How do race and vitamin D levels affect the risk of having a preterm baby?

In a previous blog we summarized the main results from a published GrassrootsHealth study showing a 62% lower risk of preterm birth for women with vitamin D levels at or above 40 ng/ml (100 nmol/L) compared to women with levels less than 20 ng/ml (50 nmol/L). In this blog we will look at another analysis from that paper which assessed the association between vitamin D and preterm birth risk for white and non-white women. This was important to look at due to the racial and ethnic differences in preterm birth rates, with African American women having higher rates compared to other groups.

Among the women in the study (N=1,064), 10% of white women and 15% of non-white women had a preterm birth. African American women accounted for a majority (69%) of the non-white births and had a 19% preterm birth rate. For those with vitamin D levels at or above 40 ng/ml compared to women with levels less than 20 ng/ml, there was a 65% lower risk of preterm birth among white women (p=0.03) and a 68% lower risk among non-white women (p=0.008). The similar decreased risk suggests that improvements in vitamin D status may decrease the disparity in preterm birth rates between racial/ethnic groups.

Among women whose initial vitamin D level was less than 40 ng/ml, the preterm birth rate was 38% lower among white women (p=0.33) and 78% lower among non-white women (p=0.01) for those who raised their level to at least 40 ng/ml prior to giving birth vs. those who did not. This indicates that improving the vitamin D status of non-white women, who are more likely to have low vitamin D levels, could dramatically decrease racial disparities in preterm birth rates.

What Does it Take YOU to Get Your D to 40 ng/ml (100 nmol/L)?

Did you know your health could be greatly affected by making sure you have a vitamin D level of at least 40 ng/ml (100 nmol/L)? Help us help you.

STEP 1 – Do you know what your vitamin D level is? If not, be sure to test today to find out.

STEP 2 – Determine your target level. Are you at your target level? Experts recommend a level of at least 40-60 ng/ml (100-150 nmol/L).

STEP 3 – Need to boost your level? Use the D*calculator to see how much vitamin D it may take to reach your target. Opt for the Loading Dose for a quicker boost.

STEP 4 – Optimize how your body absorbs and utilizes vitamin D with co-nutrients and these simple steps.

STEP 5 – Re-Test! This is an important step to make sure you have reached your target level, and to ensure you are not taking too much! Re-testing after 3-4 months is recommended.

STEP 6 – Adjust, Repeat…

Give your immune system the nutrients it needs to support a healthy you and protect yourself from unnecessary diseases, especially COVID-19.

NEWS ALERT

The first Randomized Controlled Trial on vitamin D and COVID-19 has shown a 96% lower risk of ICU admission for those receiving vitamin D (as 25(OH)D to quickly boost vitamin D blood levels) along with the standard treatment, compared to those receiving standard treatment alone.

These results support many previous observational studies showing a relationship between vitamin D levels and intake and COVID-19 severity.

Review the Latest Nutrient Research for COVID-19

GrassrootsHealth Nutrient Research Institute has launched the new Immune Boost project with the use of our myData-myAnswers nutrient health system that nearly 15,000 people are already using for their health. Specific markers that influence immune health are suggested for testing as part of this project including:

  • Vitamin D
  • Omega-3 Index
  • Essential elements magnesium, selenium, and zinc
  • hsCRP

Our goal is to demonstrate how one can use the Nutrient Research Model established by Dr. Robert Heaney to show the effect of vitamin D serum levels of at least 40 ng/ml (100 nmol/L) on risk reduction for all ethnicities in the population. Status and intake of other nutrients will also be analyzed for any type of relationship to immune status and symptom severity. Join the project today!
