Re: RSS/SGA Growth Chart CD - UK vs US Girls head circumference

[Guest guest]

Can I just say how fantastic the growth chart CD is - particlarly the BMI

calculation and RSS length curve (I now know Maddy has been increasing BMI

slowly since birth and is exactly on the RSS girls line.)

However - I'm slightly confused by her head circumference measurement. On the

UK child health charts that everyone gets here she has been following the 50th

percentile exactly since birth. On the magic charts (and the US standard head

circumference charts I've checked) her head circumference has been moving

quickly from 50th to 90th percentile over the last 9 months. The graphs are

definitely different - even at 12 months the 50th percentile for US is 45cm and

for UK is 46.4cm.

When we go to get this measured the Dr measures around the widest point. Is this

different in the US? - I can't believe we have that much extra brains from you

guys!!!

Thank you for the complement! Katy and I worked with another RSS

mom and the physician who created the original CDs to come up with

what we think is a pretty darn useful tool.

For those of you who don't know what she is talking about, it is a

CD of growth charts, divided by gender and age, that you can enter

your child's measurements into a chart on an ongoing basis, and it

automatically charts weight, length and head circumference for Bith-

3yrs and then weight, length and BMI for age 2-20 (once your child

is measured STANDING). For stature, it also plots the RSS stature

mean for untreated RSS children (from the Wollman data) right on the

same chart as your child's data -- so it has your child's curve, the

normal US curves, and the RSS curve, all charted for you.

Totally awesome.

This is free to any member of MAGIC, so just call 1-800-3MAGIC3.

They may ask you to pay postage for the DVD, I don't know, but it

can't be that much.

But re the head circumference question, hmmmm. I have NO idea.

I was going to compare the CD to the hard copy charts, but you said

you did that already. So what you are saying is that the US charts

and the UK charts are different. Hmmm..... The only thing I can

think of is that several years ago, the US revised their growth

charts, because the original growth data was on a very small group

of mostly caucasian children from a relatively privileged city in

Ohio. Not the best " mean " for the entire US. Maybe the head

circumf. changed, and the UK charts are from the old ones??? The

only explanation I can think of right now. Hmmmm, very interesting

question.
