Injection drug use among street-involved youth in a Canadian setting

BMC Public Health. 2009 Jun 3;9:171. doi: 10.1186/1471-2458-9-171.

Abstract

Background: Street-involved youth contend with an array of health and social challenges, including elevated rates of blood-borne infections and mortality. In addition, there has been growing concern regarding high-risk drug use among street-involved youth, in particular injection drug use. We undertook this study to examine the prevalence of injection drug use and associated risks among street-involved youth in Vancouver, Canada.

Methods: From September 2005 to November 2007, baseline data were collected for the At-Risk Youth Study (ARYS), a prospective cohort of street-recruited youth aged 14 to 26 in Vancouver, Canada. Using multiple logistic regression, we compared youth with and without a history of injection.

Results: The sample included 560 youth among whom the median age was 21.9 years, 179 (32%) were female, and 230 (41.1%) reported prior injection drug use. Factors associated with injection drug use in multivariate analyses included age >or= 22 years (adjusted odds ratio [AOR] = 1.18, 95% CI: 1.10-1.28); sex work involvement (AOR = 2.17, 95% CI: 1.35-3.50); non-fatal overdose (AOR = 2.10, 95% CI: 1.38-3.20); and hepatitis C (HCV) infection (AOR = 22.61, 95% CI: 7.78-65.70).

Conclusion: These findings highlight an alarmingly high prevalence of injection drug use among street-involved youth and demonstrate its association with an array of risks and harms, including sex work involvement, overdose, and HCV infection. These findings point to the need for a broad set of policies and interventions to prevent the initiation of injection drug use and address the risks faced by street-involved youth who are actively injecting.
