title: [Prevalence of childhood asthma in Baranya County, Hungary, between 2003 and 2006].
abstract: BACKGROUND
  The prevalence of bronchial asthma, allergic rhinitis and atopic dermatitis (AD) in children has constantly and significantly increased worldwide in the past decades. Recent publications, however, reported a moderate decrease or levelling off in this parameter. The authors estimated the prevalence of bronchial asthma and asthmatic complaints among schoolchildren in Baranya county in the years 2003 and 2006 in order to register the possible changes.
  
  
  METHODS
  Both surveys were carried out by means of identical questionnaires which were consistent with the ISAAC Phase III. protocol. The data were collected in 16 primary schools (6 in a city, 10 in small settlements and villages) in February 2006. Finally 2404 questionnaires (1124 boys, 1280 girls) in two age groups, among 6-7 and 13-14-year-old children were processed and compared to the data derived from the survey done in 2003.
  
  
  RESULTS
  The prevalence of the "wheezing-ever" and "physician diagnosed asthma" did not change during the observation period (2006: 20.2% and 6.7%; 2003: 19.8% and 8.2%) but there was a significant increase in the frequency of "wheezing in the last 12 months" (2006: 9.6%; 2003: 6.8%). As expected, significantly higher prevalence rates were detected among boys and in the 6-7-year-old age group than among girls and in the 13-14-year-old age group in both surveys. There was no significant difference in the two surveys in the prevalence of bronchial asthma and asthmatic signs between children from a city and from small settlements.
  
  
  CONCLUSIONS
  During the observation period of three years there was a significant increase "wheezing in the last 12 months", but the prevalence of "wheezing-ever" as well as the "physician-diagnosed asthma" remained unchanged.
