Abstract

Limited research focuses on risk perceptions of hot weather among ethnic minority groups in remote mountain areas of China. Adopting a multi-stage sampling method, this study received completed questionnaires from 643 participates in Enshi Tujia and Miao Autonomous Prefecture of China in 2017 and 2018. We used multivariate logistic regression models to explore the factors affecting risk perceptions and coping behaviors with regards to hot weather. Results showed that despite a relatively high level of risk perception, the study population in the mountain areas of China had a very low level of preparedness in responding to the risks from heat, and a lack of professional health knowledge in general. In particular, 61.3% (95% CI: 57.1%−5.6%) of the participants felt increasing temperatures in recent years, 73.2% (95% CI: 69.3%−7.0%) thought extreme high temperatures would be a health threat, and 61.3% (95% CI: 57.1%−5.4%) reported physical discomfort during hot weather. However, only 12% (95% CI: 9.5%−4.5%) had the information or knowledge to stay healthy during the extreme high temperatures, and only 24.2% had (95% CI: 20.8%−7.6%) preparation. The logistic regression models suggested that ethnic group, health status, marital status, gender, and employment could affect their perceptions, which could significantly affect the adoption of coping behaviors. In conclusion, our findings have significant implications for developing policies and health education and promotion programs for ethnic minorities in remote regions to maintain good health during hot weather.

Highlights

Global climate change is bringing more and more hot weather across the world, which has threatened human health [1,2,3]
To address the urgent need to pay more attention to the health risks associated with hot weather among ethnic minority residents, our study aimed to provide more evidence to support local policy and decision making to build community resilience
Our study has analyzed the perception of health risks from hot weather, and coping behaviors among ethnic minority residents in mountain regions of China

Summary

Introduction

Global climate change is bringing more and more hot weather across the world, which has threatened human health [1,2,3]. Panel on Climate Change (IPCC), the global surface temperature has continued to rise since 1880; the average global temperature has increased by 0.85 ◦ C in an accelerated manner [4]. In the summer of 2018, many countries in Asia, Europe, and North America experienced extreme heat events. The Chinese Meteorological Department announced that the summer of 2018 was the hottest since. One of the most important and direct impacts of climate change is the health effect from very high temperatures [4]. High temperatures could push the human body’s core temperature regulation system to an overload state, leading to injured organs and tissues that are unable to function normally
