Résumé :

[BDSP. Notice produite par INIST-CNRS DoR0x7FJ. Diffusion soumise à autorisation]. Numerous epidemiological studies have shown associations between increases in outdoor air pollution and all-cause mortality as well as cardiovascular and respiratory related mortality. The majority of studies has used the routine monitoring network and thus has not been able to characterize the small-scale variation in daily averages and peak concentrations within urban settings. To address possible short term impact on mortally by air pollution we used a time-stratified case-crossover design to estimate associations of traffic-related air pollution and wood burning and daily mortality during a period of 10 years among residents above 50 years of age in Oslo, Norway. A dispersion model was used to assess short-term air pollution for daily (24-h) averages and peak concentrations of nitrogen dioxide (NO2) from exhaust and particulate matter with a diameter of 2.5 mum or less (PM2.5) from exhaust and wood-burning at residential neighbourhood level for each individual. We found an overall increased risk from exposure at the lag of 0-5 days before the day of death for both pollutants. The excess risk was highest for PM2.5 with a 2.8% (95% confidence interval : 1.2-4.4) increase per 10 mug per cubic meter change in daily exposure. Short-term traffic-related air pollution was associated with increased risk for mortality among individuals above 50 years of age, especially for circulatory outcomes.
