Analysis on poor vision among primary and middle school students in a city from 2018 to 2022
Objective To explore the current visual acuity status of primary and secondary school students in a city from 2018 to 2022,so as to provide implications for the of policies on prevention and control measures for poor vision.Meth-ods Using whole cluster sampling,health checkups were conducted on all school students in the city during September-November each year for 2018 to 2022 school year,including height,body mass,naked eye vision,and basic eye examina-tion.Differences in the detection rate of poor vision across years,gender,school segments,and age were analyzed using the x2 test.Results The detection rate of poor vision among adolescents was 58.11%,with a trend of increasing and then decreasing from 2018 to 2022(x2=837.74,P<0.001),with the highest rate of poor vision in 2020.The detection rate of poor vision among female students(61.50%)was higher than that of male students(54.91%).There was a gradual increase in the detection rate of poor vision with increasing grade level among students of different cohorts(x2=806 503.47,P<0.001).The overall rate of poor vision showed an increasing trend with age(x2=672 731.05,P<0.001).Conclusion The current status of vision among primary and secondary school students is an urgent issue worth discussing,with a higher detection rate for girls than for boys,an under-age phenomenon,and a higher detection rate of se-vere visual ill-health.
