ObjectivesThis paper examined the stability over time of daily cigarette consumption of continuing smokers and explored factors that might account for the patterns of change in consumption using a latent growth curve（LGC）analysis approach.MethodsData come from the first 5 waves of the International Tobacco Control Four-Country Survey，carried in Canada，United States，United Kingdom，and Australia where a cohort of over 2，000名来自每个国家的吸烟者进行了招募和随访，每年与replenish.ResultsRaw数据显示，持续吸烟者表现出显着的急剧下降，每天的香烟在前2波，其次是一个温和的线性下降，消费在研究期间的其余波。香烟消费量的这种变化模式最好使用分段线性LGC模型进行建模。澳大利亚的基准消费水平最高，联合王国最低，尽管这4个国家的下降率相似。年龄大于55岁，并已作出至少1戒烟尝试与更大的下降率在consumptionsConclusionsContinuing吸烟者谁不愿意或无法戒烟可以尝试减少他们的每日卷烟消费量随着时间的推移。即使不成功也要尝试戒烟以及在工作和家庭中经历禁烟等因素可能有助于减少这一群体的吸烟，这表明关注这些因素的干预措施，沿着提供戒烟帮助，可能会大大提高他们完全戒烟的机会。
ObjectivesThis paper examined the stability over time of daily cigarette consumption of continuing smokers and explored factors that might account for the patterns of change in consumption using a latent growth curve (LGC) analytic approach.MethodsData come from the first 5 waves of the International Tobacco Control Four-Country Survey, conducted in Canada, the United States, the United Kingdom, and Australia where a cohort of over 2,000 smokers from each country were recruited and followed up annually with replenishment.ResultsRaw data revealed that continuing smokers showed a marked steep decline in cigarettes per day during the first 2 waves followed by a gentler linear decline in consumption over the remaining waves of the study period. This pattern of change in cigarette consumption was best modelled using a piecewise linear LGC model. Baseline consumption level was highest in Australia and lowest in the United Kingdom, although the rate of decline was similar across the 4 countries. Being older than 55 years and having made at least 1 quit attempt were related to greater rate of decline in consumption.ConclusionsContinuing smokers who are unwilling or unable to quit smoking can and do attempt to reduce their daily cigarette consumption over time. Factors such as making a quit attempt even if unsuccessful and experiencing smoking bans at work and at homes can contribute to reduced smoking among this group, which suggests that interventions focusing in on these factors, along with providing cessation help, may greatly improve their chances of quitting smoking altogether.
