目的 分析影响戒烟门诊男性吸烟者成功戒烟的相关因素.方法 由经培训的医生对自愿在戒烟门诊就医的吸烟者进行面对面咨询和心理干预,之后进行1周、1个月、3个月和6个月4次标准化的电话随访干预.6个月随访时主要分析指标为“7天时点戒烟率”和“3个月持续戒烟率”及其相关影响因素.结果 2008年10月至2012年12月共有355人人组,其中255人完成6个月随访.符合方案样本（n=255）的“7天时点戒烟率”和“3个月持续戒烟率”分别为34.9％和25.5％,而意向性分析样本（n=355）则分别为25.1％和18.3％.logistic多元分析结果显示,戒烟成功与首诊呼气一氧化碳测试水平低、戒烟信心自评分高、买烟费用低、伴有医生诊断的烟草相关慢性病呈正相关.戒烟失败的主要原因是无法克服烟瘾、需要用吸烟缓解工作压力、受到身边其他吸烟者的影响,以及缺乏戒烟的心理准备和毅力等.结论 吸烟量较少、戒烟自信心强、患有烟草相关慢性病的男性吸烟者较易成功戒烟,应为吸烟者提供定期的随访干预服务,增强其戒烟动机和创造良好的戒烟环境.
