Insights
Bacterial vaginosis (BV) is a significant risk factor for preterm birth and low birth weight (LBW), particularly in pregnant Black women. Treating BV can effectively reduce these adverse pregnancy outcomes.
Area of Science:
- Obstetrics and Gynecology
- Maternal-Fetal Medicine
- Infectious Diseases in Pregnancy
Background:
- Preterm low birth weight (LBW) is a leading cause of infant morbidity and mortality.
- Bacterial vaginosis (BV) is increasingly recognized as a potential contributor to adverse pregnancy outcomes.
- Pregnant Black women exhibit a disproportionately higher prevalence of BV compared to pregnant White women.
Purpose of the Study:
- To review existing literature and establish bacterial vaginosis (BV) as an independent risk factor for preterm birth and low birth weight (LBW).
- To highlight the increased risk of BV and its consequences in pregnant Black women.
- To evaluate the efficacy of BV treatment in reducing rates of preterm birth and LBW.
Main Methods:
- Systematic review of published literature on bacterial vaginosis (BV) and its association with preterm birth and low birth weight (LBW).
- Analysis of epidemiological data regarding BV prevalence in different racial groups.
- Review of studies investigating the effectiveness of BV treatment during pregnancy.
Main Results:
- Bacterial vaginosis (BV) is confirmed as an independent risk factor for preterm birth and low birth weight (LBW).
- Pregnant Black women have a nearly threefold higher prevalence of BV compared to pregnant White women.
- A significant proportion of women with BV are asymptomatic, underscoring the need for screening.
- Treatment of BV during pregnancy has demonstrated effectiveness in reducing preterm birth and LBW rates.
Conclusions:
- Bacterial vaginosis (BV) is a modifiable risk factor for preterm birth and low birth weight (LBW).
- Targeted screening and treatment of BV in pregnant women, especially Black women, can significantly improve perinatal outcomes.
- Integration of BV screening into routine antenatal care is warranted to mitigate risks associated with preterm birth and LBW.
Abstract:
Preterm low birth weight is the major determinant of infant morbidity and mortality. Numerous studies have linked bacterial vaginosis (BV) with preterm birth and low birth weight (LBW), especially among black women. This article reviews the published literature to provide clear evidence that BV is an independent risk factor for preterm birth and LBW. Pregnant black women are especially at risk, having nearly three times the level of BV as pregnant white women. Compounding the problem is the fact that half the population of women with BV are asymptomatic, and current standard antenatal procedures do not provide for screening for BV. By reviewing BV treatment literature, this article also provides evidence that treatment for BV is effective and that the identification and treatment of BV in pregnant women can lead to substantial reduction in the high rates of preterm birth and LBW.
