Associations of daily step counts with depressive symptoms during pregnancy: Ruian birth cohort study.
Article in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundAlthough studies have shown that physical activity may have protective effects against depression during pregnancy, evidence on the role of objectively measured physical activity remains limited. This study aimed to explore the associations between daily step counts in the second trimester and depressive symptoms at different stages of pregnancy.
methodsBased on 828 pregnant women from the Ruian Birth Cohort Study, daily step counts were averaged over a week from WeChat records in the second trimester. Linear and logistic regression models were used to evaluate associations of daily step counts in the second trimester with Edinburgh Postnatal Depression Scale (EPDS) scores and clinically significant depressive symptoms (EPDS scores ≥ 10) in the second and third trimesters, respectively.
resultsThe 828 pregnant women took an average of 3,840 (± 2,170) steps each day in the second trimester. Higher daily step counts were associated with lower EPDS scores in both the second (a unit of 1000 steps; β: -0.16, 95% CI: -0.30 to -0.03) and third trimesters (β: -0.25, 95% CI: -0.40 to -0.10). Additionally, higher step counts correlated with lower odds of clinically significant depressive symptoms in the third trimester (OR: 0.88, 95% CI: 0.79 to 0.96). The benefits were consistent across weekends and workdays.
conclusionDistinct patterns of association between second-trimester daily step counts and depressive symptoms in the second and third trimesters highlight the potential mental health benefits of maintaining higher daily step counts. The accessibility and high user engagement make daily step counts as a particularly practical tool for monitoring physical activity during pregnancy.
