目的准确记录吸烟者戒烟的数量、戒烟尝试的时间、戒烟计划的流行程度和戒烟的认真考虑。我们使用国际烟草控制政策评估四国调查（ITC-4）的7波纵向数据。我们考虑了7年研究中的点患病率数据和累积患病率。我们还从最近一段时间内开始尝试戒烟的报告中得出了戒烟活动的年度估计，以控制有偏见的回忆。设置澳大利亚、加拿大、英国和美国。参与者共有21,613名吸烟者被分七批招募。测量报告的终生戒烟尝试，每年戒烟尝试，尝试的长度，从上次尝试开始的时间，尝试失败的频率，戒烟计划和认真考虑戒烟。大约40.1% （95% CI: 39.6-40.6）的吸烟者报告在某一年中尝试戒烟，平均尝试2.1次。基于自由回忆，这意味着每个吸烟者平均每年尝试戒烟0.82次。仅根据前一个月进行的估计，以调整回忆偏差，表明每年大约每个吸烟者尝试一次。与戒烟有关的活动非常普遍，超过三分之一的吸烟者在一个月内报告了与戒烟有关的想法或行动。超过一半的被调查吸烟者最终成功戒烟至少1个月，其中大多数戒烟超过6个月。结论：吸烟者对戒烟考虑甚多，并多次尝试戒烟失败。许多人能够持续很长一段时间，但他们仍然复发。更多的注意力需要集中在将戒烟相关的活动转化为长期的戒断上。
Aims To document accurately the amount of quitting, length of quit attempts and prevalence of plans and serious thought about quitting among smokers. Design We used longitudinal data from 7 waves of the International Tobacco Control Policy Evaluation Four Country Survey (ITC-4). We considered point-prevalence data and cumulative prevalence over the 7 years of the study. We also derived annual estimates of quit activity from reports of quit attempts starting only within more recent time-frames, to control for biased recall. Setting Australia, Canada, the United Kingdom and the United States. Participants A total of 21 613 smokers recruited across seven waves. Measurements Reported life-time quit attempts, annual quit attempts, length of attempts, time since last attempt started, frequency of aborted attempts, plans to quit and serious thought about quitting. Findings Around 40.1% (95% CI: 39.6-40.6) of smokers report attempts to quit in a given year and report an average of 2.1 attempts. Based on free recall, this translates to an average annual quit attempt rate of 0.82 attempts per smoker. Estimates derived only from the preceding month to adjust for recall bias indicate an annual rate of approximately one attempt per smoker. There is a high prevalence of quit-related activity, with more than a third of smokers reporting thoughts or actions related to quitting in a given month. More than half the surveyed smokers eventually succeeded in quitting for at least 1 month, and a majority of these for over 6 months. Conclusions Smokers think a great deal about stopping and make many unsuccessful quit attempts. Many have been able to last for extended periods and yet they still relapsed. More attention needs to be focused on translating quit-related activity into long-term abstinence.
