Scope

What is the exposure-response function (ERF) of ambient temperature on mortality in Europe measured as % difference in summer (April-September) mortality per degree (Max Apparent Temperature) above the heat threshold (95% confidence intervals).

Definition

Data

  • Following WP3.7-work and WP4.3-screening, DRF will be based on the PHEWE project, which investigated the acute health effects of weather in 15 European cities and provided both pooled estimates (Mediterranean region and North-Continental region) of the impact of heat on mortality (Michelozzi et al. 2007; Baccini et al. 2008). DRFs are based on a linear threshold model. Heat exposure is defined as follows: °C Daily maximum Apparent Temperature over threshold temperature, warm season (April-September).
  • DRF available for: mortality due to natural causes, CVD mortality and RESP morality.
  • Assumption: Threshold and the DRF differ for the Mediterranean region and the North-continental region; we therefore assume that the EU-27 can be divided into two larger regions with different DRF.
  • Assumption: Temperatures above thresholds will only occur in warm season (April-September)
  • Assumption: DRF for mortality due to natural causes can be applied to total mortality
