RESUMO
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.

Nearly 56% of the global population lives in cities, with this number expected to increase to 6.6 billion or >70% of the world's population by 2050. Given that cardiometabolic diseases are the leading causes of morbidity and mortality in people living in urban areas, transforming cities and urban provisioning systems (or urban systems) toward health, equity, and economic productivity can enable the dual attainment of climate and health goals. Seven urban provisioning systems that provide food, energy, mobility-connectivity, housing, green infrastructure, water management, and waste management lie at the core of human health, well-being, and sustainability. These provisioning systems transcend city boundaries (eg, demand for food, water, or energy is met by transboundary supply); thus, transforming the entire system is a larger construct than local urban environments. Poorly designed urban provisioning systems are starkly evident worldwide, resulting in unprecedented exposures to adverse cardiometabolic risk factors, including limited physical activity, lack of access to heart-healthy diets, and reduced access to greenery and beneficial social interactions. Transforming urban systems with a cardiometabolic health-first approach could be accomplished through integrated spatial planning, along with addressing current gaps in key urban provisioning systems. Such an approach will help mitigate undesirable environmental exposures and improve cardiovascular and metabolic health while improving planetary health. The purposes of this American Heart Association policy statement are to present a conceptual framework, summarize the evidence base, and outline policy principles for transforming key urban provisioning systems to heart-health and sustainability outcomes.

Hepatitis C virus (HCV) causes significant mortality worldwide. HCV is highly curable but access to care is limited for many patients. The Grady Liver Clinic (GLC), a primary care-based HCV clinic, utilizes a multidisciplinary team to provide comprehensive care for a medically underserved patient population in Atlanta, Georgia. The GLC added a telehealth option for HCV treatment at the start of the COVID-19 pandemic. We describe the outcomes of utilizing telehealth in this population. We performed a retrospective chart review of patients who initiated HCV treatment from March 2019 to February 2020 (pre-pandemic) and March 2020 to February 2021 (pandemic). Charts were abstracted for patient demographics and characteristics, treatment regimen, and treatment outcomes. Our primary outcome was HCV cure rate of the pre-pandemic compared to the pandemic cohorts and within the different pandemic cohort visit types. We performed an intention-to-treat (ITT) analysis for all patients who took at least one dose of a direct-acting antiviral (DAA) regardless of therapy completion, and a per-protocol (PP) analysis of those who completed treatment and were tested for HCV cure. SVR12 rates were >95% on ITT analysis, with no significant difference between pre-pandemic and pandemic cohorts. There was also no significant difference within the pandemic group when treatment was provided traditionally, via telehealth, or via a hybrid of these. Our findings support the use of telehealth as a tool to expand access to HCV treatment in a medically underserved patient population.

Hepatitis C virus core antigen (HCVcAg) testing can simplify and decrease costs of HCV infection confirmation compared to molecular testing (nucleic acid testing). We piloted HCVcAg testing for the confirmation of active infection. The study was conducted during June through December 2022 among the police and the general population of Islamabad, Pakistan age 18 years and older. Initial screening for HCV antibody was conducted using a rapid diagnostic test (RDT) for all consenting participants. Those who tested positive had venous blood samples tested for HCVcAg, platelets and aspartate aminotransferase (AST). Persons with HCVcAg values ≥3 fmol/L were defined as viremic, and they were offered treatment with direct acting antiviral (DAA) medications, sofosbuvir and daclatasvir. Aspartate aminotransferase to platelet ratio index (APRI) was calculated for each HCV infected person, and those with an APRI score <1.5 received treatment for 12 weeks, while those with APRI ≥ to 1.5 received 24 weeks of treatment. A total of 15,628 persons were screened for anti-HCV using RDT and 643 (4.1%) tested positive. HCVcAg values of ≥3 fmol/L was found in 399/643 (62.1%), and all were offered and accepted treatment. Of those treated, 273/399 (68.4%) returned for a follow-up SVR and HCVcAg was not detected in 261/273, a 95.6% cure rate. The pilot study demonstrated the effectiveness of reaching and treating an urban population using RDT for screening and HCVcAg for confirmation of infection and test of cure.

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.

OBJECTIVES: Indonesia is the fifth country with the highest number of preterm births worldwide. More than a third of neonatal deaths in Indonesia were attributed to preterm birth. Residential areas affected the occurrence of preterm birth due to differing socioeconomic and environmental conditions. Many studies have investigated the determinants of prematurity in Indonesia, however, most of them were performed in rural areas. This study is the first meta-analysis describing the determinants of preterm birth in urban Indonesia, which aimed to become the foundation upon implementing the most suitable preventative measure and policy to reduce the rate of preterm birth. METHODS: We collected all published papers investigating the determinants of preterm birth in urban Indonesia from PubMed MEDLINE and EMBASE, using keywords developed from the following key concepts: "preterm birth", "determinants", "risk factors", "Indonesia" and the risk factors, such as "high-risk pregnancy", "anemia", "pre-eclampsia", and "infections". Exclusion criteria were multicenter studies that did not perform a specific analysis on the Indonesian population or did not separate urban and rural populations in their analysis, and articles not available in English or Indonesian. The Newcastle Ottawa Scale was used to assess the risk of bias. This systematic review was registered in PROSPERO. RESULTS: Sixteen articles were included in the analysis and classified into five categories: genetic factors, nutrition, smoking, pregnancy characteristics or complications, and disease-related characteristics. CONCLUSIONS: Our meta-analysis revealed adolescent pregnancy, smoking, eclampsia, bacterial vaginosis, LC-PUFA, placental vitamin D, and several minerals as the significant determinants of preterm birth in urban Indonesia.

OBJECTIVE: Cardiovascular diseases are the leading global cause of death. Due to the disparities in cardiovascular risk factors between rural and urban populations, this study aims to assess the differences in the prevalence of risk factors in urban and rural areas of eastern Croatia. METHODS: The cross-sectional study included 280 participants (140 from urban and 140 from rural areas) registered at studied general practice offices. Methods included e-health records, questionnaire, physical examination methods, and blood sampling for laboratory tests. RESULTS: The most common risk factors among participants were elevated total cholesterol (83.6%), elevated LDL cholesterol (81.8%), increased body mass index (75.0%), increased waist-hip ratio (82.9%), increased waist circumference (63.2%), and arterial hypertension (70.1%). The rural participants had a significantly higher prevalence of arterial hypertension (p = 0.023), increased body mass index (p = 0.004), increased waist circumference (p = 0.004), increased waist-hip ratio (p < 0.001), and increased LDL cholesterol (p = 0.029), while the urban participants had a significantly higher prevalence of insufficient physical activity (p < 0.001). CONCLUSIONS: In the examined sample, the prevalence of cardiovascular risk factors is generally high. Participants from rural areas are significantly more susceptible to cardiovascular risk factors than participants from urban areas.

Background and Objectives: Genomic studies have identified several SNP loci associated with schizophrenia in East Asian populations. Environmental factors, particularly urbanization, play a significant role in schizophrenia development. This study aimed to identify schizophrenia susceptibility loci and characterize their biological functions and molecular pathways in Taiwanese urban Han individuals. Materials and Methods: Participants with schizophrenia were recruited from the Taiwan Precision Medicine Initiative at Tri-Service General Hospital. Genotype-phenotype association analysis was performed, with significant variants annotated and analyzed for functional relevance. Results: A total of 137 schizophrenia patients and 26,129 controls were enrolled. Ten significant variants (p < 1 × 10-5) and 15 expressed genes were identified, including rs1010840 (SOWAHC and RGPD6), rs11083963 (TRPM4), rs11619878 (LINC00355 and LINC01052), rs117010638 (AGBL1 and MIR548AP), rs1170702 (LINC01680 and LINC01720), rs12028521 (KAZN and PRDM2), rs12859097 (DMD), rs1556812 (ATP11A), rs78144262 (LINC00977), and rs9997349 (ENPEP). These variants and associated genes are involved in immune response, blood pressure regulation, muscle function, and the cytoskeleton. Conclusions: Identified variants and associated genes suggest a potential genetic predisposition to schizophrenia in the Taiwanese urban Han population, highlighting the importance of potential comorbidities, considering population-specific genetic and environmental interactions.

BACKGROUND: Sepsis surveillance using electronic health record (EHR)-based data may provide more accurate epidemiologic estimates than administrative data, but experience with this approach to estimate population-level sepsis burden is lacking. METHODS: This was a retrospective cohort study including all adults admitted to publicly-funded hospitals in Hong Kong between 2009-2018. Sepsis was defined as clinical evidence of presumed infection (clinical cultures and treatment with antibiotics) and concurrent acute organ dysfunction (≥2 point increase in baseline SOFA score). Trends in incidence, mortality, and case fatality risk (CFR) were modelled by exponential regression. Performance of the EHR-based definition was compared with 4 administrative definitions using 500 medical record reviews. RESULTS: Among 13,550,168 hospital episodes during the study period, 485,057 (3.6%) had sepsis by EHR-based criteria with 21.5% CFR. In 2018, age- and sex-adjusted standardized sepsis incidence was 759 per 100,000 (relative +2.9%/year [95%CI 2.0, 3.8%] between 2009-2018) and standardized sepsis mortality was 156 per 100,000 (relative +1.9%/year [95%CI 0.9,2.9%]). Despite decreasing CFR (relative -0.5%/year [95%CI -1.0, -0.1%]), sepsis accounted for an increasing proportion of all deaths (relative +3.9%/year [95%CI 2.9, 4.9%]). Medical record reviews demonstrated that the EHR-based definition more accurately identified sepsis than administrative definitions (AUC 0.91 vs 0.52-0.55, p < 0.001). CONCLUSIONS: An objective EHR-based surveillance definition demonstrated an increase in population-level standardized sepsis incidence and mortality in Hong Kong between 2009-2018 and was much more accurate than administrative definitions. These findings demonstrate the feasibility and advantages of an EHR-based approach for widescale sepsis surveillance.
RESUMO
INTRODUCTION: Rural versus urban living is a social determinant of cognitive health. We estimated the association of rural versus urban residence in the USA with incident cognitive impairment (ICI) and assessed effect heterogeneity by sociodemographic, behavioral, and clinical factors. METHODS: The Reasons for Geographic and Racial Differences in Stroke Study (REGARDS) is a population-based prospective observational cohort of 30,239 adults, 57% female, 36% Black, aged 45+ years, sampled from 48 contiguous states in the USA in 2003-2007. We analyzed 20,878 participants who at baseline were cognitively intact with no history of stroke and had ICI assessed on average 9.4 years later. We classified participants' home addresses at baseline as urban (population ≥50,000), large rural (10,000-49,999), or small rural (≤9,999) by Rural-Urban Commuting Area codes. We defined ICI as ≥1.5 SD below the mean on at least 2 of the following tests: word list learning, word list delayed recall, and animal naming. RESULTS: Participants' home addresses were 79.8% urban, 11.7% large rural, and 8.5% small rural. ICI occurred in 1,658 participants (7.9%). Small rural residents had higher odds of ICI than urban residents, adjusted for age, sex, race, region, and education (OR = 1.34 [95% CI: 1.10, 1.64]), and after further adjustment for income, health behaviors, and clinical characteristics (OR = 1.24 [95% CI: 1.02, 1.53]). Former smoking versus never, nondrinking versus light alcohol drinking, no exercise versus ≥4 times/week, CES-D depressive symptom score of 2 versus 0, and fair versus excellent self-rated health had stronger associations with ICI in small rural areas than in urban areas. For example, in urban areas, lack of exercise was not associated with ICI (OR = 0.90 [95% CI: 0.77, 1.06]); however, lack of exercise combined with small rural residence was associated with 1.45 times the odds of ICI compared with ≥4 bouts of exercise/week in urban areas (95% CI: 1.03, 2.03). Overall, large rural residence was not associated with ICI; however, black race, hypertension, and depressive symptoms had somewhat weaker associations with ICI, and heavy alcohol drinking a stronger association with ICI, in large rural areas than in urban areas. CONCLUSION: Small rural residence was associated with ICI among USA adults. Further research to better understand why rural residents are at higher risk for developing ICI and mechanisms to ameliorate that risk will support efforts to advance rural public health.

Cities have been envisioned as biological organisms as the integral part of nature's energy and material flows. Recent advances in urban scaling research have uncovered systematic changes in socioeconomic rates and infrastructural networks as urban population increases, providing predictive contents for the comparison between cities and organisms. However, it is still unclear how and why larger and smaller cities may differ in their per capita environmental impacts. Here, we study scaling patterns of urban energy, water, and waste flows as well as other relevant measures in Chinese cities. We divide cities into different groups using an algorithm that automatically assigns cities to clusters with distinct scaling patterns. Despite superlinear scaling of urban GDP, as predicted by urban scaling theories, resource consumption, such as the supply of electricity and water, and waste generation, such as wastewater and domestic waste, do not show significant deviations from linear scaling. The lengths of resource pipelines scale linearly in most cases, as opposed to sub-linearity predicted by theory. Furthermore, we show two competing forces underlying the overall observed effects of scale: a higher population density tends to decrease per capita resource consumption and infrastructure provisions, while intensified socioeconomic activities have the opposite effect.

BACKGROUND: A high burden of bacterial skin infections (BSI) is well documented in remote-living Indigenous children and young people (CYP) in high-income countries (HIC). Atopic dermatitis (AD) is the most common chronic inflammatory skin condition seen in CYP and predisposes to BSI. Despite the rate of urbanization for Indigenous people increasing globally, research is lacking on the burden of AD and BSI for urban-living Indigenous CYP in HIC. Indigenous people in HIC share a history of colonization, displacement and subsequent ongoing negative impacts on health. OBJECTIVE: To provide a global background on the burden of AD and BSI in urban-living Indigenous CYP in HIC. METHODS: A systematic review of primary observational studies on AD and BSI in English containing epidemiologic data was performed. MEDLINE, EMBASE, EMCARE, Web of Science, and PubMed databases were searched for articles between January 1990 and December 2021. RESULTS: From 2278 original manuscripts, 16 were included: seven manuscripts documenting eight studies on AD; and nine manuscripts documenting nine studies on BSI. Current and severe symptoms of AD were more common in urban-living Indigenous CYP in HIC compared with their non-Indigenous peers, with children having a higher prevalence than adolescents. Urban-living Indigenous CYP in HIC had a higher incidence of all measures of BSI compared with their non-Indigenous peers, and were over-represented for all measures of BSI compared with their proportion of the background population. Limitations include incomplete representation of all Indigenous populations in HIC. CONCLUSION: A significant burden of AD and BSI exists in urban-living Indigenous CYP in HIC.

OBJECTIVE: To assess the association between residence place, socioeconomic conditions and oral health-related quality of life (OHRQoL) among schoolchildren from southern Brazil. METHODS: Participants were 9-14-year-old schoolchildren from rural and urban municipal schools from Rosário do Sul, Brazil. The Child Perceptions Questionnaire (CPQ11-14) was used to assess OHRQoL. A structured questionnaire collected data on sociodemographic condition (family income), residence place (urban or rural), use of dental services, and behavioral variables. Clinical oral examination recorded the presence of missing teeth and the gingival bleeding index. Multilevel Poisson regression analysis with a hierarchical approach assessed the association between predictors and CPQ11-14 scores. Rate ratios (RR) and 95% confidence intervals (CI) were estimated. RESULTS: A total of 373 schoolchildren were included (rural area=122; urban area=251), with a mean CPQ11-14 score of 11.83, ranging from 0 to 42. Low-income schoolchildren living in rural areas had 15% higher CPQ11-14 scores than high-income schoolchildren living in urban areas. In urban areas, family income predicted OHRQoL, with low-income schoolchildren having 9% higher CPQ11-14 scores than high-income children. In rural areas, schoolchildren with low household income had 19% higher CPQ11-14 scores than high-income children. CONCLUSION: Schoolchildren from low-income families had a poorer OHRQoL irrespective of their area of residence (rural or urban). The association between family income and OHRQoL was more pronounced among children living in rural areas.

BACKGROUND: The development and implementation of appropriate strategies to enhance oral health in the community can be aided by an understanding of oral healthcare seeking behavior among urban and rural populations. The purpose of this study was to identify the factors associated with oral healthcare seeking behavior of the Malaysians in urban and rural locations who self-reported dental problems. METHODS: The National Health and Morbidity Survey 2019, a cross-sectional nationwide household survey that focused on non-institutionalised Malaysians, provided the data for this study on adults in Malaysia who were 18 years of age and older. A two-stage stratified random sampling technique was employed to ensure national representativeness. Data was collected using a multilingual (Malay and English), structured, and validated questionnaire via face-to-face interviews from July to October 2019. The dependent variable was oral healthcare seeking behavior (sought oral healthcare and self-medication). Independent variables were predisposing, enabling and health needs factor based on Andersen's Behavioral Model. Descriptive statistics were used to describe the characteristics and oral healthcare seeking behavior of the respondents. The relationship between the independent and dependent variables were investigated using multivariable logistic regression analysis. RESULTS: The analysis comprised a total of 10,134 respondents, representing about 18.2 million Malaysian adults aged 18 and above. The overall prevalence of Malaysian adults who self-reported dental problems was low (5.5%) and was slightly higher in the rural than urban population. Almost half sought treatment from healthcare practitioners, and almost a quarter self-medicated. Ethnicity was associated with seeking healthcare and self-medication among urban dwellers. Among the rural population, income level was associated with seeking healthcare while education level was associated with self-medication. CONCLUSION: Disparities in oral healthcare seeking behaviors exist between Malaysians living in urban and rural areas. Future policies should adopt focused strategies that concentrate on oral healthcare accessibility and health literacy of the vulnerable and rural populations to achieve the best oral healthcare for this population group.

OBJECTIVE: To project total fertility rates for urban and rural areas in Pakistan up to 2027 with 80% prediction intervals. METHODS: The secondary-data study was conducted from March 2020 to August 2020 at Data Bank in the Department of Statistics, University of Karachi, Pakistan, and comprised publicly available data of the Pakistan Demographic Survey from 1984 to 2007. Two statistical models, the functional time series model and the coherent functional model, were used to make the predictions about age-specific fertility rates. The forecasting performance of the models was compared through error measures. Data was analysed using R version 3.6.3. RESULTS: The predicted total fertility rate was 1.7 (80% prediction interval: 0.4-4.4) births per woman for urban areas and 2.2 (80% prediction interval: 0.6-5.3) births per woman for rural areas in 2027 using coherent functional model. The total fertility rate predicted by the functional time series model was 2.1 (80% prediction interval: 1.6- 2.6) births in urban areas and 2.7 (80% prediction interval: 1.7-4.1) births per woman in rural areas. The empirical comparison of forecast error measures obtained from the two models indicated that the coherent functional model performed better for forecasting total fertility rates for urban and rural areas in Pakistan. CONCLUSIONS: The projection of fertility rate obtained by the functional time series model and the coherent functional model described the future fertility behaviour of urban and rural populations.

OBJECTIVE: Excessive salt intake is associated with higher levels of AHT and prevalence of cardiovascular diseases. WHO recommends consuming less than 5 g/day of salt (equivalent to 2 g Na+/day). Identifying foods and behaviours with greater contribution to excess intake would facilitate preventive dietary advice. DESIGN: Observational study. SITE: Urban Health Center in Cáceres. MAIN MEASUREMENTS: We estimated salt consumption using two food consumption frequency (FFQ) questionnaires, one generic and one with high Na+ content, and a 24 h follow-up survey. We use the Evalfinut program for nutritional evaluation of the diet. We analyzed correlations between estimated salt intake and 24-h urine sodium elimination (gold standard). RESULTS: 92% of the population had consumption higher than the recommendations with intakes equivalent to 9.5 g/day of salt (3.7 g/d of Na+). When sodium intake is determined by the Na+/K+ ratio, 79.54% have high intakes. Sodium elimination follows a slightly increasing trend with BMI. The perception of salt consumption is low, 56.3% consider it "adequate". 32.4% add salt to food once served. FFQ underestimate Na+ intake and targeted surveys provide higher values. The correlation between FFQ and Na+ urinary elimination is weak. CONCLUSION: We must reduce salt intake by increasing the perception of consumption, improving knowledge about the salt content in food and identifying target patients of the health council.

BACKGROUND: Breast cancer survivors experience altered body image and quality of life (QoL) due to the disease and its treatment. The multidimensional nature of body image and QoL makes their relationships complex. This study aimed to examine the associations between the two concepts in Chinese breast cancer survivors and test whether these associations are moderated by rural-urban residence. METHODS: A cross-sectional design was adopted. Breast cancer survivors were recruited via a convenience sampling method. Two validated questionnaires (the Body Image Self-Rating Questionnaire for Breast Cancer and 36-item Short-Form Health Survey) and questions assessing demographic and clinical covariates were administered. Multiple linear regressions were used to assess the relationship between body image and QoL domains and to examine the moderating effect of rural-urban residence. RESULTS: In our sample of 354 breast cancer survivors, half (50.28%) lived in rural areas. After adjusting for demographic and clinical variables, better perception of body image-related sexual activity change, role change, and psychological change was significantly associated with better physical (ß ranged from - 0.15 to - 0.11, p < 0.05) and mental (ß ranged from - 0.46 to - 0.34, p < 0.001) well-being. Better perception of body image-related social and behavior change was significantly associated only with better mental well-being (ß ranged from - 0.40 to - 0.33, p < 0.001). The association between body image and mental well-being was much stronger in urban subjects (b = - 0.38, p < 0.001) than in rural subjects (b = - 0.20, p < 0.001). CONCLUSIONS: Our findings suggest that multidimensional body image is associated with physical and mental well-being in Chinese breast cancer survivors. Body image appears to play a larger role in urban breast cancer survivors' mental well-being. Our results indicate that incorporating interventions that address body image issues would be advantageous for survivorship care to enhance QoL in breast cancer survivors. Furthermore, rural-urban differences should be considered in the strategic design of survivorship care programs in rural and urban settings.

BACKGROUND: COVID-19 related stigma has been identified as a critical issue since the beginning of the pandemic. We developed a valid and reliable questionnaire to measure COVID-19 related enacted stigma, inflicted by the non-infected general population. We applied the questionnaire to measure COVID-19 related enacted stigma among Tehran citizens from 27 to 30 September 2020. METHODS: A preliminary questionnaire with 18 items was developed. The total score ranged from 18 to 54; a higher score indicated a higher level of COVID-19 related stigma. An expert panel assessed the face and content validity. Of 1637 randomly recruited Tehran citizens without a history of COVID-19 infection, 1064 participants consented and were interviewed by trained interviewers by phone. RESULTS: Item content validity index (I-CVI), Item content validity ratio (I-CVR), and Item face validity index (I-FVI) were higher than 0.78 for all 18 items. The content and face validity were established with a scale content validity index (S-CVI) of 0.90 and a scale face validity index (S-CVI) of 93.9%, respectively. Internal consistency of the questionnaire with 18 items was confirmed with Cronbach's alpha of 0.625. Exploratory factor analysis revealed five latent variables, including "blaming", "social discrimination", "dishonor label", "interpersonal contact", and "retribution and requital attitude". The median of the stigma score was 24 [25th percentile: 22, 75the percentile: 28]. A large majority (86.8%) of participants reported a low level of stigma with a score below 31. None of the participants showed a high level of stigma with a score above 43. We found that the higher the educational level the lower the participant's stigma score. CONCLUSION: We found a low level of stigmatizing thoughts and behavior among the non-infected general population in Tehran, which may be due to the social desirability effect, to the widespread nature of COVID-19, or to the adaptation to sociocultural diversity of the large city.

Determinants at the contextual level are important for children's and adolescents' mental health care utilization, as this is the level where policy makers and care providers can intervene to improve access to and provision of care. The objective of this review was to summarize the evidence on contextual determinants associated with mental health care utilization in children and adolescents. A systematic literature search in five electronic databases was conducted in August 2021 and retrieved 6439 unique records. Based on eight inclusion criteria, 74 studies were included. Most studies were rated as high quality (79.7%) and adjusted for mental health problems (66.2%). The determinants that were identified were categorized into four levels: organizational, community, public policy or macro-environmental. There was evidence of a positive association between mental health care utilization and having access to a school-based health center, region of residence, living in an urban area, living in an area with high accessibility of mental health care, living in an area with high socio-economic status, having a mental health parity law, a mental health screening program, fee-for-service plan (compared to managed care plan), extension of health insurance coverage and collaboration between organizations providing care. For the other 35 determinants, only limited evidence was available. To conclude, this systematic review identifies ten contextual determinants of children's and adolescents' mental health care utilization, which can be influenced by policymakers and care providers. Implications and future directions for research are discussedPROSPERO ID: CRD42021276033.
RESUMO
Objective: Identify mechanisms reported in primary health care (PHC) interventions in rural and marginal urban populations from 1997 to 2019. Methods: A scoping review was used to identify the literature. The literature search was conducted using the Medline (PubMed and Ovid), Global Health, Embase, Web of Science, Scopus, and Lilacs databases. Inclusion criteria considered literature on primary intervention and observational studies using qualitative, quantitative, or mixed methods. Articles in English, Portuguese, and Spanish published from 1997 to 2019 were included. Rayyan QCRI was used for definitive document selection; sources of information from gray literature or research in progress were excluded. Results: At the individual level, three groups of mechanisms were identified: levels of relationships between interventions and subjects, transformations that can occur in individuals, and reciprocal relationships. At the institutional level, mechanisms were related to temporality, money, power relations, trust relations, the health system, expectations, and administrative conditions. Conclusions: Individual mechanisms are similar in different contexts. Institutional mechanisms are susceptible to variations in context and are expressed in terms of temporality, economic resources, power and trust relations, the health system, expectations, and administrative conditions.
Objetivo: Identificar os mecanismos relatados nas intervenções de atenção primária à saúde (APS) em populações rurais e urbanas periféricas entre 1997 e 2019. Métodos: Foi utilizado o método de revisão sistemática exploratória para identificar a literatura. A busca bibliográfica foi feita nas bases de dados Medline (Pubmed e Ovid), Global Health, Embase, Web of Science, Scopus e Lilacs. A inclusão da literatura considerou estudos de intervenção primária, observacionais, com metodologias qualitativas, quantitativas ou mistas. Foram incluídos artigos em inglês, português e espanhol publicados entre 1997 e 2019. Para a seleção dos documentos definitivos foi utilizado o Rayyan QCRI e foram excluídas fontes de informação da literatura cinzenta ou de pesquisas em andamento. Resultados: No nível individual, foram identificados três grupos de mecanismos: níveis de relações entre as intervenções e os sujeitos, transformações que podem ocorrer nos indivíduos e relações recíprocas. No nível institucional, se relacionaram a temporalidade, dinheiro, relações de poder, relações de confiança, sistema de saúde, expectativas e condições administrativas. Conclusões: Os mecanismos individuais são semelhantes nos diferentes contextos. Os mecanismos institucionais são suscetíveis à variação do contexto e estão representados na temporalidade, nos recursos econômicos, nas relações de poder e confiança, no sistema de saúde, nas expectativas e nas condições administrativas.
