Life course socioeconomic position and major depression in Canada
Bibliographic record
Abstract
Early-life socioeconomic position (SEP) contributes to disease risk in adults, however, there is mixed evidence for the role of early-life SEP in adult depression.Using logistic regression analysis we explore whether parents" education influences the risk for major depressive episode (MDE) independent of other early-life and adult risk factors.Data are from the first seven waves of the Canadian National Population Health Survey (1994/95 to 2006/07), and include 1,267 participants that were aged 12 to 24 at wave one.Father"s education has no effect.Respondents of mothers with less than secondary school are at increased risk for MDE (OR: 2.04, 95% CI: 1.25, 3.32) compared to respondents of more educated mothers.Adjusting for the respondent"s adverse childhood experiences, SEP, psychosocial factors, and physical health does not reduce the impact of maternal education.These results suggest that maternal education may play a significant role in the aetiology of adult depression.

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.
