Abstract:
Objective To analyze the temperature modification effect on emergency room visits for circulatory and respiratory diseases caused by air pollution,in Beijing,Methods Data on both circulatory and respiratory diseases in 2010 and 2011 were collected,Both meteorological and air pollutants related data were obtained from the National Scientific Data Sharing Platform for Population and Health.By using the stratified time-series models,we analyzed the effects of air pollution on emergency room visits for circulatory and respiratory diseases under different temperature zones,from 2010 to 2011,in Beijing.Results Low temperature (daily average temperature ＜-4.9 ℃) seemed to have obviously enhanced the effect of air pollution index (API) on emergency room visits for circulatory diseases,Under 10 units of API,the relative risks and confidence interval appeared as 1.067 (1.054-1.080).However,high (daily average temperature between 24.4 ℃ and 28.5 ℃) and extra-high temperature (daily average temperature ＞28.5 ℃) could enhance the effect of API on emergency room visits for respiratory diseases,Under 10 units of API,the relative risks and confidence interval were 1.021 (1.015-1.028) and 1.006 (1.003-1.008),respectively.Conclusion Temperature seemed to have modified the association between air pollution and both circulatory and respiratory diseases.
