short-term effects of ozone air pollution on ischaemic stroke occurrence: a case-crossover analysis from a 10-year population-based study in dijon, france

[Objective] to evaluate the monthly occurrence of air pollutants and acute stroke-Population of the Year-based study.
Methods: Daily stroke counts were obtained from the Dijon Stroke Register from March 1994 to December 2004.
Record everything first-
There was a stroke among Dijon residents (
150 residents)
Standard diagnostic criteria are used in France.
Concentration of pollutants (
SO2, CO, NO2, 03 and PM10)
Measure every hour. A bi-
Directional housing-
Cross-design is used to study the association between air contaminants and stroke episodes.
The conditional logistic regression model includes meteorological parameters (
Temperature, relative humidity)
Flu outbreak and holidays
Results: the authors collected 493 major artery blocks, 397 small artery blocks, and 530 heart artery blocks.
Cork attacks, 67 cases of unexplained attacks, 371 cases of short-term ischemia attacks, and 220 cases of bleeding attacks. For single-
Increased ozone exposure in pollutant models and 10 mg/m3 was observed only in men over 40-1-day lag, (OR 1. 133, 95% CI 1. 052 to 1. 220)and 0-day lag (OR 1. 058, 95% CI 0. 987 to 1. 134).
No significant association was found for bleeding stroke. In two-
In the pollutant model, after each other pollutant is included in the model, the effect of ozone is still significant, especially pm2. 5.
A significant association was observed between major artery ischemia stroke (
These results have yet to be confirmed by other studies.
