Has the prevalence of asthma increased in children? Evidence from a long term study in Israel.

Abstract

The significant rise in asthma and related respiratory conditions coupled with reduced PFT observed in this study suggest that the increase over time in the prevalence of asthma is a true increase in morbidity and not due to reporting bias. The increased prevalence of asthma could be observed in all the communities studied and does not seem to be connected with the operation of the power plant.
