Body Mass Index (BMI) is an index of a person's weight in relation to height, not body composition.
BMI values apply to both men and women, regardless of their age, frame size, or muscle mass. These values do not apply to athletes and body builders, pregnant and nursing women, frail or elderly persons or persons under 18. Use this information, along with other health indices, to assess your need to change your weight. A BMI of 25 or more indicates overweight, obesity is equal to or greater than BMI 30.
People who are overweight or obese have a greater chance of developing high blood pressure, high blood cholesterol, type 2 diabetes, heart disease, stroke and certain cancers.
This test should be used as a guideline and is based on information found in The Section of Diabetes and Clinical Nutrition, University of Southern California School of Medicine, Los Angeles.
