The study was conducted to ascertain whether physical education teachers, using a peak flow meter, could reliably screen for exercise-induced asthma (EIA) in children during free running.
DESIGN, SETTING AND SUBJECTS: The study was conducted using a convenience sample of male pupils between the ages of 12 and 18 years. They were tested with a peak flow meter for peak expiratory flow rate (PEFR) and with a flow-volume curve for forced expiratory flow in 1 second (FEV1) before and 10 minutes after a self-paced free running test during physical education classes. Testing was undertaken by teachers using the peak flow meter and by a medical doctor using a flow-volume curve.
Using a 10% decrease in flow parameters (PEFR and FEV1), teachers detected EIA in 14.9% of pupils and the doctor detected EIA in 21.7% of pupils.
We conclude that EIA is common and that teachers using a peak flow meter can detect EIA and thus screen for it; they do, however, underestimate the true magnitude of the problem.
本研究旨在确定体育教师使用峰值流量计能否在儿童自由跑步期间可靠地筛查运动诱发哮喘（EIA）。
设计、地点和研究对象：本研究采用了便利抽样，选取了12至18岁的男性学生。在体育课上进行自定速度的自由跑步测试前和测试后10分钟，用峰值流量计测量他们的呼气峰值流速（PEFR），并用流速-容量曲线测量他们的1秒用力呼气量（FEV1）。测试由使用峰值流量计的教师和使用流速-容量曲线的医生进行。
使用流量参数（PEFR和FEV1）下降10%的标准，教师检测出14.9%的学生患有EIA，医生检测出21.7%的学生患有EIA。
我们得出结论，EIA很常见，使用峰值流量计的教师能够检测出EIA并进行筛查；然而，他们确实低估了问题的实际严重程度。
