Resumo O objetivo deste artigo é investigar se a dificuldade em tomar medicamentos está associada ao acidente vascular encefálico (AVE) entre idosos com hipertensão arterial sistêmica (HAS) e explorar esta associação com arranjos familiares. Estudo seccional baseado em 3.502 idosos com HAS dos quatro polos do Estudo Fibra, Brasil, incluindo 14 cidades das cinco regiões brasileiras. Foi usado o diagnóstico médico de AVE e a dificuldade em tomar medicamentos (dificuldade autorrelatada e dificuldade financeira). Utilizou-se a regressão logística na análise multivariada. Diferentemente das mulheres, homens com HAS que relataram dificuldade em tomar medicamentos (não adesão não intencional) apresentam maior chance de ter AVE. Quando estratificado por arranjos familiares, homens que moravam com o cônjuge apresentaram chance ainda maior de ter AVE, quando comparados com aqueles sem dificuldade em tomar medicamentos e que vivem sozinhos. Nenhuma associação foi encontrada para dificuldade financeira, tanto para mulheres quanto para homens. Dificuldades não intencionais em tomar medicamentos têm um papel importante no controle da HAS entre homens. Estratégias de controle da pressão arterial realizadas na atenção primária não devem focar apenas nos pacientes, mas nos cônjuges destes pacientes.

Abstract This article aims to investigate whether difficulty in taking medication is associated with stroke among older adults with Systemic Arterial Hypertension (SAH) and to explore their association with living arrangements. Cross-sectional study was based on 3,502 older adults with SAH from the four universities pole of Frailty in Brazilian Older People (Fibra) Study, Brazil, including 14 municipalities of the five Brazilian regions. We used the medical diagnosis of stroke and difficulty in taking medications (self-reported difficulty and financial difficulty affording prescribed medications). Multivariate analysis was performed using logistic regression. Differently from women, older men with SAH, which report difficulty in taking medication (unintentional non-adherence), have higher odds of stroke. When stratified by living arrangements, those living with a partner have even higher odds of stroke compared to those without difficulty in taking medication and living alone. None association was found for difficulty affording prescribed medication for both men and women. Unintentional difficulty in taking medication plays a role in SAH treatment among men. Primary care strategies for controlling blood pressure should not be focus only on patients but targeting spouses as well.

ABSTRACT OBJECTIVE To investigate the risk of mortality associated with sarcopenic obesity (SO), obesity (OB), and sarcopenia in elderlies. METHODS We analyzed longitudinal data from 270 participants > 65 years of age of Phase III of the Study on Frailty in Brazilian Older People (FIBRA–RJ–2012). Socioeconomic, demographic, lifestyle, morbidity, and functional data were collected by home based interviews. DXA and body composition assessment was conducted in a laboratory. In women, OB was diagnosed when body fat percentage ≥ 38% and sarcopenia by an Appendicular Lean Mass Index (ALMI) < 6.00 kg/m2 and muscle strength < 16 Kgf. In men, OB was diagnosed when body fat percentage ≥ 27%, and sarcopenia was diagnosed with ALMI < 7.00 kg/m2 and muscle strength < 27 Kgf. SO was assessed by combining variables used to diagnose obesity and sarcopenia. The probabilistic linkage method was used to obtain deaths in the 2012-January 2017 period from the Brazilian Mortality Registry. Cox regression models were tested, and crude and adjusted hazard ratio calculations were conducted. RESULTS After adjusting for sex, age, race/skin color, walking as an exercise, and hypertension, individuals with sarcopenia were 5.7 times more likely to die (95%CI: 1.17–27.99) than others without sarcopenia and obesity. CONCLUSION A high risk of death was observed in individuals with sarcopenia. These results show the need for preventive strategies of early detection and treatment in order to increase survival employing multimodal interventions.

Abstract This article aims to categorize elderly non-frail (NF), pre-frail (PF) and frail (FF) as to fast and slow gait speed. Compare NF, PF and FF, and analyze associations between fast or slow gait speed with clinical, functional and mental factors. 5,501 elderly (65 years or over; to the Frailty in Brazilian Older People Study), classified as NF, PF and FF (Fried´s frailty phenotype) and, in relation to fast gait speed (≥ 0.8m/s) and slow (< 0.8m/s). Age, sex, body mass index, muscular strength, advanced, instrumental and basic activities of daily living, falls, fear of falling and depressive symptoms were evaluated. Logistic regression analysis investigated associations between variables. The proportion of the slow elderly increased with fragility (NF = 12.39%, PF = 37.56%, FF = 88.83%, p < 0.01). Be woman, performance in activities of daily living, muscle strength and fall were associated with fragility syndrome. The association between frailty and adverse health outcomes reinforces its primacy as an indicator of the functional health of the elderly. Functional capacity, muscular strength, and falls should be evaluated considering their potential for reversibility.

Resumo O estudo objetivou subsidiar metodologicamente a análise socioambiental espacial de bacias hidrográficas, a partir do uso de dados secundários sociais, econômicos e ambientais na bacia hidrográfica do rio Una, Ibiúna, São Paulo. Realizou-se a triagem de dados secundários, analisados por meio da correlação de Pearson, da regressão linear múltipla e do indicador de qualidade socioambiental espacializado. Houve forte correlação entre as características econômicas dos domicílios e de seus ocupantes com o saneamento ambiental. O índice de qualidade revelou melhores condições socioambientais na zona urbana, contribuindo para a identificação de áreas com necessidade de intervenção que incluem a área rural, por trata-se de locais com relevantes interesses sociais, econômicos e de conservação dos recursos hidricos.

Abstract The study aimed to methodologically subsidize the socioenvironmental analysis of river basins, based on the use of secondary social, economic and environmental data in the Una river basin, Ibiúna, São Paulo, Brasil. Secondary data were screened, using Pearson’s correlation, multiple linear regression, and a spatial socio-environmental quality index. There was a strong correlation between the economic characteristics of households and their occupants with environmental sanitation. The quality index revealed better socio-environmental conditions in the urban area, contributing to the identification of areas requiring intervention that include the rural area, because these are sites with relevant social, economic and conservation interests of water resources.

OBJECTIVES: To assess the prevalence of sarcopenic obesity and its association with functionality, lifestyle, biomarkers, and morbidities in older adults. METHODS: The study analyzed cross-sectional data from 270 older adults who participated in phase III of the Frailty in Brazilian Older People Study (Fragilidade em Idosos Brasileiros—Rio de Janeiro, FIBRA-RJ study-2013). They took part in a home interview surveying socioeconomic, demographic, lifestyle, morbidities, and functional data. Blood was collected for biochemical marker analysis and participants’ body composition was determined by dual-energy X-ray absorptiometry. For women, the diagnosis of sarcopenic obesity was defined at a body fat percentage ≥38% and appendicular skeletal muscle mass index (ASMMI) <5.45 kg/m2. For men, a fat percentage ≥27% and ASMMI <7.26 kg/m2 was defined as sarcopenic obesity. Multivariate analysis was performed using a multinomial regression model (95% confidence intervals), with sarcopenic obesity as the outcome. RESULTS: The prevalence of sarcopenic obesity was 29.3%. In the final fitted model, the variables that displayed statistically significant association with sarcopenic obesity were lower gait speed, self-reported medical diagnosis of arthrosis or arthritis, and high levels of glycemia. CONCLUSION: The study showed a high prevalence of sarcopenic obesity in non-institutionalized older adults in Brazil. The finding that this condition was associated with modifiable risk factors may provide insights into measures directed at prevention and reduction of the risk of sarcopenic obesity in this population subgroup.

ABSTRACT OBJECTIVE To evaluate the incidence and persistence of fear of falling in older adults and the clinical/functional, psychosocial and lifestyle-related risk factors. METHODS A longitudinal study with 393 community-dwelling older adults aged 65 years and over (110 men/ 283 women) resident in the North Zone of the city of Rio de Janeiro, Brazil. The fear of falling was assessed by the Falls Efficacy Scale-I-BR. The explanatory variables assessed were: number of comorbidities and medicines, history of falls, fracture from falling, use of walking aids, functional dependence in basic and instrumental activities of daily living, hearing and visual impairment, hand grip strength, walking speed, self-rated health, body mass index, depressive symptoms, cognitive impairment, living alone and activity level. Incidence, persistence and risk factors were estimated. Multivariate analysis was performed using Poisson Regression, obtaining relative risks (RR) and corresponding to 95% confidence intervals. RESULTS Among the 393 participants, fear of falling occurred in 33.5% and was persistent in 71.3%. Incidence was found to associate with using seven or more medicines and reporting worse activity level than the prior year. Risk factors for persistent fear were: using seven or more medicines, a history of one or two falls, reduced walking speed, hearing impairment, cognitive impairment, depressive symptoms and poor or very poor self-rated health. CONCLUSION Fear of falling is a frequent and persistent condition. Many factors related to persistent fear showed no association with the incidence of fear, emphasizing the need for focused strategies to reduce risk factors that may be associated with the chronification of fear of falling.

Resumo As interferências antrópicas sempre provocaram grandes impactos na superfície terrestre, com maior intensidade nos últimos tempos em função das mudanças do uso da terra, que contribuem para emissão dos gases do efeito estufa, em especial do dióxido de carbono. Neste sentido, o estudo objetivou analisar as transições do uso da terra e as emissões de CO2 resultantes dessas ações em uma bacia hidrográfica. Para isto realizou-se mapeamentos de uso da terra de 2007, 2010, 2013 e 2016, como também estimou as emissões decorrentes das transições. Para o cálculo das emissões líquidas de CO2 foram utilizados dados das transições que ocorreram, da vegetação pretérita e informações pedológicas. Todos os procedimentos foram realizados com auxílio de técnicas de geoprocessamento e sensoriamento remoto, resultando em matrizes de transições e de emissões do CO2, além das informações espacializadas. Observou-se que a categoria floresta apresentou a maior conversão para outros tipos de uso da terra, destacando-se uma perda de 208,86 ha entre 2010 a 2013. Em relação as emissões, verificaram-se que em nove anos ocorreram mais emissões do que sequestro de carbono da atmosfera, o que mostra a necessidade de medidas de gestão e planejamento que visem a amenização dos impactos ocasionados pela intensa modificações de uso terra na bacia estudada.

Abstract Anthropogenic interference has always impacted the Earth's surface, with greater intensity in recent times due to land use changes, which contribute to the emission of greenhouse gases, especially carbon dioxide. In this sense, this study analyzes land use transitions and CO2 emissions resulting from these actions in a watershed. For this, land use mappings were made in 2007, 2010, 2013, and 2016, along with estimates of the emissions from transitions. The calculation of net CO2 emissions included data from the transitions that occurred, from past vegetation, and pedological information. All procedures were performed with the aid of geoprocessing and remote sensing techniques, resulting in matrices of transitions and CO2 emissions, in addition to spatialized information. The forest category showed the highest conversion to other types of land use, with a loss of 208.86 ha between 2010 and 2013. In the observed period of nine years, carbon emissions were higher than its sequestration from the atmosphere, which shows the need for management and planning to mitigate the impacts caused by intense land use changes in the studied watershed.

RESUMO A velocidade da marcha (VM) tem sido considerada um marcador de saúde em idosos capaz de predizer desfechos adversos de saúde, mas a compreensão de fatores associados a ela ainda é limitada e controversa. O objetivo deste trabalho é identificar desfechos adversos de saúde relacionados ao declínio da velocidade de marcha em idosos comunitários. Trata-se de estudo transversal e multicêntrico, que avaliou o autorrelato de doenças crônicas e de hospitalização no último ano, polifarmácia e velocidade de marcha. Utilizou-se análise de regressão logística para estimar os efeitos de cada variável independente na chance de os idosos apresentarem declínio na velocidade de marcha inferior (VM<0,8m/s) (α=0,05). Participaram da pesquisa 5.501 idosos. A menor velocidade da marcha mostrou-se associada a portadores de doenças cardíacas (OR=2,06; IC: 1,67-2,54), respiratórias (OR=3,25; IC: 2,02-5,29), reumáticas (OR=2,16; IC: 1,79-2,52) e/ou depressão (OR=2,51; IC: 2,10-3,14), hospitalizados no último ano (OR=1,51; IC: 1,21-1,85) e polifarmácia (OR=2,14; IC: 1,80-2,54). Assim, os resultados indicaram que idosos com velocidade de marcha menor que 0,8m/s apresentam maior risco de eventos adversos de saúde. Dessa forma, sugere-se que a velocidade de marcha não seja negligenciada na avaliação de idosos comunitários, inclusive na atenção básica.

Abstract Gait speed (GS) can predict adverse health outcomes. However, an understanding of its associated factors is still limited and with some controversy. The objective of this study was to identify adverse health outcomes related to the decline in gait speed in community-dwelling older adults. This is a cross-sectional study that evaluated records of chronic diseases and hospitalization in the last year, polypharmacy, and gait speed. Logistic regression analysis was used to estimate the effects of each independent variable on the chance of older adults presenting a decline in gait speed (GS<0.8 m/s) (α=5%). In total, 5,501 older adults participated. Brazilian older adults with heart diseases (OR=2.06; 1.67-2.54 CI), respiratory diseases (OR=3.25; 2.02-5.29 CI), rheumatic (OR=2.16; 1.79-2.52 CI) and/ or depression diseases (OR=2.51; 2.10-3.14 CI); hospitalized in the last year (OR=1.51; 1.21-1.85 CI) and under polypharmacy (OR=2.14; 1.80-2.54 CI) were associated with lower gait speed. Thus, the results showed that those with gait speed lower than 0.8 m/s are at higher risk of some adverse health events. Therefore, it is suggested that gait speed should not be neglected in the evaluation in community-dwelling older adults, including basic health care.

RESUMEN La velocidad de la marcha (VM) se ha considerado un marcador de salud en los ancianos capaz de predecir resultados adversos en la salud, pero la comprensión de sus factores asociados todavía es limitada y controvertida. El presente estudio tiene como objetivo identificar los resultados adversos para la salud relacionados con la disminución de la velocidad de la marcha en los ancianos comunitarios. Se trata de un estudio transversal y multicéntrico, el que evaluó el autoinforme de enfermedades crónicas y de la hospitalización en el último año, la polifarmacia y la velocidad de la marcha. Se utilizó el análisis de regresión logística para estimar los efectos de cada variable independiente sobre la posibilidad de que los ancianos presenten una disminución más baja en la velocidad de la marcha (VM<0,8 m/s) (α=0,05). Participaron en el estudio 5.501 ancianos. La velocidad de marcha más baja estuvo asociada a portadores de enfermedades cardíacas (OR=2,06; IC: 1,67-2,54), respiratorias (OR=3,25; IC: 2,02-5,29), reumáticas (OR=2,16; IC: 1,79-2,52) y/o depresión (OR=2,51; IC: 2,10-3,14), hospitalizados en el último año (OR=1,51; IC: 1,21-1,85) y polifarmacia (OR=2,14; IC: 1,80-2,54). De esta manera, los resultados indicaron que los ancianos con velocidades de marcha por debajo de 0,8m/s presentan un mayor riesgo de eventos adversos para la salud. Por lo tanto, se sugiere que la velocidad de la marcha no debe ser descuidada en la evaluación de ancianos comunitarios, incluso en la atención primaria.

Marco contextual: Los instrumentos para evaluar la capacidad funcional de los ancianos, como el Functional Activities Questionnaire, pueden utilizarse para detener y predecir la demencia. Objetivo: Evaluar la precisión de la versión brasileña del Functional Activities Questionnaire (FAQ-BR) en el seguimiento de la demencia. Metodología: Estudio transversal realizado con 265 ancianos y sus respectivos informantes. El rendimiento del FAQ-BR se comparó con el diagnóstico clínico de demencia y su puntuación con la de los instrumentos de seguimiento del deterioro cognitivo/demencia. La curva de característica operativa del receptor (ROC, en inglés) se utilizó para determinar la sensibilidad y especificidad del mejor punto de corte. Resultados: El área bajo la curva ROC indicó una precisión del 79,7% con punto de corte = 14, que mostró sensibilidad máxima (80,0%) y especificidad (72,0%). La puntuación del FAQ-BR mostró altas correlaciones con las puntuaciones de los instrumentos de seguimiento del deterioro cognitivo/demencia. Conclusión: En el área bajo la curva ROC, la sensibilidad y la especificidad del FAQ-BR resultaron ser inapropiadas, por lo que no se pudo recomendar su uso en el seguimiento de la demencia.

Resultados: A área sob a curva ROC indicou acurácia de 79,7% com ponto de corte = 14, que mostrou as máximas sensibilidade (80,0%) e especificidade (72,0%). A pontuação do FAQ-BR apresentou correlações altas com as pontuações dos instrumentos de rastreio de declínio cognitivo/demência. Conclusão: A área sob a curva ROC, a sensibilidade e a especificidade do FAQ-BR mostraram-se inapropriadas, não permitindo recomendar o seu uso no rastreio de demência.

Background: Instruments for measuring functional disability of the elderly, such as the Functional Activities Questionnaire, can be used for the detection and prediction of dementia. Objective: To evaluate the accuracy of the Brazilian version of the Functional Activities Questionnaire (FAQ-BR) in dementia screening. Methodology: Cross-sectional study with 265 elderly and their respective informants. The performance of the FAQ-BR was compared to the clinical diagnosis of dementia and their score compared to screening instruments for cognitive decline/dementia. The receiver operating curve (ROC curve) was used to determine the sensitivity and specificity of the best cutoff. Results: The area under the ROC curve indicated an accuracy of 79.7% with cutoff point = 14, which showed the highest sensitivity (80.0%) and specificity (72.0%). The FAQ-BR score showed high correlations with the scores of the cognitive decline/dementia screening instruments. Conclusion: The area under the ROC curve, sensitivity and specificity of the FAQ-BR were found to be inappropriate, and it was not possible to recommend its use in dementia screening.

Resumo Fragilidade é um estado de vulnerabilidade fisiológica multissistêmica relacionada à idade e a um risco aumentado de desfechos adversos. O objetivo do presente estudo foi avaliar a prevalência e os fatores associados à fragilidade no estudo FIBRA em Minas Gerais, Brasil. Selecionou-se uma amostra aleatória, estratificada por unidade territorial, sexo e idade, de 461 indivíduos, com 65 anos ou mais. A fragilidade foi estabelecida pela presença de três ou mais de cinco itens: sensação de exaustão, baixa força de preensão manual, velocidade da marcha lenta, perda de peso e baixo gasto calórico. A média de idade foi de 74,4 anos (DP± 6,8), 69,6% eram mulheres e 71,9% brancos. A prevalência de fragilidade foi de 5,2%; 49,9% foram de indivíduos pré-frágeis. Idade avançada (OR: 6,4; IC 1,76-23,8), comprometimento das atividades básicas de vida diária (OR: 5,2; IC 1,1-23,1) e auto percepção de saúde ruim (OR: 0,13; IC 0,03-0,4), foram associados à fragilidade. No presente estudo, um número substancial de indivíduos apresentou-se frágil, enquanto que metade da amostra estava sob risco de progressão para esta condição, sugerindo que é urgente a adoção de medidas de saúde pública com objetivo de prevenção e redução de complicações.

Abstract Frailty is a state of multisystem physiological vulnerability related to aging and an increased risk of adverse outcomes. This study aimed to evaluate the prevalence and associated factors of frailty in the Fibra-JF Study, Minas Gerais, Brazil. We selected a random sample of 461 individuals aged 65 years or more stratified by territorial unit, gender and age. The frailty syndrome was established by the presence of three or more of five items: a feeling of exhaustion, low handgrip strength, slow gait speed, weight loss, and low caloric expenditure. The mean age was 74.4 (SD ± 6.8) years, 69.6% were women and 71.9% white. The prevalence of frailty was 5.2%; 49.9% was from pre-frail subjects. Advanced age (OR: 6.4; CI 1.76-23.8), impairment of the basic activities of daily living (OR: 5.2, CI 1.1-23.1) and self-perception of poor health (OR: 0.13, CI 0.03-0.4) were associated with frailty. In this study, a substantial number of individuals was classified as frail, while half of the sample was at risk of progression towards this condition, suggesting that it is urgent to adopt public health measures focused on frailty prevention and reduction of associated adverse health outcomes.

OBJECTIVES: Sarcopenia is a common treatable geriatric condition. The aim of this study was to estimate the prevalence of sarcopenia and its associated factors in community-dwelling elderly living in Rio de Janeiro, Brazil, and to discuss the impact of different muscle mass, handgrip strength and gait speed cut-off values on the reported frequency of sarcopenia. METHODS: The health habits, functional capacity, and anthropometric measurements of 745 individuals aged ≥65 years from the Frailty in Brazilian Older People study were analyzed. The participants were classified into the following four groups: no sarcopenia, pre-sarcopenia, sarcopenia and severe sarcopenia. Univariate and multivariate regression analyses were performed. Muscle mass, handgrip strength and gait speed cut-off thresholds tailored to the sample and those proposed by the European Working Group on Sarcopenia in Older People were used to compare the prevalence rates of sarcopenia. RESULTS: Seventy-three percent of the participants were female, 61.9% were Caucasian, and the mean age was 76.6 years. The prevalence rates of sarcopenia were 10.8% and 18% using the sample-tailored and European consensus cut-off values, respectively. Sarcopenia was associated with advanced age (OR: 37.2; CI95%12.35-112.48), Caucasian race (OR: 1.89; CI 95% 1.02-3.52), single marital status (OR:6; CI95% 2.2-16.39), low income (OR:3.64; CI 95% 1.58-8.39), and the presence of comorbidities (OR:3.26; CI 95%1.28-8.3). CONCLUSION: In this study, the estimated prevalence of sarcopenia was similar to that reported in most studies after the tailored handgrip strength and gait speed cut-off values were adopted. A higher prevalence was observed when the cut-off values suggested by the European consensus were used. This indicates that the prevalence of sarcopenia must be estimated using population-specific reference values.
