Impact of employment on maternal mental health during pregnancy: evidence from a Korean prospective cohort.
Article in BMC pregnancy and childbirth, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundPregnancy increases vulnerability to mental health challenges. We investigated stage-specific associations of employment with maternal depression, anxiety, and stress, and whether household income moderates these relationships.
methodsWe analyzed data from the prospective Korean Pregnancy Outcome Study (n = 3,405). Employment and mental health outcomes—depression, anxiety, and stress—were assessed during the first, second, and third trimesters. Logistic regression calculated adjusted odds ratios (aORs), controlling for confounders including history of depression and physical health status to rigorously address the healthy worker effect.
resultsEmployment was significantly associated with reduced depression at all visits (aORs 0.68–0.76) but showed no significant association with anxiety. Regarding stress, employed women experienced higher risks initially, but this difference attenuated by the third trimester. Women maintaining employment through the third trimester had a significantly lower risk of depression (aOR 0.64) compared to women without employment across all visits. Notably, maintaining employment only up to the first trimester showed comparable benefits. Subgroup analyses indicated a stronger association between employment and depression among high-income women, showing a borderline significant interaction in the first trimester.
conclusionsEmployment was consistently associated with reduced depression, but not anxiety, independent of physical health. While employed women initially faced higher stress, this subsided over time. Psychosocial benefits of the worker role may buffer against depression, particularly for high-income women. Maintaining employment, at least through the first trimester, may offer meaningful mental health benefits. However, causality cannot be inferred.
