OBJECTIVE To describe the prevalence of asthma and physician-diagnosed asthma in Brazilian adolescents. METHODS Cross-sectional, national, school-based study with adolescents from 12 to 17 years old, participants in the Study of Cardiovascular Risks in Adolescents (ERICA). The study stratified the sample by region and grouped according to schools and classes with representativeness to the set of cities with more than 100,000 inhabitants of the Country, macro-regions, capitals, and Federal District. A questionnaire collected data through a self-filled in method. We calculated the prevalences and their confidence intervals of 95% (95%CI) according to sex, age group, type of school and skin color. RESULTS Between 2013 and 2014, 74,589 adolescents were evaluated, 55.3% of the female sex. The total prevalence of active asthma was of 13.1% (95%CI 12.1-13.9), being higher in girls (14.8%; 95%CI 13.7-16.0) when compared to boys (11.2%; 95%CI 10.3-12.2) in all geographical strata examined.

Background: Asthma is the most common chronic disease among adolescents. Objective: To determine the prevalence of asthma and asthma-related symptoms using the International Study of Asthma and Allergies in Childhood (ISAAC) protocol to evaluate adolescents in the city of Santa Maria, located in the state of Rio Grande do Sul, Brazil. Method: A cross-sectional study evaluating 3066 schoolchildren from 13 to 14 years of age, selected by random sampling, as indicated in the ISAAC protocol. Data were collected from March to June of 2003 using the standardized ISAAC questionnaire, which was completed by the adolescents in the classroom and under the supervision of the researchers. Results: A total of 3066 valid questionnaires (95.5%) were collected. Among the asthma-related symptoms evaluated, the following prevalences were determined: history of wheezing: 42.1%; wheezing within the last 12 months: 16.7%; four or more wheezing attacks within the last 12 months: 1.9%; sleep disturbance on one or more nights a week within the last 12 months: 3.8%; impaired speech within the last 12 months: 3.8%; history of asthma: 14.9%; wheezing after exercise within the last 12 months: 19%; dry cough at night within the last 12 months: 32.4%. Values were significantly higher among females. Conclusion: The prevalence of asthma-related symptoms among adolescents living in the city of Santa Maria was high, predominantly among the females. However, the rate was comparable to the international average and was lower than those observed in larger metropolitan areas in Brazil. These findings underscore the need for regional studies in order to better understand the prevalence of asthma in Brazil.
The prevalence of asthma and atopy in schoolchildren from Porto Alegre, Brazil, has plateaued
OBJECTIVE: A significant increase in the prevalence of asthma and atopy was observed in epidemiological studies conducted in 1980, 1989 and 1998, with schoolchildren of Porto Alegre. The present study aims to determine changes in the prevalence of symptoms of current and lifetime asthma and also to document the prevalence of atopy in schoolchildren from a region of Porto Alegre. METHODS: This was a cross-sectional study in which schoolchildren from 5th to 8th grade (10-18 years), from four schools located in the same geographic area were interviewed. The questionnaire covered symptoms suggestive of lifetime or current asthma (at some point in life or in the last twelve months, respectively). In addition, skin tests were performed in a subset of 241 schoolchildren. RESULTS: 964 students were interviewed from a total of 1195 registered. The prevalence of lifetime asthma symptoms was found to be 41.7%, symptoms of current asthma 14.9% and atopy 52.7%. Compared to previous studies, the prevalence of lifetime asthma and atopy has stabilized while the prevalence of current asthma fell from 22% to 14.9% (P < 0.001). CONCLUSIONS: In the last decade the prevalence of atopy and lifetime asthma has plateaued, while the prevalence of current asthma fell.
