Several evaluations of cumulative prevalence (c.p.) of childhood asthma (dyspnoea with wheeze) were made from 1970 to 1976 in all the 6 and 12-years old children living in Corsica. In the 6-years old children c.p. was: 1.56% (1970), 1.34% (1971) and 1.72% (1976). In the 12-years old children c.p. was 1.77% (1970) and 1.57% (1971).
A survey performed in young adult males (military recruits) showed that 14.1% had wheeze in the chest, 8.9% had attacks of dyspnoea at rest with wheeze in the chest and 6.2% had asthma.

A survey of 27 604 sujets aged mostly between 17 and 19 revealed that 33.5% of them had a regular nasal obstruction and that 13.6% repeated sneezing fits. Prevalence of nasal manifestations related to an allergy to graminaceae pollen was estimated at 5%. Besides there was a close relationship between the chronic nasal symptomatology and the smoking habits of the subjects concerned.
