The Impact of Perceived Maternal Stress and Other Psychosocial Risk Factors on Pregnancy Complications
Bibliographic record
Abstract
Complications of pregnancy are usually attributed to biomedical risk factors. There is circumstantial evidence that some psychosocial factors also contribute to preterm birth, gestational hypertension or preeclampsia, intrauterine growth restriction, and other pregnancy-related complications. This prospective longitudinal cohort study investigated the effect of perceived maternal stress and other psychosocial profile components on complications of pregnancy among a population of women carrying singleton pregnancies at a tertiary perinatal center. Six different dimensions of the psychosocial profile were assessed during gestation using self-administered questionnaires completed at either 10 to 20 weeks' gestation or 25 to 30 weeks' gestation. The effect of these psychological risk factors between groups with or without complication was evaluated by analysis of variance with repeated measures. Individual dimensions assessed for possible associations with adverse antenatal, perinatal, and neonatal outcomes included maternal perceived stress, psychological distress, daily hassles during pregnancy, locus of control (pregnancy beliefs scale), childhood trauma, and social support. Among the 303 expectant mothers, 81 (26.7%) had at least 1 pregnancy complication. There were no significant differences in the occurrence of biomedical risk factors between groups with or without a pregnancy complication. The level of perceived stress at 10 to 20 weeks was higher among women with pregnancy complications compared with those with an uneventful term pregnancy (32.6 ± 11.7 vs. 29.3 ± 10.3; P < 0.05). Analysis of individual adverse outcomes showed that women with preterm birth perceived even more stress at 10 to 20 weeks of gestation than the women with uneventful term pregnancy (34.4 ± 11.5 vs. 29.3 ± 10.3; P < 0.05). Women with a complication reported less peer social support at 25 to 30 weeks of gestation compared with those with uneventful term pregnancy (51.0 ± 16.6 vs. 55.5 ± 13.8; P < 0.05). There was no significant difference between the groups for other psychosocial dimensions. These findings suggest that perceived stress before 20 weeks of gestation is associated with pregnancy complications, especially preterm birth.

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.
