To establish a global map of the prevalence of childhood allergic diseases and to determine the risk factors for these diseases by comparing contrasting population groups based on a particularly strong or weak prevalence.

The ISAAC study consists of three phases:
The objective of Phase I is to assess the prevalence of asthma, allergic rhinitis and eczema by using a simple questionnaire and possible video questionnaire (for asthma), in representative samples of children from two age groups: 13-14 years old (obligatory for all centres) and 6-7 years old (optional).
Phase II aims to identify the risk factors and treatment procedures for allergic diseases through a more detailed study of selected population groups with relatively high or low prevalence rates suggested during Phase I.
Phase III aims to assess the trends in allergy prevalence.
As such, the Phase I protocol will be repeated in areas that participated in this phase.
