Difference between screened myopia in primary school students and reported myopia by their main caregivers
Objective To analyze the prevalence of myopia among primary school students from grade one to grade three in Zhongshan City,and to explore the influencing factors of myopia reporting discrepancies and to provide scientific ba-sis for the prevention and control of early-onset myopia in children and adolescents.Methods From May to July 2023,a multi-stage stratified cluster random sampling method was used to select some primary school students in Zhongshan City of Guangdong Province for questionnaire survey and visual examination.The difference between screened myopia and reported myopia was analyzed by x2 test,and the factors affecting the consistency of myopia results were analyzed by binary logistic regression model.Results The prevalence of myopia identified through systematic screening was 25.3％.In contrast,par-ent-reported prevalence in the same demographic was 12.1％,with an awareness rate among parents of 81.1％.Compared with the first grade,the report consistency rate of the third grade was higher,and the OR value was 1.453(95％CI:1.160-1.819).With poor eye health behavior score as the reference,the consistency rate of general score and good score was higher,and the OR values were 0.524(95％CI:0.423-0.649)and 0.379(95％CI:0.293-0.467),respec-tively.Compared with the non-mydriatic optometry group,the consistency rate of the mydriatic optometry group was higher,and the OR value was 0.615(95％CI:0.455-0.831).Compared with both parents'myopia,the consistent rate of both parents'non-myopia was higher,and the OR value was 0.669(95％CI:0.514-0.872).Taking the mother's education level as primary school and below as the reference,the consistency rate of mother's education level as junior high school,senior high school and technical secondary school and junior college and above was higher,and the OR values were 0.514(95％CI:0.322-0.821),0.355(95％CI:0.222-0.567)and 0.313(95％CI:0.195-0.503),respective-ly.Conclusion Better eye health literacy score and mydriatic optometry are the main factors affecting the consistency of the report.Therefore,health education for parents'myopia prevention and control should be strengthened to improve parents'awareness of children's myopia and the accuracy of the report in the future.
