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。
The causal relationship model was used to analyze the risk factors for type 2 diabetes. Co-variance matrix with the model results show that mental factors on the prevalence of diabetes not only have a direct impact, but also indirectly. Living habits have no direct effect on the condition, but it has an indirect effect on the condition through the patient’s physical condition. Correlation matrix model with the correlation coefficient results show that, in addition to the factors that affect the prevalence of diabetes, but also found that self-care factors have an indirect impact on the prevalence. At the same time, this article also discusses the co-variance matrix and correlation coefficient matrix with the characteristics of the model.
