Prevalence of asthma, rhinitis, and eczema from ISAAC survey of schoolchildren in Central Taiwan.

Asthma is a common disease among schoolchildren in Taiwan. It is clearly a trend that the prevalence of asthma, rhinitis, and eczema has been increasing in developed countries such as Taiwan, but the data remain limited. This study is part of an effort to evaluate the epidemiology of asthma, rhinitis and eczema in Taiwan and to assess the prevalence and severity of those disorders among school age in central Taiwan.
