ACHE, Brasília Itália C. S.; KAHAN, Fabiane  e  FITERMAN, Jussara. Prevalence of asthma symptoms and treatment of children and adolescents from 2 to 14 years of age in Porto Alegre, Rio Grande do Sul, Brazil. J. bras. pneumol. [online]. 2005, vol.31, n.2, pp.103-110. ISSN 1806-3713.  https://doi.org/10.1590/S1806-37132005000200004.

BACKGROUND: In recent decades, the prevalence of asthma has increased. OBJECTIVES: To determine the prevalence of asthma symptoms in children and adolescents from 2 to 14 years of age living in Porto Alegre (in the state of Rio Grande do Sul, Brazil) and to determine any potential correlations with socioeconomic profile, treatment and smoking in the home. METHODS: A transversal study based on interviews of all families seeking medical attention in June of 2000. RESULTS: The prevalence of asthma symptoms was 49.5%. In 66.8% of families, total income was less than four times the minimum wage, and in more than 50% of homes, the parents had had less than five years of schooling. In 98.5%, prophylactic asthma treatment was not used. In the 174 families studied, 38.7% of mothers and 43.7% of fathers were smokers (32.7% overall). Correlations were found between the following variables: exposure to smoking in the home and number of asthma attacks in the last year (p = 0.02; RR = 2.9; CI: 1.1 - 4.5); maternal level of education and number of attacks in the last year (p = 0.03; RR = 2.03; CI: 1.01 -4.19); close living quarters and number of attacks in the last year among children exposed to second-hand smoke (p = 0.04; RR = 2.7; CI: 1.4 - 5.1); hospitalization and number of attacks in the last year (p = 0.004; RR = 1.46; CI: 1.15 -1.86); hospitalization and close living quarters (p = 0.03; RR = 1.47; CI: 1.15 - 1.86). In children below the age of five, there was correlation between maternal smoking and number of attacks in the last year (p = 0.03; RR = 1.79; CI: 1.04 -3.08). CONCLUSION: The prevalence of asthma symptoms was high. The community studied has limited socioeconomic resources, and there is therefore a lack of adequate treatment for asthma. Our results demonstrate the need for prioritized, standardized treatment programs that would give healthcare workers access to the appropriate materials and means of evaluation necessary for asthma control.
