Résumé
"Objective. To analyze the short-term impact of air pollutionon daily mortality in the City of Zaragoza (Spain). Materialand methods. This ecologic study was conductedin Zaragoza, Spain, from 1991 to 1993. Poisson autoregressivemodels were constructed to assess the associationbetween air particulate matter and sulphur dioxide SO2 anddaily deaths. Four outcome variables were studied: overallmortality (excluding external deaths), mortality in subjectsover 69 years of age, mortality due to respiratory disease,and mortality due to cardiovascular disease. A sample sizewas not obtained. Data analysis was conducted using thestatistical software EGRET and SPSS. Results. SO2 levelswere significantly associated with cardiovascular deaths(RR=1.018 IC 95%: 1.001-1.036) and particulate matter levelswith respiratory deaths (RR=1.028 IC 95%: 1.006-1.051).During the warm season, a significant relationship was foundbetween particulate mater and cardiovascular deaths (RR=1.020 IC 95%: 1.001-1.040). Conclusions. Low levels of airpollution were found in Zaragoza, with considerable variationin the concentration of air pollutant concentrationsand daily respiratory and cardiovascular deaths, particularlyduring the warm season.
