| Objective Using case crossover design to explore the association between ambient air pollution and the hospital emergency room visits for respiratory diseases (International Classification of Diseases, tenth vision ICD 10: J00 J99) in Beijing, China. Methods Data regarding the daily hospital emergency room visits' of the respiratory diseases (ICD 10: J00 J99)were obtained in 2004.01.01 2005.12.31, from the Peking University Third Hospital and data on relevant air pollution and meteorological factors from the local municipal environmental monitoring center and meteorology bureau of Beijing, respectively. Time stratified case crossover technique was used to evaluate their relationships. Results from the bi directional control sampling approach were compared with unidirectional approach. Results Using a unidirectional control sampling approach,the results obtained from a conditional logistic regression model (multi pollutant model) after adjusting for meteorological variables, showed that the ORs of the hospital emergency room visits for the respiratory diseases associated with each 10 μg/m3 increment of PM10, SO2, NO2 were 1.010(95%CI: 1.005 1.014), 1.010(95%CI: 1.001 1.018) ,0.996(95%CI:0.983 1.009) respectively.In the bi directional control sampling approach, the ORs were 1.002(95%CI:0.998 1.005)、 1.011 (95%CI:1.003 1.018)、 1.012(95%CI: 1.001 1.022). Conclusion Results from this study provided evidence that higher levels of ambient air pollutants increased the risk of hospital emergency room visits for respiratory diseases. |
