Adult Asthma Risk Factors

(Page 2)

There are significant differences among nations. In a major study of 22 nations published in 2001, the countries with the highest asthma rates were Britain, Ireland, Australia, New Zealand, and the U.S. (According to another study, asthma rates are also significantly higher in Canadian adults than they are in comparable European groups.) Low rates were reported in Iceland, Norway, Spain, Germany, Italy, Algeria, India, and Eastern European nations. The reasons for these variations are still unknown.
