“…Studies have showed that in comparison with normal sleep duration (7–9 h for adults), either short and long sleep duration had potential to raise the risk of depression ( 26 ). Sufficient sleep duration can assist older people in performing both physical and psychological functions adequately ( 27 ). Thus, sleep duration may play a moderating role between ADL and depressive symptoms.…”

IntroductionPrevious studies have demonstrated that frailty is associated with depressive symptoms among older people and significantly increase the risk of difficulty in activities of daily living (ADL). However, uncertainties remain regarding the mechanisms behind such relationship. The aim of this study was to investigate the mediating effect of ADL in the relationship between frailty and depressive symptoms among older adults in China, and to explore to what extend sleep duration moderated the association between ADL and depressive symptoms.MethodsIn this study, we carried out cross-sectional descriptive analysis and 1,429 participants were included in the analysis. A survey was conducted using questionnaires and instruments measuring frailty, depressive symptoms, ADL and sleep duration. Bootstrap analyses served to explore the impact of ADL in mediating frailty and depressed symptoms, as well as the effect of sleep duration in moderating ADL and depressive symptoms.ResultsCompared to the robust group, the mediating effects of ADL between frailty and depressive symptoms were significant in the prefrail group and the frail group. The interaction term between sleep duration and ADL was significantly presented in the regression on depressive symptoms. Specifically, the Johnson–Neyman technique determined a range from 8.31 to 10.19 h for sleep duration, within which the detrimental effect of frailty on depressive symptoms was offset.ConclusionSleep duration moderated the indirect effect of ADL on the association between frailty and depressive symptoms. This provides support for unraveling the underlying mechanism of the association between frailty and depressive symptoms. Encouraging older adults to enhance ADL and obtain appropriate sleep duration might improve depressive symptoms for older adults with frailty and prefrailty.

Background Both long and short sleep durations may lead to cognitive decline in the elderly individuals, though the underlying mechanisms remain unclear. Aims To explore the mediating mechanism of activities of daily living and depression on different sleep durations and cognitive function in older Chinese older adults. Methods This retrospective study used data from 5,899 older adults who completed the 2018 China Health and Retirement Longitudinal Surveys. We used the PROCESS macro in SPSS to determine the chain mediating effect of ADL and depression on the relationship between different sleep durations and cognitive functions. Results (1) There were significant correlations among sleep duration, ability to perform ADL, depression, and cognitive function. (2) For sleep durations ≤ 7 h/night or > 7 h/night, ADL and depression play a chain mediating role in the relationship between sleep duration and cognitive function. Conclusions Shorter or longer sleep durations were associated with cognitive decline by weakening ADL and worsening depression, which suggests that medical personnel should take action to correct abnormal sleep duration in older adults. Timely treatment of ADL impairment and depression may help prevent cognitive decline.
