Providing an on-site immediate diagnosis of Chronic Obstructive Pulmonary Disease (COPD) and lung age in tobacco smokers could be a motivational tool for smoking cessation. Our aim was to investigate the effects of an abnormal spirometry results on motivational change and subsequent smoking cessation. We conducted a retrospective analysis of smoking status after 3 months of tobacco counseling. Patients were recruited in an addiction outpatient center. Spirometry results were obtained with a portable device during the first visit. The sample was thus divided in 3 groups: COPD, subthreshold-group (no COPD but abnormal lung age) and normal spirometry. Among the three groups, we compared the immediate motivation change, difference in Q-MAT motivation scale score after minus before spirometry (Kruskal-Wallis test) and the smoking status after 3 months (Fisher test). We included 48 patients (37 males, median age 44 years, median cigarette-per-day 20). Spirometry results divided the sample in COPD (N = 13), subthreshold (N = 11) and normal group (N = 24). Mean Q-MAT score change after spirometry was different between groups (p = 0.019), greater in COPD (4.62 ± 3.38) than normal group (1.46 ± 3.11), and lower in patient with a co-occuring hazardous alcohol use (p = 7.6 × 10⁻³). Three-months smoking status was different between spirometry results groups (p = 0.0021). COPD (5/13, 38.5%) and subthreshold patients (6/10, 60.0%) had stopped more frequently than patients from the normal-group (2/22, 9.1%). The effect of immediate spirometry results on motivation to quit varies according to the screened pulmonary damages and hazardous alcohol use. It could be a useful tool in addiction treatment centers.

提供现场即时诊断为吸烟者的慢性阻塞性肺疾病（COPD）和肺年龄可能是戒烟的一种动机工具。我们的目的是研究肺活量测定结果异常对动机改变和随后戒烟的影响。在进行了3个月的烟草咨询后，我们对吸烟状况进行了回顾性分析。在成瘾门诊中心招募患者。肺活量测定结果是在首次就诊时使用便携式设备获得的。因此将样品分为3组：COPD，阈下组（无COPD，但肺年龄异常）和肺活量测定正常。在这三组中，我们比较了减去后的即时动机变化，Q-MAT动机量表得分的差异肺活量测定前（Kruskal-Wallis试验）和3个月后吸烟状态（Fisher试验）。我们纳入了48位患者（37位男性，中位年龄44岁，每天平均吸烟量20）。肺活量测定结果将样品分为COPD（N  = 13），亚阈值（N  = 11）和正常组（N  = 24）。两组之间，肺活量测定后的平均Q-MAT得分变化是不同的（p  = 0.019），COPD（4.62±3.38）高于正常组（1.46±3.11），而同时使用危险酒精的患者则更低（p  = 7.6×10 ^-3）。肺活量测定结果组之间的三个月吸烟状态有所不同（p = 0.0021）。COPD（5/13，38.5％）和阈下患者（6/10，60.0％）的停药频率高于正常组（2/22，9.1％）。立即肺活量测定结果对戒烟动机的影响因所筛查的肺损伤和有害酒精使用而异。它可能是成瘾治疗中心的有用工具。
