Global systematic review of how climate change degrades the wellbeing and health of Indigenous children.
Synthesis in Globalization and health, 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
backgroundClimate change worsens global health, with Indigenous children among the most vulnerable. Despite increasing research on climate-related health impacts, Indigenous children's unique vulnerabilities remain underrepresented. This is the first review to synthesise systematically the global evidence on how climate change impacts the health of Indigenous children.
methodsWe consolidated reported health outcomes directly caused by climate change in Indigenous children. We adhered to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and followed a reflexive framework that considered researcher positionality, Indigenous definitions of health, and ongoing Indigenous engagement. We did a systematic search of five databases on 2 March 2025 and collaboratively screened eligible studies on climate-related health outcomes in Indigenous children and pregnant women, assessing them using the mixed-methods appraisal tool. A convergent integrated synthesis approach mapped exposure-outcome patterns and guided a theme-based narrative analysis. Meta-analysis was not feasible due to study heterogeneity.
resultsFifty-three studies met inclusion criteria, comprising 16 qualitative, 23 quantitative non-randomised, 6 quantitative descriptive and 8 mixed-method designs. Five main health outcomes emerged: (i) psychosocial and cultural wellbeing, (ii) malnutrition, (iii) infectious diseases, (iv) perinatal health, and (v) morbidity and mortality. Reflecting the interconnected and relational nature of Indigenous health conceptualisations, most studies addressed multiple climate exposures and outcomes. Psychosocial and cultural wellbeing was the most cross-cutting theme, interconnected with all other health domains. Heat exposure and seasonal and hydroclimatic variability were the most frequently linked climate exposures.
conclusionsIndigenous children across diverse contexts are experiencing adverse climate-related health outcomes. Our review consolidates the evidence base to inform culturally grounded, strengths-based responses that engage Indigenous Knowledge systems and younger generations. Advancing this field requires more geographically diverse, disaggregated, and methodologically rigorous research.
