Objective: To determine whether bacterial vaginosis (BV) is associated with sexual activity between women.
Study Design: Cross-sectional survey of 708 new patients attending 2 sexual health clinics for lesbians and bisexual women in London, U.K. Questionnaire for demographic, sexual history, and sexual practice data linked with the results of genitourinary examination.
Results: BV was common (31.4%). The odds of BV was significantly associated with larger numbers of female sexual partners (odds ratio [OR], 1.6; confidence interval [CI], 1.05–2.44 for ≥11 compared with 1–5 partners) and with smoking (OR, 1.43; CI, 1.01–2.03), but not with sex with men or vaginal douching.
Conclusions: BV is common in women who have sex with women (WSW). The increasing odds of BV with larger numbers of female sexual partners suggest that BV may be sexually transmitted between women.
A study of lesbians and bisexual women in London showed that bacterial vaginosis was common, and associated with numbers of female sexual partners. Findings suggest that bacterial vaginosis can be sexually transmitted between women.
