Formula Used

Risk Score = Age Factor + BMI Factor + Waist Factor + Family History Factor + Activity Factor + BP Factor

Where:

Age Factor = Points based on age range (0-3 points)
BMI Factor = Points based on BMI category (0-2 points)
Waist Factor = Points based on waist circumference (0-2 points)
Family History Factor = 1 point if positive family history
Activity Factor = Points based on activity level (0-2 points)
BP Factor = 1 point if diagnosed with high blood pressure

Example Calculation

Real-World Scenario:

A 45-year-old male who is 178 cm tall, weighs 95 kg, has a waist circumference of 102 cm, has a sedentary lifestyle, a family history of diabetes, and has been diagnosed with high blood pressure.

Given:

Age = 45 years
Height = 178 cm
Weight = 95 kg
Waist circumference = 102 cm
Physical activity = Sedentary
Family history = Yes
High blood pressure = Yes

Calculation:

BMI = 95 / (1.78)² = 30.0 (Obese category) = 2 points

Age Factor (45 years) = 2 points

Waist Factor (102 cm for male) = 2 points

Family History Factor = 1 point

Activity Factor (Sedentary) = 2 points

BP Factor = 1 point

Result: Total Risk Score = 2 + 2 + 2 + 1 + 2 + 1 = 10 points (High Risk)

Common Mistakes & Tips

Ensure accurate measurements for height, weight, and waist circumference. Measure height without shoes, weight with minimal clothing, and waist at the level of the navel while standing relaxed.

Be honest about your family history of diabetes. Include parents, siblings, and children when considering family history. Even if they developed diabetes later in life, it still counts as a risk factor.

Be realistic about your physical activity level. The activity categories refer to regular, sustained exercise, not occasional activities. Walking for 10 minutes once a week doesn't make you "moderately active."

Frequently Asked Questions

This calculator provides an estimate of your diabetes risk based on established risk factors. It's not a diagnostic tool but can help identify if you're at higher risk. For a definitive assessment, consult with a healthcare provider who may recommend blood tests.

If your risk is high, consider making lifestyle changes such as increasing physical activity, improving diet, and achieving a healthy weight. Consult with a healthcare provider for personalized advice and to determine if further testing is needed.

Yes! Research shows that lifestyle changes can prevent or delay type 2 diabetes in high-risk individuals. Losing just 5-7% of body weight and getting 150 minutes of moderate physical activity per week can significantly reduce your risk.
