Cigarettes and other tobacco-related smoking products have traditionally been a major ignition source for residential fire deaths. In the United States, all 50 states and the District of Columbia have passed laws requiring that cigarettes self-extinguish if they are not being smoked (so-called fire-safe cigarette laws). The purpose of this study was to quantify the association between state-level implementation of fire-safe cigarette legislation and the rate of residential fire death.
Poisson regression was used to analyze state-years data. Main intervention: Implementation dates for fire-safe cigarette legislation in each state.
Residential fire mortality rate.
Implementation of fire-safe cigarette legislation was associated with a 19% reduction in overall residential fire mortality rates, adjusted for demographic differences between states (rate ratio = 0.81, 95% confidence interval: 0.79, 0.84). This is approximately similar to the estimated proportion of residential fire deaths in which smoking materials are an ignition source (23%). Legislation implementation was associated with a protective effect for every age, sex, race, and ethnicity strata that we examined. State-specific residential fire mortality death rates decreased (defined as a drop of at least 5%) in 32 states after fire-safe cigarette legislation was implemented. In 12 states there was either less than a 5% decrease or an increase, and seven states had insufficient deaths to evaluate state-level changes.
Implementation of fire-safe cigarette is associated with reductions in residential fire mortality rates.
香烟及其他与烟草相关的吸烟产品一直是住宅火灾死亡的主要火源。在美国，所有50个州和哥伦比亚特区都已通过法律，要求香烟在未被吸食时自行熄灭（所谓的防火香烟法）。本研究的目的是量化州一级实施防火香烟立法与住宅火灾死亡率之间的关联。
采用泊松回归分析州年数据。主要干预措施：每个州防火香烟立法的实施日期。
住宅火灾死亡率。
实施防火香烟立法与总体住宅火灾死亡率降低19%相关，对各州之间的人口差异进行了调整（率比=0.81，95%置信区间：0.79，0.84）。这与吸烟材料作为火源导致的住宅火灾死亡估计比例（23%）大致相似。立法实施对我们研究的每个年龄、性别、种族和族裔阶层都有保护作用。在实施防火香烟立法后，32个州的特定州住宅火灾死亡率下降（定义为至少下降5%）。在12个州，下降幅度小于5%或有所上升，7个州的死亡人数不足以评估州一级的变化。
实施防火香烟与降低住宅火灾死亡率相关。
