Pessoas idosas que moram sozinhas: análise de demanda para os serviços sociais e saúde / Older adults living alone: demand analysis for social and health services / Personas ancianas que viven solas: análisis de la demanda de servicios sociales y de salud

Objetivo: Analisar as condições sociais, demográficas, econômicas, de vida e saúde, de apoio social e cuidado de pessoas idosas que moram sozinhas. Método: Estudo transversal com abordagem quantitativa por meio de uma entrevista com questionário semiestruturado com idosos. Utilizou-se uma análise univariada a partir do teste qui-quadrado, de análise de correspondência múltipla e de cluster pelo procedimento não hierárquico. Resultados: Foram encontrados quatro principais agrupamentos de pessoas idosas que moram só, sendo eles: o primeiro, dos mais longevos com comorbidades respiratórias e que precisam de ajuda regularmente; o segundo, de idosos sem apoio a que recorrer; o terceiro, composto por homens com mais apoio; e o quarto, de mulheres mais independentes de apoio e cuidado. Conclusão: Esse diagnóstico da situação de pessoas idosas que vivem sozinhas evidencia um impacto direto e indireto nos serviços sociais e de saúde, subsidiando reformulações e implantações de políticas públicas de apoio e cuidado

Objective: To analyze the social, demographic, economic, living, and health conditions, social support, and care of older adults who live alone. Method: Cross-sectional study with a quantitative approach using a semi-structured questionnaire interview with older adults. A univariate analysis was carried out with the chi-square test, multiple correspondence analysis and cluster analysis with a non-hierarchical procedure. Results: There was statistical significance among the variables sex (p=0.013), marital status (p<0.001), financial head of the household (p<0.001), contribution to family support (p=0.038), indebtedness (p=0.034), kidney disease (p=0.009), and all the social support and care variables (p≤0.05). Four groups were found in which longest-lived adults have comorbidities (pulmonary and respiratory disease) and need help regularly, older adults have no support, men have more support, and women are more independent of support and care. Conclusion: This diagnosis of the situation of older adults living alone supports the implementation of public support and care policies

City features related to obesity in preschool children: a cross-sectional analysis of 159 cities in six Latin American countries.

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.

Patients from distressed communities are more likely to be symptomatic at endovascular aneurysm repair and have an increased risk of being lost to long-term follow-up.

BACKGROUND: Endovascular aortic aneurysm repair (EVAR) has become the preferred modality to repair abdominal aortic aneurysms (AAAs). However, the effect of the distressed communities index (DCI) on the outcomes of EVAR is still unknown. In the present study, we investigated the effect of DCI on the postoperative outcomes after EVAR. METHODS: The Society for Vascular Surgery Vascular Quality Initiative database was used for the present study. Patients who had undergone EVAR from 2003 to 2021 were selected for analysis. The study cohort was divided into two groups according to their DCI score. Patients with DCI scores ranging from 61 to 100 were assigned to group I (DCI >60), and those with DCI scores ranging from 0 to 60 were assigned to group II (DCI ≤60). The primary outcomes included the 30-day and 1-year mortality and major adverse cardiovascular events at 30 days. Regression analyses were performed to study the postoperative outcomes. P values ≤ .05 were deemed statistically significant for all analyses in the present study. RESULTS: A total of 60,972 patients (19.5% female; 80.5% male) had undergone EVAR from 2003 to 2021. Of these patients, 18,549 were in group I (30.4%) and 42,423 in group II (69.6%). The mean age of the study cohort was 73 ± 8.9 years. Group I tended to be younger (mean age, 72.6 vs 73.7 years), underweight (3.5% vs 2.5%), and African American (10.8% vs 3.5%) and were more likely to have Medicaid insurance (3.6% vs 1.9%; P < .05 for all). Group I had had more smokers (87.3% vs 85.3%), a higher rate of comorbidities, including hypertension (84.5% vs 82.9%), diabetes (21.7% vs 19.7%), coronary artery disease (30.3% vs 28.6%), chronic obstructive pulmonary disease (36.9% vs 31.8%), and moderate to severe congestive heart failure (2.6% vs 2%; P < .05 for all). The group I patients were more likely to undergo EVAR for symptomatic AAAs (11.1% vs 7.9%; P < .001; adjusted odds ratio [aOR], 1.25; 95% confidence interval [CI], 1.15-1.37; P < .001) with a higher risk of mortality at 30 days (aOR, 3.98; 95% CI, 2.23-5.44; P < .001) and 1 year (aOR, 1.74; 95% CI, 1.43-2.13; P < .001). A higher risk of being lost to follow-up (28.9% vs 26.3%; P < .001) was also observed in group I. CONCLUSIONS: Patients from distressed communities who require EVAR tended to have multiple comorbidities. These patients were also more likely to be treated for symptomatic AAAs, with a higher risk of mortality. An increased incidence of lost to long-term follow-up was also observed for this population. Surgeons and healthcare systems should consider these outcomes and institute patient-centered approaches to ensure equitable healthcare.

Modelagem GAMLSS espaçotemporal da incidência de esquistossomose na região central do Estado de Minas Gerais, Brasil / Modelado espaciotemporal GAMLSS para la incidencia de esquistosomiasis en la región central del estado de Minas Gerais, Brasil / Spatio-temporal GAMLSS modeling of the incidence of schistosomiasis in the central region of the State of Minas Gerais, Brazil

Resumo: No Brasil, milhões de pessoas vivem em áreas de risco para a esquistossomose, uma doença negligenciada, de caráter crônico e com elevada morbidade. O helminto Schistosoma mansoni está presente em todas as macrorregiões, incluindo o Estado de Minas Gerais, um dos mais endêmicos. Por essa razão, a identificação de potenciais focos é fundamental para subsidiar políticas públicas de cunho educativo e profilático no controle desse desfecho. Nesse contexto, o objetivo do trabalho consiste em modelar dados de esquistossomose em relação aos aspectos espaciais e temporais, além de avaliar a importância de algumas variáveis exógenas socioeconômicas e a presença das principais espécies de Biomphalaria. Como trabalhar com casos incidentes, uma variável discreta de contagem, exige uma modelagem apropriada, foi escolhida a modelagem GAMLSS por considerar conjuntamente uma distribuição mais adequada à variável resposta devido à inflação de zeros e à heterocedasticidade espacial. Verificaram-se valores elevados de incidência em diversos municípios de 2010 a 2012 e uma tendência de queda até 2020. Também foi identificado que a distribuição da incidência se comporta de maneira diferente no espaço e no tempo. Municípios com barragem apresentaram risco 2,25 vezes maior do que os que não a continham. A presença de B. glabrata foi relacionada ao risco de ocorrência da doença. Por outro lado, a presença de B. straminea refletiu em menor risco de ocorrência da esquistossomose. Conclui-se que o controle e o acompanhamento dos caramujos da B. glabrata podem ser fundamentais para a contenção e a eliminação da esquistossomose e o modelo GAMLSS foi eficaz para tratamento e modelagem de dados espaçotemporais.

Resumen: En Brasil, millones de personas viven en áreas de riesgo de esquistosomiasis, una enfermedad crónica desatendida y con alta morbilidad. El helminto Schistosoma mansoni está presente en todas las macrorregiones, incluido el Estado de Minas Gerais, uno de los más endémicos del país. Por ello, la identificación de potenciales brotes es fundamental para promover políticas públicas de carácter educativo y profiláctico en el control de este desenlace. En este contexto, el objetivo de este trabajo es modelar datos sobre esquistosomiasis con respecto a aspectos espaciotemporales, además de evaluar la importancia de algunas variables socioeconómicas exógenas y la presencia de las principales especies de Biomphalaria. Dado que en el trabajo con casos incidentes una variable de conteo discreta requiere un adecuado modelado, se eligió el modelo GAMLSS, ya que en conjunto considera una distribución más adecuada para la variable de respuesta debido a la inflación de ceros y la heterocedasticidad espacial. Se encontraron valores de alta incidencia en varios municipios en el periodo evaluado de 2010 a 2012 y una tendencia a descenso hasta 2020. También se verificó que existe una distribución de incidencia de manera diferente en el espacio y el tiempo. Los municipios con represas presentaban 2,25 veces más riesgo que los que no las tenían. La presencia de B. glabrata estuvo relacionada con el riesgo de la enfermedad. Por otro lado, la presencia de B. straminea ocasionaba un menor riesgo de padecer la enfermedad. Se concluye que el control y seguimiento de caracoles B. glabrata puede ser fundamental para el control y eliminación de la esquistosomiasis y que el modelo GAMLSS resultó ser efectivo para el tratamiento y modelado de datos espaciotemporales.

Abstract: In Brazil, millions of people live in areas with risk of schistosomiasis, a neglected chronic disease with high morbidity. The Schistosoma mansoni helminth is present in all macroregions of Brazil, including the State of Minas Gerais, one of the most endemic states. For this reason, the identification of potential foci is essential to support educational and prophylactic public policies to control this disease. This study aims to model schistosomiasis data based on spatial and temporal aspects and assess the importance of some exogenous socioeconomic variables and the presence of the main Biomphalaria species. Considering that, when working with incident cases, a discrete count variable requires an appropriate modeling, the GAMLSS modeling was chosen since it jointly considers a more appropriate distribution for the response variable due to zero inflation and spatial heteroscedasticity. Several municipalities presented high incidence values from 2010 to 2012, and a downward trend was observed until 2020. We also noticed that the distribution of incidence behaves differently in space and time. Municipalities with dams presented risk 2.25 times higher than municipalities without dams. The presence of B. glabrata was associated with the risk of schistosomiasis. On the other hand, the presence of B. straminea represented a lower risk of the disease. Thus, the control and monitoring of B. glabrata snails is essential to control and eliminate schistosomiasis; and the GAMLSS model was effective in the treatment and modeling of spatio-temporal data.

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.

Is neighborhood income associated with untreated dental caries irrespective of family income?

OBJECTIVE: To assess the status of untreated dental caries in adolescents exposed to different conditions of family and neighborhood income. MATERIALS AND METHODS: This cross-sectional study included a representative sample of 1197 15-19-year-old adolescents attending high schools from Santa Maria, southern Brazil. Data collection included a questionnaire and clinical examination (DMFT index). Neighborhood mean income was collected from official sources. The main predictor variable was a combination of household income and neighborhood mean income resulting in four categories: low household income/low neighborhood income, low household income/high neighborhood income, high household income/low neighborhood income, or high household income/high neighborhood income. The outcome was untreated caries (number of teeth with dentin cavities or residual roots). Multilevel Poisson regression analysis was used to assess the association between predictors and untreated caries. Rate ratio (RR) and 95% confidence intervals (CI) were estimated. RESULTS: The prevalence of untreated dental caries was 26% (n = 312), with a mean (± standard deviation) of 0.47 (± 1.05) teeth. Adolescents with low household income living in areas with low neighborhood income had the worse caries scenario. Compared with them, those classified as low-income households residing in high-income neighborhoods had 37% lower rate of untreated dental caries (adjusted RR = 0.63; 95%CI = 0.44-0.89). No neighborhood effect was detected among adolescents of more affluent families. CONCLUSIONS: Neighborhood income contributed to the rate of untreated dental caries over and above household income among adolescents with low household income only. CLINICAL RELEVANCE: Improving living conditions in disadvantaged neighborhoods may positively impact the oral health of residents, thus reducing oral health inequalities.

Distribuição e dependência espacial da mortalidade por tuberculose em um município da região amazônica / Spatial distribution and dependence of mortality due to tuberculosis in a city in the Amazon region

Resumo Introdução A mortalidade por tuberculose é um indicador sensível às desigualdades em saúde, considerando-se que o risco para sua ocorrência está relacionado à vulnerabilidade dos territórios. Objetivo Investigar se as variações espaciais dos determinantes sociais afetam as mortes por tuberculose em um município da região amazônica. Método Estudo ecológico com medidas múltiplas de análise, composto por óbitos por tuberculose como causa básica em Manaus, Amazonas, Brasil, notificados no Sistema de Informação sobre Mortalidade (2006-2015). Nas análises, foram calculadas as taxas bruta e padronizada, e usado o Índice de Moran para verificar a autocorrelação espacial da mortalidade e, posteriormente, foi aplicada a regressão geograficamente ponderada para aferir a relação da desigualdade com as mortes por tuberculose. Resultados Foram identificados 731 óbitos pela doença. A distribuição da mortalidade ocorreu de forma heterogênea, sendo que as altas taxas de óbito por tuberculose estavam em áreas mais socialmente vulneráveis. Foram confirmadas a autocorrelação e a dependência espacial. O modelo final apresentou as variáveis indicadoras de iniquidades (baixa renda, pobreza e escolaridade), mostrando relação destas com a mortalidade. Conclusão Ficou evidente que os determinantes sociais no espaço urbano influenciam a mortalidade por tuberculose na região. Portanto, avançar em políticas públicas para corrigir as iniquidades em saúde pode influenciar positivamente esse cenário.

Abstract Background Mortality from tuberculosis is a sensitive indicator of health inequalities, given that the risk for its occurrence is related to the vulnerability of the territories. Objective To investigate whether the spatial variations of social determinants affect deaths from tuberculosis in a municipality in the Amazon region. Method Ecological study with multiple measures of analysis. The study was composed of deaths from tuberculosis as a basic cause in Manaus, Amazonas, Brazil, reported in the Brazilian Mortality Information System (2006-2015). In the analyzes, the crude and standardized rate was calculated, Moran Index was used to verify the spatial autocorrelation of mortality, and subsequently, the geographically weighted regression was applied to assess the inequality relationship of deaths from tuberculosis. Results 731 deaths from the disease were identified. The distribution of mortality was heterogeneous, with high rates of death from tuberculosis in more socially vulnerable areas. The autocorrelation and spatial dependence was confirmed. The final model presented variables that indicate inequities: low income, poverty and education, showing their relationship with mortality. Conclusion It was evident that social determinants in the urban space influence mortality from tuberculosis in the region. Therefore, advancing public policies to correct health inequities can positively impact this scenario.

Dynamic geographical accessibility assessments to improve health equity: protocol for a test case in Cali, Colombia.

This protocol proposes an approach to assessing the place of residence as a spatial determinant of health in cities where traffic congestion might impact health services accessibility. The study provides dynamic travel times presenting data in ways that help shape decisions and spur action by diverse stakeholders and sectors.  Equity assessments in geographical accessibility to health services typically rely on static metrics, such as distance or average travel times. This new approach uses dynamic spatial accessibility measures providing travel times from the place of residence to the health service with the shortest journey time. It will show the interplay between traffic congestion, accessibility, and health equity and should be used to inform urban and health services monitoring and planning. Available digitised data enable efficient and accurate accessibility measurements for urban areas using publicly available sources and provide disaggregated sociodemographic information and an equity perspective. Test cases are done for urgent and frequent care (i.e., repeated ambulatory care). Situational analyses will be done with cross-sectional urban assessments; estimated potential improvements will be made for one or two new services, and findings will inform recommendations and future studies. This study will use visualisations and descriptive statistics to allow non-specialized stakeholders to understand the effects of accessibility on populations and health equity. This includes "time-to-destination" metrics or the proportion of the people that can reach a service by car within a given travel time threshold from the place of residence. The study is part of the AMORE Collaborative Project, in which a diverse group of stakeholders seeks to address equity for accessibility to essential health services, including health service users and providers, authorities, and community members, including academia.

Influence of Women´s Residence Region on Assisted Reproduction Treatments - Experience of a Tertiary Center in Northern Portugal.

OBJECTIVE: Data on the possible influence of women´s region of residence, within the same country, on the outcomes of medically assisted reproduction cycles are scarce. This study aims to assess the impact of the women's region of residence on the results of in-vitro fertilization cycles. METHODS: We evaluated in-vitro fertilization cycles between 2010 and 2017, performed in a northern Portugal assisted reproduction center. We defined two groups: Douro Litoral (group 1; n=783), and Trás-os-Montes and Alto Douro (group 2; n=178). We analyzed demographics and cycle-related variables, and we calculated the rates for embryo transfer cycles. We used the Mann-Whitney and Chi-square tests and p<0.05 was considered statistically significant. RESULTS: We included 961 cycles. The region of residence had no effect on the following variables: women´s age; body mass index; or duration of infertility (p>0.05). Group 2 had a statistical significant lower number of previous cycles than group 1 (1.3±0.5 and 1.5±0.7; p=0.005). In the sub-analysis of cycles with embryo transfer (n=781), group 1 obtained had rates of normal fertilization (62.5% vs. 57.5%; p=0.04), miscarriage rate (30.0 vs. 10.9%; p=0.007), and lower implantation rates compared to group 2 (33.3% vs. 50.0%; p<0.001). CONCLUSIONS: Women from the region of Trás-os-Montes e Alto Douro had a lower number of previous cycles, compared to those from the Douro Litoral, despite the absence of statistical significant differences in terms of age or infertility duration. These findings reinforce the need to contemplate the sociodemographic and socioeconomic variables in this context.

Association between the city region and traumatic dental injuries among adolescents from Santa Maria, South Brazil

Abstract This study investigated the association between the city region and traumatic dental injury (TDI) among adolescents from Santa Maria, Rio Grande do Sul, Brazil. A population-based cross-sectional survey was conducted from March to November 2018, which included a representative sample of adolescents (15-19-year-old) attending public and private high schools. A questionnaire on sociodemographic information was sent to the parents/legal guardians of the selected adolescents. TDI in the upper and lower permanent incisors and canines was recorded based on the O'Brien classification. Environmental variables (sociodemographic and structural characteristics of the neighborhoods) were obtained from official publications. Multilevel Poisson regression models were used, and prevalence ratios (PR) and 95% confidence intervals (CI) were calculated. A total of 1,146 adolescents participated in this study. The overall prevalence of TDI was 17.3%, mild trauma was 12.7%, and severe trauma was 5.8%. Adolescents living in the southern region had a prevalence of TDI of 25.3%, compared with 13.6% in the northern region. After adjusting for important cofactors, adolescents living in the southern region were more likely to have TDI than their counterparts in the northern region (PR, 1.91; 95%CI: 1.18-3.11; p = 0.009). Analyzing the number of environmental risk indicators in different regions, the southern region presented a higher mean and median than all other regions. In conclusion, living in the southern region was associated with a higher prevalence and severity of TDI among adolescents from Santa Maria, southern Brazil. Our findings suggest the role of the environment in the epidemiology of TDI.

Conclusão: Hubo una tasa estable de mujeres embarazadas infectadas por el VIH, mientras que el número de niños infectados por el VIH disminuyó.

Objective: To analyze the temporal trend and spatial distribution of mother-to-child HIV transmission in Santa Catarina between 2007 and 2017. Methods: This was a mixed ecological study with data from the Notifiable Health Conditions Information System. Linear regression was performed for time series analysis and the mean rates in the period and mean annual percentage changes in the rates of HIV-infected pregnant women were calculated, children exposed to HIV during pregnancy, and seroconversion of children exposed to HIV/AIDS during pregnancy, in addition to data geoprocessing. Results: There were 5,554 records of HIV-infected pregnant women, with a rate of 5.6 pregnant women per 1,000 live births. The mean seroconversion rate was 13.5/100,000 live births (95%CI 6.8;20.1) and it showed a falling trend (APC = -99.4%; 95%CI -99.9;-93.1). The seroconversion rate was more expressive in small towns. Conclusion: The rate of HIV-infected pregnant women was stable in the period, whereas the number of children infected with HIV through mother-to-child transmission decreased.

Self-perceived neighborhood factors and OHRQoL among adolescents: a population-based study in southern Brazil

Abstract This study aimed to assess the relationship between self-perceived neighborhood factors and oral health-related quality of life (OHRQoL) among adolescents from southern Brazil. A representative sample of 15-19-year-old students from Santa Maria, Brazil, was included. The Oral Health Impact Profile (OHIP-14) was used to assess the OHRQoL. Self-perceived neighborhood factors were assessed through a structured questionnaire and included characteristics of the neighborhood where the adolescents lived, such as the presence of paved streets, tap water, community social networks, and availability of dental services and the Family Health Strategy (FHS). In addition, socioeconomic, behavioral, and clinical variables (dental caries and malocclusion) were also evaluated. Multilevel Poisson regression analysis with a hierarchical approach was used to assess the association between predictors and OHIP-14. The rate ratio (RR) and 95% confidence intervals (CIs) were estimated. A total of 1,197 adolescents were included in this study (participation rate: 72.3%). The mean OHIP-14 score was 8.4 (standard error = 0.2), ranging from 0 to 49. Living in residences with unpaved streets (RR = 1.11, 95%CI:1.06−1.17), no tap water (RR = 1.11, 95%CI: 1.02−1.20), absence of the FHS services (RR = 1.15, 95%CI: 1.09−1.20), and the availability of dental services (RR = 1.08, 95%CI: 1.03−1.14) were associated with higher OHIP-14 scores, indicating a poorer OHRQoL. In addition, lower socioeconomic status, visiting the dentist for curative reasons, lower frequency of brushing teeth, and higher sugar consumption were also associated with higher OHIP-14 scores. In conclusion, self-perceived neighborhood characteristics were associated with OHRQoL in adolescents. Adolescents who perceived their neighborhood as deprived had poorer OHRQoL.

Quality of automatic geocoding tools: a study using addresses from hospital record files in Temuco, Chile / Calidad de las herramientas automáticas de geocodificación: un estudio usando direcciones de fichas de registro hospitalario en Temuco, Chile / A qualidade das ferramentas de geocodificação automática: um estudo utilizando endereços de prontuários hospitalares em Temuco, Chile

Abstract: Automatic geocoding methods have become popular in recent years, facilitating the study of the association between health outcomes and the place of living. However, rather few studies have evaluated geocoding quality, with most of them being performed in the US and Europe. This article aims to compare the quality of three automatic online geocoding tools against a reference method. A subsample of 300 handwritten addresses from hospital records was geocoded using Bing, Google Earth, and Google Maps. Match rates were higher (> 80%) for Google Maps and Google Earth compared with Bing. However, the accuracy of the addresses was better for Bing with a larger proportion (> 70%) of addresses with positional errors below 20m. Generally, performance did not vary for each method for different socioeconomic status. Overall, the methods showed an acceptable, but heterogeneous performance, which may be a warning against the use of automatic methods without assessing quality in other municipalities, particularly in Chile and Latin America.

Resumen: Los métodos automáticos de geocodificación se han convertido en algo popular durante los últimos años para facilitar el estudio de la asociación entre resultados de salud y lugar para vivir. No obstante, más bien pocos estudios han evaluado la calidad de la geocodificación, siendo realizados la mayoría de ellos en EE.UU. y Europa. El objetivo de este artículo es comparar la calidad de tres herramientas automáticas de geocodificación en línea frente a un método de referencia. La submuestra de 300 direcciones escritas a mano, procedentes del registro hospitalario, se geocodificaron usando Bing, Google Earth y Google Maps. Los porcentajes de coincidencia fueron mayores (> 80%) en el caso de Google Maps y Google Earth comparados con Bing. Sin embargo, la precisión de las direcciones fue mejor con Bing, en una proporción más grande (> 70%) de direcciones que tenían errores de posición por debajo de 20m. En general, el rendimiento no varió en cada método para diferentes niveles estatus socioeconómico. En general, los métodos mostraron un rendimiento aceptable, pero heterogéneo. Esto previene contra el uso de métodos automáticos sin evaluar la calidad en otras ciudades, particularmente en Chile y Latinoamérica.

Resumo: Os métodos de geocodificação automática se tornaram populares nos últimos anos para facilitar o estudo da associação entre desfechos de saúde e lugar de residência. Entretanto, poucos estudos avaliaram a qualidade da geocodificação, e a maioria dos estudos existentes foi realizada nos Estados Unidos e Europa. O estudo teve como objetivo comparar a qualidade de três ferramentas de geocodificação eletrônica automática em relação a um método de referência. Foi geocodificada uma subamostra de 300 endereços anotados à mão em prontuários hospitalares, usando Bing, Google Earth e Google Maps. As taxas de correspondência dos registros foram mais altas (> 80%) com Google Maps e Google Earth, comparado com Bing. Entretanto, a acurácia dos endereços foi melhor com Bing, com uma proporção maior (> 70%) de endereços com erros de localização menores que 20 metros. Em geral, o desempeno não variou para cada método de acordo com condição socioeconômica. Os métodos apresentaram desempenho geral aceitável, porém heterogêneo. Os resultados servem de alerta contra o uso de métodos automáticos sem avaliar a qualidade em outras cidades, particularmente no Chile e no resto da América Latina.

Incidence of hemoglobinopathies and spatialization of newborns with sickle cell trait in Mato Grosso do Sul, Brazil

ABSTRACT Objective To evaluate the incidence of variant hemoglobins of newborn samples from the Neonatal Screening Center in the state of Mato Grosso do Sul, Brazil, and to analyze the distribution and spatial autocorrelation of newborns with sickle cell trait. Methods Samples from 35,858 newborns screened by the Neonatal Screening Center. The samples with inconclusive diagnosis were submitted to electrophoretic, chromatographic, cytological and molecular analyses. The spatial distribution analysis of newborns with sickle cell trait was performed by spatial autocorrelation. Results A total of 919 newborns showed an abnormal hemoglobin profile; in that, ten genotypes had significant clinical impacts identified. Among the asymptomatic newborns, the sickle cell trait was the most frequent (incidence of 1.885 cases/100 newborns). The highest incidence rates were registered in the municipalities of Terenos, Figueirão, Corguinho and Selvíria. There was positive spatial autocorrelation between the proportion of declared individuals of black race/color and the incidence of newborns with sickle cell trait. Conclusion The early diagnosis by neonatal screening and laboratory tests was very important to identify abnormal hemoglobin profiles and guide the spatial autocorrelation analysis of sickle cell trait newborns in Mato Grosso do Sul, serving as a support to anticipate health measures aimed to discuss efficient therapeutic behaviors and effective planning of municipalities with the greatest need for care, monitoring and orientations for affected families.

Assessment of the contextual effects on the prevalence of periodontitis: a systematic review

Abstract This study reviews the influence of contextual factors on periodontitis based on a systematic search of studies recorded in the PubMed, Scopus, Web of Science, and EMBASE databases. Periodontitis was assessed by clinical attachment loss and probing depth for studies with data on the socioeconomic status (SES) of a specific area (area-level SES) or dental care service (service-level) in a catchment area among individuals aged 18 and over. Two independent reviewers performed study selection, data extraction, and assessment of methodological quality. Of the 646 articles identified, 13 were included in the systematic review, representing 101,362 individuals from five countries (USA, UK, Brazil, China, and Uruguay). A higher prevalence of periodontitis was described in lower SES neighborhoods, more deprived postcodes, and poorer provinces. Gini Index results were mixed and inconclusive. Three studies showed that higher coverage of primary dental care at the municipal level was associated with a lower prevalence of periodontitis. Contextual factors at the area-level SES and dental care service might influence periodontitis, but the existing evidence is unclear. The contextual effect is important for periodontal health and may contribute to the prevalence of periodontitis, independent of well-known risk factors and individual levels.

Cardiovascular Risk Factors and Social Development Index.

Cardiovascular diseases (CVD) are the leading causes of morbidity and mortality worldwide. The complex etiology of CVD is known to be significantly affected by environmental and social factors. There is, however, a lag in our understanding of how population level components may be related to the onset and severity of CVD, and how some indicators of unsatisfied basic needs might be related to known risk factors. Here, we present a cross-sectional study aimed to analyze the association between cardiovascular risk factors (CVRF) and Social Development Index (SDI) in adult individuals within a metropolitan urban environment. The six components of SDI as well as socioeconomic, anthropometric, clinical, biochemical, and risk behavior parameters were explored within the study population. As a result, several CVRF (waist circumference, waist-to-height ratio, body mass index, systolic blood pressure, glucose, lower high-density lipoprotein cholesterol, triglycerides, and sodium) were found in a higher proportion in the low or very low levels of the SDI, and this pattern occurs more in women than in men. Canonical analysis indicates a correlation between other socioeconomic features and anthropometric, clinical, and biochemical factors (canonical coefficient = 0.8030). Further studies along these lines are needed to fully establish how to insert such associations into the design of health policy and interventions with a view to lessen the burden of cardiovascular diseases, particularly in metropolitan urban environments.

Spatial density of adolescents aged 14 years old, victims of dental: A longitudinal study.

BACKGROUND/AIM: Knowledge about the spatial density of the domiciles of dental trauma victims can assist in the identification of the most vulnerable areas and contribute to the planning of prevention, promotion, control, and treatment actions, focusing on the most affected areas. The aim of this study was to analyze the spatial density of domiciles of 14-year-old adolescent victims of dental trauma, in the city of Diamantina, Brazil, after a two-year follow-up period. MATERIAL AND METHODS: This longitudinal study was carried out with 584 adolescents between 2013 and 2015. Dental trauma, overjet, and lip protection were assessed by two trained and calibrated examiners (K > 0.70). Information about binge drinking was collected among the adolescents through the Alcohol Use Disorders Identification Test and sociodemographic indicators were obtained through a questionnaire answered by the caregivers of the adolescents. Spatial analyses were performed to evaluate the spatial density of adolescents with dental trauma and the independent variables of interest according to the domicile using Ripley's K function and the Kernel Map. RESULTS: Ripley's K function revealed spatial aggregation of the domiciles of adolescent victims of dental trauma in relation to males, binge drinking and overjet, with a confidence interval of 95%. The higher density of domiciles with adolescents with two or more traumatized teeth was found in the north-east region of the city. Boys were the most affected, their homes were located in the north, north-west, and south-east regions at baseline and follow-up. The largest density of domiciles of adolescents with overjet greater than 5 mm and inadequate lip protection was in the north-east region. Similar spatial distribution was identified for binge drinking for both years. CONCLUSION: The majority of adolescents with dental trauma lived in the north-east and south-east regions, characterized by high population density and greater social vulnerability.

Home environment opportunities and motor development of infants in the first year / Oportunidades do ambiente domiciliar e desenvolvimento motor de lactentes no primeiro ano

Abstract Introduction: The home environment is a fundamental agent for infant development in the first year of life. Objective: To evaluate the opportunities for environmental stimulation and the motor development of infants at 3, 6, 9, and 12 months of age and determine the association between these opportunities and the parents' schooling and economic levels, at each age studied. Methods: This is a longitudinal study using the Alberta Infant Motor Scale (AIMS) to assess motor development, the Affordances in the Home Environment for Motor Development - Infant Scale (AHEMD-IS) questionnaire to assess the stimulation opportunities at home, and the Brazilian Association of Research Companies (ABEP) questionnaire to classify the economic level of the families. The association between opportunities for environmental stimulation and schooling and economic levels was determined by the chi-squared test. Results: Thirty-seven infants participated, 54.1% of whom were boys. At 3 months of age, the opportunities for environmental stimulation were unsatisfactory, while at 6, 9, and 12 months satisfactory opportunities predominated. Three infants scored below 10% on the AIMS at 3 months of age, indicating delayed motor development. There was a significant association between economic level and total AHEMD-IS score (p = 0.031), and the toy dimension for gross (p = 0.016) and fine (p = 0.043) motor skills. Conclusion: The infants' home environment did not provide sufficient opportunities for stimulation in the first months, but improved during the first year. Motor development was considered delayed for three infants, but was suitable in subsequent evaluations.

Resumo Introdução: O ambiente domiciliar é um agente fundamental para o desenvolvimento do lactente no primeiro ano de vida. Objetivo: Avaliar as oportunidades do ambiente domiciliar e o desenvolvimento motor de lactentes aos 3, 6, 9 e 12 meses de idade e verificar se há associação entre as oportunidades de estimulação e a escolaridade e nível econômico dos pais, em cada faixa etária estudada. Métodos: Estudo longitudinal, que utilizou o instrumento Alberta Infant Motor Scale para avaliar o desenvolvimento motor, o questionário Affordances in the Home Environment for Motor Development - Infant Scale (AHEMD-IS) para avaliar as oportunidades de estimulação oferecidas no domicílio e o questionário da Associação Brasileira de Empresas de Pesquisa para classificar o nível econômico das famílias. A associação entre as oportunidades de estimulação do ambiente e a escolaridade e nível econômico foi verifi-cada pelo teste qui-quadrado. Resultados: Participaram da pesquisa 37 lactentes, sendo 54,1% do sexo masculino. Aos 3 meses de idade, as oportunidades de estimulação do ambiente foram insatisfatórias. Aos 6, 9 e 12 meses, houve predomínio de oportunidades satisfatórias. Três lactentes apresentaram percentil inferior a 10% aos 3 meses de idade, indicando atraso do desenvolvimento motor. Houve associação significativa entre o nível econômico e a pontuação total do AHEMD-IS (p = 0,031), a dimensão brinquedos de motricidade grossa (p = 0,016) e fina (p = 0,043). Conclusão: O ambiente domiciliar dos lactentes estudados apresentou oportunidades insuficientes para estimulação nos primeiros meses, melhorando ao longo do primeiro ano. O desenvolvimento motor foi considerado atrasado para três lactentes, tornando-se adequado nas avaliações subsequentes.

Noise annoyance, sociodemographic and health patterns, and neighborhood perceptions in a Brazilian metropolis: BH Health Study / Percepção do ruído como incômodo, características sociodemográficas, de saúde e percepção da vizinhança em uma metrópole brasileira: Estudo Saúde em Beagá

ABSTRACT Objective: The present study aims to analyze the association of noise annoyance with individual and sociodemographic factors and self-perception of the neighborhood in an urban center. Methods: Data were collected through a population-based cross-sectional study held in two of the nine health districts in the city of Belo Horizonte, Minas Gerais, Brazil, from 2008 to 2009. The study included 3,934 individuals of both genders, aged 18 years and older. The response variable was the self-perception of noise, investigated by the question: "In your neighborhood, does the noise bother you?" The explanatory variables were grouped into the following domains: sociodemographic, social determinants, self-rated health, and self-reported diseases. Results: The prevalence of noise annoyance was 47% for women and 39.8% for men. For both genders, noise annoyance was independently associated with bad traffic and the presence of loud music, discussions, and late-night parties. Conclusion: Gender differences were identified in the association of noise annoyance with sociodemographic characteristics and self-reported morbidity. Traffic and social customs were the main sources of noise in the regions under study.

RESUMO Objetivo: Analisar a associação entre o incômodo provocado pelo ruído com fatores individuais e sociodemográficos e a autopercepção de vizinhança em um centro urbano. Métodos: Os dados foram coletados por meio de um estudo transversal de base populacional, desenvolvido em dois dos nove distritos sanitários do município de Belo Horizonte, Minas Gerais, no período de 2008 a 2009. Participaram do estudo 3.934 indivíduos, de ambos os sexos, com 18 anos ou mais. A variável resposta foi a autopercepção do ruído, investigada pela pergunta: "Pensando na sua vizinhança o ruído/barulho incomoda você?". As variáveis explicativas foram agrupadas nos seguintes domínios: sociodemográfico, determinantes sociais, autoavaliação de saúde e autorrelato de doenças. Resultados: Para as mulheres, a prevalência do incômodo ao ruído foi de 47%, e para os homens, foi de 39,8%. Para ambos os sexos, o incômodo ao ruído foi independentemente associado ao trânsito ruim e presença de música alta, discussões e festas até tarde. Conclusões: Diferenças entre os sexos foram observadas para associação entre o incômodo ao ruído, características sociodemográficas e morbidade autorreferida. O trânsito e os costumes sociais se configuraram como a principal fonte geradora de ruído nas regiões estudadas.

Spatial-temporal analysis of leprosy in a priority Brazilian northeast municipality for disease control / Análisis espacio-temporal de la lepra en municipio del noreste brasileño prioritario para el control de la enfermedad / Análise espaço-temporal da hanseníase em município do Nordeste brasileiro prioritário para o controle da doença

ABSTRACT Objectives: to analyze the spatial-temporal distribution of leprosy in a priority municipality for leprosy control. Methods: ecological study, conducted in a city in the Northeast of Brazil, whose analysis units were census sectors. The study used compulsory notification data for cases registered between 2008 and 2017. TerraView software and the Batch Geocode tool was used for geocoding. The detection of spatial-temporal agglomerations of high relative risks was done by scanning statistics. Results: the spatial-temporal distribution of cases was heterogeneous, creating four agglomerations of high relative risks in the urban area of the municipality between the years 2008 and 2012; and annual prevalence rates classified from high to hyperendemic. Conclusions: areas of higher risk and concentration of the disease in space-time were linked to the characteristics of high population density and social vulnerability of these spaces, raising the prioritization of health professionals' actions, systems, and services for control, and monitoring the disease.
