Material: Eight hundred men and women aged 20-44 years, living in the capital Reykjavik and suburbs. Methods: Participants answered a questionnaire, underwent skin prick testing for atopy, spirometry and a test for bronchial hyperresponsiveness (BHR) by methacholine challenge. Results: There was 77% attendance. Altogether 16.6% reported wheezing or whistling at any time in the last 12 months. Altogether 32 (5.6%)answered yes to "Have you ever had asthma?" and the diagnosis had been confirmed by a doctor in all but four. Fourteen (2.5%) had suffered from an attack of asthma in the last 12 months wheras only 0.9% were currently using anti asthmatic drugs. BHR was found among 8.7% and atopy on skin testing among 20.5%. BHR was more common among those with airflow obstruction and three times more common among the atopic participants (18% vs. 6%, p<0.01). By using a history of wheezing during the last 12 months together with BHR and/or a history of doctor confirmed asthma the prevalence of current asthma was found to be 5% in our sample. The main predictive factors for asthma were a history of breathlessness and nighttime breathing symptoms, but also atopy, airflow obstruction and a maternal history of asthma. Conclusion: Even by using a conservative defination, asthma is a common disorder among 20-44 years old Icelanders whereas the use of asthma medication is rather uncommon in this population. Tilgangur: Að meta algengi astma og einkenna frá öndunarfærum. Efniviður: Átta hundruð einstaklingar 20-44 ára á Stór-Reykjavíkursvæðinu. Aðferðir: Spurningalisti, húðpróf, blásturspróf og mæling á auðreitni í berkjum. Niðurstöður: Þátttakendur voru 570 (77%). Tæplega 17% höfðu tekið eftir pípi (ýli) eða surgi fyrir brjósti á síðastliðnum 12 mánuðum. Þrjátíu og tveir (5,6%) játuðu spurningunni: Hefur þú nokkurn tímann fengið ...
