Resumo Neste estudo, foram observados niveis de concentracoes de poluentes atmosfericos da cidade de Curitiba, no periodo de novembro de 2003 a junho de 2008, da estacao automatica de monitoramento da praca Ouvidor Pardinho. O objetivo foi desenvolver uma metodologia de modelagem estatistica que explique o numero de notificacoes de doencas respiratorias registradas em idosos (acima de 60 anos) e criancas (abaixo de 5 anos). Alem das concentracoes de poluentes, algumas variaveis climaticas foram analisadas. Apos estudo de diversas metodologias estatisticas, considerou-se mais adequado o ajuste de Modelos Aditivos Generalizados para Locacao, Escala e Forma. Os modelos ajustados apresentaram resultados satisfatorios e consideraram como variaveis significativas as particulas inalaveis e a temperatura. Alem disso, verificou-se que existe reducao proporcional do numero de notificacoes de doencas respiratorias no periodo observado, em consequencia da reducao dos niveis de concentracao de particulas inalaveis no municipio de Curitiba. Os resultados encontrados podem ter sido influenciados pelas campanhas de vacinacao de idosos, pela utilizacao de motores menos poluentes no transporte coletivo, pelo aumento da producao de carros “flex” e tambem pela grande cobertura vegetal existente no municipio, responsavel pelos mais altos indices de area verde por habitante entre os grandes centros urbanos do Brasil. Abstract Relation between respiratory diseases and air pollution and climatic variables, in Curitiba, Parana, Brazil. In this research, concentration levels of atmospheric pollutants were observed between November 2003 and June 2008 from an automated monitoring station located at Ouvidor Pardinho Square, City of Curitiba. It aimed to develop a methodology of statistical model in order to explain the number of notifications of respiratory diseases registered in the elderly (above the age of 60 years) and children (below the age of 5 years). Apart from the concentration of pollutants, climatic variables were also analyzed. After study of several statistical methodologies, it was considered that the most adequate was an adjustment of the Generalized Additive Models for Location, Scale and Shape. The adjusted models presented satisfactory results and considered as significant variables the particulate matter and temperature. It was also observed a proportional reduction in the number of notifications of respiratory diseases within the observed period as a consequence of the concentration level reduction of the particulate matter in the city. These results may have been influenced by vaccination campaigns involving the elderly, by use of less polluting engines in the public transportation system, by an increase in production of “flex”- type cars and also by the large vegetation coverage in the city, which is responsible for one of the highest indexes of green area per inhabitant amongst the large urban centers in Brazil. Keywords: Generalized linear models; pollutants; particulate matter; GAMLSS.
