Low levels of vitamin D linked to common vaginal infection in pregnant women

26.05.2009
Findings may explain higher rates of infection among African-Americans

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.

Vitamin D may play a role in BV by regulating the production and function of antimicrobial molecules, which in turn may help the immune system prevent and control bacterial infection. However, only about one in four Americans gets enough vitamin D. Vitamin D deficiency may be more common in African-Americans because dark pigmentation limits the amount of vitamin D that can be made in the skin through casual exposure to sunlight. African-American women also are less likely to meet dietary recommendations of vitamin D.

"Although this is a preliminary study, it points out an interesting connection between vitamin D and BV," said Dr. Bodnar. "We don't recommend pregnant women take mega-doses of vitamin D based on these findings, but they should talk with their doctor if they have concerns about their vitamin D status. All women should be encouraged to eat a healthy diet and take a prenatal vitamin before they become pregnant or as soon as they find out they are pregnant."

Co-authors of the study include Marijane A. Krohn, Ph.D., and Hyagriv N. Simhan, M.D., with the University of Pittsburgh and Magee-Womens Research Institute. The study was funded by the National Institutes of Health.

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
