What it makes this specific calculation appropriate is that it uses other data to compare and determine whether the child is underweight, in a normal weight range or overweight. Using the BMI percentile in assessing your child’s weight and height can help you compare his or her development to the general tables and therefore to other children but is also related to important health risks. BMI 85th to 94th percentile: Overweight.BMI 5th to 84th percentile: Healthy Weight.This works as a great guideline to assess the current weight of a child or teen. This useful tool for all parents and pediatric specialists will return not only the mass index value but also the child’s weight status category according to the percentile range in which the BMI stands for the given case. Example BMI calculationĬhild’s weight status category: UnderweightĬhild’s percentile is below 3 rd percentile BMI= mass (kg)/height (m)^2 but then this result needs to be compared with the appropriate tables for the age and gender of the child. The basic BMI calculation isobtained through dividing the weight in kilograms by the square of the height in meters. There is also a distinction made between 85 and 95 for overweight. What there is to keep in mind is that a percentile below 5 means underweight while everything that is above 95 means obese. The form above provides both the BMI value and the corresponding BMI for age percentile on a CDC BMI for age growth chart. This is where BMI percentile calculation takes place, when comparing the result by age and gender. So the body mass index for kids gets calculated using the same types of measurements as the adult version but then the result is compared to typical values of the development of children at the same age. Not to mention the gender as we all know that there are important differences in the way girls and boys develop, in regard to mass and height. However, when it comes to children, these index needs to be refined as to take into consideration the ratios of development for each age. The BMI is generically known as an index provided to determine the harmonious or not relationship between the weight and the height. The weight tool above can be used for children and teens with ages ranging from 2 to 19 years old.
You should also consider which measurement you want to use and stick to it, so you take the weight in kg and the height in cm or the weight in lbs and the height in inches. What you need to take into consideration is that any small error that could occur during the measurements will lead to a large error in the results and therefore to an inaccurate determination. In order to determine the BMI percentile it needs the height, weight and age. The tool has two tabs that are designed to make the calculations for the two measurements systems, English and metric. This BMI calculator for kids returns the body mass index (BMI) value based on child’s age, gender, height and weight together with the child’s weight status category and with the percentile range values. How does the BMI calculator for kids work?
