“…The findings of this study agree with those of other national articles7 , 10 , 11 and the results of Hertz-Picciotto et al,25 who pointed out the role of this pollutant in hospitalizations for lower respiratory tract infections in preschool children in the Czech Republic. Karr et al,13 using conditional logistic regression, showed that exposure to PM 2.5 was associated with increased risk of hospitalization for childhood bronchiolitis (OR=1.09; 95%CI: 1.04–1.14).…”

“…Os achados deste estudo concordam com os de outros artigos nacionais7 , 10 , 11 e com os resultados de Hertz-Picciotto et al .,25 que apontaram o papel desse poluente nas internações por doenças do trato respiratório inferior em pré-escolares da República Checa. Karr et al .,13 com o uso da regressão logística condicional, mostraram que exposições ao PM 2.5 estiveram associadas ao aumento do risco para hospitalização por bronquiolite infantil (OR=1,09; IC95%: 1,04-1,14).…”

Objective:To estimate the association between exposure to fine particulate matter with an aerodynamic diameter <2.5 microns (PM2.5) and hospitalizations for pneumonia and asthma in children.Methods:An ecological study of time series was performed, with daily indicators of hospitalization for pneumonia and asthma in children up to 10 years of age, living in Taubaté (SP) and estimated concentrations of PM2.5, between August 2011 and July 2012. A generalized additive model of Poisson regression was used to estimate the relative risk, with lag zero up to five days after exposure; the single pollutant model was adjusted by the apparent temperature, as defined from the temperature and relative air humidity, seasonality and weekday.Results:The values of the relative risks for hospitalization for pneumonia and asthma were significant for lag 0 (RR=1.051, 95%CI; 1.016 to 1.088); lag 2 (RR=1.066, 95%CI: 1.023 to 1.113); lag 3 (RR=1.053, 95%CI: 1.015 to 1.092); lag 4 (RR=1.043, 95%CI: 1.004 to 1.088) and lag 5 (RR=1.061, 95%CI: 1.018 to 1.106). The increase of 5mcg/m3 in PM2.5 contributes to increase the relative risk for hospitalization from 20.3 to 38.4 percentage points; however, the reduction of 5µg/m3 in PM2.5 concentration results in 38 fewer hospital admissions.Conclusions:Exposure to PM2.5 was associated with hospitalizations for pneumonia and asthma in children younger than 10 years of age, showing the role of fine particulate matter in child health and providing subsidies for the implementation of preventive measures to decrease these outcomes.

“…Note that PM 2.5 concentrations ranged from 13 µg/ m 3 in the rainy season to 21 µg/m 3 in the dry season. 25 In our study, the concentrations estimated by the CATT-BRAMS were within the range of estimated values for Cuiabá, MT, and Piracicaba, SP. The increase in the concentration of PM 2.5 in São José do Rio Preto would imply an increase between 23 and 26% in the risk of hospitalization, and these increases are close to those found in Cuiaba in the dry season.…”

Objective: Given that respiratory diseases are a major cause of hospitalization in children, the objectives of this study are to estimate the role of exposure to fine particulate matter in hospitalizations due to pneumonia and a possible reduction in the number of these hospitalizations and costs. Method: An ecological time-series study was developed with data on hospitalization for pneumonia among children under 10 years of age living in São José do Rio Preto, state of São Paulo, using PM 2.5 concentrations estimated using a mathematical model. We used Poisson regression with a dependent variable (hospitalization) associated with PM 2.5 concentrations and adjusted for effective temperature, seasonality and day of the week, with estimates of reductions in the number of hospitalizations and costs. Results: 1,161 children were admitted to hospital between October 1 st , 2011, and September 30 th , 2013; the average concentration of PM 2.5 was 18.7 µg/m 3 (≈32 µg/m 3 of PM 10 ) and exposure to this pollutant was associated with hospitalization four and five days after exposure. Conclusion: A 10 µg/m 3 decrease in concentration would imply 256 less hospital admissions and savings of approximately R$ 220,000 in a medium-sized city.

“…These factors contribute to the advection of particles, because there is less deposition in August, and majority cases of biomass burning occurred during August and September (Filho et al, 2013). In August 2010 (Figure 4(c)), we observed many pixels with AOD values >2.0, with some pixels having values >4.0.…”
