目的评价戒烟干预对戒烟门诊求助者烟草相关知识、态度和行为（知、信、行）的影响。方法以2008年10月至2013年8月解放军总医院戒烟门诊就医的未使用戒烟药物的吸烟者为研究对象，戒烟门诊医师首诊时为吸烟者进行≥30min的面对面咨询和心理干预，之后1周、1个月、3个月和6个月时共进行4次随访电话干预（每次15～20min）。对照组为2012年8月至2013年8月解放军总医院健康医学中心某病区常规查体的吸烟者，基线和随访时均不进行干预。比较基线和1年随访时干预组和对照组烟草相关知、信、行的变化情况。结果干预组和对照组分别纳入414例和213例研究对象。意向性分析显示，干预组1年随访烟草相关知、信方面共有5个变量的知晓／同意率高于基线。两组的1年随访时点戒烟率分别为4．7％和27．3％。logistic多元回归分析显示，1年随访时戒烟率与暴露于戒烟干预、女性、尼古丁依赖评分低和烟草相关知识及态度正向变化（吸烟导致心脏病、应该禁止各种形式的烟草产品推广、吸烟浪费金钱和酒楼、饭店应该全面禁烟）共7个变量呈正相关，其OR值（95％CI）分别为2．85（2．00～4．07）、3．34（1．23～9．07）、2．78（1．64～4．72）、2．30（1．03—5．15）、5．33（1．47～19．32）、6．32（1．56—25．62）和10．47（2．25～48．84）。结论戒烟门诊求助者的烟草危害认知水平普遍较高，通过系统化戒烟干预，部分吸烟者知识及态度有了一定提高。烟草相关知识及态度的有益转变，有利于提高戒烟率。
