Risks for acquisition of bacterial vaginosis among women who report sex with women: a cohort study

Bacterial vaginosis (BV) is common in women who have sex with women. While cross-sectional data support a role for sexual transmission, risks for incident BV have not been prospectively studied in this group. We studied risks for BV acquisition in a prospective cohort study of women (age 16-35 years...

Description
Summary:Bacterial vaginosis (BV) is common in women who have sex with women. While cross-sectional data support a role for sexual transmission, risks for incident BV have not been prospectively studied in this group. We studied risks for BV acquisition in a prospective cohort study of women (age 16-35 years) who reported sex with other women (>or=1 partner, prior year). Women were followed for one year with examinations at quarterly visits and for genital symptoms at any time. Species-specific 16S rRNA gene PCRs for BV-associated bacteria (BVAB) were applied to vaginal fluid obtained at enrollment. Sexual behaviors were ascertained by computer-assisted interview. Of 335 participants, 239 had no BV at baseline; 199 were seen in follow-up (median follow-up 355 days, 4.0 visits/subject). Forty women experienced >or=1 BV episode. Risks for incident BV were presentation
