Risk behaviors of persons with heterosexually acquired HIV infection in the United States: results of a multistate surveillance project.

To describe past risk behaviors among persons with heterosexually acquired human immunodeficiency virus (HIV) infection, we interviewed 497 persons > or = 18 years of age with heterosexually acquired HIV infection reported to 11 state and city health departments in the United States. Thirty-nine percent of persons reported using noninjection drugs in the past 5 years; noninjection drug use was highest among men whose sex partners injected drugs (53%). Sixteen percent of all persons used crack, and 17% were classified as potential alcoholics; among men, 29% were classified as potential alcoholics. Of the 49% of men who reported paying a woman for sex, 86% did so multiple times. Most persons had multiple sex partners in the past 5 years; however, 35% of the women had only one sex partner. Thirty-four percent of the women and 50% of the men had been treated for a sexually transmitted disease in the past 10 years. Seventy-four percent of the women and 68% of the men had never used condoms in the 5 years before they knew they were HIV positive. Among these people with heterosexually acquired HIV, noninjection drug use was common, many men have paid someone for sex, and many women have not had multiple sex partners. These findings have important implications for the types of prevention programs that can most successfully lessen the spread of HIV among heterosexuals.
