Background: Bacterial vaginosis (BV) is the most prevalent cause of abnormal vaginal discharge among pre-menopausal women and associated with adversities of sexual and reproductive health. The present study aimed to identify potential epidemiological and behavioural risk factors and clinical predictors of BV among women in Delhi, India. Methods: A cross-sectional study was conducted to assess 283 non-pregnant women aged 18-45 years for BV using Nugent's scoring criteria. Information on demographics, sexual behaviours, hygiene practices and clinical symptoms was obtained and evaluated for their association with Nugent-BV status. Results: A positive diagnosis for Nugent-BV was made in 69 (24.4%) participants, 55 (19.4%) were intermediate and 159 (65.2%) were negative for Nugent-BV. Infertility (p = .02) and recent unprotected sexual exposure (p = .02) were strongly associated with Nugent-BV. On the other hand, women who reported regular use of condoms during intercourse were more likely to test negative (p = .03). None of the patient complaints, however, had any significant correlation with Nugent-BV diagnosis. Conclusion: Women in their reproductive years share the highest burden of adversities associated with bacterial vaginosis. History of infertility, recent unprotected sexual exposure and frequent use of condoms were correlates having significant associations with Nugent-BV.
