Higher prevalence but later age at onset of asthma in cross-country skiers compared with general population

Abstract

Asthma prevalence in 351 competitive cross-country skiers compared with 338 population controls. Asthma was more prevalent in skiers (25.9% vs. 9.2%, p < 0.001) but had a later onset (median 13.0 vs. 8.0 years). 89% of skiers with asthma had well-controlled disease. 82.4% used inhaled corticosteroids regularly.
