Pregnant women with low levels of vitamin D may be more likely to suffer from bacterial vaginosis (BV) - a common vaginal infection that increases a woman's risk for preterm delivery, according to a University of Pittsburgh study.
Available online and published in the June issue of the Journal of Nutrition, the study may explain why African-American women, who often lack adequate vitamin D, are three times more likely than white women to develop BV.
"Bacterial vaginosis affects nearly one in three reproductive-aged women, so there is great need to understand how it can be prevented," said Lisa M. Bodnar, Ph.D., M.P.H., R.D., assistant professor of epidemiology, obstetrics and gynecology, University of Pittsburgh. "It is not only associated with a number of gynecologic conditions, but also may contribute to premature delivery - the leading cause of neonatal mortality - making it of particular concern to pregnant women."
The study, which included 469 pregnant women, sought to determine whether poor vitamin D status played a role in predisposing women, especially African-Americans, to BV. Dr. Bodnar and colleagues at Magee-Womens Research Institute found that 41 percent of the study participants had BV and of these, 93 percent had insufficient levels of vitamin D. They also found that the prevalence of BV decreased as vitamin D levels rose.
