The Body Mass Index— published: 08-01-2011
You may have heard about the Body Mass Index (BMI), but do you really know what it is? BMI is an indicator of body fat for most adults—a screening tool for possible health problems. BMI is calculated using weight and height, and depending on the number, the result is categorized into underweight, normal weight, overweight, and obese. The higher the BMI, the higher the risk of certain diseases such as heart disease, high blood pressure, Type 2 diabetes, and certain cancers. The Centers for Disease Control and Prevention has an adult BMI calculator, child and teen BMI calculator, and information for interpreting the numbers.
