Anxiety in pregnancy complicated by gestational and pre-gestational diabetes: a systematic review and meta-analysis.
Synthesis 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
backgroundGestational diabetes mellitus (GDM) and pregestational diabetes mellitus (pre-GDM) affect approximately 20% of pregnancies worldwide, requiring intensive management, alongside pregnancy-related concerns and broader psychosocial factors, all of which may contribute to increased psychological distress. While anxiety is associated with adverse maternal and child outcomes, evidence in women with diabetes during pregnancy remains fragmented. This systematic review and meta-analysis examined anxiety in pregnant and postpartum women with GDM and pre-GDM.
methodsThis study searched MEDLINE, Scopus, Embase, EBSCO, Cochrane Library, ClinicalTrials.gov, and WHO ICTRP from inception to April 2025. Observational studies reporting anxiety outcomes in pregnant or postpartum women with GDM or pre-GDM were included. Two reviewers independently screened articles, extracted data, and assessed quality using the JBI Critical Appraisal Checklists. Random-effects meta-analyses were performed, with subgroup analyses by region and measurement instrument. Meta-regression explored heterogeneity sources. The study followed PRISMA 2020 and was prospectively registered in PROSPERO (CRD420251063824).
resultsThirty-four studies (n = 994,189; 38,584 GDM; 156 pre-GDM; 955,449 healthy controls) were included. Women with GDM had higher odds of antenatal anxiety than healthy controls (OR = 1.69, 95% CI: 1.20-2.37) and higher mean anxiety scores (SMD = 0.21, 95% CI: 0.07-0.34). Among eight single-arm studies reporting the prevalence of screen-positive antenatal anxiety in women with GDM, all conducted in Asia, the pooled prevalence was 36% (95% CI: 22-50%); however, this estimate should be interpreted very cautiously because of extreme heterogeneity (I
conclusionsA high burden of antenatal anxiety was observed among women with GDM, particularly in Asian populations, although precise prevalence estimates remain uncertain due to extreme heterogeneity. Postpartum anxiety appeared comparable to that of healthy women. Evidence regarding pre-GDM was based on only two studies and remains insufficient to draw conclusions. Findings suggest that targeted assessment and increased clinical vigilance may be appropriate in higher-risk subgroups; however, further prospective studies are needed before routine screening can be recommended.
