Abstract:
ObjectiveTo investigate the relationship of physical activity (PA) and cognitive function to sleep quality in older adults with cognitive impairment based on resting electroencephalogram (EEG), and to explore the mediating role of specific EEG markers in the relationship between PA and sleep quality. MethodsFrom March to May, 2024, 137 older adults were recruited from Chenfu Jiayuan and Qiangwei Jiuli in Songjiang district, and Luyan communities in Jinshan district, Shanghai. The assessments included Montreal Cognitive Assessment (MoCA), International Physical Activity Questionnaire-Short Form (IPAQ-SF) and Pittsburgh Sleep Quality Index (PSQI), along with a five-minute EEG recording. ResultsThere was significant difference in sleep quality among older adults with different levels of cognitive impairment (t = -7.400, P < 0.001). The PSQI total score was negatively correlated with MoCA scores (r = -0.412, P < 0.001) and total physical activity level (PAL) (r = -0.363, P < 0.001). The θ power in the frontal areas (F3, F4) was significantly correlated with both PSQI scores and PAL (P < 0.01). The θ power in F3 + F4 exhibited a significant partial (effect size = -0.0004, 95%CI -0.0007 to -0.0002) mediating effect between PA and sleep quality in older adults with cognitive impairment. ConclusionOlder adults with more severe cognitive impairment tend to have poorer sleep quality, whereas higher PAL is associated with better sleep quality. PA can indirectly influence sleep quality in older adults with cognitive impairment by affecting θ power (F3 + F4).
