How do you determine obesity?

Obesity is defined as a generalized accumulation of body fat. It is measured by the body mass index (BMI), which is determined by a person's height and weight.

Calculate Your Body Mass Index (BMI)

Supplied by BMI Calculator USA

  • A person with a BMI of 25 to 29.9 is considered overweight.
  • A person with a BMI of 30 or greater is considered obese.
  • A person with a BMI of 40 or greater is considered extremely or morbidly obese.

It is important to remember that BMI is just one number among a host of information that a care and support team will solicit from a child and their family. Diet, activity levels, environment, genetics and other factors are all relevant in making assessments and treatment plans.
