[Asthma in France: a review of descriptive epidemiological data]

This article presents a review of the most recent data on descriptive epidemiology of asthma in France. The latest national surveys show a cumulative prevalence of asthma of more than 10% in children aged 10 years or more and a prevalence of current asthma from 6 to 7% in adults. In 2006, 1038 deaths from asthma were registered (64 deaths among people aged less than 45 years). After the peak observed in the 1980s, mortality from asthma has decreased. The decrease is also observed among children and young adults. According to data from the French discharge database (PMSI), there were 54 130 admissions for asthma (asthma as the principal diagnosis) in 2007. Between 1998 and 2007, the annual rate of admission for asthma decreased. However, no decreasing trend was observed in children and, in adults, admission rates seem to have been stable since 2004. The increase in the rate of admission for acute respiratory failure (ARF) associated with asthma (ARF as the principal diagnosis and asthma as an associated diagnosis) does not compensate for the decrease in the admission rate for asthma that was observed in adults. Data on emergency department visits show evidence of strong seasonal variations in asthma exacerbations.
