Low vitamin D levels could increase the risk for gestational diabetes in pregnant women, according to a study from the University of Washington School of Public Health. Maternal blood vitamin D levels were measured at 16 weeks gestation in a group of 135 pregnant women with gestational diabetes and 517 healthy pregnant women. Results showed that the pregnant women with diabetes had lower vitamin D levels compared to healthy controls. Women in the lowest quartile for vitamin D levels were twice as likely to have gestational diabetes compared with women in the highest quartile. The researchers conclude that, “…early pregnancy vitamin D status…is inversely associated with gestational diabetes.”
