Prevalence of postpartum depression in the COVID-19 pandemic and associated factors: 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
backgroundThe COVID-19 pandemic created a disruptive scenario with an increase in the prevalence of postpartum depression (PPD) and new associated risk factors, which deserve to be better studied, in different global contexts, which led to the present systematic review study.
methodsObservational studies published in English, Portuguese, and Spanish between 2020 and 2025 were included, and a meta-analysis was conducted using a random-effects model.
resultsAn initial survey of 1741 articles, of which 90 studies were selected with a total of 64,6994 women evaluated for PPD, with a range between 50 (1) and 5,134 (2) women. The overall prevalence of postpartum depression during the COVID-19 pandemic was 28.48% (25.14-31.94), with rates of 23.52% (18.961-28.40) in studies that used the Edinburgh Postnatal Depression Scale (EPDS) as a diagnostic instrument with a cutoff point ≥ 13. Studies from 31 countries were included, with higher prevalence observed in Latin America (34.08%), with lower rates in Europe (31.50%), the Middle East (29.31%), USA/Canada (24.26%), and Asia (22.32%). There was a higher prevalence of PPD in countries with a lower Human Development Index (HDI) (30.95%), with higher COVID-19 CFR (32.56%), higher maternal mortality (30.43%); and with the highest Gender Inequality Index (GII) (35.41%). PPD rates increased with postpartum time, varying between 18.31% (up to 1 month), 20.78% (up to 3 months), 34.67% (up to 6 months) and 36.55% (up to 12 months). Additionally, 11 protective factors and 53 risk factors were identified, most related to the pandemic, but also with the presence of factors already consolidated in the literature before the pandemic. DISCUSSION: There was a global increase in the prevalence of PPD during the pandemic, with an intensification of pre-existing regional differences, causing the impact of the pandemic to be different according to the region.
conclusionsThe social and health crisis of the pandemic negatively impacted postpartum mental health, with significant regional differences.
