HIV infection among U.S. women has increased significantly over the last decade, especially in communities of color. CDC estimates that, in the United States, between 120,000 and 160,000 adult and adolescent females are living with HIV infection, including those with AIDS.
Between 1992 and 1998, the number of persons living with AIDS increased in all groups, as a result of the 1993 expanded AIDS case definition and, more recently, improved survival among those who have benefited from the new combination drug therapies. During that 6-year period, a growing proportion of women were living with AIDS, reflecting the ongoing shift in populations affected by the epidemic. In 1992, women accounted for 14% of persons living with AIDS -- by 1998, the proportion had grown to 20%.
In just over a decade, the proportion of all AIDS cases reported among adult and adolescent women more than tripled, from 7% in 1985 to 23% in 1999. The epidemic has increased most dramatically among women of color. African American and Hispanic women together represent less than one-fourth of all U.S. women, yet they account for more than three-fourths (77%) of AIDS cases reported to date among women in our country. In 1999 alone (see chart above), women of color represented an even higher proportion of cases.
While AIDS-related deaths among women were decreasing as of 1998, largely as a result of recent advances in HIV treatment, HIV/AIDS remains among the leading causes of death for U.S. women aged 25-44. And among African American women in this same age group, AIDS was the third leading case of death in 1998.
In 1999 most women (40%) reported with AIDS were infected through heterosexual exposure to HIV; injection drug use accounted for 27%. In addition to the direct risks associated with drug injection (sharing needles), drug use also is fueling the heterosexual spread of the epidemic. A large proportion of women infected heterosexually were infected through sex with an injection drug user. Reducing the toll of the epidemic among women will require efforts to combat substance abuse, in addition to reducing HIV risk behaviors.
Many HIV/AIDS cases among women in the United States are initially reported without risk information, suggesting that women may be unaware of their partners' risk factors or that health care providers are not documenting their risk. Historically, more than two-thirds of AIDS cases among women initially reported without identified risk were later reclassified as heterosexual transmission, and just over one-fourth were attributed to injection drug use.
