| Background: Bacterial Vaginosis (BV) is a condition characterized by an imbalance in the normal vaginal flora, where Lactobacillus is replaced with mixed flora of aerobic, anaerobic and microaerophillic species. Bacterial vaginosis has been associated with adverse pregnancy outcomes. Likewise, aerobic vaginitis can cause perinatal complications.Aims: This study was conducted to determine the prevalence of vaginal dysbiosis (bacterial vaginosis and aerobic vaginitis) and its adverse pregnancy outcomes (maternal/fetal outcome) in pregnant women attending antenatal clinic in a tertiary care hospital in North India.Design: Prospective cohort studyMaterials and method: The prospective cohort study was conducted on women attending the antenatal clinic of a tertiary hospital. All obstetric and neonatal data covering antenatal events during the course of pregnancy, delivery, puerperium and condition of each newborn at the time of birth was collected. Vaginal dysbiosis was detected as per standard microbiological techniques.Conclusion: The findings help to understand the importance of targeted interventions, effective prenatal and perinatal care, and addressing socioeconomic and parity-related disparities to improve maternal and neonatal health outcomes. However further studies to explore the underlying causes of these distributions and develop strategies to optimize health care delivery and outcomes are required. |
