All-cause mortality over a three-year period among community-dwelling older adults in Southern Brazil / Mortalidade por todas as causas em um período de três anos entre idosos não institucionalizados do Sul do Brasil

ABSTRACT: Objective: To evaluate all-cause mortality in approximately three years of follow-up and related sociodemographic, behavioral and health factors in community-dwelling older adults in Pelotas, RS. Methods: This was a longitudinal observational study that included 1,451 older adults (≥ 60 years) who were interviewed in 2014. Information on mortality was collected from their households in 2016-2017 and confirmed with the Epidemiological Surveillance department of the city and by documents from family members. Associations between mortality and independent variables were assessed by crude and multiple Cox regression, with hazard ratio with respective 95% confidence intervals (95%CI). Results: Almost 10% (n = 145) of the participants died during an average of 2.5 years of follow-up, with a higher frequency of deaths among males (12.9%), ?80 years (25.2%), widowhood (15.0%), no education (13.8%) and who did not work (10.5%). Factors associated with higher mortality were: being a male (HR = 2.8; 95%CI 1.9 - 4.2), age ?80 years (HR = 3.9; 95%CI 2.4 - 6.2), widowhood (HR = 2.2; 95%CI 1.4 - 3.7), physical inactivity (HR = 2.3; 95%CI 1.1 - 4..6), current smoking (HR = 2.1; 95%CI 1.2 - 3.6), hospitalizations in the previous year (HR = 2.0; 95%CI 1.2 - 3.2), depressive symptoms (HR = 2.0; 95%CI 1.2 - 3,4) and dependence for two or more daily life activities (HR = 3.1; 95%CI 1,7 - 5.7). Conclusion: The identification of factors that increased the risk of early death makes it possible to improve public policies aimed at controlling the modifiable risk factors that can lead to aging with a better quality of life.

RESUMO: Objetivo: Avaliar a mortalidade por todas as causas em aproximadamente três anos de acompanhamento e os fatores sociodemográficos, comportamentais e de saúde em idosos comunitários de Pelotas, Rio Grande do Sul. Métodos: Foi um estudo observacional longitudinal que incluiu 1.451 idosos (≥ 60 anos) entrevistados em 2014. As informações sobre mortalidade foram coletadas nos domicílios em 2016-2017, confirmadas com o setor de Vigilância Epidemiológica do município e por documentos de familiares. As associações entre mortalidade e as variáveis independentes, por regressão de Cox simples e múltipla, foram apresentadas pelos riscos relativos com os respectivos intervalos de confiança (95%). Resultados: Quase 10% (n = 145) dos participantes morreram durante uma média de 2,5 anos de acompanhamento, sendo a maior frequência de óbitos em homens (12,9%), indivíduos com ≥ 80 anos (25,2%) e viúvos (15,0%). Estiveram associadas ao maior risco de mortalidade: sexo masculino (RR = 2,8; IC95% 1,9 - 4,2), ≥ 80 anos (RR = 3,9; IC95% 2,4 - 6,2), viuvez (RR = 2,2; IC95% 1,4 - 3,7), inatividade física (RR = 2,3; IC95% 1,1 - 4,6), tabagismo atual (RR = 2,1; IC95% 1,2 - 3,8), hospitalização no último ano (RR = 2,0; IC95% 1,2 - 3,2), sintomas depressivos (RR = 2,1; IC95% 1,2 - 3,6) e dependência para duas ou mais atividades diárias (RR = 3,1; IC95% 1,7 - 5,7). Conclusão: A identificação dos fatores que aumentaram o risco de óbito precocemente possibilita melhorar políticas públicas que visem controlar os fatores de risco modificáveis para um envelhecimento com melhor qualidade de vida.

Prediction of 11-year incidence of psychophysically dependent status or death among community-dwelling younger elderlies: from an age-specified community-based cohort study (the NISSIN project)

BACKGROUND@#Predicting adverse health events and implementing preventative measures are a necessary challenge. It is important for healthcare planners and policymakers to allocate the limited resource to high-risk persons. Prediction is also important for older individuals, their family members, and clinicians to prepare mentally and financially. The aim of this study is to develop a prediction model for within 11-year dependent status requiring long-term nursing care or death in older adults for each sex.@*METHODS@#We carried out age-specified cohort study of community dwellers in Nisshin City, Japan. The older adults aged 64 years who underwent medical check-up between 1996 and 2000 were included in the study. The primary outcome was the incidence of the psychophysically dependent status or death or by the end of the year of age 75 years. Univariable logistic regression analyses were performed to assess the associations between candidate predictors and the outcome. Using the variables with p-values less than 0.1, multivariable logistic regression analyses were then performed with backward stepwise elimination to determine the final predictors for the model.@*RESULTS@#Of the 1525 female participants at baseline, 105 had an incidence of the study outcome. The final prediction model consisted of 15 variables, and the c-statistics for predicting the outcome was 0.763 (95% confidence interval [CI] 0.714-0.813). Of the 1548 male participants at baseline, 211 had incidence of the study outcome. The final prediction model consisted of 16 variables, and the c-statistics for predicting the outcome was 0.735 (95% CI 0.699-0.771).@*CONCLUSIONS@#We developed a prediction model for older adults to forecast 11-year incidence of dependent status requiring nursing care or death in each sex. The predictability was fair, but we could not evaluate the external validity of this model. It could be of some help for healthcare planners, policy makers, clinicians, older individuals, and their family members to weigh the priority of support.

Cross-sectional study of individual and environmental factors associated with life-space mobility among community-dwelling independent older people

BACKGROUND@#Life-space mobility is reflected in comprehensive longevity and health outcomes and is also an important indicator for preventing mortality and decline in well-being among older people. However, a comprehensive framework of life-space mobility and modifiable individual and environmental factors has not been well validated among community-dwelling independent older people, for primary prevention. We examined individual and environmental factors affecting life-space mobility among community-dwelling independent older people.@*METHODS@#This cross-sectional study included 3500 community-dwelling independent older people randomly selected using the National Basic Resident Registration System in Japan. Life-space mobility was measured using the Japanese version of the Life-Space Assessment (LSA) instrument, which is used to assess an individual's pattern of mobility. Negative multivariate binomial regression analysis was performed in a final sample of 1258 people. Individual factors (including physical, mental, and social characteristics) and environmental factors (including the social and material environment) were measured and analyzed as potential factors.@*RESULTS@#Negative multivariable binomial regression analysis, adjusted for demographics, showed that LSA score was associated with locomotive syndrome (β = - 0.48, 95% confidence interval [CI] = - 0.24 to - 0.73), depression (β = - 0.29, 95% CI = - 0.03 to - 0.55), health literacy (β = 0.20, 95% CI = 0.39-0.01), and participation in community activities (β = 0.23, 95% CI = 0.03-0.43) among individual factors, and receipt of social support (β = - 0.19, 95% CI = 0.00 to - 0.38) and social network (β = 0.29, 95% CI = 0.48-0.10) among environmental factors.@*CONCLUSIONS@#Our findings suggest that modifiable individual factors and environmental factors are related to life-space mobility among community-dwelling older people.

Edentulism and all-cause mortality among Brazilian older adults: 11-years follow-up

Abstract We assessed the association between edentulism and all-cause mortality among community-dwelling older adults from São Paulo, Brazil, from 2006 to 2017. This prospective cohort study used data from the Health, Well-being and Aging Study (SABE, Portuguese acronym). Edentulism was evaluated by means of clinical oral examination and all-cause mortality data were obtained from state official records. Covariates included socioeconomic factors (age, sex, and schooling); health behavior (smoking, alcohol intake, and physical activity); dental care (prostheses use); general health (multimorbidity); and nutritional status (underweight). Kaplan-Meier survival curves were stratified by edentulism and compared using the log-rank test. Cox proportional hazards model was applied to calculate hazard ratios (HRs) for the association between edentulism and mortality after adjusting for covariates. The study sample included 1,687 participants (age, 60-102 years; edentulous: 47.2%). In the 11 years of follow-up, we analyzed 10,494 person-years and 566 deaths. In bivariate analysis, edentulous older adults were found to be at a higher risk of dying from all causes than the dentate participants (HR: 1.81; 95%CI: 1.53-2.15). After sequential adjustment for socioeconomic factors, health behavior, dental care, general health, and nutritional status, this association was attenuated, but remained significant (HR: 1.34; 95%CI: 1.10-1.63). In conclusion, edentulism is a significant predictor of all-cause mortality among older adults.

Association between high psychological distress and poor oral health-related quality of life (OHQoL) in Japanese community-dwelling people: the Nagasaki Islands Study

BACKGROUND@#We investigated the association between psychological distress and oral health status/oral health-related quality of life (OHQoL) in Japanese community-dwelling people.@*METHODS@#We conducted a cross-sectional study using data from the Nagasaki Islands Study. A total of 1183 (455 men and 728 women) has been analyzed in this study. Psychological distress was measured using the Kessler Psychological Distress Scale (K6). Oral health status was measured by dental examination. The OHQoL was measured using the General Oral Health Assessment Index (GOHAI). We defined the total score of ≥5 points on the K6 as high psychological distress (high-K6 group).@*RESULTS@#The multiple linear regression analysis to identify the GOHAI showed that gender, K6, the total number of teeth, the number of dental caries, and visiting a dental clinic within the past 6 months significantly associated with the GOHAI. Among all of these variables, high-K6 (≥ 5) was a substantial contributing factor of the GOHAI (β = - 0.23, 95% Cl - 2.31 to -1.41, p < 0.0001).@*CONCLUSIONS@#It is likely that the individual with high psychological distress was strongly related to poor OHQoL even in the general population.

A nationwide study on prevalence and factors associated with dynapenia in older adults: ELSI-Brazil / Estudo nacional sobre prevalência da dinapenia e fatores associados em idosos: ELSI-Brasil / Estudio nacional sobre prevalencia de la dinapenia y factores asociados en ancianos: ELSI-Brasil

This study aimed to assess the prevalence and factors associated with dynapenia in a nationally representative sample of Brazilians aged 50 years and older. A cross-sectional study was performed with baseline data from the Brazilian Longitudinal Study of Aging (ELSI-Brazil). Dynapenia was defined as low muscle strength (< 27kg for men and < 16kg for women). Explanatory variables were sociodemographic characteristics, health conditions, health behaviors and physical performance. Analyses were based on multivariate logistic regression and population attributable fractions. Among the 8,396 participants, the prevalence of dynapenia was 17.2% (16.6% among men and 17.7% among women); for those aged 65 years and older, the prevalence was 28.2% (29.1% and 27.5% among men and women, respectively). Dynapenia was positively associated with age, low gait speed, limitations in performing two or more basic daily activities, falls and self-reported chronic diseases; and negatively associated with education level, physical activity and body mass index (overweight/obese, OR = 0.26). Prevalence of dynapenia is high in Brazilian older adults. Educational skills and physical activity improvement present greater potential to reduce dynapenia in this population.

O estudo teve como objetivo avaliar a prevalência da dinapenia e fatores associados em uma amostra nacional representativa de indivíduos com 50 anos ou mais no Brasil. Foi realizado um estudo transversal. O presente estudo usou dados da linha de base do Estudo Longitudinal da Saúde dos Idosos Brasileiros (ELSI-Brasil). A variável dependente era dinapenia, definida como baixa força muscular (< 27kg para homens e < 16kg para mulheres). Foram incluídas como covariáveis no modelo logístico, as características sociodemográficas estado de saúde, comportamentos relacionados à saúde e desempenho físico. Foram calculadas frações atribuíveis populacionais para os fatores que demonstrassem associação significativa com o desfecho. Foram estudados 8.386 participantes com 50 anos ou mais (53,3% do sexo feminino). A prevalência da dinapenia foi 17,2%, sendo 16,6% nos homens e 17,7% nas mulheres. Entre os indivíduos com 65 anos ou mais, a prevalência foi 28,2% (29,1% nos homens e 27,5% nas mulheres). A presença da dinapenia mostrou associação positiva com idade, velocidade de marcha reduzida, limitação autorrelatada em duas ou mais atividades básicas da vida diária, gênero, quedas, hospitalizações e doenças crônicas. A dinapenia mostrou associação negativa com escolaridade, atividade física e índice de massa corporal (sobrepeso/obesidade, OR = 0,26). Aproximadamente 9% da dinapenia eram atribuíveis a riscos modificáveis. O estudo indica que a dinapenia é prevalente em brasileiros com 50 anos ou mais, e que medidas para melhorar a escolaridade e atividade física têm o maior potencial de reduzir a dinapenia nessa população.

El objetivo del estudio fue evaluar la prevalencia de la dinapenia y factores asociados en una muestra nacional representativa de individuos con 50 años o más en Brasil. Se realizó un estudio transversal. El presente estudio usó datos de referencia del Estudio Longitudinal de Salud de Ancianos Brasileños (ELSI-Brasil por sus siglas en portugués). La variable dependiente era dinapenia, definida como baja fuerza muscular (< 27kg para hombres y < 16kg para mujeres). Se incluyeron como covariables en el modelo logístico las características sociodemográficas: estado de salud, comportamientos relacionados con la salud y desempeño físico. Se calcularon fracciones atribuibles poblacionales para los factores que demostrasen asociación significativa con el resultado. Se estudiaron a 8.386 participantes con 50 años o más (53,3% del sexo femenino). La prevalencia de la dinapenia fue de un 17,2%, siendo un 16,6% en hombres y un 17,7% en mujeres. Entre los individuos con 65 años o más, la prevalencia fue de 28,2% (29,1% en los hombres y 27,5% en mujeres). La presencia de la dinapenia mostró asociación positiva con edad, velocidad de marcha reducida, limitación autoinformada en dos o más actividades básicas de la vida diaria, género, caídas, hospitalizaciones y enfermedades crónicas. La dinapenia mostró una asociación negativa con: escolaridad, actividad física e índice de masa corporal (sobrepeso/obesidad, OR = 0,26). Aproximadamente un 9% de la dinapenia era atribuible a riesgos modificables. El estudio indica que la dinapenia es prevalente en brasileños con 50 años o más, y las medidas para mejorar la escolaridad y actividad física poseen un mayor potencial para reducir la dinapenia en esa población.

Aumento da utilização de benzodiazepínicos entre idosos mais velhos: Projeto Bambuí / Increased use of benzodiazepines among older adults: Bambuí Project

RESUMO: Introdução: Os benzodiazepínicos são os psicofármacos mais utilizados globalmente, apesar dos riscos associados ao seu uso prolongado, especialmente entre os idosos. Objetivo: O estudo teve como objetivo investigar a tendência do uso de benzodiazepínicos entre idosos mais velhos (75 anos ou mais) residentes em comunidade. Métodos: Trata-se de um estudo realizado com idosos com idades entre 75 e 89 anos, integrantes da linha base (em 1997) e sobreviventes (em 2012) da coorte idosa do Projeto Bambuí. A prevalência do uso de benzodiazepínicos foi estimada separadamente para cada ano, e a comparação entre elas foi realizada por meio de regressão de Poisson com variância robusta. Resultados: A prevalência do uso de benzodiazepínicos foi maior em 2012 (33,9%) em comparação a 1997 (24,9%). Após o ajuste múltiplo, a diferença de prevalências não permaneceu significativa na população total de estudo (razão de prevalência (RP) = 1,25; intervalo de confiança de 95% (IC95%) 0,99 - 1,60), diferentemente do observado no estrato feminino (RP = 1,38; IC95% 1,04 - 1,84). O clonazepam foi o medicamento que apresentou o mais forte crescimento (RP = 4,94; IC95% 2,54 - 9,62) entre os dois anos. Conclusão: O presente estudo evidenciou um importante aumento no uso de benzodiazepínicos em uma população idosa mais velha. Esses resultados preocupam, pois são medicamentos contraindicados para idosos, especialmente se utilizados cronicamente, e estão disponíveis na relação nacional de medicamentos essenciais. Os profissionais de saúde devem estar atentos para os riscos envolvidos no seu uso por essa população.

ABSTRACT: Background: Benzodiazepines are the most widely used psychoactive drugs, despite the risks associated with their prolonged use, especially among older adults. Objective: To investigate the use of benzodiazepines among community-dwelling people aged ≥ 75 years. Methods: The study was conducted among members of the baseline (in 1997) and survivors (in 2012) of the Bambuí Project cohort. The prevalence of benzodiazepine use was estimated separately for each year, and the comparison between them was performed using the Poisson regression model with robust variance. Results: The prevalence of benzodiazepine use was higher in 2012 (33.9%) compared to 1997 (24.9%). After multiple adjustments, the difference in prevalence did not remain significant in study population (PR = 1.25; 95%CI 0.99 - 1.60), unlike that observed in the female stratum (PR = 1.38; 95%CI 1.04 - 1.84). Clonazepam was the strongest-growing drug between the two years (PR = 4.94; 95%CI 2.54 - 9.62). Conclusion: This study showed an important increase in benzodiazepine use in an older adult population. These results are concerning as these drugs are contraindicated for use in older adults, mainly if used chronically, and are available in the national list of essential medicines. Health professionals should be aware of the risks involved in its use regarding this population.

Functional independence of elderly patients who fell: a follow-up study / La independencia funcional de ancianos que sufrieron una caída: estudio de seguimiento / Independência funcional de idosos que sofreram queda: estudo de seguimento

ABSTRACT Objective: to evaluate, in emergency hospital service and at home, the functional independence of elderly people who fell. Method: longitudinal study with 151 elderly. Functional Independence Measure (FIM) was used. Statistical tests were performed with univariate and bivariate analysis. Results: mean of total FIM value in the hospital was 70.4; and at home 84.3 (p <0.001). Independence was lower in the motor domain, in "self-care", "mobility" and "locomotion" dimensions, in the two evaluations (p <0.001). Dependence reduced from 97.3% elderly in the hospital to 82.8% at home (p <0.001). There was a negative correlation between total FIM and age, number of medications, number of diseases and hospitalization time in both evaluations. Femoral and hip fractures were associated with lower total FIM values (p <0.001). Conclusion: the elderly had less independence in the hospital compared to at home, with greater impairment in the motor domain and "self-care", "mobility" and "locomotion" dimensions, in the two moments evaluated.

RESUMEN Objetivo: evaluar, en el servicio hospitalario de urgencia y en el domicilio, la independencia funcional de ancianos que sufrieron una caída. Método: estudio longitudinal con 151 ancianos. Se utilizó la Medida de la Independencia Funcional (MIF). Se realizaron pruebas estadísticas con el análisis univariado y bivariado. Resultados: el promedio de la MIF total en el hospital fue 70,4; en el domicilio fue 84,3 (p<0,001). La independencia fue menor en el dominio motor, en las dimensiones "autocuidados", "movilidad" y "locomoción", en las dos evaluaciones (p<0,001). La dependencia disminuyó del 97,3% de los ancianos, en el hospital, al 82,8%, en el domicilio (p<0,001). Se observó una correlación negativa entre la MIF total y la edad, número de medicamentos, número de enfermedades y tiempo de internación en ambas las evaluaciones. Las fracturas de fémur y cadera se asociaron a menores valores de la MIF total (p<0,001). Conclusión: los ancianos presentaron menor independencia en el hospital en comparación con el domicilio, con más compromiso en el dominio motor y las dimensiones "autocuidados", "movilidad" y "locomoción" en los dos momentos evaluados.

RESUMO Objetivo: avaliar, em serviço hospitalar de urgência e no domicílio, a independência funcional de idosos que sofreram queda. Método: estudo longitudinal com 151 idosos. Utilizou-se a Medida da Independência Funcional (MIF). Foram realizados testes estatísticos com análise univariada e bivariada. Resultados: a média da MIF total no hospital foi 70,4; e no domicílio 84,3 (p<0,001). A independência foi menor no domínio motor, nas dimensões "autocuidados", "mobilidade" e "locomoção", nas duas avaliações (p<0,001). A dependência reduziu de 97,3% idosos, no hospital, para 82,8%, no domicílio (p<0,001). Houve correlação negativa entre MIF total e idade, número de medicamentos, número de doenças e tempo de internação em ambas as avaliações. As fraturas de fêmur e quadril associaram-se a menores valores da MIF total (p<0,001). Conclusão: os idosos apresentaram menor independência no hospital em comparação ao domicílio, com maior comprometimento no domínio motor e dimensões "autocuidados", "mobilidade" e "locomoção", nos dois momentos avaliados.

Prevalence of sarcopenia and its associated factors: the impact of muscle mass, gait speed, and handgrip strength reference values on reported frequencies

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.

Prevalência e fatores associados à fragilidade em uma amostra de idosos que vivem na comunidade da cidade de Juiz de Fora, Minas Gerais, Brasil: estudo FIBRA-JF / Prevalence of frailty and associated factors in a community-dwelling older people cohort living in Juiz de Fora, Minas Gerais, Brazil: Fibra-JF Study

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.

Preditores do medo de cair em idosos portugueses na comunidade: um estudo exploratório / Predictors of the fear of falling among community-dwelling elderly Portuguese people: an exploratory study

Resumo O medo de cair é um fator de risco de queda. Também tem sido associado ao declínio funcional, diminuição da qualidade de vida e aumento do isolamento social na população idosa. Este estudo teve como objetivo analisar preditores do medo de cair em pessoas idosas portuguesas residentes na comunidade. Foi desenvolvido um estudo transversal com uma amostra de conveniência de 98 participantes (57,1% mulheres; média etária 74,07 ± 8,74 anos). O protocolo de coleta de dados incluiu um questionário sociodemográfico e de saúde, a Escala de Confiança no Equilíbrio específica para a Atividade, a Escala de Ansiedade e Depressão Hospitalar, a Escala Breve de Redes Sociais de Lubben, o Timed Up and Go, e o Teste de Sentar e Levantar Cinco Vezes. Os dados foram analisados com recurso à estatística descritiva e inferencial. Os resultados indicam que no gênero feminino (p = 0.01), a percepção de saúde física boa (p = 0.01) e moderada (p = 0.02) e os sintomas de depressão (p ≈ 0.00) são preditores do medo de cair. Controlar estes preditores é um aspecto fundamental para a promoção da independência das pessoas idosas, minimizando as consequências associadas ao medo de cair.

Abstract The fear of falling constitutes a real risk factor for falls. It has also been associated with functional decline, decreased quality of life and increased social isolation among the elderly population. This study analyzed predictors of the fear of falling in elderly Portuguese people that live in the community. A cross-sectional study with a convenience sample of 98 participants (57.1% women; mean age 74.07 ± 8.74 years) was conducted. Data were collected with a protocol which includes a questionnaire for sociodemographic and health information, the Activity Specific Balance Confidence Scale, the Hospital Anxiety and Depression Scale, the Lubben Social Network Scale-6, the Timed Up and Go, and Five Times Sit to Stand Test. Data were analyzed using descriptive and inferential statistics. The results showed that female gender (p = 0.01), the perception of good (p = 0.01) and moderate (p = 0.02) physical health and the symptoms of depression (p ≈ 0.00) are predictors of fear of falling. Controlling these predictors is a fundamental aspect for promoting the independence of elderly people minimizing the consequences that are associated with the fear of falling.

Cross-sectional study on the association between frailty and violence against community-dwelling elderly people in Brazil

ABSTRACT BACKGROUND: The physical, emotional and cognitive limitations that may be present in the aging process, coupled with family unpreparedness, may lead to greater dependence among the elderly. This favors development of frailty syndrome and greater levels of violence against the elderly. The objective here was to analyze the association between violence against the elderly and frailty; and the geographic distribution of violence against the elderly according to the presence of frailty syndrome. DESIGN AND SETTING: Cross-sectional study on 705 community-dwelling elderly people in Uberaba (MG), Brazil. METHODS: The Fried frailty phenotype and conflict tactics scale were used. Data were analyzed using descriptive statistics, the chi-square test and a logistic regression model. The intensity of the events and the relationship between clusters of violence and frailty status were assessed by means of kernel estimation. RESULTS: The adjusted analysis indicated that pre-frailty and frailty were associated with physical and verbal aggression (odds ratio, OR = 1.51; 95% confidence interval, CI: 1.04-2.19; OR = 2.12; 95% CI: 1.29-3.47), frailty was associated with physical aggression (OR = 2.48; 95% CI: 1.25-4.94) and pre-frailty and frailty were associated with verbal aggression (OR = 1.48; 95% CI: 1.03-2.15; OR = 2.15; 95% CI: 1.31-3.52), respectively. Regardless of frailty status and its relationship with violence, clusters of occurrences were larger in similar regions in the southeastern part of the municipality; but superimposition of overlays relating to aggression showed that for frail individuals the clusters were smaller than for non-frail and pre-frail individuals. CONCLUSIONS: The condition of frailty was associated with greater chances of violence against the elderly.

Prevalência e fatores associados à sarcopenia, dinapenia e sarcodinapenia em idosos residentes no Município de São Paulo - Estudo SABE / Prevalence and associated factors of sarcopenia, dynapenia, and sarcodynapenia in community-dwelling elderly in São Paulo - SABE Study

RESUMO: Objetivo: Estimar a prevalência e os fatores associados à sarcopenia, dinapenia e sarcodinapenia em idosos residentes no município de São Paulo. Métodos: Estudo transversal de base populacional envolvendo 1.168 idosos pertencentes à terceira onda do Estudo SABE (Saúde, Bem-Estar e Envelhecimento), em 2010. Foramconsiderados sarcopênicos os idosos com índice de massa muscular esquelética ≤ 8,90 kg/m2 para homens e ≤6,37 kg/m2 para mulheres, dinapênicos aqueles com força de preensão manual < 30 kg para homens e < 20kg para mulheres, e sarcodinapênicos aqueles que apresentavam sarcopenia associada à dinapenia. Características sociodemográficas, comportamentais, condições clínicas, nutricionais e bioquímicas foram consideradas para determinar os fatores associados a cada uma das três condições por meio de regressão logística multinomial. Resultados: A prevalência de sarcopenia, dinapenia e sarcodinapenia foi, respectivamente, 4,8% (IC95% 3,6-6,3), 30,9% (IC95% 27,5-34,6) e 9,0% (IC95% 7,2-11,3). O avanço da idade e a desnutrição foram associados às três condições analisadas. O prejuízo cognitivo foi associado à dinapenia e à sarcodinapenia. A escolaridade, ter o hábito de fumar e não ter vida conjugal foram associados à sarcopenia, enquanto osteoartrite, escolaridade, ser ex-fumante e apresentar valores baixos de hemoglobina foram associados à dinapenia. Foram associados à sarcodinapenia o hábito de fumar e o risco de desnutrição. Conclusão: Dinapenia é a condição mais prevalente na população idosa, seguida pela sarcodinapenia e sarcopenia. Exceto por idade, escolaridade e desnutrição, os fatores associados à sarcopenia e à dinapenia são distintos. Entretanto, há similaridades em algumas associações quando se trata da presença de sarcodinapenia.

ABSTRACT: Objectives: To estimate the prevalence of sarcopenia, dynapenia, and sarcodynapenia and associated factors in older adults in the city of São Paulo, Brazil. Methods: A population-based, cross-sectional study was conducted with 1,168 older adults who participated in the third wave of the Health, Well-being, and Aging study in 2010 (SABE study). Men and women with skeletal muscle mass ≤ 8.90 and ≤ 6.37 kg/m2, respectively, were considered sarcopenic. Men and women with grip strength < 30 and < 20 kg, respectively, were considered dynapenic. Those with both conditions were considered sarcodynapenic. Sociodemographic, behavioral, clinical, nutritional, and biochemical characteristics were investigated as factors associated with each of the three conditions using multinomial logistic regression. Results: Theprevalence of sarcopenia, dynapenia, and sarcodynapenia was 4.8% (95%CI 3.6 - 6.3), 30.9% (95%CI 27.5 - 34.6) and 9.0% (95%CI 7.2-11.3), respectively. An increase in age and malnutrition was associated with all the three conditions. Cognitive impairment was associated with both dynapenia and sarcodynapenia. Schooling, current smoking habit, and not having a marital life were associated with sarcopenia. Osteoarthritis, schooling, being an ex-smoker, and low hemoglobin were associated with dynapenia. Smoking habit and the risk of malnutrition were associated with sarcodynapenia. Conclusion: Dynapenia is more prevalent among older adults, followed by sarcodynapenia, and sarcopenia. With the exception of age, schooling, and malnutrition, the factors associated with sarcopenia and dynapenia are different. However, there are similarities in some associations regarding the presence of sarcodynapenia.

Perfil de saúde bucal de idosos não institucionalizados e sua associaçãocom autoavaliação da saúde bucal / Oral health profile among community-dwellingelderly and its association with self-rated oral health

RESUMO: Introdução: O uso de prótese e a perda dentária em idosos estão associados a impactos significativos na saúde geral e na qualidade de vida. A avaliação contínua do perfil de saúde bucal dessa população é importante para o planejamento das ações e políticas da área. Objetivo: Foram objetivos deste trabalho avaliar a prevalência de perda dentária e uso de próteses entre idosos em diferentes períodos, verificar as características sociodemográficas associadas à dentição funcional (mais de 20 dentes) e avaliar o impacto do uso de prótese e da perda dentária na autoavaliação da saúde bucal. Métodos: A amostra foi composta por pessoas de 60 anos ou mais, participantes do Estudo Saúde, Bem-Estar e Envelhecimento (SABE). A avaliação da prevalência de perda dental e uso de próteses foi feita a partir da comparação dos dados coletados nos anos de 2000, 2006 e 2010. As análises dos fatores associados à dentição funcional e autoavaliação de saúde bucal foram realizadas com base nos dados coletados no ano de 2010. A comparação do perfil de saúde bucal ao longo dos três períodos foi feita por meio de análises descritivas e comparação de intervalos de confiança. Realizou-se análise de regressão logística múltipla para avaliar os fatores associados à dentição funcional e à autoavaliação da saúde bucal. Resultados: A prevalência de perda dental e uso de próteses se manteve constante ao longo dos três anos analisados. A dentição funcional foi significativamente associada à escolaridade, sexo e cor/gênero. Idosos com necessidade de próteses e bolsa periodontal apresentaram mais chances de autoavaliação ruim. Conclusão: Não houve redução da prevalência de perda dentária e uso de próteses ao longo de dez anos na população estudada. A dentição funcional está associada a desigualdades sociodemográficas. A autoavaliação de saúde bucal está associada à necessidade de próteses.

ABSTRACT: Introduction: The use of dental prosthesis and the tooth loss in elderly people are associated with significant impact on the overall health and quality of life. Continuous assessment of oral health profile in this population is important for planning the actions and policies of the area. Objectives: The aims of this study were to assess the prevalence of tooth loss and use of dental prosthesis among the elderly people in different periods, to evaluate the association between functional dentition (20 teeth or more) and socioeconomic factors, and to evaluate the impact of tooth loss and use of dental prosthesis on self-rated oral health. Methods: Thesample consisted of people aged 60 years and older who participated in the Health, Well-Being, and Aging Study (SABE). Data from the years 2000, 2006, and 2010 were used to assess the prevalence of tooth loss and use of dental prosthesis. Analysis of the factors associated with the functional dentition and self-rated oral health was based on the data collected in 2010. Comparison of oral health profile over the 3 years was done through descriptive analysis and comparison of confidence intervals. Multiple logistic regression models were used to assess the factors associated with functional dentition and self-rated oral health. Results: The prevalence of tooth loss and use of dental prosthesis remained constant over the three periods analyzed. Functional dentition was significantly associated with education, sex, and race/gender. Individuals in need of dental prosthesis and with periodontal pocket were more likely to report poor oral health. Conclusion: There was no reduction in the prevalence of tooth loss and in the use of dental prosthesis over 10 years. Functional dentition is associated with socioeconomic inequalities. Self-rated oral health is associated with the need of dental prosthesis.

Differences in the prevalence of vitamin D deficiency and hip fractures in nursing home residents and independently living elderly

ABSTRACT Objective To compare the prevalence of vitamin D deficiency and fracture history in nursing home residents and community-dwelling elderly subjects and to explore the association of vitamin D levels with various characteristics. Materials and methods Sixty-six nursing home residents and 139 community-dwelling elderly subjects participated. Marital status, medical history, medication including vitamin D supplements, smoking, past fractures were assessed. Weight and height were measured and body mass index calculated. Serum 25-hydroxyvitamin D (25-OHD), PTH, Ca, phosphate, creatinine and eGFR were determined. Results In the nursing home residents 25-OHD was lower (17.8 nmol/l, [9.4-28.6] vs. 36.7 nmol/l, [26.9-50], p < 0.001), PTH was higher (5.6 pmol/l, [3.9-8.9] vs. 4.7 pmol/l [3.6-5.8], P = 0.003) and 25-OHD deficiency was more prevalent (65.2% [53.7-76.7] vs. 22.3% [15.4-29.2], p < 0.001) as was elevated PTH (23% [12.8-33] vs. 5.8% [2-10], p = 0.001). 25-OHD correlated negatively with PTH (institutionalized r = -0.28, p = 0.025 and community-dwelling r = -0.36, p < 0.001). Hip fractures were reported by 8% of the residents and 2% of the independent elderly. The only predictor for hip fracture was elevated PTH (OR = 7.6 (1.5-36.9), p = 0.013). Conclusion The prevalence of vitamin D deficiency and secondary hyperparathyroidism was high in the institutionalized subjects. Hip fracture risk was associated with elevated PTH and not directly with vitamin D levels or the residency status.

Características clínicas e sociais determinantes para o idoso sair de casa / Clinical characteristics and social determinants in a sample of non-homebound elderly / Características clínicas y sociales determinantes para que el anciano salga de casa

O estudo objetivou avaliar fatores sociais e de saúde envolvidos no fato de o idoso (60 anos ou mais) sair de casa. Foram entrevistados 5.898 idosos identificados por visita domiciliar, aleatoriamente selecionados em 59 cidades do Rio Grande de Sul, Brasil. A associação entre o desfecho e as variáveis independentes foi analisada de forma múltipla por meio de regressão logística. Fatores favorecedores à saída de idosos de casa: ser do sexo masculino, ser de faixa etária mais jovem, ser casado, ter artrose, realizar atividades específicas com facilidade e ter boa autopercepção de saúde. A presença de cardiopatias foi um fator negativo para sair de casa. Em face da importância da vida social na qualidade de vida e na política de envelhecimento ativo da Organização Mundial da Saúde, é fundamental considerar condições clínicas que permitem aos idosos manterem-se ativos em comunidade. Estudos como este podem auxiliar na adequação das políticas públicas para idosos, principalmente atuando em condições modificáveis, como as clínicas e funcionais.

This study aimed to assess social and clinical factors associated with the fact that older adults (≥ 60 years) go out of their homes. The study interviewed 5,898 older adults identified through home visits, randomly selected in 59 cities in the State of Rio Grande do Sul, Brazil. Multivariate logistic regression was used to assess the association between the outcome and independent variables. Factors associated with going out were being men, younger and married, presence of arthrosis, ease in performing specific activities, and good self-rated health. Heart disease was a negative factor for going out. Given the importance of social activity for quality of life and the World Health Organization policy for active aging, it is extremely important to consider clinical conditions that allow the older adults to remain active in the community. Studies like this can help to adjust public policies for the elderly, especially acting on modifiable clinical and functional conditions.

El estudio tuvo como objetivo evaluar factores (de salud y sociales) involucrados en el hecho de que las personas mayores (60 años o más) salgan de casa. Se encuestaron a 5.898 ancianos, identificados mediante visitas domiciliarias, seleccionados al azar en 59 ciudades del estado de Río Grande do Sul, Brasil. La asociación entre el desenlace y las variables independientes fue analizada mediante regresión logística. Los factores que favorecieron la salida de casa fueron: sexo masculino, edad más joven, estar casado, historia de osteoartritis, facilidad en realizar actividades específicas y buena percepción de salud. La presencia de enfermedades cardiacas fue un factor negativo para salir de casa. Conociendo la importancia de la vida social en la calidad de vida, y en la política de envejecimiento activo propuesta por la Oraganización Mundial de la Salud, es muy importante tener en cuenta las condiciones clínicas que permiten a los ancianos mantenerse activos en la comunidad; estudios como éste pueden ayudar en la adaptación de las políticas públicas para las personas mayores, trabajando principalmente en condiciones cambiantes, tales como la clínica y funcional.

Factors Affecting Mobility in Community-dwelling Older Koreans with Chronic Illnesses

PURPOSE: This descriptive study aims to describe the levels of mobility in community-dwelling older Koreans with chronic illnesses, and to examine the associations of their mobility with sleep patterns, physical activity and physical symptoms including fatigue and pain. METHODS: The participants were a total of 384 community-dwelling older adults recruited from three senior centers in Seoul, Korea. Measures included mobility assessed using 6-minute walk test (6MWT), physical activity behavior, sleep profiles, fatigue and pain. Data were collected from July to December 2012. RESULTS: The mean 6MWT distance was 212.68 meters. Over 90% of the study participants (n = 373) were classified as having impaired mobility using 400 meters as the cutoff point diagnostic criteria of normal mobility in 6MWT. The 6MWT distance was 246.68 meters for participants in their 60s, 212.32 meters for those in their 70s, and 175.54 meters for those in their 80s. Significant predictors of mobility included younger age, taking mediation, regular physical activity, female gender, higher income, higher fatigue and better perception on sleep duration, which explained 18% of the total variance of mobility. CONCLUSION: A high-risk group for mobility limitation includes low income, sedentary older men who are at risk for increased fatigue and sleep deficit. Further research should incorporate other psychological and lifestyle factors such as depression, smoking, drinking behavior, and/or obesity into the prediction model of mobility to generate specific intervention strategies for mobility enhancement recommendations for older adults.

Factores asociados con el éxito académico de los estudiantes de medicina de la Universidad de Buenos Aires

El objetivo fue identificar los factores asociados al éxito académico de los estudiantes de medicina distinguidos con diploma de honor por la Universidad de Buenos Aires. En 2011 se aplicó un cuestionario a 142 graduados con esta distinción en el 2006 que incluyó 59 preguntas sobre aspectos sociodemográficos, condiciones de vida e integración social, motivación para el estudio, capacidad de aprendizaje y estado de salud durante la carrera. En comparación con los demás alumnos, los exitosos habitaban más frecuentemente en la ciudad, provenían de escuelas medias privadas o universitarias, tenían menor necesidad de trabajar para financiarse, casi todos eran solteros y sin hijos, una proporción mayor vivía lejos de su familia, tenían más progenitores profesionales y eran financiados por ellos; nunca consideraron la salida laboral para elegir la carrera, para ellos era importante alcanzar el éxito y éste dependía principalmente del esfuerzo propio; solían manejar la ansiedad, eran sociables aunque independientes y preferían la experiencia concreta a la conceptualización abstracta para adquirir información. Con el actual sistema de ingreso, estos resultados sirven para cuantificar los mecanismos latentes de autoselección durante la carrera o en un régimen restrictivo, para seleccionar los candidatos a alcanzar el éxito académico. El análisis de los factores demográficos indica algún grado de inequidad para los estudiantes menos favorecidos socialmente. Quizás, un sistema de ingreso basado solo en las capacidades intelectuales, ayudaría a individualizar y apoyar a los mejores candidatos, independientemente de su contexto social.

The aim of this study was to identify common factors relating to the academic success of medical students who were distinguished with honors at the Buenos Aires University. In 2011, 142 graduates were surveyed; the questionnaire included 59 questions on their sociodemographic environment, living conditions and social integration, motivation to study, learning capacity and health quality during their career. Compared to other students, these distinguished students more often lived in the city, far from their families; had been educated at private or universitary high schools, their economic needs were financed by their parents, who were on the whole professionals. Most of them were single and childless. The possibility of future employment oportunities (work) did not influence their choice of a medical career, academic success was important to them and they believed that success depended largely on personal effort; they knew how to handle anxiety, were sociable but independent and preferred solid experience to abstract conceptuality in order to obtain information. Our conclusion, within the current system of candidate selection, these results serve to calculate the covert self-selection mechanisms during the career, or in a more restrictive regime, to select those likely to reach academic success due to their privileged ambience. The analysis of demographic factors indicates some degree of inequality for socially disadvantaged students. Perhaps, a selection system based only on intellectual abilities would help identify and support the best candidates regardless of their social context.

Prevalência de fragilidade e fatores associados em idosos comunitários de Belo Horizonte, Minas Gerais, Brasil: dados do estudo FIBRA / Prevalence of frailty and associated factors in community-dwelling elderly in Belo Horizonte, Minas Gerais State, Brazil: data from the FIBRA study / Prevalencia de la fragilidad y factores asociados en ancianos de una comunidad de Belo Horizonte, Minas Gerais, Brasil: datos del Estudio FIBRA

A fragilidade apresenta elevada variabilidade na prevalência e é pouco investigada em países em desenvolvimento. O objetivo deste estudo foi identificar a prevalência e fatores associados à fragilidade em idosos comunitários de Belo Horizonte, Minas Gerais, Brasil. Aspectos clínicos, funcionais e sociodemográficos foram avaliados. Foi utilizado o modelo de regressão ordinal, para verificar condições associadas à fragilidade e determinar a razão de chance (α = 0,05). A prevalência de pré-fragilidade foi 46,3% e de fragilidade de 8,7%. Os idosos pré-frágeis e frágeis apresentaram, respectivamente, maiores e crescentes razão de chances para dependência em atividades instrumentais de vida diária; restrição em atividades avançadas de vida diária; utilização de dispositivos auxiliares da marcha; comorbidades; quedas; sintomas depressivos; menor autoeficácia para prevenir quedas; hospitalização e idade avançada. Foi identificado elevado percentual de estados de fragilidade associados a maiores chances para condições adversas de saúde, especialmente as relacionadas à incapacidade.

The prevalence of frailty varies greatly and has received insufficient attention in developing countries. This study aimed to identify the prevalence of frailty and associated factors among the elderly in Belo Horizonte, Minas Gerais State, Brazil. Clinical, functional, and socio-demographic factors were analyzed. An ordinal regression model was used to verify conditions associated with frailty and to determine odds ratios ( α= 0.05). Prevalence rates were 46.3% for pre-frailty was 8.7% for weakness. Pre-frail and frail elderly, respectively, showed higher and increasing odds ratios for dependency in instrumental activities of daily living; restrictions in advanced activities of daily living; use of walking aids; comorbidities; falls; depressive symptoms; lower self-efficacy in preventing falls; hospitalization; and advanced age. The study identified a high percentage of frail states associated with higher odds of adverse health conditions, especially related to disability.

El objetivo del estudio fue identificar la prevalencia y los factores asociados a la fragilidad en ancianos que viven en una comunidad de la ciudad de Belo Horizonte, Minas Gerais, Brasil. Se evaluaron los factores clínicos, funcionales y socio-demográficos. Se utilizó un modelo de regresión ordinal, con el fin de verificar las condiciones asociadas con la fragilidad y para determinar el odds ratio (α = 0,05). La prevalencia de prefragilidad fue de un 46,3% y fragilidad un 8,7%. Los ancianos tipificados como pre-frágiles y frágiles tuvieron, respectivamente, una más alta y creciente proporción de probabilidad de dependencia, respecto a las actividades instrumentales de la vida diaria, restricciones en las actividades avanzadas de la vida diaria, además, se caracterizaban por el uso de dispositivos de asistencia al andar; comorbilidades, caídas, síntomas depresivos, baja auto-eficacia para evitar caídas, hospitalización y edad avanzada. Se identificó un alto porcentaje de los estados de fragilidad, asociada con mayores probabilidades de condiciones adversas para la salud, especialmente, las relacionadas con la incapacidad.
