Calculate BMI using the NIH (National Institutes of Health) classification system with disease risk assessment.
The National Institutes of Health (NIH) classification system combines BMI categories with waist circumference to assess the risk of developing obesity-related diseases like type 2 diabetes, cardiovascular disease, and hypertension.
The NIH uses standard WHO categories but adds disease risk assessment by combining BMI with waist circumference. This provides a more complete picture than BMI alone.
