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.

My partner is attempting to keep me off the internet as she believes I spend far too much time on it.

Having said that, I do enjoy filling up my head with as much knowledge that I get my
hands on. I also always like to take the time to thank people if they have taken the
time to help me, which explains why I'm commenting now.
Many thanks for this useful article.

Hello I´m Sarah and I am 13 year old
(5´2) (108 pounds) with EDS. Moving around is very hard for me so Im trying to work out and lose weight so in future I wont be overweight. To lose weight I dance. If you are trying to lose weight I suggest burning 600 calories a day and getting 7-8 (or more) hours of sleep and you maybe will lose two pounds in one week. Losing weight takes time so dont starve yourself it wont help trust me. I hope this helps anyone trying to lose weight.

Losing weight takes time. Try looking up work outs and try to burn at least 600 calories a day and get 7-8 or more hours of sleep and you should lose two pounds a week. Remember just dont give up. Hope this helps.

Please someone respond and be honest.. Also remember that confidence is beautiful, no matter your size, no matter your weight, be confident in who you are and you will be beautiful.
