PRIMARY: To identify factors associated with risk of HIV infection through heterosexual activity among urban, inner-city women.

SECONDARY: To identify correlates of high-risk behaviors in order to provide a basis for future intervention studies.

At baseline and at 6-month intervals, participants are interviewed about their sexual behavior, drug and alcohol-related behaviors, and recent medical history, and are given a psychosocial assessment. They also undergo a physical exam, including pelvic exam and colposcopy, and have blood and urine specimens collected for HIV testing, drug screening, and STD evaluation. Additionally, participants are given pre- and post-test counseling and education, including information about social services. They are provided with basic gynecological care and either treatment or referral for medical problems.

Participants must meet the following criteria:

• HIV-negative, sexually active women living in social and sexual proximity to men at high risk for acquiring HIV infection.
• Able to speak English, Spanish, or Creole.
• Living in the geographic area surrounding Kings County Hospital in Brooklyn, New York. (Hospital-based and community-based recruitment sites will be utilized.)

Personal history of parenteral drug use by self-report or urine test. Heterosexual contact with men at high risk for HIV infection.
