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. null Belize China Germany Italy France Japan Korea, Republic of Taiwan, Province of China Russian Federation Spain United Kingdom United States Individuals General population Male Female Child (6 to 12 years) primary school children - between 8 and 13 years old Clinical data Participant-reported health data Biological data Paraclinical data (non-biological) : Anthropometry Health event/morbidity One-time cross-sectional study Other Population database for statistical purposes [1000-10000[ individuals Physical/biological measurements (blood pressure, weight, biochemistry, imaging, etc.) Observational Study Observational Study Monde/World: 721 601 France: 7 432 Completed study Restricted access Contact the principal investigator Access on specific project only
