EID during the last 12 months was reported by14.3 % (n=330) (girls 16.9 vs. boys 11.8 %, p<0.001). Of all the children reporting EID, 48 % reported wheezing and 30 % rhinitis during the last year, and 39 % had ever had physician diagnosed asthma. Children with EID and asthma used bronchodilators and inhaled corticosteroids (ICS) to a larger extent than children with EID but no diagnosis of asthma (bronchodilators; 27.3 vs. 11.3%, p<0.01 and ICS; 31.2 vs. 4.4%, p<0.001). Only 12.4 % of the total population (n=2312) reached the international physical activity recommendations (≥1 hour/day, 7 days/week on a moderate to vigorous level). 13% among children with EID and 12.3% in children without EID reached the recommendations (p=0.72). Conclusion: Self reported exercise induced dyspnea is common in children and the majority of those children do not have an asthma diagnosis or asthma treatment. Only a minority of Swedish children have a self reported physical activity level that is in line with international recommendations. ER -
