目的：报告不同国家吸烟者家庭中无烟家庭政策的流行情况、趋势和决定因素，并估计这些政策对戒烟的影响。设计：国际烟草控制（ITC）四国调查（ITC-4）的两波，通过电话对吸烟者进行队列调查。第一波研究于2002年10月/ 12月进行，样本广泛，有代表性，来自以下四个国家：加拿大、美国、英国和澳大利亚的2000多名成年（>= 18岁）吸烟者，其中75%的人在平均7个月后接受第二波随访。关键指标：家庭吸烟限制水平（两波）。结果：澳大利亚吸烟者最有可能生活在无烟家庭中，而英国吸烟者最不可能（34% vs 15%）。在两波浪潮之间，无烟家庭的数量有所增加。Logistic回归表明，吸烟者报告无烟家庭或实施无烟政策的主要独立预测因素包括家庭因素，如有孩子，特别是年幼的孩子，以及家庭中有其他不吸烟的成年人。对无烟公共场所的积极态度和/或报告的无烟公共场所的存在是拥有或实施无烟家庭的独立预测因素，支持吸烟限制的社会传播模型。在第1波时的戒烟意图和在第1波和第2波之间的戒烟活动与第1波和第2波之间实施禁令有关。第1波禁令的存在与第2波尝试戒烟的人的成功比例显著增加有关。预测模型与国家之间没有显著的相互作用。结论：无烟公共场所似乎刺激了无烟家庭的采用，这一策略与戒烟尝试的频率增加以及戒烟尝试的成功有关。
Objective: To report on prevalence, trends and determinants of smoke-free home policies in smokers' homes in different countries and to estimate the effects of these policies on smoking cessation.Design: Two waves of the International Tobacco Control (ITC) Four Country Survey (ITC-4), a cohort survey of smokers conducted by telephone. Wave 1 was conducted in October/ December 2002 with broadly representative samples of over 2000 adult (>= 18 years) cigarette smokers in each of the following four countries: Canada, the United States, the United Kingdom, and Australia, 75% of whom were followed up at Wave 2 on average seven months later.Key measures: Levels of smoking restrictions in homes ( both waves).Results: Australian smokers were most likely to live in smoke-free homes and UK smokers least likely (34% v 15% at Wave 1). Levels of smoke-free homes increased between waves. Logistic regressions indicated that the main independent predictors of smokers reporting smoke-free homes or implementation of a smoke-free policy between waves included household factors such as having a child, particularly a young child, and having other non-smoking adults in the household. Positive attitudes to smoke-free public places and/or reported presence of smoke-free public places were independent predictors of having or implementing smoke-free homes, supporting a social diffusion model for smoking restrictions. Intentions to quit at Wave 1 and quitting activity between survey waves were associated with implementing bans between Waves 1 and 2. Presence of bans at Wave 1 was associated with significantly greater proportions of quit attempts, and success among those who tried at Wave 2. There was no significant interaction between the predictive models and country.Conclusions: Smoke-free public places seem to stimulate adoption of smoke-free homes, a strategy associated with both increased frequency of quit attempts, and of the success of those attempts.
