ConclusionConclusion BV positive rate was 42% in
young women who douche. Predictors of BV in these
women were recent sex, multiple partners in recent 3-mo.

ImplicationsImplications Studies examining effects of
vaginal douching must account for confounding sexual behaviors.
Management of women with BV should include assessment for high risk sexual behavior and testing for STDs.
