Obesity, Height and Weight


Except for those who are extremely muscular, people whose weight is 20 percent or more over the midpoint of their weight range on a standard height-weight table are considered obese. Obesity may be classified as mild (20 to 40 percent overweight), moderate (41 to 100 percent overweight), or severe (more than 100 percent overweight). Obesity is severe in only 0.5 percent of obese people.

Traditionally, obesity has been defined as a body weight of > 30% above ideal or desirable weight on standard height-weight tables. Now, it is usually defined in terms of the body mass index (BMI): weight (in kilograms) divided by the square of the height (in meters).

From The American Obesity Association

For children, The American Obesity Association uses the 85th percentile of BMI as a reference point for overweight and the 95th percentile for obesity.

These reference points are used because:

  • The 85th percentile corresponds to a BMI of 25, which is the overweight marker for adults.
  • The 95th percentile corresponds to a BMI of 30, which is the marker for obesity in adults.
