【 摘 要 】

Objective: To evaluate the relationship between air pollution and acute respiratory disorders in children. Methods: An ecological study of time series conducted in public health units in the city of Campo Grande-MS, Brazil, from January 1, 2004 to December 31, 2007. Dailydata of O3 (ozone) were analyzed and, as outcome variables, 16,981 emergency pediatric consultations for respiratory symptoms; including in control model the variables related to time trend; seasonality; minimum, maximum and average temperature; relative humidity;rainfall and respiratory infections. We determined the Pearson correlation coefficient of respiratory diseases in relation to climatic parameters for the years 2004-2007. Results: Only O3 had a positive and statistically significant association, both with all emergency care attendances for respiratory complaints, as with these due to symptoms in lower airways. The daily average concentrations of O3 did not exceed the recommended daily limits. Conclusion: We found associations between air pollution and the number of emergencypediatric consultations for respiratory causes in Campo Grande, although the levels of monitored pollutant ozone remained below recommended levels throughout the study period.
