Clinical Information

Body Mass Index - An indicator of body density as determined by the relationship of BODY WEIGHT to BODY HEIGHT. BMI=weight (kg)/height squared (m2). BMI correlates with body fat (ADIPOSE TISSUE). Their relationship varies with age and gender. For adults, BMI falls into these categories: below 18.5 (underweight); 18.5-24.9 (normal); 25.0-29.9 (overweight); 30.0 and above (obese). (National Center for Health Statistics, Centers for Disease Control and Prevention)

Obesity Paradox - An observation that high BODY MASS INDEX is sometimes associated with lower CARDIOVASCULAR DISEASE mortality in certain population, e.g., ELDERLY.
