Special Obesity Fact File

2501/ Americans are not the heaviest people in the world. For example, of American women, ages 20 to 74, 62 percent are overweight (Body Mass Index (BMI) of 25 or more) and about half of that population (34 percent) is obese (BMI of 30 or more). Nearly identical to the rate in Bahrain, Paraguay and Malta, according to the London-based International Obesity Task Force. But Pacific Islanders have the world's highest obesity rate - 75 percent among Samoan women.

2502/ You can calculate your own Body Mass Index in the following way.

Weight in Lbs ÷ height (in)2 x 704.5 = BMI

eg You weigh 13 stone 4 lbs and are 5 foot 9 inches tall. There are 14 lbs in a stone (Please note 1 kilogram = 2.20462262 pounds) - So you weigh 186 Lbs. 1 Foot = 12 inches. So you would be 69 inches tall.

Then to calculate your BMI:

186 ÷ (69 x 69) x 704.5 = BMI

ie 186 ÷ 4761 x 704.5 = 27.52 Body Mass Index

A BMI between 20 - 25 (ignore any statistics like these if you are pregnant) is about right. 25 - 30 and you are overweight. Above 30 you are obese. Above 40 and you are severely obese. Under 20 and you are underweight.
