The Factor Increasing The Risk Of Premature Birth – Part 2 of 3
A baby is considered premature when born before 37 weeks of pregnancy, according to the March of Dimes. Early birth can cause a number of problems, including issues in the lungs, brain, eyes, ears, and the digestive and insusceptible systems, according to the March of Dimes. Previous studies on vitamin D levels and their effects on early delivery have been mixed. “One or two extensive studies showed vitamin D deficiency increased the risk. However, smaller studies found no link.
Vitamin D levels vary depending on the season, with low levels more appropriate in winter. Levels also vary depending on where a person lives. Black women are more likely to be deficient in vitamin D than other groups. For the new study, researchers looked at just over 2100 women who didn’t give lineage early, and more than 1100 who delivered preterm. All of the women included in the research had given birth to single infants between 1999 and 2010.
The researchers found that as the women’s blood levels of vitamin D decreased, the bet of preterm birth increased. There is no universally agreed upon definition of deficient vitamin D levels. In general, according to the NIH, levels below 30 nmol/L (nanomoles per liter) are too offensive for good health, while levels of 50 nmol/L are probably sufficient for most people. In the study, Bodnar and her colleagues grouped women as less than 50 nmol/L, 50 to 74,9 nmol/L, and 75 nmol/L or above.
