目的探讨脑卒中与其他疾病(心肌梗死、恶性肿瘤、传染病等)的空间依从关系,分析其是否存在共同的地理危险因子。方法收集2011~2014年沂源县脑卒中及其他疾病的发病数据、全死因死亡数据及人口学数据,应用地理加权回归(GWR)模型定量分析各因素与脑卒中的空间依从关系。结果 (1)除北部个别区域的心肌梗死发病密度与脑卒中发病呈负相关关系外,沂源县的心肌梗死与脑卒中呈正相关协同变化关系,且这种协同变化由西向东逐渐减弱;(2)恶性肿瘤与脑卒中呈正相关协同变化关系,且这种协同变化关系由北向南逐渐减弱;(3)除西部个别区域的传染病与脑卒中呈负相关关系外,沂源县传染病与脑卒中呈正相关协同变化关系,这种协同变化关系在中部大于西部和东部,且呈由北向南的递减趋势。结论脑卒中与心肌梗死、恶性肿瘤及传染病之间呈现空间协同变化关系,提示可能存在特定的共同地理社会因素。
Objective To explore the spatial dependence of stroke and other diseases (myocardial infarction, malignant tumor, infectious disease, etc.) and to analyze whether there is a common geographical risk factor. Methods The data of stroke and other diseases in Yiyuan County from 2011 to 2014 were collected, and the data of all-cause death and demographic data were collected. The geo-weighted regression (GWR) model was used to quantitatively analyze the spatial dependence of various factors and stroke. Results (1) There was a positive correlation between myocardial infarction and stroke in Yiyuan county, except for the incidence density of myocardial infarction and the incidence of stroke in some individual northern areas. And this synergistic change gradually decreased from west to east. (2) ) Malignant tumor and stroke showed a positive correlation between co-ordination, and this synergistic change relationship gradually weakened from north to south; (3) In addition to the western individual area of infectious diseases and stroke was negatively correlated, Yiyuan infectious diseases and stroke Showing a positive correlation between the changes in the co-ordination, which is greater in the central than the western and eastern relations, and showed a decreasing trend from north to south. Conclusion There is a spatial synergistic relationship between stroke, myocardial infarction, malignant tumor and infectious disease, suggesting that there may be some specific geo-social factors.
