Obesity and the experienced cultural, economic, and climate variations among immigrants to high-income countries: An umbrella review of the literature.
Review in Public health nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveObesity is a growing global public-health concern, particularly among immigrants to high-income countries. This umbrella literature review synthesizes evidence from systematic reviews to explore the multifactorial cultural, socioeconomic and environmental determinants of obesity and weight gain among immigrants to high-income countries.
designA systematic search of PubMed, Web of Science, and Scopus was conducted from January 2015 to November 2025 to identify systematic reviews and meta-analyses examining the impact of cultural, socioeconomic, and environmental factors on obesity among adult immigrants (i.e., economic, students, and refugees) to high-income countries.
setting33 reviews were included and thematically synthesized under four domains: physical climate and physiological changes, socioeconomic stressors and psychological mediators, cultural factors, and methodological quality - rated using the AMSTAR tool.
resultsThe review found consistent evidence linking longer duration of residence and higher levels of acculturation with increased obesity risk. Socioeconomic disadvantage, food insecurity, and psychological stress-particularly acculturation stress-were key mediators of weight gain. Less sunny colder climates impacted on weight gain indirectly through limiting physical activity and accessibility to traditional-healthy diet outlets. Cultural dietary transitions and intergenerational differences further influenced obesity trajectories. Methodological quality varied, with only six reviews providing meta-analysis pooled estimates of obesity and being rated as high to moderate quality.
conclusionsObesity among immigrants is shaped by intersecting cultural, socioeconomic, environmental and physiological factors. Public-health strategies must adopt culturally sensitive approaches that address structural barriers and support healthy transitions post-migration. Future research should emphasise longitudinal, intersectional, and climate-tailored studies to inform targeted interventions.
