Impacts of climate variability on respiratory morbidity

To assess the effects of air pollution levels on respiratory morbidity among children from 2005 and 2008. Data were obtained from daily visits for respiratory diseases for children in health units in the Unified He- alth System (SUS) in the municipality of Campo Grande, MS, Brazil. Daily levels of ozone concentration were obtained from the Department of Physics, UFMS. Daily measurements of temperature and relative humidity were provided by the Agricultural Research Corporation-Embrapa Gado de Corte-MS. To assess the relationship between respiratory diseases and ozone concentration were carried out descriptive analysis of quantitative variables described by means of central tendency (mean, median) and dispersion (standard deviation) and coefficient of variation (CV) and later via modeling Generalized Linear Models (GLM) using the model of multiple Poisson regression. The results suggest that the surface ozone concentration promotes adverse effects on children's health even when pollutant levels below what is required by law.
