山东省糖尿病死亡率的趋势面分析

目的：研究山东省糖尿病死亡率的地理分布规律。方法：应用趋势面模型探讨山东省2000年各疾病监测点糖尿病的死亡率空间分布趋势。结果：鲁西北和胶东地区为糖尿病高死亡区域，而鲁中、鲁西南、鲁南的糖尿病死亡率水平相对较低。另外，某些地区的剩余值明显高于或低于剩余界值，属局部异常点。结论：山东省糖尿病死亡率呈明显的地域分布规律，为进一步探讨其地理危险因素提供了理论依据。

Trend-surface analysis of the geographical distribution of diabetes in Shandong Province

Objective:To study the distribution of the mortality of diabetes in Shandong Province.Methods:The diabetes mortality of different regions in Shandong Province in2000was investigated based on the methods of the trend-surface analysis.Results:Diabetes mortality was lower in the center and south-west,esclating from the center to east and north-west.In addition,the residual value in some areas exceeded the limited residual value,which indicated that some particular affecting factors maybe exist in those areas.Conclusion:The mortality of diabetes has geographical distribution trends in Shandong Province.Research should be performed on the difference of the environment and living habit,the econom-ic situation in different areas,and the relationship between these factors and the relative diabetes mortality.Attention should also be paid to the areas whose residual values are anomalous to study the particular protecting or hazardous factors.
