Previous issue date: 2014-11-10 / Background: Many developing countries have a high prevalence of asthma. However, the burden of disease has been scarcely reported from non-affluent populations. Aims: To assess the impact of the disease in Brazilian children with asthma from a large capital city.
Methods: We selected inner-city children with asthma and healthy controls from public schools, between eight and 16 years of age, from a capital city of southern Brazil. The study was divided into three phases, with questionnaires (asthma prevalence, quality of life, knowledge and impact of disease) applied, with assessment of lung function, nutritional status and allergic sensitization.
Results: From 2,500 children selected, with male gender of 1,211 (48.4%) and mean age of 11.42?2.32 years, 511 (20.4%) were diagnosed with asthma. The disease was not controlled in nearly half of the children with asthma, with a 7.5% of hospitalization rate in the last year. The majority of patients presented a history of dyspnea, exercise limitation or sleep disturbance because of asthma symptoms in the last 12 months, with high school absenteeism. Many patients required oral steroids in the previous year, and only 34% had a prescription of rescue medication, with 55% of passive smoking. Despite the free asthma medication access in Brazil since 2012, less than half of patients were using preventive treatment. Many parents assume that are not adherent to treatment and believe that rescue medication and exercise may be harmful.
Conclusions: We have shown that the burden of asthma in children from southern Brazil is substantial, and this may reflect the scenario of many non-affluent populations worldwide. New international guidelines more focused in developing countries with pragmatic approaches should be a priority for discussion and implementation. / Introdu??o: muitos pa?ses em desenvolvimento t?m uma elevada preval?ncia de asma. No entanto, o impacto da doen?a tem sido pouco relatado a partir de popula??es economicamente menos favorecidas.
Objetivo: avaliar o impacto da asma em crian?as brasileiras a partir de uma grande capital. M?todos: foram selecionadas crian?as com asma e controles saud?veis, de escolas p?blicas, entre oito e 16 anos de idade, de uma capital do sul do Brasil. O estudo foi dividido em tr?s fases, com question?rios (preval?ncia de asma, qualidade de vida, o conhecimento e o impacto da doen?a), aplicada, com a avalia??o da fun??o pulmonar, estado nutricional e sensibiliza??o al?rgica. Resultados: de 2.500 crian?as selecionadas, com o g?nero masculino de 1.211 (48,4%) e idade de 11,42?2,32 anos, 511 (20,4%), foram diagnosticadas com asma. A doen?a n?o estava controlada em cerca de metade das crian?as com asma, com 7,5% de taxa de hospitaliza??o no ?ltimo ano. A maioria dos pacientes apresentavam hist?ria de dispneia, limita??o ao exerc?cio ou dist?rbio do sono por causa de sintomas de asma nos ?ltimos 12 meses, com elevado absentismo. Muitos pacientes necessitaram de esteroides orais, nos doze meses, e apenas 34% tiveram prescri??o de medica??o de resgate, com 55% de tabagismo passivo. Apesar do acesso gratuito ? medica??o para a asma no Brasil desde 2012, menos da metade dos pacientes faziam uso de tratamento preventivo. Muitos pais assumem que n?o s?o aderentes ao tratamento e acreditam que a medica??o de resgate e exerc?cio pode ser prejudicial.
Conclus?es: mostramos no estudo que o ?nus da asma em crian?as do sul do Brasil ? substancial, e isso pode refletir o cen?rio de muitas popula??es economicamente menos favorecidas, em todo o mundo. Novas diretrizes internacionais mais focadas nos pa?ses em desenvolvimento com abordagens pragm?ticas deve ser uma prioridade para a discuss?o e implementa??o.
