Prevalence of asthma in Latin America. Critical look at ISAAC and other studies

Abstract

Currently, the ISAAC (International Study of Asthma and Allergies in Childhood) project is a global approach to assess the prevalence of asthma and other allergies in different latitudes. One of the great advantages of this project is that it compares using the same methodology, the prevalence of asthma in more than 50 cities during the same period of time, nevertheless the reproducibility of these results when compared with other studies of prevalence in each region has not been evaluated. In this review we aim to compare the epidemiological data provided by the ISAAC against the data identified in some regional cohort studies and by means of a critical evaluation to highlight the main similarities and to analyze the differences between these epidemiological data.
