What is Body Mass Index?
|
BMI is a calculation that uses your height, weight, age and sex to determine how you are growing.

How is BMI Calculated?
|
Nothing will change during your school growth screening. The school will measure your height and weight just like they have always done. What's new is that those numbers will be entered into a formula and your BMI and BMI percentile will be calculated. |
|
What will be done with the numbers?
|
The school will then send this information home to your parents/guardians and ask them to share this with your family doctor. Your friends and teachers won't know your BMI unless you tell them.

Why is it good to know about BMI?
|
Being overweight can lead to illnesses, such as diabetes, heart disease, breathing problems, joint problems and depression. Plus, being overweight as a child or teenager greatly increases your chances of being overweight as an adult. Being underweight can cause harm to your heart, kidneys, muscles and bones, and may lead to anemia. A high or low BMI is just one of many risk factor for these illnesses. However, the more risk factors you have, the greater the chance you will develop one of these diseases.

BMI - just 1 piece of the puzzle. |
When it comes to your weight, BMI is NOT the whole story. A child who is very muscular, like an athlete, may have a higher weight and BMI but not have a lot of body fat. Two people with the same BMI may have different body fat levels. That's why you need to share this information with your family doctor. |

My BMI is high. Now what?
|
Talk to your parents/guardians and your doctor about what to do to lower your BMI. Unlike adults, you should NOT go on a diet. Eating healthier and exercising more can improve your BMI. Remember, lowering your BMI to a healthy level now will help to prevent problems as you get older.
