| Abstrakt: | Background: To assess the short-term impact of pollution on the respiratory death rate in the city of Saragossa throughout the 1991-1995 period and to pinpoint whether any differences exists in terms of age and time of the year. Methods: The relationship of daily concentrations of smog and SO2 to the daily deaths due to respiratory diseases (CIE-9 460-486) and chronic lung blockage disease and similar EPOC-EA (490-496) was analyzed using Poisson models in keeping with the EMECAM procedure. Possible differences in the impact on those below and over age 70 and according to the six-month period in question were researched. Relative risks (RR) and 95% confidence, intervals (CI95%) WERE CALCULATED FOR 10 micrograms/m3 rises in pollutant. Results: A relationship was found to exist between the respiratory and smog death rate (RR 1.028 CI95% 1.006-1051), the highest risk being during the six-months period of warm weather. For those individuals over age 70, the relationship remained the same throughout this six-month period and was negative for those individuals under age 70. The RR's for the death rate based on EPOC-EA were, overall, 1.038 (CI95% 1.002-1075) and of 1.068 (CI95%: 1.004-1.137) for the six-month period of warm weather. The SO2 pollution showed a positive relationship to the respiratory death rate for the warm period for all ages, RR 1.093 (CI95%: 1.006-1.187) and for those under age 70 (RR 1.240 CI95%: 1.028-1.496). The impact was not conclusive for the cases of pneumonia. Conclusions: Low levels of air pollution can have a significant impact on the respiratory death rate, especially among the elderly and during the six-month period of warm weather. |
