Asthma screening of high school athletes: identifying the undiagnosed and poorly controlled.

Background: It is believed that there are many high school-age athletes who have undiagnosed asthma or exercise-induced asthma (EIA). The screening of these athletes for EIA will allow them to be identified and treated.

Objectives: 1) To obtain reliable peak expiratory flow rate (PEFR) measurements and administer questionnaires to high school-age athletes to evaluate their asthma risk.
