RESUMEN
A cross-sectional population-based study was conducted in Lages, Santa Catarina State, Brazil, in order to estimate the prevalence of symptoms of chronic bronchitis, breathlessness, and wheezing and associated factors in a sample of adults 20 to 59 years of age (n = 2,051). The study employed a cluster sample design and Poisson regression analyses. Prevalence rates for chronic bronchitis, breathlessness, and wheezing were 5%, 35.7%, and 20.2%, respectively. The adjusted analysis showed chronic bronchitis associated with low schooling, smoking, and hospital admissions due to respiratory illness during childhood. Breathlessness was associated with female gender, low schooling and family income, non-white race, hospital admissions due to respiratory illness during childhood, smoking, and occupational exposure to dust. Wheezing was associated with female gender, low schooling and family income, non-white race, hospital admissions due to respiratory illness during childhood, smoking, and occupational exposure to dust. Public health planners should consider climatic factors and work activities when developing activities to prevent respiratory diseases.

Realizou-se estudo transversal de base populacional em Lages, Santa Catarina, Brasil, para estimar a prevalência de sintomas de bronquite crônica, falta de ar e chiado no peito e os fatores associados em adultos de 20-59 anos de idade (n = 2.051). Processo de amostragem através de conglomerados e análise de regressão de Poisson foram realizados. As prevalências de bronquite crônica, falta de ar e chiado no peito foram de 5 por cento, 35,7 por cento e 20,2 por cento, respectivamente. Análises ajustadas mostraram presença de bronquite crônica associada à baixa escolaridade, fumar dez ou mais pacotes de cigarros ao ano e internação por problemas de pulmão na infância. Falta de ar associou-se ao sexo feminino, baixa escolaridade e renda familiar, pardos e amarelos, história de internação por problemas de pulmão na infância, ser fumante e trabalhar com poeira ou pó. Presença de chiado no peito associou-se ao sexo feminino, baixa escolaridade e renda familiar, pardos e pretos, história de internação por problemas de pulmão na infância, ser fumante e trabalhar com poeira ou pó. Particularidades do clima e das atividades laborais devem ser consideradas no planejamento das ações em saúde.
