Socioeconomic and environmental risk factors of bacterial vaginosis in early pregnancy.
The main aim of this prospective study was to determine the socioeconomic, demographic and environmental factors that may be associated with the occurrence of bacterial vaginosis at early pregnancy in an indigent population from Central Poland. A group of 196 pregnant women was selected randomly from the patients of 10 district maternity units in the Lodz region, Central Poland. Only singleton pregnancies between 8 and 16 week of gestation were qualified for inclusion in the survey. A standard questionnaire covering medical, socioeconomic, demographic, constitutional and environmental items was administered to every subject and was verified with medical records. Cervico-vaginal swabs were collected from the women under study and tested for bacterial vaginosis (BV) according to Spiegel's criteria. Based on the results of Gram stain, BV was diagnosed in 51 women (28.5%), grade I microflora among 66 (36.9%) and grade II among 62 women (34.6%). In the univariate analysis, only single marital status proved to be an important risk factor associated with BV during pregnancy, this was confirmed in the multivariate analysis. Pregnant women who present risk factors for abnormal cervico-vaginal microflora should be covered by comprehensive prenatal surveillance, which enables early detection and treatment of this pathology. Research that identifies the causal pathways and mechanisms through which social disadvantage leads to a higher risk of preterm birth may help to reduce current socioeconomic and demographic disparities and improve pregnancy outcome.
