Are Neighborhood Greenspaces Associated with Leisure-time Physical Activity? Results from ELSA-Brasil Eight-year Follow-up.

We investigated whether neighborhood greenspaces were associated with physical activity in adulthood over 3 cohort visits after considering perceived safety and neighborhood contextual factors. We also evaluated whether the association with greenspace varied by neighborhood socioeconomic status. Participants (N = 4,800) from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) residing in two Brazilian state capitals were evaluated in Visits 1 (2008-2010), 2 (2012-2014) and 3 (2017-2019). Greenspaces were categorized by quintiles of positive Normalized Difference Vegetation Index (NDVI) scores. Physical activity frequency was given by the number of visits at which participants reported moderate/vigorous physical activity (none, 1 or 2, and 3 visits). We used multinomial logistic regression. After adjustment for age, sex, education, research center, residence in slums, individuals in the 4th and 5th NDVI quintiles showed 73% higher odds of physical activity over 3 visits than those in the 1st quintile (4th quintile: 95%CI = 1.24-2.43; 5th quintile: 95%CI = 1.24-2.41). The strength of the association was attenuated after adjustment for perceived safety. After adjustment for contextual factors quantity of sidewalks and streetlights, the OR for the 4th and 5th NDVI quintiles decreased to 1.66 (95%CI = 1.18-2.33) and 1.62 (95%CI = 1.16-2.28), respectively. Finally, after including average household income per capita, the OR for physical activity in 3 visits for the 4th and 5th NDVI quintiles decreased to 1.48 (95%CI = 1.04-2.12) and 1.43 (95%CI = 1.00-2.04; p = 0.053), respectively. Greater greenspace contributed to sustained physical activity during the eight years of follow-up, indicating the potential contribution of public greenspaces to reducing health-related inequalities.

Associations of Household and Neighborhood Contexts and Hair Cortisol Among Mexican-Origin Adolescents From Low-Income Immigrant Families.

Although neighborhood contexts serve as upstream determinants of health, it remains unclear how these contexts "get under the skin" of Mexican-origin youth, who are disproportionately concentrated in highly disadvantaged yet co-ethnic neighborhoods. The current study examines the associations between household and neighborhood socioeconomic status (SES), neighborhood racial-ethnic and immigrant composition, and hair cortisol concentration (HCC)-a physiological index of chronic stress response-among Mexican-origin adolescents from low-income immigrant families in the United States. A total of 297 (54.20% female; mage = 17.61, SD = 0.93) Mexican-origin adolescents had their hair cortisol collected, and their residential addresses were geocoded and merged with the American Community Survey. Neighborhoods with higher Hispanic-origin and foreign-born residents were associated with higher neighborhood disadvantage, whereas neighborhoods with higher non-Hispanic White and domestic-born residents were associated with higher neighborhood affluence. Mexican-origin adolescents living in neighborhoods with a higher proportion of Hispanic-origin residents showed lower levels of HCC, consistent with the role of the ethnic enclave. In contrast, adolescents living in more affluent neighborhoods showed higher levels of HCC, possibly reflecting a physiological toll. No association was found between household SES and HCC. Our findings underscore the importance of taking sociocultural contexts and person-environment fit into consideration when understanding how neighborhoods influence adolescents' stress physiology.

The Association of Neighborhood Socioeconomic Status with Executive Function and Processing Speed in Cognitively Normal Mexican American Elders from the Health and Aging Brains Study: Health Disparities Cohort.

INTRODUCTION: Neighborhood socioeconomic status (NSES) has been linked with overall health, and this study will evaluate whether NSES is cross-sectionally associated with cognition in non-Hispanic whites (NHWs) and Mexican Americans (MAs) from the Health and Aging Brain: Health Disparities Study (HABS-HD). METHODS: The HABS-HD is a longitudinal study conducted at the University of North Texas Health Science Center. The final sample analyzed (n = 1,312) were 50 years or older, with unimpaired cognition, and underwent an interview, neuropsychological examination, imaging, and blood draw. NSES was measured using the national area deprivation index (ADI) percentile ranking, which considered socioeconomic variables. Executive function and processing speed were assessed by the trail making tests (A and B) and the digit-symbol substitution test, respectively. Linear regression was used to assess the association of ADI and cognitive measures. RESULTS: MAs were younger, more likely to be female, less educated, had higher ADI scores, performed worse on trails B (all p < 0.05), and had lower prevalence of APOE4 + when compared to NHWs (p < 0.0001). A higher percentage of MAs lived in the most deprived neighborhoods than NHWs. For NHWs, ADI did not predict trails B or DSS scores, after adjusting for demographic variables and APOE4. For MAs, ADI predicted trails A, trails B, and DSS after adjusting for demographic covariates and APOE4 status. CONCLUSION: Our study revealed that living in an area of higher deprivation was associated with lower cognitive function in MAs but not in NHWs, which is important to consider in future interventions to slow cognitive decline.

Perceived Neighbourhood Disorder, Alcohol Consumption and Alcohol-Related Problems in Chile.

Background: Alcohol misuse is one of the most important preventable public health risk factors. Empirical research shows that alcohol misuse is related to social and economic losses. Both theoretical and empirical evidence suggests that neighborhood disorder impacts alcohol-related behavior. However, there is limited literature in the context of developing countries. Objectives: The aim of this research is to estimate the association between perceived neighborhood disorder and (1) alcohol-related behavior and (2) alcohol-related problems in the context of the Chilean population. Our contribution focuses on the examination of the perception of disorder in urban neighborhoods and alcohol use patterns in a wide age range and sample of Chilean cities. Results: High levels of neighbor disorder perception are associated with higher levels of drinking and hazardous alcohol use. In addition, perceived neighborhood disorder is directly associated with probability of alcohol-related problems (ranging from 2% to 11%). Conclusions/Importance: The results are consistent with empirical and theoretical frameworks. This research could be used to better guide place-based policies in emerging countries with high levels of alcohol consumption to prevent alcohol risk behaviors and alcohol-related problems.

Social determinants of health and metabolic syndrome in Colombian older adults.

BACKGROUND AND AIMS: Social determinants of health (SDH) are critical in health outcomes. More insight is needed on the correlation between SDH and metabolic syndrome (MetS) in the aging population. This study assessed the association between SDH and MetS scores among older adults in Colombia. METHODS AND RESULTS: This cross-sectional country-wide study includes a sample of 4085 adults aged ≥60 from the SABE Colombia Survey. MetS measurements were central obesity, hyperglycemia or diabetes, hypertriglyceridemia, arterial hypertension, and low HDL cholesterol (MetS score 0-5). SDH includes four levels: 1- general socioeconomic and environmental conditions; 2-social and community networks; 3- individual lifestyle; and 4-constitutional factors. In multivariate linear regression analysis, the SDH factors with greater effect sizes, calculated by Eta Squared, predicting higher MetS mean scores were women followed by low education, no alcohol intake, urban origin, and residing in unsafe neighborhoods. Two interactions: men, but not women, have lower MetS in safe neighborhoods compared to unsafe, and men, but not women, have lower MetS when having low education (0-5 years) compared to high (≥6). CONCLUSION: Gender, education, alcohol intake, and origin have the greatest effect sizes on MetS. Education level and neighborhood safety modified the relationship between gender and MetS. Low-educated men or those residing in safe neighborhoods have lower MetS. Neighborhood environments and educational differences influencing MetS should be considered in future studies.

Association between self-perception of the neighborhood environment and sleep problems in older Brazilian adults: findings from ELSI-Brazil / Associação entre autopercepção do ambiente da vizinhança e problemas de sono em idosos brasileiros: resultados do ELSI-Brasil / Asociación entre la autopercepción del entorno del vecindario y los problemas de sueño en ancianos brasileños: resultados del ELSI-Brasil

Abstract: This study aimed to investigate associations between neighborhood perception and sleep problems in older Brazilian adults. A cross-sectional study was conducted with 5,719 community-dwelling older adults (≥ 60 years) from the Brazilian Longitudinal Study of Aging (ELSI-Brazil, 2019-2021). The outcomes were self-reported sleep problems: poor sleep quality, daytime sleepiness, primary insomnia complaints, difficulty staying asleep, and waking up at dawn. The exposure variables were questions about the perception of participants about the physical and social environment of the neighborhood. Logistic regression was used in data analysis. Garbage, rubbish, or tall grass on the streets and the desire to move were associated with higher odds of poor sleep quality. Concern about falling due to damaged sidewalks, concern about having difficulties taking transportation, and concern about having difficulties crossing the street were associated with higher odds of all sleep problems. Sound/noise of buses and cars was associated with higher odds of some sleep problems. Perceiving the neighborhood as a good place to live was associated with lower odds of daytime sleepiness and primary insomnia complaints. Trusting most people in the neighborhood and perceiving that kids and younger people treat adults with respect were associated with lower odds of daytime sleepiness, primary insomnia complaints, and waking up at dawn. Being a good place for kids to play and raise teenagers was associated with lower odds of daytime sleepiness. These results can assist public administrators in creating urban planning policies aimed at improving neighborhood environments as a means of health promotion.

Foi realizado um estudo transversal com 5.719 idosos da comunidade (≥ 60 anos) do Estudo Longitudinal da Saúde dos Idosos Brasileiros (ELSI-Brasil, 2019-2021). Os desfechos foram problemas de sono autorreferidos: má qualidade do sono, sonolência diurna, queixas de insônia primária, dificuldade em manter o sono e acordar na madrugada. As variáveis de exposição foram: questões sobre a percepção dos participantes sobre o ambiente físico e social da vizinhança. Regressão logística foi utilizada na análise dos dados. Lixo, sujeira ou grama alta nas ruas e o desejo de mudar de onde mora foram associados a maiores chances de má qualidade do sono. Preocupação em cair devido a calçadas em má condição, preocupação com dificuldades para usar os meios de transporte e preocupação com dificuldades para atravessar a rua foram associadas a maiores chances de todos os problemas de sono. O som/ruído dos ônibus e carros foi associado a maiores chances de alguns problemas de sono. A percepção da vizinhança como um bom lugar para morar foi associado a menores chances de sonolência diurna e queixas de insônia primária. A confiança na maioria das pessoas da vizinhança e a percepção de que crianças e jovens tratam os adultos com respeito foram associados a menores chances de sonolência diurna, queixas de insônia primária e acordar na madrugada. Um bom lugar para as crianças brincarem e para os adolescentes crescerem foi associado a menores chances de sonolência diurna. Esses resultados podem ajudar os gestores públicos na criação de políticas de planejamento urbano voltadas a melhorias nos ambientes da vizinhança como forma de promoção da saúde.

La preocupación por las caídas debido a aceras en mal estado, la preocupación por las dificultades para utilizar los medios de transporte y la preocupación por las dificultades para cruzar la calle se asociaron con mayores probabilidades de sufrir todos los problemas de sueño. El ruido producido por los autobuses y automóviles se asoció con una mayor probabilidad de sufrir algunos problemas de sueño. La percepción del vecindario como un buen lugar para vivir se asoció con menores probabilidades de sufrir somnolencia diurna y quejas de insomnio primario. La confianza en la mayoría de la gente del vecindario y la percepción de que los niños y jóvenes tratan a los adultos con respeto se asociaron con menores probabilidades de sufrir somnolencia diurna, quejas de insomnio primario y despertarse durante la madrugada. Un buen lugar para que los niños jugaran y para que los adolescentes crecieran se asoció con menores probabilidades de sufrir somnolencia diurna. Estos resultados pueden ayudar a los gestores públicos a crear políticas de planificación urbana dirigidas a mejorar los entornos vecinales como forma de promover la salud.

A segregação residencial socioeconômica está associada aos problemas do sono? Insights do ELSA-Brasil / Is socioeconomic residential segregation associated with sleep problems? Insights from ELSA-Brasil / ¿Está asociada la segregación residencial socioeconómica con problemas de sueño? Insights de ELSA-Brasil

Resumo: O sono é influenciado por diversos fatores e é essencial para a saúde. O papel do contexto socioeconômico da vizinhança na saúde do sono foi estudado nos últimos anos, mas os resultados são inconsistentes. O objetivo deste estudo foi investigar a associação entre a segregação residencial socioeconômica e os problemas do sono. Utilizou-se dados da 2ª avaliação (2012-2014) de 9.918 servidores públicos participantes do Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil). A segregação residencial socioeconômica foi avaliada por meio da estatística Getis-Ord Local Gi*, e a duração e privação do sono, as queixas de insônia e a sonolência diurna foram obtidas por meio de entrevistas. Para as estimativas da odds ratio (OR), foram utilizados modelos de regressão logística binomial e multinomial. Em relação ao sono, 49% tinham curta duração e 3% longa duração, 23% relataram queixas de insônia, 45% relataram privação do sono, 42% relataram sonolência diurna e 48% relataram ≥ 2 problemas do sono. No modelo ajustado por variáveis demográficas e socioeconômicas, houve associação entre alta segregação residencial socioeconômica e duração curta do sono (OR = 1,22; IC95%: 1,07; 1,40), privação do sono (OR = 1,20; IC95%: 1,05; 1,37), sonolência diurna (OR = 1,17; IC95%: 1,03; 1,34) e ≥ 2 problemas associados do sono (OR = 1,24; IC95%: 1,08; 1,41). Indivíduos que vivem em vizinhanças com alta segregação residencial socioeconômica apresentam maior chance de terem curta duração, privação do sono, sonolência diurna e ≥ 2 problemas associados ao sono. Essas informações reforçam que políticas públicas para reduzir as desigualdades socioeconômicas podem contribuir para melhorar a saúde do sono da população.

Abstract: Several factors influence sleep, which is essential for health. While the role of neighborhood socioeconomic context on sleep health has been studied in recent years, results are inconsistent. The study aimed to investigate the association between socioeconomic residential segregation and sleep problems, using data from the second evaluation (2012-2014) of 9,918 public servants participating in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Socioeconomic residential segregation was assessed using the Getis-Ord Local Gi* statistic. Sleep duration and deprivation, complaints of insomnia, and daytime sleepiness were obtained through interviews. Binomial and multinomial logistic regression models were used to estimate the odds ratio (OR). Regarding sleep, 49% had short duration and 3% long duration, 23% reported complaints of insomnia, 45% sleep deprivation, 42% daytime sleepiness, and 48% reported ≥ 2 sleep problems. In the model adjusted for demographic and socioeconomic variables, there was an association between high socioeconomic residential segregation and short sleep duration (OR = 1.22; 95%CI: 1.07; 1.40), sleep deprivation (OR = 1.20; 95%CI: 1.05; 1.37), daytime sleepiness (OR = 1.17; 95%CI: 1.03; 1.34) and ≥ 2 associated sleep problems (OR = 1.24; 95%CI: 1.08; 1.41). Individuals living in neighborhoods with high socioeconomic residential segregation are more likely to have short sleep duration, sleep deprivation, daytime sleepiness, and ≥ 2 associated sleep problems. This information reinforces that public policy measures to reduce socioeconomic inequalities can improve the population's sleep health.

Mexican-origin parent and child reported neighborhood factors and youth substance use.

Background: Structural oppression affects health behaviors through residence in suboptimal neighborhoods and exposure to community violence. Youth and parents report perceptions of neighborhood factors that can affect youth substance use behaviors. Given that Latinx youth report higher levels of perceived community violence than other racial and ethnic groups, it is imperative to examine how youth- and parent-perceived neighborhood-level factors may relate to youth substance use. Methods: Data were collected using clinical interviews with family triads (fathers, mothers, and youth) and parent-child dyads (father or mother and youth) enrolled in the Seguimos Avanzando study of 344 Mexican-origin families in Indiana. Neighborhood measures, including perceptions of exposure to violence, neighborhood characteristics, and neighborhood collective efficacy, were included in parent and youth surveys. Self-report measures for past year alcohol and drug use were included in the youth survey only. T-tests were conducted to estimate differences in neighborhood reports among the sample triads. A series of linear regression models were used to estimate the associations between youth-, mother-, and father-reported perceptions of neighborhood factors and youth substance use. Results: Preliminary results indicate that fathers reported higher levels of exposure to violence than mothers [t(163) = 2.33, p = 0.02] and youth [t(173) = 3.61, p < 0.001]. Youth reported lower negative neighborhood characteristics than mothers [t(329) = 6.43, p < 0.001] and fathers [t(169) = 3.73, p < 0.001]. Youth reported significantly better neighborhood collective efficacy than mothers [t(296) = 3.14, p = 0.002], but not statistically different from fathers. Results from the primary analysis showed that youth exposure to violence was positively associated with youth substance use (b = 0.24, SE = 0.06, p < 0.0001), but the youth's neighborhood characteristics and collective efficacy were not significantly associated with youth substance use. None of the parent-reported neighborhood variables were associated with youth substance use. Conclusion: The discrepant findings between parent and youth reports of perceived neighborhood characteristics and substance use have important implications for researchers and community stakeholders, and for developing targeted interventions and prevention strategies. Our study highlights the need to address youth experience of community violence and to prioritize creating safe and inclusive neighborhood environments. Potential strategies include improving community resources, strengthening social support networks, promoting open communication about neighborhood risks, and fostering collaborative efforts to address substance use behaviors.

Abundance of Non-Native Birds in the City: Spatial Variation and Relationship with Socioeconomics in a South American City.

Cities commonly support a high abundance of non-native species that can affect both wildlife and human health; however, their distribution across the urban environment and their relationship with socioeconomics are not well documented. Here, we map the abundance of three non-native birds in a Latin American city-domestic pigeon (Columba livia f. domestica), house sparrow (Passer domesticus), and monk parakeet (Myiopsitta monachus)-and investigate the effect of socioeconomics on their abundance. We found that C. livia f. domestica exhibited a random distribution of abundance across the city but reached its greatest abundance in low-income areas. P. domesticus exhibited an aggregated distribution of abundance, being most abundant in the southern and western areas of the city and in low-income areas. M. monachus exhibited an aggregated distribution of abundance, being most abundant in the northeastern part of the city and reaching its greatest abundance in high-income areas. Low-income areas likely provide high abundance of food, shelter, and nesting sites for both C. livia f. domestica and P. domesticus, whereas high income areas have greater tree cover and larger trees in which M. monachus can build communal nests. Our study finds that the abundance of non-native birds varies across the city and between socioeconomic groups; therefore, targeted management is needed in different city zones to limit negative effects on native species and prevent zoonotic diseases.

Discrimination and Depressive Symptoms Among Mexican American Women: Exploring Multilevel Sociocultural Moderators.

Relative to empirical studies on risk factors, less research has focused on culturally based protective factors that reduce the impact of discrimination on mental health. The current prospective study evaluated two potential moderators of the effect of discrimination on depressive symptoms among Mexican American women: individually held familism values and neighborhood cultural cohesion. Mexican-origin women in the United States (N = 322; mean age = 27.8 years; 86% born in Mexico) reported on frequency of discrimination, depressive symptoms, familism, and neighborhood cultural cohesion. Independent models evaluated familism and neighborhood cultural cohesion as moderators of the effect of discrimination on subsequent depressive symptoms. More frequent discrimination predicted higher subsequent depressive symptoms. High familism buffered the harmful effect of discrimination on depressive symptoms, such that more frequent discrimination was associated with higher subsequent depressive symptoms only for women who reported average and low familism. Neighborhood cultural cohesion did not buffer the effect of discrimination on depressive symptoms.

Urban distance to mental healthcare units and public transport increases duration of untreated psychosis in first-episode patients.

BACKGROUND: There is a growing interest in environmental and social determinants of mental health. However, how distance to healthcare and public transportation affect illness is neglected in schizophrenia research. Here, we are interested in how the availability of mental healthcare and the ways to reach it may be associated with psychosis. AIMS: We aim to investigate the association between distances to healthcare units and subway stations and duration of untreated psychosis (DUP) and greater initial severity in an antipsychotic-naïve first episode of psychosis (FEP) sample. METHOD: Using 212 untreated FEP patients' data, we calculated the distances from their residences to the places of interest. Diagnoses comprehended schizophrenia spectrum disorders, depressive and bipolar affective disorders, and substance-induced disorders. Linear regressions were performed with distances as independent variables, DUP and Positive and Negative Syndrome Scale (PANSS) scores as dependent variables. RESULTS: Longer distance to emergency mental healthcare was related to longer DUP (95% CI: p = .034, B = 0.152) and higher total PANSS (95% CI: p = .007, B = 0.0189); longer distance to community mental healthcare units was related to longer DUP (95% CI: p = .004, B = 0.0204) and higher total PANSS (95% CI: p = .030, B = 0.152). Moreover, a longer distance to the closest subway station predicted longer DUP (95% CI: p = .019, B = 0.170). CONCLUSION: Our results indicate that poor healthcare access is related to longer DUP and higher initial PANSS scores. Future research should investigate how investments in mental health access and actions to improve public transport access could impact DUP and treatment outcomes in psychosis patients.

Family and Neighborhood Resilience Are Associated with Children's Healthcare Utilization.

OBJECTIVE: To evaluate the association of external factors of resilience, neighborhood, and family resilience with healthcare use. STUDY DESIGN: A cross-sectional, observational study was conducted using data from the 2016-2017 National Survey of Children's Health. Children aged 4-17 years were included. Multiple logistic regression was used to determine aOR and 95% CIs for association between levels of family resilience, neighborhood resilience and outcome measures: presence of medical home, and ≥2 emergency department (ED) visits per year while adjusting for adverse childhood experiences (ACEs), chronic conditions, and sociodemographic factors. RESULTS: We included 58 336 children aged 4-17 years, representing a population of 57 688 434. Overall, 8.0%, 13.1%, and 78.9% lived in families with low, moderate, and high resilience, respectively; 56.1% identified their neighborhood as resilient. Of these children, 47.5% had a medical home and 4.2% reported ≥2 ED visits in the past year. A child with high family resilience had 60% increased odds of having a medical home (OR, 1.60; 95% CI, 1.37-1.87), and a child with moderate family resilience or resilient neighborhood had a 30% increase (OR, 1.32 [95% CI, 1.10-1.59] and OR, 1.31 [95% CI, 1.20-1.43], respectively). There was no association between resilience factors and ED use, although children with increased ACEs had increased ED use. CONCLUSIONS: Children from resilient families and neighborhoods have an increased odds of receiving care in a medical home after adjusting for the effects of ACEs, chronic conditions, and sociodemographic factors, but no association was seen with ED use.

The neighborhood context and all-cause mortality among older adults in Puerto Rico.

Background: Recent efforts have been made to collect data on neighborhood-level attributes and link them to longitudinal population-based surveys. These linked data have allowed researchers to assess the influence of neighborhood characteristics on the health of older adults in the US. However, these data exclude Puerto Rico. Because of significantly differing historical and political contexts, and widely ranging structural factors between the island and the mainland, it may not be appropriate to apply current knowledge on neighborhood health effects based on studies conducted in the US to Puerto Rico. Thus, we aim to (1) examine the types of neighborhood environments older Puerto Rican adults reside in and (2) explore the association between neighborhood environments and all-cause mortality. Methods: We linked data from the 2000 US Census to the longitudinal Puerto Rican Elderly Health Conditions Project (PREHCO) with mortality follow-up through 2021 to examine the effects of the baseline neighborhood environment on all-cause mortality among 3,469 participants. Latent profile analysis, a model-based clustering technique, classified Puerto Rican neighborhoods based on 19 census block group indicators related to the neighborhood constructs of socioeconomic status, household composition, minority status, and housing and transportation. The associations between the latent classes and all-cause mortality were assessed using multilevel mixed-effects parametric survival models with a Weibull distribution. Results: A five-class model was fit on 2,477 census block groups in Puerto Rico with varying patterns of social (dis)advantage. Our results show that older adults residing in neighborhoods classified as Urban High Deprivation and Urban High-Moderate Deprivation in Puerto Rico were at higher risk of death over the 19-year study period relative to the Urban Low Deprivation cluster, controlling for individual-level covariates. Conclusions: Considering Puerto Rico's socio-structural reality, we recommend that policymakers, healthcare providers, and leaders across industries to (1) understand how individual health and mortality is embedded within larger social, cultural, structural, and historical contexts, and (2) make concerted efforts to reach out to residents living in disadvantaged community contexts to understand better what they need to successfully age in place in Puerto Rico.

Optimizing Resources and Increasing the Coverage of Internet-of-Things (IoT) Networks: An Approach Based on LoRaWAN.

A resource optimization methodology is proposed for application in long range wide area networks (LoRaWANs). Using variable neighborhood search (VNS) and a minimum-cost spanning tree algorithm, it reduces the implementation and the maintenance costs of such low power networks. Performance evaluations were conducted in LoRaWANs with LoRa repeaters to increase coverage, in scenario where the number and the location of the repeaters are determined by the VNS metaheuristic. Parameters such as spread factor (SF), bandwidth and transmission power were adjusted to minimize the network's total energy per useful bit (Ebit) and the total data collection time. The importance of the SF in the trade-off between (Ebit) and time on-air is evaluated, considering a device scaling factor. Simulation results, obtained after model adjustments with experimental data, show that, in networks with few associated devices, there is a preference for small values of SF aiming at reduction of Ebit. The usage of large SF's becomes relevant when reach extensions are required. The results also demonstrate that, for networks with high number of nodes, the scaling of devices over time become relevant in the fitness function, forcing an equal distribution of time slots per SF to avoid discrepancies in the time data collection.

Ecological study of the association between socioeconomic inequality and food deserts and swamps around schools in Rio de Janeiro, Brazil.

BACKGROUND: Previous research suggests that unhealthy community food environments around schools contribute to unhealthy eating habits and negative health outcomes among the youth. However, little is known about how socioeconomic inequalities in those community food environments are associated with food deserts and food swamps across schools' neighborhoods. METHODS: An ecological study was carried out in all 3,159 public and private schools in Rio de Janeiro, Brazil. Three measures of socioeconomic inequality were evaluated: per capita income, segregation index and deprivation index. The community school food environment was analyzed by metrics of food swamps and food deserts. RESULTS: Food deserts and food swamps were simultaneously more prevalent in neighborhoods of the lowest income, high deprivation, and high segregation. Spatial socioeconomic disparities at the neighborhoods of schools were associated with food deserts and food swamps in Rio de Janeiro. CONCLUSIONS: Our results point to a spatial socioeconomic inequality of establishments that sell food around schools in a Brazilian metropolis, indicating that the areas of greatest deprivation of food services are also the areas with the worst socioeconomic characteristics.

Satisfaction with the Neighborhood of Israeli and Chilean Children and its Effects on their Subjective Well-being.

A study of subjective well-being in 4,942 children (49% girls) aged 10 and 12 living in Israel and Chile is presented. The association between perceptions of the neighborhood and subjective well-being (SWB) was analyzed based on a mediation model using satisfaction with the neighborhood as a mediating variable. The overall results showed high average SWB scores for both countries as well as high levels of satisfaction with the neighborhoods where they live. Differences between the countries were observed for the age groups. The SWB of Chilean children decreased with age, while a decrease was not detected for the Israeli children. The mediation model had excellent fit for the age groups and countries, and the satisfaction with the neighborhood variable presents a partial mediation effect between neighborhood variables and SWB. Satisfaction with the neighborhood displayed a greater effect on the SWB of the older children than the younger ones. Gender showed significant effects on SWB only in Chile. The results are discussed, analyzing the similarities and differences between both countries and providing new evidence for the study of SWB at the international level. Questions for a more specific analysis of SWB within each country are suggested.

The influence of neighborhood safety and built environment on childhood obesity: isolated and combined effect of contextual factors / A influência da segurança da vizinhança e do ambiente construído sobre a obesidade infantil: efeitos isolado e combinado de fatores contextuais / La influencia de la seguridad del vecindario y el ambiente construido sobre la obesidad infantil: efectos aislados y combinados de los factores contextuales

Abstract: This study aims to analyze the isolated and combined effect of objective measures concerning neighborhood safety, food, and physical activity environments on students' obesity. This is a cross-sectional study conducted with 9- and 10-year-old children enrolled in the municipal education network of a Brazilian metropolis. Environment objective measures comprised neighborhood unsafety (annual criminality and road traffic accident rates), availability of public parks and spaces for physical activity practicing, and index of establishments that predominantly sell ultra-processed food. Euclidean buffers of 1,000m around the children's house were used as eligible geographic units. This study adopted the Principal Component Analysis and Generalized Estimation Equation models. Stratified analyses were conducted based on neighborhood unsafety and on child's family income. In total, 717 students were assessed, 12.2% of them were children with obesity. The latent variable of the obesogenic environment (deduced by environment unsafety rates and the index of establishments that predominantly sell ultra-processed food) was a risk factor for obesity in children with lower socioeconomic levels (OR = 2.37; 95%CI: 1.06-5.19). Public parks and spaces for physical activity practicing were protective factors against childhood obesity only in locations recording the lowest environment unsafety rates (OR = 0.30; 95%CI: 0.09-0.94). Based on our findings, social conditions change the effect of the environment on childhood obesity, reinforcing the relevance of inter-sectoral policies and strategies against this condition.

Resumo: Este artigo busca analisar os efeitos isolado e combinado de medidas objetivas relativas à segurança da vizinhança, alimentação e ambientes de atividade física sobre a obesidade de crianças em idade escolar. Este estudo transversal foi realizado com crianças de 9 e 10 anos de idade que estavam matriculadas na rede municipal de ensino de uma metrópole brasileira. As medidas objetivas ambientais incluíram a insegurança nos bairros (índices anuais de criminalidade e acidentes de trânsito), disponibilidade de logradouros e espaços públicos para a prática de atividade física e o índice de estabelecimentos que comercializam majoritariamente alimentos ultraprocessados. Um buffer euclidiano de 1.000m em torno da casa das crianças foi tomado como unidade geográfica elegível. Nossa análise englobou os modelos de Análise de Componentes Principais e de Estimação de Equação Generalizada. Análises estratificadas foram realizadas com base na insegurança da vizinhança e na renda familiar da família da criança. Avaliamos 717 estudantes, 12,2% dos quais eram obesos. A variável latente ambiente obesogênico (deduzida das taxas de insegurança ambiental e do índice de estabelecimentos que comercializam majoritariamente alimentos ultraprocessados) constituiu o fator de risco para obesidade em crianças em famílias de baixa renda (OR = 2,37; IC95%: 1,06-5,19). Parques e espaços públicos para a prática de atividade física foram fatores de proteção contra a obesidade infantil apenas nos locais que registraram as menores taxas de insegurança ambiental (OR = 0,30; IC95%: 0,09-0,94). Com base em nossos achados, a condição social modifica o efeito do ambiente sobre a obesidade infantil e reforça a relevância de políticas e estratégias intersetoriais para prevenir a obesidade infantil.

Resumen: Este artículo busca analizar los efectos aislados y combinados de medidas objetivas relacionadas con la seguridad del vecindario, la alimentación y los ambientes de actividad física sobre la obesidad de los niños en edad escolar. Este estudio transversal fue realizado con niños de 9 y 10 años de edad que estaban matriculados en la red municipal de enseñanza de una metrópoli brasileña. Las medidas objetivas ambientales incluyeron la inseguridad en los barrios (índices anuales de criminalidad y accidentes de tránsito), disponibilidad de espacios públicos para la práctica de actividad física y el índice de establecimientos que comercializan mayoritariamente alimentos ultraprocesados. Se tomó como unidad geográfica elegible un buffer euclidiano de 1.000 metros en torno a la casa de los niños. Nuestro análisis abarcó los modelos de Análisis de Componentes Principales y Estimación de Ecuaciones Generalizadas. Se realizaron análisis estratificados basados en la inseguridad del vecindario y en los ingresos de la familia del niño. Evaluamos a 717 estudiantes, de los cuales el 12,2% eran obesos. La variable latente ambiente obesogénico (deducida de las tasas de inseguridad ambiental y del índice de establecimientos que comercializan mayoritariamente alimentos ultraprocesados) constituyó el factor de riesgo de obesidad en niños de familias con bajos ingresos (OR = 2,37; IC95%: 1,06-5,19). Los parques y espacios públicos para la práctica de actividad física fueron factores de protección contra la obesidad infantil solo en los lugares que registraron las menores tasas de inseguridad ambiental (OR = 0,30; IC95%: 0,09-0,94). Sobre la base de nuestros hallazgos, la condición social modifica el efecto del ambiente sobre la obesidad infantil y refuerza la relevancia de las políticas y estrategias intersectoriales para prevenir la obesidad infantil.

Effect of prevalence of alcohol consumption and tobacco use in Mexican municipalities on early childhood development / Efecto de la prevalencia del consumo de alcohol y tabaco en municipios mexicanos sobre el desarrollo durante la primera infancia / Efeito da prevalência do consumo de álcool e tabaco em municípios mexicanos sobre o desenvolvimento durante a primeira infância

Abstract: One of the most critical time periods in childhood is from birth to five years of age. Children exposed to alcohol and/or tobacco via family members and neighborhood are at risk for childhood developmental delays. This study evaluated the association of early childhood development with the prevalence of alcohol consumption and tobacco use in Mexican municipalities. This is a cross-sectional study. Early childhood development information from 2,345 children aged from 36 to 59 months was obtained from the 2015 Mexican National Survey of Boys, Girls, and Women (ENIM). Data on alcohol consumption and tobacco use come from the 2016 Mexican National Survey on Drugs, Alcohol, and Tobacco Consumption (ENCODAT). Multilevel logistic models were fitted to evaluate the association of the prevalence of alcohol consumption and tobacco use with the inadequacy of early childhood development. Children living in municipalities with high prevalence of alcohol consumption (OR = 13.410; 95%CI: 2.986; 60.240) and tobacco use (OR = 15.080; 95%CI: 2.040; 111.400) were less likely to be developmentally on track regarding early childhood development after adjustment for individual variables related to the child's development and other environmental variables at municipal level. Childhood exposure to alcohol and tobacco in the neighborhood may directly contribute to inadequate early childhood development. These findings suggest that there is an urgent need to develop effective interventions aimed at reducing alcohol consumption and tobacco use in municipalities to ensure adequate early childhood development.

Resumen: El grupo de edad que se extiende desde el nacimiento hasta los 5 años es uno de los periodos más críticos en la infancia. Niños expuestos al alcohol y/o al tabaco a través de la familia y vecinos corren el riesgo de sufrir un retraso en el desarrollo infantil. Este estudio evaluó la asociación del desarrollo durante la primera infancia con la prevalencia del consumo de alcohol y tabaco en municipios mexicanos. Se trata de un estudio transversal. Las informaciones sobre el desarrollo durante la primera infancia de 2.345 niños de 36 a 59 meses se obtuvieron a través de la Encuesta Nacional de los Niños, Niñas y Mujeres en México (ENIM) de 2015. Los datos sobre el consumo de alcohol y tabaco son de la Encuesta Nacional de Consumo de Drogas, Alcohol y Tabaco en México (ENCODAT) de 2016. Se ajustaron los modelos logísticos multiniveles para evaluar la asociación de la prevalencia de consumo de alcohol y tabaquismo con desarrollo durante la primera infancia inadecuado. Los niños que viven en municipios que tienen una alta prevalencia de consumo de alcohol (OR = 13,410; IC95%: 2,986; 60,240) y tabaquismo (OR = 15,080; IC95%: 2,040; 111,400) se asociaron con la probabilidad más alta de tener un desarrollo durante la primera infancia inadecuado tras el ajuste de las variables individuales relacionadas al desarrollo del niño y a otras variables ambientales en nivel municipal. La exposición infantil al alcohol y al tabaco en la vecindad puede contribuir directamente a un desarrollo durante la primera infancia inadecuado. Estos hallazgos indican una necesidad urgente de desarrollar intervenciones eficaces destinadas a reducir el consumo de alcohol y tabaquismo en los municipios para asegurar un desarrollo durante la primera infancia adecuado.

Resumo: A faixa etária que se estende do nascimento aos 5 anos de idade é um dos períodos mais críticos na infância. Crianças expostas ao álcool e/ou tabaco por meio de familiares e vizinhos estão em risco de atraso no desenvolvimento infantil. Este estudo avaliou a associação do desenvolvimento durante a primeira infância com a prevalência do consumo de álcool e tabaco em municípios mexicanos. Trata-se de um estudo transversal. As informações sobre o desenvolvimento durante a primeira infância de 2.345 crianças de 36 a 59 meses foram obtidas pela Pesquisa Nacional Sobre Crianças e Mulheres no México (ENIM) de 2015. Os dados sobre consumo de álcool e tabaco são da Pesquisa Nacional sobre Consumo de Drogas, Álcool e Tabaco no México (ENCODAT) de 2016. Modelos logísticos multiníveis foram ajustados para avaliar a associação da prevalência de consumo de álcool e tabagismo com desenvolvimento durante a primeira infância inadequado. Crianças que vivem em municípios com alta prevalência de consumo de álcool (OR = 13,410; IC95%: 2,986; 60,240) e tabagismo (OR = 15,080; IC95%: 2,040; 111,400) foram associadas à maior probabilidade de ter um desenvolvimento durante a primeira infância inadequado após ajuste às variáveis individuais relacionadas ao desenvolvimento da criança e a outras variáveis ambientais em nível municipal. A exposição infantil ao álcool e tabaco na vizinhança pode contribuir diretamente para o desenvolvimento durante a primeira infância inadequado. Estas descobertas demonstram uma necessidade urgente de desenvolver intervenções eficazes destinadas a reduzir o consumo de álcool e tabagismo nos municípios para garantir um desenvolvimento durante a primeira infância adequado.

Desordem física e social da vizinhança em cidades da América Latina: revisão de escopo / Desorden físico y social del vecindario en las ciudades de América Latina: revisión de alcance / Physical and social neighborhood disorder in Latin American cities: a scoping review

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.

Spatial clusters of diabetes: individual and neighborhood characteristics in the ELSA-Brasil cohort study / Aglomerados espaciais de diabetes: características individuais e de vizinhança no estudo longitudinal ELSA-Brasil / Grupos espaciales de diabetes: características individuales y vecinales en el estudio longitudinal ELSA-Brasil

This study identified spatial clusters of type 2 diabetes mellitus among participants of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) residing in two cities and verified individual and neighborhood socioeconomic environmental characteristics associated with the spatial clusters. A cross-sectional study was conducted with 4,335 participants. Type 2 diabetes mellitus was defined as fasting blood glucose ≥ 126mg/dL (7.0mmol/L), oral glucose tolerance test ≥ 200mg/dL (11.1mmol/L), or glycated hemoglobin ≥ 6.5% (48mmol/L); by antidiabetic drug use; or by the self-reported medical diagnosis of type 2 diabetes mellitus. Neighborhood socioeconomic characteristics were obtained from the 2011 Brazilian census. A spatial data analysis was conducted with the SaTScan method to detect spatial clusters. Logistic regression models were fitted to estimate the magnitude of associations. In total, 336 and 343 participants had type 2 diabetes mellitus in Belo Horizonte, Minas Gerais State (13.5%) and Salvador, Bahia State (18.5%), respectively. Two cluster areas showing a high chance of type 2 diabetes mellitus were identified in Belo Horizonte and Salvador. In both cities, participants living in the high type 2 diabetes mellitus cluster area were more likely to be mixed-race or black and have a low schooling level and manual work; these were also considered low-income areas. On the other hand, participants in the low type 2 diabetes mellitus cluster area of Salvador were less likely to be black and have low schooling level (university degree) and live in a low-income area. More vulnerable individual and neighborhood socioeconomic characteristics were associated with living in clusters of higher type 2 diabetes mellitus occurrence , whereas better contextual profiles were associated with clusters of lower prevalence.

Este estudo identificou aglomerados espaciais de diabetes mellitus tipo 2 entre participantes do Estudo Longitudinal de Saúde do Adulto no Brasil (ELSA-Brasil) em duas cidades e verificou características socioeconômicas ambientais individuais e de vizinhança associadas aos aglomerados espaciais. Se trata de um estudo transversal com 4.335 participantes. Diabetes mellitus tipo 2 foi definido com base em glicemia de jejum ≥ 126mg/dL (7,0mmol/L); teste oral de tolerância à glicose ≥ 200mg/dL (11,1mmol/L); hemoglobina glicada ≥ 6,5% (48mmol/L); uso de drogas antidiabéticas; ou pelo autodiagnóstico médico de diabetes mellitus tipo 2. As características socioeconômicas do bairro foram obtidas a partir do censo brasileiro de 2011. A análise dos dados espaciais foi realizada pelo método SaTScan para detectar os aglomerados espaciais. Os modelos de regressão logística foram ajustados para estimar a magnitude das associações. Um total de 336 e 343 participantes apresentaram diabetes mellitus tipo 2 em Belo Horizonte, Minas Gerais (13,5%) e Salvador, Bahia (18,5%), respectivamente. Foram identificadas duas áreas de aglomerados com alta probabilidade de diabetes mellitus tipo 2 em Belo Horizonte e Salvador. Em ambas as cidades, os participantes residentes nos aglomerados com alta taxa de diabetes mellitus tipo 2 tinham maior probabilidade de relatar cor de pele parda ou preta, baixa escolaridade e ocupação de trabalho manual; essas áreas também foram consideradas de baixa renda. Por outro lado, os participantes do aglomerado com baixa taxa de diabetes mellitus tipo 2 de Salvador tinham menor probabilidade de serem negros e maior probabilidade de terem diploma universitário, além de morarem em áreas de alta renda. Características socioeconômicas individuais e de vizinhança mais vulneráveis estavam associadas à residência em aglomerados de maior ocorrência de diabetes mellitus tipo 2, enquanto o oposto foi observado para perfis contextuais melhores.

Este estudio identificó grupos espaciales de diabetes mellitus tipo 2 entre los participantes del Estudio Longitudinal de Salud del Adulto en Brasil (ELSA-Brasil) en dos ciudades y verificó las características socioeconómicas ambientales individuales y de vecindario asociadas con los grupos espaciales. Se trata de un estudio transversal con 4.335 participantes. La diabetes mellitus tipo 2 se definió en base a glucosa en ayunas ≥ 126mg/dL (7,0mmol/L); prueba de tolerancia oral a la glucosa ≥ 200mg/dL (11,1mmol/L); hemoglobina glicosilada ≥ 6,5% (48mmol/L); uso de medicamentos antidiabéticos; o por autodiagnóstico médico de diabetes mellitus tipo 2. Las características socioeconómicas del barrio se obtuvieron a partir del censo brasileño de 2011. El análisis de datos espaciales se realizó utilizando el método SaTScan para detectar grupos espaciales. Los modelos de regresión logística se ajustaron para estimar la magnitud de las asociaciones. Un total de 336 y 343 participantes presentaron diabetes mellitus tipo 2 en Belo Horizonte, Minas Gerais (13,5%) y Salvador, Bahia (18,5%), respectivamente. Se identificaron dos áreas de grupos con alta probabilidad de diabetes mellitus tipo 2 en Belo Horizonte y Salvador. En ambas ciudades, los participantes que residían en las áreas del grupo con una alta tasa de diabetes mellitus tipo 2 tenían más probabilidades de informar el color de piel pardo o negro, la baja educación y la ocupación del trabajo manual; estas áreas también se consideraron de bajos ingresos. Por el contrario, los participantes en el área del grupo con baja tasa de diabetes mellitus tipo 2 de Salvador tenían menos probabilidades de ser negros y más probabilidades de tener un título universitario, además de vivir en áreas de altos ingresos. Las características socioeconómicas individuales y de vecindario más vulnerables se asociaron con la residencia en grupos de mayor incidencia de diabetes mellitus tipo 2, mientras que se observó lo contrario para mejores perfiles contextuales.
