Climate change and mental health burden among caregivers in California.
Article in The Gerontologist, 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
BACKGROUND AND
objectivesClimate change poses a growing threat to mental health, particularly for populations already facing chronic stress. Caregivers manage multiple responsibilities under challenging conditions, yet their vulnerability to climate-related mental health impacts remains underexplored. This study assesses whether caregivers report greater climate-related mental health burden and whether structural factors are associated with this burden. RESEARCH DESIGN AND
methodsWe conducted a cross-sectional analysis using 2023 California Health Interview Survey data. Multivariable logistic regressions assessed associations between caregiver status, structural factors, and climate-related mental health burden. Subgroup analysis among caregivers evaluated whether these associations were more pronounced in this population.
resultsCaregivers had increased odds of climate-related mental health burden (adjusted odds ratio [aOR] = 1.57, 95% CI 1.36-1.80). Within the caregiver subgroup, higher odds were associated with housing insecurity (aOR = 1.43, 95% CI 1.11-1.84), caregiving-related financial stress (aOR = 1.54, 95% CI 1.19-2.01), bisexual/pansexual identity, (aOR = 2.96, 95% CI: 2.02-4.33), and providing care to older adults (aOR = 1.31, 95% CI 1.03-1.65). Rural caregivers in neighborhoods with low community cohesion also had elevated odds (aOR = 2.65, 95% CI 1.46-4.81). DISCUSSION AND IMPLICATIONS: Caregivers reported greater climate-related mental health burden than non-caregivers. Findings highlight the role of structural factors in shaping mental health and the need for climate resilience strategies that meaningfully incorporate caregiving considerations into adaptation planning. Attending to these structural determinants is essential for building resilient responses to climate change that recognize and meet the shared needs of caregivers and their care recipients.
