Bottom Line: The relative risks were RR = 1.008; 95%CI 1.001;1.016 for lag 1 and RR = 1.009; 95%CI 1.001;1.017 for lag 3.The increment of 10 μg/m3 in particulate matter less than 2.5 microns in diameter implies increase in relative risk of between 7.9 and 8.6 percentage points.In conclusion, exposure to particulate matter less than 2.5 microns in diameter was associated with hospitalization for respiratory disease in children.

ABSTRACT
The aim of this study was to estimate the association between exposure to particulate matter less than 2.5 microns in diameter and hospitalization for respiratory disease. It was an ecological time series study with daily indicators of hospitalization for respiratory diseases in children up to 10 years old, living in Piracicaba, SP, Southeastern Brazil, between August 1, 2011 and July 31, 2012. A generalized additive Poisson regression model was used. The relative risks were RR = 1.008; 95%CI 1.001;1.016 for lag 1 and RR = 1.009; 95%CI 1.001;1.017 for lag 3. The increment of 10 μg/m3 in particulate matter less than 2.5 microns in diameter implies increase in relative risk of between 7.9 and 8.6 percentage points. In conclusion, exposure to particulate matter less than 2.5 microns in diameter was associated with hospitalization for respiratory disease in children.

f01: Relative risk of respiratory disease in children under 10 and respective 95%confidence intervals for the pollutant PM2.5for eachlag . Piracicaba, SP, August 1, 2011 to July 31,2012.

Mentions: The relative risks and their respective 95% confidence intervals showed a positiveassociation between hospitalizations and PM2.5(RR = 1.008; 95%CI1.001;1.016 for lag 1 and RR = 1.009; 95%CI 1.001;1.017 for lag 3).The increase of 10 μg/m3of PM2.5meant an increase of between7.9 ( lag 1) and 8.6 ( lag 3) percentage points inthe relative risk (Figure).
