Vitamin D and pediatric bone health

Posted on: May 7, 2013   by  John Cannell, MD


I have written about low bone mineral density in infants and the high incidence of probable intrauterine rickets before.

New study finds high prevalence of osteopenia in infants. Posted on October 26, 2011 by John Cannell, MD.

I also reported on a prospective cohort study of vitamin D and stress fractures in adolescents.

    Greetings Dr. Cannell and VDC members,

    Just a few comments on the excellent article posted above:

    As taken from Dr. Cannell’s article:

    “In two studies of forearm fractures of African American children in Washington D.C, 59% were vitamin D deficient (<20 ng/ml); the majority (58%) of forearm fractures resulted from minor trauma, and 25(OH)D levels were slightly but significantly (47% vs. 41%) more likely to be deficient (< 20 ng/ml) in children with fractures.”

    According to reports by the United States Center for Disease Control and Prevention, African American suffer greatly from chronic diseases such as cancer, heart disease, fibromyalgia, lupus, and obesity which can be effectively controlled or prevented with vitamin D supplementation.

    And it also appears to me that Black children suffer from higher rates of rickets and autism….

    But, despite the alarming health situation for African Americans, conventional medical practitioners do not seem to be informing them that they may need to take at least 5,000 IU of vitamin D3, in supplement form, every day; and that Black children should also be given adequate amounts of vitamin D3 on a daily basis, because food and drinks do not supply adequate amounts of vitamin D.

    I wonder what it will take to turn the tide on this silent public health issue.
    This is truly frustrating for me….

    Dr. Cannell, your mountain pool analogy regarding vitamin d is superb:

    “Think of vitamin D as contained in a mountain lake with streams and pools beneath the lake. Only if the ‘maintain serum calcium and the bone reservoir of calcium’ uppermost lake is full does vitamin D flow over to fill up lower pools, such as the ‘prevent autoimmune diseases’ pool lower down on the mountain.”

    I feel I must always state that I’m not a physician, nor am I a scientific researcher. I’m simply someone who cares about my health and well-being; and therefore, nutritional research holds the utmost interest to me…it is an all-consuming hobby for me, really.

    From what I’ve read, I tend to think that vitamin D is the master hormone; in other words, the wellspring from which all good health flows.

    I hope my lack of scientific terminology may be forgiven here…plainly speaking, (and only in my opinion) the more chronic health conditions under which a person is suffering, the higher amount of vitamin d s/he will need to take in order to be healthy.

    It’s my dream to see two things accomplished in my lifetime:

    1. To have mainstream medicine conclude that sufficient 25(OH)D level commences at 40 ng/ml.
    2. To have the 25(OH)D test made a standard request within mainstream medicine.

    I’d love to see these two things accomplished within the next 50 years.

    To your good health,
    Pollyanna 🙂
