RESUMO

This study aimed to evaluate the practice of physical activity (PA) among adolescents and its association with characteristics of the urban environment of Brazilian capitals. Study with adolescents from the 26 Brazilian capitals and the Federal District participating in the National School Health Survey, 2015 edition. The association between regular practice of PA (≥300 minutes/week) and the dimensions of urban well-being (urban mobility, urban environmental conditions, urban housing conditions, urban collective services, and urban infrastructure) was examined using multilevel logistic regression. A total of 50,904 adolescents were evaluated, among which 20.7% were active. It was observed in the multiple model that adolescents who live in capitals with better urban environmental conditions, such as the presence of tree coverage, less open sewage, and less accumulated garbage around the houses, are more likely to be active (OR = 1.06; 95% CI:1.01;1.12). Adolescents who live in cities with less urban disorder are more likely to be active.

RESUMO

BACKGROUND: The COVID-19 pandemic has shown how intraurban inequalities are likely to reinforce health and social inequalities. Studies at small area level help to visualize social inequialities hidden in large areas as cities or regions. AIM: To describe the spatial patterning of COVID-19 death rates in neighborhoods of the medium-sized city of Bariloche, Argentina, and to explore its relationship with the socioeconomic characteristics of neighborhoods. METHODS: We conducted an ecological study in Bariloche, Argentina. The outcome was counts of COVID-19 deaths between June 2020 and May 2022 obtained from the surveillance system and georeferenced to neighborhoods. We estimated crude- and age-adjusted death rates by neighborhood using a Bayesian approach through a Poisson regression that accounts for spatial-autocorrelation via Conditional Autoregressive (CAR) structure. We also analyzed associations of age-adjusted death rates with area-level socioeconomic indicators. RESULTS: Median COVID-19 death rate across neighborhoods was 17.9 (10th/90th percentile of 6.3/35.2) per 10,000 inhabitants. We found lower age-adjusted rates in the city core and western part of the city. The age-adjusted death rate in the most deprived areas was almost double than in the least deprived areas, with an education-related relative index of inequality (RII) of 2.14 (95% CI 1.55 to 2.96). CONCLUSION: We found spatial heterogeneity and intraurban variability in age-adjusted COVID-19 death rates, with a clear social gradient, and a higher burden in already deprived areas. This highlights the importance of studying inequalities in health outcomes across small areas to inform placed-based interventions.

RESUMO

BACKGROUND: Despite global interest in gender disparities and social determinants of hypertension, research in urban areas and regions with a high prevalence of hypertension, such as Latin America, is very limited. The objective of this study was to examine associations of individual- and area-level socioeconomic status with hypertension in adults living in 230 cities in eight Latin America countries. METHODS: In this cross-sectional study, we used harmonized data from 109,184 adults (aged 18-97 years) from the SALURBAL (Salud Urbana en America Latina/Urban Health in Latin America) project. Hypertension was assessed by self-report. Individual-, sub-city- and city-level education were used as proxies of socioeconomic status. All models were stratified by gender. RESULTS: Higher individual-level education was associated with lower odds of hypertension among women (university education or higher versus lower than primary: odds ratio [OR] = 0.67, 95% confidence interval [CI] = 0.61-0.74) but higher odds among men (OR = 1.65; 95%CI 1.47-1.86), although in men an inverse association emerged when measured blood pressure was used (OR = 0.86; 95%CI 0.76-0.97). For both genders, living in sub-city areas with higher educational achievement was associated with higher odds of hypertension (OR per standard deviation [SD] = 1.07, 95%CI = 1.02-1.12; OR = 1.11 per SD, 95%CI = 1.05-1.18, for women and men, respectively). The association of city-level education with hypertension varied across countries. In Peru, there was an inverse association (higher city level education was associated with lower odds of hypertension) in women and men, but in other countries no association was observed. In addition, the inverse association of individual-level education with hypertension became stronger (in women) or emerged (in men) as city or sub-city education increased. CONCLUSION: The social patterning of hypertension differs by gender and by the level of analysis highlighting the importance of context- and gender-sensitive approaches and policies to reduce the prevalence of hypertension in Latin America.

RESUMO

BACKGROUND: The health of a population is determined by urban factors such as the physical, social and safety environment, which can be modified by urban regeneration policies. The aim of this study was to analyze the associations of elements of the social, physical and safety environment of the neighborhood in the urban context with self-perceived health (SPH), according to axes of inequality, such as gender and educational level in Chile in 2016. METHODS: Cross-sectional study using a nationally representative population-based survey of Chile. We used data from the 2016 National Survey of Quality of Life and Health. Poor SPH in the urban population older than 25 years was analyzed in relation to social, physical and safety environment variables. Poisson multilevel regression models were estimated to obtain prevalence ratios (PR) and their respective 95% confidence intervals (95%CI). All analyses were stratified by sex and educational level. RESULTS: SPH was worse in women than in men, especially in those with a lower education level. Poor SPH was associated with lack of support networks (PR = 1.4; 95%CI = 1.1-1.7), non-participation in social organizations (PR = 1.3; 95%CI = 1.1-1.6) and perceived problems with the quality of public space (PR = 1.3; 95%CI = 1.2-1.5) in women with a medium-high educational level and with a feeling of not belonging to the neighborhood (PR = 1.5; 95%CI = 1.2-1.8) and the perception of pollution problems (PR = 1.2; 95%CI = 1.0-1.4) in women with a low educational level. A feeling of unsafety was associated with both educational levels (PR = 1.3; 95%CI = 1.0-1.5). Poor SPH was associated with the feeling of not belonging (PR = 1.7; 95%CI = 1.2-2.5), and unsafety (PR = 2.1; 95%CI = 1.8-2.4) in men with a medium-high educational level, while there were fewer associations in men with a lower education level. CONCLUSIONS: Urban interventions are recommended to improve the health of the resident population and should take into account axes of inequality.

RESUMO

Studies of life expectancy (LE) in small areas of cities are relatively common in high-income countries but rare in Latin American countries. Small-area estimation methods can help to describe and quantify inequities in LE between neighborhoods and their predictors. Our objective was to analyze the distribution and spatial patterning of LE across small areas of Ciudad Autónoma de Buenos Aires (CABA), Argentina, and its association with socioeconomic characteristics. As part of the SALURBAL project, we used georeferenced death certificates in 2015-2017 for CABA, Argentina. We used a spatial Bayesian Poisson model using the TOPALS method to estimate age- and sex-specific mortality rates. We used life tables to estimate LE at birth. We obtained data on neighborhood socioeconomic characteristics from the 2010 census and analyzed their associations. LE at birth was higher for women (median of across neighborhoods = 81.1 years) compared to men (76.7 years). We found a gap in LE of 9.3 (women) and 14.9 years (men) between areas with the highest and the lowest LE. Better socioeconomic characteristics were associated with higher LE. For example, mean differences in LE at birth in areas with highest versus lowest values of composite SES index were 2.79 years (95% CI: 2.30 to 3.28) in women and 5.61 years (95% CI: 4.98 to 6.24) in men. We found large spatial inequities in LE across neighborhoods of a large city in Latin America, highlighting the importance of place-based policies to address this gap.

RESUMO

Background: Latin America and the Caribbean (LAC) is one of the most urbanized and violent regions worldwide. Homicides in youth (15-24 years old, yo) and young adults (25-39yo) are an especially pressing public health problem. Yet there is little research on how city characteristics relate to homicide rates in youth and young adults. We aimed to describe homicide rates among youth and young adults, as well as their association with socioeconomic and built environment factors across 315 cities in eight LAC countries. Methods: This is an ecological study. We estimated homicide rates in youth and young adults for the period 2010-2016. We investigated associations of homicide rates with sub-city education and GDP, Gini, density, landscape isolation, population and population growth using sex-stratified negative binomial models with city and sub-city level random intercepts, and country-level fixed effects. Findings: The mean sub-city homicide rate per 100,000 in persons aged 15-24 was 76.9 (SD = 95.9) in male and 6.7 (SD = 8.5) in female, and in persons aged 25-39 was 69.4 (SD = 68.9) in male and 6.0 (SD = 6.7) in female. Rates were higher in Brazil, Colombia, Mexico and El Salvador than in Argentina, Chile, Panama and Peru. There was significant variation in rates across cities and sub-cities, even after accounting for the country. In fully adjusted models, higher sub-city education scores and higher city GDP were associated with a lower homicide rate among male and female (rate ratios (RR) per SD higher value in male and female, respectively, 0.87 (CI 0.84-0.90) and 0.90 (CI 0.86-0.93) for education and 0.87 (CI 0.81-0.92) and 0.92 (CI 0.87-0.97) for GDP). A higher city Gini index was associated with higher homicide rates (RR 1.28 (CI 1.10-1.48) and 1.21 (CI 1.07-1.36) in male and female, respectively). Greater isolation da was also associated with higher homicide rates (RR 1.13 (CI 1.07-1.21) and 1.07 (CI 1.02-1.12) in male and female, respectively). Interpretation: City and sub-city factors are associated with homicide rates. Improvements to education, social conditions and inequality and physical integration of cities may contribute to the reduction of homicides in the region.

RESUMO

Background: Childhood obesity is a rising global health problem. The rapid urbanization experienced in Latin America might impact childhood obesity through different pathways involving urban built and social features of cities. We aimed to evaluate the association between built and social environment features of cities and childhood obesity across countries and cities in Latin America. Methods: Cross-sectional analysis of data from 20,040 children aged 1-5 years living in 159 large cities in six Latin American countries. We used individual-level anthropometric data for excess weight (overweight or obesity) from health surveys that could be linked to city-level data. City and sub-city level exposures included the social environment (living conditions, service provision and educational attainment) and the built environment (fragmentation, isolation, presence of mass transit, population density, intersection density and percent greenness). Multi-level logistic models were used to explore associations between city features and excess weight, adjusting for age, sex, and head of household education. Findings: The overall prevalence of excess weight among preschool children was 8% but varied substantially between and within countries, ranging from 4% to 25%. Our analysis showed that 97% of the variability was between individuals within sub-city units and around 3% of the variance in z-scores of weight for height was explained by the city and sub-city levels. At the city-level, a higher distance between urban patches (isolation, per 1 SD increase) was associated with lower odds of excess weight (OR 0.90, 95% CI 0.82-0.99). Higher sub-city education was also associated with lower odds of excess weight, but better sub-city living conditions were associated with higher odds of excess weight. Interpretation: Built and social environment features are related to excess weight in preschool children. Our evidence from a wide range of large Latin American cities suggests that urban health interventions may be suitable alternatives towards attaining the goal of reducing excess weight early in the life course.

RESUMO

As características físicas do ambiente podem contribuir na promoção da saúde, principalmente a disponibilidade e qualidade dos espaços públicos de lazer. O presente estudo tem como objetivo analisar a distribuição e a qualidade dos equipamentos para atividade física de lazer em uma capital brasileira. Foram avaliados 27 espaços públicos, incluindo parques, praças e canteiros habitáveis disponíveis no raio de 1.000 metros de três polos do Programa Academia da Saúde (PAS) no município de Belo Horizonte. Em 2019, os equipamentos foram auditados por meio da aplicação da versão adaptada do Physical Activity Resource Assessment (PARA), que avalia a existência, qualidade, segurança, limpeza e estética dos equipamentos. Frequências absolutas e relativas foram calculadas. Dos 27 locais avaliados, 22,2% eram parques (n = 6), 70,4% praças (n = 19) e 7,4% canteiros habitáveis (n = 2). Quadras de vôlei e campos de futebol foram os equipamentos mais identificados nos parques, presentes em todos os locais analisados, enquanto academias e estações de exercício ao ar livre foram os mais comuns nas praças (89,5%; 52,9%, respectivamente). Quanto aos canteiros habitáveis, apresentaram apenas quadras de vôlei/campos de futebol. Com relação à limpeza e estética, as maiores proporções foram pichações (74,1%), lixo espalhado/sujeira (74,1%), grama alta (44,4%) e sinais de vandalismo e sujeira de animais (37,0%). A pequena diversidade e qualidade ruim dos equipamentos, e as características inadequadas de limpeza e estética dos espaços de lazer no qual se encontram, podem impedir ou dificultar o uso dos mesmos para a prática de atividade física, demonstrando assim, a necessidade de investimentos mais expressivos nesses locais

The physical characteristics of the environment can contribute to health promotion, especially the availa-bility and quality of public leisure spaces. The present study aims to analyze the distribution and quality of equipment for leisure physical activity in a Brazilian capital. Twenty-seven public spaces, including parks, squares and boulevards available within a radius of 1,000 meters of three centers of the Health Academy Program (PAS) in the city of Belo Horizonte were evaluated. In 2019, the equipment was audited through the application of the adapted version of the Physical Activity Resource Assessment (PARA), which evaluates the existence, quality, safety, cleanliness, and aesthetics of the equipment. Absolute and relative frequencies were calculated. Of the 27 sites evaluated, 22.2% were parks (n=6), 70.4% were squares (n = 19), and 7.4% were boulevards (n = 2). Volleyball courts and soccer fields were the most identified equipment in parks, present in all analyzed places, while outdoor gyms and exercise stations were the most common in squares (89.5%; 52.9%, respectively). As for boulevards, they only had volleyball courts/soccer fields. Regarding cleanliness and aesthetics, the highest proportions were graffiti (74.1%), scattered garbage/dirt (74.1%), tall grass (44.4%), and signs of vandalism and animal dirt (37.0%). The small diversity and poor quality of equipment, and the inadequate characteristics of cleanliness and aesthetics of the leisure spaces in which they are located, can prevent or hinder their use for the practice of physical activity, thus demonstrating the need for more expressive investments in these places

RESUMO

Este artículo describe el proceso de diseño y las características de un cuestionario y una pauta de observación intradomiciliaria desarrollados para evaluar tanto transversal como longitudinalmente la relación vivienda-barrio-salud en el marco de transformaciones urbanas llevadas a cabo en poblaciones de elevada vulnerabilidad socio-territorial. Los instrumentos se desarrollaron para el estudio longitudinal multimétodos RUCAS (Regeneración Urbana, Calidad de Vida y Salud), un experimento natural cuyo objetivo principal es evaluar el impacto en salud y calidad de vida de un programa de Regeneración de Conjuntos Habitacionales en dos conjuntos de vivienda social en Chile. El diseño de los instrumentos siguió cuatro etapas principales: (1) revisión narrativa de la literatura para definir las dimensiones del estudio, y de instrumentos existentes para identificar ítems apropiados para su medición; (2) validación de contenido con expertos; (3) pre-test; y (4) estudio piloto. El cuestionario resultante, compuesto de 262 ítems, tiene en cuenta las distintas etapas del ciclo vital y cuestiones de género. La pauta de observación intradomiciliaria (77 ítems) es aplicada por el/la encuestadora. Los instrumentos abordan (i) características de la situación residencial actual que sabidamente afectan la salud y serán intervenidas por el programa; (ii) dimensiones de la salud potencialmente afectadas por la situación residencial y/o por la intervención dentro de los plazos del estudio (4 años); (iii) otras condiciones de salud y relacionadas con la salud que sean relevantes, aun cuando no se verán modificadas dentro de los plazos del estudio, y (iv) dimensiones socioeconómicas, ocupacionales y demográficas relevantes. Los instrumentos han mostrado ser una herramienta capaz de abordar la multidimensionalidad de los procesos de transformación urbana en contextos de pobreza urbana en vivienda formal.

This article describes the design and characteristics of a questionnaire and an intradomiciliary observation tool developed to assess the housing-neighborhood-health relationship both cross-sectionally and longitudinally in the context of urban transformations carried out in populations of high socio-territorial vulnerability. The instruments were developed for the multi-method longitudinal study RUCAS (Urban Regeneration, Quality of Life and Health), a natural experiment aiming to assess the quality of life and health impact of a comprehensive Urban Regeneration Program in two social housing complexes in Chile. The design of the instruments followed four main stages: (1) narrative review of the literature to define the dimensions of the study, and of existing measurement instruments to identify appropriate items for measuring them; (2) content validation with experts; (3) pre-test; and (4) pilot study. The resulting questionnaire, composed of 262 items, considers the different stages of the life course and gender issues. The intradomiciliary observation tool (77 items) is applied by the interviewer. The instruments assess (i) characteristics of the current residential situation that are known to affect health and will be intervened by the program; (ii) dimensions of health potentially affected by the residential situation and/or by the intervention within the time frame of the study (4 years); (iii) other health and health-related conditions that are relevant, even if changes will not be modified within the time frame of the study; and (iv) relevant socioeconomic, occupational and demographic dimensions. The instruments have shown to be capable of addressing the multidimensionality of urban transformation processes in contexts of urban poverty in formal housing.

RESUMO

Resumo: A desordem da vizinhança é um importante aspecto que pode impactar a saúde de residentes em áreas urbanas. Os objetivos desta pesquisa foram mapear e sistematizar os métodos de mensuração da desordem física e social na vizinhança em estudos realizados em cidades da América Latina. Por meio de revisão de escopo, foram mapeados artigos publicados a partir do ano 2000 em inglês, espanhol e português com os seguintes descritores: vizinhança, desordem física e desordem social. As buscas foram realizadas no MEDLINE (PubMed), LILACS (Biblioteca Virtual em Saúde), Scopus, Web of Science e Biblioteca Cochrane. Foram extraídas informações sobre autoria, ano, tipo de estudo, local, fonte de dados, população-alvo, desfecho, domínio, indicador, método, unidade geográfica e unidade de análise. As variáveis dos estudos relacionadas à desordem foram extraídas e agrupadas pela similaridade dos conteúdos e temas. Foram identificados 22 artigos, publicados entre 2012 e 2022, sendo a maioria do Brasil (n = 16). A percepção do indivíduo foi o método mais utilizado. O tema mais frequentemente abordado no domínio da desordem física foi vias públicas (n = 20), enquanto no domínio social foi segurança (n = 15). Detectou-se ausência de consenso na literatura quanto às variáveis utilizadas para aferir a desordem física e social da vizinhança em cidades da América Latina. Além da necessidade de padronização do tema, recomendam-se estudos que verifiquem a sustentabilidade de métodos de mensuração propostos, relevantes para classificar e comparar, de forma dinâmica, vizinhanças urbanas e os impactos na saúde com base nos níveis de exposição à desordem física e social.

Los objetivos fueron mapear y sistematizar los métodos de medición del desorden físico y social en el vecindario en estudios realizados en ciudades de América Latina. Por medio de una revisión de alcance, fueron mapeados artículos publicados a partir del año 2000 en inglés, español y portugués, que poseían los siguientes descriptores: vecindario, desorden físico y desorden social. Las búsquedas se realizaron en MEDLINE (PubMed), LILACS (Biblioteca Virtual en Salud), Scopus, Web of Science y Librería Cochrane. Se extrajeron informaciones sobre la autoría, el año, el tipo de estudio, la ubicación, la fuente de datos, la población objetivo, el resultado, el dominio, el indicador, el método, la unidad geográfica y la unidad de análisis. Las variables de los estudios relacionados con el desorden fueron extraídas y agrupadas por la similitud de los contenidos y temas. Fueron identificados 22 artículos, todos publicados entre 2012 y 2022, siendo la mayoría de Brasil (n = 16). La percepción del individuo fue el método más utilizado. El tema más frecuente abordado en el ámbito del desorden físico fue el de las vías públicas (n = 20) y seguridad (n = 15), en lo social. Se detectó una falta de consenso en la literatura en cuanto a las variables utilizadas para medir el desorden físico y social del vecindario en ciudades de América Latina. Además de la necesidad de estandarización del tema, se recomiendan estudios que verifiquen la sostenibilidad de los métodos de medición propuestos, relevantes para clasificar y comparar, de forma dinámica, los vecindarios urbanos y los impactos en la salud con base en niveles de exposición a desorden físico y social.

Abstract: Neighborhood disorder is an important aspect that may influence the health of residents in urban areas. The aims of this study were to map and systematize methods for measuring physical and social neighborhood disorder in studies conducted in Latin American cities. By means of a scoping review, articles published from 2000 in English, Spanish, and Portuguese with the following descriptors were mapped: neighborhood, physical disorder, and social disorder. Searches were conducted in MEDLINE (PubMed), LILACS (Virtual Health Library), Scopus, Web of Science, and Cochrane Library. Information on authorship, year, study type, locality, data source, target population, outcome, dominion, indicator, method, geographic unit, and unit of analysis was extracted. Variables from the disorder-related studies were extracted and grouped by similarity of content and themes. A total of 22 articles were identified, all published between 2012 and 2022, the majority in Brazil (n = 16). The perception of the individual was the most used method. The most frequent theme addressed in the physical disorder dominion was public streets (n = 20) and security (n = 15), in the social disorder dominion. A lack of consensus in the literature regarding variables used to measure physical and social neighborhood disorder in Latin American cities was detected. In addition to the need for standardization of the theme, studies to verify the sustainability of proposed measurement methods relevant to dynamically classify and compare urban neighborhoods and health impacts based on levels of exposure to physical and social disorder, are recommended.

RESUMO

Resumo A cidade é um modo de viver, pensar e sentir. O modo de vida urbano é capaz de produzir ideias, comportamentos, valores e conhecimentos, mas também pode acirrar disparidades socioeconômicas e de saúde da população que ali reside. Este artigo examina as disparidades em saúde urbana em seis capitais brasileiras: São Paulo, Rio de Janeiro, Salvador, Fortaleza, Belo Horizonte e Manaus. Para quantificar e mapear as disparidades intraurbanas nesses espaços, foram utilizados os dados do Censo Demográfico de 2010 para a aplicação do índice de saúde urbana (ISU), uma métrica que sintetiza oito diferentes variáveis socioeconômicas e de saneamento desagregadas por setores censitários. Os resultados são discutidos à luz de três vertentes teóricas: a diferenciação centro-periferia; abordagem econômica da saúde; e epidemiologia social. As descobertas desse estudo revelam que os setores censitários que abrangem populações com maior status socioeconômico e melhores condições de saneamento apresentaram índices de saúde urbana mais elevados do que os da periferia da cidade. Há indícios de melhores indicadores de saúde urbana para o Rio de Janeiro e São Paulo, em comparação com as demais capitais analisadas. No entanto, há importantes nuances em cada uma das seis cidades estudadas, especialmente quando se atribuem diferentes pesos às variáveis que compõem o ISU, apesar da marcada segregação espacial comum a todas elas. Considerar as distinções dentro do espaço urbano é uma estratégia fundamental para a compreensão desses aspectos sociais e econômicos e seus potenciais desdobramentos nas condições de saúde da população.

Abstract A city is a way of living, thinking, and feeling. The urban lifestyle can produce ideas, behaviors, values, and knowledge. Still, it can also intensify socioeconomic and health disparities in the population. This article examines urban health disparities in six Brazilian capitals: São Paulo, Rio de Janeiro, Salvador, Fortaleza, Belo Horizonte, and Manaus. To quantify and map intra-urban disparities in these spaces, data from the 2010 Demographic Census are used to apply the Urban Health Index, a metric that synthesizes eight different socio-economic and sanitation variables disaggregated by census tracts. The results are discussed in light of three theoretical perspectives: center-periphery differentiation, the economic approach to health, and social epidemiology. The findings of this study reveal that census tracts covering populations with higher socio-economic status and better sanitation conditions exhibited higher urban health index scores than those in the city's periphery. Results indicate better urban health indicators for Rio de Janeiro and São Paulo, compared to the other capitals analyzed. However, there are important nuances in each of the six cities, especially when assigning different weights to the variables that compose the Urban Health Index, despite the marked spatial segregation common to all. Considering distinctions within urban space is a fundamental strategy to understand these social and economic aspects and their potential implications for population health conditions.

Resumen La ciudad es una forma de vivir, pensar y sentir. El modo de vida urbano es capaz de producir ideas, comportamientos, valores y conocimientos, pero también lo es de intensificar las disparidades socioeconómicas y de salud de la población que reside en ella. Este artículo examina las disparidades en salud urbana en seis capitales brasileñas: São Paulo, Río de Janeiro, Salvador, Fortaleza, Belo Horizonte y Manaus. Para cuantificar y mapear las disparidades intraurbanas en estos espacios, se utilizan datos del censo demográfico de 2010 para aplicar el índice de salud urbana, una métrica que sintetiza ocho diferentes variables socioeconómicas y de saneamiento desagregadas por sectores censales. Los resultados se discuten a la luz de tres perspectivas teóricas: la diferenciación centro-periferia, el enfoque económico de la salud y la epidemiología social. Los hallazgos de este estudio revelan que los sectores censales que abarcan poblaciones con un mayor estatus socioeconómico y mejores condiciones de saneamiento presentaron puntajes más altos en el índice de salud urbana que los de la periferia de la ciudad. Hay indicios de mejores indicadores de salud urbana para Río de Janeiro y São Paulo, en comparación con las demás capitales analizadas. Sin embargo, se observan matices importantes en cada una de las seis ciudades analizadas, especialmente al asignar diferentes pesos a las variables que componen el pindice de salud urbana, a pesar de la marcada segregación espacial común a todas ellas. Considerar las distinciones dentro del espacio urbano es una estrategia fundamental para comprender estos aspectos sociales y económicos y sus posibles implicaciones en las condiciones de salud de la población.

RESUMO

Resumo O artigo propõe uma leitura crítica do contexto histórico urbanístico e social das comunidades de Manguinhos considerando a fundamentação teórico-metodológica do campo da saúde urbana, apoiada no paradigma da determinação social da saúde e do direito à cidade. O recorte de análise para a identificação dos processos críticos de determinação social da saúde considerou a relevância da superação das necessidades habitacionais como condição indispensável para o direito à cidade e à saúde. A constatação da permanência dos processos mencionados, mesmo após os vultosos investimentos em urbanização realizados em Manguinhos, aponta para a necessidade de revisão das políticas públicas relacionadas e a inserção efetiva e emancipatória da população nessas políticas.

Abstract This article proposes a critical reading of the urbanistic and social historical context of the communities of Manguinhos, considering the field of urban health as a theoretical and methodological foundation based on the paradigm of the social commitment to health and the right to the city. Our demarcation of this analysis to identify the critical processes in the social commitment to health considered the relevance of overcoming housing needs as an indispensable condition for the right to the city and to health. The fact that these processes persist, even after the vast investments made in Manguinhos, indicates the need to review related public policies and their effective implementation to improve conditions for this population.

RESUMO

BACKGROUND: Cardiovascular disease presents an increasing health burden to low- and middle-income countries. Although ample therapeutic options and care improvement frameworks exist to address its prime risk factor, hypertension, blood pressure control rates remain poor. We describe the results of an effectiveness study of a multisector urban population health initiative that targets hypertension in a real-world implementation setting in cities across three continents. The initiative followed the "CARDIO4Cities" approach (quality of Care, early Access, policy Reform, Data and digital technology, Intersectoral collaboration, and local Ownership). METHOD: The approach was applied in Ulaanbaatar in Mongolia, Dakar in Senegal, and São Paulo in Brazil. In each city, a portfolio of evidence-based practices was implemented, tailored to local priorities and available data. Outcomes were measured by extracting hypertension diagnosis, treatment and control rates from primary health records. Data from 18,997 patients with hypertension in primary health facilities were analyzed. RESULTS: Over one to two years of implementation, blood pressure control rates among enrolled patients receiving medication tripled in São Paulo (from 12·3% to 31·2%) and Dakar (from 6·7% to 19·4%) and increased six-fold in Ulaanbaatar (from 3·1% to 19·7%). CONCLUSIONS: This study provides first evidence that a multisectoral population health approach to implement known best-practices, supported by data and digital technologies, and relying on local buy-in and ownership, can improve hypertension control in high-burden urban primary care settings in low-and middle-income countries.

RESUMO

Exposure to non-optimal temperatures remains the single most deathful direct climate change impact to health. The risk varies based on the adaptation capacity of the exposed population which can be driven by climatic and/or non-climatic factors subject to fluctuations over time. We investigated temporal changes in the exposure-response relationship between daily mean temperature and mortality by cause of death, sex, age, and ethnicity in the megacity of São Paulo, Brazil (2000-2018). We fitted a quasi-Poisson regression model with time-varying distributed-lag non-linear model (tv-DLNM) to obtain annual estimates. We used two indicators of adaptation: trends in the annual minimum mortality temperature (MMT), i.e., temperature at which the mortality rate is the lowest, and in the cumulative relative risk (cRR) associated with extreme cold and heat. Finally, we evaluated their association with annual mean temperature and annual extreme cold and heat, respectively to assess the role of climatic and non-climatic drivers. In total, we investigated 4,471,000 deaths from non-external causes. We found significant temporal trends for both the MMT and cRR indicators. The former was decoupled from changes in AMT, whereas the latter showed some degree of alignment with extreme heat and cold, suggesting the role of both climatic and non-climatic adaptation drivers. Finally, changes in MMT and cRR varied substantially by sex, age, and ethnicity, exposing disparities in the adaptation capacity of these population groups. Our findings support the need for group-specific interventions and regular monitoring of the health risk to non-optimal temperatures to inform urban public health policies.

RESUMO

There is limited empirical evidence on how travel time affects dietary patterns, and even less in Latin American cities (LACs). Using data from 181 LACs, we investigated whether longer travel times at the city level are associated with lower consumption of vegetables and higher consumption of sugar-sweetened beverages and if this association differs by city size. Travel time was measured as the average city-level travel time during peak hours and city-level travel delay time was measured as the average increase in travel time due to congestion on the street network during peak hours. Vegetables and sugar-sweetened beverages consumption were classified according to the frequency of consumption in days/week (5-7: "frequent", 2-4: "medium", and ≤1: "rare"). We estimate multilevel ordinal logistic regression modeling for pooled samples and stratified by city size. Higher travel time (Odds Ratio (OR) = 0.65; 95% Confidence Interval (CI) 0.49-0.87) and delay time (OR = 0.57; CI 0.34-0.97) were associated with lower odds of frequent vegetable consumption. For a rare SSB consumption, we observed an inverse association with the delay time (OR = 0.65; CI 0.44-0.97). Analysis stratified by city size show that these associations were significant only in larger cities. Our results suggest that travel time and travel delay can be potential urban determinants of food consumption.

RESUMO

BACKGROUND: Understanding how urban environments influence people's health, especially as individuals age, can help identify ways to improve health in the rapidly urbanizing and rapidly aging populations. OBJECTIVES: To investigate the association between age and self-reported health (SRH) in adults living in Latin-American cities and whether gender and city-level socioeconomic characteristics modify this association. METHODS: Cross-sectional analyses of 71,541 adults aged 25-97 years, from 114 cities in 6 countries (Argentina, Brazil, Colombia, Chile, El Salvador, and Guatemala), as part of the Salud Urbana en America Latina (SALURBAL) Project. We used individual-level age, gender, education, and self-reported health (SRH) data from harmonized health surveys. As proxies for socioeconomic environment we used a city-level socioeconomic index (SEI) calculated from census data, and gross domestic product (GDP) per-capita. Multilevel Poisson models with a robust variance were used to estimate relative risks (RR), with individuals nested in cities and binary SRH (poor SHR vs. good SRH) as the outcome. We examined effect modification by gender and city-level socioeconomic indicators. RESULTS: Overall, 31.4% of the sample reported poor SRH. After adjusting for individual-level education, men had a lower risk of poor SRH (RR = 0.76; CI 0.73-0.78) compared to women, and gender modified the association between age and poor SRH (p-value of interaction < 0.001). In gender stratified models, the association between older age and poor SRH was more pronounced in men than in women, and in those aged 25-65 than among those 65+ (RR/10 years = 1.38 vs. 1.10 for men, and RR/10 years = 1.29 vs. 1.02 for women). Living in cities with higher SEI or higher GDP per-capita was associated with a lower risk of poor SRH. GDP per-capita modified the association between age (25-65) and SRH in men and women, with SEI the interaction was less clear. CONCLUSIONS: Across cities in Latin America, aging impact on health is significant among middle-aged adults, and among men. In both genders, cities with lower SEI or lower GDP per-capita were associated with poor SRH. More research is needed to better understand gender inequalities and how city socioeconomic environments, represented by different indicators, modify exposures and vulnerabilities associated with aging.

RESUMO

Globally, the question of how to improve the living standards of the inhabitants of informal settlements is a key political concern. These neighborhoods are characterized by economic vulnerability, social marginalization, and inaccessibility of basic services. The aim of this study is to provide evidence about the environmental risk factors faced by these populations in Argentina, and to identify whether their greater exposure to risk factors is associated with greater accessibility of healthcare services. We analyzed an original database that provides information about basic characteristics of the neighborhood, environmental risk factors (proximity to garbage dumps, industrial waste, and high-voltage towers), and accessibility of basic healthcare services on over 2000 informal settlements in Argentina. We calculated descriptive statistics and developed multivariate econometric models to estimate the probability of accessibility of healthcare services. On average, 31% of informal settlements were close to a garbage dump, 19% were close to a high-voltage tower, and 10% were close to industrial waste. In addition, 39% of these neighborhoods do not have a healthcare center nearby, 65% do not have an accessible hospital, and 39% are not consistently served by ambulances in the event of an emergency. The econometric estimates suggest that the accessibility of hospital healthcare service and to an ambulance service is positively associated with the age of the neighborhood, and whether the neighborhood is a slum, but there is no evidence of association with the exposure to environmental risk factors. In short, the populations living in informal settlements in Argentina are exposed to harmful environmental risk factors. Access to basic healthcare services is limited and does not reflect the elevated exposure to environmental risks. Health, environmental, and economic dimensions should be considered when designing and implementing public policies for vulnerable populations.

RESUMO

BACKGROUND: In the global debate around transactional sex little attention has concentrated on Brazil, despite ranking fourth globally in absolute number of girls married or co-habiting by the age of 15 years, and evidence showing that these unions often begin as age-disparate transactional sex (ADTS). This article contributes to filling this gap by exploring the personal beliefs and social norms related to ADTS in urban (favela) communities of Rio de Janeiro, Brazil between adult men (> 18 years) and girls and adolescents (G/A) (< 18 years) with a minimum 5-year age disparity. The primary objective of this study was to identify the social norms that promote and prevent ADTS, and the dynamics between individual beliefs and social norms, to provide contextualized recommendations to prevent ADTS in this setting. METHODS: An exploratory, sequential, mixed-methods design was used, starting with a qualitative phase that included semi-structured, in-depth interviews and focus groups, and a subsequent quantitative phase comprising of a community survey. The items for the quantitative questionnaires were developed based on the qualitative results. RESULTS: Mixed methods results indicate that in these communities ADTS is normalised and not considered exploitative. We identified three themes related to the reasons ADTS occurs: girls' responsibility, male desires and benefits of ADTS. Men's role in ADTS was largely minimised because of a general acceptance of a notion of masculinity characterised by hypersexuality and lack of impulse control. Individual beliefs, however, did not tend to align with these social norms. CONCLUSIONS: In this study, personal beliefs and social norms often did not align, suggesting that initiatives working to change personal or attitudes regarding ADTS may not lead to meaningful change in ADTS behaviours, and social norms interventions may be more effective. Our findings reinforce the need to develop programs tailored to local understandings of ADTS, targeting not only girls but also a wide range of actors. Interventions could also consider the structural factors acting in local and global contexts that promote or prevent ADTS.

This article explores the personal beliefs and social norms related to the exchange of sexual favours or relationships for material favours, gifts and/or support in some form, between adult men (> 18 years) and girls and adolescents (< 18 years) with a minimum 5-year age difference. We used interviews, focus groups and questionnaires to understand the factors that promote and prevent these sexual relationships between men and girls. Motivators for these relationships were often related to girls' responsibilities, male desires and the benefits of these relationships. Men's responsibility for their participation in these relationships with girls were often minimised due to a general acceptance of men as overly sexual and lacking impulse control. In this study, personal beliefs and social norms were often not aligned, suggesting that interventions focused on changing personal beliefs or attitudes about these sexual relationships may not be enough to change social norms. The findings highlight the need to develop solutions that consider a wider range of actors, instead of interventions focused only on girls. The study findings also support the need to further investigate how communities and shared expectations can influence sexual relationships in exchange for goods between adult men and girls and adolescents.

RESUMO

We estimated excess mortality in Chilean cities during the COVID-19 pandemic and its association with city-level factors. We used mortality, and social and built environment data from the SALURBAL study for 21 Chilean cities, composed of 81 municipalities or "comunas", grouped in 4 macroregions. We estimated excess mortality by comparing deaths from January 2020 up to June 2021 vs 2016-2019, using a generalized additive model. We estimated a total of 21,699 (95%CI 21,693 to 21,704) excess deaths across the 21 cities. Overall relative excess mortality was highest in the Metropolitan (Santiago) and the North regions (28.9% and 22.2%, respectively), followed by the South and Center regions (17.6% and 14.1%). At the city-level, the highest relative excess mortality was found in the Northern cities of Calama and Iquique (around 40%). Cities with higher residential overcrowding had higher excess mortality. In Santiago, capital of Chile, municipalities with higher educational attainment had lower relative excess mortality. These results provide insight into the heterogeneous impact of COVID-19 in Chile, which has served as a magnifier of preexisting urban health inequalities, exhibiting different impacts between and within cities. Delving into these findings could help prioritize strategies addressed to prevent deaths in more vulnerable communities.
