Association between Airborne Fine Particulate Matter and Residents' Cardiovascular Diseases, Ischemic Heart Disease and Cerebral Vascular Disease Mortality in Areas with Lighter Air Pollution in China.

ABSTRACT:

Background

China began to carry out fine particulate matter (PM_2.5) monitoring in 2013 and the amount of related research is low, especially in areas with lighter air pollution. This study aims to explore the association between PM_2.5 and cardiovascular disease (CVD), ischemic heart disease (IHD) and cerebral vascular disease (EVD) mortality in areas with lighter air pollution.

Methods

Data on resident mortality, air pollution and meteorology in Shenzhen during 2013?2015 were collected and analyzed using semi-parametric generalized additive models (GAM) with Poisson distribution of time series analysis.

Results

Six pollutants were measured at seven air quality monitoring sites, including PM_2.5, PM₁₀, SO?, NO?, CO and O?. The PM_2.5 daily average concentration was 35.0 ± 21.9 ?g/m³; the daily average concentration range was from 7.1 ?g/m³ to 137.1 ?g/m³. PM_2.5 concentration had significant effects on CVD, IHD and EVD mortality. While PM_2.5 concentration of lag5 and lag02 rose by 10 ?g/m³, the excess risk (ER) of CVD mortality were 1.50% (95% CI: 0.51?2.50%) and 2.09% (95% CI: 0.79?3.41%), respectively. While PM_2.5 concentration of lag2 and lag02 rose by 10 ?g/m³, the ER of IHD mortality were 2.87% (95% CI: 0.71?5.07%) and 3.86% (95% CI: 1.17?6.63%), respectively. While PM_2.5 concentration of lag4 and lag04 rose by 10 ?g/m³, the ER of EVD mortality were 2.09% (95% CI: 2.28?3.92%) and 3.08% (95% CI: 0.68?5.53%), respectively.

Conclusions

PM_2.5 increased CVD mortality. The government needs to strengthen the governance of air pollution in areas with a slight pollution.
