Over 8,000 adolescents and young adults (4,111 males; 4,085 females) report
ed on several HIV-related risk behaviors during enrollment into 10 service
demonstration projects targeted to youth living with, or at risk for, HIV.
Distinct risk patterns emerged by gender when predicting HIV serostatus (ve
rsus unknown serostatus/negative serostatus). Males who had injection drug
risk histories, had sex with an HIV positive partner, had sexually transmit
ted diseases, had sex with males, and/or were homeless had an inflated risk
of being HIV positive. Females who engaged in sex with an HN partner, had
sex with an injection drug user, and/or had sexually transmitted diseases,
were at the highest HIV risk. For both samples, engaging in sex with women
reduced the likelihood of HIV positive status. Very basic information about
risk factors obtained at service intake offers important information about
HIV status of "high risk" youth presenting for care in community programs,
as well as suggests clear risk factors for targeted preventive efforts.
