Any idea how to calculate a child's BMI?

[Yurtgirl]

A body mass indez that is

The reccomended too thin, healthy and obese figures are different for children

My ds is soooooo skinny I am beginning to worry

Presume it's the same for an adult as a child. Go to google and put in BMI calculator. As long as you know your DS's hieght and weight it'll tell you
HTH and try not to worry about DS

You work it out the same way as an adult but the limits are different.

Have a look at this

Neicie - Thanks for that, that chart was so much better than the one I found

It seems that my skinny ds is actually at the higher end of the weight range for his height, even though he is mega skinny and you can see his ribs. If he gains 3kg he will be at risk! If he looses 5kg he will be officially underweight (only just)

Goodness knows where he would loose it from, he is so skinny

Yurt both of my Ds's are skinny.. underweight and have low BMI's.. GP is very happy with them and their weight as they are extremely active and eat like horses.. so burn everything off.

So I would say if your DS is active , eats well and is a happy chappie .. don't worry too much.. if you are worried pop along to the GP and I'm sure they will reasure you.

seeing ribs is supposed to be normal, or so I remember reading on some website onetime
prob is, we never see it on kids these days so it looks skinny to us.

sorry, rubyrioja, didn't read your post properly. I was replying to yurtgirl really, to reassure her that her ds is not too skinny just cos can see ribs. I agree with you about the overweight/no ribs visible

hmm wii fit told me that my daughter was 'normal' this is the same daughter who struggles to eat a proper meal and at 4 years old only weighs two stone. i ignored i have already been told by docs that she is underweight

height and weight for children is done using a centile chart please dont use an adult bmi calculation this will give you completly wrong figures and a healthy bmi for adults is 20-25 this varies depending on a childs age if under 5 contact your hv if they are over 5 contact your school nurse (takes over childs health once they start school) and ask their advice and get them to weigh and measure your child.
