Classification of childhood obesity

"Okay kiddo, let's talk about something called obesity in kids. Obesity means that someone has too much body fat, which can be unhealthy for them. But not all kids with obesity are the same. They can be put into different categories based on how much body fat they have.

There are three categories of childhood obesity: overweight, obese, and severely obese. Being overweight means that a kid has a little bit more body fat than they should have for their age and height. Being obese means that they have a lot more body fat than they should have. And being severely obese means that they have too much body fat that it can affect their health.

Sometimes, doctors use a special measurement called the BMI (body mass index) to figure out if a kid is overweight, obese or severely obese. The BMI measures a kid's weight in relation to their height. It helps the doctors see if the kid's weight is healthy and appropriate for their age and height.

Now, why is it important to know these categories? Because it helps doctors, parents and the kid themselves to understand how their weight affects their overall health. For example, if a kid is in the obese or severely obese category, it's important to make some changes to their lifestyle like eating healthy foods and being physically active to prevent health problems like diabetes, high blood pressure and heart disease.

So, it's important for kids to maintain a healthy weight, and if they are overweight or obese, there are different categories to know how much they need to work on their healthy habits. And with the right habits and support, they can become healthy and happy kids!"
