Effects of social distancing provoked by COVID-19 pandemic in the functional capacity and cognitive function in nonagenarians and centenarians.

ABSTRACT

INTRODUCTION: Due to the rapid advance of coronavírus SARS-CoV-2 (COVID-19) pandemic in 2020, social distancing was the main way to reduce the transmission of the virus. Although this measure was efficient and necessary, the social distancing had severe consequences for physical function, mainly in older individuals. Thus, the aim of this study was to investigate the effects of social distancing in the functional and cognitive capacity of community-dwelling oldest-old adults. METHODS: The present study is part of a larger prospective cohort study. Fifteen participants aged 90 years old or older were assessed in the 8-foot-timed-up-and-go test (8-footTUG), sit-to-stand-up test (STS), handgrip strength test (HGS), Mini Mental State Examination (MMSE), Katz Index and Lawton Scale before and after one year of social distancing. RESULTS: A significant worsening in the 8-footTUG and MMSE score was observed, while there were no significant changes in the other variables. When analyzing the decreases in relation to previous functional capacity, it was observed that individuals categorized as dependent by STS cut-off points had the worst decreases in functional capacity. CONCLUSION: The social distancing provoked by COVID-19 pandemic negatively affected the 8-footTUG and cognition. Moreover, individuals dependents showed greater decline in their functional capacity.
