There is substantial evidence from epidemiological surveys that
asthma prevalence has increased significantly in the school age
population over the past 30 years.1-6 In children in one community, doctor diagnosed asthma increased from 4.1% in 1964 to
10.2% in 19891 and to 19.6% in 1994.3 In
part these results may reflect increased awareness of symptoms and
diagnostic transfer, although these effects are unlikely to explain the
magnitude of the changes.4 Increases in the prevalence of
bronchial hyperresponsiveness (BHR), such as induced falls in peak
expiratory flow on exercise5 or methacholine bronchial
challenge testing6 have also been reported, supporting a
true increase in the prevalence of asthma. It is also becoming apparent
that this increase is mainly in children from "low risk" families;
those with no strong family history of atopic disease.7 8
Assuming that the reported increase in asthma is real, are there
opportunities to reduce the prevalence and turn the clock
