【摘要】 目的了解成都市居民PM2.5的知、信、行,为政府制定相关的政策提供科学依据。方法 2015-03-01/15期间,按照统一设计的调查问卷,对2 100名社区居民以匿名的形式进行调查。主要调查居民对大气颗粒物PM2.5知识知晓情况、对PM2.5健康危害认知情况,以及在空气污染时是否采取自我防护措施及方式。率的比较采用单因素卡方检验,多因素分析采用非条件logistic回归分析。结果共调查2 100人,有效应答2 005人,应答率95.5%,其中男863人、女1 142人,年龄≥18岁,60岁以上老年人仅占9.0%。文化程度大多集中在大专文化(51.0%)。职业分布名列前3位分别是:干部职员为45.0%、教师及专业技术人员为17.9%、其他人员为16.3%。多因素非条件logistic回归分析结果显示,文化程度和职业是影响雾霾相关知识知晓率的主要因素(α<0.05);影响对雾霾健康危害认知的主要因素是文化程度(α<0.05);年龄、文化程度、职业和性别都是影响对雾霾防护知识掌握情况的主要因素(α<0.05)。结论政府和相关部门有必要加强雾霾天气危害的宣传力度和采取相关措施,引起社会各方重视,提高居民在雾霾天气时的防护意识。更多还原
