To determine the prevalence of asthma and respiratory symptoms among Swedish cross-country skiers in early adolescence in comparison to a population-based reference group of similar ages.\n                    <jats:italic>Methods<\/jats:italic>\n                    . A postal questionnaire on asthma, asthma medication, allergy, respiratory symptoms, and physical activity was distributed to Swedish competitive cross-country skiers aged 12\u201315\u2009years (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u2009331) and a population-based reference group (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u20091000).

The prevalence of self-reported asthma (physician-diagnosed asthma and use of asthma medication in the last 12\u2009months) and the prevalence of reported wheezing during the last 12\u2009months were 23% and 25%, respectively, among skiers, which were significantly higher than the values reported in the reference group (12% and 14%). Skiers exercised more hours\/week than the reference group. Among adolescents with self-reported asthma, neither the usage of asthma medications nor the level of asthma control according to the Asthma Control Test differed between skiers and the reference group.\n                    <jats:italic>Conclusions<\/jats:italic>\n                    .
