Study shows vitamin D deficiency is nearly universal in mothers and newborns in Turkey

Posted on: May 28, 2014   by  Vitamin D Council


In a new study published in Journal of Maternal-Fetal & Neonatal Medicine researchers found that severe vitamin D deficiency is very common in pregnant women and their newborns.

Vitamin D deficiency is a major health problem in certain countries with an abundance of sunlight. These countries, such as Turkey and Iran, are experiencing high rates of vitamin D deficiency due to increased time spent indoors and cultural and religious reasons, such as over-garments, that cover most of the skin.

Deficiency among pregnant women is especially serious as they need a higher vitamin D intake to maintain healthy levels for both themselves and their developing babies.

Recently, researchers measured the vitamin D levels among pregnant women and their newborns in Turkey to determine the prevalence of vitamin D deficiency and bring attention to this demographic.

They recruited 97 pregnant women for the study. The mothers’ vitamin D levels were assessed and blood samples from the umbilical cord taken after birth were used to measure the vitamin D levels of the newborns.

The researchers found that only two women had vitamin D levels above 20 ng/ml. Overall, the average vitamin D levels for the mothers and newborns was 4.97 ng/ml and 4.29 ng/ml, respectively.

“Severe vitamin D deficiency is common in reproductive women and their newborns in [low socio-economic status] cities of Turkey,” the researchers concluded.

The research team calls for vitamin D supplementation campaigns to target pregnant women and their newborns in high risk areas.

    If anyone is wondering how someone can be so daff as to blow themselves up with a bomb strapped around their waist…

    Women wearing burkas or other all-covering clothes, hiding in their homes unable to get sunshine or proper food, hiding from harm, give birth to and rear children who are not normal. We see our own all-American women doing it and they don’t even wear burkas.
