Refractive Progression and Related Factors in Myopic School-age Children in Ethnic Minority Areas of Yunnan
Objective To understand the refractive progression of myopic school-aged children in ethnic minority areas of Yunnan and explore related factors.Methods Based on an existing cohort,a first follow-up survey was conducted from October 2020 to June 2021 involving 1,774 students selected from three ethnic minority areas:Dali City(Bai ethnic group),Lijiang Ancient Town(Naxi ethnic group),and Menghai County in Xishuangbanna(Dai and Hani ethnic groups).Among them,816 myopic school-aged children at baseline were selected as research subjects to analyze changes in refractive error(△SE)and the degree of refractive progression(classified as rapid △SE and slow △SE)over one year.Binary logistic regression was used to analyze the influencing factors of refractive progression.Results After one year of follow-up,the change in refractive error for myopic school-aged children was-0.63(-1.00,-0.25)D,with 518 children experiencing rapid △SE and 298 children experiencing slow △SE.Comparisons by educational stage indicated that Dai ethnic group children in primary school were more likely to experience rapid △SE than those in junior high school(P<0.05).Logistic regression results showed that school-age children of Naxi ethnic group(OR=1.879,95%CI:1.132～2.999),and those who used their eyes in the classroom during breaks(OR=1.541,95%CI:1.088～2.181)were at higher risk of rapid refractive progression(P<0.05).Children of school age who engage in outdoor activities for at least 3 hours during the day(OR=0.539,95%CI:0.340～0.853)and those who frequently consume animal liver(OR=0.596,95%CI:0.399～0.892)have a lower risk of rapid myopic progression(P<0.05).Conclusion Myopic school-aged children in ethnic minority areas of Yunnan exhibit rapid refractive progression,with significant ethnic differen-ces.The refractive progression in these children is closely related to lifestyle habits,highlighting the need for targeted myopia prevention and control measures and research for children and adolescents in ethnic minority areas of Yunnan.
