Prevalence and trend of low vision among primary and secondary school students in Wuhan from 2019 to 2020

  • 摘要:   目的  了解新型冠状病毒肺炎(新冠肺炎)疫情居家隔离及线上学习后,武汉市中小学生视力不良检出率情况,为中小学生视力防控提供科学依据。  方法  2020年6月19日至7月6日,利用武汉市青少年视力低下防制(预防控制)中心设计的在线视力筛查工具对156 783名中小学生进行视力筛查,同时调查前1周学生室内外活动及视屏时间。学生相应的2019年新冠肺炎疫情暴发前的裸眼视力从学校视力监测记录中获取。  结果  2020年视力不良检出率(51.04%)高于2019年(43.04%)(χ2=68 944.95,P < 0.01)。经协变量调整后,相对于低分位数的网课时间、视屏娱乐时间、室内活动时间、室外活动时间,高分位数的各类活动时间对于视力不良OR值(OR值95%CI)分别为1.17(1.  13~1  .20)、1.07(1.04~1.10)、0.67(0.65~0.69)、0.62(0.60~0.64)。结论武汉市中小学生2020年视力不良检出率较2019年显著增高,应加强中小学生视力保护的广泛干预,优先考虑改善体育活动机会和减少多种屏幕行为的政策措施。
