Introduction:
Few data on regional variations in asthma prevalence are available in France.
Methods:
The study was carried out during the academic year 2005-2006 in a random sample of around 20,000 children in the last year of nursery school. The lifetime prevalence of asthma and the preceding year prevalences of asthma-like symptoms and treatment for wheezing or asthma attacks were estimated by region.
Results:
Overall, the lifetime prevalence of asthma was 9.8 % and the past-year prevalence of wheezing was 10.7 %. An increasing trend in prevalence was observed from Eastern to Western France and in overseas territories. The regional variations in past-year prevalence of wheezing remained when adjusting for gender, family structure and the number of siblings. Among children who had wheezed or received a treatment in the past year, 42 % had experienced frequent or severe symptoms.
Conclusion:
Large regional variations in asthma prevalence among young children in France exist.

Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
