To examine the association between tobacco smoking and residential-fire mortality and to investigate whether this association is explained by the confounding effects of selected socioeconomic factors (ie, educational attainment and median household income).
An ecological analysis relating state-level residential-fire mortality to state-level percentages of adults who smoke was conducted. Negative binomial rate regression was used to model this relationship, simultaneously controlling for the selected socioeconomic factors.
After educational attainment and median household income had been controlled for, smoking percentages among adults correlated significantly with state-level, population-based residential-fire mortality (estimated relative rate for a 1% decrease in smoking = 0.93; 95% CI 0.89 to 0.97).
Mortality from residential fires is high in states with high smoking rates. This relationship cannot be explained solely by the socioeconomic factors examined in this study.
研究吸烟与住宅火灾死亡率之间的关联，并调查这种关联是否可由选定的社会经济因素（即教育程度和家庭收入中位数）的混杂效应来解释。
进行了一项生态分析，将州级住宅火灾死亡率与州级成年人吸烟百分比相关联。使用负二项式率回归对这种关系进行建模，同时控制选定的社会经济因素。
在控制了教育程度和家庭收入中位数之后，成年人吸烟百分比与州级基于人群的住宅火灾死亡率显著相关（吸烟率每降低1%的估计相对率=0.93；95%可信区间为0.89至0.97）。
吸烟率高的州住宅火灾死亡率也高。这种关系不能仅由本研究中所考察的社会经济因素来解释。
