This study documented the prevalence of exercise-induced asthma (bronchospasm) in rural elementary schools and described the use of a free-running asthma screening test (exercise-challenge) and peak expiratory flow rate measurements for screening in a school setting. Of 437 children screened, 25 (5.72%) had a > or = 15% decrease in post-exercise peak expiratory flow rate which is indicative of exercise-induced asthma. Absenteeism and poverty were associated with findings of exercise-induced asthma. Early detection of exercise-induced asthma in school-age children through screening would facilitate early treatment, enhance exercise-related activities, and decreases school absences.
本研究记录了农村小学运动诱发性哮喘（支气管痉挛）的患病率，并描述了在学校环境中使用自由运动哮喘筛查测试（运动激发试验）和呼气峰值流速测量进行筛查的情况。在接受筛查的437名儿童中，25名（5.72%）运动后呼气峰值流速下降≥15%，这表明存在运动诱发性哮喘。旷课和贫困与运动诱发性哮喘的检查结果相关。通过筛查在学龄儿童中早期发现运动诱发性哮喘将有助于早期治疗，增加与运动相关的活动，并减少学校缺勤。
