ABSTRACT 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. racecolor race color (IC domains middleaged middle aged cohort objective regions crosssectional cross sectional 20152016 2015 2016 2015–201 ELSIBrazil.

RESUMO Objetivos: Os objetivos do presente estudo foram avaliar o comportamento sedentário e os níveis de atividade física antes e durante da pandemia de COVID-19 em indivíduos saudáveis e com diagnóstico autorreportado de ansiedade e/ou depressão e identificar os facilitadores e barreiras para a prática de atividade física nessas populações. Métodos: Trata-se de uma pesquisa de corte transversal baseada em um questionário de autorrelato aplicado durante o período de pandemia da COVID-19. Resultados: Na amostra total (N = 1.285), a prevalência de comportamento sedentário (>8 horas/dia) aumentou em 25% durante o isolamento social. O isolamento social aumentou o tempo sedentário e diminuiu os níveis de atividade física em indivíduos saudáveis, com ansiedade e/ou depressão autorreportada. Nos dois grupos, os facilitadores mais prevalentes foram a atividade física supervisionada (antes da pandemia) e as atividades e equipamentos para a prática em casa (durante a pandemia). As barreiras mais prevalentes foram a falta de tempo para realizar atividades físicas (antes da pandemia) e os locais inacessíveis ou distantes para a prática (durante a pandemia). Conclusão: A pandemia de COVID-19 está relacionada a aumento do comportamento sedentário e redução dos níveis de atividade física. Mudanças significativas nas barreiras percebidas e facilitadores ao exercício foram observadas durante o período de isolamento social.

ABSTRACT Objectives: The objectives of the present study were to assess sedentary behavior and physical activity levels before and during the COVID-19 pandemic in healthy individuals and in those with self-reported diagnosis of anxiety and/or depression, and also identify facilitators and barriers to physical activity in these populations. Methods: This is a cross-sectional survey based on a self-report questionnaire applied during the COVID-19 pandemic period. Results: In the total sample (N = 1,285) the prevalence of sedentary behavior (>8 hours/day) increased by 25% during social isolation. Social isolation increased sedentary time and decreased physical activity levels in healthy individuals and in those with self-reported diagnosis of anxiety and/or depression. In both groups, the most prevalent facilitators were supervised physical activity (before the pandemic) and activities and equipment to practice at home (during the pandemic). The most prevalent barriers were the lack of time to perform physical activities (before the pandemic) and inaccessible or distance places to practice (during the pandemic). Conclusion: The COVID-19 pandemic is related to an increased sedentary behavior and reduced physical activity levels. Significant changes in perceived barriers and facilitators to exercise were observed during the social isolation period.

RESUMO. A capacidade aeróbica diminui significativamente ao longo da vida, começando com a idade de 30 anos e acelerando a partir dos 60 anos, onde se prevê um declínio de 17% por década. Objetivo: Investigar a associação entre a capacidade aeróbica medida e o risco de desenvolvimento de comprometimento cognitivo leve (CCL), DA leve e moderado em idosos, considerando as classificações de risco de perda funcional para o teste do STEP. Métodos: Nesse estudo de corte-transversal, foram avaliados 93 idosos (>60 anos) (saudáveis=36; CCL=18, DA=39). Para acessar a capacidade aeróbica foi utilizado o teste de STEP e o estado cognitivo global foi medido através do MEEM. Os grupos foram divididos em relação às classificações de risco de perda funcional em abaixo ou acima do ponto de corte padronizado para idosos. Resultados: Idosos incluídos no grupo de risco de perda funcional tinham aproximadamente dez a catorze vezes mais chances de serem diagnosticados com DA leve (O.R:10.7; p=0.001) e moderado (O.R.=14.7; p=0.002), do que os seus pares mais bem condicionados. Menores níveis de capacidade aeróbica também foram associados com o diagnostico de CCL (O.R=4.5; p=0.05), entretanto apenas após controle por idade, escolaridade e sexo. Na amostra total (N=93) houve uma associação entre a capacidade aeróbica e o MEEM (R2=0.35; p<0.001) depois de controlado pelas variáveis confundidoras. Conclusão: Idosos que se encontram dentro da classificação de risco de perda funcional medida através do teste de STEP possuem maiores chances de desenvolverem CCL, Alzheimer leve e moderado mesmo após controle por idade, sexo e escolaridade.

ABSTRACT. Aerobic capacity declines significantly throughout life, beginning at the age of 30 years and accelerating from 60 years, where a decline of 17% per decade is expected thereafter. Objective: To investigate the association between aerobic capacity and a diagnosis of mild cognitive impairment (MCI), mild AD or moderate AD in older adults, considering the risk classification of functional loss of the Step test. Methods: In this cross-sectional study, 93 patients (age >60 years) were evaluated (Healthy=36; MCI=18, AD=39). The step test was used to assess aerobic capacity, while overall cognitive status was measured using the MMSE. The groups were divided according to the risk classifications of functional loss into below or above the standard cut-off point for aerobic capacity. Results: Subjects in the functional loss risk group were approximately ten to fourteen times more likely to be diagnosed with mild (OR:10.7; p=0.001) or moderate (OR.=14.7; p=0.002) AD than their fitter counterparts. Low aerobic fitness was also associated with the MCI condition (OR=4.5; p=0.05), but only after controlling for educational level, age and sex. In the overall sample (N=93), there was an association between aerobic capacity and MMSE performance (R2=0.35; p<0.001) after controlling for confounding variables. Conclusion: low aerobic capacity was associated with cognitive decline, and older adults at risk of functional loss on the STEP test had greater chance of being diagnosed with MCI or AD after controlling for age, sex and education.
