Asthma, chronic bronchitis and respiratory symptoms : prevalence and important determinants
The Obstructive Lung Disease in Northern Sweden study's (OLIN) overall aim is prevention of obstructive airways diseases; asthma, chronic bronchitis and chronic obstructive pulmonary disease (COPD). The first part of the OLIN study was a cross- sectional study in three phases, which aimed to es...

Those reporting symptoms suspicious of asthma or chronic bronchitis (n=l,340), together with a stratified sample (n=315) of those not suspected of having the diseases according to the postal questionnaire, were invited to structured interviews and lung function tests. The prevalence of asthma, 5- 6% according to both the postal questionnaire and to the structured interview, prompted a validity study, which included bronchial provocation tests.
