Abstract BACKGROUND: Obesity is a risk factor for falls in older adults, but the effects of body fat distribution and its interaction with other factors are not well established. OBJECTIVES: To verify the occurrence of falls among older adults with and without abdominal obesity and the effects of sociodemographic, health, and behavioral variables on this outcome. DESIGN AND SETTING: A cross-sectional study in an urban area of Alcobaça, Brazil. METHODS: Men and women older than 60 years with (270) and without (184) abdominal obesity were included. Sociodemographic, health, and behavioral data were collected using validated questionnaires in Brazil. Descriptive and path analyses were performed (P < 0.05). RESULTS: The occurrence of falls was high in participants with abdominal obesity (33.0%). In both groups, a higher number of morbidities (β = 0.25, P < 0.001; β = 0.26, P = 0.002) was directly associated with a higher occurrence of falls. Among participants without abdominal obesity, a lower number of medications (β = -0.16; P = 0.04), a higher number of depressive symptoms (β = 0.15; P = 0.04), worse performance on the agility and dynamic balance tests (β = 0.37; P < 0.001), and lower functional disability for basic activities of daily living (β = -0.21; P = 0.006) were directly associated with the occurrence of falls. CONCLUSION: Adults older than 60 years with abdominal obesity have a higher prevalence of falls. Different factors were associated with the occurrence of falls in both groups.

ABSTRACT BACKGROUND: Frailty syndrome is associated with various physical, cognitive, social, economic, and environmental factors. Although frailty syndrome occurs progressively with age, prevention and treatment are possible. Reducing or eliminating risks and increasing protective factors may be potential strategies for reducing the prevalence of injuries related to frailty. One of the most effective actions is to decrease the time spent in sedentary behavior (SB) by increasing regular physical activity (PA). OBJECTIVE: To examine the hypothetical effect of substitution of the time spent in sleep or SB with an equivalent time spent performing moderate or vigorous PA on frailty syndrome in the older population. DESIGN AND SETTING: An analytical cross-sectional study conducted using exploratory methods of survey, carried out in Alcobaça city, Bahia, Brazil. METHODS: A total of 456 older adults of both sexes, aged ≥ 60 years, participated in this study. Frailty syndrome was identified according to the criteria of the Study of Osteoporotic Fractures. PA and SB were assessed using the International Physical Activity Questionnaire, and sleep was assessed using the Pittsburgh Sleep Quality Index. The effects of time substitution on these behaviors were verified using Poisson regression. RESULTS: The replacement of 60 min/day of SB (prevalence ratio, PR = 0.52; 95% confidence interval, CI: 0.28–0.96) or sleep (PR = 0.52; 95% CI: 0.27–0.98) with 60 min/day of moderate PA (MPA) was associated with a 48% reduction in the prevalence of frailty syndrome. CONCLUSIONS: Replacing the time spent sitting or sleeping with the same amount of MPA time may reduce frailty; the longer the duration of time spent in the substitution of sleep or SB with MPA, the greater the benefits.

ABSTRACT BACKGROUND: Dynapenia is characterized by mobility limitations in the older population when combined with aggravating behavioral factors that can increase the risk of morbidity and mortality. OBJECTIVE: To investigate the hypothetical effects of reallocation of time spent on sedentary behavior (SB), moderate-to-vigorous physical activity (MVPA), and sleep on dynapenia in older adults. DESIGN AND SETTING: A prospective cohort study using exploratory surveys in Alcobaça City, Bahia State, Brazil. METHODS: In total, 176 older adults (≥ 60 years) of both sexes participated in this study. Dynapenia was assessed using the handgrip strength test with cutoff points of < 27 kg for men and < 16 kg for women. MVPA and SB were assessed using the International Physical Activity Questionnaire, and sleep was assessed using the Pittsburgh Sleep Quality Index. RESULTS: Effects on reallocation were found for the shortest times, such as 10 minutes (odds ratio (OR) 0.92; 95% confidence interval (CI): 0.85–0.99); substituting MVPA with SB increased the chances of dynapenia by 58.0% (95% CI: 1.01–2.49). Analyzing the substitution of 60 minutes/day of SB with 60 minutes/day of MVPA revealed a protective effect, with a lower OR for dynapenia of 37.0% (OR 0.63; 95% CI: 0.40–0.99). The reallocation of sleep time did not significantly reduce dynapenia. CONCLUSIONS: Substituting the time spent sitting with the same amount of time spent on MVPA can reduce dynapenia, and a longer reallocation time confers greater health benefits in older adults.

RESUMO Trata-se de um estudo metodológico quantitativo para validação de um instrumento de pesquisa. O objetivo era validar os dados do dispositivo de acelerometria TrackHealth. A amostra foi composta por 30 indivíduos adultos de ambos os sexos selecionados por conveniência que atenderam aos critérios de inclusão e exclusão. Os monitores de atividade física utilizados para o protocolo de pesquisa foram o acelerômetro triaxial ActiGraph® wGT3X-BT e o acelerômetro TrackHealth (TH). O protocolo de atividades consistiu em 4 (quatro) atividades (caminhada a 4,8 e 6,4 km h1 e corrida a 9,7 e 12 km h1) realizadas em laboratório, em esteira Ibramed, com duração de 5 (cinco) minutos em cada etapa. Foi encontrada uma diferença entre os dados brutos de aceleração dos dois dispositivos, no entanto, o dispositivo TrackHealth apresentou maior sensibilidade nas velocidades de 4,8 e 6,4 km / h, e um alto nível de concordância (2,7-2,8%) nas velocidades iniciais da magnitude vetores. Porém, ainda há necessidade de melhorias no funcionamento do aparelho, para que o TrackHealth possa ser comercializado.

ABSTRACT This is a quantitative methodological study for the validation of a research instrument. It aimed to validate the data from the TrackHealth accelerometry device. The sample consisted of 30 adult individuals of both sexes selected by convenience who met the inclusion and exclusion criteria. The physical activity monitors used for the research protocol were the ActiGraph® wGT3X-BT triaxial accelerometer and the TrackHealth accelerometer (TH). The activity protocol consisted of 4 (four) activities (walking at 4.8 and 6.4 km h1 and running at 9.7 and 12 km h1) performed in the laboratory, on an Ibramed treadmill, lasting 5 (five) minutes at each stage. A difference was found between the raw acceleration data of the two devices, however the TrackHealth device showed higher sensitivity at speeds of 4.8 and 6.4 km/h, and a high level of agreement (2.7-2.8%) at the initial speeds of the magnitude vectors. However, there is still a need for improvement in the functioning of the device, so that TrackHealth can be commercialized.

RESUMO Objetivo Estimar a prevalência de sintomatologia depressiva em idosos brasileiros residentes na comunidade. Métodos Foi realizada uma revisão sistemática nas bases de dados Medline, SciELO, Web of Science, Scopus e CINAHL, sendo selecionados estudos com idosos brasileiros que identificaram a prevalência de sintomatologia depressiva. De forma independente, dois pesquisadores selecionaram os estudos, extraíram os dados e avaliaram a qualidade metodológica. A metanálise foi realizada para estimar a prevalência de sintomatologia depressiva usando um modelo de efeito aleatório. Resultados Foram identificados 176 artigos e 33 foram incluídos na revisão, que investigaram 34 prevalências, com um total de 39.431 idosos. A distribuição geográfica dos estudos indicou pesquisas em todas as regiões do Brasil. A versão curta da Escala de Depressão Geriátrica foi a mais utilizada. A prevalência estimada de sintomatologia depressiva foi de 21,0% (IC de 95%: 18,0-25,0; I2 = 98,3%). As análises de subgrupos revelaram elevada heterogeneidade em todas as categorias analisadas. A metarregressão não identificou as causas da heterogeneidade. Conclusão Apesar da heterogeneidade entre os estudos analisados, os resultados indicam a necessidade de estratégias de intervenção para reduzir a prevalência de sintomatologia depressiva.

ABSTRACT Objective To estimate the prevalence of depressive symptoms in Brazilian elderly people living in the community. Methods We searched the electronic databases Medline (PubMed), SciELO, Web of Science, Scopus and CINAHL, and also selected studies with Brazilian elderly people that identified the prevalence of depressive symptoms. Independently, two researchers selected the studies, extracted the data and assessed the methodological quality. The meta-analysis was performed to estimate the prevalence of depressive symptoms using a random effect model. Results We identified 176 articles and 33 were included in the review, which investigated 34 prevalences, with a total of 39,431 elderly people. The geographical distribution of the studies indicated researches in all regions of Brazil. The short version of the Geriatric Depression Scale was the most used. The estimated prevalence of depressive symptoms for Brazilian community-dwelling older adults was 21.0% (95% CI: 18.0-25.0, I2 = 98.3%). Subgroup analyzes revealed high heterogeneity in all categories analyzed. Meta-regression did not identify the causes of heterogeneity. Conclusion Despite the heterogeneity between the studies analyzed, the results indicate the need for intervention strategies to reduce the prevalence of depressive symptoms.

Resumo O estilo de vida moderno está associado a maior exposição ao comportamento sedentário (CS), sobretudo em idosos, entretanto, há uma carência de questionários validados para medida do CS em idosos brasileiros. Objetivou-se adaptar transculturalmente e validar a versão brasileira do questionário “Measure of Older Adults Sedentary Time” (MOST). Adotou-se para adaptação e validação os critérios de validade de conteúdo, clareza e concorrente. Responderam ao MOST adaptado e utilizaram acelerômetro ActiGraph wGT3X-BT por sete dias, 57 idosos (68,7 ± 3,5 anos). Após esse período, o MOST adaptado foi reaplicado e o acelerômetro recolhido. Realizou-se o somatório dos tempos das questões do MOST, download dos dados do acelerômetro em counts/min e reintegração dos dados brutos para counts em epochs de 60 segundos no software ActiLife 6.0. Foi utilizado o ponto de corte <100 counts/min. A relação entre CS através do MOST e acelerômetro foi verificada pela correlação de Pearson, reprodutibilidade pelo coeficiente de correlação intraclasse (CCI), consistência interna pelo alpha de Cronbach (α) e concordância pelo Bland-Altman. Adotou-se p ≤ 0,05 para significância estatística. O índice de validade de conteúdo foi de 100% e clareza 98%. O CCI foi de 0,72 (IC95%: 0,56-0,82) para o tempo total em CS pelo MOST. A correlação entre o CS do MOST e do acelerômetro foi de 0,37 (IC95%:0,13-0,58). Houve tendência de subestimação do CS pelo MOST adaptado comparado ao acelerômetro (viés de medida: 732,8 min/sem [2087,6; -3553,2 min/sem]). O questionário MOST adaptado apresenta parâmetros psicométricos adequados para avaliação do CS em idosos brasileiros.

Abstract Modern lifestyle is associated with prolonged exposure to sedentary behavior (SB), especially in older adults; however, there is a lack of validated questionnaires to measure SB in Brazilian older adults. The aim of this study was to adapt and validate the Brazilian version of the "Measure of Older Adults Sedentary Time" (MOST) questionnaire in Brazilian older adults. Content validity, clarity and concurrent validity of the adapted MOST were examined. Fifty-seven participants (68.7 ± 3.47 years) answered the adapted version of the MOST questionnaire and wore an ActiGraph wGT3X-BT accelerometer for seven days. After this period, participants answered the adapted MOST again and the accelerometer was collected. MOST answers were summed over for calculating self-reported time spent in SB. A cutoff point of < 100 counts/min was applied to accelerometer data for estimating time spent in SB. The relationship between SB estimates from MOST and accelerometer was verified by Pearson correlation, reproducibility was verified by intra-class correlation coefficient (ICC), internal consistency by Cronbach's alpha (α) and concordance by Bland-Altman. Significance was set at P <0.05. Content validity index and clarity index were 100% and 98%, respectively. ICC was 0.72 (95% CI: 0.56-0.82) for total time in SB assessed with the MOST questionnaire. The correlation between SB estimates from MOST and accelerometer data was 0.37 (95% CI: 0.13-0.58). The adapted MOST systematically underestimated SB compared to accelerometer (measurement bias: -732.8 min/week [2087.6; -3553.2 min/wk]). The adapted MOST questionnaire presents adequate validity for assessing SB in the Brazilian older adults.

Resumo Em meados do século passado, transformações na economia e sociedade brasileira somaram-se para desencadear uma rápida transição demográfica, que se caracterizou pelo aumento de idosos. Assim, presenciou-se um envelhecimento populacional, que foi acompanhado pelo aumento da incidência de doenças crônicas não transmissíveis. Alguns fatores de risco estão bem estabelecidos para o desenvolvimento das doenças crônicas não transmissíveis, como excesso de peso, consumo de tabaco e álcool, alimentação inadequada e inatividade física. Adicionalmente, o comportamento sedentário mostrou-se relacionado a importantes efeitos deletérios à saúde, como, por exemplo, diabetes mellitus tipo 2, obesidade e mortalidade.O estudo teve como objetivo investigar a associação entre tempo sentado e diabetes mellitus em idosos. Estudo transversal, realizado em 24 municípios integrantes da Superintendência Regional de Saúde de Uberaba, MG. Os indivíduos selecionados responderam um questionário estruturado e foram submetidos à avaliação antropométrica. Foram analisados 3.265 idosos. A prevalência de diabetes mellitus foi de 20,0% e a mediana de tempo sentado de 240,00 (P25º=137,14 e P75º=330,00) minutos/dia. A análise de regressão logística ajustada demonstrou que o tempo sentado superior a 330,00 minutos/dia associou-se positivamente com a diabetes mellitus (OR=1,329; IC95%: 1,040-1,700). Pode-se concluir que os idosos que ficam sentados por longos períodos diariamente apresentam maior chance de ter diabetes mellitus quando comparados com aqueles que ficam sentados por menor tempo.

Abstract By the middle of the last century, changes in the Brazilian economy and society triggered a rapid demographic transition characterized by an increased number of older adults in the population. Thus, Brazil has witnessed population aging, which was accompanied by an increased incidence of non-communicable chronic diseases. Some risk factors for the development of the chronic non-communicable diseases have been well established, such as overweight, tobacco and alcohol consumption, inadequate nutrition, and physical inactivity. Additionally, sedentary behavior has been related to significant deleterious effects on health, such as diabetes mellitus type 2, obesity and mortality. The objective of this study was to investigate the association between sitting time and diabetes mellitus in older adults. A cross-sectional study was conducted in 24 municipalities in the Regional Health Superintendence of Uberaba, MG. Selected subjects answered a structured questionnaire and underwent anthropometric assessment. A total of 3,265 elderly subjects, with a median time spent sitting of 240.00 (P25th=137.14 and P75th=330.00) minutes/day and a 20.0% prevalence of diabetes mellitus were detected. Adjusted logistic regression analysis showed that a sitting time of more than 330.00 minutes/day was positively associated with diabetes mellitus (OR=1.351, 95%CI: 1.057-1.729). It was concluded that older adults who daily sit for long periods of time have higher chances of having diabetes compared to those who sit for less time.

The aim of this study was to estimate the prevalence and factors associated with functional disability in the elderly. The cross-sectional design was used with a sample of 624 individuals, between 60 and 96 years of age. In the assessment of the elderly interviews and physical performance tests were used. In the inferential data analysis, the Poisson regression was used, p≤0.05. The prevalence of disability was 17.6% for Basic Activities of Daily Living and 46.3% for Instrumental Activities of Daily Living. Functional disability for Basic Activities of Daily Living was associated with increasing age, alcohol consumption, depressive symptoms and frailty; the Instrumental Activities of Daily Living were associated with increasing age, illiteracy, multigenerational family arrangement, hospitalization and fragility. The variables that remained in the explanatory model for the decline of functional capacity should be emphasized in proposals for public policies to promote the health of the elderly.

El objetivo fue estimar la prevalencia y los factores asociados a la discapacidad. Se utilizó diseño transversal, con muestra de 624 individuos de edades comprendidas entre 60 a 96 años. En la evaluación fueron utilizados entrevista y pruebas de rendimiento físico. En análisis de datos inferencial se utilizó regresión de Poisson, p≤0,05. La prevalencia de discapacidad fue 17,6% para las Actividades Básicas de la Vida Diaria y 46,3% en las actividades instrumentales de la vida diaria. La incapacidad funcional para Actividades Básicas de la Vida Diaria se asoció con la edad, consumo de alcohol, síntomas depresivos y fragilidad; actividades instrumentales de la vida diaria se asociaron con la edad, analfabetismo, disposición de la familia multigeneracional, hospitalización y fragilidad. Las variables que se mantuvieron en el modelo explicativo de la disminución de la capacidad funcional deben hacerse hincapié en la elaboración de políticas públicas para promover la salud de los ancianos.

O objetivo deste estudo foi analisar as características sociodemográficas, de saúde e comportamentais relacionadas a não participação das idosas nas atividades oferecidas pelo programa Proeti Saúde de Uberaba, Minas Gerais. Estudo observacional, do tipo caso controle, com pareamento 1:1, tendo amostra sido composta por 220 idosas de 60 a 80 anos. A Regressão Logística Binária foi utilizada para a identificação dos fatores sociodemográficos, de saúde e comportamentais associados ao não engajamento das não usuárias ao programa. Após análise hierarquizada o não engajamento das idosas às atividades do programa mostrou-se associada à sintomatologia depressiva, prática insuficiente de atividade física no domínio do lazer e autoeficácia reduzida para a realização de atividade física moderada ou vigorosa. As características identificadas neste estudo devem receber atenção prioritária na formulação de programas comunitários direcionados à promoção de atividade física às pessoas idosas.

The aim of this study was to examine the sociodemographic, health and behavioural characteristics related to non-participation of elderly people in activities offered by the program PROETI Health of Uberaba, Minas Gerais state. Observational study, case-control design with pairing 1:1 and sample composed of 220 elderly 60-80 years. Binary Logistic Regression was used to identify the sociodemographic, health and behavioral factors associated with non-engagement of non-users to the program. After hierarchical analysis, the non-engagement of the elderly in the program activities was associated with depressive symptoms, insufficient physical activity in the domain of leisure and reduced self-efficacy for performing moderate or vigorous physical activity. The characteristics identified in this study should receive priority attention in the formulation of community programs targeted at promoting physical activity for elderly people.

Objective: to analyze the factors related to the depressive symptoms in elderly of a community with low socio-economic indicators. Methods: epidemiological cross-sectional population-based household study. The study included 316 elderly resident of a city in Brazil's northeast Region. Data were collected in January 2011. The depressive symptoms were evaluated by means of a Geriatric Depression Scale (15-item version). The independent variable included socio-demographic factors, health state, functional limitation and life style. Crude and adjusted Poisson regression models were used in the statistical analyses. Results: the prevalence of depressive symptoms was 20 %. The adjusted regression model showed that the depressive symptoms were positively related to the female sex (PR = 2.00); marital status: single (PR = 2.73) and divorced (PR = 3.59); change for worse (PR = 2.53) or better (PR = 2.86) health state in comparison to the 12 previous months; worse health state in relation to other people of the same age (PR = 2.22); and functional limitation (PR = 1.72). There was an inverse association between the depressive symptoms and financial difficulty (PR = 0.46). Conclusions: the results suggest that socio-demographic factors, health self-assessment and functional capacity can be stronger depression determinants than morbidity and life style.

Objetivo: analizar los factores asociados a los síntomas depresivos en ancianos de una comunidad con bajos indicadores socioeconómicos. Métodos: estudio epidemiológico transversal de base poblacional y domiciliar. El estudio incluye 316 ancianos residentes en una ciudad de la región nordeste de Brasil. Los datos fueron colectados en enero de 2011. Los síntomas depresivos fueron evaluados por la Escala de Depresión Geriátrica (versión 15 ítems). Las variables independientes incluyeron factores sociodemográficos, estado de salud, limitación funcional y estilo de vida. Fueron usados modelos simples y ajustados de regresión de Poisson en los análisis estadísticos. Resultados: la prevalencia de síntomas depresivos fue de 20 %. El modelo de regresión ajustado mostró que la sintomatología depresiva fue positivamente asociada al sexo femenino (RP = 2,00), estados civiles soltero (RP = 2,73) y divorciado (RP = 3,59), mudanza para peor (RP = 2,53) o mejor (RP = 2,86) en el estado de salud comparado a 12 meses anteriores, peor estado de salud en relación a otras personas de la misma edad (RP = 2,22) y limitación funcional (RP = 1,72). Fue observada asociación inversa entre sintomatología depresiva y dificultades financieras (RP = 0,46). Conclusiones: los resultados sugieren que factores sociodemográficos, autoevaluación de la salud y capacidad funcional pueden ser determinantes más fuertes de depresión de que morbilidad y estilo de vida.

OBJETIVO: Analisar a associação entre a prática de atividade física no lazer e transtornos mentais comuns entre residentes de áreas urbanas de Feira de Santana, Bahia. MÉTODOS: Estudo epidemiológico de corte transversal com amostra representativa da população urbana de Feira de Santana, Bahia, constituída de 3.597 indivíduos com 15 anos ou mais de idade (71,4% do sexo feminino) da população urbana. Foi utilizado um questionário contendo informações sobre aspectos sociodemográficos, doenças referidas, hábitos de vida e atividades físicas no lazer. Para triagem de transtornos mentais comuns (TMC) foi utilizado o SRQ-20. Para avaliar a associação entre atividade física no lazer (ativo/inativo) e TMC foram estimadas as razões de prevalência e seus respectivos intervalos de confiança por meio de regressão logística múltipla e uso do método Delta. RESULTADOS: Encontrou-se uma frequência de 27,7% de indivíduos considerados ativos no lazer. A prevalência de TMC foi menor entre os indivíduos ativos no lazer, após o ajuste, num modelo de regressão logística múltipla, por sexo, faixa etária, renda, escolaridade, consumo abusivo de bebidas alcoólicas e tabagismo) (RP = 0.78 [0,70 - 0,87]). CONCLUSÃO: A população do município de Feira de Santana apresenta uma elevada frequência de indivíduos inativos no lazer, e essa condição estava associada a maior prevalência de TMC. As ações direcionadas à saúde mental devem priorizar programas que favoreçam o incentivo à prática de atividade física entre a população do município, considerando a associação desse comportamento com a prevenção de transtornos mentais comuns.

OBJECTIVE: To analyze the association between physical activity during leisure time and common mental disorders among residents in urban areas of Feira de Santana City, Bahia. METHODS: A cross-sectional study was conducted in a representative sample from the urban population. A sample of 3,597 individuals aged 15 years or older (71.4% female) was studied. A questionnaire gathered information about sociodemographic information, self-reported diseases, screening for mental disorders, lifestyle habits and physical activity during leisure time. To evaluate common mental disorders (CMD) the Self-Reporting Questionnaire (SRQ-20) was used. To analyze the association between leisure physical activity (active/inactive) and CMD, prevalence ratios (PR) and their respective 95% confidence intervals were estimated by using multiple logistic regression and the Delta method. RESULTS: We found a frequency of 27.7% of individuals who were active during leisure time. The prevalence of CMD was lower among those active in leisure time, after adjustment by sex, age, income, education, alcohol consumption and smoking (PR = 0.78; 95% CI0.70 to 0.87). CONCLUSION: The population of Feira de Santana city has a high frequency of individuals insufficiently active during leisure, and this condition was associated with higher prevalence of CMD. Actions directed to mental health programs must encourage physical activity among the population, considering the association of this behavior with low prevalence of common mental disorders.
