Abstract

Aim: This study aimed to ascertain the prevalence of frailty during the pandemic and to determine factors associated with changes in frailty status.

Methods: In May-June of 2020-2022, we assessed the frailty of 549 participants using the Kihon Checklist. Furthermore, we classified participant residences as urban, suburban, and rural and investigated participants' engagement in hobbies and community activities in 2020 and 2022. Cochran's Q test was used to analyze the proportions of frailty status. Subsequently, we conducted a binomial logistic regression analysis with the improvement/deterioration of frailty status from 2020 to 2022 as the dependent variable, and engagement in hobbies and community activities as the independent variables.

Results: Significant changes were observed among participants in urban areas, where an increase in pre-frailty and a decrease in robust individuals from 2020 to 2021 were noted. Focusing on item no. 17 (going out), the decreasing frequency had recovered by 2022 in the group of all groups. Continued engagement in only hobbies or only community activities, and continued engagement in both were associated with remained robust/frailty-status improvement. Moreover, not engaging in either hobbies or community activities was associated with remained frail/frailty-status deterioration.

Conclusions: During the early stages, the COVID-19 pandemic impacted the frailty of older adults in densely populated areas. The results also suggest an attenuation in the decline in older adult activity in 2022. Continuous engagement in hobbies and community activities was crucial for improving and preventing deterioration in frailty status during the COVID-19 pandemic. Geriatr Gerontol Int 2024; 24: 40-47.
