目的 了解贵阳市大中小学生对新型冠状病毒肺炎(以下简称新冠肺炎)相关知识、防护行为情况,为学校开展新冠肺炎疫情防控工作提供参考。方法 2020年9月,采用分层整群随机抽样方法,抽取贵阳市3个区19所学校,采用问卷调查方式对5 330名小学四年级至大学三年级学生开展新冠肺炎相关知识和防护行为调查。结果 贵阳市学生新冠肺炎通过呼吸道传播和密切接触传播的知识知晓率分别为89.5%(4 768/5 330)和79.5%(4 237/5 330)。贵阳市学生在出现发热等症状时坚持上课的比例,在不同地区差异有统计学意义(χ²=25.937,P<0.001),不同学段的差异有统计学意义(χ²=149.524,P<0.001),是否住校之间差异具有统计学意义(χ²=9.996,P=0.007)。98.5%的学生到人群密集地方时佩戴口罩。在公共场所咳嗽、打喷嚏时,职高生和大学生行为正确的比例分别为56.1%和57.3%。职高生和大学生外出回家(宿舍)后每次都洗手的比例分别为29.9%和35.1%。结论 贵阳市大中小学生对新冠肺炎相关知识知晓率较高,防护行为依从性参差不齐,应根据不同特征学生存在的薄弱情况,开展学校健康教育工作。
