Abstract:
Objective To understand the acute effect of ambient air CO pollution on daily mortality of cerebrocardiovascular diseases among highly and long-term exposed residents of 65 years and over in Taiyuan,Shanxi,China.Methods The relationship of CO concentration and daily mortality of cerebrocardiovascular diseases among residents over 65 years old in Taiyuan(2003-2004) was analyzed by case-crossover design and conditional Logistic regression in SAS 9.0 Results The 48 h accumulated CO concentration had the most significant effect.As increment of CO average was 100 ?g/m~3,the corresponding OR of the effect on the total deaths of the cerebrocardiovascular diseases,the cardiac disease,the ischemic heart disease,myocardial infarction,cardiac failure,arrhythmia and stroke was 1.006,1.010,1.007,1.005,1.005,1.006 and 1.012 respectively.Under different air pollution conditions,the pollutant presented different effects on deaths of eerebrocardiovascular diseases.Conclusion The current CO pollution has caused a certain adverse effect on the cerebrocardiovascular mortality among residents of 65 years and over in Taiyuan city.More stringent measures should be taken to control the air pollution and decrease CO level,thus reduce the mortality of cerebrocardiovascular diseases.
