目的：在美国，意外一氧化碳（CO）中毒是导致中毒的主要原因。大多数中毒事件发生在住宅环境中，一氧化碳报警器可以防止许多此类事件。该国许多地区都强制使用一氧化碳警报;然而，人们对人口层面遵守和采用此类法令的情况知之甚少。本研究确定了2009年北卡罗来纳州梅克伦堡县居民CO报警的流行率和对2001年CO报警条例的认识。研究方法：在进行的横断面调查中，随机抽取了按住房类型（如单户住宅、多户住宅）分层的家庭样本。每个家庭的一名成年受访者进行了问卷调查，其中包括社会人口和家庭特征，存在的CO报警，CO报警条例的认识。采用多变量分层条件Logistic回归分析数据。结果如下：在214个参与调查的住户（回应率为23.4%）中，145个（67.8%）报称有一氧化碳警报器运作正常，而79个（36.9%）受访者知道一氧化碳警报器条例。知道该条例的受访者比不知道的人有9倍高的几率（95%置信区间，3.3-25.9）有一氧化碳报警。此外，有车库的家庭比没有车库的家庭有2倍以上的几率（95%置信区间，1.0-6.2）有一氧化碳报警。CO警报条例的意识与任何社会人口统计学（例如，年龄、性别、种族、教育、收入）或家庭（例如，房屋所有权、房屋建造年份）特征无关。结论：梅克伦堡县家庭的一氧化碳报警患病率高于全国平均水平，并与CO报警条例的认识。公共卫生工作可能会受益于针对人群采取预防性健康行为的法规。
Objective: Unintentional carbon monoxide (CO) poisoning is a leading cause of poisoning in the United States. Most poisoning cases occur in residential settings and a working CO alarm may prevent many of these events. The use of a CO alarm is mandated in many parts of the country; however, little is known about the compliance and adoption of such ordinances at the population level. This study determined the prevalence of residential CO alarm and awareness of a 2001 CO alarm ordinance in Mecklenburg County, North Carolina in 2009. Methods: A random sample of households stratified by housing type (eg, single-family homes, multifamily homes) was included in a cross-sectional survey conducted. One adult respondent from each household was administered a questionnaire that included information on sociodemographic and household characteristics, presence of a CO alarm, and CO alarm ordinance awareness. Data were analyzed using multivariate stratified conditional logistic regression. Results: Among 214 participating households (response rate, 23.4%), 145 (67.8%) reported having a working CO alarm and 79 (36.9%) of the respondents were aware of the CO alarm ordinance. Respondents who were aware of the ordinance had 9 times higher odds (95% confidence interval, 3.3-25.9) of having a CO alarm than those who were unaware. Also, households with an attached garage had more than 2 times higher odds (95% confidence interval, 1.0-6.2) of having a CO alarm than those without an attached garage. Awareness of the CO alarm ordinance was not associated with any sociodemographic (eg, age, sex, race, education, income) or household (eg, home ownership, home construction year) characteristics. Conclusions: Carbon monoxide alarm prevalence in Mecklenburg County households was higher than the national average and was associated with CO alarm ordinance awareness. Public health efforts might benefit from regulations aimed at population-level adoption of preventive health behaviors.
