Objective To investigate the effects of the main atmospheric pollutants on cardio-cerebrovascular diseases and provide basis for cardio-cerebrovascular diseases (CCDs) control and prevention.
Methods Data about CCDs incidence rate, main atmospheric pollutants concentrations, and meteorological data (temperature and humidity) were collected for descriptive analysis, time series analysis, and generalized linear model analysis to quantify the association of short-term exposure to ambient air pollutants with CCDs.
Results The levels of PM10 and NO2 were positively correlated to the incidence rate of CCDs. A 10-μg/m3 increment of PM10 or NO2 concentration was significantly correlated to an elevation in the incidence rate of CCDs of 0.88‰ (0.19‰-1.57‰) or 1.39‰ (0.06‰-2.71‰), while the same pattern was not found in SO2. A positive correlation was found between CCDs and humidity (P=0.000).
Conclusion These findings suggest that the current levels of air pollutants in Qingpu may affect residents' health and increase the risk of CCDs. Therefore, more stringent measures are required to control the air pollution and lower the air pollutant level.
