ABSTRACT
Introduction: the aging that happens in the world is already a reality in remote and fast areas of the interior of Amazonas; with the population increasing each day more longevous, it is necessary to understand the aging process in these regions where the practice of physical activity is a reality, it was described the presence of life purpose in a group of older people who practice physical activity in the community. Objective: we investigated the presence of life purpose in older people who practiced physical activity before and during the covid-19 pandemic in the interior of Amazonas. Methods: this longitudinal study was conducted with 63 older people who practiced physical activity in a group before and during the covid 19 pandemic in the countryside of Amazonas. Sociodemographic and health characteristics were assessed, as well as well-being and life direction, through the life purpose questionnaire. Results: the elderly in this study have been followed since 2019; before the covid 19 pandemic struck the world, they practiced regular physical activity and had to temporarily suspend their training during the critical period of the pandemic. The group is composed mainly of older adults between the ages of 60 and 79; most are illiterate, have an income of not even one minimum wage, report living with someone, and say their vision as the regular or poor yet still present presence of life purpose and life direction. Conclusion: during the Covid-19 pandemic and social isolation, the elderly had a reduced perception of purpose in life, although they reported joy and satisfaction with life
ABSTRACT
Objetivo: Descrever a presença da prática de exercício físico e de função física em um grupo de idosos durante a pandemia por COVID-19 no interior do Amazonas. Métodos: Trata-se de um estudo transversal realizado com idosos ativos que realizavam exercício físico por pelo menos 3 vezes na semana por 50 minutos no interior do Amazonas. Avaliou-se a prática de exercício físico antes e durante a pandemia e aplicaram-se duas questões investigativas referente a COVID-19. Para avaliar a capacidade funcional e física aplicou-se o Short Physical Performance Battery (SPPB). Resultados: A amostra foi composta por 63 idosos ativos da comunidade. Destes, 31,8% (21) eram analfabetos, 74,2% (49) aposentados e 75,8 % (50) de baixa renda. No SPPB 27,3% (18) apresentaram total de 10 pontos e 14,29% (9) dos idosos realizam exercício físico acima dos minutos recomendados pela Organização Mundial da Saúde (OMS). Conclusão: Neste estudo nenhum fator durante a pandemia interferiu na prática de exercício físico e nem na capacidade funcional dos idosos que residem no interior do Amazonas.
ABSTRACT
ABSTRACT OBJECTIVE To estimate the association between vitamin D and the cognitive decline of older adults and evaluate whether this association is mediated by brain-derived neurotrophic factor (BDNF) serum concentration. METHODS Cross-sectional study nested in a population-based cohort. Of the 604 participants in the complementary examination of the EpiFloripa Study, 576 older adults (60 years or older) were eligible for the study. The outcome is cognitive decline evaluated by the Mini-Mental State Examination, the exposure is vitamin D, and BDNF is the mediator. The control variables are age, sex, per capita family income, and educational level. The direct effect of vitamin D and BDNF on cognitive decline and the indirect effect mediated by BDNF was evaluated using path analysis, with the estimation of standardized coefficients. RESULTS Among the participants, we observed a direct and positive effect of vitamin D on cognitive function (Coef: 0.06; 95%CI: 0.02 to 0.11; p < 0.001) and serum BDNF concentration (Coef: 21.55; 95%CI: 9.92 to 33.17; p = 0.002), i.e., the higher the vitamin D, the higher the cognitive function and serum level of BDNF. CONCLUSION There was an association between vitamin D on serum BDNF and on cognitive decline in older adults. Moreover, BDNF did not have an effect on cognitive decline, so BDNF was not a mediator of the vitamin D effect on cognitive decline.

This study aimed to present the method of the multi-center program of cognitive stimulation and rehabilitation known as "Oficina da Lembrança" (Memory Workshop), held at the University of Southern Santa Catarina, Federal University of Santa Catarina and Federal University of São Paulo. This project has assisted about 450 people aged 50 or older with memory complaints. Each session consists of one to three meetings/week (approximately 20 meetings/semester), with groups of 10 to 20 participants to carry out activities on computers, physical activity and individual oral reports of the experiences they had at the meetings (approximately 90 minutes). In the first and final six-monthly meeting, sociodemographic, health and behavioral variables, cognitive performance, functional disability and presence of depressive symptoms are collected. The project was implemented in 2006 and it is expected to continue. Programs like this are extremely important in society because they can provide benefits to the population, especially in terms of helping cognitive improvement, thus promoting health and socialization.
Este estudo objetivou apresentar o método do programa multicêntrico de estimulação e reabilitação cognitiva "Oficina da Lembrança", em execução na Universidade do Sul de Santa Catarina, Universidade Federal de Santa Catarina e Universidade Federal de São Paulo. O projeto já atendeu aproximadamente 450 pessoas com 50 anos ou mais de idade com queixas de memória. Cada sessão é composta de um a três encontros/semana (aproximadamente 20 encontros/semestre), com grupos de 10 a 20 participantes que realizam atividades em computadores, atividades físicas e relatos individuais orais sobre as experiências do encontro (aproximadamente 90 minutos). No primeiro e último encontro semestral são coletadas variáveis sociodemográficas, de saúde e comportamentais, desempenho cognitivo, capacidade funcional e presença de sintomas depressivos. O projeto foi implementado em 2006 e tem perspectiva de continuidade. Programas como este são extremamente importantes na sociedade, pois podem proporcionar benefícios à população, principalmente auxiliar na melhora cognitiva, promovendo saúde e sociabilização.
