Body Mass Index (BMI) is a measure of body fat based on height and weight that applies to children and teenagers. It’s a tool that healthcare providers use to screen for weight problems such as underweight, overweight, and obesity.
To calculate your child’s BMI, you’ll need to know their height and weight. Once you have that information, you can use the following formula: BMI = (weight in kilograms) / (height in meters)2. For example, if your child weighs 50 kilograms and is 1.5 meters tall, their BMI would be 22.2.
