How to use the Diabetes Risk Calculator

What this calculator does
The score adds 1 for age >=45 and another 1 for age >=65, then adds points for family history, overweight, inactivity, sex-specific waist thresholds (102 cm male or 88 cm female), blood pressure >=140, A1C 5.
Formula and method
The score adds 1 for age >=45 and another 1 for age >=65, then adds points for family history, overweight, inactivity, sex-specific waist thresholds (102 cm male or 88 cm female), blood pressure >=140, A1C 5.7-6.4 (+1) or >=6.5 (+3), and female-only gestational diabetes or PCOD. Risk percent is min(80, score * 8); levels are Low for 0-1, Moderate for 2-3, High for 4-5, and Very High for 6 or more.
Variables and inputs
Enter age, the male or female option, waist in centimeters, blood pressure in mmHg, HbA1c as a percent, and the displayed yes/no factors. The blood-pressure input is one number and the engine compares it with 140; it does not accept a separate diastolic value. Female-only checkboxes appear only for the female option.
Worked example
With age 45, male, waist 90 cm, blood pressure 120, HbA1c 5.5%, no family history, not overweight, physically active, and no other flags: the general age rule adds 1 point and the male age >=45 rule adds another, so the score is 2, the mapped estimate is 16%, and the level is Moderate Risk.
How to interpret the result
The result is a screening score assembled from the route's selected factors. The displayed percentage is a linear point-to-percent mapping capped at 80%, not a validated probability that a particular person will develop diabetes.
Common mistakes to avoid
Enter HbA1c as 5.7 for 5.7%, not 0.057, and use centimeters for waist. Notice that checking Physically Active means no inactivity point; do not enter a full blood-pressure pair because the engine reads only one number.
Assumptions and limitations
This is not a diagnostic or validated risk model. It omits many factors, does not confirm A1C or blood-pressure measurements, uses a simplified waist and pressure rule, and includes PCOD terminology and sex-specific branches that may not fit every person. Pregnancy, symptoms, and abnormal test results require professional evaluation.
