A Quarter of a Century Howdid it start?
In schoolbooks in early 1980:s Asthmaprevalence 2%
In schoolbooks in early 1980:s Asthmaprevalence 2% and so waschronicbronchitis
Aims at start in 1985: Howcommon are OADs? - asthma? - chronicbronchitis? and itsobstructive form? - airwayallergies? And what are theirmain determinants? -
Aims at start in 1985: Howcommon are OADs? - asthma? - chronicbronchitis? and itsobstructive form? - airwayallergies? And what are theirmain determinants? A prevalencestudy in threestages - A cross-sectional postal questionnairesurvey - Structuredinterviews and lungfunction tests - Validation studies includingmethacholine tests

The first yearswere turbulent • The Central Hospital´schiefphysician: • ”Such studies have not beendone in Sweden previously • and should not be donehere, and not by us”

Norrbotten, Sweden • Half of smokers develop COPD sooner or later.1 • 1-2 smokers of 100 develop COPD every year; the corresponding proportion among never smokers is 1-2 of 1000.2 • One fourth of incident cases of COPD has a rapid decline in lung function.3 • Different phenotypes of COPD have different prognosis. 4 • The annual societal costs in Sweden of COPD amounts to about 10 billion SEK. 5 1 Lundbäck B, Respir Med 2003 2 Lindberg A, Chest 2007. 3 Lindberg A, Chest 2005 4 Lundbäck B, COPD 2009. 5 Jansson S-A, Chest 2002
