Here, we report that as community-dwelling pre-frail elderly individuals participated in a care center in Koshigaya City for six months and observed improvements in the Kihon checklist (KCL) total score, physical function, social isolation, depression, and CS-30. This study aimed to develop a predictive model that forecasts caregiving risk after six months of participation in Kayoinoba based on the initial assessment of care risk and motor function evaluation.
From 2016, This retrospective cohort study measured frailty using the KCL and motor function in Kayoinoba participants at the initial assessment (when participation began) and at the 6-month follow-up. Eligible participants were selected from regular participants at 41 local Kayoinoba locations. Of the 851 participants surveyed at their first participation session, 257 attended the second evaluation, had complete data, and were included in the analysis. The KCL is a self-evaluation survey comprising 25 questions about lifestyle and mental and physical functions. The timed up and go test (TUG), one-leg standing time, and 30-s chair stand test (CS-30) were used to assess motor function. Statistical analysis was conducted using the numerical analysis software MATLAB R2022a. After six months, KCL was used as an objective variable to assess the influence of each factor on KCL. Age, sex, and the first KCL, TUG, one-leg standing time test, and CS-30 were used as explanatory variables. Multiple regression analysis using a stepwise method was performed. To determine the relationships between the TUG and each evaluation item, first TUG and age, one-leg standing time test, CS-30, KCL total score, and KCL scores for undernutrition, dementia, self-isolation, depressed mood, and motor function were used as Spearman rank correlation coefficients. For each test, statistical significance was set p 5%.
The participants’ mean age was 74.8±6.3 years, with 39 men and 218 womem. Multiple regression analysis showed that the first KCL and TUG affected the KCL after six months. The regression formula is as follows:
KCL after six months (points) = first TUG (seconds) × 0.29 + first KCL (points) * 0.67 - 0.99
The model’s determination coefficient was 0.53 with an adjusted R2. A correlation between TUG and each item on the KCL was observed between one-leg standing time, and CS-30, age, and the basic checklist items related to self-isolation and motor function showed a moderate correlation.
A certain level of physical function is required for participants to continue attending our program, as reflected by the TUG test results.
The TUG could be an indicator for participating in the Kayoinoba, implementing our program, and improving KCL.
