Factors associated with recurrent bacterial vaginosis.

OBJECTIVE

To determine whether menstrual abnormalities, multiple personal behaviors and some contraceptive methods, all of which have been described as potential causes of single episodes of bacterial vaginosis (BV), are associated with recurrent bacterial vaginosis (RBV).

STUDY

DESIGN

This was a retrospective, case-controlled study performed in an urban setting. Women with RBV and matched controls were mailed a survey that included multiple questions about potential risk factors for BV. Four-to-one matching of age groups was performed, with 28 RBV cases matched to 112 controls.

RESULTS

Among multiple possible predisposing factors, only African American ethnicity (p < 0.001) and > 1 male sex partner in the previous 2 years (p = 0.007) were strongly associated with RBV. Abnormal uterine bleeding, frequent intercourse without a condom or withdrawal, anal intercourse, menstrual hygiene product use, tub baths, back-to-front wiping after using the toilet, smoking, choice of contraceptive method (including condoms, the combination oral contraceptive, injectable medroxyprogesterone acetate or an intrauterine device) and douching were not associated with RBV.

CONCLUSION

Providers should counsel women with RBV to minimize their number of male sex partners. There are few data to support the recommendation of other behavioral changes.
