A spatio-temporal model for estimating the long-term effects
of air pollution on respiratory hospital admissions in Greater
London
It has long been known that air pollution is harmful to human health, as many epidemiological
studies have been conducted into its effects. Collectively, these studies have investigated
both the acute and chronic effects of pollution, with the latter typically based on
individual level cohort designs that can be expensive to implement. As a result of the
increasing availability of small-area statistics, ecological spatio-temporal study designs
are also being used, with which a key statistical problem is allowing for residual spatiotemporal
autocorrelation that remains after the covariate effects have been removed. We
present a new model for estimating the effects of air pollution on human health, which
allows for residual spatio-temporal autocorrelation, and a study into the long-term effects
of air pollution on human health in Greater London, England. The individual and joint
effects of different pollutants are explored, via the use of single pollutant models and multiple
pollutant indices.
