title: [Use of a video questionnaire for assessment of asthma prevalence in school children as part of the ISAAC epidemiological study].
abstract: The aim of this publication is the comparison of the data characterizing asthma prevalence obtained from standardized questionnaire (SQ) and video-questionnaire (VQ) used in epidemiological study ISAAC--Poznań. Number of positive answers to questions concerning wheezing ever, current wheezing, night symptoms were lower in VQ. The percentage of children reporting exercise induced asthma didn't differ in both methods. Severe asthma attacks were reported more frequently in VQ. VQ may eliminate the differences in perception and interpretation of asthma symptoms, but presentation of severe symptoms leads to underestimation of asthma problem.
