Young Adult Outcomes Associated With Adolescent Suicidality: A Meta-analysis
Bibliographic record
Abstract
CONTEXT: Suicide is one of the leading causes of death among adolescents worldwide. Adolescents who present with suicidality may be at an increased risk for future mental illness and suicidality in young adulthood. OBJECTIVE: The objective of this study was to systematically assess the relationship between adolescent suicidal ideation and suicide attempts (suicidality) and young adult psychopathological outcomes. DATA SOURCES: Medline, Embase, and PsychInfo (OVID Interface) were searched for articles published before August 2021. STUDY SELECTION: Included articles were prospective cohort studies that compared young adult (19-30 years) psychopathological outcomes between suicidal and nonsuicidal adolescents. DATA EXTRACTION: We extracted data related to suicidality in adolescence, mental health outcomes in young adulthood, and covariates. Outcomes were analyzed via random-effect meta-analyses and reported using odds ratios. RESULTS: Of 9401 references screened, we included 12 articles comprising over 25 000 adolescents. Four outcomes were meta-analyzed: depression, anxiety, suicidal ideation, and suicide attempt. Adjusted meta-analyses showed that adolescent suicidal ideation was associated with young adult suicide attempt (odds ratio [OR] = 2.75, 95% confidence interval [CI]:1.70-4.44), depressive disorders (OR = 1.58, 95% CI: 1.20-2.08), and anxiety disorders (OR = 1.41, 95% CI: 1.01-1.96), whereas adolescent suicide attempts were associated with young adult suicide attempt (OR = 5.71, 95% CI: 2.40-13.61), and young adult anxiety disorders (OR = 1.54, 95% CI: 1.01-2.34). Results for young adult substance use disorders were mixed. LIMITATIONS: Significant heterogeneity between studies was observed because of differences in timing, method of assessments, and covariate adjustment. CONCLUSIONS: Adolescents experiencing suicidal ideation or with a history of suicide attempt may have increased odds of further suicidality or mental disorders in young adulthood.

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.
