In 2012, North Dakota enacted a comprehensive statewide law prohibiting smoking in enclosed public places. Disparities in tobacco control exist in rural areas. This study's objective was to determine the extent to which the passage of a comprehensive, statewide, smoke-free law in a predominantly rural state influenced tobacco smoke pollution in rural and nonrural venues.
A longitudinal cohort design study comparing the levels of tobacco smoke pollution before and after passage of the statewide smoke-free law was conducted in 64 restaurants and bars statewide in North Dakota.
Particulate matter with a median aerodynamic diameter of <2.5 μm (a valid atmospheric marker of tobacco smoke pollution) was assessed.
A significant 83% reduction in tobacco smoke pollution levels occurred after passage of the law. Significant reductions in tobacco smoke pollution levels occurred in each of the rural categories; however, no difference by rurality was noted in the analysis after passage of the law, in contrast to the study before passage.
To our knowledge, this was the largest, single, rural postlaw study globally. A comprehensive statewide smoke-free law implemented in North Dakota dramatically decreased the level of tobacco smoke pollution in bars and restaurants.
2012年，北达科他州颁布了一项全州范围的综合性法律，禁止在封闭公共场所吸烟。农村地区在烟草控制方面存在差异。本研究的目的是确定在一个以农村为主的州通过一项全面的全州范围无烟法律对农村和非农村场所烟草烟雾污染的影响程度。
采用纵向队列设计研究，比较北达科他州全州64家餐馆和酒吧在全州无烟法律通过前后的烟草烟雾污染水平。
评估中位空气动力学直径<2.5μm的颗粒物（烟草烟雾污染的有效大气标志物）。
法律通过后，烟草烟雾污染水平显著降低了83%。每个农村类别中的烟草烟雾污染水平均显著降低；然而，与法律通过前的研究相比，法律通过后的分析未发现农村地区存在差异。
据我们所知，这是全球最大的单项农村地区法律实施后研究。北达科他州实施的全面全州范围无烟法律显著降低了酒吧和餐馆的烟草烟雾污染水平。
