Partner History Raises Gay Women's Vaginosis Risk

Article excerpt

CHICAGO -- The biggest risk factor for bacterial vaginosis among gay or bisexual women is having a sex partner with a history of the disorder--an association that increases the chances of bacterial vaginosis by more than 400%, Dr. Jeanne Marrazzo said at a meeting on the prevention of sexually transmitted diseases.

Sharing sexual toys almost doubled the risk of developing bacterial vaginosis (BV) among these women, said Dr. Marrazzo of the University of Washington, Seattle.

Although this association was not statistically significant, when it is combined with the risk of a partner's positive history, it suggests that the exchange of vaginal fluids plays a key role in the development of BV for this population, she said.

Dr. Marrazzo presented the preliminary results of a 1-year longitudinal study examining the rates of bacterial vaginosis in 335 women, including 47 couples (94 women). The women's median age was 25 years; 88% were white. Most (305) reported sexual activity within the last 3 months; of these, 276 reported having had at least one female partner, and 18% reported both male and female partners. For those reporting sex with a male within the last 3 months, only 25% reported having used a condom.

A third of the women had a history of bacterial vaginosis--a somewhat high prevalence, especially in light of the group's very low rate of douching (6%), a behavior that is strongly associated with the disorder, Dr. Marrazzo said.

All of the women completed a detailed computer survey of their sexual habits. Their symptoms were assessed clinically by Amsel criteria; bacterial vaginosis was confirmed with Gram stain of vaginal fluid and Nugent criteria. The overall prevalence of BV was 29%, which is higher than that usually seen at clinics in the United States, Dr. Marrazzo said. Of these women, 40% were symptomatic at the time of clinical assessment.

In terms of sexual practice, all of the sexually active women had experienced receptive vaginal or oral sex, including penetration with fingers, a penis, or toys; 40% had experienced receptive anal sex with fingers, penis or toys; and 22% reported sharing a vaginal toy with a female partner. …
