A trajectory analysis of childhood motor development following stress in pregnancy: The QF2011 flood study
Bibliographic record
Abstract
This prospective, longitudinal cohort study examined the effects of flood-related stress in pregnancy on the trajectory of children's motor development; and the moderating effects of gestational timing of the flood or sex of the child. Women who were pregnant during a severe flood reported on their objective flood-related experiences, emotional reactions, and cognitive appraisal of the disaster. At 2-, 6-, 16-months, 2½- and 4-years postpartum, mothers' assessed their children's fine and gross motor development using the Ages and Stages-3 Questionnaire. High objective flood-exposure, or a negative appraisal, especially in later pregnancy, predicted poorer gross motor skills which rapidly improved across early childhood. Children's fine motor skill was influenced by the sex of the child with improvements in girls' fine motor skills over time, but not boys'. This demonstrates that stress in pregnancy has enduring influences on gross, but not fine, motor skills. Results are discussed in relation to fetal programming and stress appraisal theory.

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.
