ABSTRACT
OBJECTIVE:
To evaluate the relationship between socioeconomic status (SES) and the prevalence of asthma and related symptoms among Brazilian children.METHODS:
The International Study of Asthma and Allergies in Childhood (ISAAC) written questionnaire was applied to 23,457 six- to seven-year-old schoolchildren (SC) and 58,144 thirteen- to fourteen-year-old adolescents (AD) from 20 Brazilian cities. SES was evaluated by infant mortality index, poverty index, and average nominal income for people older than 10 years of age.RESULTS:
Current asthma ranged from 16.5% to 31.2% among SC and from 11.8% to 30.5% among AD and severe asthma from 2.9% to 8.5% (SC) and 2.6% to 9.1% (AD). Higher values were observed in Brazilian-Northern, -Northeastern and -Southeastern centers. No significant association between SES and prevalence of asthma and related symptoms was observed.CONCLUSIONS:
In Brazil, the prevalence of asthma and related symptoms is quite variable and independent of SES.
