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.

im 5'1 5'2 and 96 lbs i think it may be a bad weight for my age because of what i looked up it said the average weight for a 13 year old is 145 lbs to witch im not even close, i have started to improve my eating habits but becauses its not helping i think it may be because of my lack of sleep, could this be a reason?

@Claire
There are lots of ways to to lose weight.
1. Try pea protien
2. Weight loss subliminals.
3. If you are soft, Try carb cycling and HIIT cardios 3 times a week.
4. Take contrasting showers.
5. Sleep enough
6. Try the breath diet.
7. For endomorphs, Metabolic confusion works best.
And last one, Try massages.
(This does not subsitue any medical help you have been reciving. I to not promote any types of eating disorders.) I hope this can help alot of people.

IM 5'4 AGE 15 WEIGH 140.2 AM I FAT. I NEED SO HELP DETERMINING THAT BECUASE I THINK I LOOK FAT. if ANY BODY could HELP ME GET SOME HEALTHY FOOD CHOICES THAT WOULD BE GREAT.

Muscle weighs more than fat so you could have muscle. Or you could have some fat too. The main thing is not to starve yourself or think, oh i need to loose weight so I won't eat. Well this can actually have you gain weight because your body goes into starvation mode and starts piling up fat. so don't do that. I would cut back on your sugar intake slowly. Like if you eat 2 scoops of ice cream every night cut down to 1 and just slowly decrease sugar intake. Maybe start reading nutritiion facts on food items before you eat them. Also, you can follow a free diet plan online. Just remember don't do a diet plan that has you loosing more than 4 pounds a week because that is not healthy. I know this is a lot of info and I hope it helps. :)

Hey I'm Destiny and I'm 13 years old and I weigh 132 and my height is 5'11 1/2 and my tummy is flat but my bottom is thick and I play sports and I'm in the marching band (how is this possible??)

it depends if this is muscle or fat. It could be muscle because you march and I'm guessing you do squats with your sports. I think that you should be fine. It is most likely muscle which is a good thing. :)

Hey don't feel bad about being under wait. We can make it better!! :) I would eat a lot of protein and good fats. I know it sounds weird but I would do workouts that build muscle. If you do that your body will start needing those calories and you will gain wait from the muscle as well. Also, if you have a local Smoothie King near you, they have high protein smoothies that will help with wait gain. Don't feel bad about your wait. At least all you have to do is gain wait, I have to lose it! hahahaha!

I am 13 and 5/5'1. Ever since the covid19 quarentine, I have been gaining weight. I am 61 kg, but I want to lose weight without the hassle of keeping up with working out and never actually finishing what I started. My goal is to be in between 43 to 45 kg. If anyone older could lend any food tips, please answer this. Thx!
