Vitamin D Levels In Pregnancy Linked with Child IQ – Study

Vitamin D is a critical nutrient and has many important functions in the body. A mother’s vitamin D supply is passed to her baby in utero and helps regulate processes including brain development. A study published today in The Journal of Nutrition showed that mothers’ vitamin D levels during pregnancy were associated with their children’s IQ, suggesting that higher vitamin D levels in pregnancy may lead to greater childhood IQ scores. The study also identified significantly lower levels of vitamin D levels among Black pregnant women.

Melissa Melough, the lead author of the study and research scientist in the Department of Child Health, Behavior, and Development at Seattle Children’s Research Institute, says vitamin D deficiency is common among the general population as well as pregnant women, but notes that Black women are at greater risk. Melough says she hopes the study will help health care providers address disparities among women of color and those who are at higher risk for vitamin D deficiency.

Low Vitamin D may raise bladder cancer risk – Study

Vitamin D deficiency is associated with an increased risk of developing bladder cancer, according to a systematic review of seven studies led at the University of Warwick.

Five out of the seven studies linked low vitamin D levels to an increased risk of bladder cancer.

The researchers then looked at the cells that line the bladder, known as transitional epithelial cells, and found that these cells are able to activate and respond to vitamin D, which in turn can stimulate an immune response.

This is important because the immune system may have a role in cancer prevention by identifying abnormal cells before they develop into cancer. Lead author of the study Dr. Rosemary Bland said, “More clinical studies are required to test this association, but our work suggests that low levels of vitamin D in the blood may prevent the cells within the bladder from stimulating an adequate response to abnormal cells.
