The reason for the substantial geographic variation in the prevalence of childhood asthma is not known.
To investigate the association between exposure to cigarette smoking in the home and childhood asthma at the state-level, toward improving current understanding of geographic variation in childhood asthma rates.
Data were drawn from the National Children's Health Survey (NCHS, 2003), a representative sample (n = 102,000) of youth 0 to 17 years of age in the United States. Household smoking and asthma in children were reported by parents. Air quality for each state was obtained from Environmental Protection Act (EPA) reports, and state-level poverty reports were obtained from the US Department of Agriculture.
Household smoking was associated with a statistically significant increase in risk of asthma among children at the state level (p = 0.026). This association did not appear to be influenced by outdoor air quality at the state level or socioeconomic position.
These results are the first to show a link between cigarette smoking in the home and childhood asthma at a state-level in the United States.
儿童哮喘患病率存在显著地理差异的原因尚不清楚。
在州层面调查家庭中接触吸烟与儿童哮喘之间的关联，以增进当前对儿童哮喘发病率地理差异的理解。
数据取自全国儿童健康调查（NCHS，2003年），这是美国0至17岁青少年的代表性样本（n = 102,000）。儿童家庭吸烟情况和哮喘情况由家长报告。各州的空气质量数据来自《环境保护法》（EPA）报告，州层面的贫困报告来自美国农业部。
在州层面，家庭吸烟与儿童哮喘风险的统计学显著增加相关（p = 0.026）。这种关联似乎不受州层面室外空气质量或社会经济地位的影响。
这些结果首次在美国州层面表明家庭吸烟与儿童哮喘之间存在联系。
