The association between maternal distress and serum cortisol levels in children : differential outcomes by asthma diagnosis
Bibliographic record
Abstract
Both asthma and exposure to maternal distress have been shown to correlate with altered cortisol levels in children, but my investigation of the relationship among all three variables appears to be a first.Using a representative sample (n: 503) of the 1995 Manitoba birth cohort, children's serum cortisol levels were examined in relationship to exposure to maternal distress and asthma status.A multiple linear regression analysis confirmed my hypothesis of a statistically significant interaction between childhood asthma and exposure to maternal distress in relation to children's seÍum cortisol levels.As predicted, non-asthmatic children exposed to recurrent maternal distress responded to an acute stressor with elevated cortisol levels whereas children with asthma responded with blunted cortisol levels.My results reinforce the need for mandatory postnatal screening of new mothers through programs such as Manitoba's Families First, which help at risk families in caring for their newborns and may prevent the dysregulation of children's stress response systems as well as conditions such as childhood asthma.

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.
