Body Mass Index Children US

BMI children USThis module calculates Body Mass Index for children from age 2 to age 18 and classifies the result according to the guidelines given by the U.S. Department of Health & Human Services. It also has an optional evaluation of height in relation to age.

Instructions:
1. Enter values for gender, height and weight.
2. The result is interpreted within four categories: Underweight (<5th percentile), Healthy weight (5th-85th percentile), Overweight (85th-95th percentile) and Obese (>95th percentile).
3. Please note, that BMI is only a very rough predictor for overweight in individuals.

Background

For adults, the body mass index limits for overweight and obesity are straight forward (overweight = BMI > 25 and obesity = BMI > 30). For children this is much more complicated as the limits vary a lot depending on age. This calculator uses the US guidelines that are based on fixed percentiles from a large reference population. 

A BMI of 20 indicates obesity in a 6 year old girl, whereas it would represent healthy weight for a 13 year old girl. However, as growth of children varies, the final evaluation should always be based on a several factors including physical growth, muscularity and subcutaneous fat deposits.

The calculator also includes the possibility to evaluate height in relation to age. If the child/youth scores in the high percentile range on height (above average) this could indicate that physical development is ahead of chronological age. As higher BMI is expected with increasing age (above age 6), this information can assist in a qualified evaluation of BMI.

Quoting Sophia Habermehl:
Hi, I have been wondering is it bad that i am 10, turning 11 in september, (It is April 8th, 2021) and im 5'3, and weigh around 143 lbs?? -Sophia.

I think that is something to worry about Sophia. I'm pretty sure overweight for a 10 year old is 102 pounds or something like that...but you are pretty tall so I don't really know.

Hi I am 14 years old and 5'8", I weigh about 92 pounds, but last week I was 134. My best friend told me that it wasn't healthy and that I weighed less then her but she isn't even 5 ft. I have body image issues so I am still wanting my weight to be lower. Am I underweight? It doesn't show on my body though I look like I should weigh a lot more than I do. I am a ballet dancer though so I know a good amount of my weight is muscle but I also know there is a lot of fat. Please help me understand.
