The prenatal anxiety trajectory and its correlation with stress and psychological flexibility: a longitudinal study.
Article in BMC psychology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundSeveral investigations have delved into the heterogeneity of anxiety symptom trajectories throughout pregnancy. However, the causal relationships between prenatal anxiety, stress, and psychological flexibility remain unclear. This study endeavored to identify distinct trajectory groups and influencing factors for anxiety symptoms in pregnant women, and explore the relationship between stress, psychological flexibility, and anxiety during this period.
methodsPregnant women were recruited from March to May 2022 at a hospital in Xi'an City, Shaanxi Province, China. Structured questionnaire surveys were conducted through a WeChat applet at five time points (12, 20, 26, 32, and 37 weeks), collecting information on basic demographics, stress, psychological flexibility, and anxiety throughout their pregnancies. The latent class growth model was employed to identify potential trajectory groups of prenatal anxiety, logistic regression was utilized to analyze the factors associated with these groups, and a linear mixed model was implemented to investigate the relationship between stress, psychological flexibility, and anxiety.
resultsThree distinct anxiety trajectory groups were identified. Unplanned pregnancy (OR = 1.76, 95% CI: 1.08-2.87, P = 0.024) and a history of spontaneous abortion (OR = 1.75, 95% CI: 1.10-2.79, P = 0.018) were significantly associated with a heightened risk of developing an anxiety trajectory group. Higher stress at 12 (β = 0.229, 95% CI: 0.187-0.271), 20 (β = 0.249, 95% CI: 0.211-0.287), 26 (β = 0.255, 95% CI: 0.213-0.296), and 32 weeks(β = 0.278, 95% CI: 0.241-0.315) significantly predicted elevated anxiety in late pregnancy (all P < 0.001). While higher psychological flexibility at the same time points predicted lower anxiety (βs from - 0.074 to - 0.099; all P < 0.001).
conclusionsThe trajectories of prenatal anxiety symptoms are dynamic and heterogeneous, with stress and psychological flexibility emerging as significant predictive factors. This study offers critical insights into the characteristics of pregnant women in high-risk trajectory groups, highlighting the potential for early intervention to mitigate worsening symptoms.
