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.

No definetly not. You are probably on the slender side. I workout minimally wit( a slightly healthy diet) i am 4’9 and 89 pounds. This says I’m not overweight and so does my doctor but I look terrible. Even my freinds don’t believe my weoght so I had to show them myself on the scale to prove it (I swear they are good friends, they didn’t make me. I just wanted to prove it) my thhighs are gaint and I have nice chance for a bright gap even if I wanted one. I think my hips are too narrow for that. My face, legs and stomach collect all of my fat, where my chest is flat, my arms are noodles and my fingers are bony. I hate how disproportions I am. Kids st schoo jokingly call me pudgy and say I’m squishy it’s fine but it makes me so mad at i do rescrict my diet a little and at least excerscise a little when my friends don’t and look thin.

Please give me some advice because I cannot go outside because my parents won't allow me so please help me and I cannot do inside activities because my house is to small so please help me.

Well, it all depends on muscle mass and a whole lot of other biological factors. So you may be, or you may not be. Hope this helps.

I'm 5'1 and 128 lbs but I workout a lot so idk what to do

Well, working out isn't the only thing you have to do in order to lose weight. It's simple! Dieting. Exercising wouldn't be needed to lose weight if you diet, too. It's only there to lose minor calories. Remember, dieting is 80% of how you lose weight. Excerising is the other 20%.

10.5/4’11/136 pounds boy. Am I morbidly obese

Very.
I am a thirteen year old girl who's around 5'4~5'5 and 136 pounds would lead up to me being overweight. Let alone a ten year old, who's 4'11.
