Estimating the Risk of Death from Air Pollution

Assessment of Deaths Attributable to Air Pollution: Should We Use Risk Estimates based on Time Series or on Cohort Studies? ( 6 page pdf, N. Künzli, S. Medina, R. Kaiser, P. Quénel, F. Horak, Jr., and M. Studnicka, American Journal of Epidemiology, Vol. 153, No. 11, 2001)

Today’s review looks at an analysis of the two ways of estimating the risk of death from air pollution- as an event from immediate pre-death conditions over a short time (using time series) or as a cumulative result over a lifetime using cohort groups. The authors suggest that each risk estimate has value and each has strengths and weaknesses. The analysis could be useful in suggesting what and how often to monitor and how to use the data.
