![]() ![]() The findings call for future investigation to examine the factors that might be working together with or against ozone pollution when health effects are concerned. The spatial dependency of disease prevalence is related to both the spatial patterns of pollution and those of confounding factors. The spatial variation of the relationship between ozone pollution and childhood respiratory disease prevalence indicates health effects of confounding or intervening factors. Moreover, spatial regression analysis suggests the presence of spatial dependence of the prevalence of childhood respiratory diseases. With the guidance from GWR results, the association between ozone pollution and childhood respiratory disease prevalence is proved to be significant in three sub-regions. However, geographically weighted regression (GWR) analysis reveals spatially varied adverse health effect. No significant global relationship exists between ozone pollution and prevalence of childhood respiratory diseases. The study period is June to September of 2001. This paper reports on the investigation of the spatial patterns and variations of adverse health effects of ozone pollution on childhood respiratory diseases in Houston, Texas. ![]()
