WOMEN AT A SEXUALLY-TRANSMITTED DISEASE CLINIC WHO REPORTED SAME-SEX CONTACT - THEIR HIV SEROPREVALENCE AND RISK BEHAVIORS

Objectives. This study compares characteristics, behaviors, and human immunodeficiency virus (HIV) infection in women who reported same-sex contact and women who had sex only with men. Methods. Participants wer e patients attending a New York City sexually transmitted disease clin ic. Structured questionnaires were administered by interviewers. Resul ts. Overall, 9% (135/1518) of women reported same-sex contact; among t hese, 93% also reported contact with men. Women reporting same-sex con tact were more likely than exclusively heterosexual women to be HIV se ropositive (17% vs 11%; odds ratio [OR] = 1.7, 95% confidence interval [CI] = 1.0, 2.6), to exchange sex for money/drugs (48% vs 12%, OR = 6 .7,: 95% CI = 4.6, 9.8), to inject drugs (31% vs 7%, OR = 6.3, 95% CI = 4.1, 9.5), and to use crack cocaine (31% vs 15%, OR = 3.3, 95% CI = 2.2, 4.8). HIV in women reporting same-sex contact was associated with history of syphilis (OR = 8.8), sex for crack (OR = 5.7), and injecti on drug use (OR = 4.5). Conclusions. In this study, women who reported same-sex contact were predominantly bisexual. They had more HIV risk behaviors and were more often HIV seropositive than women who had sex only with men. Among these bisexual women, heterosexual contact and in jection drug use were the most likely sources of HIV. There was no evi dence of female-to-female transmission.
