Association between frailty recovery and dietary variety among community-dwelling older Japanese adults: a longitudinal study from 2023 to 2024.

ABSTRACT:

Background/objectives

Although the associations between frailty and nutrition have been reported, no studies have focused on frailty recovery in relation to dietary diversity. This study aimed to clarify the association between frailty recovery and dietary variety, assessed using the Dietary Variety Score (DVS), over a 1-year period.

Methods

A prospective cohort study conducted in City A, Tochigi prefecture, Japan, included 353 individuals aged 73 and 78 years in 2023 who responded to surveys in both 2023 and 2024. The Kihon Checklist (KCL) and DVS were used for assessments. According to the KCL results, participants who were robust in both years or who improved from frailty or pre-frailty in 2023 to robust in 2024 were classified as the "robust-maintained/-recovered group,"
