Short term association between ozone and mortality: global two stage time series study in 406 locations in 20 countries.

ABSTRACT:

Objective

To assess short term mortality risks and excess mortality associated with exposure to ozone in several cities worldwide.

Design

Two stage time series analysis.

Setting

406 cities in 20 countries, with overlapping periods between 1985 and 2015, collected from the database of Multi-City Multi-Country Collaborative Research Network.

Population

Deaths for all causes or for external causes only registered in each city within the study period. MAIN OUTCOME MEASURES: Daily total mortality (all or non-external causes only).

Results

A total of 45 165 171 deaths were analysed in the 406 cities. On average, a 10 µg/m³ increase in ozone during the current and previous day was associated with an overall relative risk of mortality of 1.0018
