Social isolation due to COVID-19: impact on loneliness, sedentary behavior, and falls in older adults.

OBJECTIVES: The World Health Organization has recommended social isolation to prevent the transmission of COVID-19. Thus, feelings of loneliness, sedentary behavior, and predisposition to falls have been reported more often due to the adoption of social isolation, especially for older adults. The objective of this study was to compare older adults' loneliness, sedentary behavior, and occurrence of falls before and during social isolation due to the pandemic as well as to analyze the association of loneliness with sedentary lifestyle and falls in older adults. METHOD: Retrospective analytical study conducted through an online survey with older adults from Brazilian states in social isolation, approved by the Research Ethics Committee (number 32168920.0.0000.0068). RESULTS: There was a significant increase in loneliness and sedentary behavior during social isolation (p-value < 0.05 for both), but no increase was observed for falls (p-value = 0.615). There was no correlation between the outcomes, nor was there a correlation between the outcomes and the number of days in social isolation. CONCLUSION: The results of this research show that adoption of social isolation due to the COVID-19 pandemic brought an increase in sedentary behavior and loneliness for older adults but had no effect on the number of falls.

Immersive Virtual Tasks With Motor and Cognitive Components: A Feasibility Study With Young and Older Adults.

OBJECTIVE: To analyze the feasibility, safety, and acceptability of immersive virtual tasks. METHODS: The authors recruited 11 young adults and 10 older adults. The participants performed three virtual reaching tasks while walking on a virtual path. The descriptive analysis and comparison between participants were performed using the Mann-Whitney U test and chi-square test for nonparametric and nominal variables, respectively. The authors also used analysis of variance for a between-groups comparison for normal variables. RESULTS: Twenty percent of older adults and 81.8% of young adults completed all three tasks (chi-square test; p = .005). Both groups reported minor symptoms, with no significant differences. The older adults were more motivated to practice the tasks (Mann-Whitney U test; p = .015) and would be more likely to suggest them to others (chi-square test; p = .034). CONCLUSION: All three tasks were feasible for young adults. All participants, except for one, had cybersickness. The symptoms were mostly mild and subsided once the interaction was complete.
