    @chowder130 Hey, good question...It is a specific equation based on anthropomorphic data colloected through various research studies with the goal to...for lack opf a better analogy...turn a 2 dimensional diagram into 3 dimensional data.

    Wait, why 703? Why not 15 or 24? WHy that one in specific?

    @DrPatrickKrupka I just did some reading and it appears that, as I have experienced, the bioimpedance machines have trouble with accuracy in people far outside the 'norm' in terms of body comp. I have always been lean and for some reason highly resistive to electricity. I consistently get told that I am like 20+% bodyfat by machines, when caliper tests are in the 11-13% range. Have you run into any similar situations? Obviously I have never used an RJL machine, so perhaps that is different.

    @DrPatrickKrupka Wow, the RJL systems are expensive! I just read the descriptions and they seem really neat!

    @DrPatrickKrupka Sure, or have one qualified examiner that goes from school to school and uses one of those nifty calipers that does auto-pressure. If you're doing it like 3 times per year then there's no reason one person couldn't handle quite a number of schools.
    I always wondered about the bioimpedance, the handheld models never seem to work well on me. I looked for RJL and the seem to be better than that, but how accurate are they in your opinion compared to other methods?

    @slizzardman You're right that caliper testing would probably yeild better results than BMI for an effort like this, but if you want to avoid intra-examiner reliability issues, a machine like a bioimpedence machine would probably give more reliable results. In my office I use one from RJL Industries that provides 3 compartment analysis...1. Lean mass, 2. Fat mass, 3. Extracellular mass.

    @DrPatrickKrupka I know... *cries* :P
    It's hard to get government to do it right for cheap when they can do it wrong for free...

    @slizzardman Unfortunately, I think that the government is using BMI in these programs because it's low-tech, and requires almost zero training and extra equipment. What's sad is that it's so inaccurate that the programs will largely be wasted money.

    I think that obesity report cards are brilliant, but BMI is the absolute worst way to do that. I'm considered overweight by BMI and I'm like 10% body fat! Ridiculous.
    I always thought BMI was the absolute dumbest thing. A simple 3 site or even the 1 site super-iliac test would be way better.

    I think if they were to hire a functional nutrition specialist for a school, this would be realistic and somthing that they should do. They would obviously go much further than the BMI report card like you do.

    I dont think they should mandate somthing like this, but it is a positive idea in the least sense. If a school has the resources to hire someone like that, then they should consider it.

    This person could also help the cafeteria serve better food than the trash in most public schools

    @taborsmith1 Thanks Tabor, I hope this trend doesn't "take off"...I fear this will be another well-intentioned but worthless layer of bureaucratic busywork that our teachers have to deal with. I really think that % body fat measured in the doctor's office is much more productive (providing that the doctor understands health, and not just drug dispensing)

    Thanks Dr. Krupka, I didn't know that.. I totally agree with you.

  • DrPatrickKrupka

    @FunctionalWellness Yes they are...and I think you'll see more of it in the future. I agree that our kids need help, but I think th eparents and the doctors should be the ones to do it. Now, how do we get the parents and doctors ready for this task?? THAT I'm still trying to work on.
