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, I’m almost 14 years old and I weigh only about 9 pounds . My body wasn’t ment to hold and food or drinks so I have to starve myself. I can’t fit in with the others.
I have had anorexia for my whole life. I’m just a skeleton. I could die any day. I’m always cold even when it’s summer, still it freezing for me. I wish I could gain weight, so I could enjoy the small life that I live. I’m just as thin as paper. I can’t go anywhere, I can’t walk my legs won’t hold me up. I have to use a wheelchair to get around.

Hi, I’m 11, 4’10 and right around 24 pounds. I’ve suffered from anorexia since I was 8 years old. I can’t seem to get better. I never really ate a lot. I don’t even want to touch a drop of water now. When I was 7 years old I got bullied for being a little bigger than the other kids. I was about 70 pounds.
Especially the really skinny kids bullied me. When I decided I needed to change so I did. Now I have anorexia. I basically live in a hospital i’ve Been in the same hospital room for over 3 years now.

Hi I’m Keeley, I am 13 I’m 5”9 and I weigh 115. I seem like I weigh a lot but it’s mainly my height. I don’t look heavy and I am pretty skinny. If you don’t love your body, change it no matter what because all that matters is that you are comfortable living in your skin.

Hi Jenna, try going on the keto diet, it's a diet that instead of your body burning sugars and carbs it starts to burn fat by you eating foods with high fats and low sugars and carbs
