Morbidity, Suicidal Ideation and Suicide Attempts Among Youth in Canada: A Nationally-Representative Study: Morbidité, idées suicidaires et tentatives de suicide chez les jeunes au Canada : Une étude représentative à l’échelle nationale
Bibliographic record
Abstract
BACKGROUND: Suicide is a leading cause of mortality among youth globally. Evidence suggests that individuals with physical illness, mental illness, or neurodevelopmental disorders are at increased risk of suicide. However, few studies have estimated the prevalence of suicidal ideation and suicide attempts among youth with compounding health burdens. The purpose of this study is to estimate the prevalence of suicidal ideation and suicide attempts and their associations across morbidity status among youth in Canada. METHODS: Data come from 6,915 youth aged 15-17 years (49% female) enrolled in the 2019 Canadian Health Survey on Children and Youth. The person most knowledgeable or the youth themselves provided responses regarding sociodemographic characteristics, morbidity status, and indicators of suicide. The prevalence of suicidal ideation (past year) and suicide attempts (lifetime) were compared across morbidities (none, physical illness only, mental illness only, neurodevelopmental disorder only, and multimorbidity). Logistic regression models estimated adjusted associations between morbidity status and suicidal behaviour. RESULTS: Suicidal ideation and suicide attempts were most commonly reported by youth with mental illness only (32%, 18%) and multimorbidity (28%, 19%). While all morbidities were associated with indicators of suicide, the strongest association was found between multimorbidity and suicide attempts odds ratio = 5.2 (3.4, 8.0). CONCLUSIONS: These contemporary estimates of youth in Canada suggest that suicidal ideation and suicide attempts are common and reinforce the need for integrated physical and mental health services for youth with multimorbidity to reduce the incidence. Research investigating causal mechanisms of the intersections between physical illness, mental illness, neurodevelopmental disorders, and suicide is needed.Plain Language Summary Title:Morbidity, suicidal ideation and suicide attempts among youth in Canada.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
