The BMI index is an especially useful tool for children and teens because their rate of growth and development can be monitored over a period of time, and it can be used to track body size throughout their life.
In children, teens, and adults body mass index is used to assess underweight, overweight and obesity. Measuring BMI in adults is a number derived by a simple formula. For children, calculating BMI is more complex. Children's body fatness changes over the years as they grow. Also, girls and boys differ in their body fatness as they mature. Therefore, age, gender, weight and height are key factors. To determine a child's BMI, it is easiest to use a BMI calculator that is designed for kids.
The Children's Nutrition Research Center at The Baylor College of Medicine has a very easy to use online calculator. Before going to the site, you will need to know your child's age, height and weight. The calculator will provide you with an instant result. Make sure you read the whole page, because it provides you with an easy way to track your child's BMI as they grow. If you have specific questions about your child's results, we suggest that you contact your pediatrician. Click here to view the BMI calculator for children.
