Which measure correlates best with obesity-associated disease risk?

Which measure correlates best with obesity-associated disease risk?

• A. BMI
• B. Skinfold thickness
• C. Abdominal body shape index
• D. Waist circumference

Answer: (D)

Central fat, especially visceral fat, drives the metabolic problems that raise disease risk. Waist circumference is a direct proxy for abdominal adiposity, so it correlates more strongly with obesity-related conditions like insulin resistance, dyslipidemia, hypertension, and inflammation than overall body weight alone. Body mass index measures how much someone weighs relative to height but doesn’t tell you where fat sits in the body; two people can have the same BMI and very different metabolic risks if one carries more fat around the abdomen. Skinfold thickness estimates subcutaneous fat and misses the visceral fat that’s most closely tied to disease risk. A newer index that tries to capture shape can be informative, but the strongest and most consistent evidence links waist circumference with obesity-associated disease risk across diverse populations, making it the best single measure for this purpose.
