Association among race/color, gender, and intrinsic capacity: results from the ELSI-Brazil study

OBJECTIVE: To investigate associations among race/color, gender, and intrinsic capacity (IC) (total and by domains) in middle-aged and older adults from a Brazilian cohort. As a secondary objective, we investigate these associations across Brazilian regions. METHODS: This is a cross-sectional study conducted with baseline data from the 2015–2016 Brazilian Longitudinal Study of Aging (ELSI-Brazil). IC was investigated via cognitive (verbal fluency), physical (gait velocity/handgrip), and psychosocial (Center for Epidemiological Studies Depression) domains. Moreover, IC sensory domain was evaluated via self-reported sensory disease diagnoses (vision and/or hearing impairment) and race/color was identified via self-reported criteria. RESULTS: We evaluated a total of 9,070 participants (aged ≥ 50 years). Black and Brown participants were 80% and 41% more likely to show a worse IC cognitive domain than white controls, respectively (OR = 1.80, 95%CI: 1.42–2.28, p < 0.001 and OR = 1.41, 95%CI: 1.21–1.65, p < 0.001). Moreover, Black and Brown women had almost a threefold greater chance of showing a worse IC than white men (OR = 2.91, 95%CI: 1.89–4.47, p < 0.001 and OR = 2.51, 95%CI: 2.09 - 3.02, p < 0.001) and a 62% (OR = 1.62, 95%CI: 1.02–2.57) and 32% (OR = 1.32, 95%CI: 1.10–1.57) greater risk of falling below our IC score cutoff point than white women. We found the greatest differences in the Brazilian South, whereas its North showed the lowest associations among race/color, gender, and IC. CONCLUSION: IC racial and gender disparities reinforce the need for public health policies to guarantee equality during aging. Promoting greater access to good health care requires understanding how racism and sexism can contribute to health inequities and their consequences in different Brazilian regions

Prevalence of dynapenia and overlap with disability, depression, and executive dysfunction

OBJECTIVE: This study aims to investigate handgrip strength and dynapenia prevalence among older adults stratified by Brazilian macroregions. Additionally, we aim to evaluate the overlap between dynapenia and Instrumental Activities of Daily Living (IADL) disability, depression, and executive dysfunction on a national basis and by each Brazilian macroregion. METHODS: This cross-sectional analysis was based on data from the Brazilian Longitudinal Study of Aging (ELSI-Brazil). A multistage cluster sample design was used, with a representative population-based study of non-institutionalized community-dwelling Brazilians aged ≥ 50 years from 70 municipalities across all five macroregions of the country. The outcome variable was dynapenia. Covariables were IADL disability, depression, and executive dysfunction. The Brazilian macroregions were used for stratification. In addition, the following additional variables were included: age group, gender, education level, macroregions (North, Northeast, Southeast, South, and Midwest), self-reported health, multimorbidity, and falls. RESULTS: A total of 8,849 (94%) of the sample provided complete information for the handgrip strength assessment and were included in this analysis. Dynapenia prevalence was higher in North and Northeast regions (28.5% and 35.1%, respectively). We identified statistically significant differences between different macroregions for dynapenia, IADL disability, and verbal fluency, with worse values in the North and Northeast regions. In the North and Northeast macroregions, nearly half of the subjects that presented executive dysfunction and IADL disability also had dynapenia. There was a more significant overlap in the prevalence of all four conditions in the North and Northeast regions (4.8% and 5.5%, respectively), whereas the overlap was smaller in the South (2.3%). There was also a smaller overlap in the prevalence of dynapenia and depression in the South (5.8%) compared with other macroregions. CONCLUSIONS: Macroregions in Brazil exhibit marked differences in the prevalence of dynapenia and in its overlap with IADL disability, depression, and executive dysfunction

Verbal fluency in Alzheimer's disease, Parkinson's disease, and major depression

OBJECTIVE: To compare verbal fluency among Alzheimer's disease, Parkinson's disease, and major depression and to assess the sociodemographic and clinical factors associated with the disease severity. METHODS: Patients from an outpatient university center with a clinical diagnosis of Alzheimer's disease, Parkinson's disease or major depression were studied. Severity was staged using the Hoehn & Yahr scale, the Hamilton Depression scale and the Clinical Dementia Rating for Parkinson's disease, major depression, and Alzheimer's disease, respectively. All subjects were tested with the Mini-Mental State Examination, the digit span test, and the verbal fluency test (animals). We fit four types of regression models for the count variable: Poisson model, negative binomial model, zero-inflated Poisson model, and zero-inflated negative binomial model. RESULTS: The mean digit span and verbal fluency scores were lower in patients with Alzheimer's disease (n = 34) than in patients with major depression (n = 52) or Parkinson's disease (n = 17) (p<0.001). The average number of words listed was much lower for Alzheimer's disease patients (7.2 words) compared to the patients presenting with major depression (14.6 words) or Parkinson's disease (15.7 words) (KW test = 32.4; p<0.01). Major depression and Parkinson's disease groups listed 44% (ROM = 1.44) and 48% (ROM = 1.48) more words, respectively, compared to those patients with Alzheimer's disease; these results were independent of age, education, disease severity and attention. Independently of diagnosis, age, and education, severe disease showed a 26% (ROM = 0.74) reduction in the number of words listed when compared to mild cases. CONCLUSIONS: Verbal fluency provides a better characterization of Alzheimer's disease, major depression, and Parkinson's disease, even at later stages

Acute exercise improves cognition in the depressed elderly: the effect of dual-tasks

OBJECTIVE: The goal of this study was to assess the acute effect of physical exercise on the cognitive function of depressed elderly patients in a dual-task experiment. INTRODUCTION: Physical exercise has a positive effect on the brain and may even act as a treatment for major depressive disorder. However, the effects of acute cardiovascular exercise on cognitive function during and after one session of aerobic training in elderly depressive patients are not known. METHODS: Ten elderly subjects diagnosed with major depressive disorder performed neuropsychological tests during and after a moderate physical exercise session (65-75%HRmax). A Digit Span Test (Forward and Backward) and a Stroop Color-Word Test were used to assess cognitive function. The elderly participants walked on an electric treadmill for 30 minutes and underwent the same cognitive testing before, during, immediately after, and 15 minutes after the exercise session. In the control session, the same cognitive testing was conducted, but without exercise training. RESULTS: The results of the Digit Span Test did not change between the control and the exercise sessions. The results of the Stroop Color-Word Test improved after physical exercise, indicating a positive effect of exercise on cognition. CONCLUSIONS: These data suggest that the cognitive functions of depressed elderly persons, especially attention and inhibitory control, are not impaired during and after an acute session of physical exercise. In contrast, the effect of dual-tasks showed beneficial results for these subjects, mainly after exercise. The dual-task may be a safe and useful tool for assessing cognitive function

Factors associated with adherence to sports and exercise among outpatients with major depressive disorder

Introduction: Individuals with major depressive disorder (MDD) face more barriers to engagement in sports and exercise interventions. Evaluating clinical and demographic factors associated with adherence to sports and exercise among MDD outpatients could support development of new options and strategies to increase their participation. Methods: In a cross-sectional study, 268 depressed outpatients were evaluated (83.51% females; mean age = 50.74 [standard deviation {SD} = 10.39]). Sports and exercise participation were assessed using a question about participation frequency during the previous month. Clinical and demographic factors were evaluated. Linear regression was used to identify predictors of participation in sports and exercise. Results: MDD patients with mild symptoms of depression (odds ratio [OR] = 2.42; 95% confidence interval [95%CI] 1.00, 5.88; p = 0.04) and patients with mild to moderate symptoms (OR = 3.96; 95%CI 1.41, 11.15; p = 0.009) were more likely to engage regularly in sports and exercise than patients with more severe depression. Moreover, smoking (OR = 0.23; 95%CI 0.67, 0.80; p = 0.007) and being divorced (OR = 0.22; 95%CI 0.57, 0.86; p = 0.03) were associated with lower rates of engagement in sports and exercise. Conclusion: Our findings indicate a significant association between clinical and demographic factors and participation in sports and exercise among MDD outpatients

Avaliação da aptidão cardiorrespiratória por meio de protocolo submáximo em idosos com transtorno de humor e doença de Parkinson

CONTEXTO: Evidências demonstram benefícios para a saúde mental com o treinamento aeróbico orientado em percentuais do VO2max, indicando a importância dessa variável para a prática clínica. OBJETIVO: Validar um método para estimar o VO2max por meio de um protocolo submáximo em idosos com diagnóstico clínico de transtorno depressivo maior (DM) e doença de Parkinson (DP). MÉTODOS: A amostra foi composta por 18 pacientes (64,22 ± 9,92 anos; sete pacientes com DM e 11 com DP). Foram realizadas três avaliações: I) estadiamento da doença, II) mensuração direta de VO2max e III) teste de esforço submáximo. Foi realizada regressão linear para verificar a precisão de estimativa do VO2max estabelecido na ergoespirometria pelo VO2max predito no teste submáximo. Também foi analisada a concordância de Bland-Altman entre os procedimentos. RESULTADOS: A análise de regressão mostrou que os valores de VO2max estimados pelo protocolo submáximo associam-se com o VO2max medido, tanto no valor absoluto (R² = 0,65; EPE = 0,26 ; p < 0,001) quanto no relativo (R² = 0,56; EPE = 3,70; p < 0,001). A análise de concordância de Bland-Altman mostrou boa associação entre as duas medidas. CONCLUSÃO: O VO2max predito por meio do protocolo submáximo demonstrou satisfatória validade de critério e simples execução comparado à ergoespirometria.BACKGROUND: Evidence has shown benefits for mental health through aerobic training oriented in percentage of VO2max, indicating the importance of this variable for clinical practice. OBJECTIVE: To validate a method for estimating VO2max using a submaximal protocol in elderly patients with clinically diagnosis as major depressive disorder (MDD) and Parkinson's disease (PD). METHODS: The sample comprised 18 patients (64.22 ± 9.92 years) with MDD (n = 7) and with PD (n = 11). Three evaluations were performed: I) disease staging, II) direct measurement of VO2max and III) submaximal exercise test. Linear regression was performed to verify the accuracy of estimation in VO2max established in ergospirometry and the predicted VO2max from the submaximal test measurement. We also analyzed the correlation between the Bland-Altman procedures. RESULTS: The regression analysis showed that VO2max values estimated by submaximal protocol associated with the VO2max measured, both in absolute values (R² = 0.65; SEE = 0.26; p < 0.001) and the relative (R² = 0.56; SEE = 3.70; p < 0.001). The Bland-Altman plots for analysis of agreement of showed a good correlation between the two measures. DISCUSSION: The VO2max predicted by submaximal protocol demonstrated satisfactory criterion validity and simple execution compared to ergospirometry

Relação entre esporte, resiliência, qualidade de vida e ansiedade

BACKGROUND: The practice of sports has beneficial effects on cardiorespiratory and muscle systems, behavioral function, and mental health. However, the influence of elite sports on the development of resilience is not known. OBJECTIVES: The objective of the present study was to compare resilience, quality of life, and anxiety in ex-athletes of artistic gymnastic and other sports with non-athletic individuals. METHODS: Ex-artistic gymnastics athletes (n = 17), ex-athletes of other sports (n = 15), and non-athletic individuals (n = 30) were recruited. Structured anamneses as well as depression, anxiety, resilience and quality of life scales were applied in all groups. RESULTS: Significant difference between groups were found in resilience (p = 0.001), anxiety (p = 0.049), general health status (p = 0.044), and emotional aspects of quality of life (p = 0.002). Ex-athletes showed greater resilience and better quality of life regarding to emotional aspects than non-athletes. DISCUSSION: Sport seems to contribute to the development of a more resilient profile and better quality of life.CONTEXTO: A prática de esportes apresenta efeitos benéficos para o sistema cardiorrespiratório e muscular, para a função comportamental e para a saúde mental. Entretanto, não se sabe o papel do esporte de alto nível na construção de perfis resilientes.
