Objectives: the current study aimed to investigate the relationship between physical activity (PA) level and inhibitory control performance and then to determine whether this association was mediated by multiple sleep parameters (i.e., subjective sleep quality, sleep duration, sleep efficiency, and sleep disturbance). Methods: 180 healthy university students (age: 20.15 ± 1.92 years) from the East China Normal University were recruited for the present study. PA level, sleep parameters, and inhibitory control performance were assessed using the International Physical Activity Questionnaire (IPAQ), the Pittsburgh Sleep Quality Index Scale (PSQI), and a Stroop test, respectively. The data were analyzed using structural equation modeling. Results: A higher level of PA was linked to better cognitive performance. Furthermore, higher subjective sleep quality and sleep efficiency were associated with better inhibitory control performance. The mediation analysis revealed that subjective sleep quality and sleep efficiency mediated the relationship between PA level and inhibitory control performance. Conclusion: our results are in accordance with the literature and buttress the idea that a healthy lifestyle that involves a relatively high level of regular PA and adequate sleep patterns is beneficial for cognition (e.g., inhibitory control performance). Furthermore, our study adds to the literature that sleep quality and sleep efficiency mediates the relationship between PA and inhibitory control performance, expanding our knowledge in the field of exercise cognition.

Background and Objectives One of the most common complaint of tinnitus patients has been sleep disorder. The aim of this study was to evaluate the relationship between sleep disorder and tinnitus.Subjects and Method Patients with tinnitus from July 2018 till August 2019 were enrolled. Subjects who had any acute/chronic disease in the inner and middle ear or external auditory canal, sleep apnea and had more than 3 caffeinated beverages a day was excluded. Study participants completed Beck Depression Inventory (BDI), the tinnitus symptom questionnaire, tinnitus handicap inventory (THI), Pittsburg Sleep Quality Inventory (PSQI), pure tone audiometry, a full otologic examination and an interview on past medical history.Results THI was correlated with PSQI global score and BDI. The PSQI subscale most relevant to THI was PSQI 1 (subjective sleep quality). Hearing impairment was correlated with the THI functional subscale. BDI was individually related to PSQI.Conclusion Tinnitus is found to be highly related to sleep disorder, suggesting a common pathway of aggravation and treatment target. Tinnitus is also more affected by sleep disorder than by depression. A further examination and treatment of comorbid sleep disorder in tinnitus patients is recommended.

The Relationship

The relationship between objective and subjective sleep quality is still debated. Here, we investigate differences in objective sleep parameters in habitual subjective good sleepers and bad sleepers with the aim of evaluating sleep continuity, stability and organization as possible determinants of subjective sleep quality. In total, 38 subjects (good sleepers, N = 18; bad sleepers, N = 20) underwent two nights of sleep recording. Traditional sleep parameters displayed no between-groups differences. Conversely, bad sleepers showed lower sleep continuity (awakenings frequency), stability (e.g. arousals and state transitions frequency) and organization (e.g. number of sleep cycles and time spent in cycles). Our findings point to the involvement of these measures in determining habitual sleep quality perception and suggest the possibility to include them in standard sleep assessments.

Abstract Introduction Research has found relationships between sleep quality and personality traits. Poor subjective sleep quality has been observed within individuals scoring high in Neuroticism and low in Conscientiousness. Personality traits have also been associated with cognitive functioning and the link being worse cognition and poor sleep quality is established. However, less is known regarding the role of cognitive functioning in the relationship between personality and sleep quality, particularly in aging populations. This study investigated whether subjective cognition acted as a mediator between individual personality traits and subjective sleep quality in middle-aged and older adults. Methods Middle-aged and older adults (N=269; Mage= 64.5, SD=7.8; 123 women/146 men) who were cognitively healthy completed an online survey through Qualtrics measuring demographics, personality (Big Five Inventory-10; BFI-10), self-reported sleep (Pittsburgh Sleep Quality Index; PSQI), and subjective everyday cognition (Cognitive Failures Questionnaire; CFQ). Separate mediation analyses using SPSS PROCESS macro [and testing for indirect effects using 5,000 bootstrapped samples and 95% Confidence Interval (CI) and controlling for conditional associations among all pathways] examined whether subjective everyday cognition (CFQ scores) mediated the relationship between different personality traits (BFI-10 Conscientiousness and Neuroticism scores) and self-reported sleep (PSQI-Total Score), controlling for age and sex. Results Neuroticism and PSQI-Total Score was partially mediated by CFQ. There was a significant association between Neuroticism and total PSQI (total effect=0.588, SE=0.110, p<0.001). There were positive associations between Neuroticism and CFQ (a-path effect=2.765, SE=0.383, p<0.001) and CFQ and PSQI (b-path effect=0.068, SE=0.017, p<0.001). The indirect effect was significant (effect=0.187, SE=0.054, 95% CI=0.088 to 0.301). There was no association between Conscientiousness and PSQI-Total Score (total effect=-0.123, SE=0.133, p=0.358), therefore mediation analysis (testing of CFQ as a mediator) was discontinued. Conclusion In middle-aged and older adults, subjective everyday cognition mediates the relationship between Neuroticism personality trait and self-reported sleep quality. Individuals scoring higher in Neuroticism report worse subjective sleep quality as their subjective cognitive failures increase. Findings underscore the interacting roles of personality and everyday cognition on perceived sleep. Clinicians should consider individual personality profiles (via personality assessments) and subjective everyday cognitive ratings for a better understanding of the factors impacting middle-aged and older adults’ sleep profiles.
