HIV risk behaviors and HIV seropositivity among young injection drug users.

Although injection drug use (IDU) is the major risk category for HIV infection in Puerto Rico and injection drug users start their drug injection careers very young, there is little information related to drug injection patterns of young IDUs. In this paper we report on factors found to be associated with HIV seropositivity among 255 young IDUs (16-24 years old). Overall, 23.5% subjects were HIV seropositive. Being 22 to 24 years old, having dropped out of school, having a history of incarceration, and having been diagnosed with STDs, and initiating drug use injection before 17 years of age were the factors significantly related to HIV seropositivity. Findings suggest that prevention programs should begin early in the development of youngsters. Special HIV and STD preventive programs for youngsters at risk of leaving school before completing high school should be a priority.
