Association between Binge Drug use and Suicide Attempt among People who Inject Drugs
Bibliographic record
Abstract
BACKGROUND: People who inject drugs (PWID) have an elevated risk of suicide attempt. Although different substances are associated with suicide attempt, the overall risk posed by binge behavior, a high-risk pattern of drug use, remains unclear. The objective of this study is to assess the association between binge drug use and suicide attempt in a prospective cohort of PWID in Montreal, Canada. METHODS: Participants answered a biannual interviewer-administered questionnaire compiling information on sociodemographics, pattern of substance use (cocaine, amphetamine, opioids, sedative-hypnotics, alcohol, and cannabis), and psychosocial stressors and related markers. The relationship between suicide attempt and binge behavior was modeled using generalized estimating equations (GEEs), controlling for type and pattern of substance use, sociodemographic characteristics, and significant mental health markers. RESULTS: Among 1240 participants (mean age ± SD: 38.2 ± 9.8) at baseline, 222 (17.9%) reported binge during the past 6-months. PWID reporting binge were significantly younger (P < .001), less educated (P = .012), less likely male (P = .047), and had shorter history of injection (P < .001). In addition, they were younger at first injection (P = .014), reported higher rates of prostitution and psychological disorders (P = .003), and were more likely to use other drugs except cannabis and alcohol. Binge was independently associated with attempted suicide in the GEE multivariate model (adjusted odds ratio [aOR 95% CI] = 1.91 [1.38-2.65], P < .001). CONCLUSIONS: Among PWID at high risk of suicide attempt, those who binge represent a particularly vulnerable subgroup. Although the exact mechanisms underlying this finding remain unresolved, several hypothesis pertaining to the neurobiological and psychosocial consequences of binge, as well as common personality traits, warrant further investigations.

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.
