BMI does not directly measure body fat. Waist-to-height ratio adds context about central adiposity; it should be interpreted alongside other health information.

How the results are interpreted

• Standard adult BMI categories use internationally established screening ranges.
• BMI ≥30 is subdivided into obesity Classes 1, 2 and 3.
• A waist-to-height ratio below 0.50 is the commonly used central-adiposity boundary; 0.50–0.59 and ≥0.60 indicate progressively higher risk ranges.
• Population-specific BMI thresholds can identify risk at lower BMI values in South Asian/Indian populations.
