The Associations between Health Risk Behaviours and Suicidal Ideation and Attempts in a Nationally Representative Sample of Young Adolescents
Bibliographic record
Abstract
OBJECTIVE: To examine associations between health risk behaviours and suicidal ideation and attempts in Canadian adolescents aged 12 to 13 years. Young adolescents think about and attempt suicide. However, most existing research on suicide has been conducted on individuals aged 15 years and older. METHOD: The present study examined a nationally representative Canadian sample of adolescents aged 12 to 13 years (n=2090). Health risk behaviours included disruptive (shoplifting, physical fighting, damaging property, fighting with a weapon, carrying a knife, and gambling), sexual (petting below the waist and sexual intercourse), and substance use behaviours (smoking cigarettes, consuming alcohol, marijuana or hash, and glue or solvents). Unadjusted and adjusted (for all significant health risk behaviour and psychiatric symptoms) models were tested. RESULTS: All health risk behaviours were common among male and female adolescents. In unadjusted models, almost all health risk behaviours were associated with suicidal ideation and attempts among adolescent boys. In adjusted models, only damaging property, sexual intercourse, and smoking cigarettes remained statistically associated with suicidal ideation, while smoking cigarettes and using marijuana or hash remained statistically associated with suicide attempts among adolescent boys. All health risk behaviours were statistically associated with suicidal ideation and attempts among female adolescents in unadjusted models. In adjusted models, only carrying a knife remained statistically associated with suicidal ideation, while shoplifting and gambling remained statistically associated with suicide attempts among adolescent girls. CONCLUSIONS: Health risk behaviours among young adolescents are associated with suicidal ideation and attempts among young adolescents. Recognizing health risk behaviours among young adolescents may be one means of understanding who among them is at increased risk of suicidality.

How this classification was reachedexpand
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.
