How does childhood obesity work?

According to the Centers for Disease Control, approximately 30.3 percent of children ages six to 11 and 30.4 percent of adolescents ages 12 to 19 are either overweight or obese. That's almost one out of every three kids in America.

The CDC uses the scientific Body Mass Index formula to measure obesity (they never actually use the word "obese" in their reports). A combination of your height and weight, a BMI score of 25 or higher indicates that you are overweight, while a BMI score of 30 or more indicates obesity. For more information on Body Mass Index, as well as a calculator you can use to easily find your own BMI score, check out How Body Mass Index Works.

Childhood Obesity (a BMI score of 30 or more) is a serious health risk. It can lead to all sorts of problems, from heart disease and bone trouble to social and psychological trauma. And the problem is growing. Today, twice as many children ages six to 11, and three times as many adolescents ages 12 to19, are obese than they were just 20 years ago.

So what's the deal? Why is this happening? Is it really a bad thing, and what can we do about it? In this article, we'll take a closer look at childhood obesity. We’ll find out who’s at risk of being obese, what the consequences are and what's being done to combat this national health epidemic.
