school students in Hainan Province was 44.3%, among which the screening myopia detection rate of students in the middle and good districts was higher (53.5%), that of students in urban areas (52.6%) was higher than that of students in suburban counties (34.9%), and that of girls (51.7%) was higher than that of boys ( 37.3% ). The detection rate of Han students (47.7%) was higher than that of ethnic minorities, and the difference between groups was statistically significant( χ 2=152.71, 378.77, 167.81, 251.94, P <0.01); The detection rate of screening myopia increased with the increase of the school level( χ 2=1 421.66, P <0.01). Multivariate Logistic regression analysis showed that the results of the two sets of data were consistent, and being in a higher grade, daily frequency of eye exercises <2 times, poor habit of short distance use of eyes (lying or lying on the stomach reading or watching electronic screen), having one or both parents with myopia were positively correlated with screening myopia( P <0.05). For boys, time spent doing homework/reading and writing after school every day <2 h, time spent using mobile electronic devices per day <1 h, students with 1 h and daily sleep duration≥9 h were negatively correlated with the incidence of screening myopia( P <0.05).
Conclusion:The risk of screening myopia increases with the increase of school age in Hainan, and relevant departments should strengthen targeted intervention and prevention for students with high risk of screening myopia.
