A cross-sectional study was carried out on a random sample of 2,216 schoolchildren 9 to 14 yr of age to determine the prevalence of exercise-induced airway narrowing (EIAN) in a Mediterranean town (Matarb).
A complementary case-control study measured the association between EIAN and respiratory symptoms.
A free-running test was performed during school time.
Peak expiratory flow rate (PEFR) was measured at rest and at 2, 5, 10, and 15 min after exercise.
A total of 136 of 2,056 satisfactory runs showed a decrease of PEFR equal to or higher than 15% at each of these times after exercise.
Five more children developed wheezing during running and were considered to have EIAN.
