目的 了解2019年和2021年北京市某区儿童青少年近视率变化趋势,为儿童青少年近视防控工作提供科学依据。方法 采用分层整群随机抽样法分别于2019年和2021年抽取北京市某城区幼儿园、小学、初中、高中、职高,4所幼儿园7所学校共5 263名学生进行视力水平检测,其中2019年2 611人,2021年2 652人。结果 2021年筛查性近视的总体检出率为60.7%(1 609/2 652),高于2019年的57.9%(1 512/2 611),两者差异具有统计学意义(χ2=5.840,P=0.016)。同时,2021年幼儿园、小学二、五年级、初中一年级学生的筛查性近视上升更为明显。结论 北京市某区儿童青少年近视率特别是低年龄儿童近视率在两年期间呈上升趋势。
Abstract
Objective To evaluate the trend in myopia rate of children and adolescents in a district of Beijing in 2021 and 2019 and then provide scientific evidence for prevention and control of myopia in children and adolescents. Methods A total of 5 263 students from 4 kindergartens,7 schools including primary schools,junior high schools,senior high schools and vocational schools in an urban area of Beijing were selected by stratified cluster random sampling method in 2019 and 2021,of which 2 611 were in 2019 and 2 652 in 2021. Results The total physical examination rate of screening myopia in 2021 was 60.7% (1 609/2 652),higher than 57.9% (1 512/2 611) in 2019,and the difference was statistically significant (χ2=5.840,P=0.016).At the same time,in 2021,the screening myopia of students in kindergarten,the second and fifth grades of primary school,and the first grade of junior high school increased more significantly. Conclusion The myopia rate of children and adolescents in a district of Beijing,especially the myopia rate of low-age children,has shown an upward trend in the two years.
