Abstract

Many people are now interested in the importance of vitamin D because it does more than just help regulate calcium levels. More and more studies are being done to understand how vitamin D during pregnancy supports various aspects of health, as well as the consequences of not having enough of it. The goal of this research is to find out how common vitamin D deficiency is among pregnant women and the effects it has on both the mother and the baby.


Patients and Methods: 200 women who were about to give birth were chosen to participate in a study while they were in the hospital. We gathered information about the health of all the participants from their medical records. They also kept track of when the babies were born and what happened during delivery. A blood test that measures how much vitamin D is in the body. The enzyme-linked immunosorbent assay is a test that uses enzymes to find and measure things in the body, like antibodies or antigens.


Results: Out of all the cases, 9 had a good level of vitamin D, 20 had a bit of a low level, and 171 had a very low level. The groups had similar information about the people's characteristics and reproductive history, and the differences between the groups were not significant. There were no significant differences in vitamin D levels among those who had higher body weight, gestational diabetes, pre-eclampsia, and growth problems in the baby in the womb. But, women who did not have enough vitamin D were more likely to have high blood pressure during pregnancy. There were not many differences in how babies were born and how they did soon after birth for women with different amounts of vitamin D.


Conclusion: Not having enough vitamin D is a common health problem in pregnant women in Iraq and is called hypovitaminosis D. When a woman is pregnant and has low weight, there is a greater possibility that she may develop gestational hypertension, which is a negative condition. 25(OH)D is a type of vitamin D that is checked in the blood.
