The authors report the results of a survey undertaken in June 1993 con
cerning the incidence and consequences of: asthma in Marseilles second
ary schools. After census and randomised sampling of pupils and school
s, a questionnaire was sent to the parents of 362 2nd year (age around
13) children as well as to Head teachers, Physical Education and Spor
ts (PES) leachers and nurses of nine secondary schools. The, incidence
of asthma at the age of 13.5 could be estimated at 9.31 % (80.11 % re
sponse rate) with school absenteeism for illness five times greater in
the << asthmatic >> group (22 as against 4.5 days during the school y
ear). Attacks were usually rare and slight. Asthma was considered a mi
nor problem by the majority of staff of the nine schools despite the o
nset of 26 attacks in a year. Self-help appeared to be the key word re
garding sports activities. Only 30 % of PES teachers avoided exposing
asthmatic children to endurance. Nurses reported difficulty in obtaini
ng the treatments taken by pupils and generally did not have beta-2 mi
metics in the infirmary. This survey confirms the high incidence of as
thma in children and demonstrates the difficulties encountered in the
management of this disease in a school context.
