OBJECTIVE: Frequent vaginal douching has been associated with bacterial vaginosis. We investigated whether infrequent douching is also a risk factor for bacterial vaginosis.
METHODS: In this cross-sectional study, we recruited 411 African-American women of reproductive age who were visiting gynecologic or family planning clinics of 2 hospitals in New York City from 1999 to 2001. Detailed information on demographic characteristics, feminine hygiene practice, contraceptive use, and reproductive and medical history was collected through in-person interview. Pelvic examinations and laboratory tests on vaginal secretions were performed. Bacterial vaginosis was defined as Gram stain score of 7 or greater.
RESULTS: The overall prevalence of bacterial vaginosis in this population was 27%, similar to the national average. Water-vinegar solution was the most common douche. Although one half of the subjects reported douching regularly, only 2% douched frequently (once per week or more). Frequent douching in the past 3 months had a prevalence ratio of bacterial vaginosis of 2.35 (95% confidence interval 0.98-5.63). However, douching less than once per week was not associated with bacterial vaginosis.
CONCLUSION: Douching less than once per week, particularly with a water-vinegar douche, is not associated with bacterial vaginosis in this African-American population.
LEVEL OF EVIDENCE: III
