This report presents detailed information on the National Asthma Survey (NAS), a module of the State and Local Area Integrated Survey program conducted by the Centers for Disease Control and Prevention's (CDC) National Center for Health Statistics. NAS, sponsored by the CDC's National Center for Environmental Health, was designed to produce national prevalence estimates of adults and children with asthma; to describe the health, socioeconomic, behavioral, and environmental predictors that relate to controlling asthma better; and to characterize the content of care and limitations of persons with asthma. National prevalence estimates were constructed to be consistent with those produced from the CDC's National Health Interview Survey (NHIS), although prevalence estimates for subpopulations may or may not be consistent with NHIS.
Two separate random-digit-dial telephone studies were fielded: a national study and a four-state study in Alabama, California, Illinois, and Texas. Children aged 0-17 years and adults aged 18 years and over were included in both studies. The screening procedure differed between the studies. Percentages can be generated for the four states combined or for each state separately. A substudy was conducted in the national study to examine the accuracy of proxy reports of asthma.
Data were collected from February 2003 to March 2004. A total of 955 detailed asthma interviews were completed in the national study and 5,741 in the four-state study. A data file has been released for each study that contains asthma, health, and demographic data, as well as sampling weights. The weighted overall response rates were 47.2% for the national sample and 48.5% for the four-state sample.
本报告提供了有关国家哮喘调查（NAS）的详细信息，NAS是疾病控制与预防中心（CDC）国家卫生统计中心开展的州和地方综合调查项目的一个模块。由CDC国家环境卫生中心赞助的NAS旨在得出全国哮喘成人和儿童的患病率估计值；描述与更好地控制哮喘相关的健康、社会经济、行为和环境预测因素；并描述哮喘患者的护理内容和局限性。构建的全国患病率估计值与CDC的国家健康访谈调查（NHIS）得出的估计值一致，不过亚人群的患病率估计值可能与NHIS一致，也可能不一致。
开展了两项单独的随机数字拨号电话研究：一项全国性研究以及在阿拉巴马州、加利福尼亚州、伊利诺伊州和得克萨斯州进行的四州研究。两项研究均纳入了0至17岁的儿童和18岁及以上的成年人。两项研究的筛查程序有所不同。可以生成四个州合并的百分比，也可以分别生成每个州的百分比。在全国性研究中进行了一项子研究，以检验哮喘代理报告的准确性。
数据收集时间为2003年2月至2004年3月。全国性研究共完成了955次详细的哮喘访谈，四州研究完成了5741次。已针对每项研究发布了一个数据文件，其中包含哮喘、健康和人口数据以及抽样权重。全国样本的加权总回复率为47.2%，四州样本的加权总回复率为48.5%。
