济宁市某医学院医学生PM2.5相关知识知晓情况调查

目的了解医学生对PM2.5相关知识的知晓情况,探索PM2.5知晓情况的影响因素,为提高医学生的环保意识提供理论依据。方法 2012年6月采用整群抽样方法对济宁某医学院950名医学生进行问卷调查。结果调查950名医学生,对PM2.5的来源知晓率为89.10%,PM2.5加重呼吸系统炎症知晓率为85.84%,PM2.5使慢性病死亡率增加知晓率为84.04%。女生对PM2.5相关知识的知晓率一般高于男生（P〈0.05）,其中有关PM2.5的好发季节、PM2.5诱发心肌梗塞及PM2.5使慢性病死亡率增加等知识知晓情况差别有统计学意义（P〈0.05）。临床与预防专业的学生对PM2.5纳入空气质量监测、PM2.5影响胎儿发育的知晓率大于精神及其他专业（P〈0.05）。不同年级医学生对PM2.5称为细颗粒物、是一种严重污染物、纳入空气质量监测、加重呼吸系统炎症、引发高血压及增加慢性病死亡率等知识知晓情况差别有统计学意义（P〈0.05）。结论医学生对PM2.5相关知识的知晓率较高,但个别问题知晓率偏低。

Survey on the Awareness of Knowledge about PM2.5 Among Medical College Students,Jining City

Objective To understand the awareness rate of knowledge about PM2.5 among medical college students,and explore the related factors of PM2.5 awareness rate, so as to provide theoretical basis for improving the medical students＇ awareness of environmental protection. Methods A total of 950 medical college students extracted by cluster sampling were surveyed by questionnaire in June,2012. Results The awareness rate of the sources of PM2.5 was 89.10% ,the awareness rate of PM2.5 aggravating rate of respiratory inflammation was 85.84%. The awareness rate of chronic disease mortality increase by PM2.5 was 84.04%. The awareness rate of PM2.5 related knowledge of girls is generally higher than the boys（ P 〈0.05） ,such as PM2.5 frequent season,PM2.5 inducing myocardial infarction,PM2.5 increasing chronic disease mortality（P〈0.05）. The awareness rate of students in majors of clinic and prevention was greater than mental and other major students, such as PM2.5 included into the air quality monitoring, PM2.5 affecting fetal development （ P 〈0.05）. The awareness rate of medical students in different grades was statistically different（ P 〈0.05）, such as PM2.5 included into the air quality monitoring, PM2.5 aggravating respiratory inflammation, PM2.5 increasing chronic disease mortality and so on. Conclusion The awareness rate of medical students about PM2.5 related knowledge is higher, but the individual knowledge rate is low.
