What are the reasons why pregnant women lack VD?

1. Increased VD requirements during pregnancy

All the VD needed by the fetus is actively transferred from the pregnant mother through the embryo. Therefore, pregnant women must not only meet their own needs, but also provide the nutrients necessary for the development of the fetus, which is easy to cause VD deficiency. In order to take into account the fetal bone growth and development and the additional needs for calcium and VD, the VD requirement will increase by 4-5 times. Without sufficient VD supplementation, VD deficiency may increase.

2. Insufficient sunlight

Because more than 90% of the VD in the human body comes from the skin and is produced in the body through wind and sun exposure, insufficient sunlight exposure will cause insufficient increase in VD in pregnant women.

Most Chinese women, especially young women, are willing to avoid wind and sun exposure to maintain fair and tender skin.

Women in big cities are more likely to be indoor workers, get up early and go to bed late, and spend very little time outdoors. They are exposed to more smog pollution and insufficient sun exposure.

In addition, due to the relatively high altitude and short sunshine hours in North China, it is very easy for the region to suffer from insufficient wind and sunlight.

Weight-bearing winter clothing is thick, exposing less skin area, and the short sunshine hours and reduced outdoor time make it more likely to result in insufficient sun exposure.

Full-term Africans, such as those in my country, have thicker skin and produce less vitamin D through the skin.
