Abstract: Objective To study the impact of badminton juggling on the myopia of lower-grade primary school students and to provide a basis for developing myopia intervention strategies for children and adolescents．Methods By using the convenience sampling method,182 third-grade students from four classes in a primary school in a district of Guangzhou were selected as subjects．After completing the baseline survey,the four classes were divided into an intervention group（2 classes,91 students）and a control group（2 classes,91 students）using a random number table．The intervention group was arranged to participate in badminton juggling sports activities,while the control group followed the original teaching plan without ball games．The study compared the screening rate of myopia,the rate of poor vision,and the degree of myopia progression before and after the study in both groups．Results On baseline,there were no statistically significant differences between the two groups in terms of age,gender,rate of screening myopia,poor vision,and myopia grading（P>0.05）．After 12 months,there was no statistically significant difference in the spherical equivalent（SE） comparison between the two groups（P>0.05）．However,the uncorrected distance visual acuity（UDVA） of the control group after 12 months was significantly lower than that of the intervention group,and both △UDVA and △SE were significantly higher than those of the intervention group,with all differences being statistically significant（P<0.05）．Incidence of screening myopia in the control group （29.13%）,the cumulative rate of screening myopia（49.45%）,the cumulative rate of poor vision （68.13%）,and the degree of myopia progression was significantly higher than those in the intervention group,which had incidence of screening myopia at 7.69%,the cumulative rate of screening myopia at 34.07%,cumulative rate of poor vision at 52.74%．All these differences were statistically significant（P<0.05）．Conclusions Badminton juggling can slow down vision deterioration,reduce the incidence and severity of myopia in lower grade primary school students．Schools can flexibly apply these findings in conjunction with factors that contribute to myopia to prevent its occurrence and development．
