title: [Air pollution and pediatric hospital admissions due to respiratory diseases in Cubatão, São Paulo State, Brazil, from 1997 to 2004].
abstract: The aim of this study was to evaluate the effects of air pollutants and their lag structures in relation to respiratory morbidity among children and adolescents in the city of Cubatão, São Paulo State, Brazil, from 1997 to 2004. An ecological time-series study was performed, analyzing respiratory hospital admissions of children and adolescents in National Health System hospitals in Cubatão. Generalized linear Poisson regression models were used to control for seasonality, temperature, humidity, and short-term trends. PM10 and ozone were significantly associated with respiratory hospital admissions. Among children, inter-quartile range increases in the PM10 7-day moving average (56.5µg/m³) and in the ozone 5-day moving average (46.7µg/m³) led to increases of 9.6% (95%CI: 3.0%-16.1%) and 2.4% (95%CI: 0.1%-4.7%) in respiratory hospital admissions, respectively. Efforts to reduce air pollutants need to be adopted to minimize the adverse effects on children and adolescents in Cubatão.
