The Cedar Project: Methadone maintenance treatment among young Aboriginal people who use opioids in two Canadian cities
Bibliographic record
Abstract
INTRODUCTION AND AIMS: The Cedar Project is a community-based study aiming to identify variables associated with ever being on methadone maintenance treatment (MMT) among young Aboriginal people using drugs and to discuss possible barriers to MMT in this population. DESIGN AND METHODS: This is a prospective cohort study with recruitment by health-care providers, outreach, and word of mouth in Vancouver and Prince George. Participants included 605 Aboriginal participants who were age 14-30 years, reported illicit drug use in the month prior to enrolment, and provided written informed consent. Variables associated with ever being on MMT were analysed through χ(2) -testing and multivariate logistic regression, limited to people reporting opioid use (n = 397). RESULTS: Less than half of participants reporting daily injection of opioids had ever been on MMT. In adjusted multivariate logistic regression analyses, older age [odds ratio (OR) 1.17; 95% confidence interval (CI) 1.08-1.28)]; female gender (OR 3.76; 95% CI 2.00-7.07); hepatitis C antibody positivity (OR 2.76; 95% CI 1.53-4.95); and daily opioid injection (OR 2.59; 95% CI 1.46-4.61) were positively associated with ever being on MMT. Weekly or more alcohol use (OR 0.43; 95% CI 0.21-0.87) was negatively associated with ever being on MMT. DISCUSSION AND CONCLUSION: MMT access by young Aboriginal people is low. The associations between MMT use and other variables need further study to steer efforts directed at recruitment into MMT. The removal of barriers to MMT and inclusion of young Aboriginal people in the development of treatment programs based on Indigenous values are urgently required to help Aboriginal people who use drugs.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
