Bacterial Vaginosis, Educational Level of Pregnant Women, and Preterm Birth: A Case-Control Study

Abstract

Objective. In a prospective study, we have recruited two groups of pregnant women (the first one with preterm labor activity; the second one with labor in term), trying to find a correlation between bacterial vaginosis (BV) and preterm birth activity. Other parameters influencing the presence of BV have been studied as well, such as educational level and history of previous preterm deliveries. Materials and Methods. Each group was composed of 75 women; recruitment stopped when the number was reached. Bacteriological data were retrospectively collected from the follow-up visits that pregnant women had performed at the regional hospital facility, where the study was performed. The diagnosis of BV was made according to Amsel criteria. Results. Our study showed a significant correlation between BV and preterm labor. BV seems to be an independent risk factor for preterm labor. In the study group, the prevalence of BV was 32%, whereas in the control group, the figure was 14.6% (). Conclusion. Highly risked groups for a preterm birth activity, such as pregnant women presenting BV and with a low educational level, have to be followed up and eventually treated cautiously in order to avoid early and late complications of preterm delivery.
