    Body iron stores in relation to risk of type 2 diabetes in apparently healthy women.

    CONTEXT: Type 2 diabetes is a common manifestation of hemochromatosis, a disease of iron overload.
    However, it is not clear whether higher iron stores predict the development of type 2 diabetes in a
    healthy population. OBJECTIVE: To examine plasma ferritin concentration and the ratio of the
    concentrations of transferrin receptors to ferritin in relation to risk of type 2 diabetes. DESIGN,
    SETTING, AND PARTICIPANTS: Prospective nested case-control study within the Nurses' Health Study
    cohort. Of the 32 826 women who provided blood samples during 1989-1990 and were free of diagnosed
    diabetes, cardiovascular disease, and cancer, 698 developed diabetes during 10 years of follow-up.
    The controls (n = 716) were matched to cases on age, race, and fasting status; and on body mass
    index (BMI) for cases in the top BMI decile. MAIN OUTCOME MEASURE: Incident cases of type 2
    diabetes. RESULTS: Among cases, the mean (SD) concentration of ferritin was significantly higher
    (109 [105] vs 71.5 [68.7] ng/mL for controls; P<.001 for difference) and the mean (SD) ratio of
    transferrin receptors to ferritin was significantly lower (102 [205] vs 141
    [340], respectively; P =.01). In conditional logistic regression stratified on the matching factors
    and controlled for BMI and other diabetes risk factors, the multivariate relative risks [RRs]
    of incident type 2 diabetes across increasing quintiles of ferritin were 1.00, 1.09 (95%
    confidence interval [CI], .70-1.70), 1.26 (95% CI, 0.82-1.95), 1.30 (95% CI, 0.83-2.04), and
    2.68 (95% CI, 1.75-4.11) (P<.001 for trend). The RRs across increasing quintiles of transferrin
    receptors to ferritin ratio were 2.44 (95% CI, 1.61-3.71), 1.00 (95% CI, 0.64-1.56), 1.13 (95%
    CI, 0.73-1.74), 0.99 (95% CI, 0.64-1.53), and
    340.1 (A=.01 for trend). Further adjustment for an inflammatory marker (C-reactive protein) did not
    change the results appreciably. The associations persisted within strata defined by levels
    of BMI, menopausal status, alcohol consumption, and C-reactive protein. CONCLUSION: Higher
    iron stores (reflected by an elevated ferritin concentration and a lower ratio of
    transferrin receptors to ferritin) are associated with an increased risk of type 2 diabetes
    in healthy women independent of known diabetes risk factors.

    Hurrah - he's back !!

  5. I have no problem with your sig line at all. But it, and the web links to your pages reveals the
    religious motivation you have for your obsession for consuming iron and how you think it the root of
    all manner of human problems. Thus, to understand why you are obsessed by iron related research and
    why you take such umbrage and flame so easily those who clearly show the scientific part of your
    thesis to have no scientific basis, one can not ignore the reason for your sig line and why you push
    it and your links in all of your messages. Belive any religious idea you wish and post it when and
    where you wish, but don't deny the sig line and what it means to you and your religious thesis. Be
    prepared also to be confrounted by the distortions about Jesus it provides. We luv ya Tom.

    Jesus ate flesh, made it possible for those around him to do so more easily, did so in a religious
    context; killed animals, and consumed iron by the mouthful when he consumed ordinary foods that
    were not flesh. Other then that, my friend Tom, you are correct.

    I thought there was MORE to .. you .. than giving a fk about your fellow man ..

    You are somehow obsessed by my sig line ..

  7. Tom my friend, thank you for confirming once again in spades waht is easily to be seen. What you
    post is often not medical but biochemistry, which can apply to many animal life forms. Tom you have
    a specific religious thesis about the role of iron in human religious affairs, a personal revelation
    based on private interpretation of scripture mixed in with some equally views about humans should
    eat and why. All the articles you post is in support of that thesis. Your sig line is a comeon to
    get people convinced of your thesis and eating habits, by using a provokative statement about a
    religious figure. If the article you post, is not about iron, it is about the nutritional advantages
    of a veggie diet or animals as food sources; all tie into your thesis. What part of the above is in
    error Tom? What you post is .. NOT .. some innocent article you happen to run across and think folk
    might find it amusing. They are a cut and paste job, selected only if it supports your thesis, and
    ignoring any which is not; there is a name for that kind of behavior. We luvs ya Tom.
