This index mathematically relates
height and weight for a result that is a good indicator of body
fat. It is a better predictor of health risk than weight alone.
This formula is most accurate for adults other than body builders,
competitive athletes, and pregnant or breastfeeding women.
BMI is determined by calculating the weight in kilograms divided
by the height in meters squared.
How does BMI relate to health?
The BMI ranges are based on the effect body weight has on disease
and death. As BMI increases, the risk for some disease increases.
Some common conditions related to overweight and obesity include
* Premature death
* Cardiovascular disease
* High blood pressure
* Osteoarthritis
* Some cancers
* Diabetes
BMI is only one of many factors used to predict risk for disease.
BMI cannot be used to tell a person if he/she has a disease
such as diabetes or cancer. It is important to remember that
weight is only one factor that is related to disease.
