[Effectiveness of a program promoting community activities for the prevention of frailty using a community...

We developed a program to promote community activities for preventing frailty using the Community-as-Partner model. We aimed to clarify whether or not participants' extent of practice relating to frailty prevention activities increased after the classroom, as well as the effectiveness of the program for preventing frailty.

The participants were recruited from among pre-frailty and frailty individuals in a cohort study of community-dwelling older adults. Thirty-two participants completed the classroom intervention. Thereafter, every three months, through a telephone survey, the participants were asked about the extent of practice regarding their frailty prevention activities. The Kihon Checklist and Japanese version of the Cardiovascular Health Study (J-CHS) frailty index were surveyed as outcome measures during the cohort study conducted six months before the classroom (baseline [BL]) as well as approximately one year after this intervention (follow-up [FL]). The changes in the outcome measures between the BL and FL in the intervention group were compared to those in the control group matched by the propensity score.

The frailty prevention activities saw a maximum increase around six to nine months after the classroom. The J-CHS frailty index showed a group × time-of-survey significant interaction (F = 6.531, p=0.012) and significantly decreased from 1.3 at BL to 0.8 at FL in the intervention group (p=0.009).

The practice of activities relating to frailty prevention increased after the classroom, and the participants also showed improvements in their physical frailty. The present program seems likely to be effective preventing frailty.
