Abstract

 Bacterial vaginosis (BV) is a common genital tract disorder during pregnancy, often asymptomatic but associated with adverse outcomes such as preterm labour. This study aimed to determine the incidence of BV among women in preterm and term labour and analyze maternal and neonatal outcomes.
Materials and Methods: A prospective observational study was conducted on 120 pregnant women (60 preterm, 60 term labour) at Government General Hospital, Eluru (2024–2025). BV was diagnosed using Amsel’s criteria. Data were collected on vaginal pH, discharge, clue cells, whiff test, and high vaginal swab cultures. Maternal and neonatal outcomes were analyzed using SPSS v17.0.
Results: The incidence of BV was 30% in preterm labour cases and 6% in term labour cases (p=0.002). Basic vaginal pH, positive whiff test, and clue cells were significantly more frequent in the preterm group (p<0.05). Pathogenic organisms were isolated more often in preterm patients. Neonatal complications and postpartum outcomes showed no significant differences between BV-positive and BV-negative groups.
Conclusion: The incidence of BV is significantly higher among women in preterm labour. Routine antenatal screening and timely treatment may help reduce preterm births and associated complications.
