1997年重新设计的国家健康访谈调查(NHIS)影响了美国儿童哮喘患病率的估计。1997年0-17岁儿童哮喘发作患病率估计为5.4%。重新设计前的NHIS儿童期哮喘患病率估计在1995年达到峰值,为7.5%。目前尚不清楚这种差异是否反映了调查方法的变化或哮喘患病率的变化。为了检验NHIS重新设计对儿童哮喘患病率估计的影响,作者分析了1988年NHIS,其中包含两组哮喘问题:1996年之前使用的核心调查和儿童健康补充(CHS),其中问题与重新设计的1997年NHIS中的问题更相似。作者测量了1988年核心和CHS儿童哮喘患病率估计值之间的差异,以计算1997-2000年NHIS估计值的通货膨胀因子。1988年CHS问题产生的哮喘患病率估计值比1988年核心问题低19-34%,这取决于用于评估差异的方法。通过这些差异对1997年哮喘发作患病率估计值进行膨胀,得到1997年修订的估计值,范围为6.5%(95%置信区间:5.6%,7.5%)至7.3%(95%置信区间:6.4%,8.2%)。1997年NHIS哮喘问题的变化可能解释了1995年和1997年之间哮喘患病率估计值的差异。
The 1997 redesign of the National Health Interview Survey (NHIS) affected US childhood asthma prevalence estimates. The 1997 asthma attack prevalence estimate for children 0-17 years was 5.4%. Pre-redesign NHIS childhood asthma period prevalence estimates peaked in 1995 at 7.5%. It is unclear whether the difference reflects the change in survey methodology or changing asthma prevalence. To examine the impact of the NHIS redesign on childhood asthma prevalence estimates, the authors analyzed the 1988 NHIS that contained two sets of asthma questions: the core survey used until 1996 and the Child Health Supplement (CHS) with questions more similar to those in the redesigned 1997 NHIS. The authors measured the difference between 1988 core and CHS childhood asthma prevalence estimates to calculate an inflation factor for 1997-2000 NHIS estimates. The 1988 CHS questions produced asthma prevalence estimates 19-34% lower than the 1988 core question, depending on the methodology used to assess the difference. Inflating the 1997 asthma attack prevalence estimate by these differences yielded modified 1997 estimates ranging from 6.5% (95% confidence interval: 5.6%, 7.5%) to 7.3% (95% confidence interval: 6.4%, 8.2%). The change in the 1997 NHIS asthma questions likely explains much of the difference in asthma prevalence estimates between 1995 and 1997.
