ABSTRACT
BACKGROUND:
Older patients with chronic heart failure (CHF) are prone to insomnia. Studies have shown that insomnia affects the onset of cognitive frailty and is also strongly associated with depressive symptoms and social support. However, information on how these factors interact to influence cognitive frailty remains underexplored.OBJECTIVE:
Our aim in this study was to explore the multiple mediating roles of depressive symptoms and social support in the relationship between insomnia and cognitive frailty.METHODS:
We recruited 300 hospitalized older patients with CHF to participate in this study. The participants completed the Athens Insomnia Scale, Geriatric Depression Scale, Montreal Cognitive Assessment, FRAIL Scale, and Social Support Rating Scale. The mediation hypothesis was tested using a multiple mediation model and bootstrapping method.RESULTS:
In this study, 44% of the patients experienced insomnia, and 51.3% were in a state of cognitive frailty. Our main findings suggest that insomnia has an indirect effect on cognitive frailty through 2 pathways the multiple mediating effects of depressive symptoms and social support, and a single mediating effect of depressive symptoms. The direct effect of insomnia on cognitive frailty is also significant.CONCLUSIONS:
Older patients with CHF who experience insomnia tend to have more severe depressive symptoms, cognitive frailty, and poor social support. Thus, interventions to recognize insomnia early, improve depressive symptoms, and provide social support may reduce cognitive frailty in older patients with CHF. Longitudinal studies are necessary to further refine our findings and address the limitations of the current study.
