Category - Basal Metabolic Index (BMI)

Basal Metabolic Index (BMI): BMI or Body Mass Index is a statistical measure which compares a person’s height and weight in order to determine their overall body composition and fat. If the BMI classification is beyond normal, then the person would be considered obese and have an increased risk of cardiovascular disease.  Although BMI doesn’t measure body fat directly, it uses the weight and height to determine whether an individual is classified as underweight, normal weight, overweight or obese.

BMI is measured by dividing a person’s weight in pounds by the square of their height in inches, then multiplying by 703. The equation looks like this: BMI = (weight / height x height) x 703.

For example if an individual is 125 pounds and 5 feet 4 inches, then the BMI = (125 / 64 x 64) x 703 = 21.4. This BMI puts the individual in the normal weight range.

This measurement correlates moderately well with other measurements of body fat such as skinfold measurements and underwater weighing according to the Centers for Disease Control and Prevention.
