What is Body Mass Index (BMI)? Why we have to differentiate BMI between children and teenagers (up to 18) to adults?

BMI is a value obtained from the weight and height of a person. The BMI is defined as the body mass divided by the square of the body height, and is expressed in units of kg/m2.

The BMI is a convenient tool used to categorize a person as underweight, normal weight, overweight, or obese.

The BMI calculator for adults does not differentiate between age and gender, which are critical factors in evaluating growth in children. In adulthood, only single limits for overweight (BMI 25) and obesity (BMI 30) are used. For childhood and teenage years, which are marked by dynamic development, it is required to use percentile methods.

The thresholds for childhood obesity are lower than for adults, and so if a child exceeds a BMI of 30, then he or she is almost certainly obese.

Why children can't use same method of adults for calculating BMI (Body Mass Index)?

To calculate BMI for children, you can't use same methods as adults, because the main difference is that the method for adults does not take into considerations factors like gender (boys and girls grow differently), and age (the growing features changes every year in the childhood). For this reason, in this app we calculate BMI for children and teenagers, from 5 to 18 years old, based on the tables provided by the WHO. In these tables that are available in their website, there are hundreds of data of different ages, and different gender, and BMI is calculated comparing with the weight of other children of similar age and gender.

Using weight tables provided by WHO (World Health Organization). This app calculates BMI for children and teenagers with official data, taken by many tables provided by the WHO, which is an international organization that controls weight worldwide.
