We studied the impact of implementing a comprehensive smoke-free policy in multiunit housing in the Portland, Oregon metropolitan area. Among low-income tenants living in a subset of subsidized multiunit buildings, we evaluated cessation-related behaviors, policy knowledge and compliance, and secondhand smoke (SHS) exposure.
We mailed a self-administered questionnaire to a random sample of 839 current tenants of 17 subsidized buildings 4 months after policy implementation in January 2008 and sent another questionnaire to participants 1 year later. Results are based on 440 tenants who completed both surveys.
We observed a self-reported annualized quit rate of 14.7% over the study period (95% CI = 7.9%-21.6%) compared with a historical quit rate in this population of 2.6% (95% CI = 0.6%-4.5%). Almost half of ongoing smokers reduced their cigarette consumption. More smokers correctly reported policy rules for indoor settings than for outdoor settings; self-reported indoor smoking decreased significantly from 59% to 17%. Among nonsmokers, frequent indoor SHS exposure (multiple times per week) decreased significantly from 41% prepolicy to 17% postpolicy.
The implementation of a smoke-free policy was associated with positive changes in cessation-related behaviors and reduced SHS exposure in this population of low-income adults.
我们研究了在俄勒冈州波特兰大都市区的多单元住房中实施全面禁烟政策的影响。在居住于补贴多单元建筑中的低收入租户中，我们评估了与戒烟相关的行为、政策知识和遵守情况，以及二手烟（SHS）暴露情况。
我们在 2008 年 1 月政策实施后的 4 个月内向 17 栋补贴建筑中的 839 名现有租户随机发送了一份自我管理的问卷，并在一年后向参与者发送了另一份问卷。结果基于 440 名完成了两次调查的租户。
我们观察到，在研究期间，自我报告的年戒烟率为 14.7%（95%CI=7.9%-21.6%），而该人群的历史戒烟率为 2.6%（95%CI=0.6%-4.5%）。近一半的持续吸烟者减少了吸烟量。更多的吸烟者正确报告了室内环境的政策规则，而不是室外环境的规则；自我报告的室内吸烟量从 59%显著下降到 17%。在非吸烟者中，频繁的室内 SHS 暴露（每周多次）从政策前的 41%显著下降到政策后的 17%。
在这个低收入成年人的群体中，实施无烟政策与戒烟相关行为的积极变化和减少 SHS 暴露有关。
