Summary

The project is to measure exposure to outdoor and indoor air pollutants in asthma patients in order to show a possible association between variation in pollutant exposure and the occurrence of exacerbations in these patients

Detailed description

Asthma is a chronic airway disease affecting between 6% and 7% of the French adult population. Asthma is responsible for nearly 1000 deaths each year in France. Air pollution (indoor and outdoor) is responsible for 7 million deaths each year according to the World Health Organization (WHO) assessment published in 2018, including 65,000 in France. Studies monitoring exposure to indoor air pollutants are few in number in asthmatic patients. Very little research has been devoted to continuous monitoring of indoor air quality in homes. Our hypothesis is that variation in exposure to indoor air pollutants, in relation to outdoor air, would have an impact on the occurrence of exacerbations in asthmatic patients.
