Global Review of 53 Studies Ties Climate Exposures to Malnutrition, Infection and Cultural Disruption in Indigenous Children

The review, published in Globalization and Health, aggregated evidence from observational cohorts, cross-sectional surveys and qualitative studies spanning Arctic, Amazonian, Australian and Pacific settings. Researchers mapped six climate exposures to five health domains, with the most consistent signal appearing in psychosocial and cultural well-being metrics. Disruption of seasonal practices and land access correlated with elevated anxiety, grief and depression scores in multiple communities.

Contextual analysis reveals that existing global climate-health databases under-sample Indigenous populations; nearly half the included papers failed to stratify results by Indigenous status. This gap mirrors broader patterns in Lancet Countdown reports, where data from high-income urban centers dominate. Intersecting vulnerabilities arise because cultural continuity, rather than biomedical factors alone, mediates resilience to environmental change.

Next steps require geographically expanded longitudinal cohorts that embed Indigenous governance from design through interpretation. Without such studies, projections of attributable burden will remain imprecise and policy responses will lack cultural specificity.
