Spatiotemporal analysis for the effect of ambient particulate matter on cause-specific respiratory mortality in Beijing, China.

摘要: This study explored the association between particulate matter with an aerodynamic diameter of less than 10 μm (PM10) and cause-specific respiratory mortality. We used ordinary kriging method to estimate spatial characteristics ambient PM10 at 1-km × 1-km resolution across Beijing during 2008-2009 subsequently fit exposure-response relationship estimated mortality due total disease, chronic lower obstructive pulmonary disease (COPD), pneumonia street or township area levels using generalized additive mixed model (GAMM). also examined effects age, gender, season in stratified analysis. The on were strongest lag0-5 except for pneumonia, inter-quantile range increase was associated 8.04 % (95 % CI 4.00, 12.63) a 6.63 % 1.65, 11.86) 5.68 % 0.54, 11.09) COPD, respectively. Higher risks exposure observed females elderly individuals. Seasonal stratification analysis showed that stronger spring autumn. While effect winter statistically significant (15.54 %, 95 % 5.64, 26.35) greatest among seasons. GAMM evaluated associations concentration PM10. There levels. high-resolution could better capture Gender, acted as modifiers
