OBJECTIVES The impact of lung cancer screening on smoking is unclear, especially in deprived populations who are underrepresented in screening trials. The aim of this observational cohort study was to investigate whether a community-based lung cancer screening programme influenced smoking behaviour and smoking attitude in socio-economically deprived populations. MATERIAL AND METHODS Ever-smokers, age 55-74, registered at participating General Practices were invited to a community-based Lung Health Check (LHC). This included an assessment of respiratory symptoms, lung cancer risk (PLCOm2012), spirometry and signposting to stop smoking services. Those at high risk (PLCOM2012≥1.51%) were offered annual low-dose CT screening over two rounds. Self-reported smoking status and behaviour were recorded at the LHC and again 12 months later, when attitudes to smoking were also assessed. RESULTS 919 participants (51% women) were included in the analysis (77% of attendees); median deprivation rank in the lowest decile for England. At baseline 50.3% were current smokers. One-year quit rate was 10.2%, quitting was associated with increased baseline symptoms (adjOR 2.62, 95% CI 1.07-6.41; p = 0.035) but not demographics or screening results. 55% attributed quitting to the LHC. In current smokers, 44% reported the LHC had made them consider stopping, 29% it made them try to stop and 25% made them smoke less whilst only 1.7% and 0.7% said it made them worry less about smoking or think it acceptable to smoke. CONCLUSIONS Our data suggest a community-based lung cancer screening programme in deprived areas positively impacts smoking behaviour, with no evidence of a 'licence to smoke' in those screened.

参加基于社区的肺癌筛查会影响贫困人群的吸烟行为。

目的肺癌筛查对吸烟的影响尚不清楚，尤其是在筛查试验中代表性不足的贫困人群中。这项观察性队列研究的目的是调查以社区为基础的肺癌筛查计划是否会影响社会经济匮乏人群的吸烟行为和吸烟态度。材料和方法邀请参加本活动的一般执业者登记的55-74岁的吸烟者参加以社区为基础的肺部健康检查（LHC）。这包括对呼吸道症状，肺癌风险（PLCOm2012），肺活量测定和停止吸烟服务的路标的评估。高危人群（PLCOM2012≥1.51％）接受了两轮年度低剂量CT筛查。LHC记录了自我报告的吸烟状况和行为，然后在12个月后再次记录，同时还评估了对吸烟的态度。结果分析包括919名参与者（51％的女性）（77％的参与者）；中位数剥夺排名在英格兰最低的十分位数中。在基线时，当前吸烟者为50.3％。一年戒烟率为10.2％，戒烟与基线症状增加相关（adjOR 2.62，95％CI 1.07-6.41； p = 0.035），而不是人口统计学或筛查结果。55％归因于大型强子对撞机。在目前的吸烟者中，有44％的人表示LHC使他们考虑停止吸烟，有29％的人认为他们试图戒烟，有25％的人说他们减少了吸烟，而只有1.7％和0.7％的人说他们减少了对吸烟的担忧或认为可以接受抽烟。结论我们的数据表明，在贫困地区开展基于社区的肺癌筛查计划会对吸烟行为产生积极影响，而没有“吸烟许可证”的证据。
