Abstract: Objective

To analyze the influence of atmospheric pollutant exposure in stroke hospitalization risk in Changchun City, Jilin University.

Methods

The stroke cases admitted at the First Hospital of Jilin University from October 1, 2018 to October 30, 2019 and the atmospheric measurement data of Changchun city were collected. A case-cross study was conducted for Logistic regression analysis on single pollutant and multi-pollutant models.The lag effect of each air pollutant on stroke hospitalization risk was analyzed with single pollutant model, and the best lag of each air pollutant was determined according to the maximum odds ratio (OR).Multi-pollutant model was used to analyze the influence of air pullutants in the stroke hospitalization risk.

Results

A total of 3 633 cases were included. A single pollutatant model determined that the atmospheric abnormality for stroke admission was the best in the late stage of stay 4 d before onset. Multivariate model analysis found that atmospheric particulate matter 2.5 (PM2.5),sulfur dioxide (SO2), carbon monoxide (CO), and ozone (O3) concentrations 4 d before the onset of illness could affect stroke admission risk. Every 10 μg?m-3 increase in PM2.5 concentration increased stroke admission risk by 3% [95% confidence interval(CI) (1.007, 1.054)]; every 10 μg?m-3 increase in SO2 concentration increased stroke admission risk by 22.6% [95%CI (1.165,1.291)]; every 10 mg?m-3 increase in CO concentration increased stroke admission risk by 14% [95%CI (1.101,1.180)]; every 10 μg?m-3 increase in O3 concentration increased stroke admission risk by 3.7% [95%CI (1.029,1.046)].

Conclusion

The impact of air pollutants on stroke admission risk has a lagging effect. The increase of concentrations of PM2.5, SO2, CO and O3 in the atmosphere of Changchun city can increase the risk of local stroke admission.
