Tobit and multivariate logistic regression models were used to determine the association between sleep quality and duration and HRQoL. HRQoL was assessed using the European Quality of Life-5 Dimensions. This study aimed to determine the association between sleep quality and duration and HRQoL among the elderly in the United Kingdom, assess whether depression mediated the association, and explore the role of physical activity (PA) in the path association.ĭata were extracted from the baseline survey of the UK Biobank, a large prospective cohort study enrolling more than 500,000 participants, of which 52,551 older adults (aged ≥60 years) were included in the study. In addition, few studies have explored the path mechanism of sleep disorders leading to impaired HRQoL. Many of these associations persisted over the 10-year period of the study, and there was little evidence for gender differences or multiplicative interactions.Īlthough studies have shown that sleep quality (duration) is associated with health-related quality of life (HRQoL), most of these studies have been small-sized and targeted at young and middle-aged adults. The remaining associations were near-zero in their effect sizes. Partner orderliness was associated with better health and more positive health behavior. With a sample of 3,271 couples (N=6,542) from the Health and Retirement Study, we found that actor conscientiousness, orderliness, and industriousness were most reliably associated with better health outcomes over time. Applying the actor–partner interdependence model, we examined dyadic associations of broader conscientiousness and its six facets and changes in health, health behavior, and well-being in middle-aged and older couples. However, less is known about how various facets of conscientiousness, of both individuals and their partners, are associated with changes in health in older adults over time. Previous studies show consistent associations between conscientiousness and health outcomes. This information might be considered when providing lifestyle recommendations to adults with and without cognitive complaints. Our data confirm the absence of association between napping and global cognition and memory regardless of the characteristics of the population. These associations were not modified by individual or sleep characteristics. The pooled ORs from the longitudinal analyses were 1.00 (95% 0.85 to 1.18) for global cognition and 1.08 (95% 0.98 to 1.19) for memory. The pooled ORs from the cross-sectional analyses were 1.03 (95% CI: 1.01 to 1.06) for global cognition and 1.06 (95%: 0.90 to 1.26) for memory. Twenty-five studies were included in this systematic review and meta-analysis, 18 cross-sectional and seven longitudinal studies, including 95,719 participants older than 60 years. The mean age, the night sleep time (hours), and the percentage of women, no nappers, and people in the less night-time sleep duration category were used for meta-regressions. DerSimonian and Lair and Hartung-Knapp-Sidik-Jonkman random effects methods were used to compute pooled estimates of odds ratios (ORs) and their respective 95% confidence intervals (95% CIs) for the association of global cognition and memory with napping. We systematically searched Medline (via PubMed), Web of Science, and Scopus. This systematic review and meta-analysis aimed to elucidate the cross-sectional and longitudinal relationships between napping and cognitive function (global cognition and memory) and to explore whether some individual characteristics and sleep characteristics can modify this relationship. No clear evidence is available for the influence of napping on cognitive function in older adults.
