Abstract

OBJECTIVE: To evaluate the characteristics of users of inhalers and the prevalence of inhaler use among adolescents and adults with self-reported physician-diagnosed asthma, bronchitis, or emphysema. METHODS: A population-based study conducted in the city of Pelotas, Brazil, involving 3,670 subjects ≥ 10 years of age, evaluated with a questionnaire. RESULTS: Approximately 10% of the sample reported at least one of the respiratory diseases studied. Among those individuals, 59% reported respiratory symptoms in the last year, and, of those, only half reported using inhalers. The use of inhalers differed significantly by socioeconomic status (39% and 61% for the lowest and the highest, respectively, p = 0.01). The frequency of inhaler use did not differ by gender or age. Among the individuals reporting emphysema and inhaler use, the use of the bronchodilator-corticosteroid combination was more common than was that of a bronchodilator alone. Only among the individuals reporting physician-diagnosed asthma and current symptoms was the proportion of inhaler users higher than 50%. CONCLUSIONS: In our sample, inhalers were underutilized, and the type of medication used by the individuals who reported emphysema does not seem to be in accordance with the consensus recommendations.OBJETIVO: Avaliar as características dos usuários de dispositivos inalatórios e a prevalência de uso desses em adolescentes e adultos com diagnóstico médico autorreferido de asma, bronquite ou enfisema. MÉTODOS: Estudo de base populacional realizado em Pelotas, RS, incluindo 3.670 indivíduos com idade ≥ 10 anos, avaliados com um questionário. RESULTADOS: Aproximadamente 10% da amostra referiram pelo menos uma das doenças respiratórias investigadas. Entre esses, 59% apresentaram sintomas respiratórios no último ano, e, desses, apenas metade usou inaladores. O uso de inaladores diferiu significativamente de acordo com o nível socioeconômico (39% e 61% entre mais pobres e mais ricos, respectivamente; p = 0,01). Não houve diferença na frequência de uso de inaladores por sexo ou idade. Entre indivíduos com enfisema, o uso da combinação broncodilatador + corticoide inalatório foi mais frequente que o uso isolado de broncodilatador. Somente entre os indivíduos que referiram diagnóstico médico de asma e sintomas atuais, a proporção de uso de inaladores foi maior que 50%. CONCLUSÕES: Em nossa amostra, os inaladores foram subutilizados, e o tipo de medicamento usado por aqueles que referiram enfisema parece não estar de acordo com o preconizado em consensos sobre essa doença.
