Psychological states mediate the relationship between sleep quality and frailty among older adults.

ABSTRACT:

Objective

Frailty prevalence is high among older adults. While the association between poor sleep quality and frailty is established, the mediating role of psychological states (anxiety/depression) and the moderating influence of multidimensional factors (physiological conditions, dietary habits, and lifestyle factors) on this pathway remain unclear.
