The difference between how BMI is calculated for adults and for adolescents reflects the fact that body fat changes with age and across genders as children grow into adults. A BMI from the 85 th to the 95 th percentile are considered overweight and anyone with a BMI in the 95 th percentile and above is obese. Those who fall between the 5 th and 85 th percentile have a healthy weight. Adolescents with a BMI below the 5 th percentile are considered underweight. For children and teens, this number is associated with a percentile that corresponds to where that BMI falls in these categories. How is BMI Read?īMI is represented as a number that corresponds to a specific weight category ranging from underweight to obese. To find the BMI for a child or teenager, use the CDC’s BMI calculator designed specifically for them. You can easily get your BMI without having to do any math by using the BMI Calculator for adults provided by the CDC. How is it Calculated?īMI is calculated by dividing a person’s weight by their height squared. While there are other methods for measuring body fat that are more precise, BMI is a simple, easy, no cost way to screen for possible weight related health problems. What is Body Mass Index?Īccording to the Center for Disease Control, body mass index is a cost effective and reliable method for determining body fatness for people of all ages, including children and teens. With all the buzz about BMI, many parents are left wondering whether or not it is a big deal and how it applies to their teenagers. It is calculated using your height and weight and shows whether you are underweight, overweight, obese, or at a healthy weight. BMI is actually three words, Body Mass Index, and it is a screening tool that can be used to gauge where someone falls on the weight continuum. We were taught about counting calories but today’s weight management buzzword, BMI, wasn’t part of our weight management vocabulary. We all knew how many calories we were supposed to be eating and how many pounds we were supposed to weigh. Most of today’s parents grew up thinking about weight management in terms of calories and pounds.
