Yao Xin, a master’s student from the Faculty of Geographical Sciences at Beijing Normal University, has published a study in *Science Advances* examining the health risks associated with temperature variability among the elderly population in China. The research addresses the public health implications of climate change, particularly focusing on older adults.

Study Overview

The study, entitled “Elderly Vulnerability to Temperature-Related Mortality Risks in China,” was published on February 5, 2025. Its objective is to quantify the effects of temperature fluctuations on mortality rates within this demographic group. The research was conducted in collaboration with academics from Beijing Normal University, Texas A&M University, the University of Pennsylvania, Renmin University of China, and Peking University.

Methodology

To carry out this research, data from a longitudinal survey involving 27,233 elderly citizens between the years 2005 and 2018 were utilized. The study found correlations between rising temperatures, temperature variability, and increased mortality risk among the elderly. Key factors identified include the intensity of extreme heat and its prolonged duration, both of which contribute significantly to higher mortality rates.

Influencing Factors

Furthermore, the research highlights how demographic factors such as geographic location, gender, age, obesity, income, and diet influence individual vulnerabilities to temperature-related health risks.

Implications of Findings

The findings underscore the urgent need for enhanced health service systems designed to address the specific requirements of the elderly, as climate change continues to affect health outcomes. The study also suggests the potential for similar research in other countries with aging populations facing similar climate challenges.
