Sleep disturbance and frailty have been shown to exert independent effects on depression. Little has been known about their combined effects. Evidence suggests they could be explained by shared neural or physio mechanisms, researchers say. It's unclear whether the combined effect of frailty and sleep duration is greater than the sum of its parts, they say.

Researchers sought to evaluate the effects of baseline and changes in frailty states on subsequent depressive symptoms. They analyzed data of 5,026 community-dwelling adults aged 60 or older at baseline who participated in the 2011 and 2013 waves of the China Health and Retirement Longitudinal Study.

Results showed an association between baseline prefrail and frail states and higher subsequent levels of depressive symptoms 2 years later. Transitioning into frail was linked to higher levels of depressive symptoms among individuals who were prefrail at baseline. Short sleep duration accelerated this association. Those who reported short sleep duration exhibited this association more strongly.

"More clinical attention should be paid to the care of frail and prefrail older persons," the researchers wrote. Exercise training and mindfulness-based stress reduction could help alleviate the effects of frailty on psychological well-being, they said.
