Abstract
There are limited studies examining the association between PM2.5 exposure and incident cerebrovascular disease (CD) cases in China. In this study, daily counts of incident CD cases and daily PM2.5 concentrations were obtained in Yantai, Shandong Province, China from 2014 to 2019. We used acombination of the Poisson-distribution generalized linear model (GLM) and adistributed lag nonlinear model (DLNM) to examine the association of short-term exposure to ambient PM2.5 and incident cases of CD. The results revealed that for every 10μg/m3 increment of PM2.5 would increase the incident CD cases by 0.216% (RR:1.00216, 95%CI:1.0016-1.0028) at lag4. The stratified analysis demonstrated that the females and residents aged 65years or above presented higher short-term PM2.5-associated CD risks than the males and aged below 65years. Targeted prevention strategies should be adopted to reduce the PM2.5-related CD burden, especially for the susceptible population in China.
