Abstract

fetched live from OpenAlex

BackgroundMore than one in five women deal with a psychiatric disorder during the perinatal period. Whereas perinatal depression is well documented, there is still little research on the full range of perinatal psychiatric disorders and their clinical evolution across this whole period. The present study investigated the susceptibility to psychiatric illness during pregnancy and up to one year postpartum. We aimed to identify the most frequent disorders and comorbidities arising in each perinatal period. We outlined the clinical trajectories of these disorders in terms of evolution across past history, pregnancy and postpartum.MethodThrough a retrospective longitudinal design, data were collected in 2019-2020 from the medical records of the cohort of 964 women who required care in a tertiary perinatal psychiatry clinic located in Quebec City (Canada) between 2004 and 2020. Incidence rates of the full range of psychiatric disorders were estimated per period and their evolution across time identified clinical trajectories.ResultsDuring pregnancy, 34 different disorders were newly diagnosed with incidence rates ranging from 0.1% to 15.5% (45.6% of women having had at least one disorder diagnosed during pregnancy) whereas, during postpartum, 36 disorders were newly diagnosed with incidence rates ranging from 0.1% to 31.0% (67.5% of women having had at least one disorder diagnosed during postpartum). For most disorders, rates were significantly higher in postpartum than in pregnancy. A woman could develop multiple disorders during a given perinatal period: this comorbidity involved various combinations of diagnoses in 28% of women during pregnancy and 38% during postpartum. We outlined 52 different clinical trajectories from past history to postpartum, underlining the heterogeneity of the perinatal course.ConclusionsPregnancy is a susceptible period for women with past psychiatric histories whereas postpartum could trigger a new illness in women without a past history or pregnancy-onset psychiatric disorder.

Not 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.
