Child IQ is affected by Vitamin D during Pregnancy – The Journal of Nutrition

Vitamin D has many essential roles in your body and is a vital nutrient. The vitamin D of your mother is transmitted to your child at uterus and aids in the regulation of processes and the growth of your brain. In a November 2, 2020 study published in The Journal of Nutrition, vitamin D levels of mothers during pregnancy were related to their child IQ, indicating the likelihood of higher vitamin D levels during pregnancy contributing to higher infancy IQ scores. The study found that the levels of Vitamin D of Black pregnant women were also substantially lower.

The lead author of the Dept. of Child Health, Conduct, and Growth study at the Seattle Children’s Research Institute, Melissa Melough, said that vitamin D deficiency is widespread in both the general population and pregnant women. Melough hopes that the research will lead to health professionals discussing the inequalities between women of colour and those at a higher risk of vitamin D deficiency.

“The melanin pigment protects the skin control lesions from light, but melanin also decreases the production of vitamin D in the skin by blocking UV rays. As a result, we were not shocked that Black pregnant women in our sample experienced a high deficiency of vitamin D.

Although several women who are pregnant are taking a prenatal vitamin, a current deficiency of vitamin D may not be reversed. “I hope our work will raise understanding of this issue and illustrate long-term effects for the infant and neurocognitive production of prenatal vitamin D, and highlight the need for some suppliers of groups to pay closer attention. Generally, wide-ranging tests of vitamin D levels are not recommended, but I think health professionals need to search for the most dangerous, like Black women.

Addressing inequality

In the US, as many as 80% of Black pregnant women may be insufficient with vitamin D, according to Melough. Some 46 per cent of moms who participated in the study had vitamin D deficiencies during their pregnancy, and Black women had a lower level of vitamin D compared with White women.

The data from the cohort in Tennessee named CANDLE (Conditional Early Childhood Development and Learning Conditions) were used by Melough and her co-authors. Starting in 2006 the CANDLE scientists recruited pregnant women and collected information on the health and growth of their children over time.

Higher vitamin D values in pregnancy were associated with higher IQ in children aged 4 to 6 years after testing for many other IQ-related factors. Although observer studies such as this can not demonstrate the cause, Melough claims that her results have significant effects and warrant further study.

Deficiency in vitamin D

Melough said, “The deficiency of vitamin D is fairly general. “There is a reasonably straightforward solution to the good news. Adequate vitamin D can not be obtained by diet, and not everyone can make up for this difference by sun exposure, so taking a supplement is a safe option.

600 International Units (IUs) are the minimum daily intake of vitamin D. Americans eat on average less than 200 IU in their diet, and if people are not shielded by sun exposure or supplementation, Melough says people are likely to be bad. Like fatty fish, eggs and fortified sources, such as cow milk and breakfast cereals, foods that have higher vitamin D concentrations. Melough states, however, that vitamin D is one of the toughest nutrients to get enough of our diets.

Further investigations are required to evaluate optimum levels of vitamin D in pregnancy, but Melough expects this research to help establish dietary guidance for pregnant women. Nutritional supplementation and detection can be an impactful strategy for reducing health inequalities, particularly in Black women and those at high risk of vitamin D deficiency.

Key Takeaways

Melough says the analysis has three primary takeaways:

  • During pregnancy, vitamin D deficiency is normal and Black women are more likely because the melanin pigment in the skin decreases vitamin D development.
  • Higher levels of vitamin D can stimulate brain development and lead to increased IQ scores in mothers during pregnancy
  • Screening and nutrient supplements can correct vitamin D deficiencies in high-risk individuals and encourage cognitive function in children

“I want people to know that it’s a common issue and that it can impact the growth of children,” said Melough. “Deficiency of vitamin D may occur even if you eat a good diet. It’s also attributed to our diets, skin pigmentation or other external factors.
