Trend analysis reveals changing incidence and prevalence of environmental heat and cold exposure in adults, indicating varying impacts across regions.
Objective To analyze temporal trends of environmental heat and cold exposure (EHCE)-related burden among adults aged 55 years and older. Methods Using the Global Burden of Disease database, we examined EHCE-related incidence, prevalence, mortality, and DALYs trends from 1990–2021 via joinpoint regression, assessing global, regional, and national patterns by sex, age, and sociodemographic index (SDI). Results Global EHCE incidence declined (AAPC, -1.46), more in males (AAPC, -1.62) than females (AAPC, -1.23), notably in ages 55–59 (AAPC, -1.77). High-middle-SDI nations had the largest incidence drop (AAPC, -2.29), but mortality (AAPC, 1.07) and DALYs (AAPC, 0.38) rose in high-SDI countries. High-income Asia Pacific showed increased incidence (AAPC, 0.96). Conclusion Global EHCE burden decreased, but high-income regions showed stagnation or reversal, urging revised response strategies.
