Chronic obstructive pulmonary disease (COPD) : prevalence, incidence, decline in lung function and risk factors
The Obstructive Lung Disease in Northern Sweden (OLIN) Studies started in 1985 as an epidemiological project with the aim to detect preventable risk factors for obstructive lung diseases and allergy. In recent years there has been a focus also on obstructive sleep apnoea syndrome (OSAS) and chronic...

A postal questionnaire survey was performed in 1985/86, 1992 and in 1996.

The prevalence of COPD in the general population sample (cIII) in ages <45 was 4.1%, 11.6%, 9.1%, and 5.1% according to the criteria of BTS1 , ERS2 , GOLD3 , and ATS4 respectively.
