The Cedar Project: Racism and its impacts on health and wellbeing among young Indigenous people who use drugs in Prince George and Vancouver, BC.

Racism continues to drive health disparities between Indigenous and non-Indigenous peoples in Canada. This study focuses on racism experienced by young Indigenous people who have used drugs in British Columbia (BC), and predictors of interpersonal racism. Cedar Project is a community-governed cohort study involving young Indigenous people who use drugs in Vancouver and Prince George, BC. This cross-sectional study included data collected between August 2015-October 2016. The Measure of Indigenous Racism Experiences (MIRE) scale was used to assess experiences of interpersonal racism across 9 unique settings on a 5-point Likert scale, collapsing responses into three categories (none/low/high). Multinomial logistic regression models were used to examine associations between key variables and interpersonal racism. Among 321 participants, 79% (n = 255) experienced racism in at least one setting. Thirty two percent (n = 102) experienced high interpersonal racism from police, governmental agencies (child 'welfare', health personnel), and in public settings. Ever having a child apprehended (AOR:2.76, 95%CI:1.14-6.65), probable post-traumatic stress (AOR:2.64; 95%CI:1.08-6.46), trying to quit substances (AOR:3.69; 95%CI:1.04-13.06), leaving emergency room without receiving treatment (AOR:3.05; 95%CI:1.22-7.64), and having a traditional language spoken at home while growing up (AOR:2.86; 95%CI:1.90-6.90) were associated with high interpersonal racism. Among women, experiencing high interpersonal racism was more likely if they lived in Prince George (AOR:3.94; 95%CI:1.07-14.50), ever had a child apprehended (AOR:5.09; 95%CI:1.50-17.30), and had probable post-traumatic stress (AOR:5.21; 95%CI:1.43-18.95). Addressing racism experienced by Indigenous peoples requires immediate structural systemic, and interpersonal anti-racist reforms.

Overcoming the soul wound: Reflecting on experiences and resilience of intergenerational residential school survivors.

BACKGROUND: Between 1883 and 1996, thousands of Indigenous children were apprehended into Canada's Residential School System. Survivors and their descendants have testified to genocidal harms caused across generations. Yet, Indigenous Peoples continue to exist and resist through inherent resilience described by intergenerational survivors in this paper. OBJECTIVE: This article focuses on stories demonstrating the strength, power, and resilience of intergenerational residential school survivors. PARTICIPANTS & SETTING: Cedar Project is an Indigenous-led cohort study that began as a HIV/AIDS response and contributes to healing among young Indigenous people who use drugs in British Columbia, Canada. It is governed by the Cedar Project Partnership, an Indigenous body of Elders, leaders, and health/social services experts. METHODS: We present qualitative research involving in-depth interviews carried out with Cedar participants who have experienced significant and complex adversities including childhood maltreatment and illicit drug use. Woven throughout, Indigenous scholars who are themselves intergenerational (children and grandchildren) of residential school survivors provide first-person reflections on the findings. RESULTS: Analysis focused on narratives of resilience and resistance to stresses of intergenerational traumas across three broad themes: working to break cycles of intergenerational trauma; foundations of resilience and making positive changes and; hopes and dreams. CONCLUSIONS: Findings establish deeper understanding of processes that enable young people to cope with stresses of intergenerational traumas while facing institutional and structural barriers to wellness. Reflections provide context about how intergenerational experiences intersect with challenges that young intergenerational survivors continue to face. We highlight pathways to healing and sources of strength that inform recommendations for wellness.

Women in the 2019 hepatitis C cascade of care: findings from the British Columbia Hepatitis Testers cohort study.

BACKGROUND: Women living with hepatitis C virus (HCV) are rarely addressed in research and may be overrepresented within key populations requiring additional support to access HCV care and treatment. We constructed the HCV care cascade among people diagnosed with HCV in British Columbia, Canada, as of 2019 to compare progress in care and treatment and to assess sex/gender gaps in HCV treatment access. METHODS: The BC Hepatitis Testers Cohort includes 1.7 million people who tested for HCV, HIV, reported cases of hepatitis B, and active tuberculosis in BC from 2000 to 2019. Test results were linked to medical visits, hospitalizations, cancers, prescription drugs, and mortality data. Six HCV care cascade stages were identified: (1) antibody diagnosed; (2) RNA tested; (3) RNA positive; (4) genotyped; (5) initiated treatment; and (6) achieved sustained virologic response (SVR). HCV care cascade results were assessed for women, and an 'inverse' cascade was created to assess gaps, including not being RNA tested, genotyped, or treatment initiated, stratified by sex. RESULTS: In 2019, 52,638 people with known sex were anti-HCV positive in BC; 37% (19,522) were women. Confirmatory RNA tests were received by 86% (16,797/19,522) of anti-HCV positive women and 83% (27,353/33,116) of men. Among people who had been genotyped, 68% (6756/10,008) of women and 67% (12,640/18,828) of men initiated treatment, with 94% (5023/5364) of women and 92% (9147/9897) of men achieving SVR. Among the 3252 women and 6188 men not yet treated, higher proportions of women compared to men were born after 1975 (30% vs. 21%), had a mental health diagnosis (42% vs. 34%) and had used injection drugs (50% vs. 45%). Among 1619 women and 2780 men who had used injection drugs and were not yet treated, higher proportions of women than men used stimulants (64% vs. 57%), and opiates (67% vs. 60%). CONCLUSIONS: Women and men appear to be equally engaged into the HCV care cascade; however, women with concurrent social and health conditions are being left behind. Treatment access may be improved with approaches that meet the needs of younger women, those with mental health diagnoses, and women who use drugs.

The Cedar Project: exploring the role of colonial harms and childhood maltreatment on HIV and hepatitis C infection in a cohort study involving young Indigenous people who use drugs in two Canadian cities.

OBJECTIVES: This study examined associations between childhood maltreatment, colonial harms and sex/drug-related risks for HIV and hepatitis C virus (HCV) infection among young Indigenous people who use drugs. DESIGN: The Cedar Project is a cohort involving young Indigenous people who use drugs in British Columbia (BC), Canada. Indigenous collaborators, collectively known as the Cedar Project Partnership, govern the entire research process. SETTING: Vancouver is a large city on the traditional territory of the Coast Salish peoples. Prince George is a mid-sized city, on the traditional territory of Lheidli T'enneh First Nation. PARTICIPANTS: 420 participants completed the Childhood Trauma Questionnaire and returned for follow-up from 2003 to 2016. PRIMARY/SECONDARY OUTCOME MEASURES: Primary outcomes were HIV and HCV infection over the study period. Secondary outcomes included sex and substance use-related risks. RESULTS: Prevalence of childhood maltreatment was 92.6% experienced any maltreatment; 73.4% experienced emotional abuse; 62.6% experienced physical abuse; 60.3% experienced sexual abuse; 69.5% experienced emotional neglect and 79.1% experienced physical neglect. We observed significant associations between childhood maltreatment and apprehensions into residential schools and foster care. All maltreatment types were associated with higher odds of sex/substance use-related risks; sexual abuse was associated with higher odds of HCV infection (adjusted OR: 1.67; 95% CI 1.05 to 2.66; p=0.031). CONCLUSIONS: Findings reflect high prevalence of childhood maltreatment and their associations with HIV/HCV risk and HCV infection. Public health prevention and treatment initiatives must be trauma informed and culturally safe to support healing, health, and well-being.

The "Sticky Notes" Method: Adapting Interpretive Description Methodology for Team-Based Qualitative Analysis in Community-Based Participatory Research.

Community-based participatory research (CBPR) has a long history within HIV research, yet little work has focused on facilitating team-based data analysis within CBPR. Our team adapted Thorne's interpretive description (ID) for CBPR analysis, using a color-coded "sticky notes" system to conduct data fragmentation and synthesis. Sticky notes were used to record, visualize, and communicate emerging insights over the course of 11 in-person participatory sessions. Data fragmentation strategies were employed in an iterative four-step process that was reached by consensus. During synthesis, the team created and recreated mind maps of the 969 sticky notes, from which we developed categories and themes through discussion. Flexibility, trust, and discussion were key components that facilitated the evolution of the final process. An interactive, team-based approach was central to data co-creation and capacity building, whereas the "sticky notes" system provided a framework for identifying and sorting data.

The Cedar Project: Historical, structural and interpersonal determinants of involvement in survival sex work over time among Indigenous women who have used drugs in two Canadian cities.

BACKGROUND: Indigenous women involved in survival sex work face multiple layers of discrimination, criminalization and alarming levels of intergenerational and lifetime trauma. This longitudinal study examined historical, structural and interpersonal factors associated with survival sex work involvement among Indigenous women who have used drugs in British Columbia (BC), Canada. METHODS: The Cedar Project is an ongoing cohort study involving young Indigenous people who have used illicit drugs in Vancouver and Prince George, BC. Data was collected every 6 months from 2007 to 2016 . Generalized linear mixed-effects modeling was used to model survival sex work involvement, defined as exchanging sex for money, drugs, food or shelter in the previous six months. RESULTS: Among 292 participants, 34% reported their family always/often lived by traditional culture and 37% reported their family always/often spoke their traditional language. In contrast, 48% had a parent in residential school and 72% were removed from their biological parents. In total, 55% of women were involved in survival sex work at baseline. In adjusted analyses, those who were single (ARR: 1.91; 95% CI: 1.50-2.35), identified as two-spirit (ARR: 2.16; 95% CI: 1.36-2.91), experienced sexual assault (ARR: 1.90; 95% CI: 1.22-2.58), were denied access to shelter (ARR: 1.71; 95% CI: 1.18-2.28), used crack daily (ARR: 2.85; 95% CI: 2.36-3.31), used injection drugs (ARR: 2.52; 95% CI: 1.98-3.07), and were unable to access substance use treatment (ARR: 1.58; 95% CI: 1.15-2.05) were more likely to be involved in sex work. CONCLUSION: Indigenous-governed, wellness-based harm-reduction interventions, and structural reforms addressing housing insecurity and normalization of a culture of violence against Indigenous women, especially those involved in survival sex work, are urgently needed in Canada.

Prenatal hepatitis C screening, diagnoses, and follow-up testing in British Columbia, 2008-2019.

OBJECTIVE: Current guidelines in British Columbia recommend prenatal screening for hepatitis C antibodies (anti-HCV) if risk factors are present. We aimed to estimate frequency of prenatal anti-HCV testing, new diagnoses, repeated and follow-up testing among BC women. METHODS: BC Centre for Disease Control Public Health Laboratory data estimated the number of BC women (assigned female at birth or unknown sex) aged 13-49 who received routine prenatal serological screening (HIV, hepatitis B, syphilis and rubella) from 2008-2019. Anti-HCV tests ordered the same day as routine prenatal screens were considered prenatal anti-HCV tests. Assessment of follow-up was based on HCV RNA and/or genotype testing within one year of new prenatal anti-HCV diagnoses. RESULTS: In 2019, 55,202 routine prenatal screens were carried out for 50,392 BC women. Prenatal anti-HCV tests increased significantly, from 19.6% (9,704/49,515) in 2008 to 54.6% (27,516/50,392) in 2019 (p<0.001). New prenatal anti-HCV diagnoses (HCV positive diagnoses at first test or seroconversions) declined from 14.3% in 2008 to 10.1% in 2019. The proportion of women with new prenatal anti-HCV diagnoses that were a result of a first HCV test declined from 0.3% (29/9,701) in 2008 to 0.03% (8/27,500) in 2019. For women known to be anti-HCV positive at the time of prenatal screening, the proportion who had a prenatal anti-HCV test increased from 35.6% in 2008 to 50.8% in 2019. CONCLUSION: Prenatal anti-HCV testing increased substantially over the study period. However, new HCV diagnoses remained relatively stable, suggesting that a considerable proportion of BC women with low or no risk are being screened as part of prenatal care. The vast majority of women with new HCV diagnoses receive appropriate follow-up HCV RNA and genotype testing, which may indicate interest in HCV treatment. These findings contribute to the discussion around potential for prenatal anti-HCV screening in an effort to eliminate HCV.

The Cedar Project - Mobile Phone Use and Acceptability of Mobile Health Among Young Indigenous People Who Have Used Drugs in British Columbia, Canada: Mixed Methods Exploratory Study.

BACKGROUND: Indigenous leaders continue to be concerned about high rates of HIV and barriers to HIV treatment among young Indigenous people involved in substance use. Growing evidence suggests that using mobile phones for health (mHealth) may be a powerful way to support connection with health services, including HIV prevention and treatment. OBJECTIVE: This study examined the patterns of mobile phone ownership and use among young Indigenous people who have used drugs living with or vulnerable to HIV and explored the acceptability of mHealth to support access to health care in this population. METHODS: The Cedar Project is a cohort study involving young Indigenous people who have used drugs in Vancouver and Prince George, British Columbia. This mixed methods exploratory study involved 131 Cedar Project participants enrolled in our WelTel mHealth program. At enrollment, participants completed a questionnaire related to mobile phone use and interest in mHealth. Data were linked to Cedar Project questionnaires and serodata. We present comparative statistics (quantitative) and results of a rapid thematic analysis (qualitative) related to mobile phone patterns and interest in receiving mHealth. RESULTS: Less than half of the participants (59/130; 45.4%) reported owning a phone. Among those with a phone, the majority owned a smartphone (46/59; 78%). Most participants with a phone reported having an unlimited texting plan (39/55; 71%), using the internet on their phone (44/59; 75%), and texting daily (44/55; 80%). A majority reported that using a mobile phone for health would be invaluable (120/130; 92.3%). There were no differences in mHealth acceptance between participants who owned a phone and those who did not (P>.99). All but one participant living with HIV felt using a mobile phone would be helpful for their health, while a small proportion of HIV-negative participants remained unsure (1.9% vs 11.7%; P=.047). In response to open-ended questions asking why using a mobile phone may be helpful for health, participants identified a diverse set of anticipated benefits: (1) connection for emotional, mental, and spiritual support, (2) connection to family, (3) staying in touch and/or being reachable, (4) overcoming current barriers to phone use, (5) convenience, privacy, and safety, and (6) access to health care and emergency services. CONCLUSIONS: We observed high acceptance and interest in using mobile phone technology for health despite low rates of personal mobile phone connectivity among young Indigenous people who have used drugs living with and vulnerable to HIV in British Columbia, Canada. Mobile phones were viewed as a way to support connections and relationships that are seen as critical to health and well-being among young Indigenous people in this study. Findings may be useful for health care providers preparing to scale up mHealth programs to support HIV prevention and treatment in this population.

Real-world Effectiveness of Sofosbuvir/Velpatasvir for Treatment of Chronic Hepatitis C in British Columbia, Canada: A Population-Based Cohort Study.

BACKGROUND: Clinical trials show high efficacy of sofosbuvir/velpatasvir (SOF/VEL), but there are limited data from "real-world" settings. We aimed to evaluate SOF/VEL effectiveness for all hepatitis C virus (HCV) genotypes (GTs) in British Columbia (BC), Canada. METHODS: We used the BC Hepatitis Testers Cohort, which includes all HCV cases in the province (1990-2015) linked to administrative databases, including prescriptions to end of 2018. We measured sustained virologic response (SVR; negative RNA ≥10 weeks after treatment end) and identified characteristics associated with non-SVR. Conservatively, we excluded individuals with no assessment for SVR if their last RNA test after treatment initiation was negative (but included if positive). RESULTS: Of 2821 eligible participants, most were infected with GT1 (1076, 38.1%) or GT3 (1072, 38.0%), and a minority (278, 9.9%) were treated with RBV. SVR was 94.6% (2670/2821) overall and 94.5% (1017/1076) for GT1, 96.4% (512/531) for GT2, and 93.7% (1004/1072) for GT3. When disaggregated by GT, treatment regimen, and cirrhosis/treatment experience, SVR was lowest (30/40, 75.0%) among treatment-experienced GT3 individuals treated with RBV. Characteristics associated with non-SVR in multivariable analysis included younger age, RBV addition, and being a person with HIV (PWH) or who injects/injected drugs (PWID). When treatment regimen (±RBV) was removed from multivariable model, treatment experience was associated with non-SVR for GT3. Of 151 non-SVR individuals, 56.3% were nonvirological failures (treatment incomplete/no assessment for SVR) and 43.7% were virological failures (nonresponse/relapse). A disproportionately high percentage of non-SVR among PWID was due to nonvirological failure. CONCLUSIONS: SOF/VEL was highly effective in this "real-world" population-based cohort. Additional support is required for PWID/PWH to reach SVR.

Loss to follow-up: A significant barrier in the treatment cascade with direct-acting therapies.

Effectiveness of direct-acting antiviral (DAA) therapies could be influenced by patient characteristics such as comorbid conditions, which could lead to premature treatment discontinuation and/or irregular medical follow-ups. Here, we evaluate loss to follow-up and treatment effectiveness of sofosbuvir/ledipasvir ± ribavirin (SOF/LDV ± RBV), ombitasvir/paritaprevir/ritonavir + dasabuvir ± ribavirin (OBV/PTV/r + DSV ± RBV) for hepatitis C virus (HCV) genotype 1 (GT1) and sofosbuvir + ribavirin (SOF + RBV) for genotype 3 (GT3) in British Columbia Canada: The British Columbia Hepatitis Testers Cohort includes data on individuals tested for HCV since 1992, integrated with medical visit, hospitalization and prescription drug data. HCV-positive individuals who initiated DAA regimens, irrespective of treatment completion, for GT1 and GT3 until 31 December, 2017 were included. Factors associated with sustained virological response (SVR) and loss to follow-up were assessed by using multivariable logistic regression models. In total 4477 individuals initiated DAAs. The most common prescribed DAA was SOF/LDV ± RBV with SVR of 95%. The highest SVR of 99.5% was observed among OBV/PTV/r + DSV-treated patients. Overall, 453 (10.1%) individuals were lost to follow-up. Higher loss to follow-up was observed among GT1 patients treated with OBV (17.8%) and GT3 patients (15.7%). The loss to follow-up rate was significantly higher among individuals aged <60 years, those with a history of injection drug use (IDU), on opioid substitution therapy and with cirrhosis. Our findings indicate that loss to follow-up exceeds viral failure in HCV DAA therapy and its rate varies significantly by genotype and treatment regimen. Depending on the aetiology of lost to follow-up, personalized case management for those with medical complications and supporting services among IDU are needed to achieve the full benefits of effective treatments.

Experiences of the HIV Cascade of Care Among Indigenous Peoples: A Systematic Review.

Indigenous leaders remain concerned that systemic oppression and culturally unsafe care impede Indigenous peoples living with HIV from accessing health services that make up the HIV cascade of care. We conducted a systematic review to assess the evidence related to experiences of the HIV care cascade among Indigenous peoples in Australia, Canada, New Zealand, and United States. We identified 93 qualitative and quantitative articles published between 1996 and 2017 reporting primary data on cascade outcomes disaggregated by Indigenous identity. Twelve involved data from Australia, 52 from Canada, 3 from New Zealand and 26 from United States. The majority dealt with HIV testing/diagnosis (50). Relatively few addressed post-diagnosis experiences: linkage (14); retention (20); treatment initiation (21); adherence (23); and viral suppression (24). With the HIV cascade of care increasingly the focus of global, national, and local HIV agendas, it is critical that culturally-safe care for Indigenous peoples is available at all stages.

Cango Lyec (Healing the Elephant): Gender Differences in HIV Infection in Post-conflict Northern Uganda.

BACKGROUND: As previously encamped resettle, potential for rapid HIV transmission in post-conflict Northern Uganda is concerning. Women in particular may be experiencing heightened vulnerability resulting from war-related sexual violence. SETTING: Cango Lyec (Healing the Elephant) Project is a cohort involving conflict-affected people in 3 districts in Northern Uganda. METHODS: Eight randomly selected communities were mapped, and a census was conducted. Participants aged 13-49 years completed questionnaires in Luo on war-related experiences, mental health, sexual vulnerabilities, and sociodemographics. Blood samples were tested for HIV and syphilis. Baseline data from all sexually active participants was used to determine gender differences in HIV prevalence. Multivariate modeling determined correlates of HIV by gender. RESULTS: Among 2008 participants, HIV prevalence was higher among women [17.2; 95% confidence interval (CI): 14.7 to 19.7] compared to men (10.6; 95% CI: 8.0 to 13.2, <0.001). Among women, correlates of HIV included: war-related sexual assault [adjusted odds ratio (AOR): 1.95; 95% CI: 1.16 to 3.26]; probable depression (AOR: 2.22; 95% CI: 1.46 to 3.37); probable post-traumatic stress disorder (AOR: 2.03; 95% CI: 1.45 to 2.84); experiencing ≥12 traumatic events (AOR: 2.04; 95% CI: 1.31 to 3.18); suicide ideation (AOR: 1.67; 95% CI: 1.22 to 2.28); living in a female-headed household (AOR: 2.76; 95% CI: 1.70 to 4.49); first sexual partner ≥10 years older (AOR: 1.69; 95% CI: 1.07 to 2.67); sex for exchange (AOR: 5.51; 95% CI: 1.76 to 17.31); having 2 (AOR: 2.54; 95% CI: 1.23 to 5.23) or 3+ (AOR: 4.65; 95% CI: 2.65 to 8.18) sexual partners; inconsistent condom use (AOR: 0.40; 95% CI: 0.29 to 0.57); genital ulcers (AOR: 3.08; 95% CI: 2.16 to 4.38); active syphilis (AOR: 4.33; 95% CI: 1.22 to 15.40); and ill health without medical care (AOR: 2.02; 95% CI: 1.22 to 3.34). Among men, correlates of HIV included no condom at sexual debut (AOR: 1.92; 95% CI: 1.30 to 2.83) and genital ulcers (AOR: 4.40; 95% CI: 1.35 to 14.40). CONCLUSION: Women are disproportionately impacted by HIV, trauma, and depression in this conflict-affected population. Trauma-informed HIV prevention and culturally safe mental health initiatives are urgently required.

The Cedar Project: mortality among young Indigenous people who use drugs in British Columbia.

BACKGROUND: Young Indigenous people, particularly those involved in the child welfare system, those entrenched in substance use and those living with HIV or hepatitis C, are dying prematurely. We report mortality rates among young Indigenous people who use drugs in British Columbia and explore predictors of mortality over time. METHODS: We analyzed data collected every 6 months between 2003 and 2014 by the Cedar Project, a prospective cohort study involving young Indigenous people who use illicit drugs in Vancouver and Prince George, BC. We calculated age-standardized mortality ratios using Indigenous and Canadian reference populations. We identified predictors of mortality using time-dependent Cox proportional hazard regression. RESULTS: Among 610 participants, 40 died between 2003 and 2014, yielding a mortality rate of 670 per 100 000 person-years. Young Indigenous people who used drugs were 12.9 (95% confidence interval [CI] 9.2-17.5) times more likely to die than all Canadians the same age and were 7.8 (95% CI 5.6-10.6) times more likely to die than Indigenous people with Status in BC. Young women and those using drugs by injection were most affected. The leading causes of death were overdose (n = 15 [38%]), illness (n = 11 [28%]) and suicide (n = 5 [12%]). Predictors of mortality included having hepatitis C at baseline (adjusted hazard ratio [HR] 2.76, 95% CI 1.47-5.16), previous attempted suicide (adjusted HR 1.88, 95% CI 1.01-3.50) and recent overdose (adjusted HR 2.85, 95% CI 1.00-8.09). INTERPRETATION: Young Indigenous people using drugs in BC are dying at an alarming rate, particularly young women and those using injection drugs. These deaths likely reflect complex intersections of historical and present-day injustices, substance use and barriers to care.

The Cedar Project WelTel mHealth intervention for HIV prevention in young Indigenous people who use illicit drugs: study protocol for a randomized controlled trial.

BACKGROUND: Despite successes in preventing and treating HIV, Indigenous people in Canada continue to face disproportionately high rates of HIV infection. Programs that support healing from lifetime trauma, support connection to culture, and reduce drug-related harms are critical to preventing HIV among young Indigenous people who use drugs. The Cedar Project WelTel mHealth intervention proposed here is a structured mobile-phone initiative to connect young Indigenous people who use drugs with Cedar Case Managers in a community-based setting. The intervention consists of a package of supports, including a mobile phone and cellular plan, weekly two-way text messaging, and support from Cedar Case Managers. METHODS: The Cedar Project WelTel mHealth study is a multi-site Zelen pre-randomized trial to measure the effect of a two-way supportive text-message intervention to reduce HIV vulnerability among young Indigenous people who use illicit drugs in two Canadian cities. The trial is nested within the Cedar Project, an ongoing cohort study addressing HIV and hepatitis C vulnerability among young Indigenous people who use drugs in Vancouver and Prince George, British Columbia. The Cedar Project Partnership, an independent body of Indigenous Elders, leaders, and health/social service experts, governs all aspects of the study. Two hundred participants will be followed over a 16-month period, with HIV propensity score at 6 months as the primary outcome. Secondary outcomes include HIV propensity at 1 year, HIV risk, resilience, psychological distress, access to drug-related services, and connection to culture measured at 6 months and 1 year. Primary analysis is by intention to treat. DISCUSSION: Culturally safe interventions that address barriers to HIV prevention while supporting the strength of young Indigenous people who use drugs are urgently needed. Despite presenting a tremendous opportunity to connect young, highly transient Indigenous people who use drugs to prevention services, supportive two-way mHealth programs have yet to be tested for HIV prevention in a community-based setting with this population. TRIAL REGISTRATION: ClinicalTrials.gov NCT02437123 https://clinicaltrials.gov/show/NCT02437123 (registered 4 May 2015). Protocol version: 24 July 2015.

The Cedar Project: Negative health outcomes associated with involvement in the child welfare system among young Indigenous people who use injection and non-injection drugs in two Canadian cities.

OBJECTIVES: Indigenous 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. METHODS: The 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. RESULTS: Of 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. CONCLUSION: This 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.

The Cedar Project: resilience in the face of HIV vulnerability within a cohort study involving young Indigenous people who use drugs in three Canadian cities.

BACKGROUND: Indigenous scholars have long argued that it is critical for researchers to identify factors related to cultural connectedness that may protect against HIV and hepatitis C infection and buffer the effects of historical and lifetime trauma among young Indigenous peoples. To our knowledge, no previous epidemiological studies have explored the effect of historical and lifetime traumas, cultural connectedness, and risk factors on resilience among young, urban Indigenous people who use drugs. METHODS: This study explored risk and protective factors associated with resilience among participants of the Cedar Project, a cohort study involving young Indigenous peoples who use illicit drugs in three cities in British Columbia, Canada. We utilized the Connor-Davidson Resilience Scale to measure resilience, the Childhood Trauma Questionnaire to measure childhood maltreatment, and the Symptom-Checklist 90-Revised to measure psychological distress among study participants. Multivariate linear mixed effects models (LME) estimated the effect of study variables on mean change in resilience scores between 2011-2012. RESULTS: Among 191 participants, 92 % had experienced any form of childhood maltreatment, 48 % had a parent who attended residential school, and 71 % had been in foster care. The overall mean resilience score was 62.04, with no differences between the young men and women (p = 0.871). Adjusted factors associated with higher mean resilience scores included having grown up in a family that often/always lived by traditional culture (B = 7.70, p = 0.004) and had often/always spoken their traditional language at home (B = 10.52, p < 0.001). Currently knowing how to speak a traditional language (B = 13.06, p = 0.001), currently often or always living by traditional culture (B = 6.50, p = 0.025), and having recently sought drug/alcohol treatment (B = 4.84, p = 0.036) were also significantly associated with higher mean resilience scores. Adjusted factors associated with diminished mean resilience scores included severe childhood emotional neglect (B = -13.34, p = 0.001), smoking crack daily (B = -5.42, p = 0.044), having been sexual assaulted (B = 14.42, p = 0.041), and blackout drinking (B = -6.19, p = 0.027). CONCLUSIONS: Young people in this study have faced multiple complex challenges to their strength. However, cultural foundations continue to function as buffers that protect young Indigenous people from severe health outcomes, including vulnerability to HIV and HCV infection.

The Cedar Project: Residential transience and HIV vulnerability among young Aboriginal people who use drugs.

Aboriginal homelessness is considered to be a result of historic dispossession of traditional territories and forced displacement from community structures. Using data collected from 2005-2010 from the Cedar Project, a cohort of young Aboriginal people who use drugs in two Canadian cities, we examined how residential transience shapes HIV vulnerability. At baseline, 48 of 260 participants (18.5%) reported sleeping in six or more places ('highly transient') in the past six months. Generalized linear mixed models identified associations between high transience and sex and drug related HIV vulnerabilities. Transience was independently associated with sex work (AOR:3.52, 95%CI:2.06, 6.05); sexual assault (AOR:2.48, 95%CI:1.26, 4.86); injection drug use (AOR:4.54, 95%CI:2.71, 7.61); daily cocaine injection (AOR:2.16, 95%CI:1.26, 3.72); and public injection (AOR:2.87, 95%CI:1.65, 5.00). After stratification, transience and sexual vulnerability remained significantly associated among women but not men. Ensuring that young Aboriginal people have access to safe spaces to live, work, and inject must include policies addressing residential transience as well as the absence of a roof and walls.

The Cedar Project * : historical trauma and vulnerability to sexual assault among young aboriginal women who use illicit drugs in two Canadian cities.

This study explored trends of sexual assault and associated risk factors within a cohort of young Aboriginal women who used drugs in Vancouver and Prince George, Canada, between 2003 and 2010. Results demonstrated no change in the trend of sexual assault over time; however, odds of sexual assault were significantly higher for women who had at least one parent who attended residential school, had experienced childhood sexual abuse, were involved in sex work, had been offered money to not use condoms, had used injection drugs, had injected cocaine and opiates daily, had binged with injection drugs, and had difficulty accessing clean syringes. Findings highlight the urgency of interventions addressing the complexity of risk and opportunities for healing.

HIV vulnerabilities and coercive sex at same-sex sexual debut among men who have sex with men in Beijing, China.

Few studies have examined coercive sex and HIV vulnerabilities among men who have sex with men (MSM) in China. The present study seeks to compare individual characteristics between MSM who did and did not experience coercive sex at their MSM sexual debut and to identify HIV risk factors correlated with coercive sex at MSM sexual debut. In 2007, we recruited 167 MSM in Beijing, China by peer-referred social network sampling. Each participant then completed self-administered questionnaires regarding their sexual experiences and practices. Results show that 14% of participants reported coercive sex at MSM sexual debut, of whom 48% reported recent unprotected anal intercourse (UAI). Coercive sex at MSM sexual debut was significantly associated with UAI [adjusted odds ratio (AOR): 5.38, 95% confidence interval: 1.95-14.87] and lifetime number of male sex partners (AOR: 7.25, 95% CI: 2.39-22.01). Coercive sex is harming MSM in China and should be immediately addressed by researchers, public health officials, and MSM community stakeholders.

The Cedar Project: impacts of policing among young Aboriginal people who use injection and non-injection drugs in British Columbia, Canada.

BACKGROUND: Policing has profound health implications for people who use illicit drugs. Among Aboriginal communities, distrust of police is common, due partly to legacies of colonial policing. In response to the paucity of research among Aboriginal people who use drugs, this paper aims to: (1) Describe the policing experiences of young Aboriginal people who use drugs; (2) Identify policing activities associated with unsafe injection practices; and (3) Elucidate barriers to positive police relations. METHODS: The Cedar Project is a cohort study involving young Aboriginal people in Vancouver and Prince George, British Columbia, who use illicit drugs. This mixed-methods study (N=372) used period prevalence from 2007 to 2010 to describe policing experiences, mixed effects regression models to identify correlates of policing activities, and thematic qualitative analysis to assess attitudes to police relations. RESULTS: Many participants were stopped by police (73%), experienced physical force by police (28%), had drug equipment confiscated (31%), and changed location of drug use because of police (43%). Participants who reported dealing drugs (40%) were significantly more likely to experience police engagement. Among participants in Prince George, 4% reported to have had non-consensual sex with members of the criminal justice system. Policing activity was significantly associated with syringe sharing, rushed injection, and reused syringe. Due to personal experience, practical concerns, and intergenerational legacies of unfair policing practices, most participants did not want a positive relationship with police (57%). Desire for a positive relationship with police was directly associated with being helped by police, and inversely associated with being stopped by police and experiencing physical force by police. CONCLUSION: Policing activities may be impacting the well-being of Aboriginal people who use drugs. Due to focused prosecution of street-level drug dealing, some police may favor enforcement over harm reduction. Positive police engagement and less aggressive policing may enhance perceptions of police among young Aboriginal people who use drugs.
