Polysocial risk factors and trajectories of antenatal moderate-to-severe depressive symptoms: a retrospective cohort study in Shenzhen, China.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAntenatal depression, especially moderate-to-severe depression, is associated with adverse maternal and infant health outcomes and is affected by multiple psychosocial factors. However, the cumulative effects of psychosocial determinants and trajectories of antenatal depression are underappreciated. This study aimed to investigate the cumulative effects of various psychosocial determinants on antenatal moderate-to-severe depressive symptoms (MSD) based on the polysocial risk score (PsRS), to identify trajectories of MSD based on group-based trajectory modeling (GBTM), and to explore the association between the PsRS and diverse trajectories.
methodsA retrospective cohort study was conducted among 21,336 pregnant women in Shenzhen, China, from 2020 to 2023. Antenatal depressive symptoms were assessed by the Patient Health Questionnaire-9 (PHQ-9) across three pregnancy trimesters. The PsRS was selected and calculated by counting established social determinants from four social risk domains, including socioeconomic status, lifestyle behaviors, psychosocial factors, and living conditions. GBTM was employed to identify distinct trajectories of depressive symptoms. Multinomial logistic regression investigated the relationship between PsRS and diverse trajectories.
resultsOf women, 9.1% experienced at least one episode of MSD across three pregnancy trimesters. An intermediate PsRS and a high PsRS were associated with higher risks of MSD during pregnancy, with the adjusted hazard ratios being 1.99 (95% CI, 1.71-2.31) and 4.44 (95% CI, 3.81-5.17), respectively, compared with those with a low PsRS. GBTM identified five distinct trajectories of antenatal depressive symptoms: persistent MSD, resolving MSD, chronic mild, resolving mild, and no depressive symptoms. Above all trajectories, persistent MSD demonstrated the highest PSRS scores and risk gradients.
conclusionsThis study provides a practical basis for integrating early polysocial risk screening into routine prenatal care, enabling the timely identification and targeted support of high-risk pregnant women. These findings underscore the need for incorporating comprehensive social risk assessment into maternal health policies and intervention programs to improve mental health outcomes across pregnancy.
