Assessment of urban ecosystem health and its influencing factors: a case study of Zibo City, China.

Urban ecosystem health is the foundation of sustainable urban development. It is important to know the health status of urban ecosystem and its influencing factors for formulating scientific urban development planning. Taking Zibo city as the study area, the indicators were selected from five aspects: ecosystem vigor, structure, resilience, service function and population health to establish an assessment index system of urban ecosystem health. The health level of urban ecosystem was assessed, and its changing trend was analyzed from 2006 to 2018 in Zibo. Furthermore, obstacle degree analysis and sensitivity analysis were used to quantitatively analyze the main obstacle factors and sensitivity factors affecting urban ecosystem health, so as to provide references for improving urban ecosystem health. The results showed that the health level of urban ecosystem in Zibo showed an upward trend from 2006 to 2018. The poor structure and ecological environment quality were the main obstacle factors to urban ecosystem health. The impact of changes in a single indicator on urban ecosystem health gradually decreased, but the sensitivity index of indicators had obvious differences. Urban ecosystem health was sensitive to changes in ecosystem structure and resilience. In the future, Zibo should strengthen ecological construction, optimize the industrial structure, and develop green economy to promote urban ecosystem healthy.

The Urban Environment and Cardiometabolic Health.

Urban environments contribute substantially to the rising burden of cardiometabolic diseases worldwide. Cities are complex adaptive systems that continually exchange resources, shaping exposures relevant to human health such as air pollution, noise, and chemical exposures. In addition, urban infrastructure and provisioning systems influence multiple domains of health risk, including behaviors, psychological stress, pollution, and nutrition through various pathways (eg, physical inactivity, air pollution, noise, heat stress, food systems, the availability of green space, and contaminant exposures). Beyond cardiometabolic health, city design may also affect climate change through energy and material consumption that share many of the same drivers with cardiometabolic diseases. Integrated spatial planning focusing on developing sustainable compact cities could simultaneously create heart-healthy and environmentally healthy city designs. This article reviews current evidence on the associations between the urban exposome (totality of exposures a person experiences, including environmental, occupational, lifestyle, social, and psychological factors) and cardiometabolic diseases within a systems science framework, and examines urban planning principles (eg, connectivity, density, diversity of land use, destination accessibility, and distance to transit). We highlight critical knowledge gaps regarding built-environment feature thresholds for optimizing cardiometabolic health outcomes. Last, we discuss emerging models and metrics to align urban development with the dual goals of mitigating cardiometabolic diseases while reducing climate change through cross-sector collaboration, governance, and community engagement. This review demonstrates that cities represent crucial settings for implementing policies and interventions to simultaneously tackle the global epidemics of cardiovascular disease and climate change.

[Identification and sensitization to environmental fungal spores in Lima City, Peru]. / Identificación y sensibilización a hongos ambientales en Lima, Perú.

OBJECTIVE: To identify and registry the most important fungal spores trapped in our aerobiology station, as well as to report the prevalence of skin sensitization to these allergens. METHODS: The pollen counts were made according to standardized technique with a Burkard seven days spore trap, following the American Academy of Allergy, Asthma and Immunology (AAAAI) through National Allergy Bureau (NAB) recommendations. The trap was installed on the roof of Clinica SANNA, El GOLF, San Isidro, which is 20 m high, 12°5'54"S 77°3'6"W in the west-south of the Lima urban area. The sampling period was performed from September 2020 to October 2021. Skin prick tests were carried out according to the recommendations of the Spanish Society of Allergology and Clinical Immunology (SEAIC) in 200 patients (18 to 60 years old) with symptoms of rhinoconjunctivitis and/or asthma, who were evaluated in the Allergology Service of Clinica SANNA el Golf. Allergenic extracts were applied, dust mites (Dermatophagoides pteronyssinus, Dermatophagoides farinae, Blomia tropicalis), cat and dog danders, cockroach (Periplaneta americana), grass 6 mix, weed mix, molds (Cladosporium herbarum, Alternaria alternata, Aspergillus fumigatus, Penicillium notatum, Nigrospora spp.), INMUNOTEK-Spain provided the extracts. We also tested other fungal allergens such as Fusarium spp, Stemphylium spp, Curvularia spp, a mixture of Helmintosporum/Dreschlera spp. from the DIATER-Argentina laboratory. RESULTS: We identified spores of Alternaria alternata, Cladosporium spp., Nigrospora spp., Stemphylium spp., Fusarium spp., Curvularia spp., Dreschlera/Helmintosporum spp. The patients showed sensitization to Cladosporium herbarum (14%), Fusarium spp. (13,5%), Nigrospora spp. (8%), Alternaria Alternata (7%), Stemphylium (6%), Dreschlera/Helmintosporium spp. (5,5%), Curvularia spp. (3%), Aspergillus fumigatus (2,5%). CONCLUSIONS: The inhabitants of the south-western area of the urban city of Lima are exposed to different fungal spores with allergenic potential, with a higher concentration being identified during the summer/autumn months. Cutaneous sensitization is demonstrated in variable percentages to the fungal spores identified in this aerobiological sampling. The results of this study should be expanded and compared with data in the forthcoming years, identify seasonal and annual fluctuations and extend the traps to other locations in Lima.

A Co-Created Assessment Framework to Measure Inclusive Health and Wellbeing in a Vulnerable Context in the South of Europe.

Rapid urbanisation exacerbates health and wellbeing disparities in vulnerable contexts and underscores the imperative need to develop innovative and participatory co-creation approaches to understand and address the specificities of these contexts. This paper presents a method to develop an assessment framework that integrates top-down dimensions with bottom-up perspectives to monitor the impact of inclusive health and wellbeing interventions tailored to the neighbourhood's needs in Las Palmeras, a vulnerable neighbourhood in Cordoba (Spain). Drawing upon studies in the literature examining urban health and wellbeing trends, it delineates a participatory and inclusive framework, emphasising the need for context-specific indicators and assessment tools. Involving diverse stakeholders, including residents and professionals, it enriches the process and identifies key indicators and assessment methods. This approach provides valuable insights for managing innovative solutions, aligning them with local expectations, and measuring their impact. It contributes to the discourse on inclusive urban health by advocating for participatory, context-specific strategies and interdisciplinary collaboration. While not universally applicable, the framework offers a model for health assessment in vulnerable contexts, encouraging further development of community-based tools for promoting inclusive wellbeing.

Multisectoral interventions for urban health in Africa: a mixed-methods systematic review.

Increasing evidence suggests that urban health objectives are best achieved through a multisectoral approach. This approach requires multiple sectors to consider health and well-being as a central aspect of their policy development and implementation, recognising that numerous determinants of health lie outside (or beyond the confines of) the health sector. However, collaboration across sectors remains scarce and multisectoral interventions to support health are lacking in Africa. To address this gap in research, we conducted a mixed-method systematic review of multisectoral interventions aimed at enhancing health, with a particular focus on non-communicable diseases in urban African settings. Africa is the world's fastest urbanising region, making it a critical context in which to examine the impact of multisectoral approaches to improve health. This systematic review provides a valuable overview of current knowledge on multisectoral urban health interventions and enables the identification of existing knowledge gaps, and consequently, avenues for future research. We searched four academic databases (PubMed, Scopus, Web of Science, Global Health) for evidence dated 1989-2019 and identified grey literature from expert input. We identified 53 articles (17 quantitative, 20 qualitative, 12 mixed methods) involving collaborations across 22 sectors and 16 African countries. The principle guiding the majority of the multisectoral interventions was community health equity (39.6%), followed by healthy cities and healthy urban governance principles (32.1%). Targeted health outcomes were diverse, spanning behaviour, environmental and active participation from communities. With only 2% of all studies focusing on health equity as an outcome and with 47% of studies published by first authors located outside Africa, this review underlines the need for future research to prioritise equity both in terms of research outcomes and processes. A synthesised framework of seven interconnected components showcases an ecosystem on multisectoral interventions for urban health that can be examined in the future research in African urban settings that can benefit the health of people and the planet.Paper ContextMain findings: Multisectoral interventions were identified in 27.8% of African countries in the African Union, targeted at major cities with five sectors present at all intervention stages: academia or research, agriculture, government, health, and non-governmental.Added knowledge: We propose a synthesised framework showcasing an ecosystem on multisectoral interventions for urban health that can guide future research in African urban settings.Global health impact for policy and action: This study reveals a crucial gap in evidence on evaluating the long-term impact of multisectoral interventions and calls for partnerships involving various sectors and robust community engagement to effectively deliver and sustain health-promoting policies and actions.

Community perceptions of community health worker effectiveness: Contributions to health behaviour change in an urban health district in South Africa.

BACKGROUND: Community health worker (CHW) programmes contribute towards strengthening adherence support, improving maternal and child health outcomes and providing support for social services. They play a valuable role in health behaviour change in vulnerable communities. Large-scale, comprehensive CHW programmes at health district level are part of a South African (SA) strategy to re-engineer primary healthcare and take health directly into communities and households, contributing to universal health coverage. OBJECTIVE: These CHW programmes across health districts were introduced in SA in 2010 - 11. Their overall purpose is to improve access to healthcare and encourage healthy behaviour in vulnerable communities, through community and family engagements, leading to less disease and better population health. Communities therefore need to accept and support these initiatives. There is, however, inadequate local evidence on community perceptions of the effectiveness of such programmes. METHODS: A cross-sectional descriptive study to determine community perceptions of the role and contributions of the CHW programme was conducted in the Ekurhuleni health district, an urban metropolis in SA. Members from 417 households supported by CHWs were interviewed in May 2019 by retired nurses used as fieldworkers. Frequencies and descriptive analyses were used to report on the main study outcomes of community acceptance and satisfaction. RESULTS: Nearly all the study households were poor and had at least one vulnerable member, either a child under 5, an elderly person, a pregnant woman or someone with a chronic condition. CHWs had supported these households for 2 years or longer. More than 90% of households were extremely satisfied with their CHW; they found it easy to talk to them within the privacy of their homes and to follow the health education and advice given by the CHWs. The community members highly rated care for chronic conditions (82%), indicated that children were healthier (41%) and had safer pregnancies (6%). CONCLUSION: As important stakeholders in CHW programmes, exploring community acceptance, appreciation and support is critical in understanding the drivers of programme performance. Community acceptance of the CHWs in the Ekurhuleni health district was high. The perspective of the community was that the CHWs were quite effective. This was demonstrated when they reported changes in household behaviour with regard to improved access to care through early screening, referrals and improved management of chronic and other conditions.

Reimagining Urban Spaces: Green Spaces, Obesity, and Health Resilience in an Era of Extreme Heat.

Record-breaking heat waves intensified by climate change pose both environmental and health threats, necessitating a balance between urban sustainability and well-being. Extreme heat and limited green space access are drivers of obesity prevalence, with decreased proximity to green spaces correlating with higher rates of obesity in nearby communities. In contrast, access to such green spaces fosters physical activity, well-being, and community cohesion, especially crucial in marginalized communities facing health disparities due to historical policies like redlining and underinvestment in social gathering spaces. Despite challenges, green space investment offers healthcare savings and environmental gains, necessitating a shift in perception towards viewing green spaces as essential for urban living. As heat waves persist, integrating health and sustainability in urban planning is paramount. Health and medical communities must play an active role in advocating for equitable access to urban green spaces, as they possess influential positions to address climate-related health disparities through localized advocacy.

Identifying childhood malaria hotspots and risk factors in a Nigerian city using geostatistical modelling approach.

Malaria ranks high among prevalent and ravaging infectious diseases in sub-Saharan Africa (SSA). The negative impacts, disease burden, and risk are higher among children and pregnant women as part of the most vulnerable groups to malaria in Nigeria. However, the burden of malaria is not even in space and time. This study explores the spatial variability of malaria prevalence among children under five years (U5) in medium-sized rapidly growing city of Akure, Nigeria using model-based geostatistical modeling (MBG) technique to predict U5 malaria burden at a 100 × 100 m grid, while the parameter estimation was done using Monte Carlo maximum likelihood method. The non-spatial logistic regression model shows that U5 malaria prevalence is significantly influenced by the usage of insecticide-treated nets-ITNs, window protection, and water source. Furthermore, the MBG model shows predicted U5 malaria prevalence in Akure is greater than 35% at certain locations while we were able to ascertain places with U5 prevalence > 10% (i.e. hotspots) using exceedance probability modelling which is a vital tool for policy development. The map provides place-based evidence on the spatial variation of U5 malaria in Akure, and direction on where intensified interventions are crucial for the reduction of U5 malaria burden and improvement of urban health in Akure, Nigeria.

Citizen science and social innovation as citizen empowerment tools to address urban health challenges: The case of the urban health citizen laboratory in Barcelona, Spain.

Urban health faces significant challenges due to the rapid growth of cities and the concentration of population in urban settings that have a strong impact on people's health. The approach to characterize and address these challenges requires increased societal involvement and interdisciplinary solutions to ensure their effectiveness and democratic nature. With this purpose, it is necessary to explore methodologies for citizen participation that foster a critical understanding of the environment and promote their active role in generating scientific knowledge and change. This article describes the creation of a collaborative space for experimentation and learning that, through the intersection of citizen science and social innovation, aims to engage citizens in the research and diagnosis of their local environment, as well as in the design and implementation of local solutions, while raising awareness about the main challenges to urban health. Through a collaborative and participatory framework, the community identified relevant challenges to urban health they wanted to investigate, co-designed and developed the methodology for data collection and analysis, and ultimately, they devised, designed, and implemented innovative solutions based on the scientific evidence obtained. The framework and results of this project hold potential interest for the scientific community, facilities, institutions, and society by offering an innovative and participatory approach to addressing the present and future urban health challenges.

How do urban green spaces influence heat-related mortality in elderly? A realist synthesis.

BACKGROUND: An important consequence of climate change for urban health is heat-related mortality. Vulnerable groups, especially elderly, will be the most affected. A solution put forward in many reports and policy documents is the introduction or expansion of urban green spaces. While they have a proven effect in decreasing the ambient temperature and reducing heat related mortality, the causal pathways are far from clear. Moreover, results vary for different contexts, population types and characteristics of green spaces as they are 'complex systems thrusted into complex systems'. To our knowledge, there is no systematic synthesis of the literature that examines the mechanisms by which and the circumstances under which green spaces work to decrease heat-related mortality for elderly. METHODS: We performed a realist synthesis- a theory-driven review method- to develop a complexity- and context-sensitive program theory. As a first step, a causal loop diagram was constructed which describes the possible pathways through which urban green spaces influence heat-related mortality in elderly. In a second step, one of the pathways - how they may lead to a reduction of heat-related mortality by increasing social capital - was further explored for underlying mechanisms, the context in which they work and the differentiated patterns of outcomes they generate. Literature was searched for evidence supporting or contradicting the initial programme theory, resulting in a refined theory. RESULTS: Results show how urban green space can impact on heat-related mortality in elderly by its influence on their exposure to outdoor and indoor heat, by improving their resilience as well as by affecting their access to treatment. Urban green spaces and their interactions with social capital affect the access to health information, social support, and the capacity for effective lobbying. Several mechanisms help to explain these observed demi-regularities, among others perceived behavioural control, perceived usefulness, receptiveness, ontological security, and self-interest. If and how they are triggered depends on the characteristics of the urban green space, the population, and other contextual factors. CONCLUSION: Looking into the impact of urban green spaces on heat-related mortality in elderly, researchers and policy makers should take interest in the role of social capital.

Assessing the contributions of an urban population health initiative to shift political priority towards cardiovascular health: three case studies from Brazil, Mongolia and Senegal.

BACKGROUND: The urban population health initiative was designed as a multidisciplinary, multisector programme to address cardiovascular (CV) disease, specifically hypertension and its underlying causes in the cities of Ulaanbaatar, Mongolia; Dakar, Senegal; and São Paulo, Brazil. This article aims to provide an overview of the history and dynamics of CV disease policy making in the three countries, to present the policy reform contributions of the initiative and its role in the policy agenda-setting framework/process in each country and to identify the enablers and challenges to the initiative for doing so. METHODS: A qualitative case study was conducted for each setting from November 2020 to January 2021, comprised of a document review, semi-structured in-depth interviews and unstructured interviews with stakeholders involved in the initiative. The literature review included documents from the initiative and the peer-reviewed and grey literature with a total of 188 documents screened. Interviews were conducted with 21 stakeholders. Data collection and thematic analysis was guided by (i) the Kingdon multiple streams conceptual framework with the main themes being CV disease problems, policy, politics and the role of policy entrepreneurs; and (ii) the study question inquiring on the role of the urban population health initiative at the CV disease policy level and enabling and challenging factors to advancing CV disease policy. Data were thematically analysed using the Framework Method. RESULTS: Each setting was characterized by a high hypertension and CV disease burden combined with an aware and proactive political environment. Policy outcomes attributed to the initiative were updating the guidelines and/or algorithms of care for hypertension and including revised physical and nutritional education in school curricula, in each city. Overall, the urban health initiative's effects in the policy arena, were most prominent in Mongolia and Senegal, where the team effectively acted as policy entrepreneur, promoting the solutions/policies in alignment with the most pressing local problems and in strong involvement with the political actors. The initiative was also involved in improving access to CV disease drugs at primary health levels. Its success was influenced by the local governance structures, the proximity of the initiative to the policy makers and the local needs. In Brazil, needs were expressed predominantly in the clinical practice. CONCLUSIONS: This multi-country experience shows that, although the policy and political environment plays its role in shaping initiatives, often the local priority needs are the driving force behind wider change.

Strengthening health service delivery and governance through institutionalizing 'Urban Health Atlas'-A geo-referenced Information Communication and Technology tool: Lessons learned from an implementation research in three cities in Bangladesh.

INTRODUCTION: Urban health governance in Bangladesh is complex as multiple actors are involved and no comprehensive data are currently available on infrastructure, services, or performance either in public and private sectors of the healthcare system. The Urban Health Atlas (UHA)-a novel and interactive geo-referenced, web-based visualization tool was developed in Bangladesh to provide geospatial and service information to decision makers involved in urban health service planning and governance. Our objective was to study the opportunities for institutionalization of the UHA into government health systems responsible for urban healthcare delivery and document the facilitators and barriers to its uptake. METHODS: This implementation research was carried out during 2017-2019 in three cities in Bangladesh: Dhaka, Dinajpur and Jashore. During the intervention period, six hands-on trainings on UHA were provided to 67 urban health managers across three study sites. Thirty in-depth and twelve key informant interviews were conducted to understand user experience and document stakeholder perceptions of institutionalizing UHA. RESULTS: Capacity building on UHA enhanced understanding of health managers around its utility for service delivery planning, decision making and oversight. Findings from the IDIs and KIIs suggest that UHA uptake was challenged by inadequate ICT infrastructure, shortage of human resources and lack of ICT skill among managers. Motivating key decision makers and stakeholders about the potential of UHA and engaging them from its inception helped the institutionalization process. CONCLUSION: While uptake of UHA by government health managers appears possible with dedicated capacity building initiatives, its use and regular update are challenged by multiple factors at the implementation level. A clear understanding of context, actors and system readiness is foundational in determining whether the institutionalization of health ICTs is timely, realistic or relevant.

Implementing a social work care coordination model for children and youth with special health care needs in a rural-urban health system.

This retrospective chart review examined care coordination among pediatric patients with varying levels of medical complexity who received care in a rural-urban health system. Care coordination utilization across patient acuity levels was examined for meaningful differences in frequency and duration of care coordination services. Results indicated that patients with more severe medical complexity had increased frequency and duration of care coordination services, as well as different patterns of care coordination activity utilization. This model of pediatric outpatient care coordination provides a flexible and highly targeted approach for stratification of care and services based on the needs of the individual patient.

Rural versus urban outcomes following transcatheter aortic valve implantation: The importance of the heart team.

BACKGROUND: Rural patients face known healthcare disparities and worse cardiovascular outcomes compared to urban residents due to inequitable access and delayed care. Few studies have assessed rural-urban differences in outcomes following Transcatheter Aortic Valve Implantation (TAVI). We compared short-term post-TAVI outcomes between rural and urban patients. METHODS: We performed a retrospective analysis of n = 413 patients who underwent TAVI at our large academic medical center, between 2011 and 2020 (rural/urban patients = 93/320. Rural/urban males = 53/173). Primary outcomes were all-cause mortality and cardiovascular mortality. Secondary outcomes included stroke/transient ischemic attack, myocardial infarction, atrial fibrillation, acute kidney injury, bleeding, vascular complications, and length of stay. RESULTS: The mean age in years was 77 [IQR 70-82] for rural patients and 78 [IQR 72-84] for urban patients. Baseline characteristics were similar between groups, except for a greater frequency of active smokers and diabetics as well as a greater body mass index in the rural group. There were no statistically significant differences in all-cause or cardiovascular mortality between the groups. There was also no statistically significant difference in secondary outcomes. CONCLUSION: Rural and urban patients had no statistically significant difference in all-cause mortality or cardiovascular mortality following TAVI. Given its minimally invasive nature and quality-centric, multidisciplinary care provided by the TAVI Heart Teams, TAVI may be the preferred modality for the treatment of severe aortic stenosis in rural populations.

Food environment of bus terminals in the Rio de Janeiro metropolitan region / Ambiente alimentar de terminais rodoviários da região metropolitana do Rio de Janeiro

ABSTRACT PURPOSE To describe and analyze the healthiness of formal and informal food establishments in bus terminals of the metropolitan region of the state of Rio de Janeiro. METHOD An audit was conducted in 156 formal and 127 informal food establishments located in 14 bus terminals of the five most populous cities of the metropolitan region of Rio de Janeiro. Proportions of types of establishments and means (95%CI) of food availability indicators in formal and informal settings were calculated. For the formal setting, prices, proportions of accepted payment methods, days and hours of operation, and food categories with displayed advertising were described. RESULTS The healthiness of food establishments in bus terminals was low (less than 36%). On average, ultra-processed food subgroups were 250% more available for purchase than fresh or minimally processed food. Purchasing food at these places was convenient because several forms of payment were available, and the opening hours of the establishments followed the peaks of movement. In addition, 73.3% of the advertising referred to ultra-processed drinks, and the cost-benefit of buying ultra-processed food was better than fresh or minimally processed food. CONCLUSION The food environment of bus terminals in the metropolitan region of Rio de Janeiro promotes unhealthy eating. Regulatory public policies should focus on initiatives to limit the wide availability and advertising of ultra-processed food in spaces of great circulation of people.

RESUMO OBJETIVO Descrever e analisar a saudabilidade dos estabelecimentos com venda formal e informal de alimentos em terminais rodoviários da região metropolitana do Rio de Janeiro. MÉTODOS Realizou-se auditoria em 156 estabelecimentos formais e 127 pontos informais de venda de alimentos localizados em 14 terminais rodoviários das cinco cidades mais populosas da região metropolitana do Rio de Janeiro. Foram calculadas proporções de tipos de estabelecimentos e médias (IC95%) de indicadores de disponibilidade de alimentos nos ambientes formal e informal. Para o ambiente formal, foram descritos preços, proporções das formas de pagamento aceitas, dias e horários de funcionamento e categorias de alimentos com propaganda exposta. RESULTADOS A saudabilidade dos pontos de venda de alimentos nos terminais rodoviários era baixa (inferior a 36%). Em média, estavam disponíveis para compra 250% mais subgrupos de alimentos ultraprocessados do que in natura ou minimamente processados. Adquirir comida nesses locais era conveniente porque diversas formas de pagamento estavam disponíveis e os horários de funcionamento dos estabelecimentos acompanhavam os picos de movimentação. Além disso, 73,3% das propagandas se referiam a bebidas ultraprocessadas e o custo-benefício da compra de alimentos ultraprocessados era melhor que o de alimentos in natura ou minimamente processados. CONCLUSÃO O ambiente alimentar dos terminais rodoviários da região metropolitana do Rio de Janeiro promove uma alimentação não saudável. Políticas públicas de regulação devem se concentrar em iniciativas que limitem a ampla disponibilidade e publicidade de alimentos ultraprocessados nesses espaços de grande circulação de pessoas.

A Survey on Factors Affecting Knowledge and Satisfaction with Care Among Persons with Diabetes Mellitus in an Urban Health Centre and its Outreach Clinics in South India.

Objective: To determine the level of knowledge and factors affecting knowledge and satisfaction with diabetes care among persons with diabetes at urban health centre (UHC) and community health worker (CHW)-led outreach clinics (ORC) in South India. Methodology: A cross-sectional study was carried out using a structured questionnaire. One hundred patients at the UHC and 200 patients at the ORC were included. Results: Patients with DM of more than eight years, with co-morbidities and maintained on insulin had good knowledge at the UHC. At the ORC, participants who received education beyond the primary level and belonging to non - Hindu religion had higher knowledge. Patients at the ORC experienced better satisfaction in terms of waiting time for appointments, consultation, registration system and counselling. At the UHC, those who received primary education or those with lower educational attainment had better satisfaction. Overall, knowledge (p = 0.03) and satisfaction (p = 0.00001) of diabetes care was better at the ORC than at the UHC. Conclusions: Our study found better knowledge and satisfaction with diabetes care at the ORC than at the UHC. Whether or not the difference can be attributed to CHW-based clinics in the community needs to be further elucidated.

Helicobacter pylori infection prevalence declined among an urban health check-up population in Chengdu, China: a longitudinal analysis of multiple cross-sectional studies.

Objectives: The efficacy of updated health policy in improving the generalization of Helicobacter pylori screening and eradication in southwest China was assessed in a longitudinal analysis of multiple cross-sectional studies from an institution. Methods: In the periods 2009-2010, 2013-2014, and 2019-2021, 8,365, 16,914, and 18,281 urban observations from health check-ups at West China Hospital were analyzed, respectively. The 14C-urea or 13C-urea breath test was consistently used for H. pylori detection. The protocol has been reported elsewhere (PROSPERO Registration number: CRD42019120764). Results: The overall prevalence of H. pylori dramatically decreased from 53.1% to 30.7% over the past decade (OR = 0.39, 95% CI 0.37-0.41), with a similar decline in all sex-specific and age-specific subgroups. The age-specific prevalence consistently increased before 40 years of age and always peaked at 50-59 years. Longitudinal clearance increased along with aging, and prevalence dropped to 22.6%, 25.1%, and 23.6% in the 40-49, 50-59, and 60-69 years initial age groups, respectively. Conclusion: The generalization of H. pylori screening and eradication could greatly contribute to the control of H. pylori infection among urban health check-up populations and lower gastric cancer incidence.
