Abstract

Abstract

Objective To explore the effect of PM_2.5 on the mortality of cardio-cerebrovascular disease in Suzhou, China. Methods The death data, air pollutant data and meteorological data from January 1, 2016 to December 31, 2017 in Suzhou were collected. The general additive Poisson regression model was used to analyse the association of exposure to PM_2.5 with the daily deaths due to cardio-cerebrovascular disease, and to calculate the relative risk (RR) and 95% confidence intervals (95%CI) for an interquartile range (IQR) increase in PM_2.5. Results The number of deaths from cardio-cerebrovascular disease was 30 200. On average, there were approximately 41 deaths per day. The daily median concentration of PM_2.5 was 37.13 μg/m³ and IQR was 30.75 μg/m³. The RR values of single-day death and average death from cardio-cerebrovascular disease were 1.017(1.001-1.034) and 1.055(1.019-1.093)with an IQR increase of PM_2.5 concentration, respectively. Stratified by gender and age, female and the elderly aged over 65 had higher risks of death from the cardio-cerebrovascular disease. Conclusion The elevated level of ambient PM_2.5 was positively associated with the increase of mortality of cardio-cerebrovascular disease.
