Abstract

Abstract: Objective To compare the association patterns of overall sleep quality and its related factors with depressive symptoms between older adults with mild cognitive impairment (MCI) and those with dementia in nursing homes. Methods This cross-sectional study enrolled 522 institutionalized older adults with cognitive impairment. Cognitive function, sleep quality, and depressive symptoms were assessed using the Mini-Mental State Examination (MMSE), the Pittsburgh Sleep Quality Index (PSQI), and the 15-item Geriatric Depression Scale (GDS-15), respectively. Multivariable logistic regression analysis was employed to investigate the correlation between specific sleep-related factors and depressive symptoms. Results Of the 522 participants, 60.0% (n=313) were classified as having MCI and 40.0% as having dementia. The overall prevalence of sleep disturbances was 40.2%. The prevalence of sleep disturbances and the use of hypnotic agents were significantly higher in the MCI group compared to the dementia group (P<0.05). After adjusting for general characteristics, multivariate logistic regression analysis revealed that in the MCI group, experiencing nightmares and pain were significantly associated with depressive symptoms(P<0.05); In the dementia group, nocturnal awakening or early morning awakening, difficulty breathing, loud snoring or coughing, feeling cold, and feeling hot were significantly associated with depressive symptoms(P<0.05). Conclusions There are signifant differences in sleep quality and in association pattrerns sleep disorder manifestations and depressive symptoms among older adults with MCI compared to those with dementia in nursing homes.These findings suggest that tailored sleep intervention strategies, based on the stage of cognitive impairment, are necessary for the effective prevention and management of depressive symptoms.
