Obesity is often measured using BMI, waist-circumference and/or waist-to-hip ratio.
Body Mass Index (BMI)
Body Mass Index (BMI) is a mathematical calculation involving height and weight. It does not take into account family history, gender, age or race.
BMI is calculated by dividing a person's body weight in kilograms by their height in meters squared (weight [kg] height [m]²) or by using the conversion with pounds (lbs) and inches (in) squared.
BMI can be a misleading number for very muscular people, and for pregnant or lactating women.
|30 and greater||Obese|
|40 and greater||Morbid or extreme obesity|
Waist circumference is another widely used measurement to determine abdominal fat content. An excess of abdominal fat, when out of proportion to total body fat, is considered a predictor of risk factors related to obesity. Men with a waist measurement exceeding 40 inches are considered at risk. Women are at risk with a waist measurement of 35 inches or greater. Waist-to-hip ratios are often predictors for increased risk of myocardial infarction, stroke, and premature death.
