流感大流行后北京市普通人群流感相关知识、行为和技能的现况调查研究

A post-pandemic survey on knowledge, practice and skill related to influenza in the general population of Beijing

目的了解2009年流感大流行后北京市普通人群流感相关知识、行为和技能的现况，为北京市未来制定流感防控策略提供依据。方法在2011年1月期间，采用多阶段分层整群系统抽样的方法，在北京市6个区县抽取普通人群作为调查对象，采用统一标准的调查问卷进行调查。结果共有13286名调查对象参与了本次调查，其中城区6442名（48．5％）。在知识方面，仅有36．2％的调查对象掌握发热体温标准，且以60岁以上年龄组的比例最低（32．2％），不同年龄组和地区间差异具有统计学意义（P〈0．001）。仅有45．6％的调查对象认为接种流感疫苗对预防流感最有效。在行为方面，有93．5％的调查对象在公共场所咳嗽或打喷嚏时会遮挡，然而有11．9％的60岁以上老年人不会遮挡。当自己或他人因出现流感样症状前往医院就诊时，有50．1％的调查对象几乎不或从不戴口罩。在所有调查对象中，2008年、2009年和2010年流感疫苗的接种比例分别为18．1％、23．4％和18．7％，且以60岁以上老年人的接种比例最高（P〈0．001）。在技能方面，分别有48．1％和47．5％的调查对象能全部看懂药品说明书和血常规化验单，有76．4％的调查对象能正确使用体温计，且皆以60岁以上老年人和郊区调查对象的比例最低（P〈0．001）。结论2009年流感大流行后北京市普通人群已经正确掌握了部分流感相关知识、行为和技能，然而在某些方面仍有待进一步提高，尤其对于老年人与郊区人群。
