Body Mass Index (BMI)

Calculate your Body Mass Index with the calculator provided by Center for Disease Control and Prevention. (If you are a child or teenager, use this calculator.)

Body Mass Index (BMI) or Quetelet Index is used to determine a person’s total fat, which is related to the risk of diseases. If a person’s BMI is greater than 25, the National Heart, Lung & Blood Institute recommends weight loss, especially if the person has a high waist measurement.

BMI is frequently used to determine the following categories:

Category BMI range – kg/m2
Starvation less than 15
Underweight from 15 to 18.5
Normal from 18.5 to 25
Overweight from 25 to 30
Obese from 30 to 40
Morbidly Obese greater than 40

What to take into consideration:

  • The score may overestimate BMI for those who are greatly athletic or have a lot of muscle mass.
  • The score may be underestimated for those who are older or have a small amount of muscle mass.

Harvard: Body Mass Index

According to the Harvard web site, BMI is only one of the many tools used to predict risk factor for diseases.

Diseases and conditions associated with obesity include the following: cardiovascular disease, high blood pressure, osteoarthritis, diabetes, sleep apnea, and some types of cancers.

Waist Measurement

According to the Medical College of Wisconsin, because BMI may not be completely accurate, one should also measure their waist as this measurement is used in conjunction with BMI to help access risk.

To measure your waist, “place a tape measure around your bare abdomen just above your hip bone. Be sure that the tape is snug, but does not compress your skin, and is parallel to the floor. Relax, exhale, and measure your waist.”

You may be at risk if:

  • You are female and your waist measures more than 35 inches.
  • You are male and your waist masures more than 40 inches.
