Most of us have been weighed at the doctor’s office. Some of us may have brought children to the doctor where they are weighed. It can be uncomfortable, and even stressful. Then, the doctor comes in and starts talking about the number on the scale and another number known as BMI, or body mass index.
What is this number? What does it mean that I’m a 19, or a 24, or a 31? Turns out, it might not mean that much in terms of your health.
BMI is a number that combines weight and height using the formula BMI = kg/m^2. This number was thought to be useful since 100 pounds for a little kid is different than 100 pounds for a fully grown adult. The medical world has decided that certain BMI values are deemed a healthy weight [for height] and that values outside this range are less healthy, or may come with health risks.
Actually, however, BMI is not a good indicator of being at a healthy weight or not at a healthy weight.
It is easy to measure the height and weight of someone. It is harder to use other [more informative] measurements, like body composition or waist circumference.
However, any measure of body weight/size does not accurately reflect an individual’s health status and often leads to ineffective interventions rather than efforts that enhance health and wellness.
Hopefully, the BMI system is on its way out as more healthcare professionals recognize that health exists on a continuum that varies with time and circumstance for each individual.
A number does not define you or your health. Not the number on the scale, not your pants size, and not your BMI.
