Associação entre declínio cognitivo, sintomas depressivos e do medo de cair com a velocidade da marcha confortável em idosos comunitários / Association between cognitive decline, depressive symptoms and the fear of falling with the speed gait in community-dwelling older adults

Diminuições na velocidade da marcha (VM) estão associadas a desfechos adversos na saúde física e mental em idosos. Assim, torna-se relevante identificar fatores que podem associar-se com a VM confortável em idosos, de forma a propor estratégias para prevenção de alterações na mobilidade. Objetivo: verificar a associação entre declínio cognitivo, sintomas depressivos e do medo de cair com a VM confortável em idosos comunitários. Métodos: tratou-se de um estudo transversal, com amostra probabilística, incluindo 308 idosos comunitários. O desfecho do estudo foi a VM confortável, sendo considerado como baixo desempenho VM < 0,8m/s. As variáveis preditoras foram 1) declínio cognitivo avaliado pelo Mini Exame do Estado Mental, 2) sintomas depressivos avaliados com a Escala de Depressão Geriátrica Abreviada e 3) medo de cair avaliado pela Falls Efficacy Scale ­ Brasil. Para analisar a associação entre as variáveis foi utilizada a Regressão Logística Multivariada. Resultados: idosos tiveram chances significativamente maiores de apresentar baixo desempenho na VM confortável quando apresentaram declínio cognitivo (OR: 4,67; IC95%: 1,68; 12,94), sintomas depressivos (OR: 2,90; IC95%: 1,42; 5,92) e medo de cair (OR: 4,08; IC95%: 1,72; 9,71) quando comparados aos que não tiveram essas condições. Conclusão: o declínio cognitivo, sintomas depressivos e medo de cair foram associados ao baixo desempenho na VM confortável nos idosos amostrados. Esses achados podem servir para identificação precoce dos fatores que estão associados a alterações na VM confortável, contribuindo para a proposição de estratégias públicas em saúde e no direcionamento de atividades de promoção em saúde para idosos comunitários.(AU)

Decreases in gait speed (GS) are associated with adverse outcomes in the physical and mental health of the elderly. Thus, it is relevant to identify factors that can be associated with comfortable GS in community-dwelling older adults, to propose strategies to prevent changes in mobility. Objective: To verify the association between cognitive decline, depressive symptoms, and fear of falling with comfortable GS in community-dwelling older adults. Methods: This was a cross-sectional study with a probabilistic sample, including 308 community-dwelling older adults. The study outcome was comfortable GS, being considered as low-performance MV < 0.8m/s. Predictive variables were 1) cognitive decline assessed by the Mini-Mental State Examination, 2) depressive symptoms assessed by the Abbreviated Geriatric Depression Scale, and 3) fear of falling assessed by the Falls Efficacy Scale - Brasil. Multivariate Logistic Regression was used to verify the association between the variables. Results: Community-dwelling older adults were significantly more likely to have poor performance in comfortable GS when they presented cognitive decline (OR: 4.67; 95%CI: 1.68; 12.94), depressive symptoms (OR: 2.90; 95%CI: 1 .42; 5.92), and fear of falling (OR: 4.08; 95%CI: 1.72; 9.71) when compared to those who did not have these conditions. Conclusion: Cognitive decline, depressive symptoms, and fear of falling were associated with poor performance in comfortable GS in the community-dwelling older adults sampled. These findings can serve for early identification of factors that are associated with changes in comfortable GS, contributing to the proposition of public health strategies and in directing health promotion activities for community-dwelling older adults.(AU)

Resultados: Verificou-se relação de interleucina-6 (p= 0,004), eritrócitos (p= 0,038), hemoglobina (p<0,001) e hematócrito (p= 0,002) com sarcopenia. Também observou-se que os idosos com força muscular alterada apresentaram valores mais baixos de hematócrito (p= 0,037) e mais altos de interleucina-6 (p= 0,002); e com desempenho físico alterado apresentaram valores mais baixos de leucócitos (p=0,024), hemoglobina (p<0,001), hematócrito (p= 0,007) e 25-hidroxivitamina D (p= 0,034) e mais altos de paratormônio (p= 0,018) e interleucina-6 (p= 0,002). Conclusão: Sugere-se a avaliação e acompanhamento dos níveis de interleucina-6, paratormônio, 25-hidroxivitamina D e da série vermelha do hemograma durante a prática assistencial.

Objective: To relate hematological, endocrine and immunological markers to the criteria for classifying sarcopenia in older people residents in the community. Method: Cross- sectional study, linked to the institutional research "Integrated Health Care for Older People". The study population consisted of males and females aged 60 years or more and assisted in primary health care. The research protocol included an interview and physical examination to evaluate the sarcopenia criteria. Analysis of the following were done: complete blood count, 25-hydroxyvitamin D, parathyroid hormone, insulin-like growth factor-1, interleukin-6 and C-reactive protein. Statistical analysis included the Mann-Whitney test, Pearson's chi-square test, Fisher's exact test and Odds Ratio. Results: There was a relationship between interleukin-6 (p= 0,004), erythrocytes (p= 0,038), hemoglobin (p<0,001) and hematocrit (p= 0,002) with sarcopenia. It was also observed that the older people with altered muscular strength had lower values of hematocrit (p= 0,037) and higher of interleukin-6 (p= 0,002); and with altered physical performance had lower values of leukocytes (p= 0,024), hemoglobin (p<0,001), hematocrit (p= 0,007) and 25-hydroxyvitamin D (p= 0,034) and higher levels of parathyroid hormone (p= 0,018) and interleukin-6 (p= 0,002). Conclusion: It is suggested to evaluate and monitor the levels of interleukin-6, parathyroid hormone, 25- hydroxyvitamin D and the red blood count series during care practice.

Efectividad a mediano plazo de un programa multidimensional en personas mayores en centros diurnos en Chile / Effectiveness of a multidimensional therapeutic program for aged people attending senior centers

BACKGROUND: It is imperative to have effective programs to improve or maintain the health of aged people. AIM: To evaluate the effectiveness of an intervention based on a multidimensional program in Senior centers in Chile five months after its implementation, in the domains of physical and mental health, functionality and quality of life in aged people. MATERIAL AND METHODS: Sixty participants older than 60 years completed a multidimensional program for one month that included interventions of guided physical exercises, in addition to educational and social activities. They were evaluated at baseline and one and five months after the intervention. RESULTS: After the first and fifth months, significant improvements were observed in the five times sit to stand test (5TSTS) and gait speed (WST), in addition, significant improvements were observed in literacy measured by the Short Assessment of Health Literacy for Spanish-speaking Adults (SAHLSA). At the fifth month, slight improvements were observed in the Yesavage and short Falls efficacy scales, Barthel index, Unipodal Station and EuroQol five-dimensional quality of life tests. CONCLUSIONS: A multidimensional program for aged people lasting one month, improved the physical health dimension and literacy by the fifth month of evaluation.

Insufficient physical activity and multimorbidity was associated with low physical functional performance in older adults: a cross-sectional study / Atividade física insuficiente e multimorbidade foram associadas ao baixo desempenho físico funcional em idosos: um estudo transversal

Aging, physical inactivity, and chronic disease can decrease strength and muscle mass and affect mobility and autonomy in older adults. This study aimed to analyze the prevalence and associated factors of low physical functional performance among older adults in the city of Pomerode, in southern Brazil. Methods: This is a cross-sectional population-based study with data on 733 older adults from the Study of Health in Pomerode ­ SHIP-Brazil. Low functional physical performance was defined as handgrip strength ≤ 32 kg for men or ≤ 20 kg for women and/or a Timed Up and Go test ≥ 11 seconds for men or ≥ 13 seconds for women. Associations were analyzed by multiple logistic regression. Results: The prevalence of low physical functional performance was 43.7% (42.2% among women and 45.5% among men). Low physical functional performance was associated with the 70­79 years age group (odds ratio [OR] = 2.07) and insufficient physical activity (OR = 2.73) in men, and with the 70­79 years age group (OR = 2.09) and multimorbidity (OR = 1.87) in women. In general, older age, insufficient physical activity, and multimorbidity were associated with low physical functional performance in older adults.

O envelhecimento, o sedentarismo e as doenças crônicas podem diminuir a força e a massa muscular e afetar a mobilidade e a autonomia do idoso. O objetivo deste estudo foi analisar a prevalência e os fatores associados ao baixo desempenho funcional em idosos de uma cidade de origem pomerana no sul do Brasil. Metodologia: Estudo transversal de base populacional com dados de 733 idosos do Estudo Vida e Saúde em Pomerode ­ ShipBrazil. O baixo desempenho físico funcional foi definido como a força de preensão palmar ≤ 32 kg para os homens ou ≤ 20 kg para as mulheres e(ou) timed up and go ≥ 11 segundos para os homens ou ≥ 13 segundos para as mulheres. As associações foram analisadas por regressão logística múltipla. Resultados: A prevalência de baixo desempenho físico funcional foi de 43,7% (42,2% idosas e 45,5% idosos). O baixo desempenho físico funcional foi associado à idade, 70-79 anos (OR = 2,07), e à atividade física insuficiente (OR = 2,73) nos homens; e à idade, 70­79 anos (OR = 2,09), e à presença de multimorbidade (OR = 1,87) nas mulheres. Em geral, maior idade, atividade física insuficiente e multimorbidade foram associadas ao baixo desempenho físico funcional entre os idosos.

Correlaciones entre el test de velocidad en 4 metros y el test de caminata en 6 min en enfermos respiratorios crónicos / Correlations between the 4 meter speed test and the 6-minute walking test in chronic respiratory patients

Resumen La prueba de velocidad de marcha en 4 metros (T4M) es considerada sustituto de la caminata en 6 min (TC6M) en EPOC. Sin embargo, no ha sido bien investigada en otras enfermedades respiratorias. Durante un año estudiamos pacientes que concurrieron a nuestra Unidad para realizar el TC6M midiendo la velocidad alcanzada en 4 metros, 2 h previo a realizar el TC6M. De 162 pacientes 99 eran mujeres. La edad media fue de 65 años, peso de 73 kg, talla de 158 cm, IMC 29,4 kg/m2. 36% tenían fibrosis pulmonar idiopática, 17% EPOC, GOLD IV,11% EPOC, GOLD III, 12% apnea de sueño y 12% otras enfermedades. No hubo diferencia para los distintos diagnósticos en ambos tests. La distancia media en TC6Mfue 368,5 m la velocidad: 1,01 m/s en T4M.Hubo una correlación positiva significativa entre ambos test: alto rendimiento en T4M es equivalente a un alto rendimiento en el TC6M. Hubo correlación negativa con la edad y positiva con la estatura. Al año de seguimiento 16 pacientes habían fallecido, siendo estos los que habían obtenido los más bajos rendimientos en ambos tests (T4M: 0,69 m/s y 248,1 m en TC6M) La posibilidad de sobrevida cayó a 20% en aquellos individuos que alcanzaron una velocidad inferior a 0,69 m/s. Es posible sustituir el TC6M por el T4M en pacientes con diferentes patologías respiratoria, podemos predecir la muerte por cualquier causa si un sujeto camina a una velocidad ≤ 0,69 m/s, T4M es barato y fácil de realizar en atención primaria, sirviendo como evaluación de riesgo para referir a un centro más complejo.

4-Meter Gait Speed Test (4MGST) a frailty test, is considered a surrogate for the 6-Minute Walk Test (6MWT) in COPD. However, it has not been investigated in other respiratory conditions. Over a year, we studied patients attending our Unit for evaluation with 6MWT, measuring the speed they achieved walking 4 m, 2 h before performing 6MWT. 162 patients (99 women) were studied; series' mean values were: age 65 years-old; body weight, 73 kg; height, 158 cm and BMI, 29.4 kg/m2. 36% of them had idiopathic pulmonary fibrosis, 17% GOLD IV COPD, 11% GOLD III COPD, 12% pulmonary arterial hypertension, 12% obstructive apnea-hypopnea syndrome, and 12% other conditions. ANOVA showed no difference between diagnostic categories for both test. Average score in 6MWT was 368.5 m and 1.01 m/s in 4MGST. Pearson correlation coefficient revealed significant positive correlation between results of both tests: high score in 4MGST is equivalent to high score in 6MWT. There was negative correlation with age and positive correlation with height. At one year follow-up, 16 patients had died. They obtained significantly lower scores in both tests (4MGST: 0.69 m/s and 6MWT: 248.1 m) Survival chance fell to 20% for patients walking slower than 0.69 m/s. It is possible to replace TC6M with T4M in patients with different respiratory pathologies, we can predict death for any cause if a subject walked at ≤ speed at 0.69 m/s. T4M is cheap and easy to perform in primary care, serving as a risk assessment to refer to a more complex center.

Factors associated with use of assistive walking devices among older adults in Brazil / Fatores associados ao uso de tecnologia assistiva para auxiliar na mobilidade entre idosos no Brasil

Abstract Background Walking devices and other forms of assistive technology (AT) can benefit older adults by supporting mobility and social interactions, but usage outside of high-income countries is generally low. Objective To examine the factors associated with AT use and whether AT use is associated with higher levels of social participation among older adults in Brazil. Method The 2013 Brazilian National Health Survey interviewed 23,815 individuals 60 years or older. Descriptive and logistic regression analyses were used to examine AT use, including canes and walkers, to assist with walking and social participation. Results Among older adults with mobility difficulty, 34.0% (95% CI 31.2- 36.9) reported using AT. Prevalence of the use of AT for walking increases with age: 21.4% of those 60-69 years reported using AT while 58.5% of those 90 years or older did. AT was negatively associated with participation in social activities. Conclusion Our analyses focused on older adults with mobility limitations who need appropriate transportation and environment adaptations to engage socially. Contrary to studies in more developed countries, among Brazilians, AT use is negatively associated with social interactions. The resulting confinement seems to lead to social isolation.

Resumo Introdução Os dispositivos de tecnologia assistiva (TA) podem ajudar idosos na mobilidade e nas interações sociais, mas o uso fora de países de alta renda é geralmente baixo. Objetivo Analisar os fatores associados ao uso de TA e se o uso de TA está associado a níveis mais elevados de participação social entre idosos no Brasil. Método A Pesquisa Nacional de Saúde - PNS 2013 no Brasil entrevistou 23.815 indivíduos com 60 anos ou mais. Análises descritivas e de regressão logística foram utilizadas para examinar a utilização de TA para auxiliar na mobilidade e participação social. Resultados Entre idosos com dificuldade de locomoção, 34,0% (95% IC 31,2-36,9) relataram uso de TA. A prevalência do uso de TA para se locomover aumenta com a idade: 21,4% dos 60-69 anos relataram usar TA enquanto a proporção aumenta para 58,5% entre os de 90 anos ou mais. Uso de TA está negativamente associado à participação em atividades sociais. Conclusão Entre idosos no Brasil com limitações de mobilidade que necessitam de adaptações adequadas de transporte e meio ambiente para engajar socialmente, o uso de TA foi associado negativamente às interações sociais. Esse resultado difere de estudos em países mais desenvolvidos.

Efeito do treinamento aeróbio em parâmetros cardiorrespiratórios, hemodinâmicos e autonômicos de pacientes com doença renal crônica em hemodiálise / Effect of aerobic training on cardiorespiratory, hemodynamic, and autonomic parameters of chronic kidney disease patients on hemodialysis

A doença renal crônica (DRC) é uma condição clínica de alto risco cardiovascular e os pacientes nos estágios mais avançados da doença que dependem de terapia renal substitutiva frequentemente tem prejuízo cardiorespiratório, níveis elevados de pressão arterial (uso de múltiplas medicações para controle), modulação autonômica prejudicada e graus variados de inflamação. Deste modo este estudo tem como objetivo verificar se o exercício físico aeróbio intradialítico tem impacto em modificar estas alterações. Os pacientes foram selecionados em duas unidades de hemodiálise em São Luís do Maranhão, Brasil, entre junho de 2016 e outubro de 2019, e foram alocados conforme aceitação em grupo controle (GC) e grupo exercício (GE). O GE foi submetido a treinamento aeróbio com bicicleta por um período de 12 semanas. Avaliação física antropométrica, teste de caminhada de 6 minutos (TC6m), ecocardiograma, eletrocardiograma com análise da variabilidade da frequência cardíaca e medidas laboratoriais foram realizadas incluindo interleucina 6 (IL6) antes e após 12 semanas em ambos os grupos. Trinta e um pacientes foram avaliados 15 pacientes no grupo controle (GC) e 16 pacientes no grupo exercício (GE). Após 12 semanas de treinamento houve diminuição da pressão arterial sistólica do grupo exercício em relação ao basal (129,8 ± 9,41mmHg vs 112,00 ± 12,0 mmHg p = 0,03). Não houve alterações na composição corporal e na maioria dos exames laboratoriais, exceto pelo aumento do KTV (índice de adequação de diálise) e diminuição do LDL colesterol no grupo exercício em relação ao grupo controle. No entanto, os níveis de HDL colesterol aumentaram (39,92 ± 6,1 mg/dL vs 48,00 ± 7,85 mg/dL p = 0,02) e IL6 diminuíram (4,56 ± 1,2 pg / mL vs 2,14 ± 1,0 pg / mL p = 0,02). Houve aumento da distância percorrida no teste de caminhada no grupo exercício (473,80 ± 98,6 metros vs 573,50 ± 74,22 metros p = 0,01). Na avaliação ecocardiográfica, verificou-se que no GE houve diminuição da pressão da artéria pulmonar estimada (31,38 ± 2,9 mmhg vs 24,2 ± 1,7 mmhg p = 0,001). Houve melhora na modulação autonômica no GE (RMSSD 11,7 ± 4,2 vs 18,4 ± 5,7 p=0,02), LFnu (52,9 ± 17,2 vs 32,0 ± 18,2 p=0,02) e HFnu (48,1 ± 17,2 vs 68,0 ± 18,2 p=0,01). Não foram evidenciados efeitos adversos e não houve abandono do treinamento. Baseados nestes resultados, é possível concluir que o exercício aeróbio intradialítico por 12 semanas pode melhorar parâmetros cardiorrespiratórios, hemodinâmicos e autonômicos, com boa aderência e sem eventos adversos, podendo ser usado como medida coadjuvante para melhora clínica destes pacientes.

Chronic kidney disease (CKD) is a clinical condition of high cardiovascular risk and patients in the more advanced stages of the disease who depend on renal replacement therapy often experience cardiorespiratory impairment, high blood pressure levels (use of multiple medications for control), modulation impaired autonomy and varying degrees of inflammation. Thus, this study aims to verify whether intradialytic aerobic exercise has an impact on modifying these variables. The patients were selected in two hemodialysis units in São Luís do Maranhão, Brazil, between May 2016 and October 2019, and were allocated according to acceptance in the control group (CG) and exercise group (EG). The group exercise was submitted to aerobic exercise with bicycle for a period of 12 weeks. Anthropometric physical evaluation, 6-minute walk test (6MWT), echocardiogram, electrocardiogram with analysis of heart rate variability (VFC) and laboratory measurements were performed including interleukin 6 (IL6) before and after 12 weeks in both groups. Thirty-one patients were evaluated 15 patients in the control group (CG) and 16 patients in the exercise group (EG). After 12 weeks of training, there was a decrease in systolic blood pressure in the exercise group compared to baseline (129.8 ± 9.41 mmHg vs 112.00 ± 12.0 mmhg p = 0.03). There were no changes in body composition and in most laboratory tests, except for an increase in KTV (dialysis adequacy index) and a decrease in LDL cholesterol in the exercise group compared to the control group. However, HDL cholesterol levels increased (39.92 ± 6.1 mg / dL vs 48.00 ± 7.85 mg / dL p = 0.02) and IL6 decreased (4.56 ± 1.2 pg / mL vs 2.14 ± 1.0 pg / mL p = 0.02). There was an increase in the distance covered in the walking test in the exercise group (473.80 ± 98.6 m vs 573.50 ± 74.22 m p = 0,01). In the echocardiographic evaluation, it was found that in the EG there was a decrease in the estimated pulmonary artery pressure (31.38 ± 2.9 mmhg vs 24.2 ± 1.7 mmhg p = 0.001). There was an improvement in autonomic modulation in the EG (RMSSD 11.7 ± 4.2 vs 18.4 ± 5.7 p = 0.02), LFnu (52.9 ± 17.2 vs 32.0 ± 18.2 p = 0.02) and HFnu (48.1 ± 17.2 vs 68.0 ± 18.2 p = 0.01). There were no adverse effects and training was not abandoned. Based on these results, it is possible to conclude that intradialytic aerobic exercise for 12 weeks can improve cardiorespiratory, hemodynamic, and autonomic parameters, with good adherence and without adverse events, and can be used as a supporting measure for the clinical improvement of these patients.

Síndrome de risco cognitivo motor em pessoas idosas de um serviço de saúde do Distrito Federal: estudo transversal / Motoric cognitive risk syndrome in older adults at a health service in the Distrito Federal: a cross-sectional study

Resumo Objetivo Verificar a prevalência da síndrome de risco cognitivo motor (SRCM) em pessoas idosas do Distrito Federal (DF), Brasil, que frequentaram os serviços de saúde de uma unidade de referência em Geriatria e Gerontologia, comparar os grupos de idosos com e sem a síndrome e investigar os possíveis fatores associados ao desenvolvimento dessa síndrome. Método Trata-se de estudo observacional transversal analítico, desenvolvido com idosos (idade ≥60 anos) com marcha independente e sem alterações cognitivas graves, que possuíam registro de dados sociodemográficos, avaliação cognitiva, capacidade funcional e velocidade de marcha em prontuários datados de 2017 a 2019. A análise dos dados foi expressa em média e desvio-padrão, frequência e percentual, e em odds ratios (OR) com intervalos de confiança de 95%. As comparações entre os grupos com e sem a SRCM foram feitas por meio dos testes: qui-quadrado, U de Mann-Whitney e t de Student. Resultados Não houve diferenças significativas na comparação das variáveis entre os grupos. A prevalência da SRCM na população estudada foi de 24%. Nenhum dos fatores analisados demonstrou associação com a presença da síndrome. Conclusão A prevalência da SRCM na amostra foi de 24% e mostrou-se mais alta na população do DF quando comparada as populações estudadas em outros países. Não houve diferenças entre os grupos de idosos com e sem a síndrome, e os fatores associados não foram encontrados. O rastreio da síndrome é de extrema relevância, pois a partir desses achados pode-se desenvolver mecanismos para a prevenção de demência em idosos.

Abstract Objective To verify the prevalence of the motoric cognitive risk syndrome (MCR) in older adults from the Distrito Federal (DF), Brazil, who attended the health services of a reference unit in Geriatrics and Gerontology, compare groups of older adults with and without the syndrome and investigate the possible associated factors for the development of this syndrome. Method This is an observational cross-sectional analytical study, developed with older adults (age ≥ 60 years) with independent gait and without severe cognitive dysfunctions, who had a record of sociodemographic data, cognitive assessment, functional capacity and gait speed in medical records dated 2017 to 2019. Data analysis was expressed as mean and standard deviation, frequency and percentage, and odds ratios (OR) with 95% confidence intervals. Comparisons between groups with and without MCR were made using the chi-square, U Mann Whitney and t-student tests. Results There were no significant differences in the comparison of variables between groups. The prevalence of MCR in the studied population was 24%. None of the factors analyzed showed an association with the presence of the syndrome. Conclusion The prevalence of MCR in the sample was 24% and was shown to be higher in the population of the DF when compared to the populations studied in other countries. There were no differences between the groups of older adults with and without the syndrome, and the associated factors were not found. Screening for the syndrome is hugely relevant, as, from these findings, mechanisms can be developed to prevent dementia in old people.

Sintomas depressivos e funcionalidade em idosos da atenção primária de Porto Alegre (RS) / Depressive symptoms and functionality in older adults of the Porto Alegre's Primary Care

OBJETIVO: Determinar a prevalência de sintomas depressivos (SD) e a sua relação com aspectos funcionais, sociodemográficos e antropométricos em idosos da Estratégia Saúde da Família de Porto Alegre (RS). MÉTODOS: Trata-se de um estudo transversal prospectivo e analítico com amostra aleatória de 509 idosos de 30 unidades básicas de saúde. Analisaram-se idade, faixa etária, sexo, estado civil, escolaridade, peso, altura, índice de massa corporal, funcionalidade, atividades básicas e instrumentais de vida diária e presença de SD. Para análise estatística, utilizou-se o teste χ2 (bivariada) e de regressão logística (multivariada). RESULTADOS: A prevalência de SD na amostra foi de 35,4%. O modelo final apresentou associação estatisticamente significativa de SD com sexo feminino (odds ratio ­ OR = 2,87; intervalo de confiança de 95% ­ IC95% 1,92­9,23), analfabetismo [(OR = 2,13; IC95% 1,89­5,12), baixa escolaridade (OR = 1,23; IC95% 1,05­2,74), dependência em atividades instrumentais de vida diária (OR = 4,03; IC95% 1,68­9,64), baixos escores no teste senta/levanta (OR = 0,89; IC95% 0,82­0,96) e menor força de preensão manual (OR = 0,95; IC95% 0,93­0,98). CONCLUSÃO: A prevalência dos SD observada foi alta, e, ante as associações apresentadas, sugere-se que mulheres analfabetas ou com baixa escolaridade, com dificuldade em atividades instrumentais de vida diária, mais fracas e lentas devem ser investigadas quanto à presença de SD, pelo risco de desenvolvê-los.

OBJECTIVE: The aim of this study was to determine the prevalence of depressive symptoms (DS) and their relationship with functional, sociodemographic and anthropometric aspects in the older adults from the Family Health Strategy of Porto Alegre/ RS. METHOD: This is a cross-sectional, prospective and analytical study, with a random sample of 509 older adults from 30 public health units. The following variables were analyzed: age, age group, sex, marital status, schooling, weight, height and body mass index, functionality, activities of daily living, both basic and instrumental, and the presence of DS. For the statistical analyses, the bivariate qui-square test and the multivariate logistic regression were used. RESULTS: The prevalence of DS in this sample was 35,5%. The final model presented a significant statistical association of DS with female gender (OR = 2.87; IC95% 19.2-9.23), illiteracy (OR = 2.13; IC95% 1.89­5.12), low schooling (OR = 1.23; IC95% 1.05­2.74), dependence on IADL (OR = 4.03; IC95% 1.68­9.64), low scores in the sit-to-stand test (OR = 0.89; IC95% 0.82­0.96) and lower HGS (OR = 0.95; IC95% 0.93­0.98). CONCLUSION: The prevalence of DS observed was high (35.4%) and, considering the associations presented, it is suggested that illiterate or poorly educated, weaker and slower women with difficulty in IADL should be investigated for the presence of depressive symptoms, for being at the risk of developing them.

Neighborhood environmental factors associated with leisure walking in adolescents

ABSTRACT OBJECTIVE To verify the associations of leisure walking with perceived and objective measures of neighborhood environmental factors stratified by gender and socioeconomic status (SES) in Brazilian adolescents. METHODS Cross-sectional study with a random sample of 1,130 high school students (47.3% girls; aged 14 to 20 years old) from Porto Alegre, Brazil. Leisure walking and SES were self-reported by the adolescents. Perceived environmental factors were assessed through Neighborhood Environment Walkability Scale for Youth (NEWS-Y). Objective measures were evaluated using Geographic Information Systems, with road network calculated around the adolescent's residential address, using 0.5km and 1.0km buffers. Data collection was carried out in 2017 and generalized linear regression models were used. RESULTS Leisure walking was positively associated with access to services (0.5 km buffers [Odds ratio (OR) = 2.22] 1.0 km buffers [OR = 2.17]) and lower distance to parks and squares (0.5 km [OR=2.80] 1.0 km [OR = 2.73]) in girls from low SES. Residential density (0.5 km [OR = 1.57] 1.0 km [OR = 1.54]) and walkability index (0.5 km [OR = 1.17] 1.0 km [OR = 1.20]) were associated with leisure walking in girls from middle SES. Boys from low SES showed an inverse association between crime safety and leisure walking (0.5 km [OR = 0.59] 1.0 km [OR = 0.63]). Neighborhood recreation facilities was positively associated with leisure walking in middle SES (0.5 km [OR = 1.55] 1.0 km [OR = 1.60]). Land use mix (0.5 km [OR = 1.81] 1.0 km [OR = 1.81]), neighborhood recreation facilities (0.5 km [OR = 2.32] 1.0 km [OR = 2.28]) and places for walking (0.5 km [OR=2.07] 1.0 km [OR=2.22]) were positively associated with leisure walking in high SES. CONCLUSION Environmental factors (objectively and subjectively measured) and leisure walking show association in boys and girls of different SES.

Prevalence and factors associated with active transportation to school for adolescents / Prevalência e fatores associados ao transporte ativo para a escola em adolescentes

ABSTRACT OBJECTIVE: To verify the prevalence and factors associated with active transportation to school (ATS) among Brazilian adolescents attending public schools. METHODS: Crossectional study with a representative sample of 1,984 adolescents (55.9% girls). Sociodemographic variables included were: gender, age, parental schooling, and socioeconomic status. Psychosocial factors included were: social support from parents and friends for physical activity. Walking, cycling, or skateboarding to school were considered models of active transportation. Binary logistic regression models verified sociodemographic and psychosocial factors association with ATS, adopting p < 0.05. RESULTS: The prevalence of active transportation to school was 37.7% (16.2% boys and 21.5% girls). For boys, ATS was associated with: social support from parents in practicing physical activity together as a family (OR = 1.57; 95%CI 1.09-2.25), giving them rides (OR = 1.56; 95%CI 1.04-2.32), and remarking their good performance on it (OR = 1.73; CI95 1.08-2.76); as well as the social support from friends in practicing physical activity together (OR = 2.23; 95%CI 1.35-3.69). For girls, the likelihood of using ATS increased with age (OR = 1.43; 95%CI 1.06-1.92) and having friends who practice physical activity together with them (OR = 1.48, 95%CI 1.04-2.10). CONCLUSION: Age and social support for physical activity were associated with ATS. Parents who practice together, give rides, and remark on physical activities increase the likelihood of adolescent boys using ATS. Social support from friends to physical activity increased the likelihood of both genders using ATS.

RESUMO OBJETIVO: Verificar a prevalência e os fatores associados ao transporte ativo para a escola em adolescentes brasileiros de escolas públicas. MÉTODOS: Estudo transversal, com amostra representativa de 1.984 adolescentes (55,9% meninas). Os fatores sociodemográficos incluídos foram sexo, idade, escolaridade dos pais e nível socioeconômico. Os fatores psicossociais incluídos foram apoio social dos pais e dos amigos para a atividade física. Foi considerado transporte ativo o ato de caminhar, pedalar ou usar skate no deslocamento para a escola. Modelos de regressão logística binária verificaram a associação dos fatores sociodemográficos e psicossociais ao transporte ativo para a escola adotando p < 0,05. RESULTADOS: A prevalência de transporte ativo para a escola foi de 37,7% (16,2% meninos e 21,5% meninas). Para meninos, o apoio social dos pais ao praticar atividade física junto (RC = 1,57; IC95% 1,09-2,25), transportar para a atividade física (RC = 1,56; IC95% 1,04-2,32) e comentar que o adolescente faz a atividade física bem (RC = 1,73; IC95% 1,08-2,76), assim como o apoio dos amigos ao praticar junto (RC = 2,23; IC95% 1,35-3,69), foram associados ao transporte ativo. Para meninas, a idade (RC = 1,43; IC95% 1,06-1,92) e ter amigos que praticam atividade física junto (RC = 1,48; IC95% 1,04-2,10) aumentaram as chances de transporte ativo para a escola. CONCLUSÃO: A idade e o apoio social para a prática de atividade física foram associados ao transporte ativo para a escola. Pais que praticam junto, transportam e comentam sobre a atividade aumentaram as chances para adolescentes meninos. O apoio social dos amigos para a atividade física aumentou as chances para ambos os sexos.

Determinants of Work in the Six-Minute Walk Test in School-Age Children / Determinantes do trabalho no Teste de Caminhada de Seis Minutos em escolares

Abstract Introduction: The Six-Minute Walk Test (6MWT) is widely used to assess functional capacity in children. The measure of work during 6MWT can add important information to the 6MWT assessment in this population as it relates to walking efficiency. Objective: To verify the determinants of work during the Six-Minute Walk Test (6MWTwork) in school-aged children. Method: This is a cross-sectional and exploratory study that included healthy children recruited from the public and private schools of the cities of Belo Horizonte and Uberlândia, Brazil. The inclusion criteria were: children aged 7 to 12 years without diagnosis of chronic cardiorespiratory disease, cognitive, behavioral disorder or physical function impairment (information obtained through self-report of those responsible for children). Exclusion criteria were children who refused to perform the 6MWT; who did not understand the 6MWT or who did not answer the test commands. Three hundred and nineteen school-aged children were included in the study. Correlation analyses and multiple linear regression analysis were used to identify the variables associated with the 6MWTwork. Results: Age, height, nutritional status, physical activity and heart rate showed significant correlation with 6MWTwork (p <0.001) and explained 87% of its variation (p = 0.0001). Conclusion: Age, height, nutritional status and heart rate variation are determinants of 6MWTwork that is able to evaluate functional capacity of school-aged children.

Resumo Introdução: O teste de caminhada de seis minutos (TC6min) é amplamente utilizado para avaliar a capacidade funcional em crianças. A medida do trabalho durante o TC6 poderia adicionar informações importantes à avaliação do TC6 nessa população, no que se refere à eficiência da marcha. Objetivo: Verificar os determinantes do trabalho durante o Teste de Caminhada (TC6min) em crianças em idade escolar. Método: Trata-se de um estudo transversal e exploratório que incluiu crianças saudáveis recrutadas nas escolas públicas e privadas das cidades de Belo Horizonte e Uberlândia, Brasil. Os critérios de inclusão foram: crianças de 7 a 12 anos sem diagnóstico de doença cardiorrespiratória crônica, distúrbio cognitivo, comportamental ou comprometimento da função física (informações obtidas por auto-relato dos responsáveis pelas crianças). Os critérios de exclusão foram: crianças que se recusaram a realizar o TC6; que não entenderam o TC6 ou que não responderam aos comandos de teste. Trezentos e dezenove crianças em idade escolar foram incluídas no estudo. Análises de correlação e análise de regressão linear múltipla foram utilizadas para identificar as variáveis associadas ao trabalho com TC6. Resultados: Idade, altura, estado nutricional, atividade física e frequência cardíaca apresentaram correlação significativa com o trabalho durante o TC6min (p <0,001) e explicaram 87% de sua variação (p = 0,0001). Conclusão: Idade, altura, estado nutricional e variação da frequência cardíaca são determinantes do trabalho no TC6, e portanto, devem ser considerados na avaliação da capacidade funcional de crianças em idade escolar.

Utilitarian walking and walking as exercise among community-dwelling older adults: what factors influence it? / Caminhada utilitária e caminhada como exercício para os idosos: quais fatores podem influenciar?

Abstract Objective : to investigate the association between utilitarian walking and walking as exercise, and socio-demographic, clinical and functional covariates related to these walking types. Methods : a cross-sectional exploratory study was conducted with 148 older adults (aged 60 and over). Walking frequency and duration was assessed using the IPEQ-W (Incidental and Planned Exercise Questionnaire - Version W). Socio-demographic, clinical conditions, level of disability and mobility were also assessed. Types of walking were compared among the variables using the Mann-Whitney test and non-parametric Spearman rho correlations were used to investigate the association between the types of walking and the variables. Results : the participants performed a mean of 1.1 (±2.1) h/week of walking as exercise and 2.2 (±2.3) h/week of utilitarian walking. Older adults who had diabetes (p=0.015) did fewer h/week of walking as exercise. Participants who were older (p=0.014), reported poor self-rated health (p<0.001), poor disability levels (p<0.001), hypertension (p=0.048), strokes (p<0.001), heart disease (p=0.026), urinary incontinence (p<0.001), dizziness (p=0.008), or sleep disorders (p=0.042) spent fewer hours performing utilitarian walking. Correlations between the covariates and types of walking varied from very weak to weak. Conclusion : chronic diseases and unfavorable health conditions decreased walking time. Utilitarian walking was the most frequent type of walking performed by the older adults. Health care professionals and public policy managers should use utilitarian walking as a way of increasing levels of physical activity and to promote healthy aging.

Resumo Objetivo : Investigar a associação entre a caminhada utilitária, a caminhada como exercício e variáveis sociodemográficas, clínicas e funcionais associadas a esses tipos de caminhada. Métodos : Foi conduzido um estudo transversal exploratório, com 148 idosos (com 60 anos de idade ou mais). A frequência e duração da caminhada foi avaliada por meio do IPEQ-W (Incidental and Planned Exercise Questionnaire - Version W). Dados sociodemográficos, condições clínicas, nível de funcionalidade e mobilidade também foram avaliados. O teste de Mann-Whitney foi utilizado para comparar os tipos de caminhada com as variáveis e o teste de correlação de Spearman rho foi utilizado para analisar a associação entre os tipos de caminhada e as variáveis. Resultados : Participantes realizaram em média 1,1 (±2,1) h/semana de caminhada como exercício e 2,2 (±2,3) h/semana de caminhada utilitária. Participantes mais velhos (p=0,014), com pior percepção de saúde (p<0,001), com pior funcionalidade (p<0,001), que relataram hipertensão (p=0,048), AVE (p<0,001), doença do coração (p=0,026), incontinência urinária (p<0,001), tontura (p=0,008), problemas para dormir (p=0,042) e polifarmácia (p=0,019) fizeram menos horas de caminhada utilitária. A correlação entre as covariáveis e os tipos de caminhadas variou de muito fraca a fraca. Conclusão : Doenças crônicas e condições desfavoráveis de saúde diminuem o tempo de caminhada. A caminhada utilitária é a mais comumente realizada pelos idosos. Profissionais de saúde e gestores de políticas públicas devem usar a caminhada utilitária como uma forma de aumentar o nível de atividade física e promover o envelhecimento saudável.

Effect of implementation intention on walking in people with diabetes: an experimental approach

ABSTRACT OBJECTIVE To evaluate the effect of implementation intentions as an intervention strategy to promote walking in adults with type 2 diabetes mellitus (T2DM). METHODS We conducted a controlled and randomized trial, with 12 months of follow-up, involving 65 people with T2DM recruited from primary health care units and allocated them in the control group (CG, n = 32) and intervention group (IG, n = 33). The IG received the implementation intention strategy to promote walking and the CG remained in follow-up for conventional treatment in primary health care. The researchers were blinded by anthropometric measurements and the filling of the instruments. RESULTS After twelve months of follow up, the IG presented a statistically significant increase in the leisure time physical activity when compared with the CG (p = 0.0413) and showed a significant decrease in waist circumference (p = 0.0061). No significant difference was observed regarding body mass index and glycated hemoglobin among groups. CONCLUSIONS Implementation intention was effective in promoting walking and improving clinical indicators in adults with T2DM.

Moderate-Intensity Walking Training Improves Depressive Symptoms and Pain in Older Adults with Good Quality of Life: A Controlled Randomized Trial

Abstract Background: Walking training can be an adequate choice to improve physical and psychological conditions in the elderly. Studies have reported positive changes in the quality of life, depressive symptoms and pain. However, baseline characteristics of volunteers have been controlled, and some of previous studies have not investigated these parameters concomitantly. Objectives: To assess the effects of moderate-intensity walking on quality of life, depressive symptoms and physical pain in physically active elderly individuals. Methods: Sixty-nine subjects were recruited and allocated into two groups: training group (n = 40) and control group (n = 29). All were evaluated for quality of life, depressive symptoms and pain. Training group underwent 40 minutes of walking (50-70% of maximum heart rate), 3 days a week for 12 weeks. For statistical analysis, we used the Kolmogorov-Smirnov test, Student's t-test and Split-Plot ANOVA with Bonferroni post hoc, Pearson correlation. Significance level was set at 5%. Results: After 12 weeks of training, depressive symptoms and physical pain significantly reduced in the training group (2.7 ± 2.4 to 1.9 ± 1.8 and 4.3 ± 3.1 to 2.8 ± 2.9, respectively) compared with baseline values, and remained unchanged in the control group. There was a positive, moderate correlation between depressive symptoms and pain (r = 0.30). Conclusion: physically active elderly individuals with good quality of life show improved depressive symptoms after a short-term moderate-intensity walking training program.

Exercício com intensidade autosselecionada para idosos: implicações do afeto em aulas comunitárias / Self-selected intensity exercise for the elderly: implications of affect in community classes

A prescrição da intensidade do exercício de forma autosselecionada em função de maior afeto positivo é uma estratégia utilizada para promover aderência da população na prática de exercícios. Entre-tanto, ainda não foram investigadas as implicações que essa estratégia pode gerar na valência afetiva de idosos em ambientes não laboratoriais e em aulas em grupos. O objetivo desse estudo foi analisar se o exercício com intensidade autosselecionada realizado em grupos de idosos pode influenciar na valência afetiva. A amostra foi composta por 176 idosos, sendo 42 homens, com média de idade 70,70 ± 10,10 anos e 134 mulheres, com média de idade 71,00 ± 6,60 anos. Os idosos vinculados a um centro comunitário reportaram a valência afetiva e percepção subjetiva de esforço após uma caminhada de 30 minutos com intensidade autosselecionada. Os participantes foram alocados em três grupos segundo os tercis de percepção subjetiva de esforço: grupo com baixa (GBPE), média (GMPE) e alta (GAPE) percepção de esforço. Foi identificado que todos grupos se diferenciam entre si na valência afetiva [c² (2) = 50,860; p < 0,05]. A magnitude das diferenças pelo tamanho de efeito foi moderada na análise global (*ES = 0,331) e entre GBPE e GAPE (ES = 0,329). Conclui-se existe uma implicação negativa na valência afetiva em exercício com autosseleção da intensidade rea-lizados por idosos em grupos comunitários, possivelmente causado por fatores psicossociais capazes de influenciar na variabilidade de respostas perceptivas

The self-selected exercise intensity prescription due to greater positive affect is a strategy used to promote adherence of the population to exercise. However, the implications that this strategy may have on the affective valence of the elderly in non-laboratory environments and in group classes have not still investigated. The purpose of this study was to analyze whether self-selected intensity exercise performed in elderly groups can influence affective valence. The sample consisted of 176 elderly, 42 men, with a mean age of 70.70 ± 10.10 years and 134 women, with a mean age of 71.00 ± 6.60 years. The elderly linked to a community center reported affective valence and rating perceived exertion after a 30-minute walk with self-selected intensity. Participants were allocated to three groups according to the terciles of rating perceived exertion: group with low (GBPE), medium (GMPE) and high (GAPE) perceived exertion. It was identified that all groups differ in affective valence [c² (2) = 50,860; p <0.05]. The magnitude of the differences by effect size was moderate in the overall analysis (*ES = 0.331) and between GBPE and GAPE (ES = 0.329). In conclusion, there is a negative implication in affective valence in self-selected exercise intensity performed by the elderly in community groups, possibly caused by psychosocial factors capable of influencing the variability of perceptual responses

Medo de cair e risco de quedas em idosos assistidos por uma clínica escola de reabilitação / Fear and risk of falls in elderly assisted at a university rehabilitation service

Introdução: A queda é um fenômeno indesejável para pessoa idosa (PI), pois, pode culminar em prejuízo funcional e aumento da mortalidade. O rastreamento do risco de cair da PI facilita a implementação de estratégias específicas de prevenção. Objetivo: Avaliar o risco, o medo de cair e as variáveis associadas ao medo de cair de PI atendidas por uma clínica escola de reabilitação (CER) na cidade de São Paulo, Brasil. Casuística e Método: Estudo transversal que compreendeu 40 PI (72,5% do gênero feminino; idade média 68±7,63 anos) atendidas na CER. A coleta de dados consistiu (i) na aquisição de dados demográficos e na avaliação (ii) do medo de cair (Escala de Avaliação da Autoeficácia de Quedas- FES-I); (iii) do risco de quedas (Timed Up and Go ­ TUG e Berg Balance Scale - BERG); (iv) da velocidade de marcha (Teste de Velocidade de Marcha de 6 Metros - 6mVelMar). O coeficiente de correlação de Spearman foi calculado para verificar associação entre a FES-I e as demais variáveis coletadas. Resultados: Trinta e cinco porcento dos participantes eram caidores e reportaram, em média, 2 quedas nos últimos 6 meses. A idade, TUG (mediana: 11 segundos; IQ: 9,00-13,75), BERG (mediana: 54 pontos; IQ: 48-55) e 6mVelMar (média: 1,20±0,39 m/s) apresentaram associação com a pontuação de FES-I (mediana: 23 pontos; IQ: 19,25­33,50; p < 0,001). A BERG foi a variável que apresentou associação moderada e negativa com a FES-I (coeficiente de correlação: -0,601; p < 0,001). As variáveis como sexo, ocorrência de quedas, número de quedas e polifarmácia não apresentaram associação com a pontuação da FES-I. Conclusão: A despeito do baixo risco de quedas, as PI apresentaram medo de cair. O medo de cair esteve associado à idade, ao equilíbrio, ao tempo de TUG e à velocidade de marcha.

Introduction: Fall is an undesirable phenomenon to elderly people (EP), because, may lead to functional impairment and increased mortality. The screening of risk of falls in EP facilitates the implementation of specific strategies of prevention.Objective: To verify the risk, the fear of fall and variables associated to the fear of fall in EP assisted in a university rehabilitation service located in São Paulo State, Brazil. Patients and Methods: We carried out a cross-sectional study which enrolled 40 EP (72.5% females; mean age of 68±7.63 years old). The data collection comprised (i) demographic data and assessment of (ii) fear of fall (Falls Efficacy Scale-International ­ FES-I), (iii) risk of fall (Timed Up and Go ­ TUG and Berg Balance Scale - BERG), (iv) gait speed (6-meter gait speed). The Spearman correlation coefficient was calculated to verify association among FES-I and other variables collected. Results: Thirty-five percent of participants have reported frequent falls at a rate of at least 2 falls in the last six months. Variables such as age, TUG (median: 11 seconds; IQR: 9.00-13.75), BERG (median: 54 points; IQR: 48-55), and 6-meter gait speed (mean: 1.20±0.39 m/s) showed an association with FES-I (median:23 points; IQR: 19.25­33.50) (p < 0.001). BERG scale presented a moderate and negative association with FES-I (correlation coefficient: -0.601; p < 0.001). Variables as gender, polypharmacy, occurrence and number of falls were not associated with FES-I. Conclusion: Despite the low risk of fall, the EP reported fear of fall. The fear of fall was associated to age, balance, TUG and gait speed.

Fragilidad en ancianos oncológicos en tratamiento con quimioterapia / Frailty in elderly oncology patients in chemotherapy treatment

RESUMEN Los ancianos están más expuestos al desarrollo del cáncer, pues el envejecimiento deja las células más susceptibles a la transformación maligna. Identificar la fragilidad puede contribuir a mejorar resultados en el tratamiento antineoplásico. El objetivo de este estudio fue identificar la prevalencia y grado de fragilidad en ancianos oncológicos en tratamiento con quimioterapia e investigar factores asociados al síndrome. Se incluyeron pacientes ≥60 años en nivel ambulatorio. La fragilidad se evaluó a partir del fenotipo desarrollado en la Universidad Johns Hopkins. El nivel de significancia adoptado para todas las pruebas fue menor que p<0,05. De la muestra de 60 individuos, el 55,0% era hombres, con promedio de edad 69,8±7,6. Entre los pacientes evaluados, el 66,7% presentaron fragilidad y el 33,3% pre-fragilidad. Las mujeres fueron más frágiles (81,5% vs 54,5%; p= 0,028) y la fragilidad tendió a ser mayor entre los caquécticos (81,8% vs 57,9%; p= 0,051). Concluimos que hubo un porcentaje elevado de pacientes frágiles y pre-frágiles. El sexo femenino y el sedentarismo se presentaron como factores asociados.

ABSTRACT The elderly are more at risk for developing cancer, as aging leaves cells more susceptible to malignant transformations. Identifying frailty can contribute to improved outcomes in antineoplastic treatment. The purpose of this study was to identify the prevalence and degree of frailty in elderly cancer patients undergoing chemotherapy treatment and investigate factors associated with this syndrome. Ambulatory patients> 60 years were included. Frailty was assessed from the phenotype developed by Johns Hopkins University. The significance level adopted for all tests was p<0.05. From the sample of 60 individuals, 55.0% were men, with mean age 69.8 ± 7.6. Among the patients evaluated, 66.7% presented frailty, and 33.3% pre-frailty. Women were more frail (81.5% vs 54.5%; p= 0.028) and frailty tended to be higher among cachectic patients (81.8% vs 57.9%; p= 0.051). We concluded that there was an elevated percentage of frail and pre-frail patients. Female sex and sedentarism were associated factors.

Fiabilidad de dos pruebas de velocidad de marcha de diferentes fases cronometradas e iguales fases no cronometradas en personas mayores que viven en la comunidad / Reliability of two gait speed tests of different timed phases and equal non-timed phases in community-dwelling older persons

ANTECEDENTES La velocidad de la marcha es una medida rápida, económica y precisa para evaluar la capacidad funcional de las personas mayores, tanto saludables como con diferentes comorbilidades. Estudios previos han evaluado la velocidad de la marcha medida a lo largo de cursos de diferentes distancias, pero las fases no cronometradas no se miden de manera uniforme y se desconoce si esto afecta los resultados de la prueba. OBJETIVO El objetivo de este estudio fue evaluar la confiabilidad de la prueba de velocidad de marcha de diferentes fases cronometradas e iguales fases no cronometradas. MÉTODOS Estudio de confiabilidad descriptivo, con diseño observacional analítico y de corte transversal. Se incluyeron 136 personas mayores. Se realizaron pruebas de 4 y 10 metros, con 2 metros para la fase de aceleración/desaceleración de ambas. El promedio de dos intentos se obtuvo como la medida final de cada prueba. Los resultados se obtuvieron mediante el coeficiente de correlación intraclase (CCI) con un modelo de efectos fijos y el método Bland y Altman (con un intervalo de confianza del 95%). Se complementaron con los valores de error estándar de la media y del cambio mínimo detectable (CMD95). RESULTADOS Los resultados indican un excelente nivel de acuerdo entre los intentos de las pruebas de 4 y 10 metros (CCI = 0,959 y 0,976, respectivamente), así como entre el promedio de las dos pruebas (CCI = 0,867). Destaca un nivel de acuerdo ligeramente mejor entre los dos intentos de la prueba de 10 metros. Por lo tanto, el número de intentos no es capaz de afectar los resultados de la velocidad de la marcha; sin embargo, se requieren análisis adicionales para concluir lo mismo con respecto a la distancia de la prueba. La diferencia del análisis Bland Altman para el promedio de las pruebas de 4 y 10 metros fue 1,5945 m/s (intervalo de confianza 95%: 0,9759 a 2,2130 m/s), siendo demasiado grande y más alto que el valor CMD95. CONCLUSIONES El CCI fue excelente en todos los casos, pero se requiere un análisis adicional para concluir lo mismo con respecto a la distancia de la prueba. Existe un acuerdo insuficiente entre las dos pruebas para permitir que se utilicen indistintamente en poblaciones con las características de este estudio.

BACKGROUND Gait speed is a fast, low cost and accurate measurement for evaluating older persons' functional ability, both health and with comorbidities. Previous studies have evaluated gait speed measured over courses of varying distances, but the non-timed phases are not measured uniformly. It is unknown if this affects the results of the test. OBJECTIVE This study aims to evaluate the reliability of the running speed test of two different timed phases compared to the same nontimed phases. METHODS We conducted a descriptive reliability study, with an observational and cross-sectional analytical design. One hundred thirty-six older persons were included. Two gait speed tests were taken, one of 4 and 10 meters, and 2 meters for the acceleration/deceleration phase for both tests. The average of two attempts was obtained as a final measure of each test. The intraclass correlation coefficient was used to express the results (ICC) with a fixed effects model and the Bland and Altman method (confidence interval of 95%), complemented with the standard error of the mean and minimal detectable change with 95% confidence values (MDC95). RESULTS The results indicate an excellent level of agreement between the attempts of the tests of 4- and 10-m (ICC = 0.959 and 0.976, respectively), as well as between the average of the two tests (ICC = 0.867). The agreement was slightly better between the two attempts in the 10-meter test. The number of attempts does not affect the results of gait speed. Further analysis is required to conclude the same regarding the distance of the test (4 and 10 meters). The difference in the results of the Bland Altman analysis for the average of the 4 and 10-meter tests was 1.5945 m/s (95% confidence interval: 0.9759 to 2.2130 m/s), which is too wide and higher than the MDC95 value. CONCLUSIONS The ICC value was excellent in all cases, and the number of attempts does not affect the results of gait speed. However, further analysis is required to conclude the same regarding the distance of the test. There is an insufficient agreement between the two tests to allow them to be used interchangeably in populations with the characteristics of this study.

Association between the results of the timed up-and-go test adjusted for disease severity and sarcopenia in patients with chronic obstructive pulmonary disease: a pilot study

OBJECTIVES: Loss of muscle mass and/or physical performance, a condition commonly known as sarcopenia, is prevalent in chronic obstructive pulmonary disease (COPD) and is associated with adverse outcomes. The aim of this study was to investigate the association between functional performance and sarcopenia in COPD patients classified by disease severity according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) criteria. METHODS: The study was a cross-sectional observational and the sample size consisted of 35 COPD patients (69.24±1.54 years, 20 men). Physical performance was assessed with the timed up-and-go (TUG) test. Sarcopenia was assessed according to the European Working Group on Sarcopenia in Older People criteria. RESULTS: The frequency of sarcopenia was 20% and was more prevalent among individuals classified with greater disease severity, GOLD III, n=4 patients (23%) and GOLD IV, n=3 patients (27%), p=0.83. The mean time to complete the TUG test was 11.66±4.78 s. Binary logistic regression revealed an association between the TUG test and sarcopenia adjusted by disease severity (OR=1.55, 95% CI: 1.03-8.23, p=0.04). CONCLUSION: Our findings showed that worse performance in the TUG test leads to a substantial increase in the chance of COPD patients presenting sarcopenia.
