Cesarean Section and Postpartum Depression in a Cohort of Chinese Women with a High Cesarean Delivery Rate
Bibliographic record
Abstract
BACKGROUND: Whether or not cesarean delivery is associated with increased risk of postpartum depression (PPD) remains unclear. METHODS: We carried out a prospective cohort study between February and September 2007 in Hunan Maternal and Infant Hospital and the First Affiliated and Third Affiliated Hospitals of the Central South University in Changsha, Hunan, People's Republic of China. The Chinese version of the Edinburgh Postnatal Depression Scale (EPDS) was used at 2 weeks postpartum to assess PPD, with a score of ≥13 as the cutoff for PPD. RESULTS: A total of 534 women were included in the final analysis, with 415 (77.7%) delivering by cesarean section (the majority of them with no medical indication). The rate of PPD was 21.7% in women who had a cesarean delivery and 10.9% in women who delivered vaginally. The increased risk of PPD in women who had cesarean sections was maintained after we adjusted for potential confounding factors or considered cesarean delivery by social indications. CONCLUSIONS: Cesarean section is associated with increased risk of PPD in Chinese women with a high cesarean delivery rate.

How this classification was reachedexpand
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.
