About the EISL

The International Study of Wheezing in Infants (Estudio Internacional de Sibilancias en Lactantes [EISL]) is an international cross-sectional multi-centre study designed to assess the prevalence, severity and other factors related to infant wheezing during the first year of life in Latin America and the Iberian Peninsula. This study started in 2005 and currently there are participating centres in Latin America and Europe.
The EISL study was developed to evaluate the prevalence and severity of recurrent wheezing during the first 12 months of life and the potential risk factors for wheezing and other respiratory diseases, such as pneumonia. The present study, like the ISAAC (International Study of Asthma and Allergies in Childhood), will use case-definitions and standardized methodology, thus improving the validity of comparisons and facilitating international collaboration.
 

Objectives of EISL Study

1. To know the prevalence, severity and risk factors of recurrent wheezing during the first year of life of infants living in different parts of Latin America and Europe, and to make comparisons within and between countries.
2. To evaluate at the individual level the hypotheses which have been suggested by the findings of past studies carried out in the first world.
3. To examine the relationship between recurrent wheezing and pneumonia in infants living in different areas of Latin America and Europe, and to perform comparisons within and between countries.
4. To obtain reference measurements for evaluating future trends in the prevalence and severity of this disease.
5. To generate a network between the participating centres for future studies and to offer a framework for additional investigation on etiological and patho-physiological factors.
