“…Second, the EQ-5D is constrained by significant ceiling effects in measuring HRQOL in the general population. 27,29 We also found a high prevalence of good sleep quality in our sample, which is supported by prior studies in mainland China. 23,33 This can be explained by reports suggesting that most generally healthy older adults experience satisfactory …”

Study Objectives: To determine the associations of self-reported sleep quality and duration with health-related quality of life (HRQOL) in older Chinese. Methods: We analyzed community-based cross-sectional data of 5,539 individuals aged 60 years and older in the Weitang Geriatric Disease Study. Information of sleep quality and duration were self-reported through participants' responses to predefined questions; HRQOL data were collected by using the European Quality of Life-5 Dimensions (EQ-5D). We estimated the associations of sleep quality and duration with the EQ-5D index and visual analog scale (VAS) scores using linear regression models. The associations between sleep quality and duration and EQ-5D-detected health problems were modeled using logistic regression. Results: In multiple linear models adjusting sociodemographic factors, health conditions, and lifestyle habits, both EQ-5D index and VAS scores declined with deterioration of sleep quality. The coefficients for poor and intermediate sleep quality were −0.053 (95% confidence interval [CI]:−0.065, −0.042) and −0.022 (95% CI: −0.030, −0.013), respectively, in relation to EQ-5D index score. They were −5.2 (95% CI: −6.7, −2.4) and − 3.8 (95% CI: −4.9, −2.7) in modeling the EQ-5D VAS score. HRQOL declined as sleep duration decreased below 7.01 hours or exceeded 8.01 hours, though most of the associations did not reach statistical significance. In multiple logistic models, poor sleep quality was associated with problems of mobility, pain/discomfort, and anxiety/ depression; short sleep duration was associated with mobility problems. Conclusions: Poor sleep quality and extreme sleep durations appeared to be negatively associated with HRQOL in older Chinese adults.

“…This is consistent with previous studies in mainland China. [27][28][29][30] Two facts may account for this finding. First, the survey participants lived a normal life at home, which implies better HRQOL than those who live in medical institutions for professional care.…”

“…Finally, because this analysis was conducted on a cohort of Chinese patients from a larger patient population of East Asian patients (that included patients from mainland China, Hong Kong, Korea, Malaysia, Singapore and Taiwan), and there is no Chinese EQ-5D tariff, the commonly used UK tariff was used to calculate the utility scores (Brooks et al 2003). While there is evidence that different populations (including different racial/ethnic groups) value health states differently (Escobar et al 1983;Johnson et al 2005;Fu and Kattan 2006;Norman et al 2009), the EQ-5D has been shown to be useful for assessing QoL in patients with MDD (Sapin et al 2004) and to have acceptable validity and reliability in Asian populations (Wang et al 2012). In addition, both EQ-VAS and EQ-5D utility scores have been shown to be responsive to change in patients with depression (Günther et al 2008;Gerhards et al 2011).…”

“…The questionnaire was designed to capture information on the consumption of major nutrients as well as specific Chinese foods, such as soy foods, fermented foods, salted foods, allium-type vegetables, and leafy vegetables; (4) the Zung Self-Rating Anxiety Scale (ZSAS) [9] and the Center for Epidemiologic Studies Depression Scale (CESD) [10] were used to determine mood for each subject. Anxiety and depression were present if ZSAS >44 and CESD ≥16; (5) the Pittsburgh Sleep Quality Index (PSQI) was used to measure the sleep quality of the participants [11]; (6) the EQ-5D was used to measure the health outcome of the participants [12]; (7) items from the Lawton and Brody Activity of Daily Living (ADL) scale-16 were used to elicit physical self-maintenance and instrumental activities of daily living, such as eating, using the telephone, preparing meals, handling money, and completing chores. Participants were considered to be functionally intact if the ADL score was over 16 [13].…”

Background: To establish a prospective cohort to enumerate the prevalence, incidence and risk factors for dementia and mild cognitive impairment (MCI) among residents aged ≥60 in an urban community of Shanghai, China. Methods: Participants received clinical evaluations including physical measurements, demographic and lifestyle questionnaires, physical and neurologic examinations, and neuropsychological testing. Urine and blood samples were collected, aliquoted, and stored. DNA was extracted for Apolipoprotein (APOE) genotyping. Diagnoses of dementia and MCI were made using standard criteria via consensus diagnosis. Results: Among 3,141 participants aged ≥60, 1,438 (45.8%) were men. The average age of participants was 72.3 years (SD 8.1), and they had an average of 11.6 years (SD 4.4) of education. The most common chronic disease of participants was hypertension (56.4%). The frequencies of APOE-ε2, ε3 and ε4 were 7.9, 82.7 and 9.4%, respectively. We diagnosed 156 (5.0%, 95% CI 4.3-5.8%) participants with dementia. The prevalence rates of Alzheimer's disease and vascular dementia were 3.6% (95% CI 3.0-4.3%) and 0.8% (95% CI 0.5-1.1%). Conclusions: The Shanghai Aging Study is the first prospective community-based cohort study of cognitive impairment in China, with a comparable study design, procedures, and diagnostic criteria for dementia and MCI to most previous cohort studies in developed countries.
