“…8 The vast majority of studies in Brazil evaluating air pollution and respiratory diseases were developed in large urban centers, including São Paulo, Rio de Janeiro and Curitiba. [8][9][10][11][12] However, there are few studies on the effects of air pollution outside of major urban centers, especially in areas where there is biomass burning such as sugarcane straw. [13][14][15] Thus, the objective of this study was to estimate the association between exposure to air pollution and hospital admissions for pneumonia in children living in Araraquara, a medium-sized municipality in the state of São Paulo, in the period from January 2010 to November 2012.…”

Objective: The aim of this study was to estimate the association between exposure to air pollutants and hospitalization for pneumonia among children in a medium-sized city located in the sugar cane plantation region of São Paulo State. Methods: An ecological time-series study was conducted with daily data of hospitalization for pneumonia including children aged 10 years or younger living in Araraquara, state of São Paulo, from January 1 st , 2010, to November 30 th , 2012. To estimate the association between hospitalization due to pneumonia and particulate pollutants with aerodynamic diameter less than 10 µm, nitrogen dioxide and ozone, relative risks for hospitalization according to a generalized additive model of Poisson regression, with Lags of up to five days, were calculated. A percentage increase (PI) was obtained for relative risk (IRR -increase on relative risk) of hospitalization at each 10 μg/m 3 increment in each air pollutants adjusted for the remaining. Results: A total of 234 hospitalizations were recorded during these three years. There was a strong association between hospitalization and PM 10 and NO 2 . The PI in relative risk was 15% to PM 10 in Lag 0 and 7% points in Lag 1 for NO 2 . Conclusion: There was evidence of the action of air pollutants on hospitalization for pneumonia in a medium-sized city located in a region affected by air pollution from sugarcane burning and the data presented here provide subsidies for the implementation of public policies aiming to decrease this risk.

“…The association between air pollution and human health in the city of São Paulo, Brazil, has long been of public concern and the subject of several studies (Saldiva et al, 1994;Saldiva et al, 1995;Miraglia et al, 1997;Pereira et al, 1998;Braga et al, 1999;Lin et al, 1999 ). The main objective of the present investigation is to examine the relationship between air pollution and mortality, controlling for meteorological variables, based on daily death counts for people over 65 years old in São Paulo.…”

We study the effects of various air -pollution variables on the daily death counts for people over 65 years in São Paulo, Brazil, from 1991 to 1993, controlling for meteorological variables. We use a state space model where the air -pollution variables enter via the latent process, and the meteorological variables via the observation equation. The latent process represents the potential mortality due to air pollution, and is estimated by Kalman filter techniques. The effect of air pollution on mortality is found to be a function of the variation in the sulphur dioxide level for the previous 3 days, whereas the other air -pollution variables ( total suspended particulates, nitrogen dioxide, carbon monoxide, ozone ) are not significant when sulphur dioxide is in the equation. There are significant effects of humidity and up to lag 3 of temperature, and a significant seasonal variation.

“…13 There is strong evidence showing the association of air pollution and significant increase in the risk of death and chronic diseases in children, adverse pregnancy outcomes and severe illnesses. 4,12,15 The most prominent air pollutants associated to these outcomes are sulphur dioxide (SO 2 ), ozone (O 3 ) and particulate matter having an aerodynamic diameter of less than 10 mm (PM 10 ).…”

ObjectiveOf the effects of air pollution on children's health, increased pneumonia admission rate is one of the most important. The study aimed at estimating the association between pneumonia admissions and increased air pollutants. Methods An ecological time-series study was carried out in the municipality of São José dos Campos, Southeastern Brazil, in the years 2000 and 2001. Daily records of pneumonia admissions, air pollutants (SO 2 , O 3 , and PM 10 ) and weather conditions (temperature and humidity) were analyzed. The correlations between the study variables were estimated using Pearson's correlation. The associations between pneumonia and air pollutants were estimated using generalized additive Poisson regression models. The percentage increase (and their respective 95% CI) in pneumonia admission rate was estimated for the interquartile range of each air pollutant studied. ResultsThe three pollutants analyzed presented lagged effects on pneumonia admission rate, beginning at lag 3 or 4 and lasting for no more than two days. The 8-day cumulative effect estimate showed that an increase of 24.7 mg/m 3 in PM 10 concentration increased pneumonia admission rate in 9.8%. ConclusionsThe study corroborates that adverse health effects of air pollutants can be observed even in medium-sized cities. The magnitude of the effect was similar to that found in the city of São Paulo. Moreover, children are highly susceptible to air pollution exposure.
