摘要
收集中国30个省份的8 978例城市健康青年男性收缩压参考值,应用SPSS 17.0统计分析软件,综合运用相关分析和回归分析的方法,研究其与9项区域地理环境指标的关系。运用多元回归分析、曲线估计和主成分分析估计中国男性青年收缩压指标的正常参考值,得出不同的收缩压预测模型。结果发现,健康青年男性收缩压参考值与中国地理因素间有显著相关关系(F=12.003,P=0.000)。健康青年男性收缩压参考值的预测模型为:YSBP=55.155+0.004 x2+0.712 x3+0.160 x8+0.519 x9。
With the change of global climate and ecological environment, more and more people become more concerned with the relationship between the environment and the SBP reference value. This paper discussed the relationship between the SBP reference value of the fiealth adolescent boys and the geograph- ical factors. 8978 cases of the health adolescent boys were collected in 30provinces of China, and the corre- lation analysis was used to find the correlation of the geographical factors and the SBP reference value of these young men. The SPSS software was used to get the study of these relationships. In order to get the best result, the regression analysis, the curve analysis and the main fact.oranalysis were chosen. In order to get the best result, we chose the regression analysis, the curve analysis and the main factor analysis alto- gether. Through the Comparison of the Real value and the Predicted value, we got the three different fore- cast model through these analysis, and then we chose the best forecast model through the comparison of three different models. The result shows there is significant relationship between the geographical factors and SBP reference value. And the forecast model is： YsBp=55.155＋0.004 x2＋0.712 x3＋0.160 xs＋0.519 x9.The spatial distribution of the reference SBP value in different areas of China was abstained also, And in order to reveal the distribution regularity of the normal reference value of young men in China and provide a sci- entific basis for making a unified standard of the normal SBP reference value, we also get the thematic map of the distribution of the reference value in different areas of china, the distribution condition of the SBP value can be clearly reflected through the map, if any one want to read the SBP reference value of dif- ferent areas of china, we can read the reference value of the adolescent boy＇ s SBP reference value through the map. This paper give the scientific foundation for making the SBP value. Through all these analysis, we find that the 9 Geographical Variables are all closely related to the normal SBP reference value of chi- nese young men.
