where:
• extreme obesity: BMI >= 40 kg per sq m; waist circumference >= 50 inches men; waist circumference >=49 inches for women
• obesity: BMI 30-39.9 kg per square meter; waist circumference 40 to 49.9 inches in men; waist circumference 35 to 48.9 inches women
• overweight: BMI 25 to 29.9 kg per sq m; waist circumference 37 to 39.9 inches in men; waist circumference 31.5 to 34.9 inches in women
score =
= SUM(points for all 6 parameters)
Interpretation:
• minimum score: -1
• maximum score: 9
• A score >= 5 is associated with an increased risk for diabetes.
• A score >= 4 is associated with increased risk for prediabetes or diabetes.
Performance:
• The cutoff of >= 5 has a sensitivity of 79% and specificity of 67%.
