Vitamin D and Pregnancy: Camden Study

Pregnancy Clinical Trial

Official title:
Vitamin D Status in Pregnant Women

Clinical Trial Summary

Vitamin D is present in food either naturally or by fortification and included in nutritional supplements. It is also synthesized photochemically by the skin from ultraviolet B radiation. Vitamin D synthesis varies by season and with latitude as well as according to intensity of skin pigmentation. Recent research in the United States found lower circulating levels of 25 (OH) D, the primary indicator of vitamin D status, among minority women who were either pregnant or in their reproductive years. The extent to which maternal vitamin D has an influence on the course and outcome of human pregnancy remains to be more completely studied. We propose to use the HPLC method to assay cholecaliferol (vitamin D3) and ergocalciferol (vitamin D2) to assess maternal vitamin D status. This will be accomplished by analyzing existing fasting samples and data derived from the 2001-2006 cohort (N=1141) of young, low income minority gravidae from Camden, New Jersey to determine:

1. The prognostic importance of maternal vitamin D status for birth weight, gestation duration and poor pregnancy outcomes (low birth weight, preterm delivery, fetal growth restriction).

2. The relation of maternal vitamin D status to important complications of pregnancy (gestational diabetes and pre-eclampsia).

3. The relationship of maternal vitamin D status to maternal diet and supplement use, season of year, ethnicity, overweight/obesity, and other maternal characteristics.
