Psychosocial predictors of labor/ delivery complications and infant birth weight: A prospective multivariate study
Bibliographic record
Abstract
Using a multidimensional approach to measure stress, this study prospectively examined the influence of maternal stress, social support and coping styles on labor/delivery complications and infant birth weight. Beginning in the third month of pregnancy, stress was assessed monthly. In each trimester, data on social support, coping strategies, lifestyle behaviors and pregnancy progress were collected. One month following delivery, information on labor, delivery and infant status was obtained. The final sample consisted of 80 women. The results demonstrated that women who experienced greater stress during pregnancy had a more difficult labor/delivery, even after controlling for parity. Younger maternal age was also linked with intrapartum complications. Perceived prenatal social support emerged as a predictor of infant birth weight. Women who reported less satisfaction with their social support in the second trimester gave birth to infants of lower birth weight. The results suggest an association between specific psychosocial variables and negative birth outcomes.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
