Background: Variations in the prevalence of respiratory symptoms according to geo-climatic factors could provide important clues to the knowledge of the aetiology of asthma. Methods: Geo-climatic variations in the prevalence of current asthma, allergic rhinitis and chronic cough, and phlegm were assessed on a random sample of 18 873 subjects (response rate ¼ 72.7%)from different climatic regions of Italy. An ecological analysis, supported by robust statistical methods, was employed to investigate potential trends. Results: The prevalence of all symptoms was significantly heterogeneous throughout the peninsula. Only asthma-like symptoms showed a north–south trend: the prevalence increased at a decreasing latitude [odds ratio (OR)varie s from 0.92 to 0.96, P < 0.05], at a decreasing distance from the sea (OR: 0.90–0.93 for 30 km distance, P < 0.05), at higher annual mean temperatures (OR: 1.11–1.14, P < 0.05)and at smaller annual temperature ranges (OR: 0.94–0.95, P < 0.05). Of the geo-climatic variables considered, temperature range had the greatest influence on most asthma-like symptoms. No association was found between geo-climatic variables and allergic rhinitis or chronic cough and phlegm. Conclusions: Asthma prevalence seems to be significantly affected by climate as asthma-like symptoms were more common in central-southern Italy, with a Mediterranean climate, than in areas with a continental climate (northern Italy).
