Based on
Wilson PW, Meigs JB, Sullivan L, Fox CS, Nathan DM, D’Agostino RB. Prediction of incident diabetes mellitus in middle-aged adults: the Framingham Offspring Study. Archives of internal medicine. 2007 May 28;167(10):1068-74. PMID:17533210.

Outcome
Type 2 Diabetes Mellitus (fasting blood glucose at or above 126 mg/dL)

Duration of follow-up
Average of 7-years, 8-year risk prediction

Population of interest
Individuals 45 to 64 years

Predictors

  • Age categories
  • Gender
  • Fasting Glucose above 100 mg/dL
  • BMI (Body Mass Index) categories
  • HDL cholesterol categories
  • Triglyceride above 150 mg/dL
  • Blood Pressure categories
  • Parental History of Diabetes

1+e -z

z = ß0 + ß1x1 + ß2x2 + … + ßkxk
where z indicates regression equation with beta coefficients taken from table above (ß0 as intercept) and x’s indicating values of corresponding risk factor (0 or 1 for each category)
