【摘要】 目的 比较新冠肺炎疫情前后宿迁市小学生筛查性近视率, 为近视防控及科普宣教提供依据。 方法 于2019 与2020年采用整群抽样方法对宿迁市39所小学的学生进行眼健康体检, 包括测量裸眼视力、非睫状肌麻痹电脑验光, 分 别对76 823,76 039名6~12岁小学生进行统计分析, 比较2年筛查性近视率在不同人口学特征下的差异。 结果 疫情前 后筛查性近视率分别为30.2%, 36.9%, 2次检查均得出筛查性近视率随年龄增加而增加, 女生近视率 (32.3%, 40.0%)高于 男生 (28.3%, 34.2%), 城市学生近视率 (34.3%, 41.5%)高于农村(26.5%, 32.2%)。各年龄阶段近视率增加均明显, 其中以 9~11岁增加最多 (增加量为 8.6~10.7 百分点), 不同性别、城乡小学生近视率增加均明显, 女生、城市小学生增加最多 (分 别增加 7.7, 7.2 百分点)。 结论 疫情后宿迁市小学生筛查性近视率是 2019 年的 1.2 倍, 在不同人口学特征下均增加, 疫情 后近视现状不容乐观。
