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.

I'm a 14 year old,female, 5' and I'm 133 lbs. My doctor said it's in the range of normal but this website says it's overweight, I'm confused? I started puberty at 9 so my doctor says I have the same body and average weight I will for the majority of my life tho.

You need to stop. I literally cannot make out what you are saying because you are using such poor grammar. You need to stop judging girls with low self esteem. Nobody wants to hear your negative comments about young girls.

I am a 12 year old girl I am '5 "3" and 190 is that bad????!!!!

If your 190 a girl and only 5 "3" then you are what i call a obese american like my god im at least 5 "11" a boy and i go to the gym and weight 198 thats normal but i dont known what to say thats bad go hit a gym and lose it
How rude and ignorant! You are 14 calling a 12 year old an 'obese american'! Fat shaming is not okay. Lily, if you feel confident and comfortable about your body/weight, it's not bad. There is no normal! I have always dealt with being fat shamed. I have learned to not listen because I believe I beautiful and confident.

HI I'm darnell I'm 272lbs I play lots of sport I play travel volleyball and travel football I'm the captin on both teams I also run track I'm very unique last year at my track meet I shocked every one when I came in 1st in my 3 events shot put, 100 meter dash and 200 hundred meters Im very active and at dinner time I usually have only 2 plates of food I'm also 5'8. I have tried diet but it doesn't help I really need help

Try making your plates and portions smaller, it tricks the mind. Also focus on eating. You can get fat from not focusing on eating, if you doing something else while your eating.

im 12, im around 130 pounds. my BMI is 92, anyway i can get to my goal which is 90- 80 pounds? im thinking about eating little to none.

That is QUITE a bad idea. Eating little to none is very bad for growth and health. Eating healthier is a better option, but eating less is always a good idea if you eat too much a day. Having some more fruits & veggies, less sodium, less fast food/fat food like potatoes. Check the calories! A daily intake should be around 1,400 or 2,200. More than that is unhealthy.

I'm a 5'1, growing 12/13 year old. I've been around 120 and at max 140, only when I eat a lot. Ever since I was 10/11. I haven't been gaining weight and don't really have depression, besides being mistaken for a girl, which is annoying. I am although going through puberty, and growing a bit each day. Should I change my diet, or just wait it out and wait for weight to distribute? Not really worried, just interested.
