Association between dietary diversity changes and frailty among Chinese older adults: findings from a nationwide cohort study.

ABSTRACT:

Background

Dietary diversity has been suggested as a potential preventive measure against frailty in older adults, but the effect of changes in dietary diversity on frailty is unclear. This study was conducted to examine the association between the dietary diversity score (DDS) and frailty among older Chinese adults.

Methods

A total of 12,457 adults aged 65 years or older were enrolled from three consecutive and nonoverlapping cohorts from the Chinese Longitudinal Healthy Longevity Survey (the 2002 cohort, the 2005 cohort, and the 2008 cohort).

We used 39 self-reported health items to assess frailty. Cox proportional hazard mo
