Association between pre-pregnancy maternal stress and small for gestational age: a population-based retrospective cohort study.
Article in BMC medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundMaternal stress is a potential factor affecting fetal growth, but it is unknown whether it directly affects fetal growth restriction. This study aims to investigate the association between pre-pregnancy maternal stress with small for gestational age (SGA).
methodsThis study used a population-based retrospective cohort analysis to examine the association between pre-pregnancy maternal stress and SGA in offspring. Data were extracted from the National Preconception Health Care Project (NPHCP), conducted between 2010 and 2012, which encompassed preconception health-related information from 572,989 individuals across various regions in China. Logistic regression models were used to assess the associations between pre-pregnancy maternal stress variables and the risk of SGA. In addition, Synthetic Minority Over-sampling Technique (SMOTE) and Propensity Scores (PS) methods were used to enhance the model's ability to the associations between pre-pregnancy maternal stress and SGA.
resultsPre-pregnancy maternal stress was significantly associated with an increased the risk of SGA in offspring (OR 1.35, 95% CI 1.20 to 1.51, P < 0.001). Stress related to life and economic factors notably increased the risk of SGA across different socio-economic conditions, whereas stress related to friends did not show a statistically significant association (P > 0.05). Specially, individuals with lower socio-economic status that characterized by below high school education levels (OR = 1.45, 95% CI: 1.23 to 1.70), farmer occupation (OR = 1.33, 95% CI: 1.15 to 1.55, P = 0.002), rural residence (OR = 1.38, 95% CI: 1.22 to 1.56, P < 0.001), and younger age (under 35 years: OR = 1.35, 95% CI: 1.20 to 1.52, P < 0.001) were more susceptible to pre-pregnancy maternal stress, increasing their risk of SGA.
conclusionsPre-pregnancy maternal stress was positively associated with an increased risk of SGA in offspring. Individuals with lower socio-economic status were more likely to experience pre-pregnancy maternal stress related to life and economic factors, which in turn contributed to a higher risk of SGA.
