Effects of a community disability prevention program for frail older adults at 48‐month follow up

Aim The present prospective study was carried out to determine whether participation in community-based intervention studies exerted a positive impact on disability prevention in older adults with physical frailty. Methods A total of 514 community-dwelling older adults (aged ≥65 years) with physical frailty who had undergone baseline assessment and participated in community-based intervention studies (participants) or did not (non-participants) were included in the present study. Non-participants were selected through propensity score matching, to balance potential covariates at baseline. Disability incidence was followed up at 48 months as a main outcome. Demographic data (age, sex and medical history), global cognitive function, grip strength, walking speed, and blood test results including serum albumin and brain-derived neurotrophic factor at baseline were included as covariates. Results Disability incidence rates differed significantly between participants (11.3%) and non-participants (19.8%) of community-based intervention studies during the 48-month follow-up period (P = 0.007). Participation in community-based intervention studies (hazard ratio 0.55, 95% confidence interval 0.35–0.88) was significantly associated with the incidence of disability in older adults with physical frailty. Conclusions Participation in community-based intervention studies could reduce the incidence of disability in older adults with physical frailty. Thus, strategies designed to increase the number of participants in community-based intervention programs should be considered in community-based approaches for the prevention of disability in older adults with physical frailty.
