Current status and time trends in the burden of environmental heat and cold exposure among the population aged 60 years and older: an analysis for the Global Burden of Disease Study 2021.
Article in BMC public health, 2025. 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
backgroundClimate change significantly challenges public health, particularly through extreme weather events that disproportionately affect older adults. Those aged 60 and older are especially vulnerable to environmental heat and cold exposure (EHCE) due to physiological and healthcare access challenges. This study aims to analyze EHCE-related prevalence, incidence, mortality, and disability-adjusted life-years (DALYs) using the Global Burden of Disease (GBD) 2021 database.
methodsWe analyzed data from the GBD 2021 to estimate global, regional, and national EHCE-related metrics for adults aged 60 and older, including age-standardized prevalence (ASPR), incidence (ASIR), mortality (ASMR), and DALY rates (ASDR). Temporal trends from 1990 to 2021 were assessed using joinpoint regression and annual average percentage changes (AAPCs). Projections for 2022-2030 were developed using a Bayesian age-period-cohort (BAPC) model.
resultsIn 2021, there were 4.4 million global EHCE cases (ASPR: 413.2 per 100,000; 95% UI: 362.4-475.6), with 301.2 thousand incident cases (ASIR: 28.2 per 100,000; 95% UI: 18.9-41), 19,078 deaths (ASMR: 1.8 per 100,000; 95% UI: 1.1-2.3), and 507.4 thousand DALYs (ASDR: 47.2 per 100,000; 95% UI: 34.4-57.5). High-SDI countries exhibited the highest prevalence (ASPR: 707.4), while low-SDI countries had the highest mortality (ASMR: 3.0). Regionally, Eastern Europe reported the highest burden, whereas Southeast Asia showed the lowest. Nationally, Greenland had the highest prevalence (ASPR: 2221.2), while Mauritius had the lowest (ASPR: 75.4). From 1990 to 2021, significant global declines were observed in ASPR (AAPC: -1.33), ASIR (AAPC: -1.47), and ASMR (AAPC: -0.83). However, reductions varied across SDI regions, with middle-SDI countries showing the largest decreases in ASPR (AAPC: -2.31) and ASIR (AAPC:-2.14). The largest regional reductions in ASPR occurred in East Asia (AAPC: -1.91) and Eastern Europe (AAPC: -1.65), while Western Europe experienced a slight increase (AAPC: 0.10). Nationally, Albania exhibited the steepest decline in ASPR (AAPC: -3.68), whereas France recorded the largest increase (AAPC: 2.55). Projections suggest continued global declines in all metrics through 2030.
conclusionsThe global burden of EHCE among the elderly remains substantial; however, it has exhibited a slight yet significant decline over the past three decades, with variations across different regions and sociodemographic profiles. These findings underscore the importance of targeted public health strategies to mitigate the impact of extreme temperatures on vulnerable older populations. By providing comprehensive data and trend analyses, this research informs climate resilience policies and adaptive interventions to address the growing challenges posed by climate change.
