Prediction and evaluation of population at high risk of 2 type diabetes mellitus

  Objective   Based on a nested case control study on the risk factors of type 2 diabetes and IFG, mathematical models for the risk factors of the disease were developed.

  Methods   Waist hip ratio or waistline was used for the predicting index of population at high risk of 2 type diabetes, and the effectiveness was evaluated.

  Results   For under the age of 40 years, the sensit ivities were 100%.The specificities were 80% and 77% and Youden's index were 0.80 and 0.77, respectively.The effectiveness of over 40 years was lower than under the age of 40.

  Conclusion   WHR or waistline was a simple and effective predicting index for under 40 years of age.
