A Survey of Rural Residents' Perception and Response to Health Risks from Hot Weather in Ethnic Minority Areas in Southwest China

A scoping review of the impact of extreme weather events on health outcomes and healthcare utilization in rural and remote areas

BACKGROUND

Extreme weather events affect health by directly and indirectly increasing illness burdens and changing healthcare usage patterns. These effects can be especially severe in rural and remote areas, exacerbating existing health disparities, and necessitating urgent mitigation or adaptation strategies. Despite increased research on health and climate change, studies focusing on rural and remote populations remain limited. This study aimed to review the relationships among extreme weather events, healthcare utilization, and health outcomes in rural and remote populations, identify research gaps, and inform policy development for adaptation and disaster management in these settings.

METHODS

A systematic scoping review was registered and conducted following the PRISMA-ScR guidelines. The search databases included PubMed, Web of Science, Scopus, the Cochrane Library, ProQuest, and the WHO IRIS. The included studies were primary research, focused on rural or remote areas, and investigated the effects of extreme weather events on either health outcomes or healthcare utilization. There were no methodological, date or language restrictions. We excluded protocols, reviews, letters, editorials, and commentaries. Two reviewers screened and extracted all data, other reviewers were invited to resolve conflicts. Findings are presented numerically or narratively as appropriate.

RESULTS

The review included 135 studies from 31 countries, with most from high-income countries. Extreme weather events exacerbate communicable and noncommunicable diseases, including cardiorespiratory, mental health, and malnutrition, and lead to secondary impacts such as mass migration and increased poverty. Healthcare utilization patterns changed during these events, with increased demand for emergency services but reduced access to routine care due to disrupted services and financial constraints.

CONCLUSIONS

The results highlighted the essential role of community and social support in rural and remote areas during extreme weather events and the importance of primary healthcare services in disaster management. Future research should focus on developing and implementing effective mitigation and adaptation programs tailored to the unique challenges faced by these populations.

The practices of heat adaptation among elderly in Dezful: A qualitative study

BACKGROUND

Useful experiences of the elderly in adapting to the environment may play an important role in formulating future policies. This study was conducted to explain the past experiences of the elderly in Dezful in adapting to heat.

MATERIALS AND METHODS

This study was conducted with a qualitative research approach and a qualitative content analysis method in 2020 and 2021. The experiences of 18 elderly in Dezful were collected through semi-structured interviews via recording, face-to-face interviews, and data observation. Sampling was performed by the purpose-based method, and the data of this stage were analyzed using a content analysis approach using the Zhang and Wildemuth method.

RESULTS

During the data analysis process, three main themes were extracted, including psychophysiological, socioeconomic, and environmental adaptation. Also, twelve subthemes including changes in physiological conditions, urban architecture, house architecture, diet, clothing, business conditions, mindset, life conditions, and the use of factors (spirituality, experience, and natural capacities) were extracted.

CONCLUSION

Explaining the experiences of the elderly in Dezful, who have lived with heat for many years, can provide better identification of solutions and more tangible experiences of adaptation to heat for other communities. These experiences can be used in urban, cultural, and social planning.

Effects of climate-related risks and extreme events on health outcomes and health utilization of primary care in rural and remote areas: a scoping review

BACKGROUND

Rural populations are at risk of climate-related impacts due to ecological and geographical determinants, potentially leading to greater morbidity and health utilization. They are often highly dependent on primary care services. However, no rural- or primary care specific synthesis of these issues has ever been conducted. This review aimed to identify, characterize, and summarize existing research on the effects of climate-related events on utilization and health outcomes of primary care in rural and remote areas and identify related adaptation strategies used in primary care to climate-related events.

METHODS

A scoping review following PRISMA-ScR guidelines was conducted, examining peer-reviewed English-language articles published up to 31 October 2022. Eligible papers were empirical studies conducted in primary care settings that involved climate-related events as exposures, and health outcomes or utilization as study outcomes. Two reviewers independently screened and extracted relevant information from selected papers. Data were analysed using content analysis and presented using a narrative approach.

RESULTS

We screened 693 non-duplicate papers, of those, 60 papers were analysed. Climate-related events were categorized by type, with outcomes described in terms of primary, secondary, and tertiary effects. Disruption of primary care often resulted from shortages in health resources. Primary care may be ill-prepared for climate-related events but has an important role in supporting the development of community.

CONCLUSIONS

Findings suggest various effects of climate-related events on primary care utilization and health outcomes in rural and remote areas. There is a need to prepare rural and remote primary care service before and after climate-related events.

Does Ethnic Diversity Impact on Risk Perceptions, Preparedness, and Management of Heat Waves?

Detrimental health impacts of heatwaves, including excess mortality, are increasing worldwide. To assess risk perceptions, protective knowledge and behaviors concerning heatwaves in Israel, a study was initiated, comparing attitudes of majority (Jewish) and minority (Arab) populations. A quantitative survey was disseminated through an internet panel, to a representative sample of 556 individuals (79% Jews; 21% Arabs). Overall, 74% consider heatwaves a problem, 93% believe that heatwaves' frequencies will increase, 27% are very concerned about the effects of heatwaves. Higher levels of awareness to heatwaves were found among Jewish compared to Arab respondents; 90 vs. 77% (respectively) could name heatwaves' symptoms (p < 0.001); 81 vs. 56% (respectively) reported knowing how to protect themselves (p < 0.001); 74 vs. 47% (respectively) reported knowing what to do when someone suffers from heat stroke (p < 0.001). Arab compared to Jewish respondents presented higher levels of concern about heatwaves' effects (3.22 vs. 3.09 respectively; t −2.25, p = 0.03), while knowledge of protective measures was higher among Jews compared to Arabs (3.67 vs. 3.56 t = 2.13 p = 0.04). A crucial component of enhancing preparedness to heatwaves is empowerment of minority as well as majority groups, to strengthen their capacity to implement protective behavior and elevate their self-belief in their individual ability and fortitude.

Dietary Behaviours Among Han, Tujia and Miao Primary School Students: A Cross-Sectional Survey in Chongqing, China

Background and Purpose

Exploring the differences of children's dietary behaviours from different nationalities could provide a reference for targeted nutritional interventions. This study aims to assess the dietary behaviours among Han, Tujia and Miao primary school students and the differences among the ethnic groups.

Materials and Methods

This cross-sectional survey included 556 primary school students (249 Han, 76 Tujia and 231 Miao students) aged 6-13 years from the representative minority areas of Chongqing, China. Data were collected with a self-administered or one-on-one interview-based questionnaire encompassing questions on sociodemographics, eating habits and dietary intake. Eating habits and dietary intake were categorized into health-protective and health-risk dietary behaviours. χ² tests were conducted to examine the differences in eating habits and dietary intake among the three ethnic groups. Forward stepwise logistic regression models were performed to check the factors affecting dietary intake.

Results

Fewer than half of the students had health-protective dietary behaviours in terms of rice, fruit, fish, eggs and milk intake. Compared with Han students, Tujia students were more likely to meet the recommended intake of vegetables (OR = 2.13, 95% CI [1.22-3.69]), less likely to meet the recommended intake of meat (OR = 0.58, 95% CI [0.35-0.94]) and fish (OR = 0.55, 95% CI [0.32-0.94]); Miao students were more likely to meet the recommended intake of vegetables (OR = 1.73, 95% CI [1.20-2.51]), fruits (OR = 1.62, 95% CI [1.16-2.28]) and water (OR = 1.59, 95% CI [1.12-2.26]) than those of Han students.

Conclusion

The low proportion of health-protective dietary behaviours among primary school students from Han, Tujia and Miao ethnicities was found in this study. There were differences in dietary behaviours among the three ethnic groups. This study could provide a reference for implementing national dietary guidelines in consideration of socioeconomic status, ways of preparing and consuming foods, traditional foods and customs of different ethnic groups.

Predictors Associated with Health-Related Heat Risk Perception of Urban Citizens in Germany

The rising probability of extremely high temperatures and an increasing number of consecutive hot days caused by climate change-combined with the impact of these high temperatures on human health-is widely discussed in the literature. There are calls for the development of heatwave adaptation measures by governmental and scientific institutions. In this research, the predictors of health-related heat risk perception of urban citizens in Augsburg, Germany, were investigated. An online survey was conducted with 468 citizens, asking about their heat risk perception, knowledge about heat risks, and demographic data and health information. Statistical methods (Spearman correlation, unpaired t-test, ANOVA and multiple regression) were used to determine which factors were significant and relevant. The results show that the knowledge of heat risks, heat risk sensitivity and an external locus of control are the most important factors for heat risk perception. The health implication score and chronic disease show significant effects in descriptive statistics. Furthermore, younger people showed the highest heat risk perception of all age groups. Surprisingly, income, education, living alone and gender did not play a role in heat risk perception. The findings imply a need for better and intensified heat risk communication in urban areas-especially among elderly people-and thus are important for creating acceptance towards heat wave risks, which is a prerequisite of willingness to adapt.

Residents' Diachronic Perception of the Impacts of Ecological Resettlement in a World Heritage Site

As one of the main factors in any tourist destination, residents' perception of the impacts of ecological resettlement has a substantial influence on the sustainable development of any world heritage site. Our research takes the residents of three different resettlement locations in the Wulingyuan scenic area, a world heritage site, as the object of our survey. Based on questionnaire investigations in 2010 and 2016, this article analyzes the residents' diachronic perception of the impacts of ecological resettlement. Independent sample t-tests and Analysis of Variance (ANOVA) are used to compare the differences in residents' perception toward ecological relocation and analyse how demographic characteristics affect residents' perception. Multiple stepwise regression analysis is applied to explore the main factors that contribute to the differences in the perception of impacts of ecological resettlement. The results show that during the study period, respondents have the strongest perceptions of the economic, socio-cultural, resource-environment and psychological impacts. However, they have negative perceptions of relocation policy impacts. Compared with 2010, residents with different gender, age, education level, income level and engagement in tourism have significant differences in perception of impacts of resettlement in 2016. Multiple stepwise regression analysis demonstrates that the perceptions of impacts of the ecological resettlement and economic policy are the primary factors to affect residents' overall perceptions.
