Peretti I., Baldacci S., Della Maggiore R., Martini F., Nuvolone D., Stortini A. M., Viegi G. Uso di tecnologie GIS per l'analisi dell'associazione tra aerosol marino e prevalenza di asma in un campione di popolazione adulta di Livorno. In: VII Congresso Nazionale della Pneumologia (Firenze, 4-7 Ottobre 2006).
In this epidemiological survey a general population sample of Livorno was analysed to study the relationship between living near the sea and health status. In fact exposure to marine aerosol is considered to be a potential risk of respiratory diseases, as pollutants accumulated in the surface micro-layer are conveyed to the atmosphere. By means of GIS technology subjects participating to the survey were geocoded with reference to their home addresses, then they were classified considering zones homogeneous by distance from the coastline. In a second classification we also considered distance from the main industrial pollution sources. Bivariate and multivariate analyses were performed to compare the prevalence of asthma and asthma-like symptoms between exposed and non exposed people. Exposure to marine aerosol resulted associated with asthma, whilst exposure to industrial pollution is associated with bronchitic symptoms. GIS provides added value to environmental epidemiology research.
