Prevalence of suicidal thoughts and behaviors among young adults between 2000 and 2021: Results from six national representative surveys in France
Bibliographic record
Abstract
The study examines the prevalence of 12-month suicidal thoughts and lifetime suicide behaviors among young adults between 2000 and 2021. Data were drawn from the Health Barometer survey, a cross-sectional survey on a French national representative sample. The 2000, 2005, 2010, 2014, 2017, and 2021 survey waves were pooled to examine time trends in 12-month suicidal thoughts and lifetime suicidal behaviors among respondents aged 18 to 25 (n = 13,326), categorized based on sex and on their occupational status: students, those employed, and those who are neither in employment, education or training (NEETs). The 12-month prevalence of suicidal ideation among young adults in 2021 (6.8 %) is no different from that of 2000 (7.0 %), despite a U-shape curve in between. In contrast, the overall prevalence of lifetime suicide attempts was significantly higher in 2021 as compared to what was observed on average in the previous 21 years. In multivariate models, females and NEETs were overall at greatest risk for suicidal ideation and suicidal behaviors. Additional attention and prevention efforts are needed to reach young adults who are neither in employment, education or training.

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.
