Association between tooth loss and frailty among Chinese older adults: the mediating role of dietary diversity.

ABSTRACT:

Background

This study aimed to examine the association between tooth loss and frailty among Chinese older adults and the mediating role of dietary diversity in this association.

Methods

Data from five waves of the Chinese Longitudinal Healthy Longevity Survey conducted between 2005 and 2018 were used. Path analyses were employed to assess both concurrent and cross-lagged relationships between tooth loss and frailty index while accounting for intrapersonal correlation. Furthermore, the mediation effect of dietary diversity was also examined.

Results

In concurrent models, severe tooth loss was associated with frailty after adjusting for demographic characteristics (odds ratio [OR] = 1.82, p < 0.001). The OR of frailty for severe tooth loss was only slightly decreased to
