目的：评估加拿大图形香烟警告标签对当前成年吸烟者的影响。设计：2001 年 10 月/11 月对加拿大安大略省西南部的 616 名成年吸烟者进行了随机数字拨号电话调查，并进行了三个月的随访。主要结果指标：吸烟行为（戒烟、戒烟尝试和减少吸烟）、戒烟意愿和警告标签的显着性。结果： 几乎所有吸烟者（91%）都表示已阅读警告标签，并且吸烟者对其内容有透彻的了解。我们观察到认知处理指标（吸烟者阅读、思考和讨论新标签的程度）与吸烟者戒烟意图之间存在很强的正相关关系（比值比 (OR) 1.11，95% 置信区间 (Cl) 1.07 至 1. 16；p < 0.001）。最重要的是，认知处理可以预测随访时的戒烟行为。在调整戒烟意向和基线吸烟状况后，在基线时阅读、思考和讨论过新标签的吸烟者更有可能在三个月后戒烟、尝试戒烟或减少吸烟（OR 1.07，95% Cl 1.03 至 1. 12；p < 0.001）。结论：图形香烟警告标签是一种基于人群的有效戒烟干预措施。这些发现丰富了有关健康警语的文献，并为加拿大烟草标签政策的有效性提供了强有力的支持。
Objective: To assess the impact of graphic Canadian cigarette warning labels on current adult smokers.Design: A random-digit-dial telephone survey was conducted with 616 adult smokers in south western Ontario, Canada in October/November 2001, with three month follow up.Main outcome measures: Smoking behaviour (quitting, quit attempts, and reduced smoking), intentions to quit, and salience of the warning labels.Results: Virtually all smokers (91 %) reported having read the warning labels and smokers demonstrated a thorough knowledge of their content. A strong positive relation was observed between a measure of cognitive processing-the extent to which smokers reported reading, thinking about, and discussing the new labels-and smokers' intentions to quit (odds ratio (OR) 1.11, 95% confidence interval (Cl) 1.07 to 1. 16; p < 0.001). Most important, cognitive processing predicted cessation behaviour at follow up. Smokers who had read, thought about, and discussed the new labels at baseline were more likely to have quit, made a quit attempt, or reduced their smoking three months later, after adjusting for intentions to quit and smoking status at baseline (OR 1.07, 95% Cl 1.03 to 1. 12; p < 0.001).Conclusions: Graphic cigarette warning labels serve as an effective population based smoking cessation intervention. The findings add to the growing literature on health warnings and provide strong support for the effectiveness of Canada's tobacco labelling policy.
