The present study reports on the prevalence of smoke-free homes, the characteristics of participants who adopted a smoke-free home policy, and the association between smoke-free homes and subsequent predictors of smoking cessation.
Data are reported on 4,963 individuals who originally participated in the Community Intervention Trial for Smoking Cessation between 1988 and 1993 and completed follow-up surveys in 2001 and 2005. The relationship between home smoking policy and smoking behavior was examined with a multivariate regression model.
Among those who were smokers at the 2001 follow-up, the percentage reporting that no smoking was allowed in their home increased from 29% in 2001 to 38% in 2005. Smokers most likely to adopt smoke-free home policies between 2001 and 2005 were males, former smokers, and those who had lower levels of daily cigarette consumption (among those who continued to smoke), those with higher annual household incomes, and those with no other smokers in the household. Some 28% of smokers with smoke-free homes in 2001 reported that they had quit smoking by 2005 compared with 16% of those who allowed smoking in their homes (odds ratio [OR] = 1.7, 95% CI = 1.4-2.2), and baseline quitters with smoke-free homes also were less likely to relapse (OR = 0.6, 95% CI = 0.4-0.8).
Smoke-free homes are becoming more prevalent, and they are a powerful tool not only to help smokers stop smoking but also to help keep those who quit from relapsing back to smoking.
本研究报告了无烟家庭的普及率、采取无烟家庭政策的参与者特征，以及无烟家庭与后续戒烟预测因素之间的关联。
报告了4963名个体的数据，这些个体最初于1988年至1993年参与了戒烟社区干预试验，并于2001年和2005年完成了随访调查。使用多元回归模型检验家庭吸烟政策与吸烟行为之间的关系。
在2001年随访时为吸烟者的人群中，报告家中禁止吸烟的比例从2001年的29%增至2005年的38%。2001年至2005年间最有可能采取无烟家庭政策的吸烟者为男性、曾经吸烟者、每日吸烟量较低者（在继续吸烟者中）、家庭年收入较高者以及家中无其他吸烟者的人。2001年家中无烟的吸烟者中，约28%报告称到2005年已戒烟，而家中允许吸烟的吸烟者中这一比例为16%（比值比[OR]=1.7，95%置信区间[CI]=1.4 - 2.2），并且家中无烟的基线戒烟者复发的可能性也较小（OR = 0.6，95% CI = 0.4 - 0.8）。
无烟家庭正变得越来越普遍，它们不仅是帮助吸烟者戒烟的有力工具，也是帮助已戒烟者防止复吸的有力工具。
