Nearly all Mongolian women deficient in vitamin D, according to study

Posted on: October 4, 2013   by  Vitamin D Council

New research published in the Journal of Steroid Biochemistry and Molecular Biology has found that nearly all women in reproductive age in Mongolia are not getting enough vitamin D.

Getting the right amount of nutrients during reproductive age is important. During pregnancy, nutrients are important for the unborn child, their development and their risk of developing diseases later in life.

In past studies, researchers have found a high prevalence of vitamin D deficiency in the Mongolian population, particularly in children. Mongolia is far away from the equator and doesn’t get very many intense sunrays. In consequence, Mongolians are not able to make much vitamin D.

In the present study, 420 women between the ages of 18 and 44 were recruited for anthropometric, lifestyle and serum vitamin D measurements.

The researchers found that 99% of the women were vitamin D deficient (<20 ng/ml) and only one woman had a sufficient level (>30 ng/ml). They also found that throughout the year, only four months (March – July) produced adequate, synthesizable sunlight, meaning intense enough sunlight to help your body make vitamin D.

Researchers also found that higher educational status correlated with higher supplementation of vitamin D. However, no further correlations were found for other demographic, lifestyle, and anthropometric data.

The researchers concluded that dietary fortification and supplementation is crucial for Mongolian women of reproductive age, children, and all of the nation’s population.

3 Responses to Nearly all Mongolian women deficient in vitamin D, according to study

  1. Rita and Misty

    From the above article:

    “In the present study, 420 women between the ages of 18 and 44 were recruited for anthropometric, lifestyle and serum vitamin D measurements.

    The researchers found that 99% of the women were vitamin D deficient (30 ng/ml)”

    So, my question is: What is the rate of autism in Mongolia?

  2. Rita and Misty

    If the rate of autism isn’t extraordinarily high in Mongolia, I would then ask the following questions:

    *What is the median 25(OH)D level of newborns in Mongolia?
    *What percentage of these births develop into neurotypical children, and what are their typical 25(OH)D levels?
    *What percentage of these births develop ASD tendencies, and what are their typical 25(OH)D levels?
    *What is percentage of diseased placenta births in neurotypical population versus ASD population?

    What else would you ask?

  3. Rita and Misty

    Also–any correlation between 25(OH)D and diseased placenta…
