Feasibility of a community-adapted multi-domain intervention for dementia prevention among older adults: a research protocol.

BACKGROUND

Multi-domain interventions effectively prevent dementia in clinical settings; however, their efficacy within local communities is unclear. This study assesses the feasibility of an adapted multi-domain intervention for dementia prevention in community-dwelling older adults.

METHODS

The single-arm trial enrolls 60 participants from two Obu City communities, Japan.

PRIMARY OUTCOME

participant retention in the adapted multi-domain intervention; secondary outcomes: health and implementation outcomes. Over 12 months, a team of researchers and public health nurse oversees the study in the first half, gradually shifting the management to public health nurses in the second half. Using the Framework for Reporting Adaptations and Modifications-Enhanced, the clinical programme is adjusted for the local community. It includes a 60-minute exercise and 30-minute group sessions, targeting lifestyle, diet, and social participation.

DISCUSSION

This pioneer study evaluates the feasibility of an adapted intervention programme for dementia prevention in a community setting. Challenges in disseminating dementia prevention programmes warrant further investigation into effective implementation as well as strategies and methods to appeal to the target population. Upon confirming this programme's feasibility, future studies can further evaluate its broader effectiveness.

TRIAL REGISTRATION

The protocol is registered with the Clinical Trials Registry (UMIN-CTR) of the University Hospital's Medical Information Network, under registration number UMIN000050581.
