    <p>Abstract</p> <p>Background</p> <p>Epidemiology of HCV infection among drug users (DUs) has been widely studied. Prevalence and sociobehavioural data among DUs are therefore available in most countries but no study has taken into account in the sampling weights one important aspect of the way of life of DUs, namely that they can use one or more specialized services during the study period. In 2004–2005, we conducted a national seroepidemiologic survey of DUs, based on a random sampling design using the Generalised Weight Share Method (GWSM) and on blood testing.</p> <p>Methods</p> <p>A cross-sectional multicenter survey was done among DUs having injected or snorted drugs at least once in their life. We conducted a two stage random survey of DUs selected to represent the diversity of drug use. The fact that DUs can use more than one structure during the study period has an impact on their inclusion probabilities. To calculate a correct sampling weight, we used the GWSM. A sociobehavioral questionnaire was administered by interviewers. Selected DUs were asked to self-collect a fingerprick blood sample on blotting paper.</p> <p>Results</p> <p>Of all DUs selected, 1462 (75%) accepted to participate. HCV seroprevalence was 59.8% [95% CI: 50.7–68.3]. Of DUs under 30 years, 28% were HCV seropositive. Of HCV-infected DUs, 27% were unaware of their status. In the month prior to interview, 13% of DUs shared a syringe, 38% other injection parapharnelia and 81% shared a crack pipe. In multivariate analysis, factors independently associated with HCV seropositivity were age over 30, HIV seropositivity, having ever injected drugs, opiate substitution treatment (OST), crack use, and precarious housing.</p> <p>Conclusion</p> <p>This is the first time that blood testing combined to GWSM is applied to a DUs population, which improve the estimate of HCV prevalence. HCV seroprevalence is high, indeed by the youngest DUs. And a large proportion of DUs are not aware of their status. Our multivariate analysis identifies risk factors such as crack consumption and unstable housing.</p

    ObjectivesIndigenous leaders and child and family advocates are deeply concerned about the health impacts of the child welfare system, including HIV vulnerability. The objectives of this study were to describe the prevalence of having been apprehended into the child welfare system and associated HIV vulnerabilities among young Indigenous people who use drugs.MethodsThe Cedar Project is a cohort of young Indigenous people ages 14-30 years who use illicit drugs in Vancouver and Prince George, British Columbia. Multivariable logistic regression modeling determined associations between a history of involvement in the child welfare system and vulnerability to HIV infection.ResultsOf 605 participants, 65% had been taken from their biological parents. Median age of first apprehension was 4 years old. Having been sexually abused, having a parent who attended residential school and being HIV-positive were all independently associated with having been involved in the child welfare system. Participants who had been involved in the child welfare system were also more likely to have been homeless, paid for sex, diagnosed and hospitalized with mental illness, self-harmed, thought about suicide, and attempted suicide. Among participants who used injection drugs, those who had been involved in child welfare were more likely to have shared needles and overdosed.ConclusionThis study has found compelling evidence that young Indigenous people who use drugs in two cities in BC are experiencing several distressing health outcomes associated with child welfare involvement, including HIV infection. Jurisdictional reforms and trauma-informed programs that use culture as intervention are urgently needed
