Calculator: Estimated Risk of Developing Diabetes in 4 Years


The risk calculator below uses research data from the Strong Heart Study (Citation: DIABETES CARE. 2011;34:363-368 ) to estimate chance that a non-diabetic person who will develop diabetes in the next 4 years. It is designed for American Indians of age 35 and older. To find your estimated risk, enter your information in the calculator below. Definitions and descriptions of some terms in the calculator are provided at the bottom of the calculator.

Predicting risk of developing incident diabetes (DM) defined by either fasting plasma glucose (FPG) or hemoglobin A1c (HbA1c) (denoted as FPG/A1C-DM), or by HbA1c only (denoted as A1C-DM), or by FPG only (denoted as FPG-DM) in the next 4 years for a person who does not currently have FPG/A1C-DM, or A1C-DM, or FPG-DM, respectively (select one).

Your Estimated Risk:



Definitions and Descriptions



An incident FPG/A1C-DM event is defined by either having a fasting plasma glucose (FPG) >=126mg/dL, or having an hemoglobin A1c (A1C) >=6.5%.




An incident A1C-DM event is defined by having an hemoglobin A1c (A1C) >=6.5%.




An incident FPG-DM event is defined by having a fasting plasma glucose (FPG) >=126mg/dL.



    Your Estimated Risk : This percentage indicates the chance that you will develop diabetes in the next 4 years. For example, if your estimated risk is 20%, it means that 20 out of the 100 people who enter the exact same information as you did in the calculator would likely develop diabetes in the next 4 years.
