Resumo: | OBJECTIVE: To assess the relationship between air pollution and acute respiratory disorders in children. METHODS: A time series ecological study was carried out in three public health posts in a region of the city of Rio de Janeiro (Southeastern Brazil), between April 2002 and March 2003. Data for PM10, SO2, NO2, CO and O3 were analyzed daily and as closure variables, a total of 45,595 emergency pediatric consultations for respiratory symptoms or specifically for disorders in the upper and lower airways. To control for confounders, other variables were included in the model including those relating to weather, seasonality, temperature, relative air humidity, rain volume, respiratory infections and the calendar effects (such as holidays and weekends). A Poisson regression was applied using generalized counting models to estimate the effects of pollutants and confusing factors. RESULTS: Only O3 had a positive and statistically significant effect, both among emergency consultations for respiratory problems and consultations for symptoms relating to the lower airways. Effect and exposure occurred on the same day (lag 0). A significant negative association was found with CO and pediatric consultations for respiratory complaints. Other air pollutants were not found to have a significant effect. CONCLUSIONS: There were found associations between outdoor air pollution and the number of emergency pediatric consultations for respiratory problems in the studied area, in spite of the fact that the levels of all pollutants monitored during the study period were below recommended levels. |

OBJETIVO: Avaliar a relação entre poluição do ar e efeitos respiratórios agudos em crianças. MÉTODOS: Foi realizado um estudo ecológico de séries temporais em três unidades públicas de saúde do bairro de Jacarepaguá, município do Rio de Janeiro, entre abril de 2002 e março de 2003. Foram analisados dados diários de PM10, SO2, NO2, CO e O3, e como variáveis de desfecho 45.595 atendimentos pediátricos de emergência por sintomas respiratórios ou específicos por transtornos nas vias aéreas superiores e nas vias aéreas inferiores. Foram incluídas no modelo para controle de confundimento as variáveis referentes à tendência temporal, sazonalidade, temperatura, umidade relativa do ar, precipitação de chuva, infecções respiratórias e os efeitos do calendário (como feriados e finais de semana). Foi empregada a regressão de Poisson via modelos aditivos generalizados para estimar os efeitos dos poluentes e dos fatores de confusão. RESULTADOS: Somente o O3 apresentou resultado positivo e estatisticamente significativo, tanto com todos os atendimentos de emergência por queixas respiratórias como com os atendimentos motivados por sintomas nas vias aéreas inferiores. O efeito foi no mesmo dia da exposição (lag 0). Associação significativa e de sentido inverso ocorreu com o CO e os atendimentos pediátricos por queixas respiratórias. Não se observou resultado significativo com os demais poluentes atmosféricos. CONCLUSÕES: Foram encontradas associações entre indicadores de poluição atmosférica e o número de atendimentos pediátricos de emergência por motivos respiratórios em Jacarepaguá, apesar de os níveis de todos os poluentes monitorados permanecessem abaixo dos limites recomendados durante todo o período de estudos.
