目的了解某医科大学学生对雾霾相关认知及自我保护意识的现况。方法 2016年12月采取多阶段分层整群随机抽样从某医科大学抽取3个专业的595名在校学生进行自填式问卷调查。结果调查595名学生,回收有效问卷574份,有效回收率为96.50%。529名学生(92.20%)感知校周边雾霾存在,493名学生(85.90%)对学校所在地雾霾情况关注度良好,91.40%的学生认为雾霾会诱发呼吸系统疾病,322名学生(56.00%)有佩戴N95口罩的意识,且不同性别、不同年级学生对不同种类口罩佩戴率差异有统计学意义(P<0.01)。164名学生(28.50%)会刻意在室内摆放一些可能具有防霾效果的物品,不同性别、不同年级、不同专业学生雾霾天口鼻清洗频率差异有统计学意义(P<0.01);83名学生(14.40%)会刻意调整自己的饮食结构以预防雾霾对身体的危害。结论某医科大学多数学生对雾霾具有良好的认知,但部分学生的雾霾防护知识有待增强。
Objective To understand the status quo of awareness of smog-related cognition and self-protection among students in a medical university. Methods In December 2016, a random sample of 595 students enrolled from 3 medical schools in a medical university was taken by means of random sampling using stratified multistage stratified clustering. Results A total of 595 students were surveyed, 574 valid questionnaires were collected, and the effective recovery rate was 96.50%. 529 students (92.20%) felt haze around the school, 493 students (85.90%) were concerned about the haze situation in their school, 91.40% of them thought that haze would induce respiratory diseases, 322 students (56.00% ) Wear N95 masks awareness, and different gender, different grades of different types of masks wear rate difference was statistically significant (P <0.01). 164 students (28.50%) deliberately placed some items that may have anti-haze effect indoors. There was significant difference in the frequency of mouth and nose cleaning between smokers and students of different sexes, grades, and specialties (P <0.01); 83 Students (14.40%) will deliberately adjust their diet to prevent the haze on the body. Conclusion Most students in a medical university have a good understanding of smog and haze, but some students have yet to gain knowledge of smog protection.
