【摘要】 采用因果关系模型对Ⅱ型糖尿病的危险因素进行了分析。用协方差矩阵配合模型的结果显示，精神因素对糖尿病的患病状况不仅有直接影响，同时也有间接影响。生活习惯对患病状况无直接影响，但它通过病人的生理状况对患病有间接影响。用相关系数矩阵配合模型结果显示，除上述影响糖尿病患病状况的因素外，还发现自我保健因子对患病状况有间接影响。同时，本文还讨论了用协方差矩阵和相关系数矩阵配合模型的特点。更多还原

【Abstract】 This paper presents the results of analysis of NIDDM risk factors using causing relationship model.Results of linear structural relation model based on covariance matrix showed that psychological factors affected the development of NIDDM not only directly but also indirectly.Patients’ life habits didn’t affect the status of NIDDM directly,rather it did indirectly through physiological factors.Based on the matrix of correlation coefficient,linear structural relation model was utilized for data analysis as well.Then results illustrated that self health care was found to be a protective factor by working directly,besides the influential factors above.Furthermore,the characters of fitted model using matrix of covariance and correlation coefficient were also discussed in this paper.更多还原
