Unique Identifier : AIDSLINE ICA10/94370092 AB OBJECTIVE: To assess differences in HIV-risk behavior between bisexual and heterosexual women attending public sexually transmitted disease (STD) clinics in Los Angeles County. METHODS: We analyzed data from women at eight STD clinics who consented to HIV antibody testing and completed a standardized interview between June 1990 and December 1992. Drug use and sexual behavior were compared for women reporting exclusively heterosexual activity and those reporting bisexual activity since 1978. Odds ratios (OR) and 95% confidence intervals were calculated after adjusting for racial/ethnic, age, and educational differences between the two groups. RESULTS: Bisexual activity was reported by 271 (3.4%) of the 7,868 women who participated. Four (1.5%) bisexual women and 61 (0.8%) heterosexual women were HIV seropositive (OR 1.7 [0.5, 5.4]). Bisexual women were more likely than heterosexual women to report injection drug use (24.1% vs. 4.0%; OR 8.2 [5.8, 11.6]), cocaine use during the preceding 6 months (39.1% vs. 12.8%; OR 3.6 [2.7, 4.8]), sex with a bisexual man (35.6% vs. 4.3%; OR 9.5 [6.8, 13.2]), sex with a man who injects drugs (37.4% vs. 10.3%; OR 4.5 [3.3, 6.2]), anal intercourse (42.0% vs. 14.8%; OR 3.2 [2.4, 4.3]), and trading sex for money or drugs (43.4% vs. 10.9%; OR 5.7 [4.3, 7.6]). Among women reporting sex with 1 or more men during the preceding 12 months, 54.4% of heterosexual women and 31.8% of bisexual women reported no condom use (OR 2.4 [1.7, 3.2]). DISCUSSION AND CONCLUSIONS: While HIV seroprevalence in this STD clinic population was relatively low, bisexual women were much more likely than heterosexual women to engage in behaviors that increase their risk of HIV infection. Specific efforts should be made to intensify STD and drug prevention and treatment services for bisexual women.
