Assessing the construction of a Healthy City in China: a conceptual framework and evaluation index system.

OBJECTIVES: COVID-19 has brought challenges to the health of all mankind. It is particularly important to promote the construction of a 'Healthy China' and build a 'healthy community'. The aims of this study were to construct a reasonable conceptual framework for the Healthy City concept and to assess Healthy City construction in China. STUDY DESIGN: This study combined qualitative and quantitative research. METHODS: This study proposes the concept model of 'nature-human body-Healthy City' and accordingly constructs an evaluation index system for the construction of a Healthy City that integrates five dimensions, namely, the medical level, economic basis, cultural development, social services, and ecological environment to explore the spatial and temporal heterogeneity of Healthy City construction in China. Finally, the influencing factors of Healthy City construction patterns are explored using GeoDetector. RESULTS: (1) The pace of Healthy City construction is generally on the rise; (2) the construction of Healthy Cities exhibits significant global spatial autocorrelation and gradually increasing agglomeration. The spatial distribution of cold hotspot areas was relatively stable; (3) medical and health progress is an important factor; the level of economic development is the leading support; the endowment of resources and environment is the basic condition; public service support provides important support; and scientific and technological innovation capabilities provide technical support for the construction of a Healthy City. CONCLUSIONS: The spatial heterogeneity of Healthy City construction in China is evident, and the state of spatial distribution is relatively stable. The spatial pattern of Healthy City construction is shaped by a combination of factors. Our research will provide a scientific basis for promoting the construction of Healthy Cities and helping to implement the Health China Strategy.

Healthy City Community Space-Oriented Structural Planning and Management Optimization under COVID-19.

This work studies ways of Healthy City Construction (HCC) and Urban Governance Optimization (UGO) during the COVID-19 pandemic. The specific urban community space planning structure is proposed following a literature review on the healthy city's theoretical basis and historical development. Then, the proposed HCC-oriented community space structure is tested by surveying residents' physical and mental health and infectious risk using a questionnaire survey and Particle Swarm Optimization (PSO). Specifically, the particle fitness is calculated according to the original data conditions, and the community space with the highest fitness is determined. Based on the calculation, the community space's neighbors are investigated from different aspects through a questionnaire survey on patients' daily activities and community health security coverage. The results showed that: (1) The score of daily activities of community patients with respiratory diseases was 2312 before the implementation of the proposed community structure and 2715 after the implementation. Therefore, the service quality of residents increases after implementation. (2) The proposed HCC-oriented community space structure improves the physical self-control ability of chronic patients and helps them reduce their pain. This work aims to create a people-oriented healthy city community space, improve the city's "immune system," and regenerate the energy and environmental sustainability of the urban living environment.

Identifying Challenges, Enabling Practices, and Reviewing Existing Policies Regarding Digital Equity and Digital Divide Toward Smart and Healthy Cities: Protocol for an Integrative Review.

BACKGROUND: Digital equity denotes that all individuals and communities have equitable access to the information technology required to participate in digital life and can fully capitalize on this technology for their individual and community gain and benefits. Recent research highlighted that COVID-19 heightened the existing structural inequities and further exacerbated the technology-related social divide, especially for racialized communities, including new immigrants, refugees, and ethnic minorities. The intersection of challenges associated with racial identity (eg, racial discrimination and cultural differences), socioeconomic marginalization, and age- and gender-related barriers affects their access to health and social services, education, economic activity, and social life owing to digital inequity. OBJECTIVE: Our aim is to understand the current state of knowledge on digital equity and the digital divide (which is often considered a complex social-political challenge) among racialized communities in urban cities of high-income countries and how they impact the social interactions, economic activities, and mental well-being of racialized city dwellers. METHODS: We will conduct an integrative review adapting the Whittemore and Knafl methodology to summarize past empirical or theoretical literature describing digital equity issues pertaining to urban racialized communities. The context will be limited to studies on multicultural cities in high-income countries (eg, Calgary, Alberta) in the last 10 years. We will use a comprehensive search of 8 major databases across multiple disciplines and gray literature (eg, Google Scholar), using appropriate search terms related to digital "in/equity" and "divide." A 2-stage screening will be conducted, including single citation tracking and a hand search of reference lists. Results will be synthesized using thematic analysis guidelines. RESULTS: As of August 25, 2022, we have completed a systematic search of 8 major academic databases from multiple disciplines, gray literature, and citation or hand searching. After duplicate removal, we identified 8647 articles from all sources. Two independent reviewers are expected to complete the 2-step screening (title, abstract, and full-text screening) using Covidence followed by data extraction and analysis in 4 months (by December 2022). Data will be extracted regarding digital equity-related initiatives, programs, activities, research findings, issues, barriers, policies, recommendations, etc. Thematic analysis will reveal how barriers and facilitators of digital equity affect or benefit racialized population groups and what social, material, and systemic issues need to be addressed to establish digital equity for racialized communities in the context of a multicultural city. CONCLUSIONS: This project will inform public policy about digital inequity alongside conventional systemic inequities (eg, education and income levels); promote digital equity by exploring and examining the pattern, extent, and determinants and barriers of digital inequity across sociodemographic variables and groups; and analyze its interconnectedness with spatial dimensions and variations of the urban sphere (geographic differences).

Learning from COVID-19-Analysis of Housing and Urban Design Influence on Users

COVID-19 pandemic, in addition to putting severe pressure on the health and economic systems, has caused considerable changes in people's lives. The influence of the environment on the psycho-social and physical state of people is an established fact in scientific research and literature but the pandemic, with its related, necessary restrictions, brought to the fore some topics that are already well-known in areas such as environmental psychology and sociology. The paper aims to analyse researches that have shown a correlation between the lived environment, private or public, well-being and mental health, with particular reference to the domestic environment. The uncertainty and the feeling of not having control over one's own life and actions can be sharpened or mitigated by the environment in which one carries out their daily activities. There is evidence that the environment is an important determinant of health and, in particular at a time of strong emotional and psychological stress such as a lockdown, significant correlations have been found between the environment and states of stress. Design strategies can therefore positively influence the relationship between man and environment. The pandemic period has led to "borderline scenarios" not only in hospitals but also, for example, in public spaces or at home, which has become a place where numerous activities are carried out, sometimes simultaneously: sleeping, eating, working, socializing, doing sports, etc. Parks, gardens, tree-lined streets have become the favourite spaces to have a short break from the house routine. It has been demonstrated that nature, in this period, is an essential factor from a restorative point of view and for the mental balance. This extreme situation must be used to develop design strategies that best meet the new needs of everyday life. Such needs, even when the infectious risk is over, will definitely be changed compared to before.

Assessment of the proximity to the Urban Green Zones of the city of Zaragoza as a strategy for adaptation to pandemic situations

The COVID-19 pandemic has generated a change in the urban paradigm, leaving evidence of the need to plan and redesign cities under the concepts of "caring city" and "healthy city", in order to adapt and make them resilient to the new post pandemic reality. To support this idea, this document studies -by means of a questionnaire- the assessment that the citizens of the city of Zaragoza make of their urban green areas before, during and after confinement, as key public spaces for the development of urban life and support in the planning processes of the "healthy city" by allowing the maintenance of the minimum social distance of safety and promoting the health and physical and mental well-being of the population. © 2022 Ciudades.

Walkable Environment: Building resilient and healthy cities post-pandemic

This paper explores the urban population's walking behaviour and mobility pattern within a walkable environment in response to the COVID-19 pandemic in the selected neighbourhood in Klang Valley, Malaysia. Data was collected through an online questionnaire survey. The key findings revealed that the pandemic limits pedestrian movement and changes their travelling methods due to the Malaysian government's Movement Control Order (MCO). As a result, walking and public transportation usage have declined due to the fear of proximity in public areas. Hence, further recommendations are required to ensure walking sustainability for daily routines whilst promoting resilient and healthy cities.

[The municipal planning for the benefit of health].

The article, on the basis of analysis of scientific publications, presents brief overview of principles and technologies of development of cities considering impact on population health. The particular attention is paid to analysis of being built areas and careful use of available resources. The definition of the term "sustainable development of territory" and description of necessary measures for its application in practice are given. The actual trend of "coronavirus" transformation of architectural urban environment is presented, including availability for each family member of one's own space, room, house and flat with terrace, balcony, separate entrances (in case when apartment is located on the first floor), expanded house territory, life outside the city. At that, reduction of social relationships is established. To control effectiveness of city management corresponding indices are presented.

Very high-resolution remote sensing-based mapping of urban residential districts to help combat COVID-19.

Urban residential districts (URDs) are a major element in the formation of cities that are essential for urban planning. Regarding the COVID-19 virus, which remains variable in aerosols for several hours, airborne transmission tends to occur in areas of poor ventilation and high occupant density. Thus, ventilation capacity is an important factor influencing airborne transmission in URDs, which should be evaluated as part of efforts to fight COVID-19 and guide healthy city planning and implementation. Here, we develop and test systematic methods to map URDs in a typical city in northern China and quantify their ventilation capacity using very high-resolution remote sensing images. Four fundamental spatial forms of URD are identified in the research area: the point-group form, parallel form, enclosed form, and hybrid form. Our analyses indicate that the integrated ventilation capacities for well-designed URDs are nearly twice those of poorly designed URDs. Large variations in ventilation capacity are also observed within URDs, with up to 13.42 times difference between the buildings. Therefore, very high-resolution remote sensing data are fundamental for extracting building height and generating precise spatial forms, which can improve the micro-scale URD ventilation planning for the prevention of COVID-19.

Developing a Health-Spatial Indicator System for a Healthy City in Small and Midsized Cities.

A recent examination of the significant role of public health has prompted calls to re-investigate how the urban environment affects public health. A vital part of the solution includes Healthy City initiatives that have been the subject of extensive policies, implications, and practices globally. However, the existing literature mainly focuses on big cities and metropolitan areas, while investigations into small and midsized cities (SMCs) are lacking, and thus reflect the underlying issues of health inequity. This study develops an indicator system for evaluating Healthy City initiatives in SMCs, linking urban design and public health, supported by the analyzed opinions from experts collected using both questionnaires and interviews. The indicator system includes six primary dimensions and 37 variables: urban form and transportation (UFT); health-friendly service (HFS); environmental quality and governance (EQG); community and facility (CF); green and open space (GOS); and ecological construction and biodiversity (ECB). A fuzzy synthetic evaluation technique was used to assess the relative importance of factors, emphasizing the importance of UFT, HFS, and EQG, with importance indexes of 0.175, 0.174, and 0.174, respectively. This indicator system is helpful for SMCs seeking to construct a Healthy City in the future, and is based on urban design and governance inputs and for enhancing the Healthy City knowledge base of cities of varied scales.

Engaging Diverse Community Groups to Promote Population Health through Healthy City Approach: Analysis of Successful Cases in Western Pacific Region.

BACKGROUND: A substantial global burden of health can be attributed to unhealthy lifestyles and an unhealthy living environment. The concept of a Healthy City is continually creating and improving physical and social environments to enable healthy living. The aim of this paper is to investigate how the Healthy City concept would tackle the complexity of health by addressing the socio-economic and political determinants of health in the Western Pacific Region. METHODS: The SPIRIT model adopted by the Alliance for Healthy Cities can provide a framework for an integrated and holistic approach to enable policy, environment, social matters, behaviours, and bio-medical interventions to take their rightful place side by side. The performance of cities awarded by the AFHC was analysed under each domain of the SPIRIT model to show the efforts striving to acquire the qualities of a healthy city. FINDINGS: Two cities have incorporated the Healthy City concept in most of their policies outside the health sector, with a high level of commitment from city leaders and citizens, so the Health City activities were recognised as part of the means to advance the cityies' general planning. One city has made use of its strong network of key stakeholders from different sectors and disciplines to establish a "Medical-Social-Community' model. All three cities have collected health information to reflect health status, determinants of health and issues reflecting health promotion to enable the creation of a city health profile and show positive changes in health. The cities have engaged key stakeholders to launch a variety of health-promoting programmes according to the needs of the population. CONCLUSION: The AFHC can play an important role in linking the cities with strong action in Healthy City activities to support other cities in Healthy City development.

SNS Big Data Analysis Framework for COVID-19 Outbreak Prediction in Smart Healthy City.

Nowadays, the world is experiencing a pandemic crisis due to the spread of COVID-19, a novel coronavirus disease. The contamination rate and death cases are expeditiously increasing. Simultaneously, people are no longer relying on traditional news channels to enlighten themselves about the epidemic situation. Alternately, smart cities citizens are relying more on Social Network Service (SNS) to follow the latest news and information regarding the outbreak, share their opinions, and express their feelings and symptoms. In this paper, we propose an SNS Big Data Analysis Framework for COVID-19 Outbreak Prediction in Smart Sustainable Healthy City, where Twitter platform is adopted. Over 10000 Tweets were collected during two months, 38% of users aged between 18 and 29, while 26% are between 30 and 49 years old. 56% of them are males and 44% are females. The geospatial location is USA, and the used language is English. Natural Language Processing (NLP) is deployed to filter the tweets. Results demonstrated an outbreak cluster predicted seven days earlier than the confirmed cases with an indicator of 0.989. Analyzing data from SNS platforms enabled predicting future outbreaks several days earlier, and scientifically reduce the infection rate in a smart sustainable healthy city environment.

Sociological modeling of smart city with the implementation of UN sustainable development goals.

The COVID-19 pandemic before mass vaccination can be restrained only by the limitation of contacts between people, which makes the digital economy a key condition for survival. More than half of the world's population lives in urban areas, and many cities have already transformed into "smart" digital/virtual hubs. Digital services ensure city life safe without an economy lockout and unemployment. Urban society strives to be safe, sustainable, well-being, and healthy. We set the task to construct a hybrid sociological and technological concept of a smart city with matched solutions, complementary to each other. Our modeling with the elaborated digital architectures and with the bionic solution for ensuring sufficient data governance showed that a smart city in comparison with the traditional city is tightly interconnected inside like a social "organism". Society has entered a decisive decade during which the world will change by moving closer towards SDGs targets 2030 as well as by the transformation of cities and their digital infrastructures. It is important to recognize the large vector of sociological transformation as smart cities are just a transition phase to human-centered personal space or smart home. The "atomization" of the world urban population raises the gap problem in achieving SDGs because of different approaches to constructing digital architectures for smart cities or smart homes in countries. The strategy of creating smart cities should bring each citizen closer to SDGs at the individual level, laying in the personal space the principles of sustainable development and wellness of personality.
