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.

Hello all! I’m a 10 year old girl and I weigh 88 lbs. I’m currently about 5’3. Am I overweight?

Your under weight, you should at least 90-100. But you are growing still. Wait till you are 13. You shouldn't be worrying about that yet. You are still a kid. Wait till you are in your teens 13-19
