The relationship between sleep quality and depressive symptoms in older adults: the mediated role of muscle strength (dynapenia).

ABSTRACT:

Background

The association between sleep quality and depressive symptoms was established, which could be varied by some mediators. Muscle strength might be a potential mediator for this association. The purpose of this study was to explore the mediating role of muscle strength in the relationship between sleep quality and depressive symptoms among the older individuals with or without dynapenia.

Methods

Three hundreds and nine older adults were allocated into two groups: dynapenia and non-dynapenia groups. The handgrip strength was assessed by the hand-held dynamometer. The quality of sleep and depressive symptoms were evaluated using Pittsburgh Sleep Quality Index and the 15-item Geriatric Depression Scale, respectively. The ProcessV3.3 was used to estimate the simple media
