Associations of Sleep Quality and Frailty among the Older Adults with Chronic Disease in China: The Mediation Effect of Psychological Distress.

ABSTRACT: Frailty affects the elderly and leads to adverse health outcomes. Preliminary evaluations have suggested that sleep quality and psychological distress are predictors of frailty among older adults. However, the mechanisms by which sleep quality affect frailty had not been fully addressed in the previous research. This study aimed to explore the mediation effect of psychological distress on the association between sleep quality and frailty among the elderly with chronic diseases in rural China. A total of 2346 old adults were included in the analysis. Frailty status was measured by Fried Phenotype criteria. Sleep quality was assessed by Pittsburgh Sleep Quality Index (PSQI), and psychological distress was examined by Kessler Psychological Distress Scale (K10). Ordinal logistic regressions were performed to assess the relationships between sleep quality and frailty. Mediation test was also conducted by bootstrap method. The prevalence rate of frailty among the elderly with chronic diseases was 21% in rural China. Compared with the elder of robust status, respondents identified as having frailty have lower SES, less vigorous physical activity, and worse self-reported health status. Poor sleep quality was a significant predictor of frailty with mediators (OR = 1.44, 95% CI = 1.19-1.76). Mediation analysis suggested that psychological distress mediated 41.81% of total effect between sleep quality and frailty. This study indicated that poor sleep quality was significantly related to frailty, and psychological was a mediator of this association. However, we could not investigate causal relationships between variables since this was one cross-sectional study. These findings suggested that an early detection of sleep problems and also psychological disorders should be taken to prevent frailty among the rural older adults in China.

Project description:BackgroundPatients with pulmonary nodules (PNs) often suffer from the psychological burden of their disease and trap in sleep problems. This is insufficiently identified and addressed in clinical practice. The aim of this study was to investigate the psychological distress and sleep quality among PN patients and identify potential risk or protective factors for sleep quality.MethodsWe conducted a cross-sectional study, which included 731 PN patients who visited the thoracic clinic of Guangdong Provincial People's Hospital. Each participant completed a structured questionnaire consisting of demographic characteristics, clinical characteristics, the Hospital Anxiety and Depression Scale (HADS) and the Pittsburgh Sleep Quality Index (PSQI). The reliability of the HADS (Cronbach's α = 0.944) and PSQI (Cronbach's α = 0. 0.757) in this study was satisfactory.ResultsA total of 328 patients (44.9%) had PSQI global scores > 5, indicating poor quality of sleep. Age ≥ 50 years (OR 1.88, 95% CI 1.35-2.58; P < 0.001), female (OR 1.56, 95% CI 1.05-2.33; P = 0.028), detection of nodule for 7-12 months (vs for more than 24 months, OR 2.14, 95%CI 1.18-3.89, P = 0.013), anxiety (OR 1.78, 95% CI 1.17-2.71; P = 0.007) and depression (OR 1.84, 95% CI 1.16-2.92; P = 0.010) were independent risk factors for impaired sleep quality. A significant correlation revealed that sleep quality was positively correlated with both anxiety and depression (Spearman r = 0.342, P < 0.001 and Spearman r = 0.314, P < 0.001, respectively). All dimensions of the PSQI scale were significantly decreased in both anxiety group and depression group compared to the psychologically normal group (P < 0.05).ConclusionsImpaired sleep quality is highly prevalent among patients with PNs and associated with age, gender, time from the date of detection, anxiety and depression. Based on the finding of impaired sleep quality and psychological health, screening for psychological and sleep problems in PN patients will be of great clinical benefit.
