Abstract
In response to the interruption of continuous group activities during the coronavirus pandemic, we conducted a basic checklist and semi-structured interview-style survey on the status of daily life functions for those who had not been certified as requiring long-term care or were not eligible for such certification under the longterm care insurance system as of March 2020. The demographics of the survey targets (50 respondents) were as follows: male: 31, female: 19; young-old: 13 (22.0%), oldest-old: 37 (78%); and group participants: 18 (36.0%), nonparticipants: 32 (64.0%). Among those who had interrupted continuous group activities for one year, about 10% of the oldest-old were in need of support or care. Those with a BMI of less than 18.5 (underweight) or more than 25.0 (overweight) were more likely to be non-participants in groups and tended to be negatively impacted in terms of social participation, mental health, and cognitive function. Regardless of their care needs or BMI status, more than 90% of those surveyed reported that their contact with society had decreased. We saw a tendency for people who are prone to psychological anxiety to have a BMI of less than 18.5 (underweight) due to reduced contact with society and fewer opportunities to talk with others. In one year without continuous frailty intervention, approximately 10% of the patients progressed to the state of requiring nursing care, suggesting the need for continuous frailty prevention measures.
