OBJETIVO: Este estudo teve como propósito analisar a capacidade da velocidade da marcha em identificar idosos com medo de cair. METODOLOGIA: Trata-se de estudo transversal analítico, realizado com amostra de 60 idosos da comunidade. Os dados foram obtidos por meio de questionário estruturado, análise da velocidade da marcha para percorrer a distância de 4,6 m e do medo de cair, avaliado pela escala de Autoeficácia de Quedas. A capacidade da velocidade da marcha em identificar idosos com medo de cair foi determinada por meio de regressão linear múltipla, com nível de significância p<0,05 e IC 95%. RESULTADOS: Em relação à velocidade da marcha, a média foi de 0,71 (± 0,21) m/s, enquanto que para a escala de Autoeficácia de Quedas a média do escore foi de 24,85 (± 6,68). Na análise de regressão linear múltipla, o escore total da escala de Autoeficácia de Quedas permaneceu significativamente associado (R²= 0,35) com a depressão autorrelatada, a limitação funcional para atividades básicas da vida diária e a velocidade da marcha. CONCLUSÃO: A velocidade da marcha, além da depressão autorrelatada e limitação funcional para atividades básicas da vida diária, têm capacidade de identificar idosos com medo de cair. Desta forma, a investigação das condições de saúde nessa população pode ser útil para detectar o medo de cair e identificar que cuidados e intervenções seriam prioritários para melhorar a funcionalidade e qualidade de vida desses idosos.
We examined associations between adverse childhood experiences (ACEs) and shorter telomere length (TL) in 83 older women, including 42 women with less than secondary education and 41 with secondary or more education in a city of Northeast Brazil, a region with substantial socioeconomic inequalities. The low education sample was selected from a representative survey at local neighborhood health centers, while the high education group consisted of a convenience sample recruited by advertising in community centers and centers affiliated with the local university. Relative leukocyte TL was measured by quantitative polymerase chain reaction from blood samples. ACEs were self-reported. Spline linear regression was fitted to assess the strength of the associations between ACEs and TL. Among women with low education, median TL was 1.02 compared with 0.64 in the high education group (p = 0.0001). Natural log-transformed T/S ratio as the dependent variable was used in analysis. Women with low education had been exposed to more ACEs, and among them those experiencing two or more ACEs had longer TL than women exposed to ≤1 ACEs (p = 0.03); among women with high education, this difference was not significant (p = 0.49). In analyses adjusted by age, education, and parental abuse of alcohol, the linear trend of higher TL with increasing ACEs was confirmed (p = 0.02), and the mean difference in TL between groups remained significant (p = 0.002). The unexpected positive relationship between low education and ACEs with TL suggests that older adults who have survived harsh conditions prevailing in Northeast Brazil have the longest TL of their birth cohort.
Aim To assess the reliability and the validity of Portuguese- and Spanish-translated versions of the video-based short-form Mobility Assessment Tool in assessing self-reported mobility, and to provide evidence for the applicability of these videos in elderly Latin American populations as a complement to physical performance measures. Methods The sample consisted of 300 elderly participants (150 from Brazil, 150 from Colombia) recruited at neighborhood social centers. Mobility was assessed with the Mobility Assessment Tool, and compared with the Short Physical Performance Battery score and self-reported functional limitations. Reliability was calculated using intraclass correlation coefficients. Multiple linear regression analyses were used to assess associations among mobility assessment tools and health, and sociodemographic variables. Results A significant gradient of increasing Mobility Assessment Tool score with better physical function was observed for both self-reported and objective measures, and in each city. Associations between self-reported mobility and health were strong, and significant. Mobility Assessment Tool scores were lower in women at both sites. Intraclass correlation coefficients of the Mobility Assessment Tool were 0.94 (95% confidence interval 0.90–0.97) in Brazil and 0.81 (95% confidence interval 0.66–0.91) in Colombia. Mobility Assessment Tool scores were lower in Manizales than in Natal after adjustment by Short Physical Performance Battery, self-rated health and sex. Conclusions These results provide evidence for high reliability and good validity of the Mobility Assessment Tool in its Spanish and Portuguese versions used in Latin American populations. In addition, the Mobility Assessment Tool can detect mobility differences related to environmental features that cannot be captured by objective perfor mance measures.
IntroductionMobility decline compromises functionality and quality of life in old age. Life-Space Assessment (LSA) evaluates mobility considering interaction between person and environment. The International Classification of Functioning, Disability and Health (ICF) is a reference to identify and categorise the personal and environmental contextual factors associated to the LSA. Our objective is identifying contextual factors that may influence life-space mobility of older community-dwelling adults based on ICF.Methods and analysisA systematic review of literature will be performed to identify studies published between 1 January 2001 and 10 May 2017 which investigates life-space mobility among older adults. Keywords will be entered into the electronic databases of MEDLINE (PubMed), EMBASE (OVID), CINHAL (EBSCO), Cochrane Central Register of Controlled Trials Cochrane Central (OVID), PsycINFO (EBSCO) and COCH (OVID). Five investigators will work on search databases and standardised screening of the articles. Mobility predictors will be separated into personal and environmental aspects, according to the ICF model. The results will be reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement, and then a meta-analysis will be performed, if applicable.DiscussionKnowledge about life-space mobility in community-dwelling older adults by examining related risk and protective aspects may help practitioners better approach older adults’ mobility and prevent their decline in old age. Furthermore, researchers will have more clues for investigations into factors related to life-space mobility.Trial registration numberCRD42017064552.
This study assessed whether telomere length is related to chronic conditions, cardiovascular risk factors, and inflammation in women aged 65 to 74 from Northeast Brazil. Participants were selected from two sources, a representative sample of the International Mobility in Aging Study (n = 57) and a convenience sample (n = 49) recruited at senior centers. Leukocyte telomere length was measured by quantitative polymerase chain reaction from blood samples in 83 women. Natural log-transformed telomere/single copy gene ratio was used as the dependent variable in the analysis. Blood analyses included inflammatory markers (high-sensitivity C-reactive protein and interleukin-6), total, low-density lipoprotein and high-density lipoprotein cholesterol, triglycerides, glucose and glycosylated hemoglobin. Self-rated health, chronic conditions, cardiovascular risk factors and inflammatory markers were not associated with telomere length. No significant independent association was found between telomere length and anthropometric measures or blood markers, even after adjusting for age, education and adverse childhood events among these older women in Northeast Brazil. Our results did not confirm the hypothesis that chronic conditions, cardiovascular risk factors or inflammation are associated with shorter telomere length in these women who have exceptional survival relative to the life expectancy of their birth cohort.
