RESUMEN

The current study aimed to follow the effects of social/physical distancing strategies on health-related daily physical activity and quality of life among older adults during the COVID-19 pandemic. Seventy-two older adults who were enrolled in a University-Community program in March 2020 (age = 66.8 ± 4.82 years, ♀59) answered five phone-based surveys up to 120 days after the COVID-19 outbreak (from April to August 2020). The Short Form 6D and international physical activity (short version) questionnaires were applied. A significant reduction was observed in daily physical activity levels, metabolic equivalent of task, and health-related quality of life scores as well as an increase in sitting time during the week and on weekend days (all p < .01). The authors noted differences in lifestyle conditions at the beginning of the social/physical distancing in the community assessed (p < .01). Health vulnerabilities among older adults have been emphasized during the COVID-19 outbreak, impacting daily physical activity and health-related quality of life.

RESUMEN

The objective was to investigate the association between rate of torque development (RTD) and torque steadiness (TS) of the lower limb and the occurrence of prospective falls in community-dwelling older adults without falls in the previous year. One hundred older adults performed the tests to obtain the RTD and TS of the hip, knee, and ankle. New episodes of falls were monitored through telephone contact for a prospective period of 12 months. The association of RTD and TS with the occurrence of prospective falls was verified by multiple logistic regression adjusted for confounding variables. There was no association between RTD of hip, knee, and ankle and prospective falls. Only the TS at 50% of the peak torque of the hip flexors was associated with the occurrence of future falls (p = .023). Identifying modifiable risk factors for the first fall in older adults is essential for the development of adequate prevention programs.

RESUMEN

The objective of this study was to compare the functional performance of community-dwelling older adults of both sexes and investigate the possible mediation aspects that may influence the sex differences regarding socioeconomic and anthropometric characteristics, health status, and quadriceps muscle strength. 233 Brazilian older adults were assessed, and men's and women's sociodemographic data, physical activity level, quadriceps muscle strength, functional performance (gait speed and the SPPB), and history of falls were compared. Sex differences in functional performance were observed even after statistically adjusting the model (age, body mass, income, physical activity level, and occurrence of falls). When quadriceps muscle strength was included in the adjusted model, the sex difference remained only for gait speed. When stature was included in the adjusted model, the sex difference in gait speed disappeared. Our results suggest that the sex difference in functional performance assessed by the SPPB can be explained due to the fact that men are stronger than women. In addition, the sex difference regarding gait speed was explained by the sex difference in stature. Public actions that encourage older women to practice physical activities that promote increased muscle strength can positively interfere with their best functional performance for as long as possible.

RESUMEN

BACKGROUND: Despite the clinical importance, it has remained unclear which changes in the trunk muscle function parameters are more associated with the presence of vertebral fracture (VF). AIMS: The aim of this study was to verify the association between the trunk muscle function performance and the presence of VF in older women with low bone mass. The secondary aim was to evaluate the correlation between trunk muscle function and both fall history and muscle mass. METHODS: This cross-sectional study was composed by 94 women over 60 years within value of T-Score lumbar spine BMD <- 1.0 DP. Multidimensional evaluations were performed: appendicular skeletal muscle mass index (ASMI) was determined by the total body DEXA; the radiographic evaluations measured the degree of thoracic kyphosis and classification of VF. The trunk muscle function parameters, such as peak torque (PT), rate of torque development (RTD) and torque steadiness (TS) were evaluated by isokinetic dynamometer. The trunk muscle endurance was evaluated by the timed loaded standing test. The adjusted multivariate logistic regression model and multivariate linear regression were performed to verify the association between the variables studied. RESULTS: The results showed that the trunk muscle function parameter with greater association with the presence of VF is TS extensors (OR = 1.70; p < 0.001). The other two significant muscle parameters were: RTD30 flexors (OR = 0.31; p = 0.033) and PT extensors (OR = 0.13; p = 0.009). No statistical association was found between the presence of VF and the ASMI and trunk muscle endurance. No correlation between trunk muscle function and fall history was observed. There was a weak correlation between ASMI and extensor PT (R2 = 0.21; p = 0.027) and extensor RTD30 (R2 = 0.21; p = 0.026). CONCLUSIONS: This study demonstrated that deficit in trunk muscle function has shown a strong association with the presence of VF, highlighting issues heretofore unexplored regarding the association between VF with muscle power and motor control.

RESUMEN

BACKGROUND: The previous studies have investigated causes of and risk factors for falls and impairment of functional capability in older adults. However, the biomechanical factors involved in functional performance and postural control, and the contribution of hip muscles, are still unknown. AIMS: The aim of the present study was to verify the association between the muscle function of hip abductors and adductors and static and dynamic balance, in a narrow base of support, in community-dwelling older adults. METHODS: Eighty-one older adults, including both women and men, were evaluated. Tandem gait and single-leg stance were used to assess static and dynamic balance, and an isokinetic dynamometer was used to analyze muscle function (peak torque and rate of torque development according to body weight). Data were analyzed by a multivariate linear regression test without adjustment and with adjustment using two models: adjustment I (sex) and adjustment II (age). RESULTS: There was a statistically significant association between peak torque of abductor in single-leg stance and tandem gait speed. The PT of hip adductors contributed to static balance performance, in a narrow base of support from the unadjusted data and from the adjusted data by sex. CONCLUSION: The findings of the present study are relevant, because if deficits in balance and functionality in older adults can be linked to a decline in maximum muscle strength of hip abductors, this parameter can be treated to maintain independence in older adults for as long as possible.

RESUMEN

The Therasuit method is a valuable physiotherapeutic method to improve the gross motor function of children with neuromotor disorders. This series of case studies investigates the effect of the Therasuit method on the gross motor function of children with autism spectrum disorder (ASD). Therasuit method is a therapeutic intervention that involves the use of a therapeutic suit attached to a cage to stimulate gross motor skills, muscle strengthening, stretching, task training, and balance, which is a positive intervention for other neurodevelopmental disorders. The study was conducted with nine male children (42.1 + 4.1 months old) with ASD who received the Therasuit protocol for 4 weeks (20 sessions). The Gross Motor Function Measure (GMFM-88) was used to assess the children's gross motor function before and after the Therasuit method intervention. In dimension B, several skills showed improvement, including transfer to sitting, lean forward and return, trunk rotation without support, and transfer from sitting to all four stances. In dimension C, an increase was observed in skills such as being prone to all four stance transfers and reaching above the shoulders. In dimension D, maximum scores were achieved in skills such as pulling to stand on a large bench without assistance. The dimensions with the greatest impairment were D and E, corresponding to gross motor skills in orthostasis and dynamic skills in orthostasis, respectively. The findings suggest that the Therasuit method is a promising resource for treating motor impairments in children with ASD. However, further studies with a larger sample size, an adequate control condition, and random assignment of participants would be needed to provide stronger evidence of the method's effectiveness in this population.

RESUMEN

OBJECTIVES: To determine the accuracy of the 5-time stand-to-sit (5TSTS) test for the identification of older adults with reduced gait speed. DESIGN: Cross-sectional study. SETTING AND PARTICIPANTS: A total of 559 community-dwelling older adults were included in the study, divided into groups of women (n = 465) and men (n = 94). METHODS: 5TSTS and gait speed were assessed. Multiple linear regression analysis with adjustment was performed in order to determine the association between 5TSTS and gait speed, followed by the receiver operating characteristic (ROC) curve for the identification of the usefulness of 5TSTS to discriminate older adults with reduced gait speed. Based on the ROC curve, we identified the area under the curve, the sensitivity, specificity, and cutoff points of the 5TSST. Statistical analyses were made using the SPSS software (version 25.0), and a significance level of 5% (P ≤ .05) was adopted. RESULTS: The 5TSTS showed correlation with gait speed. Additionally, 5TSTS was able to discriminate reduced gait speed with moderate accuracy (P < .05; AUC between 0.7 and 0.8). For women, the cutoff scores for 5TSTS to identify gait speed <0.8 m/s was 14.15 seconds; for gait speed <1.0 m/s, it was 12.67 seconds. For men, the cutoff scores for 5TSTS to identify gait speed <0.8 m/s was 14.67 seconds, and for gait speed <1.0 m/s, it was 13.63 seconds. CONCLUSION AND IMPLICATIONS: The 5TSTS is clinically useful and can be an alternative assessment for discriminating community-dwelling older adults with reduced gait speed, when the gait evaluation is not feasible. The study also suggests different cutoff values for 5TSTS considering the gait speeds <0.8 and <1.0 m/s for older women and men, respectively.

RESUMEN

BACKGROUND: Understanding of the influence of trunk muscles on the older adult's limit of stability (LOS) is important for clinical practice. OBJECTIVE: To compare the anterior and posterior LOS and the flexor and extensor trunk muscle function; verify the association of trunk muscles and LOS, and the association of LOS and the previous falls of community-dwelling older adults. METHODS: Sample characterization data, trunk muscle function (peak torque - PT and torque steadiness - TS), LOS and previous falls (6 months) were collected from 79 older people. Comparisons were made between the variables of the anterior/posterior LOS (Reaction time, Movement velocity, Maximum excursion, Directional control), between trunk extensors/flexors muscle function and between TS at 10% and at 50%. Associations were made between the anterior/posterior LOS and the number of previous falls and between LOS and trunk muscle function. RESULTS: The posterior LOS was worse than the anterior LOS, except for the reaction time. The flexor muscles obtained a lower PT, but better performance in TS. The TS at 10% of the trunk extensor was associated with the posterior directional control (p = 0.032). There was no association between trunk muscle function and the anterior LOS, or between previous falls and LOS. CONCLUSIONS: The older adults presented worse performance in the posterior LOS and worse TS in the trunk extensor muscles, although the trunk extensor muscles presented a higher PT. Although no association between LOS and previous falls, the better the TS at 10% of the trunk extensors, better posterior directional control.

RESUMEN

The study aimed to identify the prevalence of frailty syndrome and its associated factors in older adults residents in an urban area in the interior of Amazonas, Brazil. This is a population-based cross-sectional study with a sample of 265 older adults (60 years or older), representative of the urban area of Coari-AM. Using the adapted Fried phenotype, those with 3 criteria or more were considered frail. Socio-demographic, health, and functionality information was collected. Multivariate analysis was used through Poisson regression with robust variance, using a hierarchical method for the dichotomous outcome of frailty. The prevalence of frailty was 9.4 % and in the final multivariate analysis model the factors associated with frailty were: advanced age (PR: 4.1; 95 % CI: 1.8-9.3), income less than one minimum wage (PR: 3.4; 1.7-6.9), masonry housing (PR: 3.3; 1.3-8.2), never having lived in a riverside community (PR: 2.7; 1.4-5.4), use of 3 medications or more (PR: 3.1; 1,4-6.9), history of falling (PR: 2.3; 1.1-4.9), and fear of falling (PR: 4.1; 1.3-13.0). The study concluded that the prevalence of frailty in Coari-AM was lower than other Brazilian cities with a similar HDI. In addition to factors associated with frailty already well described in the literature, the influence of the Amazonian culture and environment during the course of life was shown to have a possible protective effect on health outcomes in later life.

RESUMEN

OBJECTIVE: to investigate the accuracy of the step test (ST) to evaluate total lower limb muscle strength (LLMS) in older women. DESIGN: observational cross-sectional study. METHODS: 119 community-dwelling older women were submitted to the ST and LLMS evaluation (isometric peak torque of eight muscle groups of the dominant lower limb). The capacity of the ST to discriminate older women with reduced LLMS was measured using ROC curve, followed by the posttest probability (PoTP) calculation. RESULTS: a ST score of 0.24 cm per cm of participant's height presents a sensitivity of 63.3%, specificity of 77%; enhances the PoTP from 48% to 72% for positive test and decreases the PoTP from 48% to 31% for negative test. CONCLUSION: the ST may complement the clinical screening of reduced LLMS in older women, given that it is a simple and quick low-cost test and allows the evaluation of each lower limb separately.

RESUMEN

Objective: To investigate whether lower limb muscle strength could be a risk factor for the first fall among nonfaller community-dwelling older adults. Method: Hip, knee, and ankle peak torque (PT) was measured with an isokinetic dynamometer in 101 older adults with no history of falls in the previous year. Next, the authors followed up the participants on a monthly basis by telephone contact to determine the occurrence of fall episodes over a period of 1 year. Multivariate logistic regression adjusted for confounding variables was applied to assess the relationship between falls and lower limb PT. Results: there was no association between lower limb PT and future falls (p > .05). Conclusion: Based on these results, it is important to identify other factors that predispose older adults with no history of falls to falling for the first time, so that early and effective preventive strategies may be elaborated.

RESUMEN

Background: Self-reported clinical worsening by people with Parkinson's disease (PD) during social distancing may be aggravated in Brazil, where the e/tele-health system is precarious. Objectives: This study aims to investigate self-reported changes in motor and non-motor aspects during social distancing in people with PD living in Brazil and to investigate the factors that might explain these changes. Methods: In this multicenter cross-sectional trial, 478 people with a diagnosis of idiopathic PD (mean age = 67, SD = 9.5; 167 female) were recruited from 14 centers distributed throughout the five geographical regions of Brazil. The evaluators from each center applied a questionnaire by telephone, which included questions (previous and current period of social distancing) about the motor and non-motor experiences of daily living, quality of life, daily routine, and physical activity volume. Results: Self-reported clinical worsening in non-motor and motor aspects of daily life experiences (Movement Disorder Society-Unified PD Rating Scale-parts IB and II-emotional and mental health, and fear of falling) and in the quality of life was observed. Only 31% of the participants reported a guided home-based physical activity with distance supervision. Perceived changes in the quality of life, freezing of gait, decreased physical activity volume, daily routine, and fear of falling explained the self-reported clinical worsening (P < 0.05). Conclusions: Self-reported clinical worsening in people with PD living in Brazil during social distancing can also be aggravated by the precarious e/tele-health system, as perception of decreased physical activity volume and impoverishment in daily routine were some of the explanatory factors. Considering the multifaceted worsening, the implementation of a remote multi-professional support for these people is urgent.

RESUMEN

INTRODUCTION: One of the main risk factor for falls is a history of falls itself. Henceforth, preventing a fall is an important strategy for the prevention of new ones. The objective of the present study was to determine whether personal self-perception questions and functional tests might represent risk factors for a fall during the year following a year without any falls among independent community-dwelling older adults, considering a period of 12 prospective months. METHODS: A total of 101 community-dwelling older adults without a fall in the previous year underwent an initial evaluation (sample characterization, self-perception questionnaire and functional tests) and monthly monitoring of prospective fall episodes by telephone contact. We determined the association between the occurrence of prospective falls (dependent variable) and personal questions and functional tests (independent variables) with multiple binary logistic regression adjusted for confounding variables. RESULTS: Only age (p = 0.005) and self-perception of general health (p = 0.019) showed association with the occurrence of prospective falls. CONCLUSION: Our results showed that the only factors bearing an association with the occurrence of prospective falls were age and general health self-perception, which demonstrates the importance of administrating self-perception measures in clinical practice or in epidemiological studies for the prevention of a fall during the year following a year without any falls in older adults.

RESUMEN

OBJECTIVE: The objective of this study was to determine the accuracy of 3 clinical tests (lateral step [LS], tandem gait [TG], and single-leg stance [SS]) in identifying older women with reduced hip abductor muscle strength and to determine the post-test probability of each test and of their combination in changing the certainty of diagnosis. METHODS: In this cross-sectional study, a total of 123 older women received clinical testing to obtain the variables LS height, time for TG execution, percentage of errors in TG, and time of permanence on SS and were tested for isometric hip abductor peak torque using an isokinetic dynamometer. Only the dominant lower limb was evaluated. Multiple linear regression analysis with adjustment was performed to determine the association among variables, followed by the receiver operating characteristic curve to identify clinical variables that can discriminate older women with reduced abductor muscle strength. Post-test probability was then calculated based on the receiver operating characteristic curve data. RESULTS: Although the 4 clinical variables showed correlation with abductor peak torque, only LS and TG time were able to discriminate reduced abductor muscle strength with low accuracy (area under the curve was between 0.5 and 0.7). However, the combination of LS and TG time increased post-test probability from 47% (prevalence of weakness in the population) to 76% when both tests were positive and reduced it from 47% to 18% when both tests were negative. CONCLUSION: The combination of the LS test and TG time is useful for the indirect assessment of hip abductor strength in community-dwelling older women. IMPACT: Hip abductor muscle strength is extremely important for function in older women. This study presents clinicians with simple, fast, and inexpensive methods for assessing hip abductor muscle strength.

RESUMEN

Safe street crossing is important for older adults' social inclusion. We assessed gait kinematic adaptation under different simulated street crossing conditions in older adults with Parkinson's disease (PD) and made comparisons with older adults without PD to understand how PD interferes in outdoor task performance, helping in the development of strategies to reduce road traffic accident risk. In 20 older adults without PD (control group - CG) and 20 with PD (GPD), we assessed usual gait (C1), gait during street crossing simulation (C2), and gait during reduced-time street crossing simulation (C3). Velocity, step length, and step, swing, stance, and double support time were analyzed. Spatiotemporal differences in gait between groups and conditions were analyzed. The GPD walked 16% slower in C1 and 12% slower in C2 and C3 than the CG. GPD also took 11% shorter steps in C1 and 9.5% shorter steps in C2. The double support time was 8.5% greater in C1. In intragroup comparisons, there were significant differences in all gait conditions. The CG showed increased velocity (C2 15% > C1; C3 13% > C2; C3 26% > C1), step length (C2 8% > C1; C3 5% > C2; C3 13% > C1), and swing time (C2 2% > C1; C3 3.7% > C2; C3 6% > C1), and decreased step time (C2 7.5% < C1; C3 8% < C2; C3 15% < C1), stance time (C2 1.3% < C1; C3 2.5% < C2; C3 3.6% < C1), and double support time (C2 6.3% < C1; C3 10.5% < C2; C3 16% < C1). GPD showed increased velocity (C2 19% > C1; C3 13.5% > C2; C3 29.7% > C1), step length, (C2 6% > C1; C3 7% > C2; C3 16% > C1), and swing time (C2 3% > C1; C3 3% > C2; C3 5.5% > C1) and decreased step time (C2 10.3% < C1; C3 7.7% < C2; C3 17% < C1), stance time (C2 1.7% < C1; C3 1.7% < C2; C3 3.4% < C1), and double support time (C2 7% < C1; C3 9.5% < C2; C3 16% < C1). Kinematic changes observed in the intergroup comparison show that participants with PD had lower velocity in all conditions. However, per the intragroup results, both participants with and without PD managed to significantly modify gait variables to attempt to cross the street in the given time. It is necessary to assess whether this increases fall risk by exposing them to road traffic accidents.

RESUMEN

BACKGROUND AND PURPOSE: With the increase in the percentage of the population in older adulthood, issues such as frailty syndrome need to be considered. The aim of the present study was to evaluate the ability of the Balance Evaluation Systems Test (BESTest) and center of pressure (COP) in their ability to discriminate between nonfrail, prefrail, and frail older adults. The proposed hypothesis is that frail older adults would show poorer performance in BESTest tasks and higher oscillation of COP on a force platform. METHODS: Sixty older adults 65 years or older were divided into 3 groups of 20: group 1, nonfrail; group 2, prefrail; and group 3, frail. The prefrail and frail identifications were made by Fried's 5 frailty phenotype criteria. Balance was assessed using the BESTest and a force platform in 6 positions: (1) fixed platform with eyes open; (2) fixed platform with eyes closed; (3) unstable platform with foam, with eyes open; (4) unstable platform, with eyes closed; (5) semitandem with eyes open; and (6) semitandem with eyes closed. RESULTS: Frail older adults had lower scores in all sections and in the total score of the BESTest, indicating worse performance in the tasks. However, on the force platform, the frail older adults did not show higher oscillations, having similar mean values when compared with the prefrail and nonfrail older adults, indicating similar behavior of COP. CONCLUSION: The BESTest seems to be more appropriate than a force plate for assessing postural control impairment and discriminating balance performance among frail, prefrail, and nonfrail older adults, providing information about different components of postural control rather than the force plate, which evaluates sensory orientation.

RESUMEN

There are still conflicting results regarding the association between grip and global muscle strength in older people. Therefore, the objective of the present study was to determine the association between grip strength and global muscle strength, as well as between grip strength and individual trunk, hip, knee and ankle muscle strengths. METHODS: Grip strength was assessed using a manual dynamometer, and trunk, hip, knee and ankle muscle strength with an isokinetic dynamometer, in order to obtain the global muscle strength variable, in 150 older men and women from the community. The association between grip and global muscle strength and between grip strength and the strength of each muscle group was determined through the Pearson correlation test, followed by multivariate linear regression adjusted for sex, age, body mass index, level of physical activity and number of comorbidities. RESULTS: A positive significant association was found between grip strength and global muscle strength in older people (r = 0.690; ß = 10.07; p < 0.001; R2 = 0.604), even after adjustment. There was also a low to moderate association between all the muscle groups and grip strength. However, when the model was adjusted, the relationship between grip strength and ankle dorsiflexor peak torque lost significance (p = 0.924). CONCLUSION: Grip strength can represent global muscle strength in younger older people in the community, even when confounding variables are considered in the statistical model. However, grip strength does not eliminate the need for specific assessment of different muscle groups, when indicated.

RESUMEN

BACKGROUND: With increases in life expectancy, it is important to understand the influence of aging on gait, given that this activity is related to the independence of older adults and may help in the development of health strategies that encourage successful aging in all phases of this process. RESEARCH QUESTION: To compare gait parameters with usual and fast speeds for independent and autonomous older adults throughout the aging process (60 to 102 years old), and also to identify which of the gait variables are best for identifying differences across the different age groups. METHODS: Two hundred older adults aged between 60 and 102 years were evaluated. The sample was divided into 3 age groups: 60 to 79 years, 80 to 89 years and 90 years and over. The analyzed gait variables were: speed (meters/s), cadence (steps/min), stride time (seconds), step length (centimeters), double support (percentage of the gait cycle), swing (percentage of the gait cycle), step length variability (CoV%) and stride time variability (CoV%). RESULTS: Group comparison regarding usual gait and fast gait revealed a significant difference in all gait variables. In addition, it can be seen that variables such as gait speed and step length showed greater effect sizes in intergroup comparison (usual gait: 0.48 and 0.47; fast gait: 0.36 and 0.40; respectively), possibly showing that these variables can better detect the changes observed with increasing age. CONCLUSION: There are differences in the gait performance of older adults from different age groups for usual and fast gait speeds, which is more evident regarding gait speed and step length variables. We recommend the use of usual gait for the identification of the effects of aging because, besides showing a higher effect size values it is more comfortable and requires less effort from older subjects.

RESUMEN

Introduction: The World Health Organization (WHO) has proposed to monitor intrinsic capacity (IC) in the older population as a public health strategy through the Integrated Care for Older People (ICOPE) program. Although the program has been developed based on solid concepts, scientific evidence on its practical applicability is still scarce. Objectives: To evaluate IC in Brazilian older adults, its progress over time, and its association with sociodemographic and health factors and outcomes. To evaluate the psychometric properties of the WHO/ICOPE screening tool. Methods: This is a prospective multicenter cohort study with a 36-month follow-up. We will recruit 3838 people aged ≥60 years, registered in the health care units included in the study by the participating centers. We will collect sociodemographic and health data and will administer tools to assess IC domains, both those provided for in the ICOPE screening tool and the sequence of confirmatory assessments provided for in the program. Participants will be reassessed every 6 months for 36 months. Expected results: To establish the profile of IC in the study population and to understand its progress and the variables associated with the clinical outcomes of interest. To reveal the diagnostic and psychometric properties of the WHO/ICOPE screening tool. The project is funded by the Brazilian National Council for Scientific and Technological Development (CNPq). Relevance: Understanding the potential use of the ICOPE public health strategy proposed by the WHO within the scope of the Brazilian Unified Health System (SUS) by integrating several research centers in the field of Geriatrics and Gerontology throughout Brazil.

Introdução: A Organização Mundial da Saúde (OMS) propõe o monitoramento da capacidade intrínseca (CI) da população idosa como estratégia de saúde pública por meio do Programa ICOPE (Integrated Care for Older People). Embora construído com base em conceitos sólidos, a evidência científica sobre a aplicabilidade prática da proposta ainda é escassa. Objetivo: Avaliar a capacidade intrínseca da população idosa brasileira, sua trajetória e sua associação com variáveis sociodemográficas, de saúde e desfechos. Avaliar as propriedades psicométricas da ferramenta de triagem da estratégia ICOPE da OMS. Metodologia: Coorte multicêntrica prospectiva com seguimento de 36 meses. Serão recrutadas 3.838 pessoas com 60 anos ou mais, cadastradas nas unidades de saúde incluídas no estudo pelos centros participantes. Serão coletados dados sociodemográficos e de saúde e aplicados instrumentos para avaliação dos domínios da CI, tanto aqueles previstos no instrumento de triagem do ICOPE quanto a sequência de avaliações confirmatórias previstas no programa. Os participantes serão acompanhados semestralmente ao longo de 36 meses. Resultados esperados: Estabelecer o perfil da CI na população estudada, entender a sua trajetória e as variáveis associadas aos desfechos clínicos avaliados. Revelar as propriedades diagnósticas e o perfil psicométrico da ferramenta de triagem do ICOPE da OMS. O projeto tem financiamento do Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq). Relevância: Compreensão sobre o potencial de utilização da estratégia ICOPE de saúde pública proposta pela OMS no âmbito do Sistema Único de Saúde (SUS) pela integração de diversos centros de pesquisa científica na área de Geriatria e Gerontologia de todo o Brasil.

RESUMEN

The aim of the present study was to investigate levels of physical activity and risk factors for inactivity in older adults living in an urban area in the interior of the Amazonas state, Brazil. Data were collected between 2013 and 2015 from 274 individuals 60 years of age or older who resided in the interior of the Brazilian Amazon. Sociodemographic, general health, functional capacity and physical performance were associated with self-referred physical activity level. A multivariate analysis, after adjustment, showed that being a man, having a body mass index above 27kg/m2, never having lived in riverside communities and having less than three associated chronic diseases were independent risk factors for low levels of physical activity among elderly residing in the interior of the Brazilian Amazon. Few studies have been conducted about the characteristics that are singular to this population. Our results suggest that the physical activity level and, consequently, the aging process of the elderly is influenced by where they have resided throughout their lives. Additionally, the results showed particular risk factors associated with low physical activity level among older adults residing in the interior of the state of Amazonas.
