Your doctor knows your number; your insurance company might
know your number. But do you know what your BMI is, and why you should care?
A BMI, or Body Mass Index, is a number derived from your
height and weight. A BMI of 20-24.9 is considered normal weight, 25-29.9 is
considered overweight, and 30 or above is considered obesity. If you are
curious, go here to figure your BMI at the National Institutes of Health web site. They have a number of links
for helping you work on a healthier weight, too.
Insurance companies in this area are starting to key in on
participants’ BMI, and are offering those with a BMI of 30 or above various weight
loss programs, such as Weight Watchers and a pedometer program. The incentive
to do either of these is lower co-pays for insurance-covered benefits.
So why does a BMI of 30 or more matter? Because that’s the
point that a person is more likely to have trouble with blood pressure, blood
sugar, heart disease, joint pain, etc.
Even though the BMI is an indicator of potential health
issues, there are problems with using BMI as the only indicator. For example, a
person who is very fit yet very muscular (such as athletes and those with very
physical jobs) may have a BMI of 30, yet have no health problems. To get a true fitness and health
reading, you would need to have your waist-to-hip measurement, your percent
body fat, oxygen capacity, and other measures taken. For now, we are stuck with being graded by our BMI.
If you have a BMI of over 30 and would like to get going on
a pedometer program on your own, here is a place to learn more, from the people at About.com.
