Promoting clean energy transition in rural areas is a key path to achieving global sustainable development, protecting public health, and promoting ecological livability. Based on data from the China Family Panel Studies (CFPS), this paper employs a multi-dimensional fixed effects model to evaluate the impact of income inequality on rural households’ clean energy transition (CET) and examines its underlying mechanisms. Research findings indicate that income inequality significantly suppresses rural households’ CET, primarily by reducing basic energy consumption and hindering the upgrading of basic energy consumption structures. Government governance quality exerts a significant negative moderating effect on the relationship between income inequality and rural households’ CET. Further analysis shows that the inhibitory effect of income inequality on CET is more significant in the regions with a low economic development level and low coal resource endowment, and in the western and northeastern regions of China. Therefore, while continuously promoting rural income growth, the government should prioritize equitable distribution, strengthen institutional capacity-building, improve the social service and security system, and facilitate rural households’ CET.

Plant diversity, as a critical indicator of wetland ecosystem health and functionality, has garnered extensive research attention. However, systematic and quantitative assessments of research advancements in wetland plant diversity remain inadequate. This study pioneers a global bibliometric analysis of wetland plant diversity research (1986–2025), designed to systematically examine its worldwide patterns, knowledge architecture, and evolutionary trends. Bibliometric analysis was performed using CiteSpace V6.2.R4 (64-bit) software on 482 publications retrieved from the Web of Science Core Collection. Results indicate that the United States, Canada, China, and several European countries have collectively prioritized wetland plant diversity research, forming a close international collaboration network. Research themes initially centered on species composition, community structure, and diversity metrics have expanded to multiple dimensions such as ecosystem functions and services, environmental change impacts, and wetland management and restoration, forming several key research clusters. Keyword time-zone mapping reveals the trajectory of research themes from basic descriptions to applied and environmental relevance, while emergent analyses accurately identify hotspots and frontiers of current research such as ecosystem services, functional diversity, and climate change impacts. These findings contribute to comprehending the overall framework and developmental trajectories in wetland plant diversity research, and provide a reference for identifying potential research gaps and planning future research directions.

A growing knowledge base highlights the importance of accounting for a variety of social and structural determinants of health (SDOH) when understanding mental and behavioral health among adolescents and young adults. The objective of the current study is to examine patterns of self-reported SDOH deficits and characterize participant health indicators and social identity across classes. Data is from a cross-sectional national study of young people who were recruited through study advertisements on social media and surveyed online. Data were collected between June 2022 and October 2023. Eligibility included (1) ages 13–22 years, (2) living in the United States, and (3) proficient in English. Health indicators included suicide attempts, suicidal ideation, drug overdose, perceived likelihood of living to age 35, non-suicidal self-injury, recent alcohol use, and depression. Five classes of SDOH deficits were identified: (1) Economic Instability, (2) Low Overall SDOH Deficits, (3) High Social SDOH Deficits (adversity and discrimination), (4) High Economic SDOH Deficits, and (5) High Overall SDOH Deficits. Differences across class by health indicators and marginalized identity were found, with high proportions of gender minority and sexual minority youth in both the High Overall SDOH Deficit group and the High Social SDOH Deficit classes. Black youth were more likely to be part of the High Economic SDOH Deficits class. The findings encourage a public health approach that recognizes that improving the health of today’s young people must be connected to policies that reduce poverty, improve neighborhoods, and increase access to basic goods, services, and healthcare.

This study integrates socio-demographic factors and local sustainability indicators to assess their implications for public health and social vulnerability in the Henequén neighborhood of Cartagena, Colombia. This historically marginalized community, primarily composed of women and displaced families, faces chronic exposure to environmental contaminants due to its past as a municipal landfill. Poor housing conditions, overcrowding, and inadequate access to water and sanitation services exacerbate health risks. Additionally, low educational attainment and limited economic opportunities contribute to cycles of poverty and illicit activities, disproportionately affecting children’s development. Using a cross-sectional and correlational approach, the study identifies key variables, such as housing conditions, access to basic services, and marital status, that shape social vulnerability. The findings are analyzed in the context of the United Nations Sustainable Development Goals (SDGs), particularly SDG 3 (Good Health and Well-being), SDG 6 (Clean Water and Sanitation), and SDG 11 (Sustainable Cities and Communities). The study highlights critical gaps in sustainability efforts and provides a framework for assessing local progress toward achieving these global development objectives. Full article

This study proposes and examines the dynamics of a susceptible–exposed–infectious–recovered (SEIR) model for the spread of seasonal influenza. The population is categorized into four distinct groups: susceptible (S), exposed (E), infectious (I), and recovered (R) individuals. The symmetric model integrates a bilinear incidence rate alongside a nonlinear recovery rate that depends on the quality of healthcare services. Additionally, it accounts for the impact of fear related to the disease and includes a constant vaccination rate as well as a nonlinear treatment function. The model advances current epidemiological frameworks by simultaneously accounting for these interrelated mechanisms, which are typically studied in isolation. We derive the expression for the basic reproduction number and analyze the essential stability properties of the model. Key analytical results demonstrate that the system exhibits rich dynamic behavior, including backward bifurcation (where stable endemic equilibria persist even when the basic reproduction number is less than one) and Hopf bifurcation. These phenomena emerge from the interplay between fear-induced suppression of transmission, treatment saturation, and healthcare quality. Numerical simulations using Saudi Arabian demographic and epidemiological data quantify how increased fear perception shrinks the bistability region, facilitating eradication. Healthcare capacity improvements, on the other hand, reduce the critical reproduction number threshold while treatment accessibility suppresses infection loads. The model’s practical significance lies in its ability to identify intervention points where small parameter changes yield disproportionate control benefits and evaluate trade-offs between pharmaceutical (vaccination/treatment) and non-pharmaceutical (fear-driven distancing) strategies. This work establishes a versatile framework for public health decision making and the integrated approach offers policymakers a tool to simulate combined intervention scenarios and anticipate nonlinear system responses that simpler models cannot capture.

This innovative study focuses on identifying the primary trends in citizens’ decision-making regarding sustainable and healthy water use and the promotion of tap water options. The primary objective of this study was to investigate whether there was a connection between citizen-consumer choices of tap water versus bottled water and their socio-demographic attributes or environmental awareness and consciousness, which both influence the access to and quality of drinking water. The availability, safety and quality of drinking water is a basic human right and an important public health issue. Water plays a crucial role in terms of increasing geo-political and socio-economic importance. Several researchers have examined the multiple elements influencing customers’ opinions about the quality of water and services, finding that a variety of internal and external factors play a role. To accomplish the study goals, a variety of research methodologies were applied to the use case of Kilkis city, Region of Central Macedonia, Greece. Gaining insight was first facilitated via communication with a focus group of local professionals and policy-makers. Then, a social survey of 407 randomly chosen citizens was conducted to collect the data. The key determinants influencing citizens’ drinking water choices were investigated using multivariate data analysis. Specifically, cluster analysis was employed to group customers exhibiting similar water usage patterns, resulting in the identification of two groups: (a) individuals who favored bottled water and (b) individuals who favored tap water with no filtration. The comparison of the distribution of water consumers between these two clusters, via a Chi-Square test with cross tabulation analysis, showed that customers’ drinking water buying habits were not influenced by their socio-demographic traits. On the other hand, the choice of tap water was found to be positively connected to citizens’ increased level of environmental consciousness. The outcomes of this study can help the stakeholders involved to assist in making improvements to customer service programs for encouraging tap water use, as a more sustainable and healthy water option. Moreover, the population could potentially be motivated to adopt updated technologies for recycling water down the line, moving towards sustainable water resource management. Full article

Background: Basic healthcare may significantly decrease neonatal morbidity and mortality. Attention to this, particularly in populations where rates of potentially preventable illness and death within the first weeks of life are extremely high, will have a positive impact on global health. Objective: This manuscript presents the development and impact of a quality improvement programme to reduce the evidence–practice gap in care for neonates admitted to the NICU in a public hospital in India. The programme was locally customised for optimal and sustainable results. Method: The backbone of the project was educational exchange of neonatal nurses and physicians between Norway and India. Areas of potential improvement in the care for the neonates were mainly identified by the clinicians and focus areas were subject to dynamic changes over time. In addition, a service centre for lactation counselling and milk banking was established. Progress over the timeframe 2017–2019 was compared with baseline data. Results: The project has shown that after a collaborative effort, there is a significant reduction in mortality from 11% in the year 2016 to 5.5% in the year 2019. The morbidity was reduced, as illustrated by the decrease in the proportion of neonates with culture-proven sepsis. Nutrition improved with consumption of human milk by the NICU-admitted neonates remarkably increasing from one third to more than three forth of their total intake, and weight gain in a subgroup was shown to increase. With the introduction of family participatory care, hours of skin-to-skin contact for the neonates significantly increased. Additional indicators of improved care were also observed. Conclusions: It is feasible to reduce neonatal mortality and morbidity in a low- and middle-income hospitalised population by improving basic care including nutrition relatively inexpensively when utilising human resources.

This study presents new empirical findings on the multidimensional barriers that disadvantaged communities must overcome to equitably access quality education and health services. Equitable access to education and health services in disadvantaged communities requires comprehensive public policies that address multidimensional barriers. Through an innovative econometric analysis of primary data collected in 50 rural communities, the most influential factors hindering access to these basic services are identified. This article discusses the most effective public policy strategies for improving access to and the quality of education and health services in disadvantaged communities, and outlines how to implement them sustainably and equitably. The results reveal that a lack of adequate infrastructure, a shortage of qualified personnel, and socioeconomic and cultural barriers are the main obstacles. Based on these findings, a new comprehensive intervention model is proposed, which simultaneously addresses these interconnected barriers. These strategies contribute directly to the Sustainable Development Goals (SDGs), particularly SDG 3 (Good Health and Well-being) and SDG 4 (Quality Education), by addressing critical barriers to equitable access to essential health and education services in marginalized communities. These strategies are based on theories that highlight the importance of investing in education and health for human and economic development, and support the fact that investments in these sectors boost productivity, income, well-being, and equity. The study concludes with practical and applicable recommendations for public policymakers, emphasizing the importance of adapting them to the local context and ensuring the active participation of the beneficiary communities.

Brazilian garimpeiros are a highly hard-to-reach and mobile population, with little access to basic hygiene and health services, and have been crossing the border to work irregularly in gold mines in French Guiana since the 1990s. This study aimed to characterize this population and identify their main health problems. A cross-sectional study was carried out in the municipality of Oiapoque-AP, with two surveys: before (2018) and after (2019) the implementation of Malakit. Individuals were recruited from resting places and given a questionnaire regarding demographic variables, history and knowledge of malaria, and health issues in the mines. Simultaneously, a clinical evaluation was performed. The garimpeiros were mainly men from Maranhão, Pará, and Amapá, with a low educational level and who had worked on average for 10 years in the mining sites. The study population mentioned numerous health problems: malaria, followed by leishmaniasis, flu, body aches, headaches, and digestive problems. Other diseases mentioned were skin diseases, bat bites, hepatitis, and HIV infection. This vulnerable population is constantly subjected to heavy routines and exposed to different diseases and infections that can spread across borders. Knowledge of this is essential for developing public health policies that can be integrated into specific epidemiological situations. Full article

Access to safe drinking water is a fundamental human need for health and well-being implemented globally by the United Nations under Sustainable Development Goal (SDG) 6. Storing drinking water is common in rural areas of Ethiopia due to off-premises water sources and intermittent piped water supply. However, this practice can lead to further contamination during collection, transport, and storage, posing a risk to public health. The objective of this study was to identify the determinant factors of drinking water quality at the point of use in the rural setting of northwestern Ethiopia, South Gondar zone. A questionnaire survey was conducted, and water samples from 720 households were collected during the wet and dry seasons. The determinant factors were identified using the multivariable logistic regression model. About 39.2% of the surveyed households had basic water supply services, 41.9% were using unimproved sources, and 8.3% were using surface water. Only 9.4% were using basic sanitation services, and 57.2% were practicing open defecation. Safe water storage was practiced by 84.3% of households, while only 2% engaged in household water treatment. About 14% of dry and 8% of wet season samples from the storage were free from fecal coliform bacteria. Furthermore, 52.9% of dry and 62.2% of wet season samples fell under the high microbial health risk category. The season of the year, the water source type, storage washing methods, and the socioeconomic status of the household were identified as key predictors of household drinking water fecal contamination using the multivariable logistic regression model. It was observed that the drinking water in households had a high load of fecal contamination, posing health risks to consumers. To tackle these problems, our study recommends that stakeholders should enhance access to improved water sources, implement source-level water treatment, increase access to improved sanitation facilities, advocate for safe household water management practices, and endorse household water treatment methods.

In Africa, the urban population and informal settlements are increasing, resulting in additional public health and environmental risks and challenges related to the need for basic and sustainable infrastructures and services. In Maputo, the capital of Mozambique, at least 80% of the city is composed of informal settlements, and although some areas are regularized and have approved urbanization plans, the municipality has major deficiencies in meeting current demands in terms of basic infrastructures, such as water supply, sewerage, solid wastes, energy, roads, and communications. Most of the peri-urban areas are occupied by small but overcrowded houses, mostly self-built, served by unpaved roads, and with access limitations. The water pipe network is almost non-existent, and the same occurs with stormwater drainage, sanitation, waste collection, and public illumination services. Despite the improvements made in the last few years, some households still do not have safe sanitation, and in some neighborhoods, open defecation still prevails. In this study, the authors try to understand and explore the interdependences among the infrastructures of the different sectors and how they may jointly contribute to adequate services and a better life for the urban poor. And how to identify the combination of infrastructures to be implemented in the short term in the face of limited budgets for investments. For that purpose, a simplified conceptual approach is proposed and applied to an informal neighborhood in Maputo. Full article

As an integral part of the urban public health infrastructure, public toilets play a significant role in shaping a city’s image. With the advancement of the economy, people have increasingly higher expectations for public toilets. While existing standards primarily focus on physical indicators, there is still room to incorporate measures that prioritize humanistic care. Therefore, based on the Human Rights to Water and Sanitation in Public Spaces (HRWS-PS) standards, this study develops a comprehensive index system for public toilets with a specific emphasis on humanistic care, utilizing expert questionnaires and employing methods such as the analytic hierarchy process (AHP) and entropy weight, and highlights safety and quality as paramount concerns for users, followed by usability and accessibility as secondary needs. Acceptability, which encompasses additional amenities, depends on meeting these secondary needs through solid basic design and construction practices. Affordability, related to consumer costs, is comparatively less demanding. By applying this framework, an analysis of the current state of upgrading urban public toilets in Shijiazhuang was conducted, leading to recommendations for improvements across four key areas: environmental sanitation, architectural design, infrastructure development, and urban planning. The final results provide practical insights for evaluating and suggesting enhancements to ongoing toilet revolution initiatives and urban basic service facilities while also informing urban renewal efforts and designs.

The inequalities of Brazilian society are amplified in favelas, affecting access to basic sanitation, health, education services, and food. More research is needed to better understand the favela food environment and propose appropriate public food and nutrition policies to increase the availability of and access to healthy food. In this context, this study aimed to develop a conceptual model of the relationship between access to food and the favela food environment and its determinants. In developing the conceptual model, this study undertook a bibliographical survey of the food environment, and a preliminary version was submitted to an expert panel. The model represents a set of dimensions (individual, micro-environment, macro-environment, and decision-making) and elements that interact in a complex manner and help understand access to food in areas subject to multiple social vulnerabilities. This model can guide future research and aid policymakers in designing effective strategies to improve the food security and health of populations in areas of high socio-spatial vulnerability.

The present work examines the relationship between aerial spraying and its health impacts on the population living in the banana production areas of Ecuador (the rural sectors of the cantons Milagro and Naranjito, Guayas Province). Objectives: the objectives of this study are to obtain information on sanitation, basic services, and environmental rationality and to interpret the low levels of cholinesterase and prevalent diseases among the population. Methods: the methodology involved a face-to-face questionnaire, the formal authorization of an informed consent document, and venipuncture for cholinesterase tests. The information was processed in the EPI–INFO system 7.2 (statistical software for professionals and researchers dedicated to public health), with the certification of protocols issued by the Bioethics Committee of the Kennedy Hospital Clinic of Ecuador. Results: the results showed that 89.5% of inhabitants do not have access to drinking water, 92.5% do not have a sewage disposal service, 97.50% experience aerial spraying at their homes or workplaces, and 57% have low cholinesterase levels. Additionally, several gastrointestinal, respiratory, neurological, dermatological, and reproductive disorders were detected among the inhabitants. Conclusions: we found that companies in the banana sector have not implemented corporate social responsibility measures. For example, no blood tests are conducted to monitor cholinesterase levels or to track hereditary disorders. Moreover, entities such as the Ministry of Public Health have not taken action to serve this at-risk population. Full article

Background and Objective: Limited access to health services and low educational levels are factors in the rural population that are associated with the development of oral pathologies. However, the specific risk indicators contributing to erosive tooth wear (ETW) in these populations remain unclear. The objective of this study was to identify risk indicators associated with the prevalence of erosive tooth wear (ETW) in schoolchildren aged 8–12 years from rural and urban areas in the State of Mexico. Methods: A cross-sectional study was carried out in public schools in rural and urban areas. The prevalence of ETW was evaluated using the Basic Erosive Wear Examination (BEWE). The risk indicators studied were gastroesophageal reflux, vomiting, vitamin C, food, beverages, dental hygiene, bruxism, and hyposalivation. Logistic regression models were used to calculate odds ratios (OR) and 95% confidence intervals (CI). Results: The prevalence of ETW was higher in the rural area (77.3%) compared to the urban area (51.2%) (p = 0.001). The odds of presenting ETW were more than twice in schoolchildren from rural areas compared to those from urban areas (OR: 2.25, 95% CI: 1.11–3.98). Risk indicators varied between rural and urban populations, with different factors such as the consumption of fresh tomato sauce, orange, tangerine, atole (artisanal corn-based drink), and teeth grinding in the rural area, and lemon, soft drink, fruit juice consumption, and the simplified oral hygiene index in the urban area (p < 0.05). Conclusions: To prevent ETW, strategies offering tailored dietary and hygiene advice should be proposed, considering the specific conditions of each geographic area. Full article
