【摘要】：目的揭示我国中老年人室间隔厚度参考值与地理因素的关系。方法收集71个市县3 996例健康中老年人室间隔厚度参考值,应用SPSS19.0软件对其与17项地理指标进行相关分析,选取相关性显著的7项地理指标进行岭回归分析,使用克里格插值法探索我国中老年人室间隔参考值的空间趋势分布。结果我国中老年人室间隔厚度参考值与其中7项地理因素具有显著的相关性。线性回归方程为:嬗=10.91-0.016 51X1+0.000 380 0X3-0.001 090X9+0.012 66X10-0.041 00X14-0.004 100X15+0.018 30X16±1.55,并从空间趋势分布图得出我国中老年人室间隔厚度参考值的分布规律大致上从东往西逐渐升高。结论若知道中国某地区的地理要素,可通过上述模型估算该地区中老年人室间隔厚度参考值。
[Abstract]:Objective to reveal the relationship between reference value of interventricular septum thickness and geographical factors in middle-aged and elderly people in China. Methods the reference values of interventricular septum thickness were collected from 3 996 healthy middle-aged and aged people in 71 cities and counties. The correlation analysis was carried out with SPSS19.0 software with 17 geographical indexes. Seven geographical indexes with significant correlation were selected for ridge regression analysis. The spatial trend distribution of reference values of interventricular septum in middle-aged and elderly people in China was investigated by Kriging interpolation method. Results there was a significant correlation between the reference value of interventricular septum thickness and 7 geographical factors in middle-aged and old people in China. The linear regression equation is: range = 10.91 脳 0.016 51X1 0.000 380 0X3-0.001 090X9 0.012 66X10-0.041 00X14-0.004 100X15 0.018 30X16 卤1.55, According to the spatial trend distribution map, the distribution rule of the reference value of interventricular septum thickness in middle-aged and old people in China is gradually increasing from east to west. Conclusion if we know the geographical factors of a certain area in China, we can estimate the reference value of the interventricular septum thickness of the middle-aged and old people in this area by the above model.
