Effects Of Meteorological Factors On The Mortality Of Cardiovascular And Cerebrovascular Diseases Among Residents In Inner Mongolia

With the intensification of global warming,the influence of meteorological factors on human health has gradually increased,especially for chronic diseases represented by cardiovascular,cerebrovascular diseases,respiratory diseases and malignant tumors.Cardiovascular and cerebrovascular diseases,as the world’s largest death cause,have brought great disease burden to Chinese residents.Therefore,the relationship between meteorological factors and cardiovascular and cerebrovascular diseases has become a hot topic in statistics and environmental science.In this paper,descriptive statistical method and two inferential statistical methods are used to explore the influence of meteorological factors represented by temperature on the death of cardiovascular and cerebrovascular diseases in the death cause monitoring area of Inner Mongolia,so as to improve the prevention and control work in these areas.Firstly,the descriptive analysis method was used to summarize and analyze the death cause data of cardiovascular and cerebrovascular diseases in the death cause monitoring area of Inner Mongolia from 2013 to 2018,and to explore the overall characteristics and change trend of cardiovascular and cerebrovascular disease death in Inner Mongolia from the aspects of age distribution,gender distribution,urban and rural distribution and time distribution.The results show that the mortality rate of cardiovascular and cerebrovascular diseases in Inner Mongolia death cause monitoring area from 2013 to 2018 is 291.08/100,000,the mortality rate in rural areas is higher than that in urban areas,the mortality rate in men is higher than that in women,the mortality rate of the elderly is relatively large,and the mortality rate of cardiovascular and cerebrovascular diseases has obvious seasonal characteristics.Geographically,the mortality of cardiovascular and cerebrovascular diseases in Horqin Right Wing central banner is relatively higher than other areas.Secondly,in order to explore the short-term lag effect of different temperature levels on the death of cardiovascular and cerebrovascular diseases in four districts and counties of Inner Mongolia,Poisson generalized linear model combined with distributed lag non-linear models(DLNM)was used to analyze the exposure-lag-response relationship between temperature and death of cardiovascular and cerebrovascular diseases in different regions.The results showed that heat effect had different effects on the death risk of cardiovascular and cerebrovascular diseases in four regions.Qingshan district,in particular,reached the highest risk value at a lag of 1 day.Only Haibowan district has slightly cold effect.There is a high risk of cumulative lag thermal effect in Manzhouli city and Qingshan district.Thirdly,based on the monthly value as the measurement scale,assuming that the impact of meteorological factors on the death of cardiovascular and cerebrovascular diseases is linear,the random effect panel model is constructed after the panel unit root test.The results showed that the monthly mean of air temperature and relative humidity had a significant negative effect on the mortality of cardiovascular and cerebrovascular diseases,while the sunshine duration had a significant positive effect on the mortality of cardiovascular and cerebrovascular diseases.
