Johansson H, et al. - In order to gain knowledge about the development of exercise-induced airway symptoms (including wheeze, cough, chest and throat tightness, hoarseness, and stridor) from adolescence to early adulthood, researchers determined the prevalence, incidence, and remission of the above-mentioned symptoms in adolescents, over a five-year period. Of 3,838 adolescents (aged 12–13 years) interrogated, 1,002 responded (43.4%). Over a five-year period, the prevalence of exercise-induced airway symptoms increased by twofold. At both time points (at baseline and follow-up), females were more likely to report symptoms. Symptom remission was reported by more males as compared to females. At follow-up, asthma prevalence was higher in females as compared at baseline, while this was not the case with men. This implies a sex difference in prevalence at follow-up. An increased risk of reporting symptoms at follow-up was observed in relation to smoking and baseline respiratory symptoms.
