The Effects of Episodic Versus Continuous and Major Versus Mild Depression and Anxiety Symptoms on Pregnancy and Labour Complications
Bibliographic record
Abstract
Background: Depression occurs in approximately 20% of pregnant women, with up to 25% experiencing anxiety.Various pregnancy and labour complications have been associated with maternal mood problems.Methods: This population study of antenatal and early postpartum depression and maternal, child outcomes involved 649 women assessed three times: the second trimester, the third trimester, and in the early postpartum.Our objective was to determine the occurrence and outcomes on pregnancy and labour of major and mild depression.Results: Major depression in the second trimester was significantly associated with developing gestational diabetes and swelling/edema.Major depression that occurred continuously throughout pregnancy was significantly associated with induced labour and antenatal bleeding/abruption.Mild depression in the second trimester was significantly associated with antenatal bleeding/abruption and premature rupture of the membranes.Mild depression in the third trimester was associated with caesarean birth.Mild depression that occurred continuously throughout pregnancy was significantly associated with the use of vacuum/forceps or operative delivery.

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.
