Studies have documented movement of secondhand smoke (SHS) between units in multi-unit buildings, but none has focused on owner-occupied units in common-interest communities (CICs). In Minnesota, approximately 170,000 households (8%) live in such units. CIC households may experience long-term SHS exposure because owner-occupants typically live in the same unit for many years.
This study estimated the prevalence of SHS incursion in CICs and assessed residents' attitudes toward SHS incursions and interest in smokefree policies.
A stratified sample of Minnesota CIC owner-occupants was surveyed in 2009, with analysis in 2010-2011. Data were weighted to account for differing sampling, response, and coverage rates by stratum, then calibrated to population control totals for housing type, age, and smoking status.
The response rate was 35.6%, with 495 completions. Twenty-eight percent of households reported SHS incursion into their unit in the preceding 6 months; 59% of these said this bothers them a lot. Only 6% report that their CIC has a smokefree policy for residents' units. Forty-two percent would prefer such a policy whereas 26% would prefer smoking-permitted. Sixty-three percent definitely and 17% probably would choose a no-smoking building over a smoking-permitted building if they were buying a new unit, and 46% would be willing to pay more for such a unit.
Secondhand smoke incursion is common in CICs, and interest in smokefree CICs greatly exceeds the supply. Given the known health risks of SHS exposure, tobacco control efforts in multi-housing should address CICs as well as rental households.
研究已经记录了二手烟（SHS）在多单元建筑物之间单元之间的移动，但没有一项研究集中在共同利益社区（CIC）的业主居住单元上。在明尼苏达州，大约有 17 万户家庭（8%）居住在这些单元中。CIC 家庭可能会长期暴露于 SHS 之下，因为业主通常会在同一单元中居住多年。
本研究估计 CIC 中 SHS 入侵的流行率，并评估居民对 SHS 入侵的态度以及对无烟政策的兴趣。
2009 年对明尼苏达州 CIC 业主进行了分层抽样调查，并于 2010-2011 年进行了分析。数据经过加权处理，以考虑不同层的抽样、回应和覆盖率的差异，然后根据住房类型、年龄和吸烟状况的人口控制总数进行校准。
回应率为 35.6%，有 495 个完整回复。28%的家庭报告在前 6 个月内有 SHS 入侵其单元；其中 59%的人表示这让他们非常困扰。只有 6%的家庭报告说他们的 CIC 有针对居民单元的无烟政策。42%的人更倾向于这样的政策，而 26%的人更倾向于允许吸烟。如果他们正在购买新单元，63%的人肯定会选择无烟建筑，而 17%的人可能会选择无烟建筑，而不是允许吸烟的建筑，并且 46%的人愿意为此类单元支付更高的价格。
二手烟入侵在 CIC 中很常见，对无烟 CIC 的兴趣大大超过了供应量。鉴于 SHS 暴露的已知健康风险，多住房的烟草控制工作应同时解决 CIC 和出租家庭的问题。
