While clean indoor air legislation at the state level is an evidence-based recommendation, only limited evidence exists regarding the impact of clean indoor air policies on state smoking prevalence. Using state smoking prevalence data from 1997 to 2010, a repeated measures observational analysis assessed the association between clean indoor air policies (i.e., workplace, restaurant, and bar) and state smoking prevalence while controlling for state cigarette taxes and year. The impacts from the number of previous years with any clean indoor air policy, the number of policies in effect during the current year, and the number of policies in effect the previous year were analyzed. Findings indicate a smoking prevalence predicted decrease of 0.13 percentage points (p=0.03) for each additional year one or more clean indoor air policies were in effect, a predicted decrease of 0.12 percentage points (p=0.09) for each policy in effect in the current year, and a predicted decrease of 0.22 percentage points (p=0.01) for each policy in effect in the previous year on the subsequent year. Clean indoor air policies show measurable associations with reductions in smoking prevalence within a year of implementation above and beyond taxes and time trends. Further efforts are needed to diffuse clean indoor air policies across states and provinces that have not yet adopted such policies.
虽然州一级的室内空气清洁立法是一项基于证据的建议，但关于室内空气清洁政策对州吸烟率的影响，现有证据有限。利用1997年至2010年的州吸烟率数据，一项重复测量观察性分析评估了室内空气清洁政策（即工作场所、餐厅和酒吧）与州吸烟率之间的关联，同时控制了州香烟税和年份。分析了此前实施过任何室内空气清洁政策的年份数量、当年实施的政策数量以及上一年实施的政策数量的影响。研究结果表明，每多实施一年一项或多项室内空气清洁政策，吸烟率预计下降0.13个百分点（p = 0.03）；当年每实施一项政策，吸烟率预计下降0.12个百分点（p = 0.09）；上一年每实施一项政策，次年吸烟率预计下降0.22个百分点（p = 0.01）。室内空气清洁政策在实施一年内与吸烟率降低之间存在可衡量的关联，这种关联超出了税收和时间趋势的影响。需要进一步努力，在尚未采用此类政策的州和省份推广室内空气清洁政策。
