[Association between ambient PM10/PM2.5 levels and population mortality of circulatory diseases: a case-crossover study in Beijing].

摘要: OBJECTIVE To explore the association between levels of ambient particulate matters (PM10 and PM2.5) population mortality circulatory diseases (ICD10: I00~I99) in Beijing. METHODS The daily data PM2.5 were monitored by research team Peking University from Jan. 1, 2007 to Dec. 31, 2008, corresponding meteorological other air quality (PM10, SO2 NO2) collected National Meteorological Information Center (NMIC) China Beijing Environmental Monitoring Center. death for local center Disease Control Prevention Haidian District symmetric bidirectional case-crossover design conditional logistic regression model used analysis. cases stratified gender, age seasons. lagged effect was analyzed related confounders factors pollutants adjusted. RESULTS For a 10 μg/m(3) increase concentration PM2.5, diseases, cardiovascular cerebrovascular 0.78% (95% CI: 0.07% 1.49%), 0.85% -0.28% 1.99%), 0.75% -0.17% 1.68%), respectively, PM10, 0.36% -0.07% 0.78%), 0.63% -0.02% 1.28%), 0.33% -0.26% 0.92%),respectively. significant positive associations observed statistically (P<0.05). PMs stronger "warm season (April September)" than "cool (October next March)" CONCLUSION elevated PM10 positively associated with is warm season, adverse greater that PM10.
